Method of fitting fastener to object

Abstract

A method of fitting a fastener to an object is introduced. The fastener has a weldable surface and an engaging portion or a hole portion. One end of the hole portion or one end of the engaging portion has a holding portion. During a welding heating process, solder flows into or enters the holding portion and then cools down and solidifies therein so as to be held therein. Therefore, the weldable surface and the holding portion together enable the fastener to be firmly coupled to an object. The engaging portion and the hole portion together enable an object to be coupled to or removed from another object, so as to couple together and separate at least two objects repeatedly and quickly.

DETAILED DESCRIPTION OF THE INVENTION

(28) To facilitate understanding of the object, characteristics and effects of this present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided.

(29) Referring to FIG. 1 and FIG. 2, the present disclosure provides a method of fitting a fastener 1 to an object. The fastener 1 has a weldable surface 11 and an engaging portion 12 and a hole portion 13. One end of the hole portion 13 or one end of the engaging portion 12 has a holding portion 14. During a welding heating process, molten solder flows into the holding portion 14. Then, the solder in the holding portion 14 cools and thus turns into solid-state solder 7 so as to be held in the holding portion 14.

(30) The fitting process begins by welding the fastener 1 to a first object 2. The first object 2 has a corresponding weldable surface 21. During the heating process, the solder between the weldable surface 11 and the corresponding weldable surface 21 turns into liquid state, such that the liquid-state solder flows into the holding portion 14. Then, the liquid-state solder in the holding portion 14 cools and thus turns into the solid-state solder 7 so as to be held in the holding portion 14. After that, the engaging portion 12 or the hole portion 13 engages with a second object 3, or the engaging portion 12 and the hole portion 13 are engaged to the second object 3. Thus, with the holding portion 14 being adapted to receive the liquid-state solder and then hold the solid-state solder 7, the liquid-state solder does not flow into the hole portion 13 or the engaging portion 12, cool and solidify. Thus, the solidified solder is unlikely to fall off, because it is impossible for interference or impacts to happen when the second object 3 engages with or enters the hole portion 13 or the engaging portion 12. Therefore, the weldable surface 11 and the holding portion 14 together enable the fastener 1 to be firmly coupled to the first object 2, whereas the engaging portion 12 and the hole portion 13 together enable the first object 2 to be coupled to or removed from the second object 3, so as to couple together and separate at least two objects repeatedly and quickly.

(31) In a preferred embodiment of the present disclosure, the fastener 1 has a joining portion 15. The joining portion 15 has a weldable surface 11. The joining portion 15 and the weldable surface 11 together enable the fastener 1 to be welded to the first object 2. Both the holding portion 14 and the joining portion 15 have a weldable surface, or the fastener 1 is fully enclosed by a weldable surface (not shown), thereby allowing the present disclosure to meet different usage needs.

(32) In a preferred embodiment of the present disclosure, the joining portion 15 is adapted to be welded to a penetrating hole 22 of the first object 2 from inside or from outside, so as to be welded to a flat surface at one end of the first object 2. According to the present disclosure, the joining portion 15 is adapted to be welded to the penetrating hole 22 of the first object 2, such that the fastener 1 is firmly coupled to the first object 2.

(33) In a preferred embodiment of the present disclosure, the engaging portion 12 is a thread (for example, internal thread or external thread, preferably internal thread in this embodiment). The engaging portion 12 may also be a hole member or slot member (not shown). The hole portion 13 is a penetrating hole. The holding portion 14 and the joining portion 15 are step portions. Therefore, the fastener 1 engages with the second object 3 through the engaging portion 12 and the hole portion 13.

(34) In a preferred embodiment of the present disclosure, the fastener 1 is adapted to be welded to the first object 2, and the first object 2 is a printed circuit board (PCB), metal board or plastic board. Therefore, according to the present disclosure, the fastener 1 is applicable to various first object 2, thereby allowing the present disclosure to meet practical fitting-related needs.

The hole portion 13 is a penetrating hole. The holding portion 14 is in the shape of a slope, and the joining portion 15 is a step portion. Therefore, the fastener 1 is adapted to be welded to the first object 2. Solder between the weldable surface 11 and the corresponding weldable surface 21 turns into liquid state when heated up. The liquid-state solder flows into the holding portion 14 which is in the shape of a slope, such that the liquid-state solder cools and thus turns into the solid-state solder 7 so as to be held in the holding portion 14. Then, the engaging portion 12 or the hole portion 13 engages with a second object (not shown), or the engaging portion 12 and the hole portion 13 are engaged to the second object. Therefore, the fastener 1 can be provided in various forms in order to be applicable to the first object 2 and the second object, thereby allowing the present disclosure to meet different usage needs.

Therefore, the fastener 1 is adapted to be welded to the first object 2. Solder between the weldable surface 11 and the corresponding weldable surface 21 turns into liquid-state solder when heated up. The liquid-state solder flows into the holding portion 14 which is in the shape of a slope, such that the liquid-state solder cools and thus turns into the solid-state solder 7 so as to be held in the holding portion 14. Then, the engaging portion 12 or the hole portion 13 engages with a second object (not shown), or the engaging portion 12 and the hole portion 13 are engaged to the second object.

The liquid-state solder flows into the holding portion 14 which is a step portion, such that the liquid-state solder cools and thus turns into the solid-state solder 7 so as to be held in the holding portion 14. Then, the engaging portion 12 or the hole portion 13 engages with a second object (not shown), or the engaging portion 12 and the hole portion 13 are engaged to the second object.

(40) Referring to FIG. 11, in a preferred embodiment of the present disclosure, the engaging portion 12 is a thread (for example, internal thread or external thread, preferably internal thread in this embodiment). The hole portion 13 is a non-penetrating hole. The holding portion 14 is a step portion. The joining portion 15 is a plane portion.

The hole portion 13 is a non-penetrating hole. The holding portion 14 is in the shape of a slope, and the joining portion 15 is a plane portion. Therefore, the fastener 1 can be provided in various forms in order to be coupled to the first object (not shown), whereas the engaging portion 12 and the hole portion 13 engage with the second object (not shown), thereby allowing the present disclosure to meet different usage needs.

(42) Referring to FIG. 13, in a preferred embodiment of the present disclosure, the engaging portion 12 and the hole portion 13 are penetrating holes in communication with each other. The holding portion 14 is in the shape of a slope, and the joining portion 15 is a step portion.

The holding portion 14 is a step portion. The joining portion 15 is a plane portion. Therefore, the fastener 1 is adapted to be welded to the first object 2. Solder between the weldable surface 11 and the corresponding weldable surface 21 turns into liquid-state solder when heated up. The liquid-state solder flows into the holding portion 14 which is a step portion, such that the liquid-state solder cools and thus turns into the solid-state solder 7 so as to be held in the holding portion 14.

Therefore, the fastener 1 can be provided in various forms in order to be applicable to the first object 2 and the second object 3, thereby allowing the present disclosure to meet different usage needs.

(44) Referring to FIG. 15, in a preferred embodiment of the present disclosure, the engaging portion 12 and the hole portion 13 are two penetrating holes in communication with each other. The holding portion 14 is a step portion. The joining portion 15 is a plane portion.

(45) Alternatively, the holding portion 14 is an arcuate surface, curved surface, slot, dent or hole, whereas the joining portion 15 is a raised portion, dented portion, arcuate surface portion or curved surface portion (not shown). Therefore, the present disclosure meets different usage needs.

(46) Referring to FIG. 16, in a preferred embodiment of the present disclosure, the fastener 1 is carried with a carrier 4 and taken out thereof with a tool 5; then, the fastener 1 is positioned at the penetrating hole 22 of the first object 2 to undergo welding.

(47) In a preferred embodiment of the present disclosure, the carrier 4 has a lid 41. The lid 41 hides the fastener 1 in the carrier 4.

(48) In a preferred embodiment of the present disclosure, the tool 5 is a clamping component, evacuating device or magnetic attracting device. Therefore, the tool 5 is appropriately selected in accordance with usage needs, thereby allowing the present disclosure to meet practical fitting-related needs.

(49) Referring to FIG. 17, in a preferred embodiment of the present disclosure, the fastener is carried with a carrier 4 and taken out thereof with a tool 5; then, a comparison device 6 compares the fastener 1 with the first object 2 in terms of position and sends a position message to the tool 5, thereby allowing the fastener 1 to be precisely positioned at a welding position (for example, the penetrating hole 22 shown in the diagram) of the first object 2 with the tool 5.

(50) In a preferred embodiment of the present disclosure, the comparison device 6 is an image comparison device, vision comparison device, distance comparison device or space comparison device. Therefore, the comparison device 6 is selected as needed to meet practical usage needs.

(51) Referring to FIG. 18, in a preferred embodiment of the present disclosure, the fastener 1 has an interposer 16. The fastener 1 is carried with a carrier 4 and taken out thereof with a tool 5 through the interposer 16; then, the fastener 1 is positioned at the penetrating hole 22 of the first object 2 to undergo welding.

(52) In a preferred embodiment of the present disclosure, a solder layer 23 (or weldable layer), intended to be heated and then cooled to solidify, is disposed between the weldable surface 11 of the fastener 1 and the corresponding weldable surface 21 of the first object 2, such that the weldable surface 11 of the fastener 1 and the corresponding weldable surface 21 of the first object 2 can be welded together by the solder layer 23.

(53) Referring to FIG. 19, in a preferred embodiment of the present disclosure, the fastener 1 has an interposer 16. The fastener 1 is carried with a carrier 4 and taken out thereof with a tool 5 through the interposer 16. Then, a comparison device 6 compares the fastener with the first object 2 in terms of position and sends a position message to the tool 5, thereby allowing the fastener 1 to be precisely positioned at a welding position (for example, the penetrating hole 22 shown in the diagram) of the first object 2 with the tool 5.

Therefore, the interposer 16 meets practical usage needs.

(57) Referring to FIG. 23, in a preferred embodiment of the present disclosure, the present disclosure further provides a method of fitting a fastener 1 to an object. The fastener 1 has a weldable surface 11, an engaging portion 12 and a hole portion 13. The method comprises the steps of: providing a tool 5 for gripping the fastener 1; moving the fastener 1 to a predetermined height a above a fitting position (i.e., penetrating hole 22) of the first object 2 with the tool 5; and causing the tool 5 to release or loosen its grip on the fastener 1, thereby allowing the fastener 1 to descend and land on the fitting position of the first object 2.

(58) Thus, the fastener 1 is fixed to the first object 2 to enhance the efficiency of subsequent processes.

(59) In an embodiment of the present disclosure, the fastener 1 is disposed in a carrier 4. The fastener 1 is taken out of the carrier 4 with a tool 5, and then a comparison device 6 compares the fastener 1 with the corresponding weldable surface 21 at the fitting position 20 of the first object 2 in terms of position or distance. Thus, the tool 5 moves the fastener 1 to a predetermined height a (from 0.000001 mm to 10 mm) above the corresponding weldable surface 21 of the first object 2 according to the comparison message of the comparison device 6 and then releases or loosens its grip on the fastener 1, such that the fastener 1 descends and lands on the corresponding weldable surface 21 at the fitting position 20 of the first object 2. After that, the weldable surface 11 of the fastener 1 and the corresponding weldable surface 21 of the first object 2 are heated up and welded together, allowing the fastener 1 to be welded to the first object 2. The first object 2 is a PCB, and a penetrating hole 22 is disposed at the fitting position of the first object 2. The fastener 1 is disposed in the penetrating hole 22.

(60) In an embodiment of the present disclosure, the method comprises the steps of: providing a comparison device 6 for comparing the fastener 1 with the first object 2 in terms of its fitting position or fitting distance after the tool 5 has gripped the fastener 1; moving the fastener 1 to the predetermined height a above the fitting position of the object with the tool 5 according to a comparison message of the comparison device 6; and causing the tool 5 to release or loosen its grip on the fastener 1, such that the fastener 1 descends and lands on the fitting position of the first object 2.

(61) In an embodiment of the present disclosure, the method comprises the steps of: providing, after the tool 5 has gripped the fastener 1, a comparison device 6 for comparing the fastener 1 with a corresponding weldable surface 21 at the fitting position of the first object 2 in terms of position or distance; moving the fastener 1 to the predetermined height a above the corresponding weldable surface 21 of the first object 2 with the tool 5 according to a comparison message of the comparison device 6; and causing the tool 5 to release or loosen its grip on the fastener 1, such that the fastener 1 descends and lands on the corresponding weldable surface 21 of the first object 2.

(62) In an embodiment of the present disclosure, the tool 5 is a clamping component, engaging component, evacuating device, magnetic attracting device or resilient motion component, thereby allowing the present disclosure to meet practical fitting-related needs.

(63) In an embodiment of the present disclosure, the comparison device 6 is a vision comparison device, distance comparison device, image comparison device, AI comparison device or photograph comparison device, thereby allowing the present disclosure to meet practical fitting-related needs.

(64) Referring to FIG. 24, in a preferred embodiment of the present disclosure, the present disclosure further provides a method of fitting a fastener 1 to an object. The fastener 1 has a weldable surface 11, an engaging portion 12 and a hole portion 13. The method comprises the steps of: providing a tool 5 for gripping the fastener 1; moving the fastener 1 to a fitting position of the first object 2 with the tool 5; and causing the tool 5 to sense a feedback message indicative of the fastener 1 having come into contact with the first object 2 and then release or loosen its grip on the fastener 1, such that the fastener 1 is positioned at the fitting position of the first object 2, thereby allowing the fastener 1 to be welded to the weldable surface 21 of the first object 2.

(65) The tool 5 has a sensing member 51 (for example, a resilient sensing member). After the tool 5 has moved the fastener 1 to the fitting position of the first object 2 and the sensing member 51 of the tool 5 has sensed a feedback message indicative of the fastener 1 having come into contact with the first object 2, the tool 5 releases or loosens its grip on the fastener 1, such that the fastener 1 is positioned at the fitting position of the first object 2, thereby allowing the present disclosure to meet practical fitting-related needs.

(66) In an embodiment of the present disclosure, after the fastener 1 has come into contact with the first object 2, electrical conduction therebetween comes into play. The sensing member 51 senses the electrical conduction and thus generates a feedback message. The feedback message causes the tool 5 to release or loosen its grip on the fastener 1.

(67) In an embodiment of the present disclosure, when the fastener 1 is fitted to the first object 2 as described above, the joining portion 15 has a stopping element 8. The stopping element 8 stops the liquid-state solder on the weldable surface 21 from entering or flowing into the engaging portion 12 (or the hole portion 13). After the solder has cooled down to thereby fit the fastener 1 to the first object 2 firmly, the stopping element 8 is removed from the joining portion 15 with a tool 9 to thereby restore the joining function of the engaging portion 12 (or the hole portion 13).

(68) Regarding the method of fitting the fastener 1 to an object according to the present disclosure, the tool 5 grips the fastener 1, such that the tool 5 moves the fastener 1 to the fitting position of the first object 2, and the tool 5 presses the fastener 1 downward against the first object 2, thereby allowing the tool 5 to release or loosen its grip on the fastener 1. Thus, the fastener 1 is positioned at the fitting position of the first object 2, thereby allowing the present disclosure to meet practical fitting-related needs.

(69) Regarding the method of fitting the fastener 1 to an object according to the present disclosure, the tool 5 grips the fastener 1, such that the tool 5 moves the fastener 1 to a fitting position of the first object 2 and presses resiliently the fastener 1 downward against the first object 2, thereby causing the tool 5 to release or loosen its grip on the fastener 1. Thus, the fastener 1 is positioned at the fitting position of the first object 2, thereby allowing the present disclosure to meet practical fitting-related needs.

(70) Referring to FIG. 25, in a preferred embodiment of the present disclosure, a resilient component 52 disposed in the tool 5 enables the tool 5 to grip the fastener 1 under the evacuating force of the tool 5. Thus, the tool 5 moves the fastener 1 to the fitting position of the first object 2, resiliently presses the fastener 1 downward against the first object 2, and compresses the resilient component 52 to therefore terminate the evacuating force and restore the resilient component 52 to its initial position, thereby allowing the tool 5 to release or loosen its grip on the fastener 1 and allowing the fastener 1 to be positioned at the fitting position of the first object 2. After the solder on the weldable surface 21 has cooled down and fitted the fastener 1 to the first object 2 firmly, removal of the stopping element 8 allows the joining function of the engaging portion 12 (or the hole portion 13) to restore, thereby allowing the present disclosure to meet practical fitting-related needs.

(71) Referring to FIG. 26, in a preferred embodiment of the present disclosure, there is a cooled-and-solidified solder layer (i.e., the cooled weldable surface 21) between the joining portion 15 and the penetrating hole 22 of the first object 2 or between the fastener 1 and the first object 2. The joining portion 15 of the fastener 1 has a rotation-preventing portion 151. The first object 2 has a corresponding rotation-preventing portion 24. The rotation-preventing portion 151 prevents the rotation of the corresponding rotation-preventing portion 24 and vice versa. Between the rotation-preventing portion 151 and the corresponding rotation-preventing portion 24 is a solder layer (i.e., the cooled weldable surface 21) conducive to enhancement of the strength of the bonding between the fastener 1 and the first object 2, such that the fastener 1 is joined to the first object 2 firmly.

(72) Referring to FIG. 27, the joining portion 15 is joined to a corresponding tightening element 17. The corresponding tightening element 17 is coupled to the engaging portion 12 (or the hole portion 13) to clamp the first object 2 and thus enhance the strength of the bonding between the fastener 1 and the object 2, such that the fastener 1 is fitted to the first object 2 firmly.

(73) While the present disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present disclosure set forth in the claims.
