DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Referring to FIG. 2, the main structure of the present invention includes: a slider 1, a main bracket 2, a pivot drive assembly 3, and a feeding mechanism 4; the sliding block 1 is disposed on a sliding rail mechanism 10, and the sliding rail mechanism 10 can be an end shaft of a working space, suitable for the end shaft of the mechanical arm to drive the sliding block 1 in a working space.

[0018] The main bracket 2 is vertically erected on the sliding block 1 via a pivoting seat 21 and extends at one end of the lower bracket 22, and a welding head 23 is disposed at the end of the lower bracket 22, and a pivoting drive assembly 3 is disposed on the sliding block 1 and coupled to the pivoting seat 21, so that the pivoting drive assembly 3 can pivot the main bracket 2 via the pivoting seat 21.

[0019] In a preferred embodiment, the pivoting drive assembly 3 can be a step motor or servo motor having a reduction gear set therein, and the main bracket 2 can be driven in the forward and reverse directions via the pivoting seat 21.

[0020] The feeding mechanism 4 is disposed at an end of the main bracket 2 away from the welding head 23. The feeding mechanism 4 has a feeding drive assembly 41 and a solder conduit 42 connected to each other, and a solder bracket 24 is disposed on the side of the feeding driving assembly 41. The solder holder 24 is provided with a solder roll 51 for pivoting a strip of solder 5; and the feed driving assembly 41 can receive the solder 5 sent from the solder roll 51 and introduce the solder 5 into the solder conduit 42, The solder conduit 42 extends to the side of the weld head 23 and forms a discharge port 43 for guiding the solder 5, so that the solder 5 derived from the discharge port 43 can be melted at a high temperature generated by the weld head 23 on the preset workpiece.

[0021] Referring to FIGS. 3 and 4, it can be seen that in the actual application, if a workpiece is to be processed on a U-shaped weld bead 90, and at the initial processing portion D, the discharge port 43 is disposed in front of the welding head 23 along the machining direction D1.

[0022] When the slide mechanism 10 drives the sliding block 1 to carry the welding head 23 to enter the processing portion E laterally, the pivot drive assembly 3 can be pivoted in the X direction or the opposite direction via the pivoting seat 21, and the main bracket 2 is pivoted so that the discharge port 43 can be kept in front of the welding head 23 in the machining direction E1.

[0023] When the sliding mechanism 10 drives the sliding block 1 to drive the welding head 23 to enter the processing portion F laterally, the pivoting drive assembly 3 can drive the main bracket 2 to pivot again via the pivoting seat 21 so that the discharge port 43 can be held in front of the welding head 23 in the machining direction F1.

[0024] In this way, during the processing of the weld bead 90, the discharge port 43 can be kept in front of the weld head 23 with various machining directions, so that the solder 5 is led out from the discharge port 43, and at the same time, the weld head 23 is also moved toward the discharge port 43, so that the solder 5 can smoothly extend beneath the weld head 23 and contact the workpiece thus to be effectively heated by the weld head 23. When the solder 5 is heated and welded onto the workpiece to form the weld bead 90, the weld bead 90 will at the same time smoothly pull the solder 5 in the same direction as drained from the discharge port 43 to obtain significant welding quality and weld bead morphology.

[0025] In summary, the welding filler feed-forward maintaining device of the present invention is provided to adjust the relative position of the discharge port and the welding head of the solder according to different machining directions, so that the discharge port is held in front of the welding head along the machining direction to ensure the maintenance of the best welding quality and weld bead morphology.

[0026] The scope of protection is limited solely by the claims, and such scope is intended and should be interpreted to be as broad as is consistent with the ordinary meaning of the language that is used in the claims when interpreted in light of this specification and the prosecution history that follows, and to encompass all structural and functional equivalents thereof.
