DETAILED DESCRIPTION
(25)
(26) Other cable processing machines for processing cables 15 (
(27) The crimping device 5 is designed to connect a crimp contact to a cable 15 by means of a crimp connection. The cables 15 that are processed or connected to the crimp contact are stored in a cable tray 20 of the cable processing machine 5 or the crimping device 5. The cable tray 20 can be tilted so that the cables 15 present in the cable tray 20, for example a production batch or a plurality of production batches of cables 15, fall into a lower-lying removal trough 22. The cable tray 20 and the removal trough 22 run parallel to one another and extend along a cable processing axis 6. The cables 15 are moved along in the cable processing machine 5 in the longitudinal direction of the cable tray 20, which is also referred to as the cable processing axis 6.
(28) The cable processing machine 5 assembles the cable 15, i.e. cuts the cable 15 off or cuts it through at a desired point in order to achieve a cable 15 of a predetermined cable length with two ends.
(29) To crimp the cable 15 with a crimp contact, part of the cable 15 is pivoted out of the cable processing axis 6 and guided to a crimping press 8 (which is shown on the left of the cable processing axis 6 in
(30) Further workstations to which the cable 15 is moved are possible.
(31)
(32)
(33) The handling robot 30 of the cable processing machine apparatus can be attached to the cable processing machine 5 or to the crimping machine or to the crimping device 5 or can be connected thereto. The handling robot 30 comprises a gripping unit 50 with a gripping arm 55. The gripping unit 50 or the gripping arm 55 can be moved linearly parallel to the cable processing axis 6 by means of a carriage 31 of the gripping unit 50. For this purpose, the handling robot 30 has a linear guide 32 (
(34) The handling robot 30 allows automation of a large number of processes that were previously carried out manually or by hand.
(35) The gripping arm 55 of the handling robot 30 can be moved on both sides of the cable processing machine 5 or crimping machine or crimping device 5, i.e. the left side and the right side in
(36) The gripping unit 50 can be moved back and forth along the linear guide 32 in the direction a. For this purpose, the crimping system 1 has a toothed belt drive 33 of the linear guide 32. A gripping arm 55 of the gripping unit 50 is attached to a rod 37 (
(37) By means of the pivot arm 39 of the gripping unit 50, the distance between the gripping arm 55 and the linear guide 32 can be changed. By a rotation along the double arrow b, the distance between the gripping arm 55 and the linear guide 32 can be increased or decreased. In addition, the gripping arm 55 can thereby be moved to the other side of the linear guide 32 or the crimping device 5. The rotation along the double arrow b can be carried out by a third toothed belt drive 38.
(38) The gripping arm 55 can pick up the cables 15 from the cable replacement device 110 and put them down again or hang them there. As a result, the cable 15 used by the crimping device 5 can be exchanged or replaced in an automated manner.
(39) The gripping arm 55 is operated pneumatically. The gripping arm 55 comprises two jaw carriers 63, 64 which close symmetrically. The gripping jaws 60, 61 fastened to the jaw carriers 63, 64 point towards one another in the open position which is shown in
(40) In the closed position of the gripping jaws 60, 61, which is shown in
(41) Both jaw carriers 63, 64 each have a flange element 65, 66 with holes. In the open position of the gripping jaws 60, 61, one of the flange elements 65, 66 is arranged, so to speak, on the rear side of a jaw. The flange elements 65, 66 are designed to grip and hold a cable processing cassette such as a crimping cassette 80 (
(42) In the closed position of the gripping jaws 60, 61, the flange elements 65, 66 are also in a closed position.
(43) A two-part cable gripper 70 which is designed to grip and hold individual cables 15, is arranged on one of the flange elements 65, 66 (on the right flange element 65 in
(44) The gripping arm 55 is designed to remove from the removal trough 22 batches of finished cables 15 or a plurality of finished cables 15 that have been conveyed from the cable tray 20 into the removal trough 22.
(45)
(46) The gripping arm 55 can remove the cables 15 from the removal trough 22 by means of the gripping jaws 60, 61 and, for example, transport them into a holding device, boxes or the like.
(47) The removal trough 22 can be moved pneumatically in the direction of the double arrow 24 in
(48) The removal trough 22 can be designed as a non-smooth channel and have a plurality of cutouts or depressions which make it easier to grasp the cables 15 located in the removal trough 22 by means of the gripping arm 55. The removal trough 22 shown in
(49) The gripping jaws 60, 61 of the gripping unit 50 or of the gripping arm 55 can be divided so that they can engage in more than one depression of the removal trough and can grip the cables 15 or the batch at a plurality of points at the same time. The large number of depressions in the removal trough 22 also makes it possible, in the case of batches of longer cables 15, to grasp or hold them over a wide range of lengths or, if necessary, with a plurality of grippers or gripping arms 55.
(50) In the following it is explained by way of example and with the aid of various methods what the handling robot 30 or the gripping unit 50 or the gripping arm 55 can perform or carry out automatically on the crimping system 1 or the crimping device 5.
(51)
(52) One process that can be carried out by means of the handling robot 30 or the gripping arm 55 is a cable replacement, i.e. the replacement of the cable 15 used by the crimping device 5.
(53) A cable replacement is necessary when the cable bundle is empty or an article with a different cable 15 is to be processed. In the first case, a second cable of the same type is prepared in one of the three cable receptacles 111-113 (
(54) The cable 15 to be replaced is introduced or threaded into the cable processing machine 5 as follows:
(55) The cable conveyor device 100 and the alignment unit 115 are opened and the cable gripper 70 of the gripping unit 50 takes over the cable 15 in a program-controlled or computer-controlled manner from the correct gripper or holder of the cable receiving device 110. This is shown in
(56)
(57) The gripping unit 50 is moved so that the cable 15 is inserted into the guide tube 106. Then the cable 15 is clamped in the clamping device 105 so that the cable gripper 70 can grip by being brought into the semi-closed position, being moved away from the guide tube 106 (wherein the cable 15 slides along in the cable gripper 70) and being brought again into the completely closed position so that the cable 15 cannot slide relative to the cable gripper 70.
(58) Afterwards, the clamping device 105 is opened so that the cable 15 is no longer clamped, and the cable 15 is pushed further into the cable conveyor 100 by the gripping unit 50. This is repeated a plurality of times until the cable 15 can be securely grasped by the transport belts 102, 103 when the cable conveyor device 100 is closed. This process is shown in
(59) As soon as the transport belts 102, 103 clamp the cable 15 securely, the cable 15 can be tensioned. For this purpose, the clamping device 105 is closed and the gripping unit 50 moves back until the cable gripper 70 is in front of the alignment unit 115 (see
(60) Afterwards, the alignment unit 115 is closed, so that the actual threading process is completed.
(61) To remove the cable 15, the cable 15 is transported backwards by the cable conveyor device 100 until the transport belts 102, 103 (
(62) A further example of an automated process by means of the handling robot 30 is the replacement of the crimping cassette 80 or the cassette replacement, which is described below.
(63) In a comparable manner to the cable replacement, the crimping cassette 80 must be replaced when the crimping roller inserted in the crimping cassette 80 is empty or when the article to be produced has a different crimp contact. If continuous production is to be possible without manual intervention by the machine operator, the necessary crimping cassettes 80 are to be provided in the crimping cassette receptacle 82 (
(64) Since the gripping unit 50 can be moved to both crimping presses 8, one crimping cassette receptacle 82 or crimping cassette holder on one side of the crimping device 5 is sufficient to supply both crimping presses 8 or to replace the crimping cassette 80 in both crimping presses 8. If a large number of crimping cassettes 80 are provided, the crimping cassette receptacle 82 can be designed in such a way that the crimping cassettes 80 are actively brought from a crimping cassette storage device to a transfer position for transferring the crimping cassette 80 to the gripping arm 55.
(65)
(66) In the simplest case, as shown in
(67)
(68) The cassette is replaced, if necessary, by placing the old crimping cassette 80 in the crimping cassette receptacle 82 and gripping of the new crimping cassette 80 by the gripping arm 55.
(69) The crimping cassette 80 is then moved to or into the crimping press 8 and gripped or clamped there. The crimping cassette 80 has a base plate 85 (
(70) The state after this step is shown in
(71)
(72) A further example of an automated process by means of the handling robot 30 is the checking of processed cables 15 or cable samples, which is described below.
(73) The cables 15 can be brought to quality control devices by means of the gripping unit 50. These can be taken over directly by the gripping unit 50 from the pivoted-out pivot unit 10 of the cable processing machine 5 or crimping machine or crimping device 5. In
(74) The handling robot 30 then brings the cable 15 to the quality control device 90 or to an inspection station.
(75)
(76) A further example of an automated process by means of the handling robot 30 is the removal of defectively produced cables 15 (so-called faulty cables) from the crimping device 5, which is described below.
(77) The defectively produced cables 15 can be removed from the machine most easily if both ends of the cable 15 can be gripped. In order to make this possible, the storage gripper can be used, which is already present in some machines in order to facilitate the cable storage in the cable tray 20.
(78) The faulty cable or defective cable 15 is first transferred from the pivot unit 10 of the crimping device 5 to the storage gripper, which grasps it at the trailing end of the cable 15. The leading end of the cable 15 is already in the cable tray 20 and should be removed again therefrom. For this purpose, the cable gripper 70 of the gripping unit 50 grabs the faulty cable immediately behind the storage gripper and moves with reduced gripper pressure (semi-closed position) in the direction of the leading cable end, the cable 15 sliding in the cable gripper 70.
(79) The trailing cable end is then transferred to the pivot unit again 10. This is shown in
(80) The pivot unit 10 is then pivoted out completely and the gripping unit 50 is rotated and moved until both cable ends are parallel and located outside the cable tray 20. This is shown in
(81)
(82) A further example of an automated process by means of the handling robot 30 is the removal of production batches or processed cables 15 from the removal trough 22, as described below.
(83) When the desired number of cables 15 for a production batch is reached in the cable tray 20, the cable tray 20 is pivoted or tilted so that the batch or the cables 15 fall(s) into the removal trough 22.
(84)
(85) The removal trough 22 is then moved in the longitudinal direction in order to bring it into a region that can be reached by the handling robot 30 and the gripping unit 50 is positioned above the removal trough 22 in such a way that the gripping jaws 60, 61 are above the desired recess or depression in the removal trough 22. This is shown in
(86)
(87) The gripping unit 50 is then lowered (see
(88) If the production batches have been removed from or taken out of the removal trough 22, they can be transferred to a suitable device, such as, for example, transport racks on which the batches or cables 15 are suspended and/or transport containers in which the batches or cables 15 are placed.
(89) The cable processing machine 5 can comprise a further pivot unit in addition to the pivot unit 10 shown in
