[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1-3 A high-efficiency terminal machine for wire harness production shown in the figure comprises an E-tube terminal machine 2, a chain plate conveyor 1 and two power parts 3, each chain plate of the chain plate conveyor 1 is provided with a bearing unit 5 for bearing and fixing the wire harness, the E-tube terminal machine 2 is arranged in two groups, the two E-tube terminal machines 2 are arranged opposite to each other, and the feed ports of the two E-tube terminal machines 2 are respectively aligned with the ends of the corresponding bearing units 5, and the two bearing units 5 respectively aligned with the two feed ports are arranged adjacent to each other;

[0025] The load-bearing unit 5 includes a mounting block 51 with a groove 52 and fixedly mounted on the chain plate. A slide plate 54 is slidably arranged on the mounting block 51 through a T-shaped block 53. The lower end of the slide plate 54 is fixedly connected to one end of a return spring 55. The return spring 55 is located in the inner cavity of the groove 52, and the other end of the return spring 55 is fixedly connected to the inner wall of the groove 52. An elastic buckle 56 is fixed to the upper end of the slide plate 54, and the elastic buckle 56 has an inverted eight-shaped inlet opening and a fixed cavity adapted to the wiring harness.

[0026] Two power members 3 are fixed on the chain plate conveyor 1 in a left and right manner, and are respectively arranged corresponding to the corresponding feed ports of the E-tube terminal machine 2, and the output end of the power member 3 is facing the side end of the slide plate 54;

[0027] The two E-tube terminal machines 2 , the two power members 3 and the chain plate conveyor 1 are all electrically connected to a PLC controller 4 installed on the chain plate conveyor 1 .

[0028] When in use, the chain plate conveyor 1 is controlled to work, and the middle part of the wire harness is manually inserted into the fixed cavity of the elastic buckle 56, so that both ends of the wire harness exceed a part of the end of the slide plate 54, and the exceeding part is the stripping and crimping part. When the wire harness moves to the processing position, the chain plate conveyor 1 stops working. At this time, the two power members 3 work, and their output ends push the two adjacent slide plates 54 to do opposite movements (the return spring 55 is compressed during this process), and the ends of the wire harness thereon are inserted into the feed port of the E-tube terminal machine 2 (the left or right end of the wire harness is crimped). Stripping and crimping operation), after the stripping and crimping is completed, the power part 3 returns to its original position and returns to its original position under the action of the reset spring 55. At this time, the chain plate conveyor 1 works and continues to transport the wire harness to the processing station for stripping and crimping operation. After the processing is completed, the operator removes the processed wire harness at the feeding end and replaces it with the unprocessed wire harness. The terminal machine does not need to manually flip the wire harness and insert its two ends into the feed port of the E-tube terminal machine for processing, and the left and right ends of adjacent wire harnesses can be processed at the same time, which can greatly improve the wire harness processing efficiency.

[0029] It should be noted that, first, the power part 3 can be an electric telescopic rod or a cylinder; second, when the chain plate conveyor 1 stops running, during this period, the operator can install the wire harness on the carrying unit 5; third, a limiting groove 7 adapted to the wire harness is provided on the slide plate 54, which can limit the wire harness on the slide plate 54 to prevent the two ends of the wire harness from moving due to the vibration generated during the operation of the chain plate conveyor 1, thereby affecting the accuracy of the subsequent insertion of the wire harness end into the feed port of the E-tube terminal machine.

[0030] As a preferred implementation in this embodiment, Figure 4 As shown, it also includes an automatic unloading unit 6, which automatically removes the wire harness from the carrying unit 5 after stripping and terminal crimping.

[0031] The automatic unloading unit 6 automatically unloads the wire harness after crimping, which can reduce the labor intensity of operators and further improve the processing efficiency of the wire harness.

[0032] As a preferred implementation in this embodiment, Figure 4 and 5As shown, the automatic unloading unit 6 includes a unloading trough 63 arranged on the slide plate 54 and an L-shaped rod 61 installed on the support frame of the chain plate conveyor 1. The unloading trough 63 is arranged close to the elastic buckle 56. A unloading slope 62 is arranged at the bottom of the cross bar of the L-shaped rod 61. The L-shaped rod 61 is arranged corresponding to the unloading trough 63, and the end of the cross bar of the L-shaped rod 61 is smaller than the size of the unloading trough 63.

[0033] When the chain plate conveyor 1 is running, the cross bar end of its L-shaped rod 61 will be inserted into the discharge trough 63. As the chain plate conveyor 1 continues to run, the upper end of the wire harness will contact and be squeezed with the discharge slope 62 of the L-shaped rod 61. At this time, the wire harness is subjected to a downward force, and finally the wire harness moves out of the fixed cavity and moves downward to the receiving bucket placed below, thereby realizing automatic discharge operation.

[0034] It should be noted that the feed chute 63 needs to be set close to the elastic buckle 56, which is conducive to the L-shaped rod 61 to squeeze the wire harness and send it to the receiving bucket below. When the feed chute 63 is set away from the elastic buckle 56, the L-shaped rod 61 and the wire harness are squeezed and it is difficult to separate the wire harness from the elastic buckle 56. The closer it is, the more conducive it is to the feeding of the wire harness.

[0035] As a preferred implementation in this embodiment, Figure 5 As shown, the feed trough 63 is arranged in two groups, and the two groups of feed troughs 63 are respectively located on both sides of the elastic buckle 56 and arranged close to the elastic buckle 56 , and the L-shaped rod 61 is arranged in two groups at intervals and arranged corresponding to the two groups of feed troughs 63 .

[0036] The feed trough 63 is arranged in two groups, which are respectively located on both sides of the elastic buckle 56, and the corresponding L-shaped rod 61 is also arranged in two groups, so that the wire harnesses located on both sides of the elastic buckle 56 can be subjected to downward force, which is more conducive to the separation of the wire harnesses and the elastic buckle.

[0037] As a preferred implementation in this embodiment, Figure 5 As shown, the inclination angle of the blanking slope 62 is set to be no higher than 30°.

[0038] When the inclination angle is too large, after the wire harness contacts the cutting slope 62, the wire harness will be easily subjected to a large lateral force, which may cause the elastic buckle 56 to generate a large lateral force 1 and cause irreversible deformation (the irreversible deformation may easily affect the fixing effect of the wire harness), and increase the lateral friction between the wire harness and the elastic buckle 56, which may easily cause strong extrusion between the wire harness and the elastic buckle 56 and produce scratches (affecting the appearance of the wire harness).

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
