[0022] 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.

[0023] Example: Reference Figure 1-2 A novel wiring harness terminal machine shown in the figure includes an E-tube terminal machine 2 and a chain plate conveyor 1. Each chain plate of the chain plate conveyor 1 is provided with a bearing plate 5 for carrying and fixing the wiring harness. An elastic buckle 8 is fixed to the upper end of the bearing plate 5, and the elastic buckle 8 has an inverted eight-shaped opening and a fixing cavity adapted to the wiring harness. The E-tube terminal machine 2 is arranged in two groups, and the two E-tube terminal machines 2 are arranged opposite to each other and have balls at the bottom. The feed ports of the two E-tube terminal machines 2 are respectively located at the two ends of the same bearing plate 5;

[0024] It also includes a driving unit 3 for driving the two E-type terminal machines 2 to move relative to or backwards, and the driving unit 3 includes two mounting seats 31 respectively located below the corresponding E-type terminal machines 2, and the two mounting seats 31 are fixedly connected to the chain plate conveyor 1. The two mounting seats 31 are rotatably provided with a threaded rod 32 that penetrates the chain plate conveyor 1, and the two ends of the threaded rod 32 are respectively provided with a forward thread segment and a reverse thread segment, and nuts 33 are threadedly sleeved on the forward thread segment and the reverse thread segment. The upper ends of the two nuts 33 are fixedly connected to the lower end of the E-type terminal machine 2 through a connecting plate 34, and the two mounting seats 31 are provided with a movable opening adapted to the connecting plate 34, and one end of the threaded rod 32 is connected to the output shaft of a motor 35 installed at the side end of the mounting seat 31;

[0025] The two E-tube terminal machines 2 , the motor 35 and the chain plate conveyor 1 are all electrically connected to a PLC controller 4 installed on the chain plate conveyor 1 .

[0026] 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 8, so that both ends of the wire harness exceed a part of both sides of the chain plate conveyor 1. 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 motor 35 works to drive the threaded rod 32 to rotate forward. Driven by the two nuts 33, the two E-type terminal machines move relative to each other and the two ends of the wire harness are respectively inserted into the corresponding E-type terminal machine feed port at the same time (at this time The motor 35 stops working) and performs stripping and crimping operations. After the processing is completed, the motor 35 rotates in the reverse direction to restore the two E-tube terminal machines 2 to their original positions. After completion, the chain plate conveyor 1 starts running again to transport the next wire harness to the processing position for processing. The operator removes the processed wire harness at the loading end and replaces it with an 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 can process both ends of the wire harness at the same time, which can greatly improve the wire harness processing efficiency.

[0027] It should be noted that, first, when the chain conveyor 1 stops running, during this period, the operator can install the wire harness on the supporting plate 5; second, a limiting groove 7 adapted to the wire harness is provided on the supporting plate 5, which can limit the wire harness on the supporting plate 5 to prevent the two ends of the wire harness from moving due to the vibration generated during the operation of the chain 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; third, the width of the chain conveyor 1 is smaller than the length of the wire harness, so that both ends of the wire harness can extend beyond a part of the side end of the chain conveyor 1.

[0028] As a preferred implementation in this embodiment, Figure 3As shown, it also includes an automatic unloading unit 6, which automatically removes the wire harness from the carrier plate 5 after stripping and terminal crimping.

[0029] The automatic unloading unit 6 automatically unloads the wire harness after crimping, which can reduce the labor intensity of operators and further improve the efficiency of wire harness processing.

[0030] As a preferred implementation in this embodiment, Figure 3-5 As shown, the automatic unloading unit 6 includes a unloading trough 63 arranged on the supporting plate 5 and an L-shaped rod 61 installed on the supporting frame of the chain plate conveyor 1. The unloading trough 63 is arranged close to the elastic buckle 8. 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 cross bar end of the L-shaped rod 61 is smaller than the size of the unloading trough 63.

[0031] 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.

[0032] 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 8, the L-shaped rod 61 and the wire harness are squeezed and it is difficult to separate the wire harness from the elastic buckle 8. The closer it is, the more conducive it is to the feeding of the wire harness.

[0033] As a preferred implementation in this embodiment, Figure 4 and 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 8 and arranged close to the elastic buckle 8 , and the L-shaped rod 61 is arranged in two groups at intervals and arranged corresponding to the two groups of feed troughs 63 .

[0034] The feed trough 63 is arranged in two groups, which are respectively located on both sides of the elastic buckle 8, 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 8 can be subjected to downward force, which is more conducive to the separation of the wire harnesses from the elastic buckle.

[0035] As a preferred implementation in this embodiment, Figure 4 As shown, the inclination angle of the blanking slope 62 is set to be no higher than 30°.

[0036] 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 8 to produce 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 8, which may easily cause the wire harness and the elastic buckle 56 to form a strong extrusion and produce scratches (affecting the appearance of the wire harness).

[0037] 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.
