[0002] Terminal crimping machines are essential tools for the power industry to continuously crimp wires during line infrastructure construction and line maintenance. They are used to perform fast, accurate and consistent crimping operations on terminals. Fully automatic terminal crimping machines are widely used in electronics manufacturing, electrical equipment manufacturing, automotive industry and other fields. They are suitable for crimping wires, cables and terminals, and they can ensure product quality and consistency.

[0003] After searching, the Chinese utility patent with publication number CN220341653U discloses a fully automatic terminal crimping machine, including a workbench, the left side of which is fixedly connected to two fixed plates, the middle parts of the two fixed plates are rotatably connected to connecting rods, the rear side of one of the fixed plates is fixedly connected to a servo motor, one end of the connecting rod is fixedly connected to the output end of the connecting rod, the outer periphery of the connecting rod is fixedly connected to a winding roller, the outer periphery of the winding roller is sleeved with a terminal belt, the other end of the terminal belt is slidably connected to the middle part of the workbench, and the left side of the workbench is fixedly connected to a fixed block. In this utility model, through the cooperation of chain conveyor, fixed block, partition, pulley and other structures, the gears can put the wires and cables into the card plate one by one for crimping, thereby reducing manual operation, and the crimping machine can quickly put the wires and cables into the middle of the card plate for crimping through the gears, thereby improving production efficiency.

[0004] The crimping machine needs to align the crimping end of the wire and cable with the terminal strip before crimping can be performed. Therefore, the prerequisite is that the length of the wire and cable is just stuck in the card plate on the chain conveyor, so that the two ends of the wire and cable are aligned with the inner wall of the workbench respectively, so that the crimping end of the wire and cable can fall onto the terminal strip, and the telescopic hydraulic cylinder drives the pressure block to crimp the wire and cable. The crimping machine cannot perform terminal crimping on wire harnesses of various lengths and sizes, and its practicality is low. Utility Model Content

[0025] 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.

[0026] See also Figure 1-4 , including a crimping machine housing 1 and a chain conveyor 3 installed inside the crimping machine housing 1, a movable plate 8, which is hingedly connected to the crimping machine housing 1 through an installation groove opened on the top of the crimping machine housing 1; a connecting plate 9, which is fixed at the bottom of the movable plate 8 and is divided into three groups with equal spacing; a positioning roller 10, which is movably assembled with the connecting plate 9 through a rotating shaft, and the three groups of positioning rollers 10 are connected by transmission belts, and the transmission shaft of one group of positioning rollers 10 is extended. In addition to the transmission belts for mutual transmission between the positioning rollers 10, the surface of the movable shaft is also connected with a second transmission belt. A through hole is opened on the surface of the movable plate 8 at a position corresponding to the second transmission belt, and a motor is installed on the side of the through hole, which is connected to the transmission belt through the output end of the motor, so that when the motor drives the transmission belt to move, each group of positioning rollers 10 rotates with the transmission belt. When the positioning roller 10 rotates, the bristles at the bottom of the positioning roller 10 contact the wiring harness transmitted on the surface of the chain conveyor 3, and the rotation of the positioning roller 10 drives the bristles to push the wiring harness to move, so that The wire harness moves to one side of the inner wall of the crimping machine housing 1, and the end of the wire harness is aligned with the inner wall of the crimping machine housing 1. When the end of the wire harness abuts against the inner wall of the crimping machine housing 1, the wire harness can no longer be pushed by the positioning roller 10; the support platform 11 is fixed to one side of the inner wall of the crimping machine housing 1 and is at the same horizontal height as the surface of the chain conveyor 3. When the positioning roller 10 pushes the wire harness to move, the end of the wire harness that needs to be crimped falls on the surface of the support platform 11; the pressing wheel 12 is installed on the side of the positioning roller 10 and is located Above the chain conveyor 3, a rubber strip is provided on the surface of the pressure wheel 12. When the positioning roller 10 pushes the wire harness to the side of the inner wall of the crimping machine housing 1, it needs to continue to be conveyed through the chain conveyor 3. During the transmission process, the wire harness may be offset. The rubber strip on the surface of the pressure wheel 12 is aligned with the wire harness so that the pressure wheel 12 and the chain conveyor 3 rotate synchronously. At this time, the wire harness can be clamped and fixed by the pressure wheel 12 and the chain conveyor 3 to limit the movement of the wire harness position and ensure the accuracy of crimping.

[0027] A feeding port 2 is provided at the top of one end of the crimping machine housing 1. A hydraulic cylinder 4 is designed on the side of the crimping machine housing 1 away from the feeding port 2, and the hydraulic cylinder 4 and the support platform 11 are located on the same side. The telescopic end of the hydraulic cylinder 4 fixes the pressing block. When the chain conveyor 3 transports the wire harness to the bottom of the pressing block, the end of the wire harness is crimped by the telescopic hydraulic cylinder 4. During the crimping process, the pressing wheel 12 still fixes the position of the wire harness to avoid the wire harness from being offset during the crimping process, thereby ensuring the quality of the finished product of the wire harness crimping.

[0028] A feeding roller 5 is installed on the side of the positioning roller 10 away from the pressing wheel 12, and the transmission shaft of the feeding roller 5 is connected to the transmission shaft of the chain conveyor 3 through a transmission belt.

[0029] A rotating shaft is fixed on the side of the discharge port 2 away from the support platform 11, and a guide plate 6 is fixed on the side of the rotating shaft close to the discharge roller 5. A movable groove is provided at the bottom of the discharge port 2 close to the guide plate 6, and a bolt 7 is installed in the movable groove. When a shorter wire harness needs to be crimped, the guide plate 6 can be rotated to reduce the opening of the guide plate 6 close to the discharge roller 5, so that the wire harness falls onto the surface of the chain conveyor 3 after being arranged. The wire harness arranged by the guide plate 6 can be closer to the inner wall of the crimping machine housing 1, which is convenient for the subsequent movement and positioning of the positioning roller 10.

[0030] Working principle: according to the length of the wire harness to be processed, the guide plate 6 is rotated to reduce the width of the opening of the guide plate 6 close to the discharge roller 5, and the wire harness is placed in the discharge port 2, so that the wire harness passes through the discharge port 2 and slides onto the surface of the chain plate conveyor 3. After the wire harness falls onto the surface of the chain plate conveyor 3, it moves to the bottom of the positioning roller 10 through the chain plate conveyor 3. Through the continuous push of the three groups of positioning rollers 10, the compressed end of the wire harness moves to the surface of the positioning roller 10, and the end contacts the inner wall of the crimping machine housing 1 to realize the positioning of the wire harness. When the crimping end of the wire harness is positioned, the chain plate conveyor 3 moves the wire harness to the bottom of the pressing wheel 12, and the rubber strip on the surface of the pressing wheel 12 presses the wire harness between the pressing wheel 12 and the chain plate conveyor 3 to prevent the wire harness from moving. When the wire harness is transported to the bottom of the hydraulic cylinder 4, the pressing block at the telescopic end of the hydraulic cylinder 4 completes the crimping task on the end of the wire harness. In the process of crimping the wire harness, the wire harness is still restricted by the pressing wheel 12 and the chain plate conveyor 3 to prevent the wire harness from sliding during crimping, thereby improving the yield rate of crimping of the wire harness. The crimped wire harness is continued to be moved by the chain plate conveyor 3 until it falls into the collection box set at the bottom of the chain plate conveyor 3.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
