Description

Technical Field

[0001] The present application relates to the technical field of terminal processing equipment, and in particular to an automatic terminal crimping device. Background Art

[0002] Terminal crimping equipment is a tool specifically used to tightly connect the conductor at the end of a cable with the terminal. Its main function is to apply pressure to the contact area between the conductor and the terminal at the end of the cable to make them fit tightly together to form a fixed connection.

[0003] During the relevant crimping process, wire strippers are generally used to strip off the insulation layer at the end of the cable to expose the conductor part, and then the stripped cable conductor part is inserted into the conductor clamping part of the terminal. After ensuring that the conductor is fully inserted into place, the terminal inserted into the corresponding matching upper and lower molds of the crimping pliers is placed, and the handle of the crimping pliers is pressed down to apply enough pressure to tightly connect the terminal to the cable conductor.

[0004] With respect to the above-mentioned related technologies, the existing crimping equipment has a low degree of automation and requires a large amount of manual labor to participate in the crimping work, which is labor-intensive and seriously reduces the efficiency of cable terminal crimping, so it needs to be improved.

The transfer cylinder 64 is located on the side of the lower mold 12 away from the transport member 61, and the output end of the transfer cylinder 64 faces the transport member 61. The lifting cylinder 63 is fixedly connected to the output end of the transfer cylinder 64, and the output end of the lifting cylinder 63 faces the upper surface of the workbench 1. The transfer plate 62 is fixedly connected to the output end of the lifting cylinder 63, so that the lifting cylinder 63 can adjust the distance between the transfer plate 62 and the workbench 1, thereby facilitating the push and transfer of the lifted cable body 101 and terminal body 102.

[0056] The implementation principle of the terminal automatic crimping device in the embodiment of the present application is as follows: The terminal body 102 is sleeved on the positioning rod 22, and the output end of the loading cylinder 23 is extended, driving the loading platform 21 to drive the terminal body 102 gradually close to the lower mold 12; in this process, the traction force of the power rope 253 on the pressing plate 24 is gradually reduced, so that the pressing plate 24 gradually presses and fixes the terminal body 102 on the loading platform 21 stably under the torsion of the torsion piece 252.

[0057] The cable body 101 is placed in the placement groove 331, and the output end of the positioning cylinder 353 is controlled to extend so that the positioning plate 352 cooperates with the docking groove 3521 to firmly press the cable body 101 into the placement groove 331. The output end of the rotary motor 34 drives the rotary table 33 to rotate and face the peeling knife 44.

[0058] The output end of the peeling cylinder extends out, causing the peeling knife 44 to push the sliding platform 362 to gradually move into the sliding groove 332, and causing the support platform 361 to gradually fall back into the storage groove 3621. Then, the end of the cable body 101 that is separated from the support platform 361 is pressed between the two sets of peeling knives 44.

[0059] The output end of the clamping cylinder 43 controls the two groups of peeling knives 44 to approach each other and cut the skin at the end of the cable body 101; then, the output end of the peeling cylinder drives the peeling knife 44 to gradually move away from the rotating table 33, so that the peeling knife 44 drives the skin at the end of the cable body 101 to gradually separate from the cable body 101 and fall into the collection box 41.

[0060] Then, the output end of the rotary motor 34 drives the rotary table 33 to rotate and move toward the lower mold 12. The output end of the feeding cylinder 32 extends, so that the rotary table 33 and the support table 361 drive the peeled cable body 101 to gradually approach the lower mold 12. The end of the sliding table 362 away from the rotary table 33 abuts against the lower mold 12, driving the sliding table 362 to drive the support table 361 to move horizontally away from the lower mold 12. Then, the support table 361 gradually retracts into the receiving groove 3621 under the interference of the abutting inclined surface 3612 and the receiving inclined surface 333, so that the support table 361 and the sliding table 362 are received together in the sliding groove 332. In addition, in this process, the conductor of the cable body 101 with the peeled end gradually abuts into the terminal body 102.

[0061] The output end of the crimping part 14 drives the upper mold 13 to press down and close the mold with the lower mold 12 to press the conductor at the end of the cable body 101 and the terminal body 102. The overall pressing process reduces the number of manual assistance steps, thereby improving the degree of automation and work efficiency of the crimping equipment.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
