[0017] Connectors of different specifications and models correspond to terminals of different sizes. Since the material of the terminals is relatively soft, it is necessary to control the size of the wire clamp assembly when it is closed to adapt to the size of the terminals and reduce the deformation of the terminals. However, the existing terminal clamp assembly can only clamp terminals of a single specification and cannot meet the production needs of multiple products. In the terminal clamp assembly of the present technology, the sliding shaft can slide in the sliding groove, and the first movable end of the first linear drive device drives the second half clamp to swing along the first rotation axis through the sliding shaft, so that the left half groove in the second half clamp can move away from or close to the right half groove, and at the same time, the first movable end can drive the second half clamp and the lifting block to move up and down; when the first movable end moves downward, the lifting block and the second half clamp move downward, the lifting block abuts against the lower limit block, the lifting block stops moving, and the first movable end continues to move downward, causing the second half clamp to rotate, the left half groove moves away from the right half groove, and the terminal can enter between the left half groove and the right half groove; when the first movable end moves upward, it drives the second half clamp and the lifting block to move downward. The half clamp rotates, and the left half groove approaches the right half groove, limiting the terminal between the left wall and the right wall, then the second half clamp and the lifting block continue to move upward, the lower side wall pushes the terminal to move to the upper side wall, then the lifting block rises until it abuts against the upper limit block, the second half clamp stops moving, and the first half clamp and the second half clamp clamp the terminal between the upper side wall and the lower side wall; the limiting movable end of the limiting device can move up and down, so that the upper and lower positions of the upper limit block can be adjusted, thereby adjusting the rising height of the lifting block and the second half clamp, and adjusting the distance between the lower side wall and the upper side wall, to adapt to clamping terminals of different sizes, thereby adapting to the production of connectors of various specifications.

[0018] This technology can adapt to the production of wire harnesses of different specifications and models by providing a terminal crimping mechanism that can crimp terminals of different specifications, a connector switching feeding module that can switch between different connector feedings, and a terminal clamp assembly that can adjust and clamp terminals of different specifications.

[0023] The driving motor drives the driving screw to rotate, and the driving nut moves horizontally in the left and right directions. The block on the driving nut is slidably connected with the guide groove on the sliding block. Since the upper limit block and the driving screw are relatively fixed in the left and right directions, the left and right movement of the driving nut drives the upper limit block to move up and down, so that the height of the upper limit block can be adjusted, and the product can be switched conveniently. In addition, the driving screw is set in the left and right directions, and the upper limit block moves up and down.

[0069] The upper wire cutting and peeling mechanism 201 is used for feeding the wire, cutting the wire and removing the rubber from the end of the wire; the terminal crimping module includes at least two terminal crimping mechanisms 301, and the terminal crimping mechanism 301 is used to crimp the metal terminal on the end of the wire from which the rubber has been removed. Different terminal crimping mechanisms 301 can crimp metal terminals of different sizes; the connector switching feeding module 501 is used for feeding the connector, and can switch connectors of different specifications; the connector is fed from the connector switching feeding module 501 to the connector clamp assembly 701; the wire transport clamp assembly in the wire transport module 601 can clamp the wire and transport it from the upper wire cutting and peeling mechanism 201 to the terminal crimping mechanism 301 and the wire plugging mechanism 401; the second wire clamp assembly 402 in the wire plugging mechanism 401 clamps the wire from the wire transport clamp assembly, and the terminal clamp assembly 403 clamps the terminal part to position it, and then inserts it into the connector jack.

[0070] Connectors of different specifications and models correspond to terminals of different sizes. Since the material of the terminals is relatively soft, it is necessary to control the size of the wire clamp assembly when closed to adapt to the size of the terminals and reduce the deformation of the terminals. The existing terminal clamp assembly 403 can only clamp terminals of a single specification and cannot meet the production needs of multiple products. In the terminal clamp assembly 403 of the present technology, the sliding shaft 4104 can slide in the sliding groove 4304, and the first movable end of the first linear drive device 4102 drives the second half clamp 4302 to swing along the first rotation axis 4303 through the sliding shaft 4104, so that the left half groove 4305 in the second half clamp 4302 can move away from or close to the right half groove 4202, and at the same time, the first movable end can drive the second half clamp 4302 and the lifting block 4301 to move up and down; when the first movable end moves downward, the lifting block 4301 and the second half clamp 4302 move downward, the lifting block 4301 abuts against the lower limit block 4105, the lifting block 4301 stops moving, and the first movable end continues to move downward, so that the second half clamp 4302 rotates, the left half groove 4305 moves away from the right half groove 4202, and the terminal can enter between the left half groove 4305 and the right half groove 4202; when When the first movable end moves upward, it drives the second half clamp 4302 to rotate, and the left half groove 4305 approaches the right half groove 4202, limiting the terminal between the left wall and the right wall, and then the second half clamp 4302 and the lifting block 4301 continue to move upward, and the lower side wall pushes the terminal to move toward the upper side wall, and then the lifting block 4301 rises to abut against the upper limit block 4402, and the second half clamp 4302 stops moving, and the first half clamp 4201 and the second half clamp 4302 clamp the terminal between the upper side wall and the lower side wall; the limiting movable end of the limiting device 4401 can move up and down, so that the upper and lower positions of the upper limit block 4402 can be adjusted, thereby adjusting the rising height of the lifting block 4301 and the second half clamp 4302, and adjusting the distance between the lower side wall and the upper side wall, so as to adapt to clamping terminals of different sizes and specifications, thereby adapting to the production of connectors of various specifications.

[0071] This technology can adapt to the production of wire harnesses of different specifications and models by providing a terminal crimping mechanism 301 that can crimp terminals of different specifications, a connector switching feeding module 501 that can switch between different connector feedings, and a terminal clamp assembly 403 that can adjust and clamp terminals of different specifications.

[0072] In some specific embodiments of the present invention, the limiting device 4401 includes:

[0073] A driving screw 4403 is rotatably connected to the vertical plate 4101. The driving screw 4403 is arranged along the left-right direction, and the limit fixing end includes the driving screw 4403;

[0075] The driving nut 4405 is threadedly connected to the driving screw 4403, and the upper limit block 4402 is connected to the lower side of the driving nut 4405. A clamping block is provided on the lower side of the driving nut 4405, and a guide groove 4406 is provided on the upper side of the upper limit block 4402.

[0076] The driving motor 4404 drives the driving screw 4403 to rotate, and the driving nut 4405 moves horizontally in the left-right direction. The block on the driving nut 4405 is slidably connected with the guide groove 4406 on the sliding block. Since the upper limit block 4402 and the driving screw 4403 are relatively fixed in the left-right direction, the left-right movement of the driving nut 4405 drives the upper limit block 4402 to move up and down, so that the height of the upper limit block 4402 can be adjusted, and the product can be switched conveniently. In addition, the driving screw 4403 is set in the left-right direction, while the upper limit block 4402 moves up and down. When the upper limit block 4402 and the driving nut 4405 are subjected to the upward force of the lifting block 4301, they cannot drive the driving screw 4403 to rotate, and can stably maintain the position of the upper limit block 4402, thereby improving the stability of the clamping terminal.

In addition, the position sensor 4407 can also play a role in determining the origin position of the upper limit block 4402. The position sensor 4407 can be set as a photoelectric sensor, a laser sensor, etc., and the position sensing part 4408 can be set as a sensing sheet or a notch, etc.

The transmission is carried out through the first synchronous wheel 4409, the second synchronous wheel 4410 and the synchronous belt 4411, and the structure is simple and the weight is light. The drive motor 4404 can also be transmitted to the drive screw 4403 through a transmission structure such as a coupling and a gear.

[0079] In some specific embodiments of the present invention, a fixed block 4501 is fixedly connected to the vertical plate 4101, and the fixed block 4501 is arranged on the upper side of the lifting block 4301, and a compression spring 4502 is arranged between the fixed block 4501 and the lifting block 4301. Since the sliding groove 4304 is arranged on the second half clamp 4302 and connected to the sliding shaft 4104, the lifting block 4301 may also slide up and down and the second half clamp 4302 may shake and rotate easily, and the compression spring 4502 may exert a force on the lifting block 4301 to keep the lifting block 4301 relatively stable, so that when the terminal is clamped, the second half clamp 4302 is rotated first and then lifted, and the shaking of the lifting block 4301 and the second half clamp 4302 after the movement is reduced, thereby improving the clamping stability.
