Specific embodiments

[0022] For the convenience of those skilled in the art to understand the present technical solution more clearly, the following will combine with the attached Figures 1-5 elaborate on the technical solution of the present utility model in detail:

[0023] A cam pin insertion mechanism includes an installation mechanism 1, a cam feeding mechanism 2 arranged on the installation mechanism 1, a terminal conveying mechanism 3 arranged on one side of the cam feeding mechanism 2, and a cutting mechanism 4 arranged on the installation mechanism 1 and on one side of the terminal conveying mechanism 3. The cam feeding mechanism 2 is fixedly installed on the installation mechanism 1, and the terminal conveying mechanism 3 is connected to the cam feeding mechanism 2. During operation, the installation mechanism 1 can support the cam feeding mechanism 2, the terminal conveying mechanism 3, and the cutting mechanism 4, and can also be installed on the machine table according to the use requirements. The terminal conveying mechanism 3 can complete the feeding of terminals, and the cam feeding mechanism 2 can feed the terminals on the terminal conveying mechanism 3 to the position of the cutting mechanism 4, facilitating the cutting operation of the cutting mechanism 4 on the terminals, and after the cutting mechanism 4 cuts, it can send out the cut terminals for plugging operation with other parts.

[0024] Among them, the installation mechanism 1 includes a support frame 11 and a first transverse movement mechanism 12 arranged on the support frame 11. The first transverse movement mechanism 12 is installed on the support frame 11, and the cam feeding mechanism 2 is arranged on the first transverse movement mechanism 12. During operation, the first transverse movement mechanism 12 can be adjusted according to the use requirements, so that the cam feeding mechanism 2, the terminal conveying mechanism 3, and the cutting mechanism 4 move, facilitating the better completion of the terminal processing operation.

[0025] Among them, a limit plate 13 is further provided on the terminal conveying mechanism 3. The limit plate 13 is fixedly installed on the terminal conveying mechanism 3. A positioning groove is provided on the limit plate 13. The limit plate 13 can limit the terminals to prevent them from moving around when moving on the terminal conveying mechanism 3.

[0026] Next, the structure of the cam feeding mechanism 2 will be elaborated in detail. The cam feeding mechanism 2 includes a fixed frame 21 arranged on the first lateral moving mechanism 12, a control motor 22 arranged on the fixed frame 21, a cam mechanism 23 connected to the control motor 22, a gear mechanism 24 connected to the cam mechanism 23, a bevel gear mechanism 25 meshed and connected to the gear mechanism 24, a feeding cam 26 connected to the bevel gear mechanism 25, a feeding track 27 connected to the feeding cam 26, and a feeding needle mechanism 28 arranged on the feeding track 27. The fixed frame 21 is fixedly installed on the first lateral moving mechanism 12, the control motor 22 is fixedly installed on the fixed frame 21, the feeding track 27 is arranged in parallel with the terminal feeding mechanism, and the feeding needle mechanism 28 is arranged above the terminal feeding mechanism. During operation, the control motor 22 can control the rotation of the cam mechanism 23. The rotation of the cam mechanism 23 can cause the gear mechanism 24 to rotate. The rotation of the gear mechanism 24 can drive the bevel gear mechanism 25 to rotate. The rotation of the bevel gear mechanism 25 can drive the feeding cam 26 to rotate. Due to the design of the feeding track 27, it can cause the feeding track 27 and the feeding needle mechanism 28 to move laterally, thereby completing the feeding operation of the terminals. The feeding needle mechanism 28 can limit the terminals.

[0027] Among them, the cutting mechanism 4 is connected to the cam mechanism 23 through a swing rod 5. One end of the swing rod 5 is rotatably installed on the cam mechanism 23, and the other end of the swing rod 5 is connected to the cutting mechanism 4. When the cam mechanism 23 works, it can drive the swing rod 5 to rotate, and then can cause the cutting mechanism 4 to move longitudinally, so as to drive the cut terminals to complete the feeding operation and complete the pin insertion operation with other parts.

[0028] Among them, an installation plate 6 is further provided on one side of the cutting mechanism 4 close to the fixed frame 21. Moving sliders 7 are provided at the upper and lower ends on one side of the installation plate 6 close to the fixed frame 21. Moving slide rails 8 are provided on the fixed frame 21 corresponding to the positions of the moving sliders 7. The moving sliders 7 are slidably installed on the moving slide rails 8. The design of the installation plate 6, the moving sliders 7, and the moving slide rails 8 can limit the longitudinal movement of the cutting mechanism 4, making the feeding operation convenient.

[0029] Among them, a return spring 9 is provided at one end of the installation plate 6. The other end of the return spring 9 is fixedly connected to the fixed frame 21. The return spring 9 can limit the movement of the installation plate 6 and the cutting mechanism 4 to prevent them from moving around without reason, and it is convenient to return after processing.

[0030] The structure of the cutting mechanism 4 will be elaborated in detail below. The cutting mechanism 4 includes a control cylinder 41, a mounting block 42 connected to the control cylinder 41, a lower cutting knife 43 connected to the mounting block 42, a collet base 44 disposed on the mounting plate 6 and located below the lower cutting knife 43, and a positioning post 45 disposed on the lower cutting knife 43. The control cylinder 41 is fixedly mounted on the mounting plate 6. The collet base 44 is fixedly mounted on the moving plate. The positioning post 45 is fixedly mounted at the central position of the lower cutting knife 43. During operation, the wiring terminal is conveyed to the collet base 44, and then the control cylinder 41 is operated to control the lower cutting knife 43 to complete the cutting operation on the wiring terminal. And during operation, the wiring terminal is positioned by the positioning post 45, which facilitates the lower cutting knife 43 to better complete the cutting operation. Further, the positioning post 45 positions the cut wiring terminal, and the cutting mechanism 4 moves longitudinally to complete the pin insertion operation. After the pin insertion is completed, the control cylinder 41 resets, and the cutting mechanism 4 resets.
