[0034] Please pay attention to Figure 2 The needle pressing tooling assembly 3 includes a sliding block 31, a front end surface of the sliding block 31 is provided with an adjustment box 32, and a needle pressing box 33 which can be adjusted up and down is provided on the front side of the adjustment box 32. This design can perform needle pressing processing on the board end connector.

[0035] The sliding block 31 is respectively provided with a through groove 311 and a thread groove 312 , the limiting rod 23 passes through the through groove 311 , and the screw rod 22 is engaged inside the thread groove 312 . This design enables the needle pressing tooling assembly 3 to slide left and right.

[0036] The front end face of the regulating box 32 is provided with an inwardly recessed regulating chamber 321, the inner bottom of the regulating chamber 321 is provided with a cushion block 322, the interior of the regulating chamber 321 is provided with a rotatable threaded shaft 323, the lower end portion of the threaded shaft 323 is installed inside the cushion block 322, and the threaded shaft 323 passes through the upper side of the regulating box 32 and is provided with a knob 324 at one end. This design can adjust the upper and lower positions of the needle pressing box 33.

[0037] A connecting block 331 is symmetrically arranged at one end of the needle pressing box 33 close to the regulating chamber 321 , and the symmetrically arranged connecting block 331 is provided with a threaded hole 3311 engaged with the threaded shaft 323 . This design enables the upper end needle pressing box 33 to move up and down.

[0038] The interior of the needle pressing box 33 is respectively provided with a cabin 332 and a needle pressing bin 333, and the lower end of the needle pressing box 33 is provided with a needle outlet 334, and the lower end of the needle outlet 334 is provided with an elastic cone 3341, which can guide the needle out, and the design of the elastic cone 3341 will not cause the needle to fall directly.

[0039] A cylinder 3321 is disposed in the engine room 332, and a pin pressing block 3322 is disposed on the lower end surface of the output shaft of the cylinder 3321. This design can press the pin into the board-end connector.

[0040] The side wall of the needle pressing bin 333 is provided with a spring 3331, and the other end of the spring 3331 is provided with a push block 3332. This design can automatically push the needle to fill the position.

[0041] Please pay attention to Figure 1 , Figure 5 The front wall of the needle pressing box 33 is provided with an adjustment groove 335, and an adjustment knob 3351 is provided in the adjustment groove 335. The end of the adjustment knob 3351 whose axis extends into the needle pressing bin 333 is fixedly connected with the push block 3332. The upper end of the needle pressing box 33 is provided with a needle placing hole 336 connected with the needle pressing bin 333. This design can pull the push block 3332 to the rearmost position, and then add a needle through the needle placing hole 336.

[0042] The specific operation method of the utility model is as follows: when in use, first grasp the adjustment knob 3351 and pull it to the right. As the adjustment knob 3351 is pulled, the push block 3332 will squeeze the spring 3331 until it cannot be pulled. At this time, the pin is put into the pin hole 336. The inserted pin will fall from the pin hole 336 to the inside of the pin pressing bin 333. At this time, loosen the adjustment knob 3351 a little to make the push block 3332 push the pin to the left to prevent the pin from blocking the pin hole 336 and affecting the addition of the next pin. Repeat the above steps until the pin pressing bin 333 is full of pins. After the pins are added;

[0043] Rotate the knob 324 left and right to rotate the threaded shaft 323, and the rotating threaded shaft 323 engages with the threaded hole 3311 of the connecting block 331, so that the needle pressing box 33 moves up and down. Adjust the needle pressing box 33 to a suitable height for use;

[0045] Start the motor 24, and the motor 24 drives the screw rod 22 to rotate. The rotating screw rod 22 engages with the threaded groove 312 of the sliding block 31, so that the adjustment box 32 and the needle pressing box 33 can slide left and right. When sliding to the preset position, the cylinder 3321 is started and the needle pressing block 3322 is pushed downward. The needle pressing block 3322 pushes the pin out of the pin pressing bin 333, so that the pin is pressed into the board-end connector to complete the processing. After a plug is pressed, the cylinder 3321 will drive the needle pressing block 3322 to reset quickly. After the reset, the spring 3331 will push the push block 3332, so that the next pin is filled in for subsequent needle pressing processing. After completing the needle pressing processing of a board-end connector, it is necessary to add the pin to the needle pressing bin 333 in time.

[0046] It should be noted that the motor 24 of the present embodiment is a forward and reverse motor 24.
