The brush needle impact mechanism 7 adopting the scheme can only be positioned above the tail end of the rubber core stamping table 14, the brush needle impact mechanism 7 is not convenient to mount, and the brush needle impact mechanism 7 vibrates during working, so that other rubber cores 10 on the rubber core stamping table 14 move.

when the turning plate 7056 is in the pre-rotation state, the second rail 70561 corresponds to the rubber core slide rail 5031 in a matching manner, and when the turning plate 7056 is in the post-rotation state, the soldering lug connecting belt 121 on the rubber core 10 on the second rail 70561 is in the same height as the position of the first brush pin cylinder 701 after the brush pin lifting cylinder 706 is ventilated.

By installing the turnover mechanism 705, the brush needle impact mechanism 7 can be located at one side of the core rubber stamping platform 14, and the stability of the core rubber stamping platform 14 cannot be affected when the brush needle impact mechanism 7 works.

Of course, for pressing the rubber core 10 on the turning plate 7056 to prevent the rubber core 10 from falling, it is preferable to install a limiting plate 709 on the sliding plate 7057, when the turning plate 7056 is completely moved to the sliding plate 7057, the limiting plate 709 is just above the turning plate 7056, only the soldering lug connection belt 123 on the rubber core 10 of the turning plate 7056 is exposed, and only part of the rubber core 10 is exposed, so as to achieve the purpose of blocking the rubber core 10 to prevent the rubber core 10 from falling out.

11. the retreating cylinder 136 starts to work to drive the retreating seat 137 to retreat, and at the moment, the fixed strip 133 and the moving strip 134 both retreat and separate from the rubber core 10;

12. the second stepping motor 131 starts to rotate to drive the clamping cylinder 132, the fixing strip 133, the moving strip 134, the rubber core clamping moving seat 135, the retreating cylinder 136 and the retreating seat 137 to integrally move leftwards;

13. the retreating cylinder 136 starts to reset to drive the retreating seat 137 to move forward, and at the moment, the fixed strip 133 and the moving strip 134 both move forward;

14. repeating the steps 11 to 13, so that the rubber core 10 moves to the position right below the stamping die 601, the clamping air cylinder 132 starts to work, the moving strip 134 moves towards the fixing strip 133, and the rubber core 10 is clamped under the action of the fixing strip 133 and the moving strip 134;

15. the third stepping motor 603 starts to rotate, the soldering lug connecting belt 121 is moved into the stamping die 601, and the third stepping motor 603 stops rotating after the second sensor senses that the length of the soldering lug connecting belt 121 entering the stamping die 601 is enough;

16. the stamping cylinder 607 starts to work to drive the stamping die 601 to move downwards, so that the soldering lug connecting strip 121 is stamped on the rubber core 10;

17. because the product of the invention continuously works, the steps 11 to 13 are repeated, and the punched rubber core 10 is moved to the second track 70561 of the turning plate 7056;

18. the second straight stroke cylinder 708 starts to work to drive the square bar 7081 to move towards the sliding plate 7057, and the turning plate 7056 also moves into the sliding plate 7057 because the clamping block 7082 on the square bar 7081 is clamped in the square groove 70562 of the turning plate 7056;

19. the first straight-stroke cylinder 7051 starts to work to drive the rack 7053 to move upwards, the rack 7053 is meshed with the gear 7054 to enable the gear 7054 to rotate 180 degrees, finally the turning plate 7056 rotates 180 degrees, and at the moment, 2 welding piece connecting belts 121 on the gluing core 10 on the turning plate 7056 are respectively aligned to the first long seam 7031 and the second long seam 7041;

20. the brush needle lifting cylinder 706 starts to work to drive the first brush needle chuck 703 and the second brush needle chuck 704 to move upwards, so that 2 welding sheet connecting belts 121 on the rubber core 10 are completely clamped in the respective first long seam 7031 and second long seam 7041;

21. the first needle brushing cylinder 701 and the second needle brushing cylinder 702 respectively start to work in a reciprocating mode at a high frequency, so that the soldering lug connecting belt 121 is subjected to fatigue fracture, finally, the soldering lug 11 on the soldering lug connecting belt 121 is left on the rubber core 10, and the redundant parts fall off;

22. the first straight-stroke cylinder 7051 starts to reset to drive the rack 7053 to move downwards, the rack 7053 is meshed with the gear 7054 to enable the gear 7054 to rotate reversely by 180 degrees, and finally the turning plate 7056 rotates reversely by 180 degrees;

23. the second straight stroke air cylinder 708 starts to reset, the second track 70561 on the turnover plate 7056 is moved to be aligned with the third track 141 on the rubber core stamping table 14, and the steps 11 to 13 are repeated;

24. the punched rubber core 10 with the soldering lug 11 falls into a bag through the blanking hopper 8.

The product of the invention continuously works without waiting, and a plurality of steps can work simultaneously, thus improving the efficiency and being similar to a production mode of a production line. The invention is not only suitable for vertical and horizontal products with 1.25mm spacing in the connectors, but also suitable for other indirect products, and only needs to change the size of the third rail 141 on the rubber core stamping platform 14 and replace the corresponding stamping die 601.

The present embodiment should not be construed as limiting the invention, but any modification made based on the spirit of the present invention should be within the scope of protection of the present invention.
