[0064] The reset spring 27 is installed between the bottom of the piston 24 and the adsorption cavity 25, an air passage 36 is arranged on the push column 28, an adsorption hole 37 is arranged on the end surface of the needle suction disc body 18, the adsorption hole 37 is communicated with the installation cavity 26, one end of the air passage 36 extends to the bottom of the piston 24, and a spacing is reserved between the other end of the air passage 36 and the installation cavity 26; after the needle pins 31 extend out of the end surface of the needle suction disc body 18, the air passage 36 is communicated between the adsorption cavity 25 and the installation cavity 26. An air extraction hole 38 is arranged at the bottom of the adsorption cavity 25, and the air extraction hole 38 is connected with a negative pressure pipeline.

[0065] The adsorption cavity 25 is extracted through the air extraction hole 38 to generate negative pressure in the adsorption cavity 25, so as to move the piston 24, the push column 28 moves with the piston 24 to make the needle pins 31 extend out of the end surface of the needle suction disc body 18 and realize the needle hooking action, at this time, the air passage 36 is communicated between the adsorption cavity 25 and the installation cavity 26, so that the adsorption hole 37 generates negative pressure at the position, and the net plate is further adsorbed by vacuum, thereby improving the reliability of the net plate grabbing.

[0066] The filter screen plate is hooked by the needle punching suction disc module 9 to realize the screen hanging operation of the screen plate, and continuous production is realized, and the operation of stopping and replacing the double-sided adhesive tape is omitted. Specifically, the mechanical hand mounting plate 1 is mounted on the mechanical arm, the mechanical arm drives the needle punching suction disc module 9 to the screen plate position, the color recognition sensor 10 recognizes the color of the screen plate, if there is no screen plate empty frame product can be detected by the color recognition sensor 10, the color recognition sensor 10 alarms and the device stops moving, so that the operator can quickly repair. The filter screen plate mechanical hand screen hanging device eliminates the operation of stopping and replacing the double-sided adhesive tape, and can alarm the empty frame to facilitate quick repair.

[0067] As shown in Figure 3 single hole working mode, the filter screen plate mechanical hand screen hanging device hooks the screen plate on the workbench, moves to the front mold single cavity 39 in the mold to fix the screen plate, after injection molding, the rear mold cavity ejector pin 40 ejects the screen plate product, the color sensor identifies whether the screen plate product is missing, and the mechanical hand takes out the screen plate product from the mold cavity to the product box.
