[0024] In order to better understand the purpose, structure and function of the present utility model, the following will further describe in detail the specific embodiments of the "gasket material taking mechanism" of the present utility model in conjunction with the drawings.

[0025] See Figures 1 to 4, in this embodiment, the material taking mechanism includes a vacuum seat 100. An air passage 101 is arranged inside the vacuum seat 100. A vacuum joint 200 and a material suction head 300 communicating with the air passage 101 are arranged on the vacuum seat 100. The vacuum joint 200 is connected to a vacuum pump (not shown) to pump vacuum to provide suction. A positioning groove 301 is arranged at the front end of the material suction head 300. The shape of the positioning groove 301 is the same as that of the washer 400. The material suction head 300 is provided with a plurality of suction holes 302. The suction holes 302 communicate with the bottom surface of the positioning groove 301 and the air passage 101. The positions where the suction holes 302 are distributed can be adjusted according to the shape of the washer 400 to ensure that all the suction holes 302 can adsorb the washer 400. This mechanism can be used in cooperation with automated components such as a robotic arm. The vacuum holes are fixedly assembled at the rear end to the automated component. The vacuum pump is started. The material suction head 300 approaches the washer 400. The washer 400 is embedded into the positioning groove 301 for positioning. At the same time, since the shape of the positioning groove 301 is the same as that of the washer 400, the suction holes 302 located at the bottom of the positioning groove 301 can firmly adsorb the washer 400, ensuring that the washer 400 will not fall off during transfer and assembly. The material suction head 300 is preferably made of a metal material, which has higher wear resistance. The vacuum adsorption method will not suck metal impurities onto the washer 400 and affect the product quality. This washer material taking device has stable adsorption and high efficiency in sucking the washer 400.

[0026] Further refer to Figures 2 - 4 , in this embodiment, an avoidance groove 303 is arranged on the bottom surface of the positioning groove 301. The avoidance groove 303 avoids the suction holes 302. The positioning groove 301 and the avoidance groove 303 are coaxially arranged. The shape of the avoidance groove 303 is the same as that of the inner hole 401 of the washer 400. The suction holes 302 surround the avoidance groove 303. The function of the avoidance groove 303 is to prevent interference with the rubber roller during material taking or feeding, improving the feeding efficiency and stability.

[0027] More specifically, in this embodiment, the vacuum seat 100 and the material suction head 300 are detachably connected, which is convenient for repairing and replacing the material suction head 300. A sealing ring 102 is arranged between the vacuum seat 100 and the material suction head 300 to ensure the sealing performance. As a preference, a positioning groove 103 is arranged on the vacuum seat 100. A sealing groove 104 is arranged on the bottom surface of the positioning groove 103. A positioning block 304 is arranged at the rear end of the material suction head 300. When assembling, the sealing ring 102 is placed in the sealing groove 104. The positioning block 304 falls into the positioning groove 103 and abuts against the sealing ring 102. The vacuum seat 100 and the material suction head 300 are fixed by bolts to complete the sealed connection between the material suction head 300 and the vacuum seat 100.

[0028] Further refer to Figure 1 and Figure 2, in this embodiment, the vacuum connector 200 is detachably and sealingly connected to the vacuum seat 100 to facilitate the maintenance and replacement of the vacuum connector 200; of course, in other embodiments, the vacuum connector 200 and the vacuum seat 100 can also be designed to be integrally formed to increase the sealing performance.

[0029] Furthermore, in some embodiments, a vacuum pressure gauge can be provided on the vacuum connector 200. By the pressure value detected by the vacuum pressure gauge, it is determined whether there is an adsorption gasket 400 on the suction head 103 and whether the gasket 400 falls off during the transfer and feeding processes. This information is fed back to the central controller to guide the operation of the automation.
