[0022] In one embodiment of the present application, as Figs. 1-2As shown, the application provides a one-piece suction disc, which comprises a mounting plate 10, a sealing gasket 20 and a suction plate 30. The sealing gasket 20 is arranged between the mounting plate 10 and the suction plate 30, and the two surfaces of the sealing gasket 20 abut against the mounting plate 10 and the suction plate 30 respectively. The bottom of the mounting plate 10 is provided with a negative pressure cavity 11 which is open towards the sealing gasket 20, and the sealing gasket 20 is pressed on the negative pressure cavity 11. The mounting plate 10 is further provided with a plurality of negative pressure channels 12 which are in communication with the negative pressure cavity 11 and are used for connecting a negative pressure device. The bottom of the suction plate 30 is further provided with a plurality of suction nozzles 31 which are integrally injection molded with the suction plate 30. The suction plate 30 is further provided with a plurality of air passing channels 32 which penetrate through the suction plate 30 and are in one-to-one communication with the suction nozzles 31. The sealing gasket 20 is further provided with a plurality of air passing holes 21 which are matched with the air passing channels 32. In the embodiment, the suction plate 30 and the suction nozzles 31 are integrally injection molded, so that the manufacturing cost is greatly reduced. Meanwhile, the negative pressure cavity 11 on the mounting plate 10 is connected with the negative pressure device through the negative pressure channels 12. When it is needed to suck something, the negative pressure device is opened to generate negative pressure in the negative pressure cavity 11. The air passing holes 21 and the air passing channels 32 are in communication with the suction nozzles 31, so that the suction nozzles 31 can generate suction force to suck the product. Meanwhile, the negative pressure force among the suction nozzles 31 is balanced, so that the movement of the product is relatively stable.

[0023] Further, the suction nozzles 31 are arranged in a rectangular array on the suction plate 30. In the embodiment, the suction nozzles 31 are arranged in a rectangular array on the suction plate 30, so that the suction force is generated more stably.

[0024] Further, the suction nozzles 31 are integrally cylindrical, and the suction nozzles 31 are further provided with two annular grooves 33 which are recessed towards the suction nozzles 31. In the embodiment, when the suction nozzles 31 contact the product, a certain deformation is generated to provide a certain buffering force for the product, so that the product is not damaged by the suction nozzles 31.

[0026] Further, the application further comprises a mounting bracket 40, one end of which is connected with the mounting plate 10. In the embodiment, the one-piece suction disc provided by the application is mounted on a mechanical hand through the mounting bracket 40, so that the mounting plate 10 is not mounted, thereby avoiding affecting the connection between the negative pressure channels 12 and the negative pressure device.

[0027] Further, the mounting frame 40 comprises a crossbeam 41 and two support columns 42, one end of the two support columns 42 is connected to the two sides of the crossbeam 41 respectively, and the other end of the two support columns 42 is connected to the mounting plate 10.

[0028] Further, two sliding holes 43 are arranged at the two ends of the crossbeam 41, and the two support columns 42 are slidably connected in the two sliding holes 43 respectively, and the upper end of the support column 42 is further connected with a screw, the screw nut shaft diameter is greater than the hole diameter of the sliding hole 43, and the screw is matched with the mounting plate 10 to limit the sliding of the support column 42 in the sliding hole 43. In the embodiment, the support column 42 can slide in the sliding hole 43, when the suction nozzle 31 contacts the product, the support column 42 slides in the sliding hole 43, and the suction nozzle 31 abuts against the product by using the gravity of the mounting block and the suction plate 30, so as to suck up the product, and meanwhile, the rigid collision between the suction nozzle 31 and the product is avoided to cause damage to the product.

[0029] Further, the mounting frame 40 further comprises two reset springs 44, the reset spring 44 is sleeved on the support column 42, and one end of the reset spring 44 abuts against the mounting plate 10, and the other end abuts against the crossbeam 41. In the embodiment, the spring is used for resetting the mounting plate 10, so as to avoid that the support column 42 is stuck in the sliding hole 43, and the suction nozzle 31 cannot contact the product when sucking the material next time.
