It can automatically complete tasks such as grabbing, handling and placing materials through preset programs or external signal control, thereby improving production efficiency, reducing labor intensity and ensuring product quality.

[0003] In order to ensure the stability of material grabbing, the center of the material being grabbed should coincide with the center of the chuck. However, the automatic material grabbing mechanisms currently on the market usually use a chuck to grab neatly placed items. When grabbing unevenly placed materials, it is difficult for the center of the material to coincide with the center of the chuck, resulting in poor stability of the chuck material grabbing, which greatly limits the application scenarios of automatic material grabbing. Therefore, in order to achieve the coincidence of the chuck center and the material center and ensure stable automatic loading and unloading of the chuck, it is of great significance to design a quick-adjustment automatic material grabbing mechanism.

Intermediate positioning screws 14 are provided between the adjustment plates 12, angle adjustment screws 15 are provided between the intermediate adjustment plate 9 and the front and rear swing angle adjustment plates 10, and between the lower connecting plate 11 and the left and right swing angle adjustment plates 12, and the number of the angle adjustment screws 15 is two, and the front and rear swing angle adjustment plates 10 and the left and right swing angle adjustment plates 12 are provided with swinging grooves 16 used in conjunction with the angle adjustment screws 15, and there is a certain movable gap between the front and rear adjustment plates 7 and the intermediate adjustment plate 9, and between the intermediate adjustment plate 9 and the lower connecting plate 11. Through the angle adjustment mechanism 4, when the grabbing chuck 3 grabs the material, even if the center position of the material does not coincide with the center of the grabbing chuck 3, during the process of grabbing the material, the grabbing chuck 3 can automatically adjust the front, rear, left and right angles through the relative action of the grabbing chuck 3 and the material, thereby achieving the coincidence of the center of the material with the center of the grabbing chuck 3, so that the grabbing chuck 3 has better stability in grabbing the material.

[0025] Preferably, the material grabbing chuck 3 includes a chuck seat 17 fixedly disposed on the lower connecting plate 11 , and claws 18 are slidably disposed below the chuck seat 17 , and the number of the claws 18 is three.

The operator uses a syringe to inject lubricating oil into the oil chamber 22 through the sealing protrusion 26 with a tiny needle. After the injection is completed, due to the nature of the sealing gasket 25, the tiny pinhole will be squeezed to prevent the pinhole from leaking. By clamping the output end of the driving device in the driving groove 24 of one of the bevel gears 20, the bevel gear 20 is rotated to drive the gear plate 19 to rotate, and then the claw 18 is controlled to clamp and grasp.

[0029] Preferably, a spiral strip 27 is fixedly provided at the bottom of the gear plate 19, and a slide plate 28 that can slide in the groove of the spiral strip 27 is fixedly provided on the claw 18. When the gear plate 19 rotates, the spiral strip 27 will exert a force on the slide plate 28 on the claw 18, thereby controlling the movement of the claw 18.
