The cross section of the sliding groove 51 is arranged in an arc shape, and the sliding groove 51 is eccentrically arranged with the rotation axis of the driving turntable 5. A cam follower 411 is provided at one end of the driving block 41 close to the driving turntable 5. The cam follower 411 is slidably connected to the inner wall of the sliding groove 51. The other end of the driving block 41 is fixedly connected to a support block 42. The support block 42 extends in the vertical direction and passes through the through opening. The clamping block 4 is arranged at the end of the support block 42 away from the driving block 41. A notch is provided for the support block 42 to pass through. The support block 42 is annularly arranged. A support member 111 that can pass through the support block 42 is fixedly connected to the notch. A first linear slide rail 112 is fixedly connected to the bottom of the support member 111. A first sliding block 412 that slidably cooperates with the first linear slide rail 112 is fixedly connected to the top of the driving block 41. The arrangement of the first linear slide rail 112 and the first sliding block 412 limits the moving trajectory of the driving block 41 and ensures the stability of the movement of the driving block 41; a second linear slide rail 113 is fixedly connected to the top of the support member 111, and a second sliding block 43 that slidably cooperates with the second linear slide rail 113 is fixedly connected to the bottom of the clamping block 4, which limits the moving trajectory of the clamping block 4 and makes the movement more stable;

The clamping block 4 is symmetrically provided with a first positioning block 44 on one side close to the work station 21, and the first positioning block 44 abuts against the rear shell of the product, and the first positioning block 44 is used to complete the centering of the positioning rear shell, thereby ensuring the positioning effect of the rear shell of the product; the clamping block 4 is symmetrically provided with a second positioning block 45 on the top of one side close to the work station 21, and the second positioning block 45 abuts against the product cover plate, and the second positioning block 45 is provided with a support portion for carrying the product cover plate on the side away from the clamping block 4. The support portion is provided, and the product cover plate can be better placed. When placing it, the second positioning block 45 is used to complete the centering of the product cover plate, thereby ensuring the assembly quality. A groove is provided on the top of the tightening block 4, and a cover plate positioning block 46 is connected to the groove in a horizontal sliding direction. A protrusion is provided on the side of the cover plate positioning block 46 away from the support block 42 and is located between the two second positioning blocks 45. A second elastic member 422 is provided on one side of the support block 42. The second elastic member 422 has elastic deformation potential energy for driving the protrusion toward the second positioning block 45 so that the protrusion extends out of the groove. By providing the cover plate positioning block 46, when the product cover is placed on the top of the support portion, the elasticity of the second elastic member 422 can be used to push the cover plate positioning block 46 so that the cover plate positioning block 46 is close to the product cover and further positioned, thereby achieving a centering effect, further ensuring the positioning effect of the product cover and the assembly quality of the overall equipment. A linear guide is also provided on the inner bottom wall of the groove to slide with the cover plate positioning block 46 to limit the movement trajectory of the cover plate positioning block 46;

The second positioning block 45 contacts the product cover to complete the positioning of the product cover. At this time, the vacuum suction cup 7 of the lower tool 31 is used to adsorb the product back shell to prevent the product back shell from moving; then the upper carrier 2 is pressed down by the pressing module 3. After the upper carrier 2 approaches the product cover, the vacuum suction cup 7 is also used to adsorb the product cover to prevent the product cover from moving;

[0032] After the adsorption is completed, the drive turntable 5 is reversed, driving the four drive blocks 41 to move away from each other, so that the first positioning block 44 and the second positioning block 45 are away from the product back shell and the product cover. At this time, the upper carrier 2 is pressed down to complete the pressing of the upper carrier 2 and the lower carrier 31, and at the same time complete the covering of the product cover and the product back shell, completing the assembly of the product.
