The intelligent electric screwdriver 18 moves up and down, which facilitates screw-tightening operations. The buffer mechanism 38 facilitates buffering and pressure detection of the intelligent electric screwdriver 18. When the screw is tightened, the screw cannot move further down. When the pressure sensor of the buffer mechanism 38 detects that the pressure has reached a preset threshold, the lifting motor 34 rotates in the opposite direction, driving the intelligent electric screwdriver 18 to rise.

[0025] In one embodiment, specifically: the lower part of the front surface of the mounting bracket 32 ​​is fixedly connected to the limiting slide rail 40, and the middle part of the rear surface of the lifting seat 36 is slidably connected to the outer wall of the limiting slide rail 40. The lifting seat 36 slides along the limiting slide rail 40, thereby increasing the movement stability of the lifting seat 36.

[0026] In one embodiment, specifically: a limiting seat 41 is fixedly connected to the bottom of the front surface of the mounting bracket 32, and the bottom of the outer side wall of the lead screw 35 is rotatably connected to the inner side wall of the limiting seat 41. The limiting seat 41 limits the lead screw 35, thereby increasing the stability of the rotation of the lead screw 35.

[0027] In one embodiment, specifically: protective covers 42 are fixedly connected to the upper parts of both sides of the mounting bracket 32, and the protective covers 42 facilitate the protection of the components installed on the mounting bracket 32.

[0028] In operation, the product is placed on the first feeding track 24 and the second feeding track 25 respectively. The first feeding track 24 and the second feeding track 25 transport the product to the corresponding first tooling fixture 21 and the second tooling fixture 22 respectively. At this time, the first longitudinal electric track 19 and the second longitudinal electric track 20 drive the first tooling fixture 21 and the second tooling fixture 22 to move, achieving precise docking with the first feeding track 24 and the second feeding track 25, ensuring that the product smoothly enters the first tooling fixture 21 and the second tooling fixture 22. At this time, the feeder 27 on the support frame 26 on the base 11 starts working, conveying the screw to the position where the intelligent electric screwdriver 18 can grasp it, providing material for the fastening operation; the first horizontal electric slide rail 13 and the second horizontal electric slide rail 15 respectively drive the two vertical lifting mechanisms 16 and the intelligent electric screwdriver 18 to move above the two feeders 27. The vertical lifting mechanism 16 starts, and the lifting motor 34 drives the lead screw 35 to rotate, causing the lifting seat 36 to descend, bringing the intelligent electric screwdriver 18 close to the screw and grasping the screw. After grasping the screw, the intelligent electric screwdriver 18 rises and resets. A horizontal electric slide rail 13 and a second horizontal electric slide rail 15 respectively drive two vertical lifting mechanisms 16 and an intelligent electric screwdriver 18 to move above the first tooling fixture 21 and the second tooling fixture 22, aligning them with the screw holes of the product. The vertical lifting mechanism 16 is activated, and the lifting motor 34 drives the lead screw 35 to rotate, causing the lifting seat 36 to descend and move the intelligent electric screwdriver 18 closer to the screw holes of the product. The intelligent electric screwdriver 18 drives the screw to rotate, tightening the screw onto the product. During the tightening process, the buffer mechanism 38 monitors the pressure in real time. When the screw reaches the appropriate tightening degree... When the pressure sensor detects the pressure threshold, the lifting motor 34 reverses and the intelligent electric screwdriver 18 rises. After locking is completed, the first longitudinal electric track 19 and the second longitudinal electric track 20 move again, driving the tooling fixture to move above the transfer track 28. The product flows out to the transfer track 28. If the product is qualified, the transfer track 28 moves to the discharge track 30, and the product is output through the discharge track 30 to enter the subsequent process. If the product fails the test (NG), the transfer track 28 connects to the NG storage area 31 and transports the unqualified product to the NG storage area 31 for storage.
