The positioning block 83 has a positioning slot opening upward, which matches the lower end of the positioning seat 3. When the positioning seat 3 rotates with the turntable 1 to the bottom of the dispensing valve 63, the fourth telescopic drive member 81 drives the second motor 82 and the jacking bolt 83 to rise synchronously. The jacking bolt 83 lifts the anti-rotation pin 4 so that the anti-rotation pin 4 disengages from the anti-rotation slot 31, thereby releasing the lock on the positioning seat 3. Then, the second motor 82 drives the positioning seat 3 to rotate through the cooperation of the positioning slot and the lower end of the positioning seat 3. In this way, the product to be dispensed rotates, allowing the dispensing valve to apply a circle of glue around the electrical connector 200 of the vehicle-mounted camera on the positioning seat 3, so that the back cover 100 of the vehicle-mounted camera and the electrical connector 200 are riveted and firmly bonded by the glue 300. When the fourth telescopic driving member 81 retracts, the lifting bolt 83 and the second motor 82 descend, and the anti-rotation pin 4 automatically falls back into one of the anti-rotation grooves 31 under the action of gravity, re-locking the positioning seat 3.

[0057] The lower end of the positioning seat 3 of the present embodiment is square, and the positioning groove has two opposite groove walls. In other embodiments, the lower end of the positioning seat 3 can also adopt other non-circular shapes, such as pentagonal, elliptical, special-shaped, etc., and the positioning groove on the positioning block 83 adopts a corresponding shape to drive the positioning seat 3 to rotate. There are four anti-rotation grooves 31 evenly distributed on the side of the positioning seat 3 of the present embodiment. Every time the positioning seat 3 rotates 90°, the anti-rotation pin 4 corresponds to the next anti-rotation groove 31. In other embodiments, the number of anti-rotation grooves 31 is not limited to this, and the distance between the anti-rotation grooves 31 can be adjusted according to actual needs. As shown in the figure, the positioning seat 3 of the present embodiment is composed of multiple parts. In other embodiments, the positioning seat 3 can also be integrally formed.

The third telescopic drive element 73 drives the finger cylinder 74 up and down. Products coated with glue 300 move along the turntable 1 to the bottom of the material receiving mechanism 7. The finger cylinder 74 is used to pick up the glued products 300 from the positioning seat 3. The material receiving mechanism 7 removes the products from the positioning seat 3 and places them in the material tray 400. The workbench is also equipped with a magazine 500 for defective products, a storage area 600 for unprocessed products, and a storage area 700 for finished products.

[0060] If only one tray 400 is placed on the workbench, when the tray 400 is full, the equipment needs to be stopped to replace the tray 400, which wastes time. Therefore, preferably, a receiving tray assembly is provided below the receiving mechanism 7 of this embodiment. The receiving tray assembly includes a carrier tray 9, a tray 400, and a rotary drive 10. At least two trays 400 are placed on the carrier tray 9. The rotary drive 10 drives the carrier tray 9 to rotate to replace the tray 400. When one of the trays 400 is full of products, the rotary drive 10 promptly rotates the tray 400 turntable 1, avoiding the need to wait for the tray 400 to be replaced. The rotary drive 10 can be a rotary cylinder, a servo motor, etc.
