[0058] Working principle of the present invention:

[0059] First, the circular insert 2 is manually placed into the vibrating screen 11 of the automatic feeding mechanism, and the circular insert 2 is pushed onto the guide rail 1-2 by the vibration force generated in the vibrating screen 11, and moves along the guide rail 1-2 to the track insert grabbing and positioning platform 1-3. The insert grabbing and positioning platform 1-3 restricts the circular insert 2 from continuing to move forward, and the two mechanical arms 3 rotate to the track front end insert grabbing and positioning platform 1-3, and the circular insert 2 is rotated and grabbed by the first claw clamping mechanism of the two first insert clamping mechanisms. After grabbing a circular insert 2, the first claw clamping mechanism will automatically rotate to grab the next circular insert 2 until all five first claw clamping mechanisms 2 are fully grabbed. During the grabbing process, the first sensor 1-4 at the front end of the insert grabbing and positioning platform 1-3 will continue to detect. If a missed clamp is detected, the equipment will report an error and stop running.

[0060] Secondly, after the first insert clamping mechanism grabs, the first mechanical arm 3-1 rotates to the insert positioning column 5-1 of the insert positioning mechanism 5, accurately aligns with the insert positioning column 5-1, and sequentially places each circular insert 2 into the insert positioning column 5-1. The two first insert clamping mechanisms are each responsible for grabbing and placing half of the circular inserts 2. When the first insert clamping mechanism places all the inserts of the insert positioning column 5-1 on the pre-installation workbench 6 in place, the fourth detection sensor next to the insert positioning column 5-1 will perform wrong or missing detection on the circular insert 2. If it is detected that the circular insert 2 is wrongly installed or missing, the device will report an error and stop running.

[0061] Then, when the inspection is completed without error, the transfer mounting plate 4-4 is rotated to the guide positioning groove by the second mechanical arm of the secondary insert clamping mechanism 4, and the positioning guide column 4-5 cooperates with the guide positioning groove to ensure that the second claw clamping mechanism 4-3 grasps the position accurately. The second mechanical arm moves the transfer mounting plate 4-4 to the mold, and the positioning guide column 4-5 cooperates with the guide groove of the mold to accurately position it. The second claw clamping mechanism 4-3 delivers all the inserts on the pre-installation workbench 6 to the insert pre-installation position of the mold at one time, which improves work efficiency and avoids manual operation errors and personnel safety issues.

[0062] Finally, after the battery box cover is injection molded, the secondary insert clamping mechanism 4 will rotate into the mold to take out the workpiece. When taking out the workpiece, the vacuum suction cup 4-6 at the lower end of the transfer mounting plate 4-4 of the secondary insert clamping mechanism 4 will suck the workpiece tightly, and then grab the workpiece and place it on the platform.

[0063] The present invention not only accurately realizes the pre-installation of inserts and the identification of wrong or missing installation, greatly improves the utilization rate of materials and production efficiency, reduces the product missing installation rate, and thus effectively controls the production cost and product quality. Moreover, different fetal membranes can be flexibly replaced to realize the pre-installation of different inserts and the identification of wrong or missing installation, thereby improving the versatility of the equipment.
