Description

Technical Field

[0001] This invention belongs to the field of battery cover assembly technology, and specifically relates to a cover marking machine and its working method. Background Technology

[0002] In the production process of battery covers, QR codes need to be printed on the battery covers for labeling and identification.

[0003] While existing coding machines have solved many problems associated with manual feeding and scanning, there are still some issues that need to be addressed in actual production, as follows: 1. The current feeding mechanism can only transport one product at a time, resulting in slow conveying efficiency and requiring the robotic arm to pause and wait when grabbing a product. 2. The existing coding equipment can only process one product at a time, and its processing efficiency is low. Furthermore, after processing, the product needs to be manually flipped to meet the requirements of subsequent explosion-proof sheet welding, which requires additional personnel and results in a heavy workload for the staff. 3. Existing equipment uses a rotary wheel to flip the battery cover, which is prone to falling off during the flipping process and is unstable, leading to product damage and increasing the product defect rate.

[0004] Therefore, existing cover plate marking equipment still needs improvement. Summary of the Invention

During operation, the rotary drive cylinder 2615 drives the barcode scanning robot 2616 to rotate at the same angle as the flip-type receiving mechanism 2621. Then, the longitudinal and lateral movement modules drive the barcode scanning robot 2616 to move longitudinally and laterally. The vertical movement module 2614 drives the barcode scanning robot 2616 to move downward until the product grabbed by the barcode scanning robot 2616 is placed on the flip-type receiving component 26213 on the flip-type receiving mechanism 2621, and the suction cup releases the product.

[0038] The working principle of the cover plate coding machine described in this embodiment is as follows: First, the dual conveyor lines in the coding feeding mechanism 21 alternately feed the coding and feeding robot through the conveyor mechanism. The gripping device behind the coding and feeding robot grips the product onto the coding secondary positioning mechanism 22, and positions it through the coding secondary positioning mechanism 22. After secondary positioning, the product is picked up by the gripping device at the other end of the coding and feeding robot and placed onto the coding turntable fixture at the feeding station of the coding turntable. The coding turntable rotates the product to the lower coding inspection station, where it is inspected by the coding inspection mechanism 23. The upper camera inspects the size of the injection hole, burrs, and the front and back of the product, while the bottom camera inspects the size of the explosion-proof hole and burrs. Good products are rotated to the coding station by the coding turntable after inspection, while defective products are rejected. The laser marking mechanism engraves codes on the products 24 times; The code reading and testing agency 25 reads the code engraved in the previous step and tests the QR code level; The barcode-scanning and unloading robot 2616 in the barcode-scanning and unloading mechanism 26 picks up the reversed product and places it into the barcode-scanning NG box 263. The robot then picks it up and transports it to the NG conveyor line 264 to the designated position. Good products are placed on the flip-type receiving mechanism 2621. The rotary drive cylinder 2615 drives the barcode-scanning robot 2616 to rotate at the same angle as the flip-type receiving mechanism 2621. Then, the longitudinal and lateral movement modules drive the barcode-scanning robot 2616 to move longitudinally and laterally. The vertical movement module 2614 drives the barcode-scanning robot 2616 to move downward until the product picked up by the barcode-scanning robot 2616 is placed on the flip-type receiving component 26213 on the flip-type receiving mechanism 2621, and the suction cup releases the product. The flipping receiving mechanism 2621 flips the product onto the barcode scanning and discharging mechanism 2623 below. Specifically, the lifting drive cylinder 26216 first drives the flipping receiving component 26213 to move upward to the designated position. Then, the flipping drive cylinder 26215 drives the flipping drive frame 26214 to move the rack 26220 forward. During the movement of the rack 26220, the flipping drive wheel 26219 will rotate. During the rotation of the flipping drive wheel 26219, the flipping shaft 26218 will drive the flipping receiving component 26213 to rotate together to achieve flipping, flipping the product into the placement cavity on the corresponding dual-line discharging module 2622. The dual-line discharge module 2622 drives the barcode scanning and discharge mechanism 2623 to move, thus conveying the product to the next process.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
