[0003] Especially during the battery packaging process, the battery needs to be automatically labeled and wrapped. However, at present, it is difficult to stick the battery trademark. On the one hand, the position of the trademark needs to be adjusted before the battery is labeled, so that the position of the trademark corresponds to the position of the battery when it is placed in the labeling device. On the other hand, since the trademark is flat, it is difficult to stretch it out, so it is difficult to wrap the trademark on the battery smoothly and accurately. The main reason is that the trademark is a very thin plastic paper, which is difficult to fully unfold when the label is put on, making it difficult to wrap the battery, which is easy to produce defective products, thereby affecting the production progress of the subsequent assembly line and affecting production capacity.

[0004] Therefore, the above-mentioned problems are issues that should be considered and solved in the process of battery production, so as to improve the level of mechanical automation production of batteries. Summary of the invention

[0008] A further improvement of the present invention is that in the heat shrinking process, after the heat-shrunk batteries are grouped, the battery combination is heat-shrunk as a whole to achieve plastic sealing packaging before entering the boxing line.

[0009] A further improvement of the present invention is that the trademark transition device includes a front transition device and a rear transition device connected up and down to adjust the direction of the trademark after shearing, wherein the front transition device is connected to the shearing machine and the rear transition device is connected to the labeling machine.

[0010] A further improvement of the present invention is that the sleeve labeling machine includes a passive sleeve labeling device and a trademark expansion device, wherein the passive sleeve labeling device realizes the positioning and pushing of the battery, and the trademark expansion device allows the trademark to be fully expanded, so that the trademark is completely wrapped on the battery.

[0011] A further improvement of the present invention is that the heat shrinking production line also includes a detection process and a rejection process, and unqualified products after heat shrinking are detected and rejected.

[0041] The present embodiment provides a battery trademark labeling device, wherein the first turntable 402 is driven by the first transmission shaft 401, the second turntable 502 is driven by the second transmission shaft 501, and the working disk 203 is driven by the hollow 201 to realize simultaneous rotation. After the PVC trademark tape is sheared, the trademark 000 is sucked longitudinally by the second suction nozzle 405 through negative pressure and enters the front transition device 400 (negative pressure is achieved by a vacuum pump). The rotation of the first transmission shaft 401 drives the first turntable 402 to rotate, and the rotation of the first turntable 402 drives the second suction nozzle 405 to rotate toward the rear transition device 500. When the first turntable 402 rotates, the third cam guide 408 is started to drive the connecting rod 410 to move, so that the connecting rod 410 drives the rack 412 moves up and down to drive the gear 411 to rotate, and the gear 411 drives the second suction nozzle 405 to rotate axially. The second suction nozzle 405 rotates 90 degrees together with the trademark and then passes it to the third suction nozzle 404. When entering the rear transition device 500, the PVC trademark is sucked by the third suction nozzle 404, and then the second turntable 502 rotates in the direction of the next process. While the second turntable 502 rotates, the second cam guide 509 is started, driving the second swing arm 508 to rotate, so that the third suction nozzle 504 rotates around the shaft 507. After the third suction nozzle 504 rotates 90 degrees in a circle, when the second turntable 502 rotates to transition with the working disk 203, the direction of the trademark 000 turns to the horizontal and then is passed to the first suction nozzle.

[0042] When the working disk 203 rotates and drives the swing rod 312 to rotate along the plane cam 205 to the concave arc segment 2068 of the plane cam 205, the angle of the swing rod 312 makes the first suction nozzle A303 and the first suction nozzle B304 close and clamp the trademark 000, and then the swing rod 312 rotates upward. During the gradual rotation, the angle of the swing rod 312 is adjusted. At this time, the protrusion on the first swing arm A301 pushes upward and drives the protrusion on the first swing arm B302, so that the first swing arm B302 rotates. At this time, the tension spring 307 is pulled open, and the first suction nozzle A303 and the first suction nozzle B304 suck the PVC trademark and open, thereby propping up the PVC trademark so that the battery can enter. At the same time, in the corresponding pushing assembly, the second cam guide 103 is started to move the second slider 106 forward, thereby driving the second push rod 108 to move the positioning seat 112 forward, so that the front end of the spring sheet 113 enters the trademark for the battery. The first suction nozzle is then turned to the outlet transition plate 316, and the angle of the swing rod 312 is the smallest when it is at the concave arc section 2068 of the plane cam 205, so that the first suction nozzle can be closed. Then, the angle gradually increases when the plane cam 205 rotates, so that the battery can smoothly enter the PVC trademark. Then, the angle remains unchanged until the swing rod 312 rotates to the outlet 315 with the plane cam 205. At this time, the suction nozzle is cut off, and the angle of the swing rod 312 increases, so that the first suction nozzle A303 and the first suction nozzle B304 are opened to the maximum to facilitate the falling of the packaged batteries, and then transferred to the next process through the outlet transition plate 316.

[0043] In the labeling assembly line, the front transition device and the rear transition device are used to rotate and adjust the direction of the trademark to meet the needs of labeling in the next process, and the first suction nozzle assembly is used to suck the two sides of the trademark, so as to completely open the trademark, so that the battery can enter the trademark completely and smoothly, and then the ejector rod and the spring sheet are used to push the battery into the trademark through the positioning hole, so that the trademark can be wrapped on the battery smoothly and accurately, ensuring the stability of the labeling process, realizing automatic labeling of batteries and trademarks, and improving production efficiency.

[0044] The beneficial effects of this embodiment are as follows: its structure is simple, and by setting up mutually coordinated assembly lines, the integration and continuity of battery automated packaging production are achieved, and the flexible transfer of battery materials in the packaging process is achieved, especially in the labeling assembly line, after the label tape is cut, the direction of the trademark is rotated and adjusted by the front transition device and the rear transition device, and then the trademark is wrapped on the battery smoothly and accurately, ensuring the stability of the labeling process, realizing automatic labeling of batteries and trademarks, and then automatically and continuously completing the heat shrinking and boxing processes, and having the ability of assembly line operation, thereby improving the level of mechanical automation production of batteries and improving production efficiency.
