Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a high-quality automatic capping machine for batteries. Background Art

[0002] During the battery production process, after the internal components of the battery body are assembled, the battery body needs to be covered to form a sealed battery to be filled with electrolyte. In order to improve the production speed and quality of the battery, in the prior art, the battery cover is mostly closed by turning the battery upside down, and the closed battery is transported by a conveyor belt.

[0003] Chinese patent CN211578896 U discloses an automatic battery capping device, including a frame and a conveying mechanism and a capping mechanism arranged on the frame, the conveying mechanism includes a middle cover conveying assembly and a battery box conveying assembly respectively connected to the capping mechanism, the capping mechanism includes an ejection assembly that drives the middle cover to move upward to the battery box, and a flip assembly that flips the battery box upside down, wherein the flip assembly flips the battery box so that the battery box is located directly above the middle cover on the ejection component, and the positions of the battery box and the middle cover match each other. The utility model adopts the method of keeping the battery box stationary and moving the middle cover upward to perform the capping operation, avoiding the current conventional capping operation in which the middle cover is stationary and the battery box descends. Due to the large mass of the battery box, the large inertia when moving downward may cause the glue in the middle cover to overflow during the capping process, which not only affects the aesthetics of the battery, but also may cause too little glue to completely seal the battery.

When the battery mass is too large, the middle cover may move relative to the conveyor belt during transportation, causing wear and affecting the appearance of the battery. In addition, the positive and negative poles of the battery are protruding on the surface of the middle cover, which may be easily scratched during the transfer process, affecting the battery quality.

[0064] Working steps

[0065] Here, taking the steps of closing the covers of two consecutive groups of batteries 100 as an example, the battery body 101 of the first group enters the capping machine from the conveying mechanism 2, is flipped to the top of the lifting mechanism 5 by the flipping mechanism 3, the positioning mechanism 4 clamps and positions the flipped battery body 101, and the lifting mechanism 5 lifts the middle cover 102 so that it cooperates with the battery body 101 to complete the capping. The closed battery body 101 descends with the lifting mechanism 5 to the receiving station 61 of the receiving and transferring mechanism 6, and the receiving and transferring mechanism 6 transfers the closed battery 100 to the unloading station 62. Finally, the subsequent equipment transfers the closed battery 100 at the unloading station 62 to the subsequent process. During the process of closing the cover of the first battery group 100, the second battery group 101 also starts closing the cover. When the first battery group 101 is clamped and positioned by the positioning mechanism, the flipping mechanism 3 releases the first battery group 101 and flips it back to the tail end of the conveying mechanism 2 to load the second battery group 101. When the first battery group 100 is transferred to the discharge station 62, the second middle cover 102 enters the capping machine, and the flipping mechanism 3 flips the second battery group 101 to the top of the lifting mechanism 5, and repeats the capping process of the first battery group 100. After the first battery group 100 is transferred out of the capping machine, the receiving and transferring mechanism 6 returns from the discharge station 62 to the receiving station 61 to receive and transfer the second battery group 100. The above steps are repeated for continuous production.
