[0003] Traditional packaging equipment usually places lithium batteries on a conveyor line, which then transports them to the packaging assembly for packaging. However, due to certain errors in the installation of the conveyor belt, lithium batteries can easily deviate from the predetermined path during transportation and fail to reach the packaging position accurately, requiring manual stop adjustments, which affects production efficiency.

[0004] Therefore, the utility model provides a soft-pack lithium battery packaging device to solve the problems raised in the above background technology. Utility Model Content
