Pre-welding addressing method and system

A pre-welding addressing system, comprising at least:

• a frame body, a controller, a three-axis addressing mechanism, and an addressing camera module, wherein
• the three-axis addressing mechanism is mounted on the frame body and is capable of generating a movement relative to the frame body;
• the addressing camera module is mounted on the three-axis addressing mechanism;
• the addressing camera module is movable relative to the frame body as driven by the three-axis addressing mechanism;
• and
• the controller is electrically connected to the three-axis addressing mechanism and is configured to:
• obtain product information of a to-be-addressed battery pack, in response to the to-be-addressed battery pack getting in position, wherein the battery pack comprises a plurality of cells, and the product information comprises initial addressing coordinates of a plurality of cell terminal posts;
• obtain positioning deviation values of the plurality of cell terminal posts based respectively on the initial addressing coordinates of the plurality of cell terminal posts, wherein the positioning deviation values of the cell terminal posts are determined based on addressing images of the cell terminal posts that are acquired by the addressing camera module;
• and determine target addressing coordinates of the plurality of cell terminal posts based respectively on the initial addressing coordinates of the plurality of cell terminal posts and the positioning deviation values of the plurality of cell terminal posts.
