PRE-WELDING POSITIONING SYSTEM AND METHOD

The present disclosure discloses a pre-welding positioning system and method, the pre-welding positioning system including: a frame body, a controller, a three-axis mechanism arranged on the frame body, and a vision acquisition system and a fixing component arranged on the three-axis mechanism, where the controller is configured to control the three-axis mechanism to move to a designated position based on product information of a battery pack to be welded; the vision acquisition system is configured to acquire, at the designated position, an image of a positioning component of the battery pack, in response to the three-axis mechanism reaching the designated position; and determine a distance deviation value between the positioning component and a preset reference point based on the acquired detection image; and the controller is further configured to control the three-axis mechanism to drive the fixing component to the positioning component based on the distance deviation value so as to fix the battery pack to the frame body by the fixing component.
