Abstract: Embodiments of the present disclosure provide a pre-welding addressing method and system.

Abstract: A pre-welding positioning system includes 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. 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. 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 to fix the battery pack to the frame body by the fixing component.

Abstract: Embodiments of the present disclosure provide a battery welding system and a control method therefor. The battery welding system includes a welding module including a welding apparatus, a driving assembly and a plurality of range finders, wherein at least some of the range finders are connected to a driving end of the driving assembly, and the driving assembly drives the range finders to move in a first direction such that a separation distance between the range finders in the first direction changes. In the battery welding system in the embodiments of the present disclosure, the driving assembly driving the range finders to move enables the separation distance between the range finders in the first direction to change, so that the separation distance between the range finders can correspond to a separation distance between regions to be welded on the battery without disassembling the range finders.

Abstract: This application provides a dust extraction apparatus and a battery production line. A copper nozzle is disposed on a first end face of a cover plate, and a channel of the copper nozzle communicates with a through hole of the cover plate. A dust extraction assembly is disposed on a second end face, and a cavity having a first port and a second port is formed in the interior of the dust extraction assembly. The first port faces the through hole, and a suction apparatus is connected to the second port. The dust extraction apparatus in embodiments of this application can extract dust via the first port of the dust extraction assembly facing the through hole, thus promptly exhausting impurities such as smoke and welding slag generated during welding.

The second direction intersects the first direction.

Abstract: Laser emitted by a laser device is guided to an oscillating mirror and a power detection apparatus by a light guide portion. This allows the oscillating mirror to output laser for performing laser welding operations on a welding object. This also allows the power detection apparatus to detect, through a photoelectric conversion component, an electrical signal corresponding to the laser emitted by the laser device, and to determine, through a computing component based on the electrical signal and a preset conversion relationship, a laser power corresponding to the laser emitted by the laser device. The power detection apparatus is disposed on an optical conduction path between the laser device and the oscillating mirror, so that the laser power of the laser device can be detected in real time during the operation of the laser welding machine without removing the QBH connector and the oscillating mirror.
