The invention provides a control method and a control system both used for battery laser welding. The control method includes determining control information of a servo system on the basis of related information; sending out a starting signal to enable a laser source to be started, and sending out a linear interpolation signal to enable the servo system to drive an interpolation workpiece to move along a first direction to perform linear interpolation on a to-be-processed battery; on the basis of the control information, after the circumstance that the interpolation workpiece runs to a preset position along the first direction is determined, sending out a helix interpolation signal to enable the servo system to drive the interpolation workpiece to rotate around itself to perform helix interpolation on the to-be-processed battery; on the basis of the control information, after the interpolation workpiece rotates around itself by a preset angle, sending out a linear interpolation signal to enable the interpolation workpiece to repeat linear interpolation operation and helix interpolation so as to complete welding of the whole to-be-processed battery. By the control method and the control system, automatic control of battery laser welding can be realized.
Description
technical field [0001] The invention relates to the field of battery laser welding, in particular to a control method and system for battery laser welding. Background technique [0002] Mobile phones, notebooks, cameras and other products have been widely used in people's daily life and work. Lithium batteries as charging energy storage devices are an indispensable component of these products. Due to the liquid filling inside the metal lithium battery, the shell and the end cover must be strictly sealed. [0003] At present, some lithium battery manufacturers use ultrasonic waves to seal lithium batteries. For example, in the Chinese patent document with application number 200810123528.2, a lithium battery cap assembly is disclosed. The cap assembly includes: a cover plate, a diaphragm, a sealing ring and an orifice plate arranged up and down in sequence; the connection between the cover plate and the diaphragm, and between the orifice plate and the diaphragm can be greatl...
