Further, based on the embodiment shown in fig. 3, a second embodiment of the tab cutting method of the present invention is proposed. Referring to fig. 4, fig. 4 is a schematic view of a cutting area of the substrate according to the present invention.
The acquiring of the profile information of the tab comprises the following steps:
step S101: acquiring substrate information;
specifically, the tab has a specific shape, and the control device can receive information of the whole roll of the substrate, which is imported by a worker, including but not limited to the size, material, thickness and the like of the substrate.
Step S103: determining cutting positions of a plurality of tabs according to the base material information, wherein the cutting positions comprise a plurality of vertical cutting positions and a plurality of horizontal cutting positions;
specifically, in fig. 4, reference numeral 1 denotes a tab cutting region. The control equipment can plan the cutting region of utmost point ear on the substrate according to the shape of utmost point ear, plans the cutting position of a plurality of utmost point ears on the cutting region, and the cutting position of every utmost point ear all comprises two perpendicular cutting positions and a horizontal cutting position, still has certain clearance between two utmost point ears simultaneously, therefore still has a horizontal cutting position between two utmost point ears. The direction of the horizontal cutting position coincides with the conveying direction, and the direction of the vertical cutting position is perpendicular to the direction of the horizontal cutting position, i.e., the direction of the vertical cutting position is perpendicular to the conveying direction. Each vertical cutting position is connected with each horizontal cutting position in sequence, so as to form a continuous cutting position of a plurality of tabs, and referring to fig. 5, fig. 5 is a schematic diagram of a cutting position of a base material, 20 is a vertical cutting position, and 30 is a horizontal cutting position.

step S502: determining the offset motion parameter of the offset motion of the galvanometer system on the conveying plane of the winding machine according to the vertical profile information.
Specifically, the control device may determine the current cutting position of the galvanometer system as the vertical cutting position according to the currently identified vertical profile information, and determine the operation speed of the primary motion parameter as the operation speed of the winding machine according to the vertical profile information. And because the base material is conveyed along the preset direction through the winding machine, the cutting light spot formed by the laser beam output by the mirror vibrating system can not accurately cut the vertical cutting position only by moving according to the main motion parameter and the laser cutting parameter, and can not cut to form a vertical cutting seam vertical to the conveying direction, so that the mirror vibrating system needs to perform offset motion, and the direction of the offset motion is vertical to the conveying direction. And determining the offset motion parameter of the offset motion in the offset direction, and determining the composite motion parameter of the galvanometer system according to the main motion parameter and the offset motion parameter. Namely, the motion direction and the motion speed of X, Y two motors of the galvanometer system are determined, so that a cutting spot formed on the base material by a laser beam emitted by a laser moves to cut according to the composite motion parameters, and a vertical kerf of the vertical structure of the tab corresponding to the base material is obtained.
In this embodiment, the profile information is the vertical profile information; the determining of the offset motion parameter of the offset motion of the galvanometer system on the conveying plane of the winding machine according to the profile information comprises: determining the offset motion parameter of the offset motion of the galvanometer system on the conveying plane of the winding machine according to the vertical profile information.

Further, based on the embodiment shown in fig. 3, a fourth embodiment of the tab cutting method according to the present invention is provided.
The contour information is the horizontal contour information;
step S50: determining an offset motion parameter of an offset motion of the galvanometer system on a conveying plane of the winding machine according to the profile information, wherein the offset motion parameter comprises:
step S504: determining the offset motion parameter of the offset motion of the galvanometer system on the conveying plane of the winding machine to be 0 according to the horizontal profile information;
specifically, the control device may determine the current cutting position as the horizontal cutting position according to the currently identified horizontal contour information. When the current cutting position is the horizontal cutting position, the mirror system that shakes need not carry out the migration motion, if carry out the migration motion, can't form the horizontal joint seam in the horizontal cutting position. The offset motion parameter of the offset motion is thus 0.
Step S70: determining a composite motion parameter of the galvanometer system according to the main motion parameter and the offset motion parameter, wherein the composite motion parameter comprises:
step S702: and determining the composite motion parameter of the galvanometer system according to the main motion parameter.
Specifically, when the cutting position of the galvanometer system is the horizontal cutting position, the running speed of the galvanometer system in the main motion parameter along the conveying direction is also 0, that is, the galvanometer system cannot move along the conveying direction. The control equipment determines that the composite motion parameter is 0 according to the main motion parameter and the offset motion parameter, so that when the cutting position of the mirror vibration system is a horizontal cutting position, X, Y motors of the mirror vibration system do not need to operate, namely the control equipment can control an optical lens in the mirror vibration system to be fixed at the current position, a laser beam output by the laser is fixed at the starting point of the horizontal cutting position, a cutting spot formed on the base material by the laser beam emitted by the laser according to the laser cutting parameter is cut according to the motion of the base material, and a horizontal structure of the lug corresponds to a horizontal cutting seam on the base material, and a horizontal structure between the two lugs corresponds to a horizontal cutting seam on the base material.
In this embodiment, the profile information is the horizontal profile information; the determining of the offset motion parameter of the offset motion of the galvanometer system on the conveying plane of the winding machine according to the profile information comprises: determining the offset motion parameter of the offset motion of the galvanometer system on the conveying plane of the winding machine to be 0 according to the horizontal profile information; determining a composite motion parameter of the galvanometer system according to the main motion parameter and the offset motion parameter, wherein the composite motion parameter comprises: and determining the composite motion parameter of the galvanometer system according to the main motion parameter. The continuous and uninterrupted cutting of the base material in the conveying direction is completed by the laser under the movement of the base material, the tab cutting speed of the laser is improved, and the working efficiency of processing the tab is improved.
