A pair of pressure plates are matched on the outside of the notch of the wire groove, and the pressure plate and the wire groove are surrounded to form a weld forming space, and a dubbing positioning tool is vertically matched in the weld forming space. The pressure plate is connected to a lifting cylinder, and the lifting cylinder is attached to the bracket, and the bracket is separated on both sides of the blade template.

[0005] In a preferred embodiment of the present invention, a blade-shaped copper strip is inlaid on the side edge of the pressing plate, and the edge of the blade-shaped copper strip matches the notch of the wire slot.

[0006] In a preferred embodiment of the utility model, one end of the blade template is connected to the base frame, and the other end is placed on a movable block. A movable shaft is inlaid in the movable block, and the movable shaft is installed on a flat base plate.

[0007] In a preferred embodiment of the present invention, the overlock positioning tool is a cylindrical rod with a diameter smaller than the width of the wire groove.

[0008] The beneficial effect of the utility model is that the blade battery welding tool provided by the utility model establishes a reference positioning by using a pressure plate to surround the wire groove to form a weld forming space, and uses a copying positioning tool to optimize the positioning accuracy, and adds copper bars to improve high-temperature reliability, thereby achieving efficient, accurate and rapid seam alignment and improving laser welding efficiency.

[0011] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] like Figure 1 As shown, the embodiment of the utility model includes:

[0013] A blade battery welding tool comprises a flat substrate 1, a base frame 2, a blade template 3, a copper bar 4, a wire groove 5, a pressure plate 6, a hemming positioning tool 7, a lifting cylinder 8, and a bracket 9. The flat substrate 1 is provided with a base frame 2, and a blade template 3 is horizontally suspended on the base frame 2. A copper bar 4 is installed on one side of the thickness side surface of the blade template 3, and a wire groove 5 is opened on the upper surface of the copper bar 4 along the thickness direction of the blade template 3. A pair of pressure plates 6 are matched with the outer side of the notch of the wire groove 5, and the pressure plates 6 and the wire groove 5 are surrounded to form a weld forming space, and a hemming positioning tool 7 is vertically matched in the weld forming space. The pressure plate 6 is connected to the lifting cylinder 8, and the lifting cylinder 8 is attached to the bracket 9. The bracket 9 is separated on both sides of the blade template 3.

[0014] The side edge of the pressing plate 6 is inlaid with a blade-shaped copper strip 10 , and the blade edge of the blade-shaped copper strip 10 matches the notch of the wire slot 5 .

[0015] Furthermore, one end of the blade template 3 is connected to the base frame 2 , and the other end is placed on a movable block 11 . A movable shaft is embedded in the movable block 11 , and the movable shaft is installed on the planar substrate 1 .

[0016] Furthermore, the overlock positioning tool 7 is a cylindrical rod with a diameter smaller than the width of the wire groove 5 .

[0017] Before using this device to weld the blade battery shell 100, it is necessary to first push the movable pier block 11 away from the blade template 3, then put the preformed battery shell material on the blade template 3, then reset the movable pier block 11 so that the pier block is reset and placed under the blade template 3, and then use the overlock positioning tool 7 to fine-tune the shaping and positioning of the preformed battery shell material based on the wire groove 5. Finally, the cylinder drives the pressing plate 6 to press and fix it, and then it can be sent to the laser welding machine for real-time seam welding. In order to further solve the problem of thermal stability of the tooling caused by laser welding, copper strips 4 and blade-shaped copper strips 10 are used to establish a weld forming space at the seam position where the laser is located, so that the high temperature generated during the welding process is isolated from the tooling as a whole and quickly discharged, thereby extending the service life.

[0018] In summary, the utility model provides a blade battery welding tool, which establishes a reference positioning by using a pressure plate 6 to surround the wire groove 5 to form a weld forming space, and uses a copying positioning tool 7 to optimize the positioning accuracy, and adds a copper strip 4 to improve high-temperature reliability, thereby achieving efficient, accurate and rapid seam alignment and improving laser welding efficiency.
