[0016] The embodiments of the technical scheme of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0017] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as the usual meaning understood by the technical personnel in the field to which the present application belongs.

[0018] For example, Figure 1and Figure 2 As shown in the figure, a specific embodiment of this utility model provides a positioning fixture for welding copper sheets and copper busbars, including a guide rail module and a positioning slide 300; the guide rail module includes a base 100, on which a sliding guide rail and a drive slide 200 adapted to the sliding guide rail are provided, and a servo motor module for controlling the sliding of the drive slide 200 is provided inside the base 100; the positioning slide 300 is mounted on the drive slide 200, and a contour jig base plate 400 is provided at the upper end of the positioning slide 300, and a welding station 500 for accommodating the workpiece is provided on the contour jig base plate 400, and a plurality of detachable contour positioning blocks 600 are provided on the welding station 500.

[0019] like Figure 1 and Figure 2 As shown, through the above-described configuration, the positioning fixture in this embodiment includes a guide rail structure and a positioning structure. The guide rail module for conveying the workpieces to be welded relies on a high-precision linear sliding guide rail combined with a servo motor and a precision transmission device. The transmission device can be a synchronous belt, ball screw, or other existing technology, which will not be elaborated here. When the motor is controlled by a PLC or other controller, the positioning slide 300, which carries the workpieces such as copper sheets and copper busbars to be welded, can be accurately conveyed to the designated welding position by the drive slide 200. Its positioning accuracy can reach the millimeter level, thereby ensuring that the starting position of subsequent laser welding is accurate. The positioning slide 300 is equipped with a contour jig base plate 400 of the corresponding specification according to the welding requirements. The workpiece is placed in front of the welding station 500. The contour positioning block 600 is set according to the shape of the workpiece to perform welding positioning on the workpiece, ensuring that the workpiece is accurately and stably positioned during the welding process, thereby avoiding displacement of the welded workpiece and achieving high-precision positioning.

[0020] like Figure 1 and Figure 2 As shown, since the servo motor module of the guide rail module needs to be connected to the control signal line, in this embodiment, the servo motor module signal connection is located at the control wiring port 700 at the end of the base 100; during installation, the device can be connected to the controller's control wiring harness through the control wiring port 700. In order to limit the extreme displacement distance of the positioning fixture, this embodiment provides a limit photoelectric switch 800 at the end of the base 100 to limit the displacement limit position of the positioning slide 300. The limit photoelectric switch 800 is used to implement the limit, and it can automatically stop when the positioning fixture moves to the corresponding position. The limit photoelectric switch 800 can be connected to the controller device through the signal line to realize automated positioning.

[0021] like Figure 1 and Figure 2As shown, in order to improve the installation stability of the welding station 500, this embodiment has a stepped part 900 for installing the welding station 500 on the upper end of the contour jig base plate 400. At the same time, the contour jig base plate 400 has mounting holes on its edge. Through the mounting holes and bolts and other structures, it can be stably installed on the positioning slide 300.

[0022] When this equipment is used in conjunction with welding equipment, the operating steps are as follows: First, the workpiece to be laser welded (such as copper sheet and copper busbar) is accurately loaded into the welding station 500. The contour positioning block 600 can be adjusted into position according to the outline and size data of the workpiece to ensure that the workpiece will not be displaced during subsequent conveying and welding processes, and then the subsequent laser welding operation can be carried out.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
