DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0025] Reference Figure 1The adjustable welding mechanism of the foil winding machine in one embodiment of the present invention includes a workbench 1, an abutting assembly 2, a frame 3, a welding frame 4 and a driving assembly 5.

[0026] Reference Figure 2 , multiple workbenches 1 are provided, and the multiple workbenches 1 are independently provided. Any workbenches 1 can be driven to slide in the same direction, so that different workbenches 1 are combined to form welding surfaces of different sizes. In this embodiment, a first slide rail 6 is installed on the frame 3, and the multiple workbenches 1 are slidably connected to the first slide rail 6. By sliding different workbenches 1, the corresponding welding surface can be adjusted according to the size of the copper busbar and copper foil, thereby facilitating subsequent welding work.

[0027] Reference Figure 2 and Figure 3 The abutment assembly 2 is mounted on one side of the workbench 1. The abutment assembly 2 includes an abutment plate 21, which can be driven close to the workbench 1 to abut and secure the copper busbar and copper foil to the workbench 1. Therefore, during welding, the copper busbar and copper foil are first mounted on the workbench 1, and then the abutment plate 21 is driven close to the copper busbar and copper foil to abut and secure them, thereby facilitating subsequent welding work.

[0028] Continue to refer to Figure 2 and Figure 3 In this embodiment, the abutment assembly 2 also includes a second slide rail 22, a driving member 23, a slider 24 and a connecting rod 25. The second slide rail 22 is mounted on the frame 3 and is located on one side of the first slide rail 6. The driving member 23 is slidably connected to the second slide rail 22, and the driving member 23 is used to drive the abutment plate 21 to move closer to or away from the workbench 1. Specifically, the slider 24 is slidably connected to the second slide rail 22, and the driving member 23 is mounted on the slider 24. The connecting rod 25 is fixedly connected to the side of the abutment plate 21 away from the workbench 1, and one end of the connecting rod 25 is rotatably connected to the output end of the driving member 23, and the other end is rotatably connected to the slider 24, so that the abutment plate 21 rotates. In this embodiment, the driving member 23 can be a cylinder or a linear motor, etc.

[0029] When the driving member 23 drives the connecting rod 25 to move, the connecting rod 25 drives the abutting plate 21 to rotate, so that it can be close to or away from the workbench 1. Among them, the abutting plate 21 in this embodiment is provided with a folded edge, which is convenient for fixed installation with the connecting rod 25.

[0030] Reference Figure 2The number and position of the abutment plates 21 and driving members 23 correspond one-to-one with the workbench 1. Each driving member 23 drives one abutment plate 21 toward or away from the workbench 1. In this embodiment, three sets of abutment plates 21, driving members 23, and workbench 1 are provided. It will be appreciated that each set of driving members 23 can independently drive a corresponding abutment plate 21 toward or away from the corresponding workbench 1. The independent provision of each set facilitates flexible combination and use by relevant personnel.

[0031] Reference Figure 1 and Figure 2 The frame 3 includes two opposing support arms 31, with the second slide rail 22 rotatably connected between the support arms 31. A connecting bracket 7 is fixedly connected between the second slide rail 22 and the first slide rail 6. Therefore, when the second slide rail 22 rotates, it can also drive the first slide rail 6 to rotate, thereby adjusting the angle of the worktable 1. This further enhances the flexibility of the adjustable welding mechanism of the foil winding machine in this embodiment, thereby improving its adaptability to different copper bars and copper foils. Operators can freely combine welding surfaces of different sizes and adjust the rotation angle of the welding surface.

[0032] Reference Figure 1 The welding frame 4 is used to adjust the position of the welding gun. The frame 3 also includes a connecting plate 32 fixedly connected between the two support arms 31. The welding frame 4 is slidably connected to the connecting plate 32. The sliding direction of the welding frame 4 is the same as the sliding direction of the workbench 1. By sliding the welding frame 4, the position of the welding gun clamped thereon can be adjusted, thereby facilitating the welding operation of the relevant personnel.

[0033] In this embodiment, the driving assembly 5 is installed on one side of the frame 3 and is used to drive the welding frame 4 to slide along the connecting plate 32. The driving assembly 5 includes a rotary driving member 51, a screw rod 52 and at least two third slide rails 53. The two third slide rails 53 are fixedly connected to the connecting plate 32. The welding frame 4 and the third slide rails 53 are both slidably connected. The screw rod 52 is rotatably connected between the support arms 31 and is threadedly connected to the welding frame 4. The rotary driving member 51 is installed on the frame 3 and is used to drive the screw rod 52 to rotate. The rotary driving member 51 can be a rotary motor. The rotary driving member 51 drives the screw rod 52 to rotate, so that the welding frame 4 can be driven to slide along the third slide rails 53 by the thread to adjust the position of the welding frame 4.

[0034] In this embodiment, the welding frame 4 includes an extension arm 41 that is slidably connected to the connecting plate 32, and a positioning plate 42 that is pivotally connected to the end of the extension arm 41 away from the connecting plate 32. The positioning plate 42 is located to the side of the workbench 1 and has an elongated arc-shaped hole formed in the positioning plate 42. The elongated arc-shaped hole facilitates the sliding of the positioning rod of the welding gun, thereby facilitating the height adjustment of the welding gun to better match the position of the workbench 1.

[0035] The implementation principle of the adjustable welding mechanism of the foil winding machine of this embodiment is as follows:

[0036] Before welding, an appropriate number of workbenches 1 are selected based on the shape and size of the copper busbar and copper foil and assembled together to form a corresponding welding table. The second slide rail 22 is then adjusted to rotate, thereby adjusting the rotation angle of the welding table. The copper busbar and copper foil are then mounted on the welding table and secured with the abutment assembly 2. During welding, the driving assembly 5 is used to adjust the left and right movement of the welding gun, effectively completing the welding work at the corresponding positions of the copper busbar and copper foil.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
