When welding the battery cells, professional clamps are generally used to lock the battery cell positions. However, there are certain problems in actual use. Specifically, although the clamp can lock the battery cell position when in use, it cannot assist in welding the electrode sheets to the battery cell electrodes, which affects the positioning effect and practical effect of the equipment itself.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0026] Depend on Figure 1 and Figure 2 As shown, it is a structural diagram of the battery cell welding fixture in this embodiment, including a mounting base 1, a workbench 2, a battery cell assembly 3 and a clamping block 4. The workbench 2 is installed on the surface of the mounting base 1, and the battery cell assembly 3 is arranged on the surface of the workbench 2. Clamping blocks 4 for clamping the battery cell assembly 3 are installed on both sides of the battery cell assembly 3. There are two groups of clamping blocks 4. The end of the clamping block 4 is installed with a clamping mechanism 6 for adjusting the position of the clamping block 4 itself, and the side of the clamping block 4 is installed with an auxiliary mechanism 5.

[0027] During use, the device is placed at the target position, and then the battery cell assembly 3 to be welded is placed on the upper surface of the workbench 2. The position of the clamping block 4 itself is moved through the operation of the clamping mechanism 6, and the battery cell assembly 3 as a whole is clamped and fixed by the clamping block 4. In conjunction with the auxiliary mechanism 5 installed on the outside of the clamping block 4, the subsequent welding of the electrode sheet and the battery cell is more stable and accurate, ensuring the stability of the equipment during operation.

[0028] By the attached Figure 3 As shown, it is a structural schematic diagram of the clamping mechanism 6 in this embodiment, the clamping mechanism 6 includes an outer shell 61, an electric push rod 62 and an extrusion rod 63, the outer shell 61 is fixedly mounted on the upper surface of the workbench 2, the electric push rod 62 is mounted inside the outer shell 61, the extrusion rod 63 is fixedly mounted at the output end of the electric push rod 62, and the extrusion rod 63 is connected to the end of the clamping block 4.

[0029] During use, the electric push rod 62 itself pushes the extrusion rod 63 to move sideways. At this time, the distance between the two groups of clamping blocks 4 changes. The two groups of clamping blocks 4 clamp and position the battery cell assembly 3 at the middle end to ensure the stability of the battery cell assembly 3 during the subsequent welding process.

[0030] By the attached Figure 3 As shown, it is a structural diagram of the clamping mechanism 6 in this embodiment. The clamping mechanism 6 also includes a controller 64, which is installed on the upper surface of the workbench 2. The controller 64 is electrically connected to the electric push rod 62. A plurality of control buttons are installed on the surface of the controller 64. During use, through the installation and use of the controller 64, the spacing of the movement of the output end of the electric push rod 62 itself can be flexibly and accurately adjusted, so that the clamping block 4 can accurately clamp and position the battery cell assembly 3, and the setting of multiple groups of control buttons makes the control of the electric push rod 62 itself more convenient.

[0031] By the attached Figure 4 As shown, it is a structural schematic diagram of the auxiliary mechanism 5 in this embodiment, the auxiliary mechanism 5 includes a limit slider 51, a first telescopic rod 52, a second telescopic rod 53 and an alignment component 54, the limit slider 51 is slidably installed inside the clamping block 4, the first telescopic rod 52 is fixedly installed on the side of the limit slider 51, the second telescopic rod 53 is installed at the output end of the first telescopic rod 52, and the alignment component 54 is fixedly installed at the output end of the second telescopic rod 53.

[0032] During use, the auxiliary mechanism 5 of corresponding size is selected according to the overall specifications and quantity of the battery cell assembly 3, and then the limit slider 51 is slid into the clamping block 4. Through the cooperation of the first telescopic rod 52 and the second telescopic rod 53, the horizontal position and vertical height of the alignment assembly 54 are flexibly adjusted to facilitate the alignment assembly 54 to position the output end of the battery cell and the electrode sheet, thereby assisting the subsequent electrode sheets to be stably welded.

[0033] By the attached Figure 5 As shown, it is a structural diagram of the alignment component 54 in this embodiment, and the alignment component 54 includes a supporting plate 541 and a limiting plate 542. The supporting plate 541 is fixedly installed at the output end of the second telescopic rod 53, and the limiting plate 542 is fixedly installed on the side of the supporting plate 541. A plurality of limiting grooves 543 for cooperating with the positioning of the electrode sheet are provided inside the limiting plate 542.

[0034] During use, the electrode sheet to be welded is placed on the surface of the limiting plate 542. The position of the electrode sheet is locked and reinforced by using the limiting groove 543. Then, the first telescopic rod 52 and the second telescopic rod 53 are moved to move the electrode sheet to the target position, so that the electrode sheet is aligned with the electrode of the battery cell to assist in the subsequent welding of the electrode sheet and the battery cell.

[0035] By the attached Figure 5 As shown, there are multiple groups of limit grooves 543, and the depth of each group of limit grooves 543 is different. During use, the limit grooves 543 of corresponding depth are selected according to the height and specifications of the battery cells themselves, and the electrode sheets are installed in the corresponding limit grooves 543 to assist the battery cells in welding.

[0037] During use, the cylinder 12 is used to flexibly adjust the distance between the base 11 and the workbench 2. When the base 11 is stably placed on the ground, the workbench 2 can be adjusted to a position suitable for the user's height, making it easier for the user to perform welding operations during subsequent welding.

[0038] By the attached Figure 6 As shown, it is a structural diagram of the mounting base 1 in this embodiment.
