Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a battery cell nickel sheet welding and pressing device. Background Technology

[0002] The nickel sheet welding and clamping device is a key piece of equipment in the production of power batteries. Its core function is to ensure that the nickel sheet and the cell terminal are in close contact during the welding process through mechanical clamping, thereby solving welding defects such as incomplete welding and bulging caused by the softness and easy deformation of the nickel sheet.

[0003] Existing nickel sheet welding and pressing devices for battery cells can only press nickel sheets in fixed positions, and cannot be applied to the welding and pressing of nickel sheets of various sizes, which greatly reduces the scope of application. Therefore, it is necessary to provide a nickel sheet welding and pressing device for battery cells to solve the above-mentioned technical problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To overcome the shortcomings of existing technologies, a battery cell nickel sheet welding and pressing device is proposed to solve the problem that existing battery cell nickel sheet welding and pressing devices can only press the nickel sheets in a fixed position, and cannot be applied to the welding and pressing of battery cell nickel sheets of various sizes, thus greatly reducing the scope of application.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a battery cell nickel sheet welding and pressing device, including a base and a battery support platform fixedly installed on the top of the base. A column is also fixedly installed on one side of the top of the base. A lifting column is slidably installed inside the column, and an electric push rod is fixedly installed at the bottom of the inner cavity of the column. The output end of the electric push rod is fixedly connected to the bottom of the lifting column. A welding and pressing mechanism for pressing the battery cell nickel sheet is also provided at the top of the lifting column.

[0008] Furthermore, the welding clamping mechanism includes a clamping frame and T-shaped grooves on both sides of the bottom of the clamping frame. An avoidance groove communicating with the T-shaped groove is also provided on the outer wall of the clamping frame.

[0010] Furthermore, the clamping assembly includes a clamping plate and T-shaped sliders fixedly disposed on both sides of the top of the clamping plate. The two T-shaped sliders are respectively slidably disposed in T-shaped grooves at corresponding positions. The top of the clamping plate is also provided with a welding clearance groove for exposing the nickel sheet of the battery cell so that the welding torch can perform welding.

[0011] Furthermore, a rubber protective plate is fixedly installed at the bottom of the clamping plate, and one of the T-shaped sliders and the clamping frame are locked together by a locking knob.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model has the following advantages: By setting multiple clamping components on the clamping frame, the distance between two adjacent clamping components can be flexibly and precisely adjusted with reference to the scale groove, so that each clamping component can be positioned directly above the nickel sheet of the battery cell, which facilitates subsequent welding and clamping operations. Furthermore, by flexibly adjusting the distance between two adjacent clamping components, it can be applied to clamping work of nickel sheets of battery cells with different spacings, greatly improving the applicability. After the rubber protective plate contacts the nickel sheet of the battery cell, it can be stably clamped and avoid damage to the nickel sheet. Driven by the electric push rod, the height of the clamping frame can be controlled to achieve the purpose of synchronously controlling the height of multiple clamping components, thereby simultaneously completing the clamping operation of multiple nickel sheets of battery cells.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figures 1 to 5 A battery cell nickel sheet welding and pressing device includes a base 1 and a battery support platform 2 fixedly installed on the top of the base 1. A column 3 is also fixedly installed on one side of the top of the base 1. A lifting column 4 is slidably installed inside the column 3. An electric push rod 5 is also fixedly installed at the bottom of the inner cavity of the column 3. The output end of the electric push rod 5 is fixedly connected to the bottom of the lifting column 4. A welding and pressing mechanism for pressing the battery cell nickel sheet is also provided at the top of the lifting column 4. The initial height of the bottom of the welding and pressing mechanism is higher than the height of the battery cell.

[0022] Multiple clamping components 9 are installed on the clamping frame 6. Using the graduated grooves 10 on them, the operator can easily and accurately adjust the spacing between two adjacent clamping components 9. After such adjustment, each clamping component 9 can be precisely positioned directly above the nickel sheet of the battery cell.

[0023] In this embodiment, the welding clamping mechanism includes a clamping frame 6 and T-shaped grooves 7 formed on both sides of the bottom of the clamping frame 6. An avoidance groove 8 connected to the T-shaped grooves 7 is also formed on the outer wall of the clamping frame 6.

[0024] Because the spacing between adjacent clamping components 9 can be flexibly adjusted, this device can well adapt to clamping tasks of nickel sheets in battery cells with different spacing specifications, significantly improving its applicability and versatility. When the rubber protective plate 94 comes into contact with the nickel sheet in the battery cell, it can achieve a stable and reliable clamping effect without causing pressure damage to the nickel sheet.

[0025] In this embodiment, multiple clamping components 9 are movably arranged inside the two T-shaped slides 7, and scale grooves 10 for marking the positions of the clamping components 9 are provided on the side wall of the clamping frame 6.

[0026] Driven by the electric push rod 5, the height of the clamping frame 6 can be effectively controlled. In this way, the height of multiple clamping components 9 can be adjusted simultaneously, thereby completing the clamping operation of multiple nickel sheets in one go, improving work efficiency.

[0027] In this embodiment, the clamping assembly 9 includes a clamping plate 91 and T-shaped sliders 92 fixedly disposed on both sides of the top of the clamping plate 91. The two T-shaped sliders 92 are respectively slidably disposed in T-shaped grooves 7 at corresponding positions. The top of the clamping plate 91 is also provided with a welding clearance groove 93 for exposing the nickel sheet of the battery cell so that the welding torch can perform welding. The nickel sheet of the battery cell needs to be straightened before welding, and the nickel sheet of the battery cell needs to be laid flat on the battery cell.

[0028] In this embodiment, a rubber protective plate 94 is also fixedly installed at the bottom of the clamping plate 91, and one of the T-shaped sliders 92 and the clamping frame 6 are locked together by a locking knob 95.

[0029] Working principle: In use, multiple clamping components 9 are set on the clamping frame 6. The spacing between two adjacent clamping components 9 can be flexibly and precisely adjusted with reference to the scale groove 10, so that each clamping component 9 is exactly above the nickel sheet of the battery cell, which facilitates the subsequent welding and clamping operation. By flexibly adjusting the spacing between two adjacent clamping components 9, it can be used for clamping nickel sheets of battery cells with different spacing, which greatly improves the applicability. After the rubber protective plate 94 contacts the nickel sheet of the battery cell, it can be stably clamped and avoid damage to the nickel sheet. Driven by the electric push rod 5, the height of the clamping frame 6 can be controlled to achieve the purpose of synchronously controlling the height of multiple clamping components 9, thereby completing the clamping operation of multiple nickel sheets of battery cells simultaneously.
