Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a battery welding fixture. Background Technology

[0002] Currently, in the battery welding process, operators manually stack individual battery modules according to specifications, align them, and then place them into welding fixtures. Structural adhesive is then applied to both sides of the module for temporary positioning, followed by pre-pressing and clamping. After initial fixation, the tabs are batch-welded using automatic or semi-automatic welding equipment via laser or ultrasonic welding. After welding, the process proceeds to inspection, curing, and subsequent assembly.

[0003] The current welding preparation stage relies on manual stacking of battery modules and application of adhesive to side panels, a cumbersome process with poor consistency, resulting in limited production cycle time. Furthermore, bonding and fixing the side panels before welding increases the possibility of positioning errors. These issues reduce production efficiency, increase labor costs, and complicate yield control. To achieve an efficient and precise module welding process, there is an urgent need to develop a new type of battery welding fixture that integrates stacking, positioning, adhesive application, and welding. Utility Model Content

The support plates are set as L-shaped plate structures, and the two sides of the side plates abut against the upper part of the sliding grooves through the support plates. A pair of snap-fit ​​seats are fixedly connected to the inner side of the side plates, and the snap-fit ​​seats are provided with through grooves.

[0006] As a further improvement of this utility model, a rotating shaft is fixedly connected to the top of the platform, and a fitting sleeve is fixedly connected to the top of the rotating shaft. The fitting sleeve has a through hole for inserting a welding gun.

[0007] As a further improvement of this utility model, two connecting plates are fixedly connected to the bottom of the frame, and a soft pad is fixedly connected to the top of the connecting plates.

[0008] As a further improvement of this utility model, a suspension arm is fixedly connected to the top of the frame, and a suspension hole groove is opened at the top of the suspension arm.

[0009] As a further improvement of this utility model, the assembly bottom shell is configured as a rectangular frame structure, and a plurality of protrusions for the battery pack to abut against are fixedly connected to the bottom edge.

[0010] As a further improvement of this utility model, the frame body has abutting side grooves on both sides inside, and the top two sides of the assembly bottom shell are fitted and abutted with the frame body through the abutting side grooves.

[0011] The beneficial effects of this utility model are as follows: The assembly base adopts a rectangular frame structure, which, in conjunction with the protrusions, enables rapid assembly of the battery module and facilitates combination and placement. The sliding adjustment structure of the sliding groove and side plate can be flexibly adjusted according to the welding point height of different battery modules, improving the compatibility between the battery pack and the side plate to be welded.

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides a battery welding fixture, including a frame 1;

[0021] As attached Figure 1 , 2 As shown in Figure 3, the frame 1 serves as the basic structure for overall support and positioning. A pair of bases 7 are fixedly connected to each of its two sides. A rotating shaft is installed on the top of each base 7, and a fitting sleeve 8 is connected to the top of the rotating shaft. The fitting sleeve 8 has a through hole for positioning the welding gun, facilitating precise placement of the welding tool. The angle of the fitting sleeve 8 can be adjusted via the rotating shaft on the top of the base 7, improving welding accuracy and work efficiency. Inside the frame 1 is a detachable assembly base shell 2. The assembly base shell 2 adopts a rectangular frame structure, possessing excellent support and positioning capabilities. Multiple protrusions 11 are evenly distributed along its bottom edge to limit the position of the battery module, enabling rapid centering and initial positioning. To prevent damage to the bottom of the module caused by high-temperature welding, two connecting plates are installed at the bottom of the frame 1. A flexible cushioning pad 9 is fixed to the top of the connecting plates. The pad 9 is made of heat-resistant, high-elastic material, preferably fluororubber, to improve safety and adaptability.

[0022] As attached Figure 1 , 3 As shown in Figure 4, in order to enable the tooling to be used in a suspended manner, the top of the frame 1 is provided with a suspension arm 10, the top of which is provided with a suspension hole slot for hoisting, so that the tooling can be integrated with the automated welding system and improve space utilization. The two sides inside the frame 1 are provided with abutment side grooves 12 for fitting and connecting with the side of the top of the assembly base 2.

[0023] As attached Figure 1 , 2As shown, regarding the positioning of the side plate to be welded, sliding grooves 3 are fixedly installed on both sides of the frame 1, and adjustable side plates 4 are provided inside the grooves 3. The side plates 4 can be slidably adjusted according to different module heights. Multiple screw holes are provided through both sides, and they are connected to the support plate 5 by bolts. The support plate 5 adopts an L-shaped structure to provide stable lateral support, so that the side plate 4 can be firmly positioned above the sliding grooves 3, ensuring the lateral stability of the battery module. A pair of snap-fit ​​seats 6 are fixedly connected to the inner side of the side plate 4. The snap-fit ​​seats 6 have through grooves, which can be used for temporary suspension, facilitating subsequent welding, reducing reliance on manual positioning, and achieving precise and quick pre-welding preparation.

[0024] Working Principle: In practical implementation, the operator first places the battery module into the assembly base 2. The bottom of the module is supported by several protrusions 11. The side plates 4 are connected and assembled with the frame 1 through the abutment side grooves 12 on both sides. By adjusting the side plates 4 in the sliding groove 3, the side plates 4 are slid to a suitable height position according to the height of the battery module and the side plates to be welded, and then fixed with bolts through the support plate 5. Since the side plate 4 has a snap-fit ​​seat 6 on the inner side for temporarily suspending the structural adhesive side plate to be welded, the welding gun is inserted through the sleeve hole of the fitting sleeve 8, and the fitting sleeve 8 can be angled around the rotation axis on the platform 7, making the welding angle more flexible and precise. At the same time, the top of the suspension arm 10 has a suspension hole groove, which can suspend the tooling for quick connection of subsequent processes such as painting and quality inspection, and can be adapted to the working environment of the assembly line.
