[0002] In the assembly process of power batteries, energy storage batteries and consumer battery modules, in order to enhance the structural stability, shock resistance and insulation safety of the module, it is often necessary to apply adhesive between adjacent cells. Especially in cylindrical cell modules, structural adhesive is often injected into the gap area between the tops of the cells so that the adhesive forms a transverse connecting bridge after curing, thereby improving the overall mechanical strength and durability of the module.

[0003] Current dispensing processes mainly rely on visual positioning or simple limiting molds. Manual or automated equipment applies glue point by point along the cell array using a glue spray head. However, since there is a lot of exposed metal surface in the cell terminal area, if the glue spray is off-center, the glue amount is uneven, or it is not properly controlled, glue overflow and adhere to the surface of the positive terminal of the cell, which can lead to short circuits, corrosion, or affect electrical performance. In severe cases, it can even endanger the safety of the module. In addition, glue overflow can also contaminate the surrounding structure, increase the difficulty of cleaning and rework, and restrict the improvement of the stability and automation of the dispensing process.

[0018] In the assembly process of power batteries, energy storage batteries and consumer battery modules, in order to enhance the structural stability, shock resistance and insulation safety of the module, it is often necessary to apply adhesive between adjacent cells. Especially in cylindrical cell modules, structural adhesive is often injected into the gap area between the tops of the cells so that the adhesive forms a transverse connecting bridge after curing, thereby improving the overall mechanical strength and durability of the module.

[0019] Current dispensing processes mainly rely on visual positioning or simple limiting molds. Manual or automated equipment applies glue point by point along the cell array using a glue spray head. However, since there is a lot of exposed metal surface in the cell terminal area, if the glue spray is off-center, the glue amount is uneven, or it is not properly controlled, glue overflow and adhere to the surface of the positive terminal of the cell, which can lead to short circuits, corrosion, or affect electrical performance. In severe cases, it can even endanger the safety of the module. In addition, glue overflow can also contaminate the surrounding structure, increase the difficulty of cleaning and rework, and restrict the improvement of the stability and automation of the dispensing process.

[0020] Therefore, this utility model provides a simple, precise, and effective dispensing auxiliary fixture that can prevent glue overflow and protect the terminal post area, thereby improving the safety, consistency, and controllability of the battery module dispensing process.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0022] like Figure 1-4 The battery dispensing anti-overflow adhesive fixture shown includes a base 1 and an anti-overflow adhesive cover plate 2. The top of the base 1 is provided with a plurality of workpiece grooves 3. The bottom of the anti-overflow adhesive cover plate 2 is provided with a plurality of limiting grooves 8 that match the workpiece grooves 3. The anti-overflow adhesive cover plate 2 is provided with a plurality of injection holes 6. Each injection hole 6 is located at the corresponding position of the gap between any pair of adjacent limiting grooves 8. The injection hole 6 and its corresponding two adjacent limiting grooves 8 form a cross-groove arrangement. The inner wall of the injection hole 6 is inclined, and the cross-sectional shape of the inner cavity of the injection hole 6 is an isosceles trapezoid.

[0023] In this embodiment, multiple workpiece grooves 3 on the base 1 are used to fix individual battery cells, ensuring that the battery is in a stable position during the dispensing process. Multiple limiting grooves 8 on the anti-overflow cover 2 are used to accurately position the top of the battery. At the same time, the glue injection holes 6 on the anti-overflow cover 2 ensure that the glue is injected only into the gaps between the batteries, avoiding overflow. The anti-overflow cover 2 can be driven by a robotic arm or other automated mechanism to automatically fit the top of the base 1 and precisely cooperate with the workpiece grooves 3 and limiting grooves 8 on the base 1 to ensure that the battery is stably positioned during the dispensing process. The dispensing operation is completed by an automatic dispensing machine. The glue injection holes 6 are controlled by the dispensing machine to control the glue flow rate and evenly inject the glue into the gaps between the batteries.

[0024] In the design of the glue injection hole 6, the inner wall of the hole is inclined, and the cross-section of the inner cavity is an isosceles trapezoid. This design plays a key role in several aspects. First, the inclined design makes it difficult for the glue to adhere to the hole wall during injection, thereby reducing stringing. When the anti-overflow glue cover 2 is opened, the glue can flow naturally along the hole wall due to the inclined inner wall, avoiding excessive glue residue or stringing after the dispensing machine stops, ensuring a clean operating environment. Second, the isosceles trapezoidal cross-section shape allows the glue to maintain a uniform distribution during flow, preventing glue from accumulating or flowing back at the glue injection hole 6. This design controls the flow rate and velocity of the glue, enabling the glue to be stably and evenly applied to the gaps between the batteries, further improving the accuracy of dispensing and effectively preventing glue overflow, ensuring the stability and reliability of the dispensing process.

[0025] Multiple workpiece grooves 3 and multiple limiting grooves 8 are arranged in a matrix. The inner cavity of the workpiece groove 3 matches the shape of the battery, and the inner cavity of the limiting groove 8 matches the shape of the top surface of the battery.

[0026] In this embodiment, multiple workpiece slots 3 are arranged in a matrix to accommodate battery cells of different sizes, which can meet the dispensing requirements of batteries of different specifications. This modular design allows the fixture to quickly adapt to different types of battery assembly, improving production efficiency. The depth and width of the workpiece slots 3 are precisely calculated to maintain battery stability while avoiding battery damage caused by excessive clamping. Through the cooperation between the workpiece slots 3 and the limiting slots 8 of the anti-overflow glue cover plate 2, accurate battery positioning can be achieved, avoiding glue deviation or overflow caused by positional errors during the dispensing process.

[0027] A clearance groove 7 is provided at the center of the top of the inner wall of the limiting groove 8, which penetrates the anti-overflow cover plate 2. The clearance groove 7 matches the shape of the positive terminal post of the battery.

[0028] In this embodiment, the clearance groove 7 is matched with the shape of the positive terminal of the battery to ensure that the adhesive does not come into contact with the positive terminal of the battery during the dispensing process, thus avoiding problems such as short circuits or corrosion. This design can effectively isolate the positive terminal of the battery and ensure that the battery remains in a safe state during the dispensing process. At the same time, the clearance groove 7 also facilitates the insertion and removal of the battery, making the operation of the fixture more convenient.

[0029] The base 1 has positioning holes 4 at each of the four corners at the top, and the bottom of the anti-overflow cover plate 2 is connected to multiple positioning posts 5 that match the positioning holes 4.

[0030] In this embodiment, the cooperation between the positioning hole 4 and the positioning post 5 not only enables the anti-overflow cover plate 2 and the base 1 to be accurately aligned, avoiding dispensing errors caused by positional deviations, but also enhances the overall stability of the fixture. During the dispensing process, the anti-overflow cover plate 2 can be firmly fixed on the base 1, preventing displacement or loosening between the cover plate 2 and the base 1, and ensuring the accuracy and consistency of the dispensing process.

[0031] Multiple rubber rings 9 are embedded and connected at the bottom of the anti-overflow glue cover plate 2. The rubber rings 9 are arranged around the glue injection hole 6, and the lower surface of the rubber rings 9 is arranged along the inner wall of the limiting groove 8 and the lower surface of the anti-overflow glue cover plate 2.

[0032] In this embodiment, the rubber ring 9 can not only effectively prevent glue leakage, but also further enhance the sealing between the anti-overflow glue cover plate 2 and the base 1, ensuring that the glue flow is controlled during the dispensing process and preventing the glue from flowing back or overflowing after dispensing. Through this design, glue waste is reduced, cleaning costs are lowered, and the efficiency and reliability of dispensing are improved.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
