Description

Technical Field

[0001] This utility model relates to a coating device, and more particularly to a cylindrical battery PACK series coating device. Background Technology

[0002] Large cylindrical power battery packs are liquid-cooled on one or both sides, with serpentine liquid cooling plates used between the cells. After the battery modules are placed in the pack box, they need to be coated with expanding foam. During trial production, the foam is manually applied to the battery packs using measuring cups at pre-planned locations. The disadvantages of manual glue application are: (1) When applying glue manually, the glue between the battery cells is blocked by the liquid cooling plate due to its position, resulting in poor glue flow and even poor glue leveling height consistency. That is, the height between the battery cell and the housing is greater than the height between the battery cells, which may result in insufficient adhesive strength in the middle part, causing product failure; (2) Due to the operation method, the glue between the battery cells is blocked by the liquid cooling plate, and glue residue remains on the liquid cooling plate or the outer wall of the battery cell, resulting in glue waste; (3) When applying foaming glue, for large-sized PACK products, due to the short foaming time, when applying glue to one side of the product, the other side has already foamed, which may result in poor foaming; (4) When applying glue manually, if the glue is accidentally applied to the product, a special person is required to clean up the residual glue, which consumes a lot of manpower, material resources and time.

[0003] Therefore, it is necessary to develop corresponding tooling for the glue coating process. Utility Model Content

[0004] To address the drawbacks of manual adhesive coating, this solution provides a cylindrical battery PACK series adhesive coating device.

[0005] A cylindrical battery PACK series adhesive coating device includes a mounting plate and a funnel body; the funnel body is fixedly connected to the mounting plate, and the funnel body is divided into a flange, an inclined portion and a protruding portion in the height direction. The inner cavity of the inclined portion gradually narrows from one end near the flange to one end near the protruding portion, and a curved adhesive outlet is provided at the bottom of the protruding portion.

[0006] Preferably, the glue outlet is wavy, and the inner cavity of the funnel body has a shape that matches the shape of the glue outlet.

[0007] Preferably, the mounting plate is provided with a glue-leaking groove, the funnel body is connected to the glue-leaking groove, and the funnel bodies are arranged in an array along the length direction of the glue-leaking groove.

[0008] Preferably, the mounting plate is provided with at least two glue-draining grooves, and the two glue-draining grooves are arranged in parallel.

[0009] Preferably, the inner cavity of the glue-leaching tank is inclined, and a positioning groove matching the inclined part is provided on the bottom surface of the glue-leaching tank. The flange of the funnel body is connected to the small end of the glue-leaching tank. The funnel body passes through the positioning groove to the other side of the mounting plate.

[0010] Preferably, one side of the mounting plate is provided with a pole positioning hole for positioning.

[0011] This utility model has at least the following technical effects; (1) Regarding the spacing between battery cells, the series funnel body can penetrate deep into the middle of the battery cells, and the penetration length is lower than the upper surface of the liquid cooling plate, without contacting the surface of the battery cells and the liquid cooling plate, reducing glue residue and improving glue utilization.

[0012] (2) A glue-spraying groove covers several funnel bodies, and the funnel bodies are evenly distributed in the corresponding positions of the liquid-cooled cylindrical power battery PACK, ensuring that the glue amount around the battery PACK and in the middle is evenly distributed, thereby ensuring the glue thickness between the battery PACK cells and ensuring the adhesive mechanical strength of the battery PACK product; at the same time, glue only needs to be sprayed into the flow channel groove when spraying glue, which greatly improves the glue spraying efficiency.

[0013] (3) By adjusting the size of the device and the funnel body, structural adhesive or foam adhesive can be applied to liquid-cooled cylindrical power battery PACKs of different sizes (length, width and height). Attached Figure Description

[0016] The following is in conjunction with the embodiments and appendices Figure 1 To be continued Figure 6The principles and features of this utility model are described; the examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] A cylindrical battery PACK series coating device includes a mounting plate 100 and a funnel body 200.

[0018] The mounting plate 100 is a thin plate that can be customized according to the dimensions of the cylindrical battery pack. For ease of description, one side of the mounting plate 100 is defined as side A, and the other side parallel to it is defined as side B. Three (or more) adhesive leakage grooves 101 are provided on side A of the mounting plate 100. The three (or more) adhesive leakage grooves 101 are arranged in parallel, and the spacing between two adjacent adhesive leakage grooves 101 is the same as that between two rows of adjacent cells in the cylindrical battery pack. The inner cavity of the adhesive leakage groove 101 is inclined, and the width of the adhesive leakage groove 101 gradually decreases from the side of the mounting plate 100 closer to side A to the side closer to side B. A positioning groove 103 is provided on the bottom surface of the adhesive leakage groove 101.

[0019] Define the height direction of the funnel body 200 as the X direction, and define the length direction of the funnel body 200 as the Y direction, as shown in the attached figure. Figure 5 As shown, the funnel body 200 is divided into a flange portion 201, an inclined portion 202, and a protruding portion 203 in its height direction. The funnel body 200 is integrally formed, and the inner cavity of the inclined portion 202 gradually narrows from the end near the flange portion 201 to the end near the protruding portion 203. The inner cavities of the inclined portion 202 and the protruding portion 203 are wavy in their length direction. A through-hole glue outlet 204 is provided at the bottom of the protruding portion 203, and the glue outlet 204 is also wavy.

[0020] The funnel body 200 can be fixed to the mounting plate 100 by adhesive. Specifically, each glue-leaching groove 101 is connected to multiple funnel bodies 200, which are arranged in an array along the length of the glue-leaching groove 101. The flange portion 201 overlaps the bottom surface of the glue-leaching groove 101, the shape of the inclined portion 202 matches the inner cavity shape of the positioning groove 103, and the protrusion 203 passes through the positioning groove 103 to the B side of the mounting plate 100. A terminal positioning hole 102 is provided on the B side of the mounting plate 100, which cooperates with the terminal of the cylindrical battery PACK cell to fix the device.

[0021] Before applying the adhesive, place the device on the battery module to be coated. Simply insert the series-connected adhesive applicator into the gap between the cells; precise positioning is not required. Pour the adhesive into the flow channel, where it flows in automatically under gravity.
