[0002] As the most critical part in new energy projects, the waterproof and insulation problems of battery packs are particularly important. At present, during the production and processing of battery packs, potting glue needs to be applied to the end plates of the battery packs to play an insulating and protective role. However, the potting gap of the battery pack is generally small, which makes it difficult for the glue coating head to reach into the gap for glue application. Moreover, there is air in the gap, and the flow rate of the poured glue is not enough to expel the air in the gap, resulting in the generation of bubbles, thus affecting the performance of the product. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a glue coating head and a glue coating device.

[0004] In a first aspect, an embodiment of the present application provides a glue coating head, including:

The isolation column is used for splitting the glue entering the inside of the first glue nozzle main body;

[0007] Wherein, an arc-shaped opening communicating with the outlet for glue is provided at the outer edge of one end of the first glue nozzle main body away from the second glue nozzle main body, and the arc-shaped opening (20) is curved in an arc shape towards the inside of the first glue nozzle main body (11).

[0008] In an embodiment, the width of the outlet for glue is greater than the width of the inlet for glue.

The first nozzle body is connected to one end of the arc section away from the vertical section, and the vertical section is used to connect to a fixed glue outlet head.

[0012] In one embodiment, the length of the vertical section is between 10 mm and 15 mm.

Therefore, it should not be construed as a limitation to the present utility model.

[0029] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0030] Please refer to Figures 1 to 6 , an embodiment of the present application provides a glue - applying head A, which includes a body 10 of the glue - discharging nozzle and an isolation column 30. The body 10 of the glue - discharging nozzle includes a first glue - nozzle body 11 and a second glue - nozzle body 12 that are internally connected to each other. The first glue - nozzle body 11 is flat - shaped. One end of the second glue - nozzle body 12 away from the first glue - nozzle body 11 is provided with a glue - inlet port 12a, and one end of the first glue - nozzle body 11 away from the second glue - nozzle body 12 is provided with a glue - discharging port 11a. The isolation column 30 is arranged in the middle area inside the first glue - nozzle body 11 along the extension direction of the first glue - nozzle body 11, and the two side edges of the isolation column 30 are respectively connected to the two opposite inner walls of the first glue - nozzle body 11. The isolation column 30 is used to divide the glue entering the inside of the first glue - nozzle body 11. Among them, the outer edge of one end of the first glue - nozzle body 11 away from the second glue - nozzle body 12 is provided with an arc - shaped opening 20 communicating with the glue - discharging port 11a, and the arc - shaped opening 20 is curved in an arc shape towards the inside of the first glue - nozzle body 11.

[0031] Exemplarily, the glue outlet body 10 can be made of plastic material, so that the manufactured glue outlet body 10 has a certain deformation and can be restored after being squeezed, without affecting subsequent use. However, it should be noted that the glue outlet body 10 made of the plastic material used also needs to ensure a certain strength to prevent it from being squeezed due to insufficient strength during the process of the glue outlet body 10 extending into the gap, resulting in the extrusion and reduction of the glue outlet 11a of the glue outlet body 10 and affecting the glue outlet speed. Therefore, the specific plastic material used can be determined according to the actual situation, and no limitation is made in this regard.

[0032] Exemplarily, the first glue nozzle body 11 and the second glue nozzle body 12 can be formed into the glue outlet body 10 by injection molding, so that there is no gap at the connection between the first glue nozzle body 11 and the second glue nozzle body 12, ensuring that the glue does not leak out from the connection between the first glue nozzle body 11 and the second glue nozzle body 12 during the process of flowing from the glue inlet 12a to the glue outlet 11a.

[0033] It should be noted that the first glue nozzle body 11 is set to be flat to facilitate extending into a narrow gap. Compared with the traditional circular setting, it can be applied to a wider glue application range. At the same time, the flat first glue nozzle body 11 can adjust the width of the glue outlet 11a to obtain an appropriate glue coating width. In this way, on the premise of ensuring the process requirements, a larger glue coating width can be obtained, the area of glue coating in a single stroke can be increased, the number of reciprocating motions of glue coating can be reduced, and the glue coating efficiency is improved.

[0034] Exemplarily, the glue enters the second glue nozzle body 12 from the glue inlet 12a and flows into the first glue nozzle body 11. Since the isolation column 30 is arranged in the middle area inside the first glue nozzle body 11, the glue flowing into the first glue nozzle body 11 is shunted, so as to ensure that the glue outlet speeds in all directions of the glue outlet 11a are consistent and improve the uniformity of glue outlet. At the same time, the setting of the isolation column 30 can also play a certain supporting role, so that the first glue nozzle body 11 is not easily deformed after being squeezed, which is beneficial to improving the strength of the first glue nozzle body 11.

[0035] Exemplarily, according to fluidics, the glue outlet speeds on both sides of the glue outlet 11a will be lower than the glue outlet speed in the middle, resulting in a glue outlet speed difference. Furthermore, air will enter the glue outlet body 10, leading to the generation of bubbles. For this reason, in this embodiment, an arc-shaped port 20 communicating with the glue outlet 11a is arranged on the outer edge of the first glue nozzle body 11, and the arc-shaped port 20 is curved in an arc shape towards the inside of the first glue nozzle body 11, so as to reduce the glue flow travel on both sides of the glue outlet 11a, and further shorten the glue outlet speed difference between both sides and the middle of the glue outlet 11a, thereby effectively reducing the generation of bubbles.

[0036] The glue - applying head based on the above - mentioned technical features is provided with an arc - shaped opening 20 communicated with the glue outlet 11a along the outer edge of the first glue - nozzle body 11, so as to reduce the glue - flowing travel on both sides of the glue outlet 11a, shorten the glue - discharging speed difference between both sides and the middle of the glue outlet 11a, and achieve the purpose of reducing the generation of bubbles. At the same time, a separation column 30 is arranged in the middle area inside the first glue - nozzle body 11, so that the glue flowing into the first glue - nozzle body 11 is shunted, thereby ensuring that the glue - discharging speeds in all directions of the glue outlet 11a are consistent and improving the uniformity of glue discharging.

[0037] In one embodiment, the width of the glue outlet 11a is greater than the width of the glue inlet 12a.

[0038] Exemplarily, setting the width of the glue outlet 11a to be greater than the width of the glue inlet 12a is to evenly disperse the glue, obtain a larger glue - applying width, increase the area of glue - applying in a single stroke, reduce the number of reciprocating movements of glue - applying, and improve the glue - applying efficiency.

[0039] In one embodiment, the width of the inner cavity cross - section defined by the first glue - nozzle body 11 gradually increases in the direction away from the second glue - nozzle body 12.

[0040] Exemplarily, when the glue enters the inside of the second glue - nozzle body 12 from the glue inlet 12a and flows towards the first glue - nozzle body 11, since the width of the inner cavity cross - section defined by the first glue - nozzle body 11 gradually increases in the direction of the second glue - nozzle body 12, the glue gradually disperses during the process of flowing towards the glue outlet 11a, so as to achieve a larger glue - applying width, reduce the number of reciprocating movements of glue - applying, and improve the glue - applying efficiency.

[0041] In one embodiment, the wall thickness of the first glue - nozzle body 11 gradually decreases in the direction away from the second glue - nozzle body 12. In this way, the glue can gradually disperse during the process of flowing towards the glue outlet 11a, which is beneficial to improving the uniformity of glue discharging.

[0042] In one embodiment, the second glue - nozzle body 12 is gradually bent downward along the glue - discharging direction from the end provided with the glue inlet 12a. The second glue - nozzle body 12 includes a vertical section 122 and an arc section 121. The first glue - nozzle body 11 is connected to the end of the arc section 121 far from the vertical section 122, and the vertical section 122 is used for connecting with the fixed glue - applying head.

[0043] Exemplarily, setting the cross-section of the second nozzle body 12 as an arc structure can reduce the resistance of the glue during the flow to the glue outlet 11a, and can also increase the path of the glue in the middle of the nozzle body 10, ensuring the same flow rate as the glue on both sides. In addition, it should be noted that the way of connecting the fixed glue outlet head to the vertical section 122 can adopt the plug-in method, that is: inserting one end of the fixed glue outlet head into the vertical section 122 to realize the detachable connection between the fixed glue outlet head and the second nozzle body 12, which is convenient for subsequent replacement of the glue application head.

[0044] In one embodiment, the length of the vertical section 122 is between 10 mm and 15 mm. Based on setting the length of the vertical section 122 within the above range, it is to allow the end of the fixed glue outlet head to be inserted with sufficient length to avoid falling off during use and affecting the normal glue application work.

[0045] In one embodiment, the inner diameter of the arc section 121 gradually increases in the direction close to the first nozzle body 11. In this way, after the end of the fixed glue outlet head is inserted into the inside of the arc section 121, the connection of the fixed glue outlet head is more firm, and it can effectively avoid the separation of the glue application head and the fixed glue outlet head during the glue application process.

[0046] In one embodiment, at one end of the first nozzle body 11 away from the second nozzle body 12, a first extension edge 40 and a second extension edge 50 extend respectively along the extension direction of the first nozzle body 11, and the first extension edge 40 and the second extension edge 50 define a flow channel 60 communicating with the glue outlet 11a. Among them, the length of the first extension edge 40 is greater than the length of the second extension edge 50.

[0047] Exemplarily, the flow channel 60 communicating with the glue outlet 11a is defined by the first extension edge 40 and the second extension edge 50, so that after the nozzle body 10 can be extended into the gap, the glue flows from the glue outlet 11a to the flow channel 60, and then flows into the gap through the flow channel 60, playing a role in guiding the glue to fall into the gap.

[0048] In one embodiment, the end of the first extension edge 40 away from the second nozzle body 12 is arc-shaped.

[0049] The embodiment of the present disclosure also provides a glue application device, including the glue application head A in the above embodiment.

[0050] According to the glue application device of the embodiment of the present disclosure, adopting the above glue application head A, the technical effects are the same as those of the above glue application head A, and will not be elaborated here.

[0051] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
