Technical Field

[0001] This utility model relates to the field of adhesive application technology, and more specifically, to a distributing nozzle and an adhesive application device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the safety and stability of power batteries, as core components, have attracted much attention. Battery modules generate a large amount of heat during charging and discharging. If this heat cannot be dissipated in time, it may lead to battery overheating, affecting battery safety and lifespan. To meet the safety performance requirements of battery modules and ensure stable operation of the battery pack, a low-density potting compound needs to be sprayed onto certain positive electrode areas on the surface of the battery module. This compound helps the battery effectively dissipate heat during charging and discharging, preventing overheating.

[0003] However, existing technologies suffer from low adhesive application efficiency. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0029] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0031] In existing technologies, adhesive spraying typically uses a single-hole mixing nozzle, where adhesive is sprayed directly onto the surface of the positive electrode cell through the nozzle, with only one cell hole being sprayed at a time. While this method can meet basic heat dissipation requirements, the low efficiency of applying adhesive, especially in large-scale production environments, significantly increases the time cost of spraying operations and impacts overall production efficiency.

[0032] For the above issues, please refer to... Figure 1 and Figure 2 This utility model provides a glue applicator including a glue cartridge and a distributing nozzle 100. The distributing nozzle 100 includes a connecting portion 110, a transition portion 120, and a plurality of glue-applying portions 130. One end of the transition portion 120 is connected to the connecting portion 110, and the other end is connected to the plurality of glue-applying portions 130. The connecting portion 110 is provided with a glue inlet channel 111, the transition portion 120 is provided with a receiving cavity 121, and each glue-applying portion 130 is provided with a glue outlet channel 131. By sequentially connecting the connecting portion 110, the transition portion 120, and the plurality of glue-applying portions 130, the glue inlet channel 111, the receiving cavity 121, and the plurality of glue outlet channels 131 can be sequentially connected.

[0033] Understandably, one end of the glue cartridge is provided with a glue inlet, and the other end is fitted onto the connecting part 110, thereby connecting the glue inlet channel 111 with the channel of the glue cartridge and the glue inlet. Different types of glue enter the channel of the glue cartridge, thereby forming a mixed glue, which can flow into the glue inlet channel 111 through the channel. After flowing through the glue inlet channel 111, the glue enters the receiving cavity 121, and then enters different glue outlet channels 131 through the receiving cavity 121. Since this embodiment is provided with multiple glue application parts 130, the glue application device can apply glue to multiple battery cell holes simultaneously, thereby improving the glue application efficiency.

[0034] Furthermore, because this embodiment includes a transition section 120, the adhesive does not directly enter the adhesive outlet channel 131 from the adhesive inlet channel 111. Instead, it accumulates within the receiving cavity 121 and then enters the adhesive outlet channel 131 for application. The transition section 120 buffers and distributes the adhesive, resulting in a more uniform distribution of adhesive within the multiple adhesive outlet channels 131. This prevents insufficient adhesive application in some outlet channels 131, thereby improving the adhesive application quality.

[0035] Furthermore, the flow-dividing nozzle 100 also includes a flow-dividing plate 140 connected to the inner wall of the receiving cavity 121, thereby dividing the receiving cavity 121 into multiple sub-chambers. Each sub-chamber is connected to the glue inlet channel 111 and to a glue outlet channel 131. Understandably, after the glue flows through the glue inlet channel 111, it is divided into multiple portions by the flow-dividing plate 140, thereby entering different sub-chambers and then flowing into the corresponding glue outlet channel 131.

[0036] In this embodiment, there are two adhesive application sections 130, so a flow divider 140 is provided. In other embodiments, there may be three or more adhesive application sections 130, and the number or shape of the flow divider 140 can be adjusted according to the actual situation.

[0037] In this embodiment, one end of the diversion plate 140 is connected to the center of the accommodating cavity 121, thereby making the volumes of the two sub-cavities the same, thus ensuring uniform glue distribution and consistent glue output from each glue application section 130, thereby avoiding insufficient glue application and improving glue application quality.

[0038] Based on the above, it should be noted that in this embodiment, the sidewall of the flow divider 140 abuts against the inner wall of the receiving cavity 121, meaning that the various sub-cavities are not interconnected. Since each sub-cavity is independent, mutual interference and differences in flow paths between the various sub-cavities can be avoided, which is beneficial for achieving synchronous, multi-point, and equal-volume adhesive application, improving the consistency of adhesive application; it also prevents blockages in one adhesive outlet channel from affecting other sub-cavities and the adhesive outlet channel 131.

[0039] The other end of the flow divider 140 extends toward the glue inlet channel 111 of the flow divider nozzle 100, so that at least a portion of the flow divider 140 is located in the glue outlet channel 131, that is, the other end of the flow divider 140 extends into the glue inlet channel 111, thereby pre-dividing the glue in the glue inlet channel 111 to guide the glue into different sub-chambers, so that the amount of glue in each sub-chamber is consistent, avoiding the problem of insufficient glue in some sub-chambers due to pressure difference and other reasons, and improving the uniformity of distribution.

[0040] It should be noted that the height of the portion of the distributor plate 140 located within the glue inlet channel 111 is less than the length of the glue inlet channel 111, thus leaving space for the glue cartridge to be fitted together with the distributor nozzle 100.

[0041] In this embodiment, the connection between the flow divider 140 and the inner wall of the accommodating cavity 121 is arc-shaped to facilitate the flow of adhesive and prevent adhesive from accumulating at the corner of the connection.

[0042] Further, please refer to Figure 1 and Figure 2In this embodiment, the adhesive outlet channel 131 includes a flow-promoting section 1311, a flow-retarding section 1313, and a return section 1312 connected in sequence. The flow-promoting section 1311 is connected to the receiving cavity 121. It can be understood that the adhesive in the receiving cavity 121 flows through the flow-promoting section 1311, the flow-retarding section 1313, and the return section 1312 in sequence, and finally flows out from the return section 1312, completing the adhesive application.

[0043] It should be noted that in this embodiment, the diameter of the slow flow section 1313 is larger than the diameter of the flow-promoting section 1311, so that when the glue flows from the flow-promoting section 1311 into the slow flow section 1313, the flow rate of the glue decreases, thereby making the flow rate of the glue more stable and avoiding the phenomenon of unstable glue output due to excessive flow rate, so that the glue output of each glue outlet channel 131 is consistent.

[0044] The recirculation section 1312 is located at the end of the adhesive outlet channel 131, and its cross-sectional area gradually decreases along its axial direction. Understandably, the recirculation section 1312 is conical, allowing the adhesive to gradually concentrate and be applied to the holes in the battery cell, preventing adhesive overflow. Furthermore, because the recirculation section 1312 is conical, after application, the adhesive will flow back due to negative pressure, preventing adhesive dripping from the outlet.

[0045] Based on the above, in this embodiment, the axis of each flow-promoting section 1311 is set at an angle to the axis of the glue inlet channel 111. Understandably, the glue inlet channel 111 is in a vertical state. Therefore, the flow-promoting section 1311 is inclined relative to the glue inlet channel 111, so that when the glue in the accommodating cavity 121 flows to both sides, it can flow into the flow-promoting section 1311 in a smooth manner, without colliding with the inner walls on both sides. This avoids the sudden change in the flow direction of the glue due to the impact, which would cause local resistance or eddies, and makes the flow of the glue more stable.

[0046] Furthermore, the axes of the multiple return sections 1312 are parallel to each other, so that the multiple glue outlets are located on the same plane, thereby enabling the glue to be applied smoothly to different cell holes on the battery module, thus improving the glue application efficiency.

[0047] In summary, this embodiment, by providing a connecting portion 110, a transition portion 120, and multiple adhesive application portions 130 connected in sequence, ensures that the adhesive inlet channel 111, the receiving cavity 121, and the multiple adhesive outlet channels 131 are sequentially connected. The connecting portion 110 is connected to the adhesive cartridge, allowing the adhesive in the cartridge to flow into each adhesive application portion 130. Because this embodiment has multiple adhesive application portions 130, it can simultaneously apply adhesive to different cell holes on the battery module, thereby improving adhesive application efficiency. Furthermore, this embodiment includes a transition portion 120 to ensure more uniform adhesive distribution and consistent adhesive volume within the multiple adhesive outlet channels 131, preventing insufficient adhesive application.

[0048] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
