Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a symmetrical dual-outlet coating head, coating device and battery production equipment. Background Technology

[0002] During the processing of battery cells, adhesive needs to be applied to the skirt edge. Currently, the adhesive inlet and outlet of the adhesive applicator are usually set up vertically. After the adhesive enters from the inlet, it flows from top to bottom until it flows out from the outlet. Because adhesive needs to be applied to both sides of the battery cell skirt during the skirt coating process, the applicator head needs to have at least two outlets at different heights in the vertical direction. During adhesive flow, the first outlet, which is higher in the vertical direction, will dispense adhesive first, resulting in inconsistent adhesive dispensing amounts between the two outlets. This can easily lead to overflow or leakage of adhesive, affecting the coating quality. In addition, the flow channel in the above method is vertically set. Due to gravity, the adhesive in the vertical flow channel will have a pressure difference between the upper and lower outlets. The adhesive near the lower outlet is subjected to the pressure of the liquid column above, so the actual dispensing pressure will be greater than that of the upper outlet. This will cause inconsistent dispensing pressure between the two outlets. Furthermore, the amount of adhesive dispensed during the coating process will gradually decrease as the amount of adhesive in the flow channel decreases, ultimately resulting in uneven coating of the skirt, or even missed coating or adhesive piling, which seriously affects the coating quality. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a symmetrical dual-outlet coating head, coating device and battery production equipment to solve the problems existing in the background art.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] In a first aspect, this utility model provides a symmetrical dual-outlet glue applicator, comprising: a glue flow section, wherein the glue flow section is provided with a horizontal flow channel; and a glue outlet groove, located at the end of the glue flow section, wherein the glue outlet groove has two symmetrical glue outlets; wherein, two symmetrical glue outlet channels are provided between the flow channel and the glue outlet groove, and the glue flowing out through the flow channel is guided to the two glue outlets respectively through the two glue outlet channels.

[0006] In the above solution, during the adhesive application process, the skirt of the battery cell is horizontally inserted into the adhesive outlet. The adhesive then flows through a horizontally designed channel, and two adhesive outlets divide the adhesive flowing out of the channel into two symmetrically arranged outlets to apply adhesive to both sides of the skirt. The symmetrical arrangement of the two adhesive outlets and outlets, along with the identical flow paths, ensures consistent adhesive dispensing from both outlets. Compared to the existing technology that uses two outlets at different heights, this solution effectively balances the amount of adhesive on both sides of the battery cell skirt, reduces adhesive overflow and leakage, and significantly improves the adhesive application quality.

[0007] Furthermore, the two glue outlets are symmetrical about the horizontal plane, and the two glue outlet channels are symmetrical about the horizontal plane.

[0008] In the above scheme, both the glue outlet and the glue channel are symmetrical about the horizontal plane to ensure that the glue flow path is the same and that the glue output and flow rate of the two glue outlets are the same.

[0009] Furthermore, the glue dispensing section is also provided with a transfer chamber, which is located between the flow channel and the glue outlet channel, and the transfer chamber is connected to the flow channel and the glue outlet channel.

[0010] Furthermore, the inner wall of the dispensing groove is a curved surface with an arc.

[0011] In the above solution, the curved inner wall allows the adhesive to flow more smoothly and fill the dispensing tank after flowing out of the dispensing port. At the same time, the curved design can avoid dead corners, thus reducing the difficulty of cleaning.

[0012] Furthermore, it also includes a glue inlet, which has a glue inlet for glue liquid to enter, and a glue inlet channel connected to the glue inlet, which is connected to the flow channel.

[0013] In the above scheme, the glue inlet is used to connect with the component that provides the glue so that the glue can enter the glue applicator. The glue enters the glue inlet channel through the glue inlet and then enters the flow channel through the glue inlet channel.

[0014] Furthermore, an arc-shaped connecting block is provided between the glue inlet and the glue flow section, and the flow channel passes through the arc-shaped connecting block and is connected to the glue inlet channel.

[0015] In the above scheme, the arc-shaped connecting block is used to improve the connection strength between the glue inlet and the glue flow section, and the flow channel passes through the inside of the arc-shaped connecting block to connect with the glue inlet channel in the glue inlet section.

[0016] Furthermore, the glue inlet is provided with a mounting base, and the mounting base has mounting holes.

[0017] In the above scheme, the adhesive applicator head is installed and fixed by means of the mounting base and the mounting holes provided thereon.

[0018] Secondly, this utility model provides a glue application device, which includes the aforementioned symmetrical dual-outlet glue application head and glue inlet assembly. The glue inlet assembly includes a spray valve and a glue inlet component connected to each other, and the glue inlet component is in communication with the flow channel.

[0019] In the above scheme, the glue inlet is connected to the spray valve. The glue inlet has a cavity for containing glue liquid, and the spray valve is used to guide the glue liquid in the glue inlet into the flow channel of the glue applicator.

[0020] Furthermore, it also includes an angle adjustment component and a height adjustment component. The angle adjustment component includes a rotary drive and a rotary seat connected to the rotary drive. The glue injection component is mounted on the rotary seat. The height adjustment component includes a lifting drive. The angle adjustment component is connected to the output end of the lifting drive. And / or, the glue injection component is connected to the flow channel in sequence through the glue inlet and the glue injection channel. And / or, the mounting base is connected to the spray valve through the mounting hole.

[0021] In the above solution, the glue inlet assembly and the glue applicator can be rotated by the rotary drive and the rotary seat to accommodate glue application requirements at different angles. The height of the glue applicator can be adjusted by the lifting drive to meet the glue application requirements of battery cells of different thicknesses. The glue is initially located in the glue inlet assembly and passes through the glue inlet, glue inlet channel and flow channel in sequence under the action of the spray valve. In addition, the glue applicator is mounted and fixed on the spray valve through the mounting holes on the mounting base.

[0022] Thirdly, this utility model provides a battery production equipment, which includes the aforementioned adhesive coating device.

[0023] As can be seen from the above, the beneficial effects of this utility model compared to the prior art are as follows: This application has two symmetrical glue outlets. The glue in the flow channel is divided into two glue outlets through two symmetrical glue outlet channels. The glue flow path is equal, which can ensure that the glue output of the two glue outlets is consistent. Compared with the existing technology of setting two glue outlets with different heights, it can effectively ensure the glue volume balance on both sides of the cell skirt, reduce glue overflow and leakage, and significantly improve the glue coating quality. The flow channel of this application is horizontally set. Compared with the vertical setting, it can eliminate the pressure difference caused by the upper and lower liquid columns during the flow of adhesive, so that the pressure distribution of adhesive in the flow channel is uniform and stable. This ensures that the pressure of the two adhesive outlets is equal and constant, ensuring that the amount of adhesive applied to each skirt section is consistent, and improving the uniformity and quality of adhesive application.

Detailed Implementation

[0031] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Example 1

[0032] Please refer to Figures 1 to 3 This utility model provides a symmetrical dual-outlet glue applicator 1, including a glue inlet section 11 and a glue flow section 12; the glue inlet section 11 is provided with a glue inlet port 111, and a glue inlet channel 112 connected to the glue inlet port 111 is provided inside the glue inlet section 111; the glue flow section 12 is provided with a horizontal flow channel 121 inside the glue flow section 12; the end of the glue flow section 12 is provided with a glue outlet groove 122, and two symmetrical glue outlets 123 are opened in the glue outlet groove 122, and the two glue outlets 123 are symmetrical about the horizontal plane; wherein, the glue inlet channel 112 is connected to the flow channel 121, and two symmetrical glue outlet channels 124 are provided between the flow channel 121 and the glue outlet groove 122, and the glue flowing out through the flow channel 121 is guided to the two glue outlets 123 through the two glue outlet channels 124 respectively.

[0033] Specifically, during the adhesive application process, the skirt of the battery cell is horizontally inserted into the adhesive outlet 122. The adhesive enters the adhesive inlet channel 112 through the adhesive inlet 111, and then passes through the adhesive inlet channel 112 and the flow channel 121 in sequence. Subsequently, the adhesive flowing out of the flow channel 121 is diverted to the two adhesive outlets 123 by the two adhesive outlet channels 124. The two adhesive outlets 123 are symmetrically arranged to apply adhesive to the upper and lower surfaces of the skirt.

[0034] The two glue outlet channels 124 and glue outlets 123 are symmetrically arranged with equal glue flow paths, which can ensure that the glue output of the two glue outlets 123 is consistent. Compared with the existing technology of setting two glue outlets 123 with different heights, it can effectively ensure the balance of glue volume on both sides of the battery cell skirt, reduce glue overflow and leakage, and significantly improve the glue coating quality.

[0035] Furthermore, it should be noted that in existing adhesive applicators, the internal flow channel is typically vertically positioned, with two outlets located vertically. Due to gravity, gravity creates a pressure difference in the adhesive flowing through this vertical channel. The adhesive near the lower outlet experiences pressure from the upper liquid column, resulting in a higher actual dispensing pressure than the upper outlet. This pressure imbalance between the two outlets can lead to uneven adhesive application on the skirt, affecting the overall coating quality. In contrast, this application horizontally positions the flow channel 121, eliminating the pressure difference caused by the liquid column. This ensures a uniform and stable pressure distribution of the adhesive within the flow channel 121, guaranteeing equal and constant dispensing pressure at both outlets 123. This ensures consistent adhesive application across each skirt section, improving the uniformity and quality of the coating.

[0036] Not limited to, in this embodiment, the included angle at the connection between the glue inlet 11 and the glue flow section 12 is 90°. In specific implementation, the included angle at the connection between the glue inlet 11 and the glue flow section 12 is preferably greater than 0° and less than 180°, as long as the glue flow section 12 and its internal flow channel 121 are set horizontally.

[0037] Please refer to Figure 3 The two glue outlets 123 are symmetrical about the horizontal plane, and the two glue outlet channels 124 are also symmetrical about the horizontal plane, so that the two glue flow paths are equal and the glue output and flow rate of the two glue outlets 123 are the same.

[0038] Please continue to refer to Figure 3 The glue dispensing section 12 is also provided with a transfer chamber 125. The transfer chamber 125 is located between the flow channel 121 and the glue outlet channel 124. The transfer chamber 125 is connected to the flow channel 121 and the glue outlet channel 124 and is used to transfer and buffer the glue liquid to better perform the glue liquid diversion work.

[0039] Please refer to Figures 1 to 3The inner wall of the glue dispensing groove 122 is a curved surface. The curved inner wall allows the glue to flow more smoothly and fill the glue dispensing groove 122 after flowing out of the glue outlet 123, thereby forming quickly. At the same time, the curved surface design can avoid dead corners, reducing the difficulty of subsequent cleaning work.

[0040] Preferably, such as Figure 3 As shown, a horizontally positioned slot 126 is provided on the left side of the glue outlet 122 to allow the skirt of the power supply core to be inserted.

[0041] Please refer to Figure 1 and Figure 2 An arc-shaped connecting block 13 is provided between the glue inlet section 11 and the glue flow section 12. The arc-shaped connecting block 13 is used to improve the connection strength between the glue inlet section 11 and the glue flow section 12. The flow channel 121 passes through the inside of the arc-shaped connecting block 13 to connect with the glue inlet channel 112 in the glue inlet section 11.

[0042] Please refer to Figure 1 and Figure 2 The top of the glue inlet 11 is provided with a mounting base 14, and the mounting base 14 has a mounting hole 141. The glue applicator 1 can be installed and fixed through the mounting base 14 and the mounting hole 141. Example 2

[0043] Please refer to Figure 4 and Figure 5 This utility model provides a glue application device 2, which includes a symmetrical dual-outlet glue application head 1 as described in Embodiment 1 and a glue inlet assembly 21. The glue inlet assembly 21 includes a spray valve 211 and a glue inlet component 212 connected to each other.

[0044] Specifically, the glue inlet 212 is connected to the spray valve 211. The glue inlet 212 has a cavity for containing glue liquid. The outlet of the spray valve 211 is connected to the glue inlet 111 of the glue applicator 1. The glue liquid in the glue inlet 212 is introduced into the glue inlet channel 112 through the glue inlet 111 by the spray valve 211. The glue liquid passes through the glue inlet channel 112, the flow channel 121, the transfer chamber 125, the glue outlet channel 124 and the glue outlet 123 in sequence, and then reaches the skirt surface of the battery cell.

[0045] In Example 1, the symmetrical dual-outlet applicator head 1 is connected and fixed to the spray valve 211 via the mounting base 14 and the mounting hole 141 provided thereon.

[0046] Preferably, the injection valve 211 is a piezoelectric ceramic valve.

[0047] Furthermore, the glue applicator 2 also includes an angle adjustment component 22 and a height adjustment component. The angle adjustment component 22 includes a rotary drive component 221 and a rotary seat 222 connected to the rotary drive component 221. The glue applicator 21 is mounted on the rotary seat 222. The height adjustment component includes a lifting drive component 23. The angle adjustment component 22 is connected to the output end of the lifting drive component 23.

[0048] The rotary drive 221 and the rotary seat 222 can drive the glue applicator 21 and the glue applicator 1 to rotate, so as to accommodate the glue applicator requirements at different angles. The height of the glue applicator 1 can be adjusted by the lifting drive 23 to meet the glue applicator requirements of battery cells of different thicknesses.

[0049] The rotating base 222 is equipped with a mounting plate 213, and the glue dispensing assembly 21 is mounted on the mounting plate 213. The rotating base 222 drives the glue dispensing assembly 21 to rotate by driving the mounting plate 213 to rotate.

[0050] Preferably, the lifting drive component 23 is a linear motor. Example 3
