[0031] The battery packing device and battery processing equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0032] like Figures 1-2 As shown, a battery packing device according to some embodiments of this application includes: a pressing assembly 100, a pushing assembly 200, and a limiting member 300; a pressing channel 110 is formed in the pressing assembly 100, and the pushing assembly 200 is disposed on one side of the pressing channel 110 along a first direction X, for pushing the battery 400 and the adhesive film 500 into the pressing channel 110 along the first direction X, so as to press the adhesive film 500 onto the surface of the battery 400 by the pressing assembly 100; the limiting member 300 is disposed on the other side of the pressing channel 110 along the first direction X, and the limiting member 300 can move perpendicular to the first direction X to approach or move away from the pressing channel 110, so as to limit the battery 400 in the pressing channel 110.

[0033] In this embodiment, a pressing component 100 and a pushing component 200 are provided. The pressing component 100 has a pressing channel 110. The pushing component 200 can push the battery 400 to be coated and the adhesive film 500 into the pressing channel 110 of the pressing component 100 so that the pressing component 100 can press the adhesive film 500 onto the surface of the battery 400. At the same time, a limiting member 300 is provided on the side of the pressing channel 110 away from the pushing component 200. After the pushing component 200 pushes the battery 400 into the pressing channel 110, the limiting member 300 can be moved to move closer to the pressing channel 110. The limiting member 300 is used to limit and fix the battery 400 in the pressing channel 110 so as to carry out the coating operation of the battery 400. This effectively reduces the phenomenon of shaking or displacement of the battery 400 during the coating process, thereby improving the coating quality.

[0034] Among them, such as Figure 1 and Figure 3 As shown, the first direction X refers to the direction of movement in which the pushing component 200 pushes the battery 400 into the pressing channel 110. The battery 400 includes a first side 410 and a second side 420 disposed opposite to each other along the first direction X, and a third side 430 and a fourth side 440 disposed opposite to each other perpendicular to the first direction X.

[0035] Specifically, if Figure 2 As shown, a pressing channel 110 is formed in the pressing assembly 100, and the pushing assembly 200 pushes the battery 400 and the adhesive film 500 together into the pressing channel 110. During the process of the battery 400 being pushed into the pressing channel 110, the pressing assembly 100 can press the adhesive film 500 to the third side 430 and the fourth side 440 of the battery 400; at the same time, the limiting member 300 moves along a direction perpendicular to the first direction X to approach the pressing channel 110, and moves the limiting member 300 to the side of the pressing channel 110 away from the pushing assembly 200. In this way, when the battery 400 is pushed into the pressing channel 110 by the pushing component 200, the pressing component 100 presses and fixes the battery 400 along the first direction X perpendicular to the first direction. At the same time, the limiting member 300 contacts the second side 420 of the battery 400, forming a limiting on the battery 400 along the first direction X, thereby limiting and fixing the battery 400 in the pressing channel 110, so that other sides of the battery 400 can be coated or other operations can be performed.

[0036] Optionally, such as Figure 1 As shown, the battery pack assembly also includes a mounting base 600. Figure 1 The image shows a partial structure of the mounting base 600. The clamping assembly 100 includes two clamping members 120 connected to the mounting base 600. The two clamping members 120 are spaced apart along a direction perpendicular to the first direction X to form a clamping channel 110 between the two clamping members 120.

[0037] In this embodiment, by setting the mounting base 600 to provide a stable working platform for the pressing assembly 100, the stability of the pressing assembly 100 during operation is improved. The pressing members 120 are connected to the mounting base 600 and are spaced apart along a direction perpendicular to the first direction X, forming a pressing channel 110 between the two pressing members 120. The pressing channel 110 can accommodate the battery 400 and the adhesive film 500. During the process of the battery 400 and the adhesive film 500 entering the pressing channel 110, the two opposing pressing members 120 can apply pressure to the battery 400 along the direction perpendicular to the first direction X, so that the adhesive film 500 can be better pressed onto the third side 430 and the fourth side 440 of the battery. Simultaneously, the cooperation of the two pressing members 120 can effectively fix the battery 400 along the direction perpendicular to the first direction X, effectively reducing the shaking of the battery 400 along the direction perpendicular to the first direction X during the pressing process, thereby improving the coating quality of the battery 400.

[0038] The preset height of the pressing channel 110 along the first direction X can be determined according to the length of the battery 400 along the first direction X, so that the battery 400 can pass through the pressing channel 110. At the same time, the pressing member 120 can also press and fix the battery 400.

[0039] Optionally, such as Figure 1 As shown, the clamping member 120 includes a plurality of rollers 121, which are arranged in a row at intervals along the first direction X, and the rollers 121 are rotatably connected to the mounting base 600.

[0040] In this embodiment, several rollers 121 can roll along the moving direction of the battery 400 to roll and press the adhesive film 500 on the surface of the battery 400. This not only allows the adhesive film 500 to better adhere to the surface of the battery 400, but also reduces the friction between the rollers 121 and the surface of the battery 400, thereby avoiding damage to the adhesive film 500 and the battery 400, affecting the coating quality, or even affecting the normal operation of the production equipment.

[0041] In another embodiment, the number of rollers 121 is at least two, and the at least two rollers 121 are spaced apart along the first direction X. The at least two rollers 121 form a roller row, and the upper and lower roller rows can form a rolling action on the upper and lower sides of the battery 400, thereby pressing the adhesive film 500 onto the third side 430 and the fourth side 440 of the battery 400.

[0042] In specific applications, a pressing channel 110 is formed between the two roller rows. When the battery 400 is pushed into the pressing channel 110 by the pushing component 200, at least two rollers 121 on the third side 430 or the fourth side 440 of the battery 400 press and fix the battery 400, so that the pressure on the battery 400 is in a balanced state, thereby better fixing the battery 400 along the direction perpendicular to the first direction X.

[0043] It is understood that the number of rollers 121 can be flexibly set according to the size of the battery 400, and this embodiment does not limit the number of rollers 121. An appropriate number of rollers can not only further improve the adhesion between the adhesive film 500 and the surface of the battery 400, but also enhance the pressing and fixing effect of the rollers 121 on the battery 400, further preventing the battery 400 from shaking during the rolling process.

[0044] Optionally, such as Figure 2 As shown, the battery packing device also includes a rolling assembly 700, which is located on the side of the pressing channel 110 near the pushing assembly 200. The rolling assembly 700 can move along a direction perpendicular to the first direction X to move closer to or away from the pressing channel 110, and is used to roll the battery 400 on both sides along the first direction X.

[0045] In this embodiment, the rolling assembly 700 can move along a direction perpendicular to the first direction X. When the pushing assembly 200 pushes the battery 400 and the film 500 along the first direction X to the corresponding position of the rolling assembly 700, the rolling assembly 700 can roll the first side 410 and the second side 420 of the battery 400 to realize the film coating operation on the corresponding side of the battery 400.

[0046] Specifically, such as Figure 2As shown, the roller pressing assembly 700 is located on the side of the pressing channel 110 near the pushing assembly 200, and the roller pressing assembly 700 is connected to the mounting base 600. The pushing assembly 200 pushes the battery 400 and the adhesive film 500 to move along the first direction X toward the pressing channel 110 and pass through the roller pressing assembly 700. When the second side 420 of the battery 400 reaches the corresponding position of the rolling assembly 700, the rolling assembly 700 moves toward the battery 400 along a direction perpendicular to the first direction X to press the adhesive film 500 onto the second side 420 of the battery 400. After rolling, the rolling assembly 700 moves away from the battery 400 along a direction perpendicular to the first direction X. Then, the pushing assembly 200 pushes the battery 400 into the pressing channel 110. During this process, the pressing assembly 100 presses the adhesive film 500 onto the third side 430 and the fourth side 440 of the battery 400. When the pushing assembly 200 pushes the first side 410 of the battery 400 into the corresponding position of the rolling assembly 700, the rolling assembly 700 moves toward the battery 400 again along a direction perpendicular to the first direction X to press the adhesive film 500 onto the first side 410. After rolling, the rolling assembly 700 moves away from the battery 400 along a direction perpendicular to the first direction X. This achieves the coating operation on the four sides of the battery 400.

[0047] In another embodiment, the mounting base 600 may also be provided with a second driving member (not shown in the figure). The second driving member is connected to the roller pressing assembly 700 and is used to drive the roller pressing assembly 700 to move closer to or away from the pressing channel 110 along a direction perpendicular to the first direction X. The second driving member can automatically adjust the position of the roller pressing assembly 700 relative to the pressing channel 110 according to a preset program, thereby improving production efficiency. Furthermore, when driving the roller pressing assembly 700 to work, the second driving member can control the pressure of the roller pressing assembly 700 on the surface of the battery 400, thereby improving the coating quality of the battery 400. It is understood that the second driving member can be a servo motor or a hydraulic drive assembly, and this embodiment does not limit it.

[0048] In addition, two roller pressing assemblies 700 can be provided, and the two roller pressing assemblies 700 are arranged at intervals along the first direction X perpendicular to the first direction. The two roller pressing assemblies 700 can move alternately along the first direction X perpendicular to the first direction to realize the coating operation on the first side 410 and the second side 420 of the battery 400. This can not only improve the efficiency of the coating process, but also improve the service life of the roller pressing assembly 700.

[0049] Optionally, such as Figure 2 As shown, the battery packing device also includes a first detection element 800, which is disposed on both sides of the pressing channel 110 perpendicular to the first direction X, and is used to detect the packing quality of the battery 400 on the side perpendicular to the first direction X.

[0050] In this embodiment, by providing first detection elements 800 on both sides of the pressing channel 110 perpendicular to the first direction X, the coating condition of the third side 430 and the fourth side 440 of the battery 400 can be detected. If defects such as bubbles or wrinkles appear in the adhesive film 500 that is bonded to the third side 430 and the fourth side 440, the detection elements 800 can identify the defects and remind the staff to pick out the defective products in time according to the preset program, thereby improving production efficiency and production quality.

[0051] Specifically, the first detection element 800 is disposed on both sides of the pressing channel 110 perpendicular to the first direction X, and is connected to the mounting base 600. The first detection element 800 can be a CCD camera. CCD cameras have high sensitivity and clear images, which can improve the quality and efficiency of coating detection.

[0052] Optionally, such as Figure 2 As shown, the battery packing device also includes a second detection element 900, which is located on the side of the pressing channel 110 away from the pushing component 200 along the first direction X, and is used to detect the packing quality of the side of the battery 400 along the first direction X.

[0053] In this embodiment of the application, by setting a second detection element 900, the coating quality of the first side 410 and the second side 420 of the battery 400 can be detected, thereby further improving the production efficiency and production quality of the battery 400.

[0054] Specifically, the second detection element 900 is disposed on the mounting base 600, and the second detection element 900 is disposed on the side of the pressing channel 110 away from the pushing component 200 along the first direction X. The second detection element 900 includes two detection elements, which are disposed back to back. When the battery 400 is gradually pushed into the pressing channel 110 by the pushing component 200, one of the detection elements can detect the coating quality of the second side 420; when the battery 400 is pushed out of the pressing channel 110, the other detection element 900 can detect the coating quality of the first side 410.

[0055] In another embodiment, the second detection element 900 can rotate at different angles to adjust the angle according to the position of the battery 400. When the battery 400 is gradually pushed into the pressing channel 110 by the pushing assembly 200, the second detection element 900 can detect the coating quality of the second side 420. When the battery 400 is pushed out of the pressing channel 110, the second detection element 900 can rotate to a suitable angle to detect the coating quality of the first side 410.

[0056] Optionally, such as Figure 2As shown, the second detection element 900 is connected to the limiting element 300. The second detection element 900 can move with the limiting element 300 along a direction perpendicular to the first direction X to approach or move away from the pressing channel 110.

[0057] In this embodiment of the application, by connecting the second detection element 900 to the limiting element 300, the second detection element can move simultaneously with the limiting element 300 along the direction perpendicular to the first direction X, thereby not only detecting the quality of the coating on the first side 410 of the battery 400, but also saving installation space.

[0058] Specifically, the second detection element 900 is connected to the limiting element 300. After the battery 400 is coated with adhesive film, the second detection element 900 and the limiting element 300 can move simultaneously along the first direction X perpendicular to move away from the pressing channel 110, making way for the battery 400 to be conveyed out of the pressing channel 110. After the battery 400 is conveyed out of the pressing channel 110 along the first direction X, the limiting element 300 and the second detection element 900 move again along the first direction X perpendicular to move closer to the pressing channel 110. At this time, the second detection element 900 can detect the coating quality of the first side 410. It is understood that the second detection element 900 can be a testing device such as a CCD camera, which will not be elaborated here.

[0059] Optionally, the limiting member 300 has a buffer layer on the side facing the pressing channel 110.

[0060] In some embodiments, the limiting member 300 is provided with a buffer layer on the side facing the pressing channel 110. When the battery 400 is pushed into the pressing channel 110 by the pushing component 200 and comes into contact with the limiting member 300, the buffer layer can absorb and disperse part of the impact force, reduce the rigid collision between the battery 400 and the limiting member 300, and protect the battery 400.

[0061] The buffer layer can be made of elastic materials such as rubber and polyurethane. Of course, other buffer materials can also be used, and this application does not limit them.

[0062] Optionally, the battery pack device further includes a first driving member (not shown in the figure), which is connected to the limiting member 300 and is used to drive the limiting member 300 to move along a direction perpendicular to the first direction X.

[0063] In this embodiment, the first driving component is disposed on the mounting base 600 and connected to the limiting component 300. The first driving component can automatically drive the limiting component 300 away from or towards the pressing channel 110 along a direction perpendicular to the first direction X. The first driving component can be a servo motor, which has the advantages of fast response speed and high position accuracy, and can improve the coating effect of the battery 400 and the production efficiency.

[0064] In another embodiment, the first driving component may also be a hydraulic cylinder, and this embodiment does not limit it.

[0065] Optionally, this application also proposes a battery processing device, including a film feeding device and the battery packing device in the above embodiments. The film feeding device is provided with an adhesive film 500 for conveying the adhesive film 500 into the pressing channel 110.

[0066] In this embodiment, a film feeding device (not shown in the figure) delivers adhesive film 500 into the pressing channel 110. By setting a pressing assembly 100 and a pushing assembly 200, the pressing assembly 100 is provided with a pressing channel 110. The pushing assembly 200 can push the battery 400 to be coated and the adhesive film 500 into the pressing channel 110 of the pressing assembly 100, so that the pressing assembly 100 can press the adhesive film 500 onto the surface of the battery 400. At the same time, a limiting member 300 is provided on the side of the pressing channel 110 away from the pushing assembly 200. After the pushing assembly 200 pushes the battery 400 into the pressing channel 110, the limiting member 300 can be moved to move closer to the pressing channel 110. The limiting member 300 is used to limit and fix the battery 400 in the pressing channel 110 so as to carry out the coating operation of the battery 400, thereby effectively reducing the phenomenon of shaking or displacement of the battery 400 during the coating process, thereby improving the coating quality.

[0067] It should be noted that the battery processing equipment in the embodiments of this application may include the battery packing device in any of the above embodiments. The specific structure and technical effects of the battery packing device can be found in the foregoing content, and will not be repeated here.
