Description

Technical Field

[0001] This utility model relates to the field of aluminum shell coating technology for batteries, and more specifically, to a lithium-ion battery aluminum shell coating device. Background Technology

[0002] During the production of lithium-ion battery aluminum casings, the outer surface needs to be painted to achieve purposes such as insulation, corrosion resistance, or aesthetics. In existing technologies, an overhead chain conveyor is typically used to move the aluminum casings between painting stations. Steel wire hooks are installed at the bottom of the conveyor, and the battery aluminum casings are suspended one by one on the hooks, moving with the conveyor chain to the painting station where automatic spray guns perform the painting operation.

[0003] However, in this traditional suspension method, the steel wire hook and the aluminum shell are simply suspended. The hook cannot actively rotate the aluminum shell during the painting process, which means that the spray gun can only spray the side of the aluminum shell facing the spray gun, while the side facing away from the spray gun cannot be covered by paint. Usually, a double-sided painting process is used to process this. First, one side of the aluminum shell is sprayed, and after the paint film is cured, the aluminum shell is manually flipped over and suspended on the conveyor chain again for the other side to be sprayed. However, the two spraying and two curing processes result in a long production cycle and low processing efficiency. Utility Model Content

[0004] To address the technical problem of long production cycles and low processing efficiency caused by the two-stage spraying and curing processes in existing technologies, this utility model provides a lithium-ion battery aluminum shell coating device.

[0005] To achieve the above objectives, this utility model proposes a lithium-ion battery aluminum shell coating device, comprising an extension rod, a first hinge seat fixedly connected to the outer circumference of the extension rod, a rotating shaft rotatably connected to both ends of the first hinge seat, a connecting arm fixedly connected to the outer circumference of each of the two rotating shafts, a protruding rod fixedly connected to the outer wall of each connecting arm, a clamping plate fixedly connected to the lower end of each connecting arm, two rubber blocks fixedly connected to the relatively far sides of each of the two clamping plates, a connecting rod fixedly connected to the bottom end of the extension rod, a second spring sleeved on the outer wall of the connecting rod, a second hinge seat slidably connected to the outer circumference of the connecting rod, a rotating arm rotatably connected to both ends of the second hinge seat, a hinge block rotatably connected to the end of each rotating arm, the end of each hinge block being fixedly connected to the connecting arm, one end of the second spring being fixedly connected to the second hinge seat, and the other end of the second spring being fixedly connected to the bottom end of the extension rod.

[0006] Through the above technical solution, under the elastic force of the second spring, the clamping plate drives the rubber block to achieve the clamping of the two clamping plates on the inner wall of the aluminum shell, avoiding damage to the surface of the aluminum shell during the clamping process, while enhancing the clamping stability and ensuring that the aluminum shell does not deviate when rotating.

[0007] Furthermore, it also includes a slide rail, a mounting sleeve, and a spray gun. The outer wall of the mounting sleeve is fixedly connected to two support shafts, one of which extends into the slide rail. A roller is rotatably connected to the end of the support shaft, and the roller is in rolling connection with the inner wall of the slide rail. The spray gun is located below one side of the slide rail and is used to spray paint onto the aluminum casing of the battery.

[0008] Through the above technical solution, the cooperation between the slide rail and the roller guides the movement of the device, ensuring that the aluminum shell moves along the preset path, so that the spray gun can spray the aluminum shell.

[0009] Furthermore, a connecting sleeve is rotatably connected to the inner wall of the mounting sleeve, a rotating wheel is fixedly connected to the outer circumference of the connecting sleeve, and a rubber plate is fixedly connected to the outer wall of the slide rail, with the rotating wheel in frictional contact with the rubber plate.

[0010] Through the above technical solution, the frictional contact between the rotating wheel and the rubber plate converts the linear movement of the device into the rotational force of the connecting sleeve, thereby driving the aluminum casing of the battery to rotate.

[0011] Furthermore, a connecting plate is fixedly connected to the outer circumference of another support shaft, and a slider is fixedly connected to the end of the connecting plate. A convex edge is formed on the side wall of the slide rail, and the slider is slidably connected to the convex edge.

[0012] Through the above technical solution, the sliding cooperation between the slider and the convex edge further restricts the movement direction of the device, prevents the device from tipping over or deviating during movement, and improves the operational stability of the device.

[0013] Furthermore, a connecting shaft is fixedly connected to the outer wall of the connecting plate. The connecting shaft is used to connect to the chain of the overhead chain conveyor so that the connecting plate moves with the chain.

[0014] Through the above technical solution, the connecting shaft connects the device to the overhead chain conveyor, enabling the device to move synchronously with the chain.

[0015] Furthermore, the top of the extension rod extends into the connecting sleeve and is slidably connected thereto. The outer wall of the extension rod has multiple locking holes. The outer wall of the connecting sleeve is slidably connected to a locking rod. The end of the locking rod passes through the locking holes and is slidably connected thereto. The outer wall of the locking rod is fitted with a first spring. One end of the first spring is fixedly connected to the locking rod, and the other end of the first spring is fixedly connected to the connecting sleeve.

[0016] Through the above technical solution, the cooperation between the clamping rod and the clamping holes of different heights enables flexible adjustment of the extension rod height, adapts to the painting needs of aluminum shells of different specifications, and improves the versatility of the device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By using the frictional contact between the rotating wheel and the rubber plate, the linear movement of the device is converted into the rotational force of the connecting sleeve, which in turn drives the aluminum shell of the battery to rotate. During the painting process, the aluminum shell rotates continuously, allowing the spray gun to cover its entire surface. This enables the entire surface to be painted in one spray, eliminating the need for secondary spraying and curing, thus shortening the production cycle and improving processing efficiency.

[0019] 2. Under the elastic force of the second spring, the clamping plate drives the rubber block to clamp the inner wall of the aluminum shell with the two clamping plates, so as to avoid damage to the surface of the aluminum shell during the clamping process, and at the same time enhance the clamping stability and ensure that the aluminum shell does not deviate when rotating.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 3 and Figure 4As shown, a lithium-ion battery aluminum shell coating device includes an extension rod 13. A first hinge seat 18 is fixedly connected to the outer circumference of the extension rod 13. A rotating shaft 17 is rotatably connected to both ends of the first hinge seat 18. A connecting arm 19 is fixedly connected to the outer circumference of both rotating shafts 17. A protruding rod 20 is fixedly connected to the outer wall of each connecting arm 19. A clamping plate 26 is fixedly connected to the lower end of the connecting arm 19. Two rubber blocks 27 are fixedly connected to the relatively far sides of the two clamping plates 26. A connecting rod 21 is fixedly connected to the bottom end of the extension rod 13. A second spring 22 is sleeved on the outer wall of the connecting rod 21. A second hinge seat 23 is slidably connected to the outer circumference of the connecting rod 21. A rotating arm 24 is rotatably connected to both ends of the second hinge seat 23. A hinge block 25 is rotatably connected to the end of each rotating arm 24. The ends of the hinge blocks 25 are fixedly connected to the connecting arm 19 respectively. One end of the second spring 22 is fixedly connected to the second hinge seat 23, and the other end of the second spring 22 is fixedly connected to the bottom end of the extension rod 13.

[0028] Under the elastic force of the second spring 22, the clamping plate 26 drives the rubber block 27 to achieve clamping of the inner wall of the aluminum shell by the two clamping plates 26, avoiding damage to the surface of the aluminum shell during the clamping process, while enhancing the clamping stability and ensuring that the aluminum shell does not deviate when rotating.

[0029] like Figure 1 and Figure 2 As shown, the lithium-ion battery aluminum shell painting device also includes a slide rail 1, a mounting sleeve 5 and a spray gun 12. Two support shafts 3 are fixedly connected to the outer wall of the mounting sleeve 5. One end of the support shaft 3 extends into the slide rail 1. A roller 4 is rotatably connected to the end of the support shaft 3. The roller 4 is rolled in connection with the inner wall of the slide rail 1. The spray gun 12 is located below one side of the slide rail 1 and is used to spray paint onto the battery aluminum shell.

[0030] The cooperation between the slide rail 1 and the roller 4 guides the movement of the device, ensuring that the aluminum shell moves along the preset path so that the spray gun 12 can spray the aluminum shell.

[0031] like Figure 2 As shown, a connecting sleeve 6 is rotatably connected to the inner wall of the mounting sleeve 5, a rotating wheel 7 is fixedly connected to the outer circumference of the connecting sleeve 6, and a rubber plate 11 is fixedly connected to the outer wall of the slide rail 1. The rotating wheel 7 and the rubber plate 11 are in frictional contact.

[0032] The frictional contact between the rotating wheel 7 and the rubber plate 11 converts the linear movement of the device into the rotational force of the connecting sleeve 6, which in turn drives the aluminum casing of the battery to rotate.

[0033] like Figure 2 As shown, a connecting plate 9 is fixedly connected to the outer circumference of another support shaft 3, and a slider 10 is fixedly connected to the end of the connecting plate 9. A protruding edge 2 is formed on the side wall of the slide rail 1, and the slider 10 is slidably connected to the protruding edge 2.

[0034] The sliding engagement between the slider 10 and the protruding edge 2 further restricts the direction of movement of the device, preventing the device from tipping over or shifting during movement and improving the stability of the device operation.

[0035] like Figure 2 As shown, a connecting shaft 8 is fixedly connected to the outer wall of the connecting plate 9. The connecting shaft 8 is used to connect the chain of the overhead chain conveyor so that the connecting plate 9 moves with the chain.

[0036] The connecting shaft 8 connects the device to the overhead chain conveyor, enabling the device to move synchronously with the chain.

[0037] like Figure 5 As shown, the top of the extension rod 13 extends into the connecting sleeve 6 and is slidably connected thereto. The outer wall of the extension rod 13 has multiple locking holes 14. The outer wall of the connecting sleeve 6 is slidably connected to a locking rod 15. The end of the locking rod 15 passes through the locking hole 14 and is slidably connected thereto. The outer wall of the locking rod 15 is fitted with a first spring 16. One end of the first spring 16 is fixedly connected to the locking rod 15, and the other end of the first spring 16 is fixedly connected to the connecting sleeve 6.

[0038] The combination of the lever 15 and the locking holes 14 of different heights enables flexible adjustment of the height of the extension rod 13, adapting to the painting needs of aluminum shells of different specifications and improving the versatility of the device.

[0039] The implementation principle of this application is as follows: When installing the battery aluminum shell, press down on the lower part of the two connecting arms 19. The connecting arms 19 push the second hinge seat 23 to slide along the connecting rod 21 through the rotating arm 24, compressing the second spring 22 and putting the battery aluminum shell on the two clamping plates 26. Release the connecting arms 19. Under the elastic force of the second spring 22, the rotating arm 24 pushes the connecting arms 19 through the hinge block 25, so that the clamping plates 26 squeeze the inner wall of the aluminum shell and fix the aluminum shell.

[0040] The connecting shaft 8 is moved by the chain on the overhead conveyor, which in turn moves the support shaft 3 and the connecting plate 9. The support shaft 3 drives the roller 4 to roll in the slide rail 1, while the connecting plate 9 drives the slider 10 to slide along the convex edge 2.

[0041] The rotating wheel 7 moves with the mounting sleeve 5. When the rotating wheel 7 comes into contact with the rubber plate 11, it rotates. The rotating wheel 7 drives the connecting sleeve 6 to rotate. The connecting sleeve 6 drives the extension rod 13 to rotate through the locking rod 15, so that the extension rod 13 rotates together with the connecting sleeve 6, thereby driving the battery aluminum shell to rotate.

[0042] When the extension rod 13 rotates, the first hinge seat 18 rotates with the extension rod 13. The connecting arm 19 is rotatably connected to the first hinge seat 18 via the pivot 17, so the connecting arm 19 and the clamping plate 26 fixed to its lower end rotate accordingly. The battery aluminum shell clamped between the clamping plates 26 rotates accordingly.

[0043] The spray gun 12 is positioned below one side of the slide rail 1 and sprays paint onto the rotating aluminum battery casing. The continuous rotation of the aluminum casing causes the paint to cover its surface.

[0044] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
