Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0035] In one embodiment of this utility model, such as Figures 1-4As shown, an automatic battery casing polishing device is provided, including a substrate 1, an adsorption worktable 2, a frame 3, a moving mechanism 4, a movable plate 5, a guiding mechanism 6, and a polishing mechanism 7. The adsorption worktable 2 and the frame 3 are both connected to the substrate 1. The moving mechanism 4 is connected to the frame 3 and to the movable plate 5. The guiding mechanism 6 is connected to the movable plate 5 and the frame 3 respectively. The polishing mechanism 7 is connected to the movable plate 5.

[0036] The moving mechanism 4 includes a moving drive assembly 41 and a moving assembly 42. The moving drive assembly 41 is connected to the frame 3, and the moving assembly 42 is connected to both the moving drive assembly 41 and the movable plate 5. The moving drive assembly 41 drives the moving assembly 42 to move, which in turn moves the movable plate 5 and the grinding mechanism 7.

[0037] The polishing mechanism 7 includes a lifting assembly 71 and a polishing assembly 72. The lifting assembly 71 is connected to the movable plate 5, and the polishing assembly 72 is connected to the lifting assembly 71. The polishing assembly 72 includes a polishing frame 721, a rotating roller 722, an elastic fixing ring 723, and a polishing roller 724. The polishing frame 721 is connected to the lifting assembly 71, the rotating roller 722 is rotatably connected to the polishing frame 721, the elastic fixing ring 723 is fixedly sleeved on the rotating roller 722 and the polishing roller 724 respectively, the polishing roller 724 is rotatably connected to the polishing frame 721 and is located below the rotating roller 722, and the polishing roller 724 is located above the adsorption worktable 2.

[0038] The polishing process is as follows: Based on the thickness of the battery casing and the polishing requirements, the lifting assembly 71 begins to operate. The lifting cylinder 711 pushes the polishing frame 721 down, while the lifting guide rod 713 slides within the lifting guide cylinder 714 to ensure the smooth descent of the polishing frame 721.

[0039] As the polishing frame 721 descends, the rotating roller 722 and polishing roller 724 mounted on the polishing frame 721 also descend until the polishing roller 724 contacts the surface of the battery casing, reaching the appropriate polishing height.

[0040] Driven by the moving mechanism 4, the rotating roller 722 begins to rotate. Since the elastic retaining rings 723 are fixedly sleeved on both the rotating roller 722 and the polishing roller 724, the rotation of the rotating roller 722 is transmitted to the polishing roller 724 through the friction of the elastic retaining rings 723, causing the polishing roller 724 to also begin to rotate. The rotating polishing roller 724 polishes the surface of the battery casing, removing burrs, defects, etc., and improving the surface quality of the battery casing. Because three polishing rollers 724 are provided, they can polish different parts of the battery casing simultaneously, improving polishing efficiency and uniformity.

[0041] The automatic battery casing polishing equipment provided in this application, through the coordinated work of the moving mechanism 4 and the polishing mechanism 7, can achieve rapid and automatic polishing of the battery casing, improve production efficiency, and meet the needs of large-scale production. The setting of multiple polishing rollers 724 and the use of elastic fixing rings 723 make the polishing more uniform and can effectively improve the surface quality of the battery casing. The setting of the guide mechanism 6 ensures the stability of the movement of the movable plate 5, and the design of the lifting component 71 enables the polishing mechanism 7 to accurately control the polishing height, ensuring the stability and reliability of the equipment operation.

[0042] In another embodiment of the present invention, the mobile drive assembly 41 includes a mobile motor 411, a drive wheel 412 and a driven wheel 413. The mobile motor 411 is fixedly connected to the frame 3, the drive wheel 412 is fixedly connected to the mobile motor 411, and the driven wheel 413 is rotatably connected to the frame 3 and disposed on one side of the drive wheel 412.

[0043] The working principle of the moving drive assembly 41 is based on motor drive and belt transmission. The moving motor 411, as the power source, converts electrical energy into mechanical energy, driving the drive wheel 412 to rotate. The drive wheel 412 and the driven wheel 413 are connected by a moving belt 421. When the drive wheel 412 rotates, the friction between the belt and the wheel causes the moving belt 421 to move accordingly, thereby driving the driven wheel 413 to rotate. Since the belt clamp 422 is fixed on the moving belt 421 and is connected to the movable plate 5, the movement of the moving belt 421 will eventually drive the movable plate 5 to move, realizing the horizontal position adjustment of the grinding mechanism 7.

[0044] In another embodiment of the present invention, the moving component 42 includes a moving belt 421 and a belt clamp 422. The moving belt 421 is fixedly wound around the outside of the driving wheel 412 and the driven wheel 413 respectively. The belt clamp 422 is fixedly connected to the moving belt 421 and fixedly connected to the movable plate 5.

[0045] In another embodiment of the present invention, the lifting assembly 71 includes a lifting cylinder 711, a cylinder fixing plate 712, a lifting guide rod 713, and a lifting guide cylinder 714. The lifting cylinder 711 is fixedly connected to the cylinder fixing plate 712 and passes through the movable plate 5, and is fixedly connected to the grinding frame 721. One end of the lifting guide rod 713 is movably connected to the cylinder fixing plate 712, and the other end is fixedly connected to the grinding frame 721. The lifting guide cylinder 714 is movably sleeved on the outside of the lifting guide rod 713 and is fixedly connected to the movable plate 5.

[0046] The piston rod of the lifting cylinder 711 extends. Since the lifting cylinder 711 is fixed on the cylinder fixing plate 712, and the piston rod passes through the movable plate 5 and is fixedly connected to the grinding frame 721, the extension of the piston rod will push the grinding frame 721 to move downward. During the descent of the grinding frame 721, one end of the lifting guide rod 713 is movably connected to the cylinder fixing plate 712, and the other end descends with the grinding frame 721. At the same time, the lifting guide cylinder 714 is movably sleeved on the outside of the lifting guide rod 713 and fixedly connected to the movable plate 5. The lifting guide rod 713 slides smoothly within the lifting guide cylinder 714, providing precise guidance for the descent of the grinding frame 721, ensuring that the grinding frame 721 descends vertically and avoiding tilting or swaying.

[0047] In another embodiment of this utility model, there are three grinding rollers 724, all of which are rotatably connected to the grinding frame 721; the number of elastic fixing rings 723 is the same as that of the grinding rollers 724, and one elastic fixing ring 723 is fixedly sleeved on the outside of one grinding roller 724.

[0048] The polishing roller 724 obtains its rotational power through the friction between the elastic retaining ring 723 and the rotating roller 722. When the rotating roller 722 rotates, the elastic retaining ring 723, which is fitted on its outer side, moves accordingly. Since the elastic retaining ring 723 is also fitted on the outer side of the polishing roller 724, the rotation of the rotating roller 722 is transmitted to the polishing roller 724 through the elastic deformation and friction of the elastic retaining ring 723, causing the polishing roller 724 to rotate around its own axis, thereby polishing the surface of the battery casing. The three polishing rollers 724 work simultaneously, which can polish the battery casing from multiple angles, improving polishing efficiency and uniformity.

[0049] In another embodiment of this utility model, the elastic retaining ring 723 is a nitrile O-ring. Nitrile O-rings have good elasticity and a certain degree of hardness. When it is fitted onto the rotating roller 722 and the grinding roller 724 respectively, it generates a certain preload, establishing a tight connection between the rotating roller 722 and the grinding roller 724 through the O-ring. When the rotating roller 722 rotates, due to the friction between the O-ring and both the rotating roller 722 and the grinding roller 724, and because the O-ring has elastic deformation capability, it undergoes elastic deformation and rotates under the drive of the rotating roller 722, simultaneously transmitting the rotational motion to the grinding roller 724, causing the grinding roller 724 to also rotate around its own axis, thereby achieving power transmission. At the same time, the elasticity of the nitrile O-ring can, to a certain extent, buffer the vibration and impact generated during rotation. For example, when the grinding roller 724 encounters unevenness on the surface of the battery casing or other minor resistance, the O-ring can alleviate these impacts through its own elastic deformation, reducing damage to the overall structure of the equipment, while also helping to improve the stability and precision of the grinding.

[0050] In another embodiment of this utility model, the adsorption workbench 2 includes a manifold 21 and an adsorption plate 22. The manifold 21 is fixedly connected to the substrate 1, and the adsorption plate 22 is fixedly connected to the top side of the manifold 21. Multiple manifolds 21 are provided and evenly distributed, and the number of adsorption plates 22 is the same as that of the manifolds 21. When an external negative pressure source (such as a vacuum pump) is connected to and started by the manifold 21, a negative pressure environment is formed inside the manifold 21. Since multiple manifolds 21 are provided and evenly distributed, these manifolds 21 will evenly transmit the negative pressure to the adsorption plates 22 connected to them. The top side of the adsorption plate 22 is in contact with the battery casing. Under the action of negative pressure, the air between the adsorption plate 22 and the battery casing is extracted, forming a pressure difference, thereby generating an adsorption force that tightly adsorbs the battery casing onto the adsorption plate 22, keeping it in a fixed position during the polishing process, facilitating precise polishing by the polishing roller 724. Multiple evenly arranged busbars 21 and an equal number of adsorption plates 22 ensure that the adsorption force is evenly distributed on the bottom of the battery casing, preventing deformation or insecure fixation of the battery casing due to uneven local adsorption force. Especially for battery casings with irregular shapes or large sizes, this uniform adsorption method can better ensure their stability during the polishing process.

[0051] In another embodiment of this utility model, the guiding mechanism 6 includes a guide seat 61 and a guide rod 62. The guide seat 61 is movably inserted through the guide rod 62 and fixedly connected to the movable plate 5. The guide rod 62 is fixedly connected to the frame 3. Two guiding mechanisms 6 are provided and arranged in parallel and opposite directions. The guide seat 61 of one of the guiding mechanisms 6 is fixedly connected to the belt clamp seat 422. The guide seat 61 can move freely on the guide rod 62. When the movable plate 5 or the belt clamp seat 422 connected to it is subjected to an external force, the guide seat 61 will move along the direction of the guide rod 62. Since the guide rod 62 is fixed on the frame 3, it provides a fixed motion trajectory for the guide seat 61 and the components connected to it, so that the movable plate 5 and the belt clamp seat 422 and other components can perform smooth and accurate linear motion under the constraint of the two parallel and opposite guiding mechanisms 6, without any deviation or shaking. Ensuring that components such as the movable plate 5 and belt clamp 422 move in the direction determined by the guide rod 62, and that their movement trajectories are accurate, is crucial for the coordinated work between the various components of the equipment and helps to improve the stability and reliability of the entire equipment operation.

[0052] The automatic battery casing polishing equipment provided in this application, through the coordinated work of the moving mechanism 4 and the polishing mechanism 7, can achieve rapid and automatic polishing of the battery casing, improve production efficiency, and meet the needs of large-scale production. The setting of multiple polishing rollers 724 and the use of elastic fixing rings 723 make the polishing more uniform and can effectively improve the surface quality of the battery casing. The setting of the guide mechanism 6 ensures the stability of the movement of the movable plate 5, and the design of the lifting component 71 enables the polishing mechanism 7 to accurately control the polishing height, ensuring the stability and reliability of the equipment operation.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
