Technical Field
[0001] This invention relates to the field of solid-state battery cell processing technology, specifically to an auxiliary leveling clamping mechanism for solid-state battery cell processing. Background Technology
[0002] Solid-state batteries, as the core component of the next generation of power batteries, have significant advantages such as high energy density, good safety, long cycle life, and no risk of electrolyte leakage. They have been widely used in new energy vehicles, energy storage equipment and other fields. In the process of large-scale production of solid-state batteries, the clamping mechanism is a key piece of equipment that runs through the entire process of wafer fabrication, stacking, hot pressing, testing and assembly. Its clamping stability, positioning accuracy and protection effect on the battery cells directly determine the product quality and production efficiency of solid-state batteries.
[0003] For example, in the case of a battery cell clamping mechanism and a battery cell processing device as disclosed in announcement number CN223117521U, the battery cell clamping mechanism includes a frame, a clamping assembly, and a support member. The clamping assembly is mounted on the frame and includes two upper clamping arms and two lower clamping arms. One upper clamping arm is correspondingly disposed above one of the lower clamping arms. The two upper clamping arms and the two lower clamping arms can move relative to each other to clamp or release both ends of the battery cell. The support member is connected to the clamping assembly and is located between the two lower clamping arms to support the middle part of the battery cell.
[0004] The existing technologies mentioned above have the following technical problems: When clamping the battery cells, the existing battery cell clamping mechanisms can only play a simple clamping role. For solid-state batteries, problems such as edge warping, local bulges, and surface wavy deformation are prone to occur during the preparation and post-processing processes such as wafer fabrication, stacking, hot pressing, and transfer. Traditional production lines need to add a separate leveling station when processing uneven battery cell surfaces. This can easily lead to an increase in the number of stations on the production line, and a longer battery cell clamping time, thereby reducing the overall production efficiency.
[0005] Therefore, we propose an auxiliary leveling clamping mechanism for solid-state battery cell processing to solve the problems mentioned above. Summary of the Invention
[0006] The purpose of this invention is to provide an auxiliary leveling clamping mechanism for solid-state battery cell processing, in order to solve the problem mentioned in the background art. The existing battery cell clamping mechanisms on the market can only perform a simple clamping function when clamping the battery cells. For solid-state batteries, problems such as edge warping, local bulges, and surface wavy deformation are prone to occur during the preparation and post-processing processes such as wafer fabrication, stacking, hot pressing, and transfer. Traditional production lines need to add a separate leveling station when processing uneven battery cell surfaces. This can easily lead to an increase in the number of stations on the production line, and a longer clamping time for the battery cells, thereby reducing the overall production efficiency.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary leveling clamping mechanism for solid-state battery cell processing, comprising a support base and a rodless cylinder mounted on the support base, wherein a vertical guide frame is mounted on the telescopic end of the rodless cylinder, a linear guide rail is mounted on the vertical guide frame, and a movable plate is mounted on the linear guide rail, a rotary cylinder is fixed on the movable plate, and a locking seat is connected to the output end of the rotary cylinder, a sliding cylinder is mounted on the locking seat, and an adjusting plate is mounted on the telescopic end of the sliding cylinder, two adjusting plates are mounted on the sliding cylinder, and clamping components are mounted on both adjusting plates. The opening and closing of the clamping components on the two adjusting plates are used to clamp and limit the battery cell and to roll and level the surface of the battery cell.
[0008] Preferably, the movable plate can slide on the linear guide rail on the side of the vertical guide frame, and the bottom slider of the vertical guide frame is mounted on the guide rail on the support base.
[0009] By adopting the above technical solution, the sliding of the vertical guide frame on the support base makes it easy to adjust the front and back of the moving plate.
[0010] Preferably, the adjusting plates are symmetrically arranged about the transverse central axis of the slide cylinder, and the clamping components on the upper and lower adjusting plates are located on the same vertical straight line.
[0011] By adopting the above technical solution, the relative movement of two adjusting plates can be controlled by the slide cylinder, and the relative movement of the adjusting plates can facilitate the opening and closing of the clamping component.
[0012] Preferably, the clamping component includes a dual-axis motor mounted on an adjusting plate, and the output end of the dual-axis motor is connected to a connecting screw. A movable block is mounted on the connecting screw, and a clamping component is inserted into the movable block. A first electromagnet is embedded in the end of the clamping component near the movable block, and a insertion slot is opened at the end of the clamping component inserted into the movable block. An insertion block fixed inside the movable block is inserted into the insertion slot. A second electromagnet is embedded in both the end of the clamping component inserted into the movable block and the interior of the movable block. A transmission half gear is fixed on the clamping component, and a power rack is fixed on one of the adjusting plates on the side of the slide cylinder.
[0013] By adopting the above technical solution, the movement of the movable block enables the transmission half gear on the clamping member to mesh with the power rack, allowing the clamping member to rotate during the movement.
[0014] Preferably, the connecting screws on both output ends of the dual-axis motor have opposite thread directions, and the connecting screws and the movable block are threadedly connected, allowing the movable block to move on the adjustment plate.
[0015] By adopting the above technical solution, and by having the threads on the connecting screw surfaces run in opposite directions, the two movable blocks on the connecting screw can move synchronously relative to each other.
[0016] Preferably, the clamping member is rotatable on the movable block, and the longitudinal section of the clamping member is set as a semi-circular structure, the longitudinal section of the insertion groove on the clamping member is set as a "T" shaped structure, and multiple insertion blocks are inserted into the insertion groove on the clamping member, with the outer wall of the insertion block and the inner wall of the insertion groove fitting together.
[0017] By adopting the above technical solution, the clamping component can be prevented from falling off the movable block by inserting the plug block into the plug slot of the "T" shaped structure.
[0018] Preferably, the second electromagnet at the end of the clamping member and the second electromagnet inside the movable block can attract each other after being energized, and the first electromagnets on the upper and lower clamping members on the side of the adjustment plate can attract each other after being energized.
[0019] By adopting the above technical solution, when the upper and lower clamping parts are closed, the first electromagnet can be used to make them attract each other, thereby ensuring the stability of the two clamping parts after they are closed.
[0020] Preferably, after the clamping members on the upper and lower adjustment plates are closed, the transmission half gears on the clamping members are also closed synchronously, and the closed transmission half gears and the power rack form a meshing transmission structure.
[0021] By adopting the above technical solution, when the two transmission half gears are engaged, they can form a complete circular gear. When the movable block moves, the clamping part can be rotated by the action of the power rack and the engaged transmission half gear.
[0022] Preferably, a buffer plate is installed on the side of the clamping member facing the battery cell, and the buffer plate is connected to the clamping member through a built-in spring, forming an elastic telescopic structure through the built-in spring and the clamping member.
[0023] By adopting the above technical solution, the buffer plate and the built-in spring can play a clamping and buffering role when the battery cell is clamped by the plane of the clamping component.
[0024] Compared with the prior art, the beneficial effects of the present invention are: the auxiliary leveling clamping mechanism for solid-state battery cell processing has the following advantages: by setting clamping members symmetrically distributed vertically, and the longitudinal section of the clamping members is set as a semi-circle, the plane of the semi-circular structure can stably clamp the battery cell. At the same time, the clamping members can form a cylindrical structure when closed. The movement of the clamping members can roll the surface of the battery cell, thereby achieving auxiliary leveling of the battery cell surface.
[0025] 1. The relative movement of two adjusting plates can be controlled by the slide cylinder. The relative movement of the adjusting plates can be used to stabilize and limit the solid-state battery cell through the clamping component. The clamping component has a semi-circular cross-section. The plane of the clamping component can increase the contact area with the surface of the solid-state battery cell compared with a circular cross-section, thereby increasing the stability when clamping the solid-state battery cell.
[0026] 2. By adjusting the relative movement of the plates, the two clamping parts can be combined to form a cylindrical structure. The connecting screw can control the movement of the movable block. The movement of the movable block allows the clamping parts to move and roll along the surface of the solid-state battery cell. At the same time, the clamping parts can rotate under the action of the transmission half gear and the power rack when they move, thereby achieving the rolling and leveling of the solid-state battery cell.
[0027] 3. By installing a buffer plate on the clamping component, when the clamping component clamps the solid-state battery cell, the elastic deformation of the spring built into the buffer plate can play a clamping and buffering role on the solid-state battery cell, thereby avoiding damage to the solid-state battery cell due to excessive clamping force.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] Example 1: Please refer to Figures 1-9Existing battery cell clamping mechanisms can only provide simple clamping for battery cells. For solid-state batteries, issues such as edge warping, localized protrusions, and surface wavy deformation are prone to occur during the fabrication, stacking, hot pressing, and transfer processes. Traditional production lines require additional leveling stations for uneven battery cell surfaces, increasing the number of stations and clamping time, thus reducing overall production efficiency. To address this problem, this embodiment discloses an auxiliary leveling clamping mechanism for solid-state battery cell processing, comprising a support base 1 and a rodless cylinder 2 mounted on the support base 1. The telescopic end of the battery cell is equipped with a vertical guide frame 3, a linear guide rail 4, and a movable plate 5. A rotary cylinder 6 is fixed on the movable plate 5, and the output end of the rotary cylinder 6 is connected to a locking seat 7. A slide cylinder 8 is mounted on the locking seat 7, and an adjusting plate 9 is mounted on the telescopic end of the slide cylinder 8. Two adjusting plates 9 are mounted on the slide cylinder 8, and each adjusting plate 9 is equipped with a clamping component 10. The clamping components 10 on the two adjusting plates 9 open and close to clamp and limit the battery cell and to roll and flatten the surface of the battery cell. The movable plate 5 can slide on the linear guide rail 4 on the side of the vertical guide frame 3, and the bottom slider of the vertical guide frame 3 is mounted on the guide rail on the support base 1. The adjusting plate 9 is related to the slide cylinder 8. The clamping components 10 on the upper and lower adjusting plates 9 are symmetrically arranged along the horizontal central axis and are located on the same vertical straight line. The clamping component 10 includes a dual-axis motor 101 mounted on the adjusting plate 9, and the output end of the dual-axis motor 101 is connected to a connecting screw 102. A movable block 103 is mounted on the connecting screw 102, and a clamping member 104 is inserted into the movable block 103. A first electromagnet 105 is embedded in one end of the clamping member 104 near the movable block 103, and an insertion groove 106 is opened at one end of the clamping member 104 inserted into the movable block 103. An insertion block 107 fixed inside the movable block 103 is inserted into the insertion groove 106. Both the end of the clamping member 104 inserted into the movable block 103 and the interior of the movable block 103 are fitted with... The device includes a second electromagnet 108, a transmission half-gear 109 fixed on the clamping member 104, a power rack 110 fixed on one of the adjusting plates 9 on the side of the slide cylinder 8, and connecting screws 102 on both output ends of the dual-axis motor 101 with opposite thread directions. The connecting screws 102 and the movable block 103 are threadedly connected, allowing the movable block 103 to move on the adjusting plate 9 and the clamping member 104 to rotate on the movable block 103. The longitudinal section of the clamping member 104 is semi-circular, and the longitudinal section of the insertion slot 106 on the clamping member 104 is T-shaped. Multiple insertion blocks 107 are inserted into the insertion slot 106 on the clamping member 104, with the outer wall of the insertion block 107 and the inner wall of the insertion slot 106 fitting together.The second electromagnet 108 at the end of the clamping member 104 and the second electromagnet 108 inside the movable block 103 can attract each other after being energized. Similarly, the first electromagnets 105 on the upper and lower clamping members 104 on the side of the adjusting plate 9 can attract each other after being energized. After the clamping members 104 on the upper and lower adjusting plates 9 are closed, the transmission half gear 109 on the clamping member 104 also closes synchronously. The closed transmission half gear 109 and the power rack 110 form a meshing transmission structure.
[0040] When it is necessary to clamp the solid-state battery cell, the height of the moving plate 5 can be controlled by the linear guide rail 4, thereby adjusting the height position of the clamping component 10. At the same time, the vertical guide frame 3 can be moved and adjusted on the support base 1 by the rodless cylinder 2, so that the clamping components 104 on the upper and lower adjustment plates 9 can be distributed on the upper and lower sides of the solid-state battery cell. Then, the sliding cylinder 8 can be used to control the two adjustment plates 9 to move towards the solid-state battery cell, thereby using the two clamping components 104 to clamp and limit the solid-state battery cell. After clamping the battery cell, the rotating cylinder 6 can be used to control the locking seat 7 to rotate, thereby flipping the solid-state battery cell after it has been limited.
[0041] When auxiliary leveling of the solid-state battery cell surface is required, the two adjusting plates 9 are moved relative to each other by the slide cylinder 8, causing the clamping parts 104 on the two adjusting plates 9 to close together. After the clamping parts 104 close together, the first electromagnet 105 is energized, and the upper and lower clamping parts 104 attract each other to form a cylindrical structure. After the clamping parts 104 close together, the transmission half gear 109 on them also closes synchronously, thus forming a complete circular gear. Then, the second electromagnet 108 is de-energized, thereby releasing the fixation between the clamping parts 104 and the movable block 103. The height of the moving plate 5 can be controlled by the linear guide rail 4, so that the closed clamping parts 104 are pressed tightly against the surface of the solid-state battery cell. After that, the process begins. The dual-axis motor 101 is started, which enables the connecting screw 102 to rotate. The rotation of the connecting screw 102 causes the threaded movable block 103 to move outward toward the adjusting plate 9. After the movable block 103 moves, it can drive the clamping member 104 to move synchronously. After the clamping member 104 moves, it can also rotate on its own as it moves with the movable block 103 by utilizing the meshing action of the closed transmission half gear 109 and the power rack 110. This achieves auxiliary leveling of the solid-state battery cell surface, thereby integrating the clamping and auxiliary leveling functions into one, shortening the production line processing time and simplifying the production line processing station.
[0042] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. To facilitate clamping of solid-state battery cells and reduce damage to the cell surface, the following technical content is disclosed in this example: Figure 3, Figure 5 and Figure 7 As shown, a buffer plate 111 is installed on the side of the clamping member 104 facing the battery cell, and the buffer plate 111 is connected to the clamping member 104 through the built-in spring 112. The buffer plate 111 and the clamping member 104 form an elastic telescopic structure through the built-in spring 112 and the clamping member 104.
[0043] When the clamping member 104 clamps the battery cell, the buffer plate 111 on the clamping member 104 first contacts the solid battery cell. After the buffer plate 111 is subjected to force, the built-in spring 112 can undergo elastic deformation, thereby playing a clamping and buffering role. The longitudinal section of the clamping member 104 is set as a semi-circular structure. The plane of the semi-circular structure can increase the contact area with the battery cell. Compared with the clamping part with a circular longitudinal section, the contact area is larger and the clamping is more stable.
[0044] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
