Description

Technical Field

[0001] This utility model belongs to the field of solid-state battery production technology, and specifically relates to a positioning tooling for solid-state batteries. Background Technology

[0002] Solid-state batteries replace the liquid electrolyte in traditional lithium-ion batteries with a solid electrolyte, giving them advantages in safety and energy density. Solid electrolytes are non-flammable, fundamentally eliminating the risks of thermal runaway, combustion, and explosion associated with traditional liquid batteries. They can pass stringent tests such as needle penetration, shearing, and high-temperature testing. The positioning fixtures used in the solid-state battery manufacturing process are indeed crucial, directly affecting production precision, efficiency, and battery product quality. Due to the inherent structural and material characteristics of solid-state batteries (such as the brittleness of the solid electrolyte and the stringent requirements for interface contact), the positioning, clamping, and transport processes during solid-state battery manufacturing are far more complex than those for traditional lithium batteries.

[0003] Existing positioning fixtures for solid-state batteries typically employ motor drive, such as a combination of bidirectional studs and a motor, to place the solid-state battery workpiece in a designated position for symmetrical clamping. The design and material selection of the fixtures prioritize the protection of the battery body, preventing damage to the brittle solid electrolyte layer or electrode materials from hard contact or excessive clamping force. These fixtures address the unique challenges of solid-state battery materials and manufacturing processes through precise clamping, angle adjustment, and automated transfer. However, in practical applications, the need to produce large quantities of solid-state batteries at once necessitates the use of fast and efficient clamping solutions. This results in a relatively uniform clamping effect, potentially leading to vibrations during subsequent grinding, drilling, and other processes, which could affect the accuracy of subsequent machining. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a positioning fixture for solid-state batteries. This fixture allows the solid-state battery workpiece to be quickly and stably clamped in both horizontal and vertical directions, thereby stabilizing its placement and facilitating subsequent processing operations such as grinding and drilling.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a positioning fixture for solid-state batteries, including a worktable, a support fixedly mounted on the upper surface of the worktable, a rotating seat rotatably mounted on the upper side of the support, two symmetrically distributed clamping frames slidably mounted on the rotating seat, a clamping seat fixedly mounted on the upper end of the side of the clamping frame away from the rotating seat, two vertically symmetrically distributed rotating rods rotatably mounted on each clamping seat, and clamping rods fixedly sleeved at both ends of the rotating rods; a rubber pad is glued and fixedly mounted on the side of the clamping seat near the vertical center of the support, and a rubber block is sleeved at the end of the clamping rod near the horizontal center of the clamping seat; multiple door panels are rotatably mounted on the front side of the worktable, and handles are fixedly mounted on the front side of each door panel; multiple support legs are mounted on the lower surface of the worktable.

[0006] As a further improvement of this utility model, a worm gear is fixedly sleeved in the middle of the outer arc surface of the rotating rod, and a worm is rotatably arranged in the middle of the clamping seat. The worm gear is meshed with the adjacent worm. A servo motor is arranged on the outer side of the clamping seat. The output shaft of the servo motor is fixed to the adjacent worm through a coupling.

[0007] As a further improvement of this utility model, a driven plate is fixedly installed on the side of the clamping frame near the vertical center of the rotating seat. Two symmetrically distributed guide rails are fixedly installed inside the rotating seat, and the guide rails are slidably connected to the driven plate. Two symmetrically distributed support plates are fixedly installed in the middle of the rotating seat. An adjusting screw is rotatably installed in the middle of each support plate, and the adjusting screw is threadedly connected to the adjacent driven plate. A dual-axis motor is fixedly installed between the support plates, and the output shaft of the dual-axis motor is fixed to the adjacent adjusting screw through a coupling.

[0008] As a further improvement of this utility model, a worm gear two is fixedly sleeved at the lower end of the rotating seat, a worm two is rotatably arranged inside the support, the worm two is meshed with the worm gear two, and a servo motor two is arranged on the outer side of the support. The output shaft of the servo motor two is fixed to the adjacent worm two through a coupling.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the output shafts of the dual-axis motors drive the adjusting screws connected to them to rotate. Then, through the threaded relationship between the adjusting screws and the driven plates, the driven plates on both sides slide between two symmetrically distributed guide rails. This allows the clamping seats on both sides to clamp and fix the solid-state battery workpiece placed on the upper surface of the rotating seat in a horizontal direction. During the clamping and fixing process, the rubber pads on the clamping seats allow the rotating seat to make flexible contact with the solid-state battery workpiece while stably clamping it.

[0010] Secondly, the operation of the two servo motors is controlled, which in turn causes the output shafts of the servo motors to drive the worm gears connected to them to rotate. This causes the rotating rods to drive the clamping rods at their ends to rotate around the rotating rods as the center. This causes the clamping rods on the upper and lower sides to rotate synchronously in opposite directions, so that the ends of the clamping rods are close to the upper and lower sides of the solid-state battery workpiece and clamp and fix it in the vertical direction. During the clamping and fixing process, the rubber blocks at the ends of the clamping rods allow the clamping rods to make flexible contact with the solid-state battery workpiece while stably clamping it.

[0011] Third, the operation of the second servo motor is controlled, which in turn causes the output shaft of the second servo motor to drive the worm gear connected to it to rotate, which in turn causes the rotating seat to drive the clamped solid-state battery workpiece to rotate, thereby stabilizing the placement state of the solid-state battery workpiece and facilitating subsequent processing operations.

[0012] Fourth, through the cooperation of servo motor one, servo motor two and dual-axis motor, the solid-state battery workpiece can be quickly and stably clamped in the horizontal and vertical directions, and the placement state of the solid-state battery workpiece can be stably adjusted, so as to facilitate subsequent processing operations such as grinding and drilling.

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0017] like Figure 1 , 2 As shown, the device includes a workbench 101, a support 104 fixedly mounted on the upper surface of the workbench 101, a rotating seat 105 rotatably mounted on the upper side of the support 104, two symmetrically distributed clamping frames 106 slidably mounted on the rotating seat 105, and clamping bases 107 fixedly mounted on the upper end of the side of the clamping frame 106 away from the rotating seat 105. Each clamping base 107 has two vertically symmetrically distributed rotating rods 108 rotatably mounted on it, and clamping rods 109 are fixedly sleeved at both ends of the rotating rods 108. Rubber pads 110 are glued and fixedly attached to the side of the clamping base 107 near the vertical center of the support 104, and rubber blocks 111 are sleeved at the ends of the clamping rods 109 near the horizontal center of the clamping base 107.

[0018] like Figure 3 , 4 As shown, a worm gear 201 is fixedly sleeved in the middle of the outer arc surface of the rotating rod 108, and a worm 202 is rotatably mounted in the middle of the clamping seat 107. The worm gear 201 is meshed with the adjacent worm 202 respectively. A servo motor 203 is mounted on the outer side of the clamping seat 107. The output shaft of the servo motor 203 is fixed to the adjacent worm 202 by a coupling.

[0019] like Figure 2 , 3 As shown, each of the clamping frames 106 near the vertical center of the rotating base 105 has a driven plate 204 fixedly installed. The rotating base 105 has two symmetrically distributed guide rails 205 fixedly installed inside, and the guide rails 205 are slidably connected to the driven plate 204. The rotating base 105 has two symmetrically distributed support plates 206 fixedly installed in the middle of its interior. Each support plate 206 has an adjusting screw 207 rotatably installed in the middle of its interior, and the adjusting screw 207 is threadedly connected to the adjacent driven plate 204. A dual-axis motor 208 is fixedly installed between the support plates 206, and the output shaft of the dual-axis motor 208 is fixed to the adjacent adjusting screw 207 through a coupling.

[0020] like Figure 4As shown, a worm gear 209 is fixedly sleeved at the lower end of the rotating seat 105, and a worm 210 is rotatably installed inside the support 104. The worm 210 is meshed with the worm gear 209. A servo motor 211 is installed on the outer side of the support 104. The output shaft of the servo motor 211 is fixed to the adjacent worm 210 by a coupling.

[0021] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the front side of the workbench 101 is provided with multiple door panels 103, each door panel 103 is fixedly provided with a handle, and the lower surface of the workbench 101 is provided with multiple support legs 102.

[0022] In use, the solid-state battery workpiece to be processed is placed on the upper surface of the rotating seat 105. Then, the dual-axis motor 208 is started, causing the output shaft of the dual-axis motor 208 to drive the adjusting screw 207 connected to it to rotate. Then, by adjusting the thread relationship between the adjusting screw 207 and the driven plate 204, the driven plates 204 on both sides are driven to slide between two symmetrically distributed guide rails 205. This causes the driven plates 204 on both sides to move towards each other, causing the clamping frame 106 on both sides to move towards the side closer to the vertical center of the rotating seat 105. This causes the clamping frame 106 to move the clamping seat 107 towards the vertical center of the rotating seat 105, thereby causing the clamping seats 107 on both sides to clamp and fix the solid-state battery workpiece placed on the upper surface of the rotating seat 105 in the horizontal direction. During the clamping and fixing process, the rubber pad 110 on the clamping seat 107 allows the rotating seat 105 to make flexible contact with the solid-state battery workpiece while stably clamping it. Then, the servo motors 203 on both sides are controlled to run, which in turn causes the output shafts of the servo motors 203 to drive the worm gears 202 connected to them to rotate. This, in turn, causes the rotating rods 108 containing the worm gears 201 to rotate through the meshing relationship between the worm gears 201 on the upper and lower sides of the worm gears 202 and the worm gears 201 on the upper and lower sides to rotate synchronously in opposite directions. This, in turn, causes the rotating rods 108 on the upper and lower sides to rotate synchronously in opposite directions. This causes the clamping rods 109 at their ends to rotate around the rotating rods 108, resulting in the clamping rods 109 on the upper and lower sides rotating synchronously in opposite directions. This causes the ends of the clamping rods 109 to approach the upper and lower sides of the solid-state battery workpiece and clamp and fix it vertically. During the clamping and fixing process, the rubber blocks 111 at the ends of the clamping rods 109 ensure that the clamping rods 109 make flexible contact with the solid-state battery workpiece while stably clamping it. During the processing, the servo motor 211 is controlled to run, which causes the output shaft of the servo motor 211 to drive the worm gear 210 connected to it to rotate. Then, through the meshing relationship between the worm gear 210 and the worm wheel 209, the rotating seat 105 where the worm wheel 209 is located is driven to rotate. This causes the rotating seat 105 to drive the clamped solid-state battery workpiece to rotate, thereby stabilizing the placement state of the solid-state battery workpiece and facilitating subsequent processing operations. With the cooperation of servo motor 203, servo motor 211 and dual-axis motor 208, the solid-state battery workpiece can be quickly and stably clamped in the horizontal and vertical directions, and its placement can be stably adjusted, thus facilitating subsequent processing operations such as grinding and drilling.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
