Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid-state battery technology, and more specifically to a solid-state battery electrode stacking device. Background Technology
[0002] Existing liquid lithium-ion batteries mainly consist of three components: a positive electrode, a separator, and a negative electrode. To avoid direct contact between the positive and negative electrodes, which could lead to short circuits and to maximize the utilization of both electrodes, the separator must be larger than the negative electrode, and the negative electrode must be slightly larger than the positive electrode. Therefore, it is necessary to avoid directly stacking multiple sets of solid-state battery electrodes together. Existing solid-state battery electrode stacking devices are not convenient for fixing the placed solid-state battery electrodes, and are prone to shaking and displacement. This can lead to damage or deformation during electrode transportation, increasing production costs, reducing production efficiency, and lowering battery safety. Chinese patent (CN222647150U) discloses a "Solid-State Battery Electrode Stacking Device." This invention uses protective plates that move inward to clamp and fix the solid-state battery electrodes placed between multiple sets of separators, preventing shaking and displacement, avoiding damage or deformation during electrode transportation, reducing production costs, improving production efficiency, and enhancing battery safety.
[0003] However, existing stacking devices have defects: for example, the protective plate cannot be embedded inside several separators during use. When the battery electrode is too small to protrude from both sides of the separator, the protective plate will be blocked by both sides of the separator and cannot contact the electrode for clamping, thus failing to achieve a good clamping and fastening effect. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a solid-state battery electrode stacking device to solve the problem that the protective plate used by the traditional stacking device in the background art to clamp the battery electrode is difficult to achieve a good clamping effect for electrodes with small size.
[0005] This utility model provides the following technical solution: a solid-state battery electrode stacking device, including a storage frame, a plurality of partitions fixedly installed inside the storage frame, clamping mechanisms provided on both sides of the storage frame, the clamping mechanisms including an adjustment mechanism, a plurality of moving arms, and a plurality of protective clamps, the plurality of moving arms being divided into two groups and distributed on the front and back of the partitions, the protective clamps being fixedly connected to the side walls of the plurality of moving arms, the adjustment mechanism being used to control the opposite displacement of the two groups of moving arms, the side of the protective clamps facing the moving arms being set as a slope, and the plurality of partitions and the plurality of vertically arranged protective clamps being staggered.
[0006] Furthermore, some of the protective clamps are configured with a downward sloping surface on the side facing the partition.
[0007] Furthermore, the adjustment mechanism includes a plurality of threaded rods and a central column. The plurality of threaded rods are arranged in two groups, and the central column is positioned between the two groups of threaded rods. A driven bevel gear is fixedly connected to one end of each threaded rod facing the central column. A plurality of driven bevel gears are fixedly connected to the side wall of the central column. The driven bevel gears are distributed and mesh with the driven bevel gears at one end of each of the two groups of threaded rods. A sleeve is rotatably fitted onto the side wall of each threaded rod. The sleeves are fixedly connected to the side wall of the storage frame. Two sets of movable arms are threadedly fitted onto the side walls of the two sets of threaded rods respectively. End plates are rotatably fitted onto both ends of the central column. Two end plates are fixedly connected to the side wall of the storage frame. A motor is fixedly installed at the bottom of one end plate, and the output shaft of the motor passes through the end plate and connects to the end face of the central column.
[0008] Furthermore, the front and back of the storage frame are provided with several sliding grooves, and the two sets of moving arms are respectively slidably connected in the several sliding grooves on the front and back of the storage frame.
[0009] Furthermore, the movable arm includes an end arm and a flip arm, which are connected by a hinge. The flip arm has a locking fastener inside, and the side wall of the end arm has a locking groove that penetrates into the interior.
[0010] Furthermore, the locking component includes a rotating pin, which is rotatably sleeved inside the flip arm. One end of the rotating pin is fixedly connected to a locking plate, and the other end of the rotating pin is fixedly connected to a rotating handle. The locking groove includes an embedding groove, the height of which is greater than the diameter of the rotating pin, and a locking slot is formed inside the embedding groove.
[0011] Furthermore, the rotating column sidewall is provided with an enlarged diameter wall, and the flip arm inner wall is provided with an enlarged diameter groove, with the enlarged diameter wall of the rotating column sidewall embedded in the enlarged diameter groove of the flip arm.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] This invention, through the cooperation of an adjustment mechanism, several moving arms, and several protective clamps, allows the clamping mechanism to be embedded in the gaps between several partitions. This avoids the problem of the partitions blocking the clamping mechanism when the battery electrode is small, preventing the battery electrode from being fixed. The device clamps and fixes the battery electrode through the protective clamps. The shape design of the protective clamps not only clamps the battery electrode but also applies downward pressure, thereby further improving the stability of the battery electrode.

[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] Reference Figure 1 and Figure 2 This utility model provides a solid-state battery electrode stacking device, including a storage frame 1, with several partitions 2 fixedly installed inside the storage frame 1. Clamping mechanisms are provided on both sides of the storage frame 1. The clamping mechanisms include an adjustment mechanism 3, several moving arms 4, and several protective clamps 5. The moving arms 4 are divided into two groups and distributed on the front and back of the partitions 2. Protective clamps 5 are fixedly connected to the side walls of the moving arms 4. The adjustment mechanism 3 is used to control the opposite displacement of the two groups of moving arms 4. The side of the protective clamps 5 facing the moving arms 4 is set as a slope. The partitions 2 and the vertically arranged protective clamps 5 are staggered.
[0023] In use, several battery electrodes are placed on top of several partitions 2. Then, the clamping mechanisms on both sides of the storage frame 1 can fix the battery electrodes placed on top of the partitions 2. During the process, the adjustment mechanism 3 can drive the two sets of moving arms 4 to move in opposite directions, thereby causing several protective clamps 5 to clamp the battery electrodes. Since the vertically arranged protective clamps 5 are staggered with the partitions 2, the protective clamps 5 can be embedded in the gaps between the partitions 2 to clamp the battery electrodes, thus avoiding the partitions 2 from blocking the protective clamps 5.
[0024] Reference Figure 3 Several protective clamps 5 are set to a downward slope on the side facing the partition 2.
[0025] When the protective clamp 5 clamps the battery electrode placed on top of the separator 2, the slope of the protective clamp 5 allows it to clamp and fix the battery electrode while applying downward pressure, thereby improving stability and firmness.
[0026] Reference Figure 2 The adjusting mechanism 3 includes several threaded rods 31 and a central column 32. The threaded rods 31 are divided into two groups, and the central column 32 is located between the two groups of threaded rods 31. A passive bevel gear 35 is fixedly connected to one end of each threaded rod 31 facing the central column 32. Several active bevel gears 36 are fixedly connected to the side wall of the central column 32. The active bevel gears 36 are distributed and mesh with the passive bevel gears 35 at one end of each of the two groups of threaded rods 31. A sleeve 37 is rotatably sleeved on the side wall of each threaded rod 31. The sleeve 37 is fixedly connected to the side wall of the storage frame 1. Two sets of moving arms 4 are threadedly sleeved on the side walls of the two sets of threaded rods 31 respectively. End plates 33 are rotatably sleeved on both ends of the central column 32. The two end plates 33 are fixedly connected to the side wall of the storage frame 1. A motor 34 is fixedly installed at the bottom of one end plate 33. The output shaft of the motor 34 passes through the end plate 33 and is connected to the end face of the central column 32.
[0027] In use, the motor 34 drives the central column 32 to rotate, which in turn drives several active bevel gears 36 to rotate. Under the meshing action of the active bevel gears 36 and the passive bevel gears 35, the two sets of threaded rods 31 rotate. The effect of the threaded structure allows the two sets of moving arms 4 to move. The opposite displacement of the two sets of moving arms 4 can be controlled by setting the thread direction of the sidewalls of the two sets of threaded rods 31.
[0028] Reference Figure 1 , 2 The front and back of the storage frame 1 are provided with several sliding grooves, and the two sets of moving arms 4 are respectively slidably connected in the several sliding grooves on the front and back of the storage frame 1.
[0029] This setting prevents the moving arm 4 from wobbling due to the rotation of the threaded rod 31 during the operation of the adjusting mechanism 3.
[0030] Reference Figure 4 The movable arm 4 includes an end arm 41 and a flip arm 42. The end arm 41 and the flip arm 42 are connected by a hinge 43. The flip arm 42 is provided with a locking fastener 44 inside, and the side wall of the end arm 41 is provided with a locking groove 45 that penetrates into the interior.
[0031] This setting allows the flip arm 42 to be flipped so that the moving arm 4 has a folding effect, avoiding the obstruction effect of the protective clamp 5 when placing the battery electrode on the top of the partition 2. By flipping the flip arm 42, the flip arm 42 and the end arm 41 are made to be vertical, thereby avoiding the obstruction of the moving arm 4 when the battery electrode is placed. Furthermore, by cooperating with the locking fastener 44 and the locking groove 45, the flip arm 42 can be flipped and locked to prevent the moving arm 4 from being passively folded when subjected to force.
[0032] Reference Figure 5 The locking fastener 44 includes a rotating pin 441, which is rotated and sleeved inside the flip arm 42. One end of the rotating pin 441 is fixedly connected to a locking plate 442, and the other end of the rotating pin 441 is fixedly connected to a rotating handle 443. The locking groove 45 includes an embedding groove 451, the height of which is greater than the diameter of the rotating pin 441, and a locking groove 452 is provided inside the embedding groove 451.
[0033] When the end arm 41 and the flip arm 42 are flipped to the horizontal position, one end of the rotating column 441 and the locking plate 442 enter the locking groove 45. During this process, the locking plate 442 is in a horizontal position and enters the locking groove 452 from the embedding groove 451. Then, by rotating the handle 443, the rotating column 441 is driven to rotate, and the rotating column 441 drives the locking plate 442 to rotate, so that the locking plate 442 changes from a horizontal position to a vertical position. This allows the locking plate 442 to be locked into the locking groove 45 to achieve a fixed effect, thereby flipping and locking the flip arm 42.
[0034] Reference Figure 6 The side wall of the rotating column 441 is provided with an enlarged diameter wall, and the inner wall of the flap arm 42 is provided with an enlarged diameter column groove. The enlarged diameter wall of the side wall of the rotating column 441 is embedded in the enlarged diameter column groove of the flap arm 42.
[0035] This setting prevents the rotating column 441 from detaching from the tilting arm 42.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
