[0002] With the increasing global demand for clean energy, battery technology, as a key supporting field, is undergoing rapid transformation and development. Lithium-ion batteries, with their advantages of high energy density and long cycle life, have been widely used in electric vehicles, consumer electronics, and other fields. However, traditional liquid lithium-ion batteries have safety hazards such as electrolyte leakage and poor thermal stability, which limit their further development and application scope. Solid-state batteries, as a new generation of battery technology, replace traditional liquid electrolytes with solid electrolytes, effectively solving the safety problems of liquid batteries. At the same time, they have higher energy density and power density, making them a research hotspot and development direction in the current battery field. In the production process of lithium germanium phosphorus sulfur solid-state batteries, the preparation and processing of cathode materials is one of the key links affecting battery performance, and the cathode cutting device is an important piece of equipment for cathode processing.

[0003] However, in the use of existing positive electrode cutting devices, the clamps are difficult to adapt to positive electrode materials of different sizes. The positive electrode materials are prone to displacement or shaking during cutting, resulting in inaccurate cutting positions and difficulty in ensuring dimensional accuracy, which ultimately affects the assembly and performance of the battery. Utility Model Content

[0004] The purpose of this invention is to provide a cathode cutting device for lithium germanium phosphorus sulfur solid-state battery processing. By setting up a clamping mechanism, it solves the problem that in the existing cathode cutting device, the clamping plate is difficult to adapt to cathode materials of different sizes, and the cathode material is prone to displacement or shaking during cutting, resulting in inaccurate cutting position, difficulty in guaranteeing dimensional accuracy, and ultimately affecting the assembly and performance of the battery.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a cutting device for the positive electrode of lithium germanium phosphorus sulfur solid battery processing, including a rectangular support plate, on which two clamping mechanisms and an adjustment mechanism are provided;

[0007] The clamping mechanism includes an inverted bracket fixedly connected to the top of a rectangular support plate. Two sliding grooves are formed on the inverted bracket. A clamping plate is provided below the inverted bracket. Sliding rods are fixedly connected to the front and rear sides of the clamping plate. The two sliding rods pass through the two sliding grooves on opposite sides and are slidably connected to the two sliding grooves. The adjusting mechanism includes two support plates fixedly connected to the bottom of the rectangular support plate. A bidirectional threaded rod is rotatably connected between the two support plates. The left side of the bidirectional threaded rod passes through the support plate located on the left side.

[0008] Furthermore, a pull rod is fixedly connected to the top of the clamping plate, the top of the pull rod passes through the C-shaped support frame, the pull rod is slidably connected to the C-shaped support frame, and a handle is fixedly connected to the top of the pull rod.

[0009] Furthermore, two spring telescopic rods are fixedly connected to the top of the clamping plate, and the tops of both spring telescopic rods are fixedly connected to the U-shaped support frame.

[0010] Furthermore, the top of the rectangular support plate has two slots, and the bottom of the handle is hinged with two connecting rods, the ends of which extend into the two slots respectively.

[0011] Furthermore, a motor sleeve is fixedly connected to the left side of the support plate located on the left side, and a motor is fixedly connected to the inner wall of the motor sleeve. The output shaft of the motor is fixedly connected to a bidirectional threaded rod through a coupling.

[0012] Furthermore, two rectangular sliding grooves are provided on the rectangular support plate, and two connecting blocks are threadedly connected to the outer wall of the bidirectional threaded rod. The side of each connecting block away from the bidirectional threaded rod passes through the rectangular sliding groove located on the front side and is fixedly connected to the two C-shaped support frames respectively. Both connecting blocks are slidably connected to the rectangular sliding groove.

[0013] Furthermore, a slide rod 2 is fixedly connected between the two support plates, and two connecting blocks 2 are slidably connected to the outer wall of the slide rod 2. The side of each connecting block 2 away from the slide rod 2 passes through a rectangular slide groove located on the rear side and is fixedly connected to two C-shaped support frames respectively. Both connecting blocks 2 are slidably connected to the rectangular slide groove.

[0014] Furthermore, a base is fixedly connected to the bottom of the rectangular support plate, and a tool collecting box is fixedly connected to the top of the base, with cutting tools disposed inside the tool collecting box.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up the clamping mechanism, after adjusting the distance between the two clamping plates, the handle can be pulled again to continue moving the clamping plates upward. During this process, the spring telescopic rod will be compressed. When the spring on the telescopic rod is compressed, it will undergo elastic deformation and generate elastic force. Then, the connecting rod is bent to be parallel with the handle and the handle is released. At this time, the clamping plate will move downward under the action of the elastic force of the spring telescopic rod, stably clamping the positive electrode material. This allows the clamping plate to apply a stable and continuous pressure to the positive electrode material, ensuring that the positive electrode material will not loosen or shift due to external interference during the cutting process. This improves the cutting accuracy and quality, ensures that the dimensions of the cut positive electrode material meet the standards, reduces the defect rate, and the elastic deformation of the spring can adapt to changes in the thickness of the material, ensuring stable clamping regardless of the material thickness.

[0017] 2. By setting an adjustment mechanism, when it is necessary to clamp the gap between the two clamping plates, the handle can be pulled to move the clamping plates upward via the pull rod. At this time, the two connecting rods are moved so that their ends are engaged in the slots. Then, the motor is started according to the size of the positive electrode material to be cut. The motor will drive the two connecting blocks one to move closer or further apart through the bidirectional threaded rod. At this time, the two C-shaped support frames will move closer or further apart with the cooperation of the sliding rod two and the connecting block two until both clamping plates are moved to the optimal position to clamp the positive electrode material. This prevents problems such as unstable clamping and material shaking caused by size mismatch, and ensures that the position of the positive electrode material is fixed during the cutting process. This is beneficial to improving the cutting accuracy and quality. The clamping plates can be fixed before adjusting the clamping plate gap. When adjusting according to the size of the positive electrode material later, it can avoid friction between the clamping plates and the rectangular support plates, and avoid wear on the clamping plates during adjustment.

Find the optimal position for clamping the positive electrode material, and then pull the handle 217 again to continue moving the clamping plate 213 upward. During this process, the spring telescopic rod 218 will be compressed. When the spring on the spring telescopic rod 218 is compressed, it will undergo elastic deformation and generate elastic force.

At this time, the clamping plate 213 will move downward under the action of the elastic force of the spring telescopic rod 218, and stably clamp the positive electrode material. After clamping, take out the cutting knife from the delivered knife collection box and cut the positive electrode material.
