[0043] S1. Place multiple metal discs sequentially onto the lower extrusion groove 101;
[0044] S2. Start the two telescopic rods 106 to drive the upper extrusion plate 107 to move downward through the linkage frame plate 105;

[0047] According to the instruction manual Figure 1 In detail, the battery electrode in step five is the positive electrode of the battery.
[0048] According to the instruction manual Figure 1 In detail, the raw material in step one is stainless steel.
[0049] According to the instruction manual Figure 1 In detail, the heat fusion process in step two requires the use of a heat fusion machine.
[0050] According to the instruction manual Figure 1 In detail, the outer surface of the metal cylinder in step three needs to be polished.
[0051] According to the instruction manual Figure 1 In detail, the cutting process in step four requires the use of a circular saw.
[0052] According to the instruction manual Figure 1 In detail, the thickness of the metal disc in step four is 2mm.
[0053] According to the instruction manual Figure 1 In detail, the groove extrusion device can extrude metal discs of different diameters.
[0054] According to the instruction manual Figure 3-10 The detailed description is a detailed description of the groove extrusion device;
[0055] The lower extrusion groove 101 is fixedly connected to the supporting horizontal plate 102 by threads. The supporting horizontal plate 102 is fixedly connected to the bottom support plate 103 by welding. Two limiting sliding columns 104 are fixedly connected to the bottom support plate 103 by welding. A linkage frame plate 105 is slidably connected to the two limiting sliding columns 104 through two round holes. Two telescopic rods 106 are fixedly connected to the linkage frame plate 105 through flange plates. Both telescopic rods 106 are fixedly connected to the bottom support plate 103 through flange plates. An upper extrusion protrusion plate 107 is fixedly connected to the linkage frame plate 105 by threads.
[0056] Furthermore, the lower extrusion groove 101 is provided with a groove. When the metal disc is pressed into the groove on the lower extrusion groove 101, the processing of the positive electrode of the battery with the groove can be completed. The supporting plate 102 provides a fixed space for the lower extrusion groove 101. The lower extrusion groove 101 is easy to disassemble, and different lower extrusion grooves 101 can be replaced. The bottom support plate 103 plays a supporting and fixing role, so that the device can be placed stably on the ground. The bottom support plate 103 provides a fixed space for the two limiting sliding columns 104, and the two limiting sliding columns 104 provide sliding space for the linkage frame plate 105 and limit its movement. The linkage frame plate 105 can only slide up and down, and the linkage frame plate 105 can provide a fixed space for the upper extrusion protrusion plate 107. After the two telescopic rods 106 are activated, the linkage frame plate 105 can be driven to rise and fall, which in turn drives the upper extrusion protrusion plate 107 to rise and fall, so that the upper extrusion protrusion plate 107 contacts the lower extrusion groove 101. The lower extrusion groove 101 is provided with a groove, and the upper extrusion protrusion plate 107 is provided with a protrusion. The protrusion on the upper extrusion protrusion plate 107 and the groove on the lower extrusion groove 101 cooperate with each other. By using the protrusion on the upper extrusion protrusion plate 107 to slide into the groove on the lower extrusion groove 101, the extrusion process of the metal disc can be realized.
[0057] Multiple metal discs are placed sequentially on the lower extrusion groove 101. The two telescopic rods 106 are activated to move the linkage frame plate 105 downward. The linkage frame plate 105 will then move the upper extrusion protrusion plate 107 downward, so that the upper extrusion protrusion plate 107 contacts the lower extrusion groove 101, thus completing the extrusion process of the metal discs. Depending on the diameter of the metal discs, different lower extrusion grooves 101 and upper extrusion protrusion plates 107 can be replaced to extrude multiple metal discs of different sizes, thereby completing the manufacturing of positive electrodes for different types of batteries.
[0058] Two vertical sliding columns 201 are fixedly connected to the bottom support plate 103 by welding. Each vertical sliding column 201 is fitted with a spring. A bearing support plate 202 is slidably connected to the two vertical sliding columns 201 through two round holes. The top of each spring is in contact with the bearing support plate 202. The bearing support plate 202 is in contact with the linkage frame plate 105. Two horizontal rotating square shafts 203 are rotatably connected to the bearing support plate 202 through shafts. Two transmission belt rollers 204 are slidably connected to each of the two horizontal rotating square shafts 203 through square openings. The four transmission belt rollers 204 are divided into front and rear groups. A transmission belt 205 is connected between the two groups of two transmission belt rollers 204.
[0059] Furthermore, the two vertical sliding columns 201 provide sliding space for the bearing support plate 202. A limiting circular plate is fixedly connected above each of the two vertical sliding columns 201 to limit the bearing support plate 202 and prevent it from detaching from the two vertical sliding columns 201. The two vertical sliding columns 201 also provide space for the two springs to be fitted onto each other. The elastic force generated by the two springs acts on the bearing support plate 202, placing it at the top. The bearing support plate 202 provides rotation space for the two horizontal rotating square shafts 203. The square shaft 203 provides sliding space for two sets of two drive belt rollers 204 and drives them to rotate. The two sets of two drive belt rollers 204 provide transmission space for two conveyor belts 205. These conveyor belts 205 can move multiple metal discs, sequentially transferring them to the area directly above the lower extrusion groove 101. When the bearing support plate 202 is at its highest position, the upper surfaces of the two conveyor belts 205 are higher than the lower extrusion groove 101, allowing multiple metal discs to be sequentially placed onto the two conveyor belts. Between belts 205, the two horizontal rotating square shafts 203 are intermittently rotated. These intermittently rotating shafts 203 drive the two conveyor belts 205 intermittently via two sets of two transmission belt rollers 204. When a metal disc moves directly above the lower extrusion groove 101, the two horizontal rotating square shafts 203 stop rotating. At this time, the two telescopic rods 106 retract and drive the linkage frame plate 105 downwards. The linkage frame plate 105 then drives the bearing support plate 202 downwards, causing the metal disc located between the two conveyor belts 205 to fall. The metal disc falls onto the lower extrusion groove 101. When the linkage frame plate 105 continues to fall, the upper extrusion protrusion 107 can extrude the metal disc on the lower extrusion groove 101. After extrusion, the two telescopic rods 106 will return to their original positions. At this time, the elastic force generated by the two springs acts on the bearing support plate 202, which eventually drives the two conveyor belts 205 to move upward, thereby moving the extruded metal disc upward and separating it from the lower extrusion groove 101. By repeating the above steps, the extrusion of multiple metal discs can be completed.
[0060] Two geared motors 301 are fixedly connected to the bearing support plate 202 via flange plates. The output shafts of the two geared motors 301 are fixedly connected to the two horizontal rotating square shafts 203 via keyways and snap rings.
[0061] Furthermore, the two geared motors 301 are controlled by the same switch to ensure that the two geared motors 301 can rotate simultaneously in the same direction, ultimately driving the two horizontal rotating square shafts 203 to rotate. The two geared motors 301 start intermittently, rotating for a period of time and then stopping for a period of time, ultimately driving multiple metal discs to move. When they stop, they squeeze the metal discs, and then drive the metal discs to move again, and so on, to complete the squeezing process of multiple metal discs.
[0062] Both of the horizontal rotating square shafts 203 are rotatably connected to bidirectional lead screws 401 via bearing seats, and the two bidirectional lead screws 401 are respectively connected to the two transmission belt rollers 204 via threaded transmission.
[0063] Furthermore, the threads at both ends of the bidirectional lead screw 401 rotate in opposite directions. Rotating the bidirectional lead screw 401 can drive the two transmission belt rollers 204 to slide inward or outward simultaneously, thereby changing the distance between the two transmission belts 205. Depending on the size of the lower extrusion groove 101 and the upper extrusion protrusion 107, the distance between the two transmission belts 205 is changed, ensuring that the two transmission belts 205 can drive multiple metal discs of different diameters to move.
