One side of the horizontal plate of each L-shaped guide plate 20 is fixedly connected to the frame of the roller conveyor 2, and the other side extends horizontally to be suspended above the roller of the roller conveyor 2. The vertical plate of the L-shaped guide plate 20 is vertically fixed above the suspended end of the horizontal plate of the L-shaped guide plate 20. Specifically, the vertical plate of the L-shaped guide plate 20 should be lower than the height of the lead-acid battery pole placed horizontally on the roller conveyor 2, so that the vertical plates of the two L-shaped guide plates 20 can only limit the lead-acid battery in the width direction without being affected by the pole. The two L-shaped guide plates 20 will limit the lead-acid battery The lead-acid batteries are restricted to be transported to the rear side in the middle of the roller conveyor 2 to prevent the lead-acid batteries from shifting sideways during transportation, so that the cutter can accurately cut from the boundary line between the battery shell and the battery cover. Two vertical guide plates are installed at the front end of the two L-shaped guide plates 20. The two guide plates are inclined outward so that the lead-acid batteries transported on the roller conveyor 2 can be guided by the two guide plates to smoothly enter between the two L-shaped guide plates 20, so that the lead-acid batteries can maintain directional transportation, which is convenient for cutting and separating the battery shell and the battery cover. Of course, an operator can be arranged to supervise the position to prevent the battery from being obstructed in transportation and adjust the battery position in time to ensure smooth transportation of the battery.

During the machine selection process, the mechanical parameters of each device can be queried and calculated through the mechanical design manual, and equipment of corresponding specifications can be purchased appropriately, and only the starting sequence and start and stop time need to be programmed and set.

[0052] It can be seen from the above technical solution that when in use, the lead-acid battery is placed horizontally on the roller conveyor 2 so that the pole of the lead-acid battery is located on one side of the roller conveyor 2 ( Figure 2 , 3The PLC controller controls the roller conveyor 2 to bring the lead-acid battery into the collecting cover 22 from the inlet and outlet 221 at the front end. The controller controls the cylinder 23 to drive the puncture tube 24 to vertically penetrate the battery shell of the lead-acid battery. Then the cylinder 23 drives the puncture tube 24 to move upward, so that the conical tip 241 of the puncture tube 24 is retracted into the battery shell. The air pump 27 supplies air to the air supply hose 26. The gas enters the puncture tube 24 and enters the battery shell from the exhaust hole 242, so that high pressure is generated in the battery shell, and the acid in the battery shell is quickly discharged from the puncture hole at the bottom thereof to increase the acid discharge speed. The acid is discharged into the acid collection tank 25. After the acid discharge is completed, the cylinder 23 drives the puncture tube 24 to move upward. The thorn tube 24 moves upward to remove the battery shell, and the battery goes out from the inlet and outlet 221 at the rear end of the collecting cover 22 through the roller conveyor 2, and continues to be transported to the rear end and unloaded into the U-shaped movable seat 42. The pressure plate 45 is driven by the hydraulic cylinder 46 to fix the battery shell of the battery in the U-shaped movable seat 42. The first hydraulic cylinder 35 drives the movable frame 32 to move horizontally, so that the cutter 31 is aligned with the cutting position of the battery cover and the battery shell of the battery in the longitudinal direction (because the battery has been guided and positioned in the transverse direction by the L-shaped guide plate 20 during the transportation process, and the cutting accuracy of the battery cover and the battery shell is not too high, the cutter 31 can be aligned with the cutting position in the longitudinal direction to achieve rapid cutting and separation). 38 drives the cutter 31 to move longitudinally to align with the cutting position of the battery for cutting and separation. The cut and separated battery cover slides along the discharge plate 44 into the cleaning tank 5 for cleaning. The battery shell cut on the U-shaped movable seat 42 is driven to rotate by the first driving mechanism 43 so that the opening of the battery shell faces downward, and the plate is poured out of the battery shell. The plate falls from the two discharge plates 44 onto the first belt conveyor 101 and is transported to the smelting workshop. Then, the battery shell cut on the U-shaped movable seat 42 is driven to rotate to an inclined position by the first driving mechanism 43, and the pressing plate 45 is driven by the hydraulic cylinder 46 to release the battery shell. The battery shell slides onto the discharge plate 44 and is introduced into the cleaning tank 5 for cleaning the battery shell. In the process of inclined transportation by the second belt conveyor 7 in the cleaning tank 5, the battery shell is sprayed by the nozzle 53. At the same time, the battery shell is briefly intercepted by the swing plate 54, so that the battery shell is turned over and cleaned under the interception effect of the swing plate 54 during the inclined transportation process. After a certain period of cleaning, the lower end of the swing plate 54 is pulled upward by the electric push rod 56 to release the intercepted battery shell, so that the battery shell continues to be obliquely transported to the crushing box 6 through the second belt conveyor 7. At the same time, the battery cover is transported and cleaned in another cleaning tank 5. After cleaning, it is also transported to the crushing box 6 for crushing. The crushed battery fragments are transported and discharged from the discharge port 61 by the screw conveyor 9 for subsequent processing.
