[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the copper-aluminum composite plate is fed into a cutting machine, the cutting machine is started, and the cutting machine cuts the copper-aluminum composite plate into blank plates according to a preset size. After the cutting is completed, the transfer robot transports the cut blank plates to a grinder, and the grinder grinds the blank plates.

[0017] 2. In the present invention, a stamping and forming device for the negative pole of an automobile battery is designed, and a conveying mechanism in the device is used to transport the blank plate. During the conveying process of the blank plate, the high-speed airflow ejected from the air outlet channel will blow away the dust and other debris attached to the blank plate.

[0018] 3. In the present invention, a stamping and forming device for the negative pole of an automobile battery is designed, and a flushing mechanism in the device is used to flush the blank plate.

[0026] Press the electronic button 220, the electronic button 220 starts the air inlet fan 208 and the conveying belt 201, the terminal 215 is connected with the high-voltage power supply by the wire, the high-voltage current flows into the positive plate 210 and the negative plate 211 through the terminal 215, the high-voltage electric field is generated between the positive plate 210 and the negative plate 211, the air inlet fan 208 sends the external air into the air inlet box 207, the air will pass through the filter screen 213 first, the filter screen 213 can remove the larger impurities in the air, the air flows into the positive plate 210 and the negative plate 211 after passing through the filter screen 213, the high-voltage electric field between the positive plate 210 and the negative plate 211 can make the water molecules in the air ionize, thereby generating a large number of positive and negative ions, the positive and negative ions will adhere to the smaller dust in the air, so that the dust is charged, the charged dust is close to the positive plate 210 and the negative plate 211 under the action of the electric field force, and is attached to the dust collecting plate 212, the air without dust and impurities flows into the air inlet channel 203 along the air inlet pipe 216, the airflow in the air inlet channel 203 can push the sliding plate 205 to rotate upward, the upward rotating sliding plate 205 no longer seals the air inlet channel 203, the high-speed airflow is sprayed from the air inlet channel 203 and discharged along the air outlet channel 217, and at the same time, the electronic button 220 starts the electric push rod 219, the electric push rod 219 can push the limiting strip 218 to move outward; After the grinding is completed, the blank plate is slid out of the grinder 3 and enters the flushing tank 401 along the feeding channel 402. The blank plate entering the flushing tank 401 falls on the moving seat 403. The controller 421 starts the push-pull electromagnet 409. The push-pull electromagnet 409 drives the ejector rod 408 to move outward. The outward moving ejector rod 408 clamps the blank plate. The controller 421 starts the driving motor 406. The driving motor 406 drives the winding shaft 405 to rotate. The rotating winding shaft 405 releases the winding traction rope 404. The traction rope 404 no longer pulls the moving seat 403. The pulling spring 407 drives the moving seat 403 and the blank plate to move leftwards, so that the blank plate moves to the position directly below the liquid inlet pipe 416. The controller 421 opens the electromagnetic valve 418 in the liquid inlet pipe 416. The cleaning agent is injected into the moving seat 403 along the liquid inlet pipe 416. When the cleaning agent completely covers the blank plate, the controller 421 closes the electromagnetic valve 418 in the liquid inlet pipe 416 and starts the ultrasonic generator 424. The ultrasonic generator 424 converts electric energy into high-frequency alternating current signals matched with the ultrasonic transducer 411 and inputs the high-frequency alternating current signals into the ultrasonic transducer 411. The ultrasonic transducer 411 converts the high-frequency alternating current signals into ultrasonic signals and sends the ultrasonic signals into the cleaning agent. When the ultrasonic waves propagate in the cleaning agent, due to the nonlinear effect, acoustic cavitation is generated. The impact wave generated when the cavitation bubble suddenly closes can generate thousands of atmospheric pressures around it. The direct and repeated impact on the contaminated layer can damage the adsorption of the contaminants and the surface of the blank plate and also cause the contaminants to separate from the surface of the blank plate and disperse into the cleaning liquid. At the same time, for the oil and grease contaminants on the surface of the blank plate, due to the ultrasonic cavitation effect, the two liquids are rapidly dispersed and emulsified at the interface. The solid particles fall off. The cavitation bubbles can make the liquid itself circulate during the vibration process. There is a high velocity gradient and viscous stress on the surface of the vibrating bubbles, which promotes the damage and falling off of the contaminants on the surface of the blank plate. Thus, the blank plate is cleaned. After the cleaning is completed, the controller 421 opens the electromagnetic valve 418 in the liquid outlet pipe 417. The cleaning agent carrying the impurities flows out along the liquid outlet pipe 417 and the drain hole 414. After the cleaning agent completely flows out, the driving motor 406 drives the winding shaft 405 to rotate reversely. The reversely rotating winding shaft 405 retracts the traction rope 404. The retracted traction rope 404 pulls the moving seat 403 to move rightwards to the position below the infrared heating pipe 420. The controller 421 starts the infrared heating pipe 420. The infrared heating pipe 420 heats and dries the blank plate in the moving seat 403. After the drying is completed, the controller 421 starts the micro push rod 419. The micro push rod 419 drives the gate plate 413 to move inward. The inward moving gate plate 413 no longer blocks the blank plate. At the same time, the controller 421 closes the push-pull electromagnet 409. The push-pull electromagnet 409 drives the ejector rod 408 to move inward. The inward moving ejector rod 408 no longer clamps the blank plate. The blank plate slides into the discharging channel 423 along the through slot 412. The blank plate slides along the discharge channel 423 to the conveying belt 201, and the conveying belt 201 drives the blank plate to move. When the blank plate moves, the high-speed airflow sprayed by the air inlet channel 203 blows away the dust on the surface of the blank plate. The flowing high-speed airflow forms an air curtain above the blank plate, preventing dust above from falling down. At the same time, the limiting strip 218 abuts against the blank plate, preventing the blank plate from deviating on the conveying belt 201. The conveying belt 201 conveys the blank plate into the punch 1; The punch die is placed into the punch 1, and the punch 1 sends the blank plate into the first punch die for punching. According to the pressure of aluminum, the copper layer part of the blank plate is extruded and formed, so that the size of the copper layer part is increased. The punch 1 uses the second punch die to punch the copper layer part with increased size, so that the diameter of the copper layer part is increased. The third punch die is used to punch the copper layer part, so that the diameter of the copper layer part is greater than the original diameter, and the punching of the intermediate small hole and the punching of the step size are completed at the same time. The punch 1 sends the material punched for three times into the fourth punch die for excess material cutting. The material is punched to the size of the finished product, and the negative pole post finished product is obtained.
