[0018] The present invention will be further described below in conjunction with the accompanying drawings and the implementation mode.

[0019] Please refer to Figures 1 - 6 , in the present invention, the lithium battery virtual soldering detection device includes a frame-shaped plate 3 fixedly installed on the top of the bottom plate 1. The frame-shaped plate 3 is installed on the top of the bottom plate 1 through two U-shaped mounting plates 2. An ultrasonic flaw detector 4 is fixedly installed on the inner wall of the top of the frame-shaped plate 3. Adjusting rods 5 are respectively rotatably installed on the outer walls of both sides of the frame-shaped plate 3. In order to prevent people from slipping when rotating the adjusting rods 5 and affecting the work efficiency, anti-slip sleeves are respectively fixedly sleeved on the two adjusting rods 5.

Under the action of the compression springs 10, the two U-shaped placement plates 6 are pushed to approach each other to clamp and fix the lithium battery circuit board. Connecting rods 9 are respectively fixedly installed at one ends of the two connecting plates 8 close to each other.

A horizontal pipe 16 is fixedly installed at the top end of the vertical pipe 20, and a plurality of air collecting hoods 17 are fixedly installed on the horizontal pipe 16. Through the strong suction generated by the suction fan 15, the debris and dust generated by the back welding on the lithium battery circuit board are adsorbed into the suction fan 15 through the air collecting hoods 17, the horizontal pipe 16, the vertical pipe 20, the sealing pipe 19, and the connecting pipe 18, so as to complete the cleaning of the debris and dust on the lithium battery circuit board and improve the accuracy of the subsequent detection results.

[0020] In order to enable the lithium battery circuit board to quickly reach a horizontal state when being rolled up, facilitating subsequent dust cleaning and solder joint inspection operations, bracelet-shaped ring grooves 11 are respectively formed on two adjusting rods 5, and spherical balls 13 are respectively and movably installed in the two bracelet-shaped ring grooves 11. Connecting ropes 12 are respectively and fixedly installed on the two spherical balls 13, and conical gravity blocks 14 are respectively and fixedly installed at the bottom ends of the two connecting ropes 12.

[0021] In order to limit the connecting plate 8, so that the rotation of the connecting plate 8 drives the rotation of the adjusting rod 5, limiting grooves are respectively formed on the inner walls of the two grooves 7, and the two sides of the two connecting plates 8 respectively extend into the two limiting grooves and are respectively in sliding connection with the inner walls of the two limiting grooves.

[0022] In order to more completely adsorb debris and dust, a driven gear 21 is fixedly sleeved on the vertical pipe 20. A vertical plate 25 is placed on the top of the frame-shaped plate 3. Two sliding rods 24 are respectively and slidably installed on the two vertical plates 25, and the four sliding rods 24 are all fixedly connected to the sealing pipe 19. Limiting plates 26 are respectively arranged on the outer walls of the two sides of the two vertical plates 25, and the two limiting plates 26 are respectively fixedly connected to the four sliding rods 24. Rotating rods 23 are respectively and rotatably installed at the tops of the two vertical plates 25. Driving gears 22 and first belt pulleys 29 are respectively and fixedly sleeved on the two rotating rods 23, and the two driving gears 22 are both meshed with the driven gear 21. Two collecting water tanks 30 are fixedly installed on the top of the bottom plate 1. Two air outlet pipes 32 are fixedly installed at the air outlet of the air suction fan 15, and the other ends of the two air outlet pipes 32 respectively extend into the two collecting water tanks 30. Sewage discharge pipes are respectively and fixedly installed on the two collecting water tanks 30, and control valves are respectively arranged in the two sewage discharge pipes. Vertical rods 33 are respectively and rotatably installed in the two collecting water tanks 30, and the two vertical rods 33 are respectively rotatably connected to the two air outlet pipes 32 and the frame-shaped plate 3. Propellers 34 are respectively and fixedly installed on the two vertical rods 33. A plurality of stirring plates are respectively and fixedly installed on the two vertical rods 33. Second belt pulleys 35 are respectively and fixedly installed at the tops of the two vertical rods 33. Synchronous belts 28 are respectively sleeved on the two first belt pulleys 29 and the two second belt pulleys 35.

[0023] In order to improve the service life of the driven gear 22 and the driving gear 21, two pull ropes 37 are slidably installed in the sealing pipe 19. To ensure the sealing performance of the sealing pipe 19, through holes are provided in the sealing pipe 19, and rubber sealing rings are fixedly installed in the through holes. The two pull ropes 37 respectively penetrate through the two rubber sealing rings and are slidably and sealingly connected to the inner walls of the two limit sealing rings. The ends of the two pull ropes 37 away from each other both extend outside the sealing pipe 19 and are respectively fixedly connected to the two vertical plates 25. A circular plate 27 is fixedly installed at the ends of the two pull ropes 37 close to each other. When the suction fan 15 is started, the circular plate 27 will be subjected to a vertically downward suction force. Through the pull ropes 37, the two vertical plates 25 will be subjected to a pulling force towards the sealing pipe 19. Through this pulling force, the two driven gears 22 are always tightly meshed with the driving gear 21, so that the wear of the gears is relatively uniform, and the situation of local excessive wear will not occur, thus improving the service life of the driven gear 22 and the driving gear 21.

[0024] In order to guide the pull ropes 37, and then convert the vertically acting force on the pull ropes 37 into a horizontally acting force, and finally pull the two driving gears 21 to be tightly meshed with the driven gears 22, two guide posts are fixedly installed in the sealing pipe 19, and the two guide posts are respectively slidably connected to the two pull ropes 37.

[0025] The working principle of the virtual soldering detection device for lithium batteries provided by the present invention is as follows: In the initial state, the collection water tank 30 is filled with water, and the bottom end of the air outlet pipe 32 is located below the water level. When in use, first move the two U-shaped placement plates 6 away from each other to make the compression spring 10 in a compressed state. Then place the lithium battery circuit board between the two U-shaped placement plates 6. Release the U-shaped placement plates 6, and under the action of the compression spring 10, the two U-shaped placement plates 6 are pushed closer to clamp and fix the lithium battery circuit board. First, start the suction fan 15 to generate a strong suction force, and suck the debris and dust generated by the soldering on the back of the lithium battery circuit board into the suction fan 15 through the air collection hood 17, the horizontal pipe 16, the vertical pipe 20, the sealing pipe 19, and the connecting pipe 18. Finally, discharge it into the collection water tank 30 through the air outlet pipe 32. After cleaning the back of the lithium battery circuit board, rotate the adjusting rod 5 by 180°, rotate the cleaned back to the upper side, and rotate the uncleaned front to the lower side. At this time, use the ultrasonic flaw detector 4 to detect the virtual soldering at the soldering positions on the back and front of the lithium battery circuit board. The suction fan 15 continues to clean the debris and dust on the front of the lithium battery circuit board to prevent the debris and dust from affecting the detection accuracy of the virtual soldering detection device. When the suction fan 15 is started, the high-pressure gas discharged from the air outlet pipe 32 will push the propeller 34 to rotate. The rotation of the propeller 34 drives the vertical rod 33 to rotate, and the rotation of the vertical rod 33 drives the stirring plate to rotate, so that the water in the collection water tank 30 is always in a flowing state and fully contacts the adsorbed dust, thereby adsorbing the dust more cleanly and comprehensively. At the same time, the rotation of the vertical rod 33 drives the second pulley 35 to rotate. The rotation of the second pulley 35 drives the first pulley 29 to rotate through the synchronous belt 28. The rotation of the first pulley 29 drives the rotating rod 23 and the moving gear 22 to rotate. The rotation of the moving gear 22 drives the driven gear 21 and the vertical pipe 20 to rotate, and finally drives the horizontal pipe 16 to rotate, so that the air collection hood 17 continuously changes its position to approach the peripheral edge part of the lithium battery circuit board, thereby cleaning the debris and dust on the peripheral edge part of the lithium battery circuit board completely. At the same time, when the suction fan 15 is started, the circular plate 27 will receive a vertically downward suction force, and through the pull rope 37, the two vertical plates 25 will receive a pulling force close to the sealing pipe 19. Through this pulling force, the two driven gears 22 are always tightly engaged with the moving gear 21, so that the gear wear is relatively uniform, and there will be no situation of local excessive wear, improving the service life of the driven gear 22 and the moving gear 21.

[0026] Compared with the related technology, the virtual soldering detection device for lithium batteries provided by the present invention has the following beneficial effects: The present invention provides a device for detecting the false soldering of a lithium battery. The lithium battery circuit board is placed between two U-shaped placement plates 6. Under the action of the compression spring 10, the two U-shaped placement plates 6 are pushed to approach each other to clamp and fix the lithium battery circuit board. By generating a strong suction force with the suction fan 15, the debris and dust generated during the soldering on the back of the lithium battery circuit board are discharged into the collection water tank 30 through the air collecting hood 17, the horizontal pipe 16, the vertical pipe 20, the sealing pipe 19, the connecting pipe 18, and the air outlet pipe 32. By rotating the adjusting rod 5 by 180°, the cleaned back surface is rotated to the upper side, and the uncleaned front surface is rotated to the lower side. At this time, the ultrasonic flaw detector 4 is used to detect the false soldering at the soldering positions on the back of the lithium battery circuit board, preventing the debris and dust from affecting the accuracy of the false soldering detection device. When the suction fan 15 is started, the high-pressure gas discharged from the air outlet pipe 32 will push the propeller 34 to rotate, and finally drive the stirring plate to rotate, so that the water in the collection water tank 30 is always in a flowing state and is in full contact with the adsorbed dust, adsorbing the dust more cleanly and comprehensively. At the same time, it drives the horizontal pipe 16 to rotate, so that the air collecting hood 17 continuously changes its position to approach the peripheral edge part of the lithium battery circuit board, cleaning the debris and dust on the peripheral edge part of the lithium battery circuit board completely. At the same time, when the suction fan 15 is started, the circular plate 27 will receive a vertically downward suction force, so that the two slave gears 22 are always tightly engaged with the driving gear 21, making the gear wear relatively uniform and preventing local excessive wear, thereby improving the service life of the slave gear 22 and the driving gear 21.
