The sealing ring 21 completely covers the upper end of the air nozzle 15. The opening and closing assembly regulates the air to pass through the vertical pipe 14 into the connecting pipe 17.

[0034] The opening and closing assembly includes a baffle 22, a vent 23 and a reset structure.

[0036] The cleaning assembly includes a support frame 32, a brush 33 and an inclined plate 34. The support frame 32 is rotatably mounted on the outside of the vertical pipe 14, and the inclined plate 34 is fixedly mounted on the support frame 32. The inclined plate 34 cooperates with the air outlet 18, and the brush 33 is fixedly mounted on the outside of the support frame 32. The brush 33 is horizontally arranged.

[0037] A mold groove 51 is provided at the center of the upper portion of the mold plate 12 , and a ball bearing 52 is rotatably mounted on the upper portion of the mold plate 12 .

[0038] The process flow of the device proposed in this embodiment is as follows:

[0039] The battery to be processed is placed on the mold plate 12 by a robotic arm or a feeding device. When it needs to be explained, the mold groove 51 on the mold plate 12 corresponds to the shape of the battery. The air pump 31 is connected to an external power supply. The air pump 31 transports external air to the interior of the vertical pipe 14 and sprays it out through the air nozzle 15, so that the surface of the battery can be cleaned. The mobile trolley 62 drives the vertical pipe 14 to move along the guide rail 61. When the mobile trolley 62 passes through the descending section of the guide rail 61, the mobile trolley 62 drives the vertical pipe 14 to move downward, so that the suction cup 16 can contact the upper end face of the battery.

[0040] When the suction cup 16 contacts the upper end of the battery, the battery squeezes the air nozzle 15, and the air nozzle 15 moves toward the inside of the vertical tube 14. The air nozzle 15 contacts the baffle 22 and drives the baffle 22 to move synchronously. At this time, the spring 24 is squeezed and deformed. When the air nozzle 15 moves to the position of the sealing ring 21, the sealing ring 21 blocks the air nozzle 15, so that the air inside the vertical tube 14 cannot be ejected through the air nozzle 15. At the same time, the vent 23 moves to the position of the connecting tube 17. The air inside the vertical tube 14 can enter the connecting tube 17 through the vent 23 and be discharged through the air outlet 18. While the suction cup 16 adsorbs the battery surface, it can still clean the dust on the battery surface.

[0041] At the same time, when the air is ejected from the air outlet 18, it contacts the inclined plate 34. Under the action of the support frame 32, the air can drive the support frame 32 to rotate around the vertical pipe 14 through the inclined plate 34, thereby driving the brush 33 to rotate. The brush 33 can clean the dust on the surface of the battery.

[0042] When the moving trolley 62 drives the suction cup 16 to move downward, it can also drive the support plate 13 to move downward. The support plate 13 drives the connecting rod 41 to insert into the groove 42, so that the support plate 13 can be connected to the mold plate 12. When the moving trolley 62 drives the support plate 13 to move horizontally through the vertical tube 14, the support plate 13 can drive the mold plate 12 to move synchronously. When the moving trolley 62 moves to the horizontal section of the guide rail 61, the gear 71 engages with the rack 72, thereby driving the vertical tube 14 to rotate. Under the action of the suction cup 16, the vertical tube 14 drives the battery to rotate. The ball 52 can reduce the friction between the battery and the mold plate 12, and at the same time reduce the wear on the battery surface. When the battery rotates to the appropriate position, it can fall into the inside of the mold groove 51. At this time, the suction cup 16 no longer drives the battery to rotate. It should be noted that the weight of the battery is greater than the suction force between the suction cup 16 and the battery. At this time, the suction cup 16 is separated from the battery.

[0043] When the moving trolley 62 moves to the rising section of the guide rail 61, the moving trolley 62 drives the suction cup 16 away from the battery. At the same time, the mold plate 12 is separated from the support plate 13, and the mold plate 12 drives the battery into the interior of the transfer assembly 11, and the transfer assembly 11 processes the battery.

[0044] Through the above-mentioned actions, the present invention can clean the surface of the battery and correct the position of the battery, which is convenient for correcting batteries of different shapes. It only needs to replace the corresponding mold, making the application range of the device wider, and can improve the efficiency of battery transfer, further improve the efficiency of battery preparation, and reduce the workload of staff.

[0045] The second embodiment of the present invention is:

[0046] The present invention discloses a laser transfer process for preparing TOPCON batteries, comprising the following steps:

[0047] The mold is placed on the mold plate 12;

[0048] The moving assembly drives the suction cup 16 to move horizontally above the mold and then downward. During this process, the air pump 31 sprays air through the nozzle 15 through the vertical pipe 14, spraying gas onto the surface of the battery.

[0049] After the suction cup 16 is attached to the upper end surface of the battery, the moving assembly drives the vertical tube 14 to rotate, and the vertical tube 14 drives the battery to rotate on the mold plate 12 to adjust the battery angle;

[0050] When the battery is adjusted to the same angle as the mold groove 51, the gravity of the battery is greater than the suction force between the suction cup 16 and the battery, and the battery falls into the mold groove 51, and the suction cup 16 separates from the battery;

[0051] The mold plate 12 drives the battery to move into the transfer assembly 11 , and the transfer assembly 11 performs transfer processing on the battery.

[0052] The above describes the embodiments of this embodiment, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
