Description

Technical Field

[0001] The present invention belongs to the technical field related to battery etching, and more specifically, particularly relates to a battery component etching device based on TopCon and perovskite stacking. Background Art

[0002] With the continuous development of TopCon and perovskite stacked battery technology, the application prospects of laser etching devices in the preparation of battery components are broad. In the future, with the continuous advancement of technology and the further reduction of costs, laser etching devices are expected to become one of the standard equipment in the preparation of stacked battery components; in the preparation process of TopCon and perovskite stacked battery components, laser etching devices are one of the core equipment. It uses a laser beam to accurately scribe and etch the battery components to form independent battery cells and build circuit connections. Laser etching has the advantages of low cost, high precision, small dead zone, and high efficiency. It has become the mainstream etching method. However, battery etching in the existing technology has the following defects:

[0003] 1. In the prior art, the battery module etching device based on TopCon and perovskite stacking usually etches the battery cell by spraying or immersion. During the etching process, on the one hand, the etching forming effect is poor due to uneven coverage, and on the other hand, the etching liquid is easily wasted, thereby increasing the production cost, so it does not meet the existing needs;

[0004] 2. In the prior art, the longer the etching solution in the etching device of the battery component based on the TopCon and perovskite stack is placed, the easier it is for the chemical composition in the etching solution to change, thereby causing the etching solution to deteriorate and precipitate. Therefore, for the etching solution that has already slightly precipitated, its uniformity can be maintained by regular stirring, so as to maintain the etching effect of the etching solution on the battery component;

[0005] 3. In the prior art, in the etching operation of the battery module etching device based on TopCon and perovskite stack, the battery panel is usually fixed on one side, and then the battery panel surface is immersed in the etching solution for stable etching.

[0051] Specific use of the present invention:

[0052] The staff puts the battery panels in the TopCon and perovskite stacked battery assembly into the clamping assembly in the processing box 10, and the two ends of the battery panel enter the interior of the two U-shaped frames 44 respectively. First, the two first rubber plates 45 in the clamping assembly elastically squeeze the two ends of the battery panel respectively, so as to preliminarily clamp the two ends of the battery panel; then the two second rubber plates 46 cooperate with the two third rubber plates 47 to squeeze and clamp the upper and lower sides of the two ends of the battery panel, so as to further adjust the battery panel for clamping and fixing.

[0053] Secondly, the staff rotates the two protective doors 12 to close the processing box 10; then the staff controls the spray assembly to start through the control panel 13, at which time the hydraulic telescopic rod 17 extends to drive the external threaded rod 27 and the water pipe 29 to move downward, and the water pipe 29 moves downward to drive the piston plate 30 to move downward, and the piston plate 30 moves downward to cooperate with the second connecting pipe 35 and the second one-way valve 37 to draw the etching liquid inside the storage cylinder 15 into the upper part of the hydraulic chamber 32; at the same time, the external threaded rod 27 moves downward through the outer side of the external threaded rod 27 to contact the inner thread of the internal threaded tube 26, so that the external threaded rod 27 rotates, and the rotation of the external threaded rod 27 drives the water pipe 29 and the piston plate 30 to rotate, and the rotation of the piston plate 30 drives the second stirring plates 33 to rotate, so as to stir and mix the etching liquid entering the upper part of the hydraulic chamber 32 to avoid slight precipitation of the etching liquid. Then, the hydraulic telescopic rod 17 contracts to drive the external threaded rod 27 and the water pipe 29 to move upward, and the water pipe 29 moves upward to drive the piston plate 30 to move upward in the hydraulic chamber 32, so that the etching liquid in the storage cylinder 15 is sucked into the lower part of the hydraulic chamber 32 through the cooperation of the first connecting pipe 34 and the first one-way valve 36; and the external threaded rod 27 moves upward to cooperate with the outer side of the external threaded rod 27 to contact the inner thread of the internal threaded tube 26, so that the piston plate 30 rotates and drives the first stirring plates 31 to rotate to stir and mix the etching liquid in the lower part of the hydraulic chamber 32, so as to avoid slight precipitation of the etching liquid, thereby maintaining the uniformity of the etching liquid in the hydraulic chamber 32 through stirring, so as to maintain the etching effect of the etching liquid on the battery panel. Among them, the T-shaped rod 28 rotates in the external threaded rod 27, so that the rotation of the external threaded rod 27 will not affect the extension and retraction of the hydraulic telescopic rod 17.

[0054] At the same time, the rotation of the external threaded rod 27 drives the water pipe 29 to rotate, and the rotation of the water pipe 29 drives the connecting pipe 20 and the annular water collecting pipe 21 to rotate through the slider 39 and the slide 41. The rotation of the annular water collecting pipe 21 drives the rotation of the plurality of atomizing nozzles 24, so that the etching liquid sprayed by the plurality of atomizing nozzles 24 can be rotated and dropped onto the battery board, and the etching liquid can be further evenly distributed on the upper end of the battery board, thereby ensuring the uniformity of etching. Then, the slider 39 slides vertically in the slide 41, so that the water pipe 29 rotates and moves up and down, which can always drive the connecting pipe 20 and the annular water collecting pipe 21 to rotate, so that the etching liquid in the hydraulic chamber 32 enters the annular water collecting pipe 21 for rotation and stirring and rotary atomization and spraying, which ensures the uniformity of etching on the one hand, and reduces the waste of etching liquid on the other hand.

[0055] Finally, when the etching process of one end face of the solar panel is completed, the staff controls the clamping assembly to start through the control panel 13, and the two stepper motors 18 are started to drive the two rotating plates 43 to rotate respectively. The two rotating plates 43 rotate and make friction contact with the rubber ring 49 through the annular plate 48, so that the two rotating plates 43 rotate smoothly in the two fixed disks 42 respectively. The smooth rotation of the two rotating plates 43 drives the two U-shaped frames 44 to rotate. The rotation of the two U-shaped frames 44 drives the solar panel to turn over smoothly, so as to continue to control the spraying assembly through the control panel 13 to etch the other end face of the solar panel.

[0056] A battery component etching device based on TopCon and perovskite stacking of the present invention is provided with a spraying component, and the piston plate 30 in the spraying component moves up and down in the hydraulic chamber 32 to cooperate with the first connecting pipe 34 and the second connecting pipe 35 to continuously suck the etching liquid in the storage cylinder 15 into the upper and lower parts of the hydraulic chamber 32, and can squeeze the etching liquid in the upper and lower parts of the hydraulic chamber 32 into the annular water collecting pipe 21, so that the etching liquid can be continuously atomized and sprayed onto the battery plate through a plurality of atomizing nozzles 24, and the etching liquid is gradually covered on the upper end of the battery plate in an atomized state, so that the etching liquid can be evenly distributed on the upper end of the battery plate, reducing the waste of etching liquid and reducing production costs; then the outer threaded rod 27 is moved downward to drive the water pipe 29 and the piston plate 30 to move downward to cooperate with the outer side of the outer threaded rod 27 and the inner threaded pipe 21. 26, so that the piston plate 30 and the first stirring plates 31 rotate and move downward, so that the etching liquid in the lower part of the hydraulic chamber 32 is squeezed through the connecting pipe 20 into the annular water collecting pipe 21, and the etching liquid in the hydraulic chamber 32 is stirred at the same time; finally, the water pipe 29 and the piston plate 30 move upward through the external threaded rod 27 to cooperate with the outer side of the external threaded rod 27 to contact the inner thread of the internal threaded pipe 26, so that the piston plate 30 and the second stirring plates 33 rotate and move upward, so that the etching liquid in the upper part of the hydraulic chamber 32 is squeezed through the water pipe 29 into the annular water collecting pipe 21, and the etching liquid in the hydraulic chamber 32 is stirred to avoid slight precipitation of the etching liquid, thereby maintaining the uniformity of the etching liquid in the hydraulic chamber 32 by stirring, so as to maintain the etching effect of the etching liquid on the battery panel.

[0058] The present invention discloses a battery component etching device based on TopCon and perovskite stacking. The external threaded rod 27 rotates to drive the water pipe 29 to rotate. The rotation of the water pipe 29 drives the connecting pipe 20 and the annular water collecting pipe 21 to rotate through the slider 39 and the slide groove 41.

Then, the slider 39 slides vertically in the slide groove 41, so that the water pipe 29 rotates and moves up and down, which can always drive the connecting pipe 20 and the annular water collecting pipe 21 to rotate, so that the etching liquid in the hydraulic chamber 32 enters the annular water collecting pipe 21 for rotation and stirring and rotation atomization and spraying.
