DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] The battery clamping device in the prior art has poor stability in clamping the battery, and cannot clamp and limit two TOPCon batteries of different sizes at the same time, has poor adaptability, and is inconvenient to pick up. In order to solve this technical defect in the prior art, such as Figure 1 , Figure 2as well as Figure 3 As shown, this embodiment proposes a TOPCon battery clamping device, which can fix TOPCon batteries of different sizes in multiple directions at one time, greatly improving the stability of the TOPCon battery during transportation. The interior of the rectangular box 1 of the device is provided with a battery clamping mechanism 2 and a layered anti-pressure mechanism 3 for limiting the battery, and the rectangular box 1 is provided with a safety protection mechanism 4 to prevent the battery from being damaged. During the transportation of the battery, the battery clamping mechanism 2 and the layered anti-pressure mechanism 3 will clamp and limit the TOPCon battery, which can effectively prevent the battery from being damaged during transportation.

[0031] Specifically, the battery clamping mechanism 2 includes a limiting base 201 movably mounted inside the rectangular box 1, two horizontal slide grooves 202 are symmetrically provided on the limiting base 201, an L-shaped bracket 203 is movably installed on the horizontal slide groove 202, a fixed platform 204 is arranged in the middle of the limiting base 201, a driving square box 205 is arranged on the fixed platform 204, a bidirectional screw 206 is movably installed on the driving square box 205, and both ends of the bidirectional screw 206 are respectively threadedly matched with the two L-shaped brackets 203. When the bidirectional screw 206 rotates, the two symmetrical L-shaped brackets 203 are moved closer to or away from each other, a plurality of limiting vertical rods 207 are evenly spaced on the L-shaped bracket 203, and a battery limiting groove 208 is provided on the limiting base 201 The number of battery limiting grooves 208 matches the number of limiting vertical rods 207. The lower end of the limiting vertical rod 207 extends to the inside of the battery limiting groove 208. When the L-shaped bracket 203 moves horizontally, the limiting vertical rod 207 will move synchronously along the battery limiting groove 208. The limiting vertical rod 207 is detachably mounted with a sponge gasket 209, which can effectively reduce the damage to the battery during the clamping process. The middle coaxial sleeve of the bidirectional screw 206 is provided with a driven gear 210, and the interior of the driving square box 205 is provided with a driving assembly 211 for driving the bidirectional screw 206 to rotate. When the staff stacks the battery between the two L-shaped brackets 203, the two L-shaped brackets 203 will approach each other under the action of the bidirectional screw 206, thereby clamping and limiting the battery.

[0032] According to the above content, if Figure 1 As shown, when placing the battery, the staff will pull the limiting base 201 to the upper end of the rectangular box 1, and then stack the block-shaped TOPCon batteries of the same size between the two L-shaped brackets 203.

[0033] Next, the bidirectional screw 206 will rotate under the action of the driving assembly 211 (composed of a driving gear and a driving motor, and the driving gear is meshed with the driven gear 210). When the bidirectional screw 206 rotates, the two L-shaped brackets 203 on the same side will approach each other. When the L-shaped brackets 203 approach each other, the limiting vertical rod 207 will contact the battery, thereby clamping and limiting the two sides of the battery.

[0034] Subsequently, the staff will place a block-shaped TOPCon battery of another size between the two L-shaped brackets 203 on the other side. Next, the two L-shaped brackets 203 will approach each other in the same way to clamp and limit the battery.

[0035] This embodiment provides a battery clamping mechanism 2, and utilizes the mutual cooperation between the L-shaped bracket 203 and the limiting vertical rod 207, so that TOPCon batteries of different sizes can be fixed in multiple directions at one time, which greatly improves the stability of the TOPCon batteries during transportation and can effectively prevent the TOPCon batteries from being damaged during transportation; moreover, this embodiment provides a battery clamping mechanism 2, and utilizes the mutual cooperation between the L-shaped bracket 203 and the bidirectional screw 206, which can not only effectively improve the clamping efficiency, but also quickly release the clamping during the process of taking the battery, so that the staff can take it easily.

[0036] Embodiment 2

[0037] In order to prevent the TOPCon battery at the bottom from being crushed during stacking, based on the first embodiment, Figure 1 and Figure 6 As shown, the present embodiment is provided with a layered anti-pressure mechanism 3. Specifically, the layered anti-pressure mechanism 3 includes mounting protrusions 301 symmetrically mounted on the fixed platform 204. A rotating circular shaft 302 is rotatably mounted between the two mounting protrusions 301. A layered support plate 303 is fixedly mounted on the rotating circular shaft 302. A small motor 304 for driving the rotating circular shaft 302 is fixedly mounted on the mounting protrusion 301. Initially, the layered support plate 303 is in a vertical state. When the TOPCon batteries are stacked, the layered support plate 303 will rotate to a horizontal state under the action of the small motor 304. The small motor 304 is a brake motor. There is an electromagnetic brake at the tail of the motor. When the motor is powered on, it is also powered on and attracted. At this time, it does not brake the motor. When the motor is powered off, it is also powered off. The brake brakes the motor under the action of the spring.

[0038] According to the above content, when a large number of TOPCon batteries need to be stacked, the layered support plate 303 will rotate to a horizontal state under the action of the small motor 304. Next, when the bottom of the layered support plate 303 is full of batteries, the staff will put the remaining batteries on the top of the layered support plate 303. At this time, there is still a certain gap between the layered support plate 303 and the batteries below, thereby preventing the bottom TOPCon from being crushed.

[0039] This embodiment provides a layered anti-pressure mechanism 3, and utilizes the cooperation between the layered support plate 303 and the small motor 304 to arrange the block-shaped TOPCon batteries in layers, thereby preventing the upper batteries from exerting heavy pressure on the bottom batteries, and effectively preventing the bottom batteries from being crushed.

[0040] Embodiment 3

[0041] In order to prevent the TOPCon battery from bumping into other objects or getting damp during transportation, based on the above embodiment, Figure 1 and Figure 4 As shown, the present embodiment is provided with a safety protection mechanism 4. Specifically, the safety protection mechanism 4 includes fixed convex strips 401 symmetrically arranged on both sides of the rectangular box body 1. Two sliding cover plates 402 are movably installed on the rectangular box body 1. The sliding cover plates 402 are provided with linear slide rails 403 matching the fixed convex strips 401. A supporting handle 404 for supporting the limiting base 201 is movably installed on the side of the rectangular box body 1. After the battery is placed, the staff will put the limiting base 201 into the interior of the rectangular box body 1, and then move the sliding cover plate 402 to the top of the rectangular box body 1. A side wall cavity 405 is opened on the inner wall of the rectangular box body 1, and a solid desiccant 406 is placed inside the side wall cavity 405, so as to ensure that the interior of the rectangular box body 1 is in a dry state and prevent the battery from getting damp.

[0042] According to the above content, during the placement of the battery, the two support handles 404 will support the lower end of the limiting base 201. After the battery is placed, the staff will pull the support handles 404 outward to place the limiting base 201 inside the rectangular box 1.

[0043] After placement is completed, the staff will push the sliding cover 402 to the top of the rectangular box 1, thereby closing the upper end of the rectangular box 1 to prevent the battery from colliding with other items during transportation.

[0044] In addition, the solid desiccant 406 absorbs the water vapor inside the rectangular box 1, thereby ensuring that the interior of the rectangular box 1 is in a dry state, which can effectively prevent the battery from getting damp.

[0045] By providing a safety protection mechanism 4 and utilizing the cooperation between the sliding cover 402 and the rectangular box 1, this embodiment can provide better protection for the TOPCon battery during transportation, effectively prevent the battery from contacting other objects or dust, and greatly improve the safety of transportation; moreover, by providing a safety protection mechanism 4 and utilizing the cooperation between the side wall cavity 405 and the solid desiccant 406, this embodiment can always ensure that the interior of the rectangular box 1 is in a dry state during transportation, thereby preventing the battery from getting damp.

[0046] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
