Description

Technical Field

[0001] The utility model relates to the field of battery transportation, in particular to a transportation clamping device for TOPCon battery production. Background Art

[0002] TOPCon cells are tunneling oxide passivation contact cells. They mainly use N-type silicon wafers as carriers. Based on PERC cells, an extremely thin silicon oxide layer (1~2nm) is prepared on the back, namely the tunneling oxide layer. Then a layer of phosphorus-doped microcrystalline amorphous mixed silicon film is deposited. The crystallinity of the mixed silicon film changes during the annealing process and turns into polycrystalline to form a passivation contact structure. The ultra-thin silicon oxide layer of the TOPCon cell uses the quantum tunneling effect to allow majority carriers to tunnel while blocking minority carriers from passing through. A layer of metal is deposited on it as an electrode to achieve a passivation contact structure without opening holes. Current transmission can be completed without contacting the silicon wafer, thereby reducing the efficiency loss caused by recombination at the battery electrodes. Therefore, TOPCon cells are gradually replacing traditional batteries.

[0003] Due to the high value and fragility of TOPCon batteries, safely and efficiently transporting and carrying TOPCon batteries has become an important and challenging issue. At present, there are some demands for the transportation of TOPCon batteries in the market, such as the use of foam materials for packaging. This transportation device is not very good for the safety and fixation of the batteries. Batteries are prone to collision, resulting in damage to product quality. In addition, when placing and removing batteries, the operation is relatively complicated and the work efficiency is low. In general, the development of an efficient TOPCon battery transportation clamping device is of great significance to ensure the safe and effective transportation of batteries, which will help promote the widespread application of TOPCon batteries in various fields and achieve sustainable development and green travel. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0019] The following describes an embodiment of the utility model based on its overall structure.

[0020] The utility model provides a transport clamping device for TOPCon battery production, such as Figure 1-2 As shown, it includes a main body 1, both ends of the inner wall of the main body 1 are rotatably connected with a rotating column 15, and the end of the rotating column 15 is rotatably connected with a placement plate 5, and a rotating column 16 is arranged on one side of the placement plate 5, and the inner wall of one side of the main body 1 is provided with a first slide groove 10, a second slide groove 11, a third slide groove 12, and a fourth slide groove 13, and the first slide groove 10, the second slide groove 11, the third slide groove 12, and the fourth slide groove 13 cooperate with the sliding column 16, and the first slide groove 10, the second slide groove 11, the third slide groove 12, and the fourth slide groove 13 are arranged, so that the four groups of placement plates 5 located at the top can be rotated upward.

[0021] It should be pointed out that there are five groups of placement plates 5. The four groups of placement plates 5 at the top correspond to the first slide groove 10, the second slide groove 11, the third slide groove 12, and the fourth slide groove 13 respectively. The placement plates 5 at the bottom are fixed to the inside of the main body 1. When placing the TOPCon battery, the placement plate 5 at the top is first rotated away from the inside of the main body 1, and the TOPCon battery is placed on the top of the placement plate 5 at one time, so that the battery is convenient to place and take out, thereby improving the transportation efficiency.

[0022] See also Figure 3 A cavity 7 is provided inside the placement plate 5, and a stud 8 is rotatably connected inside the cavity 7. A slider 9 is slidably connected inside the cavity 7, and a clamping plate 6 is fixed on the top of the slider 9. The outer side of the stud 8 is evenly provided with mutually symmetrical opposite threads.

[0023] It can be understood that the multiple groups of symmetrical opposite threads arranged on the outside of the stud 8 correspond to a group of clamps 6. The TOPCon battery is placed inside the clamps 6. When the stud 8 rotates, under the action of the opposite threads, each group of clamps 6 moves relative to each other to clamp the TOPCon battery, thereby achieving the purpose of fixing.

[0024] See also Figure 1 and 4 , one side of the main body 1 is evenly provided with sockets 2, and the inside of the sockets 2 is plugged with handles 3, which is convenient for pulling out the handles 3 and inserting them into another set of sockets 2. A limiting hole 14 is provided on one side of the stud 8, and the limiting hole 14 cooperates with the handle 3, and the cross-section of the end of the handle 3 and the cross-section of the limiting hole 14 are both rectangular.

[0025] It should be noted that multiple groups of slots 2 correspond to multiple groups of placement plates 5. The handle 3 is inserted into the slot 2. The cross-section of the end of the handle 3 is rectangular, which can drive the stud 8 to rotate. The rotation of the stud 8 is convenient to drive the clamping plate 6 to clamp the TOPCon battery, which has a good fixing effect on the battery, improves the safety of the battery during transportation, and reduces the risk of battery damage during transportation.

[0026] See also Figure 1 A forklift hole 4 is provided at the bottom end of one side of the main body 1 to facilitate the forklift to move the main body 1, and the height of both sides of the main body 1 is higher than the height of the TOPCon battery at the top, which facilitates the stacking of the main body 1.
