[0037] See also Figure 1-Figure 10 As shown, a transport clamping device for the production of PERC bifacial cells is provided, comprising a housing 110 and a servo motor 111, wherein the servo motor 111 is mounted on one side of the housing 110; the housing 110 has a receiving space, and an openable and closable door panel is provided at at least one side opening of the housing 110, and a clamping assembly 20 is rotatably provided in the receiving space, wherein the clamping assembly 20 is provided with a plurality of clamping grooves;

[0040] During specific use, during the pre-storage process of stacking the PERC double-sided batteries, the servo motor 111 rotates forward to drive the entire clamping assembly 20 from a vertical state to a parallel state. During this process, the servo motor 111 drives the two second horizontal conveying assemblies 114 to transmit forwardly through one side of the vertical conveying assembly 112. The two second horizontal conveying assemblies 114 respectively drive the lower opening and closing plate 130 and the upper opening and closing plate 140 that are connected to each other through transmission. The lower opening and closing plate 130 and the upper opening and closing plate 140 move away from each other to form a gap. At the same time, the servo motor 111 drives the transmission gear to rotate through the other side of the vertical conveying assembly 112. The transmission gear drives the two first horizontal conveying assemblies 113 to transmit in the opposite direction. The two first horizontal conveying assemblies 113 respectively drive the lower opening and closing plate 130 and the upper opening and closing plate 140 that are connected to each other through transmission. The lower opening and closing plate 130 and the upper opening and closing plate 140 move away from each other to form a gap, so that both sides of the shell 110 are in an open state. state, at this time, the clamping assembly 20 rotates from the vertical state to the parallel state, and each PERC bifacial battery is inserted into the inner end of the corresponding clamping groove 221, and the two sides of the PERC bifacial battery are clamped by the two inner plates 222. After the clamping work is completed, the servo motor 111 reverses to drive the entire clamping assembly 20 to rotate from the parallel state to the vertical state, and the lower opening and closing plates 130 and the upper opening and closing plates 140 on both sides are close to each other to form a closed surface to fill the gap. During the transportation of the vehicle, the pressure will be output along the side of the PERC bifacial battery, thereby reducing the impact of the shaking of the vehicle during transportation on the PERC bifacial battery. At the same time, the servo motor 111 rotates forward to drive the entire clamping assembly 20 to rotate from the vertical state to the parallel state. At this time, the lower opening and closing plates 130 and the upper opening and closing plates 140 on both sides are far away from each other to form a gap. The operator can stack or disassemble the PERC bifacial battery from the gap to improve the stacking and disassembly efficiency.

[0041] In addition, the vertical transmission component 112 includes three vertical gears, the vertical gear located in the middle position is coaxially connected to the servo motor 111, and the other two vertical gear sides are coaxially connected with concentric gears, and vertical belts are meshed and connected between each vertical gear, and one side of the concentric gears is respectively meshed with the two steering gears. The first horizontal transmission component 113 includes a pair of first horizontal gears, and a first horizontal belt is meshed and connected between the two first horizontal gears, and the two first horizontal gears on one side are coaxially connected with the two steering gears, and the two first horizontal gears on the other side are respectively rotatably connected with the lower opening and closing plate 130 and the upper opening and closing plate 140 on the same side. The second horizontal transmission component 114 includes a pair of second horizontal gears, and a second horizontal belt is meshed and connected between the two second horizontal gears, and the two second horizontal gears on one side are respectively coaxially connected with the two vertical gears, and the two second horizontal gears on the other side are respectively rotatably connected with the lower opening and closing plate 130 and the upper opening and closing plate 140 on the same side. During specific use, the servo motor 111 drives the vertical gear located in the middle position to rotate, and the vertical gear located in the middle position drives the other vertical gears on both sides to rotate through the vertical belt, and the vertical gears on both sides respectively drive the two steering gears to rotate, and the steering gear drives one of the first transverse gears, and one of the first transverse gears drives the first transverse gear on the other side to rotate through the first transverse belt, and the rotation of the two first transverse gears respectively drives the lower opening and closing plate 130 and the upper opening and closing plate 140 on the same side to rotate, so that an opening or closure is formed between the lower opening and closing plate 130 and the upper opening and closing plate 140 on the same side, and at the same time, the servo motor 111 will drive the clamping assembly 20 to rotate during the rotation process, and drive the vertical gear at the middle position of the other side to rotate through the clamping assembly 20, and the vertical gear drives one of the second transverse gears to rotate, and one of the second transverse gears drives the second transverse gear on the other side to rotate through the second transverse belt, thereby driving the lower opening and closing plate 130 and the upper opening and closing plate 140 on the same side to rotate, so that an opening or closure is formed between the rotation of the lower opening and closing plate 130 and the upper opening and closing plate 140, so that the two sides of the housing 110 are synchronously opened or closed.

[0042] During the transportation of the PERC bifacial battery, the inner end of the shell 110 is sealed, and the air inside and outside cannot circulate. The inner end of the shell 110 is closed for a long time, and the heat generated cannot be discharged, causing the temperature of the inner end to continue to rise, which will affect the PERC bifacial battery. Furthermore, a plurality of ventilation grooves are provided on the side of the lower opening and closing plate 130 and the side of the upper opening and closing plate 140, and the ventilation grooves are evenly distributed. The ventilation grooves are provided to realize air circulation inside and outside the shell 110, so that the heat at the inner end of the shell 110 can be discharged in time, ensuring that the PERC bifacial battery is at a normal temperature.

[0043] The cam 140 is provided with a plurality of latches 131 which are provided at the top edge of the bottom edge of the bottom opening and closing plate 130, and a plurality of latches 141 which are provided at the bottom edge of the bottom opening and closing plate 130 are provided. The latches 141 are engaged with the latches 131, and the connection stability between the lower opening and closing plate 130 and the upper opening and closing plate 140 is improved by the provided latches 131 and the latches 141. When the lower end of the upper opening and closing plate 140 contacts the top end of the lower opening and closing plate 130, each latches 141 is respectively engaged with the inner end of the corresponding latches 131, and an interaction force is generated between the two, thereby improving the connection stability between the upper opening and closing plate 140 and the lower opening and closing plate 130.

[0044] Specifically, a plurality of grooves 2221 are formed on the sides of the two inner plates 222, and the grooves 2221 are evenly distributed on the sides of the inner plates 222. When the clamping assembly 20 is rotated to a vertical state, each perc bifacial battery and the contact surfaces of the two inner plates 222 are connected only by friction, and the clamping is easily loosened, causing the perc bifacial battery to slide off the contact surfaces of the two inner plates 222. At this time, the grooves 2221 are provided to increase the roughness of the sides of the inner plates 222, and to increase the friction generated by the contact surfaces of the inner plates 222 and the perc bifacial battery, thereby improving the clamping stability of the perc bifacial battery and preventing the perc bifacial battery from sliding off.

[0045] As the PERC bifacial battery slides into the clamping groove 221, it will first contact the edge positions at both ends of the inner plate 222, and the gap between the two inner plates 222 is consistent with the thickness of the PERC bifacial battery. During the actual sliding process, the edge positions of the PERC bifacial battery can easily touch the edge positions at both ends of the inner plate 222. The edge positions at both ends of the inner plate 222 will hinder the PERC bifacial battery from continuing to slide, which can easily cause the PERC bifacial battery to bend. In addition, the edge positions at both ends of the inner plate 222 are both arranged to be arc-shaped. The edge positions at both ends of the inner plate 222 are designed to be arc-shaped, so that the openings at the edge positions at both ends of the inner plate 222 are increased, ensuring that the PERC bifacial battery can smoothly slide between the two inner plates 222 to complete the normal clamping work.

[0046] Furthermore, a plurality of plugs 223 are connected between the inner plate 222 and the inner side of the clamping plate 220. The plugs 223 are plugged into the inner side of the clamping plate 220, and the ends of the plugs 223 are connected to the limit springs 224. When in use, the clamping force of the inner plate 222 on the perc bifacial battery is increased by the provided plugs 223 and the limit springs 224. After the perc bifacial battery slides between the two inner plates 222, it will squeeze the two inner plates 222. The inner plates 222 push the plugs 223 to insert into the inner side of the clamping plate 220. At the same time, the plugs 223 squeeze the limit springs 224, so that the limit springs 224 are in a compressed state. The reverse force provided by the compression of the limit springs 224 drives the inner plate 222 to fit on the side of the perc bifacial battery, and further clamps and fixes the perc bifacial battery.

[0047] Furthermore, a pair of rollers 225 are provided at both ends of the clamping groove 221, and a gap is reserved between the two rollers 225. In specific use, when the PERC bifacial battery enters the clamping groove 221, it will first pass through the reserved gap between the two rollers 225, and at the same time drive the two rollers 225 to rotate, and the rollers 225 roll to guide the PERC bifacial battery to quickly slide into the inner end of the clamping groove 221, thereby improving the stacking efficiency and reducing the occurrence of jamming.

[0048] In addition, the cross-sectional dimensions of the roller 225 are consistent with the cross-sectional dimensions of the clamping groove 221. When in use, the cross-sectional dimensions of the roller 225 are designed to be consistent with the cross-sectional dimensions of the clamping groove 221, so that when the perc bifacial battery is inserted into the clamping groove 221, the sliding angle is consistent and the position is always consistent, preventing the perc bifacial battery from being offset when sliding, and easily rubbing against the inner wall of the clamping groove 221, resulting in the loss of the edge position of the perc bifacial battery, affecting the use quality of the perc bifacial battery.
