Description

Technical Field

[0001] The utility model relates to the technical field of string welding devices, in particular to a photovoltaic cell string welding device. Background Art

[0002] The string soldering process is the process of connecting individually welded solar cells in series, one by one, according to the number required by the process. This process is particularly important in the production of solar panels, as the number and weight of solar cells are large, making temperature control in the constant temperature chamber difficult. If the string soldering process is unqualified, it will lead to uneven temperatures of the solar cells, thus affecting the power generation effect. The implementation of the string soldering process relies on the photovoltaic string soldering machine, which is the core equipment of the photovoltaic module packaging production line. It is used to connect the solar cells in series to obtain high voltage, while ensuring that the cells are tightly connected to achieve efficient photoelectric conversion. The photovoltaic string soldering machine is mainly composed of an automatic feeding system, a solder ribbon processing system, a welding system, and a cell preheating system. With the development of technology, the string soldering process is also constantly upgrading, such as the transition from busbar to busbar-free, which has brought new space and challenges to the development of photovoltaic string soldering machines.

[0003] According to the authorization announcement number CN 212420158 U, a string welding device for photovoltaic cell modules is disclosed, which relates to the technical field of string welding devices. The utility model includes a base, on which a conveying mechanism, a string welding machine and a film laminating device are provided. The conveying mechanism is provided with a conveying roller, and the outer surface of the conveyor belt is fixed with a baffle at intervals. Two limit seats symmetrical with respect to the conveyor belt are fixed on the upper surface of the base. The tops of the two limit seats are rotatably engaged with a driving rod, and two buffer wheels symmetrical with respect to the conveyor belt are fixed on the driving rod. The tops of the limit seats are rotatably engaged with a rotating shaft, and a buffer baffle is fixed to the top of the rotating shaft. The bottom of one end of the buffer baffle is connected to the top of the limit seat by a torsion spring, and the buffer baffle can cooperate with the baffle. The utility model pushes the battery module through the baffle, and adjusts the position of the battery module through the cooperation of the buffer baffle, the baffle and the auxiliary wheel to ensure that the grid lines in the battery module are aligned with the position of the welding strip, thereby ensuring the welding efficiency of the string welding machine.

[0028] The limiting assembly 3 includes several groups of mounting blocks 31 connected to the side of the transmission assembly 2, and a first motor 32 is installed on the side of each group of the mounting blocks 31. A mounting groove 33 is opened inside each group of the mounting blocks 31, and a threaded rod 34 is installed inside each group of the mounting grooves 33. A limiting rod 35 is installed on both sides of the threaded rod 34 inside each group of the mounting grooves 33, and a sliding block 36 is installed inside each group of the mounting grooves 33.

A rotating roller 38 is rotatably installed on the outer arc surface of each group of the fixing rods 37, and a fixing buckle 39 is installed on the top of each group of the fixing rods 37.

[0029] In this embodiment, if Figure 1 As shown, the transmission component 2 includes several groups of support plates 201 connected to the base 1, two groups of conveying platforms 202 are installed on the upper part of the several groups of support plates 201, and several groups of connecting rods 203 are installed in the middle part of the two groups of conveying platforms 202. The support plates 201 are used to support the conveying platforms 202, and the connecting rods 203 are used to connect the two groups of conveying platforms 202 together, so that the anti-deflection conveyor belt 205 on the conveying platform 202 can transmit the photovoltaic cell components, thereby improving the practicality of the entire device.

[0030] In a further preferred embodiment, Figure 2 As shown, rotating wheels 204 are rotatably installed at both ends of each group of the conveying platforms 202, and anti-deflection conveyor belts 205 are installed on the outside of every two groups of rotating wheels 204. The rotating wheels 204 at both ends of the conveying platforms 202 are used to rotate the anti-deflection conveyor belts 205. Through the cooperation of the rotating wheels 204 and the anti-deflection conveyor belts 205, the photovoltaic cell components are facilitated to be transported, thereby improving the practicality of the entire device.

[0031] Further, such as Figure 3 As shown, a second motor 206 is installed at the bottom of a group of the conveying platforms 202, and the output end of the second motor 206 passes through the support plate 201 and is key-connected to a first rotating shaft 207. The second motor 206 at the bottom of the conveying platform is started, and the second motor 206 drives the first rotating shaft 207 to rotate, and drives the first gear 209 inside the placement box 208 to rotate, thereby driving the second gear 210 to rotate, so that the second rotating shaft 211 rotates on the bearing 212, and drives the rotating wheel 204 to rotate, so that the anti-deflection conveyor belt 205 can rotate normally to transport the photovoltaic cell components. Through the cooperation of the above components, the practicality of the entire device is improved.

[0032] Preferably, Figure 3As shown, a placement box 208 is installed on the side of a group of the conveying platforms 202, and the end of the first rotating shaft 207 passes through the placement box 208 and is installed with a first gear 209. The placement box 208 on the side of the transport platform 202 is used to place the first gear 209 and the second gear 210 to protect the safety of the first gear 209 and the second gear 210.

The first gear 209 is engaged with the second gear 210 to start the second motor 206. The first rotating shaft 207 will drive the first gear 208 to rotate. Since the first gear 209 is engaged with the second gear 210, the first gear 209 will drive the second gear 210 to rotate, which is convenient for subsequent transportation components to transport the photovoltaic cell components and improve the practicality of the device.

The second rotating shaft 211 installed in the middle of the second gear 210 passes through the rotating wheel 204 and the conveying platform 202. When the second gear 210 rotates, the second rotating shaft 211 will drive the rotating wheel 204 to rotate, so that the anti-deflection conveyor belt 205 rotates accordingly, and the anti-deflection conveyor belt 205 drives the photovoltaic cell assembly to be transferred to the rear-end string welding machine for string welding.

[0035] Further, such as Figure 5 As shown, a gantry 4 is installed on the upper part of the base 1, and a circular groove 5 is provided on the upper surface of the gantry 4.

[0036] In addition, if Figure 5 As shown, a hydraulic press 6 is installed inside the circular groove 5, and a hydraulic rod 7 is installed at the output end of the hydraulic press 6. A hydraulic rod 7 is installed at the bottom of the hydraulic press 6 inside the circular groove. The hydraulic rod 7 is used to connect the bottom stringer 9. Through the cooperation of the hydraulic press 6 and the hydraulic rod 7, the stringer 9 can move up and down on the anti-deviation conveyor belt 205 for welding, thereby improving the practicality of the device.

[0037] It is worth noting that if Figure 5As shown, a connecting plate 8 is installed at the bottom of the hydraulic rod 7, and a stringer 9 is installed at the bottom of the connecting plate 8.
