Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell string manufacturing and welding technology, and in particular to a photovoltaic cell string manufacturing and welding device. Background Technology

[0002] A photovoltaic (PV) cell string is a combination of multiple individual PV cells connected in series to form a unit with higher voltage and a certain current output capability. It plays a key role in PV power generation systems, converting solar energy into direct current (DC) to provide power input for inverters, energy storage devices, or the power grid. Multiple PV cell strings can be further connected in parallel or in series to form larger-scale PV arrays to increase power generation and meet the needs of PV power generation projects of different scales.

[0003] In the field of photovoltaic cell string manufacturing, the emergence of welding equipment has brought about automated welding processes that shorten the production cycle, improve efficiency compared to traditional manual welding, better meet the market's growing demand for photovoltaic energy, and reduce after-sales maintenance costs. Automated welding reduces manual input and labor costs, while efficient production and low defect rates reduce material waste, lower material costs, expand the scope of product applications, and lay a solid foundation for enterprises to expand their markets and enhance their competitiveness.

[0004] The welding equipment used in photovoltaic cell string manufacturing has technical shortcomings. The equipment can only provide a single heating method, making it difficult to achieve dual heating welding. During the welding process, it is impossible to accurately control the welding temperature profile, resulting in uneven melting of the solder, leading to incomplete welds and over-welding. It also cannot apply sufficient pressure to the welded area, making it difficult to ensure a tight fit between the two parts. This greatly affects the welding quality and stability of the cell string. Furthermore, the lack of suitable template fixation in the transmission process causes the cells to shift position on the conveyor belt, making it difficult to accurately control the welding position, resulting in welding deviations, reducing the product qualification rate, causing cell collision damage, increasing production costs, and hindering the improvement of production efficiency and product quality.

[0038] Reference Figure 1 , Figure 4 and Figure 5 Glass blocks 20 are fixedly connected to the top and front sides of the bearing plate 1, which plays a certain role in protection and isolation. Multiple rubber blocks 22 are fixedly connected to the bottom of the pressure plate 12, which plays a buffering role.

[0039] Specifically, glass blocks 20 are fixedly connected to the top and front sides of the support plate 1, providing protection and isolation. This effectively prevents external impurities and dust from entering the device and interfering with the welding process, while not affecting the operator's observation of the internal working conditions, ensuring smooth welding operations. Multiple rubber blocks 22 are fixedly connected to the bottom of the pressure plate 12, acting as a buffer to prevent scratches on the surface of the battery cells or damage to the internal structure due to rigid contact when pressure is applied, thereby improving the yield rate of the welded battery cells. A thermometer 18 is fixedly connected to the front side of the front glass block 20. An luminous pointer 19 is rotatably connected inside the thermometer 18 to detect the temperature near the welding area, allowing the operator to monitor the temperature. The operator can intuitively and promptly grasp the temperature changes of the welding environment, so as to flexibly adjust the welding parameters according to the actual situation and ensure the stability of welding quality. Support plates 21 are fixedly connected between adjacent support columns 206 to improve the support structure strength of the mechanism and enhance the stability of the entire conveying mechanism 2 during operation. This prevents the device from shaking due to unstable support, which would affect the conveying and welding accuracy of the battery string. Multiple sponge strips 23 are set inside the storage box 208, which can play a buffering and protective role, preventing the welded battery strings from colliding with each other or rubbing against the box wall of the storage box 208 during storage and transportation. This effectively reduces the risk of damage to the battery strings and ensures the integrity of the product from production to subsequent storage.

[0040] Working principle: After the battery string reaches the welding position, the multiple telescopic rods 3 on the top of the support plate 1 adjust the height of the base plate 4 according to the preset welding requirements, so that the mounting plate 6 and its internal welding components are aligned with the welding part of the battery string, ensuring the accuracy of welding. The heating wires 9 on the left and right sides of the inner wall of the mounting plate 6 are energized and heat up, creating a basic high-temperature environment in the welding area to soften the solder initially. The power supply 7 on the left and right sides of the bottom of the mounting plate 6 supplies power to the laser 8. The beam emitted by the laser 8 precisely heats the welding part of the battery string, causing the solder to melt quickly and evenly. When the solder reaches the appropriate melting state, the multiple telescopic rods 11 at the bottom of the fixed plate 10 control the lifting and lowering of the pressure plate 12, applying uniform pressure to the battery cell, so that the battery cell and the welding strip are tightly attached. Under the combined action of heating and pressure, the battery cell and the welding strip are firmly connected, completing the welding process.

[0041] When the photovoltaic cell string enters the conveyor mechanism 2, the two connecting plates 201 of the conveyor mechanism 2 connect the support plate 1 and the conveying components to form a stable overall structure. After the motor 202 starts, its output end passes through the front connecting plate 201 and is fixedly connected to the conveyor belt 203 to provide power to the conveyor belt 203. It rotates at a preset speed, smoothly receiving and conveying the cell string to be welded forward. Multiple baffles 204 fixedly connected to the outer wall of the conveyor belt 203 can effectively prevent the cell string from shifting during transportation, ensuring that the cell string always maintains an accurate position on the conveyor belt 203. Multiple rubber pads 205 fixedly connected to the outer wall of each baffle 204 ensure the fixing effect and surface quality of the cell string. The support columns 206 on the front and rear sides of the bottom of the two connecting plates 201 provide stable support for the entire conveyor mechanism 2, ensuring that the cell string is transported to the welding position. After welding is completed, the conveyor belt 203 continues to transport the cell string to the right side. The storage box 208 connected through the connecting frame 207 will collect these welded cell strings, which facilitates the subsequent centralized sorting and handling of the finished products, improving work efficiency.
