[0002] With the surge in demand for clean energy and the performance bottleneck of traditional crystalline silicon solar cells, the photovoltaic industry needs new technology breakthroughs. Heterojunction assemblies have emerged as the times require. It uses n-type or p-type silicon wafers as substrates, constructs p-n heterojunctions by depositing intrinsic and doped amorphous silicon films, and effectively improves solar energy utilization efficiency with a theoretical conversion efficiency of up to 29.2%, excellent temperature coefficient, and high stability. At the same time, its low-temperature preparation process avoids thermal stress problems and ensures long-term power generation performance, meeting the market demand for efficient and stable photovoltaic products and becoming a key technology roadmap for promoting the photovoltaic industry to a new stage of high efficiency and low carbon. In the process of heterojunction assembly automation, wafers or assemblies are prone to explosion during transmission, handling, and processing due to their thinness and brittleness.

[0003] Existing automated equipment mostly uses single suction cup adsorption or simple mechanical clamping, which can easily lead to uneven stress on the assembly, combined with factors such as inertial impact during high-speed transmission and equipment vibration, resulting in a high explosion rate. Explosion not only causes waste of raw materials and increases production costs, but also seriously affects production efficiency and reduces product yield due to frequent downtime to handle faults. SUMMARY

[0004] To solve the above technical problems, the utility model provides an improved mechanism for reducing the explosion of heterojunction assembly in automation.

[0006] Through the above technical scheme, the suction cup grasps the heterojunction assembly through the vacuum adsorption principle, has a large contact area and uniform force, and can greatly reduce the risk of explosion caused by local stress concentration compared to mechanical clamping. The suction cup platform is installed at the front and rear ends of the lifting frame, which can assist in fixing the edges or non-sensitive areas of the assembly and enhance the stability during grasping to prevent the assembly from twisting or tilting during lifting.

[0007] As a further improvement of the above scheme, the inside of the support frame and the two sides of the lifting frame are slidably connected.

[0008] As a further improvement of the above-mentioned scheme, the number of the suction cups is set to several, and the several suction cups are located on both sides of the top of the lifting frame.

[0009] As a further improvement of the above-mentioned scheme, the suction cup platform is located at the front and rear ends of the top of the lifting frame.

[0010] As a further improvement of the above-mentioned scheme, the transmission device comprises a first support, and U-shaped supports are fixedly connected to the left and right sides of the first support, a supporting roller is rotatably connected to one side of the U-shaped support, and a transmission belt is rotatably connected to the surface of the U-shaped support.

[0011] As a further improvement of the above-mentioned scheme, the first support is located at the top of the lifting frame, and the bottom of the first support is fixedly connected to the top of the lifting frame.

[0012] As a further improvement of the above-mentioned scheme, the number of the supporting rollers is set to four, and the number of the transmission belts is set to two.

[0013] Through the above technical scheme, the supporting rollers directly support the heterojunction assembly, the supporting surface formed by the four supporting rollers can uniformly disperse the weight of the assembly, and local stress concentration caused by single-point support is avoided. The surface of the supporting roller is usually designed as a smooth curved surface or a flexible material, which can buffer vibration and impact when contacting the assembly, and allows the assembly to smoothly slide along the belt, reducing friction damage.
