Description

Technical Field

[0001] This utility model relates to the technical field of welding platform structure, specifically a welding platform structure for a solar string welding machine. Background Technology

[0002] Currently, when welding silicon wafers for solar power generation panels, the wafers need to be adsorbed onto the base for stable welding. The industry generally uses a negative pressure method for adsorption, which requires the base to have air intake channels. In order to increase the negative pressure area and evenly distribute the pressure, grooves with larger areas are opened at the openings of the negative pressure vents. Previously, the industry used short vertical grooves perpendicular to the length of the base plate, which easily caused the solder ribbon to fall into the area of ​​the vertical groove. After heat welding, uneven pressure resulted in poor welding, affecting the stability of the process. Utility Model Content

[0003] The purpose of this invention is to provide a welding platform structure for a solar string welding machine, which solves the problem that uneven heating during welding can easily affect welding stability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a solar string welding machine welding platform structure, including a platform base, a breathable mesh cloth is provided at the upper end of the platform base, a silicon wafer assembly is installed at the upper end of the breathable mesh cloth, a welding strip is provided at the upper part of the silicon wafer assembly, a transverse breathable groove is provided at the upper end of the platform base, and a longitudinal breathable groove is provided at the upper end of the platform base.

[0005] Preferably, there are multiple transverse ventilation slots, which are evenly distributed on the platform base. Multiple transverse ventilation slots can improve air permeability.

[0006] Preferably, there are multiple longitudinal ventilation grooves, which are evenly distributed on the platform base. Multiple longitudinal ventilation grooves can improve air permeability.

[0007] Preferably, the breathable mesh fabric includes a metal mesh and an anti-stick coating, wherein the upper end of the metal mesh is provided with an anti-stick coating, which can prevent materials from sticking together.

[0008] Preferably, the metal mesh is made of a metal material, which may be an aluminum alloy or a copper alloy.

[0009] Preferably, the non-stick coating is made of Teflon, a material with good non-stick properties.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model adds a transverse ventilation groove and a ventilation mesh to the platform base. During use, the ventilation mesh can support the silicon wafer assembly, allowing the silicon wafer assembly to be suspended over a large area. At the same time, the transverse ventilation groove can increase heat dissipation efficiency, thereby effectively improving welding stability, preventing deformation of the silicon wafer assembly, and requiring minimal modification to the platform base, with good machine compatibility.

[0012] 2. This utility model improves the thermal conductivity by adding a metal mesh and an anti-stick coating to the breathable mesh fabric. The metal mesh can improve the thermal conductivity, and the anti-stick coating can make the silicon wafer assembly easier to demold, thereby further improving the welding quality.
