Description

Technical Field

[0001] This utility model relates to the field of spin coating equipment technology, and in particular to a high-precision spin coating machine for producing solar cells. Background Technology

[0002] In the fabrication of perovskite solar cells, the spin coating process is a crucial step, responsible for uniformly coating materials such as photoresist onto the substrate surface. However, existing spin coating equipment used in perovskite solar cell production generally suffers from problems such as insufficient coating uniformity, poor adaptability to substrates of different specifications, lack of ease of operation, and weak protective measures. These issues restrict the production quality and efficiency of perovskite solar cells, making it difficult to meet the industry's demand for high-precision, high-performance spin coating. Therefore, the development of a high-performance spin coating machine specifically designed for perovskite solar cell production is imperative. Utility Model Content

[0012] Preferably, the metal pot is also connected to a support, on which a vertically arranged telescopic rod is installed. The lowest end of the telescopic rod is connected to a glue-spreading nozzle, which is located directly above the rotating platform.

[0013] The beneficial effects of this utility model are: This spin coater directly drives a rotating platform equipped with suction cups via an electric motor, ensuring direct and efficient power transmission. The motor bracket is symmetrically connected to the equipment casing via connecting rods and support plates, forming a highly stable support structure that effectively suppresses vibration during operation and ensures the high degree of stability of the rotating platform, providing a crucial foundation for high-precision spin coat application. The suction cup design ensures that the solar cell modules to be coated are firmly adhered and positioned, preventing displacement during high-speed rotation.

[0014] The metal pot is practically designed, attached to the motor bracket and surrounding the rotating platform. Its core function is to effectively isolate the rotating working area, preventing adhesives, solvents, or splashes from contaminating the motor, bracket, and other key components below, thus protecting the internal components of the equipment. Simultaneously, the metal pot can temporarily collect splashed adhesives or cleaning solvents, facilitating cleaning and maintenance.

[0016] The equipment's heat dissipation and stability have been fully considered. A fan mounted on the equipment casing, combined with several ventilation holes on both sides, forms an effective forced ventilation and heat dissipation system. This system effectively removes heat generated by the motor and electronic components, preventing overheating and ensuring stable long-term operation and extended service life. Anti-slip pads on the bottom of the casing increase friction between the equipment and its surface, effectively preventing displacement during operational vibrations and ensuring smooth and safe overall operation.

[0026] The equipment housing 2 has several heat dissipation holes 4 on both sides for heat dissipation, and buttons and a display screen are located at the front of the equipment housing 2. As a preferred solution, the support plate 9 can be replaced by two finned heat sinks, the connecting rod 10 can be replaced by a heat dissipation pipe, and the motor bracket 7 can be made of copper to achieve efficient heat dissipation.

[0027] A transparent cover 1 is hinged to the outer casing 2 of the equipment, and a handle is provided on the transparent cover 1. Several anti-slip pads are provided on the bottom of the outer casing 2 of the equipment.

[0028] The metal pot 5 is also connected to a bracket, on which a vertically installed telescopic rod is mounted.

The telescopic rod is an electric telescopic rod with a power-off self-locking function. The bracket can also use existing technology. In addition, when the telescopic rod is shortened, it does not affect the opening and closing of the transparent cover 1.

[0029] The spin coater directly drives the rotating platform 6, which is equipped with suction cups 11, via an electric motor 8, ensuring direct and efficient power transmission. The motor bracket 7 is symmetrically connected to the equipment housing 2 via connecting rods 10 and support plates 9, forming a very stable support structure that effectively suppresses vibration during operation and ensures the high stability of the rotating platform 6, providing a crucial foundation for high-precision spin coating.
