Tongwei Solar has obtained a patent for a silicon wafer insertion mechanism as well as solar cell production equipment, which can accommodate silicon wafers of various thicknesses.
On April 24, 2025, Financial界 reported that the National Intellectual Property Administration of China has officially granted a patent to Tongwei Solar (Pengshan) Co., Ltd. for a device titled “Silicon Wafer Insertion Mechanism and Solar Cell Production Equipment.” The patent announcement number is CN222785280U, with an application date of July 2024.
The patent abstract reveals that this invention pertains to the field of solar cell production technology, specifically focusing on a silicon wafer insertion mechanism and solar cell production equipment. The mechanism includes a mounting base and multiple clamping components. These clamping components are arranged vertically at intervals on the mounting base, creating gaps between adjacent clamping components. These gaps are designed to allow for the insertion of silicon wafers, ensuring that both sides of the wafers are securely positioned between the clamping components based on their thickness.
Each clamping component is movably connected to the mounting base and is configured to adjust vertically, thereby allowing for the modulation of the gap width. This silicon wafer insertion mechanism can be adjusted according to the thickness of the wafers, enabling the collection of wafers of various thicknesses.
According to Tianyancha data, Tongwei Solar (Pengshan) Co., Ltd. was established in 2020 and is located in Meishan City. The company primarily engages in the manufacturing of electrical machinery and equipment, with a registered capital of 2 billion RMB. Analysis from Tianyancha indicates that the company has participated in 28 bidding projects and holds 31 patents, in addition to possessing 208 administrative licenses.
