Yuhuan CNC Applied For A Patent Related To Glass Loading And Unloading Device, Which Realizes Adaptive Buffering And Smooth Separation Of Workpieces

Yuhuan CNC applied for a patent related to glass loading and unloading device, which realizes adaptive buffering and smooth separation of workpieces

When large-sized glass is being loaded and unloaded, if the workpiece is bumped, all the previous efforts will be wasted. This patent applied by Yuhuan CNC on June 10, 2026, uses a gas-liquid mixed film method to change the buffering effect into an adaptive one. In this way, it directly bypasses the rigid defects of traditional mechanical buffering.

Bottom wall structure and gas-liquid channel

There are evenly arranged buffer pores distributed on the working surface of the lower wall. Inside these buffer pores, flow channels with a tree-like structure are opened to guide the flow of liquid and gas. Through these flow channels, the water inlet blocks set on the side walls are connected so that the water can enter. On the water inlet block where the above-mentioned water inlet channels are located, there are specially set up independent water channel interfaces and air channel interfaces. The purpose of this design is to allow the water channel interface and the air pipe channel interface to be connected to deionized high-purity compressed air and pure water from the outside respectively.

The two media are mixed in the flow channel, and then escape from the pores, forming a gas-liquid film between the workpiece and the lower plate. The entire structure does not require additional sensors, but relies on the mixing ratio to automatically adjust damping. Its layout is compact.

Adaptive damping and soft landing

The size of the film damping force is proportional to the square of the instantaneous speed of the workpiece. If the incoming material is fast, the buffering force will be larger. If the incoming material is slow, the buffering force will be smaller. This method does not require presetting any parameters and can automatically match each impact situation.

When unloading, the CNC turning automatic loading and unloading device uses film pressure to directly overcome the vacuum adsorption force, so that the workpiece can be lifted up smoothly and separated. There is no need for mechanical clamps to contact the CNC turning automatic loading and unloading device during the entire process, thus avoiding damage to the glass edge due to rigid stress.

Revenue and Profit Status

In the first half of 2026, Yuhuan CNC achieved revenue of 181 million yuan, ranking 16th among 19 peer companies. This level is far lower than the industry average of 800 million yuan. Among them, grinding and polishing products accounted for 38.88% of the company's business structure, while CNC grinder products accounted for 30.84%.

Net profit attributable to the parent company was -24.1407 million yuan, ranking 16th among peers. This figure was lower than the industry average of 50.88 million yuan. The company was established in Changsha in 2004. Listed on the Shenzhen Stock Exchange in October 2017.

Patent details and concept layout

The list of inventors includes Liu Gengxin, Li Wei and Chen Yongfu. The agent is Li Linna. The classification numbers are G03F7/20 and G02B6/06. The technical focus is mainly on the loading and unloading of the glass of the semiconductor substrate when the size is relatively large.

The company currently has the triple conceptual identity of semiconductor equipment, third-generation semiconductors and Apple industry chain. The acquisition of this patent has made up for the previous shortcomings of the product matrix in the field of substrate handling.

Mass production prospects and competitive position

Today's display and optical substrates are getting larger. The traditional mechanical loading and unloading method can no longer handle the buffering and time rhythm issues at the same time. The gas-liquid membrane solution combines three steps. This method is more adaptable to glass production lines above 8 inches.

If Yuhuan CNC can successfully enter the mass production verification stage, its CNC turning automatic loading and unloading device production line will have a differentiated competitive trump card. However, whether the current operating income of 180 million yuan can support continued investment in R&D funds is still a question full of suspense.

The annual operating income of this machine tool company is less than 200 million yuan, but it only relies on a certain patented technology to get involved in the field of semiconductors .
