Description

Technical Field

[0001] The utility model relates to the technical field of touch screen manufacturing, in particular to an anti-wear touch screen substrate cleaning device. Background Art

[0002] As touch screen products on the market tend to be thinner and lighter, customers require touch screen substrates to be as thin as possible. When cleaning thin glass substrates, when the glass substrates are placed horizontally on the cleaning machine, the glass substrates will have a large curvature and are very prone to cracking. In addition, if the curvature of the glass substrate is large, the middle of the glass substrate will first contact the guide wheel, causing high local pressure on the glass substrate, which will eventually cause damage and scratches to the glass substrate, resulting in the scrapping of the glass substrate.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that the Chinese patent publication number: CN211802735U discloses an anti-wear touch screen substrate cleaning device, including a feeding platform, a cleaning platform and a drying platform. The cleaning platform is located between the feeding platform and the drying platform. A feeding conveying roller is provided in the No. 1 arc groove. A No. 1 motor for driving the feeding conveying roller is installed on the side wall of the No. 1 arc groove. The cleaning platform includes a cleaning box with an opening on the top surface. The surfaces of the feeding conveying roller, the lower cleaning conveying roller and the upper cleaning conveying roller of the utility model are all provided with a silicone rubber layer, thereby reducing the wear on the touch screen substrate during transportation; the touch screen substrate is ultrasonically cleaned in the cleaning box, solving the problem that the touch screen substrate is easily damaged and scratched. In addition, the touch screen substrate is dried at the same time after cleaning, so as to prevent the touch screen substrate from being contaminated with dust when it is transferred to the next drying process, thereby improving the cleanliness of the touch screen substrate.

[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is that the silicone rubber layer arranged on the surface of the feed conveyor roller, the lower cleaning conveyor roller and the upper cleaning conveyor roller will cause a certain degree of wear during use. It is difficult to replace after wear, and the replacement is cumbersome and laborious, which leads to the problem of wear on the touch screen substrate during transportation.

[0006] To this end, we propose an anti-wear touch screen substrate cleaning device to solve the above-mentioned drawbacks. Utility Model Content
