Problems solved by technology

[0003] The float TFT-LCD glass substrate is cut, edged and cleaned in the front section, and then sent to the surface grinder by rollers for surface grinding. The existing transmission method is easy to produce roller marks on the surface of the float TFT-LCD glass substrate Dirty, when the float TFT-LCD glass substrate is transported to the surface grinding machine and then the glass substrate is attached to the machine, in this process, in order to meet the grinding accuracy, the bonding time is long, resulting in the utilization of the machine decline

Abstract

The invention discloses an automatic operation conveying device for surface grinding of float TFT-LCD glass. The automatic operation conveying device comprises magnetic suspension conveying devices, electromagnetic braking systems and a closed dust-free channel, wherein the closed dust-free channel is composed of a closed hood, the magnetic suspension conveying devices are installed at the lower end of the closed hood, the closed dust-free channel is obliquely downward, and the multiple magnetic suspension conveying devices are arranged from left to right to form a conveying track which is sealed by the closed hood; and a glass substrate is installed on the magnetic suspension conveying devices and moved and conveyed in the closed dust-free channel, and the electromagnetic braking systemsfor controlling the magnetic suspension conveying devices to brake are arranged in the magnetic suspension conveying devices. The cleaned float TFT-LCD glass substrate is attached to a suction pad tray and then conveyed in the closed hood in a magnetic suspension manner, so that the machine utilization rate can be increased, and meanwhile, roller marks and dirt cannot be generated on the surface of the float TFT-LCD glass substrate in the conveying process.

Description

technical field [0001] The invention relates to the technical field of TFT-LCD glass, in particular to an automatic transmission device for surface grinding of float TFT-LCD glass. Background technique [0002] The float TFT-LCD glass substrate is thinned and formed on the tin bath by pulling the edge pulling machine. Compared with the tin surface and the air surface in contact with the tin liquid, the surface roughness and waviness can reach up to 10 μm, which cannot meet the TFT- The LCD panel manufacturing process requires a roughness and waviness of less than 1 μm, so in the back-end process, surface grinding needs to be added to make the surface roughness and waviness of the glass meet the requirements of the panel manufacturing process. [0003] The float TFT-LCD glass substrate is cut, edged and cleaned in the front section, and then sent to the surface grinder by rollers for surface grinding. The existing transmission method is easy to produce roller marks on the sur...
