Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as Figure 1-4 As shown, a non-contact air flotation transport device for glass substrates includes a base 3 on which an air flotation guide rail 2 is connected via a leveling screw 4 to realize level adjustment of the platform, and the air flotation guide rail 2 is The array is provided with several grooves 11, the cross-section of the grooves 11 is square or rectangular, the depth of the grooves 11 is greater than 100 microns and less than 300 microns, and there are four vent holes of the same size symmetrically distributed inside the grooves 11, Two of them are air inlet holes 8, and the remaining two are air outlet holes 13. Both sides of each groove 11 are provided with a pressure equalizing groove 10, and the air inlet 8 and the air outlet 13 are arranged in the pressure equalizing groove 10. The width of the pressure equalizing groove 10 is slightly...

Abstract

The invention discloses a glass substrate non-contact air flotation transportation device, which includes an air flotation guide rail, the air flotation guide rail is arranged on a base, and its levelness can be adjusted, and a plurality of grooves are arranged in an array on the air flotation guide rail , the two sides of the bottom of the groove are correspondingly provided with an air inlet and an air outlet, and an air outlet is arranged in the groove, and the air inlet is connected to the positive pressure air pipe through a three-position five-way valve, and the air outlet is passed through The three-position five-way valve is connected to the negative pressure air pipe, and the exhaust hole is connected to the negative pressure air pipe. The present invention utilizes the viscous effect generated by air flow as the driving force to realize the real complete non-contact, the glass substrate is not easy to be polluted or damaged, the influence of the air flow in the vertical direction is not significant, and the disturbance of the air flow to the workpiece can be reduced. Paired air supply holes and air suction holes in the groove are connected, which can reduce the occurrence of turbulent flow in the groove and further increase the viscous traction driving force.

Description

technical field [0001] The invention relates to a glass substrate transportation device, in particular to a glass substrate non-contact air flotation transportation device. Background technique [0002] Flat panel display technologies represented by liquid crystal displays are widely used in people's daily production and life. In the production and manufacturing process of flat panel display glass substrates, there are many processes and various inspection links, so that the glass substrates must be frequently transported to various working links. Concentration and other reasons cause damage. The traditional liquid crystal glass substrate transmission adopts the contact transportation method, that is, the workpiece is in direct contact with the surface of the transportation device and driven by rollers, which is likely to cause scratches and cracks on the surface of the glass substrate. At the same time, there are Many problems such as static electricity and metal pollution...
