Problems solved by technology

[0006] According to the above, in order to solve the problem that the traditional substrate transfer device is easy to break the glass substrate due to uneven stress or the device itself is not easy to maintain long-term operation, the present invention uses the principle of magnetic levitation and magnetic mutual repulsion to attract the transfer device to reduce the glass substrate. Various transmission problems caused by the increase in substrate size

Embodiment Construction

[0031] The substrate transfer device of the present invention will be explained in detail below with reference to various embodiments and accompanying drawings.

[0032] Please refer to FIG. 2 , which shows a side view of a glass substrate conveying device according to a preferred embodiment of the present invention. The glass substrate conveying device 200 includes a carrying platform 202 and a conveying track 208 , and a glass substrate 210 is placed on the carrying platform 202 . The carrying platform 202 has magnetic blocks 204 , 206 with different fixed magnetic properties alternately disposed under the carrying platform 202 . In this embodiment, the magnetic block 204 is N-pole magnetic, and the magnetic block 206 is S-polar magnetic; of course, vice versa is also possible.

[0033] The conveying track 208 is magnetic blocks 212 , 214 with variable magnetic properties, wherein the magnetic blocks 212 , 214 may have different magnetic properties. Please refer to Fig. 3,...

Abstract

This invention relates to a placode transmission device, which includes the following structure: the first magnetic section with different fixing magnetic are arranged on the carrying platform that are of its two sides, and the second magnetic section with two groups of various magnetic are arranged in the transmission rail of its two sides, wherein the distance between the second magnetic section is longer than the width of carrying platform, and the repulsion between the second magnetic section and the first magnetic section makes the carrying platform float on the transmission rail and move freely in the specific direction by changing the magnetic section's magnetic.

Description

technical field [0001] The present invention relates to a substrate transfer device, and in particular to a transfer device suitable for large-size substrates. Background technique [0002] In recent years, in order to reduce the production cost of flat-panel displays (such as liquid crystal displays or organic electroluminescence displays), the size of the glass substrate must be enlarged to facilitate the most economical cutting. Although the size of the glass substrate increases and the weight increases, the thickness of the glass substrate is getting thinner and thinner, and the glass substrate is becoming more and more fragile and easy to break, which makes the transfer of the substrate more challenging. [0003] FIG. 1 shows a schematic top view of a conveying device that carries and transports substrates in a traditional manufacturing process machine and moves or shakes forward or backward according to the requirements of the manufacturing process. The transmission d...
