Air flotation conveying device

Abstract

The invention relates to an air flotation conveying device which comprises at least two conveying shafts and at least one air flotation conveying shaft and is used for conveying a bent and approximately sheet object to be detected to move. The object to be detected is provided with a contact surface and an operating surface; the conveying shafts are contacted with a contact surface of the object to be detected while the air flotation conveying shaft is adjacent to and not contacted with the operating surface of the object to be detected; and the object to be detected is limited by the air flotation conveying shafts to form a bending section between the two conveying shafts. Each air flotation conveying shaft is provided with an air storage space, an operating part, a non-operating part and an air intake part, wherein the air storage space is used for storing high-pressure gas; the operating part is adjacent and faces toward the operating surface without contacting and is provided with a plurality of exhaust holes; and the air intake part is used for conveying the high-pressure gas to enter the air storage space and sending the high-pressure gas out by the plurality of exhaust holes of the operating part to form an air cushion layer, therefore, a predetermined space is generated between the operating surface of the object to be detected and the operating part of the air flotation conveying shafts. The invention has the protection of the specified surface and is capable of carrying out non-contact tension adjustment.

Description

technical field [0001] The invention relates to an air-floating conveying device, in particular to an air-floating conveying device with an air-floating conveying shaft. Background technique [0002] In recent years, the light, thin, and short design trends of consumer electronics have become the driving force for the growth of the flexible printed circuit board market; ), notebook computers are its main application markets. [0003] Generally speaking, the flexible circuit board must use external force to achieve a certain tension during the transportation process, so that the flexible circuit board has a certain degree of flatness, such as figure 1 As shown, the existing conveying device 90 utilizes several rollers 91 arranged crosswise, so that the flexible circuit board 92 can generate a certain tension during the conveying process, thereby making the flexible circuit board 92 have a certain flatness; but the flexible circuit board The surface 921 with the circuit on t...

[0003] Generally speaking, the flexible circuit board must use external force to achieve a certain tension during the transportation process, so that the flexible circuit board has a certain degree of flatness, such as figure 1 As shown, the existing conveying device 90 utilizes several rollers 91 arranged crosswise, so that the flexible circuit board 92 can generate a certain tension during the conveying process, thereby making the flexible circuit board 92 have a certain flatness; but the flexible circuit board The surface 921 with the circuit on the top of 92 is easy to damage the circuit due to the pressure of contact. Therefore, the roller 91 has a certain pressure limit when conveying the flexible circuit board 92, and it is difficult to control the tension and flatness required by the flexible circuit board 92.
