In this embodiment, the air-floating board turnover device has a first working state and a second working state. Referring to fig. 1 to 3, when the air-floating plate device is in the first working state, the first bearing surface 410a and the second bearing surface 420a extend along the horizontal direction, the first bearing surface 410a and the second bearing surface 420a are disposed at intervals along the up-down direction Z, and the first bearing surface 410a and the second bearing surface 420a are disposed on the up-down sides of the rotation center line 1001 respectively. At this time, a transmission channel is formed between the first bearing surface 410a and the second bearing surface 420a, the transmission channel extends along the second direction Y, and the limiting member is located in the transmission channel and is used for limiting the transmission direction of the workpiece 1. It should be noted that, in the drawing of this embodiment, a case where the first bearing surface 410a is located below the second bearing surface 420a is illustrated, and at this time, the first bearing surface 410a is supported below the workpiece 1, and the air supply device supplies air to each air floatation port 21 of the first platform 410; when the turning base 200 rotates 180 ° around the rotation center line 1001, the air floating plate device can be in the first working state, and the first bearing surface 410a is located above the second bearing surface 420a, and the second bearing surface 420a is used for supporting the workpiece 1, and the air supply device supplies air to each air floating opening 21 of the second platform 420. In other embodiments, if only one of the first platform 410 and the second platform 420 is provided with the air-floating mechanism, when the air-floating plate device is in the first working state, the one provided with the air-floating mechanism is located below.

When the air-floating plate turnover device is in the second working state (not shown), the first bearing surface 410a and the second bearing surface 420a are close to each other and can clamp the workpiece 1, the air supply device stops supplying air, and at this time, the turnover mechanism 300 can drive the turnover seat 200 and the clamp transmission mechanism 400 thereon to rotate around the rotation center line 1001, so that the workpiece 1 is turned.

The working principle of the air-float plate turnover device in this embodiment is specifically described below:

firstly, the air-float plate turnover device is adjusted to a first working state, the air supply device is started, and the limiting piece is lowered into place. Subsequently, the operator can push the workpiece 1 to be inverted into the working space 201 step by step manually or by means of a mechanical conveying device. When the workpiece 1 just begins to contact the first platform 410 below, under the action of gravity of the workpiece 1, the air-floating beads 22 contacted by the workpiece 1 are pressed down, the air-floating beads 22 are blown upwards corresponding to the high-pressure air flow in the inner cavity 21a, so that upward supporting force can be provided for the workpiece 1, the workpiece 1 is separated from the first bearing surface 410a, the pressure between the workpiece 1 and the air-floating beads 22 below is smaller, and the rolling friction force between the workpiece 1 and the air-floating beads 22 is smaller. When the workpiece 1 is heavier, the displacement of the air-floating bead 22 pressed down is larger, so that the opening degree of the air-floating opening 21 is larger, wherein the blown air flow is larger, so that a larger air-floating supporting force can be provided for the workpiece 1, and the air-floating effect is ensured. After that, the operator or the transmission device can continue to push the workpiece 1 along the second direction Y, and the pushing becomes easy, simple and quick due to smaller friction force, and the plate surface pollution caused by excessive friction can be effectively avoided.

When the workpiece 1 is pushed to the preset station of the first platform 410, the air supply device is turned off, and the air-floating plate turnover device is converted into a second working state. At this time, the second clamping cylinder 440 drives the second stage 420 to descend until the second bearing surface 420a abuts against the upper surface of the workpiece 1. In some embodiments, the first platform 410 may also be synchronously driven up by the first clamping cylinder 430. After the workpiece 1 is stably clamped, the driving device 330 starts to drive the first shaft 310 to rotate, and the second shaft 320 synchronously rotates, and jointly drives the turning seat 200 to rotate about 180 degrees around the rotation center line 1001 until the first platform 410 rotates to be right above the second platform 420.

After that, the air-floating plate turnover device is converted into the first working state again, the first platform 410 is lifted upwards, the first bearing surface 410a and the second bearing surface 420a are away from each other and form a transmission channel again, and the air supply device is turned on again. At this time, the operator or the conveying device can continuously push the turned workpiece 1 out of the second platform 420 along the second direction Y, and the blanking is easily completed under the auxiliary force of the air floatation mechanism.

To sum up, the air-float plate turnover device provided by the embodiment can realize the efficient turnover of the large-size plate-shaped workpiece 1, greatly reduce the friction force between the workpiece 1 and the bearing platform, enable the loading and unloading movement of the workpiece 1 to be easy and labor-saving, and simultaneously remarkably reduce dust pollution caused by platform friction, meet the requirements of dust-free grades and improve the product quality.
