[0032] By installing the moving mechanism 10 on the ceiling and connecting the moving plate 11 to the moving mechanism 10, the moving mechanism 10 can drive the moving plate 11 to move, thereby adjusting the position of the moving plate 11; by installing the lifting mechanism 12 on the moving plate 11 and connecting the lifting plate 13 to the lifting mechanism 12, the lifting mechanism 12 and the moving plate 11 can move synchronously, thereby enabling the lifting mechanism 12 to drive the lifting plate 13 to move up and down, thereby adjusting the height of the lifting plate 13. By installing the adjustment mechanism 14 on the lifting plate 13, connecting two L-shaped first support plates 16 to one end of the adjustment mechanism 14 simultaneously, and connecting two L-shaped second support plates 17 to the other end of the adjustment mechanism 14, the adjustment mechanism 14 and the lifting plate 13 can move synchronously, thereby enabling the adjustment mechanism 14 to drive the first support plates 16 and the second support plates 17 to move, thus adjusting the distance between the first support plates 16 and the second support plates 17; by installing four vacuum suction cups 18 on the front and rear sides of the lifting plate 13, the lifting plate 13 supports the four vacuum suction cups 18, thereby enabling the four vacuum suction cups 18 to adsorb the board material, and thus realize the handling of the board material.

[0033] In actual use of the product, firstly, activate the moving mechanism 10 to move the moving plate 11, thereby positioning the lifting plate 13 above the material to be transported; then, activate the lifting mechanism 12 to move the lifting plate 13 downwards, causing the four vacuum suction cups 18 to come into contact with the top of the material, thus allowing the four vacuum suction cups 18 to adhere to the material; next, activate the lifting mechanism 12 to move the material upwards; when the material is a certain distance from its initial position, activate the adjusting mechanism 14 to move the two first support plates 16 and two second support plates 17 relative to each other, thereby positioning the two first support plates 16 and two second support plates 17 below the material, thus protecting the material; then, activate the moving mechanism 14 to move the lifting plate 13 downwards, thereby protecting the material. The moving mechanism 10 drives the moving plate 11 and the plate to move (during the movement, the four vacuum suction cups 18 remain in an adsorption state); when the plate moves to the predetermined position, the lifting mechanism 12 is activated, causing the lifting mechanism 12 to drive the lifting plate 13 and the plate to move downward; when the plate is a certain distance from the predetermined position (this distance is slightly greater than the thickness of the bottom surface of the first support plate 16 and the second support plate 17); the adjusting mechanism 14 is activated, causing the adjusting mechanism 14 to drive the first support plate 16 and the second support plate 17 to move to both sides, thereby moving the first support plate 16 and the second support plate 17 out from under the lifting plate 13; then, the lifting mechanism 12 is activated, causing the lifting mechanism 12 to drive the lifting plate 13 and the plate downward, thereby placing the plate at the predetermined position.
