The supporting structure 3 is mounted on the tray 2, a supporting surface of the supporting structure 3 is supported at a first preset position of the adhesive-substituted workpiece, the pressing structure 4 is mounted on the supporting frame 1, and a pressing surface of the pressing structure 4 abuts against a second preset position of the workpiece 100 to be positioned; the first preset position is located on one side surface of the workpiece 100 to be positioned, and the second preset position is located on the other side surface of the workpiece 100 to be positioned. That is to say, the supporting structure 3 and the pressing structure 4 respectively press the workpiece 100 to be positioned on the upper and lower surfaces, so as to realize the positioning of the two sides of the workpiece and ensure the positioning reliability.

In the working process, the workpiece 100 to be positioned is placed on the tray 2 and moves to the workpiece positioning device along the conveying line of the equipment along with the tray 2, the tray 2 stops moving at the positioning device, the supporting structure 3 and the pressing structure 4 respectively clamp the workpiece at the positions opposite to each other in the two vertical directions, and the clamping position is matched with the convex-concave position of the workpiece, so that the positioning effect is improved, the curved surface workpiece is prevented from moving in the gluing process, the stability of the workpiece is further improved, and the gluing quality is ensured.

Specifically, the first preset position is located on the lower surface of the workpiece 100 to be positioned, the second preset position is located on the upper surface of the workpiece 100 to be positioned, and projections of the first preset position and the second preset position on the surface of the tray 2 coincide with each other. Here, the projection coincidence is only used to indicate that the two preset positions of the clamping are on the same longitudinal axis, and the size and shape of the first preset position and the second preset position are not limited. The arrangement mode can further improve the clamping stability and reliability. In principle, the first predetermined position and the second predetermined position may also be offset from each other in the axial direction.

The first preset position and the second preset position are both located at the wave trough 101 of the workpiece 100 to be positioned, in the process of processing the curved glass, the curved glass is provided with a plurality of wave troughs 101, and the supporting structure 3 and the pressing structure 4 respectively press the same wave trough 101 at two sides so as to fix the same wave trough. The first preset position and the second preset position may also be located at a peak of the workpiece 100 to be positioned.

Since the curved workpiece usually has a plurality of wave troughs 101, for example, the curved glass has a wavy structure, there are a plurality of wave crests and a plurality of wave troughs, and the wave troughs 101 refer to wave trough positions, that is, concave towards the tray 2. The supporting structures 3 are multiple groups corresponding to the structures of multiple wave troughs 101 of the curved surface workpiece, and each group of supporting structures 3 is correspondingly arranged at each wave trough 101 of the workpiece 100 to be positioned.

In the working process, the initial position of the pressing structure 4 is the retraction state of the telescopic cylinder 41, the pressing block 42 is at the high position, and when the workpiece 100 to be positioned moves to the rubberizing position along with the tray 2, the telescopic cylinder 41 of the pressing structure 4 extends and drives the pressing block 42 to move downwards to a proper position so as to press the workpiece. For workpieces with different specifications, the extension stroke of the telescopic cylinder 41 can be adjusted to clamp the workpieces with different specifications, and meanwhile, when the workpiece needs to enter the next station, the pressing block 42 can move upwards under the action of the telescopic cylinder 41 to avoid interference on the workpiece, manual operation is not needed, and the labor intensity is reduced. The telescopic cylinder 41 may be in the form of an air cylinder, an oil cylinder or an electric cylinder.
