The side surface of the mounting plate 32 is provided with an opening 33, the opening 33 is arranged in the center of the mounting plate 32 and has the shape which is approximately the same as that of the mounting plate 32, and the opening 33 can reduce the mass of the mounting plate 32 under the condition of ensuring the strength of the mounting plate 32, thereby reducing the total mass of the glass positioning device.

Preferably, as shown in fig. 7 and 8, in the embodiment, the positioning part 5 includes a connecting member 52 and two positioning members 51. The connecting member 52 may be an angle steel (the angle steel is two metal plates perpendicular to each other and integrally formed, and hereinafter, these two metal plates are referred to as the edge of the angle steel). One end of the connecting piece 52 is fixedly connected with the mounting rack 4, a threaded hole can be formed at the bottom end of the connecting piece 52, a threaded hole which can be matched with the bottom end of the connecting piece 52 is formed at the position of a second group of opposite angles of the mounting rack 4, a triangular bottom plate is arranged between the connecting piece 52 and the mounting rack 4, a threaded through hole which can be matched with the bottom end of the connecting piece 52 is formed in the triangular bottom plate, and the three are connected through bolts. The positioning member 51 may be a "T" shaped member (the "T" shaped member is a member having a "T" shaped cross section, and includes a vertical portion and a horizontal portion, which are hereinafter referred to as a vertical portion and a horizontal portion), the "T" shaped member is transversely disposed at the top end of the connecting member 52, the vertical portion is horizontally disposed on the top end of the connecting member 52, the horizontal portion is disposed in the right angle of the connecting member 52, the two positioning members 51 are symmetrically disposed at the top ends of the two sides of the angle steel along the bisector of the right angle of the angle steel, and the height of the highest position of the positioning member 51 does not exceed the height of the top surface of the positioning roller 13.

In addition, it is preferable that the positioning members 51 are slidable at the top end of the connecting member 52, and the sliding directions of both the positioning members 51 are perpendicular to the side of the connecting member 52 on which the positioning members 51 are mounted, in which case the sliding directions of both the positioning members 51 are perpendicular to each other. A fitting hole 511 may be formed in a vertical portion of the spacer 51, the fitting hole 511 may be a waist-shaped hole having a longitudinal direction perpendicular to a side of the connector 52, and a screw hole having a diameter equal to a width of the fitting hole 511 may be opened at a position corresponding to the fitting hole 511 of each spacer 51 at a distal end of the connector 52. In use, the bolt is passed through the fitting hole 511 to be fixed in the threaded hole, and when the positioning member 51 is slid on the tip end of the connecting member 52, the bolt is slid in the fitting hole 511 along the length direction of the fitting hole 511 relative to the fitting hole 511. This allows adjustment of the distance between the lateral portion of the spacer 51 and the side of the link 52. A nut (not shown) is connected to a portion of the bolt exposed from the positioning member 51, and when the positioning member 51 is adjusted to a predetermined position, the nut is tightened to be fixed to the upper surface of the vertical portion of the positioning member 51, and the positioning member 51 is abutted and fixed. Preferably, the distance between the lateral portions of the spacers 51 and the glass after the desired positioning is 0.5mm (corresponding to the positioning accuracy).

During positioning, the glass-bearing plane of the air-floating platform is located within the height range between the top end and the bottom end of the transverse portion of the positioning member 51. There is a degree of skewing during the downward motion of the glass as it is placed in the loading plane of the air bearing platform, which may be placed on top of the lateral portions of the spacer 51. Since the height of the highest position of the positioning member 51 does not exceed the height of the top surface of the positioning roller 13, the positioning of the glass by the adjusting mechanism 6 is not affected whether the glass is placed on the air flotation platform or on the top end of the lateral portion of the positioning member 51. When the glass falls on the top end of the transverse part of the positioning member 51, the adjusting mechanism 6 still drives the glass in the positioning manner of the above embodiment, the glass is pushed away from the top end of the transverse part of the positioning member 51 and then moves onto the air floatation platform, at this time, the angle of the glass is located inside the right angle of the connecting member 52, and in order to enable the glass to be easily pushed away from the top end of the transverse part of the positioning member 51, the upper half part of the transverse part of the positioning member 51 is narrow at the top and wide at the bottom to form a certain gradient, so that the glass can conveniently slide down along the surface of the positioning member. Thereafter, when the glass is displaced during the driving of the glass by the adjusting mechanism 6, the edge of the glass comes into contact with the lateral portion of the positioning member 51, so that the moving range of the glass is restricted during the positioning process, and the glass does not go beyond the predetermined range when the positioning is completed. In order to prevent the positioning member 51 from damaging the glass when contacting the glass, the positioning member 51 is made of PEEK.

In practical application, the mounting frame 4 is installed in a cavity of the UV light curing machine, and the glass is placed on a PIN mechanism of the UV light curing machine by a robot hand and synchronously descends to reach the air floatation platform along with the PIN mechanism. When it is detected that the glass has reached the air-float platform, the two adjustment mechanisms 6 located in a first set of diagonal positions of the glass start positioning the glass. Before the adjusting mechanisms 6 are positioned, the length of the sliding block 113 extending out of the connecting groove 112 is adjusted, so that the relative positions of the two positioning rollers 13 on the same adjusting mechanism 6 are adjusted to preset positions, and therefore, after the adjusting mechanisms 6 are positioned, the two adjusting mechanisms 6 at the first group of diagonal positions of the glass cannot simultaneously extrude the glass, and the glass still keeps a certain moving margin. The cylinder mechanism of the telescopic part 2 of the adjusting mechanism 6 is adjusted to enable the piston rod to extend out of the cylinder body 211, the piston rod drives the second connecting part 212 to move towards the direction far away from the glass, and the adjusting part 1 moves to the maximum stroke position synchronously along with the second connecting part 212. After that, the glass reaches the air floating platform, the moving parts 21 of the two adjusting mechanisms 6 simultaneously retract the piston rods to drive the respective second connecting parts 212 to move along the direction of the ideal angular bisector of the positioned glass, and the adjusting parts 1 of the two glass positioning devices are in contact with the glass to drive the glass to move towards the designated section. In the positioning process, the two positioning parts 5 positioned at the second group of opposite corners of the glass limit the moving range of the glass, when the glass is inclined too much in the driving process, the glass is abutted against the positioning part 51, so that the positioning precision of the glass is ensured, and when the piston rod is completely retracted into the cylinder mechanism, the glass is driven to a specified interval to complete the positioning.
