However, the above-mentioned device still has obvious defects: the abutting surface of the above-mentioned device is fixed, and it is easy to form offset marks on the surface of the liquid crystal panel during the long-term test abutment process, thereby affecting the surface cleanliness of the liquid crystal panel. At the same time, the function of the above-mentioned device is relatively single, and it can only achieve the pressing and fixing of the liquid crystal substrate. Summary of the invention

[0004] The object of the present invention is to provide a method for solving the problems mentioned in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

A telescopic groove is provided in the roller body for the pressing rubber strip to be telescopically embedded. A telescopic mechanism is provided in the telescopic groove to drive the pressing rubber strips on both sides to perform telescopic movements synchronously. When the arc-shaped rubber roller surface abuts against the glass substrate, the rotation of the rotating motor causes the glass substrate to move, thereby causing the glass substrate to move into the detection area. When the pressing rubber strip abuts against the glass substrate, the glass substrate is fixed, thereby facilitating the lighting test.

[0010] A roller surface cleaning area is also provided in the pressing roller cabin, and cleaning agent and dry air are released into the roller surface cleaning area to clean the arc-shaped rubber roller surface and the pressing rubber strip.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-7 , the present invention provides a technical solution:

[0028] Embodiment 1:

[0029] A bare glass inspection jig with multi-point positioning includes a limit plate 1, a guide rail 2 is fixedly mounted on the limit plate 1, and a plurality of positioning slide blocks 3 are arranged on the guide rail 2 in a translationally slidable manner;

[0030] A plurality of positioning slide blocks 3 are provided with telescopic adjustment slots at the front ends, which are plug-in matched with the telescopic rod body section of the telescopic adjustment block 4. A pressure plate assembly block 5 is fixedly installed at the front end of the telescopic adjustment block 4. A pressing plate 6 is provided on the pressing plate assembly block 5 for lifting. A pressing roller cabin 7 is provided at the bottom of the pressing plate 6. A pressing roller 8 is rotatably installed in the pressing roller cabin 7 with a fixed axis.

[0031] The axis of the clamping roller 8 is also connected to the driving shaft of the rotary motor. The rotation of the rotary motor drives the clamping roller 8 to perform reciprocating rotation. The rotary motor is fixedly installed in the clamping plate 6.

[0032] The pressing roller 8 is composed of a roller body 9, an arc-shaped rubber roller surface 10 and a symmetrical and telescopic pressing rubber strip 11 on both sides. A telescopic groove 12 is provided in the roller body 9 for the pressing rubber strip 11 to be telescopically embedded. A telescopic mechanism is provided in the telescopic groove 12 to drive the pressing rubber strips 11 on both sides to perform telescopic movements synchronously. When the arc-shaped rubber roller surface 10 abuts against the glass substrate, the rotation of the rotating motor causes the glass substrate to move, thereby causing the glass substrate to move into the detection area. When the pressing rubber strip 11 abuts against the glass substrate, the glass substrate is fixed so as to facilitate the lighting test.

[0033] A roller surface cleaning area 13 is also provided in the pressing roller cabin 7 , and cleaning agent and dry air are released into the roller surface cleaning area 13 so as to clean the arc-shaped rubber roller surface 10 and the pressing rubber strip 11 .

[0034] In this embodiment, the limit plate 1 is fixedly installed, and a guide rail 2 is laid on it. The positioning slider 3 slides in translation on the guide rail 2. The mechanism of its translational movement can adopt a rubber wheel driving mechanism, a pneumatic or linear driving motor. Since it is widely used in the prior art, it will not be described in detail here. The positioning slider 3 is plug-in matched with the telescopic adjustment block 4. After the plug-in is completed, it is limited and fixed by abutting against a nut. Since it is connected in a plug-in manner, it can adjust the telescopic length. A pressure plate assembly block 5 is installed at the front end of the telescopic adjustment block 4. The pressure plate 6 can be lifted and lowered on the pressure plate assembly block 5, thereby realizing the lifting and lowering movement of the pressure roller 8. The mechanism driving the pressure plate 6 to lift and lower is a pneumatic slider mechanism, thereby completing the lifting and lowering movement adjustment of the pressure plate 6. The pressure roller 8 can also rotate under the drive of a rotating motor. The pressure roller 8 is composed of a roller body 9, an arc-shaped rubber roller surface 10 and a pressure rubber strip 11 symmetrically and telescopically arranged on both sides. When the arc-shaped rubber roller surface 10 abuts against the glass substrate, the rotation of the rotating motor causes the glass substrate to move, thereby causing the glass substrate to move into the detection area. When the pressing rubber strip 11 abuts against the glass substrate, the glass substrate is fixed so as to facilitate the lighting test. The above method can realize the clamping, fixing and position adjustment operations of the glass substrate. Compared with the related devices in the prior art, the functions are more diverse. A roller surface cleaning area 13 is also provided in the pressing roller cabin 7. The arc-shaped rubber roller surface 10 and the pressing rubber strip 11 are cleaned by releasing cleaning agent and dry wind into the roller surface cleaning area 13. Such a setting is conducive to keeping the contact area between the arc-shaped rubber roller surface 10 and the pressing rubber strip 11 and the glass substrate clean, thereby reducing the surface defect rate of the glass substrate. The number of the positioning sliders 3 is 5, so that it can work alone or in combination, so that glass substrates of different sizes can be clamped or position adjusted.

[0035] Embodiment 2:

[0036] The telescopic mechanism that drives the compression strips 11 on both sides to perform synchronous telescopic movement includes an extrusion spring 14 and a telescopic airbag 15. On a mounting plate 16 fixedly arranged in the telescopic groove 12, the extrusion spring 14 and the telescopic airbag 15 are symmetrically arranged along the two sides of the mounting plate 16. The extrusion spring 14 is used to push the compression strips 11 on both sides to the outside of the telescopic groove 12 without the action of external force. The telescopic airbag 15 contracts by exhausting air, thereby pulling the compression strip 11 to overcome the elastic force of the extrusion spring 14 and contracting into the telescopic groove 12. The telescopic airbag 15 is connected to an external pumping air device through a pipeline through an air inlet and outlet hole 17 opened at the axis of the compression roller 8.

[0037] In this embodiment, a telescopic driving mechanism of the compression strips 11 on both sides is further disclosed, which protrude outward under the elastic force of the extrusion spring 14, and shrink during the air extraction process of the telescopic airbag 15 to enter the telescopic groove 12. The telescopic airbag 15 is connected to an external pumping device through a pipeline through the air inlet and outlet holes 17 opened at the axis of the roller body 9, thereby performing a pumping operation.

[0038] Embodiment three:

[0039] The roller surface cleaning area 13 is provided with a detergent inlet and outlet channel 18 and an air drying channel 19. The detergent inlet and outlet channel 18 is connected to an external circulating liquid supply pump for circulating detergent filling, and the air drying channel 19 is connected to an external pump air device for dry cleaning.

[0040] In this embodiment, the corresponding structure for releasing detergent and drying air into the roller surface cleaning area 13 is further disclosed, and the detergent is circulated and filled by connecting with an external circulating liquid supply pump, and the air drying channel 19 is connected with an external pump air device to perform dry cleaning.

[0041] Embodiment 4:

[0042] A compression rubber strip receiving groove 20 is also provided in the compression roller cabin 7 , and the compression rubber strip receiving groove 20 is used for receiving the compression rubber strips 11 on both sides.

[0043] In this embodiment, a compression rubber strip receiving groove 20 is further provided in the compression roller cabin 7 to receive the compression rubber strip 11, so that the compression rubber strip 11 is received in the compression rubber strip receiving groove 20 when not in operation, thereby preventing the surface of the compression rubber strip from being stained.

[0044] Embodiment five:

[0045] The pressing roller cabin 7 is also provided with a cleaning area 21 which is arranged close to the arc-shaped rubber roller surface 10 , and the surface is cleaned by the contact between the cleaning area 21 and the arc-shaped rubber roller surface 10 and the pressing rubber strip 11 .

[0046] In this embodiment, the abutting cleaning area 21 is further provided to make it closely attached to the outer surface of the arc-shaped rubber roller surface 10 and the outer surface of the accommodated pressing strip 11. During the rotational drive of the rotating motor, the pressing roller 8 reciprocates to make the arc-shaped rubber roller surface 10 and the pressing strip 11 contact with the abutting cleaning area 21 to perform surface cleaning. With the release of the cleaning medium and the air-drying medium, further surface operations can be performed.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
