The lower fixture is provided with a third protrusion and a fourth protrusion, the gap between the third protrusion and the fourth protrusion constitutes a lower slot for positioning the glass, and the height of the third protrusion is greater than that of the fourth raised height;

When the glass is placed on the upper fixture and the lower fixture, there is a distance between the glass and the groove bottom of the upper clamping groove of the upper fixture.

The lower card slot is V-shaped.

When the glass is placed on the upper fixture and the lower fixture, the distance between the glass and the groove bottom of the upper clamping groove of the upper fixture is 2-3mm.

The depth of the upper card slot is 8.5 mm, and the depth of the lower card slot is 3 mm.

The upper clamp and the lower clamp are provided with bolt holes, and the upper clamp and the lower clamp are connected with the substrate frame by bolts.

One of the above-mentioned technical solutions has the following advantages or beneficial effects. The upper and lower clamps are designed into a V-shaped structure, and the original clamp position mounting holes on the workpiece vehicle are used for fixing, without the need to fix the workpiece vehicle itself. The structure can realize fast loading and unloading of glass after redesigning and processing. The upper fixture is designed with a spacing margin, which is convenient for the quick loading and unloading of the glass. It is also designed with higher first bumps and third bumps to increase the contact area between the glass and the fixture, increase the stressed area of the glass, and prevent damage to the glass.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the implementation of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, a kind of substrate holder glass installation jig comprises upper jig 1 and lower jig 2, and upper jig 1 is provided with first protrusion 11 and second protrusion 12, first protrusion 11 and second protrusion The gap between 12 constitutes the upper slot 13 for positioning the glass 3, and the height of the first protrusion 11 is greater than the height of the second protrusion 12;

The lower fixture 2 is provided with a third protrusion 21 and a fourth protrusion 23, the gap between the third protrusion 21 and the fourth protrusion 23 constitutes the lower slot 22 for positioning the glass 3, and the height of the third protrusion 21 is greater than The height of the fourth protrusion 23 is designed with a higher first bump and a third bump to increase the contact area between the glass 3 and the fixture, increase the stress area of the glass 3, and prevent the glass 3 from being damaged.

When the glass 3 is placed on the upper fixture 1 and the lower fixture 2 , there is a distance between the glass 3 and the bottom of the upper clamping groove 13 of the upper fixture 1 . The designed spacing margin is to facilitate the quick loading and unloading of the glass 3 .

The lower card slot 22 is V-shaped. It is convenient to place the glass 3 and also increases the contact area between the glass 3 and the lower fixture 2 .

When the glass 3 is placed on the upper fixture 1 and the lower fixture 2, the distance between the glass 3 and the groove bottom of the upper clamping groove 13 of the upper fixture 1 is 2-3 mm.

The depth of the upper card slot 13 is 8.5mm, and the depth of the lower card slot 22 is 3mm. The upper draw-in groove 13 and the lower draw-in groove 22 only contact with the edge of the glass 3, and do not touch the liquid crystal part in the glass 3, preventing the damage of the lower draw-in groove 22 to the glass 3 liquid crystal part.

Both the upper clamp 1 and the lower clamp 2 are provided with bolt holes, and the upper clamp 1 and the lower clamp 2 are connected with the substrate frame by bolts. Easy to assemble and disassemble.
