Description

Technical Field

[0001] This invention belongs to the field of glass substrate testing, and particularly relates to a glass substrate surface roughness measuring instrument. Background Technology

[0002] The edges of glass substrates after cutting are relatively sharp and irregular. Edge grinding can ensure that the glass's geometry and tolerances meet requirements. Glass edge grinding generally begins with coarse, medium, and fine grinding wheels, followed by diamond edge grinding wheels to create a frosted surface. Some edges may also require polishing. If the surface roughness of the glass substrate edge is poor, the edge will not be smooth enough and may contain tiny dark cracks, leading to breakage. Currently, the main method for evaluating the surface roughness of glass substrates is through probe measurement using a roughness sensor, combined with clamping fixtures. However, once the glass substrate is fixed, the orientation of the measured surface cannot be guaranteed to be uniform. Therefore, the orientation of the roughness sensor needs to be adjusted. How to make the orientation adjustment of the roughness sensor applicable to any scenario has become a pressing technical problem. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned problems in the prior art and provide a glass substrate surface roughness measuring instrument.

[0011] The telescopic connecting seat is telescopically connected at one end to the other end of the telescopic adjusting seat, and the telescopic connecting seat and the telescopic adjusting seat are fixedly connected by an elastic locking component.

[0012] The rotating limiting component is rotatably installed on the telescopic adjustment seat, and its bottom is installed in conjunction with the elastic locking component.

The end of the elastic side plate has a limiting protrusion that cooperates with the limiting slot. The inner surface of the elastic side plate is evenly distributed with first meshing teeth. An adjusting protrusion is provided at the junction of the arc-shaped elastic plate and the elastic side plate, and an adjusting stop is provided vertically at the end of the adjusting protrusion.

[0026] The rotating limiting component includes a rotating adjusting block, the bottom end of which is provided with a fourth rotating connecting post that mates with a fourth rotating connecting hole, and the bottom end of the fourth rotating connecting post is provided with an eccentric cam.

[0027] The telescopic connecting seat includes a telescopic connecting strip and an outer connecting platform disposed at the outer end of the telescopic connecting strip. The telescopic connecting strip has second meshing teeth that mate with the first meshing teeth on both the left and right sides.

[0032] Furthermore, the fifth rotary connecting hole and the fifth rotary connecting post are in a transition fit.

[0033] The beneficial effects of this invention are:

[0034] This invention utilizes a rotating adjustment component to allow the lifting support seat to be adjusted to a predetermined height on the support frame. To ensure long-term fixation at the same height after adjustment, a positioning bolt can be tightened to form a secondary fastening connection between the lifting support seat and the support frame, preventing damage to the threaded structure of the lifting adjustment component. By loosening the fastening adjustment component and lifting the telescopic adjustment seat, it can be rotated to any desired angle. After adjustment, it falls back down under gravity, where it is limited by the engagement between the rotation limit groove and the rotation limit protrusion. A secondary limit is achieved by tightening the fastening adjustment component again. An elastic locking component engages and clamps both sides of the telescopic connecting strip in a free state. When telescopic adjustment is needed, simply rotate the rotation limit component to separate the elastic locking component from the telescopic connecting seat. The rotating support seat allows for horizontal rotation adjustment, and the angle adjustment seat allows for rotation adjustment perpendicular to the horizontal plane. Ultimately, this allows for arbitrary orientation adjustment of the roughness sensor as needed, meeting the requirements of any complex application scenario. Attached Figure Description
