Abstract

The utility model relates to a glass thickness measuring instrument comprising a scale and a laser transmitter; a base is placed on the surface of the glass to be measured and provided with a flat bottom surface, and the bottom surface of the base is provided with a light-transmitting opening; one side of the light-transmitting opening on the base is fixedly provided with the scale which is vertical to the bottom surface; the laser transmitter is fixed at the other side of the light-transmitting opening on the base, namely, the opposite side of the scale; and the laser transmitted by the laser transmitter and the bottom surface form an included angle. The laser is obliquely irradiated on the glass; the upper surface and the back surface of the glass generate two times of reflection; the reflected light is projected on the scale; the distance of two light spots on the scale and the thickness of the glass are in direct proportion; and the scale is marked with corresponding scale values, namely the thickness of the glass can be read. The glass thickness measuring instrument has the advantages of simple structure and convenient use and is especially applicable to online monitoring of glass.

Description

The thickness of glass measuring instrument

Technical field

The utility model relates to measurer, especially for the instrument of Measuring Object thickness.

Background technology

Measuring the thickness of glass, generally is with slide calliper rule or milscale, and this is confined to there is not incrusted glass.In the measurement products finished product, during the thickness of glass part, because general gage measuring can't use in the limit of not exposing, can only place object of reference, in thickness measuring apparatus measures such as another side usefulness supersonic thickness meter, eddy current thickness meters in the one side of glass.Above method measuring process complexity, the instrument cost height, and be not suitable for on-line monitoring on the glass production streamline.

The utility model content

The utility model purpose be to provide a kind of simple in structure, measure convenient, as to be fit to on-line monitoring thickness of glass measuring instrument.

Scheme of the present utility model is: the thickness of glass measuring instrument, comprise scale and generating laser, it is characterized in that: a pedestal that is placed on the glass surface to be measured with planar base surface, have the printing opacity mouth on its bottom surface, a side of printing opacity mouth fixedly is equipped with the scale vertical with the bottom surface on pedestal, the opposite side that generating laser is fixed on printing opacity mouth on the pedestal is the opposite of scale, and laser that it sends and bottom surface are an angle.

The utility model has the advantages that: the laser oblique fire is on glass, the upper surface and the back side at glass produce two secondary reflections, reflected light is incident upon on the scale, the distance of two hot spots on the scale and the thickness of glass are directly proportional, on scale, indicate corresponding scale value, can read thickness of glass, have advantage simple in structure, easy to use, especially be suitable for the monitoring of line again of glass.

Description of drawings

The utility model is described in further detail according to embodiment and accompanying drawing below.

Accompanying drawing is a structural representation of the present utility model.

Mark among the figure: 1 scale, 2 light, 3 printing opacity mouths, 4 generating lasers, 5 pedestals, 6 glass.

Embodiment

Referring to accompanying drawing, embodiment has a pedestal 5 with planar base surface, in order to be placed on glass to be measured 6 surfaces, has the printing opacity mouth 3 of hollow out on its bottom surface.

A side of printing opacity mouth 3 fixedly is equipped with the scale vertical with the bottom surface 1 on pedestal, the opposite side that generating laser 4 is fixed on printing opacity mouth 3 on the pedestal is the opposite of scale 1, generating laser 4 is 45 ° of angles with the bottom surface, and the same and bottom surface of its laser that sends is 45 ° of angles.

Angle also can be selected other numerical value for use.

When pedestal 5 was placed on the glass 6, laser beam 2 passed the printing opacity mouth and projects on glassly, produces two secondary reflections at the upper surface and the back side of glass, and reflected light is incident upon on the scale 1.

Scale 1 subscript is shown with scale value, and above hot spot is that the flare on surface on glass is " 0 " scale, down indicates scale.

Because the distance of two hot spots on the scale and the thickness of glass are directly proportional, thereby, on scale, indicate corresponding scale value, can read thickness of glass.

Claims

1. thickness of glass measuring instrument, comprise scale (1) and generating laser (4), it is characterized in that: one is placed on the lip-deep pedestal (5) with planar base surface of glass to be measured (6), have printing opacity mouth (3) on its bottom surface, a side of printing opacity mouth (3) fixedly is equipped with the scale vertical with the bottom surface (1) on pedestal, the opposite side that generating laser (4) is fixed on printing opacity mouth (3) on the pedestal is the opposite of scale (1), and laser that it sends and bottom surface are an angle.
