Abstract

The utility model discloses a measure the straightness's that hangs down of matte product device aims at providing a simple structure, easily installation, easy and simple to handle, a device of safe handling. The light source, the right angle leaning body and the CCD are fixed on the bottom plate, the centers of all the parts are on the same horizontal line, the baffle can slide up and down on the edge of the right angle leaning body and is used for shielding light which does not pass through a product, and the CCD is provided with analysis software and can automatically analyze the image edge. The utility model discloses a through the light that the slit that the CCD gathered between by the body and the product through the right angle spills, the analysis product draws the product straightness that hangs down with the angle that the right angle leaned on the body.

Description

Device for measuring verticality of rough surface product

Technical Field

The utility model belongs to the optical detection field specifically is a measure device that squareness falls of matte product.

Background

Optical products often have the straightness requirement that hangs down, to the straightness that hangs down of polished surface, can directly test with the contrast goniometer, and the straightness that hangs down of hair side is because the product is not reflective, and difficult precision measurement, and present main test mode is image projector test, paster test and omnipotent angle chi test. The image projector is difficult to measure the verticality of the wafer or the thin wedge angle sheet; the patch testing precision is low, and the repeatability is poor; the universal angle ruler is difficult to measure for wafers and small-sized products. There is a need for a simple result that can conveniently measure the perpendicularity of the matte in various shapes and sizes.

Disclosure of Invention

The utility model aims to solve the technical problem that a device for measuring the verticality of a matte product is provided.

The utility model discloses a measure hair side product straightness device that hangs down, lean on body, CCD including light source, baffle, right angle, light source, right angle lean on the body, CCD fixes on the bottom plate, fix on the bottom surface according to the horizontal direction in proper order, each parts central point puts on same water flat line, the right angle lean on the body side fluted, the baffle be L type slide, L type minor face card is leaned on the body recess like the right angle in, can slide from top to bottom.

The device for measuring the verticality of the rough surface product is characterized in that the light source is received by a CCD (charge coupled device) after passing through a slit formed by the product and the right-angle leaning body, the CCD collects a light transmission part for angle analysis, and the baffle plate needs to block redundant light.

The utility model has the advantages that: the product size is square or circular, the measurement can be carried out, the operation is simple, practical and convenient, the product cannot be damaged, and the device is simple in structure and easy to build.

[ description of the drawings ]

FIG. 1 is a schematic view of the product placement of the device of the present invention;

fig. 2 is a schematic structural diagram of the device of the present invention.

[ detailed description ] embodiments

The invention will be further described with reference to the following examples with reference to the accompanying drawings.

As shown in figure 2, the device for measuring the verticality of the matte product comprises a light source 1, a baffle 2, a right-angle leaning body 3 and a CCD4, wherein the light source 1, the right-angle leaning body 3 and the CCD4 are sequentially fixed on the bottom surface in the horizontal direction, and the centers of all the components are on the same horizontal line.

The light source 1 is parallel light. The tail part of the baffle 2 is provided with an L-shaped clamping groove which is matched with the groove of the right angle leaning body 3 and can slide up and down.

During the concrete implementation, according to the required measuring straightness that hangs down of the product that awaits measuring, place the product standard face on 90 right angles lean on body 3 bottom surfaces, closely laminate, the test face is relative with the vertical face of right angle lean on body 3, the product crest line that awaits measuring leans on body 90 crest lines near the right angle, according to the height of product, moving baffle 2 blocks the light leak position above the product, as shown in figure 1, after the parallel light incidence, baffle 2 and product shelter from invalid light, valid light sees through the product and leans on body slit with the right angle, form triangle-shaped or trapezoidal facula, CCD4 receives the facula, software analysis facula shape and angle, thereby obtain the product and lean on the contained angle that body 3 formed with the right angle, regard this contained angle as the product straightness that hangs down.

Claims (3)

1. The utility model provides a measure the straightness's that hangs down of matte product device, includes that light source, baffle right angle lean on the body and CCD to constitute, its characterized in that: the light source, the right-angle leaning body and the CCD are sequentially fixed on a datum plane in the horizontal direction, the centers of all the parts are on the same horizontal line, and the baffle can abut against the right-angle leaning body and slide up and down in the groove.

2. The apparatus of claim 1, wherein: the light source (1) is parallel light.

3. The apparatus of claim 1, wherein: the precision of the right-angle leaning body (3) is less than or equal to 5', and grooves are formed in the side surfaces.
