Abstract

The invention belongs to auxiliary tools of optical measurement instruments and particularly relates to a contourgraph optical gate. The contourgraph optical gate includes a substrate. The substrate is provided with a door opening allowing emergent light and incident light of a contourgraph to pass. The substrate is further provided with a gate plate parallel to the surface of the substrate. The gate plate is arranged on the substrate and reciprocates in the direction parallel to the substrate. The door opening is located on the motion path of the gate plate. When the contourgraph is in a working state, the gate plate is opened, light beams can penetrate through the optical gate smoothly; when the contourgraph does not work, the gate plate is closed, so optical assemblies of the contourgraph are prevented from being contaminated by dust, moisture and other substances. Accordingly, the contamination resistance capability of the contourgraph is greatly improved, and the service life of the contourgraph is greatly prolonged.

Description

Contourgraph optical gate

Technical field

The invention belongs to the auxiliary mould of optical measuring instrument, be specifically related to a kind of contourgraph optical gate.

Background technology

Contourgraph is the equipment utilizing optical principle to measure object section profile, its cardinal principle is the surface adopting line source to irradiate object under test, then the light profile on object under test surface is gathered by image acquisition units, and then determine the cross section profile of object, therefore contourgraph generally comprises bright dipping and light inlet two minute surfaces.In Steel-rolling Industry, contourgraph is usually used in the overall size of the red steel of on-line checkingi, but on-line checkingi operating mode is general relatively more severe, and site environment high temperature, high humidity, very easily cause damage to the optical module of contourgraph.

Summary of the invention

The object of this invention is to provide a kind of can protect profile instrument optical module by the rugged surroundings such as high temperature, high humidity infringement contourgraph optical gate.

For achieving the above object, the invention provides following technical scheme: a kind of contourgraph optical gate, comprise substrate, described substrate is provided with the door opening passed through for contourgraph emergent light and/or incident light, described substrate is also provided with the flashboard parallel with this substrate surface, described flashboard is along being parallel to the direction of substrate toward moving setting on substrate, and described door opening is positioned on the motion path of flashboard.

Technique effect of the present invention is: when contourgraph is in running order, and flashboard is opened, and light beam can pass through optical gate, when contourgraph does not work, flashboard cuts out, and avoids the optical module of the Substances Pollution such as dust, aqueous vapor contourgraph, substantially increases the serviceable life of contourgraph.

Accompanying drawing explanation

Fig. 2 is rear view of the present invention, and in figure, flashboard is in opening;

Fig. 3 is rear view of the present invention, and in figure, flashboard is in closed condition.

Embodiment

As shown in Figure 1, a kind of contourgraph optical gate, comprise substrate 10, described substrate 10 is provided with door opening 11a, 11b of passing through for contourgraph emergent light and incident light, described substrate 10 is also provided with the flashboard 20 parallel with this substrate 10 plate face, described flashboard 20 is along being parallel to the direction of substrate 10 toward moving setting on substrate, and described door opening 11a, 11b are positioned on the motion path of flashboard 20.When contourgraph is in running order, flashboard 20 is opened, and light beam can pass through optical gate, and when contourgraph does not work, flashboard 20 cuts out, and avoids the optical module of the Substances Pollution such as dust, aqueous vapor contourgraph, substantially increases the serviceable life of contourgraph

As shown in Figure 1, 2, 3, side plate face opposing with door opening 11a, 11b on described flashboard 20 is provided with the wiper unit for wiping contourgraph minute surface, is fixedly connected with between described wiper unit with flashboard 20 for detachable.

Further, described wiper unit comprises two slat gum rub piece 21a, 21b, when two slat gum rub piece 21a, 21b slide with flashboard 20 respectively the wide instrument of trailing wheel go out light microscopic and enter the minute surface of light microscopic inswept, the length direction of described rubber rub piece 21a, 21b is vertical with flashboard 20 glide direction or arrange in being similar to vertical angle.

Further, described rubber rub piece 21a, 21b are separately fixed on clamp 23a, 23b, described clamp 23a, 23b are provided with hanging hole, described hanging hole and flashboard 20 is arranged first is linked up with and is matched, the upper one end away from hanging hole of clamp 23a, 23b is provided with the second hook, and described second hook is locked by the hasp 24 that flashboard 20 is arranged.

In the process that flashboard 20 cuts out or opens, rubber rub piece 21a, 21b the entering light microscopic and go out the minute surface of light microscopic of inswept contourgraph respectively, the floating dust of lens surface is cleaned, cleaning of further guarantee contourgraph optical component surface, in addition, because rubber rub piece 21a, 21b need often to change, therefore rubber rub piece 21a of the present invention, 21b are arranged to Demountable, only need stir the dismounting that hasp 24a, 24b easily can realize rubber rub piece 21a, 21b.
