Abstract
The utility model discloses a laser thickness-measuring device, which comprises a measuring mechanism and a servo motor, wherein the measuring mechanism is arranged across a tape threading mechanism, the measuring mechanism mainly comprises two laser transmitters and a receiver, the tape threading mechanism allows a measured object to pass through the measuring mechanism for thickness measurement; and the servo motor is connected with the measuring mechanism, thus the measuring mechanism can do rectilinear motion on a guide rail, so as to measure the thicknesses of different points of the measured object. An optical path is formed by the two laser transmitters and the receiver, and inaccurate measured value cannot be caused by vibration of the measured object.
Description
Technical field
The utility model relates to a kind of linear dimension measuring device, is specifically related to a kind of measurer for thickness of laser single collector.
Background technology
Now the industrial surveying instrument that is used for measuring the material thicknesses such as battery pole piece, coiled material generally all uses the thickness measurement with laser instrument, and it is contactless that laser measurement method belongs to, can on-line measurement, and real-time performance is good, uses very extensive.
Present thickness measurement with laser instrument adopts is two double light path laser trigonometries that independent light path forms up and down, but in this double light path laser trigonometry thickness measuring system up and down two independently measuring system be difficult to synchronously so that the measured object vibration has limited the further raising of this thickness measuring method precision on the impact of measurement.
The utility model content
The utility model purpose is: a kind of less laser thickness measuring instrument of testee vibration effect that is subjected to is provided.
The technical solution of the utility model is: a kind of laser thickness measuring apparatus comprises measuring mechanism and Tape threading apparatus, and measuring mechanism is located at Tape threading apparatus; Measuring mechanism comprises the support that is the C type, and the opening two ends of described support are equiped with two generating lasers, and the blind end of described support is equiped with receiver.
Preferably, described support is arranged on the guide rail, and is connected with servomotor.
Preferably, described receiver comprises from the blind end of described support and sets gradually coaxial CCD, imaging len, glass sheet and aperture diaphragm.
Preferably, described Tape threading apparatus comprises a plurality of guide rollers, two ends, the axle center hinged support frame of described guide roller, and the both sides of described guide roller are respectively equipped with drawing mechanism and material collecting device.
Preferably, the emission light path coaxial of described generating laser.
The utility model has the advantages that: the light path system that two generating lasers and receiver form, when testee vibrates, CCD can obtain the reflected light of testee upper and lower surface simultaneously, processes, and can not cause because of the vibration of testee the out of true of data; And servomotor can be controlled support and do rectilinear motion at guide rail, measures the thickness of difference, makes data have diversity, comparability.

Embodiment
Embodiment:
In conjunction with shown in Figure 2, the opening two ends that are the support 1 of C type are equiped with generating laser 2 by Fig. 1, the emission light path coaxial of generating laser 2, and the blind end of support 1 is equiped with receiver 3, and support 1 is arranged on the guide rail 4, and is connected with servomotor 5; Receiver 3 comprises from the blind end of support 1 and sets gradually coaxial CCD31, imaging len 32, glass sheet 33 and aperture diaphragm 34; Two guide rollers 61 are built up in respectively the both sides of support 1, and two ends, the axle center hinged support frame 62 of guide roller 61, testee 9, are collected by material collecting device 8 through guide roller 61 by drawing mechanism 7 dischargings.
The light path system that two generating lasers 2 and receiver 3 form can not cause because of the vibration of testee 9 out of true of measuring numerical value; Servomotor 5 can be controlled support 1 and do rectilinear motion at guide rail 4, measures the thickness of difference, makes data have diversity, comparability.
Fig. 3 is the perfect optical system imaging schematic diagram of aid illustration measure thickness principle of the present invention.To be set as reference planes through the optical axis of imaging len 32 and the plane vertical with the CCD31 light-sensitive surface, it is two objects of △ h1 and △ h2 that the hot spot of testee 9 upper and lower surfaces can be considered as respectively with respect to reference planes above and below height, image height in imaging len 32 rear imagings is respectively h1 and h2, by geometrical optics knowledge as can be known: h1=β Δ h1, h2=β Δ h2, so have: (h1+h2)=β (Δ h1+ Δ h2), β is the vertical axle magnification of imaging len 32 in the formula, (△ h1+ △ h2) is the actual (real) thickness of measured object, (h1+h2) is the distance when upper two hot spots of CCD31.Can calculate through computing machine by the hot spot spacing after system demarcated and obtain the measured object detect thickness.
Those skilled in the art will readily understand; the above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
