Description

Gloss meter

The utility model relates to a kind of Grossmeters that is applicable to metal and non-metal material surface glossiness feature measurement.

The Grossmeters of present domestic use, basically all be single angle measurement system, can not be suitable for the measurement of glossiness characteristic of the body surface of various luster characteristic, often need to be equipped with the Grossmeters of multiple different angles, just can finish measurement, inefficiency to object glossiness characteristic.The Grossmeters of single in addition angle system exists also that volume is big, unreasonable, the cost problem of higher of device layout.

The purpose of this utility model is to provide a kind of employing international optical measurement standard, can increase work efficiency, reduces production cost, volume is small and exquisite, low-cost Grossmeters.

Grossmeters described in the utility model, adopt light reflection principle, with refractive index Nd(for example 1.567) welding glass under the state of table plane polishing, only natural light beam is reflected by this table plane, its reflectivity is defined as 100 gloss, the center line of incident beam should become certain angle of inclination E with the perpendicular line on tested object table plane, to finish the measurement to tested object glossiness.This angle of inclination E can be divided into 20 °, 45 °, 60 °, 75 °, 85 ° according to the gloss characteristic of tested object.When the incident light velocity of certain angle E shines tested object and after this object surfaces reflection is received lens and receives by diversing lens, pass to photoelectric sensor again and be converted to electric signal by it, after this electric signal is transfused to the processing of data amplification computing display circuit, just can directly read the glossiness performance data of tested object by data display equipment.

The optical measurement probe group of Grossmeters described in the utility model is mounted on one 180 ° the semicircular gage probe block, this gage probe block is fixed on the measurement base that an and arranged on left and right sides partly is thinner than center section, for ease of various devices are installed, there is a rearmounted plate to be connected with the measurement base.Be fixed in the optical measurement probe group gloss characteristic different on the gage probe block, can be divided into the optical measurement probe group of 60 °, 20 °, 60 °, 85 °, 20 °, 45 °, 75 ° three groups of different angles according to tested object.Be provided with the rectification charging road in the circuit of data amplification computing display circuit part, mu balanced circuit, ac-dc converter circuit, automatic balancing circuit amplifies computing circuit, under-voltage indication sample circuit and booster circuit and data display circuit.Optical measurement probe group and data amplify computing display circuit part by shielded cable be connected, transmission signals.The circuit parameter of the optical measurement probe group of three groups of different angles is slightly different, but its structure is identical.

Below in conjunction with drawings and Examples Grossmeters described in the utility model is described in further detail.

Grossmeters described in the utility model is by emission diaphragm (1), receive diaphragm (2), diversing lens (3), receiver lens (4), color filter (5), frosted glass (6), photoelectric sensor (7), the optical measurement probe group (A) that luminous original paper (8) is formed, data are amplified computing display circuit part and gage probe block (9), measure base (10), rearmounted plate (11) etc. are formed.This Grossmeters is when work, rectifier charging circuit carries out rectification with AC power, the luminous original paper (8) that has little condenser by one group of power supply supply of mu balanced circuit (2) output top sends irradiation light, light is by behind the color filter (5), be corrected for the former or approximate incident function of C light correction light source (D65 light source), this light source shines on the tested object surfaces through diversing lens (3) by emission diaphragm (1) again, after tested object surfaces reflects illumination beam, received by the receiver lens (4) identical with diversing lens (3) angle, and be converted to electric signal by photoelectric sensor (7) by receiving diaphragm (2) and frosted glass (6), this signal just can read the glossiness data of tested object from display after data are amplified the processing of computing display circuit.

The diversing lens (3) and the receiver lens (4) of Grossmeters optical measurement probe group described in the utility model (A) are the plano-convex lens of double-sided coating, its bore is 5-35mm, focal length is 20-50mm, it is 80-120mm that optical measurement probe group (A) is fixed in an internal diameter, external diameter is that the 100-160mm cambered surface is wide on 180 ° the semicircle gage probe block (9) of 20-60mm, gage probe block (9) is fixed in to be measured on the base (10), this measures the thick 6-15mm of base (10), the centre has rectangular measurement mouth, for reducing surface of contact, improve measuring accuracy, measure the left side, bottom surface of base (10), right both sides respectively account for total floorage four/part than the thin 0.05-0.5mm of middle 2/4ths parts.For the ease of various devices are installed, there is a rearmounted plate (11) to be connected with measurement base (10).Because the glossiness characteristic of object being measured has nothing in common with each other, the incident beam in the probe of the last hard-wired measuring sonde group (A) of gage probe block (9) and the center line of folded light beam can become 20 ° respectively with the perpendicular line on tested object table plane, 45 °, 60 °, 75 °, 85 ° angle promptly can fixedly mount the optical measurement probe group (A) of 60 °, 20 °, 60 °, 85 °, 20 °, 45 °, 75 ° three groups of different angles respectively according to measuring needs on the gage probe block (9).When setting angle is 85 ° optical measurement probe group (A), measures the and arranged on left and right sides of the measurement mouth on base (10) surface and need open a dark 5.5-14.5mm, the groove of wide 20-60mm.

It partly is by rectifier charging circuit that the data of Grossmeters described in the utility model are amplified the computing display circuit, and mu balanced circuit amplifies computing circuit, data display circuit, and booster circuit, under-voltage indication and sample circuit are formed.Owing to for providing the rechargable power supplies charging for oneself, can carry out work by power autonomous power supply in power free test site by rectifier charging circuit.Photoelectric sensor (7) links to each other with the amplification computing circuit, by amplifying computing circuit electric signal is handled, and by data display circuit the glossiness data is shown again.In order to improve the precision of measurement, can amplify in data an automatic balancing circuit is set in the computing display circuit.Data amplify computing display circuit part can with 20 °, 45 °, 60 °, 75 °, 85 ° optical measurement probe group (A) interworking, and the AC and DC power supply is dual-purpose.Can adjust by button the selection of measuring light path system.
