A thin film thickness gauge

Abstract

The invention belongs to the technical field of thickness gauges, and particularly relates to a thin film thickness gauge. The thin film thickness gauge comprises a machine cover, a display screen, afirst protective plate, a second protective plate, a nameplate, rivets, hexagon socket bolts, function buttons, adjusting buttons, a telescopic rod, a pressure plate, a laser sensor, a first fixing mechanism, first sliding grooves, a second fixing mechanism, second sliding grooves, a supporting plate, a first sliding block, a first connecting plate, a supporting block, a second connecting plate, threaded holes, a third sliding groove, a pressing plate, reinforcing ribs, a screw rod, a driven wheel, a driving wheel, a motor, a first through groove and a second through groove. The two first sliding grooves are formed in the top of the base, and the two second sliding grooves are formed between the two first sliding grooves. By arranging the first fixing mechanism and the second fixing mechanism, the thin film thickness gauge can level thin film with lighter weight, and the phenomenon of large measurement data error caused by folds when the thin film is laid flat on the base is further avoided.

Description

technical field [0001] The invention belongs to the technical field of thickness gauges, in particular to a film thickness gauge. Background technique [0002] Thin film thickness gauge, also known as thickness gauge, film thickness detector, film thickness gauge, etc., the film thickness gauge is professionally suitable for various types of plastic films, sheets, diaphragms, papers, foils, silicon wafers, etc. The thickness of the material is accurately measured. The thickness gauge measures the thickness of the film by installing two laser sensors on the upper and lower sides of the measured object, and fixing the sensors on a stable bracket to ensure that the lasers of the two sensors are aligned at the same point. When the measured object moves, the sensor starts to sample its surface, and measures the distance between the upper and lower surfaces of the target and the upper and lower paired laser displacement sensors respectively. The measured value is transmitted to th...

Problems solved by technology

[0003] However, during the use of the current film thickness gauge, due to the light weight of the film, the film will usually wrinkle or fall with the wind on the chassis, which is inconvenient to fix the film, which will easily lead to large measurement errors. In view of this, The invention provides a film thickness gauge, which has the following characteristics:
