Description

Big array resistors formula foil gauge automatic detection, correction of the flank shape, method for separating
Present patent application is December 31 2015 applying date, application number 201511030159.9, innovation and creation name It is referred to as the divisional application of the application for a patent for invention of " big array resistors formula foil gauge automatic detection, correction of the flank shape, sorting unit and method ".
Technical field
The invention belongs to resistance strain plate production technical field is and in particular to a kind of big array resistors formula foil gauge is automatic Detection, correction of the flank shape, method for separating.
Background technology
Resistance strain plate be Analysis of Experimental Stress, test and measuring technology, automatic detection and control technology and weigh or The key element of force cell, has that size is little, creep is little, a good anti-fatigue performance and the features such as good stability, It is widely used in various machineries and engineering structure intensity and the diagnosis in life-span and assessment, be also used for detection and the meter of multiple physical quantitys Amount, realizes measurement and the control of production process and scientific experimentss process.Resistance strain plate is mainly pasted onto the surface of elastomer, The micro-strain (elongating or shortening) that elastomer produces on rear surface loaded, makes to be pasted onto the foil gauge on its surface also in company with product Change shape, and after resistance strain gage deformation, its resistance will change (increase or reduce), then through corresponding measuring circuit handle This resistance variations is converted to the signal of telecommunication (voltage or electric current) output, measures the change of resistance, you can calculate elastomer by formula The strain on surface, and corresponding stress.
As shown in figure 21, resistance strain plate is mainly made up of sensitive grid 41, substrate 42, cover layer 43 and lead 44, quick Sense grid 41 are bonded between substrate 42 and cover layer 43 with binding agent 45.In foil gauge production process, first foil is firmly glued It is attached in substrate 42, substrate 42 material is usually glued membrane (phenol-formaldehyde resin modified, polyimide resin, epoxy resin etc.), thickness It is about 0.02mm～0.04mm；Sensitive grid 41 material is about the metal alloy foil of 0.0025mm～0.005mm for thickness, and foil leads to It is often constantan foil, karma foil material, annealing constantan foil etc.；The molding of sensitive grid 41 is according to certain circuit requirement by foil Carry out photoetching, corrosion, the resistance wire finally remaining in substrate 42 is sensitive grid 41.Exist to improve sensitive grid 41 further Job stability during use and service life are in addition it is also necessary to increase cover layer 43, general cover layer 43 on sensitive grid 41 Material identical with base material, thickness is about 0.01mm～0.02mm, the gross thickness of resistance strain plate be about 0.035mm～ 0.05mm.
Resistance strain plate is to lose according to certain queueing discipline figure on the metal foil plate of a 102mm × 115mm Quarter forms, and a metal foil plate generally has the figure of multiple products.Have on a kind of big array resistors formula foil gauge diaphragm Multiple resistance strain plate units by array arrangement, each resistance strain plate unit draws 4 electrodes, measures as 4 Point.
Need to separate single strain flake products from justifying in the foil gauge production later stage, and to single strain Flake products are detected, are sorted finally according to testing result, need defeated to its Static Electro resistance, magnitude of voltage, sensitivity, heat Go out, transverse sensitivity ratio, creep, the multinomial operating characteristic such as strain limit and fatigue life are tested.Wherein Static Electro resistance, Magnitude of voltage, sensitivity technique belong to one hundred percent inspection, and other performance index belong to bulk sampling inspection.At present, correction of the flank shape is manually to make Single product is pruned along the outer rim of product with shears, this method not only low production efficiency, labor strength Greatly, and prune that dimensional accuracy is low, there is larger fluctuation in the overall dimensions of same batch products, be unfavorable for steady to product quality Fixed control；Manual testing is completely dependent on to the resistance of foil gauge, voltage measurement, because foil gauge yield is big, the workman of needs is many, Cause high labor intensive, production cost is high, and testing efficiency is low, easily malfunction, be also unfavorable for the stability to product quality Control；And, sorting is also artificial separation, artificial separation method not only low production efficiency, and labor strength is big, production cost Height, and easily malfunction, also it is unfavorable for the stability control to product quality.
