Embodiment 1

[0006] Example 1, a process for covering the surface of a resistance strain gauge. The corroded strain gauge is evenly pasted on a piece of glass, the position of the pad is covered with adhesive tape, and epoxy phenolic strain glue is applied to the surface of the strain gauge. , and then use the glue machine to shake the glue evenly, put it into the curing box, and use the temperature of 60 degrees for the first curing for 2.5 hours. After the first curing, use 2KG / CM 2 The pressure of the cover is pressed tightly, and then put into the curing box, and the second curing is carried out at a temperature of 180 degrees for 3 hours, and the thickness of the strain glue on the obtained resistance strain gauge is 0.15mm.

Embodiment 2

[0007] Example 2, a process for covering the surface of a resistance strain gauge. The corroded strain gauge is evenly pasted on a piece of glass, the position of the pad is covered with adhesive tape, and epoxy phenolic strain glue is applied to the surface of the strain gauge. , and then use the glue machine to shake the glue evenly, put it into the curing box, and use the temperature of 80 degrees for the first curing for 2 hours. After the first curing, use 3KG / CM 2 The pressure of the cover is pressed tightly, and then put into the curing box, and the second curing is carried out at a temperature of 170 degrees for 2.5 hours, and the thickness of the strain glue on the obtained resistance strain gauge is 0.1mm.

Embodiment 3

[0008] Example 3, a process for covering the surface of a resistance strain gauge. The corroded strain gauge is evenly pasted on a piece of glass, the position of the pad is covered with adhesive tape, and epoxy phenolic strain glue is applied to the surface of the strain gauge. , and then use the glue machine to shake the glue evenly, put it into the curing box, and use the temperature of 70 degrees for the first curing for 1.5 hours. After the first curing, use 2.5KG / CM 2 The pressure of the cover is pressed tightly, and then put into the curing box, and the second curing is carried out at a temperature of 175 degrees for 3.5 hours, and the thickness of the strain glue on the obtained resistance strain gauge is 0.12mm.

Abstract

A finishing layer technique applied to an electric resistance strain gauge belongs to the technology field of the sensor component manufacture. The technique comprises the steps as follows: pasting a piece of glass with the corroded strain gauge; covering the position of a bonding pad with an adhesive tape; applying the epoxy phenolic strain adhesive to the surface of the strain gauge; uniformly whirl-coating the adhesive by a whirl coating device; and solidifying, pressurizing to press out the finishing layer and solidifying again, thereby ensuring that the strain adhesive are the electric resistance strain gauge are in a tight connection. The strain gauge is protected, and the thickness of the strain adhesive is effectively controlled without influencing the good resistance variation performance of the strain gauge.

Description

technical field [0001] The invention relates to a covering process of a resistance strain gauge, and belongs to the technical field of sensor component manufacturing. Background technique [0002] At present, the resistance strain gauges for high-precision measurement are made of constantan alloy with a thickness of no more than 0.005mm, one side is coated with strain glue (the function is to insulate and transmit force changes), and it is made by photolithography, corrosion and other processes, and then Paste the film on the strain gauge to protect the strain gauge. Since the thickness of the cover surface of the film commonly used in the market is 0.25-0.35mm, the size is too thick, which leads to the decrease of the force conduction performance of the strain gauge. Accuracy also drops. Contents of the invention [0003] The purpose of the present invention is to overcome the problem of thicker dimensions caused by directly sticking the cover surface with the adhesive f...
