Pasting device for foil gauge

Abstract

The invention discloses a pasting device for a foil gauge, wherein the pasting device is used for pasting a foil gauge on a paster area of a test piece surface. The pasting device comprises a housing (1); an elastic pressing plate (2) is fixed inside the housing; and the bottom of the elastic pressing plate (2) are used for connecting a foil gauge; besides, a drive element that is capable of reciprocating motions is also arranged inside the housing (1). On one hand, the drive element makes motions along a direction approaching the elastic pressing plate (2) to press the elastic pressing plate (2), so that the foil gauge that is connected to the bottom of the elastic pressing plate (2) is pasted at a paster area; and on the other hand, the drive element makes motions along a direction far away from the elastic pressing plate (2), so that the elastic pressing plate (2) is broken away from the foil gauge and is reset. According to the above-mentioned structural design of the device, on one hand, a pasting efficiency of a foil gauge is improved; and on the other hand, a pasting quality of the foil gauge is enhanced.

Description

technical field [0001] The invention relates to the technical field of strain gauge sticking, in particular to a strain gauge sticking device. Background technique [0002] In the field of strain gauges, the working principle of strain gauges is based on the strain effect, that is, when a conductor or semiconductor material is mechanically deformed under the action of an external force, its resistance value changes accordingly. This phenomenon is called "strain effect". During the test, the strain gauge is first pasted on the surface of the specimen, and then the specimen is deformed by an external force, and the strain gauge pasted on the surface of the specimen deforms accordingly, and then the strain is measured by measuring the change of the resistance value of the strain gauge . In the test process, it is an important step to paste the strain gauge on the surface of the test piece. [0003] At present, the pasting of strain gauges is mainly done manually, and there is...

Problems solved by technology

[0003] At present, the pasting of strain gauges is mainly carried out manually, and there is no convenient pasting tool available, so the efficiency is low

In addition, the sticking quality of the strain gauge mainly depends on the proficiency of the test personnel. When the strain gauge is manually pasted, the fingers are pressed unevenly, which may easily cause uneven thickness of the glue coating. At the same time, the strain gauge is also very easy to tilt and produce angle errors. These influencing factors will bring large errors to the strain test results.

[0004] In addition, the lower temperature will cause the stickiness of the pasting glue to fail. Therefore, under the condition of low temperature, it is more difficult to stick the strain gauge, and even if it can be pasted, it will not be firmly pasted.
