Abstract

The invention discloses a cover layer seal film for a strain gauge, and a production method and a using method thereof. The cover layer seal film comprises a strain gauge cover layer, the seal layer surface of the strain gauge cover layer is provided with an adhesive layer, and the adhesive layer is adhered with cover layer release paper, wherein the strain gauge cover layer is provided with a plurality of marking points, and positions, corresponding to strain gauge bonding pads, of the strain gauge cover layer, are hollow-out; and the cover layer seal film is used for sealing the whole straingauge. The cover layer seal film can realize the automatic sealing of the whole gauge strain, especially special-shaped pattern sealing which cannot be realized through a conventional technology, allows the alignment precision to be 3 times higher than that the manual alignment precision, improves the sealing efficiency by 5 times or more, and completely solves the problems of low efficiency, unstable quality and poor product consistence of existing artificial production.

Description

technical field

[0001] The invention relates to the technical field of strain gauge sealing, in particular to a cover layer sealing film for a strain gauge, a preparation method and a use method thereof. Background technique

[0002] The sealing of the strain gauge cover layer is one of the core processes in the production process of the strain gauge. On the one hand, the cover layer can play an insulating role, and on the other hand, it can effectively protect the sensitive grid of the strain gauge from mechanical damage, which will cause the strain gauge to be unusable.

[0003] At present, the main method of sealing the strain gauge is to prepare a large sealing film first, cut the sealing film into strips, manually apply glue to the strip sealing film, and then seal the coated strip with the help of light source, positioning marks, and auxiliary tools. The membrane is bonded to the strain gauges to form a seal.

[0004] In this method, before the worker seals the strain...
