Wire winding method and device for wire winding type strainmeter

Abstract

The invention relates to a wire winding method and device for a wire winding type strainmeter. The device comprises a working platform, a linear movement system is fixed to the working platform, a mechanical arm is arranged on the linear movement system and makes reciprocating movement on the linear movement system, a glue containing and wire outgoing device is connected to the mechanical arm, an end wire outlet of the glue containing and wire outgoing device is arranged close to a rotation platform, a substrate film adheres to the rotation platform, a wire to be wound stretches out of the glue containing and wire outgoing device, and the end of the wire adheres to the substrate film. In the winding process, after the wire to be wound stretches out of the glue containing and wire outgoing device, the end of the wire is made to adhere to the substrate film of the rotation platform through glue, and the wire can be spirally wound through cooperation between linear movement of the mechanical arm and rotation movement of the rotation platform.

Description

technical field [0001] The invention relates to a technology for manufacturing a resistance strain gauge, in particular to a method and a device for winding a wire of a wire-wound strain gauge. Background technique [0002] With the development of sensor manufacturing technology, sensors have more and more demands on strain gauges with large range, large resistance value and even super large resistance value. At present, domestic strain gauge sensors generally use foil strain gauges made by photolithographic etching technology. Due to the limitations of materials and manufacturing processes, traditional foil strain gauges have a low pass rate in the production of large-scale and large-resistance strain gauges. Low utilization rates lead to high costs. At the same time, the resistance value of the foil strain gauge has a certain limit. When the required resistance value exceeds the limit of the foil material, it cannot be produced. [0003] At present, there are basically n...

Problems solved by technology

At present, domestic strain gauge sensors generally use foil strain gauges made by photolithographic etching technology. Due to the limitations of materials and manufacturing processes, traditional foil strain gauges have a low pass rate in the production of large-scale and large-resistance strain gauges. Low utilization, leading to high costs

At the same time, the resistance value of the foil strain gauge has a certain limit. When the required resistance value exceeds the limit of the foil material, it cannot be produced.

[0003] At present, there are basically no wire-wound strain gauges in China, and some foreign industry giants have a small number of products
