Embodiment 1

[0033] like Figure 1-3 As shown in the figure, the embodiment of the present invention provides a welding strain gauge curing device, including a welding strain gauge clamping template and a pressure pedestal. Rotating around the axis, it is very convenient to open and close, so that the lower bottom plate 1 and the upper top plate 2 fit tightly when they are attached. The size of 4 is consistent with the size of the welding strain gauge 11, and grooves 4 of different sizes and shapes can be engraved on the same lower bottom plate 1. The groove 4 is processed by the engraving process, and the welding strain gauge 11 is placed inside the groove 4. , the welding strain gauge 11 includes a thin stainless steel substrate 5, a resistance strain gauge sensing element 6, and the resistance strain gauge sensing element 6 is fixed and connected to the thin stainless steel substrate 5 by a long-term high-performance two-component epoxy resin adhesive H-610 , the upper surface of the w...

[0036] The key to the pressure curing process is the reasonable control of pressure, temperature and time.

[0037] The welding strain gage curing process includes the following steps:

[0038] S1. Placement

[0039] Paste the resistance strain gauge sensing element 6 on the thin stainless steel substrate 5, place the preliminarily bonded thin stainless steel substrate 5 and the resistance strain gauge sensing element 6 in the groove 4, and place a layer of polytetrafluoroethylene on the top. Film 7, then install the plastic groove substrate 8, and attach the lower bottom plate 1 and the upper top plate 2, and place them on the U-shaped platform 9;

[0040] S2. Perform initial solidification

[0041] By rotating the pressurizing threaded rod 10, the pressure is increased to make the pressure reach 0.1-0.3MPa, and then the device is put into a temperature box, the temperature is 120 ° C, and the temperature is kept for two hours;

[0042] S3. Subsequent processing

According to the instrument and the process, the bottleneck link in the manufacturing of the welding strain gauge is solved, the specification and standardization of the production process of the welding strain gauge are favorably improved, the quality of the welding strain gauge and the measurement performance during application are improved, and the wide application of the welding strain gauge is promoted.

Description

technical field [0001] The invention relates to the technical field of sensor processing, in particular to a welding strain gauge curing device and process. Background technique [0002] Welded strain gauges are essentially a resistance strain gauge. Traditional resistance strain gauges are pasted on a thin stainless steel substrate of suitable size, so that the strain gauge has the characteristics of welding. Steel beams, steel columns, steel truss members and metal machines, etc. Welded strain gauges have the same temperature performance self-compensation and consistency as ordinary resistance strain gauges. Compared with ordinary resistance strain gauges, they have the disadvantages of cumbersome process, low efficiency, and limited by the construction site environment. They have spot welding installation. The advantages of flexible layout of instant welding and measuring, and the protection and fixing of the lead wires are carried out to ensure that the lead wires are f...
