Embodiment Construction

[0030] The present invention is further described below in conjunction with accompanying drawing:

[0031] see Figure 1 to Figure 3 , the present invention is a resistance strain gauge automatic resistance measuring machine, such as figure 1 with figure 2 As shown, the automatic resistance measuring machine frame 1 is included, the base part of the rotary disk 9 is connected with the automatic resistance measuring machine frame 1 through screws, and the rotary disk 9 can be driven by a servo motor to realize free rotation. Four resistance-measuring stations are evenly distributed on the rotary table 9, and there is a material tray 8 above each station, and a communication valve island 10 is distributed below the station. By controlling the communication valve island 10, the negative pressure of the corresponding tray 8 can be controlled on and off to absorb or release the strain gauge. The electric slip ring is located at the center of the rotary disc 9, so that when the r...

Abstract

The invention discloses an automatic resistance measuring device for a strain gauge and an operation method. The automatic resistance measuring device comprises a rack, a rotary disc, material discs, a Y-axis movement unit, a Z-axis movement unit and a resistance measuring head, wherein the rotary disc is arranged on the rack, and a plurality of material discs are arranged on the rotary disc; and the Y-axis movement unit is arranged on the machine frame, the Z-axis movement unit is arranged on the Y-axis movement unit, the resistance measuring head is arranged on the Z-axis movement unit, and after the rotary disc rotates, the material discs are located below the resistance measuring head. The stability of the resistance measuring process is controlled by controlling the pressing depth of the probe, the rotating angle of the rotating disc, the negative pressure adsorption force and other parameters, the automatic resistance measuring function is achieved, and the automatic resistance measuring device has great advantages in the aspect of achieving batch and automatic operation. Meanwhile, a high-precision calibration plate greatly improves the measurement accuracy.

Description

technical field [0001] The invention belongs to the field of resistance strain gauge production, in particular to a strain gauge automatic resistance measuring device and an operation method. Background technique [0002] Resistive strain gauge (hereinafter referred to as strain gauge) is a sensitive element that utilizes the principle of "resistance-strain" and is the core component of a force sensor. The strain gauge is pasted on the surface of the elastic body. When the elastic body is subjected to external force, it will produce a slight deformation, which will cause the deformation of the strain gauge sensitive grid. After the deformation of the sensitive grid, the resistance will change accordingly. By measuring the change of the strain gauge resistance , the magnitude of the external force can be calculated. In the production process of the strain gauge, whether the strain gauge is qualified or not is judged by the resistance value. Therefore, the resistance measure...
