Embodiment Construction

[0029] In order to further understand the features of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. However, the accompanying drawings are provided for reference and illustration only, and are not intended to limit the protection scope of the present invention.

[0030] figure 1 It is a structural schematic diagram of the present invention. The present invention is composed of a cantilever 101 , a connecting piece 102 , a triangular star-shaped diaphragm 103 and a base plate 104 .

[0031] The triangular star diaphragm 103 has an inner ring 107 and an outer ring 108 . A hole 109 is provided between the inner ring 107 and the outer ring 108, so that when the inner ring 107 is subjected to a force, elastic relative deformation is likely to occur. (For detailed technical content, please refer to Figure 9 and Figure 10 )

[0032] The cantilever 101 is rigidly connected to the inner ring 107 of t...

Abstract

The invention discloses a static capacitive force-measuring sensor. The sensor comprises a cantilever, a connecting piece, a triangular star diaphragm and a substrate, wherein the connecting piece is bonded with the cantilever through viscose; the triangular star diaphragm is provided with an inner ring and an outer ring; the inner ring is connected with the connecting piece in a laser welding mode; the outer ring is fixedly connected with the substrate through a rivet; and one side of the substrate contacted with the triangular star diaphragm is provided with a first electrode and a second electrode, and the other side of the substrate is provided with a circuit.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a load cell. Background technique [0002] In textile equipment, the motor is used to drive the drum to rotate to wind the yarn. During the winding process, the stability of the motor speed and the mechanical transmission of the equipment all affect the tension of the yarn, so the tension on the yarn varies. [0003] The more stable the tensile force on the silk, the more stable the quality of the finished product. On the contrary, if the stretching force fluctuates, the finished product will not be smooth enough and the quality will be poor. For example, in the processing of chemical fiber and cotton spinning, the stretchability and softness of the silk have a great relationship with the stability of the equipment used to process the silk. [0004] Therefore, a device is needed to detect the magnitude of the tension on the wire. Contents of the invention [0005] The purpos...
