Button-type five-dimensional force sensor

Abstract

The invention discloses a button-type five-dimensional force sensor which comprises a cylindrical base, wherein a base plate is arranged in the cylindrical base; a circular covering plate is arranged at the upper end of the cylindrical base; a junction circuit board is arranged at the lower end of the cylindrical base; a handle is arranged at one side of the junction circuit board; an outgoing line encapsulation head is arranged at one side of the cylindrical base; one side of the outgoing line encapsulation head is adhered to a side wall of the cylindrical base; the bottom of the outgoing line encapsulation head is fixed on the handle of the junction circuit board; six strain gauges are respectively adhered to the upper and lower end faces of the base plate; and terminals of the strain gauges are all welded on the junction circuit board and subsequently led into the outgoing line encapsulation head together. By adopting a double-end circular membrane sheet structure, design height of the sensor can be reduced greatly, and at the same time, height of the sensor is further reduced by adopting a novel machining process; for material selection, a group bridge is designed by adopting ultra-small strain gauges, so that diameter is reduced greatly; and by adopting a mode of an outgoing line of the junction circuit board, the height is not increased, and at the same time, signal lines are reliably led out.

Description

technical field [0001] The invention mainly relates to the field of sensors, in particular to a button-type five-dimensional force / torque sensor. Background technique [0002] Most of the existing five-dimensional force / torque sensors are designed and manufactured for engineering measurement, precision control, precision manufacturing and other fields, and there are no products specially designed for the measurement of small areas such as the sole of the foot or the hand; these five-dimensional force / torque sensors Torque sensors cannot be directly applied to microscopic measurement analysis. The main reasons are as follows: [0003] 1. The diameter of most sensors is too large and the height is too high to be installed inside the sole; [0004] 2. Most of the existing sensor acquisition modules cannot satisfy multiple (greater than or equal to 4) sensors for real-time synchronous acquisition and maintain the sampling frequency of each dimension. [0005] 3. The gener...

AI Technical Summary

Problems solved by technology

[0003] 1. The diameter of most sensors is too large and the height is too high to be installed inside the sole;

[0004] 2. Most of the existing sensor acquisition modules cannot meet the real-time synchronous acquisition of multiple (greater than or equal to 4) sensors and maintain the sampling frequency of each dimension

[0005] 3. The general sensor cannot make the circuit board and the sole contact, so that the circuit board can be used as a test board or a support surface

[0006] 4. The traditional foot contact is basically point contact, not surface contact, which cannot effectively measure the force in three directions of space
