Description

Technical Field

[0001] This utility model belongs to the field of multi-dimensional force sensor strain gauge positioning equipment, specifically a robot multi-dimensional force sensor strain gauge positioning device. Background Technology

[0002] A strain gauge is a sensor that converts mechanical strain into an electrical signal. It is usually made of resistive material. When a strain gauge is subjected to an external force, its resistance value changes. This change can be converted into an electrical signal through a circuit, thereby realizing the measurement of the external force. In multi-dimensional force sensors, strain gauges are usually attached to an elastic element. When an external force is applied to the elastic element, the elastic element will deform. This deformation will be captured by the strain gauge and converted into an electrical signal. In the manufacturing process of multi-dimensional force sensors, the positioning and attachment of strain gauges is a very critical step. In order to ensure the measurement accuracy and stability of the sensor, a special strain gauge positioning device is usually required.

[0003] According to Chinese Patent Application No. 202223393037.4, a strain gauge bonding and positioning device for stress testing is disclosed, belonging to the field of stress testing technology. It includes a quadrilateral frame structure composed of four positioning blocks. Adjacent positioning blocks are connected by a first telescopic rod. Suction cups are installed at the bottom of the positioning blocks. A plastic film rewind box is installed on the first telescopic rod. A second telescopic rod is hinged to the top of one of the positioning blocks. A connecting plate is installed at the other end of the second telescopic rod. A cross positioning rod is installed on the top of the connecting plate. A connecting shaft is installed at the bottom of the connecting plate. A connecting turntable rotates on the connecting shaft. An adjusting rod and a lever are installed on the turntable. The position of the strain gauge is quickly adjusted and aligned using the lever and adjusting rod, ensuring that the strain gauge is not skewed and is accurately bonded to the surface of the object being measured, resulting in more accurate measurement data. The device integrates positioning, adjustment, and film laying into a single unit, making it convenient to use, saving time, and improving work efficiency.

[0004] Existing technology effectively solves the problem of deviation that easily occurs during the bonding process of strain gauges and has the effect of positioning strain gauges. However, this positioning device adjusts the position by means of a telescopic rod, and the accuracy of the telescopic rod is low, resulting in low positioning accuracy of strain gauges.
