Description

Technical Field

[0001] The utility model relates to the technical field of force sensor systems, in particular to a novel force sensor system with a positioning function. Background Art

[0002] A force sensor is a device used to measure the force applied by an object. It can convert the force applied by the object into an electrical signal, thereby achieving force measurement and monitoring. Force sensors are widely used in various fields and can help monitor and control the size and direction of the force of an object, thereby achieving precise control and monitoring. The types and working principles of force sensors vary.

[0003] Most traditional force sensors have unstable supports, uneven force, and are unable to measure the placement of objects. Therefore, the utility model provides a novel force sensor system with a positioning function to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a new force sensor system with a positioning function. Each sensor can work independently, so as to capture the force changes at different positions on the surface of the object, which is helpful to have a deeper understanding of the force state of the object. Moreover, the four force sensor mechanisms can be flexibly arranged in different positions to adapt to objects of different shapes and sizes. This flexibility makes the system more versatile and can be applied to a variety of scenarios.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new force sensor system with positioning function, comprising four force sensor mechanisms, sensors and control circuit boards, a placement plate is arranged between the upper end surfaces of the four force sensor mechanisms, and a display screen is embedded in a position close to one side of the rear side of the upper end surface of the placement plate;

[0006] The sensor is connected to an input unit, and the control panel is connected to an input and output device;

[0007] Through the above technical solution, using four identical high-precision force sensor mechanisms, the accuracy and reliability of the measurement results can be ensured. The four force sensor mechanisms can work simultaneously and can be calibrated and compensated with each other. If one sensor fails or has an error, the other sensors can provide redundant information to enhance the stability and reliability of the entire system.

[0008] Further, the four force sensor mechanisms include four force sensor bodies, the upper end surfaces of the four force sensors are fixedly provided with pressure heads, and the lower end surfaces of the four force sensors are fixedly provided with friction pads;

[0009] Through the above technical solution, the friction pad under the force sensor body allows it to stand more stably and avoid slipping, and the pressure head above it allows the received pressure to be more accurate.

[0010] Further, the control circuit board is connected with an output unit, a power supply unit and a signal voltage conversion unit;

[0011] Through the above technical solution, the output unit, the power supply unit and the voltage conversion unit can be controlled separately through the control circuit, making the system more convenient to use.

[0012] Furthermore, the input and output device is provided with a host computer, and the input unit is connected to the control circuit board;

[0013] Through the above technical solution, the signal is transmitted to the input and output device through the host computer, and the signal can be transmitted to the control circuit board through the input and output device.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model proposes a new force sensor system with positioning function. Four force sensor mechanisms can monitor four different force channels at the same time to obtain more information data. This multi-point monitoring can increase the accuracy and reliability of positioning and reduce errors. Each sensor can work independently, so as to capture the force changes at different positions on the surface of the object, which helps to have a deeper understanding of the force state of the object.

[0016] 2. The utility model proposes a new force sensor system with positioning function. The four force sensor mechanisms can work simultaneously and can be checked and compensated with each other. If one sensor fails or has an error, the other sensors can provide redundant information to enhance the stability and reliability of the entire system. Moreover, the four force sensor mechanisms can be flexibly arranged in different positions to adapt to objects of different shapes and sizes. This flexibility makes the system more versatile and can be applied to a variety of scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
