AI Technical Summary
Hollow core motors cannot be fitted with traditional contact pressure sensors, making it impossible to monitor the pressure exerted on the product surface when adsorbing products, and thus impossible to accurately control the working height.
A pressure testing device was designed, comprising a hollow motor, a suction nozzle, an air inlet, a test platform, and strain gauges. The device monitors the deformation of the test platform using strain gauges to detect the pressure changes of the hollow motor on the product surface in real time, and uses photoelectric switches and amplifiers to feed back signals to the terminal to adjust the working height.
It enables pressure monitoring during product adsorption by hollow motors, ensuring precise adjustment of the working height, preventing overpressure, and protecting the product.
