Problems solved by technology

[0005] In the current technology, although there are many workpiece height detection devices represented by ultrasonic sensors, in the selection of controllers, the design of many controllers fails to fully consider the actual industrial site environment, resulting in unstable operation. This greatly reduces production efficiency

Abstract

The invention discloses a device capable of detecting workpiece height. The device comprises an ultrasonic sensor, a PLC and a touch screen. The ultrasonic sensor is connected with a 24V direct current power source through a red wire, outputs signals through a yellow wire, is connected with an analog input end of the PLC, is grounded through a black wire, and is connected with a common input end of the PLC. The touch screen is in communication with the PLC through a PPI bus. The device capable of detecting the workpiece height is reasonable in design, can be used for detecting the workpiece height in an automated production line, and has the advantages of being high in measurement accuracy, stable and reliable in operation, capable of realizing non-contact workpiece height detection, and quite suitable for being popularized and applied to actual workpiece production lines, and having an intelligent human-computer interaction function.

Description

technical field [0001] The invention relates to a workpiece detection device, in particular to a device capable of detecting the height of a workpiece, belonging to the technical field of workpiece detection. Background technique [0002] The height detection of workpieces in actual industrial sites currently mostly uses electronic scales, linear displacement sensors, etc. The requirements are relatively complex, and it is easy to damage the workpiece. At present, the non-contact detection method represented by ultrasonic sensor has gradually become the dominant position. The core of ultrasonic sensor measurement is ultrasonic distance measurement. [0003] Ultrasonic distance measurement is a non-contact detection method, which is not affected by factors such as illumination, electromagnetic field, and color of the measured object during use. In addition, the information processing is simple, fast, and low in cost. Navigation, liquid level measurement and other aspects h...
