introduction
To realize length measurement, there are many kinds of principle options, optoelectronics, image methods, etc. By adding sensors to the length measuring instrument, a variety of geometries can be measured. This paper has performed this kind of measuring instrument that can realize multiple functions. Introduction.
1, length measurement speedometer
LED white light speedometer is a non-contact speedometer. Through practical application in various fields, the white light speedometer adopts spatial filtering technology, and LED (Light Emitting Diode) light source and linear array CCD chip realize the linear velocity of space-emitting particles. Measurement. In practical applications, high-brightness LEDs are used to illuminate the surface of the object to be measured. Non-uniform arrangement of particles on the surface of the object to be measured will produce reflected light of different sizes and angles to form luminescent particles. After the luminescent particles pass through the optical lens, It will generate imaging on a dedicated detection device, the linear array CCD, and output a frequency signal proportional to the speed of the luminescent particle at the output of the dedicated signal processing circuit. After this frequency signal is processed and processed, the moving speed of the measured object can be obtained. - The linear velocity, the integration of linear velocity over time is - length.
Can be used to control the flow of cold mill seconds, smoother, elongation control crosscutting, slitting speed length measurement rods, wire and cable length measurements.
2, industrial camera measuring diameter measuring instrument
The industrial camera diameter measuring length measuring instrument adopts industrial camera shooting and image processing technology to realize the detection of the maximum diameter and length value of the two ends of the measured object. The image processing method is to use the camera to obtain a good backlight by applying the backlight to the measured object. The image is processed by software to obtain the required measured value.
In the test, first place the object under test into the inspection position. Fix the middle part of the measured object with a roller or pallet to expose the measurement area so as not to obstruct the view of the industrial camera. The system begins to detect after entering the camera's field of vision. Measurement The original numerical value is fed back to the IPC. The IPC calculates the diameter and length at both ends through software.
3, photoelectric plate length measurement width meter
For the measurement of the length and width of the block plate, photoelectric measurement is used. Measurement instrument The two sets of probes are arranged with a vertical distribution of 90°, one group measures the length of the steel plate, and the other group measures the width.
There is a platform for placing steel plates in the measurement area. There are positioning blocks on the platform. After the steel plate is tightly positioned, the measurement direction and length and width direction of the probe can be ensured. After the system is turned on, it enters the working state. Read the length and width of the plate on the display.
4, Length measuring instrument
The length measuring instrument is composed of two measuring principles. It uses the industrial camera image method to measure the length (two industrial cameras can be used to measure the length of the long length of the board) and uses the photoelectric method to measure the width.
The entire equipment length measuring unit, the width measuring unit and the control cabinet, etc. are as follows: The camera control box (the camera is equipped with an industrial camera and a linear guide slide) 2 sets, 2 linear lasers, 2 width measuring probes, Mounting brackets, control cabinets, industrial computers, monitors and audible and visual alarms.
The distance between the length probe and the width probe can be adjusted separately (without affecting each other), so as to realize the detection of the dimensions of various ultra-wide and long steel plates. The width probe is also equipped with the edge straightness detection function.
Conclusion
The above is the extension function of the length measuring instrument, which can realize measurement of various sizes. Of course, there are also professional length measuring instruments. The function of the product can be added according to the measurement requirements. The length measuring instrument can be used for steel pipes, steel rods, cables, square steel, and steel. Bars, wood and other rolled materials of the length and other tests. And for non-contact measurement, can not detect the rolling material can also achieve high-precision detection.
