Abstract
The invention discloses a workpiece length online measuring system and method. The system comprises a controller, a detection device and a feeding device. The detection device comprises a sensor, a material pushing device, a material distributing device and a material discharging device. The method comprises the steps that the feeding device sends workpieces to be detected in the feeding device to the material pushing device through a feeding pipe, the material pushing device pushes the workpieces to be detected to a sensor detection station for detection, the sensor feeds signals obtained through detection back to the controller, and the controller controls the material distributing device to send the detected workpieces to qualified material boxes and unqualified material boxes respectively through the material discharging device according to the feedback signals. The automation degree is high, production cost is lowered, the structure is simple, operation is convenient, the requirement for environment is low, accurate length values of products to be tested can be obtained, errors are reduced, and detection results can be more objective.
Description
Technical field
The invention belongs to the technical field that Workpiece length detects, be specially a kind of Workpiece length on-line measurement system and method.
Background technology
Along with scientific and technological development, the accuracy of detection of product length requires more and more higher, and for high-precision length detection, the general method adopting has two kinds:
The one, adopt high-precision measurer, such as vernier caliper, milscale etc.: but generally can only be used for manual operation, can not programming Control, be also difficult for making automation equipment, in the time of mass detection, be difficult to realize.And for the product to be measured varying in size, may need many cover measurers, flexible not.This detection method not only measuring accuracy is difficult to guarantee, and operation steps is more loaded down with trivial details, and the environmental factor of testing process also affects to a certain extent and detects effect.
The 2nd, adopt camera sampling, the analysis of a high pixel: its detection time is short, and result is more accurate, but this method requires the length of product to be measured less.Generally, in Machine Vision Inspecting System, accuracy of detection is directly proportional to camera resolution, and is inversely proportional to range.Along with the increase of product length to be measured, the pixel value of the camera that sampling needs also increases thereupon, otherwise will reduce accuracy of detection.And the pixel value of camera is not unlimited increase, and the cost of the camera of high pixel is also quite high.
As detecting a 40mm, precision prescribed reaches the length of the product of 0.01mm, need to select the camera that a level (or vertical) resolution is 4000pixel.Even if CCD chip is 1/4 cun, the CCD camera of 4000*1000 (if existence) is also a high input so.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of Workpiece length on-line measurement system and method.
The present invention for achieving the above object, adopts following technical scheme:
Workpiece length on-line measurement system of the present invention, comprise controller, pick-up unit and feed arrangement, wherein pick-up unit comprises sensor, material-pulling device, feeding-distribution device and stripping attachment, in feed arrangement, workpiece to be detected is delivered to material-pulling device by feed pipe, material-pulling device pushes to sensor detection station by workpiece to be detected and detects, the signal feedback that sensor obtains detection is to controller, controller will be delivered to respectively qualified material case and defective body feed tank by stripping attachment through the workpiece detecting according to the signal controlling feeding-distribution device of feedback, controller is controlled respectively feed arrangement, sensor, material-pulling device, the operation of feeding-distribution device and stripping attachment.
Described controller is PLC or MCU.
Described sensor is photoelectric encoder.
The detection method of Workpiece length on-line measurement system is as follows:
Adopt feed arrangement that workpiece to be detected in feed arrangement is delivered to material-pulling device by feed pipe, adopting material-pulling device that workpiece to be detected is pushed to sensor detection station detects, the signal feedback that sensor obtains detection is to controller, and controller will be delivered to respectively qualified material case and defective body feed tank by stripping attachment through the workpiece detecting according to the signal controlling feeding-distribution device of feedback.
Automaticity of the present invention is high, reduced production cost, and the present invention is rational in infrastructure, easy and simple to handle, to environment require lowly, can obtain the length value accurately of product to be measured, reduced error, be that testing result is more objective.
