Description

Full-automatic cylindrical glass stick visual detection equipment

Technical field

The utility model relates to cylindrical component testing equipment fields, and in particular to full-automatic cylindrical glass stick vision-based detection Equipment.

Background technique

Many kinds of, the small glass bar to stirring of daily middle cylindrical component, arrives automobile shafts etc. greatly, is all in cylinder Shape.Camshaft, crankshaft especially in automobile etc., are all particularly important components, and geometric tolerance and overall size are shadows The principal element of automotive performance is rung, therefore is typically necessary after manufacture and the cylindricity of cylindrical component is detected.

Cylindricity measurement is the measurement in length metering technology to cylindricity error.When measurement, the gauge head of linear transducer Several cross sections that tested cylindrical body is measured along precise linear guide, can also be along measured cylinder surface sampling for the helical movement.In recent years Come, cylindricity can also be detected by several industrial cameras.

With the rapid development of machine vision imaging sensor, industrial camera is divided into line-scan digital camera substantially from scanning theory And area array cameras, and scanning speed is higher and higher, and line-scan digital camera is up to 120Kline/s, and area array cameras acquisition speed also reaches 500FPS (refresh rate).In current detection application, line-scan digital camera is mainly used for printing checking, planar disfigurement detection；Face battle array Camera is detected for overall size, and image procossing compares, the demands such as positioning.

In recent years, cmos image sensor technology developed rapidly, and had the area array sensor time for exposure of global exposure can In about 10us or so, output control function is powerful for control, and 1line output can be realized by AOI (automatic optics inspection) function, Output frame rate can also realize face battle array 1280*1024 output also up to 30kline/s, this is just in some industry spot applications The advantages of occasion is in combination with line-scan digital camera and area array cameras, improves efficiency, and saves cost.

The periphery Image Acquisition of cylindrical body is generally scanned by the way of object rotation with line-scan digital camera at present, then Software expands into flat image processing；

Diameter and height for cylinder then add back light to acquire image by area array cameras, demarcate a pixel first Corresponding size can then calculate diameter and height according to the diameter number of pixels of workpiece and height number of pixels.Usual situation Lower requirement detects two aspect contents, then mature solution is exactly the diameter and length with table top array camera measurement cylinder Degree is unfolded cylindrical side with a line-scan digital camera, detects side face defects.

Currently, the Chinese patent of Publication No. CN204535628U discloses a kind of cylindrical workpiece cylindricity detection device, It includes pedestal, it is characterised in that the datum level of setting two at an angle on the pedestal, opposite with datum level one Limiting device is arranged in side, and workpiece for measurement is clamped between the limiting device and datum level, also sets up and is used on the pedestal Detect the gauge head of workpiece.Cylindrical workpiece is tightly attached to datum level with special detection device by the utility model, and by dial gauge and bottom Seat is fixed, while gauge head is surveyed on cylindrical workpiece periphery.Cooperation moving in rotation cylindrical workpiece passes in and out gauge head, reads dial gauge Upper indicating range (very poor=maximum value-minimum value), it is its cylindricity that this is very poor.

Although this cylindrical workpiece cylindricity detection device can fix workpiece more conveniently, examined relative to laser The detection with industrial camera is surveyed, this device low precision, detection speed are slow, are unfavorable for the realization of industrial automation.

And the Chinese patent of Publication No. CN207439363U discloses a kind of piston face cylindricity detection device, including Workbench equipped with hollowed out area and motor mounting rack, the laser detector to detect outer surface of piston cylindricity, to adjust The work that the detector of whole laser detector position adjusts component, balances on the motor shaft of rotating electric machine and to adjust piston Plug adjustment component.
