Description
Technical field
The present invention relates to thin-wall pipes laser micro-machining technology, particularly relate to the detecting device of Medical rack.
Background technology
Medical rack implantable intravascular can play the effect of bracing frame, thus keeping opening of blood vessel.Medical rack must is fulfilled for strict job requirement, if support comprises any coarse or sharp-pointed limit, it will damage the hemocyte or blood vessel wall of implanting support place, and this will cause further angiopathy, so that having potential life danger.General, the minor variations of parameter in process for making, defect all can be caused such as laser power, pipe diameter size or machinery vibration.Because the inefficacy that support is functionally would potentially result in life danger, therefore support machine after detection be even more important.
Existing detection means has manual detection and visual system automatically to detect.Manual detection is support product to be detected in turn by microscope by people.But, there is bigger error in manual detection.It addition, manual detection is relatively slow and the relative cost of manufacturing process can be made to promote.And existing vision automatic checkout equipment is extremely complex, and complete equipment is expensive.
It is thus desirable to a kind of simple, low cost and efficient support detecting device.
Summary of the invention
It is desirable to provide a kind of simple, low cost and be effectively used for the device of detection support product.
For solving above-mentioned technical problem, the invention discloses a kind of medical support detection device.This detecting device includes: roller assembly, for driving support rotary sample to detect the regional of support sample；Transverse illumination light source, for illuminating the exterior surface area of support sample；Longitudinal illumination light source, for illuminating the inner surface area of support sample；It is arranged on the electronics line array CCD above support sample, for support sample being scanned with by-line scan mode, to obtain the general image of support sample；The image processing apparatus coupled with electronics line array CCD, for processing the data of electronics line array CCD collection；And the display device coupled with image processing apparatus, for showing the result of image processing apparatus.
This structure of the detecting device provided by the present invention is simple, with low cost, and can quickly qualified and underproof support product be distinguished.

Detailed description of the invention
Each preferred embodiment of the present invention described below.It is to be understood by those skilled in the art that detailed description herein is not intended as limiting the scope of the invention, the present invention is achieved also by modification or other equivalent way of following embodiment.
Generally there will be the defects such as pollution, otch inefficacy, contact point, island shape defect, damage, pitting, deformation after support processing.Generally, as it is shown in figure 1, common defect is just like the shape defect shown in a, the geometric error shown in b and the boundary defect shown in c.
Fig. 3 illustrates detecting device according to an embodiment of the invention.As it can be seen, this detecting device specifically includes that the image processing apparatus of roller assembly, transverse illumination light source, longitudinal illumination light source, electronics line array CCD, display device, Based PC.
Roller assembly is used for driving support rotary sample, in order to the regional of detection support sample.Exemplarily, roller assembly can include with lower component: installs side plate, driven roller bearing, cutting ferrule, actively roller bearing, shaft coupling, motor, as shown in Figure 2.The output shaft of servomotor is connected by shaft coupling with actively roller bearing, and the actively roller bearing that rotarily drives of motor rotates.Actively roller bearing and driven roller bearing are connected by cutting ferrule, therefore when active roller bearing rotates, driven roller bearing can be driven servo-actuated.When detecting, can being placed on by support sample on two feeding roller bearings, the support that rotarily drives of the two feeding roller bearing rotates, for instance support can be driven to carry out 360 degree of rotations.Operator need only to put and take off support product.
Electronic array CCD is used for detecting sample, and it is arranged on the top of support product, gathers the view data of linear array in the precision sweep mode of one line of a line.After a complete scanning process, so that it may obtain the general image of support.
The detecting device of the present invention is introduced from outside into transverse illumination light source and longitudinal illumination light source, and wherein transverse illumination light source illuminates the outer surface of detected support product, and longitudinal illumination light source illuminates the inner surface of detected support.Two kinds of light sources adopt the illumination of different colours and material, and the concordance illumination without high light improves picture quality.
Detecting device also includes image processing apparatus and user's display interface of Based PC.Image processing apparatus utilizes image processing algorithm that the CCD view data gathered is processed, and to observe structure or the surface defect of number of different types, and these defects is compared with original adopted theory or design basis, to be shown on computer interface.Specifically, the support geometric feature sizes that image processing apparatus passes through to record in detection process is compared with the theoretical principle data of support, it is determined that the variable quantity between support measurement data and theoretical principle data.After error is observed, system will visualize these errors of display on the computer screen, thus drawing judged result.
