Abstract
The invention discloses a kind of machine vision device of double-face imaging, comprise camera, mirror, wedge, mounting groove and trip bolt; Described mounting groove is rectangular build, its centre, bottom has the through hole of strip along its length, in mounting groove, be provided with wedge, the bottom of wedge is provided with trip bolt, trip bolt is through through hole, fix by clamp nut, be provided with mirror on wedge, a side and the mounting groove of mirror are hinged; Described camera be arranged on mounting groove directly over. The present invention has realized a camera and has gathered simultaneously the positive and negative both sides image of a workpiece, has realized the high flexibility of adjusting imaging effect, can adjust according to concrete workpiece feature at any time; Total does not produce larger variation because of extraneous variation of ambient temperature, ensures good environmental suitability; Simple in structure, convenient disassembly, can take off at any time device and clear up maintenance.
Description
Technical field
The invention belongs to equipment installing area, especially field of machine vision, is specifically related to a kind of machine vision device of double-face imaging.
Background technology
The application of machine vision technique in the detection of industrial products is more and more extensive, for the characteristic information of complete detection product, often can new requirement be proposed the ancillary equipment except camera to vision system, in real world applications, there is problem: (1) camera can only gather the image of a face of workpiece, gathering positive and negative two surface informations of workpiece at least needs two cameras, and this certainly will will increase the cost of vision system; (2) the vision detection system great majority in commercial Application are all arranged on streamline, and positive and negative is installed by camera and conveyer motion produces conflict; (3) positive and negative installation camera will cause light source there is no local installation, and the system of back side polishing directly cannot be applied; (4) even feasible, how a pair of light source and camera will increase the cost of system. In addition, in complicated industrial occasions application, also require installation frame will have regulating power flexibly at vision system, also do not have at present a covering device can offer NI Vision Builder for Automated Inspection, can gather the positive and negative information of workpiece. The information that only detects a face of workpiece will directly cause substandard product to flow to next process or enter consumption market, shock resistance missionary society makes the image information of vision system collection have fuzzy shape shade, the limited flexibility that makes vision system of regulating power reduces greatly, these all make traditional vision system can not reach desirable testing requirement, have also restricted the application of machine vision simultaneously. The features such as based on the online test method of machine vision technique, fast with its detection speed, precision is high, and measure the item is many have wide application in industry manufacture.
Summary of the invention
The present invention is directed to prior art deficiency, a kind of machine vision device of double-face imaging is provided.
The machine vision device of a kind of double-face imaging of the present invention, comprises camera, mirror, wedge, mounting groove and trip bolt;
Described mounting groove is rectangular build, its centre, bottom has the through hole of strip along its length, in mounting groove, be provided with wedge, the bottom of wedge is provided with trip bolt, trip bolt is through through hole, fix by clamp nut, be provided with mirror on wedge, a side and the mounting groove of mirror are hinged; Described camera be arranged on mounting groove directly over.
In order to guarantee areas imaging in field depth, mobile wedge suitably regulates minute surface inclination angle, and adjustable range is 8～30 °, calculates, wherein while specifically use at the scene according to following depth of field formulaFor lens focus,For lens shooting f-number,For focusing from,For allowing disperse diameter of a circle;
。
The beneficial effect that the present invention has:
1. realized the positive and negative both sides image that a camera gathers a workpiece simultaneously.
2. realized the high flexibility of adjusting imaging effect, can adjust according to concrete workpiece feature at any time;
3. total does not produce larger variation because of extraneous variation of ambient temperature, ensures good environmental suitability;
4. simple in structure, convenient disassembly, can take off at any time device and clear up maintenance.
Brief description of the drawings
Fig. 1 is structural front view of the present invention;
Fig. 2 is the top view of double-face imaging device of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further explained.
As shown in Figure 1 and Figure 2, the machine vision device of a kind of double-face imaging of the present invention comprises camera 1, mirror 3, wedge 4, mounting groove 5 and trip bolt 6;
Described mounting groove is rectangular build, its centre, bottom has the through hole 7 of strip along its length, in mounting groove, be provided with wedge 4, the bottom of wedge 4 is provided with trip bolt 6, trip bolt is through through hole 7, fix by clamp nut, be provided with mirror 3 on wedge 4, a side and the mounting groove of mirror are hinged; Described camera 1 be arranged on mounting groove 5 directly over;
When work, by workpiece 2 be arranged on camera 1 under, move and can make wedge 3 promote the rotation of mirror 1 by trip bolt 2, thereby cause the Angulation changes of minute surface and workpiece.
