New products|CHIOPT introduces a new 360° inspection lens with eight-mirror lens and appearance inspection box
When it comes to simplifying the vision system, peers who know CHIOPT may have a certain understanding of our two products.
360° exterior wall detection lens
When detecting the external defects of some small objects, the traditional scheme is to use multiple sets of lenses and multiple sets of cameras to shoot at different angles. However, this 360° external wall detection lens can use one lens and one camera to shoot from the object, and the information outside the object ring can be formed into a circular coronal image on a picture through the principle of refraction and reflection, simplifying the visual system.
It is suitable for the defect appearance detection of small objects such as bottle caps and screws, because the distortion is large, it is not suitable for dimensional measurement.
360° inner wall detection lens
Correspondingly, there is also a 360° inner wall detection lens for detecting the inner wall information of the object. The left is suitable for the inner wall detection that needs to be reached into the pipeline for shooting, which is the industrial pinhole lens, which can clearly detect the hidden internal features and defects. The right lens is shot above the object, and the special optical structure enables it to have a large Angle of view and a large depth of field, which can expand the inner wall information. Inner wall shooting is suitable for detecting objects such as cylinders, holes, bottles and threads.
The above external wall lens also has limitations, and is only suitable for detecting small objects with an outer diameter of 30mm or less.
Therefore, the CHIOPT launched an eight-mirror lens to shoot the object through eight angles, and the detection range is 5mm to 70mm. The front end is a large field of view telecentric lens, through a special refraction light path, can detect the outer wall and the inner wall of the object respectively, when the size and height are appropriate, can detect the inner and outer walls of the object at the same time, to a greater extent to simplify the system and save costs.
For a bottle cap as tall as the one below, a regular 360-degree outer wall lens needs to be shot at least twice apart - once above and once below. The eight-mirror lens can be shot completely at a time, and the inner wall information like these fasteners can also be shot under the right circumstances, which is the advantage of the eight-mirror lens, but because it is divided into eight faces, it can not do the picture stretching synthesis of the traditional 360° lens.
360° appearance test box
The above product test objects are short length cylinders, and when encountering long length test objects, it is usually necessary to divide into 2-3 times to take pictures, or use four cameras to shoot a product.
So the long trail launched appearance detection box! Through a detection box + a lens + a camera can shoot the outside of the ring of a product, reducing the purchase cost of the lens and camera. The top of the product is equipped with a ring light source to fill the light, which can shoot objects of various shapes and sizes. This product is not only limited to shooting cylinders, and the shape size of the item can be detected within φ75mm x 175mm. Mainly used in cylindrical battery shell, beverage bottles, medicine bottles detection.
