In Tronstol E1, we use CCD 3D flying laser vision(Figure 1) for machine vision. It can ensure that the placement head can collect relevant information of any reel and ensure that the camera has no dead spots when editing and working.

What are the functions of CCD 3D flying laser vision for machine vision:

1. Positioning function: It can automatically locate the position features on the appearance of the inspected product. During the detection process, if these appearance features are inconsistent with the image coordinates provided by the database, it can be judged that the product is a defective or defective product.


2. Measurement function: It can automatically measure the apparent size of the product, and use the CCD camera to shoot the detected product from multiple angles. It can measure the basic values of the product's length, width and height. According to different product measurement requirements, by increasing the number of CCD cameras and adjusting the angle, the measurement accuracy can be improved by 0.001mm, and the size of objects of various shapes can be measured at the same time. The corresponding size obtained through database operation is compared with the inherent data in the database to determine whether the product size is qualified.


3. Recognition function: It can automatically identify the colour, graphics, characters, etc. of the product, and judge whether the characters, colours, and graphics appearing on the detected product are correct through the operation of the database, so as to judge whether the inspected product is qualified.


4. Detection function: It can automatically detect whether there are certain features on the product, and judge the features through database operation. These features of the inspected product have or exceed the original features to determine whether the inspected product is qualified.


Because the CCD 3D flying laser vision is directly embedded in the placement head, the calibration function can be realized between picking up the material and the placement of the material to achieve a true "flying" shooting. In principle, CCD 3D flying laser vision is a cross-section capture technology of side projection, The ultra-high-speed exposure of about 700 frames per second and the optical accuracy of about 0.01mm have inherent advantages for components such as 0201. The laser vision can detect the tip of the nozzle through the linkage control of the nozzle height and realize the unity of the nozzle height. Proofreading can ensure that the uniform height of each nozzle is within 0.1mm. Because the characteristics of the laser principle have strong anti-interference to the colour and reflective characteristics of the nozzle, it has no effect on the whitening and reflection of the nozzle. The performance is particularly prominent in the scenes such as 0201 which are easy to trigger the background interference of the nozzle. Also because the laser vision is embedded in the placement head, the laser vision can detect the suction nozzle when the placement head is idle. When the next work file is loaded, the CCD 3D flying laser vision will perform a round of diameter and concentricity detection of the nozzle tip, which is convenient for users to check whether the nozzle model is correct. In addition, after each material is pasted, the laser will perform a routine inspection on the nozzle tip. It can ensure the components are not brought back. This special function is only available in some high-end placement machines.

Therefore, the CCD 3D flying laser vision enhances the anti-interference of Tronstol E1 scanning, improves the accuracy of placement, especially for 0201, and improves the speed of placement. It is an epoch-making product of the desktop mounter machine, and technological innovation leads the development of the SMT industry.
