Nowadays, the application of automation and labor saving in the printing industry is becoming more and more common, and the CCD visual alignment screen printing machine in the precision printing manufacturing industry with strict printing requirements is becoming more and more popular. The screen printer with ccd visual alignment has fast alignment speed and high alignment accuracy, which is more suitable for LED ceramic substrates, LTCC, MLCC, filters, ceramic capacitors, resistors, thick film circuits, ceramic circuits, filters, sensors , Ceramic thick film circuits, biological circuits, solar silicon wafers, liquid crystal displays (LCD), signal displays (LED), electroluminescent sheets (EL), and various chip components and electronic components and film coating printing Process manufacturing.

　　The working principle of the vision system of the CCD alignment thick film screen printing machine is to obtain high-definition images of the learning workpiece through two alignment cameras. By searching for the target, first obtain the alignment reference point for learning. The follow-up workpiece is notified by the high-speed vision algorithm to move the three-axis motion platform, so that the position of the alignment reference point coincides with the position of the alignment reference point to complete the intelligent, fast and precise alignment work, and the total after calibration is screen printed.

　　CCD alignment thick film screen printing machine application fields:

　　1. In the circuit board industry, ring-shaped LED lights are generally used, and the target provided by the customer is very clear and the brightness is large; the colors are generally white and red.

　　2. In the optoelectronic industry, generally coaxial light sources, strip lights, and various types of light are used, such as blue light, white light, UV light, etc. The surrounding environment of the general target is more complicated and difficult to distinguish by the naked eye
