CCD visual alignment automatic laminating machine working principle
The working principle of the CCD visual alignment automatic laminating machine is to take pictures of the characteristic positions on the product through a dedicated CCD camera, industrial lens and light source, collect image data through an image processor (PC) for image processing, and perform positioning Calculation is used to determine the actual position of the product, and the actual offset value of the product is calculated by comparing it with the previously set reference position. By controlling the movement of the alignment platform, the product moves to the previously set reference position to achieve rapid, Closed-loop, high-precision alignment.
CCD visual alignment automatic laminating machine main application
The application of CCD visual alignment system is mainly reflected in the application of precise alignment system. Such as COG automatic alignment system, CCD visual alignment thick film screen printing machine, printer binocular vision alignment system, die bonding machine visual alignment control system, target shooting machine control system, matrix distribution LED, fully automatic wire bonding vision system, mahjong identification Machine vision system, barcode recognition machine vision system, surface reading machine vision system, connector flatness inspection system, IC burner automatic positioning system
System structure diagram
The CCD visual alignment automatic laminating machine calculates the offset of the measured object in the XYθ direction by identifying the positioning reference point, and automatically controls the mobile platform to move in the opposite direction by the corresponding amount of movement, correcting the position of the measured object to achieve accurate Automatic positioning.
1. The camera can be placed in any position
The CCD visual alignment system uses an advanced position intelligent detection algorithm (Auto-Calibration). No matter how the camera’s installation direction, orientation, tilt angle, field of view difference, etc. change, the system can automatically detect the camera position through the learning function.
Main performance
2. High-precision positioning. The system core adopts EI edge recognition independently developed by our company, which can achieve fast and high-precision positioning at the sub-pixel level.
The CCD visual alignment automatic laminating machine is divided into two parts: visual automatic alignment and lamination, which can work independently.
Product parameters of various models can be saved at will to facilitate production and use next time.
The alignment is based on the liquid crystal display area and the ink edge of the cover, which solves the problem of lamination accuracy affected by the backlight combination accuracy.
