Introduction to the components of the PV Module testing Machine

1, imaging system
The imaging system adopts imported SONY EXview HAD CCD, which has 1.4 million and 6 million users to choose from and supports dual camera mode.

Excellent image quality, SONY EXview HAD CCD, excellent image quality, with semiconductor refrigeration, as low as -20 ° C, eliminating the influence of thermal noise, further improving image quality, integrated design, simple interface, easy to maintain, The CCD camera adopts an integrated design, USB interface power supply and data transmission, and maintenance is simple.

2, motion control unit
The motion control unit is responsible for the flow control of the entire EL fully automatic tester and the manual function commissioning of individual function modules.
The motion control unit collects the state of the sensor to control the workflow of the device, and at the same time, the working state of each unit is known through the sensor. When a working unit fails, the motion control unit can immediately stop the current operation and maintain the state, and through the serial port and The PC interactively sends and receives commands and uploads alarm information.

3, computer control system

(1) Computer configuration professional industrial control computer, good stability, Chinese WindowsXP operating system.

(2) Dedicated defect detection (EL) image acquisition and processing software adopts professional operation interface, simple and clear, Chinese/English operating environment, supports manual marking of defect locations, different defects have different marking symbols, easy to identify, marking results and pictures Save together.

(3) Database management test results, easy to retrieve and find, and interface with the customer database to upload test results.

(4) Provide Ethernet interface, which can interface with the customer production management system, upload test pictures, equipment working status and alarm information.
