Online detection system for the appearance of large-screen module – product brief
After the assembly of the power supply, network, image display and other functional modules of the whole TV set, the information collection, filing, sealing, aging, final testing and packaging will be carried out before leaving the factory. The inspection station of assembling appearance is located before the sealing station. The bar code of each module is collected by the manual handheld bar code scanning gun and the whole machine bar code is pasted at the end to form a whole data and information combination, which is submitted to the management system.
At the same time, by manually identifying and judging the insertion state of the connector of each module, the operator’s actions are repeated and easy to fatigue, and the terminal leakage is easy to occur. In addition, due to the inconsistent orientation of the various modules, the operator is required to adjust the scanning gun according to the direction of the bar code.
Online detection system for the appearance of large-screen module – technical scheme
- Adopt the gantry frame structure to span on the existing production line body;
- Use global positioning camera to measure the position and posture of the workpiece, and guide the movement mechanism to the modified scan point for operation;
- The moving mechanism uses a three-axis vertical coordinate manipulator to drive the scanning camera to each scanning point to identify the bar code and the detection terminal. The number of the target collection points is set according to the actual product requirements;

Identifying barcode types include: EAN-8, EAN-13, Code128, Code39, Code93, Code25, ITF25, Matrix25, UPC-A, UPC-E, QR, PDF417, etc.
Online detection system for the appearance of large-screen module – detection terminal
For different sizes and types of terminals, it is realized that the plug of the measuring terminal is not fully inserted into the socket, and the plug is inclined. The unified algorithm makes the measurement error less than 0.5 mm, including but not limited to the following terminals. It can be customized according to actual project requirements;
Online detection system for the appearance of large-screen module – technical feature
- The global positioning camera can actively determine the position and direction of the TV set on the assembly line, without the need for mechanical positioning correction, thus avoiding the incidental loss and increasing the detection beat;
- Guide the robot arm to drive the local detection camera to realize the accurate measurement of the original detail, and maximally support the identification of the bar code and the component detection in the full range of the 75″ TV set;
- With customizable scanning points, the system can adapt to optimal detection path;
- The bar code recognition accuracy is higher than the industry level and supports one-dimensional and two-dimensional bar code commonly used in industrial and logistic applications;
- Customizable measuring scheme of plug-in terminal type can meet the needs of various products;
- With flexible installation scheme, it can be quickly installed in any location of the production line, and can be used by teaching;
- Customizable communication protocol can facilitate quick docking of host computer (such as MES);
