Description

Technical Field

[0001] This invention relates to the field of smart TVs, and in particular to a method and system for tracing TV module light strips by scanning codes. Background Technology

[0002] In the current LCD TV industry, to achieve consistent display effects, in addition to ensuring consistency in the LCD panel itself, the consistency of the backlight LEDs is also crucial. It's generally difficult to achieve uniform color blocks in backlight LEDs; backlight LEDs produced on the same production line typically exhibit a normal distribution of color blocks. If backlight LED manufacturers were required to deliver only products with the same color block, it would result in a large amount of waste, leading to increased raw material costs and resource waste. Therefore, most TV manufacturers accept the use of backlight LEDs with multiple color blocks in the same TV product.

[0003] Therefore, in order to achieve consistency in display effects during the television production process, it is necessary to control the backlight LED color blocks used in each television. Common control measures include:

[0004] 1. Differentiating color blocks by part number will result in an increase in part numbers, making it difficult to distinguish the actual products and easily causing material mixing during the process.

[0005] 2. Differentiating color blocks by order number - the process is difficult to control, and the management pressure of warehousing and production is high. Summary of the Invention

[0006] To address the existing problems, this invention provides a method and system for tracing TV module light strips via QR code scanning, the specific solution of which is as follows:

[0007] A method for tracing the LED strip of a TV module by scanning codes includes the following steps:

[0008] S1, The supplier generates a barcode based on the basic information of the light strip according to certain rules and prints it on the light strip;

[0009] S2, The manufacturer assembles the light strips;

[0010] S3 automatically scans the LED strip using the TV module LED strip scanning and traceability system;

[0011] S4. Perform color block judgment to check if the light strip colors are consistent. If they are consistent, proceed to step S5; otherwise, proceed to step S6.

[0012] S5 uploads the scan result and the result that matches the light color to the system;

[0013] S6, perform manual replacement or repair of the light strip, and then repeat the automatic scanning process of step S3.

[0014] S7. Enter the backlight inspection system to perform backlight inspection. If it fails, query the system when scanning the code. If it is found that the light strip information is not bound and uploaded or the color block is abnormal, return to step S6. If the backlight inspection passes, proceed to step S8.

[0015] S8, module complete.

[0016] Preferably, the basic information mentioned in step S1 includes the part number, color block, and production date.

[0017] Preferably, a system for a TV module light bar scanning and traceability method includes an automatic scanning system, a server system, and a backlight inspection station system;

[0018] The automatic barcode scanning system includes a barcode reader, a main control computer, a data acquisition card, and a photoelectric switch. The barcode reader is fixed at the position of the barcode on the alignment light bar on the production line. The barcode reader is connected to the main control computer via a network cable. The photoelectric switch is fixed on the production line to trigger data acquisition and is connected to the serial port of the main control computer via the data acquisition card. The main control computer starts or stops the automatic barcode scanning system by recognizing the status of the photoelectric switch through the serial port.

[0019] The server system is used to receive the barcode information uploaded by the automatic barcode scanning system, and then determine whether the whole machine barcode corresponds to the actual production order, whether the specifications and quantity of the light bar barcode are correct, search for duplicates between the whole machine barcode and the light bar barcode, and finally send feedback information to the main control computer.

[0020] In the backlight inspection system, at the backlight inspection station, TV modules that pass manual inspection will undergo a barcode scanning process. The operator scans the TV serial number, and after receiving a pass notification from the server system, the operator releases the module. If the server sends an error message, the corresponding repair operation must be performed.

[0022] The present invention also discloses a computer system, including a processor and a storage medium, wherein a computer program is stored on the storage medium, and the processor reads from the storage medium and runs the computer program to execute a TV module light bar scanning and tracing method as described above.
