Description

Technical Field

[0001] The utility model relates to the field of touch panel testing, in particular to an automatic testing device for the flatness and thickness of a touch panel. Background Art

[0002] The touch panel flatness and thickness automatic testing equipment currently available on the market cannot meet the needs of the touch panel industry's continuous development towards high-end technology, and the market's requirements for touch panel-related product quality are becoming increasingly higher. There are also increasing demands for improving the production and quality of touch panel products both domestically and internationally. However, most touch panel flatness and thickness automatic testing equipment currently available is essentially semi-automated, requiring a large amount of manual labor to complete the testing process. Manual operation is inefficient, and the precise positioning of the touch panel during testing cannot be controlled. Product contamination is difficult to control, resulting in a very high failure rate for touch panel flatness and thickness testing, which cannot meet manufacturers' requirements for high production volume and high quality products.

[0003] Currently, most touch panel flatness and thickness automatic testing equipment has several problems:

[0004] 1. Manual operation cannot automatically complete the flatness and thickness test process. The manual operation method has no guarantee of accuracy, efficiency, and quality, resulting in a decrease in efficiency. In addition, the manual operation process may cause contamination of the test board, reducing the yield rate.

[0005] 2. The equipment has a single function. One device can only complete one process. After completion, the semi-finished product needs to be moved to another place for the next operation, which is very inefficient.

[0006] 3. The completion of flatness and thickness tests is basically judged by the human eye, which has a high failure rate. Unsteady hands during the test will waste time and may also damage the product. Utility Model Content

Press the start button device, and the touch screen product begins to enter the production line.

[0046] When manually placing the touch screen product, after the in-position sensor 806 detects the touch screen product, the stepper motor 3 802 brings the touch screen product to the material stop block 801, and then the X-axis linear module 1 301 in the material picking gantry assembly 300 moves to the top of the material stop block 801;

At this time, the patch nozzle 407 in the QR code attachment assembly 400 picks up the QR code in the QR code docking assembly 700, moves it above the blocking block 608, and then attaches the QR code to the touch screen product.

[0051] Among them, the visual camera 2 404 detects the position of the QR code, the vacuum rotary motor 2 406 compensates for the rotation offset, and the barcode scanner 2 408 scans whether the QR code is valid. If invalid, it is thrown into the invalid code receiving box 407. After the code is applied, the touch screen product follows the assembly line and reaches the blocking block 601, and the product is taken away manually.
