[0022] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0023] Example 1

[0024] like Figure 1-3 As shown, an auxiliary device for testing the strength of display glass includes a base 2, and a rear side of the base 2 is equipped with... Useful A connecting box 3 is connected to the air source, and a guide head 4 for adjusting the air direction to the base 2 is installed at the front end of the connecting box 3. A wiping roller 5 for wiping the base 2 is provided on the upper side of the base 2. The axis of the wiping roller 5 is set in the left and right direction and abuts against the base 2. Limiting plates 9 are fixedly connected to the left and right sides of the base 2. Limiting grooves 10 are provided on the limiting plates 9. A movable rod 11 is provided on the lower side of the limiting plates 9. An elastic element 8 that provides tension to the wiping roller 5 is connected between the movable rod 11 and the end of the wiping roller 5, so that when the wiping roller 5 is pulled back and forth, the wiping roller 5 automatically presses against the base 2. In use, the device is placed on the glass hardness testing device 1, and then the glass to be tested is placed on the base 2. Before and after the test, the upper surface of the base 2 can be deeply wiped and cleaned by pulling the wiping roller 5. The glass debris generated after the test is cleaned by the guide head 4, providing a clean working surface for the glass to be tested and improving the testing efficiency and accuracy.

[0025] Specifically, the front of the air guide head 4 is equipped with a long strip-shaped air outlet, which can accurately guide the airflow direction and make the airflow evenly cover the glass surface to be tested. The air source can be a fan connected with a hose.

[0026] Specifically, a roller 12 is sleeved on the movable rod 11 and rotatably connected to it via a bearing. Under the tension of the elastic element 8, the roller 12 abuts against the bottom surface of the limiting plate 9, which can effectively reduce energy loss and ensure that the movable rod 11 remains stable during movement, thereby providing a reliable guarantee for the stable operation of the wiping roller 5. Specifically, the elastic element 8 is made of elastic rubber strip.

[0027] Specifically, the base 2 has fixed limit baffles 7 on both sides to prevent the guide plate from moving left and right. The base 2 has a positioning groove 6 for storing the wiping roller 5 at the rear end. The positioning groove 6 is an arc-shaped groove and is located directly below the air guide head 4. The positioning groove 6 has a natural transition. When the wiping roller 5 is stored in the positioning groove 6, it can fit perfectly with the groove. This not only effectively prevents the wiping roller 5 from being damaged by accidental collision when idle, but also avoids the main area affected by the airflow of the air guide head 4, and will not have any negative impact on the airflow distribution of the air guide head 4.

[0028] Specifically, to further save manpower, the left and right sides of the base 2 are equipped with wiping drive components for driving the wiping roller 5 to move back and forth. The wiping drive components include a drive motor, a drive roller 13, a driven roller 14, and a belt 15. The belt 15 is sleeved on the drive roller 13 and the driven roller 14. The belt 15 is connected to the end of the wiping roller 5 through a fixing member 21. The drive motor is connected to the drive roller 13. Specifically, the drive motor is built into the base 2, and a protective cover 20 is provided on the driven roller 14. The drive motor is a servo motor, which can accurately adjust the moving speed of the wiping roller 5 and make the start and stop transitions smooth, avoiding the impact on the wiping roller 5 and the base 2 caused by sudden speed changes. At the same time, the belt 15 is made of rubber composite material, which has good wear resistance, flexibility and smoothness, and can maintain stable transmission performance during long-term operation, providing stable transmission for the wiping roller 5.

[0029] Specifically, the lower front end of the base 2 is provided with a storage groove and a tray 17. The tray 17 is provided with a collection box 16 for collecting waste materials that can be inserted into the storage groove. The collection box 16 has an opening at the top. The front edge of the upper surface of the base 2 is rounded. Under the action of wind and wiping roller 5, the waste materials can fall accurately into the box, preventing the waste materials from scattering into the surrounding environment.

[0030] Specifically, the pallet 17 is provided with a guide groove 18, and the bottom of the collection box 16 is fixedly connected with a guide block 19. 19 years ago The rear sliding connection to the guide groove 18 ensures that the installation and disassembly of the collection box 16 is convenient and reliable, and achieves left and right direction limitation.

[0031] Example 2

[0032] Based on Example 1, a mounting groove is provided on the base 2, and a pressure-resistant plate for supporting the glass to be tested is detachably connected in the mounting groove. The upper end surface of the pressure-resistant plate is flush with the upper end surface of the base 2. The wiping roller 5 abuts against the pressure-resistant plate. The pressure-resistant plate can be made of high-strength, high-hardness alloy material, which can not only withstand greater pressure without deformation, but also has a finely polished surface with high flatness. The design of being flush with the upper end surface of the base 2 ensures that the glass to be tested can be kept in an absolutely horizontal state when placed, avoiding uneven force on the glass during the test due to uneven surface, thereby effectively improving the accuracy of the test results. At the same time, the detachable design of the pressure-resistant plate makes it easy to replace pressure-resistant plates of different specifications or materials according to different test requirements, greatly improving the versatility and flexibility of the device.
