Description

Technical Field

[0001] The utility model relates to the technical field of display screen glass testing, and more specifically to a display screen glass strength testing device. Background Art

[0002] With the continuous advancement of science and technology and the increasing dependence of consumers on electronic products, the wearable electronic products industry has shown a booming development trend. However, in the competition in this industry, cost control and product quality improvement have become common challenges faced by major companies. In particular, how to ensure the durability of products, especially the anti-drop performance, while pursuing lightweight and portable products has become a research hotspot in the industry. The display screen is the most direct interface for user interaction in wearable electronic products, and its importance is self-evident. The display screen glass is a key component to protect the display module, and its strength directly affects the product's anti-drop ability. Once the display screen glass is damaged in a fall, it will not only affect the user's normal use experience, but may also cause overall safety hazards to the product.

[0003] In the prior art, when performing a drop test on display glass, a common practice is to directly subject the glass to a free fall test. However, this method is difficult to accurately simulate the drop conditions in actual use scenarios, which may result in a large difference between the test results and the performance in actual use. Therefore, we have made improvements on this and proposed a display glass strength test device.

[0004] For example, a Chinese patent (publication number CN207036384U) discloses a drop test device for a glass substrate, and its specification discloses: However, studies have shown that 80% of mobile phones will cause screen damage due to inadvertent drops. Therefore, glass products need to be drop tested before they are used. In the drop test, the glass to be tested is first placed at a preset height from the ground. In order to comprehensively test the drop resistance of the glass, the contact position of the glass to be tested with the ground after it falls to the ground is adjusted at the same time. For example, the entire glass contacts the ground after the glass falls to the ground, the edge of the glass contacts the ground after the glass falls to the ground, or the corner of the glass contacts the ground after the glass falls to the ground. After that, the glass is allowed to fall freely, and finally the damage of the glass to be tested after it falls to the ground is observed. Utility Model Content
