Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressure strength detection, in particular to a 3D curved glass cover plate bending strength detection device. BACKGROUND

[0002] The 3D curved glass cover plate is a kind of glass variety, which has the advantages of lightness, thinness, transparency and cleanliness, and is widely used in electronic instruments such as smart phones, smart watches and tablet computers. Because the strength of the 3D curved glass cover plate directly relates to the safety of the electronic instrument, after the 3D curved glass cover plate is completed injection molding, strength detection operation needs to be performed, at which time a strength detection device needs to be used.

[0003] The existing Chinese patent application with the application publication number CN115561088A discloses a glass steel bending strength detection device and method, which comprises a workbench, an installation frame is fixedly arranged on the upper surface of the workbench; a pressing wheel is connected to the installation frame in a lifting manner, which is used to press the glass steel placed on the workbench; a lifting driving part is fixedly installed on the installation frame and connected with the pressing wheel, which is used to drive the pressing wheel to lift; two support combination wheels are arranged in a relative sliding manner, which are used to support the lower surface of the glass steel and drive the glass steel to move; a first sliding driving assembly is used to drive the two support combination wheels to slide relative to each other and adjust the distance between the two support combination wheels; the invention can adjust the movement of the glass steel through the support combination wheels, so that linear detection can be performed and the detection area is wide. The support combination wheels can adjust the distance and promote the movement of the glass steel, which is convenient to adjust and simplifies the structure of the device, reduces the production cost and saves energy.

[0004] However, the strength detection device has the following defects in specific use:

[0005] 1. The existing strength detection device generally adopts a pressing method to detect the strength of the glass (3D curved glass cover plate) when detecting the strength (pressure resistance) of the glass. However, the above structure cannot accurately detect the strength of the glass when detecting the strength of the curved glass because the pressing structure exerts different forces on the curved surface, which may cause detection errors;

[0006] 2. When the existing strength detection device detects the strength (pressure resistance) of the glass (3D curved glass cover plate), the glass being detected is fixed by pressing in order to ensure the stability of the glass detection. However, due to the curved design of the upper and lower sides of the glass, the traditional structure is not firm and stable when supporting and positioning the curved glass cover plate. At the same time, the glass is easily damaged when being supported and positioned by clamping due to the fragile material of the glass, which has low safety. SUMMARY

At this time, the up and down movement of the lower pressing block 706 drives the intermediate pressure detection ball 707 installed at the bottom thereof to move up and down, for detecting the pressure strength at the eccentric position of the curved glass cover plate body 10.

[0091] Therefore, any person skilled in the art should understand that, within the technical scope of the present application, equivalent replacements or changes can be made to the technical solutions and the inventive concept of the present application, and all these should be covered within the protection scope of the present application.
