Description

Technical Field

[0001] The present invention relates to the technical field of pressure intensity detection, and specifically to a bending strength detection device for 3D curved glass covers. Background Art

[0002] 3D curved glass covers are a type of glass with advantages such as being thin, light, transparent, and clean, and are widely used in electronic devices such as smartphones, smartwatches, and tablet computers. Since the strength of 3D curved glass covers is directly related to the safety of the use of electronic devices, after the injection molding process of 3D curved glass covers is completed, strength detection operations are required, and at this time, strength detection devices are needed.

[0003] The existing Chinese patent application with the publication number CN115561088A discloses a glass fiber reinforced plastic bending strength detection device and method, including a workbench, on the upper surface of which an installation frame is fixedly arranged; a lower pressing wheel, which is connected to the installation frame in a liftable manner and is used for pressing the glass fiber reinforced plastic placed on the workbench; a lift driving member, which is fixedly installed on the installation frame and is connected to the lower pressing wheel, and is used for driving the lower pressing wheel to lift; two support combination wheels, which are relatively slidably arranged and are used for supporting the lower surface of the glass fiber reinforced plastic and driving the glass fiber reinforced plastic to move; a first sliding driving assembly, which is used for driving the two support combination wheels to slide relatively and adjusting the distance between the two support combination wheels; in this invention, the movement of the glass fiber reinforced plastic can be adjusted by the support combination wheels, so that linear detection can be carried out, and the detection area is wide. The distance between the support combination wheels can be adjusted and the movement of the glass fiber reinforced plastic can be promoted, the adjustment is convenient, the device structure is simplified, the production cost is reduced, and energy is saved.

[0004] However, the following defects exist when this strength detection device is specifically used: 1. When the existing strength detection device detects the strength (compression resistance ability) of glass (3D curved glass covers), it generally uses a downward pressing method to detect the strength of the glass. However, when detecting the strength of curved glass with the above structure, due to the design of the curved surface structure on the glass surface, the intensity of the force applied by the downward pressing structure on the curved surface is different, and the strength of the glass detected is not accurate enough, and problems such as detection errors are likely to occur; 2. When the existing strength detection device detects the strength (compression resistance ability) of glass (3D curved glass covers), in order to ensure the stability of the glass detection, the glass to be detected is fixed by downward pressing. However, since the upper and lower sides of the glass are set as curved surfaces, the traditional structure is not firm and stable enough when supporting and positioning the curved glass cover. At the same time, due to the relatively fragile material of the glass itself, the glass is likely to be damaged when being supported and positioned by the clamping method, and the safety is relatively low.

[0038] In the 3D curved glass cover plate bending strength detection device of the present invention, when the second drive belt 5031 operates, the intermediate shaft 701 connected by a synchronous wheel key on its inner side will rotate, and the movable disk 702 connected to the side of the intermediate shaft 701 can rotate. When the movable disk 702 rotates, the eccentric rod 703 installed at the eccentric position on its side will drive the lower pressing arm 704 to move up and down, and the lower pressing block 706 rotatably connected to the bottom of the lower pressing arm 704 through the mounting seat 705 can move up and down (on the side of the guiding straight rod 7061). At this time, the up and down movement of the lower pressing block 706 can drive the intermediate pressure detection ball 707 installed at its bottom to move up and down, for detecting the pressure strength at the eccentric position of the curved glass cover plate body 10.

[0039] Limited to this, any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
