Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of gluing fixtures, in particular to a kind of self-adaptive carbon fiber display screen frame magnet mounting sleeve's gluing fixture. BACKGROUND

[0002] With the further development of current technology and economic situation, the display screen industry has been further developed, and sports events, concerts and even commercial activities in shopping malls have started to use display screens to a greater extent. Like traditional movie industry using old projector for video projection, there are often pictures dark, greatly affected by ambient light, limited clarity and other shortcomings. Using display screen can bring better visual experience to users.

[0003] Traditional display screen uses metal material, and there is no impact when installing at low height, but as the height gradually increases, the metal material display screen frame is particularly heavy, which poses a great safety hazard to the installer. And during outdoor use, the display screen must be exposed to UV light for a long time, and rainwater erosion, which has higher requirements for its oxidation resistance, corrosion resistance and other aspects. Carbon fiber display screen frame is attracting more and more attention from display screen industry practitioners due to its excellent low weight, high specific strength, high specific modulus and corrosion resistance. Although the current carbon fiber material has high cost, longer service life and fewer safety hazards, the display screen manufacturers have started to carbonize the display screen frame of various types of display screens.

[0004] Carbon fiberization is not easy. Carbon fiber products are different from traditional isotropic metal products, and the products are constrained by many conditions during production. If each product of the display screen frame has too much difference, it may affect the customer's use experience during use, which has high requirements for the shape size and flatness of the display screen itself.

[0005] Most carbon fiber display screen frames and display screen lamp bead module boards use magnets and stainless steel parts to attract each other for quick assembly, but the installation and positioning of magnets require precision, which requires a magnet mounting sleeve to control its position.

[0006] Since most of the carbon fiber products need to be made into rough blanks by using the way of mold forming, there is a huge problem of warping and product itself sagging. The rough blank formed by the mold is difficult to show consistency due to the thermal stress caused by the high temperature of forming and the anisotropy of carbon fiber, which makes the flatness of most carbon fiber display frame warping to more than 0.5mm when it is out of the mold, and the special pipe section may even reach more than 1mm. At this time, the frame cannot use the ideal fixed support method to prevent its deformation due to its own weight during the gluing process, and since the warping way of each frame is not uniform, there is a problem that the height of the support point cannot be quantitatively set.

[0007] It is difficult to obtain a high-precision magnet mounting sleeve plane by using the way of integrating the magnet mounting sleeve with the carbon fiber display frame, and since most manufacturers require that the full frame meet the requirements of RoHS 2.0, the magnet mounting sleeve that has been surface treated cannot be processed again. Even if it is processed and then surface treated, there will be a safety hazard that the depth of the magnet sleeve is not the same, and the adsorption capacity of the display screen cannot meet the design requirements, so it is difficult to obtain a high-precision magnet sleeve mounting plane that meets the requirements.
