Description

Technical Field

[0001] The utility model relates to the technical field of target material processing, in particular to a molybdenum wide target surface processing device. Background Art

[0002] With the development of science and technology, molybdenum has begun to emerge in many emerging fields, changing human life in all aspects. The most relevant to people's lives is its application in the manufacture of flat-panel displays. Large-size high-purity molybdenum sputtering targets are the key core raw materials in the manufacture of liquid crystal flat-panel displays, and molybdenum is one of the preferred materials for sputtering targets for flat-panel displays. Such targets are needed for the screens of electronic products such as color TVs, smart phones, tablet computers, and some large household appliances used in daily life, as well as the control display screens of some military communication equipment.

[0003] As a new type of component for LCD flat panel devices, molybdenum can greatly improve the performance of LCD screens in terms of brightness, contrast, color and lifespan. Displays using molybdenum have unique advantages in environmental protection, compact size and energy saving. Currently, in the production of LCD displays in developed countries abroad, the use of traditional materials such as nickel and chromium is decreasing and gradually being replaced by molybdenum. Although the amount of molybdenum used is small, it plays an important role in the development of large-screen, high-definition televisions.

[0004] At present, large-size high-purity molybdenum sputtering targets are made by powder metallurgy, mainly through cold isostatic pressing, high-temperature sintering, rolling, machining and other processes. The maximum size is 1800x2300mm, and the machining surface roughness requirement is Ra≤0.8μm. Manual surface grinding is labor-intensive, inefficient and uneven in grinding effect, and requires the use of automated equipment such as sanding machines. Before grinding, the molybdenum wide target slab is placed on one side of the conveyor roller, and the equipment is started. The molybdenum wide target slab is conveyed by the roller into the grinding dark box. There are 3 sets of annular sandpapers in the dark box that can rotate clockwise by tension. The upper surface of the molybdenum wide target slab is ground by sandpaper. When the molybdenum wide target slab comes out of the dark box and reaches the other side of the roller, the direction of rotation of the roller is reversed, and the slab re-enters the dark box for grinding, and the cycle is repeated until the surface roughness meets the requirements. However, the characteristics of the equipment itself lead to the fact that the heads of the two ends of the molybdenum wide target slab first enter the contact grinding sandpaper each time grinding, resulting in arc collapse on both sides of the head of the molybdenum wide target slab. Utility Model Content

[0005] The utility model aims to provide a molybdenum wide target surface processing device, which can ensure that the surface of the molybdenum wide target is evenly stressed during surface grinding of the molybdenum wide target, improve the integrity of the molybdenum wide target, and avoid the occurrence of arc edge collapse of the molybdenum wide target due to relatively greater stress on both sides of the head of the molybdenum wide target slab.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a molybdenum wide target surface processing device, comprising a horizontally arranged frame, a conveying roller is horizontally arranged on the frame, and a grinding assembly is also arranged on the frame, the conveying roller is used to horizontally convey the molybdenum wide target slab, the grinding assembly is used to grind the molybdenum wide target slab, the outer cover of the molybdenum wide target slab is provided with an anti-collapse tooling, the anti-collapse tooling comprises two relatively arranged protective frames, the two ends of the protective frame are respectively detachably fixedly connected to the two ends of the other protective frame by screws, the inner diameter of the protective frame matches the width of the molybdenum wide target slab, and the length of the screw matches the length of the molybdenum wide target slab.

[0007] Preferably, the two ends of the protective frame are arc-shaped corners that match the four corners of the molybdenum wide target slab.

[0008] Preferably, both ends of the screw rod are provided with threaded parts, and both ends of the protective frame are respectively provided with screw holes matching with the threaded parts, and also include nuts for fixing the threaded parts after passing through the screw holes.

[0009] Preferably, the screw is made of stainless steel.

[0010] Preferably, the grinding assembly comprises a grinding dark box, and a plurality of groups of grinding sandpaper are arranged in the grinding dark box.

[0011] Preferably, the material of the protective frame is steel plate.

[0012] The beneficial effects of the utility model are:

[0013] This solution provides an anti-collapse tooling on the outer jacket of the molybdenum wide target slab, which can ensure that the surface of the molybdenum wide target is evenly stressed during the surface grinding process, improve the integrity of the molybdenum wide target, and avoid the relatively greater stress on both sides of the head of the molybdenum wide target slab, which leads to the occurrence of arc edge collapse of the molybdenum wide target. The grinding assembly includes a grinding dark box, and a plurality of groups of grinding sandpaper are arranged in the grinding dark box. The equipment can replace manual grinding to improve production efficiency. Both ends of the screw are provided with threaded threads, and the two ends of the protective frame are respectively provided with screw holes matching the threaded threads, and also include nuts for fixing the threaded threads after passing through the screw holes. The anti-collapse tooling can be disassembled and removed when not in use. The equipment is simple as a whole, low in cost, quick and convenient to operate, and highly practical.
