New description: [New technical field] This creation is about a roller structure, especially for a flat roller display (FPD, Flat PANEL Display) glass substrate carrying device. [Prior Art] In order to meet the increasing demand for the glass substrate size of flat panel displays, since the third generation of products in 1994, glass substrates have been reported to be difficult to handle by hand, and the carrier equipment of glass substrates has become the production of flat panel displays. One of the most important devices. At present, although the air-floating platform has become the new research and development focus of the substrate carrying equipment, its technology is not yet mature, and the cost is still quite high, so it cannot be actually used on the production line. Nowadays, the substrate carrying equipment transported by the rollers is still the mainstream used in the production line--the roller is the important component of the substrate carrying equipment for the roller transport, and the number of uses is large, and it belongs to the components that can be worn, so if the roller can be reduced The frequency of replacement can relatively reduce the process cost of the entire flat panel display. The roller (1) which is generally used for such a device is as shown in the first figure, and the conventional roller (1) is a wheel-shaped structure of a single member. The materials used to make such rollers are mostly based on engineering plastics, because the mechanical properties of such materials are close to metal materials, such as strength, hardness, and light weight, heat insulation, insulation, and forming. Easy advantage. Materials commonly used in wave wheel manufacturing, such as ultra high polymer poly (Mr. Ultra 5 M296236)

In addition, the rollers made of pEEK have higher hardness and better wear resistance, but the price is also higher. Therefore, it would be helpful to develop a roller structure that is both wear resistant and low cost. [New Content] The purpose of this creation is to provide a carrier device that can be both a pure-resistance and a low-cost roller structure, and which can be used as a flat display substrate. In order to achieve the above object, the roller structure proposed by the present invention is a roller member having a pulley member having an outer ring surface having the first; the fish being an annular structure, and the second roller member -in: corresponding to the first inlaid pattern and closely attached - second inlay::, in the middle structure: ring = set in the first - roller member table: -: the brother of a roller member and the second roll {The surface, which is in close contact with the second shape, is the roller structure, and the engineering plastic (4) = the wheel member and the first member which are worn by the first-fake two roller members are higher in hardness than the first roller member. And the embossing of the first and second inlaid patterns of the second roller ensures that the first roller member μ_heat is particularly limited, and is not separated from each other. As a specific embodiment of the present invention, the material of the first roller member can be UPE 'and the younger> a roller member can be made of PEEK ^ as another kind of the creation. In one embodiment, at least one groove may be disposed on the first roller member on two sides perpendicular to the axial direction of the shaft hole of the first roller member to further save the use of the first roller member. Material, but the arrangement of the groove is based on the mechanical support strength of the roller structure and the balance during rotation. As another specific embodiment of the present invention, the roller structure of the present invention is that the first roller member is manufactured by injection molding, and the material for manufacturing the second roller member is coated on the first roller member by another injection molding process. The outer roller is molded so that the first roller member can be brought into close contact with the second roller member to form the roller structure of the present invention. With the roller construction described above, the present invention provides a roller having a high hardness and good wear resistance, but at a low cost. The construction of the roller of the present invention will be further described below by way of specific embodiments and drawings. The following examples and illustrations are intended to be illustrative and illustrative only and not to limit the scope of the claims of the present invention, and those of ordinary skill in the related art, without departing from the spirit and scope of the present invention, Some changes or improvements have been made to these embodiments and drawings. [Embodiment] The roller structure (2) provided by the present invention is as shown in the second figure, which is composed of a first roller member (21) located inside the roller structure (2) and a second portion located outside the roller structure (2). The roller member (22) is composed of. As shown in the third figure, the seventh M296236 - roller member (8) is an annular structure having a shaft hole, and the outer ring surface (2) has the first technique (2 (2). The second roller member (10) is also an annular structure" The ring surface (211) is disposed around the outer portion of the first tear wheel member (2), and has a second inlaid pattern (222) and a first inlay on the inner ring surface (22). ) Corresponding and close. The first roller, the member (21) and the second roller member (22) form a roller structure (2) of the present invention by the close contact of the first inlaid pattern (212) and the first inlaid pattern (222). In order to further reduce the material, the first roller member may be another state (2Γ) as shown in the fourth and fifth figures, which is attached to the two sides (213) perpendicular to the axial direction of the shaft hole of the member. , with at least one (214). The arrangement pattern of the groove (214) is not particularly limited as long as the material can be reduced, and the mechanical strength of the roller structure and the balance during rotation can be prevented. In the case of the roller structure of the present invention, the first roller member may be first manufactured by the injection molding, and the material of the roller member may be coated on the outside of the first roller member by another injection molding process. The first roller member can be brought into close contact with the second roller member, and the material of the second roller member can use UPEK, and the material of the second roller member can use PEEK. The roller structure (2) of the present invention can be mounted on the substrate carrying device (3) as shown in the sixth figure. ^ [Simple description of the diagram] The first figure shows the structure; M296236 • The second diagram shows the structure of the roller.
