The present invention relates to a transportation device, and more particularly to a transportation device in a clean room.

As Taiwan's liquid crystal panel business has developed considerably, its surrounding industry has been actively developed. As the size of next-generation panels is getting larger, transportation and storage operations in the panel production process will be more dependent on automation facilities. In addition, because they operate in a clean room environment, the demands on the specifications and technical dimensions of these automation facilities are increasing.

Large panels in liquid crystal panel factories are stored in cartridges in warehouses, and transport belts and transfer devices must always be assembled between manufacturing process facilities to automatically transport cartridges. In the prior art, a roller transport belt is generally used as a carrier for a cartridge. However, inaccurate placement of the cartridge during transport or loading and unloading of the cartridge causes the cartridge to be displaced, thus causing direct contact between the roller and the cartridge, resulting in wear and tear of the roller contact surface, thus producing a small amount of particulates. .

Since the machinery in the liquid crystal panel factory is used in a special environment called a clean room, the demand for dust protection measures is also very high. The friction between the rollers and the cartridges creates particulates that affect the cleanliness of the product and the cleanroom, and the wear and tear of rollers must also be updated to increase the number of stops and replacements. . Therefore, there is a need to improve the roller structure in the roller transport apparatus to reduce the production of fine particles and to extend the service life of the roller.

Among them, the roller includes a roller base and a roller supporter, the roller base is connected to one of the side walls, and has a guide inclined surface. The roller supporter protrudes from the roller base and has a rotating shaft inside, and the guide inclined surface is inclined toward the roller supporter. The roller further includes a plurality of guide elements arranged uniformly on the guide inclined surface to guide the article to the roller supporter. Among them, at least one of the plurality of guide elements comes into contact with the object when the transport device transports the object by rotating the roller, specifically, by rotating the rotary shaft in the roller supporter by a predetermined drive source. The guide element may be a bearing.

Another aspect of the invention relates to a roller structure, wherein the roller includes a roller base and a roller supporter, the roller base has a guide inclined surface, the roller supporter protrudes from the roller base and has a rotating shaft inside Wherein the guide inclined surface is inclined toward the roller supporter. The roller further includes a plurality of guide elements arranged uniformly on the guide inclined surface.

The transport apparatus according to the present invention guides an object to be transported to a predetermined position by a bearing which is a guide element. Compared with the prior art, the bearing can guide the position of the object by using a point contact roller method with a relatively low resistivity, which can effectively reduce the friction between the object and the roller, and reduce the production of fine particles. By doing so, it is possible to improve the excellent rate of the product and to extend the service life of the roller.
