Description

1373391 VI. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a maintenance device, and more particularly to a maintenance device suitable for a three-dimensional molding mechanism. [Prior Art] Rapid Prototyping (RP technology) is developed based on the concept of stacking layers of pyramid layers. The main technical feature is the rapid molding, without any tools, molds and In the case of fixtures, the design of any complex shape can be quickly and automatically converted into a 3D solid model, which greatly shortens the development cycle of new products and reduces the cost of research and development. It can ensure the time-to-market of new products and the success of new product development. Rate, which provides a complete and convenient product design communication tool between technicians and technicians: industry decision makers, product users and other non-technical personnel', thus significantly improving the competitiveness of the product market and The ability of enterprises to respond to the market. °° At present, RP technology has developed the H(four)' μ production method that uses the printing technology combined with the precise positioning of the carrier (4). The first layer of the powder is laid on top of the carrier and the high-viscosity glue is printed on part of the powder by spray-printing technology. The mixture liquid is used to make the glue liquid adhere to the powder, and the 3D solid model can be completed by repeating the above process layer stacking. However, the printing equipment used by the conventional RP technology does not seal the 'residual glue will dry 1373391 in the print head or the stored maintenance station', which will result in poor subsequent printing functionality. Can not continue to print high quality 3D products. Although the current RP technology is known as rapid prototyping technology, it does not matter whether the size of the article or the size of the article or how to improve the equipment of the rapid prototyping device. It takes hours or tens of hours to form and is piled up in layers. In the finished product, when the print head itself is blocked, if it is not immediately determined or perceived, it will result in unrecoverable time and material waste. _ In addition, when forming a high-viscosity adhesive liquid, the glue point is sprayed at a speed of up to 8 m/sec. In this ultra-high-speed spray, when the droplet sticks to the powder, the next side is not a droplet. The sticky nano-sized small powder will rebound and fly, and when the powder is fed or picked up, the powder will fly everywhere when the push powder pile is dropped, and the conventional equipment does not have a quantitative powder feeding mechanism. Pushing the excess powder into the recovery cylinder will cause pollution and energy waste when the powder falls. In addition, each time: the powder powder needs to be molded and dried, and it has to wait for several hours to dry after molding, that is, if the forming strength is insufficient or # Inadvertently, it may damage the finished product. Therefore, it is necessary to make the molded product strong enough to be taken out, and the printing positioning accuracy cannot be achieved. Only one-way rapid powdering and printing can be performed, and the total molding time is increased. In addition, when the machine is in standby for a long period of time or the print head is removed, the sheet and the seal in the maintenance station may adhere to the glue and cause hardening. Moreover, the prior art uses a one-way powder application and a one-way nozzle printing device to unidirectionally print its printing die (four) as a precedence to the end point 'final printing from the origin to:: ' The working time is too long and cannot be fully utilized. [S] 4 1373391 Therefore, how to develop a kind of maintenance device that can improve the above-mentioned lack of technology, which is suitable for the three-dimensional (four) structure, is a problem that is currently being solved. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a maintenance device suitable for a three-dimensional molding mechanism, and to solve the problem that the conventional three-dimensional molding mechanism can not seal when the inkjet printing is not performed, and the residual glue will be maintained in the printing head or the storage. The station is dry. • The scraper and seals in the maintenance station will stick to the adhesive and cause hardening. ' ▲ In order to achieve the above objectives, one of the more general implementations of the present invention is to provide a dimensional compliance device, which is suitable for a three-dimensional molding mechanism, which has a printing module with a printing head, and includes: The cover unit comprises a protective cover and at least one sealing member, the at least one sealing portion being placed inside the protective cover, and the printing is covered by the top cover when the printing plate is not in operation a print head of the module; a cover dust-cleaning member for the cover. 〇一Π * Covers the dust protection when it is idle; when it reaches the unit, it includes a rotatable body, a transmission wheel set and at least one to the board, the body is driven by the transmission wheel set E. Linked to the body for cleaning the column I3, 'and the print head, a cleaning dust-proof member covers the dust-proof protection when the scraping unit is idle.
