Description

Rapid prototyping device printing module 【0001】

The present invention relates to a rapid prototyping device, and more particularly to a printing module having two modularized spray rafts which are mutually fitted in opposite directions to a rapid prototyping device disposed on the carrier.

【0002】

Rapid Prototyping (RP technology) is developed based on the concept of constructing pyramid-like layer stacking. The main technical feature is the rapid molding, which can be used without any tools, molds and fixtures. Automatically and quickly convert any complex shape design into a 3D solid model, which greatly shortens the development cycle of new products and reduces R&D costs. It can ensure the time-to-market of new products and the success rate of new product development. Technology provides a more complete and convenient product design communication tool between technicians and non-technical personnel such as technicians and corporate decision makers, product users, etc., thus significantly improving the competitiveness of products in the market and enterprises. Rapid response to the market.

[0003]

At present, RP technology has developed a 3D solid model by using jet printing technology combined with the precise positioning technology of the carrier. The production method is to first lay a layer of powder on top of the carrier and print on part of the powder by using the liquid jet printing technology. The high-viscosity binder allows the binder to adhere to the powder and solidify. The 3D solid model can be completed by repeating the above process layer stacking.

[0004]

Conventionally, the printing module used in the general printing technology is applied to the RP technology. For example, as shown in FIG. 1, the printing module 1 used in the general printing technology is disposed on a host. Body (not shown) for printing. The printing module 1 includes a printing platform 10, a carrier 11 and at least one liquid jet 12, the printing platform 10 includes a frame body 101 and a transmission shaft 102 spanning the frame body 101. On the drive shaft 102, the at least one liquid jet 12 is usually provided with two liquid jets, that is, as shown in FIG. 1, the first liquid jet 121 for accommodating black ink and the color ink is accommodated (for example: a second liquid discharge port 122 of cyan (C), yellow (Y), magenta (M), and the liquid discharge port 12 is correspondingly disposed on the carrier 11, so that the carrier 11 and the spray disposed thereon The liquid helium 12 is movable relative to the drive shaft 102 of the printing platform 10 for X-axis reciprocation.

[0005]

When the printing module 1 performs the printing operation of the RP technology, the printing platform 10 carries the carrier 11 and the liquid jet 12 disposed thereon to perform a reciprocating operation in the Y-axis direction, and then Through the liquid jet 12, the reciprocating action of the X-axis direction of the left and right movements along the transmission shaft 102 can be performed on the bearing base 11, so that the reciprocating operation is performed through the X-axis and the Y-axis direction, and the spray can be performed. The inks of the respective colors contained in the liquid helium 12 are sprayed on the construction material (not shown) laid by the construction carrier (not shown), and the above process is repeated to carry out the layer stacking operation, thereby completing the 3D object. Solid model (not shown).

[0006]

However, in the implementation of the rapid prototyping operation of the 3D object, in addition to accommodating black and color ink, the liquid discharge cartridge 12 needs to additionally accommodate a high-viscosity adhesive to bond the construction material, and then layer The layers are stacked to form a 3D object, so the conventional rapid prototyping device needs to be provided with an additional carrier and a liquid jet for accommodating a high-viscosity adhesive, which results in an increase in the overall volume of the printing module 1. Large, at the same time increase the cost of the carrier and the spray gun.

【0007】

In addition, the position of the ink jet wafer of the conventional liquid jet 12 is the same, so the printing stroke is also fixed to match the length of the nozzle on the ink jet wafer, and the printing speed cannot be accelerated.

[0008]

In view of this, how to develop a printing module capable of improving the rapid prototyping device lacking the aforementioned prior art is an urgent problem to be solved.

【0009】

The main purpose of the present invention is to provide a printing module of a rapid prototyping device, which has two modular liquid jets of the same structure, and each liquid jet has three liquid storage chambers, and two of the liquid storage chambers are used. The inks of different colors are accommodated, and a liquid storage chamber is used for accommodating the adhesive agent, and the printing operation of the rapid prototyping of the 3D object is performed by fitting the opposite sides to the bearing seat.

[0010]

In order to achieve the above object, a broader aspect of the present invention provides a printing module for a rapid prototyping apparatus, comprising: a printing platform having a frame body and a transmission shaft, the transmission shaft spanning on the frame body; The liquid jets are disposed on the transmission shaft; and the two liquid crystal sprays of the same structure are arranged on the bearing seat in opposite directions, wherein each of the liquid jets has a body, and three liquid storage chambers are arranged in the body , respectively, for accommodating different printing liquids, at least two of the same modularized liquid sputum sputum accommodating at least one of the same printing liquid, and the bottom of the sputum sputum is provided with a liquid crystal film The liquid crystal film has a plurality of liquid supply tanks, and each of them is connected with the liquid storage chamber of the body, wherein one of the liquid droplets on the liquid crystal film of the liquid jet is sprayed on the liquid crystal film of the other liquid jet. A plurality of liquid supply tanks are dislocated, and one of the positions of the plurality of liquid supply tanks on the liquid crystal film is cut at the position of the top of the plurality of liquid supply tanks on the other liquid crystal film, thereby prolonging the entire effective printing length.

The heights of the 223y common board flexible circuit boards 222x and 222y are also different on the wall surfaces 221ax and 221ay. Therefore, the electrical contact points 222ax and 222ay on the board are also in a vertical dislocation relationship. In this way, when the liquid jets 22X, 22Y are disposed on the carrier 21, the first latching structure 229ax of the liquid jet cartridge 22X and the second latching structure 229by of the liquid jet cartridge 22Y are respectively coupled to the carrier. The corresponding engaging structures on the 21 are engaged with each other, and are electrically connected to the corresponding connecting portions on the bearing base 21 through the electrical contact points 222ax and 222ay of the liquid discharge port 22X and the liquid discharge port 22Y.

In the case of the ink and the yellow color ink, the transparent adhesive can be doubled in unit time, and the liquid crystals 22X and 22Y of the same structure can be saved by using the two modules of the same structure. It can reduce the printing time.

[0026]

In summary, the rapid prototyping device of the present invention is provided with two liquid crystal sprays of the same structure in the printing module, and is arranged on the bearing seat in opposite directions with each other, and each liquid jet has three a liquid storage chamber, wherein two liquid storage chambers are used for accommodating inks of different colors, and a liquid storage chamber is used for accommodating the adhesive, and is equipped with a liquid crystal film and a flexible circuit board which are extended and have a misaligned length. The common plate structure can achieve the convenience of material management, cost saving, simplified process, and can print twice the length of the same printing stroke, increase the printing amount per unit time, and the like. The arrangement of the first snap-fit structure and the second snap-fit structure, and the relationship of the upper and lower misalignment of the electrical contact points, make it easier to set the spray raft on the carrier to achieve the effect of preventing the stay.
