Description

Automated 3D forming operating system

This case relates to an operating system, especially an automated 3D forming operating system.

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 inkjet printing technology. The high-viscosity adhesive allows the glue to adhere to the powder and solidify. The 3D solid model can be completed by repeating the above process layer stacking.

Conventionally, the printing module 1 used in the general scanning reciprocating printing technique is applied to the RP technology. For example, as shown in FIG. 1, the printing module 1 used in the general scanning reciprocating printing technology is disposed on a main body (not shown) for performing a printing operation. The printing module 1 includes a printing platform 10, a carrier 12 and at least one inkjet head structure 11. The printing platform 10 includes a frame body 101 and a transmission shaft 102 spanning the frame body 101. The at least one inkjet head structure 11 is disposed on the carrier 12, so that the carrier 12 and the at least one inkjet head structure 11 disposed thereon are opposite to the sprayer The drive shaft 102 of the printing platform 10 is reciprocating in the X-axis direction.

When the printing module 1 performs the printing operation of the RP technology, the X-axis direction reciprocating is performed through the printing platform 10 with the carrier 12 and the at least one inkjet head structure 11 disposed thereon. Actuating and reciprocating through the inkjet head structure 11 on the carrier 12 along the drive shaft 102 for moving left and right in the Y-axis direction, thus interacting through the X-axis and the Y-axis direction In the reciprocating operation, the high-viscosity adhesive contained in the ink jet head structure 11 can be sprayed on a construction material (not shown) on which a construction vehicle (not shown) is laid, and the above process is repeated. The layering work is carried out to complete the solid model of the 3D object (not shown).

The above-mentioned conventional scanning reciprocating printing technology uses the printing technology of the printing module 1 to apply to the RP technology to produce a 3D solid model, but it can be known from the foregoing description that this method still needs more in the molding speed. The shafts (ie, the X-axis and the Y-axis) are mutually displaced to the construction material laid on the construction vehicle to perform the printing operation. Even if 2 to 4 layers can be printed per minute, when forming a larger-sized object, the non-stop The interleaving displacement time takes several hours or even longer to form.

In addition, the above-mentioned conventional scanning reciprocating printing technology uses the printing technology of the printing module 1 to apply to the RP technology to produce a 3D solid model. On the RP technology implementing device, the volume size of the construction chamber is often considered. The ink jet head structure 11 of the printing module 1 can scan the reciprocating optimum precision stroke, and thus the size of the construction chamber of the solid model to be molded into 3D is also limited.

Therefore, as far as the rapid prototyping equipment industry is concerned, the technical bottleneck faced by it is the molding speed problem. How to improve these problems is a major problem that the industry needs to solve urgently.

Therefore, in this industry, RP technology has developed a rapid prototyping device for page width printing, which solves the problem that the conventional scanning reciprocating printing technology is used for rapid prototyping, which results in slow molding speed and 3D solid model volume. The problem of limitations, as well as the use of a wide-format printing module of appropriate size requirements to configure a large-sized construction chamber design to complete the formation of larger-sized 3D solid models.

However, at present, the rapid prototyping device is configured with a large-sized construction chamber to complete the formation of a larger-sized 3D solid model, but how the formed 3D solid model is in a large volume. The removal of the size of the construction chamber is another major issue that is urgently needed in the industry.

In view of this, how to develop a molding device with a high molding speed and a simple operation is an urgent problem to be solved.

The main purpose of this case is to provide an automated 3D forming operation system, which solves the problem that the 3D solid model is removed from the construction of a large-sized construction chamber, and the automatic operation system for automatically constructing the chamber is used. A rapid prototyping device that achieves a fast forming speed and automatically and quickly takes a molding cycle.

In order to achieve the above objectives, one of the more broad aspects of the present invention is an automated 3D forming operating system comprising: a construction platform having a construction chamber having a construction material in the construction chamber; and a lifting mechanism for constructing the construction The chamber pushes up or down; a construction displacement platform; a printing module, the printing module is assembled with the complex inkjet head structure, and can be printed onto the construction chamber to complete the 3D solid model; An automated operating system, the system mainly comprising an automatic conveying device, the automatic conveying device is configured to construct two sides of the lifting mechanism at the bottom of the chamber for carrying and conveying the construction chamber into the lifting mechanism for 3D solid model forming operation.
