Three-dimensional surface printing system

The invention relates to a three-dimensional surface printing system, in particular to a microprocessor, a nozzle moving component, a nozzle pointing component, a nozzle printing component and an object positioning component, so as to form a three-dimensional surface printing of different colors on a stacked material. Coloring function.

In many industrial fields, before the mass production of a product, it is necessary to make a solid model, which can be reduced in size or the same size, for evaluation including appearance shape, component configuration of components, or other related verification, such as electronics. Wind tunnel testing of the product's casing and car.

Traditionally, the mold is first made, and the mold is filled with a suitable filler such as plastic to fill the mold, and then the mold is released to obtain the desired solid model, and if the appearance, shape, size, If the hole or slotting position is not satisfactory, it can be achieved by modifying the mold. However, the production of the mold is quite time-consuming and laborious, and the price is expensive. Moreover, the modification of the mold is achieved by using the cutting method, the process is quite complicated and limited, and it is difficult to modify it at will, and often the actual requirements are not met.

In recent years, with the rapid development and maturity of multi-layer manufacturing technology, the laminating machine has been able to produce prototype bodies with arbitrarily complex shapes or fine structures, which can completely get rid of the limitations of conventional cutting and overcome the processing and manufacturing models. Defects. Therefore, the laminated manufacturing technology has been practically applied to various industries, and both the aviation industry and the automobile industry have examples of using solid layer manufacturing machines to make solid models or parts.

In general, the main principle of a laminate manufacturing machine is to use the concept of layered stacking, that is, when a three-dimensional (3 dimensional, 3D) object is cut in a certain direction, a piece of thin sheet is formed, which can be thinned. Think of a two-dimensional (2D) object, and after stacking all the sheets in sequence, you can create a 3D solid model, where the sequential stacking is one. The so-called 3D printing.

The current multi-layer manufacturing machine is quite mature in printing a single color solid model, but in practice, a multi-layer manufacturing machine with a multi-color stereo model printing function is required, but in fact, the color that can be exhibited in the layer-manufactured entity is still Not enough, the reason is that when the solid model is printed, the stacked materials are stacked one by one, so the color of the stacked material itself determines the color of the solid model, and although the stacked materials of different colors can be added, the solid model shows different Color, but you need to change the stacking materials of different colors when stacking the model, and there are not many materials that can be used on the laminating machine. To stack different materials in different colors on the same laminating machine, not only increase the cost, It also increases the mechanism and time required to replace materials. That is to say, it is possible to stack materials of various colors, and because there are not many colors available, the manufacturing of the layers is monotonous in the performance of the color. In addition, when a plurality of stacked materials of different colors are prepared, the overall system volume is too large, and the less used color materials are wasted due to storage problems.

Therefore, there is a need for a new three-dimensional surface printing system, which mainly uses an inkjet nozzle on a conventional laminated manufacturing machine, and can spray various dyes or pigments on the stacked materials to realize the color printing function, which is equivalent to the printing table. The nozzle of the machine is used to solve the above problems of the conventional technology.

The main object of the present invention is to provide a three-dimensional surface printing system, which mainly comprises a microprocessor, a nozzle moving component, a nozzle pointing component, a nozzle printing component and an object positioning component, which are used for forming a color in combination with a laminated manufacturing component. A multi-layer printing machine with a three-dimensional printing function.

The microprocessor sends a control command to control the nozzle moving assembly, the head pointing assembly, the object positioning assembly, and the printhead printing assembly, wherein the head moving assembly can move the printhead assembly to a desired spatial position on the carrying object, and The nozzle pointing component adjusts the nozzle printing assembly, and the object positioning assembly can move and rotate the carrying object to an appropriate position and angle.

Specifically, the printhead printing assembly may comprise a plurality of inkjet printheads, each of the inkjet printheads comprising a nozzle and a pigment cartridge, and each nozzle is coupled to a corresponding pigment cartridge, wherein the pigment contains a dye of a specific color Or paint, and the microprocessor sprays the dye or paint by controlling the direction in which the nozzle is ejected.

In particular, the nozzle moving assembly of the present invention can appropriately move the nozzle printing assembly in conjunction with the laminated manufacturing assembly, while adjusting the ejection direction of the nozzle by the nozzle pointing assembly. Therefore, when the laminated manufacturing assembly ejects the stacked material, the nozzle printing assembly of the present invention The nozzle sprays the dye or coating onto the stacked material such that the surface of the stacked material has a color for coloring purposes.

Furthermore, the microprocessor of the present invention can control the amount of dye or paint sprayed by each ink jet head to form different colors, for example, the head print assembly can include a magenta ink jet head, a yellow ink jet head, and a cyan ink jet. Sprinklers, respectively, spray magenta, yellow and cyan dyes or coatings, and mix different proportions of magenta, yellow and cyan, you can adjust the color of different color scales, such as the most basic 256 color or even million colors The color above the order.

The invention may further comprise a 3D scanning component for rotating the target object with the object positioning member disposed on the carrying object, and rotating the object to rotate the target object to perform 3D scanning to generate 3D scanning information of the target object, wherein the 3D scanning is performed. The information includes the required spatial location as described above, and the microprocessor of the present invention can be provided to control the nozzle moving assembly, the head pointing assembly, the printhead printing assembly, and the object positioning assembly, and each of the ink jet heads of the printhead assembly is targeted The object sprays a dye or pigment to achieve a coloring function. That is, the 3D scanning assembly of the present invention can further provide for post-production of the finished article.

Since the ink jet head of the present invention is an ink jet head similar to a general printer, various colors can be sprayed on the stacked material, so that only a stacking material which is easy to color can be disposed, and the laminated manufacturing machine can be used. Stacked solid models are added to various colors without the use of stacked materials of different colors. In addition, the price of printer ink is much cheaper than stacked materials of different colors, so it is quite cost-effective and can achieve better coloring effect.

In general, the present invention can use the inkjet nozzle to spray the color of each layer of the stacking material when stacking the vehicle stacking materials layer by layer in the layering manufacturing machine, or, instead of spraying the color of each layer of the stacking material, When the solid model is completed, the coloring is performed, which makes the use more flexible, which can meet different practical applications and increase the utilization.
