Description
本案係關於一種噴頭清潔模組,尤指一種用於清潔三維快速成型裝置之噴頭的噴頭清潔模組。The present invention relates to a nozzle cleaning module, and more particularly to a nozzle cleaning module for cleaning a nozzle of a three-dimensional rapid prototyping device.
近年來隨著個人電腦的普及與網際網路的快速發展,三維快速成型裝置已經漸漸普及。對一般的使用者而言,一台三維快速成型裝置就足以應付各種三維成型物品之列印的需求。其中,噴墨頭的結構設計更是攸關噴墨印表機所產生的成型物品質的重要影響因素。在一般三維噴墨列印技術中,其係利用噴頭將墨水或膠合劑噴印於成型材料上,例如陶瓷粉末等等,並透過層層推疊的噴印方式而成型出三維成型物,然而,在噴印過程中,墨水噴頭周圍會容易堆積使用後殘餘之墨滴與受粉塵覆蓋,膠合劑噴頭亦可能堆積膠合劑殘餘物、粉塵或結晶物,如此將會造成噴頭噴孔阻塞,進而影響到列印品質,造成墨水及膠合劑噴印不均勻、噴頭阻塞或是噴墨顏色失準等問題,大大降低了噴頭之壽命。因此為了保持噴頭的清潔以延長噴墨頭的使用壽命,以及維持列印品質,噴墨頭馬達理所當然的是噴墨印表機中不可或缺的一項裝置。In recent years, with the popularization of personal computers and the rapid development of the Internet, three-dimensional rapid prototyping devices have gradually become popular. For a typical user, a three-dimensional rapid prototyping device is sufficient for the printing of various three-dimensional shaped articles. Among them, the structural design of the inkjet head is an important factor affecting the quality of the molded product produced by the inkjet printer. In the general three-dimensional inkjet printing technology, a nozzle is used to spray ink or glue onto a molding material, such as ceramic powder, etc., and a three-dimensional molding is formed by layer-by-layer printing. During the printing process, the ink droplets are easily accumulated around the ink droplets and covered by the dust. The glue nozzle may also accumulate glue residue, dust or crystals, which will cause the nozzle nozzle to block. Affects printing quality, causing uneven printing of inks and adhesives, blockage of nozzles, or misalignment of inkjet colors, greatly reducing the life of the nozzles. Therefore, in order to keep the head clean, to extend the life of the head, and to maintain print quality, the head motor is of course an indispensable device in an ink jet printer.
雖然習知的三維快速成型裝置中,通常皆設有噴墨頭馬達,然而,習知的噴墨頭馬達多半透過刮板以刮除殘餘物,然而此種清潔方式效果有限,無法完全刮除殘餘物,且容易造成噴頭的損傷,導致成本提高。Although conventional three-dimensional rapid prototyping devices are generally provided with an inkjet head motor, conventional inkjet head motors mostly pass through the squeegee to scrape the residue, but this cleaning method has limited effect and cannot be completely scraped off. Residues, and easily cause damage to the nozzle, resulting in increased costs.
因此,如何發展一種可清潔噴頭使用後之殘餘墨水、堆積的粉塵或結晶物,以減少噴頭噴孔阻塞機會,增加噴頭壽命及增進三維成型物之品質之噴頭清潔模組,實為目前迫切需要解決之問題。Therefore, how to develop a nozzle cleaning module that can clean the residual ink, accumulated dust or crystals after use of the nozzle to reduce the nozzle clogging opportunity, increase the life of the nozzle and improve the quality of the three-dimensional molded product is urgently needed.

As shown in FIG. 3A , the two ink cartridges 11 of the embodiment are arranged on the carrier 14 and are reciprocatingly displaced. For three-dimensional printing, the X-axis directions of the inkjet heads 111 of the two ink cartridges 11 respectively correspond to one squeegee 20, and the sponge 23 portion of the nozzle cleaning module 2 protrudes from the surface of the susceptor 21, and Above the construction platform 13, the squeegee 20 is a structure in which the surface of the pedestal 21 is extended upwardly. The squeegee 20 protrudes from the top surface of the pedestal 21 and is adjacent to one side of the sponge 23, so that the carrier When the ink of the 14 is reciprocated in the X-axis direction by the displacement mechanism 12, the cleaning liquid is sprayed by the conduit 24 to clean the blade 20, so that the surface of the blade 20 is kept clean and non-stained; As shown, the carrier 14 is moved to the left direction so that the inkjet head 111 of the ink cartridge 11 abuts against the squeegee 20, and the carrier 14 is continuously moved to the left direction, so that the squeegee 20 is scraped off the inkjet head 111. Residual crystals, dust and ink, and when the carrier 14 is moved further to the right, the squeegee 20 can scrape off the remaining knot on the inkjet head 111 , dust and ink; as shown in FIG. 3C, when the carrier 14 moves to the right to reach the inkjet head 111 against the sponge 23, the squeegee 20 can still spray the cleaning liquid through the conduit 24 to clean the squeegee 20, thus When the next cleaning is performed, the surface of the squeegee 20 is kept free from contamination to maintain the optimum scraping operation, and when the sponge 23 rubs the ink jet head 111 of the ink cartridge 11, the sponge 23 on the carrier shaft 22 is subjected to the ink jet head 111. Move to the right position, and then roll it autonomously, so that the entire circumference of the sponge 23 can be adsorbed and removed to remove the residual crystals, dust and ink from the two inkjet heads 111, and the second cleaning operation is achieved. When the ink jet head 111 of the 11 leaves the contact sponge 23, the surface of the ink jet head 111 is free from water stains, and the absolute cleanliness is achieved, thereby achieving an optimal cleaning effect, thereby preventing the ink jet head 111 from being clogged and increasing the life of the ink jet 11 It can also improve the quality of three-dimensional molded products. In the present embodiment, the cleaning liquid system is water, but is not limited thereto. In other embodiments of the present invention, the cleaning liquid may be an organic solvent, so that the residual ink of the inkjet head 111 can be more completely removed, but not limited thereto. In other embodiments of the present invention, the nozzle cleaning module 2 further includes a plurality of carrier shafts 22, and are disposed in the recessed positioning slots 21a, so that a plurality of sponges 23 are disposed thereon to make the inkjet heads 111 transparent. More sponges 23 are cleaned to enhance the cleaning effect.

When the ink cartridge 11 is displaced above and in contact with the sponge 23 of the head cleaning module 2, the driving device 25 is driven. The drive carrier shaft 22 and the sponge 23 are rotated in the reverse direction, so that the sponge 23 quickly absorbs most of the crystals, residual ink and dust on the inkjet head 111 of the ink cartridge 11, and improves the cleaning effect.
綜上所述,本案之噴頭清潔模組係應用於三維快速成型裝置中,並透過導管噴出清潔液體清潔刮板,以保持刮板表面不沾汙維持最佳刮除狀態,當噴頭結構位移置噴頭清潔模組上方時,使海綿對噴墨頭摩擦清潔,搭配刮板對噴墨頭進行髒污刮除作業,以清除噴墨頭使用後之殘餘墨水、堆積的粉塵或結晶物,進而避免噴墨頭產生阻塞的情況,並增加噴墨頭壽命,提升三維成型物之品質。In summary, the nozzle cleaning module of the present invention is applied to a three-dimensional rapid prototyping device, and a cleaning liquid cleaning blade is sprayed through the conduit to keep the surface of the squeegee non-staining to maintain an optimal scraping state, and when the nozzle structure is displaced When the nozzle cleaning module is above, the sponge is rubbed and cleaned by the inkjet head, and the inkjet head is scraped with the scraper to remove the residual ink, accumulated dust or crystals after the inkjet head is used, thereby avoiding The ink jet head generates a blockage condition and increases the life of the ink jet head to improve the quality of the three-dimensional molded product.
