【摘要】：基于Delta并聯(lián)機械結(jié)構(gòu)相比于笛卡爾坐標系機械結(jié)構(gòu)的優(yōu)勢,并將其用于3D打印機的研發(fā)與設(shè)計,提出了一種基于Delta機構(gòu)、低成本、網(wǎng)絡(luò)化3D打印機設(shè)計方案。相比使用更加廣泛的笛卡爾坐標系3D打印機,Delta式3D打印機允許更大的打印體積和更快的打印速度。該打印機以STM32單片機作為核心控制器,以步進電動機作為驅(qū)動元件,驅(qū)動同步帶轉(zhuǎn)動,利用滑塊控制打印頭按照預(yù)定的軌跡行進。為減輕打印頭的重量,提高打印速度,采用遠程送料機構(gòu),并通過步進電動機送料,進行數(shù)字溫控,配合打印頭完成打印作業(yè)。為加快3D打印機推廣及使用,提出互聯(lián)網(wǎng)3D打印方案,通過配備Wi Fi模塊實現(xiàn)數(shù)據(jù)的無線傳輸與遠程控制,并增加了自動調(diào)平、斷電續(xù)打、斷絲檢測等功能,極大地增強了3D打印機使用的便利性。實踐表明該打印機具有運動平穩(wěn)、高速、高精度、成本低、易于控制等優(yōu)點。
[Abstract]:Based on the advantages of Delta parallel mechanical structure compared with the Cartesian coordinate system, and applied to the research and design of 3D printer, a design scheme of 3D printer based on Delta mechanism, low cost and network is proposed. More widely used Cartesian coordinate 3D printers than the Delta Type 3D printers allow larger print volume and faster printing speed. The printer uses STM32 single chip microcomputer as the core controller and stepping motor as the driving element to drive the synchronous band rotation. The slider is used to control the print head to travel according to the predetermined track. In order to reduce the weight of the printing head and improve the printing speed, the remote feeding mechanism was adopted, and the digital temperature control was carried out through the stepper motor to complete the printing operation with the printing head. In order to speed up the promotion and use of 3D printers, the Internet 3D printing scheme is put forward. The wireless transmission and remote control of data can be realized by using Wi Fi module, and the functions of automatic leveling, interrupting, wire breaking detection and so on are added. This greatly enhances the convenience of using 3D printers. Practice shows that the printer has the advantages of smooth motion, high speed, high precision, low cost and easy to control.
