Three-axis high-speed stepper motor control card is used in laser rapid prototyping machine
Laser rapid prototyping is a new technology in mold manufacturing and has been widely used abroad. The laser rapid prototyping machine adopts the principle of material accumulation. The laser scanner continuously scans the surface of the liquid photosensitive resin according to the layered data under the control of the computer. The liquid photosensitive resin is solidified by laser irradiation, and the layer is cured. After curing, the workpiece is moved down a precise distance, and then the next layer is scanned, and the adjacent layers are reliably bonded. Thus, the product prototype can be accurately fabricated without any complexity. , truly achieve moldless manufacturing. It has the characteristics of fast forming speed, high forming precision, good surface quality, simple post-processing and time saving, and short model manufacturing cycle. Applicable to all manufacturing and research industries such as automobiles, home appliances, aviation, ships, medical, etc., with broad application prospects.
It can be seen from the above that the control of the laser forming machine can be divided into two parts, one part is the two-dimensional scanning control of the laser beam, and the other part is the control of the liquid level leveling, the resin liquid level control and the pallet lifting, the latter tradition The processing method is directly controlled by the stepping motor through the PC, so that not only a large amount of host CPU resources are occupied, but also the response is not timely. Advantech's newly developed PCL-839 three-axis high-speed stepper motor control card, due to the built-in CPU, can realize motion control and interpolation algorithms to form the upper and lower computer structure, which greatly reduces the burden on the host and realizes fast motion control.
