The principle of the toothbrush hair transplanting machine. The main drive shaft and four servo drive shaft systems form the transmission structure of the high-speed toothbrush hair transplanting machine. The four servo axes are the horizontal X axis, the vertical Y axis, the flap Z axis and the hair-changing U axis. The XY axis coordinates determine the position of the toothbrush hole, the Z axis plays the role of changing to the next toothbrush, and the U axis plays the role of changing the hair color of the toothbrush. When the spindle motor is running, the four electronically controlled servo axes will follow. When the spindle stops, the other four axes will follow and stop. The rotation speed of the spindle determines the speed of hair transplantation, and the response of the four servo axes requires coordinated driving, otherwise hair removal or uneven hair will occur. The application of high-precision electrical servo control can achieve a hair transplanting speed of 1,000 times/minute, and can achieve jump-hole hair transplantation.
