Strengthen the heat dissipation of the scanner, add the blower and the induced draft fan; in combination with the stop motor, check the contact pressure of the moving and static contacts, replace them if necessary, and replace the fatigued contact springs. Increase the research of internal temperature measurement technology of scanners, and apply new technologies such as wireless temperature measurement to solve the problem of difficult temperature measurement. This article will introduce you to the 3D laser scanner.
The most effective way to increase the power efficiency of your scanner is to use a switching power supply. The scanner power supply uses the principle of high frequency conversion to achieve voltage regulation and voltage regulation by changing the pulse width or pulse frequency on the power output tube. The scanner power tube operates in the on-off state, reducing power consumption and reducing efficiency. Scanner power supplies come in a variety of topologies, with scanner power supplies without power-frequency transformers being the most attractive, not only efficient, but also small in size and weight. However, this scanner power supply is only suitable for applications where the output voltage is fixed or the range of variation is small.
The scanner regulator is directly rectified to obtain high voltage DC. The scanner adjusts the time ratio of the on/off of the switch tube by the high frequency oscillator to adjust the output of a certain voltage. The scanner power supply circuit is divided into two types: series type and parallel type. The advantage of the scanner's regulated power supply is its high efficiency, because the transistor itself consumes very little power in the switching state, can reach 70-80% or higher, and does not need to use a step-down transformer to assist the operation, the scanner output Because the transformer is working at high frequencies, its power is much smaller than the 50 Hz power frequency transformer. Therefore, the scanner power supply circuit is small and light, and can work normally in a large voltage range.
With the continuous development of micro-electro-mechanical technology, the continuous maturity of technology, the continuous reduction of prices, and the increasing application fields, miniaturization is one of the development trends of future scanners. Microscanners will not only have the functionality of traditional scanners, but also play a unique role in automation technology, aerospace, military, biotechnology, and medical fields.
