Step 1: Select the laser type of cleaning machines
1. Pulse laser: It can better control the heat input and prevent the substrate temperature from being too high or micro-melting. It is suitable for application scenarios with high precision, which need to strictly control the heating of the substrate and require the substrate to be non-destructive, such as the mold industry.
2. CW laser: It has a price advantage, the average laser power is higher, as well as the cleaning efficiency. However, the heat input of high-power CW lasers is greater, and the degree of damage to the substrate will also increase. It is widely used for some large steel structures, pipes, etc., due to the large volume and fast heat dissipation, the requirements for substrate damage are not high.
Step 2: Laser power selection of cleaning machines
|
|
Laser Power |
|
|
Pulse laser |
100-300W ①The laser is stable and the market usage is large ②Suitable for most mold industries, refurbishment of spare parts |
≥500W ①The price is higher and the market usage is smaller ②Suitable for rail and automobile industry ③Suitable for fine cleaning that requires high efficiency |
|
CW laser |
1000-2000W ①The laser is stable and cost-effective ②Meet the rust removal applications in most industries ③Suitable for cleaning large-scale pipeline industry, high cleaning |
≥3000W ①High power, large heat input, and large thermal impact on the substrate after cleaning ②Suitable for the cleaning of thick rust and paint layers in the shipbuilding industry |
Step 3: Select the cleaning head of cleaning machines
At present, there are two kinds of cleaning heads for laser cleaning machines: single wobble cleaning head and double wobble cleaning head.
|
Type |
Size & Structure |
Difference |
|
single wobble |
Small size and light weight one wobble lens |
①The cost is relatively low.
②Single cleaning track: straight line. ③ It is required to clean the moving speed evenly, and streaks are prone to appear. ④Low cleaning efficiency. |
|
double wobble |
large size and heavy weight two wobble lens |
①The cost is relatively high.
②Various cleaning trajectories: spiral, cross line, circle, square, etc. ③Easy cleaning operation and good performance for uniform cleaning shading. ④High cleaning efficiency. |
Single wobble cleaning track
Double wobble cleaning track
Step 4: Selection of other aspects of cleaning machines
|
Operation Mode |
Hand-held cleaning
① The cleaning head is required to be light ② The power of the cleaning machine is not easy to be too high, |
Automatic cleaning
①High cleaning efficiency requirements, suitable for high-power laser cleaning machines ② Long cleaning time and high stability requirements |
|
Cleaning Range (optical fiber length) |
The length of the optical fiber cable of the laser affects the scope of the cleaning area. The current standard cable length of the laser cleaning machine is as follows:
1. Pulse laser: 5m (100-300W), 10m (≥500W) 2. CW laser: 10-15m (1000-3000W) (If a larger cleaning range is required, it needs to be explained in advance, and the cable length of the laser cleaning machine can be customized) |
