How Much Do You Know About Line Laser Module?

Line Laser Module is a device that emits a linear laser spot. It is often used in various occasions that require precise linear positioning: machine vision positioning, scanning, decoration assistance, cutting and cutting assistance, etc. It uses a laser beam to scan the surface of the item, forming a remarkable line of light on the surface of the item, helping workers quickly and accurately identify the location of the item, and achieving efficient production or distribution operations.

We often refer to One Line Lasers as Line Laser Module, a module (or module) refers to a specific functional component composed of several basic functional components, and Line Laser Module is a light source component of a laser diode, a wave Composed of optical lenses such as mirrors and Powells, this is a functional module that converts point lasers into line lasers. You can install the line laser at any position and form an obvious line on the wall, floor or ceiling. Laser, thus providing precise assistance for work in all directions.

Principle

The principle of a word-line laser involves the processes of laser emission, diffusion, reflection and focusing.

1. Launch: use laser diodes (semiconductor lasers) to emit initial laser light. This type of laser diode can produce high-precision, single-color point-like laser light.

2. Diffusion: The laser passes through an optical element called a beam expander, which expands it from a small, high-intensity spot to a larger, low-intensity beam. This process ensures uniform light intensity while reducing possible eye damage from the beam.

3. Reflection: The diffused laser passes through a specially designed mirror system, so that the laser beam is dispersed into many sub-beams, and the optical path of these sub-beams is at a certain angle. The exact shape depends on the design of the mirror system.

4. Focusing: These sub-beams are refocused into a laser line through a lens.

Line Laser Module Laser Color

The commonly used laser wavelengths of line lasers are 450nm, 520nm, 650nm, 830nm, 450nm is blue laser, 520nm is green laser, 650nm is red laser, 830nm is infrared laser, the higher the laser power, the brighter the laser, the laser can be observed at greater distances.

Basic Parameters of Line Laser Module

1. Divergence angle / lens angle: 130°

2. Power supply: 150mw 3.5V

3. Wavelength: support multi-wavelength

4. Use time: more than 10,000 hours of continuous work

According to different distance applications, the divergence angle of the line laser that projects the spot will be adjusted accordingly. In most cases, we can adjust the size of the spot through the front knob of the line laser to better obtain the right spot at different distances. The inline laser spot size and dimension length.

Structure of Line Laser Module

The internal structure of a word-line laser can be split into:

1. The main frame plays the role of fixing the internal optical devices and encapsulating and protecting them.

2. Laser diodes, which generate laser light through stimulated radiation, generate laser light through electricity.

3. The optical element (lens) performs secondary collimation on the laser emitted by the laser diode, and reshape the deflected beam into a line spot.

Advantage

1. Good directionality

The light spot is a straight laser spot, which is straight enough and not affected by the user's proficiency and other factors.

2. Concentrated light

The high visibility is convenient for us to use human eyes for long-distance observation. Of course, the accuracy of observation with sensors is higher.

3. No contact

No contact will not interfere with the measured object, and there will be no unnecessary effects. Of course, pay attention to the surface color of the object projected by the line laser. The laser color and the same color of the object are easy to be unclear.

The Function of The Line Laser Transmitter:

1. Auxiliary positioning function

(1) Processing procedures such as cutting, cutting, and folding often require quick response and accurate processing, so a non-contact reminder tool that does not hinder observation and operation is required. The straight-line laser transmitter can be directly installed on the preset bracket (also You can use the universal bracket provided by the manufacturer to install), and manually adjust the projected spot size to provide accurate auxiliary positioning of the branch line.

(2) Fengshui compass, this is probably not expected by everyone. In fact, the combination of laser has developed into a laser automatic compass, which can accurately locate and is not affected by magnetic fields.

2. Measuring function

(1) Use a one-line laser transmitter to emit a one-line laser light source, cooperate with the sensor and use the triangulation method to build a machine vision system, and check the length, width, height, inner diameter, outer diameter, and gaps of the product quality inspection links of the production line. Parameter measurement.

(2) The measurement of potholes on the road surface also uses the triangulation method. It is installed at the rear of the measuring vehicle and follows the vehicle to measure the depth of the potholes and depressions on the ground to quickly measure the road surface that needs to be repaired.

3. Scanning function

(1) The scanning function of the one-line laser transmitter can not but mention the sweeping robot. In terms of usage, it is a lot. The one-line laser transmitter is used as the obstacle avoidance radar laser source of the sweeping robot, while ensuring the scanning quality. It also has a good cost control advantage.

(2) At the same time, it can also be used as a light source for some detection scanners to enhance the imaging effect of 3D laser scanning, obtain more different scanning information, and facilitate the synthesis of information to build 3D models.

4. Warning Function

Providing two cool one-line lasers on both sides of the bicycle can not only provide a cool visual effect, but also remind the car coming from behind, which is very conspicuous, especially in dark environments.

The Line Laser Module has more advantages than the traditional level, line hanging and other tools in use, it can provide higher accuracy and is easy to operate. The line laser is easy and convenient to use, the laser stripes are fine, the laser distribution is uniform, and the edges are clear. In addition to being used as a traditional manual auxiliary tool, it has also been developed into machine vision automation. Lanyu Laser can provide customers with different wavelengths and different powers. line laser products. It has the advantages of easy integration, high reliability, and convenient use. It can be combined with various machine vision systems to realize highly automated machine vision applications.
