[0002] Laser collimation refers to the process of focusing a laser beam to a very small point or line to ensure that the direction and geometry of the beam meet specific requirements. Its main functions include:

[0003] Precise positioning: Laser collimation can be used to precisely locate a target or measure the position of an object. Due to the high concentration of the laser beam, high-precision positioning can be achieved over a long distance.

[0004] Measurement and calibration: Laser alignment can be used to measure and calibrate a variety of equipment and systems, such as industrial machinery, optical equipment, and precision instruments. By accurately directing the laser beam to a specific location or reference point, precise measurements and adjustments can be made.

[0005] Lighting and Displays: Laser alignment can also be used in lighting and display applications. For example, in demonstrations, shows, or exhibitions, laser alignment can be used to create high-brightness, clear patterns or signs.

[0006] Communications and transmission: In optical communications and fiber optic transmission, laser alignment is used to ensure accurate transmission and reception of optical signals. By accurately focusing the laser beam onto the fiber input, the efficiency and reliability of data transmission can be maximized.

[0007] Scientific Research: In the field of scientific research, laser collimation is often used in laboratory experiments and research to explore various phenomena and principles in fields such as optics, physics, and engineering.

[0008] Overall, laser alignment plays a vital role in a wide variety of applications, enabling precise positioning, measurement, and transmission, as well as creating unique lighting and display effects.

[0009] Laser alignment in the prior art requires lenses, but when the lenses are placed on a lens holder, it is impossible to determine whether the lenses are installed or whether the installation position is correct. When the lenses are incorrectly installed or not installed, a series of problems will occur due to misalignment of the laser alignment. Utility Model Content

[0022] A device capable of detecting the position of a lens, comprising: a lens frame 1, a guide groove, a roller 2, a micro switch 3 and a connecting line 4;

[0023] In one embodiment, Figure 1 As shown, the lens frame 1 is installed in the guide groove, and the lens frame 1 can move in the guide groove. A groove is provided on the upper side of the lens frame 1. The roller 2 is installed on both sides of the lens frame 1 and is connected to the micro switch 3 through the connecting line 4. The roller 2 is controlled by the micro switch 3 to drive the lens frame 1 to move left and right in parallel.

[0024] In one embodiment, Figure 1 As shown, a collimating lens is installed on the lens frame 1.

[0025] In one embodiment, Figure 1 As shown, there are three connecting wires 4 on the micro switch 3, namely pin 1, pin 2 and pin 3. When the micro switch 3 is in the pop-up state, pin 1 and pin 2 are connected, and when the micro switch 3 is in the pressed state, pin 1 and pin 3 are connected.

[0026] In one embodiment, Figure 1 As shown, the roller 2 and the micro switch 3 are provided in two groups, which are respectively installed on both sides of the lens frame 1; each micro switch 3 controls one roller 2. .

[0027] Working principle: This device consists of a lens frame 1, a guide groove, a micro switch 3 and a connecting line 4. The lens to be detected has been installed on the lens frame 1. There is a groove at a designated position on the upper end of the lens frame 1; the lens frame 1 is installed in the guide groove, and the lens frame 1 can only move parallel to the left and right.

[0028] There are three connecting wires 4 on the micro switch 3, namely pin 1, pin 2 and pin 3. When the micro switch 3 is in the pop-up state, pin 1 and pin 2 are connected, and when the micro switch 3 is in the pressed state, pin 1 and pin 3 are connected. In the implementation process, when the lens frame 1 is installed to the correct position, the roller 2 of the upper micro switch 3 is just embedded in the groove. At this time, the micro switch 3 is in the pop-up state, and pin 1 is connected to pin 2; at this time, the roller 2 of the lower micro switch 3 is in the pressed state, and pin 1 is connected to pin 3. Use the connecting wire 4 to connect pin 2 of the upper micro switch 3 and the lower micro switch Pin 3 of switch 3 is connected, and pin 1 of upper and lower micro switches 3 is connected to line 4 as a signal for detection. When lens holder 1 is in the correct position, the signal line is in the on state; when lens holder 1 is moved left or right, that is, the lens position is incorrect, roller 2 of upper micro switch 3 is in the pressed state, and pins 1 and 2 are in the disconnected state. When there is no lens holder 1, roller 2 of lower micro switch 3 is in the pop-up state, and pins 1 and 3 are in the disconnected state. Both state signals are in the disconnected state, so whether the installation position of the lens is correct can be effectively detected.

[0029] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
