[0002] Advanced sensors have changed the use of machine production in the manufacturing industry, providing higher precision and more intelligent perception. With the advent of the Industrial 4.0 era, sensors, as an indispensable and important role, will surely usher in rapid development. As the market places higher demands on sensor measurement accuracy, response speed, and reliability, the laser needle sensor adopts a dustproof and waterproof design, with fast and accurate feedback, high accuracy, simple functions, easy operation, and is not easily affected by ambient light. At present, laser needle sensors can adopt non-contact detection. When performing irregular inspections, they need to be fixed in a certain place. For this reason, the utility model designs a laser needle sensor that is easy to fix. Utility Model Content

[0018] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1

[0020] Refer to the instruction manual Figure 1-6 A laser needle sensor of this embodiment includes a sensor body 1, a hidden hole 7 is opened at the bottom end of the sensor body 1, and a concealable fixing structure 2 is arranged inside the hidden hole 7.

[0021] The laser needle alignment sensor provided in this embodiment is HPS-LCB02, which is a high-precision laser needle alignment sensor used for positioning in industrial occasions. It can realize absolute position correction and zero point reset along the three dimensions of the sensor X, Y, and Z, and has good impact resistance and durability.

[0022] HPS-LCB02 has ultra-high measurement accuracy. The ultra-small light spot of 30um enables the repeatability to reach 0.01mm. HPS-LCB02 has ultra-fast response time and the detection frequency is up to 2kHz.

[0023] HPS-LCB02 can not only calibrate two axes at the same time, but also calibrate three coordinates at the same time. The X, Y and Z axes can be precisely positioned at the same time. There is no need to calibrate the product after installation, and all signal communications are concentrated in one interface, which makes wiring simple and easy to install.

[0024] HPS-LCB02 has a built-in background light compensation algorithm, which can resist strong light interference and improve the reliability of the sensor. The whole body can achieve IP67 industrial-grade protection. It adopts IP67 protection grade design, which is dustproof, waterproof, stable and reliable.

[0025] The core of the HPS-LCB02 laser needle sensor automatic calibration is the center search algorithm. A two-dimensional coordinate system XY is formed by two opposing light paths. The robot guides the object to be calibrated to search near the center of the laser needle sensor, and then guides the object to be calibrated to move from right to left along the Y direction. When the object to be calibrated first contacts the laser beam, it is recorded as Y1, and the position when the object to be calibrated just leaves is recorded as Y2. The center position in the Y direction is the coordinate of (Y1+Y2) / 2. Similarly, the center position of the X axis can be found, which is (X1+X2) / 2. Figure 6 After locating the center point of XY, lift it up. When two laser beams disappear or appear at the same time, it is the zero point of Z axis. Combine the above to find the center zero point.

[0026] As a preferred technical solution of the present application, the fixed structure 2 includes a mounting plate 3, the mounting plate 3 is located at the bottom end of the sensor body 1, a spring 8 is provided at the top of the mounting plate 3, positioning holes 6 are provided on both sides of the spring 8, two grooves are provided inside the sensor body 1, both grooves are connected to the inside of the spring 8, a spring 2 9 is provided inside the groove, one end of the spring 2 9 extends into the inside of the spring 1 8, and a blocking member 10 is provided at one end of the spring 2 9.

[0027] As a preferred technical solution of the present application, the mounting plate 3 is provided with a plurality of penetrating mounting holes 5 .

[0028] As a preferred technical solution of the present application, a convenient hole 4 is opened at the bottom end of the mounting plate 3, and the convenient hole 4 is L-shaped.

[0029] As a preferred technical solution of the present application, the blocking member 10 is spherical, and the outer diameter of the blocking member 10 matches the inner diameter of the positioning hole 6 .

[0030] Put your finger into the convenient hole 4. Since the convenient hole 4 is L-shaped, it is convenient to pull the mounting plate 3 out of the blind hole 7. When the mounting plate 3 is pulled outward, the spring 8 connected to its top end is stretched. At this time, the blocking member 10 located inside the positioning hole 6 gradually leaves the positioning hole 6 until it returns to the inside of the groove. At this time, the mounting plate 3 is pulled out. Figure 1 and Figure 2 At this time, you only need to insert a bolt into one of the mounting holes 5 to find the mounting position, so that you can easily perform subsequent installation operations;

[0031] Take out the bolt from the mounting hole 5, push the mounting plate 3 into the blind hole 7, and the spring 29 contracts to drive the blocking member 10 to move toward the inside of the groove until the blocking member 10 is aligned with the positioning hole 6. At this time, the spring 29 extends, so that the blocking member 10 is inserted into the positioning hole 6. At this time, the mounting plate 3 is hidden inside the sensor body, which is suitable for situations where regular inspection is not required (just a quick inspection once).

[0032] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
