[0002] Laser measurement technology is an advanced technology that measures parameters such as distance, displacement, and velocity based on the characteristics of lasers. It utilizes the high directionality, high monochromaticity, and high brightness of lasers to achieve precise measurements by emitting laser beams and receiving reflected light. In a laser measurement system, the laser receiver plate is a key component. When a laser beam strikes a target object and reflects back, the laser receiver plate is responsible for capturing these reflected light signals. It is typically made of optoelectronic materials sensitive to laser wavelengths and can efficiently convert the received light signals into electrical signals. The receiver plate's sensitivity and response speed to laser signals directly affect the accuracy and real-time performance of the measurement. Advanced laser receiver plates also possess advantages such as strong anti-interference capabilities and good stability, enabling them to work accurately in complex environments. Thanks to the outstanding performance of components such as laser receiver plates, laser measurement technology is widely used in industrial manufacturing, construction engineering, aerospace, and other fields, providing strong support for precise measurement and quality control in various industries.
[0003] In existing conventional laser receivers, the lens and the light receiving plate are mounted by a fixed bracket. The distance and angle between the two must be strictly calibrated during assembly. If there are assembly errors, offsets, tilts, excessive material tolerances, poor optical consistency, etc., the light spot will deviate from the sensitive area of the receiving plate, reducing measurement accuracy and increasing the product defect rate.

Detailed Implementation
[0015] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.
[0016] Example 1: This embodiment of the present invention provides an adjustable laser bracket light receiving plate device, such as... Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, it includes a base 1, a movable component 2 is provided on the top of the base 1, a receiving plate 3 is provided on the top of the movable component 2, an adjusting component 4 is provided on the top of the receiving plate 3, and a lens 5 is provided on the top of the adjusting component 4.The adjusting component 4 includes a screw groove 401, which is located inside the receiving plate 3. An adjusting screw 402 is threaded into the screw groove 401. A shock-absorbing pad 403 is embedded in the top of the receiving plate 3, and a support spring 404 is fixedly connected to the top of the shock-absorbing pad 403. A bracket 405 is fitted onto the top of the support spring 404. The bracket 405 forms a threaded structure with the receiving plate 3 via the adjusting screw 402. The outer diameter of the adjusting screw 402 matches the inner diameter of the screw groove 401 in the receiving plate 3. One end of the adjusting screw 402 passes through the bracket 405 and extends into the screw groove 401 for fastening, strengthening the connection between the bracket 405 and the adjusting screw 402, allowing the adjusting screw 402 to... Rotating within the screw groove 401 in the receiving plate 3 allows for angle adjustment of the bracket 405. The damping pad 403, via a support spring 404, forms an elastic structure with the bracket 405. The support spring 404 is positioned between the damping pad 403 and the bracket 405, facilitating its placement and allowing the bracket 405 to be stably mounted above the receiving plate 3 under its support. This facilitates adjustment and support of the bracket 405. An mounting pad 406 is fixedly connected internally to the bracket 405. An internal thread 407 is formed inside the bracket 405, connecting to a housing 408. An external thread 409 is formed on the outer wall of the housing 408. The internal thread 407 and the outer shell 408 form a threaded structure, and the inner diameter of the internal thread 407 matches the outer diameter of the external thread 409 on the outer shell 408. The internal thread 407 and the external thread 409 are fitted together, strengthening the connection between the outer shell 408 and the bracket 405. This allows the outer shell 408 to be fastened and installed within the internal thread 407 of the bracket 405 by the external thread 409. A shock-absorbing pad 403 is placed between the receiving plate 3 and the bracket 405 to absorb vibration and maintain adjustment stability. During adjustment, the adjusting screw 402 can be rotated within the screw groove 401, allowing the adjusting screw to rotate. The height of screw 402 can be adjusted along the screw groove 401, which in turn can adjust the height of one corner of the bracket 405. Supported by the spring 404 at the top of the receiving plate 3, the stability during adjustment is improved. Four adjusting screws 402 are installed at the four corners of the bracket 405, supporting X / Y / Z three-axis displacement adjustment, allowing the light spot to be precisely projected onto the center of the receiving plate 3. Furthermore, by rotating the outer casing 408, which rotates out from the internal thread 407 within the bracket 405 via the external thread 409, it is easy to loosen, disassemble, and replace different lenses 5. This modular design facilitates maintenance and replacement, improving the practicality of the device.
[0017] Example 2: In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the moving component 2 includes a motor 201, which is fixed to the top of the base 1. The output shaft of the motor 201 is fixedly connected to a lead screw 202 via a coupling. A guide sleeve 203 is threadedly connected to the outer wall of the lead screw 202. The motor 201 forms a threaded structure with the lead screw 202 and the guide sleeve 203. The outer diameter of the lead screw 202 matches the inner diameter of the guide sleeve 203, and the outer wall of the lead screw 202 fits snugly against the inner wall of the guide sleeve 203, enhancing the connection between the motor 201 and the lead screw 202. This allows the motor 201 to rotate the lead screw 202 within the guide sleeve 203, enabling the receiving plate 3 to adjust its position against the outer wall of the lead screw 202 using the guide sleeve 203 at its bottom. A sliding sleeve 204 is fixedly connected to the bottom of the receiving plate 3. The receiving plate 3 is slidably connected to the slide rail 205. The receiving plate 3 forms a sliding structure with the slide rail 205 through the slide sleeve 204. The inner diameter of the slide sleeve 204 matches the outer diameter of the slide rail 205, and the inner wall of the slide sleeve 204 fits against the outer wall of the slide rail 205, which strengthens the connection between the receiving plate 3 and the slide sleeve 204. This allows the receiving plate 3 to slide along the outer wall of the slide rail 205 by relying on the slide sleeve 204. By starting the motor 201, the motor 201 can drive the lead screw 202 to rotate in the guide sleeve 203, allowing the receiving plate 3 to slide along the outer wall of the slide rail 205 by relying on the bottom slide sleeve 204. This allows for position adjustment of the receiving plate 3. By adjusting the position of the receiving plate 3, the maximum amplitude light intensity reception effect is improved, meeting people's daily use needs.
[0018] Working principle: By setting a shock-absorbing pad 403 between the receiving plate 3 and the bracket 405, vibration can be absorbed and adjustment stability can be maintained. During adjustment, the adjusting screw 402 can be rotated within the screw groove 401, allowing for height adjustment along the groove. This, in turn, adjusts the height of one corner of the bracket 405. Supported by the spring 404 at the top of the receiving plate 3, the stability during adjustment is improved. Four adjusting screws 402 installed at the four corners of the bracket 405 support X / Y / Z three-axis displacement adjustment, ensuring precise projection of the light spot onto the center of the receiving plate 3. Furthermore... By rotating the outer casing 408, which rotates out of the internal thread 407 within the bracket 405 via the external external thread 409, it is easy to loosen, disassemble, and replace different lenses 5. This modular design facilitates maintenance and replacement, improving the practicality of the device. Furthermore, by starting the motor 201, the motor 201 can drive the lead screw 202 to rotate within the guide sleeve 203, allowing the receiving plate 3 to slide along the outer wall of the slide rail 205 via the bottom sliding sleeve 204. This allows for position adjustment of the receiving plate 3, thereby improving the maximum amplitude light intensity reception effect and meeting people's daily needs.
