Description

Technical Field

[0001] This application relates to the field of photoelectric measurement devices, and more particularly to a device for detecting the adaptability of a laser displacement sensor to a highly reflective tilted surface. Background Technology

[0002] Laser displacement sensors are non-contact precision measurement devices based on optical principles. They accurately calculate parameters such as displacement, thickness, and shape of a target object by emitting a laser beam and receiving the reflected light signal. With the rapid development of industrial automation, intelligent manufacturing, and precision manufacturing, laser displacement sensors have become one of the core technologies for modern industrial inspection and quality control due to their advantages such as high precision (down to sub-micron level), high speed (kHz-level sampling rate), and non-contact measurement. Currently, laser displacement sensors are widely used in automotive manufacturing, 3C electronics, semiconductors, new energy (lithium batteries, photovoltaics), aerospace, and other fields. In the future, with the development of MEMS lasers, AI compensation algorithms, and embedded systems, laser displacement sensors will further evolve towards miniaturization, intelligence, and high integration, providing stronger technical support for precision manufacturing and automated inspection. However, laser displacement sensors have the following problems in application: they are prone to specular reflection, the laser cannot return to the receiver, and the laser path must remain perpendicular to the surface of the measured object. Therefore, performance evaluation of laser displacement sensors is necessary, but currently there is no dedicated measurement device for performance evaluation, making performance evaluation of laser displacement sensors impossible. Utility Model Content

[0003] The main objective of this application is to provide a device for detecting the adaptability of a laser displacement sensor on a highly reflective tilted surface, aiming to solve the problem that the existing technology cannot achieve performance evaluation of laser displacement sensors.

[0004] To achieve the above objectives, this application provides a device for detecting the adaptability of a laser displacement sensor on a highly reflective inclined surface, comprising: a base, wherein a first support and a second support are sequentially arranged on the base along a first direction; both the first support and the second support are perpendicular to the first base; the first support is movably connected to the base and can move along the base in the first direction; a first disk and a second disk are symmetrically fixed at both ends of the second support, a central shaft is rotatably connected between the first disk and the second disk, and one end of the central shaft passes through the first disk and is perpendicularly connected to a blade; a clamp for holding the object to be measured is provided on the central shaft, and the clamp rotates with the central shaft.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] This invention relates to a device for detecting the adaptability of a laser displacement sensor on a highly reflective tilted surface. A first support is provided to hold the laser displacement sensor. A clamp holds the object to be measured. A central shaft rotates between a first and a second disc, causing the clamp to rotate and changing the tilt angle of the object, thus achieving an adjustable angle mode.

This device can detect the response capability of the laser displacement sensor under different angles, different reflectivities, and different distances between the objects.

[0018] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The first embodiment of this utility model provides a device for detecting the adaptability of a laser displacement sensor to a highly reflective tilted surface, such as... Figure 1 As shown, the system includes: a base 1, with a first support 2 and a second support 3 sequentially arranged along a first direction; both the first support 2 and the second support 3 are perpendicular to the first base 1; the first support 2 is movably connected to the base 1 and can move along the base 1 in the first direction; the second support 3 has a first disc 4 and a second disc 5 symmetrically fixed at both ends, with a central shaft 6 rotatably connected between the first disc 4 and the second disc 5, and one end of the central shaft 6 passes through the first disc 4 and is perpendicularly connected to a blade 7; a clamp 8 for holding the object to be measured is provided on the central shaft 6, and the clamp 8 rotates with the central shaft 6. The first direction is the length direction of the base 1.

[0021] In this embodiment, a first support 2 is provided for placing the laser displacement sensor. The object to be measured is held by a clamp 8. The central shaft 6 rotates between the first disk 4 and the second disk 5, driving the clamp 8 to rotate and changing the tilt angle of the object to be measured, thus achieving an adjustable angle mode. This allows for the detection of the response capability of the laser displacement sensor at different tilt angles of the object to be measured. The first support 2 can move along the base 1 in a first direction, thereby adjusting the distance between the object to be measured and the laser displacement sensor, and allowing for the detection of the response capability of the laser displacement sensor at different distances from the object to be measured. The clamp 8 can accommodate objects with different reflectivities, enabling a replaceable object mode, and allowing for the detection of the response capability of the laser displacement sensor on objects with different reflectivities. Based on this, the device for detecting the adaptability of the laser displacement sensor on highly reflective tilted surfaces in this embodiment can detect the response capability of the laser displacement sensor under different angles, different reflectivities, and different distances between the objects.

[0022] Specifically, such as Figure 2-3 As shown, the fixture 8 includes a first clamping plate 81 and a second clamping plate 82 arranged symmetrically. The distance between the first clamping plate 81 and the second clamping plate 82 is the same as the thickness of the object to be measured, and the two are connected by fasteners. A connecting plate 83 is vertically connected to the surface of the first clamping plate 81. A slot 84 adapted to the connecting plate 83 is opened on one side of the second clamping plate 82, and the connecting plate 83 is located in the slot 84. A groove 85 is connected to the bottom of the connecting plate 83. The open end of the groove 85 is connected to the connecting plate 83 to form a channel, and the central shaft 6 passes through the channel.

[0023] In this embodiment, the object to be tested is clamped by the first clamping plate 81 and the second clamping plate 82. The channel formed by the connecting plate 83 and the groove 85 is used to connect the central shaft 6, so that when the central shaft 6 rotates, it drives the object to be tested to rotate, thereby adjusting the angle of the object to be tested. Further, as... Figure 4 As shown, the first disc 4 has a second scale line 14 along its circumference. This allows for accurate determination of the adjustment angle of the object to be measured. The side wall of the first disc 4 has a groove corresponding to the second scale line 14, and the free end of the blade 7 is vertically connected to a positioning pin 15 that matches the groove. When rotated to a preset angle, the positioning pin 15 is engaged in the groove, thereby controlling the tilt angle of the object being measured and preventing inaccurate detection results due to the rotation of the blade 7.

[0024] To prevent the object under test from contacting the second support 3 and becoming unable to rotate when the central shaft 6 rotates, this embodiment provides an arc-shaped groove 9 on the second support 3 along a second direction, wherein the second direction is perpendicular to the first direction. The size of the arc-shaped groove 9 is adapted to the size of the object under test, ensuring that the end of the object under test does not contact the second support 3. Furthermore, the height of the first support 2 and the second support 3 is not limited, as long as the laser beam can illuminate the surface of the object under test 1.

[0025] Furthermore, a cylindrical shaft 10 is sleeved on the central shaft 6, and the central shaft 6 is rotatably connected to the first disk 4 through the cylindrical shaft 10. The first disk 4 has a through hole that matches the cylindrical shaft 10, and the cylindrical shaft 10 is located in the through hole, allowing it to rotate within the through hole. The central shaft 6 passes through the cylindrical shaft 10, ensuring the smooth rotation of the central shaft 6.

[0026] For example, the first bracket 2 is provided with a third scale line 13 along the second direction for accurately measuring the distance between multiple sensors; the surface of the first bracket 2 is provided with a positioning groove 16 adapted to the laser displacement sensor, and the size of the positioning groove 16 is adapted to the housing of the laser displacement sensor.

[0027] Furthermore, a boss 11 is fixed on the base 1, and the first support 2 includes a first platform 21. Two support blocks 22 are symmetrically connected to the bottom of the first platform 21. The distance between the two support blocks 22 is equal to the width of the boss 11. The two support blocks 22 engage with the boss 11, and the support blocks 22 can move along the boss 11. A positioning groove 16 is located on the first platform 21. A first scale line 12 is provided on the base 1 along a first direction. Specifically, a 9.5° inclined plane is formed on both sides of the base 1, and a length measurement scale (first scale line 12) is marked on the inclined plane for accurately measuring the distance between the laser displacement sensor and the object being measured. The distance between the object being measured and the laser displacement sensor can be adjusted through the first scale line 12.

[0028] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
