[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the 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. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.
[0035] Firstly, such as Figure 1 As shown, an embodiment of this application provides a laser spot centering detection device, including a first bracket 1, a second bracket 2, and a light-blocking plate 3. The first bracket 1 is used to fix a laser emitter 5, and the second bracket 2 is used to fix a spot display component 6, with the second bracket 2 and the first bracket 1 arranged opposite to each other along a first direction X. The light-blocking plate 3 is disposed on the side of the second bracket 2 opposite to the first bracket 1.
[0036] The laser spot centering detection device provided in this application embodiment fixes the laser emitter 5 to the first bracket 1 and the spot display 6 to the second bracket 2, with the first bracket 1 and the second bracket 2 arranged opposite each other along the first direction X. This reduces personnel operation in the laser emission direction. Furthermore, the light-blocking plate 3 located on the side of the second bracket 2 opposite to the first bracket 1 can block the laser emitted by the laser emitter 5, reducing the risk of laser irradiation on other objects. In other words, the laser spot centering detection device provided in this application embodiment reduces operator involvement, lowers risks, reduces errors caused by human operation, improves accuracy, simplifies the operation process, and increases efficiency.
[0037] The size of the light-blocking plate 3 can be set as needed. The light-blocking plate 3 can block the laser and prevent the laser from shining on other objects, thereby improving the safety of the detection process.
[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, the first bracket 1 is adapted to slide along the first direction X, and / or the second bracket 2 is adapted to slide along the first direction X.
[0039] By sliding the first support 1 and / or the second support 2 along the first direction X, the distance between the first support 1 and the second support 2 can be adjusted, thereby adjusting the distance between the laser emitter 5 and the spot display 6. In practical applications, the distance between the laser emitter 5 and the spot display 6 can be adjusted according to parameters such as the light intensity of the laser emitted from the laser emitter 5, thereby improving the accuracy of centering detection and expanding the applicability of the laser spot centering detection device.
[0040] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the laser spot centering detection device also includes a base 4, on which a slide rail 41 is provided, extending along a first direction X. A first slider 42 and a second slider 43 are provided on the slide rail 41. A first support 1 is slidably connected to the slide rail 41 via the first slider 42, and a second support 2 is slidably connected to the slide rail 41 via the second slider 43.
[0041] In other words, the cooperation of the first slider 42, the second slider 43, and the slide rail 41 ensures the accuracy and stability of the sliding, and the distance between the first support 1 and the second support 2 can be adjusted as needed. The slide rail 41, which extends along the first direction X, enables the first support 1 and the second support 2 to maintain a relative position along the first direction X during the sliding process, reducing the problem of the emitted laser from the laser emitter 5 deviating from the spot display 6, improving the accuracy of centering detection, and reducing the danger caused by laser deviation.
[0042] It is understandable that other matching forms can also be selected to achieve sliding of the first bracket 1 and the second bracket 2 along the first direction X. For example, a sliding groove is provided on the base 4, and the first slider 42 and the second slider 43 are slidably connected through the sliding groove.
[0043] In some embodiments, such as Figure 3 and Figure 4 As shown, the first bracket 1 has a fixing hole 11 that extends through the first direction X, and the laser emitting element 5 is adapted to be inserted into the fixing hole 11.
[0044] The laser emitter 5 can be fixed to the first bracket 1 by means of the fixing hole 11 through the first direction X, and the laser emitter 5 can emit laser light along the first direction X, so that the laser light shines on the spot display 6 along the first direction X, and the centerness can be judged by the laser spot on the spot display 6.
[0045] For example, the laser emitter 5 can be an optical isolator, allowing only unidirectional laser transmission and collimating the beam transmitted in the optical fiber. The first bracket 1 can fix the optical isolator, and the laser emitted through the optical isolator irradiates towards the second bracket 2 to form a laser spot on the spot display device 6. The centering accuracy is determined by the laser spot. The spot display device 6 can be a frequency doubler. The laser emitted from the laser emitter 5 can form a laser spot on the frequency doubler. The preset position and range on the frequency doubler can be defined according to parameters such as the size of the laser emitter 5 and the preset emission angle of the laser spot. When the laser emitted from the laser emitter 5 irradiates the frequency doubler to form a laser spot, the actual position and range of the laser spot can be compared with the preset position and range on the frequency doubler to determine whether the centering accuracy of the laser spot meets the requirements.
[0046] It is understandable that the laser emitter 5 can also be other laser collimation devices, and the spot display device 6 can also be other photosensitive films that can observe laser spots.
[0047] In some embodiments, such as Figure 4As shown, a first limiting member 12 is also provided on the first bracket 1. The first limiting member 12 is provided on the side of the first bracket 1 away from the second bracket 2, and the first limiting member 12 is used to limit the position of the laser emitting member 5 in the fixing hole 11.
[0048] The first limiting member 12 can limit the length of the laser emitter 5 extending into the fixing hole 11, and the first limiting member 12 can also support the laser emitter 5.
[0049] For example, such as Figure 4 As shown, the first limiting member 12 can be disposed below the fixing hole 11. When the laser emitter 5 passes through the fixing hole 11, the first limiting member 12 can support the laser emitter 5. At the same time, the thickness of the first limiting member 12 along the first direction X limits the length of the first limiting member 12 extending out of the fixing hole 11, thus ensuring the stability of the laser emitter 5.
[0050] In some embodiments, such as Figure 4 As shown, the first bracket 1 is also provided with a clamping member 13, which is used to clamp and fix the laser emitting member 5 in the fixing hole 11.
[0051] The clamping member 13 can press and fix the laser emitter 5 into the fixing hole 11, reducing the shaking of the laser emitter 5, ensuring stability during the laser spot centering detection process, and improving accuracy. In addition, the clamping member 13 and the fixing hole 11 can be used to accommodate laser emitters 5 of different sizes and structures, thereby expanding the applicability of the laser spot centering detection device.
[0052] For example, such as Figure 4 As shown, the clamping member 13 can move in the up and down direction. When the clamping member 13 moves up, it is convenient to install the laser emitter 5 into the fixing hole 11 or remove it from the fixing hole 11. When the laser emitter 5 is installed into the fixing hole 11, the clamping member 13 can move down to fix the laser emitter 5 in the fixing hole 11, reducing the shaking of the laser emitter 5 during the detection process.
[0053] In some embodiments, such as Figure 4 As shown, the first bracket 1 also includes a clamping knob 14, which is drivenly connected to the clamping member 13. The clamping knob 14 can adjust the preload of the clamping member 13, thereby facilitating the installation and removal of the laser emitter 5. The adjustment of the preload of the clamping member 13 can also ensure the stability of the laser emitter 5 and reduce the shaking of the laser emitter 5 during the detection process.
[0054] In some embodiments, please refer to Figure 2 A first positioning element 44 is provided on the base 4. The first bracket 1 and / or the second bracket 2 are adapted to be fixed to the base 4 by means of the first positioning element 44.
[0055] The first positioning element 44 can fix the first bracket 1 and / or the second bracket 2, thereby reducing the interference to the first bracket 1 and / or the second bracket 2 during the detection process and ensuring the accuracy of the detection.
[0056] In some embodiments, please refer to Figures 1-3 , Figure 5 The laser spot centering detection device also includes a second positioning element 15 and a third positioning element 21. The second positioning element 15 is connected to the first support 1, and the first support 1 is connected to the first positioning element 44 through the second positioning element 15, so that the first support 1 is fixed on the base 4. The third positioning element 21 is connected to the second support 2, and the second support 2 is connected to the first positioning element 44 through the third positioning element 21, so that the second support 2 is fixed on the base 4.
[0057] That is, the first bracket 1 and the base 4 are fixedly connected by the cooperation of the second positioning member 15 and the first positioning member 44, and the second bracket 2 and the base 4 are fixedly connected by the cooperation of the third positioning member 21 and the first positioning member 44.
[0058] Specifically, the first positioning element 44 can be a first positioning hole, and the second positioning element 15 can be a second positioning hole. The first positioning element 44 and the second positioning element 15 can be fixed by fasteners such as pins or fixing bolts, thereby fixing the first bracket 1 to the base 4. Similarly, the third positioning element 21 can be a third positioning hole. The first positioning element 44 and the third positioning element 21 can be fixed by fasteners such as pins or fixing bolts, thereby fixing the second bracket 2 to the base 4.
[0059] In some embodiments, such as Figure 1 As shown, a second limiting member 45 is also provided on the base 4. The second limiting member 45 is located at the end of the slide rail 41 away from the light-blocking plate 3, and the second limiting member 45 is used to limit the sliding range of the first bracket 1 and the second bracket 2.
[0060] The second limiting member 45 can limit the sliding range of the first bracket 1 and the second bracket 2, prevent the first bracket 1 and the second bracket 2 from falling off the slide rail 41, and ensure structural stability.
[0061] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
