[0032] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] like Figures 1 to 5 As shown, an embodiment of the present invention provides a lifting assembly 100, comprising a lifting base 1 and a driving member 5. The top of the lifting base 1 has a mounting surface 2, the mounting surface 2 is used to mount a light beam processing device 200, and the driving member 5 is used to drive the lifting base 1 to move up and down;

[0034] A clearance space 3 is provided in the center of the lift base 1 to avoid external equipment or structures. In this embodiment, the lift assembly 100 is in its initial position, and the top mounting surface 2 of the lift base 1 is used to mount the beam processing device 200. At this point, the clearance space 3 is idle and does not interfere with external equipment or structures. To adjust the height of the beam processing device 200, the lift base 1 is driven up and down by a driver (such as a motor, cylinder, or manual operating mechanism). During this movement, the clearance space 3 within the lift base 1 ensures that it does not collide with or interfere with external equipment or structures. After reaching the target height, the lift base 1 stops. At this point, the beam processing device 200 is at the desired operating height, allowing for subsequent beam processing operations. During the lifting process, if external equipment or structures need to enter the lifting base 1's path, the clearance space 3 ensures that the lift base 1 can smoothly avoid these obstacles without interrupting or causing any malfunctions in the lifting operation. Lifting assembly 100 can move vertically, allowing light beam processing device 200 to adapt to different working height requirements. The presence of avoidance space 3 ensures that lifting assembly 100 does not occupy additional space during vertical movement, thereby optimizing space utilization. This is particularly important in space-constrained environments, such as laboratories and production lines. Furthermore, this lifting assembly 100 is not only suitable for light beam processing device 200 but can also be widely used in other scenarios requiring height adjustment and avoidance space 3, such as precision machining, automated production, and other fields.

[0035] See Figure 3 In one embodiment, the lifting base 1 includes a top plate 11, a side plate 12, and a bottom plate 13. One end of the top plate 11 is connected to the top end of the side plate 12, and one end of the bottom plate 13 is connected to the bottom end of the side plate 12. In the horizontal direction, the top plate 11 and the bottom plate 13 are located on the same side of the side plate 12.

[0036] The top surface of the top plate 11 serves as the mounting surface 2. The top plate 11, side plates 12, and bottom plate 13 enclose a clearance space 3. In this embodiment, the lift base 1 is composed of the top plate 11, side plates 12, and bottom plate 13, forming an open frame structure. This compact, space-saving structure allows for flexible height adjustment to accommodate spot detection equipment at varying heights, enhancing the system's adaptability and flexibility. The design of the clearance space 3 prevents interference between the lift base 1 and surrounding equipment during movement, reducing complexity and potential damage during installation and operation.

[0037] See Figure 2 and Figure 3 , in one embodiment, the lifting assembly 100 further includes a fixing seat 4;

[0038] The driving member 5 includes a guide rod 51, a connecting seat 52, and an adjusting member. The guide rod 51 extends vertically, with the bottom end of the guide rod 52 fixed to the fixing seat 4. The connecting seat 52 is fixed to the top plate 11, which is slidably connected to the guide rod 51. The adjusting member is connected to the connecting seat 52, and the adjusting member drives the lifting base 1 up and down through the connecting seat 52. In this embodiment, the adjusting member can be manually operated or electrically driven. The adjusting member precisely controls the vertical movement of the lifting base 1 through the connecting seat 52, ensuring that the light beam processing device 200 can be accurately positioned at the desired height.

[0039] See Figure 3 In one embodiment, the adjustment member is an adjustment stud 53. The connecting base 52 is provided with a threaded hole extending in the vertical direction. The adjustment stud 53 is threadedly connected to the threaded hole, and the bottom end of the adjustment stud 53 abuts the top of the guide rod 51. In this embodiment, the guide rod 51 is fixed to the fixed base 4 and extends in the vertical direction, serving as a guide and support structure for the lifting movement. The connecting base 52 is connected to the adjustment stud 53 through the threaded hole, ensuring a secure connection between the lifting base 1 and the adjustment stud 53. The adjustment stud 53 is threadedly connected to the threaded hole of the connecting base 52 and extends to the guide rod 51. By manually or electrically rotating the adjustment stud 53, the position of the lifting base 1 can be precisely adjusted. By using the design of the guide rod 51 and the adjustment stud 53, the lifting assembly 100 provides an effective lifting function while maintaining a simple and compact structure. The adjustment stud 53 has a fine thread, which can achieve precise control of the height of the beam processing device 200.

[0040] See Figure 3 In one embodiment, the adjustment stud 53 includes a rotating head 531, a threaded section 532, and a smooth section 533, which are connected in sequence. The threaded section 532 is threadedly connected to the threaded hole, the rotating head 531 is located outside the threaded hole, and the bottom of the smooth section 533 abuts the top of the guide rod 51. In this embodiment, the rotating head 531 is located outside the threaded hole, allowing the adjustment stud 53 to be rotated manually or with a tool to achieve precise positioning of the lifting base 1, which is simple and quick to operate. Furthermore, a positioning groove is provided at the top of the guide rod 51, and a positioning protrusion is provided at the bottom of the smooth section 533. The positioning protrusion is inserted into the positioning groove, thereby ensuring a stable connection between the adjustment stud 53 and the guide rod 51.

[0041] See Figure 3 In one embodiment, the driving member 5 further includes an elastic member 54 , an accommodating space 41 is defined within the fixing seat 4 , and the bottom plate 13 is located in the accommodating space 41 ;

[0042] The top end of the elastic member 54 is connected to the fixing base 4, and the bottom end of the elastic member 54 is connected to the base plate 13. The elastic member 54 is capable of elastic deformation in the vertical direction. In this embodiment, when the adjustment screw 53 rotates, the top plate 11 moves up and down along the guide rod 51. The elastic member 54 ensures smooth movement and effective shock absorption, thereby providing a cushioning and restoring force. The elastic member 54 is a spring. The addition of the elastic member 54 provides additional cushioning and restoring functions, reducing shock and vibration, protecting the component, and improving positioning accuracy and reliability.

[0043] See Figure 3 In one embodiment, the fixing base 4 includes a top plate 43, a side plate 44, and a bottom plate 45. One end of the top plate 43 is connected to the top end of the side plate 44, and one end of the bottom plate 45 is connected to the bottom end of the side plate 44. In the horizontal direction, the top plate 43 and the bottom plate 45 are located on the same side of the side plate, and the bottom plate 13 is located between the top plate 43 and the bottom plate 45 in the vertical direction.

[0044] The top end of the elastic member 54 is connected to the top plate 43. In this embodiment, the fixing base 4 is composed of the top plate 43, the side plates 44, and the bottom plate 45, forming a sturdy support structure that stably fixes the lifting assembly 100. The top plate 43 and the bottom plate 45 are located on the same side of the side plate 44. This layout makes the fixing base 4 more compact, reduces the horizontal space occupied, and facilitates installation and layout in limited spaces. The addition of the elastic member 54 provides additional cushioning and reset capabilities, improving the safety of the lifting assembly 100.

[0045] See Figure 3 In one embodiment, the lifting assembly 100 further includes a blocking member 7 , a threaded mounting hole 42 is provided on the top plate 43 , the blocking member 7 is threadedly connected to the upper end of the threaded mounting hole 42 , and the top end of the elastic member 54 is inserted into the lower end of the threaded mounting hole 42 and abuts against the bottom end surface of the blocking member 7 ;

[0046] The top of the base plate 13 is provided with an elastic member mounting hole, into which the bottom end of the elastic member 54 is inserted. In this embodiment, the elastic force of the elastic member 54 can be adjusted by twisting the blocking member 7, thereby precisely controlling the reset force and cushioning performance of the lifting base 1. This design allows the elastic force of the elastic member 54 to be adjusted according to actual application requirements to accommodate different loads and usage environments. The coordinated operation of the blocking member 7 and the elastic member 54 achieves precise, smooth, and efficient lifting. The provision of threaded mounting holes and elastic member mounting holes facilitates the positioning and installation of the elastic member 54.

[0047] See Figure 3In one embodiment, the lifting assembly 100 further includes a guide shaft 6 extending in the vertical direction and fixed in the accommodating space 41. The base plate 13 is slidably connected to the guide shaft 6. In this embodiment, the lifting assembly 100 further includes a sliding bearing installed in the fixed base 4 and cooperating with the guide shaft 6. This sliding bearing enables the guide shaft 6 to slide with low friction. The guide shaft 6 provides precise guidance, making the movement of the lifting base 1 more stable and precise. By integrating the guide shaft 6 and the elastic member 54 within the fixed base 4, this design achieves a compact mechanical structure, saving space while maintaining efficient functionality.

[0048] According to the lifting assembly 100 provided in the embodiment of the present invention, the avoidance space 3 in the middle of the lifting seat 1 is designed to take into account the compatibility with external equipment or structures, can adapt to different equipment layouts, and improve the versatility and applicability of the lifting assembly 100. The lifting assembly 100 can easily avoid the surrounding equipment or structures when moving vertically, thereby improving the layout flexibility and adaptability of the equipment. This design allows light spot detection to be performed without disassembling or moving surrounding equipment, simplifying the operation process. Compared with the traditional light spot detection lifting mechanism, the lifting assembly 100 of the present application reduces the space required during the lifting process by setting the avoidance space 3 in the middle of the lifting seat 1. On its lifting path, it can free up a part of the space for use by some external equipment, thereby improving space utilization. This is particularly important for application scenarios with limited space, especially in precision instruments or compact equipment, which can effectively save valuable space resources.

[0049] In addition, if Figure 4 and Figure 5 As shown, an embodiment of the present invention provides a mechanism for spot detection, comprising a light beam processing device 200 and the lifting assembly 100 of the above embodiment, wherein the light beam processing device 200 is disposed on the mounting surface 2;

[0050] The light beam processing device 200 is used to steer the light beam to be detected.

[0051] See Figure 5 In one embodiment, the light beam processing device 200 includes a wedge-shaped mirror 1001 and a mounting base 1002. The mounting base 1002 is disposed on the mounting surface 2, and the wedge-shaped mirror 1001 is mounted on the mounting base 1002. The wedge-shaped mirror 1001 is capable of reflecting at least a portion of the light beam to be detected that strikes the wedge-shaped mirror 1001. In this embodiment, the wedge-shaped mirror 1001 is capable of reflecting at least a portion of the light beam to be detected that strikes the wedge-shaped mirror 1001, thereby precisely controlling the direction of the light beam and achieving beam deflection. This facilitates spatial layout and, for example, is applicable to applications with limited space (e.g., a limited optical path).

[0052] In one embodiment, the light beam processing device 200 further includes an attenuation plate assembly connected to the mounting base 1002 and arranged opposite the reflective surface of the wedge-shaped mirror 1001. The attenuation plate assembly is capable of reducing the intensity of the light beam to be detected incident upon the wedge-shaped mirror 1001. In this embodiment, the attenuation plate assembly and the reflective surface of the wedge-shaped mirror 1001 are arranged in a vertical direction relative to each other. The attenuation plate assembly reduces the intensity of the light beam to be detected incident upon the wedge-shaped mirror 1001, providing precise light intensity regulation, protecting sensitive detection equipment from damage caused by excessive light intensity, and ensuring measurement accuracy.

[0053] See Figure 5 In one embodiment, the attenuation sheet assembly includes an attenuation sheet body 1003, an attenuation sheet fixing seat 1005, and an attenuation sheet connecting seat 1006. The attenuation sheet fixing seat 1005 and the attenuation sheet connecting seat 1006 are connected to form a first receiving space therein. The attenuation sheet fixing seat 1005 is provided with a first through hole 1007 penetrating the attenuation sheet fixing seat 1005, and the attenuation sheet connecting seat 1006 is provided with a second through hole 1008 penetrating the attenuation sheet connecting seat 1006.

[0054] The attenuation sheet body 1003 is disposed within the first storage space, with the first through-hole 1007 positioned opposite the reflective surface of the wedge-shaped mirror 1001. The attenuation sheet body 1003 can reduce the intensity of the light beam to be detected transmitted through the first through-hole 1007. The attenuation sheet body 1003 can also transmit the attenuated light beam to the exterior of the first storage space through the second through-hole 1008. In this embodiment, the attenuation sheet body 1003 and the wedge-shaped mirror 1001 are positioned vertically opposite each other. The provision of the attenuation sheet fixing base 1005 and the attenuation sheet connecting base 1006 facilitates the installation of the attenuation sheet body 1003. By reducing the light beam intensity through the attenuation sheet assembly, damage to the detection equipment caused by excessively strong light beams can be reduced, thereby extending the service life of the equipment.

[0055] In one embodiment, the wedge-shaped mirror 1001 is capable of reflecting a portion of the light beam to be detected that strikes the wedge-shaped mirror 1001; further, the wedge-shaped mirror 1001 is capable of refracting another portion of the light beam to be detected that strikes the wedge-shaped mirror 1001. In this embodiment, the wedge-shaped mirror 1001 is capable of both reflection and refracting the same light beam, enabling a single optical element to perform two beam processing functions. Through reflection, the wedge-shaped mirror 1001 deflects a portion of the light beam to be detected, directing it in a predetermined direction. Furthermore, by refracting a portion of the light beam, the intensity of the reflected beam is reduced, preventing damage to sensitive components caused by excessive light intensity.

[0056] See Figure 5In one embodiment, the thickness of wedge-shaped mirror 1001 gradually increases from top to bottom. In this embodiment, the varying thickness of wedge-shaped mirror 1001 causes light in the detection beam to produce different refractive indices as it passes through wedge-shaped mirror 1001, facilitating precise control of the beam's direction and intensity.

[0057] See Figure 5 In one embodiment, the mounting base 1002 is tilted on a side facing away from the lifting base 1, and the wedge mirror 1001 is connected to the side of the mounting base 1002 facing away from the lifting base 1, so that the wedge mirror 1001 can reflect at least a portion of the light beam to be detected that is directed toward the wedge mirror 1001 in the vertical direction. In this embodiment, the mounting base 1002 has a wedge-shaped structure, and a mounting groove is provided on the top side of the mounting base 1002, into which the wedge mirror 1001 is mounted. Furthermore, a limit portion extends from the bottom of the mounting base 1002 to define the position of the wedge mirror 1001. The tilted mounting of the wedge mirror 1001 allows the light beam to be reflected in the vertical direction, precisely changing the propagation direction of the light beam and facilitating the layout of the overall structure in space-constrained environments.

[0058] See Figure 5 In one embodiment, the light beam processing device 200 further includes a protective cover 1004. The protective cover 1004 covers the mounting base 1002, and the interiors of the protective cover and the mounting base 1002 form a second storage space. The wedge mirror 1001 is disposed in the second storage space. A light beam entrance is provided in the protective cover 1004. The light beam entrance is arranged opposite the reflective surface of the wedge mirror 1001 and communicates with the second storage space. In this embodiment, the protective cover 1004 and the wedge mirror 1001 are arranged horizontally opposite each other. The provision of the protective cover 1004 ensures the safety of the light beam before entering the wedge mirror 1001, preventing external factors such as dust and debris from affecting the beam quality, while also protecting the wedge mirror 1001 from damage.

[0059] According to the mechanism for spot detection provided by the embodiment of the present invention, the avoidance space 3 in the middle of the lifting base 1 is designed to take into account compatibility with external equipment and can adapt to different equipment layouts, allowing the lifting assembly 100 to easily avoid surrounding equipment during vertical movement. Compared with traditional spot detection lifting mechanisms, the mechanism provided with the avoidance space 3 occupies less space during the lifting process, making it particularly suitable for space-constrained optical path systems. The design of the lifting assembly 100 allows the light beam processing device 200 to flexibly adjust its height to adapt to different detection requirements. The light beam processing device 200 can not only achieve light beam steering but also reduce the intensity of the light beam, thereby improving the accuracy and reliability of spot detection.

[0060] In addition, if Figure 1As shown, an embodiment of the present invention provides a light spot detection device, including a light spot analyzer 300 and a mechanism for light spot detection of the above embodiment, wherein the light spot analyzer 300 is used to detect the light beam to be detected after being processed by the light beam processing device 200. In this embodiment, during operation, the light beam processing device 200 first deflects and weakens the incident light beam to be detected to adapt to the detection requirements of the light spot analyzer 300. This step ensures that the light beam has an appropriate direction and intensity before entering the light spot analyzer 300, preventing an overly strong light beam from damaging the detection equipment or affecting the detection accuracy. The processed light beam is transmitted to the light spot analyzer 300, which receives the processed light beam and analyzes its light spot quality. The analyzed parameters may include indicators such as the uniformity of the light spot, the diameter of the light spot, and the divergence angle. By pre-processing the light beam, the device effectively protects sensitive detection equipment, such as the Spot Analyzer 300, from damage caused by an overly strong beam. Through precise beam processing and high-quality spot analysis, the device provides highly accurate spot quality detection results, thereby improving the accuracy of the entire detection process.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
