[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Figure 1 A schematic diagram of the optical measurement auxiliary fixture in this invention is shown. Figure 2 A schematic diagram of the lifting module in this utility model is shown. Figure 3 A cross-sectional view of the lifting module in this utility model is shown. Figure 4 This shows a first structural schematic diagram of the rotating module in this utility model. Figure 5 This diagram shows a second structural schematic of the rotating module in this invention. Figure 6 A schematic diagram of the rotating plate in this utility model is shown. Figure 7The diagram shows the structure of the measurement module in this invention. The optical measurement auxiliary fixture includes a base 1 and a measurement fixture 2 with an edge of the base 1. The measurement fixture 2 includes a lifting module 21 and a rotating module 22. The lifting module 21 includes a base 211 and a T-shaped lead screw 212. The base 211 has a moving cavity 2110. The T-shaped lead screw 212 is rotatably inserted into the moving cavity 2110. The rotating module 22 is disposed on the T-shaped lead screw 212 and moves vertically under the drive of the T-shaped lead screw 212. The rotating module 22 includes a mounting base 221 and a rotating plate 222. The mounting base 221 has a fixing block 223 with a first connecting hole 2231 at one end near the T-shaped lead screw 212. The fixing block 223 is sleeved on the T-shaped lead screw 212 based on the first connecting hole 2231. The rotating plate 222 is rotatably mounted on the mounting base 221 and has a measuring module 24 mounted on it. The side wall of the base 211 has graduations, and the end face of the mounting base 221 connected to the rotating plate 222 also has graduations. In this embodiment, the lifting module 21 is used to adjust the height of the rotating module 22, thereby adjusting the height of the measuring module 24 to meet various height testing requirements. The rotating module 22 is used to adjust the angle of the measuring module 24 to meet various angle testing requirements. The testing module is used to fix various optical instruments so that they can function normally. The fixing block 223 is connected to the T-shaped lead screw 212 based on the first connecting hole 2231. When the T-shaped lead screw 212 rotates, the fixing block 223 moves along the thread on the T-shaped lead screw 212, driving the mounting base 221 to move, thereby adjusting the position of the rotating module 22. The side wall of the mounting base 221 is also provided with a reference line. The reference line and the scale on the side wall of the base 211 are located on the same reference plane, which facilitates the alignment of the reference line on the base 211 with the scale on the base 211. The scale on the base 211 corresponds to the horizontal height, and the scale on the mounting base 221 corresponds to the rotation angle. When adjusting the position of the mounting base 221 relative to the base 211, the scale on the side wall of the base 211 can be observed, and the mounting base 221 can be moved to the desired scale position to achieve precise position adjustment. Similarly, when adjusting the position of the mounting base 221 relative to the base 211, the scale on the end face of the mounting base 221 can be observed, and the rotating plate 222 can be rotated to the desired scale position to achieve precise control. During optical testing, the test distance and angle only need to be adjusted at the beginning of the test, avoiding the need to adjust the test distance and angle for each sample, greatly saving test time and improving optical testing efficiency.
[0030] It should be noted that the lifting module 21 adopts a T-shaped lead screw 212. The T-shaped lead screw 212 can maintain smooth and efficient sliding during operation, effectively reducing friction and wear, thereby improving the service life of the lifting module 21.
[0031] Furthermore, a second connecting hole 2111 is provided on the top of the base 211, and a fixed base plate 23 is provided on the bottom of the base 211. A third connecting hole 231 is provided on the fixed base plate 23. One end of the T-shaped lead screw 212 is inserted into the second connecting hole 2111, and the other end of the T-shaped lead screw 212 is inserted into the third connecting hole 231. The two ends of the T-shaped lead screw 212 are respectively inserted into the second connecting hole 2111 and the third connecting hole 231, forming a stable connection structure. This ensures a tight fit between the T-shaped lead screw 212 and the connecting hole, avoiding structural instability caused by loosening or displacement, and thus enhancing the structural stability of the lifting module 21.
[0032] It should be noted that a first bearing is provided in the second connecting hole 2111 and a second bearing is provided in the third connecting hole 231. The first bearing and the second bearing can reduce the friction and wear between the T-shaped lead screw 212 and the base 211 or between the T-shaped lead screw 212 and the connecting base plate. The bearings ensure the accuracy and stability of the T-shaped lead screw 212, thereby improving the performance and efficiency of the lifting module 21.
[0033] Furthermore, a rotating wheel 213 is provided on the end of the T-shaped lead screw 212 away from the base 1, and the T-shaped lead screw 212 is driven to rotate by the rotation. In this embodiment, the rotating wheel 213 is fixedly connected to the end of the T-shaped lead screw 212 away from the base 1. When the rotating wheel 213 is rotated under force, it drives the T-shaped lead screw 212 to rotate. When the T-shaped lead screw 212 rotates, the fixing block 223 moves along the thread of the T-shaped lead screw 212, realizing the vertical movement of the fixing block 223, thereby driving the entire rotating module 22 to move vertically. This facilitates the adjustment of the height of the measuring module 24 to meet the testing requirements of various heights.
[0034] Furthermore, the rotating plate 222 extends from one end near the mounting base 221 to form a rotating platform 224. The rotating platform 224 has a rotating groove 2241 and a rotating rod 2242, which is inserted into the mounting base 221. The mounting base 221 has a corresponding rotating hole that matches the rotating rod 2242. This rotating hole is located at the center of the mounting base 221, and the rotating rod 2242 is inserted into the rotating hole. This ensures that the rotating plate 222 rotates around the rotating hole as its center during rotation, avoiding the risk of deviation during rotation and improving the accuracy of the rotation angle of the rotating module 22. The rotating groove 2241 provides space for fixing parts, allowing the fixing parts to pass through the rotating groove 2241 to fix the entire rotating plate 222, which helps improve the stability of the optical measurement auxiliary fixture.
[0035] Furthermore, the mounting base 221 is provided with a plurality of fixing bolts 2211, each fixing bolt 2211 being located in the rotating groove 2241, and each fixing bolt 2211 being adapted to abut against the end face of the rotating platform 224. In this embodiment, the mounting base 221 is provided with two fixing bolts 2211, and the mounting base 221 has two corresponding fixing holes, with the two fixing bolts 2211 correspondingly disposed in the two fixing holes. The two fixing bolts 2211 are located in the rotating groove 2241. When the rotating plate 222 needs to be fixed, the two fixing bolts 2211 are screwed into the fixing holes until the fixing bolts 2211 abut against the end face of the rotating platform 224. The fixing bolts 2211 exert a force on the rotating platform 224, making the rotating platform 224 fit tightly against the mounting base 221, increasing the friction between the rotating platform 224 and the mounting base 221, which helps to fix the rotating platform 224 at a specified angle. When the rotating plate 222 needs to rotate, the fixing bolts 2211 do not contact the end face of the rotating platform 224, and the friction between the rotating plate 222 and the mounting base 221 is reduced, which helps the rotating platform 224 to rotate smoothly to the required angle.
[0036] Furthermore, the rotating plate 222 is provided with multiple mounting holes 2221, and the measuring module 24 is detachably connected to the rotating plate 222 based on the multiple mounting holes 2221. In this embodiment, the rotating plate 222 is provided with sixteen mounting holes 2221, which are divided into two columns and eight rows. The two columns of mounting holes 2221 are symmetrically distributed, and the distance between adjacent rows of mounting holes 2221 is equal. The measuring module 24 can select the installation position according to the usage scenario. When the measuring module 24 needs to perform multiple different measurements, after measuring the first measurement, the measuring module 24 can be detached from the rotating plate 222 and its position on the rotating plate 222 can be adjusted according to the next measurement to adapt to different detection conditions and improve the flexibility of the optical measurement auxiliary fixture.
[0037] Furthermore, the measurement module 24 includes a measurement fixture 241 and a plurality of connecting posts 242. One end of each connecting post 242 is connected to the mounting hole 2221, and the other end of each connecting post 242 is connected to the measurement fixture 241. In this embodiment, the measurement module 24 includes four connecting posts 242. One of the four connecting posts 242 corresponds to one of the four apex corners of the measurement fixture 241. The four connecting posts 242 fix the position of the measurement fixture 241 on the rotating plate 222 from four positions, forming a stable quadrilateral structure, which gives the measurement fixture 241 high stability and helps to enhance the stability of the measurement fixture 241 fixed on the rotating plate 222.
[0038] It should be noted that in the optical inspection process, accurate positioning of the test distance and angle is the key to ensuring the consistency of the test data. The scale of this fixture can guarantee the consistency of the test data.
[0039] Furthermore, the base 1 is provided with multiple fixing grooves 11, which are distributed on the base 1 at preset positions. The base 1 is provided with more than four fixing grooves 11, which are used to fix various testing tools, preventing the testing tools from loosening or shifting during operation, and helping to maintain the overall stability and operating accuracy of the equipment.
[0040] It should be noted that the base 1 is detachably connected to the lifting module 21, and different bases 1 can be replaced according to different usage conditions. Different bases 1 can be provided with different numbers and shapes of fixing grooves 11 to adapt to different detection conditions and improve the flexibility of the optical measurement auxiliary fixture.
[0041] Furthermore, the base of the lifting module 21 is provided with multiple fixing feet 3. One fixing surface of any fixing foot 3 is connected to the base 1, and the other fixing surface of the foot is connected to the lifting module 21. In this embodiment, the base of the lifting module 21 is provided with two fixing feet 3, each of which is an L-shaped fixing foot 3 composed of two connecting plates, which are perpendicular to each other. Each connecting plate has one fixing surface, meaning the L-shaped fixing foot 3 has two fixing surfaces. One fixing surface of the L-shaped fixing foot 3 is fixed to the lifting module 21 with screws, and the other fixing surface of the L-shaped fixing foot 3 is fixed to the base 1 with screws, so that the lifting module 21 is stably fixed on the base 1, which helps to improve the structural stability of the optical measurement auxiliary fixture.
[0042] Furthermore, the optical measuring fixture 2 is made of aluminum alloy. Aluminum alloy has high mechanical strength, which helps the optical measuring auxiliary fixture resist external forces without damage, thus extending its service life. However, the measuring tool 241 in the optical measuring fixture 2 can also be made of polypropylene (PP). Polypropylene has excellent electrical insulation properties, which can effectively isolate current leakage from the lamp when testing it, ensuring that the current is transmitted along a predetermined path, thereby improving the safety and reliability of the optical measuring auxiliary fixture.
[0043] In summary, this invention, by incorporating a lifting module to adjust the height of the rotating module, and consequently the height of the measuring module, satisfies testing requirements at various heights. Furthermore, the invention includes a rotating module to adjust the angle of the measuring module, accommodating testing at various angles. Both the rotating and lifting modules are equipped with scales, allowing for adjustment of the testing distance and angle only at the start of the test, avoiding the need to adjust the testing distance and angle for each sample, thus significantly saving testing time and improving optical testing efficiency.
[0044] Furthermore, the above description provides a detailed introduction to an optical measurement auxiliary fixture provided by the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. 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 utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
