[0031] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 5 As shown, a spectral testing lens fixture comprises:

[0033] A substrate 1, a test lens 2 is placed on the substrate 1, a light hole 10 is provided on the substrate 1, and before testing, the position of the test lens 2 is adjusted so that the center of the test lens 2 is aligned with the center of the light hole 10 as much as possible, and a slide groove 3 is provided on the substrate 1, and the slide groove 3 corresponds to the clamping portion;

[0034] A positioning part, the positioning part is used to position the test lens 2, the positioning part comprises a positioning block 4, and the positioning block 4 can slide relative to the substrate 1;

[0035] The clamping part is provided with two groups, and the two groups of clamping parts are arranged opposite to each other. The two groups of clamping parts are respectively in contact with the opposite sides of the test lens 2. The clamping part is used to clamp and fix the test lens 2. The clamping part includes a fixing member 7, an elastic member 6 and a clamping member 5. The fixing member 7 is fixedly installed on the substrate 1. The first end of the elastic member 6 is connected to the fixing member 7, and the second end of the elastic member 6 is connected to the clamping member 5. The clamping member 5 slides in the slide groove 3.

[0036] The test lens 2 is positioned by the positioning part, and the positioning block 4 is slid along the substrate 1 according to the size of the test lens 2. The position of the positioning block 4 can be adjusted according to the size of the test lens 2, so that the center of the test lens 2 is aligned with the center of the light hole 10 on the substrate 1 as much as possible. The positioning block 4 can support the test lens 2, so that the lens will not fall during the placement process, thereby ensuring the positioning effect of the test lens 2. The lens is clamped and fixed by the clamping member 5. Under the elastic force of the elastic member 6, the clamping member 5 can ensure close contact with the test lens 2, thereby ensuring the clamping and fixing effect of the test lens 2. When testing, it is ensured that the substrate 1 and the test light are perpendicular, and the test lens 2 and the substrate 1 only need to be close, so that lenses with a certain size range and thickness can be accurately measured.

[0037] It should be noted that the substrate 1 is a rectangular plate, the clamping portion and the positioning portion are both mounted on the substrate 1, the extension line of the positioning portion and the extension line of the clamping portion are perpendicular to each other, and during testing, the substrate 1 is placed vertically.

[0038] like Figure 1 and Figure 4 As shown, in some embodiments, the clamping member 5 includes an integrally formed slider 51 and a clamping block 52, the slider 51 is connected to the second end of the elastic member 6, and the end surface of the slider 51 close to the slide groove 3 extends on both sides to form a clamping plate 54, and the clamping plate 54 cooperates with the slide groove 3 so that the clamping plate 54 can slide along the slide groove 3. When the test lens 2 needs to be clamped and fixed, the slider 51 is moved in the slide groove 3 in the direction close to the elastic member 6, and the clamping plate 54 and the clamping block 52 move with the slider 51, and the slide groove 3 can limit and guide the clamping plate 54 to ensure that the slider 51 moves in a specific direction, the elastic member 6 is compressed, and after the test lens 2 is positioned by the positioning block 4, the slider 51 is released. Under the elastic force of the elastic member 6, the clamping block 52 is tightly attached to the test lens 2 to achieve the clamping and fixing operation of the test lens 2.

[0039] like Figure 1 and Figure 4 As shown, in some embodiments, an inclined surface 53 is provided on one side of the clamp 52 close to the test lens 2, and the inclined surface 53 gradually moves away from the test lens 2 along the direction close to the substrate 1. By providing the inclined surface 53 at one end of the clamp 52 close to the test lens 2, the inclined surface 53 contacts the edge of the test lens 2, and the test lens 2 can be pressed tightly against the substrate 1, so as to achieve a test lens 2 with different thickness sizes within a certain range.

[0040] It should be noted that the thickness of the clamping block 52 is smaller than the thickness of the sliding block 51 , so as to ensure that the clamping block 52 does not contact the edge of the sliding groove 3 when the sliding block 51 slides in the sliding groove 3 .

[0041] like Figure 1 and Figure 4 As shown, in some embodiments, the clamping member 5 also includes a push-pull plate 55, and the push-pull plate 55 is integrally formed with the slider 51. The push-pull plate 55 can drive the slider 51 to slide in the slide groove 3. The push-pull plate 55 is arranged on the side of the slider 51 away from the substrate 1. When the slider 51 needs to be moved, a certain force can be applied to the push-pull plate 55, and the push-pull plate 55 drives the slider 51 to slide in the slide groove 3, thereby realizing the position adjustment of the slider 51.

[0042] It should be noted that a push-pull rod, a push-pull ring or other structures may be provided on the slider 51 to replace the push-pull plate 55 , and the configuration may be selected according to actual conditions.

[0043] like Figure 1 and Figure 3 As shown, in some embodiments, the slide groove 3 is a T-slot, and the clamping plate 54 is in sliding contact with the T-slot. By setting the T-slot, the slider 51 is in the T-slot, and the clamping plates 54 on both sides of the slider 51 respectively cooperate with the two ends of the T-slot, which can play a role of limiting and guiding the slider 51, ensuring that the slider 51 can only slide along the length direction of the T-slot.

[0044] like Figure 1 As shown, in some embodiments, the elastic member 6 includes a spring, a first end of the spring is connected to the fixing member 7, and a second end of the spring is connected to the clamping member 5. By arranging a spring between the fixing member 7 and the clamping member 5, the two ends of the spring are respectively connected to the fixing member 7 and the clamping member 5. Under the elastic force of the spring, the clamping member 5 can be ensured to be tightly attached to the test lens 2, thereby ensuring the clamping and fixing effect of the test lens 2.

[0045] It should be noted that, in other embodiments, the elastic member 6 may also be an elastic object such as an elastic strip, which can be selected according to actual conditions.

[0046] like Figure 1 As shown, in some embodiments, the fixing member 7 includes a fixing block 72 and a first fixing bolt 71, the first fixing bolt 71 passes through the fixing block 72 and is threadedly connected to the substrate 1, the fixing block 72 is connected to the substrate 1 by the first fixing bolt 71, a through hole is provided on the fixing block 72 for the first fixing bolt 71 to pass through, and a threaded groove matching the first fixing bolt 71 is provided on the base.

[0047] It should be noted that, in this embodiment, the size of the fixing block 72 is not larger than the size of the slide slot 3, and the threaded groove is provided in the slide slot 3. In other embodiments, ear pieces may be provided on both sides of the fixing block 72, and the ear pieces may be fixed to the base plate 1 by the first fixing bolts 71, and the arrangement may be made according to actual conditions.

[0048] like Figure 1 As shown, in some embodiments, the positioning portion also includes a second fixing bolt 9, and the positioning block 4 is provided with a long groove 8 for the second fixing bolt 9 to pass through. The second fixing bolt 9 passes through the long groove 8 to press the positioning block 4 on the substrate 1. By opening the long groove 8 on the positioning block 4 and opening a threaded groove matching the second fixing bolt 9 on the substrate 1, the second fixing bolt 9 passes through the long groove 8 and matches the threaded groove to press and fix the positioning block 4 on the substrate 1. When the position of the positioning block 4 needs to be moved, the second fixing bolt 9 can be loosened, and the positioning block 4 can be moved along the length direction of the long groove 8 to achieve the position adjustment of the positioning block 4.

[0049] like Figure 1 As shown, in some embodiments, two groups of second fixing bolts 9 are provided. When the second fixing bolts 9 are loosened, the positioning block 4 can slide along the direction of the long groove 8. By providing two groups of second fixing bolts 9, the two groups of second fixing bolts 9 can play a role of limiting and guiding the positioning block 4, so that the positioning block 4 can only move along the direction of the connecting line of the two groups of second fixing bolts 9 (that is, the length direction of the long groove 8).

[0050] like Figure 1 and Figure 5 As shown, in some embodiments, an arc slope 11 is provided at one end of the positioning block 4 close to the test lens 2, and an arc slope 11 is provided at the other end of the positioning block 4 close to the test lens 2. The arc slope 11 contacts the outer end of the test lens 2. The positioning block 4 can support the test lens 2 to ensure that the lens will not fall during the placement process.

[0051] See also Figure 1-Figure 5 , the following will explain the specific use of the spectrum test lens fixture:

[0052] When in use, according to the size of the test lens 2, a certain force can be applied to the push-pull plate 55, and the push-pull plate 55 drives the slider 51 to slide in the slide groove 3 to adjust the position of the slider 51 to adapt to test lenses 2 of different lengths or diameters. The clamping plate 54 and the clamping block 52 move together with the slider 51, and the slide groove 3 can play a role of limiting and guiding the clamping plate 54 to ensure that the slider 51 moves in a specific direction. The elastic member 6 is compressed, and the second fixing bolt 9 is loosened to move the positioning block 4 along the length direction of the long groove 8 to adjust the position of the positioning block 4. The position of the positioning block 4 can be adjusted according to the size of the test lens 2, so that the center of the test lens 2 is aligned with the center of the light-through hole 10 on the substrate 1 as much as possible, and the positioning block 4 can support the test lens 2. The test lens 2 is clamped and fixed to the substrate 1 at one end thereof. The inclined surface 53 is in contact with the edge of the test lens 2, so that the test lens 2 can be pressed tightly against the substrate 1 to meet the requirements of the test lens 2 with different thicknesses within a certain range. When the test is performed, the substrate 1 and the test light are perpendicular to each other, and only the test lens 2 and the substrate 1 need to be tightly attached to each other, so that the lens with a certain size range and thickness can be precisely measured.

[0053] The same or similar parts between the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the method embodiment described later, since it corresponds to the system, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.
