It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0027] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0028] The embodiment of the utility model provides a lens finish detection fixture 100.

[0029] See also Figures 1 to 3 The lens finish detection fixture 100 includes a support member 110, a clamping assembly 120 and a rotating handle 130; the clamping assembly 120 is used to clamp and fix the lens, the clamping assembly 120 is connected to the support member 110 in a horizontal rotation direction, and the rotating handle is connected to the clamping assembly 120 for driving the clamping assembly 120 to rotate.

[0030] It is understandable that the technical solution of the utility model provides a lens finish detection fixture 100, wherein the clamping assembly 120 is used to clamp and fix the lens (not shown), the clamping assembly 120 is connected to the support member 110 in a horizontal rotation direction, and the rotating handle is connected to the clamping assembly 120 to drive the clamping assembly 120 to rotate; after the operator places the lens on the clamping assembly 120 and fixes the clamping assembly 120, under the illumination of an external light source, the operator manually shakes the rotating handle 130 to drive the clamping assembly 120 to rotate, so as to fully observe the finish of the lens and select lenses that meet or do not meet the finish requirements. Therefore, by using the above-mentioned lens finish detection fixture 100, in the process of detecting the finish of the lens, the rotation law of the lens is consistent, so that the visual experience of different operators or the same operator detecting different batches of lenses is also similar, thereby improving the stability of the lens finish detection quality.

[0031] It should be noted that the rotating handle 130 can be replaced by a driving motor.

[0032] See also Figure 1 and Figure 2 , in one embodiment, the clamping assembly 120 includes a fixing frame 121;

[0033] The two ends of the fixing frame 121 are provided with shaft protrusions 1211, and the supporting member 110 has a matching portion, and the shaft protrusions 1211 are rotatably matched with the matching portion, wherein at least one shaft protrusion 1211 is connected to a rotating handle 130;

[0034] Compared with providing a protruding structure on the support member 110 , the cooperation between the shaft protrusion 1211 and the matching portion can improve the rotation stability of the fixing frame 121 .

[0035] Optionally, the matching portion is a circular hole, and the shaft protrusion 1211 passes through the support member 110 and is threadedly connected to the fixing frame 121 and is rotationally matched with the circular hole.

[0036] Optionally, one of the mating portions mating with the shaft protrusion 1211 is a circular groove.

[0037] Please continue reading Figure 2 or Figure 3 In a specific embodiment, the clamping assembly 120 further includes a movable frame 123 and a spring 124;

[0038] The fixed frame 121 is also provided with a guide member 1212, and the guide member 1212 is perpendicularly arranged relative to the extension direction of the shaft protrusion 1211. The movable frame 123 passes through the guide member 1212 and is used to cooperate with the fixed frame 121 to fix the lens; one end of the guide member 1212 has a stopper 1212a, and the spring 124 is sleeved on the guide member 1212 and is located on the side of the movable frame 123 away from the fixed frame 121, and the stopper 1212a is used to prevent the spring 124 from detaching from the guide member 1212.

[0039] Specifically, in one embodiment, the spring 124 is sleeved on the guide member 1212 and is close to the blocking portion 1212 a . The other end of the guide member 1212 passes through the movable frame 123 and is threadedly connected to the fixed frame 121 .

[0040] When the lens is clamped and fixed, the spring 124 contracts. At this time, the spring 124 has the potential energy of expansion, so that the movable frame 123 abuts against the fixed lens.

[0041] See also Figure 2 In one embodiment, the fixing frame 121 is further provided with a plurality of object carriers 1213, which are arranged in an array at equal intervals along the length direction of the fixing frame 121, and the guide member 1212 is fixedly connected to the object carriers 1213. It can be understood that the arrangement of the object carriers 1213 enables the clamping assembly to stably clamp a plurality of lenses at one time for batch testing, thereby improving the testing efficiency.

[0042] Please continue reading Figure 2 or Figure 3 On the basis of the above embodiment, the clamping assembly 120 also includes a push rod 126; the fixed frame 121 is also provided with a first mounting seat 1214, and the movable frame 123 is provided with a second mounting seat 1231. The push rod 126 passes through the first mounting seat 1214 and is connected to the second mounting seat 1231. The push rod 126 is slidably connected to the first mounting seat 1214, and the second mounting seat 1231 and the push rod 126 are fixed axially relative to the push rod 126.

[0043] It is understandable that the second mounting seat 1231 and the push rod 126 can be welded, or integrally formed, or the push rod 126 can be threadedly connected to the second mounting seat 1231. The push rod 126 is slidably connected to the first mounting seat 1214. Since the fixed frame 121 is relatively fixed, when the lens needs to be unloaded, the movable rod is pushed in the direction close to the movable frame 123, and the movable frame 123 overcomes the potential energy of the expansion when the spring 124 contracts, and moves in the direction away from the fixed frame 121, so that the lens falls to the workbench.

[0044] Optionally, the push rod 126 and the second mounting seat 1231 may also be interference fit to drive the movable frame 123 to move.

[0045] Optionally, in order to avoid damaging the lens when clamping it, the movable frame 123 is further provided with a flexible member 1232 on one side close to the fixed frame 121, and when the lens is fixed, the flexible member 1232 contacts the lens. Optionally, the flexible member 1232 is a rubber pad or a silicone pad or a cloth.

[0046] In one embodiment, a dust removal component (not shown) is further included, the dust removal component includes a micro fan and a driving motor for driving the micro fan, the micro fan and the driving motor are arranged inside the fixed frame 121, and an air duct is formed in the extension direction inside the fixed frame 121, the fixed frame 121 has an air inlet (not shown) on the side away from the movable frame 123, and the fixed frame 121 has an air outlet on the side close to the movable frame 123; and a dust removal filter is arranged at the air inlet. Further, the air outlet 121a is arranged on both sides of the lens, and the air outlet 121a is used to clean the dust on the surface of the lens and prevent dust from falling on the surface of the lens.

[0047] It is understandable that the dust removal filter is configured to filter dust in the air. Optionally, the dust removal filter is made of fiber material, such as a HEPA filter.

[0048] Optionally, in order to improve the dust removal effect on the lens, two dust removal components are provided, and the two dust removal components are arranged at both ends of the air duct.

[0049] See also Figure 1 In a preferred embodiment of the present invention, it further includes an operating platform 140 and a lamp holder 150 , wherein the support member 110 is disposed on the operating platform 140 , and the lamp holder 150 is fixed to the operating platform 140 .

[0050] It can be understood that the lamp holder 150 is used to install the light source. The setting of the lamp holder 150 limits the position of the light source relative to the clamping assembly 120, reduces the changes in environmental factors, and further improves the stability of the lens finish detection quality.

[0051] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
