DETAILED DESCRIPTION
[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0036] Example 1: Please refer to Figure 1-Figure 4 When the existing flaw detection machine performs flaw detection on the lens, it is not convenient to place and position multiple lenses at the same time, which leads to low overall detection efficiency. In order to solve this technical problem, the present embodiment discloses the following technical content: a surface flaw detection machine for eyeglass lenses, comprising a positioning back plate 1, a servo motor 2 is fixedly connected to the middle of the back of the positioning back plate 1, and a movable disk 3 is connected to the output end of the servo motor 2, and a receiving groove 4 is provided on the movable disk 3 for placing the eyeglass lenses to be detected; a limiting mechanism 5 is installed inside the receiving groove 4 for fixing the lenses placed inside the receiving groove 4; there are multiple receiving grooves 4 evenly distributed at equal angles on the movable disk 3, and a limiting mechanism 5 is installed inside each receiving groove 4. The limiting mechanism 5 includes a clamping block 501, and the clamping block 501 is located inside the receiving groove 4, and the clamping block 501 is connected to the inside of the movable disk 3 through a reset spring 502. The end of the clamping block 501 is set as an arc structure, and the clamping block 501 forms an elastic telescopic structure through the reset spring 502 and the movable disk 3.
[0037] When it is necessary to test the eyeglass lens, push the clamp 501 toward the outside of the receiving groove 4, place the lens to be tested in the receiving groove 4, release the clamp 501, and the clamp 501 will return to its original position under the action of the return spring 502. The reset clamp 501 fixes the lens to ensure the stability of the lens in the receiving groove 4. At the same time, the receiving grooves 4 are evenly distributed on the movable plate 3. By using the evenly distributed receiving grooves 4, multiple lenses can be placed on the movable plate 3, which is convenient for subsequent one-by-one testing.
[0038] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. When the existing lens is tested, it is not convenient to clean the dust and impurities attached to the surface of the lens, which leads to a large amount of impurities attached to the lens, which easily affects the accuracy of the final lens flaw detection result. Figure 1 and Figure 6 As shown, in order to solve this technical problem, the present embodiment discloses the following technical contents: a connecting frame 6 is fixedly connected to the middle of the upper end of the positioning back plate 1, and flaw detectors 7 are installed on both the front and rear sides of the connecting frame 6; a clamping frame 8 is fixedly connected to the middle of the lower end of the positioning back plate 1, and cleaning bristles 9 are fixedly connected to both the front and rear sides of the clamping frame 8;
[0039] When the lenses are fixed on the movable disk 3 in sequence, the servo motor 2 is turned on. After the servo motor 2 is turned on, the movable disk 3 can be rotated. The rotation of the movable disk 3 can drive the lenses thereon to rotate synchronously, so that the lenses pass through the cleaning bristles 9 on the inner side of the clamping frame 8. The cleaning bristles 9 are used to clean impurities and dust attached to the surface of the lenses. When the impurities after cleaning pass through the flaw detector 7 on the inner side of the connecting frame 6, the flaw detector 7 is used to perform flaw detection and measurement on the surface of the lenses.
[0040] Embodiment 3: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiments 1 and 2. The existing lens flaw detection equipment cleans the attachments on the lens surface by setting corresponding brushes. However, after cleaning the lens, the impurities on the lens surface are easily attached to the cleaning brush. When the cleaning brush is attached with a lot of impurities, it is easy to make them re-attach to the surface of the lens during subsequent lens cleaning. Figure 1 and Figure 6As shown, in order to solve this technical problem, the present embodiment discloses the following technical contents: the movable disk 3 is circumferentially fixedly connected with a first magnetic block 10, the first magnetic block 10 is used to generate magnetic force on the self-cleaning mechanism 11, and the self-cleaning mechanism 11 is installed on the clamping frame 8, and the dust attached to the cleaning bristles 9 is shaken off by vibration. The self-cleaning mechanism 11 includes an adjustment frame 111, and the adjustment frame 111 is installed on the clamping frame 8, and the end of the adjustment frame 111 located outside the clamping frame 8 is fixedly connected with a striking block 112, and the adjustment frame 111 is connected to the clamping frame 8 through an auxiliary spring 113, and the side of the adjustment frame 111 located inside the clamping frame 8 is fixedly connected with a second magnetic block 114. The striking blocks 112 are evenly distributed on the adjustment frame 111, and the striking blocks 112 are mutually attached to the clamping frame 8 in the initial state, and the adjustment frame 111 can slide on the clamping frame 8. The second magnetic blocks 114 have the same magnetic properties as the first magnetic blocks 10 , and the first magnetic blocks 10 are evenly distributed in the circumferential direction of the movable disk 3 .
[0041] When the movable disk 3 rotates, the first circumferential magnetic block 10 can rotate synchronously with it. When the first magnetic block 10 rotates and approaches the second magnetic block 114 on the adjusting frame 111, the repulsive magnetic force between the two can make the adjusting frame 111 move toward the outside of the clamping frame 8. After the adjusting frame 111 moves, the striking block 112 thereon moves synchronously to the outside of the clamping frame 8. When the movable disk 3 continues to rotate, the first circumferential magnetic block 10 and the second magnetic block 114 on the adjusting frame 111 move away from each other, the adjusting frame 111 resets and rebounds under the action of the auxiliary spring 113. After the adjusting frame 111 resets, the striking block 112 thereon hits the clamping frame 8. The vibration generated by the impact on the clamping frame 8 can be used to shake off the dust attached to the cleaning bristles 9, thereby ensuring the cleanliness of the cleaning bristles 9.
