Detailed Description

As shown in fig. 1, the lens edge trimmer comprises a case 1, wherein a rotating motor 2 is mounted at the bottom of the case 1, a rotating disc 3 is mounted on an output shaft of the rotating motor 2, and the rotating motor 2 is used for driving the rotating disc 3 to rotate. The surface of carousel 3 is provided with constant head tank 4, and constant head tank 4 is used for supporting and fixes a position lens 8, and lens 8 is arranged in constant head tank 4 and lens 8's edge is outside protrusion in constant head tank 4. The turntable 3 is internally provided with a cavity, the cavity is internally provided with a vacuum generator 5, the vacuum generator 5 is connected with an external power supply, the positioning groove 4 of the turntable 3 is internally provided with a plurality of suction holes 6 at intervals, the vacuum generator 5 is respectively communicated with the suction holes 6 through pipelines, the lens 8 can be adsorbed and fixed in the positioning groove 4 by starting the vacuum generator 5, the displacement phenomenon of the lens 8 in the positioning groove 4 during trimming is avoided, and the trimming precision is ensured.

As shown in fig. 1 and fig. 2, a limiting block 7 is fixedly mounted on the left side of the lens 8 in the case 1, the limiting block 7 can abut against the left edge of the lens 8, and when the lens 8 is placed in the positioning groove 4, the lens 8 abuts against the limiting block 7 to the left side, so that the lens 8 can be positioned quickly.

As shown in fig. 1, a supporting plate 9 is installed on the rear side wall of the chassis 4, and a space is left between the supporting plate 9 and the upper surface of the lens 8, so that the supporting plate 9 is not in contact with the rotating lens 8, and the abrasion of the lens surface is avoided. At least two guide posts 10 are vertically arranged on the support plate 9, a compression spring 11 is sleeved on each guide post 10, a guide block 12 is further arranged on each guide post 10, each guide block 12 is pressed on the compression spring 11, each guide block 12 can move up and down along each guide post 10, a trimming knife 14 is fixed at the bottom of each guide block 12, a through hole for the trimming knife 14 to penetrate through is formed in the support plate 9, and the guide blocks 12 are pressed downwards to enable the trimming knives 14 to penetrate through the through holes and then rub the lenses 8 from the edges of the right sides of the lenses 8 to trim the lenses. The matching structure of the supporting plate 9, the guide post 10 and the guide block 12 ensures that the trimming knife 14 is not easy to vibrate or deflect when being subjected to the reverse acting force of the edge of the lens, and is beneficial to stably trimming the lens 8 by the trimming knife 14. After trimming, the compression spring 11 can automatically jack up the guide block 12, so that the trimming knife 14 retracts into the supporting plate 9 and does not contact the lens 8 any more, and at the moment, the right side of the lens 8 loses the limiting structure, and the lens 8 can be conveniently and quickly taken away. And limiting beams 13 are fixedly arranged at the tops of the two guide columns 10, and the limiting beams 13 are used for limiting the upward movement stroke of the guide block 12 and preventing the guide block 12 from being separated from the guide columns 10 from the tops of the guide columns 10.

In order to operate the guide block more easily, a knife pressing cylinder 15 is installed at the top of the case 1, the knife pressing cylinder 15 is located right above the guide block 12, a piston rod of the knife pressing cylinder 15 is fixedly connected with the guide block 12, the knife pressing cylinder 15 is started to press the guide block 12 downwards, the trimming knife 14 extends out of the through hole in the support plate downwards, and a rod hole for the piston rod of the knife pressing cylinder 15 to penetrate through is formed in the limiting cross beam 13. At this time, the edge trimming blade 14 may be moved up and down only by the blade pressing cylinder 15 without installing the compression spring 11.

The working process of the device is as follows: the lens 8 is placed on the positioning groove 4, the left edge of the lens is pressed against the limiting block 7, the guide block 12 is pressed downwards, the trimming knife 14 extends downwards out of the supporting plate 9 to be pressed against the right edge of the lens 8, and then the vacuum generator 5 is started to adsorb and fix the lens 8, so that the lens 8 is accurately fixed on the positioning groove 4. Then, the rotary motor 2 is started to rotate the turntable 3 and the lens 8, and the lens 8 is edged by the edging blade 14.
