[0013] Technical effects and advantages of the present utility model:

[0014] 1. In the actual operation of the present utility model, when the electric push rod extends, it can drive the transparent extrusion disc to approach the positioning disc, and the lens body can be placed between the transparent extrusion disc and the positioning disc. By extrusion, the lens body is fixed. At the same time, the extrusion force can make the lens body fit on the suction cup of the positioning disc, avoiding the lens body from falling when being clamped or removed. Further, when the driving motor is started, the rotation of the driving shaft can drive the positioning disc and the transparent extrusion disc to rotate simultaneously, so that the whole lens body rotates, facilitating the personnel to observe the edges of the lens body at different angles.

[0015] 2. In addition, when the illuminating lamp inside the suction cup is started, the light can irradiate on the lens body, facilitating the personnel to observe and operate. At the same time, the transparent extrusion disc is made of transparent material, which can avoid blocking light. Since the inside of the suction cup is a conical structure, it can be used to diffuse and magnify the light, and the illumination can facilitate the personnel to check the refractive index and transparency of the lens body.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a positioning device for optical lens processing as shown in Figure 1 - Figure 2 Figure 1, which includes a workbench 1. On both sides of the top of the workbench 1, a moving seat 3 and a fixed seat 4 are respectively arranged. The moving seat 3 and the fixed seat 4 are arranged in parallel. An electric slide rail 2 is embedded in the top of the workbench 1. A slider is slidably engaged with the electric slide rail 2. The bottom end of the moving seat 3 is fixed to the slider. The fixed seat 4 is fixedly connected to the top of the workbench 1.

[0021] In the actual operation of the present invention, by starting the electric slide rail 2, the slider can drive the moving seat 3 to move, so that the moving seat 3 approaches or moves away from the fixed seat 4, facilitating the adjustment of the clamping distance.

[0022] A displacement sensor 12 and an alarm are embedded on the side of the moving seat 3 close to the fixed seat 4. The displacement sensor 12 can detect the distance between the moving seat 3 and the fixed seat 4 in real time. When the distance is too close, the displacement sensor 12 can transmit a signal to the controller, and the controller controls the alarm to give an alarm to avoid insufficient clamping space due to too close a distance.

[0023] An electric push rod 5 and a driving motor 8 are respectively fixedly connected to the sides of the moving seat 3 and the fixed seat 4 away from each other. One end of the electric push rod 5 passes through the moving seat 3, and the passing end is rotatably connected to a transparent pressing disc 6. The driving shaft of the driving motor 8 passes through the fixed seat 4, and the passing end of the driving shaft is fixedly connected to a positioning disc 9. A lens body 7 is clamped between the positioning disc 9 and the transparent pressing disc 6. The positioning disc 9 and the transparent pressing disc 6 are at the same height.

[0024] The positioning disc 9 and the transparent pressing disc 6 are arranged opposite to each other. A suction cup 10 is fixed on the side of the positioning disc 9 close to the transparent pressing disc 6. A plurality of lighting lamps 11 are arranged inside the suction cup 10. The plurality of lighting lamps 11 are embedded in the positioning disc 9.

[0025] In the actual operation of the utility model, the electric push rod 5 extends, which can drive the transparent extrusion disc 6 to approach the positioning disc 9. The lens body 7 can be placed between the transparent extrusion disc 6 and the positioning disc 9. By means of extrusion, the lens body 7 is fixed. At the same time, the extrusion force can make the lens body 7 fit on the suction cup 10 of the positioning disc 9, avoiding the dropping of the lens body 7 when it is clamped or removed. Further, when the driving motor 8 is started, the rotation of the driving shaft can drive the positioning disc 9 and the transparent extrusion disc 6 to rotate simultaneously, so that the whole lens body 7 rotates, facilitating the personnel to observe the edges of the lens body 7 at different angles.

[0026] In addition, when the lighting lamp 11 inside the suction cup 10 is started, the light can irradiate on the lens body 7, facilitating the personnel to observe and operate. At the same time, the transparent extrusion disc 6 is made of transparent material, which can avoid blocking the light. Since the suction cup is in a conical structure, it can be used to diffuse and magnify the light.

[0027] A layer of transparent silica gel pad is fixedly connected to the side of the transparent extrusion disc 6 close to the suction cup 10. The radius of the transparent silica gel pad is smaller than that of the transparent extrusion disc 6. The transparent silica gel pad plays a role in protecting and buffering the lens body 7.

[0028] The radius of the transparent extrusion disc 6 is the same as that of the positioning disc 9. Anti-slip feet are fixed at the four corners of the bottom end of the workbench 1 to avoid slipping.
