Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1-4, the utility model discloses a lens 50 edging device, it includes: a controller, a grinding mechanism, a clamping and rotating mechanism, a displacement mechanism and at least one control button 40. The controller can be a PLC.

The displacement mechanism is used for driving the clamping and rotating mechanism to move relative to the polishing mechanism and comprises a sliding frame 11, two sliding rails 12 and a pushing cylinder 13, wherein the sliding rails 12 are fixed on the mounting platform 60, the two sliding rails 12 are parallel to each other and are arranged obliquely, the oblique direction of the sliding rails 12 faces the polishing mechanism, and the sliding frame 11 is connected to the sliding rails 12 in a sliding manner. Under the condition that the sliding frame 11 is not blocked by foreign objects or external force, the sliding frame 11 automatically slides downwards along the inclined direction of the sliding rail 12 under the action of self gravity. In order to ensure smooth sliding, lubricating oil may be applied to the slide rail 12. In addition, a counter weight may be provided on the carriage 11 to ensure the sliding movement of the carriage 11, or an elastic member, such as a spring, may be provided, one end of which is fixed to the carriage 11 and the other end of which is fixed to the polishing mechanism or the mounting platform 60, so that the sliding movement of the carriage 11 toward the polishing mechanism is promoted by the tensile force of the elastic member.

The arrangement of the pushing cylinder 13 is used for pushing the sliding frame 11 towards the direction far away from the polishing mechanism, so that the lenses 50 can be replaced conveniently, and the safety of manually feeding the lenses 50 is ensured. The pushing cylinder 13 is connected with the controller. The pedestal of push cylinder 13 is fixed to be set up on mounting platform 60, and when the push rod of push cylinder 13 stretched out, this push rod and carriage 11 butt to promote carriage 11 and keep away from grinding machanism, and when the push rod of push cylinder 13 completely contracted, this push rod contactless carriage 11.

The clamping and rotating mechanism is arranged on the sliding frame 11 and comprises a first clamping piece 21, a second clamping piece 22, a rotating driving piece 23 and a linear driving piece 25, wherein the first clamping piece 21 and the second clamping piece 22 are both of a structure with a circular section. The first clamping member 21 is rotatably connected to one side of the sliding frame 11 through a bearing, a limiting sleeve 111 is fixed to one side of the sliding frame 11 opposite to the first clamping member 21, the second clamping member 22 is slidably connected to the limiting sleeve 111, and meanwhile, the second clamping member 22 can also rotate in the limiting sleeve 111. The linear driving member 25 is a pneumatic cylinder, the seat thereof is fixed on the sliding frame 11, the push rod thereof is rotatably connected with the second clamping member 22, and the second clamping member is driven by the linear driving member 25 to move toward or away from the first clamping member 21. The stability of the second clamping part 22, especially in the case of rotation, is ensured by the provision of the stop collar 111, and the linear drive 25 is also protected to a certain extent. The rotary driving member 23 is a motor, and its seat is fixed on the sliding frame 11, and its output shaft is connected with the first clamping member 21 through a belt or a chain or a gear. The linear drive 25 and the rotary drive 23 are both connected to the controller.

The first clamping member 21 and the second clamping member 22 are used for clamping and fixing the lens 50 in a matching way, wherein a concave contact surface 211 matched with the convex surface of the lens 50 is arranged on the first clamping member 21, and a convex contact surface 221 matched with the concave surface of the lens 50 is arranged on the second clamping member 22. Through setting up concave contact surface 211 and convex contact surface 221, can increase the area of contact with lens 50 for when first holder 21 and second holder 22 centre gripping fixed lens 50, lens 50 atress is more balanced, avoids lens 50 impaired, and lens 50 also can the centre gripping more stable simultaneously, is difficult for getting rid of and flies.

Grinding machanism sets up on mounting platform 60, including fixing base 31, grinding drum 32 and grinding motor 33, and grinding drum 32 rotates to be connected on fixing base 31, and grinding motor 33 passes through belt or chain or gear drive with grinding drum 32 to be connected, and grinding drum 32's surface is the frosting. The grinding motor 33 is connected with the controller.

The control button 40 may be provided on the mounting platform 60 at a position easily accessible to the operator. Control buttons 40 are connected to the controller for controlling: the integral emergency stop of the device, the feeding and polishing of the lens 50 and the like. In the present case, include three control button 40, be scram button, material loading button and polish button respectively. After the device starts up, press the material loading button, grinding machanism and rotary driving piece 23 do not operate, push cylinder 13 action, make carriage 11 keep away from grinding machanism, linear driving piece 25 moves simultaneously, make first holder 21 and second holder 22 separate a distance, can place lens 50 between first holder 21 and second holder 22 this moment, then press the button of polishing, push cylinder 13 action, make first holder 21 and second holder 22 press from both sides lens 50 tight fixed, then push cylinder 13 retracts, no longer block carriage 11 and slide, carriage 11 relies on the natural fall to be close to grinding machanism, grinding machanism operates simultaneously. When the sliding frame 11 approaches the polishing mechanism, the rotary driving member 23 rotates to slowly rotate the lens 50, so as to polish off the redundant polarizing film at the edge of the lens 50. Because of the fit relationship of carriage 11 with slide rail 12, and the self weight of carriage 11, the edge of lens 50 is able to always abut the frosted surface of grinding drum 32. In addition, since the sliding frame 11 is slidable on the sliding rail 12, the lens 50 can be polished without centering, and when the lens 50 is not centered, the sliding frame 11 is adapted to slide on the sliding rail 12 according to the distance from the tangent point position of the lens 50 and the polishing roller 32 to the rotation center of the lens 50, as shown in fig. 5 to 6.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
