Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1, fig. 2 and fig. 4, an embodiment of the invention provides an optical lens edge grinding device, which includes a chassis 1, a lens changing device, a grinding changing device, a driving device and a dust removing device. The mirror changing device comprises a first rotating disc 21, a second motor 22 and a plurality of mirror holding clamps 23, the bottom of the first rotating disc 21 is rotatably connected with the inner bottom wall of the case 1 through the second motor 22, the plurality of mirror holding clamps 23 are fixed on the upper surface of the first rotating disc 21, and the plurality of mirror holding clamps 23 are uniformly arranged by taking the axis of the first rotating disc 21 as the center of a circle. The changer includes a support column 31, a second turntable 32, a third motor 33, and a plurality of sanding heads 34. One end of the supporting column 31 is fixed on the rear end face in the case 1, the bottom of the second turntable 32 is rotatably connected with the top of the supporting column 31 through a third motor 33, a plurality of through holes 36 are uniformly formed in the second turntable 32 by taking the axis as the center of circle, a first magnetic block 38 is fixed on each through hole 36, and a second magnetic block 35 is fixed on the tops of the plurality of polishing heads 34. The driving device comprises a first motor 42, a connecting rod 43 and an expansion rod 41, one end of the expansion rod 41 is fixed on the inner top wall of the case 1, the first motor 42 is fixed on the other end of the expansion rod 41, the top of the connecting rod 43 is fixedly connected with a power output shaft of the first motor 42, a clamping block 44 is arranged at the bottom of the connecting rod 43, a clamping column 37 is fixed at the top of the polishing head 34, a clamping groove 39 is formed in the top of the clamping column 37, and the clamping block 44 is clamped with the clamping groove 39. The dust removing device is arranged on the inner wall of the case 1.

Before the edging is started, the grinding heads 34 with various specifications are adsorbed on the through holes 36 of the second rotary table 32 through the second magnetic blocks 35 on the grinding heads 34, and simultaneously, the lens to be edged is clamped on the lens holding clamp 23 of the first rotary table 21. After the above preparation, the edging can be started. Since the polishing heads 34 with different specifications and models are needed for optical lenses facing different conditions, the function can be realized by replacing the polishing device. When the edge is ground, the telescopic rod 41 drives the first motor 42 to descend, so that the clamping block 44 on the connecting column reaches the clamping height. Meanwhile, the third motor 33 is started to drive the second turntable 32 to rotate, so that the polishing head 34 used for polishing the edge rotates, and the clamping groove 39 on the polishing head 34 is clamped with the connecting column through rotation. Likewise, the first rotary table 21 is rotated by the second motor 22, so that one of the lenses to be edged and the lens holder 23 holding the lens are also rotated below the connecting rod 43. The clamping block 44 at the bottom of the connecting rod 43 on the first motor 42 is clamped with the clamping groove 39 on the polishing head 34 below the clamping block. In this embodiment, the hook-shaped fixture block 44 and the fixture groove 39 are the fixture groove 39 of the hook-shaped fixture block 44 shown in fig. 5, and after the fixture block 44 reaches the clamping height, the hook-shaped fixture block 44 can be clamped into the hook-shaped fixture groove 39 by the rotation of the third motor 33. In addition, when the first motor 42 drives the polishing head 34 to rotate, the rotation direction is opposite to the initial rotation direction of the clamping groove 39, so that the polishing head 34 can not fall off in the polishing process.

After the clamping is completed, the telescopic rod 41 continues to extend downwards, so that the sanding head 34 is separated from the second turntable 32. The polishing head 34 is magnetically attached to the second rotary table 32 through the first magnetic block 38 and the second magnetic block 35, and the polishing head 34 is separated from the second rotary table 32 by the downward pushing force of the connecting rod 43. As soon as the sanding head 34 has fallen to a level at which it contacts the lens, the first motor 42 is activated, which causes the sanding head 34 to rotate and sand the corners of the lens. When the lens is finished being polished, the telescopic rod 41 drives the polishing head 34 to slightly rise, and the second motor 22 drives the first turntable 21 to rotate, so that the next lens to be polished is brought below the polishing head 34. The telescopic rod 41 again takes the polishing head 34 to descend to polish the lens.

Wherein if the sanding head 34 needs to be replaced, the telescopic rod 41 carries the sanding head 34 up until the sanding head 34 returns to the original through hole 36. At this time, the third motor 33 drives the turntable to move in the direction of the initial rotation clamping, and drives the originally connected polishing head 34 to separate from the connecting rod 43. The telescopic rod 41 continues to rise, and the third motor 33 drives the second rotary table 32 to rotate, so that the proper polishing head 34 rotates to the position below the connecting rod 43, and then the connecting rod 43 is connected with the polishing head 34 in a clamping manner. The above-mentioned processes of edging and replacing the lens with the polishing head 34 can be automatically performed by controlling the motor and the telescopic rod 41 according to a preset program. In the working mode of the device, after one lens is polished, the next lens to be polished can be conveyed to the position below the polishing head 34 by rotating the first turntable 21. Similarly, when the polishing heads 34 with different specifications need to be replaced to achieve different edging effects, the polishing heads 34 can be quickly replaced through the rotation of the second turntable 32 and the cooperation of the telescopic rods 41, so that the trouble of stopping the machine to replace the polishing heads to replace lenses in the polishing process is reduced, and the edging efficiency of the lenses is greatly improved.

In one embodiment of the present invention, the dust removing device includes two hoods 51, an exhaust fan 52, and an exhaust fan 53. The two air hoods 51 are respectively embedded on the left and right side walls of the chassis 1, the exhaust fan 52 and the exhaust fan 53 are respectively disposed on the left and right sides of the chassis 1, and the exhaust fan 52 and the exhaust fan 53 are both communicated with the adjacent air hoods 51 through air pipes. Debris is generated during the edging process and, if left on the lens, can affect the edging effect and cause insufficient edging of the lens. Therefore, at the start of edging, the suction fan 52 and the exhaust fan 53 are activated, the suction fan 52 sucks air into the cabinet 1 through the fan cover 51, and the exhaust fan 53 blows air into the cabinet 1 through the fan cover 51. When air is convected inside the cabinet 1 by suction and blowing, the chips generated by the grinding head 34 during the process of grinding the lens are carried away by the air flow in the cabinet 1. Debris is sucked from the hood 51 by the suction fan 52 and a storage tank may be additionally provided to store the debris.

In one embodiment of the present invention, the optical lens edging device further comprises a flushing device. The flushing device comprises a spray head 61, a water pump 62, a water tank 63 and a support rod. One end of the supporting rod is fixed on the side wall of the inner box, and the other end of the supporting rod extends to a position between the grinding replacing device and the mirror replacing device. The spray head 61 is fixed on the other end of the support rod, the water tank 63 and the water pump 62 are arranged outside the case 1, the input end of the water pump 62 is communicated with the bottom of the water tank 63, and the output end of the water pump 62 is communicated with the spray head 61. Even if the dust removing device is arranged, some fine debris particles can be adsorbed on the lens, and the scouring device is needed. The washing device is started after the edging is finished, the telescopic rod 41 drives the sanding head 34 to ascend, and the sanding head 34 is separated from the lens. A water pump 62 draws water from a water tank 63 and delivers the water to a spray head 61, and the spray head 61 sprays the water onto the lens to wash away debris particles attached to the lens, making the lens cleaner.

In one embodiment of the present invention, the optical lens edging device further includes a heating wire 54, and the heating wire 54 is fixed to the hood 51 connected to the exhaust fan 53. The lenses also require subsequent wiping by the operator because of the residual moisture left after rinsing. At this time, the dust removing device is turned on, and the heating wire 54 is operated. The air exhausted from the fan 53 through the hood 51 is heated by the heating wire 54 into hot air, and when the hot air blows over the lens, the residual moisture on the lens is dried, so as to accelerate the drying of the lens.

In an embodiment of the present invention, the optical lens edge grinding device further includes a liquid collecting tank 11, the liquid collecting tank 11 is fixed at the bottom of the chassis 1, a plurality of drainage holes 12 are opened on the bottom wall of the chassis 1, and the chassis 1 is communicated with the liquid collecting tank 11 through the drainage holes 12. When the lens is washed, a lot of water falls to the bottom of the box body, and the operation of the equipment is influenced if the water is stored too much. The water falling to the bottom wall of the cabinet 1 will fall to the liquid collecting tank 11 through the drainage hole 12 for storage.

As shown in fig. 3, in one embodiment of the present invention, the mirror holding clip 23 includes two vertical rods 24, two blocking plates 25, two compression springs 26, a suction cup 28 and a resisting plate 27. The two upright rods 24 are vertically arranged, the two baffle plates 25 are respectively fixed at the tops of the two upright rods 24, and the resisting plate 27 and the suction disc 28 are respectively connected to the opposite side walls of the two baffle plates 25 through the compression spring 26. When the lens is placed, the holding plate 27 and the suction cup 28 are pressed open to both sides, the lens is placed between the holding plate and the suction cup, and then both sides are released. Under the action of the compression spring 26, the suction disc 28 and the abutting plate 27 clamp the lens, and the suction disc 28 can also suck the lens, so that the lens is displaced during the edge grinding process.

In one embodiment of the present invention, the baffle 25 is provided with a rotating motor 29, and a power output end of the rotating motor 29 is fixedly connected with the compressed spring 26. The rotating motor 29 can drive the compression spring 26, the suction disc 28 at the other end of the compression spring 26 and the lens clamped by the abutting plate 27 to rotate, and each edge of the lens is conveniently polished in the edge polishing process.

In an embodiment of the present invention, an operation opening 13 is formed on a front end surface of the chassis 1, and a transparent protective cover 14 is hinged on the operation opening 13. The opening of the transparent protective cover 14 can be directly used for replacing the lens, and the respective polishing heads 34 can be directly removed to observe the wear condition of the polishing heads 34. Closing the transparent protective cover 14 during the polishing process can prevent the chips inside the case 1 from floating outwards, and can also facilitate the user to observe the situation inside the case.

In one embodiment of the present invention, the inner bottom wall of the chassis 1 is provided with a slide rail, and one end of the slide rail is connected to the operation port 13. The lower end of the second motor 22 is slidably connected to the slide rail. The first rotary disc 21 can slide forwards through the slide rail, and the part of the first rotary disc 21 and the lens holding clamp 23 slide out of the operation port 13, so that the lens can be conveniently taken and placed.

In one embodiment of the present invention, the optical lens edging device further comprises a microprocessor 71, a pressure sensor 73, a controller 74, a monitoring camera 72 and a display device 75. The pressure sensor 73, the controller 74, the monitoring camera 72 and the display device 75 are connected to the microprocessor 71, respectively. The microprocessor 71, the controller and the display device are all disposed on the top of the cabinet 1. The pressure sensor 73 is provided between the power output shaft of the first motor 42 and the connecting rod 43. The monitoring camera 72 is fixed on the inner side wall of the case 1. The pressure sensor 73 is used for sensing the pressure between the power output shaft of the first motor 42 and the connecting rod 43, sending the sensed pressure to the microprocessor 71, processing the received pressure by the microprocessor 71, sending a processing result to the controller 74, and generating a corresponding control instruction according to the processing result by the controller 74 so as to control the descending depth of the telescopic rod 41. The monitoring camera 72 is used for acquiring an environmental video in the case 1, and sending the acquired environmental video to the microprocessor 71, and the microprocessor 71 performs noise reduction processing on the received environmental video image and then sends the processed environmental video image to the display device 75 for displaying. The controller 71 is further electrically connected to the first motor 42, the second motor 22, and the third motor 33, respectively, and is configured to regulate and control the operating states of the first motor 42, the second motor 22, and the third motor 33.

After the polishing head 34 contacts with the lens, the telescopic rod 41 descends continuously, so that the polishing head 34 and the lens are squeezed, and a certain pressure exists between the polishing head 34 and the lens. Due to the fixed connection between the polishing head 34 and the connecting rod 43, the pressure measured by the pressure sensor 73 between the connecting rod 43 and the power output shaft of the first motor 42 is the pressure between the polishing head 34 and the lens. In order to ensure that the lens is not crushed by the polishing head 34 while being sufficiently polished, a pressure range suitable for polishing can be set according to lenses made of different materials. When the microprocessor 71 receives the pressure measured by the pressure sensor 73 and exceeds the maximum value of the suitable pressure range, the controller 74 controls the telescopic rod 41 to contract upwards until the measured pressure is within the pressure range suitable for polishing, and the contraction of the telescopic rod 41 is stopped. On the contrary, if the microprocessor 71 receives that the pressure measured by the pressure sensor 73 is smaller than the minimum value of the suitable pressure range, the controller 74 controls the telescopic rod 41 to extend downwards until the pressure measured by the pressure sensor 73 exceeds the pressure range suitable for sanding, and the extension of the telescopic rod 41 is stopped. Through the regulation and control mode, the lens can achieve the best polishing effect under the appropriate pressure. Meanwhile, a user can visually observe the polishing condition in the case 1 through the display device 75, and the polishing condition is conveniently controlled.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
