[0002] Nowadays, glass lenses are widely used, such as cameras in surveillance cameras, cameras on mobile phones, cameras on cameras, cameras on projectors, lenses of glasses, magnifying glasses for teaching or experiments, etc., all of which require glass lenses.

[0003] The main raw material of glass lenses is optical glass, which has excellent optical properties, is not easy to scratch, has a high refractive index, has good light transmittance and mechanical and chemical properties, has a constant refractive index, and stable physical and chemical properties. When processing glass lenses, it is often necessary to manually grind the edges of the glass lenses to ensure the neatness of the edges and corners of the glass lenses. However, the existing manual edge grinding of glass lenses not only increases manual labor, but also reduces the processing efficiency of glass lenses.

[0004] The fully automatic lens edge grinding machine currently in use includes a template fixing device, a lens locking and clamping device, a grinding wheel, an automatic sensing device, a program control board and an operating platform. However, before the glass lens is clamped, the glass lens needs to be protected.

DETAILED DESCRIPTION

[0064] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0065] Reference Figures 1 to 11 As shown, a fully automatic edge grinding device for glass lenses comprises:

[0066] The lens protection device 1 is used to prepare the protection work before the glass lens 2 is processed;

[0071] The first protective mechanism is used to attach the suction cup 8 to one side of the glass lens 2, and the first protective mechanism includes a lens supporting plate 6, a suction cup supporting plate 7 arranged on one side of the lens supporting plate 6, and a clamping mechanism arranged above the lens supporting plate 6 and the suction cup supporting plate 7;

[0072] The second protective mechanism is used to stick the transparent sticker 9 on the other side of the glass lens 2, and the second protective mechanism includes a sticker positioning plate 10, a pressing mechanism arranged above the sticker positioning plate 10, and a suction mechanism arranged below the sticker positioning plate 10;

[0073] A material storage plate 57 for holding the processed glass lens 2 is provided on the side of the gripping device 4 .

[0074] Before the operator processes the glass lens 2, first, the operator places a number of unprocessed glass lenses 2 on the lens holding plate 6, and places a number of suction cups 8 on the suction cup holding plate 7. Then, the clamping mechanism places the glass lens 2 on the protective table 3. After the glass lens 2 is placed, the clamping mechanism then attaches the suction cup 8 to the upward side of the glass lens 2. When the transparent sticker 9 is attached to the other side of the glass lens 2, the pressing mechanism and the suction mechanism are driven synchronously, and the pressing mechanism presses the transparent sticker 9 on the patch in the patch positioning plate 10 off the patch, and the suction mechanism is sucked. The mechanism simultaneously absorbs the pressed transparent sticker 9, with the adhesive surface of the transparent sticker 9 facing upwards, and the transparent sticker 9 is then attached to the glass lens 2 through the absorption mechanism. After the protection work of the glass lens 2 is completed, the grasping device 4 grasps the glass lens 2 in the lens edger 5, and the lens edger 5 finally performs edge grinding on the glass lens 2. Finally, the processed glass lens 2 is placed in the material storage plate 57 by the grasping device 4 to be taken by the operator. The present invention reduces manual labor and improves the protection efficiency and edge grinding efficiency of the lens through the automatic operation of the lens protection device 1.

[0075] The lens receiving plate 6 is arranged on a receiving platform 11, and a square groove 12 for positioning the lens receiving plate 6 is provided on the top of the receiving platform 11, and a lifting opening for facilitating taking out the lens receiving plate 6 is provided on one side of the lens receiving plate 6, and a plurality of lens receiving openings 13 for placing the lens receiving plate 6 are provided at equal intervals on the top of the lens receiving plate 6, and a chamfered opening for grabbing the glass lens 2 is provided at the edge of each lens receiving opening 13.

[0076] When the glass lens 2 is placed in the lens receiving opening 13 on the lens receiving plate 6, a reserved opening for grabbing the glass lens 2 is reserved through the chamfered opening 13, which facilitates the clamping mechanism to clamp the glass lens 2. After all the glass lenses 2 on the lens receiving plate 6 are taken out, the operator can take out the lens receiving plate 6 for loading.

[0077] The suction cup supporting plate 7 is located between the lens supporting plate 6 and the protective platform 3. The top of the suction cup supporting plate 7 is provided with a plurality of suction cup placement openings 14 for placing suction cups 8. The top of the protective platform 3 is provided with a placement opening 15 for supporting the glass lens 2. The bottom of the protective platform 3 is also provided with a mounting opening 16 for mounting the transparent sticker 9.

[0078] When the suction cups 8 are placed, several suction cups 8 are placed by the operator in the suction cup placement opening 14 of the suction cup supporting plate 7. After the glass lens 2 is placed in the placement opening 15 of the protective table 3, the suction cups 8 are attached to the upward side of the glass lens 2, and the transparent sticker 9 is attached to the downward side of the glass lens 2 through the attachment opening 16.

[0079] The gripping mechanism comprises: a first finger cylinder 17 and a gripping drive mechanism 18;

[0080] The clamping drive mechanism 18 is disposed on a rectangular platform 19 and has a movable frame 20 that moves horizontally along the length direction of the rectangular platform 19. The movable frame 20 is also provided with a movable block 21 that moves horizontally along the length direction thereof.

[0081] The first finger cylinder 17 is vertically movable and is disposed on the moving block 21. The clamping finger of the first finger cylinder 17 is disposed downward and is installed in a housing. Each clamping finger of the first finger cylinder 17 is also provided with a clamping opening 22 for clamping the hexagonal protrusion end of the suction cup 8.

[0082] A double-shaft double-rod cylinder 23 is provided on the moving block 21 and can drive the first finger cylinder 17 to move vertically.

[0083] When placing the glass lens 2, the first finger cylinder 17 moves downward through the double-axis double-rod cylinder 23 to grab the glass lens 2, the moving frame 20 drives the first finger cylinder 17 to move horizontally toward the protective table 3, and the moving block 21 drives the first finger cylinder 17 to adjust the grabbing direction, and the glass lens 2 is then placed in the placement opening 15 on the protective table 3 by the clamping fingers of the first finger cylinder 17.

[0084] The moving direction of the moving frame 20 is perpendicular to the moving direction of the moving block 21. A first avoidance opening 24 is provided on both sides of the placement opening 15 of the protective platform 3 for facilitating the first finger cylinder 17 to place the glass lens 2. A first photoelectric sensor 25 with its output end facing upward is also provided on the top of the protective platform 3, and a first sensing head 26 for sensing with the first photoelectric sensor 25 is also provided on the outer shell of the first finger cylinder 17.

[0085] When the first finger cylinder 17 accurately places the glass lens 2 in the placement opening 15 on the protective table 3, the first photoelectric sensor 25 senses the first sensing head 26, which is conducive to the accurate placement of the glass lens 2 and prevents the transparent sticker 9 from being unable to stick on the glass lens 2 through the mounting opening 16. In addition, the two first avoidance openings 24 on the protective table 3 do not hinder the first finger cylinder 17 from placing the glass lens 2.

[0086] The patch positioning plate 10 is provided with a placement groove 27, and the upper and lower surfaces of the patch positioning plate 10 are through-shaped. A patch is laid in the placement groove 27, and a plurality of pressure holes 28 are provided on the patch. A transparent patch 9 is also affixed to the downward side of the patch and at each pressure hole 28. The size of each transparent patch 9 is larger than the size of the pressure hole 28. A pressing plate 29 is provided on both sides of the patch positioning plate 10 located inside the placement groove 27 so as to be able to move vertically, and a screw 30 for driving the pressing plate 29 to move vertically is also provided on the patch positioning plate 10, and a knob 31 is provided at the end of the screw 30 for the convenience of the operator to turn.

[0087] Before attaching the transparent sticker 9, several transparent stickers 9 are attached to a whole patch, and the patch is placed in the placement groove 27, with the unattached parts of several transparent stickers 9 facing downward. Then, the operator manually rotates the screw 30 through the knob 31, and the two pressing plates 29 press the two sides of the patch to prevent the patch from moving when the transparent sticker 9 is absorbed, thereby preventing the transparent sticker 9 from being absorbed.

[0088] The pressing mechanism comprises: a pressing rod 32 and a first horizontal linear driver 33;

[0089] The first horizontal linear driver 33 is horizontally arranged on one side of the patch positioning plate 10, and has a first mounting block 34 that moves horizontally along the wall direction of the patch positioning plate 10. A first push rod 35 is horizontally arranged on the first mounting block 34, and the pushing direction of the first push rod 35 is perpendicular to the moving direction of the first mounting block 34.

[0090] The lower pressing rod 32 is vertically arranged on the output end of the first push rod 35 , and a pressing head 36 is provided at the downward end of the lower pressing rod 32 for pressing out the transparent sticker 9 on the patch, and the diameter of the pressing head 36 is at least smaller than the diameter of the pressing port 28 .

[0091] When the transparent sticker 9 is removed from the patch, the lower pressing rod 32 drives the pressing head 36 to pass through the pressing port 28 to remove the transparent sticker 9 from the patch. Since the pressing head 36 is a non-sticking part, the transparent sticker 9 will not stick to the pressing head 36. The lower pressing rod 32 can remove the transparent stickers 9 in all positions through the movement of the first mounting block 34 and the movement of the first push rod 35.

[0092] The suction mechanism includes: a resistance rod 37 and a second horizontal linear drive 38;

[0093] The second horizontal linear driver 38 is horizontally arranged at the bottom of the suction cup supporting plate 7, and has a second mounting block 39 that moves horizontally along the moving direction of the first mounting block 34. A second push rod 40 is horizontally arranged on the second mounting block 39, and the pushing direction of the second push rod 40 is perpendicular to the moving direction of the second mounting block 39 and parallel to the pushing direction of the first push rod 35.

[0094] The resistance rod 37 is vertically arranged on the output end of the second push rod 40. The end of the resistance rod 37 facing the patch positioning plate 10 is provided with a suction plate 41 for sucking the transparent patch 9, and the suction plate 41 is elastically connected to the end of the resistance rod 37 through a buffer spring 42.

[0095] When the transparent sticker 9 is removed, the resistance rod 37 is pressed against the bottom of the sticker through the suction plate 41. After the transparent sticker 9 is pressed down, it is sucked by the suction plate 41. Through the action of the buffer spring 42, when the transparent sticker 9 is pressed down, the suction plate 41 is under pressure to suck the transparent sticker 9 and has a buffering effect downward.

[0096] A second photoelectric sensor 43 with its output end facing downward is disposed on the top of the protection platform 3 , and a second sensing head 44 for sensing by the second photoelectric sensor 43 is also disposed on the output end of the abutment rod 37 .

[0097] When the transparent sticker 9 is attached to the glass lens 2, the resistance rod 37 moves to the bottom of the mounting opening 16 through the second mounting block 39 and the second push rod 40, and the second photoelectric sensor 43 senses the second sensing head 44, so that the transparent sticker 9 can be accurately attached to the glass lens 2 through the mounting opening 16.

[0098] The grasping device 4 includes a multi-axis manipulator 45, a rotatable frame 46 is provided at the output end of the multi-axis manipulator 45, a rotatable second finger cylinder 47 is provided on the frame 46, a first rotating motor 48 that can drive the frame 46 to rotate is provided at the output end of the multi-axis manipulator 45, a second rotating motor 49 that can drive the second finger cylinder 47 to rotate is provided on the frame 46, and the rotation direction of the frame 46 is perpendicular to the rotation direction of the second finger cylinder 47, and a second avoidance opening 50 is provided on both sides of the placement opening 15 of the protective platform 3 for the second finger cylinder 47 to grasp the glass lens 2.

[0099] When the protection work of the glass lens 2 is completed, the second finger cylinder 47 grabs the glass lens 2 through the two second avoidance openings 50, and the second finger cylinder 47 is rotated 180° by the second rotating motor 49, so that the suction cup 8 on the glass lens 2 faces downward, and the multi-axis manipulator 45 drives the second finger cylinder 47 to move into the lens edge grinding machine 5, and the first rotating motor 48 adjusts the direction so that the glass lens 2 is accurately located in the appropriate position.

[0100] The lens edge grinder 5 includes a housing 51, in which are disposed a first clamping rod 52 and a second clamping rod 53 for clamping and driving the glass lens 2 to rotate. The first clamping rod 52 and the second clamping rod 53 are symmetrically arranged up and down, a rubber pad 54 is provided at the clamping end of the first clamping rod 52, and a hexagonal opening is provided at the clamping end of the second clamping rod 53. An edge grinding wheel 55 capable of edge grinding the glass lens 2 is also provided in the housing 51, and a control panel 56 for controlling the entire device is also provided on the side of the lens edge grinder 5.

[0101] Before the glass lens 2 is edged, the first clamping rod 52 and the second clamping rod 53 clamp the glass lens 2 at the same time. The first clamping rod 52 is clamped at the transparent sticker 9 of the glass lens 2 through the rubber pad 54 to prevent the glass lens 2 from being damaged by the clamping. The second clamping rod 53 uses the hexagonal mouth to make the hexagonal block of the suction cup 8 clamp in the hexagonal mouth to achieve positioning. Finally, the glass lens 2 is rotated by the first clamping rod 52 and the second clamping rod 53, and the edge grinding wheel 55 performs edge grinding on it. The operator controls each process through the control panel 56. When the glass processing is completed or an error occurs during the processing, the control panel 56 sends an alarm to remind the staff to operate. The processed glass lens 2 is then placed in the material storage plate 57 through the gripping device 4 for the operator to take.

[0102] Working principle of the present invention:

[0103] Step 1. Before the operator processes the glass lenses 2, first, the operator places a number of unprocessed glass lenses 2 on the lens supporting plate 6. When the glass lenses 2 are placed in the lens supporting opening 13 on the lens supporting plate 6, a reserved opening for grabbing the glass lenses 2 is reserved through the chamfered opening 13 of the lens supporting plate 6, so as to facilitate the clamping of the glass lenses 2 by the clamping mechanism. After all the glass lenses 2 on the lens supporting plate 6 are taken out, the operator can take out the lens supporting plate 6 for loading. When a number of suction cups 8 are placed on the suction cup supporting plate 7, the operator places the number of suction cups 8 in the suction cup placement opening 14 of the suction cup supporting plate 7.

[0104] Step 2, when placing the glass lens 2, the first finger cylinder 17 moves downward through the double-axis double-rod cylinder 23 to grab the glass lens 2, the moving frame 20 drives the first finger cylinder 17 to move horizontally toward the direction of the protective platform 3, and the moving block 21 drives the first finger cylinder 17 to adjust the grabbing direction. The first photoelectric sensor 25 senses the first sensing head 26, which is conducive to the accurate placement of the glass lens 2. The glass lens 2 is then placed in the placement opening 15 on the protective platform 3. After the glass lens 2 is placed in the placement opening 15 of the protective platform 3, the suction cup 8 is attached to the upward side of the glass lens 2, and the transparent sticker 9 is attached to the downward side of the glass lens 2 through the mounting opening 16.

[0105] Step 3: Before attaching the transparent sticker 9, several transparent stickers 9 are attached to a whole patch. The patch is placed in the placement groove 27, and the non-sticking parts of several transparent stickers 9 face downward. Then, the operator manually rotates the screw 30 through the knob 31, and the two pressing plates 29 press the two sides of the patch. When the transparent sticker 9 is removed from the patch, the lower pressing rod 32 drives the pressing head 36 through the pressing port 28 to remove the transparent sticker 9 from the patch. Since the non-sticking part is on the pressing head 36, the transparent sticker 9 is removed from the patch. The sticker 9 will not stick to the pressing head 36. The pressing rod 32 can remove the transparent sticker 9 in all positions through the movement of the first mounting block 34 and the movement of the first push rod 35. When the transparent sticker 9 is removed, the resisting rod 37 presses against the bottom of the sticker through the suction plate 41. After the transparent sticker 9 is pressed down, it is sucked by the suction plate 41, and through the action of the buffer spring 42, when the transparent sticker 9 is pressed down, the suction plate 41 is under pressure to suck the transparent sticker 9 and has a buffering effect downward.

[0106] Step 4, when the transparent sticker 9 is attached to the glass lens 2, the resistance rod 37 moves to the bottom of the mounting opening 16 through the second mounting block 39 and the second push rod 40, and the second photoelectric sensor 43 senses the second sensing head 44, so that the transparent sticker 9 can be accurately mounted on the glass lens 2 through the mounting opening 16. After the protection of the glass lens 2 is completed, the second finger cylinder 47 grabs the glass lens 2 through the two second avoidance openings 50, and the second finger cylinder 47 is rotated 180° by the second rotating motor 49, so that the suction cup 8 on the glass lens 2 faces downward, and the multi-axis manipulator 45 drives the second finger cylinder 47 to move to the lens edger 5, and the first rotating motor 48 adjusts the direction so that the glass lens 2 is accurately located in the appropriate position.

[0107] Step 5. Before the glass lens 2 is edged, the first clamping rod 52 and the second clamping rod 53 clamp the glass lens 2 at the same time. The first clamping rod 52 is clamped at the transparent sticker 9 of the glass lens 2 through the rubber pad 54 to prevent the glass lens 2 from being damaged by the clamping. The second clamping rod 53 uses the hexagonal mouth to make the hexagonal block of the suction cup 8 clamp in the hexagonal mouth to achieve positioning. Finally, the glass lens 2 is rotated by the first clamping rod 52 and the second clamping rod 53, and the edge grinding wheel 55 performs edge grinding on it. The operator controls each process through the control panel 56. When the glass processing is completed or an error occurs during the processing, the control panel 56 sends an alarm to remind the staff to operate. The processed glass lens 2 is then placed in the storage plate 57 through the gripping device 4 for the operator to take.
