Description

Technical Field

[0001] The present application relates to the technical field of optical lens processing equipment, and in particular to an automatic edge grinding device for optical lenses. Background Art

[0002] Optical lenses are made of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. mixed according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasound to remove bubbles, and then slowly cooled for a long time. After cooling, the glass lenses are partially made of round wafers. When processing optical lenses, they need to be polished by edge grinding devices.

[0003] The existing automatic edge grinding device generally uses a conveyor belt to transport the lens, and a processing table for edge grinding is set next to the conveyor frame. A robotic arm cooperates with a suction cup to transfer the lens, thereby forming a loading and unloading mechanism. After the lens is transferred to the processing table, the lens is fixed by the clamping and positioning mechanism matched with the processing table, and then the edge is polished by the polishing mechanism. When polishing a single lens, the loading and unloading mechanism and the fixing mechanism are two separate mechanisms. The switching of the two mechanisms is cumbersome, which makes the efficiency low during batch continuous processing. Therefore, the present application proposes an automatic edge grinding device for optical lenses. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] like Figure 1-Figure 9 As shown, an automatic edge grinding device for optical lenses proposed in one embodiment of the present application includes:

[0031] A transmission frame 1 is provided with a transmission belt 2, and transmission rollers are rotatably provided at both ends of the transmission frame 1. The transmission belt 2 is wound around two transmission rollers, and a driving motor is connected to the end of one of the transmission rollers. The lenses are placed on the transmission belt 2 in a single row, and the driving motor drives the transmission rollers to rotate, so that the transmission belt 2 transmits the lenses;

[0032] The processing table 3 is arranged on one side of the transmission frame 1, and a column 4 is rotatably arranged on the processing table 3, a cross plate 5 is arranged on the top of the column 4, and a first air pipe 7 is rotatably arranged on the end of the cross plate 5 through a lifting member 6, and a first suction cup 8 is connected to the bottom end of the first air pipe 7. A driving part 9 for driving the column 4 to rotate is arranged on the processing table 3. Preferably, the free end of the first air pipe 7 can be connected to an external air pipe through a rotating joint. Under the action of the external air pipe, the lifting member 6 drives the first suction cup 8 to move up and down, so that the first suction cup 8 can adsorb the lens, and the column 4 is driven to rotate by the driving part 9, so that the lens transmitted on the conveyor belt 2 can be transferred to the processing table 3;

[0033] The second air pipe 10 is rotatably arranged on the processing table 3. The top of the second air pipe 10 is connected with a second suction cup 11. When the column 4 rotates, the first suction cup 8 can be coaxially aligned with the second suction cup 11. A driving member 12 for driving the second air pipe 10 to rotate is arranged on the processing table 3. Preferably, the free end of the second air pipe 10 can be connected with an external air pipe through a rotating joint. When the column 4 rotates and the first suction cup 8 is coaxially aligned with the second suction cup 11, the lifting member 6 drives the first suction cup 8 to move downward, so that the adsorbed mirror The lens can be overlapped on the second suction cup 11. At this time, under the action of the external air pipe, the second air pipe 10 can absorb the lens with the second suction cup 11. The first air pipe 7 cooperates with the second air pipe 10 to clamp and fix the lens. The first suction cup 8 and the second suction cup 11 can be used as clamping pads, which can not only firmly clamp the lens but also avoid damage to it. Since the first air pipe 7 and the second air pipe 10 are both rotatably connected, when the driving member 12 drives the second air pipe 10 to rotate, the lens can be driven to rotate;

[0034] The grinding mechanism 13 is arranged on the processing table 3, and is used for grinding the edge of the lens. When the lens is rotating, the outer edge of the lens is ground by the grinding mechanism 13. The overall structure of the device, the first air pipe 7 and the first suction cup 8 can be used as loading and unloading mechanisms for adsorbing and transferring the lens. At the same time, in conjunction with the second air pipe 10 and the second suction cup 11, they can also be used as fixing parts for the lens, so that the upper and lower sides of the lens are clamped and fixed, which not only makes the clamping and fixing effect good, but also the lens can be rotated, and its outer edge can be completely exposed, which is convenient for the grinding mechanism 13 to grind. When a lens is polished, the adsorption of the second suction cup 11 is first released, and then the first suction cup 8 is used to transfer the lens back to the conveyor belt 2, and finally the adsorption of the first suction cup 8 is released, thereby completing the grinding of a single lens. The conveyor belt 2 is transmitting, and the polished lens is transmitted away, and then the next processing lens is transmitted to the position of the first suction cup 8, which is convenient for subsequent processing. The overall structure of the device, the loading and unloading mechanism and the fixing mechanism cooperate with each other, so that the processing efficiency is fast, thereby improving practicality.

[0035] like Figure 7As shown, in some embodiments, the lifting member 6 includes a first cylinder 601 arranged on the horizontal plate 5, the piston end of the first cylinder 601 is connected to the ring plate 602, and the first air pipe 7 is coaxially rotatably arranged on the ring plate 602. Preferably, the number of the first cylinders 601 is two, and the two first cylinders 601 work synchronously, so as to drive the ring plate 602 to rise and fall, thereby achieving the effect of driving the first suction cup 8 to rise and fall. Since the ring plate 602 is rotatably connected to the first air pipe 7, its rotation is not affected while driving it to rise and fall.

[0036] like Figure 8 As shown, in some embodiments, the driving part 9 includes a first gear 901 fixed on the column 4, a second cylinder 902 is arranged on the processing table 3, and the piston end of the second cylinder 902 is provided with a first rack 903 meshing with the teeth of the first gear 901. When the second cylinder 902 does work, its piston end drives the first rack 903 to move, and through the meshing with the teeth of the first gear 901, the column 4 is driven to rotate. The piston end of the second cylinder 902 contracts or extends, thereby driving the cross plate 5 to reciprocate with the column 4 as the center.

[0037] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, a limit rod 14 is provided on the processing table 3 and on both sides of the column 4, a slot 15 is provided on one side of the limit rod 14, an insertion rod 16 is slidably inserted in the slot 15, and a spring 17 is provided between the slot 15 and the insertion rod 16, as shown in FIG. Figure 1 As shown, the two limit rods 14 are used to limit the cross plate 5 to swing back and forth 180 degrees with the column 4 as the center. When the cross plate 5 rotates and overlaps with one of the limit rods 14, the first suction cup 8 is located above the conveyor belt 2, and is used to absorb the lenses on the conveyor belt 2. When the cross plate 5 rotates and overlaps with the other limit rod 14, the first suction cup 8 and the second suction cup 11 are coaxially aligned, so that the two can effectively fix the lenses. Through the set insertion rod 16 and spring 17, when the cross plate 5 rotates and overlaps with the limit rod 14, the cross plate 5 first resists the insertion rod 16, so that the insertion rod 16 slides and shrinks into the slot 15 and squeezes the spring 17, and the elastic force of the spring 17 is used for buffering to prevent the cross plate 5 from hard hitting the limit rod 14, thereby improving practicality.

[0038] like Fig. 9As shown, in some embodiments, the driving member 12 includes a driven gear 1201 fixedly mounted on the second air pipe 10, a first motor 1202 is arranged on the processing table 3, and an output shaft of the first motor 1202 is fixedly provided with a transmission gear 1203 meshing with the teeth of the driven gear 1201. When the first motor 1202 performs work, its output shaft drives the transmission gear 1203 to rotate. By utilizing the meshing of the teeth of the transmission gear 1203 and the driven gear 1201, it is possible to not only drive the second air pipe 10 to rotate, but also does not affect the normal air conduction of the second air pipe 10.

[0039] like Figure 6 As shown, in some embodiments, the grinding mechanism 13 includes a third cylinder 1301 arranged on the processing table 3, and a movable plate 1302 is arranged at the piston end of the third cylinder 1301, and a second motor 1303 is arranged on the movable plate 1302. The output shaft of the second motor 1303 is fixedly provided with a grinding wheel 1304. When the lens is ground, the third cylinder 1301 works first, and its piston end drives the movable plate 1302 to move, thereby driving the grinding wheel 1304 to fit the edge of the lens. The second motor 1303 works, and its output shaft drives the grinding wheel 1304 to rotate, thereby achieving the effect of grinding the edge of the lens. When the lens is ground, the grinding wheel 1304 is first driven away from the lens by the third cylinder 1301, and then the lens is transferred.

[0040] like Figure 2 As shown, in some embodiments, a positioning member 18 is provided on the transmission frame 1, which is used to position the lens coaxially with the first suction cup 8. Since the surface of the lens is relatively smooth, when it is transmitted on the conveyor belt 2, when the conveyor belt 2 stops transmitting, the lens is prone to slight displacement due to the action of inertia. The lens can be positioned by the provided positioning member 18, so that when the first suction cup 8 is located on the conveyor belt 2, it is convenient to quickly and accurately position the lens coaxially with the first suction cup 8, and ensure that when the subsequent lens is fixed, the lens can be coaxial with the first suction cup 8 and the second suction cup 11, which is convenient for subsequent polishing.

[0041] like Figure 3As shown, in some embodiments, the positioning member 18 includes two connecting rods 1801, preferably, the connecting rods 1801 are U-shaped, and the two connecting rods 1801 slide through the two sides of the transmission frame 1 respectively. The two connecting rods 1801 are provided with arc blocks 1802, and a third motor 1803 is provided in the transmission frame 1. The output shaft of the third motor 1803 is fixed with a second gear 1804. The two connecting rods 1801 are provided with second racks 1805, and the two second racks 1805 are meshed with the teeth of the second gear 1804. When the transmission belt 2 transmits the pair of lenses and stops, the third motor 1803 works, and its output shaft belt The second gear 1804 is driven to rotate, and the two connecting rods 1801 can be driven to move in opposite directions synchronously through the meshing of the teeth of the two second racks 1805 and the second gear 1804, thereby driving the two arc blocks 1802 to move in opposite directions synchronously. Due to the arc-shaped structure of the arc blocks 1802, when the two arc blocks 1802 are synchronously close to each other, the lens on the conveyor belt 2 can be quickly positioned so that the lens can be coaxially aligned with the first suction cup 8. Preferably, avoidance grooves are provided on both side panels of the conveyor frame 1, and the two arc blocks 1802 can be moved into the two avoidance grooves respectively, so that the normal movement of the lens is not affected when positioning is not performed.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
