Description

Technical Field

[0001] The present utility model relates to the technical field of optical lens processing, and particularly relates to an adjustable gluing device for optical lenses. Background Art

[0002] Gluing refers to adhesively bonding two or more optical lenses together according to actual requirements through special glue to produce finished optical lenses with different effects. The quality of the gluing of optical lenses affects the imaging quality of the optical lenses. Therefore, gluing is very important in the process of optical lens processing.

[0003] A patent with the patent publication number CN212883302U discloses a gluing device for optical lens processing, including a bottom plate. One side of the upper surface of the bottom plate is fixedly installed with a motor, the output shaft end of the motor is fixedly connected with a rotating shaft, one end of the rotating shaft is fixedly connected with a gear, one side of the upper surface of the bottom plate is provided with a turntable, the bottom of the turntable is fixedly installed with a universal ball, the universal ball is rotatably installed on the bottom plate, and a toothed ring is fixedly sleeved on the outer wall of the turntable.

[0004] When using the above gluing device, the lens is clamped and fixed by a slider and a spring, and then the motor is started, so that the rotating shaft drives the gear to rotate, thereby driving the toothed ring to rotate, making the universal ball rotate. Then the air pump is started, so that the glue is dripped onto the lens through a glue dripping head for gluing. After long-term use, the elasticity of the spring will decrease, resulting in a decrease in the fixing effect on the lens, so that the lens may shift during the glue dripping process.

Specific Embodiments

[0050] First of all, it should be pointed out that in different described embodiments, the same components are provided with the same reference numerals or the same component names. Among them, the disclosed content included in the entire specification can be meaningfully applied to the same components with the same reference numerals or the same component names. The positional descriptions selected in the specification, such as up, down, lateral, etc., also refer to the directly described and shown drawings and are meaningfully applied to the new positions when the positions change.

[0051] Example 1: An adjustable gluing device for optical lenses, as Figure 1 and Figure 2As shown in the figure, it includes a support frame 1, a pressing frame 2, a coaxial mechanism 3, and a pressure mechanism 4. The upper part of the support frame 1 is slidably connected with the pressing frame 2. A coaxial mechanism 3 for making the lenses completely overlap is provided on the support frame 1. The coaxial mechanism 3 is used to align the axes of the two lenses, that is, to make the two lenses completely overlap. The upper part of the pressing frame 2 is provided with a pressure mechanism 4 for evenly pressing the lenses, so that the glue more evenly fills the gap between the two lenses.

[0052] As Figure 1 and Figure 3 shown in the figure, the coaxial mechanism 3 includes a synchronous disk 31, positioning rods 32, and a pushing block 33. The lower part of the support frame 1 is rotatably connected with the synchronous disk 31. Three arc-shaped tracks are evenly opened on the synchronous disk 31 along the circumferential direction. Three positioning rods 32 are evenly slidably connected to the lower part of the support frame 1 along the circumferential direction. The positioning rods 32 are respectively slidably connected with the adjacent arc-shaped tracks. The front side of the synchronous disk 31 is fixedly connected with the pushing block 33. By rotating the pushing block 33 to drive the synchronous disk 31 to rotate, the positioning rods 32 are squeezed, so that the positioning rods 32 move towards the center of the support frame 1 and squeeze the lenses, so as to finely adjust the positions of the lenses, so that the two lenses completely overlap.

[0053] As Figure 1 , Figure 4 and Figure 5 shown in the figure, the pressure mechanism 4 includes an L-shaped pipe 41, an adjusting screw 42, and a first piston 43. The upper side of the support frame 1 is fixedly connected with the L-shaped pipe 41. The L-shaped pipe 41 is slidably connected with the pressing frame 2. The right side of the upper part of the L-shaped pipe 41 is threadedly connected with the adjusting screw 42. A turning handle is provided on the right side of the adjusting screw 42. The left side of the adjusting screw 42 is rotatably connected with the first piston 43. The first piston 43 is slidably connected with the L-shaped pipe 41. By rotating the adjusting screw 42 and making the first piston 43 squeeze the air in the L-shaped pipe 41 to the left, the air is used to squeeze the pressing frame 2 downward.

[0054] When using the adjustable gluing device for optical lenses, first place the first lens in the middle of the lower part of the support frame 1, that is, the three positioning rods 32 surround the outer ring of the first lens, then drip glue on the first lens, and then place the second lens on top of the first lens. Since the glue is still in liquid at this time, the two lenses can still move. At this time, people can rotate the push block 33 to drive the synchronous disk 31, and the arc track on the synchronous disk 31 will squeeze the positioning rods 32, so that the three positioning rods 32 move toward the center of the support frame 1, and at the same time, the two lenses are slightly squeezed to fine-tune the positions of the two lenses so that the two lenses can be moved. The axes of the two lenses are aligned, which means that the two lenses can be completely overlapped, so that the lenses can be more perfectly fitted together, and the gluing quality of the lenses is better. Subsequently, the turning handle provides a fulcrum for people to turn the adjusting screw 42, and the adjusting screw 42 moves to the left, driving the first piston 43 to move to the left, and the first piston 43 squeezes the air in the L-shaped tube 41, so that the air in the L-shaped tube 41 squeezes the pressing frame 2 downward, so that the pressing frame 2 can replace the human hand to evenly apply pressure to the lenses, so that the glue is more evenly distributed in the gap between the two lenses, avoiding the situation that the corresponding position is caused by excessive force on one side. In the case of less glue, evenly applying pressure can make the glue more even, thereby further making the lenses fit together perfectly and making the gluing quality better. In addition, people can control the speed of rotating the adjusting screw 42, thereby controlling the downward squeezing force of the pressing frame 2, and preventing the lenses from being damaged due to excessive squeezing force. After the glue is solidified, when people need to take out the glued lenses, they can rotate the pushing block 33 in the opposite direction to drive the synchronous disk 31 to rotate in the opposite direction, thereby moving the three positioning rods 32 away from the center position of the supporting frame 1 to reset, and then rotate the handle in the opposite direction to drive the adjusting screw 42 to rotate in the opposite direction, and move the adjusting screw 42 to the right to reset, bringing The first piston 43 is moved to the right and reset, thereby causing the pressing frame 2 to move upward and reset. At this time, people can take away the glued lenses. In summary, people can drive the synchronous disk 31 to rotate by rotating the pushing block 33, so that the arc track on the synchronous disk 31 squeezes the positioning rod 32, thereby causing the positioning rod 32 to move toward the center of the support frame 1, thereby slightly squeezing the lenses so that the two lenses can completely overlap. By rotating the adjusting screw 42, the adjusting screw 42 drives the first piston 43 to move to the left, thereby causing the pressing frame 2 to move downward to apply uniform pressure to the lenses, so that the lenses fit more perfectly and the gluing quality of the lenses is better.

[0055] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 6 and Figure 7As shown, it further includes an adaptation mechanism 5. The adaptation mechanism 5 includes an axle center frame 51 and rubber blocks 52. Six axle center frames 51 are fixedly connected to the lower part of the support frame 1 along the circumferential direction. Rubber blocks 52 are rotatably connected to both sides of the axle center frame 51. The rubber blocks 52 can deform appropriately, so as to better adapt to lenses with different arc surfaces.

[0056] When the first lens is placed on the support frame 1, at this time the first lens will be above the rubber blocks 52, and the rubber blocks 52 can slightly lift the first lens upward. When the pressing frame 2 presses the second lens downward, it will cause the first lens to squeeze the rubber blocks 52. Since the arc surfaces of different lenses are different, the rubber blocks 52 can rotate and tilt accordingly according to the arc surface of the lens, and the rubber blocks 52 can also deform appropriately to adapt to lenses with different arc surfaces, so as to better support the lens and keep the lens parallel to the ground, avoiding the situation of lens skew. In this way, the gluing quality of lenses with different arc surfaces can be better.

[0057] As Figure 1 、 Figure 8 and Figure 9 shown, it further includes an adsorption mechanism 6. The adsorption mechanism 6 includes a suction cup 61, a second piston 62, a connecting frame 63 and a spring 64. The second piston 62 is slidably connected to the middle position of the inner lower part of the support frame 1. The suction cup 61 is fixedly connected to the upper part of the second piston 62. The suction cup 61 is communicated with the second piston 62. The connecting frame 63 is slidably connected to the lower side of the support frame 1. The upper side of the left part of the connecting frame 63 is in pressing cooperation with the pressing frame 2. The lower right side of the connecting frame 63 is fixedly connected to the second piston 62. A spring 64 is wound between the connecting frame 63 and the lower part of the support frame 1. The upper part of the spring 64 is connected to the lower part of the support frame 1, and the lower part of the spring 64 is connected to the connecting frame 63. By moving the pressing frame 2 downward and no longer pressing the connecting frame 63, the connecting frame 63 drives the second piston 62 to move downward, so that the first lens can be adsorbed by the suction cup 61.

[0058] In the initial state, the pressing frame 2 is located above and presses the connecting frame 63, causing the connecting frame 63 to also be located above. The spring 64 is in a compressed state. When the pressing frame 2 moves downward to press the lens, the pressing frame 2 no longer presses the connecting frame 63. The connecting frame 63 will then move downward under the action of the spring 64, driving the second piston 62 to move downward, making the space between the second piston 62 and the suction cup 61 larger. Since the total amount of air remains unchanged, negative pressure will be generated. Since the first lens is placed on the suction cup 61, that is, the first lens can completely cover the suction cup 61, the suction cup 61 can adsorb the first lens, and cooperate with the three positioning rods 32 to surround the outer circle of the two lenses, thereby limiting and fixing the lenses, preventing the lenses from shifting when pressed by the pressing frame 2, and thus making the gluing effect of the lenses better. When the gluing of the lenses is completed, the pressing frame 2 moves upward to reset. The pressing frame 2 will then press the connecting frame 63 again, causing the connecting frame 63 to move upward to reset. The spring 64 is compressed and reset. The connecting frame 63 will also drive the second piston 62 to move upward and push the air upward, so that the suction cup 61 releases the adsorption of the first lens.

[0059] As Figure 1 and Figure 10 shown, it further includes a curing mechanism 7. The curing mechanism 7 includes a sliding sleeve 71 and a UV lamp 72. The front and rear sides of the left part of the support frame 1 are both slidably connected with sliding sleeves 71, and UV lamps 72 are fixedly connected to the sliding sleeves 71. The lenses are irradiated by the UV lamps 72 to accelerate the curing speed of the glue.

[0060] In order to accelerate the curing speed of the glue, people generally use an ultraviolet lamp to irradiate the lenses with ultraviolet rays. However, during this process, the lenses need to be picked up for irradiation. Since the glue may not be completely cured at this time, moving the lenses may cause displacement between the two lenses, which will also affect the gluing quality of the lenses and even cause defects in the final lens products. Therefore, when using this adjustable gluing device for optical lenses to irradiate the lenses with ultraviolet rays, people can turn on the UV lamp 72 and directly irradiate the lenses with ultraviolet rays through the UV lamp 72. And people can also move the sliding sleeve 71 up and down to drive the UV lamp 72 to move up and down, so as to irradiate the lenses more comprehensively with ultraviolet rays. In this way, by moving the UV lamp 72 instead of moving the lenses, while accelerating the curing speed of the glue, it can also avoid the displacement of the lenses caused by moving the lenses, thereby making the gluing quality better. When the glue is completely cured, turn off the UV lamp 72.

[0061] As Figure 1 and Figure 11As shown, it further includes a dust display mechanism 8 for detecting whether dust or impurities adhere to the lens. The dust display mechanism 8 includes a connecting arm 81 and a dust display lamp 82. The right side of the upper part of the support frame 1 is fixedly connected with the connecting arm 81, and the right side of the connecting arm 81 is rotatably connected with the dust display lamp 82. By irradiating the lens with the dust display lamp 82, it is convenient for people to check whether there is dust or impurities on the lens through the dust display lamp 82.

[0062] The presence of dust or impurities on the lens may also affect the gluing quality of the lens and even the imaging quality of the final lens product. Therefore, people can turn on the dust display lamp 82 before dripping glue on the lens and irradiate the lens with the dust display lamp 82. At the same time, people can also rotate the dust display lamp 82 to make the dust display lamp 82 irradiate the lens more comprehensively, which is more convenient for people to check whether there is dust or impurities adhering to the lens. If so, it needs to be wiped clean in time. In this way, it can be ensured that the lens is in a clean state for gluing operation, and the gluing quality of the lens can also be better. After checking the lens, just turn off the dust display lamp 82.

[0063] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
