Description

Technical Field

[0001] The present invention relates to the technical field of optical lenses, and in particular to a bubble elimination device for manufacturing optical lenses. Background Art

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melting it at high temperature in a platinum crucible, stirring it evenly with ultrasound to remove bubbles; then it is cooled slowly over a long period of time to prevent internal stress in the glass block. After the cooled glass block is measured by optical instruments, the qualified glass block is heated and forged to become an optical lens blank.

[0003] When producing and processing optical lenses, air will inevitably enter the adhesive during the stirring process, causing bubbles to appear in the adhesive. At the same time, the bubbles cannot be automatically and completely removed under natural conditions. After the optical lens with bubbles is formed, the bubbles will affect the shooting and video recording of the camera using the optical lens, causing the projected part of the photographed object to be enlarged or reduced, resulting in different sizes of the photographed objects, affecting the imaging effect and viewing experience.

[0004] To solve the above problems, the inventors proposed a bubble elimination device for optical lens manufacturing, which has the advantage of isolating the air while pressing and extracting bubbles. Summary of the Invention

[0005] In order to achieve the above-mentioned purpose of isolating the air while pressing and extracting the bubbles, the present invention provides the following technical solutions:

[0008] Furthermore, the rotating assembly includes a sealed groove, which is fixedly connected to the upper surface of the shell by bolts. The interior of the sealed groove is rotatably connected to the rotating groove, and the surface of the rotating groove is equidistantly provided with drainage holes.

[0009] Furthermore, the pressing assembly includes a push handle, a spring retraction rod is provided on the lower surface of the push handle, and a resistance block is rotatably connected to the lower surface of the spring retraction rod. The right side of the push handle is fixedly connected to a moving rod by a bolt, and a first spring is sleeved on the outer wall surface of the moving rod. The top of the first spring is welded to the top of the moving rod, and the bottom of the first spring is welded to the bottom of the inner cavity of the shell. The bottom end of the moving rod slides inside the first limiting hole, and a gear rod is welded on the front side of the first spring. A second guide hole is opened in the middle of the gear rod, and the gear rod slides inside the third limiting hole.

[0010] Furthermore, the gear assembly includes a first fixed rod, the end of the first fixed rod away from the closed groove is rotatably connected to the inner surface of the shell, the surface of the first fixed rod is welded with a gear shaft, the gear shaft and the side bottom of the gear rod are meshed with each other, the end of the first fixed rod away from the gear shaft is welded with a first gear, the bottom of the inner cavity of the shell is rotatably connected to a second fixed rod, the outer wall of the second fixed rod is welded with a second gear, and the first gear and the second gear are meshed with each other, the top end of the second fixed rod is rotatably connected to the bottom of the closed groove, and the top end of the second fixed rod is welded to the bottom of the rotating groove.

[0011] Furthermore, the drainage assembly includes a drainage chamber, which is opened through the bottom of the closed groove, and the interior of the drainage chamber is slidably connected to a piston rod, the outer wall of the piston rod is sleeved with a second spring, the bottom end of the second spring is welded to the interior of the drainage chamber, and the top of the second spring is welded to the top of the piston rod, the interior of the first guide hole is fixedly connected to a drainage pipe, the bottom end of the piston rod is abutted and connected to the inner wall of the drainage pipe, and a water inlet hole is opened at one end of the drainage pipe close to the piston rod.

[0012] Furthermore, the top size of the piston rod is larger than the inner diameter of the drainage cavity, and the top of the piston rod blocks the drainage cavity.

[0014] Beneficial effects

[0015] Compared with existing technologies and products, the present invention has the following beneficial effects:

[0016] 1. By pressurizing the optical lens, not only the air in the closed groove is reduced, but also the bubbles inside the optical lens are moved to the edge of the adhesive by squeezing the optical lens through the resistance block. Then, the bubbles burst because the air pressure inside the bubbles is greater than the air pressure inside the closed groove, thereby effectively removing the bubbles inside the optical lens. This avoids the problem that the imaging effect is affected by the presence of too many bubbles inside the optical lens when people use the optical lens for shooting, and also improves the production efficiency of the optical lens.

[0017] 2. The rotating groove drives the optical lens to rotate while the optical lens is squeezed by the resistance block, thus avoiding the problem that when squeezing the adhesive placed between the two optical lenses, the bubbles in the adhesive cannot be completely moved to the edge of the adhesive through squeezing, and a small amount of bubbles still remain in the optical lens. When the optical lens rotates at high speed, the bubbles are made to move centrifugally inside the adhesive, so that the bubbles are separated from the adhesive and then from the optical lens for removal, which is beneficial for the optical lens to keep the imaging ratio of each part of the object consistent when shooting;

[0018] 3. The adhesive inside the closed tank will flow into the water inlet through the drainage cavity and be discharged to the outside of the equipment through the drainage pipe for collection, thus preventing the adhesive inside the closed tank from gradually increasing and entering the interior of the rotating tank through the drainage hole and contacting the optical lens again, thereby preventing the secondary generation of bubbles inside the optical lens.

The drainage pipe 504 is provided with a water inlet hole 505 at one end close to the piston rod 503.

[0044] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0045] When in use, the operator first places the two semi-finished optical lenses with adhesive into the interior of the rotating groove 202, and then manually presses the button 301, so that the button 301 drives the resistance block 303 to move into the closed groove 201 through the spring contraction rod 302, and continues to move into the interior of the rotating groove 202 inside the closed groove 201. When the resistance block 303 resists the optical lens and continues to move downward, it squeezes the optical lens, thereby pressurizing the optical lens and squeezing out excess bubbles in the optical lens, which not only reduces the air in the closed groove 201, but also squeezes the optical lens through the resistance block 303 so that the bubbles inside the optical lens move to the edge of the adhesive, and then the air pressure inside the bubble is greater than the air pressure inside the closed groove 201, causing the bubble to burst, thereby achieving the effect of clearing the bubbles inside the optical lens, avoiding the problem that when people use the optical lens to take pictures, the imaging effect is affected by too many bubbles inside the optical lens, and the production quality of the optical lens is also improved.

[0046] When the lever 301 is pressed downward, the movable rod 304 is moved downward synchronously and the first spring 305 is pressed. At this time, the movable rod 304 drives the gear rod 306 to slide vertically downward inside the third limiting hole 106, so that the gear rod 306 drives the drain pipe 504 downward through the second guide hole 307 opened on the surface. At this time, the inner cavity of the water inlet hole 505 opened on the side of the closed groove 201 of the drain pipe 504 no longer conflicts with the lower end of the piston rod 503. At this time, the piston rod 503 is driven to slide downward inside the drainage chamber 501 under the elastic expansion and contraction action of the second spring 502, so that the top of the piston rod 503 blocks the top of the drainage chamber 501. At the same time, the gear rod 306 drives the gear shaft 402 meshing with it to rotate clockwise while always sliding on the surface of the gear rod 306, so that the gear shaft 402 drives the first fixed rod 401 to rotate inside the housing 101. The wheels 403 rotate synchronously. At this time, the first gear 403 will drive the second gear 405 meshing with it to rotate synchronously in the clockwise direction, so that the second gear 405 drives the second fixing rod 404, so that the lower surface of the second fixing rod 404 rotates clockwise at the bottom of the inner cavity of the shell 101, and then the upper surface of the second fixing rod 404 drives the rotating groove 202 to rotate inside the closed groove 201, so that the optical lens is squeezed by the resistance block 303 while being driven to rotate by the rotating groove 202, avoiding the problem that the bubbles in the adhesive cannot be completely moved to the edge of the adhesive through squeezing when squeezing the adhesive placed between the two optical lenses, and thus a small amount of bubbles still remain in the optical lens, so that the bubbles are made to perform centrifugal motion inside the adhesive when the optical lens rotates at high speed, so that the bubbles are separated from the adhesive and then separated from the optical lens for removal, which is beneficial to keep the imaging ratio of each part of the object consistent when the optical lens is shooting.

[0047] When the lower surface of the resistance block 303 is in contact with the optical lens and squeezes the optical lens appropriately, the person no longer continues to press the button 301. At the same time, the button 301 cannot drive the resistance block 303 to move downward by driving the spring contraction rod 302. At the same time, the button 301 cannot drive the gear rod 306 to move downward by driving the moving rod 304, so that the gear rod 306 cannot drive the gear shaft 402 meshing with it to drive the first fixed rod 401 to rotate. At the same time, the first fixed rod 401 cannot drive the second gear 405 to rotate by driving the first gear 403, so that the second gear 405 cannot drive the rotating groove 202 to rotate inside the closed groove 201 by driving the second fixed rod 404. At this time, the closed groove 201 stops rotating.

[0048] When the operator no longer presses the button 301, the elastic extension of the first spring 305 drives the moving rod 304 to move upward. At this time, the moving rod 304 drives the second guide hole 307 to move upward through the gear rod 306, so that the second guide hole 307 drives the drain pipe 504 to move upward. When the end of the drain pipe 504 close to the sealed groove 201 moves to the bottom of the sealed groove 201, and the drainage cavity 501 contacts the inner cavity of the water inlet hole 505 opened on the side of the drain pipe 504 close to the sealed groove 201, the drain pipe 504 continues to move upward, causing the water inlet hole 505 to hit the bottom end of the piston rod 503, causing the piston rod 503 to The second spring 502 slides upward inside the drainage chamber 501 and stretches the top of the piston rod 503. At this time, the top of the piston rod 503 no longer blocks the top of the drainage chamber 501. The excess adhesive and water squeezed out of the closed groove 201 will flow into the water inlet hole 505 through the drainage chamber 501 and be discharged to the outside of the device through the drain pipe 504 for collection, thereby preventing the adhesive inside the closed groove 201 from gradually increasing and entering the rotating groove 202 through the drainage hole 203 and contacting the optical lens again, thereby preventing the secondary generation of bubbles inside the optical lens. When the first spring 305 returns to its initial state, the device stops working.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
