Description

Technical Field

[0001] This invention relates to the field of lens polishing technology, specifically to an optical lens manufacturing apparatus. Background Technology

[0002] In the manufacturing of optical lenses, after initial processing, polishing is required. This is typically done using a lens polishing machine. The machine positions the lens using a negative pressure adsorption structure, and then uses an adjustable rotating polishing head to polish it. The polishing quality directly affects the subsequent light transmission accuracy. Current optical lens manufacturing equipment usually uses a fixed lens positioning structure, which is inconvenient for movement to avoid polishing fluid. After removing the lens, polishing fluid dripping from the polishing head can easily fall directly onto the negative pressure positioning structure, causing contamination. Furthermore, it can damage the lens during subsequent negative pressure positioning. Additionally, traditional negative pressure positioning polishing relies on sealing rings, which lose elasticity over time, affecting sealing quality and making it difficult for workers to check the stability of the negative pressure positioning.

[0003] Therefore, the present invention proposes an optical lens manufacturing apparatus. Summary of the Invention

This prevents workers from directly disassembling the optical lens below the polishing head and polishing fluid filling pipe, which could cause contamination and subsequent wear when the optical lens is subjected to negative pressure. The lens positioning component assists in detecting the stability of the optical lens after it has been positioned by the negative pressure of the support column. Utilizing the transparency of the optical lens itself, it allows workers to quickly check the stability of the optical lens.

[0016] The use of wind-powered protective components, along with a rotatable support column, drives the upper optical lens to rotate. This promotes the removal of polishing fluid adhering to the optical lens, aiding in dehydration. Simultaneously, a blower ring blows air onto the bottom edge of the optical lens, preventing polishing fluid from flowing from the bottom of the optical lens to the negative pressure sealing ring, further keeping the surface of the negative pressure sealing ring clean and reducing the probability of contamination.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 9 As shown: This invention provides a technical solution: an optical lens manufacturing apparatus, including a polishing support 1, a translational sliding part 2 mounted on the polishing support 1, and a lens positioning part 3 mounted on the translational sliding part 2; the lens positioning part 3 is used for negative pressure positioning of the optical lens; a negative pressure control part 4 is mounted on the translational sliding part 2; a position detection part 5 is mounted on the polishing support 1; and a wind protection part 6 is mounted on the translational sliding part 2; the polishing support 1 includes a support plate 101 and mounting holes 1011, with a row of mounting holes 1011 respectively opened on both sides of the bottom of the support plate 101, and the two rows of mounting holes 1011 are used for bolts to pass through and be mounted on a lens polishing machine; a through hole is opened in the middle of the support plate 101.

[0021] The translational sliding part 2 includes: a transverse plate 201, an extrusion inclined groove 2011, a mounting flange 2012, and sliding mounting strips 202. The transverse plate 201 has an extrusion inclined groove 2011 at its bottom, and the inner side of the extrusion inclined groove 2011 is an inclined structure. The mounting flange 2012 is fixedly installed on the transverse plate 201. Two sliding mounting strips 202 are fixedly installed at the bottom of the transverse plate 201, and the two sliding mounting strips 202 are slidably installed on the support plate 101 respectively. The transverse plate 201 is attached to the support plate 101. The translational sliding part 2 also includes: a drive motor 203 and a positioning pin 204. The drive motor 203 is fixedly installed at the bottom of the mounting flange 2012. The drive motor 203 passes through the transverse plate 201. The output shaft of the drive motor 203 passes through the mounting flange 2012; the output shaft of the drive motor 203 is threaded; a positioning pin 204 is slidably inserted into the transverse plate 201, and the end of the positioning pin 204 is inserted into the through hole in the middle of the support plate 101; a tension spring is sleeved on the positioning pin 204, and the tension spring sleeved on the positioning pin 204 is connected between the positioning pin 204 and the transverse plate 201; the lens positioning component 3 includes: a support column 301, a vent hole 3011, a limiting piece 302, and a negative pressure sealing ring 303. The support column 301 is threadedly connected to the output shaft of the drive motor 203; the support column 301 has a vent hole 3011, and the vent hole 3011 has an inverted T-shaped structure; a limiting piece is fixedly installed on the top of the support column 301. A plate 302, and a ring of limiting plates 302 are used to limit the optical lens; two negative pressure sealing rings 303 are fixedly installed on the support column 301, and the two negative pressure sealing rings 303 and the support column 301 are concentrically arranged; the top of the vent 3011 is concentric with the two negative pressure sealing rings 303; the negative pressure sealing rings 303 are used to fit the optical lens to be processed; by using the lens positioning component 3 and the translation sliding part 2, after the optical lens is polished, the position of the support column 301 can be easily moved, avoiding the negative pressure sealing ring 303 at the top of the support column 301 from being contaminated by polishing liquid droplets dripping from the polishing liquid injection pipe and the polishing head, which would affect the sealing performance of the subsequent negative pressure positioning optical lens and cause additional damage; the structure adjustment and control are simple; the lens positioning component 3 also includes: The support column 301 has an annular groove, and the rolling ball 304 is rolled and sleeved in the annular groove of the support column 301. The rolling ball 304 is made of soft rubber. The top of the support column 301 has a scale line. The lens positioning component 3 can be used to assist in the detection of the stability of the optical lens after it is positioned by the negative pressure of the support column 301. The optical lens is transparent, which makes it easy for the staff to quickly check the stability of the optical lens and replace it in time when the negative pressure sealing ring 303 has problems such as aging. After the vacuum pump connected to the negative pressure connecting pipe 402 performs normal vacuum suction positioning, the optical lens is tightly attached to the negative pressure sealing ring 303. At this time, the bottom of the optical lens will also be squeezed and attached to the rolling ball 304.If the negative pressure sealing ring 303 is damaged or severely aged, causing unstable negative pressure adsorption of the optical lens, the optical lens will rotate and loosen due to friction from the polishing head. This will cause the optical lens to rub against the rolling ball 304, resulting in rolling displacement. The negative pressure sealing ring 303 can be checked by manually observing changes in the position of the rolling ball 304.

[0022] The negative pressure control component 4 includes: a negative pressure fixing shell 401 and a negative pressure connecting pipe 402. The negative pressure fixing shell 401 is fixedly installed on the mounting flange 2012. A rubber ring is provided on the inner edge of the negative pressure fixing shell 401. The negative pressure fixing shell 401 is sleeved on the outside of the support column 301. The negative pressure fixing shell 401 connects to the bottom two ends of the vent hole 3011. The negative pressure connecting pipe 402 is fixedly installed on the negative pressure fixing shell 401. The negative pressure connecting pipe 402 is connected to a vacuum pump. The negative pressure control component 4 also includes: a pressure relief solenoid valve 403. The valve pipe of the pressure relief solenoid valve 403 is fixedly installed on the negative pressure fixing shell 401. The position detection component 5 includes: a detection fixing block 501 and a micro switch 502. The detection fixing block 501 is fixedly installed on the support plate 101. The micro switch 502 is fixedly installed on the detection fixing block 501, and the end of the micro switch 502 is... The protruding detection fixing block 501; the micro switch 502 aligns with the extrusion inclined groove 2011; the micro switch 502 is electrically connected to the drive motor 203 and the pressure relief solenoid valve 403. The position detection component 5, in conjunction with the negative pressure control component 4, can detect the position of the transverse plate 201, avoiding direct disassembly of the optical lens by the operator below the polishing head and polishing fluid injection pipe, thus preventing contamination; the structure is simple to control, and the negative pressure fixing shell 401 is sleeved on the outside of the support column 301, which does not affect the normal rotation of the support column 301; when removing the optical lens, the transverse plate 201 needs to be manually slid to move the extrusion inclined groove 2011 to extrude the micro switch 502, ensuring that the optical lens is misaligned from the polishing head and polishing fluid injection pipe. Only then will the micro switch 502 control the drive motor 203 to stop and control the pressure relief solenoid valve 403 to open and release pressure.

[0023] In Example 2, based on Example 1, the wind protection component 6 includes: a support ring 601, a support pipe 602, and a fan connecting pipe 6021. The support ring 601 is fixedly installed on the negative pressure fixing shell 401; the support pipe 602 is fixedly installed on the support ring 601; the fan connecting pipe 6021 is fixedly installed on the support pipe 602; the fan connecting pipe 6021 is connected to a blower via a flexible hose; the wind protection component 6 also includes: a blowing ring 603, which has a hollow cavity structure; the blowing ring 603 is fixedly installed on the support pipe 602; the blowing ring 603 has an annular exhaust groove; the blowing ring 603 connects to the support pipe 602; the blowing ring 603 is used to sweep the bottom edge of the optical lens and can rotate in conjunction with the wind protection component 6. The support column 301 drives the optical lens above to rotate, which can promote the removal of polishing liquid adhering to the optical lens and assist in dehydration. At the same time, the blower ring 603 blows air to the bottom edge of the optical lens to prevent the polishing liquid on the optical lens from flowing from the bottom of the optical lens to the negative pressure sealing ring 303, further keeping the surface of the negative pressure sealing ring 303 clean and reducing the probability of contamination. When the optical lens is rotated for polishing and when it needs to be disassembled after polishing, the polishing liquid on the optical lens will be thrown outward as the support column 301 rotates. With the blower connected to the blower connection pipe 6021, the air force can sweep from the bottom of the optical lens, promoting the polishing liquid to splash outward and not directly contaminating the negative pressure sealing ring 303, making it easy to remove the polishing liquid for disassembly.

[0024] The working principle of this embodiment is as follows: The support plate 101 is installed on the lens polishing machine by bolts. When polishing the optical lens, the optical lens needs to be placed above the negative pressure sealing ring 303. A limiting plate 302 is used to limit the position of the optical lens, keeping the optical lens and the support column 301 concentric, making subsequent polishing more stable. Then, the transverse plate 201 is manually slid to move the support column 301 on the transverse plate 201 to align with the polishing head. At this time, the positioning pin 204 can be manually inserted into the through hole in the middle of the support plate 101 for positioning. When the micro switch 502 is not squeezed, the drive motor 203 can be controlled to rotate, controlling the pressure relief solenoid valve 403 to close. At this time, the vacuum pump connected to the negative pressure connecting pipe 402 maintains normal vacuum suction, ensuring that the optical lens is tightly attached to the negative pressure sealing ring 303. At this time, the bottom of the optical lens will also be squeezed and attached to the rolling ball 304. The polishing head of the lens polishing machine is started to polish the optical lens. Driven by the drive motor 203, the optical lens on the support column 301 can rotate, which helps to promote polishing. If the negative pressure sealing ring 303 is damaged or severely aged, the negative pressure adsorption of the optical lens will be unstable. At this time, the optical lens will be rotated and loosened by the friction of the polishing head. The optical lens will then rub against the rolling ball 304 and roll displacement. When the operator observes the change in the position of the rolling ball 304, the negative pressure sealing ring 303 can be checked. After polishing, if you want to remove the optical lens, you need to manually slide the transverse plate 201 to move the extrusion inclined groove 2011. Use its inclined surface to squeeze the micro switch 502 to ensure that the optical lens is separated from the polishing head and the polishing liquid injection pipe. At this time, the micro switch 502 will control the drive motor 203 to stop and control the pressure relief solenoid valve 403 to open and relieve pressure. Then remove the optical lens, making sure to separate the polishing head and the polishing liquid injection pipe when removing the optical lens to avoid the polishing liquid contaminating the negative pressure sealing ring 303. During the rotational polishing of the optical lens, and when it needs to be disassembled after polishing, the polishing liquid on the optical lens is thrown outward as the support column 301 rotates. With the help of the blower connected to the fan connection pipe 6021, the air force can sweep from the bottom of the optical lens, promoting the polishing liquid to splash outward and not directly contaminating the negative pressure sealing ring 303. This makes it easy to remove the polishing liquid for disassembly. The lens polishing machine itself is installed in a groove structure, so the splashed droplets will be collected directly.
