Description

Technical Field

[0001] The invention relates to the technical field of optical glass processing, and more specifically to an optical glass precision milling and grinding device. Background Art

[0002] In the field of optical device manufacturing, optical glass is an important basic material, and its surface quality directly affects the performance of the optical system. In particular, tubular optical glass has extremely high requirements for the finish and flatness of the inner wall due to its unique shape and wide range of applications (such as fiber optic communications, laser technology, medical equipment, etc.). However, in the manufacturing process of optical glass, due to the influence of material properties, processing technology and environmental factors, tiny burrs or protrusions often appear on its inner wall. These defects will not only reduce the optical performance, but may also cause light scattering, energy loss or even damage to the optical system during use.

[0003] Traditional methods of grinding the inner wall of optical glass have many shortcomings. On the one hand, although manual grinding can remove burrs to a certain extent, it is inefficient and requires high skills from the operator, making it difficult to ensure the consistency and accuracy of grinding. On the other hand, although automated grinding equipment has improved production efficiency, it often lacks the ability to accurately detect and locate the location of burrs, resulting in unnecessary damage to non-target areas during the grinding process, which not only increases costs but may also affect the overall performance of the optical glass.

[0004] Especially for tubular optical glass products, defects such as burrs or protrusions inside are difficult to be discovered and located. Due to its own light transmittance, it is difficult to effectively locate tiny burrs and then grind them specifically. The existing technology generally performs overall grinding, but it is easy to cause wear on regular areas, which will reduce the quality.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an optical glass precision milling and grinding device. Summary of the invention

[0031] An implementation of the present application is described in detail below with reference to the accompanying drawings.

[0032] Example:

[0033] See also Figure 1, an optical glass fine milling and grinding device, comprising a transmission platform 1, a positioning component 2, a driving component 3, a monitoring grinding component 4 and a monitoring tube 5, the transmission platform 1 is provided with a plurality of evenly distributed positioning components 2, and a pair of mutually symmetrical annular blocks 22 are installed on both sides of the transmission platform 1; the positioning component 2 comprises a transmission seat 21, both ends of the transmission seat 21 are provided with sealing extrusion rods 23, and the bottom end of the transmission seat 21 is fixedly connected to the transmission chain on the transmission platform 1, and the sealing extrusion rod 23 is slidably connected to the annular block 22; the driving component 3 is arranged on the upper side of the transmission platform 1, the driving component 3 comprises a pair of brackets 31, a pair of brackets 31 are fixedly connected with a connecting plate 32 close to one end, and a hydraulic rod 33 is installed at the top of the connecting plate 32; the monitoring grinding component 4 comprises a driving plate 41, the top of the driving plate 41 is fixedly connected to the output end of the hydraulic rod 33, and a plurality of evenly distributed monitoring tubes 5 and intelligent grinding heads 42 are installed at the bottom end of the driving plate 41; the monitoring tube 5 is composed of a bottom plate component 6 and a monitoring tube component 7.

[0034] The intelligent grinding head 42 is equipped with a high-precision servo motor and sensor, which is the existing technology. Its structure and principle will not be repeated here. It can realize real-time monitoring and feedback adjustment of the grinding process. During the grinding process, the intelligent grinding head will automatically adjust the grinding path and grinding depth according to the preset grinding parameters and real-time feedback data to ensure that it only acts on the burr area to avoid damage to non-target areas.

[0035] Among them, this scheme combines the precise positioning of the hydraulic rod 33, the fusion bonding of the heating rod 67 and the proximity capsule 71, the color feedback of the electrochromic material and the pressure sensing technology of the piezoelectric film, so as to realize the automatic detection and removal of the burr protrusions on the inner wall of the tubular optical glass. Through the coordinated control of the hydraulic rod 33 and the electromagnet 62, the multiple base plate components 6 and the monitoring tube component 7 of the monitoring grinding component 4 are accurately delivered into the interior of the tubular optical glass 25; the heating rod 67 preheats the proximity liquid 72 in the proximity capsule 71 to melt it and solidify it at the burr protrusion to form a raised mark; the piezoelectric film generates a voltage when sensing the burr pressure, driving the electrochromic material to change color, which is captured by the color capture camera 68 and analyzed for data, and finally the intelligent grinding head 42 performs precise grinding according to the data. This not only improves the grinding efficiency and reduces damage to non-target areas, but also enables the reuse of tubular optical glass through the reversible properties of the material. The entire device ensures that the grinding process only acts on the burr area through a feedback mechanism to avoid damaging other parts of the tubular optical glass. In addition, the proximity liquid 72 uses a thermoreversible resin material, which softens or melts when heated and re-hardens after cooling. The reversible property of this material allows it to be reused in future grinding cycles, increasing the economy and environmental protection of the system. Through this highly automated and precise method, not only the accuracy of the inner wall grinding of the tubular optical glass is improved, but also the production efficiency is significantly improved.

[0036] See also Figure 2 A pair of mutually symmetrical extrusion grooves 26 are provided on the transmission seat 21, and the extrusion grooves 26 are slidably connected to the sealing extrusion rod 23. A plurality of evenly distributed elastic strips 27 are fixedly connected to the inner wall of the extrusion groove 26, and one end of each of the plurality of elastic strips 27 is fixedly connected to one end of the sealing extrusion rod 23. A plurality of evenly distributed placement grooves 24 are provided on the top of the transmission seat 21, and a tubular optical glass 25 is installed in the placement groove 24. A positioning capsule 28 is installed on the inner wall of the placement groove 24, and the positioning capsule 28 is abutted against the outer surrounding of the tubular optical glass 25. The plurality of positioning capsules 28 are connected to each other. An extrusion groove 26 is provided in the transmission seat 21, and the extrusion groove 26 is connected to the positioning capsule 28. The depth change corresponding to the groove provided on the annular block 22 is first reduced and then expanded.

[0037] When the tubular optical glass 25 is clamped, the plurality of tubular optical glasses 25 are clamped by a feeder and placed in the plurality of placement grooves 24 provided in the transmission seat 21. The feeder belongs to the prior art and will not be described in detail here. When the transmission platform 1 is started, the plurality of transmission seats 21 are synchronously driven to move in the transmission platform 1. A pair of mutually symmetrical sealing extrusion rods 23 are provided in the transmission seat 21, and the depth change corresponding to the groove provided on the annular block 22 is first reduced and then expanded, so that when the sealing extrusion rod 23 slides in the groove provided in the annular block 22, the sealing extrusion rod 23 is squeezed by the groove. The elastic strip 27 is pressed into the transmission seat 21, so that the sealing extrusion rod 23 squeezes the elastic strip 27 and squeezes the gas in the extrusion groove 26 into the positioning capsule 28, so that the positioning capsule 28 expands and completes the fixation of the tubular optical glass 25. After the subsequent grinding is completed, the transmission table 1 is started and the groove depth changes, so that the elastic strip 27 squeezes the sealing extrusion rod 23, so that the gas in the positioning capsule 28 enters the extrusion groove 26 again, thereby releasing the fixation of the tubular optical glass 25, and the tubular optical glass 25 falls into the collection box under the action of gravity, and is cyclically ground in this way.

[0038] See also Figure 3-9 The bottom plate assembly 6 includes a monitoring bottom plate 61, an electromagnet 62 is installed on the outer surface of the monitoring bottom plate 61, and a plurality of evenly distributed slide grooves 63 are opened on the monitoring bottom plate 61, a telescopic rod 64 is fixedly connected to the inner wall of the slide groove 63, a slider 66 is fixedly connected to one end of the telescopic rod 64, a telescopic spring 65 is arranged outside the telescopic rod 64, and the two ends of the telescopic spring 65 are respectively fixedly connected to the inner wall of the slide groove 63 and the slider 66, a heating rod 67 is fixedly connected to the top of the slider 66, a monitoring tube assembly 7 is arranged outside the plurality of heating rods 67, and a plurality of evenly distributed heat-conducting wires are installed near one end of the plurality of heating rods 67, and the monitoring tube assembly 7 includes a close capsule 71, and the outer shell of the plurality of heating rods 67 is connected to the inner wall of the close capsule 71.

[0039] The proximity capsule 71 is filled with proximity liquid 72, and the material of the proximity liquid 72 is set to be a thermoreversible resin material. A sealing cover 73 is installed on the top of the proximity capsule 71, and a feedback capsule is installed in the proximity capsule 71. A color capture camera 68 is fixedly connected to the top of the electromagnet 62. The feedback capsule is filled with feedback liquid, and a piezoelectric film is installed in the feedback capsule and on one side close to the inner surrounding of the proximity capsule 71. The material of the feedback liquid is set to be an electrochromic material.

[0040] Among them, when the inner wall of the tubular optical glass 25 is first detected and positioned, when the first transmission seat 21 moves to the lower side of the monitoring grinding assembly 4, the power switch of the hydraulic rod 33 is started, so that the output end of the hydraulic rod 33 drives the monitoring grinding assembly 4 to move downward, thereby synchronously driving multiple bottom plate assemblies 6 and monitoring tube assemblies 7 to enter the tubular optical glass 25. At this time, the power switch of the electromagnet 62 is started, so that the electromagnet 62 generates a repulsive force on the multiple sliders 66, so that the sliders 66 synchronously drive the heating rod 67 to move away from the electromagnet 62, thereby synchronously driving the heating rod 67 and the close capsule 71 to move and adhere to the inner wall of the tubular optical glass 25.

[0041] Before the base plate assembly 6 and the monitoring tube assembly 7 enter the tubular optical glass 25, the multiple heating rods 67 are in the activated state, and multiple uniformly distributed heat-conducting wires are installed at one end of the multiple heating rods 67 close to each other, so that the proximity liquid 72 filled in the proximity capsule 71 is in a molten state. When the electromagnet 62 is activated to drive the heating rods 67 and the proximity capsule 71 to move and attach to the inner wall of the tubular optical glass 25, the heating rods 67 are turned off, so that the proximity capsule 71 is solidified when it contacts the inner wall of the tubular optical glass 25. When there are burrs and protrusions on the inner wall of the tubular optical glass 25, the proximity capsule 71 will be squeezed, so that the inner wall of the proximity capsule 71 is in a convex state.

[0042] A feedback capsule is installed in the inner enclosure of the monitoring tube assembly 7, and the material of the feedback liquid filled in the feedback capsule is set to be an electrochromic material. At the same time, a piezoelectric film is installed in the feedback capsule and close to the inner enclosure of the monitoring tube assembly 7. The electrochromic material is a material that can change its color under the action of applied voltage. This color change is due to the reversible redox reaction of electrons or ions in the material under the action of the electric field, and the color change of the electrochromic material is reversible and can be reused.

[0043] The piezoelectric film is a thin film material that can generate voltage when subjected to mechanical pressure, or will produce mechanical deformation when voltage is applied, which is called the piezoelectric effect. When there are burrs on the inner wall of the tubular optical glass 25, the piezoelectric film can be squeezed to generate a certain voltage, which can act on the feedback liquid in the feedback capsule, causing it to change color, and finally be captured by the color capture camera 68, completing the positioning of the burrs on the inner wall of the tubular optical glass 25, and using the positioning algorithm to transmit its data to the multiple corresponding intelligent grinding heads 42 installed on the drive board 41. When the tubular optical glass 25 is subsequently ground, the inner wall of the tubular optical glass 25 can be accurately ground based on the transmitted data, which not only improves its grinding efficiency, but also avoids grinding of unnecessary areas.

[0044] In subsequent use, detection and grinding can be carried out simultaneously. At the same time, the material of the proximity liquid 72 is set to a thermoreversible resin material, which can soften or melt when heated to a certain temperature and re-harden after cooling. This transformation is reversible, that is, the resin can be heated and cooled repeatedly without significantly degrading its performance, so it can be reused.

[0045] Working principle:

[0046] When the tubular optical glass 25 is clamped, the plurality of tubular optical glasses 25 are clamped by a feeder and placed in the plurality of placement grooves 24 provided in the transmission seat 21. The feeder belongs to the prior art and will not be described in detail here. When the transmission platform 1 is started, the plurality of transmission seats 21 are synchronously driven to move in the transmission platform 1. A pair of mutually symmetrical sealing extrusion rods 23 are provided in the transmission seat 21, and the corresponding depth change of the groove provided on the annular block 22 is first reduced and then expanded, so that when the sealing extrusion rod 23 slides in the groove provided in the annular block 22, the sealing extrusion rod 23 is squeezed into the groove. The sealing extrusion rod 23 is inserted into the transmission seat 21, so that the sealing extrusion rod 23 squeezes the elastic strip 27 and squeezes the gas in the extrusion groove 26 into the positioning capsule 28, so that the positioning capsule 28 expands to fix the tubular optical glass 25. After the subsequent grinding is completed, the transmission table 1 is started and the groove depth changes, so that the elastic strip 27 squeezes the sealing extrusion rod 23, so that the gas in the positioning capsule 28 enters the extrusion groove 26 again, thereby releasing the fixation of the tubular optical glass 25. The tubular optical glass 25 falls into the collection box under the action of gravity, and the grinding is cyclically carried out in this way;

[0047] The monitoring grinding assembly 4 is precisely positioned above the tubular optical glass 25 by the hydraulic rod 33. After that, the electromagnet 62 is activated, and the magnetic force generated by it drives the slider 66 and the heating rod 67 to move downward until the proximity capsule 71 contacts the inner wall of the tubular optical glass. The heating rod 67 is heated at this time, so that the proximity liquid 72 in the proximity capsule 71 reaches a molten state. When the proximity capsule 71 contacts the burr protrusion on the inner wall of the tubular optical glass 25, the heating rod 67 is turned off, and the proximity liquid 72 cools and solidifies at the burr protrusion to form a protruding mark. During this process, the piezoelectric film in the proximity capsule 71 senses the burr pressure and generates voltage, activating the electrochromic material inside the proximity capsule to change its color. The color capture camera 68 monitors these color changes and transmits the color change data to the processing unit. The processing unit analyzes the color change data through a positioning algorithm to determine the exact position of the burr. Based on this information, the grinding head 42 is precisely controlled to move to a specified position to grind the burr to remove the uneven inner wall portion.
