Description

Technical Field

[0001] This utility model relates to the field of optical glass manufacturing technology, and more specifically, to a polishing device for optical glass manufacturing. Background Technology

[0002] In the field of optical glass manufacturing, polishing is a critical processing step, and its technological level and waste disposal directly affect product quality and environmental protection. However, existing polishing equipment has many technical shortcomings in practical applications, which are mainly reflected in the following aspects:

[0003] First, in the existing process, the polishing process generates a large number of fine glass fragments. These fragments are fully mixed with the polishing liquid. Due to the lack of an effective separation mechanism, the mixed waste liquid is difficult to process. Especially in the process of mass production, this crude waste disposal method will increase environmental protection costs and is not conducive to the recycling of polishing liquid.

[0004] Secondly, existing polishing equipment has significant shortcomings in the control of polishing slurry delivery. Traditional equipment lacks an effective flow regulation mechanism and cannot accurately control the dripping speed of the polishing slurry. This crude delivery method not only easily leads to waste of polishing slurry, but more importantly, it affects the stability of the polishing process. Especially in high-precision processing where the amount of polishing slurry needs to be precisely controlled, this unadjustable delivery method seriously affects the processing quality and efficiency.

[0005] More importantly, although some improved polishing devices have appeared on the market, attempting to control the delivery speed of polishing slurry by adding speed control devices, these devices still have serious defects in terms of structural reliability. Specifically, although these speed control devices can theoretically adjust the droplet acceleration of polishing slurry, their structural design is too simple and lacks necessary shockproof and stabilization measures. During actual operation of the equipment, especially under the influence of continuous vibration generated by the high-speed rotation of the grinding disc, these simple speed control structures are prone to loosening and displacement. This structural instability will cause deviations in the originally adjusted delivery speed, which will not only affect the polishing effect, but may also cause excessive or insufficient polishing slurry.

The dispensing device includes a dropper 2, a mounting frame 3, and a connecting tube 4. The dropper 2 is mounted on the mounting frame 3, and the connecting tube 4 is positioned above the dropper 2. A control device is connected to the top of the dropper 2. The control device includes a fixed tube 5, a control sleeve 6, a rigid tube 7, a sleeve 8, a flow hole 9, an adapter block 10, a plug rod 11, and an adapter groove 12. The two ends of the control sleeve 6 are rotatably connected to the fixed tube 5 and the rigid tube 7, respectively. The rigid tube 7 is fixedly connected to the mounting frame 3. The fixed tube 5 is fixedly connected to the connecting tube 4. The sleeve 8 is sleeved on the outside of the plug rod 11. Multiple flow holes 9 spirally penetrate the sidewall of the sleeve 8. The adapter block 10... The adapter 10 is spirally fixed on the outside of the plug rod 11. The adapter groove 12 is spirally opened on the inside of the sleeve 8. The adapter block 10 is slidably disposed in the adapter groove 12. A limiting mechanism is provided on the outside of the fixed tube 5. The limiting mechanism includes a limiting sleeve 13, a positioning sleeve 14, a connecting spring 15, an insert rod 16, a slot 17, a movable rod 18, and a movable hole 19. The limiting sleeve 13 is rotatably sleeved on the outside of the fixed tube 5. The positioning sleeve 14 is slidably sleeved on the outside of the fixed tube 5. One end of the insert rod 16 is connected to the outer wall of the control sleeve 6 through the connecting spring 15. Multiple slots 17 are opened on the outside of the fixed tube 5. The other end of the insert rod 16 is inserted into the slot 17. The movable rod 18 is fixedly connected to one side of the positioning sleeve 14. The movable hole 19 is opened on the limiting sleeve 13.

[0032] The inner wall of the control sleeve 6 is connected to a connecting rod 20, and the inner side of the control sleeve 6 is provided with a sliding sleeve 21. The inner wall of the control sleeve 6 is fixedly connected to the outer wall of the sliding sleeve 21 through the connecting rod 20. One end of the blocking rod 11 is connected to a sliding rod 22, and the sliding rod 22 and the sliding sleeve 21 are slidably connected.

[0033] A connecting plate 23 is fixedly installed inside the fixed tube 5, and the inner wall of the fixed tube 5 is fixedly connected to the outer wall of the sleeve 8 through the connecting plate 23.

[0034] A movable spring 24 is movably sleeved on the outer side of the movable rod 18. One end of the movable spring 24 is connected to the positioning sleeve 14, and the other end of the movable spring 24 is in contact with the limiting sleeve 13.

[0035] In this embodiment, when it is necessary to adjust the acceleration of the polishing liquid droplets, firstly, the limiting sleeve 13 is rotated, causing the limiting sleeve 13 to move the movable hole 19. When the movable hole 19 moves to a position concentric with the movable rod 18, the positioning sleeve 14 is pushed, causing the positioning sleeve 14 to drive the movable rod 18 through the movable hole 19. The positioning sleeve 14 and the limiting sleeve 13 cooperate to compress the movable spring 24. When the movable spring 24 is compressed to its limit, the positioning sleeve 14 no longer limits the positioning rod. Then, the control sleeve 6 is rotated, causing the control sleeve 6 to move the multiple insertion rods 16 provided on the side wall. Then, the side wall of the slot 17 will compress one end of the insertion rod 16. The rounded corners at the end of the insertion rod 16 and the rounded corners at the edge of the slot 17 allow one end of the insertion rod 16 to slide out of the slot 17, while the other end of the insertion rod 16 stretches the connecting spring 15. Simultaneously, the control sleeve 6 rotates the sliding sleeve 21 via the connecting rod 20. Due to the prismatic structure of the sliding sleeve 21 and the sliding rod 22, the sliding sleeve 21 rotates the sliding rod 22, which in turn rotates the plug rod 11 connected at one end. The plug rod 11 then causes the outer adapter block 10 to slide along the adapter groove 12. Since the adapter block 10 is slidably positioned in the adapter groove 12, and because the adapter groove 12 and the adapter block... The unique spiral structure design allows the blocking rod 11 to drive the sliding rod 22 to slide along the sliding sleeve 21. The blocking rod 11 also slides spirally along the sleeve 8, changing the number of flow holes 9 blocked by the blocking rod 11. This alters the volume of polishing fluid passing through, thus adjusting the delivery speed of the polishing fluid and consequently adjusting the dripping speed. After proper adjustment, the control sleeve 6 is stopped, and the connecting spring 15 drives the insertion rod 16 to slide and reset. One end of the insertion rod 16 is then inserted into the corresponding slot 17. The positioning sleeve 14 is then released, and the movable spring 24 pushes the positioning sleeve 14... The positioning sleeve 14 drives the movable rod 18 to slide and reset. After the movable spring 24 is completely reset, the limiting sleeve 13 is rotated again, causing the limiting sleeve 13 to move the movable hole 19 to a position that does not correspond to the movable rod 18. Then the movable rod 18 will provide stable support for the positioning sleeve 14, preventing the positioning sleeve 14 from sliding. Then the inner wall of the positioning sleeve 14 will again limit the outer end of the insertion rod 16, preventing the insertion rod 16 from moving. Then the insertion rod 16 and the slot 17 will cooperate to limit the control sleeve 6 again, preventing the control sleeve 6 from rotating, thus ensuring the structural stability after the flow rate adjustment.

[0036] Please see Figures 1-3 As a further embodiment of the dripping device: a drive assembly 25 is provided on one side of the mounting bracket 3, the mounting bracket 3 is movably mounted on one side of the drive assembly 25, and a fixing bracket 26 is provided below the drive assembly 25, the drive assembly 25 is detachably mounted on the fixing bracket 26.

[0037] A support frame 27 is provided on one side of the fixed frame 26, and a placement plate 28 is provided on the support frame 27. Multiple through holes 29 are provided on the placement plate 28.

[0038] A feeding bin 30 is fixedly installed on the inner side of the support frame 27, and a chip collection box 31 is installed below the feeding bin 30.

[0039] The dust collection box 31 is equipped with a detachable filter box 32. The bottom of the filter box 32 has multiple filter holes 33, and the top of the filter box 32 is connected to a handle 34.

[0040] More specifically, when the equipment is needed, the glass is first placed on the placement plate 28, and then the glass is stably clamped onto the placement plate 28 by the external clamping device. Then, the drive assembly 25 is turned on to drive the polishing assembly 1 to move, and then the polishing assembly 1 is turned on to polish the glass. At the same time, the external delivery pump is turned on to deliver the polishing liquid, which is then delivered to the dropper 2 through the connecting pipe 4, the fixed pipe 5, and the rigid pipe 7. The liquid is then dripped onto the glass surface through the dropper 2. The waste liquid will carry the waste The debris enters the feeding hopper 30 through the through hole 29 on the placement plate 28, and then enters the filter box 32 set below through the feeding hopper 30. The waste liquid enters the debris collection box 31 through the filter hole 33 at the bottom of the filter box 32, while the debris remains inside the filter box 32. When the filter box 32 or the debris collection box 31 is full, the equipment is briefly shut down, and then the debris collection box 31 is pulled out. Then, the filter box 32 is taken out from the debris collection box 31 through the handle 34, and then the waste liquid and debris are separated for further processing.

[0041] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the acceleration of the polishing liquid droplets, first rotate the limiting sleeve 13, causing the limiting sleeve 13 to move the movable hole 19. When the movable hole 19 moves to a position concentric with the movable rod 18, push the positioning sleeve 14, causing the positioning sleeve 14 to move the movable rod 18 through the movable hole 19. The positioning sleeve 14 will cooperate with the limiting sleeve 13 to compress the movable spring 24. When the movable spring 24 is compressed to its limit, the positioning sleeve 14 will no longer limit the positioning rod. Then rotate the control sleeve 6, which will drive the multiple insertion rods 16 set on the side wall to move. Then the side wall of the slot 17 will press against one end of the insertion rod 16. When the insertion rod 16 is compressed, due to the rounded corner design at the end of the insertion rod 16 and the rounded corner treatment at the edge of the slot 17, one end of the insertion rod 16 will slide out of the slot 17, and the other end of the insertion rod 16 will drive the connecting spring 15 to stretch. At the same time, the control sleeve 6 will drive the sliding sleeve 21 to rotate through the connecting rod 20. Due to the prismatic structure design of the sliding sleeve 21 and the sliding rod 22, the sliding sleeve 21 will drive the sliding rod 22 to rotate, and the sliding rod 22 will drive the plug rod 11 connected at one end to rotate. Then the plug rod 11 will drive the outer adapter block 10 to slide along the adapter groove 12. Since the adapter block 10 is slidably set in the adapter groove 12, and since the adapter groove 1 2. The adapter block 10 has a special spiral structure design. Then, the blocking rod 11 will drive the sliding rod 22 to slide along the sliding sleeve 21, and the blocking rod 11 will slide spirally along the sleeve 8. Then, the number of flow holes 9 opened on the side wall of the sleeve 8 blocked by the blocking rod 11 will change, so that the volume of polishing liquid passing through will change, thereby adjusting the delivery speed of polishing liquid, and thus achieving the purpose of adjusting the drip acceleration of polishing liquid. After the adjustment is appropriate, stop rotating the control sleeve 6, and cause the connecting spring 15 to drive the insertion rod 16 to slide and reset. Then, one end of the insertion rod 16 will be inserted into the corresponding slot 17. Then, release the positioning sleeve 14, and the movable spring 24 will push the positioning... The sleeve 14 slides back to its original position, causing the positioning sleeve 14 to drive the movable rod 18 to slide back to its original position. After the movable spring 24 has completely reset, the limiting sleeve 13 is rotated again, causing the limiting sleeve 13 to drive the movable hole 19 to move to a position that does not correspond to the movable rod 18. Then the movable rod 18 will provide stable support for the positioning sleeve 14, preventing the positioning sleeve 14 from sliding. Then the inner wall of the positioning sleeve 14 will again limit the outer end of the insertion rod 16, preventing the insertion rod 16 from moving. Then the insertion rod 16 and the slot 17 will cooperate to limit the control sleeve 6 again, preventing the control sleeve 6 from rotating, thereby ensuring the structural stability after the flow rate adjustment.

[0042] When the equipment is needed, first place the glass on the placement plate 28, then use the external clamping device to stably clamp the glass onto the placement plate 28. Next, turn on the drive assembly 25 to move the polishing assembly 1, then turn on the polishing assembly 1 to polish the glass. Simultaneously, turn on the external delivery pump to deliver the polishing fluid, which is then delivered to the dropper 2 through the connecting pipe 4, fixed pipe 5, and rigid pipe 7. The fluid is then dripped onto the glass surface through the dropper 2. Waste liquid carrying waste debris will then be discharged through the dropper. The waste liquid enters the feeding bin 30 through the through hole 29 on the placement plate 28, and then enters the filter box 32 set below through the feeding bin 30. The waste liquid then enters the chip collection box 31 through the filter hole 33 at the bottom of the filter box 32, while the debris remains inside the filter box 32. When the filter box 32 or the chip collection box 31 is full, the equipment is briefly shut down, and then the chip collection box 31 is pulled out. Then, the filter box 32 is taken out from the chip collection box 31 through the handle 34, and the waste liquid and debris are then separated for further processing.
