A polishing device for irregular curved glass

Abstract

This invention discloses a polishing device for irregularly shaped curved glass, which uses an annular airbag to perform flexible polishing of irregularly shaped curved glass. The centrifugal force of the airbag reduces debris residue in the polishing area to improve surface quality. At the same time, a spray hood with an internal arc-shaped channel and nozzles evenly sprays cutting fluid onto the outer wall of the airbag and guides it to the polishing area, thereby improving lubrication uniformity and reducing splashing. The spray hood can be tilted in the polishing direction, and its guiding effect allows excess cutting fluid to cover the glass surface in front of the airbag to enhance wetting and filling effects. In addition, the added partition ring confines the cutting fluid within the inner cavity of the spray hood, thereby increasing its contact area and time with the outer wall of the airbag to improve wetting efficiency. The blades on the partition ring can use centrifugal force to throw the cutting fluid towards the inner wall of the spray hood and splash it onto the surface of the annular airbag during spraying, improving the spraying and cleaning effect.

Description

Technical Field

[0001] This invention relates to the field of polishing, and in particular to a polishing apparatus for irregularly shaped curved glass. Background Technology

[0002] Irregularly shaped curved glass presents a severe challenge to the polishing process due to its complex curved structure. Traditional rigid polishing tools are difficult to adapt to changes in curvature, which can easily lead to over-polishing or under-polishing. Moreover, the glass debris generated during the polishing process is not easy to remove, affecting the surface quality. Airbag polishing technology, as a flexible polishing method, adapts to the curved glass surface by inflating airbags, which improves the fit problem to a certain extent. However, existing airbag polishing devices still have problems such as uneven supply of cutting fluid and incomplete removal of debris in the polishing area, which restricts the further improvement of polishing efficiency and final precision.

[0003] The existing patent with publication number CN115946023B discloses an airbag polishing component, an airbag polishing device, and an airbag polishing equipment. By attaching a liquid storage component with a liquid storage chamber and a liquid passage hole to the inner wall of the airbag, and connecting the liquid storage chamber to the liquid outlet hole of the airbag through a liquid inlet pipe and a liquid passage hole, and applying air pressure to the liquid storage component through the air passage on the base, the pressure is transmitted to the airbag. This allows the polishing liquid stored in the liquid storage chamber to continuously and evenly penetrate into the contact polishing area between the airbag and the workpiece, thereby effectively improving the utilization efficiency and coverage uniformity of the polishing liquid, reducing the wear of the airbag during the polishing process, and ultimately achieving a polishing effect with higher precision and stability.

[0004] Patent application CN104723216B discloses a disc-shaped arc-shaped airbag polishing head. This head is constructed by injection molding an annular airbag into an annular airbag bracket and pressing it into a groove in a disc-shaped wheel hub. Airbag bead seats that fit snugly are placed at both ends of the airbag opening. Bearings are installed on steps at both ends of the wheel hub shaft, creating a stable double-sided support structure for the polishing head. Combined with an air intake channel in the wheel hub connecting the air inlet to the airbag cavity, the polishing force and surface quality can be flexibly controlled by adjusting the gas pressure. This overall design significantly improves the dynamic balance, rigidity, and positioning accuracy of the polishing head under high-speed rotation, resulting in superior polishing effects and processing efficiency.

[0005] The aforementioned prior art discloses a technical solution for uniformly injecting cutting fluid into the polishing position by using a fluid storage component that is attached to the inner wall of the spherical crown airbag and has a fluid storage cavity and a fluid passage hole. It also discloses a technical solution for radial centrifugal polishing using an arc-shaped airbag. However, the prior art still has shortcomings. Opening holes on the surface of the spherical crown airbag affects the stability of the airbag polishing pressure, and the arc-shaped airbag that can perform radial centrifugal polishing is prone to throwing the sprayed cutting fluid into the non-polishing area. Summary of the Invention

[0006] The core of this invention lies in solving the problem of poor contact between cutting fluid and polishing position in the prior art by using a spray hood with an adjustable tilt angle. At the same time, the contact effect between cutting fluid and airbag is further improved by using a spacer ring and blades.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A polishing device for irregular curved glass includes an airbag polishing mechanism. The airbag polishing mechanism includes a mounting frame, a rotating disk is provided inside the mounting frame, and a rotating shaft is fixedly connected to both ends of the rotating disk. The rotating shaft extends to the outside of the mounting frame and is rotatably connected to the mounting frame. One end of one of the rotating shafts is connected to a first driving mechanism that drives it to rotate. An annular airbag is fixedly connected to the outer wall of the rotating disk. An air inlet channel extending to the end of the rotating shaft is opened inside the rotating disk. One end of the air inlet channel communicates with the inner cavity of the annular airbag, and the other end communicates with an external air source.

[0009] A spray hood is provided on the outside of the annular airbag. A rotating shaft passes through the spray hood and is rotatably connected to it. The spray hood is connected to a second drive mechanism that drives its rotation. An arc-shaped channel is provided inside the shell of the spray hood, which is concentric with the annular airbag. The arc-shaped channel is connected to multiple equally spaced spray holes. The opening direction of the spray holes is towards the annular airbag. The arc-shaped channel is connected to an external cutting fluid supply mechanism through a combination of channels opened on the spray hood and the rotating shaft.

[0010] Furthermore, the channel assembly includes a second radial channel formed within the spray hood housing wall and communicating with the arc-shaped channel. A rotating ring is fixedly connected to the first rotating shaft. An annular groove for the rotating ring to rotate is formed inside the spray hood. An annular cavity is formed between the outer wall of the rotating ring and the inner wall of the annular groove. The second radial channel communicates with the annular cavity. An axial channel communicating with the annular cavity is formed inside the first rotating shaft. The inner end of the axial channel communicates with the annular cavity through the first radial channel. The outer end of the axial channel extends to the outer end face of the first rotating shaft. The outer end of the axial channel communicates with an external cutting fluid supply mechanism.

[0011] Furthermore, the rotating ring has a circular structure, and a radial channel is opened on the rotating ring and passes through the rotating ring.

[0012] Furthermore, the first drive mechanism includes a passive gear fixedly connected to a rotating shaft, the passive gear meshing with a drive gear, the drive gear being fixedly connected to the output shaft of a motor, and the housing of the motor being fixedly connected to the side wall of the mounting bracket.

[0013] Furthermore, the second drive mechanism includes a gear ring fixedly connected to the outer wall of the spray hood. The gear ring is coaxially arranged with the rotating shaft. The gear ring meshes with a second drive gear. The second drive gear is fixedly connected to a second rotating shaft. The second rotating shaft passes through the mounting frame and is rotatably connected to the mounting frame. A worm gear is fixedly connected to the outer end of the second rotating shaft. The worm gear meshes with a worm. The upper end of the worm is fixedly connected to the output shaft of a second motor. The housing of the second motor is fixedly connected to the side wall of the mounting frame.

[0014] Furthermore, the spray hood is a semi-circular cover with a U-shaped cross-section, the spray holes are radial openings, the second radial channel is opened along the radial direction of the spray hood, and the first rotating shaft is integrally formed with the rotating disk.

[0015] Furthermore, spacer rings are fixedly connected to both sides of the rotating disk, and an arc-shaped groove is provided on the inner wall of the spray hood for the spacer rings to rotate. The spacer rings are slidably connected to the inner wall of the arc-shaped groove.

[0016] Furthermore, the spacer ring has a circular ring structure, the rotating disk has a circular disk structure, the spacer ring and the rotating disk are concentrically arranged, and the arc groove is a semi-circular groove.

[0017] Furthermore, multiple blades evenly distributed in a circular pattern are fixedly connected to the outer wall of the diaphragm, with the blades located between the side wall of the rotating disk and the inner wall of the spray hood.

[0018] Furthermore, its usage includes the following steps:

[0019] Step 1: Fix the airbag polishing mechanism to the external industrial robotic arm, start the second drive mechanism, the second drive mechanism drives the spray hood to rotate, so that the spray hood tilts in the polishing direction, and the second drive mechanism is turned off after the set tilt angle is reached.

[0020] Step 2: Start the first drive mechanism and external air source to fill the annular airbag with a predetermined volume of gas. Then, the first drive mechanism drives the annular airbag to rotate in a circle. At the same time, the external industrial robotic arm drives the airbag polishing mechanism to move and polish the surface of the irregular curved glass, so that the rolling direction of the annular airbag on the surface of the irregular curved glass is consistent with the polishing direction.

[0021] Step 3: While polishing, start the external cutting fluid supply mechanism. The external cutting fluid supply mechanism injects cutting fluid into the arc-shaped channel through the combination of channels opened in the rotating shaft and the spray hood. Then the cutting fluid is sprayed onto the outer wall of the annular airbag through the spray hole.

[0022] Compared with the prior art, the advantages of this invention are:

[0023] (1) The present invention uses a rotating annular airbag to perform flexible polishing of irregular curved glass. The centrifugal force generated when the annular airbag rotates reduces the residue of glass debris at the polishing position and improves the polishing quality. At the same time, the spray hood with arc-shaped channels and nozzles reduces the splashing of cutting fluid and makes the cutting fluid evenly sprayed onto the outer wall of the annular airbag and flow along the outer wall of the annular airbag to the polishing position, further improving the uniformity of the distribution of cutting fluid on the annular airbag. In addition, the spray hood is tilted to the polishing direction when the annular airbag is polishing. The guiding effect of the spray hood makes the cutting fluid that has separated from the spray hood and the annular airbag throw towards the glass surface in front of the annular airbag in the polishing direction, further improving the filling effect of the cutting fluid.

[0024] (2) The present invention uses a partition ring to confine the cutting fluid sprayed into the spray hood within the cavity between the partition ring and the spray hood, thereby increasing the probability of the cutting fluid contacting the outer circumference of the annular airbag and improving the wetting effect on the annular airbag. In addition, the blades evenly distributed on the partition ring cause the cutting fluid entering between the partition ring and the spray hood to be centrifugally thrown towards the inner wall of the spray hood and splashed onto the annular airbag after impact, further improving the spraying and cleaning effect.

[0037] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0038] First implementation method

[0039] Please see Figures 1-3 In one embodiment of the present invention, a non-circular curved glass polishing device includes an airbag polishing mechanism; the airbag polishing mechanism includes a mounting frame 1, a rotating disk 2 is provided on the inner side of the mounting frame 1, and a rotating shaft 3 is fixedly connected to both ends of the rotating disk 2. The rotating shaft 3 extends to the outer side of the mounting frame 1 and is rotatably connected to the mounting frame 1. One end of one of the rotating shafts 3 is connected to a first driving mechanism that drives it to rotate. An annular airbag 4 is fixedly connected to the outer wall of the rotating disk 2. An air inlet channel 201 extending to one end of the rotating shaft 3 is opened in the rotating disk 2. One end of the air inlet channel 201 communicates with the inner cavity of the annular airbag 4, and the other end communicates with an external air source.

[0040] A spray hood 8 is provided on the outside of the annular airbag 4. A rotating shaft 3 passes through the spray hood 8 and is rotatably connected to it. The spray hood 8 is connected to a second drive mechanism that drives its rotation. An arc-shaped channel 801 is provided inside the shell wall of the spray hood 8, which is concentric with the annular airbag 4. The arc-shaped channel 801 is connected to a plurality of equally spaced spray holes 802. The opening direction of the spray holes 802 faces the annular airbag 4. The arc-shaped channel 801 is connected to an external cutting fluid supply mechanism through a combination of channels opened on the spray hood 8 and the rotating shaft 3.

[0041] Specifically, the polishing process for irregularly shaped curved glass includes the following steps:

[0042] Step 1: Fix the airbag polishing mechanism onto the external industrial robotic arm (not shown in the figure), start the second drive mechanism, the second drive mechanism drives the spray hood 8 to rotate, so that the spray hood 8 tilts in the polishing direction to reach the set tilt angle, and then turn off the second drive mechanism.

[0043] It should be noted that the irregular curved glass is clamped on the worktable (not shown in the figure), and the industrial robotic arm is also fixed on the worktable. Both the worktable and the industrial robotic arm are existing technologies, and will not be described in detail in this application.

[0044] Step 2: Start the first drive mechanism and external air source to fill the annular airbag 4 with a predetermined volume of gas. Then, the first drive mechanism drives the annular airbag 4 to rotate in a circle. At the same time, the external industrial robotic arm drives the airbag polishing mechanism to move and polish the surface of the irregular curved glass, so that the rolling direction of the annular airbag 4 on the surface of the irregular curved glass is consistent with the polishing direction.

[0045] Step 3: While polishing, the external cutting fluid supply mechanism is activated. The external cutting fluid supply mechanism injects cutting fluid into the arc-shaped channel 801 through the combination of channels opened in the rotating shaft 3 and the spray hood 8. Then the cutting fluid is sprayed onto the outer wall of the annular airbag 4 through the spray hole 802.

[0046] For details, please refer to Figure 7 and Figure 8 The cutting fluid is sprayed onto the surface of the annular airbag 4 using the spray hood 8. Under the combined action of the guiding effect of the inclined spray hood 8 and the centrifugal effect of the annular airbag 4, the cutting fluid is fully in contact with the surface of the annular airbag 4. The cutting fluid that is separated from the spray hood 8 drips onto the glass on the front side of the annular airbag 4 in the direction of travel under the guiding effect of the spray hood 8.

[0047] It should be noted that the annular airbag 4 is existing technology, which generally includes an inner rubber layer, a middle steel plate support layer, an outer rubber layer, and a polishing pad bonded to the outer rubber layer. The polishing pad is generally made of non-woven fabric material, which uses its porous fiber structure to adsorb abrasive and cutting fluid. This application will not elaborate further.

[0048] Compared to traditional glass polishing devices, this invention uses an annular airbag 4 and a spray hood 8 to perform flexible polishing of irregularly shaped curved glass. The centrifugal force generated by the rotation of the annular airbag 4 reduces glass debris residue at the polishing position, improving polishing quality. Simultaneously, the annular airbag 4 and the spray hood 8 work together to ensure that the cutting fluid is evenly sprayed onto the outer wall of the annular airbag 4 and flows along it to the polishing position, further enhancing the polishing effect. Furthermore, the angle-adjustable spray hood 8 tilts towards the polishing direction during polishing, causing the cutting fluid to drip onto the glass surface in front of the annular airbag 4 in the polishing direction, further improving the filling effect of the cutting fluid and the polishing quality.

[0049] Please see Figures 3-6The channel assembly includes a second radial channel 803 formed inside the shell wall of the spray hood 8 and communicating with the arc-shaped channel 801. A rotating ring 302 is fixedly connected to the rotating shaft 3. An annular groove 804 is formed inside the spray hood 8 to allow the rotating ring 302 to rotate. An annular cavity is formed between the outer wall of the rotating ring 302 and the inner wall of the annular groove 804. The second radial channel 803 communicates with the annular cavity. An axial channel 301 is formed inside the rotating shaft 3 and communicates with the annular cavity. The inner end of the axial channel 301 communicates with the annular cavity through the first radial channel 303. The rotating ring 302 has a circular ring structure. The first radial channel 303 is formed on the rotating ring 302 and passes through the rotating ring 302. The outer end of the axial channel 301 extends to the outer end face of the rotating shaft 3. The outer end of the axial channel 301 communicates with the external cutting fluid supply mechanism.

[0050] Specifically, the external cutting fluid supply mechanism (not shown in the figure) injects cutting fluid into the annular cavity through the axial channel 301 and the radial channel 303. Then, the cutting fluid is injected into the arc-shaped channel 801 through the radial channel 803, thus realizing the supply of cutting fluid. It should be noted that the external cutting fluid supply mechanism includes a delivery pump and a cutting fluid storage tank. The input pipe of the delivery pump is connected to the cutting fluid storage tank, and the output pipe is rotatably connected to the rotating shaft 3 through a rotary joint.

[0051] Please see Figure 2 and Figure 3 The first drive mechanism includes a passive gear 5 fixedly connected to the rotating shaft 3, the passive gear 5 meshing with a drive gear 6, the drive gear 6 fixedly connected to the output shaft of a motor 7, and the housing of the motor 7 fixedly connected to the side wall of the mounting bracket 1.

[0052] Specifically, motor 7 drives drive gear 6 to rotate, drive gear 6 drives shaft 3 to rotate through passive gear 5, and shaft 3 drives rotating disk 2 and annular airbag 4 to rotate.

[0053] Please see Figure 1 and Figure 3 The second drive mechanism includes a gear ring 9 fixedly connected to the outer wall of the spray hood 8. The gear ring 9 is coaxially arranged with the rotating shaft 3. The gear ring 9 meshes with a drive gear 10. The drive gear 10 is fixedly connected to a rotating shaft 11. The rotating shaft 11 passes through the mounting frame 1 and is rotatably connected to the mounting frame 1. A worm gear 12 is fixedly connected to the outer end of the rotating shaft 11. The worm gear 12 meshes with a worm 13. The upper end of the worm 13 is fixedly connected to the output shaft of a motor 14. The housing of the motor 14 is fixedly connected to the side wall of the mounting frame 1.

[0054] Specifically, motor 14 drives worm 13 to rotate, worm 13 drives shaft 11 to rotate via worm wheel 12, shaft 11 drives spray hood 8 to rotate via drive gear 10 and gear ring 9, thereby adjusting the tilt angle of spray hood 8; in addition, the self-locking effect of worm 13 and worm wheel 12 is used to lock and fix spray hood 8; it should be noted that a Hall sensor is installed inside motor 14, which is used to monitor the angle and position of the output shaft of motor 14, thereby monitoring the rotation angle and position of spray hood 8.

[0055] Please see Figure 1 , Figure 5 and Figure 6 The spray hood 8 is a semi-circular cover with a U-shaped cross section. The spray hole 802 is a radial opening. The radial channel 803 is opened along the radial direction of the spray hood 8. The rotating shaft 3 is integrally formed with the rotating disk 2.

[0056] Specifically, the spray hood 8 reduces the splashing of cutting fluid and improves the contact effect between the cutting fluid and the annular airbag 4.

[0057] Second implementation method

[0058] Based on the first implementation, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 10 The rotating disk 2 has spacer rings 15 fixedly connected to both sides of the rotating disk 2. The inner wall of the spray hood 8 has an arc-shaped groove 805 for the spacer rings 15 to rotate. The spacer rings 15 are slidably connected to the inner wall of the arc-shaped groove 805.

[0059] Specifically, the rotating disk 2, the spray hood 8, and the partition ring 15 form an annular gap with openings at both ends. The portion of the annular airbag 4 located inside the spray hood 8 rotates within the annular gap, and the sprayed cutting fluid is confined within the annular gap, further increasing the contact probability between the cutting fluid and the annular airbag 4 and improving the wetting effect of the cutting fluid on the surface of the annular airbag 4.

[0060] Please see Figure 3 , Figure 4 and Figure 5 The spacer ring 15 is a circular ring structure, the rotating disk 2 is a circular disk structure, the spacer ring 15 and the rotating disk 2 are concentrically arranged, and the arc groove 805 is a semi-circular groove.

[0061] Specifically, the cutting fluid is confined within the annular gap by the spacer ring 15, thereby reducing the amount of cutting fluid used and improving the utilization efficiency of the cutting fluid.

[0062] Please see Figure 3 and Figure 9Multiple blades 16 are fixedly connected to the outer wall of the partition ring 15 in a circumferentially evenly distributed manner. The blades 16 are located between the side wall of the rotating disk 2 and the inner wall of the spray hood 8.

[0063] Specifically, when the annular airbag 4 needs to be cleaned, the external industrial robotic arm lifts the airbag polishing mechanism away from the worktable. Then, the second drive mechanism rotates the spray hood 8, causing it to tilt to one side. Next, the external cutting fluid supply mechanism is activated to inject cutting fluid into the spray hood 8. Then, the first drive mechanism is activated, and the rotating disk 2 rotates the annular airbag 4, with the rotation direction of the annular airbag 4 consistent with the tilt direction (see [link to relevant documentation]). Figure 10 The annular airbag 4 is rotated and cleaned. The washing action of the cutting fluid and the centrifugal force generated by the rotation of the annular airbag 4 cause glass fragments to detach from the surface polishing pad of the annular airbag 4. The glass fragments detached from the polishing pad are discharged outward along the inner wall of the spray hood 8 with the cutting fluid. The rotation cleaning improves the cleanliness of the surface polishing pad of the annular airbag 4, avoids the accumulation of glass fragments in the surface polishing pad of the annular airbag 4, thereby improving the polishing quality and extending the service life of the annular airbag 4.

[0064] After cleaning, the annular airbag 4 is manually inspected. If any residual glass fragments are found, they are manually cleaned to reduce the amount of glass fragments remaining after rotation cleaning. In addition, during polishing spraying and rotation cleaning, the centrifugal force generated by the blades 16 is used to throw the cutting fluid towards the inner wall of the spray hood 8. After the cutting fluid collides with the inner wall of the spray hood 8, it bounces back and splashes onto the annular airbag 4, improving the cutting fluid replenishment and cleaning effect.

[0065] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
