Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of curved glass processing, in particular to a polishing mechanism for curved glass and a polishing method thereof. BACKGROUND

[0002] Vehicle display panels include central control display panels, instrument display panels, head-up display screens, electronic rearview mirror display screens, rear seat entertainment display screens, and the like.

[0003] In recent years, the vehicle panel market has shown a trend of large screens (such as Figure 5 The central control display panel and the instrument display panel are integrated), so there are matching 3D glass panels (or 3D large curved glass, or curved glass pieces). Because the 3D glass panel has the characteristics of lightness, anti-fingerprint, anti-glare, and resistance to hanging injury; it can realize the bending and folding of the surface of the vehicle display screen, and still achieve high-quality display effect after edge bending, thereby realizing seamless connection of the three-dimensional surface in the uneven instrument panel area; and improving the freedom of design and functional integration to further provide the interface function of human-computer interaction and the entertainment carrier, which has become the main trend of future development of vehicle panels.

[0004] The current 3D large curved glass is processed by mold forming; during the forming process, the quality of the 3D large curved glass produced in the first few batches after mold cleaning is good (without small pits); after a period of production, a small amount of material will adhere to the mold when the mold is removed, resulting in a decrease in production quality (the surface is not smooth enough). Currently, many companies on the market use the product after mold forming without subsequent processing directly in the car; although it can meet the basic requirements, it is slightly rough for some high-standard cars. Of course, some companies will polish the product before installing it in the car.

[0005] However, at present, the polishing and grinding processing of vehicle display panels is very simple, using a polishing metal method, such as coarse wax, a grinding machine, a yellow coarse sponge disc, etc., through manual or with the help of very simple mechanical structure for grinding. This grinding method, on the one hand, is low in grinding efficiency, and on the other hand, the quality is uncontrollable, and the pass rate is not ideal.

[0006] Therefore, the company has developed an automatic polishing and grinding equipment for vehicle 3D large curved glass (abandoning the current simple processing method) to improve production efficiency and control polishing quality. The polishing equipment places the curved glass piece in an auxiliary polishing barrel for polishing after grabbing it.

[0007] In order to fully protect the whole, for the fully automated production of polishing processing equipment of multiple main core patent points, through multiple patents are protected respectively. And the scheme, for the "polishing mechanism" part is protected. SUMMARY

[0008] The polishing mechanism for curved glass and the polishing method thereof provided by the present application overcome the defects of the prior art, solve the problems of poor polishing effect, high polishing cost and low polishing efficiency of the traditional polishing method, and have the advantages of high polishing effect, low polishing cost and high polishing efficiency.

[0009] The object of the present application is achieved by the following technical solutions:

[0010] (First aspect)

[0011] The polishing mechanism for curved glass provided by at least one embodiment of the present application comprises a rack, a polishing ball, and the like.

[0012] The rack is in the shape of a barrel rack, and a plurality of polishing balls are arranged on the circumferential side column surface of the rack.

[0013] All the polishing balls are driven to rotate by the same central rotating shaft, and the rotation directions of the polishing balls arranged above and below each other are opposite.

[0014] The rack is further connected with a flexible lifting mechanism.

[0015] The polishing mechanism is placed in a polishing barrel, and the wall of the polishing barrel is provided with a curved glass piece; the central rotating shaft drives the polishing balls to rotate for polishing, the polishing balls rotating in different directions drive the polishing materials in the polishing liquid to overturn in the polishing barrel; and the flexible lifting mechanism allows the polishing balls to make flexible contact with the curved glass piece during polishing.

[0016] For example, the polishing mechanism for curved glass provided by one embodiment of the present application is designed in terms of the directions of the polishing balls. A driving gear is arranged on the central rotating shaft, and a plurality of driven bevel gears are arranged in the circumferential direction of the driving gear; the driven bevel gears are installed on corresponding rotating shafts A, and the rotating shafts A are installed on the rack; the polishing balls are fixed on ball racks, and the ball racks are installed on the rack through rotating shafts B; and the rotating shafts A and the rotating shafts B are drivingly connected. When the rotating shafts B of some polishing balls are directly drivingly connected with the rotating shaft A, the rotation directions of these polishing balls and the rotating shaft A are consistent; and when the rotating shafts B of some polishing balls are drivingly connected with the rotating shaft A through rotating shafts C, the rotation directions of the polishing balls and the rotating shaft A are opposite.

[0017] When the rotation directions of the polishing balls are different, the polishing materials in the polishing liquid in the polishing barrel can be effectively driven to overturn, so that the polishing materials can be fully utilized instead of sinking to the bottom, and the polishing effect is improved. In addition, the mode that one central rotating shaft drives all the polishing balls to move has a simple structure.

[0018] For example, the polishing mechanism for curved glass provided by an embodiment of the present application is designed for a rack. The rack comprises an upper ring frame, a lower ring frame, and vertical unit frames. The upper ring frame and the lower ring frame are connected by the vertical unit frames which are evenly distributed in a circumferential direction. A sleeve is fixed on the upper ring frame, and a central rotating shaft is arranged in the sleeve. The upper end of the central rotating shaft is driven by a main drive motor, and the lower end of the central rotating shaft extends out of the sleeve. The rotating shaft A is installed on the lower surface of the upper ring frame through an auxiliary plate. Two rotating shafts B are installed on the upper part and the lower part of the vertical unit frame respectively, and the rotating shafts B on the upper part and the lower part are referred to as rotating shaft Ba and rotating shaft Bb. The rotating shaft C is also installed on the vertical unit frame. The structure of the entire rack is simple, and the weight is light, which is beneficial to the flexible lifting mechanism to drive the entire rack to move up and down for adjustment.

[0019] Further, the driving of the rotating shaft A and the rotating shaft B is designed. The rotating shaft A is sleeved with a driven bevel gear and a chain wheel A. The rotating shaft C is sleeved with a chain wheel C and a gear C. The rotating shaft Ba is sleeved with a chain wheel Bax and a chain wheel Bay, and the rotating shaft Bb is sleeved with a chain wheel Bb and a gear Bb.

[0020] When the driven bevel gear is connected to the chain wheel Bb through a chain, the gear Bb is engaged with the gear C, and the chain wheel C is connected to the chain wheel Bay through a chain, if the rotating shaft A rotates in a forward direction, the rotating shaft Bb rotates in a forward direction, and the rotating shaft Ba rotates in a reverse direction. When the driven bevel gear is connected to the chain wheel Bax through a chain, the chain wheel Bay is connected to the chain wheel C through a chain, and the gear C is engaged with the gear Bb, if the rotating shaft A rotates in a forward direction, the rotating shaft Ba rotates in a forward direction, and the rotating shaft Ba rotates in a reverse direction. That is, when the rotating shaft A rotates, the polishing balls adjacent in the circumferential direction and the vertical direction can rotate in different directions.

[0021] Further, the vertical unit frame is designed. The vertical unit frame comprises an inner vertical plate, an outer vertical plate, and a horizontal support plate. The inner vertical plate and the outer vertical plate are parallel to each other, and the two ends of the inner vertical plate and the outer vertical plate are fixed and connected by the horizontal support plate. The rotating shaft Ba and the rotating shaft Bb penetrate the vertical unit frame from front to back, and the two ends of the rotating shaft B are fixed between the inner vertical plate and the outer vertical plate. The vertical unit frame is also provided with a rotating shaft D, and a pressure roller is sleeved on the rotating shaft D to press the chain between the chain wheel Bay and the chain wheel C.

[0022] The above-mentioned rack, vertical unit frame, and corresponding driving connection are designed to achieve that a central rotating shaft drives different polishing balls to rotate in different directions. Of course, other selection methods can also be formed by using similar ideas, but as long as similar ideas are used in the field of polishing multiple parts together, they are within the protection scope of the present application.

[0023] For example, the polishing mechanism for curved glass provided by an embodiment of the present application is designed for a flexible lifting mechanism. The flexible lifting mechanism comprises a plurality of lifting chains and a plurality of positioning sprockets. One end of the lifting chain is fixed to the upper surface of the frame, and the other end is wound around the upper positioning sprocket E, then back around the lower positioning sprocket F, and then connected at the lower surface of the frame. The upper positioning sprocket is connected to the lifting motor drive, which drives the lifting chain to move the frame up and down. When the polishing ball is polishing, the frame is mounted on the flexible lifting mechanism, and the polishing ball is in flexible contact with the curved glass piece.

[0024] In addition to driving the frame to move up and down, the flexible lifting mechanism also achieves flexible contact between the polishing ball and the curved glass piece. During the polishing process, the flexible lifting mechanism can automatically sway, so that the polishing ball is in contact with the curved glass piece for polishing at one time, and the polishing ball is separated from the curved glass piece at another time to facilitate the falling of the excess material after polishing.

[0025] (Second aspect)

[0026] The polishing method of the polishing mechanism for curved glass has the following working steps:

[0027] S1, place a basic frame, place a polishing barrel at the bottom of the basic frame, install a displacement motor in the polishing barrel, and install an upper frame on the basic frame; the polishing mechanism is hoisted by the lifting chain;

[0028] S2, install polishing liquid in the polishing barrel, and the polishing liquid has suspended polishing material; a plurality of curved glass pieces are placed circumferentially on the wall of the polishing barrel;

[0029] Start the displacement motor, drive the polishing mechanism to move downward through the lifting chain, and the polishing ball is in flexible contact with the curved glass piece;

[0030] S3, start the main drive motor to drive all the driven bevel gears circumferentially to rotate together through the central shaft, the driven bevel gears drive the corresponding shaft A and shaft Ba to rotate, the shaft Ba drives the polishing ball on the upper part of the outer vertical plate to rotate clockwise through the corresponding ball holder, and the polishing of the curved glass piece is realized;

[0031] At the same time, the shaft Ba also drives the shaft C to rotate through the sprocket Bay and the sprocket C, the shaft C drives the shaft Bb to rotate through the gear C and the gear Bb, and the shaft Bb drives the polishing ball on the lower part of the outer vertical plate to rotate counterclockwise through the corresponding ball holder, and the polishing of the curved glass piece is realized;

[0032] When the polishing ball is polishing, the polishing ball grinds the surface of the curved glass piece through the polishing material, and the polishing material at this position is thrown out by the rotating polishing ball. Since the rotating directions of the polishing balls on the upper part and the lower part of the outer vertical plate are different, the thrown-out polishing material is flipped in the polishing liquid, and after flipping, it is used by another polishing ball.

[0033] In the polishing of the curved glass piece, the polishing ball is subjected to the reaction force of the curved glass piece, which is transmitted to the flexible lifting mechanism through the frame, and the flexible lifting mechanism is flexibly connected with the basic frame, so that the polishing ball is in flexible contact with the curved glass piece. In addition, the reaction force of the polishing ball will cause the frame to sway, and if one side of the polishing ball moves away from the curved glass piece during the frame swaying process, the other side of the polishing ball will move close to the curved glass piece, thereby achieving good polishing effect.

[0034] S4, when the polishing of a certain part of the curved glass piece is completed, the polishing mechanism is driven by the flexible lifting mechanism to continue the up-down displacement adjustment, and the polishing is carried out from another position of the curved glass piece…… until the polishing is completed.

[0035] In order to facilitate understanding, the core design points of the scheme are described:

[0036] I. The frame is flexibly fixed, and the frame is subjected to small-amplitude reciprocating swaying during polishing to improve the polishing effect.

[0037] In the traditional polishing field (mainly metal polishing), considering the material factors such as hardness of metal, the metal piece is usually locked and fixed, and then the polishing ball is installed on the corresponding rotatable mechanical part to polish with abrasive material / abrasive liquid. In the polishing process, only one metal piece can be polished at a time, and the work efficiency is very low. And when the mechanical part drives the polishing ball to work, the polishing ball is always in contact with the metal piece; this makes the abrasive material accumulate more at the polishing site when the initial polishing is performed, and the polishing effect is good, but as the polishing time increases, the accumulated abrasive material is thrown out by the polishing ball, and the polishing effect decreases sharply; and as the polishing time increases, the material removed by grinding is mixed in the abrasive material, thereby causing the polishing effect to decrease sharply. These reasons result in that the polishing degree in the traditional metal polishing process is extremely uncontrollable, so the polishing quality is very uncontrollable. Even with the same equipment, the same amount, the same batch of metal pieces, and the same polishing time, small factors will cause the final polishing result to be different, so the polishing yield is low (for example, the polishing of the inner blade of an aero-engine is so).

[0038] In this scheme, the polishing ball is installed on the side of the rack, and the rack is installed on the flexible lifting mechanism, which is equivalent to the flexible fixation of the rack. During the polishing process, the polishing ball is subjected to the reaction force of the curved glass part, so that the rack presents a slight shaking on the flexible lifting mechanism. This slight shaking can change the gap size between the polishing ball and the surface of the curved glass part. When the gap between the polishing ball and the curved glass part becomes smaller, the polishing ball will squeeze the polishing material on the surface of the curved glass part, achieving grinding and polishing. When the gap between the polishing ball and the curved glass part becomes larger, the polishing material and the residual material ground below are not compressed, and the residual material will sink. The polishing material is not suitable for sinking due to its suspension state in the polishing liquid, and the suspended polishing material will be used for the next polishing.

[0039] II. By rotating the adjacent polishing balls in different directions, the polishing material is turned over in the polishing liquid, so that the polishing material is fully utilized without sinking, thereby improving the polishing effect.

[0040] In the traditional field of metal polishing, when the polishing material is used for polishing, new polishing material is added when the polishing material is thrown out by the corresponding polishing ball. Since the polishing material is prepared by special process, the qualified product rate is not high, and the price is high. Therefore, the method of continuously adding new polishing material during polishing will result in high processing cost, which is difficult for general factories to bear. Moreover, the thrown-out polishing material is very wasteful.

[0041] In this scheme, the polishing material is added to the polishing liquid during polishing, so that the polishing material is suspended in the polishing liquid. During polishing, the entire polishing mechanism and the curved glass part are immersed in the polishing liquid for processing. Therefore, the thrown-out polishing material will still be in the polishing liquid, and the polishing material will participate in the polishing process again with the rolling of the polishing liquid, thereby greatly reducing the processing cost.

[0042] In this scheme, in order to reuse the thrown-out polishing material, the adjacent polishing balls are designed to rotate in different directions. When one polishing ball throws the polishing material to the second adjacent polishing ball, the polishing material is utilized by the second polishing ball. Moreover, the second polishing ball can also throw the polishing material to the first polishing ball. In this way, the polishing material can repeatedly roll in the polishing liquid, thereby being fully utilized.

[0043] III. One central shaft drives all the polishing balls, and the adjacent polishing balls rotate in different directions.

[0044] In the traditional field of metal polishing, only one metal part is polished at a time, so the driving structure of the polishing ball is very simple.

[0045] But in this scheme, because need to immerse the polishing mechanism in the polishing barrel, and to polish multiple curved glass pieces at the same time, must to go to the structure light, simple; The design of the center shaft, shaft A, shaft B, shaft C, and the corresponding design of the chain wheel, gear, simple structure, so that only through a center shaft can drive through multiple polishing balls to rotate at the same time, and also realize the adjacent polishing balls rotate in different directions.

[0046] The present application has the following advantages:

[0047] (1) The polishing mechanism is arranged on the flexible lifting mechanism, so that the rack can swing back and forth in a small range during polishing; The polishing balls rotate in different directions, so that the polishing material can be fully utilized repeatedly; Add polishing material in the polishing liquid, and immerse the polishing mechanism in the polishing liquid in the polishing barrel for processing; Through these measures, the polishing effect of curved glass can be improved;

[0048] And a plurality of curved glass pieces can be polished at one time, and the polishing efficiency is high;

[0049] Moreover, after the polishing material is thrown out by the polishing ball, it still rolls in the polishing liquid, and the polishing material can be repeatedly utilized, thereby greatly saving the polishing cost;

[0050] (2) The driving structure of the polishing ball is simple and ingenious, and all the polishing balls are driven to rotate by a center shaft, and the adjacent polishing balls rotate in different directions; That is, the complex action of the polishing ball is realized by a simple structure.

[0061] The drawings in the application are not strictly drawn according to the actual proportions, and the specific size and quantity of each structure can be determined according to actual needs. The drawings described in the application are only structural schematic diagrams.

[0062] (First aspect)

[0063] It should be noted that the polishing in the polishing field at present is mainly for polishing metal parts, and there is not much polishing for glass parts, especially curved glass parts. Even if there is a polishing mechanism for glass parts, it is also borrowed from the idea of metal polishing. However, glass parts are relatively brittle and cannot be well locked and fixed like metal parts, nor can they be directly rigidly contacted and polished like metal parts. Since the characteristics of curved glass parts are not quite the same as those of metal parts, they cannot share a set of polishing ideas.

[0064] At least one embodiment of the application provides a polishing mechanism for curved glass, such as Figure 1As shown, the polishing mechanism includes a frame 31, polishing balls, and a flexible lifting mechanism 33. The frame 31 is in the shape of a barrel frame, and a plurality of polishing balls are arranged on the circumferential side surface of the frame 31 and are driven to rotate by a same central rotating shaft 32. The rotating directions of the adjacent polishing balls are opposite. The flexible lifting mechanism 33 is hung on the flexible lifting mechanism 33. The lower end of the flexible lifting mechanism 33 is flexibly connected to the inner bottom of the polishing barrel, and the upper end is installed on the upper frame of the basic frame. Moreover, a polishing liquid is arranged in the polishing barrel, and the polishing liquid contains suspended polishing materials. A plurality of curved glass pieces are arranged on the inner side wall of the polishing barrel.

[0065] When working, the frame 31 is lowered by the flexible lifting mechanism 33, so that the polishing balls on the frame 31 are in contact with the curved glass pieces. Then, the polishing balls are driven to rotate by the central rotating shaft 32, so that the polishing balls polish all the curved glass pieces on the polishing barrel together, and the polishing efficiency is high (the metal material is usually hard, so the polishing idea is to polish one piece at a time, and the efficiency is low).

[0066] During the polishing process, the polishing balls remove the rough excess material on the surface of the curved glass pieces by the polishing materials in the polishing liquid, and the polishing balls also shake the polishing materials when rotating. Since the directions of the polishing balls are not the same, the polishing materials that are shaken off will roll in the polishing liquid, so that the polishing materials are fully utilized and are prevented from sinking.

[0067] During the polishing process, the curved glass pieces will exert a reaction force on the polishing balls, so that the frame 31 will sway on the flexible lifting mechanism 33 (in common parlance, the frame 21 will sway on the flexible lifting mechanism 33). Therefore, part of the polishing balls will move away from the curved glass pieces, and part of the polishing balls will move close to the curved glass pieces. When the polishing balls move close to the curved glass pieces, the polishing balls will have a grinding effect, and when the polishing balls move away from the curved glass pieces, the excess material after polishing will sink by itself. (In the current polishing field, when the metal is continuously polished, the polishing balls are fixed by a rigid mechanism or a flexible mechanism. However, the polishing balls are always in contact with the workpiece, so that the excess material after polishing will accumulate on the surface of the workpiece, which will affect the subsequent polishing)

[0068] For example, Figures 1 to 5The installation of the central rotating shaft 32 is shown. The sleeve 40 is fixed on the frame 31, and the main drive motor 41 is fixed on the sleeve 40. The output shaft of the main drive motor 41 is the central rotating shaft 32, which extends out of the sleeve 40. The driving gear 34 is installed on the extending end of the central rotating shaft 32, and the driving gear 34 is circumferentially meshed with a plurality of driven bevel gears 35, which are installed on the frame 31 through the rotating shaft A. The ball holder and the polishing ball are installed on the frame 31 through the rotating shaft B. When some polishing balls are directly connected with the rotating shaft A through the rotating shaft B, the rotating direction of the polishing balls is consistent with that of the rotating shaft A. When some polishing balls are connected with the rotating shaft A through the rotating shaft C, the rotating direction of the polishing balls is opposite to that of the rotating shaft A.

[0069] When the central rotating shaft 32 rotates, it can drive all the driven bevel gears 35 to rotate, and then drive the corresponding polishing balls to rotate clockwise or counterclockwise through the driven bevel gears 35.

[0070] For example, referring to Figures 2 to 5 The frame 31 is designed. The frame 31 includes the upper ring holder 37, the lower ring holder 38, and the vertical unit holder 39. The upper ring holder 37 and the lower ring holder 38 are placed in parallel along the up-down position, and are supported and fixed in the circumferential direction by the vertical unit holder 39. The polishing balls are installed on the vertical unit holder 39 through the ball holder 36.

[0071] In addition, the sleeve 40 is fixed on the upper ring holder 37, and the central rotating shaft 32 is installed in the sleeve 40. The upper end of the central rotating shaft 32 is driven by the main drive motor 41, and the lower end of the central rotating shaft 32 extends out of the sleeve 40.

[0072] In addition, the rotating shaft A is installed on the lower surface of the upper ring holder 37 through the auxiliary plate 50. The two rotating shafts B are installed on the upper and lower parts of the vertical unit holder 39, respectively. The rotating shafts B on the upper and lower parts are called rotating shaft Ba and rotating shaft Bb. The rotating shaft C is also installed on the vertical unit holder 39.

[0073] The structure of the entire frame 31 is very simple, and the weight is light after design and production, which is beneficial to the up-down displacement of the frame 31 under the driving of the flexible lifting mechanism 33.

[0074] For example, preferably, referring to Figure 6 and Figure 7The vertical unit frame 39 is designed. The vertical unit frame 39 comprises inner vertical plates 42, outer vertical plates 43, and horizontal support plates 44. The inner vertical plates 42 and the outer vertical plates 43 are vertically placed and parallel to each other at the inner side and the outer side respectively. The upper ends and the lower ends of the inner vertical plates 42 and the outer vertical plates 43 are fixed and connected by the corresponding horizontal support plates 44. The horizontal support plates 44 are fixed on the upper ring frame 37 and the lower ring frame 38 by bolts. The upper shaft B and the lower shaft B are installed at the upper position and the lower position of the vertical unit frame 39 respectively. The upper shaft B and the lower shaft B are called the upper shaft Ba and the lower shaft Bb respectively. The ends of the upper shaft Ba and the lower shaft Bb are equipped with polishing balls through the corresponding ball frames 36. The polishing balls at the upper position and the lower position are called the upper polishing ball and the lower polishing ball respectively.

[0075] The structure of the vertical unit frame 39 is very simple, which is beneficial to be directly fixed and installed with the upper ring frame 37 and the lower ring frame 38. During operation: if the shaft A directly drives the shaft Bb to rotate, and then the shaft Bb drives the shaft Ba to rotate through the shaft C, the shaft A can drive the shaft Bb to rotate in the positive direction and the shaft Ba to rotate in the negative direction when the shaft A rotates in the positive direction. If the shaft A directly drives the shaft Ba to rotate, and then the shaft Ba drives the shaft Bb to rotate through the shaft C, the shaft A can drive the shaft Ba to rotate in the positive direction and the shaft Bb to rotate in the negative direction when the shaft A rotates in the positive direction.

[0076] For example, referring to Figure 5 The specific driving of the shaft A and the shaft B is designed. The shaft A is equipped with a driven bevel gear 35 and a chain wheel A 51. The shaft C is equipped with a chain wheel C 45 and a gear C 46. The shaft Ba is equipped with a chain wheel Ba x and a chain wheel Ba y 38. The shaft Bb is equipped with a chain wheel Bb 52 and a gear Bb 47.

[0077] When the driven bevel gear 35 and the chain wheel Bb 52 are connected by a chain, the gear Bb 47 and the gear C 46 are engaged, and the chain wheel C 45 and the chain wheel Ba y 38 are connected by a chain: if the shaft A rotates in the positive direction, the shaft Bb rotates in the positive direction and the shaft Ba rotates in the negative direction. When the driven bevel gear 35 and the chain wheel Ba x are connected by a chain, the chain wheel Ba y 38 and the chain wheel C 45 are connected by a chain, and the gear C 46 and the gear Bb 47 are engaged: if the shaft A rotates in the positive direction, the shaft Ba rotates in the positive direction and the shaft Ba rotates in the negative direction. That is, when the shaft A rotates, the upper and lower adjacent polishing balls can rotate in different directions.

[0078] The driving structure formed by the center shaft 32, the driving gear 34, the driven bevel gear, the shaft A, and the shaft B is relatively simple in structure, but it realizes a relatively complex function, that is, through the center shaft 32, the different polishing balls are realized to rotate in different directions, so that the polishing balls drive the polishing material to overturn and avoid the sinking of the polishing material.

[0079] Of course, the above driving structure is only a preferred mode, and other polishing ball rotating modes can be designed by using similar ideas, for example, the rotating directions of the adjacent polishing balls above and below are inconsistent, the rotating directions of the adjacent polishing balls in the circumferential direction are consistent, and only the connection mode of the sprocket and the corresponding gear needs to be slightly changed to achieve the rotating mode, but such ideas are within the protection scope of the present application.

[0080] For example, with reference to Figure 1 The flexible lifting mechanism 33 is designed. The flexible lifting mechanism 33 includes a plurality of lifting chains 49 and a plurality of positioning sprockets. One end of the lifting chain 49 is fixed to the upper surface of the rack 31, and the other end is wound around the upper positioning sprocket E, then wound around the lower positioning sprocket F, and then connected at the lower surface of the rack 31. The upper positioning sprocket is connected to the lifting motor drive, which drives the rack 31 to move up and down through the lifting chain 49. When the polishing ball is polishing, the rack 31 is mounted on the flexible lifting mechanism 33, and the polishing ball is in flexible contact with the curved glass piece.

[0081] In addition to driving the rack 31 to move up and down, the flexible lifting mechanism 33 also realizes the flexible contact between the polishing ball and the curved glass piece. During the polishing process, the rack 31 can slightly shake in the flexible lifting mechanism 33, so that the polishing ball is in contact with the curved glass piece for polishing at times, and the polishing ball is separated from the curved glass piece at times to facilitate the falling of the excess material after polishing, which can better polish the curved glass piece.

[0082] (Second aspect)

[0083] At least one embodiment of the present application provides a polishing method applied to any one of the polishing mechanisms provided by the present application. The polishing steps include the following S1-S4 steps.

[0084] S1, place a basic frame, place a polishing barrel at the bottom of the basic frame, install a displacement motor in the polishing barrel, and install an upper frame on the basic frame; and hoist the polishing mechanism through the lifting chain 49;

[0085] S2, install polishing liquid in the polishing barrel, and the polishing liquid has suspended polishing material; and a plurality of curved glass pieces are arranged on the wall of the polishing barrel in the circumferential direction;

[0086] Start the displacement motor to drive the polishing mechanism to move downward through the lifting chain 49, and the polishing ball is in flexible contact with the curved glass piece;

[0087] S3, start the main drive motor 41 to drive all the driven bevel gears 35 in the circumferential direction to rotate through the center shaft 32, the driven bevel gears 35 drive the corresponding shaft A and shaft Ba to rotate, the shaft Ba drives the polishing ball on the upper part of the outer vertical plate to rotate clockwise through the corresponding ball frame 36, and the polishing of the curved glass piece is realized;

[0088] Meanwhile, the rotating shaft Bais also driven to rotate by the sprocket Bay48 and the sprocket C45, the rotating shaft C is driven to rotate by the gear C46 and the gear Bb47, the rotating shaft Bbis driven to rotate the polishing balls in the lower part of the outer vertical plate in the counterclockwise direction by the corresponding ball holder 36, and the polishing of the curved glass piece is realized.

[0089] When the polishing balls are polishing, the polishing balls grind the surface of the curved glass piece by the polishing material, and the polishing material at the position is thrown out by the rotating polishing balls. Since the rotating directions of the polishing balls in the upper part and the lower part of the outer vertical plate are different, the thrown-out polishing material is turned over in the polishing liquid, and is then used by another polishing ball.

[0090] When the polishing balls are polishing, the polishing balls are subjected to the reaction force of the curved glass piece, the reaction force is transmitted to the flexible lifting mechanism 33 through the frame 31, and the flexible lifting mechanism 33 is flexibly connected to the basic frame, so that the polishing balls and the curved glass piece are in flexible contact. In addition, the reaction force of the polishing balls causes the frame 31 to shake. During the shaking of the frame 31, if the polishing balls on one side are away from the curved glass piece, the polishing balls on the other side are close to the curved glass piece, so that a good polishing effect is achieved.

[0091] S4, when the polishing of a certain position of the curved glass piece is completed, the polishing mechanism is driven by the flexible lifting mechanism 33 to continue the up-and-down displacement adjustment, and the polishing of another position of the curved glass piece is carried out……until the polishing is completed.
