Abstract
Description
Technical Field
[0001] This invention relates to the field of polishing equipment technology, and in particular to equipment and methods for polishing curved glass surfaces. Background Technology
[0002] In-vehicle display panels include central control display panels, instrument display panels, head-up displays, electronic rearview mirror displays, and rear-seat entertainment displays.
[0003] In recent years, the automotive display panel market has shown a trend towards larger screens (such as...). Figure 5 As shown, by integrating the central control display panel and instrument display panel into a single unit, a suitable 3D glass panel (also known as 3D curved glass or curved glass component) has emerged. Due to its thinness, fingerprint resistance, anti-glare, and scratch resistance, 3D glass panels can achieve bending and folding of the vehicle's display surface, while maintaining high-quality display even after bending at the edges. This allows for seamless integration of three-dimensional surfaces in uneven dashboard areas and increases the freedom of design and functional integration, further providing human-machine interface functions and entertainment platforms. It has become a major trend in the future development of vehicle panels.
[0004] Current 3D curved glass is formed through mold molding. During the molding process, the first few batches of 3D curved glass produced after the mold is cleaned have good quality (no small dents). However, after a period of production, a small amount of material adheres to the mold during demolding, leading to a decrease in quality (the surface is not smooth enough). Currently, many companies on the market use molded products directly on automobiles without further processing; while this may meet basic requirements, it appears somewhat rough for some high-standard automobiles. Of course, some companies do polish the products before installing them on automobiles.
[0005] Currently, the polishing and grinding of automotive display panels is very simple, using methods similar to those used for polishing metal. This includes methods such as using coarse wax, grinding machines, and coarse yellow sponge discs, either manually or with the aid of very simple mechanical structures. This method is inefficient and lacks quality control, resulting in a less than ideal pass rate.
[0006] To address this, our company has developed an automated polishing equipment for automotive 3D curved glass (abandoning the current rudimentary processing methods) to improve production efficiency and control polishing quality. Summary of the Invention
[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide equipment for polishing curved glass surfaces, which solves the problems of poor polishing effect, low polishing efficiency, low polishing pass rate, and easy damage to curved glass parts.
[0008] It should be noted that current automotive display panels are increasingly adopting integrated 3D curved glass (such as hollow display panels and instrument display panels as one unit), but there is currently no industrial equipment on the market specifically for polishing curved glass. Some simple mechanisms are made by borrowing metal polishing methods, which cannot meet the industrial demand for large-scale, high-efficiency, and stable and controllable quality.
[0009] For example, in existing simple metal polishing mechanisms, a rotating component grinds and polishes a fixed workpiece. During polishing, a chemically corrosive polishing slurry or polishing compound is added. However, the polishing slurry and compound quickly run off, requiring manual collection and filtration before they can be reused. This not only results in low polishing efficiency but also significant waste of the polishing slurry and compound; furthermore, the high cost of these materials increases expenses. Therefore, for cost and efficiency reasons, curved glass components in automobiles are currently avoided as much as possible from polishing and grinding.
[0010] This invention achieves polishing of curved glass parts through low cost, high efficiency, and excellent results. The objective of this invention is achieved through the following technical solutions: (a) In a first aspect, an apparatus for polishing curved glass surfaces is provided, comprising: Adsorption fixture I has multiple adsorption units arranged circumferentially, each unit corresponding to adsorb and fix a curved glass piece; the front of the adsorption unit adsorbs the curved glass piece, and the back has a magnetic back plate and a magnetic contouring part located on the curved part of the curved glass piece. Polishing bucket III has multiple electromagnetic units arranged around its circumference, and is filled with polishing liquid containing suspended magnetic polishing material. Polishing mechanism IV has multiple rotatable polishing balls arranged circumferentially, which are mounted on a flexible lifting mechanism; After the adsorption fixture I circumferentially adsorbs multiple curved glass parts, they are grasped by the gripping mechanism II and sent to the polishing tank III, where the curved glass parts are immersed in the polishing liquid in the polishing tank III, and the magnetic back plate is close to the corresponding electromagnetic unit; when the corresponding electromagnetic unit is energized, the corresponding magnetic back plate and the corresponding magnetic contouring part are magnetized, so that the magnetic polishing material is distributed on the surface of the curved glass parts, and is mainly distributed on the curved part of the curved glass parts. The flexible lifting mechanism lowers the polishing mechanism IV to the center of the polishing barrel III. The polishing mechanism IV drives its circumferential polishing ball to rotate. The polishing ball contacts the surface of the curved glass and is polished by the polishing material. When the polishing mechanism IV is working, it will have a slight sway, which will change the distance between the polishing ball and the surface of the curved glass. In addition, since the polishing mechanism IV can sway slightly on the flexible lifting mechanism during polishing, ...
[0011] In this solution, the polishing material particles contain both physical and chemical polishing components. Preferably, for example, during preparation, physical polishing powder (including magnetically conductive powder) and chemical polishing powder are mixed, then fired into bricks, and finally crushed, appropriately ground, and screened to obtain polishing material with suitable particle sizes. When the polishing material is adsorbed by the electromagnetic unit to grind curved glass parts, the polishing material provides both physical and chemical polishing raw materials. Compared to the traditional method of adding chemical components separately, this solution allows for better control over the chemical polishing components.
[0012] In this solution: by controlling the battery unit, a large amount of polishing material is collected on the curved glass part where polishing is needed, resulting in excellent polishing effect. Furthermore, the polishing material itself has both chemical corrosion and physical abrasion properties, thus combining chemical and physical polishing to further enhance the polishing effect. During polishing, the polishing mechanism IV can slightly oscillate along the flexible lifting mechanism, causing changes in the gap between the polishing ball and the curved glass part. This allows the polishing material and any remaining material after grinding to easily fall off. The remaining material sinks and tumbles in the polishing tank III, where it is reused under magnetic attraction, achieving an automatic polishing material replacement effect. This solution greatly improves the polishing effect, fully utilizes the polishing material, and reduces costs.
[0013] (ii) In conjunction with the first aspect, in the first advantageous extension, the equipment has left and middle workstations, and / or has a right workstation; The central workstation has a central frame; a polishing barrel III is located at the bottom of the central frame; a flexible lifting mechanism is arranged along the central axis of the polishing barrel III; the flexible lifting mechanism includes multiple lifting chains, multiple positioning sprockets E, and multiple positioning sprockets F. The multiple positioning sprockets F are fixed to the inner bottom of the polishing barrel III, and the multiple positioning sprockets E are fixed to the beams of the central frame. The lifting chains pass over the positioning sprockets E and F, which are positioned opposite each other, and their two ends are respectively fixed to the upper and lower positions of the polishing mechanism IV. The corresponding positioning sprockets E are connected to the lifting motor drive; when the lifting motor works, it drives the polishing mechanism IV to move up and down along the central axis of the polishing barrel III. The left workstation has a left frame; a gripping mechanism II is fixed on the left frame; a central base is located at the bottom of the left frame; the adsorption fixture I is lifted by the central base, and the central base can rotate; by rotating the central base, the adsorption fixture I is circumferentially adsorbed and mounted on the curved glass parts; the gripping mechanism II is used to place the adsorption fixture I with the completed parts into the polishing barrel III. Both the adsorption fixture I and the gripping mechanism II have horseshoe notches; when both are located inside the polishing barrel III, the polishing mechanism IV is located at the horseshoe notch; that is, the adsorption fixture I and the gripping mechanism II serve as fixed components during workpiece polishing, and the polishing mechanism IV is located at the horseshoe notch to polish the corresponding curved glass parts. The right workstation has a right-side frame, and its remaining structure and principle are the same as those of the left workstation.
[0014] This advantageous extension mainly provides a preferred positional arrangement for the adsorption fixture I, the gripping mechanism II, the polishing barrel III, and the polishing mechanism IV.
[0015] (III) In conjunction with the first aspect, a second advantageous extension scheme was developed for the polishing barrel III. The polishing barrel III includes a barrel body and electromagnetic units; the barrel body is provided with multiple electromagnetic units along its circumferential direction, forming a column unit with the electromagnetic units in the vertical column position; one column unit corresponds to one curved glass piece; when a certain electromagnetic unit in a column unit is energized, a large amount of polishing material will accumulate on the surface of the curved glass piece at that position.
[0016] In conjunction with the second advantageous extension scheme, an alternative design includes a polishing barrel III. The polishing barrel III has a multi-faceted prism shape, with the intersecting corners of the prism faces recessed inward to form triangular grooves. Each prism face of the barrel has a column unit. Ultrasonic transducers are installed on the groove walls of the triangular grooves, allowing the transducers to be closer to the curved glass surface to remove the remaining material after polishing. Multiple heating tubes are also installed at the bottom of the barrel.
[0017] In conjunction with the second advantageous extension scheme, in one alternative scheme, multiple adjusting cylinders are circumferentially arranged at the top of the polishing barrel III, and the output shaft end of the adjusting cylinder has a rubber roller; when the adsorption fixture I adsorbs the curved glass part and is placed in the polishing barrel III: when the lower end of the adsorption fixture I moves down to the position of the adjusting cylinder, the output shaft of the adjusting cylinder extends, allowing the rubber roller to contact the adsorption unit, guiding the adsorption fixture I to move downward, so that the curved glass part on the inner side of the adsorption fixture I contacts the polishing mechanism IV.
[0018] (iv) In conjunction with the first aspect, a third advantageous extension scheme was designed for the polishing mechanism IV. The polishing mechanism IV includes a frame, a central rotating shaft, and ball holders; the frame is shaped like an inverted barrel, with the central rotating shaft mounted on its upper surface; the central rotating shaft has a driving gear that meshes with multiple driven bevel teeth axially; the driven bevel teeth are mounted on the frame via rotating shaft A; multiple ball holders are also mounted on the frame via corresponding rotating shaft B, and polishing balls are mounted on the ball holders; when rotating shaft B is directly driven connected to rotating shaft A, the polishing balls rotate in the same direction as rotating shaft A; when rotating shaft B is indirectly driven connected to rotating shaft A, the polishing balls rotate in the opposite direction to rotating shaft A. By directly or indirectly driving the corresponding rotating shaft B with the rotating shaft A, the polishing balls at adjacent positions rotate in opposite directions, increasing the complexity of the disturbance within the polishing barrel III. When the polishing balls rotate, they will fling the polishing material from one polishing ball position to another, allowing the polishing material to be fully utilized and preventing it from sinking.
[0019] In conjunction with the third advantageous extension scheme, an alternative scheme was designed for the specific drive of the polishing balls. The frame has multiple vertical unit frames circumferentially. A rotating shaft B is mounted on a vertical unit frame via bearings, and a rotating shaft C is also mounted on the vertical unit frame. The rotating shaft B located at the upper part of the vertical unit frame is called rotating shaft Ba, and the rotating shaft B located at the lower part of the vertical unit frame is called rotating shaft Bb. Rotating shaft A is mounted on the frame via an auxiliary plate and is equipped with a driven bevel gear and a sprocket A. Rotating shaft Ba is fitted with sprockets Bax and Bay, and rotating shaft Bb is fitted with sprocket Bb and gear Bb. Rotating shaft C is equipped with sprocket C and gear C. When the driven bevel gear is connected to sprocket Bb via a chain, gear Bb meshes with gear C, and sprocket C is connected to sprocket Bay via a chain: if shaft A rotates clockwise, then shaft Bb rotates clockwise and shaft Ba rotates counterclockwise; when the driven bevel gear is connected to sprocket Bax via a chain, sprocket Bay is connected to sprocket C via a chain, and gear C meshes with gear Bb: if shaft A rotates clockwise, then shaft Ba rotates clockwise and shaft Ba rotates counterclockwise. That is, when shaft A rotates, it causes adjacent polishing balls in the vertical and circumferential directions to rotate in different directions.
[0020] In this advantageous extended solution, only one central rotating shaft needs to be driven to enable adjacent polishing balls to rotate in different directions, namely clockwise and counterclockwise, allowing the polishing material thrown off by the polishing balls to flow fully within the polishing tank III; under the action of the electromagnetic unit, the polishing material is recycled again. Furthermore, the driving of a single central rotating shaft is also achieved, enabling the polishing of multiple curved glass parts simultaneously.
[0021] (v) In conjunction with the first aspect, the fourth advantageous extension scheme includes the design of adsorption fixture I. Adsorption fixture I comprises a fixture frame and multiple adsorption units; the fixture frame is annular and has a horseshoe notch, and the multiple adsorption units are suspended along the circumference of the fixture frame; The adsorption unit includes a support component, an air connector, and an intermediate component; the air connector is fixed on a tooling frame; the air connector has a central hole, the intermediate component has an insert tube, and the insert tube is vertically inserted into the central hole to form a rotating pair; the intermediate component has an auxiliary pipe, which is connected to the insert tube; the lower end of the intermediate component is hinged to the support component to form a rotating pair, and the axis of the rotating pair is horizontally set. The central hole has channels A and C at different positions on the same radial plane. Channel A is connected to the negative pressure pipeline, and channel C is connected to the positive pressure pipeline. The side wall of the insertion tube has a mating interface. The bearing component has a channel B, and its front side also has a pneumatic suction cup connected to the pipeline B. The pipeline B is connected to the auxiliary channel via a corresponding air tube. When the pneumatic connector and intermediate component rotate together around the insertion tube: if the interface is opposite to channel C, the pneumatic suction cup is on the outside and under positive pressure, and the curved glass component is attached to the pneumatic suction cup; then, if the interface is opposite to channel A, the pneumatic suction cup is on the inside and under negative pressure, and the pneumatic suction cup will adsorb and fix the curved glass component. Corresponding locking and positioning holes are also provided on the intermediate parts and tooling frame. The positions of the two are fixed by positioning bolts to prevent rotation after rotation is completed.
[0022] In conjunction with the fourth advantageous extension scheme, an alternative design includes a support component. The support component comprises a magnetic backplate and a non-magnetic contouring component. The non-magnetic contouring component has a contoured surface on its front side that adapts to the curved glass component. Multiple pneumatic suction cups are provided on the contoured surface, with channels B formed thereon. A through-slot is formed on the non-magnetic contouring component along the front-back direction corresponding to the curved portion of the curved glass component, and a magnetic contouring block is placed within the through-slot. When the pneumatic suction cups are installed on the front side of the non-magnetic contouring component: first, the fixing rod of the pneumatic suction cup is installed; then, a flexible layer is attached to the front side of the non-magnetic contouring component; finally, the rubber disc of the pneumatic suction cup is installed. When the pneumatic suction cup is vacuumed, the rubber disc will pull the curved glass component back, allowing the curved glass component to adhere to the flexible layer.
[0023] This advantageous extension is primarily designed to enable rapid installation of curved glass components. It also facilitates the accumulation of more abrasive material on the curved surfaces of the glass components.
[0024] (vi) In conjunction with the first aspect, the fifth advantageous extension scheme was designed with the gripping mechanism II.
[0025] Specifically, the gripping mechanism II includes a gripping frame, a vertical track frame, and a horizontal track frame. The horizontal track frame is horizontally fixed to the back of the entire equipment, spanning the left, middle, and right workstations. The vertical track frame is slidably mounted on the horizontal track frame, and the gripping frame is slidably mounted on the vertical track frame. The gripping frame can slide vertically on the vertical track frame, and the vertical track frame can slide horizontally on the horizontal track frame. Multiple gripping cylinders are fixed to the gripping frame, with the output shafts of each cylinder facing left, forward, right, and backward, respectively. The adsorption fixture I has multiple insert plates with gripping holes. The gripping frame has a horseshoe notch. When the gripping mechanism II is engaged with the adsorption fixture I, the gripping cylinders extend and insert into the gripping holes of the insert plates. When the multiple gripping cylinders are inserted into the insert plates facing left, forward, right, and backward, the gripping mechanism II and the adsorption fixture I are gripped and fixed.
[0026] In this advantageous extension, the gripping mechanism II achieves a secure and stable gripping of the adsorption fixture I, and this secure structure can be directly used for the installation of the adsorption fixture I during polishing.
[0027] (vii) Based on the first aspect, one or more of the first to fourth advantageous extension schemes can be arbitrarily selected; furthermore, within each advantageous extension scheme, one or more corresponding alternative schemes, or other schemes, can also be arbitrarily selected. That is, the various schemes can be selected and combined to form new schemes. The combination of permutations and combinations will not be elaborated here.
[0028] (viii) Secondly, according to the above scheme, a method for polishing curved glass surfaces is provided, the steps of which are as follows: S1. Place the curved glass component; After the gripping mechanical mechanism II grips the adsorption fixture I, it is placed at the left work position; at this time, the fixture frame (4) is lifted by the central base of the left work position; S1-2. Rotate the adsorption unit on the adsorption fixture I so that the side of the adsorption unit with the pneumatic suction cup faces outwards. At this time, the pneumatic suction cup is in a positive pressure state. Contact the curved glass part with the pneumatic suction cup so that the curved glass part is attached to the adsorption unit. Then rotate the adsorption unit so that the side of the adsorption unit with the pneumatic suction cup faces inwards. At this time, the pneumatic suction cup is in a negative pressure state. The pneumatic suction cup adsorbs and fixes the curved glass part in a negative pressure state. Rotate the adsorption fixture I itself to position the adsorption unit in a position that is easy for a person to install, and then install the curved glass parts on each of the multiple adsorption units one by one; S2, Grab-Fix; S2-1. The gripping frame of the gripping mechanism II fixes the adsorption fixture I, and then the gripping frame moves upward along the vertical track frame; when the lower end of the adsorption fixture I is higher than the polishing barrel III, the vertical track frame moves along the horizontal track frame, so that the adsorption fixture I is directly above the polishing barrel III. S2-2, The gripping frame moves downward along the vertical track frame, so that the adsorption fixture I is coaxially located inside the polishing barrel III; at this time, the gripping mechanism II plays a role in installing and fixing the adsorption fixture I. S3, Polishing mechanism IV moves downward; When the polishing mechanism IV is not in operation, it is raised to the top via a flexible lifting mechanism. The top position is higher than the position of the adsorption fixture I when it is moving horizontally. Under the action of the flexible lifting mechanism, the polishing mechanism IV moves downward; when the polishing mechanism IV descends, it descends through the horseshoe notch of the gripping mechanical mechanism II and the horseshoe notch of the adsorption fixture I, and finally is located at the center of the polishing barrel III; When the polishing mechanism IV descends to the center of the polishing barrel III, the polishing ball contacts the curved glass part on the adsorption fixture I; and the adsorption fixture I is also pressed against the rubber roller of the adjusting cylinder. S4, Polishing; a. Conventional surface treatment; When the electromagnetic unit controlling the polishing barrel III at a certain height is energized, a large amount of magnetic polishing material is gathered on the curved glass piece at that height. Chemical treatment: the aggregated polishing material itself can corrode curved glass parts, thereby performing chemical polishing; during chemical treatment, the temperature conditions of chemical corrosion are controlled by heating tubes; In the physical processing, the aggregated magnetic polishing material is ground on the curved glass part under the squeezing action of polishing mechanism IV. During the physical processing, polishing mechanism IV wobbles slightly on the flexible lifting mechanism, and the contact gap between the polishing ball and the curved glass part changes. Under the action of ultrasonic transducer and polishing ball, the ground material and the polishing material in the original gap will fall off and be thrown out. When the polishing material is thrown out, it surges in polishing barrel III without sinking to the bottom due to the rotation of adjacent polishing balls in different directions. When the ground material is thrown out, it will eventually sink to the bottom after surging for a certain period of time because it is not magnetic. By gradually controlling the energization of electromagnetic units at different heights, the curved glass parts at the corresponding heights are polished in a concentrated manner. b. Unconventional surface treatment; When the corresponding electromagnetic unit is energized, the presence of the magnetically conductive contour block allows the polishing material to be concentrated on the curved surface more effectively than on a conventional surface, thus achieving better polishing of the curved surface. S5. Unload the parts; S5-1. After polishing is completed, polishing mechanism IV rises and gripping mechanism II operates in the opposite manner to step S2, placing adsorption fixture I on the central base of the left station. S5-2. Then rotate the adsorption unit on the adsorption fixture I to make the curved glass part face outward, thereby removing the curved glass part; While performing steps S5-1 and S5-2, the adsorption fixture I at the right station is fed in the same manner as in steps S1 and S2.
[0029] To facilitate understanding, some core design points of the scheme will be explained: First, it enables automated polishing, thus improving work efficiency. In the field of polishing, the polishing methods mainly refer to those used in metal polishing. Two common metal polishing methods are: one involves fixing a single workpiece stationary while rotating mechanical parts grind and polish it (or keeping the mechanical parts stationary while the workpiece rotates), using a chemically corrosive polishing fluid or abrasive; the other involves mixing small parts with abrasive and then adding polishing fluid. The former method requires very strict clearance between the workpiece and the mechanical parts (a major factor affecting polishing results; even a 1-2mm clearance deviation can drastically alter the polishing outcome), making workpiece installation very slow and preventing automated placement and polishing, resulting in very low efficiency. The latter method is only suitable for deburring small parts and cannot polish curved glass surfaces.
[0030] In this scheme, multiple curved glass parts are hoisted circumferentially in one go by adsorption fixture I, and polishing mechanism IV is placed at the center of adsorption fixture I for polishing. The reason why multiple workpieces can be polished at once without significantly affecting the polishing effect is mainly due to: ① The structural design between the gripping mechanism II and the adsorption fixture I ensures that when the gripping mechanism II grips and places the adsorption fixture I into the polishing barrel III, the position of the adsorption fixture I within the polishing barrel III is very precise, and positional deviation is not easily observed; ② The polishing mechanism IV is mounted on a flexible lifting mechanism. During polishing, the polishing mechanism IV will experience slight shaking, causing changes in the gap between the polishing mechanism IV and the workpiece (as mentioned earlier, the gap affects the polishing effect mainly because the gap affects the pressure of the mechanical parts on the workpiece, thus affecting the friction and consequently the polishing). This solution uses the changing gap for polishing (when the polishing mechanism IV shakes, the polishing effect is weak when it is far from the workpiece, and better when it is close to the workpiece; within 1 minute, in traditional polishing methods, the gap has a significant impact on the polishing effect because the mechanical parts are constantly in contact with the workpiece; in this solution, the polishing mechanism IV and the workpiece are in intermittent contact within 1 minute, so the total contact time is shorter than that of traditional polishing methods, and the degree of grinding within 1 minute is not as severe as in traditional methods, thus weakening the impact of the gap).
[0031] In layman's terms, this solution reduces the impact of gaps on the polishing effect per unit time by intermittently contacting the workpiece and polishing mechanism IV. Although the grinding effect of this solution is not as good as the traditional method per unit time, it is not strict about the gap, that is, the gap requirement between the curved glass part and polishing mechanism IV is not strict. It can achieve automated installation and multiple workpieces can be installed at one time (there is no need to worry about gap errors during installation). For enterprises with mass production, it greatly improves production efficiency and is suitable for industrial production.
[0032] Second, the polishing process is more controllable, and the polishing effect is improved. In the field of polishing finishing, the grinding and polishing process is very difficult to control. If any factor fluctuates, it will lead to different polishing results. Sometimes, even the same equipment, the same worker, the same batch of workpieces, and the same batch of polishing materials can produce different polishing results and result in a considerable scrap rate. The reason for this is that there are too many factors affecting the polishing effect, and each factor is too uncontrollable (for example, when adding polishing materials, it cannot be guaranteed that the amount of material remaining in the processing gap after each addition will be consistent; when adding chemical polishing liquid, it cannot be guaranteed that the amount of material remaining in the processing gap after each addition will be consistent; and even slight fluctuations in the amount of material will affect the polishing effect).
[0033] As mentioned in the paragraph "I. Automated polishing improves work efficiency", the traditional polishing method still has the following drawbacks: when polishing, as long as the amount of polishing material or polishing liquid decreases, a certain amount of material is added manually or mechanically intermittently. However, it is difficult to specify the extent to which the material should be added, and it is based on experience. Moreover, due to the excessive number of additions, the amount of material in the gaps fluctuates too much with each addition, which is not conducive to polishing.
[0034] As mentioned in the section "I. Automated polishing and improved work efficiency" in this solution, the impact of gaps on polishing is reduced by intermittently contacting the polishing mechanism IV with the workpiece, thereby better controlling the polishing process.
[0035] In this solution, by controlling the opening and closing of the corresponding electromagnetic units, more polishing material is concentrated at the location that needs to be polished, thereby improving the polishing effect; that is, by controlling the polishing material, the polishing process can be better controlled.
[0036] In this solution, the polishing material contains both physical and chemical components. The electromagnetic unit guides the polishing material, thereby indirectly guiding the chemical components to contact the workpiece. Compared with traditional polishing methods, this solution makes the chemical components more controllable, thus allowing for better control of the polishing process.
[0037] In this design, polishing mechanism IV and the curved glass part are immersed in polishing liquid in polishing tank III. The polishing liquid contains polishing material, and adjacent polishing balls in polishing mechanism IV rotate in opposite directions (clockwise / counterclockwise). An ultrasonic transducer is also included, and polishing mechanism IV can be slightly wiggled to change the gap between itself and the workpiece. During operation: ① The polishing material is guided to a specific area of the curved glass part for polishing via an electromagnetic unit, and polishing is achieved through chemical corrosion. When the polishing mechanism IV approaches the workpiece, the polishing material generates pressure and friction on the workpiece, thus achieving physical polishing. ② During the polishing process, as polishing mechanism IV approaches the workpiece and during polishing, some polishing material and residual material from the workpiece are discarded. This discarded material and residual material tumble within polishing tank III. However, the polishing material can be reused due to magnetic properties, while the residual material sinks. When polishing mechanism IV moves away from the workpiece, the discarded polishing material can be reused, while the residual material in the gap is dislodged by the ultrasonic transducer.
[0038] As can be seen from the above description, in this scheme, the polishing material at the grinding gap is dynamically changing during the grinding process. It is both thrown off and reused, and the excess material is also thrown off but settles. The advantage of this is that it avoids the excess material affecting the workpiece at the grinding gap, thus facilitating control of the polishing process. The above description also shows that the polishing material in this scheme is recycled in polishing barrel III, which makes it easier to control the polishing effect at each stage, such as the polishing degree in the first 10 minutes, the polishing degree in 10-20 minutes, and the polishing degree in 20-30 minutes. This allows for appropriate design of the entire polishing stage (in traditional polishing methods, because polishing material is continuously added, the ratio of new to old abrasive at the gap cannot be precisely controlled, thus hindering the control of the polishing process).
[0039] Third, costs are reduced. As mentioned in "II. The polishing process is more controllable, and the polishing effect is improved," traditional polishing methods involve continuously adding polishing materials and chemical polishing liquids, which are very expensive. This cost-insensitive approach is not conducive to industrial processing and production. Although polishing liquids can be recycled, filtered, and reused, and although they can be settled and reused, the quality of the recycled material is uncontrollable, and the timing of its subsequent use is uncertain. In many cases, it cannot be reused, and even if it is, it is used as a low-quality product.
[0040] In this solution, the polishing material and polishing fluid are already inside polishing tank III and are continuously recycled during the polishing process. The entire polishing process can be designed based on the polishing effect at different time points. Each batch of polishing material and polishing fluid is fully utilized, significantly reducing costs and making it suitable for industrial production.
[0041] The present invention has the following advantages: (1) It can realize automated processing, process multiple workpieces at one time, and significantly improve polishing efficiency, which is suitable for industrial production; (2) It can more accurately control the polishing process and polishing factors, thereby significantly improving the polishing effect through reasonable adjustments; (3) The production cost is reduced, which is suitable for industrial production.

Detailed Implementation
[0043] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0044] (Example 1) Please see Figures 1-5 Equipment for polishing curved glass surfaces, including adsorption fixture I, gripping mechanism II, polishing barrel III, and polishing mechanism IV; Among them, the adsorption fixture I has multiple adsorption units arranged in the circumferential direction, and each unit is corresponding to adsorb and fix a curved glass piece; the front of the adsorption unit adsorbs the curved glass piece, and the back has a magnetic back plate 5 and a magnetic contouring part 6, and the magnetic contouring part 6 is located on the curved part of the curved glass piece. The polishing tank III has multiple electromagnetic units 22 arranged circumferentially on its walls. These units contain polishing fluid with suspended, magnetically conductive polishing material. The polishing material particles themselves contain both physical and chemical polishing components. Preferably, for example, during preparation, physical polishing powder (including magnetically conductive powder) and chemical polishing powder are mixed, then fired into bricks, and finally crushed, appropriately ground, and screened to obtain polishing material with suitable particle sizes. When the electromagnetic units adsorb the polishing material to grind the curved glass part, the polishing material provides both physical and chemical polishing raw materials. Compared to the traditional method of adding chemical components separately, this solution allows for better control over the chemical polishing components.
[0045] Among them, the polishing mechanism IV has multiple rotatable polishing balls arranged in the circumferential direction, which are mounted on the flexible lifting mechanism 33.
[0046] During operation: ① After the adsorption fixture I circumferentially adsorbs multiple curved glass parts, they are grasped by the gripping mechanism II and sent to the polishing tank III, where the curved glass parts are immersed in the polishing liquid in the polishing tank III, and the magnetic back plate 5 is close to the corresponding electromagnetic unit 22; when the corresponding electromagnetic unit 22 is energized, the corresponding magnetic back plate 5 and the corresponding magnetic contouring part 6 are magnetized, so that the magnetic polishing material is distributed on the surface of the curved glass parts, and is mainly distributed on the curved part of the curved glass parts; ② The flexible lifting mechanism 33 drives the polishing mechanism IV to descend to the center of the polishing tank III, and the polishing mechanism IV drives its circumferential polishing ball to rotate, and the polishing ball contacts the surface of the curved glass parts and is polished by the polishing material; when the polishing mechanism IV is working, there will be a slight small amplitude sway, which will change the distance between the polishing ball and the surface of the curved glass parts.
[0047] In the above design: ① Since the polishing mechanism IV is suspended on the soft-lifting mechanism 33, it will slightly shake during operation, resulting in intermittent contact between the polishing mechanism IV and the curved glass piece. Therefore, the gap between the polishing mechanism IV and the curved glass piece has a less significant impact on the polishing degree than in traditional polishing methods (where the gap remains constant for continuous contact). Thus, the gap requirement between the curved glass piece and the polishing mechanism IV is not strict after installation, allowing for the rapid installation of multiple curved glass pieces in a large batch. ② During polishing, by gradually controlling the energization of electromagnetic units at different heights, the polishing of the corresponding height parts of the curved glass piece is concentrated. Furthermore, the electromagnetic units better guide the polishing material to perform physical and chemical polishing of the curved glass piece, allowing for better control of the polishing process. ③ Since the polishing mechanism IV is suspended on the soft-lifting mechanism 33, and the polishing mechanism IV will shake slightly during operation, the gap between the polishing mechanism IV and the curved glass part will change. When the soft-lifting mechanism 33 moves closer to or further away from the curved glass part, the polishing material and the residual material after grinding at the gap will be thrown out. The thrown-out polishing material can be recycled, and the thrown-out residual material sinks down to avoid adverse effects on the grinding at the gap. After the polishing material is thrown out, it can be recycled again. In addition to saving costs, it is also helpful to control the polishing process. For example, what kind of polishing effect should this batch of polishing material achieve after 10-20 minutes of use, and what kind of polishing effect should it achieve after 20-30 minutes of use? Through reasonable design, the polishing process can be better controlled.
[0048] Please see Figure 1 The equipment has left and middle workstations, and / or a right workstation; The central workstation has a central frame; a polishing barrel III is located at the bottom of the central frame; a flexible lifting mechanism 33 is positioned along the central axis of the polishing barrel III; the flexible lifting mechanism 33 includes multiple lifting chains, multiple positioning sprockets E, and multiple positioning sprockets F. The multiple positioning sprockets F are fixed to the inner bottom of the polishing barrel III, and the multiple positioning sprockets E are fixed to the beams of the central frame. The lifting chains pass over the positioning sprockets E and F, which are positioned opposite each other, and their two ends are fixed to the upper and lower positions of the polishing mechanism IV, respectively. The corresponding positioning sprockets E are connected to the lifting motor drive; when the lifting motor is working, it drives the polishing mechanism IV to move up and down along the central axis of the polishing barrel III. The left station has a left frame; a gripping mechanism II is fixed on the left frame; a central base is located at the bottom of the left frame; the adsorption fixture I is lifted by the central base, and the central base can rotate; the curved glass parts are adsorbed and loaded onto the adsorption fixture I in the circumferential direction by rotating the central base; and the adsorption fixture I with the completed parts is placed into the polishing barrel III by the gripping mechanism II. Both the adsorption fixture I and the gripping mechanism II have horseshoe notches; when both are located inside the polishing barrel III, the polishing mechanism IV is located at the horseshoe notches; that is, the adsorption fixture I and the gripping mechanism II serve as fixed components during workpiece polishing, and the polishing mechanism IV is located at the horseshoe notches to polish the corresponding curved glass parts. Right workstation: It has a right-side frame, and the rest of the structure and principle are the same as the left workstation.
[0049] The structure and position design of the left, middle, and right workstations of the equipment are mainly to realize the polishing action of this scheme. During operation, when the workpiece on the left workstation is being polished, the workpiece is installed on the right workstation; when the workpiece on the left workstation is removed and reinstalled, the right workstation performs polishing.
[0050] (Example 2) Based on Example 1, see [link to Example 1] Figures 17-23 The adsorption fixture I was designed. The adsorption fixture I includes a fixture frame 4, which is ring-shaped and has multiple adsorption units suspended around its circumference.
[0051] Specifically, the adsorption unit includes a support component 1, an air inlet connector 2, and an intermediate component 10; For the air connector 2, on its fixed fixture 4; the central part of the air connector 2 has a central hole 2-5 that passes through in the vertical direction; and in the central hole 2-5, channels A2-1 and C2-3 are opened at different positions on the same radial plane; and channel A2-1 is connected to the negative pressure pipeline 2-2, and channel C2-3 is connected to the positive pressure pipeline 2-4. For the intermediate component 10, it has an auxiliary channel and an insertion tube 3 at its upper end; the insertion tube 3 is connected to the auxiliary channel; after the intermediate component 10 inserts the insertion tube 3 into the center hole 2-5 of the air connector 2, the upper end of the insertion tube 3 is locked onto the air connector 2 by a nut, forming a rotating pair structure; a mating interface 3-1 is opened on the side wall of the insertion tube 3, and the mating interface 3-1 is opposite to the channel A2-1 and the channel C2-3. For the bearing component 1, its upper end is hinged to the lower end of the intermediate component 10 to form a rotating pair structure, and the axis of the rotating pair is set horizontally; and the bearing component 1 has a channel B, and its front has a pneumatic suction cup, which is connected to the pipe B; the pipe B is also connected to the auxiliary channel through a corresponding air pipe.
[0052] During operation: Rotating the carrier assembly 1 causes the insertion tube 3 to rotate within the central hole 2-5, aligning the interface 3-1 with the channel A2-1. At this point, the negative pressure pipeline 2-2, channel A2-1, interface 3-1, insertion tube 3, auxiliary channel, channel B, and pneumatic suction cup are connected. Since the negative pressure pipeline 2-2 is always in a negative pressure extraction state, the pneumatic suction cup can be used to adsorb the workpiece. When the carrier assembly 1 is rotated further, aligning the interface 3-1 with the channel C2-3, the positive pressure pipeline 2-4, channel C2-3, interface 3-1, insertion tube 3, auxiliary channel, channel B, and pneumatic suction cup are connected. Since the positive pressure pipeline 2-4 continuously supplies positive pressure air, the pneumatic suction cup can be used to release the workpiece. (That is, by rotating the carrier assembly 1 to different positions, the workpiece can be adsorbed / released.)
[0053] In this embodiment, corresponding threaded holes are provided on the tooling frame 4 and the bearing component 1, and corresponding positioning bolts are inserted into the threaded holes. When it is necessary to rotate the bearing component 1, the bolts are loosened; when it is necessary to fix the position of the bearing component 1 and the tooling frame 4, the bolts are installed for positioning. (This method is relatively simple, but positioning and locking can also be achieved by electric telescopic pins or other locking methods; however, as long as the "locking and positioning" concept of this solution is involved, it is within the protection scope of this solution.)
[0054] In this embodiment, the support component 1 is designed. The support component 1 includes a magnetic back plate 5, a non-magnetic contouring component 6, and a magnetic contouring block 7. The non-magnetic contouring component 6 is fixedly locked to the front side of the magnetic back plate 5, and the front side of the non-magnetic contouring component 6 is a contouring surface that fits the curved glass component. The non-magnetic contouring component 6 has a through-hole groove at the bending surface of the corresponding curved glass component, and the magnetic contouring block 7 is placed in the through-hole groove. The magnetic contouring block 7 is also locked and fixed to the magnetic back plate 5. The front side of the magnetic contouring block 7 is a contouring surface that fits the bending surface of the curved glass component. It should be noted that corresponding pneumatic suction cups can be provided on both the non-magnetic contouring component 6 and the magnetic contouring component 7, and corresponding channels can be provided on both, from which the pipes of the pneumatic suction cups are led out.
[0055] Since the front of the magnetic backplate 5 has a non-magnetic contour piece 7, and the front of the non-magnetic contour piece 7 is on a curved glass piece, when the electromagnetic unit 22 is energized, the magnetic backplate 5 will be magnetized, causing a large amount of magnetic polishing material to accumulate on the front of the curved glass piece, thereby improving the polishing effect. In addition, since the non-magnetic contour piece 7 also has a magnetic contour block 7 (which will also be magnetized by the energized electromagnetic unit 22), and the magnetic contour block 7 is located at the curved surface of the curved glass piece, a large amount of magnetic polishing material will accumulate at the curved surface of the curved glass piece, thus enabling focused polishing.
[0056] Furthermore, the pneumatic suction cup was designed accordingly. When the pneumatic suction cup is installed on the front of the non-magnetic contouring part 7: first, the fixing rod of the pneumatic suction cup is installed; then, a flexible layer is attached to the front of the non-magnetic contouring part 6; and finally, the rubber disc of the pneumatic suction cup is installed. The purpose of the flexible layer is to allow the back of the curved glass part (the non-polishing surface) to adhere to the flexible layer, preventing magnetic polishing material from accumulating on the back of the curved glass part. When the pneumatic suction cup is vacuumed, the rubber disc will retract and adhere to the curved glass part, allowing the curved glass part to fully adhere to the flexible layer, thus preventing magnetorheological polishing material from accumulating on the surface of the curved glass part that is being suctioned.
[0057] (Example 3) Based on Examples 1 and 2, and referring to Figures 24-28 The mechanical gripping structure II was designed.
[0058] Specifically, it includes a horizontal track frame 14, a vertical track frame 13, and a gripping frame 11; the horizontal track frame 14 is located at the back of the equipment and spans the left, middle, and right workstations; the vertical track frame 13 is mounted on the horizontal track frame 14, and the gripping frame 11 is mounted on the vertical track frame 13; the vertical track frame 13 can slide left and right on the horizontal track frame 14, and the gripping frame 11 can slide vertically on the vertical track frame 13; Furthermore, the gripping frame 11 is equipped with multiple gripping cylinders 12 in different directions, and multiple flat openings 15 are provided on the gripping frame 11; moreover, the adsorption fixture I has multiple insert plates 8, and gripping holes 9 are provided on the insert plates 8.
[0059] Preferably, there are four gripping cylinders 12, with their output shafts extending to the left, forward, right, and backward, respectively.
[0060] When the mechanical gripping structure II is in contact with the adsorption fixture I: the insert plate 8 is passed through the flat opening 15, and then the output shaft of the gripping cylinder 12 extends and is inserted into the gripping hole 9 of the insert plate 8, thus realizing the gripping of the adsorption fixture I by the gripping frame 11. During gripping, the gripping cylinder 12 effectively limits the adsorption fixture I from four directions: front, back, left, and rear, thereby achieving gripping and fixing.
[0061] The aforementioned gripping method is more stable than mechanical gripping, preventing curved glass pieces from falling during transport. Furthermore, the gripping frame 11 only performs two simple movements during the gripping action and the subsequent transport action: vertical and horizontal. (Compared to auxiliary robotic arm structures with complex movements, this solution avoids excessive or unstable movements that could cause curved glass pieces to fall.)
[0062] In this embodiment, the gripping frame 11 is horseshoe-shaped, as is the tooling frame 4. After the gripping frame 11 grips the adsorption tool I, it places the adsorption tool I, which is suspended with multiple curved glass pieces, onto the polishing mechanism. The polishing mechanism is positioned at the horseshoe notch of the gripping frame 11 and the tooling frame 4, thus placing the polishing equipment at the center of the adsorption tool I. The gripping frame 11 remains in place, serving to fix the adsorption tool I during the polishing process. When the polishing mechanism is working, it can adsorb multiple curved glass pieces on the tool I for polishing at once. After polishing is completed, the gripping frame 11 lifts the adsorption tool I back to the initial position where the curved glass was adsorbed. After the curved glass has been polished, a new curved glass piece is then installed.
[0063] When the mechanical gripping structure II is in operation: ① With the suction fixture I in its initial position, loosen the bolts between the fixture frame 4 and the load-bearing component 1 on the fixture unit (or tighten them using a starting pin, etc.), rotate the load-bearing component 1 so that the side with the pneumatic suction cup is on the outside (during rotation, the pneumatic suction cup is connected to the positive pressure pipeline 2-4 via the insertion tube 3 and the channel C2-3, and the pneumatic suction cup does not generate suction force); ② Place the curved glass part to be processed onto the pneumatic suction cup, and then rotate the curved glass and the load-bearing component 1 together. Turn the surface of the bearing component 1 with the pneumatic suction cup to the inside (equivalent to the curved glass piece being located on the inside); at this time, the pneumatic suction cup is connected to the negative pressure pipeline 2-2 through the insertion tube 3 and the channel A2-1, and the pneumatic suction cup generates negative pressure adsorption force to adsorb and fix the curved glass piece; ③ Move the gripping frame 11 to directly above the adsorption fixture I through the horizontal track frame 14, and then drive the gripping frame 11 to move downward through the vertical track frame 13. When the gripping frame 11 is close to the fixture frame 4 of the adsorption fixture I, the insertion plate 8 is inserted into the flat opening 15 and inserted... The upper end of plate 8 protrudes from the flat opening 15; then the output shaft of the gripping cylinder 12 extends and enters the gripping hole 9 at the upper end of the insert plate 8 (i.e., the gripping action is achieved); ④ Then the entire adsorption fixture I is lifted upward by the vertical track frame 13, and then the adsorption fixture I is transported to the polishing mechanism by the horizontal track frame 14, and the polishing mechanism is positioned at the horseshoe notch of the fixture frame 4 and the gripping frame 11, that is, the polishing mechanism is located at the central axis position of the adsorption fixture I (i.e., the transport action is achieved); ⑤ Then the adsorption fixture is moved by the vertical track frame 13. Ⅰ. Move downwards, allowing the adsorption fixture Ⅰ to descend to the polishing component of the polishing mechanism. As the polishing mechanism rotates, it polishes all the curved glass pieces hoisted circumferentially by the adsorption fixture Ⅰ through the polishing component (during the polishing process, the gripping frame 11 does not release the adsorption fixture Ⅰ, thus fixing the adsorption fixture Ⅰ); ⑥ After polishing is completed, the gripping frame 11 transports the adsorption fixture Ⅰ back to the initial work position, then loosens the bolts, rotates the bearing assembly 1, and removes the polished curved glass pieces; then, the unprocessed curved glass pieces are installed.
[0064] (Example 4) Please see Figure 8 and Figure 9 Based on Example 1, the structure of polishing barrel III is disclosed. Specifically, polishing barrel III includes barrel body 21 and electromagnetic units 22; multiple electromagnetic units 22 are provided on the outer wall of barrel body 21, and polishing liquid and polishing material are also contained inside barrel body 21.
[0065] In this embodiment, the barrel 21 is in the shape of a multi-faceted prism, and there is a row of electromagnetic units 22 on the outer wall of each prism of the barrel 21. When the adsorption fixture I adsorbs the curved glass piece and places it in the polishing barrel III, there is a curved glass piece corresponding to the inner wall of each prism; and the magnetic back plate 5 is close to the wall of the barrel 21, and the front of the curved glass piece faces the center of the barrel 21.
[0066] Furthermore, multiple annular strips 23 are fitted from top to bottom on the outer wall of the cylinder 21, and the electromagnetic unit 22 is fixed on the corresponding annular strip 23.
[0067] In this embodiment, the wall of the barrel 21 is recessed inward to form a triangular groove on both sides corresponding to the curved glass workpiece; the outer wall of the triangular groove is provided with multiple ultrasonic transducers 23. When the polishing mechanism polishes, the ultrasonic transducers 23 remove the polishing residue.
[0068] In this embodiment, a heating tube 24 is also provided at the bottom of the inner part of the barrel 21 to control the temperature of the polishing liquid.
[0069] When the polishing mechanism polishes a part of the curved glass piece: the electromagnetic unit 22 at the corresponding position is turned on, and the electromagnetic unit 22 makes the magnetic back plate magnetic, thereby attracting a large amount of polishing material to the corresponding part of the curved glass piece.
[0070] In this embodiment, multiple adjusting cylinders 26 are circumferentially arranged at the top of the polishing barrel III, and the output shaft end of the adjusting cylinder 26 has a rubber roller. When the adsorption fixture I adsorbs the curved glass part and is placed in the polishing barrel III: when the lower end of the adsorption fixture I moves down to the position of the adjusting cylinder 26, the output shaft of the adjusting cylinder 26 extends, allowing the rubber roller to contact the adsorption unit, guiding the adsorption fixture I to move downward, so that the curved glass part on the inner side of the adsorption fixture I contacts the polishing mechanism IV. Furthermore, when the adsorption fixture I adsorbs the curved glass part and is placed in the polishing barrel III, the rubber roller at the output shaft end of the adjusting cylinder 26 abuts against the magnetic back plate 5.
[0071] (Example 5) refer to Figures 10-16Based on Example 1, the polishing mechanism IV was designed. Polishing mechanism IV includes a frame 31, polishing balls, and a flexible lifting mechanism 33. The frame 31 is barrel-shaped, with multiple polishing balls arranged on its circumferential cylindrical surfaces. All polishing balls are driven to rotate via the same central shaft 32, with adjacent polishing balls rotating in opposite directions. The flexible lifting mechanism 33 is suspended on the frame. The lower end of the flexible lifting mechanism 33 is flexibly connected to the inner bottom of the polishing barrel, and its upper end is mounted on the upper frame of the basic frame. Furthermore, the polishing barrel contains polishing liquid with suspended polishing material; multiple curved glass pieces are circumferentially placed on the inner wall of the polishing barrel.
[0072] During operation: The flexible lifting mechanism 33 drives the frame 31 to descend, allowing the polishing ball on the frame 31 to contact the curved glass parts. Then, the central rotating shaft 32 drives the polishing ball to rotate, polishing all the curved glass parts around the running light barrel together, resulting in high running light efficiency (metal parts are usually harder, so the polishing approach is to polish them piece by piece, which is less efficient). During the polishing process, the polishing balls remove rough residue from the surface of the curved glass part through the polishing material in the polishing fluid. When the polishing balls rotate, they also fling these polishing materials. Since the directions of each polishing ball are not the same, the flung polishing material will roll in the polishing fluid, allowing the polishing material to be used by other polishing balls. The polishing material is fully utilized and avoids sinking. During the polishing process, the curved glass surface exerts a reaction force on the polishing balls, causing the frame 21 to sway on the flexible lifting mechanism 33 (in simpler terms, the frame 21 oscillates / shakes on the flexible lifting mechanism 33). Consequently, some polishing balls move away from the curved glass surface, while others move closer. When closer, they provide a grinding effect; when farther away, they allow the polished residue to settle naturally. (Currently, in the polishing field, when further polishing metal, the polishing balls are either fixed using a rigid mechanism or a flexible mechanism. However, since the polishing balls are always in contact with the workpiece, the polished residue accumulates on the workpiece surface, affecting subsequent polishing.) In this embodiment, Figures 10-14As shown, the installation of the central rotating shaft 32 is designed as follows. A sleeve 40 is fixed on the frame 31, and a 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. A drive gear 34 is installed at the extended end of the central rotating shaft 32. The drive gear 34 has multiple driven bevel teeth 35 circumferentially meshing with it. The driven bevel teeth 35 are mounted on the frame 31 via a rotating shaft A. Furthermore, a ball holder is mounted on the frame 31 via a rotating shaft B, and polishing balls are mounted on the ball holder. When the rotating shaft B of some polishing balls is directly connected to the rotating shaft A, the rotation direction of these polishing balls is the same as that of the rotating shaft A. When the rotating shaft B of some polishing balls is connected to the rotating shaft A via a rotating shaft C, the rotation direction of the polishing balls is opposite to that of the rotating shaft A.
[0073] When the central rotating shaft 32 rotates, it can drive all the driven bevel teeth 35 to rotate together, and then drive the corresponding polishing balls to rotate clockwise or counterclockwise through the driven bevel teeth 35.
[0074] In this embodiment, reference Figures 11-14 The frame 31 was designed. The frame 31 includes an upper ring frame 37, a lower ring frame 38, and a vertical unit frame 39. The upper ring frame 37 and the lower ring frame 38 are placed parallel to each other vertically, and are supported and fixed in the circumferential direction by multiple vertical unit frames 39. The polishing ball is then mounted on the vertical unit frame 39 through a ball holder 36.
[0075] In addition, a sleeve 40 is fixed on the upper ring frame 37, and a central rotating shaft 32 is installed inside the sleeve 40; the upper end of the central rotating shaft 32 is driven by the main drive motor 41, and its lower end extends out from the sleeve 40. Furthermore, the rotating shaft A is installed on the lower surface of the upper ring frame 37 via the auxiliary plate 50; the two rotating shafts B are respectively installed on the upper and lower parts of the vertical unit frame 39, and the rotating shafts B on the upper and lower parts are referred to as rotating shaft Ba and rotating shaft Bb; the rotating shaft C is also installed on the vertical unit frame 39.
[0076] The structure of the entire frame 31 is very simple. After design and production, it is lightweight, which facilitates the vertical movement of the frame 31 under the drive of the flexible lifting mechanism 33.
[0077] In this embodiment, reference Figure 13 and Figure 14The vertical unit frame 39 was designed. The vertical unit frame 39 includes an inner vertical plate 42, an outer vertical plate 43, and a horizontal support plate 44. The inner vertical plate 42 and the outer vertical plate 43 are placed vertically, parallel to each other at their inner and outer sides respectively. Their upper and lower ends are fixedly connected by corresponding horizontal support plates 44, which are then bolted to the upper ring frame 37 and the lower ring frame 38. Rotating shafts B are installed at the upper and lower positions of the vertical unit frame 39, respectively referred to as rotating shaft Ba and rotating shaft Bb. Polishing balls are mounted on the ends of rotating shafts Ba and Bb via corresponding ball holders 36; these polishing balls are referred to as the upper polishing ball and the lower polishing ball, respectively.
[0078] The structure of this vertical unit frame 39 is very simple, facilitating direct fixing and installation with the upper ring component and the lower ring frame 38. During operation: If shaft A directly drives shaft Bb to rotate, and then shaft Bb is connected to shaft Ba via shaft C, then when shaft A rotates clockwise, shaft Bb will rotate clockwise and shaft Ba will rotate counterclockwise. If shaft A directly drives shaft Ba to rotate, and then shaft Ba is connected to shaft Bb via shaft C, then when shaft A rotates clockwise, shaft Ba will rotate clockwise and shaft Bb will rotate counterclockwise.
[0079] In this embodiment, reference Figure 14 The specific drive mechanisms for rotating shafts A and B were designed. Rotating shaft A is equipped with a driven bevel gear 35 and a sprocket A51; rotating shaft C is equipped with a sprocket C45 and a gear C46; rotating shaft Ba is equipped with a sprocket Bax and a sprocket Bay38; and rotating shaft Bb is equipped with a sprocket Bb52 and a gear Bb47.
[0080] When the driven bevel gear 35 is connected to sprocket Bb52 via a chain, gear Bb47 meshes with gear C46, and sprocket C45 is connected to sprocket Bay38 via a chain: if shaft A rotates clockwise, then shaft Bb rotates clockwise and shaft Ba rotates counterclockwise; when the driven bevel gear 35 is connected to sprocket Bax via a chain, sprocket Bay38 is connected to sprocket C45 via a chain, and gear C46 meshes with gear Bb47: if shaft A rotates clockwise, then shaft Ba rotates clockwise and shaft Ba rotates counterclockwise. That is, when shaft A rotates, it causes adjacent polishing balls in the vertical and circumferential directions to rotate in different directions.
[0081] The drive structure formed by the central rotating shaft 32, the driving gear 34, the driven bevel gear, and the rotating shafts A and B is relatively simple in structure, but it achieves a relatively complex function. That is, the central rotating shaft 32 enables different polishing balls to rotate in different directions, thereby enabling the polishing balls to drive the polishing material to flip and prevent the polishing material from sinking.
[0082] Of course, the above-mentioned drive structure is only a preferred method. Other polishing ball rotation methods can be designed using similar ideas. For example, the rotation directions of adjacent polishing balls on the top and bottom may be different, while the rotation directions of adjacent polishing balls on the circumferential side may be the same. This can be achieved by slightly changing the connection method of the sprocket and the corresponding gear. However, all such ideas are within the protection scope of this solution.
[0083] In this embodiment, reference Figures 6-8 , Figure 10 A flexible lifting mechanism 33 was designed. The flexible lifting mechanism 33 includes multiple lifting chains 49 and multiple positioning sprockets. One end of each lifting chain 49 is fixed to the upper surface of the frame 31, and the other end wraps around the upper positioning sprocket E, then wraps back around the lower positioning sprocket F, and finally connects to the lower surface of the frame 31. The upper positioning sprocket is connected to a lifting motor, which drives the frame 31 to move up and down via the lifting chains 49. When the polishing ball is polishing, the frame 31 is mounted on the flexible lifting mechanism 33, and the polishing ball makes flexible contact with the curved glass component.
[0084] In addition to driving the frame 31 to move up and down, the flexible lifting mechanism 33 also enables the polishing ball to make flexible contact with the curved glass part. During the polishing process, the frame 31 can make a small sway in the flexible lifting mechanism 33, so that the polishing ball sometimes contacts the curved glass part for polishing and sometimes separates from the curved glass part to facilitate the removal of the remaining material after polishing, thus achieving better polishing.
[0085] (Example 6) Based on Example 1, and combined with Examples 2 to 5, Example 6 is formed.
[0086] (Example 7) Based on Example 6, a method for polishing curved glass surfaces is disclosed, the processing steps of which are as follows: S1. Place the curved glass component; After the gripping mechanism II of S1-1 grips the adsorption fixture I, it is placed at the left work position; at this time, the fixture frame 4 is lifted by the central base of the left work position. S1-2. Rotate the adsorption unit on the adsorption fixture I so that the side of the adsorption unit with the pneumatic suction cup faces outwards. At this time, the pneumatic suction cup is in a positive pressure state. Contact the curved glass part with the pneumatic suction cup so that the curved glass part is attached to the adsorption unit. Then rotate the adsorption unit so that the side of the adsorption unit with the pneumatic suction cup faces inwards. At this time, the pneumatic suction cup is in a negative pressure state. The pneumatic suction cup adsorbs and fixes the curved glass part in a negative pressure state.

S3, Polishing mechanism IV moves downward; When the polishing mechanism IV is not in operation, it is lifted to the top by the flexible lifting mechanism 33. The top position is higher than the position of the adsorption fixture I when it is moving horizontally. Under the action of the flexible lifting mechanism 33, the polishing mechanism IV moves downward; when the polishing mechanism IV descends, it descends through the horseshoe notch of the gripping mechanical mechanism II and the horseshoe notch of the adsorption fixture I, and finally is located at the center of the polishing barrel III; When the polishing mechanism IV descends to the center of the polishing barrel III, the polishing ball contacts the curved glass part on the adsorption fixture I; and the adsorption fixture I is also pressed against the rubber roller of the adjusting cylinder 26. S4, Polishing; a. Conventional surface treatment; When the electromagnetic unit 22 controlling the polishing barrel III at a certain height is energized, a large amount of magnetic polishing material is gathered on the curved glass piece at that height. Chemical treatment: the aggregated polishing material itself can corrode the curved glass parts, thereby performing chemical polishing; during chemical treatment, the temperature conditions of chemical corrosion are controlled by heating tube 25; The physical processing involves grinding the curved glass part under the extrusion of the polishing mechanism IV with the aggregated magnetic polishing material; and during the physical processing, each adjacent polishing ball rotates in a different direction. During physical processing, the polishing mechanism IV oscillates slightly on the flexible lifting mechanism 33, and the contact gap between the polishing ball and the curved glass part changes. Under the action of the ultrasonic transducer 24 and the polishing ball, the material that is ground off and the polishing material in the original gap will fall off and be thrown out. When the polishing material is thrown out, it surges in the polishing barrel III without sinking to the bottom under the action of the adjacent polishing balls rotating in different directions. When the ground off material is thrown out, it will eventually sink to the bottom after surging for a certain period of time because it is not magnetic. By gradually controlling the energization of electromagnetic units 22 at different heights, the curved glass parts at the corresponding heights are polished in a concentrated manner. b. Unconventional surface treatment; When the corresponding electromagnetic unit 22 is energized, the presence of the magnetically conductive contour block 7 allows the polishing material to be concentrated on the curved surface more effectively than on a conventional surface, thus achieving better polishing of the curved surface.
