Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a circular glass grading polishing device. Background Technology

[0002] Glass polishing equipment is a specialized machine used to improve the surface smoothness, flatness, and light transmittance of glass products. It mainly serves the fields of construction, automobiles, electronic displays (such as mobile phone cover plates and screens), optical lenses, and home decoration. This type of equipment is usually designed for flat glass. Through the process of fine grinding and polishing, it uses abrasives of different particle sizes (such as diamond and cerium oxide) in conjunction with polishing discs (commonly made of polyurethane or felt) to effectively remove scratches, bumps, and matte layers from the glass surface under precisely controlled pressure, speed, and cooling conditions.

[0003] Glass polishing equipment can significantly improve the optical performance, aesthetics, and tactile quality of glass, but it still has certain problems: 1) Traditional equipment requires manual transfer of glass or segmented processing at independent workstations, resulting in wasted time during process transitions and excessively long polishing times for both sides of the glass; 2) Existing equipment has fixed suction cup positions, which cannot adapt to multiple sizes of round glass, requiring machine stoppage for adjustment when switching sizes; 3) Manual flipping causes positional deviations on both sides, and uneven pressure on the polishing head leads to surface quality fluctuations; 4) Polishing slurry splashes pollute the equipment and the environment, and residual slurry adhesion reduces the quality of subsequent polishing. Therefore, in view of the above situation, there is an urgent need to develop a graded polishing equipment for round glass to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a circular glass grading and polishing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circular glass grading and polishing device, comprising:

[0006] The processing table has multiple collection slots on both sides and an air blowing pipe installed on the outer wall.

[0007] The circular conveying mechanism includes a circular track and multiple sets of conveying components distributed along the track; the conveying components include a slide, a connector, a support frame and suction cups, the support frame is fixed to the slide through the connector, the slide is slidably connected to the circular track, the support frame is provided with a groove, and multiple suction cups are adjustablely installed in the groove;

[0008] The top plate and top frame are placed sequentially on the processing table;

[0009] The graded polishing mechanism includes a drive assembly, a transmission assembly, and multiple polishing assemblies;

[0010] Drive assembly: located on the top frame, including motor c and cylinder a, with a drive wheel at the output end of motor c;

[0011] The transmission assembly includes a suspension, a guide rod a, a guide sleeve a, a drive shaft, a synchronous pulley a, and a synchronous belt a; the suspension is movably mounted on the top frame, the guide rod a is vertically fixed to the suspension and slides through the guide sleeve a, the guide sleeve a passes through the top frame, and the piston rod of the cylinder a is connected to the suspension; the drive shaft is rotatably mounted on the suspension, the synchronous pulley a is sleeved on the drive shaft, and the drive shaft is driven by the synchronous pulley a and the synchronous belt a;

[0012] The polishing assembly includes a mounting frame, a slide rail slider module a, a follower, a motor a, a tensioning wheel, a motor b, and a synchronous belt b. The mounting frame is fixed to the bottom end of the drive shaft. The follower is slidably mounted in the mounting frame via the slide rail slider module a. The motor a is horizontally mounted in the mounting frame. A lead screw is installed at the output end of the motor a, and the motor a drives the lead screw to control the displacement of the follower. A rotating shaft is vertically inserted through one side of the follower. A polishing head is detachably mounted at the bottom end of the rotating shaft. A synchronous wheel b is fitted at the top end of the rotating shaft. The tensioning wheel and the motor b are mounted on the outer wall of the mounting frame. A synchronous wheel c is installed at the output end of the motor b. The synchronous wheels b, c, and tensioning wheel are connected by a synchronous belt b.

[0013] A clamping and flipping mechanism, located on one side of the processing table, includes:

[0014] Lifting assembly: includes cylinder b, lifting frame, guide rod b and guide sleeve b. Cylinder b is fixed on the top frame, the lifting frame is movably set at the bottom of the top frame, and guide sleeve b passes through the top frame. Cylinder b drives the lifting frame to rise and fall along the guide sleeve b.

[0015] Clamping assembly: includes two follower frames symmetrically slidably mounted on the lifting frame, and a lead screw mechanism that drives the follower frames to move in opposite directions;

[0016] The flipping assembly includes a clamping component that is rotatably mounted on the follower frame and a linkage transmission mechanism that synchronously drives the clamping component to rotate.

[0017] Specifically, the ring conveyor mechanism uses multiple adjustable suction cup conveying components to adapt to and continuously transport round glass of different sizes. In the graded polishing mechanism, each polishing component is equipped with polishing heads of different mesh sizes, corresponding to multiple collection tank stations on both sides of the processing table. Motor a drives the lead screw to control the follower to move radially along the slide rail slider module a, adjusting the polishing head to adapt to changes in glass size. Motor b drives the polishing head to rotate at high speed to perform polishing. At the same time, the ring track transports the glass sequentially to polishing stations of different mesh sizes to complete the graded processing. Combined with the clamping and flipping mechanism, the glass is automatically flipped on both sides. Combined with the residual liquid removal of the air blowing pipe and the waste liquid recycling of the collection tank, the automation level and surface quality consistency of the multi-stage polishing of round glass are significantly improved.

[0018] Preferably, the processing table is viewed from above as a racetrack shape, with six collection slots symmetrically arranged on both sides, and the air blowing pipe is inclined towards the conveying path; the support frame is X-shaped, the slides are radially distributed, and there are five suction cups, with one fixed at the center.

[0019] Specifically, the six collection tanks symmetrically arranged on the racetrack-shaped processing table precisely correspond to the workstations of six polishing heads with different mesh sizes, forming a highly efficient graded polishing production line. The inclined air pipes use directional airflow to remove residual liquid from the glass surface and guide it into the collection tanks. Combined with the radial slides of the X-shaped support frame and the five-point adaptive system formed by the central fixed suction cup and the four-way adjustable suction cup, the circular glass is firmly clamped and the positioning accuracy of the center is ensured, which significantly improves the efficiency and surface quality consistency of double-sided graded polishing of multi-size glass.

[0020] Preferably, there are six drive shafts and six sets of polishing components; the number of conveying components of the annular conveyor mechanism is eight, of which six sets correspond to the polishing station, one set corresponds to the clamping and flipping station, and one set corresponds to the loading and unloading station.

[0021] Specifically, six drive shafts and six polishing components precisely correspond to six polishing stations, forming a complete graded polishing sequence. Each station is equipped with polishing heads of different mesh sizes to achieve progressive fine finishing of the glass surface. Among the eight conveying components, six simultaneously carry the glass for multi-stage polishing, one is dedicated to the clamping and flipping station to achieve automatic double-sided flipping of the glass, and one is responsible for the loading and unloading stations to ensure continuous material supply. The three work together to form a fully closed-loop automated production line, eliminating waiting time between processes, improving equipment utilization, and avoiding positioning errors caused by manual intervention.

[0022] Preferably, a slide rail slider module b is installed between the follower frame and the lifting frame. The follower frame is slidably connected to the lifting frame through the slide rail slider module b. The screw mechanism includes a bidirectional screw and a motor d. The bidirectional screw is rotatably mounted on the lifting frame. The motor d is horizontally fixed on the lifting frame. The bidirectional screw and the motor d are driven and connected by a sprocket and chain. The two ends of the bidirectional screw are distributed and pass through two sets of follower frames. The follower frame is equipped with a threaded pair adapted to the bidirectional screw.

[0023] Specifically, the slide rail slider module b provides high-precision linear guidance for the follower frame. Combined with the bidirectional lead screw driven by the motor d through the sprocket and chain, it forces the two follower frames to open and close synchronously and symmetrically along the slide rail slider module b, eliminating center offset when clamping glass and ensuring that the center of the round glass of different sizes is always aligned with the flipping axis. At the same time, the sprocket and chain drive effectively overcomes the torsional deformation of the long-axis bidirectional lead screw, ensuring bidirectional balance of clamping force for large-size glass, avoiding the risk of micro-cracks caused by uneven pressure on the glass surface, and improving flipping stability and safety.

[0024] Preferably, the linkage transmission mechanism includes: a synchronous pulley d coaxially fixed to the clamping member, a motor e mounted on the outer wall of the lifting frame, a synchronous shaft driven by the motor e, a synchronous pulley e slidably sleeved on the synchronous shaft, and a synchronous belt c connecting the synchronous pulley d and the synchronous pulley e.

[0025] Specifically, a dynamic linkage core is formed by the synchronous wheel e, which is slidably sleeved through the synchronous shaft. When the motor e drives the synchronous shaft to rotate, the keyway structure forces the synchronous wheel e to rotate synchronously in the circumference. Then, the power is precisely transmitted to the synchronous wheel d through the synchronous belt c, which drives the clamping parts on both sides to achieve absolute synchronous flipping. The sliding sleeve design allows the synchronous wheel e to move freely along the synchronous shaft axis, perfectly adapting to the positional changes when the clamping components adjust the spacing of the follower frame. This ensures that the flipping action of large-size glass is always free from transmission interference, eliminates the flipping angle deviation caused by glass size switching, and ensures the consistency of the double-sided polishing position.

[0026] Preferably, the synchronizing pulley e is rotatably connected to the follower frame, a key is installed on the synchronizing shaft, and a matching keyway is provided on the inner wall of the synchronizing pulley e.

[0027] Specifically, the rigid meshing of the key and keyway forces the synchronizing wheel e to be absolutely synchronized with the circumferential direction of the synchronizing shaft, completely eliminating the risk of transmission slippage and ensuring precise power transmission of the motor e; at the same time, the synchronizing wheel e is rotatably connected to the follower frame through an independent bearing, allowing the keyway to slide freely along the axial direction of the synchronizing shaft, perfectly adapting to the axial displacement when the clamping assembly adjusts the spacing of the follower frame while ensuring zero torque loss transmission.

[0028] Preferably, side baffles are installed on both sides of the processing table to prevent polishing liquid from splashing.

[0029] It should be noted here that, Figure 4 , Figure 13 In this context, A represents the circular glass to be polished.

[0030] Compared with the prior art, this utility model provides a circular glass grading and polishing device, which has the following beneficial effects:

[0031] A fully closed-loop, graded polishing production line is constructed using six sets of polishing heads with different mesh sizes and six collection tank stations. Combined with eight sets of conveying components, it achieves automatic glass transfer. The six-station polishing + flipping + loading and unloading completely eliminates waste time in process connections, significantly improving efficiency. The innovative use of an X-shaped support frame radial slide and a five-point suction cup system, combined with radial adaptive adjustment of the polishing head, firmly clamps full-size glass with a center positioning deviation of ≤0.2mm. With the addition of a 30° inclined air pipe for directional removal of residual liquid and a modular quick-change polishing head design, it breaks through existing efficiency bottlenecks while achieving a dual technological improvement of high yield and low pollution recovery rate.

[0062] The flipping assembly 730 includes a clamping member 731 rotatably mounted on the follower frame 722 and a linkage transmission mechanism that synchronously drives the clamping member 731 to rotate.

[0063] Specifically, the annular conveying mechanism 20 uses multiple adjustable suction cups 224 to transport components 220, which are adapted to and continuously transport circular glass of different sizes. In the graded polishing mechanism 60, each polishing component 620 is equipped with polishing heads 6232 of different mesh sizes, corresponding to multiple collection tanks 110 stations on both sides of the processing table 10. The motor a624 drives the lead screw 6241 to control the follower 623 to move radially along the slide rail slider module a622, adjusting the polishing head 6232 to adapt to changes in glass size. The motor b626 drives the polishing head 6232 to rotate at high speed to perform polishing. At the same time, the annular track 210 transports the glass to polishing stations of different mesh sizes in sequence to complete the graded processing. With the help of the clamping and flipping mechanism 70, the glass is automatically flipped on both sides. Combined with the residual liquid removal of the air pipe 120 and the waste liquid recycling of the collection tank 110, the automation level and surface quality consistency of the multi-stage polishing of circular glass are significantly improved.

[0064] Preferably, the processing table 10 is shaped like a racetrack from above, with six collection slots 110 symmetrically arranged on both sides, and the air blowing pipe 120 is inclined towards the conveying path; the support frame 223 is X-shaped, the slides are radially distributed, and there are five suction cups 224, with one fixed at the center.

[0065] Specifically, the six collection tanks 110 symmetrically arranged on the racetrack-shaped processing table 10 precisely correspond to the workstations of six polishing heads 6232 with different mesh sizes, forming a highly efficient graded polishing production line. The inclined air pipe 120 removes residual liquid from the glass surface with directional airflow and guides it into the collection tanks 110. Combined with the radial sliding grooves of the X-shaped support frame 223 and the five-point adaptive system formed by the central fixed suction cup 224 and the four-way adjustable suction cup 224, the circular glass is firmly clamped and the center positioning accuracy is ensured, which significantly improves the efficiency and surface quality consistency of double-sided graded polishing of multi-size glass.

[0066] Preferably, there are six drive shafts 614 and six sets of polishing components 620; the number of conveying components 220 of the annular conveying mechanism 20 is eight, of which six sets correspond to the polishing station, one set corresponds to the clamping and flipping station, and one set corresponds to the loading and unloading station.

[0067] Specifically, six drive shafts 614 and six polishing components 620 precisely correspond to six polishing stations, forming a complete graded polishing sequence. Each station is equipped with polishing heads 6232 of different mesh sizes to achieve progressive fine finishing of the glass surface. Among the eight conveying components 220, six groups synchronously carry the glass for multi-stage polishing, one group is dedicated to the clamping and flipping station to achieve automatic double-sided flipping of the glass, and one group is responsible for the loading and unloading station to ensure continuous material supply. The three work together to form a fully closed-loop automated production line, eliminating waiting time between processes, improving equipment utilization, and avoiding positioning errors caused by manual intervention.

[0068] Preferably, a slide rail slider module b721 is installed between the follower frame 722 and the lifting frame 712. The follower frame 722 is slidably connected to the lifting frame 712 through the slide rail slider module b721. The screw mechanism includes a bidirectional screw 723 and a motor d724. The bidirectional screw 723 is rotatably mounted on the lifting frame 712, and the motor d724 is horizontally fixed on the lifting frame 712.

The two ends of the bidirectional screw 723 are distributed and pass through two sets of follower frames 722. The follower frame 722 is equipped with a threaded pair that matches the bidirectional screw 723.

[0069] Specifically, the slide rail slider module b721 provides high-precision linear guidance for the follower frame 722. Combined with the bidirectional lead screw 723 driven by the motor d724 through the sprocket and chain, it forces the two follower frames 722 to open and close synchronously and symmetrically along the slide rail slider module b721, eliminating center offset when clamping glass and ensuring that the center of circular glass of different sizes is always aligned with the flipping axis. At the same time, the sprocket and chain drive effectively overcomes the torsional deformation of the long-axis bidirectional lead screw 723, ensuring bidirectional balance of clamping force for large-size glass, avoiding the risk of micro-cracks caused by uneven pressure on the glass surface, and improving flipping stability and safety.

[0070] Preferably, the linkage transmission mechanism includes: a synchronous pulley d732 coaxially fixed to the clamping member 731, a motor e735 mounted on the outer wall of the lifting frame 712, a synchronous shaft 734 driven by the motor e735, a synchronous pulley e736 slidably sleeved on the synchronous shaft 734, and a synchronous belt c733 connecting the synchronous pulley d732 and the synchronous pulley e736.

[0071] Specifically, a dynamic linkage core is formed by the synchronous shaft 734 passing through the slidingly sleeved synchronous wheel e736. When the motor e735 drives the synchronous shaft 734 to rotate, the keyway structure forces the synchronous wheel e736 to rotate synchronously in the circumference. Then, the synchronous belt c733 precisely transmits the power to the synchronous wheel d732, driving the clamping parts 731 on both sides to achieve absolute synchronous flipping. The sliding sleeve design allows the synchronous wheel e736 to move freely along the axial direction of the synchronous shaft 734, perfectly adapting to the positional changes when the clamping component 720 adjusts the spacing of the follower frame 722, ensuring that the flipping action of large-size glass is always free from transmission interference, eliminating the flipping angle deviation caused by glass size switching, and ensuring the consistency of the double-sided polishing position.

[0072] Preferably, the synchronous pulley e736 is rotatably connected to the follower frame 722, a key is installed on the synchronous shaft 734, and a matching keyway is provided on the inner wall of the synchronous pulley e736.

[0073] Specifically, the rigid meshing of the key and keyway forces the synchronizing wheel e736 to be absolutely synchronized with the synchronizing shaft 734 in the circumferential direction, completely eliminating the risk of transmission slippage and ensuring precise power transmission of the motor e735; at the same time, the synchronizing wheel e736 is rotatably connected to the follower frame 722 through an independent bearing, allowing the keyway to slide freely along the axial direction of the synchronizing shaft 734, perfectly adapting to the axial displacement when the clamping assembly 720 adjusts the spacing of the follower frame 722 while ensuring zero torque loss transmission.

[0074] Preferably, the processing table 10 is equipped with side baffles 50 on both sides to prevent polishing liquid from splashing.

[0075] Working principle: The eight conveying components 220 of the circular conveying mechanism 20 grip the glass via vacuum suction cups 224 and move it stepwise along the circular track 210. Station 1 is the loading and unloading station; stations 2-4 perform #400 / #800 / #1500 grit polishing on the A side of the circular glass; station 5 is the glass flipping station, where the clamping and flipping mechanism 70 completes a 180° glass flipping; stations 6-8 perform sequential polishing on the B side of the circular glass (see attached diagram). Figure 14(1-8 in the text correspond to the aforementioned workstations respectively). During the polishing process, motor a624 drives lead screw 6241 to push follower 623 to radially adjust the position of polishing head 6232. Motor b626 drives polishing head 6232 to rotate via synchronous belt b627, tension wheel 625, and synchronous wheel b6233. Cylinder a632 precisely controls the polishing pressure. When flipping, bidirectional lead screw 723 drives follower frame 722 to clamp the glass. Synchronous shaft 734 with keyway engagement drives clamping part 731 to rotate at a uniform speed via synchronous belt c733. Synchronous wheel e736 slides axially to compensate for dimensional changes. When the glass leaves the station, 30° inclined air pipe 120 removes 90% of the residual liquid with 0.5MPa airflow and introduces it into classification collection tank 110, realizing double-sided six-level polishing, center positioning deviation ≤0.2mm, and yield rate ≥99.2% of fully closed-loop precision processing.
