Description

Technical Field

[0001] The present application relates to the technical field of rounding machines, and in particular to a line rounding machine. Background Art

[0002] Glass is ubiquitous in our daily lives, used in buildings to block wind and transmit light, and in furniture to enhance its aesthetics. Due to its wide range of applications, glass comes in a variety of shapes. Inline rounding machines are a common piece of equipment on glass production lines. They are primarily used to grind and polish the edges of round glass during production, before transferring the round glass to the next processing step.

[0003] Current in-line rounding machines consist of a frame with a fixed conveyor belt inside. One end of the conveyor belt serves as the feed end, while the other serves as the discharge end. Grinding motors are located on either side of the conveyor belt within the frame, each with a diamond wheel mounted on its output end. These motors enclose a glass processing station. To edge-grind the glass, the glass is first placed onto the conveyor belt from the feed end. The conveyor belt then transports the glass to the processing station. The grinding motors are then activated, allowing the motors to grind and polish the glass's curved edges. Finally, the glass is transported from the discharge end of the conveyor belt to the next process, completing the polishing of the glass's curved edges.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology. When the glass is transported from the conveyor belt, the glass may not be transported to the processing position in the center due to the incorrect placement. Eventually, the rotating diamond wheel may damage the glass, affecting the quality and efficiency of the glass grinding process. Summary of the Invention

[0005] In order to facilitate the correction of the glass to be processed and to transport it to the processing position in the center, the present application provides an inline rounding machine.

[0006] This application provides a line rounding machine, which adopts the following technical solutions:

[0007] A connecting rounding machine comprises a frame, a conveyor belt is provided in the frame, the two ends of the conveyor belt are respectively set as a feeding end and a discharging end, a processing position is provided in the frame, a clamping mechanism for clamping the glass on the processing position is provided in the frame, and a grinding device for processing the glass on the processing position is provided on the frame, a first positioning plate is provided for moving and lifting above the conveyor belt near the feeding end, a first abutment block is symmetrically provided on the bottom surface of the first positioning plate, a second positioning plate is provided for moving and lifting above the conveyor belt near the discharging end, and a second abutment block is symmetrically provided on the bottom surface of the second positioning plate.

[0008] By adopting the above technical solution, after the round glass is placed on the conveyor belt from the feeding end, the first positioning plate is driven to move toward the direction close to the feeding end of the conveyor belt, and the first positioning plate simultaneously drives the two first abutting blocks on the bottom surface to move toward the direction close to the feeding end of the conveyor belt. Under the conveying action of the conveyor belt, the arc edge of the round glass abuts the two first abutting blocks at the same time and performs two-point centering limit. Then the second positioning plate is driven to move toward the direction close to the processing position, and the second positioning plate simultaneously drives the two second abutting blocks on the bottom surface to move toward the direction close to the processing position. At this time, the distance between the vertical center axis of each second abutting block and the vertical center axis of the processing position is equal to the radius of the round glass.

[0009] Then the first positioning plate is moved and raised to release the restriction on the round glass, and the conveyor belt moves the round glass toward the processing position until the arc edge of the round glass abuts against the two second abutting blocks. At this time, the round glass is centered on the processing position; then the round glass is clamped and fixed by the clamping mechanism, and finally it is polished by the polishing device to complete the processing. The feed of the glass to be processed is pre-positioned by the two first abutting blocks, and the working position of the round glass is corrected by the two second abutting blocks. This not only improves the stability of the round glass in being transported to the processing position, but also helps to improve the precision and efficiency of polishing.

[0010] Optionally, a base is provided on the inner side of the top of the frame, and the base is respectively provided with a driving component for driving the first positioning plate and the second positioning plate to move and lift, and the driving component includes two driving motors, and the two driving motors are symmetrically arranged on the bottom surface of the base, and the output shafts of the two driving motors are respectively provided with a first screw rod, and the threaded sleeves of the two first screw rods are provided with a connecting frame, and a first cylinder is provided on one side of the two connecting frames, and the telescopic ends of the two first cylinders are respectively connected to the first positioning plate and the second positioning plate.

[0012] Optionally, the clamping mechanism includes a second cylinder and a pressure plate, the second cylinder is arranged in the frame and is located below the processing position, the telescopic end of the second cylinder is rotatably provided with a lifting plate, the bottom surface of the machine base is rotatably provided with a rotating column, the top of the rotating column passes through the machine base and extends into the machine base, the machine base is provided with a first driving member for driving the rotating column to rotate, the pressure plate is arranged above the processing position, and the pressure plate is installed at the bottom end of the rotating column.

[0013] By adopting the above technical solution, when the circular glass on the processing position needs to be clamped and fixed, the second cylinder is started first, and the second cylinder drives the lifting plate to rise, and the lifting plate thereby drives the circular glass on the processing position to rise and separate from the conveyor belt. At this time, the circular glass is pressed against the bottom surface of the pressure plate. When the rotating column is driven to rotate by the first driving member, the rotating column drives the pressure plate to rotate. Under the action of friction, the pressure plate drives the circular glass to rotate, and the circular glass drives the lifting plate to rotate. At this time, the grinding device grinds the rotating circular glass, which is beneficial to improve the clamping and fixation of the circular glass on the processing position and achieve grinding stability.

[0015] By adopting the above technical solution, when the lifting plate drives the circular glass to be pressed toward the pressure plate, the circular glass squeezes the pressure plate, the pressure plate compresses the spring, and the spring elastically deforms, thereby buffering the squeezing force of the circular glass and avoiding rigid squeezing as much as possible to cause damage to the surface of the circular glass.

[0016] Optionally, the grinding device includes two coarse grinding wheels and two fine grinding wheels, and the two coarse grinding wheels and the two fine grinding wheels are respectively arranged obliquely and symmetrically on both sides of the processing position, and the two coarse grinding wheels and the two fine grinding wheels are respectively arranged at intervals. The grinding device also includes a moving mechanism for driving the fine grinding wheels and the coarse grinding wheels to move.

[0017] By adopting the above technical solution, when circular glass needs to be ground, the two rough grinding wheels and the two fine grinding wheels are driven to rotate respectively, and the rotation direction is opposite to the rotation direction of the circular glass. Then, the two rough grinding wheels are driven at the same time by the moving mechanism to rough-grind the circular glass. After the circular glass rotates 180°, the two fine grinding wheels are driven at the same time by the moving mechanism to fine-grind the circular glass. During the entire grinding process, the circular glass only needs to rotate one circle to complete the entire grinding process. Under the arrangement of this structure, it is beneficial to improve the efficiency of circular glass grinding and maximize cost-effectiveness.

[0019] By adopting the above technical solution, when the second screw is started to rotate by the second driving member, the second screw drives the moving block to move, and the moving block drives the grinding head motor to move through the grinding box, and the grinding head motor thereby drives the fine grinding wheel or the rough grinding wheel to move in the horizontal direction. When the grinding head motor is started, the grinding head motor drives the fine grinding wheel or the rough grinding wheel to rotate in the opposite direction to the circular glass, which is beneficial to improve the stability of the fine grinding wheel or the rough grinding wheel in processing the circular glass.

[0021] By adopting the above technical solution, when the third driving member drives the third screw to rotate, the third screw drives the grinding head motor to move up and down through the lifting block, and the grinding head motor thereby drives the fine grinding wheel or the coarse grinding wheel to move up and down. When one layer of the fine grinding wheel or the coarse grinding wheel is worn out, the other layer of the fine grinding wheel or the coarse grinding wheel can be used for grinding by lifting the fine grinding wheel or the coarse grinding wheel, which is beneficial to improve the service life of the fine grinding wheel or the coarse grinding wheel.

[0022] Optionally, a repair component for repairing the fine grinding wheel or the rough grinding wheel is provided in the grinding box, and the repair component includes a third cylinder. The third cylinder is provided in the grinding box, and the telescopic end of the third cylinder passes through the grinding box and extends to the outside of the side wall of the grinding box. The telescopic end of the third cylinder is provided with a repair knife.

[0023] By adopting the above technical solution, when the surface of the fine grinding wheel or the rough grinding wheel is damaged, the third cylinder can be started, and the telescopic end of the third cylinder drives the repair knife to move toward the direction close to the fine grinding wheel or the rough grinding wheel. At this time, the repair knife abuts the fine grinding wheel or the rough grinding wheel and cuts or repairs its surface, which is beneficial to improve the service life of the fine grinding wheel or the rough grinding wheel.

[0024] Optionally, a threshold protection mechanism is provided on the side of the frame close to the feed end, and the threshold protection mechanism includes a limit cover. A support platform is provided on the side of the frame close to the feed end, and the limit cover is provided on the top surface of the support platform.

The two moving seats respectively drive the two threshold limit blocks to move towards or away from each other. At this time, the two threshold limit blocks are enclosed to form the maximum diameter distance allowing the round glass to enter. Under the action of the threshold protection mechanism, it is not only beneficial to protect the round glass with too large radius from damaging the rounding machine, but also beneficial to check whether the sizes of the rounding machines in the same batch are uniform, which is beneficial to improve the stability of the round glass grinding process.

[0026] Optionally, the connecting rod assembly includes two first connecting rods, two second connecting rods and two auxiliary slides, the two auxiliary slides are symmetrically arranged on both sides of the fourth cylinder, and the two auxiliary slides are respectively located between the fourth cylinder and the two moving seats, one end of the two first connecting rods is respectively hinged to the two auxiliary slides, the other end of the two first connecting rods is respectively hinged to the two sides of the push block, one end of the two second connecting rods is respectively hinged to the auxiliary slides, and the other end of the two second connecting rods is respectively hinged to one side of the two moving seats.

[0027] By adopting the above technical solution, when the push block moves in the direction away from the fourth cylinder, the push block drives the auxiliary slide to slide through the first connecting rod, and the auxiliary slide then drives the moving seat to move towards each other through the second connecting rod, which is beneficial to improve the stability of the simultaneous movement of the two prefabricated limit blocks.

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] Example:

[0039] See also Figure 1 and Figure 2 A line rounding machine includes a frame 1. The frame 1 is placed on the ground, and a conveyor belt 11 is fixed inside the frame 1, and the conveyor belt 11 is used to convey round glass. One end of the conveyor belt 11 is set as a feeding end 12, and the other end of the conveyor belt 11 is set as a discharging end 13. A processing position 14 for grinding round glass is provided in the frame 1, and the processing position 14 is located in the middle position of the conveyor belt 11. A clamping mechanism and a grinding device are also provided in the frame 1. The clamping mechanism is used to clamp and fix the round glass on the processing position 14, and the grinding device is used to grind the arc edge of the round glass clamped and fixed on the processing position 14.

[0040] A first positioning plate 2 is moved upward and downward above the conveyor belt 11 near the feed end 12. A first abutment block 21 is symmetrically fixed to the bottom surface of the first positioning plate 2. This two-point positioning method pre-positions the round glass entering from the feed end 12. A second positioning plate 3 is moved upward and downward near the discharge end 13 of the conveyor belt 11. A second abutment block 31 is symmetrically fixed to the bottom surface of the second positioning plate 3. By adjusting the distance between the second abutment block 31 and the processing station 14, the round glass is delivered to the processing station 14 in a centered manner.

[0041] See also Figure 2In order to improve the stability of the movement and lifting of the first positioning plate 2 and the second positioning plate 3, the frame 1 is provided with a drive assembly, which includes a drive motor 41. A base 4 is fixed on the inner side of the top of the frame 1. There are two drive motors 41, which are symmetrically fixed to the front and rear ends of the bottom surface of the base 4. The drive shafts of the two drive motors 41 are coaxially fixed with first screw rods 42, and the side walls of the two first screw rods 42 are respectively threaded with connecting frames 43. One side of the two connecting frames 43 is respectively fixed with a first cylinder 44. The telescopic end of the first cylinder 44 near the feed end 12 is fixedly connected to the top surface of the first positioning plate 2. The telescopic end of the first cylinder 44 near the discharge end 13 is fixedly connected to the top surface of the second positioning plate 3.

[0042] When it is necessary to pre-position the round glass, the drive motor 41 near the feed end 12 is first started. The drive shaft of the drive motor 41 drives the first screw 42 to rotate, and the first screw 42 drives the connecting frame 43 to move along the length direction of the conveyor belt 11. When the first positioning plate 2 moves to just above the feed end 12, the first cylinder 44 is started. The telescopic end of the first cylinder 44 drives the first positioning plate 2 to descend, and the first positioning plate 2 simultaneously drives the two first abutment blocks 21 to descend. In this embodiment, the pre-positioning method adopts a two-point positioning method. When the arc edge of the round glass abuts one of the first abutment blocks 21, under the continuous conveying action of the conveyor belt 11, the arc edge of the round glass will simultaneously abut the other first abutment block 21, completing the pre-positioning.

[0043] Similarly, to facilitate the centering of the round glass onto the processing station 14, the radius of the round glass is first determined in advance. Then, the second positioning plate 3 is ultimately driven toward the processing station 14 using the same driving method. At this point, the distance between the two second abutment blocks 31 and the vertical axis of the processing station 14 is equal to the radius of the round glass. The first positioning plate 2 is then driven away from the round glass. The round glass, under the action of the conveyor belt 11, simultaneously abuts the two second abutment blocks 31, and the round glass is now centered on the processing station 14.

[0044] Specifically, participate Figure 2 The clamping mechanism includes a second cylinder 5 and a pressure plate 51. The second cylinder 5 is fixed in the frame 1, and the second cylinder 5 is located directly below the processing position 14. The telescopic end of the second cylinder 5 is coaxially rotated with a lifting plate 52, and the lifting plate 52 is also located directly below the processing position 14. A rotating column 53 is rotated on the bottom surface of the machine base 4. The top end of the rotating column 53 passes through the machine base 4 and extends into the machine base 4. A first driving member 54 for driving the rotating column 53 to rotate is provided in the machine base 4. The pressure plate 51 is coaxially installed at the bottom end of the rotating column 53, and the pressure plate 51 is located directly above the processing position 14.

[0045] See also Figure 2 and Figure 3In order to avoid rigid contact when the round glass is pressed against the pressure plate 51, a buffer assembly is provided in the rotating column 53, and the buffer assembly includes a spring 55 and a buffer rod 56. A buffer groove 57 is provided in the rotating column 53, and the buffer groove 57 is provided along the vertical direction of the rotating column 53. The buffer rod 56 slides and rises in the buffer groove 57, and the bottom end of the buffer rod 56 passes through the buffer groove 57 and extends to the outside of the bottom end of the rotating column 53, and the bottom end of the buffer rod 56 is coaxially fixedly connected to the top surface of the pressure plate 51. The spring 55 is installed in the buffer groove 57, and one end of the spring 55 is fixedly connected to the top end of the buffer rod 56, and the other end of the spring 55 is fixedly connected to the inner top groove wall of the buffer groove 57.

[0046] When the round glass needs to be fixed on the processing position 14, the second cylinder 5 is first activated. The telescopic end of the second cylinder 5 drives the lifting plate 52 to rise. The rising lifting plate 52 supports the round glass and simultaneously separates the round glass from the conveyor belt 11. When the round glass is pressed toward the pressing plate 51, the round glass drives the pressing plate 51 to be pressed toward the rotating column 53. At this time, the spring 55 elastically deforms, thereby cushioning the lifting and squeezing of the round glass, and minimizing the situation where the round glass is rigidly connected to the pressing plate 51 and causes surface damage due to extrusion.

[0047] When the round glass needs to be polished, the first driving member 54 is used to drive the rotating column 53 to rotate, and the rotating column 53 drives the pressure plate 51 to rotate through the buffer rod 56. Under the friction force between the pressure plate 51 and the round glass, the pressure plate 51 drives the round glass to rotate, and the round glass then drives the lifting plate 52 to rotate. At this time, the rotating round glass is polished by the polishing device.

[0048] For details, see Figure 1 and Figure 4 The grinding device includes a coarse grinding wheel 76 and a fine grinding wheel 77. In this embodiment, the number of the coarse grinding wheel 76 and the fine grinding wheel 77 is set to two. The two coarse grinding wheels 76 and the two fine grinding wheels 77 are respectively located on both sides of the processing position 14 obliquely symmetrically, and the two coarse grinding wheels 76 and the two fine grinding wheels 77 are respectively arranged at intervals, and the rotation direction of the two coarse grinding wheels 76 and the two fine grinding wheels 77 is opposite to the rotation direction of the circular glass.

[0049] See also Figure 4In order to facilitate the movement of the two rough grinding wheels 76 and the two fine grinding wheels 77 in the frame 1 and to grind the circular ground glass, the grinding device also includes a moving mechanism, and each rough grinding wheel 76 and each fine grinding wheel 77 is correspondingly provided with a moving mechanism. The moving mechanism includes a fixed seat 6, which is fixed in the frame 1, and the fixed seat 6 is tilted relative to the conveying direction of the conveyor belt 11, and the inclined end of the fixed seat 6 faces the center of the processing position 14. A second screw rod 61 rotates in the fixed seat 6, and a moving block 63 slides in the fixed seat 6. The second screw rod 61 passes through the moving block 63 and is threadedly connected to the moving block 63. A second driving member 62 is provided in the fixed seat 6 for driving the second screw rod 61 to rotate. A grinding box 7 slides on the top surface of the fixed seat 6, and the top surface of the moving block 63 passes through the fixed seat 6 and is fixedly connected to the bottom surface of the grinding box 7. A grinding head motor 72 is provided on the side of the grinding box 7 that is moved upward and downward toward the processing position 14 , and a coarse grinding wheel 76 or a fine grinding wheel 77 is mounted on the driving shaft of the grinding head motor 72 .

[0050] It is worth noting that the coarse grinding wheel 76 or the fine grinding wheel 77 can be installed by threaded installation. The coarse grinding wheel 76 or the fine grinding wheel 77 is sleeved on the driving shaft of the grinding head motor 72 and then locked by bolts.

[0051] See also Figure 4 To facilitate the lifting and lowering of the grinding head motor 72, the grinding box 7 is equipped with a lifting assembly, which includes a lifting seat 71. The lifting seat 71 is fixed to the side of the grinding box 7 facing the processing position 14. The lifting seat 71 rotates a third screw 73. A lifting block 74 slides and rises within the lifting seat 71. The third screw 73 is threaded through the lifting block 74 and is threadedly connected to the lifting block 74. One side of the lifting block 74 passes through the lifting seat 71 and extends outside the side wall of the lifting seat 71. One side of the lifting block 74 is fixedly connected to the side wall of the grinding head motor 72. The lifting seat 71 is equipped with a third driving member 75 for driving the third screw 73 to rotate.

[0052] When it is necessary to drive the coarse grinding wheel 76 or the fine grinding wheel 77 close to the processing position 14, the second driving member 62 is first used to drive the second screw rod 61 to rotate, and the second screw rod 61 drives the grinding box 7 to move toward the processing position 14 through the moving block 63. The grinding box 7 drives the grinding head motor 72 to move toward the processing position 14 through the lifting seat 71, and the grinding head motor 72 thereby drives the coarse grinding wheel 76 or the fine grinding wheel 77 to move toward the processing position 14. At this time, the arc edge of the circular glass can be ground by the coarse grinding wheel 76 or the fine grinding wheel 77.

[0053] Since the coarse grinding wheel 76 or the fine grinding wheel 77 has a thickness, and only one thickness is used to grind the circular glass, when one thickness is worn and the other thickness is needed, the third driving member 75 drives the third screw 73 to rotate, and the third screw 73 drives the grinding head motor 72 to descend via the lifting block 74, and the grinding head motor 72 drives the coarse grinding wheel or the fine grinding wheel 77 to descend, thereby achieving the use of the other thickness to grind the arc edge of the circular glass, thereby extending the service life of the coarse grinding wheel 76 or the fine grinding wheel 77.

[0054] It is worth mentioning that, with the coarse grinding wheel 76 and the fine grinding wheel 77 spaced apart, the round glass only needs one rotation to complete the entire grinding operation. If the round glass needs to be further polished, polishing wheels can be installed on the drive shafts of the two diagonally opposed grinding head motors 72, so that the entire grinding and polishing process only requires one and a half rotations, which is conducive to improving the grinding efficiency.

[0055] It should be noted that the first driving member 54 , the second driving member 62 and the third driving member 75 can all be reduction motors.

[0056] See also Figure 4 To facilitate repairing the surface wear of the rough grinding wheel 76 or the fine grinding wheel 77, a repair assembly is provided in the grinding box 7. The repair assembly includes a third cylinder 78. The third cylinder 78 is fixed in the grinding box 7. The telescopic end of the third cylinder 78 passes through the grinding box 7 and extends to the side of the grinding box 7 facing the processing position 14. A repair knife 79 is fixed to the telescopic end of the third cylinder 78.

[0057] When the surface of the coarse grinding wheel 76 or the fine grinding wheel 77 is worn, or a layer needs to be removed, the coarse grinding wheel 76 or the fine grinding wheel 77 is finally moved up and down by the lifting base 71 and aligned with the repair knife 79. Then the third cylinder 78 is started, and the telescopic end of the third cylinder 78 drives the repair knife 79 toward the coarse grinding wheel 76 or the fine grinding wheel 77. While the coarse grinding wheel 76 or the fine grinding wheel 77 rotates, the repair knife 79 repairs or removes the surface.

[0058] See also Figure 5 and Figure 6In order to avoid the collision of large-radius circular glass with the coarse grinding wheel 76 or the fine grinding wheel 77 as much as possible, and to facilitate the detection of whether the radius of the same batch of glass is the same, the frame 1 is provided with a threshold protection mechanism, and the threshold protection mechanism includes a limit cover 8. A support platform 15 is fixed on the side of the frame 1 close to the feed end 12. The limit cover 8 is in the shape of a gantry, and the limit cover 8 is fixed to the top surface of the support platform 15. There are threshold limit blocks 81 that move symmetrically in the limit cover 8, and the opposite sides of the two threshold limit blocks 81 enclose a space for the circular glass to enter. The top surfaces of the two threshold limit blocks 81 pass through the limit cover 8 respectively, and are respectively fixed with a moving seat 82. The two moving seats 82 are slidably connected to the limit cover 8. A fourth cylinder 83 is fixed to the top surface of the limit cover 8, and a push block 84 is fixed to the telescopic end of the fourth cylinder 83. The push block 84 is slidingly connected to the limit cover 8. The two moving seats 82 are symmetrically arranged with the fourth cylinder 83, and the push block 84 is provided with a connecting rod assembly for simultaneously driving the two moving seats 82 to move.

[0059] For details, see Figure 6 There are two sets of connecting rod assemblies, symmetrically arranged around the fourth cylinder 83. Each set of connecting rod assemblies is located between the fourth cylinder 83 and the movable base 82. Each set of connecting rod assemblies includes a first connecting rod 85, a second connecting rod 86, and an auxiliary slide 87. The auxiliary slide 87 slides on the top surface of the limiting cover 8. One end of the first connecting rod 85 is hinged to the auxiliary slide 87, and the other end of the first connecting rod 85 is hinged to the push block 84. One end of the second connecting rod 86 is hinged to the auxiliary slide 87, and the other end of the second connecting rod 86 is hinged to the movable base 82.

[0060] When it is necessary to set the maximum threshold for the entry of round glass, the fourth cylinder 83 is first activated. The telescopic end of the fourth cylinder 83 drives the push block 84 to move. The push block 84 drives the auxiliary slide 87 to move via the first connecting rod 85. The auxiliary slide 87 drives the moving seat 82 to move via the second connecting rod 86. At this time, the two threshold limit blocks 81 move toward or away from each other at the same time. This helps to minimize the risk of round glass with a radius greater than the maximum threshold being transported to the processing position 14 and damaging the grinding head motor 72. It also helps to check whether the radius of the round glass in the current batch is the same. If not, the radius of the round glass is smaller or larger than the entry space.

[0061] It is worth noting that in this embodiment, infrared sensors can be installed at the feed end 12 and the processing station 14, and are electrically connected to all the electrical devices in this embodiment. The infrared sensors are used to sense the delivery position of the round glass and send instructions to the corresponding electrical devices. This process is conventional and will not be described in detail here. A control cabinet 9 is also installed on the frame 1, which can be used to control the opening and closing of the line rounding machine.

[0062] The working principle of a line grinding machine:

[0063] Before polishing the round glass, the maximum threshold for allowing the round glass to enter the feed end 12 is set. At this time, the fourth cylinder 83 can be activated first. The telescopic end of the fourth cylinder 83 drives the push block 84 to move. Under the action of the first connecting rod 85, the auxiliary slide 87 and the second connecting rod 86, the two threshold limit blocks 81 eventually move toward each other. After the maximum threshold is set, the round glass is input from the feed end 12. At the same time, the drive assembly and the first cylinder 44 eventually drive the first positioning plate 2 to move toward the feed end 12. Under the two-point positioning action of the two first abutment blocks 21, the round glass is pre-positioned so that the round glass is centered on the conveyor belt 11.

[0064] Then, the second positioning plate 3 is finally driven to move toward the processing position 14. At this time, the distance between the two second abutment blocks 31 and the center of the processing position 14 is equal to the radius of the circular glass, and when the circular glass abuts against the two second abutment blocks 31, the circular glass is centered on the processing position 14.

[0065] The second cylinder 5 is then activated, and its telescopic end drives the lifting plate 52 upward. This pushes the round glass toward the pressing plate 51, freeing it from the conveyor belt 11. The spring 55 within the buffer rod 56 cushions the instantaneous squeezing force on the round glass, preventing damage to the glass surface caused by rigid collisions. The first driving member 54 then drives the rotating column 53 to rotate, which in turn drives the buffer rod 56 to rotate. The buffer rod 56, via the pressing plate 51, drives the round glass to rotate on the processing station 14.

[0066] Then, the two rough grinding wheels 76 are simultaneously driven to rotate in opposite directions to perform rough grinding on the circular glass. After the circular glass rotates half a circle, the two fine grinding wheels 77 are simultaneously driven to rotate in the same direction as the two rough grinding wheels 76 to perform fine grinding on the circular glass. After the circular glass rotates another half circle, the fine grinding of the circular glass is completed. The circular glass only needs to rotate one circle during the entire grinding process, which improves the grinding efficiency.

[0067] When the grinding process is completed, the round glass is finally placed back on the conveyor belt 11 through the second cylinder 5, and the round glass is transported to the next process through the discharge end 13.

[0068] To sum up, the first positioning plate 2 pre-positions the circular glass on the conveyor belt 11, and the second positioning plate 3 centers the circular glass on the processing position 14, which not only ensures the stability of the grinding process of the circular glass on the processing position 14, but also helps to improve the accuracy and efficiency of the grinding of the circular glass.

[0069] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
