Description

Technical Field

[0001] This invention belongs to the field of glass production technology, specifically a glass edging machine. Background Technology

[0002] After glass is initially processed into a flat shape or cut, its edges will have sharp corners, requiring edge grinding. After edge grinding, small cracks and micro-cracks on the glass edges are removed, eliminating localized stress concentration and increasing the strength of the glass. Furthermore, after coarse edge grinding, fine edge grinding, and polishing, the quality and aesthetics of the glass are further improved.

[0003] Currently, L-shaped glass edging production lines, consisting of two sets of conveyor belts and two sets of straight double-sided edging machines, are commonly used to edge the four sides of glass. However, L-shaped glass edging production lines have the problems of large floor space and high production line cost. Furthermore, the two sets of straight double-sided edging machines need to edge different sides of the glass sequentially, resulting in low edging efficiency. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a glass edging machine for glass production, so as to at least partially solve the problems mentioned in the background art.

[0005] This invention provides the following technical solution: A glass edging machine for production, comprising: The grinding wheels are arranged in four groups in an array; The edge-grinding drive mechanism is used to simultaneously drive four sets of edge-grinding wheels to move horizontally relative to the four sides of the glass.

A negative pressure box is set between the upper carrying section and the lower return section of the conveyor belt. The upper carrying section of the conveyor belt is in contact with the upper surface of the negative pressure box, and a negative pressure channel is opened on the top wall of the negative pressure box. A negative pressure pump is connected to a negative pressure box via an air pipe. The negative pressure pump is used to pump the negative pressure box to a negative pressure state. The suction cups are configured to move relative to the negative pressure channels as the conveyor belt rotates. Multiple sets of negative pressure channels are provided on the top wall of the negative pressure box. Multiple rows of suction cups are provided in the width direction of the conveyor belt. Each row of suction cups corresponds to a set of negative pressure channels. The suction cups are configured to slide down under the weight of the glass and are connected to the negative pressure box through negative pressure slots and negative pressure channels.

The upper end of the load-bearing plate is engaged and slidably disposed in the load-bearing groove. The mounting plate is connected to the load-bearing plate.

[0013] It should also be noted that, through the relative positions of the first and second bevel gears and the screw thread direction, the drive plates on the four sets of screws move in the same direction (clockwise or counterclockwise) to avoid interference between the grinding positions of the four sets of grinding wheels.

[0014] Furthermore, the negative pressure slot includes a sliding hole and a lifting hole, the lifting hole is located below the sliding hole, the diameter of the lifting hole is larger than the diameter of the sliding hole, the suction cup is slidably disposed in the sliding hole, and a negative pressure hole is formed on the side wall of the suction cup; The lower end of the suction cup is provided with a baffle. The diameter of the baffle is larger than that of the sliding hole and smaller than that of the lifting hole. The baffle is slidably disposed in the lifting hole. A support plate is provided on the inner wall of the lifting hole. A return spring is provided between the support plate and the baffle.

[0015] Furthermore, two sets of centering adjustment mechanisms are provided on both sides of the feed end of the conveyor belt, and the centering adjustment mechanism includes: Side panels; The cylinder is fixedly mounted on the side plate. An adjustment frame is connected to the free end of a push cylinder, and an adjustment groove is provided on the side of the adjustment frame near the conveyor belt; The guide roller is rotatably positioned within the adjustment groove.

[0016] It should be noted that a guide rod is also provided on the side plate. The guide rod is connected to the adjustment frame. The guide rod can be an integral rod that is slidably set on the side plate, or it can be a sleeve and slide rod with telescopic function. The guide rod works with the push cylinder to stably adjust the position of the adjustment frame.

[0017] Furthermore, the support frame is provided with an auxiliary clamping and fixing mechanism, which includes: The clamping cylinder is fixedly mounted on the support frame; The clamping plate is connected to the free end of the clamping cylinder.

[0018] Furthermore, the support frame is equipped with a photoelectric sensor, which is located near the longitudinal screw without a position adjustment component.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0025] See Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 11 This embodiment provides a glass edging machine for production, comprising: Grinding wheels 1 are arranged in four groups in an array; The edge grinding drive mechanism 2 is used to simultaneously drive four sets of edge grinding wheels 1 to move relative to the four sides of the glass 46. The four sets of edge grinding wheels 1 are simultaneously driven by the edge grinding drive mechanism 2 to move relative to the four sides of the glass 46. During the movement, the four sets of edge grinding wheels 1 perform edge grinding on the four sides of the glass 46, thereby improving the edge grinding efficiency of the four sides of the glass 46. Conveyor belt 3 is used to carry and transport glass 46. Multiple sets of negative pressure slots 4 are opened through the conveyor belt 3. Suction cup 5 is slidably disposed within negative pressure groove 4; The negative pressure box 6 is located between the upper bearing section and the lower return section of the conveyor belt 3. The upper bearing section of the conveyor belt 3 is in contact with the upper surface of the negative pressure box 6, and a negative pressure channel 7 is provided on the top wall of the negative pressure box 6. The negative pressure pump 8 is connected to the negative pressure box 6 via the air pipe 9. The negative pressure pump 8 is used to pump the negative pressure box 6 to a negative pressure state. The suction cup 5 is configured to move relative to the negative pressure channel 7 as the conveyor belt 3 rotates. Multiple sets of negative pressure channels 7 are provided on the top wall of the negative pressure box 6. Multiple rows of suction cups 5 are provided in the width direction of the conveyor belt 3. Each row of suction cups 5 corresponds to a set of negative pressure channels 7. When the glass 46 is placed on the suction cup 5, a downward force is applied to the suction cup 5 under the action of the gravity of the glass 46. The suction cup 5 moves down along the negative pressure slot 4. When the glass 46 moves to the negative pressure channel 7 with the conveyor belt 3, the suction cup 5 is connected to the negative pressure box 6 through the negative pressure channel 7. Under the action of the negative pressure pump 8, the negative pressure is applied to the glass 46 through the suction cup 5 to adsorb and fix the glass 46, ensuring the stability of the position of the glass 46 on the conveyor belt 3 when the grinding wheel 1 grinds the four sides of the glass 46.

[0026] It should be noted that the position of the negative pressure box 6 is adapted to the position of the grinding wheel 1. When the glass 46 is conveyed to the top of the negative pressure box 6 by the conveyor belt 3, the glass 46 is stably fixed on the conveyor belt 3 under the action of negative pressure. By finely adjusting the position of the grinding wheel 1, the grinding wheel 1 is made to contact the four sides of the glass 46. The four sets of grinding wheels 1 can then grind the four sides of the glass 46 respectively.

[0027] Specifically, see Figure 1 , Figure 7 , Figure 9 , Figure 13 and Figure 14 In this embodiment, the edge grinding drive mechanism 2 includes: The support frame 10 is located above the corresponding part of the conveyor belt 3 and the negative pressure box 6; The drive motor 11 is fixedly mounted on the support frame 10; The screw 12 is rotatably mounted on the support frame 10. There are four sets of screws 12, which are distributed in a rectangular structure. The four sets of grinding wheels 1 are respectively connected to the four sets of screws 12. One end of one set of screws 12 is connected to the output shaft of the drive motor 11. The transmission assembly has four sets at the four corners of the rectangular structure composed of four sets of screws 12. The transmission assembly is used for transmission between the four sets of screws 12.

[0028] During operation, the drive motor 11 drives a set of screws 12 to rotate. Under the power transmission of the transmission component, the four sets of screws 12 rotate simultaneously. The four sets of screws 12 drive the ground grinding wheel 1 to move relative to the four sides of the glass 46, and grind the four sides of the glass 46.

[0029] Specifically, see Figure 7 , Figures 9-11 , Figure 13 and Figure 14 In this embodiment, the four sets of screws 12 include two sets of parallel transverse screws 13 and two sets of parallel longitudinal screws 14. One set of transverse screws 13 is connected to the output shaft of the drive motor 11. The transmission components include: The protective shell 15 is fixedly mounted on the support frame 10; The drive shaft 16 is rotatably mounted on the protective shell 15, and the first bevel gear 17 and the first transmission gear 18 are fixedly mounted on the drive shaft 16. The second bevel gear 19 is fixedly mounted on the transverse screw 13. The second bevel gear 19 meshes with the first bevel gear 17. Through the meshing transmission between the first bevel gear 17 and the second bevel gear 19, the transverse screw 13 drives the transmission shaft 16 to rotate. The second transmission gear 20 is fixedly mounted on the longitudinal screw 14. The second transmission gear 20 meshes with the first transmission gear 18. Through the meshing transmission between the first transmission gear 18 and the second transmission gear 20, the transmission shaft 16 drives the longitudinal screw 14 to rotate.

[0030] During operation, the drive motor 11 drives a set of transverse screws 13 connected to it to rotate. Through the meshing of the first bevel gear 17 and the second bevel gear 19, the set of transverse screws 13 drives the transmission shaft 16 to rotate. Through the meshing of the first transmission gear 18 and the second transmission gear 20, the transmission shaft 16 drives the longitudinal screw 14 to rotate, and simultaneously drives four sets of screws 12 to realize the movement of the four sets of grinding wheels 1 relative to the side of the glass 46, thereby completing the simultaneous grinding of the four sides of the glass 46 and improving the grinding efficiency of the glass 46.

[0031] It is important to understand that by controlling the difference in diameter and number of teeth between the first transmission gear 18 and the second transmission gear 20, the rotational speed ratio between the transverse screw 13 and the longitudinal screw 14 is adjusted, thereby controlling the moving speed of the edging wheel 1 on the transverse screw 13 and the edging wheel 1 on the longitudinal screw 14 to meet the four-sided edging requirements of glass 46 with different aspect ratios. For example, when the diameter and number of teeth of the second transmission gear 20 are twice the diameter and number of teeth of the first transmission gear 18, the rotational speed of the longitudinal screw 14 is half the rotational speed of the transverse screw 13. Therefore, the moving speed of the edging wheel 1 on the transverse screw 13 is twice the moving speed of the edging wheel 1 on the longitudinal screw 14. This edging machine can meet the four-sided edging requirements of glass 46 with an aspect ratio less than or equal to 2:1. To meet the four-sided edging requirements of glass 46 of other specifications, the first transmission gear 18 and the second transmission gear 20 of appropriate sizes can be selected.

[0032] Specifically, see Figure 7 and Figure 11 In this embodiment, the edge grinding drive mechanism 2 further includes: Guide slide rod 21, four sets of guide slide rod 21 are provided corresponding to screw rod 12, and the two ends of guide slide rod 21 are respectively fixed on protective shell 15; The drive plate 22 is connected to the screw 12 by a thread. The drive plate 22 is slidably mounted on the guide slide 21. Under the driving action of the screw 12 and the guiding action of the guide slide 21, the drive plate 22 is ensured to move stably in the lateral or longitudinal direction.

[0033] Specifically, see Figure 7 , Figure 8 , Figure 11 and Figure 12 In this embodiment, a lifting cylinder 23 is provided on the drive plate 22 connected to the two sets of longitudinal screws 14. A position adjustment component is installed on the free end of the lifting cylinder 23 corresponding to the set of longitudinal screws 14 near the feed end of the conveyor belt 3 and on the drive plate 22 connected to the two sets of transverse screws 13. A mounting plate 24 is connected to the free end of the lifting cylinder 23 corresponding to the set of longitudinal screws 14 near the discharge end of the conveyor belt 3 and on the three sets of position adjustment components. A grinding motor 25 is provided on the mounting plate 24. The grinding wheel 1 is rotatably mounted on the mounting plate 24. The grinding wheel 1 is connected to the output shaft of the grinding motor 25. By setting the position adjustment component, the position of the grinding wheel 1 connected to it can be adjusted. The four sets of grinding wheels 1 grind the four sides of glass 46 of different sizes at the same time. The grinding wheels 1 installed on the transverse screw 13 grind the two long sides of the glass 46, and the grinding wheels 1 installed on the longitudinal screw 14 grind the two wide sides of the glass 46. Under the action of the position adjustment component, the positions of the grinding wheels 1 corresponding to the two sets of transverse screws 13 are adjusted along the width direction of the glass 46 to meet the grinding requirements of the two long sides of the glass 46 with different widths. Under the action of the position adjustment component, the positions of the grinding wheels 1 corresponding to the set of longitudinal screws 14 are adjusted along the length direction of the glass 46 to meet the grinding requirements of the two long sides of the glass 46 with different lengths.

[0034] Specifically, see Figure 8 , Figure 11 and Figure 12 In this embodiment, the position adjustment component includes: The mounting bracket 26 has a load-bearing slide groove 27 on its lower surface, and the longitudinal section of the load-bearing slide groove 27 is T-shaped. Telescopic cylinder 28 is fixedly mounted on mounting bracket 26; The load-bearing plate 29 is connected to the free end of the telescopic cylinder 28. The upper end of the load-bearing plate 29 is engaged and slidably disposed in the load-bearing slide groove 27. The mounting plate 24 is connected to the load-bearing plate 29. Under the action of the telescopic cylinder 28, the load-bearing plate 29 is pushed to slide along the load-bearing slide groove 27, thereby adjusting the relative position of the grinding wheel 1 and the side of the glass 46. When the grinding wheel 1 contacts the side of the glass 46, the side of the glass 46 is ground as the position of the grinding wheel 1 moves.

[0035] During operation, the relative positions of the first bevel gear 17 and the second bevel gear 19, along with the thread direction of the screw 12, enable the drive plates 22 on the four sets of screws 12 to move in the same direction (clockwise or counterclockwise). This ensures that the four sets of grinding wheels 1 are always located at the four corners of the glass, preventing interference between the grinding positions of the four sets of grinding wheels 1. For example, in this embodiment, see Figure 13 Each grinding wheel 1 moves clockwise to grind the four sides of the glass 46. Specifically: the drive plate 22 of the upper set of horizontal screws 13 drives its corresponding grinding wheel 1 to move from left to right; the drive plate 22 of the lower set of horizontal screws 13 drives its corresponding grinding wheel 1 to move from right to left; the drive plate 22 of the left set of vertical screws 14 drives its corresponding grinding wheel 1 to move from bottom to top; and the drive plate 22 of the right set of vertical screws 14 drives its corresponding grinding wheel 1 to move from top to bottom. After completing the above edge-grinding action, when grinding the next piece of glass 46 that has moved into place, the drive motor 11 rotates in the opposite direction, and each edge-grinding wheel 1 moves counterclockwise to grind the four sides of the next piece of glass 46. The counterclockwise movement path of each edge-grinding wheel 1 is as follows: Figure 14Of course, a combination of clockwise and counterclockwise grinding can be used to perform two consecutive grinding operations on the side of glass 46 to further improve the grinding quality of glass 46.

[0036] Specifically, see Figure 5 In this embodiment, the negative pressure slot 4 includes a sliding hole 30 and a lifting hole 31. The lifting hole 31 is located below the sliding hole 30, and the diameter of the lifting hole 31 is larger than the diameter of the sliding hole 30. The suction cup 5 is slidably disposed in the sliding hole 30. A negative pressure hole 32 is provided on the side wall of the suction cup 5. In the initial state, the side wall of the sliding hole 30 blocks the negative pressure hole 32. When the suction cup 5 is pressed down and slid by the gravity of the glass 46, the negative pressure hole 32 enters the lifting hole 31. The suction cup 5 is connected to the negative pressure box 6 through the negative pressure hole 32, the lifting hole 31, and the negative pressure channel 7. The lower end of the suction cup 5 is provided with a baffle 33. The diameter of the baffle 33 is larger than that of the sliding hole 30 and smaller than that of the lifting hole 31. The baffle 33 is slidably disposed in the lifting hole 31. A support plate 34 is provided on the inner wall of the lifting hole 31. A return spring 35 is provided between the support plate 34 and the baffle 33. After the glass 46 is removed from the suction cup 5, the baffle 33 and the suction cup 5 are pushed to rise and return to their original positions under the action of the return spring 35. The side wall of the sliding hole 30 is re-sealed to prevent air leakage from the suction cup 5 and to adsorb impurities in the air into the negative pressure box 6.

[0037] It should be noted that the reset pushing force of the reset spring 35 is greater than the negative pressure adsorption force on the baffle 33. When the glass 46 is not placed on the suction cup 5, even if the negative pressure slot hole 4 moves to the position corresponding to the negative pressure box 6, the baffle 33 will still block the lower end of the sliding hole 30.

[0038] It should be noted that the support plate 34 should not completely block the lifting hole 31, so as to ensure that the negative pressure airflow enters the lifting hole 31 and the sliding hole 30 through the negative pressure channel 7. It should also be noted that the support plate 34 is made of a flexible material that can deform. When the negative pressure slot hole 4 rotates with the conveyor belt 3 to both ends, the deformation of the support plate 34 can adapt to the curvature of the conveyor rollers at both ends of the conveyor belt 3.

[0039] Specifically, see Figure 1 In this embodiment, two sets of centering adjustment mechanisms 36 are provided on both sides of the feeding end of the conveyor belt 3. The centering adjustment mechanism 36 includes: Side panel 37; The cylinder 38 is fixedly mounted on the side plate 37. The adjusting frame 39 is connected to the free end of the pushing cylinder 38, and the adjusting frame 39 has an adjusting groove 40 on the side near the conveyor belt 3; The guide roller 41 is rotatably mounted in the adjustment groove 40.

[0040] During operation, the adjustment frame 39 is moved by the action of the cylinder 38. The adjustment frames 39 of the two sets of central adjustment mechanisms 36 approach the glass 46 from both sides simultaneously, adjusting the position of the glass 46 to the middle of the conveyor belt 3. The glass 46 is stably transported between the four sets of grinding wheels 1 by the guide roller 41 in cooperation with the conveyor belt 3.

[0041] It should be noted that a guide rod is also provided on the side plate 37. The guide rod is connected to the adjustment frame 39. The guide rod can be an integral rod that is slidably set on the side plate 37, or it can be a sleeve and slide rod with telescopic function. The guide rod works with the push cylinder 38 to stably adjust the position of the adjustment frame 39.

[0042] Specifically, see Figure 3 In this embodiment, the support frame 10 is provided with an auxiliary pressing and fixing mechanism 43, which includes: The clamping cylinder 44 is fixedly mounted on the support frame 10; The pressing plate 45 is connected to the free end of the pressing cylinder 44. Under the action of the pressing cylinder 44, the pressing plate 45 moves downward and presses against the upper surface of the glass 46 to ensure the stability of the grinding wheel 1 when grinding the four sides of the glass 46.

[0043] Specifically, see Figure 7 , Figure 9 , Figure 13 and Figure 14 In this embodiment, a photoelectric sensor 42 is provided on the support frame 10. The photoelectric sensor 42 is located near the longitudinal screw 14, which is not equipped with a position adjustment component. The conveyor belt 3, the pressing cylinder 44, the lifting cylinder 23, the telescopic cylinder 28, the drive motor 11, and the edge grinding motor 25 are all electrically connected to the photoelectric sensor 42 through a controller.

[0044] During operation, the photoelectric sensor 42 monitors the conveying position of the glass 46. When one wide edge of the glass 46 is conveyed by the conveyor belt 3 to the area below the photoelectric sensor 42, it indicates that the glass 46 has been conveyed to the correct position. At this time, one wide edge of the glass 46 is exactly below the side of the grinding wheel 1 corresponding to a set of lifting cylinders 23 near the output end of the conveyor belt 3. Then, the controller controls the position adjustment component and the lifting cylinders 23 to move, so that the four sets of grinding wheels 1 contact the four sides of the glass 46 respectively. Under the action of the drive motor 11, the rotating grinding wheels 1 are driven to move relative to the four sides of the glass 46, and the four sets of grinding wheels 1 simultaneously grind the four sides of the glass 46.

[0045] The working principle of the glass edging machine provided in this embodiment is as follows: (1) Start the push cylinder 38. The push cylinder 38 drives the adjustment frame 39 to move closer to the glass 46. The distance between the guide rollers 41 of the two sets of central adjustment mechanisms 36 is adapted to the width of the glass 46.

[0046] (2) Place the glass 46 from the loading end of the conveyor belt 3 onto the suction cup 5 of the conveyor belt 3, and limit the position of the glass 46 on the conveyor belt 3 by the guide roller 41 to ensure that the glass 46 is placed in the center on the conveyor belt 3; under the gravity of the glass 46, press down the suction cup 5, the suction cup 5 moves down along the sliding hole 30, the suction cup 5 drives the baffle 33 to move down along the lifting hole 31, the baffle 33 moves away from the lower end of the sliding hole 30, and at the same time, the negative pressure hole 32 of the suction cup 5 slides out from the sliding hole 30 and is exposed in the lifting hole 31.

[0047] (3) The glass 46 is moved by the guide roller 41 through the conveyor belt 3. When the conveyor belt 3 moves the negative pressure slot 4 and the suction cup 5 to the negative pressure box 6, the suction cup 5 is connected to the inner cavity of the negative pressure box 6 through the negative pressure hole 32, the lifting hole 31 and the negative pressure channel 7. The negative pressure of the negative pressure pump 8 is applied to the glass 46 through the negative pressure box 6 and the suction cup 5 to ensure the stability of the glass 46 on the conveyor belt 3.

[0048] (4) When one wide edge of the glass 46 moves to below the photoelectric sensor 42, the photoelectric sensor 42 detects the glass 46, which means that the glass 46 has been delivered to the correct position. Under the action of the controller, the conveyor belt 3 stops rotating, the pressing cylinder 44 extends, and the pressing cylinder 44 drives the pressing plate 45 to press onto the glass 46, which, together with the suction cup 5, fixes the glass 46. Simultaneously, under the control of the controller, the lifting cylinder 23 drives the two sets of grinding wheels 1 corresponding to the longitudinal screw 14 to descend to a height suitable for the glass 46. The surface of the grinding wheel 1 corresponding to the set of longitudinal screws 14 near the output end of the conveyor belt 33 is exactly on the same plane as the wide edge of the glass 46. The controller controls the telescopic cylinder 28 to apply force to the load-bearing plate 29. The load-bearing plate 29 slides along the load-bearing slide groove 27. The load-bearing plate 29 drives the grinding wheel 1 to move through the mounting bracket 26, so that the other three grinding wheels 1 move to the same plane as the other three sides of the glass 46.

[0049] (5) Start the drive motor 11. The drive motor 11 drives a set of transverse screws 13 connected to it to rotate. Through the meshing of the first bevel gear 17 and the second bevel gear 19, the set of transverse screws 13 drives the transmission shaft 16 to rotate. Through the meshing of the first transmission gear 18 and the second transmission gear 20, the transmission shaft 16 drives the longitudinal screw 14 to rotate, realizing the simultaneous driving of the four sets of screws 12. The four sets of screws 12 drive the four sets of grinding wheels 1 to move relative to the side of the glass 46 through the corresponding drive plates 22. Under the driving action of the grinding motor 25, the grinding wheels 1 are driven to rotate. The four sets of rotating grinding wheels 1 complete the grinding of the four sides of the glass 46 at the same time during the driving movement of the screws 12, which improves the grinding efficiency of the glass 46. During this process, the moving speed of the drive plates 22 installed on the longitudinal screw 14 and the transverse screw 13 is related to the gear ratio of the first transmission gear 18 and the second transmission gear 20.

[0050] (6) After the glass 46 is ground on all four sides, the pressing cylinder 44, telescopic cylinder 28 and lifting cylinder 23 retract, and the corresponding grinding wheel 1 is reset. The conveyor belt 3 continues to transport the glass 46. After the glass 46 is moved away from the negative pressure box 6 along with the conveyor belt 3, due to the lack of negative pressure adsorption, the glass 46 can be easily removed from the suction cup 5 of the conveyor belt 3 at the discharge end of the conveyor belt 3.
