Description

Technical Field

[0001] This invention relates to the field of glass processing equipment, and more specifically, to a mixed-assembly edging mechanism and a four-sided edging machine. Background Technology

[0002] In glass processing, the sides of the glass need to be shaped to the required degree, such as a 45-degree chamfer on the top or bottom. This is typically done manually or semi-automatically. Manual edging mostly involves hand-held grinders to grind the glass sheet, and the protective film on the glass sheet must be manually removed before grinding. This method is labor-intensive, inefficient, and physically demanding. Semi-automatic edging requires grinding and trimming each of the four edges of the glass individually. It lacks automation and precision, and the glass needs to be flipped multiple times, which can easily scratch the glass and cause deviations in the grinding depth on each edge, resulting in low production efficiency and poor grinding quality.

Detailed Implementation

[0033] This invention discloses a hybrid edging mechanism. Through a combination of a flat grinding unit, a film removal unit, an upper 45-degree edging unit, and a lower 45-degree edging unit, it can perform side edging, remove the protective film from one side of the glass, perform 45-degree edging on the top and bottom of the side, effectively improving the processing efficiency of glass edging, film removal, and chamfering. It is highly practical. In this four-sided edging machine, the glass is conveyed by a conveying mechanism, passing sequentially through the front crossbeam, frame beam, and rear crossbeam. The hybrid edging mechanism in the above-mentioned structure processes the front, left and right sides, and rear of the glass plate, enabling separate edging, film removal, and chamfering of all four sides of the glass. It is flexible in use, highly automated, and the glass can be processed without rotation, greatly improving the efficiency and quality of edging.

[0034] The technical solutions of the embodiments of the present invention will be clearly and thoroughly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 16 The present invention provides a mixed-assembly edge grinding mechanism, including a connecting plate 1, wherein the connecting plate 1 is provided with at least one flat grinding unit 2, at least one film removal unit 3, at least one upper 45-degree edge grinding unit 4, and at least one lower 45-degree edge grinding unit 5; the flat grinding unit 2 is used to grind the outer side surface of the side of the glass 10; the film removal unit 3 is used to remove the protective film on the glass 10; the upper 45-degree edge grinding unit 4 is used to chamfer the top of the side of the glass 10 at a 45-degree angle; and the lower 45-degree edge grinding unit 5 is used to chamfer the bottom of the side of the glass 10 at a 45-degree angle.

[0036] In an embodiment of the present invention, a connecting plate 1 is mounted on a grinding machine. The grinding machine can be equipped with pushing or sliding devices, allowing the various functional devices on the connecting plate 1 to approach the glass 10 plate, thereby processing the side edges of the glass 10 plate. Specifically, the functional devices on the connecting plate 1 include at least one flat grinding unit 2, at least one film removal unit 3, at least one upper 45-degree grinding unit 4, and at least one lower 45-degree grinding unit 5. The specific number can be set according to the material of the glass 10 and the needs of the production process. In this embodiment, the flat grinding unit 2 is used to process the vertical surface of the side edges of the glass 10 to improve the flatness of the side edges of the glass 10 plate. During production, transportation, storage, and installation, the glass 10 is usually covered with a protective film to protect its surface from scratches. The protective film acts as an isolation layer, preventing sharp objects, tools, or other hard objects from directly rubbing against the surface of the glass 10, thereby avoiding scratches. Before processing, the protective film in the processing area needs to be removed to prevent the grinding depth from being inaccurate due to the presence of the protective film, which could affect the final size and shape accuracy of the glass 10. Therefore, this embodiment includes a film removal unit 3, which acts on the processing area of ​​the glass 10 to remove the protective film from that area. The upper 45-degree edge grinding unit 4 and the lower 45-degree edge grinding unit 5 act on the top and bottom of the glass 10 respectively, performing a 45-degree chamfering operation on the sides of the glass 10.

[0037] Through the above structural design, several commonly used functions in glass 10 processing, such as flat grinding, film removal, upper 45-degree edge grinding, and lower 45-degree edge grinding, are integrated onto the connecting plate 1. This enables rapid processing at the same workstation, eliminating the need for frequent equipment switching between different processes, significantly saving time and labor costs. It allows for one-stop processing of the sides of the glass 10, significantly improving production efficiency. Compared to using multiple separate devices for flat grinding, film removal, and chamfering, the multi-functional integrated structure of the mixed-assembly edge grinding mechanism in this embodiment effectively reduces the floor space occupied by the edge grinding equipment, making the layout of the glass 10 production line more compact and rational, and improving space utilization. The upper 45-degree edge grinding unit 4 and the lower 45-degree edge grinding unit 5 are integrated on the connecting plate 1 and work together to precisely control the chamfering dimensions of the top and bottom of the glass 10. It can accurately chamfer the top and bottom of the sides of the glass 10 at 45 degrees, ensuring consistent chamfering angles. This overcomes the problems of deviation and insufficient consistency that traditional equipment easily produces when processing at different workstations, and can well meet the requirements of high-precision processing.

[0038] Furthermore, with the structure of this embodiment, the number of each functional unit can be flexibly set according to different requirements such as the material, thickness, and size of the glass 10, so as to reduce the burden on the equipment, avoid long-term overload of the edging equipment, and help to extend the service life of the equipment. Moreover, all the processing steps required for one side of the glass 10 are completed on a single mechanism, which facilitates real-time monitoring and quality inspection of the processing quality of the glass 10 side during production, allowing for timely detection of problems in the processing process, such as tool wear and surface defects of the glass 10, thus helping to improve product quality.

[0039] Preferably, the flat grinding unit 2 includes a first motor 201, a first support frame 202, and a first transmission module 203. The first support frame 202 includes a first front plate 2021, which is perpendicular to the top surface of the glass 10. The first motor 201 and the first transmission module 203 are respectively disposed on both sides of the first front plate 2021. The output end of the first motor 201 is provided with a first driving pulley 204. One end of the first transmission module 203 is provided with a first driven pulley 205, and the other end is provided with a grinding wheel 206. The first driving pulley 204 and the first driven pulley 205 are connected by a first synchronous belt. In this embodiment, the flat grinding unit 2 adopts a belt drive structure. The first motor 201 drives the first driving pulley 204, which in turn drives the first driven pulley 205 via the first synchronous belt, enabling the first transmission module 203 to operate, thereby driving the grinding wheel 206 to work. The grinding wheel 206 can be a diamond grinding wheel, a resin-bonded diamond grinding wheel, or an electroplated grinding wheel, etc. In this embodiment, the first transmission module 203 includes a transmission shaft and a bushing. The bushing is mounted on the first front plate 2021, and the transmission shaft is rotatably mounted on the bushing. The first driven pulley 205 and the grinding wheel 206 are respectively mounted at both ends of the transmission shaft to realize the transmission of power.

[0040] Preferably, the film removal unit 3 includes a second support frame 301, on which a film removal cylinder 302 and a pair of parallel sliding columns 303 are mounted. Linear bearings 304 are mounted on the sliding columns 303, and a third support frame 305 is provided between the two linear bearings 304 and connected via the third support frame 305. The piston rod of the film removal cylinder 302 is connected to the third support frame 305. A second transmission module 306 is provided on the front of the third support frame 305, and a second motor 307 is provided on the back. The output end of the second motor 307 is... The second transmission module 306 has a second drive pulley 308, a second driven pulley 309 at one end and a film removal wheel 310 at the other end, and the second drive pulley 308 and the second driven pulley 309 are connected by a second synchronous belt; a pair of sliding columns 303 are respectively connected to the bottom of a support plate 311, and the support plate 311 is provided with a plurality of guide wheels 312, which are used to support the bottom surface of the glass 10; the second support frame 301 is also provided with a buffer cylinder 313, and the piston rod end of the buffer cylinder 313 is connected to the support plate 311. In this embodiment, the support plate 311 supports the guide wheel 312, the guide wheel 312 contacts the bottom surface of the glass 10 and supports the glass 10. The film removal cylinder 302 above the glass 10 drives the third support frame 305 to move downward. The film removal wheel 310 on the third support frame 305 moves downward and contacts the protective film on the surface of the glass 10. Under the action of the second motor 307, the film removal wheel 310 rotates and removes the protective film in contact with it.

[0041] Preferably, the upper 45-degree edge grinding unit 4 includes a third motor 401, a fourth support frame 402, a third transmission module 403, and a universal joint coupling 404; the fourth support frame 402 includes a second front plate 4021, the second front plate 4021 being perpendicular to the top surface of the glass 10; the third transmission module 403 is mounted on the second front plate 4021, and the axis of the third transmission module 403 is set at a 45-degree angle with the second front plate 4021; the output end of the third motor 401 is connected to one end of the universal joint coupling 404, and the other end of the universal joint coupling 404 is connected to the third transmission module 403; the third transmission module 403 is provided with an upper chamfering wheel 405.

[0042] In traditional direct-drive edge grinding devices, due to structural design or installation errors, the motor's output shaft may not guarantee the accuracy of the chamfer angle, resulting in a deviation between the machined chamfer angle and the designed angle. In this embodiment, by employing a universal joint coupling 404, a certain angular deviation exists between the output shaft of the third motor 401 and the third transmission module 403, ensuring that the power of the third motor 401 is smoothly transmitted to the third transmission module 403, thereby driving the upper chamfering wheel 405 to perform the edge grinding operation. This avoids problems such as reduced transmission efficiency, increased component wear, and even equipment damage caused by misalignment. This structural design also makes the layout and installation of the third motor 401 and the third transmission module 403 more convenient. In addition, during the edge grinding process of glass 10, the relative positions of the third motor 401 and the third transmission module 403 change slightly due to factors such as vibration and impact. The universal joint coupling 404 has a certain degree of flexibility and mobility, which can adapt to this dynamic position change, ensure the stability and reliability of power transmission, and enable the equipment to operate stably under complex working conditions.

[0043] Preferably, the lower 45-degree edge grinding unit 5 includes a fourth motor 501, a fifth support frame 502, and a fourth transmission module 503; the fifth support frame 502 includes a first base plate 5021, which is set at a 45-degree angle to the top surface of the glass 10; the fourth motor 501 and the fourth transmission module 503 are respectively mounted on the first base plate 5021; the output end of the fourth motor 501 is provided with a third driving pulley 504; one end of the fourth transmission module 503 is provided with a third driven pulley 505, and the other end is provided with a lower chamfering wheel 506; the third driving pulley 504 and the third driven pulley 505 are connected by a third synchronous belt 507. In this embodiment, the fourth motor 501 is installed inside the fifth support frame 502, so that the center of gravity of the entire device is relatively centered, resulting in good balance and stability during equipment operation and reducing vibration and shaking. The fourth transmission module 503 is located beside the fourth motor 501, and the two are connected by a third driving pulley 504, a third driven pulley 505, and a third synchronous belt 507. When the fourth motor 501 starts, the third driving pulley 504 drives the third driven pulley 505 to rotate via the third synchronous belt 507. The third driven pulley 505 acts on the fourth transmission module 503, which in turn drives the lower chamfered wheel 506 to rotate. In this embodiment, the first base plate 5021 and the top surface of the glass 10 are designed to form a 45-degree angle, which simplifies the installation of the fourth transmission module 503 and ensures that the lower chamfered wheel 506 can achieve a 45-degree chamfer without repeatedly measuring the installation position.

[0044] Preferably, the number of the flat grinding units is five, namely a first flat grinding unit for rough grinding of the glass, a second flat grinding unit for rough grinding of the glass, a third flat grinding unit for fine grinding of the glass, a fourth flat grinding unit for fine grinding of the glass, and a fifth flat grinding unit for polishing the glass. The grit number of the grinding wheels on the first, second, third, fourth, and fifth flat grinding units increases sequentially. The number of the upper 45-degree edge grinding units is two, namely a first upper 45-degree edge grinding unit for rough grinding of the glass and a second upper 45-degree edge grinding unit for polishing the glass.

The mesh count of the lower chamfering wheel on the first lower 45-degree edge grinding unit is less than the mesh count of the lower chamfering wheel on the second lower 45-degree edge grinding unit; the first lower 45-degree edge grinding unit, the second lower 45-degree edge grinding unit, the first upper 45-degree edge grinding unit, the second upper 45-degree edge grinding unit, the film removal unit, the first flat grinding unit, the second flat grinding unit, the third flat grinding unit, the fourth flat grinding unit, and the fifth flat grinding unit are arranged in sequence.

[0045] In this embodiment, please refer to Figure 1 ,from Figure 1 As you can see, the following units are arranged in sequence: the first lower 45-degree edge grinding unit, the second lower 45-degree edge grinding unit, the first upper 45-degree edge grinding unit, the second upper 45-degree edge grinding unit, the film removal unit, the first flat grinding unit, the second flat grinding unit, the third flat grinding unit, the fourth flat grinding unit, and the fifth flat grinding unit. The following section provides a detailed explanation of each unit in conjunction with the glass processing procedure:

[0046] As the entire mixed-assembly edging mechanism approaches the glass plate, the lower chamfering wheel of the first 45-degree edging unit performs a 45-degree coarse grinding on the lower edge of the glass. In this process, the chamfering wheel has a smaller grit count, resulting in a relatively rough surface, suitable for the coarse grinding stage to quickly trim the glass edge and ensure efficient removal of excess glass. After the first 45-degree edging, the glass then enters the second 45-degree edging unit. This unit further refines the lower edge of the glass. Compared to the first 45-degree edging unit, the second 45-degree edging unit uses a higher grit chamfering wheel to further refine the beveled surface, reduce surface roughness, and improve the flatness and smoothness of the bevel. During this process, the higher-grit chamfering wheel more precisely removes minor imperfections and uneven parts from the glass edge, resulting in a more accurate bevel angle and a smoother surface, meeting higher processing precision requirements.

[0047] After two 45-degree edge grinding operations on the lower edge, the glass is conveyed to the first upper 45-degree edge grinding unit. This unit operates similarly to the first lower 45-degree edge grinding unit, except that a lower-grit upper chamfering wheel grinds the upper edge of the glass at a 45-degree angle. After the first upper 45-degree edge grinding is completed, the glass enters the second upper 45-degree edge grinding unit. Similar to the second edge grinding process on the lower edge, this unit performs fine grinding on the upper edge of the glass. By using a higher-grit upper chamfering wheel, the upper edge bevel is finely trimmed, further improving the surface quality of the upper edge bevel and achieving higher standards in flatness, smoothness, and angular accuracy to meet product design and quality requirements.

[0048] During the glass edging process, some protective film or other impurities may remain on the glass surface. The function of the film removal unit is to remove these materials.

[0049] After the coating is removed, the glass enters the first surface grinding unit, where the edges are coarsely ground using low-grit grinding wheels. Following the first unit, the glass enters the second unit. This unit uses slightly higher-grit grinding wheels for further surface grinding of the glass edges. After the second unit, the glass enters the third unit. The third unit continues with even higher-grit grinding wheels for finer grinding of the glass edges. The fourth unit uses even higher-grit grinding wheels for deep, fine grinding of the glass edges. The grinding wheels used in this unit have a very fine grit, enabling extremely precise grinding of the glass edges. The fifth unit, the final surface grinding process, primarily performs a final polishing of the glass edges. Using even higher-grit grinding wheels, the glass edges achieve a near-mirror finish, while ensuring that the flatness and dimensional accuracy of the edges meet design requirements, satisfying the stringent quality requirements of high-end products.

In this embodiment, the flat grinding unit 2, film removal unit 3, upper 45-degree edge grinding unit 4, and lower 45-degree edge grinding unit 5 under the connecting plate 1 are each connected to a sliding adjustment mechanism, allowing each unit to slide freely and move forward and backward according to actual production needs. The following explanation uses the flat grinding unit 2 as an example: The flat grinding unit 2 and the connecting plate 1 are connected by a linear slide rail and a slider seat. Then, a propulsion cylinder is set on the connecting plate 1, and a propulsion seat is installed on the flat grinding unit 2. The propulsion cylinder acts on the propulsion seat to drive the flat grinding unit 2 to move, so as to achieve control of different processing depths.

The conveying mechanism 7 is used to convey the glass 10. The rear rubber roller assembly 9 is located at the rear end of the frame 6 and is used to press the glass 10 and send it outward. Four mixed-grinding mechanisms are provided, and the four mixed-grinding mechanisms grind the four edges of the glass 10 respectively.

[0052] In an embodiment of the present invention, the four-sided edging machine includes a frame 6, which supports various functional components. The front roller assembly 8 at the front end receives the glass 10 and guides it into a designated area according to its size. The rear roller assembly 9 at the rear end also guides and conveys the glass 10, pushing it outwards and unloading it. A conveying mechanism 7 connects the front roller assembly 8 and the rear roller assembly, transporting the glass 10 between them. The four-sided edging machine employs a mixed-grinding mechanism, which allows for flat grinding, film removal, and chamfering of one side of the glass 10. In this embodiment, the glass 10 processed by the four-sided edging machine is a conventional rectangular or square glass plate. The four-sided edging machine is equipped with four mixed-grinding mechanisms, each processing one of the four sides of the glass 10.

[0053] Specifically, one mixed-grinding mechanism is located next to the front roller assembly 8, one next to the rear roller assembly 9, and the remaining two are located on both sides of the conveying mechanism 7. This allows the glass 10 to be quickly edged during the conveying process. For example, when the front roller assembly 8 feeds the glass 10 in, the mixed-grinding mechanism located there processes the front edge of the glass 10. Then, the glass 10 enters the conveying mechanism 7, and the two mixed-grinding mechanisms on both sides of the conveying mechanism 7 process the left and right edges of the glass 10, respectively. Finally, when the glass 10 enters the rear roller assembly 9, the remaining mixed-grinding mechanism processes the rear edge of the glass 10, thereby achieving the edge grinding operation on all four sides of the glass 10.

A set of mixed-assembly edge-grinding mechanisms is provided on the front sliding device 604. Driven by the front sliding device 604, the mixed-assembly edge-grinding mechanisms can move back and forth along the length of the front crossbeam 601, processing the front edge of the glass 10 during the movement. The rear sliding device 605 adopts the same structure as the front sliding device 604 to drive the mixed-assembly edge-grinding mechanism located there to grind the rear edge of the glass 10. The left and right sides of the glass 10 are achieved through the frame beam 602. Specifically, the frame beam 602 is equipped with a left sliding device 606 and a right sliding device 607, which can slide back and forth on the frame beam 602 and can move towards or in opposite directions on the frame beam 602, so as to adjust the position of the mixed-assembly edge-grinding mechanism according to different sizes of glass 10. When the glass 10 enters the processing area of ​​the frame beam 602, the mixed-grinding mechanism on the left sliding device 606 and the right sliding device 607 approaches the left and right sides of the glass 10 respectively and performs the grinding operation on the glass 10.

[0057] In this embodiment, the fixed edge pressure roller assembly 804 is fixedly mounted on the conveyor table 801. It includes a support roller for supporting the glass 10 and a pressure roller for pressing down and maintaining the smooth conveying of the glass 10, so as to keep one side of the glass 10 stable. The other side of the glass 10 is handled by the movable edge pressure roller assembly 810. Specifically, the overall movement of the movable edge pressure roller assembly 810 is achieved by the front slide block 808. The front slide block 808 can move on the front slide rail 806, and the movement control of the front slide block 808 is achieved by the drive mechanism 809 driving the gear meshing rack 807.

The stop roller 8106 on the second base plate 8104 abuts against the side of the glass 10 and can push the glass 10 closer to the fixed edge pressure roller assembly 804. At the same time, the pressing cylinder 8107 located above the glass 10 moves, driving the pressing plate 8108 downward. The pressing roller 8110 on the pressing plate 8108 contacts the top surface of the glass 10 and presses the glass 10 steadily onto the conveying roller 803.
