Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, and specifically relates to a dual-station glass waterjet cutting and polishing machine. Background Technology

[0002] In the glass processing industry, glass cutting and polishing are crucial processes that directly affect the quality and safety of glass products.

[0003] Existing cutting processes mostly use glass cutters or rotating blades, which are inefficient, energy-intensive, and prone to generating significant impact, leading to defects such as cracks and breakage. This is particularly problematic for high-precision, high-value glass products. Waterjet cutting, as a newer technology, effectively avoids the drawbacks of mechanical cutting, achieving high-precision cuts by using a high-pressure water jet. However, single waterjet cutting equipment has limited functionality and cannot perform post-cut edge polishing. The edges of cut glass are typically sharp and contain micro-cracks. Without polishing, these can pose safety hazards during subsequent use, such as scratching users. Furthermore, during tempering, these micro-cracks may cause the glass to shatter, severely impacting product quality. Currently, some polishing equipment on the market can only polish open edges of glass, offering poor polishing results for special areas such as the edges of cut glass holes, failing to meet the demands of high-quality glass processing. To address the need for grinding the edges of glass holes, existing technology describes a patent application (CN201810511591.7) entitled "An Automatic Glass Hole Grinding Machine." The document states that this invention discloses an automatic glass hole grinding machine, belonging to the field of glass processing technology. To solve the problem of existing grinding devices being extremely time-consuming and labor-intensive when grinding glass holes of different diameters in a single pass, this automatic glass hole grinding machine includes a first guide rail, a guide rail, a first drive wheel, a slider, a second drive wheel, a rotating motor, a main telescopic rod, an adjusting cylinder, a secondary telescopic rod, a drive block, a fixing plate, a second slider, a long connecting rod, a short connecting rod, a vertical rod, a friction block, a distance sensor, a glass placement rack, and a control module; it can greatly improve grinding efficiency.

[0004] This grinding device solves the problem of grinding the edges of glass holes, but it still has the following drawbacks in actual use:

[0005] 1. Both sides of the glass hole need to be polished, but the existing equipment can only polish one side.

[0006] 2. The grinding component of this equipment consists of two grinding blocks, and the distance between these two grinding blocks can be adjusted. Although this structure can adapt to different glass apertures, it is complex, requires frequent maintenance, and the symmetrically arranged grinding blocks can only grind the edge of the hole twice in one rotation, resulting in low grinding efficiency. Utility Model Content

[0007] The present invention aims to provide a dual-station glass waterjet cutting and polishing machine, which is mainly used to solve the technical problem that the existing technology can only polish glass holes on one side and has low polishing efficiency.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A dual-station glass waterjet cutting and polishing machine includes a machine tool. The machine tool has a cutting zone and a polishing zone arranged sequentially along the glass conveying direction. A waterjet cutting mechanism is installed in the cutting zone, and a polishing mechanism is installed in the polishing zone. The waterjet cutting mechanism includes a transverse sliding mechanism, a vertical sliding mechanism mounted on the transverse sliding mechanism, and a longitudinal electric slide rail mounted on the vertical sliding mechanism. A cutting machine is mounted on the longitudinal electric slide rail, and the cutting machine includes a waterjet nozzle for drilling holes in the glass. The polishing mechanism includes a longitudinal moving frame, with polishing components for grinding the edges of the glass holes symmetrically mounted on its upper and lower sides. A drive device for moving the longitudinal moving frame up and down is mounted on the longitudinal moving frame. The polishing components include a polishing motor mounted on the longitudinal moving frame, and a tapered polishing head with a vertically oriented axis is mounted at the output end of the polishing motor. The machine tool also includes a conveying device for conveying the glass.

[0010] In this solution, after the glass is fed into the machine tool, it enters the cutting area. Then, the water jet nozzles of the water-jet cutting mechanism spray high-pressure water jets, which, driven by the horizontal and vertical sliding mechanisms, cut the glass along a preset trajectory, creating a hole. After cutting, the glass enters the grinding area under the drive of the conveying device. In the grinding area, the drive device moves the longitudinal moving frame up and down to grind the upper and lower edges of the glass hole, preventing the glass from cracking during tempering. In this solution, the conical grinding head is inserted into the glass hole coaxially. During rotation, it can chamfer and grind the edges of the glass hole. Furthermore, driven by the drive device, the symmetrical conical grinding heads on both sides of the longitudinal moving frame grind the upper and lower edges of the glass hole sequentially. This solution has the following beneficial effects:

[0011] 1. The advantage of the conical grinding head is that it can adapt to grinding glass holes of different diameters, and as the longitudinal moving frame moves up and down, it can grind both the upper and lower edges of the glass hole; at the same time, the conical grinding head fits perfectly with the edge of the glass hole, and can grind the edge of the glass hole multiple times in one rotation. Compared with the existing technology that only uses two grinding blocks for grinding, this solution has a higher grinding efficiency per unit time.

[0012] 2. During the grinding process, in order to prevent local overheating of the glass and changes in the internal stress of the material, and to prevent dust from being dispersed in the air and affecting the processing environment, it is usually necessary to spray water on the grinding area. However, in this solution, the glass is ground immediately after water cutting, and the water remaining on the glass surface can cool the glass. Furthermore, based on the purpose of grinding the glass holes, there is no need to perform long-term fine grinding on the glass holes. Therefore, no additional water spraying is required during the grinding process, saving processing water.

[0013] In summary, this solution solves the technical problem of existing technologies that can only grind glass holes on one side and have low grinding efficiency.

[0014] Preferably, the conveying device includes conveying rollers mounted on the machine tool and located between and on both sides of the cutting and grinding areas; wherein a plurality of the conveying rollers are equipped with drive motors at their ends. In this embodiment, the drive motors drive the conveying rollers to rotate, thereby providing driving force for glass conveying.

[0015] Preferably, the conveying device further includes conveyor belt assemblies installed in the cutting and polishing areas. The conveyor belt assembly comprises two conveyor belt devices respectively installed on both sides of the machine tool interior. In this design, since no conveyor rollers are installed in the cutting and polishing areas, conveyor belt assemblies are installed in these two areas. The conveyor belt assemblies are located at the edges of the areas, thus not affecting glass processing, while simultaneously providing power for glass conveying and ensuring the glass safely crosses these two areas.

[0016] Preferably, the device further includes a clamping device for pressing the glass downwards. There are at least four clamping devices, two of which are respectively located on both sides of the cutting area, and the other two are respectively located on both sides of the grinding area. Each clamping device includes a mounting frame fixed to the outer surface of the machine tool. A clamping cylinder with its output end pointing downwards is mounted on the mounting frame facing the top surface of the glass. A clamping plate is fixed to the output end of the clamping cylinder. In this solution, to reduce glass vibration during cutting or grinding, which could lead to a decrease in cutting or grinding accuracy, a clamping device is provided to ensure the stability of the glass during the cutting or grinding process.

[0017] Preferably, a protective plate is provided in the cutting area below the cutting water nozzle. A support frame is fixed to the upper surface of the protective plate, and a drain outlet is provided at the bottom of the side wall of the support frame. In this design, the protective plate is made of high-strength material to block the high-pressure water jet and prevent the bottom of the machine tool from being damaged by the water jet; the support frame can provide a certain reverse support force to the bottom surface of the glass to prevent the glass from breaking during the cutting process; the drain outlet is used to drain the water accumulated in the space formed by the support frame and the base plate.

[0018] Preferably, a collection box with an opening at the top is fixed inside the machine tool, located below the protective plate. The area of ​​the protective plate is smaller than the opening area of ​​the collection box, and it is fixed inside the collection box. In this solution, the collection box is used to collect wastewater generated during cutting.

[0019] Preferably, the upper surface of the support frame is covered with a rubber layer for shock absorption. In this design, the rubber pad dampens vibrations and prevents the glass from shattering due to rigid contact with the support frame.

[0020] Preferably, a filter cloth is installed in the middle of the collection box, and a drain pipe is connected to the bottom of the collection box. The wastewater filtered by the filter cloth is discharged from the drain pipe; this is used to separate glass shards from the water and reduce the cost of subsequent wastewater treatment.

[0021] Preferably, the machine tool has sliding grooves on both sides located in the grinding area, and the longitudinal moving frame passes through the sliding grooves and can move up and down within the sliding grooves; the driving device includes support platforms on both sides of the machine tool, and vertically arranged lifting cylinders are fixed on the support platforms. A connecting plate is fixed to the output end of the lifting cylinder, and the connecting plate is fixedly connected to the longitudinal moving frame. The extension and retraction of the lifting cylinders drives the longitudinal moving frame to move up and down.

[0022] Preferably, the machine tool is also equipped with two sets of limiting mechanisms. These two sets of limiting mechanisms are respectively installed at the front end of the cutting and grinding areas to position the glass within the cutting or grinding areas. Each limiting mechanism includes two symmetrically arranged stop mechanisms on both sides of the machine tool. Each stop mechanism includes a mounting bracket installed on the outside of the machine tool. An electric push rod is fixed inside the mounting bracket, and a baffle is fixed to the end of the electric push rod away from the mounting bracket. A slot is provided on the side wall of the machine tool, and the baffle can be inserted into the slot to stop the front end of the glass. In this solution, the baffle passes through the slot and its end enters the machine tool under the push of the electric push rod. When the glass is transferred to the processing position in the cutting or grinding area, its front end abuts against the surface of the baffle and cannot continue moving forward. After the glass sheets from both stations are transported to the fixed position, the conveying device stops conveying. At this time, the clamping device works, clamping the glass surface in the corresponding area. The waterjet cutting mechanism and the grinding mechanism begin to work, performing hole processing on the glass. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0035] like Figure 1 As shown, this dual-station glass cutting and polishing machine includes a machine tool 11, on which a cutting zone and a polishing zone are sequentially arranged along the glass conveying direction. A water jet cutting mechanism is installed in the cutting zone and a polishing mechanism is installed in the polishing zone on the machine tool 11. The machine tool 11 is also equipped with a conveying device for conveying glass.

[0036] After the glass is fed into the machine tool 11, it first enters the cutting area. The waterjet cutting mechanism includes a horizontal sliding mechanism 31, on which a vertical sliding mechanism 32 is installed. A longitudinal electric slide rail is installed on the vertical sliding mechanism 32, and a cutting machine 33 is installed on the longitudinal electric slide rail. The longitudinal electric slide rail drives the cutting machine 33 to move up and down. The cutting water jet of the cutting machine 33 sprays a high-pressure water jet, which, driven by the horizontal and vertical sliding mechanisms 32, performs waterjet cutting and drilling on the glass according to a preset trajectory. It should be noted that the horizontal and vertical sliding mechanisms 32 can be selected from existing lead screw guide mechanisms to precisely control the cutting path of the cutting machine 33.

[0037] like Figure 2 , Figure 3 As shown, a protective plate 41 is installed below the cutting water nozzle in the cutting area. The protective plate 41 is made of high-strength material to block the high-pressure water jet and prevent the bottom of the machine tool 11 from being damaged by the water jet. A support frame 42 is fixed to the upper surface of the protective plate 41. A drain port 43 is opened at the bottom of the side wall of the support frame 42 to drain the water accumulated in the space formed by the support frame 42 and the bottom plate. A rubber layer is attached to the upper surface of the support frame 42 to play a shock-absorbing role and prevent the glass from rigidly contacting the support frame 42 and cracking under cutting vibration. Inside the machine tool 11, below the protective plate 41, there is a collection box 46 fixed to the machine tool 1 with an open top. The area of ​​the protective plate 41 is smaller than the opening area of ​​the collection box 46 and it is fixed inside the collection box 46. The collection box 46 is used to collect the wastewater generated by cutting. A filter cloth 45 is installed in the middle of the collection box 46 to separate glass shards in the water and reduce the cost of subsequent wastewater treatment. The bottom of the collection box 46 is connected to a drain pipe 44 for discharging wastewater.

[0038] like Figure 1 , Figure 3 As shown, after cutting, the glass enters the polishing area under the drive of the conveying device. The conveying device includes several conveying rollers 12 installed on the machine tool 11 and located between and on both sides of the cutting and polishing areas. Some of the conveying rollers 12 are equipped with a drive motor 121 at one end, which drives the conveying rollers 12 to rotate, thereby providing driving force for glass conveying. In addition, a conveyor belt assembly is also installed in the cutting and polishing areas. The conveyor belt assembly includes two conveyor belt devices 13 installed on both sides of the machine tool 11. It should be noted that since these two areas need to be processed, there should be no obstruction in the middle. Therefore, the conveyor belt assembly is located at the edge of the area, and the conveying direction is consistent with the conveying direction of the conveying rollers 12. This does not affect the glass processing, but provides power for glass conveying and ensures that the glass safely crosses the area.

[0039] like Figure 1 , Figure 4 As shown, the grinding mechanism includes a longitudinal moving frame 52. Slots 53 are provided on both sides of the machine tool 11 at the grinding area. The longitudinal moving frame 52 passes through the slots 53 and can move up and down within them. Grinding components for grinding the edges of glass holes are symmetrically installed on the upper and lower sides of the longitudinal moving frame 52. The installation position of the grinding components on the longitudinal moving frame 52 can be adjusted according to the number and spacing of the glass holes being processed. A driving device is installed on the longitudinal moving frame 52 to drive its up and down movement. The driving device drives the longitudinal moving frame 52 to move up and down. The symmetrical grinding components on the upper and lower sides of the longitudinal moving frame 52 grind the edges of the glass holes sequentially to prevent the glass from cracking during tempering.

[0040] The polishing assembly includes a polishing motor 54 mounted on a longitudinal moving frame 52. A conical polishing head 55 with its axis vertically aligned is mounted on the output end of the polishing motor 54. The conical polishing head 55 is coaxially aligned with the glass hole. When inserted into the glass hole and rotated, it performs chamfering polishing on the edge of the glass hole. The conical polishing heads 55, which are symmetrical on the upper and lower sides of the longitudinal moving frame 52, polish the upper and lower edges of the glass hole in turn under the drive of the drive device.

[0041] The drive unit includes support platforms on both sides of the machine tool 11. Vertically arranged push cylinders 51 are fixed on the support platforms. A connecting plate is fixed to the output end of the push cylinder 51. The connecting plate is fixedly connected to the side of the longitudinal moving frame 52. The longitudinal moving frame 52 is moved up and down by the extension and retraction of the push cylinder 51.

[0042] like Figure 1 As shown, to reduce the impact of glass vibration on accuracy during cutting or grinding, four clamping devices are installed. Two clamping devices are located on both sides of the cutting area, and the other two are located on both sides of the grinding area. The clamping device includes a fixed frame 21 fixed to the outer surface of the machine tool 11. A clamping cylinder 22 with its output end pointing downward is installed on the fixed frame 21. A clamping plate is fixed to the output end of the clamping cylinder 22 to press the glass downward, ensuring the stability of the glass during cutting or grinding.

[0043] like Figure 5 , Figure 6 As shown, the machine tool is also equipped with two sets of limiting mechanisms. The two sets of limiting mechanisms are respectively installed at the front end of the cutting area and the grinding area to position the glass in the cutting area or the grinding area. One set of limiting mechanisms includes two stop mechanisms symmetrically arranged on both sides of the machine tool 11. The stop mechanism includes a mounting bracket 61 installed on the outside of the machine tool 11. An electric push rod 62 is fixed inside the mounting bracket 61. A baffle 63 is fixed at the end of the electric push rod 62 away from the mounting bracket 61. A slot is opened on the side wall of the machine tool 11 and the baffle 63 can be inserted into the slot to stop the front end of the glass.

[0044] Furthermore, the dual-station glass cutting and polishing machine also includes a controller, which is electrically connected to a vision sensor. The drive motor 121, polishing motor 54, clamping cylinder 22, and pushing cylinder 51 are all electrically connected to the controller and participate in the control of each mechanism in the dual-station glass cutting and polishing machine.

[0045] In use, un-drilled glass is fed into the machine tool 11 by machine or manually. The vision sensor detects that the glass sheet is placed on the machine tool and sends a signal to the controller. The controller controls the limiting mechanism located at the front end of the cutting area to push the baffle 63 into the machine tool 11. With the cooperation of multiple conveying rollers 12, the glass enters the cutting area and the front end abuts against the baffle 63, thus preventing it from moving forward. The vision sensor recognizes that the glass no longer moves, so it controls all conveying devices to stop moving. Then, it controls the pressing devices on both sides of the cutting area to press the glass surface. At this time, the horizontal and vertical sliding mechanisms 32 move synchronously, driving the cutting machine 33 to cut the glass hole.

[0046] After cutting is completed and there is no glass being processed in the polishing area, the controller controls the clamping device to lift, the baffle 63 to retract, and the conveying device to move, transporting the perforated glass to the polishing area.

[0047] When the vision sensor detects that glass has entered the polishing area, the controller controls the baffle 63 at the front end of the polishing area to pop out in advance until the front end of the glass is blocked by the baffle 63 and cannot move. Then, the pressing device located at the front and rear of the polishing area presses down on the glass. Then the polishing mechanism of the polishing area starts to work. Specifically, the push cylinder 51 is started to drive the longitudinal moving frame 52 to move up and down, which drives the upper and lower two conical polishing heads 55 to insert into the glass hole to polish the edge of the glass hole.

[0048] New glass can only enter the cutting area for cutting when the grinding mechanism starts working; after the grinding area finishes its work, all the clamping devices on both sides of the grinding area are lifted, the baffle 63 of the grinding area retracts, and the conveying device carries the glass away from the grinding area. Only after the glass in the cutting area has finished its water cutting process can it enter the grinding area for grinding.

[0049] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention.
