Description

Technical Field

[0001] This invention relates to the field of tempered glass processing technology, specifically a trimming device for tempered glass production. Background Technology

[0002] Existing glass cutting devices typically use a rotating blade that contacts and rubs against the glass to cut it. However, in practical use, traditional cutting devices have the following main drawbacks:

[0003] First, the installation accuracy of the cutting wheel is difficult to guarantee. Most existing cutting wheels are directly mounted on the tool holder via pins. Due to the mechanical clearance, the cutting wheel is prone to radial runout or axial wobble during rotation and cutting. This instability causes deviations in the cutting trajectory, severely affecting the straightness and flatness of the cut edge. Second, the cutting resistance is high. During the cutting process, the cutting wheel and the glass surface mainly rely on friction for transmission. If the rotation of the cutting wheel is obstructed, it easily changes from rolling friction to sliding friction, increasing the cutting resistance and causing uneven propagation of microcracks, resulting in chipped edges or serrated defects when the glass is peeled off.

[0004] To address the aforementioned problems, a cutting device for tempered glass production is proposed. Summary of the Invention

[0011] Preferably, the connecting plate is provided with an inflation assembly for supplying air to the two air intake channels. The inflation assembly includes an air pump, a sealing sleeve, and a conduit. The air pump is mounted on the connecting plate, the sealing sleeve is fixed to the mounting base by a connecting rod, an annular groove is formed on the outer peripheral wall of the rotating shaft, and flow channels are symmetrically formed between the end wall of the annular groove and the slot. The annular groove is rotatably disposed inside the sealing sleeve, one end of the conduit is connected to the air pump, and the other end of the conduit passes through the sealing sleeve and is connected to the annular groove.

[0015] Compared with the prior art, the present invention provides a trimming device for tempered glass production, which has the following advantages:

[0016] 1. Multiple positioning blocks are synchronously extended radially by air pressure, and evenly abut against the side wall of the cutter wheel, forcibly eliminating the installation gap and ensuring that the cutter wheel always maintains a unique optimal working position when rotating and cutting. This effectively compensates for the deflection torque generated by unidirectional cutting, prevents lateral deviation, and greatly improves the straightness of the cutting trajectory and the flatness of the edge.

[0017] 2. By using a continuously inflated pressure valve to drive the fan blades and gear set to work together, the positioning block applies a continuous tangential auxiliary torsional force to the cutter wheel, reducing cutting resistance, preventing rotational friction from turning into sliding friction, ensuring continuous and uniform microcracks, avoiding chipping or serrated defects during glass peeling, and significantly improving the yield.

[0018] 3. The gas discharged from the exhaust port is blown out tangentially along the cutter wheel, promptly removing adhering glass fragments and preventing repeated rolling of fragments from damaging the cutting line. At the same time, the tangential airflow provides a small amount of auxiliary thrust, which works synergistically with the mechanical torsional force to further reduce rotational resistance and make the cutter wheel run more smoothly and steadily.

[0033] Reference Figure 1-8 The present invention provides a technical solution:

[0034] A tempered glass cutting device includes a processing table 11, a cutting mechanism 2, and a torsion positioning mechanism 3. Two first moving modules 12 are slidably mounted on both sides of the processing table 11. A horizontal plate 13 connects the two first moving modules 12, and a second moving module 14 is slidably mounted on the horizontal plate 13. The moving directions of the first moving modules 12 and the second moving modules 14 are perpendicular. The cutting mechanism 2 includes a blade holder 21, a positioning shaft 22, and a cutting wheel 23. The blade holder 21 is drivenly connected to the second moving module 14 for vertical displacement. The positioning shaft 22 passes through the bottom of the blade holder 21, and a mounting groove is formed in the center of the bottom of the blade holder 21. The cutting wheel 23 is located in the mounting groove and rotates on the positioning shaft 22 to perform rotary cutting of the glass. Two torsion positioning mechanisms 3 are symmetrically arranged, one-to-one corresponding to each other in the blade holder 21 on both sides of the cutting wheel 23, to apply a torsional force to the cutting wheel 23 after positioning it.

[0035] First, in the above scheme, an adsorption device is installed inside the processing table 11, and an adsorption hole 111 is opened on the upper surface of the processing table 11. When the glass on the surface of the processing table 11 is trimmed, the adsorption device generates negative pressure, and the glass can be firmly adsorbed on the processing table 11, avoiding the glass from shifting during the trimming process.

[0036] Secondly, a conveyor belt mechanism 112 is installed side by side on the upper surface of the processing table 11, which can transport the glass to the designated cutting position.

[0037] Based on the above solution, please refer to Figures 1 to 3 When glass needs to be trimmed, the positioning shaft 22 is used to install the cutting wheel 23 in the mounting groove. Then, the two torsion positioning mechanisms 3 start to work synchronously. First, the cutting wheel 23 in the mounting groove is centered and positioned. During the trimming process, the cutting wheel 23 always maintains a unique position. After the centering is completed, the torsion positioning mechanism 3 can provide continuous torsion force to the side wall of the cutting wheel 23 to assist the cutting wheel 23 in completing the rotational cutting.

[0038] It is evident that by using the two torsion positioning mechanisms 3, not only can the precise centering positioning of the cutter wheel 23 be achieved, effectively eliminating the shaking caused by the installation gap, and ensuring that the cutter wheel 23 always maintains the only optimal working position when it is rotating at high speed, thereby greatly improving the straightness and flatness of the cut edge; it can also reduce the cutting resistance between the cutter wheel 23 and the glass, so that the cutter wheel 23 is always in a rotating state and the crack remains uniform.

[0039] The cutter wheel 23 is made of diamond, which has sufficient hardness to prevent chipping and ensure a certain service life.

[0040] Each first moving module 12 includes a protective cover, a driving component, a gear, and a rack 121. The protective cover is provided with a dovetail groove, and a dovetail block is installed on the side wall of the processing table 11. The dovetail groove is slidably engaged with the dovetail block. The driving component is installed inside the protective cover. The gear is fixed to the output end of the driving component. The rack 121 is fixed on the side wall of the processing table 11 and meshes with the gear.

[0041] When the drive unit is activated, it drives the gear three to rotate. The gear three meshes with the rack 121, thereby causing the two protective covers to move the horizontal plate 13 in the length direction.

[0042] The second moving module 14 includes a second protective cover, a second driving component, a fourth gear, and a second rack 141. The second protective cover is provided with a second dovetail groove, and a second dovetail block is installed on the horizontal plate 13. The second dovetail groove is slidably engaged with the second dovetail block. The second driving component is installed inside the second protective cover. The fourth gear is fixed to the output end of the second driving component. The second rack 141 is fixed on the horizontal plate 13 and meshes with the fourth gear.

[0043] When the second drive unit is activated, it drives the fourth gear to rotate. The fourth gear engages with the second rack 141 for transmission. Therefore, the tool holder 21 can move at any position above the processing table 11 to cut the glass.

[0044] In this application, the bottom sides of the tool holder 21 are provided with air intake channels 211 and built-in grooves 212, and the air intake channels 211 and built-in grooves 212 are connected. Each torsional positioning mechanism 3 includes a positioning component. The positioning component includes a rotating cylinder 31, a positioning block 32, and a spring 33. The rotating cylinder 31 rotates on the inner wall of the built-in groove 212. Multiple guide grooves 311 are provided on the inner circumference of the rotating cylinder 31. Multiple positioning blocks 32 are arranged, and the multiple positioning blocks 32 slide one-to-one in the multiple guide grooves 311. The air intake channels 211 are connected to the multiple guide grooves 311. Multiple springs 33 are arranged, and each spring 33 is connected between the corresponding positioning block 32 and the end wall of the guide groove 311 in which it is located.

[0045] Based on the above solution, please refer to Figures 3 to 6When the cutter wheel 23 is in the mounting slot, gas is filled into the air intake channel 211, and the air pressure in the guide groove 311 increases accordingly. The air pressure in the guide groove 311 causes the positioning block 32 to move closer to the cutter wheel 23.

[0046] As can be seen, multiple positioning blocks 32 on both sides of the cutter wheel 23 extend radially from the inside of the rotating cylinder 31 under air pressure, and evenly abut against the side wall of the cutter wheel 23 in a circumferential direction, thereby forcibly pushing the cutter wheel 23 to the center position of the mounting groove and eliminating the installation gap. After the positioning blocks 32 contact the cutter wheel 23, the air pressure in the air inlet channel 211 is maintained at a stable pressure, and the positioning blocks 32 apply a constant and symmetrical radial clamping force to the cutter wheel 23, realizing the centered positioning of the cutter wheel 23 during the working process.

[0047] Moreover, the multiple positioning blocks 32 on both sides of the cutter wheel 23 can compensate for the deflection torque generated when the cutter wheel 23 cuts in one direction, preventing the cutter wheel 23 from shifting laterally during the cutting process, thereby further ensuring the straightness of the cutting trajectory and the neatness of the edge, and improving the yield and cutting quality.

[0048] For lifting, the material of the positioning block 32 near the cutter wheel 23 is configured as rubber to ensure that the positioning block 32 can drive the cutter wheel 23 to rotate by friction.

[0049] In this application, the bottom sides of the tool holder 21 are provided with through holes 213 and toothed grooves 214, and the through holes 213 connect the air intake channel 211 and the toothed grooves 214. Each torsion positioning mechanism 3 also includes a torsion assembly. The torsion assembly includes a pressure valve 41, a first gear 42, a second gear 43, a fan blade 44, and an exhaust port 45. The pressure valve 41 is installed in the through hole 213, the connecting part of the first gear 42 is rotatably engaged in the end wall of the toothed groove 214, the second gear 43 is keyed to the outer peripheral wall of the rotating cylinder 31, the first gear 42 meshes with the second gear 43, multiple fan blades 44 are arranged circumferentially, and multiple fan blades 44 are fixed on the extension shaft of the first gear 42 near the through hole 213, and the exhaust port 45 connects the toothed groove 214 and the mounting groove.

[0050] Based on the above solutions, please continue to refer to... Figures 3 to 6 When the cutter wheel 23 is centered by the positioning blocks 32 on both sides, the gas in the air intake channel 211 continues to be filled, and the continued filling will further increase the air pressure in the guide groove 311. The pressure valve 41 set in the through hole 213 automatically opens after the air pressure reaches the preset threshold. The gas enters the tooth groove 214 through the through hole 213. The airflow entering the tooth groove 214 blows towards the fan blade 44, driving the fan blade 44 to rotate around its axis. The fan blade 44 drives the gear 42 fixed to it to rotate. The gear 42 further drives the gear 43 meshing with it to decelerate and rotate. The gear 43 then drives the rotating cylinder 31 to rotate around its own axis. The circumferential rotation of the rotating cylinder 31 is converted into the tangential friction force of the positioning block 32 on the side wall of the cutter wheel 23, so that the positioning block 32 applies a continuous auxiliary torsional force to the cutter wheel 23.

[0051] As can be seen, through the design of the torsion component, after the cutter wheel 23 is centered, it can automatically start and continuously apply auxiliary torsional force: the tangential friction of the positioning blocks 32 on both sides against the side wall of the cutter wheel 23 reduces the cutting resistance between the cutter wheel 23 and the glass, making the cutter wheel 23 rotate more smoothly, preventing the rotational friction between the cutter wheel 23 and the glass from turning into sliding friction, avoiding leaving a discontinuous and uneven micro-crack on the glass surface, and ensuring that the cut glass can be neatly separated along the preset cutting line when peeling, without problems such as displacement, chipping, or serrated glass edges caused by uneven cracks.

[0052] It should be noted that the rotational speed of the drum 31 is the same as that of the cutter wheel 23 to avoid defects caused by sliding friction in the cutter wheel 23 due to different rotational speeds.

[0053] In addition, after the gas entering the tooth groove 214 completes the driving of the fan blade 44, it is discharged into the mounting groove through the exhaust hole 45 and escapes from the cutting contact area between the cutter wheel 23 and the glass. The escaped gas acts on the cutter wheel 23, which can blow away the glass fragments adhering to the cutter wheel 23, avoid the fragments from repeatedly rolling between the cutter wheel 23 and the glass, and ensure that the microcracks are continuous and uniform.

[0054] In some alternative implementations, the orientation of each vent 45 is aligned with the rotation direction of the cutter wheel 23.

[0055] Please see Figure 5 The gas escaping from the exhaust port 45 is blown out along the tangential direction of the cutter wheel 23. This not only blows away glass fragments on the surface of the cutter wheel 23 along the rotational tangential direction, but also provides a small amount of tangential auxiliary airflow in the rotational direction of the cutter wheel 23, further reducing the rotational resistance of the cutter wheel 23. This works in synergy with the auxiliary torsional force applied by the positioning block 32, making the rotation of the cutter wheel 23 more stable and smooth, thereby further improving the edge cutting quality and cutting efficiency.

[0056] In some alternative embodiments, the tool holder 21 is composed of two symmetrically arranged engaging parts, each engaging part having a threaded hole 215, and studs are detachably installed in the two threaded holes 215.

[0057] Based on the above scheme, combined with Figure 4 and Figure 5 Therefore, when machining the internal groove of the tool holder 21, the two engaging parts can be machined in the same plane first, which is much less difficult than drilling the integral tool holder 21.

[0058] Moreover, when installing the rotary drum 31, gear 42, pressure valve 41 and fan blade 44, these structural components can be directly snapped into the corresponding slots, the two engaging parts can be joined together, and then the stud can be installed. The two engaging parts are closed to form the tool holder 21, which makes it more convenient to install the tool holder 21 and its internal structure.

[0059] In some alternative embodiments, the tool holder 21 is connected to a steering assembly, which includes a connecting plate 51, a mounting base 52, a motor 53, and a rotating shaft 54. The connecting plate 51 is drivenly connected to the second moving module 14, the mounting base 52 is fixed on the connecting plate 51, the motor 53 is fixed to the bottom of the mounting base 52, and the rotating shaft 54 ​​is fixed to the output end of the motor 53. A slot is provided at the center of the bottom of the rotating shaft 54, and the tool holder 21 is detachably installed in the slot.

[0060] Please see Figure 7 When motor 53 starts, it drives the rotating shaft 54 ​​to rotate. The rotating shaft 54 ​​will drive the knife holder 21 in its slot to rotate, so that the cutter wheel 23 rotates with the knife holder 21 to completely cut the edge of the glass.

[0061] When installing the tool holder 21, first insert the two engaging parts into the slot, then insert the stud through the rotating shaft 54 ​​and assemble it with the two engaging parts.

[0062] In some alternative embodiments, the connecting plate 51 is provided with an inflation assembly for supplying air to the two air intake channels 211. The inflation assembly includes an air pump 61, a sealing sleeve 62, and a conduit 63. The air pump 61 is mounted on the connecting plate 51, the sealing sleeve 62 is fixed to the mounting base 52 by a connecting rod 64, an annular groove 641 is formed on the outer peripheral wall of the rotating shaft 54, and flow channels 642 are symmetrically formed between the end wall of the annular groove 641 and the slot. The annular groove 641 is rotatably disposed in the sealing sleeve 62, one end of the conduit 63 is connected to the air pump 61, and the other end of the conduit 63 passes through the sealing sleeve 62 and is connected to the annular groove 641.

[0063] Please see Figure 7 and Figure 8 When the air pump 61 starts, it fills the annular groove 641 with gas through the conduit 63. The airflow enters the intake channel 211 through the flow channel 642, causing the air pressure in the intake channel 211 to rise.

[0064] When the rotating shaft 54 ​​rotates, the flow channel 642 always remains connected to the guide tube 63. Therefore, no matter how the cutter wheel 23 rotates for cutting, the air pressure in the air intake channel 211 can increase after the air pump 61 is started.

[0065] In some alternative embodiments, a sleeve 71 is fixed on the outer peripheral wall of the rotating shaft 54, and two positioning wheels 72 are symmetrically rotated and engaged on the outer peripheral wall of the sleeve 71. The two positioning wheels 72 can ensure that the two sides of the glass in the cutting area are positioned when the cutter wheel 23 cuts the glass, so as to avoid the glass from shifting.

[0066] In a preferred embodiment, a transmission mechanism is provided between the connecting plate 51 and the second moving module 14. The transmission mechanism includes a guide plate 81, a second motor 82, a lead screw 83, a slider, and a limiting plate. The guide plate 81 is fixed to the second moving module 14, the second motor 82 is fixed to the top of the guide plate 81, the lead screw 83 is fixed to the output end of the second motor 82, the slider has a screw hole, the lead screw 83 is threaded into the screw hole, the connecting plate 51 is fixed to the slider, and two limiting plates are provided, with the slider sliding against the two limiting plates.

[0067] Please see Figure 2 When motor 82 starts, it drives lead screw 83 to rotate. Lead screw 83 drives slider to move in the vertical direction, and slider drives connecting plate 51 to move in the vertical direction. Therefore, the distance between cutter wheel 23 and glass is adjustable, and glass of different thicknesses can be cut.

[0068] In a preferred embodiment, the connecting plate 51 is also equipped with an infrared rangefinder 91, a data processor 92, and a control center 93. The infrared rangefinder 91 is used to detect the position and size of the glass, the data processor 92 is used to convert image signals into electrical signals, and the control center 93 is used to receive electrical signals and respond to the actuators. The input terminal of the control center 93 is electrically connected to the data processor 92. The output terminal of the control center 93 is connected to the first moving module 12, the second moving module 14, the first motor 53, the air pump 61, and the second motor 82 via electromagnetic wave signals.

[0069] A protective cover 10 is installed on the connecting plate 51 to protect the components installed on the connecting plate 51.

[0070] The working principle of this invention:

[0071] First, the glass to be cut is placed on the processing table 11. An infrared rangefinder 91 detects the glass's position and dimensions. The data processor 92 processes the signal and transmits it to the control center 93. The control center 93 controls the first moving module 12 and the second moving module 14 to move the cutter holder 21 to the cutting starting point. Simultaneously, it controls the second motor 82 to adjust the downward pressure of the cutter wheel 23 to match the glass thickness. The air pump 61 is started to inflate the air intake channel 211. The positioning block 32 extends to center the cutter wheel 23. Once the air pressure reaches the threshold, the pressure valve 41 opens, driving the fan blades 44 and gear set to rotate the drum 31, applying auxiliary torsional force to the cutter wheel 23. Then, the control center 93 controls the first motor 53 to rotate the cutter wheel 23. The first and second moving modules work together to drive the cutter wheel 23 to move and cut along the glass edge. The exhaust port 45 blows away debris. After cutting, all mechanisms reset, and the finished glass is removed.

[0072] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
