Technical Field

[0001] This utility model relates to the field of glass production technology, specifically to a cutting device for substrate glass edge material. Background Technology

[0002] In the field of LCD substrate glass manufacturing, the rapid production line for semi-finished substrate glass is the core link connecting the annealing furnace and the finished product warehouse. It is mainly used to quickly and automatically process the independent semi-finished glass sheets formed by cutting and breaking the continuous glass strips at the exit of the annealing furnace. In order to optimize the production layout of substrate glass and improve the cycle time, a substrate glass edge cutting device is needed.

[0003] The prior art patent document CN214299882U discloses a breaking device for a glass substrate cutting machine, including a cutting machine body, a control box bolted to the bottom of the cutting machine body, a controller bolted to the right side of the control box, an adjustment mechanism provided in the inner cavity of the control box, and through slots sequentially opened on both sides of the top of the control box from front to back, with a lifting column slidably connected to the inner cavity of the through slots via a collar. This invention uses a push rod cylinder to provide the driving source. Through the cooperation of a first sliding sleeve and a first sliding column, the movable rod can move the moving seat. Through the cooperation of a connecting plate and a pulley, the moving seat can adjust the height of the lifting column. Through the cooperation of a first spring, the lifting column can provide elastic rebound, thereby fixing the glass substrate with the lifting column, preventing the glass substrate from shifting, and enhancing the fixing effect of the glass substrate.

[0004] Although the existing technology has many advantages, the following problems still exist: During the use of the device, the glass is laid flat on the top of the control box, which makes it difficult to form a torque, making it difficult for the breaking mechanism to apply force to break the material, and the processing of the substrate glass is not convenient; secondly, the cut edge material stays on the top of the control box during the use of the device, which is not convenient to clean and affects subsequent glass cutting, and needs to be improved. In view of this, we propose a cutting device for substrate glass edge material. Utility Model Content

[0006] 1. Technical problems to be solved:

The magnetic drive conveying device, the slitting machine, the first motor, and the first motor are electrically connected to an external power source, and the vacuum suction cup is connected to an external vacuum pump pipeline. In addition to protecting the substrate glass, the elastic properties of the pressure rollers also facilitate deformation. When one pressure roller is lifting and breaking the material, the other pressure roller will not be unable to lift due to its inability to rotate.

[0012] In a preferred embodiment of this utility model for a substrate glass edge cutting device, the cleaning assembly includes a second motor. The output end of the second motor is equipped with a lead screw. Slider blocks are threaded to both ends of the lead screw's outer circumference.

Dust covers are provided at one end of each of the two slider side walls. The second motor is electrically connected to an external power source. Protrusions are provided on both sides of the top of the waste hoppers to prevent glass edge material from slipping and affecting collection.

[0013] In a preferred embodiment of the present invention, a cutting device for substrate glass edge material is provided, wherein the first gear has more teeth than the second gear, and the pressure roller is made of high-performance engineering polyurethane.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of substrate glass edge cutting device uses a first motor to drive the first gear to rotate, which causes the meshing second gear to rotate synchronously. This makes it easy for two rotating rods to drive the pressure rollers to rotate. One pressure roller lifts the substrate glass from the bottom up to break it, while the other pressure roller presses the substrate glass from the top down to prevent the glass from shifting. This makes the glass more stable when breaking the edge material and facilitates the formation of torque, making the glass breaking process more convenient.

[0021] This type of device for cutting edge material of substrate glass uses a second motor to drive a lead screw to rotate, causing two sliders to move two cleaning plates in opposite directions synchronously. This facilitates the cleaning of the cut edge material into a waste hopper for collection, preventing residue from affecting subsequent glass cutting. Attached Figure Description

[0034] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0035] This utility model provides an overall structural schematic diagram of an embodiment of a substrate glass edge cutting device, including:

[0036] Please see Figures 1-6This embodiment of a substrate glass edge cutting device includes a magnetic drive conveying device 1. A longitudinal cutter 2 is threadedly connected to one side of the magnetic drive conveying device 1. The longitudinal cutter 2 is used to precisely cut grooves on the glass surface for easy subsequent breaking. A carrier fixture plate 3 is slidably connected to the top of the magnetic drive conveying device 1. The carrier fixture plate 3 is used to balance with the magnetic drive conveying device 1 for stable linear movement under magnetic drive. A mounting platform 4 is welded to one side of the top of the carrier fixture plate 3. A vacuum suction cup 5 is embedded in the top of the mounting platform 4. The vacuum suction cup 5 is used to hold the substrate glass edge material. The glass plate is firmly and securely fixed without damage. A material-bending assembly 6 is welded to the side wall of the mounting platform 4. The material-bending assembly 6 includes multiple mounting blocks 601. A fixing frame 602 is welded to the other side of each mounting block 601. The fixing frame 602 protects the internal first gear 605 and second gear 606 from external impurities affecting their meshing. A first motor 603 is threadedly connected to the side wall of the fixing frame 602. The output end of the first motor 603 is connected to a rotating shaft 604 via a coupling. The first motor 603 drives the rotating shaft 604 to rotate and drive the first gear 605. 05. A rotating shaft 604 has a first gear 605 that is interference-fitted to its outer circumference. The first gear 605 meshes with a second gear 606. The second gear 606 is used to synchronize the rotation of the first gear 605, causing the other rotating shaft 604 to rotate. The inner circumference of the second gear 606 is also interference-fitted with another rotating shaft 604. Both ends of the outer circumference of the two rotating shafts 604 are welded with connecting plates 607. The two rotating shafts 604 are used to drive the connecting plates 607 at both ends to rotate synchronously. The other end of the inner wall of the connecting plate 607 is rotatably connected to a rotating shaft. The rod 608 has an interference fit with a pressure roller 609 on its outer circumference. The two pressure rollers 609 are used to lift one side of the bottom of the glass and press the top of the glass to form a torque, which facilitates the breaking of the material. The bottom of the side wall of the mounting platform 4 is threaded with a cleaning component 7. The magnetic drive conveyor 1, the longitudinal cutter 2, and the first motor 603 are electrically connected to an external power supply. The vacuum suction cup 5 is connected to an external vacuum pump pipeline. The magnetic drive conveyor 1 is existing technology and can be directly referred to in patent number CN220139406U. It will not be described in detail here.

[0037] In some embodiments, the longitudinal slitting machine 2 includes a frame, a guiding mechanism, a cutting mechanism, a clamping mechanism, a dust extraction mechanism, a bottom transfer mechanism, and a maintenance platform. Since the bottom transfer mechanism is servo-driven, the cutting width can be adjusted within a certain size range to achieve cutting of any specification. The overall operation flow is as follows: the glass enters the longitudinal slitting machine 2 through vertical conveying with the help of the guiding mechanism. Then, the front clamping mechanism and the back clamping mechanism operate simultaneously to clamp the glass. The clamping mechanism is driven by a servo-driven electric cylinder. After the glass is clamped, the cutting mechanism's blade extends to press the glass. After applying pressure, it starts cutting. After cutting, the cutting mechanism and the clamping mechanism are completely released. The robotic arm grabs the substrate glass onto the mounting platform 4 on top of the magnetic drive conveying device 1. The substrate glass is conveyed downstream. Throughout the entire operation, the dust extraction mechanism works continuously to remove particles generated during cutting. This operation is repeated. At the same time, personnel will periodically work on the maintenance platform to perform maintenance and inspection on the equipment.

[0038] It is worth noting that, in order to facilitate the cleaning of the cut edge material, the cleaning component 7 specifically includes a second motor 701. The output end of the second motor 701 is connected to a lead screw 702 via a coupling. Both ends of the outer circumference of the lead screw 702 are threadedly connected to sliders 703. The second motor 701 is used to drive the lead screw 702 to rotate, so that the two sliders 703 move synchronously in opposite directions. A cleaning plate 704 is welded to one side of each of the two sliders 703. The cleaning plate 704 is used to move and scrape off the cut glass edge material when the sliders 703 move. Waste hoppers 705 are welded to both side walls of the magnetic drive conveyor 1. The waste hoppers 705 are used to collect glass edge material. A dust cover 706 is glued to one end of the side wall of each of the two sliders 703. The dust cover 706 is used to prevent glass shards and other contaminants from jamming the threads of the lead screw 702, ensuring long-term reliable operation of the threaded transmission in a clean environment. The second motor 701 is electrically connected to an external power source.

[0039] Next, to avoid damaging the substrate glass, specifically, the first gear 605 has more teeth than the second gear 606, and the pressure roller 609 is made of high-performance engineering polyurethane. By making the first gear 605 have more teeth than the second gear 606, it is convenient for the other pressure roller 609, which is responsible for pressing, to rotate at a larger angle when the lifting pressure roller 609 rotates at a smaller angle. This facilitates the adjustment of the height of the other pressure roller 609 to avoid obstructing the placement of the substrate glass. The pressure roller 609 made of high-performance engineering polyurethane ensures the necessary friction when in contact with the glass, while avoiding damage or scratches to the glass surface.

[0040] Meanwhile, to improve the waste cleaning effect, specifically, the cross-sections of the two cleaning plates 704 are right-angled triangles facing opposite directions, and the dust cover 706 is made of high-strength polyester fiber cloth. The right-angled triangles facing opposite directions make it easy for the two cleaning plates 704 to fit together and form a shape with the pointed ends facing upwards, so that the cut edge material can slide down the slopes on both sides under the action of gravity, which is convenient for subsequent shoveling and cleaning. The dust cover 706, made of high-strength polyester fiber cloth through folding, has excellent wear resistance and tear resistance while ensuring flexibility and sealing.

[0041] Furthermore, to facilitate the movement of the slider 703, specifically, the threads at both ends of the outer circumference of the lead screw 702 are in opposite directions, and the slider 703 is slidably connected to multiple limiting rods 707 located on the inner wall of the mounting platform 4. Through the threads at both ends, it is easy to synchronously drive the two sliders 703 to make symmetrical linear movements when the lead screw 702 rotates. The structure is compact and the control synchronization is high. The limiting rods 707 effectively constrain the movement trajectory of the slider 703, preventing it from rotating with the lead screw 702, and ensuring the stability of the linear operation of the cleaning plate 704.

[0042] It is worth noting that, in order to make the substrate glass transport more stable, the magnetic drive transport device 1 has limit grooves 8 on both sides of the top, and the carrier tooling plate 3 has limit rails 9 welded on both sides of the bottom. The size and position of the limit grooves 8 match the size and position of the limit rails 9. The limit grooves 8, which match the size and position of the limit rails 9, can provide precise guidance and horizontal constraint for the carrier tooling plate 3, preventing it from deviating or overturning under magnetic drive, thus ensuring transport accuracy and stability.

[0043] Finally, to prevent the edge material from scattering, a limiting plate 10 is welded to the other side of the top of the carrier tooling plate 3. The position of the top of the waste hopper 705 matches the position of the top of the side wall of the carrier tooling plate 3. The limiting plate 10 helps to block the cutting edge material of the substrate glass, preventing the edge material from sliding to the top of the magnetic drive conveyor 1 and affecting the magnetic drive. The waste hopper 705, which matches the position of the top of the side wall of the carrier tooling plate 3, facilitates the precise guidance of the edge material to slide down for collection.

[0044] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0045] The device or equipment models mentioned in this article may be as follows:

[0046] First motor 603: SGM7J-0AAC6S;

[0047] Second motor 701: SGM7J-0AAC6S.

[0048] Combination Figures 1-6 The specific usage process of the substrate glass edge cutting device according to this embodiment is as follows:

[0049] 1: When this device is needed for cutting substrate glass edge material, place the substrate in the longitudinal cutter 2 and cut a groove at the required position on the glass edge. After completion, place the glass on the top of the mounting table 4, start the vacuum suction cup 5 to firmly adsorb and fix the glass, start the magnetic drive conveyor 1 to drive the carrier tooling plate 3 to carry the glass, turn on the first motor 603 to drive the rotating shaft 604 and the first gear 605 to rotate, the first gear 605 meshes to drive the second gear 606 and another rotating shaft 604 to rotate synchronously, the two rotating shafts 604 respectively drive the connecting plates 607 at both ends to rotate, the connecting plates 607 drive the rotating rod 608 and the pressure roller 609 to move, so that one pressure roller 609 lifts the bottom edge material area of ​​the glass, and the other pressure roller 609 presses down on the top of the glass. The two pressure rollers cooperate at the cutting groove to form a torque to break the edge material.

[0050] 2: After the glass is broken off, the magnetic drive conveyor 1 continues to drive the carrier tooling plate 3 to move to the top side of the waste hopper 705. The second motor 701 is turned on to make the lead screw 702 rotate and drive the two sliders 703 to move in opposite directions in sync. The two cleaning plates 704 move accordingly to scoop up the glass edge material that has fallen on the carrier tooling plate 3 and push it to the waste hopper 705 on one side for collection. During this process, the dust cover 706 attached to the side of the slider 703 moves with the slider to block the debris generated during cleaning and protect the threads of the lead screw 702.

[0051] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
