Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a positioning device for glass processing. Background Technology

[0002] Glass is an amorphous solid that can maintain a certain shape. It is a substance obtained by gradually cooling molten glass and gradually increasing its temperature. In today's society, glass has become ubiquitous in people's lives. Glass products can be seen everywhere, such as the glass cups we drink from, glass windows, glass doors, screen protectors on computer monitors, and glass buildings. The processing of glass after it is formed involves many steps, such as cutting, edge grinding, and drilling.

[0003] In the existing technology, the following shortcomings often exist in the edge grinding of round glass: positioning is difficult when placing round glass for processing, resulting in large positional errors, causing dimensional deviations in the glass processing or even damage to the glass. When facing the need to grind the edges of round glass of different sizes, it is necessary to frequently adjust the positioning device or even replace the equipment for processing. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a positioning device for glass processing, so as to solve the technical problem that it is difficult to position the round glass during processing, resulting in large position errors, causing deviations in glass processing dimensions or even damage to the glass, and that when facing the need to grind the edges of round glass of different sizes, it is necessary to frequently adjust the positioning device or even replace the equipment for processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for glass processing, comprising a platform, a second motor disposed at the bottom of the platform, a plurality of lead screws rotatably connected to the output end of the second motor, an L-shaped column threadedly connected to one end of each set of lead screws, a slider slidably connected inside each set of L-shaped columns, a telescopic wheel frame fixedly connected to one side of each set of sliders, a positioning wheel rotatably connected inside each set of telescopic wheel frames, and a fixed wheel frame fixedly connected to the lower surface of the upper end of each set of L-shaped columns, with a rubber wheel rotatably connected inside each set of fixed wheel frames, wherein a driving mechanism is fixedly connected to the top of both sets of L-shaped columns, a fixed wheel frame is fixedly connected to the inner side of each set of L-shaped columns, and a rubber wheel is rotatably connected to the bottom of the fixed wheel frame, wherein the rubber wheel rotates during glass processing through the drive mechanism.

[0006] By adopting the above technical solution, the second motor drives the large bevel gear to rotate and mesh with four sets of small bevel gears, thereby driving the four sets of lead screws to rotate and drive the four L-shaped columns to move towards the center at the same time. This allows the four sets of positioning wheels to quickly, accurately and stably position round glass of different diameters in the center. The two sets of drive devices drive two sets of opposing rubber wheels, so that the round glass can be evenly stressed and rotate at a constant speed, thus solving the technical problem of difficult positioning when placing round glass during processing.

[0007] Furthermore, a pneumatic telescopic frame is fixedly connected in the middle of the platform, and a suction cup device is rotatably connected to the top of the pneumatic telescopic frame. A spring is fixedly connected to the outer wall of each set of telescopic wheel frames, which plays a buffering role when the positioning wheel clamps the glass.

[0008] By adopting the above technical solution, the suction cup device is connected to an external air source to clamp the glass. At the same time, the pneumatic telescopic frame is connected to an external air source, which drives the suction cup device to rise and fall, thereby adjusting the height of the glass. When the U-shaped wheel surface of the positioning wheel contacts the edge of the glass, the four sets of positioning wheels adjust the position of the circular glass while clamping the circular glass. The spring installed on the telescopic wheel frame plays a role in protecting the glass and balancing the force while the positioning wheel clamps the glass.

[0009] Furthermore, the drive mechanism consists of a first motor, two sets of transmission wheels, and a transmission belt. The first motor is mounted on the top of the two sets of L-shaped columns, and a rotating shaft is fixedly connected to the inner side of the fixed wheel frame. The transmission wheel fixed at the output end of the first motor and the rotating shaft are connected by a transmission belt.

[0010] By adopting the above technical solution, the first motor drives the transmission wheel to rotate, thereby driving the lower transmission wheel to rotate through the transmission belt. At this time, the transmission wheel can drive the rubber wheel to rotate through the shaft, so that the circular glass can rotate at a uniform speed while being pressed by the four rubber wheels.

[0011] Furthermore, a bottom cover is fixedly connected to the bottom of the platform, and a second motor is fixedly connected to the lower end face of the bottom cover. The output end of the second motor passes through the bottom cover and is fixedly connected to a large bevel gear. The large bevel gear is rotatably connected to four sets of small bevel gears that do not interfere with each other. Each set of small bevel gears is fixedly connected to a lead screw, and the lead screw is rotatably connected to the inside of the platform.

[0012] By adopting the above technical solution, the second motor installed at the bottom of the platform drives the large bevel gear to rotate after being powered on. The large bevel gear meshes with four sets of small bevel gears that do not interfere with each other and rotates, thereby driving the four sets of lead screws to rotate. The lead screws drive the L-shaped columns to move in the slots opened in the platform through the threads, so that the four sets of L-shaped columns can move synchronously towards the center.

[0013] In summary, this utility model has the following beneficial effects: The utility model uses a second motor to drive a large bevel gear to mesh with four sets of small bevel gears, thereby driving four sets of lead screws to rotate and simultaneously move four L-shaped columns towards the center. This allows the four sets of positioning wheels to quickly, accurately, and stably position circular glass pieces of different diameters in the center. At this time, the glass is located at the bottom of the suction cup and is adsorbed and fixed. The pneumatic telescopic frame then lifts the glass, and the upper surface of the lifted glass contacts the four sets of rubber wheels. Two sets of drive devices drive two sets of opposing rubber wheels, allowing the circular glass to be evenly stressed and rotated at a constant speed for edge grinding. This solves the problem of difficult positioning when processing circular glass, which leads to large positional errors, causing dimensional deviations in glass processing or even damage to the glass. It also addresses the technical problem of frequently adjusting the positioning device or even replacing equipment when processing circular glass of different sizes. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] A positioning device for glass processing, as shown in Figures 1-4, includes a platform 1. A second motor 14 is provided at the bottom of the platform 1. The output end of the second motor 14 is rotatably connected to multiple sets of lead screws 4. One end of each set of lead screws 4 is threadedly connected to an L-shaped column 2. A slider 11 is slidably connected inside each set of L-shaped columns 2. A telescopic wheel frame 10 is fixedly connected to one side of each set of sliders 11. A positioning wheel 8 is rotatably connected inside each set of telescopic wheel frames 10.

[0022] When the second motor 14 is powered, it drives the four sets of lead screws 4 to rotate. The lead screws 4 drive the L-shaped columns 2 to move in the slots opened in the platform 1 through the threads. At this time, the four sets of L-shaped columns 2 can move synchronously towards the center.

[0023] Furthermore, each set of L-shaped columns 2 is fixedly connected to a fixed wheel frame 7 on the lower surface of the upper end, and a rubber wheel 5 is rotatably connected inside each set of fixed wheel frames 7. Both sets of L-shaped columns 2 are fixedly connected to a drive mechanism 3 at the top, and each set of L-shaped columns 2 is fixedly connected to a fixed wheel frame 7 on the inner side. The bottom of the fixed wheel frame 7 is rotatably connected to a rubber wheel 5. The rubber wheel 5 is driven by the drive mechanism 3 to rotate during glass processing.

[0024] The glass rises under the action of the pneumatic telescopic frame 15 and is pressed against the four rubber wheels 5. The four rubber wheels 5 ensure that the glass is subjected to uniform force, and at the same time, there is a large friction between the rubber wheels 5 and the glass. At this time, the two sets of mirror-mounted drive devices 3 are energized at the same time. The first motor 301 drives the transmission wheel to rotate, thereby driving the lower transmission wheel 302 to rotate through the transmission belt 303. At this time, the transmission wheel 302 can drive the rubber wheel 5 to rotate through the rotating shaft 6, so that the circular glass can rotate at a uniform speed while being pressed by the four rubber wheels 5.

[0025] Please see Figure 2 and Figure 3 A bottom cover 17 is fixedly connected to the bottom of the platform 1. A second motor 14 is fixedly connected to the lower end of the bottom cover 17. The output end of the second motor 14 passes through the bottom cover 17 and is fixedly connected to a large bevel gear 12. The large bevel gear 12 is rotatably connected to four sets of small bevel gears 13 that do not interfere with each other. A lead screw 4 is fixedly connected inside each set of small bevel gears 13. A pneumatic telescopic frame 15 is fixedly connected in the middle of the platform 1. A suction cup device 16 is rotatably connected to the top of the pneumatic telescopic frame 15. A spring 9 is fixedly connected to the outer wall of each set of telescopic wheel frames 10, which plays a buffering role when the positioning wheel 8 clamps the glass.

[0026] The suction cup device 16 is connected to an external air source to clamp the glass. At the same time, the pneumatic telescopic frame 15 is also connected to an external air source. The external air source drives the suction cup device 16 to rise and fall, thereby adjusting the height of the glass. After clamping the glass, the four positioning wheels 8 are passively raised, which drives the slider 11 to rise in the L-shaped column 2. After the second motor 14 installed at the bottom of the platform 1 is powered, it drives the large bevel gear 12 to rotate. The large bevel gear 12 meshes with four sets of small bevel gears 13 that do not interfere with each other and rotates, thereby driving the four sets of lead screws 4 to rotate. The lead screws 4 drive the L-shaped column 2 to move in the slot opened in the platform 1 through the thread. At this time, the four sets of L-shaped columns 2 can move synchronously towards the center.

[0027] Please see Figure 4 The drive mechanism 3 consists of a first motor 301, two sets of transmission wheels 302, and a transmission belt 303. The first motor 301 is installed on the top of the two sets of L-shaped columns 2, and a rotating shaft 6 is fixedly connected to the inner side of the fixed wheel frame 7. The transmission wheel 302 fixed at the output end of the first motor 301 and the rotating shaft 6 are connected by the transmission belt 303.

[0028] The first motor drives the transmission wheel 301 to rotate, which in turn drives the lower transmission wheel 302 to rotate via the transmission belt 303. At this time, the transmission wheel 302 can drive the rubber wheel 5 to rotate via the rotating shaft 6, so that the circular glass can rotate at a uniform speed while being pressed by the four rubber wheels 5.

[0029] The working principle of this utility model is as follows: When in use, the power is turned on and the circular glass to be processed is placed on the suction cup device 16. At this time, the second motor 14 installed at the bottom of the platform 1 is powered on and drives the large bevel gear 12 to rotate. The large bevel gear 12 meshes with four sets of small bevel gears 13 that do not interfere with each other and rotates at the same time, thereby driving the four sets of lead screws 4 to rotate. The lead screws 4 drive the L-shaped column 2 to move in the slot opened in the platform 1 through the thread. At this time, the four sets of L-shaped column 2 can move synchronously towards the center.

[0030] Each L-shaped column 2 is equipped with a slider 11, which can move up and down inside the L-shaped column 2. Each slider 2 is equipped with a telescopic wheel frame 10 on one side. When the four sets of L-shaped columns 2 move synchronously towards the center, the positioning wheel 8 is passively moved towards the center under the drive of the L-shaped columns 2. When the U-shaped wheel surface of the positioning wheel 8 contacts the edge of the glass, the four sets of positioning wheels 8 adjust the position of the circular glass and clamp the circular glass at the same time. The spring 9 installed on the telescopic wheel frame 10 plays a role in protecting the glass and balancing the force while the positioning wheel 8 clamps the glass.

[0031] After the glass position is adjusted, the suction cup device 16 is connected to the external air source to clamp the glass. At the same time, the pneumatic telescopic frame 15 is also connected to the external air source. The external air source drives the suction cup device 16 to rise and fall, thereby adjusting the glass height. The four positioning wheels 8 are passively raised after clamping the glass, which drives the slider to rise in the L-shaped column 2.

[0032] The glass rises under the action of the pneumatic telescopic frame 15 and presses against the four rubber wheels 5. The four rubber wheels 5 ensure that the glass is subjected to uniform force, and at the same time, there is a large friction between the rubber wheels 5 and the glass. At this time, the two sets of mirror-mounted drive devices 3 are energized at the same time. The first motor 301 drives the transmission wheel 302 to rotate, thereby driving the lower transmission wheel 302 to rotate through the transmission belt 303. At this time, the transmission wheel 302 can drive the rubber wheel 5 to rotate through the rotating shaft 6, so that the circular glass can rotate at a uniform speed while being pressed by the four rubber wheels 5. At this time, an external edge grinding device can be used to process the circular glass.
