Description

Technical Field

[0001] The utility model relates to the technical field of hollow glass processing, in particular to an air extraction device for hollow glass processing. Background Art

[0002] Insulating glass is made of two (or three) pieces of glass, using a high-strength and high-airtightness composite adhesive to bond the glass sheets to an aluminum alloy frame containing a desiccant to produce high-efficiency sound-proof and heat-insulating glass. During the preparation process of insulating glass, it is necessary to use a vacuum device to evacuate the interior. When using a vacuum device for some insulating glass processing, the staff first places the vacuum glass into the slot on the workbench, and then the staff holds the vacuum tube and inserts it into the vacuum port on the side of the insulating glass. Then the vacuum tube generates suction through an air pump to vacuum the insulating glass. However, the slot structure of the device is fixed, and it is only suitable for vacuuming insulating glass of the same thickness, with a low scope of application. During the vacuuming process, the staff needs to hold the vacuum equipment for a long time, which increases the physical exertion of the staff. At the same time, after the hollow glass is evacuated, the vacuum tube is separated from the vacuum port of the hollow glass. At this time, there is a lack of sealing components at the vacuum port of the hollow glass, allowing external gas to enter the interior of the insulating glass, which needs to be improved.

Place the insulating glass on the upper side of the storage seat, then the single-chip microcomputer synchronously starts the two adjacent electric push rods 1 so that their telescopic ends drive the corresponding sliding frames to move along the slide groove close to the center of the device. At the same time, the single-chip microcomputer starts the distance meter to measure the distance between the horizontal limit seat and the side of the insulating glass and transmit it to the single-chip microcomputer.

After the evacuation is completed, the sealing seat quickly seals the rubber air nozzle through the spring force and the pressure difference between the inside and outside of the insulating glass. At this time, the rubber air nozzle itself is adsorbed to the air suction port on the side of the insulating glass, and then the single-chip microcomputer controls the electrical components to reset, effectively avoiding the gas reflux phenomenon at the air suction port after the hollow glass is evacuated due to untimely sealing. The vacuum device for hollow glass processing is easy to use. After the evacuation is completed, the spring force and the pressure difference are used to automatically seal the air suction port of the insulating glass to avoid external gas from entering the inside of the insulating glass.

Then, the insulating glass is placed on the upper side of the storage seat 4, and the contact surface between the storage seat 4 and the insulating glass is protected from deformation by the rubber pad 5. After the insulating glass is fixed and connected to the exhaust position, the external air pump is started, and suction is generated at the rubber air nozzle 12 through the air pipe. After receiving a certain suction force, the blocking seat 16 moves left, the telescopic end of the telescopic column 14 and the spring 15 contract, and the rubber air nozzle 12 opens, thereby exhausting the insulating glass.

The sliding frame 61 is slidably connected to the inside of the slide slot. The top wall of the sliding frame 61 is provided with an arc limit seat 64 through evenly distributed telescopic columns 1 62 and spring 1 63. The spring 1 63 is movably connected to the outer end of the adjacent telescopic column 1 62. The middle part of the sliding frame 61 is provided with a horizontal limit seat 65. The automatic centering fixing mechanism 6 also includes a distance meter 66. The distance meter 66 is arranged in the middle part of the horizontal limit seat 65. The distance meter 66 is bidirectionally electrically connected to the single-chip computer 2. The automatic centering fixing mechanism 6 also includes an electric push rod 67, which is arranged between the sliding frame 61 and the connecting seat 3. The input end of the electric push rod 67 is electrically connected to the output end of the single-chip computer 2. The single-chip computer 2 synchronously starts two adjacent electric push rods 67 so that their telescopic ends drive the corresponding sliding frame 61 to move along the slide groove close to the center of the device. At the same time, the single-chip computer 2 starts the distance meter 66, and the distance meter 18 emits a light signal to the side of the adjacent insulating glass and reflects it back to the initial position. According to the propagation speed and time of the light signal, the distance between the horizontal limit seat 65 and the side of the insulating glass is determined, and the measured result is transmitted to the single-chip computer 2 in the form of an electrical signal. As the sliding frame 61 moves toward the device The arc-shaped limit seat 64 moves in the middle, and the arc surface of the arc-shaped limit seat 64 contacts the upper edge of the side corresponding to the insulating glass. The arc-shaped limit seat 64 moves up to the upper side of the insulating glass, and the telescopic end of the telescopic column 62 and the spring 63 contract. The arc-shaped limit seat 64 limits the vertical movement of the insulating glass through the compression elastic force of the spring 63. When the single-chip microcomputer 2 obtains that the results measured by the two adjacent rangefinders 18 are both zero, the insulating glass is horizontally limited by the horizontal limit seat 65 at this time, so that the hollow glass is completely limited in the exhaust. The device can automatically limit the exhaust of insulating glass of different thicknesses, and then the rubber air nozzle 12 is inserted into the tapered mouth of the exhaust pipe 11, and then the linear motor 7 is controlled by the single-chip microcomputer 2 to move from The exhaust part of the device is longitudinally regulated, the single chip 2 controls the linear motor 2 8 to perform lateral position regulation on the exhaust part of the device, and the single chip 2 controls the electric push rod 2 10 so that its telescopic end drives the exhaust pipe 11 to move vertically, thereby performing vertical position regulation on the exhaust part of the device. The single chip 2 controls the rubber air nozzle 12 to enter and press against the exhaust port on the side of the hollow glass. The hollow glass and the exhaust part are mechanically connected and fixed, and no manual support is required, which is convenient to use. The exhaust device for hollow glass processing can automatically exhaust and fix vacuum glasses of different thicknesses, and the exhaust part is connected to the exhaust port of the hollow glass through mechanical transmission, thereby reducing the labor intensity.

[0024] Among them: it also includes a single-chip microcomputer 2, which is arranged on the front side of the operating table 1. The input end of the single-chip microcomputer 2 is electrically connected to the external power supply, and the output end of the single-chip microcomputer 2 is electrically connected to the input ends of the linear motor 1 7, the linear motor 2 8 and the electric push rod 2 10 respectively, so that the control of electrical components is convenient.

[0025] The working principle of the vacuum device for hollow glass processing provided by the utility model is as follows: when vacuuming the hollow glass, firstly, the device is fixed to the specified position by bolts through the support seat 17, then the air pipe on the vacuum pipe 11 is connected to the external air pump, then the hollow glass is placed on the upper side of the storage seat 4, and the contact surface between the storage seat 4 and the hollow glass is protected from deformation by the rubber pad 5, then the single-chip microcomputer 2 synchronously starts two adjacent electric push rods 67 so that their telescopic ends drive the corresponding sliding frame 61 to move along the slide groove close to the center of the device, and at the same time, the single-chip microcomputer 2 starts the rangefinder 66, and the rangefinder 18 emits a light signal to illuminate the adjacent hollow glass. The side of the insulating glass is reflected back to the initial position, and the distance between the horizontal limit seat 65 and the side of the insulating glass is determined according to the propagation speed and time of the light signal, and the measured result is transmitted to the single-chip microcomputer 2 in the form of an electrical signal. As the sliding frame 61 moves toward the middle of the device, the arc surface of the arc limit seat 64 contacts the upper edge of the side corresponding to the insulating glass, and the arc limit seat 64 moves up to the upper side of the insulating glass. The telescopic end of the telescopic column 1 62 and the spring 1 63 contract, and the arc limit seat 64 is used to limit the vertical movement of the insulating glass through the compression elastic force of the spring 1 63. When the single-chip microcomputer 2 obtains that the results measured by the two adjacent rangefinders 18 are both zero, the insulating glass is moved vertically through the horizontal limit seat 65. The horizontal limit is performed to completely limit the exhaust of the insulating glass. The device can automatically limit the exhaust of insulating glass of different thicknesses. Then, the rubber air nozzle 12 is inserted into the tapered mouth of the exhaust pipe 11. Then, the linear motor 17 is controlled by the single-chip microcomputer 2 to adjust the longitudinal position of the exhaust part of the device. The linear motor 28 is controlled by the single-chip microcomputer 2 to adjust the lateral position of the exhaust part of the device. The single-chip microcomputer 2 controls the electric push rod 210 so that its telescopic end drives the exhaust pipe 11 to move vertically, thereby adjusting the vertical position of the exhaust part of the device. The rubber air nozzle 12 is controlled by the single-chip microcomputer 2 to enter and press against the exhaust port on the side of the insulating glass. By adjusting the distance between the insulating glass and the exhaust part, the rubber air nozzle 12 can be adjusted. The rubber air nozzle 12 is mechanically connected and fixed, and no manual support is required, which is easy to use. Then the external air pump is started to generate suction at the rubber air nozzle 12 through the air pipe. The sealing seat 16 moves left after receiving a certain suction force, and the telescopic end of the telescopic column 14 and the spring 15 contract, so that the rubber air nozzle 12 is opened, so as to evacuate the hollow glass. After the air is evacuated, the sealing seat 16 quickly blocks the rubber air nozzle 12 through the spring force and the pressure difference between the inside and outside of the hollow glass. At this time, the rubber air nozzle 12 is adsorbed to the air suction port on the side of the hollow glass, and then the single-chip microcomputer 2 controls the electrical components to reset, which effectively avoids the gas reflux phenomenon caused by the failure to close the air suction port in time after the hollow glass is evacuated. It is easy to use.
