Description

Technical Field

[0001] The present invention relates to the field of glass production equipment, in particular to cutting equipment for optical glass. Background Art

[0002] Optical glass cutting is a high-precision, highly complex manufacturing process primarily used to produce optical components such as lenses, prisms, and filters. Its core focus is achieving high-precision kerf cutting, minimal surface damage, a low heat-affected zone, and controlled edge perpendicularity.

[0003] To avoid thermal stress, mechanical cold cutting is usually adopted, that is, diamond sliding cutting and external mechanical force are used to break it. The glass fragments generated during the cutting process are easy to splash and pollute the processing environment. At the same time, the friction during diamond cutting can easily cause burns to the surface of the glass, especially when the flying debris splashes in front of the cutting knife's path. Due to the friction between the tool, debris and glass, it is particularly easy to cause defects such as burrs and tiny cracks at the cutting position, affecting the high light transmittance performance.

DETAILED DESCRIPTION

[0018] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] See also Figures 1 to 9The present invention provides a technical solution: an optical glass cutting device, comprising a glass support 1, a glass placing plate 2 being provided at the upper end of the glass support 1, a glass fixing structure 3 being provided below the glass placing plate 2 and inside the glass support 1, a plurality of fixed suction cups 4 and a vibration rod 5 being provided in the glass fixing structure 3, the fixed suction cup 4 being used to adsorb a glass plate 6 placed on the glass placing plate 2, a moving structure 7 being provided on the glass support 1, a glass cutting device 8 being provided on the moving structure 7, the moving structure 7 driving the glass cutting device 8 to move on the glass and cut at the same time, and the glass cutting device 8 with the recovery structure 84 can achieve better cutting of the glass and prevent the debris generated by the cutting from splashing.

[0020] In this embodiment, the glass placement plate 2 includes a fixed frame 21 and a plurality of heating rods 22. The heating rods 22 are evenly arranged in the fixed frame 21 and heating wires are arranged on the heating rods 22. The setting of the heating wires helps to heat the glass to 40 degrees Celsius, heating the cutting liquid sprayed by the atomizing nozzle 832. By heating, the viscosity of the cutting liquid is reduced and its fluidity is increased, which facilitates the cutting liquid to penetrate into the cutting seam produced by cutting, which is conducive to the subsequent disconnection of the glass from the cutting seam.

[0021] In this embodiment, the glass fixing structure 3 includes an outer frame 31 and a cross beam 32. The fixed suction cup 4 and the vibration rod 5 are evenly arranged and fixed on the cross beam 32. The fixed suction cup 4 fixes the glass by suction, and the vibration rod 5 is only close to the glass but not in contact with it. The vibration generated accelerates the penetration of the cutting liquid into the cutting seam.

[0022] In this embodiment, the movable structure 7 includes a longitudinal track 71 and a transverse track 72. The longitudinal track 71 is fixedly installed on both sides of the top of the glass bracket 1. The two ends of the transverse track 72 are fixed on the longitudinal track 71 and can be driven to move by the longitudinal track 71. The transverse track 72 is provided with a fixed seat 73, and the fixed seat 73 is provided with a steering gear 74. The longitudinal track 71 and the transverse track 72 are used to drive the fixed seat 73 to move on the glass, and the steering gear 74 is used to drive the glass cutting device 8 to rotate, so that the atomizing nozzle 832 is always in front of the cutting knife 82, thereby achieving the purpose of spraying first and then cutting.

[0023] In this embodiment, the glass cutting device 8 includes a cover tube 81, a cutting knife 82, a spray pipe 83 and a recovery structure 84. The top of the cover tube 81 is fixedly connected to the base of the cutting knife 82, and the top of the cutting knife 82 is fixedly connected to the output shaft of the servo 74. The spray pipe 83 and the recovery structure 84 are respectively fixedly installed on both sides of the cutting knife 82. The recovery structure 84 is used to help the cutting liquid to be applied and recovered. The cutting knife 82 cuts the glass, the spray pipe 83 sprays the cutting liquid, and the recovery structure 84 recovers the debris and cutting liquid generated by the cutting.

[0024] In this embodiment, the injection pipe 83 includes an insulation pipe 831 and an atomizing nozzle 832. The insulation pipe 831 is connected to an external cutting liquid delivery device. The atomizing nozzle 832 is installed at the bottom of the insulation pipe 831 and sprays cutting liquid. The insulation pipe 831 ensures the temperature of the cutting liquid entering the atomizing nozzle 832. The atomizing nozzle 832 sprays the cutting liquid. The cutting liquid here is preferably kerosene. The insulation pipe 831 ensures that the temperature of the sprayed atomized kerosene is between 5-10°C.

[0025] In this embodiment, the recovery structure 84 includes a high-speed dial wheel 841, a recovery bottom cover 843 and an upper collection cover 842. The recovery bottom cover 843 is fixedly installed at the bottom of the upper collection cover 842 and forms an opening on one side of the upper collection cover 842. The high-speed dial wheel 841 is fixedly installed at the opening. The side of the high-speed dial wheel 841 is provided with an arc-shaped plate 844 fixedly installed on the upper collection cover 842. The high-speed dial wheel 841, the recovery bottom cover 843 and the upper collection cover 842 are all installed in the protective cover 85, and the protective cover 85 is fixedly installed in the cover tube 81. After the atomizing nozzle 832 sprays the cutting fluid, the cutting knife 82 cuts the glass with the cutting fluid, and the generated debris will be blocked by the cutting fluid with higher viscosity and retained in the cutting fluid. Then, through the rotation of the high-speed dial wheel 841, the cutting fluid and debris are rotated to the collection knife and recovered in the bottom cover 843.

[0026] In this embodiment, a motor is connected to the side of the high-speed dial 841, and a dial plate made of elastic material is provided on the high-speed dial 841. The dial plate contacts the recovery bottom cover 843 when rotating. When the high-speed dial 841 rotates, the debris mixed with the cutting fluid on the glass surface is collected and thrown onto the upper collection cover 842 and the recovery bottom cover 843 through rotation. The contact between the dial plate and the recovery bottom cover 843 can prevent a gap from being generated between the two, causing the debris to fly out. In this embodiment, a suction tube is provided on the top of the upper collecting cover 842, and the suction tube is connected to an external suction device. The continuous suction of the external device generates suction, which can not only prevent debris from flying out, but also can timely suck away the collected cutting fluid and debris.

[0027] In this embodiment, a suction layer is provided in the recovery bottom cover 843, the top of the suction layer is connected to the upper collecting cover 842, and the lowest opening of the suction layer is located at the lowest point of the recovery bottom cover 842. Suction is generated at the lowest point of the suction layer, which can make the cutting fluid entering the upper collecting cover 842 and the recovery bottom cover 843 gather at the lowest point of the recovery bottom cover 842, so as to facilitate suction recovery.

[0028] Working principle: When in use, first place the glass plate 6 on the glass placing plate 2, and fix it from the bottom through multiple fixed suction cups 4 on the glass fixing structure 3, and then start the moving structure 7 to start cutting the glass. During cutting, the cutting liquid is sprayed out by the injection pipe 83, and the debris and cutting liquid generated by the cutting are recovered by the recovery structure 84. The heating wire helps to heat the glass and heat the cutting liquid sprayed by the atomizing nozzle 832. At the same time, heating and vibration accelerate the cutting liquid to penetrate into the cutting seam. The debris generated by cutting will be blocked by the cutting liquid with higher viscosity and retained in the cutting liquid. Then, through the rotation of the high-speed dial 841, the cutting liquid and debris are rotated to the collection knife recovery bottom cover 843, and the collected cutting liquid and debris are sucked away through continuous suction of external equipment.

[0029] It is known from common technical knowledge that the present invention can be modified by other methods without departing from its spirit or essential features, and is not exclusive. All modifications within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
