Description

Technical Field

[0001] The present invention belongs to the field of cold processing of daily-use glass blanks, and particularly relates to a device for laser cutting daily-use glass. Background Art

[0002] In the field of cold processing of daily-use glass blanks, with the wide application of glass products in daily life and industrial production, higher requirements are put forward for the processing accuracy, quality, and production efficiency of glassware. Traditional glass cracking methods include mechanical grinding wheel cracking, flame cracking, etc.

[0003] Mechanical grinding wheel cracking: When the grinding wheel rotates at high speed and contacts the glass surface, mechanical force will be exerted on the glass. The abrasive grains on the surface of the grinding wheel are like countless tiny cutting edges. When the grinding wheel contacts the glass, the abrasive grains will cut into the glass surface. Due to the high rotational speed of the grinding wheel, this cutting action will cause local stress concentration on the glass surface. Glass is a brittle material. When the local stress exceeds the strength limit of the glass, cracks will begin to appear on the glass. With the continuous action of the grinding wheel, these cracks will continue to expand and connect with each other, eventually causing the glass to break at a specific location, thus achieving cracking.

[0004] When cracking with a grinding wheel, a large number of high-speed flying fragments will be generated. These fragments are like bullets and have a strong impact force. They may hit the operator's body, face, eyes and other parts, causing serious cuts, stabs or even more serious injuries such as blindness;

[0005] In addition, after cracking with a grinding wheel, its original shape and size change, and it can no longer maintain a uniform grinding surface. This will result in uneven grinding amounts on the cracking surface of the glass during the grinding process.

[0006] Flame cracking of glass products is to locally heat the glass with a flame to break it to achieve the processing purpose.

[0007] During the flame cracking process, the edges of the glass are affected by high temperature and are prone to problems such as unevenness, burrs, and notches. These defects will greatly reduce the appearance quality of glass products. Especially for some glass products with high appearance requirements, such as glass handicrafts and high-grade glassware, edge defects will seriously affect the grade and value of the products;

[0008] In addition: Flame cracking uses an open flame for heating, which poses a certain fire hazard. If the operation is improper, the flame may cause the surrounding flammable materials to burn, resulting in safety accidents. In addition, the glass may break and fly during the cracking process, causing harm to the operator's eyes and body. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will further elaborate on the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0035] As Figure 1-2 , this embodiment provides a device for laser cutting daily-use glass, including a laser component, a jaw component, and a product support component;

[0036] The product support component is used to support the daily-use glass 19. The jaw component is located directly above the product support component and clamps the daily-use glass 19 on the product support component. The laser component is located on one side of the jaw component, and the laser component points to the daily-use glass 19, and the daily-use glass 19 is cut by the laser.

[0037] It should be noted that in this embodiment, the product support component is arranged on the ground or other structures. The jaw component can firmly fix the daily-use glass 19 product, prevent shaking or displacement during the laser notching process, and ensure the accuracy of the notching position. At the same time, with the equipped product support component, the to-be-notched part of the glass product can be quickly and accurately positioned to the action area of the laser beam.

[0038] The laser component includes a base platform 10. A laser generator body 11 is arranged on the base platform 10. The laser generator body 11 is provided with a laser guiding lens 12 and a laser focal length adjusting device 13 to adjust the laser, and can accurately focus the laser beam on the to-be-notched position on the glass surface, ensuring that the laser with high energy density acts on a very small area, and improving the cutting accuracy and effect.

[0039] A platform displacement mechanism is arranged below the base platform 10. In this embodiment, the function of the platform displacement mechanism is to adjust the position of the base platform 10. The platform displacement mechanism can adopt screw drive or cylinder expansion and contraction. In this embodiment, screw drive is adopted.

[0040] In this embodiment:

[0041] The jaw component includes a first bracket 24. A driving cylinder is fixed on the first bracket 24. The piston rod of the driving cylinder is rotatably connected to a jaw action shaft. The jaw action shaft is lifted and lowered by the control of the driving cylinder. The end of the jaw action shaft is provided with jaw action fingers. The driving cylinder drives the jaw action shaft to rise and pulls the jaw action fingers to clamp the daily-use glass;

[0042] The jaw assembly further includes a second bracket 25. A fixed outer sleeve 18 is provided on the second bracket 25. A rotating cylinder 28 is rotatably sleeved inside the fixed outer sleeve. The jaw action shaft is vertically slidably connected inside the rotating cylinder 28. A synchronous pulley is installed on the rotating cylinder 28. A variable-frequency motor 26 is provided on the second bracket 25. The output shaft of the variable-frequency motor 26 is connected to the synchronous pulley through a synchronous belt. The synchronous pulley rotates under the drive of the variable-frequency motor 26, driving the jaw action shaft to rotate.

[0043] It should be noted that the first bracket 24 and the second bracket 25 can be fixed to any structure, as long as it satisfies that the control jaw assembly is located above the product support assembly. For example, Figure 3 in this embodiment, the first bracket 24 and the second bracket 25 are fixed to the three-dimensional adjustment frame 29.

[0044] The specific structure of the jaw action shaft vertically slidably connected inside the rotating cylinder 28 in this embodiment is as follows: a chute is provided on the jaw action shaft, and a slider is provided on the inner wall of the rotating cylinder 28. The chute is stuck in the chute.

[0045] In this embodiment, the driving cylinder drives the jaw action shaft to rise, pulling the jaw action fingers to clamp the daily-use glass. The specific implementation method is, for example, Figure 4 :

[0046] The jaw action fingers are a combined structure of a disk body 161 and a claw 162. The disk body is fixedly connected to the lower end of the rotating cylinder. The disk body is provided with a number of notches 164 pointing to the middle. A toothed disk 163 is hinged on the disk body. The tooth surface of the toothed disk points into the notch. The lower end of the jaw action shaft is hinged to the edge of the toothed disk.

[0047] The claw serves as a finger and is slidably connected in the notch, and the top of the claw is a tooth surface meshing with the toothed disk.

[0048] When the driving cylinder works, the jaw action shaft rises, and the toothed disk hinged to the jaw action shaft rotates, driving the claws to gather inward, forming the fingers to contract and clamp the daily-use glass.

[0049] Working process: First, the driving cylinder 15 drives the jaw action shaft 14 to rise. The jaw action fingers 16 are installed at the end of the jaw action shaft 14. After the fingers contract to clamp the product, the driven synchronous pulley 17 starts to rotate under the drive of the variable-frequency motor 26. The synchronous pulley 17 is installed outside the action shaft, driving the action shaft to rotate at the same time, and also driving the jaw action fingers 16 to rotate.

[0050] The product support assembly includes a bottom support frame 20, and a mouth positioning support frame is provided on the bottom support frame 20.

[0051] The mouth positioning support frame is provided with an upwardly convex mouth positioning hemisphere 22.

[0052] The mouth positioning support frame includes a base plate 21 and a mouth positioning cylinder 27 located on the base plate 21 , and the mouth positioning hemisphere is arranged on the output shaft of the mouth positioning cylinder 27 .

[0053] The bottom support frame 20 is connected to the mouth positioning support frame via a height adjuster 23 .

[0054] It should be noted that the height adjuster 23 can adopt a cylinder assembly, an electric telescopic rod assembly, or a worm gear assembly. In this embodiment, a worm gear assembly is used for control.

[0055] The height adjuster 23 controls the overall rise of the product and delivers the product to the clamping jaw assembly. After the clamping jaw assembly clamps the product, the mouth positioning cylinder 27 lifts the mouth positioning hemisphere to position the mouth of the product.

[0056] The main function of positioning: when the gripper fingers hold the product and rotate it, the product may not be clamped properly when being gripped by the gripper fingers, causing the mouth of the product to be eccentric during rotation. At this time, before the gripper rotates, the bottom mouth positioning support frame extends the mouth positioning hemisphere through the height adjuster to support the mouth of the product. In this way, the product will not be eccentric during rotation, which is more conducive to laser mouth blasting.
