Description

Technical Field

[0001] The present invention belongs to the field of cold processing of daily-use glass blanks, and particularly relates to an automatic laser cutting system. 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 bursting methods include mechanical grinding wheel bursting, flame bursting, etc.

[0003] Mechanical grinding wheel bursting: When the grinding wheel rotates at high speed and contacts the glass surface, mechanical force will be applied to 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 generate 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, and finally cause the glass to break at a specific part, thus achieving bursting.

[0004] When bursting 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 bursting 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 bursting surface of the glass during the grinding process.

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

[0007] During the flame bursting 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 the glass products. Especially for some glass products with high appearance requirements, such as glass handicrafts, high-grade glassware, etc., the edge defects will seriously affect the grade and value of the products;

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

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] As Figures 1-4 , this embodiment provides an automatic laser cutting system, including a three-axis moving assembly, a laser assembly, a jaw assembly, an upper and lower loading conveyor belt, and a product support assembly;

[0049] The daily-use glass is placed on the upper and lower loading conveyor belt. The jaw assembly is connected to the three-axis moving assembly. The jaw assembly clamps the daily-use glass on the upper and lower loading conveyor belt. Through the movement of the three-axis moving assembly, the jaw assembly moves to directly above the product support assembly, and clamps the product support assembly to support the mouth of the daily-use glass. The laser assembly is located on one side of the jaw assembly and the laser assembly points to the daily-use glass. The mouth of the daily-use glass is cut by the laser. After cutting, the three-axis moving assembly drives the jaw assembly to move above the upper and lower loading conveyor belt, and places the daily-use glass back on the upper and lower loading conveyor belt.

[0050] The upper and lower loading conveyor belt consists of a conveyor belt driving servo motor 30, a conveyor belt driving reduction motor 31, a conveyor belt mesh belt 32, and a conveyor belt support 33, and triggers the operation of the conveyor belt servo motor at a set speed according to the control system instruction.

[0051] 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 product to prevent shaking or displacement during the laser notch-making process, ensuring the accuracy of the notch-making position. At the same time, with the equipped product support component, the notch-making part of the glass product can be quickly and accurately positioned to the action area of the laser beam.

[0052] 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, so that the laser beam can be precisely focused on the notch-making 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.

[0053] 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.

[0054] In this embodiment, to ensure the stability and heat dissipation of the laser generated by the laser generating device body, the laser generating device body and the guiding lens are sealed in a constant temperature box 29, and the heat generated inside is cooled by the external water-cooled heat dissipation host in a cycle.

[0055] In this embodiment:

[0056] The jaw component includes a first bracket 24 fixedly connected to the three-axis moving component. 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 controlled by the driving cylinder to move up and down. A jaw action finger is installed at the end of the jaw action shaft. The driving cylinder drives the jaw action shaft to rise, pulling the jaw action finger to clamp the daily-use glass.

[0057] The jaw component further includes a second bracket 25 fixedly connected to the three-axis moving component. A fixed outer sleeve 18 is arranged 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 arranged 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.

[0058] It should be noted that the first bracket 24 and the second bracket 25 can be fixed on any structure, as long as it satisfies that the jaw component is controlled to be above the product support component. For example, Figure 3 , in this embodiment, the first bracket 24 and the second bracket 25 are fixed on the three-axis moving component.

[0059] The three-axis moving assembly includes a Y-axis moving part, a Z-axis moving part, and an X-axis moving part.

[0060] As Figure 6 , the Y-axis moving part is composed of a Y-axis driving servo motor 34, a Y-axis slide 35, and a Y-axis moving member 36. The first bracket and the second bracket are fixedly connected to the Y-axis moving member. The Y-axis moving member is slidably connected within the Y-axis slide and is driven to move along the Y-axis slide by the Y-axis driving servo motor.

[0061] As Figure 8 , the Z-axis moving part is composed of a Z-axis driving servo motor 37, a Z-axis moving lead screw 38, a Z-axis support frame 39, and a Z-axis moving member 40. The Y-axis slide is connected to the Z-axis moving member. The Z-axis moving lead screw is disposed within the Z-axis support frame. The output end of the Z-axis driving servo motor is connected to the Z-axis moving lead screw. A lead screw connecting nut is provided on the Z-axis moving member and is in screw connection with the Z-axis moving lead screw;

[0062] As Figure 7 , the X-axis moving part is composed of an X-axis driving servo motor 41, an X-axis bracket 42, an X-axis slide 43, and an X-axis moving member 44. The X-axis bracket supports the X-axis slide. The X-axis moving member is slidably connected within the X-axis slide and is driven to move along the X-axis slide by the X-axis driving servo motor. The Z-axis support frame is connected to the X-axis moving member.

[0063] In this embodiment, the specific structure of the jaw action shaft slidably connected vertically within the rotating cylinder 28 is as follows: The jaw action shaft is provided with a chute, and the inner wall of the rotating cylinder 28 is provided with a slider that is stuck within the chute. When the driving cylinder controls the lifting of the jaw action shaft, the jaw action shaft will not rotate but only move up and down.

[0064] When the rotating cylinder 28 rotates, since the slider is stuck within the chute, the jaw action shaft follows the rotation. The jaw action shaft is rotatably connected to the piston rod of the driving cylinder. The rotation of the jaw action shaft does not affect the driving cylinder.

[0065] In this embodiment, when the driving cylinder drives the jaw action shaft to rise, it pulls the jaw action fingers to clamp the daily-use glass. The specific implementation method is as Figure 5 :

[0066] 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 plurality of notches 164 pointing towards the center of the disk body. A toothed disk 163 is hinged on the disk body, and 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.

[0067] The claw serves as a finger and is slidably connected within the notch, and the top of the claw is a tooth surface meshing with the toothed disk.

[0068] The driving cylinder works, the clamping jaw action shaft rises, and the gear plate hinged to the clamping jaw action shaft rotates, driving the clamping jaws to gather inward, forming fingers that contract to clamp daily glass.

[0069] Working process: First, the cylinder 15 is driven to drive the gripper action shaft 14 to rise. The gripper action finger 16 is installed at the end of the gripper action shaft 14. After the finger contracts and clamps the product, the driven synchronous wheel 17 starts to rotate under the drive of the frequency conversion motor 26. The synchronous wheel 17 is installed on the outside of the action shaft. When the action shaft rotates, it also drives the gripper action finger 16 to rotate.

[0070] The product support assembly includes a bottom support frame 20, and a mouth positioning support frame is provided on the bottom support frame 20.

[0071] The mouth positioning support frame is provided with an upwardly protruding mouth positioning hemisphere 22 .

[0072] 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 .

[0073] The bottom support frame 20 is connected to the mouth positioning support frame via a height adjuster 23 .

[0074] 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, the worm gear assembly is used for control.

[0075] The height adjuster 23 controls the overall rise of the product and sends the product to the clamping assembly. After the clamping assembly clamps the product, the mouth positioning cylinder 27 lifts the mouth positioning hemisphere to position the mouth of the product.

[0076] The main function of positioning: when the gripper fingers hold the product and rotate, 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 fingers rotate, 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 blasting.

[0077] Further, such as Figure 9 In this embodiment, a burner part is added to the system, and the burner part includes a flame burner nozzle 45 and a flame burner bracket 46;

[0078] When the laser-cut glass product is moved to the burning station by the X-axis moving part, the control system sends a signal, the natural gas control valve opens, and the flame burner nozzle 45 sprays flames to burn the corners of the laser-cut glass cross section into rounded corners to prevent the right-angled corners from hurting people's hands.

[0079] Working principle process of this system:

[0080] After the clamping jaw assembly completes the action of grasping the glass product to be processed on the loading and unloading conveyor belt, at this time, the Y-axis will lift the entire clamping jaw assembly upward to a set distance. The main purpose is to prevent the glass product to be processed from colliding with the conveyor belt during the movement.

[0081] When the Y-axis slide lowers the product to be processed grasped by the clamping jaw to a set horizontal height, the mouth positioning contact uses the mouth positioning hemisphere to contact the mouth of the glass product to be processed under the drive of the mouth positioning cylinder. After a time delay, at this time, it starts to rotate driven by the variable-frequency motor, and simultaneously drives the clamping jaw to rotate through the synchronous belt, waiting for the laser machine to emit laser for cutting;

[0082] Explanation of the actions of other devices:

[0083] Height adjuster: The function of this device is to adjust the height of the positioning device. Since the models of the glass products to be processed are different, resulting in different heights, and the stroke of the driving cylinder is fixed, this device is used to pre-adjust the required height in advance;

[0084] The first bracket and the second bracket are fixedly connected to the Y-axis moving member. After the clamping jaw assembly clamps the product, it needs to move vertically up and down through the Y-axis slide. The purpose is to prevent the product to be processed clamped by the clamping jaw from colliding with the conveyor belt and other devices when moving in the Z-axis direction;

[0085] After the clamping jaw assembly clamps the product to be processed, the Y-axis rises to a set distance, and the Z-axis moves the Y-axis and the clamping jaw assembly in the X-axis direction until directly above the product support assembly. After the laser cutting is completed, the X-axis moves the clamping jaw assembly to the burning mouth part. After the flame spraying is completed, it returns to directly above the loading and unloading conveyor belt;

[0086] And so on.
