Description

Technical Field

[0001] This utility model relates to the field of glass cutting machines, and more particularly to a glass laser cutting machine. Background Technology

[0002] Laser glass cutting technology, as a core method of non-contact processing, is widely used in fields such as electronic displays, architectural glass, and automotive glass due to its advantages such as high precision, low heat-affected zone, and no mechanical stress.

[0003] Traditional mechanical cutting is prone to problems such as glass chipping and microcracks, while laser cutting uses a focused high-energy beam to melt or vaporize the material, and with the help of auxiliary gas purging to form a kerf, it significantly improves the cutting quality. However, with the increasing demand for ultra-thin glass (thickness <0.5mm) and irregularly shaped glass, existing cutting equipment still has many shortcomings.

[0004] For example, there are challenges in positioning and clamping: existing equipment mostly uses an "L"-shaped lateral positioning seat, but while its silicone material can buffer pressure, it cannot dynamically adjust the support force to adapt to stress changes during the cutting process, causing the glass cutting end to warp or break due to uneven stress; cutting efficiency bottlenecks: traditional equipment relies on a single cutting table, and the glass loading / unloading and cutting processes cannot be carried out in parallel, resulting in an idle rate of over 30%. For instance, in the glass laser cutting machine disclosed in invention patent CN117001177A, although a translation module is introduced to realize material loading / unloading, the problem of dual-station coordination is not solved. Furthermore, existing glass laser cutting machines lack flexibility during cutting, making it difficult to meet the cutting requirements of irregularly shaped glass. Summary of the Invention

[0005] In view of this, the present invention provides a glass laser cutting machine to solve the above problems.

[0006] A glass laser cutting machine includes a frame, two sliding stage assemblies arranged side-by-side on the frame, and a laser cutting mechanism disposed above the sliding stage assemblies. Each sliding stage assembly includes a first slide rail assembly disposed on a support base, and a low-pressure adsorption stage assembly slidably disposed on the two first slide rail assemblies. Each laser cutting mechanism includes a bracket fixedly mounted on the support base, a laser generator fixedly mounted on the bracket, a second slide rail assembly fixedly mounted on one side of the bracket, a third slide rail assembly fixedly mounted on the side of the bracket opposite to the second slide rail assembly, a laser cutting component fixedly mounted on the second slide rail assembly, and a laser dicing component fixedly mounted on the third slide rail assembly. The extending directions of the second and third slide rail assemblies are perpendicular to the extending directions of the first slide rail assemblies. Each laser cutting component includes a substrate fixedly mounted on the second slide rail assembly, a vertical moving component fixedly mounted on the substrate, and a cutting component fixedly mounted on the vertical moving component. The laser splitting assembly includes a vertically moving splitting component fixedly mounted on the slide plate of the third slide rail assembly, and a splitting laser head fixedly mounted on the vertically moving splitting component.

[0007] Furthermore, the first slide rail assembly includes a mounting bracket fixedly mounted on the frame, two linear guide rails spaced apart within the mounting bracket, a plurality of electric sliders movably mounted on the linear guide rails, a sliding plate fixedly mounted on the electric sliders, two limiting members fixedly mounted on the mounting bracket, and a drag chain fixedly mounted on one side of the mounting bracket.

[0008] Furthermore, the low-pressure adsorption stage assembly includes a stage fixedly mounted on the first slide rail assembly, a low-pressure adsorption tube disposed on one side of the stage, and multiple limiting strips disposed on the edge of the stage.

[0009] Furthermore, multiple air inlets are provided on the platform.

[0010] Furthermore, the bracket is U-shaped, with one side of its open end facing one side of the first sliding component, and is fixedly installed on the support base.

[0011] Furthermore, the frame includes a support base and a cover fixedly mounted on the support base.

[0012] Furthermore, two doors with left and right switches are provided around the machine cover.

[0013] Furthermore, the laser generating device is composed of a gain medium, a pump source, a resonant cavity, a cooling system, and other related auxiliary components.

[0014] Compared with existing technologies, the glass laser cutting machine provided by this utility model includes a frame, two sliding stage assemblies arranged side by side on the frame, and a laser cutting mechanism disposed above the sliding stage assemblies. The two sliding stage assemblies can be coordinated and controlled by a control system, allowing the worker to perform loading and unloading operations on the other sliding stage while one assembly transports glass for cutting, thereby improving the working efficiency of the laser cutting mechanism. Simultaneously, the low-pressure adsorption stage assembly can move back and forth on the first slide rail assembly, and the laser cutting assembly and the laser cleaving assembly can move left and right under the drive of the second and third slide rail assemblies, respectively. Furthermore, the laser cutting assembly and the laser cleaving assembly are respectively equipped with a cutting vertical movement assembly and a cleaving vertical movement assembly, further enabling the laser cutting assembly and the laser cleaving assembly to move vertically up and down, thus allowing the glass laser cutting machine to achieve three-dimensional cutting and improving its flexibility. In addition, the low-pressure adsorption stage assembly fixes the glass by negative pressure adsorption, which improves the fixation stability and avoids the problems of difficulty in adjusting the glass and uneven force after fixation.

[0021] The specific embodiments of this utility model will be described in further detail below. It should be understood that the description of this utility model herein is not intended to limit the scope of protection of this utility model.

[0022] like Figures 1 to 6 The diagram shown is a structural schematic of a glass laser cutting machine provided by this utility model. The glass laser cutting machine includes a frame 10, two sliding stage assemblies 20 arranged side-by-side on the frame 10, and a laser cutting mechanism 30 disposed above the sliding stage assemblies 20. It is conceivable that the glass laser cutting machine should also include other functional components, such as assembly components, electrical connection components, and control systems, all of which are prior art known to those skilled in the art.

[0023] The frame 10 includes a support base 11 and a cover 12 fixedly mounted on the support base 11.

[0024] The support base 11 supports the sliding stage assembly 20 and the laser cutting mechanism 30, allowing them to be assembled into a single unit. The dimensions and structure of the support base 11 are matched to those of the sliding stage assembly 20 and the laser cutting mechanism 30.

[0025] The cover 12 is fixedly mounted on the support base 11 and covers the outside of the laser cutting mechanism 30, thus protecting the laser cutting mechanism 30. This prevents debris from falling and damaging the laser mechanism during use, and also ensures the safety of workers during the cutting process. Two doors 13 with left and right switches are provided around the cover 12. When the laser cutting mechanism 30 malfunctions, these doors 13 can be opened to facilitate maintenance or repair.

[0026] Each of the sliding stage assemblies 20 includes a first slide rail assembly 21 disposed on the support base 11, and a low-pressure adsorption stage assembly 22 slidably disposed on the two first slide rail assemblies 21.

[0027] The first slide rail assembly 21 includes a mounting bracket 211 fixedly mounted on the support base 11, two linear guide rails 212 spaced apart within the mounting bracket 211, a plurality of electric sliders 213 movably mounted on the linear guide rails 212, a slide plate 214 fixedly mounted on the electric sliders 213, two limiting members 215 fixedly mounted on the mounting bracket 211, and a drag chain 216 fixedly mounted on one side of the mounting bracket 211.

[0028] The mounting bracket 211 is used to set the limiting member 213 and the drag chain 216, and to protect the linear guide rail 212, the electric slider 213 and the limiting member 215, thereby preventing debris from falling between the linear guide rails 212 and ensuring the operational stability of the electric slider 213 on the linear guide rails 212.

[0029] The two linear guide rails 212 are spaced apart within the mounting bracket 211.

[0030] Multiple electric sliders 213 are movably mounted on two linear guide rails 212. The electric slider 213 itself is existing technology, integrating a motor and transmission mechanism, and can achieve precise reciprocating linear motion via electrical drive. It is widely used in automation equipment, precision machining, and industrial robots. When powered, the electric slider 213 can reciprocate along the linear guide rail 211 under the action of the servo motor. It is conceivable that the electric slider 213 is also electrically connected to the control system of the cutting machine, allowing its speed and direction of movement to be controlled via software. This control system and control software are existing technology and will not be elaborated further here. The number of electric sliders 213 can be set according to the size and weight of the glass being processed, ensuring precise driving of the low-pressure adsorption platform assembly 22.

[0031] The slide plate 214 is fixedly connected to the electric slider 213, thereby forming a sliding connection between the electric slider 213 and the linear guide rail 212.

[0032] Two limiting members 215 are fixedly mounted on the mounting bracket 211 and located at both ends of the linear guide rail 212. The limiting members 215 are used to restrict the position of the electric slider 213 along the extension direction of the linear guide rail 212 to prevent the electric slider 213 from derailing. The end of the limiting member 215 facing the electric slider 213 can be made of an elastic material, such as silicone or rubber, so as to form a buffer when in contact with the electric slider 213, avoiding excessive inertia during impact that could fling the glass off the low-pressure adsorption platform assembly 22.

[0033] The drag chain 216 is fixedly mounted on the mounting bracket 211 along the extension direction of the linear guide rail 212. It is used to store the relevant electrical connection wires and other connection wires of the sliding platform assembly 20, and to prevent the electrical connection wires from getting tangled or messy during the sliding of the electric slider 213.

[0034] The low-pressure adsorption platform assembly 22 includes a platform 221 fixedly mounted on the first slide rail assembly 21, a low-pressure adsorption tube 222 disposed on one side of the platform 221, and multiple limiting strips 223 disposed on the edge of the platform 221.

[0035] The platform 221 is fixedly connected to the electric slider 213 and moves back and forth along the linear slide rail 212 with the electric slider 213 to transport the glass to the underside of the laser cutting mechanism 30 for cutting. Preferably, the platform 221 can be fixedly mounted on the electric slider 213 using a pad, so that the platform 221 and the electric slider 213 are spaced apart to facilitate the installation of the low-pressure adsorption tube 222. Multiple air inlets 224 are provided on the platform 211.

[0036] Multiple air inlets 224 are distributed throughout the stage 221 and are arranged at equal intervals on the stage 221. The air inlets 224 penetrate the stage 221 so that the low-pressure adsorption tube 222 can adsorb the glass placed on the stage 221 through the air inlets 224.

[0037] One end of the low-pressure adsorption tube 222 can be connected to the stage 221 via a sheet metal vacuum tube, thereby increasing the adsorption area. The sheet metal vacuum tube is a square pipe formed by sheet metal welding, with one side fixedly connected to the stage 221 and communicating with the air inlet 224, and the other side communicating with the vacuum tube 222. The other side of the low-pressure adsorption tube 222 is connected to a vacuum pump, thereby generating negative pressure to adsorb the glass placed on the stage 221.

[0038] The limiting strip 223 is fixedly disposed on the edge of the platform 221 to limit the glass. At the same time, it can also provide positioning when placing the glass, making it easy to quickly place the glass on the platform 221.

[0039] The two sliding stage assemblies 20 can be coordinated and controlled by the control system during operation, so that when one sliding stage assembly 20 is transporting glass for processing, the worker can load and unload the other sliding stage assembly 20, thereby improving the working efficiency of the laser cutting mechanism 30.

[0040] The laser cutting mechanism 30 includes a bracket 31 fixedly mounted on the support base 10, a laser generator 32 fixedly mounted on the bracket 31, a second slide rail assembly 33 fixedly mounted on one side of the bracket 31, a third slide rail assembly 34 fixedly mounted on the side of the bracket 31 opposite to the second slide rail assembly 33, a laser cutting assembly 35 fixedly mounted on the second slide rail assembly 33, and a laser dicing assembly 36 fixedly mounted on the third slide rail assembly 34.

[0041] The bracket 31 is disposed above the sliding platform assembly 20 perpendicular to the extending direction of the linear slide rail 212. It is used to support the laser generating device 32, the second slide rail assembly 33, the third slide rail assembly 34, the laser cutting assembly 35, and the laser dicing assembly 36, thereby facilitating the assembly of the laser generating device 32, the second slide rail assembly 33, the third slide rail assembly 34, the laser cutting assembly 35, and the laser dicing assembly 36 into a whole. The bracket 31 can be U-shaped, with one side of its open end facing one side of the linear slide rail 212, and is fixedly mounted on the support base 11.

[0042] The laser generating device 32 is fixedly mounted on the bracket 31. The laser generating device 32 comprises multiple components, including a gain medium, a pump source, a resonant cavity, a cooling system, and other related auxiliary components. It is used to generate laser light of a corresponding wavelength for application to the laser cutting assembly 35 and the laser dicing assembly 36. The laser generating device 32 itself is prior art and will not be described in detail here.

[0043] The second slide rail assembly 33 and the third slide rail assembly 34 are both arranged perpendicular to the extending direction of the first slide rail assembly 21. The second slide rail assembly 33 and the third slide rail assembly 34 are respectively used to drive the laser cutting assembly 35 and the laser dicing assembly 36 to slide left and right along their extending direction, i.e., perpendicular to the extending direction of the first surgical slide rail assembly 21. The structures of the second slide rail assembly 33 and the third slide rail assembly 34 are the same as those of the first slide rail assembly 21, consisting of a mounting bracket, a linear slide rail, an electric slider slidably mounted on the linear slide rail, and a sliding plate fixedly connected to the electric slider; therefore, further details are omitted here. A cable chain for storing connecting wires is also provided on one side of the second slide rail assembly 33 and the third slide rail assembly 34.

[0044] The laser cutting assembly 35 includes a base plate 351 fixedly mounted on the second slide rail assembly 33, a cutting vertical moving assembly 352 fixedly mounted on the base plate 351, and a cutting assembly 353 fixedly mounted on the cutting vertical moving assembly 352.

[0045] The substrate 351 is used to support the linear motion component 352 and the cutting component 353, thereby facilitating the assembly of the linear motion component 352 and the cutting component 353 into a whole. The substrate 351 is fixedly connected to the slide plate of the second slide rail component 33, so that the laser cutting component 35 can move left and right with the second slide rail component 33.

[0046] The vertical cutting movement assembly 352 includes two vertical guide rails 3521 fixedly mounted on the base plate 351, a lead screw 3522 disposed between the two vertical guide rails 3521, a drive motor 3523 fixedly mounted at one end of the lead screw 3522, and a vertical sliding plate 3524 slidably mounted on the vertical guide rails 3521. The vertical guide rails 3521 are spaced apart vertically on the base plate 351. One end of the lead screw 3522 is fixedly connected to the drive motor 3523 and rotates under the drive of the drive motor 3523. The vertical sliding plate 3524 can be directly slidably connected to the vertical guide rails 3521 or slidably connected to the vertical guide rails 3521 via a slider and connected to the lead screw 3522. When the drive motor 3523 drives the lead screw 3522 to rotate, the vertical slide plate 3524 reciprocates along the vertical guide rail 3521 under the drive of the lead screw 3522, thereby adjusting the axial position of the cutting assembly 353.

[0047] The cutting assembly 353 is used to cut the glass on the sliding stage assembly 20. It includes a cutting laser head 3531 fixedly mounted on the vertical slide plate 3524, and a camera 3532 fixedly mounted on the cutting laser head 3531. The cutting laser head 3531 is connected to the laser generator 32 via an optical fiber, allowing the laser generated by the laser generator 32 to be transmitted to the cutting laser head 3531 via total internal reflection, and used to cut the glass on the sliding stage assembly 20. The laser of the cutting laser head 3531 can be controlled by a control system; for example, when cutting thicker glass, infrared light with a wavelength of 10600nm can be used. The camera 3532 is connected to the control system and is used for positioning and identifying the glass cutting process.

[0048] The laser cleaving assembly 36 is used to perform cleavage processing on the sliding stage assembly 20. It includes a vertically moving cleaving assembly 361 fixedly mounted on the slide plate of the third slide rail assembly 34, and a cleaving laser head 362 fixedly mounted on the vertically moving cleaving assembly 361. The vertically moving cleaving assembly 361 consists of a guide rail slider and a drive motor, which drives the cleaving laser head 362 to move vertically up and down. The cleaving laser head 362 is optically connected to the laser generator 32, thereby outputting a laser of a specific wavelength to cleave the glass. The output wavelengths of the cutting laser head 3531 and the cleaving laser head 362 can be controlled by a control system. The specific wavelength is selected according to the processing technology; for example, when inducing crack formation in the glass, an infrared wave with a wavelength of 1064nm can be used. The structure and working principle of the cleaving laser head 362 are existing technologies and will not be described in detail here.

[0049] Compared with the prior art, the glass laser cutting machine provided by this utility model includes a frame 10, two sliding stage assemblies 20 arranged side by side on the frame 10, and a laser cutting mechanism 30 disposed above the sliding stage assemblies 20. The two sliding stage assemblies 20 can be coordinated and controlled by a control system, so that when one sliding stage assembly 20 is transporting glass for cutting, the worker can perform loading and unloading operations on the other sliding stage assembly 20, thereby improving the working efficiency of the laser cutting mechanism 30. Meanwhile, the low-pressure adsorption stage assembly 22 can move back and forth on the first slide rail assembly 21, and the laser cutting assembly 35 and the laser cleaving assembly 36 can move left and right under the drive of the second slide rail assembly 33 and the third slide rail assembly 34, respectively. The laser cutting assembly 35 and the laser cleaving assembly 36 are respectively equipped with a cutting vertical moving assembly 352 and a cleaving vertical moving assembly 361, further enabling the laser cutting assembly 35 and the laser cleaving assembly 36 to move vertically up and down, thereby allowing the glass laser cutting machine to achieve three-dimensional cutting and improving its flexibility. Furthermore, the low-pressure adsorption stage assembly 22 fixes the glass using negative pressure adsorption, improving the stability of the fixation while avoiding the problems of difficulty in adjusting the glass after fixation and uneven force distribution.
