Description

Technical Field

[0001] The invention relates to the technical field of glass processing, in particular to a cutting device for laser cutting glass. Background Art

[0002] Laser cutting is an advanced processing technology that uses a high-energy laser beam to precisely cut materials. The principle is to quickly melt or vaporize the material by focusing the high temperature generated by the laser beam, and to blow away the slag with the help of auxiliary gases (such as nitrogen, oxygen, etc.) to achieve cutting. The main advantages of laser cutting are high precision, high speed and high flexibility. It can cut a variety of materials, including metals (such as steel, aluminum, copper), non-metals (such as plastics, wood, glass) and composite materials, and the cutting edges are smooth without the need for secondary processing. In addition, laser cutting supports the cutting of complex graphics and is suitable for small batch and multi-variety production needs.

[0003] As a non-contact processing method, laser cutting avoids mechanical stress and reduces glass breakage and edge cracks, so it has gradually been widely used in the field of glass cutting. In the process of glass cutting with a laser cutting machine, first, the original glass plate to be cut is fixed on the workbench to ensure that it is stable and motionless; then, the high-energy laser beam generated by the laser is focused on the surface of the glass to instantly heat the local area to a molten or vaporized state. During the cutting process, auxiliary gas (such as nitrogen or oxygen) is sprayed into the cutting area to remove molten materials and cool the cutting surface, thereby keeping the cutting edge smooth and flat. The control system accurately moves the laser head according to the preset path to complete the cutting of the target shape, and the desired glass product can be obtained.

[0004] In the above-mentioned laser cutting process, the required glass products are cut out efficiently and accurately. However, after the cutting is completed, the glass products and the remaining glass waste are placed together on the workbench and cannot be separated automatically. Manual sorting is required. Manual sorting takes a lot of time and manpower, especially in large-scale production, which becomes a bottleneck in the production process; the sharp edges of the glass may also cause scratches or other work-related accidents during the manual sorting process, which not only reduces production efficiency, but also may increase production costs and safety hazards.

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes a cutting device for laser cutting glass. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problem is as follows: a cutting device for laser cutting glass according to the present invention comprises a workbench and a laser module installed on the workbench;

[0015] A driving assembly is installed on the glass stage and is used to drive the driving gear to make it rotate in a directional manner.

[0016] Preferably, the thickness of the inner wall of the glass carrier above the glass slide is greater than the thickness of the inner wall of the glass carrier below the glass slide, thereby interfering with the upward flipping of the glass slide; a positioning block is fixedly connected to the inner wall of the glass carrier below the glass slide, and the positioning block is connected to the lower end of the glass slide through a telescopic sleeve rod, and a compression spring is also sleeved on the telescopic sleeve rod.

[0019] A driving rack is connected to a rod body of an electric push rod installed on the side wall of the glass stage, and the driving rack is meshed with a driving gear.

[0020] Preferably, the toothed segments and the toothless segments of the driving rack are alternately spaced, and the length of the toothless segments is the same as the horizontal width of each group of glass slides.

[0023] An airflow pipe, wherein the airflow pipe is evenly and fixedly connected to the channel pipe;

[0024] The adsorption plate is composed of a vacuum suction cup at the upper end and a connecting pipe below the vacuum suction cup. The adsorption plate is installed at the upper end of the airflow pipe and is connected to the airflow pipe.

[0025] Preferably, the airflow pipe also includes an extension pipe with a sliding sealing sleeve arranged on the upper end thereof, the extension pipe is connected with the airflow pipe and the connecting pipe, and one end of the extension pipe is fixedly connected with a one-way valve.

At this time, air gradually enters the connecting tube, breaking the vacuum state, so that the glass products can fall off smoothly from the vacuum suction cup, avoiding glass damage caused by sudden pressure release, improving the safety of operation, and greatly reducing the labor intensity of workers, making the collection process of glass products more simple and efficient.

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further explained below in conjunction with the accompanying drawings and specific implementation methods.

[0041] like Figures 1 to 5 As shown, an embodiment of the present invention provides a cutting device for laser cutting glass, comprising a workbench 1, and a laser module 2 installed on the workbench 1;

[0042] Also includes:

[0043] A glass stage 3, which is slidably mounted on the workbench 1, and is a hollow structure with an opening at the top and the same size as the original glass plate;

[0044] Glass slides 4, multiple groups of the glass slides 4 are horizontally laid on the glass stage 3, and the glass slides 4 are flipped downward by the flipping mechanism 5 after the glass cutting is completed;

[0045] Adsorption mechanisms 6 , where a plurality of groups of adsorption mechanisms 6 are evenly installed in the gap between two glass slides 4 in each group, and the adsorption mechanisms 6 are used to adsorb and support the glass products formed after laser cutting on the upper end of the glass slide 3 .

[0046] As an embodiment of the present invention, the flipping mechanism 5 includes:

[0047] A glass-carrying shaft 7, wherein the glass-carrying shaft 7 passes through the glass-carrying plate 4 and is rotatably connected to the inner wall of the glass-carrying platform 3;

[0048] A driving gear 8, wherein the driving gear 8 is fixedly connected to one end of a glass-carrying shaft 7 that passes through the side wall of the glass-carrying platform 3 and extends outward;

[0049] A meshing gear 9, wherein the meshing gear 9 is fixedly connected to one end of another glass-carrying shaft 7 of the same group extending out of the side wall of the glass-carrying platform 3, and meshes with the driving gear 8;

[0050] The driving assembly 10 is installed on the glass stage 3 and is used to drive the driving gear 8 to make it rotate in a directional manner.

[0051] As an embodiment of the present invention, the length of the glass-carrying shaft 7 connected to the driving gear 8 extending outward is greater than the length of another glass-carrying shaft 7 in the same group, and the driving assembly 10 includes:

[0052] A driving gear 14, wherein the driving gear 14 and the driving gear 8 are fixedly connected to the same glass-carrying shaft 7;

[0053] The driving rack 15 is connected to the rod body of an electric push rod 16 installed on the side wall of the glass stage 3 , and the driving rack 15 is meshed with the driving gear 14 .

[0054] Before using the laser module 2 to cut the glass, the adsorption mechanism 6 is started in advance, and together with the horizontal glass carrier 4, the glass original plate is supported to ensure its stability; during the cutting process, the adsorption mechanism 6 continues to work to maintain the stability of the glass and avoid errors caused by vibration. After the cutting is completed, the adsorption mechanism 6 adsorbs and supports the glass products cut by the laser module 2, and the flipping mechanism 5 pushes the driving rack 15 forward through the electric push rod 16 of the driving assembly 10, and the driving rack 15 is meshed with the driving gear 14, so that the driving gear 8 of the same glass carrier shaft 7 rotates together, and then drives the meshing gear 9 to rotate, so that the two horizontally opposed glass carriers 4 are flipped downward at the same time, and the waste glass remaining on the glass carrier 4 is transferred to the inside of the glass carrier 3. Traditional glass cutting may require manual handling of waste materials, and the device reduces manual intervention through automatic flipping and adsorption, speeds up the production rhythm, and significantly improves production efficiency; in addition, the waste glass may have sharp edges after cutting, and manual handling is prone to cause cuts, and the glass carrier 4 is flipped by the flipping mechanism 5 to directly transfer the waste glass to the glass carrier 3, which reduces the chance of personnel contacting the waste glass and improves safety.

[0055] As an embodiment of the present invention, the thickness of the inner wall of the glass carrier 3 above the glass slide 4 is greater than the thickness of the inner wall of the glass carrier 3 below the glass slide 4, thereby interfering with the upward flipping of the glass slide 4; a positioning block 11 is fixedly connected to the inner wall of the glass carrier 3 below the glass slide 4, and the positioning block 11 is connected to the lower end of the glass slide 4 through a telescopic sleeve rod 12, and a compression spring 13 is also sleeved on the telescopic sleeve rod 12.

[0056] During operation, the thickness of the upper part of the inner wall of the glass carrier 3 is greater than that of the lower part. This design prevents the glass carrier 4 from flipping upwards and ensures that it can only flip downwards, thereby accurately transferring the waste glass to the hollow part of the glass carrier 3; in addition, the positioning block 11 is connected to the lower end of the glass carrier 4 through a telescopic sleeve rod 12, and is sleeved with a compression spring 13. This design ensures that when the glass carrier 4 is not flipped, the elastic force of the compression spring 13 can horizontally press the glass carrier 4 against the side wall of the glass carrier 3, and during the flipping process, it can also play a role in precise positioning and buffering to prevent impact and vibration.

[0057] As an embodiment of the present invention, the toothed segments and the toothless segments of the driving rack 15 are alternately spaced, and the length of the toothless segments is the same as the horizontal width of each group of slides.

[0058] When working, the driving rack 15 has alternating toothed sections and toothless sections, and the length of the toothless section is equal to the horizontal width of each group of glass slides, thereby ensuring that the flipping range of the glass slide 4 is limited to prevent excessive rotation. Even if the electric push rod 16 has a telescopic position, it will not exceed the set angle. This design improves the flipping accuracy, prevents damage caused by excessive rotation, and improves operating efficiency and equipment reliability.

[0059] As an embodiment of the present invention, the adsorption mechanism 6 includes:

[0060] A channel tube 17, wherein the channel tube 17 is inserted into the hollow space at the lower end of the glass stage 3 and is connected to a bidirectional diaphragm pump installed in the workbench 1;

[0061] An airflow pipe 18, wherein the airflow pipe 18 is evenly and fixedly connected to the channel pipe 17;

[0062] The adsorption plate 19 is composed of a vacuum suction cup 20 at the upper end and a connecting pipe 21 below the vacuum suction cup 20 . The adsorption plate 19 is installed at the upper end of the airflow pipe 18 and is connected to the airflow pipe 18 .

[0063] As an embodiment of the present invention, the airflow pipe 18 also includes an extension pipe 22 with a sliding sealing sleeve on its upper end. The extension pipe 22 is connected to the airflow pipe 18 and the connecting pipe 21. One end of the extension pipe 22 is fixedly connected to a one-way valve.

[0064] As an embodiment of the present invention, a ventilation hole 23 is opened on the side wall of the connecting tube 21 close to one end of the vacuum suction cup 20, and an unlocking sleeve 24 is provided on the sliding sealing sleeve of the connecting tube 21. The unlocking sleeve 24 is connected to the extension tube 22 through an unlocking spring 25 fixedly connected at the bottom.

[0065] When working, the channel tube 17 is connected to a bidirectional diaphragm pump, which is responsible for generating a vacuum to adsorb the glass. A plurality of air flow pipes 18 branch out from the main channel pipe 17 to transfer the vacuum to each adsorption plate 19; each adsorption plate 19 is composed of a vacuum suction cup 20 and a connecting pipe, the vacuum suction cup 20 directly contacts the glass, and the connecting pipe is responsible for maintaining the vacuum state; during the cutting process, the vacuum suction cup 20 firmly adsorbs the glass, and when the cutting is completed, when the staff needs to collect the glass products, the two-way diaphragm pump introduces high-pressure gas to push the extension tube 22 to move upward, thereby lifting the adsorption mechanism 6, making it easier to take out the glass products, reducing the physical labor and operation difficulty of the staff, and improving the convenience and efficiency of the operation; then the staff operates the unlocking sleeve 24 to make it move under the action of overcoming the elastic force of the spring, thereby opening the ventilation hole 23, at this time, air gradually enters the connecting pipe 21, breaking the vacuum state, so that the glass products can fall off the vacuum suction cup 20 smoothly, avoiding damage to the glass caused by sudden pressure release, improving the safety of the operation, and greatly reducing the labor intensity of the workers, making the collection process of the glass products more simple and efficient.

[0066] As an embodiment of the present invention, a discharge port 26 is provided at the side wall of the lower end of the glass stage 3 , and the bottom of the glass stage 3 is composed of a plurality of inclined planes inclined toward the discharge port 26 .

[0067] As an embodiment of the present invention, the glass stage 3 is slidably connected with a baffle plate 27 at the outer side wall of the discharge port 26 , and the size of the baffle plate 27 is larger than the opening size of the discharge port 26 .

[0068] During operation, during the cutting process, the baffle plate 27 is located at the lowest point and remains closed due to its own gravity, ensuring the cleanliness and safety of the inside of the glass stage 3; after the cutting is completed, the staff slides the baffle plate 27 upward to open it, exposing the discharge port 26, at which time the role of the inclined plane is revealed, guiding the glass fragments to slide toward the discharge port 26, and automatically completing the unloading process; this design not only reduces manual intervention and improves production efficiency, but also reduces the risk of operators contacting glass fragments and ensures safety.

[0069] The above shows and describes the basic principles, main features and significant advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above specific embodiments. Without departing from the spirit and scope of the present invention, the present invention may also be modified and improved to adapt to different usage environments and customer needs.
