Description

Technical Field

[0001] This utility model belongs to the field of tempered glass processing technology, specifically relating to a laser cutting device for tempered glass. Background Technology

[0002] Tempered glass, also known as hardened glass or reinforced glass, is a type of prestressed glass. It is made by using physical or chemical methods to form a compressive stress layer on the surface of ordinary glass. When the glass is subjected to external forces, this compressive stress is first counteracted, thereby increasing the hardness and strength of the glass and enabling it to resist greater impacts and loads.

[0003] Laser cutting is a common process in tempered glass manufacturing. However, existing laser cutting equipment generates glass dust when cutting tempered glass. This dust easily adheres to the laser head or focusing lens of the laser cutter, affecting laser transmission efficiency and focusing accuracy, thereby reducing the cutting quality and processing efficiency.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0028] like Figures 1 to 7As shown, a laser cutting device for tempered glass includes a base plate 1. A first U-shaped plate 2 is fixedly connected to the upper surface of the base plate 1.

A submersible pump 8 is fixedly connected to the inner wall of the water storage box 7. A connecting pipe 9 is fixedly connected to the outlet end of the submersible pump 8 and the bottom of the horizontal tube 3. A second U-shaped plate 10 is fixedly connected to the upper surface of the base plate 1. The upper surface of the second U-shaped plate 10 and the upper surface of the first U-shaped plate 2 are both fixedly connected. A moving mechanism 11 is fixedly connected, and a laser cutter 12 is fixedly connected to the bottom of the moving mechanism 11. A third electric push rod 13 is fixedly connected to the inner wall of the first U-shaped plate 2 and the inner wall of the second U-shaped plate 10. A strip plate 14 is fixedly connected to the bottom of the third electric push rod 13. A scraper 15 is fixedly connected to the bottom of the strip plate 14. A support frame 16 is fixedly connected to the upper surface of the base plate 1. A belt conveyor 17 is fixedly connected to the upper surface of the support frame 16. A second partition plate 18 is fixedly connected to the inner wall of the water storage box 7. A water inlet pipe 32 is fixedly connected to the left side of the water storage box 7. A water outlet pipe 33 is fixedly connected to the left side of the water storage box 7. A valve 34 is fixedly connected to the right end of the water outlet pipe 33.

[0029] The moving mechanism 11 includes a first guide rail 111, a first slider 112, a first electric push rod 113, a second guide rail 114, a second slider 115, a second electric push rod 116, and a mounting plate 117. The upper surfaces of the first U-shaped plate 2 and the second U-shaped plate 10 are both fixedly connected to the bottom of the first guide rail 111. The surface of the first guide rail 111 is slidably connected to the inner wall of the first slider 112. The back of the first slider 112 is fixedly connected to the front of the first electric push rod 113. The bottom of the first electric push rod 113 is fixedly connected to the inner wall of the first slider 112. The upper surface of a guide rail 111 is fixedly connected, the upper surface of a first slider 112 is fixedly connected to the bottom of a second guide rail 114, the surface of the second guide rail 114 is slidably connected to the inner wall of a second slider 115, the right side of the second slider 115 is fixedly connected to the left side of a second electric push rod 116, the bottom of the second electric push rod 116 is fixedly connected to the upper surface of the second guide rail 114, the bottom of the second slider 115 is fixedly connected to the upper surface of a mounting plate 117, and the bottom of the mounting plate 117 is fixedly connected to the upper surface of a laser cutter 12.

[0030] The strip plate 14 has a circular hole 28 inside. A pressing block 29 is attached to the inner wall of the circular hole 28. A fifth electric push rod 30 is fixedly connected to the upper surface of the pressing block 29. A third U-shaped plate 31 is fixedly connected to the upper surface of the strip plate 14. The inner wall of the third U-shaped plate 31 is fixedly connected to the upper surface of the fifth electric push rod 30.

[0031] It should be noted that the internal space of the horizontal tube 3 is divided into two parts by the first partition plate 6. When the submersible pump 8 is started, the water in the water storage box 7 first enters the connecting pipe 9 through the submersible pump 8. Then, the water in the connecting pipe 9 enters the horizontal tube 3 and is sprayed out through the nozzle 5 at the bottom of the liquid distribution pipe 4. At this time, when the glass on the belt conveyor 17 passes under the nozzle 5, the water sprayed out by the nozzle 5 can cover the glass surface with a water film, and the water film can suppress the diffusion of glass dust generated during cutting.

[0032] The first guide rail 111 and the first slider 112 work together to make the second guide rail 114 move only forward and backward. The first electric push rod 113 controls the forward and backward movement of the second guide rail 114. The second guide rail 114 and the second slider 115 work together to make the mounting plate 117 move only left and right. The second electric push rod 116 controls the left and right movement of the mounting plate 117.

[0033] The scraper 15 can be moved up or down by the third electric push rod 13. When the distance between the scraper 15 and the belt conveyor 17 is less than the thickness of the glass, the scraper 15 can limit the glass conveyed on the belt conveyor 17. When the scraper 15 contacts the upper surface of the glass, the water film on the glass can be automatically scraped off by the scraper 15 as the glass moves to the right through the belt conveyor 17. The scraped water enters the water storage box 7.

[0034] Clean water can be injected into the water storage box 7 through the inlet pipe 32. The outlet pipe 33 is controlled by the valve 34. When it is necessary to drain the water in the water storage box 7, the water in the water storage box 7 can be drained through the outlet pipe 33 by opening the valve 34.

[0035] The fifth electric push rod 30 can control the pressing block 29 to move up or down. When the glass moves to the appropriate position, the fifth electric push rod 30 can press the pressing block 29 against the glass, and the pressing force will prevent the glass from moving during the cutting process.

[0036] like Figures 1 to 9 As shown, the second partition plate 18 has a water passage hole 19 inside, and rectangular holes 20 are provided on both the front and rear sides of the water storage box 7. A rectangular frame 21 is attached to the inner wall of the rectangular hole 20 and the right side of the second partition plate 18. A filter screen 22 is fixedly connected to the inner wall of the rectangular frame 21. A baffle 23 is fixedly connected to the front of the rectangular frame 21. The back of the baffle 23 is attached to the front of the water storage box 7. A sealing plate 24 is fixedly connected to the back of the water storage box 7. The front of the sealing plate 24 is attached to the back of the rectangular frame 21. A handle 25 is fixedly connected to the front of the baffle 23. A limit block 26 is attached to the front of the baffle 23. A fourth electric push rod 27 is fixedly connected to the side of the limit block 26 and the front of the water storage box 7.

[0037] The filter screen 22 is located to the right of the water passage hole 19. The filter screen 22 is made of stainless steel and has a hole diameter of 1mm.

[0038] It should be noted that the combination of baffle 23, handle 25, limit block 26 and fourth electric push rod 27 makes it easy to assemble and disassemble the rectangular frame 21 and the water storage box 7. By setting a filter screen 22 at the water passage hole 19, the wastewater on the right side of the second partition plate 18 needs to be filtered through the filter screen 22 before it can diffuse to the left side of the second partition plate 18 through the water passage hole 19. At the same time, by setting a water passage hole 19 on the second partition plate 18, the wastewater generated during hole cutting can be reused in the submersible pump 8, thereby reducing the water consumption of the laser hole cutting equipment. After the rectangular frame 21 is fixed in the rectangular hole 20, the connection between the rectangular frame 21 and the rectangular hole 20 can be sealed by the baffle 23 and the sealing plate 24.

[0039] The working principle of this utility model is as follows: First, water is injected into the water storage box 7 through the water inlet. After the water level in the water storage box 7 reaches a suitable height, the water injection into the water storage box 7 is stopped. Then, the submersible pump 8 is started so that the water in the water storage box 7 is sprayed out through the nozzle 5. If the water sprayed out by the nozzle 5 does not spray onto the glass, it directly enters the water storage box 7.

[0040] When cutting holes in the glass, first move the third electric push rod 13 so that the distance between the scraper 15 and the belt conveyor 17 is less than the thickness of the glass. Then, place the glass on the belt conveyor 17 on the left side of the first U-shaped plate 2 and transport the glass to the right through the belt conveyor 17. After the glass passes under the nozzle 5, the water sprayed by the nozzle 5 can cover the glass surface with a layer of water film.

[0041] When the glass comes into contact with the scraper 15, the scraper 15 limits the glass and shuts off the belt conveyor 17. Then, the fifth electric push rod 30 causes the pressing block 29 to press the glass. At this time, the pressing force prevents the glass from moving during the cutting process. Then, the first electric push rod 113 and the second electric push rod 116 on the moving mechanism 11 control the horizontal movement of the laser cutter 12 and laser-cuts the glass. During the cutting process, the water film can suppress the diffusion of glass dust generated during cutting.

[0042] After the glass is cut, the laser cutter 12 is turned off, and the laser cutter 12 is returned to its initial position by the first electric push rod 113 and the second electric push rod 116. Then, the pressing block 29 is stopped from pressing the glass by the fifth electric push rod 30, and the distance between the scraper 15 and the belt conveyor 17 is equal to the glass thickness by the third electric push rod 13, so that the scraper 15 no longer limits the glass. Then, the belt conveyor 17 is turned on, and the glass continues to be transported to the right by the belt conveyor 17. At the same time, the water film on the glass surface can be scraped off by the scraper 15, and the scraped water directly enters the water storage box 7. Meanwhile, the wastewater on the right side of the second partition plate 18 needs to be filtered by the filter screen 22 before it can diffuse to the left side of the second partition plate 18 through the water passage hole 19.

[0043] When the filter screen 22 needs to be cleaned, first drain the water in the water storage box 7. Then, use the fourth electric push rod 27 to separate the limiting block 26 from the baffle 23. Then, pull the handle 25 to pull the rectangular frame 21 out of the rectangular hole 20. After the filter screen 22 is cleaned, insert the rectangular frame 21 back into the rectangular frame 22. Use the fourth electric push rod 27 to make the limiting block 26 contact the baffle 23. At this time, the rectangular frame 21 is fixed in the rectangular hole 20 by the cooperation of the limiting block 26 and the baffle 23. The connection between the rectangular frame 21 and the rectangular hole 20 is sealed by the baffle 23 and the sealing plate 24.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
