Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, and particularly relates to an underwater drilling device for improving the smoothness of the glass hole wall. Background Art

[0002] As a material widely used in many fields such as construction, automobiles, and electronic devices, glass often needs to be drilled to meet various practical needs. For example, in the field of building curtain walls, glass needs to be drilled to install connectors; in automobile manufacturing, window glass needs to be drilled for installing lifting devices, etc.; the display glass of electronic devices may also need to be drilled to place various sensors or buttons.

[0003] The traditional method for drilling glass is mechanical drilling. During mechanical drilling, the drill bit rotates at high speed and rubs against the glass to generate heat, which easily causes local overheating of the glass, resulting in thermal stress cracks, reducing the strength and stability of the glass. At the same time, due to the lack of effective cooling, glass chips are easily adhered to the hole wall, causing the hole wall to be rough. With the continuous improvement of the quality requirements for glass products, especially in some high-end application scenarios such as precision optical instruments and high-end electronic product displays, the requirements for the smoothness of the glass hole wall are becoming increasingly stringent. Therefore, the underwater drilling technology has emerged. By placing the glass in water for drilling, water can absorb a part of the heat and relieve the thermal stress problem to a certain extent. However, the glass chips during the drilling process are still easily adhered to the hole wall, resulting in a rough hole wall and unable to obtain a relatively smooth hole groove. Summary of the Invention

[0004] In view of this, the present invention proposes an underwater drilling device for improving the smoothness of the glass hole wall, which changes the viscosity of the liquid at the glass cutting position by injecting a thickening agent and pressurizing, so that during drilling, the chips can be wrapped to avoid scratching the glass.

Specific embodiments

[0025] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention will be further described in conjunction with the accompanying drawings.

[0026] See Figures 1 to 4, an underwater hole - opening device for improving the smoothness of the glass hole wall provided by the present invention includes a processing water tank 1, a bearing frame 2, a top plate 3, support columns 4, and an underwater hole - opening mechanism. The top surface of the processing water tank 1 is open. The bearing frame 2 is arranged on the inner wall of the processing water tank 1 and is used for placing the glass to be drilled. The top plate 3 is located above the processing water tank 1. The support columns 4 connect the top surface of the processing water tank 1 and the bottom surface of the top plate 3. The underwater hole - opening mechanism includes a first electric push rod 5, a lower pressure plate 6, a connecting pipe 7, a top - surface suction cup 8, a second electric push rod 9, a mounting plate 10, a motor 11, a drill rod 12, a storage tank 13, an electric injection head 14, a liquid - adding pipe 15, a booster pump 16, a booster pipeline 17, and a main control unit 18. The first electric push rod 5 is arranged on the bottom surface of the top plate 3, and its output shaft is connected to the top surface of the lower pressure plate 6. The top end of the connecting pipe 7 is connected to the bottom surface of the lower pressure plate 6, and its bottom end is connected to the top of the top - surface suction cup 8. The second electric push rod 9 is arranged inside the connecting pipe 7, and its output shaft is connected to the top surface of the mounting plate 10. The motor 11 is arranged on the bottom surface of the mounting plate 10, and its output shaft is connected to the top end of the drill rod 12. The storage tank 13 is arranged on the bottom surface of the lower pressure plate 6 and stores a thickening liquid inside. The electric injection head 14 is embedded in the outer wall of the top - surface suction cup 8. The liquid - adding pipe 15 connects the storage tank 13 and the electric injection head 14. The booster pump 16 is arranged on the bottom surface of the lower pressure plate 6. The booster pipeline 17 connects the booster pump 16 and the outer wall of the top - surface suction cup 8. The main control unit 18 is arranged on the top surface of the top plate 3 and is electrically connected to the first electric push rod 5, the second electric push rod 9, the motor 11, the electric injection head 14, and the booster pump 16 respectively.

[0027] The top of the processing water tank 1 is open, and water can be directly injected into the processing water tank 1. A bearing frame 2 is arranged on the inner side wall of the processing water tank 1. The outer wall of the bearing frame 2 is connected to the inner side wall of the processing water tank 1 and can be used for placing the glass to be drilled. The glass to be drilled is placed into the water - filled processing water tank 1, and the edge of the glass can contact the top surface of the bearing frame 2 for support. Then, the first electric push rod 5 can lower the lower pressure plate 6. During the descent of the lower pressure plate 6, the top - surface suction cup 8 can cover the position where the glass is to be opened. When drilling, the second electric push rod 9 can drive the motor 11 and the drill rod 12 to descend synchronously through the mounting plate 10. During the descent, the motor 11 can drive the drill rod 12 to rotate, and the drill rod 12 can perform rotary hole - opening on the glass. Since there is water in the top - surface suction cup 8, the water can absorb part of the heat, relieve the thermal stress problem, prevent the glass from cracking, and at the same time, it can also prevent the glass chips from splashing randomly, which is convenient for cleaning.

[0028] When the top suction cup 8 covers the top surface of the glass, the electric injection head 14 can be turned on. The electric injection head 14 injects the thickening liquid in the storage tank 13 into the inside of the top suction cup 8 through the liquid adding pipe 15. The thickening liquid is mixed with the water in the top suction cup 8. At this time, the viscosity of the mixed liquid will increase. At the same time, a booster pump 16 is provided on one side of the bottom surface of the lower pressing plate 6. The booster pump 16 can pressurize the mixed liquid in the top suction cup 8 through the pressurization pipeline 17. After the mixed liquid is pressurized, its viscosity will further increase. When the drill rod 12 drills the glass, the glass debris can be wrapped by the viscous liquid and will not contact the glass surface and the hole groove during the drilling process, so that the smoothness of the hole wall can be improved and the quality of glass processing can be improved. The thickening liquid is one of polyacrylamide, silicone oil or sodium dodecyl sulfate, etc. After mixing the thickening liquid with water, a mixed liquid with a higher viscosity is obtained. The mixed liquid can better adhere to the glass surface and play a dual role similar to that of a lubricant and a coolant. And the viscosity of the mixed liquid can be changed by pressurization to facilitate the adaptation to different properties of glass and different hole opening requirements.

[0029] Preferably, the underwater hole opening mechanism further includes a first electric slide table 19 and a moving plate 20. The first electric slide table 19 is arranged on the bottom surface of the top plate 3, and the bottom surface of its moving part is connected to the top surface of the moving plate 20. The first electric push rod 5 is arranged on the bottom surface of the moving plate 20. The main control unit 18 is electrically connected to the first electric slide table 19.

[0030] The first electric slide table 19 can drive the first electric push rod 5 to move through the moving plate 20, so as to drive the top suction cup 8 to move through the lower pressing plate 6 and the connecting pipe 7. The top suction cup 8 can then move above the position of the glass to be drilled. The first electric slide table 19 is in a vertical and horizontal combination mode, and can drive the top suction cup 8 to move above any position of the glass.

[0031] Preferably, the underwater hole opening mechanism further includes a bottom suction cup 21, a waste discharge pipe and a collection box 22.

[0032] After the top suction cup 8 covers above the position of the glass to be drilled, the bottom suction cup 21 can also cover below the position to be drilled, so as to protect the top and bottom surfaces of the glass.

[0034] After the top suction cup 8 is fixed to the specified position, the second electric sliding table 30 can be turned on. The second electric sliding table 30 can drive the synchronous pipe 25 to move synchronously, so that the bottom suction cup 21 can move below the top suction cup 8. Then, the third electric push rod 29 is started. The third electric push rod 29 drives the lifting pipe 23 to rise through the force-bearing plate 28, so that the bottom suction cup 21 covers the bottom surface of the glass to achieve sealing. At this time, the hole-opening process of the glass can be carried out. After the drilling is completed, the solenoid valve 27 can be opened. The liquid and debris in the top suction cup 8 can flow into the bottom suction cup 21 through the hole grooves of the glass, and then pass through the lifting pipe 23, the first corrugated pipe 24, the synchronous pipe 25, and the second corrugated pipe 26 in sequence and be discharged into the collection box 22 for collection. Similar to the first electric sliding table 19, the second electric sliding table 30 adopts a combination of vertical and horizontal directions to facilitate driving the bottom suction cup 21 to move to any position on the bottom surface of the glass.

The filter screen 32 includes a polymer filter screen and other filter screens, which can filter the thickened liquid and debris. The filtered water can enter the lower part of the collection box 22. After the circulation pump 33 is turned on, the circulation pump 33 can pump out the clean water below the collection box 22 through the water suction pipe 34 and re-inject it into the processing water tank 1 through the circulation pipeline 35 to realize the recycling of water resources.

[0039] Preferably, an opening door 36 is arranged on the side wall of the collection box 22.
