Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, and in particular relates to a drilling device for glass cover plate production. Background Technology

[0002] Mobile phone cover glass, also known as mobile phone protective glass or mobile phone touch screen glass, is a key protective component on the outer layer of the display screen of smartphones and other mobile devices. It covers the display screen directly, protecting it from physical damage such as scratches and impacts, and also serving as the direct interface for users to interact with the phone via touch. Drilling is an indispensable step in the production process of the cover glass.

[0003] However, existing drilling devices have some drawbacks in practical applications. Among them, the position of the electric suction cup is usually inconvenient to fix, lacks flexibility and adjustability, and is difficult to adapt to glass covers of different sizes. This may cause loosening or displacement during suction fixation, which in turn affects the accuracy of drilling. In addition, during the drilling operation, the water used for rinsing and cooling lacks guidance and restraint, and the direction of water flow is difficult to control. It often flows down randomly from all sides of the machine, causing a dirty and messy working environment and increasing the difficulty of subsequent cleaning.

[0004] Therefore, there is a particular need for a drilling device for glass cover production to solve the above problems. Utility Model Content

The drilling assembly is located on the upper part of the column 3. Two guide rails 13 are arranged side by side and bolted to the top of the machine base 2. The placement platform 14 is slidably mounted on the top of the machine base 2. Between the two guide rails 13, a handle 141 is welded to the middle of the front of the placement platform 14. Four electric suction cups 15 are arranged diagonally in an X-shape and are slidably mounted on the placement platform 14. Two bidirectional lead screws 16 are distributed in an up-down cross pattern and are rotatably mounted inside the placement platform 14. Both ends of each bidirectional lead screw 16 extend to the outside of the placement platform 14. Each knob 17 is welded to the front end of each bidirectional lead screw 16. The four electric suction cups 15 are threadedly engaged with the two bidirectional lead screws 16 respectively. The drain pipe 22 is welded to the front of the machine base 2, and its upper end passes through the machine base 2 and is flush with its top surface, directly connecting to the water storage area. The water spray assembly is located between the frame 1 and the machine base 2. The controller 23 is bolted to the lower right side of the column 3 and is electrically connected to the electric suction cups 15.

[0019] like Figure 1 and Figure 2 As shown, the drilling assembly includes guide rods 4, servo motors 5, one-way lead screws 6, slide plates 7, motors 8, threaded rods 9, guide pillars 91, moving plates 10, drive motors 11, and drill bits 12. Two guide rods 4 are vertically bolted to the upper front side of the column 3. The servo motor 5 is bolted to the upper right front side of the column 3, with its output shaft facing left. The right end of the one-way lead screw 6 is welded to the output shaft of the servo motor 5 via a coupling, and both its left and right ends are rotatably engaged with the column 3. The slide plate 7 is threaded onto the outside of the one-way lead screw 6 and slidably connected to the two guide rods 4. The motor 8 is bolted to... The upper front side of the slide plate 7 is connected with its output shaft facing downwards. The upper end of the threaded rod 9 is welded to the output shaft of the motor 8 through a coupling. Both its upper and lower ends are rotatably engaged with the slide plate 7. Two guide pillars 91 are bolted side by side to the front side of the slide plate 7. The moving plate 10 is threaded on the outside of the threaded rod 9 and is slidably connected to the two guide pillars 91. The drive motor 11 is bolted to the front side of the moving plate 10 with its output shaft facing downwards. The servo motor 5, the motor 8 and the drive motor 11 are all electrically connected to the controller 23. The drill bit 12 is welded to the output shaft of the drive motor 11 through a coupling.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, the water spray assembly includes a metal hose 18, a water supply pipe 19, a water pump 20, a water tank 21, and an inlet pipe 211. The water tank 21 is bolted to the rear of the frame 1, and the inlet pipe 211 is welded to the top of the water tank 21. The water pump 20, which is electrically connected to the controller 23, is bolted to the top right side of the water tank 21. Its pumping end extends to the left into the interior of the water tank 21, while its delivery end faces right. The rear end of the water supply pipe 19 is welded to the delivery end of the water pump 20. The lower end of the metal hose 18 is welded to the upper end of the water supply pipe 19 and is supported by a rectangular support block set on the right side of the machine base 2. The outlet end of the metal hose 18 is connected to a conical nozzle. The diameter of the conical nozzle gradually decreases along the water flow direction, creating a streamlined appearance that can concentrate the water flow and enhance the accuracy of the water spray.

[0021] When this device is needed to drill holes in a glass cover, the operator first inputs the pre-set drilling program into the controller 23, then holds the handle 141 and pulls the placement platform 14 forward, and rotates the two bidirectional screws 16 clockwise in sequence. Driven by the two bidirectional screws 16, the four electric suction cups 15 move inward synchronously until they are adjusted to a suitable position to fit glass covers of different sizes. Then, the glass cover to be drilled is placed on the four electric suction cups 15. The controller 23 sends a command to control the four electric suction cups 15 to generate suction and firmly adhere the glass cover. Then, the placement platform 14 is pushed back, and clean water is added to the water tank 21 from the water inlet pipe 211. Then, the metal hose 18 is bent so that its conical nozzle is aimed at the area of ​​the glass cover to be drilled.

[0022] After waiting for a period of time to ensure that all preparations are complete, the controller 23 issues a command to control the servo motor 5 to start running, so that its output shaft drives the one-way screw 6 to rotate clockwise or counterclockwise, thereby driving the slide plate 7 to move all the components set on it to the left or right until the drill bit 12 is aligned with the position of the glass cover plate to be drilled from above. Once aligned, the controller 23 immediately controls the servo motor 5 to stop running, and simultaneously controls the motor 8 and drive motor 11 to start running. When the motor 8 is running, its output shaft drives the threaded rod 9 to rotate clockwise, driving the moving plate 10 to move all the components set on it to descend, so that the drill bit 12 gradually approaches the glass cover plate. When the drive motor 11 is running, its output shaft drives the drill bit 12 to rotate at high speed. When the drill bit 12 descends to a suitable height and contacts the glass cover plate, it drills a hole in the glass cover plate.

[0023] During the drilling process, the controller 23 starts the water pump 20. After the water pump 20 starts running, it quickly draws out the clean water in the water tank 21 and sends the clean water into the water pipe 19. Finally, the clean water is sprayed out from the metal hose 18 to the drilling area to rinse and cool the drill bit 12 and the glass cover plate, reduce the temperature of the drill bit 12 and reduce wear, and at the same time wash away the debris generated by drilling. The water after use is collected in the water storage area of ​​the machine 2 and then discharged smoothly through the drain pipe 22.

[0024] After the drilling is completed, the drive motor 11 and water pump 20 stop running, and the output shaft of motor 8 begins to rotate counterclockwise, driving the moving plate 10 to lift all the components set on it, completing one drilling operation. At this time, the controller 23 issues a command to control the four electric suction cups 15 to contact the adsorption state, and the glass cover can be removed from the four electric suction cups 15.
