The first sliding module is used to drive the cover plate mounting plate to slide back and forth; the second sliding module is used to drive the drill bit assembly to slide left and right.

[0005] In the aforementioned hole-opening equipment for processing glass cover plates, the nozzle assembly includes a first clamp and a nozzle pipe.

The drill head is located at the output end of the drill bit body, and all the nozzle assemblies are disposed on the drill bit body.

[0007] In the aforementioned glass cover plate processing hole-making equipment, the first sliding module includes a track frame, with vertical slide rails arranged on both sides of the track frame along its length direction. A first lead screw is arranged between the two vertical slide rails on the track frame, and the two ends of the first lead screw are respectively rotatably connected to the track frame.

To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0016] In the description of this utility model, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this utility model based on the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0017] Please see Figures 1 to 3 This utility model provides a drilling device for processing glass cover plates, including a first sliding module 1, on which a cover plate mounting plate 2 is slidably connected. A second sliding module 3 is disposed above the cover plate mounting plate 2, and a vertically movable drill bit assembly 4 is slidably connected to the second sliding module 3. The output end of the drill bit assembly 4 is provided with a drill head 41. A three-degree-of-freedom motion system is constructed by the first sliding module 1 and the second sliding module 3 combined with the lifting posture of the drill bit assembly 4. The first sliding module 1 is responsible for providing linear movement capability in the horizontal direction to adjust the position of the cover plate mounting plate 2 in the Y-axis direction, thereby realizing the positioning of the drill bit assembly 4 in the Y-axis direction. The second sliding module 3 provides displacement in the X-axis direction, ensuring that the drill bit assembly 4 can flexibly adjust its position in this direction. The lifting mechanism of the drill bit assembly 4 provides the third degree of freedom control capability for the drill bit assembly 4 through movement in the Z-axis direction. The combination of these three degrees of freedom allows the drill assembly 4 to flexibly adjust its drilling position on the glass cover plate within a specified workspace according to processing requirements, thereby meeting high processing requirements.

[0018] In this embodiment, the drill bit assembly 4 has multiple nozzle assemblies 5 arranged in a ring around the drill head 41, with the water outlet end of the nozzle assembly 5 facing the end of the drill head 41. The first sliding module 1 is used to drive the cover plate mounting plate 2 to slide back and forth; the second sliding module 3 is used to drive the drill bit assembly 4 to slide left and right. By setting the nozzle assembly 5 in a ring matrix, the nozzle assembly 5 forms an overlapping spray area around the drill head 41 when spraying liquid, so that the coolant forms a uniform liquid film at the end of the drill head 41, eliminating hot spots due to temperature differences. The coolant also forms a liquid film in the drilling area of ​​the glass cover plate, effectively reducing the working temperature of the glass cover plate.

[0019] like Figures 1 to 3As shown, the nozzle assembly 5 further includes a first clamp 51 and a nozzle 52. The first clamp 51 is disposed on the drill bit assembly 4, and the nozzle 52 is detachably connected to the first clamp 51. The water outlet end of the nozzle 52 is bent toward the end of the drill head 41. The first clamp 51 enables a detachable connection between the nozzle 52 and the drill bit assembly 4, allowing the user to periodically maintain or replace the nozzle 52, avoiding clogging after long-term use. In addition, the bending of the water outlet end of the nozzle 52 toward the end of the drill head 41 increases the contact area between the coolant and the drill head 41, effectively improving the cooling effect on the drill head 41.

[0020] It should be noted that the first clamping component 51 includes two clamping parts, one end of which is hinged to each other, and a clamping groove that matches the shape of the nozzle 52 is formed between the two clamping parts. The two clamping parts are locked together by bolts. The first clamping component 51 is an existing clamping structure. The specific structure and working principle are existing technologies and will not be described in detail here.

[0021] like Figures 1 to 3 As shown, the drill bit assembly 4 further includes a third sliding module 42 and a drill bit body 43. The third sliding module 42 is slidably connected to the second sliding module 3. A second clamp 44 is provided on the third sliding module 42, and the second clamp 44 is slidably connected to the third sliding module 42. The drill bit body 43 is detachably connected to the second clamp 44. The third sliding module 42 is used to drive the drill bit body 43 to slide up and down. The drill head 41 is located at the output end of the drill bit body 43, and all the nozzle assemblies 5 are disposed on the drill bit body 43. In this embodiment, the second clamp 44 is used to realize the detachable connection between the drill bit body 43 and the third sliding module 42, so that the user can perform regular maintenance on the drill bit assembly 4, reducing the maintenance difficulty for the user. The first sliding module 1, the second sliding module 3, and the third sliding module 42 together form a three-degree-of-freedom motion mechanism, allowing the drill bit body 43 to adjust the drilling position arbitrarily within the three degrees of freedom in conjunction with the cover plate mounting plate 2.

[0022] It should be noted that the second clamp component 44 is an existing clamp structure, and its specific structure and working principle are existing technologies, which will not be described in detail here.

[0023] like Figures 1 to 3As shown, the first sliding module 1 further includes a track frame 11, with vertical slide rails 12 arranged on both sides of the track frame 11 along its length direction. A first lead screw 13 is arranged between the two vertical slide rails 12 on the track frame 11, and the two ends of the first lead screw 13 are respectively rotatably connected to the track frame 11. A first motor 14 is arranged on the track frame 11 and is drivenly connected to the first lead screw 13. Slider blocks 15 are respectively arranged on both sides of the bottom of the cover plate mounting plate 2 and are slidably connected to the vertical slide rails 12. A lead screw nut is arranged at the bottom of the cover plate mounting plate 2 and is drivenly connected to the first lead screw 13. During operation, the first motor 14 drives the first lead screw 13 to rotate, and the lead screw nut slides along the length direction of the first lead screw 13 to drive the cover plate mounting plate 2 to slide in the Y-axis direction, thereby adjusting the position of the glass cover plate and the drill bit assembly 4 in the Y-axis direction, and realizing the movement requirements of the cover plate mounting plate 2.

[0024] like Figures 1 to 3 As shown, the second sliding module 3 further includes a transverse slide rail 31. The two ends of the transverse slide rail 31 are respectively connected to the two sides of the first sliding module 1 through the vertical plate 32. A second lead screw 33 is provided on the transverse slide rail 31 along its length direction. The two ends of the second lead screw 33 are respectively rotatably connected to the transverse slide rail 31. A second motor 34 is provided on the transverse slide rail 31 and is drivenly connected to the second lead screw 33. The bottom of the drill bit assembly 4 is slidably connected to the transverse slide rail 31, and the drill bit assembly 4 is drivenly connected to the second lead screw 33. During operation, the second motor 34 drives the second lead screw 33 to rotate. When the second lead screw 33 rotates, it drives the drill bit assembly 4 to slide in the X-axis direction, thereby adjusting the position of the glass cover plate and the drill bit assembly 4 in the X-axis direction, realizing the movement requirements of the drill bit assembly 4.

[0025] It should be noted that the bottom of the drill bit assembly 4 is connected to the second lead screw 33 via a lead screw nut. In addition, the bottom of the drill bit assembly 4 is also provided with a slider that is slidably connected to the transverse slide rail 31.

[0026] like Figures 1 to 3As shown, further, the third sliding module 42 includes a longitudinal slide rail 421 and a sliding plate 422. The longitudinal slide rail 421 is slidably connected to the second sliding module 3. A third lead screw 423 is provided on the longitudinal slide rail 421 along its length direction. The two ends of the third lead screw 423 are respectively rotatably connected to the longitudinal slide rail 421. A third motor 424 is provided on the longitudinal slide rail 421 and is drivenly connected to the third lead screw 423. The sliding plate 422 slides with the longitudinal slide rail 421. The slide plate 422 is connected to the third lead screw 423 via a transmission connection; the drill bit body 43 is mounted on the slide plate 422 via the second clamp 44; during operation, the third motor 424 drives the third lead screw 423 to rotate, and the third lead screw 423 drives the slide plate 422 to slide along the length direction of the longitudinal slide rail 421, thereby driving the drill bit body 43 to slide in the Z-axis direction to adjust the position of the glass cover plate and the drill bit assembly 4 in the Z-axis direction, thus realizing the movement requirements of the drill bit body 43.

[0027] It should be noted that the bottom of the slide plate 422 is connected to the third lead screw 423 via a lead screw nut. In addition, the bottom of the slide plate 422 is also provided with a slider that is slidably connected to the longitudinal slide rail 421.

[0028] like Figures 1 to 3 As shown, the first sliding module 1 is further provided with a protective housing 6, and a working cavity 61 is provided inside the protective housing 6. The second sliding module 3 and the drill bit assembly 4 are both located inside the working cavity 61. By providing the protective housing 6, glass fragments or powder generated during the processing of the glass cover are prevented from splashing into the environment, thus improving the safety of the equipment during use.

[0029] like Figures 1 to 3 As shown, the protective housing 6 is further provided with a flip cover 62, which is hinged to the protective housing 6. The flip cover 62 facilitates the user to maintain or operate the components in the working cavity 61, and also facilitates the user to load the glass cover onto the cover mounting plate 2.

[0030] In summary, by arranging the nozzle assembly 5 in a ring matrix, overlapping spray zones are formed around the drill head 41 during liquid spraying. This arrangement ensures that the coolant covers the entire end area of ​​the drill head 41 during spraying, forming a uniformly distributed coolant film. This film helps eliminate hot spots caused by insufficient local cooling, maintaining a balanced temperature of the drill head 41. Simultaneously, the sprayed coolant also forms a continuous film on the surface of the drilling area of ​​the glass cover. This film effectively conducts heat, continuously carrying away the heat generated during drilling, thereby effectively reducing the operating temperature of the glass cover and ensuring the stability of the processing and product quality.
