It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0027] Please refer to the attached Figure 1 and attached Figure 3 A drilling device for tempered glass processing includes a base 1, a mobile loading frame 2 is installed on the base 1, and a drilling mechanism 3 slides on the mobile loading frame 2. A controller 4 is also installed on the mobile loading frame 2 for controlling the mobile loading frame 2 and the drilling mechanism 3 to work, so as to drill preset drilling points on the curved glass 7.

[0028] Please refer to the attached Figure 2The drilling mechanism 3 includes a hydraulic cylinder 31 connected to the moving end of the mobile loading frame 2. When the mobile loading frame 2 controls the moving end to move horizontally, the moving end drives the hydraulic cylinder 31 to move synchronously. A fixed frame 32 is installed at the telescopic end of the hydraulic cylinder 31, and a drilling device 33 is rotatably connected to the fixed frame 32 through a rotating shaft. A first motor 34 is installed on the fixed frame 32, and the output shaft of the first motor 34 is fixedly connected to the drilling device 33. A drilling head 35 is detachably connected to the rotating end of the drilling device 33. In this embodiment, when the first motor 34 rotates, it drives the drilling device 33 to rotate a certain angle, thereby changing the angle between the drilling head 35 and the curved glass 7, so that the drilling head 35 and the surface of the curved glass 7 remain vertical, thereby facilitating the drilling head 35 to drill the curved glass 7.

[0029] Among them, the mobile loading frame 2, the hydraulic cylinder 31, the drilling equipment 33, the first motor 34 and the drilling head 35 are all existing technologies well known to people in this field, and the specific working principles will not be described in detail here.

[0030] Specifically, first electric push rods 36 are installed on both sides of the rotating end of the drilling device 33, and first grinding heads 37 are installed at the telescopic ends of the first electric push rods 36. In this embodiment, when the first electric push rods 36 perform telescopic movements, the first grinding heads 37 can be controlled to perform synchronous telescopic movements, so that the distance between the first grinding heads 37 can be adjusted to adapt to the diameter of the drilling head 35. When the first grinding heads 37 are fully retracted, the outermost spacing of the first grinding heads 37 is smaller than the diameter of the drilling head 35.

[0031] When the drilling device 33 drives the drilling head 35 to rotate, it drives the first grinding head 37 to rotate synchronously, so as to grind the top edge of the drilling hole, thereby avoiding scratches on the operator's hands when the edge of the drilling hole is broken, and improving the flatness of the edge of the drilling hole. Among them, the spacing parameters of the first grinding head 37 can be pre-set by the controller 4 before drilling, so as to facilitate grinding processing of the drilling position.

[0032] It should be noted that the curved glass 7 is drilled by the drilling head 35. After the drilling is completed, the drilling head 35 is continuously rotated, so that the first grinding head 37 is continuously rotated to grind the edge of the drilling position, thereby avoiding scratches on the operator's hands by glass fragments at the drilling position during drilling.

[0033] The base 1 is also provided with a suction cup fixture 5 for clamping and fixing the curved glass 7, so that the drilling mechanism 3 can drill the curved glass 7, so that the curved glass 7 remains stable during the drilling operation; for details, please refer to the attached Figure 4The suction cup clamp 5 includes a fixed seat 51 installed on both sides of the base 1, and a positioning frame 52 is provided above the fixed seat 51, a support rod 53 is provided between the positioning frame 52 and the fixed seat 51, and the two ends of the support rod 53 are respectively rotatably connected with the fixed seat 51 and the positioning frame 52 through a rotating shaft, and a plurality of positioning suction cups 54 are installed on the positioning frame 52 for clamping and fixing the curved glass 7, and an adjusting cylinder 55 is also provided between the fixed seat 51 and the positioning frame 52, and the adjusting cylinder 55 is rotatably connected to the fixed seat 51 through a rotating shaft, and the telescopic end of the adjusting cylinder 55 is rotatably connected to the positioning frame 52 through a rotating shaft.

[0034] It should be understood that by adjusting the cylinder 55 to perform telescopic movement, the positioning frame 52 is controlled to move synchronously. Under the limiting action of the support rod 53, the orientation position of the positioning frame 52 can be adjusted, so that when the curved glass 7 is assembled, it is convenient to fix the curved glass 7. In this embodiment, the suction cup clamp 5 is an existing technology well known to people in this field, and the specific working principle will not be described in detail here.

A second electric push rod 69 is also installed on the rotating table 63, and the telescopic end of the second electric push rod 69 is fixedly connected to the connecting block 68. In this embodiment, when the second electric push rod 69 performs telescopic movement, the connecting rod 67 is controlled to move synchronously. Under the action of the rotating shaft connection, the multiple second grinding heads 66 are controlled to move, thereby facilitating the mutual adaptation of the diameter sizes at the drilling positions and grinding the drilled holes.

[0036] Among them, a second motor 610 is also installed on the support frame 62, and the output shaft of the second motor 610 is connected to the rotating table 63 through a pulley transmission mechanism 611. When the second motor 610 rotates, the rotating table 63 is driven to rotate through the pulley transmission mechanism 611, so as to facilitate driving the second grinding head 66 to grind the edge of the drill hole.

[0037] For details, please refer to the attached Fig. 9 , sleeve rods 612 are provided around the grinding table 64, and the sleeve rods 612 are fixedly connected to the support frame 62, an insertion rod 613 is slidably connected inside the sleeve rod 612, and a support suction cup 614 is installed at one end of the insertion rod 613 away from the sleeve rod 612, and a spring 615 is also installed between the sleeve rod 612 and the insertion rod 613. In this embodiment, the support suction cup 614 is used to position and support the curved glass 7 to avoid the curved glass 7 from being broken at the drilling position when drilling, thereby improving safety.

[0038] For further information, please see the attached Figure 5 and attached Figure 6 A bidirectional threaded rod 616 is connected to the bearing on the bottom plate 61, and threaded sleeves 617 are threadedly connected on both sides of the bidirectional threaded rod 616. A third motor 618 is also installed on the bottom plate 61, and the output shaft of the third motor 618 is fixedly connected to the end of the bidirectional threaded rod 616. Connecting rods 619 are installed on both sides of the threaded sleeve 617, and a slide groove 620 is provided in the connecting rod 619. A slide rod 621 is slidably connected in the slide groove 620, and a slider 622 is installed at one end of the slide rod 621. The outside of the slider 622 is slidably connected to a slideway 623, and both ends of the slideway 623 are fixedly connected to the support frame 62.

[0039] It should be understood that, by rotating the third motor 618, the bidirectional threaded rod 616 is driven to rotate, and under the action of the threaded connection between the bidirectional threaded rod 616 and the threaded sleeve 617, the connecting rod 619 is driven to move on the base plate 61, and is slidably connected to the slide rod 621 through the slide groove 620, and the slider 622 is driven to move synchronously in the slideway 623, so as to facilitate the adjustment of the grinding position of the second grinding head 66, and through the setting of the slider 622 and the slideway 623, when the second grinding head 66 moves, the angle also changes, so that the second grinding head 66 and the drilling position of the curved glass 7 are always kept in a vertical state, which is convenient for grinding the edge of the drilling hole.

[0040] Furthermore, a connecting frame 624 is provided on the outside of the support frame 62, and the connecting frame 624 is fixedly connected to the slider 622. A third electric push rod 625 is also installed on both sides of the connecting frame 624, and the telescopic end of the third electric push rod 625 is fixedly connected to the support frame 62. In this embodiment, when the third electric push rod 625 performs a telescopic movement, it is convenient to drive the support frame 62 to move synchronously, thereby facilitating the insertion of the second grinding head 66 into the drilling position, thereby facilitating the grinding of the drilled hole.

[0041] It should be noted that, in this embodiment, a fourth electric push rod can be installed on both sides of the base 1, and the telescopic end of the fourth electric push rod is fixedly connected to the bottom plate 61, so as to facilitate the control of the movement of the bottom plate 61 and facilitate the adjustment of the grinding position.

[0042] Working principle: Place the curved glass 7 on the positioning suction cup 54, and clamp and position the curved glass 7 through the positioning suction cup 54, so that the curved glass 7 remains in a fixed state;

[0043] Subsequently, the hydraulic cylinder 31 drives the drilling device 33 to move, and rotates through the first motor 34 so that the drilling head 35 maintains a vertical relationship with the drilling position;

[0044] When working, the drilling device 33 drives the drilling head 35 to rotate, so that the drilling head 35 performs drilling processing on the curved glass 7. While drilling, the supporting suction cup 614 supports the drilling area, thereby preventing the curved glass 7 from being broken when drilling.

[0045] After the drilling is completed, the hydraulic cylinder 31 controls the drilling head 35 to continue to move, so that the first grinding head 37 grinds the edge of the drill hole, so that the burrs and broken surfaces are polished, thereby avoiding scratches on the operator's hands;

[0046] At the same time, the second motor 610 controls the rotation of the rotating table 63 through the pulley transmission mechanism 611, and drives the grinding table 64 to rotate, so that the second grinding head 66 grinds the bottom edge of the drilling position. Therefore, through the setting of the first grinding head 37 and the second grinding head 66, it is convenient to synchronously grind the upper and lower edges of the drilling position. The operation is simple and convenient, which avoids the need for secondary processing of the drilling position and improves work efficiency.
