Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a glass breaking device and glass cutting equipment. Background Technology

[0002] In the scribing and breaking process of substrate glass or carrier glass, the glass is scribed alternately by two sets of cutters on the X and Y axes of the scribing machine to scribing the edges around the glass to mark the required dimensions. After scribing is completed, the glass breaking device breaks off the feed part around the glass along the scribing lines.

[0003] In related technologies, after the glass is conveyed to the breaking station by a conveyor belt, the glass breaking device directly presses down on the feed section and breaks it. During the breaking process, the glass is prone to slight shaking, which causes the glass to fall off at the breaking point, reducing the quality of the glass. In severe cases, cracks may extend from the point of falling off, causing the glass to break or be scrapped. Utility Model Content

[0004] The purpose of this invention is to provide a glass breaking device and a glass cutting equipment to prevent glass from breaking into pieces and cracking during the breaking process, thereby improving the quality of glass products.

[0018] The beneficial effects of this utility model are as follows:

[0019] The glass breaking device proposed in this utility model uses a lifting drive to move a lifting frame vertically, causing the lower pressure component and the breaking assembly to move to the breaking height along with the lifting frame. Simultaneously, a lifting mechanism supports the breaking point of the glass and lifts the glass to the breaking height, while the lower pressure component presses against the main body, causing the glass to be tilted at the breaking height. The breaking assembly breaks the feed portion along the marked line from the main body.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] This embodiment proposes a glass cutting device, which includes a glass scribing device and a glass breaking device. When the glass 10 moves to the scribing station along the conveyor belt (not shown in the figure), the two sets of cutters on the X and Y axes of the glass scribing device alternately scribing lines on the edges around the glass 10 to mark the required dimensions, thereby dividing the glass 10 into a main body 101 and a feed portion 102 (such as a glass breakage portion) located around the main body 101 by the scribing lines at the breaking point. Figure 1 (As shown). Then, the glass 10 moves with the conveyor belt to the breaking station, where the bait section 102 is broken off from the main body 101 along the marking line by the glass breaking device. Since the glass marking device is existing technology, its structure and working process will not be described in detail.

[0030] When the glass 10 is conveyed to the breaking station by the conveyor belt, the glass breaking device directly presses down on the feed section 102 and breaks it. During the breaking process, the glass 10 is prone to slight shaking, which causes the glass 10 to fall off at the breaking point, reducing the quality of the glass 10. In severe cases, cracks may extend from the falling off point, causing the glass 10 to break or be scrapped.

[0031] To solve the above problems, such as Figure 1As shown, this embodiment also proposes a glass breaking device, which includes a breaking mechanism and a lifting mechanism 5. The breaking mechanism includes a lifting drive 1, a lifting frame 2, a pressing member 3, and a breaking assembly 4. The pressing member 3 and the breaking assembly 4 are spaced apart from each other on the lifting frame 2. The lifting drive 1 drives the lifting frame 2 to move up and down in the height direction (the vertical direction in the figure), so that the pressing member 3 and the breaking assembly 4 move with the lifting frame 2 to the breaking height. The lifting mechanism 5 is located below the breaking mechanism and between the pressing member 3 and the breaking assembly 4. The lifting mechanism 5 supports the breaking point of the glass 10 and lifts the glass 10 to the breaking height. The pressing member 3 faces and presses against the main body 101. The glass 10 is inclined at the breaking height, and the bait part 102 is higher than the main body 101. The breaking assembly 4 faces the bait part 102 and is configured to break the bait part 102 from the main body 101 along the marked line. After the glass 10 is conveyed to the breaking station by the conveyor belt, the lifting drive 1 drives the lifting frame 2 to move up and down in the height direction, so that the pressing component 3 and the breaking assembly 4 move with the lifting frame 2 to the breaking height. At the same time, the lifting mechanism 5 supports the breaking point of the glass 10 and lifts the glass 10 to the breaking height, while the pressing component 3 presses against the main body 101, so that the glass 10 is tilted at the breaking height. The breaking assembly 4 breaks the bait part 102 from the main body 101 along the marked line. While the lifting mechanism 5 supports the breaking point of the glass 10, the pressing component 3 presses down on the main body 101 of the glass 10 to press and fix the glass 10, which improves the stability of the glass 10 at the breaking height and prevents the glass 10 from shaking or shifting position during the breaking process. This avoids the glass 10 from falling off pieces and cracking during breaking, thus improving the product quality of the glass 10.

[0032] Specifically, the conveyor belt transports the glass 10 from back to front to the breaking station. The lifting mechanism 5 is located between two adjacent conveyor belts so that it can detach the glass 10 from the conveyor belt and lift it to the breaking height. The pressing member 3 and the breaking assembly 4 are spaced apart on the lifting frame 2 along the front-back direction. The lifting mechanism 5 and the pressing member 3 are staggered along the height direction. The lifting mechanism 5 presses against the lower surface of the glass 10 at the breaking position, and the pressing member 3 presses against the upper surface of the main body 101 of the glass 10. This results in the glass 10 being in an inclined state when it is lifted to the breaking height. The bait part 102 of the glass 10 is higher than the main body 101, increasing the distance between the bait part 102 of the glass 10 and the conveyor belt below. This prevents interference between the breaking mechanism and the conveyor belt below when it presses down to break the bait part 102, thus ensuring the smooth breaking process of the glass 10.

[0033] like Figure 1As shown, the breaking mechanism also includes a fixed frame 6, a lifting drive component 1 mounted on the fixed frame 6, and a lead screw 61 mounted on the fixed frame 6 along the height direction. The lifting drive component 1 is connected to the lead screw 61. The lifting frame 2 is equipped with a slider 21, which is threadedly connected to the lead screw 61. The threaded connection between the lead screw 61 and the slider 21 improves the accuracy of the lifting frame 2's vertical movement, ensuring that the pressing component 3 and the breaking assembly 4 move precisely to the breaking height.

[0034] In this embodiment, the glass-breaking device also includes two gear steering boxes 7, and two lead screws 61 are spaced apart along the front-rear direction. The lifting drive component 1 is a servo motor, which can achieve precise position, speed, and torque control, and maintain high efficiency and low energy consumption over a wide speed range. The lifting drive component 1 is connected to the two gear steering boxes 7 via the same drive shaft, so that the two gear steering boxes 7 are respectively connected to the corresponding lead screws 61. The gear steering boxes 7 change the direction of power through gear meshing, which has the advantages of high efficiency, reliability, and flexibility. In this embodiment, the gear steering boxes 7 are right-angle steering boxes, so that the power transmission direction of the lifting drive component 1 can be changed by 90° through the gear steering boxes 7. The lifting frame 2 is provided with two sliders 21, and the sliders 21 are threadedly connected to the lead screws 61 one-to-one, which further improves the accuracy of the lifting frame 2 in the vertical direction.

[0035] like Figure 1 As shown, the lifting frame 2 has a slot (not shown in the figure) extending along the scribed line, and one end of the pressing component 3 is snapped into the slot. The pressing component 3 can be detachably installed on the lifting frame 2 by snapping, which facilitates the disassembly and replacement of the pressing component 3 and improves the efficiency of disassembly and assembly of the pressing component 3.

[0036] In an optional embodiment, the pressing member 3 is a brush, with the brush handle engaged in a slot, and the brush bristles pressing against the upper surface of the glass 10 at the break height. Because the brush bristles are relatively soft, they can elastically press against the upper surface of the glass 10, preventing the pressing member 3 from causing scratches or other damage to the glass 10, thus protecting the surface quality of the glass 10. It should be noted that the pressing member 3 extends along the scratch line at the break point, preventing dust from spreading over a large area to the upper surface of the main body 101, reducing the area of ​​dust adhering to the upper surface of the main body 101, and facilitating rapid dust removal from the glass 10. Furthermore, a brush with a high bristle density is preferred to ensure the brush's pressing force against the glass 10, improve the stability of the glass 10 at the break height, and simultaneously enhance the brush's dust isolation and blocking effect.

[0037] In an optional embodiment, the breaking assembly 4 includes a breaking drive 41 and a pressure bar 42. The breaking drive 41 is disposed on the lifting frame 2 and is tractively connected to the pressure bar 42 to drive the pressure bar 42 to descend along the height direction, thereby breaking the bait part 102 from the main body 101 along the marked line. When the lifting frame 2 rises and falls to the breaking height, the glass 10 is tilted under the misaligned pressing action of the lowering member 3 and the lifting mechanism 5. The breaking drive 41 drives the pressure bar 42 to extend downward along the height direction and press down on the bait part 102, thereby breaking the bait part 102 from the main body 101 along the marked line. In this embodiment, the breaking drive 41 is a cylinder. Cylinders have a simple structure, high reliability, and are easy to install and maintain.

[0038] In an optional embodiment, the lifting mechanism 5 includes a lifting drive 51 and a lifting plate 52. The lifting drive 51 is tractively connected to the lifting plate 52 to drive the lifting plate 52 to move up and down in the height direction. The lifting plate 52 extends along the marked line and can abut against the break point of the glass 10. The lifting plate 52 extends along the marked line at the break point. When the glass 10 moves to the break point with the conveyor belt, the lifting drive 51 drives the lifting plate 52 to rise and protrude between the two conveyor belts, so that the lifting plate 52 supports the break point of the glass 10 and lifts the glass 10 away from the conveyor belt to the break height. In this embodiment, the lifting drive 51 is a cylinder. Cylinders have a simple structure, high reliability, and are easy to install and maintain.

[0039] like Figure 1 As shown, the breaking mechanism also includes a dust collection mechanism 8, which is mounted on the lifting frame 2 and located on one side of the feed section 102. The dust collection port of the dust collection mechanism 8 faces the breaking point of the glass 10. By setting up the dust collection mechanism 8, the dust generated when the glass 10 is broken is removed, thus achieving dust removal during the breaking of the glass 10, improving the product quality after the glass 10 is broken and the cleanliness of the glass 10 production line, thereby improving the product yield of the glass 10.

[0040] In an optional embodiment, the dust collection mechanism 8 includes an exhaust fan and multiple suction pipes. The exhaust fan is connected to the multiple suction pipes, and the nozzles of the suction pipes face the broken part of the glass 10. The multiple suction pipes are installed at intervals along the marked direction on the lifting frame 2. When the glass 10 breaks, the exhaust fan is turned on, and the dust at the broken part of the glass 10 is sucked away by the multiple suction pipes and collected in the dust collection box.

[0041] like Figure 1 As shown, the breaking mechanism also includes an air blowing mechanism 9, which is mounted on the lifting frame 2 and located on one side of the main body 101. The air blowing port of the air blowing mechanism 9 faces the breaking point of the glass 10. By providing an air blowing mechanism on one side of the main body 101 of the glass 10, the dust generated when the glass 10 is broken is blown towards the bait section 102, making it easier for the dust suction mechanism 8 to quickly remove the dust, preventing dust from adhering to the surface of the glass 10, and improving the dust removal effect and efficiency.

[0042] In an optional embodiment, the breaking mechanism further includes an image acquisition module (not shown in the figure). The image acquisition module is mounted on the lifting frame 2 and is used to acquire images of the broken point of the glass 10. The image acquisition module can be a CCD camera. By acquiring images of the broken point of the glass 10, it is possible to determine whether there are any chips or cracks after the glass 10 is broken, thereby achieving quality inspection of the broken glass 10 and improving the product quality of the glass 10. Acquiring images with a CCD camera and detecting the quality of the glass 10 through images is existing technology, and the working process of the CCD camera will not be described in detail.

[0043] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
