Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass processing equipment technology, specifically to a glass hole chamfering device. Background Technology
[0002] In glass production and processing, it is often necessary to chamfer the glass holes.
[0003] Currently, in the chamfering process for glass holes on glass plates, for small-scale, piecemeal processing of glass plates in a workshop, a chamfering cone is mounted on a motor shaft, and the glass holes are manually chamfered directly using the chamfering cone. For continuous processing of large quantities of glass plates, a CNC motor mounted on a chamfering cone is used for precise positioning and processing. However, in both of these methods, the chamfering cone inevitably experiences severe vibration during processing. This hard contact between the chamfering cone and the glass plate not only easily causes significant chipping at the edges of the glass holes, increasing the risk of glass breakage, but also severely reduces the quality of the chamfering, resulting in low precision. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a glass hole chamfering device. This device can automatically chamfer the glass holes on a glass plate, avoid the risk of chipping at the edges of the glass holes, reduce the risk of glass breakage, and improve the chamfering quality. The technical solution adopted is as follows:
[0005] A glass beveling device, characterized in that it includes a base, a lifting frame, a lifting mechanism for driving the lifting frame to lift, a rotating beveling component, a rotating mechanism for driving the rotating beveling component to rotate, a receiving tray, a water spraying mechanism, and a controller. The lifting mechanism is mounted on the base, the rotating mechanism is mounted on the lifting frame, the rotating beveling component includes a beveling grinding wheel and an elastic buffer mechanism, the beveling grinding wheel is mounted on the power output end of the rotating mechanism through the elastic buffer mechanism; the receiving tray is located directly below the beveling grinding wheel; the water outlet of the water spraying mechanism is located on one side of the beveling grinding wheel and faces downwards from the beveling grinding wheel; the lifting mechanism, the rotating mechanism, the water spraying mechanism, and the corresponding output ends of the controller are electrically connected.
[0006] During operation, under the control of the controller, a glass plate with perforations is conveyed by a clamping and conveying mechanism to the processing station of the glass perforation chamfering device. At this time, the glass plate is placed horizontally, with the perforations directly below the chamfering grinding wheel. Subsequently, the chamfering grinding wheel of the rotating chamfering component is continuously rotated by a rotating mechanism, and the lifting frame and its rotating mechanism and rotating chamfering component are lowered by a lifting mechanism until the chamfering grinding wheel of the rotating chamfering component contacts the edge of the perforation on the glass plate, automatically completing the chamfering process of the glass perforation. At the same time, a water spraying mechanism sprays water onto the perforations on the glass plate through its outlet to achieve a cooling effect. A receiving tray is used to collect the slag and wastewater generated during the chamfering process to prevent pollution of the workshop environment. When the chamfering grinding wheel vibrates or jumps during the chamfering process, the elastic buffer mechanism can buffer the chamfering grinding wheel, which can prevent the risk of breakage at the edge of the glass perforation, reduce the risk of glass breakage, and improve the chamfering quality and ensure the accuracy of the chamfering.
[0007] As a preferred embodiment of this utility model, the elastic buffer mechanism includes an upper connecting shaft, a lower connecting shaft, a guide seat, a slider, and a spring. The upper connecting shaft is arranged in the vertical direction and connected to the power output end of the rotating mechanism. The lower connecting shaft is arranged below the upper connecting shaft and coincides with the axis of the upper connecting shaft. The upper part of the guide seat is installed at the lower end of the upper connecting shaft. The lower part of the guide seat is provided with a guide hole running vertically. A lower limit ring is provided on the inner wall of the lower end of the guide hole. The slider is installed at the upper end of the lower connecting shaft and can slide up and down along the guide hole. An upper limit ring is provided on the slider to cooperate with the lower limit ring. The spring is arranged in the guide hole, and the upper and lower ends of the spring are in close contact or connected to the guide seat and the slider, respectively. The chamfering grinding wheel is fixedly installed at the lower end of the lower connecting shaft. During operation, the upper connecting shaft of the rotating chamfering component is driven to rotate by the rotating mechanism, and then the lower connecting shaft drives the chamfering grinding wheel to rotate continuously. When the chamfering grinding wheel vibrates or jumps during the chamfering process, the slider will slide up or down along the guide hole, and the spring will stretch and deform accordingly, which can buffer the chamfering grinding wheel.
[0008] The aforementioned elastic buffer mechanism can also employ gas springs or spring sheets, etc.
[0009] As a preferred embodiment of this utility model, the lifting mechanism includes a vertical guide rail, a lifting screw, a lifting slider, and a lifting motor. The vertical guide rail is mounted on the base, and the lifting screw is rotatably mounted on the base and parallel to the vertical guide rail. The lifting motor is mounted on the base, and its output shaft is connected to the lifting screw. The lifting slider is mounted on the vertical guide rail and slides along it. The lifting slider has a threaded hole that engages with the lifting screw, and the lifting screw is positioned within this hole. The lifting frame is mounted on the lifting slider. The lifting motor is electrically connected to the corresponding output terminal of the controller. During operation, the lifting motor drives the lifting screw to rotate forward or backward. Utilizing the engagement between the threaded hole on the lifting slider and the lifting screw, the lifting slider is raised or lowered a certain height along the vertical guide rail, thereby driving the lifting frame to move upward or downward.
[0010] As a further preferred embodiment of this utility model, the glass hole chamfering device further includes a proximity switch and a sensing plate. The proximity switch is mounted on the base and located on one side of the lower part of the vertical guide rail. The sensing plate is mounted on the lifting frame and cooperates with the proximity switch. The proximity switch is electrically connected to the corresponding input terminal of the controller. When the sensing plate descends with the lifting frame to the position corresponding to the proximity switch, the proximity switch is triggered, and the controller controls the lifting motor to stop running, preventing the chamfering grinding wheel from continuing to move downward, which helps to improve the accuracy of chamfering.
[0011] In a preferred embodiment of this invention, the rotating mechanism includes a rotary motor and a reducer. The rotary motor is mounted on the lifting frame, and its output shaft is connected to the upper end of the upper connecting shaft via the reducer. The rotary motor is electrically connected to the corresponding output terminal of the controller. During operation, the rotary motor drives the upper connecting shaft to rotate via the reducer, which in turn drives the chamfering grinding wheel to rotate continuously via the lower connecting shaft.
[0012] As a preferred embodiment of this utility model, the water spraying mechanism includes a water storage container, a water inlet pipe, a water pump, a water spray pipe, and a relay for controlling the start and stop of the water pump. The water pump is mounted on the base, and its inlet is connected to the water storage container via the water inlet pipe. The water spray pipe is mounted on the lifting frame, with its first end opening connected to the water outlet of the water pump, and its second end opening forming the water outlet of the water spraying mechanism. The relay is electrically connected to the corresponding output terminal of the controller. When water spraying is required, the controller starts the water pump via the relay. Water from the water storage container is drawn by the water pump and sequentially passes through the water inlet pipe and the water pump into the water spray pipe, finally being sprayed from the second end opening of the water spray pipe towards the glass holes on the glass plate for cooling. Subsequently, the controller shuts off the water pump via the relay, pausing the water spraying.
[0013] Compared with the prior art, this utility model has the following advantages:
[0014] This glass hole chamfering device can automatically chamfer the glass holes on the glass plate. During the chamfering process, an elastic buffer mechanism is used to buffer the vibration or jumping of the chamfering grinding wheel, so as to avoid the risk of the glass hole edge breaking, reduce the risk of glass breakage, improve the chamfering quality, and ensure the accuracy of the chamfering.

Utilizing the meshing relationship between the screw hole on the lifting slider 33 and the lifting screw 32, the lifting slider 33 is driven to rise or fall a certain height along the vertical guide rail 31, thereby driving the lifting frame 2 to move upward or downward.
[0020] In this embodiment, the glass hole chamfering device further includes a proximity switch 9 and a sensing element 10.

The proximity switch 9 is electrically connected to the corresponding input terminal of the controller 8. When the sensing element 10 descends with the lifting frame 2 to the position corresponding to the proximity switch 9, the proximity switch 9 is triggered, and the controller 8 controls the lifting motor 34 to stop running, so that the lifting frame 2 stops moving downward, which helps to improve the accuracy of chamfering.
[0021] In this embodiment, the elastic buffer mechanism 42 includes an upper connecting shaft 421, a lower connecting shaft 422, a guide seat 423, a slider 424, and a spring 425. The upper connecting shaft 421 is arranged in the vertical direction and connected to the power output end of the rotating mechanism 5. The lower connecting shaft 422 is arranged below the upper connecting shaft 421 and coincides with the axis of the upper connecting shaft 421.

The slider 424 is provided with an upper limit ring 4241 that cooperates with the lower limit ring 4231. The spring 425 is set in the guide hole 4230. The upper end and the lower end of the spring 425 are in close contact or connected with the guide seat 423 and the slider 424 respectively. The chamfering grinding wheel 41 is fixedly installed at the lower end of the lower connecting shaft 422. The rotating mechanism 5 includes a rotating motor 51 and a reducer 52.

During operation, the upper connecting shaft 421 of the rotating chamfering component 4 is driven to rotate by the rotating mechanism 5, and then the lower connecting shaft 422 drives the chamfering grinding wheel 41 to rotate continuously. When the chamfering grinding wheel 41 vibrates or jumps during the chamfering process, the slider 424 will slide up or down along the guide hole 4230, and the spring 425 will undergo corresponding extension and contraction deformation, which can buffer the chamfering grinding wheel 41.
[0022] In this embodiment, the water spraying mechanism 7 includes a water storage container (not shown in the figure), a water pump 71, a water inlet pipe 72, a water spraying pipe 73, and a relay 74 for controlling the start and stop of the water pump 71. The water pump 71 is mounted on the lifting frame 2, and the water inlet of the water pump 71 is connected to the water storage container through the water inlet pipe 72. The water spraying pipe 73 is mounted on the lifting frame 2, and the first end opening of the water spraying pipe 73 is connected to the water outlet of the water pump 71. The second end opening of the water spraying pipe 73 forms the water outlet 701 of the water spraying mechanism 7. The relay 74 is electrically connected to the corresponding output terminal of the controller 8. When the water spraying mechanism 7 needs to spray water, the water pump 71 is started by the relay 74. The water in the water storage container is drawn by the water pump 71 and passes through the water inlet pipe 72 and the water pump 71 into the water spray pipe 73. Then, it is sprayed out from the second end opening of the water spray pipe 73 into the glass hole on the glass plate to cool it down. Subsequently, the controller 8 turns off the water pump 71 by the relay 74 to stop the water spraying.
[0023] The working principle of this glass hole chamfering device is briefly described below:
[0024] During operation, under the control of controller 8, the glass plate with the glass hole is transported to the processing station of the glass hole chamfering device by a clamping and conveying mechanism. At this time, the glass plate is placed horizontally, and the glass hole on the glass plate is directly below the chamfering grinding wheel 41. Subsequently, the chamfering grinding wheel 41 of the rotating chamfering component 4 is driven to rotate continuously by the rotating mechanism 5, and the lifting mechanism 3 drives the lifting frame 2 and the rotating mechanism 5 and the rotating chamfering component 4 on it to descend until the chamfering grinding wheel 41 of the rotating chamfering component 4 contacts the edge of the glass hole on the glass plate, automatically completing the chamfering treatment of the glass hole. At the same time, the water spraying mechanism 7 sprays water onto the glass hole on the glass plate through its water outlet 701 to achieve a cooling effect. The receiving tray is used to collect the slag and wastewater generated during the chamfering process to avoid polluting the workshop environment. When the chamfering grinding wheel 41 vibrates or jumps during the chamfering process, the elastic buffer mechanism 42 can buffer the chamfering grinding wheel 41 (the guide block 4221 will slide up or down along the sliding channel 4210, and the spring 423 will expand and contract accordingly), which can avoid the risk of glass hole edge breakage, reduce the risk of glass breakage, improve the chamfering quality, and ensure the accuracy of chamfering.
