Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, and specifically relates to an automatic glass breaking device. Background Technology

[0002] The glass slitting process mainly includes the following steps: the feeding process, in which a robotic arm with a suction cup is used to place the glass sheet onto a conveyor for transport; the cutting process, in which the glass sheet is cut by a cutting wheel, forming multiple equidistant slits on the surface of the glass sheet; and the breaking process, in which the glass sheet is broken apart according to the slits.

[0003] Traditional glass breaking processes mostly rely on manual labor, which is not only labor-intensive and inefficient but also results in a high defect rate and increased costs. Existing technologies employ glass breaking devices, primarily using hydraulic pushers to directly apply pressure to the glass at the notch. This process generates significant impact on the glass, potentially causing it to break directly. Other glass breaking devices utilize cams or pressure rods to press down on the glass to achieve the same effect. However, when these devices press directly onto the glass, the contact area between them and the glass is small, easily leading to uneven stress on the glass surface and causing localized excessive stress that results in breakage.

[0004] Therefore, there is an urgent need for an automatic glass breaking device to solve the above problems. Utility Model Content

[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides an automatic glass breaking device, comprising a first conveyor, a support platform, a support plate, a second conveyor, a pressing mechanism, and a breaking mechanism. The first conveyor, support platform, support plate, and second conveyor are arranged sequentially along the conveying direction. The support platform is located at the discharge end of the first conveyor, and the height of the support platform is level with the height of the top surface of the first conveyor. One end of the support plate is hinged to the side of the support platform, and the support plate is inclined downward along the conveying direction. The other end of the support plate corresponds to the feed end of the second conveyor, and the other end of the support plate is higher than the top surface of the second conveyor.

[0006] The pressing mechanism is located above the support platform and is used to press the upper surface of the glass plate on the support platform.

[0007] The glass breaking mechanism is located above the support plate. The glass breaking mechanism includes a drive device and a pressure plate. The drive device can drive the pressure plate to press down on the glass plate on the support plate so that the glass plate breaks along the slit.

[0008] Optionally, a first support base is provided below the first conveyor, the support platform, and the support plate, and a second support base is provided below the second conveyor.

[0009] Optionally, a support frame is provided on the first support base, the support frame including a top plate and a vertical rod fixedly connected between the top plate and the first support base.

[0010] Optionally, the tablet pressing mechanism includes a lifting cylinder and a pressure roller assembly. The cylinder seat of the lifting cylinder is fixed to the bottom surface of the top plate. The pressure roller assembly includes several parallel pressure rollers and a mounting frame disposed outside the several pressure rollers. The mounting frame is fixedly connected to the piston rod of the lifting cylinder. The pressure roller assembly is vertically opposite to the support platform and the idler roller at the tail end of the first conveyor.

[0011] Optionally, the drive device uses hydraulic cylinders, and there are two hydraulic cylinders. The cylinder seats of the two hydraulic cylinders are fixed on the bottom surface of the top plate, and the piston rods of the two hydraulic cylinders are respectively fixedly connected to connecting rods. The pressure plate is located between the two connecting rods, and the top surface of the pressure plate is hinged to the bottom end of the two connecting rods.

[0012] Optionally, mounting plates are fixed to the front and rear sides of each connecting rod, and springs are connected between each mounting plate and the pressure plate.

[0013] Specifically, this design allows the pressure plate to return to its horizontal position after the glass is broken, facilitating subsequent operations and aiding in continuous glass breaking processing.

[0014] Optionally, the bottom surface of the pressure plate is provided with a cushioning pad, and the cushioning pad is made of rubber or silicone.

[0015] Specifically, the buffer pad can provide a certain cushioning effect when the pressure plate presses down on the glass plate, protecting the surface of the glass plate and reducing damage.

[0016] Optionally, a flaw detection photoelectric sensor is provided on the top plate, and the flaw detection photoelectric sensor is located directly above the connection between the support platform and the support plate.

[0017] Specifically, the flaw detection photoelectric sensor can be connected to a PLC control system that controls the actions of the two conveyors, electric push rods, lifting cylinders, and hydraulic cylinders. The photoelectric sensor detects changes in the light intensity of the glass plate, converts these changes into electrical signal changes, and sends the signals to the PLC controller, thereby sensing the cut in the glass plate. When the cut in the glass plate is detected, it indicates that the portion of the glass plate to be broken off is ready above the support plate. At this time, the PLC controller can control the first conveyor to pause its conveying and simultaneously control the hydraulic cylinder to start working, causing the pressure plate to complete the breaking operation, thus enabling the automatic glass breaking device to complete the automated breaking process.

[0018] Optionally, an electric push rod is provided between the support plate and the support platform. One end of the electric push rod is hinged to the side of the support platform, and the free end of the electric push rod is hinged to the bottom surface of the support plate.

[0019] Specifically, the tilt angle of the support plate can be adjusted by an electric push rod, which makes it easy to adjust the angle according to the size of the glass plate to be processed, and it can also be flexibly connected to the next station, making it more flexible to use.

[0020] This invention also includes other components that enable the automatic glass breaking device to function properly, all of which are conventional technologies in the field. Furthermore, any devices or components not specified in this invention employ conventional technologies in the field, such as a first conveyor, a second conveyor, an electric push rod, a lifting cylinder, a hydraulic cylinder, and a flaw detection photoelectric sensor.

[0021] The working principle of this utility model is as follows: During use, the glass plate moves under the conveying action of the first conveyor. After the flaw detection photoelectric sensor detects that the end of the glass plate to be broken off has moved above the support plate and is ready, the first conveyor stops and the breaking operation begins. The lifting cylinder starts and stretches the piston rod, lowers the pressure roller group and presses it on the upper surface of the glass plate to prevent the glass plate from tilting during the breaking process. The hydraulic cylinder starts and stretches the piston rod, lowers the pressure plate and presses the glass plate down to break the glass plate along the cut. Because the pressure plate has a large area, it can convert local single-point force into multi-point force, so that the glass plate is subjected to uniform force and avoids breakage. After the breaking is completed, both the lifting cylinder and the hydraulic cylinder stretch the piston rod. The pressure plate returns to its original position under the rebound action of the spring. The broken glass piece slides down the inclined support plate onto the second conveyor and is then transported by the second conveyor to the next process. After that, the first conveyor starts and continues to transport the remaining glass plate to start the next round of breaking operation.

[0022] The beneficial effects of this utility model are that, through the first conveyor, support platform, support plate, second conveyor, pressing mechanism and breaking mechanism, glass plates can be broken into pieces, which solves the problems of low efficiency and high defect rate of traditional manual breaking. In addition, the breaking mechanism uses a pressure plate instead of the cam and pressure rod in the existing device, which increases the contact area so that the glass plate is subjected to force at multiple points, the force is more uniform, and the breakage is avoided, thus improving product quality.

The support platform 2 is located at the discharge end of the first conveyor 1, and the height of the support platform 2 is level with the height of the top surface of the first conveyor 1. One end of the support plate 3 is hinged to the side of the support platform 2, and the support plate 3 is inclined downward along the conveying direction. The other end of the support plate 3 corresponds to the feed end of the second conveyor 4, and the other end of the support plate 3 is higher than the top surface of the second conveyor 4. A first support seat 7 is provided below the first conveyor 1, support platform 2, and support plate 3, and a second support seat 8 is provided below the second conveyor 4. A support frame is provided on the first support seat 7, and the support frame includes a top plate 9 and a vertical rod 10 fixedly connected between the top plate 9 and the first support seat 7.

[0033] The tablet pressing mechanism 5 is located above the support platform 2. The tablet pressing mechanism 5 includes a lifting cylinder 11 and a pressure roller assembly 12. The cylinder seat of the lifting cylinder 11 is fixed to the bottom surface of the top plate 9. The pressure roller assembly 12 includes several parallel pressure rollers and a mounting frame disposed outside the several pressure rollers. The mounting frame is fixedly connected to the piston rod of the lifting cylinder 11. The pressure roller assembly 12 is vertically opposite to the support platform 2 and the idler roller at the tail end of the first conveyor 1.

[0034] The glass breaking mechanism 6 is located above the support plate 3. The glass breaking mechanism 6 includes two hydraulic cylinders 13 and a pressure plate 14. The cylinder seats of the two hydraulic cylinders 13 are fixed to the bottom surface of the top plate 9, and the piston rods of the two hydraulic cylinders 13 are respectively fixedly connected to connecting rods 15. The pressure plate 14 is located between the two connecting rods 15, and the top surface of the pressure plate 14 is hinged to the bottom end of the two connecting rods 15. Mounting plates 16 are fixed to the front and rear sides of each connecting rod 15, and springs 17 are connected between each mounting plate 16 and the pressure plate 14. This design can make the pressure plate 14 return to its horizontal original position after breaking, which facilitates subsequent operations and helps the continuous breaking of the glass plate 21. A rubber buffer pad 18 is provided on the bottom surface of the pressure plate 14. The rubber buffer pad 18 can play a certain buffering role when the pressure plate 14 presses down on the glass plate 21, protecting the surface of the glass plate 21 and reducing damage.

[0035] In addition, a flaw detection photoelectric sensor 19 is installed on the top plate 9, and the flaw detection photoelectric sensor 19 is located directly above the connection between the support platform 2 and the support plate 3. The flaw detection photoelectric sensor 19 is used to detect the positioning of the glass plate 21. An electric push rod 20 is installed between the support plate 3 and the support platform 2.

[0036] The working principle of this utility model is as follows: During use, the glass plate 21 moves under the conveying action of the first conveyor 1.

After the glass is broken, the lifting cylinder 11 and the hydraulic cylinder 13 both stretch the piston rod. The pressure plate 14 is reset under the rebound action of the spring 17. The broken glass pieces slide down the inclined support plate 3 onto the second conveyor 4 and are then transported to the next process by the second conveyor 4. After that, the first conveyor 1 is started to continue transporting the remaining glass plate 21 and start the next round of glass breaking operation.
