[0025] For example, Figure 1The utility model provides a glass cold crack equipment, including workstation 1, be provided with glass transportation subassembly 3 on workstation 1, glass transportation subassembly 3 includes two opposite clamping sides, is used for clamping the both sides of glass, workstation 1 still is provided with first cooling subassembly 11, first cooling subassembly 11 is located the middle part of two clamping sides, its working head can be close to glass, the glass cold crack equipment still includes the rack 2 of being arranged across workstation 1 both sides, the middle part of rack 2 is provided with second cooling subassembly 21 towards glass transportation subassembly 3, second cooling subassembly 21 is opposite with first cooling subassembly, first cooling subassembly 11 and second cooling subassembly 21 work together to crack glass.

[0026] In the embodiment of the application, the glass cold crack equipment includes a workstation 1, which is a basic support structure of the glass cold crack equipment and is used for mounting and fixing other components. The glass transportation subassembly 3 is mounted on the workstation 1, and the glass transportation subassembly 3 has two opposite clamping sides for clamping and transporting the glass. The clamping sides can tightly clamp the two sides of the glass, so as to stably transport the glass to the workstation 1. The middle part of the two clamping sides is provided with a first cooling subassembly 11. The workstation 1 is further provided with a rack 2 across the two sides of the workstation 1. The middle part of the rack 2 is provided with a second cooling subassembly 21, which is opposite to the first cooling subassembly 11. When the glass is transported to the workstation 1, the first cooling subassembly 11 and the second cooling subassembly 12 work simultaneously to generate a stress difference in the inner and outer contours of the glass. With the decrease of temperature and the accumulation of stress, the glass will eventually crack at a predetermined position. The glass transported to the workstation 1 from the glass transportation subassembly 3 has been subjected to laser cutting and heating treatment.

[0027] In the embodiment of the application, the first cooling subassembly 11 and the second cooling subassembly 21 are provided with pipelines for feeding low-temperature cooling medium into the working surfaces of the first cooling subassembly 11 and the second cooling subassembly 21, so as to directly and effectively cool the inner and outer contours of the cutting track of the glass. The type and temperature of the low-temperature cooling medium can be adjusted according to different glass materials and cutting requirements.

[0028] As Figure 1As shown, in some embodiments, the first driving member 22 is mounted on the rack 2 and connected with the second cooling assembly 21. The first driving member 22 is used to drive the second cooling assembly 21 to move in the vertical direction. When the second cooling assembly 21 moves downward, the outer glass surface of the glass to be processed can be accessed for cooling operation. The second driving member 12 is arranged on the workbench 1 and connected with the first cooling assembly 11. The second driving member 12 is used to drive the first cooling assembly 11 to approach or move away from the inner glass surface of the glass to be processed. By adjusting the position of the first cooling assembly 11 through the second driving member 12, the distance between the first cooling assembly 11 and the inner glass surface can be controlled. Through the first driving member 22 and the second driving member 12, the first cooling assembly 11 and the second cooling assembly 21 can always be kept in the best working position to cope with different thicknesses of glass and various crack processing requirements, thereby improving the quality and efficiency of crack processing. At the same time, through the distance between the working surface of the first cooling assembly 11 and the second cooling assembly 21 and the glass surface, different processes in the glass cold cracking process can be carried out.

[0029] As shown in the drawings, Figure 2 In some embodiments, the rack is also provided with a support 23, which is provided with a transverse sliding rail 231, a longitudinal sliding rail 232 and a sliding member 233. The sliding member 233 is arranged at the intersection of the transverse sliding rail 231 and the longitudinal sliding rail 232 and the second cooling assembly 21. One end of the second cooling assembly 21 is movably connected with the longitudinal guide rail, and the second cooling assembly 21 can move up and down along the longitudinal guide rail 232. Due to the combination of the sliding member 233, the transverse sliding rail 231 and the longitudinal sliding rail 232, the second cooling assembly 21 can move freely in a two-dimensional plane. Since the sliding member 233 can move freely in a two-dimensional plane, the second cooling assembly 21 can be positioned at any position of the outer glass surface of the glass to be processed. The position of the second cooling assembly 21 can be adjusted according to the position of the cutting crack on the glass to be processed, so as to ensure that the cutting trajectory of the glass towards the second cooling assembly 21 can be cooled.

[0030] In some embodiments, the second cooling assembly 21 is provided with a gas passage connected with a high-pressure gas source, and the blowing direction of the gas passage is directly towards the outer glass surface of the glass to be processed. The waste generated during the cooling process is removed by blowing high-pressure gas. At the same time, a waste collection area is arranged below the first cooling assembly 11 for collecting waste or other impurities blown off or naturally fallen from the glass. By collecting the waste and debris in time, it can prevent the waste and debris from entering the moving parts of the equipment or causing blockage, thereby improving the reliability and stability of the equipment.

[0031] As shown in the drawings, Figure 1As shown, in some embodiments, the glass conveying assembly 3 comprises a conveying belt 31, a transmission motor 32 and a third driving assembly 33. The transmission motor 32 is in transmission connection with the conveying belt 31 and is responsible for driving the glass to be processed on the conveying belt 31 to move in the horizontal direction to realize the continuous conveying of the glass. The third driving assembly 33 is used to drive the glass conveying assembly 3 to move up and down in the vertical direction to meet different processing heights and adjust the height between the glass to be processed and the workbench 1. Through the cooperation between the conveying belt 31, the transmission motor 32 and the third driving assembly 33, the glass conveying assembly 3 can stably and accurately convey the glass to be processed from the input end to the workbench 1, while reducing the dependence on manual operation and improving the processing efficiency and the automation degree of the glass cold cracking equipment.

[0032] As shown, the workbench 1 is provided with two support rails 13 for supporting the glass to be processed conveyed by the glass conveying assembly 3. In addition, the workbench 1 is also provided with a guide rail 14 cooperating with the support rails 13 and an adjusting hand wheel 15. The adjusting hand wheel 15 can adjust the distance between the two support rails 13 by driving the rotation of the guide rail 14. By driving the guide rail 14 to rotate through the adjusting hand wheel 15, the distance between the two support rails 13 can be easily adjusted to adapt to glasses of different widths or sizes, so that the glass cold cracking equipment can process more types of glass, thereby improving the utilization rate of the equipment and the processing range of the glass.

[0033] Further, the support rails 13 are also provided with photoelectric sensors on the contact surface with the glass to be processed. The photoelectric sensors are used to determine the position information of the glass to be processed to ensure that the glass to be processed is stably dropped onto the support rails 13 from the conveying belt 31. The real-time position information provided by the photoelectric sensors can be used to automatically adjust the operating state of the equipment to realize the automatic operation of the equipment.

[0034] As shown, Figure 1 and Figure 2 As shown, in another embodiment, the glass cold cracking equipment is also provided with an electrical control assembly which is electrically connected with the workbench 1, the rack 2 and the glass conveying assembly 3 and is responsible for the electrical control and signal transmission of the entire equipment. Through the preset program, the electrical control assembly can control the workbench 1, the glass conveying assembly 3, the first cooling assembly 11 and the second cooling assembly 21 to work, thereby realizing the automation and integration of the entire processing process. The electrical control assembly can monitor the working state and performance index of the equipment in real time. Once an abnormal situation or failure is found, an alarm is immediately sent out and corresponding protection measures are taken to ensure the safe operation of the equipment. The automatic control helps to reduce the dependence on manual operation, improve the processing efficiency and precision.

[0035] As shown, Figure 1As shown, in some embodiments, a glass positioning assembly 4 is also provided, which is composed of several blocking air cylinders, one end of which is fixed to the frame and the other end of which is downwardly inserted into the glass conveying assembly. Before the glass to be processed is conveyed to the workbench 1, the blocking air cylinders are extended and contact the glass to be processed on the conveying belt 31, so as to determine the position of the glass on the conveying belt 31 for the next work process. The blocking air cylinders work according to the instructions of the electrical control assembly, so that the operator does not need to manually adjust the position of the glass, thereby simplifying the operation process, improving the work efficiency, and reducing the quality problems caused by human operation errors.

[0036] In the above embodiment of the glass cold cracking device, the work process during operation is as follows:

[0037] In the initial state, under the drive of the transmission motor 32, the glass to be processed moves horizontally on the conveying belt 31 of the glass conveying assembly 3, the blocking air cylinders in the glass positioning assembly 4 are in the extended state, and the glass cold cracking device is in the standby state. When the glass to be processed approaches the blocking air cylinders, the transmission motor 32 slows down until it completely stops when contacting the blocking air cylinders, and then the third drive assembly 33 drives the conveying belt 31 to descend according to the preset height, and the photoelectric sensor ensures that the glass is smoothly transferred to the support rail on the workbench 1. Then, the first drive member 22 is started to drive the bracket 23 to move in the three-dimensional space in the frame 2, preparing for the cooling operation, and the second drive member 12 drives the first cooling assembly 11 to approach the inner glass surface of the glass to be processed, ensuring that both the inner and outer surfaces can be uniformly cooled. Among them, the low-temperature cooling medium pipelines in the first cooling assembly 11 and the second cooling assembly 21 start to pass the low-temperature cooling medium to cool the inner contour of the cutting track of the glass. When the glass reaches the preset cooling effect, the first cooling assembly 11 and the second cooling assembly 21 stop working, the first cooling assembly 11 descends, and the gas passage on the second cooling assembly 21 is connected to the high-pressure gas source, and the blowing direction is towards the outer glass surface of the glass to be processed, so that the waste generated during the cooling process can be smoothly removed in the first cooling assembly 11. After a certain period of time, the second cooling assembly 21 is lifted, the glass conveying assembly 3 is lifted, and the main product is sent to the next process by the transmission motor 32, and the glass cold cracking device enters the standby state, waiting for the next operation.

[0038] In summary, the application provides a glass cold cracking device, the first cooling assembly 11 and the second cooling assembly 21 can cool from the inner and outer surfaces of the glass respectively, thereby realizing local multi-region cooling and improving the brittle material cracking yield; the distance between the two support rails 13 can be conveniently adjusted by adjusting the hand wheel 15 to drive the guide rail 14 to rotate, so as to adapt to glass of different widths; the low-temperature cooling medium circulates in the second cooling assembly 21 and the first cooling assembly 11 through the pipeline, thereby ensuring the continuity and stability of the cooling effect; the electrical control assembly is electrically connected with the workbench 1 and the rack 2, the position information of the glass is monitored in real time through the photoelectric sensor, feedback is provided for the electrical control assembly, the operation of the device can be automatically controlled through the preset program, and intelligent adjustment and control of the device can be realized.
