Technical Field

[0001] The utility model relates to the technical field of glass processing, and particularly relates to a glass cracking device and a glass punching device. Background Technique

[0002] Glass cutting technology has important applications in modern industry, especially in the processing of glass products such as stove glass, mobile phone screens, optical elements, etc.

[0003] In the related art, a metal heat conduction seat is generally used to quickly heat the area outside the closed path, so that a temperature difference is generated between the heated area and the unheated area of the glass, and then the glass in the closed path is separated from the substrate by using the thermal expansion and contraction effect.

[0004] However, the existing metal heat conduction seat technology has obvious defects. Since the metal heat conduction seat must be specially made according to the position, size, shape and quantity of the opening, when any one of these parameters changes, it is necessary to remanufacture the metal heat conduction seat, which not only increases the production cost, but also reduces the production flexibility and efficiency. Summary of the Utility Model

[0005] The main purpose of the utility model is to propose a glass cracking device, aiming to solve the problem of high cost caused by the need to specially manufacture the metal heat conduction seat according to the position, size, shape and quantity of the opening.

[0006] To achieve the above object, the utility model proposes a glass cracking device, which includes:

[0007] A heating device for generating heat;

The design of the first through hole on the first heat conducting member enables it to be flexibly adjusted according to the specific shape and size of the hole in the glass. When the position, size, shape, and quantity of the holes in the glass change, only the corresponding first heat conducting member needs to be replaced, without the need to remanufacture the entire heating device, greatly reducing the replacement cost and time, and improving the production flexibility and efficiency.

[0034] Next, the solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0035] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If this specific posture changes, the directional indication will also change accordingly.

[0036] It should also be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0037] In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0038] Setting through holes with a preset shape directly on the heating device has a high cost. The main reasons are high customization production requirements, complex manufacturing processes, high costs for mold making and replacement, significant impacts on heating efficiency and uniformity, and high maintenance and replacement costs. Specifically, heating devices are usually made of specific materials, and these materials require special treatment to achieve the production of through holes. If the positions, sizes, shapes, and quantities of each opening are different, customized production needs to be carried out for each case.

[0039] This customized production process is not only complex but also requires additional time and labor, thus increasing the manufacturing cost.

[0040] In terms of processing technology, opening through holes on the heating device requires precise processing technologies such as laser cutting, CNC machining, etc. These technologies have high requirements, high costs, and require high-precision equipment and technical personnel for operation. And the materials of heating devices usually have high hardness or heat resistance, making it difficult to perform precise processing on them, further increasing the production cost.

[0041] Most importantly, different dies are required for through-holes of each different size and shape, and the manufacturing and replacement costs of the dies are relatively high. After the dies are worn, they need to be repaired or replaced, further increasing the costs. When the opening parameters change, the dies need to be redesigned and manufactured, which results in an extended production cycle and increased costs. To solve the above defects, an embodiment of the present utility model provides a glass cracking device. Specifically, reference can be made to Figure 1 , Figure 1 which is a schematic structural diagram of the glass cracking device in an embodiment of the present utility model.

[0042] The present utility model provides a glass cracking device, which includes:

[0043] a heating device 100 for generating heat;

[0044] a first heat conducting member 200, a first through-hole 200a having the same shape as the target opening on the glass 800 to be opened, corresponding to the target opening position, and a size greater than or equal to the target opening size is provided through the first heat conducting member 200. One side of the first heat conducting member 200 is thermally connected to the heating device 100, and the other side of the first heat conducting member 200 is used for thermally connecting at least a partial area of other parts of the glass 800 to be opened except the target opening.

[0045] In this embodiment, the heating device 100 is mainly used for generating heat. Specifically, the heating device 100 can adopt different forms such as a resistance heater, an infrared heater, etc. Among them, the resistance heater is a device that uses the thermal effect generated when an electric current passes through a conductive material for heating. Specifically, the resistance heater internally contains materials with high resistivity, such as nickel-chromium alloy, iron-chromium-aluminum alloy, etc. These materials are made into wire shapes or strip shapes and are arranged in a spiral shape or other shapes inside the heater.

[0046] During the heating process, when an electric current passes through the resistance material, according to Joule's law (Q = I 2 Rt), heat is generated on the resistance material. The current intensity (I), the resistance value (R) of the resistance material, and the energization time (t) determine the generated heat. The heat generated by the resistance material is transferred to the object to be heated through conduction, convection, and radiation. For example, in the glass cracking device, the heat generated by the resistance heater is conducted to the first heat conducting member 200 and then transferred to the glass 800.

[0047] The infrared heater, on the other hand, uses the method of infrared radiation for heating. Specifically, the infrared heater generates infrared radiation by means of electric heating or gas heating, so that a heating element (such as a quartz tube, carbon fiber, ceramic, etc.) generates infrared radiation.

[0048] The first heat conducting member 200 in this embodiment is mainly used to conduct the heat generated by the heating device 100, and is provided with a first through hole 200a running through it, which has the same shape as the target opening shape on the glass 800 to be opened, corresponding position to the target opening position, and a size greater than or equal to the target opening size. One side of the first heat conducting member 200 is thermally connected to the heating device 100, and the other side is used to thermally connect at least a partial area of other parts of the glass 800 to be opened except the target opening. Among them, the material of the first heat conducting member 200 can adopt highly heat conductive metals such as copper or aluminum to ensure efficient heat conduction.

[0049] In this embodiment, the heating device 100 is mainly used to generate heat, and the main function of the first heat conducting member 200 is to transfer the heat generated by the heating device 100 to the glass 800 to be opened, so as to heat a preset area. For example, after a preset path is cut on the glass 800 by laser, the glass 800 is placed on the first heat conducting member 200. The first through hole 200a on the first heat conducting member 200 corresponds to the position, shape and size of the target opening on the glass 800. After the heating device 100 is started, the heat is transferred to the area outside the closed path on the glass 800 through the first heat conducting member 200, so that a large enough crack is generated due to the temperature difference inside and outside the path, and the glass 800 automatically falls off along the preset path to form the target opening. In such a scenario, the accuracy and efficiency of chip separation can be effectively improved.

[0050] In the technical solution of this embodiment, by adopting the combination of the heating device 100 and the first heat conducting member 200, the heat generated by the heating device 100 can be efficiently transferred to the preset area of the glass 800 to be opened through the first heat conducting member 200. The design of the first through hole 200a on the first heat conducting member 200 enables it to be flexibly adjusted according to the specific shape and size of the opening on the glass 800. Compared with the method of directly setting through holes on the heating device 100, setting through holes on the first heat conducting member 200 in this embodiment can significantly reduce costs. The reason for the high cost in the related technology is that when setting through holes on the heating device 100, it needs to be specially made according to the position, size, shape and quantity of the opening. When any one of these parameters changes, the metal heating plate needs to be remade, resulting in a significant increase in production costs. While setting through holes on the first heat conducting member 200 can adapt to different opening requirements by replacing the first heat conducting member 200 instead of the entire heating component, greatly reducing the replacement cost and time, and improving the flexibility and efficiency of production. In summary, through optimized design, the utility model realizes lower costs, higher efficiency and a more flexible production process.

[0051] Furthermore, the first heat conducting member 200 is a rigid heat conducting plate.

[0052] In this embodiment, the rigid heat-conducting plate can be made of a variety of high thermal conductivity materials to ensure efficient heat conduction. Specific materials can include copper plates, aluminum plates, graphite plates, and so on.

[0053] Specifically, copper has extremely high thermal conductivity, with a thermal conductivity of about 400 W / (m·K), and it performs excellently in heat transfer. Using a copper plate as the heat-conducting plate can ensure that the heat generated by the heating device 100 is quickly and evenly transferred to the surface of the glass 800.

[0054] The thermal conductivity of aluminum is second only to that of copper, with a thermal conductivity of about 237 W / (m·K). The aluminum plate not only has good thermal conductivity but also has the advantages of light weight and low cost, making it very suitable for large-scale production and application.

[0055] The thermal conductivity of graphite material is also very high, reaching 1500 W / (m·K). The graphite plate has good thermal stability and high-temperature resistance characteristics, and can maintain excellent thermal conductivity in a high-temperature environment.

[0056] The reason for using the rigid heat-conducting plate is that the rigid heat-conducting plate can quickly transfer the heat generated by the heating device 100, enabling the surface of the glass 800 to quickly reach the preset temperature, improving the heating efficiency. Moreover, the rigid heat-conducting plate has good mechanical strength and stability, is not easily deformed, and ensures good contact and heat conduction effects in a high-temperature environment.

[0057] In terms of cost, there are various materials for the rigid heat-conducting plate. The selection of materials such as copper, aluminum, and graphite makes the production cost controllable. Appropriate materials can be selected according to specific application requirements to balance performance and cost. In addition, the rigid heat-conducting plate can be processed by conventional mechanical processing techniques (such as cutting, punching, polishing, etc.). It is relatively simple to fabricate through holes and other complex structures, reducing the manufacturing difficulty and cost.

[0058] Refer to Figure 1 、 Figures 3 to 6 , Figure 3 which is a schematic structural diagram of the glass in an embodiment of the present utility model, Figure 4 which is a schematic structural diagram of the glass cracking device in an embodiment of the present utility model, Figure 5 which is a schematic structural diagram of the glass cracking device in an embodiment of the present utility model, Figure 6 which is a schematic structural diagram of the glass cracking device in an embodiment of the present utility model.

[0059] In this embodiment, the glass cracking device further includes:

[0060] The second heat-conducting member 300 is a flexible heat-conducting member laminated on the side of the rigid heat-conducting plate facing away from the heating device 100. At a position of the second heat-conducting member 300 facing the first through hole 200a, a second through hole 300a having the same shape as the first through hole 200a and the same size as the first through hole 200a is formed. The second heat-conducting member 300 is used for thermally connecting the rigid heat-conducting plate and the glass 800 to be perforated.

[0061] In this embodiment, the second heat-conducting member 300 is mainly used to fill the tiny gap between the rigid heat-conducting plate and the glass 800 to be perforated. Since there may be tiny unevenness between the surfaces of the rigid heat-conducting plate and the glass 800, direct contact may cause uneven heat conduction. By providing a flexible heat-conducting member, these gaps can be effectively filled, ensuring uniform heat transfer and improving the overall heat conduction efficiency.

[0062] Specifically, the second heat-conducting member 300 can be made of high heat-conductivity materials such as flexible silica gel, thermal grease, and thermal rubber. These materials have good flexibility and heat-conducting performance and can closely adhere between the surfaces of the rigid heat-conducting plate and the glass 800 to achieve more efficient heat conduction. The heat-conductivity coefficient and thickness of the flexible heat-conducting member can be selected and adjusted according to specific application requirements.

[0063] In summary, the setting of the second heat-conducting member 300 can not only fill the tiny gap between the rigid heat-conducting plate and the glass 800, ensuring uniform heat transfer, but also improve the overall heat conduction efficiency of the glass cracking device. By providing the second through hole 300a corresponding to the first through hole 200a on the second heat-conducting member 300, the continuity and consistency of heat transfer are further ensured, thereby realizing a more accurate and efficient glass 800 perforation process.

[0064] Refer to Figure 2 , Figure 2 which is a schematic structural diagram of the glass cracking device in another embodiment of the present invention.

[0065] In this embodiment, the glass cracking device further includes a release film 400, and the release film 400 is disposed on the side of the second heat-conducting member 300 facing away from the rigid heat-conducting plate.

[0066] In this embodiment, the release film 400 can be made of a variety of high-performance materials, including polytetrafluoroethylene (PTFE) film, silicone rubber film, polyester (PET) film, etc. The PTFE film has a low friction coefficient and high temperature resistance and is very suitable for demolding operations in high-temperature environments. The silicone rubber film has good flexibility and heat resistance and can closely adhere to the second heat-conducting member 300 while ensuring easy separation from the surface of the glass 800. The PET film has excellent mechanical strength and chemical corrosion resistance and is suitable for a variety of industrial environments.

[0067] Specifically, the provision of the release film 400 can effectively prevent the second heat conducting member 300 from adhering to the surface of the glass 800 during the heating process. When the glass splitting device is working, the second heat conducting member 300 conducts heat to the glass 800 through the release film 400 to complete the heating of the area outside the closed path. After the heating process ends, the release film 400 ensures that the second heat conducting member 300 can be easily separated from the surface of the glass 800 without leaving any residues or damaging the surface of the glass 800, ensuring the quality of the cut glass 800 is intact.

[0068] By providing the release film 400 on the side of the second heat conducting member 300 facing away from the rigid heat conducting plate, not only can the stability and uniformity of the heat conduction effect be ensured during the heating process, but also the second heat conducting member 300 and the glass 800 can be easily separated after the heating process ends, improving the work efficiency and product quality.

[0069] Continue to refer to Figure 1 、 Figure 2 In this embodiment, the first heat conducting member 200 is provided with a plurality of first through holes 200a, and at the positions of the second heat conducting member 300 facing the first through holes 200a, a plurality of second through holes 300a are constructed, which have the same shape as the first through holes 200a and the same size as the first through holes 200a.

[0070] In this embodiment, the provision of the plurality of first through holes 200a and second through holes 300a is mainly for enabling heat transfer for multiple openings to be carried out simultaneously in one operation process. This design is applicable to occasions where multiple holes need to be opened on the glass 800, such as the glass 800 panel of a gas stove top. A gas stove usually requires multiple burner holes (generally, a household stove usually has two burners). By providing a plurality of corresponding through holes on the first heat conducting member 200 and the second heat conducting member 300, these holes can be cut simultaneously in one heating operation, greatly improving the production efficiency.

[0071] Specifically, when the glass 800 is placed on the glass splitting device, the second heat conducting member 300 transfers heat to the corresponding area of the glass 800 through the plurality of second through holes 300a. The laser pre-cuts a closed path on the glass 800, and then heats the area of the glass 800 outside the closed path. Sufficiently large cracks are generated inside and outside the closed path through the thermal expansion and contraction effect, causing the glass 800 to automatically fall off along the preset path, forming multiple target openings at one time.

[0072] In this embodiment, by providing a plurality of through holes on the first heat conducting member 200 and the second heat conducting member 300, the function of cutting multiple holes simultaneously can be achieved. This design not only improves the work efficiency of the glass splitting device, but also is applicable to application scenarios that require high precision and multi-hole cutting, such as the glass 800 panel of a gas stove top.

[0073] Continue to refer toFigure 1 , in this embodiment, the glass fragmenting device further includes:

[0074] A third heat conducting member 500, which is a flexible heat conducting member laminated between the rigid heat conducting plate and the heating device 100.

[0075] In this embodiment, the main function of the third heat conducting member 500 is to fill the tiny gap between the rigid heat conducting plate and the heating device 100, ensuring that heat can be transferred to the rigid heat conducting plate efficiently and uniformly. Since there may be uneven surfaces between the rigid heat conducting plate and the heating device 100, direct contact may lead to non-uniform heat conduction. By setting the flexible heat conducting member, similar to the second heat conducting member 300, these gaps can be effectively filled, ensuring uniform heat transfer and improving the overall heat conduction efficiency.

[0076] Specifically, the third heat conducting member 500 can adopt a high thermal conductivity flexible material similar to the second heat conducting member 300, such as flexible silica gel, thermal conductive silicone grease, thermal conductive rubber, etc. These materials have good flexibility and thermal conductivity, and can closely fit between the rigid heat conducting plate and the heating device 100 to achieve more efficient heat conduction. The thermal conductivity coefficient and thickness of the flexible heat conducting member can be selected and adjusted according to specific application requirements to optimize the heat transfer effect.

[0077] In this embodiment, by setting the third heat conducting member 500 between the rigid heat conducting plate and the heating device 100, not only can the tiny gap be filled to ensure uniform heat transfer, but also the overall heat conduction efficiency and performance of the glass fragmenting device can be improved. The application of the flexible heat conducting member makes the heat transfer more uniform and efficient during the heating process, thereby improving the quality and precision of the opening of the glass 800. At the same time, using the flexible heat conducting member can simplify the assembly and maintenance process of the device and improve the operation convenience.

[0078] In some embodiments, the first heat conducting member 200 is a metal heat conducting plate. The specific material can include copper plates, aluminum plates, etc. Copper has extremely high thermal conductivity, with a thermal conductivity of about 400 W / (m·K), and has good ductility and corrosion resistance. Using a copper plate as the heat conducting plate can ensure that the heat generated by the heating device 100 is quickly and uniformly transferred to the surface of the glass 800, improving the heat transfer efficiency and cutting precision. The thermal conductivity of aluminum is second only to that of copper, with a thermal conductivity of about 237 W / (m·K). At the same time, aluminum materials are light in weight and low in cost. The aluminum plate has good thermal conductivity, can reduce the overall weight of the device, is suitable for large-scale production and application, and reduces the production cost.

[0079] Refer to Figure 1 and Figure 2 , in this embodiment, the heating member includes:

[0080] The metal heat conduction base 101, one side of the metal heat conduction base 101 is thermally connected to one side of the first heat conduction member 200;

[0081] The electric heating component 102, at least part of the electric heating component 102 is embedded in the metal heat conduction base 101, and the electric heating component 102 is used for the metal heat conduction base 101.

[0082] In this embodiment, the metal heat conduction base 101 of the heating member can be made of materials with high thermal conductivity and high temperature resistance, such as aluminum alloy, stainless steel or ceramic materials, to ensure that it can maintain structural stability and high-efficiency heat conduction in a high-temperature environment. The electric heating component 102 can be a resistance wire, a heating tube or a heating film. These components are installed inside the metal heat conduction base 101 and generate heat by connecting to a power source.

[0083] The electric heating component 102 generates Joule heat by the current flowing through the resistance material, transfers the heat to the metal heat conduction base 101, and thus heats the surface of the metal heat conduction base 101. To improve the heating efficiency and uniformity, the design of the metal heat conduction base 101 can include heat conduction fins or a heat distribution layer to ensure that the heat can be evenly distributed to the entire surface of the heating member.

[0084] In practical applications, the glass cracking device provides energy for the electric heating component 102 through a power source. After the electric heating component 102 is powered on, it quickly generates heat and transfers the heat to the metal heat conduction base 101. After the metal heat conduction base 101 is heated, its surface temperature gradually rises, and the heat is transferred to the surface of the glass 800 to be cracked through the heat conduction member. For example, during the glass cracking process, the glass 800 is placed on the heating member, and the heating member quickly transfers the heat to the surface of the glass 800, causing the area of the glass 800 outside the closed path to expand due to heat, forming a temperature difference with the cooling area inside the closed path, thereby generating cracks and achieving precise cutting of the glass 800. This method not only improves the cracking efficiency but also ensures the cutting accuracy and quality.

[0085] In this embodiment, by setting the electric heating component 102 in the heating member, efficient and precise heat control can be achieved, ensuring the stability and controllability of the heating process. The electric heating component 102 has the advantages of fast heating speed, wide adjustable temperature range, high energy utilization rate, etc. The metal heat conduction base 101 is made of a material with high thermal conductivity, which can quickly transfer and distribute heat, improving the overall heating efficiency. Since the electric heating component 102 is installed inside the metal heat conduction base 101, the structure is compact, which is convenient for maintenance and replacement, further reducing the maintenance cost and operation difficulty of the equipment.

[0086] A glass hole-opening device further proposed by the present utility model includes a laser cutting device and a glass splitting device. The specific structure of the glass splitting device refers to the above-mentioned embodiments. Since the glass hole-opening device adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the technical effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here. Among them, the laser cutting device is used to cut a closed contour line on the glass 800 to be opened; the glass splitting device is used to heat at least part of the area of other parts of the glass 800 to be opened except the target opening after the laser cutting device cuts the closed contour line on the glass 800 to be opened.

[0087] In this embodiment, first, two circular closed trajectories with a diameter of 150 mm are cut on the 6-mm-thick glass 800 by using picosecond laser (as Figure 2 shown). The picosecond laser ensures the formation of precise and smooth circular trajectories on the glass 800 with its high precision and fast cutting ability.

[0088] Subsequently, the cut glass 800 is moved directly above the splitting device to ensure that the cutting trajectory is aligned with the hole-opening position of the splitting device. The opening diameters of the flexible thermal conductive interface material and the metal plate are both 160 mm, and the opening positions are concentric with the circular trajectories on the glass 800. This step ensures the heat transfer efficiency and precision during the subsequent heating process. The heating device 100 starts to heat and is kept at a constant temperature of 150 °C, and the heat is evenly transferred to the surface of the glass 800 through the flexible thermal conductive interface material. During this process, the flexible thermal conductive interface material fills the gap between the glass 800 and the metal plate, ensuring efficient heat transfer.

[0089] After heating for a preset time (such as 20 seconds), the temperature rise of the part outside the circular trajectory of the glass 800 exceeds 50 degrees, resulting in a large enough temperature difference (cracks of 10 - 20 μm) between the areas inside and outside the closed trajectory. Due to the thermal expansion and contraction effect, cracks are generated between the circular area and the glass 800 substrate, and the circular area automatically falls off from the glass 800 substrate, thus completing the hole opening.

[0090] Through the above processing process, the glass hole-opening device of the present utility model can efficiently and precisely cut the required holes on the glass 800. The laser cutting device provides high-precision initial cutting, and the glass splitting device realizes the splitting of the glass 800 by rapid heating using the principle of thermal expansion and contraction. The whole process not only improves the processing efficiency, but also ensures the quality and precision of the cutting, reducing the processing cost and time.

[0091] In some embodiments, the glass punching device further includes a carbon dioxide heating device, which is used to heat the closed contour line after the laser cutting device cuts out the closed contour line on the glass 800 to be punched and before the glass splitting device heats the glass 800 to be punched.

[0092] In this embodiment, the carbon dioxide heating device is used to heat the target punching shape cut out by the laser cutting device on the glass 800. By adding this heating step, the splitting process can be assisted, making the glass splitting more efficient and accurate.

[0093] In these embodiments, the glass punching device includes three main parts: a laser cutting device, a glass splitting device, and a carbon dioxide heating device. The laser cutting device is used to cut out the target punching shape on the glass 800; the glass splitting device is used to heat at least part of the area of the glass 800 to be punched except for the target punching; the carbon dioxide heating device is specifically used to heat the target punching shape cut out by the laser. The glass splitting device still preheats through its heating member, but a carbon dioxide heating step is added to ensure that the splitting process is more stable and efficient.

[0094] In practical applications, first, two circular closed trajectories with a diameter of 150 mm are cut out on the glass 800 with a thickness of 6 mm, for example, using picosecond laser (as Figure 2 shown).

[0095] Then the cut glass 800 is moved directly above the splitting device to ensure that the cutting trajectory is aligned with the punching position of the splitting device. The opening diameters of both the flexible thermal conductive interface material and the metal plate are 160 mm, and the punching positions are concentric with the circular trajectories on the glass 800.

[0096] After laser cutting, the carbon dioxide heating device is used to heat the target punching shape. The carbon dioxide heating device provides directional heat to further heat the cutting path, which helps to generate greater thermal stress.

[0097] The splitting device quickly heats the area outside the circular trajectory and keeps it at a constant temperature of 150 °C, and the heat is evenly transferred to the surface of the glass 800 through the flexible thermal conductive interface material. In this process, the flexible thermal conductive interface material fills the gap between the glass 800 and the metal plate, ensuring efficient heat transfer.

[0098] After 20 seconds of heating, the temperature rise of the part outside the circular trajectory of the flat glass 800 exceeds 50 degrees, resulting in a large enough temperature difference (cracks of 10 - 20 μm) between the areas inside and outside the closed trajectory. Due to the thermal expansion and contraction effect, cracks are generated between the circular area and the glass 800 substrate, and the circular area automatically falls off from the glass 800 substrate, thus completing the punching.

[0099] In this embodiment, by adding a carbon dioxide heating device to the glass punching equipment, the efficiency and precision of the chipping process can be further improved. The auxiliary heating step of the carbon dioxide heating device makes the glass chipping after laser cutting smoother, reducing the problem of irregular cracks caused by uneven heating. At the same time, the glass chipping device still preheats through its heating component to ensure the efficient operation of the chipping device.

Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the overall concept of the present utility model, or any direct / indirect application in other related technical fields, is included in the scope of protection of the present utility model.
