[0038] In one embodiment, Figure 1 As shown, the embodiment of the present application provides a glass chamfering processing method, and the glass chamfering processing method may specifically include the following steps:

[0039] Step S110: Provide a laser and an SLM shaping module, and perform a preset shaping operation on the initial laser beam by changing the phase and / or amplitude of the initial laser beam emitted by the laser through spatial light modulation performed by the SLM shaping module, so as to project a laser spot with a preset shape onto the laser working surface.

[0040] It can be understood that the glass chamfering method of the embodiment of the present application can be specifically applied to the chamfering process of glass products that need to have smooth chamfers, so as to process the glass sheets to be chamfered into glass products that meet the corresponding requirements. In order to better match the chamfered shape of the glass product to further improve the chamfering accuracy and efficiency of the corresponding glass product, the present method step will provide a SLM (Spatial Light Modulator) shaping module while providing a laser for laser chamfering operation, so as to change the phase and / or amplitude of the initial laser beam emitted by the laser through spatial light modulation performed by the SLM shaping module, so as to perform a preset shaping operation on the initial laser beam, so as to project a laser spot with a preset shape on the laser working surface, and the preset shape can be any shape that is convenient for laser chamfering processing, so that the subsequent method steps can better perform the corresponding laser chamfering operation through the laser spot.

[0041] Step S120: providing a glass sheet to be chamfered, and performing a laser chamfering operation on the glass sheet to be chamfered by using a laser spot to obtain a target glass product.

[0042] It can be understood that after obtaining a laser spot with a preset shape through the above method steps, the laser spot can be further used to perform laser chamfering operations on the glass sheet to be chamfered to obtain a target glass product, that is, by laser cutting, the four corners of the glass sheet to be chamfered are subjected to corresponding chamfering cutting operations so that the shape of the edge of the glass sheet to be chamfered meets the corresponding shape requirements of the target glass product.

[0043] In this way, in the glass chamfering method provided in the embodiment of the present application, the chamfering operation of the entire glass product completed through the above-mentioned method steps is mainly completed quickly by laser, and does not involve the operation of the tool. Therefore, there will be no problems such as tool vibration and rapid tool wear that affect the chamfering processing accuracy and chamfering processing efficiency. At the same time, by using a laser spot with a preset shape to better match the chamfering shape of the product to be chamfered, its chamfering processing efficiency and chamfering processing accuracy can be further improved.

[0044] In some examples, the specific process of executing the above method step of "changing the phase and / or amplitude of the initial laser beam emitted by the laser through spatial light modulation performed by the SLM shaping module to perform a preset shaping operation on the initial laser beam" is as follows: using the phase map pre-generated by the SLM shaping module, the initial laser beam is loaded with preset phase compensation and / or amplitude control information to accurately modulate the phase and / or amplitude of the initial laser beam, thereby completing the preset shaping operation. In this way, through this method step, the corresponding SLM shaping module can be quickly configured through the pre-generated phase map, so that the corresponding SLM shaping module can quickly and accurately complete the phase and / or amplitude modulation of the initial laser beam, thereby better completing the preset shaping operation.

[0045] It can be understood that the pre-generated phase map mentioned in this example should be adapted to the preset shape of the laser spot that is ultimately desired to be obtained, so as to ensure that the preset phase compensation and / or amplitude control information loaded on the initial laser beam can ultimately obtain a target laser beam that can form a laser spot with a preset shape.

[0046] In some examples, the SLM shaping module includes a 95° prism, a spatial light modulator, a 4F lens combination and an objective lens, wherein the 95° prism can be specifically located in the optical path of the initial laser beam, and is mainly used to perform a preset deflection process on the initial laser beam so that it enters the spatial light modulator. The spatial light modulator can be specifically used to load preset phase compensation and / or amplitude control information on the deflected initial laser beam through a pre-generated phase map, so as to accurately modulate the phase and / or amplitude of the deflected initial laser beam to obtain the initial laser beam after preliminary modulation. The 4F lens combination can be specifically located in the optical path of the initial laser beam after preliminary modulation, and is mainly used to further modulate the initial laser beam after preliminary modulation in the frequency domain to obtain the initial laser beam after further modulation. The objective lens can be specifically located in the optical path of the further modulated initial laser beam, and is mainly used to focus the further modulated initial laser beam to project it onto the laser working surface to form a laser spot. In this way, through the above-mentioned structural setting, when the initial laser beam passes through the SLM shaping module, it can successively pass through the 95° prism, spatial light modulator, 4F lens combination and objective lens and other structures to cooperate accordingly, so as to better complete the SLM shaping operation of the initial laser beam and obtain the required laser spot on the laser working surface.

[0047] It is understandable that the spatial light modulator (SLM) mentioned above can generate a preset phase diagram through an electronic modulation device such as liquid crystal, electro-optical or micro-electromechanical system (MEMS) configuration to achieve precise modulation of the laser phase and amplitude, that is, by loading specific phase compensation or amplitude control information on the SLM, the shape and characteristics of the laser beam can be modulated. The 4F lens combination mentioned above is a commonly used optical configuration, which may include two lenses with equal focal lengths for Fourier transform and inverse Fourier transform to modulate the laser beam in the frequency domain.

[0048] In some examples, the SLM shaping module also includes a beam expander, which is located in the optical path of the initial laser beam, for expanding the initial laser beam and allowing the expanded initial laser beam to enter the 95° prism. In this way, through the above-mentioned structural setting, when the initial laser beam passes through the SLM shaping module, the initial laser beam can be expanded by the beam expander first to increase the diameter of the initial laser beam so that its diameter can better meet the corresponding SLM shaping requirements, and then the corresponding SLM shaping operation is performed through the subsequent optical elements of the SLM shaping module to better obtain the required laser spot. Further, the SLM shaping module also includes a half-wave plate, which is located in the optical path of the initial laser beam, for adjusting the linear polarization angle of the initial laser beam, and allowing the initial laser beam after the angle adjustment to enter the beam expander. In this way, the structural setting of the half-wave plate can be used to adjust the linear polarization angle of the initial laser beam through the half-wave plate before the initial laser beam is expanded through the beam expander, so that its linear polarization angle can also better meet the corresponding SLM shaping requirements. In addition, the SLM shaping module may also include a plurality of reflectors, so that the optical path of the initial laser beam becomes more reasonable in the SLM shaping module through the structural arrangement of the plurality of reflectors, so as to optimize the spatial layout of the entire SLM shaping module.

[0049] In some examples, such as Figure 2 As shown, the preset shape mentioned in the above method steps can be a discrete point shape in the shape of an eight, that is, Figure 2 The structure shown by the dashed line in the middle, at this time, Figure 3 As shown, the process of executing the above method step of "performing a laser chamfering operation on the glass sheet to be chamfered by using a laser spot to obtain a target glass product" is specifically as follows:

[0050] Step S121: projecting a laser spot onto the side surface of the glass sheet to be chamfered, and rotating the glass sheet to be chamfered with the center of the front surface of the glass sheet to be chamfered as the rotation center, so that a hidden crack line is formed at each of the four corners of the glass sheet to be chamfered.

[0051] Step S122: performing a cracking process on the glass sheet to be chamfered having the hidden crack line, so that the four corners of the glass sheet to be chamfered are cracked along the corresponding hidden crack line, thereby obtaining a target glass product.

[0052] It is understandable that if Figure 2 As shown, the side surface 120 of the glass sheet to be chamfered mentioned in the method step can specifically refer to the surface formed by the edge of the glass sheet to be chamfered in the width direction and the edge of the glass sheet to be chamfered in the thickness direction, or can refer to the surface formed by the edge of the glass sheet to be chamfered in the length direction and the edge of the glass sheet to be chamfered in the thickness direction. The front surface 110 of the glass sheet to be chamfered mentioned in the method step specifically refers to the surface formed by the edge of the glass sheet to be chamfered in the length direction and the edge of the glass sheet to be chamfered in the width direction. Since the preset shape is an eight-shaped discrete point, when the laser spot with the preset shape is projected onto the side surface of the glass sheet to be chamfered, and the center of the front surface 110 of the glass sheet to be chamfered is used as the rotation center, when the glass sheet to be chamfered is rotated, a hidden crack line can be formed at each of the four corners of the glass sheet to be chamfered, and the shape of the hidden crack line on the front surface 110 should be an arc. Next, when the glass sheet to be chamfered with the hidden crack line is further cracked so that the four corners of the glass sheet to be chamfered are cracked along the corresponding hidden crack line, the target glass product can be well obtained, that is, the four corners of the target glass product all form the required arc chamfers.

[0053] In this way, through the above method steps, it is possible to form a laser processing method that first forms a corresponding hidden crack line on the glass piece to be chamfered through laser spot processing, and then performs crack processing on the glass piece to be chamfered based on the corresponding hidden crack line. Compared with the existing Bessel cutting method, this laser processing method can directly form the required arc chamfers on the four corners of the target glass product without the problem of the Bessel cutting method being prone to edge breakage and cracks caused by extrusion due to the occurrence of right-angled edges during the cutting process. That is, its chamfering processing effect is better.

[0054] In some examples, the process of executing the above method step of "projecting the laser spot onto the side surface of the glass sheet to be chamfered, and rotating the glass sheet to be chamfered with the center of the front surface of the glass sheet to be chamfered as the rotation center, so that a hidden crack line is formed at each of the four corners of the glass sheet to be chamfered" is specifically as follows: providing a horizontal motion module, adjusting the position of the glass sheet to be chamfered by the horizontal motion module, so as to project the laser spot onto the target position of the side surface of the glass sheet to be chamfered; providing a rotational motion module, driving the glass sheet to be chamfered by the rotational motion module, rotating with the center of the front surface of the glass sheet to be chamfered as the rotation center, so that a hidden crack line is formed at each of the four corners of the glass sheet to be chamfered. In this way, through the above method steps, it is possible to ensure that the laser spot is accurately projected onto the target position of the side surface of the glass sheet to be chamfered by respectively coordinating the horizontal motion module and the rotational motion module, so that the four corners of the glass sheet to be chamfered can more stably form a hidden crack line.

[0055] It is understandable that the horizontal motion module mentioned above can be specifically a conventional motion module, which is driven by a cylinder or a motor to drive the glass piece to be chamfered to move in the first horizontal direction and / or the second horizontal direction. To ensure that the glass piece to be chamfered can move to any position on the corresponding horizontal plane, the first horizontal direction mentioned above should be perpendicular to the second horizontal direction. Similarly, the rotational motion module mentioned above can also be specifically a conventional motion module, which is driven by a motor to drive the glass piece to be chamfered to perform corresponding rotational motion.

[0056] In some examples, the process of executing the above method step of "performing a cracking process on the glass sheet to be chamfered with a hidden crack line, so that the four corners of the glass sheet to be chamfered are cracked along the corresponding hidden crack line to obtain a target glass product" is specifically as follows: performing a cracking process by applying external forces to the four corners of the glass sheet to be chamfered with the hidden crack line, so that the four corners of the glass sheet to be chamfered are cracked along the corresponding hidden crack line to obtain a target glass product. In this way, through the above method steps, it is possible to quickly complete the corresponding cracking process by applying external forces, so as to better obtain the corresponding target glass product.

[0057] It is understandable that the method of applying external force mentioned in this example can be a mechanically assisted method, such as using a manipulator or other downward pressing block structure to apply external force to the four corners of the glass sheet to be chamfered with the hidden crack line to complete the corresponding cracking process. It can also be a manual method, that is, manually gently bending the four corners of the glass sheet to be chamfered to quickly complete the corresponding cracking process.

[0058] In some examples, the process of executing the above method step of "performing a crack treatment on the glass piece to be chamfered having a hidden crack line, so that the four corners of the glass piece to be chamfered are cracked along the corresponding hidden crack line to obtain a target glass product" is specifically as follows: the glass piece to be chamfered having a hidden crack line is subjected to a crack treatment by acid pickling the cut surface through wet chemical etching, so that the four corners of the glass piece to be chamfered are cracked along the corresponding hidden crack line to obtain a target glass product. In this way, through the above method steps, it is possible to quickly complete the corresponding crack treatment through wet chemical etching to better obtain the corresponding target glass product. Compared with the previous method of applying external force, the wet chemical etching method can make the chamfered edge of the target glass product obtained in the end smoother, that is, the chamfering effect of the target glass product obtained in the end is better.

[0059] It can be understood that the wet chemical etching mentioned in this example can specifically be a conventional wet chemical etching process, that is, by immersing a specific part of the glass sheet to be chamfered with a hidden crack line in a specific etching liquid, so that the chemical components in the liquid react with the material at the hidden crack line, so that the four corners of the glass sheet to be chamfered are cracked along the corresponding hidden crack line, thereby obtaining the target glass product.

[0060] In one embodiment, the embodiment of the present application also provides a glass chamfering processing device, which may specifically include a laser, an SLM shaping module, a horizontal motion module, a rotational motion module, a memory, a processor, and a program stored on the memory and running on the processor. When the program is executed by the processor, the specific steps of the glass chamfering processing method in the above embodiment are implemented, as described above and will not be repeated here.

[0061] It should be noted that the above-mentioned glass chamfering processing device and the above-mentioned glass chamfering processing method embodiment belong to the same concept, and the specific implementation process is detailed in the above-mentioned glass chamfering processing method embodiment, and the technical features in the above-mentioned glass chamfering processing method embodiment are correspondingly applicable in the glass chamfering processing device embodiment, which will not be repeated here.

[0062] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
