For example, when an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.
Furthermore, references herein to "an embodiment" mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
It should be noted that, for convenience of description, three coordinate axes perpendicular to each other in a defined space are an X axis, a Y axis, and a Z axis, wherein the X axis and the Y axis are two coordinate axes perpendicular to each other in the same horizontal plane, and the Z axis is a coordinate axis in a vertical direction, for example, a thickness direction of an edge film described below; the X axis, the Y axis and the Z axis are positioned on three planes which are mutually perpendicular in space and are respectively an XY plane, a YZ plane and an XZ plane, wherein the XY plane is a horizontal plane, the XZ plane and the YZ plane are vertical planes, and the XZ plane is perpendicular to the YZ plane.
An embodiment of the present invention provides a curved glass edge film cutting device (not shown) for cutting an edge film of a curved glass 200. It should be noted that the curved glass edge film cutting device is not only applicable to the curved glass 200, but also applicable to other objects with arc-shaped characteristics. For convenience of explanation, the curved glass 200 will be exemplified in this embodiment.
As shown in fig. 1 to 4, the curved glass edge film cutting device (not shown) includes a frame (not shown), a laser cutting assembly (not shown), a driving assembly (not shown), a visual inspection assembly (not shown), a control assembly (not shown), and a jig 100 for fixing a curved glass 200. Wherein the frame has a support platform (not shown) on which the laser cutting assembly is mounted for cutting the edge film of the curved glass 200.
In addition, the driving assembly is mounted on the supporting platform, the jig 100 is mounted on the driving assembly, and the jig 100 can move towards a direction approaching or far away from the laser cutting assembly under the driving of the driving assembly. Preferably, the drive assembly is a three-axis movement mechanism.
It should be noted that, the triaxial moving mechanism not only can realize accurate position control and motion control to the jig 100, improve cutting accuracy and stability, but also can control three directions of the jig 100 simultaneously, and improve cutting speed and working efficiency.
It can be appreciated that when the edge film on the curved glass 200 needs to be cut, the technician controls the driving assembly to move in a direction approaching the laser cutting assembly, so as to drive the jig 100 to move in a direction approaching the laser cutting assembly, thereby enabling the laser cutting assembly to cut the edge film of the curved glass 200 fixed on the jig 100. After the edge film on the curved glass 200 is cut, a technician only needs to control the driving assembly to move in a direction away from the laser cutting assembly, so as to drive the jig 100 to move in a direction away from the laser cutting assembly.
Of course, in other embodiments, the driving assembly may use a moving mechanism such as a linear guide, a lead screw guide, a stepper motor, etc., as long as accurate position control and motion control of the jig 100 can be achieved, which is not limited in the present invention, and those skilled in the art may select according to practical situations.
In addition, the vision inspection assembly is mounted on the support platform and located at the periphery of the jig 100, for obtaining the edge position of the curved glass 200, so as to more precisely control the cutting of the edge film of the curved glass 200 by the laser cutting assembly. In this embodiment, the visual detection component is a camera, and the edge position of the curved glass 200 is obtained by the camera, and the profile parameters of the curved glass 200 are obtained. In addition, the control assembly is arranged on a supporting platform of the frame and is respectively connected with the laser cutting assembly, the driving assembly and the visual detection assembly.
When the edge film of the curved glass 200 needs to be cut, a technician firstly fixes the curved glass 200 on the jig 100, then acquires the edge position of the curved glass 200 through the visual detection assembly, transmits acquired data to the control assembly, and then controls the jig 100 to relatively move with the laser cutting assembly along the contour line of the curved glass 200 according to the acquired data so as to cut the edge film of the curved glass 200.
Therefore, the cutting range and the cutting direction of the laser cutting assembly can be better controlled, so that a high-precision cutting effect can be achieved. Meanwhile, the quality of the curved glass 200 can be detected in the visual detection, so that the product meets the requirements, and the production efficiency and the product quality are greatly improved.
It should be noted that the relative movement includes movement along the contour line, and relative longitudinal cutting movement between the jig and the laser cutting assembly.
In order to better understand the solution of the present invention by those skilled in the art, the following description will clearly and completely describe the solution of the embodiment of the present invention with reference to fig. 1 to 4.
Further, as a specific implementation of some embodiments of the present invention, as shown in fig. 2 to 4, the jig 100 includes a substrate 110, a fixture 120, and a light source assembly 130 for irradiating a curved glass 200. Wherein, the substrate 110 is mounted at the output end of the driving assembly. In addition, the top of the fixture 120 has a contoured surface (not shown) that is adapted to the target to secure the curved glass 200 to the contoured surface.
In this embodiment, the substrate 110 is fixedly mounted on the output end of the driving assembly through a fastener (specifically, a screw, etc.), so that the driving assembly can drive the jig 100 to move rapidly and automatically, thereby realizing positioning and processing of the curved glass 200 at different positions and angles without disassembling and reinstalling the curved glass 200, and greatly improving the working efficiency.
In addition, in order to precisely polish the edge of the curved glass 200, the fixing member 120 and the light source assembly 130 are mounted on the substrate 110, and the light source assembly 130 surrounds the fixing member 120.
It can be appreciated that after the curved glass 200 is fixed on the fixing member 120, the technician turns on the light source assembly 130, and the light emitted by the light source assembly 130 irradiates the edge of the curved glass 200 to illuminate the edge of the curved glass 200, that is, illuminate the boundary between the edge film of the curved glass 200 and the curved glass 200 body, so that when the edge film on the curved glass 200 is cut later, the technician can more accurately position the edge film, and avoid damage to the curved glass 200 body, thereby improving the quality and efficiency of processing.
In addition, a gap (not shown) exists between the light source assembly 130 and the fixture 120. It should be noted that, the gap can be used for accommodating the edge film of the curved glass 200; secondly, the installation of the light source assembly 130 and the fixing piece 120 can be facilitated, the problem of interference during the installation of the light source assembly 130 and the fixing piece 120 is avoided, and the installation efficiency is improved.
Further, as a specific implementation of some embodiments of the present invention, the contoured surface of the fixing element 120 is an arc-shaped convex surface. Alternatively, in another alternative embodiment, the contoured surface of the mount 120 is a concave arcuate surface. Of course, in other embodiments, the fixing member 120 may have other suitable shapes, which are not limited in the present invention, and those skilled in the art may select the fixing member according to the actual situation.
Preferably, in this embodiment, as shown in fig. 2, the contoured surface of the fixture 120 is a hemispherical convex surface. It should be noted that hemispherical convexities can accommodate curved glass 200 workpieces of different shapes, including glass workpieces having widely varying radii of curvature and curvatures. And the spherical structure is beneficial to distributing pressure and reducing deformation and cracks in the cutting process.
In addition, compared with other profiling structures (such as prisms, ellipses and the like), the hemispherical structure is easier to process, process deviation is allowed in the manufacturing process, and mass production can be realized. Therefore, the curved glass 200 workpiece with different shapes can be better adapted by using the profiling surface with the hemispherical convex surface, and the curved glass workpiece has the advantages of easiness in processing, low production cost, high stability and the like.
Further, as a specific embodiment of the curved glass edge film cutting device provided by the present invention, as shown in fig. 2 to 3, in order to ensure the installation and positioning accuracy of the curved glass 200, the fixture 100 further includes a limiting member 140, where the limiting member 140 is installed on the substrate 110 and located at the periphery of the fixing member 120. When the curved glass 200 is placed on the profiling surface of the fixing element 120, the side wall of the limiting element 140 facing the fixing element 120 abuts against the curved glass 200 at the corresponding position, so as to limit the movement of the curved glass 200.
As can be appreciated, prior to cutting the edge film of the curved glass 200, the technician first places the curved glass 200 on the contoured surface of the fixture 120 and secures it; meanwhile, the side wall of the limiting member 140 facing the fixing member 120 abuts against the curved glass 200 at the corresponding position, so as to limit the movement of the curved glass 200.
It should be noted that, the fixture 100 realizes the stable fixation and the limitation of movement of the curved glass 200 through the combined action of the fixing piece 120 and the limiting piece 140, so as to avoid the problem of shaking of the curved glass 200, improve the precision of the edge film of the curved glass 200 in the subsequent cutting, and ensure the quality of the product.
Further, as a specific embodiment of the curved glass edge film cutting device provided by the invention, the contour of the inner side surface of the limiting member 140 is the same as the contour of the curved glass 200 at the corresponding position. It should be noted that, by adopting the design that the contour of the inner side surface of the limiting member 140 is the same as the outer contour of the curved glass 200, the curved glass 200 can be ensured to be completely attached to the inner side surface of the limiting member 140 when being placed in the limiting member 140, so that the position and angle of the curved glass 200 are fixed, the phenomena of movement, shaking or skew of the curved glass 200 in the processing process are avoided, and the processing precision and reliability are improved.
Of course, in other embodiments, the profile of the inner side surface of the limiting member 140 may be similar to the profile of the curved glass 200 at the corresponding position, which is not limited in the present invention, and may be selected by those skilled in the art according to practical situations.
In addition, the contour of the inner surface of the light source assembly 130 is the same as the contour of the curved glass 200 at the corresponding position, so as to ensure that the light source assembly 130 sufficiently shines the curved glass 200, and avoid the problems of a shining dead angle and that part of the curved glass 200 does not shine.
Further, as a specific embodiment of the curved glass edge film cutting device provided by the invention, in order to achieve more accurate cutting of the edge film of the curved glass 200 and improve the product quality and the processing efficiency, the curved glass edge film cutting device further comprises an induction component (not shown), wherein the induction component is mounted on the supporting platform and connected with the control component, and is used for measuring the thickness difference of the edge film of the curved glass 200.
It can be appreciated that in the process of cutting the edge film of the curved glass 200, the sensing component can detect the thickness of the edge film in real time, meanwhile, the measurement data of the sensing component can be transmitted to the control component, and the control component automatically adjusts the cutting parameters (specifically, parameters such as laser focus, energy, speed and the like) of the laser cutting component according to the transmitted measurement data so as to adapt to the edge films with different thicknesses, thereby realizing better cutting effect and reducing waste and processing reject ratio.
In this embodiment, the sensing component is a high-precision infrared sensor. By measuring the thickness difference of the edge film of the curved glass 200 by adopting the high-precision infrared sensor (the fixture 100 drives the curved glass 200 to rotate according to actual edge profile data, specific data (the height position based on the edge profile data) of the edge film of the curved glass 200 is obtained), and the thickness detection of the profile line 5mm in front of and behind the shrinking profile line can meet the requirements of customers.
Of course, in other embodiments, the sensing component may be other sensors, which are not limited in the present invention, and those skilled in the art may choose according to the actual situation.
Further, as a specific implementation mode of the curved glass edge film cutting device provided by the invention, the curved glass edge film cutting device further comprises a monitoring system (not shown), wherein the monitoring system is connected with the driving assembly, the laser cutting assembly, the visual detection assembly, the sensing assembly and the control assembly, so that when the laser cutting assembly cuts the curved glass 200 edge film, real-time monitoring and adjustment are performed, and the product quality is ensured.
It can be understood that when the laser cutting assembly cuts the edge film of the curved glass 200, the monitoring system can monitor the driving assembly, the laser cutting assembly, the visual detection assembly and the sensing assembly in real time, and transmit the monitored data to the control assembly, and the control assembly analyzes and processes the data, so that the cutting parameters (specifically, parameters such as laser focus, energy and speed) of the laser cutting assembly are further optimized and adjusted, and the cutting efficiency and quality of the edge film cutting device of the curved glass 200 are further improved.
Based on the above-mentioned curved glass edge film cutting device, the embodiment of the invention also provides a method for using the curved glass edge film cutting device, wherein, as shown in fig. 1, the method for using the curved glass edge film cutting device comprises the following steps:
s100, fixing the curved glass 200 with the edge film on the jig 100 to ensure that the curved glass 200 can keep stable positions and angles in the subsequent cutting process.
S200, the driving assembly drives the jig 100 to move along the contour line of the curved glass 200 towards the direction approaching (or away from) the laser cutting assembly, so as to ensure that the curved glass 200 can accurately enter (or leave) the laser cutting area.
It should be noted that, in the process of driving the jig 100 to move in a direction approaching or separating from the laser cutting assembly, the driving assembly may also spatially move, specifically, rotate, move in a z-axis direction, and the like.
S300, in the movement process of the jig 100, the visual detection component obtains the position of the edge of the curved glass 200 and obtains the profile parameters of the curved glass 200. Wherein the profile parameters include thickness, shape, etc.
Specifically, before the laser cutting, the driving component drives the fixture 100 to move one turn around the contour line of the curved glass 200, that is, drives the curved glass 200 to move one turn around its own contour line, so as to ensure that each point can pass through the shooting point.
And acquiring change data corresponding to the Y axis and the Z axis by cameras in different directions (right above and vertical side surfaces) at the shooting points by taking the X axis as a reference, and forming the actual contour position of the workpiece as the edge contour data of the current curved glass 200. It should be noted that the XY plane is the plane in which the top or mounting surface of the support platform is located.
S400, the control component adjusts the cutting parameters of the laser cutting component according to the profile parameters of the curved glass 200. It should be noted that, by analyzing parameters such as the contour and thickness of the curved glass 200, the control component can automatically adjust cutting parameters such as power, speed, distance, etc. of the laser cutting component, so as to ensure quality and accuracy of the cutting result.
Therefore, the driving jig 100 is realized through the steps, the edge film position and the profile parameters are determined, and the cutting parameters of the cutting assembly are adjusted, so that the accurate cutting of the edge film of the curved glass 200 is achieved, the processing efficiency and the product quality are improved, and various market demands can be met.
In summary, compared with the prior art, the using method of the curved glass edge film cutting device has at least the following beneficial effects: according to the using method of the curved glass edge film cutting device, the curved glass 200 edge film cutting device is provided with the jig 100 and the visual detection assembly, when the edge film of the curved glass 200 needs to be cut, a technician firstly fixes the curved glass 200 on the jig 100, then obtains the edge position of the curved glass 200 through the visual detection assembly, transmits obtained data to the control assembly, and then controls the laser cutting assembly to cut the edge film on the curved glass 200 according to the obtained data.
Thus, the cutting of the edge film of the curved glass 200 by the laser cutting assembly can be more precisely controlled, thereby realizing a high-precision cutting effect. In addition, the invention also provides functions of real-time monitoring, data analysis and optimization, which can help operators to adjust and optimize in real time in the cutting process, thereby improving the production efficiency and the product quality.
Further, as a specific implementation manner in some embodiments of the present invention, the method for using the curved glass edge film cutting device further includes the following steps:
s500, in the movement process of the jig 100, the thickness difference of the edge film of the curved glass 200 is measured through the sensing component so as to obtain the actual thickness of the curved glass 200 in real time, and the control component adjusts the cutting parameters of the laser cutting component in real time according to the actual thickness of the edge film of the curved glass 200.
It will be appreciated that first, the actual thickness of the edge film of the curved glass 200 is measured by the sensing assembly. In detail, the fixture 100 drives the curved glass 200 to rotate with actual edge profile data, wherein the sensing component obtains specific data of the edge film on the curved glass 200 (based on the height position of the edge profile data of the curved glass 200), and these data can be used to calculate the thickness of the edge film of the curved glass 200 and determine any possible thickness variation. Thus, in this manner, the sensing assembly can accurately measure the thickness of the edge film of the curved glass 200, thereby providing the necessary parameters for subsequent cutting operations.
Then, cutting parameters of the laser cutting assembly are adjusted in real time. Specifically, after the thickness of the edge film of the curved glass 200 is measured, the control component automatically adjusts the cutting parameters of the laser cutting component according to the data. It should be noted that these cutting parameters include laser focus, energy, and speed to ensure optimal laser contact and penetration of the curved glass 200 during cutting. Thus, not only the quality and cutting efficiency of the edge film of the curved glass 200 are ensured, but also the consistency and accuracy of processing are improved.
Further, as a specific implementation manner in some embodiments of the present invention, the method for using the curved glass edge film cutting device further includes the following steps:
s600, acquiring cutting parameters in real time through a monitoring system in the cutting process of the laser cutting assembly, and analyzing and processing the cutting parameters by the control assembly so as to optimize the cutting parameters of the laser cutting assembly and realize the optimal cutting effect and quality.
It should be noted that, in the process of cutting the edge film of the curved glass, the monitoring system monitors the cutting parameters (specifically, parameters such as the speed, the power, the frequency, etc. of the laser cutting, and various indexes such as the cutting quality and the processing efficiency) generated by the laser cutting at any time through the control component. The monitoring system acquires the cutting parameters in real time and transmits the cutting parameters to the control component, and the control component can analyze and process the cutting parameters to determine an optimization strategy of the laser cutting parameters.
Specifically, the control component continuously adjusts the cutting parameters of the laser cutting component according to various indexes such as cutting quality, speed, power and the like, so as to obtain the optimal cutting effect and quality. Therefore, the device can realize self-adaptive control of the cutting parameters of the laser cutting assembly by acquiring and processing the cutting parameters in real time, so that the cutting quality and the processing efficiency are improved, and the rejection rate and the processing time are reduced.
It will be appreciated that first, various actual data of the currently cut curved glass edge film is acquired by the monitoring system and transmitted to the control assembly. The data comprise data of a curved glass edge film (particularly, thickness, movement speed and the like of the curved glass edge film) and data of a laser cutting assembly (particularly, cutting focal length, focal depth and the like of the laser cutting assembly). And then, the control component adjusts the cutting parameters of the laser cutting component according to the measured actual data. The adjustment of the cutting parameters comprises focus adjustment, energy adjustment and speed adjustment.
Specifically, the control assembly can adjust the laser focus position in the laser cutting assembly in real time according to the actually measured thickness of the curved glass edge film so as to ensure that the laser focus position is matched with the curved glass edge film with different thickness.
Illustratively, when the thickness of the curved glass edge film is 0.2mm, the laser focal position needs to be adjusted to a position at a distance of 0.2mm from the surface of the curved glass edge film.
In addition, the control component can determine the number of cutting knives according to the thickness of the curved glass edge film, wherein the energy of the cutting knives is changed along with the change of the thickness of the curved glass edge film.
Illustratively, the thickness of the edge film of the curved glass is 0.2mm, and the curved glass edge film is cut in its entirety by 3 knives, wherein the first knife energy is 1w, and the second knife and third knife energies are 0.5w. In other words, the first knife requires higher energy to cut the curved glass edge film, while the second two knives require lower energy to complete the cut.
In addition, the control assembly adjusts the cutting speed (namely the movement speed of the curved glass 200) according to the actually measured thickness of the edge film of the curved glass and the inversely proportional calculation of the thickness and the speed, and finally, the curved glass 200 is just cut through without being damaged.
Illustratively, when the thickness of the bent-edge glass edge film is 0.2mm, the cutting speed needs to be adjusted to 20mm/s, and when the thickness of the bent-edge glass edge film is 0.3mm, the cutting speed needs to be adjusted to 13.3mm/s.
It should be noted that, in this embodiment, the control module controls the cutting speed through the PWM signal, that is, controls the PWM pulse width control speed to match the thickness of the corresponding curved glass edge film, so as to achieve the cutting effect required by the final customer.
It should be noted that, the above-mentioned step S500 and step S600 do not have a specific sequence relationship, and only one of the above-mentioned cases, step S500 and step S600 may be performed simultaneously or may be performed alternately, which is not limited by the present invention, and may be selected by those skilled in the art according to practical situations.

Various modifications and variations of the present invention will be apparent to those skilled in the art.
