[0021] When the local path segment is a conic curve, the planar coordinates of the endpoints of each discrete path segment are calculated sequentially, starting from one endpoint of the local path segment, based on the major axis, minor axis, focus, and the included angle formed by the local path segment, as well as the length of the discrete path segment in the discrete direction.

[0022] In some embodiments, before controlling the first polishing element to move along the first planar polishing path and perform polishing, and controlling the second polishing element to move along the second planar polishing path and perform polishing, the method further includes:

[0023] Obtain the thickness parameters of the display glass to be polished at the location of the designed path;

[0024] Based on the thickness parameter, a first lifting path and a second lifting path are generated; the heights of the first lifting path and the second lifting path are positively correlated with the thickness parameter, and at the same position on the design path, the height of the first lifting path is greater than the height of the second lifting path;

A first planar polishing path is obtained by fitting the first polishing coordinates, and a second planar polishing path is obtained by fitting the second polishing coordinates. The first polishing component is controlled to polish along the first planar polishing path, and finally, the second polishing component is controlled to polish along the second planar polishing path. Since the difference in coordinate values ​​and relative position between the first and second polishing coordinates in the discrete directions of the discrete path segments are constant, the first and second planar polishing paths are thus fitted, allowing for accurate configuration of the movement paths of the first and second polishing components. The planar line shapes of the first and second planar polishing paths accurately match the planar line shapes of the design path, ensuring that the first and second polishing components maintain accurate intervals during movement, thus improving the processing accuracy of the glass polishing equipment when polishing different types of display glass.

[0047] Glass polishing refers to the process of reducing the surface roughness of glass products through mechanical, chemical, or electrochemical actions to obtain a bright, smooth surface or rounded corners. Currently, various electronic products require display glass, such as mobile phones, LCD TVs, and automotive displays, all of which require polishing during processing. However, display glass comes in many varieties, each with different parameter requirements and process specifications. Different types of display glass require different polishing processes, and existing glass polishing equipment suffers from low polishing precision and a limited range of display glass types that can be processed when configured with these processes.

[0048] Based on this, embodiments of this application provide a display glass polishing method, apparatus, device, and storage medium, aiming to improve the processing accuracy of glass polishing equipment when polishing different types of display glass.

[0049] Please see Figure 1 , Figure 1 This is an optional flowchart of the display glass polishing method provided in the embodiments of this application. In some embodiments of this application, Figure 1 The method described below may include, but is not limited to, steps S101 to S105. Figure 1 These five steps will be explained in detail.

[0050] Step S101: Read the path design file containing the design path.

[0051] Understandably, the path design file stores the design path designed by the designer. The planar line shape of the design path matches the planar line shape of the polishing path of the display glass to be polished. The design path is input into the glass polishing equipment as the basis for generating the polishing path.

[0052] In this embodiment, the path design file is a DXF format graphic file.

[0053] In step S101, the glass polishing equipment reads the path design file, parses the path design file and obtains the design path in the path design file, so as to further process the design path.

[0054] Step S102: Discretize the design path to obtain multiple discrete path segments.

[0055] In step S102, the design path is discretized using image processing software. The required discretization precision is input, and the design path is discretized into multiple discrete path segments, so that the design path is transformed from a whole into a discrete graphic composed of multiple discrete path segments.

[0056] In some embodiments, step S102 specifically includes: discretizing the design path along the discretization direction according to a preset discretization precision to obtain multiple discrete path segments of the same length in the discretization direction. The discretization direction is parallel to the length direction of the design path.

[0057] Specifically, after obtaining the design path from the path design file, the discrete direction is determined based on the length direction of the design path, making the discrete direction parallel to the length direction of the design path. The discrete precision is set, and the design path is discretized along the discrete direction to discretize the design path into multiple discrete path segments. This transforms the design path from a whole into a discrete graphic composed of multiple discrete path segments, and the resulting discrete path segments have the same length in the discrete direction.

[0058] For example, the length of the design path is along the horizontal coordinate direction of the preset plane coordinate system in the path design file. The length direction of the design path is determined to be parallel to the horizontal coordinate direction of the preset plane coordinate system. That is, the design path is discretized along the horizontal coordinate direction of the preset plane coordinate system, and the length components of the resulting discrete path segments are the same in the horizontal coordinate direction of the preset plane coordinate system.

[0059] The formula for calculating the number of discrete path segments is:

[0060]

[0061] Where n is the number of discrete path segments, L is the length of the designed path in the discrete direction, and ω is the length of the discrete path segment in the discrete direction.

[0062] Step S103: Based on the shape of the design path and the length of the discrete path segments in discrete directions, generate multiple polishing coordinate pairs. Each polishing coordinate pair includes a first polishing coordinate and a second polishing coordinate. The first polishing coordinate is the planar coordinate of the endpoint of the discrete path segment, and the second polishing coordinate is the planar coordinate on the design path. The difference between the coordinate values ​​of the first and second polishing coordinates in the discrete directions of the discrete path segment and their relative positions are constant.

[0063] It is understandable that a first polishing coordinate and a second polishing coordinate constitute a polishing coordinate pair. Both the first and second polishing coordinates are planar coordinates on the design path. The first polishing coordinate is the planar coordinate of the endpoint of the discrete path segment, and the second polishing coordinate is the planar coordinate of the first polishing coordinate in the same polishing coordinate pair with a certain preset distance. In each polishing coordinate pair, the first and second polishing coordinates have a constant distance in the discrete direction of the discrete path segment, and the relative positions of the first and second polishing coordinates are constant. That is, the order of the first and second polishing coordinates in each polishing coordinate pair remains unchanged; it can be that the first polishing coordinate comes first and the second polishing coordinate comes second, or vice versa. For a polishing coordinate pair, after determining the first polishing coordinate, the corresponding second polishing coordinate can be determined according to the relative positional relationship between the first and second polishing coordinates.

[0064] In step S103, based on the shape of the line body of the design path, starting from the first endpoint of the first discrete path segment, the planar coordinates of the endpoints of each discrete path segment are calculated sequentially along the discrete direction of the discrete path segment to obtain each first polishing coordinate. Then, based on the relative positional relationship between the first polishing coordinate and the second polishing coordinate, the corresponding second polishing coordinate is calculated, thereby generating multiple polishing coordinate pairs.

[0065] like Figure 2As shown, in some embodiments, step S103 may specifically include, but is not limited to, steps S201 to S204, as described below. Figure 2 These four steps will be explained in detail.

[0066] Step S201: The design path is segmented to obtain several local path segments.

[0067] In step S201, the design path is segmented according to the local line shape of the design path to obtain several local path segments with a single line shape. For example, the local path segments can be straight lines, arcs and / or conic curves.

[0068] Step S202: Calculate the planar coordinates of the endpoints of each discrete path segment based on the shape of the local path segment and the length of the discrete path segment in the discrete direction.

[0069] Step S202 specifically includes:

[0070] When the local path segment is a straight line, the slope of the local path segment is calculated based on the planar coordinates of the endpoints of the local path segment. Based on the slope of the local path segment and the length of the discrete path segment in the discrete direction, the planar coordinates of the endpoints of each discrete path segment are calculated sequentially, starting from one endpoint of the local path segment.

[0071] When the local path segment is an arc, the plane coordinates of the endpoints of each discrete path segment are calculated sequentially, starting from one endpoint of the local path segment, based on the radius length of the local path segment, the plane coordinates of the center of the circle, and the length of the discrete path segment in the discrete direction.

[0072] When the local path segment is a conic section, the planar coordinates of the endpoints of each discrete path segment are calculated sequentially, starting from one endpoint of the local path segment, based on the major axis, minor axis, focus, and the included angle formed by the local path segment, as well as the length of the discrete path segment in the discrete direction.

[0073] When a local path segment is a straight line, the planar coordinates of the two endpoints of the local path segment are obtained from the path design file to calculate the slope of the local path segment. The formula for calculating the slope of a local path segment is:

[0074]

[0075] Where k is the slope of the local path segment, y1 is the ordinate of the first endpoint of the discrete path segment, y2 is the ordinate of the second endpoint of the discrete path segment, x1 is the abscissa of the first endpoint of the discrete path segment, and x2 is the abscissa of the second endpoint of the discrete path segment.

[0076] Based on the slope of the local path segment and the length of the discrete path segment in the discrete direction, the planar coordinates of the endpoints of each discrete path segment are calculated starting from the first endpoint of the local path segment. The formula for calculating the planar coordinates of the endpoints of the discrete path segment is as follows:

[0077]

[0078] x ai = (i-1)·ω,

[0079] Among them, y ai Let x be the ordinate value of the endpoint of the i-th discrete path segment. ai Let y be the x-coordinate of the endpoint of the i-th discrete path segment. a1 =y1,x a1 = x1, i∈[1,2,3,......,n], where n is the total number of endpoints of the discrete path segment.

[0080] When a local path segment is an arc, the radius and center coordinates of the local path segment are obtained from the path design file. Based on the radius, center coordinates, and lengths of the discrete path segments in discrete directions, the plane coordinates of the endpoints of each discrete path segment are calculated, starting from the first endpoint of the local path segment. The formula for calculating the plane coordinates of the endpoints of the discrete path segments is as follows:

[0081]

[0082] x ai = (i-1)·ω,

[0083] Where R is the radius of the local path segment, y0 is the ordinate of the center of the i-th discrete path segment, and x0 is the abscissa of the center of the i-th discrete path segment.

[0084] When a local path segment is a conic section, the major axis, minor axis, focus, and the included angle formed by the local path segment are obtained from the path design file to calculate the eccentricity of the local path segment. The formula for calculating the eccentricity of the local path segment is:

[0085]

[0086] Where e is the eccentricity, c is the focus, and a is the major axis;

[0087] The type of a local path segment is determined by its eccentricity. When 0 < e < 1, the local path segment is a local ellipse. The formula for calculating the planar coordinates of the endpoints of the discrete path segment is:

[0088]

[0089] When e > 1, the local path segment is a local hyperbola, and the formula for calculating the planar coordinates of the endpoints of the discrete path segment is:

[0090]

[0091] x ai = (i-1)·ω,

[0092] Where b is the minor axis and θ is the angle formed by the local path segment.

[0093] Step S203: Determine the first polishing coordinates based on the planar coordinates of the endpoints of the discrete path segments, and determine the second polishing coordinates based on the first polishing coordinates and the preset spacing parameters.

[0094] In step S203, the planar coordinates of the endpoints of the discrete path segments are used as the first polishing coordinates, and then the second polishing coordinates are calculated one by one according to the relative positional relationship between the first polishing coordinates and the second polishing coordinates in the discrete direction.

[0095] The formula for calculating the first polishing coordinate is:

[0096] y ai =y 1i ,

[0097] x ai =x 1i ,

[0098] Among them, y 1i Let x be the ordinate value of the i-th first polishing coordinate. 1i Let x be the x-coordinate value of the i-th first polishing coordinate.

[0099] When the local path segment is a straight line, the formula for calculating the second polishing coordinate is:

[0100]

[0101] When the local path segment is an arc, the formula for calculating the second polishing coordinate is:

[0102]

[0103] When the local path segment is a local ellipse, the formula for calculating the second polishing coordinate is:

[0104]

[0105] When the local path segment is a local hyperbola, the formula for calculating the second polishing coordinate is:

[0106]

[0107] Among them, y 2iLet x be the ordinate value of the i-th second polishing coordinate. 2i Let x be the x-coordinate value of the i-th second polishing coordinate.

[0108] Step S204: Construct a polishing coordinate pair using the first polishing coordinate and the second polishing coordinate.

[0109] In step S204, the first polishing coordinates and the second polishing coordinates calculated using the first polishing coordinates are matched to construct multiple polishing coordinate pairs.

[0110] Step S104: Perform path fitting processing based on each first polishing coordinate to obtain a first planar polishing path; perform path fitting processing based on each second polishing coordinate to obtain a second planar polishing path.

[0111] In step S104, a path is fitted based on the calculated first polishing coordinates to obtain a first planar polishing path, and a path is fitted based on the calculated second polishing coordinates to obtain a second planar polishing path. The specific process of fitting the path can be to connect two adjacent first polishing coordinates (two adjacent second polishing coordinates) to obtain the path to be fitted.

[0112] Step S105: Control the first polishing part to polish along the first plane polishing path, and control the second polishing part to polish along the second plane polishing path.

[0113] In step S105, the first polishing component and the second polishing component are used simultaneously to polish the display glass to be polished. The first polishing component is controlled to move along the polishing path of the first plane so that the first polishing component passes through each first polishing coordinate. The second polishing component is controlled to move along the polishing path of the second plane so that the second polishing component passes through each second polishing coordinate. At the same time, the first polishing component and the second polishing component polish during the movement.

[0114] It is understandable that the first and second planar polishing paths obtained by fitting are basically overlapping. The difference is that the first planar polishing path completely overlaps with the design path, while the second planar polishing path is indented or shifted back by one end. By fitting the first and second planar polishing paths respectively, the movement paths of the first and second polished parts can be accurately configured. The planar line shapes of the first and second planar polishing paths accurately match the planar line shapes of the design path, and the first and second polished parts can maintain an accurate interval during movement.

[0115] When the first polished part moves along the polishing path of the first plane, it passes through each of the first polishing coordinates. When the second polished part moves along the polishing path of the second plane, it passes through each of the second polishing coordinates.

[0116] In some embodiments, step S105 specifically includes:

[0117] Obtain polishing mode settings information. Polishing modes include overall polishing and partial polishing.

[0118] According to the polishing mode settings, the system controls the first polishing component to reciprocate along the first plane polishing path and the second polishing component to reciprocate along the second plane polishing path, and / or controls the first polishing component to reciprocate within a local area of ​​the first plane polishing path and the second polishing component to reciprocate within a local area of ​​the second plane polishing path. The polishing mode settings can be configured to perform overall polishing followed by local polishing, overall polishing only, or local polishing only. Overall polishing involves controlling the first polishing component to reciprocate along the first plane polishing path and the second polishing component to reciprocate along the second plane polishing path. Local polishing involves controlling the first polishing component to reciprocate within a local area of ​​the first plane polishing path and the second polishing component to reciprocate within a local area of ​​the second plane polishing path. During both overall and local polishing, the first polishing component must pass through the corresponding first polishing coordinate, and the second polishing component must pass through the corresponding second polishing coordinate to ensure consistent reciprocating polishing paths.

[0119] like Figure 3 As shown, in some embodiments, steps S301 to S303 are included, but not limited to, before step S105. The following is a detailed description... Figure 3 These three steps will be explained in detail.

[0120] Step S301: Obtain the thickness parameters of the display glass to be polished at the designed path position.

[0121] Step S302: Generate a first lifting path and a second lifting path based on the thickness parameter. The heights of both the first and second lifting paths are positively correlated with the thickness parameter; at the same position on the designed path, the height of the first lifting path is greater than the height of the second lifting path.

[0122] Step S303: Associate and match the first lifting path and the first plane polishing path, and associate and match the second lifting path and the second plane polishing path.

[0123] In steps S301 to S303, the thickness parameters of the display glass to be polished at the design path position are obtained from the path design file or other parameters. Then, the heights of the first polishing part and the second polishing part when moving along the first lifting path are set according to the thickness parameters. The heights of the first lifting path and the second lifting path are positively correlated with the thickness parameters. That is, the thicker the position to be polished, the higher the heights of the first and second polishing parts are set, and the thinner the position to be polished, the lower the heights of the first and second polishing parts are set. According to the set height parameters, the first lifting path and the second lifting path are generated. Then, the first lifting path and the first planar polishing path are associated and matched, and the second lifting path and the second planar polishing path are associated and matched, so as to polish the display glass to be polished with a relatively stable polishing intensity.

[0124] It should be noted that at the same position on the design path, the height of the first lifting path is greater than the height of the second lifting path. That is, when the first polishing part and the second polishing part are at the same position, the height of the first polishing part is greater than the height of the second polishing part. The first polishing part is polished with lower intensity first, and then the second polishing part is polished with higher intensity, thereby improving polishing efficiency.

[0125] In some embodiments, the heights of the first polishing component and the second polishing component can be controlled separately by a PLC controller, and the rotational speeds of the first polishing component and the second polishing component can be different.

[0126] Please see Figure 4 This application also provides a display glass polishing apparatus, which can implement the above-described display glass polishing method. The apparatus includes:

[0127] The first module 401 is used to read a path design file containing the design path;

[0128] The second module 402 is used to discretize the design path to obtain multiple discrete path segments.

[0129] The third module 403 is used to generate multiple polishing coordinate pairs based on the shape of the line body of the design path and the length of the discrete path segment in the discrete direction. The polishing coordinate pair includes a first polishing coordinate and a second polishing coordinate. The first polishing coordinate is the planar coordinate of the endpoint of the discrete path segment, and the second polishing coordinate is the planar coordinate on the design path. The difference between the coordinate values ​​of the first polishing coordinate and the second polishing coordinate in the discrete direction of the discrete path segment and their relative positions are constant.

[0130] The fourth module 404 is used to perform path fitting processing based on each first polishing coordinate to obtain a first planar polishing path, and to perform path fitting processing based on each second polishing coordinate to obtain a second planar polishing path.

[0131] The fifth module 405 is used to control the first polishing part to polish along the first plane polishing path and to control the second polishing part to polish along the second plane polishing path.

[0132] The specific implementation of this display glass polishing device is basically the same as the specific embodiment of the display glass polishing method described above, and will not be repeated here.

[0141] This application also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described display glass polishing method.

[0142] The display glass polishing method, apparatus, device, and storage medium provided in this application embodiment discretize the design path in the path design file into multiple discrete path segments. Based on the line shape of the design path and the length of the discrete path segments in the discrete directions, multiple polishing coordinates and multiple second polishing coordinates are generated. A first planar polishing path is obtained by fitting the first polishing coordinates, and a second planar polishing path is obtained by fitting the second polishing coordinates. The first polishing component is controlled to polish along the first planar polishing path, and finally, the second polishing component is controlled to polish along the second planar polishing path. Since the difference in coordinate values ​​and relative position between the first and second polishing coordinates in the discrete directions of the discrete path segments are constant, the first and second planar polishing paths are thus fitted, allowing for accurate configuration of the movement paths of the first and second polishing components. The planar line shapes of the first and second planar polishing paths accurately match the planar line shapes of the design path, ensuring accurate spacing between the first and second polishing components during movement. This improves the processing accuracy of the glass polishing equipment when polishing different types of display glass.
