[0041] Figure 4 A schematic flowchart of the film cutting method provided in the embodiments of this application;

[0042] Figure 5 This is a schematic diagram of the structure of the film cutting device provided in the embodiments of this application. Detailed Implementation

[0043] Please refer to the illustrations, where the same component symbols represent the same components. The principles of this application are illustrated by example in a suitable computing environment. The following description is based on the specific embodiments of this application illustrated, and should not be construed as limiting other specific embodiments not detailed herein.

[0044] Please see Figure 1 , Figure 1 This is a schematic diagram of a first structure of the film cutting system provided for implementation of this application. The film cutting system includes a film cutting device, a control device, and a target sensor. The control device is communicatively connected to both the film cutting device and the target sensor. The target sensor is used to collect shape boundary data of the device to be coated with film, and the film cutting device is used to create the film for the device to be coated with film.

[0045] As one embodiment, the control device can acquire the shape boundary data of the device to be covered with film, and generate target template data corresponding to the device to be covered with film based on the shape boundary data, so as to provide the target template data to the film cutting device, which is used to cut the film of the device to be covered with film based on the target template data.

[0046] In another embodiment, the control device can also acquire the shape boundary data of the device to be covered with film, and match the corresponding preset template data from the preset template database according to the shape boundary data. After matching the target template data corresponding to the shape boundary data, the target template data is provided to the film cutting device, which is used to cut the film of the device to be covered with film according to the target template data.

[0047] Furthermore, in Figure 1 Based on the provided film cutting system, a shelf can also be added. Please refer to [link / reference]. Figure 2 , Figure 2 This is a second structural schematic diagram of the film-cutting system provided for implementation of this application. The film-cutting system also includes a shelf on which a target sensor is mounted. The shelf also has a platform on which the target sensor is located. The platform is used to place the device to be coated.

[0048] In some embodiments, a trigger switch can be provided on the placement platform. After the device to be coated is placed on the platform, the target sensor can be automatically triggered to start, so as to collect the shape boundary data of the device to be coated. After the device to be coated is removed from the platform, the target sensor can be automatically triggered to turn off, thereby saving power consumption of the target sensor and ensuring its performance. Understandably, the trigger switch can be a weight sensor, pressure sensor, etc. Of course, the target sensor can also be controlled to start or stop via a physical button, or it can be controlled to start or stop via a control device. There are various specific implementation methods, which will not be detailed here.

[0049] The platform, serving as a base for placing the film-applied device, provides a stable and level surface. This ensures that the shape boundary data collected from the device is not inaccurate due to shaking or tilting. Furthermore, the platform's size and design may be optimized for the range of common film-applied devices to better accommodate various equipment and guarantee stable placement. Alternatively, a support device can be installed on the platform to accommodate the size requirements of different devices and maintain their stability.

[0050] For example, the device to be coated can be placed on a tray first, and then the tray can be placed on a shelf. This allows the background of the device to be coated to be changed by altering the color of the tray. For instance, if the device is transparent, and the tray is black or opaque, the device will have an opaque background, or the shelf will be opaque. If the tray is semi-transparent, the device will have a semi-transparent background, or the shelf will be semi-transparent. This allows for adjustable light transmittance of the shelf.

[0051] In some embodiments, the target sensor described above may include an infrared sensor. The infrared sensor senses the shape boundary of the device to be covered by emitting and receiving infrared light to generate shape boundary data, which includes the boundary segments and edge chamfers of the device. Taking a mobile phone as an example, the boundary segments include the lengths of the four sides of the phone, and the edge chamfers include the four rounded corners of the phone.

[0052] In this embodiment, the shelf can be black or opaque, or it can be completely opaque.

[0053] This application uses an infrared sensor, which does not require direct contact with the device to be covered. This avoids scratches and stains that may occur on the surface of the device during data collection, effectively protecting its original appearance. Furthermore, it can accurately perceive the shape and boundary details of the device, including not only the boundary lines and chamfered edges, but also the subtle contours and positions of components like the camera and earpiece, providing a reliable data foundation for producing highly adhesive screen protectors. Secondly, it can complete the acquisition of shape and boundary data of the device in a very short time, facilitating the rapid collection of shape and boundary data for a large number of different models of devices, thus improving the efficiency of mass production.

[0054] In some embodiments, the target sensor includes a camera, and a supplementary light strip is also provided on the shelf, with the target sensor, shelf, and supplementary light strip distributed sequentially from top to bottom. The activation or deactivation of the supplementary light strip can be linked to the camera, with both being triggered simultaneously. Of course, the activation or deactivation of the supplementary light strip can also be controlled independently.

[0055] For example, the fill light strip can be set with multiple brightness levels to allow for selection and adjustment of its light emission. Of course, the brightness of the fill light strip can also be adaptively adjusted according to the environmental conditions.

[0056] This embodiment of the application provides sufficient and suitable lighting conditions for the camera to acquire shape boundary data by setting a supplementary light strip below the platform. In situations with insufficient ambient light, the light emitted by the supplementary light strip can illuminate the surface and boundaries of the device to be coated, allowing the camera to capture the detailed features of the device more clearly, thereby improving the accuracy of shape boundary data acquisition. Especially for devices with fine textures or dark colors, good lighting can prevent data acquisition deviations or omissions due to poor lighting.

[0057] Furthermore, by flexibly adjusting the camera's shooting angle, it's possible to capture images from different sides and heights of the device to be coated. This allows for the acquisition of shape and boundary data from multiple perspectives, further refining the overall understanding of the device's shape and thus improving the completeness and accuracy of data collection.

[0058] In this embodiment, the shelf can be semi-transparent.

[0059] When a light source shines on the device to be coated, because the device itself is opaque, the light will create a noticeable bright area around it. The space occupied by the device itself will block the light, creating shadows around it. By collecting this data and analyzing and measuring these shadows, the camera can accurately determine the length, width, and radius (R) of the device to be coated.

[0060] This application utilizes the opaque nature of the device to be covered by the screen protector. By activating a supplementary light strip and using a camera to capture images of the device, the shape of the device can be clearly captured, and even the positions of the earpiece and camera. This avoids functional obstruction, thereby improving the overall accuracy of screen protector application and the user experience.

[0061] In some embodiments, the aforementioned shelf may be equipped with an infrared sensor, a camera, and a supplementary lighting strip simultaneously. Please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of a third structure of the film cutting system provided for the implementation of this application. When collecting the shape boundary data of the device to be coated, only the infrared sensor can be activated, or only the camera and the supplementary light strip can be activated.

[0062] Understandably, cameras and infrared sensors can be switched depending on the needs. For example, infrared sensors can be used for devices consisting of several flat surfaces and simple edges. For devices with curved surfaces, uneven structures, or combinations of irregular shapes, a combination of a camera and a supplementary lighting strip can be used. Furthermore, when the precision requirements for film application are not particularly high, and only the film needs to roughly cover the device surface with lower requirements for edge fit and the accuracy of pre-drilled holes, infrared sensors can be used. When high-precision shape boundary data is required, such as in the production of high-precision custom films, where various functional holes on the device (such as earpiece holes, camera holes, button holes, etc.) need to be accurately pre-drilled, and a tight fit between the film and the device surface must be ensured, especially for device surfaces with complex textures or intricate patterns, a camera is necessary. For instance, when it is necessary to quickly obtain the shape boundary data of the device to be filmed within a short time, such as in the initial shape judgment stage of a large number of devices on a film application production line, infrared sensors can be used. In scenarios involving the production of high-end custom films or where extremely high film quality is required, a combination of a camera and a supplementary lighting strip can be used.

[0063] For example, when acquiring shape boundary data of a new device to be coated with film for the first time, a combination of a camera and a supplementary light strip can be used to obtain accurate shape boundary data, thereby generating more precise target template data. For acquiring shape boundary data of various devices to be coated with film in batches, an infrared sensor can be used to quickly obtain various types of shape boundary data.

[0064] In some embodiments, the control device is further configured to: configure the target sensor to collect shape boundary data of the device to be coated; match the corresponding preset template data from the preset template database according to the shape boundary data; if there is target template data in the preset template database that matches the shape boundary data, then use the target template data to make the film for the device to be coated.

[0065] In some embodiments, the target sensor includes an infrared sensor; the control device is further configured to: activate the infrared sensor to acquire shape boundary data of the device to be coated, the shape boundary data including the boundary line segments and edge chamfers of the device to be coated.

[0066] In some embodiments, the target sensor includes a camera; the control device is further configured to: activate the fill light strip and the camera when the device to be coated is placed on a semi-transparent stand, and acquire shape boundary data of the device to be coated through the camera, the shape boundary data including the boundary line segments and edge chamfers of the device to be coated.

[0067] In some embodiments, the control device is further configured to: if there is no target template data matching the shape boundary data in the preset template database, generate new template data corresponding to the device to be coated based on the shape boundary data, so as to use the new template data to make the film for the device to be coated.

[0068] In some embodiments, the control device is further configured to: after generating new template data corresponding to the device to be coated based on shape boundary data, provide the new template data to the film cutting device to cut out the test film for the device to be coated; if the test film meets the film coating standard of the device to be coated, then use the new template data to make subsequent films for the device to be coated.

[0069] In some embodiments, the control device is further configured to: determine the shape deviation between the test film and the film standard if the test film does not conform to the film application standard of the film application device;

[0070] Adjust the new template data with the goal of reducing shape deviation, and return to execute the step of providing the new template data to the film cutting equipment to cut out the test film for the film to be applied, until the preset number of cuts is reached.

[0071] In some embodiments, the control device is further configured to: store new template data that conforms to the film application standard into a preset template database.

[0072] In some embodiments, the control device is also connected to a server, which stores a preset template database, and the control device maintains the preset template database.

[0073] In some embodiments, the control device further includes a control screen that can load and present preset template data from a preset template database. Users can maintain the preset template data through the control screen, such as modifying or deleting certain preset template data, and adding new template data.

[0074] For example, the control screen can also load an operation interface with size adjustment buttons, such as two directional buttons. Pressing the left button decreases the size, and pressing the right button increases the size. For instance, given the shape boundary data of a certain mobile phone model, which includes the phone's width and length, once the width is selected, the width value can be adjusted using the directional buttons. Of course, the width can also be changed by directly inputting a value; the specific implementation method is not limited here.

[0075] In addition, this application embodiment also provides a film cutting method, which can be executed by the control device described above. Of course, the control device and the film cutting device can also be integrated into one device, and the film cutting method provided in this application embodiment can be executed through this integrated device. The target sensor or shelf in the above-described film cutting system can be disposed on the film cutting device. The target sensor, film cutting device, and control device in the above-described film cutting system can also be integrated into one device, and the film cutting method provided in this application embodiment can be executed through this integrated device.

[0076] Please see Figure 4 , Figure 4 This is a schematic flowchart of a film cutting method provided in an embodiment of this application. The film cutting method may include:

[0077] In 101, a target sensor is configured to collect shape boundary data of the device to be coated.

[0078] In step 102, the corresponding preset template data is matched from the preset template database based on the shape boundary data.

[0079] In step 103, if a target template data matching the shape boundary data exists in the preset template database, the target template data will be used to create the film for the device to be coated.

[0080] Specifically, a pre-set template database is provided. When cutting the film for the device to be covered, the shape boundary data of the device to be covered can be collected first through a target sensor. Based on the shape boundary data, the corresponding pre-set template data can be matched from the pre-set template database. If a target template data matching the shape boundary data exists in the pre-set template database, the target template data can be directly called and provided to the film cutting device. The film cutting device can then cut the film for the device to be covered according to the target template data, so that the produced film fits the specific part of the device to be covered.

[0081] The method provided in this application embodiment eliminates the need for manual measurement of the shape boundary data of the device to be coated, as well as manual input or querying of such data. It enables rapid acquisition of the shape boundary data of the device and quick retrieval of corresponding target template data from a preset template database. This not only improves the efficiency of film cutting but also avoids human error, thereby increasing the accuracy of film cutting.

[0082] In some embodiments, if the target sensor is an infrared sensor, step 101 includes:

[0083] The infrared sensor is activated to collect the shape boundary data of the device to be coated with film. The shape boundary data includes the boundary line segments and edge chamfers of the device to be coated with film.

[0084] This embodiment of the application only uses an infrared sensor to collect the shape boundary data of the device to be coated. For details, please refer to the above-mentioned content, which will not be repeated here.

[0085] In some embodiments, if the target sensor is a camera, the shelf is provided with the target sensor, a semi-transparent shelf, and a supplementary light strip arranged sequentially from top to bottom. Step 101 includes:

[0086] With the device to be coated placed on a semi-transparent platform, the fill light strip and camera are activated. The camera collects the shape boundary data of the device to be coated, including the boundary line segments and edge chamfers of the device.

[0087] This embodiment of the application uses only a combination of a camera and a supplementary light strip to acquire the shape boundary data of the device to be coated. For details, please refer to the above-mentioned content, which will not be repeated here. The camera's shooting angle is adjustable, and the brightness of the supplementary light strip is also adjustable.

[0088] It is understood that the target sensor mentioned in the embodiments of this application is not limited to an infrared sensor or a camera, but may also be a laser sensor, an ultrasonic sensor, etc. It is understood that with technological advancements, the infrared sensor or camera mentioned in the embodiments of this application may be replaced by new sensors, but this will not affect the implementation of the overall concept of the embodiments of this application.

[0089] For example, to improve the accuracy of shape boundary data acquisition, the shape boundary data may include not only boundary line segments and edge chamfers, but also the outlines of the power connector, camera, earpiece, etc. of the device to be coated.

[0090] In some embodiments, after step 103, the film cutting method further includes:

[0091] 104. If no target template data matching the shape boundary data exists in the preset template database, a new template data corresponding to the device to be coated is generated based on the shape boundary data, so that the new template data can be used to make the coating for the device to be coated.

[0092] If the preset template database is stored in the control device, the control device can match the preset template data corresponding to the shape boundary data from the preset template database. If the preset template database is stored in the server, the server can match the preset template data corresponding to the shape boundary data from the preset template database.

[0093] If a preset template data corresponding to the shape boundary data can be matched, this preset template data is called the target template data. If no preset template data corresponding to the shape boundary data can be matched, the control device can output a matching failure message. This matching failure message can be output in text or sound format.

[0094] If no matching preset template data is found for the shape boundary data, it indicates that the target preset template data for the device to be coated does not exist in the preset template database. Therefore, new template data for the device to be coated can be generated based on the shape boundary data. The film cutting equipment can then produce a large number of films that fit specific parts of the device to be coated based on this new template data.

[0095] In some embodiments, step 104 includes:

[0096] 1041. After generating new template data corresponding to the device to be covered based on the shape boundary data, the new template data is provided to the film cutting device to cut out the test film for the device to be covered.

[0097] 1042. If the test film meets the film application standards of the device to be filmed, the new template data will be used to create the subsequent film application for the device to be filmed.

[0098] Understandably, new template data can be generated directly based on the shape and boundary data of the device to be coated, and this new template data can be directly entered into the preset template database for use in the production of the device to be coated. Alternatively, after generating new template data based on the shape and boundary data, the new template data can be verified and tested. Once the verification test is passed, the new template data that has passed the verification test can be entered into the preset template data for use in the production of the device to be coated.

[0099] For example, when performing verification tests on new template data, the new template data can be provided to the film cutting device for film cutting to cut out the test film for the device to be filmed. Then, the test film is applied to a specific part of the device to be filmed. By observing or monitoring the film application effect on the device to be filmed, the verification test can be evaluated.

[0100] For example, you can check if the film covers the specific area of ​​the device to be covered without any offset or misalignment. Then, carefully inspect the edges of the film for any rough edges. For instance, gently run your finger along the edge of the film to feel if it is smooth and flat. If there are rough edges, you will clearly feel that the edges are uneven, with small bumps or a rough texture. Next, focus on observing the film's fit on the curved parts of the device. View the film at the curved parts from different angles to check if the curve can be completely closed, that is, if the film has no gaps or overlaps at the edges of the curve. You can also use tools such as a magnifying glass to assist in observation and ensure the accuracy of the curve's fit. If the curve cannot be completely closed, you may see a small gap between the film and the surface of the device to be covered, or unnatural wrinkles or curling at the transition of the curve.

[0101] If observation reveals that the film does not completely cover a specific area of ​​the device to be covered, or that there is offset or misalignment, rough edges, or incomplete closure of the arc, it indicates that the tested film does not meet the film application standards for the device. If observation reveals that the film completely covers the specific area of ​​the device to be covered, without offset or misalignment, without rough edges, and with complete closure of the arc, it indicates that the tested film meets the film application standards for the device.

[0102] Of course, quality inspection equipment can also be used to intelligently inspect the appearance of the device after film application based on film application standards, in order to evaluate whether the tested film application meets the film application standards of the device. This quality inspection equipment can be integrated into the control equipment. The control equipment can acquire the film application data of the device through target sensors, and then perform film application quality analysis on the film application data. Based on the quality standards, it will output a quality inspection report, which will show whether the tested film application meets or does not meet the film application standards.

[0103] After testing that the film meets the film application standards of the device to be filmed, the new target data corresponding to the device to be filmed can be entered into the preset template database for use in the production of film application for the device to be filmed.

[0104] In some embodiments, after step 1041, the film cutting method further includes:

[0105] 1043. If the test film does not conform to the film application standard of the device to be filmed, then determine the shape deviation between the test film and the film application standard;

[0106] 1044. Adjust the new template data with the goal of reducing shape deviation, return to the step of providing the new template data to the film cutting equipment to cut out the test film for the film to be applied, until the preset number of cuts is reached.

[0107] When the test film does not meet the film application standards of the device to be filmed, the new template data can be adjusted based on the shape deviation between the film application standards and the test film. The adjusted new template data can cover the original new template data.

[0108] When adjusting the new template data, you can use the directional keys mentioned above to adjust the length or width values. The area that needs adjustment is the part where the test screen protector and the device to be covered cannot fully adhere. For example, if the test screen protector is shorter than the width of the phone, you can increase the width value in the new template data to make the adjusted width fit the width of the phone.

[0109] After the first adjustment of the new template data, the adjusted new template data can be provided to the film cutting equipment to cut out the second test film. Then, the second test film is applied to the film-to-be-applied equipment to determine whether the second test film meets the film-applied standards of the film-to-be-applied equipment. If the second test film meets the film-applied standards, the adjusted new template data is entered into the preset template database for use in the production of film-applied equipment.

[0110] If the second test film application does not meet the application standards of the equipment to be applied, the shape deviation between the second test film and the application standards can be determined, and a new template data can be adjusted based on this deviation. The adjusted template data is then provided to the film cutting equipment to cut out the third test film. This third test film is then applied to the equipment to be applied, and its compliance with the application standards is determined. This process is repeated until the latest test film meets the application standards. The new template data corresponding to the latest test film is then entered into a preset template database for use in the production of the film for the equipment to be applied.

[0111] For example, this application embodiment takes into account the film cutting efficiency and also sets a preset number of cuts. The preset number of cuts is consistent with the number of times the test film is cut to generate a test film. When the preset number of cuts is reached, even if the latest test film still does not meet the film application standard, the adjustment of the new template data for film cutting can be stopped, thereby finding the reason for the film cutting failure.

[0112] The preset number of cuts can be three. Of course, it can also be adaptively adjusted according to the accuracy of the target sensor. If the target sensor's acquisition accuracy is low, the preset number of cuts can be increased; if the target sensor's acquisition accuracy is high, the preset number of cuts can be decreased.

[0113] In some embodiments, the method further includes the following after step 104:

[0114] 105. Store the new template data that meets the film application standards into the preset template database.

[0115] In this embodiment, new template data conforming to the film application standard can be stored in a preset template database. Specific implementation details are as described in the above embodiments and will not be repeated here.

[0116] In summary, this application embodiment employs a method of acquiring shape boundary data of the device to be coated using a target sensor. Compared to traditional manual measurement of the device's dimensions, this effectively avoids human measurement errors and accurately obtains the actual shape boundary data of the device. Simultaneously, by constructing a preset template database, after acquiring the shape boundary data, corresponding preset template data can be matched within the database. If a matching target template exists, it is directly applied to the coating process. This solution offers several advantages: First, it efficiently generates new template data and quickly retrieves target data from the database to perform the coating cutting operation, significantly improving coating production efficiency and cutting accuracy. Second, it eliminates the need for manual measurement, input, or querying of the device's shape boundary data; it quickly acquires data and retrieves target template data, greatly improving cutting efficiency and effectively avoiding human error through automated processes, thereby significantly improving cutting accuracy and bringing more precise, efficient, and reliable technical improvements to the coating production process. Furthermore, this application embodiment fully considers cutting efficiency by specifically setting a preset number of cuts, which is the same as the number of times test coatings are cut. During the manufacturing process, the new template data is adjusted to minimize shape deviations. The process then returns to provide this new template data to the film-cutting equipment to cut the test film for the device to be covered. This cycle is repeated until the preset number of cuts is reached. This process improves film-cutting efficiency while further optimizing the fit between the film and the device to be covered. It maximizes the accuracy of film cutting and the quality of film application while ensuring cutting efficiency, making the entire film application process more scientific, efficient, and precise.
