[0043] Please refer to the drawings, where the same component symbols represent the same components. The principle of the present application is illustrated by implementing it in an appropriate computing environment. The following description is based on the illustrated specific embodiments of the present application, which should not be considered as limiting other specific embodiments of the present application that are not described in detail herein.

[0044] See also Figure 1 , Figure 1 The first structural diagram of the film cutting system provided for the implementation of this application. The film cutting system includes a film cutting device, a control device and a target sensor, the control device is respectively connected to the film cutting device and the target sensor for communication, the target sensor is used to collect the shape boundary data of the device to be filmed, and the film cutting device is used to make the film of the device to be filmed.

[0045] As an embodiment, the control device can obtain the shape boundary data of the device to be film-pasted, and generate target template data corresponding to the device to be film-pasted 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 film-pasted based on the target template data.

[0046] As another embodiment, the control device can also obtain the shape boundary data of the device to be film-pasted, and match the corresponding preset template data from the preset template database according to the shape boundary data, so as to provide the target template data corresponding to the shape boundary data to the film cutting device after matching, and the film cutting device is used to cut the film of the device to be film-pasted according to the target template data.

[0047] Further, in Figure 1 In addition to the provided film cutting system, a shelf can also be added. Figure 2 , Figure 2 A second structural schematic diagram of the film cutting system provided for the implementation of the present application. The film cutting system also includes a rack, on which the target sensor is arranged, and the rack is also provided with a table, on which the target sensor is located. The table is used to place the device to be film-applied.

[0048] In some embodiments, a trigger switch can be set on the storage table. After the device to be film-applied is placed on the storage table, the target sensor can be automatically triggered to start up to collect the shape boundary data of the device to be film-applied. After the device to be film-applied is removed from the storage table, the target sensor can be automatically triggered to shut down, thereby saving power for the target sensor and ensuring the performance of the target sensor. It can be understood that the trigger switch can be a weight sensor, a pressure sensor, etc. Of course, the target sensor can also be started or shut down by a physical button, or by a control device. There are many specific implementation methods, which will not be described in detail here.

[0049] As a platform for placing the equipment to be filmed, the storage table can provide a stable and horizontal placement surface. It can ensure that in the process of collecting the shape boundary data of the equipment to be filmed, the collected shape boundary data will not be inaccurate due to factors such as shaking and tilting. In addition, the size and design of the storage table may also be optimized according to the size range of common equipment to be filmed, so as to better adapt to various types of equipment and ensure the stability of the equipment placement. Alternatively, a holding device can be set on the storage table to adapt to the size requirements of various equipment to be filmed and maintain the placement stability of the equipment to be filmed.

[0050] For example, the device to be film-coated can be placed on a tray first, and then the tray can be placed on the storage table. In this way, the background of the device to be film-coated can be changed by changing the color of the tray. For example, if the device to be film-coated is transparent, when the tray is black or opaque, the device to be film-coated is an opaque background, or the storage table is in an opaque state. When the tray is translucent, the device to be film-coated is a semi-translucent background, or the storage table is in a semi-translucent state. In this way, the light transmittance of the storage table can be adjusted.

[0051] In some embodiments, the target sensor may include an infrared sensor. The infrared sensor senses the shape boundary of the device to be filmed by emitting and receiving infrared rays to generate shape boundary data, which includes boundary line segments and edge chamfers of the device to be filmed. Taking a mobile phone as an example of a device to be filmed, the boundary line segments include the lengths of the four sides of the mobile phone, and the edge chamfers include the four R angles of the mobile phone.

[0052] In this embodiment, the storage table may be black or opaque, or may be lightproof.

[0053] The embodiment of the present application uses an infrared sensor and does not need to make direct contact with the device to be filmed. It avoids possible scratches and stains on the surface of the device to be filmed during the collection process, and can well protect the original appearance of the device to be filmed. In addition, the shape boundary details of the device to be filmed can be more accurately perceived. For example, not only the boundary segments and edge chamfers of the mobile phone can be perceived, but also the subtle contours and positions of the camera and earpiece of the mobile phone can be perceived, providing a reliable data basis for the subsequent production of highly fitted films. Secondly, it can also complete the collection of shape boundary data of the device to be filmed in a very short time, which is conducive to the rapid collection of shape boundary data of a large number of different models of devices to be filmed, which is conducive to the mass production of films and improves the efficiency of film production.

[0054] In some embodiments, the target sensor includes a camera, and a fill light bar is also provided on the shelf, and the target sensor, the shelf, and the fill light bar are arranged in order from top to bottom. The start or shut down of the fill light bar can be associated with the camera, and both can be triggered to start or shut down at the same time. Of course, the start or shut down of the fill light bar can also be controlled separately.

[0055] Exemplarily, the fill light bar can be provided with a plurality of gears for selection to adjust its luminous brightness. Of course, the brightness of the fill light bar can also be adaptively adjusted according to the environmental conditions in which it is located.

[0056] The embodiment of the present application can provide sufficient and appropriate lighting conditions for the camera to collect shape boundary data by setting a supplementary light bar under the storage table. In some cases where the ambient light is insufficient, the light emitted by the supplementary light bar can illuminate the surface and boundary of the device to be filmed, so that the camera can capture the detailed features of the device more clearly, thereby improving the accuracy of shape boundary data collection. Especially for some devices with subtle textures or dark colors on the surface, good lighting can avoid deviations or omissions in data collection due to poor light.

[0057] In addition, by flexibly adjusting the camera's shooting angle, it is possible to shoot the film-applying device from different sides and at different heights. The device's shape boundary data can be obtained from multiple perspectives, further improving the overall understanding of the device's shape, thereby improving the integrity and accuracy of data collection.

[0058] The storage table in this embodiment may be in a semi-translucent state.

[0059] When a light source shines on the device to be coated, since the device to be coated itself is not light-transmissive, the light will form an obvious bright area around it, and the space occupied by the device to be coated will block the light, thus forming a shadow part around it. The camera collects this data, analyzes and measures these shadow parts, and can more accurately obtain the length, width and R angle of the device to be coated.

[0060] The embodiment of the present application utilizes the opaque property of the device to be filmed, and can capture the image of the device to be filmed by turning on the fill light bar and the camera, so as to clearly capture the shape of the device to be filmed, and even the earpiece and camera position of the device to be filmed, etc., thereby avoiding the problem of function obstruction, thereby improving the accuracy of film production and user experience as a whole.

[0061] In some embodiments, the above-mentioned shelf can be provided with an infrared sensor, a camera and a fill light bar at the same time. Figure 3 , Figure 3 A third structural diagram of the film cutting system provided for the implementation of this application: When collecting the shape boundary data of the device to be filmed, only the infrared sensor can be activated, or only the camera and the fill light bar can be activated.

[0062] It is understandable that the camera and the infrared sensor can be switched and used according to the needs. For example, for the equipment to be filmed that consists of several planes and simple edges, an infrared sensor can be used. For the equipment to be filmed that has a curved surface, a concave-convex structure, and a combination of multiple irregular shapes, a combination of a camera and a fill light bar can be used. For another example, when the accuracy requirements for the film are not particularly high, and the film only needs to roughly cover the surface of the device, and the requirements for the fit of the edge and the accuracy of the reserved holes are low, an infrared sensor can be used. When high-precision shape boundary data is required, such as making high-precision customized films, it is necessary to accurately reserve various functional holes on the device (such as earpiece holes, camera holes, button holes, etc.), and to ensure that the film is closely fitted to the surface of the device, especially for the surface of the device with complex textures or fine patterns, a camera is required. For another example, when the shape boundary data of the equipment to be filmed needs to be obtained quickly in a short time, such as the link of preliminary shape judgment of a large number of devices on the film production line, an infrared sensor can be used. In the scene of making high-end customized films or extremely high requirements for film quality, a combination of cameras and fill light bars can be used.

[0063] For example, for the initial collection of shape boundary data of a new device to be coated, a combination of a camera and a fill light bar can be used to obtain accurate shape boundary data, thereby generating more accurate target template data. For the need to collect a batch of shape boundary data of various devices to be coated, an infrared sensor can be used to quickly obtain various shape boundary data.

[0064] In some embodiments, the control device is also used to: configure a target sensor to collect shape boundary data of the device to be filmed; match corresponding preset template data from a preset template database based on the shape boundary data; if there is target template data matching the shape boundary data in the preset template database, the target template data is used to make the film for the device to be filmed.

[0065] In some embodiments, the target sensor includes an infrared sensor; the control device is further used to: start the infrared sensor to collect shape boundary data of the device to be film-mounted, and the shape boundary data includes boundary line segments and edge chamfers of the device to be film-mounted.

[0066] In some embodiments, the target sensor includes a camera; the control device is also used to: when the device to be filmed is placed on a translucent storage table, start the fill light bar and the camera, and collect shape boundary data of the device to be filmed through the camera, wherein the shape boundary data includes boundary line segments and edge chamfers of the device to be filmed.

[0067] In some embodiments, the control device is also used to: if there is no target template data matching the shape boundary data in the preset template database, then generate new template data corresponding to the device to be filmed according to the shape boundary data, so as to use the new template data to make the film for the device to be filmed.

[0068] In some embodiments, the control device is also used to: after generating new template data corresponding to the device to be film-affixed based on the shape boundary data, provide the new template data to the film cutting device to cut out a test film for the device to be film-affixed; if the test film meets the film-affixing standard of the device to be film-affixed, use the new template data to make subsequent films for the device to be film-affixed.

[0069] In some embodiments, the control device is further used to: if the test film does not meet the film sticking standard of the device to be filmed, determine the shape deviation between the test film and the film sticking standard;

[0070] The new template data is adjusted with the goal of reducing the shape deviation, and the step of providing the new template data to the film cutting device to cut out the test film of the film-sticking device is returned to be executed until the preset number of cutting times is reached.

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

[0072] In some embodiments, the control device is further connected to a server for communication. The server is used to store a preset template database, and the control device is used to maintain the preset template database.

[0073] In some embodiments, the control device also includes a control screen, which can load and present preset template data in the preset template database. The user can maintain the preset template data through the control screen, such as modifying and deleting certain preset template data, and adding new template data.

[0074] Exemplarily, the control screen can also load an operation interface, on which there are size adjustment buttons, such as two direction buttons, where the left button can be used to reduce the size, and the right button can be used to increase the size. For example, for the shape boundary data of a certain model of mobile phone, the shape boundary data includes the width and length of the mobile phone. After the width is selected, the value of the width can be adjusted by the direction buttons. Of course, the width can also be changed by directly entering a value, and the specific implementation method is not limited here.

[0075] In addition, the embodiment of the present application also provides a film cutting method, which can be performed by the control device as above. Of course, the control device and the film cutting device can also be integrated into one device, and the film cutting method provided by the embodiment of the present application can be performed by the integrated device. The target sensor or the rack in the above-mentioned film cutting system can be set on the film cutting device. The target sensor, the film cutting device and the control device in the above-mentioned film cutting system can also be integrated into one device, and the film cutting method provided by the embodiment of the present application can be performed by the integrated device.

[0076] See also Figure 4 , Figure 4 A schematic diagram of a process of a film cutting method provided in an embodiment of the present application. The process of the film cutting method may include:

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

[0078] In 102, corresponding preset template data is matched from a preset template database according to the shape boundary data.

[0079] In 103, if there is target template data matching the shape boundary data in the preset template database, the target template data is used to make the film for the device to be filmed.

[0080] Specifically, a preset template database is pre-set. When it is necessary to cut the film of the device to be film-pasted, the shape boundary data of the device to be film-pasted can be first collected through the target sensor, so as to match the corresponding preset template data from the preset template database according to the shape boundary data. When there is target template data matching the shape boundary data in the preset template database, the target template data can be directly called to provide the target template data to the film cutting device, and the film cutting device can cut the film of the device to be film-pasted according to the target template data, so that the produced film fits the specific part of the device to be film-cut.

[0081] The method provided by the embodiment of the present application does not require manual measurement of the shape boundary data of the device to be filmed, nor does it require manual input or query of the shape boundary data of the device to be filmed. The shape boundary data of the device to be filmed can be quickly obtained, and the corresponding target template data can also be quickly called from the preset template database. This not only improves the efficiency of film cutting, but also avoids manual errors and improves 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 started to collect shape boundary data of the device to be film-mounted, wherein the shape boundary data includes boundary line segments and edge chamfers of the device to be film-mounted.

[0084] The embodiment of the present application only collects the shape boundary data of the device to be filmed by the infrared sensor. The specific content can be referred 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 a target sensor, a semi-transparent storage table and a fill light bar which are sequentially distributed from top to bottom. Step 101 includes:

[0086] When the device to be film-coated is placed on a translucent storage table, the fill light bar and the camera are started, and shape boundary data of the device to be film-coated is collected through the camera. The shape boundary data includes boundary line segments and edge chamfers of the device to be film-coated.

[0087] The embodiment of the present application only collects the shape boundary data of the device to be filmed by combining a camera and a fill light bar. The specific content can be referred to the above-mentioned content, and will not be repeated here. The shooting angle of the camera is adjustable, and the brightness of the fill light bar is also adjustable.

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

[0089] For example, to improve the accuracy of shape boundary data collection, the shape boundary data includes not only boundary line segments and edge chamfers, but also contours of the power connector, camera, earpiece, etc. of the device to be film-coated.

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

[0091] 104. If there is no target template data matching the shape boundary data in the preset template database, new template data corresponding to the device to be film-mounted is generated according to the shape boundary data, so as to use the new template data to make film for the device to be film-mounted.

[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 the preset template data corresponding to the shape boundary data can be matched, the preset template data is called the target template data. If the preset template data corresponding to the shape boundary data cannot be matched, the control device can output a matching failure message. The matching failure message can be output in text or sound.

[0094] When the preset template data corresponding to the shape boundary data cannot be matched, it means that the target preset template data corresponding to the device to be film-applied does not exist in the preset template database. Therefore, new template data corresponding to the device to be film-applied can be generated according to the shape boundary data. The film cutting device can produce a large number of films that fit the specific parts of the device to be film-applied based on the new template data.

[0095] In some embodiments, step 104 includes:

[0096] 1041. After generating new template data corresponding to the device to be film-mounted according to the shape boundary data, providing the new template data to a film cutting device to cut out a test film for the device to be film-mounted;

[0097] 1042. If the test film meets the film-sticking standard of the device to be film-sticked, the new template data is used to make subsequent films for the device to be film-sticked.

[0098] It is understandable that new template data can be directly generated according to the shape boundary data of the device to be film-applied, so that the new template data can be directly entered into the preset template database for use in producing the film-applied device to be film-applied. It is also possible that after generating the new template data according to the shape boundary data, the new template data can be firstly verified and tested, and after 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 producing the film-applied device to be film-applied.

[0099] For example, when performing a verification test on new template data, the new template data can first be provided to the film cutting device for film cutting to cut out a test film for the device to be film-affixed, and then the test film can be affixed to a specific part of the device to be film-affixed, and the film-affixing effect of the device to be film-affixed can be observed to evaluate whether the test film has passed the verification test.

[0100] For example, you can observe whether the film covers the specific part of the device to be filmed and there is no offset or misalignment. Then carefully check the edge of the film to see if there are burrs. For example, gently touch the edge of the film with your fingers to feel whether the edge is smooth and flat. If there are burrs, you will obviously feel that the edge is uneven, with small bumps or roughness. Then focus on observing the film fitting at the arc part of the device to be filmed. View the film at the arc from different angles to check whether the arc can be completely closed, that is, there is no gap or overlap at the edge of the arc. You can also use tools such as a magnifying glass to assist in observation to ensure the accuracy of the arc fitting. If the arc cannot be completely closed, you may see a small gap between the film and the surface of the device to be filmed, or unnatural wrinkles or warping at the transition of the arc.

[0101] If it is found through observation that the film does not completely cover the specific part of the device to be filmed, or there is a deviation or misalignment, or there are burrs, or the arc is not completely closed, it means that the test film does not meet the film-pasting standards for the device to be filmed. If it is found through observation that the film completely covers the specific part of the device to be filmed, and there is no deviation or misalignment, no burrs, and the arc is completely closed, it means that the test film meets the film-pasting standards for the device to be filmed.

[0102] Of course, quality inspection equipment can also be used to intelligently inspect the appearance of the film-applying equipment based on the film-applying standards to evaluate whether the test film meets the film-applying standards of the film-applying equipment. The quality inspection equipment can be integrated on the control device, which can obtain the post-film-applying data of the film-applying equipment through the target sensor, and then perform film-applying quality analysis on the post-film-applying data, and output a quality inspection report based on the quality standards. The quality inspection report can present the result that the test film meets the film-applying standards or the test film does not meet the film-applying standards.

[0103] After the test film meets the film-sticking standard of the equipment to be film-sticked, new target data corresponding to the equipment to be film-sticked can be entered into a preset template database for use in producing the film-sticking of the equipment to be film-sticked.

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

[0105] 1043. If the test film does not meet the film sticking standard of the device to be film stuck, determine the shape deviation between the test film and the film sticking standard;

[0106] 1044. Adjust the new template data with the goal of reducing the shape deviation, and return to execute the step of providing the new template data to the film cutting device to cut out the test film for the film sticking device until the preset number of cutting times is reached.

[0107] When the test film does not meet the film sticking standard of the device to be film stuck, the new template data can be adjusted based on the shape deviation between the film sticking standard and the test film, and the adjusted new template data can overwrite the new template data before adjustment.

[0108] When adjusting the new template data, you can use the direction keys mentioned above to adjust the length or width value in the new template data. The range that needs to be adjusted is the part where the test film and the device to be filmed cannot be completely fitted. For example, when the test film is shorter than the width of the mobile phone, you can increase the width value in the new template data so that the adjusted width fits the width of the mobile phone.

[0109] After adjusting the new template data for the first time, the new template data after the first adjustment can be provided to the film cutting equipment to cut out the second test film, and then the second test film is affixed to the equipment to be film-pasted to determine whether the second test film meets the film-pasting standards of the equipment to be film-pasted; if the second test film meets the film-pasting standards, the new template data after the first adjustment will be entered into the preset template database for use in producing the film for the equipment to be film-pasted.

[0110] If the second test film does not meet the film sticking standard of the device to be filmed, the shape deviation between the second test film and the film sticking standard can be further determined, and the new template data can be adjusted for the second time based on the shape deviation. The new template data after the second adjustment is then provided to the film cutting device to cut out the third test film, and then the third test film is attached to the device to be filmed to determine whether the third test film meets the film sticking standard of the device to be filmed. This process is repeated until the latest test film meets the film sticking standard. The new template data corresponding to the latest test film is entered into the preset template database for use in producing films for the device to be filmed.

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

[0112] Of course, it can also be adjusted adaptively according to the accuracy of the target sensor. When the acquisition accuracy of the target sensor is low, the preset number of cutting times can be increased, and when the acquisition accuracy of the target sensor is high, the preset number of cutting times can be reduced.

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

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

[0115] In this embodiment, the new template data that meets the film sticking standard can be stored in the preset template database. Specific implementation method refers to the contents mentioned in the above embodiment, which will not be repeated here.

[0116] In summary, the embodiment of the present application adopts a method of configuring a target sensor to collect the shape boundary data of the equipment to be filmed. Compared with the traditional manual measurement of the size of the equipment to be filmed, it effectively avoids the manual measurement error and accurately obtains the actual shape boundary data of the equipment to be filmed. At the same time, by constructing a preset template database, after obtaining the shape boundary data, the corresponding preset template data can be matched in the library. If there is a matching target template data, it is directly applied to the film production. This solution has many advantages: first, it can efficiently generate new template data and quickly call the target data from the library to perform the film cutting operation, which significantly improves the efficiency of film production and the accuracy of film cutting; second, there is no need to manually measure, input or query the shape boundary data of the equipment to be filmed, and the data can be quickly obtained and the target template data can be called, which not only greatly improves the efficiency of film cutting, but also effectively avoids manual operation errors by relying on the automated process, thereby effectively improving the accuracy of film cutting, and bringing more accurate, efficient and reliable technical improvements to the film production process. In addition, the embodiment of the present application fully considers the efficiency of film cutting, and specially sets a preset number of cutting times, and the preset number of cutting times is the same as the number of times the test film is generated by cutting. During the production process, the new template data is adjusted with the goal of reducing the shape deviation, and the new template data is returned to the step of providing the film cutting device to cut out the test film for the device to be filmed, and this cycle is repeated until the preset number of cuts is reached. Through this process, while improving the film cutting efficiency, the matching degree between the film and the device to be filmed can be further optimized. On the basis of ensuring the film cutting efficiency, the accuracy of film cutting and the quality of filming can be maximized, making the entire film production process more scientific, efficient and accurate.
