Technical Field
[0001] This invention relates to the field of electronic paper module manufacturing, and in particular to a method and system for applying an easy-tear protective film. Background Technology
[0002] Electronic paper modules are now widely used in supermarket price tags, e-books, mobile phones, and other electronic devices. Easy-tear stickers are used to easily remove the protective film from LCD, LCM, and TP panels, saving time and leaving no residue. Currently, the manual process for applying PS protective film easy-tear stickers in electronic paper module production is as follows: manually picking up material from the tray, applying adhesive with an aluminum strip, applying the easy-tear sticker, pre-peeling the lead, and placing the product back on the tray.
[0003] Currently, the application of PS protective film easy-tear labels in electronic paper module production is entirely manual, requiring a certain number of personnel per line per shift. With increasing market demand, the shortcomings of this manual process are becoming increasingly apparent: the aluminum strip application process demands precise control over force and position; excessive force during manual operation can cause glass edge chipping and cracking, and misalignment can easily scrape off the IC protective silicone. Furthermore, manual application of the easy-tear labels is prone to misalignment, significantly impacting product yield and leading to automated equipment failures during customer module assembly. In addition, the PS protective film easy-tear label application process requires highly skilled personnel, lengthy training periods, and frequent personnel turnover, which also significantly affects product yield and the consistency of easy-tear label application. Summary of the Invention
[0004] This invention provides a method and system for applying easy-tear protective film stickers to solve the above-mentioned technical problems. It can overcome the shortcomings and deficiencies of the existing manual application of easy-tear protective film stickers and effectively improve the product yield of easy-tear protective film stickers.
[0005] To address the aforementioned technical problems, this invention provides a method for applying an easy-to-tear protective film, applicable to a display module. The display module has a protective film attached to its upper surface. The application method includes:
[0006] The current display module is moved to the preset adhesive scraping position, and the residual adhesive of the current display module is scraped off at the preset position based on the preset adhesive scraping pressure to obtain the adhesive-scraped display module;
[0007] Move the pre-applied adhesive display module to the preset labeling position and attach the easy-tear protective film sticker to the preset area of the protective film to complete the application of the easy-tear protective film sticker.
[0008] The beneficial effects of this invention are as follows:
[0009] Compared to existing manual application of protective film stickers, which is difficult to control in terms of adhesive pressure and position, and prone to misalignment, affecting product yield and causing automated equipment failures during customer module assembly, this invention addresses the issue by moving the current display module to a preset adhesive scraping position and scraping off residual adhesive at that position based on preset adhesive pressure. This results in an adhesive-covered display module, which is then moved to a preset labeling position where the protective film sticker is applied to the preset area. This allows for precise control of adhesive pressure and position to prevent glass chipping and cracking, and precise control of the sticker's application position to avoid misalignment. This automated and precise application of the protective film sticker overcomes the shortcomings of existing manual application methods, effectively improving the product yield of the applied protective film sticker.
[0010] As a preferred embodiment, after moving the current display module to the preset adhesive scraping position and scraping off the residual adhesive from the current display module at the preset position based on the preset adhesive scraping pressure to obtain an adhesive-scraped display module, the method further includes:
[0011] Place the pre-applied adhesive display module at the preset starting position, and rotate the pre-applied adhesive display module horizontally by a preset angle, thereby pre-peeling the protective film from the upper surface of the pre-applied adhesive display module at a preset angle to obtain the pre-started display module;
[0012] Move the already mounted display module to the preset labeling position and attach the easy-tear protective film sticker to the preset area of the protective film to complete the application of the easy-tear protective film sticker.
[0013] The protective film is tightly attached to the upper surface of the display module. This preferred solution achieves the pre-starting and pre-tearing operation of the protective film by pre-tearing it from the upper surface of the already peeled-off display module at a preset angle. This ensures that users can easily remove the protective film by using the easy-tear sticker, making it more convenient to peel off the protective film from the upper surface of the display module and improving the user experience.
[0014] This preferred solution involves rotating the already coated display module horizontally by a preset angle before pre-peeling the protective film from the upper surface of the display module at a preset angle. By setting the preset angle, the pre-lifting and pre-peeling operations of the protective film in different directions can be met.
[0015] As a preferred embodiment, the method for applying the easy-tear protective film further includes:
[0016] If the protective film is not successfully peeled off from the pre-exposed adhesive display module at the preset angle, a failure signal is generated.
[0017] In response to the failure signal, the glued display module is treated as a defective product and discarded.
[0018] If the protective film cannot be successfully peeled off the pre-set angle from the top surface of the already peeled-off display module, the peeled-off display module has failed to be peeled off. This indicates that the protective film is too tightly adhered to the top surface of the already peeled-off display module, making it difficult for users to remove the protective film from the top surface of the display module later using the easy-tear protective film sticker, resulting in a poor user experience. This preferred solution treats peeled-off display modules that fail to peel off as unqualified products and discards them, ensuring that users receive display modules where the protective film can be easily peeled off, allowing users to easily and conveniently remove the protective film from the top surface of the display module using the easy-tear protective film sticker, thus improving the user experience.
[0019] As a preferred embodiment, the step of moving the current display module to the preset adhesive scraping position includes: moving the current display module to the preset adhesive scraping position and performing position correction on the current display module;
[0020] The step of moving the glued display module to the preset labeling position includes: moving the glued display module to the preset labeling position and correcting the position of the glued display module;
[0021] The step of placing the glued display module into the preset starting position includes: placing the glued display module into the preset starting position and performing position correction on the glued display module;
[0022] The step of moving the raised display module to the preset labeling position includes: moving the raised display module to the preset labeling position and correcting the position of the raised display module.
[0023] This preferred solution performs positional calibration on the display module after it has been moved to the appropriate processing position. This helps reduce positional deviations caused by moving the display module to the appropriate processing position, ensuring product consistency in subsequent processing. When the product is placed in the correct position, subsequent processing steps are easier to perform, avoiding operational problems caused by positional deviations, ensuring product quality, and positional calibration can avoid repetitive work and errors caused by improper positioning, reducing rework and correction time, thereby improving overall work efficiency.
[0024] As a preferred embodiment, before moving the current display module to the preset adhesive scraping position, the method further includes: cleaning the surface of the initial display module to obtain the current display module.
[0025] This preferred solution cleans the surface of the display module before moving it to the preset adhesive application position. This removes dust, grease, stains, and other impurities, resulting in a smoother and cleaner surface. This allows the adhesive on the easy-tear protective film to better contact the display module surface, enhancing adhesion and ensuring the film adheres more firmly to the module. This ensures that subsequent protective films are tightly bonded to the display module surface, avoiding issues such as bubbles and peeling edges. Consequently, it improves the adhesion and aesthetics, and extends the lifespan of the protective film.
[0026] Accordingly, in order to solve the above-mentioned technical problems, the present invention also provides an easy-tear protective film application system for display module, wherein a protective film is applied to the upper surface of the display module, and the application system includes: a control device, a scraping mechanism, an application mechanism and a conveying mechanism.
[0027] The adhesive scraping mechanism is used to scrape off residual adhesive from the current display module;
[0028] The attachment mechanism is used to attach the easy-tear sticker of the protective film to a preset area of the protective film.
[0029] The transport mechanism is used to transport the display module to a preset processing position;
[0030] The control device is used to control the transport mechanism to transport the current display module to the preset adhesive scraping position, and to control the adhesive scraping mechanism to scrape off the residual adhesive of the current display module at the preset position based on the preset adhesive scraping pressure, so as to obtain an adhesive-scraped display module; to control the transport mechanism to transport the adhesive-scraped display module to the preset labeling position, and to control the labeling mechanism to apply the easy-tear protective film sticker to the preset area of the protective film, thus completing the application of the easy-tear protective film sticker.
[0031] Compared to existing manual application of protective film stickers, which is difficult to control in terms of adhesive pressure and position, and prone to misalignment, affecting product yield and causing automated equipment to fail to peel off the film during customer module assembly, this invention provides a protective film sticker application system consisting of a control device, adhesive scraping mechanism, application mechanism, and transport mechanism. This system transports the current display module to a preset adhesive scraping position and scrapes off residual adhesive at the preset position based on preset adhesive pressure, resulting in an adhesive-covered display module. The adhesive-covered display module is then transported to a preset labeling position, and the protective film sticker is applied to the preset area of the protective film. This system allows for precise control of adhesive scraping pressure and position to prevent glass chipping and cracking, and precise control of the protective film sticker application position to prevent misalignment. This achieves automated and precise application of the protective film sticker, overcoming the shortcomings and deficiencies of existing manual application methods and effectively improving the product yield of the applied protective film sticker.
[0032] As a preferred embodiment, the protective film easy-tear application system further includes a lifting mechanism; the lifting mechanism is used to horizontally rotate the already coated display module by a preset angle, thereby pre-tearing the protective film from the upper surface of the already coated display module at a preset angle.
[0033] The control device is also used to control the transport mechanism to place the peeled-off display module to a preset starting position, and to control the starting mechanism to rotate the peeled-off display module horizontally by a preset angle, thereby controlling the starting mechanism to pre-tear the protective film from the upper surface of the peeled-off display module at a preset angle to obtain the peeled-off display module; to control the transport mechanism to transport the peeled-off display module to a preset labeling position, and to control the application mechanism to apply the easy-tear protective film sticker to the preset area of the protective film, thus completing the application of the easy-tear protective film sticker.
[0034] The protective film is tightly attached to the upper surface of the display module. This preferred solution controls the lifting mechanism to pre-tear the protective film from the upper surface of the already adhesive-coated display module at a preset angle, realizing the pre-lifting and pre-tearing operation of the protective film. This ensures that users can easily remove the protective film by using the easy-tear sticker, making it more convenient to tear the protective film off the upper surface of the display module and improving the user experience.
[0035] In this preferred embodiment, before the protective film is pre-torn from the upper surface of the coated display module at a preset angle, the lifting mechanism is controlled to rotate the coated display module horizontally by a preset angle. By setting the preset angle, the pre-lifting and pre-tearing operations of the protective film in different directions can be met.
[0036] As a preferred embodiment, the protective film easy-tear sticker application system further includes an angle detection mechanism; the angle detection mechanism is used to generate a lifting failure signal when the lifting mechanism fails to successfully peel the protective film off the upper surface of the squeezed-adhesive display module at a preset angle.
[0037] The control device is also used to, in response to a failure signal, classify the glued display module as a defective product and control the conveyor mechanism to move the glued display module to the defective product unloading conveyor.
[0038] If the protective film cannot be successfully peeled off the pre-set angle from the top surface of the already coated display module, the peeling process fails. This indicates that the protective film is too tightly adhered to the top surface of the display module, making it difficult for the user to remove it using the easy-tear sticker, resulting in a poor user experience. This preferred solution treats peeling-off display modules as defective products and transfers them to the defective product unloading conveyor belt. This ensures that users receive display modules with easily removable protective films, allowing them to easily and conveniently remove the protective film from the top surface of the display module using the easy-tear sticker, thus improving the user experience.
[0039] As a preferred embodiment, the protective film easy-tear sticker application system further includes a position correction mechanism; the position correction mechanism is used to correct the position of the display module after the transport mechanism places the display module into the preset processing position.
[0040] The control device is also used to control the position correction mechanism to correct the position of the display module after the control conveying mechanism places the display module into the preset processing position.
[0041] This preferred solution, after the control and handling mechanism moves the display module to the corresponding processing position, also performs position correction on the control and position correction mechanism of the display module. This helps reduce positional deviations caused by moving the display module to the corresponding processing position, ensuring product consistency in subsequent processing. When the product is placed in the correct position, subsequent processing steps are easier to perform, avoiding operational problems caused by positional deviations, ensuring product quality, and position correction can avoid repetitive work and errors caused by improper positioning, reducing rework and correction time, thereby improving overall work efficiency.
[0042] As a preferred embodiment, the protective film easy-tear sticker application system further includes a cleaning mechanism; the cleaning mechanism is used to clean the surface of the initial display module.
[0043] The control device is also used to control the cleaning mechanism to clean the surface of the initial display module before the control conveying mechanism moves the current display module to the preset adhesive scraping position, so as to obtain the current display module.
[0044] This preferred solution, before controlling the transport mechanism to move the display module to the preset adhesive application position, also controls the cleaning mechanism to clean the surface of the display module. This removes dust, grease, stains, and other impurities, resulting in a smoother and cleaner surface. This allows the adhesive on the easy-tear protective film to better contact the display module surface, enhancing adhesion and ensuring the easy-tear protective film is more firmly attached to the module. This ensures that subsequent applied easy-tear protective films adhere tightly to the display module surface, avoiding issues such as bubbles and peeling edges, thereby improving the adhesion effect and aesthetics, and extending the service life of the easy-tear protective film.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0049] Currently, the application of PS protective film easy-tear labels in electronic paper module production is entirely manual, requiring a certain number of personnel per line per shift. With increasing market demand, the shortcomings of this manual process are becoming increasingly apparent: the aluminum strip application process demands precise control over force and position; excessive force during manual operation can cause glass edge chipping and cracking, and misalignment can easily scrape off the IC protective silicone. Furthermore, manual application of the easy-tear labels is prone to misalignment, significantly impacting product yield and leading to automated equipment failures during customer module assembly. In addition, the PS protective film easy-tear label application process requires highly skilled personnel, lengthy training periods, and frequent personnel turnover, which also significantly affects product yield and the consistency of easy-tear label application.
[0050] Example 1
[0051] To address the aforementioned technical problems, this invention provides a method and system for applying easy-tear protective film stickers, which overcomes the shortcomings and deficiencies of existing manual application of easy-tear protective film stickers and effectively improves the product yield of the applied easy-tear protective film stickers.
[0052] Please refer to Figure 1 This is a flowchart illustrating one embodiment of an easy-tear protective film application method provided by the present invention.
[0053] The aforementioned method for applying an easy-to-tear protective film is used in display modules, where a protective film is applied to the upper surface of the display module. For example... Figure 1 As shown, the method for applying the easy-tear protective film includes steps 101 to 102, specifically:
[0054] Step 101: Move the current display module to the preset adhesive scraping position, and scrape off the residual adhesive of the current display module at the preset position based on the preset adhesive scraping pressure to obtain the adhesive-scraped display module;
[0055] Step 102: Move the pre-applied adhesive display module to the preset labeling position and attach the easy-tear protective film sticker to the preset area of the protective film to complete the application of the easy-tear protective film sticker.
[0056] Furthermore, after moving the current display module to the preset adhesive scraping position and scraping off the residual adhesive from the current display module at the preset position based on the preset adhesive scraping pressure to obtain an adhesive-scraped display module, the process further includes:
[0057] Place the pre-applied adhesive display module at the preset starting position, and rotate the pre-applied adhesive display module horizontally by a preset angle, thereby pre-peeling the protective film from the upper surface of the pre-applied adhesive display module at a preset angle to obtain the pre-started display module;
[0058] Move the already mounted display module to the preset labeling position and attach the easy-tear protective film sticker to the preset area of the protective film to complete the application of the easy-tear protective film sticker.
[0059] The protective film is tightly attached to the upper surface of the display module. This invention achieves the pre-starting and pre-tearing operation of the protective film by pre-tearing it from the upper surface of the already coated display module at a preset angle. This ensures that users can easily remove the protective film by using the easy-tear sticker, making it more convenient to tear the protective film off the upper surface of the display module and improving the user experience.
[0060] Before pre-tearing the protective film from the upper surface of the coated display module at a preset angle, the present invention also rotates the coated display module horizontally clockwise or counterclockwise by a preset angle. By setting the preset angle, the pre-lifting and pre-tearing operations of the protective film in different directions can be met.
[0061] In this embodiment, the preset angle can be set to 45 degrees.
[0062] Furthermore, the method for applying the protective film easy-tear sticker further includes:
[0063] If the protective film is not successfully peeled off from the pre-exposed adhesive display module at the preset angle, a failure signal is generated.
[0064] In response to the failure signal, the glued display module is treated as a defective product and discarded.
[0065] In this embodiment, the angle between the protective film and the upper surface of the peeled-off display module can be detected by optical fiber to determine whether the protective film has been successfully peeled off from the upper surface of the peeled-off display module at a preset angle. When the optical fiber senses that the angle between the protective film and the upper surface of the peeled-off display module reaches or exceeds a certain threshold, it will output a corresponding signal. At this time, it is determined that the protective film and the upper surface of the peeled-off display module are at a certain angle, that is, the protective film has been successfully peeled off from the upper surface of the peeled-off display module at a preset angle, and the peeling is successful. When the optical fiber does not detect that the protective film and the upper surface of the peeled-off display module are at a certain angle, a peeling failure signal is generated.
[0066] If the protective film cannot be successfully peeled off the pre-set angle from the top surface of the already coated display module, the peeling process fails. This indicates that the protective film is too tightly adhered to the top surface of the display module, making it difficult for the user to remove it using the easy-tear sticker, resulting in a poor user experience. This invention treats peeling-off display modules that fail to peel off as defective products and discards them, ensuring that users receive display modules where the protective film can be easily peeled off. This allows users to easily and conveniently remove the protective film from the top surface of the display module using the easy-tear sticker, improving the user experience.
[0067] Furthermore, the step of moving the current display module to the preset adhesive scraping position includes: moving the current display module to the preset adhesive scraping position and performing position correction on the current display module;
[0068] The step of moving the glued display module to the preset labeling position includes: moving the glued display module to the preset labeling position and correcting the position of the glued display module;
[0069] The step of placing the glued display module into the preset starting position includes: placing the glued display module into the preset starting position and performing position correction on the glued display module;
[0070] The step of moving the raised display module to the preset labeling position includes: moving the raised display module to the preset labeling position and correcting the position of the raised display module.
[0071] In this embodiment, the position correction process is as follows: obtain the overlapping area between the current position of the display module and the preset correction position; obtain movement data or movement path based on the overlapping area, wherein the movement data includes rotation angle, movement direction and movement distance; move the display module according to the movement data or movement path and update the current position of the display module until the current position of the display module completely overlaps with the preset correction position, thereby completing the position correction.
[0072] After moving the display module to the corresponding processing position, this invention also performs position correction on the display module, which helps to reduce positional deviations caused by moving the display module to the corresponding processing position, ensuring the consistency of the product in subsequent processing. When the product is placed in the correct position, subsequent processing steps are easier to perform, avoiding operational problems caused by positional deviations, ensuring product quality, and position correction can avoid repetitive work and errors caused by improper positioning, reducing rework and correction time, thereby improving overall work efficiency.
[0073] Furthermore, the step of moving the current display module to the preset adhesive application position includes: moving the adhesive-coated display module to the preset labeling position, performing positional correction on the adhesive-coated display module, and then performing vacuum adsorption on the adhesive-coated display module after correction. In this embodiment, after moving the display module to the corresponding processing position, the display module is positionally corrected, and then vacuum adsorbed. Vacuum adsorption ensures that the display module will not move or vibrate during processing, reducing processing errors caused by movement or vibration, and improving processing accuracy and stability. Furthermore, for some fragile or surface-sensitive products, such as electronic paper modules made of glass, traditional clamping methods may cause damage. Vacuum adsorption is a non-contact fixing method. In this embodiment, vacuum adsorption tightly adsorbs the display module to the preset processing position, avoiding mechanical damage or contamination to the product surface.
[0074] Furthermore, before moving the current display module to the preset adhesive scraping position, the process also includes: cleaning the surface of the initial display module to obtain the current display module.
[0075] Before moving the display module to the preset adhesive application position, this invention cleans the surface of the display module to remove dust, grease, stains, and other impurities. The cleaned surface of the display module is smoother and cleaner, which helps the adhesive on the easy-tear protective film to better contact the surface of the display module, enhancing adhesion and making the easy-tear protective film adhere more firmly to the module. This ensures that the subsequent applied easy-tear protective film can adhere tightly to the surface of the display module, avoiding problems such as bubbles and peeling edges, thereby improving the adhesion effect and aesthetics, and extending the service life of the easy-tear protective film.
[0076] Accordingly, in order to solve the above-mentioned technical problems, the present invention also provides an easy-tear protective film application system for display module, wherein a protective film is applied to the upper surface of the display module, and the application system includes: a control device, a scraping mechanism, an application mechanism and a conveying mechanism.
[0077] The adhesive scraping mechanism is used to scrape off residual adhesive from the current display module;
[0078] The attachment mechanism is used to attach the easy-tear sticker of the protective film to a preset area of the protective film.
[0079] The transport mechanism is used to transport the display module to a preset processing position;
[0080] The control device is used to control the transport mechanism to transport the current display module to the preset adhesive scraping position, and to control the adhesive scraping mechanism to scrape off the residual adhesive of the current display module at the preset position based on the preset adhesive scraping pressure, so as to obtain an adhesive-scraped display module; to control the transport mechanism to transport the adhesive-scraped display module to the preset labeling position, and to control the labeling mechanism to apply the easy-tear protective film sticker to the preset area of the protective film, thus completing the application of the easy-tear protective film sticker.
[0081] In this embodiment, the handling mechanism includes several handling arms.
[0082] Furthermore, the protective film easy-tear application system also includes a lifting mechanism; the lifting mechanism is used to horizontally rotate the already coated display module by a preset angle, thereby pre-tearing the protective film from the upper surface of the already coated display module at a preset angle.
[0083] The control device is also used to control the transport mechanism to place the peeled-off display module to a preset starting position, and to control the starting mechanism to rotate the peeled-off display module horizontally by a preset angle, thereby controlling the starting mechanism to pre-tear the protective film from the upper surface of the peeled-off display module at a preset angle to obtain the peeled-off display module; to control the transport mechanism to transport the peeled-off display module to a preset labeling position, and to control the application mechanism to apply the easy-tear protective film sticker to the preset area of the protective film, thus completing the application of the easy-tear protective film sticker.
[0084] In this embodiment, the preset processing position includes a preset adhesive scraping position, a preset labeling position, and a preset starting position.
[0085] The protective film is tightly attached to the upper surface of the display module. This invention controls the lifting mechanism to pre-tear the protective film from the upper surface of the already adhesive-coated display module at a preset angle, realizing the pre-lifting and pre-tearing operation of the protective film. This ensures that users can easily remove the protective film by using the easy-tear sticker, making it more convenient to tear the protective film from the upper surface of the display module and improving the user experience.
[0086] Before the protective film is pre-torn from the upper surface of the coated display module at a preset angle, the present invention also controls the lifting mechanism to rotate the coated display module horizontally clockwise or counterclockwise by a preset angle. By setting the preset angle, the pre-lifting and pre-tearing operations of the protective film in different directions can be met.
[0087] In this embodiment, the lifting mechanism includes a lifting robot and a lifting wheel. Under the control of the control device, the lifting robot aligns the lifting wheel with a corner of the protective film, ensuring that the edge of the lifting wheel is tightly attached to the protective film. The lifting robot applies a preset force to the lifting wheel, causing the lifting wheel to gradually cut into the gap between the protective film and the display module. After the lifting wheel successfully cuts into the gap, it slowly pulls the lifting wheel upward or to one side at a preset speed, causing the protective film to be torn off the display module at a certain angle.
[0088] In this embodiment, the adhesive scraping mechanism further includes: an adhesive scraping head control component and an adhesive scraping head; the adhesive scraping head control component controls the movement of the adhesive scraping head under the control of the control device, so that the adhesive scraping head scrapes off the residual adhesive of the current display module at a preset position based on a preset adhesive scraping pressure.
[0089] In this embodiment, the scraper head control assembly includes an X-axis moving module, a Y-axis moving module, and a Z-axis moving module; the X-axis moving module enables the scraper head to move in the X direction, the Y-axis moving module enables the scraper head to move in the Y direction, and the Z-axis moving module enables the scraper head to move in the Z direction.
[0090] In this embodiment, the pressure of the adhesive scraping can be monitored by a pressure sensor, and the data collected by the pressure sensor can be fed back to the control device so that the control device can adjust the adhesive scraping pressure according to the data collected by the pressure sensor.
[0091] In this embodiment, the control device uses machine vision algorithms or sensor technology to locate the residual adhesive area on the display module. Based on the residual adhesive area, it controls the X-axis moving module, the Y-axis moving module, and the Z-axis moving module to contact the residual adhesive area and move on the residual adhesive, thereby scraping the residual adhesive from the surface of the display module. After scraping, the control device controls the cleaning mechanism to use cleaning tools and cleaning agents to clean the surface of the display module, ensuring that there is no residual adhesive or traces left by the scraper head.
[0092] In this embodiment, the labeling mechanism further includes: a label feeding assembly, a drive motor, and a labeling robot.
[0093] The label feeding component is used to move the easy-tear protective film sticker to a preset label feeding position;
[0094] The drive motor controls the movement of the attaching robot under the control of the control device, so that the attaching robot can obtain the easy-tear sticker of the protective film at the preset label feeding position and attach the easy-tear sticker to the preset area of the protective film.
[0095] Specifically, the attachment robot includes an attachment robotic arm and an end effector;
[0096] Driven by a drive motor, the application robot arm moves the end effector to a preset label feeding position to obtain the easy-tear protective film sticker. Then, under the control of the drive motor, the application robot arm continues to move the end effector above the preset area of the protective film, thereby controlling the end effector to apply the easy-tear sticker to the preset area of the protective film, completing the application of the easy-tear protective film sticker.
[0097] In this embodiment, the drive motor is used to drive the attaching robot to move on the X-axis, Y-axis and Z-axis and drive the attaching robot to rotate on the rotating axis, so as to meet the requirements of easy-to-peel protective film attachment in different directions of the display module.
[0098] In this embodiment, the end effector is a suction cup or a gripper.
[0099] In this embodiment, the label feeding component peels off the protective film and delivers it to a preset label feeding position. The delivery position is consistent each time, ensuring that the labeling robot can obtain the protective film and peel off the label consistently.
[0100] Furthermore, the protective film easy-tear adhesive application system also includes several vacuum adsorption components, used to tightly adsorb the display module onto the preset processing position using negative pressure. This ensures that the display module does not move or vibrate during processing, reducing processing errors caused by movement or vibration, and improving processing accuracy and stability. Moreover, for some fragile or surface-sensitive products, such as electronic paper modules made of glass, traditional clamping methods may cause damage. Vacuum adsorption is a non-contact fixing method. In this embodiment, the vacuum adsorption components tightly adsorb the display module onto the preset processing position, avoiding mechanical damage or contamination to the product surface.
[0101] Furthermore, the protective film easy-tear adhesive application system also includes an angle detection mechanism; the angle detection mechanism is used to generate a lifting failure signal when the lifting mechanism fails to successfully peel the protective film from the upper surface of the scraped adhesive display module at a preset angle.
[0102] The control device is also used to, in response to a failure signal, classify the glued display module as a defective product and control the conveyor mechanism to move the glued display module to the defective product unloading conveyor.
[0103] If the protective film cannot be successfully peeled off the pre-set angle from the top surface of the already coated display module, the peeling process fails. This indicates that the protective film is too tightly adhered to the top surface of the display module, making it difficult for the user to remove it using the easy-tear sticker, resulting in a poor user experience. This invention treats peeling-off display modules that fail to peel off as defective products and transfers them to the defective product unloading conveyor belt. This ensures that users receive display modules where the protective film can be easily peeled off, allowing for simple and convenient removal of the protective film from the top surface of the display module using the easy-tear sticker, thus improving the user experience.
[0104] In this embodiment, the angle between the protective film and the upper surface of the peeled-off display module can be detected by optical fiber to determine whether the protective film has been successfully peeled off from the upper surface of the peeled-off display module at a preset angle. When the optical fiber senses that the angle between the protective film and the upper surface of the peeled-off display module reaches or exceeds a certain threshold, it will output a corresponding signal. At this time, it is determined that the protective film and the upper surface of the peeled-off display module are at a certain angle, that is, the protective film has been successfully peeled off from the upper surface of the peeled-off display module at a preset angle, and the peeling is successful. When the optical fiber does not detect that the protective film and the upper surface of the peeled-off display module are at a certain angle, a peeling failure signal is generated.
[0105] Furthermore, the protective film easy-tear sticker application system also includes a position correction mechanism; the position correction mechanism is used to correct the position of the display module after the transport mechanism places the display module into the preset processing position.
[0106] The control device is also used to control the position correction mechanism to correct the position of the display module after the control conveying mechanism places the display module into the preset processing position.
[0107] After the control and handling mechanism moves the display module to the corresponding processing position, the present invention also performs position correction on the control and position correction mechanism of the display module. This helps to reduce the positional deviation caused by moving the display module to the corresponding processing position, ensuring the consistency of the product in subsequent processing. When the product is placed in the correct position, subsequent processing steps are easier to perform, avoiding operational problems caused by positional deviation, ensuring product quality, and position correction can avoid repetitive work and errors caused by improper positioning, reducing rework and correction time, thereby improving overall work efficiency.
[0108] In this embodiment, the position correction mechanism is a cylinder, which realizes the position correction of the display module in the X and Y directions. The position correction process is as follows: under the control of the control device, the cylinder is in contact with the side of the display module to obtain the overlapping area between the current position of the display module and the preset correction position. Based on the overlapping area, the movement data or movement path is obtained. The movement data includes rotation angle, movement direction and movement distance. The cylinder is controlled to move according to the movement data or movement path, thereby driving the display module to move and update the current position of the display module until the current position of the display module is completely overlapped with the preset correction position, and the position correction is completed.
[0109] Furthermore, the protective film easy-tear adhesive application system also includes a cleaning mechanism; the cleaning mechanism is used to clean the surface of the initial display module.
[0110] The control device is also used to control the cleaning mechanism to clean the surface of the initial display module before the control conveying mechanism moves the current display module to the preset adhesive scraping position, so as to obtain the current display module.
[0111] Furthermore, the cleaning mechanism includes a rotating robotic arm and a cleaning robotic arm. The rotating robotic arm flips the initial display module so that the cleaning robotic arm can wipe the surface of the initial display module with a lint-free cloth and alcohol.
[0112] Before the control transport mechanism moves the display module to the preset adhesive application position, this invention also controls the cleaning mechanism to clean the surface of the display module. This removes dust, grease, stains, and other impurities, resulting in a smoother and cleaner surface. This allows the adhesive on the easy-tear protective film to better contact the display module surface, enhancing adhesion and ensuring the easy-tear protective film adheres more firmly to the module. This ensures that subsequent applied easy-tear protective films adhere tightly to the display module surface, avoiding problems such as bubbles and curling edges, thereby improving the adhesion effect and aesthetics, and extending the service life of the easy-tear protective film.
[0113] Please refer to the following. Figure 2 ,for Figure 2 This invention provides a schematic diagram of an embodiment of an easy-tear protective film application system.
[0114] like Figure 2 As shown, the protective film easy-tear sticker application system includes: a control device, a scraping mechanism 1, a lifting mechanism 2, an application mechanism 3, and a transport mechanism 4.
[0115] The adhesive scraping mechanism 1 is used to scrape off the residual adhesive from the current display module;
[0116] The lifting mechanism 2 is used to rotate the glued display module horizontally by a preset angle, thereby pre-tearing the protective film from the upper surface of the glued display module at a preset angle.
[0117] The attachment mechanism 3 is used to attach the easy-tear sticker of the protective film to the preset area of the protective film.
[0118] The transport mechanism 4 is used to transport the display module to a preset processing position;
[0119] The control device is used to control the glue scraping mechanism 1, the foot lifting mechanism 2, the attaching mechanism 3, and the handling mechanism 4 to perform corresponding processing operations.
[0120] In this embodiment, the handling mechanism 4 includes a plurality of handling arms 41.
[0121] In this embodiment, the protective film easy-tear sticker application system further includes a cleaning mechanism; the cleaning mechanism is used to clean the surface of the initial display module.
[0122] like Figure 2 As shown, the protective film easy-tear adhesive application system further includes: a loading platform 5 and a unloading platform 6; the loading platform 5 is used to convey and place several current display modules so that the conveying mechanism 4 can move the current display modules to the preset adhesive scraping position 11; the unloading platform 6 is used to place and convey several already attached display modules.
[0123] Figure 2The workflow of the protective film easy-tear sticker application system is as follows: Each current display module, after being cleaned by the cleaning mechanism, is placed on the loading platform 5. Under the control of the control device, the transport arm 41 transports the current display module on the loading platform 5 to the preset adhesive scraping position 11. The position correction mechanism corrects the position of the current display module. After correction, the vacuum adsorption component adsorbs and fixes the current display module. The adhesive scraping mechanism 1 scrapes off the residual adhesive of the current display module at the preset position based on the preset adhesive scraping pressure, resulting in an adhesive-scraped display module. After the adhesive scraping is completed, the transport arm 41 places the adhesive-scraped display module to the preset starting position 21. The position correction mechanism corrects the position of the adhesive-scraped display module. After correction, the vacuum adsorption component... The adhesive-coated display module is adsorbed and fixed. The lifting mechanism 2 rotates the adhesive-coated display module horizontally by a preset angle. Then, the lifting mechanism 2 peels off the protective film from the upper surface of the adhesive-coated display module at a preset angle to obtain the lifted display module. The adhesive-coated display module that fails to be lifted is transported to the unqualified product unloading belt by the transport arm 41. After the lifting is completed, the transport arm 41 transports the lifted display module to the preset labeling position 31. The position correction mechanism corrects the position of the lifted display module. After correction, the vacuum adsorption component adsorbs and fixes the lifted display module. Then, the attaching mechanism 3 attaches the protective film easy-tear sticker to the preset area of the protective film to complete the attachment of the protective film easy-tear sticker and obtain the attached display module.
[0124]
[0125] In existing manual application of protective film easy-tear stickers, incomplete application often results in the film not being able to be peeled off, leading to failure of automated equipment in the display module assembly process. Furthermore, manual application of protective film easy-tear stickers is characterized by poor application accuracy and inconsistent positioning. As shown in the table above, compared with existing manual labeling production methods, the application method and system for applying protective film easy-tear stickers proposed in this invention significantly improves the product yield, application efficiency, and product capacity, while also reducing labor costs.
[0126] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:
[0127] Compared to existing manual application of protective film stickers, which is difficult to control in terms of adhesive pressure and position, and prone to misalignment, affecting product yield and causing automated equipment failures during customer module assembly, this invention addresses the issue by moving the current display module to a preset adhesive scraping position and scraping off residual adhesive at that position based on preset adhesive pressure. This results in an adhesive-covered display module, which is then moved to a preset labeling position where the protective film sticker is applied to the preset area. This allows for precise control of adhesive pressure and position to prevent glass chipping and cracking, and precise control of the sticker's application position to avoid misalignment. This automated and precise application of the protective film sticker overcomes the shortcomings of existing manual application methods, effectively improving the product yield of the applied protective film sticker.
[0128] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention for those skilled in the art.
