Description

Technical Field

[0001] The present invention relates to the field of electronic paper module production and manufacturing, and in particular to a method and system for attaching an easily-tearable protective film. Background Art

[0002] Electronic paper modules are now widely used in supermarket price tags, e-books, mobile phones and other electronic devices. The use of easy-to-tear stickers is to facilitate the removal of protective films attached to LCD, LCM, TP and other liquid crystal panels, which is convenient, time-saving and leaves no traces. At present, the manual operation process of attaching PS protective film easy-to-tear stickers in the production of electronic paper modules is as follows: manually taking materials from the tray, scraping glue with aluminum strips, applying easy-to-tear stickers, pre-tearing the feet and putting the products back into the tray.

[0003] At present, the easy-to-tear sticker application of PS protective film in the production of electronic paper modules is all done manually, and a certain number of personnel are required to perform the operation on each line and each shift. With the increase in market demand, the current manual operation process of easy-to-tear sticker application of PS protective film in the production of electronic paper modules has gradually revealed its shortcomings: the aluminum strip scraping process requires high requirements for strength and position control, excessive force during manual operation will cause glass edge cracking, position deviation will easily scrape off the IC protective silicone, and manual easy-to-tear sticker application is prone to deviation, which greatly affects the product yield and causes the failure of automatic equipment to tear the film during customer module assembly. In addition, the operation process of easy-to-tear sticker application of PS protective film has high requirements for personnel, long training time, and frequent personnel changes also have a great impact on product yield and easy-to-tear sticker application consistency. Summary of the invention

[0004] The present invention provides a method and system for attaching a protective film easy-to-tear sticker to solve the above technical problems, overcome the shortcomings and deficiencies of the existing manual attachment of the protective film easy-to-tear sticker, and effectively improve the product yield of the protective film easy-to-tear sticker.

[0005] In order to solve the above technical problems, the present invention provides a method for attaching a protective film that is easy to tear off, which is applied to a display screen module. A protective film is attached to the upper surface of the display screen module. The attachment method comprises:

[0006] The current display screen module is moved to a preset scraping position, and residual glue of the current display screen module is scraped off at the preset position based on a preset scraping pressure to obtain a scraped display screen module;

[0007] Move the scraped display screen module to the preset labeling position, and attach the protective film easy-to-tear sticker to the preset area of ​​the protective film to complete the attachment of the protective film easy-to-tear sticker.

[0008] The beneficial effects of the present invention are:

[0009] Compared with the existing manual attachment of protective film easy-tear stickers, it is difficult to control the scraping force and position, and the manual attachment of protective film easy-tear stickers is prone to deviation, affecting the product yield and causing the failure of automated equipment to tear the film when assembling customer modules. The present invention transports the current display screen module to a preset scraping position, and scrapes off the residual glue of the current display screen module at a preset position based on a preset scraping pressure to obtain a glue-scraped display screen module, transports the glue-scraped display screen module to a preset labeling position, and attaches the protective film easy-tear sticker to the preset area of ​​the protective film, can accurately control the scraping pressure and the scraping position to avoid glass chipping and cracking, and accurately control the attachment position of the protective film easy-tear sticker to avoid deviation, thereby achieving automated and accurate attachment of the protective film easy-tear sticker, overcoming the shortcomings and deficiencies of the existing manual attachment of the protective film easy-tear sticker, and effectively improving the product yield of the protective film easy-tear sticker attachment.

[0010] As a preferred solution, after the current display screen module is moved to a preset scraping position and residual glue of the current display screen module is scraped off at a preset position based on a preset scraping pressure to obtain a scraped display screen module, the method further includes:

[0011] The glue-scraped display screen module is placed at a preset starting position, and the glue-scraped display screen module is horizontally rotated at a preset angle, and the protective film is pre-torn from the upper surface of the glue-scraped display screen module at a preset angle to obtain a starting display screen module;

[0012] Move the raised display screen module to the preset labeling position, and attach the easy-tear sticker of the protective film to the preset area of ​​the protective film to complete the easy-tear sticker of the protective film.

[0013] The upper surface of the display screen module is tightly attached to the protective film. This preferred solution pre-teares the protective film from the upper surface of the display screen module with glue scraped off at a preset angle to achieve pre-lifting and pre-tearing operations of the protective film, ensuring that the user can smoothly tear off the protective film through the easy-to-tear sticker of the protective film, making it more convenient to tear off the protective film on the upper surface of the display screen module, thereby improving the user experience.

[0014] This preferred solution also rotates the scraped display screen module horizontally by a preset angle before pre-tearing the protective film from the upper surface of the scraped display screen module at a preset angle. By setting the preset angle, the pre-tearing and pre-tearing operations of the protective film in different directions can be satisfied.

[0015] As a preferred embodiment, the method for attaching a protective film that is easy to tear off also includes:

[0016] When the protective film is not successfully torn off from the upper surface of the display screen module with the glue scraped off to a preset angle, a kick-off failure signal is generated;

[0017] In response to the kick-off failure signal, the scraped display screen module is regarded as a defective product and discarded.

[0018] If the protective film is not successfully torn off from the upper surface of the glue-scraped display screen module at a preset angle, the glue-scraped display screen module fails to lift off, indicating that the protective film is too tightly attached to the upper surface of the glue-scraped display screen module, making it difficult for the user to subsequently tear off the protective film from the upper surface of the display screen module through the easy-to-tear protective film sticker, resulting in a poor user experience. The preferred solution treats the glue-scraped display screen module that fails to lift off as an unqualified product and discards it, which can ensure that the display screen modules that the user receives are products with easy-to-tear protective films, allowing the user to simply and conveniently tear off the protective film from the upper surface of the display screen module through the easy-to-tear protective film sticker, thereby improving the user experience.

[0019] As a preferred solution, the method of moving the current display screen module to the preset scraping position includes: moving the current display screen module to the preset scraping position, and performing position correction on the current display screen module;

[0020] The step of moving the glue-scraped display screen module to the preset labeling position includes: moving the glue-scraped display screen module to the preset labeling position, and performing position correction on the glue-scraped display screen module;

[0021] Placing the glue-scraped display screen module to the preset starting position includes: placing the glue-scraped display screen module to the preset starting position, and performing position correction on the glue-scraped display screen module;

[0022] The method of moving the raised display screen module to a preset labeling position includes: moving the raised display screen module to the preset labeling position, and performing position correction on the raised display screen module.

[0023] This preferred solution also performs position correction on the display screen module after the display screen module is moved to the corresponding processing position, which helps to reduce the position deviation caused by moving the display screen module to the corresponding processing position and ensure the consistency of the product during subsequent processing. When the product is placed in the correct position, subsequent processing steps are easier to carry out, avoiding operational problems caused by position deviation and ensuring product quality. Position correction can avoid duplication of work and errors caused by improper positioning, reduce the time for rework and correction, and thus improve overall work efficiency.

[0024] As a preferred solution, before the current display screen module is moved to the preset scraping position, the method further includes: cleaning the surface of the initial display screen module to obtain the current display screen module.

[0025] Before the display screen module is moved to the preset scraping position, the preferred solution also cleans the surface of the display screen module to remove impurities such as dust, grease, and stains. After cleaning, the surface of the display screen module is smoother and cleaner, which is conducive to the adhesive on the protective film easy-to-tear sticker to better contact with the surface of the display screen module, enhance the adhesion, and make the protective film easy-to-tear sticker more firmly adhered to the module, ensuring that the subsequently attached protective film easy-to-tear sticker can fit tightly on the surface of the display screen module, avoiding problems such as bubbles and warping, thereby improving the pasting effect and aesthetics, and extending the service life of the protective film easy-to-tear sticker.

[0026] Accordingly, in order to solve the above technical problems, the present invention also provides a protective film easy-to-tear attachment system, which is applied to a display screen module, and a protective film is attached to the upper surface of the display screen module. The attachment system includes: a control device, a scraping mechanism, an attachment mechanism and a conveying mechanism;

[0027] Wherein, the scraping mechanism is used to scrape off the residual glue of the current display screen module;

[0028] The attaching mechanism is used to attach the protective film easy-tear sticker to a preset area of ​​the protective film;

[0029] The transport mechanism is used to transport the display screen module to a preset processing position;

[0030] The control device is used to control the conveying mechanism to convey the current display screen module to a preset scraping position, and control the scraping mechanism to scrape off the residual glue of the current display screen module at a preset position based on a preset scraping pressure to obtain a scraped display screen module; control the conveying mechanism to convey the scraped display screen module to a preset labeling position, and control the attaching mechanism to attach the easy-tear sticker of the protective film to a preset area of ​​the protective film to complete the attachment of the easy-tear sticker of the protective film.

[0031] The present invention can realize the automatic and precise attachment of the protective film, and overcome the shortcomings and deficiencies of the existing manual attachment of the protective film, and effectively improve the product yield rate.

[0032] As a preferred embodiment, the protective film easy-to-tear attachment system further includes a kicking mechanism; the kicking mechanism is used to horizontally rotate the glue-scraped display screen module by a preset angle, thereby pre-tearing the protective film from the upper surface of the glue-scraped display screen module by a preset angle;

[0033] The control device is also used to control the conveying mechanism to place the glue-scraped display screen module to a preset starting position, and control the starting mechanism to horizontally rotate the glue-scraped display screen module by a preset angle, and then control the starting mechanism to pre-tear the protective film from the upper surface of the glue-scraped display screen module at a preset angle to obtain the starting display screen module; control the conveying mechanism to convey the starting display screen module to a preset labeling position, and control the attaching mechanism to attach the easy-tear sticker of the protective film to the preset area of ​​the protective film to complete the attachment of the easy-tear sticker of the protective film.

[0034] The upper surface of the display screen module is tightly attached to the protective film. This preferred solution controls the kicking mechanism to pre-tear the protective film from the upper surface of the display screen module with glue scraped at a preset angle, thereby realizing the pre-lifting and pre-tearing operations of the protective film, ensuring that the user can smoothly tear off the protective film through the easy-to-tear protective film sticker, making it more convenient to tear off the protective film on the upper surface of the display screen module, thereby improving the user experience.

[0035] This preferred solution also controls the lifting mechanism to horizontally rotate the glue-scraped display screen module to a preset angle before pre-tearing the protective film from the upper surface of the glue-scraped display screen module to a preset angle. By setting the preset angle, the pre-lifting and pre-tearing operations of the protective film in different directions can be satisfied.

[0036] As a preferred embodiment, the protective film easy-to-tear attachment system further includes an angle detection mechanism; the angle detection mechanism is used to generate a kick failure signal when the kick mechanism fails to successfully tear the protective film from the upper surface of the glue-scraped display screen module at a preset angle;

[0037] The control device is also used for responding to the kick-off failure signal, treating the glue-scraped display screen module as a defective product and controlling the conveying mechanism to convey the glue-scraped display screen module to a conveyor belt for unloading defective products.

[0038] If the protective film is not successfully torn off from the upper surface of the glue-scraped display screen module at a preset angle, the glue-scraped display screen module fails to lift off, indicating that the protective film is too tightly attached to the upper surface of the glue-scraped display screen module, resulting in difficulty for users to subsequently tear off the protective film from the upper surface of the display screen module through the easy-to-tear protective film sticker, resulting in a poor user experience. This preferred solution treats the glue-scraped display screen module that fails to lift off as an unqualified product and transports it to an unqualified product unloading belt, which can ensure that the display screen modules received by users are products with easy-to-tear protective films, allowing users to simply and conveniently tear off the protective film from the upper surface of the display screen module through the easy-to-tear protective film sticker, thereby improving user experience.

[0039] As a preferred solution, the protective film easy-to-tear attachment system further includes a position correction mechanism; the position correction mechanism is used to correct the position of the display screen module after the conveying mechanism places the display screen module at the preset processing position;

[0041] This preferred solution also performs position correction on the display screen module controlled by the position correction mechanism after the control conveying mechanism conveys the display screen module to the corresponding processing position, which helps to reduce the position deviation caused by conveying the display screen module to the corresponding processing position and ensure the consistency of the product during subsequent processing.

Position correction can avoid duplication of work and errors caused by improper positioning, reduce the time for rework and correction, and thus improve overall work efficiency.

[0042] As a preferred embodiment, the protective film easy-to-tear attachment system further includes a cleaning mechanism; the cleaning mechanism is used to clean the surface of the initial display screen module;

[0043] The control device is also used to control the cleaning mechanism to clean the surface of the initial display screen module before controlling the transport mechanism to transport the current display screen module to the preset scraping position to obtain the current display screen module.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] At present, the easy-to-tear sticker application of PS protective film in the production of electronic paper modules is all done manually, and a certain number of personnel are required to perform the operation on each line and each shift. With the increase in market demand, the current manual operation process of easy-to-tear sticker application of PS protective film in the production of electronic paper modules has gradually revealed its shortcomings: the aluminum strip scraping process requires high requirements for strength and position control, excessive force during manual operation will cause glass edge cracking, position deviation will easily scrape off the IC protective silicone, and manual easy-to-tear sticker application is prone to deviation, which greatly affects the product yield and causes the failure of automatic equipment to tear the film during customer module assembly. In addition, the operation process of easy-to-tear sticker application of PS protective film has high requirements for personnel, long training time, and frequent personnel changes also have a great impact on product yield and easy-to-tear sticker application consistency.

[0050] Embodiment 1

[0051] In order to solve the above technical problems, the present invention provides a method and system for attaching a protective film easy-to-tear sticker, which can overcome the shortcomings and deficiencies of the existing manual attachment of protective film easy-to-tear stickers and effectively improve the product yield of the protective film easy-to-tear sticker attachment.

[0052] Please refer to Figure 1 , which is a flow chart of an embodiment of a method for attaching a protective film that is easy to tear off provided by an embodiment of the present invention.

[0053] The method for attaching a protective film that is easy to tear is applied to a display screen module, and a protective film is attached to the upper surface of the display screen module. Figure 1 As shown, the method for attaching the protective film easy-to-tear sticker includes steps 101 to 102, specifically:

[0054] Step 101: moving the current display screen module to a preset scraping position, and scraping off the residual glue of the current display screen module at a preset position based on a preset scraping pressure to obtain a scraped display screen module;

[0055] Step 102: Move the scraped display screen module to a preset labeling position, and attach 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.

[0056] Furthermore, after the current display screen module is transported to a preset scraping position and residual glue of the current display screen module is scraped off at a preset position based on a preset scraping pressure to obtain a scraped display screen module, the method further includes:

[0057] The glue-scraped display screen module is placed at a preset starting position, and the glue-scraped display screen module is horizontally rotated at a preset angle, and the protective film is pre-torn from the upper surface of the glue-scraped display screen module at a preset angle to obtain a starting display screen module;

[0058] Move the raised display screen module to the preset labeling position, and attach the easy-tear sticker of the protective film to the preset area of ​​the protective film to complete the easy-tear sticker of the protective film.

[0059] The upper surface of the display screen module is tightly attached to the protective film. The present invention realizes the pre-lifting and pre-tearing operations of the protective film by pre-tearing the protective film from the upper surface of the display screen module where glue has been scraped at a preset angle, thereby ensuring that the user can smoothly tear off the protective film through the easy-to-tear protective film sticker, making it more convenient to tear off the protective film on the upper surface of the display screen module, thereby improving the user experience.

[0060] Before pre-tearing the protective film from the upper surface of the glue-scraped display screen module at a preset angle, the present invention also rotates the glue-scraped display screen module horizontally clockwise or counterclockwise at a preset angle. By setting the preset angle, the pre-tearing 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 attaching a protective film that is easy to tear off also includes:

[0063] When the protective film is not successfully torn off from the upper surface of the display screen module with the glue scraped off to a preset angle, a kick-off failure signal is generated;

[0064] In response to the kick-off failure signal, the scraped display screen module is regarded as a defective product and discarded.

[0065] In this embodiment, the optical fiber can detect the angle between the protective film and the upper surface of the display screen module where the glue has been scraped to determine whether the protective film has been successfully torn off from the upper surface of the display screen module at a preset angle. When the optical fiber senses that the angle between the protective film and the upper surface of the display screen module where the glue has been scraped reaches or exceeds a certain threshold, a corresponding signal will be output. At this time, it is determined that the protective film and the upper surface of the display screen module where the glue has been scraped form a certain angle, that is, the protective film has been successfully torn off from the upper surface of the display screen module at a preset angle, and the kicking is successful. When the optical fiber does not detect that the protective film and the upper surface of the display screen module where the glue has been scraped form a certain angle, a kicking failure signal is generated.

[0066] If the protective film is not successfully torn off from the upper surface of the glue-scraped display screen module at a preset angle, the glue-scraped display screen module fails to lift off, indicating that the protective film is too tightly attached to the upper surface of the glue-scraped display screen module, resulting in difficulty for the user to subsequently tear off the protective film from the upper surface of the display screen module through the protective film easy-tear sticker, resulting in a poor user experience. The present invention treats the glue-scraped display screen module that fails to lift off as an unqualified product and discards it, which can ensure that the display screen modules obtained by the user are products with easy to tear off the protective film, allowing the user to simply and conveniently tear off the protective film from the upper surface of the display screen module through the protective film easy-tear sticker, thereby improving the user experience.

[0067] Further, the said moving the current display screen module to the preset scraping position includes: moving the current display screen module to the preset scraping position, and performing position correction on the current display screen module;

[0068] The step of moving the glue-scraped display screen module to the preset labeling position includes: moving the glue-scraped display screen module to the preset labeling position, and performing position correction on the glue-scraped display screen module;

[0069] Placing the glue-scraped display screen module to the preset starting position includes: placing the glue-scraped display screen module to the preset starting position, and performing position correction on the glue-scraped display screen module;

[0070] The method of moving the raised display screen module to a preset labeling position includes: moving the raised display screen module to the preset labeling position, and performing position correction on the raised display screen module.

[0071] In this embodiment, the process of position correction is: obtaining the overlapping area between the current position of the display screen module and the preset correction position, obtaining movement data or movement path based on the overlapping area, the movement data including the rotation angle, movement direction and movement distance, moving the display screen module according to the movement data or movement path and updating the current position of the display screen module until the current position of the display screen module completely overlaps with the preset correction position, and the position correction is completed.

[0072] After the display screen module is transported to the corresponding processing position, the present invention also performs position correction on the display screen module, which helps to reduce the position deviation caused by transporting the display screen module to the corresponding processing position and ensure the consistency of the product during subsequent processing. When the product is placed in the correct position, the subsequent processing steps are easier to carry out, avoiding operational problems caused by position deviation and ensuring product quality. In addition, position correction can avoid duplication of work and errors caused by improper positioning, reduce the time for rework and correction, and thus improve overall work efficiency.

[0073] Furthermore, the said moving the current display screen module to the preset scraping position includes: moving the scraped display screen module to the preset labeling position, performing position correction on the scraped display screen module, and vacuum adsorbing the scraped display screen module after correction. In this embodiment, after the display screen module is moved to the corresponding processing position, the display screen module is position corrected, and after the position correction, the display screen module is vacuum adsorbed. The vacuum adsorption method ensures that the display screen module will not move or vibrate during the processing, reduces the processing error caused by movement or vibration, and improves the accuracy and stability of the processing. In addition, for some fragile or surface-sensitive products, such as electronic paper modules made of glass materials, traditional clamping methods may cause damage to them. Vacuum adsorption is a contactless fixing method. In this embodiment, the display screen module is tightly adsorbed to the preset processing position through vacuum adsorption to avoid mechanical damage or contamination to the product surface.

[0074] Furthermore, before the current display screen module is carried to the preset scraping position, the method further includes: cleaning the surface of the initial display screen module to obtain the current display screen module.

[0075] Before the display screen module is moved to the preset scraping position, the present invention also cleans the surface of the display screen module to remove impurities such as dust, grease, stains, etc. After cleaning, the surface of the display screen module is smoother and cleaner, which is conducive to the adhesive on the protective film easy-to-tear sticker to better contact with the surface of the display screen module, enhance the adhesion, and make the protective film easy-to-tear sticker more firmly adhered to the module, ensuring that the subsequently attached protective film easy-to-tear sticker can be closely attached to the surface of the display screen module, avoiding problems such as bubbles and warping, thereby improving the pasting effect and aesthetics, and extending the service life of the protective film easy-to-tear sticker.

[0076] Accordingly, in order to solve the above technical problems, the present invention also provides a protective film easy-to-tear attachment system, which is applied to a display screen module, and a protective film is attached to the upper surface of the display screen module. The attachment system includes: a control device, a scraping mechanism, an attachment mechanism and a conveying mechanism;

[0077] Wherein, the scraping mechanism is used to scrape off the residual glue of the current display screen module;

[0078] The attaching mechanism is used to attach the protective film easy-tear sticker to a preset area of ​​the protective film;

[0079] The transport mechanism is used to transport the display screen module to a preset processing position;

[0080] The control device is used to control the conveying mechanism to convey the current display screen module to a preset scraping position, and control the scraping mechanism to scrape off the residual glue of the current display screen module at a preset position based on a preset scraping pressure to obtain a scraped display screen module; control the conveying mechanism to convey the scraped display screen module to a preset labeling position, and control the attaching mechanism to attach the easy-tear sticker of the protective film to a preset area of ​​the protective film to complete the attachment of the easy-tear sticker of the protective film.

[0081] In this embodiment, the transport mechanism includes a plurality of transport arms.

[0082] Furthermore, the protective film easy-to-tear attachment system further includes a kicking mechanism; the kicking mechanism is used to horizontally rotate the glue-scraped display screen module by a preset angle, thereby pre-tearing the protective film from the upper surface of the glue-scraped display screen module by a preset angle;

[0083] The control device is also used to control the conveying mechanism to place the glue-scraped display screen module to a preset starting position, and control the starting mechanism to horizontally rotate the glue-scraped display screen module by a preset angle, and then control the starting mechanism to pre-tear the protective film from the upper surface of the glue-scraped display screen module at a preset angle to obtain the starting display screen module; control the conveying mechanism to convey the starting display screen module to a preset labeling position, and control the attaching mechanism to attach the easy-tear sticker of the protective film to the preset area of ​​the protective film to complete the attachment of the easy-tear sticker of the protective film.

[0084] In this embodiment, the preset processing positions include a preset glue scraping position, a preset labeling position and a preset kicking position.

[0085] The upper surface of the display screen module is tightly attached to the protective film. The present invention controls the kicking mechanism to pre-tear the protective film from the upper surface of the display screen module with glue scraped at a preset angle, thereby realizing the pre-lifting and pre-tearing operations of the protective film, ensuring that the user can smoothly tear off the protective film through the easy-to-tear protective film sticker, making it more convenient to tear off the protective film on the upper surface of the display screen module, thereby improving the user experience.

[0086] Before the protective film is pre-torn from the upper surface of the display screen module on which the glue has been scraped at a preset angle, the present invention also controls the kicking mechanism to horizontally rotate the display screen module on which the glue has been scraped clockwise or counterclockwise at a preset angle. By setting the preset angle, the pre-lifting and pre-tearing operations of the protective film in different directions can be satisfied.

[0087] In this embodiment, the kicking mechanism includes a kicking robot and an angle wheel; under the control of the control device, the kicking robot aligns the angle wheel with a corner of the protective film to ensure that the edge of the angle wheel is tightly fitted with the protective film, and the kicking robot applies a preset force to the angle wheel to make the angle wheel gradually cut into the gap between the protective film and the display screen module. After the angle wheel successfully cuts into the gap, the angle wheel is slowly pulled upward or to one side based on a preset speed to tear the protective film from the display screen module at a certain angle.

[0088] In this embodiment, further, the scraper mechanism includes: a scraper head control component and a scraper head; the scraper head control component controls the movement of the scraper head under the control of the control device, so that the scraper head scrapes off the residual glue of the current display screen module at a preset position based on a preset scraper pressure.

[0089] In this embodiment, the scraper head control component includes an X-direction moving module, a Y-direction moving module and a Z-direction moving module; the scraper head is moved in the X direction by the X-direction moving module, the scraper head is moved in the Y direction by the Y-direction moving module, and the scraper head is moved in the Z direction by the Z-direction moving module.

[0090] In this embodiment, the scraping pressure 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 adjusts the scraping pressure according to the data collected by the pressure sensor.

[0091] In this embodiment, the control device locates the residual glue area on the display screen module through machine vision algorithm or sensor technology, controls the X-axis moving module, the Y-axis moving module and the Z-axis moving module based on the residual glue area, and then controls the scraper head to contact the residual glue area and move on the residual glue, thereby scraping the residual glue from the surface of the display screen module. After scraping, the cleaning mechanism is controlled to use a cleaning tool and a cleaning agent to clean the surface of the display screen module to ensure that there is no residual glue and traces left by the scraper head.

[0093] The label delivery component is used to move the protective film easy-to-tear sticker to a preset label delivery position;

[0094] The driving motor controls the attachment robot to move under the control of the control device, so that the attachment robot obtains the easy-tear label of the protective film at the preset label delivery position, and attaches the easy-tear label to the preset area of ​​the protective film;

[0095] Specifically, the attachment robot includes an attachment robot arm and an end effector;

[0096] The attaching robot arm drives the end effector to move under the drive of the driving motor, so that when the end effector moves to the preset label delivery position, the easy-to-tear label of the protective film is obtained. Then, the attaching robot arm continues to drive the end effector to move above the preset area of ​​the protective film under the control of the driving motor, and then controls the end effector to attach the easy-to-tear label to the preset area of ​​the protective film, thereby completing the attachment of the easy-to-tear label of the protective film.

[0097] In this embodiment, the driving motor is used to drive the attaching robot to move on the X-axis, Y-axis and Z-axis and to drive the attaching robot to rotate on the rotating axis to meet the requirements of easy-tear attachment of the protective film in different directions of the display screen module.

[0098] In this embodiment, the end effector is a suction cup or a clamp.

[0099] In this embodiment, the label delivery component will peel off the protective film easy-to-tear label and deliver it to the preset label delivery position. The delivery position is consistent each time, ensuring the consistency of the protective film easy-to-tear label obtained by the attaching robot.

[0100] Furthermore, the said protective film easy-to-tear attachment system also includes a number of vacuum adsorption components, which are used to use negative pressure to tightly adsorb the display screen module on the preset processing position, to ensure that the display screen module will not move or vibrate during the processing, to reduce the processing error caused by movement or vibration, and to improve the accuracy and stability of the processing. In addition, for some fragile or surface-sensitive products, such as electronic paper modules made of glass materials, the traditional clamping method may cause damage to them. Vacuum adsorption is a non-contact fixing method. In this embodiment, the display screen module is tightly adsorbed on the preset processing position by the vacuum adsorption component to avoid mechanical damage or contamination to the product surface.

[0101] Furthermore, the attachment system for easy-tear protection film further comprises an angle detection mechanism; the angle detection mechanism is used to generate a kick failure signal when the kick mechanism fails to successfully tear the protection film from the upper surface of the display screen module where the glue has been scraped to a preset angle;

[0102] The control device is also used for responding to the kick-off failure signal, treating the glue-scraped display screen module as a defective product and controlling the conveying mechanism to convey the glue-scraped display screen module to a conveyor belt for unloading defective products.

[0103] If the protective film is not successfully torn off from the upper surface of the glue-scraped display screen module at a preset angle, the glue-scraped display screen module fails to lift off, indicating that the protective film is too tightly attached to the upper surface of the glue-scraped display screen module, resulting in difficulty for the user to subsequently tear off the protective film from the upper surface of the display screen module through the protective film easy-tear sticker, resulting in a poor user experience. The present invention treats the glue-scraped display screen module that fails to lift off as a defective product and transports it to a conveyor for unqualified products, thereby ensuring that the display screen modules obtained by the user are products from which the protective film is easy to tear off, allowing the user to simply and conveniently tear off the protective film from the upper surface of the display screen module through the protective film easy-tear sticker, thereby improving the user experience.

[0104] In this embodiment, the optical fiber can detect the angle between the protective film and the upper surface of the display screen module where the glue has been scraped to determine whether the protective film has been successfully torn off from the upper surface of the display screen module at a preset angle. When the optical fiber senses that the angle between the protective film and the upper surface of the display screen module where the glue has been scraped reaches or exceeds a certain threshold, a corresponding signal will be output. At this time, it is determined that the protective film and the upper surface of the display screen module where the glue has been scraped form a certain angle, that is, the protective film has been successfully torn off from the upper surface of the display screen module at a preset angle, and the kicking is successful. When the optical fiber does not detect that the protective film and the upper surface of the display screen module where the glue has been scraped form a certain angle, a kicking failure signal is generated.

[0105] Furthermore, the protective film easy-to-tear attachment system further includes a position correction mechanism; the position correction mechanism is used to correct the position of the display screen module after the conveying mechanism places the display screen module at a preset processing position;

[0106] The control device is also used to control the position correction mechanism to perform position correction on the display screen module after controlling the transport mechanism to place the display screen module at a preset processing position.

[0107] After the control transport mechanism transports the display screen module to the corresponding processing position, the present invention also performs position correction on the display screen module controlled by the position correction mechanism, which helps to reduce the position deviation caused by transporting the display screen module to the corresponding processing position and ensure the consistency of the product during subsequent processing. When the product is placed in the correct position, the subsequent processing steps are easier to carry out, avoiding operational problems caused by position deviation and ensuring product quality. In addition, position correction can avoid duplication of work and errors caused by improper positioning, reduce the time for rework and correction, and thus improve overall work efficiency.

[0108] In this embodiment, the position correction mechanism is a cylinder, and the position correction of the display screen module in the X and Y directions is realized by the cylinder; the process of position correction is: under the control of the control device, the cylinder is fitted with the side of the display screen module, and the overlapping area between the current position of the display screen module and the preset correction position is obtained, and the movement data or the movement path is obtained based on the overlapping area. The movement data includes the rotation angle, the movement direction and the movement distance, and the cylinder is controlled to move according to the movement data or the movement path, thereby driving the display screen module to move and update the current position of the display screen module, until the current position of the display screen module completely overlaps with the preset correction position, and the position correction is completed.

[0109] Furthermore, the protective film easy-to-tear attachment system further includes a cleaning mechanism; the cleaning mechanism is used to clean the surface of the initial display screen module;

[0110] The control device is also used to control the cleaning mechanism to clean the surface of the initial display screen module before controlling the transport mechanism to transport the current display screen module to the preset scraping position to obtain the current display screen module.

[0111] Furthermore, the cleaning mechanism includes a rotating mechanical arm and a cleaning mechanical arm. The rotating mechanical arm flips the initial display screen module so that the cleaning mechanical arm wipes the surface of the initial display screen module with a dust-free cloth and alcohol.

[0112] Before controlling the transport mechanism to transport the display screen module to the preset scraping position, the present invention also controls the cleaning mechanism to clean the surface of the display screen module, so as to remove impurities such as dust, grease, stains, etc. After cleaning, the surface of the display screen module is smoother and cleaner, which is conducive to the adhesive on the protective film easy-to-tear sticker to better contact with the surface of the display screen module, enhance the adhesion, and make the protective film easy-to-tear sticker more firmly adhered to the module, ensuring that the subsequently attached protective film easy-to-tear sticker can be closely attached to the surface of the display screen module, avoiding problems such as bubbles and warping, thereby improving the pasting effect and aesthetics, and extending the service life of the protective film easy-to-tear sticker.

[0113] Please refer to the following Figure 2 ,for Figure 2 A schematic structural diagram of an embodiment of an easy-to-tear protective film attachment system provided by the present invention.

[0114] like Figure 2 As shown, the protective film easy-to-tear attachment system comprises: a control device, a glue scraping mechanism 1, a kicking mechanism 2, an attachment mechanism 3 and a conveying mechanism 4;

[0115] The scraping mechanism 1 is used to scrape off the residual glue of the current display screen module;

[0116] The kick mechanism 2 is used to horizontally rotate the glue-scraped display screen module by a preset angle, and then pre-tear the protective film from the upper surface of the glue-scraped display screen module by a preset angle;

[0117] The attaching mechanism 3 is used to attach the protective film easy-tear sticker to the preset area of ​​the protective film;

[0118] The transport mechanism 4 is used to transport the display screen module to a preset processing position;

[0119] The control device is used to control the scraping mechanism 1, the kicking mechanism 2, the attaching mechanism 3 and the conveying mechanism 4 to perform corresponding processing operations.

[0120] In this embodiment, the transport mechanism 4 includes a plurality of transport arms 41 .

[0121] In this embodiment, the attaching system of the protective film easy-tear sticker further includes a cleaning mechanism; the cleaning mechanism is used to clean the surface of the initial display screen module.

[0122] like Figure 2 As shown, the protective film easy-to-tear attachment system also includes: a loading platform 5 and a unloading platform 6; the loading platform 5 is used to transport and place a number of current display screen modules, so that the conveying mechanism 4 transports the current display screen modules to the preset scraping position 11; the unloading platform 6 is used to place and transport a number of attached display screen modules.

[0123] Figure 2The working process of the protective film easy-to-tear attachment system shown is as follows: each current display screen module cleaned by the cleaning mechanism will be placed on the loading platform 5, and under the control of the control device, the transport arm 41 will transport the current display screen module on the loading platform 5 to the preset scraping position 11, and the position correction mechanism will perform position correction on the current display screen module. After correction, the vacuum adsorption component will adsorb and fix the current display screen module, and the scraping mechanism 1 will scrape off the residual glue of the current display screen module at the preset position based on the preset scraping pressure to obtain a scraped display screen module; after the scraping is completed, the transport arm 41 will place the scraped display screen module to the preset starting position 21, and the position correction mechanism will perform position correction on the scraped display screen module. After correction, the vacuum adsorption component will adsorb and fix the current display screen module. The lifting mechanism 2 adsorbs and fixes the glue-scraped display screen module, and the lifting mechanism 2 horizontally rotates the glue-scraped display screen module by a preset angle. Then the lifting mechanism 2 pre-teares the protective film from the upper surface of the glue-scraped display screen module at a preset angle to obtain a lifted display screen module. The glue-scraped display screen module that fails to lift the glue will be transported by the transport arm 41 to the unqualified product unloading belt; after the lifting is completed, the transport arm 41 transports the lifted display screen module to the preset labeling position 31, and the position correction mechanism performs position correction on the lifted display screen module. After the correction, the vacuum adsorption component adsorbs and fixes the lifted display screen module, and then the attaching mechanism 3 attaches the easy-tear sticker of the protective film to the preset area of ​​the protective film, completing the attachment of the easy-tear sticker of the protective film to obtain an attached display screen module.

[0124]

[0125] In the process of attaching the existing manual easy-to-tear protective film stickers, the protective film cannot be attached properly and cannot be torn off, resulting in the failure of the automatic equipment to tear the film during the display module assembly process. In addition, when manually attaching the easy-to-tear protective film stickers, the attachment accuracy is poor and the position is not uniform. As shown in the above table, compared with the existing manual labeling production method, after applying the attachment method and system of the easy-to-tear protective film stickers proposed in the present invention, the product yield, attachment efficiency and product production capacity of the easy-to-tear protective film stickers are greatly improved, and the labor cost is also reduced.

[0126] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0127] Compared with the existing manual attachment of protective film easy-tear stickers, it is difficult to control the scraping force and position, and the manual attachment of protective film easy-tear stickers is prone to deviation, affecting the product yield and causing the failure of automated equipment to tear the film when assembling customer modules. The present invention transports the current display screen module to a preset scraping position, and scrapes off the residual glue of the current display screen module at a preset position based on a preset scraping pressure to obtain a glue-scraped display screen module, transports the glue-scraped display screen module to a preset labeling position, and attaches the protective film easy-tear sticker to the preset area of ​​the protective film, can accurately control the scraping pressure and the scraping position to avoid glass chipping and cracking, and accurately control the attachment position of the protective film easy-tear sticker to avoid deviation, thereby achieving automated and accurate attachment of the protective film easy-tear sticker, overcoming the shortcomings and deficiencies of the existing manual attachment of the protective film easy-tear sticker, and effectively improving the product yield of the protective film easy-tear sticker attachment.
