[0032] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0034] The applicant discovered that in the prior art, the film-peeling roller is easily affected by the incoming material condition of the display module. When the surface of the display module is covered with impurities such as electrostatic liquid and micro-dust particles, the impurities are easily transferred to the film-peeling roller, which reduces the stickiness of the film-peeling roller or even causes it to fail, resulting in film peeling and affecting the life of the film-peeling roller, thereby affecting the yield rate and production efficiency of the display module.

[0035] In view of the above problems, the applicant proposes a film peeling device for peeling off a film. The film peeling device includes a flexible belt and a driving mechanism. The flexible belt extends along a preset path and includes a cleaning section and an adhesive section arranged along the preset path. The cleaning section is used to wipe the film, and the adhesive section is used to stick the film. The driving mechanism is connected to the flexible belt and is used to drive the flexible belt to move along the preset path.

[0036] The film-peeling device provided in this application includes a flexible belt and a driving mechanism. The flexible belt extends along a preset path and includes a cleaning section and an adhesive section arranged along the preset path. The driving mechanism is connected to the flexible belt and is used to drive the flexible belt to move along the preset path. During the movement of the flexible belt, the cleaning section in the flexible belt wipes the surface of the film to remove dirt from the film surface. Then, the driving mechanism continues to drive the flexible belt to move, so that the adhesive section adheres to the film and peels off the film. By cleaning the film surface with the cleaning section before adhering the film, the effect of the adhesive section adhering to the film is improved, the probability of film peeling off is reduced, thereby improving the film-peeling efficiency and the yield of the display module.

[0037] The display module provided in the embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that the x-direction in the drawings is a first direction, and the y-direction is a second direction. In the drawings, for ease of drawing, the dimensions are not necessarily proportional to the actual dimensions.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 This is one of the main view structural schematic diagrams of the film-tearing device according to some embodiments of this application; Figure 2 An example is shown. Figure 1 A schematic diagram of the flexible strip after it has been unfolded, viewed from below.

[0039] like Figure 1 and Figure 2 As shown, this application provides a film peeling device for peeling off a film, including a flexible belt 10 and a driving mechanism 20. The flexible belt 10 extends and is formed along a preset path. The flexible belt 10 includes a cleaning section 11 and an adhesive section 12 arranged along the preset path. The cleaning section 11 is used to wipe the film, and the adhesive section 12 is used to stick the film. The driving mechanism 20 is connected to the flexible belt 10 and is used to drive the flexible belt 10 to move along the preset path.

[0040] Optionally, the display module includes a screen 100 and a thin film 101 attached to one side of the screen 100, with a flexible strip 10 located on the side of the thin film 101 facing away from the screen 100. The screen 100 and the thin film 101 extend along a first direction (x direction in the figure), which can be defined as the length direction of the screen 100 and the thin film 101. The preset path of the flexible strip 10 is consistent with the length direction of the flexible strip 10, that is, the flexible strip 10 extends along the length direction. The width of the flexible strip 10 is not less than the width of the thin film 101. The driving mechanism 20 drives the flexible strip 10 to move on the side of the thin film 101 facing away from the screen 100 and to contact the thin film 101, so that the cleaning section 11 and the adhesive section 12 alternately contact the thin film 101.

[0041] The film-removing device provided in this embodiment includes a flexible belt 10 and a driving mechanism 20. The flexible belt 10 extends along a preset path and includes a cleaning section 11 and an adhesive section 12 arranged along the preset path. The driving mechanism 20 is connected to the flexible belt 10 and is used to drive the flexible belt 10 to move along the preset path. During the movement of the flexible belt 10, the cleaning section 11 in the flexible belt 10 wipes the surface of the film 101 to remove dirt from the surface of the film 101. Then, the driving mechanism 20 continues to drive the flexible belt 10 to move, so that the adhesive section 12 adheres to the film 101 and peels the film 101 off the screen 100. By cleaning the surface of the film 101 with the cleaning section 11 before adhesion, the adhesion effect of the adhesive section 12 on the film 101 is improved, the probability of film peeling off is reduced, and thus the film-removing efficiency and the yield rate of the display module are improved.

[0042] In some alternative embodiments, multiple cleaning segments 11 and adhesive segments 12 are arranged alternately along a preset path of the flexible strip 10.

[0043] Optionally, the cleaning section 11 includes at least one of a lint-free cloth, a flexible sponge, and a flexible brush.

[0044] The film-tearing device provided in this embodiment, through multiple cleaning sections 11 and pasting sections 12 arranged alternately along a preset path of the flexible belt 10, enables continuous feeding of the display module in the production process of the display module, reduces the replacement frequency of the flexible belt 10, and thus improves the film-tearing efficiency and the production efficiency of the display module.

[0045] Please refer to Figure 3 , Figure 3 The second schematic diagram of the main structure of another example of a film-tearing device is shown.

[0046] In some alternative embodiments, the drive mechanism 20 includes a release roller 21 and a winding roller 22. The release roller 21 is connected to one end of the flexible belt 10 on a preset path, and the winding roller 22 is connected to the end of the flexible belt 10 away from the release roller 21, so that when the release roller 21 and the winding roller 22 rotate, the flexible belt 10 can be released from the release roller 21 and wound onto the winding roller 22.

[0047] Optionally, both the release roller 21 and the winding roller 22 are located on the side of the film 101 facing away from the screen body 100. When the release roller 21 and the winding roller 22 rotate, the flexible strip 10 located between the release roller 21 and the winding roller 22 contacts the film 101. The release roller 21 is used to release the unused cleaning section 11 and the adhesive section 12, and the winding roller 22 is used to wind the adhesive section 12 with the film 101 attached to it together with the film 101 and collect it onto the winding roller 22.

[0048] The film-peeling device provided in this embodiment, by releasing the rotation of the roller 21 and the winding roller 22, causes the flexible belt 10 to move unidirectionally along a preset trajectory, ensuring that each cleaning section 11 and the pasting section 12 contacts only one display module, thereby improving the effect of the film 101 pasted by the pasting section 12 and reducing the probability of film falling off. The rotating winding roller 22 collects the pasting section 12 and the film 101 on the pasting section 12, combining the film 101 corner raising and film peeling processes, further improving the film peeling efficiency and the production efficiency of the display modules.

[0049] Please refer to Figures 2 to 4 , Figure 4 The third schematic diagram of the main structure of another example of a film-tearing device is shown.

[0050] like Figures 2 to 4 As shown, in some alternative embodiments, the flexible strip 10 has a first surface 13 and a second surface 14 disposed opposite to each other, with the adhesive section 12 and the cleaning section 11 disposed on the first surface 13.

[0051] Optionally, the second surface 14 is wound around the release roller 21 and the winding roller 22, and the release roller 21 and the winding roller 22 rotate in the same direction, such as... Figure 3 As shown.

[0052] Optionally, the second surface 14 is wound around the release roller 21, and the first surface 13 is wound around the winding roller 22. The release roller 21 and the winding roller 22 rotate in opposite directions. Figure 4 As shown.

[0053] The film-tearing device provided in this embodiment can select different matching schemes between the flexible belt 10 and the drive mechanism 20 according to the actual production situation, thereby improving the applicability of the film-tearing device.

[0054] Please refer to Figure 5 , Figure 5 The fourth schematic diagram of the main structure of another example of a film-tearing device is shown.

[0055] like Figure 5 As shown, in some alternative embodiments, the film-tearing device may further include a drive roller 30 located on the side of the flexible strip 10 away from the film 101, and the drive roller 30 is configured to move in a direction away from or close to the flexible strip 10.

[0056] Optionally, the film-tearing device may also include a connecting arm 31 and a driving member (not shown), with the release roller 21 and the winding roller 22 located on both sides of the driving roller 30 along the preset path. The connecting arm 31 connects the driving roller 30 and the driving member, and the driving member is used to drive the connecting arm 31 to move the driving roller 30 in a direction away from or towards the flexible belt 10.

[0057] Optionally, the direction in which the drive roller 30 moves away from or towards the flexible belt 10 is defined as the second direction (the y-direction in the figure). The drive component can be a motor, cylinder, or hydraulic cylinder, etc. When the drive connecting arm 31 drives the drive roller 30 to approach the flexible belt 10 along the second direction y, the drive roller 30 abuts against the flexible belt 10 and drives the flexible belt 10 to approach the display module along the second direction y, causing the flexible belt 10 between the release roller 21 and the winding roller 22 to lengthen until the flexible belt 10 contacts the film 101. When the drive connecting arm 31 drives the drive roller 30 away from the flexible belt 10 along the second direction y, the flexible belt 10 between the release roller 21 and the winding roller 22 shortens until the flexible belt 10 moves away from the film 101.

[0058] Optionally, the flexible belt 10 has the characteristic of elastic deformation. When the drive roller 30 moves in a direction close to the flexible belt 10, the flexible belt 10 is stretched under the drive of the drive roller 30, thereby lengthening the flexible belt 10 between the release roller 21 and the winding roller 22. When the drive roller 30 moves in a direction away from the flexible belt 10, the flexible belt 10 retracts under the action of its own elastic potential energy, thereby shortening the flexible belt 10 between the release roller 21 and the winding roller 22.

[0059] Optionally, the film-tearing device may also include a control element (not shown), which is connected to the release roller 21 and / or the winding roller 22. The control element may be a microprocessor or similar component, and it controls the rotational speed of the release roller 21 and / or the winding roller 22. When the drive roller 30 moves in a direction close to the flexible belt 10, the control element controls the rotational speed of the release roller 21 to increase and / or controls the rotational speed of the winding roller 22 to decrease, thereby lengthening the flexible belt 10 between the release roller 21 and the winding roller 22. When the drive roller 30 moves in a direction away from the flexible belt 10, the control element controls the rotational speed of the release roller 21 to decrease and / or controls the rotational speed of the winding roller 22 to increase, thereby shortening the flexible belt 10 between the release roller 21 and the winding roller 22.

[0060] The film-tearing device provided in this embodiment drives the drive roller 30 to move in a direction close to or away from the flexible belt 10 via a drive member and connecting arm 31, thereby driving the flexible belt 10 to move in a direction close to or away from the film 101. This ensures that during film tearing, the drive roller 30 drives the flexible belt 10 closer to the film 101, and during display module loading and unloading, the drive roller 30 drives the flexible belt 10 away from the film 101, achieving continuous loading of display modules and thus improving film tearing efficiency and display module production efficiency.

[0061] Please refer to Figure 1 , Figures 3 to 7 , Figure 6 Fifth schematic diagram of the main structure of another example of a film-tearing device; Figure 7 The sixth example shows a front view of a film-tearing device.

[0062] like Figure 1 , Figures 3 to 7 As shown, in some optional embodiments, the drive member is used to drive the connecting arm 31 to drive the drive roller 30 to reciprocate between the release roller 21 and the winding roller 22.

[0063] Optionally, the line connecting the release roller 21 and the winding roller 22 is parallel to the first direction x. The driving member drives the connecting arm 31 to move the driving roller along the first direction x, thereby causing the flexible belt 10 to contact different positions of the film 101. For example, the film 101 includes a wiping section 1011 and a non-wiping section 1012, which are arranged along the first direction x. Figure 5 As shown, when the cleaning section 11 contacts the film 101, the orthographic projection of the rotation axis of the drive roller 30 onto the film 101 is located at the center of the wiping section 1011, so that the wiping range of the cleaning section 11 on the film 101 covers the wiping section 1011. Figure 6 As shown, when the flexible strip 10 changes from contact between the cleaning section 11 and the film 101 to contact between the adhesive section 12 and the film 101, the drive roller 30 moves along the first direction x until the orthographic projection of the rotation axis of the drive roller 30 on the screen body 100 overlaps with the orthographic projection of the end of the wiping section 1011 on the side away from the non-wiping section 1012 on the screen body 100. The adhesive section 12 then angles the edge of the film 101 and sticks it away from the screen body 100 to complete the film removal.

[0064] Optionally, the contact between the cleaning section 11 and the film 101 is defined as the cleaning stage, and the contact between the adhesive section and the film 101 is defined as the adhesive stage. The cleaning stage and the adhesive stage together constitute a complete film-peeling process. When the drive mechanism drives the flexible belt 10 from the cleaning stage to the adhesive stage, the drive component first drives the drive roller 30 and the flexible belt 10 away from the film 101 along the second direction y, so that the flexible belt 10 separates from the film 101, as shown below. Figure 1 As shown. Then, the driving member drives the driving roller 30 to move along the first direction x until the orthographic projection of the rotation axis of the driving roller 30 on the screen 100 overlaps with the orthographic projection of the end of the wiping section 1011 on the side opposite to the non-wiping section 1012 on the screen 100. Then, the driving member drives the driving roller 30 and the flexible belt 10 to approach the film 101 along the second direction y, as shown. Figure 4 and Figure 6 As shown. During the pasting stage, the winding roller 22 rotates and winds the pasting section 12 with the film 101 pasted on it together with the film 101 and collects it onto the winding roller 22, as shown. Figure 7 As shown.

[0065] The film-removing device provided in this embodiment drives the connecting arm 31 via a driving component to move the driving roller 30 back and forth along the line connecting the release roller 21 and the winding roller 22. This aligns the driving roller 30 with the center of the wiping section 1011 during the cleaning phase, increasing the wiping range of the cleaning section 11 on the film 101 and thus improving the cleaning effect of the cleaning section 11 on the film 101. During the transition from the cleaning phase to the pasting phase, the orthographic projection of the rotation axis of the driving roller 30 on the screen 100 overlaps with the orthographic projection of the end of the wiping section 1011 on the side away from the non-wiping section 1012 on the screen 100. This causes the edge of the pasting section 12 to contact the edge of the wiping section 1011, improving the pasting effect of the pasting section 12 on the film 101, reducing the probability of film peeling off, and thus improving the film-removing efficiency and the yield rate of the display module.

[0066] In some optional embodiments, a drive member is connected to the release roller 21 to drive the release roller 21 to move along a first direction x and a second direction y. A control member is connected to the release roller 21 and / or the winding roller 22, and the control member is used to control the rotational speed of the release roller 21 and / or the winding roller 22. When the flexible tape 10 is in the cleaning stage or the pasting stage, the drive member drives the release roller 21 to move closer to the film 101 along the second direction y, and the control member controls the rotational speed of the release roller 21 to increase and / or controls the rotational speed of the winding roller 22 to decrease, thereby lengthening the flexible tape 10 between the release roller 21 and the winding roller 22. When the flexible tape 10 transitions between the cleaning stage and the pasting stage, the drive member drives the release roller 21 to move away from the film 101 along the second direction y, or the drive member drives the release roller 21 to move along the first direction x, and the control member controls the rotational speed of the release roller 21 to decrease and / or controls the rotational speed of the winding roller 22 to increase, thereby shortening the flexible tape 10 between the release roller 21 and the winding roller 22.

[0067] The film-tearing device provided in this embodiment replaces the function of the drive roller 30 with the release roller 21, which simplifies the structure of the film-tearing device and reduces the manufacturing cost of the film-tearing device.

[0068] Please refer to Figure 8 , Figure 8 The seventh is a schematic diagram of the main structure of another example of a film-tearing device.

[0069] like Figure 8 As shown, in some optional embodiments, the film-tearing device may further include a liquid storage tank 40 containing cleaning fluid (not shown), which is used to inject cleaning fluid into the cleaning section 11.

[0070] Optionally, the cleaning solution can be distilled water or alcohol.

[0071] The film-tearing device provided in this embodiment improves the cleaning effect of the cleaning section 11 on the film 101 by using the liquid storage tank 40 and the cleaning liquid contained in the liquid storage tank 40.

[0072] In some alternative embodiments, the film-tearing device may further include a conduit 50 communicating with the liquid storage tank 40 and the drive roller 30, and / or, the conduit 50 communicating with the liquid storage tank 40 and the release roller 21.

[0073] Optionally, at least a portion of the conduit 50 is located inside the connecting arm 31. The conduit 50 is equipped with a valve (not shown) to control the opening and closing of the conduit 50 and the flow rate of the liquid. For example, when the flexible strip 10 is in the cleaning stage, the valve opens, allowing cleaning fluid to flow from the reservoir 40 and wet the cleaning section 11, improving the cleaning effect of the cleaning section 11 on the membrane 101. When the flexible strip 10 is in the bonding stage, the valve closes, preventing the cleaning fluid in the reservoir 40 from flowing out.

[0074] In some alternative embodiments, the surfaces of the drive roller 30 and / or release roller 21 are provided with openings (not shown) that communicate with the liquid outlet end of the conduit 50.

[0075] The film-peeling device provided in this embodiment reduces the difficulty of arranging the conduit 50 by accommodating part of the conduit 50 inside the connecting arm 31. By arranging the liquid outlet end of the conduit 50 on the surface of the drive roller 30 and / or release roller 21, the cleaning liquid flows directly from the liquid outlet end of the conduit 50 and wets the cleaning section 11 during the movement of the flexible belt 10, thereby improving the cleaning effect of the cleaning section 11 on the film 101. Through the valve provided on the conduit 50, the cleaning liquid in the storage tank 40 only flows out and wets the cleaning section 11 during the cleaning stage, and does not flow out during the pasting stage to avoid the cleaning liquid affecting the pasting effect of the pasting section 12 on the film 101.

[0076] In some optional embodiments, the film-tearing device further includes a platform 60 for supporting the screen 100, a film 101 connected to the side of the screen 100 away from the platform 60, and a flexible strip 10 located on the side of the film 101 away from the screen 100.

[0077] In some alternative embodiments, the film-tearing device further includes a housing (not shown) and a vacuum pump (not shown) connected to the housing. The housing has a receiving cavity in which the flexible belt 10, the drive mechanism 20 and the stage 60 are all housed. The vacuum pump is used to evacuate the receiving cavity.

[0078] Optionally, the release roller 21 and the winding roller 22 are fixed to the housing and can rotate relative to the housing about their respective axes.

[0079] The film-peeling device provided in this embodiment uses a vacuum pump to evacuate the receiving cavity during the film-peeling process, thereby reducing the impact of environmental pollutants on the adhesiveness of the adhesive segment 12 and improving the effect of the adhesive segment 12 on the adhesive film 101.

[0080] In summary, the film-removing device provided in this embodiment includes a flexible strip 10 and a driving mechanism 20. The flexible strip 10 extends along a preset path and includes a cleaning section 11 and an adhesive section 12 arranged along the preset path. The driving mechanism 20 is connected to the flexible strip 10 and is used to drive the flexible strip 10 to move along the preset path. During the movement of the flexible strip 10, the cleaning section 11 in the flexible strip 10 wipes the surface of the film 101 to remove dirt from the surface of the film 101. Then, the driving mechanism 20 continues to drive the flexible strip 10 to move, so that the adhesive section 12 adheres to the film 101 and peels the film 101 off the screen 100. By cleaning the surface of the film 101 with the cleaning section 11 before adhesion, the adhesion effect of the adhesive section 12 on the film 101 is improved, the probability of film peeling off is reduced, and thus the film-removing efficiency and the yield rate of the display module are improved.
