[0035] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0036] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0037] See also Figure 1 The embodiment of the present application discloses an automatic feeding mechanism for a PU protective film, comprising: a fixing part 10, a feeding assembly 20, and a feeding assembly 30. The fixing part 10 is located on the sides of the feeding assembly 20 and the feeding assembly 30, and the feeding assembly 20 and the feeding assembly 30 are fixed on the fixing part 10. The feeding assembly 20 is used to hang a sticking part 23 on the fixing part 10 and extend the sticking part 23. The feeding assembly 30 is used to accommodate a protective film (that is, a PU protective film), and the sticking part 23 is used to bond the protective film to realize the feeding of the protective film.

[0038] The unloading assembly 20 includes an unloading rod 21 and a guide rod 22. The unloading rod 21 is used to hang the adhesive piece 23 for bonding the protective film, which can be understood as an adhesive tape. The adhesive surface of the adhesive piece 23 is wound on the guide rod 22, with the adhesive surface facing outward for bonding the protective film. There are multiple guide rods 22, which can be used for the extended adhesive piece 23 to be wound and play a guiding role during winding. It is explained here that the head end of the adhesive piece 23 is pulled and rolled back by another process, so it will drive the adhesive piece 23 to move on the guide rod 22, realizing the automatic rotation of the adhesive piece 23.

[0039] In order to realize automatic loading of the protective film, the loading component 30 includes a loading movable part 31 and a loading driving part. The loading movable part 31 contains the protective film, and the loading driving part is electrically connected to the loading movable part 31, so that the loading movable part 31 is driven by the loading driving part to reciprocate relative to the unloading component 20, so that the adhesive part 23 can adhere to the protective film, and cooperate with the rewinding movement of the adhesive part 23 in the next process to realize automatic loading of the protective film, that is, to realize the loading of the protective film to the display module.

[0040] Specifically, a first moving member 32, a first adjusting member 33, a second moving member 34 and a second adjusting member 35 are provided on the feeding moving member 31. The first adjusting member 33 and the second adjusting member 35 are as shown in FIG. Figure 1 The threaded member shown in . The first movable member 32 and the second movable member 34 are two panels, and a accommodating space for accommodating the protective film is formed around the loading movable member 31. The first adjusting member 33 is connected to the first movable member 32, and is used to adjust the position of the first movable member 32 on the loading movable member 31, that is, to adjust the width of the accommodating protective film. The second adjusting member 35 is connected to the second movable member 34, and is used to adjust the position of the second movable member 34 on the loading movable member 31, that is, to adjust the length of the accommodating protective film. In this way, the size of the formed accommodating space can be adjusted to accommodate protective films of different sizes, and then it can adapt to PU protective films of different sizes for automatic loading, and the structure is simple, so that the investment cost is low.

[0041] In addition, in order to facilitate the adjustment of the positions of the first movable member 32 and the second movable member 34 so as to adapt to protective films of different sizes, a through hole 321 is further provided on the first movable member 32 , and the second movable member 34 abuts against the protective film accommodated in the accommodation space through the through hole 321 .

[0042] Furthermore, in order to facilitate the adhesive member 23 to adhere to the protective film, in the present embodiment, a material taking port 36 is provided at one end of the loading movable member 31 close to the discharge rod 21, and the material taking port 36 is communicated with the accommodating space; the discharge assembly 20 also includes an abutment block 24, which is arranged relative to the material taking port 36, and the adhesive member 23 moves through the guide rod 22 to cover the surface of the abutment block 24.

[0043] When feeding, when the feeding moving member 31 moves close to the abutting block 24 based on the driving of the feeding driving member, the abutting block 24 is embedded in the material taking port 36, and at the same time, one side of the adhesive member 23 abuts against the abutting block 24, and the other side adheres to the protective film located in the accommodating space; when the feeding moving member 31 moves away from the abutting block 24 based on the driving of the feeding driving member, the material taking port 36 is away from the adhesive member 23 with the protective film adhered. In this way, the feeding moving member 31 can be driven by the feeding driving member to reciprocate relative to the material discharging assembly 20 to achieve sequential adhesion of the protective film.

[0044] In order to facilitate the adjustment of the positions of the first movable member 32 and the second movable member 34 , in this embodiment, a first adjustment hole 311 is provided on the loading movable member 31 corresponding to the first adjustment member 33 , and a second adjustment hole 312 is provided on the loading movable member 31 corresponding to the second adjustment member 35 .

[0045] The shapes of the first adjustment hole 311 and the second adjustment hole 312 can be as follows: Figure 1 As shown, during adjustment, the first adjusting member 33 moves linearly on the first adjusting hole 311, thereby driving the first moving member 32 to move, and when it moves to a certain position, it can be fixed by screwing the first adjusting member 33. Similarly, the second adjusting member 35 moves linearly on the second adjusting hole 312, thereby driving the second moving member 34 to move, and when it moves to a certain position, it can be fixed by screwing the second adjusting member 35. In this way, the size of the accommodating space can be flexibly adjusted to suit protective films of different sizes.

[0046] In order to avoid multiple protective films being adhered to the adhesive member 23, resulting in waste of protective films and affecting the product quality of the display module, in this embodiment, a blowing member 40 is further provided, one end of the blowing member 40 is fixed to the fixing member 10, and the other end is provided with an air nozzle 41, which is arranged above the abutment block 24.

[0047] In order to better play the role of the air nozzle 41, the air nozzle 41 can be set to a flat mouth shape, so as to accurately blow the protective film and increase the intensity of the blowing. In order to facilitate the movement of the position of the air nozzle 41, the blowing member 40 can be set as a movable connecting rod, so that the operator can manually twist the connecting rod of the blowing member 40 to flexibly adjust the position of the air nozzle 41.

[0048] In addition, in this embodiment, a plurality of guide rods 22 are provided, and their positions can be as follows: Figure 1 As shown in the figure, one of the guide rods 22 is arranged above the abutment block 24, so that the adhesive member 23 can cover the abutment block 24, and one guide rod 22 is arranged below the loading moving member 31 relative to the air nozzle 41, which can facilitate the discharge of the protective film for conveying to the next process.

[0049] In summary, an automatic feeding mechanism for PU protective film disclosed in an embodiment of the present application has a discharge rod 21 that can be used to hang an adhesive member 23 for bonding the protective film, and a guide rod 22 that can be used for winding the extended adhesive member 23 to play a guiding role, and then cooperates with the feeding drive member to drive the feeding movable member 31 to reciprocate toward the discharge component 20, which can facilitate the adhesive member 23 to bond the protective film placed in the feeding movable member 31, thereby realizing the feeding of the protective film; a first moving member 32, a first adjusting member 33, a second moving member 34 and a second adjusting member 35 are arranged on the feeding movable member 31 to adjust the formed accommodating space to accommodate protective films of different sizes, so that the present application can adapt to automatic feeding of PU protective films of different sizes, and has a simple structure, so that the investment cost is relatively low.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
