The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0029] See Figure 1 , embodiments of the present disclosure provide a film pasting mold, which includes a bottom plate 1, a first clamping portion, and a second clamping portion; the first clamping portion is used to clamp a film body 15 in a first direction, the first clamping portion includes a first clamp 2, the first clamp 2 is disposed on the bottom plate 1, and the first clamp 2 is movably disposed in the first direction; the second clamping portion is used to clamp the film body 15 in a second direction, the second clamping portion includes a second clamp 3, the second clamp 3 is disposed on the bottom plate 1, and the second clamp 3 is movably disposed in the second direction; wherein, the first direction is perpendicular to the second direction, and the first clamp 2 and the second clamp 3 approach or separate from each other so that the first clamp 2 and the second clamp 3 form a film frame with adjustable size.

[0030] In this embodiment, the first direction and the second direction refer to that, with the upper surface of the bottom plate 1 as the projection plane, the first direction is the vertical direction and the second direction is the horizontal direction.

[0031] The side of the film body 15 without the glue layer (i.e., the smooth surface) faces the first fixture 2 and the second fixture 3. According to the size of the film body 15, the first fixture 2 moves a certain distance in the first direction so that the first fixture 2 holds or abuts against one or both sides of the film body 15; the second fixture 3 moves a certain distance in the second direction so that the second fixture 3 holds or abuts against one or both sides of the film body 15. At this time, the first fixture 2 and the second fixture 3 fix at least two sides of the film body 15. The film body 15 is placed with its smooth surface facing downwards and the side with the glue layer facing upwards. At this time, the mask plate is placed on the film body 15 so that the glue layer of the film body 15 is attached to the mask plate. Then, both hands press down the mask plate vertically with force at the same time. After the film pasting is completed, the mask plate is taken out from the film pasting mold. If it is necessary to replace the film body 15 with a different size, the first fixture 2 and the second fixture 3 are moved again, and the above steps are repeated to adjust the relative size of the film frame.

[0032] In this embodiment, compared with the film pasting mold with a fixed-size film frame, this embodiment is provided with a film frame formed by two fixtures. Through the movable first fixture 2 and second fixture 3, and the moving directions of the first fixture 2 and the second fixture 3 are different, the change of the film frame size can be realized. Even if the size of the film body 15 changes, the size of the film frame can be adjusted by moving the fixtures, thereby realizing the switching of the film frame, simplifying the operation steps, improving the work efficiency, reducing the cost of the film pasting mold, and solving the problem in the prior art that for different protective films, the sizes of the film frames used are different, and different-sized film frames need to be replaced, resulting in an increase in the number of film pasting molds.

[0033] In addition to being able to clamp the film body 15, the first fixture 2 and the second fixture 3 of this embodiment have support rods extending in the first direction, which are used to support one side of the film body 15, and the second fixture 3 has support rods extending in the second direction, which are used to support the other side of the film body 15. In this way, the fixation of the four sides of the film body 15 can be realized.

[0034] In this embodiment, the film body 15 can be square or rectangular, and the change of the film frame size can also be realized by adjusting the first fixture 2 and the second fixture 3.

[0035] The bottom plate 1 serves as a support platform. The first clamping part and the second clamping part use the bottom plate 1 as the platform, so that the first fixture 2 and the second fixture 3 can move on the bottom plate 1 to form a film frame. The area of the bottom plate 1 is large enough to meet the placement requirements of the film body 15 and the movement requirements of the fixtures. The center of the film body 15 is the center of the bottom plate 1, and the first fixture 2 and the second fixture 3 respectively move towards the geometric center of the bottom plate 1.

[0036] See Figure 1 , in some embodiments, the first clamping portion further includes a first motor 4, and an output shaft of the first motor 4 is connected to a side wall of the first fixture 2 facing away from the step structure 8; the second clamping portion further includes a second motor 5, and an output shaft of the second motor 5 is connected to a side wall of the second fixture 3 facing away from the step structure 8.

[0037] When it is necessary to move the first fixture 2, the output shaft of the first motor 4 extends or contracts. When it is necessary to move the second fixture 3, the output shaft of the second motor 5 extends or retracts. In this way, linear movement of the first fixture 2 and the second fixture 3 can be achieved. If the output shafts of both the first motor 4 and the second motor 5 extend, it means that the first fixture 2 and the second fixture 3 are approaching each other, and at this time, the size of the membrane frame is reduced; if the output shafts of both the first motor 4 and the second motor 5 retract, it means that the first fixture 2 and the second fixture 3 are moving away from each other, and at this time, the size of the membrane frame is increased.

[0038] Of course, motors may not be provided. Instead, slide rails are respectively provided on the bottom plate 1 in the first direction and the second direction. The first fixture 2 and the second fixture 3 can slide along the slide rails. After the first fixture 2 and the second fixture 3 are moved in place, the fixtures are fixed to the base using bolts respectively.

[0039] In this embodiment, the first fixture 2 and the second fixture 3 can be moved either electrically or manually. Preferably, the first motor 4 and the second motor 5 are provided. This can save labor, and the moving distance can be adjusted more precisely through the motors, avoiding repeated adjustment of the first fixture 2 and the second fixture 3.

[0040] See Figure 1 , in some embodiments, the first clamping portion further includes a third fixture 6. The third fixture 6 is symmetrically arranged with the first fixture 2. The third fixture 6 is arranged on the bottom plate 1 and is movably arranged in the first direction. The first fixture 2 and the third fixture 6 approach or move away from each other in the first direction, so that a membrane frame with an adjustable size is formed from the first fixture 2 to the third fixture 6.

[0041] In this embodiment, when the membrane body 15 is rectangular, compared with the arrangement of two fixtures, this embodiment further provides a third fixture 6. The long side dimension of the membrane body 15 is relatively long. The first fixture 2 and the third fixture 6 respectively clamp two short sides of the membrane body 15, that is, the long side of the membrane body 15 is better supported, avoiding the long side of the membrane body 15 from warping. For the short side of the membrane body 15, only one second fixture 3 is provided to clamp the long side of the membrane body 15. In this embodiment, providing the third fixture 6 can provide better supporting force and avoid the long side of the membrane body 15 from warping.

[0042] See Figure 1In some embodiments, the second clamping portion further includes a fourth clamp 7, which is symmetrically arranged with the second clamp 3, and the fourth clamp 7 is arranged on the base plate 1. The fourth clamp 7 is movably arranged in the second direction, and the second clamp 3 and the fourth clamp 7 are close to or away from each other in the second direction, so that the first clamp 2 to the fourth clamp 7 form a film frame with adjustable size.

[0043] In this embodiment, according to the size of the film body 15, the first clamp 2 to the fourth clamp 7 are moved respectively, and the four clamps are combined to form a quadrilateral film frame. This arrangement can use rectangular or positive-direction film bodies 15 of different sizes, and the clamping force on the four sides of the film body 15 is more uniform. When the mask plate is pressed to fit the film body 15, the four sides of the film body 15 can be evenly applied, and the use range of the film-sticking mold is greatly expanded.

[0044] In some examples, the first clamping part further includes a third motor, and the second clamping part further includes a fourth motor. The third motor and the fourth motor are respectively connected to the third clamp 6 and the fourth clamp 7, that is, all four clamps are moved electrically.

[0045] See also Figure 1 and Figure 2 In some embodiments, the first clamp 2 to the fourth clamp 7 are respectively provided with a step structure 8, and the step structure 8 has a bottom surface and a side surface, the bottom surface contacts the surface of the film body 15 facing away from the adhesive layer, and the side surface abuts the side wall of the film body 15.

[0046] The first clamp 2 to the fourth clamp 7 refer to the first clamp 2 , the second clamp 3 , the third clamp 6 and the fourth clamp 7 .

[0047] Taking into account the two surfaces of the film body 15, one side has a glue layer and the other side is smooth, and the film body 15 needs to be taken out of the film frame after being attached to the mask, the first clamp 2 to the fourth clamp 7 of this embodiment are respectively provided with step structures 8, so that after the film body 15 is placed in the film frame, the side walls of the four step structures 8 are respectively abutted against the four edges of the film body 15, which is equivalent to the film body 15 being laid flat in the entire film frame, and the clamp does not clamp the outer edge of the film body 15.

[0048] In this embodiment, considering the bonding method and removal method of the film body 15 and the mask, the step structure 8 is provided to facilitate the removal of the mask from the film frame after the film bonding is completed, and in the process of pressing the mask, the mask can be more bonded to the film body 15. In addition, the appearance of the film body 15 will not be damaged, thereby ensuring the flatness of the film body 15.

[0049] In some examples, the side surfaces of the four step structures 8 have the same height, so as to better fit with the film body 15 and clamp the film body 15 from four directions.

[0050] Of course, the fixture may not be provided with a stepped surface, but instead be provided with a suction nozzle, and the film body 15 is adsorbed by the adsorption force generated by the suction nozzle.

[0051] In some embodiments, the first fixture 2 and the second fixture 3 are L-shaped, and the first fixture 2 and the second fixture 3 are diagonally arranged on the bottom plate 1. The long sides of the first fixture 2 and the second fixture 3 are respectively abutted against two sides of the film body 15, and the short sides of the first fixture 2 and the second fixture 3 are respectively abutted against the other two sides of the film body 15.

[0052] The first fixture 2 and the second fixture 3 are diagonally arranged, and the two fixtures are respectively L-shaped. In this way, after the first fixture 2 moves into place, the first fixture 2 can clamp two sides of the film body 15. After the second fixture 3 moves into place, the second fixture 3 can clamp the other two sides of the film body 15.

[0053] In this embodiment, moving one fixture at a time can fix two sides of the film body 15, simplifying the overall structure and making it more convenient to use. At the same time, it can ensure that the size of the film frame can still be adjusted. Of course, the first fixture 2 and the second fixture 3 can also be moved simultaneously, and the moving distances of the first fixture 2 and the second fixture 3 are equal, so that the first fixture 2 and the second fixture 3 contact the film body 15 at the same time, that is, clamp the film body 15 at the same time; thus avoiding the relative movement of the film body 15 with respect to the film frame, that is, the center of the film body 15 remains unchanged relative to the position of the positioning post, ensuring the relative position of the film frame and the film body 15 remains unchanged.

[0054] In some examples, the first fixture 2 and the second fixture 3 of this structure are also provided with a stepped structure 8, and the long sides and short sides of the first fixture 2 and the second fixture 3 are respectively abutted against the four sides of the film body 15.

[0055] See Figure 1 , in some embodiments, a first infrared emitter 9 and a second infrared emitter 10 are provided on the bottom plate 1. The first infrared emitter 9 is located on the moving path of the first fixture 2, and the second infrared emitter 10 is located on the moving path of the second fixture 3.

[0056] In this embodiment, during the movement of the first fixture 2, the first infrared emitter 9 is used to detect the displacement distance of the first fixture 2, and the second infrared emitter 10 is used to detect the displacement distance of the second fixture 3. In this way, the moving length of the fixture can be more accurately understood, facilitating the adjustment of the displacement distance of each fixture, and thus accurately adjusting the size of the film frame.

[0057] In some examples, when the first clamping part further includes a third clamp 6 and the second clamping part further includes a fourth clamp 7, a third infrared emitter and a fourth infrared emitter are arranged on the bottom plate 1. The third infrared emitter is located on the moving path of the third clamp 6, and the fourth infrared emitter is located on the moving path of the fourth clamp 7. Considering that all four clamps can move, infrared emitters are set for different clamps, which can more accurately obtain the moving lengths of each clamp.

[0058] See Figure 1 , in some embodiments, in the first direction, a plurality of first positioning posts 11 are arranged on the bottom plate 1, and in the second direction, a plurality of second positioning posts 12 are arranged on the bottom plate 1. The first positioning posts 11 and the second positioning posts 12 are respectively located outside the film frame, and the first positioning posts 11 and the second positioning posts 12 are respectively used for positioning the outer edges of the mask plate.

[0059] Adjust the positions of the first clamp 2 and the second clamp 3, place the light surface of the film body 15 downward and the surface with the adhesive layer of the film body 15 upward. At this time, first align the mask plate above the film body 15, make one side of the mask plate abut against the first positioning post 11, for example, the long side of the mask plate, and make the other side of the mask plate abut against the second positioning post 12, for example, the short side of the mask plate. At this time, the positions of at least two sides of the mask plate are fixed. Then, press the mask plate vertically downward with both hands at the same time, and the mask plate slides along the outer walls of the first positioning post 11 and the second positioning post 12.

[0060] In this embodiment, by setting the first clamp 2 and the second clamp 3, the film body 15 can be clamped, and at the same time, by setting the first positioning post 11 and the second positioning post 12, the mask plate can be made to slide directionally, so that the mask plate fits the film body 15 more precisely.

[0061] In some examples, a plurality of mounting holes at different positions can be arranged on the bottom plate 1. After replacing the film body 15 of different sizes, the mounting positions of the first positioning post 11 and the second positioning post 12 can be flexibly adjusted according to the size of the mask plate.

[0062] See Figure 1 , in some embodiments, in the first direction, at least two first contact sensors 13 are arranged on the bottom plate 1, and in the second direction, at least two second contact sensors 14 are arranged on the bottom plate 1. The first contact sensors 13 and the second contact sensors 14 are respectively located outside the film frame, and at least two first contact sensors 13 and second contact sensors 14 are respectively in contact with the four corners of the mask plate.

[0063] In this embodiment, when the mask plate slides along the first positioning post 11 and the second positioning post 12, press the mask plate vertically downward with both hands simultaneously until the four corners of the mask plate are in contact with the contact sensors respectively, indicating that the mask plate is pressed in place and the film body 15 is already attached to the mask plate, and then remove the mask plate from the film frame. By setting the contact sensors in this embodiment, the attachment condition of the film body 15 and the mask plate can be judged more accurately, avoiding repeatedly pressing the mask plate when the attachment is not in place.

[0064] In some examples, an alarm electrically connected to the contact sensors is provided on the bottom plate 1, and when the film body 15 is attached to the mask plate in place, the alarm will emit a prompt sound.

[0065] See Figure 1 , in some embodiments, taking the longitudinal section of the bottom plate 1 as the projection plane, the heights of the first positioning post 11, the second positioning post 12, the first contact sensor 13 and the second contact sensor 14 are all higher than those of the first fixture 2 and the second fixture 3.

[0066] In this embodiment, since the mask plate has to slide along the first positioning post 11 and the second positioning post 12, the first positioning post 11 and the second positioning post 12 need to have a certain length to play a guiding role. Considering that the mask plate has a certain thickness, the thickness of the contact sensors is also higher than that of the fixtures.

[0067] The above are only the implementation manners of the present application, and do not limit the patent protection scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
