[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figures 1 to 7 As shown, this embodiment shows a film stripping and adsorption device, comprising: an operating platform assembly 10, a roller assembly 20, an interlayer stripping assembly 30, and an adsorption assembly 40. The operating platform assembly 10 includes a base structure 11 and an operating platform structure 12, with the operating platform structure 12 disposed on the base structure 11. The roller assembly 20 includes a roller structure 21, a first winding roller structure 22, and a second winding roller structure 23. The roller structure 21, the first winding roller structure 22, and the second winding roller structure 23 are rotatably mounted on the base structure 11, with the first winding roller structure 22 and the second winding roller structure 23 located on either side of the roller structure 21 and the operating platform structure 12, respectively. The interlayer stripping assembly 30 is disposed above the operating platform structure 12. The adsorption assembly 40 includes a negative pressure drive structure and a negative pressure shell structure 41. The negative pressure drive structure is fixed on the operating platform structure 12. The negative pressure shell structure 41 is movably arranged on the operating platform structure 12. The negative pressure shell structure 41 has a first adsorption channel 411. The outlet of the first adsorption channel 411 is located on the side of the negative pressure shell structure 41 away from the operating platform structure 12. The inlet of the first adsorption channel 411 is located on the side close to the operating platform structure 12. The first adsorption channel 411 is inclined toward the direction close to the roller structure 21.

[0034] Through the above technical solution, the film stripping and adsorption device provided by the present application releases the film structure through the roller structure 21, the first winding roller structure 22 recovers the covering film 200, the second winding roller structure 23 recovers the bottom film 300, and the adsorption component 40 adsorbs the film. The first adsorption channel 411 is inclined in the direction close to the roller structure 21 (in fact, it is in the direction of the film, so that the edge of the film 100 is adsorbed as much as possible), so that the adsorption of the film 100 is relatively close to the edge. In this way, when the film is applied again through the adsorption component 40, it is not easy to form wrinkles, bubbles and other undesirable conditions. In addition, by providing the intervening stripping component 30, the separation effect of the covering film 200 and the film 100 is better. The technical solution of this embodiment effectively solves the problem that the film stripping and adsorption device in the prior art is not easy to form wrinkles, bubbles and other undesirable conditions when applying the film.

[0035] like Figures 4 to 6 As shown, in the technical solution of this embodiment, the negative pressure housing structure 41 includes a negative pressure seat and a sealing cover that seals with the negative pressure seat. The negative pressure housing structure 41 is provided with a total negative pressure channel, and the negative pressure seat is provided with a negative pressure groove 412. The first port of the total negative pressure channel is provided on the outer wall of the negative pressure housing structure 41, and the second port of the total negative pressure channel is connected to the negative pressure groove 412. The first adsorption channel 411 is connected to the negative pressure groove 412. The provision of the negative pressure groove 412 can provide a certain buffering capacity, making the adsorption pressure more stable.

[0036] like Figures 4 to 6 As shown, in the technical solution of this embodiment, the width of the negative pressure seat is adapted to the width of the film, and a plurality of first adsorption channels 411 are provided along the width direction of the negative pressure seat. The plurality of first adsorption channels 411 makes the adsorption area of ​​the membrane 100 larger. It should be noted that the first adsorption channels 411 are arranged in parallel, and the negative pressure adsorption force is relatively balanced. The inclination angle of the first adsorption channel 411 is between 20° and 70°, and the above-mentioned inclination angle is the angle between the first adsorption channel 411 and the horizontal plane. The above-mentioned first adsorption channel 411 extends to the edge as much as possible.

[0037] like Figure 6 As shown, in the technical solution of this embodiment, the negative pressure housing structure 41 is further provided with a plurality of second adsorption channels 415, the first port of each second adsorption channel 415 is connected to the negative pressure groove 412, and the second port of each second adsorption channel 415 is provided on the side of the negative pressure housing structure 41 facing the operating platform structure 12. The provision of the second adsorption channel 415 makes the negative pressure housing structure 41 have a larger adsorption area for the membrane 100. It should be noted that the second adsorption channel 415 of this embodiment is not limited to Figure 6 The first adsorption channels 411 are arranged in a row, and the second adsorption channels 415 are arranged in multiple rows and columns. The second ports of adjacent first adsorption channels 411 and second adsorption channels 415 are spaced equally apart, and the second ports of adjacent second adsorption channels 415 are spaced equally apart. This ensures that the adsorption force of the negative pressure housing structure 41 on the membrane 100 is relatively balanced.

[0038] like Figure 5 and Figure 6As shown, in the technical solution of this embodiment, the negative pressure seat includes a seat body 413 and a pressure block 414. The pressure block 414 is arranged on the side of the seat body 413 facing the roller structure 21. The side of the pressure block 414 facing the operating platform structure 12 is flush with the side of the pressure block 414 facing the operating platform structure 12. The side of the pressure block 414 away from the operating platform structure 12 is lower than the side of the seat body 413 away from the operating platform structure 12. The above structure allows the pressure roller and the pressure block 414 to cooperate better when the film 100 is attached, and the area of ​​the film 100 pressed together by the pressure roller and the pressure block 414 is larger. It should be noted that the pressure block 414 and the seat body 413 of this embodiment are an integrally formed structure, and the second port of the first adsorption channel 411 is located on the bottom surface of the pressure block 414. As other embodiments, the pressure block 414 and the seat body 413 can also be split structures and connected together.

[0039] like Figure 5 and Figure 6 As shown, in the technical solution of this embodiment, in a cross-section along the width direction of the negative pressure seat, the side of the pressure block 414 away from the operating platform structure 12 is arc-shaped. The arc-shaped structure is more easily matched with the pressure roller. During film application, the negative pressure housing structure 41 applies the film, and the pressure roller behind it rolls the film 100. This can expel bubbles between the film 100 and the object being applied, and facilitate the adhesion of the film 100 to the object being applied. It should be noted that the arc in this embodiment is a circular arc, and the diameter of the arc is compatible with the diameter of the roller used for rolling.

[0040] like Figure 3 As shown, in the technical solution of this embodiment, the intervention stripping assembly 30 includes an intervention block, which is arranged on the base structure 11 and located on the upper part of the operating platform structure 12. The intervention block spans the width of the operating platform structure 12 and is located between the two ends of the operating platform structure 12. The arrangement of the intervention block is simple in structure and improves the separation of the film 100 and the cover film 200.

[0041] like Figure 3 As shown, in the technical solution of this embodiment, the intervention block has a contraction section at the end away from the roller structure 21. The thickness of the contraction section gradually decreases as it approaches the roller structure 21 and moves away from it. This structure facilitates the separation of the film 100 from the cover film 200. For thin or ultra-thin films, the cover film 200 easily carries the film 100 to the first winding roller structure 22. The provision of the contraction section further improves the success rate of separating the cover film 200 from the film 100. It should be noted that the contraction section has a downward inclination angle.

[0042] like Figures 1 to 3As shown, in the technical solution of this embodiment, the roller assembly 20 further includes a guide roller structure 24, which is arranged on the upper part of the operating platform structure 12 and between the intervention block and the roller structure 21. The bottom ring of the guide roller structure 24 of the above structure is tangent to the plane of the operating platform structure 12, so that the membrane structure is horizontal after passing through the guide roller structure 24.

[0043] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the winding roller assembly 20 also includes a step-by-step pinch roller structure 25, and the step-by-step pinch roller structure 25 is arranged at the lower part of the operating platform structure 12. The step-by-step pinch roller structure 25 is two rollers, and the bottom film 300 is squeezed by the two rollers. It should be noted that the second winding roller structure 23 maintains tension, but the tension should not be too large (not greater than the force that destroys the bottom film 300). After the adsorption component 40 and the film 100 are adsorbed, the adsorption component 40 retreats, driving the film 100 and the bottom film 300 to move forward. Figure 2 The bottom film 300 is moved to the left side in the middle, so that the bottom film 300 in a tension state is rolled into the second winding roller structure.
