Vacuum attachment platform for flexible film

Abstract

The invention discloses a vacuum attachment platform for a flexible film. The vacuum attachment platform comprises a machine table, a second adsorption platform and a movable base. The machine table is provided with an adsorption platform for adsorbing the flexible film, and a hollow operation area is formed in the bottom of the adsorption platform. The second adsorption platform is located abovethe machine table, and is provided with a suction surface which is used for adsorbing a preset sheet to which the flexible film is attached and opposite to the machine table. The movable base is located below the operation area of the adsorption platform of the machine table, and is provided with an abutment part which performs lifting displacement in the operation area to abut and hold the lifting and lowering of the adsorption platform to attach the flexible film to the surface of the preset sheet. The vacuum attachment platform for the flexible film enables the flexible film to be smoothlyattached to the surface of the sheet through static electricity generated by the adsorption platform, the film can be completely attached to the surface of the sheet without being in a vacuum workingenvironment, and the purpose of no damage to the film is achieved.

Description

technical field [0001] The invention relates to an automatic film attaching device, in particular to a vacuum attaching platform for a flexible film. Background technique [0002] At present, with the continuous upgrading of electronic products, consumers' dependence on and demand for electronic products is also increasing. The current manufacturing industry is also facing the problem of labor shortage. In addition, the manufacturing process of the electronic industry is usually easy to cause pollution to the environment, coupled with the increasing demand for environmental protection in the social environment, the operation mode of traditional processing and manufacturing is also constantly being affected. [0003] Take the display components of electronic products as an example. With the advancement of flat-panel display production technology, the new generation of products are designed in the direction of lighter, thinner and more flexible. The purpose is to provide more...

[0004] In addition, the current attachment process of flexible films in display components, such as Image 6 As shown, a vacuum chamber A0 is set inside the vacuum pump A, a movable roller A1 is arranged in the vacuum chamber A0, and a feeding part A2 is set on the top of the vacuum chamber A0, and there is no feeding part A3 around the feeding part A2 That is, it is sealed with glue or tape, etc., which can prevent the vacuum pump A from leaking, and the feeding part A2 is equipped with a third adsorption platform A21, which can be used to fix the film B to be attached, and then set a suction platform C above the vacuum pump A to absorb For the sheet film C1, when the processing operation is in progress, the vacuum chamber A0 of the vacuum pump A needs to be pumped into a vacuum state, but it must wait for a long time due to vacuuming, and it is necessary to prevent air leakage from the non-feeding part A3 of the vacuum pump A , which increases the difficulty of the film sticking process, which is quite time-consuming and labor-intensive, and the roller A1 is used in the vacuum chamber A0 to rise and push the third adsorption platform A21, so that the film B to be attached on the third adsorption platform A21 can be pasted on the The surface of the sheet film C1, while the general film B to be attached is quite thin and soft, when the roller A1 lifts the third adsorption platform A21 and the film B to be attached to the top, it is also easy to attach the third adsorption platform A21. The network mark of the adsorption platform A21 is transferred to the surface of the film B to be attached or the sheet film C1, and the sheet film C1 becomes a substandard product due to the network pattern

[0005] recombine Figure 7 As shown, it is another vacuum film processing mode commonly used at present. In order to provide a third flexible film A01 at the bottom of the vacuum chamber A0 inside the vacuum pump A, a roller A1 is set on the outside of the third flexible film A01. The top of the vacuum chamber A0 is equipped with a feeding part A2, and the non-feeding part A3 around the feeding part A2 is sealed with glue or tape to prevent air leakage from the vacuum pump A, and the feeding part A2 is provided with a third adsorption platform A21, for fixing the film B to be attached, and then setting the suction platform C above the vacuum pump A to absorb the sheet film C1, so setting the roller A1 outside the vacuum pump A can reduce the volume of the vacuum pump A and shorten the vacuum chamber A0 During the vacuuming operation time, when the processing operation is in progress, the roller A1 pushes up against the third flexible film A01 to push the third adsorption platform A21 to attach the film B to be attached to the surface of the sheet film C1, but the roller A1 A1 continues to push the third flexible film A01, which is likely to cause damage and rupture of the third flexible film A01, so the third flexible film A01 must be replaced frequently, and attention must still be paid to the vacuum chamber A0 of the vacuum pump A to maintain a vacuum state without air leakage. It may happen that the texture of the third adsorption platform A21 is transferred to the surface of the film B to be attached or the surface of the sheet film C1, causing the sheet film C1 to become a substandard product due to the texture

[0006] Furthermore, in the above-mentioned processing method for pasting flexible films currently used, when maintaining the vacuum state of the vacuum chamber A0 inside the vacuum pump A, attention must be paid to the integrity of the sealing of the non-feeding part A3 around the feeding part A2, so as to avoid the occurrence of Air leakage, regardless of whether the roller A1 is set inside or outside the vacuum chamber A0 of the vacuum pump A, will easily cause damage to the third adsorption platform A21 and the third flexible film A01, and the anilox transfer of the third adsorption platform A21 will occur. To the surface of the film B to be attached or the surface of the sheet film C1, etc., and because the size of the sheet film C1 is different, the size of the film B to be attached will also change accordingly, then the size of the feeding part A2 and the non-feeding part A3 It should also be changed. The non-feeding part A3 needs to be sealed again with glue or tape to prevent air leakage in the vacuum chamber A0, which also leads to more cumbersome and inconvenient preparations for processing operations.
