[0002] Silicone protective film is a PET protective film with an additional layer of organic silicone coating on the original PET film. It is formed at high temperature and has the characteristics of high transparency, high exhaust, good adhesion, and no glue marks. The dielectric constant of the base material of the silicone protective film is small, which makes the film easy to carry charge. After being attached to electronic equipment, it is easy to absorb charged dust in the air, especially in some workshops with low dustproof requirements.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] See also Figures 1 to 9 The present invention provides a method for preparing an antistatic silicone protective film, comprising the following steps:

[0041] S1: Mix the following components by mass percentage: 90-95% silica gel, 1-1.5% ethyl acetate, 0.5-1% toluene, 0.5-1% xylene, and 3-5% antistatic additive by stirring through a stirring device to obtain a coating slurry;

[0042] S2: coating the coating slurry on two groups of base layers respectively by a coating device to obtain a film blank A and a film blank B;

[0043] S3: The film blanks A and B are dried by a drying device;

[0044] S4: passing the film blanks A and B into the cooling liquid for cooling;

[0045] S5: Film blank A and film blank B are respectively attached to two sides of the new base film by means of single-sided adhesive to form an antistatic silicone protective film finished product;

[0046] S6: Finished product of anti-static silicone protective film is rolled up;

[0047] S7: The finished anti-static silicone protective film is cut into pieces, and then packaged after being cut and shaped by the preparation device. The cut product film is placed on the laying table 2, and the laminating mechanism 3 automatically adsorbs and tightens the finished film. The cutting mechanism 4 is used to divide it, and the small pieces of finished film after division fall to the collecting mechanism 1, and then enter the conveyor belt 6 through the guide slope 12, and are collected centrally by the conveyor belt 6.

[0048] In step S2, the two sets of base layers are made of the same material, and the base layers may be PET, a release film or a release paper.

[0049] In step S5, the new base film may be a PET film, a PI film or a release film.

[0050] The present invention is being delivered, please refer to Figure 8 , by coating two groups of base layers separately to obtain film blanks A and film blanks B, and then laminating film blanks A and film blanks B on the two surfaces of the new base film respectively. In this way, film blanks A and film blanks B are independently coated and formed and then laminat... ed on the new base film. Compared with double-sided coating, the film quality is improved while ensuring the production efficiency of the protective film.

[0051] After cutting into pieces in step S7, it is necessary to use forming equipment for cutting and forming. In order to ensure the stability of the film during cutting, the forming equipment generally has an electrostatic adsorption function. Compared with general film products, direct adsorption is sufficient. However, the anti-static silicone protective film product has insufficient adsorption capacity compared with traditional protective films, and is prone to movement during cutting and forming. Therefore, we propose an anti-static silicone protective film preparation device for the forming and cutting of anti-static silicone protective films.

[0052] The antistatic additive is a mixture of long-chain alkyl quaternary ammonium salt and alkyl sulfonate, with the ratio of the two being 1:1.

[0053] An antistatic silicone protective film preparation device includes a material laying table 2 and a cutting mechanism 4, wherein the cutting mechanism 4 is used to cut the finished film placed on the material laying table 2, and further includes:

[0054] The collecting mechanism 1 includes a base 11, a collecting trough 111, a material guiding slope 12, and a conveyor belt 6. The base 11 is arranged below the material laying platform 2. The cut finished film falls into the collecting trough 111 and is guided by the material guiding slope 12 to be transported to the conveyor belt 6.

[0055] Laminating mechanism 3;

[0056] Flow guiding mechanism 7;

[0057] A control mechanism 8 having a first state and a second state, wherein the control mechanism 8 is switched between the first state and the second state by changing the position of the cutting mechanism 4;

[0058] Among them, in the first state, the control mechanism 8 controls the laminating mechanism 3 to adsorb the finished film and tighten it to both sides, so that the finished film is fixed on the laying table 2. In the second state, the guide mechanism 7 is opened, so that the guide mechanism 7 transports the lubricating liquid to the guide slope 12.

[0059] In the embodiment of the present invention, when placing the finished film, the cutting mechanism 4 is away from the discharge area of ​​the material laying table 2, and the finished film is manually laid on the material laying table 2. At this time, the cutting mechanism 4 is outside the discharge area, and the control mechanism 8 is in the first state. The laminating mechanism 3 will be adsorbed on the lower surface of the finished film. After adsorption, the laminating mechanism 3 automatically moves to both sides to tighten the finished film. In this way, it is ensured that the finished film is always in a stable state during the cutting process, thereby improving the cutting and forming quality.

[0060] When cutting, the cutting mechanism 4 cuts the finished film, and the cut film pieces fall onto the material guide slope 12. After passing through the material guide slope 12, the film pieces are transported to the conveyor belt 6, and the conveyor belt 6 collects the film pieces through the conveyor belt 6;

[0061] During cutting, the cutting mechanism 4 is disengaged from the control mechanism 8, and the control mechanism 8 is switched to the second state. At this time, the flow guide mechanism 7 is turned on, and the flow guide mechanism 7 can continuously transport lubricating liquid to the material guide slope 12. Under the flushing of the lubricating liquid, the diaphragm moves downward more smoothly, reducing the probability of the diaphragm sticking to the material guide slope 12, and the diaphragms are automatically collected and concentrated, with a high degree of automation.

[0062] In the embodiments of the present invention, please refer to Figures 2 to 4The control mechanism 8 includes a fixed frame 81, a first pipe 82, a second pipe 83, an elastic member 84, a toggle plate 85, a vacuum pump 10, and a third pipe 101. The fixed frame 81 is fixedly installed on the base 11. One end of the first pipe 82 and the second pipe 83 are both installed on the fixed frame 81. The other end of the first pipe 82 is connected to the guide mechanism 7, and one end of the second pipe 83 is connected to the bonding mechanism 3. The toggle plate 85 is slidably connected above the laying table 2. The elastic member 84 applies a thrust to the toggle plate 85 in the direction of the cutting mechanism 4. One end of the third pipe 101 is connected to the vacuum pump 10, and the other end of the third pipe 101 is fixed on the toggle plate 85.

[0063] Under the elastic force of the elastic member 84, a thrust toward the cutting mechanism 4 will always be applied to the toggle plate 85. In the feeding stage of the finished film, the cutting mechanism 4 needs to leave the placement area of ​​the material laying table 2, so the cutting mechanism 4 will move to the area where the toggle plate 85 is located, and the cutting mechanism 4 will squeeze the toggle plate 85. The toggle plate 85 will resist the elastic force of the elastic member 84 and move. When the toggle plate 85 moves, it will drive the end of the third pipe 101 to move. Under the squeezing of the cutting mechanism 4, the third pipe 101 will be connected to the second pipe 83. At this time, the vacuum pump 10 will suck the air in the third pipe 101 and the second pipe 83. Gas, similarly, the air in the laminating mechanism 3 is also sucked so that the laminating mechanism 3 can adsorb the lower surface of the finished film, and during cutting, the cutting mechanism 4 and the toggle plate 85 are separated, and the toggle plate 85 will be reset under the elastic force of the elastic member 84, and the displacement of the toggle plate 85 will synchronously drive the third pipe 101 to move, and the third pipe 101 will be disconnected from the second pipe 83, and the third pipe 101 will be connected to the first pipe 82, so that the vacuum pump 10 will suck the air in the first pipe 82, and by changing the position of the cutting mechanism 4, the connecting pipe of the vacuum pump 10 can be passively changed to achieve different purposes.

[0064] In the embodiments of the present invention, please refer to Figure 5 The fitting mechanism 3 includes a movable box 31, a strip-shaped adsorption hole 311, and a side box 32. The side box 32 is fixedly mounted on the material laying platform 2. The movable box 31 is slidably sleeved on the side box 32. The strip-shaped adsorption hole 311 is opened at the upper part of the movable box 31. The second pipe 83 is connected to the side box 32.

[0065] In the first state, the vacuum pump 10 is connected to the second pipe 83, so that the air in the side box 32 is sucked, the finished film is covered in the movable box 31, and the side box 32 is blocked by the finished film. At this time, the air inside the movable box 31 is also sucked to form a negative pressure state, so that the finished film will be adsorbed in the movable box 31, and because of the negative pressure, the movable box 31 has a tendency to move toward the side box 32. In this way, after the movable box 31 adsorbs the finished film, it will automatically tighten the finished film on both sides, so that the finished film is fixed, thus ensuring the stability during cutting. A second one-way valve is provided on the second pipe 83. After the vacuum pump 10 and the second pipe 83 are disconnected, the second pipe 83 is ensured to be in a negative pressure state to ensure that the finished film is still fixed during the cutting operation. After the cutting is completed, the remaining finished film is manually pulled outward. When the pulling force is greater than the adsorption force, the remaining finished film will be detached from the laying table 2; further, when pulling, under the action of the adsorption force, the movable box 31 will first be driven to move away from the side box 32 until the movable box 31 moves to the extreme position. At this time, under the action of continuous pulling force, the pulling force is greater than the adsorption force, and the finished film and the movable box 31 are detached. In this way, there is no need to manually reset the movable box 31, making it more convenient.

[0066] In another embodiment of the present invention, please refer to Figure 5 and Fig. 9 The bottom of the movable box 31 is slidably connected to the pin key 33, and a pin hole matching the pin key 33 is provided on the material spreading platform 2.

[0067] The setting of the pin key 33 has a certain locking effect. After the movable box 31 is completely blocked, as the vacuum pump 10 continues to suck, the negative pressure in the movable box 31 will drive the pin key 33 to move up. After moving up, the pin key 33 will be separated from the laying table 2, so that the movable box 31 can be moved smoothly.

[0068] In an embodiment of the present invention, the flow guide mechanism 7 includes a storage box 71, a first plug plate 711, an air pressure box 72, a second plug plate 722, a fourth pipe 74, and a connecting frame 73. The first plug plate 711 is slidably connected in the storage box 71, the second plug plate 722 is slidably connected in the air pressure box 72, the first plug plate 711 and the second plug plate 722 are fixedly connected by the connecting frame 73, the storage box 71 is connected to the collecting tank 111 through the fourth pipe 74, and the first pipe 82 is connected to the air pressure box 72.

[0069] The water receiving tray 5 is also included. A fifth pipe 51 is disposed at the lower portion of the water receiving tray 5. The other end of the fifth pipe 51 is connected to the storage box 71 via a first one-way valve.

[0070] When cutting the finished film, the cutting mechanism 4 disengages from the toggle plate 85, and under the elastic force of the elastic member 84, the toggle plate 85 is displaced to achieve the connection between the first pipe 82 and the third pipe 101, so that the vacuum pump 10 will suck the air in the air pressure box 72, and the pressure in the air pressure box 72 will decrease, and the second plug plate 722 will move downward, and the second plug plate 722 will synchronously drive the first plug plate 711 to descend under the connection action of the connecting frame 73. When the first plug plate 711 descends, it will squeeze the lubricating liquid stored in the storage box 71, and the lubricating liquid will be transported to the collecting tank 111 through the fourth pipe 74, and the lubricating liquid will flow along the material guide slope 12. After the cutting is completed, the film will fall into the collecting tank 111, and driven by the lubricating liquid, the film will move smoothly to the conveyor belt 6 for conveying. The belt 6 is a mesh structure with water permeability. The lubricating liquid passes through the conveyor belt 6 and falls into the water receiving tray 5, and the water receiving tray 5 collects the lubricating liquid. After the cutting is completed, the first pipe 82 and the third pipe 101 are disconnected. At this time, the air pressure box 72 loses the negative pressure, and the water receiving tray 5 is higher than the storage box 71. The lubricating liquid will flow back to the storage box 71 under the connection of the fifth pipe 51. The first plug plate 711 and the second plug plate 722 are both made of lightweight materials. A spring is arranged in the air pressure box 72 to assist the upward reset of the first plug plate 711 and the second plug plate 722. The setting of the first one-way valve can ensure that the lubricating liquid can only flow from the water receiving tray 5 through the fifth pipe 51 into the storage box 71. After cutting, the diaphragm is automatically collected, and the flow of the lubricating liquid on the guide slope 12 is used to increase the smoothness of the movement of the diaphragm.

[0071] A guide groove 121 is provided on the guide slope 12, and the lubricating liquid will flow through the guide groove 121. The width of the guide groove 121 narrows from the upper part to the lower part of the guide slope 12. In this way, during the flow of the lubricating liquid, it will overflow from the guide groove 121, which can effectively prevent the diaphragm from being adsorbed on the guide slope 12.

[0072] The lubricating fluid can also clean the diaphragm during the flow process, and the powder generated during cutting will be washed away by the lubricating fluid.

[0073] In an embodiment of the present invention, the cutting mechanism 4 includes a first track frame 41 and a second track frame 42 . The first track frame 41 is arranged on both sides of the material laying platform 2 , the second track frame 42 is arranged on the first track frame 41 , and the toggle plate 85 is arranged on the moving path of the second track frame 42 .

[0074] By setting the toggle plate 85 on the moving path of the second track frame 42, the second track frame 42 can change the position of the toggle plate 85. In this way, according to different cutting processes, the connection of the vacuum pump 10 is passively adjusted to automatically switch the control mechanism 8 between the first state and the second state. The cutting mechanism 4 is controlled by the corresponding servo system, and its principle will not be repeated here.

[0075] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
