Description

Technical Field

[0001] This utility model relates to the field of film application equipment, and in particular to a vacuum film pressing mechanism. Background Technology

[0002] Existing curved screen electronic products have curved sides. To provide adequate protection for the screen of such electronic products, curved screen protectors have emerged. Curved screen protectors include a flat part and curved parts on both sides. When applying the protector, the protector is first pre-applied to the screen using a protector applicator, and then the protector and air bubbles between the protector and the screen are smoothed out using a squeegee. However, because the sides of curved screen phones are curved, it is difficult to operate by using a squeegee, resulting in poor side adhesion and easy lifting of the edges, which affects the use of electronic products. To address this, a vacuum pressing mechanism has been proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-11 In this embodiment of the present invention, a vacuum film pressing mechanism is disposed inside an automatic film applicator 1. It includes a mounting frame 2 disposed inside the automatic film applicator 1, and a mounting platform 3 is disposed on the mounting frame 2. A support frame 5 is vertically disposed on one side above the mounting platform 3, and a film pressing plate 18 is horizontally disposed inside the support frame 5. A silicone film 28 that moves synchronously with the film pressing plate 18 is disposed at the bottom end of the film pressing plate 18. A jig 6 for transporting electronic products is disposed between the mounting platform 3 and the support frame 5. The jig 6 is slidably located on the mounting platform 3. The electronic products held above the jig 6 can be filmed and moved to the bottom of the support frame 5 through the jig 6, so that the jig 6 and the film pressing plate 18 are parallel to each other. An air nozzle 22 connected to its pipeline is disposed outside the jig 6.

[0032] Then, when the fixture 6, along with the applied film, is transported to the support frame 5, the pressure plate 18, along with the silicone film 28, moves downwards and covers the fixture 6. At this time, the silicone film 28 is applied to the electronic product. Then, through the cooperation of the air nozzle 22 and the external air extraction device, the internal air in the space formed between the pressure plate 18 and the fixture 6 is discharged, creating a negative pressure inside the space. Under the action of the negative pressure, the silicone film 28 is tightly pressed onto the electronic product, further pressing the film material on the electronic product. This makes it less likely for the edges of the film material to lift off when it is applied to the electronic product. When the electronic product is a curved screen mobile phone and the silicone film 28 is tightly pressed onto the curved screen mobile phone, the silicone film will press the film material onto the curved surface of the curved screen mobile phone, so that the film material fits the curved surface of the curved screen mobile phone, in order to meet the needs of applying films to electronic products with different screen surfaces.

[0033] A groove 29 is provided between the pressure plate 18 and the silicone film 28, and the groove 29 is formed at the bottom end of the pressure plate 18. The groove 29 arches upward, and the silicone film 28 is horizontally placed at the opening of the groove 29. Thus, when the pressure plate 18 covers the fixture 6, the electronic product on the fixture 6 will push the silicone film 28 into the groove 29, and the groove 29 allows the pressure plate 18 to cover the fixture 6, pressing and limiting the electronic product placed on the fixture 6, so that the silicone film 28 can stick tightly to the electronic product under the action of negative pressure.

[0034] A slot 30 is provided between the pressure plate 18 and the silicone film 28. The slot 30 is formed below the pressure plate 18 and surrounds the side of the groove 29. The silicone film 28 is provided with a protrusion 31 that engages with the slot 30. The protrusion 31 is surrounded above the silicone film 28. The engagement between the protrusion 31 and the slot 30 allows the silicone film 28 to be installed below the pressure plate 18.

[0035] A film material placement rack 4 is provided on one side of the support frame 5 to support the film material crossbeam. The film material placement rack 4 is vertically arranged on the mounting platform 3. A first driving member 8 is provided between the film material placement rack 4 and the mounting platform 3. The first driving member 8 is vertically located below the mounting platform 3 and is driven to the bottom of the film material placement rack 4. The first driving member 8 drives the film material placement rack 4, along with the film material placed on its top, to move up and down on the mounting platform 3. When the fixture 6 moves the electronic product held above it to the position below the film material placement rack 4, the film material placement rack 4 moves downward so that the film material placed on its upper crossbeam is attached to the screen of the electronic product.

[0036] A first mounting plate 12 is vertically mounted on one side of the pressing plate 18, and a first roller mounting frame 13 is vertically mounted on one side of the first mounting plate 12. A first roller 14 for rolling the film material is rolled at the bottom end of the first roller mounting frame 13. A third driving member (not shown in the figure) is provided between the first mounting plate 12 and the first roller mounting frame 13. The third driving member is laterally located on one side of the first mounting plate 12, and the third driving member is driven to the first roller mounting frame 13.

[0037] Then, the third driving component drives the first roller mounting frame 13, along with the first roller 14, to move back and forth above the film material placement frame 4. During the movement, the first roller 14 rolls back and forth above the film material placement frame 4. When the electronic product with the screen facing upward is placed inside the fixture 6, the fixture 6, along with the electronic product, moves to a position below the film material placement frame 4, which holds the film material. At this time, the film material placement frame 4, along with the film material, moves downward and the adhesive side of the film material adheres to the screen of the electronic product. The third driving component drives the first roller mounting frame 13 to move horizontally above the film material placement frame 4. During the movement, the first roller mounting frame 13 causes the first roller 14 to roll above the film material, rolling the film material onto the screen of the electronic product and allowing the film material to adhere forward to the screen of the electronic product, thus completing the film application process for the electronic product.

[0038] On the other side of the pressure plate 18, a second mounting plate 15 is vertically arranged opposite to the first mounting plate 12. On one side of the second mounting plate 15, a second roller mounting frame 16 is vertically arranged opposite to the first roller mounting frame 13. A second roller 17 is rolled at the bottom of the second roller mounting frame 16 to perform a second rolling on the film material. Thus, when the fixture 6 moves the film-coated electronic product out from under the pressure plate 18, the second roller 17 performs a second rolling on the film material attached to the electronic product, making the adhesion between the film material and the electronic product more firm.

[0039] The fixture 6 includes a fixed base 25 that spans its interior. At both ends of the surface of the fixed base 25, there are second clamping blocks 21 arranged laterally to clamp the front and rear ends of the electronic product. At both sides of the surface of the fixed base 25, there are first clamping blocks 20 that clamp the sides of the electronic product. The first clamping blocks 20 are mounted on the second clamping blocks 21. The first clamping blocks 20 can move left and right on the surface of the second clamping blocks 21, and the second clamping blocks 21 can move back and forth on the surface of the fixed base 25, thereby clamping the electronic product placed inside the fixture 6.

[0040] The first clamping block 20 is provided with a first transmission rack 23 that moves synchronously therewith, and the second clamping block 21 is provided with a second transmission rack 24 that moves synchronously therewith. A first gear motor 26 that meshes with the first transmission rack 23 is provided on one side of the bottom end of the fixed base 25, and a second gear motor 27 that meshes with the second transmission rack 24 is provided on the other side of the bottom end of the fixed base 25. Through the driving cooperation between the first gear motor 26 and the first transmission rack 23 and the second gear motor 27 and the second transmission rack 24, the first clamping block 20 and the second clamping block 21 can be opened and closed inside the fixture 6 respectively, thereby clamping electronic products placed inside the fixture 6.

[0041] The fixture 6 is also provided with a product support plate 19 for supporting electronic products. The product support plate 19 is horizontally mounted above the fixed base 25. The first clamping block 20 and the second clamping block 21 are respectively located on the side of the product support plate 19 and can move on the side of the product support plate 19 to clamp the electronic products placed on the product support plate 19 to accommodate electronic products of different sizes.

[0042] A second driving member 11 is provided between the support frame 5 and the pressure plate 18, and the second driving member 11 is located at the top of the support frame 5. The second driving member 11 is connected to the pressure plate 18, thereby driving the pressure plate 18 and the silicone film 28 to rise and fall inside the support frame 5, so as to drive the pressure plate 18 and the silicone film 28 to cover the fixture 6.

[0043] A motor 9 is provided between the mounting platform 3 and the fixture 6, and the motor 9 is located on one side of the mounting platform 3. The fixture 6 is provided with a slider 7 that moves synchronously with it and slides on the mounting platform 3. The motor 9 is provided with a transmission belt 10 that drives the slider 7. The transmission belt 10 is arranged around the mounting platform 3. The motor 9 drives the transmission belt 10 to rotate around the mounting platform 3, thereby moving the slider 7 on the mounting platform 3 and moving the fixture 6 on the mounting platform 3, and transferring the electronic product held by the fixture 6.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
