[0091] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0092] like Figure 1-18 As shown, this embodiment proposes an MPI production device with anti-missing coating function, including a base plate 1, a housing 6, transfer rollers 11, a first support 4, and a fixing plate 7. The first support 4 is welded to the base plate 1, and the fixing plate 7 is welded to the support set on the base plate 1. There are two fixing plates 7, and a notch is provided between the two fixing plates 7. The housing 6 is welded to the fixing plate 7, and a plurality of transfer rollers 11 are provided, which are rotatably disposed inside the housing 6.

[0093] It also includes a tool changing mechanism.

[0094] The tool changing mechanism includes,

[0095] Two third supports 10 are provided, and the two third supports 10 are welded to the fixing plate 7.

[0096] A tool mounting assembly is installed at the upper end between the two third supports 10.

[0097] A reciprocating lateral movement assembly is installed between the two third supports 10.

[0098] In this embodiment, after the PI film is coated and dried by the conveying roller 11, the doctor blade 30 may experience uneven coating due to wear and adhesive residue. The doctor blade mounting assembly on the third support 10 will move the new doctor blade 30 to the designated position by moving it horizontally upward. The reciprocating horizontal moving assembly on the third support 10 will move the mounting frame 9 horizontally and then reset it, so that the doctor blade 30 is installed in the mounting frame. This allows the doctor blade to be replaced without stopping the machine, reducing the phenomenon of missed coating. Example

[0099] Based on the first specific implementation method, such as Figure 4-8 As shown, the tool mounting assembly includes,

[0100] Two second telescopic rods 20 are provided, and the two second telescopic rods 20 are welded to the third bracket 10.

[0101] Push rod 21, which is welded to the second telescopic rod 20.

[0102] The fourth bracket 27, of which two are provided, are welded to the third bracket 10.

[0103] T-shaped guide rail 26, which is welded to the third bracket 10.

[0104] A first mounting bracket 22 is provided with a sliding rod, which is slidably disposed in the T-shaped guide rail 26. One end of the first mounting bracket 22 is provided with a groove, which contacts the push rod 21.

[0105] Based on the first specific implementation method, such as Figure 9-11 As shown, the tool mounting assembly also includes,

[0106] Two C-shaped clips 23 are provided, and the two C-shaped clips 23 are bolted to the first mounting bracket 22.

[0107] Electric turntable 24, which is mounted on the C-shaped clamp 23.

[0108] An extrusion plate 25 is welded between the push rods 21 on both sides.

[0109] A lifting rod 28 is provided with a sliding rod at its apex. The lifting rod 28 is slidably mounted in the T-shaped guide rail 26. A crossbar is provided at the lower end of the lifting rod 28.

[0110] The fifth bracket 54 is welded to the moving end of the slide rod provided on the first mounting bracket 22, and the fifth bracket 54 is provided with a slide rail.

[0111] like Figure 12-13 As shown, the tool mounting assembly also includes,

[0112] The second bracket 8 is provided in groups of four, with two second brackets 8 forming a group. The first group of second brackets 8 is welded to the left side of the fixing plate 7, and the second group of second brackets 8 is welded to the right side of the fixing plate 7.

[0113] Support plate 16, which is welded between the second group of second brackets 8.

[0114] Two elastic telescopic rods 29 are provided and bolted to the support plate 16. The telescopic ends of the two elastic telescopic rods 29 are provided with sliders, and the sliders on the two elastic telescopic rods 29 are slidably disposed in the slide rails provided on the fifth bracket 54.

[0115] In this embodiment, the second telescopic rod 20 pushes the push rod 21 to move the extrusion plate 25 to the left, and at the same time pushes the first mounting bracket 22 and the C-shaped clamp 23 on the first mounting bracket 22 to the left. The rotation of the electric turntable 24 causes the C-shaped clamp to clamp the scraper 30, and the new scraper 30 moves to the left through the T-shaped guide rail 26. When the extrusion plate 25 contacts the lifting rod 28, the lifting rod 28 will rise due to the extrusion of the inclined surface of the extrusion plate 25 and be limited by the T-shaped guide rail 26. At this time, the first mounting bracket 22 is pushed by the second telescopic rod 20 to reach above the lifting rod 28, thereby the lifting rod 28 drives the first mounting frame 22 to rise, so that the C-shaped clamp 23 drives the new scraper 30 to move upward to the designated position. After the blade replacement is completed, the first mounting frame 22 will descend downward through the T-shaped guide rail 26 due to gravity. At this time, the elastic telescopic rod 29 will reset the first mounting frame 22 and the C-shaped clamp 23. The slide rail on the fifth bracket 54 plays a limiting role, realizing the lateral and longitudinal translation of the new scraper.

[0116] like Figure 9-10 As shown, it also includes an electric screwdriver assembly, which includes,

[0117] Two third telescopic rods 31 are provided, and the two third telescopic rods 31 are bolted together between the third bracket 10.

[0118] An electric screwdriver 32 is bolted to the telescopic end of the third telescopic rod 31.

[0119] In this embodiment, the tip of the electric screwdriver 32 has a magnetic force that can attract the screw. Before changing the screwdriver, the electric screwdriver 32 rotates by lowering the third telescopic rod 31 to unscrew the screw. Then, the screw is unscrewed by raising the third telescopic rod 31. After changing the screwdriver, the third telescopic rod 31 will lower, and the electric screwdriver 32 will start to rotate to reinstall the screw in the designated position.

[0120] like Figure 11-16 As shown, the reciprocating lateral movement component includes,

[0121] The first rack 55 is welded to the fifth bracket 54.

[0122] Mounting base 37, which is welded to the third bracket 10.

[0123] The second rotating shaft 41 is rotatably mounted on the mounting base 37.

[0124] The spur gear 38 is rotatably mounted on the mounting base 37.

[0125] An arc-shaped guide rail 40 is welded to the second rotating shaft 41.

[0126] A first rotating shaft 39 is rotatably disposed on the spur gear 38 at a location away from the center, and the first rotating shaft 39 is slidably disposed within the arc-shaped guide rail 40.

[0127] The second rack 43 is slidably disposed in a slide rail provided on the third bracket 10.

[0128] A sector gear 42, which is welded to the second rotating shaft 41.

[0129] Connecting plate 44, which is welded between the second toothed racks 43 on both sides.

[0130] Mounting frame 9, which is welded to connecting plate 44, is provided with screw holes.

[0131] The scraper 30 is slidably disposed in the mounting frame 9, and the scraper 30 is provided with screw holes.

[0132] In this embodiment, when the second telescopic rod 20 pushes the first mounting frame 22, the fifth bracket 54 on the slide rod on the first mounting frame 22 will drive the first rack 55 to move to the left. At this time, the spur gear 38 meshing on the first rack 55 will rotate to the right. The maximum rotation angle of the spur gear 38 is 90 degrees counterclockwise and 90 degrees clockwise, and each 90-degree rotation completes one movement. At the same time, the first rotating shaft 39 on the spur gear 38 will rotate with the spur gear 38. At this time, the first rotating shaft 39 will slide back and forth in the arc-shaped guide rail 40, thereby driving the arc-shaped guide rail 40 to swing left and right, thereby driving the second rotating shaft 41 to rotate left and right, so that the sector gear 42 swings left and right at the same time. The sector gear 42 will drive the second rack 43 meshing with it to move left and right in the slide rail on the third bracket 10. Through the connecting plate 44, the mounting frame 9 will move laterally together. First, the mounting frame 9 will move to the right. When the new scraper just moves to the designated position, the mounting frame 9 will move to the left to reset, thereby realizing the replacement of the tool. Example

[0133] Based on the second specific implementation method, such as Figure 7-9 As shown, it also includes a supply component, which includes,

[0134] The first telescopic rod 18 is bolted to the third bracket 10.

[0135] Push plate 19, which is bolted between the telescopic ends of the first telescopic rods 18 on both sides.

[0136] The tool supply box 17 is welded to the third brackets 10 on both sides.

[0137] In this embodiment, when the scraper 30 needs to be replaced, the scraper box 17 contains several new scrapers 30. Each time the scraper is replaced, the scraper box 17 will automatically drop a new scraper 30. The distance between the scraper box 17 and the straight plate is exactly the same as the height of the scraper 30. First, the first telescopic rod 18 at the rear will push the push plate 19 to push the new scraper 30 to the designated position. Then, the first telescopic rod 18 will drive the push plate 19 to retract, and the new scraper 30 will continue to fall onto the straight plate below until the next time a new scraper 30 is detected to be replaced, it will move again.

[0138] like Figure 14-17 As shown, it also includes a recycling component, which includes,

[0139] The slide rail 35 is welded between the two third supports 10.

[0140] Two guide rods 36 are provided, and the two guide rods 36 are slidably disposed in the slide rail 35. A mounting plate is provided between the bottom ends of the two guide rods 36, and two slide rails are respectively provided on both sides of the mounting plate.

[0143] Collection box 45, which is welded to the fixing plate 7.

[0144] A cleaning scraper 46 is welded to the collection box 45. The inner dimensions and shape of the cleaning scraper 46 are the same as those of the blade of the scraper 30.

[0145] In this embodiment, when the scraper 30 needs to be replaced, after the screw is unscrewed by the electric screwdriver 32 and the mounting frame 9 moves to the right, the C-shaped clamp 23 on the fifth telescopic rod 33 will clamp the old scraper 30 by the rotation of the electric turntable 24. At this time, the fifth telescopic rod 33 will immediately rise to raise the old scraper 30 to its limit position. After the new scraper 30 is replaced, the guide rod 36 will move upward to the collection box 45 via the slide rail 35. When the old scraper 30 reaches the top of the collection box 45, the cleaning scraper 46 will scrape off the adhesive on the old scraper 30. The cleaning scraper 46 uses a material that absorbs adhesive, which can easily absorb the adhesive. When the old scraper 30 reaches the top of the collection box 45, the electric turntable 24 will rotate in the opposite direction, causing the C-shaped clamp 23 to release the old scraper 30. At the same time, the sixth telescopic rod 34 will push to both sides, causing the old scraper 30 to fall into the collection box 45, thereby realizing collection and reuse. Example

[0146] Based on the third specific implementation method, such as Figure 4-5 and Figure 18 As shown, it also includes a roller assembly, the roller assembly comprising,

[0147] Three stretching rollers 12 are provided, and the three stretching rollers 12 are rotatably disposed inside the right side of the housing 6.

[0148] The glue-applying roller 13 is rotatably mounted between the two second supports 8 on both sides.

[0160] The collecting roller 3 is bolted to the telescopic end of the seventh telescopic rod 2.

[0161] In this embodiment, the PI film is conveyed to the stretching roller 12 via the transfer roller 11. The support of the three stretching rollers 12 has elastic members with opposite vertical directions. The elastic members of the first and third stretching rollers 12 point downwards, while the elastic member of the second stretching roller 12 points upwards, thus stretching the PI film and preventing wrinkles, thereby further enhancing the uniformity of coating. After coating, the PI film is coated by the slit coating assembly 14, and then the adhesive is evenly scraped by the scraper 30. Excess adhesive drips onto the lower coating roller 13, and the brush roller 15 cleans up the dripped adhesive by rotating. The PI film is then conveyed by the conveyor belt 47. The film is fed into the dryer 48 for drying. The PI film is bonded by the pressing of the bonding roller 51. After bonding, the propylene glycol methyl ether acetate solution in the water tank 49 is sprayed onto the edge adhesive overflow of the PI film through the nozzle 50 to dissolve the edge adhesive. The dissolved edge adhesive and solution are adsorbed and cleaned by the adsorption roller in front. When the PI film falls to the collecting roller 3, the rotating pressure rod 53 will rotate counterclockwise to press the PI film down until it contacts the collecting roller 3. The collecting roller 3 will rotate to roll up and collect the PI film. After collection, the collecting roller 3 will retract backward through the seventh telescopic rod 2, so that the rolled PI film will fall and be collected.

[0162] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
