Description

Technical Field

[0001] The invention relates to the technical field of electronic special thin film plating, in particular to an automatic vacuum coating machine. Background Art

[0002] Films are divided into capacitor films, polypropylene films, BOPP films, vacuum coatings, etc. Coatings are divided into vacuum coatings and electroplatings. Vacuum coatings have good adhesion strength and are not easy to fall off, but their own corrosion resistance is not as good as electroplated films. Electroplated films have good corrosion resistance.

[0003] The prior art discloses a Chinese patent with application number CN201810530860.4 (IPC classification number: C23C14 / 32), a coating machine, and discloses that the invention has a simple structure and occupies a small area. The vacuum pump draws out the internal gas to form a vacuum state in the inner cavity, thereby improving the coating work efficiency and effectively improving the coating uniformity.

[0004] However, the prior art still has certain defects. For example, the technical solution with application number CN201810530860.4 can reduce the floor space to realize coating operation. However, coating is often a large-scale continuous operation. Therefore, large-scale coating operation cannot be realized. Moreover, during coating, the diameter of the film roll becomes larger and larger as the film is retracted and released. Therefore, the speed of film reeling is not fast enough to release the film, which may cause the film to loosen during coating and the film cannot be cut into batches of different specifications after reeling.

In addition, the setting of the pressing roller 297 can also rotate when the film is stretched and moved, without hindering its stretching movement.

[0056] When the film is unwound and wound at the same time in cooperation with the unwinding unit 2, the first motor 20 is started to drive the first push rod 22 to rotate. When the first push rod 22 rotates, it drives the fixed box 23 to rotate, thereby driving the fixed film roll to unwind. At this time, under the action of the pulley 393 and the belt 394, the outer disk 33 is driven to rotate, and finally the film after coating is wound. The electric slider is opened to drive the rotating member 35 to rotate clockwise. The rotating member 35 synchronously drives multiple protrusions to rotate. When the protrusions rotate, they squeeze multiple moving plates 38 so that the clamping members 39 clamp the two sides of the winding drum of the wound film for winding and winding. When the rotating member 35 rotates counterclockwise, the multiple clamping members 39 cancel the clamping of the winding drum, and then the second push rods 32 on both sides are opened to make the wound film fall. The spring in the outer sleeve 390 squeezes the inner sleeve 391 so that the side plates 392 on both sides are always in contact with the two side edges of the wound film, effectively avoiding the deviation of the film when winding.

[0057] When the film coater 41 coats the film, the electroplating technology is used. Electroplating is to reduce the metal ions in the electrolyte solution with metal ions to the surface of the object through the action of the electric current in the electrolyte solution, thereby forming a layer of metal film. This is the prior art and therefore will not be described in detail. When the film after coating is rolled up, the diameter of the rolled film roll becomes larger and larger, and the film will loosen after being placed for a period of time. At this time, the adjustment control 48 is rotated to drive the cross bar 44 to lift, and then the fixing pin 490 is placed in the corresponding fixing hole 47 through the placement hole 49 to complete the lifting and tightening of the loosened film.

[0058] When the film coil after coating is cut at equal intervals, the second motor 522 is turned on according to the width of the film to be cut. The second motor 522 is turned on to drive the rotating rod 524 to rotate. At this time, the rotating rod 524 is driven to rotate through the sprocket 525 and the chain 526. When the rotating rod 524 rotates, the driving plate 517 is driven to move up and down through the connecting member 527. When the driving plate 517 moves up and down, it drives the inserted shaft 519 through the regulating groove 518 to adjust the equal intervals between the multiple vertical plates 514, so that the spacing of the cutting members 534 below is adjusted to meet the needs of batch cutting of different specifications of film rolls. When the electric slider is turned on to drive the inner disk 34 to rotate in the outer disk 33, the regulating rod 542 is rotated to make the axis of the semi-arc plate 544 parallel to the axis of the upper film roll. Then the electric slider is turned on to make the lower teeth 549 drive the inner arc 547 to rotate out of the arc groove 546, thereby supporting the lower part of the film roll when it is rotating to prevent it from deforming during cutting.
