Description

Technical Field

[0001] The invention belongs to the field of flexible circuit board processing equipment, and in particular relates to a fully automatic roll-to-roll double-sided copper pasting machine. Background Art

[0002] Flexible Printed Circuit (FPC) has the characteristics of high wiring density, light weight, thin thickness, good bendability, etc. It is widely used in electronic components. During its production process, the flexible circuit board needs to be coated to protect the flexible circuit board from damage.

[0003] During the production of flexible circuit boards, multiple layers of tapes need to be bonded together to form different conductive layers. Existing equipment for laminating flexible circuit boards uses multiple conveyor rollers to guide the tapes, and each time the tape passes through the transmission roller, it will bend due to the change in the conveying direction. After the bending, wrinkles and other defects will appear on the surface of the tape, affecting the laminating effect of the covering film. When laminating the covering film, it is necessary to ensure good cleanliness, so the liner paper on the surface is generally torn off before the covering film is laminated. The existing liner paper is peeled off by rotating the reel, but due to different processing techniques, the liner paper on some specifications of tapes is broken, not a complete strip, which makes it difficult to tear the liner paper. At the same time, hot pressing is required after the covering film is laminated to make the lamination between the tapes more firm, but the existing hot pressing is carried out by a pressing roller, and the pressing roller will be stained with dust during the rotation process, and the dust will stick to the surface of the material during the rotation. At the same time, the contact area between the pressing roller and the tape is small, which makes it difficult to control the hot pressing temperature of the tape, which will affect the product quality.

[0004] Therefore, we need to design a fully automatic roll-to-roll double-sided copper bonding machine to solve these problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0045] The present invention will be further described below in conjunction with the accompanying drawings:

[0048] like Figure 2 and Figure 3 As shown, the middle-layer feeding device 11, the upper-layer feeding device 12 and the lower-layer feeding device 13 are all provided with a discharge shaft 101 for installing the material roll, and the material support platform 102 can lift the material tape released from the material roll to prevent the material tape from being stuck due to the sagging of the material tape, thereby affecting the feeding of the front feeding device 21 and the rear feeding device 22. The cleaning roller 103 can clean the dust attached to the surface of the material tape when the front feeding device 21 and the rear feeding device 22 drag the material tape to move, so as to ensure the bonding quality between the material tapes.

[0049] The discharge end of the upper feeding device 12 is connected to the feed end of the upper bonding mechanism 41, and the discharge end of the lower feeding device 13 is connected to the feed end of the lower bonding mechanism 42. The upper feeding device 12 and the lower feeding device 13 also include a pulling device 104, through which the upper material belt or the lower material belt installed on the unwinding shaft 101 can be pulled to move onto the transfer table 106, and the pulling is determined by the sensor set on the upper feeding device 12 or the lower feeding device 13. The length of the material. When the length reaches the specified requirement, the cutting knife 105 will cut the upper material strip or the lower material strip, and the pulling device 104 will be loosened, so that the cut upper material strip or the lower material strip is adsorbed by the transfer table 106, which is convenient for the bonding device to grab. In this embodiment, the cutting knife 105 is a circular rolling knife, and the moving direction is perpendicular to the moving direction of the upper material strip or the lower material strip. The pulling device 104 is located above the transfer table 106 and reciprocates along the moving direction of the upper material strip or the lower material strip.

[0050] like Figure 1 and Figure 4 As shown, the front feeding device 21 and the rear feeding device 22 both include a linear motor 211, a material dragging rack 212 and a clamping plate 213. The linear motor 211 is fixedly arranged on the frame 7, and the material dragging rack 212 is connected to the output end of the linear motor 211.

Because the gravity roller 232 naturally falls down and contacts the material belt through gravity, if the moving speed of the front feeding device 21 is greater than that of the rear feeding device 22 during feeding, the material belt will sag. At this time, the gravity roller 232 will move down with the material belt under the action of gravity, and the magnetic grating reader 234 is driven to output through the guide rod 233, and the output speed of the linear motor 211 on the front feeding device 21 and the rear feeding device 22 is adjusted to ensure the tension of the material belt.

Every time the sliding frame 412 drives the bonding device to move between the transfer table 106 and the middle-layer material belt, the CCD camera of the positioning device 419 will take a picture of the cut upper material belt or the lower material belt on the transfer table 106 to obtain the position status information of the upper material belt or the lower material belt, and then when it moves to the middle-layer material belt, it will take a picture of the position of the middle-layer material belt, and before bonding to the middle-layer material belt, the bonding position of the upper film or the lower film will be adjusted by rotating the rotating motor 421 and moving the position of the bonding device.

[0055] After adjustment, the telescopic motor 420 will output, pushing the connecting frame 417 and the suction cup 414 to push the plate downward.

[0066] Then, the protective film on the upper surface of the middle material strip is peeled off and wound on the upper film winding roll 312, and the protective film on the lower surface of the middle material strip is peeled off and wound on the lower film winding roll 313, and then the position of the stripping knife 314 is adjusted to ensure that the stripping knife 314 can strip off the protective film when the middle material strip moves.

[0067] Then the upper material roll is installed on the unloading shaft 101 on the upper feeding mechanism, and the lower material roll is installed on the unloading shaft 101 on the lower feeding mechanism. Then the ends of the upper material belt and the lower material belt are passed through the supporting platform 102 and the cleaning roller 103 in turn, and then pulled from the side of the cutter 105 and connected to the pulling device 104.

[0068] When the upper material strip and the lower material strip need to be cut, the upper material strip or the lower material strip is pulled and moved by the pulling device 104. After the length meets the requirement, it is fixed by the cutting plate and cut by the cutting knife 105. The cut upper material strip or the lower material strip will be adsorbed by the transfer table 106.

[0069] Then the slide 412 will move along the truss 411. When the suction cup 414 is aligned with the transfer table 106, the transfer table 106 will stop adsorption. At this time, the suction cup 414 will generate suction to suck up the upper material belt or the lower material belt on the transfer table 106. Then the slide 412 will move along the truss 411 again until it is finally aligned with the middle material belt. During this process, the CCD camera of the positioning device 419 will take pictures when the suction cup 414 takes the material from the transfer table 106 to obtain the position information of the upper material belt or the lower material belt on the transfer table 106. When the moving belt is aligned with the middle material belt, the CCD camera will take a picture of the middle material belt to obtain the position information of the middle material belt, and then adjust the position by rotating the rotating motor 421. After the adjustment, the telescopic motor 420 outputs to make the suction cup 414 drive the upper material belt or the lower material belt to contact the middle material belt. The suction cup 414 will stop moving under the obstruction of the support plate 416, so that the elastic part between the connecting frame 417 and the suction cup 414 will shrink, and push the heating rod 415 to extend from the positioning groove 418 to locate the hot point of the upper material belt or the lower material belt to prevent deviation.

[0070] After the middle layer material tape has completed bonding with the upper layer material tape and the lower layer material tape, the front feeding device 21 and the rear feeding device 22 cooperate to make the middle layer material tape pass between the hot pressing plates on the upper hot pressing mechanism 51 and the lower hot pressing mechanism 52. At this time, the distance between the hot pressing plates is slightly smaller than the sum of the thicknesses of the upper layer material tape, the middle layer material tape and the lower layer material tape, and when the middle layer material tape passes through, the sticky tapes 512 on the upper hot pressing mechanism 51 and the lower hot pressing mechanism 52 will move accordingly to clean the dust on the surface of the bonded material tape.

[0071] After the lamination is completed, the material strip will be removed from the hot pressing unit 5 after hot pressing. At this time, the stripping knife 314 on the post-lamination film stripping device will strip off the protective film on the surface of the upper and lower material strips after lamination and rewind them.

[0072] After the material strip moves out of the hot pressing unit 5, it will enter the receiving mechanism 6 under the traction of the feeding device. When the rear feeding device 22 stops dragging the material strip, the fixed clamping plate 602 will clamp the material strip, so that the cutting cylinder 605 extends and pushes the knife holder 604 closer to the knife seat 603 to cut the material strip. The cut material strip will fall into the receiving frame 606 and be collected. Then the rear feeding device 22 will move toward the installation frame 601, and the material strip will be clamped again by the clamping plate 213 on the dragging frame 212 and moved.

[0073] Because the lamination process of the material strip has a high requirement for cleanliness, the frame 7 is equipped with Fig.10 The protective cover 8 shown in the figure is provided with an air filter 9 on the top of the protective cover 8, and a vacuum system is provided in the frame 7 for providing power for various starting components on the equipment, and the vacuum system is connected to the ventilation duct through the air filter 9.

[0074] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
