Description

Technical Field

[0001] The invention relates to the technical field of FPC roll punching, and in particular to an FPC roll-to-roll four-arm eight-head punching machine. Background Art

[0002] FPC roll refers to a product of flexible printed circuit board provided in the form of roll material. It has high flexibility and bendability and is suitable for electronic devices that require dynamic bending or complex shapes. During the use of FPC roll, it needs to be punched with a punching machine. Its function is mainly used for electrical connection of circuits, installation of components or as a reference point for positioning and fixing. On existing punching machine equipment, a linear track is generally set on the equipment, and then the impact head is driven by the linear track, and then the FPC roll passing through the punching equipment is punched through the corresponding identification system and control system.

[0003] However, when the existing punching equipment punches holes in the FPC coil, the FPC coil is pressed and positioned by two sets of pressure rollers. At the same time, in order to prevent friction between the roll film and the table surface during movement, it is necessary to ensure that the roll film does not contact the table surface. Then, when the punch punches holes in the suspended FPC coil, it is easy to cause the FPC coil to tear, and the punch is prone to overheating during the continuous punching process. In addition, the waste particles generated when punching the FPC coil are easily adhered to the punch by static electricity, thereby affecting the next punching operation. For this reason, an FPC roll-to-roll four-arm eight-head punching machine is proposed. Summary of the invention

Two screw rods 86 are rotatably mounted on the top of the roller frames 84, and the two screw rods 86 penetrate the connecting plate 83 and are threadedly connected to the connecting plate 83.

[0036] A common connecting frame 76 is fixedly installed on the top of the cylinder bodies of the two cylinders 75, a cross frame 72 is fixedly installed on the top of the frame 71, a screw rod 761 is threadedly connected to the cross frame 72, and the bottom end of the screw rod 761 is rotatably connected to the top of the connecting frame 76, a camera 78 is fixedly installed on one side of the cross frame 72, and a prism 781 compatible with the camera 78 is fixedly installed on one side of the movable plate 74, and the prism 781 is located between the two punching mechanisms 77.

[0037] Furthermore, by turning the two screw rods 86, the distance between the corresponding roller frame 1 81 and the roller frame 2 84 can be adjusted, so that the distance between the corresponding guide roller 1 82 and the guide roller 2 85 can be suitable for FPC coils of different thicknesses;

[0038] Alternatively, by turning the screw 1 761, the movable plate 74 slides on the fixed plate 73, and finally by adjusting the distance between the connecting plate 83 and the supporting plate 79 to adjust the distance between the corresponding guide roller 1 82 and the guide roller 2 85 to adapt to FPC coils of different thicknesses.

[0039] A waste chamber 712 is provided on the frame 71, and one side of the waste chamber 712 is opened.

[0040] In this embodiment: when in use, the reel with the FPC coil wound thereon is assembled on the unwinding mechanism 2, and one end of the FPC coil is pulled through the multiple material guide mechanisms 8 and falls on the empty reel assembled on the rewinding mechanism 3. During this process, the FPC coil falls on the top of the multiple guide rollers 1 82 and is under the multiple guide rollers 2 85;

[0041] When punching is required, the camera 78 and the prism 781 cooperate to monitor the position of the FPC coil where the hole needs to be punched, and then the corresponding cylinder 75 is controlled to extend, and the cylinder 75 pushes the cylinder 773 to move downward, and the cylinder 773 pushes the guide cylinder 776 and the type rod 778 to move downward. As the guide cylinder 776 moves downward, the pressure ring 7711 first contacts the FPC coil and presses the FPC coil downward to make it close to the top of the type column 793. Subsequently, as the guide cylinder 776 continues to move downward, the spring 7710 will be compressed, and the pressure ring 7711 and the type column 793 can cooperate to clamp the position of the FPC coil to be punched;

[0042] Then, when the type rod 778 moves down and cooperates with the type hole 7931, the FPC coil can be punched. The particle waste generated by the punching will be pushed by the type rod 778 through the type hole 7931 and fall into the discharge hole 2 7932. When the position relationship between the type rod 778 and the type column 793 is as shown in FIG. Figure 6 As shown, the compressed air supplied by the conduit 7712 will be briefly released and sprayed into the column 792, and then the compressed air will enter the air hole 3 7781 through the air hole 1 774, the air hole 2 775 and the guide tube 776 in sequence. Part of the compressed air sprayed from the bottom opening of the air hole 3 7781 can blow off the granular waste attached to the bottom of the mold rod 778 and make it fall freely, and another part of the compressed air will enter the air groove 7783 from the multiple air holes 4 7782 and be discharged from the connection between the air groove 7783 and the discharge hole 2 7932. In the process of the compressed air flowing through the air hole 3 7781 and each air groove 7783, the mold rod 778 and the mold column 793 can be cooled, and the granular waste falling into the discharge hole 2 7932 will fall into the waste chamber 712 through the discharge hole 1 794 and the feed hole 713.
