Description

Technical Field

[0001] This application relates to the field of PCB manufacturing technology, and specifically discloses an automatic PCB slitting line. Background Technology

[0002] PCB (Printed Circuit Board), also known as printed circuit board or printed circuit board, is an important electronic component. It serves as the support for electronic components and provides electrical connections for them. It is widely used in computers, communication electronic equipment, new energy vehicles, aerospace, semiconductor chip equipment, wind power and photovoltaic green power equipment, and so on. Its applications are very extensive. As long as an electronic product uses integrated circuits, it will use printed circuit boards. Because the products involve many industries, have large demand, and come in a variety of sizes, the most important issues in the production process are capacity and yield. This places higher demands on production equipment, making intelligent automation particularly important.

[0003] In the printed circuit board manufacturing process, in order to maximize output, it is often necessary to use a single layer of multiple boards. Among them, the single-row 2 or single-row 4 process is the most common. The stacking process of printed circuit boards requires the combination of core board, PP, and copper foil. The copper foil is a whole sheet. After the stacking and pressing is completed, regardless of whether it is a single-row 2 or single-row 4 board, the excess edges of the copper foil need to be cut off manually. The speed is relatively slow and the output is not high. In order to improve the production efficiency and quality of customers, this application specifically develops a double-roll copper foil cutting and stacking equipment. Utility Model Content

[0030] Example

[0031] To address the issues of slow speed and low production capacity in existing technologies that require manual trimming of excess copper foil around PCB boards, referenced... Figures 1-3 As shown, in some embodiments, this application discloses an automatic PCB board slitting line, including a copper foil four-sided cutting mechanism 10, a whole board slitting mechanism 20, and a double-material stacking mechanism 30;

[0032] The copper foil four-sided cutting mechanism 10 includes a belt conveyor 11 arranged along a first direction, a vision positioning unit 12 mounted above the belt conveyor 11, an XYZ axis drive unit 13 mounted on the belt conveyor 11, and a cutting unit 14 mounted on the XYZ axis drive unit 13. In specific implementation, the stacked PCB board is first placed on the belt conveyor 11, then the vision positioning unit 12 takes pictures and positions it, and finally, according to the guidance of the vision positioning unit 12, the XYZ axis drive unit 13 drives the cutting unit 14 to move along the X-axis, Y-axis and Z-axis to cut the excess material around the copper foil.

[0033] The board slitting mechanism 20 includes a first roller line 21 connected along the first direction at the end of the belt conveyor line 11 and a slitting unit 22 located at the end of the first roller line 21. When the copper foil cutting of the PCB board is completed, the first roller line conveys the PCB board to the slitting unit 22, and then the slitting unit 22 cuts the PCB board into two pieces.

[0034] The dual-material stacking mechanism 30 includes a second roller line 31 connected to the end of the cutting unit, at least one temporary storage rack 32 arranged on one side of the second roller line 31 in a second direction, and two suction cranes 33 erected above the second roller line 31 and the temporary storage rack 32 and capable of shuttling. When the cutting unit 22 cuts the PCB board into two pieces, the second roller line 31 transports the two cut PCB boards to its end one after another, and the two suction cranes 33 successively lift and transport the two PCB boards onto the temporary storage rack 32 for stacking.

[0035] As a specific embodiment, the visual positioning unit 12 of this application includes a support rod 121 disposed on one side of the belt conveyor 11 in the second direction, a support plate connected to the top of the support rod 121 and extending toward the belt conveyor 11, and a visual positioning camera 122 mounted on the support plate. When the stacked PCB board is located on the belt conveyor 11, the visual positioning camera 122 will take a picture of the PCB board to determine its location.

[0036] As a specific embodiment, the XYZ axis drive unit 13 of this application includes an X-axis servo moving module 131 disposed on both sides of the belt conveyor 11 in the second direction, a first Y-axis servo moving module 132 connected above the X-axis servo moving module 131, and a Z-axis servo moving module 133 connected to the first Y-axis servo moving module 132. Correspondingly, the cutting unit 14 of this application includes a lifting support 141 connected to the Z-axis servo moving module 133, a first motor 142 disposed above the lifting support 141, and a motor 142 disposed at the bottom of the lifting support 141 and connected to the first motor. In a specific implementation, the cutting steel blade 143 connected to the output shaft of the machine 142 is driven by the X-axis servo movement module 131 to move the first Y-axis servo movement module 132 along the X-axis direction, the first Y-axis servo movement module 132 to move the Z-axis servo movement module 133 along the Y-axis direction, and the Z-axis servo movement module 133 to move the lifting support 141 along the Z-axis. When the cutting steel blade 143 contacts the periphery of the copper foil, it can cut it. In addition, when the cutting steel blade 143 has finished cutting the remaining material on one side of the copper foil, the first motor 142 drives the cutting steel blade 143 to rotate and change direction.

[0037] To prevent the first roller line 21 or the second roller line 31 from shifting during the movement of the PCB board, this application provides a board alignment mechanism 40 in both the second roller line 31 and the second roller line 31. The board alignment mechanism 40 includes a bidirectional servo moving module 41, two positioning plates 43 connected to the two drive units of the bidirectional servo moving module 41 by connecting rods 42 passing through the roller gap, and several arc-shaped grooves 431 formed at the bottom of the two positioning plates 43 and cooperating with the rollers. When the PCB board moves on the first roller line 21 or the second roller line 31, the corresponding bidirectional servo moving module 41 will simultaneously drive the two positioning plates 43 to move closer together. At this time, the PCB board will be positioned at the set position.

[0038] As a specific embodiment, the slitting unit 22 of this application includes a knife holder 221 located at the end of the first roller liner 21, a lower knife 222 located below the knife holder 221, and an upper knife 226 slidably located above the knife holder 221 and driven to rise and fall by a second motor 223, a cam 224, and a connecting rod 225. When one half of the PCB board is located on the first roller liner 21 and the other half is located on the second roller liner 31, the second motor 223, the cam 224, and the connecting rod 225 work together to drive the upper knife 226 to descend. When it cooperates with the lower knife 222, the PCB board can be slid into two pieces.

[0039] In order to prevent the PCB board from falling off the second roller line 31 and being lifted by the suction machine 33, this application provides a blocking block 311 at the end of the second roller line 31 to block the entire board. When the tail end of the PCB board comes into contact with the blocking block 311, it can restrict the board from moving one step, thereby achieving the blocking function.

[0040] In a preferred embodiment, the present application provides two temporary storage racks 32, which are located on both sides of the second roller line 31 in the second direction. In actual use, if a set number of PCB boards are stacked on one of the temporary storage racks 32, the two suction cranes 33 will move the subsequently cut PCB boards to the other temporary storage rack 32. In this way, the continuous operation of the entire equipment will not be affected, and it has high use value.

[0041] Based on the above preferred method, the following are the configuration methods of the two suction lifters 33 in this application:

[0042] This application provides gantry 34 on the outer sides of two temporary storage racks 32, and two suction lifters 33 are arranged between the two gantry 34 along a first direction. Each suction lifter 33 includes a second Y-axis servo movement module 331 located between the two gantry 34, a lifting cylinder 332 connected to the second Y-axis servo movement module 331, a frame 333 connected to the piston rod of the lifting cylinder 332, and several pneumatic suction cups 334 located at the bottom of the frame 333. During the PCB stacking process, the second Y-axis of one of the suction lifters 33... The servo moving module 331 drives the lifting cylinder 332 to move above the end of the second roller line 31. After it is in position, the lifting cylinder 332 drives the frame 333 to descend and the pneumatic suction cups 334 pick up the PCB board at the end of the second roller line 31. After that, the second Y-axis servo moving module 331 drives the lifting cylinder 332 to move above the temporary storage rack 32. After it is in position, the lifting cylinder drives the frame 333 to descend and the PCB board will be stacked on the temporary storage rack 32 when the pneumatic suction cups 334 stop picking up the PCB board.

[0043] After the pneumatic suction cups 334 included in the aforementioned suction and hoisting machine 33 pick up the PCB board, the second roller conveyor 31 transports another PCB board to the end of the second roller conveyor 31. At the same time, the second Y-axis servo moving module 331 included in another suction and hoisting machine 33 drives the lifting cylinder 332 to move above the end of the second roller conveyor 31. After it is in position, the lifting cylinder 332 drives the frame 333 to descend, and the pneumatic suction cups 334 pick up the PCB board at the end of the second roller conveyor 31. After that, the second Y-axis servo moving module 331 drives the lifting cylinder 332 to move above the temporary storage rack 32. After it is in position, the lifting cylinder drives the frame 333 to descend, and when the pneumatic suction cups 334 stop picking up the PCB board, the PCB board will be placed on the temporary storage rack 32.

[0044] It should be noted that the two frames 333 in this application should be set to be staggered in the initial state, one high and one low, so as to avoid mutual interference during operation and form a shuttle movement.
