Description

Technical Field

[0001] The utility model relates to the field of FPC circuit board processing, and specifically relates to an FPC circuit board blanking and feeding device. Background Technique

[0002] An FPC circuit board, that is, a flexible printed circuit board, abbreviated as a flexible board, is a circuit board made of a flexible copper clad laminate; as a medium for signal transmission, it is widely used in the connection of electronic products; compared with traditional rigid PCB boards, FPCs have the characteristics of high wiring assembly density, good bendability, and flexible processes.

[0003] In the blanking process of FPC circuit boards, feeding is a key link. Before feeding, it is necessary to ensure that the size, thickness, and surface quality of the FPC material meet the processing requirements. At the same time, the material also needs to be appropriately pretreated.

[0004] When the existing FPC circuit boards are blanked and fed, they are usually adsorbed and fixed by a suction cup. In production and observation, it is found that due to the complex shape of the FPC circuit board, it is difficult for the suction cup to stably adsorb the surface of the FPC circuit board, which will cause the FPC circuit board to shake during the feeding process.

[0011] Preferably, a plurality of guide plates are fixedly connected to the inner side wall of the suction cup; the guide plates and the circular holes are correspondingly arranged; the guide plates are of an arc-shaped structure; when the vertical pole passes through the circular hole, the vertical pole will pass through the guide plate, and because the surface of the guide plate is of an arc-shaped structure, the vertical pole will move along the surface of the guide plate and enter the circular hole, thereby improving the stability of the docking between the vertical pole and the circular hole.

At the same time, the trachea 15 is externally connected to an air pump so that the air flow inside the suction cup 13 will flow towards the trachea 15. At this time, the air flow at the round holes 14 will enter the inside of the suction cup 13 through the hole plate 18 and the elastic cloth 19, making the surface of the hole plate 18 in a negative pressure state. When the suction cup 13 and the flexible circuit board approach, the flexible circuit board will be adsorbed on the bottom of the suction cup 13 under the negative pressure at the round holes 14.

[0030] See also Figure 2As shown, a plurality of guide plates 5 are fixedly connected to the inner side wall of the suction cup 13; the guide plates 5 and the round holes 14 are correspondingly arranged; the guide plates 5 are arc-shaped structures; when the vertical rod 22 passes through the round hole 14, the vertical rod 22 will pass through the guide plate 5.

At the same time, the air pipe 15 is connected to an external air pump so that the air flow inside the suction cup 13 will flow to the air pipe 15.

When the suction cup 13 and the flexible circuit board are close to each other, the flexible circuit board will be adsorbed on the bottom of the suction cup 13 under the action of the negative pressure at the circular hole 14. At the same time, the flexible circuit board will come into contact with and squeeze the orifice plate 18, and the orifice plate 18 will transmit the pressure to the first spring 17 so that the first spring 17 is in a compressed state, and then the first spring 17 will apply elastic force to the orifice plate 18 so that the orifice plate 18 is close to the surface of the flexible circuit board, increasing the contact area between the suction cup 13 and the flexible circuit board. After the suction cup 13 adsorbs and fixes the flexible circuit board, it will reach the blanking area under the transportation action of the cylinder 12 and the transportation component 1, and finally the suction cup 13 can stop adsorbing or the squeezing component 16 can be used to release the flexible circuit board for blanking processing; the second spring 24 will be in a stretched state when working normally. When the suction force at the orifice plate 18 is too strong, the flexible circuit board will adhere to the bottom of the suction cup 13. At this time, the staff can release the fixing plate 25 by adjusting the component 26, and the slide plate 2 and the slide bar 23 will slide along the suction cup 13 under the elastic force of the second spring 24, and the slide plate 2 will carry the vertical rod 22 moves together so that the vertical rod 22 passes through the circular hole 14 and squeezes the surface of the flexible circuit board, and the flexible circuit board will be separated from the bottom of the suction cup 13 under the squeezing effect of the vertical rod 22; the staff can pull out the vertical plate 3 to separate the fixing plate 25 and the insertion rod 32 from the fixing effect of the vertical plate 3, so that the slide plate 2 and the vertical rod 22 will squeeze the flexible circuit board under the elastic force of the second spring 24, and after the separation is completed, the fixing plate 25 can be pulled again and the vertical plate 3 is passed through the insertion rod 32 and the fixing plate 25 to fix it; when the fixing plate 25 moves under the elastic force of the second spring 24, the second magnet 42 will move with the fixing plate 25 and approach the first magnet 4, and the second magnet 42 will be subjected to the repulsive force of the first magnet 4, so that The fixed plate 25 is subjected to additional resistance when moving, thereby reducing the moving speed of the skateboard 2 and the vertical rod 22; when the vertical rod 22 passes through the circular hole 14, the vertical rod 22 will pass through the guide plate 5, because the surface of the guide plate 5 is an arc-shaped structure, so that the vertical rod 22 will move along the surface of the guide plate 5 and enter the inside of the circular hole 14; when the skateboard 2 and the vertical rod 22 slide along the suction cup 13, the length of the telescopic rod 6 will also change accordingly, and the telescopic rod 6 will provide additional support for the skateboard 2 when moving, thereby improving the stability of the skateboard 2 when moving; when the orifice plate 18 contacts the flexible circuit board, the buffer pad 7 will first contact the flexible circuit board, because the buffer pad 7 is a flexible material, so that the buffer pad 7 will absorb the impact generated when the orifice plate 18 contacts the flexible circuit board.
