Description

Technical Field

[0001] The invention belongs to the technical field of flexible circuit board punching and correction, and in particular relates to a correction and detection structure for flexible circuit board punching. Background Art

[0002] Flexible circuit board, also known as flexible circuit board, is a printed circuit board with high flexibility and bendability. It is made of a flexible insulating substrate with copper foil circuits attached. Compared with traditional rigid circuit boards, flexible circuit boards have many unique advantages. The correction of the flexible circuit board during the punching process is a crucial operation. It is mainly used to ensure the precision and accuracy of the punching to reduce the scrap rate and improve product quality.

[0003] Due to the soft texture of flexible printed circuits, they are prone to curling during punching and shearing, which damages the printed circuit board after punching and shearing, increasing the scrap rate of the printed circuit board. In addition, common flexible printed circuit board deflection correction equipment moves the printed circuit board for correction, which can also cause damage to the printed circuit board during movement, resulting in damage to the printed circuit board during the correction process. In view of this, we propose a deflection correction detection structure for flexible printed circuit board punching. Summary of the Invention

[0090] Example 10:

[0091] This embodiment provides a correction and detection structure for punching flexible circuit boards. In addition to the technical solutions of the above embodiments, it also has the following technical features: the top of the large suction cup 5, the tops of the several small suction cups 7, and the top of the fixing base 2 are all located on the same horizontal plane.

[0092] Here, it is ensured that the flexible printed circuit board can be stably placed on the large suction cup 5 and the plurality of small suction cups 7 .

[0093] Working principle: When in use, personnel can first place the flexible circuit board on the top of the fixing seat 2. At this time, the flexible circuit board will be located on the top of the large suction cup 5 and several small suction cups 7. Then personnel can start the air pump 9. The air pump 9 can extract the air in the suction pipe 4 and discharge it to the outside through the air outlet slot 8. The suction pipe 4 will also suck the air in the large suction cup 5 into the suction pipe 4. At the same time, the suction pipe 4 can also respectively extract the air in the several small suction cups 7 through the several suction pipes 2 6, so that negative pressure is formed in the large suction cup 5 and the several small suction cups 7. The flexible circuit board can be adsorbed on the large suction cup 5 and the several small suction cups 7, thereby fixing the flexible circuit board. Under the adsorption effect of the several small suction cups 7, the flexible circuit board can be prevented from curling, ensuring that the subsequent punching and shearing will not deviate, thereby reducing the scrap rate.

[0094] Then the personnel can adjust the cutting angle according to the fixed position of the flexible circuit board, so as to achieve the effect of correction. First, start the motor 2 18. The output shaft of the motor 2 18 will drive the gear 17 to rotate. Under the action of meshing, the rotation of the gear 17 will roll on the gear ring 20, thereby passively driving the rectangular block 12 to rotate. At the same time, the rotation of the rectangular block 12 will drive the sliding block 11 to slide in the annular groove 10. The rotation of the rectangular block 12 will also drive the circular frame 22 and the punching shears 29 to rotate until the punching shears 29 rotates to the direction in which the flexible circuit board needs to be punched and sheared. Turn off the motor 2 18, and then the personnel can start the motor 16. The output shaft of the motor 16 will drive the threaded rod 15 to rotate. Under the action of the thread, the rotation of the threaded rod 15 will drive the slider 14 to move. The movement of the slider 14 will drive the circular frame 22 to move, so that the circular frame 22 approaches the flexible circuit board. At the same time, the circular frame 22 will also drive the punching shears 29 to approach the flexible circuit board until When the punching shears 29 moves to the position where the flexible circuit board needs to be punched, the motor 16 is turned off, and then the personnel can start the two motors 3 27 at the same time. The output shafts of the two motors 3 27 will respectively drive the two bidirectional threaded rods 26 to rotate. Under the action of the threads, the rotation of the two bidirectional threaded rods 26 will drive the two clamping plates 24 to move closer to each other until the two clamping plates 24 clamp one side of the flexible circuit board. At the same time, under the protection of the two rubber pads 25, it can be ensured that the flexible circuit board will not be damaged during the clamping process. Finally, the electric push rod 28 is started again, and the output shaft of the electric push rod 28 will drive the punching shears 29 to move downward. The downward movement of the punching shears 29 can punch and shear the flexible circuit board, ensuring that the punching angle of the punching shears 29 can be adjusted at will according to the fixed position of the flexible circuit board, thereby correcting the deviation and punching of the flexible circuit board, ensuring that any position on the side of the flexible circuit board can be punched and sheared automatically and accurately, and ensuring the quality of the flexible circuit board after punching and shearing.
