[0002] A circuit board, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Almost every electronic device, from small items like electronic watches and calculators to large systems like computers, communication devices, and military weapons, uses circuit boards to enable electrical interconnection between integrated circuits and other electronic components. A circuit board consists of an insulating base, connecting wires, and solder pads for mounting and soldering electronic components, serving the dual function of conducting conductive lines and acting as an insulating base.

[0003] Flexible circuit boards (PCBs) are a type of circuit board that differs from conventional circuit boards in that they can be bent and twisted. However, precisely because of this characteristic, flexible circuit boards will experience a certain degree of springback and warping during punching, and the cut edges will often warp due to incomplete clamping, leading to inaccurate punching or damage to the circuit board, which greatly affects product quality.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0018] like Figures 1 to 6 As shown, this utility model provides a flexible circuit board punching device 100, which includes a processing table 10, a mounting frame 20, a feeding assembly 30, a pre-pressing assembly 40, and a punching assembly 50. The processing table 10 is provided with a feeding groove 11. The mounting frame 20 stands on the processing table 10 and is located above the feeding groove 11. The feeding assembly 30 is installed in the feeding groove 11. The pre-pressing assembly 40 is installed on the processing table 10 and is located above the feeding assembly 30. The punching assembly 50 is installed on the mounting frame 20 and is located above the pre-pressing assembly 40. It is understood that this utility model also includes several electric drive structures, pneumatic drive structures, etc., which are all conventional technologies in the field and will not be described in detail here.

[0019] The feeding assembly 30 includes two sets of feeding rollers 31 and a conveyor belt 32. The two sets of feeding rollers 31 are respectively installed at both ends of the feeding trough 11, and the conveyor belt 32 is sleeved on the two sets of feeding rollers 31 and can be rotated by the feeding rollers 31. The feeding assembly 30 with the conveyor belt 32 structure can quickly load and unload flexible circuit boards, thereby realizing high-efficiency punching processing of circuit boards.

[0020] The pre-pressing assembly 40 includes a fixing plate 41, a pre-pressing plate 42, and a plurality of first elastic pressure rods 43. The fixing plate 41 is mounted above the middle of the feeding trough 11, and the middle of the fixing plate 41 is also provided with a punching window 411 that runs vertically through it. The pre-pressing plate 42 is located below the fixing plate 41 and above the feeding assembly 30. The pre-pressing plate 42 is also provided with a plurality of punching through holes 421. The plurality of first elastic pressure rods 43 are all inserted through the fixing plate 41, and the lower ends of the plurality of first elastic pressure rods 43 are also engaged with the pre-pressing plate 42.

[0021] With the addition of the pre-pressing component 40, before punching the flexible circuit board, the punching component 50 first presses down the first elastic pressure rod 43, which in turn drives the pre-pressing plate 42 to press down synchronously until the pre-pressing plate 42 is pressed against the upper surface of the flexible circuit board, thus achieving the limiting and fixing of the flexible circuit board. Under the pressure of the pre-pressing plate 42, the flexible circuit board will not experience problems such as springback or warping during punching, ultimately making the punching process more precise and reliable. In addition, the snap-fit ​​connection design between the first elastic pressure rod 43 and the pre-pressing plate 42 allows for the replacement of different pre-pressing plates 42, thereby handling the punching process of flexible circuit boards of different specifications.

The movable bushings 422 are elastically hinged to the side of the pre-pressing plate 42, and the flattening rollers 423 are engaged between the movable bushings 422 and can rotate. The addition of flattening rollers 423 on both sides of the pre-pressing plate 42 allows the flexible circuit board to be flattened by the flattening rollers 423 during the feeding process, thereby ensuring that the flexible circuit board will not be affected by wrinkles during the punching process, thus ensuring that the final processing effect is not affected.

[0023] The punching assembly 50 includes a punching cylinder 51, a punching plate 52, a plurality of second elastic pressure rods 53, and a plurality of punching blades 54.

The punching assembly 50 is designed with multiple sets of punching blades 54, enabling simultaneous punching of multiple sections of flexible circuit boards, further improving the punching efficiency of the punching device.

[0024] The stamping plate 52 is provided with an adjusting slide groove 521, and the punching cutter 54 includes a cutter holder 541 and a blade 542. The two ends of the cutter holder 541 are respectively engaged and slidably adjusted within the adjusting slide groove 521, and the blade 542 is mounted on the bottom of the cutter holder 541.
