Description

Technical Field

[0001] This utility model relates to the field of flexible printed circuit board processing technology, and in particular to a punching device for processing flexible printed circuit boards. Background Technology

[0002] Flexible printed circuit boards are printed circuits made of flexible insulating substrates. During the processing of flexible printed circuit boards, they need to be punched, so a punching device for processing flexible printed circuit boards is used.

[0003] To address this, patent CN219599647U discloses a flexible printed circuit board punching device, belonging to the field of circuit board processing technology. It includes a base, with a base plate fixedly installed at the center of the top of the base. Four sets of baffles are arranged on the outer side of the base plate. The baffles are movable, and an adjustment component is provided between the baffles and the base. The baffles are installed on the top of the base via the adjustment component. Discharge grooves are provided on both sides of the base and on the surface of the base plate. This invention uses four sets of baffles to fix the circuit board to be punched on the top of the base plate. The user can adjust the spacing between the four sets of baffles according to the size of the circuit board, allowing the four sets of baffles to adapt to the positioning requirements of circuit boards of different sizes. The position of the baffles can be adjusted by the adjustment component, and after adjustment, the position of the baffles can be locked and fixed by the positioning rod. This device is convenient to use and can adapt to the positioning requirements of circuit boards of different sizes.

[0004] Although the flexible printed circuit board punching device mentioned above can adapt to the positioning requirements of circuit boards of different sizes, its applicability is low because it is inconvenient to push and feed the flexible printed circuit boards. Utility Model Content

[0005] The purpose of this invention is to provide a punching device for processing flexible printed circuit boards, in order to solve the defect of existing punching devices for processing flexible printed circuit boards being inconvenient to push.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a punching device for processing flexible printed circuit boards, including a worktable;

[0007] A bracket is fixed at the corner of the bottom of the workbench, and an adjustment structure is fixed on both sides of the top of the workbench.

[0008] A fixing frame is fixed to one side of the top of the workbench, and a pre-compression structure is provided inside the fixing frame;

[0009] The top of the workbench is provided with a pushing structure, which includes a slide groove that runs through the inside of the workbench. A slide plate runs through the inside of the slide groove, and a push plate is fixed to the top of the slide plate. A threaded rod is provided on one side below the slide groove. Vertical plates are fixed to the bottom of the workbench at both ends of the threaded rod, and a movable seat is threaded to the outside of the threaded rod.

[0010] When using this device, the push structure facilitates material feeding, thereby improving the applicability of the punching device for flexible printed circuit board processing; the adjustment structure facilitates guidance, thereby improving the ease of use; and the pre-pressing structure facilitates punching, thereby improving the stability.

[0011] Preferably, the adjustment structure includes a support plate, a first electric push rod, a guide rod, a fixed frame, and a guide roller. The support plate is fixed to both sides of the top of the worktable. The first electric push rod runs through the interior of each support plate. A fixed frame is fixed to one end of each first electric push rod. A guide roller is rotatably connected to one side of each fixed frame. Guide rods run through the interior of the support plates on both sides of the first electric push rod. The guide rods enhance the stability of the fixed frame during movement, and the moved fixed frame drives the guide roller to move.

[0012] Preferably, one end of the guide rod is fixedly connected to one side of the fixed frame, and the guide rod and the support plate form a sliding structure. Under the action of the guide roller, the flexible printed circuit board can be guided, thereby preventing the flexible printed circuit board from shifting during movement.

[0013] Preferably, the pre-compression structure includes a second electric push rod, a movable plate, a pre-compression frame, a cutter, a movable rod, a return spring, a baffle, and a guide plate. The second electric push rod passes through the top of the fixed frame, and a movable plate is fixed to the bottom end of the second electric push rod. A cutter is fixed to the bottom end of the movable plate. Movable rods are evenly inserted through both sides of the interior of the movable plate. A pre-compression frame is fixed to the bottom end of each movable rod, and a baffle is fixed to the top end of each movable rod. A return spring is sleeved on the outer side of each movable rod at the bottom end of the movable plate, and guide plates are fixed to both sides of the movable plate. Under the action of the guide plate, the stability of the movable plate during movement is enhanced. Under the action of the ball bearings, the friction between the guide plate and the fixed frame is reduced. After moving, the movable plate first drives the pre-compression frame to move, so that the bottom end of the pre-compression frame abuts against the top end of the flexible printed circuit board.

[0014] Preferably, the movable rod and the movable plate form a sliding structure. A guide groove is provided inside the fixed frame on one side of the guide plate. The guide plate and the fixed frame form a sliding structure through the guide groove. A ball bearing is uniformly rotatably connected to one side of the guide plate, and the guide plate and the fixed frame contact each other through the ball bearing. As the cutter moves downwards, the bottom end of the pre-pressure frame always abuts against the top end of the flexible printed circuit board. Under the action of the pre-pressure frame, displacement of the flexible printed circuit board is prevented. Under the action of the cutter, the flexible printed circuit board can be punched.

[0015] Preferably, a slide rod extends through one side of the interior of the movable seat, and a drive motor is mounted on the outer wall of the vertical plate at one end of the threaded rod. Under the action of the slide rod, the movable seat is prevented from rotating along with the threaded rod, and the moved movable seat will drive the push plate to move via the slide plate.

[0016] Preferably, the bottom end of the sliding plate is fixedly connected to the top end of the movable seat, the sliding plate and the worktable form a sliding structure through a sliding groove, one end of the threaded rod extends to the outside of the vertical plate and is fixedly connected to the output end of the drive motor, the sliding rod and the movable seat form a sliding structure, and both ends of the sliding rod are fixedly connected to one side of the vertical plate. This allows the push plate to move the flexible printed circuit board, thereby facilitating the feeding of the flexible printed circuit board.

[0017] The punching device for processing flexible printed circuit boards provided by this utility model has the following advantages:

[0018] By setting up a pushing structure, the moving seat is prevented from rotating with the threaded rod under the action of the slide bar. After the moving seat moves, it will drive the push plate to move through the slide plate, so that the push plate can drive the flexible printed circuit board to move, thereby facilitating the feeding of the flexible printed circuit board. This realizes the function of easy feeding of the device, thereby improving the applicability of the punching device for processing flexible printed circuit boards in use.

[0019] By setting an adjustment structure, the stability of the fixed frame during movement is enhanced under the action of the guide rod. The moved fixed frame drives the guide roller to move, and under the action of the guide roller, the flexible printed circuit board can be guided, thereby preventing the flexible printed circuit board from deviating during movement. This realizes the guiding function of the device, thereby improving the convenience of using the punching device for processing flexible printed circuit boards.

[0020] By incorporating a pre-pressing structure, the stability of the movable plate during movement is enhanced under the action of the guide plate. The friction between the guide plate and the fixed frame is reduced by the action of the ball bearings. The movable plate, after moving, first drives the pre-pressing frame to move, causing its bottom end to contact the top end of the flexible printed circuit board. As the cutter moves downwards, the bottom end of the pre-pressing frame remains in contact with the top end of the flexible printed circuit board. The pre-pressing frame prevents displacement of the flexible printed circuit board, and the cutter enables punching of the flexible printed circuit board, thus facilitating punching and improving the stability of the punching device for flexible printed circuit board processing during use.
