Description

Technical Field

[0001] The invention relates to the technical field of circuit board processing, in particular to a punching device used for circuit board processing. Background Art

[0002] Punching holes in circuit boards plays many important roles in electronic manufacturing. It is a key step in realizing circuit functions, fixing components, optimizing heat dissipation, providing connection interfaces, and improving production efficiency. Therefore, in the design and manufacturing process of circuit boards, it is necessary to fully consider the needs and process requirements of punching holes to ensure the quality and performance of the final product. Circuit boards are often divided into rigid circuit boards and flexible circuit boards according to their uses. When punching holes in flexible circuit boards, workers need to use tape to stick the flexible circuit boards to be punched to fix the flexible circuit boards in the punching area. Because the accuracy of the punching position affects the quality of the circuit board, the accuracy of the fixed position of the flexible circuit board is required to be high during the positioning of the flexible circuit board.

[0003] The patent document with announcement number CN214046187U discloses a flexible circuit board punching machine, including an external structure, the upper end of the external structure is fixedly connected with a clamping mechanism for clamping the flexible circuit board, the inner fixed connection of the clamping mechanism is a locking structure for fixing the clamping mechanism, the upper end of the external structure is fixedly connected with a transmission mechanism for driving the punching mechanism to move, and the upper end of the external structure is slidably connected with a punching mechanism for punching the flexible circuit board; the flexible circuit board is clamped by the clamping mechanism, and the circuit board is locked by the locking structure, and the punching mechanism is driven by the transmission mechanism to automatically position and punch, which reduces the probability of damage to the circuit board during punching, and at the same time increases the punching speed and the punching efficiency. However, the patent still has the following problems in actual use:

[0004] The punching machine achieves the effect of limiting the position of the flexible circuit board by setting a clamping mechanism, and cooperates with the spring and elastic pad set on the outside of the drill bit to achieve the effect of automatic punching of the flexible circuit board. However, since the punching positions of the circuit board are relatively close, the elastic pad needs to be completely separated from the circuit board during the lifting process of the drill bit, otherwise the elastic pad will push the flexible circuit board to move and reposition the punching position, resulting in the drill bit needing to be repeatedly lifted to a higher distance when punching holes in the flexible circuit board, which takes more time and reduces the punching efficiency of the circuit board.

[0005] Therefore, we propose a punching device for circuit board processing to solve the above-mentioned problems. Summary of the invention

[0045] Working principle: Figure 1-Figure 9As shown, when using the device, first, turn on the adjusting motor 403, so that the adjusting motor 403 drives the adjusting screw 402 to rotate, so that the adjusting screw 402 drives the gantry 401 to move, and at this time the gantry 401 drives the rotating shaft 405 to move through the vertical groove 404, so that the two ends of the rotating shaft 405 slide in the moving grooves 303 at the lower ends of the positioning seat 1 302 and the positioning seat 2 310 respectively.

[0047] Secondly, move the rotating shaft 405 to the top of the pressing block 304, and control the extension of the cylinder 307 so that the cylinder 307 drives the pressing block 304 to rise at the fixed rod 306 through the lifting slot 305, so that the baffle 308 rises in the shrinking slot 309, and at the same time, push the rotating shaft 405 upward in the moving slot 303, so that the punched circuit board can be taken out, and control the guide motor 502 so that the guide motor 502 drives the guide screw 501 to rotate, so that the guide screw 501 controls the moving block 503 to move in the guide slot 507, so that the position of the guide block 506 is adjusted, and the spacing between the guide blocks 506 is suitable for the circuit board to be punched.

At this time, the rotating shaft 405 presses the surface of the circuit board, and the pressing frame 406 and the circuit board are pressed. The surfaces of the boards are separated, and when the gantry 401 moves to the other end of the circuit board, by turning the knob 415, the threaded rod 414 drives the threaded block 413 to rise in the make way groove 416. When the threaded block 413 is separated from the power rod 418, the connecting rod 412 and the adjusting block 411 can be contracted to one side of the power rod 418 under the action of the extrusion spring 417, so that the pressing frame 406 presses the circuit boards on both sides of the rotating shaft 405, and then the circuit board can be punched through the punching end 1 on the positioning frame 2.
