Through the coordinated use of the U-shaped rod, the cutting blade, the rectangular block, the connecting rod, and the electric push rod, it can be ensured that the leads of the circuit board components are correctly cut off, avoiding the impact of excessively long or short leads on the soldering quality. This helps to ensure the reliability and durability of the soldering. Compared with traditional manual cutting, it can reduce errors and losses from manual operation, reduce production costs, and reduce the risk of damage to electronic components due to improper manual operation. Moreover, the reciprocating cutting improves the accuracy of circuit board cutting and reduces the occurrence of residual leads on the circuit board.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) The circuit board pin cutting device can clamp the circuit board by using the threaded rod and the L-shaped plate together, ensuring that the circuit board is in a stable position when the pin is cut. The L-shaped plate can also accommodate multiple circuit boards at once, further improving the efficiency of pin cutting.
[0015] (2) The circuit board pin cutting device, through the combined use of the spiral rod, cutting blade, rectangular block, connecting rod and electric push rod, can ensure that the pins of the circuit board are cut correctly, avoid the residual pins that are too long or too short affecting the soldering quality, and help ensure the reliability and durability of the soldering. Compared with traditional manual cutting, it can reduce the errors and losses of manual operation, reduce production costs, and reduce the risk of damage to electronic components due to improper manual operation. Moreover, the reciprocating cutting improves the accuracy of circuit board cutting and reduces the occurrence of residual circuit board pins. Attached Figure Description

[0022] Please see Figure 1-3This utility model provides a technical solution: a circuit board pin cutting device, including a workbench 1, a placement assembly, and a cutting assembly. A pressing plate 5 is provided on the workbench 1, and a mounting bracket 2 is fixedly connected to the top of the workbench 1 to facilitate support of the pressing plate 5. A driving device 3 is fixedly connected to the top of the mounting bracket 2, and a sliding rod 4 is fixedly connected to the free end of the driving device 3. The bottom end of the sliding rod 4 is fixedly connected to the top of the pressing plate 5. Fixing plates 6 are fixedly connected to both the front and rear sides of the workbench 1. A placement assembly is provided on the fixing plate 6, located above the workbench 1. The placement assembly includes a threaded rod 7 and an L-shaped plate 8. The threaded rod 7 is rotatably mounted on the fixing plate 6, and one end of the threaded rod 7 extends to the rear side of a set of fixing plates 6 and is fixedly connected to... The handle, a set of L-shaped plates 8, and a threaded rod 7 are threaded together. The bottom of the L-shaped plates 8 contacts the top of the cutting blade 10, which limits the movement of the L-shaped plates 8. In use, circuit boards are arranged one by one on a set of L-shaped plates 8. Then, the threaded rod 7 is rotated, which moves another set of L-shaped plates 8 until they are in contact with the circuit boards. Then, the drive device 3 is started, and the slide rod 4 on the free end of the drive device 3 moves downward. The downward movement of the slide rod 4 moves the pressing plate 5 downward, which presses the circuit board, making it more secure. Through the cooperation of the threaded rod 7 and the L-shaped plates 8, the circuit boards can be clamped and placed, ensuring that the circuit boards are securely placed during operation. The pins are positioned stably during cutting, and the L-shaped plate 8 allows for the placement of multiple circuit boards at once, further improving the efficiency of pin cutting. The cutting assembly is located below the placement assembly and includes a U-shaped rod 9, cutting blades 10, a rectangular block 11, a connecting rod 12, and an electric push rod 13. Two sets of cutting blades 10 are fixedly connected to the top of the U-shaped rod 9 and arranged opposite each other. The rectangular block 11 is fixedly connected to the bottom of the U-shaped rod 9, and a connecting rod 12 is fixedly connected to one side of the rectangular block 11. The electric push rod 13 is fixedly installed on one side of the assembly plate 14, and the free end of the electric push rod 13 is connected to the connecting rod 12. An opening is provided on the worktable 1 for the rectangular block 11 to pass through. The electric push rod 13 is started by controlling the free end of the electric push rod 13 to drive the connecting rod 12. The connecting rod 12 moves, which in turn moves the rectangular block 11. The rectangular block 11 then moves the loop rod 9, which in turn moves the cutting blade 10. The cutting blade 10 cuts the pins on the circuit board. When the free end of the electric push rod 13 moves the connecting rod 12 backward, it drives the cutting blade 10 to reciprocate, improving the cutting effect of the device. Through the coordinated use of the loop rod 9, cutting blade 10, rectangular block 11, connecting rod 12, and electric push rod 13, the device ensures that the pins of the circuit board are correctly cut, avoiding excessively long or short pins that could affect soldering quality. This helps ensure the reliability and durability of the soldering. Compared with traditional manual cutting, it reduces errors and waste from manual operation, lowering production costs.It also reduces the risk of damage to electronic components due to improper manual operation, and the reciprocating cutting improves the precision of circuit board cutting and reduces the occurrence of residual circuit board pins.
[0023] Furthermore, an assembly plate 14 is fixedly connected to the bottom of the workbench 1, which facilitates the installation of the cutting components.
[0024] Working principle: In use, circuit boards are arranged one by one on a set of L-shaped plates 8. Then, the threaded rod 7 is controlled to rotate. The rotation of the threaded rod 7 drives another set of L-shaped plates 8 to move until the other set of L-shaped plates 8 are in contact with the circuit board. Then, the drive device 3 is started. The slide rod 4 on the free end of the drive device 3 moves downward. The slide rod 4 moves downward, driving the pressing plate 5 downward. The pressing plate 5 presses the circuit board, making the circuit board more stable. Then, the electric push rod 13 is started. The free end of the electric push rod 13 drives the connecting rod 12 to move. The movement of the connecting rod 12 drives the rectangular block 11 to move. The rectangular block 11 drives the loop rod 9 to move. The loop rod 9 drives the cutting blade 10 to move. The cutting blade 10 cuts the pins on the circuit board. When the free end of the electric push rod 13 drives the connecting rod 12 to move backward, it drives the cutting blade 10 to reciprocate and cut, improving the cutting effect of the device.
