[0002] Pin headers are generally widely used in the connection of PCB boards. They are usually paired with connectors such as female headers and wire ends. Pin headers are widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Their function is to act as a bridge between blocked or isolated circuits within the circuit, and to take on the task of current or signal transmission. Pin header cutting is an important step in the production process of pin headers. When making pin headers, you first need to select suitable metal materials and cut them into blanks of suitable lengths. These blanks are usually strips ranging from several millimeters to tens of centimeters.

[0003] The cutting device mainly uses a cutting knife to cut the pin header, and can cut the entire pin header into multiple pieces. However, the number of pin headers cut is relatively large, and the staff is often required to manually pick up all the pin headers for unloading. This process is time-consuming. Therefore, it is particularly important to design an adjustable pin header cutting device. After the pin header is cut, some of the pin headers can be fed downward in turn to save time.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, a screw rod 10 is provided inside the pushing frame 9, a parallel plate 12 is provided on one side of the vertical plate 13, the output shaft of the micro motor 5 is transmission-connected to one end of the screw rod 10, one side of the push plate 14 is fixedly connected to the other side of the vertical plate 13, the bottom surface of the push plate 14 is in contact with the surface of the cutting seat 1, and a plurality of reinforcement seats 15 are provided at the bottom of the cutting seat 1. The adjustable needle arrangement and cutting device of the utility model is provided with a moving rod 2, a moving block 3, a cutting frame 7 and a parallel plate 12. When the micro motor 5 is started, it drives the straight rack 4 meshing with it to move forward and backward, and will also drive the displacement block 11 to move left and right at one end of the screw rod 10.

[0026] Working principle: Pin headers are generally widely used in the connection of PCB boards. They are generally paired with female pins and line end connectors. Pin headers are widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Their function is to act as a bridge between the blocked part and the isolated circuit in the circuit, and to take on the task of current and signal transmission. Pin header cutting is an important step in the production process of pin headers. When making pin headers, you first need to select a suitable metal material and cut it into blanks of suitable length. These blanks are usually strips of several millimeters to tens of centimeters. The pin headers are placed on the top of the cutting seat 1 in turn, and the pin headers are limited by a limiting mechanism. The limiting mechanism includes a positioning claw to keep the pin header stable. Subsequently, the staff starts the micro motor 5, which will drive the gear 6 to rotate synchronously. When the gear 6 rotates clockwise, the two moving blocks 3 can move backward at one end of the corresponding moving rod 2, which will drive the straight rack 4 meshing with it to move to a position close to the vertical plate 13, and drive the cutting knife 8 to move backward. The surface of the cutting knife 8 gradually contacts with the row of pins, and the whole row of pins can be cut into multiple pieces. At this time, through the movement of the displacement block 11, the push plate 14 will also be located on one side of the cutting seat 1, which is convenient for the cutting knife 8 to cut the row of pins. After the row of pins is cut, the straight rack 4 moves forward, driving the displacement block 11 to move at one end of the screw rod 10, and also driving the push plate 14 to move to the right. The cutting knife 8 gradually moves away from the cutting seat 1, and the push plate 14 gradually approaches the cut row of pins, so that the whole row of pins can be cut into multiple pieces. The row of needles is pushed, and some of the row of needles can fall down from the other side of the cutting seat 1. The movement of the displacement block 11 will drive the parallel plate 12 and the vertical plate 13 to move, and also drive the push plate 14 to move. The start of the micro motor 5 drives the straight rack 4 meshing with it to move back and forth, and will also drive the displacement block 11 to move left and right at one end of the screw rod 10. Therefore, after the row of needles is cut, the position of the push plate 14 can be adjusted to transport the sheared row of needles and unload the needles.
