[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0029] like Figures 1 to 5As shown, a lead-out pin cutting device includes a first cutting plate 1, a second cutting plate 2 and a driving device 5. The first cutting plate 1 is provided with a socket with two ends passing through it. A product placement position is provided on the surface of the first cutting plate 1 corresponding to one end of the socket, and a blanking hole 3 is provided on the second cutting plate 2 corresponding to the other end of the socket. When a product 11 (a relay is used as an example in this embodiment) is placed in the product placement position, the lead-out pin 4 of the product 11 extends into the socket and the position of the lead-out pin 4 to be cut is located at the junction of the socket and the blanking hole 3. The driving device 5 provides a driving force for the first cutting plate 1 or the second cutting plate 2 to cause the socket and the blanking hole 3 to be misaligned so as to cut off the lead-out pin 4. The product placement position limits the depth of the lead-out pin 4 of the product 11 inserted into the socket, thereby ensuring the consistency of the cut length of the lead-out pin 4 of the product 11, and has a smaller length error compared with manual cutting with diagonal pliers. The driving device 5 includes but is not limited to a pneumatic device (such as a cylinder), a hydraulic cylinder, a cam driven by a motor, etc. By controlling the driving device 5, an automated cutting action can be achieved, saving time and effort. The number of blanking holes 3 is set according to the number of lead pins 4 of the actual product 11 to be cut. One to multiple jacks can be set, and the position of the jack corresponds to the position of the lead pin 4 to be cut. As shown in the figure, in this embodiment, it is preferred to set the product placement position as a groove, the shape of the groove matches the relay, and the relay is placed in the groove to achieve the positioning of the lead pin 4.

[0030] The driving device 5 can be used to drive the first cutting plate 1 or the second cutting plate 2. The first cutting plate 1 and the second cutting plate 2 can displace the insertion hole and the blanking hole 3 by relative translation or by relative rotation.

[0031] In this embodiment, the lead pin 4 cutting device also includes an elastic reset member 6. The first cutting plate 1 is located between the driving device 5 and the elastic reset member 6. The driving device 5 is used to drive the first cutting plate 1 to rotate to cut off the lead pin 4. When the first cutting plate 1 rotates to perform the cutting operation, the elastic reset member 6 is squeezed. The elastic reset member 6 drives the first cutting plate 1 to rotate to the initial state where the plug hole is relative to the blanking hole 3 by rebounding. After the lead pin 4 of a product 11 is cut off, the elastic reset member 6 automatically rebounds to automatically reset the lead pin 4 cutting device, and then the lead pin 4 cutting operation of the next product 11 can be performed. The loading of the product 11 can be done manually or automatically by a robot. The lead pin 4 cutting device automatically cuts the lead pin 4 through the driving device 5 and automatically resets through the elastic reset member 6, which can realize the full automation of the lead pin 4 cutting operation, improve production efficiency, and reduce labor costs. In other embodiments, the first cutting plate 1 can also use other reset methods, such as manual rotation reset.

[0032] The elastic reset member 6 and the driving device 5 in this embodiment drive the first cutting plate 1 to rotate from opposite directions. The debris can be easily separated from the first cutting plate 1 as the first cutting plate 1 reciprocates. When the lead-out pin 4 is inserted into the socket, the debris stuck to the socket when the previous lead-out pin 4 is cut off can be cleaned.

[0033] The lead-out pin 4 cutting device also includes a base plate 7, a second cutting plate 2 and a driving device 5 are fixedly mounted on the base plate 7, a first cutting plate 1 is placed on the top surface of the second cutting plate 2, and the first cutting plate 1 rotates around a vertical rotating shaft 13, and the rotating shaft 13 is fixedly connected to the base plate 7 or the second cutting plate 2. In this embodiment, the first cutting plate 1 is arranged above the second cutting plate 2, and the cut waste falls from the blanking hole 3. A waste trough 8 is arranged below the blanking hole 3, and the waste cut by the lead-out pin 4 falls directly into the waste trough 8. In other embodiments, the first cutting plate 1 can also be arranged below the second cutting plate 2, or on one side of the second cutting plate 2 in the horizontal direction. Arranging the first cutting plate 1 above the second cutting plate 2 is conducive to the waste to quickly detach from the blanking hole 3 under the action of gravity, and avoid the waste from clogging the blanking hole 3. The waste trough 8 is arranged to facilitate the collection of waste. The blanking hole 3 is preferably a round hole, and the side wall of the round hole is smooth to avoid the waste from being stuck. Preferably, the aperture of the blanking hole 3 is larger than the aperture of the socket and the blanking hole 3 and the socket are coaxial. It is best that the aperture of the blanking hole 3 is larger than the length and width of the cut waste to avoid contact between the waste and the hole wall of the blanking hole 3. In this way, the waste cut off by the lead-out pin 4 can fall smoothly into the waste trough 8.

[0034] The lead-out pin 4 cutting device also includes a limiting structure, which includes a limiting column 9 and a limiting groove 10. The limiting column 9 is vertically arranged, and the limiting groove 10 is arranged on the first cutting plate 1. The limiting column 9 is fixed on the base plate 7 or the second cutting plate 2. The limiting column 9 is inserted into the limiting groove 10. When the first cutting plate 1 rotates around the rotating shaft 13, the limiting column 9 generates relative sliding in the limiting groove 10. The limiting groove 10 limits the moving path of the limiting column 9, thereby limiting the rotation angle of the first cutting plate 1. The limiting structure is intended to ensure that the first cutting plate 1 remains balanced and stable during the rotation process, and to limit the starting and ending angles of the rotation cutting.

[0035] The driving device 5 in this example is a cylinder, which is a standard part and has the advantages of easy material acquisition, simple operation, and a wide range of models to choose from. The telescopic rod of the cylinder is located on one side of the first cutting plate 1 in the horizontal direction and is spaced apart from the first cutting plate 1 to prevent the first cutter from interfering with the telescopic rod of the cylinder when the elastic reset member 6 rebounds to drive the first cutting plate 1 to reset and rotate.

[0036] A positioning column 12 is provided on the side of the first cutting plate 1 away from the driving device 5, and the positioning column 12 is fixed on the base plate 7. The two ends of the elastic reset member 6 push the positioning column 12 and the first cutting plate 1 respectively. The elastic reset member 6 includes but is not limited to a spring, a polymer elastic member, a metal spring, etc. The elastic reset member 6 in this embodiment is preferably a spring, and the positioning column 12 and the first cutting plate 1 are both provided with mounting holes at the positions corresponding to the ends of the spring, and the two ends of the spring are respectively fixed in the mounting holes on the positioning column 12 and the mounting holes on the first cutting plate 1.
