Description

Technical Field

[0001] The utility model relates to the technical field of electronic component processing, in particular to a SMT component pin shearing and positioning device. Background Art

[0002] Electronic components are components of electronic components and small machines and instruments. To facilitate the installation of various components, electronic components generally have longer pins. In the process of circuit board production, welding is inevitable. Some components are specially designed with multiple pins to better position and fix on the circuit board, but in order to facilitate welding, the pins of electronic components need to be sheared.

[0003] After searching, the patent document with publication number: CN219817854U discloses a device for shearing and positioning the pins of electronic components, including a processing base plate, the upper surface of which is fixedly connected with a positioning box and a cutting box, the inner bottom wall of the positioning box is fixedly connected with a motor, the output end of the motor is fixedly connected with a main gear, the inner wall of the positioning box is fixedly inlaid with two bearings, the inner rings of the two bearings are fixedly connected with a bidirectional threaded rod, and the outer surface of the bidirectional threaded rod is threadedly connected with two screw plates. Through the coordinated use of the bidirectional threaded rod, the screw plate, the guide rail, the sliding block, the clamping plate, the straight long rod and the placement concave table, the device can make the rotation of the bidirectional threaded rod drive the two screw plates to move closer to each other, so that the two clamping plates move closer to each other to clamp and fix the component body, prevent the component body from being offset during shearing, improve the efficiency of shearing the pins, and have the advantages of more convenient and time-saving and labor-saving operation for fixing the component body.

[0004] When the above device is in use, two clamping plates are required to fix the component body, and then the electric push rod is used to adjust the position of the square plate, the connecting plate and the shearing mechanism, so as to achieve the effect of shearing the pins of the component body. Since the electronic components need to be placed individually in the placement recess and sheared in turn; it is impossible to cut multiple pins and adjust the cutting length, and it cannot be used for different electronic components. In addition, the subsequent bending of the pins requires additional equipment to operate, which is time-consuming and labor-intensive. Therefore, we propose an SMT component pin shearing and positioning device to solve the above problems. Utility Model Content
