Description

Technical Field

[0002] Pins usually refer to the external connection points of electronic components or integrated circuits, which are used to connect to circuit boards or other components. In integrated circuits, pins are usually metal feet that are inserted into solder holes on circuit boards to connect to other electronic components. The number and arrangement of pins depends on the type and function of the component. For example, the number of pins on an integrated circuit can range from a few to hundreds, while traditional components such as resistors and capacitors usually have only two pins. The numbering and arrangement of pins are usually defined by relevant standards and specifications, which helps ensure that components produced by different manufacturers can meet unified standards when connected and used. In electronic design and manufacturing, it is very important to correctly understand and use pins because it directly affects the connection and function of components. Light-emitting diodes are semiconductor devices used to emit light and need to be connected to electrical energy through pins.

[0003] However, the existing equipment has the following shortcomings: the existing LED pin bending processing equipment is usually operated by a manual bending machine. The manual bending machine is a device used for bending metal sheets, and the bending action is usually completed by an operating rod or a handle. This bending machine is usually used for small-batch production and simple bending tasks. The operation is relatively simple and suitable for some simple metal processing occasions. It requires the operator to complete the positioning and bending of the sheet through manual operation. It is usually used in metal processing workshops, repair plants and some small manufacturing industries, but it is poor in production efficiency and bending accuracy. Some automated bending machines are usually suitable for assembly line production, which is not conducive to use by small manufacturers.
