Description

Technical Field

[0001] The utility model relates to the technical field of light emitting diode welding, in particular to a light emitting diode welding device with a positioning function. Background Art

[0002] LED is a diode made of a compound of gallium (Ga), arsenic (AS) and phosphorus (P). When electrons and holes recombine, they can radiate visible light. Therefore, they can be used to make light-emitting diodes, which are used as indicator lights in circuits and instruments, or to form text or digital displays. It is a type of semiconductor diode that can convert electrical energy into light energy. It is often abbreviated as LED. As a conductive element, LED is widely used in various PCB circuits.

[0003] The existing soldering of LED light-emitting diodes requires inserting the lead frame of the light-emitting diode into the pin through-hole on the light-emitting diode soldering station on the PCB board before soldering. When soldering manually, only one can be soldered one by one, which is inefficient. When soldering in batches by machine, the positions of the light-emitting diodes on different circuit boards are different, making machine positioning difficult. Therefore, we propose a light-emitting diode soldering device with a positioning function. Utility Model Content
