What Are the Process Application Characteristics of LED Light Plate Laser Welding Machine
LED lamp is an electroluminescent semiconductor material chip, which can directly convert electricity into light. Use silver glue or white glue to cure it on the support, then connect the chip and circuit board with silver wire or gold wire, seal it with epoxy resin around to protect the internal core wire, and finally install the shell, so the seismic performance of LED lamp is good.
The structure of existing LED lamps is usually that the substrate loaded with LED semiconductor chip is vertically contained in the lamp tube. The semiconductor chip is composed of two parts. One part is p-type semiconductor, in which holes are dominant, and the other end is n-type semiconductor, mainly electrons. But when the two semiconductors are connected, a p-n junction is formed between them. When the current acts on the chip through the wire, the electrons will be pushed to the p region, where the electrons and holes compound, and then emit energy in the form of photons. This is the principle of LED light emission. The wavelength of light, that is, the color of light, is determined by the material forming the p-n junction.
characteristic:1. Energy saving: the energy consumption of white LED is only 1 / 10 of that of incandescent lamp and 1 / 4 of that of energy-saving lamp.2. Longevity: the service life can reach more than 100000 hours, which can be described as "once and for all" for ordinary family lighting.
3. It can work at high speed: if the energy-saving lamp is started or turned off frequently, the filament will turn black and break down quickly, so it is safer.4. Solid state package, belonging to the type of cold light source. Therefore, it is easy to transport and install, and can be installed in any micro and closed equipment, not afraid of vibration.5. LED technology is progressing with each passing day. Its luminous efficiency is making an amazing breakthrough, and the price is also decreasing. An era of white LED entering the family is coming rapidly.
6. Environmental protection, no harmful substances of mercury. The assembly parts of LED bulbs can be easily disassembled and assembled. They can be recycled by others without being recycled by the manufacturer.Solder manufacturing process of LED lamps:
Because the semiconductor chip main control circuit board in the LED lamp is flake, and the annular base strip is circular, it is difficult to locate when welding the main control circuit board and the annular base strip, and there is no corresponding automatic welding equipment. At present, it is manual welding, the labor efficiency is low, and the work efficiency cannot be improved, Even if some special automatic welding equipment can complete solder treatment, the equipment production cost is very high. Therefore, Shenzhen Zichen laser equipment Co., Ltd. has improved the welding process of this product to enable it to realize the purpose of automatic welding after manual loading.
The laser automatic soldering machine for LED light plate includes a laser automatic soldering system, a 4-station rotating workbench, and several fixed fixtures for placing the LED light plate to be soldered. The welding process has the functions of CCD intelligent positioning, digital temperature control, pre welding tin spot welding and post welding detection. Nowadays, the laser soldering machine produced by Zichen is widely used in the automatic welding of LED lamp industry.fqj
