Background Art

[0002] Currently, domestic LED filament lamps are all assembled using traditional production lines. The installation and welding of the driving board of the LED filament lamp are manually operated by production workers, and the driving is welded and assembled using an electric soldering iron. The disadvantages of this processing method are as follows: First, the number of workers required remains high, resulting in high labor costs. Second, due to frequent handling operations, the glass bulbs of filament lamps have the poor characteristic of being fragile, leading to large losses during the processing process and increasing production costs. Third, the manual production method for welding and assembling the driving board of the LED filament lamp results in low production efficiency, poor product quality consistency, and low qualification rate. The automatic loading and welding machine for the LED filament lamp driving board is a new type of machine that realizes automatic welding and assembly of the driving board of the LED filament lamp.

[0009] Currently, the assembly of LED filament lamps is carried out manually on a traditional conveyor belt assembly line. Whether the assembly of LED filament lamps is carried out manually or by conveyor belt, it requires operators to assemble. This method has problems such as low efficiency, high cost, and many defective products. Especially, the lamp tube is a glass product and is fragile. An assembly worker can assemble 300 LED filament lamps in an 8-hour working day by manual assembly. Using this equipment, the LED filament lamp drive board can be automatically loaded into the welding machine, with a productivity of 1200 LED filament lamps per hour. Working 8 hours a day, it is 9600 LED filament lamps, and the efficiency is increased by 32 times. Brief Description of the Drawings
