Manufacturing process of LED bulb with driver arranged inside

Abstract

The invention provides a manufacturing process of an LED bulb with a driver arranged inside. The manufacturing process is characterized in that the process comprises the assembling procedures of connection of a packaging column and a special driving power source, point butt-joint of a lamp filament, testing, sealing and exhausting, gluing, lamp base feeding, aging testing and packaging, and the driving power source is located in a bulb shell. The LED bulb comprises the driver and the shell, the driver is fixed in the shell which is composed of a shell cover and a packaging panel, identical packaging column mounting holes are formed in the center of the driver, the center of the shell cover and the center of the packaging panel correspondingly, and the packaging column mounting holes are in clearance fit with the packaging column; and two electrode wire holes are formed in the two sides of the packaging column mounting hole in the shell cover correspondingly, the packaging panel is an integrated circuit board, input electrode wires of the driver penetrate through the electrode wire holes, output conductor wires of the driver are connected with the packaging panel, and electrode branch wires are fixed to the upper end of the packaging panel. The assembling process of the LED bulb comprises the steps of connection of the driver and the packaging panel, shell cover installation, testing, and power source assembling. According to the manufacturing process, the mechanization degree is high, the labor intensity is low, product quality is high and stable, the cooling effect is good, and the service life is long.

Description

technical field [0001] The invention belongs to the manufacturing process of LED light bulbs, in particular to the manufacturing process of LED light bulbs with built-in drivers. Background technique [0002] The LED bulb is generally divided into two parts: the bulb shell 1 and the lamp base 2. At present, the production process of the LED bulb with the driver in the LED lamp base is: touch the filament 5 (the packaging column 11 is connected to the filament 5)—test—sealing exhaust (machine Operation, hereinafter referred to as machine)--testing-upper driver 3--welding-cutting wire-testing-upper heat-shrinkable tube 31-heating heat-shrinkable tube-glue-up lamp holder 2-test aging-package (machine), total Fourteen processes, the process is cumbersome, only the sealing and exhaust (machine) and the final packaging (machine) are machine-operated, and the rest are manual operations. At the same time, all processes after sealing and exhaust are completed with bulb shells, glass ...

[0002] The LED bulb is generally divided into two parts: the bulb shell 1 and the lamp base 2. At present, the production process of the LED bulb with the driver in the LED lamp base is: touch the filament 5 (the packaging column 11 is connected to the filament 5)—test—sealing exhaust (machine Operation, hereinafter referred to as machine)--testing-upper driver 3--welding-cutting wire-testing-upper heat-shrinkable tube 31-heating heat-shrinkable tube-glue-up lamp holder 2-test aging-package (machine), total Fourteen processes, the process is cumbersome, only the sealing and exhaust (machine) and the final packaging (machine) are machine-operated, and the rest are manual operations. At the same time, all processes after sealing and exhaust are completed with bulb shells, glass bulbs Fragile characteristics increase labor intensity, low work efficiency and high cost

For international standard E12-E17 bulbs, due to the narrow space in the lamp cap, the usual mechanical operation is changed to semi-manual operation, that is, manual assembly and mechanical clamping, which also become the bottleneck affecting the overall processing speed; the amount of glue used 1. The thickness of the coating is limited, which affects the bonding fastness; at the same time, the type of glue used is also affected. The use of ordinary glue needs to be cured at a high temperature of 300 degrees, which has a great impact on the life of the electronic devices in the driver in the lamp head. If you use The price of low-temperature glue is 10 times that of high-temperature glue. This is undoubtedly a fatal blow to LED bulbs, which are low-profit civilian products. Therefore, most companies use ordinary glue and control the curing temperature at 80-130 degrees (within Overcome the adverse effects of temperature on electronic devices), which also causes a decrease in bonding fastness, easy to fall off, and a comprehensive failure rate of 50%

[0003] As for the built-in LED bulb in the driver, only the applicant has completed the product design, and there is no mature production process to guide the production. There are also flaws in the original design structure, and the heat dissipation effect is not good, which affects the service life of the driver.
