Automatic production system for bulb lamps with LED (light-emitting diode) filaments and product detecting method of system

Abstract

The invention discloses an automatic production system for bulb lamps with LED (light-emitting diode) filaments. The system comprises a monitoring layer, a controlling layer and an equipment layer, wherein the equipment layer comprises intelligent spot welding equipment, intelligent sealing equipment, intelligent exhausting equipment and intelligent lamp-holder mounting equipment. The invention further discloses a product detecting method of the automatic production system for the bulb lamps with the LED filaments. The method comprises the following steps: step one, a spot welding detecting camera precisely performs location; step two, visual inspection is performed on spot welding positions, and substandard products are sorted out; step three, a visual system feeds back positions of core columns to a PLC (programmable logic controller) system; step four, automatic sorting of bad products is completed. The automatic production system for the bulb lamps with the LED filaments integrates the computer technology, the automatic control technology and the mechanical technology, and aims at improving the qualified rate of the bulb lamps with the LED filaments, achieving rapid and stable production, and improving the production efficiency of the bulb lamps with the LED filaments accordingly.

Description

Technical field [0001] The invention relates to an automatic production system for an LED filament bulb lamp, in particular to an automatic production system for an LED filament bulb lamp and a product detection method thereof. Background technique [0002] Due to the characteristics of the material, structure and manufacturing process of the LED filament bulb itself, the process is more complicated, and it is difficult to realize automatic production. The following problems have appeared: the irregular and soft shape of the guide wire is prone to deformation during feeding For drift, the shape correction of the upper and lower guide wires connected to both ends of the lamp post and the filament needs to be carried out. The angle and direction of the upper and lower guide wires need to be consistent; the structure of the wick on the lamp post is unique, and four different directions are required for welding. Lap the filament bar on the lamp post for welding. It is required that t...

Problems solved by technology

[0002] Due to the characteristics of the material, structure and manufacturing process of the LED filament bulb itself, the process is more complicated, and it is difficult to realize automatic production. The following problems have emerged: the shape of the guide wire is irregular and soft, and it is easy to deform when feeding For drifting, it is necessary to correct the shape of the upper and lower guide wires connected to the two ends of the filament on the lamp post, and the angle and direction of the upper and lower guide wires need to be consistent; the structure of the wick on the lamp post is relatively unique, and four different directions are required when welding Lap the filament strips on the lamp post for welding. It is required that the design of the welding station can realize the welding of the filament at different angles to ensure that the filament welding is accurate and in place; the lamp post is welded by the upper and lower parts, which cannot be guaranteed in shape The upper and lower parts of the lamp post are coaxial, so there will still be deviations in the filament after welding; in order to avoid the complexity of the equipment, it is necessary to reduce the equipment in the production system, which requires a set of equipment to complete multiple actions to meet the production process requirements At the same time, it is necessary to make the arrangement of the system equipment layer as compact as possible; each process equipment of the production system equipment layer adopts a cam mechanism. Cooperate with the transmission part to make the machine run smoothly, not only the speed of the equipment in each process is coordinated and orderly, but also the machine is required not to collide when a fault occurs; because the entire production system has many processes, product quality and production efficiency must be guaranteed at the same time , the control between each process must be coordinated to ensure the stable operation of the entire production system
