Problems solved by technology

However, because the LED filament in the finished wick has a certain angle with the axial direction of the stem, and at the same time, there is also a certain angle between the LED filaments in the wick, so the existing technology only welds one filament at a time.

Abstract

The invention discloses an LED filament point welding double-filament feeding device which comprises a filament positioning mechanism and a filament feeding mechanism for sucking filaments from the filament positioning mechanism and sending the filaments to a welding position. The filament positioning mechanism comprises two rotatable positioning dies. The upper surfaces of the two positioning dies can be each horizontally and fixedly provided with one filament. After the two positioning dies are rotated to be at the set angle, the angle between the two filaments on the two positioning dies is equal to the angle of the filaments at the corresponding positions in a produced lampwick. The filament feeding mechanism comprises two suckers for sucking the filaments. The bottom faces of the two suckers are provided with filament grooves matched with the filaments respectively. The angle between the two filament grooves is equal to the angle of the filaments at the corresponding positions in the produced lampwick.

Description

technical field [0001] The invention relates to the technical field of production equipment of lighting equipment, in particular to a dual-filament feeding device for LED filament spot welding. Background technique [0002] At present, the application of LED filament in the field of lighting equipment is generally to make it into an LED bulb, and its wick is made by welding the LED filament to the stem. Before welding, the LED filament needs to be positioned in the welding spot on the stem. However, because the LED filament in the finished wick has a certain angle with the axial direction of the stem, and at the same time, the LED filaments in the wick also have a certain angle, so the existing technology only welds one filament at a time. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a dual-filament feeding device for LED filament spot welding that can position and feed two filaments at a time. [0004]...
