Abstract

The invention relates to the field of LED lamp production equipment, in particular to a winding device used for flexible LED filament production. The winding device comprises a fixing frame, a windingroller and a winding motor; a supporting frame is arranged on the lower surface of the fixing frame, a driving shaft is arranged in the fixing frame, the winding roller is arranged in the middle of the driving shaft in a sleeve mode,and the winding motor is fixedly connected to the outer side wall of the fixing frame; and a screw rod is further installed inside the fixing frame, a transmission shaft is arranged on the outer side wall of the fixing frame, a sliding block is arranged in the middle of the screw rod in a sleeve mode, a guide ring is fixedly connected to the upper surface of the sliding block, the side wall of the sliding block is fixedly connected to a fixing plate, a cleaning device is arranged on the fixing plate, and a moving mechanism is arranged inside the supporting frame. When winding operation is carried out by the winding device, a filament is wound around the winding roller, and meanwhile, the sliding block is driven to move left and right, so that the filamentis uniformly wound around the winding roller; and dust on the surface of the flexible LED filament is cleaned by utilizing a driving cleaning roller and a driven cleaning roller.

Description

technical field

[0001] The invention relates to the field of LED lamp production equipment, more specifically, a winding device for flexible LED filament production. Background technique

[0002] The substrate material of the flexible filament is made of extremely flexible polymer materials. The production process of flip-chip LED lamp beads has very high requirements on the heat resistance, light transmission and deformation resistance of the substrate. Medison tried more than a dozen materials, and finally found an ideal polymer material that could be used as a substrate. Printed circuits are made on polymer substrates, and flip-chip lamp beads are directly bound to the circuits to form HVLEDs in series. It is no longer necessary to use gold wire welding, the flexible LED filament can be bent at any angle to shape the filament, and the inside of the filament will not break, and the lamp will not die during use, which greatly improves the service life of the filament. The...
