[0026] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0027] This invention provides an automated production device and method for flexible filament lamps. A clamping device coaxially and concentrically clamps the core column. The lamp strip is fed to the first conductive line of the core column by a feeding device perpendicular to the core column axis. The first electrode at one end of the flexible lamp strip is spot-welded to the first conductive line. A shaping device coaxial with the core column then shapes the flexible lamp strip by winding it around a groove into a predetermined shape. The second electrode of the flexible lamp strip is spot-welded to the second conductor, forming a closed loop. The lamp strip is then fixed by a support frame such as molybdenum wire winding, metal sheet slots, or glass slots on the core column. Finally, the shaping device detaches from the lamp strip and core column, completing the automated feeding, shaping, and spot-welding operations. The shaping device can adjust the groove according to the length, number of spiral turns, and shape of the flexible lamp strip to achieve one or more turns of lamp strip winding; it can also wind one or more lamp strips simultaneously, allowing for free selection of different lamp strip color temperatures to achieve dimming, color adjustment, or RGB dimming effects. Adjusting the shape of the device enables the shaping and spot welding of the molybdenum wire, metal sheet, and glass support frames. This method automates the production process of flexible light strips, including feeding, shaping, and spot welding, making it suitable for mass production. Attached Figure Description

[0038] The shaping device 2 has an expanding state and a contracting state to change the inner diameter of the cavity, so that the guide groove can contact or separate from the flexible light strip 8.

[0039] This embodiment also provides an automated production method for flexible filament lamps, using the automated production device described above, including the following steps:

[0040] 1) The clamping device 4 clamps the core post 3, so that the core post 3, the clamping device 4 and the shaping device 2 are in a coaxial position;

[0041] 2) The light strip support frame 5 is moved into the cavity;

[0042] 3) Place the shaping device 2 in the expanded state;

[0043] 4) The feeding device 1 conveys the flexible light strip 8 to the outside of the shaping device 2 and makes the first electrode of the flexible light strip 8 electrically connected to the first conductive wire 6;

[0044] 5) The feeding device 1 continues to convey the flexible light strip 8 into the guide groove; through the relative movement of the feeding device 1 and the shaping device 2, the flexible light strip 8 moves along the direction of the wire groove.

[0045] 6) Connect the other end of the flexible light strip 8 to the second conductive wire 7 electrically;

[0046] 7) Place the shaping device 2 in the retracted state;
