Embodiment Construction

[0016] refer to figure 1 , the filament tin spot method of the present invention comprises the following steps:

[0017] S1. Two or more filament strips are connected end-to-end through their electrodes, and a V-shaped structure is formed between adjacent filament strips connected together, and a tin structure to be lit is formed at the connection between the electrodes;

[0018] S2, maintaining the shape and structure between the filament strips;

[0019] S3. Tap the tin structure to be spot on the same horizontal plane in the tin pool at the same time, and wait for the tin on the tin structure to be spot to solidify;

[0020] S4. In the case that the tin structure to be spot is not stained with tin, repeat step S3 until all the tin structures to be spot are stained with tin and the tin is cooled and solidified, and the tin spot operation is completed.

[0021] Specifically, by connecting the electrodes of the two filament strips, each two filament strips form a sequentiall...

Abstract

The invention discloses a filament strip spot-tinning method. The filament strip spot-tinning method comprises the steps that electrodes of filament strips are connected so that to-be-spot-tinned structures can be formed at the connecting positions of the electrodes, then the to-be-spot-tinned structures on different horizontal planes are soaked in a tin bath for spot-welding processing, the spot-welding frequency can be effectively reduced, and accordingly the spot-welding efficiency is improved; and besides, a filament strip can have excellent consistency after being welded and fixed, so that the cost is effectively reduced and products are well produced advantageously.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a method for spotting tin on filament strips. Background technique [0002] LED filament lamps, with their 360-degree lighting angle and excellent brightness, are often used in various occasions. Multiple filament strips in LED filament lamps can be combined to present various shapes through welding, and the common ones are W-shape and V-shape. Existing filament strips are often fixed on the support of the stem by spot welding, or a thin metal wire is connected between the filament strip and the filament strip, and then spot welding is performed on the thin metal wire to connect two filament strip. This method needs to manually spot-weld the filament strips one by one, so it is easy to cause defects such as high cost and poor consistency, which is not conducive to the effective production of products. Contents of the invention [0003] In order to solve the above problems, the ob...
