Embodiment Construction

[0031] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0032] Such as Figure 1 to Figure 8 As shown, the present invention relates to a method for improving the welding efficiency of the COB board 1 and the quality of the finished product. In the step of welding the COB board 1 to the heat dissipation substrate 2, an annular heating module 3 is used to heat the outer surface of the COB board 1 from top to bottom. The ring side is heated.

[0033] In this way, the method for improving the welding efficiency of COB board 1 and the quality of finished products involved in the present invention adopts the method of annular heating, that is, the method of gradually heating from top to bottom from the outer ring to the inner ring, so that it can be directly heated To the heat dissipation substrate 2, thereby improving the heating efficiency and reducing the distance of...

Abstract

The invention discloses a method for improving the welding efficiency of a COB board and the quality of a finished product. In the step that the COB board is welded to a radiating substrate, an annular heating module heats the outer ring side of the COB board from up to down. Compared with the prior art, the heating efficiency is improved greatly, influence on welding performance of LED crystal grains on the COB board when the COB board is welded to the radiating substrate can be avoided, the production efficiency is improved, and the reject ratio finished lamps can be reduced.

Description

technical field [0001] The invention relates to the field of lamp manufacturing, in particular to a method for improving the welding efficiency of COB boards and the quality of finished products. Background technique [0002] Compared with distributed light sources, centralized light sources are currently being favored by many manufacturers due to their many advantages. For centralized light sources, it is obvious that the entire welding process will be divided into two independent welding processes. , The first welding process refers to welding the LED crystal grains on the COB board, and the second welding process refers to welding the COB board with LED grains on the heat dissipation substrate, so as to complete the molding of the entire lamp. [0003] In the manufacturing process of the above two independent welding processes, the current prior art usually has the following defects: [0004] 1. During the second welding process, since most of the heat dissipation substr...
