Production process of direct type backlight LED lamp strip

Abstract

The invention relates to a production process of a direct type backlight LED lamp strip. The production process comprises the process steps of automatic plate mounting, printing, piece pasting, on-line code-spurting, pre-furnace inspection, high-temperature reflow soldering, post-reflow inspection, adhesive dispensing, LENS sticking, low-temperature curing, pressure testing, light testing, opticaltesting, board separation and packaging. Common inspection conveyors and cooling inspection conveyors are arranged between all the process steps to replace a previous production mode which needs three small production lines, a complete production line is combined to achieve efficient and stable production of the direct type LED backlight lamp strip, and the production efficiency is improved greatly; and in addition, the process production line is further provided with a plurality of testing platforms for testing LEDs, the first yield of production is improved greatly, feeding is achieved at the front end, a finished product lamp strip with stable quality can be directly and efficiently produced at the rear end, the turnover time for up and down the line of the product is reduced, the labor cost is saved, material is prevented from being mixed, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a production process of a direct-down type backlight LED lamp bar. Background technique [0002] Direct-type backlight strips are mainly used in the backlight module of TVs or display screens. In addition, various advertising light boxes and similar display internal light sources will also use direct-type backlight strips. [0003] At present, the production process of producing backlight strips on the market, such as figure 1 As shown, currently mainly rely on multiple production lines ( figure 1 L1 line body, L2 line body, L3 line body three production lines) processing and combined production, such a production line generally requires 14 to 17 people, the labor cost is high, and, because of the need to transfer semi-finished products in these three production lines, therefore, need Many times of workers' handling and turnover, due to factors that are considered to be easy to cause mixing, causing serious losses to the fact...
