Abstract

Disclosed is a computer main board production line. The computer main board production line comprises a screen printing machine, a chip mounter and a backflow furnace; the screen printing machine is connected with the chip mounter through a first transport band; the chip mounter is connected with the backflow furnace through a second transport band; a first optical automatic detector and a first screening mechanism are mounted above the first transport band; the first optical automatic detector is positioned on the upper reach of the first transport band and the first screening mechanism is positioned on the lower reach of the first transport band; a second optical automatic detector and a second screening mechanism are mounted above the second transport band; the second optical automatic detector is positioned on the upper reach of the second transport band and the second screening mechanism is positioned on the lower reach of the second transport band; and the output ends of the first and second screening mechanisms are positioned above the first and second transport bands respectively. By virtue of the computer main board production line, working procedures of production, detection and poor product elimination of the computer main board can be completed in a full automatic manner, production cost is lowered and production quality is improved.

Description

technical field [0001] The invention relates to the technical field of computer production, in particular to a production line for computer motherboards. Background technique [0002] At present, the production process of computer motherboards is generally divided into the following three steps: 1. Silk screen printing, printing solder paste on the pad of CPB to prepare for component placement; 2. SMT patch, on the PCB board, through the patch 3. Reflow, the reflow furnace has 8 temperature zones to melt the solder paste from paste to liquid and then to solid. These three processes are independent of each other. After completing a project, enter the next project. Before and after each process, an AOI (Automatic Inspection Instrument) test is required. Only those who pass the test can enter the next process. If they are not qualified need to be removed. [0003] Based on the above workflow, most of the production lines are independent of each other, and cannot realize the t...
