Abstract

The invention discloses a circuit board introducing device of a solder-reflow furnace comprising a fixed guide rail (2) fixed to a furnace body brackets (1) at two ends. A conveying chain (3) is arranged in an extending section at the inner side of the fixed guide rail (2). The circuit board introducing device of the solder-reflow furnace is characterized in that an introducing block (4) is arranged at the front end of the conveying chain (3) at the entry of the solder-reflow furnace and provided with a horizontal guide block (41) approaching the upper end of the conveying chain (3). The device is applied to the front end of the conveying chain of the solder-reflow furnace, greatly improves the conveying stability of printed circuit boards and reduces the phenomena of dropping, clamping and climbing of the circuit boards.

Description

Technical field [0001] The invention belongs to the technical field of circuit board transportation design of a reflow soldering furnace, and in particular relates to a circuit board introduction device of a reflow soldering furnace that prevents board climbing and board drop. Background technique [0002] Surface mount technology has been widely adopted in recent years, and it is not difficult to find electronic products that use surface mount technology in daily life. Such as frequently used mobile phones, notebook computers, calculators, pagers, etc., can not leave the surface mount technology. The surface mount technology has advantages that the traditional plug-in technology can't compare: miniaturization: the volume of the traditional perforated component can no longer be reduced. Compared with perforated components, the volume of surface mount components is greatly reduced by many times, making electronic products more miniaturized. Large-scale, highly integrated electro...
