Abstract

The invention discloses a manual board discharging device for reflow soldering furnaces, which comprises a conveying chain (1) for conveying printed circuit boards, wherein the conveying chain meshes with a sprocket (3) transmitted by a transmission shaft (2). The device is characterized in that a one-way bearing (4) is sheathed outside the transmission shaft (2), a reflow soldering power unit (5) is arranged on one side of the one-way bearing, and the reflow soldering power unit transmits the one-way bearing by the chain to drive the transmission shaft. The device can discharge boards by manual operation during power failure without being affected by the force of the retarder of the power unit.

Description

technical field [0001] The invention belongs to an emergency treatment device in the case of an accidental power failure of a reflow soldering furnace, and in particular relates to a device for manually ejecting boards after a reflow soldering furnace is powered off. Background technique [0002] Surface mount technology (Surface Mount Technology, SMT) is to directly paste and solder chip components or micro components suitable for surface mounting to the specified position on the surface of printed boards or other substrates without drilling holes for printed boards. on the assembly technology. After applying this technology, the product is compact in structure, high in assembly density, small in size, and light in weight. When double-sided mounting is used, the assembly density reaches 5.5-20 pieces / cm2, which is more than 5 times the assembly density of plug-in components. The area of ​​the printed board can be saved by more than 60% to 70%, and the weight can be reduced...
