Cooling device for flexible circuit board processing

Abstract

This utility model proposes a cooling device for flexible circuit board processing, particularly relating to the field of flexible circuit board processing technology. It includes a cooling box. After the flexible circuit board is welded, it is placed on a tray. A fan is then activated to draw in external air through the inlet pipe, which is then transferred to the air chamber. The air passes through a filter and enters the outlet box, where it is blown out through the outlet channel, cooling the flexible circuit board. Some of the dust filtered by the filter falls into the collection box, which can be cleaned later by opening the cover. The operation is more convenient. During assembly, the anti-detachment pin is pulled upwards, disengaging one end of the pin from the slide groove and stretching the spring. The tray is then slid into the slide groove, abutting against one end of the inner cavity. The anti-detachment pin is then released, resetting and fixing its outer end to one end of the tray, thus securing the tray for positioning. For long-term use, the tray can be periodically disassembled and cleaned.
