Description

TECHNICAL FIELD

[0001] The utility model relates to a packaging device, concretely relates to a packaging box of flexible circuit board. BACKGROUND

[0002] Flexible circuit board is made of polyimide or polyester film as base material and is a kind of highly reliable, excellent flexible printed circuit board, simply called soft board or FPC, with the characteristics of high wiring density, light weight and thin thickness. Due to the particularity of its material and structure, the flexible circuit board is packaged by suction packaging box to prevent device damage when punched and processed into a single piece. The existing packaging box of flexible circuit board is shown in Figure 1 and Figure 2 The packaging box includes a base plate 1, a recess 2 for placing a flexible circuit board is formed on the front surface of the base plate 1, and the bottom of the recess 2 is formed on the protrusion 3 protruding from the back surface of the base plate 1. Before delivery, the appearance of the flexible circuit board needs to be inspected. One side of the flexible circuit board can be inspected from the front surface of the base plate 1, but the other side of the flexible circuit board cannot be directly inspected because the suction packaging box is usually opaque. The current method is to invert the second packaging box on the back surface of the first packaging box (the packaging box is usually designed to be stackable, and the two packaging boxes can be automatically positioned when inverted and stacked), then lift the second packaging box, so that the flexible circuit board in the second packaging box is inverted on the protrusion 3 of the first packaging box, so that the other side of the flexible circuit board can be inspected. After inspection, the second packaging box is inverted on the first packaging box again, so that the flexible circuit board is reloaded into the recess 2 of the second packaging box. However, it is found in actual production that the flexible circuit board is easily out of position when inverted on the protrusion 3, which causes the flexible circuit board to not be reloaded into the recess 2 of the second packaging box after inspection, and the flexible circuit board needs to be adjusted one by one, which greatly affects the production efficiency.
