Description

Technical Field

[0001] The utility model belongs to the technical field of COF packaging, and particularly relates to a dust-proof device for a heat dissipation sticker machine. Background Art

[0002] In the existing technology, COF packaging is a chip soft film assembly technology that fixes the integrated circuit (IC) on a flexible circuit board (material strip), and the flexible circuit board is wound and stored on a material tray; in order to improve the heat dissipation performance of the IC on the material strip, it is necessary to place the material strip on a heat sink machine and affix several heat sinks to each IC.

[0003] When the heat sink machine is working, the rolled-up heat sink is unwound through the rotating material tray. There is a label film on the surface of the heat sink, which needs to be torn off. Then, each heat sink is attached to the corresponding IC in turn during transmission. The disadvantage is that after the heat sink is unwound, when the label film on the surface is torn off during the transmission of the heat sink, the impurity particles of the heat sink itself and the impurity particles generated by the friction between the heat sink and the guide roller fall onto the material strip product, causing the electrical performance of the IC chip to be affected. Utility Model Content

[0004] The utility model aims to provide a dust-proof device for a heat sink machine, which can prevent foreign particles of the heat sink itself and foreign particles generated by the friction between the heat sink and the guide roller from falling onto the material strip product, thereby preventing cross contamination and protecting the material strip product.

The shielding part and the inclined part of the shielding plate 1 block the impurity particles generated when the heat sink is unrolled, and the guiding part and the containing part of the shielding plate 2 block the impurity particles generated by the friction between the heat sink and the guide wheel, preventing the impurity particles from falling onto the material strip below.
