Description

Technical Field

[0001] The present invention relates to the technical field of chip access, and in particular to a packaged chip cover opening device. Background Art

[0002] Chips are precision electronic devices, encapsulating their circuits to ensure stable operation. Often, chip decapping (also known as opening the cover) is necessary for performance testing and failure analysis, as well as for performance analysis. There are two main methods for decapping: completely dissolving the chip package to expose the metal wiring; and removing only the plastic cover from the silicon core.

[0003] Among them, the second method is simpler and faster, but the second method usually uses a knife to manually remove the cover, which is inefficient and unsafe. The knife can easily scratch your fingers, and manual disassembly and assembly are required during use, which is inefficient and increases labor costs. Therefore, some auxiliary opening devices have appeared in the prior art to fix the chip, and then pry open the cover through an opening plate in a fixed position, which improves efficiency and safety. However, this opening device still requires manual operation. For this reason, the present invention proposes a packaged chip opening device to solve the above problems. Summary of the Invention

[0004] The object of the present invention is to provide a packaged chip cover opening device to solve the above-mentioned problems.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0015] Beneficial effects of the present invention:

[0016] (1) In the present invention, when opening the cover, after the cardboard of the packaged chip is fixed, the slider telescopic rod extends to contact the separation frame with the cardboard, and then the telescopic rod is translated to push the upper slider forward, thereby inserting the separation frame under the plastic cover of the packaged chip. The contraction of the telescopic rod drives the cover-opening gear meshed with it to rotate. At this time, the cover-opening gear can further drive the lifting shaft to rotate. When the lifting shaft rotates, the cover-opening frame can rotate along the lifting shaft. At this time, the angle between the cover-opening frame and the separation frame will slowly increase. When the angle becomes an obtuse angle, the plastic cover of the packaged chip is completely opened. At this time, the chip can be taken out, which solves the problem that the cover must be opened manually in the existing work;

[0017] (2) After the packaged chip is transported to the conveyor line, the positioning guide plate guides the packaged chip to the middle of the stop plate, and then the cover can be opened. After the cover is opened, the stop plate opens, and the shell of the packaged chip is transported to the trash can at the end. The chip is transferred to another conveyor line and transported to the subsequent production line, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

When opening the cover, the external fixing frame 4 is moved downward to press and fix the cardboard under the packaged chip, and then the plastic cover covering the chip is opened by the opening cover component 7. At this time, the suction cup 51 is extended downward by the material moving telescopic rod 5 to adsorb the chip, and the chip can be taken out and placed on the conveyor line 2 on the other side.
