The packaging frame 702 is adsorbed and transferred to the inside of the second box body 601 by the mechanical suction cup 102. The threaded rod 602 is driven to rotate by the output end of the servo motor 604, so that the two groups of second clamping pieces 605 are away from each other, and the inner walls of the two sides of the packaging frame 702 are abutted, so as to fix the packaging frame 702; S5, under the action of the output end of the second drive motor 616, the scraping knife 615 is driven to rotate, so that the scraping knife 615 can keep parallel state with each outer side wall of the packaging frame 702, and under the cooperation of the output end of the fifth stepper motor 608, the output end of the sixth stepper motor 612 and the output end of the sixth electric push rod 614, the scraping knife 615 can be sequentially attached to each outer side wall of the packaging frame 702 and scraped along each outer side wall, so as to realize the scraping of each outer side wall of the packaging frame 702, so that the surface becomes smooth, and the quality of the subsequent chip packaging product is improved; S6. At the same time as step S5 occurs, the output end of the second electric push rod 303 is contracted to drive the lower mold 307 to move to the left, and the output end of the first electric push rod 301 and the output end of the first drive motor 304 are used in coordination to realize the flipping of the lower mold 307, and then the output end of the first stepper motor 204 drives the first screw rod 202 to rotate, so that the upper mold 206 moves downward and passes through the square groove 101. At this time, the inner walls of the mold cavity formed by the upper mold 206 and the lower mold 307 for the packaging frame 702 are both facing downward, and then under the coordinated action of the output end of the second stepper motor 403 and the output end of the third electric push rod 405, the scraper 406 can scrape the inner walls of the mold cavity of the upper mold 206 and the lower mold 307 in turn, and completely remove the "bump" formed by the residual raw material, thereby ensuring the quality of the packaging frame 702 produced next time; S7. Then, the output end of the third stepper motor 508, the output end of the fourth stepper motor 510 and the output end of the fifth electric push rod 514 are used in coordination to make the glue injection head 515 reciprocate in the horizontal, vertical and vertical directions, injecting glue into the notch 701 cut out of the chip 7 with gold wire attached, and then the flattened packaging frame 702 is also transferred to the inside of the first box 501 through the mechanical suction cup 102, and the bottom of the packaging frame 702 is pressed into the notch 701 to achieve packaging. In this way, the contact area between the packaging frame 702 and the substrate on the chip 7 with gold wire attached is increased, and it is not easy to fall off, thereby further improving the packaging quality. Finally, the output end of the third stepper motor 508, the output end of the fourth stepper motor 510 and the output end of the fifth electric push rod 514 are used in coordination to make the glue scraper 517 clean up the excess glue that overflows, thereby ensuring the aesthetics of the packaged product.
