Description

Technical Field

[0002] An IC chip (Integrated Circuit Chip) is an integrated circuit formed by placing a large number of microelectronic components (transistors, resistors, capacitors, etc.) on a plastic substrate to form a chip. These components are interconnected through complex circuits to form a microelectronic system with specific functions. IC chips include wafer chips and packaged chips. The corresponding IC chip production line consists of two parts: wafer production line and packaging production line. IC chips are an indispensable component of modern electronic equipment. They are widely used in various fields such as computers, communication equipment, consumer electronics, automotive electronics, industrial control systems, etc.

[0003] The feeding, testing, chip direction adjustment and packaging of traditional devices often require manual assistance, such as manually placing chips into packaging bags and manually adjusting the chip direction to match packaging requirements. This is not only inefficient, but also prone to unstable packaging quality due to human operational errors. In addition, the equipment for feeding, testing, packaging and other links is scattered, and there is a lack of a coherent automated coordination mechanism, resulting in a slow production cycle and difficulty in adapting to the efficient needs of chip mass production. At the same time, the appearance of the chip needs to be inspected before entering the package. Traditional devices can only perform single-sided inspection. If the other side needs to be inspected, the chip needs to be turned over and re-sent to the inspection device, which prolongs the entire inspection process and affects production efficiency. In response to the above problems, a chip packaging device for an automatic chip transfer machine is proposed to solve them. Summary of the Invention

[0031] The electrical components, pneumatic components and control logic in this article are all controlled by an external main controller, and the main controller can be a conventional known device such as a computer. The specific implementation method of this disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0032] Working principle: The chips to be packaged are fed into the first conveyor belt 607 of the flip assembly 6 by an external transfer machine to ensure that the chips are transported in a straight line. When the chips are transported to the rear end of the first conveyor belt 607 and are located at the first notch 602, the second detection CCD10 performs an appearance inspection on the chips (such as whether they are damaged or whether the pins are intact). The inspection data is transmitted to the control system. If the chip is unqualified, the control system starts the first cylinder 605 on the first support 604, and its output end pushes the first push plate 606 to push the unqualified chip from the first notch 602 to the second conveyor belt 608 at the second notch 603. Then the second conveyor belt 608 works to transport the unqualified chips to the waste area; the qualified chips are continued to be transported to the left by the first cylinder 605. Qualified chips enter the storage slot 614 inside the rotating column 612. The second cylinder 618 on the second support 617 is activated, and the output end pushes the fixed base 611 to move along the length of the movable guide rail 610. (The height of the storage slot 614 matches the chip to ensure that the chip does not shake when flipping inside the storage slot 614.) The rotating column 612 in the fixed base 611 moves with it. Because the toothed ring 613 on the outer surface of the rotating column 612 engages with the rack 609, the toothed ring 613 drives the rotating column 612 to rotate 180 degrees during the movement, achieving chip orientation flipping (for example, adjusting the chip pin orientation to meet packaging requirements). The guide base 619 limits the piston rod of the second cylinder 618 to ensure a stable movement trajectory.The limiting push rod 616 prevents the rotating column 612 from rotating excessively. The flipped chip moves with the rotating column 612 to the right side of the third conveyor belt 701. The third cylinder 622 on the third support 621 is started, and the output end pushes the second push plate 623 to push the chip from the storage slot 614 to the third conveyor belt 701. The first detection CCD9 performs a secondary inspection on the flipped chip (to confirm whether the direction is correct, whether it is damaged, and whether the pins are intact). If the chip is unqualified, the control system starts the fourth cylinder 706 on the support seat 705, and its output end pushes the push block 707 to push the unqualified chip out of the discharge notch 703 of the rear baffle 702 and pushes it out through the first guide plate 70 4 is collected into the waste area, and the qualified chips are conveyed to the left along the third conveyor belt 701 to the waiting packaging area of ​​the packaging component 8. The transfer robot arm 5 grabs the anti-static shielding bag 11 from the storage box 4 (the transfer robot arm 5 clamps the upper middle part of the anti-static shielding bag 11), and transfers the shielding bag to the pneumatic clamping jaws 807 of the packaging component 8 according to the preset trajectory, waiting to be opened. The pneumatic clamping jaws 807 work so that the two pneumatic clamping fingers move relative to each other, so that the clamping plate 811 clamps the front and back sides of the anti-static shielding bag 11. After clamping is completed, the transfer robot arm 5 resets and prepares to transfer the next anti-static shielding bag 11, and the fifth cylinder 809 on the fixing bar 808 starts The output end pushes the suction cup 810 to move rightward to adsorb the left surface of the anti-static shielding bag 11, and then the servo motor 805 is started to drive the bidirectional screw 803 on the mounting frame 802 to rotate. Since the front and rear threads of the bidirectional screw 803 are in opposite directions, the two moving blocks 806 on its outer surface move toward each other along the guide rod 804, driving the pneumatic clamping claws 807 to move toward each other synchronously, applying an inward squeezing force to the anti-static shielding bag 11. At the same time, the output end of the fifth cylinder 809 pulls the suction cup 810, thereby applying an outward pulling force to the left side of the anti-static shielding bag 11, thereby opening the bag mouth of the anti-static shielding bag 11, and the third conveyor belt 701 will close The chips are transported to the far left, where they pass through the second guide plate 708 and fall into the anti-static shielding bag 11. After the chips are bagged, the servo motor 805 reverses, driving the moving block 806 and pneumatic gripper 807 to move in the opposite direction, making the bag opening of the anti-static shielding bag 11 relatively closed (although it cannot be completely sealed, the gap left to prevent the chips from falling during the transfer process). The chip bag is released by the pneumatic gripper 807, and the suction cup 810 loses its suction force. Under the action of gravity, the chip falls into the discharge chute 3 on the left side of the packaging table 1 and slides out along the curved chute, completing the entire packaging process. The chip is then sealed with the external heat sealing device, and all components are reset to enter the next packaging cycle.
