Description
Technical Field
[0001] This invention relates to the field of chip packaging technology, and in particular to a chip packaging auxiliary welding device. Background Technology
[0002] A chip, also known as a microcircuit, microchip, or integrated circuit, refers to a silicon wafer containing integrated circuits. It is very small and often part of a computer or other electronic device. Before installation and use, chips need to be packaged for protection. Chip packaging technology is a process that encapsulates memory chips to prevent them from contacting the outside world and causing damage. Impurities and harmful gases in the air, even water vapor, can corrode the delicate circuitry on the chip, leading to a decline in electrical performance. Different packaging technologies vary greatly in manufacturing processes and procedures, and the packaging process plays a crucial role in ensuring the optimal performance of the memory chip.
[0003] Because of the small size of the chip, in order to facilitate chip packaging and soldering, the chip is fixed on the soldering station by a clamp, and then the soldering head of the soldering gun is fixed on a movable bracket. The soldering gun on the bracket is moved by the drive unit to package and solder the chip. However, when the drive unit starts the bracket to move, the bracket will shake, which will also cause the soldering gun to shake. This will cause the soldering position between the soldering gun and the chip to deviate, which can easily lead to missed soldering and affect the soldering effect of chip packaging.

[0016] 1. Compared with existing technologies, this chip packaging auxiliary welding device clamps the chip to be welded and packaged in a centering component on the top surface of a turntable. A drive unit drives a support plate to move longitudinally, moving the chip on the turntable below the welding torch. A first electric push rod pushes a base to move laterally, causing the chip on the turntable to move as well. This ensures the starting point of the chip welding joint is below the welding torch. Simultaneously, a first spring is compressed, then the first electric push rod returns to its original position, and the compressed first spring resets. When the first spring resets, it moves the base back to its original position. At the same time, the welding torch welds and packages the chip on the moving top surface of the base. By moving the chip to perform welding and packaging, the welding torch remains stationary, preventing the torch from shaking during welding and packaging. This prevents the welding point between the torch and the chip from shifting, thus avoiding incomplete soldering at the chip's weld joint.
[0017] 2. Compared with the existing technology, the chip packaging auxiliary welding device, the centering component and the pressure plate play a role in clamping and fixing the chip during the welding and packaging process, preventing the chip from shifting on the top surface of the turntable during the moving welding process.
[0018] 3. Compared with existing technologies, this chip packaging auxiliary welding device rotatably connects the turntable to the top surface of the base, which facilitates the welding and packaging of the chip on all four sides. It eliminates the need to remove the chip from the turntable, adjust its position, and re-clamp it, thereby saving time spent on readjusting the chip's position and improving the chip welding efficiency.

[0035] The chip to be soldered and packaged is clamped in the centering component on the top surface of the turntable 12. A drive unit drives the support plate 4 to move longitudinally, moving the chip on the turntable 12 below the soldering torch 28. The first electric push rod 6 pushes the base 5 to move laterally, causing the chip on the turntable 12 to move, so that the starting point of the chip soldering point is below the soldering torch 28. Simultaneously, the first spring 14 is compressed, then the first electric push rod 6 returns to its original position, and the compressed first spring 14 resets. When the first spring 14 resets, it moves the base 5 back to its original position. At the same time, the soldering torch 28 solders and packages the chip on the moving top surface of the base 5. By moving the chip, the soldering and packaging process is achieved, allowing the soldering torch 28 to... The 8 is stationary, preventing the soldering gun 28 from shaking during chip soldering and encapsulation. This prevents the soldering point between the soldering gun 28 and the chip from shifting, thus avoiding incomplete soldering. The centering component and pressure plate 10 clamp and fix the chip during soldering and encapsulation, preventing the chip from shifting on the top surface of the turntable 12 during moving soldering. The turntable 12 is rotatably connected to the top surface of the base 5, facilitating soldering and encapsulation of the chip on all four sides. There is no need to remove the chip from the turntable 12, adjust its position, and re-clamp it, thus saving time spent on readjusting the chip's position and improving the chip soldering efficiency.
[0036] Working principle: In use, the chip to be soldered is first clamped between four clamping blocks 22. These four clamping blocks 22, via a second spring 26 and a connecting rod 21, retract when the chip is clamped on the top surface of the turntable 12, thus holding the chip around its perimeter. This allows the turntable 12 to clamp chips of different sizes. Next, the second cylinder 11 drives the pressure plate 10 to descend, pressing it against the top surface of the chip to fix it. Then, the first drive motor 3 drives the screw to rotate, causing the guide block 16 to slide longitudinally within the guide groove 15. The guide block 16 causes the support plate 4 to move longitudinally on the top surface of the operating table 1. The support plate 4 then moves the base 5 towards the first pressure sensor 27, causing the chip... One side of the chip contacts the first pressure sensor 27. When the first pressure sensor 27 detects pressure, the first drive motor 3 stops. Then, the first electric push rod 6 drives the base 5 to move laterally. The base 5 drives the chip on the turntable 12 to move. At the same time, the first spring 14 in the first slide groove 18 is compressed, so that the chip on the top surface of the turntable 12 moves below the welding torch 28. Then, the second electric push rod 32 drives the support block 17 to move longitudinally. The support block 17 drives the welding torch 28 to move longitudinally, so that the center of the welding torch 28 is located at the starting point directly above the chip welding point. Then, the welding wire is laid on the chip welding point. Then, the first cylinder 8 drives the lifting block 9 to descend. The lifting block 9 drives the mounting block 31 to descend. The mounting block 31... The welding torch 28 is lowered, causing it to fit against the outer edge of the welding starting point. The second slider 34 outside the sleeve 29 slides within the second groove 33, causing the lifting block 9 to continue moving downwards until the second pressure sensor 35 on the top surface of the second slider 34 fits against the bottom surface of the third slider 36. This ensures that the end of the welding torch 28 is firmly attached to the welding wire. Simultaneously, the elastic force of the third spring 37 prevents excessive force from contacting the chip with the end of the welding torch 28, which could damage the chip. This improves the fit between the welding torch 28 and the welding wire without damaging the chip. Then, the first electric push rod 6 returns to its original position, and the compressed first spring 14 resets. When the first spring 14 resets, it drives the base 5 to return to its original position. At the same time, the welding torch 28 presses against the top surface of the moving base 5. During chip soldering and packaging, once one side of the chip is soldered, the first cylinder 8 raises the lifting block 9, causing the soldering gun 28 to rise. Then, the second cylinder 11 raises the pressure plate 10, separating it from the chip. Next, the first drive motor 3 drives the screw to rotate in the opposite direction, causing the guide block 16 to move in the opposite direction. The guide block 16 then moves the base 5 on the support plate 4 in the opposite direction, separating the chip on the top surface of the turntable 12 from the first pressure sensor 27. Then, the second drive motor 19 rotates the shaft, causing the turntable 12 to rotate, bringing the second soldering point on the chip below the soldering gun 28. Finally, the second cylinder 11 lowers the pressure plate 10, pressing it back onto the top surface of the chip.Then, the first drive motor 3 drives the turntable 12 to move in the direction of the first pressure sensor 27 via a screw, so that the second side of the chip is in contact with the first pressure sensor 27. Then, the first electric push rod 6 drives the base 5 to move laterally, and the base 5 drives the chip on the turntable 12 to move. At the same time, the first spring 14 in the first slide groove 18 is compressed, so that the chip on the top surface of the turntable 12 moves below the welding torch 28. Then, the second electric push rod 32 drives the support block 17 to move longitudinally, and the support block 17 drives the welding torch 28 to move longitudinally, so that the center of the welding torch 28 is located at the starting point directly above the chip welding point. Then, the welding wire is laid on the chip welding point. Then, the first cylinder 8 drives the lifting block 9 to descend, the lifting block 9 drives the mounting block 31 to descend, and the mounting block 31 drives the welding torch 28 to descend, so that the welding torch 28 is in contact with the outer edge of the welding starting point. The second slider 34 outside the sleeve 29 slides in the second slide groove 33, so that the lifting block 9 continues to move downward until the second pressure sensor 35 on the top surface of the second slider 34 and the third slider 36 are in contact. The bottom surfaces are aligned, ensuring a firm fit between the welding torch 28 and the welding wire. Then, the first electric push rod 6 returns to its original position, and the compressed first spring 14 resets. As the first spring 14 resets, it moves the base 5 back to its original position. Simultaneously, the welding torch 28 welds and encapsulates the chip on the top surface of the moving base 5. This process is repeated until all four welding points on the chip are welded. Then, the first cylinder 8 raises the lifting block 9, causing the welding torch 28 to rise. Next, the second cylinder 11 raises the pressure plate 10, separating it from the chip. Then, the first drive motor 3 drives the screw to rotate in the opposite direction. The screw drives the guide block 16 to move in the opposite direction, and the guide block 16 drives the base 5 on the support plate 4 to move in the opposite direction. This separates the chip on the top surface of the turntable 12 from the first pressure sensor 27. Next, the third cylinder 24 drives the push plate 23 to rise. The push plate 23 pushes the chip that has been soldered and packaged on the turntable 12 upwards, separating the chip from the four clamping blocks 22. This completes the unloading of the soldered and packaged chip, preventing the chip from getting stuck between the four clamping blocks 22 and making it difficult to remove.
