Description

Technical Field

[0001] The present invention relates to the technical field of microwave chip welding, and more specifically to a microwave chip packaging device welding device and method. Background Art

[0002] Reflow soldering is mainly used in surface mount technology. It is achieved by heating the microwave chip packaging device pre-placed on the circuit board to melt the solder paste, and then cooling and solidifying it. In the welding of microwave chip packaging devices, the reflow soldering furnace achieves welding by precisely controlling the temperature of the welding area. It usually has multiple temperature zones, each of which can independently set the temperature and heating time. When working, the circuit board enters from one end of the furnace and passes through the preheating zone, reflow zone and cooling zone along the conveyor track. In the preheating zone, the temperature gradually increases to evaporate the solvent in the solder paste and reduce splashing and voids in the subsequent welding process. In the reflow zone, the temperature reaches above the melting point of the solder alloy, so that the solder melts and forms a good connection between the component pins and the circuit board pads. The cooling zone solidifies the molten solder to complete the welding process.

[0003] In the welding of microwave chip packaging devices, the circuit board is usually placed directly on a conveyor belt and transported to a reflow oven for heating. During the transmission process, the circuit board may be affected by the vibration of the transmission equipment itself and shift in position, which may cause the position of the circuit board in each temperature zone in the reflow oven to be inconsistent, resulting in uneven heating of the circuit board and affecting the quality of the welding point; on the other hand, after the conveyor belt continues to work, it is affected by the high temperature of the reflow oven and its own temperature will gradually increase, which may cause the temperature at the bottom of the circuit board to be inconsistent with the top, causing the solder to melt unevenly, thus affecting the quality of the welding point.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention designs a carrier frame with lifting and clamping functions, so that when the circuit board body follows the carrier frame into the reflow soldering furnace body for soldering, the circuit board body can be clamped and fixed by the clamping assembly of the carrier frame, ensuring that the position of the circuit board body inside the reflow soldering furnace body is relatively stable, avoiding position displacement of the circuit board body and causing uneven heating, which affects the quality of the soldering points. At the same time, the circuit board body can be lifted by the carrier frame to above the conveyor belt inside the reflow soldering furnace body, so that the circuit board body is away from the conveyor belt, avoiding the circuit board body being easily affected by the conveyor belt and causing the temperature at the bottom of the circuit board body to be inconsistent with the top, causing uneven melting of the solder, thereby affecting the quality of the soldering points. At the same time, the circuit board body above the conveyor belt can ensure that it is heated evenly at all angles, thereby improving the soldering quality.

[0016] 2. In the present invention, when gear one rotates forward, gear one drives the rotating rod to rotate, and the rotating rod drives the worm wheel to rotate through the worm, and the worm wheel drives the rotating drum to rotate in the supporting drum, and the arc groove of the rotating drum drives the sliding column to move upward, and further drives the lifting column to slide upward along the sliding protrusion of the supporting drum, thereby driving the lifting and positioning frame one to rise, so that the circuit board body on the top of the device placement plate rises, and the circuit board body moves away from the conveyor belt and enters the space above the conveyor belt. Since it is difficult for the worm wheel to drive the worm to rotate, the lifting column can maintain a stable state after rising, and it is difficult to rely on its own gravity to cause a situation of falling, thereby realizing the function of locking the state after rising, and further enabling the circuit board body after rising to maintain a relatively stable state, thereby improving the stability of welding.

[0017] 3. The present invention also arranges an outer rack 1 and an inner rack 1 on the top surface of the forward guide plate in a staggered manner, and arranges an outer rack 2 and an inner rack 2 on the bottom surface of the reverse guide plate in a staggered manner, and the rotation directions of the gear 2 and the gear 1 are staggered, so that after the device carrier enters the main body of the reflow soldering furnace, the gear 1 of the front rack and the gear 2 of the rear rack can be meshed and connected with the outer rack 1 and the inner rack 1 on the top surface of the forward guide plate respectively at the same time, and the outer rack 1 drives the gear 1 to rotate forwardly, and the inner rack 1 drives the gear 2 to rotate forwardly, so that the lifting and positioning frame 1 and the lifting and positioning frame 2 can rise at the same time, and the device is placed on the top of the electrical board. The main body of the circuit board is driven to rise and move away from the conveyor belt. After the welding operation is completed, the conveyor belt transports the device carrier to the output end of the reflow oven main body, so that the gear 1 of the front rack and the gear 2 of the rear rack are respectively meshed with the outer rack 2 and the inner rack 2 on the bottom surface of the reverse guide plate. The outer rack 2 drives the gear 1 to rotate in the opposite direction, and the inner rack 2 drives the gear 2 to rotate in the opposite direction, so that the lifting and positioning frame 1 and the lifting and positioning frame 2 can be lowered at the same time, and the carrier can automatically lift the circuit board main body in the process of being transported forward inside the reflow oven main body, making the entire welding process more convenient.

[0018] 4. The present invention designs a clamping assembly, and during the process of the lifting and positioning frame one and the lifting and positioning frame two rising, the plug plate can be gradually left from the slot, so that the bottom surface of the clamping plate loses the supporting effect of the plug plate, and the slide cylinder is subjected to the elastic force of the arc spring, so that the slide cylinder slides along the arc column, and further drives the clamping plate to rotate through the connecting rod, so that the clamping plate is gradually pressed down on the top surface of the circuit board body, and a clamping effect is formed on the four corners of the top surface of the circuit board body through the four clamping plates. When the lifting and positioning frame one and the lifting and positioning frame two are lowered, the plug plate can be gradually inserted into the slot, and the rotating cylinder on the top of the plug plate pushes the clamping plate to rotate and open, so that the four clamping plates lose the clamping effect on the circuit board body, which not only realizes the linkage function with the lifting and positioning frame one and the lifting and positioning frame two, but also enables the clamping assembly to automatically clamp or release, provides convenience for the welding process, and can ensure the stability and reliability of welding through the clamping effect formed at the four corners of the top surface of the circuit board body.

[0019] 5. The present invention positions the four corners of the circuit board body through two groups of mutually symmetrical device placement plates, so that the circuit board body can remain stable on the top surface of the device placement plate and is not prone to shaking or position displacement. In addition, by setting the side wall of the device placement plate as a curved plate-like structure, during the unloading process, when the device placement plate rotates with the conveyor belt, it can be separated from the circuit board body through the curved plate-like structure without scratching the circuit board body, thereby protecting the circuit board body.

When descending, the plug plate 66 can be gradually inserted into the slot 6402, and the rotating cylinder 6601 on the top of the plug plate 66 pushes the clamping plate 6501 to rotate and open, so that the four clamping plates 6501 lose the clamping effect on the circuit board body 8, which not only realizes the linkage function with the lifting and positioning frame 1 64 and the lifting and positioning frame 2 71, but also enables the clamping assembly 65 to automatically clamp or release, providing convenience for the welding process, and can ensure the stability and reliability of welding through the clamping effect formed at the four corners of the top surface of the circuit board body 8.

Similarly, the inner rack 1 4102 drives the lifting and positioning frame 2 71 to rise simultaneously with the lifting and positioning frame 1 64 through the gear 2 7201, so that the circuit board body 8 on the top of the device placement plate 6401 rises, and the circuit board body 8 moves away from the conveyor belt 3 and enters the space above the conveyor belt 3. The circuit board body 8 is heated by the reflow oven body 1 to melt the solder paste on the circuit board body 8. Under the action of surface tension, the solder will wrap the solder joint position of the microwave chip packaging device and the circuit board body 8. Finally, in the cooling zone of the reflow oven body 1, the solder is quickly cooled and solidified to complete the welding process.

[0051] S3, clamping operation, during the rising operation, as the lifting and positioning frame 1 64 and the lifting and positioning frame 2 71 rise, the plug plate 66 will gradually leave the slot 6402, so that the bottom surface of the clamping plate 6501 loses the support of the plug plate 66, and the slide cylinder 6503 is subjected to the elastic force of the arc spring 6505, so that the slide cylinder 6503 slides along the arc column 6502, and further drives the clamping plate 6501 to rotate through the connecting rod 6504, so that the clamping plate 6501 is gradually pressed down on the top surface of the circuit board body 8, and the four clamping plates 6501 form a clamping effect on the four corners of the top surface of the circuit board body 8;

[0052] S4, unloading operation, after completing the welding operation, the conveyor belt 3 conveys the device carrier 5 to the output end of the reflow oven main body 1, so that the gear 1 6302 of the front rack 6 and the gear 2 7201 of the rear rack 7 are respectively meshed and connected with the outer rack 2 4201 and the inner rack 2 4202 on the bottom surface of the reverse guide plate 42 at the same time. As the device carrier 5 continues to move forward, the outer rack 2 4201 drives the gear 1 6302 to rotate in the opposite direction, and the reversely rotating gear 1 6302 causes the lifting and positioning frame 1 64 to descend. Similarly, the inner rack 2 4202 simultaneously drives the gear 2 7201 to rotate in the opposite direction, so that the lifting and positioning frame 2 71 follows the lifting and positioning frame 1 64 to descend at the same time, further making the plug plate 66 gradually inserted into the slot 6402, and the rotating cylinder 6601 on the top of the plug plate 66 pushes the clamping plate 6501 to rotate and open, so that the four clamping plates 6501 lose the clamping effect on the circuit board main body 8, and finally the circuit board main body 8 can be removed at the output end of the reflow oven main body 1.
