Description

Technical Field

[0001] The invention relates to the technical field of welding processing, and in particular to a component welding device for producing photovoltaic micro-inverters. Background Art

[0002] Photovoltaic micro-inverter, whose full name is micro photovoltaic grid-connected inverter, is a device that converts direct current from a single solar cell module into alternating current. During the production process of photovoltaic micro-inverter, multiple components need to be soldered on the constructed PCB board, and the components also include pin components.

[0003] Conventionally, the soldering of pin components is usually performed by a wave soldering process. First, the pin components are mounted on a PCB. Then, the PCB is sprayed with flux and preheated. The preheated PCB enters the soldering area. The molten liquid solder forms a solder wave of a specific shape under the action of a pump. When the PCB passes through the solder wave crest at a certain immersion depth and angle, the solder contacts the pad and the solder foot and completes the soldering. However, in the conventional soldering device, the angle between the PCB and the solder wave crest is not conveniently adjusted during the soldering debugging preparation stage. Summary of the invention

[0012] As a further technical solution of the present invention, the driving member includes a screw rod rotatably arranged between two connecting seats, the screw rod thread passes through the translation block, and a motor 2 for cooperating with the screw rod rotation is fixed on the side wall of one of the connecting seats, and two guide columns 2 are symmetrically fixed between the two connecting seats, and each guide column 2 can movably pass through the translation block.

[0013] As a further technical solution of the present invention, two connecting blocks 1 are fixed on both sides of the dual-axis cylinder, and two guide rods 1 are symmetrically fixed on one side of the clamp close to the connecting block 1, and each guide rod 1 is movable and penetrates into the corresponding connecting block 1.

[0014] As a further technical solution of the present invention, a pressure plate is movably provided below the double-axis cylinder for lifting and lowering, and a plurality of pressing protrusions are fixed on the lower end surface of the pressure plate. Connecting blocks 2 are fixed on both sides of the double-axis cylinder, and two guide rods 2 are detachably provided on the upper end surface of the pressure plate. Each guide rod 2 movably passes through the connecting block 2, and a limiting block is fixed on the upper end of each guide rod 2.

[0018] Beneficial effects of the present invention:

[0019] 1. When in use, the PCB board with components plugged in is transported by the electric feeding conveyor frame. When the PCB board is about to approach the tin melting furnace, the electric feeding conveyor frame stops conveying the PCB board, and then the rotating frame moves downward with the double-axis cylinder, the connecting rod and the clamping claw under the action of the lifting unit until the PCB board is located between the two clamping claws, and then the telescopic end of the double-axis cylinder contracts, prompting the two clamping claws to clamp the PCB board, and then under the action of the translation unit, the rotating frame is prompted to move away from the electric feeding conveyor frame with the double-axis cylinder, the clamping claw and the PCB board, and then the rotating unit drives the rotating frame with the double-axis cylinder, the clamping claw and the PCB board to a certain angle as needed, and then under the action of the translation unit and the lifting unit, the welding surface of the PCB board is prompted to move toward the solder wave crest of the tin melting furnace, which is easy to use. After the PCB board passes through the tin melting furnace, the rotating unit prompts the PCB board to rotate to a horizontal state, and then with the cooperation of the lifting unit and the translation unit, the PCB board is placed on the electric unloading conveyor frame, and the PCB board is sent out of the processing warehouse by the electric unloading conveyor frame.

[0020] 2. When the electric feeding conveyor conveys the PCB board to a position close to the tin melting furnace, the double-axis cylinder moves downward with the clamping claws to prepare to clamp the PCB board. During this process, the pressure plate moves downward with the double-axis cylinder until the pressing protrusion on the lower end surface of the pressure plate contacts the upper end surface of the pin component. During this process, the spring is squeezed and contracted, exerting a downward force on the pressure plate, the pressing protrusion and the pin component. On the one hand, it avoids the welding part of the pin component in an inclined state from shaking and deviating when it contacts the solder, affecting the welding quality. On the other hand, it avoids shaking and deviating when the PCB board is adjusted with the pin component for angle adjustment, affecting the welding accuracy.

[0021] 3. After the PCB board is welded, the dual-axis cylinder and the clamp cooperate with the rotating unit, the lifting unit and the translation unit to transport the PCB board to the electric discharge conveyor rack. At this time, the telescopic end of the electric push rod is in an extended state, and each cooling fan blows toward the multiple PCB boards on the electric discharge conveyor rack (there are gaps between adjacent PCB boards), thereby cooling down the multiple PCB boards (since the tin melting furnace is lower than the level of the PCB board, the cooling fan will not affect the welding work of the tin melting furnace). When the PCB board approaches the discharge port under the transportation of the electric discharge conveyor rack, the telescopic end of the electric push rod contracts, thereby driving the mounting frame and the cooling fan to move upward to avoid affecting the unloading of the PCB board.

When the PCB board 35 is about to approach the tin melting furnace 6, the electric feeding and conveying frame 4 stops transporting the PCB board 35. Then, the rotating frame 7 moves downward with the double-axis cylinder 8, the connecting rod 9 and the clamping claw 10 under the action of the lifting unit until the PCB board 35 is located between the two clamping claws 10. Then, the telescopic end of the double-axis cylinder 8 contracts, prompting the two clamping claws 10 to clamp the PCB board 35.

During this process, the pressing plate 23 moves downward with the double-axis cylinder 8 until the pressing protrusion on the lower end surface of the pressing plate 23 contacts the upper end surface of the pin component. During this process, the spring 27 is squeezed and contracted, exerting a downward force on the pressing plate 23, the pressing protrusion and the pin component. On the one hand, it prevents the welding part of the pin component in an inclined state from shaking and deviating when it contacts the solder, affecting the welding quality. On the other hand, it prevents the PCB board 35 from shaking and deviating when adjusting the angle with the pin component, affecting the welding accuracy.
