[0051] Usage process

[0052] One or more PCB board bodies 11 are placed in the positioning groove 12. The positioning component 13 is a single or combined positioning structure formed by one or more positioning pins / blocks / holes. After the positioning component 13 on the positioning groove 12 positions the board body 11, the transfer fixture 1 is moved onto the positioning assembly 4. The limiting block 46 on the positioning base 41 passes through the limiting hole to guide the transfer fixture 1. At the same time, the limiting block 46 on the positioning base 41 also supports the board body 11, so that the air suction hole 16 on the transfer fixture 1 is... The vacuum suction cup 45 on the adsorption plate 43 is connected to a vacuum generator to generate negative pressure, which indirectly adsorbs the board 11 onto the suction hole 16 to achieve positioning of the board 11. This holds the PCB board 11 in place to prevent it from floating, and then solder paste is printed to ensure processing accuracy. After the solder paste printing is completed, the positioning base 41 is separated from the transfer fixture 1, the pressure plate 2 is placed on the transfer fixture 1, and the slider 32 on the connecting plate 31 is pressed, so that the two sliders 32 compress the spring 36. The locking block 33 passes through the locking mechanism. After the hole is opened, the reaction force of the spring 36 causes the locking block 33 to lock onto the locking hole, forming a snap-fit ​​structure, which realizes the quick connection between the pressure plate 2 and the transfer fixture 1. At this time, the positioning protrusions 24 around the fixing groove 23 press the processing position of the plate 11 onto the positioning groove 12, so that electronic components can be mounted on the plate 11. After the electronic components are mounted, the upper pressure plate 5 is placed on the pressure plate 2, and the positioning rod on it passes through the positioning hole to realize the quick positioning of the upper pressure plate 5. The pressure block 53 has magnetic material or is made of magnetic material. Made of materials, the pressure block 53 is magnetically connected to the pressure plate 2, thereby pressing the mounting position of the board 11 after electronic components are mounted onto the transfer fixture 1. At the same time, the guide blocks 62 at both ends of the push rod move along the guide groove 17 toward the board 11. The side push rod 61 is set opposite to the side of the board 11. The side push rod 61 on the side push block 6 pushes and positions the mounting position of the board 11 to ensure the positional accuracy of the board 11 after electronic components are mounted. Then it is sent to the reflow oven for solder paste soldering, thereby completing the electronic component mounting and soldering.
