[0024] During implementation, after the collection is completed, the user pulls the collection frame 112 again, so that the collection frame 112 drives the positioning card 31 away from the inside of the positioning card slot 32. At this time, the positioning card 31 slides inside the guide slide 333, and the positioning card 31 is guided by the guide slide 333. At this time, the arc-shaped card 332 is driven to move toward the inside of the positioning card 31 under the elastic force of the telescopic spring 331.

[0025] Working principle: When in use, first place the rack 1 at the designated position, the user places the circuit board body 104 to be mounted on the surface of the feed conveyor belt 103, and the circuit board body 104 is conveyed under the action of the feed conveyor belt 103. Then, the user operates the controller 101, so that the controller 101 controls the first electric push rod 110 on the surface of the moving plate 118 to work, and under the action of the first electric push rod 110, the lifting plate 109 and the conveyor belt 108 are driven to move downward, so that the conveyor belt 108 moves downward until it is flush with the surface of the feed conveyor belt 103, so that the circuit board body 104 can be It can be transported to the surface of the conveyor belt 108. Then, the user operates the controller 101 to control the servo motor 117 inside the fixed frame 114 to work. Under the action of the servo motor 117, the lead screw 113 is driven to rotate inside the fixed frame 114. When the lead screw 113 rotates inside the fixed frame 114, the threaded joint of the lead screw 113 and the adjusting screw 116 drives the adjusting screw 116 to move inside the fixed frame 114. At this time, the adjusting screw 116 drives the movable plate 118 to move left and right inside the frame 1. When the movable plate 118 moves, the movable plate 118 drives the lifting The plate 109 and the conveyor belt 108 move left and right inside the rack 1. At this time, the conveyor belt 108 drives the circuit board body 104 to move slightly left and right inside the rack 1. Then, the user operates the controller 101 again, so that the controller 101 controls the second electric push rod 115 to work. Under the action of the second electric push rod 115, the fixed frame 114 is driven to move back and forth inside the rack 1. When the fixed frame 114 moves back and forth, the fixed frame 114 drives the movable plate 118 and the conveyor belt 108 to move back and forth inside the rack 1, thereby driving the circuit board body 104 to move back and forth, adjusting the position of the circuit board body 104. The position is adjusted, and the surface of the circuit board body 104 is subjected to placement processing under the action of the placement head 106. After the processing is completed, the controller 101 is operated again, so that the controller 101 controls the first electric push rod 110 on the surface of the movable plate 118 to work, and the lifting plate 109 and the conveyor belt 108 are driven downward by the action of the first electric push rod 110, so that the conveyor belt 108 moves downward until it is flush with the discharge conveyor belt 111, and then the circuit board body 104 after placement moves to the surface of the discharge conveyor belt 111, and the circuit board body 104 after placement is discharged under the action of the discharge conveyor belt 111.

[0026] Subsequently, when the circuit board body 104 moves to the surface of the conveyor belt 108, the spring body 22 on the inner wall of the positioning frame 21 and the telescopic column 232 drive the clamping plate 231 and the pressure plate 233 to move, so that the clamping plate 231 drives the pressure plate 233 to move downward until it contacts the surface of the circuit board body 104. Under the joint action of the clamping plate 231 and the pressure plate 233, the circuit board body 104 is pressed and fixed on the surface of the conveyor belt 108, avoiding the displacement of the circuit board body 104 during mounting, so as to realize the function of the mounting machine to limit the circuit board body 104, so that the mounting machine can press and fix the circuit board body 104 on the surface of the conveyor belt 108 when in use, avoiding the displacement of the circuit board body 104 when the mounting machine is mounting on the surface of the circuit board body 104.

[0027] Subsequently, the discharge conveyor belt 111 conveys the mounted circuit board body 104 to the interior of the collection frame 112, and the mounted circuit board body 104 is collected in a centralized manner under the action of the collection frame 112. After the collection is completed, the user pulls the collection frame 112 again, so that the collection frame 112 drives the positioning card 31 away from the interior of the positioning card slot 32. At this time, the positioning card 31 slides inside the guide slot 333, and the positioning card 31 is guided by the guide slot 333. At this time, the arc card is driven by the elastic force of the telescopic spring 331. The arc-shaped clamp 332 moves toward the inside of the positioning clamp 31. At this time, the arc-shaped clamp 332 is away from the inside of the discharge conveyor belt 111, thereby removing the collection frame 112 from the surface of the rack 1, and processing the circuit board bodies 104 after being mounted in the collection frame 112, so as to realize the function of the placement machine to centrally collect the mounted circuit board bodies 104, so that the placement machine can centrally collect the mounted circuit board bodies 104 when in use, making it more convenient for the placement machine to collect the mounted circuit board bodies 104, and finally completing the use of the placement machine.
