[0002] Printed circuit board, also known as printed circuit board, printed circuit board, often uses the English abbreviation PCBA, is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components.

[0003] PCBA needs to be processed during the production process. However, when the existing placement machine is performing placement on the PCBA, the staff needs to manually take the PCBA out of the placement machine after the placement is completed. The PCBA cannot be automatically collected and processed in a centralized manner, which results in the staff's hands inevitably coming into contact with the PCBA. For a period of time after the PCBA is completed, some toxic substances will exist on its surface. If the staff directly takes it, they may not only inhale the toxic substances into their bodies, but also come into direct contact with the toxic substances. Therefore, a more complete placement machine for PCBA production is needed to solve the above-mentioned problems. Utility Model Content

[0006] Furthermore, a limit plate is fixedly sleeved below the surface of the trapezoidal rod, the sliding plate is located above the limit plate, and a spring is movably sleeved on the surface of the trapezoidal rod above the sliding plate. When the spring is not subjected to external force, the pressing rod will press down and fix the two sides of the PCBA in the placement groove, and a rubber ball is fixed to the bottom end of the pressing rod.

[0007] Furthermore, a first positioning plate and a second positioning plate are fixedly connected to the rear side of the inner wall of the auxiliary box, the servo motor is located between the first positioning plate and the second positioning plate, and the first positioning plate and the second positioning plate can limit the position of the cylinder.

[0008] Furthermore, a circular groove is provided on the bottom surface of the collecting box, a driving motor is fixedly connected to the bottom of the inner wall of the auxiliary box body, a rotating plate located in the circular groove is fixedly connected to the output end of the driving motor, the outer peripheral side surface of the rotating plate is tightly attached to the inner wall peripheral side of the circular groove, and the top surface of the rotating plate is flush with the bottom surface of the inner wall of the collecting box.

[0012] After the PCBA is mounted, the utility model can automatically collect and process the PCBA in a centralized manner, so that the staff can avoid direct contact with the PCBA that has just been mounted. The specific operation is that after the PCBA is mounted, the cylinder is opened to allow the piston rod of the cylinder to retract inward, so that the lifting plate moves from the main box to the sub-box. At this time, the cylinder is closed and the servo motor is opened in reverse, and the servo motor allows the cylinder to rotate in the reverse direction until the cylinder is stuck by the second positioning plate and then the servo motor is closed. At this time, the PCBA in the placement slot will slide out of the second slot and fall into the collection box, and then the servo motor is opened in a positive direction to allow the cylinder to return to a vertical state. After returning, the cylinder is opened again to allow the piston rod of the cylinder to extend outward, so that the lifting plate enters the first slot. The above operation is repeated, and the finished PCBA can be collected in a centralized manner after the PCBA is mounted. After the centralized collection is completed, the second box door is opened to ventilate the PCBA in the collection box. BRIEF DESCRIPTION OF THE DRAWINGS
