Description

Technical Field

[0001] This utility model relates to the field of circuit board precision positioning technology, and in particular to a circuit board precision positioning mechanism. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board and is one of the most important components in the electronics industry. Almost every electronic device, from small items like electronic watches and calculators to large systems like computers, communication devices, and military weapons systems, uses PCBs to enable electrical interconnection between integrated circuits and other electronic components.

[0003] Announcement No. CN 222038720 U discloses a circuit board precision positioning mechanism, including a base plate, two side plates fixed on the upper surface of the base plate, two slide rails fixed between opposite sides of the two side plates, a moving component disposed between opposite sides of the two slide rails, a fixing component disposed on the upper surface of the base plate, the fixing component including a motor fixed to the upper surface of the base plate, a threaded rod fixed to the output end of the motor, two support seats rotatably connected to the outer side of the threaded rod, and two fixing plates threadedly connected to the outer side of the threaded rod;

[0004] When in use, existing devices can only clamp the two sides of the circuit board, which has a small clamping range. In addition, during the processing, the operator needs to adjust the angle and position multiple times, which results in low work efficiency. Therefore, we propose a circuit board precision positioning mechanism. Utility Model Content

[0015] By adopting the above technical solution, protective pads are provided at the bottom of the pressure positioning plate and above the bottom inner wall of the mounting frame. A portion of the circuit board is not equipped with circuitry, allowing the pressure positioning plate to abut against it. This makes it less likely for the circuit board to be damaged when the device presses down and fixes it.
