Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board mounting auxiliary bracket. Background Technology

[0002] When performing surface mount technology (SMT) on a circuit board, the circuit board needs to be fixed in place before the relevant SMT operations are performed.

[0003] A patent document with publication number CN214723676U discloses a CNC circuit board clamping mechanism. This patent first assembles the various components, placing the circuit board on top of a placement table. A servo motor drives a rotating screw, while a moving block moves along the outer surface of the rotating screw, thereby moving a connecting block, clamping base plate, fixing block, telescopic rod, and clamping top plate. When one end of the clamping top plate contacts one end of the circuit board, the circuit board presses against the inclined surface of the clamping top plate, causing the clamping top plate to move the telescopic rod upwards. Simultaneously, it moves the movable rod and mounting plate upwards, allowing the mounting plate to compress the force spring. Under the action of the spring, the mounting plate and movable rod drive the telescopic rod and clamping top plate to move downward, thereby restricting the top of the circuit board. When the circuit board is pressed against the clamping top plate, one end of the circuit board can move in the direction of the fixed block. The fixed block can restrict one end of the circuit board and clamp the circuit board. Although this patent can clamp the circuit board, when performing surface mount operations on the circuit board, it is sometimes necessary to process both sides of the circuit board. Due to the overall structure, this mechanism can only process one side of the circuit board at a time. When processing the other side, the circuit board must be removed, flipped, and fixed for processing again. The operation is not continuous, which reduces its practicality.

[0004] Therefore, it is necessary to provide a circuit board mounting auxiliary bracket to solve the above-mentioned technical problems. Utility Model Content
