Description

Technical Field

[0001] The utility model relates to the technical field of circuit board detection, in particular to a control circuit board detection tool. Background Art

[0002] Circuit boards are the core components of electronic products, used to connect various electronic components, transmit signals and electricity, and realize various functions of the equipment. Circuit boards are usually made of conductive materials and have complex electronic components, wires and connection points on them. Their function is to carry and distribute current, control signal transmission, and perform specific functions. The correctness of the circuit board is crucial to the performance and reliability of electronic products. When a circuit board fails, it needs to be inspected and repaired using the detection probe on the detection equipment.

[0003] Publication No. CN221667827U discloses a positioning structure for circuit board detection. By providing elastic limiting members and elastic edge members, the circuit board to be positioned can be placed on the positioning seat so that it is placed between the two limiting blocks. Then, according to the size of the circuit board, the position of the insertion rod in the insertion cavity is adjusted, and the distance between the two elastic edge members on the limiting block is adjusted. After the adjustment is completed, the position of the insertion rod can be fixed by the elastic limiting member. Then, the two limiting blocks can be driven closer to each other by the driving member so that the elastic edge members abut against the sides of the circuit board, thereby fixing the four corners of the circuit board and completing the positioning of the circuit board. By introducing the elastic edge members, this structure realizes precise positioning and rapid alignment of the circuit board, and can also position circuit boards of different sizes. However, the following problems still exist in the actual use of this patent:

[0004] Although this positioning structure for circuit board inspection drives the two limit blocks to approach each other through a driving member, so that the elastic clamping edge member abuts against the side of the circuit board, thereby fixing the four corners of the circuit board and completing the positioning of the circuit board, it is not convenient to adjust the angle of the circuit board, and thus it is impossible to perform quality inspection on components at certain tricky angles on the circuit board.

[0005] A control circuit board detection tool is proposed to solve the above problems. Utility Model Content

[0020] 1. By setting up an adjustment mechanism, the angle of the circuit board can be adjusted according to actual conditions, which facilitates the quality inspection of components in positions with more difficult angles and improves the practicality of the device. The driving motor drives the active wheel to rotate, and the meshing action between the active wheel and the first driven wheel is used to drive the first driven wheel to rotate.
