Description

Technical Field

[0001] This utility model relates to the field of transmission mechanism technology, and in particular to a transmission mechanism for circuit board quality inspection. Background Technology

[0002] The quality of a circuit board after manufacturing directly affects whether the circuit can function properly after surface mount technology (SMT). If the circuit malfunctions due to poor circuit board quality, the losses outweigh the gains. Therefore, it's necessary to check the continuity between solder pads after production. However, current testing institutions can only perform single-sided testing, increasing the testing time and requiring manual placement of the circuit board in the testing position. Existing circuit board quality testing devices use axial flow fans for airflow and vibrate by tapping balls, and utilize the sealing of connectors for better and more intuitive quality testing. However, they cannot detect the aforementioned quality issues.

[0003] For example, the utility model patent with authorization announcement number CN 219777743 U discloses a transmission mechanism for circuit board quality inspection, which includes a C-shaped frame. An electric slide rail is fixedly connected to the right side of the top of the C-shaped frame. An electric slider is electrically connected to the top of the electric slide rail. A robotic arm is fixedly connected to the center of the top of the electric slider. A detection needle is fixedly connected to the top of the robotic arm. A gear is rotatably connected to the inner cavity on the right side of the C-shaped frame. A rack is movably connected to the left side of the inner cavity of the C-shaped frame. A guide block is provided on the top of the outer wall of the rack. However, the adjustability of the circuit board is limited, which makes the inspection inconvenient. In view of this, a transmission mechanism for circuit board quality inspection is proposed. Utility Model Content
