Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of detection equipment, and particularly relates to a three-dimensional detection device for tin paste of finished circuit boards. BACKGROUND

[0002] The tin paste of a circuit board is mainly used for welding of electronic components such as PCB surface resistors, capacitors and ICs in the SMT industry. Before the finished circuit board is put into use, the thickness of the tin paste of the circuit board is detected, and the finished circuit board can be put into mass production only after meeting the standards.

[0003] When the thickness of the tin paste of the finished circuit board is detected, the circuit board usually needs to be fixed first, and then a camera detector is used to measure and analyze the thickness of the tin paste. However, for the double-cone type structure of the finished circuit board, the detection of the internal tin paste faces two prominent problems. First, the inclination angles of the outer walls on both sides of different models of double-cone type circuit boards are different, and corresponding clamps need to be replaced according to the specific angle during fixing, which is complicated and inefficient. Second, if the probe is not perpendicular to the surface of the tin paste when the camera detector is directly inserted into the board for measurement, the detection data is prone to deviation. At this time, the operator also needs to manually adjust the angle of the camera according to the inclination angle of the inner wall of the board, which is a complex process and greatly reduces the efficiency and reliability of the detection of the internal tin paste of the double-cone type finished circuit board.
