Description

Technical Field

[0001] The present invention relates to the technical field of circuit board packaging, and particularly relates to an automatic test packaging device and method for a power circuit board. Background Art

[0002] Before and after the power circuit board is packaged, it needs to be detected to timely discover possible problems such as soldering joints, short circuits, air bubbles in packaging materials, and component offsets in the circuit board. At the same time, to ensure the performance of the circuit board, it is necessary to detect the electrical performance and heat dissipation of the circuit board to improve the yield rate of products; for the purpose of hardware protection of the circuit board, some circuit boards will be immediately packaged after detection.

[0003] For example, Chinese Patent CN115343597B discloses a packaging test device for a circuit board. The device realizes the turning of the circuit board through the cooperation of a spiral guide chute and an eccentric wheel, so as to facilitate the double-sided detection of the circuit board; an infrared temperature measurement probe board continuously monitors the temperatures of both sides of the circuit board.

[0004] However, before the power circuit board is packaged, different detections need to be carried out in sequence, and different equipment is required. It is difficult for this device to continuously carry out different detections; it is difficult to automatically sort the circuit boards during detection on the conveyor line; and during the process of multiple continuous detections of the circuit board, after the previous detection is unqualified, the subsequent detection will be empty for one round; it is difficult to automatically make up positions on the conveyor line, affecting the detection efficiency.

[0005] Based on this, the present invention designs an automatic test packaging device and method for a power circuit board to solve the above problems. Summary of the Invention
