Description

Technical Field

[0001] The utility model relates to the field of detection, in particular to a PCBA module detection device. Background Art

[0002] Visual inspection is to use a machine to replace the human eye for measurement and judgment.

[0003] Discriminate the situation of items through a visual sensor, which is a valuable mechanism for production, assembly or packaging.

[0004] It has inestimable value in the function of detecting defects and preventing defective products from being delivered to consumers.

[0005] After the PCBA module is produced, in order to facilitate sales, it is necessary to detect the PCBA module to avoid damaged PCBA modules from flowing into the market. The detection of the PCBA module generally includes two-sided detection, the detection of electrical components on the front side, and the detection of solder joints on the back side. The traditional detection method generally uses a fixture to clamp the PCBA module. In order to complete the two-sided detection, the fixture needs to drive the PCBA module to flip, and then complete the detection. When detecting the PCBA module by clamping it with a fixture, the clamping position of the fixture is blocked by the fixture and cannot be detected. At the same time, when flipping, in order to avoid the PCBA module from falling, it is necessary to increase the clamping force. Therefore, the clamping position of the PCBA module is easily damaged.
