Description

Technical Field

[0001] The utility model relates to the technical field of swing plate mechanisms, in particular to a variable-pitch swing plate mechanism. Background Art

[0002] Usually, after the whole PCB is assembled with components, the whole PCB is cut into individual PCB products by laser cutting equipment, which are then collected and output by a conveying mechanism. The individual PCB boards are then tested to determine whether they are operating normally in order to distinguish between good and defective products. The good products are then collected on trays and the defective products are recycled.

[0003] In the existing tray placement mechanism, due to the different placement distances between the two PCB boards on the material tray and the detection mechanism, most of them can only use a single robot / single suction cup to deliver the PCB products one by one to the detection mechanism for detection and then place the good and defective products on the tray one by one. The tray placement efficiency is low, which affects the production efficiency. Utility Model Content
