Description

Technical Field

[0001] The utility model discloses an automatic device for removing SMT mounting caps, belonging to the technical field of system integration solutions. Background Art

[0002] For many connectors, if there is no customized special suction nozzle, it is necessary to add a mounting cap on the top of the component for the suction nozzle of the placement machine to pick up. However, this mounting cap is not needed for the product itself. At the same time, if the mounting cap is not removed, it will affect many quality risks such as subsequent assembly. Therefore, it is necessary to remove the SMT mounting cap, set the data through the touch screen, start the PLC control system, and the data during operation is displayed on the display screen. The transport device transports the PCBA to the stop position for positioning. The upper computer controls the industrial camera to take the actual picture of the product and identifies the positioning coordinates of the product through the coordinate algorithm conversion. The mark is then communicated with the robot through industrial control to import the product positioning coordinates, and finally the manipulator is controlled to move to the specified position. The PLC control system controls the pneumatic clamp installed under the manipulator to start sorting and removing the caps. In order to control the pneumatic clamp on the end of the manipulator to move smoothly, it is necessary to install oil-water separators, manifolds, solenoid valves and other components between the air source and the pneumatic clamp. The air source, oil-water separator, manifold, solenoid valve, and pneumatic clamp are interconnected by hoses. When the end of the hose falls off due to air pressure, it swings randomly under the action of the compressed gas in the hose, which can easily cause damage to other components and has poor safety.
