Description

Technical Field

[0001] The utility model relates to the technical field of electronic assembly auxiliary instruments, in particular to a PCB board suction machine for processing to prevent falling. Background Art

[0002] A PCB board suction machine for processing is an automatic device used to suck, transport and place PCB boards during the production process of PCB boards. The working principle of the PCB board suction machine for processing is mainly based on vacuum adsorption technology. The suction cup generates negative pressure through a vacuum pump to suck the PCB board. The suction cup is moved to a specified position by a robotic arm, and the vacuum force is cut off to make the PCB board freely fall to the ground or be placed at the specified position, realizing the precise suction and placement of all PCB boards.

[0003] When the traditional suction machine is in use, the PCB board is adsorbed by the negative pressure formed by the air pump cooperating with the suction cup. For PCB boards with relatively dense openings or uneven surfaces, the adsorption strength of the negative pressure suction machine for such PCB boards will be reduced. During the transfer process of the PCB board, the vibration of the equipment will cause the PCB board to vibrate, and it is easy for the PCB board to fall from the negative pressure suction machine.
