Description

Technical Field

[0001] The utility model relates to the technical field of chip mounters, in particular to a vacuum nozzle carrier motion mechanism in a demagnetization device. Background Art

[0002] A placement machine is a device that accurately places surface mount components on PCB pads by moving the placement head. The suction nozzle, as a form of mobile placement head, can effectively absorb surface mount components. The principle is that after the placement machine nozzle contacts the electronic components, the air inside the nozzle is sucked out, and the external pressure is greater than the internal pressure of the nozzle, forming a negative pressure. Under the action of atmospheric pressure, the electronic components are pressed against the surface of the nozzle. At present, the general placement machine nozzle will generate magnetism during production operation, which will affect the quality of the product and the efficiency of production. Therefore, the nozzle needs to be cleaned regularly and demagnetization equipment should be used to eliminate the magnetism of the nozzle.

[0003] Existing demagnetization equipment usually uses a demagnetizer to eliminate the magnetic force of the suction nozzle. The placed suction nozzle is demagnetized by the reciprocating motion of the carrier and then cooperates with the demagnetizer. However, the existing carrier is usually pushed back and forth manually. This method is not only labor-intensive, but also has uneven speeds during manual pushing and pulling, which can easily reduce the demagnetization efficiency of the suction nozzle.
