How to troubleshoot common faults in high-speed pick and place machines? such as Used SMT Samsung SM310 pick and place machine, Juki pick and place machine and Yamaha pick and place machine.

The high-speed pick and place machine error components are taken out from the packaging tape by the high-speed moving patch head. During the process of mounting on the printed board, there are several failures such as unacquired, lost after suction, etc. Failures can cause a large amount of component loss. According to our experience, component suction is usually caused by the following reasons:

Samsung SM310 pick and place machine

(1) The vacuum pressure of the Yamaha pick and place machine is insufficient. When the nozzle takes the component, a certain negative pressure is generated at the nozzle to attract the component to the nozzle. The Yamaha pick and place machine determines whether the nozzle pick up component is abnormal or not. In the negative pressure detection mode, when the detection value of the negative pressure sensor is within a certain range, the machine considers that the suction is normal, and vice versa.

(2) The nozzle of the Yamaha pick and place  machine is worn out, and the nozzle is deformed, blocked, or damaged, resulting in insufficient air pressure, resulting in the absorption of components. Therefore, the degree of wear of the nozzle should be checked regularly and replaced.

(3) The problem of juki pick and place machine high-speed pick and place machine, some manufacturers have the quality problem of the chip component packaging, juki pick and place machine such as the pitch hole error is large, the adhesion between the paper tape and the plastic film Large, too small trough sizes are all possible causes of component failure.

(4) The impact of the height of the juki pick and place machine, the ideal suction height is 0.05mm when the nozzle is in contact with the surface of the component. If the depth of the pressing is too large, the juki pick and place machine will cause the component to be pressed. Instead of feeding in the feed trough. If the suction condition of a component is not good, the suction height can be adjusted slightly upwards, for example, 0.05 mm.

(5) The influence of the feeder of the Samsung SM310 pick and place machine , the feeding of the feeder is poor, the deformation of the pressure belt cover, the spring and other running mechanisms, and the rust damage, etc., the Samsung pick and place machine causes the components to be biased, the vertical piece or Can not afford the device, Samsung SMT machine should be regularly checked, and found that the problem is dealt with in time, so as not to cause a lot of waste of the device.
