The main purpose of such a setting is to be able to refill the circuit board without affecting the normal loading of the circuit board, thereby greatly reducing the downtime caused by refilling, and finally achieving the improvement of the efficiency of circuit board loading.

[0031] In the embodiment, the two material storage platforms 21 are preferably connected together by a connecting plate 23 and driven by the same translation drive mechanism 12, so as to achieve synchronous change of the positions of the two material storage platforms 21; in other embodiments, the two material storage platforms 21 may also be unconnected and driven by different translation drive mechanisms 12.

In addition, the first camera 17 can perform a rough detection of the position of the circuit board to prevent the second suction nozzle 325 from being adsorbed to the hole position on the circuit board and affecting the stable adsorption.
