The first, regular meeting suction nozzle occurs and is difficult to be drawn onto the lip-deep phenomenon of PWB fully in the time of in actual operation, causes the suction value of PWB Acetabula device relatively poor, thereby causes PWB position instability.

The second, because the fixed-site in sucker hole can't be adjusted mobile, so can only adjust trial among a small circle when unusual sorption occurring, then can only use wherein some suction nozzles as invalid, other suction nozzles that can't use are sealed with adhesive tape, make that like this stability of PWB Acetabula device is poorer.

The utility model content

At above-mentioned defective, the purpose of this utility model is to provide a kind of Acetabula device, to solve the relatively poor and stable not enough defective of suction value of PWB Acetabula device in the prior art.

The utility model proposes a kind of Acetabula device, comprise in order to Acetabula device is fixed on holder on the board, sucker disk seat, in order to suction nozzle installing hole that suction nozzle is installed, in order to connect air flue, some screwed holes and some circular holes of air compressor machine, described screwed hole and described circular hole are distributed on the described holder, on described sucker disk seat, more increased the quantity of suction nozzle installing hole with respect to prior art, described suction nozzle installing hole is evenly distributed on sucker disk seat, and described sucker installing hole is screwed hole.

According to the described Acetabula device of the utility model preferred embodiment, it is characterized in that the quantity of described suction nozzle installing hole is 32.

Suction nozzle installing hole quantity of the present utility model is obviously more than the quantity of suction nozzle installing hole in the prior art, thereby also showed increased of its suction nozzle quantity.Like this, when switching the PWB material, need not change the equipment intrinsic parameter substantially, need only the position of mobile suction nozzle in appearance, thereby can stably grasp PWB, also greatly save the time, improve production efficiency.
