Embodiment
It is to be understood that specific embodiment described herein is only in order to explain the utility model, and it is not used in restriction the utility model.
See Fig. 1, Fig. 2, it is proposed to vacuum sucking device one embodiment of the present utility model, the vacuum sucking device of the present embodiment, for drawing printed circuit board (PCB) (PCB), is particularly useful for drawing the printed circuit board (PCB) of band ink. Described vacuum sucking device comprises pedestal 11, is installed on the vacuum generating device of pedestal 11 and covers the sponge pad 13 of pedestal 11 bottom surface, and sponge pad 13 can be adhered to pedestal 11 bottom surface by viscose glue. Vacuum generating device comprises the parts such as vacuum generator 121, vacuum breaker, tensimeter 122, and vacuum generator 121 and vacuum breaker are installed on pedestal 11 inside or are wholely set with pedestal, and it is outside that tensimeter 122 is installed on pedestal 11. Pedestal 11 bottom surface is provided with multiple pore 111, this pore 11 is connected with the vacuum generator 121 of vacuum generating device, the position of the corresponding pore 111 of sponge pad 13 is provided with through hole 131, namely has some through holes 131 on sponge pad 13, with each pore 111 exposed on pedestal 11 bottom surface.
As shown in Figure 3, when vacuum sucking device draws printed circuit board (PCB) 20, sponge pad 13 contacts with printed circuit board (PCB) 20, in vacuum state in the through hole 131 of sponge pad 13, printed circuit board (PCB) 20 is produced adsorptive power F, draws printed circuit board (PCB) 20. Owing to sponge pad 13 is soft, therefore it is not easy to produce impression on printed circuit board (PCB) 20 surface, reduces the fraction defective of printed circuit board (PCB) 20.
The probability producing impression on printed circuit board (PCB) 20 surface in order to reduce further, it is necessary to reduce the pressure on printed circuit board (PCB) 20 surface. According to physical equation " pressure=by power/stressed area " it will be seen that for reducing pressure, realize by power and increase stressed area by reducing. , it is possible to reduce air pressure or vacuum tightness that vacuum generating device produces, therefore or/and increase the area of pedestal 11 bottom surface.
