Abstract
The utility model discloses a kind of positive pressure detection devices of dust free room, including an air bag and the switch being connect with the air bag, the switch includes a PP piece and a stainless steel substrates, one end of the PP piece is connect with described stainless steel substrates one end by an electric wire, one copper sheet, the copper sheet that the other end setting one of the PP piece is connect with the electric wire are set on the other end of the stainless steel substrates；The air bag is connect with the PP piece, and the air pressure inside of the air bag is equal with the setting pressure of dust free room;Pass through the switch of the air pressure inside air bag controlled equal with dust free room setting pressure, when dustless room pressure is less than setup pressure value, air bag expansion, it closes the switch, when dustless room pressure is greater than or equal to setting value, switch is opened, and realizes the detection to dustless room pressure, and then realize the control to foreign matter source in dust free room.
Description
Technical field
The utility model relates to a kind of positive pressure detection devices of dust free room.
Background technique
At this stage, electronic equipment is increasingly various, and PCB is one of the important component of various electronic equipments, so in the life of PCB
There is very strict requirement during producing, wherein the environment and air quality of production PCB dust free room are all very important finger
It marks, for the main workshop of riveted in PCB plate lamination technology in dust-free room, dust-free room is normal in addition to guaranteeing in process of production
The control of dust fall two requires, and there are also the requirement of positive pressure production, the air pressure of so-called positive pressure, that is, dust free room be should be greater than outside dust-free room
Pressure just can guarantee that the foreign matter of dust-free room will not be recycled to dust free room in this way.
In the layout design of traditional pressing dust-free room, no positive pressure detection, when the pressure outside dust free room is greater than dustless
When indoor, foreign matter is flowed into dust-free room by air, can wait for various foreign matters anti-pcb board of being stained in the plank of riveted,
The interior bad appearance such as short is had after the completion of pressing in this way.
Utility model content
In order to solve problems in the prior art, the utility model embodiment provides one kind and is mounted on dust-free room pressure minimum
Position be used to detect and control dust-free room pressure dust free room positive pressure detection device, can ensure that dustless room pressure is full
Foot production needs, and improves product qualification rate, and provide the high-quality air conducive to health for operator.
In order to achieve the above objectives, a technical solution of the utility model is as follows:
A kind of positive pressure detection device of dust free room, including an air bag and the switch being connect with the air bag, the switch packet
A PP piece and a stainless steel substrates are included, one end of the PP piece is connect with described stainless steel substrates one end by an electric wire, described stainless
One copper sheet, the copper sheet that the other end setting one of the PP piece is connect with the electric wire are set on the other end of steel disc；The air bag
It is connect with the PP piece, and the air pressure inside of the air bag is equal with the setting pressure of dust free room.
It further, further include a warning device, the warning device is arranged on the electric wire.
Another technical solution of the utility model is as follows:
A kind of positive pressure detection device of dust free room, including an air bag and a switch, the switch include a PP piece and a bronze medal
Piece, one end of the PP piece are connect with described copper sheet one end by an electric wire, other end setting one and the electricity of the PP piece
The copper sheet of line connection；The air bag is connect with the PP piece, and the setting pressure phase of the air pressure inside of the air bag and dust free room
Deng.
The technical solution provided by the embodiment of the utility model gas equal with dust free room setting pressure by an air pressure inside
The switch of capsule control, when dustless room pressure is less than setup pressure value, air bag expansion is closed the switch, when dustless room pressure
When more than or equal to setting value, switch is opened, and realizes the detection to dustless room pressure, and then realize to foreign matter in dust free room
The control in source.
