Abstract
The utility model belongs to a multifunctional vacuum negative pressure machine used for manufacturing and debugging a resistance-type touch screen, which comprises a frame, a cylinder body, a cylinder cover, a primary pipeline, a one-way valve, a first vacuum pump, a secondary pipeline, a three-way valve, a second vacuum pump, an exhaust pipe and an exhaust hole which are sequentially and closely connected, wherein the cylinder body, the cylinder cover, a release valve, a release pipe and a silencer are communicated with one another; the cylinder body is internally provided with a tray; a motor is used for driving the cylinder cover to rotate for the seal connection with the cylinder body; wheels are arranged at the bottom of the frame; the cylinder cover can be closed by rotation of the motor; and the second vacuum pump is connected with the bottom of the cylinder body by the secondary pipeline, the three-way valve, the first vacuum pump, the primary pipeline and the one-way valve. The multifunctional vacuum negative pressure machine is provided with the first vacuum pump, the second vacuum pump, the one-way valve and the three-way valve, thus not only being rapid in exhaustion rate and high in negative pressure limit value, but also having the effect of maintaining the pressure when saving the energy since the second vacuum pump is directly connected with the cylinder body by the three-way valve when the first vacuum pump is closed.
Description
Technical field
The utility model belongs to a kind of multifunctional vacuum Negative pressure machine that is used for the making and the debugging of resistive touch screen.
Background technology
In the flourishing epoch of this communication, mobile phone has become the requirement of people's daily life and work, and touch-screen also will be with it intuitively, simply, advantage begins progressively alternative original key mobile phone efficiently.Touch-screen is a kind of remarkable input equipment that improves man machine operation interface, and it has obtained to use widely in many electronic products, such as mobile phone, PDA, multimedia, public information inquiry system etc.And in the middle of the touch-screen industry; The film drum is a technology difficult problem of membrane combination up and down always; We can reduce the film drum through changing board air pressure and temperature according to usual method, but we can find can the touch-screen diaphragm soft stress test step of back to be exerted an influence like this.Temporarily also do not regulate the equipment of gasbag pressure at present in the touch-screen industry, the too high semi-finished product of gasbag pressure can only directly be scrapped.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of the utility model is to provide a kind of multifunctional vacuum Negative pressure machine that is used for the making and the debugging of resistive touch screen.
To achieve these goals; The utility model adopts following technical scheme: a kind of multifunctional vacuum Negative pressure machine; It closely is connected with framework, cylinder body, cylinder cap, pipeline, check valve, first vavuum pump, secondary pipeline, triple valve, second vavuum pump, blast pipe, exhaust outlet successively, and said cylinder body, cylinder cap, relief valve, releasing tube, muffler communicate, and are provided with pallet in the cylinder body; Motor drives the cylinder cap rotation and is tightly connected with cylinder body, and base of frame is provided with wheel.The cylinder cap of telling is the motor rotary closing.Second vavuum pump is connected with cylinder base through secondary pipeline, triple valve, first vavuum pump, pipeline, a check valve.Cylinder body right side and relief valve, muffler are connected to form release.
The beneficial effect of the utility model is: this multifunctional vacuum Negative pressure machine is provided with first vavuum pump, second vavuum pump, check valve, triple valve; Possess not only that the speed of evacuation is fast, the negative pressure limiting value is big; Can also lead to first vavuum pump cuts out; Second vavuum pump directly is connected with cylinder body through triple valve, in energy-conservation, also possesses the effect that pressure is kept.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with Fig. 1 the utility model is detailed: a kind of multifunctional vacuum Negative pressure machine; It closely is connected with framework 1, cylinder body 8, cylinder cap 7, pipeline 4, check valve 5, first vavuum pump 2, secondary pipeline 14, triple valve 3, second vavuum pump 16, blast pipe 15, exhaust outlet 13 successively; Said cylinder body 8, cylinder cap 7, relief valve 12, releasing tube 11, muffler 10 communicate; Be provided with pallet 6 in the cylinder body 8; Motor 9 drives cylinder cap 7 rotations and is tightly connected with cylinder body 8, and framework 1 bottom is provided with wheel 17.
Different according to material properties and product structure, this multifunctional vacuum Negative pressure machine can switch the speed of selecting the speed of evacuation and the height of pressure to first vavuum pump and second vavuum pump.
