Definitions
- the present invention relates to a micro diaphragm pump formed by laminating and joining a plurality of thin metal plates having patterns such as a valve plate, a valve seat, and a diaphragm.
- Patent Document 1 discloses a flat in which a pump body is provided with an inflow valve and an outflow valve with a valve element sandwiched between a metal out bush (first cylindrical portion) and an in bush (second cylindrical portion).
- a micropump arranged to be orthogonal to a pressure chamber.
- the diaphragm which forms a pressure chamber here is arrange
- a pressure chamber (diaphragm chamber) is provided between the suction valve and the discharge valve, and the pressure in the pressure chamber is changed by a piezo element attached to the diaphragm that defines the pressure chamber.
- a pump that discharges is shown. That is, the diaphragm does not cover the suction valve and the discharge valve (is in contact with one side surface of both valves).
- a silicon substrate is partially used.
- JP 2009-236284 A Japanese Patent Laid-Open No. 2006-161779 JP-A-6-93972 Japanese Patent Laid-Open No. 5-1669 JP-A-10-299659
- An object of the present invention is to provide a highly reliable micro-diaphragm pump that can increase suction force and discharge force, increase the degree of freedom in material selection without being restricted to a silicon substrate.
- a first object is a micro-diaphragm pump having a diaphragm chamber that is in contact with one side of an intake valve and a discharge valve, wherein one of the valve plates of the intake valve and the discharge valve and a flow path of the other valve And two valve plate sheets laminated in a direction in which the valve plate and the flow channel opening face each other, and the valve of the one valve plate sheet laminated on both surfaces of the laminated body
- Two valve seat seats formed with a valve seat facing the plate and a valve stopper facing the valve plate of the other valve plate seat, and superimposed on one valve seat seat and communicated with the intake valve and the discharge valve, respectively
- a base plate having two flow paths, a frame that is superimposed on the periphery of the other valve seat and surrounds the suction valve and the discharge valve, and a valve seat that is superimposed on the frame and overlaps the frame
- a diaphragm that forms a diaphragm chamber between them
- the two valve plate seats and the two valve seat seats are made of a thin metal plate such as stainless steel, and if they are joined in multiple layers, there is no need to use a relatively expensive silicon substrate. It is recommended to select a metal that will not corrode the fluid.
- solder with high Sn (tin) concentration or silver alloy solder plating such as Sn-Ag is used in terms of wettability and soldering strength to stainless steel.
- Various methods such as adhesives and metal diffusion bonding can be used.
- the valve plate is structured to be held by a support arm extending from the inner edge of the valve plate opening formed in the valve plate sheet to the inner diameter side, and becomes a flow path opening formed in the valve plate sheet and a flow path of the discharge valve formed in the base plate.
- the opening diameter of the flow path opening is preferably equal to (including substantially equal to or substantially equal to) the inner diameter of the valve plate opening. In this case, it is necessary to laminate and pressurize when multi-layered valve plate seats and valve seats are used. At this time, no pressure is applied to the valve plate and its supporting arm, and these are joined to other sheets. Can be prevented.
- Valve plate sheet and valve seat sheet can be processed by various methods such as etching and press punching.
- etching and press punching various methods such as etching and press punching.
- these sheets can be manufactured efficiently.
- the frame and the diaphragm are made of thin metal plates, which are laminated on one side of the laminate formed in claim 2 (preliminary laminate), and a base plate is laminated on the other side of the laminate to join the pump. Can be formed. As described above, the assembly accuracy can be improved and the production efficiency can be improved by dividing the lamination of the valve plate sheet and the valve seat sheet and the lamination of the frame body, the diaphragm, and the base plate into two joints.
- This protrusion can be formed by leaving a portion that becomes a valve seat and slightly carving the periphery by half etching, but it may be formed by other methods. In this case, the contact pressure with respect to the protrusion of the valve plate is increased, and the sealing performance is improved. That is, the sealing performance as a valve is improved.
- DLC Diamond Like Carbon
- DLC includes a carbon structure with a good molecular structure and a diamond structure with a high hardness, and has the advantages of both. Therefore, the protrusion can be hardened and smoothed, and the wear resistance and durability are improved, and the sealing performance is improved.
- DLC processing is performed on the ridges in this way, the adhesion between the valve plate and the valve seat is further improved by stamping (pressing) the valve plate onto the ridges by utilizing the high hardness of DLC. Can be made. In order to make this stamping possible, an opening through which a processing tool (such as a punch) for stamping is passed is formed in the valve stopper.
- valve stopper is provided with an annular portion facing the ridge serving as the valve seat (and thus facing the valve plate) and a circumferentially divided flow path around the annular portion, and a stamping tool is inserted into the annular portion. That's fine.
- Piezo element is suitable for the drive element held in the diaphragm.
- a sintered body of a piezoelectric material that includes zircon / lead titanate (PZT) and is collectively called PZT, which is bonded to a diaphragm and polarized by applying an electric field.
- PZT zircon / lead titanate
- the movable area (movable space) of the drive element and the diaphragm can be secured inside the second frame, and the pump is mounted on a substrate or the like. When mounted on, the adjacent parts do not come into contact with each other and the pump operation is not hindered.
- the present invention can be expanded by expanding the area of the diaphragm to the outside of the suction valve and the discharge valve, the volume change of the diaphragm chamber can be increased to smoothly perform the fluid suction / discharge operation.
- the suction valve and the discharge valve are formed by overlapping two valve plate sheets and overlapping the valve seat sheets on both outer sides thereof, the whole can be made extremely thin and the pump can be miniaturized.
- the valve plate seat, valve seat seat, base plate, frame, and diaphragm can be laminated and joined (multi-layered joining), and the drive element can be attached to the diaphragm from the outside, resulting in high productivity and significant cost reductions. is there.
- valve plate seat and the valve seat can be stacked in the opposite direction if the combination of the two sheets constituting the intake valve and the combination of the two sheets constituting the discharge valve have the same shape. Therefore, in this case, the productivity is further improved.
- a plurality of pumps are formed simultaneously by preparing sheet-like members each formed with a valve plate sheet, valve seat sheet, base plate, frame, and diaphragm corresponding to a plurality of pumps, and laminating and joining them. Then, it is possible to cut the laminated body and divide it into individual pumps. In this case, the productivity is further improved.
- the diaphragm chamber (pressure chamber) and each valve are in contact with each other through one valve seat, the fluid flow path connecting the diaphragm chamber and each valve is extremely short, and the diaphragm when the diaphragm discharges fluid.
- the chamber volume can be made sufficiently small. That is, the ratio of (maximum volume / unnecessary volume) can be extremely increased. Therefore, the suction / discharge operation can be surely performed for each stroke of the diaphragm, and the management of the fluid discharge amount (flow rate) becomes accurate. Further, since the diaphragm area is large, the suction / discharge force of the fluid can be increased, and there is a possibility that it can be used not only for incompressible fluid (liquid etc.) but also for compressible fluid (gas etc.).
