Description

Electric control air pressure valve and electric control air pressure valve selecting device of high-speed tiny parts Technical Field The invention relates to the field of control valves, in particular to an electric control air pressure valve and an electric control air pressure valve selecting device of high-speed tiny parts. Background As shown in fig. 1 and 2, with the development of optical sensors and high-speed imaging technologies, there is a higher demand for an air pressure valve that can be used for high-speed, stable and precise sorting of small components. In order to achieve efficient and stable air flow, it is necessary to set the air outlet direction with high accuracy. In the existing air pressure valve, the direction in the valve is mostly linear. When the air is injected into the air pressure valve, the air flow is ejected to impact the valve, and is discharged to the atmosphere in the 90 DEG direction, so that a time difference is generated between the air pressure valve and the opening and closing of the valve, and the instability of the opening and closing of the air is easily caused. When the tiny components are selected at high speed, the instability of air opening and closing is easy to cause the following problems: 1) The problem that defective products cannot be accurately removed; 2) The problem that good products and defective products are removed simultaneously; the air flow is typically fanned out as it exits through the small passageway. In the prior art, the air flow process encounters resistance (wall), and no straight flow is formed until the discharge port, so that air retention is generated. Therefore, the trapped air is somewhat sent to the S direction, the vacuum effect is reduced, and the selection of good products is affected to a certain extent. When the vacuum effect is reduced, the complete start-up time of the compressed air is naturally increased. Disclosure of Invention Therefore, the invention provides an electric control air pressure valve selecting device for realizing more effective control of air opening and closing by optimizing the air flow direction and high-speed tiny parts based on the above problems. The invention adopts the following technical scheme: The utility model provides an automatically controlled air pressure valve, includes an air chamber, and air chamber is main cavity body and toper chamber respectively, and main cavity body is connected with the less one end in toper chamber area, and the other end and the air inlet of main cavity body connect the intercommunication, and the mid portion and the air of air chamber are given vent to anger the joint intercommunication. And the air outlet connector is connected with the main cavity body at a certain angle. The shell is fixed on the body, and fixes on the outer body air inlet joint and air outlet joint, just be equipped with air speed regulator on the air inlet joint. The body is fixed with fixed block and adjusting block, and the one end of leaf spring is passed through the fixed block is fixed on the body, just the upper and lower both sides of leaf spring are fixed with a piezoelectricity electronic respectively, the other end of leaf spring is fixed with the silica gel pad. The silica gel pad can vibrate up and down under the drive of the plate spring, so that the conical cavity can be opened or closed. The utility model provides a device is selected to automatically controlled air pressure valve of small spare part of high speed, includes foretell automatically controlled air pressure valve, still includes straight track and the optical sensor that shakes, and compressed air's passageway flows from air outlet joint back and enters into straight track that shakes, the orbital top that shakes directly sets up optical sensor.
