Description

Technical Field

[0001] This invention relates to the field of control valves, and more specifically to an electrically controlled air compressor valve and an electrically controlled air compressor valve selection device for high-speed micro-components. Background Technology

[0002] like Figure 1 , 2 As shown, with the development of optical sensors and high-speed camera technology, higher requirements are being placed on air pressure valves that can select tiny parts quickly, stably, and accurately.

[0003] To achieve efficient and stable airflow, the air outlet direction needs to be set with high precision.

[0004] Most existing air pressure valves have a straight internal direction.

[0005] Once air is introduced into this type of air compressor valve, the airflow impacts the valve, creating a backflow that is discharged into the atmosphere at a 90° angle. This creates a time difference with the valve's opening and closing, which can easily lead to instability in the air's opening and closing.

[0006] When performing high-speed sorting of tiny parts, the instability of the air opening and closing can easily lead to the following problems:

[0007] 1) The problem of not being able to accurately eliminate defective products;

[0008] 2) The problem of excluding both good and defective products at the same time;

[0009] When airflow is ejected through a narrow passage, it usually spreads outward in a fan shape.

[0010] In the existing structure, airflow encounters resistance (walls) during its flow, and it will not form a straight flow until it reaches the exhaust port, resulting in trapped air.

[0011] Therefore, some trapped air will be sent to the S direction, reducing the vacuum effect and affecting the selection of good products.

[0012] When the vacuum effect decreases, the time for the compressed air to start and stop completely increases. Summary of the Invention

[0013] Therefore, based on the above-mentioned problems, the present invention provides an air compressor valve and an electronically controlled air compressor valve selection device for high-speed micro-components that achieve more effective control of air opening and closing by optimizing the airflow direction.

[0014] The present invention adopts the following technical solution:

[0015] An electrically controlled air compressor valve includes an air chamber, which is divided into a main chamber and a conical chamber. The main chamber is connected to the smaller end of the conical chamber, the other end of the main chamber is connected to an air inlet connector, and the middle part of the air chamber is connected to an air outlet connector.

[0016] Furthermore, the air outlet connector is connected to the main cavity at a certain angle.

[0017] The outer shell is fixed to the main body, and the air inlet connector and air outlet connector are fixed on the outer body, and the air inlet connector is provided with an air speed regulator.

[0018] The main body is fixed with a fixing block and an adjusting block. One end of the leaf spring is fixed to the main body through the fixing block, and a piezoelectric element is fixed on the upper and lower sides of the leaf spring respectively. A silicone pad is fixed to the other end of the leaf spring.

[0019] The silicone pad can vibrate up and down under the action of the leaf spring, thereby opening or closing the conical cavity.

[0020] A high-speed micro-component electronically controlled air compressor valve selection device includes the aforementioned electronically controlled air compressor valve, as well as a linear vibration track and an optical sensor. Compressed air flows out from the air outlet connector and enters the linear vibration track, and the optical sensor is disposed above the linear vibration track.

[0021] The advantages of this invention are: through the above structure, this invention can more effectively control the start-stop time and supply of compressed air, so as to achieve high speed, stability and precise selection effect. Attached Figure Description

[0036] The specific embodiments of the present invention are further described below:

[0037] like Figures 3 to 11 As shown, this invention discloses an electrically controlled air compressor valve, comprising a housing 1, a fixing block 2, an adjusting block 3, an LED 4, a leaf spring 5, a piezoelectric element 6, a silicone pad 7, a body 8, an air outlet connector 9, and an air inlet connector 10. The housing 1 is fixed to the body 8, and the body 8 is provided with an air connector 9 and an air speed regulator 10. The fixing block 2 and the adjusting block 3 are fixed to the body 8. One end of the leaf spring 5 is fixed to the body 8 through the fixing block 2, and a piezoelectric element 6 is fixed to the upper and lower sides of the leaf spring 5, respectively. The other end of the leaf spring 5 is fixed with a silicone pad 7.

[0038] The main body of this invention has an air cavity inside, which consists of a main cavity and a conical cavity. The main cavity is connected to the smaller end of the conical cavity, and the other end of the main cavity is connected to an air inlet connector 10. The middle part of the air cavity is connected to an air outlet connector 9. The air outlet connector is connected to the main cavity at a certain angle.

[0039] The silicone pad vibrates up and down under the action of the leaf spring, thereby opening or closing the conical cavity.

[0040] The air outlet of the electrically controlled pneumatic valve of the present invention forms a conical cavity structure between the air outlet and the piezoelectric valve, that is, a conical cavity is provided in the air cavity, and the air supply pipeline and the air discharge pipeline for separation form an acute angle structure.

[0041] The present invention utilizes a conical cavity structure to form an air pressure circuit. When the valve is open, compressed air can be discharged more effectively to the outside of the valve. When the valve is closed, the acute angle structure between the air supply pipeline and the separation air discharge pipeline allows compressed air to enter the separation discharge pipeline more smoothly, making it easier to generate a vacuum and form an air pressure disruption state, so that the subsequent separation of small components is not affected.

[0042] like Figure 12 and 13 As shown, when the valve is closed, the conical cavity structure and the acute angle structure between the air supply pipeline and the separation air discharge pipeline allow compressed air to enter the separation discharge pipeline more smoothly, which can quickly convert the vacuum state into the pneumatic state and deliver the compressed air to the component separation point more effectively.

[0043] like Figure 10 , 11 As shown, this invention also discloses a high-speed micro-component electronically controlled air compressor valve selection device, which includes the aforementioned electronically controlled air compressor valve, as well as a linear vibration track 22 and an optical sensor 23. The linear vibration track is existing technology. Compressed air flows out from the air outlet connector 25 and enters the linear vibration track. The diameter of the air passage 26 on the linear vibration track decreases. The component to be selected 24 is placed at the outlet of the air passage 26 on the linear vibration track. The component is selected and identified by the optical sensor 23, and components 24 that do not meet the requirements are selected out.

[0044] When the sensor detects a defective part, the air valve must immediately release air to remove it. After the defective part is removed and the sensor detection is complete, the air valve must immediately stop releasing air. The air inside the air valve must flow in a specific direction without resistance. The air valve must immediately start and stop air release in response to the sensor's detection signal. When air release stops, the area from the air valve to the selective discharge port should be close to a vacuum (S direction described below).

[0045] like Figure 2 As shown, in existing technologies, when airflow exits through a narrow passage, it typically diffuses outward in a fan shape. In existing structures, the airflow encounters resistance (walls) during its flow, preventing it from forming a straight flow up to the exhaust port and creating trapped air. Therefore, some trapped air is delivered in the S-direction, reducing the vacuum effect and impacting the selection of good products. When the vacuum effect decreases, the complete start-stop time of the compressed air naturally increases. For example... Figure 14 , 15 As shown, in the structure of the present invention, since the air diffusion direction inside the air pressure valve does not easily form resistance with the conical cavity structure and the acute angle structure of the air supply pipe and discharge pipe of the present proposal, when the air is stopped from being discharged (when the valve is open), the air in the S direction is pulled by the compressed air discharge port direction, and an approximate vacuum state is formed immediately.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
