Description

Technical Field

[0001] The invention belongs to the technical field of solenoid valve production, and in particular relates to a plug screening machine. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions in the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed regulating valves, etc.

[0003] Micro valve bodies usually refer to valve components with small size and compact structure, which are suitable for occasions that require precise control and space saving. Micro valve bodies are widely used in various microfluidic systems, medical equipment, analytical instruments, semiconductor manufacturing and other fields. Their materials, design and manufacturing processes must meet the requirements of high precision, high reliability and long life.

[0004] A plug is a component used to close a hole in a pipe or equipment that does not require fluid to pass through. In the application of solenoid valves and micro valve bodies, plugs are usually used to block unnecessary ports or prevent fluid leakage. The material, size and shape of the plug will vary according to the specific application scenario. Common materials include metal, plastic and rubber. In the process of valve body assembly, it is necessary to ensure that the size of the plug matches the port size of the solenoid valve or micro valve body to ensure a good sealing effect. In the current existing valve body assembly, the plug is usually inspected by random inspection. If the size of the plugs sampled is within the qualified standard range, the batch is deemed qualified. Although this method is efficient, there will be errors in the thickness of the plug and the size of the valve body port. If the upper limit and the lower limit are assembled together, the sealing effect will inevitably be poor. Therefore, if each plug can be inspected, the thickness of the plug can be vertically graded within the qualified standard range, and assembled with the corresponding matching valve body port size, the sealing of each assembled valve body can be guaranteed to be good. Summary of the invention

[0005] The purpose of the present invention is to provide a plug screening machine to solve the above-mentioned technical problems, so as to achieve the effect of improving the sealing performance of the valve body after assembly.

[0006] In view of this, the present invention provides a plug screening machine, comprising:

[0007] A vibration plate, the vibration plate is used to accommodate the plugs, and the vibration plate vibrates to arrange and load the plugs;

[0008] A turntable, the turntable is used to receive the plugs fed from the vibrating plate, and the turntable can intermittently rotate around the axis of the turntable with the plugs;

[0009] A thickness detector, which is arranged on the side of the turntable and is used to detect the thickness of the plug on the turntable;

[0010] A material receiving assembly, which is arranged below the turntable and is used to receive plugs of different thicknesses that fall from the turntable;

[0011] A pushing assembly is provided in plurality along the circumferential direction of the turntable, and the pushing assembly can push plugs of different thicknesses into different positions of the receiving assembly for classification and collection.

[0012] In the present technical solution, the plugs are arranged and loaded onto the turntable through the vibration of the vibrating disk. The turntable rotates and drives the plugs to rotate circumferentially around the axis of the turntable. When the plugs are rotated to the thickness detector, the thickness detector detects the thickness of the plugs. According to the results of the thickness detection, different pushing components are controlled to push the plugs into different positions of the receiving components, so that plugs of different thicknesses can be classified and collected, which is convenient for matching and assembly with the classified valve bodies, so as to improve the sealing of the valve body after assembly.

[0013] Furthermore, the turntable comprises:

[0014] A rotating disk, the rotating disk can rotate in a circumferential direction, and a plurality of notches are provided on the rotating disk along the circumferential direction, and the notches are used to accommodate the plugs;

[0015] The fixed disk is fixedly arranged below the rotating disk, and the outer edge of the fixed disk is larger than the rotating disk and can be received below the notch.

[0016] Furthermore, a feed port is provided on the fixed plate below each notch, and a feed port rotating cover is provided with a feed port plate. Under the action of a torsion spring, the feed port plate always has a movement tendency to press the cover on the feed port. A pushing assembly is provided corresponding to each feed port, and the pushing assembly is used to push the feed plate to rotate away from the feed port so that the plug falls into the receiving assembly from the notch and the feed port.

[0017] Further, the pusher assembly is fixedly arranged on a disc seat, the disc seat ring is arranged on the outer periphery of the turntable, and the pusher assembly includes:

[0018] A fixing plate, the fixing plate being fixedly arranged on the disc seat;

[0019] The push cylinder is fixedly arranged on the fixed plate, and the piston rod of the push cylinder points to the unloading plate.

[0020] Furthermore, each push cylinder is connected to an air supply pipe, and a receiving hole for receiving the air supply pipe is provided on the disc seat corresponding to each push cylinder. The air supply pipe extends from the side of the thickness detector and is connected to the air pump.

[0023] The material receiving drawer is slidably arranged in a fixed frame, a circular ring is fixedly arranged in the material receiving drawer, a collecting box is arranged on the circular ring corresponding to each material discharge port, and the collecting box is detachably connected to the circular ring.

[0024] In the present technical solution, after the thickness detector measures the thickness of the plug, it determines which gear position the thickness value of the plug is in, and it should be carried out at the corresponding discharge port. Then, when the plug is rotated to the corresponding discharge port with the turntable, the piston rod of the pushing cylinder of the pushing assembly at that place extends to push the discharge plate to rotate away from the discharge port. The plug then falls from the notch and the discharge port, and slides under the guidance of the inclined discharge plate into the collection box on the receiving assembly corresponding to the discharge port. When the collection box is almost full, pull out the receiving drawer, take out the collection box, empty it, put the collection box back and continue screening. The recycling operation of the receiving assembly is simple and convenient.

[0025] Furthermore, the pushing assembly and the feeding port are each provided with eight and are arranged on the side of the turntable away from the feeding.

[0026] Furthermore, a guide plate is provided between the vibration disk and the rotating disk, and the guide plate extends obliquely downward from the vibration disk to the rotating disk, and a slideway allowing the plug to move is provided in the guide plate.

[0027] Furthermore, a handle is provided on the outside of the material receiving drawer.

[0028] Furthermore, the plug screening machine is also provided with a control screen for inputting a numerical range of plug thickness classification.

[0029] The beneficial effects of the present invention are:

[0030] 1. The plugs are arranged and loaded onto the turntable through the vibration of the vibrating plate. The turntable rotates with the plugs to rotate circumferentially around the axis of the turntable. When the plugs are turned to the thickness detector, the thickness detector detects the thickness of the plugs. According to the results of the thickness detection, different pushing components are controlled to push the plugs into different positions of the receiving components, so that plugs of different thicknesses can be classified and collected, which is convenient for matching and assembly with the classified valve bodies, so as to improve the sealing of the valve body after assembly.

[0031] 2. After the thickness detector measures the thickness of the plug, it determines which gear the thickness value of the plug is in, and it should be placed at the corresponding discharge port. When the plug is rotated to the corresponding discharge port with the turntable, the piston rod of the pushing cylinder of the pushing assembly at that location extends, pushing the discharge plate to rotate away from the discharge port. The plug then falls from the notch and the discharge port, and slides under the guidance of the inclined discharge plate into the collection box corresponding to the discharge port on the receiving assembly. When the collection box is almost full, pull out the receiving drawer, take out the collection box, empty it, put the collection box back and continue screening. The recycling operation of the receiving assembly is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
