Description

Technical Field

[0001] The invention relates to the field of valve nozzle assembly detection, and more specifically to a valve nozzle full-automatic intelligent assembly detection device. Background Art

[0002] The valve is an independent valve body device, which is mainly used to inflate or release gas or liquid into the tire, and maintain and detect the internal pressure, playing the role of a one-way valve (check valve). The valve is usually composed of the valve body, sealing gasket, liner, fastening nut, valve core, and valve cap. These parts play their respective roles in the structure of the valve, and together ensure the normal operation and safety of the valve.

[0003] When assembling the valve, some riveting devices are usually used to press the above components together. For example, a valve assembly system disclosed in a Chinese patent, the invention patent with publication number CN107100919B, is disclosed in the public document. The gasket is partially melted by the high-speed rotation of the riveting head and is bonded and pressed with the valve core shell. The whole process is fully automated. However, after the valve is assembled, it is necessary to detect the air tightness of the valve and whether it can perform normal ventilation work to determine whether the assembled valve meets the production standards. The following technical means are used to detect the air tightness of the valve in the prior art:

[0004] For example, the invention patent with publication number CN110296797A, the patent for an airtight test mechanism, the Chinese utility model patent with publication number CN212963872U, and the patent for a valve leakage detection device. Both of the above sets of documents are to install the valve on a sealed cavity, fill the sealed cavity with high-pressure gas, and then sink the valve and the sealed cavity into water to observe whether bubbles are generated. If bubbles are generated, the sealing effect of the valve is not good. If no bubbles are generated, the valve is a qualified product. This detection method also requires the valve to be dried in the later stage, which increases the process steps and has certain limitations.

[0005] For example, the invention patent with publication number CN108303223A is a patent for a valve leakage detection device. This patent abandons the method of judging whether the valve is qualified by observing bubbles, but instead uses an air pressure gauge to detect whether there is a leak, thereby avoiding contact between the valve and water.

[0006] The valve nozzle detection equipment in the prior art still has some shortcomings in practical applications. For example, when the valve nozzle is placed, if the connection between the valve nozzle and the valve nozzle opening installed on the detection equipment is not sealed well, gas leakage will occur during detection. The leaked gas makes it impossible to maintain the air pressure inside the detection equipment at a preset stable state, thereby causing deviation and inaccuracy in the detection data.

[0007] In view of this, in order to address the above-mentioned deficiencies, the present invention improves and optimizes the valve nozzle detection equipment in the prior art and develops a fully automatic intelligent assembly detection device for the valve nozzle. Summary of the invention

The pressing ring can also straighten the tilted valve nozzle when pressing the gasket, ensuring that the valve nozzle can be well inserted into the inflation head, thereby ensuring stable inflation work.

[0082] A pressure stabilizing component is arranged above the first annular airbag cushion 7. The pressure stabilizing component is used to stably press the valve. The pressure stabilizing component includes: a pressing ring 19. A first cylinder 16 is installed on the mounting plate 4. The upper end of the first cylinder 16 is connected to the pressing ring 19. The first cylinder 16 pulls the pressing ring 19 downward so that the pressing ring 19 stably presses the gasket of the valve; a limiting plate 12. The limiting plate 12 is installed on the upper surface of the mounting plate 4; an inclined groove 14. The inclined groove 14 is opened on the side surface of the mounting plate 4; a lower vertical groove 15. The lower vertical groove 15 is opened on the side surface of the mounting plate 4 and is located below the inclined groove 14. The lower vertical groove 15 is connected with the inclined groove 14; the horizontal plate 18, one end of which is fixedly connected with the pressing ring 19; the slider rod 20, which is installed on the side of the horizontal plate 18, and the end of the slider rod 20 away from the horizontal plate 18 is arranged in the inclined groove 14, and the slider rod 20 can slide up and down in the inclined groove 14 and the lower vertical groove 15; the slide groove 21, which is opened at the lower surface of the horizontal plate 18; the slider 17, which is slidably arranged in the slide groove 21, and the lower end of the slider 17 is fixedly connected with the first cylinder 16; the slider 17 is designed as a trapezoidal or T-shaped structure, and the outer surface of the slider 17 is arranged to coincide with the inner wall of the slide groove 21;

[0083] An inflation component, which is arranged above the pressure stabilizing component, and is used to inflate the valve mouth after stable pressing. The inflation component includes a support rod 23, and the support rod 23 is installed on the right side of the mounting seat 1; a fourth cylinder 26, and the fourth cylinder 26 is installed at the end of the support rod 23 away from the mounting seat 1; an inflation head 25, and the inflation head 25 is installed at the lower end of the fourth cylinder 26; an air guide tube 24, and one end of the air guide tube 24 is connected to the inflation head 25, and the end of the air guide tube 24 away from the inflation head 25 is connected to an external inflation pump.

[0084] The assembled valve mouth is automatically loaded into the device of the present invention by a manipulator or some other loading equipment. The loading is carried out from the front end of the present invention. The valve mouth is inserted into a first annular airbag cushion 7 at the front end of the present invention, and the inflation port of the valve mouth faces upward. The gasket 41 on the valve mouth will press on the first annular airbag cushion 7, and then the motor 2 drives the rotating disk 3 to rotate counterclockwise by 90°, and the next group of unloaded mounting plates 4 will rotate to the loading position, and then continue to load; when the mounting plate 4 rotates with the rotating disk 3, the first cylinder 16 will contract and pull the slider 17 downward, and the slider 1 7 drives the horizontal plate 18 to move downward, and the horizontal plate 18 will drive the slider rod 20 to move downward synchronously during the downward movement. The initial position of the slider rod 20 is at the upper end of the inclined groove 14. During the downward movement, the slider rod 20 will follow the inclined groove 14 and move from the inclined groove 14 to the lower vertical groove 15. At this time, the horizontal plate 18 and the pressing ring 19 will also move downward obliquely. Finally, the pressing ring 19 is located directly above the valve mouth. As the first cylinder 16 continues to pull, the slider rod 20 will move downward along the lower vertical groove 15, and finally the pressing ring 19 moves downward. The gasket 41 is moved and pressed tightly on the gasket 41, so that the gasket 41 is pressed tightly on the first annular airbag cushion 7, so that the two are in close contact, avoiding the problem of the valve mouth being skewed. After the mounting plate 4 is deflected 90 degrees, the inflation port of the valve mouth will be just below the inflation head 25, and then the fourth cylinder 26 pushes the inflation head 25 to move downward, and the inflation port of the valve mouth will enter the inflation head 25, and then the external inflation pump is used to supply air to the air guide pipe 24, and the gas in the air guide pipe 24 will enter the inflation head 25, enter the valve mouth from the inflation head 25, and enter the valve mouth from the valve mouth. Into the air measuring cylinder 5 below, a controller is installed in the mounting base 1, and when the air pressure sensor 6 detects that the air pressure in the air measuring cylinder 5 has reached a preset air pressure value, the controller controls the inflation pump to stop supplying air. Some valve mouths cannot be ventilated due to damage caused during assembly, or the ventilation is not smooth. When the inflation pump reaches the preset air supply time value, and the air pressure sensor 6 does not detect that the air pressure in the air measuring cylinder 5 has reached the preset air pressure value, the controller will still control the inflation pump to stop supplying air, and the fourth cylinder 26 contracts to control the inflation head 25 to return to the initial position. At this time, the valve mouth detected is a valve mouth that cannot ventilate normally.

[0085] The inflated valve continues to rotate with the mounting plate 4, and rotates 180° counterclockwise with the mounting plate 4. If the air pressure value in the air measuring cylinder 5 drops to a preset value during the rotation, the valve is a leaking valve. If the air pressure value in the air measuring cylinder 5 is within the preset value during the rotation, the valve is a qualified valve.

[0086] In some embodiments, it includes an upper vertical groove 13, which is provided on the side surface of the limiting plate 12 and is located above the inclined groove 14, and the upper vertical groove 13 and the inclined groove 14 are connected to each other; a fixing plate 11, which is fixedly installed on the upper surface of the mounting plate 4; a tough film 10, one end of the tough film 10 is fixedly connected to the fixing plate 11; a folding plate 8, which is arranged below the first annular airbag cushion 7, the folding plate 8 is fixedly connected to the first annular airbag cushion 7, and a hole for plugging the valve is provided on the folding plate 8 at the center of the first annular airbag cushion 7; a traction rope 22, one end of the traction rope 22 is fixedly connected to the folding plate 8, and the other end of the traction rope 22 is fixedly connected to the pressing ring 19;

[0087] The material distribution pipe 32 is arranged at the left side of the mounting seat 1, and the material distribution pipe 32 is fixedly connected to the mounting seat 1 through a support plate, and the material distribution pipe 32 is arranged at an angle; the material outlet 39 is arranged in three groups, and multiple groups of material outlets 39 are evenly opened at the lower position of the material distribution pipe 32; the first sealing plate 35 is slidably arranged at the rightmost group of material outlets 39; the first connecting rod 34, the lower end of the first connecting rod 34 is fixed to the first sealing plate 35 Fixed connection; a second cylinder 33, the second cylinder 33 is installed at the upper end of the distribution pipe 32, and the output end of the second cylinder 33 is fixedly connected to the first connecting rod 34; a second sealing plate 38, the second sealing plate 38 is slidably arranged at the discharge port 39 of the middle group; a second connecting rod 37, the lower end of the second connecting rod 37 is fixedly connected to the second sealing plate 38; a third cylinder 36, the third cylinder 36 is installed at the upper end of the distribution pipe 32, and the output end of the third cylinder 36 is fixedly connected to the second connecting rod 37.

[0088] After the valve is rotated to 270° from the loading position, it will come to the distribution pipe 32. At this time, the first cylinder 16 will push the slider 17 upward, thereby pushing the cross plate 18 to move upward, and the slider rod 20 will slide from the lower vertical groove 15 to the inclined groove 14, and then slide from the inclined groove 14 to the upper vertical groove 13. At this time, the cross plate 18 and the pressing ring 19 will pull the folding plate 8 through the traction rope 22 during the upward movement. The end of the folding plate 8 away from the fixing plate 11 is pulled up, and at this time, the valve on the first annular airbag cushion 7 is also in an inclined state, and falls from the first annular airbag cushion 7, rolling along the folding plate 8 and rolling into the distribution pipe 32;

[0089] If the air valve in the material distribution pipe 32 is poorly ventilated or cannot be ventilated at this time, the second cylinder 33 pushes the first connecting rod 34 to move, and the first connecting rod 34 drives the first sealing plate 35 to open the corresponding discharge port 39 during the movement. When the air valve rolls along the inner wall of the material distribution pipe 32, it will fall from the discharge port 39 corresponding to the first sealing plate 35;

[0090] If the valve in the material distribution pipe 32 is leaking, the third cylinder 36 pushes the second connecting rod 37 to move, and the second connecting rod 37 drives the second sealing plate 38 to open the corresponding discharge port 39 during the movement. When the valve rolls along the inner wall of the material distribution pipe 32, it will fall from the discharge port 39 of the corresponding second sealing plate 38.

[0091] If the valve in the distribution pipe 32 is a qualified valve, the first sealing plate 35 and the second sealing plate 38 do not move, and the valve will roll to the leftmost end of the distribution pipe 32 and fall from the leftmost group of discharge ports 39. Different collection frames can be placed under the three groups of discharge ports 39 to automatically collect valves of different standards.

[0092] After the feeding into the distribution pipe 32 is completed, the mounting plate 4 rotates toward the upper feeding position. During the rotation, the first cylinder 16 pulls the slider 17 downward to return the transverse plate 18 and the pressing ring 19 to their initial positions.

[0093] In some embodiments, a second annular airbag cushion 9 is included. The second annular airbag cushion 9 is fixedly installed below the folding plate 8 , and the second annular airbag cushion 9 is vertically corresponding to the first annular airbag cushion 7 .

[0094] By installing the second annular airbag cushion 9, when the pressing ring 19 presses the gasket 41, the second annular airbag cushion 9 will be squeezed through the folding plate 8, thereby ensuring the sealing between the folding plate 8 and the mounting plate 4, and preventing the gas in the gas measuring cylinder 5 from leaking from between the folding plate 8 and the mounting plate 4.

[0095] In some embodiments, a flexible strip 40 is included, and the flexible strip 40 is arranged in multiple groups. The flexible strip 40 is fixedly installed on the inner wall of the upper end of the distribution tube 32. The flexible strip 40 is arranged close to the right end of the distribution tube 32. The flexible strip 40 is made of flexible rubber or cloth material.

[0096] When the folding plate 8 is pulled up to drop the valve into the distribution tube 32, if the valve falls into the distribution tube 32 instead of sliding into the distribution tube 32, the valve will hit the inner wall of the distribution tube 32 and bounce inside the distribution tube 32, which can easily jump over the corresponding discharge port 39. For this reason, the present invention installs a flexible strip 40 in the distribution tube 32. When the valve jumps in the distribution tube 32, it will hit the flexible strip 40. The flexible strip 40 releases force, so that the valve cannot jump and can only roll downward along the inner wall of the distribution tube 32.

[0097] In some embodiments, the trigger rods 28 are provided in multiple groups, and the number of the trigger rods 28 corresponds to the number of the mounting plates 4, and the trigger rods 28 are evenly fixedly installed on the lower surface of the rotating disk 3; an annular groove 27, which is provided on the upper surface of the mounting seat 1 and corresponds to the position of the trigger rod 28, and the trigger rod 28 can rotate along the annular groove 27; a groove 29, which is provided at the inner bottom position of the annular groove 27; a first conductive sheet 30, which is provided in the groove 29, and one end of the first conductive sheet 30 is fixedly connected to the inner wall of the groove 29; a second conductive sheet 31, which is made of elastic material, which is provided at the upper position of the first conductive sheet 30, one end of the second conductive sheet 31 extends into the annular groove 27, and the other end of the second conductive sheet 31 is fixedly connected to the inner wall of the groove 29; a controller, which is installed in the mounting seat 1, and the first conductive sheet 30 and the second conductive sheet 31 are electrically connected to the controller, and the controller is used to control the rotation amplitude of the motor 2.

[0098] When the rotating disk 3 rotates, it will drive the trigger rod 28 below to rotate synchronously. Every time the rotating disk 3 rotates 90°, the corresponding trigger rod 28 will move to the second conductive sheet 31. At this time, the trigger rod 28 squeezes the second conductive sheet 31, and finally makes the second conductive sheet 31 contact with the first conductive sheet 30, and the circuit is closed. The controller receives the electrical signal of the circuit closure and controls the motor 2 to stop rotating. After a period of time, the controller controls the motor 2 to rotate, and the corresponding trigger rod 28 squeezes the second conductive sheet 31 again. The controller receives the electrical signal of the circuit closure and controls the motor 2 to stop rotating again. In this way, the motor 2 can be controlled to accurately deflect 90° each time, avoiding the problem of inaccurate deflection of the motor 2 due to loss of step.

[0099] Working principle: First, insert the valve into the first annular airbag cushion 7 of the front end of the present invention, with the inflation port of the valve facing upward, the gasket 41 on the valve will press on the first annular airbag cushion 7, and then the motor 2 drives the rotating disk 3 to rotate 90° counterclockwise, and the next group of unloaded mounting plates 4 will rotate to the loading position, and then continue loading; when the mounting plate 4 rotates with the rotating disk 3, the first cylinder 16 will contract and pull the slider 17 downward, and the slider 17 will drive the cross plate 18 to move downward, and the cross plate 18 will drive the slider rod in the process of moving downward. The slider rod 20 moves downward synchronously, the initial position of the slider rod 20 is at the upper end of the inclined groove 14, and the slider rod 20 moves along the inclined groove 14 and moves from the inclined groove 14 to the lower vertical groove 15 during the downward movement, and at this time, the cross plate 18 and the pressing ring 19 also move downward obliquely, and finally the pressing ring 19 is located directly above the valve mouth. As the first cylinder 16 continues to pull, the slider rod 20 moves downward along the lower vertical groove 15, and finally the pressing ring 19 moves downward and presses tightly on the gasket 41, so that the gasket 41 is tightly pressed. The air inlet of the air valve mouth is pressed on the first annular airbag cushion 7 so that the two are in close contact, thereby avoiding the problem of the valve mouth being skewed. After the mounting plate 4 is deflected 90°, the air inlet of the valve mouth will be just below the air inlet head 25, and then the fourth air cylinder 26 pushes the air inlet head 25 to move downward, and the air inlet of the valve mouth will enter the air inlet head 25, and then the air is supplied to the air guide pipe 24 through the external air pump. The gas in the air guide pipe 24 will enter the air inlet head 25, enter the valve mouth from the air inlet head 25, and enter the air measuring cylinder 5 below from the valve mouth, and then enter the air inlet of the air inlet head 25. A controller is installed in the mounting seat 1. When the air pressure sensor 6 detects that the air pressure in the air measuring cylinder 5 has reached a preset air pressure value, the controller controls the air pump to stop supplying air. Some valve nozzles cannot be ventilated or the ventilation is not smooth due to damage caused during assembly. When the air pump reaches the preset air supply time value, but the air pressure sensor 6 does not detect that the air pressure in the air measuring cylinder 5 has reached the preset air pressure value, the controller will still control the air pump to stop supplying air. The fourth cylinder 26 contracts to control the inflation head 25 to return to the initial position. At this time, the valve nozzle detected is a valve nozzle that cannot ventilate normally.

[0100] The inflated valve continues to rotate with the mounting plate 4, and rotates 180° counterclockwise with the mounting plate 4. If the air pressure value in the air measuring cylinder 5 drops to a preset value during the rotation, the valve is a leaking valve. If the air pressure value in the air measuring cylinder 5 is within the preset value during the rotation, the valve is a qualified valve.

[0101] When the valve rotates to the distribution pipe 32 along with the mounting plate 4, the first cylinder 16 will push the slider 17 upward, thereby pushing the cross plate 18 to move upward, and the slider rod 20 will slide from the lower vertical groove 15 to the inclined groove 14, and then slide from the inclined groove 14 to the upper vertical groove 13. At this time, the cross plate 18 and the pressing ring 19 will pull the folding plate 8 through the traction rope 22 during the upward movement, and the end of the folding plate 8 away from the fixing plate 11 will be pulled up, and at this time, the valve on the first annular airbag cushion 7 is also in an inclined state, and falls from the first annular airbag cushion 7, rolling along the folding plate 8 and rolling into the distribution pipe 32;

[0102] If the air valve in the material distribution pipe 32 is poorly ventilated or cannot be ventilated at this time, the second cylinder 33 pushes the first connecting rod 34 to move, and the first connecting rod 34 drives the first sealing plate 35 to open the corresponding discharge port 39 during the movement. When the air valve rolls along the inner wall of the material distribution pipe 32, it will fall from the discharge port 39 corresponding to the first sealing plate 35;

[0103] If the valve in the material distribution pipe 32 is leaking, the third cylinder 36 pushes the second connecting rod 37 to move, and the second connecting rod 37 drives the second sealing plate 38 to open the corresponding discharge port 39 during the movement. When the valve rolls along the inner wall of the material distribution pipe 32, it will fall from the discharge port 39 of the corresponding second sealing plate 38.

[0104] If the valve in the distribution pipe 32 is a qualified valve, the first sealing plate 35 and the second sealing plate 38 do not move, and the valve will roll to the leftmost end of the distribution pipe 32 and fall from the leftmost group of discharge ports 39. Different collection frames can be placed under the three groups of discharge ports 39 to automatically collect valves of different standards.

[0105] The above are only preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
