They are actuators and are not limited to hydraulic and 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 of the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed control valves, etc. After the solenoid valves are produced and processed, the various performances of the solenoid valves are usually tested.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The plurality of industrial cameras 11 are all area array industrial cameras of the prior art with the model of Dahua A7900CU201.

[0032] As a technical optimization solution of the present invention, two first chutes 4 are provided on the top of the bottom plate 1, and first sliders 5 are installed inside the two first chutes 4, and the top ends of the two first sliders 5 are connected to the top plate 3 through first electric telescopic rods 6. First linear motors are preset inside the two first chutes 4, and the two first linear motors can drive the two first sliders 5 to move back and forth inside the corresponding first chutes 4, and drive the two first electric telescopic rods 6 and the top plate 3 to move back and forth on the top of the bottom plate 1 synchronously.

[0033] As a technical optimization solution of the present invention, the clamping mechanism includes a groove 18 opened inside the rotating plate 7, a double-headed screw 16 is rotatably installed inside the groove 18, two moving seats 19 are threadedly installed on the outer wall of the double-headed screw 16, and two second electric telescopic rods 20 are installed on the top of the two moving seats 19. A first driving device is preset inside the rotating plate 7, and the output end of the first driving device is connected to one end of the double-headed screw 16, which can drive the double-headed screw 16 to rotate inside the groove 18, and drive the two moving seats 19 to move towards or away from each other.

[0034] As a technical optimization solution of the present invention, the telescopic ends of the two second electric telescopic rods 20 are jointly installed with a mounting frame 21, the bottom ends of the two mounting frames 21 are both installed with a first motor 22, the output ends of the two first motors 22 are both installed with a clamping plate 12, and the insides of the two clamping plates 12 are both installed with an electric heating plate 23. During the telescopic process, the telescopic ends of the two second electric telescopic rods 20 can drive the mounting frame 21, the first motor 22 and the clamping plate 12 to move up and down together; the two first motors 22 can drive the two clamping plates 12 to rotate and adjust.

[0035] As a technical optimization solution of the present invention, a rotating block 24 is rotatably installed on the top of the two mounting frames 21, and multiple nozzles 25 are installed on the outer wall of the side where the two rotating blocks 24 are close to each other. A second driving device is preset on the outer wall of one side of the two mounting frames 21, and the output ends of the two second driving devices are respectively connected to the rotating parts of the rotating blocks 24, which can drive the two rotating blocks 24 to rotate and adjust on the top of the corresponding mounting frames 21; because the two rotating blocks 24 are both hollow and connected to the external preset water outlet device through the connecting pipe, the multiple nozzles 25 can spray water mist outward to the surface of the valve body 8 to perform a waterproof mist test.

[0036] As a technical optimization solution of the present invention, the driving mechanism includes a second motor 13 installed on the outer wall of one side of the fixed block 2, and a cavity is opened inside the fixed block 2. The output end of the second motor 13 extends through the fixed block 2 to the cavity and is connected to an elliptical driving block 17, and the outer wall of the driving block 17 abuts against the bottom end of the rotating plate 7. After starting, the second motor 13 can drive the driving block 17 to rotate in the cavity. Since the driving block 17 is elliptical, it can continuously push the bottom end of the rotating plate 7 during the rotation process, driving the rotating plate 7 to continuously shake up and down; and an electromagnet is preset inside the fixed block 2, and the outer wall of one side of the electromagnet abuts against the rotating plate 7, so that the electromagnet is magnetically fixed to the rotating plate 7 after power is turned on, and has a limiting effect on the rotating plate 7, so as to prevent the rotating plate 7 from shaking when it is not driven by the driving block 17 inside the fixed block 2, which affects the use of the rotating plate 7.

[0037] As a technical optimization solution of the present invention, the cleaning mechanism includes two second chutes 26 opened at the top of the two fixed plates 9, and the second sliders 27 are installed inside the two second chutes 26, and the tops of the two second sliders 27 are installed with the movable plate 14. The second linear motors are preset inside the two second chutes 26, and the two second linear motors can drive the two second sliders 27 to move back and forth inside the corresponding second chutes 26, and drive the two movable plates 14 to move back and forth on the tops of the corresponding fixed plates 9 for adjustment.

[0038] As a technical optimization solution of the present invention, the interior of the two movable plates 14 is installed with fixed rods 28 corresponding to the number of valve holes 10, and the ends of the multiple fixed rods 28 close to the valve holes 10 are provided with threaded parts 32, and the outer walls of the multiple threaded parts 32 are threadedly installed with rubber dust sticking blocks 30. When the two movable plates 14 move toward the direction close to the valve body 8, the ends of the multiple fixed rods 28 close to the valve body 8 are driven to be inserted into the corresponding valve holes 10, so that after the multiple rubber dust sticking blocks 30 enter the corresponding valve holes 10, the impurities inside the valve holes 10 adhered to the surface of the rubber dust sticking blocks 30 are cleaned and removed.

[0039] As a technical optimization solution of the present invention, the outer wall of one end of the multiple fixing rods 28 close to the threaded portion 32 is equipped with an air bag 31, and the multiple air bags 31 are connected to an external preset inflation mechanism through a hose. After the ends of the multiple fixing rods 28 close to the valve body 8 are inserted into the corresponding valve holes 10, the air bags 31 are controlled to inflate and block the valve holes 10.

[0040] As a technical optimization solution of the present invention, the interiors of the plurality of fixing rods 28 are all hollow, and the ends of the plurality of fixing rods 28 away from the valve hole 10 are all provided with connecting ends 29, and the plurality of connecting ends 29 are all connected to the pipes 15. In actual use, the length of the pipe 15 in this embodiment is much longer than the length shown in the drawings, and the other end of the pipe 15 can be connected to an external preset gas delivery device or water delivery device, that is, gas or liquid can be delivered to the interior of the valve body 8, and the sealing performance of the valve body 8 can be tested.

[0041] In the present invention, when the user uses the device, the two first sliders 5 are controlled to move in the corresponding first slide grooves 4, driving the top plate 3 to move and adjust in the direction away from the fixed block 2, and then the valve body 8 can be placed on the top of the rotating plate 7, and the double-headed screw 16 is controlled to rotate, driving the two moving seats 19 to move in the direction of approaching each other, and driving the two clamping plates 12 to move in the direction of approaching each other, clamping and fixing the two ends of the valve body 8 placed on the top of the rotating plate 7, and finally controlling the two first sliders 5 to slide and reset inside the corresponding first slide grooves 4, driving the top plate 3 to move to the top of the fixed block 2, waiting for the subsequent performance test of the valve body 8.

[0042] Before performing relevant performance tests on the valve body 8, the telescopic ends of the multiple second electric telescopic rods 20 can be controlled to extend upward together, pushing the two clamping plates 12 and the clamped valve body 8 to move upward together, and at the same time, the telescopic ends of the two first electric telescopic rods 6 can be controlled to extend upward, pushing the top plate 3 to move upward together, until the top plate 3 and the two clamping plates 12 move upward to a suitable height together, ensuring that the multiple industrial cameras 11 at the bottom of the top plate 3 can clearly identify the surface of the valve body 8 below, and then control the two first motors 22 to start together, driving the two clamping plates 12 and the clamped valve body 8 to rotate slowly together, so that the multiple industrial cameras 11 can identify and detect the appearance of the valve body 8 and the multiple valve holes 10, ensuring that there is no problem with the quality of the valve body 8 itself undergoing relevant performance tests, which is conducive to the subsequent relevant performance tests of the valve body 8.

[0043] After the appearance quality of the valve body 8 is inspected by means of multiple industrial cameras 11, the telescopic ends of the multiple second electric telescopic rods 20 are controlled to retract downward and return to their original positions, driving the valve body 8 to fall downward and be placed on the top of the rotating plate 7. At this time, the positions of the multiple valve holes 10 on both sides of the valve body 8 correspond to the positions of the multiple fixed rods 28 arranged inside the two movable plates 14. The multiple second sliders 27 can be controlled to move in the direction close to the fixed block 2 inside the corresponding second slide grooves 26, and the ends of the multiple fixed rods 28 close to the valve body 8 can be driven to be slowly inserted into the corresponding valve holes 10. With the help of the rubber dust sticking blocks 30 arranged at one end of the multiple fixed rods 28 close to the valve body 8, the impurities and dust attached to the inside of the multiple valve holes 10 can be automatically treated with dust sticking. Then, the multiple second sliders 27 are controlled to move in the direction away from the fixed block 2 inside the corresponding second slide grooves 26, driving the multiple rubber dust sticking blocks 30 to move out from the inside of the corresponding valve holes 10, so as to achieve the effect of automatically cleaning the inside of the multiple valve holes 10, and avoid the problem that the impurities and dust inside the valve holes 10 have an adverse effect on the subsequent related performance tests.

[0044] After the rubber dust sticking blocks 30 are removed from the corresponding valve holes 10, if it is found that there is a lot of dirt attached to the surface of the rubber dust sticking blocks 30, they can be directly unscrewed from the surface of the threaded portion 32 to be removed, and when the valve hole 10 of the next valve body 8 is cleaned, a new rubber dust sticking block 30 can be installed;

[0045] After cleaning the multiple valve holes 10 of the valve body 8, the multiple connecting ends 29 can be connected to one end of the pipeline 15, and the other end of the multiple pipelines 15 can be connected to an external preset gas transmission device or water transmission device, and the multiple second sliders 27 are controlled to move in the direction close to the fixed block 2 inside the corresponding second slide groove 26, so that the two movable plates 14 drive the multiple fixed rods 28 to insert one end close to the valve body 8 into the corresponding valve hole 10 again, and drive the air bags 31 arranged on the outer wall of the multiple fixed rods 28 to enter the valve hole 10 together, control the multiple air bags 31 to inflate in the corresponding valve hole 10, and block the gap between the multiple valve holes 10 and the fixed rods 28, so that the gas or liquid transported by the multiple pipelines 15 can enter the interior of the valve body 8 through the multiple valve holes 10, simulate the use of the valve body 8 for opening and closing the gas or liquid transportation during actual use, and perform a sealing test on the valve body 8. At this time, the multiple industrial cameras 11 located at the bottom of the top plate 3 can record the test situation in real time to determine whether the sealing test of the valve body 8 is qualified.

[0046] After the sealing test of the valve body 8 is completed, the external preset water outlet equipment can be controlled to start, so that the multiple nozzles 25 can spray water mist toward the surface of the valve body 8, and as the two rotating blocks 24 are slowly rotated and adjusted on the top of the corresponding mounting frame 21, the multiple nozzles 25 can be driven to spray the water mist evenly on the surface of the valve body 8, and at the same time, the telescopic ends of the multiple second electric telescopic rods 20 are controlled to extend upward, and the two clamping plates 12 and the valve body 8 are driven to move upward to a specified height. Then, with the help of the two first motors 22, the two clamping plates 12 and the clamped and fixed valve body 8 are driven to rotate slowly together, so that the multiple nozzles 25 can spray the water mist more comprehensively on the surface of the valve body 8, and the anti-fog performance test of the valve body 8 is carried out, and the performance of the valve body 8 in a humid environment is tested and evaluated.

[0047] After the anti-fog performance test of the valve body 8, a small amount of liquid remains on the surface and inside of the valve body 8. If the anti-fog performance test of the valve body 8 is passed, the telescopic ends of the multiple second electric telescopic rods 20 are in an extended state, and the two first motors 22 can be used to drive the valve body 8 to rotate quickly, so that the residual liquid inside and on the surface of the valve body 8 can be thrown out, thereby reducing the problem of liquid remaining inside and on the surface of the valve body 8, which will have an adverse effect on subsequent other performance tests of the valve body 8, so that the valve body 8 can be quickly put into subsequent performance testing work.

[0048] Electric heating plates 23 are arranged inside the two clamping plates 12. After the waterproof fog performance test of the valve body 8 is completed, the two electric heating plates 23 can be controlled to be powered on for heating, and the temperature is transmitted to the inside of the valve body 8 through the two electric heating plates 23, so as to simulate the use environment of the valve body 8 in different temperatures during actual use, and test the optimal temperature application range of the valve body 8;

[0049] When the above-mentioned different temperature tests are performed on the valve body 8, it can also be combined with the above-mentioned sealing performance test of the valve body 8 to simulate the use of the valve body 8 in actual use for opening and closing the gas or liquid transportation at different temperatures, and test whether the sealing performance and other related performances of the valve body 8 are affected;

[0050] At the same time, the high temperature generated by the two electric heating plates 23 is transmitted to the interior of the valve body 8, and the liquid moisture inside the valve body 8 that could not be completely removed in the previous test step can be accelerated to dry, which is beneficial to the subsequent testing of other related performances of the valve body 8.

[0051] After the valve body 8 passes the use environment test at different temperatures, the electromagnet inside the fixed block 2 can be controlled to be powered off, the limit fixation of the rotating plate 7 inside the fixed block 2 can be released, and the second motor 13 can be controlled to start, driving the driving block 17 to rotate in the cavity. During the rotation process, the driving block 17 can continuously push the rotating plate 7 to rotate up and down inside the fixed block 2, thereby simulating the use of the valve body 8 in a vibration environment, and testing the reliability and stability of the valve body 8 in the vibration environment;

[0052] Moreover, after the driving block 17 is rotated 90 degrees from its original state, the driving block 17 can lift the rotating plate 7 upward in the fixed block 2, driving the valve body 8 to be in a skewed state on the top of the rotating plate 7, simulating the situation where the valve body 8 is used in an uneven environment, and testing whether the valve body 8 can continue to be used normally at this time. Combined with the other valve body 8 performance tests mentioned above, the authenticity and reliability of the relevant performance test data of the valve body 8 are further enriched.

[0053] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
