[0026] In order to enable personnel in the technical field to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.

[0027] Electromagnetic valve detection involves many aspects. A conventional test bench can only test the action of the electromagnetic valve after the electromagnetic valve is powered on or powered off, that is, test the working condition of the electromagnetic valve in an ideal state, and does not support the detection of internal leakage and external leakage of the electromagnetic valve. The internal leakage of the electromagnetic valve refers to the situation that the medium leaks from the valve core to the outside laterally when the valve is closed. Such leakage is mostly caused by damage to the sealing element or displacement during assembly. The reasons for internal leakage can include: erosion and wear of the medium, which causes the valve to be not tightly closed, even if the valve rod is tightened in place, because there is still a gap between the valve core and the valve body, the medium can still flow through; impurities blockage, valve core wear or internal seal damage, etc. can also cause internal leakage; aging of the sealing material of the electromagnetic valve or expiration of the service life, or damage to the sealing material due to the medium problem; the working environment exceeds the working range of the electromagnetic valve, and the electromagnetic valve is long-term high-load working, which causes internal leakage. The external leakage of the electromagnetic valve refers to the leakage of the medium from the outside of the valve body shell, which is usually caused by the following reasons: the sealing between the valve and the connecting flange or the connecting thread is not tight, causing the medium to flow out of the connecting sealing surface, or the sealing between the valve rod and the gland is not tight, causing the medium to leak; the valve body blank has a sand eye or the valve body is worn due to medium erosion; improper installation causes unstable operation of the electromagnetic valve, causing damage to the flange and the thread; due to incomplete cleaning of impurities, or insufficient cleanliness of the working environment, impurities enter the electromagnetic valve, affecting normal operation and accelerating wear of the sealing components of the electromagnetic valve.

[0028] In order to solve the above problems, the present application provides an electromagnetic valve assembly testing device which can automatically test the internal leakage and external leakage of different types of electromagnetic valves in a simple and convenient operation mode.

[0029] Referring to Figure 1 , an electromagnetic valve assembly testing device 100 according to an embodiment of the present application is introduced, which comprises a test module 101, the test module 101 comprising a test station 10, a first clamping assembly 20, a second clamping assembly 30, a third clamping assembly 40 and a gas leakage testing assembly (not shown in the figure).

[0030] The test station 10 is configured to be equipped with a fixture 50, which is configured to be adapted to a corresponding type of electromagnetic valve 300 to be tested. In the present embodiment, the test station 10 is configured to be equipped with at least two types of fixtures 50, so as to be adapted to different types of electromagnetic valves, thereby improving the versatility of the detection. For example, the test station 10 can be configured to support the detection of both the Baudel 2-position 2-way electromagnetic valve and the Baudel 2-position 3-way electromagnetic valve by replacing the fixture 50.

[0031] The first clamping assembly 20 and the second clamping assembly 30 are configured to apply opposite lateral clamping forces to the electromagnetic valve 300 to be tested on the test station. The first clamping assembly 20 can include a cylinder and a chuck driven by the cylinder, and similarly, the second clamping assembly 30 can also include a cylinder and a chuck driven by the cylinder. The cylinders of the first clamping assembly 20 and the second clamping assembly 30 can correspondingly drive the chucks to move, so as to clamp the electromagnetic valve 300 to be tested on the test station in the lateral direction.

[0032] The first clamping assembly 20 and the second clamping assembly 30 are configured to simultaneously connect the electromagnetic valve 300 to be tested to a test gas circuit when clamping the electromagnetic valve 300. Specifically, the fixture 50 is integrated with a gas supply port that can be externally connected to a gas source. When the chucks of the first clamping assembly 20 and the second clamping assembly 30 are driven to move towards each other to clamp the electromagnetic valve 300, the gas supply port is connected to the gas inlet of the electromagnetic valve 300 to be tested. In the present embodiment, the electromagnetic valve assembly test device 100 further includes a fixture 50 gas source interface 102 corresponding to the test module 101, and the gas supply port of the fixture 50 can be in gas communication with the fixture 50 gas source interface 102 to be externally connected to a gas source. In this way, the integration and operation convenience of the device are improved.

[0033] The third clamping assembly 40 is configured to apply a vertical clamping force to the electromagnetic valve 300 to be tested on the test station 10 towards the test station 10. The third clamping assembly 40 includes a cylinder and a power supply unit 41 that can be driven by the cylinder. In some embodiments, the third clamping assembly 40 can also be configured with a separate chuck to apply a vertical clamping force to the electromagnetic valve 300 to be tested by the chuck when driven by the cylinder. In some embodiments, the power supply unit 41 itself can serve as the main body to apply a vertical clamping force to the electromagnetic valve 300 to be tested, and the present application does not limit this.

[0034] The third clamping assembly 40 is configured to apply a vertical clamping force to the electromagnetic valve 300 to be tested on the test station 10 towards the test station 10. The third clamping assembly 40 includes a cylinder and a power supply unit 41 that can be driven by the cylinder. In some embodiments, the third clamping assembly 40 can also be configured with a separate chuck to apply a vertical clamping force to the electromagnetic valve 300 to be tested by the chuck when driven by the cylinder. In some embodiments, the power supply unit 41 itself can serve as the main body to apply a vertical clamping force to the electromagnetic valve 300 to be tested, and the present application does not limit this.

[0035] The electromagnetic valve assembly testing device 100 further comprises stroke switches and pressure detection switches arranged in cooperation with the cylinders of the first clamping assembly 20, the second clamping assembly 30 and the third clamping assembly 40. The stroke switches are used to detect whether the stroke of the cylinder is in place, and the pressure detection switches are used to detect the sealing performance of the test gas circuit, so that the tightness of the test circuit can be determined at the same time.

[0036] The air leakage testing assembly comprises a flow meter, a differential pressure transmitter and a pressure transmitter. The flow meter is used to detect the gas flow in the test gas circuit, the differential pressure transmitter is used to detect the pressure difference between the specified detection points in the test gas circuit, and the pressure transmitter is used to detect the gas pressure in the test gas circuit. The electromagnetic valve 300 on the test station 10 can be controlled to open and close to cooperate with the air leakage testing assembly to detect the internal leakage and / or external leakage of the electromagnetic valve 300.

[0037] For example, if the internal leakage of the electromagnetic valve is to be detected, the gas inlet of the electromagnetic valve can be connected to a gas source, and the gas outlet can be connected to the flow meter. Then, the pressure at the gas inlet of the electromagnetic valve is recorded when the electromagnetic valve is in a closed state, and the pressure is maintained for a certain period of time (usually 5-10 minutes). The reading of the flow meter is observed, and if the flow meter shows that gas is flowing out, it indicates that there is internal leakage, and the leakage amount is recorded. If the external leakage of the electromagnetic valve is to be detected, the differential pressure transmitter can be used to measure the pressure difference between the two ends of the electromagnetic valve. If there is external leakage, the pressure difference will decrease, because part of the gas will escape from the leakage point instead of passing through the electromagnetic valve. During the detection process, the pressure transmitter can detect the appropriate test pressure to meet the needs of different types of electromagnetic valves, different detection standards and detection scenarios.

[0038] In this embodiment, the electromagnetic valve assembly testing device 100 comprises at least two test modules 101, which can be controlled to synchronously detect the internal leakage and / or external leakage of the electromagnetic valve 300 thereon. In this way, the same test program can be called for synchronous testing of the same type of electromagnetic valve, thereby improving the testing efficiency of the electromagnetic valve.

[0039] The electromagnetic valve assembly testing device 100 further comprises an input assembly and a controller. The input assembly is used to obtain the type of the electromagnetic valve 300 to be tested, and the controller is used to control the opening and closing of the electromagnetic valve 300 to be tested according to the type of the electromagnetic valve 300 to be tested, so as to cooperate with the air leakage testing assembly to detect the internal leakage and / or external leakage of the electromagnetic valve 300 to be tested.

[0040] Exemplarily, the input component can be an operation keyboard, and an operator inputs according to a model of the electromagnetic valve 300 to be tested; or alternatively, the input component can be a code scanning gun, and the operator directly scans a bar code or a two-dimensional code on an order to automatically call a corresponding test program of the electromagnetic valve 300 to be tested, thereby further improving the versatility and convenience of the test bench. Further, the controller can be an integrated circuit including a micro controller unit (MCU). As known by those skilled in the art, the micro controller unit can include a central processing unit (CPU), a read-only memory (ROM), a random access memory (RAM), a timing module, an analog / digital conversion module (A / D converter), and a plurality of input / output ports. Of course, the control device can also adopt other forms of integrated circuits, such as application specific integrated circuits (ASIC) or field-programmable gate arrays (FPGA), and the present application does not limit this.

[0041] Referring to Figure 2 The electromagnetic valve assembly test bench 200 according to an embodiment of the present application is introduced, which comprises an assembly bench and an electromagnetic valve assembly test device 100 arranged on the assembly bench.

The preset interval here can be set according to the actual size of the test bench, and generally, the preset interval is set so that the operator cannot operate the first test starting switch 201 and the second test starting switch 202 with one hand. In this way, the operator needs to use both hands to correspondingly operate the first test starting switch 201 and the second test starting switch 202 to start the electromagnetic valve assembly test device 100, thereby forcibly ensuring the safety of the test process.

[0044] It should be noted that the "simultaneous force closure" of the first test start switch 201 and the second test start switch 202 here can refer to that the force closure time difference of the first test start switch 201 and the second test start switch 202 is within an acceptable range, for example, when the force closure time difference of the first test start switch 201 and the second test start switch 202 is within 0.5s, 0.3s or 0.2s, the electromagnetic valve assembly test device 100 can be turned on.

[0045] In the embodiment, the electromagnetic valve assembly test bench 200 further comprises a storage module (not shown in the figure), which is used to store the test data of the electromagnetic valve assembly test device 100, to facilitate subsequent problem finding and maintenance work of the electromagnetic valve, and to enrich the functions of the test bench. Moreover, the assembly bench comprises an assembly work area 204, and the electromagnetic valve assembly test bench 200 further comprises a torque gun hanger 203 movably arranged above the assembly work area 204, to facilitate the installation work of the electromagnetic valve, and the assembly bench and the test bench are integrated, thereby saving the work area area.

[0046] In one exemplary application of the electromagnetic valve assembly test bench 200 provided by the above embodiment to test the electromagnetic valve, the following steps are performed:

[0047] 1) Before the test starts, replace the corresponding clamp 50 according to the model of the electromagnetic valve to be tested 300, and after replacing the clamp 50, connect the air supply port on the clamp 50 to the clamp 50 air source interface 102, which is used to supply air to the air cylinder on the clamp 50 and the electromagnetic valve to be tested 300.

[0049] 3) Place the electromagnetic valve to be tested 300 on the corresponding position of the clamp 50, and simultaneously press the first test start switch 201 and the second test start switch 202 with both hands to start the test program.

[0050] 4) Before the above steps, the test bench can also be debugged and calibrated through the inlet pressure test point 207. After starting the test program, the opening and closing of the electromagnetic valve will be automatically controlled according to the pre-designed logic to control the opening and closing of the valve island, and then the action of the air cylinder will be controlled. First, the first clamping assembly 20 and the second clamping assembly 30 will act simultaneously to clamp the electromagnetic valve to be tested 300, and at the same time, the air circuit of the electromagnetic valve to be tested 300 will be connected, and then the third clamping assembly 40 will act to drive the power supply unit 41 of the electromagnetic valve to be tested 300 to press the electromagnetic valve to be tested 300, and at the same time, the control circuit of the electromagnetic valve to be tested 300 will be connected through the contact. In this process, whether the air cylinder is in place and whether the air circuit and the circuit are in close contact will be detected through the travel switch and the pressure detection switch.
