Description

Technical Field

[0001] This invention relates to the field of valve island controller testing technology, and in particular to valve island controller performance testing equipment and testing methods. Background Technology

[0002] Currently, there is a lack of testing equipment for valve island controllers on the market. The performance of each valve island controller cannot be guaranteed before it is put into use. Testing it in actual work requires each valve island controller to correspond to a set of valve island components, and different valve island controllers correspond to different valve island components, which is inefficient. As the number of valve island controllers increases, the cost and space occupancy also increase, which greatly affects the testing efficiency of valve island controllers. Summary of the Invention

This testing equipment is small in size, easy to operate, and low in cost. It can meet the performance testing requirements of valve island controllers and the requirements of assembly line testing. It is also portable. The testing method is simple in steps and can not only meet the testing requirements for various performance aspects of valve island controllers, but also improve the accuracy of testing and meet the requirements of assembly line production.

[0060] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0062] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0063] like Figures 1 to 3 As shown, the valve island controller performance testing device of the present invention includes a master station 1 and a master station load, a slave station 2 and at least one set of slave station loads 11 disposed on the master station 1. In this application, the master station 1 refers to the circuit board.

[0064] The master station load is used to set test parameters, display test information, and send test commands. The master station load includes a display unit 10, a setting unit 19, and a power input unit. The display unit 10 is used to display test content and test results. The display unit 10 may include a monitor or a touch screen. The setting unit 19 is used to set test parameters. The setting unit 19 may include setting buttons, mainly including "up" button, "down" button, "setting" button, and "mode" button, but not limited to the above buttons.

[0065] The power input unit is used for power supply and includes a first power junction box 9, a second power junction box 3, an external power backup interface 7, and an external access button interface 18. The second power junction box 3, the external power backup interface 7, and the external access button interface 18 are all electrically connected to the first power junction box 9. The second power junction box 3 is connected to the slave station 2 via a valve island controller connection cable 4. The slave station 2 includes at least one valve island controller, which is electrically connected to the master station load and is used to parse test commands and feed back test information to the master station load. The valve island controller is equipped with a slave station indicator light 6 to indicate whether the valve island controller is working properly.

[0066] The external access button interface 18 can not only connect external buttons, but also connect a cylinder to control the cylinder to move up and down, so that the cylinder presses the circuit board. The control circuit board has good contact, and the operation is simple and convenient, realizing a single-person operation of the testing line.

[0067] The slave load 11 is used to run tests according to the parsed test instructions; the master load also includes a control unit 22, which has a first switch 23 for implementing a three-position dial and a second switch 24 for verifying the slave 2. The first switch 23 is used to control the number of slave loads 11. The slave loads 11 in this application consist of three sets of relays, each set of relays including 16 relays arranged side by side. The master station 1 is provided with slave load indicator lights 12 corresponding to the slave loads 11 one by one, which are used to indicate when the slave loads 11 are working. When the corresponding relay is connected to the circuit, the corresponding slave load indicator light 12 lights up, indicating normal operation. The three-position dial of the first switch 23 is used to control the first set of relays (i.e., 16 relays), the first and second sets of relays (i.e., 32 relays), and the first, second, and third sets (i.e., 48 relays), respectively. The second switch 24 is used to control the model selection of the valve island controller.

[0068] The master station load also includes an on / off load 13 and a short-circuit creation load 14. Both the on / off load 13 and the short-circuit creation load 14 are electrically connected to the first power supply junction box 9. The on / off load 13 and the short-circuit creation load 14 correspond to each group of slave station loads 11 and are used to control the on / off and short-circuit control of each group of 16 relays. An on / off load indicator light 16 is provided on one side of the on / off load 13 to indicate whether the on / off load 13 is working properly. A short-circuit creation indicator light 15 is provided on one side of the short-circuit creation load 14 to indicate whether the short-circuit creation load 14 is working properly.

[0069] The master station load also includes a grounding test unit 5, used to control grounding tests of at least one of the master station load, slave station 2, and slave station load 11. The grounding test unit 5 includes a relay for grounding testing, facilitating grounding testing by the valve island controller.

[0070] The main station load also includes a running load 20, used to control the power conversion of slave station 2. The running load 20 includes two relays, which convert the circuit to 24V L+ and 24V L- before loading it onto the valve island controller, improving the stability of the valve island controller's operation. Simultaneously, the circuit board is equipped with indicator lights 21, electrically connected to the running load 20, used to display the operating status. Indicator lights 21 include a "pass" indicator light, a "fail" indicator light, and a "running" indicator light, used to indicate that the inspection is passed, failed, and is in progress, respectively.

[0071] The main station load also includes a mute unit 17, which is used to turn off the sound. The mute unit 17 mainly includes a mute button. A buzzer can be installed on the main station. When an abnormality occurs, the buzzer will emit a sound to provide an audible alert. Pressing the mute button will turn off the buzzer.

[0072] The master station load sets test parameters and sends test commands. The valve island controller parses the test commands and controls the slave station load 11 to run the test according to the parsed test commands, thereby realizing the performance detection of the valve island controller.

[0073] This testing equipment is small in size, easy to operate, and low in cost. It can meet the performance testing requirements of valve island controllers and the requirements of assembly line testing.

[0074] A method for testing the performance of a valve island controller (e.g.) Figures 4 to 10 As shown), the valve island controller performance testing equipment described above is used, and the following steps are included:

[0075] 1) Main station assembly

[0076] a. First, manually place the main station horizontally into the inspection slot 53 on the inspection table 26, so that the first power junction box and the external access button interface on the main station are aligned with the through hole 56 on the inspection table 26, while ensuring that the second power junction box on the main station is located near the plug slot 26 on the inspection table 26.

[0077] The inspection table 26 is fixedly installed on the base plate 25. The inspection slot 53 is formed vertically downward along the top surface of the inspection table 26. Two through holes 56 are located on the inspection table 26 and connect to the inspection slot 53. The wire insertion slot 55 is located on the left side of the inspection table 26. The base plate 25 is equipped with a control switch 27 for controlling the operation of the wiring mechanism, the first lifting mechanism, the telescopic mechanism, the second lifting mechanism, and the clamping mechanism.

[0078] b. Then, by manually pressing the positioning block 54, the positioning block 54 presses against the top surface of the main station. This application uses two positioning blocks 54 distributed on the left and right sides of the inspection table 26, which facilitates horizontal movement along the inspection table 26, meets the requirements of the main station to be pressed or released, and further improves the stability and reliability of the valve island controller during insertion and removal.

[0079] 2) Power on the main station and set the parameters.

[0080] a. First, connect the external power cord and gas pipe to the wiring mechanism 32. Press the start switch on the control panel 57 and start the control panel 57. Press the first button on the control panel 57 to start the wiring mechanism 32. After the wiring mechanism 32 is inserted into the through hole, it is connected to the first power junction box 9 and the external access button interface 18 to turn on the power to the main station. (When the main station needs to be powered off, press the first button again to disconnect the wiring mechanism from the first power junction box and the external access button interface.)

[0081] The wiring mechanism 32 specifically includes a second plug box 59 (which can be connected to a solenoid valve via a wire) and a first plug box 60. The second plug box 59 is fixedly connected to the first plug box 60 via a fixing rod 61. Both the second plug box 59 and the first plug box 60 are provided with a socket 62 and a connector 63 to facilitate connection with an external gas pipe or power cord. The connector 63 facilitates the connection of the first plug box 60 and the second plug box 59 to the first power junction box and the external access button interface, respectively. The sides of the second plug box 59 and the first plug box 60 are movable and connected to the inspection table 26 via a pusher assembly.

[0082] The booster assembly specifically includes a fourth cylinder 64, a fourth piston rod 65, a first connecting rod 66, a second connecting rod 67, and a booster rod 68. The fourth cylinder 64 is horizontally fixed on the side of the inspection table 26. The fourth cylinder 64 is connected to the first connecting rod 66 through the fourth piston rod 65. A limiting groove 52 is provided on the side of the inspection table 26. The second connecting rod 67 is fixed on the side of the second connector box 59 and the first connector box 60. The second connecting rod 67 is connected to the first connecting rod 66 through the booster rod 68. The fourth piston rod 65 is driven to move horizontally by the fourth cylinder 64, which in turn drives the first connecting rod 66 to move along the limiting groove 52. This allows the booster rod 68 to drive the second connector box 59 and the first connector box 60 to move horizontally via the second connecting rod 67, facilitating the connection of the main station.

[0083] b. Then, along the side of the inspection table 26, manually pass one end of the valve island controller connection cable through the cable slot and fix it to the second power junction box 4 on the main station 1. At the same time, fix the other end of the valve island controller connection cable to the auxiliary clamp of the clamping mechanism 31 so that the plug is kept vertically downward.

[0084] c. Parameter settings are performed through the main station 1. Specific parameter settings include selecting the IO-Link controller (including manufacturer information and model), setting the external power supply voltage, power-on time, response time acceptable range, selecting whether to perform a short-circuit test, whether to download firmware, and selecting the firmware model. Simultaneously, the dimensions of the valve island controller under test can be determined via the control panel, which controls the second motor to drive the main clamping mechanism, facilitating the clamping of the valve island controller.

[0085] 3) Testing facility commissioning

[0086] a. Press the second button on the control panel to start the first lifting mechanism 28. The first lifting mechanism 28 drives the telescopic mechanism 29 and the second lifting mechanism 30 to move along the Z-axis to the desired height position.

[0087] b. Then press the third button on the control panel to make the telescopic mechanism 29 drive the second lifting mechanism 30 to move along the X-axis.

[0088] c. Next, press the fourth button on the control panel to start the telescopic mechanism 29. The telescopic mechanism 29 drives the second lifting mechanism 30 to move along the Y-axis, so that the second lifting mechanism 30 moves horizontally to the desired position until the clamping mechanism 31 connected to the second lifting mechanism 30 is adjusted to the desired position.

[0089] The first lifting mechanism 28 specifically includes a column 33, a lifting plate 34, a first cylinder 35, and a first piston rod 36.

The top surface of the lifting plate 34 is provided with a first motor 37 and a first baffle 39. The first motor 37 is connected to the first baffle 39 via a first screw 38. The horizontal moving plate 40 is connected to the first screw 38. The first motor 37 drives the first screw 38 to rotate, which in turn drives the telescopic mechanism 29 and the second lifting mechanism 30 to move horizontally, thereby adjusting the horizontal position of the clamping mechanism 31.

[0092] The clamping mechanism 31 specifically includes a lifting block 69, a main clamp, an auxiliary clamp, and a fixed guide plate 70. The lifting block 69 is connected to the bottom end of the third piston rod 58. Two sets of fixed guide plates 70 are distributed on both sides of the lifting block 69. The fixed guide plate 70 is provided with a guide groove 74. The main clamp is movably connected to the fixed guide plate 70, and the auxiliary clamp is located on one side of the lifting block 69.

[0093] The main fixture includes a moving bar 75, a clamping arm 77, and a pressure plate 78. A pusher block 76 is provided on the moving bar 75, confined within a guide groove 74 and moving horizontally along it. A second motor 71, a second baffle 72, and a second screw 73 are provided on a fixed guide plate 70. The second motor 71 is connected to the second baffle 72 via the second screw 73. The pusher block 76 is connected to the second screw 73, which has two threaded sections with opposite rotation directions to facilitate the movement of the moving bars 75 on both sides towards or away from each other. The clamping arm 77 is fixed to the moving bar 75. A reinforcing rod 79 is provided between two adjacent clamping arms 77 on the same side. The pressure plate 78 is located on the inner side of the clamping arm 77 and is distributed vertically for easy placement and removal of the valve island controller. An L-shaped stop bar 85 is provided on the rear clamping arm 77 to facilitate positioning of the valve island controller when it is placed into the main fixture.

[0094] The auxiliary clamp includes a fixed arm 80, a fifth cylinder 81, a fifth piston rod 82, and an arc-shaped block 83. The fixed arm 80 is mounted on the lifting block 69. The fifth cylinder 81 is fixed on the fixed arm 80. The fifth cylinder 81 is connected to the arc-shaped block 83 through the fifth piston rod 82. The arc-shaped block 83 is provided with a fastening block 84. The fifth cylinder 81 can drive the arc-shaped block 83 to move up and down through the fifth piston rod 82, which in turn can drive the connector of the valve island controller connection line to move up and down.
