Description
An industrial logic controller testing and calibration device Technical Field
[0001] This utility model relates to the field of industrial logic controller testing technology, and in particular to an industrial logic controller testing and calibration device. Background Technology
[0002] An industrial logic controller (PLC) is a microprocessor-based digital control unit used for automation control. It can load control instructions into memory for storage and execution. A PLC consists of a CPU, instruction and data memory, input / output interfaces, a power supply, and digital-to-analog converters. Early PLCs only had logic control functions, hence the name. Later, with continuous development, these initially simple computer modules have evolved to include various functions such as logic control, timing control, analog control, and multi-machine communication.
[0003] Existing industrial logic controller testing and calibration devices, when testing and calibrating newly manufactured industrial logic controllers, require different wiring depending on the type of industrial logic controller and the functions of the components to be tested and calibrated. Each industrial logic controller requires the connection of many wires, which carries a high probability of incorrect wire connections. Furthermore, manually connecting each test point is time-consuming, which does not meet the goal of efficient and rapid production. In addition, existing mainstream testing fixtures are designed for testing PCB boards rather than assembled industrial logic controllers. Fixtures for testing PCB boards are mostly vertical in direction, which is inconvenient to operate. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing industrial logic controller testing and calibration devices. When testing and calibrating newly manufactured industrial logic controllers, the different types of industrial logic controllers and the different functions of the components to be tested and calibrated result in varying wiring requirements. Furthermore, each industrial logic controller requires numerous wiring connections, leading to a high probability of incorrect wire connections. Manually connecting each test point is also time-consuming, failing to meet the goal of efficient and rapid production. Additionally, existing mainstream testing fixtures are designed for PCB boards rather than assembled industrial logic controllers, and the operating direction of fixtures for PCB board testing is mostly vertical, resulting in inconvenient operation. Therefore, this invention provides an industrial logic controller testing and calibration device.
[0005] The purpose of this utility model is achieved through the following technical solution: an industrial logic controller test and calibration device, including a test platform, in which a detachable standard sample and a test calibration component are installed. A sliding base plate is installed on both sides of the test calibration component. Probes for testing the upper terminals of the test calibration component are installed on the side of the two sliding base plates closest to the test calibration component. Two sets of sliding grooves corresponding to the sliding base plates are opened on the test platform. Two sets of electric push cylinders are installed at the bottom of the test platform. The moving ends of the two sets of electric push cylinders pass through the two sets of sliding grooves and are connected to the two sets of sliding base plates. An action switch electrically connected to the two sets of electric push cylinders is installed on the test platform.
[0006] The terminals on both sides of the standard sample are connected to two sets of probes via wires. The standard sample communicates with an external host computer. By using an electric pusher cylinder to move the translation base plate and probes, the terminals on the standard sample can make contact with the terminals to be tested on the test calibration piece. This eliminates the need for wiring on the test calibration piece. The pre-connected wires between the standard sample and the probes prevent incorrect wiring later, ensuring the accuracy of the test. Furthermore, the electric pusher cylinder is controlled by an actuation switch to move the translation base plate and probes, making operation convenient and achieving the goal of rapid testing of the test calibration piece, effectively improving work efficiency.
[0007] A further technical solution is that the testing platform is assembled from multiple sets of bakelite boards, which are detachably connected. By setting the testing platform to be assembled from multiple sets of bakelite boards, it can be arranged and adjusted according to different test calibration parts, thereby testing different types of test calibration parts and improving the applicability of the equipment. At the same time, bakelite boards have the characteristics of being non-absorbent, non-conductive, heat-resistant, and high-strength, which effectively improves the service life of the equipment.
[0008] A further technical solution is to install a power supply at the bottom of the testing platform, which is used to supply power to the standard sample, the test calibration sample, and the electric push cylinder respectively.
[0009] A further technical solution is that the testing platform is equipped with two sets of fixing slots corresponding to the standard sample and the test calibration piece, respectively. Both the standard sample and the test calibration piece are engaged with the fixing slots. By setting the fixing slots, it is easy to position and engage the standard sample and the test calibration piece, thereby ensuring the stability of their positions on the testing platform and facilitating accurate probe docking.
[0010] A further technical solution is to use a flexible telescopic probe. Setting the probe to be a flexible telescopic probe can ensure that the probe can press tightly against the wiring terminals of the test calibration component, avoiding problems with poor contact.
[0011] A further technical solution is to install two sets of slide rails on the testing platform, each corresponding to a different set of translation base plates. The bottom of the translation base plate is slidably connected to the slide rails. By setting the slide rails, the translation base plate can be made more stable during movement, ensuring more accurate docking between the probes on the translation base plate and the test calibration pieces.
[0012] This invention has the following advantages: By setting an electric pusher cylinder to move the translation base plate and probe, the terminals on the standard sample can be brought into contact with the terminals to be tested on the test calibration piece, eliminating the need for wiring on the test calibration piece. The pre-connection of the wires between the standard sample and the probe can avoid the problem of incorrect wire numbers later, ensuring the accuracy of the test. Furthermore, the electric pusher cylinder is controlled by an action switch to move the translation base plate and probe, making the operation convenient and achieving the purpose of rapid testing of the test calibration piece, effectively improving work efficiency.

Two sets of sliding grooves 7, corresponding to the translational base plates 4, are opened on the testing platform 1. Two sets of electric push cylinders 6 are installed at the bottom of the testing platform 1. The moving ends of the two sets of electric push cylinders 6 pass through the two sets of sliding grooves 7 and are connected to the two sets of translational base plates 4. An actuating switch 10 electrically connected to the two sets of electric push cylinders 6 is installed on the testing platform 1.
[0023] The terminals on both sides of the standard sample 2 are connected to two sets of probes 5 respectively through wires. The standard sample 2 is connected to an external host computer and can communicate with the host computer through signal input and output ports such as RJ45 interface to obtain whether the parameters of the test calibration component 3 are qualified and make adjustments. The standard sample 2 and the test calibration component 3 are single or multiple modules that are compatible with each other, and both the standard sample 2 and the test calibration component 3 are industrial logic controllers.
[0024] By setting the electric push cylinder 6 to move the translation base plate 4 and probe 5, the terminals on the standard sample 2 can be made in contact with the terminals to be tested on the test calibration piece 3, eliminating the need for wiring on the test calibration piece 3. The pre-connection of the wires between the standard sample 2 and the probe 5 can avoid the problem of incorrect wire numbers later, ensuring the accuracy of the test. Furthermore, the electric push cylinder 6 is controlled by the action switch 10 to move the translation base plate 4 and probe 5, making the operation convenient and achieving the purpose of rapid testing of the test calibration piece 3, effectively improving work efficiency.
[0025] The testing platform 1 is assembled from multiple sets of bakelite boards, which are detachably connected. By setting the testing platform 1 to be assembled from multiple sets of bakelite boards, it can be arranged and adjusted according to different test calibration parts 3, thereby testing different models of test calibration parts 3, improving the applicability of the equipment. At the same time, bakelite boards have the characteristics of being non-absorbent, non-conductive, heat-resistant, and high-strength, which effectively improves the service life of the equipment.
[0026] A power supply 11 is installed at the bottom of the testing platform 1. The power supply 11 is used to supply power to the standard sample 2, the test calibration sample 3 and the electric push cylinder 6 respectively.
[0027] The testing platform 1 is equipped with two sets of fixing slots 9, which correspond to the standard sample 2 and the test calibration piece 3 respectively.

[0028] Probe 5 is an elastic telescopic probe. Setting probe 5 as an elastic telescopic probe can ensure that probe 5 can press tightly against the wiring terminal of test calibration component 3, avoiding the problem of poor contact.
[0029] The testing platform 1 is equipped with two sets of slide rails 8, which correspond to the two sets of translation base plates 4 respectively.

The power supply 11 is connected to the standard sample piece 2, the test calibration piece 3 and the electric push cylinder 6 in sequence. When the test starts, the electric push cylinder 6 drives the translation base plate 4 to move towards the test calibration piece 3, so that the probe 5 on the translation base plate 4 contacts the terminal to be tested on the test calibration piece 3. At this time, the standard sample piece 2 connected to the probe 5 communicates with the external host computer through the network cable on the RJ45 interface, thereby obtaining whether the parameters of the test calibration piece 3 are qualified and making adjustments. The test and calibration results will appear on the display interface of the external host computer, which can save the work of terminal wiring and quickly connect and disconnect the necessary data points of the test calibration piece 3, thereby realizing the rapid test and calibration of the industrial logic controller.
