[0002] Industrial PC motherboards are core hardware components designed specifically for industrial control scenarios, featuring high reliability, long lifespan, and strong environmental adaptability. They utilize industrial-grade components, support wide-temperature operation, and possess characteristics such as shock resistance, dust resistance, and electromagnetic interference resistance. They typically provide abundant industrial interfaces, supporting multiple network ports and serial port expansion. The motherboards use standardized dimensions and include a watchdog timer to ensure system stability, making them widely used in harsh industrial environments such as intelligent manufacturing, transportation, and energy.

[0003] The actual industrial environment is complex and changeable. Industrial control computer motherboards may face a variety of harsh conditions such as high temperature, low temperature, high humidity, and electromagnetic interference.

[0004] Existing testing equipment often only simulates single or a few environmental conditions, failing to comprehensively simulate real industrial scenarios. Industrial control computers operating in extreme climatic conditions may experience component damage and performance degradation after being put into use due to insufficient high and low temperature cycling and humidity variation testing during the initial testing phase, as they are unable to adapt to the environment. Therefore, we propose an automatic testing device for industrial control computer motherboards. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic testing device for industrial control computer motherboards, in order to solve the problem that the existing testing devices mentioned in the background art can often only simulate a single or a few environmental conditions, and cannot simulate real industrial scenarios in many aspects. Industrial control computers working under extreme climatic conditions may experience component damage and performance degradation after being put into use because they have not undergone sufficient high and low temperature cycles, humidity changes, etc. during testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic testing device for an industrial control computer motherboard, comprising: a testing platform, wherein a sliding groove is formed on the upper surface of the testing platform, a first anti-interference shield is slidably connected to the inner wall of the sliding groove, a second anti-interference shield is provided at one end of the first anti-interference shield, and the second anti-interference shield is slidably connected to the inner wall of the sliding groove, a clamping mechanism is provided on the upper surface of the testing platform, and a humidity simulation mechanism is provided at one end of the first anti-interference shield.

[0007] Preferably, the outer walls of the first and second anti-interference shields are fitted with sealing covers, and the clamping mechanism includes a support platform fixedly connected to the upper surface of the test platform.

[0008] Preferably, the upper surface of the support platform is provided with a square groove, the inner wall of the square groove is fitted with a bidirectional threaded rod, and the outer wall of the bidirectional threaded rod is threadedly connected with a limit block.

[0009] Preferably, an arc-shaped plate is fixedly connected to the upper surface of the limiting block, a fan-shaped plate is rotatably connected to one end of the arc-shaped plate, a rubber block is rotatably connected to one end of the fan-shaped plate, and a knob is fixedly connected to one end of the support platform.

[0010] Preferably, the humidity simulation mechanism includes a water tank fixedly connected to the upper surface of the test platform, a water pipe fixedly connected to the upper surface of the water tank, and a booster pump fixedly connected to the upper surface of the sealing cover.

[0011] Preferably, one end of the booster pump is fixedly connected to one end of the water pipe, an atomizing nozzle is fixedly connected to the bottom of the booster pump, a heating component is fixedly connected to the inner wall of the test platform, and a temperature controller is fixedly connected to one end of the heating component.

[0012] This utility model has at least the following beneficial effects:

[0013] (1) By coordinating the humidity simulation mechanism, heating components, and temperature controller, the system can simulate the testing of industrial control computer motherboards in humid environments. This makes the testing environment closer to real-world usage scenarios, ensuring that the test results are more valuable and preventing motherboard failures due to humidity issues during actual use. The high-temperature simulation mechanism allows the motherboard to be tested in high-temperature environments, exposing defects in heat dissipation design and component high-temperature resistance in advance.

[0021] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: an automatic testing device for an industrial control computer motherboard, comprising: a testing platform 1, a sliding groove 2 formed on the upper surface of the testing platform 1, a first anti-interference shield 3 slidably connected to the inner wall of the sliding groove 2, a second anti-interference shield 4 provided at one end of the first anti-interference shield 3, and the second anti-interference shield 4 slidably connected to the inner wall of the sliding groove 2, a sealing cover 5 placed on the outer wall of the first anti-interference shield 3 and the second anti-interference shield 4, a clamping mechanism 6 provided on the upper surface of the testing platform 1, and a humidity simulation mechanism 7 provided at one end of the first anti-interference shield 3.

[0023] The outer walls of the first anti-interference shield 3 and the second anti-interference shield 4 are fitted with sealing covers 5. The clamping mechanism 6 includes a support platform 61 fixedly connected to the upper surface of the test platform 1. The upper surface of the support platform 61 is provided with a square groove 62. A bidirectional threaded rod 63 is installed on the inner wall of the square groove 62. A limit block 64 is threadedly connected to the outer wall of the bidirectional threaded rod 63. An arc plate 65 is fixedly connected to the upper surface of the limit block 64. A fan-shaped plate 66 is rotatably connected to one end of the arc plate 65. A rubber block 67 is rotatably connected to one end of the fan plate 66. A knob 68 is fixedly connected to one end of the support platform 61.

[0024] When the motherboard needs to be secured, the operator places it on the support platform 61. The operator then rotates the knob 68, causing the bidirectional threaded rod 63 to rotate. The two sets of limiting blocks 64 on the bidirectional threaded rod 63, limited by the square groove 62, move towards each other, causing the two sets of arc-shaped plates 65 to move towards each other, creating a clamping effect and securing the motherboard. During clamping, the fan-shaped plate 66 rotates on the arc-shaped plate 65, and the rubber block 67 rotates on the fan-shaped plate 66, adapting to the motherboard's surface contour and tightly fitting gaps and recesses. The clamping mechanism 6 is compatible with various motherboard specifications, enhancing the device's versatility. Users do not need to replace the entire testing equipment; they only need to adjust the clamping mechanism to quickly switch between testing different motherboard models, reducing equipment procurement and maintenance costs. In addition, the rubber block 67 can automatically adjust the clamping position according to the actual shape of the motherboard, and can fit tightly into gaps and recesses to provide uniform and stable clamping force. Using the rubber block 67 as a clamping plate, its soft texture can effectively avoid physical damage to the motherboard surface, solder joints and precision components during clamping, compared with metal or hard plastic clamping plates, greatly reducing the motherboard damage rate caused by improper testing operations.

[0025] The humidity simulation mechanism 7 includes a water tank 71 fixedly connected to the upper surface of the test platform 1. A water pipe 72 is fixedly connected to the upper surface of the water tank 71. A booster pump 73 is fixedly connected to the upper surface of the sealing cover 5. One end of the booster pump 73 is fixedly connected to one end of the water pipe 72. An atomizing nozzle 74 is fixedly connected to the bottom of the booster pump 73. A heating component 8 is fixedly connected to the inner wall of the test platform 1. A temperature controller 9 is fixedly connected to one end of the heating component 8.

[0026] When a simulated humidity test is required, the operator places the first anti-interference shield 3 and the second anti-interference shield 4 on the slide 2, and then pushes them to move in the same direction to form a closure. The sealing cover 5 works in conjunction with the first anti-interference shield 3 and the second anti-interference shield 4 to keep the detection of the industrial control computer motherboard in a closed state. The sealing cover 5 and the two sets of interference shields are all made of anti-interference metal materials, which can shield external electromagnetic interference and improve the accuracy of the test.

[0027] Meanwhile, the operator starts the booster pump 73, which draws water from the water tank 71 through the water pipe 72. The water is then sprayed from the atomizing nozzle 74 to form a water mist, creating a simulated high-humidity environment for testing the industrial control computer motherboard. When it is necessary to simulate high-temperature testing of the motherboard, the heating component 8, which is a heating wire, efficiently converts electrical energy into heat energy to heat the testing space of the industrial control computer motherboard formed by the sealing cover 5 and the two anti-interference covers. By raising the temperature in this enclosed space, the operating state of the motherboard under high-temperature conditions can be accurately simulated, thereby effectively evaluating its temperature adaptability. At the same time, the temperature controller 9 can precisely regulate the operating temperature of the heating component 8 to ensure that the temperature of the test environment is stable within the preset range.

[0028] By coordinating the humidity simulation mechanism 7, heating component 8, and temperature controller 9, the system can simulate the testing of industrial control computer motherboards in humid environments. This makes the testing environment closer to real-world usage scenarios, ensuring more valuable test results and preventing motherboard malfunctions due to humidity issues in actual use. The high-temperature simulation mechanism allows the motherboard to be tested in high-temperature environments, exposing deficiencies in heat dissipation design and component high-temperature resistance in advance. Addressing these issues before product release can significantly reduce the product's failure rate in actual use, minimizing maintenance costs and production downtime losses due to equipment failure.
