[0033] A placement opening 3 is provided on one side of the cabinet 1 , with multiple placement openings 3 corresponding to each fixture assembly 2 ;

[0034] A heating assembly comprising: a heating channel 4 disposed in the cabinet 1, and a heating element 5 and a fan 6 respectively located in the heating channel 4, wherein the heating channel 4 passes through each product to be tested;

[0035] The sealed door assembly includes a plurality of sealed doors 13 movably connected to the placement opening 3. The sealed doors 13 are used to seal or open the placement opening 3. The sealed doors 13 correspond to the placement opening 3 one by one, and each of the sealed doors 13 can be opened and closed independently.

[0036] The utility model describes a high-temperature aging test device, in which the products to be tested are placed on the corresponding fixture components 2 through the placement openings 3. The placement mechanism is composed of a plurality of fixture components 2 stacked up and down, with placement space between the fixture components 2. The sealed door component is closed to prevent hot air from leaking out. The airflow blown out by the fan 6 is heated to a preset aging test temperature through the heating component. The fan 6 blows the hot air into the heating channel 4 and makes the hot air flow in the heating channel 4. The hot air passes through each product to be tested, placing it in a high-temperature environment, and performing a heating test on the product to be tested.

[0037] During the test, a temperature sensor monitors the temperature within the heating chamber and feeds the temperature signal back to the control system. Based on the temperature signal, the control system adjusts the power of the heating element 5 to maintain the temperature within the heating chamber at or above the set value and prevent it from overheating. When the test time reaches the set value, the heating element is turned off. Once the temperature within the heating chamber has dropped to a safe level, the sealed door assembly is opened, the product under test is removed, and the high-temperature aging test is completed.

[0038] Reference Figure 1As shown, multiple jig assemblies 2 are arranged along the first direction of the cabinet 1, and there is a first spacing space between the placement mechanism and the wall on one side of the cabinet 1 along the first direction.

A second spacing space and a third spacing space are respectively provided between the baffle 9 and the cabinet 1. The two ends of the first spacing space are respectively connected with the second spacing space and the third spacing space, so that the gas blown out by the fan 6 in the first spacing space first enters the second spacing space, passes through the corresponding jig assemblies 2 through the through holes of multiple baffles 9 in the second spacing space, and is blown out to the third spacing space from the other side, and flows back to the first air outlet of the fan 6 in the third spacing space, and is connected end to end through the first spacing space, the second spacing space, the placement space between the jig assemblies 2, and the third spacing space to form an internal circulation channel, so that the heating channel 4 is constituted as a circulation channel.

[0039] The cabinet body 1 is provided with a first air outlet, which is connected to a first spacing space. The first air outlet is provided with an electromagnetic air valve 10. The first spacing space is provided with a filter element 7 on the input side of the fan 6, and the heating element 5 is provided on the output side of the fan 6. The output side of the heating element 5 is also provided with an air guide plate 8. The opening and closing of the first air outlet and the size of the opening are controlled by the electromagnetic air valve 10. After the test is completed, the electromagnetic air valve is opened, and the fan is used to cooperate with the first air outlet to let in cold air, fill the space inside the cabinet and discharge the hot air generated by heating inside the cabinet, thereby quickly cooling the space inside the cabinet.

[0040] The placement mechanism is provided with a rear panel on one side along the third direction of the cabinet 1, and the sealed door assembly is provided on the other side of the placement mechanism along the third direction. The rear panel on the rear side of the cabinet 1 seals the back of the cabinet 1 to maintain the airtightness of the space of the cabinet 1.

The push plate 12 can drive the first lifting shaft 15, and the two-axis drive assembly 21 drives the push plate 12 to move in the first direction or the third direction, thereby approaching and pushing the first lifting shaft 15 up and down. When the first lifting shaft 15 is pushed upward, it can drive the sealed door 13 to move. The sealed door 13 is rotatably connected to the cabinet 1 through the first swing arm 14, thereby moving upward to open the placement port 3, and the product to be tested can be placed on the fixture assembly 2. When the sealed door 13 needs to be closed, the reverse operation is sufficient.

[0042] The cabinet body 1 is also provided with a guide rail along the third direction, and the guide rail is slidably connected to the support body 16.

The support body 16 is provided with a second lifting shaft 20, and the push plate 12 can drive the second lifting shaft 20. By pushing the second lifting shaft 20 upward by the push plate 12, the plurality of second swing arms 19 can be synchronously pushed and rotated, driving the sealing door 13 to close downward, and all the sealing doors 13 can be closed at the same time. Since the gravity of the sealing door 13 itself is downward when closing the sealing door 13 downward, less thrust is required to push it downward, and all of them can be pushed. The rotational resistance of the first swing arm 14 and the second swing arm 19 is greater than the gravity of the sealing door 13.

[0043] Reference Figure 2 As shown, in order for the push plate 12 to push the first lifting shaft 15 and the second lifting shaft 20 upward respectively to realize the opening and closing of the sealing door 13 respectively, the position of the first lifting shaft 15 on the first swing arm 14 is located between the fulcrum of the sealing door 13 and the first swing arm 14 and the fulcrum of the cabinet body 1 and the first swing arm 14, the second lifting shaft 20 is installed on the support body 16, and the fulcrum of the cabinet body 1 and the second swing arm 19 is located between the fulcrum of the sealing door 13 and the second swing arm 19 and the fulcrum of the support body 16 and the second swing arm 19.

The third spacing space is connected to the outside world through the second air outlet. In this embodiment, the second air outlet is located below the third spacing space, and the third spacing space is a return channel. The outside air and the heat return air return channel enter the air inlet of the fan 6. The filter element 7 is arranged between the return channel and the air inlet of the fan 6, and the filter element 7 is sealed in the first spacing space.

[0045] The wall of the cabinet 1 is provided with an insulation board 17. The insulation board 17 is a material with good thermal insulation performance, such as rock wool, glass wool or polyurethane. It plays the role of heat insulation and reduces the loss of heat to the external environment. A smoke sensor and / or a temperature sensor is also provided in the heating space. The temperature sensor measures the temperature in the heating space in real time before and during the test, and transmits the temperature data to the temperature control system. The temperature control system adjusts the working state of the heating component according to the preset temperature value and the feedback information of the temperature sensor. If the temperature is lower than the set value, the heating component will increase the power and increase the heating speed; if the temperature reaches or exceeds the set value, the heating component will reduce the power or stop working to maintain the temperature in the heating space stable within the set range.

[0046] Reference Figure 1 As shown, a plurality of guide plates 18 are provided on the inner wall of the cabinet 1 , and the guide plates 18 are tilted along the transmission direction of the heated gas, and the sizes of the plurality of guide plates 18 gradually increase in the direction away from the fan 6 .
