Description
Technical Field
[0001] The utility model relates to the technical field of component detection devices, in particular to a high and low temperature rapid temperature change test box for component climate simulation tests. Background Art
[0002] Electronic components are components of electronic elements and small machines and instruments. They are usually composed of several parts and can be used in similar products. They often refer to certain parts in industries such as electrical appliances, radios, and instruments. They are a general term for electronic devices such as capacitors, transistors, hairsprings, and springs. Common ones include diodes. With the improvement of technology, components need to be used in different environments. In nature, components are used in areas where high temperature and body temperature are converted. Therefore, it is necessary to use high and low temperature rapid temperature change devices to detect the operating status of components.
[0003] The high and low temperature rapid temperature change test chamber includes a low temperature chamber and a high temperature chamber. When the high and low temperature rapid temperature change test chamber is used to test components, the components are placed inside the high temperature chamber for testing, and then the components tested in the high temperature chamber are quickly moved to the low temperature chamber. When the positions of the components are changed, an opening needs to be formed between the high temperature chamber and the low temperature chamber to drive the movement of the components. However, when a passage is formed between the high temperature chamber and the low temperature chamber, the temperatures inside the high temperature chamber and the low temperature chamber will flow into each other. The temperatures that flow into each other will cause the problem of temperature neutralization. After the temperatures flow into each other, the problems inside the low temperature chamber and the high temperature chamber will change. For this reason, we propose a high and low temperature rapid temperature change test chamber for component climate simulation tests. Utility Model Content

The high temperature box 3 and the low temperature box 4 are installed on the inner side of the bracket 1 and the side positioning plate 2 in turn, and high temperature and low temperature areas are formed inside the high temperature box 3 and the low temperature box 4. A sealing plate 5 is provided at the front end of the high temperature box 3, and the sealing plate 5 seals the front end of the high temperature box 3 and the low temperature box 4. A fan 6 is installed on the upper part of the low temperature box 4, and the fan 6 drives the gas to circulate. A heating resistor 8 and a condensing device 7 are installed inside the high temperature box 3 and the low temperature box 4. The heating resistor 8 and the condensing device 7 transmit high temperature and low temperature states in turn. The inner side of the high temperature box 3 and the low temperature box 4 is provided with a sealing plate 5. The sealing plate 5 seals the front end of the high temperature box 3 and the low temperature box 4. A fan 6 is installed on the upper part of the low temperature box 4. The fan 6 drives the gas to circulate. A heating resistor 8 and a condensing device 7 are installed inside the high temperature box 3 and the low temperature box 4. The heating resistor 8 and the condensing device 7 transmit high temperature and low temperature states in turn. A movable sleeve 9 is provided, and the movable sleeve 9 is disassembled on the inner side of the high temperature box 3 and the low temperature box 4. A protective plate 10 is fixedly connected to the inside of the movable sleeve 9, and a first circular jacket 11 is fixedly connected to the inside of the protective plate 10. The inside of the first circular jacket 11 is movably sleeved with a second circular jacket 12, and the first circular jacket 11 is sleeved on the outside of the second circular jacket 12. When the second circular jacket 12 is flipped, the temperature inside the high temperature box 3 and the low temperature box 4 is prevented from blending and converting. A motor 13 is installed on one side of the second circular jacket 12, and the motor 13 drives the second circular jacket 12 to rotate. A positioning plate 14 is fixedly connected to the middle part of the inside of the second circular jacket 12, and clamping devices 15 are installed on the front and back sides of the positioning plate 14. The clamping device 15 flips the components.
[0025] See also Figure 5 The side positioning plates 2 are installed on both sides of the connection between the high-temperature box 3 and the low-temperature box 4. At the same time, fastening bolts are installed between the side positioning plates 2 and the high-temperature box 3 and the low-temperature box 4. By installing the high-temperature box 3 and the low-temperature box 4 on the inner side of the bracket 1 and the side positioning plates 2, the bracket 1 and the side positioning plates 2 can limit the positions of the high-temperature box 3 and the low-temperature box 4, thereby improving the stability of the high-temperature box 3 and the low-temperature box 4 when the positions are limited on the inner side of the bracket 1 and the side positioning plates 2.
[0026] See also Figure 4 A limiting buckle is installed on the inner side of the connection between the high-temperature box 3 and the low-temperature box 4, and the limiting buckle is sleeved on the inside of the side of the movable sleeve 9. A limiting buckle is installed on the inner side of the connection between the high-temperature box 3 and the low-temperature box 4, and the limiting buckle is sleeved on the inside of the side of the movable sleeve 9. Then the position between the movable sleeve 9 and the high-temperature box 3 and the low-temperature box 4 is spliced and limited. At the same time, the movable sleeve 9 slides on the inner side of the high-temperature box 3 and the low-temperature box 4, and then the components to be tested can be taken out. After the inner sides of the high-temperature box 3 and the low-temperature box 4 are clamped on the side of the movable sleeve 9, the movable sleeve 9 drives the position between the high-temperature box 3 and the low-temperature box 4 to be limited.
[0027] See also Figure 4The fan 6 is installed at the ends of the high temperature box 3 and the low temperature box 4. At the same time, the fan 6 is arranged outside the condensing device 7 and the heating resistor 8. By starting the condensing device 7, the condensing device 7 drives the gas circulation. At the same time, the heating resistor 8 and the movable sleeve 9 drive the generation of heat and cold air respectively, and then the high temperature box 3 and the low temperature box 4 will form a high temperature and a low temperature state respectively.
[0028] See also Figure 4 The connection between the protective plate 10 and the first circular jacket 11 is divided into two layers of space, and a heat preservation device is installed inside the two layers of space. The protective plate 10 is installed on the side of the first circular jacket 11, and the heat preservation device is installed inside the first circular jacket 11. The heat preservation device can isolate the temperature between the high-temperature box 3 and the low-temperature box 4 to avoid the problem of energy loss caused by the temperature mixing.
[0029] See also Figure 7 The protective plate 10 and the first circular jacket 11 are composed of two arc-shaped surfaces with a diameter of 90°. At the same time, the first circular jacket 11 is sleeved on the outside of the protective plate 10, and the motor 13 extends to the outside of the protective plate 10. The protective plate 10 is sleeved on the inside of the protective plate 10. By starting the motor 13, the motor 13 drives the second circular jacket 12 to rotate, and the first circular jacket 11 seals the outside of the second circular jacket 12. Then, when the position of the components placed on the upper end of the positioning plate 14 is changed for adjustment, the cold and hot air between the high-temperature box 3 and the low-temperature box 4 are prevented from blending, which leads to a decrease in the internal temperature of the high-temperature box 3 and an increase in the internal temperature of the low-temperature box 4. At the same time, the components are quickly temperature-changed, which improves the convenience of adapting to different temperatures during equipment detection.
[0030] See also Figure 6 Three groups of clamping devices 15 are installed on the outside of the positioning plate 14. The device to be detected is placed on the outside of the positioning plate 14, and the clamping device 15 is installed on the outside of the device to be detected. By placing components on the outside of the positioning plate 14 and adjusting the position of the clamping device 15, the clamping device 15 can clamp and limit the components.
[0031] Working principle: When in use, the components are placed on the upper part of the positioning plate 14, and the position of the clamping device 15 is adjusted at the same time. The clamping device 15 clamps and limits the components, pushes the protective plate 10 to move to the inside of the high temperature box 3 and the low temperature box 4, and closes the sealing plate 5, starts the condensing device 7 and the heating resistor 8, and forms the inside of the low temperature box 4 and the high temperature box 3 into a low temperature state and a high temperature state, and the high temperature and low temperature can detect the components at the same time. When the components adapt to the high temperature inside the high temperature box 3, start the clamping device 15, and the clamping device 15 drives the second circular jacket 12 to rotate. At the same time, the components inside the high temperature box 3 are flipped to the inside of the low temperature box 4, and the low temperature box 4 performs low temperature detection on the components. When the temperature is quickly changed, the internal temperature of the high temperature box 3 and the low temperature box 4 does not cause interference, thereby improving the effect of rapid conversion during component detection.
