Technical Field

[0001] The utility model relates to the technical field of electronic component detection, in particular to an electronic component temperature detection and testing device. Background Art

[0002] Temperature testing is an important step to ensure that electronic products can work normally under different temperature conditions. By simulating different temperature environments, the performance of electronic components under extreme temperatures can be tested to evaluate their quality and reliability.

[0003] However, the current testing process is difficult to control the temperature, which results in certain errors in the test results. During the test, only one component can be tested at a time, and the test efficiency is low. After the test is completed, residual heat may still remain on the inner wall of the test box, which can easily cause burns when the staff takes out the components, causing certain injuries to the staff.

[0004] For example, the electronic component temperature detection and testing device provided by publication number "CN218630009U" has a heating box and a refrigerator.

The component fixing detection assembly 3 includes a placement plate 31, which is arranged at the bottom of the detection box 21, and a power supply box 32 is fixedly mounted on one end of the top of the placement plate 31.

[0032] When the device needs to be used, first open the test box 21 through the heat-insulating handle 44, place the electronic components to be tested on the placement plates 31 in the multiple test cavities and fix them. After fixing, connect the electronic components to the power supply box 32, close the test box 21, make the multiple sealing strips 43 at the bottom of the sealing cover 4 contact with the multiple sealing partition plates 22 in the test box 21, and seal each test cavity through the multiple sealing partition plates 22 and the sealing strips 43, connect the external air source to the ventilation pipe 41 at the top of the sealing cover 4, pass hot air or cold air into each test cavity through the ventilation pipe 41, and monitor the temperature of the components during operation through the temperature detector 42;

[0033] By setting up multiple detection chambers, when in use, by placing electronic components in different detection chambers, the mutual influence between components during detection can be reduced, making the detection result more accurate. At the same time, by setting up the sealing partition plate 22 and the closing strip 43, each detection chamber can be kept relatively closed during detection to avoid mutual influence.

[0034] For example 2, please refer to Figure 1 , Figure 2 , Figure 3 Figure 4 and Figure 5 Two adjusting screws 11 are rotatably connected on one side of the interior of the fixed box 1, and both ends of the two adjusting screws 11 are rotatably connected to the top and bottom of the inner wall of the fixed box 1. The bottoms of the two adjusting screws 11 are fixedly connected to transmission wheels 12, and a transmission belt 14 is provided between the two transmission wheels 12.

[0035] When the electronic components need to be taken out of the inspection box 21 after the inspection is completed, first open the inspection box 21 through the heat-insulating handle 44, start the servo motor 13, and make the servo motor 13 drive the adjusting screw 11 to rotate. Under the transmission action of the transmission belt 14, the other adjusting screw 11 is rotated at the same time, so that the inspection box 21 moves downward along the adjusting screw 11 under the action of the fixing block 23 and the adjusting hole 24. At the same time, the fixing block 23 and the adjusting hole 24 on the other side slide downward on the sliding rod, so that the inspection box 21 moves into the fixed box 1. Since the fixing rod 36 is fixed to the bottom of the fixed box 1, when the inspection box 21 moves, the multiple component fixing detection assemblies 3 arranged in the inspection box 21 remain stationary under the action of the fixing rod 36. When the inspection box 21 is completely moved into the fixed box 1, the component fixing detection assembly 3 and the electronic components placed on the component fixing detection assembly 3 protrude from the top of the inspection box 21, which is convenient for the staff to take out the electronic components.

[0038] When placing the electronic component in the detection box 21, first pull the limit plate 34 to make the limit plate 34 slide on the placement plate 31 toward the fixing plate 33, so that the distance between the power supply box 32 and the limit plate 34 becomes larger, and the electronic component is placed on the placement plate 31 between the power supply box 32 and the limit plate 34, loosen the limit plate 34, and the limit plate 34 is driven to move toward the power supply box 32 under the action of the rebound force of the two reset springs 35, so that the limit plate 34 fixes the electronic component. After fixing, the electronic component is electrically connected to the power supply box 32, the ventilation pipe 41 is connected, and the power supply box 32 is started to detect the electronic component;

[0039] After use, when the detection box 21 moves downward, the placement plate 31 can slide on the adjustment groove 25 through the set adjustment groove 25, so that the placement plate 31 can remain stationary when the detection box 21 moves. The sealing plates set on the four sides of the adjustment groove 25 are not shown in the figure. During the detection, the gap between the adjustment groove 25 and the placement plate 31 can be sealed by the sealing plates to avoid air leakage.

[0040] Working principle: When the device needs to be used, first open the detection box 21 through the heat-insulating handle 44, pull the limit plate 34, and make the limit plate 34 slide on the placement plate 31 in the direction close to the fixing plate 33, so that the distance between the power supply box 32 and the limit plate 34 becomes larger, and the electronic components are placed on the placement plate 31 between the power supply box 32 and the limit plate 34, and the limit plate 34 is loosened. Under the action of the rebound force of the two reset springs 35, the limit plate 34 is driven to move in the direction of the power supply box 32, so that the limit plate 34 fixes the electronic components. After fixing, the electronic components are electrically connected to the power supply box 32, the ventilation pipe 41 is connected, and the power supply box 32 is started, so that the electronic components are operated at different temperatures, and the temperature of the electronic components during operation is detected by the temperature detector 42;

[0041] When the inspection is completed and the electronic components need to be taken out of the inspection box 21, first open the inspection box 21 and start the servo motor 13, so that the servo motor 13 drives the adjusting screw 11 to rotate, so that the inspection box 21 moves downward along the adjusting screw 11 under the action of the fixing block 23 and the adjusting hole 24, and at the same time, the fixing block 23 and the adjusting hole 24 on the other side slide downward on the sliding rod, so that the inspection box 21 moves into the fixed box 1. Since the fixing rod 36 is fixed to the bottom of the fixed box 1, when the inspection box 21 moves, the multiple placement plates 31 arranged in the inspection box 21 remain stationary under the action of the fixing rod 36. When the inspection box 21 is completely moved into the fixed box 1, the component fixing inspection assembly 3 and the electronic components placed on the component fixing inspection assembly 3 protrude from the top of the inspection box 21, which is convenient for the staff to take out the electronic components.
