Description

Technical Field

[0001] The utility model relates to the field of temperature sensors, in particular to a testing device for a thermal resistance type temperature sensor. Background Technique

[0002] A thermal resistance type temperature sensor is a sensor that detects temperature through the change of resistance. When the temperature changes regularly, the resistance also changes regularly, so that the temperature can be detected. However, before being put into use, it needs to be tested. Most of the existing testing devices have cumbersome operation steps and require a time interval between the detections of different sensors. Therefore, a testing device for a thermal resistance type temperature sensor is needed to replace the existing temperature sensor testing device. Content of the Utility Model

The bottom plate is slidably connected with two symmetrically arranged front and rear threaded connection blocks left and right. The threaded connection block is threadedly connected with the threaded shaft. The upper end face of the threaded connection block is fixedly connected with a fixing frame. The two fixing frames are symmetrically arranged front and rear. Each fixing frame is fixedly connected with an electric slide rail. The electric slide rail is power-connected with a slider. The electric slide rail can drive the slider to move up and down. The slider is fixedly connected with a connecting frame. The connecting frame is fixedly connected with a heat conducting sheet. And a top plate is fixedly connected between the connecting frames. The lower end face of the top plate is fixedly connected with a comparison sensor. The comparison sensor is in contact with the heat conducting sheet. The rear connecting frame is fixedly connected with a power supply. The power supply can heat up the heat conducting sheet. Thus, through the electric slide rail and the threaded shaft, the heat conducting sheet can be driven to move left and right and up and down to quickly position and prepare for testing.

[0005] The bottom plate is fixedly connected with a plurality of equidistant power connection bases left and right.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1:

[0019] Please refer to Figures 1-6 , the present invention provides a technical solution: a testing device for a thermal resistance type temperature sensor, including a bottom plate 100. The bottom plate 100 is provided with two symmetrically arranged threaded shafts 102 in the front and rear. On the left and right end faces of each threaded shaft 102, side plates 101 are fixedly connected. The side plates 101 are fixedly connected to the bottom plate 100. Two symmetrically arranged threaded connection blocks 109 are slidably connected to the left and right of the bottom plate 100. The threaded connection blocks 109 are threadedly connected to the threaded shafts 102. On the upper end faces of the threaded connection blocks 109, fixing frames 110 are fixedly connected. The two fixing frames 110 are symmetrically arranged in the front and rear. Each fixing frame 110 is fixedly connected with an electric slide rail 111. The electric slide rails 111 are all power-connected to sliders 115. The electric slide rails 111 can drive the sliders 115 to move up and down. The sliders 115 are fixedly connected with connection frames 116. The connection frames 116 are fixedly connected with heat conducting sheets 114. And between the connection frames 116, a top plate 112 is fixedly connected. On the lower end face of the top plate 112, a comparison sensor 113 is fixedly connected. The comparison sensor 113 abuts against the heat conducting sheet 114. On the rear connection frame 116, a power supply 117 is fixedly connected. The power supply 117 can heat up the heat conducting sheet 114. Thus, through the electric slide rails 111 and the threaded shafts 102, the heat conducting sheet 114 can be driven to move left and right and up and down, for rapid positioning and test preparation;

[0020] The bottom plate 100 is fixedly connected with a plurality of equidistant power connection bases 105 on the left and right. Each power connection base 105 is provided with a card slot 118. And each power connection base 105 is fixedly connected with two wiring columns 108 in the front and rear. A test sensor 106 can be clamped in each card slot 118. The test sensor 106 is connected with two connecting wires 107. The connecting wires 107 can be electrically connected to the wiring columns 108. Thus, a plurality of the test sensors 106 can be installed quickly.

[0021] On the right end face of the right side plate 101, a motor 103 is fixedly connected. The motor 103 is power-connected to the threaded shaft 102. The motor 103 can drive the threaded shaft 102 to rotate;

[0022] A smart controller 104 is fixedly connected to the front side of the upper end surface of the bottom plate 100. The smart controller 104 can receive the temperature change curves detected by the test sensors 106 and the comparison sensors 113 installed on each power connection base 105, and can control the motor 103, the power supply 117, and the electric slide rail 111.

[0023] Working principle:

[0024] First, a plurality of test sensors 106 are snap-fitted into the card slots 118 of each power connection base 105, and are connected to the terminal posts 108 on the power connection base 105 through the connecting wires 107 on the test sensors 106, so that the temperature changes of the test sensors 106 can be received by the smart controller 104, and the smart controller 104 controls the motor 103 to start. The motor 103 drives the threaded shaft 102 to rotate, the threaded shaft 102 drives the threaded connection block 109 to move, the threaded connection block 109 drives the fixed frame 110 and the electric slide rail 111 to move, thereby driving the heat conducting plate 114 to be vertically aligned with the leftmost test sensor 106, and then starting the electric slide rail 111. The electric slide rail 111 drives the connecting frame 116 to move downward, and the connecting frame 116 drives the heat conducting plate 114 to move downward, so that the lower end surface of the heat conducting plate 114 abuts against the upper end surface of the test sensor 106. Then, the power supply 117 is started to heat up the heat conducting plate 114. During the heating process of the heat conducting plate 114, the curves of the comparison sensor 113 and the test sensor 106 changing with temperature are displayed on the smart controller 104;

[0025] Then, the electric slide rail 111 drives the heat conducting plate 114 to move up to the initial position. At this time, the temperature of the heat conducting plate 114 is relatively high. Then, the motor 103 is started to drive the heat conducting plate 114 to be vertically aligned with the second test sensor 106. Subsequently, the electric slide rail 111 is started to drive the heat conducting plate 114 to move downward, so that the heat conducting plate 114 abuts against the second test sensor 106. At this time, the power supply 117 is turned off, and the temperature of the heat conducting plate 114 drops. The comparison sensor 113 and the test sensor 106 detect the curve of the temperature drop, and can also test whether the test sensor 106 meets the standard. Thus, it can be circulated in this way to test a plurality of test sensors 106 without time interval.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
