Description

Technical Field

[0001] This utility model relates to the field of thermistor wire harness detection technology, and specifically to a thermistor wire harness detector. Background Technology

[0002] Thermistors are a type of sensitive element, classified into positive temperature coefficient (PTC) thermistors and negative temperature coefficient (NTC) thermistors according to their temperature coefficient. A typical characteristic of thermistors is their sensitivity to temperature; they exhibit different resistance values ​​at different temperatures. PTC thermistors show higher resistance at higher temperatures, while NTC thermistors show lower resistance at higher temperatures. Both are semiconductor devices. Depending on the application, thermistors can also be manufactured into thermistor harnesses, forming cable assemblies with temperature detection capabilities. Thermistors require testing during the manufacturing process.

[0003] Existing thermistor harness detectors detect the thermistor harness by placing it in a heating chamber and heating it, then detecting the change in the detector's resistance. However, this method requires manual loading and unloading of the thermistor harness, resulting in low detection efficiency due to the low loading and unloading efficiency. Therefore, there is an urgent need for a thermistor harness detector to solve this problem. Utility Model Content

Limiting grooves 12 are opened at the upper end of the support plates 11 to limit the thermistor electronic wire harness. A servo motor 17 is connected to one end of the conveyor belt 10 to drive the conveyor belt 10 to rotate. A collection groove 8 is fixed directly below the conveyor belt 10 on the detection platform 1 to collect the qualified thermistor electronic wire harness. A storage drawer 9 is installed in the collection groove 8 to facilitate the cleaning of the collected wire harness. Two sets of sliding grooves 7 are symmetrically opened on both sides of the upper end of the detection platform 1. Screws 14 are installed in the sliding grooves 7. A drive motor 2 is connected to one end of the screw 14 to drive the screw 14 to rotate. A screw block 15 is sleeved on the screw 14. A conductive pinhole plate 6 is at the top of the screw block 15 to realize the conduction of the thermistor electronic wire harness circuit.

[0025] like Figures 1-4 In this embodiment, the conveyor belt 10 is rotatably installed inside the testing platform 1. The output shaft of the servo motor 17 is fixedly connected to the rotating shaft built into the conveyor belt 10. A perforated plate is installed on the testing platform 1 directly above the servo motor 17. The bearing plate 11 is bonded to the conveyor belt 10. The limiting groove 12 is formed on the bearing plate 11. The collecting groove 8 is fixed to the bottom wall of the testing platform 1 by screws. The storage drawer 9 is slidably disposed in the collecting groove 8. During use, the operator only needs to place the thermistor wire harness in the limiting groove 12 on the bearing plate 11. Then, the servo motor 17 drives the conveyor belt 10 to work and transport the thermistor wire harness to the bottom of the testing mechanism for testing. After the testing is completed, it continues to be transported and finally falls into the collecting groove 8 and storage drawer 9 by its own weight. This method can detect the continuity of the thermistor wire harness, while reducing the workload of the operator and effectively improving the testing efficiency of the device.

During the test, when the thermistor electronic wire harness is placed below the sealing cover 5 under the action of the conveyor belt 10, the drive motor 2 drives the screw 14 to rotate, causing the screw block 15 to move the conductive pin plate 6 under the action of the thread and the slide groove 7, so that it connects with the pins at both ends of the thermistor electronic wire harness, realizing the circuit conduction. At the same time, the electric push rod 4 drives the sealing cover 5 to move down to seal the limiting groove 12, and the heating plate 16 heats the thermistor electronic wire harness. At this time, the software in the computer 13 displays the change in the resistance value of the thermistor wire harness, thereby realizing the detection of the thermistor electronic wire harness.

[0027] The specific implementation process of this embodiment is as follows: The device is placed in place and connected to an external power source. During use, the operator places the thermistor wire harness in the limiting groove 12 on the support plate 11. The servo motor 17 drives the conveyor belt 10 to rotate and transport it to the bottom of the sealing cover 5. Then, the drive motor 2 drives the screw 14 to rotate, so that the screw block 15 moves the conductive pin plate 6 under the action of the thread and the sliding groove 7, so that it connects with the pins at both ends of the thermistor wire harness, realizing the circuit conduction. At the same time, the electric push rod 4 drives the sealing cover 5 to move down to seal the limiting groove 12. The heating plate 16 heats the thermistor wire harness. At this time, the software in the computer 13 displays the change in the resistance value of the thermistor wire harness, thereby realizing the detection of the thermistor wire harness.
