Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, specifically to a temperature function testing device for circuit boards. Background Technology

[0002] With the continuous development and popularization of modern electronic technology, electronic products have permeated all aspects of our lives. The most important part of electronic products is the circuit board, which is equipped with a variety of pins and circuit components. Before its production and subsequent use, it is necessary to test the power supply and operating temperature of its internal circuits.

[0003] A search revealed that patent application number 202321858300.4 discloses a temperature function detection device for circuit boards, comprising an adjustment structure and a connection structure. The adjustment structure is connected to the circuit board to be tested via the connection structure. The adjustment structure includes a level plate, a detection element, and a screw mechanism. The detection element has multiple continuously adjustable levels. The level plate is located above the detection element, and has a level adjustment hole in the center. The screw mechanism passes through the level adjustment hole, and has multiple corresponding resistance and temperature display structures around its perimeter. This invention overcomes the shortcomings of existing temperature function detection devices, which are large, bulky, and difficult to move, making temperature function detection of circuit boards more convenient and efficient.

[0004] In existing circuit board temperature detection technologies, some patent applications employ resistive components to achieve temperature detection. The principle is to utilize the heat generated by current flowing through a resistor, causing the resistor's temperature to rise and exchange heat with the circuit board. The temperature of the circuit board is then indirectly reflected by detecting the change in the resistor's resistance. However, this technology has significant drawbacks: firstly, the resistor needs to undergo a process of current loading, heat generation, heat transfer to the circuit board, and temperature stabilization, making the entire detection cycle lengthy; secondly, because the resistor needs time to accumulate heat and complete heat transfer, the detection efficiency is low, making it difficult to meet the application requirements for rapid, real-time circuit board temperature detection. This limits the application of this technology in scenarios with high response speed requirements, such as industrial automation and data center temperature control.

[0005] Therefore, we propose a temperature function detection device for circuit boards. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a temperature function detection device for circuit boards, which solves the problem of low temperature detection efficiency in existing resistive circuit boards.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a temperature function detection device for a circuit board, including a detection base, on which a circuit board to be tested is placed, and a connector wire electrically connected to the circuit board is provided on the detection base;

[0008] The top side of the detection seat is provided with two sets of sliding columns, and an infrared temperature measuring component is slidably fitted between the two sets of sliding columns. The infrared temperature measuring component is provided with a sliding sleeve that matches the specifications of the sliding columns.

[0009] The infrared temperature measurement component includes an infrared detector and an optical lens assembly at its bottom. A top frame is fixedly installed on the top of the infrared detector, and a temperature display that plays the temperature in real time is also provided on the top side of the infrared detector.

[0010] As a preferred embodiment of this utility model, four sets of L-shaped top frames are fixedly installed at the four corners of the top of the detection seat, and sliding columns are fixedly connected between the front and rear sets of top frames.

[0011] The top frame provides an installation position for the sliding column, ensuring the stability of the sliding column and the infrared temperature measurement components mounted on it.

[0012] As a preferred embodiment of this utility model, a cylinder assembly is fixedly installed on the inner side of the sliding column, a support plate is provided at the bottom of the infrared temperature measuring assembly, and the outer end of the sliding column output shaft is fixedly connected to the outer wall of the support plate.

[0013] The cylinder assembly facilitates the adjustment of the infrared temperature measurement component to move back and forth on the circuit board under test, thereby enabling real-time temperature detection at various locations on the circuit board and ensuring effective temperature detection.

[0014] As a preferred embodiment of the present invention, the optical lens assembly includes a lens assembly and a reflector assembly. The optical lens assembly is disposed on the top side of the circuit board under test, and the output end of the optical lens assembly is disposed on the input end of the infrared detector.

[0015] The optical lens assembly is responsible for collecting and focusing the infrared radiation emitted by the object being measured. It consists of optical elements such as lenses and mirrors and can converge the infrared light emitted by the target object onto the infrared detector to ensure that as much infrared radiation as possible is received by the infrared detector, thereby improving the accuracy of the measurement.

[0016] In a preferred embodiment of this utility model, the infrared detector is a thermistor type, and the infrared detector converts the infrared energy output by the optical lens assembly into an electrical signal and sends it to the signal processing circuit converter.

[0017] When the converged infrared radiation shines on the infrared detector, the detector absorbs the infrared energy and converts it into a corresponding electrical signal. The detector's temperature rises due to the absorption of infrared radiation, causing a change in its resistance. By measuring the change in resistance, an electrical signal related to the intensity of infrared radiation can be obtained. Simultaneously, the optical lens assembly amplifies, filters, and linearizes the electrical signal output from the optical lens assembly, converting it into a digital signal corresponding to the temperature of the object being measured. During this process, the electrical signal is precisely calculated and converted according to the calibration parameters of the infrared temperature measurement component and related algorithms to eliminate the influence of various interference factors and improve measurement accuracy.

[0018] As a preferred embodiment of this utility model, the signal processing circuit converter converts the electrical signal output by the optical lens assembly into a digital signal, and the temperature display includes a liquid crystal display screen that receives digital signals.

[0019] Among them, the temperature display can convert digital signals into intuitive temperature values ​​and display them. It may also provide other information, such as measurement units and temperature alarm prompts, so that users can read and understand the temperature of the object being measured.

[0020] This invention provides a temperature detection device for circuit boards. It has the following advantages:

[0021] This temperature detection device for circuit boards, through the setting of the infrared temperature measuring component structure, can perform real-time temperature detection on the bottom side of the circuit board under test using infrared detection, which is highly efficient. At the same time, the setting of the cylinder component can adjust the lateral movement of the infrared temperature measuring component on the circuit board, ensuring efficient temperature detection at various positions on the circuit board, thus solving the problem of low temperature detection efficiency of existing resistive circuit boards.

At the same time, the setting of the cylinder component 6 can adjust the horizontal movement of the infrared temperature measuring component 5 on the circuit board, ensuring efficient temperature detection at various positions on the circuit board, thus solving the problem of low temperature detection efficiency of existing resistive circuit boards.

[0030] Example 2:
