Description

Technical Field

[0001] This utility model relates to the field of FPC line impedance testing technology, specifically to an intelligent device for automatic acquisition and determination of FPC line impedance. Background Technology

[0002] A stable loop resistance in an FPC ensures the stability of parameters such as current and voltage, enabling the FPC to operate according to design standards and avoiding performance degradation due to resistance fluctuations. This also facilitates better collaboration between the FPC and other electronic components, ensuring battery pack performance and reducing circuit failures caused by resistance fluctuations.

[0003] Testing the resistance of FPCs is particularly important, especially since the impact of simulated harsh environment experiments on the circuit resistance is immeasurable. Traditional circuit resistance testing devices apply a known DC current to the circuit under test, measure the voltage across the circuit, calculate the resistance value according to Ohm's law and display it on the instrument, and then manually record the test data before testing another circuit. This process is time-consuming, and each test can only be performed at a single point. In mass production in factories, this results in long testing periods, increased labor and equipment investment costs, and low testing efficiency, making it unsuitable for the needs of factory production. Therefore, we propose an intelligent device for automatic acquisition and judgment of FPC line impedance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent device for automatic acquisition and judgment of FPC line impedance. It solves the problems of measuring the voltage generated at both ends of the circuit, calculating the resistance value according to Ohm's law and displaying it on the instrument, and then manually recording the test data and then testing another circuit, which is time-consuming. In addition, each test can only be conducted at a single point. In mass production in the factory, the test period is long, the labor and equipment investment costs are increased, the test efficiency is low, and it is not suitable for the needs of factory production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent device for automatic acquisition and determination of FPC line impedance, comprising a test platform, a DC resistor, a test meter, a USB converter, and a test sample. The DC resistor and the USB converter are placed on the test platform and connected via a data cable. The test meter is plugged into the DC resistor. A limiting unit is provided on the test platform, and the test sample is located within the limiting unit.

[0006] The limiting unit includes a fixed base and a clamping base. The fixed base is fixedly connected to the test platform, and a connecting base is fixedly connected to the outer wall of the fixed base. The clamping base is slidably connected to the inner wall of the connecting base, and the test sample is located between the fixed base and the clamping base.

[0007] Preferably, the test meter is equipped with a membrane switch, which is connected to a USB converter via a data cable.

[0008] Preferably, the USB converter connects the DC resistor to the PC via data transfer.

[0009] Preferably, a connecting rod is fixedly connected to the inner wall of the connecting seat.

[0010] Preferably, a sliding block is slidably connected to the outer peripheral wall of the connecting rod, and the top end face of the sliding block is fixedly connected to the clamping seat.

[0011] Preferably, a spring is sleeved on the outer peripheral wall of the connecting rod.

[0012] Preferably, the two sides of the spring are fixedly connected to the sliding block and the connecting seat, respectively.

[0013] This utility model discloses an intelligent device for automatic acquisition and determination of FPC line impedance, which has the following beneficial effects:

[0014] Turn on the DC resistor, set the condition parameters, turn on the computer, and set the software; connect the test meter to the terminals of the test sample to perform a circuit test; once the DC resistor data stabilizes, press the membrane switch. By setting the membrane switch, automatic data acquisition is achieved, reducing manual back-and-forth writing, improving testing efficiency, reducing testing difficulty, and avoiding data recording on paper, thus avoiding paper waste and recording errors. By placing the test sample between the fixing base and the clamping base, the test sample is fixed, making it easy for the test meter to contact the corresponding terminals on the test sample, facilitating multi-point testing and effectively avoiding the slow efficiency of single-point testing.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides an intelligent device for automatic acquisition and judgment of FPC line impedance. It solves the problems of measuring the voltage across the circuit, calculating the resistance value based on Ohm's law and displaying it on the instrument, then manually recording the test data and testing another circuit – a time-consuming process that only allows for single-point testing. In mass production, this results in long testing periods, increased labor and equipment investment costs, and low testing efficiency, making it unsuitable for factory production needs. The device automatically acquires data by opening the DC resistor 2, setting condition parameters, turning on the computer, and configuring the software. The test meter 3 is then contacted with the terminals of the test sample 6 to perform circuit testing. Once the DC resistor 2 data stabilizes, the membrane switch 4 is pressed. By setting the membrane switch 4, automatic data acquisition is achieved, reducing manual back-and-forth writing, improving testing efficiency, and lowering the difficulty of testing. It also avoids paper-based data recording, preventing paper waste and errors. By placing the test sample 6 between the fixing base 701 and the clamping base 702, the test sample 6 is fixed, facilitating contact between the test meter 3 and the corresponding terminals on the test sample 6 for multi-point testing, effectively avoiding the slow efficiency of single-point testing.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This utility model discloses an intelligent device for automatic acquisition and determination of FPC line impedance.

[0024] According to the appendix Figure 1-3As shown, the test includes a test platform 1, a DC resistor 2, a test meter 3, a USB converter 5, and a test sample 6. The DC resistor 2 and the USB converter 5 are placed on the test platform 1 and connected by a data cable. The test meter 3 is plugged into the DC resistor 2. A limiting unit 7 is provided on the test platform 1, and the test sample 6 is located in the limiting unit 7.

[0025] After placing the test sample 6, turn on the DC resistor 2, set the condition parameters, turn on the computer, and set the software; connect the test meter 3 to the terminals of the test sample 6 respectively to perform a circuit test; after the DC resistor 2 data stabilizes, press the membrane switch 4 to control the computer to collect the DC resistor 2 data through the USB converter 5, and output the data report. By automating the acquisition and storage of data sources, the difficulty of testing is reduced, and data recording on paper is avoided, thus avoiding paper waste and recording errors.

[0026] The limiting unit 7 includes a fixing base 701 and a clamping base 702. The fixing base 701 is fixedly connected to the test platform 1. A connecting base 703 is fixedly connected to the outer wall of the fixing base 701. The clamping base 702 is slidably connected to the inner wall of the connecting base 703. The test sample 6 is located between the fixing base 701 and the clamping base 702. By placing the test sample 6 between the fixing base 701 and the clamping base 702, the test sample 6 is fixed, which facilitates contact between the test meter 3 and the corresponding terminal on the test sample 6, making it convenient to perform multi-point testing and effectively avoiding the situation where single-point testing is slow.

[0027] The test meter 3 is equipped with a membrane switch 4, which is connected to the USB converter 5 via a data cable. By setting the membrane switch 4, automatic data acquisition can be achieved, reducing manual back-and-forth writing and improving testing efficiency.

[0028] USB converter 5 connects DC resistor 2 to the PC via data transmission. The computer software analyzes and judges the data, and outputs a report. By automatically collecting and saving data sources, the difficulty of detection is reduced, and data recording on paper is avoided, thus preventing paper waste and recording errors.

[0029] A connecting rod 704 is fixedly connected to the inner wall of the connecting seat 703.

[0030] A sliding block 706 is slidably connected to the outer peripheral wall of the connecting rod 704. The top end face of the sliding block 706 is fixedly connected to the clamping seat 702. The sliding block 706 slides on the outer peripheral wall of the connecting rod 704, making the movement of the sliding block 706 and the clamping seat 702 more stable.

[0031] A spring 705 is sleeved on the outer peripheral wall of the connecting rod 704.

[0032] The two sides of the spring 705 are fixedly connected to the sliding block 706 and the connecting seat 703, respectively. By pulling the clamping seat 702 and the sliding block 706, the spring 705 is stretched by the movement of the sliding block 706. The test sample 6 is then placed between the fixed seat 701 and the clamping seat 702. When the clamping seat 702 is released, the clamping seat 702 moves towards the fixed seat 701 under the rebound of the spring 705, clamping and fixing the test sample 6. This facilitates contact between the test meter 3 and the terminals of the test sample 6 for testing.
