[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0041] The following will be described in combination with Figures 1 to 7The following describes embodiments of the present invention.
[0042] According to an embodiment of the present invention, a testing system is provided, including a test frame, a fixture 201, and a connecting unit. The test frame includes a platform 101 and a stand 102. The platform 101 is adapted to place a door lock circuit board 501 to be tested. A lifting bracket 103 capable of sliding and lifting is provided on the stand 102. The fixture 201 is fixedly connected to the lifting bracket 103. The fixture 201 is positioned above the platform 101, and the lifting bracket 103 is adapted to move the fixture 201 closer to the platform 101. The connecting unit includes a lamp board module 303, which is adapted to be electrically connected to the door lock circuit board 501. The lamp board module 303 is positioned on the stand 102. A control component is used to control the on / off state of the electrical connection between the door lock circuit board 501 and the lamp board module 303.
[0043] The testing system provided in this embodiment, through the combination of the test frame and the sliding and lifting support 103, enables flexible adjustment of the clamp 201 in vertical space to press the door lock circuit board 501 to be tested, adapting to the positioning requirements of door lock circuit boards 501 of different sizes and supporting compatibility with various door lock models. The clamp 201 and the lifting support 103 are linked to quickly fix / release the circuit board under test, shortening the test preparation time. This application uses the lamp board module 303 as the output device, and the light indication signal of the lamp board module 303 provides real-time feedback on the test results, facilitating operators to quickly judge and handle problems. Specifically, the control component uniformly manages the on / off of electrical connections, ensuring the standardization of the test process and reducing human operation errors.
[0044] In one embodiment, the extension plane of platform 101 is perpendicular to the extension plane of platform 102, and the sliding direction of lifting bracket 103 is parallel to the extension plane of platform 102. This arrangement provides stable support by vertically positioning platform 101 and platform 102, reducing mechanical vibration during sliding of lifting bracket 103 and improving structural stability. The parallel sliding of lifting bracket 103 along the plane of platform 102 ensures a linear motion trajectory for clamp 201, improving positioning accuracy and preventing poor contact due to offset.
[0045] In one embodiment, the connection unit further includes a first conductive plate 301 and a second conductive plate 302. The first conductive plate 301 is fixedly disposed on the upper surface of the platform 101 and is adapted to be electrically connected to the door lock circuit board 501. The second conductive plate 302 is fixedly connected to the lifting bracket 103. The clamp 201 is disposed on the side of the second conductive plate 302 facing the first conductive plate 301. The first conductive plate 301 is electrically connected to the lamp board module 303, and the second conductive plate 302 is electrically connected to the lamp board module 303. With this scheme, the first conductive plate 301 is fixed to the platform 101, and the second conductive plate 302 is fixed to the lifting bracket 103. The two conductive plates can form a stable double-contact electrical connection structure, reducing contact resistance fluctuations and improving the consistency of test data. The design of the second conductive plate 302 being fixedly connected to the lifting bracket 103 helps to ensure that the circuit path is the same for each test, avoiding errors caused by wiring differences and achieving the purpose of accurate measurement.
[0046] In one embodiment, the control component includes a power switch 401, which is mounted on the upper surface of the platform 101 and spaced apart from the first conductive plate 301. This design integrates the power switch 401 directly onto the platform 101, allowing the user to control the circuit's on / off state with one hand, improving testing efficiency and ease of operation. Furthermore, the power switch 401's position away from the door lock circuit board 501 where the first conductive plate 301 is located reduces the risk of accidental activation, conforms to ergonomic design, and optimizes safety during the testing phase.
[0047] In one embodiment, the test system further includes a power conversion module, which is electrically connected to the lamp board module 303. A power switch 401 is installed between the power conversion module and the lamp board module 303. This design, with its independent power supply to the power conversion module and the lamp board module 303, avoids mutual interference between the door lock circuit board 501 test and the lamp board module 303 operating voltages. It also improves power management reliability, enhances power supply stability, and improves the accuracy of the light indication signal.
[0048] In one embodiment, the control component further includes a lifting switch 402 and a solenoid valve clamping device. The lifting switch 402 is installed between the power conversion module and the solenoid valve clamping device, and the lifting bracket 103 is disposed at the transmission end of the solenoid valve clamping device. With this solution, in terms of automated control, the solenoid valve clamping device controls the clamping / releasing action of the lifting bracket 103 through the lifting switch 402, achieving rapid fixture positioning and reducing manual intervention. When testing the same model of door lock circuit board 501, the solenoid valve drive ensures consistent clamping force each time, guaranteeing test consistency and avoiding poor contact caused by uneven force application.
[0049] In a specific embodiment, two lifting switches 402 are provided. One is used to energize and control the solenoid valve pressing device to drive the lifting bracket 103 to descend, so as to implement the approach pressing action. The other is used to energize and control the solenoid valve pressing device to drive the lifting bracket 103 to rise, so as to implement the away releasing action.
[0050] In a specific embodiment, the clamp 201 is configured as a rubber pad layer. The clamp 201 may be configured as a frame structure with a clearance cavity inside to prevent the ignition switch circuit board from making conductive connections with the second conductive plate 302.
[0051] In one embodiment, the lamp board module 303 is fixedly mounted on the lifting bracket 103. This solution directly fixes the lamp board module 303 to the lifting bracket 103, reducing cable length, lowering signal transmission loss, and enhancing structural compactness; moreover, the lamp board module 303 moves synchronously with the lifting bracket 103, ensuring alignment accuracy with the circuit board.
[0052] In one embodiment, six sets of door lock circuit boards 501 and light board modules 303 are respectively provided; with this solution, the six sets of circuit boards and light board modules 303 are tested in parallel, which improves the testing efficiency and increases the production capacity; the design of multiple modules is conducive to supporting the addition or reduction of test channels according to needs, and flexibly improving the scalability of testing.
[0053] In one embodiment, the light board module 303 is equipped with LED indicator lights. These LED indicator lights provide real-time feedback on the test status, such as power-on or fault indication, enabling visual monitoring and simplifying the testing process.
[0054] In one embodiment, the test system further includes a power interface and a voltage converter, with the output side of the power interface electrically connected to the input side of the voltage converter. This approach ensures a stable DC output from the converter, reducing interference from external power fluctuations on the test system and enhancing electrical stability.
[0055] In a specific embodiment, see Figure 5 The power input is 220V, and the voltage converter establishes a 12V output, controlled by a double-row self-locking switch. (See also...) Figure 6 The 12V power supply is then controlled by the power switch 401 to power the solenoid valve and the next stage circuit, or by the lifting switch 402 to power the solenoid valve clamping device.
[0056] In one embodiment, the output voltage of the power conversion module toward the door lock circuit board 501 is set to 8V; the output voltage of the power conversion module toward the lamp board module 303 is set to 3.3V. This design ensures that the 8V output voltage matches the normal operating voltage of the door lock circuit board 501, while the 3.3V power supply meets the low-power consumption requirements of the lamp board module 303, achieving precise voltage division control. This dual-voltage design helps avoid potential damage to low-power modules from high voltage, extending the device's lifespan.
[0057] In a specific embodiment, see Figure 7 It has a 12V power input, an 8V output to power the door lock circuit board 501, and a 3.3V output to power the light board module 303.
[0058] In the above description, the circuit board to be tested is not limited to the door lock circuit board 501, but can also be used to test other circuit boards.
[0059] The testing system provided in this embodiment has the following testing steps:
[0060] 1. Place the door lock circuit board 501 to be tested on the first conductive plate 301 of the platform 101.
[0061] 2. Turn on the power switch 401. The solenoid valve clamping device starts the lifting bracket 103 to move, so as to clamp the door lock circuit board 501 and start power supply.
[0062] 3. Monitor current and voltage levels to ensure they are within the specified range.
[0063] 4. Check the high-level signal output by the 501 circuit board of the door lock. A green LED light indicates normal operation, while a red LED light indicates abnormal operation.
[0064] 5. Record the test results and generate a report.
[0065] The testing system provided in this embodiment offers a semi-automated testing method, integrating a solenoid valve clamping device and a power conversion module to ensure that each test can be completed stably and reliably; it directly uses LED indicator lights (green indicates normal, red indicates abnormal) to provide immediate result feedback, making it convenient for operators to quickly judge and handle problems.
