Description
Technical Field
[0002] This invention specifically relates to a multi-station automated testing device for radio frequency coaxial connectors and its usage method. Background Technology
[0003] Radio frequency coaxial connectors are components that are attached to cables or installed on instruments. They serve as electrical connections or disconnections for transmission lines and are precision interfaces used to transmit high-frequency signals. They typically consist of an inner conductor, an outer conductor, and an insulating medium. The coaxial structure of radio frequency coaxial connectors can effectively reduce signal attenuation and electromagnetic interference, ensuring transmission stability. Traditional RF coaxial connector testing devices mainly rely on clamps for fixing, which usually requires manual adjustment of screws for positioning. Due to the fixed structure of the clamps and the lack of adaptive mechanisms, they often cannot clamp different types of connectors. Existing testing devices often need to be adapted according to the RF coaxial connector to be tested. Therefore, during testing, they can often only monitor a single RF coaxial connector, which is complicated and affects testing efficiency. To address this, a multi-station automated testing device for RF coaxial connectors is proposed. Summary of the Invention

[0014] The present invention also provides a technical solution, a method for using a multi-station automated testing device for radio frequency coaxial connectors, the specific steps of which are as follows: S1: First, confirm the status of each component on the workbench, check whether the electrical components of the control power supply inside the electrical control module are intact, whether the type and number of test probes on the test base match the RF coaxial connector to be tested, whether the connecting air tube of the locking component is firmly connected to the external air pump, and whether the control switch is in the off state. At the same time, according to the diameter and type of the connector to be tested, prepare the positioning sleeve with the corresponding inner diameter and the matching test base to ensure that all components are not loose or damaged. S2: If the diameter of the connector to be tested does not match the inner diameter of the current positioning sleeve, use a tool to remove the fixing screw on the side of the outer sleeve and take the old positioning sleeve out of the outer sleeve; insert the new positioning sleeve with the appropriate inner diameter into the outer sleeve, adjust it so that the top opening is tilted and the chamfer is facing upward, and then tighten the fixing screw so that the end of the screw is pressed against the outer wall of the positioning sleeve to complete the positioning sleeve fixing. Test base adjustment: If the type of connector to be tested does not match the current test probe, remove the screws connecting the base connecting plate and the bottom of the fixing plate and remove the old test base; replace it with a new test base with the corresponding type and number of test probes, align the base boss with the inner side of the bottom of the positioning sleeve and insert it, and then tighten the screws to fix the base connecting plate. If multiple types of connectors need to be tested on the same workbench, repeat the above steps to adjust the test modules of different stations. S3: Connect the external power supply to the electrical control module to ensure that the internal control power electrical components are powered; turn on the external air pump switch and check whether the air pipe is properly connected and there is no air leakage; press the control switch on the top of the workbench to test whether the electrical control module responds normally, and at the same time confirm that the detection probe is properly connected to the electrical control module through the probe wire, and the device enters the standby state. S4: Align the single set of RF coaxial connectors to be tested with the top opening of the positioning sleeve in the positioning assembly. Use the inclined chamfer inside the opening to guide the connector to be slowly inserted into the positioning sleeve until the terminals inside the connector are fully aligned with the test probes on the test base. Ensure that the terminals and probes are in close contact. If it is a multi-station test, repeat this step to install the connectors to be tested in the positioning sleeves of each station. S5: Send a clamping signal via a control switch, or directly control an external air pump to output compressed air: Compressed air enters the locking cylinder through the connecting air pipe, pushing the cylinder push rod to extend outward, causing the caliper base of the locking caliper to move towards the connector; The caliper clamp plate automatically adjusts its angle via a rotating shaft, so that the inner arc-shaped contact surface fits against the outer wall of the connector, and the anti-slip protrusions increase friction, ultimately achieving stable clamping of the connector and preventing connector displacement during the testing process; S6: Press the test start button on the control switch, and the electrical control module starts working: transmit test signals to the test probes through the probe wires, and the test probes test the electrical performance of the connectors; the test data is fed back to the electrical control module in real time through the probe wires, and the internal electrical components analyze and process the data. At the same time, the test progress and preliminary results can be viewed through the control switch or the display component of the electrical control module. S7: When the electrical control module sends a signal indicating that the test is complete, such as when the control switch indicator light changes color, press the release button. The electrical control module will then control the external air pump to depressurize, causing the locking cylinder to retract the cylinder push rod. The locking caliper will then release the connector. Hold the top of the connector by hand and remove the tested connector vertically upward from the positioning sleeve. Based on the test results, classify and place it in the qualified or unqualified area. If it is a multi-station test, remove the connectors from each station in sequence. S8: If you need to continue testing the same type of connector, you do not need to adjust the testing module. Just repeat steps S4-S7. If you need to change the testing type, return to S2 to readjust the positioning sleeve and the testing base. After the test is completed, turn off the power to the external air pump and the electrical control module, and press the control switch to cut off the main control signal of the device. If the device has a testing abnormality or clamping failure, you can remove the screws connecting the connecting bracket and the fixing plate and the electrical control module. After separating the components, repair the testing base, the electrical control module or the locking component. After the repair is completed, reassemble the connecting bracket and fix it.

A support frame is installed inside the slot. A control switch is located on the top of the worktable. A fixing plate is installed on the top of the support frame.

A positioning component is located in the center of the fixing plate. A detection base is installed at the bottom of the positioning component. A connecting bracket is installed at the bottom of the detection base. An electrical control module is installed at the bottom of the connecting bracket. Two sets of support frames are symmetrically installed on the two sides of the slot. The fixing plate overlaps the top of the support frames. Two sets of cylinder mounting shells are located on the outside of the positioning component on both sides. The cylinder mounting shells fix the locking component to the top of the fixing plate. The connecting bracket fixes the electrical control module to the bottom of the detection base. The fixing plate and cylinder... A set of detection modules is composed of a fixed shell, a locking component, a positioning component, a detection base, a connecting bracket, and an electrical control module. Several sets of detection modules are fixed side by side by a support frame. According to actual usage requirements, several sets of detection modules can be installed on the same workbench to simultaneously detect multiple sets of RF coaxial connectors. In use, the RF coaxial connector to be tested is inserted into the positioning component, so that the terminals inside the RF coaxial connector are connected to the detection base. Then, the RF coaxial connector is clamped and fixed by the locking component for testing. After the test is completed, the locking component is opened by the control switch, the RF coaxial connector is taken out, and the testing operation is completed. This simplifies the fixing operation when testing RF coaxial connectors, realizes multi-station simultaneous testing of multiple sets of RF coaxial connectors, and improves testing efficiency. 2. This invention also includes a locking caliper, comprising a caliper base, a caliper clamp plate connected to the end of the caliper base, and the caliper base being fixed to the end of the cylinder push rod. The outer side of the caliper clamp plate is connected to the caliper base via a pivot, and the inner side of the caliper clamp plate is arc-shaped with anti-slip protrusions. The connection between the caliper base and the caliper clamp plate allows the caliper clamp plate to rotate. When clamping the RF coaxial connector, the angle of the caliper clamp plate automatically changes according to the diameter of the RF coaxial connector, enabling clamping of RF coaxial connectors of different sizes. Tightening: The positioning sleeve can be removed from the outer sleeve by removing the fixing screw. Positioning of RF coaxial connectors of different diameters can be achieved by installing positioning sleeves with different inner diameters. Depending on the type of RF coaxial connector to be tested, the type and number of test probes are adjusted accordingly during testing so that the test base can be adapted to different types of RF coaxial connectors. Different types of test bases are installed on the bottom of the fixing plate on the same worktable so that the test modules at different stations on the same worktable can test different types of RF coaxial connectors.

Several sets of testing modules are installed on a workbench 1, which can simultaneously test multiple sets of RF coaxial connectors. In use, the RF coaxial connector to be tested is inserted into the positioning component 5, so that the terminals inside the RF coaxial connector are connected to the testing base 6. Then, the RF coaxial connector is clamped and fixed by the locking component 4 for testing. After the test is completed, the locking component 4 is opened by the control switch 13, the RF coaxial connector is taken out, and the testing operation is completed. This simplifies the fixing operation when testing RF coaxial connectors, realizes the simultaneous testing of multiple sets of RF coaxial connectors at multiple workstations, and improves the testing efficiency.

10. A method of using a multi-station automated testing device for RF coaxial connectors as described in any one of claims 1-9, characterized in that, S1: First, confirm the status of each component on the workbench (1), check whether the electrical components of the internal control power supply of the electrical control module (8) are intact, check whether the type and quantity of the test probes (63) on the test base (6) match the radio frequency coaxial connector to be tested, check whether the connecting air pipe (44) of the locking component (4) is firmly connected to the external air pump, check whether the control switch (13) is in the closed state, and at the same time, according to the diameter and type of the connector to be tested, prepare the positioning sleeve (52) with the corresponding inner diameter and the matching test base (6) to ensure that all components are not loose or damaged; S2: If the diameter of the connector to be tested does not match the inner diameter of the current positioning sleeve (52), use a tool to remove the fixing screw (511) on the side of the outer sleeve (51), and take the old positioning sleeve (52) out of the outer sleeve (51); insert the new positioning sleeve (52) with the appropriate inner diameter into the outer sleeve (51), adjust it so that the top opening is tilted and the chamfer is facing upward, and then tighten the fixing screw (511) so that the end of the screw is pressed against the outer wall of the positioning sleeve (52) to complete the positioning sleeve fixing. Test base adjustment: If the connector to be tested If the connector type does not match the current detection probe (63), remove the screws connecting the base connecting plate (61) and the bottom of the fixing plate (2), and remove the old detection base (6); replace it with a new detection base (6) with the corresponding type and number of detection probes (63), align the base boss (62) with the inner side of the bottom end of the positioning sleeve (52) and insert it, and then tighten the screws to fix the base connecting plate (61). If multiple types of connectors need to be tested on the same workbench (1), repeat the above steps to adjust the detection modules of different workstations. S3: Connect the external power supply of the electrical control module (8) to ensure that the internal control power electrical components are powered on; turn on the external air pump switch and check whether the connecting air pipe (44) is properly ventilated and has no leakage; press the control switch (13) on the top of the workbench (1) to test whether the electrical control module (8) responds normally, and at the same time confirm that the detection probe (63) is properly connected to the electrical control module (8) through the probe wire (64), and the device enters the standby state; S4: Align the single set of radio frequency coaxial connectors to be tested with the top opening of the positioning sleeve (52) in the positioning assembly (5), and use the inclined chamfer inside the opening to guide the connector to be slowly inserted into the positioning sleeve (52) until the terminals inside the connector are fully connected with the test probes (63) on the test base (6), ensuring that the terminals and probes are in close contact. If it is a multi-station test, repeat this step to install the connectors to be tested in the positioning sleeves (52) of each station. S5: Send a clamping signal through the control switch (13), or directly control the external air pump to output compressed air: Compressed air enters the locking cylinder (41) through the connecting air pipe (44), pushes the cylinder push rod (42) to extend outward, and drives the caliper base (431) of the locking caliper (43) to move towards the connector; The caliper clamp (432) automatically adjusts the angle through the rotating shaft, so that the inner arc-shaped contact surface fits the outer wall of the connector, and the anti-slip protrusion increases the friction, and finally achieves stable clamping of the connector to prevent the connector from shifting during the testing process; S6: Press the detection start button on the control switch (13), and the electrical control module (8) starts working: transmit the detection signal to the detection probe (63) through the probe wire (64), and the detection probe (63) detects the electrical performance of the connector; the detection data is fed back to the electrical control module (8) in real time through the probe wire (64), and the internal electrical components analyze and process the data. At the same time, the detection progress and preliminary results can be viewed through the control switch (13) or the display component of the electrical control module (8); S7: When the electrical control module (8) sends a signal indicating that the test is complete, such as when the indicator light of the control switch (13) changes color, press the release button, the electrical control module (8) controls the external air pump to depressurize, the locking cylinder (41) drives the cylinder push rod (42) to retract, and the locking caliper (43) releases the connector; pinch the top of the connector with your hand and take the tested connector vertically upward from the positioning sleeve (52), and classify it according to the test results and place it in the qualified area or unqualified area. If it is a multi-station test, take out the connectors of each station in sequence; S8: If you need to continue testing the same type of connector, you do not need to adjust the testing module. Just repeat steps S4-S7. If you need to change the testing type, return to S2 to readjust the positioning sleeve and the testing base. After the test is completed, turn off the power of the external air pump and the electrical control module (8), and press the control switch (13) to cut off the main control signal of the device. If the device has a testing abnormality or clamping failure, you can remove the screws connecting the connecting bracket (7) and the fixing plate (2) and the electrical control module (8), separate each component and repair the testing base (6), the electrical control module (8) or the locking component (4). After the repair is completed, reassemble the connecting bracket (7) and fix it.
