Description

Technical Field

[0001] The present invention relates to the technical field of power component detection, and in particular to a power detection device. Background Art

[0002] Power components are now widely used, and testing them is a necessary step, including testing their energy storage performance. Therefore, they need to be tested using a testing device. Usually, a test probe connected to a tester is used to test the contact between the power component connector. The contact stability between the test probe and the power component connector, the test accuracy, and the degree of equipment integration are key factors that restrict the efficiency and reliability of the test. Traditional power testing equipment usually has the following technical bottlenecks:

[0003] 1. Existing testing equipment often uses manual positioning to achieve the docking of probes and connectors. Positioning accuracy relies on operator experience, and docking deviations can easily lead to fluctuations in contact resistance, which in turn causes distortion in the test signal. Furthermore, traditional probes lack an adaptive pressure regulation mechanism. Over long-term use, unstable contact pressure can easily cause probe wear or damage to component connectors, affecting the accuracy of test results and the lifespan of the equipment.

[0004] 2. Dust often adheres to the surface of electrical component connectors due to environmental factors. Traditional dust removal methods mostly use a single dust suction structure, which often leaves residual particles due to insufficient negative pressure, leading to poor contact or short circuit risks.

[0005] 3. Existing testing equipment typically requires multiple sets of drive devices to work together, resulting in bulky equipment, redundant structures, and a lack of linkage mechanisms between modules. This makes the operation process cumbersome and the testing efficiency limited, making it difficult to meet the needs of automated and integrated testing. Therefore, it is necessary to design a power testing device. Summary of the Invention

When the power element 4 connector contacts the positioning guide plate 13, the positioning guide plate 13 can be squeezed to make the positioning guide plate 13 move automatically, and then the position of the positioning guide plate 13 can automatically adapt to the power element 4 connectors of different widths, and the applicability is better.

[0035] A dust collection hood 40 and a dust blowing hood 41 are fixed inside the device cylinder 30. The dust collection hood 40 is located above the dust blowing hood 41.

A one-way air outlet valve 8 connected to the second sliding plug cavity 20 is provided on the right side wall of the device plate 6. The gas inside the second sliding plug cavity 20 can be discharged from the one-way air outlet valve 8. 8 one-way discharge, a first sliding plug rod 21 and a second sliding plug rod 22 are fixed on the left and right side walls of the device seat 12 respectively, and the first sliding plug rod 21 and the second sliding plug rod 22 are slidably inserted into the first sliding plug cavity 19 and the second sliding plug cavity 20 respectively. The lower end of the device plate 6 is provided with a first bellows 16 connected to the first sliding plug cavity 19, and the first bellows 16 is connected to the second connecting pipe 28. A one-way valve is provided inside the first bellows 16, so that the first sliding plug cavity 19 unidirectionally guides air to the second connecting pipe 28 through the first bellows 16. The lower end of the device plate 6 is provided with an intake pipe 10 connected to the second sliding plug cavity 20, and a one-way valve is provided inside the intake pipe 10, so that the intake pipe 10 can only guide air unidirectionally to the second sliding plug cavity 20. The lower end of the device plate 6 is provided with a dust filter structure connected to the intake pipe 10 and the first connecting pipe 27.

[0036] The dust filtering structure includes a connecting sleeve 18 fixed to the lower end of the device plate 6, and a second bellows 17 is connected to the side wall of the connecting sleeve 18, and the second bellows 17 is connected to the first connecting pipe 27.

Since the collecting box 11 is screwed to the connecting sleeve 18, the collecting box 11 can be easily disassembled and assembled, so that the dust filter mesh cylinder 23 can be directly taken out for cleaning or replacement.

[0037] When the device seat 12 moves to the left in the movable groove 14, it drives the first sliding plug rod 21 and the second sliding plug rod 22 to move to the left, thereby generating a positive pressure inside the first sliding plug cavity 19, pumping air into the dust blowing hood 41 through the first bellows 16 and the second connecting pipe 28, and then blowing air to the connector of the power element 4 through the dust blowing hood 41, so as to achieve the dust blowing operation on the connector of the power element 4, and at the same time generate a negative pressure inside the second sliding plug cavity 20, sucking from the dust hood 40 through the second bellows 17 and the first connecting pipe 27, and then vacuuming the area around the connector of the power element 4 through the dust hood 40, so that the dust on the connector of the power element 4 can be fully blown away from the connector, and then the dust is sucked away in time, so as to achieve the effect of sufficient dust blowing and timely dust suction, and the dust removal efficiency and dust removal effect are significantly improved.

[0038] When the present invention is used, the power component 4 to be tested is placed inside the placement table 3, and the placement table 3 is moved by the conveyor belt 2, thereby driving the power component 4 to move forward. When the power component 4 moves, its joint contacts the positioning guide plate 13, pushing the positioning guide plate 13 to move. The positioning guide plate 13 drives the moving seat 24 to slide on the guide rod 25 through the vertical rod 31, and at the same time compresses the first spring 26. At this time, the second electric telescopic rod 32 starts to extend, pushing the vertical rod 31 downward, so that the positioning guide plate 13 presses the joint of the power component 4, thereby achieving precise positioning;

[0039] The second spring 38 is used to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the second spring 39 to push the

[0040] Then, the third electric telescopic rod 34 continues to push the device tube 30 downward, so that the detection probe 39 contacts the connector of the power element 4, and the pressure sensor 35 monitors the contact pressure in real time. When the pressure is insufficient, the third electric telescopic rod 34 continues to press down until the set pressure value is reached. At this time, the detection probe 39 is connected to the connector of the power element 4 to complete the detection process of the power element 4, and the cleaning and dust removal processes and the detection processes are carried out during the movement of the power element 4, thereby effectively improving the detection efficiency. After the detection is completed, the detected power element 4 is sent out to the left side of the conveyor belt 2, and the second electric telescopic rod 32 is started to retract, driving the vertical rod 31 to move upward, driving the positioning guide plate 13 to leave the connector of the power element 4, and at the same time starting the third electric telescopic rod 34 to retract, driving the device tube 30 to move upward, and then starting the first electric telescopic rod 9 to retract, driving the device seat 12 to move and reset, and the conveyor belt 2 continues to transport the next power element 4 forward for detection, repeating the above process to complete the continuous detection of the power element 4.
