Technical Field

[0001] The present invention relates to the technical field of energy storage harness detection, and in particular to a detection device and a detection method for an energy storage harness. Background Art

[0002] Energy storage harnesses are wiring components that connect various electronic devices in circuits and are widely used in home appliances, computers, automobiles, aerospace, and other fields. If you want to maintain the stability of the energy storage harnesses, manufacturers will conduct electrical performance tests on the production line to ensure that each harness meets the design requirements and can maintain good electrical performance for a long time. Therefore, it is necessary to test the energy storage harnesses.

[0003] Energy storage harnesses play the role of signal and data transmission and power supply in the entire energy storage industry chain. The energy storage system requires stable and reliable signal connections, which places very strict requirements on the functionality of energy storage harnesses in terms of high temperature resistance, high voltage resistance, aging resistance, electromagnetic shielding, flame retardancy, etc. The traditional detection method is to perform a simple power-on high-voltage test on the harness after leaving the factory. Although this detection method is simple and fast, it cannot detect multiple properties of the harness body at one time. Therefore, we propose an information detection device that can detect multiple properties of the harness body at one time. Summary of the invention

[0014] A method for detecting an energy storage harness comprises the following steps:

[0015] Step 1: Before testing, make sure that the device is in the initial state. At this time, the entire flip operating table is in a horizontal state and located above the fixed base. Then, squeeze the two toggle blocks toward the middle at the same time. At this time, the two rectangular gaps are completely exposed. Then, the wiring terminals of the wiring harness body to be tested are pressed against the two rectangular gaps, and then the two toggle blocks are released. At this time, the two locking pins are pushed to both sides under the action of the tightening spring, and the wiring terminal iron of the wiring harness body is tightly pressed into the rectangular gap and tightly contacted with the electrical contact block at the bottom of the slot.

[0017] Step 3: Control the servo motor to rotate. At this time, driven by the main drive worm gear 1, the flip operating table and the thermal insulation cover are slowly flipped until the part with the wiring harness body fixed is rotated into the detection pool, that is, in a vertical state. At this time, the thermal insulation cover covers the detection pool; at this time, the internal wiring harness body can be tested for heat resistance, waterproofness, and anti-electromagnetic interference related performance.

[0018] The beneficial effects of the present invention are:

[0019] 1. By setting the heater on the side of the thermal insulation cover, when the flip operating table is flipped to the detection position during detection, the thermal insulation cover can form a fully closed state of the detection pool. At this time, the setting of the heater can make the temperature in the detection pool rise quickly, and then it can be detected whether the power-on condition of the wiring harness body is good in a high temperature environment, and whether the wiring harness body itself changes after being powered on in a high temperature environment.

[0020] 2. By setting an arc-shaped rack driven by the main drive worm gear and cooperating with a special coupling, when the flip operating table is in a horizontal state, it is only necessary to control the servo motor to cut off the power. At this time, the main drive worm gear and the transmission rod will move slightly downward under the combined action of gravity and the reverse self-locking of the worm gear, and then the bottom end of the main drive worm gear will be pressed on the upper surface of the fixed base, which increases the static friction and ensures the stability of the flip operating table. It can also make the cross-sectional area detection of the wire harness body more accurate. The cross-sectional area of ​​the wire harness determines the current carrying capacity, making the detection effect more accurate.

[0021] 3. By setting a rotating scraper rod and cooperating with the setting of the sliding clamp, the surface of the wire harness body can be pulled under extreme testing environment to detect the tensile effect of the main cable skin. BRIEF DESCRIPTION OF THE DRAWINGS
