A first test machine 700 is mounted within the first test station 103, and a test connection of the first test machine 700 is mounted on the first lifting fixture 800. A blanking module 900 is mounted within the discharge station 104. Wherein the wire harness is transported into the first test station 103 by a transport fixture 300 located at the loading station 102, and a first lifting fixture 800 removes the wire harness from the transport fixture 300 and inserts it into a test connection of the first test machine 700. The initial position of the conveying fixture 300 is located at the charging station 102 and the first testing station 103, the transmission module 200 conveys the wire harness located in the charging station 102 into the first testing station 103, and the transmission module 200 conveys the wire harness located in the first testing station 103 into the discharging station 104.
When the wire harness is used, the wire harness is fixed in the locating port 501 of the locating clamp 500 by manpower, the lifting charging module 400 drives the wire harness to move, the wire harness is close to the conveying clamp 300, the conveying clamp 300 takes the wire harness out of the locating port 501, and the wire harness is conveyed into the first test station 103 through the transmission module 200. After the wire harness is transferred into the first test station 103, the first lifting fixture 800 fixes the wire harness and inserts both ends of the wire harness into the test connector of the first tester 700. The sway testing module 600 then clamps the wire harness to sway, and the first testing machine 700 tests the electrical connection of the wire harness during sway.

The fixed end of the lifting adjusting component 302 is arranged on the sliding table connecting base 301; a mounting bar 303 is horizontally mounted on the movable end of the elevation adjustment assembly 302. At least two finger cylinders 304 are mounted on the mounting bar 303. The two movable ends of the finger cylinder 304 are respectively provided with the clamping pieces 305, and a clamping opening 306 for clamping the wire harness is formed between the two clamping pieces 305. When the finger cylinder 304 at the loading station 102 drives the clamping member 305 to close to fix the wire harness in the clamping opening 306, the lifting loading module 400 moves to disengage the wire harness from the positioning opening 501 of the positioning clamp 500, and the transmission module 200 moves to convey the wire harness to the first testing station 103 for detection; after the first lifting fixture 800 located in the first test station 103 fixes the wire harness on the clamping piece 305, the clamping piece 305 is opened, and the lifting adjustment assembly 302 drives the finger cylinder 304 to descend and reset, so that the finger cylinder 304 located in the charging station 102 is always located in the charging station 102.
In use, since the slide table connection base 301 is mounted on the slide table 202, the slide table connection base 301 mounted on the slide table 202 is driven to move when the long-stroke cylinder drives the slide table 202 to move. After the conveying clamp 300 is conveyed to a specified position by the air cylinder, the wire harness is fixed by other clamps on the station, the finger air cylinder 304 controls the clamping piece 305 to be opened, and the lifting adjusting assembly 302 arranged on the sliding table connecting base 301 moves to drive the finger air cylinder 304 to descend for abdication. And then the conveying fixture 300 is driven by the air cylinder to reset. The lifting adjusting assembly 302 drives the finger cylinder 304 to give way, so that the clamping piece 305 and the wire harness are prevented from being interfered when reset, and defective products caused by the fact that the wire harness is pulled are avoided.
