The platform body 35 has a rotatable clamping part 31 with a first clamp 32 and a second clamp 33. Multiple first clamps 32 and second clamps 33 are provided, and they are alternately arranged on the platform body 35. When the lifting platform 21 is in the second position, the first clamp 32 is adapted to the first test port, and the second... The clamp 33 is adapted to the second test port; the upper mold device is set on one side of the wire harness platform, and the upper mold device is provided with a third clamp and a fourth clamp. The upper mold device has a third position away from the platform body 35 and a fourth position close to the platform body 35. When the upper mold device is in the fourth position, the third clamp is adapted to the first clamp 32, and the fourth clamp is adapted to the second clamp 33; the lower mold device is set on the side of the wire harness platform away from the upper mold device and is set opposite to the upper mold device. The lower mold device is provided with a fifth clamp and a sixth clamp. The lower mold device has a fifth position away from the platform body 35 and a sixth position close to the platform body 35. When the lower mold device is in the sixth position, the fifth clamp is adapted to the first clamp 32, and the sixth clamp is adapted to the second clamp 33.

[0018] In this embodiment, the continuity tester for refrigerator wiring harnesses uses an upper mold device to position the wiring harness onto the side of the wiring harness platform. Rotating the platform body 35 allows the wiring harness to face the testing host correctly. Lowering the lifting platform 21 places both ends of the wiring harness into the first and second test ports for testing. After testing, the lifting platform 21 is raised, the platform body 35 is rotated, and then the lower mold device removes the wiring harness. Simultaneously, the upper mold device can complete the installation of the wiring harness for the next test. From the above description, it can be seen that the above embodiment of this utility model achieves the following technical effects: the continuity tester of this embodiment can simultaneously complete the installation and removal of the wiring harness, saving testing time and improving testing efficiency.

[0019] In a preferred embodiment, the wire harness platform includes a column 11 with a track on its outer surface. A hydraulic rod is installed inside the column 11, and a lifting platform 21 is connected to the free end of the hydraulic rod. The lifting platform 21 has a groove that matches the track, allowing it to move up and down on the column 11. The lifting platform 21 has a first position at a high point and a second position at a low point. An outer rail 22 is provided on the side of the lifting platform 21, running horizontally. An electric actuator 23 is also provided on the lifting platform 21, with its free end connected to a platform body 35. An inner rail that matches the outer rail 22 is provided on the platform body 35. The platform body 35 has a seventh position close to the test host and an eighth position far from the test host. A motor and a clamping part 31 connected to the free end of the motor are provided on the platform body 35, and multiple sets of clamps are provided on the clamping part 31. The clamping part 31 can be a regular geometric shape such as a ring or a square, so that the clamp after the clamping part 31 is rotated by a certain angle is in the same position as the clamp before rotation. With this configuration, the main body 35 of the wire harness platform can move in both vertical and horizontal directions, providing a high degree of freedom. Preferably, the clamping part 31 is ring-shaped or square-tube-shaped, and four sets of clamps are arranged at equal intervals around the circumference of the clamping part 31. Each set of clamps includes a first clamp 32 and a second clamp 33 for clamping the first and second ends of the test wire harness.

[0020] An upper mold device is provided on one side of the wire harness carrier to transfer the test wire harness onto the carrier. The upper mold device is equipped with a third clamp and a fourth clamp. The upper mold device has a third position away from the wire harness carrier and a fourth position closer to the carrier. When in the third position, the third and fourth clamps on the upper mold device clamp the two ends of the wire harness to be tested sent from the previous process. Then it moves to the fourth position. In the fourth position, the first clamp 32 clamps the wire harness end at the third clamp, and then the third clamp is released. The second clamp 33 clamps the wire harness end at the fourth clamp, and then the fourth clamp is released, assembling the wire harness to be tested onto the wire harness carrier. After this, the clamping part 31 rotates to align the wire harness to be tested with the test host. Then the carrier body 35 moves to insert the two ends of the wire harness to be tested into the first test port and the second test port to test the wire harness's electrical conductivity. After the test is completed, the platform body 35 rises, pulling the wire harness to be tested out of the test port. The clamping part 31 is rotated to align the tested wire harness with the lower mold device. When the lower mold device is in the sixth position, the fifth clamp clamps the wire harness end at the first clamp 32, then the first clamp 32 is released. The sixth clamp clamps the wire harness end at the second clamp 33, then the second clamp 33 is released, completing the removal of the test wire harness from the platform body 35. The lower mold device then moves to the fifth position, placing the tested wire harness into the wire harness collection area. In this embodiment, when the clamping part 31 cooperates with the upper mold device and the lower mold device, the lifting platform 21 is in the first position, and the platform body 35 is in the eighth position. When the clamping part 31 cooperates with the test host, the lifting platform 21 is in the second position, and the platform body 35 is in the seventh position. When the lifting platform 21 is in the first position and the platform body 35 is in the eighth position, the upper mold device and the lower mold device can work simultaneously, synchronously completing the installation of one wire harness to be tested and the unloading of one test wire harness, improving efficiency. Preferably, the clamping part 31 is disposed below the platform body 35, and a motor for controlling the rotation of the clamping part 31 is disposed inside the platform body 35.

[0021] In a preferred embodiment, to test various types of wire harnesses, multiple sets of test ports can be provided on the testing host. These test ports are arranged in the same column so that the movement path of the stage body 35 can cover all the test ports. The first and second test ports within each set are arranged in the same row. An identification module 34 is also provided on the clamping part 31 near the first clamp 32 or the second clamp 33 to identify the RFID tag attached to the end of the wire harness. The identification module 34 identifies the type of wire harness based on the RFID tag and sends a signal to the electric actuator to control the movement distance of the stage body 35, aligning the first clamp 32 and the second clamp 33 with the corresponding first and second test ports of the wire harness under test, thus completing the test.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
