Description

Technical Field

[0001] The invention relates to the technical field related to aluminum wire testing devices, and in particular to a corrosion resistance testing device and a corrosion-resistant aluminum wire for power devices. Background Art

[0002] The raw materials commonly used for bonding are gold, copper and aluminum. Gold wire is more expensive and is suitable for low-current products; copper wire is much cheaper than gold wire, has high mechanical strength, and has good arc stability after welding, making it suitable for high-current applications, but it is prone to oxidation, requires gas protection during the bonding process, and the bonding point is prone to cracking. IGBT is a high-power device with a large current passing through the lead, so high-purity thick aluminum wire is usually used for bonding.

[0003] At present, aluminum wires used in power devices need to be tested for corrosion resistance before use. The existing aluminum wire corrosion resistance testing device usually puts a group of aluminum wires into a corrosive solution for testing, then takes out the tested aluminum wires and puts a new group of aluminum wires into the corrosive solution for testing. However, the taking out and putting in process are mostly manual operations, which makes the testing process more complicated. In addition, if the staff are exposed to the volatile corrosive solution more, it will also cause harm to the human body. The waste residue after corrosion will adhere to the bottom surface of the inner cavity of the solution barrel.

The up and down movement of the middle cylinder 309 can drive the aluminum wire in the lower content sleeve 310 to move up and down. By controlling the up and down movement of the aluminum wire, it is convenient to perform intermittent immersion, semi-immersion and full immersion on the aluminum wire to test the corrosion resistance of different areas. After a group of aluminum wire tests are completed, Continuing to control the servo motor 317 to reverse can drive the vertical shaft 325 and the upper matching plate 328 to continue to rotate forward. The forward rotation of the upper matching plate 328 will prompt the appropriate spring 329 to tighten, and the upper drive gear 327 will stop moving, so that the middle cylinder 309 can continue to rotate forward. After the middle cylinder 309 rotates forward 180°, it can drive the aluminum wire in the upper content sleeve 310 to rotate to the bottom. At this time, the aluminum wire tested below will rotate to the top, so that it is convenient to continuously detect two groups of aluminum wires in a closed environment. Similarly, the servo motor 317 controls the side rod 308 to reverse, and the reversal of the side rod 308 can drive the upper drive gear 327 to rotate forward. The forward rotation of the upper drive gear 327 can drive the rear sealing plate 322 to move backward. When the rear sealing plate 322 When the baffle plate provided on the upper surface contacts the rear inner wall of the outer protective box 319, the outer protective box 319 is automatically opened quickly. At this time, the staff can easily replace the upper detection aluminum wire. At the same time, the vertical axis 325 is controlled to rotate forward again to cause the appropriate spring 329 to be tightened, so that the side rod 308 and the middle cylinder 309 can continue to rotate. After the middle cylinder 309 rotates 180°, the aluminum wire below can be transferred to the top. In this way, the staff can quickly replace the new aluminum wire, thereby facilitating the continuous use of the test device. When the two aluminum wires are replaced and tested, the vibration motor 330 is controlled to start. The start of the vibration motor 330 can cause the middle cylinder 309 and the inner sleeve 310 to vibrate at the same time.The vibration of the content sleeve 310 can vibrate the converted detection aluminum wire below, which can ensure that the corrosive solution is separated from the surface of the aluminum wire, effectively avoiding the waste of the corrosive solution. At the same time, when the aluminum wire after detection is moved to the top, there is less corrosive solution on its surface, which can facilitate the staff to quickly take out the aluminum wire after detection, and also avoid the corrosive solution from hurting the detection personnel;

[0053] Waste residue cleaning: First, the reduction motor 404 is controlled to start, so that the lower drive shaft 401 and the lower drive gear 411 can be driven to rotate simultaneously. The rotation of the lower drive shaft 401 can drive the inner scraper 402 and the inner stirring rod 403 to rotate simultaneously. The rotation of the inner scraper 402 can scrape the waste residue on the bottom surface of the inner cavity of the detection barrel 301, and the rotation of the inner stirring rod 403 can stir the corrosion solution, which can prevent the corrosion solution from precipitating and ensure the uniform concentration of the corrosion solution, and at the same time ensure the accuracy of the aluminum wire corrosion result. Then, the handle 408 is controlled to reverse to separate it from the surface of the detection barrel 301. At this time, pulling the handle 408 to the left can drive the inner baffle 407 to move to the left. When the inner baffle 407 When it moves to the left to the appropriate position, the transfer hole 405 is opened. The inner scraper 402 is controlled to continue to rotate to transfer the scraped waste residue through the transfer hole 405 to the collecting tank 409. After the cleaning is completed, the inner baffle 407 is pushed to the right and the handle 408 is controlled to rotate forward to quickly close the transfer hole 405. Finally, the rotation of the lower drive gear 411 can also drive the lower follower gear 412 and the lower follower rod 410 to rotate at the same time. The rotation of the lower follower rod 410 can drive the bristles 413 to rotate. The rotation of the bristles 413 can clean the waste residue on the bottom surface of the inner cavity of the collecting tank 409. At this time, the discharge port 414 can be opened to facilitate the discharge of the waste residue, thereby quickly completing the self-cleaning of the waste residue.
