Description

Technical Field

[0001] The invention relates to the technical field of corrosion resistance detection, and in particular to a corrosion resistance detection device and a detection method for automobile interior decoration materials. Background Art

[0002] With the increasing requirements for product quality, salt spray corrosion resistance has gradually received high attention as an important indicator for evaluating materials and their protective layers. In particular, automotive interior materials are in direct contact with drivers and passengers, and are in a relatively closed space inside the car that may be exposed to a variety of environmental factors. Therefore, there are high requirements for their corrosion resistance. At present, when conducting corrosion resistance tests on automotive interior materials, salt spray test devices are usually used for testing. However, after completing the test, the current salt spray test device needs to transfer the sample to another place for cleaning and drying before it can be observed and weighed to evaluate the results. This leads to secondary contamination or influence of the external environment on the sample due to operator errors during the sample transfer process, resulting in inaccurate test results.

[0056] A connecting plate 34 is fixedly installed at one end of the auxiliary electric push rod 35, a sliding rod 31 is fixedly installed on the front of the connecting plate 34, one end of the sliding rod 31 is slidably installed in the test box 1, and a guide plate 32 is fixedly installed on the top of the sliding rod 31 on one side inside the test box 1, a fixed block 33 is slidably installed in the guide plate 32, and one end of the fixed block 33 is inclined and slidably installed in the positioning hole

[0057] A fixing frame 37 is fixedly installed in the test box 1, a switching rod 36 is fixedly installed on the fixing frame 37, the switching rod 36 is adapted to the size of the switching hole, an air storage bag 38 is fixedly installed on the fixing frame 37, an air pipe 39 is fixedly installed in the switching rod 36, the air storage bag 38 is connected to the elastic air bag 310 through the air pipe 39, and the elastic air bag 310 is adapted to the size of the positioning hole.

[0058] When in use, by rotating the threaded rod 211, the threaded rod 211 and the clamping rod 212 are threadedly matched, and the clamping rod 212 and the fixed seat 210 are slidably matched, so that the clamping rod 212 can move linearly along the fixed seat 210 under the drive of the threaded rod 211, and the material plate 29 is clamped on the hanging rack 27 through the matching between the clamping rod 212 and the fixed seat 210, and then the hanging rack 27 is slid onto the support block 28 to close the box cover 16;

[0059] After closing the box cover 16, the partition plate 25 is placed in the sliding hole opened at the top of the box cover 16 and then the feed pump 13 is started. A closed inner cavity is formed between the partition plate 25, the scraper 26 and the box cover 16 to prevent the salt mist from escaping from the sliding hole. At the same time, when the partition plate 25 moves upward, the scraper 26 can scrape off the salt mist attached to the surface of the partition plate 25, and the partition plate 25 provides a supporting force to the support rod 22. One end of the support rod 22 is inserted into the support plate 21, and the support rod 22 provides a supporting force to the reinforcing plate 23. The reinforcing plate 23 and the fixing pin 24 are slidably matched. The support rod 22 and the support plate 21 are combined by the fixing pin 24, and the main electric push rod 2 provides a supporting force to the support plate 21;

[0060] When the material plate 29 reaches the set salt spray test time, the switching program is entered, and the main electric push rod 2 is controlled to start through the console 11, and the support plate 21 is driven to move up through the main electric push rod 2, and the support plate 21 drives the partition plate 25 to move up through the fixing pin 24, the reinforcing plate 23, and the support rod 22. At the same time, the auxiliary electric push rod 35 is controlled to start through the console 11, and the connecting plate 34 is driven to move through the auxiliary electric push rod 35, and the sliding rod 31 is driven to move through the connecting plate 34. The sliding rod 31 drives the guide plate 32 and the fixed block 33 to move synchronously, so that the sliding rod 31 moves to the side where the switching sleeve 3 is located, until the switching sleeve 3 is stuck in the sliding rod 31. At this time The switching sleeve 3 will first contact the inclined end of the fixing block 33 and squeeze the fixing block 33 to move upward. The fixing block 33 and the guide plate 32 slide together so that the fixing block 33 only moves in a straight line when moving. When the switching sleeve 3 is completely inserted into the sliding rod 31, the fixing block 33 falls down due to its own gravity and is inserted into the switching sleeve 3, so that the sliding rod 31 and the switching sleeve 3 are combined together. At this time, the auxiliary electric push rod 35 continues to move and drives the material hanging rack 27 to move through the switching sleeve 3, so that the material hanging rack 27 slides out from the supporting block 28, and the partition plate 25 also moves upward under the action of the main electric push rod 2, so that the material hanging rack 27 with the material plate 29 can enter the cleaning area.

[0061] As the hanger 27 moves, the switching rod 36 is inserted from the other side of the hanger 27 and penetrates into the switching sleeve 3, and the switching rod 36 squeezes the fixed block 33 to move upward again. At the same time, the hanger 27 squeezes the air storage bag 38 installed on the fixed frame 37, so that the gas in the air storage bag 38 is transported to the elastic air bag 310 through the air pipe 39, so that the elastic air bag 310 expands upward from the switching rod 36. In the process of the elastic air bag 310 expanding upward, the fixed block 33 is completely squeezed out of the sliding rod 31 and replaced by the fixed block 33 in the switching sleeve 3, so that the switching sleeve 3 and the sliding rod 31 are no longer combined together but combined with the switching rod 36;

[0062] At this time, the main electric push rod 2 and the auxiliary electric push rod 35 are both moved to the maximum distance, and the control console 11 controls the main electric push rod 2 and the auxiliary electric push rod 35 to reset to the initial position, and the main electric push rod 2 drives the partition plate 25 to fall again to separate the test area from the cleaning area. At this time, the water pump can be controlled by the control console 11 to start, and the water in the water storage tank 5 is transported to the cleaning area through the water pump, and sprayed out through the clean water nozzle 51 after being atomized, and the material plate 29 is cleaned by the atomized clean water;

[0063] After the material plate 29 is cleaned, the fixing pin 24 is pulled out, and the support plate 21 is rotated 180° with the main electric push rod 2 as the axis, and the box cover 16 is opened. By opening the one-way air outlet valve, the gas in the elastic air bag 310 passes through the air pipe 39 and the air storage bag 38 and finally flows out from the one-way air outlet valve. At this time, the cleaned material plate 29 can be taken out, and after drying, it can be observed and weighed to obtain the test result.

[0067] At the same time, the airflow driven by the fan 41 will drive the fan blades 43 to rotate around the support shaft 42 as the axis. The support shaft 42 will drive the push rod 44 to rotate during the synchronous rotation. The push rod 44 squeezes the power rod 45 to move. The power rod 45 and the guide rod 1 47 slide together, so that the power rod 45 only moves in a straight line.
