Description

Technical Field

[0001] The present invention relates to the technical field of TOM diaphragm testing, and in particular to a weather resistance testing device for automobile TOM diaphragm production. Background Art

[0002] TOM diaphragms are key materials in the field of automotive parts, and their performance directly affects the safety and reliability of the whole vehicle. In order to ensure that TOM diaphragms can work properly under various complex climate conditions, weather resistance tests are carried out on TOM diaphragms. Such tests include salt spray tests, ultraviolet irradiation tests, and temperature and humidity change tests, etc. These tests can simulate the usage scenarios under different environmental conditions, so as to evaluate the corrosion resistance, anti-aging ability and the ability to adapt to extreme climates of TOM diaphragms.

[0003] At present, most of the weather resistance testing equipment on the market is designed with a single function. For example, salt spray testing equipment can only perform salt spray corrosion tests, ultraviolet testing equipment can only provide ultraviolet light simulation, and temperature and humidity change tests require another set of independent equipment to complete. When conducting multiple tests, it is necessary to frequently transfer the TOM diaphragm from one device to another, which will increase the workload of the staff, and each transfer is accompanied by potential risks and is easily interfered by the outside world, such as sample contamination or damage, affecting the accuracy of the test results.

[0032] Refer to Figure 6 , Figure 7 and Figure 10, the feeding mechanism includes a lead screw motor 19, a moving block 20, a first electric conveying roller 21 and a first driven conveying roller 22. The lead screw motors 19 are installed on both the front and rear sides inside the box body 1. The moving blocks 20 are connected to the lead screws of the lead screw motors 19 through threads. The first electric conveying roller 21 is jointly installed on the upper parts of the two moving blocks 20, and the first driven conveying roller 22 is jointly rotatably connected to the middle parts of the two moving blocks 20. The first electric conveying roller 21 and the first driven conveying roller 22 are driven by gears. A feeding port 23 is opened in the middle of the right side of the box body 1.

[0033] Referring to Figures 6-8 , the supporting mechanism includes a cross plate 24, a sliding rod 25, a supporting plate 26 and a spring 27. The cross plate 24 is connected to the middle part inside the box body 1 by bolts. The sliding rods 25 are symmetrically slidably connected to the front and rear sides of the left and right sides of the top of the cross plate 24. The upper ends of the four sliding rods 25 are jointly connected to the supporting plate 26. The left and right sides of the supporting plate 26 are inclined downward. Springs 27 are sleeved on the sliding rods 25. The two ends of the springs 27 are respectively connected to the cross plate 24 and the supporting plate 26. The springs 27 are sleeved on the sliding rods 25, which can prevent the springs 27 from bending.

[0034] Referring to Figure 9 and Figure 10 , the discharging mechanism includes a fixed block 28, a second electric conveying roller 29 and a second driven conveying roller 30. The fixed blocks 28 are connected to the front and rear sides on the left side of the box body 1 by bolts.

The second electric conveying roller 29 and the second driven conveying roller 30 are driven by gears. A discharging port 31 is opened in the middle of the left side of the box body 1.

[0035] Referring to Figure 6 , the photographing mechanism includes a material receiving plate 32, a mounting plate 33 and a vision camera 34. The material receiving plate 32 is connected to the middle part on the left side of the box body 1 by bolts. The mounting plate 33 is connected to the upper part on the left side of the box body 1 by bolts. The vision camera 34 is installed on the bottom left side of the mounting plate 33 by bolts.

[0036] The staff controls the electric guide rail 3 to drive the connecting frame 4 to move upward. The connecting frame 4 drives the cylinder 5 to move upward, moving the cylinder 5 away to make room for the TOM diaphragm. Then, the TOM diaphragm is extended between the first electric conveying roller 21 and the first driven conveying roller 22 through the feed port 23. Next, the lead screw motor 19 is controlled to drive the moving block 20 to move leftward. The moving block 20 drives the first electric conveying roller 21 and the first driven conveying roller 22 to move leftward. The first driven conveying roller 22 contacts the inclined position on the right side of the supporting plate 26 and pushes the supporting plate 26 downward. The spring 27 is compressed. The first electric conveying roller 21 and the first driven conveying roller 22 pull the TOM diaphragm leftward, pulling the TOM diaphragm to the lower part of the cylinder 5. When the first driven conveying roller 22 and the supporting plate 26 are disengaged, under the action of the spring 27, the supporting plate 26 moves upward. The supporting plate 26 can support the TOM diaphragm. Subsequently, the electric guide rail 3 is controlled to drive the connecting frame 4 to move downward. The connecting frame 4 drives the cylinder 5 to move downward, making the cylinder 5 contact the TOM diaphragm. The hard tube 15 can be externally connected to brine. The solenoid valve 16 is controlled to open. The brine flows into the hose 14 through the hard tube 15 and into the n-shaped tube 12 through the hose 14. Finally, the brine is sprayed out through the atomizing nozzle 13 and sprayed onto the TOM diaphragm for salt spray testing. Water can also be externally connected to the water pipe 17. The solenoid valve 18 is controlled to open. The clear water flows into the hose 14 through the hard tube 15 and into the n-shaped tube 12 through the hose 14. Finally, the clear water is sprayed out through the atomizing nozzle 13 and sprayed onto the TOM diaphragm to simulate the humidity change in the natural environment. When changing the humidity, the solenoid valve 16 needs to be closed to avoid mixing of brine and clear water. The partition 6 divides the interior of the cylinder 5 into two cavities. The partition 8 divides the interior of the rotating cylinder 7 into two cavities, enabling testing of two regions of the TOM diaphragm. The ultraviolet lamp 10 can irradiate the TOM diaphragm to simulate the light in the natural environment. The two-way temperature controller 11 can control the temperature inside the cylinder 5 and the rotating cylinder 7 to simulate the temperature change in the natural environment. Multiple climate tests can be carried out with one device, eliminating the need to frequently transfer the TOM diaphragm, reducing the workload of the staff, and avoiding external interference to the TOM diaphragm, ensuring the accuracy of the test results. The output shaft of the stepping motor 9 can drive the rotating cylinder 7 to rotate 180 degrees, thereby driving the ultraviolet lamp 10, the two-way temperature controller 11, and the atomizing nozzle 13 to rotate 180 degrees to switch the positions of the ultraviolet lamp 10, the two-way temperature controller 11, and the atomizing nozzle 13 for multiple climate tests on the same region of the TOM diaphragm, maximizing the simulation of natural environment changes to comprehensively evaluate the performance of the TOM diaphragm under different climate conditions and improving the accuracy of the test results. After the test is completed, the electric guide rail 3 is controlled to drive the connecting frame 4 to move upward. The connecting frame 4 drives the cylinder 5 to move upward, separating the cylinder 5 from the TOM diaphragm. Then, the first electric conveying roller 21 is started. The first electric conveying roller 21 drives the first driven conveying roller 22 to rotate through gears. Through the transmission of the gears,It is capable of making the first electric conveying roller 21 and the first driven conveying roller 22 rotate towards each other. The first electric conveying roller 21 and the first driven conveying roller 22 convey the tested TOM diaphragm to the left. The tested TOM diaphragm passes through the discharge port 31 and extends between the second electric conveying roller 29 and the second driven conveying roller 30. Start the second electric conveying roller 29. The second electric conveying roller 29 drives the second driven conveying roller 30 to rotate through gears. Through the transmission of the gears, it is capable of making the second electric conveying roller 29 and the second driven conveying roller 30 rotate towards each other. The second electric conveying roller 29 and the second driven conveying roller 30 convey the tested TOM diaphragm to the left, sending the tested TOM diaphragm out of the box body 1. The tested TOM diaphragm will fall onto the receiving plate 32. Connect the vision camera 34 to an external display device. The vision camera 34 can capture the tested TOM diaphragm and display the picture on the external display device to judge the performance of the tested TOM diaphragm. The vision camera 34 can capture the tested area and the untested area of the TOM diaphragm, facilitating the comparison and observation by the staff.

[0037] Refer to Figure 11 It further includes a first supporting strip 35, a second supporting strip 36 and a supporting plate 37. The middle part on the left side of the box body 1 is connected with the first supporting strip 35. Both the left and right sides in the middle part of the box body 1 are connected with the second supporting strip 36. The middle part on the right side of the box body 1 is connected with the supporting plate 37 by bolts.

[0038] Place the TOM diaphragm on the supporting plate 37. The supporting plate 37 holds the TOM diaphragm, and then push the TOM diaphragm. The TOM diaphragm extends between the first electric conveying roller 21 and the first driven conveying roller 22 through the feeding port 23. The second supporting strip 36 on the right side can hold the TOM diaphragm to prevent the TOM diaphragm from sagging and ensure that the TOM diaphragm can smoothly extend between the first electric conveying roller 21 and the first driven conveying roller 22. The first supporting strip 35 and the second supporting strip 36 on the left side can hold the TOM diaphragm to prevent the TOM diaphragm from sagging and ensure that the TOM diaphragm can smoothly extend between the second electric conveying roller 29 and the second driven conveying roller 30.

[0039] Refer to Figure 12 It further includes a pressing plate 38. Both the left and right sides of the cylinder 5 are connected with the pressing plate 38. When the cylinder 5 moves downward, it will drive the pressing plate 38 to move downward. The pressing plate 38 can press the TOM diaphragm to prevent the position of the TOM diaphragm from shifting.
