Description

Technical Field

[0001] The invention belongs to the technical field of ultraviolet weathering testers, and in particular relates to an ultraviolet accelerated weathering tester. Background Art

[0002] UV accelerated weathering tester is used to test the durability of materials under UV radiation to simulate long-term exposure to sunlight. This tester is often used to evaluate the aging resistance of materials (such as plastics, coatings, rubber, etc.).

[0003] When conducting an accelerated UV weathering test on the rearview mirror housing of a car, the side of the rearview mirror housing with the lens is usually placed on a shelf inside the test machine with the lens facing downward, and then an ultraviolet emitter is used to irradiate ultraviolet rays on the upper surface of the rearview mirror housing, so as to test the durability of the rearview mirror housing under ultraviolet irradiation. However, the outer surface of the rearview mirror housing is relatively curved, and the ultraviolet emitter in the prior art is generally installed on the top inner wall of the test machine. When irradiating the rearview mirror housing, the ultraviolet angles received by the rearview mirror housing are inconsistent, which will cause uneven irradiation intensity and distribution of ultraviolet rays, affecting the representativeness and accuracy of the test results. In addition, when the rearview mirror housing is used in daily life, the recessed part of the rearview mirror housing with the lens installed will also be irradiated by ultraviolet rays. When the prior art places the side of the rearview mirror housing with the lens facing downward on the shelf inside the test machine, the recessed part of the rearview mirror housing cannot be irradiated by ultraviolet rays, resulting in the inability to test the durability of the recessed part of the rearview mirror housing, which greatly reduces the accuracy and reliability of the test machine when detecting the rearview mirror housing.

[0041] The operating principle of the present invention is now described as follows:

[0042] In the present invention, when it is necessary to test the durability of the automobile rearview mirror housing under ultraviolet irradiation, the staff puts the end of the rearview mirror housing from the inside of the test frame 2 into the connection box 6, and makes the recessed part of the rearview mirror housing parallel to the side wall of the test frame 2, and makes the rearview mirror housing face upward as a whole, and then makes the end of the rearview mirror housing be located between the two seventh electric telescopic rods 161, and then controls the eighth electric telescopic rod 165 to start, so that the two connecting blocks 164 move outward, so that the two ends of the telescopic plate 162 extend outward, and drives the card plate 163 to move, so that the distance between the two card plates 163 can match the length of the end of the rearview mirror housing, and then controls the seventh electric telescopic rod 161 to start, driving the telescopic plate 162 and the card plate 163 The first electric slide rail 141 is controlled to start, and the first slide plate 142 is driven to move, so that the first slide plate 142 and the middle part of the rearview mirror housing are in the same plane. The first electric telescopic rod 143 is controlled to start, and the first side plate 144 is driven to move, so that the first side plate 144 corresponds to the middle part of the rearview mirror housing. The second electric telescopic rod 145 is controlled to start, and the mounting plate 146 is driven to move toward the recessed part of the rearview mirror housing. When the first ultraviolet emitter 1413 arranged above the mounting plate 146 enters the recessed part of the rearview mirror housing, the second electric telescopic rod 145 is controlled to stop extending, and the first ultraviolet emitter 1413 is controlled to start. The ultraviolet light emitter 1413 is started to irradiate the inner wall of the recessed part of the rearview mirror housing. At this time, the heater 7, the refrigerator 8 and the humidity controller 9 are controlled to control the temperature and humidity in the test frame 2 to ensure that when the ultraviolet durability test is performed on the rearview mirror housing, the internal environment of the test machine is the same as the specific use environment. In this process, the second ultraviolet light emitter 1417 is controlled to start to emit ultraviolet light to the rearview lens in the recessed part of the rearview mirror housing. At this time, the ultraviolet light will be refracted to the inner wall of the recessed part of the rearview mirror housing. After a period of time, the second motor 1418 is controlled to start to drive the side rod 1416 to rotate, and the angle of the ultraviolet light irradiated on the rearview lens by the second ultraviolet light emitter 1417 is adjusted to simulate the ultraviolet light passing through at different angles during specific use. After the rearview lens is irradiated on the inner wall of the recess of the rearview mirror housing, after completing the ultraviolet durability test on the recess of the rearview mirror housing, the third electric telescopic rod 148 is controlled to start, driving the moving plate 149 to move, so that the fourth electric telescopic rod 1410 moves to the inside of the recess of the rearview mirror housing, and then the fourth electric telescopic rod 1410 is controlled to start, and the inner wall of the recess of the rearview mirror housing is supported by the first clamping plate 1411, so as to fix the rearview mirror housing, and then the seventh electric telescopic rod 161 is controlled to shrink a distance, and then the second electric slide rail 151 is controlled to start, driving the second slide plate 152 to move, so that the second slide plate 152 and the middle part of the rearview mirror housing are in the same plane, and then the fifth electric telescopic rod 153 is controlled to start,The second side plate 154 is driven to move so that the second side plate 154 corresponds to the middle part of the rearview mirror housing, and then the third motor 1512 is controlled to start, and the corresponding mounting rod 157 is driven to rotate so that the angle of the two auxiliary plates 158 is substantially the same as the bending angle of the outer surface of the rearview mirror housing. Then the sixth electric telescopic rod 155 is controlled to start, and the mounting block 156 and the auxiliary plate 158 are driven to approach the outer surface of the rearview mirror housing. Then the third ultraviolet emitter 1510, the fourth ultraviolet emitter 17 and the fifth ultraviolet emitter 167 are controlled to start, and the outer surface and the end of the rearview mirror housing are irradiated. At the same time, the temperature and humidity in the test frame 2 are controlled by controlling the heater 7, the refrigerator 8 and the humidity controller 9 to ensure that when the rearview mirror housing is subjected to the ultraviolet durability test, the internal environment of the test machine is the same as the specific use environment. Since the angle between the mounting block 156 and the auxiliary plate 158 is substantially the same as the bending angle of the outer surface of the rearview mirror housing, when the ultraviolet rays emitted by the third ultraviolet emitter 1510 irradiate the outer surface of the rearview mirror housing, the ultraviolet rays emitted by the third ultraviolet emitter 1510 irradiate the outer surface of the rearview mirror housing. The irradiation angle is the same to prevent uneven irradiation intensity and distribution of ultraviolet rays. After ultraviolet rays are detected on the outer surface of the rearview mirror housing, the durability of the rearview mirror housing under ultraviolet rays can be judged by observing the changes in the outer surface of the rearview mirror housing. The irradiation angle of the third ultraviolet emitter 1510 can be adjusted according to the bending angle of the outer surface of the rearview mirror housing to ensure that the ultraviolet rays emitted by the third ultraviolet emitter 1510 are irradiated on the outer surface of the rearview mirror housing at the same irradiation angle to prevent uneven irradiation intensity and distribution of ultraviolet rays, which affects the representativeness and accuracy of the test results. At the same time, ultraviolet rays can be irradiated on the inner wall of the recessed part of the rearview mirror housing to perform durability tests on the inner wall of the recessed part of the rearview mirror housing, thereby improving the accuracy of durability testing of the rearview mirror housing under ultraviolet rays. In addition, the situation that ultraviolet rays are irradiated on the inner wall of the recessed part of the rearview mirror housing through the rearview lens at different angles during specific use can be simulated, so as to more accurately test the durability of the rearview mirror housing in a real environment, thereby improving the test effect and reliability of the device when performing ultraviolet accelerated weathering tests on the rearview mirror housing.
