[0037] To accelerate the simulation of the aging situation of the sample to be tested caused by light during use, an embodiment of the present invention provides an accelerated aging device. Figure 1 It is a structural block diagram of an accelerated aging device provided by an embodiment of the present invention. Figure 2 It is a structural schematic diagram of an accelerated aging device provided by an embodiment of the present invention. Refer to Figure 1 and Figure 2 , the accelerated aging device includes a light condensing module 100, an angle adjustment module 200, and a carrying structure 300; the light condensing module 100 is used to modulate the aging light beam emitted by the aging light source 400 to the light-receiving surface of the sample to be tested 500, and the aging light beam includes a solar beam; the carrying structure 300 is used to fixedly carry the light condensing structure 100 and the sample to be tested 500; the angle adjustment module 200 is connected to the carrying structure 300 and is used to synchronously adjust the postures of the light condensing module 100 and the carrying structure 300 according to the position information of the aging light source 400 so that the incident angle of the aging light beam on the light condensing module 100 is within a preset angle range.

[0038] Refer to Figure 1 and Figure 2, the aging light source 400 emits an aging light beam. When the aging light beam irradiates on the surface of the sample 500 to be tested, the sample 500 to be tested can be aged. The higher the intensity of the aging light beam, the faster the aging speed of the sample 500 to be tested. The aging light beam can include the sun and / or artificial light sources, and the aging light beam can include sunlight and / or artificial light. Using the sun as the aging light source can save energy and reproduce the aging process of the sample 500 to be tested under natural conditions. The sample 500 to be tested is fixed on the carrying structure 100. The condensing module 100 can reflect or refract the aging light beam to the light-receiving surface of the sample 500 to be tested, so as to increase the intensity of the aging light beam received by the light-receiving surface, thereby accelerating the aging process of the sample 500 to be tested. The sunlight modulated by the condensing module 100 can be evenly irradiated on the light-receiving surface of the sample 500 to be tested. The angle adjustment module 200 can detect the intensity distribution of the aging light beam, thereby determining the position of the aging light source, and synchronously adjusting the poses of the condensing module 100 and the carrying structure 300 according to the position of the aging light source, so that the condensing module 100 can reflect or refract as much aging light beam as possible to the light-receiving surface of the sample 500 to be tested, thereby increasing the intensity of the aging light beam received by the light-receiving surface and accelerating the aging process of the sample 500 to be tested. The preset angle range is the angle used to detect whether the condensing module 100 and the carrying structure 300 are directly facing the aging light source. When the incident angle of the aging light beam on the condensing module 100 is within the preset angle range, most or even all of the aging light beam modulated by the condensing module 100 can be received by the light-receiving surface. At this time, the condensing module 100 and the carrying structure 300 are directly facing the aging light source. It should be noted that before the accelerated aging simulation starts, the relative positions of the condensing module 100 and the carrying structure 300 are fixed as follows: when the incident angle of the aging light beam on the condensing module 100 is within the preset angle range, the aging light beam is vertically incident on the light-receiving surface of the sample 500 to be tested, and the intensity of the aging light beam received by the light-receiving surface is the highest. When the angle adjustment module 200 adjusts the poses of the condensing module 100 and the carrying structure 300, the relative positions of the condensing module 100 and the carrying structure 300 remain unchanged.

[0039] The accelerated aging device provided by the embodiment of the present invention modulates the aging light beam to the light-receiving surface of the sample to be tested through the condensing module, accelerates the aging process of the sample to be tested, and realizes simulating the aging situation of the sample to be tested after a long time in a short time. In addition, the angle adjustment module synchronously adjusts the poses of the condensing module and the carrying structure, so that the relative positions of the condensing module and the carrying structure will not change, making the adjustment logic of the angle adjustment module simpler, and at the same time ensuring that the condensing module modulates as much aging light beam as possible to the light-receiving surface.

[0040] Figure 3 is the structural block diagram of the angle adjustment module provided by the embodiment of the present invention. Refer to Figure 1 , Figure 2 and Figure 3, the angle adjustment module 200 includes an optical detection unit 201, a control unit 202, and a rotation unit 203; the optical detection unit 201 is configured to detect the position information of the aging light source 400; the control unit 202 is communicatively connected to the optical detection unit 201 and the rotation unit 202 respectively, and is configured to receive the position information of the aging light source 400, determine the rotation information of the condenser module 100 and the carrying structure 300 based on the position information of the aging light source 400, and send the rotation information to the rotation unit 203; the rotation unit 203 is connected to the condenser module 100 and is configured to synchronously adjust the poses of the condenser module 100 and the carrying structure 300 according to the rotation information.

[0041] Reference Figure 1 and Figure 2 , the optical detection unit 201 can determine the azimuth where the intensity of the aging light beam is the largest and can be received according to the intensity distribution of the aging light beam, that is, the position information of the aging light source 400. The control unit 202 determines the angles that the condenser module 100 and the carrying structure 300 need to rotate to turn to the azimuth where the aging light source 400 is located according to the position information of the aging light source 400, and sends the rotation information to the rotation unit 203. The rotation unit 203 rotates the condenser module 100 and the carrying structure 300 by corresponding angles so that the incident angle of the aging light beam on the condenser module 100 is within a preset angle range. When the rotation unit 203 adjusts the poses of the condenser module 100 and the carrying structure 300, the relative positions of the condenser module 100 and the carrying structure 300 remain unchanged.

[0042] Figure 4 is a schematic structural diagram of an accelerated aging device that is aligning the position of the aging light source provided by an embodiment of the present invention, Figure 5 is a top view of an accelerated aging device provided by an embodiment of the present invention. Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the rotation unit 203 includes a first motor 2031, a second motor 2032, and a rotation support platform 2033; the carrying structure 300 is disposed on one side of the rotation support platform 2033, and the carrying structure 300 includes a first carrying plate 301 and a second carrying plate 302. One end of the first carrying plate 301 and the second carrying plate 302 are rotatably connected; the first motor 2031 is configured to adjust the included angle between the first carrying plate 301 and the second carrying plate 302 according to the rotation information; the second motor 2032 is configured to drive the rotation support platform 2033 to drive the carrying structure 300 to rotate according to the rotation information; the first motor 2031 is configured to receive a height rotation signal and adjust the orientation of the condenser module 100 along the first direction X, and the second motor 2032 is configured to receive an azimuth rotation signal and adjust the orientation of the condenser module 100 along the second direction Y, and the first direction X and the second direction Y are different.

[0043] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ,The position information of the aging light source 400 includes azimuth information and height information. The height information includes the angle formed by the connection line between the aging light source 400 and the geometric center of the light-receiving surface and the third direction Y1, and the azimuth information is the position where the projection of the aging light source 400 on the plane where the light-receiving surface is located. The rotation information includes a height rotation signal and an azimuth rotation signal. The control unit 202 determines the height rotation signal according to the height information and determines the azimuth rotation signal according to the azimuth information. Specifically, according to the height information of the aging light source 400, the control unit 202 can determine the angle by which the first carrier plate 301 needs to be tilted. The first motor 2031 can rotate the first carrier plate 301 with the connection point between the first carrier plate 301 and the second carrier plate 302 as the base point, so as to adjust the inclination angle of the condensing module 100 and the bearing structure 300 relative to the second carrier plate 302, and the inclination angle is also equal to the angle formed by the first carrier plate 301 and the second carrier plate 302. When the inclination angle is equal to or approximately equal to the angle formed by the connection line between the aging light source 400 and the geometric center of the light-receiving surface and the third direction Y1, the second motor 2032 rotates the rotating support platform 2033 according to the received azimuth rotation signal, so as to drive the condensing module 100 and the bearing structure 300 to rotate along the second direction Y. Since there is a certain angle between the first carrier plate 301 and the second carrier plate 302, the rotating support platform 2033 can change the orientation of the condensing module 100, so that the tilting direction of the condensing module 100 corresponds to the position of the aging light source 400, and the incident angle of the aging light beam on the condensing module 100 is within the preset angle range. It can be understood that the control unit 202 can send the height rotation signal and the azimuth rotation signal at the same time, and the first motor 2031 and the second motor 2032 can work at the same time.

[0044] Optionally, the bearing structure includes a fixing unit for fixing the sample to be tested. The fixing unit can ensure that the sample to be tested does not move when the bearing structure is tilted, improving the stability of the sample to be tested during the accelerated aging process.

[0045] Reference Figure 1 and Figure 4 ,The angle adjustment module 200 further includes a telescopic unit 204; the first motor 2031 is connected to the telescopic unit 204, and the first motor 2031 is used to control the telescopic unit 204 to expand and contract according to the rotation information to adjust the included angle between the first carrier plate 301 and the second carrier plate 302.

[0046] The first motor 2031 can control the extension and retraction of the telescopic unit 204. When the telescopic unit 204 extends, the angle between the first bearing plate 301 and the second bearing plate 302 increases, and the inclination angles of the light condensing module 100 and the bearing structure 300 increase. When the telescopic unit 204 retracts, the angle between the first bearing plate 301 and the second bearing plate 302 decreases, and the inclination angles of the light condensing module 100 and the bearing structure 300 decrease. Thus, the first motor 2031 can adjust the angle between the first bearing plate 301 and the second bearing plate 302 according to the rotation information by controlling the telescopic movement of the telescopic unit 204, so that the incident angle of the aging beam on the light condensing module 100 is within a preset angle range. Optionally, the telescopic unit 204 includes, but is not limited to, a hydraulic rod.

[0047] Reference Figure 1 , Figure 2 and Figure 4 , the light condensing module 100 includes at least one plane mirror 101, and the plane mirror 101 is used to reflect the aging beam to the light receiving surface. The reflectivity of the plane mirror is 95%, and almost all the aging beams can be reflected to the light receiving surface of the sample 500 to be measured, and the spatial distribution of the aging beam reflected by the plane mirror 101 will not change. When the aging beam is sunlight, the aging beam is evenly distributed on the light receiving surface of the sample 500 to be measured, and the light receiving surface of the sample 500 to be measured can be aged synchronously.

[0048] Figure 6 is a schematic diagram of a plane mirror and a sample to be measured provided by an embodiment of the present invention. Reference Figure 6 , the angle between the plane mirror 101 and the light receiving surface of the sample 500 to be measured is α, the distance between the edge of the plane mirror 101 close to the sample 500 to be measured and the light receiving surface in the third direction Y1 is b, the distance between the edge of the plane mirror 101 far from the sample 500 to be measured and the light receiving surface in the third direction Y1 is c, the minimum distance between the edge of the plane mirror 101 close to the sample 500 to be measured and the light receiving surface in the fourth direction X1 is d1, and the minimum distance between the edge of the plane mirror 101 far from the sample 500 to be measured and the light receiving surface in the fourth direction X1 is d2; the third direction Y1 intersects with the light receiving surface, and the fourth direction X1 intersects with the third direction Y1; wherein, and / or,

[0049] Reference Figure 6, when the third light beam S3 is incident from the edge on the side of the mirror 101 close to the sample 500 to be measured, the reflected light is the first light beam S1; when the third light beam S3 is incident from the edge on the side of the mirror 101 far from the sample 500 to be measured, the reflected light is the second light beam S2. When the third light beam S3 is incident on the plane mirror 101 at an angle perpendicular to the light-receiving surface of the sample 500 to be measured, the incident angle of the third light beam S3 is α, and the angles between the first light beam S1 and the second light beam S2 and the fourth direction are 2α - 90. When the first light beam S1 emerging from the edge on the side of the plane mirror 101 close to the sample 500 to be measured just enters the edge on the side of the light-receiving surface of the sample 500 to be measured close to the plane mirror 101, the tangent value of the angle formed by the first light beam S1 and the fourth aspect X1 is Therefore, when , the first light beam S1 just enters the edge on the side of the light-receiving surface of the sample 500 to be measured close to the plane mirror 101. When the plane mirror 101 moves to make the value of increases, the first light beam S1 can still enter the sample 500 to be measured. Therefore, to make the first light beam S1 enter the sample 500 to be measured, it is necessary to satisfy Similarly, when the second light beam S2 emerging from the edge on the side of the plane mirror 101 far from the sample 500 to be measured just enters the edge on the side of the light-receiving surface of the sample 500 to be measured far from the plane mirror 101, the tangent value of the angle formed by the second light beam S2 and the fourth aspect X1 is When , the second light beam S2 just enters the edge on the side of the light-receiving surface of the sample 500 to be measured far from the plane mirror 101. When the plane mirror 101 moves to make the value of decreases, the second light beam S2 can still enter the sample 500 to be measured. Therefore, to make the second light beam S2 enter the sample 500 to be measured, it is necessary to satisfy Therefore, when and , all the aging light beams reflected by the plane mirror 101 enter the light-receiving surface of the sample 500 to be measured. At this time, the utilization rate of the aging light beam is the highest.

[0050] When all the aging light beams reflected by the plane mirror 101 enter the light-receiving surface of the sample 500 to be measured, the ratio β of the intensity of the aging light beam received by the light-receiving surface of the sample 500 to be measured to the intensity of the aging light beam received by the light-receiving surface without using the accelerated aging device is:

[0051]

[0052] Among them, S0 is the area of the reflecting surface of the plane mirror 101, and S1 is the area of the light spot of the reflected aging light beam on the light-receiving surface. According to the reflection theorem, it can be obtained that:

[0053]

[0054] β can be simplified to:

[0055] β = 1 + 4sin(2α - 90).

[0056] Optionally, the intensity of the aging beam incident on the plane mirror is I0, and the intensity of the aging beam reflected by the plane mirror to the light-receiving surface is I1; where the reflectivity of the plane mirror is usually above 95%. If it is ensured that all the aging beams reflected by the plane mirror are incident on the light-receiving surface of the sample to be tested 500, then it can be ensured that at this time, the utilization rate of the aging beam is the highest, avoiding energy waste.

[0057] Reference Figure 1 and Figure 5 , the condensing module 100 includes at least two plane mirrors 101, and there are at least two plane mirrors 101 that are centrosymmetric with the geometric center of the light-receiving surface as the base point. Figure 5 The accelerated aging device in includes four plane mirrors 101, and the plane mirrors 101 are centrosymmetric with the geometric center of the light-receiving surface of the sample to be tested 500 as the base point, so that the aging beams located around the sample to be tested 500 can be reflected onto the light-receiving surface of the sample to be tested 500, improving the utilization rate of the aging beam. In addition, the plane mirror 101 can be increased according to requirements, and the plane mirrors 101 can be arranged in a direction parallel to or perpendicular to the plane where the light-receiving surface is located.

[0058] Reference Figure 1 , Figure 3 and Figure 4 , the condensing module 100 further includes a support rod 600, and the support rod 600 is used to support the plane mirror 101; the height of the support rod 600 is adjustable. The plane mirror 101 is fixed on the support rod 600, and the support rod 600 includes a telescopic structure, and the length of the support rod 600 can be adjusted by adjusting the telescopic structure, thereby changing the position of the plane mirror 101. In addition, the angle of the plane mirror 101 fixed on the support rod 600 is also adjustable. By adjusting the length of the support rod 600 and the angle of the plane mirror 101, more aging beams can be incident on the light-receiving surface.

[0059] The accelerated aging method based on the above accelerated aging device includes: first, fixing the sample to be tested on the bearing structure, adjusting the relative height between the condensing module and the bearing structure, and ensuring that all the aging beams are irradiated on the sample to be tested. Finally, turning on the angle adjustment module, placing the accelerated aging device stably in the test environment to start the aging test.
