Detailed Description
Embodiments of the present invention are described in further detail below with reference to the accompanying drawings and examples. The following examples are illustrative of the invention but are not intended to limit the scope of the invention.
As shown in fig. 1 to 6, an embodiment of the present invention provides an aging test apparatus, which includes a light source 100, a first object 102, a second object 106, and a light adjuster 110; a first sample region 104 is formed on the first object 102; the second object 106 is formed with a second sample area 108, along the light emitting path of the light source 100, the first object 102 and the second object 106 are sequentially arranged, in a plane perpendicular to the light emitting path of the light source 100, the projection of the first object 102 is smaller than the projection of the second object 106, and the second sample area 108 is formed at a portion of the second object 106 beyond the first object 102; the light adjusting member 110 is disposed in the light emitting path of the light source 100 and located between the light source 100 and the first object 102; the light source 100 is adapted to apply illumination to one of the first sample region 104 and the second sample region 108 via the light modulating member 110, and the light source 100 is further adapted to apply illumination directly to the other of the first sample region 104 and the second sample region 108.
According to the burn-in apparatus provided by the embodiment of the first aspect of the present invention, by providing the first object 102 and the second object 106, and providing the first sample area 104 and the second sample area 108 on the first object 102 and the second object 106, respectively, the samples can be placed on the first sample area 104 and the second sample area 108, respectively. By providing the first and second articles 102, 106 in different sizes, the first and second sample areas 104, 108 on the first and second articles 102, 106 are each capable of receiving light. The light intensity applied to one of the first sample area 104 and the second sample area 108 can be changed by arranging the light adjusting member 110 on the light emitting path of the light source 100 and by matching the light adjusting member 110 with the light source 100, and the other of the first sample area 104 and the second sample area 108 is directly applied with light by the light source 100, so that different environmental factors can be simulated simultaneously in the first sample area 104 and the second sample area 108 in a single aging test process. When the types of the samples are the same, the aging test of the same sample under different environmental factors can be completed in a single test process, and the aging test efficiency of the same sample is improved. When the types of the samples are different, the aging test of different samples under different environmental factors can be completed simultaneously in a single test process, and the universality of the aging test device is improved. More importantly, through the adjustment of the light adjusting piece 110, the illumination intensity applied to the first sample area 104 or the second sample area 108 can be changed, so that more light intensity environments can be simulated, and the application scene of the aging test device is enriched.
Referring to fig. 1 to 6, in the embodiment of the invention, the aging test apparatus includes a box 112, and by setting the box 112 and setting the components such as the light source 100, the first object 102, the second object 106, and the light adjusting member 110 in the box 112, the influence of external factors on the aging test result can be avoided. It is understood that the storage space is formed inside the case 112, and the light source 100, the first storage object 102, the second storage object 106 and the light adjusting element 110 can be disposed in the storage space.
Referring to fig. 1, in the embodiment of the present invention, a door 136 is hinged to the case 112, and the opening or closing of the storage space can be achieved by opening or closing the door 136. After the door 136 is opened, the tester can place the above components in the storage space, and after the door 136 is closed, the storage space can be closed for aging test.
In other embodiments, the case 112 may be provided with a vent 138 to dissipate heat in the object space, reduce thermal aging interference, and improve accuracy of the aging test result.
In other embodiments, an observation window may be provided on the box 112, so that the tester can observe the progress of the aging test in the storage space in real time.
The light source 100 may be mounted to a top wall within the storage space, i.e., as shown in fig. 1, the light source 100 may be mounted above within the storage space. In the embodiment of the present invention, the light source 100 may include a single light source 100 structure such as an ultraviolet lamp, a high-pressure mercury lamp, or a combined light source 100 structure including a plurality of LED beads. Accordingly, in the embodiment of the present invention, parameters such as the power of the light source 100, the illumination intensity of the light source 100, and the light emitting type may be adjusted.
A light adjusting member 110 is disposed below the light source 100, and it is understood that the light adjusting member 110 is disposed on the light emitting path of the light source 100. The material of the light adjusting member 110 can be made of ultraviolet quartz glass, a mirror surface of the light adjusting member 110 can be coated with a film, and under the condition of coating, the light transmittance of the light adjusting member can reach 99%, and the light condensing strength is high.
In other embodiments, the light adjuster 110 may be made of quartz material to form other components capable of focusing light. That is, by providing the dimming member 110, the focal length of the light source 100 can be changed, and accordingly, the corresponding illumination intensity can be changed when the light source 100 is dimmed by the dimming member 110.
Referring to fig. 1, in the embodiment of the present invention, a first object 102 and a second object 106 are disposed in the object placing space, wherein, along the direction from top to bottom as shown in fig. 1, the first object 102 is disposed above, and the second object 106 is disposed below the first object 102. Meanwhile, in the top-down direction as shown in fig. 1, the first placement object 102 has a relatively small size, and the second placement object 106 has a relatively large size. A first sample region 104 is formed on the first object 102, the first sample region 104 being for holding a sample, and a second sample region 108 is formed on the second object 106, the second sample region 108 being for holding a sample as well. Wherein the second sample region 108 is formed at a portion of the second placement member 106 beyond the first placement member 102. The purpose of this arrangement is to avoid the first object 102 from blocking the second sample area 108 on the second object 106, so that the second sample area 108 can receive light normally.
In embodiments of the present invention, the first sample region 104 and the second sample region 108 may be used to house an asphalt sample or other sample that is to be tested for aging tests.
In addition, as shown in fig. 2, a plurality of first sample areas 104 may be provided, and a plurality of first sample areas 104 may be provided at intervals along the circumferential direction of the first object 102; likewise, a plurality of second sample regions 108 may be provided, with the plurality of second sample regions 108 being spaced apart along the circumference of the second article 106. In a specific arrangement, it is sufficient to avoid the first object 102 having a shielding relationship with the second sample area 108, in other words, the number of the first sample area 104 and the second sample area 108 is not specifically limited.
It should be noted that, in the embodiment of the present invention, the samples in the first sample area 104 and the second sample area 108 may be the same type of sample or different types of samples. When the samples on the first sample region 104 and the second sample region 108 are the same type of sample, the burn-in test detection of the same type of sample at different illumination intensities can be achieved by applying different illumination intensities at the first sample region 104 and the second sample region 108. When the samples on the first sample region 104 and the second sample region 108 are different types of samples, the burn-in test detection of the different types of samples at the different illumination intensities can be achieved by applying different illumination intensities at the first sample region 104 and the second sample region 108.
In the embodiment of the present invention, the height of the light source 100 and the height of the light modulating member 110 may be set in an adjustable manner.
Specifically, when the height of the light source 100 is adjustable, the adjustment of the intensity of illumination applied to the light source 100 may be achieved by the adjustment of the height of the light source 100. That is, when the light source 100 is closer to the first object 102 and the second object 106, the light intensity of the light source 100 applied to the first object 102 and the second object 106 is larger, and when the light source 100 is farther from the first object 102 and the second object 106, the light intensity of the light source 100 applied to the first object 102 and the second object 106 is smaller.
When the height of the light modulation element 110 is adjustable, the adjustment of the illumination intensity applied to the first and second placement objects 102 and 106 can be achieved by adjusting the height of the light modulation element 110. That is, when the focal point of the light source 100 adjusted by the light adjusting member 110 is focused on the first object 102, the light intensity of the light source 100 applied to the first object 102 by the light adjusting member 110 is greater than the light intensity of the light source 100 directly applied to the second object 106. When the focal point of the light source 100 adjusted by the light adjusting member 110 is focused on the second object 106, the light intensity of the light source 100 applied to the second object 106 by the light adjusting member 110 is greater than the light intensity of the light source 100 directly applied to the first object 102.
It should be noted that, in the embodiment of the present invention, in order to achieve the effect of different illumination intensities applied to the first object 102 and the second object 106, so as to simulate different environmental factors during the aging test, the light adjusting member 110 is only used to adjust the illumination intensity applied to the first object 102 or the second object 106. That is, when the light modulator 110 focuses the light source 100 on the first object 102, the second object 106 only receives the direct illumination of the light source 100; when the light modulator 110 focuses the light source 100 on the second object 106, the first object 102 only receives the direct illumination of the light source 100.
In other embodiments, the light source 100 and the light modulation member 110 may be set to be in a height-adjustable form at the same time, and by adopting such a setting manner, more environmental factors may be simulated, so as to enrich the application range of the aging test apparatus.
In other embodiments, the light adjuster 110 may not be disposed in the light-emitting path of the light source 100, so that the test of applying different illumination intensities to the first sample region 104 and the second sample region 108 may be implemented only by adjusting the height of the light source 100. This is because the first object 102 and the second object 106 are formed with a certain offset in the height direction, that is, the distances between the first object 102 and the second object 106 and the light source 100 are not equal, compared to the distance between the first object 102 and the light source 100 is closer, so that the light intensity applied to the first object 102 by the light source 100 is greater than the light intensity applied to the second object 106.
According to one embodiment of the invention, the height adjustment assembly includes a base 116, a post 118, and a telescoping member 122; wherein, the upright post 118 is connected to the base 116, and an illumination intensity scale line 120 is formed on the upright post 118; the telescoping member 122 is movably coupled to the post 118, and the dimmer member 110 is coupled to an end of the telescoping member 122 facing away from the post 118.
Referring to fig. 3, in the embodiment of the present invention, the height of the light adjusting member 110 is adjustable, specifically, the base 116 is disposed at the bottom wall of the storage space, the stand column 118 is connected to the base 116, the telescopic member 122 is movably connected to the stand column 118, and the telescopic member 122 may be a telescopic rod, and an end of the telescopic rod facing away from the stand column 118 is used for mounting the light adjusting member 110. It should be noted that, the light adjusting member 110 may be fixedly connected to an end of the telescopic member 122 facing away from the upright post 118, and the light adjusting member 110 may also be rotatably connected to an end of the telescopic member 122 facing away from the upright post 118. When the light adjusting member 110 is rotatably connected to one end of the telescopic member 122 away from the upright post 118, the light adjusting angle of the light adjusting member 110 can be adjusted, so that the light path of the light source 100 can be adjusted from different angles, and the illumination of different angles can be realized for the first sample area 104 or the second sample area 108.
It should be noted that, after the position of the light adjusting member 110 is adjusted, the light adjusting member 110 may be self-locked with respect to the upright post 118 by a self-locking member. The self-locking member may be a self-locking member commonly known in the related art, and will not be described herein.
As shown in fig. 3, in an embodiment of the present invention, illumination intensity graduation marks 120 are formed on the upright post 118. By providing the illumination intensity graduation marks 120 on the upright post 118, convenient adjustment of the dimming element 110 can be achieved. For example, taking the light adjusting member 110 to adjust the illumination intensity on the first sample area 104 as an example, after the position of the light source 100 is fixed, the illumination intensity applied on the first sample area 104 can be adjusted by adjusting the position of the light adjusting member 110 relative to the first sample area 104. For example, when the light modulation member 110 is 5 cm from the first sample region 104, the intensity of illumination applied to the first sample region 104 is 20 lux, and accordingly, it may be recorded that the intensity of illumination at this position of the light modulation member 110 on the pillar 118 is 20 lux; when the light modulation member 110 is 10 cm from the first sample region 104, the intensity of illumination applied to the first sample region 104 is 10 lux, and accordingly, the intensity of illumination corresponding to the position of the light modulation member 110 on the pillar 118 may be recorded as 10 lux. Through such setting, can make things convenient for the experimenter to adjust luminance piece 110, and then need not to measure again and apply the illumination intensity on first sample district 104 and can directly confirm the illumination intensity value that adjusts luminance piece 110 and correspond in this mounted position department on stand 118.

For example, when the light modulation member 110 is spaced 5 cm from the first sample region 104, the illumination intensity applied to the first sample region 104 is 20 lux, and accordingly, the diameter of the illumination range graduation mark 124 formed on the first sample region 104 is 5 cm; when the light modulation member 110 is spaced 10 cm from the first sample region 104, the intensity of light applied to the first sample region 104 is 10 lux, and accordingly, the diameter of the light range graduation mark 124 formed on the first sample region 104 is 10 cm. Through such setting, can make things convenient for the experimenter to realize placing the sample. For example, when an illumination intensity of 10 lux needs to be applied to the sample, the sample is only required to be placed within the range defined by the illumination range graduation line 124 corresponding to 10 cm, so that the illumination intensity received by the sample at that position is ensured to be 10 lux.
