DETAILED DESCRIPTION

[0021] The technical schemes in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] To solve the problem that several lamps placed in the existing device for detecting lamp aging are easy to be missed during detection, please refer to Figures 1-4The utility model provides a kind of device for detecting lamp aging, can ensure that detection tool carries out full coverage detection inside device.The device for detecting lamp aging has the aging test chamber 1 with several ultraviolet lamps 2, and several ultraviolet lamps 2 are arranged side by side on the top wall of aging test chamber 1, to make the ultraviolet lamp 2 overall covering irradiation to the several lamps placed in the space inside aging test chamber 1.In addition, the aging test chamber 1 has temperature and humidity adjusting function, to carry out the damp heat aging test of lamp, high temperature aging test.The inside of aging test chamber 1 is slidably inserted with bearing plate 3, mainly for stably placing several lamp structures 4, the inside of aging test chamber 1 is provided with image detection assembly 5 between ultraviolet lamp 2 and lamp structure 4, in actual application, by placing several lamp structures 4 on bearing plate 3 according to certain order, then close aging test chamber 1 and enable several ultraviolet lamps 2, carry out certain period ultraviolet irradiation test, utilize ultraviolet lamp 2 to simulate the influence of solar ultraviolet on lamp structure 4 shell and internal element, and cooperate with image detection assembly 5 electrically connected with aging test chamber 1, after ultraviolet irradiation test ends, detect whether the surface of lamp structure 4 appears fading, cracking and other conditions, to reach the purpose of lamp aging detection.

[0023] Specifically, the aging test box 1 is composed of an inner cavity frame, a rear baffle mounted on the back of the inner cavity frame, and a control frame integrally connected with one side of the inner cavity frame. The rear baffle and the back of the inner cavity frame form a gap cavity. The image detection assembly 5 includes an image detection structure 501 arranged above the lamp structure 4. A slot 502 extending into the control frame and matching the side shape of the image detection structure 501 is formed on one side of the inner cavity frame. A through slot for communicating the gap cavity is formed on the rear wall of the inner cavity frame. A sliding block 503 passing through the through slot is mounted at the rear end of the image detection structure 501. A lead screw structure 504 passing through the sliding block 503 is rotatably connected in the gap cavity. A stepping motor 505 in transmission connection with the lead screw structure 504 is mounted in the control frame and the gap cavity. When the lamp structure 4 is not subjected to surface aging image detection, the image detection structure 501 is embedded in the space of the slot 502. At this time, the top of the image detection structure 501 is not irradiated by the ultraviolet lamp 2 when it is turned on, thereby effectively avoiding the influence on its service life. In addition, in actual application, after the ultraviolet lamp 2 finishes irradiation, the stepping motor 505 is operated intermittently. The lead screw structure 504 is controlled to rotate at a set rate in a set direction by operating the stepping motor 505, so as to drive the sliding block 503 to move the image detection structure 501 along the outer surface of the lead screw structure 504 at a uniform speed to one side intermittently. In the gap where the sliding block 503 stops moving, the image detection structure 501 is turned on. By means of high-definition camera and image processing technology, the appearance change of the lamp structure 4 is captured in real time, and whether there is fading, cracking and other defects is identified, so as to ensure that the appearance quality of the lamp structure 4 meets the standard. By driving the image detection structure 501 to move horizontally at a uniform speed in the space of the inner cavity frame, the detection range of the image detection structure 501 can be effectively expanded, and the top surfaces of the lamp structures 4 below can be detected to avoid omission.

[0024] As described above, the rear wall of the inner cavity frame is provided with a through slot. Therefore, it is easy for sundries to enter the space in the gap cavity along the through slot. Since there is only the through slot in the gap cavity, it is difficult to clean the sundries entering. In order to effectively prevent sundries from entering the gap cavity, as shown in Figure 2 two inclined strips 506 are mounted on the top wall and the bottom wall of the through slot. The height sum of the two inclined strips 506 is greater than the height of the through slot. A gap allowing the sliding block 503 to move horizontally is formed between the two inclined strips 506. The form of the through slot is adjusted by using the two inclined strips 506, so that the original opening in the front-rear direction is adjusted to a downward state without affecting the horizontal movement of the sliding block 503. This can effectively avoid the entry of sundries into the gap cavity along the through slot.

[0025] In a conventional case, the lamp structure 4 is placed in the aging test box 1, usually in a flat or plug-in state, but during the aging test, the lamp structure 4 may be subjected to environmental factors such as temperature changes, humidity changes, etc. If the lamp structure 4 is not fixed, it may be disturbed by these environmental factors, resulting in unstable test results. In order to effectively avoid the influence of external unstable factors on the detection of the lamp structure 4, as shown in Figure 1 、 Figures 3-4 , the top of the bearing plate 3 is provided with a plurality of parallel installation grooves 301 for embedding the lamp structure 4, and a rectangular groove 302 is formed in the bottom wall of each installation groove 301. A limiting component 303 is installed between the bottom of the bearing plate 3 and the plurality of installation grooves 301 for extruding the connecting end of the lamp structure 4 from the side when the lamp structure 4 is embedded in the installation groove 301.

[0026] Specifically, the installation groove 301 is composed of a forward and backward axially arranged push groove 3011, an inner embedding groove 3012 connected to one side of the push groove 3011, a plurality of semicircular grooves 3013 connected to the other side of the push groove 3011, and a positioning groove 3014 arranged at the bottom wall of the semicircular groove 3013 and the push groove 3011. The depth of the inner embedding groove 3012 is less than the depth of the push groove 3011, and the bottom wall of the inner embedding groove 3012 is level with the bottom wall of the push groove 3011 and the semicircular groove 3013. In actual application, the lamp structure 4 is pushed from front to back along the path of the push groove 3011, and at the designated position, the lamp structure 4 is pushed into the semicircular groove 3013 on one side, and the bottom is stably embedded in the bottom wall of the positioning groove 3014, so as to achieve the purpose of temporary positioning. The limiting component 303 includes a push plate 3031 arranged in the plurality of inner embedding grooves 3012, a plurality of arc-shaped plates 3032 installed on one side of the push plate 3031, and the arc-shaped plates 3032 correspond to the semicircular grooves 3013 on one side. An electric push rod 3033 is installed at the bottom of the bearing plate 3, an adapter plate 3034 is installed at the free end of the electric push rod 3033, and the bottom of the plurality of push plates 3031 passes through the inside of the rectangular groove 302 and is connected to the top surface of the adapter plate 3034. After the plurality of lamp structures 4 on the bearing plate 3 are placed at the designated position, the electric push rod 3033 is activated, and the adapter plate 3034 is moved horizontally towards one side, thereby synchronously applying tension to the plurality of push plates 3031, so that the plurality of arc-shaped plates 3032 matched with the semicircular grooves 3013 extrude and limit the outer side of the connecting end of the lamp structure 4 inserted into the semicircular groove 3013 from one side, thereby ensuring the stability of the lamp structure 4 during detection. In addition, based on the overall shape of the installation groove 301, the bearing plate 3 can be inserted into the aging test box 1 first, and then the lamp structure 4 can be placed, which is more suitable for the case where the space reserved at the top of the bearing plate 3 in the aging test box 1 is insufficient.
