[0028] The left - right, up - down positions of the components shown in the drawings are just a layout method, and the specific positions are set according to specific needs.
[0029] In one embodiment, as Figures 1 - 5As shown in the figure, an aging platform for testing LED bulbs includes a base plate 100, a test table plate component 200, a rotating motor 300, and an upper cylindrical cover 800. The rotating motor 300 is arranged at the center of the upper end surface of the base plate 100, and the output end of the rotating motor 300 is connected to a column part 700.

The lower support plate 210 is fixed on the column part 700, and the test plate 220 is arranged on the lower support plate 210. A plurality of circumferentially distributed mounting grooves 230 are formed along the edge of the test plate 220, and a plurality of bulb bodies 500 can be respectively clamped inside the mounting grooves 230 and electrically connected to fixed electrical connection seats 240 arranged in the mounting grooves 230. The polygonal column part 260 is fixed on the column part 700 and corresponds to the mounting grooves 230 one by one; a fault induction piece 270 for sensing the performance parameters of the bulb body 500 during aging testing is arranged on each side of the polygonal column part 260; the upper cylindrical cover 800 is arranged above the test table plate component 200 and can cover the test table plate component 200 from above. A height adjustment component for adjusting the position of the upper cylindrical cover 800 on the column part 700 is arranged at the top of the column part 700; a plurality of avoidance openings 830 corresponding to the mounting grooves 230 one by one are formed on the outer wall of the upper cylindrical cover 800. A sealing cover plate 840 is arranged at the avoidance opening 830, and a rotary opening component connected to the sealing cover plate 840 is arranged on the outer wall of the upper cylindrical cover 800. The end of the rotary opening component away from the sealing cover plate 840 extends from the top of the upper cylindrical cover 800 to the inside of the upper cylindrical cover 800. A plurality of pushing components 280 corresponding to the mounting grooves 230 one by one are arranged on the outer wall of the polygonal column part 260. The pushing components 280 are used to push the bulbs out of the mounting grooves 230 and act on the end of the rotary opening component extending into the upper cylindrical cover 800; a plurality of collecting grooves 900 are also arranged on the base plate 100, and the collecting grooves 900 are used to collect the bulb bodies 500 removed from the mounting grooves 230;
[0030] Among them, the fault induction sheet 270 is an integrated sensor composed of multiple sensors, and the fault induction sheet 270 senses the performance parameters of the bulb body 500 during the aging test, including luminous brightness, color temperature, light efficiency, etc.; the fault induction sheet 270 belongs to the prior art and will not be elaborated here; before the test of the bulb body 500, the height adjustment component drives the upper cylindrical cover body 800 to move upward, and the upper cylindrical cover body 800 moves away from the test bench component 200. The test bench component 200 is exposed on the outside and is convenient for pushing the bulb body 500 to be tested into the installation groove body 230 correspondingly, and making the bulb body 500 electrically connected to the corresponding fixed electrical connection seat 240; after the installation of the bulb body 500 is completed, the height adjustment component drives the upper cylindrical cover body 800 to move downward and cover the test bench component 200 and the bulb body 500 thereon. The bulb body 500 is in a closed space and can be tested by simulating the working environment to reduce the influence of the external environment on the aging test; the fixed electrical connection seat 240 is powered on and starts the aging test on the bulb body 500; among them, the test method for aging the bulb body 500 can be completed by the prior art and will not be elaborated here; the fault induction sheet 270 senses that a certain bulb body 500 has abnormal phenomena such as dead lamp, dim lamp, flicker or color deviation during the test; the rotation motor 300 starts to work and drives the test bench component 200 and the upper cylindrical cover body 800 to rotate. The bulb body 500 rotates with the test bench component 200, and the bulb body 500 with abnormal phenomena rotates to a position corresponding to one of the collection tank bodies 900. The multiple collection tank bodies 900 correspond one by one to the abnormal phenomena of the bulb body 500; the rotation motor 300 stops working and the corresponding pushing component 280 starts to work. The pushing component 280 pushes the bulb body 500 and makes the bulb body 500 move along the installation groove body 230 towards the collection tank body 900, and the bulb body 500 is disconnected from the fixed electrical connection seat 240; before pushing the bulb body 500, the pushing component 280 first acts on the end of the rotation opening component extending into the upper cylindrical cover body 800. The rotation opening component drives the corresponding sealing cover plate 840 to rotate upward and away from the avoidance port 830, so that the avoidance port 830 is opened; therefore, the pushing component 280 can push the bulb body 500 out from the avoidance port 830 and move it onto the corresponding collection tank body 900. Each collection tank body 900 collects the bulb bodies 500 with the same abnormal phenomenon, which is convenient for subsequent maintenance personnel to identify; when pushing out the bulb body 500 with abnormal phenomena, other bulb bodies 500 can be in the aging test state. Since only the corresponding avoidance port 830 is opened when the bulb body 500 is pushed out, the influence on the normal aging test of other bulb bodies 500 can be reduced when dealing with the bulb body 500 with abnormal phenomena.
[0031] In one embodiment, as Figures 1 - 5As shown, an active electrical connection base 250 is provided inside each mounting groove body 230. The active electrical connection base 250 is slidably engaged with the inner wall of the mounting groove body 230 and can slide out from the notch of the mounting groove body 230. The side of the active electrical connection base 250 facing the fixed electrical connection base 240 has an electrical plug, and the lamp body 500 can be plugged onto the active electrical connection base 250 from the top. In the actual application process of the embodiment of the present invention, after the lamp body 500 is plugged onto the active electrical connection base 250, the lamp body 500 is electrically connected to the active electrical connection base 250. The active electrical connection base 250 is pushed into the mounting groove body 230 and cooperates with the jack on the fixed electrical connection base 240 through the electrical plug, so as to realize the electrical connection between the lamp body 500 and the fixed electrical connection base 240. When disassembling the lamp body 500, only need to push the component 280 to push the active electrical connection base 250 towards the notch of the mounting groove body 230, and the disconnection between the lamp body 500 and the fixed electrical connection base 240 can be automatically completed.
[0032] In one embodiment, as Figure 1 shown, the height adjustment component includes an upper bracket 710 and at least one adjustment cylinder part 600. The upper bracket 710 is fixed to the top of the column part 700 and the adjustment cylinder part 600 is arranged on the upper bracket 710. The output end of the adjustment cylinder part 600 is connected to the top wall of the upper cylindrical cover body 800. Among them, the adjustment cylinder part 600 can be an electric telescopic rod, a hydraulic cylinder or a cylinder and other telescopic components, as long as it can realize the movement of the upper cylindrical cover body 800 along the column part 700 and maintain stability, and can be selected according to actual applications.
[0033] In one embodiment, as Figures 1 - 5As shown, the rotary opening component includes a lifting unit 850 and a bearing unit 860. One end of the lifting unit 850 is fixedly connected to the sealing cover plate 840, and the other end of the lifting unit 850 extends to the top of the upper cylindrical cover 800 and is rotatably connected to the top wall of the upper cylindrical cover 800. The bearing unit 860 is arranged on the top of the upper cylindrical cover 800, and the bearing unit 860 can vertically slide on the top wall of the upper cylindrical cover 800 in a manner of bearing elastic damping. The top of the lifting unit 850 is connected to the top of the bearing unit 860. When the upper cylindrical cover 800 covers the test table plate component 200, the lower end of the bearing unit 860 is connected to the pushing component 280, and when the pushing component 280 pushes the bulb body 500, the pushing component 280 can drive the bearing unit 860 to move vertically. In the actual application process of the embodiment of the present invention, in the initial state, the sealing cover plate 840 is inside the avoidance opening 830 and seals the avoidance opening 830. After the bulb body 500 is installed, the upper cylindrical cover 800 moves downward to cover the test table plate component 200. At this time, the avoidance opening 830 is at the notch of the installation groove body 230, and the pushing component 280 and the end of the bearing unit 860 extending into the upper cylindrical cover 800 are in a connected state. Before the pushing component 280 pushes the bulb body 500 to move, the pushing component 280 first acts on the bearing unit 860 and makes the bearing unit 860 move upward. The bearing unit 860 drives the lifting unit 850 to rotate upward, and the rotating lifting unit 850 drives the sealing cover plate 840 to disengage from the avoidance opening 830, so that the avoidance opening 830 is opened, facilitating the pushing component 280 to push the bulb body 500 out from the notch of the installation groove body 230.
[0034] In one embodiment, as Figures 1 - 5As shown, the opening unit 850 includes an opening rotating shaft 851 and an opening support arm 852. Both ends of the opening rotating shaft 851 are rotatably arranged on the top wall of the upper cylindrical cover 800 through supports, and an opening gear 853 is arranged on the opening rotating shaft 851. One end of the opening support arm 852 is connected to the outer surface of the sealing cover plate 840, and the other end is fixedly connected to the opening rotating shaft 851. The bearing unit 860 includes a bearing vertical rod 861 and a bearing extension rod 862. The bearing vertical rod 861 vertically slides through the top wall of the upper cylindrical cover 800, and the top of the bearing vertical rod 861 is connected to the top of the upper cylindrical cover 800 through a damping return spring 864. A rack portion 863 meshing with the opening gear 853 is also arranged on the bearing vertical rod 861. When the upper cylindrical cover 800 covers the test bench plate component 200, the lower end of the bearing vertical rod 861 can be connected to the pushing assembly 280. In the actual application process of the embodiment of the present invention, when the pushing assembly 280 starts to work, it first drives the bearing vertical rod 861 to move upward. The upward moving bearing vertical rod 861 makes the opening rotating shaft 851 rotate through the meshing of the rack portion 863 and the opening gear 853. Then the opening support arm 852 rotates and drives the sealing cover plate 840 to disengage from the avoidance opening 830, so that the avoidance opening 830 can be opened before the bulb body 500 is pushed out, facilitating the pushing out of the bulb body 500. When the pushing assembly 280 resets, under the elastic force of the damping return spring 864, the bearing vertical rod 861 moves downward and the opening rotating shaft 851 rotates back. Therefore, the opening support arm 852 and the sealing cover plate 840 move back to the initial position, and the avoidance opening 830 is sealed by the sealing cover plate 840.
[0035] In one embodiment, as Figures 1 - 5 shown, the pushing assembly 280 includes a pushing cylinder portion 281 and an upper supporting rod 283. One end of the pushing cylinder portion 281 is fixed on the side wall of the polygonal column portion 260, and a pushing block 282 is arranged at the other end of the pushing cylinder portion 281.

The lower end of the bearing vertical rod 861 is provided with an inclined upward bearing extension rod 862 facing the side of the polygonal column portion 260. When the upper cylindrical cover 800 covers the test bench plate component 200, the top roller abuts against the end of the bearing extension rod 862 far from the bearing vertical rod 861. In the actual application process of the embodiment of the present invention, the pushing cylinder portion 281 drives the pushing block 282 and the upper supporting rod 283 to move towards the notch of the installation groove body 230 through elongation. The top roller on the upper supporting rod 283 gradually jacks up the bearing extension rod 862, so that the bearing vertical rod 861 moves upward. The pushing block 282 contacts the side portion of the movable electrical connection seat 250 and pushes the movable electrical connection seat 250 to move along the installation groove body 230. The pushing block 282 is made of insulating material.

[0037] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, the collecting tank body 900 is fixed on the base plate 100 through the lower bracket 910, and a control panel part 400 is further provided on the side of the base plate 100. A second pressure sensing ball 920 is provided at the notch of the collecting tank body 900 facing the test table plate component 200, and a plurality of first pressure sensing balls 290 corresponding to a plurality of mounting grooves 230 are provided at the edge of the test table plate component 200; the first pressure sensing ball 290, the second pressure sensing ball 920, the rotating motor 300, the fault sensing piece 270 and the pushing component 280 are all electrically connected to the control panel part 400; in the actual application process of the embodiment of the present invention, when the fault sensing piece 270 senses a certain bad phenomenon of the corresponding bulb body 500, the control panel part 400 starts to control the rotating motor 300 to work and drives the second pressure sensing ball 920 and the first pressure sensing ball 290 on the corresponding collecting tank body 900 to be energized; the rotating motor 300 drives the test table plate component 200 to rotate, and when the energized first pressure sensing ball 290 rotates to contact the energized second pressure sensing ball 920, the second pressure sensing ball 920 and the first pressure sensing ball 290 generate induction signals at the same time, and the control panel part 400 controls the corresponding pushing component 280 to start working and the rotating motor 300 stops rotating, so that the bulb body 500 with the bad phenomenon corresponds to the collecting tank body 900, and the pushing component 280 can push the bulb body 500 with the bad phenomenon into the corresponding collecting tank body 900, so as to realize the classified cleaning of the bulb body 500 in the bad state.
[0038] In one embodiment, as Figure 1 、 Figure 2 and Figure 4As shown, the outer diameter of the lower support disk 210 is the same as that of the upper cylindrical cover 800, and the outer diameter of the test disk 220 is equal to the inner diameter of the upper cylindrical cover 800. A plurality of circumferentially distributed light-shielding plates 820 are provided on the side wall of the upper cylindrical cover 800, and two adjacent light-shielding plates 820 form a cavity. When the upper cylindrical cover 800 covers the test bench disk component 200, the plurality of cavities respectively cover the outside of the corresponding lamp bodies 500. In the actual application process of the embodiment of the present invention, the upper cylindrical cover 800 covers the test bench disk component 200, and the plurality of light-shielding plates 820 separate the plurality of lamp bodies 500 from each other, so as to reduce the mutual influence during the aging test of the plurality of lamp bodies 500.
[0039] The above embodiments provide an aging platform for testing LED bulbs. Before the test, the tester inserts the bulb body 500 onto the movable electrical connection seat 250 and pushes the movable electrical connection seat 250 into the interior of the installation groove body 230. The movable electrical connection seat 250 is electrically connected to the fixed electrical connection seat 240. The adjusting cylinder part 600 drives the upper cylindrical cover body 800 to move downward and cover the test table plate component 200, so that multiple bulb bodies 500 are in a relatively sealed environment. Multiple regulators 810 can adjust factors such as temperature and humidity in this environment that affect the aging test of LED bulbs. When the fault induction piece 270 senses that a corresponding bulb body 500 is in a certain abnormal phenomenon, the control panel part 400 starts to control the rotation motor 300 to work and drives the second pressure induction ball 920 and the first pressure induction ball 290 on the corresponding collection tank body 900 to be energized. The rotation motor 300 drives the test table plate component 200 to rotate. When the energized first pressure induction ball 290 rotates to contact the energized second pressure induction ball 920, the second pressure induction ball 920 and the first pressure induction ball 290 simultaneously generate induction signals. The control panel part 400 controls the corresponding pushing component 280 to start working and the rotation motor 300 stops rotating. Then, the bulb body 500 with the abnormal phenomenon corresponds to the collection tank body 900. The pushing cylinder part 281 starts to work and pushes the pushing block 282 and the upper supporting rod 283. The upper supporting rod 283 acts on the bearing extension rod 862 and makes the bearing vertical rod 861 move upward. The upward moving bearing vertical rod 861 makes the opening shaft 851 rotate through the meshing of the rack part 863 and the opening gear 853. Then, the opening arm 852 rotates and drives the sealing cover plate 840 to disengage from the avoidance opening 830, so that the avoidance opening 830 can be opened before the bulb body 500 is pushed out. The pushing block 282 pushes the movable electrical connection seat 250 and makes the movable electrical connection seat 250 disconnect from the fixed electrical connection seat 240. The bulb body 500 is pushed out of the installation groove body 230 and removed from the installation groove body 230, so that the bulb body 500 moves into the corresponding collection tank body 900. Each collection tank body 900 collects the bulb bodies 500 with the same abnormal phenomenon, which is convenient for subsequent maintenance personnel to identify. When the bulb body 500 with the abnormal phenomenon is pushed out, other bulb bodies 500 can be in the aging test state. Since only the corresponding avoidance opening 830 is opened when the bulb body 500 is pushed out, the normal aging test of other bulb bodies 500 can be reduced when dealing with the bulb body 500 with the abnormal phenomenon.
