[0033] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.

[0034] This embodiment provides an LED lamp board aging auxiliary tooling, which is used to perform constant current and constant voltage aging tests on the LED lamp board 70, so as to verify the reliability and stability of the LED lamp board 70 in actual use.

[0035] As Figure 1 shown, this embodiment provides an LED lamp board aging auxiliary tooling with a cabinet body 10. An opening 11 of the cabinet body 10 is formed on one side, and an experimental chamber 13 is formed inside the opening 11 of the cabinet body. The inside of the experimental chamber 13 is used to install the LED lamp board 70, and then perform a constant current and constant voltage aging test on the LED lamp board 70.

[0036] In this embodiment, there is at least one lamp board fixing seat 20 inside the experimental chamber 13. The lamp board fixing seat 20 can install multiple LED lamp boards 70 to realize the test of multiple LED lamp boards 70.

[0037] As Figure 3 and Figure 4 shown, the surface of the lamp board fixing seat 20 has a plurality of installation slots 22, and each LED lamp board 70 can be correspondingly installed in the installation slot 22 to achieve fixation.

[0038] As Figure 2 and Figure 3 shown, in this embodiment, a probe assembly 40 is provided. Each probe assembly 40 corresponds to an installation slot 22, and the probe assembly 40 extends into the installation slot 22. When the LED lamp board 70 is installed in the installation slot 22, the contacts of the LED lamp board 70 are in contact with the probe assembly 40.

[0039] This embodiment also has a control component. The control component is connected to the probe assembly 40. The control component can independently control and detect multiple LED lamp boards 70, can perform constant current or constant voltage output on the LED lamp board 70, and effectively display the current and voltage of the LED lamp board 70, so as to perform a constant current and constant voltage aging test on the LED lamp board 70.

[0040] Specifically, as Figure 6 shown, the probe assembly 40 includes a spring probe 41, a probe guide seat 42, and a circuit board 43. The probe guide seat 42 is installed on the lower surface of the lamp board fixing seat 20. The spring probe 41 is arranged on the probe guide seat 42. The probe guide seat 42 guides the spring probe 41 from the lower surface of the lamp board fixing seat 20 into the installation slot 22 to contact the contacts of the LED lamp board 70.

[0041] The circuit board 43 is installed on the probe guide seat 42. The circuit board 43 is electrically connected to the spring probe 41 and the control component, and is used for processing test data.

[0042] In this embodiment, the lamp board fixing base 20 can quickly and effectively fix multiple LED lamp boards 70, and can reasonably and orderly arrange the LED lamp boards 70 and the spring probes 41 to ensure stable contact between the LED lamp boards 70 and the spring probes 41. At the same time, this embodiment can reasonably and effectively conduct independent tests on multiple LED lamp boards 70, avoiding chaos when there are many test objects, and greatly improving the efficiency and accuracy of the constant current and constant voltage aging test.

[0043] As Figure 5 shown, the installation card slot 22 is an installation groove with an upward opening. A through hole 221 that penetrates up and down is provided inside the installation card slot 22. The probe guiding seat 42 is arranged directly below the installation card slot 22, and the spring probe 41 extends through the through hole 221 into the interior of the installation card slot 22. When installing the LED lamp board 70, it is only necessary to directly place the LED lamp board 70 into the installation card slot 22, and the contacts of the installation card slot 22 will press on the upper part of the spring probe 41 and connect with the spring probe 41.

[0044] In one embodiment, in order to ensure that the LED lamp board 70 can be stably installed in the installation card slot 22, the shape of the installation card slot 22 is designed to be adapted to the shape of the LED lamp board 70. For example, in one embodiment, the LED lamp board 70 is a circular sheet structure, so the shape of the installation card slot 22 is circular, and the LED lamp board 70 can just be embedded into the installation card slot 22, which can effectively prevent the LED lamp board 70 from shifting and prevent the contacts of the LED lamp board 70 from detaching from the spring probe 41.

[0045] Furthermore, as Figure 5 shown, in one embodiment, a buckle 222 is provided on the side wall of the installation card slot 22. The buckle 222 is located at the top of the installation card slot 22 and extends into the installation card slot 22. In this way, when placing the LED lamp board 70, one end of the LED lamp board 70 can be first placed into the installation card slot 22 below the buckle 222, and then the other end of the LED lamp board 70 is pressed into the installation card slot 22. The buckle 222 is located above the LED lamp board 70 and presses on the LED lamp board 70, which can effectively prevent the LED lamp board 70 from detaching from the installation card slot 22.

[0046] In one embodiment, the buckle 222 can also be located at the horizontal position of the installation card slot 22. If the LED lamp board 70 is provided with a slot structure, the buckle 222 can also be snapped into the slot of the LED lamp board 70, which can prevent the LED lamp board 70 from rotating, and further prevent the contacts of the LED lamp board 70 from detaching from the spring probe 41.

[0047] In one embodiment, the buckle 222 can also be designed as a flip - up cover plate. The cover plate can be flipped above the LED lamp board 70. When the cover plate is flipped above the LED lamp board 70, it presses the LED lamp board 70 tightly into the installation slot 22, ensuring that the contacts of the LED lamp board 70 are tightly connected to the spring probes 41.

[0048] In this embodiment, a heat dissipation device is also provided. The heat dissipation device is installed on the lamp board fixing seat 20 and contacts the LED lamp board 70 to dissipate heat from the LED lamp board 70.

[0049] In one embodiment, the heat dissipation device can be heat dissipation fins 50. Both the heat dissipation fins 50 and the lamp board fixing seat 20 are in a long strip shape. After the LED lamp board 70 is installed on the lamp board fixing seat 20, the heat dissipation fins 50 are installed above the lamp board fixing seat 20 and the LED lamp board 70. At this time, the heat dissipation fins 50 press multiple LED lamp boards 70 tightly, ensuring sufficient contact with the LED lamp boards 70 while also pressing the LED lamp boards 70 tightly into the installation slot 22 to prevent the LED lamp boards 70 from falling off.

[0050] As Figure 5 and Figure 6 shown, in one embodiment, the installation slots 22 are arranged at intervals in a straight line along the extension direction of the lamp board fixing seat 20. The lamp board fixing seat 20 is provided with a communication groove 23 passing through multiple installation slots 22. The heat dissipation fins 50 are installed in the communication groove 23, which can press multiple LED lamp boards 70 tightly at the same time, and the heat dissipation fins 50 also have good installation stability.

[0051] As a further improvement, in one embodiment, magnetic attraction devices are respectively provided on the lamp board fixing seat 20 and the heat dissipation fins 50. In this way, when the heat dissipation fins 50 approach the lamp board fixing seat 20, a suction force is generated through the magnetic attraction devices to press the LED lamp board 70 tightly.

[0052] Specifically, as Figure 2 and Figure 5 shown, a plurality of first magnets 61 are arranged at intervals in the communication groove 23. The heat dissipation fins 50 are provided with a plurality of grooves 51, and second magnets 62 are arranged inside the grooves 51. The first magnets 61 and the second magnets 62 attract each other when approaching to fix the heat dissipation fins 50 and press the heat dissipation fins 50 tightly against the LED lamp board 70, ensuring that the contacts of the LED lamp board 70 are more tightly connected to the spring probes 41.

[0053] As Figure 1As shown in the figure, in this embodiment, a plurality of support plates 12 are provided in the cabinet body 10. The plurality of support plates 12 are arranged at intervals in the vertical direction. An experimental chamber 13 is formed between adjacent support plates 12. At least one lamp board fixing seat 20 is provided in each experimental chamber 13. The cabinet body 10 can install a plurality of lamp board fixing seats 20, and the plurality of lamp board fixing seats 20 are arranged in layers, enabling simultaneous aging detection of a large number of LED lamp boards 70. The experimental chamber 13 on each layer also facilitates observing the aging condition of the LED lamp board 70.

[0054] Specifically, as Figure 2 and Figure 3 shown, in one embodiment, a plurality of brackets 21 are provided below the lamp board fixing seat 20. The lamp board fixing seat 20 is installed above the support plate 12 through the brackets 21. A receiving space is formed between the lamp board fixing seat 20 and the support plate 12. The probe assembly 40 is arranged in the receiving space. The receiving space provides space for the installation of the probe assembly 40 and facilitates the wiring layout of the probe assembly 40, which is beneficial for the installation or maintenance of the tooling. Of course, the lamp board fixing seat 20 can also be directly fixed on the inner wall of the cabinet body 10 or installed on the inner wall of the cabinet body 10 through a support structure.

[0055] In one embodiment, the cabinet body 10 can be a drawer cabinet. A cabinet opening 11 is provided on one side of the cabinet body 10. The support plate 12 is slidably connected to the inner wall of the cabinet body 10. The support plate 12 can be pulled out towards the cabinet opening 11 to facilitate pulling out the lamp board fixing seat 20, thereby conveniently installing or removing the LED lamp board 70.

[0056] To facilitate pulling out the support plate 12, as Figure 1 shown, a handle 14 is provided on the side of the support plate 12 close to the cabinet opening 11.

[0057] In this embodiment, the control component includes a control panel 30 provided above the cabinet body 10. A plurality of control buttons 31 and a voltage and current display meter 32 are provided on the control panel 30. The control buttons 31 and the voltage and current display meter 32 correspond to each probe assembly 40 one by one. The control buttons 31 are used to independently control the circuit on / off of each LED lamp board 70, and the voltage and current display meter 32 is used to independently display the current and voltage data of each LED lamp board 70, so as to perform independent constant current and constant voltage aging tests on each LED lamp board 70.

[0058] Specifically, as Figure 7 shown, there is an inclined surface in the front direction of the top of the cabinet body 10. The control panel 30 is installed on the inclined surface. The control buttons 31 include switch buttons, etc. These switch buttons and the display screen are neatly arranged on the inclined surface, facilitating operation and observation by workers.

[0059] Of course, the control panel 30 can also be an integrated intelligent touch screen, which controls and displays each detected LED light board 70 to realize the intelligence of detection.

[0060] The control component of this application also includes electronic components such as a controller. The controller is electrically connected to the control panel 30 and the circuit board 43 of the probe component 40, and the controller is used to effectively control the current and voltage required in the constant current and constant voltage aging test.

[0061] The strip-shaped design of the lamp board fixing seat 20 in this embodiment enables the LED light boards 70 to be arranged in a straight line on the lamp board fixing seat 20, facilitating the observation of multiple lamp board fixing seats 20. The layered design of the cabinet 10 reasonably and effectively arranges the installation of multiple lamp board fixing seats 20, enabling the installation of a large number of lamp board fixing seats 20. Each probe component 40 is arranged in a line below the lamp board fixing seat 20, facilitating the wiring of the probe component 40. The installation of a large number of lamp board fixing seats 20 is also in an orderly manner without any messy phenomenon, and the arrangement of the probe component 40 is also beneficial to the heat dissipation of the probe component 40 itself.

[0062] The pull-out design of the support plate 12 in this embodiment can pull the lamp board fixing seat 20 out of the cabinet 10 when installing or disassembling the LED light board 70, providing space for the work of installing or disassembling the LED light board 70, greatly facilitating the aging detection work of the LED light board 70. The LED light board aging auxiliary tooling provided in this embodiment has significant advantages in the constant current and constant voltage aging test link of the LED light board 70 and has very good application value.
