[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Thus, a feature pointed out in this specification will be used to illustrate one feature of one embodiment of the present utility model, rather than implying that each embodiment of the present utility model must have the feature described. In addition, it should be noted that this specification describes many features. Although certain features may be combined together to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0039] The principle and structure of the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0040] The lamp bead test board is a circuit board specifically used to test the performance of LED lamp beads (light-emitting diodes). Such a test board usually includes some basic electronic components and circuits, such as a power supply interface, resistors, switches, etc., to provide a test environment for the LED lamp beads.

[0041] During the use of existing test equipment, the lamp bead test board is closely attached to the base through screws. In this way, every time a new lamp bead test board is replaced, the screws need to be disassembled and reassembled, resulting in low work efficiency, slow replacement speed, and the problem of screw thread slipping of the base after long-term use. Furthermore, the entire base cannot be repaired and needs to be replaced with a new test equipment.

[0042] To solve the above problems, referring to the attached Figures 1-3 , the present utility model proposes a test equipment, including a base 10. The side wall of the base 10 along the Y-axis direction is provided with at least one limiting groove 11 for placing a test board 1. Both sides of the limiting groove 11 along the X-axis direction are provided with fixing plates 12. Each fixing plate 12 facing the inner side wall of the limiting groove 11 is provided with at least one elastic device 13;

[0043] When the test board 1 is matched and placed in the limiting groove 11, the elastic device 13 tightly attaches the test board 1 to the base 10 through elastic action.

[0044] Among them, the test board 1 in this embodiment is exemplified by a lamp bead test board, and the same applies throughout the text. The top of the lamp bead test board is provided with a wiring terminal, and the wiring terminal can be connected to an upper computer or other devices through a cable, so that the upper computer or other devices can send instructions to test the lamp bead test board.

[0045] In this way, when a new LED test board needs to be replaced for testing, the present utility model does not need to reinstall the screws to replace the new LED test board. The user only needs to pinch or grasp the top of the LED test board and then pull it out from the limiting slot 11. Compared with the prior art where the LED test board is tightly attached to the base by screws, the present utility model does not need to reinstall the screws, thereby improving the working efficiency, increasing the replacement speed of the LED test board, and preventing the problem of screw thread slipping of the base 10, prolonging the service life of the base 10 and the testing equipment.

[0046] Moreover, when the new LED test board is inserted into the limiting slot 11, during the insertion process, the elastic device 13 arranged on the fixing plate 12 will be compressed, and then the elastic device 13 will generate a reaction force according to its own elasticity. This reaction force will make the LED test board tightly adhere to the bottom wall of the limiting slot 11, which is equivalent to the LED test board tightly adhering to the base 10. And the fixing plate 12 can prevent the LED test board from falling off the limiting slot 11.

[0047] Among them, to ensure that each testing equipment can test multiple LED test boards simultaneously to improve the testing efficiency or working efficiency of the testing equipment, refer to the attached Figure 3 , a plurality of limiting slots 11 are evenly arranged on both sides of the base 10 along the Y-axis direction.

[0048] Among them, to ensure that the LED test board can better adhere to the bottom wall of the limiting slot 11, or in other words, the LED test board can better adhere to the base 10, refer to the attached Figure 2 , two elastic devices 13 are arranged on the inner side wall of each fixing plate 12 facing the limiting slot 11 along the Z-axis direction.

[0049] It should be noted that three or more elastic devices 13 can also be arranged on the inner side wall of each fixing plate 12 facing the limiting slot 11 along the Z-axis direction, which is not limited herein.

[0050] In this way, two elastic devices 13 are arranged on the fixing plates 12 on both sides of each limiting slot 11 along the Z-axis direction, that is, both sides of each LED test board are tightly adhered to the bottom wall of the limiting slot 11 by the reaction forces generated by the two elastic devices 13 according to their own elasticity.

[0051] Among them, to ensure that when the elastic device 13 generates a reaction force through its own elasticity to make the LED test board tightly adhere to the bottom wall of the limiting slot 11, preventing the elastic device 13 from damaging the LED test board and increasing the defective rate of the LED test board, refer to the attached Figures 4-5 , the end of the elastic device 13 facing the limiting slot 11 is arc-shaped.

[0052] In other embodiments, to reduce the production cost of the testing equipment, refer to the attachedFigure 2 Along the X-axis direction, any two adjacent limiting grooves 11 share one fixing plate 12.

[0053] In this way, on the base 10 between any two adjacent limiting grooves 11 along the X-axis direction, a fixing plate 12 is provided. Then, a bolt 16 penetrates through the middle of the fixing plate 12, and the bolt 16 fixes the fixing plate 12 on the base 10. At this time, both sides of the fixing plate 12 along the X-axis direction will respectively block any two adjacent limiting grooves 11 along the X-axis direction. Then, the fixing plate 12 blocks both sides of the corresponding limiting groove 11 and is provided with two elastic devices 13 along the Z-axis direction towards the inner side of the limiting groove 11.

[0054] In this way, when it is necessary to replace the new fixing plate 12, only the bolt 16 needs to be disassembled to complete the replacement, improving the replacement efficiency of the fixing plate 12.

[0055] Among them, for the convenience of understanding, refer to the attached Figures 4-5 , the present utility model proposes a specific structure of the elastic device 13:

[0056] The elastic device 13 includes a housing 131, an elastic body 132, and a rolling member 133; among them, the elastic body 132 is preferably a compression spring, and the rolling member 133 is preferably a ball.

[0057] The housing 131 is embedded in the fixing plate 12. One side of the housing 131 facing the limiting groove 11 is provided with an opening, and the rolling member 133 is placed on the opening, and a part of the rolling member 133 protrudes from the housing 131;

[0058] An elastic body 132 is provided between the rolling member 133 and the inner side wall of the housing 131 away from the opening.

[0059] Among them, because the lamp bead test board needs to be tested under different temperature conditions during the test, refer to the attached Figure 3 , a heating device 14 is provided in the base 10. The heating device 14 includes a heating wire 141, and the heating wire 141 is electrically connected to the upper computer;

[0060] The base 10 is respectively provided with heating wires 141 corresponding to the limiting grooves 11 on the same side and along the X-axis direction.

[0061] In this way, when the test temperature of the lamp bead test board is higher than the ambient temperature of itself, the upper computer will energize the heating wire 141. Since the heating wire 141 is made of a high-resistance material, when the current passes through the heating wire 141, heat will be generated and transferred to the base 10, and the base 10 will then transfer the heat to the lamp bead test board in close contact with the base 10 to increase the temperature of the lamp bead test board.

[0062] It should be noted that the lamp bead test board is equipped with a temperature sensor, so that the upper computer can detect the temperature of the lamp bead test board in real time through the temperature sensor. When the test temperature is reached, the upper computer will cut off the power supply of the heating wire 141 to prevent the temperature of the lamp bead test board from continuing to rise.

[0063] Similarly, because the lamp bead test board needs to be tested under different temperature conditions during the test, refer to the appendix Figure 3 In the base 10, a cooling device 15 is further provided. The cooling device 15 includes a first pipe 151 and a second pipe 152 arranged along the X-axis direction, and a cooling medium flows in both the first pipe 151 and the second pipe 152; wherein, the cooling medium in this article is preferably water.

[0064] It should be noted that valves (not shown in the figure, the same throughout the text) are provided in both the first pipe 151 and the second pipe 152, and these valves are electrically connected to the upper computer.

[0065] In this way, when the test temperature of the lamp bead test board is lower than the ambient temperature where it is located, or when the latest test temperature of the lamp bead test board is lower than the previous test temperature, the upper computer will open the valves to allow the cooling medium to flow through the first pipe 151 and the second pipe 152, so as to take away the heat on the base 10, reduce the temperature of the base 10, and further reduce the temperature of the lamp bead test board in close contact with the base 10. And when the upper computer finds that the temperature of the lamp bead test board reaches the test temperature through the temperature sensor, it will close the valves to prevent the temperature of the lamp bead test board from continuing to drop.

[0066] In other embodiments (not shown in the figure), the first pipe 151 can be an inlet pipe, the second pipe 152 can be an outlet pipe, and one end of the first pipe 151 communicates with one end of the second pipe 152. The other end of the first pipe 151 is connected to the outlet of the cooling tower, and the other end of the second pipe 152 is connected to the inlet of the cooling tower. In this way, the cooling medium with a specified temperature in the cooling tower flows to the first pipe 151, and the cooling medium then flows from the first pipe to the second pipe 152. The cooling medium absorbs the heat of the base 10 to achieve the purpose of reducing the temperature of the base 10. Then, the cooling medium after absorbing the heat flows back to the cooling tower from the second pipe 152, and the cooling tower then cools the temperature of the flowing-back cooling medium to the specified temperature to achieve the cooling cycle.

[0067] Among them, the material of the base 10 is any one of aluminum, copper, and stainless steel. In this embodiment, it is taken as an example that the material of the base 10 is preferably aluminum; of course, the material of the base 10 can also be other materials with good thermal conductivity, which is not limited here.

[0068] Usage process of the test equipment of the present utility model: First, insert the lamp bead test board into the limiting groove 11 in a matching manner. At this time, the elastic device 13 on the fixing plate 12 corresponding to the limiting groove 11 will be compressed, resulting in an anti-thrust force generated by each elastic device 13 according to its own elasticity. This anti-thrust force will make the lamp bead test board closely adhere to the bottom wall of the limiting groove 11, which is equivalent to the lamp bead test board closely adhering to the base 10, ensuring that the temperature of the base 10 can be stably transferred to the lamp bead test board or the temperature of the lamp bead test board can be stably transferred to the base 10, thereby ensuring the test effect of the lamp bead test board.

[0069] Then, connect the wiring terminal of the lamp bead test board to the host computer through a cable, so that the host computer can send instructions to test the lamp bead test board.

[0070] Then, pull out the tested lamp bead test board from the limiting groove 11 and insert a new lamp bead test board to achieve a new round of testing.

[0071] Obviously, the embodiments described above are only a part of the embodiments of the present utility model, rather than all of them. The accompanying drawings show the preferred embodiments of the present utility model, but do not limit the patent scope of the present utility model. The present utility model can be implemented in many different forms.
