These terms are primarily used to distinguish one component from another, or one signal from another.

[0031] Please see Figure 1-5 This is an evaluation table according to this embodiment, used for inspecting workpieces, wherein the evaluation table includes:
[0032] The support 1 is composed of multiple plates 11 connected together. The multiple plates 11 enclose a detection space 111, which is used for placing workpieces.
[0033] Lighting mechanism 2 is installed on the top of bracket 1. Lighting mechanism 2 includes lighting box 21, lamp 22, and top cover plate 23. The bottom of lighting box 21 is provided with a first opening and the top of lighting box 21 is provided with a second opening. Lamp 22 is installed at the first opening and top cover plate 23 is installed at the second opening. Lamp 22 has a light-emitting surface and a back plate surface arranged opposite to each other. The light-emitting surface of lamp 22 is arranged towards the detection space 111 and the back plate surface of lamp 22 is arranged towards the top cover plate 23.
[0034] The lamp 22 is set to cover the detection space 111 along the projected area.
[0035] For the above structure, during installation, first select the corresponding size of board 11, and build the actual testing space 111 with the help of multiple boards 11 according to the required testing scenario. Then, build the lighting mechanism 2 at the top of the testing space 111, so that the lighting mechanism 2, with the support of the bracket 1, can achieve full coverage of the top area of the testing space 111, and the lamps 22 in the lighting mechanism 2 can fully cover the bottom side of the testing space 111 along the projection surface.
[0036] With the above structure, during use, the operator only needs to place the workpiece to be inspected from the open side of the bracket 1 into the inspection space 111 enclosed by the bracket 1, and turn on the lamp 22 in the lighting mechanism 2 so that the lamp 22 provides omnidirectional illumination from the top of the workpiece. The operator then performs the inspection operation on the workpiece from the open side of the bracket 1, using the top lighting mechanism 2 for illumination, and using the enclosure of the bracket 1 to avoid interference from the external environment.
[0037] During the aforementioned use, the semi-enclosed design of the plate 11 of the bracket 1 avoids interference from external factors on the operator's inspection. Simultaneously, because the lamp 22 is fully covered at the top within the semi-enclosed space, an excellent lighting inspection environment is created, helping to improve the operator's accuracy in inspecting the workpiece. It is worth noting that, due to the top cover 23 on the top of the lighting mechanism 2, the operator can replace the internal components of the lighting mechanism 2 by opening the cover 23, improving maintenance convenience.
[0038] Furthermore, the lighting box 21 of the support 1 and the lighting mechanism 2 is made of steel plate with a baked enamel finish. Compared to the existing structures that mostly use wooden boards, the baked enamel steel plate in this embodiment is odorless and minimizes the impact on the test results. Similarly, compared to other glass structure construction scenarios, this embodiment avoids the refraction and transmission of light through glass, reducing the instability of the lighting environment.
[0039] Furthermore, the lamp 22 is configured as a shadowless lamp with a rectangular projection surface. Specifically, in this embodiment, the plate 11 in the bracket 1 used to place the workpiece is also configured as a corresponding rectangular surface, so that the lamp 22 can uniformly cover the entire rectangular surface and avoid detection errors caused by uneven light.
[0040] Furthermore, one of the plates 11 of the bracket 1 is provided with a window opening, which is positioned towards the detection space 111. A movable door panel 13 is installed at the window opening, and the movable door panel 13 is rotatably mounted on the corresponding plate 11 via a door hinge 131. With the above structure, the movable door panel 13 can rotate relative to the plate 11 to open and close one side of the door panel 11, facilitating the handling and transfer of workpieces while maintaining the integrity of the space.
[0041] Furthermore, the bracket 1 and the lighting mechanism 2 together enclose the detection space 111 into a rectangular space with only one open side. Simultaneously, a crossbeam 12 is installed on the top of the open side of the detection space 111 on the bracket 1, and the crossbeam 12 abuts against the bottom of the lighting box 21 of the lighting mechanism 2. Through this structure, the structural strength of the bracket 1 is effectively guaranteed by the organization of the rectangular space, and the presence of the crossbeam 12 provides stable support for the lighting mechanism 2, resulting in a more stable lighting effect.
[0042] Furthermore, ventilation holes 231 are provided on the top cover plate 23. These ventilation holes 231 are designed in an oblong shape, and there are multiple ventilation holes 231 arranged in a rectangular array on the top cover plate 23. Specifically, the multiple ventilation holes 231 evenly cover the surface of the top cover plate 23, which allows the top cover plate 23 to have a lighter weight, avoiding excessive pressure on the bracket 1. Secondly, it can also quickly dissipate heat emitted upwards from the back panel of the lamp 22, indirectly improving the stability of the lamp 22 during use.
[0043] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.
