[0026] Please see Figures 1 to 5An embodiment of the present invention provides a visual inspection device for detecting a heat spreader. The visual inspection device for detecting a heat spreader includes a base plate 300, a first beam splitter 100, a second beam splitter 200, a light-emitting component 400, a reflective component 500, and a camera detection module 600. The base plate 300 is provided with a through-hole 301 that extends vertically. The first beam splitter 100 includes a first beam splitter 110 and a first fixing base 120. The first fixing base 120 is disposed at the top of the base plate 300 and located on one side of the through-hole 301 along a first direction, and is connected to the first beam splitter 110. The first beam splitter 110 is tilted and is at least partially located above the opening 301. Two second beam splitting assemblies 200 are provided. Each second beam splitting assembly 200 includes a second beam splitter 210, a second fixing base 220, and a rotating member 230. The rotating member 230 is rotatably mounted on the top of the base plate 300 in a vertical direction, and the second fixing base 220 is rotatably connected to the rotating member 230 in a third direction. The second fixing bases 220 of both second beam splitting assemblies 200 are located on one side of the opening 301 along a first direction, and are respectively located on the first fixing base 120 along a second direction. The first beam splitter 110 is tilted to both sides of the first beam splitter 110, and the second beam splitter 210 is at least partially located above the opening 301. The tilt direction of the first beam splitter 110 forms an angle with the tilt direction of the second beam splitter 210 of the two second beam splitter components 200. The light-emitting component 400 is located at the top of the base plate 300, on the other side of the opening 301 along the first direction, and faces the first beam splitter 110 and the second beam splitter 210. Two reflective components 500 are provided; each reflective component 500 includes an adjustment component 510 and a reflector 520. The reflectors of the two reflective components 500... The mirrors 520 are located on the side of the two second beam splitters 210 away from the port 301. The mirrors 520 are tilted upwards and are rotatably connected to the adjustment assembly 510. The adjustment assembly 510 is located at the top of the base plate 300 and can move the mirrors 520 along the first direction, the second direction and the vertical direction. There are three camera detection modules 600, which are located above the first beam splitter 110 and the two second beam splitters 210 respectively. The first direction, the second direction and the third direction are all horizontal. The first direction and the second direction are perpendicular to each other and each has an angle with the third direction.
[0027] The temperature distribution plate 10 to be tested can be placed below the inlet 301; the light-emitting component 400 is positioned facing the first beam splitter 110 and the second beam splitter 210, so that the light-emitting component 400 can emit light and illuminate the first beam splitter 110 and the second beam splitter 210. The first beam splitter 110 and the second beam splitter 210 are both tilted, and at least part of the first beam splitter 110 and the second beam splitter 210 are located above the inlet 301, so that the light-emitting component can be illuminated by the first beam splitter 110 and the second beam splitter 210. The light emitted from the 400 beam splitter is reflected onto the temperature distribution plate 10 to be tested. Because the tilt direction of the first beam splitter 110 is at an angle to the tilt directions of the two second beam splitters 210, the angles of the light reflected by the first beam splitter 110 and the second beam splitter 210 are different, thus enabling illumination of the temperature distribution plate 10 from multiple directions. The camera detection module 600, located above the first beam splitter 110, can detect the upper end of the temperature distribution plate 10 from above, through the first beam splitter 110. The second beam splitter 210 acts as a filter, allowing the camera detection module 600 located above the second beam splitter 210 to detect the temperature distribution plate 10 from an oblique angle via the reflector 520. The second beam splitter 210 also acts as a filter, enabling the three camera detection modules 600 to detect the temperature distribution plate 10 from different angles, resulting in better detection performance. The second beam splitter 210 is connected to the second fixed base 220, which can rotate relative to the rotating member 230 around a third direction. The rotating component 230 can rotate around the third direction, and can rotate around the vertical direction, so as to drive the second beam splitter 210 to rotate around the vertical direction, thereby adjusting the tilt angle of the second beam splitter 210 and adjusting the angle at which light is reflected from the second beam splitter 210 to the temperature distribution plate 10 to be tested. The adaptability is good. The reflector 520 can be moved along the first direction, the second direction and the vertical direction by the adjusting component 510 to adapt to the second beam splitter 210. The adaptability is good and the detection effect can be guaranteed.
[0028] Reference Figure 1 In some embodiments of the present invention, the angle between the tilt direction of the first beam splitter 110 and the first direction is greater than 0° and less than 90°, and it is perpendicular to the second direction, so that the light emitted by the light-emitting component 400 can be reflected in a vertically downward direction through the first beam splitter 110 to illuminate the top of the temperature equalization plate 10 to be tested; the angle between the tilt direction of the second beam splitter 210 and the first and second directions is greater than 0° and less than 90°, so that the light emitted by the light-emitting component 400 can be reflected in a tilted downward direction through the second beam splitter 210 to illuminate both sides of the temperature equalization plate 10 to be tested.

[0030] The extension direction of the first side 302 and the extension direction of the second side 303 are both horizontal. The extension direction of the first side 302 is set in the same direction as the second direction to reduce the obstruction of the light reflected by the first beam splitter 110. The extension direction of the second side 303 has an angle between the first direction and the second direction to reduce the obstruction of the light reflected by the second beam splitter 210.
