Among them, the object to be tested has a front surface: 4ΐσ'—back surface and multiple sides. In addition, the mechanical arm can be married (unfinished or true. Empty plate (not shown)) The _ object 4 〇〇 is placed in the backlight module trace. The backlight module _. includes: the storage G 11G, the first illuminating member i2G, the number of the first reflecting member 130, the sentence light The board 14 〇 and a transparent blocking plate 15 〇. The storage opening (10) is disposed on the top surface of the backlight module 100 and communicates with the external environment. The illuminating object 400 can be placed in the backlight module 1 ,, the first illuminating The 12-inch light-emitting element is a ring-shaped light-emitting element. In detail, the first light-emitting element 12G includes a plurality of light-emitting diodes emitting diode 'LED' bulbs, and the light-transmitting two-pole bubble ring is disposed at the edge of the storage opening 11〇. The first reflecting member 130 surrounds each side surface 42 of the object to be tested 4, and the reflecting surfaces of the first reflecting members 13G respectively have an acute angle with each side surface 42 of the object to be tested. In order to make the backlight 121 emitted by the first illuminating member 120 uniformly projected on the back surface 430 of the object to be tested 400, the backlight module 100 further includes a light concentrating plate 14 〇, and the light absorbing plate 14 让 is used for backlighting. The source 121 generates refraction or scattering. M421499 In order to prevent the object to be tested 400 from falling into the positive light module 200, the bottom of the backlight module loo further includes a transparent barrier plate 150, and the transparent barrier plate 150 prevents the object to be tested 400 from falling. The positive light module is inside the 2 ,, on the one hand, it allows light to pass through. The positive light module 200 includes a second light emitting element 210 and a second light reflecting element 22. The first light emitting element 210 emits a positive light source 211. The positive light source 211 of the embodiment is a coaxial light source having the characteristics of parallel light. The second reflecting member 22 is disposed only on the projection path of the positive light source 211, and reflects and guides the positive light source 211 to the first reflecting member to change the traveling path of the positive light source 211. The second reflection of the embodiment The piece 22 is a semi-transparent and semi-reflective reflecting element, so that the intensity of the positive light source 211 reflected to the first reflecting member 13A is half the intensity of the i-light source 211 emitted by the second illuminating member 21. However, it is not limited thereto. In other embodiments, the second reflecting member 22A may also adopt other reflective elements having a reflective transmittance. The camera module 300 includes an imaging member 310 and a third reflecting member 32A. The camera member 310 includes a lens 311 and a charge coupled component 312. The charge coupled device 312 captures an image through the lens 311. The third reflecting member 32 is used to change the traveling path of the positive light source 2 and the backlight 121. Therefore, the third reflecting member 32 is configured to project an image of the front surface 410 of the object to be tested 4 and an image of each side surface 420 of the object to be tested 4 401 formed on the first reflecting member 13 through the lens 311 to the electric charge. Coupling element 312. Next, the projection path of the backlight 121 and the positive light source 211 and the captured image will be described. Please refer to "Figure 4" to "Figure 6". "Figure 4" is the projection path of the positive light source and the backlight of "1B", and "5th" is "4th". The backlight schematic of the positive light source '"Fig. 6" is a schematic image capture of the object to be tested in "1B". It can be seen from Fig. 4 that the first light-emitting member 12 〇 projects the backlight 121 from the back surface 430 of the object to be tested 400. Therefore, the object to be tested 400 blocks the backlight 121, and the shadow is the object to be measured. The front of the .400 is a 41-inch round temple (eg "6th round"; so far):. The second illuminating member 210 projects the positive light source 211 to the second reflecting member 22 〇. Next, the second reflection member 220. The traveling path of the positive light source 2α1 is changed and half of the first L is guided to the first reflecting member 13A. Then, the first reflecting member m adds the positive light source to the side; the side of the object to be tested is 420, and the side of the object to be tested is 42 〇 _ the positive light source 211 to generate a shadow 'this shadow is the object to be tested 4轮 〇〇 〇 〇 〇 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( How the light source 2ij produces a backlight effect "The TM shown by the reference tooth v is projected to one of the first reflection members 13. The second 130 projects the positive light source 211 onto one of the sides 42 of the object to be tested. - the first reflecting member 13 of the side surface 420 projects the image to the camera module 300, and the result of the image is as if the person is standing on the other side of the object to be tested, and the object to be tested is observed. The light source is called an optical inspection method for performing the touch exposure on the opposite side of the object to be tested, and the first reflection 2, the second reflection member and the third reflection member are used to change the path of the wire, so that the path of the light is required to be 2 The route travels. This makes it possible to reduce the size of the optical inspection system by the arrangement of the aging group and the camera group. M421499 The number of cameras used is small. In addition, the second The positive light source emitted by the illuminating member is a coaxial light source having parallel light characteristics. Since the light of the coaxial gauge is less divergent, the high light contrast can be generated when the positive light source is projected onto the side of the object to be tested via the first reflecting member. The rim image of the side object is used to measure the dimensional accuracy of the object to be tested.
