Detailed Implementation

[0028] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0029] Example 1:

[0030] Provided such as Figure 1-7An optical inspection device is shown, comprising: a support housing 1, an air flotation platform 2, a measuring housing 3, and a computer 4. The support housing 1 supports the entire optical inspection device; the air flotation platform 2 is used to place the product under test; the measuring housing 3 is used to measure the product under test; and the computer 4 is electrically connected to a spectrometer and processes the data transmitted by the spectrometer.

[0031] like Figure 1 As shown, the support housing 1 includes a support bracket 11, an extension bracket 12, and support legs 13. The support bracket 11 is used to support the air flotation platform 2, the measuring housing 3, and the computer 4. The extension bracket 12 is located around the air flotation platform 2 and is rotatably connected to the air flotation platform 2. It is equipped with a fixed support rod, which allows the extension bracket 12 to be unfolded or folded up. The extension bracket 12 can be adjusted according to the size of the product being tested. When the extension bracket 12 is unfolded, it can test large-sized products. When the extension bracket 12 is folded up, it can test small-sized products and reduce the space occupied.

[0032] like Figure 2 As shown, the air flotation platform 2 includes a platform 21 and an air pipe. An air hole 22 is provided on the platform 21, and the air pipe is located below the platform 21 and is connected to the air hole 22.

[0033] like Figure 3 As shown, the measuring chassis 3 includes an upper measuring chassis 31 and a lower measuring chassis 32. The upper measuring chassis 31 is above the air flotation platform 2, and the lower measuring chassis 32 is below the air flotation platform 2. The upper measuring chassis 31 is equipped with a first light emitting mechanism 5 and an integrating sphere 6, and the lower measuring chassis 32 is equipped with a second light emitting mechanism 7 and a spectrometer 8. The light emitted by the first light emitting mechanism 5 and the second light emitting mechanism 7 enters the integrating sphere 6, and the integrating sphere 6 is connected to the spectrometer 8 through an optical fiber.

[0034] The first light-emitting mechanism 5 is located on the side of the integrating sphere 6, and the second light-emitting mechanism 7 is located below the integrating sphere 6. Each side and bottom of the integrating sphere 6 has a light inlet 61. The light emitted by the first and second light-emitting mechanisms 5 enters the integrating sphere 6 through the light inlet 61. Each top and side of the integrating sphere 6 has a fiber optic probe 62, which is connected to the spectrometer 8 via optical fiber. The integrating sphere 6 is used to homogenize the light from the light source and the sample, and transmits the light signal to the spectrometer 8 through the fiber optic probes 62 and the optical fiber. The light emitted by the first light-emitting mechanism 5 passes through the sample under test from the side and enters the integrating sphere 6, while the light emitted by the second light-emitting mechanism 7 passes through the sample under test and enters the integrating sphere 6, detecting the reflected and transmitted light from the sample. The light entering the integrating sphere 6 is transmitted to the spectrometer 8 through the fiber optic probe 62.

[0035] like Figure 4-5As shown, the first light-emitting mechanism 5 includes a first light source 51, a first motor 52, and a first baffle 53. The first light source 51 is opposite to the integrating sphere 6. The first motor 52 is located on one side of the first light source 51, and the first baffle 53 is mounted on the first motor 52, positioned between the first light source 51 and the integrating sphere 6. A first fan 54 is located on one side of the first light source 51. The first motor 52 drives the first baffle 53 to move, thereby controlling the opening and closing of the first baffle 53 and controlling the light from the first light source 51 entering the integrating sphere 6. In this embodiment, the first light source 51 is a bulb used for optical detection, powered by a high-precision power supply. The first fan 54 provides forced cooling to the first light source 51, ensuring the light source quality of the first light source 51.

[0036] like Figure 6-7 As shown, the second light-emitting mechanism 7 includes a second light source 71, a second motor 72, and a second baffle 73. The second light source 71 is opposite to the integrating sphere 6. The second motor 72 is located on one side of the second light source 71, and the second baffle 73 is mounted on the second motor 72, positioned between the second light source 71 and the integrating sphere 6. A second fan 74 is located on one side of the second light source 71. The second motor 72 drives the second baffle 73 to rotate, thereby controlling the opening and closing of the second baffle 73 and controlling the light from the second light source 71 entering the integrating sphere 6. In this embodiment, the second light source 71 is a bulb used for optical detection, powered by a high-precision power supply. The second fan 74 provides forced cooling to the second light source 71, ensuring the light source quality of the second light source 71.

[0037] Working principle: The optical inspection equipment is preheated and calibrated after stabilization. Then, the product to be tested is placed at the measurement position via the air flotation platform 2. The first motor 52 and the second motor 72 are controlled to drive the first baffle 53 and the second baffle 73 to move, so that the optical light emitted by the first light source 51 and the second light source 71 alternately enters the integrating sphere 6. The light is received by the fiber optic probe 62 and transmitted to the spectrometer 8. The spectrometer 8 processes the light information and transmits it to the computer 4. The computer 4 processes the data from the spectrometer 8 to obtain parameters such as reflectance spectrum, visible light reflectance, photovoltaic reflectance, color parameters, transmission spectrum, visible light transmittance, photovoltaic transmittance, and film thickness, which are then stored and displayed in the computer 4.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
