Description

Technical Field

[0001] This utility model relates to the field of engine oil testing technology, specifically to a spectroscope module for engine oil testing. Background Technology

[0002] Engine oil, as a lubricant for engines, has six core functions: lubrication and friction reduction, cooling, cleaning, sealing and leak prevention, rust and corrosion prevention, and shock absorption. Furthermore, it absorbs heat and removes impurities through its circulating flow, ensuring efficient and stable engine operation. This is crucial for reducing wear on engine parts and extending their service life. Regular oil checks can help identify potential problems early, reduce the risk of equipment failure, and save on maintenance costs.

[0003] Current methods for testing engine oil typically involve filtration to measure viscosity and impurities. This approach is cumbersome, inefficient, and fails to provide a clear visual representation of the results. Therefore, it does not meet current requirements. To address this, we propose a spectroscope module for engine oil testing. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model uses a light source to emit a mixed light composed of infrared and visible light to irradiate flowing engine oil. The irradiated mixed light enters the inner side of the lens barrel through the light inlet and passes through the first, second, third, fourth, fifth, and sixth lenses in the lens assembly in sequence to adjust the optical path. Then, the infrared light in the mixed light is reflected and the visible light is transmitted through the beam splitter, realizing the effective separation of infrared and visible light. This allows the first and second light-catching chips to receive the infrared and visible light respectively and convert them into image information. Based on the image information, the quality of the engine oil can be quickly and intuitively determined.

[0012] 2. This utility model allows for easy adjustment of the distance between the lens assembly and the beam splitter by rotating the lens barrel relative to the mounting sleeve. At the same time, the protective box facilitates effective shielding of the optical path to avoid the influence of external light. The positioning gear ring and the connecting gear plate are connected by interlocking teeth. The connecting column drives the connecting gear plate to adjust the installation angle relative to the positioning gear ring. This allows the two connecting columns to adjust the installation tilt angle of the beam splitter through the transmission frame, thus achieving efficient reflection of infrared light.

The beam splitter 3 is located between the first light-catching chip 4 and the second light-catching chip 5. The beam splitter 3 reflects infrared light in the mixed light and transmits visible light, thereby achieving effective separation of infrared light and visible light.

[0021] A lens barrel 2 is installed behind the beam splitter 3. A light inlet 201 is provided on the rear end face of the lens barrel 2. The first light-catching chip 4 and the second light-catching chip 5 are perpendicular to each other. A lens assembly 6 is installed on the inner side of the lens barrel 2. The light inlet 201, the lens assembly 6, and the second light-catching chip 5 are coaxial, which facilitates the reception and conversion of infrared light and visible light by the first light-catching chip 4 and the second light-catching chip 5 into image information. Based on the image information, the quality of the engine oil can be quickly and intuitively measured.

[0022] Please see Figure 2 and Figure 3 The lens assembly 6 includes a first lens 601. The front end face of the first lens 601 is sequentially equipped with a second lens 602, a first washer 603, a third lens 604, a fourth lens 605, a fifth lens 607, a third washer 608, a sixth lens 609, and a fourth washer 610. A second washer 606 is installed on the outer side of the fourth lens 605. The third lens 604 and the fifth lens 607 are connected through the second washer 606. The lens assembly 6 facilitates the adjustment of the optical path.

[0023] Please see Figure 4 and Figure 5 A protective mounting unit 7 is installed on the outside of the chip holder 1. The protective mounting unit 7 includes a protective box 701. A mounting sleeve 702 is fixedly installed in the middle of the rear end face of the protective box 701. Positioning grooves 704 are provided on both sides of the protective box 701. A locking knob 703 is installed on the upper end of the protective box 701. The lens barrel 2 is connected to the mounting sleeve 702 by threads. The bottom end of the locking knob 703 passes through the protective box 701 and is connected to the chip holder 1 by threads. The protective box 701 and the chip holder 1 are locked together by the locking knob 703. The distance between the lens assembly 6 and the beam splitter 3 can be adjusted by rotating the lens barrel 2 relative to the mounting sleeve 702. At the same time, the protective box 701 can effectively shield the light path and avoid the influence of external light.

[0024] Please see Figure 4 and Figure 5An angle adjustment unit 8 is installed in the middle of the protective installation unit 7. The angle adjustment unit 8 includes a transmission frame 804. Connecting posts 803 are installed at both ends of the transmission frame 804. A connecting gear plate 802 is fixedly installed on the outer side of one end of the connecting post 803. A positioning gear ring 801 is installed on the outer side of the connecting gear plate 802. The positioning gear ring 801 and the connecting gear plate 802 are located inside the positioning groove 704. The two positioning gear rings 801, the connecting gear plate 802, and the connecting posts 803 are symmetrically installed relative to the transmission frame 804. The protective box 701 and the two The positioning gear ring 801 is fixedly connected, and the connecting gear plate 802 is connected to the positioning gear ring 801 through inter-tooth meshing. The connecting post 803 passes through the connecting gear plate 802 and the protective box 701 and is slidably connected to the transmission frame 804. The beam splitter 3 is bonded and fixed to the transmission frame 804. The connecting post 803 is connected to the protective box 701 through threads. The connecting post 803 drives the connecting gear plate 802 to adjust the installation angle relative to the positioning gear ring 801, so that the two connecting posts 803 drive the beam splitter 3 to adjust the installation tilt angle through the transmission frame 804.

[0025] In summary, when performing light transmittance testing on engine oil, a light source is provided behind the lens barrel 2. The sample containing engine oil is placed between the light source and the lens barrel 2. When the power is turned on, the light source emits a mixed light composed of infrared and visible light to irradiate the flowing engine oil. The mixed light after irradiation enters the inner side of the lens barrel 2 through the light inlet 201, and then passes through the first lens 601, the second lens 602, the third lens 604, the fourth lens 605, the fifth lens 607 and the sixth lens 609 in the lens assembly 6 in sequence to adjust the optical path.

[0026] Then, the infrared light in the mixed light is reflected and the visible light is transmitted through the beam splitter 3, so as to effectively separate the infrared light and the visible light. This makes it easier for the first light-catching chip 4 and the second light-catching chip 5 to receive the infrared light and the visible light respectively and convert them into image information. Based on the image information, the quality of the engine oil, namely viscosity and impurity content, can be quickly and intuitively measured.

[0027] The rotation of the lens barrel 2 relative to the mounting sleeve 702 facilitates the adjustment of the distance between the lens assembly 6 and the beam splitter 3. At the same time, the protective box 701 effectively shields the optical path to avoid the influence of external light. The positioning gear ring 801 and the connecting gear plate 802 are connected by interlocking teeth. The connecting column 803 drives the connecting gear plate 802 to adjust the installation angle relative to the positioning gear ring 801. This allows the two connecting columns 803 to adjust the installation tilt angle of the beam splitter 3 through the transmission frame 804, thus achieving efficient reflection of infrared light.
