Description

Technical Field

[0001] This invention relates to the field of infrared light source detection, and in particular to a detection device based on a MEMS infrared light source. Background Technology

[0002] MEMS infrared light source oil detection devices play a key role in detecting iron filings in oil. During the operation of various mechanical equipment, friction between metal parts inevitably produces wear particles such as iron filings. After these iron filings are mixed into the oil, their composition, content, and size can directly reflect the wear condition of the equipment.

[0003] According to announcement number CN118275164B, the state of oil directly affects the reliability and lifespan of industrial equipment during operation, making real-time and accurate oil detection crucial. Oil detection devices based on MEMS infrared light sources have been widely used in recent years for oil contamination detection and component analysis due to their advantages of small size, low power consumption, and high integration. This device emits infrared light of a specific wavelength using a MEMS infrared light source, and utilizes the differences in the absorption and scattering characteristics of infrared light by different components in the oil to achieve quantitative analysis of parameters such as contaminant content and additive concentration in the oil.

[0004] However, in actual testing, this device faces a technical bottleneck due to the viscosity characteristics of the oil. The viscosity range of industrial oils (such as lubricating oil and hydraulic oil) is typically between 10 and 1000 cSt, and some high-viscosity oils used under special operating conditions can even reach several thousand cSt. When such high-viscosity oils are laid on the inner side of the testing tank, their flow rate is significantly reduced due to the combined effects of intermolecular cohesion and wall adhesion. For example, when testing 150 cSt lubricating oil used in gearboxes, the average flow rate of the oil in the testing tank is less than 0.1 mm / s, which is tens of times slower than low-viscosity liquids (such as water, whose flow rate can reach several mm / s).

[0005] The principle of infrared detection technology dictates that it has strict requirements regarding the spreading state of the oil. To ensure the accuracy and repeatability of the test results, the oil must be evenly spread within the detection area, forming a stable liquid layer of uniform thickness, so that infrared light can penetrate the oil in a predictable manner. However, high-viscosity oils have slow flow rates, and relying on their natural flow to complete the spreading process is extremely time-consuming. This not only severely reduces detection efficiency but also fails to meet the needs of rapid detection in industrial settings.

[0006] To address the aforementioned problems, a detection device based on a MEMS infrared light source is proposed. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1.

Compared with natural flow, the oil layer formation speed is increased, thereby improving the detection efficiency.

[0023] 3. The present invention provides a detection device based on a MEMS infrared light source, which generates a compound eddy current effect by the up-and-down movement of the wave trajectory of the second push plate in conjunction with the vibration of the first paddle, thereby increasing the bubble precipitation rate in the oil and prolonging the suspension time of iron filings, thus ensuring the stability of the infrared detection signal.

[0024] 4. The detection device based on a MEMS infrared light source provided by this invention uses a gradually varying amplitude design of the second guide groove to dynamically adjust the stroke of the second pusher plate according to the oil volume.

[0041] The swing mechanism 7 includes a sliding component 71 and a guide component 72, with the guide component 72 disposed on one side of the sliding component 71;

[0042] The pushing mechanism 6 includes a cylinder 601 fixedly connected to one side of the outer casing 1. A pneumatic rod 602 is fixedly connected to the output end of the cylinder 601. A first connecting plate 603 is fixedly connected to one end of the pneumatic rod 602. A second connecting plate 604, fixedly connected to the outer casing 1, is provided on the side of the first connecting plate 603 away from the detection pool 2.

The horizontal height of point a of the first guide groove 605 is higher than the horizontal height of point b of the first guide groove 605, so that when the first guide rod 607 moves to the position of point a of the first guide groove 605, it can move to the upper inner side of the first guide groove 605 when it moves back. Both the upper and lower ends of the first guide groove 605 are horizontal straight lines, and the appearance structure of the end of the first guide groove 605 near the cylinder 601 is a vertical straight line, so that the first guide rod 607 at the first... When the upper and lower ends of the guide groove 605 and the inner side of the end near the cylinder 601 move, there will be no shaking. The first connecting plate 603 is provided with a first guide hole 606 inside. The inner side of the first guide groove 605 is provided with a first guide rod 607 nested below the first guide hole 606 and vertically slidably connected to the first connecting plate 603. One end of the first guide rod 607 is fixedly connected to a first baffle 608. The detection pool 2 has a first hole 609 opened inside on the lower side near the air rod 602. The interior of the hole 609 is provided with a first connecting rod 610 fixedly connected to the first baffle 608.

The width of the first hole 609 is greater than the width of the first connecting rod 610, so that the first connecting rod 610 will not shake when it moves inside the first hole 609.

[0043] The sliding assembly 71 includes a second guide rod 7101 nested inside the first guide hole 606. A second guide groove 7102 is formed on the side of the second connecting plate 604 near the first connecting plate 603. The highest point of the wave-shaped upper end of the second guide groove 7102 gradually decreases from the first discharge pipe 4 towards the second discharge pipe 7109, and the lowest point of the wave-shaped upper end of the second guide groove 7102 is on the same horizontal line. The highest point of the wave-shaped upper end of the second guide groove 7102, located above the corresponding support plate 7110, is at the same horizontal height as the highest point of the wave-shaped upper end of the second guide groove 7102 near the support plate 7110. A second hole 7103 is formed inside the detection pool 2 on the side near the air rod 602. A part corresponding to the second guide rod 7101 is provided inside the second hole 7103. A second connecting rod 7104 is fixedly connected. A third connecting plate 7105 is provided below the second connecting rod 7104. A first sliding groove 7106 is opened inside the upper part of the third connecting plate 7105. A slider 7107 fixedly connected to the second connecting rod 7104 is provided inside the first sliding groove 7106. The lower end width of the slider 7107 is greater than the upper end width of the slider 7107. A second push plate 7108 is fixedly connected below the third connecting plate 7105. A second discharge pipe 7109 is connected to the lower part of the detection pool 2 near the cylinder 601. A bearing plate 7110 is fixedly connected to the inner part of the lower part of the detection pool 2 near the cylinder 601. The lower end of the second guide groove 7102 has a horizontal straight shape, and the two horizontal ends of the second guide groove 7102 have a vertical straight shape.

[0044] The first push plate 611 has a groove 8 on its upper surface near the cylinder 601. One end of the third connecting plate 7105 is nested inside the groove 8. A third guide groove 9 is formed on the inner wall of the groove 8. The third guide groove 9 has a vertical straight shape. The guide assembly 72 includes a third guide rod 7201 fixedly connected to the third guide groove 9. A fourth guide groove 7202 is provided on one side of the third guide groove 9. The fourth guide groove 7202 has an inclined straight shape, and multiple fourth guide grooves 7202 are arranged equidistantly along the vertical direction. The lower end of the lowest fourth guide groove 7202 is connected to a fifth guide groove that is connected to the third guide groove 9. The groove 7203, the second push plate 7108 is fixedly connected to the side of the first push plate 611 with a first paddle 7204, the first push plate 611 is fixedly connected to the side of the second push plate 7108 with a second paddle 7205, the third guide groove 9 and the fourth guide groove 7202 are connected to a second sliding groove 7208, the inner side of the second sliding groove 7208 is slidably connected to a second baffle 7206, the side of the second baffle 7206 is fixedly connected to an elastic rubber pad 7207 which is fixedly connected to the first push plate 611, the upper and lower surfaces of the second baffle 7206 are inclined surfaces, and the inclination direction of the upper and lower surfaces of the second baffle 7206 is consistent with the inclination direction of the third guide groove 9.

[0045] When oil needs to be tested, the oil is discharged from the feed pipe 3 into the space between the first push plate 611 inside the test tank 2. The cylinder 601 is activated, which drives the air rod 602 and the first connecting plate 603 to move towards the cylinder 601. This causes the first guide rod 607, located inside the first guide hole 606, to move at the upper end of the first guide groove 605. This causes the first baffle 608 and the first push plate 611 to move laterally. At this time, there is a certain gap between the first push plate 611 and the inner bottom surface of the test tank 2. The oil is pushed by the first push plate 611 and spread evenly on the inner bottom surface of the test tank 2, resulting in better testing results. Because the flow of the oil is forcibly pushed by the first push plate 611, the spreading speed is much greater than the natural flow of the oil, thereby improving the testing efficiency.

[0046] When the first push plate 611 moves laterally, it drives the elastic cleaning cloth 612 to move laterally, thereby cleaning the lower surface of the optical lens 5, resulting in higher detection accuracy.

[0047] When the first connecting plate 603 and the first guide hole 606 move laterally, they drive the second guide rod 7101 to move laterally. Because the upper end of the second guide groove 7102 has a wavy appearance, the second guide rod 7101 moves inside the upper end of the second guide groove 7102. This causes the second guide rod 7101 to drive the second connecting rod 7104 to move up and down, which in turn drives the slider 7107 and the third connecting plate 7105 to move up and down, which in turn drives the second push plate 7108 to move up and down. This causes the first paddle 7204 and the second paddle 7205 to collide with each other and generate vibration, which accelerates the discharge of air bubbles inside the oil. Since air bubbles refract infrared light, reducing air bubbles can improve the accuracy of detection.

[0048] When the oil is pushed by the first push plate 611, the first paddle 7204 and the second paddle 7205 vibrate. Because the oil is pushed by the first push plate 611, there is relative motion between the oils themselves. The vibration allows the air bubbles to be discharged more quickly.

[0049] Since the oil is mostly lubricating oil drawn from the inside of the gear pump, it contains a large amount of iron filings. When these iron filings quickly settle to the bottom of the oil, they can block infrared light from penetrating when they accumulate. When the second push plate 7108 moves up and down, it can drive the oil to move up and down, causing the iron filings inside the oil to move up and down. Under the action of inertia, the iron filings move upward inside the oil, reducing the phenomenon of iron filings settling to the bottom. Combined with the lateral movement of the first push plate 611, the iron filings can be evenly distributed inside the detection pool 2, reducing the accumulation of iron filings and thus reducing the situation where infrared light is blocked and the iron filings at the bottom cannot be reduced, thereby improving the detection accuracy.

[0050] The third connecting plate 7105 moves up and down, driving the third guide rod 7201 to move up and down as well. Because the fourth guide groove 7202 has an inclined straight-line structure and multiple fourth guide grooves 7202 are equidistantly arranged along the vertical direction, and the upper and lower surfaces of the second baffle 7206 are both inclined surfaces, with the inclination direction of the upper and lower surfaces of the second baffle 7206 consistent with the inclination direction of the third guide groove 9, when the third guide rod 7201 moves to the junction of the third guide groove 9 and the fourth guide groove 7202, it can move downwards along the corresponding height of the fourth guide groove 7202. The third connecting plate 7105 and the second push plate 7108 move towards the cylinder 601 to release material, and the third guide rod 7201 returns to the inner side of the fifth guide groove 7203, and then back to the inner side of the third guide groove 9, pushing the second baffle 7201. 06. The third guide rod 7201 is limited to move and reset, so that the third guide rod 7201 can continue to move upward along the trajectory of the third guide groove 9 for the next movement. Since the highest point of the wave shape at the upper end of the second guide groove 7102 gradually decreases from the first discharge pipe 4 to the second discharge pipe 7109, and the lowest point of the wave shape at the upper end of the second guide groove 7102 is on the same horizontal straight line, the rising distance of the second guide rod 7101 gradually decreases. When the first push plate 611 pushes the oil to move laterally towards the cylinder 601, the oil will continuously decrease, correspondingly reducing the rising distance of the second push plate 7108 and the first deflector 7204. This avoids the first deflector 7204 breaking through the upper surface of the oil, causing vibration when the upper surface of the oil breaks, resulting in air mixing into the oil and generating bubbles.

[0051] Because the highest point of the wave-shaped upper end of the second guide groove 7102 located above the support plate 7110 is at the same horizontal height as the highest point of the wave-shaped upper end of the second guide groove 7102 near the support plate 7110, when the second guide rod 7101 moves to the upper end of the second guide groove 7102 above the support plate 7110, the second guide rod 7101 moves up and down on a large scale. The second guide rod 7101 drives the first paddle 7204 to move up and down on a large scale, so that the oil adhering to the side of the first push plate 611 is vibrated and falls above the support plate 7110 and is discharged from the second discharge pipe 7109, reducing subsequent contamination.

[0052] When the first guide rod 607 moves to the end of the first guide groove 605 near the cylinder 601, the first guide rod 607 and the first push plate 611 descend under the action of gravity. After the test is completed, the cylinder 601 is activated to drive the air rod 602 and the first connecting plate 603 to reset, so that the first push plate 611 moves back and, under the action of gravity, the first push plate 611 contacts the inner upper surface of the test pool 2, pushing the tested oil to the first discharge pipe 4. At this time, the valve corresponding to the first discharge pipe 4 is opened so that the oil can be discharged, thus completing the test.
