Description

Technical Field

[0001] This invention relates to the field of bearing oiling technology, and in particular to a bearing oiling control device and control method. Background Technology

[0002] After the bearing is assembled, oil needs to be sprayed between the inner and outer rings for lubrication. This is a key step to ensure the bearing operates normally and extends its service life.

[0003] In the prior art, patent document CN115228693B discloses a bearing oil control mechanism, method, and bearing oiling device, relating to the field of bearing processing technology. It includes a housing and a clamping disc. A drive shaft is arranged between the oil guide disc and the clamping disc, causing the drive shaft to drive a cam cylinder in the clamping disc to push the clamping member against the inner ring of the bearing, while simultaneously rotating the oil guide wheel in the oil guide disc. In this way, while the clamping member is clamping the inner ring of the bearing, the oil guide disc can simultaneously perform an oil release operation based on the movement of the clamping member, completing the oil spraying lubrication of the bearing. This provides consistency and reduces the use of sensing and control elements in existing solutions. Furthermore, when the bearing size changes, the extension length of the clamping member and the rotation angle of the oil guide wheel also change accordingly, and the amount of lubricating oil released also changes with the rotation angle of the oil guide wheel, achieving automatic adjustment of the oil spraying amount according to the bearing size.

[0004] Existing oiling methods lack immediate and effective quality inspection mechanisms after oiling, often resulting in defective products flowing into the next process and causing subsequent failures. Therefore, it is necessary to improve this structure to overcome the aforementioned shortcomings. Summary of the Invention

The field scan camera is used to acquire images of the bearing. There are two light sources, which are symmetrically distributed on the detection bracket.

Detailed Implementation

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to the figures and specific embodiments.

[0040] like Figures 1 to 5 As shown, the present invention proposes a bearing oiling control device, which includes a conveying unit for providing a moving path and driving the bearing to move along its length.

[0041] An oiling unit is installed on the conveying unit, with the oiling end of the oiling unit facing the conveying unit. It is used to apply oil to the bearings on the conveying unit.

[0042] The oil injection unit is located above the oiling unit, with the oil injection end of the oil injection unit facing the oiling unit. It is used to inject oil into the oiling unit.

[0043] The detection unit is located at the output end of the conveying unit, with the detection end of the detection unit facing the conveying unit. It is used to detect the surface of the bearing after it has been coated with oil.

[0044] The detection unit includes a detection bracket 1, on which a field array camera 2 is mounted. The image acquisition end of the field array camera 2 is vertically oriented towards the conveying unit. The field array camera 2 is used to acquire images of the bearing. There are two light sources 3, which are symmetrically arranged on the detection bracket 1. The illumination end of the light sources 3 is oriented towards the conveying unit. The light sources 3 and the detection bracket 1 are rotatably connected by a rotating shaft 4.

[0045] The area scan camera 2 is a high-resolution industrial digital camera, connected to an external image processing unit for analysis and processing. The light source 3 consists of two symmetrically arranged strip LED light sources. Each light source 3 can be adjusted at multiple angles around the rotation axis 4 and the vertical axis to ensure that the illumination direction covers the outer ring and end face of the bearing. The symmetrical arrangement of the light sources 3 reduces shadows and improves image contrast, which is beneficial for identifying the oil film distribution. When the bearing moves to the detection unit's station with the conveyor unit, the area scan camera 2 acquires images of the bearing surface and uploads them to the image processing system. Using a preset oil coverage model and grayscale analysis algorithm, the system determines whether the oil film is uniform and whether there are any missed areas or accumulations.

[0046] Specifically, the conveying unit includes a support section for providing support and installation space, a conveying bracket 5 mounted on the support section, and multiple conveying rollers mounted on the conveying bracket 5. These multiple conveying rollers are arranged along the length of the conveying bracket 5 and are linked together by a conveyor belt 6. It also includes two photoelectric sensors 7 located at both ends of the oiling unit. These photoelectric sensors 7 are used to detect whether the bearing has moved to the oiling unit's working position.

[0047] Specifically, the oiling unit includes an oil storage component and an oil dispensing component. The oil storage component includes an oil storage bracket 8, which provides support and installation space; and an oil storage member 9, which is disposed on the oil storage bracket 8. The oil storage member 9 has a fixing groove that extends through the oil storage member 9. An oil storage block 10 is disposed in the fixing groove, which is used to absorb oil. Preferably, the oil storage block 10 is a component made of sponge.

[0048] The oil outlet assembly includes a mounting plate 11, which is mounted on the oil storage bracket 8; two guide rails 12, symmetrically arranged on the mounting plate 11; a sliding block, which slides along the guide rails 12; a drive cylinder 13, mounted on the mounting plate 11, with its piston rod connected to the sliding block, and used to drive the sliding block to move along the guide rails 12; and two connecting rods 14. One end of the connecting rod 14 is connected to the sliding block and can move synchronously with the sliding block. The other end of the connecting rod 14 is connected to the oil outlet plate 15. The oil outlet plate 15 is provided with a pressing block 16. The pressing block 16 can move synchronously with the oil outlet plate 15. The pressing block 16 is located directly above the oil storage block 10. When in use, the driving cylinder 13 drives the sliding block and drives the connecting rod 14, the oil outlet plate 15, and the pressing block 16 to move, and presses the oil storage block 10, so that the oil in the oil storage block 10 flows to the bearing of the conveying unit.

[0049] The oil injection unit includes an oil injection bracket 17, which provides support and installation space. The bracket has multiple mounting holes, each housing an oil injection pipe 18. One end of the pipe 18 is connected to an external oil source (not shown in the figure), and the other end has an oil injection nozzle 19. An oil injection hole 20 is provided on the extrusion block 16, penetrating through it. An oil storage hole 21 is provided on the oil storage block 10. An oil sensor 22 is mounted on the bracket 17 and moves synchronously with it. The sensor passes through a detection hole on the extrusion block 16 to detect the oil content in the storage block 10. The bracket 17 is connected to an external servo mechanism (not shown in the figure), which drives its movement. In use, oil enters the storage hole 21 from the injection nozzle 19 through the injection hole 20.

[0050] The operating principle of this invention is as follows: The bearing is carried by a conveying unit and moves along a conveyor belt. Photoelectric sensors at both ends of the conveying unit detect the bearing position. When the bearing enters the oiling station, the conveying unit pauses and triggers the oiling action. Based on feedback from the oil sensor, the oiling unit injects a quantitative amount of oil into the oil storage hole of the oil storage block through the oiling nozzle. The driving cylinder of the oiling unit pushes the sliding block, connecting rod, and oil outlet plate downwards, and the extrusion block extrudes the oil storage block, causing the oil to seep out evenly and coat the bearing surface. After oiling, the bearing continues to move to the inspection station, where two adjustable-angle strip LED light sources provide symmetrical illumination to reduce shadows. A planar array camera vertically acquires images of the bearing surface and transmits the images to an external image processing unit. Through an oil film coverage model, the uniformity of the oil film and whether there is any missed coating or accumulation are judged. The inspection results are fed back to an external control unit (e.g., PLC). If the oil film is unqualified, the oil injection amount, extrusion pressure, or conveying speed can be adjusted; if qualified, the bearing continues to the next process.

[0051] A control method for a bearing oiling control device includes the following steps:

[0052] S1: Control the oil injection unit to inject oil into the oil storage block of the oiling unit. The real-time humidity value is obtained through the oil sensor integrated on the oil injection bracket. Closed-loop control (such as PID control) is used to compare the real-time humidity value with the target humidity range. When the real-time humidity value is lower than the lower limit of the target humidity range, oil injection begins; when the real-time humidity value reaches the upper limit of the target humidity range, oil injection stops.

[0053] This step ensures that the oil storage block is always kept in an optimal and uniform oil content, avoiding dripping due to oversaturation or uneven oiling due to insufficient oiling.

[0054] S2: Start the conveyor unit to sequentially transport the bearings to the oiling station. Photoelectric sensors installed along the conveyor path precisely detect whether the bearings have reached the predetermined position directly below the extrusion block. This signal serves as the precise start command to trigger the oiling action.

[0055] S3: After receiving the bearing positioning signal, control the drive cylinder of the oiling unit to push the sliding block, connecting rod and oil outlet plate, so that the extrusion block is pressed down according to the preset stroke and speed; the extrusion block performs quantitative extrusion on the oil storage block in the optimal humidity, and squeezes out the oil evenly and directly coats it onto the outer ring surface of the bearing directly below it. After extrusion is in place, maintain a short pressure holding process to ensure that the oil is fully transferred, and then drive the cylinder to drive the extrusion block to reset.

[0056] S4: The image of the bearing is acquired by the detection unit, and the oil film status of the oiled bearing is detected by the preset oil coating coverage model. If the oil quantity is not up to standard, the output oil quantity of the oil injection unit is adjusted.

[0057] Example 1:

[0058] Step S1: The oil injection unit starts, and the external servo module drives the oil injection bracket to move, aligning the oil sensor probe with the oil storage block for detection. The PLC reads the real-time humidity value returned by the oil sensor and compares it with the preset target humidity range (e.g., corresponding to the saturation of the oil storage block at 70%-80%). If the real-time humidity value is below 70%, the PLC starts the metering oil pump to ensure uniform oil wetting; when the detected humidity value reaches 80%, oil injection stops immediately. This closed-loop control ensures that the oil storage block is in an optimal and stable oil-containing state before each oiling action, laying the foundation for metered oil dispensing.

[0059] Step S2: Place the bearings at a certain interval at the inlet end of the conveyor belt. The conveyor belt runs continuously, and the bearings are transported to the oiling station. When the bearing blocks the first photoelectric sensor, the signal is recorded. When the bearing fully reaches and blocks the second photoelectric sensor, the PLC immediately sends an emergency stop signal to the conveyor belt driver, causing the bearing to stop precisely below the oil storage block. The arrival signal simultaneously triggers the oiling action sequence.

[0060] Step S3: Upon receiving the arrival signal, the PLC controls the drive cylinder of the oiling unit to drive the piston rod downwards at a constant speed. The piston rod, through the sliding block and connecting rod, moves the oil outlet plate and the extrusion block downwards together. The extrusion block smoothly contacts and presses into the oil storage block to a preset depth. After reaching the preset pressing position, it maintains this state for 0.5 seconds, allowing the oil in the oil storage block to fully and evenly seep out to its bottom surface under pressure and transfer to the stationary outer ring surface of the bearing. After the pressure holding period ends, the drive cylinder drives the extrusion block to quickly reset and rise, detaching it from the oil storage block. The conveyor belt receives the PLC command and restarts, sending the oiled bearing to the inspection station, while simultaneously conveying the next bearing to be oiled to the oiling station.

[0061] Step S4: Two strip LED light sources illuminate at a preset angle, providing uniform illumination to the bearing surface. An area-array industrial camera is triggered, capturing a high-resolution image of the bearing surface. The image is transmitted to the image processing unit in real time. The industrial control computer software performs the following analyses: Preprocessing: Image noise reduction and contrast enhancement. Region segmentation: Identifying key areas such as the bearing outer ring and end face.

[0062] Grayscale analysis: Calculate the mean and standard deviation of grayscale values ​​for each region. Since there is a significant difference in grayscale values ​​between oil film and non-oil film areas, a pre-established "oil coverage model" (based on a grayscale distribution threshold trained from a large number of qualified samples) is used to determine whether the oil film coverage is complete. By analyzing the uniformity of the grayscale distribution, defects such as missed coating or oil accumulation are detected. If the analysis result is deemed "qualified," the PLC controls the conveyor belt to send the bearing into the qualified product outflow channel. If it is determined to be "too thin an oil film" or "missed coating," a "insufficient oil injection" signal is sent to the PLC. Based on this, in the next oil injection cycle (step S1), the PLC slightly increases the upper limit of the target humidity range (e.g., from 80% to 82%), or increases the single oil injection pulse time of the metering oil pump to increase the oil injection volume. If it is determined to be "too thick an oil film" or "accumulated," a "too much oil injection" signal is sent, and the PLC accordingly slightly decreases the target humidity range or reduces the oil injection volume.

[0063] In summary, step S1 ensures that each bearing receives a quantitative and uniform oil film, greatly improving product consistency. The linkage between steps S2 and S3 enables a continuous cycle of automatic bearing positioning, triggering, oiling, and resetting, reducing manual intervention and improving production reliability. The closed-loop oiling and quantitative extrusion mechanism based on humidity sensing fundamentally avoids oil waste or overuse, achieving lean production. The image detection and feedback mechanism in step S4 enables the system not only to judge the oiling quality but also to adaptively adjust the oiling parameters, forming a continuously optimized intelligent control closed loop.
