Description

Technical Field

[0001] This utility model relates to the technical field of headrest rod oiling equipment, specifically to an oiling device for automobile seat headrests. Background Technology

[0002] The lubrication process for automotive seat headrests is crucial for ensuring smooth sliding between the headrest rod and the seat frame. Traditional lubrication equipment relies heavily on manual operation, resulting in low lubrication efficiency, inconsistent oil volume control, and significant oil residue. Furthermore, existing equipment is typically designed for a single headrest specification, making it difficult to adapt to the dimensional differences in headrest rods across different vehicle models, leading to insufficient production flexibility. Additionally, manual operation is prone to introducing errors, affecting product consistency, and the open lubrication environment can cause lubricant splattering, contaminating the working environment.

[0034] Combination Figures 1-8 An oiling device for automotive seat headrests includes an equipment box 1, a control box 2, and an oiling box 3. The control box 2 and the oiling box 3 are fixedly arranged side by side on the top of the equipment box 1, and the bottom surface of the equipment box 1 is provided with casters 4 for supporting movement. This makes the device compact in structure, easy to operate and maintain. The casters 4 have both support and movement functions. When the device needs to be fixed in one position, it can provide stable support, and when the device needs to be adjusted, it can be moved easily to adapt to different production scenarios and workstation layout requirements.

[0035] The equipment housing 1 contains a lubricating oil tank 24, an oil pump 9 connected to the lubricating oil tank 24 via a pipeline, and a metering pump 10 connected to the oil pump 9 via a pipeline. The lubricating oil tank 24 serves as a container for storing lubricating oil, providing a source of lubricating oil for the entire oiling process. The oil pump 9 is connected to the lubricating oil tank 24 via a pipeline, and its function is to draw lubricating oil from the lubricating oil tank 24 and deliver it to the metering pump 10. The metering pump 10 is connected to the oil pump 9 via a pipeline, and it can precisely control the amount of lubricating oil delivered to the oiling mechanism, ensuring that the amount of oil applied each time is stable and meets the process requirements, avoiding the impact on oiling quality due to excessive or insufficient oil.

[0036] The control box 2 is equipped with a PLC controller 5, which is electrically connected to the oil pump 9 and the fixed displacement pump 10. The control box 2 is also equipped with a servo motor 11 electrically connected to the PLC controller 5. The PLC controller 5 is the control core of the entire equipment. It is electrically connected to the oil pump 9 and the fixed displacement pump 10. Through a pre-written program, it can precisely control the working status of the oil pump 9 and the fixed displacement pump 10, such as controlling the start and stop of the oil pump 9 and the flow rate, and the output oil volume of the fixed displacement pump 10. It can also precisely control the rotation direction, speed and angle of the servo motor 11 according to the actual oiling requirements, thereby achieving precise adjustment of the oiling position.

[0037] The oiling tank 3 is equipped with an openable cover 6. The cover 6 is rotatably mounted on the oiling tank 3 and can be sealed with the oiling tank 3, which facilitates the maintenance and cleaning of the inside of the oiling tank 3. The cover 6 is equipped with a headrest rod insertion seat 19, a space-avoiding box 7 for placing the headrest, and a working status indicator light 8. The headrest rod insertion seat 19 is used to fix the headrest rod. The space-avoiding box 7 provides a space for placing the headrest to avoid damage to the headrest during the oiling process. The working status indicator light 8 can intuitively display the working status of the equipment, such as running, paused, fault, etc., so that the operator can understand the status of the equipment in a timely manner.

[0038] The oiling tank 3 is equipped with a position adjustment mechanism that is driven by the servo motor 11. The position adjustment mechanism is equipped with an oiling mechanism. The position adjustment mechanism includes a mounting plate 12 fixedly installed on the bottom surface of the oiling tank 3. On the mounting plate 12, there are connecting blocks 14 opposite each other on both sides. The two connecting blocks 14 are rotatably connected to the servo motor 11 via bearing seats. There are two guide rods 16 symmetrically arranged between the two connecting blocks 14 and on both sides of the screw 13. The screw 13 is threadedly connected to an adjustment block 17 that slides with the two guide rods 16. When the servo motor 11 rotates, it drives the screw 13 to rotate through the coupling. The adjustment block 17 threadedly connected to the screw 13 will slide linearly along the two guide rods 16 under the action of the rotation of the screw 13, thereby realizing the position adjustment.

[0039] The oiling mechanism includes two pairs of oil spraying components. One pair of oil spraying components is symmetrically arranged on both sides of one of the connecting blocks 14, and the center of this pair of oil spraying components is located directly below one of the fixed insertion holes 20. The other pair of oil spraying components is symmetrically arranged on both sides of the adjusting block 17. As the adjusting block 17 moves, it can be adjusted to the two sides directly below the other fixed insertion hole 20 and the movable insertion hole 23. The oil spraying components include a mounting bracket 15 and an atomizing nozzle 18 arranged on the mounting bracket 15. The atomizing nozzle 18 is connected to the output end of the metering pump 10 through a pipeline. The metering pump 10 delivers lubricating oil to the atomizing nozzle 18. The atomizing nozzle 18 atomizes the lubricating oil and sprays it evenly on the surface of the headrest bar to realize the oiling operation.

[0040] The oiling tank 3 is also equipped with a negative pressure pump 26 connected to the lubricating oil tank 24 via a pipeline. A filter element 27 is also installed on the connecting pipeline between the negative pressure pump 26 and the lubricating oil tank 24. The negative pressure pump 26 is electrically connected to the PLC controller 5. After the oiling is completed, the negative pressure pump 26 generates negative pressure to draw back the excess lubricating oil in the oiling tank 3 and transport it to the lubricating oil tank 24 through the connecting pipeline. The filter element 27 can filter out impurities and contaminants in the lubricating oil, ensuring the quality of the recovered lubricating oil, realizing the recycling of lubricating oil, reducing resource waste, and preventing the lubricating oil from polluting the working environment.

[0041] The headrest rod connector 19 has two fixed insertion holes 20 and an adjustable movable mechanism between them. The movable mechanism has a movable insertion hole 23. The headrest rod connector 19 also has several sensors 25 for detecting the position of the headrest rod. These sensors 25 can be proximity sensors, etc. Each sensor 25 is electrically connected to a PLC controller 5. The headrest rod connector 19 has a movable cavity 21 and a through slot communicating with the movable cavity 21. The movable mechanism includes a movable block 22 slidably disposed in the movable cavity 21. The movable insertion hole 23 is disposed on the movable block 22, and one of the sensors 25 is correspondingly disposed on it. At one of the fixed insertion holes 20, the other sensors 25 are correspondingly set at the moving cavity 21. The operator can manually adjust the position of the moving block 22 in the moving cavity 21 according to the different spacing requirements of the headrest rods, thereby adjusting the position of the moving insertion hole 23 to meet the oiling requirements of different specifications of headrest rods. When a headrest rod is inserted into the fixed insertion hole 20 or the moving insertion hole 23, the sensor 25 can detect the position information of the headrest rod in time and feed the information back to the PLC controller 5. The PLC controller 5 accurately controls the operation of the position adjustment mechanism and the oiling mechanism according to the information fed back by the sensor 25 to ensure that the oiling position is accurate.
