Description

Technical Field

[0001] This utility model belongs to the technical field of automotive rearview mirror production equipment, specifically relating to an automatic oiling device for automotive rearview mirror actuators. Background Technology

[0002] The rearview mirror actuator is a component used to drive the adjustment of the rearview mirror, typically employing a micro-motor or servo motor to achieve automatic adjustment. By receiving control commands, it drives the rearview mirror lens to adjust its angle, enabling normal driving visibility and blind spot compensation during turns. Since the actuator contains a motor and gear set, these mechanical structures inevitably experience friction during operation. Without lubrication, wear will be rapid, leading to shortened lifespan or increased noise. Therefore, the core purpose of lubrication is to lubricate and reduce friction and wear. Current lubrication operations are generally performed manually. Manual lubrication has the following problems: firstly, it is inefficient; the high speed of assembly line production makes manual lubrication unable to keep up, easily leading to production stockpiles; secondly, it is difficult to ensure consistent lubrication volume. Hand tremors during lubrication can result in some actuators having too much or too little lubrication, uneven lubrication affecting product performance and even causing leaks that contaminate other components. Therefore, the existing lubrication method needs to be improved to adapt to the rhythm of assembly line production and ensure the uniformity of lubrication operations. Utility Model Content

[0003] To address the aforementioned problems and technical needs, this utility model provides an automatic oiling device for automotive rearview mirror actuators. This device can automatically and quantitatively inject oil into automotive rearview mirror actuators and automatically detect them. It not only has high oiling efficiency but also ensures the uniformity of oil injection, making it more suitable for the production rhythm of automated production lines.

[0004] The technical solution of this utility model is as follows: An automatic oiling device for an automotive rearview mirror actuator includes a machine base, a belt conveyor, a tray, a lifting cylinder, a quantitative oiling mechanism, and a detection component. The machine base has a belt conveyor that carries the tray forward, on which workpieces are placed. Oiling stations and detection stations are sequentially arranged along the conveyor's direction. The machine base has lifting holes corresponding to the oiling and detection stations, and each lifting hole contains a lifting cylinder. When the tray is conveyed to the oiling or detection station, it stops, and the lifting cylinder passes through the lifting hole to lift the tray upwards. The machine base also has a quantitative oiling mechanism and a detection component. The quantitative oiling mechanism is located on both sides of the oiling station and automatically oils the workpieces lifted at the oiling station. The detection component is located on the side of the detection station and automatically detects the oiled workpieces. In this solution, a lifting cylinder is installed to push the pallet and workpiece upwards together at the oiling and testing stations. This provides good support for the pallet, facilitating the alignment and operation of the oiling process. During testing, lifting the pallet for imaging also avoids interference and improves the accuracy of the testing.

[0005] Furthermore, the quantitative oil injection mechanism includes an oil injection drive cylinder, a quantitative oil injection valve, a pressure reducing valve, and an oil injection head. Multiple columns are installed on both sides of the belt conveyor, vertically mounted on the machine platform. Fixed plates are installed inside the columns, with both fixed plates parallel to the conveying direction. An oil injection drive cylinder is mounted on the fixed plate, connected to a horizontal plate. The front end of the horizontal plate extends above the tray, and multiple oil injection heads are located at the end of the horizontal plate. The oil injection drive cylinder drives the oil injection heads to move vertically. A pressure reducing valve and a quantitative oil injection valve are also connected to the fixed plate, connected via pipelines. The quantitative oil injection valve and the oil injection head are also connected via pipelines. An external oil pump supplies oil to the pressure reducing valve, and the oil is pumped through the pressure reducing valve to the quantitative oil injection valve. The quantitative oil injection valve applies oil to the workpiece at the oil injection station through the oil injection head.

[0006] Furthermore, the quantitative oil injection mechanism is equipped with a pressure reducing valve, which is connected to an external oil pump. One or more quantitative oil injection valves are respectively provided on the fixed upright plates on both sides. The capacities of different quantitative oil injection valves are not the same. The pressure reducing valve is connected to multiple quantitative oil injection valves at the same time to deliver oil to the quantitative oil injection valves.

[0007] Furthermore, one or more oil injection drive cylinders are respectively provided on the fixed upright plates on both sides. Each oil injection drive cylinder has an oil injection head connected to a quantitative oil injection valve. For different parts of the same workpiece, different oil injection heads are used to apply oil.

[0008] The pressure reducing valve is connected to an external oil pump and can control the oil pressure, ensuring that the oil pressure input to each metering oil injection valve is consistent and the oil injection speed of each oil injection head is consistent. This prevents oil leakage caused by excessively fast injection speed or excessively slow injection speed, thus improving the stability and consistency of oil injection.

[0009] Furthermore, two pallet position sensors are fixedly installed on the side of the belt conveyor. The two pallet position sensors are respectively aligned with the oiling station and the inspection station, and the pallet position sensors can monitor the position of the pallets in real time.

[0010] Furthermore, a set of workpiece positioning sensors are respectively installed on both sides of the oiling station and the inspection station. The workpiece positioning sensors can sense the position of the workpiece on the tray.

[0011] Furthermore, the detection component includes a CCD camera and a tray RFID reader / writer. The CCD camera is mounted directly above the detection station via a bracket, and the tray RFID reader / writer is fixedly connected to the outside of the belt conveyor. The tray RFID reader / writer can read the information of the tray, and the CCD camera takes pictures of the workpieces at the detection station for inspection.

[0012] Furthermore, a protective cover is installed on the machine platform, which covers the components on the machine platform. Conveyor ports are provided on both sides of the protective cover, and a belt conveyor line is set through the two conveyor ports.

[0013] The beneficial effects of this utility model are as follows: This device can automatically inject oil into the workpiece and automatically detect the oil level. The belt conveyor on the machine can automatically transport the pallet and workpiece forward. The lifting cylinder pushes the pallet upward, which facilitates the automatic oil injection operation of the quantitative oil injection mechanism. The detection component can also take pictures to inspect the workpiece. Since the workpiece may need to be oiled in more than one place, and the amount of oil required for each oiling position is different, multiple independent oil injection drive cylinders and quantitative oil injection valves are set up to facilitate oil injection operations at different positions of the workpiece. The amount of oil can also be controlled individually, making the oil injection process more precise, ensuring the uniformity of oil injection, and having high oil injection efficiency. It can adapt to the production rhythm of the automatic line and ensure the performance of the product. Attached Figure Description

When the pallet 3 is conveyed to the oiling station 11 or the inspection station 12, it stops, and the lifting cylinder 4 can pass through the lifting hole 13 to lift the pallet 3 upward. The machine platform 1 is also equipped with a quantitative oiling mechanism 5 and a detection component 8. The quantitative oiling mechanism 5 is located on both sides of the oiling station 11 and automatically oils the workpiece that is lifted on the oiling station 11. The detection component 8 is located on the side of the inspection station 12 and automatically detects the workpiece that has been oiled.

[0024] The quantitative oil injection mechanism 5 includes an oil injection drive cylinder 53, a quantitative oil injection valve 54, a pressure reducing valve 55, and an oil injection head 56. Multiple columns 51 are provided on both sides of the belt conveyor 2. The columns 51 are vertically installed on the machine platform. Fixed plates 52 are provided inside the columns 51. The fixed plates 52 on both sides are parallel to the conveying direction. An oil injection drive cylinder 53 is installed on the fixed plate 52. A horizontal cross plate 531 is connected to the oil injection drive cylinder 53. The front end of the horizontal cross plate 531 extends above the tray 3. Multiple oil injection heads 56 are provided at the end of plate 531. Oil injection drive cylinder 53 drives the oil injection heads 56 to move vertically. A pressure reducing valve 55 and a metering oil injection valve 54 are also connected on the fixed upright plate 52. The pressure reducing valve 55 and the metering oil injection valve 54 are connected by pipelines. The metering oil injection valve 54 and the oil injection head 56 are also connected by pipelines. An external oil pump supplies oil to the pressure reducing valve. The oil is pumped from the pressure reducing valve 55 to the metering oil injection valve 54. The metering oil injection valve 54 applies oil to the workpiece at the oil injection station 11 through the oil injection head 56.

[0025] The metering oil injection mechanism 5 includes a pressure reducing valve 55 connected to an external oil pump. One or more metering oil injection valves 54 are respectively installed on the fixed upright plates 52 on both sides. The capacities of the different metering oil injection valves 54 are different. The pressure reducing valve 55 is connected to multiple metering oil injection valves 54 simultaneously, supplying oil to them. One or more oil injection drive cylinders 53 are respectively installed on the fixed upright plates 52 on both sides. Each oil injection drive cylinder 53 has an oil injection head connected to a metering oil injection valve 54. Different oil injection heads 56 are used to apply oil to different parts of the same workpiece.

[0026] The detection component 8 includes a CCD camera 81 and a tray RFID reader / writer 82. The CCD camera 81 is mounted directly above the detection station 12 via a bracket. The tray RFID reader / writer 82 is fixedly connected to the outside of the belt conveyor 2. The tray RFID reader / writer 82 can read the information of the tray, and the CCD camera 81 takes pictures of the workpieces on the detection station 12 for inspection.

[0027] Two pallet position sensors 6 are fixedly installed on the side of the belt conveyor line 2. The two pallet position sensors 6 are respectively aligned with the oiling station 11 and the inspection station 12. The pallet position sensors 6 can monitor the position status of the pallets 3 in real time. A set of workpiece position sensors 7 are also installed on both sides of the oiling station 11 and the inspection station 12. The workpiece position sensors 7 can sense the position status of the workpieces on the pallets.

[0028] The working process of this utility model is as follows: The belt conveyor 2 sends the pallet to the oiling station 11. The workpiece 31 is fixedly placed on the pallet 3. When the pallet positioning sensor 6 on the side of the oiling station 11 senses that the pallet is in position, the lifting cylinder 4 lifts the pallet 3 to position it. After the workpiece positioning sensors 7 on both sides of the oiling station 11 sense that the workpiece is in position, the oiling drive cylinder 53 drives the horizontal plate 531 to descend to position. The external oil pump pumps the oil to the pressure reducing valve 55, and then delivers it to each quantitative oiling valve 54 through the pressure reducing valve 55. The quantitative oiling valve 54 injects oil into each part of the workpiece through the corresponding oiling head 56. After the oiling is completed, the oiling drive cylinder 53 drives the horizontal plate 531 to return to its original position. Lifting cylinder 4 retracts, and pallet 3 is placed back on belt conveyor 2. Belt conveyor 2 transports pallet 3 to inspection station 12. After pallet positioning sensor 6 on the side of inspection station 12 senses that pallet 3 is in place, lifting cylinder 4 below inspection station 12 lifts pallet 3 again to position it. After workpiece positioning sensor 7 around inspection station 12 senses that workpiece 31 is in place, each pallet has a sensor plate. The pallet RFID reader 82 reads the information of the pallet to determine the type of workpiece. CCD camera 81 takes a picture of workpiece 31 to detect the oiling status of workpiece 31. After the detection is completed, lifting cylinder 4 retracts, and pallet 3 returns to belt conveyor 2 to continue to be transported.
