Description

Technical Field

[0001] This disclosure relates to the technical field of automotive lens manufacturing, and in particular to an aluminum tube degreasing method based on a cold-drawing oil cleaning device and an automotive lens. Background Technology

[0002] With the continuous upgrading of the intelligence level of new energy vehicles, most new energy vehicles are now equipped with multiple sets of onboard cameras. These cameras can collect environmental information about the vehicle's surroundings in real time while the vehicle is in motion, effectively improving driving safety. To ensure both the structural strength and heat dissipation performance of the lens module, the lens module's housing is usually made of aluminum.

[0003] During the processing, aluminum tubes generally require the cold drawing process disclosed in Chinese patent document CN109127768A to ensure that the formed aluminum tubes meet the size and performance specifications of the lens module housing. Specifically, in order to reduce the frictional resistance between the aluminum tube and the cold drawing die during the cold drawing process, the workers will pre-coat the surface of the aluminum tube evenly with cold drawing oil before starting the cold drawing process, relying on the cold drawing oil to achieve lubrication and protection of the aluminum tube surface.

[0004] Currently, please refer to Figure 1 To facilitate the cold drawing process of aluminum tubes, most aluminum tubes need to be flattened at the starting end of the cold drawing process after being coated with cold drawing oil. This will hinder the flow of cold drawing oil into the aluminum tube during the coating process, making it easy for it to remain in the aluminum tube. The residual cold drawing oil is easy to burn during the cutting process of the aluminum tube, producing harmful fumes and thus polluting the environment. Summary of the Invention

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an aluminum tube degreasing method and vehicle lens based on a cold-drawn oil cleaning device that can remove cold-drawn oil from aluminum tubes more quickly and cleanly.

[0006] The purpose of this disclosure is achieved through the following technical solution: A method for degreasing aluminum tubes based on a cold-drawing oil cleaning device, wherein the cold-drawing oil cleaning device comprises: A right-angle bracket, comprising a horizontal base and a vertical support rod, wherein the vertical support rod is fixedly installed on the first side of the horizontal base and is arranged perpendicular to the horizontal base, and the vertical support rod is used to support the flat end of the aluminum tube; An oil recovery storage block, the oil recovery storage block having a placement slope, the oil recovery storage block being fixedly installed on the second side of the horizontal base, the placement slope being positioned opposite to the vertical support side rod; An adapter tray is installed on the inclined surface and is used to fit the round end of the aluminum tube; the adapter tray has an oil collection hole that is connected to the interior of the oil recovery storage block. The aluminum tube degreasing method based on the cold-drawn oil cleaning device includes the following steps: The aluminum tube is tilted and placed on a support so that the flat end of the aluminum tube is supported on the vertical support side bar, and the round end of the aluminum tube is adapted to the adaptation tray. The cold-drawn oil in the aluminum tube is collected and recovered through the oil recovery storage block, so that the cold-drawn oil in the aluminum tube enters the interior of the oil recovery storage block through the oil collection hole.

[0007] In some embodiments, the cold-drawn oil cleaning device further includes a negative pressure suction device with an air suction nozzle mounted on the adapter tray. The air suction nozzle extends into the round end of the aluminum tube and is used to cause the cold-drawn oil in the aluminum tube to flow to the adapter tray during suction.

[0008] In some embodiments, the following steps are included between the tilting rack treatment and the oil collection and recovery treatment: The negative pressure suction device is used to draw air and clean the oil from the round end of the aluminum tube, so that the cold-drawn oil inside the aluminum tube flows to the adapter tray.

[0009] In some embodiments, the negative pressure suction device is used to remove oil from the round end of the aluminum tube, including the following operations: Power is supplied to the negative pressure suction device to start it. The suction nozzle is used to draw oil from the round end of the aluminum tube, thereby generating a traction airflow inside the aluminum tube.

[0010] In some embodiments, the cold-drawn oil cleaning device further includes a warm oil pad, which is inclinedly disposed on the right-angle bracket and is used to contact the outer peripheral wall of the aluminum tube.

[0011] In some embodiments, the following steps are included between the tilting rack treatment and the oil collection and recovery treatment: The cold-drawn oil inside the aluminum tube is heated and liquefied by the hot oil pad to liquefy the solidified cold-drawn oil inside the aluminum tube.

[0012] In some embodiments, the bottom end of the warm oil pad is fixed to the adapter tray, the top end of the warm oil pad is connected to the vertical support side rod, and an arc-shaped heat conduction groove is formed on the warm oil pad for accommodating the aluminum tube.

[0013] In some embodiments, the heating and liquefaction treatment of the cold-drawn oil in the aluminum tube through the warm oil pad includes the following operations: The aluminum tube is placed against the wall of the arc-shaped heat conduction groove so that the groove wall of the arc-shaped heat conduction groove contacts the peripheral wall of the aluminum tube. The aluminum tube is heated against the wall using the warm oil pad to raise its temperature.

[0014] In some embodiments, the heating temperature of the warm oil pad is located between the pour point and the boiling point of the cold-drawn oil.

[0015] A vehicle-mounted lens includes an aluminum housing, which is obtained by the aluminum tube degreasing method based on the cold-drawing oil cleaning device of any of the above embodiments.

[0016] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned aluminum tube degreasing method based on a cold-drawing oil cleaning device can be understood as follows: by tilting the aluminum tube, it is positioned downwards from the flat end to the round end, thereby altering the flow direction of residual cold-drawing oil within the tube. This causes more and faster flow of the oil towards the round end under gravity, where the inner diameter is larger than that of the flat end, reducing obstruction to the oil's flow. Consequently, less oil remains in the tube, reducing the amount of harmful fumes generated from the combustion of residual oil during the aluminum tube cutting process, thus mitigating environmental pollution during automotive lens manufacturing. Subsequently, an oil recovery storage block collects and recovers the cold-drawing oil from the aluminum tube. This allows more of the oil collected on the adapter tray to be collected within the oil recovery storage block through the collection holes, reducing waste or pollution caused by external discharge of cold-drawing oil.

[0020] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] This disclosure provides a method for degreasing aluminum tubes based on a cold-drawn oil cleaning device. The method utilizes a cold-drawn oil cleaning device. Specifically, the cold-drawn oil cleaning device includes a right-angle bracket, an oil recovery storage block, and an adapter tray. The right-angle bracket includes a horizontal base and a vertical support rod. The vertical support rod is fixedly installed on the first side of the horizontal base and is perpendicular to the horizontal base. The vertical support rod is used to support the flat end of the aluminum tube. The oil recovery storage block has a placement slope and is fixedly installed on the second side of the horizontal base. The placement slope is positioned opposite to the vertical support rod. The adapter tray is installed on the placement slope and is used to fit the round end of the aluminum tube. The adapter tray has an oil collection hole that communicates with the interior of the oil recovery storage block.

[0024] The above-mentioned method for removing oil from aluminum tubes based on a cold-drawing oil cleaning device includes: tilting the aluminum tubes so that the flat end of the aluminum tubes is mounted on the vertical support side rods and the round end of the aluminum tubes is adapted to the matching tray; collecting and recovering the cold-drawing oil in the aluminum tubes through an oil recovery storage block so that the cold-drawing oil in the aluminum tubes enters the interior of the oil recovery storage block through the oil collection hole.

[0025] It is understandable that by tilting the aluminum tube, it can be tilted downwards from the flat end to the round end, thereby changing the flow direction of the residual cold-drawing oil inside the aluminum tube. This allows more and faster cold-drawing oil to flow towards the round end under the influence of gravity. The inner diameter of the round end is larger than that of the flat end, thus reducing the obstruction to the flow of cold-drawing oil. Afterwards, the round end of the aluminum tube is cleaned by suction using a negative pressure suction device, which allows the residual cold-drawing oil inside the aluminum tube to flow towards the round end even faster under the influence of airflow. This results in less residual cold-drawing oil inside the aluminum tube, thereby reducing the amount of harmful fumes generated by the combustion of residual cold-drawing oil during the aluminum tube cutting process, and thus mitigating the environmental pollution caused by the manufacturing process of automotive lenses.

[0026] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 2 to 4One embodiment of the aluminum tube degreasing method based on the cold-drawing oil cleaning device is performed using the cold-drawing oil cleaning device. Specifically, the aforementioned cold-drawn oil cleaning device includes a right-angle bracket 100, an oil recovery storage block 200, and an adapter tray 300. The right-angle bracket 100 includes a horizontal base 110 and a vertical support rod 120. The vertical support rod 120 is fixedly installed on the first side of the horizontal base 110 and is perpendicular to the horizontal base 110. The vertical support rod 120 is used to support the flat end 101 of the aluminum tube 10. The oil recovery storage block 200 has a placement slope 210 and is fixedly installed on the second side of the horizontal base 110. The placement slope 210 and the vertical support rod 120 are positioned opposite each other. The adapter tray 300 is installed on the placement slope 210 and is used to fit the round end 102 of the aluminum tube 10. The adapter tray 300 has an oil collection hole 310, which is connected to the interior of the oil recovery storage block 200. The aforementioned cold-drawn oil cleaning device is applicable to the following aluminum tube degreasing method based on the cold-drawn oil cleaning device.

[0027] The above-mentioned aluminum tube degreasing method based on the cold-drawn oil cleaning device includes some or all of the following steps: The aluminum tube 10 is tilted and mounted so that the flat end 101 of the aluminum tube 10 is mounted on the vertical support side rod 120, and the round end 102 of the aluminum tube 10 is adapted to the adapting tray 300. Please see Figure 2 In this embodiment, after the aluminum tube 10 is coated with cold drawing oil, the starting end of the cold drawing on the aluminum tube 10 is flattened to form a flat end 101. The flat end 101 of the aluminum tube 10 is the end that first enters the cold drawing mold during cold drawing. The inner diameter of the flat end 101 of the aluminum tube 10 is smaller than the inner diameter of other parts of the aluminum tube 10. The round end 102 of the aluminum tube 10 is the other end of the aluminum tube 10 relative to the flat end 101. The round end 102 of the aluminum tube 10 maintains the original shape and inner diameter of the aluminum tube 10, that is, the inner diameter of the round end 102 of the aluminum tube 10 is larger than the inner diameter of the flat end 101 of the aluminum tube 10. By tilting the aluminum tube 10, the flat end 101 of the aluminum tube 10 can be mounted on the vertical support rod 120, and the round end 102 of the aluminum tube 10 can be adapted to the adapter tray 300 on the placement slope 210 of the oil recovery storage block 200. The vertical support rod 120 is set perpendicular to the horizontal base 110, and the placement slope 210 is set opposite to the vertical support rod 120. In this way, the aluminum tube 10 will be tilted downward from the flat end 101 to the round end 102, thereby changing the flow direction of the residual cold-drawn oil in the aluminum tube 10, so that the cold-drawn oil will flow more and faster to the round end 102 under the action of gravity, thereby reducing the obstruction of the flat end 101 to the cold-drawn oil.

[0028] The cold-drawn oil in the aluminum tube 10 is collected and recovered by the oil recovery storage block 200, so that the cold-drawn oil in the aluminum tube 10 enters the interior of the oil recovery storage block 200 through the oil collection hole 310.

[0029] Please see Figure 3 In this embodiment, after the aluminum tube 10 is tilted, it is tilted downwards from the flat end 101 to the round end 102, thereby changing the flow direction of the residual cold-drawn oil inside the aluminum tube 10. This causes more and faster cold-drawn oil to flow towards the round end 102 under the influence of gravity. Since the oil collection hole 310 on the adapter tray 300 is connected to the inside of the oil recovery storage block 200, the oil recovery storage block 200 collects and recovers the cold-drawn oil inside the aluminum tube 10. This allows more of the cold-drawn oil collected on the adapter tray 300 to be collected inside the oil recovery storage block 200 through the oil collection hole 310, thus reducing waste or pollution caused by the discharge of cold-drawn oil.

[0030] It is understandable that by tilting the aluminum tube 10, it can be tilted downwards from the flat end 101 to the round end 102, thereby changing the flow direction of the residual cold-drawing oil inside the aluminum tube 10. This allows more and faster cold-drawing oil to flow towards the round end 102 under gravity. The inner diameter of the round end 102 is larger than that of the flat end 101, thus reducing the obstruction to the flow of cold-drawing oil. Consequently, less cold-drawing oil remains inside the aluminum tube 10, reducing the amount of harmful fumes generated by the combustion of residual cold-drawing oil during the aluminum tube cutting process, and mitigating environmental pollution during the manufacturing of automotive lenses. Subsequently, the cold-drawing oil inside the aluminum tube 10 is collected and recovered using the oil recovery storage block 200. This allows more of the cold-drawing oil collected on the adapter tray 300 to be collected inside the oil recovery storage block 200 through the oil collection hole 310, reducing waste or pollution caused by the discharge of cold-drawing oil.

[0031] Please see Figure 2In some embodiments, the cold-drawn oil cleaning device further includes a negative pressure suction device 400, which has a suction nozzle 410 mounted on an adapter tray 300. The suction nozzle 410 extends into the round end 102 of the aluminum tube 10 and is used to cause the cold-drawn oil in the aluminum tube 10 to flow toward the adapter tray 300 during suction. It is understandable that, since the suction nozzle 410 of the negative pressure suction device 400 is installed on the adapter tray 300, and the suction nozzle 410 extends into the round end 102 of the aluminum tube 10, while the flat end 101 of the aluminum tube 10 is connected to the outside, after the negative pressure suction device 400 is activated, the suction nozzle 410 of the negative pressure suction device 400 can suction the round end 102 of the aluminum tube 10. At this time, the flat end 101 of the aluminum tube 10 will draw air to the outside, thereby forming a traction airflow inside the aluminum tube 10. The traction airflow flows from the flat end of the aluminum tube 10. The airflow flows from end 101 to the opening of the round aluminum tube 10, meaning the direction of the airflow is the same as the direction of inclination of the aluminum tube 10. In this way, the cold-drawn oil adhering to the inner wall of the aluminum tube 10 can flow more quickly downward along the inner wall of the aluminum tube 10 from the flat end 101 to the round end 102 under the action of the airflow. The inner diameter of the round end 102 is larger than the inner diameter of the flat end 101, and the round end 102 provides less resistance to the flow of cold-drawn oil. This allows more and faster removal of the cold-drawn oil remaining in the aluminum tube 10.

[0032] In some embodiments, the following steps are included between the tilting rack treatment and the oil collection and recovery treatment: The negative pressure suction device 400 performs air suction and oil removal treatment on the round end 102 of the aluminum tube 10, so that the cold-drawn oil in the aluminum tube 10 flows to the adapter tray 300.

[0033] Please see Figure 2 In this embodiment, after the round end 102 of the aluminum tube 10 is fitted onto the adapter tray 300, the aluminum tube 10 will be inclined downwards from the flat end 101 to the round end 102. Since the suction nozzle 410 of the negative pressure suction device 400 is installed on the adapter tray 300, the suction nozzle 410 extends into the round end 102 of the aluminum tube 10. The negative pressure suction device 400 performs suction and oil removal treatment on the round end 102 of the aluminum tube 10. The flat end 101 of the aluminum tube 10 is connected to the outside, i.e., by activating the negative pressure suction device 400... The suction nozzle 410 of the negative pressure suction device 400 can generate an airflow from the flat end 101 to the round end 102 inside the aluminum tube 10. In this way, the cold-drawn oil adhering to the inner wall of the aluminum tube 10 can flow more quickly downward along the inner wall of the aluminum tube 10 from the flat end 101 to the round end 102 under the action of the airflow. The inner diameter of the round end 102 is larger than the inner diameter of the flat end 101, and the round end 102 has less obstruction to the flow of cold-drawn oil, so that more and faster cold-drawn oil remaining in the aluminum tube 10 can be cleaned out of the aluminum tube 10.

[0034] In some embodiments, the round end 102 of the aluminum tube 10 is cleaned by suction using a negative pressure suction device 400, including the following operations: Perform power distribution operation on the negative pressure suction device 400 to start the negative pressure suction device 400; Please see Figure 2 In this embodiment, the negative pressure suction device 400 can be a traditional electric suction device, so the negative pressure suction device 400 will not be described in detail here. By performing a power distribution operation on the negative pressure suction device 400, that is, by plugging the plug of the negative pressure suction device 400 into a power strip, the motor in the negative pressure suction device 400 can be connected to the power supply, thereby starting the negative pressure suction device 400 by starting the motor. This allows for quick and convenient startup of the negative pressure suction device 400.

[0035] The suction nozzle 410 is used to draw oil from the round end 102 of the aluminum tube 10, so as to generate a traction airflow inside the aluminum tube 10.

[0036] Please see Figure 2 In this embodiment, when the cold-drawn oil flows along the inner wall of the aluminum tube 10 towards the round end 102 under the action of gravity, since the suction nozzle 410 of the negative pressure suction device 400 extends into the round end 102 of the aluminum tube 10, the suction nozzle 410 can configure the suction force generated by the negative pressure suction device 400 at the round end 102 of the aluminum tube 10. The suction nozzle 410 generates a traction airflow in the aluminum tube 10. The traction airflow flows from the flat end 101 to the round end 102. The direction of the traction airflow is similar to the direction of gravity. The cold-drawn oil remaining in the aluminum tube 10 can flow towards the round end 102 more quickly under the superposition of the traction airflow and gravity, thereby making the cold-drawn oil residue in the aluminum tube 10 less. The cold-drawn oil can be more and faster to gather on the adapter tray 300.

[0037] Please see Figure 4In some embodiments, there are multiple oil collection holes 310, which are distributed at intervals along the edge of the adapter tray 300. Each oil collection hole 310 is located near the inner edge of the corresponding portion of the round end 102. The air intake 410 is located at the center of the adapter tray 300. The air inlet of the air intake 410 faces the inside of the round end 102 and is coaxially arranged with the aluminum tube 10. It is understandable that, since multiple oil collection holes 310 are distributed at intervals along the edge of the adapter tray 300, and the air suction nozzle 410 is set at the center of the adapter tray 300, multiple oil collection holes 310 can surround the air suction nozzle 410 together. Each oil collection hole 310 is set close to the inner edge of the corresponding part of the round end 102. When the air inlet of the air suction nozzle 410 draws air, a traction airflow is formed in the aluminum tube 10. The traction airflow can make the cold-drawn oil flow along the inner wall of the aluminum tube 10. In this way, the cold-drawn oil at the inner edge of the corresponding part of the round end 102 can be collected through each oil collection hole 310, so as to improve the recovery efficiency of the cold-drawn oil.

[0038] Normally, when air is drawn into the round end 102 of the aluminum tube 10 through the suction nozzle 410, air needs to be supplied into the aluminum tube 10 through the flat end 101 of the aluminum tube 10 in order to form a stable traction airflow inside the aluminum tube 10. However, since the inner diameter of the aluminum tube 10 at the flat end 101 is smaller than the inner diameter of the aluminum tube 10 at the round end 102, and the aluminum tube 10 is generally several meters or more, when the exhaust speed of the round end 102 of the aluminum tube 10 is too fast, the flat end 101 of the aluminum tube 10 will not be supplied with air in time. This will cause negative pressure to appear inside the aluminum tube 10. Under this condition, the aluminum tube 10 is easily deformed by atmospheric pressure.

[0039] Please see Figure 3 In order to reduce the amount of deformation of the aluminum tube 10 due to atmospheric pressure, in some embodiments, the cold-drawing oil cleaning device further includes an air supply nozzle 420, which is disposed at the flat end 101 of the aluminum tube 10, and the air outlet of the air supply nozzle 420 faces the air inlet of the suction nozzle 410; the air inlet of the air supply nozzle 420 is used to connect to the air outlet of an external device to supply air to the aluminum tube 10.

[0040] It is understandable that at the flat end 101 of the aluminum tube 10, since the outlet of the air supply nozzle 420 faces the inlet of the air intake nozzle 410, when the gas in the aluminum tube 10 is insufficient, air can be supplied to the flat end 101 of the aluminum tube 10 through the outlet of the air supply nozzle 420, thereby increasing the gas content in the aluminum tube 10 and increasing the pressure in the aluminum tube 10, so as to reduce the amount of deformation of the aluminum tube 10 by atmospheric pressure.

[0041] Typically, the amount of air supplied to the aluminum tube 10 by the air supply nozzle 420 is not equal to the amount of air blown into the aluminum tube 10 by the air intake nozzle 410. If too much gas is supplied to the aluminum tube 10, it is easy to cause a high-pressure state inside the aluminum tube 10. At this time, the flow rate of the traction airflow will be difficult to control, and the aluminum tube 10 is also prone to explosion risk.

[0042] Please see Figure 3 To improve the control of the traction airflow velocity, in one embodiment, the air inlet of the supplementary air nozzle 420 is connected to the air outlet of the negative pressure suction device 400, and the air inlet of the suction nozzle 410 is the air inlet of the negative pressure suction device 400. It can be understood that because the air inlet of the supplementary air nozzle 420 is connected to the air outlet of the negative pressure suction device 400, and the air inlet of the suction nozzle 410 is the air inlet of the negative pressure suction device 400, the gas drawn into the aluminum tube 10 by the negative pressure suction device 400 through the suction nozzle 410 can re-enter the aluminum tube 10 through the air inlet of the supplementary air nozzle 420. This significantly reduces the difference in the amount of gas entering and leaving the aluminum tube 10, thereby improving the control of the traction airflow velocity and reducing the risk of explosion of the aluminum tube 10.

[0043] Typically, due to the low winter temperatures, the cold-drawn oil remaining in the aluminum tube 10 tends to solidify on the inner wall of the aluminum tube 10, making it difficult for it to flow along the tube wall of the aluminum tube 10 to the adapter tray 300 under the influence of gravity or traction airflow.

[0044] Please see Figure 2 To improve the fluidity of cold-drawn oil at low temperatures, in some embodiments, the cold-drawn oil cleaning device further includes a warm oil pad 500. The warm oil pad 500 is inclinedly disposed on the right-angle bracket 100 and is used to contact the outer peripheral wall of the aluminum tube 10. It can be understood that since the warm oil pad 500, inclinedly disposed on the right-angle bracket 100, is in contact with the outer peripheral wall of the aluminum tube 10, when the warm oil pad 500 is activated, it can heat the outer peripheral wall of the aluminum tube 10. The aluminum tube 10 transfers heat to its inner wall, thereby causing the cold-drawn oil solidified on the inner wall of the aluminum tube 10 to re-liquefy. This enhances the fluidity of the cold-drawn oil on the inner wall of the aluminum tube 10, allowing it to accumulate on the adapter tray 300 more quickly and in greater quantities.

[0045] In some embodiments, the following steps are included between the tilting rack treatment and the oil collection and recovery treatment: The cold-drawn oil inside the aluminum tube 10 is heated and liquefied by a hot oil pad 500 to liquefy the solidified cold-drawn oil inside the aluminum tube 10.

[0046] Please see Figure 2 and Figure 5In this embodiment, since the warm oil pad 500, which is inclinedly set on the right-angle bracket 100, is in contact with the outer peripheral wall of the aluminum tube 10, when the warm oil pad 500 is activated, the warm oil pad 500 can heat the outer peripheral wall of the aluminum tube 10. The aluminum tube 10 transfers heat to the inner wall of the aluminum tube 10, thereby allowing the cold-drawn oil solidified on the inner wall of the aluminum tube 10 to be heated and reliquefied. In this way, the fluidity of the cold-drawn oil on the inner wall of the aluminum tube 10 will be enhanced, and it can gather more and faster on the adapter tray 300.

[0047] Please see Figure 3 and Figure 4 In some embodiments, the bottom end of the warm oil pad 500 is fixed to the adapter tray 300, and the top end of the warm oil pad 500 is connected to the vertical support side rod 120. An arc-shaped heat conduction groove 501 is formed on the warm oil pad 500, which is used to accommodate the aluminum tube 10. It can be understood that since the bottom end of the warm oil pad 500 is fixed to the adapter tray 300 and the top end of the warm oil pad 500 is connected to the vertical support side rod 120, both ends of the warm oil pad 500 can be securely fixed, so that the warm oil pad 500 can be securely tilted and installed on the right-angle bracket 100. In this way, the aluminum tube 10 can be stably accommodated by the arc-shaped heat conduction groove 501 formed on the warm oil pad 500, thereby further improving the stability of the aluminum tube 10 placed on the right-angle bracket 100.

[0048] In some embodiments, the cold-drawn oil in the aluminum tube 10 is heated and liquefied by a warm oil pad 500, including the following operations: The aluminum tube 10 is placed against the wall by the arc-shaped heat conduction groove 501 so that the groove wall of the arc-shaped heat conduction groove 501 contacts the peripheral wall of the aluminum tube 10. Please see Figure 5 In this embodiment, the curvature of the arc-shaped heat conduction groove 501 is adapted to the curvature of the outer peripheral wall of the aluminum tube 10. After the aluminum tube 10 is tilted and mounted, the aluminum tube 10 will be tilted downward from the flat end 101 to the round end 102. The arc-shaped heat conduction groove 501 is used to accommodate the aluminum tube 10 against the wall, so that the groove wall of the arc-shaped heat conduction groove 501 is adapted to and adheres to the outer peripheral wall of the aluminum tube 10. This can increase the contact area between the groove wall of the arc-shaped heat conduction groove 501 and the outer peripheral wall of the aluminum tube 10, thereby improving the support and fixing effect of the hot oil pad 500 on the aluminum tube 10.

[0049] The aluminum tube 10 is heated against the wall by a warm oil pad 500 to raise its temperature.

[0050] Please see Figure 5In this embodiment, after the wall of the arc-shaped heat-conducting groove 501 is in close contact with the outer peripheral wall of the aluminum tube 10, the aluminum tube 10 is heated by the warm oil pad 500. Specifically, the heat generated by the warm oil pad 500 can be conducted to the outer peripheral wall of the aluminum tube 10 more quickly and in greater quantities through the wall of the arc-shaped heat-conducting groove 501. The aluminum tube 10 transfers the heat to the inner wall of the aluminum tube 10, thereby allowing the cold-drawn oil solidified on the inner wall of the aluminum tube 10 to be heated and reliquefied. In this way, the fluidity of the cold-drawn oil on the inner wall of the aluminum tube 10 will be enhanced, and it can accumulate on the adapter tray 300 more quickly and in greater quantities.

[0051] In some embodiments, the heating temperature of the warm oil pad 500 is located between the pour point and boiling point of the cold-drawn oil. It is understood that by maintaining the heating temperature of the warm oil pad 500 between the pour point and boiling point of the cold-drawn oil—specifically, the heating temperature of the warm oil pad 500 being higher than the pour point of the cold-drawn oil—the cold-drawn oil can be heated to a liquid state through the warm oil pad 500, thereby improving the fluidity of the cold-drawn oil within the aluminum tube 10. Furthermore, the heating temperature of the warm oil pad 500 being lower than the boiling point of the cold-drawn oil prevents the cold-drawn oil from vaporizing and forming harmful fumes during the heating process, thus reducing environmental pollution. In this embodiment, the cold-drawn oil is a mixture of mineral oil, sulfurized lard, sulfurized fatty acid esters, sulfurized isobutylene, lanthanum dimer, and sodium benzoate. The pour point of the cold-drawn oil is -5°C, and the boiling point is 200°C.

[0052] Please see Figures 2 to 4 This disclosure also provides a vehicle-mounted lens, including an aluminum housing, which is obtained using the aluminum tube degreasing method based on the cold-drawing oil cleaning device of any of the above embodiments. It is understood that by tilting the aluminum tube 10, it can be tilted downwards from the flat end 101 to the round end 102, thereby changing the flow direction of the residual cold-drawing oil inside the aluminum tube 10. This allows more and faster cold-drawing oil to flow towards the round end 102 under gravity. The inner diameter of the round end 102 is larger than the inner diameter of the flat end 101, thus reducing the obstruction to the flow of cold-drawing oil. Consequently, less cold-drawing oil remains inside the aluminum tube 10, thereby reducing the amount of harmful fumes generated by the combustion of residual cold-drawing oil during the aluminum tube 10 cutting process, and mitigating environmental pollution during the manufacturing process of the vehicle-mounted lens. Then, the cold-drawn oil in the aluminum tube 10 is collected and recycled through the oil recovery storage block 200. This allows more of the cold-drawn oil that accumulates on the adapter tray 300 to be collected inside the oil recovery storage block 200 through the oil collection hole 310, thereby reducing the waste or pollution caused by the discharge of cold-drawn oil.

[0053] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned aluminum tube degreasing method based on a cold-drawing oil cleaning device, by tilting the aluminum tube 10, allows it to be tilted downwards from the flat end 101 to the round end 102, thereby changing the flow direction of the residual cold-drawing oil inside the aluminum tube 10. This causes more and faster cold-drawing oil to flow towards the round end 102 under gravity. The inner diameter of the round end 102 is larger than that of the flat end 101, thus reducing the obstruction to the flow of cold-drawing oil. Consequently, less cold-drawing oil remains inside the aluminum tube 10, reducing the amount of harmful fumes generated by the combustion of residual cold-drawing oil during the aluminum tube cutting process, and mitigating environmental pollution during the manufacturing of automotive lenses. Subsequently, the cold-drawing oil inside the aluminum tube 10 is collected and recovered using an oil recovery storage block 200. This allows more of the cold-drawing oil collected on the adapter tray 300 to be collected inside the oil recovery storage block 200 through the oil collection hole 310, reducing waste or pollution caused by the discharge of cold-drawing oil.

[0054] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
