Description

Technical Field

[0001] This disclosure relates to the technical field of manufacturing aluminum lens barrels for automotive lenses, and in particular to a cleaning and straightening device and method for the aluminum lens barrels of automotive lenses. Background Technology

[0002] The surge in demand for automotive lenses driven by automotive intelligence has led to a surge in demand for their core component: aluminum lens barrel blanks. The excellent thermal conductivity and corrosion resistance of aluminum alloys have made aluminum the mainstream material. Automotive lenses have stringent requirements for the precision and strength of the aluminum shell—the smoothness and roundness of the inner wall directly affect optical coaxiality, and structural stability must withstand vehicle vibrations and high / low temperature cycles. This has resulted in a core production process of "aluminum extrusion - inner wall polishing - cold drawing and straightening." This process uses aluminum ingots as raw material. First, aluminum tubes are directly formed through aluminum extrusion (using a tubular die with a mandrel) (no subsequent perforation required). Then, the inner wall of the aluminum tube is polished to remove residual die marks from the extrusion process, ensuring the inner wall precision meets standards. After polishing, the tubes are cut into fixed-length blanks according to specifications, and then proceed to the cold drawing and straightening process. The inner diameter of the straightening hole in the cold drawing straightening equipment needs to be precisely controlled, and should be 0.1mm to 0.15mm smaller than the outer diameter of the aluminum lens tube blank. The straightness of the blank is corrected by interference fit. In order to allow the blank to pass smoothly into the straightening hole, one end of the blank needs to be narrowed by hammering or squeezing. Finally, a qualified blank with accurate dimensions and stable structure is obtained by cold drawing straightening.

[0003] Most aluminum lens barrel blank straightening equipment on the market mainly includes a straightening die, a supporting inner die head, and a drawing device. The straightening die has a straightening hole. The supporting inner die head is used to extend into the cavity of the aluminum lens barrel blank before the cold drawing and straightening operation to support the inner wall of the aluminum lens barrel blank and prevent deformation during the cold drawing and straightening process. The clamping end of the drawing device is used to clamp the constricted end of the aluminum lens barrel blank and drag the constricted end away from the outer die head, thereby completing the cold drawing and straightening operation of the aluminum lens barrel blank. Figures 1 to 3 As shown.

[0004] However, during the processes of polishing, cutting, and tapping to reduce the diameter of the aluminum tube, a large amount of aluminum shavings and burrs will adhere to the inner wall of the aluminum lens tube blank. If the aluminum shavings and burrs are not cleaned properly, the aluminum lens tube blank will be easily squeezed by the inner die head during the cold drawing and straightening operation, resulting in scratches on the inner wall of the die and affecting the production quality of the aluminum lens tube blank. Therefore, aluminum shavings must be cleaned before the aluminum lens tube blank is cold drawn and straightened to remove the aluminum shavings and burrs from the inner wall of the aluminum lens tube blank.

[0005] Currently, the industry relies heavily on manual handheld air blowers to clean aluminum shavings and burrs. This method is not only inefficient, but also ineffective in removing tightly attached aluminum shavings and burrs. Furthermore, due to the narrow opening at the constricted end of the aluminum lens barrel blank, it is impossible to clean the aluminum shavings and burrs inside the barrel cavity through this opening, making it difficult for the air blower to reach into the barrel cavity for cleaning. This significantly reduces the production quality and efficiency of aluminum lens barrels for automotive lenses. Summary of the Invention

[0006] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a cleaning and straightening device and method for aluminum lens barrels used in automotive lenses that can effectively improve the production quality and efficiency of aluminum lens barrels.

The cleaning component includes a connecting rod and an air bladder. The cleaning end of the cleaning component is located on the air bladder. The air bladder end of the air bladder is sleeved and fixed to the mounting end of the connecting rod. The air bladder end of the air bladder is used to extend into the cavity of the aluminum lens barrel blank during the cleaning operation.

[0008] In one embodiment, the cross-sectional dimension of the cleaning component is smaller than the cross-sectional dimension of the cavity of the aluminum lens barrel blank.

[0009] In one embodiment, the outer peripheral wall of the mounting end of the connecting rod is formed with an annular mounting groove, and the airbag end of the airbag component is accommodated and installed in the annular mounting groove.

[0010] In one embodiment, the airbag component includes an annular airbag portion and an air pressure regulating portion.

The air pressure regulating portion is used to adjust the internal air pressure of the annular airbag portion. The annular airbag portion is installed and fixed at the bottom of the annular mounting groove. The air pressure regulating portion is installed and fixed on the outer peripheral wall of the connecting rod.

[0011] In one embodiment, the outer surface of the annular airbag portion is covered with an elastic cleaning layer.

[0012] In one embodiment, an elastic protective layer is provided between the elastic cleaning layer and the outer surface of the annular airbag portion.

[0013] In one embodiment, the connecting rod is a telescopic rod, and the mounting end of the connecting rod is located at the telescopic end of the telescopic rod.

[0014] In one embodiment, the connecting rod includes a mounting tube, a telescopic part, and a driving cylinder. The first end of the mounting tube is sleeved on the first end of the telescopic part, and the outer peripheral wall of the first end of the telescopic part slides against the inner peripheral wall of the mounting tube. The fixed end of the driving cylinder is installed and fixed to the second end of the mounting tube, and the driving end of the driving cylinder is disposed inside the mounting tube and fixedly connected to the end of the first end of the telescopic part. The driving end of the driving cylinder is used to drive the telescopic part to slide relative to the mounting tube. The airbag end of the airbag component is disposed at the second end of the telescopic part.

[0015] In one embodiment, the cold drawing straightening assembly includes a straightening die, a supporting inner die head, and a drawing clamp. The straightening die has a straightening hole. The supporting inner die head is adapted to fit the cavity of the aluminum lens barrel blank and extends into the cavity and abuts against the inner peripheral wall of the cavity. The drawing clamp is used to clamp and fix the constricted end of the aluminum lens barrel blank and drag the aluminum lens barrel blank through the straightening hole to perform a straightening operation on the aluminum lens barrel blank.

[0016] A method for cleaning and straightening an aluminum lens barrel for automotive lenses, comprising the cleaning and straightening equipment for an aluminum lens barrel for automotive lenses as described in any of the above embodiments, wherein the method for cleaning and straightening an aluminum lens barrel for automotive lenses includes: Obtain the aluminum mirror tube blank after the necking operation is completed; The mounting end of the connecting rod is inserted into the cavity of the aluminum lens barrel blank and moved toward the constricted end of the aluminum lens barrel blank until the connecting rod abuts against the constricted end of the aluminum lens barrel blank, so as to drive the airbag end of the airbag component to the preset position of the cavity. Activate the airbag component to inflate the airbag end until it presses against the inner circumferential wall of the cylindrical cavity; Pull the connecting rod outward to move the airbag end of the airbag component away from the constricted end of the aluminum lens barrel blank until it detaches from the barrel cavity.

At the same time, the cleaning component can also effectively extend into the cylinder cavity for cleaning, thereby greatly improving the cleaning effect and cleaning efficiency of the cleaning and straightening equipment for aluminum lens barrels of automotive lenses, and thus greatly improving the production quality and production efficiency of aluminum lens barrels.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: like Figures 4 to 10As shown, an embodiment of a cleaning and straightening device for an aluminum lens barrel of an automotive lens includes a cold-drawing straightening assembly (not shown) and a cleaning assembly 10. The cold-drawing straightening assembly is used to straighten the aluminum lens barrel blank (not shown). The cleaning end of the cleaning assembly 10 is used to clean aluminum shavings and burrs on the inner wall of the aluminum lens barrel blank. The cleaning assembly 10 includes a connecting rod 110 and an airbag component 120. The cleaning end of the cleaning assembly 10 is located on the airbag component 120, and the airbag end of the airbag component 120 is sleeved with... Fixed to the mounting end of the connecting rod 110, the airbag end of the airbag component 120 is used to extend into the cavity of the aluminum lens barrel blank during cleaning operations. When it is necessary to clean aluminum shavings and burrs on the cavity of the aluminum lens barrel blank, simply insert the mounting end of the connecting rod 110 into the cavity of the aluminum lens barrel blank to drive the airbag end of the airbag component 120 into the preset position in the cavity. Then, the airbag component 120 is opened, causing the airbag end of the airbag component 120 to inflate, thereby allowing... The airbag end of the airbag component 120 is press-fitted against the inner circumferential wall of the aluminum lens barrel blank. Finally, the mounting end of the connecting rod 110 is pulled out of the cylinder cavity away from the constricted end of the aluminum lens barrel blank. This allows the airbag end of the airbag component 120 to remove aluminum shavings and burrs from the inner circumferential wall of the aluminum lens barrel blank from the cylinder cavity. Compared with the manual hand-held air blowing cleaning method in the above-mentioned related technologies, the cleaning and straightening equipment for aluminum lens barrels of automotive lenses disclosed in this invention can not only effectively clean aluminum shavings and burrs on the inner wall of the cylinder cavity, thus avoiding the risk of scratches on the inner wall of the aluminum lens barrel blank due to aluminum shavings and burrs adhering to the inner wall of the cylinder cavity during cold drawing and straightening operations, but also effectively reduce the cleaning difficulty of the aluminum lens barrel blank. At the same time, the cleaning component 10 can also effectively extend into the cylinder cavity for cleaning, thereby greatly improving the cleaning effect and cleaning efficiency of the cleaning and straightening equipment for aluminum lens barrels of automotive lenses, and thus greatly improving the production quality and production efficiency of aluminum lens barrels.

[0025] The aforementioned cleaning and straightening device for aluminum lens barrels of automotive lenses features a cleaning component 10 with its cleaning end located on the airbag component 120. The airbag end of the airbag component 120 is sleeved and fixed to the mounting end of the connecting rod 110. The airbag end of the airbag component 120 is used to extend into the cavity of the aluminum lens barrel blank during cleaning operations. When cleaning aluminum shavings and burrs on the cavity of the aluminum lens barrel blank is required, the mounting end of the connecting rod 110 is first inserted into the cavity of the aluminum lens barrel blank to drive the airbag end of the airbag component 120 into a preset position within the cavity. Then, the airbag component 120 is opened, causing the airbag end of the airbag component 120 to expand, thereby causing the airbag end of the airbag component 120 to press against the inner circumferential wall of the aluminum lens barrel blank. Finally, the mounting end of the connecting rod 110 is moved away from the constriction of the aluminum lens barrel blank. By pulling the end out of the cylinder cavity, the airbag end of the airbag component 120 can remove aluminum shavings and burrs from the inner circumferential wall of the aluminum lens barrel blank. Compared with the manual hand-held air blowing cleaning method in the above-mentioned related technologies, the cleaning and straightening equipment for aluminum lens barrels of automotive lenses disclosed in this invention can not only effectively clean the aluminum shavings and burrs on the inner wall of the cylinder cavity, thus avoiding the risk of scratches on the inner wall of the aluminum lens barrel blank due to the adhesion of aluminum shavings and burrs during the cold drawing and straightening operation, but also effectively reduce the cleaning difficulty of the aluminum lens barrel blank. At the same time, the cleaning component 10 can also effectively extend into the cylinder cavity for cleaning, thereby greatly improving the cleaning effect and cleaning efficiency of the cleaning and straightening equipment for aluminum lens barrels of automotive lenses, and thus greatly improving the production quality and production efficiency of aluminum lens barrels.

[0026] It should be noted that the airbag component 120 is always in a retracted state before it is deployed.

[0027] like Figures 4 to 6 As shown, in one embodiment, the cross-sectional size of the cleaning component 10 is smaller than the cross-sectional size of the cavity of the aluminum lens barrel blank, so that the cleaning end of the cleaning component 10 can be inserted into the cavity, enabling the cleaning component 10 to effectively clean aluminum shavings and burrs on the inner wall of the cavity.

[0028] like Figures 4 to 6 As shown, in one embodiment, the cross-sectional dimension of the cleaning component 10 is larger than the cross-sectional dimension of the constricted end of the aluminum lens barrel blank. This ensures that when the cleaning end of the cleaning component 10 abuts against the constricted end of the aluminum lens barrel blank, it can be determined that the connecting rod 110 has driven the airbag end of the airbag component 120 to extend into the preset position of the barrel cavity. At the same time, it avoids the situation where the cross-sectional dimension of the constricted end of the aluminum lens barrel blank and the cross-sectional dimension of the barrel cavity are different, which would prevent the airbag end of the airbag component 120 from moving from the constricted end of the aluminum lens barrel blank into the barrel cavity and failing to effectively fit the inner wall of the barrel cavity. This not only greatly improves the cleaning effect of the aluminum lens barrel blank but also reduces the cleaning difficulty of the aluminum lens barrel blank.

[0029] like Figures 4 to 6 As shown, in one embodiment, an annular mounting groove 111 is formed on the outer peripheral wall of the mounting end of the connecting rod 110. The airbag end of the airbag component 120 is accommodated and installed in the annular mounting groove 111, so that the airbag end of the airbag component 120 can be retracted into the annular mounting groove 111 when it is in the retracted state. This not only reduces the overall volume of the cleaning assembly 10 and avoids movement interference between the airbag end of the airbag component 120 and the aluminum lens barrel blank during the process of extending the airbag end of the airbag component 120 into the barrel cavity, but also protects the airbag end of the airbag component 120 from being exposed to the outside when it is in the retracted state. Sharp objects can puncture and scratch, thus greatly improving the service life of the airbag component 120. At the same time, the annular mounting groove 111 can also limit the airbag end of the inflated airbag component 120 to reduce the movement of the airbag end of the inflated airbag component 120 during the process of detaching from the cylinder cavity. This prevents the airbag end of the inflated airbag component 120 from moving too much during the process of detaching from the cylinder cavity, which would cause a significant reduction in the fit between the airbag end of the inflated airbag component 120 and the inner wall of the cylinder cavity. This ensures that the cleaning component 10 can effectively clean the aluminum shavings and burrs on the inner wall of the cylinder cavity, thereby greatly improving the production quality of aluminum lens barrels.

[0030] like Figures 4 to 7 As shown, in one embodiment, a first rounded corner transition area 1111 is formed at the corner of the opening of the annular mounting groove 111 to prevent the corner of the opening of the annular mounting groove 111 from being too sharp and piercing and damaging the airbag end of the airbag component 120.

[0031] like Figures 4 to 8 As shown, in one embodiment, the airbag component 120 includes an annular airbag portion 121 and an air pressure regulating portion 122. The airbag end of the airbag component 120 is disposed in the annular airbag portion 121. The gas transmission end of the annular airbag portion 121 is connected to the air pressure regulating end of the air pressure regulating portion 122. The air pressure regulating portion 122 is used to adjust the internal air pressure of the annular airbag portion 121. The annular airbag portion 121 is installed and fixed at the bottom of the annular mounting groove 111. The air pressure regulating portion 122 is installed and fixed to the outer peripheral wall of the connecting rod 110, so that when... When the air pressure regulating unit 122 is turned on, it will introduce outside air into the interior of the annular airbag 121, causing the annular airbag 121 to expand rapidly and protrude out of the annular mounting groove 111. This allows the annular airbag 121 to press against the inner wall of the barrel cavity, effectively removing aluminum shavings and burrs from the inner wall of the aluminum barrel blank. When the air pressure regulating unit 122 is turned off, the internal air pressure of the annular airbag 121 is the same as the external air pressure, so that the annular airbag 121 is in a contracted state.

[0032] like Figure 4As shown, in one embodiment, the gas transmission end of the annular airbag 121 is connected to the air pressure regulating end of the air pressure regulating part 122 via a connecting pipe.

[0033] like Figure 8 As shown, in one embodiment, the internal pressure of the annular airbag portion 121 is 0.05MPa~0.15MPa. This pressure not only allows the annular airbag portion 121 to fit tightly against the inner wall of the cylinder cavity, enabling the annular airbag portion 121 to effectively remove aluminum shavings and burrs from the inner wall of the cylinder cavity, but also prevents excessive pressure between the annular airbag portion 121 and the inner wall of the cylinder cavity from causing indentations or even deformation of the inner wall of the cylinder cavity, thereby greatly improving the production quality of aluminum mirror tube blanks.

[0034] like Figure 4 As shown, in one embodiment, the pressure regulating unit 122 is a pressure pump, so that the pressure regulating unit 122 can accurately regulate and maintain the internal pressure of the annular airbag 121.

[0035] It should be noted that the operation of the pressure pump to precisely adjust and maintain the internal pressure value of the annular airbag 121 is existing technology, and will not be described in detail here.

[0036] like Figure 9 As shown, in one embodiment, the outer surface of the annular airbag portion 121 is covered with an elastic cleaning layer 1211. This elastic cleaning layer 1211, through its elastic properties, not only buffers and disperses the compressive force between the annular airbag portion 121 and the inner wall of the cylinder, but also automatically adapts to the shape of the inner wall of the cylinder. This allows the elastic cleaning layer 1211 to fit tightly against the inner wall of the cylinder, effectively removing aluminum shavings and burrs, thus significantly improving the production quality of the aluminum lens barrel blank. Simultaneously, the elastic cleaning layer 1211 effectively protects the annular airbag portion 121, reducing the risk of it being punctured or scratched by sharp objects, thereby extending its service life. like Figure 9 As shown, in one embodiment, the elastic cleaning layer 1211 is a polyurethane elastic cleaning layer 1211, a nitrile rubber elastic cleaning layer 1211, or a silicone rubber elastic cleaning layer 1211, so that the annular airbag portion 121 can have better elasticity and wear resistance, thereby improving the stability and service life of the cleaning component 10.

[0037] like Figure 9 As shown, in one embodiment, the thickness of the elastic cleaning layer 1211 is 0.8 mm to 1 mm.

[0038] like Figure 9As shown, in one embodiment, an elastic protective layer 1212 is provided between the elastic cleaning layer 1211 and the outer surface of the annular airbag portion 121 to further reduce the risk of the annular airbag portion 121 being punctured or scratched by a sharp object, thereby improving the service life of the annular airbag portion 121.

[0039] like Figure 9 As shown, in one embodiment, the elastic protective layer 1212 is a nylon elastic cloth protective layer, a thermoplastic polyurethane elastic film protective layer, or a nitrile rubber elastic sheet protective layer, so that the elastic protective layer 1212 can have better elasticity and tear resistance, thereby improving the protection of the annular airbag portion 121.

[0040] like Figure 9 As shown, in one embodiment, the thickness of the elastic protective layer 1212 is 0.1 mm to 0.2 mm.

[0041] like Figures 4 to 6 As shown, in one embodiment, the connecting rod 110 is a telescopic rod, and the mounting end of the connecting rod 110 is located at the telescopic end of the telescopic rod, so that the connecting rod 110 can reduce its overall volume through its own telescopic capacity.

[0042] like Figures 4 to 6As shown, in one embodiment, the connecting rod 110 includes an mounting tube 112, a telescopic part 113, and a driving cylinder 114. The first end of the mounting tube 112 is sleeved on the first end of the telescopic part 113, and the outer peripheral wall of the first end of the telescopic part 113 slides against the inner peripheral wall of the mounting tube 112. The fixed end of the driving cylinder 114 is fixedly mounted on the second end of the mounting tube 112, and the driving end of the driving cylinder 114 is disposed inside the mounting tube 112 and fixedly connected to the end of the first end of the telescopic part 113. The driving end of the driving cylinder 114 is used to drive the telescopic part 113 to slide relative to the mounting tube 112. The airbag end of the airbag component 120 is disposed on the second end of the telescopic part 113, so that when it is necessary to extend the airbag end of the airbag component 120 into the preset position of the cylinder cavity, it is only necessary to first move the second end of the telescopic part 113 away from the cylinder cavity from the aluminum mirror barrel blank. The openings of the constricted ends of the material are aligned, and then the telescopic part 113 is driven by the drive cylinder 114 to extend into the cylinder cavity and move towards the constricted end of the aluminum lens barrel blank until the end of the first end of the telescopic part 113 abuts against the constricted end of the aluminum lens barrel blank. Then the airbag part 120 is opened to limit the airbag end of the airbag part 120 to a preset position in the cylinder cavity. At the same time, the airbag end of the airbag part 120 is rapidly expanded and presses against the inner wall of the cylinder cavity. Then the telescopic part 113 is driven by the drive cylinder 114 to move away from the constricted end of the aluminum lens barrel blank until it returns to the initial position. This allows the airbag end of the airbag part 120 to scrape off the aluminum shavings and burrs on the inner wall of the cylinder cavity and carry them out of the cylinder cavity. The automation level of the cleaning component 10 is greatly improved, which in turn greatly improves the ease of use of the cleaning and straightening equipment for aluminum lens barrels of automotive lenses.

[0043] like Figures 4 to 6 As shown, in one embodiment, the outer peripheral wall of the telescopic part 113 is closely fitted with the inner peripheral wall of the mounting tube 112 so that the telescopic part 113 can remain stable during the sliding process relative to the mounting tube 112, reducing the risk of the telescopic part 113 scraping against the inner peripheral wall of the tube cavity, thereby improving the production quality of the aluminum lens tube.

[0044] like Figure 7 As shown, in one embodiment, a second rounded corner transition 1131 is formed at the corner of the second end of the telescopic part 113 to avoid the phenomenon that the end of the second end of the telescopic part 113 is too sharp and scratches the inner peripheral wall of the barrel cavity, thereby further improving the production quality of the aluminum barrel.

[0045] like Figures 4 to 6 As shown, in one embodiment, the drive cylinder 114 is detachably installed at the second end of the mounting tube 112 to facilitate the installation and removal of the drive cylinder 114, thereby greatly reducing the difficulty of replacing and maintaining the drive cylinder 114 and thus greatly improving the maintenance convenience of the cleaning and straightening equipment for the aluminum lens barrel of automotive lenses.

[0046] like Figures 4 to 6 As shown, in one embodiment, a positioning groove 1141 is formed on the side of the fixed end of the drive cylinder 114 facing the mounting tube 112. The second end of the mounting tube 112 is embedded in the positioning groove 1141, and the end of the second end of the mounting tube 112 abuts and is supported on the bottom of the positioning groove 1141, so that the drive cylinder 114 can be reliably supported and limited to the second end of the mounting tube 112. This allows the drive cylinder 114 to effectively drive the telescopic part 113 and the annular airbag part 121 to slide relative to the aluminum lens barrel blank when the mounting tube 112 is pulled out. The connecting rod 110 also includes a fastener (not shown), and the second end of the mounting tube 112... The outer peripheral wall has a threaded hole 1121 that communicates with the positioning groove 1141, and the outer peripheral wall of the drive cylinder 114 has a positioning hole 1142 that communicates with the positioning groove 1141. The positioning hole 1142 and the threaded hole 1121 are arranged opposite to each other. The fastener is threaded into the threaded hole 1121 through the positioning hole 1142. This not only makes the drive cylinder 114 more securely fixed to the second end of the mounting tube 112, but also greatly reduces the difficulty of installation and disassembly between the drive cylinder 114 and the mounting tube 112. This greatly improves the maintenance convenience and usage stability of the cleaning and straightening equipment for aluminum lens barrels of automotive lenses.

[0047] In one embodiment, the cold drawing straightening assembly includes a straightening die (not shown), a supporting inner die head (not shown), and a drawing clamp (not shown). The straightening die has a straightening hole (not shown). The supporting inner die head is adapted to fit the cavity of the aluminum lens barrel blank and extends into the cavity and abuts against the inner circumferential wall of the cavity. The drawing clamp is used to clamp and fix the constricted end of the aluminum lens barrel blank and drag the aluminum lens barrel blank through the straightening hole to perform a straightening operation on the aluminum lens barrel blank. This allows the supporting inner die head and the hole wall of the straightening hole to work together, which not only straightens the aluminum lens barrel blank and ensures its straightness, but also prevents the aluminum lens barrel blank from deforming due to pressure when passing through the straightening hole, thereby greatly improving the production quality of the aluminum lens barrel.

[0048] It should be noted that the pulling clamp is existing technology and will not be described in detail here.

[0049] like Figures 4 to 8 As shown, this disclosure also provides a method for cleaning and straightening an aluminum lens barrel for automotive lenses, including the cleaning and straightening equipment for an aluminum lens barrel for automotive lenses described in any of the above embodiments; the method for cleaning and straightening an aluminum lens barrel for automotive lenses includes some or all of the following steps: S10: Obtain the aluminum lens barrel blank after the necking operation is completed, and fix it. S20, the mounting end of the connecting rod 110 is inserted into the cavity of the aluminum lens barrel blank and moved toward the constricted end of the aluminum lens barrel blank until the connecting rod 110 abuts against the constricted end of the aluminum lens barrel blank, so as to drive the airbag end of the airbag component 120 to the preset position of the cavity. The mounting end of the connecting rod 110 is inserted into the cavity of the aluminum lens barrel blank and moved toward the constricted end of the aluminum lens barrel blank until the connecting rod 110 abuts against the constricted end of the aluminum lens barrel blank, so as to drive the airbag end of the airbag component 120 to the preset position in the cavity, so that the cleaning component 10 can effectively clean the aluminum shavings and burrs in the cavity.

[0050] S30, activate the airbag component 120 to inflate the airbag end of the airbag component 120 until it presses against the inner circumferential wall of the cylinder cavity. In this embodiment, the airbag component 120 is activated to inflate its airbag end until it presses against the inner circumferential wall of the cylinder cavity. This allows the airbag end of the airbag component 120 to slide relative to the inner circumferential wall of the cylinder cavity, scraping away aluminum shavings and burrs adhering to the inner circumferential wall. Compared to the manual handheld air blowing cleaning method in the aforementioned related technologies, the cleaning and straightening equipment for aluminum lens barrels of automotive lenses disclosed in this invention can not only effectively clean aluminum shavings and burrs on the inner wall of the cylinder cavity, thus avoiding the risk of scratches on the inner wall of the aluminum lens barrel blank due to aluminum shavings and burrs adhering to the inner wall during the cold drawing and straightening operation, but also effectively reduce the cleaning difficulty of the aluminum lens barrel blank. At the same time, the cleaning component 10 can also effectively extend into the cylinder cavity for cleaning, thereby greatly improving the cleaning effect and efficiency of the cleaning and straightening equipment for aluminum lens barrels of automotive lenses, and thus greatly improving the production quality and efficiency of aluminum lens barrels.

[0051] S40, pull the mounting end of the connecting rod 110 outward to drive the airbag end of the airbag component 120 to move away from the constricted end of the aluminum lens barrel blank until it is detached from the barrel cavity. In this embodiment, the mounting end of the connecting rod 110 is pulled outward to drive the airbag end of the airbag component 120 to move away from the constricted end of the aluminum lens barrel blank until it is detached from the cavity. This allows the airbag end of the airbag component 120 to carry out the aluminum shavings and burrs attached to the inner wall of the cavity, thereby enabling the cleaning component 10 to effectively remove the aluminum shavings and burrs in the cavity and improve the cleaning efficiency of the aluminum lens barrel blank.

[0052] S50 uses a cold-drawing and straightening assembly to perform cold-drawing and straightening operations on aluminum lens barrel blanks that have undergone cleaning.

[0053] In this embodiment, the aluminum lens barrel blank that has undergone cleaning is cold-drawn and straightened using a cold-drawing and straightening assembly to ensure the straightness of the aluminum lens barrel blank, thereby improving the production quality of the aluminum lens barrel.

[0054] In this embodiment, the cleaning and straightening method for the aluminum lens barrel of an automotive lens includes the following steps: First, an aluminum lens barrel blank after the necking operation is completed is obtained; then, the mounting end of the connecting rod 110 is inserted into the cavity of the aluminum lens barrel blank and moved towards the necking end of the aluminum lens barrel blank until the connecting rod 110 abuts against the necking end of the aluminum lens barrel blank, so as to drive the airbag end of the airbag component 120 to a preset position in the cavity; then, the airbag component 120 is activated to inflate the airbag end of the airbag component 120 until it is interference-fitted against the inner peripheral wall of the cavity; then, the connecting rod 110 is pulled outward to drive the airbag end of the airbag component 120 to move away from the necking end of the aluminum lens barrel blank until it is detached from the cavity; finally, the aluminum lens barrel blank after the cleaning operation is performed by a cold drawing straightening assembly.

[0055] In one embodiment, the connecting rod 110 includes an mounting tube 112, a telescopic part 113, and a driving cylinder 114. The first end of the mounting tube 112 is sleeved on the first end of the telescopic part 113, and the outer peripheral wall of the first end of the telescopic part 113 slides against the inner peripheral wall of the mounting tube 112. The fixed end of the driving cylinder 114 is installed and fixedly fixed to the second end of the mounting tube 112. The driving end of the driving cylinder 114 is disposed inside the mounting tube 112 and is fixedly connected to the end of the first end of the telescopic part 113. The driving end of the driving cylinder 114 is used to drive the telescopic part 113 to slide relative to the mounting tube 112. The airbag end of the airbag component 120 is disposed at the second end of the telescopic part 113. Step S20, in which the mounting end of the connecting rod 110 is inserted into the cavity of the aluminum lens barrel blank and moved toward the constricted end of the aluminum lens barrel blank until the connecting rod 110 abuts against the constricted end of the aluminum lens barrel blank, thereby driving the airbag end of the airbag component 120 to a preset position in the cavity, includes some or all of the following steps: S21, align the second end of the telescopic part 113 with the opening of the cylinder cavity away from the constricted end of the aluminum mirror tube blank; S22, the telescopic part 113 is driven by the drive cylinder 114 to extend into the cylinder cavity and move toward the constricted end of the aluminum lens barrel blank until the end of the second end of the telescopic part 113 abuts against the constricted end of the aluminum lens barrel blank.

[0056] In this embodiment, the telescopic part 113 is driven by the drive cylinder 114 to extend into the cylinder cavity and move towards the constricted end of the aluminum lens barrel blank until the end of the second end of the telescopic part 113 abuts against the constricted end of the aluminum lens barrel blank. This allows the telescopic part 113 to drive the airbag end of the airbag component 120 to extend into the preset position of the cylinder cavity. This not only greatly improves the automation level of the cleaning component 10, but also enables the cleaning component 10 to effectively extend into the inside of the cylinder cavity for cleaning operations, thereby greatly improving the cleaning effect and ease of use of the cleaning component 10.

[0057] In one embodiment, the step of pulling the mounting end of the connecting rod 110 outward to move the airbag end of the airbag component 120 away from the constricted end of the aluminum lens barrel blank until it detaches from the barrel cavity includes part or all of the following step S40: S41, the second end of the telescopic part 113 is driven by the drive cylinder 114 to move away from the constricted end of the aluminum mirror barrel blank until it returns to the initial position, so that the second end of the telescopic part 113 drives the airbag end of the airbag component 120 to disengage from the barrel cavity. In this embodiment, the second end of the telescopic part 113 is driven by the driving cylinder 114 to move away from the constricted end of the aluminum lens barrel blank until it returns to the initial position, so that the second end of the telescopic part 113 drives the airbag end of the airbag component 120 to disengage from the cylinder cavity, so that the airbag end of the airbag component 120 scrapes off the aluminum shavings and burrs on the inner wall of the cylinder cavity and carries them out of the cylinder cavity, thereby greatly improving the ease of use of the cleaning component 10.

[0058] S42, close the airbag component 120 and remove aluminum shavings and burrs from the airbag end surface of the airbag component 120.

[0059] In this embodiment, the airbag component 120 is closed, and aluminum shavings and burrs on the surface of the airbag end of the airbag component 120 are removed to avoid reducing the cleaning effect of the aluminum lens barrel blank due to the presence of some aluminum shavings and burrs on the airbag end of the airbag component 120 during the next use.

[0060] In one embodiment, when cleaning the aluminum lens barrel blank, the aluminum lens barrel blank is positioned horizontally or with its constricted end facing upwards. This prevents some of the aluminum chips and burrs on the surface of the airbag end of the airbag component 120 from falling back into the barrel cavity due to gravity when the airbag end of the airbag component 120 carries out aluminum chips and burrs, thereby effectively improving the cleaning effect of the aluminum lens barrel blank.

[0061] Compared with the prior art, this disclosure has at least the following advantages: The above-mentioned cleaning and straightening method for the aluminum lens barrel of an automotive lens includes the following steps: First, obtain the aluminum lens barrel blank after the necking operation is completed; then, insert the mounting end of the connecting rod 110 into the cavity of the aluminum lens barrel blank and move it towards the necked end of the aluminum lens barrel blank until the connecting rod 110 abuts against the necked end of the aluminum lens barrel blank, so as to drive the airbag end of the airbag component 120 to a preset position in the cavity; then, activate the airbag component 120 to inflate the airbag end of the airbag component 120 until it exceeds the tolerance. The connecting rod 110 is attached to the inner circumferential wall of the cylinder cavity; then, the connecting rod 110 is pulled outward to move the airbag end of the airbag component 120 away from the constricted end of the aluminum lens barrel blank until it is detached from the cylinder cavity; finally, the aluminum lens barrel blank that has completed the cleaning operation is cold-drawn and straightened by the cold drawing and straightening assembly. When it is necessary to clean the aluminum chips and burrs on the cylinder cavity of the aluminum lens barrel blank, it is only necessary to first insert the mounting end of the connecting rod 110 into the cylinder cavity of the aluminum lens barrel blank to move the airbag end of the airbag component 120 into the pre-cut end of the cylinder cavity. The airbag component 120 is positioned and then activated, causing its airbag end to inflate. This allows the airbag end of the airbag component 120 to press against the inner circumferential wall of the aluminum lens barrel blank. Finally, the mounting end of the connecting rod 110 is pulled out of the cavity away from the constricted end of the aluminum lens barrel blank. This allows the airbag end of the airbag component 120 to remove aluminum shavings and burrs from the inner circumferential wall of the aluminum lens barrel blank from the cavity. Compared to the manual handheld air blowing cleaning method in the aforementioned related technologies, the cleaning and straightening method for aluminum lens barrels of automotive lenses disclosed in this invention... The equipment can effectively clean aluminum shavings and burrs on the inner wall of the cylinder, thus avoiding the risk of scratches on the inner wall of the aluminum lens barrel blank due to the adhesion of aluminum shavings and burrs during the cold drawing and straightening operation. It can also effectively reduce the cleaning difficulty of the aluminum lens barrel blank. At the same time, the cleaning component 10 can effectively extend into the inside of the cylinder for cleaning, thereby greatly improving the cleaning effect and efficiency of the cleaning and straightening equipment for automotive lens aluminum barrels, and thus greatly improving the production quality and efficiency of aluminum lens barrels.

[0062] 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 disclosed 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.
