Technical Field
[0001] This application relates to the field of automotive lighting reuse, and in particular to a remanufacturing device for a three-in-one assembly of automotive headlights. Background Technology
[0002] Automotive headlights, primarily referring to combination headlights that integrate low beams, high beams, parking lights, and turn signals into a single unit, often exhibit issues like degreasing, yellowing, and cracking with vehicle use. They can even be damaged in accidents, leading to decreased light intensity, impaired driver visibility, and safety hazards. Current technology for repairing damaged headlights typically involves direct replacement, resulting in the underutilization and waste of these old lights.
[0003] The remanufacturing of used car lights requires three processes: dust removal, flame treatment, and adhesive application. Currently, each process is carried out at a separate workstation with spacing between adjacent workstations. In actual processing, cleaning, dust removal of the headlight cover, flame treatment, and finally adhesive application are required in sequence. Although the above processes can be automated with the help of robotic arms, there are still problems of low processing efficiency and high equipment setup costs. Summary of the Invention
[0004] To address the issues of high cost and low processing efficiency in the remanufacturing and assembly of waste automotive headlights, this application provides a three-in-one assembly processing device for remanufacturing automotive headlights.
[0005] The technical solution of the remanufacturing automotive headlight three-in-one assembly processing device provided in this application is as follows:
[0006] A remanufacturing automotive headlight three-in-one assembly processing device includes an operating table, a clamp disposed on the operating table for holding the headlight, a robotic arm, a dust removal mechanism, a flame gun, and a glue gun. The output end of the robotic arm is equipped with a mounting base, and a rotating seat and a rotation drive for driving the rotating seat to rotate are rotatably mounted on the mounting base. The dust removal mechanism, the flame gun, and the glue gun are all mounted on the rotating seat.
[0007] The flame gun and the glue gun are mounted on the same side of the rotating base and are spaced apart; the dust removal mechanism is mounted on the other side of the rotating base.
[0008] The rotating base is provided with a heat insulation mechanism for separating the flame gun and the glue gun. The flame gun is located in front of the glue gun in the direction of travel. The rotating base is provided with a correction mechanism for correcting the trajectory of the flame gun to ensure that the projection of the flame gun on the headlight cover always falls on the glue application outline of the headlight cover.
[0009] By adopting the above technical solution, when remanufacturing automotive headlights, the headlight housing to be processed is first fixed to the operating table using a fixture. Then, a rotating drive unit drives the rotating seat to align the dust removal mechanism with the headlight housing. The robotic arm drives the mounting base to move along the outline of the headlight housing to be glued, and the dust removal mechanism can clean the part of the headlight housing to be glued. After cleaning, the rotating drive unit continues to drive the rotating seat to align the glue gun with the outline of the headlight housing to be glued. Subsequently, the correction mechanism corrects the position of the flame gun on the rotating seat so that the flame sprayed by the flame gun falls on the outline of the headlight housing to be glued. In this way, when the robotic arm drives the mounting base to move along the outline of the headlight housing to be glued, the correction mechanism corrects the position of the flame gun in real time. This allows the flame gun to first heat the part of the headlight housing to be glued, and then the glue gun located behind it applies glue to the heated part. This effectively ensures that the glue does not easily detach from the headlight housing, ensuring the quality of the glue application.
[0010] This setup integrates the dust removal, flame treatment, and adhesive application processes into a single robotic arm, performing them in two separate operations. This significantly reduces the setup cost of processing equipment and improves the efficiency of reusing automotive lamps. Furthermore, applying adhesive immediately after flame treatment fully utilizes the heated headlight housing, enhancing the bonding strength between the adhesive and the housing. Since the headlight housing has an irregular curved surface, the robotic arm can only ensure the adhesive gun travels along this contour. The gap between the flame gun nozzle and the adhesive gun nozzle causes a significant deviation. A correction mechanism can adjust the flame gun position in real time, ensuring a high-precision and efficient connection between the flame treatment and adhesive application processes. Additionally, the heat insulation mechanism significantly reduces the impact of the flame from the flame gun on the viscosity of the adhesive at the adhesive gun nozzle, minimizing excessive moisture evaporation and ensuring adhesive quality.
[0011] Optionally, the flame gun is equipped with an image sensor for capturing the outline of the headlight cover being coated with adhesive. The image sensor is electrically connected to a controller, and the controller is electrically connected to the correction mechanism.
[0012] The controller is configured to determine the offset of the flame gun based on the distance between the projection points of the image sensor and the flame gun on the headlight housing and the glue application profile, and to activate the correction mechanism.
[0013] By adopting the above technical solution, the image sensor captures images of the flame gun nozzle and the adhesive application contour on the headlight cover in real time from the perspective of the flame gun spraying flame. The controller determines the amount of correction required for the flame gun based on the position of the flame gun spray point and the local adhesive application contour, and then controls the correction mechanism to correct the flame gun to the adhesive application contour in real time, ensuring the real-time and accurate operation of the flame treatment process.
[0014] Optionally, the correction mechanism includes a correction seat rotatably mounted on the rotating seat and a rotary drive for driving the correction seat to rotate on the rotating seat. The glue gun is located on the rotation axis of the correction seat, the flame gun is located on the movable end of the correction seat, and the rotary drive is electrically connected to the controller.
[0015] By adopting the above technical solution, the controller calculates the offset of the flame gun and controls the rotary drive to work. The rotary drive drives the correction seat to rotate on the rotating seat, so that the flame gun on the rotating seat moves to the glue application contour, thus realizing automatic real-time correction of the flame gun.
[0016] Optionally, the correction mechanism includes a slide rail whose length direction is orthogonal to the arrangement direction of the flame gun and the glue gun on the rotating base. The slide rail is fixed to the rotating base, and a slide block is slidably disposed on the slide rail. The flame gun is mounted on the slide block.
[0017] The rotating base is equipped with a linear drive unit for driving the slide block to slide on the slide rail, and the linear drive unit is electrically connected to the controller.
[0018] By adopting the above technical solution, the controller calculates the offset of the flame gun and then controls the linear drive to work. The linear drive drives the slide block to slide on the slide rail so that the flame gun moves to the position corresponding to the glue application contour.
[0019] Optionally, the heat insulation mechanism includes a heat insulation plate disposed between the flame gun and the nozzle of the glue gun, and the heat insulation plate is also provided with a circulating cooling system.
[0020] By adopting the above technical solution, the heat insulation plate can insulate the flame emitted by the flame gun during operation, thereby reducing the impact of the high temperature of the flame on the moisture content of the glue in the caulking gun. Furthermore, by setting a circulating cooling system on the heat insulation plate, the heat insulation effect of the heat insulation plate can be further improved, thereby reducing the impact of the high temperature gas around the flame on the glue in the caulking gun.
[0021] Optionally, the heat insulation plate is arranged around the flame gun.
[0022] By adopting the above technical solution, the heat insulation plate set around the flame gun can increase the heat insulation area between the flame gun and the glue gun, thereby increasing the heat insulation effect.
[0023] Optionally, the dust removal mechanism includes a dust extraction pipe connected to the dust collector's exhaust port, the dust extraction pipe having a telescopic tube flexibly connected to its opening, and a dust extraction hole being formed through the periphery of the telescopic tube.
[0024] By adopting the above technical solution, when the robot arm moves the mounting base, the telescopic tube on the dust extraction pipe comes into contact with the area of the headlight cover to be sealed. After the external dust collector is turned on, the dust extraction pipe sucks the dust from the sealing area through the opening at the end of the telescopic tube, and also sucks the dust from the sealing area through multiple dust extraction holes around the telescopic tube. This allows for the effective cleaning of the sealing area of the headlight cover as comprehensively as possible.
[0025] Optionally, a cleaning ring coaxially mounted on one end of the dust extraction pipe near the telescopic pipe is circumferentially rotatable. Bristles are mounted on the side of the cleaning ring opposite to the dust extraction pipe. A drive assembly is provided on the dust extraction pipe to drive the cleaning ring to rotate on the dust extraction pipe.
[0026] By adopting the above technical solution, when the dust extraction pipe is sucking up dust, the driving component drives the cleaning ring to rotate on the dust extraction pipe, so that the bristles on the cleaning ring can clean the area of the headlight cover to be glued. This can effectively remove dust and debris stuck to the headlight cover to a certain extent, thereby promoting the dust extraction effect of the dust extraction pipe. In addition, the soft bristles are easier to embed into the gaps of the headlight cover or the corners of the glue application groove, thereby improving the cleaning quality.
[0027] Optionally, the end of the telescopic tube is provided with an inward rolled edge.
[0028] By adopting the above technical solution, the inward rolling edge setting can reduce the scratches caused to the headlight cover when the telescopic tube touches and moves.
[0029] Optionally, a pressure sensor is provided between the dust extraction pipe and the telescopic pipe, and the pressure sensor is controlled and connected to the drive assembly; when the telescopic pipe is retracted into the dust extraction pipe, the pressure sensor is abutted.
[0030] By adopting the above technical solution, when the telescopic tube comes into contact with the area to be glued on the headlight cover, the pressure sensor is pressed, and the drive component is controlled to drive the cleaning ring to drive the bristles to clean the area to be glued, thus realizing the automatic cleaning of the area to be glued by the cleaning ring; at the same time, the rotation state of the cleaning ring can also be used to intuitively determine whether the telescopic tube is in contact with the headlight cover.
[0031] In summary, this application includes at least one of the following beneficial technical effects:
[0032] 1. Integrating dust removal, flame treatment, and adhesive application into a single robotic arm for two separate operations significantly reduces equipment setup costs and improves the efficiency of remanufacturing automotive headlights. Applying adhesive immediately after flame treatment fully utilizes the heated headlight housing, enhancing the bond strength between the adhesive and the housing. Furthermore, a correction mechanism allows for real-time adjustment of the flame gun position, ensuring a high-precision and efficient connection between the flame treatment and adhesive application processes. Additionally, a heat insulation mechanism significantly reduces the impact of the flame on the viscosity of the adhesive in the adhesive gun nozzle, minimizing excessive moisture evaporation and ensuring adhesive quality.
[0033] 2. The image sensor captures images of the flame gun nozzle and the adhesive application contour on the headlight cover in real time from the perspective of the flame gun spraying flame. The controller determines the amount of correction required for the flame gun based on the position of the flame gun spray point and the local adhesive application contour, and then controls the correction mechanism to correct the flame gun to the adhesive application contour in real time, ensuring the real-time and accurate operation of the flame treatment process.
[0034] 3. Installing a heat insulation plate between the flame gun and the glue gun can block the influence of the high temperature of the flame on the moisture content of the glue in the glue gun. A circulating cooling system is installed on the heat insulation plate to further reduce the influence of the high temperature gas around the flame on the quality of the glue in the glue gun.

[0039] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0040] This application discloses a remanufacturing apparatus for a three-in-one assembly of automotive headlights. (Refer to...) Figure 1 and Figure 2 A remanufacturing automotive headlight three-in-one assembly processing device includes an operating table 1, a clamp 11 mounted on the operating table 1 for holding the headlight, a robotic arm 2, a dust removal mechanism, a flame gun 3, and a glue gun 4, wherein the flame gun 3 is a plasma flame gun 3; the output end of the robotic arm 2 is equipped with a mounting base 21, and a rotating seat 22 and a rotation drive component 23 for driving the rotating seat 22 to rotate are rotatably mounted on the mounting base 21. The dust removal mechanism, the flame gun 3, and the glue gun 4 are all mounted on the rotating seat 22; wherein the rotation drive component 23 can be a rotary cylinder or a servo motor, which can drive the rotating seat 22 to rotate at a precise angle on the mounting base 21.
[0041] Specifically, refer to Figure 1 and Figure 2 The flame gun 3 and the glue gun 4 are installed on the same side of the rotating base 22 and are spaced apart. The dust removal mechanism is installed on the other side of the rotating base 22. In actual installation, the dust removal mechanism can be installed on the adjacent side of the glue gun 4 or on the opposite side of the glue gun 4. In order to facilitate the spatial structure of the glue gun 4 and the flame gun 3, and to facilitate the precise switching between the dust removal process and the glue application process, in this embodiment, the dust removal mechanism is installed on the opposite side of the glue gun 4.
[0042] Furthermore, the rotating base 22 is provided with a heat insulation mechanism for separating the flame gun 3 and the glue gun 4. The flame gun 3 is located in front of the glue gun 4 in the direction of travel. The rotating base 22 is provided with a correction mechanism for correcting the trajectory of the flame gun 3 to ensure that the projection of the flame gun 3 on the headlight cover always falls on the glue application outline of the headlight cover.
[0043] In this way, when remanufacturing car headlights, the headlight cover to be processed is first fixed on the operating table 1 by the fixture 11. Then, the rotating drive 23 drives the rotating seat 22 to rotate until the dust removal component in the dust removal mechanism is aligned with the headlight cover. The robot arm 2 drives the mounting seat 21 to move along the outline of the headlight cover to be glued. The dust removal mechanism can clean the part of the headlight cover to be glued. After cleaning, the rotating drive 23 continues to drive the rotating seat 22 to rotate until the glue gun 4 is aligned with the outline of the headlight cover to be glued. Then, the correction mechanism corrects the position of the flame gun 3 on the rotating seat 22 so that the flame sprayed by the flame gun 3 falls on the outline of the headlight cover to be glued. In this way, when the robot arm 2 drives the mounting seat 21 to move along the outline of the headlight cover to be glued, the correction mechanism corrects the position of the flame gun 3 in real time. This allows the flame gun 3 to heat the part of the headlight cover to be glued first, and then the glue gun 4 located behind it applies glue to the heated part of the headlight cover. This can effectively ensure that the glue does not easily detach from the headlight cover and ensure the glue application quality.
[0044] Therefore, integrating the three processes of dust removal, flame treatment, and glue application into a single robotic arm 2 and performing them in two separate operations can significantly reduce the setup cost of processing equipment. Furthermore, applying the glue immediately after flame treatment fully utilizes the heating effect on the headlight cover, promoting stronger bonding between the glue and the cover. Since the headlight cover's contour to be glued is an irregular curved surface, the robotic arm 2 can only ensure that the glue gun 4 travels along this contour. However, a certain gap exists between the nozzles of the flame gun 3 and the glue gun 4, causing a significant deviation between the flame gun 3 nozzle and the contour. A correction mechanism can adjust the position of the flame gun 3 in real time, ensuring a high-precision and efficient connection between the flame treatment and glue application processes. Additionally, the heat insulation mechanism significantly reduces the impact of the flame from the flame gun 3 on the viscosity of the glue in the glue gun 4 nozzle, minimizing excessive moisture evaporation and ensuring optimal glue molding quality.
[0045] More specifically, refer to Figure 1 and Figure 2 The flame gun 3 is equipped with an image sensor 5 for capturing the adhesive application contour of the headlight housing. The image sensor 5 is electrically connected to a controller, which is also electrically connected to a correction mechanism. The controller is configured to calculate the offset of the flame gun 3 based on the distance between the projection points of the image sensor 5 and the flame gun 3 on the headlight housing and the adhesive application contour, and to activate the correction mechanism. For example, the imaging path of the image sensor 5 is set parallel to the flame path of the flame gun 3, and a calibration point is set at the focal point of the imaging area of the image sensor 5. The distance between the forming point on the headlight housing and the flame point of the flame gun 3 on the headlight housing is always constant. At the same time, the image sensor 5 also captures the local adhesive application contour within its field of view, mainly the adhesive application contour of the un-applied areas.
[0046] Therefore, when processing the image captured by the image sensor 5, the controller can directly identify or calculate the offset between the flame point of the flame gun 3 on the headlight cover and the adhesive application contour. It then controls the correction mechanism to change the position of the flame gun 3, ensuring that the flame point of the flame gun 3 on the headlight cover always falls on the adhesive application contour. This correction process is performed in real time. This ensures the accurate and smooth execution of both the flame treatment and adhesive application processes.
[0047] Considering that the robot arm 2 can always ensure that the flame gun 3 is in front of the travel path of the glue gun 4 while the mounting base 21 drives the glue gun 4 to move along the glue application contour of the headlight cover, so as to ensure the integrity of the glue application of the glue gun 4, the position of the flame gun 3 can be easily adjusted.
[0048] In one feasible embodiment, refer to Figure 3 The correction mechanism includes a correction seat 51 rotatably mounted on a rotating base 22 and a rotary drive 52 for driving the correction seat 51 to rotate on the rotating base 22. A glue gun 4 is located on the rotation axis of the correction seat 51, and a flame gun 3 is located on the movable end of the correction seat 51. The rotary drive 52 is electrically connected to a controller. The rotary drive 52 can be a rotary cylinder, a rotary electric cylinder, or a drive component that uses a servo motor to drive a gear set to rotate. In this embodiment, the rotary drive 52 is configured as a drive component that uses a servo motor to drive a gear set to rotate, which can achieve high-precision rotation of the correction seat 51.
[0049] In another feasible embodiment, refer to Figure 2 The correction mechanism includes a slide rail 53 whose length direction is orthogonal to the arrangement direction of the flame gun 3 and the glue gun 4 on the rotating base 22. The slide rail 53 is fixed to the rotating base 22, and a slide block 54 is slidably disposed on the slide rail 53. The flame gun 3 is mounted on the slide block 54, and the slide block 54 is anti-detached and slidably disposed on the slide rail 53, for example, the slide rail 53 is a T-shaped rail. A linear drive 55 for driving the slide block 54 to slide on the slide rail 53 is mounted on the rotating base 22. The linear drive 55 is electrically connected to the controller. The linear drive 55 can be a cylinder, an electric push rod, or a servo motor to drive the screw to rotate so that the slide block 54 moves. In this embodiment, the linear drive 55 is a screw threaded through the slide block 54 and a servo motor for driving the screw to rotate.
[0050] Since the flame gun 3 and the caulking gun 4 are integrated on the same side of the mounting base 21, and the flame treatment and caulking processes need to be performed synchronously in a sequential order, and the caulking profile of the headlight cover is an irregular curve, the flame gun 3 and the caulking gun 4 generally need to be placed close enough to reduce the amount of correction required by the flame gun 3, thereby reducing the difficulty of correction. However, this also means that the flame emitted by the flame gun 3 or the high temperature affected by the flame will affect the moisture content of the adhesive in the caulking gun 4, which may affect the viscosity of the sealant, or the continuous high heat may affect the quality of the sealant.
[0051] Therefore, refer to Figure 1 and Figure 2 The aforementioned heat insulation mechanism includes a heat insulation plate 6 disposed between the nozzles of the flame gun 3 and the caulking gun 4. The heat insulation plate 6 is also equipped with a circulating cooling system, and is arranged around the flame gun 3. Specifically, the heat insulation plate 6 is made of glass fiber, asbestos, rock wool, silicate, or new heat insulation materials such as aerogel felt or vacuum board. The circulating cooling system is primarily a water-cooled circulating system, which can be embedded in the heat insulation plate 6 or disposed on its side.
[0052] In this way, the heat insulation plate 6 can insulate the flame emitted by the flame gun 3 during operation, thereby reducing the impact of the high temperature of the flame on the moisture content of the glue in the caulking gun 4. Furthermore, the heat insulation effect of the heat insulation plate 6 can be further improved by setting a circulating cooling system on the heat insulation plate 6, thereby reducing the impact of the high temperature gas around the flame on the glue in the caulking gun 4. The heat insulation plate 6 arranged around the flame gun 3 can further increase the heat insulation area between the flame gun 3 and the caulking gun 4, thereby increasing the heat insulation effect.
[0053] Meanwhile, since the area of the headlight housing to be sealed with sealant is generally where the lamp housing is embedded, this sealing area is usually groove-shaped. Therefore, referring to... Figure 3 The aforementioned dust removal mechanism includes a dust extraction pipe 71 connected to the dust collector's exhaust port. A telescopic pipe 72 is elastically connected to the opening of the dust extraction pipe 71. Multiple dust extraction holes 73 are provided through the periphery of the telescopic pipe 72. The end of the telescopic pipe 72 has an inwardly rolled edge 77. Specifically, the telescopic pipe 72 is inserted into the opening of the dust extraction pipe 71, and both the dust extraction pipe 71 and the telescopic pipe 72 are fixedly connected to limit rings. A spring sleeved on the outer periphery of the telescopic pipe 72 is fixedly connected between the two limit rings. A cleaning ring 74 is rotatably mounted on the dust extraction pipe 71 near the end of the telescopic pipe 72, and is coaxial with it. The cleaning ring 74 can be rotatably mounted on the limit rings of the dust extraction pipe 71. Multiple bristles 75 are installed on the side of the cleaning ring 74 away from the dust extraction pipe 71. A drive assembly 76 is provided on the dust extraction pipe 71 to drive the cleaning ring 74 to rotate on the dust extraction pipe 71.
[0054] In this way, when the robotic arm 2 moves the mounting base 21, the telescopic tube 72 on the dust extraction pipe 71 comes into contact with the area of the headlight cover to be glued. After the external dust collector is turned on, the dust extraction pipe 71 sucks the dust from the glued area through the opening at the end of the telescopic tube 72, and also sucks the dust from the glued area through the multiple dust extraction holes 73 around the telescopic tube 72. This allows for a more comprehensive and effective cleaning of the glued area of the headlight cover. At the same time, the drive component 76 drives the cleaning ring 74 to rotate on the dust extraction pipe 71, so that the bristles 75 on the cleaning ring 74 clean the area of the headlight cover to be glued. This can effectively remove dust and debris adhering to the headlight cover to a certain extent, thereby promoting the dust extraction effect of the dust extraction pipe 71. Furthermore, the soft bristles 75 are easier to embed into the gaps of the headlight cover or the corners of the glued groove, thereby improving the cleaning quality.
[0055] To achieve the automatic cleaning effect of 75 bristles on the cleaning tube, refer to... Figure 3 A pressure sensor 78 is installed between the dust extraction pipe 71 and the telescopic pipe 72, and the pressure sensor 78 is controlled and connected to the drive assembly 76; when the telescopic pipe 72 is retracted into the dust extraction pipe 71, the pressure sensor 78 is abutted. Specifically, the drive assembly 76 consists of a gear ring coaxially fixed to the cleaning ring 74, a gear meshing with the gear ring, and a servo motor for driving the gear to rotate; the pressure sensor 78 is controlled and connected to the servo motor.
[0056] In this way, when the telescopic tube 72 comes into contact with the area of the headlight cover to be glued, the pressure sensor 78 is pressed, and the drive component 76 is controlled to drive the cleaning ring 74 to drive the bristles 75 to clean the area to be glued, thus realizing the automatic cleaning of the area to be glued by the cleaning ring 74; at the same time, the rotation state of the cleaning ring 74 can also be used to intuitively determine whether the telescopic tube 72 is in contact with the headlight cover, so as to ensure the effective cleaning effect of the dust extraction tube 71 on the headlight cover.
[0057] The implementation principle of the remanufacturing automotive headlight three-in-one assembly processing device in this application embodiment is as follows: The dust removal, flame treatment, and adhesive application processes are integrated into a single robotic arm 2 and performed in two separate operations. This significantly reduces the setup cost of processing equipment. Furthermore, adhesive application is performed immediately after flame treatment, fully utilizing the heated headlight housing to enhance the bonding strength between the adhesive and the housing. Since the headlight housing's adhesive-to-be-applied contour is an irregular curved surface, the robotic arm 2 can only ensure that the adhesive gun 4 travels along this contour. However, a certain distance exists between the nozzles of the flame gun 3 and the adhesive gun 4, causing a significant deviation between the flame gun 3 nozzle and the adhesive-to-be-applied contour. A correction mechanism can adjust the position of the flame gun 3 in real time, ensuring high precision and efficient connection between the flame treatment and adhesive application processes. Additionally, the heat insulation mechanism significantly reduces the impact of the flame from the flame gun 3 on the viscosity of the adhesive at the nozzle of the adhesive gun 4, minimizing excessive moisture evaporation from the adhesive and affecting the quality of the adhesive molding.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
