Description

Technical Field

[0001] This application relates to the field of automotive lamp cover spraying technology, specifically an automotive lamp cover spraying device. Background Technology

[0002] In the automotive lighting manufacturing industry, the painting of the headlight cover is a crucial process. As a key component of the headlight, the headlight cover not only affects the aesthetic appearance of the headlight but also directly relates to its lighting performance and driving safety.

[0003] Chinese utility model patent CN221772608U discloses a surface spraying device for producing automotive lamp housings. By incorporating a bonding block that moves to conform to the lamp surface, the spray nozzle can perform comprehensive and uniform spraying, resulting in good coating effects. However, in actual painting operations, the sprayed material often scatters and adheres to surrounding areas. This leads to material easily falling onto the lamp housing from unpainted or unpainted components or other parts, contaminating the lamp housing surface and affecting product quality and yield.

[0004] Therefore, this application provides a vehicle headlight cover spraying device to solve the above problems. Utility Model Content

[0005] This application provides a vehicle headlight cover spraying device, which aims to solve the problems mentioned in the background art, such as the existing spraying devices having good spraying effect but having material scattering that causes vehicle headlight cover contamination, affecting product quality and pass rate.

[0006] To achieve the above objectives, this application provides the following technical solution: a vehicle headlight cover painting device, including a housing, a support base fixedly installed in the housing for supporting the vehicle headlight cover, a painting component installed in the housing at a position corresponding to the position above the support base, and a lifting component installed at the top of the housing and connected to the painting component for moving the painting component closer to or away from the support base.

[0007] The spraying device also includes a baffle rotatably disposed within the housing and located between the paint spraying assembly and the support base for blocking material from the headlight cover on the support base, and a transmission assembly disposed inside the housing and connected to the baffle and the lifting assembly for transmitting power from the lifting assembly to the baffle, causing the baffle to flip. The baffle effectively prevents material from the paint spraying assembly or other parts from falling onto the headlight cover before or after spraying, thus avoiding contamination and damage, and ensuring the stability and consistency of the spraying quality. Simultaneously, the transmission assembly design allows the baffle to automatically flip as driven by the lifting assembly. During spraying, the baffle flips to a vertical position, not obstructing the work of the paint spraying assembly; while before or after spraying, the baffle flips to a horizontal position to block material. This design greatly enhances the flexibility and convenience of operation.

[0008] Preferably, in order to achieve the lifting and lowering of the painting component, the lifting component includes a connecting column disposed inside the chassis at a position corresponding to the position above the painting component, and a servo electric cylinder fixedly disposed at the top of the chassis and connected to the top of the lifting component for raising and lowering the connecting column; using the servo electric cylinder as a power source, the lifting height and speed of the connecting column can be precisely controlled, thereby achieving precise positioning of the painting height of the painting component.

[0009] Preferably, in order to achieve the spraying operation, the spraying assembly includes a rotating seat rotatably connected to the bottom end of the connecting column, a motor fixedly disposed in the connecting column for driving the rotating seat to rotate, a mounting bracket fixedly installed at the bottom end of the rotating seat, and a spray head fixedly installed on the mounting bracket; the combined use of the rotating seat and the motor allows the spray head to rotate around the connecting column, thereby expanding the spraying range and improving the spraying uniformity.

[0010] Preferably, to achieve synchronous flipping of the baffle, the transmission assembly includes a fixed frame fixedly disposed inside the housing on the side away from the support base and located on the side of the baffle; a receiving cavity opened in the fixed frame; a toothed plate longitudinally penetrating the receiving cavity and slidably connected to the fixed frame; a connecting frame fixedly disposed on the top of the toothed plate and fixedly connected to one side of the connecting column; a gear disposed in the receiving cavity and meshing with the toothed plate; a transmission shaft transversely penetrating the fixed frame and the gear and fixedly connected to the gear; and a bracket disposed outside the fixed frame and fixedly connected at both ends to the transmission shaft and the baffle, respectively. The transmission shaft is rotatably connected to the fixed frame. Through the combined design of the toothed plate, the gear, the transmission shaft, and the bracket, the baffle can be synchronously flipped with the lifting assembly, simplifying the operation process and improving the degree of automation.

[0011] Preferably, to ensure the stability of the toothed plate movement, the transmission assembly further includes a guide rod that runs longitudinally through the receiving cavity and the side of the toothed plate away from the gear, with both ends fixedly connected to the inside of the receiving cavity and the top of the inside of the housing, respectively. The toothed plate is slidably connected to the guide rod. The guide rod provides a stable movement path for the toothed plate, limiting the lateral swaying of the toothed plate during movement. This limitation ensures that the toothed plate can move smoothly and stably along a predetermined straight trajectory, thereby avoiding transmission failures caused by swaying or deviation.

[0012] Preferably, in order to further improve the quality of the spraying, the baffle is provided with a blower assembly for blowing away dust or drying the headlight cover on the support seat; the design of the blower assembly can blow away dust or dry the headlight cover before and after spraying, effectively removing dust and moisture from the surface of the cover, and improving the spraying quality and adhesion.

[0013] Preferably, in order to achieve dust blowing or air drying, the blowing assembly includes a pipe that passes through the baffle and is fixedly connected to the baffle, and a fan that is fixedly installed on the top of the outside of the chassis and communicates with the end of the pipe away from the baffle; the combined design of the pipe and the fan makes the blowing operation simple.

[0014] The headlight cover painting device, through the baffle, can effectively prevent materials from the paint components or other parts from falling onto the headlight cover before or after painting, thereby avoiding contamination and damage, and ensuring the stability and consistency of the painting quality.

[0015] The headlight cover painting device is equipped with a transmission component, which allows the baffle to automatically flip as driven by the lifting component. During the painting operation, the baffle flips to a vertical position, which does not hinder the operation of the painting component. When not painting or after painting is completed, the baffle flips to a horizontal position to block the material. This design greatly enhances the flexibility and convenience of operation.

[0016] This headlight cover spraying device, by setting a blowing component on the baffle, can blow away dust or air dry the headlight cover before and after spraying, effectively removing dust and moisture from the surface of the cover, and further improving the spraying quality and adhesion.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example 1

[0031] This embodiment provides a vehicle headlight cover spraying device, such as... Figures 1-3 As shown, the painting device includes a housing 1, a support base 2 fixedly installed inside the housing 1 for supporting the headlight cover, a painting assembly 3 installed inside the housing 1 at a position above the support base 2, and a lifting assembly 4 installed at the top inside the housing 1 and connected to the painting assembly 3 for moving the painting assembly 3 closer to or away from the support base 2; the painting device also includes a baffle 5 rotatably installed inside the housing 1 and located between the painting assembly 3 and the support base 2 for blocking the headlight cover on the support base 2, and a transmission assembly 6 installed inside the housing 1 and connected to the baffle 5 and the lifting assembly 4 for transmitting power from the lifting assembly 4 to the baffle 5, causing the baffle 5 to flip.

[0032] In use, before the painting operation, the headlight cover to be painted is placed on the support base 2. At this time, the baffle 5 is in a horizontal state and is placed between the paint spraying assembly 3 and the support base 2 to prevent materials from the paint spraying assembly 3 or other locations from falling onto the headlight cover to be painted. Next, the lifting assembly 4 is activated to drive the paint spraying assembly 3 to move closer to the headlight cover to be painted on the support base 2. Due to the transmission action of the transmission assembly 6, the drive of the paint spraying assembly 3 will synchronously drive the baffle 5 to flip to a vertical state to avoid interfering with the painting. Immediately afterwards, the paint spraying assembly 3 is activated to start painting the headlight cover placed on the support base 2. After the painting is completed, the painting of the paint spraying assembly 3 is paused, and the lifting assembly 4 is activated to drive the paint spraying assembly 3 to move away from the painted headlight cover. At this time, also through the transmission of the transmission assembly 6, the baffle 5 will automatically flip from a vertical state to a horizontal state and be placed on the painted headlight cover to prevent materials from the paint spraying assembly 3 or other locations from falling onto the headlight cover and affecting the painting quality.

[0033] Specifically, the lifting assembly 4 includes a connecting column 41 located inside the chassis 1 above the painting assembly 3, and a servo electric cylinder 42 fixedly located at the top of the chassis 1 and connected to the top of the lifting assembly 4 for raising and lowering the connecting column 41.

[0034] When the paint spraying assembly 3 needs to move closer to or away from the headlight cover, the servo cylinder 42 is activated. At this time, the piston rod of the servo cylinder 42 begins to extend and retract. As the piston rod extends and retracts, the connecting column 41 connected to it will also move up and down in the vertical direction accordingly. Thus, the raising and lowering of the connecting column 41 can drive the paint spraying assembly 3 connected to it to rise and fall together, thereby realizing the adjustment of the height of the paint spraying assembly 3 so that the paint spraying assembly 3 can move closer to the headlight cover for painting or move away from the headlight cover to pause the painting operation.

[0035] Furthermore, the painting assembly 3 includes a rotating seat 31 rotatably connected to the bottom end of the connecting column 41, a motor fixedly installed in the connecting column 41 for driving the rotating seat 31 to rotate, a mounting bracket 32 ​​fixedly installed at the bottom end of the rotating seat 31, and a spray head 33 fixedly installed on the mounting bracket 32.

[0036] When painting is required, the lifting assembly 4 drives the painting assembly 3 to move closer to the headlight cover to be painted on the support base 2. Then, the motor is started. At this time, the motor drives the rotating base 31 to rotate. Since the mounting bracket 32 ​​is connected to the rotating base 31 and the nozzle 33 is mounted on the mounting bracket 32, the rotation of the rotating base 31 will synchronously drive the mounting bracket 32 ​​and the nozzle 33 to rotate. Thus, while rotating, the nozzle 33 starts to spray paint, and the headlight cover on the support base 2 can be painted. When the painting is completed, the nozzle 33 and the motor are paused.

[0037] Furthermore, the transmission assembly 6 includes a fixed frame 61 fixedly disposed in the housing 1 on the side away from the support base 2 and on the side of the baffle 5, a receiving cavity 62 opened in the fixed frame 61, a toothed plate 64 longitudinally penetrating the receiving cavity 62 and slidably connected to the fixed frame 61, a connecting frame 63 fixedly disposed at the top of the toothed plate 64 and fixedly connected to the side of the connecting column 41, a gear 65 disposed in the receiving cavity 62 and meshing with the toothed plate 64, a transmission shaft 66 transversely penetrating the fixed frame 61 and the gear 65 and fixedly connected to the gear 65, and a bracket 67 disposed on the outside of the fixed frame 61 and fixedly connected at both ends to the transmission shaft 66 and the baffle 5 respectively, with the transmission shaft 66 rotatably connected to the fixed frame 61;

[0038] When the servo cylinder 42 drives the connecting column 41 to descend, and simultaneously moves the painting assembly 3 closer to the headlight cover to be painted on the support 2, since the connecting column 41 is connected to the connecting bracket 63, and the connecting bracket 63 is connected to the gear plate 64, the gear plate 64 will also descend synchronously in the receiving cavity 62 as the connecting column 41 descends. Since the gear 65 connected to the drive shaft 66 meshes with the gear plate 64, the gear 65 and the drive shaft 66 will rotate a certain number of times as the gear plate 64 descends. Then, the drive shaft 66, through the connection of the bracket 67, will synchronously drive the baffle 5 to flip, causing the horizontal baffle 5 to flip to a vertical position. To avoid affecting the painting of the headlight cover by the painting assembly 3, the connecting column 41 is raised when the servo cylinder 42 drives the connecting column 41 to rise, and simultaneously moves the painting assembly 3 away from the headlight cover. The connecting bracket 63 and the gear plate 64 will also rise simultaneously. Therefore, as the gear plate 64 rises, the gear 65 and the drive shaft 66 will also rotate a certain number of times, and drive the baffle 5 connected to the bracket 67 to rotate from the vertical state to the horizontal state and be placed between the support base 2 and the painting assembly 3. This allows the baffle 5 to cover the painted or unpainted headlight cover, reducing the amount of material from the painting assembly 3 or other locations falling onto the headlight cover and affecting the painting quality.

[0039] To ensure the stability of the movement of the toothed plate 64, the transmission assembly 6 also includes a guide rod 68 that runs longitudinally through the receiving cavity 62 and the side of the toothed plate 64 away from the gear 65, with both ends fixedly connected to the inside of the receiving cavity 62 and the top of the inside of the housing 1, respectively. The toothed plate 64 is slidably connected to the guide rod 68. The guide rod 68 provides a stable movement path for the toothed plate 64, limiting the lateral sway of the toothed plate 64 during movement. This limitation ensures that the toothed plate 64 can move smoothly and stably along a predetermined straight trajectory, thereby avoiding transmission failures caused by swaying or deviation.

[0040] Example 2

[0041] Unlike Example 1, as Figure 4As shown, in order to further improve the quality of spraying, the baffle 5 is provided with a blower assembly 7 for blowing dust or drying the headlight cover on the support 2. The blower assembly 7 includes a pipe 71 that passes through the baffle 5 and is fixedly connected to the baffle 5, and a fan 72 that is fixedly installed on the top of the outside of the housing 1 and connected to the end of the pipe 71 away from the baffle 5.

[0042] When the baffle 5 is in a horizontal state, the fan 72 can be started. At this time, the fan 72 starts to generate airflow and blows the airflow through the pipe 71 onto the support 2 for the headlight cover to be sprayed or after spraying. When the airflow blows onto the headlight cover to be sprayed, it can remove dust and impurities on the cover, thus playing the role of blowing away dust. When it blows onto the headlight cover after spraying, the airflow can also accelerate its evaporation and drying process, thus playing the role of air drying.

[0043] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
