Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically a rapid spraying device for automobile bumpers. Background Technology

[0002] In the automotive manufacturing industry, bumpers, as key components for vehicle appearance and protection, directly impact the vehicle's visual appeal, weather resistance, and lifespan through their surface coating quality. As the automotive industry continuously raises demands for production efficiency and product quality, bumper coating processes are gradually evolving towards automation and precision. Currently, mainstream bumper coating processes typically include substrate pretreatment, surface cleaning, spraying, and curing. The spraying stage requires specialized equipment to achieve uniform paint coverage, ensuring consistent coating thickness and eliminating visual defects. To accommodate bumpers of different sizes and shapes, the spraying equipment often needs position adjustment capabilities for precise spraying of various areas of the bumper. Simultaneously, it requires corresponding auxiliary structures to ensure surface cleanliness before spraying, laying the foundation for high-quality subsequent coating. This utility model's rapid bumper spraying device is designed and developed based on this industry need.

[0003] In existing automotive bumper painting technology, although most devices have achieved automated painting and position adjustment, the bumper substrate is mostly made of polymer materials such as PP and ABS. During the initial injection molding and handling process, static electricity is easily generated due to friction. Static electricity will attract dust, fibers and other impurities from the surrounding environment. Currently, static electricity removal is mostly done in a one-time overall treatment before painting. However, when the bumper is transferred to the painting station, the surface is prone to friction with the conveyor belt and clamps, generating new static electricity and re-attracting impurities. If these impurities are not effectively removed, direct painting will lead to defects such as particles and pinholes in the coating. Utility Model Content

[0004] The purpose of this invention is to provide a rapid spraying device for automobile bumpers to solve the problem of electrostatic dust adsorption mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid spraying device for car bumpers includes a mounting box and a mounting frame, wherein auxiliary components are provided inside the mounting box;

[0007] The auxiliary component includes a rotating groove, inside which an annular component is rotatably disposed. A first annular groove is provided on the top of the annular component, and a second annular groove is provided above the first annular groove. A plasma fan is provided at the rear of the top of the mounting box, and an air outlet is provided on one side of the bottom of the annular component.

[0008] In a preferred embodiment of this utility model, a spray head is provided on the top of the inner side of the mounting box, the spraying direction of the spray head is downward, and a pipe is connected to the top of the spray head.

[0009] In a preferred embodiment of this utility model, an internally threaded sliding member is provided above the mounting box, and the internally threaded sliding member is slidably mounted on the inner side of the top of the mounting frame.

[0010] In a preferred embodiment of this utility model, a threaded rod is rotatably provided on the inner side of the top of the mounting bracket, and the threaded rod is threadedly connected to the internal threaded sliding member.

[0011] In a preferred embodiment of this utility model, a first motor is provided at the top front of the mounting bracket, and the output end of the first motor is connected to a threaded rod.

[0012] In a preferred embodiment of the present invention, the second annular groove is fixedly installed on the inner wall of the mounting box, the groove direction of the second annular groove is downward, and the second annular groove is connected to the first annular groove.

[0013] In a preferred embodiment of this utility model, the air outlet of the plasma fan is connected to and communicates with the second annular groove via a pipe, and the air outlet is connected to and communicates with the first annular groove.

[0014] In a preferred embodiment of this utility model, a second motor is provided at the front of the top of the mounting box, and a drive gear is provided on the bottom output end of the second motor. The drive gear is located inside the mounting box, and an internal gear is provided on the inner side of the annular component. The drive gear meshes with the internal gear.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: The second motor drives the drive gear to rotate, and through gear transmission, the annular component rotates, causing the air outlet to rotate to the front and rear of the nozzle. Before the nozzle sprays, a plasma fan blows air through the pipes, and the ionized air is transported through the second and first annular grooves, causing the ionized air to be blown out from the air outlet. This effectively neutralizes the static electricity generated on the bumper surface due to friction, preventing the static electricity from attracting dust, fibers, and other impurities. When the nozzle sprays forward, the air outlet rotates to the front of the nozzle, and when the nozzle sprays backward, the air outlet rotates to the rear of the nozzle, thus eliminating static electricity in the area before spraying. This ensures that each area to be sprayed undergoes immediate and precise static electricity removal before the paint is applied, reducing defects such as coating particles and pinholes caused by static electricity attracting impurities from the source.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figures 1-4 This utility model discloses a rapid spraying device for car bumpers, including a mounting box 1 and a mounting frame 2. Both the mounting box 1 and the mounting frame 2 are mounting structures used to install other structures. A nozzle 11 is provided on the top of the inner side of the mounting box 1. The spraying direction of the nozzle 11 is downward. A pipe is connected to the top of the nozzle 11. The pipe is a flexible hose. Its end is connected to a complete set of feeding devices, that is, feeding the nozzle 11, thereby spraying the car bumper. This is a conventional technical means for those skilled in the art.

[0026] An internally threaded sliding member 12 is provided on the top of the mounting box 1. The internally threaded sliding member 12 is slidably installed on the inner side of the top of the mounting frame 2. A threaded rod 21 is rotatably provided on the inner side of the top of the mounting frame 2. The threaded rod 21 is threadedly connected to the internally threaded sliding member 12. A first motor 22 is provided at the front of the top of the mounting frame 2. The first motor 22 is a servo motor and has a built-in braking structure. The output end of the first motor 22 is connected to the threaded rod 21. That is, the first motor 22 drives the threaded rod 21 to rotate. Through the threaded transmission, the internally threaded sliding member 12 drives the mounting box 1 and the spray head 11 to move back and forth, so that different positions of the car bumper are sprayed.

[0027] The mounting box 1 contains an auxiliary component, including a rotating groove 13, which is fixedly installed on the inner wall of the mounting box 1. An annular component 14 is rotatably mounted inside the rotating groove 13. A first annular groove 23 is located at the top of the annular component 14, and a second annular groove 32 is located above the first annular groove 23. The second annular groove 32 is fixedly installed on the inner wall of the mounting box 1. A plasma fan 3 is located at the rear top of the mounting box 1. An air outlet 24 is located on one side of the bottom of the annular component 14. The groove of the second annular groove 32 faces downwards and connects to the first annular groove 23. The air outlet of fan 3 is connected to the second annular groove 32 through a pipe, and the air outlet 24 is connected to the first annular groove 23. Before the nozzle 11 sprays, the plasma fan 3 blows air and the ion air is transported through the pipe and transmitted through the second annular groove 32 and the first annular groove 23, so that the ion air is blown out from the air outlet 24, thereby eliminating static electricity on the bottom of the car bumper. When the nozzle 11 sprays forward, the air outlet 24 rotates to the front of the nozzle 11, and when the nozzle 11 sprays backward, the air outlet 24 rotates to the rear of the nozzle 11.

[0028] A second motor 33 is installed at the top front of the mounting box 1. The second motor 33 is a servo motor with a built-in electromagnetic brake structure. A drive gear 34 is installed on the bottom output end of the second motor 33. The drive gear 34 is located inside the mounting box 1. An internal gear 31 is installed on the inner side of the ring part 14. The drive gear 34 meshes with the internal gear 31. That is, the second motor 33 drives the drive gear 34 to rotate, and then through gear transmission, the ring part 14 rotates, which makes the air outlet 24 rotate to the front and rear of the nozzle 11. The second motor 33 and the first motor 22 are connected to the same PLC controller for control. The controller model is Siemens S7-200 SMART CPU SR40, and it has been debugged in advance so that when the first motor 22 rotates forward and backward, the second motor 33 drives the air outlet 24 to rotate to the front and rear of the nozzle 11.

[0029] The working principle of this utility model is as follows: the car bumper is sprayed with paint through the nozzle 11. The first motor 22 drives the threaded rod 21 to rotate. Through threaded transmission, the internal threaded sliding part 12 drives the mounting box 1 and the nozzle 11 to move back and forth, so that different positions of the car bumper are sprayed. The second motor 33 drives the drive gear 34 to rotate. Through gear transmission, the annular part 14 rotates, so that the air outlet 24 rotates to the front and rear of the nozzle 11. Before the nozzle 11 sprays, the plasma fan 3 blows air and the ion air is transported through the pipe and transmitted through the second annular groove 32 and the first annular groove 23, so that the ion air is blown out from the air outlet 24, thereby eliminating static electricity at the bottom of the car bumper. When the nozzle 11 sprays forward, the air outlet 24 rotates to the front of the nozzle 11, and when the nozzle 11 sprays backward, the air outlet 24 rotates to the rear of the nozzle 11, thereby eliminating static electricity at the position before spraying.
