Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electrostatic dust removal devices, in particular to a surface cleaning device for automobile bumper processing. BACKGROUND

[0002] As an important part of the vehicle exterior, the automobile bumper is usually formed by engineering plastics (such as PP, ABS, etc.) through an injection molding process. During the processing, handling and storage, static charges are generated on the surface of the bumper due to friction, so that fine dust, fibers and particulate matters in the environment are easily adsorbed. Before entering the next process (such as spraying, electroplating), these contaminants must be thoroughly cleaned, otherwise the adhesion of the coating and the appearance quality of the final product will be seriously affected.

[0003] At present, for the surface cleaning of the automobile bumper, a common technical means such as the electrostatic dust removal device for the bumper disclosed in patent No. CN206897984U is to generate positive and negative ions by a built-in high-voltage generator rising to high-voltage corona air, then compress the air to blow out through small air flow holes to form an ion wind curtain covering the surface of the bumper product, so as to neutralize the positive and negative static charges on the surface of the bumper due to friction. The static electricity on the surface of the bumper is eliminated, and the ability to adsorb dust is lost, thereby achieving the dust removal effect.

[0004] It only sprays the ion wind curtain through the air outlet holes opened on the three fixed supports on the upper side and left and right sides. When processing the automobile bumper with complex curved surface characteristics, the core defect is that the ion wind curtain has insufficient uniformity and self-adaptive fitting ability to cover the surface of the workpiece. This directly leads to uneven cleaning effect, dead angle and other problems, and cannot meet the strict requirements of the automobile manufacturing industry on high-standard surface treatment quality. There is an urgent need for an ion wind curtain surface cleaning device that can self-adapt to the curved surface of the workpiece and provide full-range dead-angle-free coverage. SUMMARY

[0012] As an optional scheme of the surface cleaning device for automobile bumper processing, the rotating assembly further comprises a motor arranged on the shell, a rotating disc is arranged on the output shaft of the motor, a first gear seat is rotatably arranged on the shell, the second rotating shaft is slidably connected to the first gear seat, a second gear seat is arranged on the rotating disc, and the second gear seat is engaged with the first gear seat.

[0013] As an optional scheme of the surface cleaning device for automobile bumper processing, the first lifting seat is elastically connected to the fixed seat through a first spring, and the spherical member is elastically connected to the first lifting seat through a second spring.

[0015] As an optional scheme of the surface cleaning device for automobile bumper processing, the electrostatic dust removal device further comprises a reciprocating lifting assembly, and the reciprocating lifting assembly is used for controlling the first rotating shaft to perform reciprocating lifting movement.

[0016] The reciprocating lifting assembly comprises a second lifting seat slidably arranged on the shell, the second rotating shaft is arranged on the second lifting seat, a guide block is arranged on the second lifting seat, and a guide groove is formed in the rotating disc, and the guide block is slidably connected in the guide groove.

[0017] As an optional scheme of the surface cleaning device for automobile bumper processing, the guide groove comprises a first arc segment and a second arc segment, the height of the first arc segment is lower than that of the second arc segment, and the first arc segment and the second arc segment are connected in a head-to-tail mode.

[0020] The present application has the following advantages:

[0021] 1. This surface cleaning device for automotive bumper processing achieves adaptive and all-around coverage of the bumper's curved surface. The core of this device lies in the ion air curtain assembly, which consists of multiple arc-shaped plates elastically connected to a cylinder via a third spring. When this assembly approaches the surface of the automotive bumper, each arc-shaped plate can independently extend and retract according to the specific curved contour of the bumper, thus forming a "negative shape" structure that dynamically matches the shape of the bumper's curved surface. This design ensures that the ion air curtain ejected from all air outlets can uniformly cover the entire surface to be cleaned at the optimal distance and angle, completely eliminating cleaning dead zones caused by the fixed air duct structure, and significantly improving the uniformity and thoroughness of the cleaning.

[0022] 2. This surface cleaning device for automotive bumper processing improves the overall efficiency of electrostatic neutralization and dust removal. A conical ion curtain, combined with a high-speed airflow provided by an air pump, forms two continuous cleaning barriers. First, the high concentration of positive and negative ions generated by the ion generator is carried to the bumper surface by the airflow, quickly and evenly neutralizing the static charge and fundamentally dismantling the dust's adhesion. Then, the same airflow uses its kinetic energy to instantly blow the already "suspended" dust off the surface. This synergistic "neutralization followed by blowing" mechanism represents a qualitative leap in dust removal efficiency compared to simple blowing or ion neutralization.

[0023] 3. This surface cleaning device for automotive bumper processing intelligently links mechanical sensing and airflow control through a flow regulation component. When the cleaning brush encounters protruding or stubborn stains, its lifting motion is transmitted to the flow regulation component via the connecting ring and lifting ring, automatically increasing the airflow channel area of ​​the corresponding area's air outlet, thereby locally enhancing the wind force and flow rate of the ion wind for targeted cleaning.

[0048] In the embodiment, in order to improve the cleaning effect and facilitate the falling of dust, a cleaning brush 230 is further arranged in the middle part of the conical ion wind curtain. The installation angle of the cleaning brush 230 is not fixed, when the bottom surface of the cleaning brush 230 contacts the surface of the automobile bumper and exerts a certain force on the cleaning brush 230, according to the different radii of the region contacting the surface of the automobile bumper, the cleaning brush 230 can be attached to the curved surface of the automobile bumper.

[0049] During the process, the spherical part 253 swings relative to the axis in the first lifting seat 252 based on the vertical direction, and the first lifting seat 252 lifts relative to the fixed seat 251.

[0050] Then the rotating disc 243 and the second gear seat 245 are driven to rotate by the second motor 242, the first gear seat 244 and the second rotating shaft 241 are driven to rotate by the second gear seat 245, the first lifting seat 252 is driven to rotate by the second rotating shaft 241, the spherical part 253 is driven to rotate by the extension rod 258 between the first lifting seat 252 and the spherical part 253, and the first rotating shaft 220 and the cleaning brush 230 are driven to rotate by the spherical part 253.
