Description

Technical Field

[0001] The present invention relates to the technical field of vehicle body treatment, in particular to an air shower room for dust removal treatment of a vehicle body. Background Art

[0002] With the development of industries such as automobile manufacturing, repair, and body painting, body surface cleaning has become a crucial step in ensuring process quality and a safe working environment. Air showers, as essential equipment for body dust removal, typically remove dust from the body surface by spraying high-speed airflow, thereby improving the cleanliness of subsequent processing steps. However, existing body dust removal systems still have the following significant shortcomings:

[0003] 1. The dust removal structure is simple and the cleaning coverage is limited: Traditional air shower rooms mostly use fixed or simple linear motion structure blowing devices, which cannot adapt to the differences in height and structural curves of different car models. Blind spots are prone to cleaning, especially in places such as car body depressions and top corners. Incomplete cleaning seriously affects the overall dust removal effect.

[0004] 2. Unadjustable wind speed, high energy consumption, and lack of fine control over the dust removal process: Existing air curtain systems mostly have constant wind speed or manually adjustable air outlets, and are unable to automatically switch wind speed modes according to vehicle type, dust level, or processing stage. There are problems such as insufficient wind speed leading to incomplete dust removal, and excessive airflow easily causing energy waste or impact on the vehicle body. The system's adaptability and intelligence are generally low.

[0005] 3. Lack of efficient dust collection methods leads to serious secondary air pollution: Dust swept away during the air shower process is often suspended in the air by the airflow. Without an efficient filtration mechanism, dust concentration in the workshop environment increases, affecting the cleanliness of subsequent spraying or testing processes and posing potential occupational health risks. Most current systems lack effective air purification and dust collection devices, making air pollution difficult to address.

[0006] In summary, existing body dust removal equipment still needs to be optimized in terms of structural flexibility, wind speed adjustment capability, and dust control methods. There is an urgent need for an integrated air shower system that can achieve multi-angle dynamic cleaning, intelligent wind speed adjustment, and air purification capabilities to meet the actual needs of modern workshops for efficient, intelligent, and environmentally friendly dust removal operations. Summary of the Invention

[0007] The present invention aims to solve the problems existing in existing vehicle body dust removal technologies, such as incomplete cleaning, unadjustable wind force, low degree of automation and inaccurate dust control, and to provide an air shower room for vehicle body dust removal with a reasonable structure, high dust removal efficiency and strong intelligent control capability.

[0008] To address the problems of existing vehicle body dust removal methods, such as inaccurate wind control, limited cleaning range, and inability to adjust the spray path according to the dynamics of the vehicle body, the present invention proposes an air shower for vehicle body dust removal that is intelligently dynamically adjustable, capable of spraying at multiple angles, and equipped with an electrostatic adsorption function.

An air outlet is opened on the surface of the shaft cylinder, and an adjusting gate is slidably mounted on the surface of the shaft cylinder. A driving rod for driving the adjusting gate to move is provided on the surface of the shaft cylinder. The opening degree of the air outlet is adjusted by driving the adjusting gate to move by the driving rod.

[0011] The air shower room is an operating space for dust removal on the vehicle body. It has a guide rail inside and multiple dust collection grids installed on one or more sides for air purification.

[0012] The trolley is equipped with a bottom sliding foot seat for longitudinal movement on the slide rail to achieve parallel movement with the vehicle body. A guide bar is fixed on one side of the trolley, and a servo mechanical arm is installed on the surface of the guide bar;

[0013] On the other side of the vehicle, multiple air curtains are mounted in a straight line along its length. Each air curtain consists of a shaft, motor, shaft, and axial flow vanes. The motor drives the shaft, which in turn rotates the axial flow vanes, ejecting a curtain of air. The shaft is equipped with air vents, whose opening is controlled by a sliding damper, which is actuated by a drive rod, enabling dynamic control of the vent opening and closing range. Air guides are located outside the multiple shaft vents. These vents are connected to form a continuous "straight-line" structure, providing a uniform, planar air curtain for simultaneous sweeping of a large area of ​​the vehicle body.

[0015] The servo robotic arm includes a pulley seat, a first axis foot, a connecting arm and a second axis foot. The pulley seat, the first axis foot and the connecting arm are all equipped with a servo drive, which can make the robotic arm swing at multiple angles. A drum fan is installed at the end for high-pressure dust removal in fine areas.

[0016] Preferably, the drum fan includes a fan volute and a wind wheel structure rotatably installed inside the fan volute, and the wind wheel rotates at high speed inside the fan volute to form a high-speed wind curtain.

[0017] Preferably, a plurality of air curtain machines are installed on the surface of the vehicle, and the plurality of air curtain machines are arranged in a straight line, each shaft cylinder surface is provided with an air guide port located at the periphery of the air outlet, and the air guide ports on each shaft cylinder surface are connected to form a continuous straight air outlet structure.

[0018] Preferably, a dust collecting grid group is provided on the side wall surface of the air shower room for communicating with the external ambient air flow. The dust collecting grid group is used to collect dust particles carried in the air flow driven by the wind curtain to keep the interior of the air shower room clean.

[0019] Preferably, the dust collecting grid group includes: a metal collecting grid, an electrode plate, a high-voltage electrostatic module and an insulating shell. The metal collecting grid is arranged in the middle of the air flow channel, and the electrode plate is arranged at the front end of the metal grid. The high-voltage electrostatic module is electrically connected to the electrode plate and the metal grid to generate an electrostatic field therebetween to adsorb particulate matter suspended in the air. The insulating shell covers the periphery of the dust collecting grid group to prevent leakage and ensure safe operation of the system.

[0020] The dust collection grid assembly operates on the principle of electrostatic adsorption. Its structure consists of a metal collection grid, an electrode plate, a high-voltage electrostatic module, and an insulating housing. The metal grid is located in the center of the main airflow channel, while the electrode plate is located at the front. The high-voltage electrostatic module provides an electrostatic field between the two, attracting particles from the airflow and purifying the air.

[0026] The beneficial effects achieved by the present invention are:

[0027] 1. In this invention, the coordinated structure of the servo robot arm and the drum fan enables multi-angle fixed-point cleaning of parts of the vehicle body at different heights and curved surfaces.

[0042] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0043] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0044] An air shower for dust removal of a vehicle body provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0045] Combine Figures 1 to 7 As shown, the present invention provides an air shower room for dust removal of a vehicle body, comprising an air shower room 100 , a trolley 200 , an air curtain machine 300 and a plurality of dust collecting grid groups 400 arranged on the surface of the air shower room 100 .

[0046] A slide rail 110 is provided on the inner side of the air shower room 100 to provide a trajectory guide for the movement of the trolley 200; a sliding foot seat 210 is provided at the bottom of the trolley 200, which can slide along the slide rail 110, thereby achieving smooth operation of the trolley 200.

[0047] A guide bar 220 is fixedly mounted on one side of the vehicle 200, on which a servo arm 230 is slidably mounted. The servo arm 230 comprises a pulley seat 231, a first pivot leg 232, a connecting arm 233, and a second pivot leg 234. The end of the second pivot leg 234 is connected to a drum fan 240. Multiple servos are located within the pulley seat 231, the first pivot leg 232, and the connecting arm 233, enabling multi-dimensional swinging motion, thereby flexibly adjusting the blowing direction of the drum fan 240. This allows the drum fan 240 to perform localized treatment on the vehicle body surface under automatic control instructions.

[0048] The drum fan 240 adopts a volute structure, and a high-speed rotating wind wheel is provided inside the volute. The wind wheel rotates in the volute to generate a directional high-speed wind curtain for fine blowing and dust removal on the surface of the vehicle body.

[0049] On the other side of the carriage 200, several air curtains 300 are installed, arranged linearly along the longitudinal direction of the carriage 200. Each air curtain 300 comprises a shaft 310, a motor 320, a shaft 321, and axial-flow rotors 330. The motor 320 drives the shaft 321, thereby driving the axial-flow rotors 330 to rotate at high speed. The shaft 310 is provided with an air vent 311 and a regulating gate 312, which is controlled by a drive rod 313. This gate automatically adjusts the air vent opening to meet the wind control requirements during different dust removal stages.

[0050] The surface of each shaft tube 310 is also provided with air guide ports, which are connected to each other in sequence to form a continuous "straight-line air outlet", so as to form a stable and uniform air flow belt and improve the coverage efficiency of different positions of the vehicle body.

[0051] The dust collection grid assembly 400 is installed on the inner wall of the air shower room 100 and communicates with the airflow channel formed by the air curtain. The dust collection grid assembly 400 utilizes the principle of electrostatic adsorption. Its structure includes a metal collection grid, an electrode plate, a high-voltage electrostatic module, and an insulating shell. The electrode plate is located at the front end. The high-voltage module is electrically connected to the electrode plate and grid, forming a high-intensity electrostatic field between the electrodes, thereby attracting dust particles suspended in the air and moving with the airflow. The insulating shell encloses the entire dust collection grid structure to ensure safe operation.

[0052] To further enhance the system's automation and intelligence, the entire system is equipped with an intelligent control module. This module receives external input commands and controls the operating status of various components, such as the motor 320, servo arm 230, drum fan 240, and regulating gate 312. Furthermore, multiple sensors, such as position detection, wind speed, and air particle concentration sensors, are located at the bottom of the vehicle 200. These sensors monitor the vehicle's position within the air shower 100, air flow conditions, and the amount of residual particles on the vehicle's surface in real time. The system dynamically adjusts the purge mode and wind speed based on this sensor data, achieving precise dust removal with high efficiency and low energy consumption.

[0053] In addition, the motor 320 of the present invention uses a variable frequency motor, which is convenient for adjusting the wind curtain intensity according to different stages, avoiding interference with the vehicle body caused by excessive wind or waste of wind energy.

[0054] The present invention realizes all-round and programmable wind cleaning of the vehicle body surface by providing a multi-directional rotating drum fan 240 and an angle-adjustable wind curtain system; combined with electrostatic dust collection, intelligent control and other functions, the dust removal efficiency and system adaptability are greatly improved.

[0055] The working principle and use process of the present invention:

[0056] The present invention provides an air shower room for dust removal of vehicle bodies. Its core working principle is: by constructing a collaborative linkage mechanism including a multi-degree-of-freedom mobile structure, a controllable air curtain blowing device and an electrostatic dust collection system, dust particles attached to the surface of the vehicle body can be removed accurately and efficiently.

[0057] The specific principles are as follows:

[0058] 1. Vehicle enters the air shower room: When the vehicle enters the preset treatment area of ​​the air shower room 100, the system detects the real-time position of the vehicle body through the sensor arranged at the bottom of the trolley 200 and uploads the data to the intelligent control module.

[0059] 2. The trolley drive system is activated: under the command of the control system, the trolley 200 moves forward and backward along the slide rail 110 provided inside the air shower room 100 through the sliding foot seat 210, so that the entire air curtain system can reciprocate along the length direction of the vehicle body.

[0060] 3. Dynamic Swinging and Blowing of Servo Arm 230: During synchronization, guide bars 220 fixed to one side of vehicle 200 drive the servo arm 230 to slide and adjust its spatial posture. Controlled by multiple servos, the servo arm 230's end is connected to a drum blower 240, which can adjust its angle in multiple directions to perform localized treatments on the vehicle's surface under automatic control.

[0061] 4. Air curtains 300 for directional dust removal: Multiple air curtains 300 are installed on the other side of the vehicle 200. Each air curtain 300 uses a motor 320 to drive axial flow vanes 330 to rotate at high speed, generating a high-speed airflow. Air outlets 311 on the shaft cylinder 310 eject the airflow. The opening of the air outlets 311 is adjusted by adjusting the gate 312 and the drive rod 313, achieving dynamic control of the wind force range and intensity. Multiple air curtains 300 are arranged in a continuous "straight line" array, simultaneously sweeping a large area of ​​the vehicle body side.

[0062] 5. Electrostatic dust collection and air purification: During the purge process, air curtains remove dust particles adhering to the vehicle body surface and carry them into the airflow within the air shower 100. This airflow is ultimately directed to the dust collection grid assembly 400 located on the inner wall of the air shower 100. A high-voltage electrostatic module within the dust collection grid assembly 400 generates a strong electrostatic field between the electrode plates and the metal collection grid, charging airborne particles and attracting them to the grid surface, achieving air purification. Furthermore, the insulated housing ensures structural electrical safety.

[0063] 6. Intelligent control system closed-loop adjustment: The entire dust removal process is scheduled by the intelligent control module: the system reads data such as vehicle body position, wind speed, particle concentration in real time, and adjusts the motor 320 speed, air outlet opening, and robotic arm posture accordingly to achieve closed-loop control and optimize dust removal efficiency and energy consumption distribution.
