Description

Technical Field

[0001] This invention relates to the field of industrial cleaning equipment technology, specifically a cleaning device. Background Technology

[0002] Currently, the cleaning process for industrial products such as metal components, precision parts, and structural parts before processing or assembly typically employs traditional cleaning equipment that relies heavily on manual loading and unloading, using single or multiple tanks connected in series. This equipment primarily removes surface oil and impurities and performs surface treatment through steps such as degreasing, washing, passivation, and drying. However, existing cleaning equipment suffers from the following technical problems: On the one hand, traditional cleaning equipment mostly adopts a fixed tank layout, relies primarily on manual loading and unloading, has a low degree of automation, and lags behind in multi-process linkage and cycle control, failing to meet the current flexible manufacturing needs of multi-variety, small-batch production. When product models change, the equipment changeover cycle is long, and the cleaning rhythm is difficult to adjust, seriously affecting production efficiency.

[0003] On the other hand, most existing cleaning systems lack intelligent detection and data feedback functions, making it impossible to monitor and control key parameters such as cleaning fluid concentration, temperature, and workpiece condition in real time, resulting in poor cleaning quality stability. Especially in continuous production scenarios, it is impossible to judge the cleaning effect online and screen out defective products early, leading to high rework rates and high labor costs.

[0004] Furthermore, with the improvement of industrial intelligence, enterprises have put forward higher requirements for the automation, digitalization and information management of the cleaning process. However, traditional cleaning equipment has not yet realized equipment status perception, intelligent analysis and data closed-loop control based on the Industrial Internet of Things, which makes it difficult to support the needs of modern industrial systems for intelligent manufacturing.

[0005] In summary, there is an urgent need for an automated cleaning device with modular structure, intelligent operation, and online detection and rapid changeover capabilities to address the shortcomings of traditional cleaning systems in terms of automation, quality stability, and flexibility.

[0013] According to the above technical solution, the human-computer interaction terminal is equipped with a 7-inch or larger touch screen and has functions such as hierarchical permission management, alarm recording, parameter curve backtracking, and template import and export.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: This embodiment provides a cleaning device suitable for degreasing, washing, passivating and drying metal components or industrial parts. It features a modular and flexible production line layout, which can adapt to the processing needs of multiple varieties and small batches, and improve the continuity of the process and the degree of automation.

[0020] Reference Figure 1 and Figure 2 A cleaning device includes: an AGV feeding end 1, a manual feeding end 2, a tilting feeder 12, a feeding vibrating screen 14, a degreasing tank 3, a washing tank 4, a passivation tank 6, a drying tank 7, a handling robot 5, an AGV unloading end 8, a manual unloading end 9, a safety door 13, a maintenance passage 10, and a tank frame base 11.

[0021] Specifically, the AGV loading end 1 is located on one side of the device and interfaces with the automated guided vehicle. Pallet positioning is achieved through QR code recognition or RFID systems to ensure accurate material delivery. The manual loading end 2 is located on the side platform, equipped with a liftable worktable and roller conveyor belt, facilitating manual feeding by operators or temporary loading during maintenance and debugging. The tilting loading machine 12 is fixed behind the loading module and has an internal hydraulically driven tilting mechanism that can tilt the original workpieces loaded in frames or baskets 180° and use gravity for initial dispersion to prevent workpiece jamming. The loading vibrating screen 14 has a multi-stage stepped structure. A vibrating motor drives the screen to shake, achieving workpiece orientation correction and uniform distribution. The end guide groove connects to the inlet of the degreasing tank 3, ensuring accurate guidance of individual pieces to the first processing station. The degreasing tank 3 is a closed, insulated structure, with the tank body welded from stainless steel. It has an internal multi-layer spray pipeline system with fan-shaped nozzles, enabling high-temperature alkaline spray degreasing of the entire workpiece surface. After degreasing, the workpieces are gripped by the workpiece clamping device and sequentially fed into the washing tank 4, passivation tank 6, and drying tank 7. The washing tank 4 is equipped with an ultrasonic cleaning module and a circulating filter device to ensure that the degreasing residue is completely removed. The passivation tank 6 is used to chemically passivate the surface of the workpiece to improve its corrosion resistance. The drying tank 7 adopts a hot air circulation method and is equipped with multiple sets of air ducts and temperature control sensors to ensure that the workpieces are fully dried before discharge. The handling robot 5 is installed on the track guide platform and has two degrees of freedom, horizontal and vertical. The gripper end actuator can change the gripper module according to different workpiece sizes. With the help of the vision positioning system, it can achieve precise handling and greatly improve the efficiency of automated collaboration. The AGV unloading end 8 is located at the end of the cleaning line and is used to dock with the automatic guided vehicle for automatic unloading. The manual unloading end 9 is set on the side for operators to perform spot checks or small-batch manual sorting.

[0022] More specifically, safety doors 13 are installed on the outer shell of each tank and equipped with electronic interlocking devices. When an operator opens a safety door, the system immediately cuts off power and stops working to ensure maintenance safety. A maintenance passage 10 runs through the rear of the entire cleaning line, equipped with maintenance lighting and tool racks for easy periodic maintenance or equipment replacement. The entire system is mounted on the tank frame base 11, which is a welded steel structure covered with corrosion-resistant composite material plates, possessing high rigidity and chemical resistance, suitable for long-term operation under heavy loads.

[0023] Preferably, the cleaning device includes two degreasing tanks 3, two passivation tanks 6, two handling robots 5, two washing tanks 4, and three drying tanks 7.

[0024] Example 2: Based on Embodiment 1, this embodiment further provides a cleaning device control system that incorporates industrial IoT and intelligent detection technology. This system achieves comprehensive digital management and intelligent optimization control of the cleaning process through multi-dimensional sensor integration, AI visual analysis, and cloud data platform collaboration.

[0025] The control system includes: multimodal sensing nodes, edge computing processing modules, AI vision recognition units, PLC control master stations, human-machine interface (HMI) terminals, and communication interfaces between industrial gateways and cloud platforms.

[0026] Multiple sensor units are embedded in each tank (3, 4, 6, 7), including temperature sensors, liquid level sensors, pH concentration detection modules, conductivity sensors, and humidity sensors. These sensors are connected to the edge processing module via an I / O bus to collect real-time data on the cleaning fluid status and tank environmental parameters. The edge module performs preliminary filtering and fault analysis on the collected data and sends commands or alarms to the main control system.

[0027] Specifically, each cleaning station is equipped with an industrial vision inspection module, which uses a linear CCD camera with a high-brightness LED light source to acquire real-time images of the workpiece surface and identify surface deposits, scratches, or uncleaned areas. The image recognition results are input into the AI ​​analysis module. If the cleaning quality does not meet the standards, the control logic will be automatically fed back to trigger a workpiece rewash command or adaptive parameter correction (such as increasing the spray time or temperature).

[0028] More specifically, the control system of the handling robot incorporates torque feedback and displacement compensation modules, enabling real-time identification of deviations and jamming during handling, thus improving equipment operational stability. Vibration sensors and temperature rise monitoring probes are installed in key components to perform periodic operational status assessments and determine potential failure risks based on historical trends, thereby triggering maintenance recommendations or spare parts reminders in advance.

[0029] The cleaning device connects to the enterprise's MES system via an industrial gateway, establishing a data channel with the cloud data platform. It assigns a unique ID tag to the processing information of each process and each workpiece, forming an end-to-end production data loop. The system supports switching between multiple process formulas. Users can select a process template with a single click on the HMI terminal or the back-end system, automatically completing parameter calls, path scheduling, and equipment switching for each module. This enables rapid changeover for the entire production line within one hour, significantly outperforming traditional manual adjustment methods.

[0030] Furthermore, all data can be monitored graphically, allowing users to view real-time trend curves of parameters for each process segment, cleaning quality analysis results, and fault log records. Equipment health management and energy analysis are conducted through a cloud platform, improving the reliability and energy efficiency of the entire production line.
