Description

Technical Field

[0001] This utility model belongs to the field of automated processing equipment technology, specifically a high-voltage DC contactor electrode processing device. Background Technology

[0002] High-voltage DC contactors are crucial switching components in electric vehicles, high-voltage DC power transmission and distribution equipment, and energy storage systems. Their contact electrodes are the core components for enabling conduction and disconnection, requiring extremely stringent standards for dimensional accuracy, surface cleanliness, and assembly consistency. Contact electrodes are typically made of copper alloys or highly conductive materials, and their required structure and dimensions are achieved through high-precision machining before assembly. However, the manufacturing process of contact electrodes in existing production lines still faces several technical bottlenecks.

[0003] Firstly, in the material handling stage, most production lines still rely on manual loading and unloading operations. Operators need to move the blanks to the machine tool processing station, process them, and then remove the parts for manual or semi-automatic cleaning and sorting. This is not only labor-intensive, but the production cycle is also affected by the speed and stability of manual operation, making it difficult to achieve a continuous and balanced production rhythm. When the production workload is large or product batch changes frequently, it is more likely to cause waiting at workstations, production bottlenecks, or idle processing equipment.

[0004] Secondly, in the quality inspection stage, traditional production methods typically place tasks such as appearance inspection and posture confirmation at separate workstations before and after processing, performed manually using inspection fixtures or optical inspection equipment. This method results in long inspection cycles, difficulty in synchronizing with the production line, and the susceptibility of manual judgment to subjective factors, leading to insufficient inspection accuracy and consistency. Furthermore, the disconnect between inspection and processing / handling processes makes it difficult to promptly relay inspection results to upstream processes for adjustments, thus increasing the risk of defective products entering the processing stage.

[0005] Secondly, in the post-processing cleaning stage, commonly used handheld air guns or simple chip blowing devices have significant shortcomings. On the one hand, compressed air chip blowing has limited effectiveness in cleaning metal powder and micro-chips, especially leaving residues in holes or small gaps, affecting part performance and assembly quality. On the other hand, chip blowing disperses dust into the air, causing secondary pollution and increasing the health threat to the operator's respiratory system. Furthermore, dust accumulation inside the machine tool and on moving parts accelerates equipment wear and shortens maintenance cycles.

[0006] In terms of fixture replacement and tooling management, existing technologies mostly rely on manual disassembly or semi-automatic replacement. Switching between fixtures of different part types requires a long downtime, resulting in poor production line flexibility and making it unsuitable for multi-variety, small-batch order models. Due to the lack of automation and information support in the fixture replacement and tooling management process, replacement efficiency is low and problems such as incorrect or missing parts are prone to occur, affecting production stability.

[0007] Furthermore, the material handling methods still have significant limitations. Currently, some automated production lines use fixed conveyor belts or tracks to connect each workstation. This layout is fixed, has poor scalability, and cannot dynamically adjust the material flow direction according to the production cycle and process status. When an abnormal stop or cycle fluctuation occurs at a workstation, it can easily cause material accumulation or material shortage at the workstations before and after, reducing the overall line efficiency. When multi-path handling or cross-regional distribution is required, existing solutions also lack flexibility and intelligent scheduling capabilities.

[0008] Therefore, there is an urgent need to provide a high-voltage DC contactor electrode processing device with high structural integration, strong automation and intelligence, flexible and scalable layout, which can organically combine warehousing, handling, testing, processing, cleaning and fixture management, so as to improve production efficiency, improve finished product consistency, reduce labor costs, reduce dust pollution and adapt to the production needs of multiple varieties and small batches. Utility Model Content

[0009] The purpose of this utility model is to provide a high-voltage DC contactor electrode processing device. This device has significant advantages in terms of production capacity, quality, cost, safety and environmental performance, and is suitable for the efficient mass production of high-voltage DC contactor electrodes.

[0010] The technical solution adopted in this utility model is as follows:

[0011] A high-voltage DC contactor electrode processing device, comprising:

[0012] Machine tool;

[0013] Six-axis robots and collaborative robots mounted on the machine platform;

[0014] The first vision detection unit, which works in conjunction with the collaborative robot, is used to perform positioning identification and appearance inspection of the parts.

[0015] A first intelligent warehousing mechanism, in conjunction with the first visual detection unit, is used to store parts to be processed and parts that have already been processed;

[0016] An AGV handling robot, which works in conjunction with the first intelligent warehousing mechanism and the first vision detection unit, is used to transport materials between the two.

[0017] The machining mechanism that works in conjunction with the six-axis robot is used to process the contact electrodes on the parts;

[0018] A transfer workbench mechanism that can dock with both the six-axis robot and the collaborative robot is used to achieve posture adjustment and stable positioning during parts handover.

[0019] The negative pressure cleaning component, which works in conjunction with the collaborative robot, is used to clean the processed parts.

[0020] The first intelligent warehousing mechanism automatically docks with the AGV handling robot. The AGV handling robot can send out-of-warehouse parts to the first vision inspection unit according to the instructions of the central control system, and send the processed parts back to the first intelligent warehousing mechanism.

[0021] The six-axis robot, triggered by a qualified signal detected by the first vision detection unit, picks up the part and sends it to the processing mechanism for processing. After processing, the part is sent to the transfer workbench mechanism to dock with the collaborative robot.

[0022] The collaborative robot, after receiving the parts from the transfer workbench mechanism, drives the negative pressure cleaning component to remove metal shavings from the surface and inner holes of the parts, and after cleaning, sends the parts to the return warehouse station or assembly station.

[0023] The transfer worktable mechanism includes a rotary drive unit, a positioning element, and a clamping structure. The rotary drive unit is used to adjust the posture of the parts, the positioning element is used to prevent the parts from shifting during the transfer process, and the clamping structure is used to fix the parts during the transfer.

[0024] It also includes a second storage unit and a quick-change fixture unit, which is used to automatically change fixtures under the handling of a six-axis robot.

[0025] It also includes a second transport mechanism that works in conjunction with the second storage unit to transport the fixture or semi-finished product to the pick-and-place position of the six-axis robot.

[0026] The central control system is communicatively connected to the six-axis robot, collaborative robot, first vision inspection unit, AGV handling robot, processing mechanism and negative pressure cleaning component, and is used to realize process scheduling and safety interlock control according to the operating status of each unit.

[0027] The first visual inspection unit includes an industrial camera, a light source module, and a visual processing module. The visual processing module outputs the posture data of the part and the defect judgment result based on image recognition technology.

[0028] The negative pressure cleaning component includes a suction nozzle connected to the end of the collaborative robot, a waste collection unit, and a vacuum source. The waste collection unit includes a separation component and a filter component, used to separate metal shavings from the air and discharge clean air.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0030] This high-voltage DC contactor electrode processing device organically combines modules such as machine tool, six-axis robot, collaborative robot, intelligent warehousing, vision inspection, AGV handling, transfer workbench, processing mechanism, quick-change fixture, and transportation mechanism to form a fully automated system from raw material warehousing to finished product recycling. Each functional unit is coordinated through a central control system, sequentially connecting in the order of detection, handling, processing, cleaning, and recycling, achieving continuous material flow and seamless process integration.

[0031] A six-axis robot and a collaborative robot work together. The six-axis robot picks up a part and feeds it into the machining mechanism after a visual inspection signal is triggered. Once machining is complete, the part is transferred to the collaborative robot via a transfer table after its posture has been adjusted. The collaborative robot uses a negative pressure cleaning assembly to efficiently remove metal shavings from the surface and holes of the part, preventing secondary contamination. The cleaned part can then be directly returned to storage or proceed to subsequent processes. The transfer table provides positioning and buffering during the handover process, improving docking stability.

[0032] The first intelligent warehousing unit works in conjunction with AGV handling robots to automatically complete the inbound, outbound, and transport of materials. The second warehousing unit, combined with the quick-change fixture unit and the second transport mechanism, enables automatic fixture replacement and adjustment, shortening changeover time and enhancing the flexible production capacity of the equipment. The vision inspection unit, composed of an industrial camera, light source, and image processing module, can identify the posture of parts and determine appearance defects, ensuring processing quality from the source.

[0033] The negative pressure cleaning unit is equipped with a separation and filtration unit that collects and discharges metal shavings into clean air, reducing dust and noise and improving the working environment. The entire system's control logic has an interlock mechanism to ensure that each component operates in an orderly manner according to status signals, avoiding conflicts and malfunctions.

[0034] This device features a modular design, allowing for flexible layout and easy expansion. It can adapt to different factory buildings and process requirements without being limited to a fixed location. Automated and intelligent material handling and fixture management reduce reliance on manual labor, improving production efficiency and consistency. Integrated processing and cleaning reduce waiting and handling time, enhancing the cleanliness and reliability of finished products. The overall solution offers significant advantages in terms of capacity, quality, cost, safety, and environmental performance, making it suitable for the efficient mass production of high-voltage DC contactor electrodes.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0040] See Figures 1 to 3 This utility model relates to a high-voltage DC contactor electrode processing device, which is installed on a machine base 1. Through the coordinated operation of various automated units, the entire process of electrode processing, from warehousing and outbound, visual inspection, processing, cleaning, secondary inspection, assembly to return to the warehouse, is fully automated. This invention aims to reduce manual intervention, improve processing accuracy and production efficiency, and achieve cleanliness control of the part surface throughout the processing.

[0041] The processing device is based on machine base 1, which adopts a high-rigidity structural design to stably support multiple modules, including a six-axis robot 2, a collaborative robot 3, a first intelligent storage mechanism 4, a first vision inspection unit 5, an AGV handling robot 7, a transfer workbench mechanism 8, a processing mechanism 9, a second storage unit 10, a fixture quick-change unit 11, and a second transportation mechanism 12. The modules on machine base 1 are arranged according to the process sequence, forming a processing route from the right rear storage area to the right front inspection area, and then to the left rear processing area. Machine base 1 not only serves as a support platform but also provides the positioning reference between the modules, ensuring a stable and controllable spatial relationship between different units.

[0042] A six-axis robot 2 is positioned on the front left side of machine 1. This robot serves as the main high-speed material handling and loading / unloading unit. Its end effector is a gripper mechanism, capable of reliably grasping contact electrodes and fixtures of different shapes and sizes. Under the control system's scheduling, the six-axis robot 2 can work across multiple workstations on machine 1. It can directly pick up workpieces from the first vision inspection unit 5 and send them to the processing mechanism 9, or it can transfer processed workpieces to the collaborative robot 3 for cleaning. The six-axis robot 2's range of motion covers the processing mechanism 9, the second storage unit 10, the transfer workbench mechanism 8, and other locations, playing a pivotal role in the entire system.

[0043] A collaborative robot 3 is installed on the front right side of machine 1. This robot is characterized by safe human-robot collaboration, allowing it to work alongside operators in environments without safety barriers. A negative pressure suction nozzle is installed at the end of the collaborative robot 3, connected to a waste collection system via flexible tubing. The collaborative robot 3 is primarily responsible for post-processing cleaning. After receiving parts from the six-axis robot 2, it moves the parts to the cleaning station and uses negative pressure suction to draw metal shavings and dust from the surface of the parts and within the machined holes into the waste collection system. After cleaning, the collaborative robot 3 can return the parts to the transfer workbench mechanism 8, the assembly station, or directly hand them over to the AGV handling robot 7 for return to storage.

[0044] To the right rear of machine 1 is the first intelligent storage mechanism 4, a three-dimensional rack structure that enables multi-level material storage within a limited floor space. Each rack within storage mechanism 4 can hold a material box for storing electrodes awaiting processing or finished products. Storage mechanism 4 is equipped with lifting and transfer devices, capable of delivering material boxes to designated locations to the discharge port for docking with the AGV handling robot 7. Storage mechanism 4 is not only a material storage unit but also the starting and ending point of the entire processing system; all workpieces are dispatched from here at the beginning of the processing flow and returned here at the end.

[0045] The first vision inspection unit 5 is located between the six-axis robot 2 and the first intelligent storage mechanism 4. Its base is fixed on the machine base 1 and it is equipped with an industrial camera, a ring light source, and a vision processing system. When the AGV handling robot 7 removes the toy box from the storage mechanism 4 and places it in the inspection unit 5, the vision inspection unit 5 starts the shooting program, using the light source to provide uniform illumination and eliminate ambient light interference. The vision system identifies the posture and position of the parts through algorithms, while detecting defects, burrs, or dimensional deviations on the surface of the parts, and transmits the detection results to the central control system in real time. If the detection result is qualified, the control system will dispatch the six-axis robot 2 to send the parts to the processing mechanism 9; if the detection is unqualified, it will notify the AGV handling robot 7 to send the batch of parts back to the storage mechanism 4 to prevent defective products from entering the subsequent processing stage.

[0046] The AGV handling robot 7 operates in the aisle to the right of machine 1, traveling back and forth between the storage unit 4 and machine 1 along a preset navigation path. Equipped with a forklift platform, the AGV handling robot 7 can perform docking and loading operations according to the different heights of the storage unit 4. Its main function is to undertake long-distance material handling tasks, delivering outgoing material boxes to the first vision inspection unit 5, or returning processed parts to the storage unit 4 for storage. The operation of the AGV handling robot 7 does not interfere with the six-axis robot 2 and the collaborative robot 3, achieving seamless coordination through scheduling by the central control system.

[0047] A transfer table mechanism 8 is arranged between the six-axis robot 2 and the collaborative robot 3. This table is rotatable and equipped with positioning pins and clamping structures to ensure that the workpiece does not shift during the robot handover process. After the six-axis robot 2 places the processed part on the transfer table mechanism 8, the table can rotate to an angle that is easy for the collaborative robot 3 to grasp, achieving a smooth workpiece handover. Similarly, after the collaborative robot 3 completes cleaning or assembly operations, the workpiece can also be returned to the six-axis robot 2 or the AGV handling robot 7 through the transfer table mechanism 8.

[0048] The machining mechanism 9, located directly behind the six-axis robot 2, is the core of the entire system's machining process. In this embodiment, the machining mechanism 9 employs CNC machining equipment, capable of performing various machining operations such as drilling, milling, and chamfering. The machining mechanism 9 and the six-axis robot 2 are interlocked via a control system. While the machine tool is running, the six-axis robot 2 cannot enter the machining area, thus ensuring the safety of personnel and equipment. During machining, the six-axis robot 2 accurately places the workpiece into the fixture of the machining mechanism 9. The machining mechanism 9 executes a preset machining program, and upon completion, notifies the six-axis robot 2 to remove the workpiece and send it to the next workstation.

[0049] A second storage unit 10 is located at the front left of the machine tool 1, used to store fixtures or semi-finished products of different specifications. A fixture quick-change unit 11 is installed directly behind the second storage unit 10. It adopts a quick-change base structure, allowing the six-axis robot 2 to automatically remove the current fixture and replace it with a new one according to changes in the processing task, without manual intervention, thus improving processing flexibility and efficiency. A second transport mechanism 12 is located in front of the second storage unit 10, using a conveyor structure to transport fixtures or workpieces to a position where the six-axis robot 2 can grasp them, forming a material circulation with the second storage unit 10.

[0050] The cleaning system plays a crucial role throughout the entire processing flow. The negative pressure suction nozzle at the end of the collaborative robot 3 is connected to a waste collection unit. This unit uses a cyclone separator and filter to separate the sucked-in metal shavings from the air, expelling the purified air and ensuring a clean working environment. The suction power of the negative pressure nozzle can be automatically adjusted according to the characteristics of the parts to prevent damage to the part surfaces during cleaning.

[0051] The processing flow of this invention is as follows: First, the AGV handling robot 7 takes out the material box containing the parts to be processed from the first intelligent storage mechanism 4 and transports it to the first vision inspection unit 5; the vision inspection unit 5 identifies the position and posture of the parts and detects appearance defects, and transmits the information of qualified parts to the control system; after receiving the instruction, the six-axis robot 2 picks up the qualified parts and sends them to the processing mechanism 9 for processing; after processing, the six-axis robot 2 places the parts on the transfer workbench mechanism 8, and the collaborative robot 3 picks them up to the cleaning station for negative pressure cleaning; after cleaning, the parts can be selected to undergo secondary vision inspection to ensure that there are no residues or defects on the surface; finally, the qualified parts are handed over by the collaborative robot 3 or the six-axis robot 2 to the AGV handling robot 7 and sent back to the first intelligent storage mechanism 4 for classified storage, or directly sent to the assembly line for the next process.

[0052] In the interaction between the various modules, the central control system plays a central role. Based on the real-time status of each workstation, it coordinates the working sequence of the AGV handling robot 7, the six-axis robot 2, the collaborative robot 3, and the processing mechanism 9, ensuring that the actions of each module do not conflict at any given time. Information transmission between the first vision inspection unit 5 and the processing mechanism 9 ensures that defective products do not enter the processing stage, thereby reducing the scrap rate. The transfer workbench mechanism 8 optimizes the posture during robot handover, improving the stability and accuracy of the grasping process.

[0053] Through the coordinated operation of the aforementioned units, this invention achieves a fully automated processing flow from raw material outbound to finished product return. The AGV handling robot 7 enables long-distance transport between the warehouse and the machine station 1; the six-axis robot 2 performs rapid and precise loading and unloading operations; the collaborative robot 3 performs meticulous cleaning and possible assembly work; the first vision inspection unit 5 ensures quality control; the processing mechanism 9 completes high-precision electrode processing; and the warehousing systems 4 and 10 achieve high-density material management. Through the rational physical arrangement of the units and the coordinated scheduling of the control system, a high-efficiency, low-error-rate production mode is achieved.

[0054] Compared to traditional manual handling, inspection, and cleaning methods, this invention not only reduces labor costs but also improves processing stability and consistency. Simultaneously, the introduction of a cleaning system effectively solves the problem of incomplete removal of surface debris after processing, avoiding potential hazards during subsequent assembly and use. Through modular design, the processing device of this invention can be expanded or adjusted according to different production needs, such as adding more storage units, configuring different types of processing mechanisms, or adding assembly modules, thereby adapting to multi-variety, small-batch, or large-batch production modes.

[0055] In summary, this invention, through the synergistic action of machine tool 1, six-axis robot 2, collaborative robot 3, first intelligent warehousing mechanism 4, first vision inspection unit 5, AGV handling robot 7, transfer workbench mechanism 8, processing mechanism 9, second warehousing unit 10, fixture quick-change unit 11, second transportation mechanism 12, and cleaning system, achieves automated processing and management of high-voltage DC contactor electrodes, ensuring processing accuracy, improving production efficiency, and enhancing the cleanliness of the working environment.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
