Description

Technical Field

[0001] This invention relates to the field of chemical laboratory equipment technology, and more specifically, to a robotic arm trolley for handling and transporting waste liquids and materials in chemical laboratories. Background Technology

[0002] With the increasing frequency of research activities in chemical laboratories, the amount of hazardous waste generated has increased significantly. Currently, the disposal of laboratory waste mainly relies on manual handling or simple trolley transport, resulting in highly fragmented functions. Some equipment can only collect liquid waste or transport solid waste independently, failing to achieve integrated operation; liquid waste collection often uses ordinary plastic containers, which cannot meet the needs of classifying and storing different types of chemical waste such as acids and alkalis; solid waste often requires additional crushing equipment for processing before transport, making the process cumbersome. In addition, existing equipment has significant deficiencies in corrosion resistance and antistatic properties, making it difficult to adapt to the highly corrosive and static-prone environment of chemical laboratories. During transport, problems such as spillage of liquid waste and leakage of exhaust gas are prone to occur, increasing the workload of laboratory personnel and posing safety hazards.

[0003] In recent years, robotic arms have been widely used in industrial applications for material handling, but their application in chemical laboratory settings still faces many limitations. Existing laboratory robotic arms are functionally limited, only capable of basic handling actions, and are not effectively integrated with functions such as waste liquid sorting and collection, waste material crushing, and exhaust gas purification. Furthermore, industrial robotic arms are bulky and difficult to adapt to the confined spaces of laboratories, and their insufficient gripping precision can easily lead to container damage or material spillage. More importantly, existing equipment generally lacks intelligent monitoring and linkage mechanisms, making it impossible to monitor waste liquid levels and waste material loading in real time, hindering the standardized and traceable management of hazardous waste. Therefore, there is an urgent need to develop an intelligent handling device that integrates robotic arm operation, waste liquid sorting and treatment, and waste material crushing and collection.

[0025] To facilitate understanding of the above technical solutions of the present invention, the following embodiments will be used to describe the above technical solutions of the present invention in detail.

[0026] Example 1 A robotic arm trolley for handling waste liquids and materials in a chemical laboratory includes a frame assembly, a waste liquid handling assembly, a waste material handling assembly, an auxiliary protection assembly, an intelligent monitoring assembly, a movement limiting assembly, and a robotic arm assembly. All components are integrated into one unit, resulting in a compact structure suitable for use in the confined spaces of a chemical laboratory.

[0027] The chassis assembly is constructed from a steel frame encased in 8mm thick porcelain-white PP sheet, with overall dimensions of 1200mm × 800mm × 1500mm, exhibiting excellent robustness and strong corrosion resistance. The steel frame enhances the overall load-bearing capacity, accommodating the weight and operational load of the robotic arm assembly, while the PP sheet isolates corrosive chemical waste from contact with the steel, preventing equipment damage. A dust cover is installed on the top of the chassis, connected to the chassis via a spring-damped hinge with an opening angle of 0 to 90 degrees. This prevents dust and debris from clogging the waste collection port, waste material inlet, and robotic arm mounting interface, and allows the cover to be secured during use, preventing closure from interfering with operation. A push-pull handle is located on one side of the chassis, made of PP material with a non-slip textured surface, improving grip comfort and stability, facilitating equipment movement, and meeting the frequent transport needs of chemical laboratories. A reinforced mounting base is installed on the top of the frame corresponding to the installation position of the robotic arm. It is made of stainless steel with an anti-corrosion coating and is fixed to the base of the robotic arm with high-strength bolts to ensure the stability of the robotic arm during operation and prevent shaking that could lead to gripping deviation or waste liquid spillage.

[0028] The waste liquid treatment assembly includes a waste liquid collection tank, an anti-static funnel, a one-way check valve, a waste gas purification device, a spill containment tray, and a water supply pipeline. The waste liquid collection tank is made of highly corrosion-resistant HDPE material, with a capacity of 20L. It supports single or double tank designs. The double tank design can separately collect acidic and alkaline chemical waste liquids to avoid mixing reactions. The tank body and the vehicle frame assembly are detachably connected, facilitating subsequent standardized transfer of chemical waste liquids and tank cleaning, meeting hazardous waste storage requirements. The spill containment tray is entirely made of HDPE material and installed below the waste liquid collection tank. It effectively catches spilled chemical waste liquids, preventing ground corrosion, safety accidents, or secondary pollution. The anti-static funnel is made of anti-static HDPE material and installed on the top of the vehicle frame corresponding to the waste liquid collection tank. The funnel is equipped with an anti-static grounding clamp, which is connected to a grounding wire and fixed in a dedicated clamp hole in the funnel. This quickly guides static electricity generated during the pouring of chemical waste liquids to the ground, eliminating static electricity hazards.

[0029] The one-way check valve, made of PTFE, is installed at the bottom of the anti-static funnel and connected to the waste liquid collection tank. It prevents volatile chemical waste gases from flowing back into the laboratory, thus avoiding environmental pollution. The exhaust gas purification device, with an anti-static HDPE shell, is installed on the side of the vehicle frame and connected to the waste liquid collection tank via a pipe. It can specifically treat vaporized volatile organic compounds, acids, alkalis, and other chemical waste gases within the tank. Using activated carbon adsorption, the treated gas meets the requirements of the "Integrated Emission Standard for Volatile Organic Compounds from Stationary Sources" and the "Emission Limits for Air Pollutants." The device includes a time progress bar for easy and intuitive assessment of its effective period, meeting routine purification needs for 6 months. One end of the water supply pipeline connects to an external water source or an internal water tank, while the other end extends to the vicinity of the funnel. This allows for rinsing the funnel when waste liquid is poured out, preventing chemical waste residue from corroding the funnel or causing cross-contamination. It also rinses the end effector of the robotic arm to remove chemical residues.

[0030] The waste treatment assembly includes a waste inlet, a crushing mechanism, an atomizing dust suppression mechanism, and a waste collection chamber. The waste inlet is located on the top of the vehicle frame and connects to the waste collection chamber. The inlet has a flip-up cover that closes when not in use to prevent chemical dust from overflowing. The cover can be opened via a robotic arm without manual operation. The crushing mechanism is installed below the waste inlet and above the waste collection chamber. It includes two crushing gears with serrated surfaces to significantly improve cutting and crushing capabilities. The crushing gears are made of stainless steel with an anti-corrosion coating, suitable for crushing chemical solid waste. The crushing gears are driven by a motor installed in a sealed PP material housing inside the vehicle frame to prevent chemical waste liquids and dust from entering and damaging the motor. The crushing gears rotate in opposite directions, effectively crushing the input chemical solid waste (such as reagent residues, expired reagents, and contaminated fragments) to reduce its volume, facilitating collection and subsequent centralized disposal of hazardous waste.

[0031] The atomizing dust suppression mechanism includes a water supply pipe, a water pump, and atomizing nozzles. The water supply pipe is arranged circumferentially along the arc-shaped inner wall of the crushing gear. The atomizing nozzles are evenly installed on the water supply pipe. The water pump is connected to the water supply pipe and can draw water from an internal water tank or an external water source to supply the atomizing nozzles. When the crushing gear is working, the atomizing nozzles spray a uniform water mist to cool and suppress the chemical dust generated during the crushing process, preventing dust from spreading and polluting the chemical laboratory environment. It also reduces the harm of chemicals in the dust to personnel and the robotic arm, and prevents dust from entering the robotic arm joints and causing jamming. The waste collection chamber is located on the other side of the frame, separated from the waste liquid treatment component to prevent secondary pollution caused by mixing chemical waste liquid and waste. The bottom of the collection chamber has an inclined surface for easy centralized waste stacking. The side of the collection chamber has an openable unloading door, which is secured by a sealing lock. When closed, it has good sealing performance to prevent dust leakage. When opened, the waste can be cleaned with the assistance of the robotic arm, quickly discharging the crushed waste for standardized transportation and disposal.

[0032] The auxiliary protective components include a folding fence, seals, safety signs, and a protective cover for the robotic arm. The folding fence, installed on the top edge of the frame, can be folded for storage. When unfolded, it prevents spillage of chemical waste, waste material input, and splashing during robotic arm operation. When folded, it does not occupy extra space, facilitating equipment movement in confined spaces. The seals, made of corrosion-resistant rubber, are installed at connections such as the unloading door, waste collection tank interface, and dust cover, improving sealing and preventing leakage of chemical waste, dust spillage, and exhaust gas. The frame surface is affixed with prominent safety signs, including corrosion warnings, anti-static warnings, load limit warnings, and hazardous waste disposal warnings, along with instructions for waste liquid and waste material classification and storage, enhancing operational awareness, standardizing personnel operations, and complying with chemical laboratory safety management requirements. The robotic arm protective cover is made of transparent and corrosion-resistant PC material, which can fully cover the main body and joints of the robotic arm. The surface of the protective cover is treated with anti-static agents, which can prevent chemical reagents and dust from contacting and corroding the robotic arm, and avoid the hidden dangers caused by static electricity generated during the operation of the robotic arm. At the same time, it does not affect the operator's observation of the operation process. The protective cover can be disassembled and removed for easy maintenance of the robotic arm.

[0033] The intelligent monitoring component includes a wireless liquid level alarm device, a weighing sensor, a QR code scanner, a robotic arm positioning sensor, and a central controller. The central controller incorporates a waste liquid-waste material collaborative processing logic algorithm. Based on data such as the waste liquid level monitored by the wireless liquid level alarm device, the waste weight collected by the weighing sensor, and the waste type identified by the QR code scanner, combined with the real-time load status of the equipment, it intelligently plans the robotic arm's operating sequence and waste material crushing timing under the guidance of the robotic arm positioning sensor, achieving efficient collaborative processing of waste liquid and waste materials. Simultaneously, this intelligent monitoring component possesses predictive maintenance capabilities. The central controller can monitor relevant operating data such as robotic arm joint wear, changes in crushing gear torque, and decrease in exhaust gas purification efficiency in real time, providing early warnings of equipment maintenance needs, reducing equipment failure rates, and ensuring stable system operation. The wireless liquid level alarm device, with a PP material housing, is installed inside the waste liquid collection tank and includes a liquid level detection switch, a signal transmitter, and an alarm host. It can monitor the liquid level in the chemical waste liquid collection tank in real time. When the liquid level reaches a preset threshold, it sends an alarm message to the central controller via wireless signal, eliminating the need for wiring and reducing safety risks. Weighing sensors are installed at the bottom of the vehicle frame, corresponding to the positions of the waste liquid collection tank and the waste material collection chamber, respectively. They can detect the loaded weight of waste liquid and waste material in real time, preventing equipment overloading. The weighing data can be transmitted to the central controller and external terminals or display panels for easy hazardous waste weight statistics. A QR code scanner is installed near the push-pull handle, which can scan and record different types of chemical waste liquids and waste materials, labeling information such as waste category and generation time. This enables full traceability of hazardous waste transportation, solving the problems of tedious and error-prone manual recording and contributing to the standardized management of hazardous waste in laboratories.

[0034] Positioning sensors are installed on each joint and end effector of the robotic arm, enabling real-time detection of its position and posture. This allows for precise control of gripping and placement accuracy, with an error not exceeding ±2mm, preventing operational deviations that could lead to waste spillage or material scattering. The sensors also detect the distance between the robotic arm and surrounding structures to prevent collision damage. The central controller, with its corrosion-resistant and sealed structure, is installed inside the frame and is linked to the robotic arm assembly, waste liquid treatment assembly, waste material treatment assembly, intelligent monitoring assembly, and movement limit assembly. It receives data from each sensor and controls the robotic arm to perform gripping, transporting, and placement actions. When the liquid level or weight reaches a threshold, the controller stops the loading operation and issues an alarm. Simultaneously, it records the robotic arm's operational trajectory and waste liquid / material handling information.

[0035] Example 2 A robotic arm trolley for handling waste liquids and materials in a chemical laboratory includes a frame assembly, a waste liquid handling assembly, a waste material handling assembly, an auxiliary protection assembly, an intelligent monitoring assembly, a movement limiting assembly, and a robotic arm assembly. All components are integrated into one unit, resulting in a compact structure suitable for use in the confined spaces of a chemical laboratory.

[0036] The chassis assembly is constructed from a steel frame encased in 10mm thick carbon fiber reinforced polyamide (CFRP) sheet, with overall dimensions of 1200mm × 800mm × 1600mm, offering excellent lightweight design and high strength and rigidity. The steel frame enhances overall load-bearing capacity, accommodating the weight and operational load of the robotic arm assembly. The CFRP sheet provides excellent corrosion resistance, preventing contact between corrosive chemical waste and the steel, thus avoiding equipment damage. A dust cover is installed on the top of the chassis, connected to the chassis via a torsion spring damping hinge. The hinge opening angle is from 0 to 90 degrees, preventing dust and debris from clogging the waste collection port, waste material inlet, and robotic arm mounting interface. The cover can also be secured during use to prevent closure from interfering with operation. A push-pull handle is located on one side of the chassis, made of polycarbonate (PC) with a non-slip textured surface, improving grip comfort and stability, facilitating equipment movement, and meeting the frequent transport needs of chemical laboratories. A reinforced mounting base is installed on the top of the frame corresponding to the installation position of the robotic arm. It is made of titanium alloy with an anti-corrosion coating and is fixed to the base of the robotic arm with high-strength bolts to ensure the stability of the robotic arm during operation and prevent shaking that could lead to gripping deviation or waste liquid spillage.

[0037] The waste liquid treatment assembly includes a waste liquid collection tank, an anti-static funnel, a one-way check valve, a waste gas purification device, a spill containment tray, and a water supply pipeline.

The spill containment tray is made entirely of polypropylene (PP) material and is installed below the waste liquid collection tank, effectively catching spilled chemical waste liquid and preventing ground corrosion, safety accidents, or secondary pollution. The anti-static funnel is made of anti-static polyamide (PA) material and is installed on the top of the vehicle frame corresponding to the waste liquid collection tank. The funnel is equipped with an anti-static grounding clamp, which is connected to a grounding wire and fixed in a dedicated clamp hole in the funnel, quickly guiding static electricity generated during the pouring of chemical waste liquid to the ground and eliminating static electricity hazards.

[0038] The one-way check valve, made of polytetrafluoroethylene (PTFE), is installed at the bottom of the anti-static funnel and connected to the waste liquid collection tank. It prevents volatile chemical waste gases from flowing back into the laboratory, thus avoiding environmental pollution. The exhaust gas purification device, with an anti-static polycarbonate (PC) shell, is installed on the side of the vehicle frame and connected to the waste liquid collection tank via a pipe. It can specifically treat vaporized volatile organic compounds, acids, alkalis, and other chemical waste gases within the tank, employing an acid-alkali spray washing and absorption process. The treated gas meets the requirements of the "Integrated Emission Standard for Volatile Organic Compounds from Stationary Sources" and the "Emission Limits for Air Pollutants." The device includes a time progress bar for easy and intuitive assessment of its effective period, meeting routine purification needs for 6 months. One end of the water supply pipeline connects to an external water source or an internal water tank, while the other end extends to the vicinity of the funnel. This allows for flushing of the funnel during waste liquid pouring, preventing chemical waste residue from corroding the funnel or causing cross-contamination. It also flushes the end effector of the robotic arm to remove chemical residues.
