Description

Technical Field

[0001] The utility model relates to the technical field of silos, in particular to a multi-layer material storage device. Background Art

[0002] As people's living standards improve, the shortage of human resources for front-line workers in the machining industry is becoming more and more serious, and more and more manufacturing factories have begun to transition to automation and intelligence. Six-axis robots replace manual assembly, and truss manipulators are equipped with CNC machine tools to process parts, which are already very common in the market. However, with the increasing use of manipulators, whether it is assembly or production and processing, the limitations of silo storage, the speed of material change, and the stability of silo use have always affected the degree of automation of the factory, especially in large-scale, short-cycle processing and assembly sites. During the operation, problems with the silo or restrictions on the output rhythm have a great impact on the factory's production capacity. When the product needs to feed the six-shutdown robot in a fixed posture, an immovable single-layer or double-layer silo is generally used for material storage, which has poor flexibility. A single-layer silo can only place materials in a single layer, with a small storage capacity, and manual material change is more frequent. When manual material change is performed, the six-joint robot needs to stop working for a long time, which reduces production efficiency. Double-layer silos place materials in double layers, and the storage capacity is slightly higher than that of single-layer silos, but it is still subject to greater restrictions. Manual material change is also more frequent than that of single-layer silos, affecting production efficiency. Utility Model Content

[0003] Technical problems to be solved by utility models

[0004] In view of the technical problems of small material storage capacity, frequent manual material replacement and low production efficiency in traditional silos, the utility model provides a multi-layer material storage device, which increases the material storage capacity, avoids frequent manual material replacement, can quickly switch silos, reduces robot downtime, and improves production efficiency.

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the utility model is:

[0007] A multi-layer material storage device comprises a fixed station, including a base structure and a sensor assembly; a movable material bin, including a slidably connected material bin frame and a multi-layer material tray assembly, the bottom of the movable material bin is provided with a movable structure, the movable structure cooperates with the base structure, the material tray assembly cooperates with the sensor assembly to detect the position of the material tray, and the movable material bin is provided with an opening; a robot is provided with a material picking structure, and the material picking structure is opposite to the opening.

[0008] Fixed site: It consists of a base structure and a sensor assembly. The base structure provides stable support, while the sensor assembly is used to accurately detect the position and status of the movable silo to ensure that the robot can operate accurately.

[0009] Movable silo: The sliding-connected silo frame and multi-layer tray assembly design allow the silo to move smoothly on the base. At the same time, the multi-layer tray assembly can significantly increase storage capacity, reduce the frequency of material changes, and improve overall efficiency.

[0010] Coordination between the mobile structure and the base structure: Through the well-designed docking between the mobile structure and the base structure, it is ensured that the movable silo can move smoothly on the fixed site, so as to achieve the purpose of rapid switching of silos.

[0011] Coordination between sensor assembly and tray assembly: The sensor assembly can monitor the position and status of the tray in real time, which is crucial for automated operation and ensures the accuracy and safety of the robot when picking up and placing materials.

[0012] Coordination between robot and opening: The robot is equipped with a special material-retrieving structure, which is aligned with the opening on the movable silo, allowing the robot to quickly and accurately take out or put materials from the tray, reducing the robot's waiting time and downtime, and greatly improving the efficiency of the production line.

[0013] Optionally, the sensor assembly and the tray assembly are both arranged vertically, and the sensors and the trays correspond one to one.

[0014] Precise positioning: Since each sensor directly corresponds to a tray, the system can very accurately identify the position and status of each tray. When the robot needs to operate a specific tray, the system can quickly locate and feedback information to ensure the accuracy of the operation.

[0015] Efficient communication: The vertically arranged sensor components can form a direct communication link with the tray components, reducing interference and delays in signal transmission and improving the speed and reliability of data exchange.

[0016] Simplified control system: Due to the one-to-one relationship between the sensor and the tray, the logic of the control system becomes simpler and more intuitive. For each change in the state of the tray, the system only needs to process the corresponding sensor data, without the need for complex algorithms to parse and match.

[0017] Easy maintenance and expansion: This design makes the system more convenient for maintenance and troubleshooting. If a tray or its corresponding sensor has a problem, it can be directly located at the specific location, reducing maintenance time. At the same time, when the storage capacity needs to be increased, just add more trays and sensors in the same mode, and the system has good scalability.

[0018] Optimize space utilization: The vertical arrangement design makes full use of the vertical space. Compared with the horizontal layout, it can provide more storage levels in a limited space, further improving the density and efficiency of the storage device.

[0019] Optionally, the base structure is provided with a silo locking device cooperating with the movable silo.

[0020] Ensure stability: When the movable silo is docked with the base structure, the silo locking device can firmly fix the silo to the base to prevent the silo from moving due to unexpected vibration or external impact, thereby ensuring the stability and safety of the entire system.

[0021] Improved operational accuracy: The locking device ensures that the bin remains stationary during operation, which is especially important for robots that require high-precision operations. Whether it is picking up or putting down materials, a stable bin position can help the robot perform tasks more accurately and reduce operational errors.

[0022] Enhanced safety: In an automated production environment, safety is always the primary consideration. The silo locking device can prevent the silo from accidentally moving without request, avoiding possible collision or falling accidents, protecting the safety of operators and equipment.

[0023] Optionally, the silo locking device includes a rotatable lock buckle, which is movably engaged with the bottom of the movable silo.

[0024] Easy to switch quickly: The silo locking device is designed as a rotatable quick-lock structure, which means that when replacing the silo, the operator or automated equipment can quickly unlock the old silo and lock the new silo, greatly shortening the silo switching time and improving the continuity and efficiency of the production process.

[0025] Optionally, a base positioning bracket cooperating with the movable silo is provided on the inner side of the base structure.

[0026] Precise positioning: The base positioning bracket can ensure the precise position of the movable silo when docking, which is the basis of automated operation. Through the positioning bracket, the movable silo can be accurately docked at the preset position, so that the sensor component, the tray component and the robot material picking structure can be seamlessly connected, improving the accuracy and efficiency of the operation.

[0027] Enhanced stability: The positioning bracket provides additional physical support, especially when the movable silo is fully loaded with heavy objects, it can effectively disperse the load, reduce stress concentration on the base structure and silo frame, and ensure the structural stability and safety of the entire system.

[0028] Optionally, a buffer pad is provided on the inner side of the base structure opposite to the entry direction of the movable silo.

[0029] Shock absorption and anti-collision: When the movable silo approaches the base structure to complete docking, the buffer pad can absorb the impact energy, reduce the hard contact between the silo and the base, effectively prevent vibration and noise caused by impact, and protect the equipment from damage.

[0030] Optionally, a pulley rail structure is provided between the tray assembly and the silo frame, and the rail cooperates with a plurality of evenly distributed pulleys.

[0031] Low friction: The rolling friction between the pulley and the slide rail is much smaller than the direct sliding friction, which means that the material tray requires less push or pull force when moving, thereby reducing power consumption and improving operating efficiency.

[0032] Smooth movement: The pulley and slide structure ensures that the tray assembly can move smoothly along the predetermined track, avoiding vibration and shaking caused by uneven friction or jamming, which is essential for protecting sensitive materials and maintaining operational accuracy.

[0033] Load-bearing capacity: The design of the slide rails and pulleys usually takes into account the load-bearing capacity and stability, and can maintain good mobility even under heavy load conditions, which is suitable for storing heavy materials.

[0034] Precise positioning: The slide rail provides precise guidance for the tray assembly. Combined with the detection of the sensor assembly, the tray can be accurately positioned, which is essential for automated operation.

[0035] Optionally, the tray assembly includes a tray body, a tray and a pull-out bracket, the tray body is located on the tray, and the pull-out bracket is fixed to the edge of the tray.

[0036] As the supporting platform of the tray body, the tray not only bears the weight of the material, but also cooperates with the pulley and slide rail structure to ensure the stability and safety of the tray assembly when moving. The strength and stability of the tray directly affect the reliability and service life of the entire tray assembly. The design of the pull-out bracket allows the tray to be easily pulled out from the silo frame, which is convenient for loading, unloading and inspection of materials. The pull-out bracket is usually fixed to the edge of the tray to provide additional support and guidance to ensure stability and smoothness during the pulling process. The pull-out design greatly improves operational efficiency. Operators or robots can directly access specific trays without moving the entire silo, reducing the time and labor intensity of material handling.

[0037] As an option, a drawer is also included, and the drawer is located at the bottom of the device.

[0038] The drawer is used to collect waste liquid flowing out of the tray assembly, and the drawer can be pulled out to drain the waste liquid.

[0041] The technical solution provided by the utility model sets up a multi-layer tray assembly and a fixed station with a split matching design and a movable silo, which not only increases the storage capacity and reduces manual intervention, but also greatly improves production efficiency by quickly switching silos and reducing robot downtime. At the same time, the improvement of the degree of automation also reduces the error rate and ensures the continuity and stability of the production process. And by combining precise mechanical design and advanced sensing technology, a high degree of automation of material storage and retrieval is achieved. BRIEF DESCRIPTION OF THE DRAWINGS
