Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Example 1: See Figures 1 to 4 As shown, this utility model provides an embodiment of a material handling robot.

[0029] In this embodiment, the material is silver paste, which is stored in silver paste container 1.

[0030] Material handling robots include:

[0031] The mobile chassis 2 can be moved to a designated location;

[0032] Storage cabinet 3 is installed on the aforementioned mobile chassis 2. Storage cabinet 3 includes a first identification device 31, a second identification device 32, multiple storage compartments 33, and multiple weight sensors 34. The first identification device 31 is used to identify the identity of the staff. The second identification device 32 is used to identify the code of the silver paste tank 1. The storage compartment 33 is used to store the silver paste tank 1. The storage compartment 33 is provided with a cabinet door 35 for opening and closing its opening and a door lock 36 for locking and unlocking the cabinet door 35. The weight sensors 34 correspond one-to-one with the storage compartments 33. The weight sensors 34 are used to weigh the silver paste tank 1 in the corresponding storage compartment 33.

[0033] The control system is connected to the aforementioned mobile chassis 2, the aforementioned first identification device 31, the aforementioned second identification device 32, and the aforementioned door lock 36.

[0034] In the above description, the mobile chassis 2 is the foundation of the entire material handling robot, enabling it to move to different work positions. The mobile chassis 2 can move to a set location according to a pre-set route, or it can autonomously plan and find its own route to reach the set location. Specifically, in this embodiment, the mobile chassis 2 can move autonomously. The mobile chassis 2 can be an AGV, AMR, or other autonomously movable robot chassis to achieve autonomous movement to different locations.

[0035] The first identification device 31 is an identity recognition device that can collect, process, and compare an individual's identity information to determine whether the identity is legal or matches, and upload the result of whether the identity is legal or matches to the control system. There are many types of first identification devices 31, which will be further explained later.

[0036] The second identification device 32 is an encoding identification device capable of reading, parsing, and identifying the encoding of the silver paste container 1, and uploading the encoding of the silver paste container 1 to the control system. The second identification device 32 will be further described later.

[0037] Storage compartment 33 is a space that can accommodate the silver paste container 1. When the cabinet door 35 is closed and the door lock 36 is engaged with the latch 351 on the cabinet door 35, the silver paste container 1 cannot be removed from the storage compartment 33. Only after the door lock 36 is unlocked and the latch 351 on the cabinet door 35 is opened can the silver paste container be removed from the storage compartment 33. Specifically, the door lock has a built-in pop-out function, which allows for automatic opening upon receiving an opening command, facilitating manual operation.

[0038] Multiple storage compartments 33 are set up in zones according to the slurry to be stored. The layout of the multiple storage compartments 33 will be further explained later.

[0039] The weight sensor 34, also known as a load cell, is used to convert the weight of the silver paste tank 1 into a measurable electrical signal and upload it to the control system. The weight sensor 34 has a measurement accuracy of up to 0.01g and can provide weight assessment feedback for the discharge and return of silver paste from the tank. Therefore, through automation and digital tools, the characteristics and flow of silver paste can be controlled, improving the average silver paste consumption per unit from both human and material perspectives.

[0040] The control system controls the movement of the mobile chassis 2, enabling material turnover via a robot, which improves production efficiency and reduces costs. Both the storage bin 33 and the silver paste bucket 1 have unique corresponding codes. The control system controls the door lock 36 to open and stores the code of the opened storage bin 33 based on the identity information identified by the first identification device 31; it matches the number of the silver paste bucket 1 with the number of the storage bin 33 based on the code information identified by the second identification device 32 and stores it; and it matches the weight of the silver paste bucket 1 with its number based on the weight data measured by the weight sensor 34 and stores it. In this way, the personnel, storage bin, and weight corresponding to each silver paste bucket are monitored, improving material turnover management and control.

[0041] The working process of the material turnover robot described above is as follows:

[0042] 1. Silver paste storage and identification: After staff verify their identity through the first identification device, they then identify the code of the silver paste container through the second identification device, and upload information such as the silver paste ID, model, and batch to the MES system. After that, staff place the silver paste container in the storage compartment, and the weight sensor monitors the weight of the silver paste container in real time and uploads the data to the MES system.

[0043] 2. Automated Transportation and Handover: Based on preset tasks and real-time production line data, the robot automatically transports the silver paste to the designated screen printing section and channel. Upon arrival at the designated location, the robot interacts with the machine to complete the handover of the silver paste.

[0044] 3. Weight monitoring and closed-loop control: During the silver paste transfer process, the weight sensor monitors the weight change of the silver paste tank in real time.

[0045] The aforementioned material handling robots enable human-machine interaction, anomaly monitoring, process error prevention, and data visualization during the storage and handling of silver paste, effectively improving work efficiency. They achieve fully automated management of the entire process from storage and transportation to use of silver paste, reducing manual intervention and lowering the rate of operational errors. They also enhance the monitoring and control of silver paste loss by monitoring its weight and status in real time, ensuring its safety and preventing loss during the transfer process. Furthermore, they utilize artificial intelligence technology to alleviate the shortage of human resources, improve production efficiency, and enhance the interactive service experience.

[0046] In this embodiment, the aforementioned first identification device 31 is configured as two units: a face recognition device and a card reader. The face recognition device, based on artificial intelligence technology, identifies a person by analyzing and comparing facial features. The card reader is used to read data from various memory cards or smart cards. Both methods can be used to identify the identity of staff.

[0047] In this embodiment, the second identification device 32 is a barcode scanner. The barcode scanner can read graphic information such as QR codes or barcodes and convert it into computer-readable data. Specifically, the silver paste container 1 is equipped with a QR code or barcode. After scanning the QR code or barcode, the barcode scanner can obtain the code and material information of the silver paste container.

[0048] In this embodiment, the first identification device 31 and / or the second identification device 32 are located at the end of the storage cabinet 3 along its length.

[0049] The first identification device 31 and the second identification device 32 can be located at the same end of the storage cabinet or at different ends. For ease of operation, it is best to place the first identification device 31 and the second identification device 32 close to each other. The ends of the storage cabinet 3 in the longitudinal direction usually have relatively large space, and placing the first identification device and / or the second identification device at this location will not occupy too much storage space inside the storage cabinet.

[0050] In this embodiment, the storage cabinet 3 includes one or two storage units arranged along the width direction of the storage cabinet 3. Each storage unit includes multiple storage layers arranged sequentially along the height direction of the storage cabinet 3. Each storage layer includes multiple storage compartments 33 arranged sequentially along the length direction of the storage cabinet 3. The opening of the storage compartment 33 faces the side of the storage cabinet 3 along the width direction.

[0051] In the above description, storage cabinet 3 can contain one storage unit or two storage units arranged along the width of storage cabinet 3. Each storage unit is internally arranged along the height direction, with multiple storage layers arranged sequentially. This design, with multiple storage layers along the height direction, fully utilizes the vertical space of the storage cabinet, enabling layered storage of items of different heights and improving space utilization. Each storage layer further includes multiple storage compartments 33 arranged sequentially along the length of storage cabinet 3. This layout allows each storage layer to be divided into multiple independent storage spaces, facilitating the categorization and storage of different items and preventing interference and confusion between items. The openings of the storage compartments 33 face the side of storage cabinet 3 along its width direction. This design facilitates access to items from the side of the storage cabinet.

[0052] In this embodiment, the storage compartment 33 is further provided with a tray 37, which is fixed to the weight sensor 34.

[0053] A tray 37 is installed inside the storage compartment 33, and the tray 37 is fixedly mounted on a weight sensor 34. The tray 37 can measure the weight of items placed on it with the help of the weight sensor 34. When the silver paste bucket 1 is placed on the tray 37, the weight sensor 34 can obtain the weight information of the silver paste bucket 1 (including the material inside the bucket) in real time.

[0054] In this embodiment, the edge of the tray 37 is provided with a protruding limiting structure 371. The tray 37 is used to support a single silver paste bucket 1, and the limiting structure 371 restricts the translation of the supported silver paste bucket 1.

[0055] The primary function of tray 37 is to support a single silver paste container 1. This provides a stable platform for the container, allowing it to be stored orderly within the storage compartment 33. The edge of tray 37 is equipped with a raised limiting structure 371, which restricts the translational movement of the supported silver paste container 1. This effectively prevents the container from shifting within the storage compartment, avoiding potential collisions or tipping due to movement. The tray 37 can be freely placed and removed, saving operational time. Figure 4 The middle section is a single-material-bucket structure, meaning that each weight sensor is equipped with a tray and a silver paste cylinder.

[0056] In this embodiment, the storage cabinet 3 further includes an obstacle avoidance sensor 38, which is used to detect obstacles on the robot's walking path. The control system controls the mobile chassis 2 based on the obstacle information detected by the obstacle avoidance sensor 38.

[0057] The obstacle avoidance sensor 38 is used to detect obstacles around the object and provide the device with collision avoidance information. The robot monitors its surrounding environment in real time through the obstacle avoidance sensor 38 to ensure the robot's safety during movement.

[0058] In this embodiment, the two obstacle avoidance sensors 38 are located near the top of the storage cabinet 3 and near both sides of the storage cabinet 3 along the width direction.

[0059] Placing the obstacle avoidance sensor 38 on the top of the storage cabinet 3 allows for better monitoring of the space above and around the cabinet, preventing collisions when the cabinet moves or objects approach from above. Two obstacle avoidance sensors 38 are located on either side of the storage cabinet 3 along its width. This layout effectively monitors the space on both sides of the cabinet's width, forming a relatively comprehensive monitoring area. When objects approach the cabinet from either side, they are detected promptly by the sensors, thus achieving obstacle avoidance.

[0060] In this embodiment, the obstacle avoidance sensor 38 is a lidar.

[0061] LiDAR calculates distance by emitting laser beams and measuring the time it takes for the beam to travel from emission to reflection from an obstacle. It can emit multiple laser beams to create a three-dimensional point cloud map, accurately depicting the shape of the surrounding environment and the location of obstacles.

[0062] The aforementioned material handling robot also includes monitoring and alarm devices. If the material weight changes during the transfer process, the system will activate monitoring, issue an alarm, and suspend other related operations to ensure the safety of the silver paste transfer process.

[0063] The material handling robot provided in this application has broad market prospects and application value. It can effectively solve the problems in the storage and turnover of silver paste in the solar cell industry, preventing loss during turnover and meeting the photovoltaic industry's strict requirements for silver paste consumption control. Simultaneously, the robot can automatically complete the storage and turnover of silver paste without human intervention, greatly improving production efficiency and meeting the demand for highly efficient automated equipment in the field of robotics. Furthermore, this invention can also be applied to other fields requiring high-precision material management, such as electronics manufacturing and chemical industries.

[0064] Example 2: See Figure 5 As shown, this is one embodiment of the material handling robot of the present invention.

[0065] The rest is the same as in Embodiment 1, except that each weight sensor 34 is provided with a pad 39, and each pad 39 is provided with two trays 37. Figure 5 It has a dual-tank structure, meaning that each weight sensor has two trays and two silver paste cylinders.

[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
