This article will deeply explore the technical mysteries, diverse application scenarios, significant advantages, and future development trends of boxing robots, bringing you a comprehensive understanding of the charm of this intelligent equipment.
The mechanical structure of a boxing robot is like its solid "skeleton", which is the basis for achieving efficient boxing operations. Common boxing palletizer equipment mostly adopt parallel robot structures or articulated robot structures.
• Parallel Robot Structure: Represented by Delta robots, it consists of a fixed platform, a moving platform, and multiple parallel kinematic chains connecting them. This structure has the characteristics of high speed, high precision, and high rigidity. In the boxing process, Delta robots can rely on their lightweight and flexible mechanical arms to move quickly in the working space, accurately grasp products and place them into packaging boxes. For example, in the potato chip packaging line of the food industry, Delta robots can quickly and neatly pack bagged potato chips into cartons, with an action beat of dozens of times per minute or even higher, greatly improving the boxing efficiency. At the same time, due to the good rigidity of its mechanical structure, it can remain stable during high-speed movement, ensuring the accuracy of grasping and placing products, and effectively avoiding product collision and damage.
• Articulated Robot Structure: Usually connected by multiple rotating joints, similar to a human arm, it has high flexibility and a large working space. This type of robot can realize complex trajectory planning through the coordinated movement of different joints, adapting to the boxing needs of products of various shapes and sizes. In the boxing operations of electronic and electrical products, articulated robots can easily handle the grasping and boxing tasks of products such as circuit boards and components of different specifications. It can flexibly adjust the movement path of the mechanical arm according to the position and posture of the product, and accurately place the product in the designated position of the packaging box, showing excellent flexibility and adaptability.
To enable the mechanical structure to move accurately according to the predetermined trajectory and speed, boxing robots are equipped with advanced drive and transmission systems.
• Drive System: Servo motors are mainly used as the power source. Servo motors have the advantages of fast response speed, high control precision, and stable torque. Through the precise pulse signals sent by the controller, the servo motor can quickly and accurately adjust the rotation speed and angle, thereby realizing high-speed and high-precision motion control of the mechanical arm. In the boxing process, when the robot needs to quickly grasp and place products, the servo motor can reach the set speed in a very short time, making the mechanical arm move to the target position quickly and stop immediately after reaching the position, ensuring the accuracy of grasping and placing actions. For example, in the medicine box boxing operation in the pharmaceutical industry, the mechanical arm driven by the servo motor can neatly stack the medicine boxes in the packaging box with extremely high precision, meeting the strict requirements of pharmaceutical packaging for precision.
• Transmission System: Common transmission methods include gear transmission, synchronous belt transmission, and ball screw transmission. Gear transmission has the advantages of high transmission efficiency, compact structure, and large transmission torque, and is often used in joint parts that require large torque output; synchronous belt transmission has the characteristics of stable transmission, low noise, and relatively low cost, and is suitable for transmission links with high requirements for motion precision and small load; ball screw transmission can convert rotary motion into linear motion or linear motion into rotary motion, with high precision, high rigidity, and high efficiency, and is often used to realize the linear motion of the mechanical arm. These transmission methods cooperate with each other to efficiently and accurately transmit the power of the servo motor to various parts of the mechanical structure, ensuring that the robot can operate stably and reliably.
The intelligent control system is the "brain" of the boxing robot, responsible for commanding the robot to complete various complex boxing tasks. It mainly includes hardware control system and software control system.
• Hardware Control System: It takes industrial controllers as the core, such as programmable logic controllers (PLC) and motion controllers. These controllers obtain real-time information such as the robot's motion state, product position, and posture through various sensors, and issue control commands to the servo motors and other actuators according to preset programs and algorithms to achieve precise control of the robot's motion. For example, through encoders installed at the joints of the mechanical arm, the rotation angle and speed of the joints can be monitored in real-time, and this information can be fed back to the controller. The controller adjusts the output of the servo motor according to the feedback information to ensure that the mechanical arm moves according to the predetermined trajectory. At the same time, pressure sensors, vision sensors, etc. can also be used to obtain product-related information, further improving the operation accuracy and reliability of the robot.
• Software Control System: It is the key to realizing the intelligent operation of the robot. It includes functional modules such as robot motion planning algorithm, task scheduling algorithm, and human-computer interaction interface. The robot motion planning algorithm can quickly generate the optimal motion trajectory according to the product's position, posture, and the size and position of the packaging box, enabling the robot to complete the grasping and boxing tasks in the shortest time and with the most reasonable path. The task scheduling algorithm can reasonably arrange the robot's work tasks according to the product flow and boxing demand on the production line, improving production efficiency. The human-computer interaction interface provides an intuitive and convenient operation platform for operators. Operators can set parameters, issue tasks, monitor the status of the robot through the touch screen or console, and at the same time, can view the robot's operation data and fault information in real-time, facilitating timely maintenance and adjustment.
In the boxing process, accurately identifying the position, posture, and type of products is the key to ensuring the quality and efficiency of boxing. Visual recognition and positioning technology endow boxing robots with "insight", enabling them to quickly and accurately perceive surrounding environmental information.
• Visual Recognition System: It mainly consists of industrial cameras, lenses, light sources, and image processing software. Industrial cameras collect image information of products and packaging boxes through lenses and transmit them to image processing software. The image processing software uses advanced image recognition algorithms to analyze and process the collected images, identify the shape, size, color, and other characteristics of the product, as well as the position and posture information of the product on the conveyor belt. For example, in the biscuit boxing operation in the food industry, the visual recognition system can quickly and accurately identify biscuits of different shapes and flavors, and plan the best grasping path for the robot according to their position and posture information.
• Positioning Technology: Combined with the information obtained by the visual recognition system, the position coordinates of products and packaging boxes in three-dimensional space are accurately calculated through coordinate system conversion and spatial positioning algorithms. The robot adjusts the motion trajectory of the mechanical arm according to these coordinate information to realize accurate grasping and placement of products. At the same time, visual recognition and positioning technology can also conduct quality inspection on products, such as detecting whether products are defective and whether packaging is intact, to ensure that the products entering the packaging box meet quality standards. For example, in the boxing process of electronic products, the vision system can detect whether the pins of electronic components are bent and whether the welding is firm, and timely reject unqualified products to ensure product quality.
