Automatic pick and place robot

Types of Automatic Pick and Place Robots

Automatic pick and place robots come in various types, each designed for specific applications and requirements. Here are some of the most common ones:

• Cartesian Robots

  These robots have a rectangular coordinate system that moves objects along linear paths in the X, Y, and Z directions. They offer high precision, flexibility, and easy programming, making them suitable for many pick and place applications.

• Articulated Robots

  Articulated robots have a human-like arm with rotational joints that provide a full range of motion. This design enables them to handle complex pick and place tasks like product assembly and packaging. In addition, they can work with items from different angles and positions quickly and precisely.

• SCARA Robots

  Selective Compliance Assembly Robot Arm (SCARA) robots have parallel arms that allow for flexibility in the horizontal plane while remaining rigid in the vertical direction. They excel in high-speed and high-accuracy applications such as electronic component assembly, sorting, and packaging.

• Cylindrical Robots

  Cylindrical robots have a circular or cylindrical coordinate system. They consist of a fixed cylindrical arm and a vertical sliding section. These robots offer a high load-carrying capacity and are suitable for handling heavy objects in pick and place operations.

• Delta Robots

  Delta robots are made with three or more parallelogram-like structures that are all connected to a common base. The fixed and movable points create a triangular mechanism that allows for high-speed motion and accuracy. Delta robots are suitable for handling lightweight objects quickly and with high precision, especially in packaging and sorting applications.

• Pick-and-Place Gantry Robots

  These machines, which use perpendicular rails to form a gantry system, slide along the rails to pick and place stuff. They are frequently employed in conjunction with linear motors to move goods in assembly lines quickly and precisely.

• Mobile Pick and Place Robots

  Mobile robots have the ability to move freely within their environment. They are equipped with vision systems that enable them to detect and localize objects in their environment. Additionally, the navigation software allows them to plan and execute safe and efficient paths for pick and place operations. These robots are suitable for material handling in dynamic environments such as warehouse automation and retail logistics.

Specification & Maintenance

The capacity of an automatic pick and place robot is usually measured in kilograms. Still, it may differ based on the robot type, structure, motor power, and working environment. For example, delta robots can usually bear 3-6 kg, while articulating robots can handle 6-60 kg. Robots with higher payloads and more flexible joints can also handle heavier goods.

Robot picking and placing tasks consume a lot of energy, so the efficiency of the battery or power supply is crucial. Some robots are equipped with regenerative braking systems, which can convert kinetic energy back into electrical energy during deceleration or braking, recharging the robot's batteries. Most automatic pick and place robots can work for 16 hours of continuous operation, but this depends on their power and battery capacity.

Robots need to be accurate and resistant to dust, moisture, chemicals, and other environmental hazards. Their precision is determined by their joints and the motors that drive them, which also affect how long they last. Many robots now have IP65 or higher ratings, meaning they are suitably dust- and splash-proof for industrial environments.

To maintain a pick and place automaticRobot for a long time:

• Regular inspection: Routine visual inspections focused on component parts, peripheral devices, control systems, etc. to check for loose connections, damaged components, software system malfunctions, etc. If any problems are found, repairs should be made immediately.
• Lubrication: Each movable part of the robot, such as bearings and gears, should be lubricated regularly with a proper type and amount of grease to ensure its stable operation. Note also that excess lubrication should be avoided to prevent dust from being attracted.
• Cleaning: Dust and debris should be removed from the exterior and the robot's internal parts. Special care should be taken to clean optical encoders and sensors to ensure their sensitivity and accuracy.
• Replacement of parts: Pay attention to the wear and tear of parts such as belts, chains, and gripping pads on the robot, replacing them promptly when they are damaged or worn, to avoid slippage in grabbing actions.
• Software upgrades: Regularly check the robot's control system and software for version updates and upgrades to improve its performance and add new functions.

Scenarios

• Manufacturing:

  In the manufacturing industry, the focus is on producing goods and products. Many factories and manufacturing plants implement industrial automation using automatic pick and place robots to increase efficiency. These robots can be used for tasks such as assembling components, Attaching lids on bottles, inserting parts, quality inspection, and even packaging and palletizing finished products, among many other applications. Using automatic pick and place robots in manufacturing ensures that a uniform and higher product standard of quality is maintained.

• Food handling:

  Food-related companies must comply with strict hygiene standards so that the food is safe for consumption. Using automatic pick and place robots helps reduce human contact with the food products. They can easily be integrated with other food processing machinery, making them an ideal choice for food-related industries. The only requirement is that the robots must be made of food-grade materials, in line with all the other rules and regulations of the industry.

• Healthcare:

  Automatic pick and place robots can be used in healthcare-related industries with modification and customization. They can help pharmacists automate picking medications and assist healthcare facilities with inventory management. Also, these robots can support research labs by handling samples, reagents, and tools, thereby improving precision and reducing the risk of human error.

• If robotics:

  Robotic picking systems can be used in e-commerce warehouses to automate the picking and packing process for online orders. They can identify and pick products from storage shelves, pack them into boxes, and label them for shipment, all at high speeds and with great accuracy. This helps boost order fulfillment efficiency and reduce labor costs.
