Typically, linear robotics are divided into three main categories based on their application and installation features.
Linear Modules
The linear module is a compact transporting system. It presents motion control or automation as a pre-assembled product. Usually, linear modules combine a motor, guide rail, and drive system all in one. This compact design makes installation and implementation of linear motion easier for users. Linear modules have various sizes and types of strokes. Buyers can select them to match specific project needs.
Linear Giant Robots
Usually, larger productions need to use giant linear robots because of their heavy capacity. These big robots are great at moving and positioning larger goods or parts. They feature heavier guides and belts compared to small robots, which allows linear giant robots to offer stable and strong support for bigger loads. Moreover, some linear giant robots are modularized so that they can meet diverse space or product demands in the industry.
Multi-axis Robots
Multi-axis linear robots usually combine linear and rotary motion redundantly. This results in great flexibility. They characteristically comprise a frameless motor with low inertia and a tubular external rotor. The motion chain includes a belt and a pulley. The robots can travel along multiple axes. Some models are designed to be dust-proof or water-proof with a high IP rating, which means they can work well even in harsher environments. Additionally, they possess a high payload capacity and can perform heavier loads and rapid acceleration effectively.
To get the most out of the linear robot, it's best to understand the impact of each component on machine performance. When handling these parts, it's best to use mechanical arms or tweezers designed for delicate work, so things like the fragile Cartesian component or the smaller items like the ball bearings aren't damaged during setup or maintenance. Power Supply Unit (PSU) requirements are important too: make sure they fit within specified voltage ranges by checking other compatible parts' specifications before purchasing any additional power sources like batteries or external PSUs that have not come with the original package, as they may not be safe for use together with this system.
Usually, the PSU output takes around 24V but could vary based on what type of servo motors are being used. The controlling board of these robots needs to work seamlessly with their chosen servos by supporting pulse widths and having the right size connectors for easy plug-and-play capability. It should also have features like advanced motion control algorithms so more complex actions become possible without needing other extra devices to help do them better. If an external device is meant to send commands or receive data in a more distant place than just a local indoor area, then communication ports become really important, too, especially if we're talking about using something like a Wi-Fi router instead of just Wi-Fi directly built inside the unit. Regular inspection helps us find early signs of damage, like dirt build-up, which can block the tracks' smooth running over time if not cleaned away. Pay attention, too, to those little gears and bearings since they transfer movement throughout the whole track system; lubricate them regularly to keep everything working well together in unison smoothly, just like the day it was first installed and used for the very first time. Routine checks must include tightly securing parts, cleaning out dirt or debris inside while making sure nothing else has gotten stuck and checking all lubricated spots, especially the ones where oil or grease is put on a regular basis.
With the development of technology, the application scenarios of linear robotics are expanding continuously. Nowadays, they are not limited to industrial production lines. Here are some familiar and emerging application scenarios for linear robotics.
Automotive Manufacturing
As a representative field of linear robotic application, automotive manufacturing needs high-precision and high-efficiency assembly and production. Linear robots are used to install and assemble parts such as auto glass, dashboards, car doors, car interiors, etc. The use of linear robotics can ensure the uniformity and consistency of automotive product quality. Additionally, automotive manufacturing has a high requirement for the speed of assembly lines. Robots can operate more quickly and stably than manual operations, increasing linear automotive manufacturing productivity.
Food Processing
The food industry is facing challenges like increasing production demand, quality assurance, and regulatory compliance. Linear robots are helping to address these issues by providing precision handling, packaging, and sorting capabilities. For example, they can delicately and safely pick and place bakery products, fruits, and vegetables, dairy products, meat, and more. Linear robotics can replace human hands to rapidly pick and package food items. They can also be used to sort and grade food according to quality. Using linear robotics in food processing can reduce labor costs, enhance production efficiency, and ensure food safety and hygiene.
Logistics Automation
Linear robots play an important role in the automation of logistics. Whether it is warehousing, sorting, or packaging, linear robots can be used to achieve automation and intelligence, thus improving efficiency and accuracy. For instance, linear robotic systems can automatically store and retrieve items in warehouses, reducing manual intervention. They can also sort packages based on their destinations and dimensions, streamlining the distribution process. Linear robotics can replace human workers on assembly lines to deal with packages. They can move packages from one place to another, for example, from the assembly line to a storage space. The application of linear robotics in logistics can achieve the goals of fast delivery, automated sorting, and intelligent warehousing.
Choosing the right linear motion module robotic system for a business's needs requires careful consideration of several factors. The following decision-making tips will help buyers select a linear motion module that fits their specific requirements:
Needs Assessment
Users should start by assessing their specific needs. They should consider factors like the weight and size of the payload, speed and acceleration requirements, travel distance, and the precision and repeatability needed for the application. This initial evaluation will help them identify the crucial specifications and features they need in a linear robotic system.
Payload Capacity and Size
It is important to ensure that the linear robot chosen has a suitable payload capacity for the items to be moved. Additionally, the dimensions of the robot should fit the available space in the work environment.
Speed and Acceleration
Consider the required speed and acceleration of the application. Choose a linear robot that can provide the necessary speed for efficient operation. It's also important to note that the acceleration and deceleration characteristics of the linear robot can impact productivity.
Precision and Repeatability
Linear robotics comes in various levels of precision and repeatability. Depending on the application, whether it is assembly, pick-and-place, or another task, users should choose a linear robot with the desired accuracy to ensure proper functioning and reliability.
Communication and Integration
The chosen linear robot should have the necessary communication protocols for easy integration with existing systems, such as PLCs, sensors, and other automation components. Make sure that there are no compatibility issues that may cause delays and additional costs during installation.
Supplier Selection
After considering all the above factors, take time to research potential suppliers of the linear robot. Check the supplier’s reputation, product quality, and customer support services. It's also advisable to read customer reviews and testimonials to learn more about a supplier before finally choosing them.
