Linear modules are automated mechanical instruments, less flexible than manual machines. Therefore, in practical work, it's crucial to accurately control changes in their precision. This necessitates using the methods mentioned above for measuring linear modules. Furthermore, selecting high-quality linear modules is essential to maximize their basic accuracy. For industrial production, linear modules don't need to be designed like works of art; functionality is sufficient. Beyond functionality, space utilization must be minimized, meaning a compact design is required. The overall size of the linear module should be moderate, while also ensuring sufficient load-bearing capacity.
The parallelism of the workpiece is checked by placing a standard ruler on the platform of the high-quality and durable linear module, and measuring the maximum range of movement of the slider within the experimental indicator. The maximum difference between the readings within the range of movement of the servo electric cylinder is the measured value. High precision and strong load-bearing capacity are essential characteristics of mechanical linear modules. Compared with manual labor, a significant advantage of machinery is its much higher precision, which does not change significantly over time. This ensures good performance on industrial production lines, reducing labor costs. The load-bearing capacity of the linear motor can also be customized according to the specific needs of each enterprise. If the product requiring the linear module is heavy, materials with better load-bearing capacity can be used for production. Positioning accuracy is measured by using its maximum stroke as the reference length, and then expressing it as the absolute value of the maximum error between the distance moved from the reference position to the actual value and the command value.
Multi-joint robotic arms: These are characterized by their agility, low inertia, versatility, and miniature electric arc grippers. They can grasp workpieces close to the base and navigate around obstacles between the machine body and the workpiece. With increasing production demands, higher requirements are being placed on the agility, positioning accuracy, and workspace of multi-joint arms. However, linear modules are ultimately just machines, and the vibrations generated during long-term operation can alter their accuracy. Therefore, single-axis arms require constant monitoring to ensure their accuracy remains within the initially set range. They can continue operation for one cycle even in the event of a gas outage, with an alarm to alert the operator. Orthogonal robotic arms can work with various non-standard grippers, while cable-assisted robotic arms can lift workpieces of various shapes. They can be fixed to the ground or suspended for fixed use; rail-mounted installation is not possible.
