Dental chairs serve two functions. The primary is to make sure that sufferers are as snug as attainable in a hectic atmosphere. The second is to place sufferers, lighting and devices in order that dentists and hygienists can carry out their duties precisely, effectively and ergonomically.
PeyMar, a producer of dental chairs based mostly in Mexico Metropolis, has been efficiently discovering that steadiness since 2014.

To fabricate the chairs, the corporate should weld quite a lot of steel frames and elements. The welding course of posed a number of challenges for the corporate, together with:
- Inefficiency: Conventional welding setups required a number of operators and machines for various workstations, resulting in bottlenecks and elevated cycle occasions.
- Area constraints: The store flooring had restricted house, making it troublesome to accommodate a number of welding stations and gear.
- Excessive labor prices: Using a number of staff for various welding duties elevated prices and administration complexity.
- Integration points: PeyMar engineers struggled to combine current robots with varied welding methods and equipment, limiting flexibility and customization.
To deal with these challenges, engineers developed a customized system that consists of a Dobot CR20A collaborative robotic mounted to a linear rail and geared up with a welder from Miller Electrical Manufacturing LLC. This configuration allows a single robotic arm to function throughout six welding stations repeatedly, requiring just one worker to handle the method.

Now, the cobot can weld one element whereas the operator replaces the finished half, minimizing downtime and maximizing output. By utilizing one robotic throughout a number of stations, PeyMar made probably the most of its restricted flooring house. It additionally diminished prices for labor, capital funding and upkeep.
The CR20A can carry a most payload of 20 kilograms, and it has a most attain of 1,700 millimeters. The CR20A has a dual-channel end-effector design, which might straight connect with a number of finish instruments. It additionally incorporates a visible standing indicator on the base for intuitive recognition of working standing.
With a complicated movement management algorithm, the CR20A operates extra stably, with residual vibrations diminished by 50 % throughout high-speed emergency stops.

Cobot Specifics
Dobot’s new CRA collection of cobots have been designed for high-speed, security and stability. Joint pace has been elevated to 223 levels per second, which is among the many quickest within the business. This enchancment permits for a wider vary of purposes and reduces cycle time for frequent duties, akin to materials dealing with, by as a lot as 25 %.
An EtherCAT bus is utilized by the joint servomotor, offering an unlimited bandwidth of a whole bunch of megabits and a joint response pace within the millisecond vary. This enhances the cobot’s pace and trajectory smoothness.
Every cobot is calibrated with a laser calibration system, making certain an absolute positioning accuracy of beneath 0.4 millimeter. This allows the robotic to deal with high-precision meeting duties.
The cobot is ruled by a stand-alone security controller that’s rated at PLd Cat.3. It options greater than 20 security features, and it’s licensed to ISO 13849-1, ISO 10218-1, and ISO/TS 15066. With correct danger evaluation, the cobot can collaborate with individuals with out the necessity for added fencing.
Within the occasion of an influence outage, the robotic engages an electromagnetic brake inside 18 milliseconds. This ensures place retention inside 1 millimeter and safeguards towards gear or product injury.

The cobot will be programmed for “virtual fencing,” enabling engineers to plan security measures tailor-made to their distinctive manufacturing settings. As an choice, the cobot will be geared up with a “safety skin” that immediately stops the cobot if it ought to contact an individual. This ensures optimum security at each stage of the meeting course of.
The cobots have 24 DI and DO interfaces, supporting each PNP and NPN switching. They’re additionally configured with greater than 30 features for robotic management and standing suggestions, offering comfort and adaptability for integration and management.
Moreover, the cobots come geared up with customary communication strategies like Modbus TCP/RTU, EtherNet/IP and Profinet. This aids integration with PLCs, HMIs, and different gadgets, eliminating worries about communication protocol compatibility.
DobotStudio Professional software program simplifies the duty of programming the cobot. Programming is completed with intuitive and user-friendly “blocks.” By combining varied blocks, engineers can simply create versatile packages. On the similar time, expert builders can design intricate packages and handle superior purposes via the availability of adaptable LUA script programming.

A variety of plug-in equipment is out there, together with grippers, drive sensors, and 2D and 3D imaginative and prescient. By utilizing the ready-to-use APIs from the plugins, engineers can develop purposes in a brief span of time.
A spread of software packages is out there, together with welding, palletizing and machine tending. By adjusting parameters, packages will be simply created.
A log allows engineers to entry historic standing, operation information, and parameter modification info. This permits for swift drawback identification and minimizes downtime.
Engineers can leverage offline programming to execute, debug and validate packages with out being related to the robotic. The cobot additionally helps entry by way of laptop, pill or train pendant. Each wired and wi-fi connection strategies can be found.
