Technical support and selection

Buying the wrong robot wastes not only equipment costs but also the time and opportunity costs of production line upgrades. Before selecting a model, we clarify your requirements: load, reach, takt time, accuracy, installation space—none can be neglected.

What parameters should be set when choosing a model?

Many companies buy robots with the idea of "the one used in someone else's workshop is great, so I'll get one too," but the result is either insufficient load, slow beats, or insufficient installation space. Essentially, the selection involves solving a constraint equation with six core variables: load, boom (working radius), cycle time, repeatability, protection level, and installation method. The load is not only the weight of the workpiece, but also the self-weight of the end effectors (fixtures, suction cups, welding guns, glue guns), with a safety margin remaining; The arm reach should cover all work points, and attention should be paid to how wrist posture affects the actual reachable range. It's not enough to just draw a circle with the nominal arm span; The beat must be calculated based on the actual action cycle, including pick-up, place, movement, and positioning waiting time; theoretical maximum speed is basically not reached; Accuracy depends on whether it is repeatable positioning accuracy or absolute positioning accuracy; most applications only care about the former; Protection levels are critical constraints in environments such as welding, spraying, cleaning, food, and casting; Installation methods include floor, inverted, wall-mounted, and rail, directly affecting the reachable range and civil engineering costs. With these six criteria, the range of models is basically narrowed down to just a few.

How can you avoid buying the wrong load and reach?

The most common mistake in load selection is looking only at the net weight of the workpiece. The correct algorithm is: robot rated load ≥ workpiece weight + end effector weight + additional cable and air tube weight, with a margin of more than 20%. At the same time, check the inertia — the allowable inertia of the robot's wrist is a commonly overlooked limit. When the fixture is long and heavy, even if the total weight does not exceed the limit, excessive inertia can cause shaking, reduced accuracy, or even alarms. When choosing a reach, consider the effective working range rather than the maximum radius: near the base of the body and at the edges near the maximum radius, the robot's usable posture and load capacity will decrease, and the actual stable operation is often in a circular area. Our approach is to perform a reachability verification using your workpiece dimensions, workstation layout, and pick-and-place points, confirming that the posture does not exceed limits and does not interfere with surrounding equipment, before determining the model.

How to calculate beat time and production capacity?

The beat determines how many robots are needed and whether automation is worth it. The calculation method breaks down the entire action cycle as: pickup, lifting, horizontal movement, descent, positioning, placement, return. Each segment takes time based on actual displacement and allowable acceleration/deceleration, plus fixture action, signal interaction, and upstream and downstream waiting times. Manufacturer samples list the maximum speed and standard cycle time for each shaft, which are numbers under ideal attitude and load; actual operating conditions usually require discounts. If a single machine cannot meet the beat rate, there are two options: increase robot specifications (faster models), or increase workstations and robot numbers in parallel. We will include the calculation process and assumptions in the report, which you can review yourself, rather than just giving a "should be enough" statement.

What's in the diagnostic report?

Production line automation diagnostics are not just a skimming view; the output is an actionable report. The content includes: current status description (manual configuration for each process, bottleneck workstations, existing equipment interface status), automation feasibility assessment (which processes are suitable for robots, input-output ratio, and which processes are temporarily not worth modifying), model recommendations (including comparison of load reach accuracy with candidate models), layout and interference analysis (installation location, reachability, safe distance from surrounding equipment), cycle time calculation (cycle time decomposition and capacity forecasting), risk warnings (consistency of workpieces, incoming material stability, Requirements for personnel skills), and step-by-step implementation recommendations (which workstation to change first, how to retain the rollback plan). The report provides conclusions and evidence, not a bunch of templates and clichés. You can use them to compare prices with other suppliers.

What we don't do

There are a few points to clarify in advance to avoid any gaps between expectations. First, we do not make unfounded promises: the benefits of automation transformation depend on many variables such as incoming material consistency, product replacement frequency, and personnel cooperation. We provide the basis and prerequisites for calculations, but do not guarantee "guaranteed returns." Second, we don't sell products: the diagnostic conclusion might be that robots are not recommended—for example, if the product batch is too small, the model changes too quickly, or the workpiece consistency is too poor. In such cases, forcing robots on the platform would actually increase costs, and we will explain this truthfully. Third, we do not undertake tasks beyond our capabilities: for projects involving full line planning, MES integration, and non-standard special machine design, we will clarify boundaries and recommend suitable partners. The value of diagnostic consultations lies in helping you spend money where it is, rather than facilitating a single device sale.
