In the mechanical market, all kinds of robots readily available. Potential buyers can use some guidelines to make informed decisions. To compare effectively different things, start with the basics; by understanding the basics, you can make informed choices when choosing a manipulator.
How big itinerary?
The distance traveled by the manipulator is a well-known stroke whose size is related to the size of the part, the descent position and the shape of the machine. For the sake of simplicity, this distance is usually defined by three axes: Our company uses walking, front and back, up and down.
Walking: also known as horizontal travel, the size of the back and forth travel depends on whether the robot is on the side of the machine or in the back of the parts down. The parts that make use of this stroke are just to skip the machine.
Before and after: also known as the lead-in trip, the size and thickness of the part. For example, in order to manipulate a bucket, to extend the manipulator, and the barrel pulled out from the mold, you need enough travel.
Up and down: also known as vertical travel, is determined by the height of the machine and the descent height required, that is, the manipulator must be tall enough so that the part can skip the machine and be low enough to be reasonably well off the ground The height of the parts down.
The easiest way to determine the desired trip is to draw a layout. The layout not only identifies each trip, but also identifies important issues on the floor plan, such as accessories, support columns and void areas.
Robot manipulation of multiple items?
The payload is the weight the robot can handle and is defined as follows:
Payload = part weight + arm end tool weight
Component weights are often known for a particular purpose; however, the arm end tool is not the case, and the arm end tool weight is based on the fixture size.
Torque is more important than payload. Torque is defined as the tendency of a force to twist and rotate about one axis as a function of the payload's distance from the robot's pivot point. To ensure that the manipulator can manipulate the components, compare the actual torque with the available torque that the manipulator can support.
How to evaluate performance?
Robotic performance is often assumed at the rate of peak. However, this is not all, unless we know that the acceleration shows the speed of two robots, one with a peak velocity of 4m / s and the other of 3m / s. One might infer that the "fastest" robot is the one with the higher speed spikes. However, both robots can walk the same distance of 2800 mm in 1 second. This is possible because robots with lower peak rates have a higher acceleration (45 m / s2) than robots with higher peak rates, and 13.3 m / s2 for the latter. It is more useful for the robot to spend a particular distance on a walk.
Is robot easy to use?
Features that contribute to user-friendly operation include: control panel with graphical user interface, intuitive touch screen and pedestal. With the hand-held console, operators can choose to program the robot or use the system's main control board mounted on the machine.
The type of control system in place also affects availability. The robot controller integrated with the injection molding machine controller has a common display screen for more convenience and a common robot controller for minimal interruption of communication. Other features include preprogrammed templates that simplify robot programming, and remote diagnostics that enable molders to contact their online service engineers directly.
Look for digital components at the top, such as servo motors and digitally-driven computer controllers. Like any mechanism, the part will fail at some point, so check the shelf life of the robot. The shelf life of different robots slightly different. When evaluating a shelf life, consider a number of wear items: belts, sleeves, filters, switches, sensors, fuel tanks and more. Therefore, the three-year strategy may not necessarily better than the one-year strategy.
How safe is a robot?
Robot belongs to the standard of ANSI B151.27-1994, which controls the robot of horizontal injection molding machine and is a sub-standard of Common Industrial Standard ANSI / RIAR15.06-1999.
From the security point of view, there are a lot of places to be concerned about. They include restrictions on the robot's working space, the installation of mechanical stops, vertical drop safety, and the use of three switches. Make sure that the robot meets all practical safety regulations.
