Kunshan Manipulator Acquisition Strategy
In the machinery market, all kinds of manipulators are readily available. Potential buyers can use some guidelines to make an informed decision. To compare different things usefully, start with the basic elements; by understanding the basics, you can make wise choices when choosing a robot.
How big is the itinerary?
The walking interval of the manipulator is the well-known stroke, and its size is related to the size of the part, the descending direction and the shape of the machine. For simplicity, this interval is generally defined in terms of three axes: our company uses travel, front and back, and up and down indications.
Traveling: also called horizontal travel, the size of the back and forth movement depends on whether the manipulator puts the parts down on the side of the machine or behind the machine. Parts of this type of travel are used only to skip the machine.
Front and rear: Also called the drawing stroke, its size is related to the thickness of the part. For example, in order to operate a bucket, it is necessary to extend the manipulator and pull the bucket out of the mold, which requires a satisfactory stroke.
Up and down: Also called straight stroke, it is determined by the height of the machine and the required drop height, that is to say, the height that the manipulator must meet so that the parts can jump over the machine, but also meet the low, and then can be reasonable off the ground Put down the parts at the height of the
The easiest way to confirm the required itinerary is to draw a layout diagram. The layout not only confirms each itinerary, but also confirms important items on the floor plan, such as auxiliary equipment, support columns, and empty areas.
Manipulator handles multiple items
The useful load is the component that the manipulator can handle, and is defined as follows:
Useful load = component component + arm end tool component
The component weight is often known for a specific purpose; however, this is not the case with end-of-arm tools. The weight of end-of-arm tools depends on the size of the fixture.
Torque is more important than useful load. The definition of torque is the tendency of a force to change and rotate around an axis, and it is a function of the useful load and the interval between the pivot point of the manipulator. To ensure that the manipulator can operate parts, compare the actual torque with the available torque that the manipulator can support.
How to comment on features?
Manipulator functions are often assumed based on the peak rate. However, this is not all, unless we know that the acceleration shows the speed of two manipulators, one with a peak speed of 4m/s and the other at 3m/s. One might speculate that the "fastest" manipulator is the one with the higher peak velocity. However, the two manipulators can walk the same interval of 2800mm within 1 second. This is possible because a manipulator with a lower peak velocity has a higher acceleration (45m/s2) than a manipulator with a higher peak velocity, which is 13.3m/s2. The time it takes for the manipulator to walk a certain interval is more useful.
Is the robot easy to use?
Features that contribute to user-friendly operation include: a control panel with a graphical user interface, an intuitive touch screen, and a suspension button station. Using the handheld console, the operator can choose to program the manipulator, or use the system main control board installed on the machine.
The type of control system in the proper position also affects usability. The manipulator controller summed up with the injection molding machine controller enjoys a more convenient general display screen and a general manipulator controller with the least communication interruption. Other features include pre-programmed templates that simplify manipulator programming, and remote diagnostic capabilities that enable molding companies to directly contact online service engineers.
Look for digital components at the top, such as computer controllers with servo motors and digital drives. Like any mechanism, parts will fail at certain points, so check the shelf life of the manipulator. The shelf life of different manipulators is slightly different. When evaluating a shelf life, a series of wear items should be considered: belts, casings, filters, switches, sensors, cylinders, etc. Therefore, a three-year strategy may not be better than a one-year strategy.
How safe is the manipulator?
The manipulator belongs to the scope of the ANSI B151.27-1994 standard, which governs the manipulator of the horizontal injection molding machine and is a substandard of the general industry standard ANSI/RIAR15.06-1999.
From the perspective of safety, there are a lot of things that need attention. They include the limitation of the manipulator's working space, the device of mechanical limit equipment, the safety maintenance of straight down, and the use of three-position switches. Make sure that the manipulator meets all useful safety standards.
how's the price?
The capital cost of the robot is as important as the financial impact of the robot on the entire system. The savings associated with shorter downtime or faster cycle times can be real. According to the actual situation of the industry, for example, a factory with 6000 hours of production can achieve significant savings:
The downtime of the manipulator of the 1,800-ton injection molding machine is reduced by 1%, which will save up to 50,000 yuan in the molding industry every year.
The 200-ton injection molding machine with a cycle time of 10 seconds will save 80,000 yuan per year for every 0.5 second reduction.
Finally, when making an acquisition decision, consider that the function, reliability, safety and cost of the manipulator play an important role in the operation of the entire system, so that the manipulator you choose will be more reasonable.
