The beat calculation of the power robot is crucial to the efficiency and capacity of the production line. The following are the specific steps on how to calculate the beat of the power robot:
1. Clarify production goals
- Production demand : First, we need to clarify the daily or hourly production plan. For example, if the production target is to produce 200 products per hour, the cycle time (T) of each product can be calculated by the formula:T=3600SecondHourly outputT=Hourly output3600 secondsFor example, the cycle time for 200 products per hour is:T=3600200=18SecondT=2003600=18 seconds This means that the completion time of each product should not exceed 18 seconds in theory.
2. Refine the work process
- Action decomposition : Decompose the action of the power manipulator into multiple steps, such as grasping, moving, positioning, releasing, etc.
- Single action time : Calculate the time required for each action separately. This time depends on the robot’s speed, path length, acceleration, etc. For example:If each action takes the above time, the total operation time of a single cycle is:Total operation time=2+5+1+2=10SecondTotal operation time=2+5+1+2=10 seconds
- Crawl time: 2 seconds
- Moving time: 5 seconds
- Positioning time: 1 second
- Release time: 2 seconds
- Buffer time and waiting time : It is necessary to take into account possible buffer time or waiting time, such as the waiting time for the workpiece conveyor to arrive.
3. Coordinate with other devices
- Production line beat balance : Power manipulators usually work in conjunction with other equipment such as processing machines, conveyor belts, etc. When calculating the beat, it is necessary to ensure that the operation of the power manipulator matches the beat of other equipment. For example, if the processing machine completes an operation every 20 seconds, the beat of the power manipulator should be adjusted to less than or equal to 20 seconds to avoid bottlenecks.
4. Parameter adjustment and optimization
- Optimize motion parameters : If the calculated total operation time exceeds the predetermined cycle target, for example, more than 18 seconds, you can optimize it by the following measures:
- Improve movement speed : Increase the movement speed of the power manipulator and reduce the time required for each operation.
- Optimize path : adjust the working path of the robot to reduce unnecessary moving distance.
- Reduce waiting time : Reduce the waiting and buffering time of the robot to ensure efficient coordination with other equipment.
5. Actual adjustment and verification
- In actual production, adjustments need to be made based on equipment performance and production site conditions, and the parameters of the robot need to be verified and fine-tuned to ensure that it achieves the optimal rhythm.
Summarize
The calculation of the robot’s beat needs to comprehensively consider the production goals, operation process and overall coordination of the production line. Through careful analysis and adjustment, the robot’s beat can be ensured to be within a reasonable range, thereby improving production efficiency and overall capacity.
