Robot Mounting Jig for Motor Brake Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods face challenges in mounting electric apparatuses, such as motors, to a given position using a robot, especially when non-exciting operation type electromagnetic brakes are engaged, preventing the motor's output shaft from rotating and hindering alignment of fixing bolt holes with screw holes, especially in fixed product robot attitudes.
Innovation Solution
An electric apparatus mounting device and method involving a robot side contact jig and an electric apparatus side contact jig, where the robot side contact is connected to a power source to unlock the electromagnetic brake, allowing the motor to be rotated and positioned correctly, using a detachable contact system for the motor side contact jig and a controller for power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-exciting operation type electromagnetic brake is provided in the servo motor to prevent runaway, then safety is improved, but the motor output shaft cannot be rotated when power is not supplied, making it impossible to align fixing bolt holes
Solution Approach 1:
The electromagnetic brake is activated in advance during the motor conveyance process to maintain safety, and is deactivated only when the gear engagement is completed, allowing the motor main body to be rotated for alignment without compromising overall safety
Solution Approach 2:
The electromagnetic brake state is dynamically changed from locked to unlocked based on the mounting process stage, enabling the motor main body to be rotated when needed while maintaining safety during conveyance
2Manufacturing precision
If the attitude of the product robot is firmly fixed during production, then positioning precision is improved, but the fixing bolt hole position cannot be aligned with the screw hole on the robot side
Solution Approach 1:
The gear engagement is completed in advance while the product robot attitude is fixed, ensuring positioning precision is maintained, and then the electromagnetic brake is deactivated to allow motor main body rotation for hole alignment
3Ease of operation
If the motor main body is rotated to align fixing bolt holes, then ease of operation is improved, but excessive force may be applied to the gear on the drive shaft side
Solution Approach 1:
The gear engagement is completed beforehand before rotating the motor main body, ensuring that the gears are properly meshed and can withstand the rotational force without damage
Solution Approach 2:
The electromagnetic brake is deactivated temporarily during the rotation operation to enable motor main body rotation, then reactivated after alignment to prevent excessive force on the gears
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables unhindered conveying and mounting of electric apparatuses by unlocking the electromagnetic brake, allowing the motor to be rotated and positioned without excessive force, simplifying the structure and reducing the need for exclusive power supplies, and facilitating alignment even in fixed product robot attitudes.
Implementation Method 1
the robot side contact and the motor side contact are in a connection state in a state that the motor is held by the end effector... supply a power from a power source to the motor... actuate the electromagnetic brake
