Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic electromagnet assembly technology, specifically a gripping mechanism for an automatic electromagnet assembly line. Background Technology
[0002] Electromagnets, as core driving components in automated equipment, are widely used in industrial machinery, automobile manufacturing, electronic equipment, and other fields. In the automated production process of electromagnets, the gripping mechanism is a key piece of equipment for achieving precise handling and assembly of parts, and its performance directly affects assembly efficiency and product quality.
[0003] Currently, pneumatic clamps are commonly used as gripping mechanisms in automated electromagnet assembly lines, relying on compressed air to drive the gripper's movement.
[0004] However, these traditional solutions have obvious drawbacks:
[0005] (1) The pneumatic system relies on an external air source. Once the air supply is interrupted or the air pressure is unstable, the clamping force will drop sharply or even fail completely, causing production to be interrupted or the workpiece to fall off.
[0006] (2) The lack of real-time clamping force monitoring function makes it difficult to accurately control the clamping force, which can easily lead to damage to precision workpieces due to overpressure or displacement due to insufficient clamping.
[0007] Therefore, we propose a gripping mechanism for an automated electromagnet assembly line. Utility Model Content
