Sealing ring grabbing device and system and sealing ring forming and assembling system

Abstract

The invention provides a sealing ring grabbing device and system and a sealing ring forming and assembling system, and relates to the technical field of sealing ring assembly. The sealing ring grabbing device comprises: a grabbing clamp lower working platform, wherein the working surface thereof is provided with a plurality of contact pin through holes and vacuum adsorption air holes; a grabbing clamp upper working platform provided with a plurality of grabbing contact pins suitable for penetrating through the contact pin through holes in the grabbing clamp lower working platform; a first driving mechanism used for driving the grabbing clamp upper working platform to move in the direction close to the grabbing clamp lower working platform, so that the grabbing contact pins penetrate out of the contact pin through holes to be inserted into the sealing rings, or the grabbing clamp upper working platform is driven to move in the direction away from the grabbing clamp lower working platform, so that the grabbing contact pins are retreated from the sealing rings and then drive the grabbing clamp lower working platform to move together; and a limiting mechanism. The technical problems that in the prior art, a sealing ring grabbing device is poor in reliability, and a sealing ring is prone to partially or integrally falling off in the grabbing or transferring process are solved.

Description

technical field [0001] The invention relates to the technical field of sealing ring assembly, in particular to a sealing ring grasping device, a sealing ring grasping system and a sealing ring forming and assembling system. Background technique [0002] Both the bipolar plate and the membrane electrode are the core components of the fuel cell stack. When the stack is assembled, they are stacked up and down. There are air, hydrogen and water sealing problems between them. Therefore, no matter how the sealing structure or method is designed, Sealing rings must be integrated on the bipolar plate or membrane electrode. Generally, in-situ injection molding or sealing ring bonding are used to integrate on the bipolar plate (or the protective frame of the membrane electrode). Since the metal plate needs to be stamped and formed, the two sides of the plate must be subjected to a force as the mainstream field. Influenced by the structure or shape of the side, and because the thickne...
