The suction nozzle 62 is made of rubber, silicone or other flexible material, which is not particularly limited in this embodiment.
When the vacuum suction device is applied, the suction cup 2 and the auxiliary suction component are connected to vacuum, the suction cup 2 sucks the middle part of the metallized film, the suction nozzle 62 sucks the edge part of the metallized film, and the suction cup 2 and the auxiliary suction component are matched to realize multi-part suction of the metallized film. When the suction is carried out, under the action of vacuum suction, when the metallized film is contacted with the first elastic supporting piece 4 and the second elastic supporting piece 5, the first elastic supporting piece 4 and the second elastic supporting piece 5 can be sunken towards the inner side of the sucker 2 to slightly deform, so that the contact with the metallized film is buffered, the protection of the metallized film is realized, and the possibility of excessive deformation of the metallized film is reduced.

Further, the scale marks 32 are arranged on the bifurcation arms 3, and the distance between the sliding blocks 63 on the bifurcation arms 3 and the sucker 2 is kept consistent through the scale marks 32 during suction, so that vacuum suction points are uniformly distributed on the metallized film, the stress of the metallized film is more uniform when the metallized film is sucked, and the suction is more stable.
The implementation principle of the metallized film gripper for producing the film capacitor is as follows: the middle part of the metallized film is sucked through the sucker 2, so that the main sucking effect is achieved, the edge part of the metallized film is sucked through the auxiliary sucking component, the auxiliary sucking effect is achieved, the two parts are matched to achieve multi-part sucking of the metallized film, the metallized film is kept as smooth as possible, and excessive bending of the metallized film caused by falling of other parts under the action of gravity due to the fact that only the middle part or the edge part of the metallized film is sucked is avoided. When the vacuum suction force is absorbed, the first elastic support piece 4 and the second elastic support piece 5 can slightly deform when being contacted with the metallized film, so that the contact with the metallized film is buffered, and the possibility that the metallized film excessively deforms at the position opposite to the vacuum suction hole 51 at the moment of being absorbed is reduced. Because the suction force of the area of the sucker 2 is concentrated on the first elastic support 4, the part of the metallized film surrounding the first elastic support 4 can be slightly deformed integrally along with the deformation of the second elastic support 5, and the integral deformation can disperse and buffer the force applied to the metallized film when the metallized film is sucked by the first elastic support 4, so that the excessive deformation of the metallized film is avoided, the integral deformation amplitude of the metallized film is small, the metallized film belongs to reversible deformation, and the metallized film can be automatically recovered after the suction force is relieved, so that the metallized film can still maintain good flatness after the suction movement.
The foregoing is a preferred embodiment of the present application, and is not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
