The present application is described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses a metallized film gripper for producing a film capacitor. Referring to fig. 1, a metallized film gripper for film capacitor production includes a mounting member 1 for mounting the gripper on a control device, a suction cup 2 mounted on the mounting member 1, and a plurality of bifurcated arms 3 connected to the suction cup 2.

Referring to fig. 2, the inside of the suction cup 2 is hollow, and a connection pipe 21 for connecting vacuum is connected to the top of the suction cup 2.

Referring to fig. 1, in this embodiment, the suction cup 2 has a circular cross section, and four bifurcation arms 3 are provided, and the four bifurcation arms 3 are uniformly spaced around the circumference of the suction cup 2. In other embodiments, the suction cup 2 may be rectangular or other regular polygons, and the number of the bifurcation arms 3 may be two, three or more according to the requirement, which is not particularly limited in this embodiment.

Referring to fig. 2 and 3, the bottom of the suction cup 2 is opened, a first elastic support 4 is installed in the opening at the bottom of the suction cup 2, and the circumferential contour of the first elastic support 4 is consistent with the contour of the opening at the bottom of the suction cup 2.

The second elastic support piece 5 is arranged in the mounting opening, the second elastic support piece 5 is fixedly adhered to the inner wall of the mounting opening, and a plurality of vacuum suction holes 51 are uniformly and densely distributed on the second elastic support piece 5. When the vacuum is not communicated for suction, the horizontal height of the bottom surface of the sucker 2, the horizontal height of the lower surface of the first elastic support piece 4 and the horizontal height of the lower surface of the second elastic support piece 5 are consistent.

The first elastic supporting member 4 may be made of rubber or silica gel, which is not particularly limited in comparison with the present embodiment. The second elastic supporting member 5 is a mesh fabric woven by using nylon material warp and weft knitting, the vacuum suction holes 51 are mesh holes on the mesh fabric, and in other embodiments, the second elastic supporting member 5 may also be a mesh fabric woven by using polyester or cotton thread material warp and weft knitting.

Referring to fig. 1, an auxiliary suction assembly is mounted on the bifurcated arm 3, and is composed of an air pipe 61 penetrating through the bifurcated arm 3 in a vertical direction and a suction nozzle 62 connected to the bottom end of the air pipe 61, wherein the horizontal height of the bottom surface of the suction nozzle 62 is identical to the horizontal height of the bottom surface of the suction cup 2 when vacuum is not communicated for suction. 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.

Under the action of vacuum suction, the first elastic support 4 is easier to deform with the annular groove 41 as the deformation point, so that the contact with the metallized film is better buffered.

Referring to fig. 1 and 3, the inside of the bifurcated arm 3 is hollow, the top surface and the bottom surface of the bifurcated arm 3 are provided with a sliding groove 31 along the length direction of the bifurcated arm 3, an air pipe 61 is arranged in the sliding groove 31 in a penetrating manner, a sliding block 63 is fixedly sleeved on the air pipe 61, and the sliding block 63 is in sliding fit with the sliding groove 31 on the top surface and the bottom surface of the bifurcated arm 3. When the device is applied, the position of the suction nozzle 62 can be adjusted by sliding the sliding block 63, so that metallized films with different sizes can be adapted.

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.
