[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The purpose of the utility model is to provide a positioning device for a sleeve transfer process, so as to solve the problems existing in the above-mentioned related technologies and realize that the same sleeve can be transferred to the end in the entire production process of rolled copper foil.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0045] Reference Figures 1 to 19 This embodiment provides a positioning device for a sleeve transfer process, including a transfer cone head 1, a positioning block 2 and a positioning bracket.

[0046] The transfer cone head 1 has an outer conical surface, which is used to abut against the inner conical surface of the sleeve end, so that the transfer cone head 1 and the sleeve are coaxial. There are two transfer cone heads 1, which are respectively located at the two ends of the sleeve.

[0047] A first groove is provided on the end face of the transfer cone head 1 facing away from the sleeve, and a first screw hole is provided at the bottom of the first groove. The first groove is used to accommodate the installation cone head of the unwinder (i.e., uncoiler or winder), and the first screw hole is used to install the cone head by screw connection.

[0048] A second groove is provided on the side of the transfer cone head 1, and a second screw hole is provided at the bottom of the second groove. The second screw hole is used to connect the positioning block 2 through a screw. The positioning block 2 is used to be embedded in the positioning groove at the end of the sleeve to position the transfer cone head 1 and the sleeve relative to each other along the circumferential direction.

[0049] The positioning bracket is used to support the sleeve.

[0050] The working principle of the positioning device during the sleeve transfer process of this embodiment is as follows:

[0051] In this embodiment, the transfer cone head 1 is used as an intermediate piece between the installation cone head and the sleeve. The transfer cone head 1 supports the end of the sleeve during the entire process of sleeve transfer, so that the end of the sleeve remains completely round, which is conducive to maintaining the shape of the rolled copper foil carried by the sleeve. At the same time, since the installation cone head does not need to support the transfer cone head 1 from the inside, the outer contour of the installation cone head can be the same as the size of the first groove, or it can be smaller than the size of the first groove. Therefore, the first groove can connect installation cone heads of various sizes, so that the sleeve can be installed on various unwinding machines without changing the sleeve, so that the same sleeve can be circulated throughout the entire rolled copper foil production process.

[0052] As a possible example, in this embodiment, the sidewall of the first groove is provided with a positioning groove, which is used to engage with a protrusion on the side of the mounting cone head to limit the transfer cone head 1 and the mounting cone head relative to each other along the circumferential direction. The cooperation between the positioning groove and the protrusion can bear a certain circumferential force, thereby reducing the shear force on the screw connecting the transfer cone head 1 and the mounting cone head, and extending the service life of the screw.

[0053] As a possible example, in this embodiment, the positioning bracket includes a bracket 3, a baffle 4 and a stopper 5. The upper surface of the bracket 3 includes an arc surface and mounting surfaces located on both sides of the arc surface. The radius of curvature of the arc surface is not less than the radius of the sleeve so that the end of the sleeve is supported by the arc surface. The radius of curvature of the arc surface is preferably the same as the radius of the sleeve. Stoppers 5 are installed on both mounting surfaces to limit the rolling of the sleeve from both sides. The baffle 4 is installed on the end face of the bracket 3 away from the sleeve so that the baffle 4 and the sleeve are axially limited to each other. There are two positioning brackets, and the two positioning brackets are respectively located at both ends of the sleeve.

[0054] By providing the arc surface on the bracket 3, the contact area between the bracket 3 and the sleeve can be increased, thereby reducing the pressure on the sleeve and preventing the sleeve from being crushed. At the same time, the arc surface can play an anti-rolling role, thereby confining the sleeve to the area where the arc surface is located.

[0055] The height of the stopper 5 is higher than the height of the upper edge of the arc surface. If the sleeve wants to climb over the stopper 5, it needs to have greater kinetic energy, so the stopper 5 further limits the position of the sleeve and prevents the sleeve from leaving the arc surface.

[0056] When the sleeve slides on the bracket 3 along its own axial direction, or has a tendency to slide along the axial direction, the baffle 4 can limit the axial position of the sleeve by abutting against the end surface of the sleeve.

[0057] Therefore, the positioning bracket of this embodiment can limit the rolling and axial sliding of the sleeve during transportation, so that the position of the sleeve remains stable.

[0058] In this embodiment, the bracket 3 and baffle 4, as well as the bracket 3 and stopper 5, are connected by screws to facilitate component replacement. This allows brackets 3 with different curvature radii to accommodate sleeves of varying sizes. It is understood that if the sleeve size remains unchanged, those skilled in the art may also integrally connect the bracket 3, baffle 4, and stopper 5 using a non-detachable connection method such as welding.

[0059] As a possible example, in this embodiment, the material of bracket 3 is 40Cr, the material of baffle 4 is Q235B, and the material of stopper 5 is Q235B. The material of transfer cone head 1 is 42CrMo, and the hardness of transfer cone head 1 is 58-60HRC. The material of positioning block 2 is 42CrMo, and the hardness of positioning block 2 is 30-32HRC. Those skilled in the art can flexibly select the material and hardness of each component according to actual needs.

[0060] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
