Background

The copper foil is needed in the production process of the lithium battery, the copper plating treatment needs to be carried out on the two sides of the thin film in the production process of the copper foil, the implementation principle of the copper foil is shown in figure 1, titanium blue 1 is arranged on the two sides of the thin film 2 in parallel, a plurality of copper balls are placed inside the titanium blue 1, the thin film 2 is provided with a current cathode by providing a current anode on the titanium blue 1, and copper ions are plated on the surface of the thin film 2 in a bath 3 through electrochemical reaction. As shown in fig. 2, in the above-mentioned copper plating process, the film 2 is located between two titanium blues 1 and moves through the transmission shaft 4, copper ions electrolyzed from the copper balls at the middle of the titanium blues 1 will move towards the film 2 along with the electric field direction 5, and copper ions electrolyzed from the copper balls at the bottom of the titanium blues 1 will diffuse and plate onto the film 2 along with the interference electric field direction 6, thereby generating defects such as uneven plating film and spots.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at: the shielding structure of the titanium blue is provided aiming at the problems of uneven coating and spot defects generated during thin film copper plating, copper ions diffusing to the edge are blocked by arranging the shielding plate at the bottom of the titanium blue, and poor products caused by copper ion diffusion are avoided.

In order to realize the purpose, the utility model discloses a technical scheme be:

the shielding structure of the titanium blue comprises a shielding plate connected with the bottom of the titanium blue, wherein the shielding plate is made of insulating materials, the shielding plate extends towards the direction of a film, and a gap is reserved between the side face of the shielding plate and the surface of the film.

The utility model discloses a set up insulating shield plate in the blue bottom of titanium, and the shield plate extends towards the film direction, can block the copper ion to the edge diffusion to avoid because of the product that the copper ion diffusion leads to is bad, and leaves the clearance volume between shield plate side and the film surface, make shield plate side can not take place the contact with the film, take place the friction with shield plate side when avoiding copper-plating in-process film to remove.

As the preferred scheme of the utility model, the shield plate is detachable with the titanium blue and is connected. In this way, the shield plate can be removed when dealing with an abnormal situation or performing maintenance.

As the preferred scheme of the utility model, the shield plate is connected through a plurality of moment of torsion hinge with the blue bottom of titanium. After the shielding plate is connected with the titanium blue through the torque hinge, the shielding plate can rotate relative to the titanium blue, the torque hinge can enable the shielding plate to be kept at the position after rotation, the shielding plate can be directly rotated and folded when abnormal conditions are processed or maintenance is carried out, the shielding plate does not need to be detached, and the operation is more convenient.

As the preferred scheme of the utility model, the clearance amount is 3-5 mm.

As the preferred scheme of the utility model, the shielding plate is made for the PVC material.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses a set up insulating shield plate in the blue bottom of titanium, and the shield plate extends towards the film direction, can block the copper ion to the edge diffusion to avoid the product bad because of the copper ion diffusion leads to, and leave the clearance volume between shield plate side and the film surface, make shield plate side can not contact with the film, avoid taking place the friction with shield plate side when the film moves in the copper facing process;

2. after the shielding plate is connected with the titanium blue through the torque hinge, the shielding plate can rotate relative to the titanium blue, the torque hinge can enable the shielding plate to be kept at the position after rotation, the shielding plate can be directly rotated and folded when abnormal conditions are processed or maintenance is carried out, the shielding plate does not need to be detached, and the operation is more convenient.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Examples

The embodiment provides a shielding structure of titanium blue;

as shown in fig. 3 and 4, the shielding structure of titanium blue in this embodiment includes a shielding plate 7 connected to the bottom of the titanium blue 1, a plate surface of the shielding plate 7 is perpendicular to the thin film 2, the shielding plate 7 is made of an insulating material, the shielding plate 7 extends toward the thin film 2, and a gap is left between a side surface of the shielding plate 7 and a surface of the thin film 2.
