[0038] The following will further illustrate the present utility model in conjunction with the attached Figures 1-12 drawings.

[0039] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in conjunction with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present utility model can be combined with each other without conflicting with each other.

[0040] Refer to Figures 1 to 12, the present utility model discloses a pole piece conveying line device, which includes an installation support 1, a driving mechanism 2, a negative pressure belt 4 and a vacuum adsorption mechanism 3. The installation support 1 is the base of the pole piece 6 conveying device for carrying and installing each component; the negative pressure belt 4 is sleeved on the driving mechanism 2 for conveying the pole piece 6; the driving mechanism 2 is used to drive the negative pressure belt 4 to rotate; the vacuum adsorption mechanism 3 is used to generate negative pressure on the negative pressure belt 4 to adsorb the pole piece 6.

[0041] Specifically, a plurality of adsorption holes (not marked in the figure) are formed on the negative pressure belt 4, and the adsorption holes on the negative pressure belt 4 are arranged in a way that they are dense in the middle and sparse on both sides. The adsorption holes in the middle of the negative pressure belt 4 are denser. When negative pressure is formed, the negative pressure in the middle part is stronger than that on both sides. When the pole piece 6 is placed on the negative pressure belt 4, due to the stronger negative pressure in the middle part of the negative pressure belt 4, the middle part of the pole piece 6 will be tightly adsorbed on the negative pressure belt 4, effectively reducing the possibility of the belt arching.

[0042] Refer to Figures 2 to 9 , the vacuum adsorption mechanism 3 is used to generate negative pressure on the negative pressure belt 4. The vacuum adsorption mechanism 3 is arranged on the installation support 1, and the negative pressure belt 4 is wound around the vacuum adsorption mechanism 3.

That is, the pole piece 6 is transmitted from the tail cavity assembly 31 through the aluminum profile cavity 32 to the head cavity assembly 33, and the pole piece 6 is taken at the head cavity assembly 33. The aluminum profile cavity 32 is fixedly installed on the installation support 1. The aluminum profile cavity 32 is provided with an upper slot 321, a middle slot 322 and a lower slot 323 from top to bottom, and the upper slot 321, the middle slot 322 and the lower slot 323 are all independent and not connected to each other. The upper slot 321 faces the negative pressure belt 4 side for forming a larger negative pressure area below the negative pressure belt 4, and the lower slot 323 is used for fixedly installing other components. Multiple groups of slots are evenly arranged on the aluminum profile cavity 32, and the length direction of each slot is consistent with the transmission direction of the negative pressure belt 4.

A larger negative pressure area can be formed on the negative pressure belt 4, and uniform negative pressure can be generated in each area of the negative pressure belt 4. Each part of the pole piece 6 receives the same negative pressure on the negative pressure belt 4, and it is not easy to arch during the transmission process.

[0043] A communication hole 324 is provided on the side of the aluminum profile cavity 32. The communication hole 324 penetrates through the side of the aluminum profile cavity 32, and the communication hole 324 communicates with the upper slot 321 and the middle slot 322.

The aluminum profile cavity 32 is connected with a profile pipe joint 325 at the communication hole 324, and the profile pipe joint 325 communicates with the communication hole 324. The profile pipe joint 325 is used to connect to an air source component, so that the air source component can form a negative pressure on the aluminum profile cavity 32.

[0044] The upper slot 321, the middle slot 322, and the lower slot 323 are all independently provided, which can effectively ensure the airtightness of the aluminum profile cavity 32. By connecting the upper slot 321 and the middle slot 322 through the communication hole 324 and then forming a negative pressure in it through the communication hole 324, the air flow can be effectively and evenly distributed, so that a uniform and stable negative pressure can be generated in each area of the aluminum profile cavity 32 facing the negative pressure belt 4, which is beneficial to the adsorption and stable transmission of the pole piece 6.

[0045] In some embodiments, the aluminum profile cavity 32 is formed by extrusion to form a separate groove-shaped space that is the same from front to back along the transmission direction of the pole piece 6, and the upper slot 321, the middle slot 322, and the lower slot 323 that are independent of each other from top to bottom.
