DETAILED DESCRIPTION

[0050] Some embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0051] The existing tab adsorption device usually realizes the taking and placing of the tab through an elastic suction cup. Since the tab is soft, the elastic suction cup needs to continue to press for a distance after contacting the tab when sucking the tab, because the adsorption force is concentrated around the suction cup, which may leave a circular indentation on the tab, causing the tab to deform, which may affect the normal use of the tab.

[0052] Based on this, the present application provides an adsorption plate, which can be fitted with the body and the tab lug of the tab by using the adsorption surface, the adsorption surface increases the contact area between the plate body and the tab, supports the tab while reducing the gap between the plate body and the tab, improves the stability of the plate body during the conveying process of the tab, opens an adsorption hole on the adsorption surface, which can form a negative pressure between the tab and the adsorption surface to realize the attraction of the tab, opens a cavity in the plate body, which uses the cavity as a buffer space between the air source and the adsorption hole, which can significantly improve the stability of the airflow in the adsorption hole, reduce the negative effects caused by the deformation of the pipeline connected to the air source during the movement process, and further improve the adsorption effect.

[0053] The present application will be described in detail below through specific embodiments.

[0054] Reference Figures 1 to 11 As shown in the drawings, the present embodiment provides an adsorption plate, which is used in a tab conveying mechanism, and the adsorption plate comprises: a plate body 1, the bottom surface of the plate body 1 is formed with an adsorption surface 11, the plate body 1 has a cavity 12 inside, the adsorption surface 11 is provided with an adsorption hole 13 which is in communication with the cavity 12, and the cavity 12 is used to connect an air source; the adsorption surface 11 has a main body adsorption surface 111 which is fitted with the main body of the tab and a tab lug adsorption surface 112 which is fitted with the tab lug of the tab, and the main body adsorption surface 111 and the tab lug adsorption surface 112 are both provided with the adsorption hole 13.

[0055] Based on the aforementioned adsorption plate, the adsorption surface 11 can be attached to the body and tabs of the electrode. The adsorption surface 11 increases the contact area between the plate body 1 and the electrode, supporting the electrode while reducing the gap between the plate body 1 and the electrode, thus improving the stability of the plate body 1 during the transport of the electrode. Adsorption holes 13 are opened on the adsorption surface 11, which can form a negative pressure between the electrode and the adsorption surface 11, thereby attracting the electrode. A cavity 12 is opened inside the plate body 1, which serves as a buffer space between the gas source and the adsorption holes 13. This can significantly improve the stability of the airflow in the adsorption holes 13, reduce the negative impacts of the gas source pipeline and suction cup on the electrode during the absorption and release of the electrode, such as electrode surface deformation, thereby further improving the adsorption effect.

[0056] Optionally, the adsorption hole 13 is provided with an open structure at the first end near the adsorption surface 11. Specifically, the open structure refers to an arc-shaped surface or inclined guide opening at the first end of the adsorption hole 13 where the cross-sectional area gradually decreases along the air flow direction. And / or, the adsorption hole 13 is provided with an open structure at the second end near the cavity 12. Specifically, the open structure refers to an arc-shaped surface or inclined guide opening at the second end of the adsorption hole 13 where the cross-sectional area gradually increases along the air flow direction.

[0057] Furthermore, based on the two open structures respectively opened at both ends of the adsorption hole 13, the adsorption hole 13 can form a Laval nozzle structure, which increases the air flow rate at the adsorption hole 13 without changing the gas source pressure, thereby further improving the adsorption capacity of the adsorption hole 13 for the electrode, and improving the adsorption stability and reliability of the adsorption hole 13.

[0058] Continue to refer to Figure 4 and Figure 5 As shown, the cavity 12 includes at least two interconnected flow channels.

[0059] Furthermore, based on the aforementioned cavity 12, the number of air source ports 14 can be reduced, further reducing the sealing difficulty of the cavity 12. At the same time, by utilizing the interconnection of multiple flow channels, the adsorption holes 13 located on the main body adsorption surface 111 and the adsorption holes 13 located on the tab adsorption surface 112 can be more easily connected to the same or more air source ports 14, reducing the number of air source ports 14 and also reducing the difficulty of setting up the air source ports 14.

[0061] Further, based on the above-mentioned flow channel, the flow channel is reasonably distributed according to the air flow and the opening position of the adsorption hole 13, and the main flow channel 121 and the branch flow channel 122 are staggered arranged in the cavity 12, which can significantly improve the arrangement range of the adsorption hole 13, and further improve the adsorption area of the plate body 1 to the pole piece.

[0062] In further embodiments, at least two main flow channels 121 have an intersection, and are in communication through the intersection, and the air source port 14 is arranged at the position of the intersection. This arrangement can minimize the air source port 14 while ensuring that the main flow channel 121 can have a lower air pressure to stably provide negative pressure to all adsorption holes 13. Alternatively, the main flow channel 121 can be arranged in a "king" shape on the plate body 1. In another embodiment, according to the actual installation of the adsorption plate, the air source port 14 can be arranged at the intersection of the main flow channel 121 and the branch flow channel 122 to improve the flow effect of the gas.

[0066] Further, based on the above-mentioned groove, the entire flow channel can be formed by the side wall of the flow guide block 17 and at least part of the inner wall of the base 15 or the cover plate 16, and a special-shaped groove can be further machined on the flow guide block 17 and at least part of the inner wall of the base 15 or the cover plate 16, thereby further improving the coverage area of the adsorption hole 13.

[0067] Optionally, the bottom of at least part of the flow guide block 17 is integrally formed with the base 15, and the top of the flow guide block 17 is sealingly matched with the cover plate 16. At this time, the top of the flow guide block 17 can be abutted against the cover plate 16 through a rubber pad or other elastic structure capable of forming a sealing effect through extrusion to achieve sealing matching, and / or the top of at least part of the flow guide block 17 is integrally formed with the cover plate 16, and the bottom of the flow guide block 17 is sealingly matched with the base 15. At this time, the bottom of the flow guide block 17 can be abutted against the base 15 through a rubber pad or other elastic structure capable of forming a sealing effect through extrusion to achieve sealing matching, so as to ensure that the airflow only flows on the side wall thereof.

[0068] Further, based on the arrangement mode of the flow guide block 17, the air can be limited in the main flow channel 121 or the branch flow channel 122, which can indirectly increase the negative pressure on each adsorption hole 13 and improve the stability of the negative pressure provided by each adsorption hole 13.

[0069] Optionally, at least one flow guide block 17 is provided with a mounting hole 18.

When the cover plate 16 is connected with the base 15, the sealing ring 19 needs to be extruded, and the sealing of the cavity 12 is realized through the deformation of the sealing ring 19. It should be noted that the connecting bolts for connecting the cover plate 16 and the base 15 can be arranged outside the sealing ring 19, so as to avoid the influence of the connecting bolts and bolt holes on the sealing effect of the cavity 12. In a further embodiment, the connecting bolts for connecting the cover plate 16 and the base 15 can be arranged in a range with small spacing from the sealing ring 19, so as to improve the sealing performance of the sealing ring 19 by using the pre-tightening force of the connecting bolts.
