Description

Technical Field

[0001] This utility model relates to the field of adsorption plate technology, and in particular to a vacuum adsorption plate structure. Background Technology

[0002] During the gripping and conveying of battery cell electrodes, the flatness and positional accuracy of the electrodes have a significant impact on their alignment. Generally, suction cup negative pressure handling or planar suction cup adsorption handling is used to transport the electrodes. In existing technologies, when planar suction cups adsorb electrodes, the negative pressure formed at each adsorption port of the planar suction cup is different, causing the electrodes to bulge after being adsorbed, or one side to be adsorbed while the other side has not yet been adsorbed. Furthermore, the response time of the suction cup negative pressure is relatively long, resulting in a longer cycle time for the suction cup to adsorb the electrodes, which affects the production efficiency of the battery cell. Summary of the Invention

[0003] According to an embodiment of the present invention, a vacuum adsorption plate structure is provided, comprising: an adsorption shell, a negative pressure suction port, and a contact layer;

[0004] The adsorption housing includes: an outer shell, an adsorption top plate, and an adsorption bottom plate;

[0005] The top and bottom plates of the adsorption system are respectively located at the top and bottom ends of the outer shell. A negative pressure chamber is formed inside the outer shell. The negative pressure suction port is located on the top plate and is connected to the negative pressure chamber. The bottom plate of the adsorption system has negative pressure adsorption holes that are connected to the negative pressure chamber for adsorbing materials. The contact layer is located below the bottom plate of the adsorption system and has a porous elastic structure.

[0006] Furthermore, multiple negative pressure adsorption holes are equidistantly opened on the adsorption base plate.

[0007] Furthermore, the thickness of the negative pressure chamber is 1mm to 3mm.

[0008] Furthermore, the thickness of the contact layer is 1mm to 2mm.

[0009] Furthermore, the contact layer is a sponge with a hardness of H50.

[0010] Furthermore, the negative pressure suction port is connected to a negative pressure adsorption valve body.

[0011] According to a vacuum adsorption plate structure of this utility model embodiment, when adsorbing the electrode sheet, the electrode sheet wire contacts the contact layer, and the electrode sheet will squeeze the contact layer to expel the air between the electrode sheet and the adsorption base plate, ensuring the flatness of the electrode sheet. The negative pressure suction port makes the negative pressure chamber quickly form a uniform vacuum environment, and the vacuum condition is quickly transmitted to the negative pressure adsorption hole, which stably adsorbs the electrode sheet, realizing the rapid adsorption of the electrode sheet and avoiding the bulging or unevenness of the electrode sheet after adsorption, thereby improving the production efficiency of the battery cell.

[0012] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0013] Figure 1 This is a structural diagram of a vacuum adsorption plate structure according to an embodiment of the present invention;

[0014] Figure 2 This is a front view of a vacuum adsorption plate structure according to an embodiment of the present invention;

[0015] Figure 3 This is a bottom view of a vacuum adsorption plate structure according to an embodiment of the present invention.

[0016] In the figure, the following labels are used: 1 is the outer shell, 2 is the top adsorption plate, 3 is the bottom adsorption plate, 4 is the negative pressure suction port, 5 is the contact layer, and 6 is the negative pressure adsorption hole. Detailed Implementation

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0018] First, combine Figures 1-3 This invention describes a vacuum adsorption plate structure according to an embodiment of the present invention, used for adsorbing electrode sheets.

[0019] like Figures 1-3 As shown, a vacuum adsorption plate structure according to an embodiment of the present invention includes: an adsorption shell, a negative pressure suction port 4, and a contact layer 5;

[0020] The adsorption shell includes: an outer shell 1, an adsorption top plate 2, and an adsorption bottom plate 3;

[0021] The top adsorption plate 2 and the bottom adsorption plate 3 are respectively located at the upper and lower ends of the outer shell 1, forming a negative pressure chamber inside the outer shell 1. The negative pressure suction port 4 is located on the top adsorption plate 2 and communicates with the negative pressure chamber. The bottom adsorption plate 3 has a negative pressure adsorption hole 6, which communicates with the negative pressure chamber and is used to adsorb materials. The contact layer 5 is located below the bottom adsorption plate 3 and has a porous elastic structure. The negative pressure suction port 4 is connected to a negative pressure adsorption valve body.

[0022] In this application, when the electrode is adsorbed, the electrode wire contacts the contact layer 5, and the electrode will squeeze the contact layer 5 to expel the air between the electrode and the adsorption base plate 3, ensuring the flatness of the electrode. The negative pressure suction port 4 quickly forms a uniform vacuum environment in the negative pressure chamber, and the vacuum condition is quickly transmitted to the negative pressure adsorption hole 6, which stably adsorbs the electrode, realizing rapid adsorption of the electrode and avoiding bulging or unevenness of the electrode after adsorption, thereby improving the production efficiency of the battery cell.

[0023] like Figures 2-3 As shown, multiple negative pressure adsorption holes 6 are equidistantly arranged on the adsorption base plate 3. The thickness of the negative pressure chamber is 1mm to 3mm.

[0024] Multiple negative pressure adsorption holes 6 can ensure uniform adsorption of the electrode sheet, limit the thickness of the negative pressure chamber so that the negative pressure generated by each negative pressure adsorption hole 6 is the same, and avoid bulging and unevenness.

[0025] like Figures 2-3 As shown, the thickness of the contact layer 5 is 1mm to 2mm. The contact layer 5 is a sponge with a hardness of H50.

[0026] In this embodiment, the electrode is first in contact with the contact layer 5 before being adsorbed, and the electrode is compressed with a sponge with a hardness of H50 to ensure the flatness of the electrode.

[0027] Above, refer to Figures 1-3 This invention describes a vacuum adsorption plate structure according to an embodiment of the present invention. When adsorbing the electrode sheet, the electrode sheet wire contacts the contact layer 5, and the electrode sheet squeezes the contact layer 5 to expel the air between the electrode sheet and the adsorption base plate 3, ensuring the flatness of the electrode sheet. The negative pressure suction port 4 quickly forms a uniform vacuum environment in the negative pressure chamber, and the vacuum condition is quickly transmitted to the negative pressure adsorption hole 6, which stably adsorbs the electrode sheet, achieving rapid adsorption of the electrode sheet and avoiding bulging or unevenness of the electrode sheet after adsorption, thereby improving the production efficiency of the battery cell.
