[0045] The embodiment provides a gluing device, which can be used for edge gluing of a positive plate to avoid that burrs of the edge of the positive plate pierce a solid-state electrolyte layer and cause short circuit of a battery.

[0046] Specifically, as Figures 1-3As shown, the glue coating device comprises a glue coating table 100, a cover plate assembly 200, and a glue coating driving mechanism 300. The glue coating table 100 comprises a bearing surface 121 for bearing the pole piece and a glue coating groove 122 arranged along the circumference of the bearing surface 121, and the edge of the pole piece is located in the glue coating groove 122. The cover plate assembly 200 is located above the glue coating table 100, and the side of the cover plate assembly 200 facing the glue coating table 100 is provided with an abutting surface 221 and a glue injection groove 222 arranged along the circumference of the abutting surface 221, and the glue injection groove 222 is provided with a glue injection hole 2221, and the abutting surface 221 is used for abutting the pole piece. The glue coating driving mechanism 300 is connected with the cover plate assembly 200, and is used for driving the cover plate assembly 200 to move to the directly above of the glue coating table 100, and driving the cover plate assembly 200 to abut the pole piece on the bearing surface 121 downward, so that the glue injection groove 222 and the glue coating groove 122 correspond and enclose a cavity.

[0047] When the glue coating device works, the pole piece to be coated is placed on the bearing surface 121 of the glue coating table 100, and the circumferential edge of the pole piece covers the glue coating groove 122. The cover plate assembly 200 is moved to the directly above of the glue coating table 100 by the glue coating driving mechanism 300, so that the abutting surface 221 on the cover plate assembly 200 is aligned with the bearing surface 121, and the glue injection groove 222 is opposite to the glue coating groove 122. The glue coating driving mechanism 300 drives the cover plate assembly 200 downward, the abutting surface 221 contacts the pole piece, the glue injection groove 222 and the glue coating groove 122 enclose a cavity, and glue is injected into the cavity through the glue injection hole 2221, so as to wrap the edge of the pole piece with glue, preventing the burr of the edge of the pole piece from piercing the solid electrolyte layer and causing short circuit of the battery.

[0048] In the glue coating device provided by the embodiment, the abutting surface 221 and the bearing surface 121 can shield the position of the pole piece that does not need to be coated with glue, so as to avoid the diffusion of glue to the center of the pole piece during the coating process, thereby effectively controlling the coating position on the pole piece and ensuring the coating precision. By injecting glue into the cavity, the glue can automatically wrap the edge of the pole piece, the coating efficiency is high, and the coating quality and consistency can be ensured, the large-scale production is realized, and the problems of high labor cost, low efficiency, unguaranteed quality and consistency, and easy occurrence of air bubbles and other defects in the manual glue sticking in the prior art are solved.

[0049] In combination Figure 1 and Figure 2 As shown, in some embodiments, the glue coating groove 122 is an annular groove, which surrounds the outside of the bearing surface 121, so that the four edges of the pole piece can cover the glue coating groove 122, so as to be in contact with the glue during the coating process. Correspondingly, as shown in Figure 3 the glue injection groove 222 is an annular groove, which surrounds the outside of the abutting surface 221, so as to cooperate with the glue coating groove 122 to enclose an annular cavity.

[0050] In other embodiments, the glue applying groove 122 and the glue injecting groove 222 can be strip-shaped, L-shaped or U-shaped, and the shape of the glue applying groove 122 and the glue injecting groove 222 can be set according to actual needs, corresponding to the fact that the enclosed cavity only includes one side, two sides or three sides of the edge of the pole piece.

[0051] In some embodiments, the bearing surface 121 can be flush with the top end of the glue applying groove 122, that is, the bearing surface 121 is flush with the side surface of the glue applying table 100 where the bearing surface 121 is located; correspondingly, the abutting surface 221 is flush with the top surface of the glue injecting groove 222, that is, the abutting surface 221 is flush with the surface of the cover plate assembly 200 where the abutting surface 221 is located. When the cover plate assembly 200 presses down the pole piece, since the pole piece is thin, the cover plate assembly 200 can be in contact with the glue applying table 100, or the gap between the cover plate assembly 200 and the glue applying table 100 is small, preventing the glue from overflowing.

[0052] In other embodiments, the glue applying table 100 is provided with a first groove, part of the bottom surface of the first groove forms the bearing surface 121, and the glue applying groove 122 is located on the bottom surface of the first groove; the cover plate assembly 200 is provided with a second groove, part of the bottom surface of the second groove forms the abutting surface 221, and the glue injecting groove 222 is located on the bottom surface of the second groove, wherein the depth of the first groove and the second groove is less than or equal to the thickness of the pole piece. When the cover plate assembly 200 presses down, the space for accommodating the pole piece is formed between the bottom surfaces of the first groove and the second groove, ensuring that the pole piece can be in contact with the bearing surface 121 and the abutting surface 221 respectively, and the outside gap of the cavity is closed through the contact between the cover plate assembly 200 and the glue applying table 100, avoiding the glue from overflowing.

[0053] In some embodiments, at least one of the abutting surface 221 and the bearing surface 121 is covered with an elastic layer, which can be in elastic contact with the pole piece, avoiding the rigid contact between the cover plate assembly 200 or the glue applying table 100 and the pole piece, which can damage the pole piece.

[0054] Optionally, the elastic layer can be made of elastic materials, such as rubber, silicone or sponge.

[0055] In order to ensure that the glue layer after gluing can fully wrap the edge of the pole piece, in some embodiments, the outer contour size of the cavity is greater than the size of the pole piece, so that the edge of the pole piece can be arranged in a spaced manner with the outside circumferential side wall of the cavity, so as to ensure that the pole piece cannot separate the glue injecting groove 222 and the glue applying groove 122, so that the glue can flow from the glue injecting groove 222 to the glue applying groove 122, and wrap the opposite two side surfaces and side surface of the edge of the pole piece.

[0056] Exemplarily, taking the pole piece as a rectangle, and the glue injecting groove 222 and the glue applying groove 122 as rectangular grooves as an example, the size of the outer contour of the rectangular groove along the X direction is greater than the size of the pole piece along the X direction, and the size of the outer contour of the rectangular groove along the Y direction is greater than the size of the pole piece along the Y direction, so that the pole piece can be completely accommodated in the cavity.

[0057] Optionally, the slot width of the rectangular slot along the X direction can be the same as the slot width of the rectangular slot along the Y direction, or can be different, and the specific size can be set according to the required glue coating width of each edge of the pole piece.

[0058] In order to ensure the accuracy of the glue coating position, in some embodiments, the bearing surface 121 is provided with a plurality of adsorption holes 1211, and the adsorption holes 1211 are used to communicate with a vacuum device to adsorb the pole piece. By providing the adsorption holes 1211, the pole piece can be fixed to ensure that the position of the pole piece does not move, thereby ensuring the accuracy of the glue coating position.

[0059] Optionally, a plurality of adsorption holes 1211 are uniformly and spacedly arranged on the bearing surface 121, and the plurality of adsorption holes 1211 are arranged to increase the adsorption area and adsorption force of the pole piece and improve the fixing effect of the pole piece.

[0060] For example, the plurality of adsorption holes 1211 can be arranged in a matrix to uniformly distribute the adsorption force received by the pole piece.

[0065] As shown in Figure 3 and Figure 5 some embodiments, a plurality of glue injection holes 2221 are arranged in the glue injection groove 222 to quickly inject glue into the cavity and improve the glue coating efficiency.

[0066] To facilitate the injection of adhesive into the cavity through multiple injection holes 2221, in some embodiments, such as Figure 5 and Figure 6 As shown, a buffer cavity 211 is provided inside the cover plate assembly 200, and an adhesive inlet 212 is provided on the cover plate assembly 200.

[0067] In some embodiments, the cover plate assembly 200 is also provided with an air port 213 communicating with the buffer cavity 211. The air port 213 is used to introduce compressed gas to accelerate the flow of adhesive in the buffer cavity 211, so that the adhesive can enter the cavity more quickly and smoothly through the adhesive injection hole 2221, thereby covering the edge of the electrode sheet.
