Description

Battery cell suction cup Technical Field

[0001] This invention relates to the field of suction cups, and in particular to suction cups for battery cells. Background Technology

[0002] During the transfer of solar cells, specialized suction cups are often required. These suction cups are typically made of ceramic. The suction cup includes a substrate and a sealing plate connected to the substrate. An air channel is provided in the space between the substrate and the sealing plate. The side of the substrate opposite the sealing plate is the adsorption surface, which has multiple adsorption holes. The air channel communicates with these adsorption holes and an end air hole. The end air hole is a hole located at the end of the suction cup and is used to connect to a vacuum mechanism. The suction cup adsorbs the solar cells through the multiple adsorption holes. These adsorption holes are generally circular.

[0003] Traditional suction cups are prone to clogging due to their small-diameter circular suction holes. Furthermore, the numerous holes make it difficult to quickly identify which hole is blocked. Even if identified, the large number of blocked holes makes rapid unblocking challenging. Multiple blocked holes reduce the suction cup's adsorption capacity, making it easier for the battery cells to detach from the cup.

[0004] For example, Chinese Patent 202111084779.6 discloses a silicon wafer picking device, and the suction cup used in this device has the aforementioned problem.

[0005] To address these issues, one approach is to create straight, strip-shaped grooves on the surface of the suction cup, which serve as flow channels. Adsorption holes are then formed within these grooves. This reduces the number of adsorption holes required, accommodating only a few. However, during use, the relatively long grooves and thin battery cells cause micro-cracks to form on some cells due to localized deformation caused by the suction force of the grooves. Summary of the Invention

[0006] Therefore, it is necessary to provide a battery cell suction cup that addresses the problem that traditional suction cups can easily cause micro-cracks in battery cells.

[0007] A battery cell suction cup includes a substrate and a sealing plate connected to the substrate. An air channel is provided in the space between the substrate and the sealing plate. The side of the substrate opposite to the sealing plate is an adsorption surface. The adsorption surface is provided with a plurality of adsorption holes. The air channel is connected to the plurality of adsorption holes and an end air hole. A concave guide groove is also provided on the adsorption surface. The opening of the adsorption hole is located in the guide groove. The guide groove includes intersecting transverse guide branches and longitudinal guide branches. The transverse guide branches include a plurality of first-type straight segments, and a first-type arc segment is formed between two adjacent first-type straight segments. The longitudinal guide branches include a plurality of second-type straight segments, and a second-type arc segment is formed between two adjacent second-type straight segments.

[0008] This application divides a long straight guide channel into multiple shorter guide channels, and sets an arc-shaped guide channel between two adjacent straight guide channels, which can effectively avoid the generation of micro-cracks on the battery cell.

[0009] In one embodiment, the substrate includes a main body and two outwardly extending branches, with a splicing groove formed between the two branches. The lateral flow guide branch extends from the main body to the branch, and the longitudinal flow guide branch is located on the main body.

[0010] In one embodiment, the two branches are a first branch and a second branch, with the first branch located above the second branch, and the width of the first branch being less than or greater than the width of the second branch.

[0011] In one embodiment, the width of the first branch is smaller than the width of the second branch, and the number of lateral guide branches on the first branch is smaller than the number of lateral guide branches on the second branch.

[0012] In one embodiment, the width of the second branch is less than the width of the first branch, and the number of lateral guide branches on the second branch is less than the number of lateral guide branches on the first branch.

[0013] In one embodiment, the upper end of the longitudinal guide branch intersects with the transverse guide branch on the first branch, and the lower end of the longitudinal guide branch intersects with the transverse guide branch on the second branch.

[0014] In one embodiment, the adsorption hole is provided at the end of the transverse guide branch on the first branch, the adsorption hole is provided at the end of the transverse guide branch on the second branch, and the adsorption hole is provided on the second type of arc segment of the longitudinal guide branch.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] As shown in Figures 1 and 3, an embodiment of this application provides a battery cell suction cup. The suction cup includes a substrate and a sealing plate connected to the substrate. An air channel is provided in the space between the substrate and the sealing plate. The side of the substrate opposite to the sealing plate is an adsorption surface 151. The adsorption surface 151 is provided with a plurality of adsorption holes 131. The air channel is connected to the plurality of adsorption holes 131 and an end air hole 141. The end air hole 141 is used to connect to a vacuuming mechanism. The adsorption surface 151 is also provided with a concave guide groove. The opening of the adsorption hole 131 is located in the guide groove. The guide groove includes intersecting transverse guide branches 121 and longitudinal guide branches 122. The transverse guide branches 121 include multiple first-type straight segments 1211, and a first-type arc segment 1212 is formed between two adjacent first-type straight segments 1211. The longitudinal guide branches 122 include multiple second-type straight segments 1221, and a second-type arc segment 1222 is formed between two adjacent second-type straight segments.

[0024] As shown in Figure 1, this application divides a long straight guide channel into multiple shorter guide channels, and sets an arc-shaped guide channel between two adjacent straight guide channels. This effectively avoids the formation of microcracks on the battery cell. For example, the transverse guide branch 121 includes two first-type straight segments 1211, and one first-type arc segment 1212 is located between the two first-type straight segments 1211. The longitudinal guide branch 122 also includes two second-type straight segments 1221, and one second-type arc segment 1222 is located between the two second-type straight segments 1221.

[0025] In one embodiment, as shown in FIG1, the substrate includes a main body 111 and two outwardly extending branches, with a splicing groove 114 formed between the two branches. A lateral flow guide 121 extends from the main body 111 to the branches; that is, a portion of the lateral flow guide 121 is located on the main body 111, and another portion is located on the branches. A longitudinal flow guide 122 is located on the main body 111. For example, the splicing groove 114 of the suction cup shown in FIG1 is used to accommodate the first branch 112 of the suction cup shown in FIG3. The splicing groove of the suction cup shown in FIG3 is used to accommodate the second branch 113 of the suction cup shown in FIG1.

[0026] In one embodiment, as shown in Figures 1 and 3, the two branches are a first branch 112 and a second branch 113. The first branch 112 is located above the second branch 113. In Figure 1, the width of the first branch 112 is smaller than the width of the second branch 113, while in Figure 2, the width of the first branch 112 is greater than the width of the second branch 113. The suction cups shown in Figure 1 and Figure 2 can be used together.

[0027] In one embodiment, as shown in Figures 1 and 2, the width of the first branch 112 is smaller than the width of the second branch 113, and the number of lateral guide branches 121 on the first branch 112 is less than the number of lateral guide branches 121 on the second branch 113. For example, the first branch 112 has one lateral guide branch 121, and the second branch 113 has two lateral guide branches 121.

[0028] In one embodiment, as shown in Figures 3 and 4, the width of the second branch 113 is smaller than the width of the first branch 112, and the number of lateral guide branches 121 on the second branch 113 is less than the number of lateral guide branches 121 on the first branch 112. For example, the first branch 112 has two lateral guide branches 121, while the second branch 113 has one lateral guide branch 121.

[0029] In one embodiment, the upper end of the longitudinal guide branch 122 intersects with the transverse guide branch 121 on the first branch 112, and the lower end of the longitudinal guide branch 122 intersects with the transverse guide branch 121 on the second branch 113.

[0030] In one embodiment, the adsorption hole 131 is provided at the end of the transverse flow guide branch 121 on the first branch 112, the adsorption hole 131 is provided at the end of the transverse flow guide branch 121 on the second branch 113, and the adsorption hole 131 is provided on the second type of arc segment 1222 of the longitudinal flow guide branch 122.

[0031] For example, as shown in Figure 1, there are three adsorption holes 131. The transverse flow guide branch 121 on the first branch 112 is the first transverse flow guide branch 121. The two transverse flow guide branches 121 on the second branch 113 are the second transverse flow guide branch 121 and the third transverse flow guide branch 121 from top to bottom. The uppermost adsorption hole 131 is located at one end of the first transverse flow guide branch 121 located in the main body 111. The middle adsorption hole 131 is located on the second type of arc segment 1222 of the longitudinal flow guide branch 122. The lowermost adsorption hole 131 is located at one end of the third transverse flow guide branch 121 located in the main body 111.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
