[0028] By arranging the adsorption assembly on the sliding mounting seat and cooperating with the pushing assembly, when the adsorption assembly carrying the auxiliary material on which the first release film is torn rotates to the pushing station, the pushing assembly can push the sliding mounting seat towards the attaching station, so as to drive the adsorption assembly on the sliding mounting seat to enter the attaching station, and then attach the auxiliary material on which the first release film is torn to the standing battery cell at the attaching station, thereby saving space.

[0040] When the sliding mounting base rotates to the pushing station, the limiting wheels on the sliding mounting base enter the arc-shaped slots of the pushing block through the gap, so that the limiting wheels are positioned. After the auxiliary material is pushed to the attaching station by the adsorption assembly, the pushing driving element drives the pushing block to slide back along the radial direction to the gap, so that the arc-shaped slots of the pushing block and the limiting slots form a circular slot body again, so that the sliding mounting base can rotate axially with the mounting plate. When the sliding mounting base continues to rotate, the limiting wheels on the sliding mounting base can smoothly slide back to the limiting slots from the arc-shaped slots of the pushing block, and the design is reasonable, the structure is compact, and the space is saved.

Since the base plate is provided with the anti-sticking piece, and the adsorption end of the suction cup is located in the opening hole of the anti-sticking piece, the suction cup does not contact the auxiliary material. Therefore, when the adsorption subassembly adsorbs the auxiliary material, the adsorption subassembly does not stick to the auxiliary material, and the transportation efficiency of the auxiliary material is improved.

[0086] Specifically, the sliding mounting seat 331 is slidingly installed on the mounting plate 330 through a sliding guide pair composed of a linear guide rail and a sliding block.

[0087] It can be seen that by arranging the adsorption assembly 34 on the sliding mounting seat 331 and cooperating with the pushing assembly 80, when the adsorption assembly 34 carrying the auxiliary material 21 completing the tearing of the first release film rotates to the pushing station 64, the pushing assembly 80 can push the sliding mounting seat 331 towards the attaching station 60, so as to drive the adsorption assembly 34 on the sliding mounting seat 331 to enter the attaching station 60, and then attach the auxiliary material 21 completing the tearing of the first release film on the vertical battery cell 70 at the attaching station 60, so that the structure is compact and space-saving.

[0091] It can be seen that by arranging four stations on the rotating path of the adsorption assembly 34, there is one adsorption assembly 34 at the receiving station 62, the second film tearing station 63, the pushing station 64 and the idle station 65 at the same time, and the remaining three adsorption assemblies 34 can respectively implement the receiving, film tearing and pushing out of the three auxiliary materials 21 at the respective processing stations, which speeds up the work rhythm and improves the work efficiency. At the same time, by arranging the idle station 65, when the adsorption assembly 34 of another station is damaged, the adsorption assembly 34 of the idle station 65 can replace the damaged adsorption assembly 34 to work, which has high fault tolerance.

[0093] Specifically, the pushing driving member 81 is a pneumatic cylinder.

[0094] It can be seen that through the cooperation of the pushing driving member 81, the pushing block 82, the limiting wheel 332 and the limiting groove 350, when the sliding mounting seat 331 rotates to the pushing station 64, the limiting wheel 332 on the sliding mounting seat 331 enters the arc-shaped groove of the pushing block 82 through the gap, so that the positioning of the limiting wheel 332 is realized. After the auxiliary material 21 is pushed to the attaching station 60 by the adsorption assembly 34, the pushing driving member 81 drives the pushing block 82 to slide back along the radial direction to the gap, so that the arc-shaped groove of the pushing block 82 and the limiting groove 350 form a circular groove body again, so as to facilitate the axial rotation of the sliding mounting seat 331 following the mounting plate 330; when the sliding mounting seat 331 continues to rotate, the limiting wheel 332 on the sliding mounting seat 331 can smoothly slide back to the limiting groove 350 from the arc-shaped groove of the pushing block 82, which is reasonable in design, compact in structure and saves space.

[0095] Please refer to Figure 2 and Figure 3 As an embodiment, the adsorption assembly 34 includes at least two adsorption subassemblies 340, and the at least two adsorption subassemblies 340 are arranged on the rotating support 33 in the first horizontal direction and are spaced apart from each other. Each adsorption subassembly 340 is configured to adsorb one auxiliary material 21.

[0096] It can be seen that by arranging the adsorption assembly 34 to include at least two adsorption subassemblies 340, when each adsorption subassembly 340 adsorbs one auxiliary material 21, the auxiliary material 21 is attached to at least two battery cells 70 at the same time, thereby improving the production efficiency.

[0097] As an embodiment, the adsorption assembly 34 includes at least two adsorption subassemblies 340, and the at least two adsorption subassemblies 340 are arranged on the rotating support 33 in the first horizontal direction and are spaced apart from each other. Each adsorption subassembly 340 is configured to adsorb one auxiliary material 21.

[0098] It can be seen that when the at least two adsorption subassemblies 340 adsorb one auxiliary material 21 together, the adsorption and attachment of the auxiliary material 21 with a large size are realized, thereby improving the compatibility of the adsorption assembly 34.

[0099] As an embodiment, the adsorption subassembly 340 includes a base plate 341, a plurality of suction cups 342 and an anti-sticking member 343. The base plate 341 is fixed on the rotating support 33, and the plurality of suction cups 342 are uniformly arranged on the base plate 341. The plurality of suction cups 342 suck the auxiliary material 21 through negative pressure. The anti-sticking member 343 is attached to one side of the base plate 341 where the suction cups 342 are arranged. The anti-sticking member 343 is provided with a hole for avoiding the suction cups 342, and the suction end of the suction cup 342 is located in the hole of the anti-sticking member 343.

[0100] It can be seen that the suction member 340 sucks the auxiliary material 21 to the substrate 341 through the negative pressure of the suction cup 342. Since the substrate 341 is provided with the anti-sticking member 343, and the suction end of the suction cup 342 is located in the opening of the anti-sticking member 343 and does not contact the auxiliary material 21, when the auxiliary material 21 is sucked, the suction member 340 will not be bonded with the auxiliary material 21, thereby improving the transportation efficiency of the auxiliary material 21.

[0101] As an embodiment, the auxiliary material 21 is a spacer or a tape.

[0102] It can be seen that by setting the auxiliary material 21 as a spacer or a tape, the spacer or the tape is automatically attached to the surface of the battery cell 70, which can meet different process requirements and has good versatility.

[0103] As shown in FIGS. 1 and 2, as an embodiment, the first film tearing mechanism 40 is further configured to detect the auxiliary material 21 attached to the surface of the battery cell 70 to determine whether the position of the auxiliary material 21 is at a preset position of the surface of the battery cell 70. Figure 1 Figure 2 As shown in FIGS. 1 and 2, as an embodiment, the first film tearing mechanism 40 is further configured to detect the auxiliary material 21 attached to the surface of the battery cell 70 to determine whether the position of the auxiliary material 21 is at a preset position of the surface of the battery cell 70.

[0104] Specifically, the camera is installed on the first film tearing mechanism 40. The camera takes a photo of the auxiliary material 21 attached to the surface of the battery cell 70, and then obtains the position information of the auxiliary material 21 on the surface of the battery cell 70 to determine whether the position of the auxiliary material 21 is at the preset position of the surface of the battery cell 70.

[0105] It can be seen that by detecting the auxiliary material 21 attached to the surface of the battery cell 70 through the first film tearing mechanism 40, the accuracy of the attachment position of the auxiliary material 21 is automatically detected, thereby ensuring the attachment quality of the auxiliary material 21.

[0106] As an embodiment, the conveying mechanism 10 adopts any one of a magnetic suspension conveying line, a chain plate conveying line or a belt conveying line.

[0107] It can be seen that by setting the conveying mechanism 10 to adopt any one of a magnetic suspension conveying line, a chain plate conveying line or a belt conveying line, the appropriate conveying line can be selected according to different application scenarios.

[0108] As shown in FIGS. 1 and 2, the general working principle of the battery cell processing device provided by the embodiments of the present application is as follows. Figures 1 to 6 S1, the conveying mechanism 10 vertically transports the battery cell 70 to the attachment station 60;

[0109] S2, the attachment mechanism 30 picks up the auxiliary material 21 to be attached conveyed by the feeding mechanism and attaches the auxiliary material 21 to be attached to the battery cell 70 standing in the attachment station 60;

[0110]

[0111] ​​S3, the conveying mechanism 10 conveys the battery cell 70 with the auxiliary material 21 attached to the first film tearing station 61;

[0112] S4, the first film tearing mechanism 40 tears off the second release film of the auxiliary material 21 on the battery cell 70 at the first film tearing station 61;

[0113] S5, the conveying mechanism 10 vertically conveys the attached battery cell 70 to the next process.

[0114] The battery cell processing device provided by the embodiment has the following advantages:

[0115] 1) During the process of attaching the auxiliary material 21 to the battery cell 70, the conveying mechanism 10 always keeps the battery cell 70 in a vertical state during the process, so that the battery cell 70 does not need to be erected again during subsequent assembly, simplifying the process of battery module assembly and improving production efficiency;

[0116] 2) Through the cooperation of the driving assembly 32, the rotating bracket 33 and the at least three suction assemblies 34, one suction assembly 34 exists at the receiving station 62, the second film tearing station 63 and the pushing station 64 at the same time, and the suction assemblies 34 of the three stations can simultaneously implement the receiving, film tearing and pushing of the auxiliary material 21 respectively, thereby speeding up the work rhythm and improving the work efficiency, and the overall structure is compact and occupies small space;

[0117] 3) By arranging the suction assembly 34 on the sliding mounting seat 331 and cooperating with the pushing assembly 80, when the suction assembly 34 carrying the auxiliary material 21 with the first release film torn off rotates to the pushing station 64, the pushing assembly 80 can push the sliding mounting seat 331 towards the attaching station 60 to drive the suction assembly 34 on the sliding mounting seat 331 to enter the attaching station 60, and then the auxiliary material 21 with the first release film torn off is attached to the vertical battery cell 70 at the attaching station 60, so that the structure is compact and space-saving;

[0118] 4) The cooperation of the limiting groove 350 and the limiting wheel 332 realizes that the limiting wheel 332 is limited in the limiting groove 350 during rotation, plays a role of rotation guide, and at the same time, prevents the sliding mounting seat 331 from producing radial sliding during rotation, and prevents the suction assembly 34 from producing radial movement, thereby improving the stability of the auxiliary material 21 during transportation between stations;

[0119] 5) By arranging the idle station 65, when the suction assembly 34 of one of the other stations is damaged, the suction assembly 34 of the idle station 65 can replace the damaged suction assembly 34 to work through adjustment, and the fault tolerance is high;

[0120] 6) The suction assembly can simultaneously and independently suction at least two small-sized auxiliary materials 21, and can also collectively suction one large-sized auxiliary material 21, and has good compatibility.

[0121] The foregoing merely illustrates the principles of the application and various modifications and alterations are possible without departing from the scope and spirit of the application. It is intended that the application be construed as including all such modifications and alterations.
