[0035] Reference Figure 5 and Figure 6 As shown, in this embodiment: the auxiliary structure 4 includes a fixing seat 41, one side of the fixing seat 41 is fixedly connected to the machine body 1, and an insertion rod 42 is slidably penetrated by the side of the fixing seat 41, and a tension spring 43 is sleeved on the outside of the insertion rod 42, and the two ends of the tension spring 43 are fixedly connected to the insertion rod 42 and the fixing seat 41 respectively, and the insertion rod 42 away from the fixing seat 41 is rotatably connected to the pull ring 44, and the inner wall of the fixing seat 41 is fitted with a connecting plate 45, and the side of the connecting plate 45 is provided with a socket 49, and the socket 49 is adapted to the size of the insertion rod 42, and the side of the connecting plate 45 away from the fixing seat 41 is fixedly connected with a storage box 46. By setting the auxiliary structure 4, after the electrode is glued, it can be placed in the storage box 46, so that the electrode can be conveniently stored, and when the electrode needs to be uniformly transferred to the next workstation after the electrode is pressed and glued, the storage box 46 can be conveniently disassembled and assembled.

[0036] In embodiment 2, the end of the insertion rod 42 away from the pull ring 44 is fixedly connected to a guide block 48, and the guide block 48 has a conical structure. By arranging the guide block 48 with a conical structure at one end of the insertion rod 42, the effect of conveniently inserting the insertion rod 42 into the inside of the socket 49 is achieved. The inner wall of the storage box 46 is fixedly connected to a plurality of partitions 47, and the partitions 47 are evenly distributed on the inner wall of the storage box 46. By arranging a plurality of partitions 47 on the inner wall of the storage box 46, the space for placing the electrodes in the storage box 46 can be evenly distributed, so that the electrodes can be arranged in an orderly manner on the inner wall of the storage box 46.

[0037] When the glue sticking device is in use, a mechanism for automatically applying glue to the glue sticking die head 6 can be installed on the guide rail 9. When it is necessary to use this device to assist the battery electrode in the pressing and gluing operation, the electrode is first placed on the electrode bottom mold 8 that is not directly under the glue sticking die head 6. When the electrode is placed, the turntable 309 is rotated with the help of the anti-slip groove to make the turntable 309 drive the disc 306 to rotate. During the process of the turntable 309 rotating in the direction indicated by the arrow 311, the spring 303 will drive the fixed block 304 to always slide along the inner wall of the annular hole 307. At the same time, the fixed block 304 will move along the side of the rounded corner of the inner wall of the fixed hole 308 to the inner wall of the next fixed hole 308.

[0038] After the electrode is glued, it can be placed in the storage box 46, so that the electrode can be stored conveniently. When the electrode is pressed and glued, the electrode needs to be transferred to the next workstation. First, pull the pull ring 44 to drive the insertion rod 42 to separate from the insertion hole 49. When the insertion rod 42 is separated from the insertion hole 49, move the connecting plate 45 to separate from the inner wall of the fixing seat 41, and then move the storage box 46 to transfer the electrode inside it uniformly. When the electrode is removed from the storage box 46, move the storage box 46 to drive the connecting plate 45 to the inner wall of the fixing seat 41. The wall fits together. When the socket 49 on the connecting plate 45 is aligned with the insertion rod 42, the pull ring 44 is pulled to drive the insertion rod 42 to be inserted into the socket 49, and the installation limit of the storage box 46 can be completed. Among them, by providing a guide block 48 with a conical structure at one end of the insertion rod 42, the effect of conveniently inserting the insertion rod 42 into the inside of the socket 49 is achieved. In addition, by providing a plurality of partitions 47 on the inner wall of the storage box 46, the space for placing the electrodes in the storage box 46 can be evenly distributed, so that the electrodes can be arranged in an orderly manner on the inner wall of the storage box 46.
