[0039] Example 2

[0040] See also Figure 1 , Figure 2The cylindrical battery folding and encapsulating mechanism shown includes a sealing block 6, a spring 7, a final workpiece 4, a pre-finishing workpiece 2, a guide cylinder 5, an adhesive tape 3 and a battery core 1. The pre-finishing workpiece 2 is provided with a groove, and a through hole is provided below the groove. The final workpiece 4 is provided with a through hole, and the pre-finishing workpiece 2 is sleeved inside the through hole of the final workpiece 4, and the pre-finishing workpiece 2 can slide up and down in the final workpiece 4. A bayonet is provided on the top of the pre-finishing workpiece 2, and an extension corresponding to the bayonet is provided on the top of the final workpiece 4. Multiple bayonet are arranged around the top of the pre-finishing workpiece 2 at equal intervals. When the pre-finishing workpiece 2 is pressed below the top surface of the final workpiece 4, the extension can further press the adhesive tape 3 on the battery core 1 to ensure that the adhesive tape 3 can fit more closely on the collector plate. The guide cylinder 5 is located above the final workpiece 4, and a guide cavity corresponding to the pre-finishing workpiece 2 is provided on the guide cylinder 5. The battery core 1 is introduced into the folding and encapsulating mechanism through the guide cavity, and contacts and squeezes the pre-finishing workpiece 4. The caliber of the end of the pre-sizing workpiece 2 close to the guide cylinder decreases from top to bottom, and is used to fold and fit the tape 3 on the end face of the battery roll core 1 to the contact surface. The sealing block 6 is arranged below the pre-sizing workpiece 2, the spring 7 is arranged between the pre-sizing workpiece 2 and the sealing block 6, and the final workpiece 4 is installed above the sealing block 6. The spring can ensure that the pre-sizing workpiece 2 is automatically reset after being pressed down to ensure the next use. Specifically, a heating rod 8 is provided on the top of the final workpiece 4, and the heating rod 8 heats the final workpiece 4, so that the final workpiece 4 can melt the glue at high temperature while flattening the tape 3, thereby enhancing the fitting effect of the tape 3 and shaping it.

[0043] Specifically, the guide cylinder 5 is fixed above the final workpiece 4 by bolts.

[0044] Specifically, four springs 7 are arranged at equal intervals.

[0045] The working principle and use process of the utility model are as follows: the final workpiece is heated by a heating device. When the temperature sensing device senses that the temperature reaches the requirement, the heating is stopped, and the workpiece after gluing is passed from one end of the guide cylinder through the guide cavity into the mechanism. When the tape touches the pre-finished workpiece, the tape is compressed and folded under the action of the pre-finished workpiece. The battery core continues to press inward, squeezing the spring set between the pre-finished workpiece and the sealing block. When the squeezing reaches a certain degree, the battery core squeezes the top surface of the final workpiece, and further flattens the tape under the action of the final workpiece to ensure that the tape can fit tightly and beautifully on the collector plate. At the same time, the heated workpiece shapes the folded tape to further improve the fitting effect. After all the processes are completed, the workpiece is taken out and the spring automatically resets. The structure of the utility model is simple to use. It only needs to put the workpiece into the glue folding and encapsulating mechanism and press it to take it out. The operation steps are few and the glue folding efficiency can be improved. The glue folding effect is stable. It can reduce the risk of battery short circuit when used for battery core glue folding and encapsulating.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
