Description

Technical Field

[0001] The present invention relates to the technical field of tab processing, and in particular to a double-track linear production process for solid-state battery tabs. Background Art

[0002] At present, most of the pole lug production lines are single production lines, which complete the automated production of the pole lugs by gluing a single metal strip → heating multiple times → cutting into single plate-type pole lugs → chamfering the pole lugs. For example, the patent number is CN202122824474.6, which is a linear production line for power pole lugs. The production mode of this production line is that one material strip produces one pole lug. The average production cycle of a single pole lug is more than 7 seconds. The cost of a single device is high, and the production cycle time is long, making it difficult to adapt to the existing market. Summary of the invention

At the same time, the excess glue shoulder of the metal strip with glue is cut off to cut waste glue and ensure the size of the tape. Step 4: High-frequency heating is performed on the metal strip with adhesive, and the tab adhesive is heated again to heat the tab adhesive into a semi-liquid state so as to be better melted together with the metal strip; Step 5: cold press the metal strip with adhesive to ensure the flatness of the metal strip with adhesive, and the cooling water temperature is 18°C; then shape the metal strip with adhesive and fine-tune the flatness of the metal strip; Step 6: The metal strip with adhesive passes through the pulling device and the pressing device and enters the cutting device to be cut into plates; Step 7: After the cut tabs are positioned by the robot transport device to the double-piece positioning device, they are then transported to the chamfering device for chamfering. The chamfered parts are the finished power tabs.

The adhesive belts are unwound at the same time, and the pulling device and the pressing device cooperate to convey the metal belts to a fixed length; Step 2: The parallel metal strips enter the shaping, guiding and preheating device for shaping, guiding and preheating; the metal strips are glued by the glue drawing and gluing device to form two metal strips with glue, and the two metal strips with glue share a fixed-length adhesive tape, and the metal strips with glue are hot pressed and internally heated at least once; Step 3: The two metal tapes with glue that share the same fixed-length tape enter the glue separation and cutting device. A glue separation blade is set at the center of the cutting upper die, and position-adjustable glue cutting blades are set on both sides to cut the tab glue on the two metal tapes from the middle to form two independent metal tapes with glue. At the same time, the excess glue shoulders of the metal tapes with glue are cut off to ensure the size of the tapes. Step 4: High-frequency heating is performed on the metal strip with adhesive, and the tab adhesive is heated again to heat the tab adhesive into a semi-liquid state so as to be better melted together with the metal strip; Step 5: cold press the metal strip with adhesive, and the two cold pressing surfaces have a high degree of parallelism to ensure the flatness of the metal strip with adhesive; then shape the metal strip with adhesive and fine-tune the flatness of the metal strip; Step 6: The metal strip with adhesive passes through the pulling device and the pressing device and enters the cutting device to be cut into plates; Step 7: The cut tabs are transported by the robot to the double-piece positioning device for positioning, and then transported to the chamfering device for chamfering. After four chamferings, the finished power tabs are generated.
