Description

Technical Field

[0001] The utility model relates to the technical field of solid-state battery processing, in particular to a multi-track discharge device for solid-state battery tabs. Background Art

[0002] Before the solid-state battery tabs are formed, they are rolled metal strips, and rolled metal strips require an unwinding mechanism. The current unwinding method used is tension control, such as a unwinding correction device with patent number CN202122738551.6. This structure uses a magnetic powder clutch in conjunction with a drive motor to control the tension. The cost is high, there are constraints on the weight of the material strip, and frequent shutdowns for material replacement are required. It can only unwind one metal strip. A free unwinding correction device with patent number CN202321815761.3 no longer uses a magnetic powder clutch to control the tension and can carry 1.5 tons of raw materials. The mounting platform of the frame can freely unwind in high and low layers and can quickly replace raw materials without stopping the equipment. However, it can only unwind a single metal strip, and the production speed of the tabs is difficult to adapt to the existing market. Therefore, there is an urgent need to produce a multi-track unwinding device for solid-state battery tabs to discharge multiple metal strips at the same time and increase production capacity.

The two material trays are staggered left and right and are on the same horizontal line. The high-strength rubber sleeve is connected to a tensioning clamp assembly, and the two metal belts are respectively unwound from the unloading assembly and enter the material guiding assembly in parallel. The material guiding assembly is provided with a guide seat, a material pressing seat, a free material pulling seat, a free material pressing seat and a deviation correction sensing seat from front to back.

DETAILED DESCRIPTION

[0022] See also Figure 1-6 The present invention relates to a multi-track unloading device for solid-state battery tabs, including a unloading assembly and a guide assembly. The guide assembly is arranged at the rear side of the unloading assembly, and two metal strips 1 are unwound from the unloading assembly and enter the guide assembly. The unloading assembly includes an aluminum profile frame 2, a supporting bearing seat 3, a long inflatable shaft 4, a short inflatable shaft 5, a tensioning clamp assembly 6, an excellent rubber sleeve 7 and a material tray 8. The aluminum profile frame 2 is provided with a long inflatable shaft 4 and a short inflatable shaft 5 side by side in the front and back. One end of the long inflatable shaft 4 and the short inflatable shaft 5 is sleeved with an excellent rubber sleeve 7, and the other end is respectively connected to a material tray 8. The metal strip 1 is wrapped around the material tray 8. The two material trays 8 are staggered left and right and on the same horizontal line. The long inflatable shaft 4 and the short inflatable shaft 5 are respectively rotatably supported on the crossbeam 2.1 of the aluminum profile frame 2 by the supporting bearing seat 3. The excellent rubber sleeve 7 is connected to the tensioning clamp assembly 6, and the tensioning clamp assembly 6 is fixed on the crossbeam 2.1 of the aluminum profile frame 2.

[0023] The tensioning hoop assembly 6 comprises an upper hoop 6.1, a lower hoop 6.2, a retaining ring 6.3, a pressure sensor 6.4, and a hoop fixing sleeve 6.5. The rubber sleeve 7 is sandwiched between the upper and lower hoops 6.1 and 6.2. The upper and lower hoops 6.1 and 6.2 are locked together by bolts. A pressure sensor 6.4 is mounted on one bolt between the upper and lower hoops 6.1 and 6.2, while a retaining ring 6.5 is mounted on the other bolt. The upper and lower hoops 6.1 and 6.2 lock the rubber sleeve 7. The locking force between the upper and lower hoops 6.1 and 6.2 is adjusted by the bolts. The specific locking value is determined by the pressure sensor 6.4 in the middle, thereby adjusting the friction between the rubber sleeve 7 and the corresponding air shaft to achieve tension adjustment of the tray. The retaining ring 6.3 is mounted on the ends of the long and short air shafts 4 and 5 to prevent the rubber sleeve 7 from slipping. The lower hoop 6.2 is supported and fixed on the crossbeam 2.1.

[0024] The material guiding assembly is provided with a guide seat 9, a material pressing seat 10, a free material pulling seat 11, a free material pressing seat 12 and a correction sensing seat 13 in sequence from front to back.

[0026] The free pulling seat 11 is driven by the pulling cylinder 16 to move laterally, which plays the role of fixed-length conveying and constant tension of the metal strip, so that the strip can be accurately conveyed in a fixed length and kept in a straight state. The metal strip 1 enters between the upper and lower pressing plates in the free pulling seat 11, and is pressed by the pressing cylinder. The metal strip enters between the upper and lower pressing plates in the free pressing seat 12, and is pressed by the pressing cylinder. The pressing cylinder and the pressing cylinder move intermittently.
