Description

Technical Field

[0001] The utility model relates to the technical field of transfer structures, in particular to a pallet module transfer and positioning mechanism. Background Art

[0002] In the new energy industry, battery modules are usually placed on pallets and transported to various workstations via conveyor lines. The pallet and module are then lifted as a whole by the lifting and positioning mechanism within the workstation for operation. For larger modules, due to the larger span of external dimensions and heavier overall weight, the modules may become skewed after lifting and positioning due to the consistency of each pallet and the guide clearance of the four guide shafts of the lifting mechanism. This makes it difficult to ensure the geometric and positional tolerance accuracy requirements of each module after lifting and positioning.

[0003] After the pallet and module are transported into place through the line, the pallet and module are lifted as a whole by the lifting and positioning mechanism. Due to the influence of the consistency of the pallet and the lifting guide gap, the stability and positioning accuracy of the module lifting are difficult to guarantee and the equipment cost is high, especially when the module length is long.

[0004] In addition, as customers are increasingly demanding on production efficiency, in some workstations with higher cycle times, the speed of the line conveying is difficult to increase after reaching a certain level, and the work efficiency cannot meet customer requirements.

The roller rack drives the transfer and jacking assembly to translate toward the first conveyor line. The first jacking plate translates from the material removal notch to the bottom of the pallet. The first jacking cylinder drives the first jacking plate to synchronously lift the pallet and module off the first conveyor line and then move them back to the positioning platform. The first jacking cylinder retracts and places the pallet and module on the positioning platform. During the descent, the pallet avoids the positioning support plate and module support block and is placed directly on the upper plate surface of the second pallet support plate and positioned by the pallet positioning pins. The module is supported by the module support block. At this time, due to the height difference, the module has already been separated from the pallet surface. The module positioning platforms on both sides clamp the module from both sides through lifting and translation (while aligning the module). After the module processing (such as welding) is completed, the clamping force on both sides is released. The transfer and jacking assembly lifts the pallet and module again and transfers them to the second conveyor line for unloading or transfer to the next workstation.
