Cooling conveyor system for a robot welding cell

The welded components need to undergo a cooling process during transportation to the subsequent station within a robot welding facility, allowing for subsequent slag removal. The products require approximately four minutes cooling time. This necessitates a conveyor system capable of transporting the products across both straight and curved sections. The placement of products on the cooling line is handled by a robot, while manual removal occurs at the end of the cooling line. Additionally, the design must ensure access to the interior of the plant for maintenance purposes, with the access area capable of being opened twice daily. The welding seam temperature will briefly reach 800 °C, and the products weigh between six to eight kilograms. The welding system achieves a throughput of two units per minute, and the conveyor must be resilient to the abrasive conditions 

The cooling line is constructed using multiple SBF-P flat top chain conveyors, featuring both curved and straight sections. A durable steel chain, designed to withstand the brief high temperatures of welding seams, serves as the transportation medium. With a conveyor speed of 5 m/min and the track layout, the welded components have ample time to cool down to an appropriate temperature. The ergonomic conveyor height of 800 mm facilitates easy removal of parts by workers at the end of the line. For access to the system’s interior, a foldable GUF-P 2000, equipped with a wire mesh belt for transportation, can be effortlessly swivelled upwards by 90° using handles.

Fast transportation of cylindrical battery cells in battery pack production

Cylindrical battery cells, each with a diameter of 46mm (height ranging from 80 to 120 mm) and weighing 0.3 kg per unit, are delivered to the goods-in department of an automotive manufacturer for battery pack production. In this department, robots batch-deliver the cells to the assembly process, arranging them on a belt conveyor.

On this conveyor, the DMC code of each cell needs to be scanned. Additionally, the cells undergo a cleaning process, visual inspection, and electrical testing to identify and separate defective units. Subsequently, the cells, now in an upright position, face a height difference of approximately 2500 mm to progress to the next processing stage in a position-oriented manner.

The transportation of these goods should be pallet-free, ensuring smooth flow, maximum throughput, and high process reliability.

The Versaflex A06 flat top chain conveyor system proves to be an optimal choice for the secure transportation of vertically oriented battery cells. In the horizontal segments, side rails with a 48 mm clearance effectively maintain the cells in an upright position, ensuring their proper alignment for subsequent process steps.

For inclined transport, a clamping conveyor, also referred to as a double-grip conveyor, emerges as the most effective solution. Two Versaflex A06 conveying tracks positioned directly opposite each other utilize flexible cams to laterally clamp the cells, facilitating their vertical transport to another level. The conveyor ascends rapidly and smoothly to a height of 3400 mm.

Operating at a speed of 480 mm/s (28 m/min), equivalent to a cycle time of 0.1 seconds per unit or a throughput of 600 cells per minute, the conveyor system covers a total conveying path length of approximately 20 m, including the horizontal sections before and after the incline. The utilization of a clamping device allows for bridging a substantial height difference over a relatively short distance through a steep incline.
