At the same time, a set of jigs 7 at the bottom of the bare cell conveyor belt 6 is transferred to the top of the bare cell conveyor belt 6 for transferring the bare cells. After the bare cell in the heating box is qualified in temperature measurement, the bare cell is output by the bare cell conveyor belt 6, and the bare cell is grabbed by a feeding robot of the hot-press shaping machine 8.
The second abnormal procedure: when the hot press shaper 8 is in fault or overhauled or is stopped due to material blocking in a later procedure, the bare cell group on the feeding robot of the hot press shaper 8 is not turned to a hot press station due to overtime and is cooled. And the bare cell group is transferred into any one heating box of the two transfer devices by the feeding robot of the hot press shaper 8 for reheating. The bare cell group on the blanking robot of the preheating tunnel furnace 10 is transferred into another heating box for heating. After normal operation, the blanking robot of the preheating tunnel furnace 10 takes a new bare cell group from the preheating tunnel furnace 10 to the jig 7 on any bare cell conveyor belt 6 of the two transfer devices according to the normal flow, and the feeding robot of the hot press shaper 8 grabs the bare cell group for shaping, so that the production beat is not influenced. And bare cells heated by the heating box are available at any time.
It should be noted that, first, when the two heating boxes are both provided with the bare cell group for heating, it is required to meet that the parts of the two bare cell conveying belts 6 located outside the heating boxes are not provided with bare cells, the feeding robot of the hot press shaper 8 is also provided with bare cells, and the discharging robot of the preheating tunnel furnace 10 can newly take the bare cell group from the preheating tunnel furnace 10. Secondly, when one of the two heating boxes is provided with a bare cell for heating, the condition that the bare cell does not exist on the part of the two bare cell conveying belts 6 positioned outside the heating boxes is required, and the blanking robot of the preheating tunnel furnace 10 can newly take the bare cell group from the preheating tunnel furnace 10. Third, when the bare cell group is not heated by the two heating boxes, the bare cells can be freely grabbed by the blanking robot of the preheating tunnel furnace 10 and the feeding robot of the hot press shaper 8.
It will be appreciated by those skilled in the art that the present invention can be carried out in other embodiments without departing from the spirit or essential characteristics thereof. Accordingly, the above disclosed embodiments are illustrative in all respects, and not exclusive. All changes that come within the scope of the invention or equivalents thereto are intended to be embraced therein.
