It should be noted that the table body 2 in the prior art has the above functions, but in actual production, the requirements of the photovoltaic cell processing field on productivity are higher and higher, and the requirements of the cell production on the on-line process are higher and higher. For example, in the field of battery piece laser processing, the structure of the laser processing table is one of the key factors for stable machine operation and increased productivity. Because laser processing mesa and carousel connecting piece need locking screw, the carousel connecting piece is the locking of screw from the lower direction to laser processing mesa, and the benefit of doing so is that mesa top does not have big screw hole site, can distribute more regular vacuum gas pockets, reduces the remaining probability of piece. Because the high-power red light is used for processing the wafer, in the long-time laser processing process, the metal table surface for fixing the wafer can be gradually heated along with the increase of processing time, the temperature cannot be independently reduced, deformation processes such as creep deformation, fracture and stress relaxation are easy to occur after the metal expands with heat and contracts with cold, the flatness of the table surface is affected, the precision is deteriorated, and the stability of the processing effect is also deteriorated. Therefore, the table main body 2 in this embodiment is redesigned, so that on the basis of the function of adsorbing the workpiece, flowing water can enter the table main body 2 to cool the table main body 2, so as to achieve the effect of avoiding the influence on the processing precision caused by the continuous temperature rise of the table main body 2.
