And a plurality of material trays 700 containing workpieces to be processed can be simultaneously fed and a plurality of material trays 700 stacked and containing processed workpieces can be simultaneously taken out through the cart 104, so that the labor intensity of workers is reduced.
In order to simplify the structural composition and facilitate maintenance, the first lifting assembly and the second lifting assembly are preferably configured to have the same structure.
Referring to fig. 8, in some embodiments, the material tray 700 has side plates 701 at both sides thereof, and upper and lower ends of the side plates 701 protrude with respect to the material tray 700, considering that a portion of the workpiece has a certain height. Can support material tray 700 through two curb plates 701 like this to make material tray 700 unsettled, when material tray 700 piles up to put like this, upper and lower adjacent work piece can not take place to interfere.
Correspondingly, in some embodiments, a support structure is disposed at the bottom of the cart 104 corresponding to each of the two side plates 701, and the material tray 700 is stacked on the support structure to keep the bottom suspended for the lifting assembly to function.
This bearing structure direct set up to two risers 106 can.
In some embodiments, the two side plates 701 have an extension structure protruding from the proximal end of the two support structures, and the first lifting assembly can extend between the two support structures when the cart 104 is located in the parking area 102 and act on the extension structure during the lifting process, thereby lifting the material tray 700.
The extension structure has various arrangement forms, such as that the inner walls of the side plates 701 (i.e. the near ends of the two side plates 701) shown in fig. 8 protrude relative to the inner wall of the support structure, and the first lifting assembly realizes the lifting of the material tray 700 by lifting the bottom of the side plates 701; for another example, a reinforcing rod is disposed between the two side plates 701, and the material tray 700 is lifted by lifting up the reinforcing rod. The specific implementation manners of the extension structure capable of achieving the above-mentioned functions are many and are not listed here.
In some embodiments, cart 104 is provided with a stop structure in the vertical direction, and material trays 700 are stacked on a support structure while keeping the bottom suspended and held in alignment up and down by abutting against the stop structure. The spacing structure is preferably arranged as two sets of vertical beams 105.
