when the baking rack is in a storage state, the sliding plate, the spring structure, the hinge rod, the turnover plate, the fixed plate, the driving rod and the rack are located at the inner side positions of the side plates, the turnover plate is in a horizontal state, the hinge rod is in an upward turnover state, meanwhile, the bending part takes the third shaft lever as a shaft to enable the driving rod to be in an upward turnover state, the driven rod part is in a vertically placed state, the main body rod part is in a horizontally placed state, the spring structure is in a relatively shortened state, and correspondingly, the rack is in a horizontally placed state;
the baking rack is changed from the storage state to the unfolding state by the following steps: applying an acting force to the operating handle, driving the sliding plate to move outwards through the operating handle, and further enabling the sliding plate to move outwards along the sliding groove of the side plate, wherein in the first stage, the roller rolls on the supporting plate, and the turnover plate is attached to the supporting plate to move; then, the copper alloy plate enters a second stage, the roller leaves the supporting plate and enters the gap part, when the copper alloy plate enters the gap part, the supporting effect of the supporting plate on the roller is eliminated, correspondingly, the overturning plate is converted from horizontal placement to vertical placement and overturns downwards to move, the spring structure correspondingly extends the pull rope, meanwhile, the hinged rod moves downwards, meanwhile, the driving rod turns over, the driven rod part is converted from vertical placement to horizontal placement, the main body rod part is converted from horizontal placement to downwards overturned movement to vertical placement, meanwhile, the rack is driven to be in a vertical placement state, and the copper alloy plate is placed on the rack;
the baking rack is assembled from an unfolding state to a storage state and comprises the following steps: applying an acting force to the operating handle, and driving the sliding plate to move inwards through the operating handle so as to enable the sliding plate to move inwards along the sliding groove of the side plate; in the first stage, the roller moves in the notch part; then, the second stage is carried out, in this time, the roller is in contact with the supporting plate and moves onto the supporting plate, correspondingly, the turnover plate starts to be converted from the vertical state to the horizontal state, the spring structure is correspondingly compressed and shortened, meanwhile, the hinge rod moves upwards, meanwhile, the driving rod carries out turnover movement, the driven rod part is converted from the horizontal state to the vertical state, the main body rod part is converted from the vertical state to the horizontal state through upwards turnover movement, meanwhile, the frame is driven to be in the horizontal state, and the copper alloy plate is also converted from the vertical state to the horizontal state; at this moment, just accomodate the metal sheet that sprays the completion in the griddle, follow-up pushing the griddle into toasting the incasement and drying operation.
6. The treatment method for the rare earth nanoparticle-based copper alloy surface pretreatment device according to claim 5, wherein the frame comprises an upper cross bar and a lower cross bar, the upper cross bar and the lower cross bar are both connected to the driving bar, the upper cross bar is provided with an upper hook, and the lower cross bar is provided with a lower hook; the copper alloy plate is provided with an upper through hole and a lower through hole, the upper hook is hung in the upper through hole, and the lower hook is hung in the lower through hole;
each layer of the platform structure is provided with a group of the shelves, the upper shelf and the lower shelf are overlapped and placed, the upper shelf is positioned at the inner end of the lower shelf, and the copper alloy plate fixed on the upper shelf and the copper alloy plate fixed on the lower shelf are arranged at intervals and are not overlapped; the supporting plate is provided with a limiting rod;
the processing method comprises the following steps: when the baking rack is arranged from the storage state to the unfolding state, the copper alloy plate is hung on the upper cross rod and the lower cross rod; when the racks are sprayed, the spraying action is simultaneously carried out on the metal plates in the overlapping area, namely, the metal plates placed in the overlapping area of the upper rack and the lower rack are simultaneously sprayed; in addition, when the sliding plate touches the limiting rod during movement, the sliding plate stops moving.
