The picking and placing mechanism (5) further comprises a buffer piece (59), the buffer piece (59) is sleeved on the negative pressure piece (54), the negative pressure piece (54) is arranged on the mounting plate (53) in a sliding penetrating mode, one end of the buffer piece (59) is arranged in a butt joint mode with the mounting plate (53), and the other end of the buffer piece is arranged in a butt joint mode with one end, close to the workbench (1), of the negative pressure piece (54).
13. The lamination device according to claim 8, characterized in that the pick-and-place mechanism (5) further comprises a first detection member (58) and a second detection member (510), the first detection member (58) and the second detection member (510) being mounted at intervals on the mounting plate (53); any detection piece is arranged as a photoelectric sensor;
the first detection distance of the first detection member (58) is smaller than the second detection distance of the second detection member (510).
14. Lamination device according to claim 9, further comprising a control assembly electrically coupled to the air intake assembly, the shaping mechanism (3), the sliding mechanism (4) and the pick-and-place mechanism (5);
the control assembly comprises a PLC (programmable logic controller) board (71), a touch screen (72) and a switch module, wherein the touch screen (72) and the switch module are respectively and electrically connected with the PLC board (71).
15. A method of using a lamination apparatus as defined in any one of claims 1 to 14, the method comprising:
shaping and positioning: the negative pressing piece (54) is matched with the picking and placing mechanism (5) to drive the negative pressing piece (54) so as to adsorb the sheet (8) and transport the sheet (8) into the positioning cavity, the negative pressing piece (54) is separated from the adsorption sheet (8) and enters the positioning cavity through the shaping mechanism (3) to be abutted against the shaping sheet (8);
lamination: the negative pressing piece (54) is driven by the sliding mechanism (4) and the picking and placing mechanism (5) in a matched mode, so that the negative pressing piece (54) conveys the sheet (8) from the positioning cavity to the lamination cavity;
the shaping and positioning and lamination of the plates (8) are repeated to complete the lamination operation of the plurality of plates (8).
16. A microchannel heat exchanger obtained by the method of use of the lamination apparatus of claim 15; the microchannel heat exchanger comprises a plurality of plates (8), and etching channels (81) are formed in the end faces of at least part of the plates (8).
