[0026] Example 1
[0027] The present embodiment provides a column-by-column and control-by-control pallet device, comprising a composite plate 11 on which a plurality of composite columns 3 are arranged in a matrix to form N columns of composite columns 3, and further comprising a pallet 1 and a sealing structure.
[0028] The tray 1 is arranged below the synthetic board 11. N accommodating cavities are provided on the tray 1. One accommodating cavity is used to accommodate a column of synthetic columns 3. An interface 5 for connecting to the interior of the accommodating cavity is provided on one side of the accommodating cavity. The N accommodating cavities correspond to the positions of the N columns of synthetic columns 3. One end of each column of synthetic columns 3 is located in a corresponding accommodating cavity. A sealing structure is provided between the tray 1 and the synthetic board 11, for forming a sealed connection between the tray 1 and the synthetic board 11, so that each accommodating cavity forms a sealed chamber.
[0029] The spacing between the tray 1's cavities, the row-to-row spacing of the synthesis columns 3 on the synthesis board 11, and the row-to-row spacing of the needles on the synthesizer's injection needle plate are all identical. After the tray 1 and synthesis board 11 are assembled and pressed together using a sealing structure, the injection needles inject liquid. At this point, each column of the tray 1 and synthesis board 11 forms a separate sealed space. A vacuum device allows for independent liquid extraction from each column of the synthesis board 11, enabling column-by-column control of injection and extraction within a single synthesis board 11.
[0030] In this embodiment, an opening is provided at the top of the accommodating cavity, and the four sides of the opening are sealed and connected to the synthetic board 11 .
[0031] The sealing structure includes a gasket 2 disposed between the tray 1 and the composite board 11. The gasket 2 is provided with N escape holes, the shape and position of which match the shape and position of the opening. The sealing interval of the gasket 2 is consistent with the interval of the cavity of the tray 1.
[0032] The tray 1, the sealing gasket 2 and the synthetic board 11 are installed in order from bottom to top. Since the spacing between the three parts forming the cavity is the same, the cavities isolated from each other are realized in columns.
[0033] In this embodiment, the tray 1 has 12 sealed cavities, each sealed cavity corresponds to the grid cavity of the sealing gasket 2. After installation, the sealing gasket 2 is installed exactly on the table top of the sealed cavity of the tray 1. The table top of the sealed cavity forms a limiting groove, and the width of the sealing gasket 2 is consistent with the width of the limiting groove.
[0034] Tray 1 has 12 sealed cavities, each corresponding to a column of composite board 11. Composite board 11 has 96 composite columns 3, arranged in rows of 12 and columns of 8. The rows and columns function identically and are interchangeable. Each sealed cavity in tray 1 corresponds to eight composite columns 3 on composite board 11.
[0035] After the pallet 1, sealing gasket 2 and synthetic board 11 are installed in order from bottom to top, the sealing gasket 2 is exactly located between the table surface forming the cavity of the pallet 1 and the distance between the two rows of synthetic columns 3 of the synthetic board 11. After pressurization, the pallet 1 and the synthetic board 11 can be kept sealed.
[0036] How to use this embodiment
[0037] In the working position, the tray 1, the sealing gasket 2 and the synthetic board 11 are assembled together and pressed tightly, and the injection needles on the injection needle plate correspond one-to-one to the synthetic columns 3 on the synthetic board 11. At this time, the tray 1 and each column of the synthetic board 11 form a separate sealed space, and the vacuum device can realize independent extraction of liquid from the 8 synthetic columns 3 in each column of the synthetic board 11, so that the synthetic columns 3 on a piece of synthetic board 11 can be synthesized by column.

[0039] The separate column and separate control pallet device provided in this embodiment is provided with a plurality of pressing blocks 7 on the pallet 1 in order to further achieve sealing of the pallet and the synthetic board while facilitating adjustment of the synthetic board. The pressing blocks 7 are detachably connected to the pallet 1 and are used to press the synthetic board 11.
[0040] When in use, the composite board 11 and the tray 1 are clamped by rotating the pressing block 7. During operation, the rows and columns of the composite boards 11 can be easily adjusted by rotating the pressing block 7, which facilitates the selection and replacement of multi-type and multi-batch synthesis.
[0041] Specifically, one end of the pressing block 7 is connected to a rotating rod, which is rotatably connected to the pressing block 7. The other end of the pressing block 7 is arranged on the side of the composite board 11 facing away from the pallet 1, and the rotating rod is threadedly connected to the pallet 1. In this embodiment, one end of the rotating rod is fixedly connected to the pressing block bolt 10, and the pallet 1 has a threaded hole, and the pressing block bolt 10 is threadedly connected to the threaded hole.
