[0001] The utility model relates to the field of plate processing and fixing, in particular to a multi-size plate fixing device. Background Art

[0002] The plates need to be fixed during processing to ensure the accuracy of the processing. The existing processing methods mostly use vacuum adsorption pads to adsorb and fix the plates. Such a structure will not limit the size of the plates, so that plates of various sizes can be fixed on the processing table by vacuum adsorption. However, during the processing, the debris generated by the processing can easily remain on the processing table, causing the debris to clog the holes on the pad, thereby reducing the vacuum adsorption strength at a certain position and reducing the overall adsorption effect on the plate. After long-term use, it is easy to affect the fixing effect of the plate, thereby affecting the accuracy of the plate processing. Utility Model Content

[0006] Furthermore, a plurality of support columns are provided in the negative pressure chamber, and the bottom of the porous adsorption plate is in contact with the top of the support columns.

[0007] Furthermore, an air passage communicating with the negative pressure chamber is provided inside the support column, the air passage vertically penetrates the upper and lower ends of the support column, and a plurality of penetrating vents are provided on the side walls of the air passage.

[0008] Furthermore, the sum of the lengths of the cleaning rods on both sides is equal to the width of the processing table.

[0009] Furthermore, the power assembly includes a motor and gears, the motor is fixed on the gantry, the gears are two meshingly connected, and the two gears are respectively fixed on the output shaft of the motor and the end of the cleaning rod.

[0010] Furthermore, the top of the cleaning rod is rotatably connected to a supporting wheel.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The structure of the utility model is to set a negative pressure chamber on the processing table. The negative pressure chamber generates negative pressure through the negative pressure tube at the bottom. The porous adsorption plate covered on the top of the negative pressure chamber generates negative pressure on the top of the porous adsorption plate. When the plate is placed on the porous adsorption plate, it can produce an adsorption and fixing effect on the plate, and will not limit the size of the plate.

When the plate is unloaded after processing, the cleaning rods on both sides are driven by the power assembly to rotate to a horizontal direction, so that the dust removal nozzles face the table top of the porous adsorption plate. As the gantry moves, the dust removal nozzles can quickly clean and adsorb the debris remaining on the porous adsorption plate, reducing the phenomenon that the holes of the porous adsorption plate are blocked by debris and the adsorption effect is reduced. The structure is simple, the debris is cleaned more cleanly and thoroughly, the stability of the plate during processing is ensured, and the accuracy of plate processing is improved.

The dust removal nozzles 9 are opened when the cleaning rod 6 is rotated to the horizontal When the plate is processed, it faces the top of the porous adsorption plate 4, so that the gantry 5 can drive the horizontal cleaning rod 6 to move after the plate is processed, so that multiple dust removal nozzles 9 can simultaneously adsorb and clean the debris remaining on the porous adsorption plate 4 to avoid clogging the holes of the porous adsorption plate 4, thereby ensuring the adsorption effect on the plate.

[0026] Preferably, refer to Figure 3 The top of the cleaning rod 6 is rotatably connected to a support wheel 15 through a bearing. When the cleaning rod 6 rotates to the horizontal direction, the support wheel 15 rolls in contact with the top of the porous adsorption plate 4.
