Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

The precise positioning and pressurizing device of the board splicing machine shown in fig. 1 comprises a workpiece table 10, a pressure plate 20 and a pressure plate 20 driving mechanism, wherein the workpiece table 10 is used for placing boards. Specifically, the pressing plate 20 is disposed above the workpiece table 10, and the pressing plate 20 can move toward or away from the workpiece table 10 along the height direction of the worktable under the driving of the driving mechanism of the pressing plate 20. In addition, an elastic tube 21 is provided on the bottom end surface of the pressing plate 20, the extending direction of the elastic tube 21 is the same as the moving direction of the workpiece, and after the pressing plate 20 moves toward the workpiece table 10, the elastic tube 21 can abut on the plurality of plate materials of the workpiece table 10.

On the basis of the structure, use the utility model discloses a during accurate positioning pressure device of makeup machine, can place the less panel of each width of treating the concatenation on workpiece table 10, the less back is put in proper order at the workpiece table to the less panel of each width, can glue between two adjacent panels, glue the seam alright extend along the length direction of panel self that forms between two adjacent panels, glue the seam promptly and extend along the self length direction of work piece, and each panel glues in the direction of motion of work piece.

At this moment, the pressing plate 20 is driven by the pressing plate 20 driving mechanism to move downwards, the elastic tube 21 extending in the moving direction of the workpiece is in contact with the plates, namely the extending direction of the elastic tube 21 is perpendicular to the glue seam direction of the plates, the elastic tube 21 can be in compression joint with the glue seam between every two adjacent plates, and the elastic tube 21 pressing on the glue seam is one section because the extending direction of the elastic tube 21 is perpendicular to the extending direction of the glue seam, so that the contact area between the pressing plate 20 and the glue seam can be reduced, the pollution of glue is reduced, meanwhile, enough points are in contact with materials, and the material joint is ensured to be flush.

In addition, because the elastic tube 21 can have a certain deformation, the compensation can be carried out in the thickness direction, namely under the condition that the thickness change of the plate is small, the compensation can be carried out through the elastic tube 21 without utilizing a driving mechanism of the pressure plate 20, and the accurate positioning and crimping can be realized.

Further, the elastic tube 21 in this embodiment is made of teflon, i.e., can be selected as the teflon tube in the prior art, and because the teflon material has better lubricity and glue-proof property, the glue solution can be prevented from being stuck on the teflon tube after crimping, which is convenient for the crimping operation in the later period.
