In order to solve the problem, the utility model provides a workbench.

[0026] As shown in Figure 1 and Figure 2 An embodiment of the utility model provides a workbench, which comprises a table plate 1 and a jacking mechanism 2, the top surface of the table plate 1 is suitable for placing a board, a plurality of jacking holes penetrating along the thickness direction of the table plate 1 are arranged, the jacking mechanism 2 comprises a jacking drive part and a plurality of jacking parts 25, the plurality of jacking parts 25 are one-to-one corresponding to the plurality of jacking holes, and the jacking drive part can drive each jacking part 25 to lift in the corresponding jacking hole; when the plurality of jacking parts 25 extend out of the jacking hole, the board on the table plate 1 can be jacked up.

[0027] Specifically, the processing equipment uses a mechanical hand to load and unload the workbench, when loading, the jacking drive part of the jacking mechanism 2 drives the plurality of jacking parts 25 to retract in the jacking hole, so that the top end of the jacking part 25 is lower than the top surface of the table plate 1, the clamping jaw of the mechanical hand clamps the board to be processed and places the board to be processed on the top surface of the table plate 1, and the processing equipment processes the board to be processed on the workbench. When unloading, the clamping jaw of the mechanical hand is accurately positioned above the processed board after receiving a signal, at the same time, the jacking mechanism 2 is immediately started, the jacking drive part drives the plurality of jacking parts 25 to extend out of the jacking hole, so that the top end surface of the jacking part 25 is higher than the top surface of the table plate 1 and abuts against the bottom surface of the processed board, the jacking part 25 jacks up the processed board to separate from the supporting surface, to provide operation space for the clamping jaw of the mechanical hand, the clamping jaw of the mechanical hand easily clamps the processed board to move or process, the seamless connection of the series of work not only shows the maturity and advancement of automation technology, but also greatly improves production, reduces operation difficulty, reduces physical damage caused by the clamping jaw to the board, such as scratching or bending, and provides favorable guarantee for accurate processing of the board.

When the plurality of jacking parts 25 extend out of the jacking hole, the top end of the jacking part 25 can abut against the bottom surface of the plate placed on the table plate 1, and jack up the plate to separate from the table plate 1, so that there is a space between the plate and the table plate 1 for the clamping jaw of the mechanical hand to operate, so as to facilitate the clamping jaw of the mechanical hand to clamp the plate.
