The pressing device is provided with a plurality of pressing devices, as shown in fig. 2, the pressing device comprises a pressing piece and a positioning frame 40, the positioning frame 40 comprises a fixed beam 41 and a positioning plate 42 for placing a guitar fingerboard, and the positioning plate 42 is arranged below the fixed beam 41. The jacking member is movably arranged on the fixed beam 41, and the top end of the jacking member can be clamped in the groove 31 of the cross beam 30. The transmission mechanism 60 is fixed on the frame 10, and the plurality of pressing devices are fixed on the transmission mechanism 60 along the length direction of the frame 10, when the guitar fingerboard is pressed, the transmission mechanism 60 can drive the pressing member to be separated from the groove 31, and drive the pressing devices to be conveyed forward.
On the basis of the structure, after the fingerboard is glued on the neck, if the fingerboard and the neck need to be pressed, the transmission mechanism 60 is started, and the transmission mechanism 60 drives the pressing device to move to the lower part of the cross beam 30, so that the top end of the top pressing piece is clamped in the groove 31 of the cross beam 30. The actuating mechanism 20 is actuated to move the cross member 30 upwardly to drive the ram upwardly so that a space is reserved between the ram and the positioning plate 42 for the guitar fingerboard and neck to be positioned toward the positioning plate 42. After the fingerboard and neck are placed on the alignment plate 42, the drive mechanism 20 is actuated to drive the cross member 30 downward, and the ram presses downward against the surface of the neck, thereby pressing the guitar fingerboard and neck against the alignment plate 42 for adhesive attachment. After the neck and the fingerboard are pressed against the positioning plate 42, the transmission mechanism 60 drives the pressing member to disengage from the recess 31 of the cross member 30 and drives the pressing device to forward, so that the neck and the fingerboard are further pressed and fixed during the transmission process. Because the transmission mechanism 60 is provided with a plurality of pressing devices, after the previous pressing device finishes the pressing of the neck and the fingerboard, the transmission mechanism 60 can transmit the next pressing device to the lower part of the beam 30 for pressing, thereby reducing the waiting time of operators and improving the working efficiency of pressing.
