In use, the fixed baffle 50, the telescopic baffle device 60, the lifting baffle device 70 and the lifting and pushing baffle device 80 fix the piano product 100 from four directions before laser marking.

[0025] A support structure 20 and a conveyor roller 40 are installed on the frame 10. The conveyor roller 40 is used to convey piano products. The piano product 100 is fixed from four directions by a fixed baffle 50, a telescopic baffle device 60, a lifting baffle device 70 and a lifting and pushing baffle device 80. Laser marking is then performed to achieve automatic positioning marking. The marked piano product 100 can continue to move downstream along the conveyor roller 40, thereby improving production efficiency.

[0026] In a preferred solution, the conveying roller 40 can rotate under the drive of a motor, so as to convey the piano product 100. Specifically, the conveying roller 40 adopts a powered roller conveyor. For example, a double-sprocket powered roller conveyor for food conveying disclosed in CN204751235U is adopted. When used, the roller channel steel bracket is installed on the top plate 11 of the frame 10.

[0027] The fixed baffle 50 is fixed on the top plate 11 of the frame 10 as one of the limit references, and the lifting baffle device 70 is used as the second limit reference.

[0028] In a preferred embodiment, see Figure 1-3 , so that the laser marking machine 30 can move flexibly, and the processing system can mark at different positions of the piano product 100. The support structure 20 is a three-dimensional slide module structure, which includes an X-axis module 21, a Y-axis module 23 and a Z-axis module 25. The two X-axis modules 21 are respectively installed on the left and right sides of the frame 10, and the two ends of the Y-axis module 23 are respectively installed on the X-axis modules 21 on both sides through the connecting column 22.

[0029] The three-dimensional slide module structure is a prior art. For example, CN210546119U discloses a four-axis gantry robot structure. When applied to this patent, the two Y axes are installed on both sides of the top plate 11, and the laser marking machine 30 is installed on the Z axis.

[0030] In the preferred solution, the telescopic baffle device 60 is a cylinder with a simple structure. Figure 1 , 2 When the center height of the cylinder is not enough, a support is installed on the top plate 11 to raise it, and the cylinder is installed on the support to adjust the center of the cylinder.

[0031] Preferably, the telescopic baffle device 60 adopts a double-axis cylinder.

The telescopic end of the third push rod device 86 is telescopic, thereby driving the horizontal push baffle 87 to move. When the telescopic end of the third push rod device 86 is retracted, the horizontal push baffle 87 abuts against the piano product 100.

[0047] Afterwards, see Figure 2 The telescopic end of the telescopic baffle device 60 extends out to push the piano product 100, and the piano product 100 is close to the fixed baffle 50.

[0048] Afterwards, see Figure 3 , 5 , the telescopic end of the second push rod device 82 extends out, and at the same time, the telescopic end of the third push rod device 86 is in an extended state, the lifting plate 84 rises, and at the same time drives the third push rod device 86 and the push baffle 87 to move up, and the push baffle 87 is higher than the conveying roller 40, and then the telescopic end of the third push rod device 86 retracts, and the push baffle 87 positions the piano product 100 through the pad 871.
