[0039] The cleaning mechanism 60 includes a scraper 61 that moves along the y direction below the cavity 321 and a fifth driving device 62 for driving the scraper 61 to move along the y direction. A discharge hole is provided at one end of the chassis 10, and the discharge hole is located at the end of the moving direction of the scraper 61.

[0040] The panel splitter of this embodiment is provided with a first driving device 21 for driving the cutting device 23 to move along the x-direction and a second driving device 22 for driving the cutting device 23 to move along the z-direction, and a third driving device 31 for driving the carrier 32 to move along the y-direction. Through the linkage of the three driving devices, arbitrary adjustment of the cutting position is achieved.

In order to enable the cover plate 52 to press the entire circuit board 100 placed in the cavity 321, an electric lock (not shown) is further provided at the slot 322. The electric lock is used to lock the block 523 to prevent the cover plate 52 from loosening, so that the cover plate 52 can stably press the entire circuit board 100 placed in the cavity 321, thereby preventing the entire circuit board 100 from being offset and ensuring the subsequent cutting accuracy.

[0050] After cutting, the fifth driving device 62 is used to drive the pad 41 to withdraw from the cavity 321, so that the slag 102 formed after cutting can fall below the cavity 321, and finally the fifth driving device 62 drives the scraper 61 to push the slag 102 to the discharge hole for discharge. The action of the fifth driving device 62 driving the scraper 61 can be referred to Figure 7 shown.
