Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): the PCB polishing-free cutting machine comprises a workbench (1), sliding chutes I (101) are arranged on two sides of the workbench (1), trays (2) and tool apron (4) are connected in the sliding chutes I (101), a supporting plate (3) is connected above the trays (2) through springs (202), sliding chutes II (201) are arranged on the periphery of the trays (2), movable positioning columns (6) are arranged in the sliding chutes II (201), a material conveying roller (7) is arranged on the outer side of the sliding chutes I (101), movable limiting blocks (702) are arranged in the material conveying roller (7), a strip-shaped blade (5) is connected in the middle of the tool apron (4) through bolts, a threaded hole (401) is arranged in the middle of the bottom of the tool apron (4), the threaded hole (401) is connected with a lead screw (15), two ends of the lead screw (15) are movably connected to the workbench (1), and lead screw (15) one end is connected with motor (14), and on motor (14) also were fixed in workstation (1), spout I (101) homonymy was equipped with longmen slide rail (8), and sliding connection had slide bar (9) on longmen slide rail (8), and sliding connection had Z axle slide rail (10) on slide bar (9) simultaneously, and Z axle slide rail (10) bottom is connected with pivot (12) through bearing (11), is equipped with hobbing cutter (13) on pivot (12).

During the use, push the guillootine with the PCB substrate through defeated material cylinder (7), fix a position through portable stopper (702), then descend Z axle slide rail (10), with hobbing cutter (13) contact PCB substrate to slowly descend Z axle slide rail (10) deepening and the contact depth of PCB substrate when drive hobbing cutter (13) are rolling. Meanwhile, before the hob (13) starts to contact the PCB base material, a motor (14) at the bottom is started to drive the tool apron (4) to enable the blade (5) to reach the designated cutting position.
