Detailed description of the invention
nullRefering to Fig. 1 to 4,A kind of many knife plate dividing machines preventing pcb board from deforming,Including underframe 1、Belt 5,The frame fixed structure of the generally internal hollow out of underframe 1,The top of underframe 1 is formed with a plane 14,A positioning guide rail 11 it is connected with in plane 14,The position, center of plane 14 has a rectangle square hole (not shown),The two ends of the rectangle square hole that positioning guide rail 11 location is fixed in plane 14,Coordinate on positioning guide rail 11 and a cutter sweep 4 is installed,Specifically,Cutter sweep 4 is the eight row's cutter groups being fixed in side by side on positioning guide rail 11,Equally spaced in the first row cutter group of cutter sweep 4 it is consolidated with blade 45 side by side,Can cut difficulty determines whether install blade 45 in first row cutter group according to the V-CUT groove on pcb board,Complete if the V-CUT groove on pcb board is once difficult to cutting,That cuts the 50% of V-CUT groove with regard to the blade 45 of first row cutter group,Then the blade 45 of cutter group ground from the groove that the blade 45 of first row cutter group cuts through the most side by side,Complete to cut 50% and the smoothing that V-CUT groove is last,Due to V-CUT groove only by the cutting of twice blade 45,Decrease a plurality of cutting-and creasing that cutting the most repeatedly stays,Make the pcb board edge more flat smooth that segmentation is good,Plate face is the most smooth,Cutter sweep 4 includes side fixed plate 41、Connecting plate 42、Power transmission shaft 43、Belt pulley 44、Blade 45,Side fixed plate 41 is fixed together with the end face outside of positioning guide rail 11,Connecting plate 42 is integrated with side fixed plate 41 consolidation,Power transmission shaft 43 cooperation is arranged on the axis of side fixed plate 41 medial surface,Further,Power transmission shaft 43 is two be distributed up and down,The pcb board shear stress that in moving process, upper and lower surface is subject in power transmission shaft 43 is to synchronize,So pcb board integral planar after singulation does not haves and is bent upwards or is bent downwardly,Belt pulley 44 is socketed on a lateral edges of power transmission shaft 43,Blade 45 is fixedly arranged on power transmission shaft 43,Preferably,Blade 45 is 13,Can disposably be divided into a plurality of pcb board,Improve the working (machining) efficiency of pcb board,Two blades 45 and the center line symmetrically structure along power transmission shaft 43 it is consolidated with on power transmission shaft 43,The the most inside equally spaced of blade 45 is fixed in step-like structure,It is consolidated with a blade 45 in last row's cutter group of cutter sweep 4,Pcb board is in cutting procedure,Both sides pcb board elder generation well cutting also offsets to both sides,The pcb board on both sides mutually will not extrude with middle pcb board,The edge of a plurality of pcb board will not tilt、Whole plane will not distort.
nullFurther,Side in plane 14 is fixedly connected with a charging flat board 2,The one side of charging flat board 2 is connected on the side of cutter sweep 4,It is installed with a driving motor 21 in charging flat board 2,A discharging mechanism 3 it is connected with on positioning guide rail 11,One end of discharging mechanism 3 is connected on the opposite side of cutter sweep 4,Coordinate on discharging mechanism 3 and a discharging power transmission shaft 31 is installed,Motor 21 is driven to be linked together with belt pulley 44 and discharging power transmission shaft 31 by belt 5,The inner side of plane 14 is connected with a rewinding case 12,The circumferential side frame of rewinding case 12 wraps the rectangle square hole in plane 14,The entirety of rewinding case 12 is in progressively downward closing-in structure,The bottom of rewinding case 12 is formed with a discharging opening 13,Motor 21 is driven to synchronize to drive belt pulley 44 to rotate with discharging power transmission shaft 31 by belt 5,Pcb board is fallen in rewinding case 12 by discharging power transmission shaft 31 drive after being split by blade 45,After collect together through discharging opening 13,Monoblock pcb board is through division processing,Become the molding fritter pcb board meeting dimensional requirement.
In sum, many knife plate dividing machines that the present invention prevents pcb board from deforming complete pcb board by blade cutting twice, decrease a plurality of cutting-and creasing that cutting the most repeatedly stays, make the pcb board edge more flat smooth that segmentation is good, plate face is the most smooth, simultaneously when pcb board removes last group blade, pcb board does not haves edge to both sides skew and tilts.
Embodiment described above is only to be described the preferred embodiment of the present invention, is not defined the spirit and scope of the present invention.On the premise of without departing from design concept of the present invention; various modification that technical scheme is made by this area ordinary person and improvement; protection scope of the present invention all should be dropped into, the technology contents that the present invention is claimed, all record in detail in the claims.
