A kind of many knife plate dividing machines for preventing pcb board from deforming
The present invention relates to a kind of many knife plate dividing machines for preventing pcb board from deforming.
Board separator is the sheet material larger for splitting length-width ratio, and board separator can reach the sheet material split when splitting sheet material
Flush edge is smooth, and plate face keeps smooth, so being widely applied in electronic product industry, easily becomes during especially for segmentation
Shape, the larger PCB plates of length-width ratio, but existing board separator is after the completion of segmentation, PCB plates remove one group of last cutter
During piece, the two blocks of adjacent PCB plates separated will not both sides skew, two blocks of adjacent PCB plates is occurred extrusion and collisions, sternly
Occur that PCB edges of boards edge tilts even whole planar distortion during weight, this can have a strong impact on electronics in later stage installation PCB plates and set
Standby overall assembling quality.

As a further improvement on the present invention, the entirety of the rewinding case is in progressively downward closing-in structure, the rewinding case
Bottom be formed with a discharging opening.
As a further improvement on the present invention, the motor passes through the belt and the belt pulley and the discharging
Power transmission shaft links together.
Beneficial effect：Compared with prior art, it has the advantages that the present invention：
The present invention prevents many knife plate dividing machines that pcb board is deformed from completing pcb board by blade cutting twice, reduces in the past many
The a plurality of cutting-and creasing that secondary cutting leaves, the pcb board edge more flat smooth for getting well segmentation, plate face is very smooth, together
When pcb board removes last group of blade, pcb board to both sides skew be not in edge tilt.

Refering to Fig. 1 to 4, a kind of many knife plate dividing machines for preventing pcb board from deforming, including underframe 1, belt 5, the entirety of underframe 1
For the frame fixed structure of internal hollow out, the top of underframe 1, which is formed with a plane 14, plane 14, is connected with a positioning guide rail
11, the center position of plane 14 is provided with a rectangle square hole（It is not shown）, positioning guide rail 11, which is positioned, is fixed in length in plane 14
Coordinate on the two ends of square square hole, positioning guide rail 11 and a cutter device 4 is installed, specifically, cutter device 4 is to be fixed in side by side
Blade 45 is consolidated with side by side at equal intervals in eight row's knife groups on positioning guide rail 11, the first row knife group of cutter device 4, can basis
V-CUT grooves on pcb board cut difficulty to determine whether install blade 45 in first row knife group, if the V-CUT grooves on pcb board
Once it is difficult to cutting to complete, that cuts the 50% of V-CUT grooves with regard to the blade 45 of first row knife group, then the knife of knife group side by side below
Ground in the groove that piece 45 is cut through from the blade 45 of first row knife group, and cutting V-CUT grooves last 50% and smoothing were completed, due to V-
CUT grooves reduce a plurality of cutting-and creasing that in the past multiple cutting leaves, make what segmentation was got well only by the cutting of blade 45 twice
Pcb board edge more flat smooth, plate face is very smooth, and cutter device 4 includes side fixed plate 41, connecting plate 42, power transmission shaft
43rd, belt pulley 44, blade 45, side fixed plate 41 and the end face outside of positioning guide rail 11 are fixed together, and connecting plate 42 is consolidated with side
The consolidation of fixed board 41 is integrated, and power transmission shaft 43 coordinates on the axis of the medial surface of side fixed plate 41, further, power transmission shaft 43
For up and down distribution two, the pcb board shear stress that upper and lower surface is subject in moving process in power transmission shaft 43 be it is synchronous, this
Integral planar is not in be bent upwards or be bent downwardly to sample pcb board after singulation, and belt pulley 44 is socketed in the one of power transmission shaft 43
On lateral edges, blade 45 is fixedly arranged on power transmission shaft 43, it is preferable that blade 45 is 13, can disposably be divided into a plurality of PCB
Plate, improves the processing efficiency of pcb board, two blades 45 are consolidated with power transmission shaft 43 and are in symmetrical junction along the center line of power transmission shaft 43
Structure, the generally inwardly fixed at equal intervals of blade 45 is in be consolidated with step-like structure, last row's knife group of cutter device 4
One blade 45, pcb board is in cutting procedure, and both sides pcb board elder generation well cutting is simultaneously offset to both sides, and the pcb board on both sides will not be with
Middle pcb board is mutually extruded, and the edge of a plurality of pcb board will not be tilted, whole plane will not be distorted.
Further, the side in plane 14 is fixedly connected with a charging flat board 2, and the one side of charging flat board 2, which is connected to, to be cut
On the side for cutting device 4, it is installed with charging flat board 2 on a motor 21, positioning guide rail 11 and is connected with a discharging machine
Structure 3, one end of discharging mechanism 3 is connected on the opposite side of cutter device 4, is coordinated on discharging mechanism 3 and is provided with discharging transmission
Axle 31, motor 21 is linked together by belt 5 with belt pulley 44 and discharging power transmission shaft 31, and the inner side of plane 14 is connected with
One rewinding case 12, the circumferential side frame of rewinding case 12 wraps the rectangle square hole in plane 14, and 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, and motor 21 drives belt pulley by the way that belt 5 is synchronous
44 are rotated with discharging power transmission shaft 31, and pcb board is driven by the power transmission shaft 31 that discharges after being finished by the segmentation of blade 45 and falls into rewinding case 12
It is interior, after be collected into together through discharging opening 13, monoblock pcb board passes through division processing, as meet size requirement shaping fritter
In summary, the present invention prevents many knife plate dividing machines that pcb board is deformed from completing pcb board by blade cutting twice, subtracts
The a plurality of cutting-and creasing that conventional multiple cutting leaves is lacked, the pcb board edge more flat smooth for getting well segmentation, plate face is non-
It is often smooth, while when pcb board removes last group of blade, pcb board is not in that edge is tilted to both sides skew.
