Each first suction cup 43 comprises a suction nozzle for sucking the light guide plate module 9; each second suction cup 44 includes two suction nozzles for sucking two individual light guide plates 91 cut by each light guide plate module 9.
In the present invention, one of the lower cutter head beams 52 is fixed, the second sliding module 541 is mounted at the bottom of the other lower cutter head beam 52, and the spacing adjustment driving motor 543 drives the lower cutter head beam 52 to approach or separate from the other lower cutter head beam 52 through the second sliding module 541 so as to adjust the spacing between the two lower cutter head beams 52, and simultaneously, the third sliding module 55 is driven to adjust the spacing between the two upper cutter head beams 51 through the linkage action of the first sliding module 532.

The lower parts of the two lower cutter head beams 52 are also provided with waste guiding grooves 10, and after the water gap connecting pieces 92 are cut off by the cutter mechanism 6, the water gap connecting pieces 92 fall into the waste guiding grooves 10 between the two lower cutter head beams 52 and are discharged out of the cutter.
The second rotating shaft hole 6125 is designed as a waist-shaped hole, and the upper cutter 611 moves towards the upper cutter adjusting frame 612 due to the fact that the upper cutter 611 is pressed by force in the descending process of the upper cutter 611, so that the rotating shaft 613 moves in the waist-shaped hole. The first elastic element 614 and the second elastic element 615 adopt springs, and when no external force acts on the upper cutter head 611, the upper cutter head 611 is in a forward tilting state under the action of the first elastic element 614 and the second elastic element 615 (as shown in fig. 5, the upper part of the upper cutter head 611 is far away from the upper cutter head adjusting frame 612, and the lower part is close to the upper cutter head adjusting frame 612). As shown in fig. 14, when the transfer device 4 transfers the light guide plate module 9 to the cutter mechanism 6, the position to be cut is placed at the edge of the lower cutter head 62, and each two upper cutter head modules 61 and each two lower cutter heads 62 are a group; the vertical end sides of the U-shaped notch structures of the two lower cutter heads 62 tension the two single light guide plates 91 in the direction indicated by the arrow of A, B, C, D, respectively, and then the two positioning and clamping mechanisms 57 clamp the light guide plate module 9 from the two outer sides of the light guide plate module 9 in the direction indicated by the arrow of E, F.
The upper end of the lower blade 62 is provided with an inclined chamfer on the side of the upper blade 611 adjacent to the upper blade 611 to ensure that the blade of the upper blade 611 is not in contact with the lower blade 62 during the just descent, and the middle of the upper blade 611 is in contact with the lower blade 62 first during the continued descent. The boss 616 is integrally formed on the rear surface of the upper bit 611.
The T-shaped transverse end of the upper tool bit mounting frame 617 is provided with a waist-shaped hole, and the waist-shaped hole is detachably connected with the top of the upper tool bit adjusting frame 612, so that the relative position of the upper tool bit adjusting frame 612 and the upper tool bit cross beam 51 can be adjusted through the waist-shaped hole, and the position of the upper tool bit 611 can be adjusted.
Meanwhile, the positioning pins 618 are designed as screws which are screwed with the ears 6171 of the upper bit mount 617. In the process of adjusting the upper cutter head 611, in the state that the upper cutter head mounting frame 617 and the upper cutter head adjusting frame 612 are not locked, the end portions of the positioning nails 618 are abutted against the back surface of the upper cutter head adjusting frame 612 so as to push the upper cutter head adjusting frame 612 (through the waist-shaped holes on the upper cutter head mounting frame 617) to be close to the back surface of the upper cutter head 611 until the positioning boss 6121 can be tightly attached to the back surface of the upper cutter head 611 under the condition that the upper cutter head 611 is tightly attached to the lower cutter head 62, so that the upper cutter head 611 is prevented from leaning backwards when cutting encounters resistance (the upper part is close to the upper cutter head adjusting frame 612, and the lower part is far away from the upper cutter head adjusting frame 612).
As shown in fig. 5, the upper cutter head 611 is shown in a schematic view before being lowered:
under the action of external force, the distance between the upper part of the protruding part 616 and the upper tool bit adjusting frame 612 by the second elastic part 615 is greater than the distance between the lower part of the protruding part 616 and the upper tool bit adjusting frame 612 by the first elastic part 614, and the whole upper tool bit 611 is in a forward tilting state (the upper part of the upper tool bit 611 is far away from the upper tool bit adjusting frame 612, and the lower part is close to the upper tool bit adjusting frame 612).
As shown in fig. 6, the upper cutter head 611 is shown in a schematic configuration during the lowering process (before cutting):
because the side of the lower cutter head 62 near the upper cutter head 611 is provided with an inclined chamfer, the lower cutter head 62 is not contacted with the upper cutter head 611 in the initial stage of descent, and the middle part of the front surface of the upper cutter head 611 is contacted with the lower cutter head 62 firstly in the gradual descent process.
As shown in fig. 7, the front surface of the upper tool bit 611 is fully contacted with the lower tool bit 62:
the upper cutter head 611 continues to descend, so that the upper part of the front surface of the upper cutter head 611 is extruded by the lower cutter head 62 to retreat until the whole upper cutter head 611 is in a vertical state; at this time, the upper blade 611 is entirely pushed by the lower blade 62 and retreats, and the rotary shaft 613 moves backward on the second rotary shaft hole 6125 (waist-shaped hole).
When the upper cutter head 611 descends to cut materials, the upper cutter head 611 is likely to lean backwards due to cutting resistance (the upper part of the upper cutter head 611 is close to the upper cutter head adjusting frame 612, and the lower part of the upper cutter head 611 is far away from the upper cutter head adjusting frame 612), and at the moment, the positioning bosses 6121 on two sides of the upper part of the front surface of the upper cutter head adjusting frame 612 can abut against the back surface of the upper cutter head 611 to prevent the upper cutter head 611 from leaning backwards, so that the problem of low cutting precision of the materials caused by the fact that the upper cutter head 611 leans backwards is avoided.
The working process of the cutting machine is as follows:
1) The lifting device 2 drives the material carrying device 3 to lift to the upper end of the lifting device 2, and the external manipulator places the first light guide plate module 9 on the material carrying platform 31 and is limited by the four limiting blocks 32;
2) The lifting device 2 drives the material carrying device 3 to descend to the top of the frame 1, and the rotary driving cylinder 71 in the rotary device 7 drives the material carrying platform 31 to drive the material to rotate for 90 degrees for positioning (the rotary angle can be set according to the requirement, and whether the rotary device 7 is started or not can be determined according to the requirement);
3) The first sucking disc 43 transfers the first light guide plate module 9 from the material loading platform 31 to two lower cutter heads 62 of the same group;
4) The interval adjusting driving motor 543 drives the adjusting screw rods 542 to drive the corresponding lower cutter head cross beams 52 to move, and adjusts the interval between the two lower cutter head cross beams 52 so as to tension the two inner sides of the first light guide plate module 9 outwards;
5) The positioning driving cylinder 571 drives the two positioning plates 572 to clamp the first light guide plate module 9 from both outer sides of the first light guide plate module 9;
6) The upper cutter head module 61 descends to cut the water gap connecting piece 92 of the first light guide plate module 9;
7) After the cutting is completed, the second sucker 44 of the transfer device 4 transfers the single light guide plate 91 cut from the first light guide plate module 9 to the conveyor mechanism, the single light guide plate 91 is stacked on the conveyor mechanism, and when the number in each stack reaches the set number (such as 20 single light guide plates 91 are stacked in each stack), the conveyor mechanism is driven forward for a certain distance; the first suction cup 43 transfers the second light guide plate module 9 from the loading platform 31 to the cutter mechanism 6 for cutting while the second suction cup 44 transfers the single light guide plate 91 cut by the first light guide plate module 9 to the conveyor mechanism.
The foregoing description of the preferred embodiment of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
