DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] When the existing knife-type board splitter cuts PCBs and waste materials between different rows of PCBs, it often requires two passes, which is inefficient.

[0032] To this end, the present invention provides a cutting device for electronic components with a disc knife, see Figure 1 , which includes a bottom plate 1, which is in a square shape (it can also be round or other shapes), and a conveyor 7 is fixedly provided on the bottom plate 1. The conveyor 7 can transport the cut PCB to an external container to temporarily store the cut PCB. A frame 2 is fixedly provided at the top center of the bottom plate 1. The frame 2 is a prior art and can drive a driving device and a cutting mechanism 3 to move along the front and rear directions. A driving device is installed on the top of the inner wall of the frame 2. A cutting mechanism 3 for cutting PCB is provided at the output end of the driving device. The driving device can drive the cutting mechanism 3 to rotate. When the frame 2 drives the driving device and the cutting mechanism 3 to move, the driving device drives the cutting part on the cutting mechanism 3 to rotate to achieve the purpose of cutting PCB. A bottom side of the inner wall of the frame 2 is provided There is a feeding mechanism 4 for unloading the PCB after cutting. After the cutting mechanism 3 cuts off a row of PCBs, the row of PCBs falls on the feeding mechanism 4, and the feeding mechanism 4 is used to send the row of PCBs to the conveyor 7. A supporting mechanism 5 for supporting the PCB is provided on the other side of the bottom of the inner wall of the frame 2. The supporting mechanism 5 supports the part to be cut on the PCB circuit board to avoid the cutting by the cutting mechanism 3 so that the cutting process can proceed smoothly, and the waste between different rows of PCBs falls on the inner side of the supporting mechanism 5, and the waste is collected. A pushing mechanism 6 for pushing the PCB to move to the bottom of the cutting mechanism 3 is provided at one end of the top of the bottom plate 1. The pushing mechanism 6 continuously pushes the PCB circuit board to the bottom of the cutting mechanism 3 to wait for cutting;

[0033] The cutting mechanism 3 includes a first connecting block 301 fixedly matched with the output end of the driving device, see Figure 2 A fixing rod 302 is fixed at the center of one side of the first connecting block 301, and a gear 303 is rotatably provided at one end of the fixing rod 302. A grooved plate 304 is fixed at the bottom end of one side of the first connecting block 301. A rack 305 meshing with the bottom of the gear 303 is fixed to the inner wall of the grooved plate 304 by a plurality of bolts. The rack 305 can be separated from the grooved plate 304 by loosening the bolts, so that the rack 305 can slide along the inner wall of the grooved plate 304 to drive the gear 303 to rotate. The rack 305 can be fixed to the grooved plate 304 to prevent the gear 303 from rotating by tightening the bolts. Figure 3-4, a plurality of arc-shaped through holes are provided on one side of the gear 303, and the number of the arc-shaped through holes is 4 in total, which can also be determined separately according to actual conditions. A first connecting rod 306 is slidably provided on the inner wall of the arc-shaped through hole, and a fixed plate 307 is fixedly provided at the center of the fixed rod 302. A plurality of first sliding grooves are provided on the outer wall of the fixed plate 307, and the number of the first sliding grooves is 4 in total, which is always the same as the number of the arc-shaped through holes. A plurality of sliders 308 fixedly matched with one end of the first connecting rod 306 are slidably provided in the first sliding groove, and an arc-shaped clamping block 309 is fixedly provided at one end of the slider 308. When the gear 303 rotates, it means that the arc-shaped through hole rotates with the gear 303, thereby driving the first connecting rod 306 to move radially along the first sliding groove, thereby driving the slider 308 to slide along the inner wall of the first sliding groove, thereby driving the arc clamping block 309 to expand or retract with the fixed rod 302 as the axis; refer to Figure 2 and Figure 8 The outer wall of the arc-shaped clamping block 309 is provided with a plurality of slots, two of which are connected with a plug-in block 310, and the outer wall of the plug-in block 310 on the same side is clamped with a disc cutter 311. Multiple plug-in blocks 310 on the same side can be clamped with one disc cutter 311, and when the plug-in blocks 310 on the same side are respectively inserted into the corresponding slots, the distance between the two disc cutters 311 can be adjusted according to the different widths of waste in different PCB circuit boards, so that a row of PCBs and the corresponding waste can be cut off at one time.

[0034] For further information, see Figure 8 A second connecting block 312 is fixedly arranged at the other end of the fixed rod 302, and a plurality of limiting grooves are opened on one side of the second connecting block 312. The number of limiting grooves is 4 in total, and can also be determined separately according to actual conditions. A plurality of second connecting rods 313 are fixedly arranged on one side of the slider 308, and a movable block that slides with the limiting groove is fixedly arranged at one end of the second connecting rod 313. When the slider 308 moves with the first connecting rod 306, it also drives the second connecting rod 313 to move radially along the first sliding groove, thereby driving the movable block to slide along the inner wall of the limiting groove, so that the structural stability of the slider 308 and the arc-shaped clamping block 309 is stronger when moving.

[0035] See also Figure 5 and Fig. 9The support mechanism 5 includes a mounting plate 501 fixedly matched with the other side of the bottom of the inner wall of the frame 2. A plurality of grooves are provided on the top of the mounting plate 501, wherein two grooves are plugged with support plates 502. The number of grooves is set to an odd number, and the number of grooves can adjust the support plate 502 several times to meet the waste width in different PCB circuit boards. A through hole is provided on one side of the support plate 502, and an inclined plate 503 is rotatably provided inside the through hole. The waste cut by the disc cutting knife 311 falls between the two support plates 502 and on the inclined plate 503. The waste slides downward along the surface of the inclined plate 503 and passes through. Through the through hole, a plurality of mounting grooves are provided on the upward side of the inclined plate 503, and a roller 505 is rotatably provided in the mounting groove.

When the blanking plate 404 moves in the horizontal direction, the second cylinder 405 is started to extend or shorten it, and the blanking plate 404 is also driven to move, so that the blanking plate 404 is kept parallel to the horizontal plane or at an acute angle, so as to avoid the blanking plate 404 blocking the movement of the PCB circuit board, and facilitate the cutting operation of the PCB circuit board that is always in a horizontal state. When the cut PCB falls on the blanking plate 404, the second cylinder 405 is started again to extend it, driving the blanking plate 404 to rotate, so that the inclination angle of the blanking plate 404 is larger, so that the material falling on the blanking plate 404 continues to fall along the blanking plate 404 until it falls on the continuously rotating conveyor 7, thereby completing the unloading of the PCB.

[0037] See also Figure 7 The pushing mechanism 6 includes a mounting frame 601 fixedly matched with one end of the top of the bottom plate 1, an opening is opened in the center of the top of the mounting frame 601, and support bars 602 are symmetrically fixed on both sides of the top of the mounting frame 601, and the PCB circuit board is stuck between the two support bars 602. When the PCB circuit board moves, it will not separate from the support bar 602; a third cylinder 603 is fixedly provided on one side of the support bar 602 through a fourth fixed block, and a fifth fixed block is fixedly provided on the output end of the third cylinder 603. A clamping plate 604 for clamping and fixing the PCB is fixedly provided on one side of the fifth fixed block. When the disc cutting knife 311 is ready to cut a row of PCBs and waste, the third cylinder 603 is started to shorten it, driving the fifth fixed block and the clamping plate 604 to move downward, clamping and limiting the PCB circuit board, and preventing the PCB circuit board from shaking during cutting.

[0038] For further information, see Figure 7Sixth fixing blocks 605 are symmetrically fixed at both ends of the bottom of the mounting frame 601, and a motor 606 is fixedly installed on one side of one of the sixth fixing blocks 605. The output end of the motor 606 passes through the sixth fixing block 605 and is fixed with a screw 607 that rotates with another side of the sixth fixing block 605. The rotation of the motor 606 can drive the screw 607 to rotate. The surface of the screw 607 is threaded with an internal thread block 608. The top of the internal thread block 608 is fixed with a mounting block 609 that slides with the opening through a third connecting block. The rotation of the screw 607 drives the internal thread block 608 to move in the left and right directions, thereby driving the mounting block 6 09 slides along the opening, a fourth cylinder 610 is fixedly provided on the top of the mounting block 609, a push plate 611 for pushing the PCB is fixedly provided at the output end of the fourth cylinder 610, the fourth cylinder 610 is shortened to drive the push plate 611 to move downward, so that other external equipment can transport the new PCB circuit board to between the two support bars 602, the mounting block 609 is moved to drive the fourth cylinder 610 and the push plate 611 to move, the push plate 611 contacts the end face of the PCB circuit board, so that the push plate 611 continuously pushes the PCB circuit board to the bottom of the disc cutting knife 311, waiting for the disc cutting knife 311 to cut the PCB circuit board.

[0039] Working principle: When it is necessary to cut the PCB circuit board, the motor 606 is used to rotate and drive the push plate 611 to move. After the push plate 611 contacts the PCB circuit board, it drives the PCB circuit board to move until a row of PCBs to be cut moves through the two support plates 502. At this time, the V grooves (V grooves are a special groove structure, mainly used to separate the circuit board into smaller sub-boards, which is a prior art and will not be repeated) on both sides of the bottom of the waste corresponding to the row of PCBs are respectively engaged with the tops of the two support plates 502, and then the third cylinder 603 is used to drive the clamping plate 604 to move downward to the PC B circuit board is limited; then the frame 2 is used to drive the two disc cutting knives 311 to move from one side of the PCB circuit board to the other side. During this process, the electric disc cutting knife 311 of the driving device rotates to cut off the PCB sub-board, and cuts off the waste between the PCB sub-board and the next PCB sub-board waiting to be cut. The cut waste falls on the inclined plate 503 and slides downward along the inclined plate 503 and falls into the waste box 504. Then the second cylinder 405 is started to extend it, driving the unloading plate 404 to move downward, so that the PCB sub-board fallen on the unloading plate 404 slides downward and falls on the conveyor 7.
