[0039] Embodiment 1

[0040] This embodiment provides a copper clad laminate wheel cutting device, as Figures 1 to 11 shown, which includes a frame 1, a support assembly 2, two sets of material pressing assemblies 3 and two sets of wheel cutting assemblies 4; the support assembly 2 is connected to the frame 1; the two sets of material pressing assemblies 3 are respectively arranged on both sides of the support assembly 2 in the transverse direction and are used to press the material on the support assembly 2; the two sets of wheel cutting assemblies 4 are respectively arranged on both sides of the support assembly 2 in the transverse direction and can move along the longitudinal direction. Each set of wheel cutting assemblies 4 includes two wheel cutting knives 41, one above the other, and the two wheel cutting knives 41 are staggered from each other to form a shearing gap.

[0041] The copper clad laminate wheel cutting device provided in this embodiment is used. When the copper clad laminate is placed on the top of the support component 2, the pressing component 3 then presses both sides of the copper clad laminate firmly on the support component 2, and then the wheel cutting component 4 moves in the longitudinal direction to cut both sides of the copper clad laminate with the help of the shearing action of the shear gap. Compared with the prior art, the cutting edge is smooth if the wheel cutting method is used. This copper clad laminate wheel cutting device can provide higher cutting quality.

[0042] In this embodiment, the width of the support assembly 2 in the lateral direction is adjustable; the pressing assembly 3 and the wheel cutting assembly 4 can both move in the lateral direction on the frame 1. When facing copper clad laminates of different sizes, the support assembly 2 can adjust its width to adapt to copper clad laminates of different sizes. At the same time, the pressing assembly 3 and the wheel cutting assembly 4 move together to adapt to copper clad laminates of different sizes.

[0043] In this embodiment, the support assembly 2 includes a fixed bearing platform 21 fixedly connected to the frame 1 and movable bearing platforms 22 respectively located on both sides of the fixed bearing platform 21 in the lateral direction, and the movable bearing platform 22 is connected to the frame 1 along the lateral sliding direction; the intersection of the movable bearing platform 22 and the fixed bearing platform 21 is spliced ​​by a comb-tooth-shaped structure. Based on the above structure, the width adjustment of the support assembly 2 is achieved by sliding the movable bearing platform 22. At the same time, the comb-tooth-shaped splicing structure can minimize the concavity of the copper clad laminate due to excessive gap after the movable bearing platform 22 leaves the fixed bearing platform 21. Preferably, the fixed bearing platform 21 is also provided with a suction cup, which can absorb the copper clad laminate and prevent the copper clad laminate from being offset when being cut.

[0044] In this embodiment, a carrier platform driving mechanism 13 is provided on the frame 1, and the carrier platform driving mechanism 13 is specifically a driving belt, which is arranged in a closed loop. Two movable carrier platforms 22 are slidably connected to the frame 1, and the two movable carrier platforms 22 are respectively connected to the driving belt. When the driving belt rotates, the two movable carrier platforms 22 synchronously approach or move away from each other.

[0045] In this embodiment, the material pressing assembly 3 and the wheel cutting assembly 4 located on the same side are connected to the same sliding seat 11, and the sliding seat 11 is connected to the frame 1 in a lateral sliding manner; the material pressing assembly 3 includes a gantry 31 connected to the sliding seat 11 and a lifting and lowering pressure block 32 connected to the crossbeam of the gantry 31; the wheel cutting assembly 4 is connected to the sliding seat 11 in a longitudinal sliding manner. Preferably, the frame 1 is provided with a transverse slide rail extending in the transverse direction, the sliding seat 11 is slidably connected to the transverse slide rail, and a sliding seat driving mechanism 14 is provided between the frame 1 and the sliding seat 11, specifically a screw nut mechanism extending in the transverse direction. At the same time, the sliding seat 11 is provided with a longitudinal slide rail extending in the longitudinal direction, the wheel cutting assembly 4 is slidably connected to the longitudinal slide rail, the wheel cutting assembly 4 is provided with a gear driven by a motor, and the sliding seat 11 is provided with a rack extending in the longitudinal direction, and the gear is meshed with the rack.

[0046] Based on the above structure, the score-cutting steps of the copper clad laminate are as follows: The sliding seat 11 drives the material pressing assembly 3 and the score-cutting assembly 4 away from the support assembly 2 so that there is no obstruction above the support assembly 2; the two movable bearing platforms 22 of the support assembly 2 slide to adjust the total width of the support assembly 2; the copper clad laminate is placed on the support assembly 2 from above; the sliding seat 11 drives the material pressing assembly 3 and the score-cutting assembly 4 close to the support assembly 2; the material pressing assembly 3 presses the copper clad laminate on the movable bearing platform 22 and exposes the part to be cut; the score-cutting assembly 4 moves longitudinally, and the score-cutting knife 41 cuts the copper clad laminate.

[0047] In this embodiment, the frame 1 is further provided with a blanking conveying assembly 12. The blanking conveying assembly 12 is located below the support assembly 2. When the blanking at the edge of the copper clad laminate is cut out, it falls onto the blanking conveying assembly 12, and the blanking conveying assembly 12 conveys away the blanking.

[0048] In this embodiment, the size of the shearing gap between the two score-cutting knives 41 can be adjusted. When facing different copper clad laminates, the size of the shearing gap is adjusted to adapt to different copper clad laminates; when the score-cutting assembly 4 has a function of adjusting the shearing gap by itself, it is not necessary to replace it frequently, the hardware cost is low, and the adjustment is simple and fast, with little impact on production.

[0049] In this embodiment, the score-cutting assembly 4 includes a mounting seat 42, two groups of vertical adjustment mechanisms, two rotating shafts 43 and a transmission mechanism; the two rotating shafts 43 are respectively connected to the mounting seat 42 by means of the two groups of vertical adjustment mechanisms so that the distance between the two rotating shafts 43 in the vertical direction is adjustable; the transmission mechanism is in transmission connection with the two rotating shafts 43 and makes the two rotating shafts 43 rotate synchronously and reversely; the two score-cutting knives 41 are respectively fixedly connected to the two rotating shafts 43. That is, each score-cutting knife 41 is provided with a corresponding vertical adjustment mechanism so that each score-cutting knife 41 can be vertically adjusted relative to the mounting seat 42 independently.

[0050] In this embodiment, the vertical adjustment mechanism includes a vertical slider 457 which is slidably connected to the mounting base 42 in the vertical direction; the vertical slider 457 is provided with an inclined chute 458, and the mounting base 42 is provided with a horizontal chute 451. A horizontal slider 452 is slidably connected in the horizontal chute 451. The horizontal slider 452 is connected with a pressing block 453 which is slidably connected in the inclined chute 458. When the horizontal slider 452 slides horizontally, the pressing block 453 presses against the groove wall of the inclined chute 458 and causes the vertical slider 457 to slide vertically. The rotating shaft 43 is rotatably connected to the vertical slider 457. Based on the above structure, by moving the horizontal slider 452 in the horizontal direction, under the combined action of the inclined chute 458 and the pressing block 453, the vertical slider 457 slides in the up and down direction to realize the vertical adjustment of the wheel cutter 41. It can be understood that each vertical slider 457 is provided with an inclined chute 458, and two sets of horizontal chutes 451, horizontal sliders 452 and pressing blocks 453 that are paired with the inclined chute 458 are provided on the mounting base 42. The two vertical sliders 457 are vertically adjusted in the same manner respectively. Preferably, the pressing block 453 is a roller rotatably mounted on the horizontal slider 452. Using a roller can reduce friction and make the adjustment smoother.

[0051] In this embodiment, the mounting base 42 is provided with a horizontal through hole 454 extending from its side wall to the horizontal chute 451. An adjusting screw 455 is provided to pass through the horizontal through hole 454 and be screwed to the horizontal slider 452. A limiting block 456 for limiting the lateral position of the adjusting screw 455 is provided on the side wall of the mounting base 42. Based on the above structure, when it is necessary to slide the horizontal slider 452, by screwing the adjusting screw 455 outside the mounting base 42, under the action of the threaded connection, the horizontal slider 452 moves; at the same time, in order to limit the adjusting screw 455, the limiting block 456 is provided on the side wall of the mounting base 42. The limiting block 456 limits the position of the adjusting screw 455 so that it does not fall off, but the limiting block 456 does not prevent the adjusting screw 455 from rotating.

[0052] In summary, turning the adjusting screw 455 can make the vertical slider 457 slide up and down.

[0053] In this embodiment, a vertically arranged locking screw 459 is screwed onto the mounting base 42, and the vertically arranged locking screw 459 can abut against the top or bottom of the vertical slider 457. In order to enable the horizontal slider 452 to slide within the horizontal chute 451 and also enable the abutting block 453 to slide within the inclined chute 458, therefore, there needs to be a gap between the horizontal slider 452 and the horizontal chute 451, and there also needs to be a gap between the abutting block 453 and the inclined chute 458. The existence of the above gaps will cause the vertical slider 457 to slide slightly up and down relative to the mounting base 42, and such sliding is not convenient for subsequent precise positioning of the vertical slider 457. For this reason, a vertically arranged locking screw 459 is added in this embodiment. After the vertical slider 457 is adjusted in place, the vertically arranged locking screw 459 is used to abut against the vertical slider 457 to fix it, which is convenient for subsequent fixing of the vertical slider 457.

[0054] In this embodiment, the stability of vertically positioning the vertical slider 457 only by the above-mentioned abutting block 453 and the vertically arranged locking screw 459 is not high. For this reason, the vertical slider 457 is provided with a vertically elongated hole 4571, and the locking screw 459 passing through the vertically elongated hole 4571 is screwed onto the mounting base 42. Based on the above structure, the vertically elongated hole 4571 can provide a space for the vertical slider 457 to slide vertically. When it is necessary to adjust the vertical position of the vertical slider 457, first loosen the locking screw 459 passing through the vertically elongated hole 4571. After adjusting the vertical position of the vertical slider 457, tighten the locking screw 459 passing through the vertically elongated hole 4571 again, and the vertically elongated hole 4571 fixes the vertical slider 457 relative to the mounting base 42.

[0055] In this embodiment, the mounting seat 42 is provided with a dovetail slider extending in the vertical direction, and the vertical slider 457 is provided with a vertical slide groove. The dovetail slider is slidably connected to the vertical slide groove, and the cooperation between the vertical slide groove and the dovetail slider serves as a sliding guide for the vertical slider 457. In order to enable the vertical slide groove to slide on the dovetail slider, there needs to be a gap between the vertical slide groove and the dovetail slider. The existence of the above gap will cause the vertical slider 457 to deviate relative to the mounting seat 42. In order to improve stability, the gap should be eliminated after the vertical slider 457 is adjusted into place. To this end, in this embodiment, one of the groove walls of the vertical sliding groove is a vertical groove wall, and the other groove wall is a wedge-shaped groove wall. A wedge block is provided between the vertical groove wall and the dovetail slider, with the inclined surface of the wedge block facing the dovetail slider and the vertical surface of the wedge block facing the vertical groove wall. A locking screw 459 passing through the side wall 4572 of the vertical slider is provided and screwed to the side wall 4572 of the vertical slider, and the locking screw 459 passing through the side wall 4572 of the vertical slider abuts against the vertical surface of the wedge block. When the vertical position of the vertical slider 457 needs to be adjusted, the locking screw 459 passing through the side wall 4572 of the vertical slider is also loosened first. When the vertical slider 457 is adjusted to the right position, the locking screw 459 passing through the side wall 4572 of the vertical slider is tightened to abut against the wedge block and tighten the wedge block, so as to eliminate the above-mentioned gap and lock the vertical slider 457.

[0056] In this embodiment, the transmission mechanism includes a motor 441, which is transmission-connected to the first rotating shaft 43, a driving gear 442 is sleeved on the first rotating shaft 43, a driven gear 443 is sleeved on the second rotating shaft 43, a first transmission gear 444 and a second transmission gear 446 are sequentially connected between the driving gear 442 and the driven gear 443, and also includes a first swing arm 445 and a second swing arm 447; the first transmission gear 444 is rotationally connected to the first end of the first swing arm 445, and the second end of the first swing arm 445 is hinged to the mounting seat 42; the second transmission gear 446 is rotationally connected to the first end of the second swing arm 447, and the second end of the second swing arm 447 is hinged to the second rotating shaft 43; a swing arm abutting screw 448 is provided between the second swing arm 447 and the mounting seat 42, and the swing arm abutting screw 448 is used to abut the second swing arm 447 so that the driving gear 442, the first transmission gear 444, the second transmission gear 446 and the driven gear 443 are sequentially kept in meshing.

[0057] Based on the above structure, the rotation of the motor 441 drives the first rotating shaft 43 to rotate. Through the transmission of the gears, the second rotating shaft 43 rotates synchronously. Since the transmission passes through two gears during this process, the rotation directions of the two rotating shafts 43 are opposite. Since both rotating shafts 43 can move up and down, in order to prevent the gears from disengaging after the two rotating shafts 43 move up and down, two transmission gears are arranged on the rotatable swing arms, and swing arm abutment screws 448 are provided. After the two rotating shafts 43 move up and down, by adjusting the swing arm abutment screws 448, it can be ensured that the gears remain meshed.

[0058] In this embodiment, a shaft nut 431 for adjusting the position of the rotating shaft 43 relative to the mounting base 42 in the lateral direction is sleeved on at least one rotating shaft 43. The mounting base 42 is screwed with a rotating shaft abutment screw 432, and the rotating shaft abutment screw 432 can abut against the rotating shaft 43 along the lateral direction (i.e., the axial direction of the rotating shaft 43). The distance between the two rotating shafts 43 can be adjusted not only in the vertical direction but also preferably in the lateral direction to further adapt to different copper clad laminates. By loosening the shaft nut 431, the rotating shaft 43 can move relative to the mounting base 42 in the lateral direction. After moving to the required position, the shaft nut 431 is tightened again. Based on the above adjustment, the size of the shearing gap can be changed in the lateral direction (i.e., the axial direction of the rotating shaft 43) to adapt to different copper clad laminates. In actual use, only one of the rotating shafts 43 can be laterally adjustable, or both rotating shafts 43 can be laterally adjustable. The above replacements all fall within the protection scope of the present invention. The rotating shaft abutment screw 432 can abut against the rotating shaft 43 along the axial direction of the rotating shaft 43. When the lateral (i.e., the axial direction of the rotating shaft 43) position of the rotating shaft 43 needs to be adjusted, first loosen the shaft nut 431, then use the rotating shaft abutment screw 432 to abut against the rotating shaft 43 to a suitable position and keep abutting, and then tighten the shaft nuts 431 on the rotating shaft 43 in sequence, so as to realize the re-locking of the position of the rotating shaft 43 in the lateral direction, reducing the adjustment difficulty. Without the abutment of the rotating shaft abutment screw 432, when the shaft nut 431 is screwed, the rotating shaft 43 will move back and forth, making it difficult to position and with high adjustment difficulty.

[0059] Embodiment 2

[0060] In this embodiment, except that the structure of the vertical adjustment mechanism is different from that of Embodiment 1, the others are the same as Embodiment 1.

[0061] In this embodiment, as Figures 12 to 14As shown in the figure, the vertical adjustment mechanism includes a bushing 465. The bushing 465 is cylindrical and rotatably connected to the mounting base 42. The bushing 465 is provided with an eccentric shaft hole 466. The axis of the eccentric shaft hole 466 is parallel to the axis of the bushing 465 and the two axes are spaced apart by a certain distance. An annular rack 467 is provided on the outer periphery of the bushing 465. A regulating gear 468 is rotatably connected to the mounting base 42. The annular rack 467 meshes with the regulating gear 468. The rotating shaft 43 is rotatably connected to the eccentric shaft hole 466.

[0062] Based on the above structural arrangement, the rotating shaft 43 is installed through the bushing 465 with the eccentric shaft hole 466. When facing different copper clad laminates, rotate the bushing 465 by the same angle in the opposite direction. Under the action of the eccentric shaft hole 466, the two rotating shafts 43 move relative to each other to adjust the relative position of the two wheel cutters 41 in the vertical direction. Based on the above adjustment, the size of the shearing gap can be changed to adapt to different copper clad laminates.

[0063] In this embodiment, in order to facilitate the rotation of the bushing 465, an annular rack 467 is provided on the outer periphery of the bushing 465. A regulating gear 468 is rotatably connected to the mounting base 42. The annular rack 467 meshes with the regulating gear 468. By rotating the regulating gear 468, the bushing 465 can be rotated under the action of meshing transmission. Preferably, the mounting base 42 is provided with a through hole 461 for the bushing 465 to pass through. An annular accommodation groove 462 is provided on the outside of the through hole 461. A gear accommodation groove 463 is provided on the outside of the annular accommodation groove 462. The bushing 465 is rotatably connected to the through hole 461. The annular rack 467 is located in the annular accommodation groove 462. The regulating gear 468 is located in the gear accommodation groove 463. The mounting base 42 is connected with a cover plate 464 for the bushing 465 to pass through. The cover plate 464 covers the annular accommodation groove 462 and the gear accommodation groove 463 and forms an accommodation cavity. The annular rack 467 and the regulating gear 468 are both located in the accommodation cavity. Based on the above structure, the annular rack 467 and the regulating gear 468 are not exposed, avoiding sundries from entering and affecting meshing. The cover plate 464 is provided with an adjusting rod penetrating through its thickness direction. The adjusting rod is rotatably connected to the cover plate 464. One end of the adjusting rod located in the accommodation cavity is fixedly connected to the regulating gear 468. A bolt head 469 is provided at the end of the adjusting rod located outside the accommodation cavity. Based on the above structure, turning the bolt head 469 can rotate the bushing 465, which is convenient for operation.
