Description

Technical Field

[0001] The present invention relates to the technical field of substrate slitting and cutting, and particularly to a dust-free slitting and cutting machine for PCB cutting equipment. Background Art

[0002] In the production of PCB (printed circuit board), circuit boards using PP substrates (polypropylene substrates) usually have good mechanical strength, chemical stability and low cost, so they are widely used in many applications. For a dust-free slitting and cutting machine for such substrates, its design and function pay more attention to reducing the dust that may be generated during the cutting process, protecting the production environment, and ensuring cutting accuracy.

[0003] The patent with the publication number CN208946273U discloses a dust-free slitting device for CCL and PCB cutting equipment, including a fixed plate, a slide rail, a sliding frame, a mounting plate, a cylinder, a hot air shell, an air inlet pipe, a heating copper rod, a gas guide shell, a gas guide cavity, an exhaust shell, an air outlet hole, a slitting knife, a cylinder arm and a tool rest. This dust-free slitting device for CCL and PCB cutting equipment has a simple structure and novel design. The air in the hot air shell is heated by the heating copper rod, ensuring that the air in the hot air shell is discharged orderly through the air outlet holes on the surface of the air outlet shell, facilitating the treatment of the white edges at the cut-off parts of CCL and PCB boards. When in use, under the action of the set slitting mechanism, the CCL and PCB boards are automatically cut, greatly reducing the labor intensity of manual cutting by workers and improving the slitting efficiency of CCL and PCB boards. It has good market prospects and is suitable for popularization and use. However, this patent still has the problem that the cutting blade is prone to wear and is not easy to replace. Therefore, a dust-free slitting and cutting machine for PCB cutting equipment is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dust-free slitting and cutting machine for PCB cutting equipment in view of the above deficiencies in the prior art.

[0005] To solve the above technical problem, the technical solution adopted by the present invention is: a dust-free slitting and cutting machine for PCB cutting equipment, including a mounting plate, the top surface of the mounting plate is fixedly connected with a top plate, the top surface of the top plate is fixedly connected with a hydraulic rod, the bottom end of the hydraulic rod is fixedly connected with a lower pressing plate, and a cutting mechanism is arranged below the lower pressing plate;

[0006] The cutting mechanism includes two connecting rod fixing plates. Two vertical sliding rods are fixedly connected to the bottom surface of the connecting rod fixing plates. A lifting frame is slidably connected to the outer surface of the vertical sliding rods. Chute guide plates are arranged on both the front and rear sides of the lifting frame. A right moving frame and a left moving frame are respectively fixedly connected to the bottom surfaces of the two chute guide plates. A plurality of connecting frame fixing seats are fixedly connected to the sides of the left moving frame and the right moving frame. One end of each connecting frame fixing seat away from the right moving frame or the left moving frame is fixedly connected to a chuck end. A positioning shaft disc is rotatably connected to the inner side of the chuck end. A splicing chuck is fitted and connected to the side surface of the positioning shaft disc. A cutting disc is fixedly connected to the edge surface of the splicing chuck. A transmission key rod is slidably connected to the side surface of the positioning shaft disc.

[0007] According to the above technical solution, a linkage vertical rod is slidably connected to the side of the right moving frame or the left moving frame. A thin rod slider is fixedly connected to the bottom end of the linkage vertical rod. A guiding cross rod is slidably connected to the side surface of the thin rod slider. The lower right moving frame or the lower left moving frame is respectively arranged directly below the upper right moving frame or the upper left moving frame.

[0008] According to the above technical solution, the top surface of the lifting frame is fixedly connected to the lower pressing plate. A chute is provided on the side surface of the chute guide plate, and the chute is formed by connecting an inclined chute and a vertical chute. A convex column extends outward from the chute guide plate and is slidably connected to the chute guide plate. The guiding cross bar is fixedly connected to the mounting plate. The chuck ends on the left and right sides of each cutting disc are taken as a group. The right moving frame located below is fixedly connected to the thin rod slider on the same side. When installing the cutting disc, align the splicing chuck on the side surface of the cutting disc with the positioning shaft disc on one side of the chuck end, and make the splicing chuck and the positioning shaft disc fit together. Then, control the hydraulic rod to extend downward, and push the lifting frame connected to the lower pressing plate to slide downward along the vertical sliding rod. At this time, the lifting frame moves downward and pushes the chute on the side surface of the chute guide plate, so that the chute on the side surface of the chute guide plate drives the right moving frame and the left moving frame to move under force. When the right moving frame and the left moving frame move, the chuck end is driven by the connected connecting frame seat, so that the chuck ends on both sides in the same group approach each other, and drive the positioning shaft discs inside the chuck ends on both sides to clamp the splicing chuck on the side surface of the cutting disc. When the chuck ends connected to the right moving frame and the left moving frame approach each other, the transmission key rod connected to the chuck end slides with the positioning shaft disc. When an external motor drives the positioning shaft disc on the side surface of one chuck end to rotate, the positioning shaft disc on the side surface of this chuck end drives the other positioning shaft disc to rotate through the connected transmission key rod, and this positioning shaft disc drives the positioning shaft disc on the other side at the connected position to rotate through fitting with the splicing chuck, so as to realize the synchronous rotation of multiple positioning shaft discs driving the splicing chuck. As the hydraulic rod is in a continuous extension state, the lifting frame continues to move downward, and the chute guide plate connected to the lifting frame moves from the inclined side chute to the connected vertical chute. At this time, the lifting frame will push the chute guide plate to be stressed vertically and move downward. The downward movement of the chute guide plate will drive the right moving frame or the left moving frame to move downward along the connected linkage vertical rod, and make the right moving frame or the left moving frame above approach the right moving frame or the left moving frame below. In this way, the interval between the upper chuck end and the lower chuck end can be controlled to adjust the interval between the cutting discs to adjust the cutting thickness. The splicing chuck on the side surface of the cutting disc is clamped by the relative movement of the right moving frame and the left moving frame driving the chuck end to approach, so that the splicing chuck can be quickly fixed and installed, so as to be quickly replaced in case of wear later.

[0009] According to the above technical solution, a detection module is installed on the side surface of the cutting mechanism, a hot pressing mechanism is arranged on the front side of the cutting mechanism, a tensioning mechanism is arranged below the hot pressing mechanism. A support plate is fixedly connected to the front side surface of the right moving frame located below, a guiding roller is rotatably connected to the bottom end of the support plate, and a base material is arranged above the support plate.

[0010] According to the above technical solution, the detection module includes two connecting blocks, and the two connecting blocks are respectively fixedly connected to the front sides of the two chuck ends in the same group. One end of each of the two connecting blocks away from the chuck end is respectively fixedly connected with a power-on end and an alarm end. The power-on end and the alarm end are electrically connected to a power-on wire on the side. Elastic sheets are fixedly connected to the rear sides of the power-on end and the alarm end, and a metal contact piece is fixedly connected to the top surface of the elastic sheet. When the cutting disc is placed between the chuck ends, as the two chuck ends on both sides approach each other, the connecting blocks connected to the chuck ends on both sides of the same group respectively drive the power-on end and the alarm end to approach each other. The elastic sheets connected to the power-on end and the alarm end move together with them and fit against the side surface of the cutting disc. When the cutting disc wears and becomes thinner during use, the elastic sheets attached to both sides of the cutting disc will approach each other under the action of elasticity until the metal contact pieces connected to the elastic sheets approach and contact each other. At this time, the metal contact piece is in a conductive state with the buzzer built in the alarm end through the elastic sheet, and the buzzer built in the alarm end works.

[0011] According to the above technical solution, the hot pressing mechanism includes a hinge rod seat. A lower pressing hinge rod is rotatably connected to the inside of the hinge rod seat. A limiting block is fixedly connected to the bottom surface of the lower pressing hinge rod. An inclined groove rod is fixedly connected to the side surface of the lower pressing hinge rod. A sliding rod block is slidably connected to the outside of the inclined groove rod. A short hinge rod is rotatably connected to the side surface of the sliding rod block. One end of the short hinge rod away from the sliding rod block is hinged to a long hinge rod. The bottom side surface of the long hinge rod is hinged to a pressing plate. An electric heating tube is fixedly connected to the upper surface of the pressing plate. A short column is fixedly connected to the middle of the top surface of the rear end of the pressing plate. A deviation correcting shaft rod is rotatably connected to the outer surface of the short column. Deviation correcting wheels are rotatably connected to both ends of the deviation correcting shaft rod. A pressing wheel is rotatably connected to the bottom end of the lower pressing hinge rod.

[0012] According to the above technical solution, a return spring is arranged on the outer side of the inclined chute rod, and both ends of the return spring are fixedly connected to the slide rod block and the downward pressing hinge rod respectively. A torsion spring is arranged on the outer side of the short column, and both ends of the torsion spring are fixedly connected to the short column and the deviation correcting shaft rod respectively. There is damping between the downward pressing hinge rod and the hinge rod seat. When the upper right moving frame moves downward, the hinge rod seat connected to the right moving frame drives the downward pressing hinge rod to approach the pallet. When the pressing plate on the side of the downward pressing hinge rod fits the base material on the pallet, at this time, the pressing plate drives the slide rod block to slide along the short hinge rod and stretch the return spring through the force received by the extension plate slide rod connected thereto. At this time, the electric heating tube on the pressing plate transfers heat to the pressing plate through heating, and then transfers the heat to the base material through the contact between the pressing plate and the base material to heat the base material. By heating the pressing plate, the base material is kept flat, and the thermoplasticity of the material is increased by heating the base material, so that the cut of the base material is kept flat when being pressed and cut by the cutting disc, and dust generation during the cutting process is avoided by pressing and cutting. When the base material passes through the bottom surface of the pressing plate, the deviation correcting wheels at both ends of the pressing plate will guide the movement of the base material. When the base material deviates towards one of the deviation correcting wheels, the deviation correcting wheel will drive the deviation correcting shaft rod to deflect a small angle around the short column and twist the torsion spring under the force. At this time, the deflected deviation correcting wheel will deflect towards the side close to the right moving frame, and the deviation of the deviation correcting wheel is used to guide the base material to rotate away from the contacted deviation correcting wheel along with the pressing wheel, so that the base material is centered above the pallet.

[0013] According to the above technical solution, the tensioning mechanism includes a vertical guide rod, the bottom end of the vertical guide rod is slidably connected with an elastic extension rod, the bottom end of the elastic extension rod is fixedly connected with a pressing connecting rod, the outer surface of the pressing connecting rod is slidably connected with a deflection groove frame, the bottom end of the deflection groove frame is hinged with a pressing material arc plate, the front side of the pressing material arc plate is fixedly connected with an extension plate slide rod, the outer surface of the extension plate slide rod is slidably connected with an extension arc plate. A long connecting frame is fixedly connected to the bottom surface of the lower left moving frame, a short connecting frame is fixedly connected to the bottom surface of the lower right moving frame, a bracket plate is fixedly connected to the bottom surfaces of both the short connecting frame and the long connecting frame, a rotating shaft disc is rotatably connected to the bottom ends of both the short connecting frame and the long connecting frame, a keyway groove is formed on the side surface of the rotating shaft disc, and a coiled material wheel is arranged between the two rotating shaft discs, and convex bar shaft discs are fixedly connected to both ends of the coiled material wheel.

[0014] According to the above technical solution, the vertical guide rod is fixedly connected to the bottom surface of the lifting frame. An internal spring is provided inside the elastic extension rod, and both ends of the internal spring are fixedly connected to the vertical guide rod and the elastic extension rod respectively. A sliding rotating shaft is fixedly connected to the side surface of the deflection groove frame, and the sliding rotating shaft is slidably connected to the bracket plate. A tension spring is arranged outside the extension plate sliding rod, and both ends of the tension spring are respectively connected to the extended arc plate and the pressing material arc plate. The rotating shaft disk and the convex strip shaft disk are structurally fitted through the keyway groove. When the lifting frame moves downward, the lifting frame will drive the connected vertical guide rod and elastic extension rod to move downward together. Due to the large rigidity of the internal spring of the elastic extension rod, when the vertical guide rod is stressed, it will push the elastic extension rod downward through the internal spring, and the pressing link rod connected to the elastic extension rod will push the deflection groove frame. At this time, the deflection groove frame will deflect around the connection of the bracket plate. At this time, the deflection groove frame will lift the pressing material arc plate upward, so that the pressing material arc plate and the extended arc plate will jointly fit the base material outside the coil wheel. As the base material outside the coil wheel gradually decreases, the thickness of the base material outside the coil wheel gradually decreases. At this time, the extension plate sliding rod connected to the pressing material arc plate pulls the extension plate sliding rod to fit the base material through the tension spring, so that the base material outside the coil wheel is slowly released, and the base material passing through the guide roller is kept in a tensioned state, ensuring that the base material is in a tensioned state during the cutting by the cutting disk, avoiding the influence of the relaxation of the base material on the cutting smoothness and the incision flatness. At the same time, by the relative movement of the right moving frame and the left moving frame, the short connecting frame and the long connecting frame connected to the right moving frame are respectively driven to approach. At this time, the rotating shaft disk connected to the short connecting frame and the long connecting frame will clamp the convex strip shaft disk on the side of the coil wheel through the side keyway groove, and the coil wheel located above the pressing material arc plate can be lifted and fixed.

[0015] Adopting the above technical solution, the present invention can bring the following beneficial effects:

[0016] For the dust-free slitting and cutting machine used on the PCB cutting equipment, by setting the connecting rod fixed plate, vertical sliding rod, lifting frame, chute guide plate, right moving frame, left moving frame, connecting frame fixed seat, chuck end, transmission key rod, clamping position shaft disk, cutting disk, splicing chuck, linkage vertical rod, thin rod slider, and guiding cross bar, the interval between the upper chuck end and the lower chuck end is controlled to adjust the interval between the cutting disks to adjust the cutting thickness. Through the relative movement of the right moving frame and the left moving frame, the chuck end is driven to approach to clamp the splicing chuck on the side of the cutting disk, so that the splicing chuck can be quickly fixed and installed for quick replacement in case of wear later. While the hydraulic rod is used to push the lifting frame downward to control the mutual approach or separation of the chute guide plates to position the cutting disks, it also plays a driving role in the up and down movement of the right moving frame or the left moving frame connected to the chute guide plates, so as to adjust the distance between the upper chuck ends at different heights. By adjusting the interval, the pressure exerted by the cutting disks on the coil is further controlled to improve the cutting effect.

[0017] The dust-free slitting and cutting machine for PCB cutting equipment sets a hinge rod seat, a downward pressure hinge rod, a limit block, an inclined groove rod, a long hinge rod, a short hinge rod, a sliding rod block, a pressing plate, a short column, a deviation rectifying shaft rod, a deviation rectifying wheel, an electric heating tube, and a pressing wheel. By heating the pressing plate, the base material is kept flat, and the thermoplasticity of the material is increased by heating the base material, so that the cut of the base material is kept flat when it is pressed and cut by the cutting disc, and dust is avoided during the cutting process. At the same time, the deviation rectifying wheel connected by the deviation rectifying shaft rod centers the base material on the pallet, so that when the base material on the pallet enters the cutting area under the cutting disc, the cutting size can be guaranteed to be consistent, and the deviation of the base material can be avoided to affect the cutting effect.

[0018] The dust-free slitting and cutting machine for PCB cutting equipment sets a vertical guide rod, an elastic extension rod, a pressure connecting rod, a deflection groove frame, a pressing material arc plate, an extension plate sliding rod, an extended arc plate, a long connecting frame, a bracket plate, a short connecting frame, a rotating shaft disc, a wedge bar groove, a ribbed shaft disc, and a coiled material wheel. The extension plate sliding rod connected to the pressing material arc plate is pulled by a tension spring to make the extension plate sliding rod fit the base material, so that the base material outside the coiled material wheel is slowly released, and the base material passing through the guide roller is kept in a tensioned state, ensuring that the base material is in a tensioned state when the cutting disc cuts, avoiding the base material from being loose and affecting the cutting smoothness and the cut surface flatness. At the same time, the relative movement of the right shift frame and the left shift frame drives the relative movement of the short connecting frame and the long connecting frame to quickly fix the coiled material wheel by the rotating shaft disc, which is convenient for subsequent replacement.

[0019] The dust-free slitting and cutting machine for PCB cutting equipment sets a connecting block, a power-on end, an alarm end, a power-on wire, an elastic sheet, and a metal contact. When the cutting disc wears and becomes thinner, the elastic sheets on both sides are close to each other under the action of elastic force to make the metal contact conductive, so as to remind that the cutting disc is excessively worn and needs to be replaced.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1 - Figure 11, an embodiment of the present invention is: a dust-free slitting and cutting machine for a PCB cutting device, including a mounting plate 1, a top plate 2 is fixedly connected to the top surface of the mounting plate 1, a hydraulic rod 3 is fixedly connected to the top surface of the top plate 2, a lower pressing plate 4 is fixedly connected to the bottom end of the hydraulic rod 3, and a cutting mechanism 5 is arranged below the lower pressing plate 4;

[0034] The cutting mechanism 5 includes two connecting rod fixing plates 51, two vertical sliding rods 52 are fixedly connected to the bottom surface of the connecting rod fixing plates 51, a lifting frame 53 is slidably connected to the outer surface of the vertical sliding rods 52, sliding groove guide plates 54 are arranged on the front and rear sides of the lifting frame 53, a right moving frame 55 and a left moving frame 56 are respectively fixedly connected to the bottom surfaces of the two sliding groove guide plates 54, a plurality of connecting frame fixing seats 57 are fixedly connected to the sides of the left moving frame 56 and the right moving frame 55, one end of each connecting frame fixing seat 57 away from the right moving frame 55 or the left moving frame 56 is fixedly connected to a chuck end 58, a positioning shaft disc 510 is rotatably connected to the inner side of the chuck end 58, a splicing chuck 512 is fitted and connected to the side surface of the positioning shaft disc 510, a cutting disc 511 is fixedly connected to the edge surface of the splicing chuck 512, and a transmission key rod 59 is slidably connected to the side surface of the positioning shaft disc 510.

[0035] On the sides of the right moving frame 55 or the left moving frame 56, there is a linkage vertical rod 513 connected in a sliding manner. At the bottom end of the linkage vertical rod 513, there is a thin rod slider 514 fixedly connected. On the side of the thin rod slider 514, there is a guiding cross rod 515 connected in a sliding manner. Below the upper right moving frame 55 or the left moving frame 56, there are respectively arranged the lower right moving frame 55 or the left moving frame 56. The top surface of the lifting frame 53 is fixedly connected to the lower pressing plate 4. On the side of the chute guide plate 54, there is a chute, and the chute is composed of a slanting chute and a vertical chute connected. The chute guide plate 54 extends outwards with a convex column and is connected to the chute guide plate 54 in a sliding manner. The guiding cross rod 515 is fixedly connected to the mounting plate 1. The chuck ends 58 on the left and right sides of each cutting disc 511 are taken as a group. The lower right moving frame 55 is fixedly connected to the thin rod slider 514 on the same side, so that the splicing chuck 512 is spliced and fitted with the positioning shaft disc 510. Subsequently, control the hydraulic rod 3 to extend downwards, and push the lifting frame 53 connected to the lower pressing plate 4 to slide downwards along the vertical sliding rod 52. At this time, when the lifting frame 53 moves downwards, it pushes the chute on the side of the chute guide plate 54, so that the chute on the side of the chute guide plate 54 drives the right moving frame 55 and the left moving frame 56 to move under force. When the right moving frame 55 and the left moving frame 56 move, they drive the chuck end 58 through the connected connecting frame seat 57, so that the chuck ends 58 on both sides in the same group approach each other, and drive the positioning shaft discs 510 inside the two chuck ends 58 on both sides to clamp the splicing chuck 512 on the side of the cutting disc 511. When the chuck ends 58 connected to the right moving frame 55 and the left moving frame 56 approach each other, the transmission key rod 59 connected to the chuck end 58 slides with the positioning shaft disc 510. When driving the positioning shaft disc 510 on the side of one chuck end 58 to rotate through an external motor, the positioning shaft disc 510 on the side of this chuck end 58 drives the other positioning shaft disc 510 to rotate through the connected transmission key rod 59, and this positioning shaft disc 510 drives the positioning shaft disc 510 on the other side connected to it to rotate through fitting with the splicing chuck 512, so as to realize the synchronous rotation of multiple positioning shaft discs 510 driving the splicing chuck 512. As the hydraulic rod 3 is in a continuous extension state, the lifting frame 53 continues to move downwards, and the chute guide plate 54 connected to the lifting frame 53 moves from the inclined side chute to the connected vertical chute. At this time, the lifting frame 53 will push the chute guide plate 54 to be stressed vertically and move downwards. The downward movement of the chute guide plate 54 will drive the right moving frame 55 or the left moving frame 56 to move downwards along the connected linkage vertical rod 513, and make the upper right moving frame 55 or the left moving frame 56 approach the lower right moving frame 55 or the left moving frame 56. In this way, the interval between the upper chuck end 58 and the lower chuck end 58 can be controlled to adjust the interval between the cutting discs 511 to adjust the cutting thickness. Through the relative movement of the right moving frame 55 and the left moving frame 56 to drive the chuck end 58 to approach and clamp the splicing chuck 512 on the side of the cutting disc 511, the splicing chuck 512 can be quickly fixed and installed, so as to be quickly replaced in case of wear in the future. While controlling the chute guide plate 54 to approach or move away from each other to position the cutting disc 511 by pushing the lifting frame 53 to move downwards by the hydraulic rod 3, it also plays a driving role in the up and down movement of the right moving frame 55 or the left moving frame 56 connected to the chute guide plate 54.Thus, the distance between the chuck ends 58 at different heights is adjusted, and the cutting effect is improved by adjusting the interval to further control the pressure and shear of the cutting disc 511 on the coil material.

[0036] A detection module 8 is installed on the side of the cutting mechanism 5, a hot pressing mechanism 6 is arranged on the front side of the cutting mechanism 5, a tensioning mechanism 7 is arranged below the hot pressing mechanism 6, a support plate 9 is fixedly connected to the front side of the lower right moving frame 55, a guide roller 10 is rotatably connected to the bottom end of the support plate 9, and a base material 11 is arranged above the support plate 9.

[0037] The detection module 8 includes two connecting blocks 81. The two connecting blocks 81 are respectively fixedly connected to the front sides of the two chuck ends 58 in the same group. One ends of the two connecting blocks 81 away from the chuck ends 58 are respectively fixedly connected with a power-on end 82 and an alarm end 83. The sides of the power-on end 82 and the alarm end 83 are electrically connected with a power-on wire 84. Elastic sheets 85 are fixedly connected to the rear sides of the power-on end 82 and the alarm end 83. Metal contact pieces 86 are fixedly connected to the top surfaces of the elastic sheets 85. When the two chuck ends 58 approach each other, the connecting blocks 81 connected to the two chuck ends 58 in the same group drive the power-on end 82 and the alarm end 83 to approach each other. The elastic sheets 85 connected to the power-on end 82 and the alarm end 83 move together with them and fit against the side surface of the cutting disc 511. When the cutting disc 511 wears and becomes thinner during use, the elastic sheets 85 attached to both sides of the cutting disc 511 will approach each other under the action of elasticity until the metal contact pieces 86 connected to the elastic sheets 85 approach and contact. At this time, the metal contact piece 86 is in a conductive state with the buzzer built in the alarm end 83 through the elastic sheet 85. At this time, the buzzer built in the alarm end 83 works. When the cutting disc 511 wears and becomes thinner, the elastic sheets 85 sandwiched on both sides approach each other under the action of elastic force to make the metal contact piece 86 conductive, so as to remind that the cutting disc 511 is excessively worn and needs to be replaced.

A pressing wheel 613 is rotatably connected to the bottom end of the lower pressing hinge rod 62. A return spring is arranged on the outer side of the inclined groove rod 64, and both ends of the return spring are fixedly connected to the sliding rod block 67 and the lower pressing hinge rod 62 respectively. A torsion spring is arranged on the outer side of the short column 69, and both ends of the torsion spring are fixedly connected to the short column 69 and the deviation correcting shaft rod 610 respectively. There is damping between the lower pressing hinge rod 62 and the hinge rod seat 61. The hinge rod seat 61 connected to the right moving frame 55 drives the lower pressing hinge rod 62 to approach the support plate 9. When the pressing plate 68 on the side surface of the lower pressing hinge rod 62 fits the base material 11 on the support plate 9, at this time, the pressing plate 68 drives the sliding rod block 67 to slide along the short hinge rod 66 and stretch the return spring through the force received by the connected extension plate sliding rod 76. At this time, the electric heating tube 612 on the pressing plate 68 transfers heat to the pressing plate 68 through heating, and then contacts the base material 11 through the pressing plate 68 to heat the base material 11. By heating the pressing plate 68, the base material 11 is kept flat, and the thermoplasticity of the material is increased by heating the base material 11, so that the cut of the base material 11 is kept flat when being pressed and cut by the cutting disc 511, and dust generation during the cutting process is avoided by pressing and cutting. When the base material 11 passes through the bottom surface of the pressing plate 68, the deviation correcting wheels 611 at both ends of the pressing plate 68 will guide the movement of the base material 11. When the base material 11 deviates towards one of the deviation correcting wheels 611, the deviation correcting wheel 611 will drive the deviation correcting shaft rod 610 to deflect a small angle around the short column 69 and twist the torsion spring. At this time, the deflected deviation correcting wheel 611 will deviate towards the side close to the right moving frame 55, and the deviation correcting wheel 611 connected to the deviation correcting shaft rod 610 is used to guide the base material 11 to rotate away from the contacted deviation correcting wheel 611 along with the pressing wheel 613, so that the base material 11 is centered above the support plate 9. By using the deviation correcting wheel 611 connected to the deviation correcting shaft rod 610 to center the base material 11 on the support plate 9, it can ensure that the cutting size is consistent when the base material 11 on the support plate 9 enters under the cutting disc 511 for cutting, and avoid the cutting effect caused by the deviation movement of the base material 11.

[0039] The tensioning mechanism 7 includes a vertical guide rod 71. The bottom end of the vertical guide rod 71 is slidably connected with an elastic extension rod 72. The bottom end of the elastic extension rod 72 is fixedly connected with a pressure-applying connecting rod 73. The outer surface of the pressure-applying connecting rod 73 is slidably connected with a deflection groove frame 74. The bottom end of the deflection groove frame 74 is hinged with a pressure-applying arc plate 75. The front side of the pressure-applying arc plate 75 is fixedly connected with an extension plate sliding rod 76. The outer surface of the extension plate sliding rod 76 is slidably connected with an extension arc plate 77. The bottom surface of the lower left moving frame 56 is fixedly connected with a long connecting frame 78. The bottom surface of the lower right moving frame 55 is fixedly connected with a short connecting frame 710. The bottom surfaces of both the short connecting frame 710 and the long connecting frame 78 are fixedly connected with a bracket plate 79. The bottom ends of both the short connecting frame 710 and the long connecting frame 78 are rotatably connected with a rotating shaft disc 711. A keyway groove 712 is formed on the side surface of the rotating shaft disc 711. A coiling material wheel 714 is arranged between the two rotating shaft discs 711. Both ends of the coiling material wheel 714 are fixedly connected with a ribbed shaft disc 713. The vertical guide rod 71 is fixedly connected with the bottom surface of the lifting frame 53. An internal spring is arranged inside the elastic extension rod 72, and both ends of the internal spring are respectively fixedly connected with the vertical guide rod 71 and the elastic extension rod 72. A sliding rotating shaft is fixedly connected to the side surface of the deflection groove frame 74, and the sliding rotating shaft is slidably connected with the bracket plate 79. A tension spring is arranged outside the extension plate sliding rod 76, and both ends of the tension spring are respectively connected with the extension arc plate 77 and the pressure-applying arc plate 75. The rotating shaft disc 711 and the ribbed shaft disc 713 are structurally engaged through the keyway groove 712. The lifting frame 53 will drive the connected vertical guide rod 71 and elastic extension rod 72 to move downward together. Due to the large rigidity of the internal spring of the elastic extension rod 72, when the vertical guide rod 71 is stressed, it will push the elastic extension rod 72 to move downward through the internal spring, and the pressure-applying connecting rod 73 connected to the elastic extension rod 72 will push the deflection groove frame 74. At this time, the deflection groove frame 74 will deflect around the connection of the bracket plate 79. At this time, the deflection groove frame 74 will lift the pressure-applying arc plate 75 upward, so that the pressure-applying arc plate 75 and the extension arc plate 77 will jointly fit the base material 11 outside the coiling material wheel 714. As the base material 11 outside the coiling material wheel 714 gradually decreases, the thickness of the base material 11 outside the coiling material wheel 714 gradually decreases. At this time, the extension plate sliding rod 76 connected to the pressure-applying arc plate 75 pulls the extension plate sliding rod 76 through the tension spring to fit the base material 11, so that the base material 11 outside the coiling material wheel 714 is slowly released, and the base material 11 passing through the guide roller 10 is kept in a tensioned state, ensuring that the base material 11 is in a tensioned state when the cutting disc 511 cuts, avoiding the relaxation of the base material 11 from affecting the cutting smoothness and the incision flatness. At the same time, by using the relative movement of the right moving frame 55 and the left moving frame 56, the short connecting frame 710 connected to the right moving frame 55 and the long connecting frame 78 are respectively driven to approach. At this time, the rotating shaft disc 711 connected to the short connecting frame 710 and the long connecting frame 78 will clamp the ribbed shaft disc 713 on the side surface of the coiling material wheel 714 through the keyway groove 712 on the side surface, and then the coiling material wheel 714 located above the pressure-applying arc plate 75 can be lifted and fixed for replacing the coiling material wheel 714.The relative movement of the right shifting frame 55 and the left shifting frame 56 drives the relative movement of the short connecting frame 710 and the long connecting frame 78, enabling the rotating shaft disc 711 to quickly fix the coil wheel 714, which facilitates subsequent replacement.

[0040] Working principle: In a stacked manner, multiple layers of PCB materials are stacked, and each layer of material is bonded with glue. Under the action of a pressing device, they are pressed together so that the excess glue between the materials overflows from the side. The overflowing glue is roughly cut by a downward pressing guillotine. After simultaneously cutting both sides of the square PCB material, the material is rotated 90 degrees to continue cutting the other two sides. Subsequently, it is moved by a conveyor belt to the lower part of another device, where a special blade is used to perform a detailed cutting process on the edge of the material, such as chamfering. During the process, the internal coordinate points of the PCB board are viewed through an x-ray camera, and the material is cut to the appropriate size according to the coordinate points. After the process is completed, the material is conveyed to a deburring device to remove the excess burrs. After deburring, the overall thickness of the board is measured by laser ranging to determine whether the cut material is qualified.

[0041] As a processing device before PCB stacking and bonding, this device cuts the PCB sheet coil into strips. When installing the cutting disc 511, align the splicing chuck 512 on the side of the cutting disc 511 with the positioning shaft disc 510 on one side of the chuck end 58, and make the splicing chuck 512 fit with the positioning shaft disc 510. Then control the hydraulic rod 3 to extend downward, and push the lifting frame 53 connected to the lower pressing plate 4 to slide downward along the vertical sliding rod 52. At this time, the lifting frame 53 moves downward to push the chute on the side of the chute guide plate 54, so that the chute on the side of the chute guide plate 54 drives the right moving frame 55 and the left moving frame 56 to move under force. When the right moving frame 55 and the left moving frame 56 move, they drive the chuck end 58 to move through the connected connecting frame base 57, making the two chuck ends 58 on both sides in the same group approach each other, and driving the positioning shaft discs 510 inside the two chuck ends 58 on both sides to clamp the splicing chuck 512 on the side of the cutting disc 511. When the chuck ends 58 connected to the right moving frame 55 and the left moving frame 56 approach each other, the transmission key rod 59 connected to the chuck end 58 slides with the positioning shaft disc 510. When an external motor drives the positioning shaft disc 510 on the side of one chuck end 58 to rotate, the positioning shaft disc 510 on the side of this chuck end 58 drives another positioning shaft disc 510 to rotate through the connected transmission key rod 59, and this positioning shaft disc 510 drives the positioning shaft disc 510 on the other side at the connected part to rotate through fitting with the splicing chuck 512, so as to realize the synchronous rotation of multiple positioning shaft discs 510 driving the splicing chuck 512. As the hydraulic rod 3 is in a continuous extension state, the lifting frame 53 continues to move downward, and the chute guide plate 54 connected to the lifting frame 53 moves from the inclined side groove to the connected vertical groove. At this time, the lifting frame 53 will push the chute guide plate 54 to move downward under vertical force. The downward movement of the chute guide plate 54 will drive the right moving frame 55 or the left moving frame 56 to move downward along the connected linkage vertical rod 513, and make the upper right moving frame 55 or the left moving frame 56 approach the lower right moving frame 55 or the left moving frame 56, so as to control the interval between the upper chuck end 58 and the lower chuck end 58, and adjust the interval between the cutting discs 511 to adjust the cutting thickness. Through the relative movement of the right moving frame 55 and the left moving frame 56 to drive the chuck end 58 to approach and clamp the splicing chuck 512 on the side of the cutting disc 511, the splicing chuck 512 can be quickly fixed and installed, so as to be quickly replaced in case of wear in the future. While the hydraulic rod 3 pushes the lifting frame 53 to move downward to control the chute guide plate 54 to approach or move away from each other to position the cutting disc 511, it also drives the upward and downward movement of the right moving frame 55 or the left moving frame 56 connected to the chute guide plate 54, so as to adjust the distance between the chuck ends 58 at different heights above. By adjusting the interval, further control the pressure and shear of the cutting disc 511 on the coil to improve the cutting effect;

[0042] When the cutting disc 511 is placed between the chuck ends 58, as the two chuck ends 58 on both sides approach each other, the connecting blocks 81 connected to the two chuck ends 58 of the same group drive the power-on end 82 and the alarm end 83 to approach each other respectively. The elastic sheet 85 connected to the power-on end 82 and the alarm end 83 moves with them and fits against the side of the cutting disc 511. When the cutting disc 511 wears and thins during use, the elastic sheets 85 on both sides of the cutting disc 511 will approach each other under the elastic action. Until the metal contacts 86 connected to the elastic sheet 85 approach and contact each other, at this time, the metal contacts 86 are in a conductive state with the buzzer built in the alarm end 83 through the elastic sheet 85. At this time, the buzzer built in the alarm end 83 works. When the cutting disc 511 wears and thins, the elastic sheets 85 on both sides are close to each other under the elastic force to make the metal contacts 86 conductive, to remind that the cutting disc 511 is excessively worn and needs to be replaced;

[0043] When the upper right moving frame 55 moves downward, the hinge rod seat 61 connected to the right moving frame 55 drives the downward pressing hinge rod 62 to approach the pallet 9. When the pressing plate 68 on the side of the downward pressing hinge rod 62 fits against the base material 11 on the pallet 9, at this time, the pressing plate 68 pushes the slide block 67 to slide along the short hinge rod 66 and stretch the return spring through the extended plate slide rod 76 connected to it. At this time, the electric heating tube 612 on the pressing plate 68 transfers heat to the pressing plate 68 through heating, and then transfers the heat to the base material 11 through the contact between the pressing plate 68 and the base material 11 to heat the base material 11. By heating the base material 11 by the pressing plate 68, the base material 11 is kept flat, and the thermoplasticity of the material is increased by heating the base material 11, so that the cut of the base material 11 when being pressed and cut by the cutting disc 511 remains flat, and dust generation during the cutting process is avoided by pressing and cutting. When the base material 11 passes under the bottom surface of the pressing plate 68, the alignment wheels 611 at both ends of the pressing plate 68 will guide the movement of the base material 11. When the base material 11 deviates from one of the alignment wheels 611, the alignment wheel 611 will drive the alignment shaft rod 610 to deflect a small angle around the short column 69 and twist the torsion spring under force. At this time, the deflected alignment wheel 611 will deflect towards the side close to the right moving frame 55. By using the offset of the alignment wheel 611 to guide the base material 11 to rotate away from the contacted alignment wheel 611 along with the pressing wheel 613, the base material 11 is centered above the pallet 9. By using the alignment wheel 611 connected to the alignment shaft rod 610, the base material 11 is centered on the pallet 9, which can ensure the consistency of the cutting size when the base material 11 on the pallet 9 enters under the cutting disc 511 for cutting, and avoid the offset movement of the base material 11 during cutting;

[0044] When the lifting frame 53 moves downward, the lifting frame 53 will drive the connected vertical guide rod 71 and the elastic extension rod 72 to move downward together. Since the built-in spring of the elastic extension rod 72 has a large rigidity, when the vertical guide rod 71 is stressed, it will push the elastic extension rod 72 to move downward through the built-in spring, and the pressure link 73 connected to the elastic extension rod 72 will push the deflection groove frame 74. At this time, the deflection groove frame 74 will deflect around the connection of the bracket plate 79. At this time, the deflection groove frame 74 will lift the pressing material arc plate 75 upward, so that the pressing material arc plate 75 and the extension arc plate 77 will fit the base material 11 outside the coil wheel 714 together. As the base material 11 outside the coil wheel 714 gradually decreases, the thickness of the base material 11 outside the coil wheel 714 gradually decreases. At this time, the extension plate slide rod 76 connected to the pressing material arc plate 75 pulls the extension plate slide rod 76 to fit the base material 11 through the tension spring, so that the base material 11 outside the coil wheel 714 is slowly released, and the base material 11 passing through the guide roller 10 is kept in a tensioned state, ensuring that the base material 11 is in a tensioned state during the cutting of the cutting disc 511, avoiding the slack of the base material 11 from affecting the cutting smoothness and the incision flatness. At the same time, by using the relative movement of the right shift frame 55 and the left shift frame 56, the short connection frame 710 connected to the right shift frame 55 and the long connection frame 78 are respectively driven to approach. At this time, the rotating shaft disc 711 connected to the short connection frame 710 and the long connection frame 78 will clamp the convex bar shaft disc 713 on the side of the coil wheel 714 through the side wedge groove 712, and the coil wheel 714 located above the pressing material arc plate 75 can be lifted and fixed, so as to replace the coil wheel 714. By using the relative movement of the right shift frame 55 and the left shift frame 56 to drive the relative movement of the short connection frame 710 and the long connection frame 78, the rotating shaft disc 711 can quickly fix the coil wheel 714, which is convenient for subsequent replacement.
