Although traditional PCB cutting and grinding equipment meets the basic needs of PCB processing to a certain extent, with the increasing complexity of PCB design and the improvement of market requirements for high-efficiency and precise production, the deficiencies of traditional equipment are gradually exposed. The modern PCB industry is developing in the direction of higher precision, higher speed, and more intelligence to address these issues.

[0003] The patent with publication number CN111113520A discloses a cutting and grinding integrated machine for PCB processing, including a mounting frame and a workbench. The mounting frame is installed on the outer wall of the upper end of the workbench, and a limit collection device is arranged at the upper end of the mounting frame. The cutting and grinding integrated machine for PCB processing of the present invention mainly consists of structures such as a cutting wheel, a limit collection device, a mounting frame, a grinding disc, a rotating base, a connecting rod, a motor, a fixed table, a pressing plate, a support rod, a fixing block, and a tightening nut.

However, this patent still has problems such as low grinding efficiency during automatic single-sided grinding and the grinding effect being affected by the lack of force on the grinding area. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a cutting and grinding integrated machine for PCB processing, which solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A cutting and grinding integrated machine for PCB processing, including a processing table, the top surface of the processing table is fixedly connected with a housing, a hydraulic cylinder is installed at the top end of the housing, a pressing plate is arranged inside the housing, a lifting structure is arranged below the pressing plate, an orientation adjusting mechanism is arranged below the lifting structure, and a cutting and grinding mechanism is arranged on the side of the orientation adjusting mechanism;

[0006] The cutting and grinding mechanism includes a protective shell, the inner wall of the protective shell is fixedly connected with a limiting bracket, a cutting disc is rotatably connected inside the limiting bracket, a transmission belt is arranged on one side of the cutting disc close to the orientation mechanism, a grinding disc is arranged at the rear end of the transmission belt, two hinge seats are fixedly connected to the rear end of the limiting bracket, two touch pressure hinge rods are hinged to the side of each hinge seat, the bottom end of each touch pressure hinge rod is rotatably connected with a rotating shaft, a turning rod is fixedly connected to the top end of one of the touch pressure hinge rods, and the top end of the turning rod is slidably connected with a vertical groove shaft disc.

[0007] According to the above technical solution, a sliding piece shaft is rotatably connected to the vertical groove shaft disc close to the grinding disc, a cross key rod is fixedly connected to one end of the sliding piece shaft away from the vertical groove shaft disc, a positioning shaft is slidably connected to one end of the cross key rod away from the sliding piece shaft, rotating shaft pieces are rotatably connected to the outer sides of the positioning shaft and the sliding piece shaft, the cutting disc includes a cutter disc, six cutter corners are fixedly connected to the edge side of the cutter disc, saw grooves are formed at the ends of each cutter corner, and a cutting piece is fixedly connected to one side of the cutter corner away from the cutter disc.

[0008] According to the above technical solution, a grinding disc is fixedly connected to the ends of the cross key rod and the positioning shaft, the rotating shaft piece is fixedly connected to the protective shell. When cutting the PCB board, the lifting structure moves downward to drive the orientation mechanism to descend, so that the cutting and grinding mechanism connected to the orientation mechanism approaches the surface of the PCB board through the limiting bracket. The cutting disc will sink into the surface of the PCB board and make the limiting bracket fit the surface of the cutting area. The thickness of the cutting by the cutting disc is restricted by the limiting bracket to prevent the cutting disc from damaging the processing table. While the cutting disc operates for cutting, the cutting disc drives the pulley on the side of the grinding disc to rotate through the transmission belt. At the same time, after the rotating shafts at both sides of the limiting bracket fit the board, the touch pressure hinge rods connected by the rotating shafts deflect around the connection points of the hinge seats. After one of the touch pressure hinge rods deflects, it will drive the turning rod to deflect together. The deflected turning rod will drive the vertical groove shaft disc to move away from the protective shell, and the vertical groove shaft disc will pull the sliding piece shaft to slide with the rotating shaft piece connected to the outside, so that the grinding disc connected to the sliding piece shaft moves away from the grinding disc connected to the positioning shaft, and the positioning shaft slides relatively away from the cross key rod. At this time, the rotation of the positioning shaft drives the sliding piece shaft to rotate through the connected cross key rod, so that the sliding piece shaft rotates relative to the vertical groove shaft disc, and the grinding disc connected to the positioning shaft fits one side of the cutting groove of the board for grinding.

[0009] According to the above technical solution, the lifting structure includes a lifting frame, the lifting frame is fixedly connected to the bottom end of the pressing plate, a transverse moving frame is slidably connected inside the lifting frame, rotating shaft seats are fixedly connected to both ends of the transverse moving frame, a driving screw is rotatably connected to the top side of the rotating shaft seat, a driving end is rotatably connected to the outer surface of the driving screw, and a mounting plate is fixedly connected to the bottom surface of the driving end.

[0010] According to the above technical solution, the direction adjusting mechanism includes a steering shaft seat, a torsion block is slidably connected to the inner side of the steering shaft seat, a central fixing rod is slidably connected to the center of the torsion block, a clamping strip is fixedly connected to the outer edge of the torsion block, two guiding cutting surfaces are opened on the bottom surface of the steering shaft seat, a linkage block is fixedly connected to the outer side of the torsion block, an inclined guiding block is fixedly connected to the side of the linkage block away from the torsion block, a deflection pushing block is fixedly connected to the side of the inclined guiding block away from the linkage block, a driving seat plate is fixedly connected to the bottom end of the clamping strip, and a cutting motor is fixedly connected to the bottom surface of the driving seat plate.

[0011] According to the above technical solution, the steering shaft seat is fixedly connected to the bottom surface of the mounting plate. A torsion spring is arranged on the outer side of the central fixing rod, and two ends of the torsion spring are respectively fixedly connected to the torsion block and the mounting plate. The cutting motor is fixedly connected to the protective shell. When the cutting direction of the cutting blade needs to be adjusted, the external motor is driven by the control module built in the driving end to drive the driving screw rod to rotate, so that the driving end moves to align with the touch-pressure folding rod installed on the front side of the lifting frame. Then, the transverse moving frame is controlled to move forward by the driving wheel built in the rotating shaft seat. When the touch-pressure folding rod contacts the inclined guiding block, as the transverse moving frame continues to move, the touch-pressure folding rod presses the inclined guiding block. After being pressed, the inclined guiding block drives the connected linkage block to make the torsion block slide down along the central fixing rod and pull the torsion spring to stretch. When the clamping strip connected to the side of the torsion block is no longer restricted by the touch-pressure folding rod, the transverse moving frame continues to move to drive the steering shaft seat to continuously approach the touch-pressure folding rod. At this time, the touch-pressure folding rod presses the top end of the inclined guiding block, and pushes the inclined guiding block to rotate around the torsion block through the connected linkage block and the torsion block. As the touch-pressure folding rod pushes the top end of the inclined guiding block, the contact position between the touch-pressure folding rod and the inclined guiding block moves to the deflection pushing block. At this time, the stretched torsion spring has a tendency to contract. The connected torsion block is driven by the contraction of the torsion spring to slide along the guiding cutting surface opened on the touch-pressure folding rod until the clamping strip connected to the torsion block is engaged with the touch-pressure folding rod again. When the driving seat plate connected to the clamping strip needs to be reset, the external motor is driven by the control module built in the driving end to drive the driving screw rod, so that the driving end moves to the position of the touch-pressure folding rod behind the lifting frame, and the driving end approaches the touch-pressure folding rod here. At this time, the touch-pressure folding rod contacts the inclined guiding block and presses it, so that the inclined guiding block drives the torsion block to move down through the linkage block, and the clamping strip connected to the torsion block is separated from the touch-pressure folding rod. At this time, the torsion block will be reset under the torsional action of the torsion spring. The reset torsion block will rotate around the central fixing rod, and the torsion block is deflected after being separated from the engaged state by the touch-pressure folding rod pressing the inclined guiding block.

[0012] According to the above technical solution, the positioning mechanism includes an elastic vertical frame, a lower pressure plate is slidably connected to the outside of the elastic vertical frame, a vertical guide plate is slidably connected to the top surface of the lower pressure plate, the front and rear ends of the vertical guide plate are slidably connected with inclined groove sliders, the bottom ends of the two inclined groove sliders are fixedly connected with a positioning cross bar, the bottom surface of the positioning cross bar is slidably connected with a track, the middle side of the positioning cross bar is slidably connected with a positioning block, one end of the positioning block away from the positioning cross bar is fixedly connected with a rubber block, deflection teeth are engaged on both the front and rear sides of the positioning block, the bottom surface of the deflection teeth is fixedly connected with a deflection rod, and a clamping groove rod is fixedly connected to the side surface of the deflection rod.

[0013] According to the above technical solution, the vertical guide plate slides through the top surface of the lower pressure plate to the bottom surface, the vertical guide plate is fixedly connected to the top surface of the processing table, the track is fixedly connected to the top surface of the processing table, a plurality of clamping grooves are provided on the side surface of the clamping groove rod, a pressing spring is arranged inside the positioning block, and the two ends of the pressing spring are respectively connected to the positioning block and the positioning cross bar. When the hydraulic cylinder extends downward to push the pressing plate to be pressed, the pressing plate drives the transverse moving frame to move downward and pushes the lower pressure plate to descend. The lower pressure plate pushes the lower pressure plate to move vertically along the vertical guide plate through the return spring, so that the vertical guide plate slides along the side surface of the inclined groove slider, and the vertical guide plate extends into the inclined groove inside the side surface of the inclined groove slider and presses the inclined groove inside the inclined groove slider. The stressed inclined groove slider drives the connected positioning cross bar to slide along the track and approach the plate. As the positioning cross bar and the positioning block move together, when the positioning block contacts the plate through the rubber block, the rubber block is pushed by the reaction force of the plate to relatively slide the positioning block and the positioning cross bar and compress the pressing spring. Subsequently, the movement of the positioning block drives the engaged deflection teeth to move. At this time, the deflection teeth will drive the connected deflection rod to deflect, and the clamping groove rod will be clamped through the deflection rod.

[0014] The present invention provides a cutting and grinding integrated machine for PCB processing. It has the following beneficial effects:

[0015] In the present invention, by providing a protective shell, a limiting bracket, a cutting blade, a rotating shaft blade, a positioning shaft, a cross key rod, a hinge seat, a touch pressure hinge rod, a flipping rod, a vertical groove shaft disc, a sliding blade shaft, a grinding disc, and a transmission belt, the grinding disc connected by the positioning shaft fits one side of the cutting groove of the plate for grinding, and the grinding disc connected by the sliding blade shaft is far away from the positioning shaft to grind the burrs on the side of the other cutting groove, so as to realize the simultaneous grinding of both sides of the cutting groove of the plate, improve the flatness of the cutting opening, and at the same time, grinding both sides of the cut at the same time keeps the flatness of the deburring of the cut consistent, further improving the cutting and grinding efficiency at the same time and avoiding secondary grinding. In addition, by the mutual separation of the two grinding discs to apply force to the contact surface, the grinding effect on the side of the narrow cutting groove is improved;

[0016] In the present invention, by providing a touch-pressure folding rod, a steering shaft seat, a torsion block, a clamping strip, a guiding cutting surface, a central fixing rod, a linkage block, an inclined guiding block, a deflection pushing block, a driving seat plate, and a cutting motor, when the touch-pressure folding rod touches the inclined guiding block, the torsion block is disengaged from the engaged state and deflected. By adjusting the deflection, the driving seat plate connected to the cutting motor can adjust the cutting direction of the cutting blade. The adjustment direction mechanism is combined with the lifting structure to achieve automatic direction adjustment. By changing the cutting orientation of the cutting blade, the adjustment of the sheet direction is avoided, and the steps of repositioning the cutting position after the sheet adjustment are simplified. By visually compensating the cutting position of the cutting blade, precise and rapid cutting can be achieved after adjusting the cutting orientation of the cutting blade;

[0017] In the present invention, by providing an elastic vertical frame, a lower pressing plate, a vertical guiding plate, an inclined groove sliding plate, a track, a positioning cross bar, a positioning block, a rubber block, a deflection gear, a deflection rod, and a clamping groove rod, the movement of the positioning block drives the movement of the engaged deflection gear. At this time, the deflection gear drives the connected deflection rod to deflect, and the clamping groove rod is clamped by the deflection rod. The clamping groove at different positions on the clamping groove rod can be used to position PCB sheets of different sizes. In addition, by using the clamping groove rod to position the four corners of the sheet, the shielding and cooperation restrictions on the sheet positioning can be avoided to the greatest extent, and the pressure of the supporting bracket is applied to prevent the sheet from shifting during the cutting process. In addition, during the swinging of the clamping groove rod with the deflection rod, the generated debris can be pushed into the collection hole on the processing table for collection to play a role in cleaning the debris.

A sliding piece shaft 511 is rotatably connected to the vertical groove shaft disc 510 close to the grinding disc 512. A cross key rod 56 is fixedly connected to the end of the sliding piece shaft 511 away from the vertical groove shaft disc 510. The end of the cross key rod 56 away from the sliding piece shaft 511 is slidably connected to a positioning shaft 55. Rotating shaft pieces 54 are rotatably connected to the outer sides of the positioning shaft 55 and the sliding piece shaft 511. Grinding discs 512 are fixedly connected to the ends of the cross key rod 56 and the positioning shaft 55. The rotating shaft piece 54 is fixedly connected to the protective shell 51.The cutting disc 53 includes a cutter head 531. Six cutter corners 532 are fixedly connected to the edge side of the cutter head 531. A saw groove 533 is formed at the end of each cutter corner 532. A cutting piece 534 is fixedly connected to the side of the cutter corner 532 away from the cutter head 531. A circular turntable is rotatably connected to the center of the bottom surface of the processing table 1. The circular turntable is embedded with a plurality of suction cups distributed in an annular array from the surface to the inside. And an external motor is fixedly connected to the axis of the circular turntable. The suction cups are used to adsorb the board. At the same time, the circular turntable is used to adjust the orientation of the board. The cutting and grinding mechanism 5 connected to the orientation adjustment mechanism 6 approaches the surface of the PCB board through the limiting bracket 52. The cutting disc 53 will sink into the surface of the PCB board and make the limiting bracket 52 fit the surface of the cutting area. The thickness of the cutting by the cutting disc 53 is limited by the limiting bracket 52 to prevent the cutting disc 53 from damaging the processing table 1. While the cutting disc 53 operates for cutting, the cutting disc 53 drives the pulley on the side of the grinding disc 512 to rotate through the transmission belt 513. At the same time, after the rotating shafts on both sides of the limiting bracket 52 fit the board, the touch pressure hinge rods 58 connected by the rotating shafts deflect around the connection point of the hinge seat 57. After one of the touch pressure hinge rods 58 deflects, it will drive the flipping rod 59 to deflect together. The deflected flipping rod 59 will drive the vertical groove shaft disc 510 to move away from the protective shell 51, and make the vertical groove shaft disc 510 pull the sliding piece shaft 511 to slide with the rotating shaft piece 54 connected to the outside, so that the grinding disc 512 connected to the sliding piece shaft 511 moves away from the grinding disc 512 connected to the positioning shaft 55.

The grinding disc 512 connected to the positioning shaft 55 fits one side of the cutting groove of the board for grinding, and the grinding disc 512 connected to the sliding piece shaft 511 moves away from the positioning shaft 55 to grind the burrs on the side of the other cutting groove, so as to realize the simultaneous grinding of both sides of the cutting groove of the board, improve the flatness of the cutting area, and at the same time grind both sides of the cut at the same time to keep the flatness of the deburred cut consistent, further improve the cutting and grinding efficiency at the same time, avoid secondary grinding. In addition, by applying force to the contact surface by the mutual separation of the two grinding discs 512, the grinding effect on the side of the narrow cutting groove is improved.,

[0032] The lifting structure 9 includes a lifting frame 91, which is fixedly connected to the bottom end of the pressing plate 3. A transverse moving frame 92 is slidably connected inside the lifting frame 91. Both ends of the transverse moving frame 92 are fixedly connected with a rotating shaft seat 93. The top side of the rotating shaft seat 93 is rotatably connected with a driving screw rod 94. The outer surface of the driving screw rod 94 is rotatably connected with a driving end 95. The bottom surface of the driving end 95 is fixedly connected with a mounting plate 96. The steering mechanism 6 includes a steering shaft seat 62. A torsion block 63 is slidably connected inside the steering shaft seat 62. A central fixed rod 66 is slidably connected at the center of the torsion block 63. A clamping strip 64 is fixedly connected to the outer edge of the torsion block 63. Two guiding cut surfaces 65 are opened on the bottom surface of the steering shaft seat 62. A linkage block 67 is fixedly connected to the outside of the torsion block 63. An inclined guiding block 68 is fixedly connected to the side of the linkage block 67 away from the torsion block 63. A deflection pushing block 69 is fixedly connected to the side of the inclined guiding block 68 away from the linkage block 67. The bottom end of the clamping strip 64 is fixedly connected with a driving seat plate 610. A cutting motor 611 is fixedly connected to the bottom surface of the driving seat plate 610. The steering shaft seat 62 is fixedly connected to the bottom surface of the mounting plate 96. A torsion spring is arranged outside the central fixed rod 66, and the two ends of the torsion spring are respectively fixedly connected with the torsion block 63 and the mounting plate 96. The cutting motor 611 is fixedly connected to the protective shell 51. After the driving end 95 moves to align with the touch-pressure folding rod 61 installed on the front side of the lifting frame 91, the transverse moving frame 92 is controlled to move forward through the driving wheel built in the rotating shaft seat 93. When the touch-pressure folding rod 61 contacts the inclined guiding block 68, as the transverse moving frame 92 continues to move, the touch-pressure folding rod 61 presses the inclined guiding block 68. After being pressed, the inclined guiding block 68 drives the connected linkage block 67 to make the torsion block 63 slide down along the central fixed rod 66 and pull the torsion spring to stretch. When the clamping strip 64 connected to the side of the torsion block 63 is no longer restricted by the touch-pressure folding rod 61, the transverse moving frame 92 continues to move and drives the steering shaft seat 62 to continuously approach the touch-pressure folding rod 61. At this time, the touch-pressure folding rod 61 presses the top of the inclined guiding block 68, pushing the inclined guiding block 68 to rotate around the torsion block 63 through the connected linkage block 67 and the torsion block 63. As the touch-pressure folding rod 61 pushes the top of the inclined guiding block 68, the contact position between the touch-pressure folding rod 61 and the inclined guiding block 68 moves to the deflection pushing block 69. At this time, the stretched torsion spring has a tendency to contract. The connected torsion block 63 is driven to slide along the guiding cut surface 65 opened on the touch-pressure folding rod 61 through the contraction of the torsion spring until the clamping strip 64 connected to the torsion block 63 is engaged with the touch-pressure folding rod 61 again. When the driving seat plate 610 connected to the clamping strip 64 needs to be reset, the external motor is driven by the control module built in the driving end 95 to drive the driving screw rod 94, so that the driving end 95 moves to the position of the touch-pressure folding rod 61 behind the lifting frame 91, making the driving end 95 approach the touch-pressure folding rod 61 here. At this time, the touch-pressure folding rod 61 contacts the inclined guiding block 68 and applies pressure, making the inclined guiding block 68 drive the torsion block 63 to move down through the linkage block 67, so that the clamping strip 64 connected to the torsion block 63 disengages from the touch-pressure folding rod 61. At this time, the torsion block 63 will be reset under the torsional action of the torsion spring.When the torsion block 63 is reset, it rotates around the central fixed rod 66. By pressing the folding rod 61 to press the inclined guide block 68, the torsion block 63 is deflected after being disengaged from the engaged state. By adjusting the deflection, the cutting direction of the cutting blade 53 connected to the driving seat plate 610 by the cutting motor 611 can be adjusted. The adjustment direction mechanism is combined with the lifting structure 9 to realize automatic direction adjustment. By changing the cutting orientation of the cutting blade 53, the adjustment of the plate direction is avoided, and the steps of repositioning the cutting position after the plate adjustment are simplified. By visually compensating the cutting position of the cutting blade 53, precise and rapid cutting can be achieved after adjusting the cutting orientation of the cutting blade 53.,

[0033] The positioning mechanism 7 includes an elastic vertical frame 71. A lower pressing plate 72 is slidably connected to the outer side of the elastic vertical frame 71. A vertical guide plate 73 is slidably connected to the top surface of the lower pressing plate 72. The front and rear ends of the vertical guide plate 73 are slidably connected to inclined groove sliding plates 74. The bottom ends of the two inclined groove sliding plates 74 are fixedly connected to a positioning cross bar 76. A track 75 is slidably connected to the bottom surface of the positioning cross bar 76. A positioning block 77 is slidably connected to the middle side surface of the positioning cross bar 76. One end of the positioning block 77 away from the positioning cross bar 76 is fixedly connected to a rubber block 78. Deflection teeth 79 are engaged on both the front and rear sides of the positioning block 77. A deflection rod 710 is fixedly connected to the bottom surface of the deflection tooth 79. A clamping groove rod 711 is fixedly connected to the side surface of the deflection rod 710. The vertical guide plate 73 slidably penetrates from the top surface to the bottom surface of the lower pressing plate 72. The vertical guide plate 73 is fixedly connected to the top surface of the processing table 1. The track 75 is fixedly connected to the top surface of the processing table 1. A plurality of clamping grooves are provided on the side surface of the clamping groove rod 711. A pressing spring is arranged inside the positioning block 77, and the two ends of the pressing spring are respectively connected to the positioning block 77 and the positioning cross bar 76. The pressing plate 3 drives the transverse movement frame 92 to move downward and pushes the lower pressing plate 72 to descend. The lower pressing plate 72 pushes the lower pressing plate 72 to move vertically along the vertical guide plate 73 through the return spring, so that the vertical guide plate 73 slides along the side surface of the inclined groove sliding plate 74. The vertical guide plate 73 extends into the inner side of the inclined groove on the side surface of the inclined groove sliding plate 74 and presses on the inclined groove inside the inclined groove sliding plate 74. The stressed inclined groove sliding plate 74 drives the connected positioning cross bar 76 to slide along the track 75 and approach the plate. As the positioning cross bar 76 and the positioning block 77 move together, when the positioning block 77 contacts the plate through the rubber block 78, the rubber block 78 is pushed by the reaction force of the plate to relatively slide the positioning block 77 and the positioning cross bar 76 and compress the pressing spring. Subsequently, the movement of the positioning block 77 drives the engaged deflection teeth 79 to move. At this time, the deflection teeth 79 will drive the connected deflection rod 710 to deflect, and the clamping groove rod 711 will be clamped through the deflection rod 710. The clamping grooves at different positions on the clamping groove rod 711 can be used to position PCB plates of different sizes. In addition, by using the clamping groove rod 711 to position the four corners of the plate, the shielding and cooperation restrictions on the plate positioning can be avoided to the greatest extent, and the bracket 52 is pressed to prevent the plate from shifting during the cutting process. In addition, during the swinging process of the clamping groove rod 711 with the deflection rod 710, the generated debris can be pushed into the collection holes on the processing table 1 for collection to play a role in cleaning the debris.

[0034] Working principle: By stacking, 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 delicate 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 into appropriate sizes according to the coordinate points. After the process is completed, the material is transported to a deburring device to remove the excess burrs. After removing the burrs, the overall thickness of the board is measured by laser ranging to determine whether the cut material is qualified;

[0035] The device performs a cutting process on the PCB board after it is cut by the above-mentioned cutting and grinding structure. When cutting the PCB board, the board is pushed above the processing table 1 through an external cylinder structure. The lifting structure 9 descends, driving the connected vertical cutting board 8 downward. The vertical cutting board 8 is a telescopic structure. When the vertical cutting board 8 moves downward, it will contract upward by a certain distance after contacting the board and then cut the board. Before cutting, the excess glue on the board is removed by the vertical cutting board 8, and the board is sucked by the circular turntable on the processing table 1 to rotate and adjust the orientation. After cutting the four sides of the board respectively, it is then cut by the cutting and grinding mechanism 5. Subsequently, the lifting structure 9 moves downward, driving the orientation adjustment mechanism 6 to descend, so that the cutting and grinding mechanism 5 connected to the orientation adjustment mechanism 6 approaches the surface of the PCB board through the limiting bracket 52. The cutting blade 53 will sink into the surface of the PCB board and make the limiting bracket 52 fit the surface of the cutting area. The thickness of the cutting by the cutting blade 53 is restricted by the limiting bracket 52 to prevent the cutting blade 53 from damaging the processing table 1. While the cutting blade 53 operates for cutting, the cutting blade 53 drives the pulley on the side of the grinding disc 512 to rotate through the transmission belt 513. At the same time, after the rotating shafts on both sides of the limiting bracket 52 fit the board, the contact pressure hinge rod 58 connected by the rotating shaft deflects around the connection point of the hinge seat 57. After one of the contact pressure hinge rods 58 deflects, it will drive the flipping rod 59 to deflect together. The deflected flipping rod 59 will drive the vertical groove shaft disc 510 to move away from the protective shell 51, and the vertical groove shaft disc 510 will pull the sliding piece shaft 511 to slide with the rotating shaft piece 54 connected to the outside, so that the grinding disc 512 connected to the sliding piece shaft 511 moves away from the grinding disc 512 connected to the positioning shaft 55, and the positioning shaft 55 moves relatively away from the cross key rod 56. At this time, the positioning shaft 55 rotates and drives the sliding piece shaft 511 to rotate through the connected cross key rod 56, so that the sliding piece shaft 511 rotates relative to the vertical groove shaft disc 510. The grinding disc 512 connected to the positioning shaft 55 fits one side of the cutting groove of the board for grinding, and the grinding disc 512 connected to the sliding piece shaft 511 moves away from the positioning shaft 55 to grind the burrs on the side of the other cutting groove, so as to realize the simultaneous grinding of both sides of the cutting groove of the board, improve the flatness of the cutting opening, and at the same time grind both sides of the opening together to keep the flatness of the deburred opening consistent, further improve the cutting and grinding efficiency, avoid secondary grinding. In addition, by the mutual separation of the two grinding discs 512, force is applied to the contact surface to improve the grinding effect on the side of the narrow cutting groove;

[0036] When the cutting direction of the cutting blade 53 needs to be adjusted, the control module built into the driving end 95 controls the external motor to drive the driving screw 94 to rotate, so that the driving end 95 moves to align with the touch-pressure folding rod 61 installed on the front side of the lifting frame 91. Then, the driving wheel built into the rotating shaft seat 93 controls the transverse movement frame 92 to move forward. When the touch-pressure folding rod 61 contacts the inclined guide block 68, as the transverse movement frame 92 continues to move, the touch-pressure folding rod 61 presses the inclined guide block 68. After being pressed, the inclined guide block 68 drives the connected linkage block 67 to make the torsion block 63 slide downward along the central fixed rod 66 and pull the torsion spring to stretch. When the clamping strip 64 connected to the side of the torsion block 63 is no longer restricted by the touch-pressure folding rod 61, the transverse movement frame 92 continues to move and drives the steering shaft seat 62 to continuously approach the touch-pressure folding rod 61. At this time, the touch-pressure folding rod 61 presses the top of the inclined guide block 68, pushing the inclined guide block 68 to rotate around the torsion block 63 through the connected linkage block 67. As the touch-pressure folding rod 61 pushes the top of the inclined guide block 68, the contact position between the touch-pressure folding rod 61 and the inclined guide block 68 moves to the deflection push block 69. At this time, the stretched torsion spring has a tendency to contract. The contraction of the torsion spring drives the connected torsion block 63 to slide along the guiding cutting surface 65 opened on the touch-pressure folding rod 61 until the clamping strip 64 connected to the torsion block 63 is engaged with the touch-pressure folding rod 61 again. When the driving seat plate 610 connected to the clamping strip 64 needs to be reset, the control module built into the driving end 95 controls the external motor to drive the driving screw 94, so that the driving end 95 moves to the position of the touch-pressure folding rod 61 behind the lifting frame 91, making the driving end 95 close to the touch-pressure folding rod 61 here. At this time, the touch-pressure folding rod 61 contacts the inclined guide block 68 and applies pressure, so that the inclined guide block 68 drives the torsion block 63 to move downward through the linkage block 67, making the clamping strip 64 connected to the torsion block 63 disengage from the touch-pressure folding rod 61. At this time, the torsion block 63 will be reset under the torsional action of the torsion spring. The reset of the torsion block 63 will rotate around the central fixed rod 66. After the torsion block 63 is disengaged from the engaged state by the touch-pressure of the touch-pressure folding rod 61 on the inclined guide block 68, it deflects. By adjusting the deflection, the cutting direction of the cutting blade 53 connected to the driving seat plate 610 can be adjusted. The adjustment direction mechanism is combined with the lifting structure 9 to realize automatic direction adjustment. By changing the cutting orientation of the cutting blade 53, the adjustment of the plate direction is avoided, and the steps of repositioning the cutting position after the plate adjustment are simplified. By visually compensating the cutting position of the cutting blade 53, accurate and rapid cutting can be achieved after adjusting the cutting orientation of the cutting blade 53;

[0037] When the hydraulic cylinder 4 extends downward to push the pressure application plate 3 to be pressurized, the pressure application plate 3 drives the transverse movement frame 92 to move downward and pushes the lower pressure plate 72 to descend. The lower pressure plate 72 pushes the lower pressure plate 72 to move vertically along the vertical guide plate 73 through the return spring, so that the vertical guide plate 73 slides along the side surface of the inclined groove slide plate 74. The vertical guide plate 73 extends to the inside of the inclined groove on the side surface of the inclined groove slide plate 74 and applies pressure to the inclined groove inside the inclined groove slide plate 74. The inclined groove slide plate 74 after being stressed drives the connected positioning cross bar 76 to slide along the track 75 and approach the plate. As the positioning cross bar 76 and the positioning block 77 move together, when the positioning block 77 contacts the plate through the rubber block 78, the rubber block 78 is pushed by the reaction force of the plate to cause the positioning block 77 and the positioning cross bar 76 to slide relatively and compress the pressure application spring. Subsequently, the movement of the positioning block 77 drives the meshing deflection tooth 79 to move. At this time, the deflection tooth 79 will drive the connected deflection rod 710 to deflect, and the clamping groove rod 711 will be clamped through the deflection rod 710. The clamping grooves at different positions on the clamping groove rod 711 can calibrate the placement positions of PCB plates of different sizes. In addition, by applying force to the four corners of the plate using the clamping groove rod 711, the shielding and cooperation restrictions on the plate positioning can be minimized, and the bracket 52 is pressured to prevent the plate from shifting during the cutting process. In addition, during the swinging process of the clamping groove rod 711 along with the deflection rod 710, the generated debris can be pushed into the collection holes on the processing table 1 for collection to play a role in cleaning the debris.
