It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] Embodiment 1: A copper-clad laminate cutting machine for circuit board processing, such as Figure 1-6 As shown, it includes a bottom plate 1, a support frame 2, a support frame 21, a material discharge table 22, a conveying device 3, a fixed plate 4, a mounting frame 6, a hydraulic cylinder 7, a cold cutting knife 8, a cylinder 9 and a support block 10. The top of the bottom plate 1 is symmetrically fixedly connected with a support frame 2 in the front and rear directions, and the rear part of the front support frame 2 is fixedly connected with a support frame 21. The left and right sides of the top of the support frame 21 are provided with material discharge tables 22. The left material discharge table 22 is used to place the copper clad laminate to be cut, and the right material discharge table 22 is used to place the cut copper clad laminate. The front part of the rear support frame 2 is fixedly connected with a conveying device 3 for transferring the copper clad laminate in a horizontal direction. The left part of the conveying device 3 is fixedly connected with a fixed plate 4 for placing the copper clad laminate flatly when loading. The conveying device 3 is composed of a mounting frame, two synchronous belt groups and a driving motor. Driven by the driving motor, the conveying direction of the materials on the two synchronous belts is from left to right. A mounting frame 6 is fixedly connected to the conveying device 3. A hydraulic cylinder 7 providing a large cutting force is installed on the upper part of the mounting frame 6. A cold cutter 8 for cutting the copper clad laminate into sections is fixedly connected to the lower part of the hydraulic rod of the hydraulic cylinder 7. A cylinder 9 is installed at the lower part of the mounting frame 6. A support block 10 for lifting the cutting part of the copper clad laminate to a certain height to prevent the cold cutter 8 from squeezing the synchronous belt is fixedly connected to the upper part of the movable rod of the cylinder 9. The front and rear sides of the support block 10 are located between the two synchronous belts. When moving upward, it does not contact the synchronous belt. A strip groove that fits the lower part of the cold cutter 8 is opened in the support block 10.

[0024] Initially, the copper-clad laminates that need to be cut are neatly stacked and placed on the unloading table 22 on the left. When the copper-clad laminates need to be cut, first move the top copper-clad laminate on the left unloading table 22 to the fixed plate 4. The copper-clad laminate is placed flat on the fixed plate 4. At this time, the copper-clad laminate is relatively parallel to the ground. Then, it is pushed into the conveying device 3 so that the bottom side of the copper-clad laminate contacts the top of the two synchronous belts in the conveying device 3. Then, the driving motor on the conveying device 3 is started, and the driving motor rotates, driving the synchronous belt to rotate. There is a certain friction between the synchronous belt and the copper-clad laminate, which drives the copper-clad laminate to move horizontally to the right. During this process, the copper-clad laminate on the synchronous belt will pass through the inner side of the connecting frame 11. At this time, the copper-clad laminate is located between the cold cutting knife 8 and the support plate 5. When the length of the copper-clad laminate on the right side of the support plate 5 is the required cutting length, The control drive motor stops and the synchronous belt stops conveying, then the hydraulic cylinder 7 is started and the control hydraulic cylinder 7 extends the hydraulic rod downward, the hydraulic rod drives the cold cutter 8 to cut the copper clad laminate on the synchronous belt downward, the synchronous cylinder 9 extends a movable rod upward, lifts the support block 10 slightly, so that the copper clad laminate is slightly higher than the synchronous belt, with the cooperation of the cold cutter 8 and the support block 10, the copper clad laminate is cut into two pieces, then the control hydraulic cylinder 7 and cylinder 9 retract the hydraulic rod and the movable rod, drive the cold cutter 8 and the support block 10 to move and reset, then control the drive motor to continue running, drive the synchronous belt to move the cut copper clad laminate to the right, when the two cut copper clad laminates are moved to the right part of the synchronous belt by the conveying device 3, the control motor stops, then the cut copper clad laminates are unloaded and neatly stacked on the unloading table 22 on the right, completing the cutting work.

[0025] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 5 and Figure 6As shown, it also includes a fixed frame 101, a connecting frame 11, a cylinder 12, a guide rod 13, a suction cup frame 14, a rack 15, a gear 16 and a transmission assembly 17. A fixed frame 101 for supporting and guiding is welded between the upper parts of the support frame 101. A strip-shaped slot is opened in the fixed frame 101. A connecting frame 11 is slidably provided on the upper part of the fixed frame. The connecting frame 11 is used for rigidly connecting and supporting the material-taking component on the cutting machine. Cylinders 12 are provided on both sides of the connecting frame 11. The lower part of the movable rod of the cylinder 12 is connected to the suction cup frame 14. The top of the suction cup frame 14 is connected to two guide rods 13 that play a role in maintaining stability and guiding. The rods 13 are all slidably connected to the connecting frame 11 on the same side. The suction cup frame 14 is composed of a connecting plate and a plurality of suction cups. The two cylinders 12 are used for loading and unloading respectively, driving the suction cup frame 14 to pick up and place the copper clad board. A rack 15 is fixed in the slot on the fixed frame 101. A gear 16 is rotatably provided on the connecting frame 11, and the gear 16 is meshed with the rack 15. A transmission assembly 17 is provided on the upper part of the connecting frame 11. The transmission assembly 17 is composed of a transmission motor and a group of pulley groups. The gear 16 is driven to rotate by the transmission motor through the pulley group. When the gear 16 rotates, it will drive the connecting frame 11 to move on the fixed frame 101.

[0026] like Figure 1-3 As shown, it also includes a roller 18 and a pressure plate 19. The roller 18 is rotatably provided on the upper part of the conveying device 3. The front and rear sides of the conveying device 3 are fixedly connected with pressure plates 19 to prevent the other end of the copper clad laminate from curling up when one end is rolled. The right parts of the two pressure plates 19 are close to the lower part of the rotating shaft. A roller pressing motor 181 is fixedly installed on the front side of the conveying device 3 through power. The roller pressing motor 181 is fixedly connected to the roller 18, and the roller pressing motor 181 drives the roller 18 to rotate in the direction opposite to the conveying direction of the synchronous belt.

[0027] like Figure 1-3 As shown, it also includes a support plate 5, which is welded on the conveying device 3. The top of the support plate 5 is at the same height as the tops of the two synchronous belts, and two grooves with the same thickness as the two synchronous belts are opened on the support plate 5. The support plate 5 lifts the two synchronous belts to prevent the synchronous belts conveying materials from sinking and affecting the normal material collection of the suction cup frame 14 on the right.

[0028] like Figure 1 and Figure 5 As shown, a nozzle 20 is also included. The nozzles 20 that can blow out high-pressure airflow are installed on the front and rear sides of the connecting plate of the right suction cup frame 14, and the blown airflow will blow toward the surface of the copper-clad board on the conveying device 3.

[0029] Initially, the connecting frame 11 is located directly above the conveying device 3. When the copper-clad laminate placed on the left unloading platform 22 needs to be cut and loaded, the left cylinder 12 is first controlled to extend the movable rod downward to push the left suction cup frame 14 to move downward. When the suction cup on the suction cup frame 14 contacts the top copper-clad laminate stacked on the left unloading platform 22, the left cylinder 12 is controlled to stop, and then the copper-clad laminate is sucked by the suction cup. Subsequently, the movable rod of the left cylinder 12 is controlled to retract, and then the transmission motor on the transmission assembly 17 is controlled to rotate forward. The transmission motor rotates through the pulley group to drive the gear 16 to rotate, and the gear 16 and the rack 15 are connected. In the meshing state, when the gear 16 rotates, the gear 16 moves backward on the fixed rack 15, driving the connecting frame 11 to move backward and reset. When the suction cup frame 14 carrying the copper-clad laminate on the left side moves to the position just above the fixed plate 4, the transmission motor is controlled to stop, and then the cylinder 2 12 on the left side is controlled to extend the movable rod downward, and when the copper-clad laminate on the suction cup frame 14 on the left side is close to the fixed plate 4, the air source on the suction cup of the suction cup frame 14 on the left side is cut off, and the negative pressure state in the suction cup is released. Under the action of gravity, the copper-clad laminate will fall on the fixed plate 4, and the right end part of the copper-clad laminate will contact the synchronous belt, and the conveying device 3 will transport the copper-clad laminate. When the copper clad laminate is cut and transported to the right, the cut copper clad laminate on the synchronous belt will contact the pressing plate 19, and then contact the rotating shaft, and the roller pressing motor 181 is controlled to drive the rotating shaft to rotate in the opposite direction of the synchronous belt. Under the action of the pallet 5, the copper clad laminate is rolled by the roller 18. The pressing plate 19 is used to prevent one end of the copper clad laminate from tilting up when the rotating shaft contacts the copper clad laminate, so as to facilitate the rotating shaft to roll and flatten the cut copper clad laminate, so as to avoid the copper clad laminate from warping after cutting, and scratching other copper clad laminates when the materials are stacked. When the two copper clad laminates are rolled, The cylinder 2 12 on the right is controlled to extend the movable rod downward, driving the suction cup frame 14 on the right to synchronously pick up the two copper clad laminates on the synchronous belt. When picking up, the high-pressure airflow from the outside is connected to the nozzle 20. When the suction cup frame 14 is close to the copper clad laminate, the airflow blown out of the nozzle 20 will blow to the surface of the copper clad laminate to avoid solid impurities on the surface of the copper clad laminate. When stacking, indentations will appear on the lamination. Finally, it moves forward through the connecting frame 11 to stack the taken copper clad laminates on the discharge table 22 on the right. While completing the unloading, the cylinder 2 12 on the left drives the suction cup frame 14 on the left to continue the loading work, and the loading and unloading work are completed synchronously, which is more efficient.

[0030] In a preferred embodiment, the driving motor on the conveying device 3 can automatically stop and convey intermittently according to the position of the copper-clad laminate in the conveying device 3, without manual control, which is more convenient.

[0031] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
