[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: a high-precision PCB board splitting machine includes an operating table 1. A support table 2 is fixedly connected to the front end of the operating table 1. The PCB board to be processed is placed through the support table 2. A cylinder 3 is fixedly connected to the inner wall of the right end of the support table 2. The driving end of the cylinder 3 is fixedly connected to a moving block 4. When the cylinder 3 starts, it will drive the moving block 4 to move. The outside of the moving block 4 is slidably connected to the inner wall of the support table 2, so that the moving block 4 slides more stably. A cylinder 5 is fixedly connected to the rear end of the moving block 4. The movement of the moving block 4 can drive the cylinder 5 to move. An extension plate 6 is slidably connected to the top of the support table 2. The sliding of the extension plate 6 is restricted by the support table 2. A slot hole 7 is provided outside the extension plate 6. The outside of the cylinder 5 is slidably connected to the inner wall of the slot hole 7. In this way, the movement of the cylinder 5 can move the extension plate 6 through the slot hole 7. A lower pressing plate 8 is fixedly connected to the top of the extension plate 6. When the extension plate 6 moves, it will drive the lower pressing plate 8 to move. A plurality of first springs 9 are provided inside the lower pressing plate 8. A telescopic plate 10 is slidably connected to the inner wall of the lower pressing plate 8. The telescopic plate 10 is restricted by the lower pressing plate 8. One end of the first spring 9 is fixedly connected to one side of the lower pressing plate 8, and the other end of the first spring 9 is fixedly connected to one side of the telescopic plate 10. The movement of the telescopic plate 10 can compress the first spring 9.
[0025] A rubber plate 11 is fixedly connected to the bottom of the telescopic plate 10. The rubber plate 11 of the copper hot pot clamps the PCB board placed on the top of the support table 2. The outside of the rubber plate 11 is slidably connected to the bottom of the lower pressing plate 8, so that the rubber plate 11 can contract into the inside of the lower pressing plate 8. The inner wall of the operating table 1 is rotatably connected with a feeding assembly. The feeding assembly includes a conveyor belt 12. The conveyor belt 12 is rotatably connected to the inner wall of the support table 2. Two feeding plates 13 are rotatably connected to the outside of the conveyor belt 12. The rotation of the conveyor belt 12 can drive the feeding plates 13 to move. The movement of the feeding plates 13 pushes the PCB board. And a torsion spring is arranged at the part where the feeding plate 13 is connected to the conveyor belt 12, so that the feeding plate 13 can rotate when being pressed by the rubber plate 11 and can rebound when released. When the air cylinder 3 is started, it will drive the moving block 4 to move, and the movement of the moving block 4 can drive the cylinder 5 to move. At this time, the movement of the cylinder 5 will slide on the inner wall of the slot hole 7, so that the extension plate 6 continuously descends. The descent of the extension plate 6 will drive the lower pressing plate 8 to descend, so that the rubber plate 11 will clamp the placed PCB board under the movement of the lower pressing plate 8. After clamping, the rubber plate 11 will push the telescopic plate 10 to squeeze the first spring 9, so that the first spring 9 deforms. And through the deformation of the first spring 9 and the characteristics of the rubber plate 11, the PCB board can be clamped without being damaged.
[0026] Reference Figures 4 - 5 , a motorized slide rail 14 is fixedly connected to the top inner wall of the operating table 1. A sliding block 15 is slidably connected to the bottom of the motorized slide rail 14. The cutting tool can be moved by sliding the sliding block 15 at the bottom of the motorized slide rail 14. A hydraulic cylinder 16 is fixedly connected to the bottom of the sliding block 15. The driving end of the hydraulic cylinder 16 is fixedly connected to a support frame 17. The start of the hydraulic cylinder 16 can drive the support frame 17 to move. A motor 18 is fixedly connected to the inner wall of the support frame 17. The driving end of the motor 18 is detachably connected to a cutting head 19. When the motor 18 is started, it will drive the cutting head 19 to perform cutting operations. Disassembly components are slidably connected to the front and rear ends of the motor 18. The disassembly component includes two control rods 20. The two control rods 20 are respectively slidably connected to the front and rear ends of the motor 18. The disassembly of the cutting head 19 can be controlled by sliding the control rods 20.
[0027] On the adjacent sides of both control rods 20, there are fixedly connected push plates 21. When the control rods 20 move, they will drive the push plates 21 to move. Inside the inner wall of the motor 18, there are rotatably connected two rotating rods 22. The outer part of the push plate 21 is slidably connected to the inner wall of the motor 18, which enables the push plate 21 to be stable. The inner side wall of the push plate 21 is in contact with the outer side wall of the rotating rod 22. By the movement of the push plate 21, the rotating rod 22 is driven to rotate. On the adjacent sides of the left ends of the two rotating rods 22, there is fixedly connected a second spring 23. Through the second spring 23, the rotating rod 22 can be reset and provide a clamping force. The outer part of the rotating rod 22 is engaged with the inner wall of the cutting head 19, so that the cutting head 19 is installed and fixed. By pressing the control rod 20, when the control rod 20 is pressed, it will drive the push plate 21 to move. By the movement of the push plate 21, the rotating rod 22 is driven to rotate. When the rotating rod 22 rotates, the engagement with the cutting head 19 is cancelled, so that the cutting head 19 can be removed to complete the disassembly and replacement.
[0028] Working principle: First, place the PCB board on the top of the support table 2 when in use. At this time, start the cylinder 3. By starting the cylinder 3, the moving block 4 will be driven to move, and the movement of the moving block 4 can drive the cylinder 5 to move. At this time, the movement of the cylinder 5 will slide on the inner wall of the slot hole 7, so that the extension plate 6 continuously descends. By the descent of the extension plate 6, the lower pressing plate 8 will be driven to descend. Thus, under the movement of the lower pressing plate 8, the rubber plate 11 will clamp the placed PCB board. After clamping, the rubber plate 11 will push the telescopic plate 10 to squeeze the first spring 9, so that the first spring 9 deforms. And through the deformation of the first spring 9 and the characteristics of the rubber plate 11, the PCB board can be clamped without causing damage to the PCB board. At this time, start the hydraulic cylinder 16 to lower the support frame 17. By the movement of the support frame 17, the cutting head 19 is moved to a suitable position, and then start the motor 18 to drive the cutting head 19 to cut. During the cutting process, the cutting head 19 is moved by the sliding block 15 sliding on the outside of the electric slide rail 14, so as to cut the PCB board. After cutting, the clamping of the PCB board is cancelled. Start the conveyor belt 12. By the rotation of the conveyor belt 12, the feeding plate 13 is driven to move. Thus, under the movement of the feeding plate 13, the PCB board can be pushed to move. After the moved PCB board is clamped, the cutting operation is carried out again, so that there is no need for manual adjustment of the PCB board. When the cutting head 19 needs to be replaced and repaired after long-term use, by pressing the control rod 20, when the control rod 20 is pressed, it will drive the push plate 21 to move. By the movement of the push plate 21, the rotating rod 22 is driven to rotate. When the rotating rod 22 rotates, the engagement with the cutting head 19 is cancelled, so that the cutting head 19 can be removed to complete the disassembly and replacement.
