[0023] Embodiment
[0024] In the prior art, the suction cup group of the board feeding and receiving machine generally uses a shaking mechanism and a blowing mechanism to achieve the function of separating boards. However, due to the special material and process of the boards, and the lack of air between the boards when stacked, even if the board separation work is carried out from multiple dimensions, a good effect still cannot be achieved. Sometimes, manual board separation is even required, which greatly affects the working efficiency of the board feeding machine.
[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: a sucker group eight-claw type board splitting mechanism, which includes a fixed frame 1. A first mounting seat 2 and a second mounting seat 3 are respectively installed on the top of the fixed frame 1. Air cylinders 4 are installed on both the first mounting seat 2 and the second mounting seat 3. The piston rod of the air cylinder 4 is fixedly connected with a connecting rod 5. One end of the connecting rod 5 is fixedly connected with a connecting frame 6. A sucker body 7 is installed on the connecting frame 6. One end of the bottom of the fixed frame 1 and the bottom of the second mounting seat 3 are both fixedly connected with a fixing plate 8. Guide columns 9 are movably penetrated through both ends of the fixing plate 8. One end of the guide column 9 is fixedly connected to the top of the connecting frame 6. A limiting component is arranged on one side of the second mounting seat 3. Inclined surfaces are arranged on one side of the first mounting seat 2 and the second mounting seat 3. The air cylinder 4 is installed on the inclined surface. A long through groove is opened at the other end of the fixed frame 1. One of the connecting rods 5 movably penetrates through the inside of the long through groove; by moving the sucker body 7 above the PCB board, pressing the bottom of the sucker body 7 tightly against the PCB board, sucking the PCB board through the sucker body 7, and then resetting the piston rod of the air cylinder 4, the connecting frame 6 at one end of the connecting rod 5 is driven to move, and the sucker body 7 drives both ends of the PCB board to lift upward towards the middle, causing the PCB board to bend. Picking up the PCB board from both sides can effectively solve the problem that the splitting is affected by the pressure due to no gap and no air between the boards, greatly improving the splitting effect and enhancing the equipment efficiency. After the splitting is completed, the air cylinder 4 returns to the extended state, making the PCB board no longer bend, and then the board is put in.
[0026] By setting the limiting component, it is convenient to adjust the position of the second mounting seat 3, and the splitting of PCB boards with different sizes can be carried out, improving the versatility of the device; the limiting component includes a connecting column 11, a telescopic spring 12 and a pressing plate 13. Two mounting grooves 19 are opened at one end of the second mounting seat 3. Deep grooves 10 are opened at the top sides of the interiors of the two mounting grooves 19. The connecting column 11 is movably inserted into the inside of the deep groove 10. The telescopic spring 12 is movably sleeved on the outside of the connecting column 11. The pressing plate 13 is fixedly connected to the bottom end of the connecting column 11. A guide groove 14 is opened on one side of the second mounting seat 3. A push column 15 is movably inserted into the inside of the guide groove 14. A pushing component is arranged at one end of the second mounting seat 3. The pushing component includes two mounting frames 16, a pressing block 17 and a push rod 18. The two mounting frames 16 are fixedly connected to one end of the second mounting seat 3. The pressing block 17 is movably connected to the inside of the mounting frame 16 through a shaft. The push rod 18 is fixedly connected to the outside of the pressing block 17; by pressing down the push rod 18, the push rod 18 drives the pressing block 17 to rotate inside the mounting frame 16, the convex end of the pressing block 17 disengages from the inside of the limiting groove, the telescopic spring 12 drives the connecting column 11 to reset, and the pressing plate 13 disengages from the outside of the fixed frame 1. At this time, the second mounting seat 3 can be pushed to move outside the fixed frame 1, and the position of the second mounting seat 3 can be adjusted.
[0027] One end of the telescopic spring 12 is fixedly connected to the top side of the pressing plate 13, and the other end of the telescopic spring 12 is fixedly connected to the inner side of the deep groove 10. By arranging the telescopic spring 12, the connecting column 11 can be driven to reset, and then the second mounting seat 3 can be moved. A limiting groove is provided at one end of the push column 15, and the other end of the push column 15 abuts against the top end of the connecting column 11. After the position of the second mounting seat 3 is adjusted, by pushing the push rod 18 upward, the push rod 18 drives the extrusion block 17 to rotate, so that the convex end of the extrusion block 17 abuts in the limiting groove of the push column 15, thereby pushing the push column 15 to move inside the guiding groove 14. The push column 15 pushes the connecting column 11 to move inside the deep groove 10, so that the pressing plate 13 abuts against the top of the fixing frame 1, and the fixing of the position of the second mounting seat 3 can be completed.
[0028] For the working principle or structural principle, when the PCB board needs to be separated, the suction cup body 7 is moved above the PCB board, and the bottom of the suction cup body 7 is closely attached to the PCB board. The PCB board is sucked by the suction cup body 7. Then, the solenoid valve of the air cylinder 4 is started by controlling through the switch group, so that the piston rod of the air cylinder 4 resets, thereby driving the connecting frame 6 at one end of the connecting rod 5 to move. The suction cup body 7 drives both ends of the PCB board to be lifted upward to the middle, so that the PCB board is bent. Picking up the PCB board from both sides can effectively solve the problem that the separation of the boards is affected by the pressure due to no gap and no air between the boards, greatly improving the separation effect and enhancing the equipment efficiency. After the separation is completed, the air cylinder 4 returns to the extended state, so that the PCB board is no longer bent, and then the board is inserted.
[0029] When the PCB boards of different sizes need to be separated, by pressing the push rod 18 downward, the push rod 18 drives the extrusion block 17 to rotate inside the mounting frame 16, so that the convex end of the extrusion block 17 disengages from the inside of the limiting groove. The telescopic spring 12 drives the connecting column 11 to reset, so that the pressing plate 13 disengages from the outside of the fixing frame 1. At this time, the second mounting seat 3 can be pushed to move outside the fixing frame 1, and the position of the second mounting seat 3 can be adjusted, enabling the separation of PCB boards of different sizes and improving the versatility of the device. After the position of the second mounting seat 3 is adjusted, by pushing the push rod 18 upward, the push rod 18 drives the extrusion block 17 to rotate, so that the convex end of the extrusion block 17 abuts in the limiting groove of the push column 15, thereby pushing the push column 15 to move inside the guiding groove 14. The push column 15 pushes the connecting column 11 to move inside the deep groove 10, so that the pressing plate 13 abuts against the top of the fixing frame 1, and the fixing of the position of the second mounting seat 3 can be completed.
