[0002] The PCB board, full name printed circuit board, is a support for electronic components and a carrier for electrical connections. It is usually composed of an insulating material substrate and conductive copper foil covering it, and is used to realize the connection between electronic components. Its design and production are key steps in the manufacture of electronic devices, directly affecting the performance and reliability of the circuit system.

[0004] However, the above patent still has deficiencies in actual use: when drilling a PCB board, manual feeding of the PCB board is required, and some drilling machines are provided with multiple workstations. Therefore, when setting up the feeding device, multiple feeding devices need to be set up to feed multiple workstations, which will make the equipment too large, increase the floor area, and lead to too high costs. In addition, this patent does not have a placement device for the PCB board, resulting in troublesome transportation of the PCB board and poor transportation efficiency. In addition, when using a suction cup to grab the PCB board, the adsorption force of the suction cup is fixed and cannot be actually adjusted according to the size of the grabbed PCB board, and there may be a situation of insufficient grabbing force.

A vent hole is formed in the inner wall of the sliding groove. A second electric push rod is fixedly connected to the inner wall of the installation groove. The movable end of the second electric push rod is fixedly connected to the adjusting rod. The conductive sliding plate, the conductive ring, the second electric push rod and an external power supply are connected through a PLC control circuit.

[0007] Preferably, the gripping mechanism further includes two first electric push rods symmetrically and fixedly connected to the upper end of the second guide rail. The movable ends of the two first electric push rods are respectively fixedly connected to the two pick-and-place plates.

[0008] Preferably, a warning light is fixedly connected to the side wall of the suction cup. The warning light, the conductive sliding plate, the conductive ring and an external power supply are electrically connected through a wire.

[0009] Preferably, a feeding mechanism is installed on the machine base. The feeding mechanism includes a robotic arm, a second guide rail, a pick-and-place plate, a suction cup, a receiving platform and a placing block. A robotic arm is rotatably installed on the side wall of the machine base. And a driving unit for driving the robotic arm to rotate is installed in the machine base. The end of the robotic arm is fixedly connected to a second guide rail. Two pick-and-place plates are symmetrically and slidably connected to the upper end of the second guide rail. A plurality of suction cups are fixedly connected to the lower ends of the two pick-and-place plates. A receiving platform is fixedly connected to the side wall of the machine base. Two first guide rails are symmetrically placed on the upper end of the receiving platform. Two placing blocks are symmetrically and slidably connected to the upper ends of the two first guide rails.

[0010] Preferably, a plurality of partition blocks are fixedly connected to the side wall of the placing block. And a soft pad is coated on the side wall of the partition block.

[0011] Preferably, a hydraulic cylinder is fixedly connected to the upper end of the handling platform. The movable end of the hydraulic cylinder is fixedly connected to a placing plate. A plurality of universal wheels are installed at the lower end of the handling platform. And the universal wheels have a self-locking function.

[0012] A PCB drilling machine, comprising: The drilling machine frame, a processing table is fixedly connected to the upper end of the drilling machine frame, a plurality of processing stations are fixedly connected to the upper end of the processing table, and the plurality of processing stations are arranged along the length direction of the drilling machine frame. A drilling device is installed on the side wall of the drilling machine frame, and the drilling device is used for drilling the PCB board.

[0013] Preferably, two third guide rails are symmetrically and fixedly connected to the side wall of the drilling machine frame. The machine base is slidably connected to the side walls of the two third guide rails, and the two third guide rails are arranged along the length direction of the drilling machine frame.

[0014] The present invention has the following beneficial effects: 1. By setting the feeding mechanism, the robotic arm cooperates with the first guide rail, the second guide rail and the third guide rail, so that the robotic arm can move horizontally on the drilling machine frame. Therefore, only one robotic arm can feed all the processing stations, and there is no need to set multiple feeding devices, which can effectively reduce costs; 2. When the robotic arm rotates and operates, it can synchronously grab the processed PCB board from the processing station by the suction cup, and then place it on the first guide rail above the receiving platform, so as to facilitate discharging; 3. By setting the grasping mechanism, the grasping force of the suction cup can be automatically adjusted according to the weight of the PCB board to be grasped. For the PCB board with a greater weight, the suction cup will increase the suction force to avoid the PCB board falling due to insufficient grasping force and damaging the PCB board; 4. By setting the adjusting mechanism, when the air inside the suction cup is extracted by the branch pipe to generate negative pressure, the conductive slide plate will also slide to the right synchronously. Furthermore, the conductive slide plate will separate from the conductive ring. When the suction cup is damaged and leaks air, the inside of the suction cup will communicate with the outside through the damaged part. At this time, the internal pressure of the suction cup will be balanced with the external pressure. At this time, the conductive slide plate inside the suction cup cannot slide to the right, so it remains in contact with the conductive ring, and then the circuit is connected. The second electric push rod will be controlled to contract by the PLC control circuit, driving the adjusting rod to slide to the right for a certain distance. At this time, more air will be extracted from other suction cups, and then a stronger adsorption force will be generated to make up for the adsorption force lost by the damaged suction cup. Therefore, when more suction cups are damaged and lose the adsorption force, the second electric push rod will be controlled to contract a longer distance by the PLC control circuit, so that more air will be extracted from the suction cup, thus making up for the lost adsorption force and ensuring the stable grasping of the PCB board; 5. By setting the warning light, when a suction cup is damaged, the conductive slide plate inside the suction cup remains in contact with the conductive ring at this time. Therefore, the warning light installed on the side wall of the suction cup will be powered on and lit, reminding the staff that the suction cup has been damaged, which is convenient for the staff to quickly locate the damaged suction cup after the production is over, so as to perform quick repair and replacement, saving time and effort; 6. By setting a separator block, the separator block can separate the upper and lower PCB boards in the placement block, thereby preventing the PCB boards from contacting each other and causing scratches, thereby affecting the quality of the PCB boards; 7. By setting up a transport platform, universal wheels and hydraulic cylinders, the transport platform can be moved at will through the universal wheels, so unprocessed PCB boards can be placed on it for easy replenishment, or the processed PCB boards can be taken down and placed on the transport platform for quick transportation, which is very convenient.

DETAILED DESCRIPTION

[0017] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0018] Referring to Figures 1-9 , a loading device for a PCB drilling machine, comprising a machine base 1, a PCB board 2, a first guide rail 3, a handling table 4, a second guide rail 6, a pick-and-place board 7, and a plurality of suction cups 8; A grasping mechanism, the grasping mechanism includes two sliding cylinders 13 symmetrically and fixedly connected to the upper end of the second guide rail 6. The inner walls of the two sliding cylinders 13 are hermetically and slidably connected with sliding plugs 14. The sliding cylinders 13 are respectively internally connected to the plurality of suction cups 8 through branch pipes 15. The branch pipes 15 are made of flexible hoses. A connecting rod 16 is fixedly connected to the side wall of the pick-and-place board 7. The other end of the connecting rod 16 extends into the sliding cylinder 13. An installation groove 26 is formed in the side wall of the connecting rod 16. An adjusting rod 27 is slidably connected to the inner wall of the installation groove 26. The other end of the adjusting rod 27 is fixedly connected to the side wall of the sliding plug 14. Suction holes 11 are formed in the inner wall of the suction cup 8. Electromagnetic valves 12 are installed on the inner walls of the suction holes 11. The electromagnetic valves 12 are connected to an external control device through a PLC control circuit. The external control device can energize or de-energize the electromagnetic valves 12 through the PLC control circuit, which is prior art and will not be elaborated herein. An adjusting mechanism, the adjusting mechanism includes a sliding groove 28 formed in the inner wall of the suction cup 8. A conductive sliding plate 29 is hermetically and slidably connected to the inner wall of the sliding groove 28. A spring 30 is fixedly connected between the conductive sliding plate 29 and the inner wall of the sliding groove 28. A conductive ring 31 is embedded in the inner wall of the sliding groove 28. A vent hole 32 is formed in the inner wall of the sliding groove 28. A second electric push rod 34 is fixedly connected to the inner wall of the installation groove 26. The movable end of the second electric push rod 34 is fixedly connected to the adjusting rod 27. The conductive sliding plate 29, the conductive ring 31, the second electric push rod 34, and an external power source are connected through a PLC control circuit. The grasping mechanism further includes two first electric push rods 17 symmetrically and fixedly connected to the upper end of the second guide rail 6. The movable ends of the two first electric push rods 17 are respectively fixedly connected to the two pick-and-place boards 7.

[0019] Furthermore, the distance between the two side suction cups 8 is adjusted according to the width of the PCB board 2. By driving the two first electric push rods 17 to extend or shorten, the two pick-and-place boards 7 can be made to move away from or closer to each other, thereby quickly adjusting the distance between the two side suction cups 8. Thus, it can be applied to the grasping of PCB boards 2 of different specifications. For a PCB board 2 with a larger width, its weight is greater. At this time, a greater suction force is required when the suction cup 8 grasps it. When grasping a PCB board 2 with a larger width, the distance between the two side suction cups 8 will be greater. At this time, the position of the sliding plug 14 in the sliding cylinder 13 will be closer to both sides. Furthermore, more air inside the suction cup 8 will enter the sliding cylinder 13 through the branch pipe 15, resulting in less air and lower pressure inside the suction cup 8. Consequently, the pressure difference between the inside and outside of the suction cup 8 will be greater, and the suction force generated by the suction cup 8 through the suction holes 11 will be greater. Therefore, for a PCB board 2 with a greater weight, the suction cup 8 will increase the suction force to prevent the PCB board 2 from falling due to insufficient grasping force and damaging the PCB board 2.

[0020] It is worth mentioning that when the air inside the suction cup 8 is extracted by the branch pipe 15 to generate negative pressure, the conductive sliding plate 29 will also slide to the right synchronously (as Figure 6 shown). Furthermore, the conductive sliding plate 29 will separate from the conductive ring 31. When the suction cup 8 is damaged and leaks air, the inside of the suction cup 8 will communicate with the outside through the damaged part. At this time, the pressure inside the suction cup 8 will be balanced with the outside pressure. At this time, the conductive sliding plate 29 inside the suction cup 8 will not be able to slide to the right and will thus remain in contact with the conductive ring 31. Consequently, the circuit is connected, and the second electric push rod 34 will be controlled by the PLC control circuit to contract, driving the adjusting rod 27 to slide to the right by a certain distance (as Figure 7 shown). At this time, more air will be extracted from other suction cups 8, generating a stronger adsorption force to make up for the adsorption force lost by the damaged suction cup 8. Therefore, when more suction cups 8 are damaged and lose the adsorption force, the second electric push rod 34 will be controlled by the PLC control circuit to contract a longer distance, causing more air to be extracted from the suction cups 8 to make up for the lost adsorption force and ensuring the stable grasping of the PCB board 2.

[0021] A warning light 33 is fixedly connected to the side wall of the suction cup 8. The warning light 33, the conductive sliding plate 29, the conductive ring 31, and the external power supply are electrically connected by wires.

[0022] Furthermore, when a suction cup 8 is damaged, the conductive sliding plate 29 inside the suction cup 8 remains in contact with the conductive ring 31. Therefore, the warning light 33 installed on the side wall of the suction cup 8 will be powered on and illuminated, reminding the staff that the suction cup 8 has been damaged, facilitating the staff to quickly locate the damaged suction cup 8 after the production is completed, and thus enabling quick repair and replacement, saving time and effort.

[0023] A feeding mechanism is installed on the machine base 1. The feeding mechanism includes a robotic arm 5, a second guide rail 6, a pick-and-place plate 7, a suction cup 8, a receiving platform 9, and a placement block 10. The robotic arm 5 is rotatably installed on the side wall of the machine base 1, and a driving unit for driving the rotation of the robotic arm 5 is installed inside the machine base 1. The end of the robotic arm 5 is fixedly connected to the second guide rail 6. Two pick-and-place plates 7 are symmetrically and slidably connected to the upper end of the second guide rail 6. A plurality of suction cups 8 are fixedly connected to the lower ends of the two pick-and-place plates 7. The side wall of the machine base 1 is fixedly connected to the receiving platform 9. Two first guide rails 3 are symmetrically placed on the upper end of the receiving platform 9. Two placement blocks 10 are symmetrically and slidably connected to the upper ends of the two first guide rails 3.

[0024] Further, first place the PCB board 2 to be processed on the placement block 10 so that it is carried on the first guide rail 3. Then symmetrically place two first guide rails 3 on the receiving platform 9. The first guide rail 3 on one side can place the unprocessed PCB board 2, and the first guide rail 3 on the other side does not place the PCB board 2. When processing the PCB board 2, the driving unit inside the machine base 1 drives the robotic arm 5 to operate, covering the suction cup 8 on the surface of the PCB board 2 above the first guide rail 3. Then operate the external control device to make the solenoid valve 12 energized and opened, and then the suction holes 11 will adsorb the PCB board 2. Then use the robotic arm 5 to place the adsorbed PCB board 2 on the processing station 22 for processing. Since the machine base 1 can slide horizontally on the third guide rail 24 to any position, only one robotic arm 5 is needed to feed all the processing stations 22, eliminating the need to set up multiple feeding devices, effectively reducing costs, and the PCB board 2 to be processed can be placed on the receiving platform 9 and moved together with the machine base 1. Therefore, when loading and unloading, the placement and transfer of the PCB board 2 are extremely convenient.

[0025] It is worth mentioning that when the robotic arm 5 rotates and operates, it can synchronously grab the processed PCB board 2 from the processing station 22 through the suction cup 8 and then place it on the empty first guide rail 3 on the receiving platform 9, facilitating unloading.

[0026] A plurality of partition blocks 18 are fixedly connected to the side wall of the placement block 10, and the side walls of the partition blocks 18 are coated with soft pads. The partition blocks 18 can separate the upper and lower two PCB boards 2 inside the placement block 10, thus preventing the PCB boards 2 from contacting each other and causing scratches, which would affect the quality of the PCB boards 2.

[0027] A hydraulic cylinder 19 is fixedly connected to the upper end of the handling platform 4. The movable end of the hydraulic cylinder 19 is fixedly connected to a placement plate. A plurality of universal wheels 20 are installed at the lower end of the handling platform 4, and the universal wheels 20 have a self-locking function. The handling platform 4 can be moved freely through the universal wheels 20. Therefore, unprocessed PCB boards 2 can be placed above it for convenient replenishment of materials, or the processed PCB boards 2 can be removed and placed on the handling platform 4 for rapid transfer, which is very convenient.

[0028] A PCB drilling machine, comprising: A drilling machine frame 21, a processing table 25 is fixedly connected to the upper end of the drilling machine frame 21. A plurality of processing stations 22 are fixedly connected to the upper end of the processing table 25, and the plurality of processing stations 22 are arranged along the length direction of the drilling machine frame 21. A drilling device 23 is installed on the side wall of the drilling machine frame 21, and the drilling device 23 is used for drilling the PCB board 2.

[0029] Two third guide rails 24 are symmetrically and fixedly connected to the side wall of the drilling machine frame 21. The machine base 1 is slidably connected to the side walls of the two third guide rails 24, and the two third guide rails 24 are arranged along the length direction of the drilling machine frame 21.

[0030] In the present invention, first, the PCB board 2 to be processed is placed on the placement block 10 so that it is carried on the first guide rail 3. Then, two first guide rails 3 are symmetrically placed on the receiving platform 9. The unprocessed PCB board 2 can be placed on one side of the first guide rail 3, and no PCB board 2 is placed on the other side of the first guide rail 3.

[0031] Then, the distance between the two suction cups 8 on both sides is adjusted according to the width of the PCB board 2. By driving the two first electric push rods 17 to extend or shorten, the two pick-and-place plates 7 can be made to move away from or close to each other, thereby quickly adjusting the distance between the two suction cups 8 on both sides, and thus it can be applied to the grasping of PCB boards 2 of different specifications.

[0032] For a PCB board 2 with a larger width, its weight is greater. At this time, a greater suction force is required when the suction cup 8 grasps it. When grasping a PCB board 2 with a larger width, the distance between the two suction cups 8 on both sides will be greater. At this time, the position of the sliding plug 14 in the sliding cylinder 13 will be closer to both sides. As a result, more air in the suction cup 8 will enter the sliding cylinder 13 through the branch pipe 15, so that the air in the suction cup 8 is less and the pressure is smaller. Furthermore, the pressure difference between the inside and outside of the suction cup 8 will be greater. At this time, the suction force generated by the suction cup 8 through the suction holes 11 will be greater. Therefore, for a PCB board 2 with a greater weight, the suction cup 8 will increase the suction force to avoid the PCB board 2 falling due to insufficient grasping force and damaging the PCB board 2.

[0033] In addition, when the air inside the suction cup 8 is extracted by the branch pipe 15 to generate negative pressure, the conductive slide plate 29 will also slide to the right synchronously (as Figure 6 shown), and then the conductive slide plate 29 will separate from the conductive ring 31. When the suction cup 8 is damaged and leaks air, the inside of the suction cup 8 will communicate with the outside through the damaged part. At this time, the internal pressure of the suction cup 8 will be balanced with the external pressure. At this time, the conductive slide plate 29 inside the suction cup 8 cannot slide to the right, so it remains in contact with the conductive ring 31, and then the circuit is connected. The second electric push rod 34 will be controlled to contract by the PLC control circuit, driving the adjusting rod 27 to slide to the right for a certain distance (as Figure 7 shown). At this time, more air will be pumped out of the other suction cups 8, generating a stronger adsorption force to make up for the adsorption force lost by the damaged suction cup 8. Therefore, when more suction cups 8 are damaged and lose the adsorption force, the second electric push rod 34 will be controlled to contract a longer distance by the PLC control circuit, so that more air will be pumped out of the suction cup 8, making up for the lost adsorption force and ensuring the stable grasping of the PCB board 2.

[0034] Moreover, when a suction cup 8 is damaged, the conductive slide plate 29 inside the suction cup 8 remains in contact with the conductive ring 31. Therefore, the warning light 33 installed on the side wall of the suction cup 8 will be powered on and lit, reminding the staff that the suction cup 8 has been damaged, which is convenient for the staff to quickly locate the damaged suction cup 8 after the production is completed, so as to carry out quick repair and replacement, saving time and effort.

[0035] When processing the PCB board 2, the driving unit in the machine base 1 drives the robotic arm 5 to operate, covering the suction cup 8 on the surface of the PCB board 2 above the first guide rail 3. Then, operate the external control device to make the solenoid valve 12 energized and opened. Then, the suction holes 11 will adsorb the PCB board 2. Then, use the robotic arm 5 to place the adsorbed PCB board 2 on the processing station 22 for processing. Since the machine base 1 can slide horizontally on the third guide rail 24 to any position, only one robotic arm 5 is needed to load materials for all the processing stations 22, eliminating the need to set up multiple loading devices, which can effectively reduce costs. And the PCB board 2 to be processed can be placed on the receiving platform 9 and moved together with the machine base 1. Therefore, when loading and unloading, the placement and transfer of the PCB board 2 are extremely convenient.

[0036] In addition, when the robotic arm 5 rotates and operates, it can synchronously grab the processed PCB board 2 from the processing station 22 through the suction cup 8, and then place it on the first guide rail 3 above the receiving platform 9, which is convenient for unloading.

[0037] The handling platform 4 can be moved freely through the universal wheels 20. Therefore, unprocessed PCB boards 2 can be placed above it, which is convenient for replenishing materials. Or the processed PCB boards 2 can be removed and placed on the handling platform 4 for rapid transfer, both of which are very convenient.

[0038] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
