Description

Technical Field

[0001] The present invention relates to the technical field of PCB board drilling machines, and in particular to a feeding device for a PCB board drilling machine and the PCB board drilling machine. Background Art

[0002] PCB board, short for printed circuit board, is the support body of electronic components and the carrier of electrical connection. It is usually composed of an insulating material base and a conductive copper foil covering it. It is used to achieve connections between electronic components. Its design and production are key steps in the manufacture of electronic equipment and directly affect the performance and reliability of the circuit system.

[0003] The existing "drilling machine" patent with publication number "CN207309004U" includes: a base frame; a workbench, arranged on the base frame, for carrying the workpiece; a drilling mechanism, including a plurality of drilling assemblies, a plurality of the drilling assemblies are arranged on the base frame at intervals, and can slide relative to the base frame along a first direction, each of the drilling assemblies includes a plurality of drilling heads, the drilling heads are used to process the workpiece, and the plurality of drilling heads are evenly spaced; and a driving assembly, connected to the drilling assembly, the driving assembly includes a driving member and a connecting rod, the driving member is located in the center of the plurality of drilling heads, and is connected to the drilling head through the connecting rod, and is used to drive the drilling head to slide relative to the base frame.

[0004] However, the above patent still has some shortcomings in actual use: when drilling the PCB board, the PCB board needs to be loaded manually, and some drilling machines are equipped with multiple workstations. Therefore, when setting up a loading device, multiple loading devices need to be set up to load the multiple workstations, which will make the equipment too large, increase the floor space, and lead to excessively high costs. In addition, the patent does not have a PCB board placement device, which makes the transportation of the PCB board difficult and the transportation efficiency poor. In addition, when using a suction cup to grab the PCB board, the suction force of the suction cup is fixed and cannot be actually adjusted according to the size of the grabbed PCB board, which may result in insufficient grabbing force. Summary of the Invention

[0010] Preferably, the gripping mechanism further comprises two first electric push rods symmetrically fixedly connected to the upper end of the second guide rail, and the movable ends of the two first electric push rods are respectively fixedly connected to the two pick-and-place plates.

[0011] Preferably, a warning light is fixedly connected to the side wall of the suction cup, and the warning light, the conductive slide plate, the conductive ring and the external power supply are electrically connected through a wire.

[0012] Preferably, a loading mechanism is installed on the machine base, and the loading mechanism includes a robotic arm, a second guide rail, a pick-and-place plate, a suction cup, a receiving platform and a placement block. The 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 the second guide rail, and the upper end of the second guide rail is symmetrically and slidingly connected to two pick-and-place plates, and the lower ends of the two pick-and-place plates are fixedly connected to multiple suction cups, and the side wall of the machine base is fixedly connected to the receiving platform, and two first guide rails are symmetrically placed on the upper end of the receiving platform, and the upper ends of the two first guide rails are symmetrically and slidingly connected to two placement blocks.

[0013] Preferably, a plurality of partition blocks are fixedly connected to the side walls of the placement block, and the side walls of the partition blocks are covered with soft pads.

[0014] Preferably, the upper end of the transport platform is fixedly connected to a hydraulic cylinder, the movable end of the hydraulic cylinder is fixedly connected to a placement plate, and a plurality of universal wheels are installed at the lower end of the transport platform, and the universal wheels have a self-locking function.

[0015] A PCB drilling machine, comprising:

[0016] A drilling machine frame, wherein the upper end of the drilling machine frame is fixedly connected to a processing table, the upper end of the processing table is fixedly connected to a plurality of processing stations, and the plurality of processing stations are extended along the length direction of the drilling machine frame, and a drilling device is installed on the side wall of the drilling machine frame, and the drilling device is used to drill holes in PCB boards.

[0017] Preferably, the side walls of the drilling machine frame are symmetrically fixedly connected to two third guide rails, the machine base is slidably connected to the two third guide rail side walls, and the two third guide rails are extended along the length direction of the drilling machine frame.

[0018] The present invention has the following beneficial effects:

[0019] 1. By setting up a loading 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 is needed to load all processing stations, without setting up multiple loading devices, which can effectively reduce costs;

[0020] 2. When the robotic arm rotates, it can synchronously grab the processed PCB board from the processing station through the suction cup, and then place it on the first guide rail above the receiving platform, so as to facilitate unloading;

[0021] 3. By setting up a gripping mechanism, the gripping force of the suction cup can be automatically adjusted according to the weight of the PCB board to be gripped. For heavier PCB boards, the suction cup will increase the suction force to prevent the PCB board from falling due to insufficient gripping force, causing damage to the PCB board;

[0022] 4. By setting up an adjustment mechanism, when the air inside the suction cup is extracted through the branch pipe and negative pressure is generated, the conductive slide will also slide to the right synchronously, and then the conductive slide will separate from the conductive ring. When the suction cup is damaged and leaks, the inside of the suction cup will be connected to the outside through the damaged part, and then the internal pressure of the suction cup will be balanced with the external pressure. At this time, the conductive slide in the suction cup cannot slide to the right, thereby maintaining contact with the conductive ring, and then the circuit is connected, and the second electric push rod will be controlled by the PLC control circuit to retract, driving the adjustment rod to slide a distance to the right. At this time, more air will be extracted from other suction cups, thereby generating stronger adsorption force to make up for the lost adsorption force of the damaged suction cup. Therefore, when more suction cups are damaged and lose adsorption force, the second electric push rod will be controlled by the PLC control circuit to retract a longer distance, so that more air is extracted from the suction cup, thereby making up for the lost adsorption force and ensuring stable grasping of the PCB board.

[0023] 5. By setting a warning light, when a suction cup is damaged, the conductive slide inside the suction cup keeps in contact with the conductive ring, so the warning light installed on the side wall of the suction cup will be powered on and light up, reminding the staff that the suction cup is damaged. It is convenient for the staff to quickly locate the damaged suction cup after production, so as to quickly repair and replace it, saving time and effort;

[0024] 6. By setting up a separator, the separator can separate the upper and lower PCB boards in the placement block, thereby preventing the PCB boards from contacting each other and causing scratches, which will affect the quality of the PCB boards;

[0025] 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 feeding, or the processed PCB boards can be removed and placed on the transport platform for rapid transportation, which is very convenient.

[0036] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Reference Figures 1-9 , a loading device for a PCB board drilling machine, comprising a machine base 1, a PCB board 2, a first guide rail 3 and a transfer platform 4, a second guide rail 6, a pick-and-place plate 7 and a plurality of suction cups 8;

[0038] The grabbing mechanism includes two slides 13 symmetrically fixedly connected to the upper end of the second guide rail 6. The inner walls of the two slides 13 are sealed and slidably connected with a slide plug 14. The slides 13 are respectively connected to the interior of multiple suction cups 8 through branch pipes 15. The branch pipes 15 are made of hoses. The side wall of the pick-up and placement plate 7 is fixedly connected with a connecting rod 16. The other end of the connecting rod 16 extends to the slide 13. The side wall of the connecting rod 16 is provided with a mounting groove 26. The inner wall of the mounting groove 26 is slidably connected with an adjusting rod 27. The other end of the adjusting rod 27 is fixedly connected to the side wall of the slide plug 14. The inner wall of the suction cup 8 is provided with a suction hole 11. The inner wall of the suction hole 11 is provided with a solenoid valve 12. The solenoid valve 12 is connected to an external control device through a PLC control circuit. The external control device can energize or de-energize the solenoid valve 12 through the PLC control circuit. This is a prior art and will not be described in detail here.

[0039] The adjustment mechanism includes a slide 28 formed on the inner wall of the suction cup 8. A conductive slide 29 is sealingly and slidably connected to the inner wall of the slide 28. A spring 30 is fixedly connected between the conductive slide 29 and the inner wall of the slide 28. A conductive ring 31 is embedded in the inner wall of the slide 28. A vent 32 is formed in the inner wall of the slide 28. A second electric push rod 34 is fixedly connected to the inner wall of the mounting groove 26. The movable end of the second electric push rod 34 is fixedly connected to the adjustment rod 27. The conductive slide 29, the conductive ring 31, the second electric push rod 34 and the external power supply are connected via a PLC control circuit.

[0040] The grabbing mechanism further includes two first electric push rods 17 symmetrically fixedly connected to the upper end of the second guide rail 6 , and the movable ends of the two first electric push rods 17 are fixedly connected to the two pick-and-place plates 7 respectively.

[0041] Furthermore, the distance between the suction cups 8 on both sides is adjusted according to the width of the PCB board 2, and the two first electric push rods 17 are driven to extend or shorten, so that the two pick-and-place plates 7 can be moved away from or closer to each other, and the distance between the suction cups 8 on both sides can be quickly adjusted, so that 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, and the suction cup 8 requires a greater suction force when grasping it. When grasping a PCB board 2 with a larger width, the distance between the suction cups 8 on both sides will be larger, and the position of the slide plug 14 in the slide cylinder 13 will be closer to the two sides, and more air inside the suction cup 8 will enter the slide cylinder 13 through the branch pipe 15, so that the air inside the suction cup 8 is less, the pressure is smaller, and the pressure difference between the inside and outside of the suction cup 8 is greater. At this time, the suction force generated by the suction cup 8 through the suction hole 11 will be greater. Therefore, for a PCB board 2 with a larger weight, the suction cup 8 will increase the suction force to prevent the PCB board 2 from falling due to insufficient grasping force, thereby damaging the PCB board 2.

[0042] It is worth mentioning that when the air inside the suction cup 8 is extracted by the branch pipe 15 and a negative pressure is generated, the conductive slide 29 will also slide to the right synchronously (such as Figure 6 As shown), the conductive slide 29 will separate from the conductive ring 31. When the suction cup 8 is damaged and leaks, the inside of the suction cup 8 will be connected to 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 29 in the suction cup 8 cannot slide to the right, and thus maintains contact with the conductive ring 31. Then, the circuit is connected, and the second electric push rod 34 is controlled by the PLC control circuit to contract, driving the adjustment rod 27 to slide to the right for a distance (as shown). Figure 7As shown in the figure), more air will be extracted from the other suction cups 8 at this time, thereby generating a stronger adsorption force to compensate for the adsorption force lost by the damaged suction cup 8. Therefore, when more suction cups 8 are damaged and lose adsorption force, the second electric push rod 34 will be controlled by the PLC control circuit to retract a longer distance, so that more air can be extracted from the suction cup 8, thereby compensating for the lost adsorption force and ensuring stable grasping of the PCB board 2.

[0043] A warning light 33 is fixedly connected to the side wall of the suction cup 8, and the warning light 33, the conductive slide plate 29, the conductive ring 31 and the external power supply are electrically connected through wires.

[0044] Furthermore, when a suction cup 8 is damaged, the conductive slide 29 inside the suction cup 8 remains in contact with the conductive ring 31, so the warning light 33 installed on the side wall of the suction cup 8 will be powered on and light up, reminding the staff that the suction cup 8 is damaged, making it convenient for the staff to quickly locate the damaged suction cup 8 after production is completed, thereby performing rapid repairs and replacements, saving time and effort.

[0045] A loading mechanism is installed on the machine base 1, which 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 robotic arm 5 to rotate is installed in the machine base 1. The end of the robotic arm 5 is fixedly connected to the second guide rail 6, and two pick-and-place plates 7 are symmetrically 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. A receiving platform 9 is fixedly connected to the side wall of the machine base 1, and two first guide rails 3 are symmetrically placed on the upper end of the receiving platform 9. Two placement blocks 10 are symmetrically slidably connected to the upper ends of the two first guide rails 3.

[0046] Furthermore, first, the PCB board 2 to be processed is placed on the placement block 10 so that it is supported on the first guide rail 3. Then, two first guide rails 3 are symmetrically placed on the receiving platform 9. The first guide rail 3 on one side can be used to place the unprocessed PCB board 2, while the first guide rail 3 on the other side is not used. When processing the PCB board 2, the driving unit in the machine base 1 drives the robot arm 5 to operate, and the suction cup 8 covers the surface of the PCB board 2 above the first guide rail 3. Then, the external control device is operated to energize the solenoid valve 12 to open. Then the suction hole 11 will absorb the PCB board 2, and then the robot arm 5 will be used to place the absorbed PCB board 2 on the processing station 22 for processing. Since the machine base 1 can slide horizontally to any position on the third guide rail 24, only one robot arm 5 is needed to load all the processing stations 22, without the need to set up multiple loading devices, which can effectively reduce costs. In addition, the PCB board 2 to be processed can be placed on the receiving platform 9 and moved together with the base 1, so when loading and unloading, the placement and transportation of the PCB board 2 are extremely convenient.

[0047] It is worth mentioning that when the robot arm 5 rotates, 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, so as to facilitate unloading.

[0048] A plurality of partition blocks 18 are fixedly connected to the side walls of the placement block 10, and the side walls of the partition blocks 18 are covered with soft pads. The partition blocks 18 can separate the upper and lower PCB boards 2 in the placement block 10, thereby preventing the PCB boards 2 from contacting each other, causing scratches, and affecting the quality of the PCB boards 2.

[0049] The upper end of the transport platform 4 is fixedly connected to a hydraulic cylinder 19, and the movable end of the hydraulic cylinder 19 is fixedly connected to a placement plate. The lower end of the transport platform 4 is installed with multiple universal wheels 20, and the universal wheels 20 have a self-locking function. The transport platform 4 can be moved at will through the universal wheels 20, so unprocessed PCB boards 2 can be placed on it for convenient feeding, or the processed PCB boards 2 can be removed and placed on the transport platform 4 for rapid transportation, which is very convenient.

[0050] A PCB drilling machine, comprising:

[0051] 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 extended along the length direction of the drilling machine frame 21, and a drilling device 23 is installed on the side wall of the drilling machine frame 21, and the drilling device 23 is used to drill holes in the PCB board 2.

[0052] Two third guide rails 24 are symmetrically fixedly connected to the side walls 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 extended along the length direction of the drilling machine frame 21 .

[0053] In the present invention, the PCB board 2 to be processed is first placed on the placement block 10 so that it is supported on the first guide rail 3. Then, two first guide rails 3 are symmetrically placed on the receiving platform 9. The first guide rail 3 on one side can be used to place the unprocessed PCB board 2, while the first guide rail 3 on the other side does not place the PCB board 2.

[0054] Then, the distance between the suction cups 8 on both sides is adjusted according to the width of the PCB board 2, and the two first electric push rods 17 are driven to extend or shorten, so that the two pick-and-place plates 7 can be moved away from or closer to each other, and the distance between the suction cups 8 on both sides can be quickly adjusted, so that it can be used to grab PCB boards 2 of different specifications.

[0055] For a PCB board 2 with a larger width, its weight is greater, and the suction cup 8 needs a greater suction force to grab it. When grabbing a PCB board 2 with a larger width, the distance between the suction cups 8 on both sides will be larger, and the position of the slide plug 14 in the slide cylinder 13 will be closer to the two sides. As a result, more air inside the suction cup 8 will enter the slide cylinder 13 through the branch pipe 15, so that there will be less air inside the suction cup 8 and the pressure will be smaller. As a result, 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 hole 11 will be greater. Therefore, for a PCB board 2 with a larger weight, the suction cup 8 will increase the suction force to prevent the PCB board 2 from falling due to insufficient grabbing force, which will cause damage to the PCB board 2.

[0056] In addition, when the air inside the suction cup 8 is extracted by the branch pipe 15 and a negative pressure is generated, the conductive slide 29 will also slide to the right synchronously (such as Figure 6 As shown), the conductive slide 29 will separate from the conductive ring 31. When the suction cup 8 is damaged and leaks, the inside of the suction cup 8 will be connected to 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 29 in the suction cup 8 cannot slide to the right, and thus maintains contact with the conductive ring 31. Then, the circuit is connected, and the second electric push rod 34 is controlled by the PLC control circuit to contract, driving the adjustment rod 27 to slide to the right for a distance (as shown). Figure 7 As shown in the figure), more air will be extracted from the other suction cups 8 at this time, thereby generating a stronger adsorption force to compensate for the adsorption force lost by the damaged suction cup 8. Therefore, when more suction cups 8 are damaged and lose adsorption force, the second electric push rod 34 will be controlled by the PLC control circuit to retract a longer distance, so that more air can be extracted from the suction cup 8, thereby compensating for the lost adsorption force and ensuring stable grasping of the PCB board 2.

[0057] And when a suction cup 8 is damaged, the conductive slide 29 in the suction cup 8 keeps in contact with the conductive ring 31, so the warning light 33 installed on the side wall of the suction cup 8 will be powered on and light up, reminding the staff that the suction cup 8 is damaged, so that the staff can quickly locate the damaged suction cup 8 after the production is completed, so as to quickly carry out repairs and replacements, saving time and effort.

[0058] 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 with the surface of the PCB board 2 above the first guide rail 3. Then, the external control device is operated to energize and open the solenoid valve 12, so that the suction hole 11 will adsorb the PCB board 2. The adsorbed PCB board 2 is then placed on the processing station 22 for processing by the robotic arm 5. Since the machine base 1 can slide horizontally to any position on the third guide rail 24, only one robotic arm 5 is needed to load all the processing stations 22. There is no need to set up multiple loading devices, which can effectively reduce costs. In addition, the PCB board 2 to be processed can be placed on the receiving platform 9 and moved together with the machine base 1. Therefore, the placement and transportation of the PCB board 2 are extremely convenient during loading and unloading.

[0059] In addition, when the robot arm 5 rotates, 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, so as to facilitate unloading.

[0060] The transport platform 4 can be moved at will by the universal wheels 20, so that unprocessed PCB boards 2 can be placed on it for easy replenishment, or the processed PCB boards 2 can be removed and placed on the transport platform 4 for rapid transportation, which is very convenient.

[0061] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
