Description

Technical Field

[0001] This invention relates to the field of PCB drilling technology, and in particular to a PCB drilling machine. Background Technology

[0002] In existing technologies, when drilling PCB boards, the boards are placed on the processing table of the drilling equipment, and drilling operations are performed using cutting tools. However, in related technologies, the boards are usually placed into the processing equipment manually, and then retrieved manually after processing. This not only results in high labor costs during processing but also low efficiency in loading and unloading the boards.

[0003] Further information related to the above technical solutions can be found in the following documents:

[0004] Patent CN1 15432342A discloses an automatic loading and unloading system and an automatic processing production line incorporating it. The automatic loading and unloading system includes a buffer platform, a loading and unloading platform, a transfer cart, and a transport trolley. The loading and unloading platform is connected to the buffer platform. Workpieces awaiting processing, temporarily stored on the transport trolley, are sequentially picked up by the transfer cart and transferred to the loading and unloading platform, then conveyed to the buffer platform. Processed workpieces buffered on the buffer platform are conveyed to the loading and unloading platform via the buffer platform, and then picked up by the transfer cart and transferred to the transport trolley. This technology has a complex structure and large equipment size, resulting in slow loading and unloading.

[0005] Patent publication CN1 12047059A discloses an automatic board loading and unloading device for a PCB drilling machine. This device transports PCBs to the drilling machine and stores the drilled PCBs. It includes a loading mechanism and a sorting and collecting mechanism, located at the front and rear ends of the PCB drilling machine, respectively. The loading mechanism corrects the position of the components and sorts them onto the corresponding PCB drilling machines. The sorting and collecting mechanism classifies and stores the drilled components. This automatic board loading and unloading device for a PCB drilling machine can identify PCBs of different specifications or models. A robotic arm then sorts the PCBs by model onto different drilling machines, avoiding deviations caused by manual loading. After drilling, the PCBs are identified by their specifications and then transferred to a transport vehicle for sorting and storage, achieving full automation and improving work efficiency and product qualification rate.

[0006] In the process of realizing this invention, the inventors discovered the following problems in the prior art:

[0007] Existing technologies do not provide overall loading and unloading of PCB board placement hoppers, have few corresponding processing stations for robotic arms, have low utilization efficiency, require the installation of multiple devices with complex structures, resulting in excessively high costs and making it difficult to improve existing PCB drilling machines. Summary of the Invention

[0008] Therefore, there is a need for an automatic feeding device for PCB drilling machines to solve the technical problems of not having an overall feeding and unloading mechanism for PCB board placement bins, having few processing stations corresponding to the robotic arm, having low utilization efficiency of the robotic arm, requiring multiple devices with complex structures, resulting in high costs, and being inconvenient to improve existing PCB drilling machines.

[0009] To achieve the above objectives, in a first aspect, the inventor provides an automatic feeding device for a PCB drilling machine, comprising:

[0010] A machine base is provided with a machining platform, and the machining platform is provided with two or more machining stations. The two or more machining stations extend along the length direction of the machine base. An auxiliary platform is provided on the front side of the machine base. The auxiliary platform is fastened to the front side of the machine tool base on the side and has the same length as the machine base, forming an integral piece.

[0011] A follow-up storage platform is mounted on an auxiliary platform and moves along the auxiliary platform;

[0012] A robotic arm assembly, disposed on the follow-up storage platform, includes a frame, a robotic arm, and a gripping unit. The robotic arm assembly slides relative to the follow-up storage platform along the direction extending from the additional platform. The gripping unit is disposed on the robotic arm and is used to grip a PCB board.

[0013] The PCB board placement compartment is detachably mounted on the follow-up storage platform. There are two PCB board placement compartments, which are respectively located on the left and right sides of the robotic arm on the follow-up storage platform. The PCB board placement compartment is used to place more than two PCB boards.

[0014] Unlike existing technologies, the above-mentioned technical solution uses an additional platform to drive a follow-up storage platform. The follow-up storage platform drives the PCB board placement bin and the robotic arm to move across multiple workstations. The PCB board placement bin is detachable. Before use, multiple unprocessed PCB boards are placed in the PCB board placement bin. The robotic arm loads PCB boards one by one at multiple workstations. After processing, the robotic arm retrieves all PCB boards and puts the processed PCB boards back into the PCB board placement bin. The entire PCB board placement bin is then unloaded and replaced with a new PCB board placement bin, which facilitates the overall loading and unloading of PCB boards and improves the efficiency of PCB board loading and unloading. At the same time, by setting the robotic arm on the follow-up storage platform, one robotic arm can correspond to multiple processing platforms, which facilitates the modification of the original equipment with minimal changes, low cost, and no need to redesign the equipment.

[0015] In one embodiment of the present invention, a sliding groove is provided on the follow-up storage platform, and the PCB board placement compartment is slidably disposed on the sliding groove of the follow-up storage platform. A stop block is provided at the rear of the PCB board placement compartment, and the width of the stop block is greater than the width of the sliding groove of the follow-up storage platform. The PCB board placement compartment is limited by the stop block.

[0016] Thus, in order to facilitate the placement of the PCB board placement bin, a sliding groove is set on the follow-up storage platform. The PCB board placement bin can only move back and forth. When it slides into the designated position, the rear stop block of the PCB board placement bin blocks it to prevent the PCB board placement bin from interfering with the processing platform.

[0017] In one embodiment of the present invention, a pressing block and a pressing cylinder are installed on the follow-up storage platform. The pressing block and the pressing cylinder are connected, and the pressing cylinder is used to drive the pressing block to press the PCB board placement compartment.

[0018] Thus, in order to ensure that the PCB board placement compartment is placed too shallowly into the sliding groove on the follow-up storage platform and to prevent the PCB board placement compartment from shifting, a pressure cylinder and a pressure block are hinged together. When the PCB board placement compartment slides into place, the compression cylinder drives the pressure block from a horizontal state to a vertical state and presses the PCB board placement compartment to fix it.

[0019] In one embodiment of the present invention, the gripping unit comprises a crossbeam, a mounting plate, a front clamping assembly, a rear clamping assembly, and a rodless cylinder. The crossbeam is a cuboid with a rodless cylinder on one side along its length. The rodless cylinder has a slider connected to the front clamping assembly. The rodless cylinder drives the front clamping assembly to slide via the slider. The mounting plate is located in the middle along the length of the crossbeam and is used to cooperate with the robotic arm. The rear clamping assembly is fixedly connected to the crossbeam.

[0020] Thus, the front clamping assembly is mounted on the sliding block of the rodless cylinder, and the clamping distance can be adjusted according to the length of the workpiece, making it convenient to clamp the PCB board.

[0021] In one embodiment of the present invention, the PCB board placement compartment is a semi-enclosed structure, consisting of a base and three movable clamping plates on the side of the baffles. The three baffles form a U-shaped structure, wherein the inner sides of the two opposing baffles are provided with slots for inserting PCB boards, and the upper part of the PCB board placement compartment is provided with space for the gripping unit to grip the PCB board.

[0022] Thus, the PCB board placement compartment has a semi-enclosed structure, which facilitates the flat pulling of the PCB board. The slots on the inner sides of the two baffles separate the PCB boards, providing convenience for the gripping unit to accurately grip a PCB board.

[0023] In one embodiment of the present invention, the PCB board placement bin and the robotic arm assembly slide along an additional platform on a follow-up storage platform. The robotic arm cooperates with the gripping unit to move the PCB board relative to the processing station between the PCB board placement bin and the processing station.

[0024] In this way, robotic arms replace manual labor, and a single robotic arm component can handle the loading and unloading of materials at all processing stations.

[0025] In one embodiment of the present invention, the additional platform has a sliding track, and the follower storage platform slides along the sliding track on the additional platform.

[0026] In this way, the robotic arm is integrated with the PCB board placement compartment and moves to different workstations via slide rails. This allows multiple workstations to complete loading and unloading with just one robotic arm, resulting in a simple overall structure and reduced costs.

[0027] In one embodiment of the present invention, the additional platform is connected to the machine tool body by bolts.

[0028] In this way, the distance between the auxiliary platform and the machine tool will not be inconsistent or non-parallel due to external forces, which facilitates the disassembly and maintenance of the auxiliary platform.

[0029] In one embodiment of the present invention, the additional platform is mounted on the floor via two legs.

[0030] This improves the stability of the additional platform.

[0031] In one embodiment of the present invention, the PCB drilling machine further includes a transport trolley, which includes a lifting platform and a clamping mechanism. The clamping mechanism is disposed on the lifting platform and is used for loading or unloading PCB boards into the placement bin.

[0032] In this way, the transportation organization can transport the PCB board placement bin to the moving storage platform, or remove the PCB board placement bin from the moving storage platform, thus realizing automated loading and unloading of the PCB board placement bin.

[0062] Invention Summary: Existing technologies do not provide overall loading and unloading of PCB board placement hoppers, resulting in fewer processing stations for robotic arms, low utilization efficiency of robotic arms, and the need to set up multiple devices with complex structures, leading to excessive costs and making it inconvenient to improve existing PCB drilling machines. The applicant's research and invention relates to an automatic loading device for PCB drilling machines and a PCB drilling machine, with the aim of improving the utilization rate of robotic arms, reducing equipment, and saving costs.

[0063] According to some embodiments of this application, please refer to Figures 1 to 7 This embodiment relates to an automatic feeding device for a PCB drilling machine, comprising:

[0064] The machine base 100 is provided with a processing platform. The processing platform is provided with two or more processing stations 101. The two or more processing stations 101 extend along the length of the machine base 100. An auxiliary platform 200 is provided on the front of the machine base 100. The auxiliary platform 200 is fastened to the front side of the base of the machine base 100 and its length is the same as that of the machine base 100, forming an integral part.

[0065] The following storage platform 300 is set on the auxiliary platform 200 and moves along the auxiliary platform 200;

[0066] A robotic arm assembly 400 is mounted on a follow-up storage platform 300. The robotic arm assembly 400 includes a frame 401, a robotic arm 402, and a gripping unit 403. The robotic arm assembly 400 slides relative to the follow-up storage platform 300 along the direction of extension of the auxiliary platform 200. The gripping unit 403 is mounted on the robotic arm 402 and is used to grip a PCB board 459.

[0067] PCB board placement compartment 500 is detachably mounted on the follow-up storage platform 300. There are two PCB board placement compartments 500, which are respectively located on the left and right sides of the robotic arm 402 on the follow-up storage platform 300. The PCB board placement compartment 500 is used to place two or more PCB boards 459.

[0068] Unlike existing technologies, the above technical solution uses an additional platform 200 to drive a follow-up storage platform 300. The follow-up storage platform 300 then moves the PCB board placement bin 500 and the robotic arm 402 across multiple workstations. The PCB board placement bin 500 is detachable. Before use, multiple unprocessed PCB boards 459 are placed in the PCB board placement bin 500. The robotic arm 402 then loads the PCB boards 459 one by one onto the multiple workstations. After processing, the robotic arm 402 then collects all the PCB boards 459. The processed PCB board 459 is placed in the PCB board placement chamber 500, and the entire PCB board placement chamber 500 is unloaded. A new PCB board placement chamber 500 is then installed, which facilitates the overall loading and unloading of the PCB board placement chamber 500 and improves the loading and unloading efficiency of the PCB board 459. At the same time, by setting the robotic arm 402 on the follow-up storage platform 300, one robotic arm 402 can correspond to multiple processing platforms, which facilitates the modification of the original equipment with small changes, low cost, and no need to redesign the equipment.

[0069] According to some embodiments of this application, optionally, a sliding groove is provided on the follow-up storage platform 300, and the PCB board placement chamber 500 is slidably disposed on the sliding groove of the follow-up storage platform 300. A stop is provided at the tail of the PCB board placement chamber 500, and the width of the stop is greater than the width of the sliding groove of the follow-up storage platform 300. The PCB board placement chamber 500 is limited by the stop.

[0070] Thus, in order to facilitate the placement of the PCB board placement chamber 500, a sliding groove is provided on the follow-up storage platform 300. The PCB board placement chamber 500 can only move back and forth. When it slides into the designated position, the rear stop block of the PCB board placement chamber 500 blocks it to prevent the PCB board placement chamber 500 from interfering with the processing platform.

[0071] According to some embodiments of this application, optionally, a pressing block 501 and a pressing cylinder 502 are installed on the follow-up storage platform 300. The pressing block 501 and the pressing cylinder 502 are connected, and the pressing cylinder 502 is used to drive the pressing block 501 to press the PCB board placement chamber 500.

[0072] Thus, in order to ensure that the PCB board placement chamber 500 is placed too shallowly into the sliding groove of the follow-up storage platform 300 and to prevent the PCB board placement chamber 500 from shifting, a pressing cylinder 502 and a pressing block 501 are hinged together. When the PCB board placement chamber 500 slides into place, the compression cylinder drives the pressing block 501 from a horizontal state to a vertical state and presses the PCB board placement chamber 500 to fix the PCB board placement chamber 500.

[0073] According to some embodiments of this application, optionally, the gripping unit 403 consists of a crossbeam 404, a clamping mounting plate 450, a front clamping assembly, a rear clamping assembly, and a rodless cylinder 451. The crossbeam 404 is a cuboid, with a rodless cylinder 451 on one side along its length. The rodless cylinder 451 has a slider 452, which is connected to the front clamping assembly. The rodless cylinder 451 drives the front clamping assembly to slide via the slider 452. The clamping mounting plate 450 is positioned along the length of the crossbeam 404. In the middle, the clamp mounting plate 450 is used to cooperate with the robotic arm 402. The rear clamping assembly is fixedly connected to the crossbeam 404. The front clamping assembly includes a first V-shaped pressure block 453, a first workpiece pin 460, a first pressure cylinder 454 and a first elastic pressure block 455. The rear clamping assembly includes a second V-shaped pressure block 453, a second workpiece pin 460, a second pressure cylinder 454, a second elastic pressure block 455, a corner locking cylinder 456, an upper clamping column 457 and a swinging pressure block 458.

[0074] Thus, the front clamping assembly is mounted on the slider 452 of the rodless cylinder 451, allowing adjustment of the clamping distance according to the workpiece length for convenient clamping of the PCB board 459. The first V-shaped pressure block 453 and the second V-shaped pressure block 453 sink into the groove on the processing station 101, confirming contact between the first workpiece pin 460 and the second workpiece pin 460. The rodless cylinder 451 moves, and when it confirms that the PCB board 459 is clamped, the slider 452 drives the front clamping assembly to retract, causing the first V-shaped block 452 of the front clamping assembly to... 3. The lower part of the second V-shaped block 453 extends to the lower part of the PCB board 459 and contacts the workpiece pin, clamping the PCB board 459. After the PCB board 459 is raised to a height of about 30mm, the two corner locking cylinders 456 in the rear clamping assembly drive the two swinging pressure blocks 458 to move. The swinging pressure blocks rotate 90 degrees and extend to the lower part of the PCB board 459 and press the PCB board 459. After a delay of about 1 second, the first pressure cylinder 454 and the second pressure cylinder 454 retract, and the rear clamping assembly switches to two-point clamping by the swinging pressure blocks 458.

[0075] According to some embodiments of this application, optionally, the PCB board placement compartment 500 is a semi-enclosed structure, consisting of a base and three movable clamping plates on the side of the baffles. The three baffles form a U-shaped structure, wherein the inner sides of the two opposing baffles are provided with slots for inserting the PCB board 459, and the upper part of the PCB board placement compartment 500 is provided with space for the gripping unit 403 to grip the PCB board 459.

[0076] Thus, the PCB board placement compartment 500 has a semi-enclosed structure, which facilitates the flat pulling of the PCB board 459. The slots on the inner sides of the two baffles separate the PCB board 459, which facilitates the gripping unit 403 to accurately grip a PCB board 459.

[0077] According to some embodiments of this application, optionally, the PCB board placement bin 500 and the robotic arm assembly 400 slide along the additional platform 200 on the follow-up storage table 300, and the robotic arm 402 cooperates with the gripping unit 403 to move the PCB board 459 relative to the processing station 101 between the PCB board placement bin 500 and the processing station 101.

[0078] In this way, the robotic arm 402 replaces manual labor, and only one robotic arm component 400 is needed to load and unload materials at all processing stations 101.

[0079] According to some embodiments of this application, optionally, the auxiliary platform 200 has a sliding track, and the follower storage platform 300 slides along the slide rail 202 on the auxiliary platform 200.

[0080] In this way, the robotic arm 402 is integrated with the PCB board placement compartment 500 and can move to different workstations via the slide rail 202. This allows multiple workstations to complete loading and unloading with just one robotic arm 402, resulting in a simple overall structure and reduced costs.

[0081] According to some embodiments of this application, optionally, the additional platform 200 is connected to the main body of the base 100 by bolts.

[0082] In this way, the distance between the auxiliary platform 200 and the base 100 will not be inconsistent or non-parallel due to external forces, which facilitates the disassembly and maintenance of the auxiliary platform 200.

[0083] According to some embodiments of this application, optionally, the additional platform 200 is mounted on the floor below by two legs 201.

[0084] This improves the stability of the add-on platform 200.

[0085] According to some embodiments of this application, optionally, the PCB drilling machine also includes a transport trolley, which includes a lifting platform and a clamping mechanism. The clamping mechanism is disposed on the lifting platform and is used for loading or unloading PCB boards into the placement bin 500.

[0086] In this way, the transportation mechanism can transport the PCB board placement bin 500 to the follow-up storage platform 300, or remove the PCB board placement bin 500 from the follow-up storage platform 300, thereby realizing automated loading and unloading of the PCB board placement bin 500.

[0087] Loading process: The robotic arm 402 drives the gripping unit 403 to hold the PCB board 459 to be processed, and then moves the PCB board 459 to be processed out of the bin and places it on a processing station 101 of the machine tool worktable. After the gripping unit 403 releases the workpiece, the robotic arm 402 drives the gripping unit 403 back to the top of the bin and takes down another PCB board 459 to be processed. Then the follow-up storage platform 300 moves one processing station 101 and the robotic arm 402 continues to place the PCB board 459 to be processed on the next processing station 101 of the machine tool worktable. This process continues until all six stations of the machine tool are filled with workpieces. The follow-up storage platform 300 drives the robotic arm 402 back to the initial position on the right, and the loading process ends.

[0088] Unloading process: After the PCB board 459 to be processed is completed, the robotic arm 402 moves the gripping unit 403 to the processing station 101 of the machine base 100 to pick up the processed part, and then sends the processed PCB board 459 to the front of the finished PCB board placement chamber 500. The finished PCB board 459 is then moved horizontally into the material slot of the finished PCB board placement chamber 500. The gripping unit 403 releases the finished part, and then moves one station with the moving storage platform. The robotic arm 402 continues to pick up the finished PCB board 459 from the next station of the processing station 101 of the machine base 100, and so on, until all the finished parts of the six stations of the machine tool are taken out and placed into the finished PCB board placement chamber 500. The moving storage platform 300 moves the robotic arm 402 back to the initial position on the right, and the unloading process ends.

[0089] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention.
