Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing technology, and in particular to a six-axis dual-station board take-up machine. Background Technology

[0002] After a PCB board is manufactured, if it has some minor defects in appearance or does not conform to the original specifications, it is called an NG (Not Found) product. To distinguish NG products from normal products, during the product inspection process, normal products and NG products are respectively affixed with normal QR codes and NG product QR codes. The NG product QR code stores the reason for the NG status. When distinguishing products later, scanning the QR code can determine whether the product is an NG product. Existing board receiving machines are all single-station machines. Existing board receiving machines do not have a temporary storage station for NG products, so NG products are ultimately transported to the next production line via conveyor belt just like normal products. Utility Model Content

[0003] The purpose of this utility model is to provide a six-axis dual-station plate receiving machine, which aims to solve the technical problem that there is no temporary storage station for NG products in the existing technology.

[0004] To achieve the above objectives, this utility model provides a six-axis dual-station plate receiving machine, including a frame and a feeding belt, a plate receiving section, and a robot arm disposed within the frame. A plate-retrieving window is provided on one side of the frame. The feeding belt is equipped with a positioning section and a scanning section for lifting and lowering. The positioning section is used to position the plate, and the scanning section is used to scan the plate. The plate receiving section includes an NG position and at least two carrier positions. Each carrier position is equipped with a transport vehicle, and each transport vehicle holds a receiving rack. The NG position is equipped with a mounting bracket and a receiving platform. The mounting bracket has several slots, one side of which has an insertion port, and the other side has a plate-retrieving port corresponding to the plate-retrieving window. A driving section is provided on the top surface of the receiving platform, and a fork is driven and connected to the driving section. A lifting cylinder is provided on the bottom surface of the receiving platform, and the lifting cylinder is used to drive the driving section to move up and down.

[0005] Preferably, the frame is equipped with a lift for driving the insert to move up and down.

[0006] Preferably, the lifting platform includes a lifting motor, a screw, and a guide rod. The lifting motor drives the screw to rotate. The screw is threadedly connected to one side of the bracket, and the guide rod is slidably connected to one side of the bracket.

[0007] Preferably, each of the slots consists of several horizontally arranged combination rods.

[0008] Preferably, the drive unit includes a mounting platform and a drive motor, a ball screw, and a guide rail disposed on the mounting platform. The ball screw is used to drive the forks, and the guide rail is slidably connected to the bottom of the forks.

[0009] Preferably, the bottom of the drive unit extends downward with a plurality of sliding rods, and the receiving platform is provided with sliding holes that are slidably connected to each of the sliding rods respectively. Limiting rods are connected between each of the sliding rods to achieve limiting cooperation with the bottom surface of the receiving platform.

[0010] Preferably, a first positioning plate and a second positioning plate are respectively provided at the beginning and end of the feeding belt. Both the first positioning plate and the second positioning plate are provided with a number of clearance positions to achieve clearance coordination with the robot arm.

[0011] Preferably, a lifting cylinder is provided at the bottom of the feed belt, and the lifting cylinder is used to realize the lifting and lowering of the first positioning plate.

[0012] The above-mentioned technical solutions of the six-axis dual-station plate take-up machine provided in this embodiment of the utility model have at least one of the following technical effects:

[0013] During operation, boards are transported into the frame via a feed belt. The scanning unit scans the boards, and the positioning unit positions them. A trolley carrying a storage rack is pushed into the carrier position of the frame. After scanning, the correct boards are identified by the scanning unit, and a robotic arm picks them up from the feed belt and places them on the storage rack. When the scanning unit identifies incorrect boards, the robotic arm picks them up from the feed belt and places them on the forks in the NG (Not Found) position. A lifting cylinder lifts the drive unit, which in turn drives the forks to insert the boards through the slots. When the rack is full, the rack's retrieval window opens, allowing NG boards from each slot to be retrieved. This system is convenient for collecting and retrieving NG boards during the board collection process, better distinguishing between correct and NG boards, and improving sorting speed and production efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, such as Figures 1-8 As shown, a six-axis dual-station plate receiving machine is provided, including a frame 1 and a feeding belt 2, a plate receiving section, and a robot arm 3 disposed within the frame 1. A plate picking window 11 is provided on one side of the frame 1. The feeding belt 2 is equipped with a positioning section 21 and a scanning section 22 for lifting and lowering. The positioning section 21 is used to position the plate, and the scanning section 22 is used to scan the plate. The plate receiving section includes an NG position 4 and at least two carrier positions 41. Each carrier position 41 is provided with a transport vehicle 42, and a receiving rack 43 is placed on each transport vehicle 42. The NG position 4 is provided with a insertion rack 5 and a receiving platform 6. The insertion rack 5 is provided with a plurality of slots 51. One side of each slot 51 is provided with an insertion port, and the other side is provided with a plate picking port corresponding to the plate picking window 11. The top surface of the receiving platform 6 is provided with a driving section, and the driving section is driven and connected to a fork 61. The bottom surface of the receiving platform 6 is provided with a lifting cylinder 62, which is used to drive the driving section to move up and down.

[0029] Furthermore, the frame 1 is equipped with a lifting mechanism 7 for driving the insertion rack 5 to move up and down. The lifting mechanism 7 includes a lifting motor 71, a screw 72, and a guide rod 73. The lifting motor 71 drives the screw 72 to rotate. The screw 72 is threadedly connected to one side of the insertion rack 5, and the guide rod 73 is slidably connected to one side of the insertion rack 5. Specifically, when the robot arm 3 inserts the NG board into the slot 51, the robot arm 3 clamps the board on the feed belt 2 and places it on the fork 61 of the NG position 4. The lifting cylinder 62 lifts the drive unit to a suitable height. The drive unit drives the fork 61 to insert the board through the insertion port of the slot 51. The lifting motor 71 drives the screw 72 to rotate, thereby moving the insertion rack 5 downward so that the next slot 51 can receive the NG board, achieving precise control of the height of the insertion rack 5.

[0030] Furthermore, each slot 51 is composed of several horizontally arranged combination rods 52. Specifically, each slot 51 has several combination rods 52 on its bottom surface, and the top surfaces of each combination rod 52 combine to form a receiving surface for receiving the NG plate, thereby reducing the contact area between the receiving surface and the NG plate. At the same time, the fork 61 can be configured to be composed of at least two strip plates that extend in the same direction as each combination rod 52, and the width of the strip plate is smaller than the distance between two adjacent combination rods 52. Meanwhile, a clearance cavity is formed between two adjacent combination rods 52. When the fork 61 inserts the NG plate into the slot 51 through the insertion port of the slot 51, the two strip plates that make up the fork 61 can cooperate with the clearance cavity in the corresponding position to achieve a good clearance effect.

[0031] Furthermore, the drive unit includes a mounting platform 64 and a drive motor 641, a ball screw 642, and a guide rail 643 disposed on the mounting platform 64. The ball screw 642 is used to drive the forks 61, and the guide rail 643 is slidably connected to the bottom of the forks 61. A plurality of sliding rods 644 extend downward from the bottom of the drive unit. The receiving platform 6 is provided with sliding holes 645 that are slidably connected to each of the sliding rods 644. Limiting rods 646 are connected between each of the sliding rods 644 to achieve limiting cooperation with the bottom surface of the receiving platform 6. Specifically, when the scanning unit 22 scans the board and identifies it as an incorrect board, the robot arm 3 picks up the board from the feed belt 2 and places it on the fork 61 of the NG position 4. The lifting cylinder 62 lifts the mounting platform 64, and at the same time drives the slide rod 644 to slide upward in the sliding hole 645. The lifting height of the mounting platform 64 can be limited by setting a limit plate. The drive motor 641 drives the fork 61 to move closer to the insert 5 through the ball screw 642 to achieve the storage effect.

[0032] Furthermore, a first positioning plate 23 and a second positioning plate 24 are respectively provided at both ends of the feeding belt 2. Both the first positioning plate 23 and the second positioning plate 24 are provided with a plurality of clearance positions 25 for cooperating with the robot arm 3 to avoid clearance. A lifting cylinder 26 is provided at the bottom of the feeding belt 2, which is used to realize the lifting and lowering of the first positioning plate 23. Specifically, the feed belt 2 has several drive rods arranged front to back, and two fixed frames are symmetrically arranged at the bottom of the feed belt 2. Each fixed frame is equipped with a lateral drive component and a clapper component. The lateral drive component is used to realize the lateral movement of the clapper component. The fixed frame is also equipped with a cylinder, and the output shaft of the cylinder is connected to a lifting platform. Several crossbeams are arranged front to back on the lifting platform, and several push rods are provided on the crossbeams. There are clearance positions 25 between each crossbeam and between each push rod. Each clearance position 25 corresponds to a gripper. Each push rod is equipped with a pulley at the top to realize the lateral movement of the plate. After the plate enters the feed belt 2, the plate is transported by the feed belt 2. The plate is fed to the end and abuts against the second positioning plate 24. When the size of the plate is large, the first positioning plate 23 is raised by the lifting cylinder 26 and is higher than the top surface of the feed belt 2, so that the other side of the plate abuts against the first positioning plate 23. The left and right sides of the plate are pushed by the humming drive to achieve left and right positioning. When the robot arm 3 grips the plate of the feed belt 2, the gripper part of the robot arm 3 cooperates with the clearance position 25 on the first positioning plate 23 and the second positioning plate 24 to avoid interference between the gripper part of the robot arm 3 and the first positioning plate 23 and the second positioning plate 24, so as to achieve a good clamping effect.

[0033] Working principle: During use, the board is transported into the frame 1 via the feed belt 2. The scanning unit 22 scans the board and positions it via the positioning unit 21. The carrier 42, carrying the storage rack 43, is then pushed into the carrier position 41 of the frame 1. The scanning unit 22 is a CCD camera. After scanning the board, the scanning unit 22 identifies it as the correct board. The robotic arm 3 then picks up the board from the feed belt 2 and places it on the storage rack 43. When the scanning unit 22 scans the board... When a board is identified as incorrect, the robot arm 3 picks up the board from the feed belt 2 and places it on the fork 61 of the NG position 4. The lifting cylinder 62 lifts the drive unit, and the drive unit drives the fork 61 to insert the board through the slot 51. When the insertion rack 5 is full, the board retrieval window 11 of the frame 1 is opened, and the NG boards in each slot 51 of the insertion rack 5 are taken out through the board retrieval port. This makes the operation convenient and facilitates the collection and removal of NG boards during the board collection process.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
