Description

Technical Field

[0001] This utility model relates to the field of PCB processing equipment technology, and more specifically, it relates to an automated loading and unloading device for PCB boards. Background Technology

[0002] Printed circuit boards (PCBs) are providers of electrical connections for electronic components. Their design is mainly layout design. The main advantages of using PCBs are that they greatly reduce wiring and assembly errors, and improve automation and productivity.

[0003] In the current PCB manufacturing industry, some products require the installation of certain components inside the PCB board. Therefore, during the processing of the PCB board's shape, it is necessary to create grooves on the PCB board. Typically, depth-controlled routers are used to create these grooves.

[0004] In existing depth control milling equipment, it is usually necessary to manually push the trolley carrying the PCB board to be processed to the depth control milling equipment, and manually handle the PCB board for loading and unloading. This loading and unloading method increases labor costs and is prone to human operation errors, affecting the yield of PCB boards. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automated loading and unloading device for PCB boards to solve the above-mentioned technical problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automated loading and unloading device for PCB boards, comprising: a frame; a suction cup moving mechanism disposed on the frame; the suction cup moving mechanism having an output end; a panel adsorption mechanism disposed on the output end of the suction cup moving mechanism; and a table lifting mechanism disposed on the frame and below the panel adsorption mechanism.

[0007] Specifically, the trolley carrying the PCBs to be processed is pushed to the table lifting mechanism. The table lifting mechanism raises the table on the trolley, thus lifting the PCBs to the loading position. Then, the suction cup moving mechanism moves the panel adsorption mechanism, positioning it directly above the table lifting mechanism. The panel adsorption mechanism picks up the PCBs from the table lifting mechanism and, under the action of the suction cup moving mechanism, moves the PCBs onto the processing table of the depth-controlled router. After completing the depth-controlled router process on the PCBs, the suction cup moving mechanism moves the panel adsorption mechanism to pick up the PCBs and move them to the unloading position, thus completing the automatic loading and unloading of the PCBs.

[0008] By incorporating a table lifting mechanism, the tabletop used for transporting PCB boards on the material cart can be raised to within the movement range of the suction cup moving mechanism, thereby reducing the stroke of the suction cup moving mechanism. The position of the panel assembly adsorption mechanism is adjusted by the suction cup moving mechanism, which then adsorbs multiple stacks of PCB boards on the tabletop, placing them side-by-side on the worktable of the depth-controlled milling machine for assembly. This achieves automated PCB board loading and unloading operations, adapting to the processing needs of PCB boards of different specifications and quantities, effectively improving production efficiency and reducing errors caused by human factors.

[0009] Optionally, the platform lifting mechanism includes: a lifting linear module and a lifting assembly; the lifting linear module is mounted on the frame, and the lifting assembly is mounted at the output end of the lifting linear module.

[0010] Specifically, the lifting and moving linear module can be a motor-driven screw and nut assembly or a leverless cylinder; by setting the lifting component at the output end of the lifting and moving linear module, it can be driven by the lifting and moving linear module and contact the bottom surface of the moving table when it is necessary to lift the moving table, so that the moving table is separated from the material cart and lifted to the designated position.

[0011] Optionally, the lifting assembly includes: a connecting plate and a plurality of support plates; the connecting plate is disposed at the output end of the lifting linear module, and the plurality of support plates are evenly disposed at one end of the connecting plate away from the lifting linear module.

[0012] Specifically, at least two support plates are provided. Two support plates are respectively located at both ends of the connecting plate and on the outside of the material cart. The other support plates correspond one-to-one with the through slots on the material cart to prevent the support plates from being obstructed by the material cart when moving up and down. Several support plates are connected to the output end of the lifting and moving linear module through the connecting plate. When the lifting and moving linear module drives the connecting plate to move up, the connecting plate drives several support plates to move up, and the several support plates contact the bottom of the movable table and lift the movable table.

[0013] Optionally, the panel adsorption mechanism includes: a nozzle frame and a plurality of nozzles; the nozzle frame is disposed at the output end of the suction cup moving mechanism; the plurality of nozzles are evenly disposed on the nozzle frame.

[0014] Specifically, the suction nozzles are magnetic spring nozzles, which provide a certain degree of cushioning. Driven downwards by the suction cup moving mechanism, the nozzle holder makes contact with the PCB board, preventing a hard collision between the nozzle and the PCB. By setting multiple nozzles, their positions can correspond to the positions of the PCBs on the movable table, and two PCBs side-by-side on the movable table can be suctioned at once, accommodating the processing needs of PCBs of different sizes and quantities.

[0015] Optionally, the suction cup moving mechanism includes: a horizontal moving component and a vertical moving component; the horizontal moving component is disposed on the frame; the vertical moving component is disposed at the output end of the horizontal moving component; and the suction nozzle holder is disposed at the output end of the vertical moving component.

[0016] Specifically, the horizontal moving component moves the vertical moving component to directly above the table lifting mechanism. The vertical moving component then drives the suction nozzle holder downwards, bringing the suction nozzle into contact with and adsorbing the PCB board. The horizontal moving component then moves the vertical moving component onto the worktable of the deep-running machine, where the suction nozzle stops adsorbing, and the PCB board is placed on the worktable, thus completing the PCB board loading. After the PCB board processing is complete, the horizontal and vertical moving components drive the panel adsorption mechanism to pick up the PCB board and move it to the unloading table, thus completing the PCB board unloading.

[0017] Optionally, the horizontal movement component includes: a horizontal movement linear module and a connecting arm; the horizontal movement linear module is mounted on the frame; the connecting arm is mounted on the output end of the horizontal movement linear module; and the vertical movement component is mounted on the connecting arm.

[0018] Specifically, the horizontal linear module can be equipped with a corresponding rodless cylinder or lead screw assembly as needed. The horizontal linear module drives the connecting arm to move horizontally, which in turn drives the vertical moving assembly to move horizontally, thus moving the panel adsorption mechanism to the corresponding position for loading and unloading PCB boards.

[0019] Optionally, the vertical movement component includes: a lifting cylinder; the lifting cylinder is mounted on the connecting support arm, and the suction nozzle frame is mounted on the output end of the lifting cylinder; the suction nozzle frame is provided with a plurality of guide rods, the lifting cylinder is provided with a guide plate, and the guide plate is provided with a plurality of guide holes corresponding one-to-one with the plurality of guide rods, and the plurality of guide rods and the plurality of guide holes are slidably connected one-to-one.

[0020] Specifically, the nozzle frame is driven to move up and down by a lifting cylinder, and several guide rods on the nozzle frame slide within several guide holes on the guide plate to ensure the stability of the nozzle frame during movement.

[0021] Optionally, guide rails are provided on both sides of the frame below the table lifting mechanism.

[0022] Specifically, the guide rail can guide the direction of travel of the trolley, so that the PCB board on the moving platform of the trolley is adsorbed by the panel adsorption mechanism in a correct posture, ensuring the accurate alignment of the PCB board.

[0023] In summary, this utility model has the following beneficial effects: By setting a table lifting mechanism, the table used for transporting PCB boards on the material cart can be raised to the moving range of the suction cup moving mechanism, thereby reducing the stroke of the suction cup moving mechanism. By adjusting the position of the panel adsorption mechanism through the suction cup moving mechanism, the panel adsorption mechanism adsorbs multiple stacks of PCB boards on the table, placing them side-by-side on the worktable of the depth control milling machine for panel assembly. This achieves automatic loading and unloading of PCB boards, adapting to the processing needs of different specifications and quantities of PCB boards, effectively improving production efficiency and reducing errors caused by human factors.

[0032] Specifically, the trolley carrying the PCB board 7 to be processed is pushed to the table lifting mechanism 4. The table lifting mechanism 4 lifts the table on the trolley, thereby lifting the PCB board 7 to the loading position. Then, the suction cup moving mechanism 2 moves the panel adsorption mechanism 3, so that the panel adsorption mechanism 3 is directly above the table lifting mechanism 4. The panel adsorption mechanism 3 picks up the PCB board 7 from the table lifting mechanism 4 and moves the PCB board 7 to the processing table of the depth control router 8 under the action of the suction cup moving mechanism 2. After the depth control router process of the PCB board 7 is completed, the suction cup moving mechanism 2 moves the panel adsorption mechanism 3 to pick up the PCB board 7 and move the PCB board 7 to the unloading position, thus completing the automatic loading and unloading of the PCB board 7.

[0033] By setting up a table lifting mechanism 4, the table on the material cart 9 used for transporting PCB boards 7 can be raised to the moving range of the suction cup moving mechanism 2, thereby reducing the stroke of the suction cup moving mechanism 2. The position of the panel assembly adsorption mechanism 3 is adjusted by the suction cup moving mechanism 2. The panel assembly adsorption mechanism 3 adsorbs multiple stacks of PCB boards 7 on the table, placing them side-by-side on the worktable of the depth control milling machine 8 for assembly. This achieves automatic loading and unloading of PCB boards, adapting to the processing needs of different specifications and quantities of PCB boards, effectively improving production efficiency and reducing errors caused by human factors.

The other support plates 422 correspond one-to-one with the through slots on the material cart 9 to prevent the support plates 422 from being blocked by the material cart 9 when moving up and down.

The magnetic spring suction nozzle 32 can prevent the suction nozzle 32 from having a hard collision with the PCB board 7. By setting several suction nozzles 32, the position of the suction nozzle 32 can correspond to the position of the PCB board 7 on the movable table 10, and two PCB boards 7 side by side on the movable table 10 can be suctioned at the same time, which can meet the processing needs of PCB boards of different specifications and quantities.

Then, the horizontal moving component 21 moves the vertical moving component 22 to the worktable of the deep-running machine, the suction nozzle 32 stops adhering, and the PCB board 7 is placed on the worktable, thus completing the loading of the PCB board 7. After the processing of the PCB board 7 is completed, the horizontal moving component 21 and the vertical moving component 22 drive the panel adsorption mechanism 3 to pick up the PCB board 7 and move it to the unloading table, thus completing the unloading of the PCB board 7.
