Description

Technical Field

[0001] This utility model relates to the field of PCB depaneling machine technology, and in particular to an automatic loading and unloading mechanism for a PCB depaneling machine. Background Technology

[0002] Printed circuit boards (PCBs) are one of the core components of electronic devices and are widely used in the electronics manufacturing industry. In the PCB manufacturing process, the depaneling process is a crucial step, separating the PCBs, which are formed continuously during production, into individual, qualified products according to design requirements. The depaneling machine, as the core equipment for this process, directly affects the overall production progress and processing quality of the PCBs. However, existing PCB depaneling machines generally suffer from the following problems: During the operation of a PCB depaneling machine, operators must first move the continuous PCB boards onto the machine's tray. After the cutter completes the separation, the individual PCB boards are manually removed from the machine and transferred to the next process. This manual loading and unloading method not only increases the labor intensity of operators but also results in low machine efficiency. Therefore, we propose an automatic loading and unloading mechanism for PCB depaneling machines. Utility Model Content

[0006] Preferably, the worktable is internally rotatably connected to a bidirectional lead screw, and the circumferential surface of the bidirectional lead screw is threaded with two symmetrically distributed limiting plates. A servo motor is fixedly assembled inside the worktable, and the output end of the servo motor is fixedly connected to the bidirectional lead screw, and the servo motor is electrically connected to the controller.

[0007] Preferably, a support plate is fixedly mounted on the surface of the limiting plate, the bottom of the support plate is slidably connected to the upper surface of the workbench, and the height of the support plate is the same as the height of the limiting plate.

[0008] Preferably, a fourth electric actuator is fixedly mounted on the upper surface of the tray, and a pressure plate is fixedly mounted on the output end of the fourth electric actuator.

[0012] Compared with the prior art, this utility model provides an automatic loading and unloading mechanism for a PCB board depaneling machine, which has the following beneficial effects: (1) Through the coordinated operation of the second electric push rod, the top plate, the third electric push rod, and the push plate, this utility model can automatically lift the stacked PCB boards to the appropriate height and accurately push them onto the surface of the pallet.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] like Figures 1-5As shown, this utility model provides an automatic loading and unloading mechanism for a PCB board depaneling machine, including a worktable 1. A mounting bracket 2 is fixed to the upper surface of the worktable 1. A first electric push rod 3 is horizontally fixed to the surface of the mounting bracket 2, and its output end is rigidly connected to a sliding frame 4. The sliding frame 4 and the mounting bracket 2 are slidably adapted via guide rails, ensuring that the sliding frame 4 moves only in the vertical direction. A cutter 5 is detachably mounted on the lower surface of the sliding frame 4 using bolts, facilitating later maintenance and replacement. A controller 6 is fixed to the side wall of the mounting bracket 2. The controller 6 serves as the central hub of the entire mechanism, electrically connected to all electric actuators to achieve coordinated action control.

[0019] A tray 7 is fixed on the workbench 1 directly below the cutter 5 to support the stacked PCB boards to be separated. A second electric push rod 8 is vertically fixed to the lower surface of the mounting bracket 2, with its output end extending upward and fixing a top plate 9. The side wall of the top plate 9 fits against the edge of the tray 7, and the top plate 9 can vertically lift the stacked PCB boards. A guide plate 10 is fixed on one side of the workbench 1, located below the tray 7, to receive individual PCB boards after separation and transfer them to the next process.

[0020] A fixed plate 14 is fixed on the side of the upper surface of the workbench 1 away from the guide plate 10. A clamping plate 15 is slidably fitted on the surface of the fixed plate 14, and the clamping plate 15 can slide horizontally along the fixed plate 14. A sliding plate 11 is vertically fixed on the upper surface of the clamping plate 15. A third electric actuator 12 is horizontally fixed on the surface of the sliding plate 11, with its output end facing the support plate 7 and a push plate 13 fixed thereon. A connecting plate 17 is vertically fixed on the surface of the push plate 13. The connecting plate 17 slides through the sliding plate 11 to form a guide structure to prevent the push plate 13 from tilting when it moves.

[0021] The worktable 1 is internally connected to a bidirectional lead screw 18 with symmetrical reverse threads on its circumference, and is threaded to two limit plates 19. A servo motor 20 is fixed inside the worktable 1, and its output end is coaxially fixed with the bidirectional lead screw 18. A support plate 21 is vertically fixed to the surface of the limit plate 19. The support plate 21 slides and adapts to the upper surface of the worktable 1 to ensure that the limit plate 19 moves smoothly.

[0022] In the above scheme, the two limiting plates 19 move synchronously towards or away from each other to adapt to PCB boards of different widths. Since PCB boards of different specifications also differ in length, to accommodate the stroke of the third electric actuator 12, this embodiment also fixes a positioning plate 16 on the upper surface of the worktable 1 near the clamping plate 15. The upper vertical cross-section of the positioning plate 16 is a right-angled triangle. A vertically sliding insert plate 24 is provided inside the clamping plate 15, adapting to the inclined surface of the positioning plate 16. A spring 25 is sleeved on the surface of the insert plate 24, and the lower end of the spring 25 is fixed to the clamping plate 15, achieving unidirectional positioning of the clamping plate 15. By adjusting the position of the clamping plate 15 on the fixing plate 14, PCB boards of different lengths can be adapted. In addition, since the PCB boards need to be stacked on the top plate 9, and the top plate 9 has high limiting plates 19 on both sides, if personnel want to place the PCB boards on the top plate 9, they need to raise the PCB boards above the top of the limiting plates 19. At this time, the space enclosed by the two limiting plates 19 and the sliding plate 11 is equivalent to a box. If personnel want to place the PCB boards in the box, they need to lift them up to a certain height. In order to make it easier for personnel to place the PCB boards on the top plate 9, the clamping plate 15 slides on the fixing plate 14 and can form a one-way positioning, which can not only meet the adaptation of different PCB boards, but also reduce the labor of personnel to place the PCB boards.

[0023] A fourth electric push rod 22 is vertically fixed on the upper surface of the tray 7. Its output end extends upward and fixes the pressure plate 23, which can press the PCB board to be separated onto the surface of the tray 7.

[0024] The specific working principle is as follows: The operator pulls the insert plate 24 upwards, causing its bottom to disengage from the positioning plate 16, and removes the clamping plate 15 from the fixing plate 14, providing sufficient space for the stacking of PCB boards. Then, the operator neatly stacks the connected PCB boards on the upper surface of the top plate 9. According to the width of the PCB board to be separated, the controller 6 starts the servo motor 20. The output shaft of the servo motor 20 drives the bidirectional lead screw 18 to rotate clockwise or counterclockwise. The bidirectional lead screw 18 drives the two limit plates 19 to slide towards or in opposite directions along the upper surface of the worktable 1 through the reverse thread. The support plate 21 slides synchronously with the limit plates 19 to ensure that the limit plates 19 move smoothly. When the inner sidewalls of the two limit plates 19 are respectively in contact with the two side edges of the PCB board, the servo motor 20 stops, completing the lateral positioning of the PCB board.

[0025] Insert the card plate 15 again from the end of the fixing plate 14 and slide it toward the tray 7 to a suitable position, which should ensure that the third electric push rod 12 can fully push the PCB board onto the tray 7 within its stroke range. Then, send a command through the controller 6 to start the second electric push rod 8. The output end of the second electric push rod 8 slowly extends upward, driving the top plate 9 and the stacked PCB boards to rise synchronously. When the upper surface of the topmost PCB board is flush with the lower surface of the push plate 13, the controller 6 controls the second electric push rod 8 to stop moving, completing the height calibration before loading.

[0026] After the height calibration is completed, the controller 6 starts the third electric push rod 12. The output end of the third electric push rod 12 extends horizontally towards the tray 7, driving the push plate 13 to move synchronously. The push plate 13 separates the topmost PCB board from the stacked state and smoothly pushes it onto the upper surface of the tray 7. After pushing it into place, the output end of the third electric push rod 12 retracts, driving the push plate 13 to reset, completing a single automatic feeding.

[0027] Next, controller 6 activates the fourth electric push rod 22. The output end of the fourth electric push rod 22 moves downward, causing the pressure plate 23 to move downward synchronously until the lower surface of the pressure plate 23 is in close contact with the upper surface of the PCB board, pressing the PCB board firmly onto the support plate 7 to prevent displacement during separation. After the PCB board is positioned and fixed, controller 6 activates the first electric push rod 3. The output end of the first electric push rod 3 pushes the sliding frame 4 downward. The sliding frame 4 moves vertically downward along the guide rail of the mounting frame 2, causing the cutter 5 to move synchronously. The cutter 5 continues to move downward, contacting the PCB board on the support plate 7 and applying cutting force, dividing the continuous PCB board into individual PCB boards according to the preset trajectory. After cutting, controller 6 controls the output end of the first electric push rod 3 to retract, causing the sliding frame 4 and the cutter 5 to return to their initial positions. Under the action of gravity, the individual PCB boards fall from the surface of the support plate 7 into the guide plate 10 below. The guide plate 10, through its own tilting structure or built-in conveying components, stably guides and transfers the individual PCB boards to the material frame or conveyor line of the next process, completing the automatic unloading.
