Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, and more specifically, to a material feeding device for a plate feeder. Background Technology

[0002] The board feeding and unloading process is a crucial link in automated production lines, referring to the process of automatically supplying and removing boards using specialized equipment. During loading, the board feeding machine moves the boards to be processed from the rack to the processing position; unloading is the reverse, efficiently removing the finished boards and stacking them neatly. This achieves seamless connection between processes, significantly improving production cycle time and continuity, effectively reducing manual intervention, and ensuring board surface cleanliness and operational safety.

[0003] Currently widely used vacuum suction cup type plate feeders have shortcomings. Their suction cup layout is usually fixed and cannot be flexibly adapted to different plate sizes and shapes. When processing plates that are too large or too small, especially those with irregular shapes, the fixed suction cup positions may lead to insufficient adsorption area and uneven force, resulting in unstable adsorption, plate shifting, slipping, or even damage during transport. This not only directly affects the stability and efficiency of production, but also restricts the flexibility and overall efficiency of the production line because it cannot adapt to the rapid changeover requirements of multi-variety, small-batch plate production in flexible manufacturing. Therefore, a loading and unloading device for plate feeders is needed. Utility Model Content

[0018] Please see Figures 1-4 A loading and unloading device for a plate feeder includes a frame 1, a traveling assembly, a lifting assembly, and a gripping assembly. The traveling assembly is located at the top of the frame 1 and includes a base 15, a drive motor 16, and drive wheels 17. The base 15 is slidably mounted on the top of the frame 1, the drive motor 16 is fixedly mounted on the upper surface of the base 15, and the drive wheels 17 are fixedly mounted on the output shaft of the drive motor 16. Slide tracks are provided on both sides of the top of the frame 1, and the drive wheels 17 roll in cooperation with the slide tracks. This allows the entire device to move stably along the frame 1, realizing the conveying of plates between different workstations.

[0019] The lifting assembly is installed on the bottom side of the walking assembly and includes telescopic cylinders 18. Both telescopic cylinders 18 are fixedly installed on the lower end face of the base 15, and a top plate 19 is fixedly installed on the top of the gripping frame 2. The telescopic ends of the telescopic cylinders 18 are fixedly connected to the top plate 19. This enables the entire gripping assembly to move vertically, thus accurately lowering the suction cup 4 to the material position for gripping or raising it to a safe height for transfer.

[0020] The gripping assembly is installed at the bottom of the lifting assembly and includes a gripping frame 2, connecting pipes 3, suction cups 4, a vacuum pump 5, an extraction pipe 6, and connecting components. Multiple equally spaced connecting pipes 3 are slidably installed on the inner bottom side of the gripping frame 2, and multiple suction cups 4 are evenly fixedly installed at the bottom end of each connecting pipe 3. A vacuum pump 5 is fixedly installed on one side of the gripping frame 2, and an extraction pipe 6 is fixedly connected to the output end of the vacuum pump 5. Retractable connecting components are provided between the extraction pipe 6 and each of the multiple connecting pipes 3. This constitutes a negative pressure adsorption system, which can generate a vacuum through the vacuum pump 5, allowing the suction cups 4 to reliably adsorb the material.

[0021] The connecting assembly includes a first connector 7, a telescopic tube 8, and a second connector 9. The first connector 7 is fixedly installed on the side wall of the suction pipe 6 and is rotatably and sealingly connected to the telescopic tube 8; the end of the connecting pipe 3 is rotatably and sealingly connected to the second connector 9, and the other end of the telescopic tube 8 is fixedly connected to the second connector 9. Meanwhile, a fixing frame 10 is fixedly installed on the gripping frame 2, and the suction pipe 6 passes through the fixing frame 10, with the two forming a limiting fit. This connecting assembly ensures that the vacuum pipeline can flexibly extend, retract, and steer when the connecting pipe 3 moves, while the fixing frame 10 provides stable support, ensuring the continuity and sealing reliability of the vacuum adsorption.

[0022] To adjust the suction cup layout, a motor 11 is fixedly installed on the side wall of the gripping frame 2, and a bidirectional screw 12 is fixedly connected to the output shaft of the motor 11. The bidirectional screw 12 is divided into two sections with opposite thread directions. A drive plate 13 is fixedly installed on the upper end face of the connecting tube 3, and the drive plate 13 is threadedly connected to the bidirectional screw 12. In addition, limit guide rods 14 are fixedly installed on both sides of the inside of the gripping frame 2, and the two ends of the drive plate 13 are slidably connected to the limit guide rods 14 respectively. This allows the drive plates 13 and the connecting tube 3 on both sides to move towards or away from each other when the motor 11 drives the bidirectional screw 12 to rotate, thereby flexibly adjusting the spacing distribution of the suction cups 4. The limit guide rods 14 ensure the stability and straightness of the connecting tube 3 during movement and prevent deflection.

[0023] In summary, during operation, the entire equipment works as follows: Telescopic cylinder 18 is activated, driving the gripping frame 2 to move vertically downwards until all suction cups 4 are in stable contact with the surface of the material to be transported. Then, vacuum pump 5 is activated, creating a negative pressure inside each suction cup 4 through a closed vacuum passage composed of suction pipe 6, first connector 7, telescopic pipe 8, second connector 9, and connecting pipe 3, thus uniformly and firmly adsorbing the material. After confirming stable adsorption, telescopic cylinder 18 reverses its movement, driving the gripping frame 2 to rise smoothly and safely lift the material away from its original position. Next, drive motor 16 is activated, controlling the drive wheel 17 to roll within the slide rail at the top of frame 1, driving base 15, telescopic cylinder 18, and the entire gripping assembly to move horizontally along a predetermined trajectory until the material is accurately transported to the next target position. Upon arrival, telescopic cylinder 18 extends again, driving the gripping frame 2 to slowly descend with the material. Once the material is in complete contact with the target position's table surface, vacuum pump 5 stops working and releases the vacuum, the suction cups 4 release their adsorption, and the material is precisely placed in the designated position, completing one complete loading and unloading cycle.

[0024] When different sizes of boards need to be processed during production, the device can quickly adjust the layout of the suction cups 4 to adapt to the changes: starting the motor 11 drives the bidirectional screw 12 to rotate. Since the threads at both ends are opposite, it can synchronously drive the drive plates 13 on both sides that are threaded with it to move in opposite directions along the limiting guide rod 14, thereby adjusting the spacing of all connecting pipes 3 and flexibly changing the distribution range of the suction cups 4. During the entire adjustment process, the telescopic pipes 8 connecting each connecting pipe 3 will automatically expand and contract accordingly as the connecting pipes 3 move. The sealed rotational connection between the first joint 7 and the second joint 9 effectively compensates for the angle change of the pipeline, ensuring the continuity and sealing reliability of the vacuum pipeline during the dynamic adjustment process. This ensures that the working efficiency of the vacuum pump 5 is not affected by the change in the position of the suction cups 4, guarantees the stability of the adsorption force under different layouts, and greatly improves the adaptability of the equipment to different specifications of boards and the flexibility of production.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
