Description

Technical Field

[0001] The utility model relates to the technical field of plate feeding, in particular to a servo feeding device with a correction function. Background Art

[0002] When stamping coils, they must be straightened by a straightening device before continuous stamping can proceed smoothly, thereby ensuring the quality of the stamped product. Conventional small stamping lines generally consist of three different devices: an unwinding device (to unwind the coil into sheets), a straightening device (to straighten the sheets), and a feeding device (to output the straightened sheets). After the coils are unwound into sheets, they are straightened during the conveying process and then transported to the stamping area by the feeding device for processing.

[0003] In the prior art, the Chinese utility model publication number CN219583600U discloses a servo feeding device, comprising a device body and a feeding mechanism, wherein the feeding mechanism is arranged on the device body. The utility model replaces manual operation by driving a roller with a servo motor, and manual operation only needs to be performed for loading, which has high work efficiency. When in use, the material is placed between the first roller and the second roller, and the second roller is driven by the servo motor to rotate to roll the material into shape. The formed material is then conveyed through the unloading mechanism. The utility model has a stable structure, is easy to use, has high work efficiency, and is highly practical.

[0004] However, the existing coil feeding device requires workers to place the plate on the conveyor belt, move the plate to the designated area through the conveyor belt, and then grab the plate by a mechanical gripper, and then place the plate in the stamping area for stamping processing. Since the plate is transported and placed at different angles on the conveyor belt, the position of the mechanical gripper when clamping it and placing it in the stamping area is offset, and the worker needs to adjust the position of the plate again, which reduces the efficiency of plate processing. Therefore, we need to propose a servo feeding device with a correction function. Utility Model Content

[0025] The limit assembly 8 includes a first cylinder 81 fixed to the top of the support frame 7. The telescopic end of the first cylinder 81 passes through the support frame 7 and is fixedly connected to a lifting plate 82. A limit plate 83 is welded to one end of the lower surface of the lifting plate 82. A limit switch 85 is provided on one side of the limit plate 83.

[0026] The correction assembly 9 includes a second cylinder 91 arranged on the support frame 7.

The stabilizing guide rods 93 improve the stability of the correction plate 92 during movement, avoid positional deviation of the correction plate 92, and thus avoid friction between the correction plate 92 and the vacuum belt 28.

[0028] A controller 10 is provided at the upper end of one side of the support frame 7, and the controller 10 is electrically connected to the first cylinder 81 and the second cylinder 91 respectively. A plurality of reinforcing blocks 84 are fixedly connected to the upper end of one side of the limit plate 83, and the upper surfaces of the plurality of reinforcing blocks 84 are bonded to the lower surface of the lifting plate 82. The plate is monitored by the photoelectric sensor 4 and a signal is sent to the controller 10, and then the controller 10 controls the first cylinder 81 to start to block the plate. At the same time, after contacting the limit switch 85, the second cylinder 91 is started to make the correction plate 92 close to the plate, and the position of the plate is straightened under the action of the correction roller 95.

[0029] The conveying mechanism 2 includes two groups of driving rollers 26 rotatably connected to the inner cavity of the mounting frame 1. Both groups of driving rollers 26 are transmission-connected to a vacuum belt 28. A plurality of through holes are provided on the upper surface of the vacuum belt 28. A plurality of supporting rollers 27 are provided in the inner cavity of the support frame 7, and the plurality of supporting rollers 27 are all provided in the inner cavity of the vacuum belt 28.

One end of the drainage square tube 6 is connected to the inner cavity of the mounting frame 1. A windproof plate 13 is fixedly connected to the inner cavity of the mounting frame 1. The exhaust fan 5 draws out the air in the vacuum belt 28 to form a negative pressure environment to facilitate the adsorption of the plate. At the same time, the vacuum belt 28 is blocked by the windproof plate 13 to facilitate the correction of it by the correction component 9.

[0033] When in use, start the drive motor 21 and the exhaust fan 5, place the plate on the vacuum belt 28, and the vacuum belt 28 transports the plate toward the baffle 11, so that the plate is transported stably under negative pressure. When it moves to the bottom of the photoelectric sensor 4, the photoelectric sensor 4 detects the plate and sends a signal to the controller 10 to control the first cylinder 81 to start, so that the limit plate 83 blocks the baffle 11. At the same time, the plate is located above the windbreak plate 13 to avoid adsorption of the plate. When the plate hits the limit plate 83, the limit switch 85 is triggered, and then the second cylinder 91 of the two sets of correction components 9 is controlled to start, so that the correction plate 92 approaches the plate, and the plate is corrected under the action of the correction roller 95. The first cylinder 81 and the second cylinder 91 are reset and the plate is moved to the side of the baffle 11 under the conveyance of the vacuum belt 28, so that the mechanical gripper can grab and transfer the plate, thereby improving the stamping efficiency of the plate.
