Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending equipment technology, and in particular to a robotic sheet metal bending reversing device. Background Technology

[0002] With the increasing development of industrial automation, bending technology in the sheet metal industry is also constantly evolving. Initially, sheet metal bending was mostly achieved by manually operating bending machines. However, due to the passage of time and product changes, sheet metal bending has become more diversified and varied, leading to increased demands on sheet metal bending. As a result, robotic automated bending has gradually replaced manual bending to meet market needs. However, robotic bending has a drawback: the issue of sheet metal reversal when bending diverse sheet metal. Because sheet metal varies in shape and size during bending, reversal is inconvenient, requiring the robotic arm to re-clamp the sheet metal, making bending extremely difficult. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a robot sheet metal bending and reversing device with simple structure and convenient sheet metal bending and reversing.

[0004] To achieve the above objectives, the present invention provides a robotic sheet metal bending and reversing device, comprising a fixed frame mounted on a robotic arm, a first clamping rod horizontally fixed at one end of the fixed frame, a second clamping rod slidably mounted at the other end of the fixed frame, a clamping device for clamping sheet metal between the first clamping rod and the second clamping rod, and a sliding device for driving the second clamping rod to slide on the fixed frame.

[0005] A further improvement is that the clamping device includes several L-shaped connecting blocks, one end of which is provided with a suction cup for holding the sheet metal, and the other end of which is provided on the first clamping rod or the second clamping rod.

[0006] A further improvement is that the sliding device includes a sliding rail, which is mounted on a fixed frame. A sliding plate is slidably mounted on the sliding rail. The second clamping rod is mounted on the sliding plate. The fixed frame is provided with a sliding device for driving the sliding plate to slide.

[0007] A further improvement is that the sliding device includes a gear rack, which is mounted on a fixed frame. A servo motor is mounted on the sliding plate, and a gear is mounted on the shaft of the servo motor. The gear meshes with the gear rack for transmission.

[0008] A further improvement is that: the first clamping rod and the second clamping rod are respectively provided with sliding channels, and a number of sliding blocks are provided in the sliding channels with matching connecting blocks. The connecting blocks are locked to the sliding blocks by bolts, and the bolts pass through the sliding blocks and abut against the inner wall of the sliding channels to restrict the sliding of the sliding blocks.

[0009] A further improvement is that the fixing frame is equipped with a fixing plate, which is bolted to the robotic arm.

[0010] The advantages and beneficial effects of this utility model are as follows:

[0011] With a simple structure, it facilitates sheet metal bending and reversing. By adjusting the distance between the first and second clamping rods, it can adapt to different sizes and widths of sheet metal to be bent, thus enabling the clamping of sheet metal of different sizes, followed by flipping or reversing. The operation is simple and highly automated, avoiding the need to re-clamp the sheet metal clamping device. This not only facilitates operation and clamping but also greatly improves production efficiency. Attached Figure Description

[0013] Figure 2 This is a partial structural diagram of a robot sheet metal bending and reversing device according to an embodiment of the present invention. Detailed Implementation

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0015] like Figures 1-2 As shown, a robot sheet metal bending and reversing device includes a fixed frame 1 mounted on a robotic arm. A first clamping rod 3 is horizontally fixed at one end of the fixed frame 1, and a second clamping rod 4 is slidably mounted at the other end of the fixed frame 1. A clamping device for clamping sheet metal is provided between the first clamping rod 3 and the second clamping rod 4. A sliding rail 9 is bolted to the fixed frame 1, and a sliding plate 91 is slidably mounted on the sliding rail 9. One end of the second clamping rod 4 is fixed to the sliding plate 91. A gear rack 8 is fixed to the fixed frame 1, and a servo motor 7 is mounted on the sliding plate 91. A gear is mounted on the shaft of the servo motor 7, and the gear meshes with the gear rack 8 for transmission.

[0016] Specifically, the clamping device includes a plurality of L-shaped connecting blocks 5. One end of each connecting block 5 is provided with a suction cup 6 for holding the sheet metal. The suction cups 6 are evenly distributed on the first clamping rod 3 and the second clamping rod 4, so that the sheet metal can be evenly forcefully held when it is clamped. The other end of the connecting block 5 is provided on the first clamping rod 3 or the second clamping rod 4.

[0017] To accommodate different sheet metal sizes, the first clamping rod 3 and the second clamping rod are each provided with a sliding channel. A matching connecting block 5 and a sliding block 11 are located within each sliding channel. The connecting block 5 is locked to the sliding block 11 by bolts 10. The bolts 10 pass through the sliding block 11 and abut against the inner wall of the sliding channel, thus restricting the sliding block 11 from sliding. When adjusting the distance at which the suction cups 6 pick up the sheet metal, simply push the sliding block 11 to the predetermined position, then tighten the bolts to position the sliding block 11, thereby adjusting the distance between the suction cups 6. This allows for the accommodating of sheet metal of different sizes, enabling better suction and clamping of the sheet metal, thus improving the effectiveness, firmness, and safety of the clamping.

[0018] In order to facilitate the connection between the fixed frame 1 and the robot arm, the fixed frame 1 is provided with a fixed plate 2, which is locked to the robot arm by bolts.

[0019] Working principle:

[0020] The mounting bracket 1 is locked onto the robotic arm, and the distance between the suction cups 6 is adjusted. At this point, based on the sheet metal's dimensions, the servo motor 7 operates, driving the gears and gear rack 8 to mesh and transmit power. This causes the sliding plate 91 to slide on the sliding rail 9, adjusting the distance between the first clamping rod 3 and the second clamping rod 4 to fit the sheet metal. The suction cups 6 on the first and second clamping rods 3 and 4 then adhere to the sheet metal, and the robotic arm inserts it into the equipment for bending. After bending, the sheet metal's shape changes, altering the clamping distance. The servo motor 7 then operates, driving the second clamping rod 4 to slide, adjusting the distance between the first and second clamping rods 3 and 4 again, thus changing the clamping distance. The suction cups 6 then adhere to the sheet metal again, and the robotic arm can remove the bent sheet metal for flipping and further bending. By adjusting the distance between the first clamping rod 3 and the second clamping rod 4, it can adapt to different sizes and widths of sheet metal being bent, thus enabling the clamping of sheet metal of different sizes, followed by flipping or reversing. The operation is simple and highly automated, avoiding the need to re-clamp the sheet metal clamping device. This not only facilitates operation and clamping but also greatly improves production efficiency.
