Description

Technical Field

[0001] This utility model relates to components for industrial automation robots, and in particular to a dual-station flipping mechanism for industrial robots. Background Technology

[0002] In industrial automated production lines, most parts require multiple processing steps from raw material to finished product. The processing reference surface often needs to be changed between semi-finished parts to complete the processing of the workpiece. After each processing step is completed, a flipping mechanism must be added to the production line. A robotic arm or robot picks up the workpiece from the machine tool and flips the workpiece processing reference surface on a flipping table outside the machine tool. This process greatly increases the cycle time of the production line, resulting in a significant reduction in production efficiency.

[0003] Therefore, it is necessary to design a dual-station flipping mechanism for industrial robots to solve the above problems. Utility Model Content

[0028] (Example 1)

[0029] See Figures 1 to 4 This embodiment of an industrial robot dual-station flipping mechanism includes a base 1; one end of the base 1 is fixed with a first flipping gripping device 2, and the other end is movably provided with a second flipping gripping device 3 that can approach or move away from the first flipping gripping device 2; the first flipping gripping device 2 and the second flipping gripping device 3 cooperate to transport the workpiece to the workstation.

[0030] Furthermore, the base 1 is provided with a slide rail 4; the second flipping gripping device 3 is slidably connected to the slide rail 4 via a slider 5; the base 1 is provided with a drive device 6 for driving the second flipping gripping device 3 to move closer to or away from the first flipping gripping device 2. This design allows the second flipping gripping device 3 to be flexibly adjusted according to the size and type of the workpiece, improving the versatility of the equipment.

[0031] More specifically, the driving device 6 includes a driving cylinder; the driving cylinder is fixed inside the base 1, and the piston rod of the driving cylinder is fixedly connected to the second flipping gripping device 3. The movement of the second flipping gripping device 3 is realized by the extension and retraction movement of the driving cylinder, which is simple to operate and responds quickly.

[0032] Furthermore, both the first flipping gripper 2 and the second flipping gripper 3 include a mounting base 7 and a swing cylinder 8 fixed on the mounting base 7; a gripper assembly 9 is fixed on the rotating end of the swing cylinder 8; the mounting base 7 of the first flipping gripper 2 is fixedly connected to the base 1; the mounting base 7 of the second flipping gripper 3 is fixedly connected to the slider 5 through a connecting plate. The swing cylinder 8 drives the gripper assembly 9 from the vertical direction to the horizontal direction, so that the two gripper assemblies 9 can be arranged opposite each other to exchange workpieces, realizing the rapid and accurate flipping and conveying of workpieces.

[0033] To further optimize the equipment structure, the base 1 is formed by a bottom plate and side plates surrounding the bottom plate; the first flipping gripping device 2 is fixed to the side plates; the second flipping gripping device 3 is slidably connected to the long side plates. Meanwhile, to prevent dust and debris from damaging the internal components of the equipment, a corrugated dust cover 10 is provided on the base 1, avoiding the first flipping gripping device 2 and the second flipping gripping device 3.

[0034] To improve workpiece clamping stability and gripping efficiency, the gripper assembly 9 is preferably a pneumatic three-jaw gripper. The pneumatic three-jaw gripper features a standardized design, facilitates maintenance and replacement, and is suitable for handling workpieces of various shapes and sizes.

[0035] To meet the processing requirements of different workpieces, the base 1 is equipped with an adjustment mechanism 11 for adjusting the stroke of the second flipping gripping device 3; several adjustment slots are evenly distributed along the length of the side wall of the base 1; the adjustment mechanism 11 can be installed in any of the limiting slots. The adjustment mechanism 11 includes an adjustment block 111 and a limiting screw 112 threadedly connected to the adjustment block 111. By adjusting the position of the limiting screw 112, the stroke of the second flipping gripping device 3 can be precisely adjusted.

[0036] To ensure the safety of the second flip gripping device 3 when it reaches its designated position, a sensor block 12 for detecting the position of the second flip gripping device 3 is provided at the end of the base 1 away from the first flip gripping device 2. Simultaneously, the second flip gripping device 3 is provided with a limiting block 13 corresponding to the sensor block 12; a buffer 14 and a pressure sensor 15 are installed on the limiting block 13, further improving the safety and reliability of the equipment.

[0037] The working principle of this embodiment is as follows: When loading is required, the gripper assembly 9 in the first flip gripper 2 opens its gripper, and the robot loads the workpiece. The gripper assembly 9 of the first flip gripper 2 closes to grip the workpiece, and the swing cylinder 8 of the first flip gripper 2 drives the gripper assembly 9 to rotate 90 degrees. At the same time, the gripper assembly 9 in the second flip gripper 3 opens, and the swing cylinder of the second flip gripper 3 drives the gripper assembly 9 to rotate 90 degrees. The center lines of the two gripper assemblies 9 are on the same straight line. Then, the drive cylinder drives the second flip gripper 3 to move towards the first flip gripper 2. After the drive cylinder 6 is in place, the gripper assembly 9 in the second flip gripper 3 closes to grip the workpiece, and the gripper assembly 9 of the first flip gripper 2 opens. Then, the drive cylinder 6 pushes the second flip gripper 3 back to its original position. Finally, the swing cylinder 8 of the second flip gripper 3 rotates the gripper assembly 9 in the opposite direction by 90 degrees, completing the loading process.
