[0032] This application proposes a material handling device, referring to... Figures 1 to 3The material handling device includes: two clamping mechanisms 10 arranged side by side along a first direction; a driving mechanism 20 for driving the clamping mechanisms 10 to move along the first direction to adjust the distance between the two clamping components 12; the clamping mechanism 10 includes a rotating component 11 disposed on the driving mechanism 20, and a clamping component 12 disposed at the rotating end of the rotating component 11. In this embodiment, the two clamping components 12 can clamp a workpiece respectively, and the workpiece can be driven to rotate around the clamping center by the rotating component 11 to adjust the posture of the workpiece. At the same time, the clamping mechanism 10 can be driven to move along the first direction by the driving component to adjust the distance between the two clamping components 12. It can adapt to workpieces of different sizes and avoid interference between the two clamping components 12 when clamping the workpiece.

[0033] Furthermore, the clamping center of the clamping assembly 12 is coaxial with the rotation center of the rotating end; the arrangement direction of the clamping mechanism 10 is perpendicular to the rotation center. The clamping assembly 12 and the rotating assembly 11 are concentrically arranged, which facilitates the adjustment of the workpiece phase and also facilitates coordinate calculation by the control system, reducing the amount of calculation. If the two are eccentrically arranged, the distance between the two clamping assemblies 12 can be adjusted by rotating the rotating assembly 11.

[0034] In some embodiments, the drive mechanism 20 can drive the two clamping mechanisms 10 to move closer or further apart simultaneously, or one of the clamping mechanisms 10 can be fixedly installed, and the drive mechanism 20 can drive the other clamping mechanism 10 to move along a first direction to adjust the distance between the two clamping mechanisms 10. Of course, the drive mechanism 20 described above can be driven by a cylinder, an electric cylinder, or other similar means.

[0035] Specifically, the drive mechanism 20 includes: a mounting frame 21 for mounting two clamping mechanisms 10; and a first drive member 22, disposed on the mounting frame 21, for driving one of the clamping mechanisms 10 to slide along a first direction. In this embodiment, one clamping mechanism 10 is fixedly mounted on the mounting frame 21, while the other clamping mechanism 10 is connected to the mounting frame 21 via a slide rail and a slider, enabling the clamping mechanism to slide along the first direction. The first drive mechanism 20 may be a pneumatic cylinder or an electric cylinder that is driven and connected to the other clamping mechanism 10.

[0036] Alternatively, the two clamping mechanisms 10 can be located on the same side of the mounting bracket 21, and the first driving member 22 can be located on the other side of the mounting bracket 21. This avoids interference between the movement of the first driving member 22 and the two clamping mechanisms 10. In addition, a through hole 23 can be provided on the mounting bracket 21. The driving mechanism 20 also includes a connector 24 located in the through hole 23, with one end of the connector 24 connected to one of the clamping mechanisms 10 and the other end connected to the driving end of the first driving member 22.

[0037] Since the electric cylinder can steplessly adjust the distance between the two clamping mechanisms 10, the material handling device in this embodiment can also be used in some specific application scenarios. For example, in some fixtures with multiple mounting positions, the distance between adjacent mounting positions is fixed. Therefore, when clamping workpieces, the aforementioned drive mechanism 20 can drive the two clamping mechanisms 10 to move, so that the distance between the two clamping centers matches the distance between the mounting positions, so that two workpieces on the clamping mechanism 10 can be installed into the corresponding mounting positions simultaneously. In addition, in cases where there are requirements for some mounting angles, the rotating component 11 can also drive the workpiece to rotate, so that its posture in the clamping mechanism 10 can be adapted to the fixture, further improving the assembly speed.

[0038] In some embodiments, the rotating assembly 11 includes: a base 111 disposed on the mounting frame 21; a rotating seat 112 rotatably connected to the base 111, wherein one end of the rotating seat 112 for mounting the clamping assembly 12 is a rotating end; and a second driving member 113 disposed on one side of the base 111 for driving the rotating seat 112 to rotate. In this embodiment, since one of the two clamping mechanisms 10 is fixedly mounted and the other is slidably mounted, one base 111 can be fixedly mounted on the mounting frame 21, and the other base 111 can be slidably mounted on the mounting frame 21. The aforementioned second driving mechanism 20 can be a stepper motor, which can be driven to rotate the rotating seat 112 via a gear set. Specifically, a ring rack can be provided around the outer periphery of the rotating seat 112, and a gear can be provided on the shaft of the stepper motor. The gear meshes with the ring rack to drive the rotating seat 112 to rotate. The stepper motor also has high rotational accuracy, which facilitates precise adjustment of the rotation angle of the workpiece.

[0039] Furthermore, the material handling device also includes a sensor 14 mounted on the base 111 and a probe 13 mounted on the rotating seat 112. The sensor 14 is located on one side of the rotation trajectory of the probe 13 and is used to sense the probe 13 to determine the rotation angle of the rotating seat 112. In this embodiment, the arrangement of the sensor 14 and the probe 13 can also be used for zero-reset detection of the rotating assembly 11, so that when the sensor 14 detects the probe 13, the phase of the rotating seat 112 is taken as the zero-reset phase.

[0040] In some embodiments, the clamping assembly 12 includes a clamping cylinder 121 and a jaw 122 disposed at the clamping end of the clamping cylinder 121. The clamping cylinder 121 includes at least three clamping ends, which are symmetrically arranged around the clamping center. In this embodiment, some workpieces may be circular plate-shaped workpieces or circular cap-shaped workpieces, and three-point clamping is more stable. In addition, the jaw 122 includes a connecting plate connected to the clamping end, and a clamping portion disposed at the end of the connecting plate away from the clamping center. The clamping portion can be used to clamp the outer periphery of the workpiece, and can also abut against the inner sidewall of the workpiece to achieve outward expansion clamping.

[0041] Furthermore, the material handling device also includes a robotic arm, with the mounting frame 21 located at the execution end of the robotic arm. The aforementioned material handling device can be driven by the robotic arm, which can move the material handling components within a certain working range to complete the workpiece transfer process. It is worth noting that an air passage can also be provided in the gripper 122, and air holes can be provided on the surface of the gripper 122 to assist in adsorbing the workpiece when gripping it. This embodiment incorporates a certain degree of redundancy design to prevent the workpiece from falling when the gripping components fail, thus improving the reliability of the material handling device.

[0042] This application also proposes a laser processing device, including a material handling device and a machine base, with the material handling device mounted on the machine base. This laser processing device can be a laser cutting machine, a laser marking machine, etc. In the embodiments of this application, the working principle of the material handling device is as follows: two clamping components 12 can each clamp a workpiece, and the workpiece is driven to rotate around the clamping center via a rotating component 11 to adjust the workpiece's posture. Simultaneously, the driving component can drive the clamping mechanism 10 to move along a first direction to adjust the distance between the two clamping components 12, thus adapting to workpieces of different sizes and preventing interference between the two clamping components 12 when clamping the workpiece.
