[0003] In related technologies, the structure of the robotic arm is not reasonably arranged, and the grasping speed of the robotic arm is slow, which cannot meet the usage requirements of high-speed transfer devices. Summary of the Invention
[0004] This application aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0005] To this end, a first aspect of this application proposes a robot.
[0006] A second aspect of this application proposes a robot component.
[0007] In view of this, a first aspect of this application proposes a robot, including: a first linear motor, the first linear motor including a stator and a plurality of movers that move linearly relative to the stator in a first direction; at least one set of mechanical hands, each set of mechanical hands including two arm components, the two arm components being respectively connected to two movers; in each set of mechanical hands, the two arm components move towards each other or away from each other.
[0008] A robot provided by this application includes a first linear motor and at least one set of mechanical hands, and each set of mechanical hands includes two arm components. The arm components are used to grasp workpieces.
[0009] The first linear motor includes a stator and a plurality of movers, each mover cooperating with the stator, and the mover being able to move linearly relative to the stator in the first direction. Each arm component cooperates with a mover. So that the mover drives the arm component to move under the action of the stator, that is, the mover can drive the workpiece grasped by the arm component to move. The first linear motor can effectively drive the grasped workpiece to move linearly at high speed and with high precision, and can realize the high-speed movement of transporting the workpiece, which is beneficial to improving the working cycle and working efficiency of the robot.
[0010] In addition, the number of arm components is multiple. Therefore, at least a part of the multiple arm components can be made to work according to the specific actual usage situation. In this way, it is beneficial to improve the working cycle and working efficiency of the robot.
[0011] It can be understood that the first linear motor includes a stator and a plurality of movers. The plurality of movers are all cooperated with the stator. It can also be said that the plurality of movers share one stator. In this way, while meeting the usage requirements of driving a plurality of arm components to move by a plurality of movers, the material input of the stator is reduced. In this way, it is beneficial to reduce the production cost of the robot, and is beneficial to reducing the overall size of the first linear motor, and further beneficial to reducing the overall size of the robot, improving the usage performance and market competitiveness of the product.
[0012] Further, the two arm components are respectively connected to the two movers, that is, each arm component is connected to one mover. In each group of manipulators, the two arm components move towards each other or away from each other. In this way, when the two arm components of each group of manipulators move simultaneously, the impact forces caused by the high-speed or decelerated movement of the two movers connected to the two arm components will cancel each other out, so that each mover can drive an arm component to perform a faster moving operation, and can maintain the stability of the entire motion system, reduce the shaking amount when the robot is working, and is beneficial to improving the accuracy and reliability of handling workpieces.
[0013] According to the above-mentioned robot of the present application, the following additional technical features may also be provided:
[0014] In some embodiments, optionally, one of the stator and the mover includes a magnet, and the other includes a coil.
[0015] In this embodiment, the structure of the first linear motor is further defined such that one of the stator of the first linear motor and the mover of the first linear motor includes a magnet, and the other includes a coil. The stator of the first linear motor includes a magnet, and the mover of the first linear motor includes a coil. Or the stator of the first linear motor includes a coil, and the mover of the first linear motor includes a magnet.

However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.
[0094] The following refers to Figures 1 to 3 Robot 10 and robot assembly 60 according to some embodiments of the present application.
[0095] As Figure 1 And Figure 2 As shown, a robot 10 according to some embodiments of the present application includes: a first linear motor 100, the first linear motor 100 including a stator 110 and a plurality of rotors 120 that move linearly in a first direction relative to the stator 110; at least one group of manipulators 1100, each group of manipulators 1100 including two arm assemblies 200, the two arm assemblies 200 being respectively connected to the two rotors 120; in each group of manipulators 1100, the two arm assemblies 200 move towards each other or away from each other.
[0096] A robot 10 provided by the present application includes a first linear motor 100 and at least one group of manipulators 1100, and each group of manipulators 1100 includes two arm assemblies 200. The arm assembly 200 is used to grasp workpieces.

Each arm assembly 200 cooperates with a mover 120. So that the mover 120 drives the arm assembly 200 to move under the action of the stator 110, that is, the mover 120 can drive the workpiece grasped by the arm assembly 200 to move. The first linear motor 100 can effectively drive the grasped workpiece to move along a straight line at high speed and high precision, and can realize high-speed movement of the workpiece, which is conducive to improving the working rhythm and work efficiency of the robot 10.

[0196] The material of the support plate 300 includes light plates such as carbon fiber and aluminum plates to reduce the mass of the moving parts and improve the movement speed. The swing arm 210 includes a second motor 212 and a speed reducer. The second motor 212 includes a servo motor or a torque motor. The robotic arm 220 is made of lightweight and high-strength materials. For example, the robotic arm 220 includes a carbon fiber robotic arm or an aluminum robotic arm.
[0197] As Figure 1 and Figure 3 shown, the lifting axis J3 includes a lead screw 242, a third motor 244, and a coupling 246. Through a linear guide rail 800, the rotational motion can be converted into a linear motion to achieve the linear lifting motion of the swing arm 210, the robotic arm 220, and the end effector 230.
[0198] The lifting shaft J3 and the linear guide 800 are both installed on the support plate 300, and the nut of the lead screw 242 and the swing arm 210 are both connected to the slider 310 of the guide rail. In this way, when the third motor 244 (such as, a rotary motor) of the J3 axis works, through the conversion of the linear guide 800, the swing arm 210, the robotic arm 220 and the end effector 230 will perform up and down lifting movements. The fixed installation of the lifting shaft J3 on the support plate 300 can ensure the stability and reliability of the operation of the swing arm 210, the robotic arm 220 and the end effector 230. At the same time, the component structure is optimized, which is conducive to installation and maintenance.

[0203] The robot 10 of the present application is combined with an industrial camera to achieve efficient and stable wafer handling.
[0204] The robot 10 of the present application can replace many complex handling structures, realizing the simplification of the structure and efficient operation.
[0205] The first arm assembly 200a and the second arm assembly 200b can share the stator 110 and the grating scale of the first linear motor 100, and greatly improve the working rhythm. Therefore, the structure is more reasonable and the cost is lower.
[0206] The first arm assembly 200a and the second arm assembly 200b perform counter-movements (such as, mirror movements), which will effectively reduce the impact force of the movement of the first arm assembly 200a and the second arm assembly 200b, reduce the movement instability caused by high acceleration and deceleration, and improve the working efficiency of the equipment, which is conducive to realizing the miniaturization and light weight of the equipment.
[0207] The swing arm 210 is installed on the support plate 300.
[0208] The robot 10 of the present application includes a drive controller 400 (the drive controller 400 includes a driver and a controller), and the vacuum pipeline and the lubricating oil pipeline are arranged inside the arm assembly 200.
[0209] The robot 10 of the present application is an integrated drive and control unit, with a high degree of automation of the product.
[0210] The robot 10 of the present application can be used in combination with an industrial camera.
[0211] The robot 10 of the present application uses a vacuum chuck to pick up, place, and transport workpieces.
[0212] The robot 10 of the present application includes a wireless power supply unit 500.
