Description

Technical Field

[0001] This utility model relates to the field of mechanical gripper technology, and in particular to a linear motor-driven mechanical gripper for loading and unloading materials. Background Technology

[0002] A linear motor is an electric motor that directly converts electrical energy into linear motion without the mechanical transmission device required in traditional rotating electric motors. Its working principle is similar to "unfolding" the stator and rotor of a rotating electric motor into a linear form, generating direct thrust through electromagnetic interaction.

[0003] During transportation, linear motors are usually loaded and unloaded using mechanical grippers. However, linear motors are typically precision-structured and contain strong magnets, precision coils, and air gaps. The gripping force of traditional mechanical grippers is uncontrollable. When the mechanical gripper clamps the linear motor, it can easily cause excessive clamping force, damaging the coils, magnets, and sensors inside the linear motor, leading to damage during transportation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of damage to linear motors caused by the uncontrollable clamping force of traditional mechanical grippers in the prior art, and to propose a linear motor loading and unloading mechanical gripper.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A linear motor loading and unloading mechanical gripper includes a mounting plate. Two symmetrically arranged slide rails are fixedly mounted on the mounting plate. A mounting frame is slidably mounted on both slide rails. An electric telescopic rod is fixedly mounted on the mounting frame. A fixing plate is fixedly mounted at the bottom end of the electric telescopic rod. Four connecting columns are fixedly mounted at the bottom end of the fixing plate. A mounting platform is fixedly mounted at the bottom end of the four connecting columns. An air-bearing guide rail is fixedly mounted on the mounting platform. A sliding block is slidably mounted on the air-bearing guide rail, and a linear motor is fixedly mounted at the bottom end of the sliding block. A connecting rod is fixedly mounted at the bottom end of the sliding block. Moving frames are fixedly mounted at both ends of the connecting rod. A clamping mechanism for gripping the linear motor is provided within the moving frames.

[0006] Preferably, the mounting platform has a first sliding groove, the sliding block is slidably disposed in the first sliding groove, and the mounting platform also has a second sliding groove communicating with the first sliding groove, the connecting rod is slidably disposed in the second sliding groove.

[0007] Preferably, the clamping mechanism includes a bidirectional lead screw rotatably mounted in the movable frame, with nuts threaded onto both ends of the bidirectional lead screw, and mechanical grippers fixedly mounted on the outer walls of both nuts.

[0008] Preferably, both mechanical grippers are provided with rubber anti-slip pads, and a servo motor that drives a bidirectional lead screw to rotate is fixedly installed on the outer wall of the moving frame.

[0009] Preferably, a distance detection plate is fixedly installed on the mounting platform, and a laser detector is fixedly installed on the sliding block.

[0010] Preferably, the sliding block has a T-shaped structure, and the upper end of the sliding block is slidably disposed on the surface of the mounting platform.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model controls the sliding block to slide on the air-bearing guide rail by a linear motor, adjusts the distance between the two pairs of mechanical grippers, and uses a laser detector to monitor the distance between the two pairs of mechanical grippers in real time, thereby limiting the linear motor and preventing the mechanical grippers from applying excessive force to the linear motor, which could damage the linear motor.

[0012] 2. This utility model adjusts the distance between two mechanical grippers by rotating a bidirectional lead screw, so that the two mechanical grippers clamp the linear motor. In addition, the rubber anti-slip pad is attached to the linear motor to prevent the linear motor from slipping and being damaged after being clamped by the mechanical grippers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

A mounting platform 7 is fixedly mounted at the bottom of the four connecting columns 6. An air-bearing guide rail 8 is fixedly mounted on the mounting platform 7. A sliding block 9 is slidably mounted on the air-bearing guide rail 8. A linear motor 11 is fixedly mounted at the bottom of the sliding block 9. A connecting rod 15 is fixedly mounted at the bottom of the sliding block 9. Moving frames 16 are fixedly mounted at both ends of the connecting rod 15. A clamping mechanism for clamping the linear motor is provided inside the moving frame 16.

[0017] The mounting platform 7 has a first sliding groove 10, and the sliding block 9 is slidably disposed in the first sliding groove 10. The mounting platform 7 also has a second sliding groove 14 that is connected to the first sliding groove 10, and the connecting rod 15 is slidably disposed in the second sliding groove 14.

[0018] The clamping mechanism includes a bidirectional lead screw 17 rotatably mounted in the movable frame 16. Both ends of the bidirectional lead screw 17 are fitted with nuts by threads, and mechanical grippers 19 are fixedly mounted on the outer walls of the two nuts.

[0019] Both mechanical grippers 19 are equipped with rubber anti-slip pads 20 to increase the friction between the mechanical grippers 19 and the linear motor and prevent the linear motor from slipping off the mechanical grippers 19. A servo motor 18 that drives the bidirectional lead screw 17 to rotate is fixedly installed on the outer wall of the moving frame 16.

[0020] A distance detection plate 12 is fixedly installed on the mounting platform 7, and a laser detector 13 is fixedly installed on the sliding block 9.

The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0022] The functional principle of this utility model can be explained through the following operation methods: When in use, the device is used in conjunction with a conveyor belt to transport the linear motor, placing the linear motor directly below the mechanical gripper 19. The mounting platform 7 is lowered by the extension and retraction of the electric telescopic rod 4, driving the two mechanical grippers 19 to be positioned on both sides of the linear motor. The linear motor 11 precisely controls the sliding block 9 to slide on the air-bearing guide rail 8, adjusting the distance between the two moving frames 16 to limit the linear motor. The movement of the mechanical gripper 19 is monitored by the laser detector 13 to prevent damage to the linear motor. The servo motor 18 drives the bidirectional lead screw 17 to rotate, adjusting the distance between the two mechanical grippers 19 to grip the linear motor, and the rubber anti-slip pad 20 prevents the linear motor from slipping when being gripped.
