The carrier adopts a structure with an opening and closing function, the width of an opening for accommodating an operation object can be enlarged under the condition of passive stress, and the function of clamping the operation object can be realized once the external force disappears, so that the carrier has a clamping structure which is variable and can change the clamping state adaptively. Thus, the carrying device can carry out carrying operation on operation objects with different sizes.

Because the carrying plate on the carrier needs to be subjected to bending operation in the production process, a bending part obtained by bending the plate can generate a round angle, and the round angle part occupies the space vacated by the right-angle structure originally formed at the same angle. The bottom of the operation object of the object carrying device is usually provided with an edge with a right-angle structure, and only one side of the right-angle part of the operation object is contacted with the round angle of the bending part after the round angle is contacted with the bottom of the operation object, so that uneven stress of the operation object is caused, and the operation object is locally stressed too much to deform.

The surface of the main body carrying part 7 is a carrying surface 8 with a plane structure. The bending expansion part is provided with a deflection part 9 and a limit part 10, the limit part 10 is connected with the main body carrying part 7 through the deflection part 9, the deflection part 9 bends in the direction opposite to the direction of the carrying surface 8, the deflection part 9 has the function of deviating any one end of the limit part 10 from the plane of the carrying surface 8, and the deflection part 9 is connected with the limit part 10, so that the connection part of the deflection part 9 and the limit part 10 deviates from the plane of the carrying surface 8. The limiting part 10 is in vertical relation with the main body object carrying part 7, the surface of the limiting part 10 is provided with a limiting surface 11, and the limiting surface 11 is vertical to the object carrying surface 8.

The guided unit 4 is used for establishing a sliding connection relation between the carrier and the guide rail, so that the movement of the carrier can be limited through the guiding function of the guide rail. The guided unit 4 comprises four rollers, which are all mounted on the support block 6. Four gyro wheels are the matrix and distribute, and track 2 is located between two rows of gyro wheels, because be equipped with the recess on the gyro wheel, track 2's both sides are equipped with protruding structure, realizes the swing joint of carrier and track 2 in the recess of gyro wheel through the protruding structure embedding of track 2. The power input unit 5 is a magnet mounted on the support block 6 and located on one side of the guided unit 4, so that the power input unit 5 is adjacent to the magnetic levitation bench 1 at a small distance. The magnetic suspension workbench 1 is provided with energy output ends with magnetic field change, and the distribution structure of the energy output ends is consistent with that of the track 2. Therefore, the magnetic levitation workbench 1 can drive the power input unit 5 to move along the potential after energy is transmitted, and then drive the carrier to move.

The clamping unit comprises a drive plate 12, a clamping plate 13 and a return spring 14. The transmission plate 12 passes through the supporting block 6, and the transmission plate 12 is connected with the supporting block 6 in a sliding way. One end of the transmission plate 12 is positioned on one side of the support block 6, and the other end of the transmission plate 12 is positioned on the other side of the support block 6. The clamping plate 13 is a member formed by bending a plate material, and has a C-shaped cross section.
