[0031] Embodiment 1

[0032] This embodiment provides a fully automatic handling device for square shell battery modules, including a support plate 10. An installation plate 20 is arranged below the support plate 10. A servo motor 22 and a bidirectional lead screw 27 are arranged on the installation plate 20. The servo motor 22 is connected to the bidirectional lead screw 27. Electric grippers 31 are arranged at both ends below the installation plate 20. The electric grippers 31 are connected to the bidirectional lead screw 27.

[0033] The support plate 10 is provided with a connection hole (not shown in the figure). The connection hole is circular. The connection hole is used to connect an industrial robot or an automated device. The handling device is moved above the square shell module by the industrial robot or the automated device. The handling device moves downward under the control of the industrial robot or the automated device, clamps the square shell module, and then carries it.

[0034] The support plate 10 is connected to the installation plate 20 through a connecting rod 11. The support plate 10 and the installation plate 20 have the same shape and size. One end of the connecting rod 11 is connected to the periphery of the support plate 10 by threads, and the other end is connected to the installation plate 20 by threads. This is set to leave a space between the support plate 10 and the installation plate 20, so that the servo motor 22 and the bidirectional lead screw 27 can be arranged on the upper surface of the installation plate 20.

[0035] The installation plate 20 fixes the servo motor 22 on the upper surface of the installation plate 20 through a motor mounting plate 21. Shaft support seats 26 are fixed at both ends of the installation plate 20 along the length direction. The bidirectional lead screw 27 is fixed on the shaft support seats 26. One end of the motor synchronous pulley 23 of the servo motor 22 and one end of the lead screw synchronous pulley 25 of the bidirectional lead screw 27 are on the same side and are connected by a synchronous belt 24. Lead screw nuts 28 are arranged on both sides of the bidirectional lead screw 27. The lead screw nuts 28 pass through the installation plate 20. The installation plate 20 is correspondingly provided with moving holes (not shown in the figure) for the translation of the lead screw nuts 28. When the servo motor 22 rotates, the motor synchronous pulley 23 drives the synchronous belt 24 to rotate. The synchronous belt 24 drives the lead screw synchronous pulley 25 to rotate. The lead screw synchronous pulley 25 drives the bidirectional lead screw 27 to rotate. The rotation of the bidirectional lead screw 27 drives the lead screw nuts 28 to slide horizontally.

[0036] The lower surface of the mounting plate 20 is provided with guide rails 29, and the guide rails 29 are fixed on both sides of the mounting plate 20 along the length direction. The two ends of the guide rails 29 on both sides are respectively connected to the electric grippers 31. An installation block 30 is arranged in the middle of the electric grippers 31, and the installation block 30 is connected to the lead screw nut 28. By connecting the electric grippers 31 with the lead screw nut 28 through the installation block 30, the electric grippers 31 are connected to the guide rails 29 and the lead screw nut 28 on the same horizontal line, so that the electric grippers 31 can be stably installed under the mounting plate 20 and move stably. By arranging the guide rails 29 on the lower surface of the mounting plate 20, the lead screw nut 28 drives the electric grippers 31 at both ends to move along the length direction of the square shell module 40 more smoothly and quickly. The electric grippers 31 at both ends under the mounting plate 20 can move towards or away from each other along the guide rails 29.

[0037] Insulating blocks 32 are arranged on both sides of the bottom of the electric grippers 31 along the width direction of the square shell module 40. Corresponding bidirectional channels (not marked in the figure) are arranged at the bottom of the electric grippers 31. The two sides of the insulating blocks 32 are fixedly connected to the electric grippers 31 through the bidirectional channels. The insulating blocks 32 are connected to the module pull rod 33, and the module pull rod 33 is fixed at the center of the insulating blocks 32. The insulating blocks 32 can move along the bidirectional channels, and the insulating blocks 32 on both sides move towards or away from each other along the bidirectional channels at the same time, driving the module pull rod 33 to move along the width direction of the square shell module.

[0038] The fully automatic square shell battery module handling device of this embodiment controls the movement of the bidirectional lead screw 27 through the servo motor 22. The bidirectional lead screw 27 drives the electric grippers 31 on both sides to move in the length direction of the square shell module 40, and can clamp square shell modules 40 with different lengths. By controlling the insulating blocks 32 to move in the width direction of the square shell module 40 through the electric grippers 31, square shell modules 40 with different widths can be clamped, so as to realize the handling of square shell modules 40 with different widths and different lengths.

[0039] The working principle of this embodiment:

[0040] This embodiment is connected to the industrial robot through the connection holes of the support plate 10. During use, the industrial robot moves the fully automatic square shell battery module handling device above the square shell module 40 to be handled, and then moves the fully automatic square shell battery module handling device downward until the module pull rod 33 is inserted into the installation hole of the square shell module 40. At this time, under the control of the servo motor 22 and the electric grippers 31, the module pull rod 33 clamps the end plates of the square shell module 40 in the width and length directions of the square shell module 40 respectively. Finally, the industrial robot lifts the fully automatic square shell battery module handling device and the square shell module 40 and transports them to the designated position.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
