The arrangement of the sliding guide mechanism can improve the precision of the multistage telescoping mechanism 400 in the process of extension or contraction, and the phenomenon of blocking of the multistage telescoping mechanism 400 is avoided.

Optionally, the number of the sliding guide mechanisms disposed between the two expansion plates is two, the two sliding guide mechanisms are disposed side by side along the width direction of the expansion plates, and each sliding guide mechanism includes a pulley rail 407 and a plurality of pulleys 406 disposed at intervals, the pulleys being disposed to extend along the length direction of the expansion plates. Therefore, the precision of the multistage telescoping mechanism 400 in the process of extension or contraction can be further improved, and the situation that the telescopic plate is inclined to the left or inclined to the right in the telescoping process is avoided.

Further, as shown in fig. 4, two multi-stage telescoping mechanisms 400 are provided, and the two multi-stage telescoping mechanisms 400 are symmetrically arranged on two sides of the mounting frame 600. The blade battery clamping device further comprises a connecting beam 409, two ends of the connecting beam 409 are respectively connected with the two multistage telescopic mechanisms 400, the telescopic driving mechanism 100 is connected with one multistage telescopic mechanism 400 and used for driving the two multistage telescopic mechanisms 400 to synchronously extend and retract, and the bottom holding mechanism 500 is arranged between the two multistage telescopic mechanisms 400.

Alternatively, the number of the connecting beams 409 is set to be plural according to the number of the telescopic plates included in each multi-stage telescopic mechanism 400, so as to connect the correspondingly set telescopic plates, respectively. In this embodiment, three connecting beams 409 are provided, a first connecting beam 409 is connected to the bottom expansion plates 403 located at two sides of the mounting block 600, a second connecting beam 409 is connected to the middle expansion plates 402 located at two sides of the mounting block 600, and a third connecting beam 409 is connected to the top expansion plates 401 located at two sides of the mounting block 600. Alternatively, as shown in fig. 6 and 7, at least a portion of the connecting beams 409 may be nested when the multi-stage telescoping mechanism 400 is collapsed to improve compactness.

The rotation driving mechanism 800 is disposed on the bottom extension plate 403, one end of the bottom pocket mechanism 500 is in transmission connection with the driving end of the rotation driving mechanism 800, and the rotation driving mechanism 800 can drive the bottom pocket mechanism 500 to rotate around the first axis, so that the bottom pocket mechanism 500 has a bottom pocket state (a state shown in fig. 1-5) for holding the bottom end of the blade battery 700 and an avoidance state (a state shown in fig. 6 and 7) for avoiding the blade battery 700. Mechanism 500 switches between state and the state of dodging at the bottom of the pocket, can hold its bottom when centre gripping blade battery 700 to improve blade battery 700's centre gripping stability, also can dodge at non-centre gripping blade battery 700 and open other functional part, from not influencing blade battery 700 and carry out other processes, improve the use flexibility that this blade battery clamp got the device.

Specifically, the rotary drive mechanism 800 includes a swing cylinder. With continued reference to fig. 2 and 3, the pocket bottom mechanism 500 includes a pocket bottom plate 501, a first rocking bar 502 and a second rocking bar 505, the first rocking bar 502 and the second rocking bar 505 are respectively rotatably connected to the bottom ends of the two bottom expansion plates 403, the pocket bottom plate 501 is connected between the first rocking bar 502 and the second rocking bar 505, and the output end of the swing cylinder is in transmission connection with the first rocking bar 502 for driving the first winding bar to rotate around the first axis, so as to drive the pocket bottom plate 501 to rotate around the first axis. In this embodiment, the first axis is parallel to the length of the mount 600.

Optionally, the bottom pocket mechanism 500 further includes a flange bracket 503, and the swing cylinder is fixed on the bottom expansion plate 403 by the flange bracket 503. Further, the rotary drive mechanism 800 further includes a remote lever connecting shaft 504, and one end of the remote lever connecting shaft 504 is connected to a cylinder rod of the swing cylinder, and the other end is connected to the second rocker 505. Of course, two swing cylinders may be provided, two ends of the remote rod connecting shaft 504 are respectively connected to cylinder rods of the two swing cylinders, and the two swing cylinders synchronously drive the pocket bottom plate 501, the first rocker 502 and the second rocker 505 to rotate around the first axis, so as to reduce the requirement on the driving force of a single swing cylinder.

This device is got to blade battery clamp has following advantage:

1. support at the bottom of the pocket of the too big blade battery 700 of length can be satisfied to multistage telescopic machanism 400, and thereby can constantly superpose the expansion plate according to the demand and increase its length of body distance to support at the bottom of the pocket of the blade battery 700 of realization to different length, application range is wider.

2. The rodless cylinder is adopted to provide driving force for the multi-stage telescopic mechanism 400, so that space is saved, and the multi-stage telescopic mechanism is more convenient and stable.

3. Through ingenious structural design and spatial layout, before the device clamps and gets blade battery 700, bottom pocket mechanism 500 can contract in fixture 300's rear, does not influence its clamp and gets the action, and is convenient dexterous, can not influence the action requirement of blade battery 700 in process of production. After the centre gripping battery, can reach the bottom of the vertical direction of blade battery 700 through multistage flexible again, it is rotatory to drive bottom of the pocket mechanism 500 through rotary driving mechanism 800 to make bottom of the pocket mechanism 500 carry out the bottom of the pocket to blade battery 700, prevent that blade battery 700 from the fixture 300 landing when the production operation, stability and reliability when can guarantee the centre gripping of blade battery 700.
