For fixture 600, not only can be rotatory along with connecting plate 400, can also realize the rotation for connecting plate 400, greatly increased the flexibility ratio. Moreover, the feeding and discharging device of the embodiment adopts a plurality of clamping mechanisms 600, so that the transfer of a plurality of battery cells can be realized, the feeding and discharging efficiency of the battery cells is greatly improved, and the production efficiency of the power battery can be improved.

Further, in this embodiment, the motion platform 100 can realize the linear movement of the fixing base 200 in three directions, so as to drive the clamping mechanism 600 to perform the linear movement in three directions.

More specifically, the motion platform 100 includes a first linear-motion mechanism 110, a second linear-motion mechanism 120, and a third linear-motion mechanism (not shown), the second linear-motion mechanism 120 is slidably disposed on the first linear-motion mechanism 110, and the first linear-motion mechanism 110 can drive the second linear-motion mechanism 120 to move along the first direction. The fixing base 200 is slidably disposed on the second linear moving mechanism 120, and the second linear moving mechanism 120 can drive the fixing base 200 to move along the second direction. The first linear-motion mechanism 110 is slidably disposed on a third linear-motion mechanism that can drive the first linear-motion mechanism 110 to move in a third direction. The first direction mentioned here is a Z-axis extending direction shown in fig. 1, that is, a vertical direction, the second direction is a Y-axis extending direction shown in fig. 1, and the third direction is an X-axis extending direction shown in fig. 1. It should be understood that, in the present embodiment, the first direction, the second direction and the third direction are perpendicular to each other two by two. Of course, in other embodiments, any one or two of the first linear-motion mechanism 110, the second linear-motion mechanism 120, and the third linear-motion mechanism may be selected according to the actual application.

Referring to fig. 1 and 3, the driving mechanism includes a driving member 310 and a first synchronizing wheel 320 in transmission connection with the driving member 310, the driving member 310 is fixed on the fixing base 200, and the first synchronizing wheel 320 is fixedly connected with the connecting plate 400. The rotating mechanism 500 includes a plurality of timing belts 510 and a plurality of second timing wheels 520, the plurality of second timing wheels 520 are disposed corresponding to the clamping mechanisms 600 one by one, the second timing wheels 520 are fixedly connected to the corresponding clamping mechanisms 600, and the timing belts 510 are wound around the first timing wheels 320 and the second timing wheels 520.

When the driving member 310 drives the first synchronizing wheel 320 to rotate, the connecting plate 400 can be driven to rotate together, so that the plurality of clamping mechanisms 600 can be driven to rotate together around the axis of the first synchronizing wheel 320. When the first sync wheel 320 rotates, the rotation is transmitted to each second sync wheel 520 through the sync belt 510, so that each second sync wheel 520 can drive the corresponding clamping mechanism 600 to rotate around the axis of the second sync wheel 520.

In the present embodiment, the types of the first synchronizing wheel 320 and the second synchronizing wheels 520 are the same, that is, the diameters of the first synchronizing wheel 320 and the second synchronizing wheels 520 are the same, so that the rotation angle of the clamping mechanism 600 is the same as the rotation angle of the connecting plate 400 around the axis of the first synchronizing wheel 320, and the clamping mechanism 600 is always in a horizontal state during the rotation process. Just so can guarantee that fixture 600 is also in the horizontality by the electric core of centre gripping to the in-process of preventing rotation, the position of electric core in fixture 600 changes, and then when avoiding the unloading, the not accurate problem of processing that leads to of the position of placing of electric core is not accurate enough.

More specifically, in the present embodiment, the second synchronizing wheels 520 are four in number and are arranged on the connection plate 400 at equal intervals. The first sync wheel 320 is located between two of the second sync wheels 520 and the other two second sync wheels 520. Also, the first sync wheel 320 is equally spaced from the two second sync wheels 520 disposed adjacent thereto. The arrangement can ensure the balance of the structure, and further ensure that the clamping mechanism 600 is always in a horizontal state in the rotating process.

It should be understood that, in other embodiments, the number of the second synchronizing wheels 520 may also be 2, 6, 8, and other even numbers, which are not limited herein.

The driving member 310 transmits the rotational motion to the first synchronous wheel 320 through the transmission assembly 700. In other embodiments, the transmission assembly 700 may be omitted, and the first synchronous wheel 320 may be directly driven to rotate by the driving member 310 through a coupling or the like.

As shown in fig. 3 and 4, the loading and unloading device further includes a preload member 810, and the preload member 810 abuts against the timing belt 510. Before the feeding and discharging device starts feeding, the pretensioning member 810 can be pressed against the timing belt 510 in advance by adjusting the pretensioning mechanism, so that the timing belt 510 is ensured to be in good contact with the first synchronizing wheel 320 and each second synchronizing wheel 520, and thus, each second synchronizing wheel 520 can rotate along with the first synchronizing wheel 320 while the first synchronizing wheel is ensured to rotate.

When the limiting member 820 moves from one end of the limiting hole 210 to the other end of the limiting hole 210, the connecting plate 400 rotates 90 °. As can be seen from fig. 4, the limiting hole 210 is an arc-shaped hole, and taking the figure as an observation perspective, when the limiting member 820 abuts against the left lower end of the limiting hole 210, the connecting plate 400 is in a horizontal state, and when the limiting member 820 abuts against the right upper end of the limiting hole 210, the connecting plate 400 is in a vertical state, that is, the state shown in fig. 3.

It should be noted that the loading and unloading device in the present embodiment is mainly used for loading and unloading the battery cell in the hot pressing process. After the moving platform 100 moves the clamping mechanism 600 to the designated material taking position, the clamping mechanism 600 is ready to take the material, and when the material is taken, the connecting plate 400 is in a horizontal state. After the cell is taken out by the clamping mechanism 600, the driving member 310 starts to drive the first synchronizing wheel 320 to rotate, so that the clamping mechanism 600 rotates and rotates around the axis of the first synchronizing wheel 320, until the connecting plate 400 rotates to a vertical state, the moving platform 100 moves the clamping mechanism 600 to a designated discharging position, and the clamping mechanism 600 releases the cell, so that the hot-pressing operation is performed on the cell by the hot-pressing mechanism.

The clamping mechanism 600 further comprises a pressing cylinder 630, and the pressing cylinder 630 is used for pressing the battery cell on the clamping jaw 620 so as to prevent the battery cell from being displaced. The two pressing cylinders 630 are respectively connected with the two clamping jaws 620. The adjustment of the pressing force of the battery cell can be realized by controlling the stroke of the piston of the pressing cylinder 630, so that the pressing force can be applied to battery cells of different models, and the battery cell can be prevented from being damaged due to overlarge pressing force. It will be appreciated that the hold down cylinder 630 may be omitted when the clamping force of the clamping jaw 620 on the cell is sufficient to avoid cell dislodgement.
