Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

The existing battery string repairing system can not realize the automatic circulation and circulation of the material box, so that the material box needs to be loaded and unloaded frequently by manpower, and the repairing beat and the repairing efficiency of the battery string are influenced.

In view of this, the utility model provides a battery string material box circulation device, which realizes automatic circulation of material boxes among stations and greatly improves the repair efficiency of battery strings.

As shown in fig. 1 to 3, the battery string material box circulation device provided by the present invention includes a battery string feeding mechanism 1, an unqualified battery string material receiving mechanism 2, a qualified battery string material receiving mechanism 3, an empty material box stacking mechanism 4, and a full material box stacking mechanism 5. Wherein:

the battery string feeding mechanism 1 is used for supplying a material box filled with a battery string to be repaired and conveying an empty material box to be emptied to the unqualified battery string receiving mechanism 2.

The unqualified battery strings after being repaired are received into an empty material box on the unqualified battery string receiving mechanism 2, and the unqualified battery string receiving mechanism 2 is also used for conveying the empty material box to the qualified battery string receiving mechanism 3.

Qualified battery cluster after reprocessing is received to being located the empty charge box on qualified battery cluster receiving mechanism 3 in, qualified battery cluster receiving mechanism 3 still is used for carrying the full charge box of filling up qualified battery cluster to full charge box stacking mechanism 5 in to and carry empty charge box to empty charge box stacking mechanism 4 in.

The qualified battery string receiving mechanism 3 is also used for acquiring empty material boxes from the empty material box stacking mechanism 4 and conveying the empty material boxes to the unqualified battery string receiving mechanism 2.

The working process of the battery string material box circulation device provided by the utility model is as follows:

the battery string feeding mechanism 1 conveys the material box provided with the battery strings to be repaired to the material taking station of the battery strings to be repaired positioned on the material box.

When the to-be-repaired battery strings in the material boxes at the to-be-repaired battery string taking station are all taken away, the battery string feeding mechanism 1 conveys the emptied empty material boxes backwards to the unqualified battery string receiving mechanism 2.

The unqualified battery string receiving mechanism 2 conveys the empty material box to the NG material box taking station positioned on the unqualified battery string receiving mechanism, or directly conveys the empty material box backwards to the qualified battery string receiving mechanism 3. And the repaired unqualified battery strings are loaded into an empty material box positioned at the NG material box material taking station. And finally taking the NG material box filled with the unqualified battery pieces from the NG material box taking station by manual work or a box taking device.

The qualified battery string receiving mechanism 3 conveys the empty material boxes to the qualified battery string receiving stations on the qualified battery string receiving mechanism, or directly conveys the empty material boxes backwards to the empty material box stacking mechanism 4 continuously. And filling the repaired qualified battery strings into an empty material box positioned at a material receiving station of the qualified battery strings. After the material box is full, the qualified battery string receiving mechanism 3 conveys the full material box full of the qualified battery string to the full material box stacking mechanism 5.

It can be seen from the above process that the unqualified battery string receiving mechanism 2 and the qualified battery string receiving mechanism 3 need to use empty material boxes to respectively receive the unqualified battery strings and the qualified battery strings, when the material boxes in the battery string feeding mechanism 1 are all taken out, the battery string feeding mechanism 1 does not timely convey the empty material boxes backwards to the unqualified battery string receiving mechanism 2, and the unqualified battery string receiving mechanism 2 does not timely convey the empty material boxes backwards to the qualified battery string receiving mechanism 3, and the like, the empty material box shortage condition can occur on the unqualified battery string receiving mechanism 2 and the qualified battery string receiving mechanism 3.

At this time, the qualified battery string receiving mechanism 3 can be controlled to acquire empty material boxes from the empty material box stacking mechanism 4, and the acquired empty material boxes are directly conveyed to the qualified battery string receiving stations on the empty material box stacking mechanism, or the empty material boxes are conveyed to the unqualified battery string receiving mechanism 2, so that the empty material boxes of the qualified battery string receiving mechanism 3 and the unqualified battery string receiving mechanism 2 are supplemented, and long-time receiving waiting is prevented.

Therefore, the battery string material box circulation device provided by the utility model realizes automatic circulation of the material box among stations. In the repair process, only the material boxes filled with unqualified battery strings and qualified battery strings are taken away from the unqualified battery string receiving mechanism 2 and the full material box stacking mechanism 5 at regular intervals, the empty material boxes with the quantity exceeding the stacking quantity are taken away from the empty material box stacking mechanism at regular intervals, the material boxes filled with the battery strings to be repaired are supplemented to the battery string feeding mechanism 1 at regular intervals, the material feeding and the material discharging of the material boxes are not required to be carried out frequently, and finally the repair efficiency of the battery strings is greatly improved.

Optionally, as shown in fig. 4 to 6, the battery string feeding mechanism 1 includes a first magazine stacking rack 11, a magazine taking portion 12, a first magazine transferring portion 13, and a first lifting conveying portion 14, wherein: the feeding end of the first material box transferring part 13 is positioned below the first material box stacking rack 11, and the discharging end of the first material box transferring part 13 is positioned above the first lifting conveying part 14.

The material box provided with the battery string to be repaired is stacked in the first material box stacking frame 11, and the box taking part 12 is used for picking up the material box positioned at the lowest part of the first material box stacking frame 11 and placing the picked material box on the feeding end of the first material box transferring part 13.

First magazine transport portion 13 is used for transporting the magazine of the feed end of first magazine transport portion 13 to the unloading end of first magazine transport portion 13, and the unloading end of waiting to reprocess battery cluster in first magazine transport portion in the magazine is emptied. Namely, the blanking end of the first material box transferring part is the material taking station of the battery string to be repaired.

The first lifting conveying part 14 is used for lifting up empty material boxes which are positioned at the discharging end of the first material box transferring part 13 and are emptied, and conveying the empty material boxes backwards to the unqualified battery string receiving mechanism 2.

It can be seen that, through the cooperation of the first material box stacking rack 11, the box taking part 12, the first material box transferring part 13 and the first lifting conveying part 14, the battery string feeding mechanism 1 realizes automatic feeding of material boxes provided with battery strings to be repaired, and after the battery strings to be repaired in the material boxes are completely taken away, empty material boxes are conveyed backwards to the unqualified battery string receiving mechanism.
