then, the driving motor 23 acts to drive the two endless chains 22 to rotate synchronously, so as to drive each carrier 50 to move towards the tail end of the rack 10, and in the moving process, when the mobile terminal is moved to a station needing to stay to complete the procedures of cleaning, reversing, drying and the like, the driving motor 23 stops acting, the positioning mechanism 30 and the opening and closing mechanism 40 at the corresponding station act in a matching way to press and fix the transmitted carrier 50 and release the clamping and fixing of the pressed and fixed carrier 50 on the clamped battery 200, each device at the corresponding station takes down the released battery 200, and after the corresponding operations of cleaning, reversing, drying and the like are completed, the battery 200 is put back on the carrier 50, and the carrier 50 then recovers the clamping and fixing of the battery 200;

finally, when the two endless chains 22 transfer the carriers 50 passed through the corresponding stations to the output station at the tail end of the rack 10, the battery 200 can be manually removed at this station, or the positioning mechanism 30 provided at the output station is matched with the opening and closing mechanism 40 to press and fix the passed carriers 50 and drive the fixed carriers 50 to open and close, so as to release the clamping and fixing of the battery 200, and the battery 200 can be removed manually or by a manipulator;

the above operations are repeated continuously to complete the automatic conveying, picking and placing of the battery 200, so as to complete the corresponding operations of cleaning, reversing, drying and the like. It should be noted that the conveying device 100 provided by the present invention can position and convey 4 tool carriers 50 and pick and place 4 batteries 200 at a time.

Compared with the prior art, the conveying device 100 provided by the utility model circularly conveys the carriers 50 on the annular conveying channel through the chain conveying mechanism 20, so that the carriers 50 sequentially pass through the positioning mechanism 30 and the opening and closing mechanism 40, the conveying is stable and accurate, and the carriers 50 are arranged at equal intervals, so that the carriers 50 can be simultaneously conveyed and accurately positioned among a plurality of stations, the adaptability of the whole conveying device is effectively improved, the conveying efficiency is high, the mechanism is simplified, the mounting and debugging space is saved, and the manufacturing cost is greatly reduced; in addition, the positioning mechanism 30 positions the carrier 50 by abutting against the opposite lower side end of the carrier 50 passing through, so that the opening and closing mechanism 40 drives the positioned carrier 50 to perform opening and closing actions to clamp and fix the battery 200 or release the clamping and fixing of the clamped battery 200, the carrier 50 does not move integrally, the positioning precision is further improved, and the battery 200 is convenient to operate, for example, the battery 200 is taken down from the carrier 50 to be matched with each device arranged at the side or the upper side of the rack 10 to complete corresponding operations such as cleaning, steering, drying, detecting or blanking, and the like.

The above disclosure is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the utility model, so that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the utility model.
