Description

A clamping mechanism, battery module flipping equipment and production system

Technical Field

The utility model belongs to the technical field of battery production and processing equipment, and in particular relates to a clamping claw mechanism, battery module turning equipment and a production system.

Background technique

The battery module is a battery component used to store and release electrical energy. Its weight is usually over 80 kg, which makes manual operation very difficult. In particular, when rotating the battery module manually to attach the base film, it is not only difficult to operate, but also easy to cause injuries. Therefore, a device for clamping the battery module to flip it is needed to reduce the workload of personnel and improve work efficiency.

The Chinese invention patent application with publication number CN 111469148 A discloses a battery module flipping device and a battery module production system. The battery module flipping device drives a lifting plate, a moving component and a clamping component to descend to a preset height through a lifting component, so that the first clamp component and the second clamp component are located at the height of the battery module to be clamped to wait for clamping the battery module. The moving component drives at least one of the first clamp component and the second clamp component to move so that the first clamp claw of the first clamp component and the second clamp claw of the second clamp component can cooperate to clamp the battery module. When the battery module is in a clamped state, the lifting component drives the battery module to rise to a spatial position where the battery module can be flipped, and the rotating component drives the first clamp claw to rotate. Since the battery module is in a clamped state at this time, the rotation of the first clamp claw will drive the battery module and the second clamp claw to rotate at the same time, so that the battery module can be flipped to a required angle.

Since the battery module is very heavy, the clamping mechanism of the above-mentioned flipping device cannot hold the battery module very firmly. Therefore, it is necessary to improve the clamping mechanism.
