Description

Technical Field

[0001] The present application relates to the technical field of battery production, and in particular to a conveying tray for a battery production line. Background Art

[0002] Power batteries are generally produced in a multi-station assembly line. Existing multi-station assembly lines usually use conveyor trays to carry power batteries, so that the power batteries can be moved between multiple stations through the conveyor trays.

[0003] The existing conveyor pallet includes a chassis and a clamping assembly. A clearance groove is provided on the bottom plate. The clamping assembly includes a bidirectional screw, two clamping plates and a rotating motor. The bidirectional screw is arranged in the clearance groove along the length direction of the clearance groove and is rotatably connected to the groove wall of the clearance groove. Each threaded segment of the bidirectional screw is screwed with a clamping plate. The driving shaft of the rotating motor is connected to the bidirectional screw so that the two clamping plates can be driven to move closer or farther from each other by the rotating motor to drive the bidirectional screw to rotate, thereby pressing the power battery between the two clamping plates. A self-locking structure is also provided in the rotating motor so that the driving shaft of the rotating motor can be locked by the self-locking mechanism to maintain the two clamping plates in a state of clamping the power battery.

[0004] However, since the conveyor tray needs to move and stop constantly when driving the power battery to switch stations, and the power batteries are generally heavy, the self-locking structure will bear a large load every time it stops and accelerates, and is easily damaged.

[0005] In view of this, it is necessary to provide a conveying tray for a battery production line. Utility Model Content

[0037] When it is necessary to clamp and fix the power battery, the user can drive the pair of driven screws 211 to rotate by controlling a pair of driving motors to drive the two clamping seats 212 to synchronously approach the center of the tray 1, so that the power battery can be clamped by the clamping seats 212. At this time, the ratchet 31 on each driven screw 211 will not be stuck by the corresponding locking rod 32; after the power battery is clamped by the clamping seat 212, the elastic member 333 will drive the locking rod 32 to insert between the ratchet teeth of the ratchet 31, and limit the driven screw 211 from driving the clamping seat 212 away from the center of the tray 1. The driven screw 211 can be rotated in the direction of locking and sharing the load borne by the self-locking mechanism in the drive motor, thereby reducing the risk of damage to the drive motor; when the power battery needs to be removed from the conveying tray 1 of the battery production line, the user can hold the unlocking rod 334 to pull the locking rod 32 away from the ratchet 31, so that the driven screw 211 can rotate in the direction of driving the clamping seat 212 close to the center of the tray 1, and then control a pair of drive motors to drive the driven screw 211 to rotate to make the two clamping seats 212 away from the power battery.
