Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a correction mechanism for cylindrical batteries. Background Technology

[0002] Battery electrolyte filling is a crucial step in battery production. After the battery is clamped and secured by a clamping mechanism, the electrolyte inlet is aligned with the filling equipment.

[0003] Existing battery filling and clamping equipment typically uses a gravity-fed clamping mechanism. When a battery is placed into this mechanism, the bottom tray of the clamping device moves downwards under gravity; the bottom tray then drives multiple clamping jaws to rotate synchronously, thus securing the battery. While this gravity-fed clamping mechanism is simple in structure and requires no active power source, its design relies on the battery's weight. When the battery type changes, the weight alters, resulting in varying clamping forces. For lighter batteries, insufficient clamping force during rotational correction can easily lead to displacement, affecting the quality of subsequent battery processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a correction mechanism for cylindrical batteries.

[0007] The clamping assembly is a gripper cylinder; each gripper toe of the gripper cylinder is fixed with a clamping block; the clamping blocks are distributed circumferentially outside the battery cell support plate.

[0008] In a preferred embodiment of this utility model, a fixed base is fixed on the base plate; a rotating shaft is rotatably connected to the fixed base; the cylinder fixing plate is fixed on one end of the rotating shaft; and the other end of the rotating shaft is fixed on the rotating assembly.

[0009] In a preferred embodiment of the present invention, the rotating assembly includes a rotating module with one end fixed to a base plate, an active synchronous pulley fixed to the other end of the rotating module, and a driven synchronous pulley fixed to a rotating shaft; a synchronous belt is tensioned between the driven synchronous pulley and the active synchronous pulley.

[0010] In a preferred embodiment of this utility model, a sensing plate is fixed on the cylinder fixing plate; a photoelectric sensor is fixed on the fixing base; and the photoelectric sensor is arranged on the movement path of the sensing plate.

[0011] In a preferred embodiment of this utility model, the gripper cylinder is a three-jaw cylinder.

[0012] In a preferred embodiment of this utility model, the battery cell support plate has a slot in the middle.

[0015] In a preferred embodiment of this invention, the rotating module is a servo motor.

[0017] With the above structure, the beneficial effects of this utility model are as follows: After the battery is placed into the cell tray by the robotic arm, the gripper cylinder drives the clamping block to move and clamp the battery in place. Then, the required rotation angle of the battery is calculated by taking an image of the cell surface using an external CCD camera. The rotating component drives the gripper cylinder and the cell tray on the cylinder fixing plate to rotate, thereby realizing the rotation of the battery. In this structure, the battery is clamped and fixed by the gripper cylinder, which makes the clamping more stable. The servo motor has high rotational accuracy, and the battery rotation angle is more precise, thus ensuring the quality of subsequent battery processing. Attached Figure Description
