Description

Technical Field

[0001] The utility model relates to the technical field of battery cell jigs, in particular to a battery cell gripper jaw. Background Art

[0002] A battery cell is a single battery in a lithium battery pack, which provides power but is not directly used externally. In the new energy era, as the core component of various portable electronic devices and electric vehicles, the importance of battery cells is self-evident. A battery cell is the basic unit of a lithium battery, usually including a positive electrode, a negative electrode, a separator, and an electrolyte, etc. These components work together to store and release electrical energy through the migration of lithium ions between the positive and negative electrodes. Battery cells can be divided into three types according to their packaging forms: cylindrical battery cells, soft-pack battery cells, and square battery cells. Different types of battery cells are suitable for different application scenarios due to their different structures and characteristics.

[0003] During the production process of battery cells, the completed single battery cells need to be placed in a foam material box, neatly stacked, and then transported to the production line. The battery cells are taken out by a robotic arm and then assembled into a complete battery.

[0004] However, after the battery cells placed in the foam material box are taken out, the foam material box still remains stacked in place. It is necessary for the staff to remove the foam material box and then place a new foam material box with battery cells before the next round of battery cell picking can be carried out. In view of this, this application proposes a battery cell gripper jaw. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a battery cell gripper jaw, which has the advantages of setting a foam clamping component for clamping the foam material box on the robotic arm, etc., and solves the problem that after the battery cells placed in the foam material box are taken out, the foam material box still remains stacked in place, and it is necessary for the staff to remove the foam material box and then place a new foam material box with battery cells before the next round of battery cell picking can be carried out.

[0006] To achieve the above object, the utility model provides the following technical solution: A battery cell gripper jaw, including a mounting base, a robotic arm is rotatably mounted on the top of the mounting base, a connecting flange plate is fixedly mounted at one end of the robotic arm, a grasping bottom plate is fixedly mounted at the bottom of the connecting flange plate through an anti-collision component, a battery cell gripper jaw is arranged at the bottom of the grasping bottom plate, and two foam clamping components are arranged at the bottom of the grasping bottom plate;

[0007] The foam clamping component includes two clamping guide rods that slide through the bottom of the grasping base plate. The bottom ends of the two clamping guide rods are fixedly installed with a clamping base plate. The bottom of the clamping base plate is fixedly installed with a clamping cylinder. The movable end of the clamping cylinder is fixedly installed with a clamping L-shaped plate. The top of the grasping base plate is fixedly installed with a downward moving cylinder, and the movable end of the downward moving cylinder is fixedly connected to the top of the clamping base plate.

[0008] Furthermore, a camera mounting plate is fixedly installed on the top of the grasping base plate. A positioning camera is fixedly installed on the bottom of the camera mounting plate, and the lens of the positioning camera extends below the grasping base plate.

[0009] Furthermore, a light source bracket is fixedly installed on the bottom of the grasping base plate. A supplementary light board is fixedly installed on the bottom of the light source bracket, and a through hole aligned with the lens of the positioning camera is opened at the center of the supplementary light board.

[0010] Furthermore, a pressing guide rod passes through the top of the grasping base plate, and a pressing plate is fixedly installed at the bottom end of the pressing guide rod.

[0011] Furthermore, a pressing cylinder is fixedly installed on the top of the grasping base plate, and the movable end of the pressing cylinder is fixedly installed on the top of the pressing plate.

[0012] Furthermore, the anti-collision component includes four sliding bearings fixedly installed at the bottom of the connecting flange plate. The four sliding bearings are distributed at the four corners of the connecting flange plate. An installation guide rod is slidably installed inside the sliding bearing. The grasping base plate is fixedly installed at the bottom of the installation guide rod. A locking sleeve is fixedly installed at the top end of the installation guide rod, and a sensor aligned with the locking sleeve is fixedly installed on the top of the connecting flange plate.

[0013] Furthermore, the number of the battery cell grippers is ten, and a spacing adjustment component for adjusting the spacing between the battery cell grippers is arranged on the top of the grasping base plate.

[0014] Compared with the prior art, the present utility model provides a battery cell gripper, which has the following beneficial effects:

[0015] 1. For this battery cell gripper, by arranging a foam clamping component on the top of the grasping base plate, after taking out the battery cells from the foam material box, the downward moving cylinder drives the clamping base plate to move downward, so that the clamping L-shaped plate is located on both sides of the foam material box. Then, the clamping cylinder drives the clamping L-shaped plate to clamp the foam material box, and the mechanical arm is used for blanking. This solves the problem that after taking out the battery cells placed in the foam material box, the foam material box still piles up in place. It is necessary for the staff to take away the foam material box and then place a new foam material box with battery cells before the next round of battery cell picking can be carried out.

[0016] 2. The battery cell gripper is provided with an anti-collision component on the connecting flange plate. The anti-collision component is connected to the grasping bottom plate. When the grasping bottom plate descends and the cell gripper contacts the battery cell, if the grasping bottom plate continues to descend, the battery cell will push up the grasping bottom plate, causing the installation guide rod to move upward, causing the locking sleeve to move upward, and the sensor to be misaligned with the locking sleeve, detecting that the grasping bottom plate has reached the designated position, thus preventing the grasping bottom plate from continuously descending and crushing the battery cell.
