[0127] Please refer to Figures 1 - 11 , one embodiment of the present invention provides a processing component 100, including:

[0128] A large-packaging feeding section 110, which is used for feeding the battery cells and performing pre-processing; and

[0129] A battery cell processing section 120, which is used for performing pitch stacking on the qualified battery cells processed by the large-packaging feeding section 110 to facilitate the processing of subsequent processes;

[0130] Among them, large-packaging feeding means that the incoming battery cells are not bare battery cells, but are arranged in boxes after being packaged with packaging materials and bottom pallets to meet the safety requirements during the installation process of the battery cells. In the industry, it is generally called "large-packaging". The packaging materials therein include elastic materials such as foam and rubber, and the bottom pallets include pallets, trays, card slots boxes, etc. Large-packaging: The incoming battery cells not only include the battery cells themselves, but also the battery cell packaging materials and bottom pallets. This whole is called large-packaging, so it is commonly called "large-packaging feeding".

[0131] As needed, a first conveying unit 130 is disposed through the working area of the large-packaging feeding section 110 for conveying the battery cells and sequentially passing through the working area of the large-packaging feeding section 110 along the processing procedure direction, so that the large-packaging feeding section 110 performs pre-processing on the battery cells in sequence; the battery cell processing section 120 is disposed behind the first conveying unit 130 along the processing procedure direction, so that the battery cell processing section 120 places the battery cells conveyed in place by the first conveying unit 130.

[0132] A first conveying unit 130 is disposed between the large-packaging section and the battery cell processing section 120, and the first conveying unit 130 is used for conveying the qualified workpieces processed by the large-packaging feeding section 110 to the battery cell processing section 120.

[0133] In this embodiment, the first transfer unit 130 includes a first tray and a first transmission mechanism. The first tray is matched with the battery cell for limiting and fixing the battery cell, and a plurality of battery cells can be placed on the first tray. The first tray is used in cooperation with the first transfer mechanism. The first tray is arranged on the first transmission mechanism and moves through the first transmission mechanism. During operation, the battery cells are placed on the first tray for positioning, and the first tray slides on the first transmission mechanism, thereby realizing the transfer of the battery cells to each process for processing.

[0134] Specifically, the battery cells are pre-processed (pre-processing) through the large-packaging feeding section 110, and the pre-processing includes bottom cleaning, surface cleaning, and code scanning detection of the battery cells, etc., to ensure the qualified transportation of the battery cells. The battery cell processing section 120 stacks the battery cells with variable pitch, and the battery cell processing section 120 plays a role of connecting the front and the back, meeting the modular and automated settings of the production line, and greatly ensuring the production stability and efficiency.

[0135] In one of the embodiments, the large-packaging feeding section 110 includes:

[0136] A large-packaging feeding unit 211111, which includes a large-packaging incoming material placement position 111-1 and a large-packaging feeding robot 111-2. The large-packaging incoming material placement position is used for feeding, removing foam, and / or pallets, and the large-packaging feeding robot 111-2 is used for grasping and moving the workpiece on the large-packaging incoming material placement position 111-1;

[0137] A battery cell bottom cleaning unit 112, which is used for cleaning the bottom of the battery cell; and

[0138] A code scanning and detection unit 113, which is used for code scanning and detecting the battery cell;

[0139] Wherein the large-packaging incoming material placement position, the large-packaging feeding robot 111-2, the battery cell bottom cleaning unit 112, and the code scanning and detection unit 113 are arranged in sequence from front to back in the process processing direction; the large-packaging incoming material placement position and the battery cell bottom cleaning unit 112 are arranged within the working range of the large-packaging feeding robot 111-2. The first transfer unit 130 is arranged behind the battery cell bottom cleaning unit 112 along the processing procedure direction, so that the first transfer unit 130 transports the battery cells processed by the battery cell bottom cleaning unit 112.

[0140] In this embodiment, there are three large-packaging incoming material placement positions 111-1. The three feeding stations have no sequence priority and simultaneously serve the functions of feeding, placing lower foams and / or pallets. The three large-packaging incoming material placement positions 111-1 are arranged side by side. The large-packaging feeding robot 111-2 is arranged behind the three large-packaging incoming material placement positions 111-1 along the processing procedure direction. The bottom cleaning unit 112 of the battery cell is arranged behind the three large-packaging incoming material placement positions 111-1 along the processing procedure direction. The large-packaging feeding robot 111-2 and the bottom cleaning unit 115 of the battery cell can be arranged side by side or successively along the processing procedure direction behind the three large-packaging incoming material placement positions 111-1. The large-packaging incoming material placement position and the bottom cleaning unit 112 of the battery cell are set within the working range of the large-packaging feeding robot 111-2. The packaging materials include foams, pallets and other materials for outer packaging of the battery cells.

[0141] Among them, the large-packaging feeding robot 111-2 is a multi-directional movement robot. The multi-directional movement robot has multiple movement joints. The multiple movement joints can respectively rotate 360 degrees on the X, Y and / or Z-axis planes. A gripper is installed at the end of the large-packaging feeding robot. The gripper is used to pick up the battery cell. By combining the use of the large-packaging feeding robot and the gripper, the battery cell on the large-packaging incoming material placement position 111-1 can be picked up efficiently and accurately, moved to the bottom cleaning unit 112 of the battery cell, and after the cleaning is completed, the battery cell is placed on the first tray on the first conveyor mechanism.

[0142] Steps of large-packaging feeding: The foam battery cell is in place and reaches the large-packaging incoming material placement position 111-1. The large-packaging feeding robot 111-2 is at the origin. The large-packaging feeding robot 111-2 works, moves to above the battery cell for distance measurement and takes a photo. The position of the battery cell is identified through distance measurement and photo taking. The gripper of the large-packaging feeding robot 111-2 descends to pick up the battery cell. After the large-packaging feeding robot 111-2 picks up the battery cell, it moves to the bottom cleaning position.
