Detailed equipment flow description

Layout introduction

Parameter introduction:

1. Layout plant size (L*W*H): 35m*9m*3m (may change with the refinement of the plan, the picture is for reference only) 2. Main functions: The design of the production line is divided into cell section and module section; the function of cell section is to process the sorting of cells after going online, cell surface cleaning, cell gluing, cell stacking; module section The functions include scanning code binding, pole cleaning, module welding, and post-welding EOL detection after the module is online.

Cell section introduction

Parameter introduction:

1. The total size of the cell section (L*W*H) is: 15m*4.6m*2.5m high; 2. The main functions of the battery cell section equipment: after the battery cell is online, the battery cell is sorted, the outer surface of the battery cell is cleaned by plasma, the battery cell is glued, the battery cell is stacked, and the module is offline and stand still.

Functional module design description-sorting/cleaning station

Function Description:

1. The equipment mainly realizes the functions of cell sorting and cell cleaning; 2. Work flow: After the cells are online, the cells are sorted, and the qualified cells are flowed into the next station. The unqualified cells are automatically picked out by the NG material mechanism to the unqualified assembly line; the qualified cells enter the cleaning station and automatically conduct electricity. Plasma cleaning of the core surface automatically flows into the next station after cleaning; automatic operation from loading to unloading, and the operation of the equipment and status feedback are controlled by the console.

Functional module design description-glue application station

Function Description:

1. This equipment mainly realizes the function of cell gluing; 2. Work flow: The operator puts the battery into the gluing position of the dispenser after taking the battery at the battery take-out position. The three-axis gluing mechanism drives the gluing head to apply the glue according to the set gluing track. After the gluing is completed, the glue is applied Manually take it out and put it on the buffer line; the glue applicator is divided into left and right double stations to run. 3. The station is a dual-line parallel station, composed of two dispensers, which can operate on a single line alone or on two lines at the same time.

Functional module design description-stacking extrusion station

Function Description:

1. This equipment mainly realizes battery cell stacking, extrusion, bundling and packaging; 2. Work flow: After the glue-coated batteries are placed in the upper material position in turn, manually push into the extrusion position, start the extrusion mechanism button to make the batteries squeeze to the set pressure, put them into the strapping steel band, and then squeeze The pressing mechanism is retracted, and the squeezed module is manually retracted to the loading position. The cantilever crane and the stationary bottom plate are hoisted into the stationary trolley and pushed to the stationary area to stand still. 3. The station is divided into left and right stations, which can realize interchangeable double station operation such as station 1 extrusion and station 2 loading.

Functional module design description-module scan code/cleaning station

Function Description:

1. This equipment mainly realizes the module scan code binding and pole photo cleaning after the module goes online; 2. Work flow: The finished module is hoisted from the gantry crane to the loading position of the module. The module flows into the scan code binding position with the pallet. After lifting and positioning, manually hold the scan gun to the cell QR code and end plate The QR code is scanned sequentially. After the entry is completed, it flows into the pole cleaning position. After the position is visually photographed and checked, the pole cleaning is performed. After the cleaning is completed, it flows into the next station.

Functional module design description—module welding station

Function Description:

1. This equipment mainly realizes module pole welding; 2. Work flow: After the module has placed the adapter sheet, it flows into the station. After the jacking and positioning, the visual photograph is taken and the distance measurement record data is sent to the control system for welding position compensation. After the data is completed, the welding is automatically started, and the welding is completed. The positioning is opened, and the module flows into the next station with the tray.

Functional module design description—EOL inspection station

Function Description:

1. This equipment mainly realizes module performance testing after module welding, and is a manual auxiliary station; 2. Work flow: After the module is welded, it flows into the station. After the jacking mechanism is positioned, the operator connects the test plug with the module interface, and then activates the detection button. After the test is completed, the operator removes the connector and flows into the next job. Bit

Functional module design description-tray introduction

Function Description:

1. This component is located on the circulating tray on the welding assembly line, and the battery cell module is loaded for circulation on the double-speed chain; 2. Work flow: After putting the battery core into the tray, the locking mechanism locks the battery core.

Functional module design description-introduction to the trolley

Function Description:

This part is the operating tooling, which mainly transfers the extrusion module to stand still, and the module is welded on-line and off-line for transfer.
