Build a More Predictable Battery Pack Line
Cheebo’s single-sided automatic spot-welding system brings feeding, sorting, labeling, welding, and front-end pack assembly into one coordinated workflow. Use the battery pack production line and battery pack assembly line as a starting point for reviewing cell formats, station scope, and production targets.
From incoming cells to welded packs
One connected front-end workflow
The line is organized around the material decisions that affect downstream welding: how cells enter, how they are grouped, how insulation is handled, and how the finished assembly is checked.
01 / FEED
Gentle loading
Whole-box loading and forward feeding move cylindrical cells into the line while reducing unnecessary handling.
02 / SORT
Cell grouping
Multi-gear sorting helps group cells by the specifications selected for the pack design.
03 / LABEL
Insulation prep
Labeling and insulation operations prepare the cell shoulder and terminal area before welding.
04 / WELD
Single-sided welding
Automatic single-sided spot welding and a fixture-flipping mechanism support repeatable access to the pack.
05 / CHECK
CCD inspection
CCD sensing provides an in-line inspection point for the configured welding and assembly process.
Product fit
Designed around cylindrical cell formats
The equipment is suited to cylindrical steel-shell cells used in pack assembly. The current product description lists 18650, 18700, 21650, 21700, 26650, 32650, and 32700 formats, with certain modules selected separately.
- Single-phase 220V, 50/60Hz power specification
- Up to 3000 PCS/hour whole-line production efficiency
- Front-end assembly typically planned around 3–4 operators
- Optional barcode scanning and internal-resistance testing can be reviewed with the equipment scope
Stability starts before the weld head
Cell presentation, sorting, and insulation are not separate from welding quality. They determine how consistently the fixture receives material and how clearly the inspection station can read the configured process.
Technical planning
Use the published figures to frame your review
Treat these values as a starting point for confirming cell dimensions, pack architecture, optional modules, and the final workstation layout.
| Planning item | Published specification | What to confirm for your line |
|---|---|---|
| Supported cylindrical cells | 18650 / 18700 / 21650 / 21700 / 26650 / 32650 / 32700 | Cell shell, terminal arrangement, pack recipe, and module selection |
| Whole-line efficiency | 3000 PCS/hour | Whether the target refers to the full configured line or a specific station |
| Operators | 3–4 for front-end assembly | Manual workstation duties and staffing at the required production rate |
| Welding motion | 350 × 600 mm XY stroke; 0.1 mm XY accuracy | Pack dimensions, fixture envelope, and weld pattern |
| Inspection | 1000W CCD pixel specification; 500 × 600 mm CCD testing scope | Inspection points, lighting, and the acceptance criteria for your product |
| Power | Single-phase 220V, 50/60Hz | Plant power, safety provisions, and final electrical configuration |
Where the line fits
Applications that depend on repeatable cell handling
The same front-end logic can be reviewed against different pack programs, provided the cell format, recipe, and station requirements are confirmed before ordering.
Power-tool battery packs
Single-sided welding and cell-format flexibility support front-end planning for cylindrical packs used in electric tools.
Portable power products
Feeding, sorting, labeling, and inspection can be considered together when a compact pack program needs a controlled input flow.
Industrial storage modules
Larger cylindrical-cell programs can be assessed against the published stroke, sorting, inspection, and staffing parameters.

Battery pack line FAQ
Start with the published configuration, then confirm the exact cell and pack requirements with Cheebo.
Which cylindrical cell sizes can the line handle?
The product description lists 18650, 18700, 21650, 21700, 26650, 32650, and 32700 cylindrical steel-shell cells. Confirm the final cell and module combination before ordering.
What operations are included in the front-end line?
The described workflow combines feeding, labeling, sorting, single-sided spot welding, and front-end pack assembly, with CCD inspection included in the technical configuration.
What production efficiency is published for the whole line?
The published technical parameters list whole-line production efficiency at 3000 PCS/hour. The applicable rate should be confirmed against the selected cell format, recipe, and configured stations.
How many operators are typically needed?
The product information states that 3–4 people can complete the front-end battery-pack assembly workflow. Staffing should be reviewed together with the manual workstation and target output.
What welding travel and inspection figures are listed?
The listed figures include a 350 × 600 mm XY welding stroke, 0.1 mm XY-axis accuracy, a 1000W CCD pixel specification, and a 500 × 600 mm CCD testing scope.
Can the equipment be customized or upgraded?
Cheebo presents equipment customization and upgrade consultation as part of the product offer. Discuss pack dimensions, optional scanning or resistance-testing modules, and the required line layout before finalizing scope.
Review the line against your pack recipe
Share the cell format, pack arrangement, expected output, and inspection requirements so the proposed configuration can be matched to the workstations you actually need.
