Battery Manufacturing EquipmentCylindrical laser cutting and winding integrated machine
QINTIAN's integrated machine unwinds both electrodes, laser-cuts the tabs, inspects for defects, corrects web position, cuts the electrode and winds it with separator into a cylindrical cell. The catalogue lists cells from 30–70 mm in diameter and 70–320 mm in height, with a tab-bending function.

Process steps and the 30–70 mm cell range
QINTIAN's catalogue lists positive and negative electrode unwinding and alignment, laser tab cutting, defect inspection, moving-web correction, electrode cutting and winding with separator into a cylindrical cell. This integrated machine covers cells of 30–70 mm diameter and 70–320 mm height.
QINTIAN's standalone large-cylindrical winder covers a different height range, 80–350 mm, and other winding models list 3 m/s speeds. Those figures belong to those machines. The catalogue entry for this integrated machine gives no finished-cell rate, so ask for one in the quote.
The page mentions a tab-bending function. Ask which tab shapes and materials it handles and whether folding is part of the quoted configuration.
| Parameter | Published value | Record status |

| Process sequence | Laser tab cutting, defect inspection and separator-assisted winding | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Run your cut electrode all the way into a wound cell
Send the foil and coating details, electrode width and length, tab layout, separator and cell size. Agree how cut edges are inspected, how particles are handled and which positions are measured in the wound cell. Fitting the outer diameter is only the first check; the internal electrode design has to work too.
Ask for the reject path, the identity records and how the machine recovers from a broken web or a failed inspection. Agree the roll-change and product-change procedures, and judge the first accepted cell after each one. Accept the machine on the full cut-and-wind process, with a cutting demonstration as one part of it.

Test the integrated jelly-roll route at your format
Ask for a current drawing of this integrated model showing the cutting and winding layout and its cell range. Keep the standalone winder's dimensions in a separate comparison table. Supply real web materials, electrode sizes and the intended roll geometry so the supplier can explain the tooling and material path it proposes.
In the trial run, link each laser-edge observation to the jelly rolls made from that material. Set definitions for edge damage, debris, alignment and handling faults with your quality team, then count good rolls and rejects across an agreed full cycle. Include stops, restarts and material changes, because recovery matters as much as steady speed. Collect the approved process and maintenance documents at the end. Judge the integrated machine on its own trial results at your format.

Track flagged material through cutting, winding and rejection
Before the trial, agree the defect classes and what happens to flagged electrode material. Ask the supplier to show how a flagged section is followed through cutting and winding, including when a stop or restart shifts the material position. Ask whether an automatic reject mechanism is part of the quoted scope.
Inspect the wound cells at your chosen format, with tab geometry, alignment and any folding step shown on the drawing. Count usable cells apart from web metres and machine cycles. Production rate and cut quality for this machine come from your trial records.
Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Does the cell fit the integrated model? | This machine lists 70–320 mm cell height; the standalone winder lists 80–350 mm. | Send diameter, height and electrode drawings for the quoted configuration. |
| Can the complete cycle meet the quality target? | The catalogue describes the cutting and winding steps with no accepted-roll rate. | Trial your own materials and inspect edges, alignment and rejected rolls. |
Equipment questions
Does the standalone winder's height range apply here?
No. This integrated machine is listed at 70–320 mm. Match each size range to its own machine and ask for the product drawing.
Source s2What is the finished-cell production rate?
The catalogue entry gives none. Ask QINTIAN for a rate tied to your electrode length and geometry, the auxiliary steps included and the acceptance criteria.
