Station count is not the whole design question
In this official factory walkthrough, Huiyao Laser’s presenter explains a revised prismatic module and PACK-line arrangement. The useful theme is how combined stations, product identity and later inspection points fit together. The visible English transcript describes one configuration; it does not establish that the same arrangement is suitable for every cell or PACK design.
1:28–2:08: Combine functions, but retain separate decisions
The presenter describes bringing OCV checking, polarity detection and nonconforming-cell handling into one station arrangement. The explanation includes voltage and resistance measurements, transfer for polarity checking and an NG buffer for cells that do not meet requirements. For a project review, list the decision made at each step even when equipment shares a footprint. Define which result blocks a transfer, how an unreadable or failed cell is identified, and how a reworked cell is reintroduced.
4:21: Preserve the cell-to-module relationship
Later in the walkthrough, an operator scans individual cell codes and binds them to a module code. The presenter describes printing a module label and applying it according to the working process. The procurement question is how this relationship is protected during rework or component replacement. Ask for a demonstration of a complete record, including the member-cell identities and subsequent processing results, rather than accepting a printed label alone as proof of traceability.
5:18–6:45: Place checks around the actual assembly risks
The narration identifies an insulation-testing step after pressing, then terminal cleaning and manual CCS installation. The presenter explains that CCS and busbar designs differ between projects. These details are a reminder to review product-specific handling and manual work instead of assuming identical automation across every proposal. Agree the insulation test method and limits, the cleaning acceptance basis and the verification of the fitted interconnection assembly. The video does not provide a universally applicable test threshold.
7:23: Use trial fixtures with a defined validation purpose
The presenter describes a fixture intended for trial welding using a cell-cap component rather than consuming a complete cell for every trial. This can be a useful topic for commissioning discussions, but a representative coupon or cap trial is not automatically equivalent to qualification on the final assembly. Ask which material, joint geometry, clamping and thermal conditions the fixture reproduces, what it does not reproduce, and which later checks use the actual product.
8:18–10:55: Distinguish module and PACK acceptance
The walkthrough moves through module end-of-line checks and transfer to a liquid-cooled PACK route. From about 9:37, the presenter divides the described PACK work into lower-case preparation and checks, component assembly, and final testing. Keep the module and PACK acceptance records distinct while preserving their relationship. The automatic transcript contains an ambiguous test acronym near the final PACK section; it is not used here to claim UL certification or any other approval.
What to request in the proposal
Ask for a process map showing the combined functions, barcode relationships, manual operations, inspection points and reject routes. Define the actual test scope, reference samples and recovery cases to demonstrate. Station consolidation may change layout and handling, but its value must be assessed against the agreed product and production basis. No source-video power setting, thickness or PPM figure is treated here as a general equipment guarantee.
