X Link:瞬間交聯控制

在太陽能模組中,乙烯/醋酸乙烯酯共聚物(EVA)或聚烯烴封裝保護敏感的太陽能電池免於環境傷害。EVA分子間交聯和聚烯烴的程度是決定一個模組的長期穩定性和校能的因素。交連是透過在層壓製程中熱固化聚合物達成。
X Link 系統實現快速、自動化、非破壞性且準確地在層壓後立即評估 EVA 或聚烯烴的交連程度。X Link 可整合進任何太陽能模組生產線,對流程和品質管控提供100%的覆蓋率。

線上版本

用於在線應用中,測量頭可被整合到層壓機的冷壓器中,或生產線的其他部分。運用多量測頭可以判斷中心到邊緣的均勻性。如此一來,X  Link 有助封閉迴路回授製程控制和品質保證。

離線版本

離線版本是專為實驗室應用、人工處理生產線、研發實驗室和試產線所設計,不論有無框架,皆可測試完整大小的量產模組。研發實驗室甚至可以測試 EVA 或聚烯烴膜,無需玻璃或背板。可進行高解析比對交聯程度和統計評估。
此外,手動離線版本允許可多點測量層壓、停產模組和來自現場的模組。對於模組製造商、投資人、認證單位和顧問來說,這是非常實用的品質控制工具。
使用 X Link 離線版本對於工程師和作業員來說都很簡單。有雷射束的指引,使用者可輕鬆定位模組於量測頭下。此裝置配備觸控面板,以容易使用的軟體控制測量過程。

X Link® SAM: semi automated mapping system

PV module lamination control: Mapping of curing state of encapsulant across the whole moduleX Link® SAM is a semi-automated X Link mapping system which  creates maps of the curing state of full-size modules. After loading a module into the device, the tool measures the degree of cross-linking at predefined positions on the module with a typical measurement time of less than one minute per point. The whole measurement procedure is non-destructive and does not affect the functionality of the tested modules. Presentation of the measured data as color maps give immediate information on the uniformity of the curing state of the encapsulant across the whole module.

The X Link® SAM has been developed with focus on regular spot tests in production lines and delivery control. Used in a production line, it gives fast feed-back on homogeneity in the lamination process, allowing quick reaction on production issues. In delivery control it allows to check the quality of the encapsulation, spotting quality issues at a glance.

優勢

隨著X Link 的直接回授快速最佳化層壓過程,透過調整加熱區和層壓時間,達到優化的交聯品質。如此實現完美的層壓製程,掌握高品質模組生產的關鍵。

X Link® in mass production

X Link® offers a lot of benefits for mass production of PV modules. Hanwha Q CELLS GmbH (Germany) published recently the results of their X Link® evaluation. Their tests have shown that the tool provides extremely accurate measurements, faster and more exact process control, quality control, recipe evaluation as well as laminator characterization. All this enables an early failure detection and saves costs! Find more in our summary of Hanwha’s technical paper  …more>

Calibration

High accuracy of X Link® systems is indispensable for process control and quality management in solar module production. It is recommended to calibrate X Link® after its delivery or moving as well as once a year to fulfill the requirements of quality auditors. To guarantee X Link's high precision, LayTec offers X Cal - a set of high precision equipment for on-site calibration of X Link® systems.
