An automatic feeding device of the assembling mechanism conveys parts, and an assembling mechanical arm is matched with a positioning clamp to accurately complete assembling of all parts of the bearing. All the mechanisms of the equipment work cooperatively, and the production and machining efficiency, quality and assembly stability of the deep groove ball bearing are improved.

This utility model discloses an electrolyzer for a water electrolysis hydrogen production device, comprising a tank body and a sealing cover. A front-end plate is located on the left side of the tank body, and a rear-end plate is located on the right side. Multiple bipolar plates are fixedly arranged at intervals inside the tank body. Between adjacent components—between the front-end plate and the first bipolar plate, between each bipolar plate, and between the last bipolar plate and the rear-end plate—a porous anode electrode, a diaphragm, and a porous cathode electrode are sequentially sandwiched, forming multiple electrolysis chambers. Each electrolysis chamber has an electrolyte inlet at its rear and an anolyte outlet and a catholyte outlet at its front, corresponding to the anode and cathode flow fields, respectively. This utility model provides a short-range, directional flow channel for each reaction unit by setting independent electrolyte inlets and anolyte outlets at the front. This design ensures that the electrolyte can be rapidly and uniformly supplied to each electrode surface, improving current efficiency and saving energy.

This application relates to the field of photovoltaic device manufacturing and testing technology, specifically disclosing a rapid testing method for the contact resistance of solar cells based on TLM (Transmission Line Model). To address the problem of large fluctuations and numerous outliers in data measured by domestically produced equipment, the method includes: S1, Sample Preparation: Using a dicing machine, the main grids of the solar cell are removed, leaving the fine grids, to prepare strip-shaped test samples, which are then fixed on a testing platform; S2, Probe Matching and Testing: Based on the fine grid spacing of the strip-shaped test samples, a matching probe model is selected, and multiple fixed strip-shaped test samples are subjected to transmission line model testing to obtain contact resistance and resistivity data; S3, Outlier Data Processing: The dataset obtained in S2 undergoes two-level filtering: significantly large outlier data is deleted; the remaining data is sorted and a trend chart is plotted, deleting step-like jump points that deviate from the overall gradual upward trend. This application effectively solves the core pain point of large data fluctuations and numerous outliers in domestically produced equipment.
