This invention relates to a method for precise oil sales targeting based on user profiles, comprising: acquiring vehicle attribute data, historical refueling behavior data, geographic location trajectory data, and promotional response feedback data of target users; and constructing a multi-dimensional user profile based on the vehicle attribute data, historical refueling behavior data, geographic location trajectory data, and promotional response feedback data, including vehicle type tags, refueling frequency tags, fuel preference tags, geographically active area tags, and promotion sensitivity tags. This method for precise oil sales targeting based on user profiles constructs a multi-dimensional user profile system specifically for oil sales scenarios, deeply integrating four core dimensions: vehicle attributes, refueling behavior, geographic location, and promotional response. It overcomes the shortcomings of general advertising push models that rely on online behavioral data and are disconnected from offline refueling scenarios.

The utility model discloses a kind of pole piece single winding mechanism, battery cell winding device and battery processing equipment, pole piece single winding mechanism includes pedestal, winding needle and pressure assembly, winding needle is rotatably arranged in the pedestal, for winding pole piece;The pressure assembly includes fixing piece, swing arm and press roll, the fixing piece is installed in the pedestal, and located in one side of the winding needle, one end of the swing arm is rotatably connected with the fixing piece, and the other end is rotatably connected with the press roll, the axial direction of the press roll is same with the axial direction of the winding needle, to resist the pole piece on the winding needle;Two bearings are arranged at the rotatable connection of the two ends of the press roll and the swing arm, and at least one bearing is provided with a dustproof piece on the side facing the outside. The pole piece single winding mechanism of the utility model technical scheme can improve the opening rate, improve the processing efficiency and save the cost.

The utility model discloses a kind of shower head height direction stepless adjustment mechanism for thin film deposition equipment, it is related to the technical field for thin film deposition equipment, the utility model aims at solving how to adjust the problem of shower head in not opening cavity, the utility model includes vacuum cavity and shower head, the shower head is installed in the inside top of vacuum cavity, insulating ceramic is sleeved on the outer wall of the shower head, annular protrusion is arranged on the inner wall top of the insulating ceramic, the outer wall top of the shower head is formed into the boss that can be clamped below annular protrusion. Shower head height direction can be adjusted within a certain range, by adjusting, an optimal height can be determined, so that plasma field density increases, thin film uniformity is better, improves thin film deposition efficiency and film formation cleanliness, by directly adjusting shower head height outside cavity, reduce opening cavity process, can make maintenance time shorten, improve equipment open rate, cavity particle pollution caused by opening cavity is also reduced simultaneously.
