The method includes the following steps that S1, the front surface of foil with a coating is coated with slurry, and then is conveyed to a first drying oven to be dried; the first drying oven is divided into a first section, a second section, a third section, a fourth section and a fifth section which are sequentially arrayed in the conveying direction of a coating machine; S2, the back surface of the single-surface coated pole piece obtained in the first step is coated with slurry and then is conveyed to the first drying oven to be dried; S3, the double-surface coated pole piece obtained in the second step is placed in a second drying oven to be dried. By means of the method for coating the lithium ion battery pole piece, solvent in the battery pole piece can be evenly volatilized, the abnormal appearance problem of the pole piece is solved obviously, the homogeneity and cohesiveness of the pole piece are guaranteed, the quality of the pole piece is improved and the yield of the pole piece is increased.

Provided is a skin masking material that is attached to the skin in order to hide a site that is considered to be abnormal in appearance when the skin has an abnormal appearance, and when cosmetics are applied to the surface of the attached skin masking material, makeup sex is good. A skin masking material in which an adhesive layer is laminated on one side of a stretchable film layer, the average particle diameter of a powder contained in cosmetics coated on the other side of the film layer is denoted as d, and the thickness of the film layer is When written as w, Rz on the other side satisfies d≤Rz≤60d and Rz≤w. Since Rz on the other surface is as large as the average particle diameter d or more, powders of cosmetics often enter the unevenness formed on the other surface and are held in the unevenness.

The invention relates to a tool for assembling a yaw damper of a bogie. The tool comprises a base plate seat, wherein the base plate seat is provided with a locating block and a locating support, the locating block corresponds to a base plate groove of the yaw damper, the outer side surface of the locating support is provided with a fixing nut, a lead screw is arranged in the fixing nut, a locating pin is arranged at the front end of the lead screw and is matched with a locating hole of a yaw damper torsion rod, the back end of the lead screw is connected with a handle, the top of the locating support is provided with a limiting groove for limiting the end of the yaw damper torsion rod, and the inner side of the locating support is provided with magnetic sheets for respectively adsorbing the yaw damper torsion rod, a vertical plate and left and right side plates. According to the tool for assembling the yaw damper of the bogie, disclosed by the invention, the magnetic sheets replace the traditional lead screw to clamp the tool, and a jack-out demoulding method of a central locating pin is additionally provided so that a problem that a tool with the abnormal appearance is unlikely to be clamped is smartly solved, the self size and the clamping complexity of the tool are largely reduced, and the manufacturing cost of the tool is saved; and meanwhile, the clamping time of tool assembly by labors is largely shortened and the production efficiency is improved.

The invention discloses a signal-abnormal-assistant positioning circuit and method. The signal-abnormal-assistant positioning circuit is mainly composed of a counting module, an edge detecting module and an abnormal-position output module; the counting module carries out clock period counting on a to-be-detected signal, an effective signal overflowed through counting of the counting module is fed into the abnormal-position output module, and the abnormal-position output module is used for judging an output signal of an abnormal position is effective or not; the edge detecting module is used for detecting changes of a rising edge of the to-be-detected signal or changes of a falling edge of the to-be-detected signal, and effective output of edge detection is fed into the counting module for zero clearing; the abnormal-position output module is used for marking the abnormal position of the to-be-detected signal. According to the technology of the signal-abnormal-assistant positioning circuit and method, a marking signal is grabbed through logical analysis software, the circuit state when the to-be-detected signal is abnormal can be rapidly and accurately positioned, abnormal appearance reasons are convenient to analyze and find, the debugging verification efficiency is improved accordingly, and the development cost is reduced.

The present invention provides a polarizing film with an adhesive layer that prevents appearance abnormality at the edge of the polarizing film, which is a unique problem when reducing the thickness of the polarizing film. A polarizing film with an adhesive layer comprising: a polarizing film having a transparent protective film on at least one side of a polarizer and having a total thickness of 100 μm or less; and an adhesive layer containing a (meth)acrylic polymer , wherein the adhesive layer contains an antioxidant. The adhesive layer of the polarizing film with an adhesive layer preferably contains a crosslinking agent, and the crosslinking agent is preferably at least one of a peroxide and an isocyanate-based crosslinking agent.

The invention provides a product inspection system and method, which relate to the technical field of appearance quality inspection, including a dark box, an image collector, lighting equipment, a positioning limiter, a controller, and a conveying mechanism; wherein, the lighting equipment provides lighting for the dark box; the conveying mechanism The installed sensor sends the identification code of the target product to the controller; the positioning limiter limits the target product on the conveyor belt to the dark box, and sends a positioning signal to the controller; the controller triggers after receiving the positioning signal The image collector collects the image data of the target product, recognizes and judges the image data bound with the identification code, and issues an abnormal alarm for the abnormal appearance of the target product. This system can realize the automatic control process of inputting the identification code of the target product, judging the appearance of the target product, and alarming the abnormal shape, avoiding the process of judging the quality of the target product with the naked eye and registering the abnormal appearance of the product, and improving the quality inspection efficiency of the target product .
