Abstract: Provided are an electrode plate wrinkling detection apparatus and cell production equipment, pertaining to the field of battery technologies. The electrode plate wrinkling detection apparatus includes an image detection mechanism and a moving mechanism. The moving mechanism is configured to drive the image detection mechanism to move on a winding machine within a region directly facing a cell and adjust a shooting angle of the image detection mechanism. The image detection mechanism includes an image capture device and a detection module that are interconnected. The image capture device is configured to photograph a cell to obtain a picture of the cell and transmit the picture of the cell to the detection module. The detection module is configured to examine the picture of the cell to detect presence of electrode plate wrinkling using a grayscale algorithm and output a detection result.

Abstract: An air guide ring for an air conditioner outdoor unit is provided. The air guide ring includes an air guide ring body. An air guide channel is defined in the air guide ring body. The air guide ring body includes a first limiting portion and a second limiting portion. The first limiting portion and the second limiting portion are configured to fit with a fixing member of the air conditioner outdoor unit and to implement bi-directional limiting, so as to prevent inward contraction deformation and outward expansion deformation of the air guide ring body from occurring.

Abstract: Disclosed is a method for reducing pressure and increasing injection by continuous operation system of biological acid acidification and nano coating, specifically including composition and preparation method of biological acidizing agent and nano coating agent. The method for reducing pressure and increasing injection by continuous operation system of biological acid acidification and nano coating of the present disclosure is able to effectively dredge the stratum water flow channel, reduce the water flow resistance, and achieve the effect of high-efficiency pressure reduction and injection increase of the water injection well.

Abstract: Provided are a method, a device, a storage medium, and a terminal for modifying account name, comprising: generating an account name modification request and calling a first modification interface to send the modification request to a server upon the condition that the case status information is that the self-service claim settlement is under review; receiving the modification request through the first modification interface and modifying the account name of the self-service claim settlement according to the request; calling a second modification interface to send the modification request to the server upon the condition that the case status information is that the self-service claim settlement is in a settled state and the transfer for the self-service claim settlement fails due to incorrect account information; receiving the modification request through the second modification interface and modifying the account name of the self-service claim settlement, re-initiating the transfer for the self-service claim
