The invention discloses a production line for sawing, sorting, and recycling waste storage batteries. The production line comprises a bottom seat, a battery feeding roller way, a sawing device, which is arranged on the bottom seat, a hydraulic system, and an electrical system; the bottom seat is also provided with a sawing transportation track, a battery cover collecting roller way, a polar plate collecting roller way, and a battery box collecting roller way; the heights of the battery cover collecting roller way, the polar plate collecting roller way, and the battery box collecting roller way are all lower than the height of the sawing transportation track, the sawing transportation track is provided with a servo overturning trolley, the height of the servo overturning trolley matches with the height of the sawing device, the battery feeding roller way is provided with a storage battery pushing and positioning device, the height of the storage battery pushing and positioning device matches with the height of the servo overturning trolley, and the battery cover collecting roller way is arranged right under the sawing device. The production line prevents an operator from contacting the storage batteries, reduces the harms to the body of the operator; avoids the pollutions to air and water, and achieves the re-utilization of resources.

The invention belongs to the technical field of anti-counterfeiting of materials, in particular relates to anti-counterfeiting paper with intelligent micro two-dimensional codes. The anti-counterfeiting paper with the intelligent micro two-dimensional codes is formed by a lower paper layer, a base material layer, an intelligent micro two-dimensional code layer and an upper paper layer sequentially from bottom to top, wherein the two-dimensional codes are square, and the edge length of each two-dimensional code is 1mm to 6mm. The invention also relates to a preparation method of the anti-counterfeiting paper with the intelligent micro two-dimensional codes. The preparation method comprises the following steps of microprinting, die cutting and papermaking, wherein at least one die-cut micro two-dimensional code is arranged on the area of every 10 to 50 square centimeters. The prepared intelligent anti-counterfeiting paper has the characteristic that the edge length of each two-dimensional code is only 1mm to 6mm, the occupation area is small, and the storage amount of other information is not influenced. The intelligent micro two-dimensional codes cannot be read by virtue of the normal photographing of a mobile phone, the information inside the intelligent micro two-dimensional codes only can be inquired by virtue of the photographing of a more-than-50-time magnifying lens, and thus the counterfeiting difficulty is increased. When the information in the micro two-dimensional codes is inquired by a customer, the hidden two-dimensional codes need to be taken out to be read in a magnifying and scanning manner, the anti-counterfeiting paper is damaged, and thus the reutilization of the anti-counterfeiting paper is prevented.

The portable combined range of the invention belongs to the cooker field, which is a portable combined range with the pan and the oven as an organic whole, including a bracket, a firing cup, a pan body, a handle. The bracket 9 is composed of a chassis 29, a lateral wall 32, an inner cover 28. The firing cup 10 is mounted on the bracket chassis 29 and in the inner cover 28. The lining has a multilayer housing 7 of the exhaust vent 35 mounted between the bracket inner cover 28 and the lateral wall 32. The housing hoisting orientation mechanism is disposed between the housing 7 and the lateral wall 32. The pan body is arranged above the firing cup 10 supported on the housing 7 to compose the portable combined range. Compared to the existing technique, the invention has: 1. changing the fixed distance style of the traditional range through the hoisting and the congruence of the oven to make the volume smaller, compact, reasonable and convenient to carry; 2. changing the traditional air combustion-supporting way and the cyclic form to advance the thermal efficiency; 3. the hurricane lamp effect is good, whether blowing wind or raining , the invention can be used normally; 4. lifted in the hand or hung up during the usage process with simple operation and convenient usage, also disposed on the flat or the plane. The invention can expediently solve the problems when the users have dinner outdoors.

Embodiments of the present application provide an information processing method and device. The method includes: after determining that the login message from the first source address satisfies the preset credential stuffing rule, when receiving each login message from the first source address, sending a message for each login message to the first source address The authentication failure information of the document; construct the corresponding authentication message according to the login information in each login message, and send the constructed authentication message to the first server; receive the verification returned by the first server for the login information in the authentication message Result; according to the verification result, the successfully verified login information is determined as leaked login information; wherein, the login message includes the login information used to log in to the first server. Applying the solutions provided by the embodiments of the present application can improve information security.

The disposable microneedle device includes a base, a microneedle assembly, a cover body, and several connecting rods that can be dissolved in alcohol; the microneedle assembly includes a base and several microneedles arranged at intervals on the base; the top of the base The same number of conical grooves as the connecting rods are provided on the wall and the bottom wall of the base; the two ends of each connecting rod are all tapered, and one of the ends of each connecting rod is embedded in the bottom wall of the base. Corresponding to a tapered groove, the other end of each connecting rod is embedded in a corresponding tapered groove on the top wall of the base; several connecting rods are arranged at intervals to form an equilateral triangle array; the cover is detachable Fastened on the base, a closed space is formed between the cover and the base, and the microneedle assembly and the connecting rod are located in the closed space. The above invention can effectively prevent secondary use and fundamentally avoid cross-infection.
