The invention discloses a cylindrical battery and a manufacturing method thereof, which relate to the field of lithium ion battery manufacturing. The structure is simple. The height of a roll core canbe reduced to a certain extent by arranging a tab on one end surface of the roll core, and meanwhile, only one end of a shell can be opened and sealed, so that the overall weight of the cylindrical battery is reduced; according to the manufacturing method of the cylindrical battery, compared with a pole piece using full tabs in the prior art, the laser cutting of the pole piece is additionally arranged on the process, and through the cooperation of the laser cutting and the subsequent welding and kneading process of the tabs, a positive tab area, a negative tab area and a non-tab area can beformed at one end of a roll core formed by winding a positive plate and a negative plate, and a non-welding area between tabs is omitted, so that the contact compactness between the positive tab and the negative tab after winding is reduced, and the speed of infiltrating the positive plate and the negative plate by electrolyte can be increased during subsequent injection of the electrolyte; and the production efficiency of the cylindrical battery is effectively improved.

A liquid crystal display (LCD) panel is provided. A pixel structure of the LCD panel has an asymmetrical liquid crystal alignment. The LCD panel is divided into an array of display blocks. When the LCD panel is in a narrow viewing angle display mode, some of the display blocks are disabled or darkened so that a displayed image is interfered by the disabled or darkened display blocks when it is viewed from the side. Thereby, an anti-peep effect is achieved.

The invention discloses an excavator bucket tooth which comprises two parts, namely a tooth seat and a plurality of tooth tips, wherein the tooth seat and the plurality of tooth tips are cast independently; the tooth tips are fixed at the front end of the tooth seat side by side; a gap is formed between every two adjacent tooth tips; the roots of the tooth tips are circular; the heads of the tooth tips are in circular arc shapes; the thicknesses of each toot tip is slowly reduced from the root to the head; the bucket tooth is divided into the two parts, namely the tooth seat and the tooth tips which are cast independently, each tooth tip is coated in the tooth seat, the contact area between each tooth tip and the tooth seat is enlarged, the bonding strength of each tooth tip and the tooth seat is greatly improved, and the possibility of falling off of the tooth tips is reduced; due to the creative shapes, the tooth tips can keep sharp all the time; when the excavator bucket tooth is used for excavation, time and labor are saved, and the service life of the bucket tooth is prolonged; components and a preparation process of the bucket tooth are changed, so that the high wearing resistance and shock resistance of the bucket tooth are realized.

The invention provides a thermoplastic plastic industrial-grade 3D printing and milling composite processing machine tool which mainly comprises a lathe bed, a milling device and a 3D printing device,wherein the milling device and the 3D printing device are mounted on the lathe bed through an overpass type double-independent gantry structure; the overpass type double-independent gantry structurecomprises a first gantry and a second gantry which are mounted on the lathe bed and can be moved in a reciprocation manner in an X direction, and a double-gantry driving device capable of respectivelydriving the first gantry and the second gantry to make reciprocation movement in the X direction; a milling spindle of the milling device is mounted on a Y1 transverse beam of the first gantry and iscapable of being moved in a Y direction and a Z direction respectively in the reciprocation manner; a nozzle of the 3D printing device is mounted on a Y2 transverse beam of the second gantry and is capable of being moved in the Y direction and the Z direction respectively in the reciprocation manner. By adopting the machine tool, a conventional cast wooden mold manufacturing and machining processcan be changed, the production cycle of a cast wooden mold can be shortened, the production cost can be reduced, the service life of the wooden mold can be prolonged, and the problem that a mold manufacturing company has a great deal of raw material cost can be reduced.
