The utility model relates to the technical field of metal packaging shells, and discloses a convenient-to-assemble metal packaging shell which comprises a lower shell body, a matching groove is formed in the inner wall of the top end of the lower shell body, a fixing frame is fixedly clamped in the matching groove through a clamping assembly, and an upper shell cover is fixedly connected to the top of the fixing frame. The clamping assembly comprises a clamping column penetrating through the lower shell, a moving groove is formed in the position, located on the outer side of the clamping column, of the lower shell, a moving block is slidably arranged in the moving groove and fixedly connected with the clamping column, and a spring is arranged between the moving block and the side wall of the moving groove. Clamping grooves matched with the clamping columns are formed in the outer wall of the fixing frame; the movable block can be pushed through the spring to drive the clamping column to extend into the clamping groove, fixed connection of the upper shell cover and the lower shell is achieved, on the contrary, the upper shell cover and the lower shell can be separated by pulling the clamping column, and the device assembling convenience is improved.

This invention relates to the field of lithium-ion battery applications and discloses a top-sealing process for a pouch battery. The process includes: placing the top sealing edge of the pouch battery to be packaged between an upper sealing head and a lower sealing head of a top-sealing device; driving the upper sealing head to close with the lower sealing head; hot-pressing the positive tab region of the pouch battery using a first set of packaging parameters; simultaneously hot-pressing the negative tab region of the pouch battery using a second set of packaging parameters; and hot-pressing other regions besides the positive and negative tab regions using a third set of packaging parameters. The first set of packaging parameters includes a first packaging temperature and a first packaging time, and the second set of packaging parameters includes a second packaging temperature and a second packaging time. The first packaging temperature is higher than the second packaging temperature, and the first packaging time is shorter than the second packaging time.

The utility model discloses a display panel mother board, a display panel and a display device, and relates to the technical field of display. The display panel mother board comprises a mother board substrate, a plurality of display panels located in a plurality of panel areas, a test element group located in an invalid area and a second supporting structure located in the invalid area. The second sub-display area of the display area of the display panel is provided with a first supporting structure. Therefore, the PT formed by material falling due to relative displacement between the mask and the first supporting structure in the evaporation process is closer to the second sub-display area. The part, located in the second sub-display area, of the packaging film layer is thicker, so that the PT can be prevented from puncturing the packaging film layer, the packaging effect of the packaging film layer is ensured, and the yield and the display effect of the display panel are improved. Moreover, the first supporting structure and the second supporting structure share the mask used in the supporting evaporation process, so that the supporting effect on the mask can be ensured, and the preparation yield of the display panel mother board is improved.

This utility model discloses a bottle outlet track for a filling and sealing machine, belonging to the technical field of filling and sealing machines. It includes a track body comprising multiple frames arranged in a linear array. Adjacent frames are fixed to each other on both sides by assembly plates. A conveyor belt is installed inside the track body. Mounting plates are fixedly installed on both sides of the track body, each mounting plate being L-shaped. A correction component is provided between the two mounting plates. A support frame is fixedly installed at the bottom of the track body, and a mounting frame is fixedly installed at the top of the track body, located between the support frame and the mounting plates. A stop component is provided inside the mounting frame, and a limiting component is provided inside the support frame. In this utility model, the limiting component at the top of the track body drives a double-threaded screw to rotate via a geared motor, thereby causing two support blocks, along with the column, connecting block, and clamping plate, to move. The cooperation of the two clamping plates helps to limit and position the bottles to be sealed, thus maintaining the sealing effect of the equipment.
