[0020] The following further describes the present application in detail with reference to the drawings and specific embodiments.

[0021] As Figures 1 to 5As shown in the figure, a feeding device for a button battery separator paper includes a frame 1, an assembly conveying mechanism 41, a separator paper roll placing mechanism 42, and a punching and pressing mechanism 43 arranged on the frame 1; the assembly conveying mechanism 41 is connected to the lithium strip assembly conveying mechanism 32 and is used for transferring and conveying the die sleeve; the separator paper roll placing mechanism 42 is used for installing the separator paper roll; the punching and pressing mechanism 43 is used for punching the separator paper roll and pressing the punched separator paper onto the lithium strip in the shell.

At the same time, the automated assembly can ensure the assembly consistency and assembly quality.

[0022] As Figure 1 and Figure 2As shown, the assembly conveying mechanism 41 includes a diaphragm paper assembly conveying total drive assembly and a number of sequentially connected rotary conveying assemblies 411. The diaphragm paper assembly conveying total drive assembly is used to drive all the rotary conveying assemblies 411 to rotate synchronously. The diaphragm paper assembly conveying total drive assembly is a conventional motor-gear matching structure. Each rotary conveying assembly 411 includes a conveying rotary gear 414 at the bottom, a conveying connecting shaft 415 in the middle, and a conveying rotary disk 416 at the top. The conveying rotary gear 414 is in transmission connection with the total gear on the diaphragm paper assembly conveying total drive assembly. The conveying rotary disk 416 rotates synchronously with the conveying rotary gear 414 through the conveying connecting shaft 415. A diaphragm paper assembly conveying fixed sleeve 417 is sleeved outside the conveying connecting shaft 415, and the diaphragm paper assembly conveying fixed sleeve 417 is fixedly arranged on the frame 1. A diaphragm paper assembly conveying support disk 418 is arranged at the top of the diaphragm paper assembly conveying fixed sleeve 417. The diaphragm paper assembly conveying support disk 418 is located below the conveying rotary disk 416, so as to support the die sleeve and prevent the die sleeve from falling. A plurality of conveying notches 419 are arranged at intervals on the outer peripheral wall of the conveying rotary disk 416. The conveying notches 419 are arc-shaped and match the outer peripheral wall of the die sleeve. A diaphragm paper assembly conveying baffle 4181 is arranged on the diaphragm paper assembly conveying support disk 418 at the outer periphery of the conveying rotary disk 416. The diaphragm paper assembly conveying baffle 4181 can prevent the die sleeve from separating from the conveying rotary disk 416 during conveying. The automatic conveying is realized by the rotation of the conveying rotary disk 416, greatly improving the conveying efficiency. The conveying rotary gears 414 on two adjacent rotary conveying assemblies 411 are sequentially meshed with each other, so that the diaphragm paper assembly conveying total drive assembly can drive all the rotary conveying assemblies 41 to rotate synchronously, and the assembly conveying mechanism 41 realizes the function of connecting and conveying.

This mechanism facilitates the placement and conveying of the diaphragm paper roll. Under the action of the diaphragm paper auxiliary roller 474 and the paper feeding distance control component, the diaphragm paper is ensured to be tightly connected, and accurate and stable conveying can be realized. At the same time, the friction force between the two diaphragm paper tensioning guide rollers 473 can ensure that the length of the diaphragm paper conveyed each time is uniform, ensuring the consistency of conveying, so as to facilitate better press-fitting.

[0025] As Figure 3 and Figure 4As shown in the figure, the punching component includes a punching bracket 430, a punching driving member 437, a punching positioning plate 438, and two punching rods 439. The punching driving member 437 realizes linear driving through a cylinder, an electric cylinder, or an oil cylinder.

The diaphragm paper strip can be limited through the diaphragm paper strip conveying space 4312, and punching is convenient, ensuring punching accuracy. Two diaphragm paper punching holes are arranged on the diaphragm paper conveying and positioning plate 4311; the punching bracket 430 is arranged on the pressing positioning plate 434, the punching driving member 437 is arranged vertically on the punching bracket 430, the telescopic rod of the punching driving member 437 passes through the punching bracket 430 and is fixedly connected to the punching positioning plate 438. The punching rods 439 are arranged vertically on the bottom surface of the punching positioning plate 438, and the punching rods 439 are aligned with the diaphragm paper punching holes. The lower ends of the punching rods 439 pass through the pressing positioning plate 434 and are located in the diaphragm paper strip conveying space 4312, and punching heads 4391 are connected to the lower ends of the punching rods 439. Through the punching and pressing mechanism 43, the punching can be conveniently pressed into the shell, and the diaphragm paper can be evenly pressed onto the lithium strip in the shell through the pressing component. When punching and pressing are performed, the pressing component and the punching component are processed simultaneously, which can ensure that punching and pressing are processed simultaneously at different stations, further improving the processing efficiency.

[0026] As Figure 5 shown in the figure, a liquid injection component 46 is arranged on the conveyor belt fixing bracket of the diaphragm paper assembly conveyor belt component 45; the liquid injection component 46 is used for performing liquid injection operation after pressing, so as to facilitate the subsequent installation of the negative electrode sheet. The liquid injection component 46 includes a liquid injection bracket 461 and two liquid injection joints 462; the liquid injection bracket 461 is arranged on the conveyor belt fixing bracket, the liquid injection joints 462 are arranged vertically on the liquid injection bracket 461, and the liquid injection joints 462 are located above the conveyor belt fixing bracket.

[0027] As Figures 1 to 5As shown, when the device works, the housing and the die sleeve assembly are conveyed onto the rotary conveying assembly 411. The transfer of the housing and the die sleeve assembly is realized through the connection and conveyance between the rotary conveying assemblies 411. The adjacent rotary conveying assemblies 411 are synchronously rotated through the meshing of two conveying rotary gears 414, so that the housing and the die sleeve assembly on the adjacent two conveying rotary discs 416 can be connected and transferred. In this embodiment, punching and pressing are performed on the second rotary conveying assembly 411. First, the diaphragm paper roll is sleeved on the diaphragm paper discharge disc 422, and then one end of the diaphragm paper roll is wound around the diaphragm paper auxiliary roller 474, passes through the diaphragm paper tape conveying space 4312, and is fixed to the diaphragm paper collecting disc 423 between the diaphragm paper active bracket 471 and the diaphragm paper driven bracket 472, so that the diaphragm paper tape is circulated and conveyed. The diaphragm paper tape is conveyed by the rotation of one of the diaphragm paper tensioning guide rollers 473. The punching driving member 437 (cylinder) on the punching assembly drives two punching rods 439 to punch the diaphragm paper at two workstations at the same time, break through the diaphragm paper tape and preliminarily press the broken part of the diaphragm paper into the housing. Then, the housing with the diaphragm paper is conveyed to the subsequent workstations of the second rotary conveying assembly 411. The pressing driving member 433 (cylinder) on the pressing assembly drives two diaphragm paper pressing rods 4361 to press down, and presses the diaphragm paper flat in the housing. At the same time, the pressing spring 4363 can play a good buffering role during pressing to prevent the housing from being damaged. During pressing, the punching assembly punches two other housings at the same time, which can ensure that punching and pressing are processed at different workstations simultaneously, further improving the processing efficiency. After processing, it is conveyed to the subsequent rotary conveying assembly 411, and the two liquid injection joints 462 on the liquid injection assembly 46 are used to perform liquid injection processing on the housing with the diaphragm paper, eliminating the need for manual liquid injection and greatly improving the assembly efficiency of the diaphragm paper.
