Abstract
Description
Technical Field
[0001] This application relates to the field of lithium battery separator production technology, and in particular to a waste membrane cleaning device for a lithium battery separator horizontal stretching box. Background Technology
[0002] In the charging and discharging process of lithium-ion batteries, the separator plays a crucial role in separating the positive and negative electrodes to prevent short circuits caused by contact, absorbing sufficient electrolyte, providing ample lithium-ion channels, and providing micropore self-sealing protection. The lithium-ion conductivity of the separator directly affects the overall performance of the lithium-ion battery. The separator's performance determines the battery's interface structure, electrolyte retention, and internal resistance, thus influencing important characteristics such as capacity, cycle performance, charge / discharge current density, and safety. Existing wet-process separator manufacturing methods generally include: batching and casting → biaxial stretching → extraction → transverse stretching → winding and inspection. After extraction and drying, the oil film becomes a microporous separator, which undergoes transverse stretching and finally winding and inspection. The transverse stretching chamber is used to stretch the thin film laterally. During normal production operation, the chamber is at a high temperature. When waste membranes are generated, operators must wear heat-resistant clothing and protective gear to enter the chamber for cleaning. However, entering the high-temperature chamber to clean waste membranes poses safety hazards such as heatstroke, burns, and oxygen deficiency. Utility Model Content

[0023] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.
[0024] like Figure 1 As shown in the figure, this application provides a waste membrane cleaning device for a lithium battery separator horizontal stretching box. The waste membrane cleaning device includes a telescopic component 1 and a claw hook 2. The claw hook 2 is connected to one end of the telescopic component 1. The claw hook 2 is used to grab waste membrane in the lithium battery separator horizontal stretching box. The telescopic component 1 is used to extend the claw hook 2 into the lithium battery separator horizontal stretching box and to retract the claw hook 2 from the lithium battery separator horizontal stretching box.
[0025] This application embodiment is applicable to the cleaning of waste film inside the horizontal pull box of a lithium battery separator production line. After confirming the position of the waste film, the operator adjusts the height of the claw hook. After the claw hook grabs the waste film, it tightens. Then the operator retracts the telescopic component to complete one cleaning operation. Repeating this operation can clean other waste films inside the box.
[0026] like Figure 1 As shown, in some embodiments, the telescopic assembly 1 includes a telescopic rod 11, a reel 12, a pulley 13, and a rope 14; the reel 12 is disposed at one end of the telescopic rod 11, and the pulley 13 is disposed at the other end of the telescopic rod 11; one end of the rope 14 is connected to the reel 12, and the other end is connected to the claw hook 2 via the pulley 13;
[0027] The telescopic rod 11 is used to extend the claw hook 2 into the lithium battery separator horizontal pull box and to retract the claw hook 2 from the lithium battery separator horizontal pull box; the spool 12 is used to control the tension and relaxation of the rope 14; the pulley 13 is used to guide the rope.
[0028] In some embodiments, the telescopic rod 11 comprises multiple stainless steel pipes, the inner diameter of each stainless steel pipe decreasing sequentially from the direction closest to the coil to the direction closest to the pulley.
[0029] In some embodiments, the rope 14 is a stainless steel rope.
[0030] like Figure 2 As shown, in some embodiments, the claw hook 2 includes a plurality of hooks 21, the middle of each hook 21 is bent at a first angle, and the end is raised inward and bent at a second angle.
[0031] In some embodiments, the claw hook 2 further includes a reverse tensioning device for controlling the claw hook 2 to tighten inward when the rope 14 is tightened.
[0032] like Figure 1 As shown, in some embodiments, the waste film cleaning device further includes a support 3, which is disposed at the end of the telescopic component 1 away from the claw hook 2; the support 3 is used to support the telescopic component 1.
[0033] like Figure 1 and Figure 3 As shown, in some embodiments, the waste film cleaning device further includes a counterweight 4, which is connected to the end of the telescopic component 1 away from the claw hook 2, and is used to control the balance of the telescopic component 1.
[0034] Specifically, the telescopic pole 11 can be composed of six stainless steel pipes, each 1500cm long. The inner diameter of the pipes before and after the support 3 is 50mm, and the inner diameters of the pipes from the support 3 to the contact point with the pulley 13 are 50mm, 48mm, 46mm, 44mm, and 42mm, respectively. These different inner diameters facilitate the extension and retraction of the telescopic pole 11. The pulley 13 is a guide wheel with an outer diameter of 60mm, an inner diameter of 30mm, and a width of 15mm, serving as a guide and connection in the middle when the rope 14 is tightened or loosened.
[0035] The stainless steel rope can be 3mm in diameter and has a maximum load capacity of 50kg. The claw hook 2 has a built-in reverse tensioning device; when the rope is tightened, the claw 2 automatically retracts inward to grip the waste film. The claw hook has 5 hooks, each 20cm long, with a 145° angle at the center and a 75° angle at the end, preventing situations where there are too few hooks or the curvature is too small to grip the waste film.
[0036] The support consists of two stainless steel pipes with an inner diameter of 50mm, an outer diameter of 60mm, and a length of 1100mm. The support has a semi-circular stainless steel tray with a length of 10cm, a width of 4cm, and a thickness of 2cm. The support can be adjusted from 0-180°, and the normal working angle of the support is about 70°. The telescopic rod is placed on top of it.
[0037] The counterweight consists of three 20kg weight blocks, with a maximum counterweight of 60kg and a minimum counterweight of 20kg. The counterweight blocks are connected by hooks and wire ropes, and can be assembled and disassembled. The counterweight blocks are located at the very end of the telescopic pole.
[0038] The waste membrane cleaning device for a lithium battery separator horizontal stretching box provided in this application embodiment connects a claw hook to one end of a telescopic component. The claw hook can grab waste membrane inside the lithium battery separator horizontal stretching box. The operator can extend the claw hook into the lithium battery separator horizontal stretching box through the telescopic component. After grabbing the waste membrane, the claw hook can be retracted from the lithium battery separator horizontal stretching box. This allows the operator to clean the waste membrane inside the horizontal stretching box without having to enter the high-temperature box, avoiding the safety hazards of the operator entering the high-temperature box.
