Description

Technical Field

[0001] This application relates to the field of lithium battery separator technology, and in particular to an adjustable separator static elimination device. Background Technology

[0002] The slitting machine is one of the key pieces of equipment in lithium battery separator production. During the slitting process, static electricity is generated due to friction. If the static charge on the separator is too high, the produced separator will exceed the range of static electricity values. Due to friction, peeling, and compression between the separators, different types of charges accumulate on the surface. When this charge accumulates to a certain level, electrostatic adsorption and discharge phenomena will occur. The accumulation and discharge of static charge can cause certain damage to the separator product, such as adhesion, repulsion, and electrostatic breakdown.

[0003] The slitting area has much higher requirements for static elimination of the diaphragm than other areas. Because the static elimination bar's position is fixed and the distance between it and the diaphragm is not adjustable, the static elimination effect can only be adjusted by regulating the air pressure. When changing to different specifications of the roll material, static electricity may not be eliminated from some sections of the roll being wound by the slitting machine. This results in some produced diaphragms consistently failing to meet static electricity requirements. To meet production demands, it is necessary to frequently disassemble and reinstall the static elimination bar and adjust its air pressure, severely reducing production efficiency.

[0031] 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.

[0032] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0035] 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.

[0036] like Figures 1 to 3 As shown in the figure, this application provides an adjustable diaphragm static elimination device, including: a plurality of adjustable static bar assemblies 1, the adjustable static bar assemblies 1 being used to eliminate static electricity in the diaphragm; a mounting beam 2, the plurality of adjustable static bar assemblies 1 being movably mounted on the mounting beam 2; and adjustable supports 3, the adjustable supports 3 being respectively connected to both ends of the mounting beam 2; the adjustable diaphragm static elimination device is used to be mounted on a slitting machine via the adjustable supports 3, and cooperates with the fixed static bars on the slitting machine to achieve full coverage of the winding side station of the slitting machine.

[0037] Excessive static electricity on the diaphragm surface can be harmful to human health and affect the quality of the diaphragm product, causing changes in its physical properties and consequently impacting battery performance. Because the original fixed static bar on the slitting machine has gaps between its components after installation, and the installation position and angle of the static bar are not adjustable, static electricity on some parts of the diaphragm on the winding shaft cannot be completely eliminated. Furthermore, once the slitting machine reaches a certain speed, the performance of the original static bar cannot meet the process requirements for static electricity elimination, and adjustments to the product process can also lead to increased static electricity.

[0038] The adjustable diaphragm static elimination device provided in this application embodiment has multiple adjustable static bar assemblies that are movably mounted on the mounting beam, so that the adjustable static bar assemblies can adjust their mounting positions on the mounting beam, thereby facilitating the adjustable static bar assemblies to cover the gaps between the original fixed static bars of the slitting machine.

[0039] Without the adjustable diaphragm static elimination device provided in this application embodiment, when the diaphragm roll specifications change, the diaphragm roll in the gap portion cannot eliminate static electricity because there are gaps between the original fixed static bar of the slitting machine after installation. Therefore, it is necessary to remove the original fixed static bar and reinstall it in a different position, which is quite cumbersome.

[0040] After installing the adjustable diaphragm electrostatic eliminator provided in this application embodiment, it is only necessary to adjust the installation position of the adjustable electrostatic bar assembly on the installation beam to cover the gap between the original fixed electrostatic bars. By cooperating multiple adjustable diaphragm electrostatic eliminators with the fixed electrostatic bars on the slitting machine, full coverage of the winding side station of the slitting machine can be achieved, meeting the requirements for process electrostatic elimination and improving the efficiency of electrostatic elimination of the diaphragm in the slitting area.

[0041] like Figure 2 As shown, in some embodiments, the adjustable electrostatic bar assembly 1 includes: an electrostatic bar 11 for eliminating static electricity in the diaphragm; and an electrostatic bar support 12, in which the electrostatic bar 11 is installed, and the electrostatic bar support 12 is movably installed on the mounting beam 2.

[0042] In some embodiments, the electrostatic bar 11 is connected to a power supply line, a grounding line, an alarm line, and a start / stop signal line.

[0043] The anti-static bar is connected to two 24V power lines (P24, N24), one grounding line (GND), one alarm line (ALM), and one start / stop signal line (STOP). The start signal for the anti-static bar uses the normally closed contact of an intermediate relay. The adjustable diaphragm anti-static device can be fully automated, automatically starting and stopping, while also providing fault feedback signals.

[0044] In some embodiments, the lengths of the various adjustable electrostatic bar assemblies 1 are not equal.

[0045] The length of the adjustable electrostatic bar assembly can be determined according to the gap between the fixed electrostatic bars of the slitting machine. Since the gap between the fixed electrostatic bars of the slitting machine is usually different, the length of each adjustable electrostatic bar assembly is also not equal. The length of the adjustable electrostatic bar assembly only needs to be able to completely cover the gap between the fixed electrostatic bars of the slitting machine.

[0046] like Figure 3As shown, in some embodiments, the mounting beam 2 has a wire hole 21 for threading the connection line of the electrostatic rod 11.

[0047] In some embodiments, the length of the mounting beam 2 is greater than the total length of the plurality of adjustable electrostatic bar assemblies 1.

[0048] Since the adjustable electrostatic bar assembly needs to be adjusted in position on the mounting beam, the length of the mounting beam needs to be greater than the total length of the multiple adjustable electrostatic bar assemblies, so as to provide space for position adjustment of the multiple adjustable electrostatic bar assemblies.

[0049] like Figure 2 As shown, in some embodiments, the adjustable support 3 is provided with an installation adjustment groove 31, which is used to adjust the installation position of the adjustable diaphragm static elimination device.

[0050] The adjustable diaphragm static eliminator is mounted on the slitting machine via the adjustable support, allowing the device to adjust its position on the slitting machine to ensure the spacing between it and the diaphragm and thus guarantee the static eliminator effect.

[0051] In some embodiments, the adjustable diaphragm electrostatic elimination device is respectively installed between the slitting rollers and between the slitting rollers and the take-up shaft of the slitting machine.

[0052] like Figure 4 and Figure 5 As shown, the two adjustable diaphragm static elimination devices include two static bar supports and four static bars, which are respectively installed between the guide roller 1 and guide roller 2 of the slitting machine and between guide roller 2 and the take-up shaft. This achieves full coverage of the workstation on the take-up side of the slitting machine, which not only avoids the problem of frequently adjusting the position of the fixed static bars of the slitting machine, but also solves the problem of static leakage in some rolls of material on the take-up side of the original slitting machine, so that the diaphragm product achieves the purpose of static elimination.

[0053] The adjustable diaphragm static elimination device provided in this application embodiment can cooperate with the fixed static bar on the slitting machine to achieve full coverage of the winding side station of the slitting machine. This avoids the frequent disassembly and installation of the fixed static bar when the diaphragm roll specifications change. The process will not affect the system operation when adjusting the width of the film roll. It improves production efficiency and saves manpower and time costs while meeting the static elimination requirements of the process.
