[0004] The present invention relates to an electrode mounting unit and an electrode drying apparatus including the electrode mounting unit, and more particularly, to an electrode mounting unit capable of preventing an electrode wound on an electrode roller from unwinding and an electrode drying apparatus including the electrode mounting unit. Background Technology

[0005] Generally, unlike non-rechargeable primary batteries, secondary batteries are rechargeable and dischargeable batteries. Secondary batteries are widely used in high-tech electronic devices such as mobile phones, laptops, and cameras.

[0006] This type of secondary battery is classified into can-type secondary batteries with electrode assemblies built into a metal can and bag-type secondary batteries with electrode assemblies built into a bag. Bag-type secondary batteries include electrode assemblies, electrolyte, and a bag containing the electrode assemblies and electrolyte. Furthermore, the electrode assembly has a structure with multiple electrodes and multiple separators stacked alternately.

[0007] The electrodes are wound into a roller shape and then dried using an electrode drying device to remove residual solvent and moisture. In other words, the electrode drying device according to related technology uses hot air to dry the wound roller-shaped electrodes.

[0008] However, when the electrodes are dried by the electrode drying device, the electrodes wound into a roller shape may be easily unwound and damaged, or process failures may occur due to the unwound electrodes. Summary of the Invention

[0009] Technical issues

[0010] The present invention has been made to solve the above-mentioned problems. The object of the present invention is to provide an electrode mounting unit and an electrode drying apparatus including the electrode mounting unit. The electrode mounting unit includes an anti-unwinding member for preventing the unwinding of the electrode wound into a roller shape, so as to stably mount and dry the electrode, thereby preventing process failures in advance.

[0011] Technical solution

[0012] To achieve the above objectives, the electrode mounting unit according to a first embodiment of the present invention includes: a mounting member comprising a horizontal plate, a vertical plate disposed on the top surface of the horizontal plate, and a shaft fixed to the vertical plate, wherein an electrode roller is assembled to the shaft to mount the electrode roller; and an anti-unwinding member disposed between an electrode wound on the electrode roller and the horizontal plate to support the electrode wound on the electrode roller, thereby preventing the electrode wound on the electrode roller from unwinding.

[0013] The top surface of the anti-unwinding member supporting the electrode can be formed as a curved surface, and the curved surface has the same radius of curvature as the electrode wound on the electrode roller.

[0014] A hook-shaped protrusion may be formed at one end of the curved surface, the hook-shaped protrusion hooking and supporting the electrode wound on the electrode roller.

[0015] One side surface of the anti-winding member may be formed as an inclined surface.

[0016] A handle portion may be formed on the other side surface of the anti-winding member.

[0017] The anti-winding component may be made of synthetic resin with elastic restoring force.

[0018] An electrode drying apparatus according to a second embodiment of the present invention includes: a mounting unit on which an electrode roller is mounted and an electrode is wound around the electrode roller; and a drying chamber that houses the mounting unit to dry the electrode wound around the electrode roller, wherein the mounting unit includes a mounting member and an anti-unwinding member, the mounting member including a horizontal plate, a vertical plate disposed on the top surface of the horizontal plate and a shaft fixed to the vertical plate, the electrode roller being assembled to the shaft to mount the electrode roller, and the anti-unwinding member being disposed between the electrode wound around the electrode roller and the horizontal plate to support the electrode wound around the electrode roller, thereby preventing the electrode wound around the electrode roller from unwinding.

[0019] In the electrode mounting unit according to the third embodiment of the present invention, the bottom surface of the anti-unwinding member can be formed as a horizontal surface, wherein an unevenness for preventing slippage can be formed on the horizontal surface.

[0020] In the electrode mounting unit according to the fourth embodiment of the present invention, an unevenness is formed on the curved surface of the anti-unwinding member.

[0021] Beneficial effects

[0022] First: The electrode mounting unit of the present invention may include a mounting member and an anti-unwinding member. An electrode roller, in which the electrode is wound into a roller shape, is mounted on the mounting member. The anti-unwinding member supports the electrode wound on the electrode roller mounted on the mounting member, thereby preventing the electrode wound on the electrode roller from unwinding.

[0023] Second: In the electrode mounting unit of the present invention, the top surface of the anti-unwinding member may have a curved surface, the curved surface having the same radius of curvature as the electrode wound on the electrode roller. Therefore, the adhesion between the electrode and the anti-unwinding member can be increased, thereby stably supporting the electrode and effectively preventing the electrode wound on the electrode roller from unwinding.

[0024] Third: Hook-shaped protrusions can be formed on the curved surface of the anti-unwinding member of the present invention, which hook and support one side of the electrode wound on the electrode roller. Therefore, the attachment position between the electrode wound on the electrode roller and the anti-unwinding member can be easily adjusted.

[0025] Fourth: One side surface of the anti-unwinding member can be formed as an inclined surface. Therefore, the anti-unwinding member can be easily inserted between the electrode wound on the electrode roller and the mounting member. That is, when the space between the electrode wound on the electrode roller and the mounting member is less than the thickness of the anti-unwinding member, the anti-unwinding member can be easily inserted between the electrode wound on the electrode roller and the mounting member when the inclined surface is closely attached to the bottom surface of the mounting member to tilt the anti-unwinding member.

[0026] Fifth: The handle portion may be formed on the other side surface of the anti-unwinding member of the present invention. Therefore, the anti-unwinding member can be easily inserted between the electrode wound on the electrode roller and the mounting member, or the anti-unwinding member can be easily removed.

[0027] Sixth: Unevenness can be formed on the bottom surface of the anti-unwinding component to prevent it from sliding and thus prevent movement. Therefore, the electrode wound on the electrode roller can be stably supported and the electrode unwinding can be prevented.

[0028] Seventh: Unevenness can be formed on the curved surface of the anti-unwinding component. Therefore, the electrode wound on the electrode roller and the anti-unwinding component can be supported in multiple sections to effectively prevent electrode unwinding.

[0029] Eighth: The electrode drying device may include an electrode mounting unit and a drying chamber to stably mount and dry the electrodes, thereby preventing process failures in advance. Attached Figure Description

[0038] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, enabling those skilled in the art to readily implement the technical concept of the present invention. However, the present invention may be implemented in different forms and should not be construed as limited to the embodiments described herein. In the drawings, any elements unnecessary for describing the present invention will be omitted for clarity, and like reference numerals denote like elements.

[0039] [Electrode mounting unit according to the first embodiment of the present invention]

[0040] like Figure 1 As shown in the figure, the electrode mounting unit 110 according to the first embodiment of the present invention includes a mounting member 111 and an anti-unwinding member 112. An electrode roller 10 with an electrode 1 wound on it is mounted on the mounting member 111, and the anti-unwinding member 112 supports the electrode 1 to prevent the electrode 1 of the electrode roller 10 mounted on the mounting member 111 from unwinding.

[0041] The electrode roller 10 includes a cylindrical winding portion 11 and a plate-shaped support portion 12. The electrode 1 is wound on the winding portion 11, and the center of the winding portion 11 has a mounting hole. The support portions 12 are respectively provided at both ends of the winding portion 11 to support the two side surfaces of the electrode wound on the winding portion 11. The winding portion 11 and the support portion 12 are integrated with each other.

[0042] Mounting component 111 includes a horizontal plate 111a, a vertical plate 111b disposed on the top surface of the horizontal plate 111a, and a shaft 111c fixed to the vertical plate 111b, wherein the electrode roller 10 is mounted on the shaft 111c to mount the electrode roller 10.

[0043] Here, the horizontal plate 111a and the vertical plate 111b can be connected to each other in an "L" shape. Therefore, the space between the horizontal plate 111a and the vertical plate 111b can be utilized effectively.

[0044] Specifically, the horizontal plate 111a and the vertical plate 111b may be made of the same material. The thickness of the horizontal plate 111a may be greater than the thickness of the vertical plate 111b to prevent the vertical plate 111b from collapsing due to its own weight.

[0045] Furthermore, the shaft 111c may have a structure that adjusts its position on the vertical plate 111b along a direction toward or away from the horizontal plate 111a. Therefore, the gap between the shaft 111c and the horizontal plate 111a can be adjusted, thus allowing the installation of electrode rollers 10 of various sizes.

[0046] For example, such as Figure 2 As shown, shaft 111c includes an insertion part 111c-1 and a bolt 111c-3. The insertion part 111c-1 is inserted into one side of an elongated hole 111b-1 formed in a vertical plate 111b along the direction of the horizontal plate 111a. The bolt 111c-3 includes a support piece 111c-2 disposed on the other side of the elongated hole 111b-1 and coupled to the insertion part 111c-1 to fix the shaft 111c.

[0047] In other words, bolt 111c-3 can be released or tightened to allow shaft 111c to rise or fall within elongated hole 111b-1. Therefore, the gap between shaft 111c and horizontal plate 111a can be easily adjusted.

[0048] The mounting member 111 having the above-described structure may include a horizontal plate 111a, a vertical plate 111b, and a shaft 111c to easily mount the electrode roller 10 on which the electrode 1 is wound.

[0049] like Figure 3 and 4 As shown, the anti-unwinding member 112 is mounted on the mounting member to prevent the electrode wound on the electrode roller from unwinding. The anti-unwinding member 112 is inserted between the electrode 1 wound on the electrode roller 10 and the horizontal plate 111a to support the electrode 1 wound on the electrode roller 10, thereby preventing the electrode 1 wound on the electrode roller 10 from unwinding.

[0050] In other words, the electrode 1 wound on the electrode roller 10 can be unwound due to restoring force. Here, the anti-unwinding member 112 can be pressed between the electrode 1 wound on the electrode roller 10 and the horizontal plate 111a to press and support the electrode 1 wound on the electrode roller 10, thereby preventing the electrode 1 wound on the electrode roller 10 from unwinding.

[0051] Specifically, the top surface of the electrode 1 wound on the support electrode roller 10 of the anti-unwinding member 112 is formed as a curved surface 112a, and the curved surface 112a has the same radius of curvature as the electrode 1 wound on the electrode roller 10. That is, the top surface of the anti-unwinding member 112 can be formed as a curved surface 112a to increase the adhesion area between the electrode 1 and the curved surface 112a, thereby effectively preventing the electrode 1 wound on the electrode roller 10 from unwinding.

[0052] Hook-shaped protrusions 112b are formed at one end 112a-1 of the curved surface 112a, so that the electrode wound on the electrode roller 10 is hooked and supported, thereby preventing the electrode 1 wound on the electrode roller 10 from separating through one end 112a-1 of the curved surface 112a, and in particular, the attachment portion between the electrode 1 wound on the electrode roller 10 and the anti-unwinding member 112 can be easily adjusted.

[0053] One side surface of the anti-unwinding member 112 can be formed as an inclined surface 112c, and due to the inclined surface 112c, the anti-unwinding member 112 can be easily inserted between the electrode 1 wound on the electrode roller 10 and the mounting member 111. That is, as Figure 5 As shown, when the inclined surface of the anti-unwinding member 112 is tightly attached to the mounting member 111, the anti-unwinding member 112 can be easily inserted between the electrode 1 wound on the electrode roller 10 and the mounting member 111.

[0054] like Figure 4 As shown, in the curved surface 112a, the other end 112a-2 of the inclined surface 112c in the direction of the electrode 1 can be higher than the end 112a-1 of the hook-shaped protrusion 112b. That is, due to the formation of the hook-shaped protrusion 112b, the electrode 1 can be stably supported at one end 112a-1 of the curved surface 112a. However, since the other end 112a-2 of the curved surface 112a does not have a structure to support the electrode 1, the other end 112a-2 can be formed to be higher than the first end 112a-1 to prevent the electrode 1 supported on the curved surface 112a from separating in the direction of the other end 112a-2.

[0055] In more detail, refer to Figure 4 The height α from the top surface of the horizontal plate 111 to the other end 112a-2 of the curved surface 112a can be greater than the height β from the top surface of the horizontal plate 111 to one end 112a-1 of the curved surface 112a.

[0056] A handle portion 112d is formed on the other side surface of the anti-unwinding member 112. The anti-unwinding member 112 can be tilted by the handle portion 112d, or the anti-unwinding member 112 can be easily inserted between the electrode 1 wound on the electrode roller 10 and the mounting member 111, or removed by the handle portion 112d. Moreover, when forming the anti-unwinding member 112, the handle portion 112d can be integrated with the anti-unwinding member 112 to improve manufacturing convenience.

[0057] Specifically, the other side surface of the anti-unwinding member 112 is formed as an inclined surface corresponding to the inclined surface 112c formed on one side surface of the anti-unwinding member 112, and the handle portion 112d is formed on this inclined surface. That is, both side surfaces of the anti-unwinding member 112 can be formed as inclined surfaces with an approximately "V" shape. Therefore, the surface area of ​​the curved surface 112a formed on the top surface of the anti-unwinding member 112 can be significantly increased to more stably support the electrode 1 wound on the electrode roller 10.

[0058] The anti-unwinding member 112 is made of a synthetic resin with elastic recovery. In particular, the anti-unwinding member 112 can be made of Viton to elastically support the electrode 1 wound on the electrode roller 10, thereby preventing damage to the electrode 1. Viton can be fluororubber and has good heat resistance, oil resistance and chemical resistance to effectively prevent damage to the electrode 1.

[0059] Therefore, the electrode mounting unit 110 with the above-described structure according to the first embodiment may include a mounting member 111 and an anti-unwinding member 112 to stably mount the electrode roller 10 on which the electrode 1 is wound and to effectively prevent the electrode 1 wound on the electrode roller 10 from unwinding.

[0060] In the following description of another embodiment of the present invention, configurations having the same structure and function as those in the above embodiment are given the same reference numerals in the drawings, and therefore repeated descriptions will be omitted.

[0061] [Electrode drying apparatus according to a second embodiment of the present invention]

[0062] like Figure 6 As shown, the electrode drying apparatus 100 according to the second embodiment of the present invention is configured to dry an electrode wound on an electrode roller and includes a mounting unit 110 and a drying chamber 120. The electrode roller 10 with the electrode 1 wound on it is mounted on the mounting unit 110, and the drying chamber 120 accommodates the mounting unit 110 to dry the electrode 1 wound on the electrode roller 10.

[0063] The mounting unit 110 includes a horizontal plate 111, a vertical plate 112 disposed on the top surface of the horizontal plate 111, and a shaft 113 fixed to the vertical plate 112, wherein the electrode roller 10 is assembled to the shaft 113 to mount the electrode roller 10.

[0064] Here, the mounting unit 110 has the same structure and function as the electrode mounting unit 110 of the aforementioned first embodiment of the present invention, therefore, its detailed description will be omitted.

[0065] The drying chamber 120 has a receiving space for accommodating the mounting unit 110, and hot air or heat is applied to the electrode roller 10 mounted on the mounting unit 110 to dry the electrode 1 wound on the electrode roller 10.

[0066] Here, the electrode 1 wound on the electrode roller 10 is supported by the anti-unwinding member of the mounting unit 110 so that the electrode 1 wound on the electrode roller 10 can be prevented from unwinding even if hot air is applied directly to the electrode 1.

[0067] Therefore, the electrode drying apparatus 100 according to the second embodiment of the present invention can prevent the electrode 1 wound on the electrode roller 10 from unwinding and stably dry the electrode 1 wound on the electrode roller 10.

[0068] [Electrode mounting unit according to a third embodiment of the present invention]

[0069] In the electrode mounting unit according to the third embodiment of the present invention, such as Figure 7 As shown, the bottom surface of the anti-rewinding member 112 supported on the horizontal plate 111 can be set as a horizontal surface 112e to stably place the anti-rewinding member 112 on the horizontal plate 111.

[0070] Specifically, unevenness can be formed on the horizontal surface 112e to prevent slippage, thereby preventing the anti-unwinding member 112 from moving on the horizontal plate 111. Therefore, the anti-unwinding member 112 can stably support the electrode 1 wound on the electrode roller 10 to prevent the electrode 1 from unwinding.

[0071] [Electrode mounting unit according to the fourth embodiment of the present invention]

[0072] In the electrode mounting unit 110 according to the fourth embodiment of the present invention, such as Figure 8As shown, an unevenness can be formed on the curved surface 112a of the anti-unwinding member 112, so that the electrode 1 wound on the electrode roller 10 and the curved surface 112a of the anti-unwinding member 112 can be supported in multiple segments to effectively prevent the electrode 1 from unwinding, and in particular, to prevent the electrode 1 wound on the electrode roller 10 and supported on the curved surface 112a from sliding. In particular, an unevenness can be formed on the curved surface 112a to form a channel between the electrode 1 and the curved surface 112a, thereby stably drying the electrode 1 disposed on the curved surface 112a.

[0073] Therefore, the scope of this invention is defined by the appended claims rather than by the foregoing description and the exemplary embodiments described herein. Various modifications made within the meaning of the claims and their equivalents are considered to fall within the scope of this invention.
