Description

Secondary cell battery insulation film automatic attachment system

[0001] The present invention relates to an automatic secondary battery insulation film attachment system capable of attaching an insulation film at an accurate location with a predetermined quality, departing from the conventional method of attaching an insulation film by hand, for insulating a secondary battery pack used in a train or electric vehicle.

[0002] Figure 1 is a photograph of an insulating film assembly used in the present invention.

[0003] Recently, with the development of technology and increasing demand for electric vehicles, the demand for secondary batteries as an energy source is rapidly increasing.

[0004] Battery packs such as lithium secondary batteries have a risk of short circuits when exposed to high temperatures due to contact between the positive and negative electrodes. In addition, if a large current flows in a short period of time due to overcharging, internal / external short circuits, or local crush, the battery may be heated by heat generation, posing a risk of fire or explosion.

[0005] In addition, as charging and discharging are repeated, the volume of the battery pack expands due to gas generation caused by side reactions between the electrode material and electrolyte, and this also leads to safety issues such as explosion.

[0006] Insulating film is what solves this phenomenon.

[0007] In the past, to attach the insulating film to the battery pack, it had to be attached one by one by a person, just like attaching film to a smartphone.

[0008] Therefore, it was not only difficult to maintain the desired quality, but also the defect rate was high and it took a lot of time, so the development of an improvement plan was required.

[0009] Accordingly, the inventor of the present invention has developed an automatic secondary battery insulation film attachment system that can attach an insulation film to an accurate location with a predetermined quality, thereby significantly reducing the defect rate and process time, departing from the existing method of attaching an insulation film by hand for insulating secondary battery packs used in trains or electric vehicles.

[0010] The present invention is proposed to solve the above-mentioned problems of the prior art.

[0011] The purpose is to insulate secondary battery packs used in trains or electric vehicles, and to provide an automatic secondary battery insulation film attachment system that can attach insulation film to an accurate location with a certain quality, significantly reducing the defect rate and process time, rather than the existing method of attaching insulation film by hand.

[0012] In order to solve the above-mentioned technical problem, the present invention is to attach the insulating film (13) to a battery pack (20) from an insulating film assembly (10) including an insulating film (13) and a release paper (15) attached to the insulating film (13).

[0013] A secondary battery insulation film automatic attachment system is provided, characterized in that the insulation film (13) separated from the insulation film assembly (10) is moved by a multi-axis flexible robot arm (100) and attached to the battery pack (20).

[0014] And, an insulating film suction part (200) is installed at one end of the above robot arm (100).

[0015] A secondary battery insulation film automatic attachment system is provided, characterized in that the insulation film suction part (200) vacuum-sucks the insulation film (13).

[0016] An insulating film assembly cartridge (300) in which a plurality of the above insulating film assemblies (10) are vertically stacked is installed;

[0017] When the insulating film assembly (10) located at the top of the insulating film assembly cartridge (300) is moved by being vacuum-sucked by the insulating film suction unit (200),

[0018] A secondary battery insulation film automatic attachment system is provided, characterized in that the insulation film assembly (10) located underneath moves upward and is loaded.

[0019] According to the present invention, for the insulation of secondary battery packs used in trains or electric vehicles, a secondary battery insulation film automatic attachment system is provided, which, unlike the existing method of attaching insulation film by manpower, attaches insulation film at an accurate location with a predetermined quality, thereby significantly reducing the defect rate and process time.

[0036] It is characterized in that the insulating film assembly (10) located underneath moves upward and is loaded.

[0041] An insulating film assembly cartridge (300) in which a plurality of insulating film assemblies (10) are vertically stacked;

[0042] A release paper separator (400) that separates the release paper (15) from the insulating film assembly (10);

[0043] A position measuring unit (500) that measures whether the insulating film (13) from which the heteromorphic paper (15) is separated is maintained in the correct position and absorbed by the insulating film absorbing unit (200);

[0044] An insulating film attachment part (600) that attaches an insulating film (13) to a battery pack (20);

[0045] It consists of including.

[0046] Figure 3 illustrates an insulating film suction unit installed on one end of a robot arm in the present invention.

[0047] Figure 5 illustrates a state in which an insulating film assembly is absorbed into an insulating film absorption portion in the present invention.

[0048] As shown,

[0049] The above insulating film suction part (200) is precisely controlled by a control part (not shown) and is attached to a multi-axis flexible robot arm (100) so that it can move up, down, left, right, and rotate, and can move to any position.

[0050] As shown in Fig. 3, a plurality of suction ports are formed on the bottom surface of the insulating film suction part (200) and vacuum is sucked through the suction ports.

[0051] As shown in Fig. 5, the entire surface of the insulating film (13) of the insulating film assembly (10) is firmly absorbed onto the entire bottom surface of the insulating film absorbing portion (200).

[0052] FIG. 4 illustrates an insulating film assembly cartridge in which a plurality of insulating film assemblies are vertically stacked according to the present invention.

[0053] In the above insulating film assembly cartridge (300), a plurality of the above insulating film assemblies (10) are vertically stacked.

[0054] When the insulating film assembly (10) located at the top is vacuum-sucked by the insulating film suction unit (200) as shown in Fig. 5 and moves to the release paper separating unit (400),

[0055] The insulating film assembly (10) located below is loaded by moving upward like a bullet being loaded.

[0056] Figure 6 illustrates a release paper separator that separates release paper from an insulating film assembly.

[0057] Figures 7 and 8 sequentially illustrate the process of separating the release paper in the release paper separating section of the prototype of the present invention.

[0058] If the insulating film adsorption part (200) that adsorbs the insulating film assembly (10) on the lower surface is located on the upper part of the release paper separating part (400),

[0059] The protrusion (17) of the release paper (15) attached to the lower part of the above insulating film assembly (10) is held by the clip (410) and separated downward.

[0060] The above clip (410) is mounted on a rail that can move in two axes: up and down and forward and backward.

[0061] As shown by the red dotted arrow in Fig. 6, move diagonally downward while holding the protrusion (17).

[0062] Therefore, the boundary between the release paper (15) attached to the insulating film (13) and the separated release paper (15) maintains an acute angle.

[0063] It has the characteristic of being easy to separate the release paper (15) from the insulating film (13).

[0066] Below the above position measuring unit (500), an insulating film adsorption unit (200) is positioned to have the insulating film (13) adsorbed on the upper surface so that the insulating film (13) from which the release paper (15) is separated faces upward.

[0067] Next, the video recording unit (510) records whether the insulating film (13) is properly adhered to the insulating film adsorption unit (200).

[0068] During the process of vacuum suction of the insulating film assembly (10) by the insulating film suction part (200) or the process of separating the release paper (15), the position of the insulating film (13) absorbed by the insulating film suction part (200) may slightly change.

[0069] The image captured by the above control unit (not shown) is analyzed to accurately measure and store the changed position of the insulating film (13).

[0070] FIG. 10 is a drawing illustrating an insulating film attachment portion in the present invention. Referring to FIG. 2, the process of attaching an insulating film to a battery pack at the insulating film attachment portion will be described.

[0071] The insulating film adsorption unit (200) that has absorbed the insulating film (13) is moved from the position measurement unit (500) to the insulating film attachment unit (600) by the robot arm (100).

[0072] A battery pack (20) is mounted on the above insulating film attachment portion (600).

[0073] An insulating film adsorption part (200) is located on the upper part of the above battery pack (20) and has an insulating film (13) adsorbed on the lower surface.

[0074] Next, the control unit (not shown) lowers the insulating film adsorption unit (200) that has the insulating film (13) adsorbed on the lower surface, and makes fine adjustments in consideration of the changed position of the insulating film (13) to attach the insulating film (13) to the upper portion of the battery pack (20).

[0075] The present invention is for the insulation of a secondary battery pack used in a train or electric vehicle, and has the characteristic of providing an automatic secondary battery insulation film attachment system that can attach an insulation film to an accurate location with a predetermined quality, thereby significantly reducing the defect rate and process time, rather than the existing method of attaching an insulation film by manpower.

[0076] Although the present invention has been described with reference to preferred embodiments as mentioned above, various modifications and variations are possible within the scope of the present invention, and it can be used in various fields.

[0077] Therefore, the claims of the present invention include modifications and variations that fall within the true scope of the present invention.
