Description

[Technical field]

[0001] The present invention relates to an automatic cleaning device for pattern jigs after laser notching, and in particular to a means for removing contaminants such as fumes and particles that are generated on the supporting part of the pattern jig due to high temperatures when positively coating aluminum foil and negatively coating copper foil, and cutting the uncoated plain part with a pattern jig supported by the pattern jig with a laser. The device is equipped with two pattern jigs on a single square rotor, and the rotor is rotated 90 degrees alternately upwards and downwards, and a brush is moved left and right above and below to periodically clean the uncoated part, enabling continuous operation for cutting the uncoated part. [Background technology]

[0002] In general, secondary batteries are becoming an essential factor for future life as the demand for environmentally friendly alternative energy sources increases with the depletion of fossil fuels, and concerns about environmental pollution grow.

[0003] The electrodes for forming the electrode assembly are manufactured in such a manner that an active material is applied to a portion of the electrodes and the remaining portion of the electrodes is not applied with the active material, thereby exposing the electrode body.

[0004] In this way, the exposed portions of the electrode body are processed to serve as electrode terminals for connecting the positive and negative electrodes to the outside when constructing an electrode assembly. To enable such processing, the electrodes are formed by coating an active material on a thin plate conductor constituting the electrode body, and are in a processed, undivided state.

[0005] Typically, a notching device is a device that cuts a portion of an exposed portion of an electrode and a coating portion on which an active material is applied to form a terminal portion, and the terminal portion is formed by cutting a portion of the exposed portion by punching or using a laser.

[0006] That is, the notching process is a process of cutting off the remaining parts of the cut electrodes after the slitting process, i.e., the blank parts where the positive / negative active materials are not applied, while leaving a part for grounding the tab. The notching process has the characteristic that the outline does not form a closed curve by cutting the desired shape from the edge of the material.

[0007] Conventionally, notching devices using punching were mainly used, but recently, the use of notching devices using lasers, which cause less damage to electrodes and enable more efficient production than punching, has been increasing.

[0008] Conventionally, when cutting blank areas using a laser, that is, when positive and negative electrode coating is performed on an aluminum foil and then the uncoated blank areas are cut, the blank areas are supported by a pattern jig and cut by a laser. At this time, the high heat of the laser causes fumes and particles to adhere to the supporting part of the pattern jig, causing contamination, and thus making it impossible to perform continuous blank cutting operations.

[0010] The present invention has been made to solve the above-mentioned conventional drawbacks, and an object of the present invention is to enable continuous laser cutting of uncoated areas by removing fumes and particles generated at the supporting part of the pattern jig when positively coating aluminum foil and negatively coating copper foil, and cutting the uncoated areas by laser while supporting the uncoated areas by the pattern jig. The present invention provides an automatic pattern jig cleaning device after laser notching, in which when the first pattern jig of two pattern jigs (first and second pattern jigs) is rotated upward by 90 degrees, the first brush moves left and right to clean the first pattern jig and use the second pattern jig that has already been cleaned, and when the second pattern jig is rotated downward by 90 degrees, the second brush moves left and right to clean the second pattern jig and use the first pattern jig that has already been cleaned.

[0011] Another object of the present invention is to provide an automatic cleaning device for pattern jigs after laser notching, which automatically cleans the pattern jigs by moving the brush left and right at a fixed time period, alternately removes contaminants generated on the supporting portions of the first and second pattern jigs, and discharges the removed contaminants to the outside by vacuum suction, thereby cleaning the pattern jigs cleanly. [Means for solving the problem]

[0012] To achieve this object, the present invention is characterized in that, in a process of supporting a pattern jig and cutting an uncoated plain portion with a laser, the process includes first and second pattern jigs installed on an upper surface and one side of a square rotating body, a motor for rotating the rotating body within a 90 degree range, a first upper brush fixing plate and a first lower brush fixing plate having a first brush for cleaning the first pattern jig when the first pattern jig is positioned upward, a first brush unit for moving the upper and lower brush fixing plates left and right, a second upper brush fixing plate and a second lower brush fixing plate having a second brush for cleaning the second pattern jig when the second pattern jig is positioned downward, a second brush unit for moving the second upper and lower brush fixing plates left and right, and a pattern jig unit for moving the first and second pattern jigs left and right. Effect of the Invention

[0013] In the present invention as described above, when positively coating an aluminum foil and negatively coating a copper foil, and cutting an uncoated plain portion with a laser, the pattern jig periodically rotates up and down within 90 degrees in order to remove particles attached to the supporting portion of the pattern jig due to high temperature. When the pattern jig is in the upper position or the pattern jig is in the lower position, the brushes move left and right to remove fumes and particles attached to the pattern jig. In addition, a clean pattern jig from which particles have already been removed can be used to perform continuous cutting of the plain portion. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0016] FIG. 1 is an oblique view showing the overall pattern jig unit portion including the brush of the present invention, FIG. 2 is an oblique view of the brush and pattern jig unit viewed in the direction of the arrow in FIG. 1, FIG. 3 is an oblique view showing the operation of the first brush cleaning the first pattern jig when the first pattern jig is positioned upward by rotating 90 degrees upward according to the present invention, and FIG. 4 is an oblique view showing the operation of the second brush cleaning the second pattern jig when the second pattern jig is positioned downward by rotating 90 degrees according to the present invention. As shown in these figures, the cleaning device comprises first and second pattern jigs 2, 3 respectively installed on the upper surface and one side surface of a square rotating body 1, a motor 4 for rotating the rotating body 1 within a 90 degree range, a first upper brush fixing plate 5 and a first lower brush fixing plate 6 having a first brush 7 for cleaning the first pattern jig 2 when the first pattern jig 2 is positioned upward, a first brush unit 11 for moving the upper and lower brush fixing plates 5, 6 left and right, a second upper brush fixing plate 8 and a second lower brush fixing plate 9 having a second brush 10 for cleaning the second pattern jig 3 when the second pattern jig 3 is positioned downward, a second brush unit 12 for moving the upper and lower brush fixing plates 8, 9 left and right, and a pattern jig unit 13 for moving the first and second pattern jigs 2, 3 left and right.

[0017] Here, the first and second pattern jigs 2, 3 have the same structure and are fixed to the corner portion 1a of the rotating body 1 so as not to protrude therefrom.

[0018] Here, the motor 4 may be a rotating cylinder.

[0019] The operation of the present invention thus configured will now be described.

[0020] In the process of cleaning particles from the laser pattern jig of the present invention, first, as shown in FIG. 3, when the second pattern jig 3 is in use, the first pattern jig 2 is positioned 90 degrees upward.

[0021] Therefore, with the first pattern jig 2 positioned above, the first brush unit 11 moves the entire unit left and right, so that the first brush 7 removes particles from the first pattern jig 2. At this time, interference is prevented by the movement of the entire unit.

[0022] The first brush 7 is provided on the upper and lower surfaces of the first upper brush fixing plate 5 and the first lower brush fixing plate 6, respectively, so that the first brush 7 passes through the first pattern jig 2 as the unit moves left and right, thereby removing particles cleanly.

[0023] Here, the first brush unit 11 has a lower motor driving part connected to an "L"-shaped guide 11b and a vertical guide 11a, and the vertical guide 11a is integrally connected to the first upper and lower brush fixing plates 5 and 6 to form a single unit.

[0024] Similarly to the configuration of the first brush unit 11, the second brush unit 12 is integrally joined by a guide or the like to form a single unit.

[0025] As described above, when a certain time has passed since the first pattern jig 2 was cleaned, particles attached to the second pattern jig 3 that has already been used are removed, and the first pattern jig 2 that has been cleaned is replaced and used.

[0026] That is, at this time, as shown in FIG. 4, the rotating body 1 rotates downward by 90 degrees by the drive of the motor 4, so that the first pattern jig 2 which has been cleaned is positioned at the infrared use position, and the second pattern jig 3 which has already been used is rotated by 90 degrees and positioned downward.

[0027] Therefore, with the second pattern jig 3 rotated 90 degrees and positioned below, the second brush unit 12 moves the entire unit left and right, so that the second brush 10 removes particles from the second pattern jig 3. Even in this case, interference is prevented by the movement of the entire unit.

[0028] The second brush 10 is provided on the upper and lower surfaces of the second upper brush fixing plate 8 and the second lower brush fixing plate 9, respectively, so that the second brush 10 passes through the second pattern jig 3 as the unit moves left and right, thereby removing particles cleanly.

[0029] On the other hand, the pattern jig unit 13 of the present invention is configured so that the entire unit can move, as shown in Fig. 2, and therefore interference can be prevented. Fig. 2 is a perspective view of the shape as seen in the direction of the arrow in Fig. 1.

[0030] That is, according to the present invention, after the pattern jig unit 13 is moved left and right, the first and second pattern jigs 2, 3 rotate due to the rotation of the rotating body 1 driven by the motor 4, thereby automatically performing cleaning, and then, while the pattern jig unit 13 is moving left and right, the positions of the first and second pattern jigs 2, 3 are confirmed and cleaning is performed.

[0031] The present invention as described above has been described as an example of the technical concept, and a person having ordinary knowledge in the technical field to which the present invention pertains may make various modifications, changes and substitutions without departing from the essential characteristics of the present invention.

[0032] Therefore, the embodiments and accompanying drawings disclosed in the present invention are for illustrative purposes and not for limiting the technical idea of ​​the present invention, and the scope of the technical idea of ​​the present invention is not limited by such embodiments and accompanying drawings.
