Description

Technology Field

[0001] The present invention relates to a patternless jig device applied to a laser notching device, and more specifically, to a patternless jig device for a laser notching device that allows the arrangement of the jig roller and the notching line support to be selectively changed so as to be commonly applied to multiple production lines, and allows the length of the jig body and the spacing of the jig roller to be adjusted based on fastening holes. Background Technology

[0002] In general notching processes, pattern jigs are used for each production line. Pattern jigs are structured to directly support the bottom of the notching area of ​​the electrode sheet; however, this structure hinders the scattering of foreign substances generated during the notching process to the outside. Furthermore, because the pattern jigs block the airflow of the dust suction device, there is a problem in that dust generated during the notching process cannot be efficiently removed.

[0003] Such dust accumulation causes disturbances in the laser beam path, making it impossible to precisely obtain the desired electrode tab shape; consequently, this acts as a significant cause of increased product defect rates and degraded product quality. Therefore, in conventional pattern jig-based notching processes, issues such as difficulty in dust removal, deterioration of the process environment, and increased product defect rates have been continuously raised.

[0004] To solve these problems, the applicant has developed the technology disclosed in Registered Patent Publication No. 10-2771652 (hereinafter referred to as the "prior art"), which describes a laser notching device applying a roller-type jig instead of a conventional pattern jig. In the prior art, the jig roller supports the lower part of the electrode sheet through line contact, thereby preventing dust discharge and improving the process environment to enhance product quality.

[0005] However, since the aforementioned conventional technology is also structured to be set up for a specific production line, there is a demand for a jig device capable of covering multiple production lines. Prior art literature

[0006] Registered Patent Publication No. 10-2771652 (Registered on Feb. 18, 2025) The problem to be solved

[0007] The present invention was developed to improve upon the aforementioned problems, and the objective of the present invention is to provide a patternless jig device for a laser notching device that allows the arrangement of the jig roller and the notching line support to be selectively changed so as to be applicable to multiple production lines, and allows the length of the jig body and the spacing of the jig roller to be adjusted based on fastening holes. means of solving the problem

[0008] The present invention relates to a patternless jig device for a laser notching device applicable to a plurality of production lines, comprising: a jig body (100); a pair of jig rollers (200) spaced apart and facing each other along the width direction of the jig body (100); and a notching line support member (300) provided on the jig body (100) to guide and support the driving of a pair of jig rollers (200) at the bottom, wherein a plurality of notching spaces (20) are partitioned along the length direction of the jig body (100), and each of the plurality of notching spaces (20) is formed to correspond to a different production line.

[0009] Meanwhile, the jig body (100) has a first body length adjustment hole (111) and a second body length adjustment hole (121) formed in the first body (110) and the second body (120), respectively, and the length of the jig body (100) is adjusted by selectively connecting the first body (110) and the second body (120).

[0010] Meanwhile, a plurality of notching gap adjustment holes (140) are formed at both ends in the longitudinal direction of the jig body (100), and the spacing between a pair of jig rollers (200) is adjusted by selectively connecting both ends of the jig roller (200) to the notching gap adjustment holes (140).

[0011] At both ends of the width direction of the above jig body (100), tension rollers (160) are each provided, configured to move the electrode sheet being inserted and withdrawn with a constant tension, and connected so as to allow adjustment of the position in the vertical direction.

[0012] The above notching line support member (300) is characterized by being fastened to a selected position among a plurality of placement position adjustment holes (170) formed along the longitudinal direction of the jig body (100).

[0013] The above notching line support (300) is configured to allow adjustment of the vertical position of the roller (320) provided at the end.

[0014] At this time, the notching line support member (300) is characterized by comprising: a first bracket (310) having an elongated hole (311) formed in the vertical direction on the surface; a plurality of rollers (320) provided at the upper end of the first bracket (310); and a second bracket (330) having a through hole formed on the surface corresponding to the elongated hole (311) and fixed to the upper part of the jig body (100).

[0015] On the opposite side of the above notching line support member (300), a sagging prevention member (400) that guides and supports the driving of the jig roller (200) may be further provided.

[0016] It is characterized by further including a residual laser processing unit (500) that absorbs or disperses residual laser that has passed through the above notching space (20). Effects of the invention

[0017] According to the present invention, a pair of jig rollers are extended and configured to selectively change the longitudinal position of the notching line support, thereby having the advantage of being applicable to multiple production lines.

[0018] To elaborate, in the present invention, by dividing multiple notching spaces based on the placement position of the notching line support, a single jig roller configuration can be applied to multiple production lines. Therefore, even when switching production lines, there is no need to replace the device, and the notching process can be performed simply by guiding the electrode sheet to the corresponding notching space, thereby improving line switching speed and significantly enhancing production efficiency.

[0019] In addition, since the length of the jig body and the spacing of the jig rollers in the present invention are configured to be adjustable based on fastening holes, the jig device can be quickly set up to match the specifications of the electrode sheet to be produced. This allows for support of various electrode sheet specifications without the need for device replacement.

[0020] In addition, by providing a sagging prevention member, the sagging of the elongated jig roller can be effectively suppressed. As a result, stable support of the jig roller becomes possible, and the durability and reliability of the device are enhanced. Brief explanation of the drawing

[0022] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings so that a person skilled in the art to which the present invention pertains can easily practice the present invention.

[0023] The present invention relates to a patternless jig device applied to a laser notching device (1), and more specifically, to a patternless jig device for a laser notching device in which the arrangement of the jig roller (200) and the notching line support (300) can be selectively changed so as to be applied commonly to multiple production lines, and the length of the jig body (100) and the spacing of the jig roller (200) can be adjusted based on fastening holes.

[0024] As illustrated in FIG. 1, the present invention is described based on a jig body (100). The longitudinal direction of the jig body (100) is defined as the X-axis, the width direction as the Y-axis, and the vertical direction as the Z-axis. At this time, the transport direction of the electrode sheet coincides with the width direction (Y-axis) of the jig body (100), and the width direction of the electrode sheet corresponds to the longitudinal direction (X-axis) of the jig body (100). This is intended to aid in understanding the invention, and the present invention is not limited thereto.

[0025] Meanwhile, the jig device of the present invention is applied to a laser notching device (1), and the laser notching device (1) is a device that forms a certain pattern by notching one side of an electrode sheet during the process in which the electrode sheet is transported with a certain tension by a plurality of guide rollers (40), etc. by using an optical device that irradiates a light source (30) such as a laser beam. The jig device (10) of the present invention is placed below the electrode sheet to guide and support the transport of the electrode sheet during this notching process.

[0026] The notching space (20) refers to a space where a laser beam is irradiated to perform notching of the electrode sheet. The specifications of the notching space (20), including the spacing (distance in the X-axis direction), the position in the longitudinal direction, and the spacing (position in the Y-axis direction), must vary depending on the specifications of the secondary battery to be produced or the specifications of the pattern to be manufactured, i.e., the production line. Previously, there were many time and cost constraints because the entire jig device had to be replaced to set the specifications of the notching space (20) suitable for a specific production line. However, the patternless jig device (10) of the present invention is configured to correspond to multiple production lines, so these problems can be effectively solved.

[0027] To this end, the patternless jig device (10) according to the present invention comprises a jig body (100), a pair of jig rollers (200), and a notching line support (300).

[0028] According to FIGS. 2 to 5, the jig body (100) serves as a basic frame that supports the lower part of the electrode sheet, on which each component of the patternless jig device (10) is installed. The jig body (100) is formed to have a predetermined length and width and is fixedly installed on the wall of the notching device, etc. The jig body (100) is configured so that its overall length is adjustable and it can be raised and lowered in the vertical direction, so that a single jig body (100) can accommodate various production specifications.

[0029] As described above, as illustrated in FIG. 4, the jig body (100) includes a first body (110) in which a first body length adjustment hole (111) is arranged in the longitudinal direction and a second body (120) in which a second body length adjustment hole (121) is arranged in the longitudinal direction, and the total length of the jig body (100) can be adjusted by connecting the first body length adjustment hole (111) and the second body length adjustment hole (121) selected when the first body (110) and the second body (120) are overlapped.

[0030] As illustrated in FIGS. 3 and 5, a jig roller (200), a notching line support (300), etc. are installed on one of the first body (110) and the second body (120), and this is installed on the wall of the notching device while being fixedly seated on the upper part of the other body. In the present invention, for the sake of understanding the invention, various parts are installed on the first body (110) and the second body (120) is installed on the notching device, but this is not limited thereto.

[0031] Meanwhile, one end of the jig body (100) in the longitudinal direction is equipped with a lifting means (130) and installed in a notching device so as to be able to be raised and lowered in the vertical direction. To elaborate, the lifting means (130) may include a linear guide and a ball screw, or a pneumatic or hydraulic cylinder, and may be configured so that the jig body (100) can be stably raised and lowered in the Z-axis direction.

[0032] According to the above configuration, the jig body (100) can cover production lines of various specifications.

[0033] As shown in FIGS. 2 and 3, a pair of jig rollers (200) serve as the patternless jig of the notching device and are spaced apart from each other along the width direction of the jig body (100) to guide and support the lower surface of the electrode sheet (not shown).

[0034] The jig roller (200) is formed long along the longitudinal direction of the jig body (100) and configured to cover all widths required by multiple production lines. That is, since the jig roller (200) supports the electrode sheet equally regardless of which notching space (20) it is transported along, it can be used in various production lines without separate replacement.

[0035] As illustrated in FIGS. 4 and 7, the spacing between a pair of jig rollers (200) can be changed by a notching spacing adjustment hole (140) provided in the jig body (100). Specifically, a plurality of notching spacing adjustment holes (140) are provided at each end of the length direction of the jig body (100) so as to be spaced apart in the width direction, and the spacing between the jig rollers (200) can be adjusted by inserting and fastening a pair of jig rollers (200) into one of the selected adjustment holes. Accordingly, the notching spacing can be adjusted to match the specifications of the electrode sheet or the specifications required by the production line.

[0036] As shown in FIGS. 2 and 6, the notching line support (300) is provided in the jig body (100) to guide and support the driving of the pair of jig rollers (200) from below, and is intended to support a pair of jig rollers (200) and to partition a plurality of notching spaces (20).

[0037] As illustrated in FIG. 8, the notching line support member (300) is configured to have a changeable position so as to correspond to a change in the height of the jig roller (200). For example, the notching line support member (300) includes a first bracket (310) having an elongated hole (slit, 311) extending vertically on a surface, a plurality of rollers (320) provided at the upper end of the first bracket (310), and a second bracket (330) fixed to the upper part of the jig body (100) having a through hole formed on the surface corresponding to the elongated hole (311).

[0038] At this time, multiple rollers (320) are arranged to cover the entire width of the jig body (100), and can be selectively installed or removed as needed. The notching line support (300) is fixed by a fastening bolt penetrating both the elongated hole (311) and the through hole while the fastening height between the first bracket (310) and the second bracket (330) is adjusted, so the position can be adjusted in the vertical direction along the elongated hole (311). Therefore, even if the installation height of the jig roller (200) varies depending on the specifications of the electrode sheet or production line conditions, an optimal support position can be secured.

[0039] Additionally, the second bracket (330) is further provided with a mounting groove (331) that guides the first bracket (310) to be fastened and seated. It is preferable that the mounting groove (331) be formed in the shape of a groove that extends upward from one side of the second bracket (330) and has an open upper side. Accordingly, the first bracket (310) can be stably seated on the second bracket (330) while being guided by the mounting groove (331), and the phenomenon of the position shifting out of alignment during the fastening process can be prevented.

[0040] Additionally, a plurality of notching spaces (20) are partitioned in the longitudinal direction based on the location where the notching line support (300) is provided, and these notching spaces (20) correspond to each production line. Therefore, when a specific production line is selected, the electrode sheet is guided through the corresponding notching space (20) and the notching operation is performed.

[0041] The notching line support (300) can be adjusted in position through a placement position adjustment hole (170) provided in the jig body (100). That is, a plurality of placement position adjustment holes (170) are spaced apart along the longitudinal direction of the jig body (100), and a corresponding adjustment hole is provided in the notching line support (300) to be coupled with a selected placement position adjustment hole (170). In this way, various production conditions can be accommodated using the same jig device even when the production line is changed or the specifications of the notching space (20) change.

[0042] In the present invention, an example is illustrated in which a single notching line support (300) is provided to divide the notching space (20) into two (20a, 20b), but this is merely for convenience of explanation and the present invention is not limited thereto. That is, if a plurality of notching line support (300) are provided according to the specifications of the production equipment, a single jig device can be divided into more notching spaces to cover all various production lines.

[0043] In the present invention, since one longitudinal side of the jig body (100) is installed and used in a notching device, the notching space (20) is offset toward the protruding end side, which is opposite to the installation end (fixed end) of the jig body (100). Along with this, the notching line support (300) is also provided toward the protruding end side.

[0044] At this time, in the present invention, since the thin jig roller (200) is formed in a shape that is sufficiently extended in the longitudinal direction, sagging may occur. To prevent this, a sagging prevention part (400) that supports the lower side and is provided on the jig body (100) in the longitudinal direction opposite to the jig roller (200) may be further provided.

[0045] The sagging prevention member (400) is provided across the spare space on the opposite side in the longitudinal direction, excluding the notching space (20), and effectively prevents sagging by supporting the lower end of the jig roller (200) that crosses the section. Specifically, the sagging prevention member (400) is configured in a form in which multiple roller modules, each having multiple rollers attached to a single rotation axis, are arranged in the width direction, and can respond to changes in production line specifications by removing or adding rollers of each roller module.

[0046] The sagging prevention member (400) configured as described above supports the electrode sheet in cooperation with the notching line support member (300), thereby ensuring uniform stability throughout the entire longitudinal section of the long jig roller (200).

[0047] The rollers of the jig roller (200) and the notching line support (300) can be made of, for example, a metal material, a synthetic resin material, or a material having a friction-reducing coating formed on its surface, and can be deformed into a cylindrical, tapered, or multiple stepped shape.

[0048] The jig roller (200), notching line support (300), and sagging prevention part (400) can be selectively fixed by a bolt / nut, a fastening pin, or a sliding fixing member through the fastening hole and the adjustment hole, and accordingly, the operator can adjust the position of the part with only a simple fastening operation.

[0049] Each component constituting the jig device (100) has a modular structure, so replacement and maintenance of individual modules are easy when switching production lines, and maintenance is improved as a worker can simply separate and reassemble them on-site.

[0050] As shown in FIG. 7, a residual laser processing unit (500) may be further provided at the lower part of the jig body (100). To elaborate, a passage (150) through which a laser, which is a light source (30), passes is formed in the jig body (100) corresponding to the notching space (20), and the residual laser processing unit (500) is provided in a box-shaped structure with an open top to seal the bottom of the passage (150). A structure that disperses and absorbs the laser is provided inside to safely process the laser remaining after notching.

[0051] Tension rollers (160) that guide the insertion and withdrawal of electrode sheets are provided at each of the widthwise ends of the jig body (100). The tension rollers (160) are formed to extend in the longitudinal direction and are installed at both widthwise ends of the jig body (100) so as to be rotatable. Through this, the electrode sheet is supplied to the notching space (20) with constant tension, the notching process is performed stably, and the electrode sheet can be discharged smoothly after notching.

[0052] The jig device of the present invention configured as described above is formed such that each of the plurality of notching spaces (20) corresponds to a different production line. Accordingly, a single jig roller (200) configuration can cover multiple production lines in common.

[0053] For example, when producing both prismatic and cylindrical batteries, the protrusion length of the jig body (100), the width spacing of the jig roller (200), and the position of the notching line support (300) are adjusted to form a notching space (20a) for the prismatic production line and a notching space (20b) for the cylindrical production line, respectively, as shown in FIG. 5. As a result, when an electrode sheet is supplied to the selected production line, a notching process is performed in the corresponding notching space (20). Subsequently, when the production line is changed, the electrode sheet is supplied to a different notching space (20) to perform a notching process of a different specification without replacing a separate device.

[0054] In addition, if the specifications of the electrode sheet itself change, the new production conditions can be accommodated by readjusting the protrusion length of the jig body (100), the width spacing of the jig roller (200), the position of the notching line support (300), etc.

[0055] Meanwhile, the present specification and drawings disclose preferred embodiments of the present invention. Although specific terms have been used, they are used merely in a general sense to facilitate the explanation of the technical content of the present invention and to aid in understanding the invention, and are not intended to limit the scope of the present invention.
