Description
本発明は、板状の電池と、該電池の少なくとも側面を囲む外装体とを備え、外装体及び電池、又は、外装体にラベルを巻着した電池パックに関する。 The present invention relates to a battery pack that includes a plate-shaped battery and an exterior body that surrounds at least a side surface of the battery, and has a label wound around the exterior body and the battery.
近年、携帯機器などの電子機器の小型化に伴い、前記電子機器に内蔵する電池パックの小型化に対する要求が高まっており、例えば電池を枠状の外装体に収納し、ラベルを巻着した電池パックが用いられている（例えば、特許文献１参照）。ただし、ラベルを巻着した場合は、ラベルが外装体又は電池に対して凸状となって段差が生じるため、電池パックを手に持った際に前記段差に指又は爪が引っ掛かるなどして違和感が生じたり、ラベルが剥がれる原因となる。 In recent years, along with the downsizing of electronic devices such as portable devices, there has been an increasing demand for downsizing of battery packs built in the electronic devices. A pack is used (see, for example, Patent Document 1). However, when the label is wound, the label becomes convex with respect to the outer package or the battery, and a step is generated. Therefore, when the battery pack is held in the hand, a finger or a nail is caught on the step, and thus the user feels uncomfortable. Or the label may be peeled off.
そのため、外装体にラベルの厚さに合わせた凹部を形成し、前記凹部にラベルを巻着している。この場合、ラベルは前記凹部に埋め込まれた状態になるため前記段差は生じず、上述した前記段差によって違和感が生じたり、ラベルが剥がされることを防止できる。ただし、前記凹部とラベル外縁との間隔が大きい場合は、ラベルが凹部の底面に対して凸状となり前記段差が生じるため、前記凹部とラベル外縁との間隔は可能な限り小さくすることが好ましい。 Therefore, a concave portion corresponding to the thickness of the label is formed in the exterior body, and the label is wound around the concave portion. In this case, since the label is embedded in the recess, the step does not occur, and it is possible to prevent the above-described step from causing a sense of incongruity or peeling off the label. However, when the interval between the recess and the label outer edge is large, the label is convex with respect to the bottom surface of the recess and the step is generated. Therefore, the interval between the recess and the label outer edge is preferably as small as possible.
図１は、電池パックの分解斜視図であり、図７は従来のラベルの例を示す平面図であり、図８（ａ）及び（ｂ）は従来のラベルを巻着した電池パックの例を示す表面図及び側面図である。図１の例では、角型平板状の電池１０及び保護回路基板１２が、四角形状の外装枠（外装枠上半体１４、外装枠下半体１６）に収容され、電池１０及び外装枠１４，１６にラベル８を巻着している。ラベル８は、図７に示すように、四角形状であり、外装枠１４、１６短辺の位置合せ凹部１４ａ，１６ａに貼着する位置合せ凸部８ａを有する。外装枠１４，１６には短辺に平行な凹部が形成されており、図８（ｂ）に示すように、凹部とラベル８外縁とが平行になるように、ラベル８を電池１０及び外装枠１４，１６に巻着する。
ラベルを巻着する際は、気泡が生じないように、ラベルを引っ張りながら巻着していく。その際、一般的なラベルは薄いプラスチックフィルム製であることが多く、柔軟性が高い反面、巻着時にラベルが伸長する場合が多い。また、柔軟性が高く、伸長し易いため、巻着時にラベルが蛇行することも多い。そのため、前記凹面とラベル外縁との間隔が小さい場合、図８（ａ）に示すように、ラベルの伸長又は蛇行により、ラベルが凹部を超えて外装体に乗り上げることがある。このようにラベルが凹部を超えて外装体に乗り上げた電池は外観不良となる。 When the label is wound, the label is wound while pulling the label so as not to generate bubbles. At that time, a general label is often made of a thin plastic film and has high flexibility, but the label is often elongated when wound. Moreover, since it is highly flexible and easily stretched, the label often meanders during winding. Therefore, when the interval between the concave surface and the outer edge of the label is small, the label may run over the concave portion over the concave portion due to the extension or meandering of the label, as shown in FIG. Thus, the battery in which the label rides on the exterior body beyond the concave portion is defective in appearance.
本発明は斯かる事情に鑑みてなされたものであり、ラベルの巻着終端側の幅を先細にしたことにより、外観不良の発生を減少することができる電池パックを提供することを目的とする。 This invention is made in view of such a situation, and it aims at providing the battery pack which can reduce generation | occurrence | production of an appearance defect by tapering the width | variety of the winding end side of a label. .
また、本発明は、ラベルの幅を、電池の表面側及び裏面側では一定とし、側面側で変化させることにより、デザイン性を損なわず、外観不良の発生を減少することができる電池パックを提供することを他の目的とする。 In addition, the present invention provides a battery pack in which the width of the label is constant on the front surface side and the back surface side of the battery and is changed on the side surface, thereby reducing the occurrence of appearance defects without impairing the design. To do other purposes.
また、本発明は、ラベルの先細の先端部の幅と、先細になっていない部分の幅との差を、先細になっている部分の巻着方向の長さの０．１％以上、１．０％以下にしたことにより、デザイン性を損なわず、外観不良の発生を減少することができる電池パックを提供することを他の目的とする。 Further, according to the present invention, the difference between the width of the tapered leading end portion of the label and the width of the non-tapered portion is not less than 0.1% of the length in the winding direction of the tapered portion. Another object of the present invention is to provide a battery pack capable of reducing the occurrence of poor appearance without impairing the design by setting the ratio to 0.0% or less.
第１発明に係る電池パックは、板状の電池と、該電池の少なくとも側面を囲む外装体とを備え、外装体及び電池、又は、外装体にラベルを巻着した電池パックにおいて、前記ラベルの巻着終端側の幅が先細になっていることを特徴とする。 A battery pack according to a first aspect of the present invention is a battery pack comprising a plate-shaped battery and an exterior body surrounding at least a side surface of the battery, and the battery pack in which the label is wound around the exterior body and the battery or the exterior body. The winding end side is tapered in width.
第２発明に係る電池パックは、第１発明において、前記ラベルの幅は、前記電池の表面側及び裏面側では一定であり、側面側で変化していることを特徴とする。 The battery pack according to a second invention is characterized in that, in the first invention, the width of the label is constant on the front surface side and the back surface side of the battery and changes on the side surface side.
第３発明に係る電池パックは、第１又は第２発明において、前記ラベルの先細の先端部の幅と、先細になっていない部分の幅との差は、先細になっている部分の巻着方向の長さの０．１％以上、１．０％以下であることを特徴とする。 The battery pack according to a third aspect of the present invention is the battery pack according to the first or second aspect, wherein the difference between the width of the tapered leading end portion of the label and the width of the non-tapered portion is winding of the tapered portion. It is characterized by being 0.1% or more and 1.0% or less of the length in the direction.
第１発明においては、前記ラベルの巻着終端側の幅を先細にしているため、巻着時にラベルが延伸又は蛇行した場合であっても、巻着を行う規定範囲からラベルがはみ出すことを防止できる。これにより、外観不良の発生を減少することができる。 In the first invention, since the width of the winding end side of the label is tapered, even when the label is stretched or meandering at the time of winding, the label is prevented from protruding from the specified range for winding. it can. Thereby, the occurrence of appearance defects can be reduced.
第２発明においては、目に付き易い電池の表面側及び裏面側でラベルの幅は変化させず、目に付き難い電池の側面側でラベルの幅を変化させているため、巻着終端側の幅を先細にしたことによるラベル幅の変化はユーザの目に付き難い。そのため、デザイン性を損なわず、外観不良の発生を減少することができる。 In the second invention, the width of the label is not changed on the front side and the back side of the battery that is easily noticeable, and the width of the label is changed on the side surface of the battery that is not easily noticeable. The change in the label width due to the taper being narrow is difficult for the user to notice. Therefore, the appearance can be reduced without impairing the design.
第３発明においては、ラベルの先細の先端部の幅と、先細になっていない部分の幅との差は、先細になっている部分の巻着方向の長さの０．１％以上、１．０％以下であるため、先細部分の幅の低下量は少なく、先細になっていることは目立ち難い。そのため、デザイン性を損なわず、外観不良の発生を減少することができる。 In the third invention, the difference between the width of the tapered leading end of the label and the width of the non-tapered portion is not less than 0.1% of the length in the winding direction of the tapered portion. Since it is 0.0% or less, the amount of decrease in the width of the tapered portion is small, and it is difficult to notice that the taper is tapered. Therefore, the appearance can be reduced without impairing the design.
第１発明によれば、巻着時にラベルが延伸又は蛇行した場合であっても、巻回の規定範囲からラベルがはみ出すことを防止し、外観不良の発生を減少することができる。 According to the first invention, even when the label is stretched or meandering at the time of winding, it is possible to prevent the label from protruding from the specified range of winding, and to reduce the occurrence of poor appearance.

以下、本発明をその実施の形態を示す図面に基づいて具体的に説明する。図１は、電池パックの分解斜視図であり、図２及び図４（ａ）は本発明に係るラベルの例を示す平面図であり、図３（ａ）及び（ｂ）は本発明に係るラベルを巻着した電池パックの例を示す表面図及び側面図である。 Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof. FIG. 1 is an exploded perspective view of a battery pack, FIG. 2 and FIG. 4 (a) are plan views showing examples of labels according to the present invention, and FIGS. 3 (a) and 3 (b) are related to the present invention. It is the surface view and side view which show the example of the battery pack which wound the label.
電池１０は、角型の平板形状をしており、短側面の一方に、長方形状の保護回路基板１２が配置されている。電池１０及び保護回路基板１２は、四角形状の外装枠（外装体）に収容される。外装枠は、上下に分割された外装枠上半体１４及び外装枠下半体１６を溶着したものであり、保護回路基板１２及び電池１０の側面を囲むように収容する。外装枠上半体１４及び外装枠下半体１６には短辺に平行な凹部が形成されており、前記凹部、電池１０の表面及び裏面にラベル１８が巻着される。前記凹部の深さはラベル１８の厚みと同程度又は僅かに大きく、前記凹部の底面は、電池１０の表面又は裏面とほぼ同一平面上に位置している。また、外装枠１４，１６の他方の短側面には、ラベル１８の位置合せ用の位置合せ凹部１４ａ，１６ａが形成されている。電池１０のサイズは、長さ５０ｍｍ、幅３４ｍｍ、厚さ５．２ｍｍであり、電池パックのサイズは長さ５８ｍｍ、幅３６ｍｍ、厚さ５．８ｍｍである。 The battery 10 has a rectangular flat plate shape, and a rectangular protection circuit board 12 is disposed on one of the short side surfaces. The battery 10 and the protection circuit board 12 are accommodated in a rectangular outer frame (exterior body). The outer frame is formed by welding the upper half 14 and the lower half 16 of the outer frame, which are divided into upper and lower parts, and accommodates the protective circuit board 12 and the battery 10 so as to surround the side surfaces. The outer frame upper half 14 and the outer frame lower half 16 are formed with recesses parallel to the short sides, and a label 18 is wound around the recesses and the front and back surfaces of the battery 10. The depth of the concave portion is approximately the same as or slightly larger than the thickness of the label 18, and the bottom surface of the concave portion is positioned substantially on the same plane as the front or back surface of the battery 10. In addition, alignment concave portions 14 a and 16 a for alignment of the label 18 are formed on the other short side surfaces of the exterior frames 14 and 16. The battery 10 has a length of 50 mm, a width of 34 mm, and a thickness of 5.2 mm, and the battery pack has a length of 58 mm, a width of 36 mm, and a thickness of 5.8 mm.
ラベル１８は、ほぼ四角形状をしており、長辺の一部には、前記位置合せ凹部１４ａ，１６ａに貼着する位置合せ凸部１８ａを有する。ラベル１８の幅については、図２に示すように、一方の短辺側が先細になっており、先細になっていない平行な長辺部分の一方に位置合せ凸部１８ａが形成されている。ラベル１８の先細になっていない方の短辺（以下、通常短辺という）側の幅Ａと、先細になっている方の短辺（以下、先細短辺という）側の幅Ｂとの差（＝Ａ−Ｂ）は、先細になっている部分の巻着方向の長さＣの０．１％以上、１．０％以下である。また、通常短辺側の幅Ａと先細短辺側の幅Ｂとの差は、図４（ａ）に示すように、位置合せ凸部１８ａが形成されている側の差ｄ１と他方側の差ｄ２との合計（ｄ１＋ｄ２）になるが、本実施の形態ではｄ１＝ｄ２＝０．０８ｍｍである。また、本実施の形態ではラベルの通常短辺側の幅Ａ＝５１ｍｍ、先細になっている部分の巻着方向の長さＣ＝４０ｍｍ、全長は８７ｍｍである。なお、図においては、先細部分を誇張して図示しているが、実際の先細部は図よりも平行に近い。また、ラベル１８は、例えばＰＥＴ（Polyethylene Terephthalate）の基材に、ＰＥＴ又はＰＰ（Polypropylene）のラミネートを行っており、アクリル系の接着剤で貼着する。 The label 18 has a substantially quadrangular shape, and has an alignment convex portion 18a attached to the alignment concave portions 14a and 16a at a part of the long side. As for the width of the label 18, as shown in FIG. 2, one short side is tapered, and an alignment convex portion 18 a is formed on one of the parallel long sides that are not tapered. The difference between the width A of the shorter side (hereinafter, referred to as a normal short side) of the label 18 and the width B of the shorter side (hereinafter, referred to as a tapered short side) of the tapered side. (= AB) is 0.1% or more and 1.0% or less of the length C in the winding direction of the tapered portion. In addition, the difference between the width A on the short side and the width B on the tapered short side is, as shown in FIG. 4 (a), the difference d1 on the side on which the alignment convex portion 18a is formed and the other side. Although it is the sum (d1 + d2) with the difference d2, in this embodiment, d1 = d2 = 0.08 mm. In the present embodiment, the width A of the normal short side of the label is 51 mm, the length C of the tapered portion in the winding direction is C = 40 mm, and the total length is 87 mm. In the figure, the tapered portion is exaggerated, but the actual taper is closer to parallel than in the figure. For example, the label 18 is obtained by laminating PET or PP (Polypropylene) on a PET (Polyethylene Terephthalate) base material, and sticking it with an acrylic adhesive.
ラベル１８を外装枠１４，１６及び電池１０に巻着する際は、外装枠下半体１６の位置合せ凹部１６ａにラベル１８の位置合せ凸部１８ａが位置し、外装枠１６の凹部とラベル１８の先細でない長辺部分とが平行となるように貼着する。次に、ラベル１８の位置合せ凸部１８ａを反対面側に折り返して貼着し、また、ラベル１８の通常短辺側を、気泡が生じないように引き伸ばしながら巻着する。なお、位置合せ凸部１８ａ及び通常短辺側は、延伸したり蛇行が生じるほどの長さはなく、斜めに貼着するなどの問題が生じることは少ない。 When the label 18 is wound around the outer frames 14 and 16 and the battery 10, the alignment convex portion 18 a of the label 18 is positioned in the alignment concave portion 16 a of the lower half 16 of the outer frame, and the concave portion of the outer frame 16 and the label 18. Adhere so that the non-tapered long side part is parallel. Next, the alignment convex portion 18a of the label 18 is folded and attached to the opposite surface side, and the normal short side of the label 18 is wound while being stretched so as not to generate bubbles. In addition, the alignment convex part 18a and the normal short side are not long enough to stretch or cause meandering, and problems such as sticking obliquely rarely occur.
その後、ラベル１８の先細部分を、気泡が生じないように引き伸ばしながら巻着する。なお、先細部分は、延伸したり蛇行が生じる程度の長さを有し、斜めに貼着するなどの問題が生じる。しかし、前記先細部分は、図２に示したように先細になっているため、延伸したり蛇行が生じて、斜めに巻着された場合であっても、ラベル１８外縁が外装体１４の凹部を超えて乗り上げることを防止できる。なお、ラベル１８の巻着は、手で行ったり、機械で行うことが可能である。 Thereafter, the tapered portion of the label 18 is wound while being stretched so as not to generate bubbles. The tapered portion has such a length as to cause stretching or meandering, and causes problems such as sticking obliquely. However, since the tapered portion is tapered as shown in FIG. 2, the outer edge of the label 18 is a concave portion of the outer package 14 even when it is stretched or meandered and wound obliquely. Can be prevented from climbing over. The label 18 can be wound by hand or by a machine.
上述した実施の形態においては、通常短辺側の幅Ａと先細短辺側の幅Ｂとの差（＝ｄ１＋ｄ２）を、図４（ａ）に示すように、ｄ１＝ｄ２にしているが、ｄ１及びｄ２は任意に調整することが可能である。図４（ｂ）及び（ｃ）は、本発明に係るラベルの他の例を示す平面図である。図４（ｂ）においてはｄ１＞ｄ２である。また、図４（ｃ）においてはｄ２＝０である。ｄ１及びｄ２の値は、例えばラベルを巻着した電池パックの品質管理に基づいて、調整することが可能である。また、先細短辺側の幅Ｂも任意に調整することが可能であり、例えばラベルを巻着した電池パックの品質管理に基づいて、調整することが可能である。例えば、先細短辺側の幅Ｂを、巻着過程におけるラベル１８の伸長又は蛇行の程度に合わせて適切に設定することにより、ラベル１８と外装枠１４，１６の凹部とをなるべく平行にして、デザイン性を損なうことを抑制することが可能である。 In the embodiment described above, the difference (= d1 + d2) between the width A on the short side and the width B on the tapered short side is set to d1 = d2 as shown in FIG. d1 and d2 can be arbitrarily adjusted. 4 (b) and 4 (c) are plan views showing other examples of labels according to the present invention. In FIG. 4B, d1> d2. In FIG. 4C, d2 = 0. The values of d1 and d2 can be adjusted based on, for example, quality control of the battery pack around which the label is wound. Further, the width B on the tapered short side can be arbitrarily adjusted. For example, the width B can be adjusted based on the quality control of the battery pack around which the label is wound. For example, by appropriately setting the width B of the tapered short side in accordance with the extent of extension or meandering of the label 18 in the winding process, the label 18 and the recesses of the exterior frames 14 and 16 are made as parallel as possible. It is possible to suppress impairing the design.
また、上述した実施の形態においては、先細部分をテーパ状にしているが、先細部分の形状はテーパ状に限定はされず、任意の先細形状にすることが可能である。図５は本発明に係るラベルの更に他の例を示す平面図であり、図６（ａ）、（ｂ）は図５に示すラベルを巻着した電池パックの例を示す表面図及び側面図である。図５に示すラベル１９の先細部分の長辺は平行であり、ラベル１９の長辺の一部分のみがテーパ状になっている。例えばＡ−Ｂ＝０．２ｍｍであり、各長辺から０．１ｍｍ細くなった先細部がラベル１９の一短辺側に形成されている。前記テーパ状になった一部分は、図６（ｂ）に示すように、巻着時は電池パックの側面に位置するように、位置合せ凸部１８ａが形成された部分から所定の間隔を空けた位置に形成されている。この場合、図６（ｂ）に示すようにラベル１９幅の変化は電池パックの側面部で生じており、図６（ａ）に示すように電池パックの表面部又は裏面部ではラベル１９の幅は一定であるため、ラベル１９の幅の変化は目に付き難く、デザイン性を損なうことなく、本発明の効果を得ることができる。 In the above-described embodiment, the tapered portion is tapered. However, the shape of the tapered portion is not limited to the tapered shape, and can be any tapered shape. 5 is a plan view showing still another example of the label according to the present invention, and FIGS. 6A and 6B are a front view and a side view showing an example of a battery pack around which the label shown in FIG. 5 is wound. It is. The long side of the tapered portion of the label 19 shown in FIG. 5 is parallel, and only a part of the long side of the label 19 is tapered. For example, AB = 0.2 mm, and a taper that is 0.1 mm thinner from each long side is formed on one short side of the label 19. As shown in FIG. 6B, the tapered portion is spaced from the portion where the alignment convex portion 18a is formed so as to be positioned on the side surface of the battery pack during winding. Formed in position. In this case, as shown in FIG. 6B, the change in the width of the label 19 occurs in the side surface portion of the battery pack. As shown in FIG. 6A, the width of the label 19 in the front surface portion or the back surface portion of the battery pack. Therefore, the change in the width of the label 19 is hardly noticeable, and the effects of the present invention can be obtained without impairing the design.
上述した実施の形態においては、外装枠の長辺にラベルを巻着したが、短辺にラベルを巻着することも可能である。なお、この場合は、保護回路基板１２は長辺側に配置される。また、上述した実施の形態においては、電池の側面を囲む枠状の外装体を例にして説明したが、電池全体を外装体で囲むことも可能である。 In the above-described embodiment, the label is wound around the long side of the exterior frame, but the label can be wound around the short side. In this case, the protection circuit board 12 is arranged on the long side. In the above-described embodiment, the frame-shaped exterior body that surrounds the side surface of the battery has been described as an example. However, the entire battery can be surrounded by the exterior body.
