[42] 所述旋转组件 24包括一旋转支座 241、 穿设在所述旋转支座 241中心的旋转轴芯 246、 联动所述旋转轴芯 246的一棘爪轮 242、 驱动所述棘爪轮 242运动的电机 243 。 本实施例中, 所述电机 243为一步进电机, 其通过一同步皮带 244带动一同步 皮带轮 245, 皮带轮 245的上部与所述棘爪轮 242固定连接。 这样, 当毛轮芯套 3 被套设在所述旋转轴芯 246顶部, 所述电机 243工作吋, 即可通过同步皮带 244带 动所述皮带轮 245转动, 从而通过棘爪轮 242联动所述旋转轴芯 246。
[43] 所述升降组件 25包括驱动所述毛条供给机构 21升降的一棘凸轮 251, 所述棘凸 轮 251呈圆盘状, 其径向外缘设有可与所述棘爪轮啮合的棘齿, 其轴向一侧设有 一凸轮面 252。 所述棘凸轮 251通过所述棘齿受所述棘爪轮 242的驱动。 当棘爪轮 242带动旋转轴芯 246转动吋, 棘凸轮 251也被联动, 并通过其凸轮面 252将毛条 供给机构 21顶起 (详见后述) 。 所述凸轮面 252驱动所述毛条供给机构 21的行程 等于旋转刷 S3的高度。 旋转刷 S3螺旋之间的距离可通过棘爪轮 242和棘凸轮 251 之间的传动比例来设定。
[44] 所述毛条供给机构 21的一侧被枢接固定, 其另一侧设有一摆动顶杆 211, 并通 过所述摆动顶杆 211与所述棘凸轮 251的凸轮面 252接触。 这样, 当所述棘凸轮 25 1通过所述摆动顶杆 211推动所述毛条供给机构 21时, 毛条供给机构 21即可作小 角度的摆动 (请对比参照图 6及图 7) , 实现梳状毛条 S2在卷绕过程中的上升动 作。
[45] 所述毛条供给机构 21包括一气动夹 212、 驱动所述气动夹 212向所述卷绕机构运 动的气缸 213 , 所述气缸 213被枢接固定。 这样, 当所述毛条供给机构 21接过所 述梳状毛条制作装置 1制作的毛条 S2吋, 就可通过所述气缸 213将毛条 S2准确送 至卷绕机构 22, 方便毛条 S2和毛轮芯套 3之间的焊接。
[46] 所述焊接机构 23包括悍接头 231、 焊接压头 232、 固定所述焊接头 231和焊接压 头 232的连接套 233、 以及驱动所述连接套 233上下运动的气缸 234, 在所述焊接 头 231和所述连接套 233之间设有一弹性构件 235。 当气缸 213将毛条 S2送至卷绕 机构 22时, 由于所述毛轮芯套 3具有一头部 31 , 气缸 234带动焊接压头 232下降即 可先将所述毛条 S2的一端和头部 31压在一起。 随后, 弹性构件 235收缩, 所述焊 接头 231即可将毛条 S2的一端和头部 31外缘熔接在一起。 焊接动作完成后, 气缸 234复位, 卷绕机构 22即可幵始对毛条 S2进行卷绕工作。 在卷绕过程中, 电机 24 3开始旋转, 每旋转 3-5周 (即毛条 S2完成一个螺旋的绕制工作) , 焊接机构 23对 卷绕成螺旋状的梳状毛条 S2的螺旋之间进行焊接一次。 本实施例中, 气缸 234可 以调得较低, 以便所述螺旋可以承受因为螺旋逐渐增高而逐渐增大的气缸压力 。 这样, 毛条 S2所形成螺旋的即被所述头部 31固定, 而螺旋之间也被焊接在了 一起, 从而完成了旋转刷 S3的制备工作。
[47] 为方便落料, 所述旋转刷卷绕装置 2还包括一落料机构 26, 所述落料机构 26包 括一带动所述旋转轴芯 246上下运动的落料气缸 261, 这样, 当落料气缸 261带动 所述旋转轴芯 246向下运动吋, 套设在所述旋转轴芯 246顶部的旋转刷 S3即脱落 , 完成落料动作。
[48] 本发明旋转刷的制造方法包括以下步骤, 先将多根单丝制作成梳状毛条, 然后 将所述梳状毛条卷绕成螺旋状并固定。 以下结合上述旋转刷制造设备作详细说 明。
[49] 请参照图 1至图 4, 先将多个丝轮 S上的多条单丝 S1分别穿设在所述一级、 二级 导丝杆 111、 112的导丝孔 113内, 多条单丝 S1的外端被所述单丝夹持机构 12夹持 住, 此时所述单丝熔接机构 13对所述多条单丝 S1进行熔接。 单丝 S1在悍接压头 1 31压接的位置连成一体并形成与单丝 S1相连为的梳状毛条 S2。 随后, 气缸 122带 动气动夹钳 121向单丝熔接机构 13方向运动。 当梳状毛条 S2在气动夹钳 121的推 动下运动至上切刀 142下方吋, 上切刀 142即可向下运动并切下梳状毛条 S2。 从 而, 完成了梳状毛条 S2的制作过程。
[50] 请参照图 5至图 7, 当毛条供给机构 21接过所述梳状毛条制作装置 1制作的毛条 S 2时, 就可通过所述焊接机构 23将具有头部 31的毛轮芯套 3和梳状毛条 S2的一端 焊接在一起。 当旋转组件 24带动毛轮芯套 3继续旋转时, 梳状毛条 S2即可被缠绕 在毛轮芯套 3上。 由于升降组件 25可同时驱动毛条供给机构 21上升, 所述梳状毛 条 S2即可以螺旋方式缠绕在毛轮芯套 3上, 在缠绕过程中, 被卷绕成螺旋状的梳 状毛条 S2的螺旋之间还可通过焊接机构 23叠加焊接在一起, 这样梳状毛条 S2即 被卷绕成为一旋转刷 S3。
[51] 请参照图 8, 为本发明的旋转刷的实施例一, 其是采用上述旋转刷制造设备和 旋转刷的制造方法制成的, 其包括多根呈放射状排列的刷毛, 所述刷毛位于一 个梳状毛条 S2上, 所述梳状毛条卷绕成螺旋状并固定。 当然, 所述梳状毛条 S2 还可以多于一个。

[53] 请参照图 12, 为本发明的旋转刷的实施例二, 其与实施例一的区别在于, 该旋 转刷还具备以刷柄 6, 所述旋转刷 S3的数量为多个, 并且旋转刷 S3的刷毛长度分 为两组, 该两种长度的刷毛间隔排列。 这种旋转刷用于电路板的除尘工作, 因 为电路板上通常具有很多元器件, 其表面凹凸不平。 由于本实施例的旋转刷 S3 的刷毛具有不同长度, 其被安装于传送带自动除尘或者手动除尘吋, 不会损伤 元器件。 同时, 本实施例还适用于清洁凸凹不平的精密仪器。
[54] 请参照图 13, 为本发明的旋转刷的实施例三, 其与实施例二的区别在于, 所述 旋转刷 S3呈锥台形状。 其适用于穴装结构的除尘工作。
[55] 本发明的牙刷包括至少一个具有上述结构的旋转刷 S3 , 请参照图 14, 为本发明 牙刷的实施例一, 所述牙刷还包括一用以固定所述旋转刷的刷柄 4, 所述旋转刷 S3的数量至少为一个, 并沿所述刷柄 4的长度方向排列, 其旋转轴的方向与所述 刷柄 4的长度方向一致。 所述旋转刷 S3可由软硅胶料制成, 这种牙刷适于儿童和 幼儿使用。
[56] 请参照图 15, 为本发明牙刷的实施例二, 所述牙刷还包括一用以支撑所述旋转 刷旋转的刷柄 5, 所述旋转刷 S3的数量为一个, 由于采用了上述旋转刷制造设备 和旋转刷的制造方法, 其刷毛排列均匀, 并且旋转刷 S3的螺旋卷绕均匀, 易于 提高生产效率。
[57] 请参照图 16, 为本发明牙刷的实施例三, 所述旋转刷 S3的数量为两个, 并沿所 述刷抦 5的长度方向排列, 其旋转轴的方向与所述刷柄 5的长度方向垂直。 本实 施例由于采用了两个旋转刷 S3, 其清洁下效率进一步提高。
[58] 以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发明的 精神和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本发明的保 护范围之内。
