图 3是根据本发明的实施例 2的研磨装置的结构示意图。
具体实施方式 现在对本发明的实施例进行详细的描述， 其示例表示在附图中， 其中，相 同的标号始终表示相同部件。下面通过参照附图对实施例进行描述以解释本发 明。 在附图中， 为了清晰起见， 可以夸大层和区域的厚度。 在下面的描述中， 为了避免公知结构和 /或功能的不必要的详细描述所导致的本发明构思的混淆， 可省略公知结构和 /或功能的不必要的详细描述。 实施例 1 如图 2所示， 根据本发明的实施例的研磨装置 200包括： 研磨带 210、 带 传动机构 220和带按压机构。 其中， 研磨带 210的数量为一根， 带按压机构包 括上带按压机构 231和下带按压机构 232。 具体而言，在对面板 300进行研磨时，将研磨带 210穿进上带按压机构 231 与面板 300的上表面 310之间形成的研磨间隙和下带按压机构 232与面板 300 的下表面 320之间形成的研磨间隙， 以使研磨带 210覆盖于面板 300的上表面 310和下表面 320; 启动传动机构 220运转以带动研磨带 210转动； 上带按压 机构 231和下带按压机构 232均可通过各自连接的伺服导轨 240来实现上下移 动，进而以控制是否将研磨带 210按压于面板 300的上表面 310和下表面 320， 以使研磨带 210对面板 300的两面同时进行研磨。 其中， 当上带按压机构 231 和下带按压机构 232控制将研磨带 210按压于面板 300的上表面 310和下表面 320时， 带传动结构 220使得研磨带 210绷紧， 并带动研磨带 210的转动， 进 而使得研磨带 210同时研磨面板 300的上表面 310和下表面 320; 当研磨结束 后， 上带按压机构 231和下带按压机构 232在各自连接的伺服导轨 240的控制 下远离面板 300而退开， 在这个过程中， 研磨带 210在带传动机构 220的作用 下， 继续保持绷紧状态。 在本实施例中，带传动机构 220是由多个转轮构成的，以实现上述的功能。 具体来说， 该带传动机构 220包括四个夹持轮 221、 222、 223、 224和四个从 动轮 225、 226、 227、 228。 其中， 第一夹持轮 221和第二夹持轮 222分别固定 设于上带按压机构 231的左右端， 第三夹持轮 223和第四夹持轮 224分别固定 设于下带按压机构 232的左右端， 并且第一夹持轮 221和第三夹持轮 223相对 设置，第二夹持轮 222和第四夹持轮 224相对设置，这样使得该四个夹持轮 221、 222、 223、 224分别位于面板 300的上表面 310和下表面 320的左右端。此外， 在本实施例中， 可将四个夹持轮 221、 222、 223、 224中的任意两个设为主动 轮， 该处所指的主动轮是可以通过自身装载的制动装置（例如， 电机等）而自 主地转动， 进而带动其它的夹持轮以及四个从动轮进行转动， 从而带动研磨带 210转动， 为了使得带传动机构 220能够有足够的传动动力来带动研磨带 210， 使得研磨带 210能够匀速转动， 进而使得研磨带 210对面板 300的上表面 310 和下表面 320以均匀的力来进行研磨， 优选地， 将第四夹持轮 224以及与第四 夹持轮 224对角设置的第一夹持轮 221均设为主动轮。 此外， 将四个从动轮 225、 226、 227、 228两两分组， 以形成两个从动轮 组， 在本实施例中， 将第一从动轮 225和第二从动轮 226组合形成为第一从动 轮组并设于面板 300的左侧， 将第三从动轮 227和第四从动轮 228组合形成为 第二从动轮组并设于面板 300的右侧。 其中， 四个从动轮 225、 226、 227、 228 分别由一个气缸 250控制， 可在各自被控制的气缸 250的行程方向上进行移动 调整， 当设为主动轮的第四夹持轮 224和第一夹持轮 221 自主地转动， 并带动 其它的夹持轮和四个从动轮转动时，通过各个气缸 250的自身调节使得各个从 动轮将研磨带 210绷紧。 当需要更换研磨带 210时， 可通过调节各个气缸 250 使得各个从动轮朝向面板 300移动， 进而使得研磨带 210松弛， 人员进行手动 更换。 此外， 在本发明中， 也可将上述的四个夹持轮 221、 222、 223、 224中的 任意一个夹持轮设为主动轮， 该设为主动轮的夹持轮可通过自身装载的制动装 置 （例如， 电机等）而自主地转动， 进而带动其它的夹持轮以及四个从动轮进 行转动， 从而也可带动研磨带 210转动。 在实际应用中， 上述设为主动轮的第一夹持轮 221和第四夹持轮 224的材 质均采用陶瓷， 由于陶瓷为绝缘体， 可避免由于自身装载的制动装置发生漏电 而引发的事故， 提高安全可靠性。 而且， 由于其它的非主动轮的夹持轮和从动 轮是通过摩擦力来提供给研磨带 210转动的动力， 因此， 本实施例的非主动轮 的夹持轮和从动轮的材质均为金属， 并且在金属外围包裹有橡胶， 以提高采用 非主动轮的夹持轮和从动轮与研磨带 210之间的摩擦力。 实施例 2 作为另一个可选的实施例， 如图 3所示， 与图 2所示不同的是， 上述的第 一从动轮组可只包括一个从动轮 229a， 该从动轮 229a的直径要大于面板 300 的厚度， 以达到上述的第一从动轮组所产生的效果。 同样地， 上述的第二从动 轮组也可只包括一个从动轮 229b， 该从动轮 229b的直径也要大于面板 300的 厚度， 进而达到上述的第二从动轮组所产生的效果。 综上所述， 由于只使用一根研磨带对面板的上表面和下表面同时进行研 磨， 因此减少一次研磨周期耗用的研磨带数量， 节约了生产成本， 而且一根研 磨带同时转动， 使得研磨带对面板的上表面和下表面施加均匀的力， 提高面板 的两表面的平整度。
尽管已经参照其示例性实施例具体显示和描述了本发明， 但是本领域的技 术人员应该理解， 在不脱离权利要求所限定的本发明的精神和范围的情况下， 可以对其进行形式和细节上的各种改变。
