Description

物料组件及其成型方法、装配方法及发声装置模组 技术领域
本发明涉及自动装配技术领域，更具体地，本发明涉及一种物料组件及其成型方法、装配方法及发声装置模组。
背景技术
扬声器模组是便携式电子设备的重要声学器件，用于完成电信号与声信号之间的转换，是一种能量转换器件。扬声器单体将整个模组腔体分隔为前声腔和后声腔两个腔体。在后声腔腔体中，可以适当填充一些改善声学性能的材料，例如吸音棉。吸音棉能起到降低扬声器模组低频谐振频率，提高低频灵敏度，改善谐波失真，提升音频等作用。
目前，吸音棉的一侧表面通过双面胶贴合在底膜上。在将吸音棉装配到扬声器声腔时，通过人工使用镊子将吸音棉从底膜上剥离，再将吸音棉贴附到扬声器腔体中。该种装配方法存在以下问题：(1)人工贴附吸音棉效率低，人力成本较高；(2)吸音棉本身材质较为柔软、易损坏，在使用镊子将吸音棉从底膜上撕离时，容易对吸音棉造成损伤，影响吸音棉的使用效果。(3)人工贴附吸音棉时，吸音棉贴附位置的一致性较差，容易造成声学性能的一致性偏差。
因此，有必要对现有吸音棉或者类似的软质材料片的装配方法进行改进。

可选地，在所述底膜上冲裁出多个所述通孔，将与所述通孔数量一致的多个硬质支撑片分别放入所述通孔内；将一块整的软质材料片贴合到双面胶上之后，对整块的软质材料片进行冲裁，获得横截面积大于通孔的多个单独的软质材料片。
根据本发明的第三方面，提供了一种装配方法。该装配方法包括：提供支撑平台、位于支撑平台下方的顶出模组以及位于支撑平台上方的压紧模组和取放模组；提供上述物料组件；将物料组件放置于支撑平台上，软质材料片位于上方；压紧模组下移而且压紧底膜；顶出模组上移而且将硬质支撑片和粘接有双面胶的软质材料片一同顶起；取放模组抓取被顶起的软质材料片，将其装配于待装配器件中。
可选地，在所述支撑平台和底膜上分别设置有相匹配的定位柱和定位孔，在将所述底膜放置于所述支撑平台上时，所述定位柱穿入所述定位孔内；所述取放模组包括机械手和吸嘴，在软质材料片被顶起后，所述吸嘴吸取软质材料片，所述机械手带动所述吸嘴移动而且将软质材料片装配于待装配器件中。
可选地，软质材料片为吸音棉，所述待装配器件为发声装置模组；所述发声装置模组包括模组壳体和发声器件，所述发声器件将模组壳体内部空间分割为前腔和后腔；在抓取被顶起的吸音棉后，所述取放模组将吸音棉贴附于发声装置模组的前腔或后腔中。
可选地，所述压紧模组包括压紧件和用于带动所述压紧件往复移动的第一气缸，所述第一气缸带动所述压紧件朝向所述支撑平台的方向移动而且压紧所述底膜；所述顶出模组包括顶出件和用于带动所述顶出件往复移动的第二气缸，在所述支撑平台上设有与所述顶出件位置相对应的避让孔，所述第二气缸带动所述顶出件朝向所述支撑平台的方向移动而且将所述硬质支撑片和粘接有双面胶的软质材料片一同顶起。
根据本发明的第四方面，提供了一种发声装置模组。该发声装置模组包括模组壳体和发声器件，所述发声器件将模组壳体的内部空间分割为前腔和后腔，在所述前腔或后腔内贴附有吸音部件，所述吸音部件为上述物料组件中的软质材料片、双面胶和硬质支撑片的结合体，所述软质材料片为吸音棉，所述吸音部件通过硬质支撑片周边的双面胶贴附于所述前腔或后腔的内壁上。
本发明的发明人发现，现有吸音棉等软质材料片的装配方法中，软质材料片的一侧表面通过双面胶粘附在底膜上，通过人工使用镊子将软质材料片从底膜上剥离，再将软质材料片人工贴附到产品上。该种装配方法效率低，人力成本较高，容易对软质材料片造成损伤从而影响其使用效果。而且，人工贴附软质材料片的位置一致性较差。因此，本发明所要实现的技术任务或者所要解决的技术问题是本领域技术人员从未想到的或者没有预期到的，故本发明是一种新的技术方案。
本发明的发明人进一步发现，使用机器贴附软质材料片能够实现自动化装配。通过顶出工装和装配机器的配合能实现软质材料片与底膜的分离。但是，由于软质材料片的材质较为柔软，顶出工装在将其从底膜上顶出时会损坏软质材料片。
在本发明提供的一种物料组件及其成型方法、装配方法及发声装置模组中，软质材料片的横截面积大于底膜上通孔的横截面积。软质材料片通 过双面胶贴合于底膜的一侧表面上而且覆盖通孔，硬质支撑片位于通孔内而且粘接于双面胶上。硬质支撑片通过双面胶与软质材料片固定在一起，起支撑作用，便于使用机器将软质材料片装配于待装配器件中。
在将物料组件放置于支撑平台上之后，压紧模组压紧底膜。顶出模组上移而且将硬质支撑片和粘接有双面胶的软质材料片一同顶起，软质材料片从底膜上剥离。取放模组抓取被顶起的软质材料片，而且将软质材料片装配于待装配器件中。
该装配方法能将软质材料片自动装配在待装配器件中，从而提高作业效率，降低人力成本。
硬质支撑片位于软质材料片的底部。顶出模组将硬质支撑片和软质材料片一同顶起时，顶出模组直接与硬质支撑片相抵，避免了手工装配的镊子等尖锐工具触碰软质材料片，减少了对软质材料片的损伤，保证了软质材料片的使用效果。
取放模组将软质材料片自动装配于待装配器件中，能够保证软质材料片贴附位置的一致性。
通过以下参照附图对本发明的示例性实施例的详细描述，本发明的其它特征及其优点将会变得清楚。

该实施例中，参照图3，在所述支撑平台16上设有避让孔160。所述避让孔160与所述顶出件的位置相对应。所述避让孔160与所述通孔100的位置相对应。在所述第二气缸带动所述顶出件朝向所述支撑平台16的方向移动时，所述顶出件穿出所述避让孔160，穿入所述通孔100，而且将所述硬质支撑片11和粘接有双面胶12的软质材料片13一同顶起。
