现有技术中，为保障洗衣机内筒的高速旋转，外筒一般采用耐阻燃、高强度的塑料，但是轴承组件一般采用金属材料。二者在注塑成型时，因材质不同，对工艺要求极为苛刻。在实际使用过程中，容易出现金属轴承组件从塑料外筒中脱出的问题。
为了提高塑料外筒与金属轴承组件之间的装配强度，防止金属轴承组件从塑料外筒中脱出，现有技术通常采用加装挡筋的方式提升洗涤设备的塑料外筒与金属轴承组件装配强度，以防止金属轴承组件从塑料外筒中脱出，从而减少由于金属轴承组件从塑料外筒中脱出而造成洗涤设备故障的发生。
但是，通过采用加装挡筋的方式以改善金属轴承组件容易从塑料外筒中脱出的问题，存在加工工艺复杂，以及该方法没有改善金属轴承组件与塑料外筒之间的结合性，在使用过程中，仍会出现金属轴承组件从塑料外筒中脱出的问题。

首先参照图1-3，对本发明的提升洗涤设备的塑料外筒与金属轴承组件装配强度的方法进行描述。
如图1-3所示，为解决通过采用加装挡筋的方式以改善金属轴承组件容易从塑料外筒中脱出的问题，存在加工工艺复杂，以及该方法没有改善金属轴承组件与塑料外筒之间的结合性，在使用过程中，仍会出现金属轴承组件从塑料外筒中脱出问题，本发明的提升洗涤设备的塑料外筒与金属轴承组件装配强度的方法包括：

在高频感应机对金属轴承组件预热时，高频感应线圈内产生极性瞬间变化的强大磁束，磁束会贯通整个被加热的金属轴承组件，在处于感应加热状态下的金属轴承组件的内部与感应加热电流相反的方向，产生相对应的强大涡电流。由于处于感应加热状态的金属轴承组件内存在电阻，因此产生强的焦耳热能，使处于感应加热状态的金属轴承组件温度迅速上升，从而达到预热金属轴承组件至设定温度的目的。
高频感应加热技术具有加热速率快、加热均匀，能在短时间内完成对物体的加热，易于与自动化设备拼接，以满足实际生产的高效应用。
基于上述高频感应技术的特殊性质，本发明采用高频感应机预热金属轴承组件至设定温度，一方面能够加快预热金属轴承组件的预热速率，以实现在较短时间内对金属轴承组件的预热，另一方面采用高频加热机预热金属轴承组件能够对金属轴承组件实现均匀加热，以提高对金属轴承组件的预热效果，此外，高频感应机也易于与其他自动化设备拼接，以实现自动化生产的需求。由此，采用高频感应机预热金属轴承组件至设定温度，能够实现对金属轴承组件快速、均匀地预热，以满足通过快速预热金属轴承组件至设定温度，有效改善注塑过程中塑料外筒与金属轴承组件之间的结合性，以提高塑料外筒与金属轴承组件之间注塑连接的强度，从而防止金属轴承组件从塑料外筒中脱出，同时结合高频感应机易于与其他自动化设备拼接的特点，满足实际生产的高效应用。
为了进一步更好的满足实际生产的高效应用，发明人对“采用高频感应机预热金属轴承组件至设定温度”这一工艺步骤进行了进一步的优化，以满足利用高频感应机预热金属轴承组件易于操作，同时可以实现精准控制。
如图3所示，在一种可能的实施方式中，“采用高频感应机预热金属轴承组件至设定温度”的步骤进一步包括：
S0111：控制机械手抓取金属轴承组件；
S0112：将金属轴承组件置于高频感应机中；
S0113：启动高频感应机将金属轴承组件预热至设定温度。
本发明通过将高频感应机与机械手拼接，并通过相关控制步骤，以提高实际生产的自动化程度，从而满足实际生产的高效应用。
在本实施例中，通过控制机械手抓取金属轴承组件，并将金属轴承组件置于高频感应机中，同时启动高频感应机将金属轴承组件预热至设定温度，一方面能够实现方便抓取金属轴承组件，另一方面以满足自动化生产的需要。
在一种可能的实施方式中，设定温度为40～60℃。
为了对通过在注塑前预热金属轴承组件以改善在注塑过程中塑料外筒与金属轴承组件之间的结合性，以提高塑料外筒与金属轴承组件之间注塑连接的强度的工艺进一步优化，发明人对“预热金属轴承组件至设定温度”这一工艺步骤中的预热温度进行了相关研究。
实验研究发现，基于金属轴承组件与塑料外筒自身材质的特点，在将金属轴承组件与塑料外筒注塑连接前，将金属轴承组件预热至40～60℃，能够改善在注塑过程中塑料外筒与金属轴承组件之间的结合性，且性能提升效果优异，较好的提高了塑料外筒与金属轴承组件之间注塑连接的强度。
在一种可能的实施方式中，设定温度与塑料外筒和金属轴承组件的材质的不同而不同。
由于每款洗涤设备的不同，其选用的塑料外筒和金属轴承组件也会有所差异，进而，不同的塑料外筒和金属轴承组件自身材质也不尽相同。不同材质的塑料外筒与不同材质的金属轴承组件在注塑连接前，金属轴承组件所适用的最佳预热温度也会略有差异，由此，本实施例中的设定温度也需要根据塑料外筒和金属轴承组件的材质的不同适当调整， 以实现优化通过预热金属轴承组件以改善在注塑过程中金属轴承组件与塑料外筒的注塑强度的效果。
在一种可能的实施方式中，高频感应机的输出频率为450～500kHZ。
基于高频感应加热技术自身特性，加热频率决定加热深度，加热频率越高，加热深度越浅，加热频率越低，加热深度越深。
发明人结合高频感应加热技术自身特性以及注塑工艺的实际生产需要，对“采用高频感应机预热金属轴承组件至设定温度”这一工艺步骤中高频感应机的输出频率进项了相关研究。
实验研究发现，结合高频感应加热技术自身特性、金属轴承组件自身材质的特性以及注塑工艺对金属轴承组件的预热工艺要求，将高频感应机的输出功率设置为450～500kHZ，以满足在将金属轴承组件与塑料外筒注塑连接前，预热金属轴承组件的工艺要求，能够改善在注塑过程中塑料外筒与金属轴承组件之间的结合性，且性能提升效果优异，较好的提高了塑料外筒与金属轴承组件之间注塑连接的强度。
在一种可能的实施方式中，高频感应机的输出频率与塑料外筒和金属轴承组件的材质的不同而不同。
由于每款洗涤设备的不同，其选用的塑料外筒和金属轴承组件也会有所差异，进而，不同的塑料外筒和金属轴承组件自身材质也不尽相同。不同材质的塑料外筒与不同材质的金属轴承组件在注塑连接前，在对金属轴承组件进行预热的过程中，所需高频感应机的输出功率也会有所差异。由此，本实施例中所采用的高频感应机的输出频率也需要根据塑料外筒和金属轴承组件的材质的不同适当调整，以满足改善不同材质的塑料外筒和金属轴承组件注塑强度的需求。
此外，通过研究，对于“预热金属轴承组件至设定温度”这一工艺步骤中所需要的加热方式，发明人也给出了其他技术方案。
在一种可能的实施方式中，采用加热炉预热金属轴承组件至设定温度。
采用加热炉预热金属轴承组件至设定温度，能够实现对金属轴承组件的预热，以改善在注塑过程中塑料外筒与金属轴承组件的结合性，从而提升洗涤设备的塑料外筒与金属轴承组件装配强度。
但是，采用加热炉预热金属轴承组件至设定温度，在此过程中，一方面存在对金属轴承组件加热不均匀的问题，另一方面也存在加热速率缓慢的问题，从而不仅影响后期塑料外筒与金属轴承组件的注塑强度，而且不利于实际生产的高效应用。
在一种可能的实施方式中，采用热水箱预热金属轴承组件至设定温度。
在热水箱中通过热水与金属轴承组件之间的热传递，以实现对金属轴承组件的预热，由此，采用热水箱预热金属轴承组件至设定温度，能够实现对金属轴承组件的预热，以改善在注塑过程中塑料外筒与金属轴承组件的结合性，从而提升洗涤设备的塑料外筒与金属轴承组件装配强度。
但是，采用热水箱预热金属轴承组件至设定温度，在此过程中，一方面热水箱中热水的温度会随着时间的延长而降低，由此在预热过程的后半阶段会使得预热温度不足，另一方面采用热水箱预热金属轴承组件还存在加热速率缓慢的问题，从而不仅影响后期塑料外筒与金属轴承组件的注塑强度，而且不利于实际生产的高效应用。
在一种可能的实施方式中，采用恒温室预热金属轴承组件至设定温度。
通过将金属轴承组件放置于恒温箱中，使得恒温箱与金属轴承组件之间产生热传递，以实现对金属轴承组件的预热效果。采用恒温室预热金属轴承组件至设定温度，能够实现对金属轴承组件的预热，以改善在注塑过程中塑料外筒与金属轴承组件的结合性，从而提升洗涤设备的塑料外筒与金属轴承组件装配强度。
但是，采用恒温室预热金属轴承组件至设定温度，在此过程中，通过热传递的方式预热金属轴承组件，加热速率缓慢，不利于实际生产的高效应用。
通过对比上述预热金属轴承组件所选用的不同的加热方式，可以发现采用高频感应机、加热炉、热水箱、恒温室均可实现预热金属轴承组件至设定温度的技术效果，以有效改善注塑过程中塑料外筒与金属轴承组件之间的结合性，从而提高塑料外筒与金属轴承组件之间注塑连接的强度，进而防止金属轴承组件从塑料外筒中脱出。
但是，通过比较这种加热方式，不难发现采用高频感应机预热金属轴承组件至设定温度，一方面能够实现对金属轴承组件快速、均匀的预热，另一方面能够满足实际生产的高效应用。与其他加热方式相比，优势更加突出。
综上所述，基于洗涤设备的塑料外筒与金属轴承组件的材质不同，在注塑过程中，对工艺要求极为苛刻。本发明通过预热金属轴承组件至设定温度后，再将塑料外筒与金属轴承组件注塑连接，能够改善塑料外筒与金属轴承组件之间的结合性，以提高塑料外筒与金属轴承组件之间注塑连接的强度，从而防止金属轴承组件从塑料外筒中脱出。
并且，基于高频感应技术自身优势和特点(对金属加热效果好，对塑料却无法加热)，高频感应机利用导体在高频磁场作用下产生的感应电流以及导体内磁场的作用，产生磁滞损耗引起导体自身发热以实现加热。
在高频感应机对金属轴承组件预热时，高频感应线圈内产生极性瞬间变化的强大磁束，磁束会贯通整个被加热的金属轴承组件，在处于感应加热状态下的金属轴承组件的内部与感应加热电流相反的方向，产生相对应的强大涡电流。由于处于感应加热状态的金属轴承组件内存在电阻，因此产生强的焦耳热能，使处于感应加热状态的金属轴承组件温度迅速上升，从而达到预热金属轴承组件至设定温度的目的。
基于上述高频感应技术的特殊性质，采用高频感应机预热金属轴承组件至设定温度，以实现快速预热金属轴承组件至设定温度，从而满足实际生产的高效应用。
此外，根据塑料外筒和金属轴承组件材质的不同选择不同的预热温度以及不同的高频感应机的输出温度，以满足改善不同材质的塑料外筒和金属轴承组件注塑强度的需求，从而优化通过预热金属轴承组件以改善金属轴承组件与塑料外筒的注塑强度的效果。
需要说明的是，上述实施方式仅仅用来阐述本发明的原理，并非旨在与限制本发明的保护范围，在不偏离本发明原理的条件下，本领域技术人员能够对上述结构进行调整，以便本发明能够应用于更加具体的应用场景。
此外，本领域的技术人员能够理解，尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本发明的保护范围之内并且形成不同的实 施例。例如，在本发明的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
