除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
本申请的实施例首先提供如图1和图2所示的一种硅油供料和喷涂装置20，包括硅油上料组件100和检测件200。物料300内部中空形成容纳腔310，同时物料300的两端分别设置有连通容纳腔310内部和外部的进料口320和出料口330。进料口320的口径远小于出料口330的口径。物料300在夹持组件410夹持下随着移送装置400移动至硅油供料和喷涂装置20处。此时，进料口320位于物料300的下端，而出料口330位于物料300的上端，硅油上料组件100位于物料300下方。
参照图1和图2，硅油上料组件100包括储料器110、硅油泵120、供料管130、硅油管140、真空件150和硅化驱动件160。储料器110、硅油泵120、供料管130、硅油管140依次连通。储料器110用于存储硅油，硅油泵120用于输送硅油依次经过硅油泵120、供料管130和硅油管140后喷射而出。真空件150用于对储料器110进行抽真空处理。若是硅油中含有空气，则每次喷射的硅油中空气含量往往并不一致，从而导致每次喷射的硅油 含量并不一致，从而无法保障硅油在容纳腔310内壁分布的均匀性。因此，利用真空件150对储料器110抽真空的方式，减少硅油中含有的空气，从而使得每次喷射的硅油含量尽可能一致，从而提升硅油在容纳腔310内壁分布的均匀性。硅油管140在硅化驱动件160的作用下能够通过进料口320移动并进入容纳腔310以及离开容纳腔310。硅油管140在硅化驱动件160作用下经过第一移动区间和第二移动区间。第一移动区间位于容纳腔310外部，第二移动区间位于容纳腔310内部。硅油管140在第一移动区间的移动速度大于硅油管140在第二移动区间的移动速度。当硅油管140在第二移动区间移动时，硅油管140往物料300内部的容纳腔310内壁喷射硅油以使得物料300内部发生硅化。该硅油供料和喷涂装置20能够对物料300内部进行硅化处理，减少物料300在推拉过程中的摩擦阻力。硅油需要尽可能在容纳腔310内壁均匀分布才能够起到良好的硅化效果。因此，若是硅油上料组件100移动至最高点再喷射硅油，依靠硅油在自身重力作用下分布在容纳腔310内壁，一方面容纳腔310内壁的硅油分布不够均匀，另一方面速度过慢，不利于提高产能。因此，硅油上料组件100在第二移动区间移动的同时进行喷射硅油能够提升硅油在容纳腔310内壁分布的均匀性，加快生产效率。但同时，若是硅油上料组件100在容纳腔310移动速度过快，一方面，喷射的硅油较少，无法达到生产要求，另一方面，硅油上料组件100移动到位时，难以同时停止喷射硅油，从而也会导致硅油在容纳腔310内壁分布不够均匀。因此，控制硅油上料组件100在第二移动区间时速度较慢，则硅油上料组件100既能够喷射足够的硅油，又能够在移动到位的同时停止喷射硅油，从而保障硅油在容纳腔310内壁分布的均匀性。控制硅油上料组件100在第一移动区间时速度较快，则能够保障整体运行时间不变。在图1所示的具体实施方式中，供料管130采用柔性材料制作，从而避免供料管130影响硅油管140和硅油泵120在硅化驱动件160作用下发生移动。硅油泵120采用微量泵，从而能够实现对硅油喷射量的定量控制。硅化驱动件160采用气缸。
在一些实施方式中，参照图5，储料器110、供料管130、硅油泵120、硅油管140依次连通，以使得硅油泵120和硅油管140直接连通，从而缩短硅油泵120和硅油管140之间的距离，避免因为硅油泵120和硅油管140之间供料管130过长导致定量的硅油因为阻力过大而无法全部从硅油管140喷出，从而解决硅油管140喷射的硅油量不够精准的问题。同时，硅油管140位于物料300的下方，硅油在硅油管140中是从下往上移动，因此硅油在硅油管140中移动需要克服自身重力作用，阻力更大。而硅油泵120和硅油管140直接连通，使得硅油经过硅油泵120之后有足够的动力克服自身重力以在硅油管140中向上移动至从硅油管140喷出，从而解决硅油管140喷射的硅油量不够精准的问题。此时，硅油泵120位于硅化驱动件160和硅油管140之间，起到连接硅化驱动件160和硅油管140的 作用。
在一些实施方式中，参照图5，当需要同时对多个物料进行硅化处理时，则需要多根硅油管140。此时，硅油上料组件100还包括废料盒170。多根硅油管140同时穿过废料盒170的底部并和废料盒170固定连接。此时，若是硅油管140或者物料出现硅油掉落的情况时，硅油能够掉落在废料盒170中，避免对引起设备污染。
参照图2，硅油管140的轴心线和容纳腔310的轴心线之间夹角为α，并且α满足以下条件：0≤α≤30°。具体的，α可以为0、5°、10°、20°、30°。硅油管140尽可能以硅油管140的轴心线平行于容纳腔310轴心线的状态进入容纳腔310，从而硅油管140到容纳腔310内壁的距离沿着硅油管140的轴向尽可能保持相同，从而提高硅油在容纳腔310内壁分布的均匀性。
参照图3和图4，硅油管140包括内管141、包裹内管141的外管142和引导件143。内管141作为硅油移动的液体通道，内管141包括位于内管141的端部以使得硅油离开内管141的出液口141a。外管142和内管141之间形成气体通道，引导件143位于气体通道内，外管142包括位于外管142的端部以使得气体离开外管142的出气口142a。引导件143内部设置有螺旋孔，因此气体经过引导件143的引导后在气体通道中发生螺旋移动。出液口141a位于外管142的内部，出气口142a向外管142的轴心线汇聚。气体可以采用空气或者惰性气体。经过引导件143引导后气体发生螺旋移动，同时，出液口141a又位于外管142的内部，从而螺旋移动的气体会经过出液口141a。而气体经过出液口141a时会带动硅油移动，使得硅油发生雾化，从而使得从出气口142a离开的硅油能够在气体带动下更加均匀地喷射至容纳腔310内壁。
参照图2，检测件200采用传感器，传感器和物料300在水平面内的投影错位分布。传感器根据硅油上料组件100喷射硅油前后物料300不同的折射率检测容纳腔310是否存在硅油。在图2所示的具体实施方式中，传感器采用折射传感器。
本申请另外提供如图6所示的一种医疗器械生产线10，包括清洗装置500、干燥装置600和上述任一实施例的硅油供料和喷涂装置20。物料300在夹持组件410夹持下随着移送装置400先后移动至清洗装置500、干燥装置600和硅油供料和喷涂装置20。清洗装置500包括内部清洗组件510。内部清洗组件510位于物料300下方。内部清洗组件510通过进料口320往物料300内部的容纳腔310喷射清洗液以实现对物料300内部进行清洗。清洗液可以为水或者注射液。干燥装置600用于对经过清洗之后的物料300进行干燥处理。采用该硅油供料和喷涂装置20的医疗器械生产线10具有稳定可靠的效果。物料300进行硅化处理之前需要先进行清洗处理和干燥处理。清洗液能够在自身重力作用下从进料口 320离开容纳腔310，从而能够加快物料300的干燥，缩短物料300在干燥装置600的加工时间，提高干燥效果，从而使得物料300能够尽快进行硅化处理，保障硅化效果。因此，硅油管140也需要位于物料300的下方，才能够从进料口320进入容纳腔310，实现对物料300内部的硅化处理。
参照图6，内部清洗组件510包括内喷管511和驱动内喷管511移动的清洗驱动件512。内喷管511在清洗驱动件512的作用下能够通过进料口320移动并进入容纳腔310以及离开容纳腔310。内喷管511在清洗驱动件512作用下也经过第一移动区间和第二移动区间。内喷管511在第一移动区间的移动速度和内喷管511在第二移动区间的移动速度相同。当内喷管511在第二移动区间移动时，内喷管511往物料300内部的容纳腔310内壁喷射清洗液。在图6所示的具体实施方式中，清洗驱动件512采用气缸。内喷管511的轴心线和容纳腔310的轴心线之间存在夹角β，并且β满足以下条件：0≤β≤30°。具体的，β可以为0、5°、10°、20°、30°。内喷管511尽可能以内喷管511的轴心线平行于容纳腔310的轴心线的状态进入容纳腔310，从而内喷管511到容纳腔310内壁的距离沿着内喷管511的轴向尽可能保持相同，从而提高内喷管511喷射至容纳腔310内壁的清洗液在容纳腔310内壁的均匀度，从而使得容纳腔310内壁的表面清洗效果尽可能相同。
以上所述实施方式的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施方式中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
本技术领域的普通技术人员应当认识到，以上的实施方式仅是用来说明本申请，而并非用作为对本申请的限定，只要在本申请的实质精神范围内，对以上实施方式所作的适当改变和变化都落在本申请要求保护的范围内。
