技术领域
本公开涉及但不限于机械制造技术领域，具体而言，涉及但不限于一种齿片工装。
背景技术
随着5G的发展，产品的性能越来越强大，功耗越来越高，对结构件的散热能力也提出了更高的要求。传统的一体压铸成型的结构件，只能单纯通过加大产品外形，加高、加密散热齿来提升散热能力，已经不能满足5G产品当前和未来的需求。
而为了突破传统的一体压铸成型的结构件的限制，目前已有厂商采用了将齿和基板分开制造然后连接固定到一起的方法来达到增加散热效率和减小结构件整体重量的目的。但是，由于目前没有一种可以实现自动化安装散热齿片的工装结构，因此目前采用的方案是将高效的散热齿片手工安装到散热基板上。这种方案需要大量的人力操作，效率低下。
发明内容
本公开实施例提供一种齿片工装，主要解决的技术问题是：提供一种用于安装散热齿片的工装结构。

下面通过具体实施方式结合附图对本公开实施例作进一步详细说明。
实施例一：
参见图1所示，图1为本公开实施例提供的一种齿片工装的结构示意图，包括：连接体(1)，以及连接体(1)下连接的多个工装块体(2)。
需要说明的是，本实施例中的多个是指的两个或两个以上。在本实施例中，连接体(1)下连接有多个工装块体(2)以便将散热齿片安装到散热板上时，可以批量地将散热齿片安装到散热板上。需要说明的是，本实施例中所述的散热板包括但不限于传动的散热基板，还可以是有散热需要，需要安装散热齿片的壳体等构件。
在本实施例中，相邻两工装块体(2)之间应当留有用于安放散热齿片的间隙。需要说明的是，在本实施例中各工装块体(2)之间可以相互平行设置，例如图1所示的。且本实施例中各工装块体(2)之间间距可以相同。但应当理解的是，齿片工装的各工装块体(2)的设置形式(是否平行)以及各工装块体(2)之间的间隔不同所对应应用的散热板结构也不同，也即齿片工装的各工装块体(2)的设置形式以及各工装块体(2)之间的间隔是依据所要安装散热齿片的散热板的结构来决定。
在本实施例中，各工装块体(2)可以是和连接体(1)一体成型的；但是，各工装块体(2)和连接体(1)之间也可以采用可拆分结构连接。
在本实施例中，参见图2A和图2B所示，工装块体(2)上开有槽体(3)和抽气口(4)；其中：槽体(3)设置在工装块体(2)上，且槽体(3)的开口在工装块体(2)的贴合面上。需要说明的是，工装块体(2)的贴合面是指安放散热齿片时，工装块体(2)上会与散热齿片进行贴合的面。
而抽气口(4)是一个通孔，抽气口(4)从工装块体(2)的边沿贯通至槽体(3)。这样，参见图3所示，在安放散热齿片31后，散热齿片即会和槽体(3)一起配合形成空腔。之后，只需要使用抽气设备通过抽气口(4)即可对形成的空腔内的空气进行抽取，从而利用外部气压将散热齿片固定在工装块体(2)的贴合面上。
应当理解的是，本实施例中抽气口(4)可以与抽气设备连接以实现抽气。对于抽气设备的具体形式以及抽气设备与抽气口的连接方式在本实施例中不做限定，只要其可以实现通过抽气口(4)对散热齿片和槽体(3)一起配合形成的空腔进行抽气即可。在本实施例中，抽气开关可以设置在工装外，如抽气设备上，这样在安放好散热齿片到工装上时，只要人为打开该抽气开关即可实现抽气。但是在本实施例中也可以将抽气开关设置在工装上，如设置在齿片工装中与散热齿片的抵合位置处，这样在安放散热齿片到工装上时，散热齿片的抵合即会自动触发抽气开关打开，进行实现自动抽气。
在本实施例中，工装块体(2)的贴合面上可以设置限位凸台(5)，例如参见图2A和图2B所示。限位凸台(5)用于在安放散热齿片时，可以与散热齿片抵合以限制散热齿片的安放位置，例如参见图3所示。
需要说明的是，在本实施例中，也可以不设置限位凸台(5)，此时安放散热齿片到工装上时，散热齿片可以是抵合在连接体(1)的底部的，即可以通过连接体(1)的底部来实现对散热齿片的限位。
但是应当理解的是，在实际应用中可能存在对于同一版型的散热板所需安装的散热齿片不同的情况，例如，设某款散热器有A、B两种型号，对于A型号，采用的是散热板a加散热齿片1，而对于B型号，则采用的是散热板a加散热齿片2，而散热齿片1的尺寸小于散热齿片2。那么为了节约成本，本实施例中的一种可行实施方式中，可以设置限位凸台(5)，且限位凸台(5)是可拆卸连接，那么在安装限位凸台(5)时，即可用于安装散热齿片1；而在去掉限位凸台(5)时，即可用于安装散热齿片2。这样，即可通过一台工装实现这两种型号的散热器的散热齿片安装，而在不能设置限位凸台(5)的方案而言中，则需要两套齿片工装，在采用设置可拆卸的限位凸台的方案中，无疑极大的节约了成本。当然应当理解的是，在本考虑解决上述问题的情况下，本实施例中限位凸台(5)可以和工装块体(2)为一体成型结构。
需要说明的是，在本实施例中对于在工装块体(2)上开出的槽体(3)的形状等不做限定，其可以是规则形状，也可以是不规则形状(例如图2A所示)。在本实施例中，对于槽体(3)的大小理论上不做限定，只要其能在抽出空气后使得散热齿片不会从工装块体(2)上脱落即可。
在本实施例中，槽体(3)可以有一个，但也可以有多个。但是在有多个槽体时，各槽体应当都有至少一个抽气口与之相连以实现对槽体内的空气进行抽气。由于抽气口需要连接抽气设备，为了节约成本，本实施例的一种可行实施方式中，可以通过一个抽气口同时连通多个槽体。
在实际应用过程中，由于槽体(3)位置处的空气会被抽离，因此在槽体 (3)处的散热齿片部分，散热齿片位于贴合面一侧的气压会小于外部气压，这就会导致在有一股力会将槽体(3)处的散热齿片部分压向槽体(3)中，而在槽体(3)较大或散热齿片的硬度不足时，则可能会在安装过程中导致散热齿片变形。为了防止这一情况的出现，在本实施例中，可以在工装块体(2)的上设置矫形凸台(6)，例如图2A所示。需要说明的是，矫形凸台(6)应当设置于槽体(3)内，且矫形凸台(6)的顶面应当与工装块体(2)的贴合面位于同一平面，这样在安放散热齿片时，利用矫形凸台(6)的支撑，即可以有效降低出现散热齿片变形的可能性。在本实施例的一种可行实施方式中，可以将矫形凸台(6)设置在槽体(3)中心，或可以将多个矫形凸台(6)分布式的设置于槽体的各个位置。在本实施例的另一种可行实施方式中，矫形凸台(6)可以镂空，这样即可保证槽体(3)内的空气含量，从而可以保证在抽出空气后所产生的压力足够大。需要说明的是，前述两种可行实施方式可以单独实施，也可以应用在一起共同进行实施。需要说明的是，本实施例中矫形凸台(6)可以和工装块体(2)为一体成型结构，当然，也可以为可拆分连接。
在实际应用过程中，由于做工、后期运输时变形等问题，使得工装块体(2)的贴合面以及散热齿片的面并不一定都是完全平整的。因此在实际应用过程中，安放散热齿片时可能会存在散热齿片和槽体(3)不能形成一个密闭的空腔的情况，此时即无法通过抽气来使得散热齿片固定在工装块体(2)的贴合面上。为解决这一问题，在本实施例中，可以在工装块体(2)的贴合面上设置环形凹槽(7)，并在环形凹槽(7)内设置与环形凹槽(7)大小形状相同的弹性密封条(8)，并将槽体(3)设置于环形凹槽(7)所围合出的环形区域内，例如参见图2A所示。这样，在安放散热齿片时，散热齿片即会和弹性密封条(8)接触，进而利用弹性密封条(8)的弹性使得弹性密封条(8)内的环形区域密封。此时在抽气即可保证散热齿片可以固定在工装块体(2)的贴合面上。
在本实施例中，弹性密封条(8)可以采用硅胶等材料制成，即在本实施例的一种可行实施例中，可以采用硅胶密封条来作为弹性密封条。
在本实施例中，在将散热齿片固定到了齿片工装上之后，为保证可以将散热齿片顺利安装进散热板的齿槽中，可以在工装块体(2)下部设置一定的倾角的缺口。应当了解的是，对于散热板而言，齿槽两端具有凸起41，例如参见图4所示。利用该凸起41，在工装块体(2)下移过程中，凸起41沿工装块体(2)的缺口相对位移，由于凸起41具有厚度，在工装块体(2)下移过程中，凸起41即沿该缺口不断施加使得散热齿片和工装块体(2)分离的力，这就使得在工装块体(2)下移过程中散热齿片和槽体(3)分离，不能形成一个密闭的空腔，从而丧失压紧散热齿片到工装块体(2)的力，使得散热齿片和工装块体(2)分离。
在本实施例的一种可行实施方式中，参见图2A和图2B所示，工装块体(2)底部在贴合面一侧设有缺口，缺口上设有倾斜块(9)；倾斜块(9)的倾斜面自上而下沿远离贴合面的方向倾斜。其中，仍旧参见图2A和图2B所示，倾斜块(9)的一个面与可以工装块体(2)的贴合面齐平，一个面与可以工装块体(2)的底面齐平。需要说明的是，工装块体(2)的底面为将散热齿片安装到目标设备上时，工装块体(2)面向目标设备的一面。还需要说明的是，在本实施例中倾斜块(9)可以有多个，例如图2A和图2B所示的，此时这多个倾斜块(9)可以均匀设置在缺口上。当然本实施例中也可以仅设置一个倾斜块(9)，在一种设置方式中，可以设置倾斜块(9)的宽度和缺口的宽度相同。此外，本实施例中倾斜块(9)可以和工装块体(2)一体成型。
需要说明的是，本实施例中图1、图2A和图2B所示意的均是工装块体(2)仅设置一个面作为了贴合面的情况，但是在实际应用中，可以将相邻工装块体(2)之间的间隙按需求设计的更大一点，从而可以设计工装块体(2)的两个面均可作为贴合面，例如可以参见图2C所示。一个工装块体(2)上的每个贴合面的结构可以是相同的。
需要说明的是，在图2C所示的结构中，存在两个抽气口(4)，这两个抽气口(4)是分别对不同的两个贴合面负责的，相互之间互不关联。但是在本实施例中，在工装块体(2)的两个面均为贴合面时，为了降低开孔数量，节约成本，也可以只设计一个抽气口(4)，例如图2D所示，此时抽气口(4)会从工装块体(2)的边沿分别贯通至两个槽体(3)处，从而利用一个抽气口即可实现对两个贴合面上的散热齿片固定。但是特别需要注意的是，在图2D所示的结构中，在使用时需要同时在两个贴合面上都安放有散热齿片时才能实现对散热齿片的固定，若仅需要对一个面上的散热齿片进行固定，则使用时必须要将抽气口(4)在另一个贴合面上的开口封闭住，否则无法实现对散热齿片的固定。
在本实施例的另一种可行实施方式中，可以不设置倾斜块(9)，而是直接设计工装块体(2)底部在贴合面一侧自上而下沿远离贴合面的方向倾斜。
本公开实施例提供的齿片工装，包括：连接体(1)，以及连接体(1)下连接的多个工装块体(2)；相邻两工装块体(2)之间留有用于安放散热齿片的间隙；工装块体(2)上开有槽体(3)和抽气口(4)；其中：槽体(3)的开口在工装块体(2)的贴合面(贴合面为安放散热齿片时，工装块体(2)上与散热齿片贴合的面)上，而抽气口(4)则从工装块体(2)的边沿贯通至槽体(3)；这样，在安放散热齿片后，槽体(3)与散热齿片即会配合形成空腔，然后通过抽气口(4)抽出空腔内的空气即可使得散热齿片固定在工装块体(2)的贴合面上。这样，只需要进行安放好散热齿片的工装对应垂直压合到散热基板的齿槽上即可实现散热齿片的安装。由于齿片工装可以连接到自动化机械设备上，因此采用本实施例的齿片工装即为实现自动化的散热齿片的安装提供了可能。在齿片工装可以连接到自动化机械设备上时，通过各类对准技术(例如包括但不限于利用图像识别、位置感应、设计导柱和导套对准等技术)利用图像识别、位置感应等技术即可实现齿片工装与散热基板间的精确对准，从而实现散热齿片的自动化安装，可以节约人力成本，同时 提升安装效率。
此外，由于传统的安装过程必要通过人工来完成，因此散热齿片与齿槽之间的间隙较大，这就使得齿片易歪斜，需要再次调整位置；而散热齿片与齿槽之间的间隙大，也使得齿间距变化大，后工序固定工装工作时，易出现工装与齿片的干涉，导致齿片与基板之间无法有效固定连接；此外散热齿片与齿槽之间的间隙大，固定连接完成后，两者之间接触面积小，接触热阻大，影响散热。而采用本公开实施例提供的齿片工装进行安装时，可以实现自动化安装，因此散热齿片与齿槽之间的间隙可以完全按照匹配的尺寸设置，散热齿片与齿槽之间的间隙小，解决了散热齿片变形问题；同时由于散热齿片与齿槽之间的间隙小也避免了固定工装与齿片之间的干涉的问题，同时还减小了齿片与基板槽之间的接触热阻，提升了散热器的散热能力。
实施例二：
本实施例在实施例一的基础上，以图2A和图2B所示的结构为例对本公开的方案做进一步示例说明。
相关技术中，安装散热齿片的方案是通过人工手动进行安装，存在以下缺点：1、散热齿存在变形，手工放置齿片入槽困难，放置效率低；2、散热齿片与齿槽之间的间隙大，齿片易歪斜，需要手工调节或利用工装再次调整位置；3、散热齿片与齿槽之间的间隙大，齿间距变化大，后工序固定工装工作时，易出现工装与齿片的干涉，导致齿片与基板之间无法有效固定连接；4、散热齿片与齿槽之间的间隙大，固定连接完成后，两者之间接触面积小，接触热阻大，影响散热。
参见本公开实施例图2A和图2B所示，在工装上设计有槽体(3)、凹槽(7)和抽气口(4)，凹槽(7)中安放有硅胶密封条(8)，当散热齿片放入工装上时，触动抽气开关即可对工装、硅胶密封条和散热齿片之间形成的封闭腔体进行抽气，从而使散热齿片贴合在工装上。在工装的贴合面上分布设 置有限高矫形凸台(6)，矫形凸台(6)设置于槽体(3)内，可以实现对散热齿片的矫形，避免抽气之后散热齿片变形。此外，在工装上还设计有倾斜块(9)，在将散热齿片安装到基板上时，可以通过各类对准技术(例如包括但不限于利用图像识别、位置感应、设计导柱和导套对准等技术)实现散热齿片和基板上的齿槽的精准对齐。当散热齿片被放入到齿槽中后，工装继续下行，工装上的倾斜块(9)压迫齿槽边的凸起使其变形，从而将齿片固定连接在散热基板上。
采用本方案，散热齿片随着工装被放入到基板上的齿槽内，不需要额外调整齿片的位置，可以将散热齿片的放置和固定一次完成，提高放置散热齿片的精度、解决了散热齿片变形问题，减小了齿片与基板槽之间的接触热阻，避免了后工序固定工装与齿片之间的干涉，同时提升了散热器的散热能力。
应当理解的是，本公开中，各个实施例中的技术特征，在不冲突的情况下，可以组合在一个实施例中使用。每个实施例仅仅是本公开的具体实施方式。
以上内容是结合具体的实施方式对本发明实施例所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
