Description

晶体管的成型装置 技术领域
本申请涉及工装技术领域，尤其涉及一种晶体管的成型装置。
背景技术
晶体管在安装使用之前需要对其引脚成型。通常是采用手工折弯方式：将晶体管置于工作台的成型位置，使晶体管的引脚悬空，然后手工冲压晶体管的引脚，使引脚折弯成型。在上述成型过程中，由于晶体管的引脚整体受力，在折弯过程中引脚会拉扯晶体管的本体，导致引脚从本体中脱开或者本体内的芯片受损。另外，手工折弯的效率较低；而且由于施加的冲压力不够稳定，容易导致压制变形，批量成型的精度也不一致。
申请内容
有鉴于此，本申请提供了一种晶体管的成型装置，能够避免成型过程中晶体管受损，并且成型高效、成型精度一致性好。
一种晶体管的成型装置，所述晶体管包括本体和与所述本体相连的引脚，所述成型装置包括机台，所述机台上设有转料仓、定位件、夹持件、凹模和凸模；所述转料仓用于容纳所述本体，所述转料仓底部设有仅能使所述引脚伸出的缝隙，所述转料仓具有入料口和出料口，所述入料口与所述出料口分布在所述缝隙延伸方向上的相对两端，所述转料仓在所述机台上倾斜设置，以使所述转料仓中的所述晶体管在重力作用下从所述入料口传送到所述出料口；所述定位件可移动至贴合所述出料口的位置以将所述出料口堵塞，以对所述出料口处的所述晶体管进行限位；所述夹持件与所述凹模均设于所述出料口处，且分布于所述出料口的两侧；所述凹模位于所述定位件下方，所述凹模包括夹持座和位于所述夹持座下方的凹模座，所述夹持座与凹模座之间具有模腔；所述夹持座与所述夹持件可相向移动，以对称夹持在所述引脚的根部两侧；所述凸模设于与所述夹持件同侧的所述出料口处，所述凸模位于所述夹持件下方且对应所述模腔设置，所述凸模可向所述模腔移动以将所述引脚的头部朝所述模腔内折 弯。
其中，所述成型装置还包括与所述转料仓可拆卸地平行对接的物料盒，所述物料盒与所述入料口连通。
其中，所述转料仓内设有对所述晶体管进行滑行导向的导轨。
其中，所述夹持座与所述凹模座一体成型。
其中，所述夹持座与所述凹模座相互独立且活动连接。
其中，用于成型所述引脚的折弯内角的所述夹持座的一边具有第一圆角。
其中，用于成型所述引脚的折弯外角的所述凸模的一边具有第二圆角。
其中，所述成型装置还包括设在所述机台上的控制装置，所述控制装置用于控制所述定位件、所述夹持件、所述凹模及所述凸模的运动。
因此，本申请的成型装置，通过设置倾斜布置的转料仓，使得晶体管能够在重力作用下传送至出料口，实现了自动送料；通过设置定位件，能够对待成型的晶体管进行限位；通过设置可对称夹持在引脚的根部的夹持件与夹持座，能够在成型之前先将引脚的根部夹固，使得凸模冲压引脚的头部时，不会拉扯引脚的根部，从而防止与所述根部相连的本体受拉而损坏。并且，由于本定位装置采用机械方式送料和加工成型，因而成型效率高；依靠凸模施加冲压力，因而冲压力十分稳定且灵活可调。因此本定位装置的成型精度高、成型精度一致性良好，不会产生压制变形的异常。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例是本申请的一部分实施例，而不是全部实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本申请保护的范围。
本申请以下实施例提供了一种晶体管的成型装置，用于对晶体管的引脚进行折弯成型。如图1所示，在本第一实施例中，晶体管10包括本体101和引脚102，本体101与引脚102相连。所述成型装置可以批量进行晶体管10的成型。但是应理解，本成型装置不仅限于成型晶体管10，实际上本成型装置还可以用于其他带引脚器件的成型。
如图2和图3所示，本第一实施例的成型装置11包括机台110。机台110上设有转料仓120、定位件130、夹持件160、凹模140和凸模150。机台110作为成型装置11的承载机构和动力控制中枢，能够对成型装置11的其他部件进行运动控制。
如图2所示，转料仓120倾斜设置在机台110上，其与机台110的台面呈一夹角θ。转料仓120用于装载晶体管10。具体的，转料仓120内容纳有晶体管10的本体101，而晶体管10的引脚102伸出在转料仓120外。转料仓120底部设有缝隙(图未示)，所述缝隙的尺寸能使装入的引脚102伸出，但将本体101卡设在转料仓120内。使引脚102伸出到转料仓120外，是为了便于后续对引脚102进行折弯成型。转料仓120具有入料口121和出料口122，晶体管10从入料口121装入，在出料口122处进行成型并脱离。设置所述夹角θ，能够使得转料仓120中的晶体管10在重力作用下，从入料口121自动传送到出料口122。本实施例中，优选的，所述夹角θ为45°。在其他实施例中，可以根据实际需要设定所述夹角θ的具体数值。
本实施例中，转料仓120内设有导轨(图未示)，所述导轨用于在晶体管10滑行时起导向作用。在其他实施例中，也可以不设所述导轨，晶体管10直接在转料仓120内滑动，类似订书针在订书机的针匣内平移的结构。转料仓120可以是由左右对称的两部分对盒而成，此种结构便于制造；转料仓120也可以直接一体成型。
如图3和4所示，定位件130可移动地设在机台110上。定位件130可以移动到正对出料口122的位置，且定位件130的一个表面贴合在出料口122上，将出料口122堵塞，使得出料口122处的晶体管10无法继续移动。定位件130贴合在出料口122上时，其表面会接触本体102以将本体101“挡住”，而引脚102则悬空。从而，定位件130起到限位作用，以便于后续对引脚102进行成型。在完成一批次的成型之后，定位件130又能够回退到初始位置而不再堵塞出料口122，使已经成型的晶体管10从出料口122脱落。下一批次待成型的晶体管10会前移至出料口122处等待成型，而定位件130又将重复下一个成型周期内的往复运动。
本实施例中，定位件130开始就与出料口122在水平方向对应，定位件130水平平移即可将出料口122堵塞。此种设计中，定位件130的移动路径短、机构设计比较简洁。在其他实施例中，定位件130只需要能移动到堵塞出料口122的位置即可，而无需限制定位件130的初始位置。例如，定位件130开始就与出料口122在垂直方向上对应，定位件130竖直平移以将出料口122堵塞。
如图3-图5所示，夹持件160和凹模140均设在出料口122处，且分布在出料口122两侧。
其中，凹模140位于定位件130下方，即凹模140对应引脚102，便于对引脚102进行成型。凹模140包括夹持座143和位于夹持座143下方的凹模座141。夹持座143和凹模座141之间具有模腔142，用于对引脚102进行成型。如图5所示，夹持座143可移动贴合在引脚102的根部一侧，以在这一侧将引脚102的根部夹持住。
本实施例中，凹模140是一体成型，夹持座143和凹模座141连接为一体，当夹持座143移动时，凹模座141也随之移动。一体成型的设计结构简单、容易加工。在其他实施例中，夹持座143与凹模座141各自独立，两者可活动连 接，且夹持座143与凹模座141可分别单独移动。此种设计便于对夹持座143或凹模座141单独进行加工位置调整。或者，在其他实施例中，夹持座143与凹模座141各自独立且两者可活动连接，但是夹持座143可发生移动而凹模座141固定。
夹持件160分布在出料口122处与夹持座143相对的一侧。如图5所示，在夹持座143移动以夹持在引脚102的根部一侧的同时，夹持件160也向夹持座143移动而贴合在引脚102的根部另一侧，以在这一侧将引脚102的根部夹持住。此时，夹持件160与夹持座143对称夹持在引脚102的根部两侧，从而将引脚102的根部稳固地夹持，便于凸模150冲压引脚102。
如图3、4、5和7所示，凸模150设在与夹持件160同侧的出料口122处，凸模150位于夹持件160下方且对应模腔142的位置。当夹持件160与夹持座143将引脚102的根部夹持住后，凸模150向模腔142移动，通过凸模150与夹持座143的共同作用，将引脚102的头部朝模腔142内折弯，使引脚102成型。由于引脚102的根部已被稳固夹持，所以引脚102的头部折弯时，将不会拉扯到引脚102的根部，进而不会使与所述根部相连的本体101受拉而损坏。
引脚102折弯时会形成折弯内角与折弯外角。如图6和图7所示，夹持座143能够成型所述折弯内角，凸模150能够成型所述折弯外角。如图6所示，本实施例中，夹持座143上用于成型所述折弯内角的一条边具有第一圆角144，凸模150上用于成型所述折弯外角的一条边具有第二圆角151。设置此两个圆角有利于引脚102在折弯时的应力均匀释放，避免将引脚102折断。第一圆角144与第二圆角151的数值为相同或不同，两者的具体数值可以根据具体情况而定。
本实施例中，机台110上设有控制装置(图未示)，所述控制装置用于控制定位件130、夹持件160、凹模140及凸模150的运动。例如，所述控制装置能控制定位件130向限位晶体管10的位置移动，同时检测定位件130的位置。在检测到定位件130移动到位后，所述控制装置控制夹持件160与凹模140相向移动，以将引脚102的根部夹持。在检测到夹持件160与凹模140移动到位后，所述控制装置又控制凸模150向模腔142移动以进行冲压折弯。在 检测到引脚102已经折弯到位后，所述控制装置控制凸模150、夹持件160、凹模140与定位件130回移到初始位置，将引脚102松开，使引脚102从出料口122从脱落。
由此，本第一实施例的定位装置11，通过设置倾斜布置的转料仓120，使得晶体管10能够在重力作用下传送至出料口，实现了自动送料；通过设置定位件130，能够对待成型的晶体管10进行限位；通过设置可对称夹持在引脚102的根部的夹持件160与夹持座143，能够在成型之前先将引脚102的根部夹固，使得凸模150冲压引脚102的头部时，不会拉扯引脚102的根部，从而防止与所述根部相连的本体101受拉而损坏。并且，由于本定位装置11采用机械方式送料和加工成型，因而成型效率高；冲压力依靠凸模150施加，因而十分稳定且灵活可调，因此本定位装置11的成型精度高、成型精度一致性良好，不会产生压制变形的异常。
如图8所示，在本申请第二实施例中，与上述实施例不同的是，定位装置21还包括一个物料盒210。物料盒210与转料仓120平行对接且可拆卸，物料盒210与入料口121连通，物料盒210中盛装有晶体管10。将物料盒210对接到入料口121处后，晶体管10将在物料盒210中滑行，从物料盒210进入转料仓120，进而到达成型位置。本实施例中，物料盒210内部也可以设置导轨，便于对晶体管10进行滑行导向。当一个物料盒210中的晶体管10全部进入转料仓120时，可以将空的物料盒210拆卸，而重新将另一个装满晶体管10的物料盒210对接到转料仓120。物料盒210起到类似手枪中的“弹夹”的作用，其可以重复装填和更换。而在此更换的过程中，由于转料仓120还存在未成型的晶体管10，因此定位装置21仍然会处于加工状态，而不会闲置空转。因此，本第二实施例中，通过设置可更换的物料盒210，提高了成型设备的利用率，提升了加工效率。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易的想到各种等效的修改或替换，这些修改或替换都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
