具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例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公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
目前，通常采用厚度检测装置对背光源的厚度进行检测，该厚度检测装置中设置有卡槽结构，该卡槽结构包括通槽，该通槽的宽度与待检测的背光源的设计厚度(即设计尺寸)匹配。当待检测的背光源的边缘能够穿过该通槽时，该待检测的背光源的厚度符合设计厚度；当待检测的背光源的边缘无 法穿过该通槽时，该待检测的背光源的厚度不符合设计厚度。
本申请的发明人在研究中注意到，在利用厚度检测装置对背光源的厚度进行检测的过程中，背光源的边缘与厚度检测装置中的卡槽结构产生摩擦，随着厚度检测装置的检测次数的增加，卡槽结构可能会被磨损，导致该卡槽结构包括的通槽的宽度增大，从而导致后续的检测精度较低。
本公开实施例提供了一种厚度检测装置。请参考图1、图5至图7，这些图示意性地示出了本公开实施例提供的厚度检测装置的结构，该厚度检测装置92可以包括基座10、卡槽组件20和驱动组件30，该卡槽组件20和驱动组件30均设置在基座10上。
该基座10的侧壁10c上设置有通槽11，该通槽11贯穿基座10。例如，该通槽11沿基座10的厚度方向贯穿该基座10。由于基座在厚度方向上的尺寸较小，通过使通槽11沿厚度方向贯穿基座10，有利于提高待检测件的边缘穿过通槽11以及卡槽21的速度，即提高厚度检测效率。在其它实施例中，也可以使通槽11贯穿其它基座10的长度方向或宽度方向。
为了更清楚的看出基座10上设置的通槽11的结构，请参考图2，图2是本公开实施例提供的厚度检测装置92中基座10的结构示意图。如图1和图2所示，该通槽11与基座10的侧壁10c连通，也即是，通槽11的开口面位于基座10的侧壁10c上。需要说明的是，基座10包括设置有卡槽组件20的第一安装面10a，基座10的侧壁10c为基座10包括的位于第一安装面10a边缘所在侧的面；基座10还包括与第一安装面10a相对的面10b，通槽11贯穿第一安装面10a和与第一安装面10a相对的面10b，并且通槽11在侧壁10c处形成有开口(即通槽11与侧壁10c连通)。
该卡槽组件20具有n个卡槽21，n为大于1的整数，在本公开实施例中，该n个卡槽的尺寸可以均相同，每个卡槽21的宽度d1小于通槽11的宽度d2。在本公开实施例中，每种类型的背光源(同一类型的背光源的设计厚度相同)对应一种宽度的卡槽，在检测不同类型的背光源时，更换厚度检测装置中的卡槽组件20，以使该卡槽组件20中的卡槽21的宽度与待检测的背光源的厚度匹配。若采用该厚度检测装置检测背光源的厚度，通槽11与卡槽组件20中的一个卡槽21连通，也即是该卡槽21的开口与通槽11的开口朝向相同，当背光源的边缘能够穿过该卡槽21时，该背光源的厚度符合设计厚度 (即设计尺寸)；当背光源的边缘无法穿过该卡槽21时，该背光源的厚度不符合设计厚度。需要说明的是，背光源的边缘穿过卡槽21，是指：该边缘的一端卡槽的一端(卡槽的该一端位于面10a和10b中的一个)进入卡槽21中，并且该边缘在卡槽21内移动直至该边缘的另一端从卡槽21的另一端(卡槽的该另一端位于面10a和10b中的另一个)离开卡槽21。
需要说明的是，本公开实施例提供的厚度检测装置不仅可以用于检测背光源的厚度，也可以用于检测其它待检测件的厚度。
例如，卡槽组件20的该n个卡槽21的宽度相同以利用该n个卡槽对同一类型背光源进行厚度检测，也就是说，在任一卡槽21因磨损而不能使用的情况下，通过驱动组件30切换到其它卡槽21进行厚度检测即可，无需更换卡槽组件20。或者，在其它实施例中，例如，该卡槽组件20的n个卡槽21包括宽度不同的卡槽，并且每个宽度对应多个卡槽，以利用同一卡槽组件20对多种类型的背光源进行厚度检测，无需更换卡槽组件20。
该驱动组件30与卡槽组件20固定连接，该驱动组件30被配置为带动卡槽组件20移动，以切换卡槽组件20中当前与通槽11连通的卡槽21(例如，切换前通槽11与第一卡槽连通，切换后通槽11与第二卡槽连通，并且第一卡槽与第二卡槽为不同的卡槽)。需要说明的是，固定连接可以为可拆卸式的固定连接(拆开时不破坏连接件和被连接件)，例如螺纹连接、键连接或者卡接等；或者，固定连接也可以为不可拆卸式的固定连接(拆开时破坏连接件或被连接件)，例如焊接或者铆接等。
在本公开实施例中，若该厚度检测装置中某个卡槽的厚度检测次数较多，可以采用驱动组件30带动卡槽组件20移动，以切换卡槽组件20中当前与通槽11连通的卡槽21，使得卡槽组件20中未进行厚度检测的卡槽与通槽11连通。例如，假设当前与通槽11连通的卡槽为卡槽21a，若采用该卡槽21a进行厚度检测的检测次数较多，该卡槽21a可能会被磨损，通过驱动组件30带动卡槽组件20移动，使得未进行厚度检测的卡槽21b与通槽11连通，此时，可以采用该卡槽21b对待检测件进行厚度检测。
例如，卡槽组件20采用塑料等材料制作，以避免对待检测件造成较大的磨损。
为了提高自动化程度，除了在某个卡槽21因磨损而更换到其它卡槽21 时驱动组件30驱动卡槽组件20移动，例如，驱动组件30还被配置为：根据待检测件(例如背光源)的设计厚度(例如，该设计厚度可通过操作人员手动输入)，带动卡槽组件20移动，以切换卡槽组件20中当前与通槽11连通的卡槽21，并且在切换后与通槽11连通的卡槽21的宽度对应待检测件的设计厚度。卡槽的宽度对应待检测件的设计厚度是指卡槽的宽度是根据该待检测件的设计厚度确定的。例如，卡槽的宽度大于该待检测件的设计厚度以使该待检测件能进入该卡槽中，并且卡槽的宽度与该待检测件的设计厚度之差为该待检测件的厚度的最大允许误差。
综上所述，本公开实施例提供的厚度检测装置，包括基座，以及在该基座上设置的卡槽组件和驱动组件，该卡槽组件具有n个卡槽，n为大于1的整数，驱动组件与卡槽组件固定连接，该驱动组件被配置为带动卡槽组件移动，以切换卡槽组件中当前与通槽连通的卡槽。若采用当前与通槽连通的卡槽对待检测件进行厚度检测的检测次数较多，可以通过驱动组件带动卡槽组件移动，使得未进行厚度检测的卡槽与通槽连通，从而有效的提高了检测精度。进一步的，该厚度检测装置是通过驱动组件切换卡槽组件中当前与通槽连通的卡槽的，无需频繁的更换卡槽结构，提高了对待检测件厚度检测的效率。
例如，请参考图3，图3是本公开实施例提供的厚度检测装置中卡槽组件的结构示意图，该卡槽组件20可以包括轮形结构22，n个卡槽21均匀地分布在轮形结构22的边缘处，例如，当n＝8时，8个卡槽21均匀的分布在轮形结构22的边缘处。厚度检测装置中的驱动组件被配置为带动该卡槽组件20转动。
在本公开实施例中，驱动组件的种类可以不同，该驱动组件可以为自动的驱动组件，也可以为手动的驱动组件，因此，上述驱动组件带动卡槽组件转动有多种可实现方式。例如，当驱动组件为手动的驱动组件时，该驱动组件可以包括驱动扳手、驱动手柄或驱动手轮等，若需要对卡槽组件进行调节，操作人员可以手动转动该驱动组件，以使该驱动组件能够带动卡槽组件转动。当驱动组件为自动的驱动组件时，该驱动组件可以自动的对卡槽组件进行调节，以下内容以驱动组件自动对卡槽组件进行调节为例进行详细说明：
请参考图4，图4是本公开实施例提供的厚度检测装置中驱动组件的结 构示意图，该驱动组件30可以包括驱动电极32，例如驱动组件30包括齿轮组31与驱动电机32，该驱动电机32被配置为带动齿轮组31转动，该齿轮组31与卡槽组件固定连接。例如，卡槽组件上可以设置有键槽(例如，图3中的键槽23)以使卡槽组件20与驱动组件30的传动轴33之间实现键连接，齿轮组31上也可以设置有键槽(图4中未标注)，该齿轮组31可以与卡槽组件通过定位键(图4中未标注)固定连接。示例的，齿轮组31包括两个啮合的直齿轮，驱动电机32可以与齿轮组31中的一个直齿轮固定连接，该齿轮组31中的另一个直齿轮可以与卡槽组件固定连接。需要说明的是，图4是以齿轮组31包括两个啮合的直齿轮为例进行示意性说明的，在另一个可选的实现方式中，该齿轮组可以包括一个直齿轮、三个依次啮合的直齿轮或者更多个的依次啮合的直齿轮，本公开实施例对此不作限定。
例如，请参考图5，图5是本公开实施例提供的厚度检测装置的主视图，该厚度检测装置还可以包括限位组件40，该限位组件40设置在基座10上，该限位组件40的一端与n个卡槽21中的一个卡槽抵接，该限位组件40被配置为在驱动组件未工作时限制卡槽组件20移动。通常情况下，在厚度检测装置对待检测件(例如背光源)进行厚度检测时，通过限位组件40可以限制卡槽组件20移动，从而保证在对待检测件进行厚度检测的过程中，待检测件的边缘能够平稳的穿过卡槽，降低了待检测件的边缘对卡槽磨损的概率。该限位组件40所抵接的卡槽与通槽11所连通的卡槽不同，例如，假设当前与通槽11连通的卡槽为卡槽21c，限位组件40所抵接的卡槽为卡槽21d，若n个卡槽21均匀的分布在轮形结构22的边缘处，当n为偶数时，卡槽21c与卡槽21d可以为相对的两个卡槽。
示例的，限位组件40可以包括限位杆41和压缩弹簧(图5中未示出)，为了更清楚的看出限位组件40的结构，请参考图6，图6是图5示出的厚度检测装置的侧视图，该压缩弹簧42穿过限位杆41。例如，压缩弹簧42的靠近卡槽组件20的一端42a与限位杆41固定连接，压缩弹簧42的远离卡槽组件20的一端抵在底座10上。压缩弹簧42的两端的连接方式并不局限于图6所示实施例，例如，在其它实施例中，该压缩弹簧42的两端分别卡接在限位杆41的两侧(例如两端)。如图1、图5至图7所示，该限位杆41的一端设置有斜面结构41a，该斜面结构41a与n个卡槽21中的一个卡槽抵接。例 如，该斜面结构41a被配置为在卡槽组件20转动时，带动限位杆41向远离卡槽组件20的方向x移动，压缩弹簧42被配置为在卡槽组件20停止转动时，带动限位杆41抵接在与该一个卡槽相邻的卡槽中。例如，该斜面结构41a可以与卡槽21d抵接，若卡槽组件20在驱动组件30的带动下转动，在斜面结构41a与卡槽21d的侧面产生相互作用，使得限位杆41向远离卡槽组件20的方向x移动；通常情况下，在卡槽组件20停止转动时，与卡槽21d相邻的卡槽21e会运动到限位组件40附近，在压缩弹簧42的弹力作用下，限位杆41会抵接在该卡槽21e中。
在本公开实施例中，当卡槽组件中当前与通槽连通的卡槽进行厚度检测的检测次数较多时，对该卡槽进行切换，为了提高切换效率，可以在该厚度检测装置中设置计数器。示例的，请参考图4和图7，图7是本公开实施例提供的又一种厚度检测装置的结构示意图，该厚度检测装置92还可以包括计数器50，该计数器50被配置为统计当前与通槽21连通的卡槽(例如，可以为卡槽21a)进行厚度检测的检测次数，通常情况下，卡槽21a在对1个具有某设计厚度的待检测件的进行厚度检测后，计数器50可以统计出卡槽21a进行厚度检测的检测次数为1次；卡槽21a在对100个具有该设计厚度的待检测件(例如背光源)的进行厚度检测后，计数器50可以统计出卡槽21a进行厚度检测的检测次数为100次。
示例的，可以在基座10的凹槽(下文称为第一凹槽)12上设置传感组件，该传感组件可以为光信号传感器或压力传感器，该传感组件与计数器电连接，当通过厚度检测装置对待检测件(例如背光源)进行厚度检测时，传感组件能够感应到待检测件的边缘从厚度检测装置中的卡槽穿过，传感组件可以在感应到待检测件的边缘从厚度检测装置中的卡槽穿过后生成感应信号，该传感组件可以将生成的感应信号传递给计时器，以使计数器能够基于该感应信号完成对一次厚度检测的计数。
例如，如图4所示，基座10还设置有电路板90，其与驱动组件30、计数器50、传感组件等电子元件电连接，以控制这些电子元件的工作状态。
该计数器50可以与驱动组件30电连接，例如，该计数器50可以与驱动组件中的驱动电机电连接，该驱动组件30被配置为在计数器50统计到检测次数达到预设次数时，带动卡槽组件20移动，以切换卡槽组件20中当前与 通槽连通的卡槽(例如，可以为卡槽21a)。例如，该预设次数(例如，预设次数可以根据卡槽的材质确定)可以为4000次，在卡槽21a的检测次数达到4000次时，可以认为该卡槽21a可能被损坏，因此需要通过驱动组件带动卡槽组件20移动，来对该卡槽21a进行切换，使得后续可以采用其他未进行厚度检测的卡槽进行待检测件的厚度检测。需要说明的是，在通过驱动组件完成对卡槽的切换后，计数器50可以对其所记录的检测次数进行归零处理，以使该计数器50能够重新对新的卡槽的检测次数进行统计。
在本公开实施例中，计数器50在统计到检测次数达到预设次数时，可以向驱动组件中的驱动电机发送驱动指令，在驱动电机接收到驱动指令后，该驱动电机可以带动齿轮组转动，以带动卡槽组件20转动，直至与卡槽21a相邻的卡槽21b和通槽11连通为止。在一种例如实现方式中，若n个卡槽21均匀的分布在轮形结构22的边缘处，驱动电机的驱动时间通常是预先设置的，在每次驱动电机工作时，该驱动电机均能够带动卡槽组件20转动固定的角度，该固定的角度为两个相邻的卡槽的中心线所形成的夹角的角度。
例如，如图7所示，该厚度检测装置还可以包括报警组件60，该报警组件60分别与驱动组件和计数器50电连接，例如，该报警组件60可以与驱动组件中的驱动电机电连接。该报警组件60被配置为在检测到驱动组件带动卡槽组件20移动n-1次后，当计数器50统计到检测次数达到预设次数时，发出用于指示卡槽组件20中的所有卡槽的检测次数均达到预设次数的报警信号。例如，假设n＝8，若报警组件60在检测到驱动组件带动卡槽组件20移动7次后，当计数器50又统计到卡槽进行厚度检测的检测次数达到预设次数时，该卡槽组件20中的所有的卡槽可能均受到了磨损，如果进行采用该卡槽组件20进行厚度检测，则检测精度会降低，因此，该报警组件60能够发出用于指示卡槽组件20中的所有卡槽的检测次数均达到预设次数的报警信号，以提示操作人员对厚度检测装置中的卡槽组件进行更换。例如，该报警组件60可以为光电报警器或电声警报器等。
例如，如图1、图5至图7任一所示，该厚度检测装置92还可以包括显示器5，显示器5被配置为显示计数器50统计到的检测次数。
例如，请参考图8所示，图8是本公开实施例提供的基座10的结构示意图，该基座10上还设置有用于安装卡槽组件的第一凹槽12，即卡槽组件所 在的第一安装面10a设置有第一凹槽12。例如，基座10还设置有用于安装限位组件的第二凹槽13。例如，如图4所示，该第二凹槽13在基座10的面10d处形成有开口14，限位杆41穿过该开口14。例如，第二凹槽13也设置于第一安装面10a。
例如，如图1、图5或图7所示，该厚度检测装置92还可以包括盖板70，该盖板70安装在第二凹槽13处，用于防止第二凹槽中的限位组件40脱落。例如，盖板70为透明盖板，以便于观察限位组件40的状态。
例如，如图4或图6所示，驱动组件30设置在基座10中背离第一凹槽12与第二凹槽13的一面10b(在这种情况下，该面10b为第二安装面)上，即驱动组件30与卡槽组件20分别安装在基座10的两个设置面(即第一安装面10a和第二安装面10b)上。
例如，如图1、图5至图7任一所示，该厚度检测装置92还可以包括箱体80，该箱体80被配置为扣置在基座10上，以使驱动组件30位于箱体80内。通过该箱体80可以防止驱动组件30从基座10上脱落。
综上所述，本公开实施例提供的厚度检测装置，包括基座，以及在该基座上设置的卡槽组件和驱动组件，该卡槽组件具有n个卡槽，n为大于1的整数，驱动组件与卡槽组件固定连接，该驱动组件被配置为带动卡槽组件移动，以切换卡槽组件中当前与通槽连通的卡槽。若采用当前与通槽连通的卡槽对待检测件进行厚度检测的次数较多，可以通过驱动组件带动卡槽组件移动，使得未进行厚度检测的卡槽与通槽连通，从而有效的提高了检测精度。进一步的，该厚度检测装置是通过驱动组件切换卡槽组件中当前与通槽连通的卡槽的，相对于相关技术无需频繁的更换卡结构，提高了对待检测件厚度检测的效率。
本公开实施例提供了一种测试系统，请参考图9，图9是本公开实施例提供的一种测试系统的结构示意图，该测试系统可以包括承载基台91和厚度检测装置92，该厚度检测装置92可以为图1、图5至图7中任一示出的厚度检测装置。该承载基台91用于承载待检测的待检测件(例如背光源)93。例如，该测试系统还可以包括：移动组件94，该移动组件94用于带动承载基台92移动，以使该承载基台91所承载的待检测件93的边缘穿过厚度检测装置92中的卡槽21。例如，该移动组件94用于带动承载基台92转动，以使 待检测件93的多个边缘逐个穿过卡槽21。
本公开实施例还提供一种利用以上任一项实施例提供的厚度检测装置进行厚度检测的方法，该方法包括以下步骤S1至步骤S3。
步骤S1：根据待检测件的设计厚度选择卡槽组件的卡槽。如上所述，卡槽的宽度是根据该待检测件的设计厚度确定的，因此在检测厚度的过程中根据设计厚度选择合适的卡槽进行检测。例如，待检测件为背光源或者其它需要进行厚度检测的装置。
步骤S2：将所选择的卡槽与通槽连通。参考以上关于厚度检测装置的实施例，通过驱动组件带动卡槽组件移动来使卡槽与通槽连通并且实现卡槽之间的切换。
步骤S3：通过将待检测件移入所选择的卡槽中来判断待测试件的最大厚度是否小于所选择的卡槽的槽宽，其中，若待检测件能够被移入卡槽中，则待检测件的厚度符合要求。例如，通过使待检测件的一个或多个边缘穿过卡槽来检测待检测件的厚度是否符合要求。
本公开实施例还提供一种卡槽装置，如图10所示，该卡槽装置包括基座100、卡槽组件20和驱动组件30。卡槽组件20设置在基座100上，卡槽组件20具有n个卡槽21，n为大于1的整数。驱动组件30设置在基座100上，驱动组件30与卡槽组件20固定连接，驱动组件30被配置为带动卡槽组件20移动，以切换卡槽组件20中的卡槽21。
例如，基座100设置有贯穿其的通槽，例如该通槽沿基座100的厚度方向延伸，在这种情况下，该基座100与以上实施例中的基座10的设置方式相同。在其它实施例中，基座100也可以未设置通槽，在这种情况下，例如，通过使正在使用的卡槽21在基座100上的正投影位于基座100所在区域之外即可使待检测件穿过卡槽。
例如，该卡槽装置中的驱动组件30和卡槽组件20可以采用以上关于厚度检测装置的实施例中的相应部件的设置方式；例如，该卡槽装置还可以包括厚度检测装置的实施例中提及的限位组件40、计数器50、报警组件60、盖板70、箱体80、电路板90和显示器5等结构中的至少一个或多个，重复之处不再赘述。
本公开实施例提供的卡槽装置可以用于厚度检测或者其它需要使用卡槽 的情形。
综上所述，在本公开实施例提供厚度检测装置、厚度检测方法、检测系统和卡槽装置中，卡槽组件具有多个宽度相同的卡槽，并且驱动组件被配置为带动卡槽组件移动以切换卡槽组件中当前与通槽连通的卡槽；若采用当前与通槽连通的卡槽对待检测件进行厚度检测的检测次数较多，可以通过驱动组件带动卡槽组件移动，使得未进行厚度检测的卡槽与通槽连通，从而有效地提高了检测精度。进一步的，该厚度检测装置是通过驱动组件切换卡槽组件中当前与通槽连通的卡槽的，无需频繁地更换卡槽结构，提高了对待检测件厚度检测的效率。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
