Description

一种LED显示屏 技术领域
本发明涉及LED显示屏技术领域，尤其是一种LED显示屏。
背景技术
在LED显示屏行业内，LED显示屏的显示模组拼接的平整度和像素间距误差对显示的效果有直接影响，但是目前只能通过加工精度来保证其拼接的平整度和像素间距。为了避免LED显示屏因像素间距差异而带来的亮线、暗线被人眼感知，需要控制像素间距之间的误差在5％以内，当像素间距小于5％时，人眼就无法感知。而在LED显示屏的显示模组之间的像素间距为0.7mm时，其5％的误差则为0.035mm，就需要将相邻模组之间的像素间距的差控制在0.035mm。
另外，由于显示屏上的LED尺寸一定会小于显示屏的间距，所以0.7mm的间距的显示屏只能用0.5mm的LED，这种小的LED特别容易因碰撞而损坏或脱落，同时小间距的显示屏由于空间小，维修、维护很困难。
如中国发明专利：CN202121616219.6，一种LED显示模组及显示屏，显示屏箱体上设置有固定支架，显示屏箱体上设置有滑动安装槽，所述滑动安装槽上设置有活动支架，固定支架上固定设置有电源母头，活动支架上固定设置有电源公头，箱体上还固定设置有盖板，所述盖板上可转动地设置有锁舌，锁舌的自由端设置有驱动柱，活动支架上开设有驱动槽，驱动柱的一端伸入到所述驱动槽内，显示屏箱体与显示单元之间设置有调节零件，显示屏箱体上开设有用于调节所述调节零件的箱体调节通孔。
其方案难以实现对显示模组的位置进行调节以确保像素间距和平整度都在合理范围内。
发明内容
本发明为了解决上述技术不足而提供一种LED显示屏，其能实现对LED显示屏的显示模组的像素间距、平整度进行调节。
本发明公开了一种LED显示屏，包括若干个显示屏箱体，相邻显示屏箱体之间通过连接件固定，在每个显示屏箱体内阵列有若干显示模组，每个显示模组通过至少六个调整装置设置在显示屏箱体内，每个显示模组上的调整装置配合用于实现显示模组在XYZ方向的移动及XYZ方向的转动。
上述显示屏箱体通过连接件固定后，显示屏箱体之间的间隙比较小，所以在需要维修、维护过程中，可以通过调整装置，带动显示屏箱体内的显示模组移动，从而将显示屏箱体之间的连接件暴露，从而将显示屏箱体进行拆卸。同时显示屏箱体内的显示模组可以通过调整装置实现相邻显示模组之间的像素间隙、平整度进行调整，以达到规定误差范围内。同时通过调整装置对显示模组的调节，可以实现不拆卸显示模组即可完成连线操作。
所述调整装置具有伸缩功能，且每个调整装置的伸缩方向与显示模组上调整装置安装的平面之间呈锐角。由于调整装置仅实现伸缩功能，所以需要将调整装置的安装角度与显示模组之间形成锐角，所以可以实现对显示模组进行六自由度的调节。
所述调整装置的结构为：包括安装座、电动机、调整螺套，所述电动机设置在安装座上，所述调节螺套转动连接在安装座上，电动机与调节螺套之间传动连接，在调节螺套上设置有内螺纹和外螺纹，在调节螺套上设置有螺杆和螺母，所述螺杆与调节螺套上的内螺纹连接，所述螺母与调节螺套上的外螺纹连接，所述螺杆、螺母与安装座之间均沿调节螺套的轴向滑动连接，在螺杆、螺母的端部设置有连接球，其中一个连接球用于与显 示模组之间万向连接，另一个连接球用于与箱体之间万向连接；在螺杆、螺母与所述调节螺套相配合的端部沿径向开设有一条或多条贯通的槽。
上述方案中，调节螺套转动连接在安装座上，并与电动机之间传动连接，通过电动机带动其转动。在调节螺套转动过程中可以实现螺杆和螺母上的连接球之间的间距会发生变化，从而实现对连接球所连接的部件即显示模组与箱体之间进行位置调节。在螺杆、螺母上与调节螺套相配合的一端开设有槽，该槽沿径向设置。该槽将螺杆的端部或者螺母的端部切分为若干部分，且相邻部分之间存在间隙，所以相邻部分之间具有一定的变形能力，当所述螺杆与调节螺套的内螺纹配合时，螺杆上设置有槽的部分可以处于被细微压缩形变状态，从而使得其与调节螺套之间具有张紧力，同样螺母与调节螺套的外螺纹配合时，螺母上设置有槽的部分可以处于被撑开变形状态，所以螺母与调节螺套之间也具有张紧力。通过上述张紧力能消除螺母与调节螺套之间及螺杆与调节螺套之间的间隙，保证电动机的传动位置唯一，从而对两个连接球之间的位置控制更加精确，精度一般可以达到0.01mm甚至更高。
在调节螺套的其中一端设置有从动齿轮，所述电动机的输出轴上设置有主动齿轮，所述主动齿轮与从动齿轮相互配合连接，在安装座上设置有压盖，所述压盖用于限制调节螺套在安装座上的轴向位置。利用压板限制调节螺套在安装座上的轴向位置，以确保轴向位置稳定，不会在传动过程中因调节螺杆发生细微轴向位移而影响调节精度。
所述螺杆与所述压盖之间滑动连接，所述螺杆穿过压盖，在压盖上设置有第二凸起，在所述螺杆上沿轴向设置有第二滑槽，所述第二凸起与第二滑槽配合连接；在未与调节螺套相配合的螺杆端部设置有第二弧形凹腔，所述连接球设置在第二弧形凹腔内，在第二弧形凹腔处的螺杆上设置有限位螺母，所述限位螺母将连接球限制在螺杆端部的第二弧形凹腔内，在该 连接球上设置有连接部，所述连接部延伸至限位螺母外部，连接部与显示模组连接。由于压盖厚度较小，所以将第二凸起设置在压盖上，将第二滑槽设置在螺杆上，两者在相对运动过程中，第二凸起在第二滑槽内滑动，所以两者之间仅可以实现轴向位移。在螺杆端部设置第二弧形凹腔，将连接球设置在第二弧形凹腔内，连接部用于连接调整装置所调节的部件，如显示模组等。连接球在第二弧形腔体内可以转动，所以在调整装置伸缩过程中可以改变连接部与螺杆之间的角度。
在螺母的外表面沿轴向设置有第一凸起，在安装座上设置有与第一凸起相配合的第一滑槽；在未与调节螺套相配合的螺母的端部设置有第一弧形凹腔，在螺母的第一弧形凹腔处设置有盖板，所述连接球设置在盖板内的第一弧形凹腔内，在连接球上设置连接轴，在连接轴上设置有连接座，所述连接座固定在箱体上。通过螺母外表面的第一凸起与安装座上的第一滑槽配合，可以限制螺母发生转动，实现其仅沿调节螺套的轴向移动。通过连接座实现对箱体进行固定，通过连接球的设计，可以在调节过程中，能实现螺母、调节螺套的轴向与连接座之间的角度可以自由调节。
还包括控制器，在显示模组上的拼接边缘上设置有信号发射器和/或信号接收器，显示模组拼接呈屏幕后，其中一个显示模组上的信号发射器与相邻显示模组上的信号接收器对应，所述对应的信号发射器与信号接收器之间检测两者之间的距离。通过相邻的显示模组之间的信号发射器、信号接收器进行间距测量及高低平整度测量，并将测量数据传输至控制器。由于信号发射器、信号接收器与显示模组之间存在间距，所以控制器将测量的数据减去信号发射器、信号接收器与显示模组边缘之间的间距，得到相邻显示模组之间的间距，另外，平整度也可以通过测量计算得到。而控制器根据计算得到的像素间距及平整度，控制调整装置，对显示模组进行调节，信号发射器、信号接收器、控制器和调整装置之间形成闭环控制， 最终实现相邻显示模组之间的像素间距、平整度均处于合理的误差范围内。上述显示模组在装配过程中可以实现自主测量及调整，无需借助其他辅助设备，调节精度高。
在每个显示模组的拼接边缘设置的信号发射器和信号接收器的数量为2个以上，且显示模组的同一拼接边缘上的信号发射器和/或信号接收器间隔设置。由于现实模组本体一般为矩形结构，利用在显示模组的拼接边缘设置至少两个信号接收器和/或信号发射器，即可以在相邻两个显示模组相对的拼接边缘之间检测两个位置的间距，从而可以保证显示模组两个边缘之间任意位置的间距相同，能极大提升对显示模组之间间距测量的精度，其测量平整度也是同理，也可以提升平整度的测量精度。
所述信号发射器所发射的信号为电磁波，所述信号接收器用于将电磁波信号转换为可以辨识的电信号。所述信号发射器可以包括电磁铁及其阵列，或者为光学(激光，可见光，紫外光等)、声音、微波等信号发射源装置。所述信号接收器为霍尔传感器(电感，电容，阻抗)或者为磁电转换装置，光(激光，可见光，紫外光等)电转换装置、声电转换装置等，将发射源的信号转变为可以辨识的电信号。
所述显示屏箱体，包括底壁和侧壁，所述底壁和侧壁形成一个矩形结构的内凹腔体，在每个侧壁外表面的两端均设置有向外凸起的连接柱，所述连接柱上设置有连接孔，在显示屏箱体拼接时，相邻侧壁上的连接柱交错对接，相邻侧壁上的连接柱之间通过连接件固定连接。上述方案，通过在侧壁外表面的连接柱设置，能实现对显示屏箱体之间相互连接，而且相邻显示屏箱体之间的连接间隙可以通过连接柱凸出与侧壁的部分进行控制，当然，在也可以在设置有连接柱处的侧壁局部内凹，以保证相邻显示屏箱体之间拼接后的间隙可控在需要范围内。
每个侧壁的端部设置有至少两个间隔设置的连接柱，连接柱上设置的 连接孔的轴向平行。在每个侧壁的端部均设置两个连接柱，所以拼接后其稳定性更高。
所述连接柱上的连接孔为第一连接孔，在连接件上设置有第二连接孔，所述第一连接孔和第二连接孔一一对应，在第一连接孔和第二连接孔内部均设置环形凸起，在第一连接孔和第二连接孔内部的环形凸起之间设置有连接螺套，在第一连接孔和第二连接孔内均设置有一个螺栓，所述螺栓分别与连接螺套的两端锁紧连接。该结构的设计，相邻两个显示屏箱体通过连接件进行连接时，相对应的第一连接孔与第二连接孔内分别设置有螺栓，且其中一个螺栓位于正面，另一个螺栓位于背面。在后续维护过程中，无论是前维护还是后维护，仅需要将其螺栓拆卸就可实现相邻显示屏箱体之间的分离。
本发明所得到的一种LED显示屏，能提升LED显示屏的拼接精度，同时可以降低显示屏箱体及显示模组的机械加工精度要求，对显示模组上的LED具有很好的保护作用，同时不拆卸显示模组即可进行连线操作，维护简单方便。

具体实施方式
为更进一步阐述本发明为实现预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本发明的具体实施方式、结构、特征及其功效，详细说明如后。
实施例1：
如图1-图6所示，本发明公开了一种显示屏箱体，包括底壁25和侧壁26，所述底壁25和侧壁26形成一个矩形结构的内凹腔体，在每个侧壁26外表面的两端均设置有向外凸起的连接柱27，所述连接柱27上设置有连接孔，在显示屏箱体22拼接时，相邻侧壁26上的连接柱27交错对接，相邻侧壁26上的连接柱27之间通过连接件28固定连接。上述方案，通过在侧壁26外表面的连接柱27设置，能实现对显示屏箱体22之间相互连接，而且相邻显示屏箱体22之间的连接间隙可以通过连接柱27凸出与侧壁26的部分进行控制，当然，在也可以在设置有连接柱27处的侧壁26局部内凹，以保证相邻显示屏箱体22之间拼接后的间隙可控在需要范围内。
每个侧壁26的端部设置有至少两个间隔设置的连接柱27，连接柱27上设置的连接孔的轴向平行。在每个侧壁26的端部均设置两个连接柱27，所以拼接后其稳定性更高。
所述连接柱27上的连接孔为第一连接孔29，在连接件28上设置有第二连接孔34，所述第一连接孔29和第二连接孔34一一对应，在第一连接孔29和第二连接孔34内部均设置环形凸起31，在第一连接孔29和第二连接孔34内部的环形凸起31之间设置有连接螺套30，在第一连接孔29和第二连接孔34内均设置有一个螺栓32，所述螺栓32分别与连接螺套30的两端锁紧连接。该结构的设计，相邻两个显示屏箱体22通过连接件28进行连接时，相对应的第一连接孔29与第二连接孔34内分别设置有螺栓32，且其中一个螺栓32位于正面，另一个螺栓32位于背面。在后续维护过程中，无论是前维护还是后维护，仅需要将其螺栓32拆卸就可实现相邻显示屏箱体22之间的分离。
实施例2：
如图2所示，本发明公开了一种LED显示屏，包括若干个显示屏箱体22，相邻显示屏箱体22之间通过连接件28固定，在每个显示屏箱体22内阵列有若干显示模组20，每个显示模组20通过至少六个调整装置设置在显示屏箱体22内，每个显示模组20上的调整装置配合用于实现显示模组20在XYZ方向的移动及XYZ方向的转动。本实施例中，调整装置的数量可以为6个，当然也可以为更多，如7个、8个等。本实施例的显示屏箱体采用实施例1中所述的结构。
上述显示屏箱体22通过连接件28固定后，显示屏箱体22之间的间隙比较小，所以在需要维修、维护过程中，可以通过调整装置，带动显示屏箱体22内的显示模组20移动，从而将显示屏箱体22之间的连接件28暴露，从而将显示屏箱体22进行拆卸。同时显示屏箱体22内的显示模组 20可以通过调整装置实现相邻显示模组20之间的像素间隙、平整度进行调整，以达到规定误差范围内。同时通过调整装置对显示模组20的调节，可以实现不拆卸显示模组20即可完成连线操作。
所述调整装置21具有伸缩功能，且每个调整装置21的伸缩方向与显示模组20上调整装置21安装的平面之间呈锐角。由于调整装置21仅实现伸缩功能，所以需要将调整装置21的安装角度与显示模组20之间形成锐角，所以可以实现对显示模组20进行六自由度的调节。
如图9-19所示，所述调整装置21的结构为：包括安装座1、电动机3、调整螺套，所述电动机3设置在安装座1上，所述调节螺套13转动连接在安装座1上，电动机3与调节螺套13之间传动连接，在调节螺套13上设置有内螺纹和外螺纹，在调节螺套13上设置有螺杆4和螺母5，所述螺杆4对应与调节螺套13上的内螺纹连接，所述螺母5对应与调节螺套13上的外螺纹连接，所述螺杆4、螺母5与安装座1之间均沿调节螺套13的轴向滑动连接，在螺杆4、螺母5的端部设置有连接球8，其中一个连接球8用于与显示模组20之间万向连接，另一个连接球8用于与箱体之间万向连接；在螺杆4、螺母5与所述调节螺套13相配合的端部沿径向开设有两条贯通的槽16。
上述方案中，调节螺套13转动连接在安装座1上，并与电动机3之间传动连接，通过电动机3带动其转动。在调节螺套13转动过程中可以实现螺杆4和螺母5上的连接球8之间的间距会发生变化，从而实现对连接球8所连接的部件进行位置调节。在LED显示屏中，所述其中一个连接球8用于连接显示模组20，另一个连接球8用于连接在箱体上，从而调节显示模组20相对于箱体的相对位置。在螺杆4、螺母5上与调节螺套13相配合的一端开设有槽16，该槽16沿径向设置。该槽16将螺杆4的端部和螺母5的端部分别切分为若干部分，且相邻部分之间存在间隙， 所以相邻部分之间具有一定的变形能力，当所述螺杆4与调节螺套13的内螺纹配合时，螺杆4上设置有槽16的部分可以处于被细微压缩形变状态，从而使得其与调节螺套13之间具有张紧力，同样螺母5与调节螺套13的外螺纹配合时，螺母5上设置有槽16的部分可以处于被撑开变形状态，所以螺母5与调节螺套13之间也具有张紧力。通过上述张紧力能消除螺母5与调节螺套13之间及螺杆4与调节螺套13之间的间隙，保证电动机3的传动位置唯一，从而对两个连接球8之间的位置控制更加精确，精度一般可以达到0.01mm甚至更高。
本实施例的方案采用两级螺纹传动，在电动机3对调节螺套13进行转动时，螺杆4和螺母5在调节螺套13上的运动方向相反。两级螺纹传动，能有效缩小整个电动伸缩调整装置21的体积，并采用螺纹设计，具有良好的自锁功能，在任何位置，只需要停止动力输入既可以确保其保持位置不变。
在调节螺套13的其中一端设置有从动齿轮14，所述电动机3的输出轴上设置有主动齿轮15，所述主动齿轮15与从动齿轮14相互配合连接，在安装座1上设置有压盖2，所述压盖2用于限制调节螺套13在安装座1上的轴向位置。利用压板限制调节螺套13在安装座1上的轴向位置，以确保轴向位置稳定，不会在传动过程中因调节螺杆4发生细微轴向位移而影响调节精度。
所述螺杆4与所述压盖2之间滑动连接，所述螺杆4穿过压盖2，在压盖2上设置有第二凸起11，在所述螺杆4上沿轴向设置有第二滑槽10，所述第二凸起11与第二滑槽10配合连接。由于压盖2厚度较小，所以将第二凸起11设置在压盖2上，将第二滑槽10设置在螺杆4上，两者在相对运动过程中，第二凸起11在第二滑槽10内滑动，所以两者之间仅可以实现轴向位移。当然，设置有螺杆4的情况下，所述连接球8就设置在螺 杆4的端部。
在未与调节螺套13相配合的螺杆4端部设置有第二弧形凹腔19，所述连接球8设置在第二弧形凹腔19内，在第二弧形凹腔19处的螺杆4上设置有限位螺母7，所述限位螺母7将连接球8限制在螺杆4端部的第二弧形凹腔19内，在该连接球8上设置有连接部9，所述连接部9延伸至限位螺母7外部，连接部9与显示模组20连接。在螺杆4端部设置第二弧形凹腔19，将连接球8设置在第二弧形凹腔19内，连接部9用于连接调整装置21所调节的部件，如显示模组20。连接球8在第二弧形腔体内可以转动，所以在调整装置21伸缩过程中可以改变连接部9与螺杆4之间的角度。
在螺母5的外表面沿轴向设置有第一凸起12，在安装座1上设置有与第一凸起12相配合的第一滑槽16。通过螺母5外表面的第一凸起12与安装座1上的第一滑槽16配合，可以限制螺母5发生转动，实现其仅沿调节螺套13的轴向移动。
在未与调节螺套13相配合的螺母5的端部设置有第一弧形凹腔，在螺母5的第一弧形凹腔处设置有盖板18，所述连接球8设置在盖板18内的第一弧形凹腔内，在连接球8上设置连接轴17，在连接轴17上设置有连接座6，所述连接座6固定在箱体上。通过连接座6实现对箱体进行固定，通过连接球8的设计，可以在调节过程中，能实现螺母5、调节螺套13的轴向与连接座6之间的角度可以自由调节。
所述电动机3可以为减速电机，或者电动机3内集成有减速器。
如图7、图8所示，还包括控制器，在显示模组20上的拼接边缘上设置有信号发射器23和信号接收器24，显示模组20拼接呈屏幕后，其中一个显示模组20上的信号发射器23与相邻显示模组20上的信号接收器24对应，所述对应的信号发射器23与信号接收器24之间检测两者之 间的距离，通过相邻的显示模组20之间的信号发射器23、信号接收器24进行间距测量及高低平整度测量，并将测量数据传输至控制器。由于信号发射器23、信号接收器24与显示模组20之间存在间距，所以控制器将测量的数据减去信号发射器23、信号接收器24与显示模组20边缘之间的间距，得到相邻显示模组之间的间距，另外，平整度也可以通过测量计算得到。而控制器根据计算得到的像素间距及平整度，控制调整装置，对显示模组20进行调节，信号发射器23、信号接收器24、控制器和调整装置21之间形成闭环控制，最终实现相邻显示模组20之间的像素间距、平整度均处于合理的误差范围内。上述显示模组在装配过程中可以实现自主测量及调整，无需借助其他辅助设备，调节精度高。
每个显示模组20上设置有信号发射器23和信号接收器24。当然可以根据实际需求，在某一个显示模组20上全部设置信号发射器23，在其相邻的显示模组20上设置信号接收器24，仅需要实现在相邻显示模组20的相对的拼接边缘上设置信号发射器23与信号接收器24即可。
在显示模组20的每条拼接边缘设置有一个信号发射器23和一个信号接收器24，且信号发射器23和信号接收器24分别设置在拼接边缘的两端，且信号接收器24和信号发射器23在显示模组20上沿顺时针或逆时针方向一对一间隔交替。
