在工业自动化领域中，直线电机的使用非常广泛。现已有的直线电机中，由于走线需要，直线电机的密封通常采用半封闭设置，但是如此设置，通常会使得直线电机在使用过程中受到外界环境的干扰，影响半封闭的直线电机的使用寿命。
鉴于此，本发明提供一种直线电机，其中，图1至图6为本发明提供的直线电机的一实施例的结构示意图。
请参阅图1及图3，所述直线电机100包括底座1、定子组件2、动子组件3、滑动件4及密封带5，所述底座1具有一安装腔a，所述底座1具有沿第一方向延伸的第一侧，所述底座1的第一侧开设有沿所述第一方向延伸且连通所述安装腔a的侧开口，所述定子组件2，设于所述安装腔a内，所述动子组件3设于所述安装腔a内，且沿所述安装腔a的第一方向滑动安装于所述底座1，所述滑动件4沿着所述第一方向滑动安装于所述底座1的侧开口，且连接于所述动子组件3，以被所述动子组件3带动滑动，因为所述密封带5的中间段与所述滑动件4滑动连接，所述滑动件4，且所述密封带5的两端固定安装于所述底座1，使得所述密封带5盖合所述侧开口，实现了所述直线电机100的全封闭，避免直线电机100因为是半封闭导致其在使用过程中受到外界环境的干扰，从而影响直线电机100的使用寿命。
需要说明的是，不限于所述第一侧开口，具体地，在本实施例中，所述底座1的两端还分别设置有一端开口，所述端开口通过对应设置的端盖(未图示)进行封闭，且所述直线电机100还包括两个压块(未图示)，两个所述压块用于将所述密封带5的两端固定于所述底座1，以使所述密封带5、所述滑动件4、所述压块及两个所述端盖共同作用，实现所述直线电机100的封闭。
实现所述密封带5的中间段与所述滑动件4滑动连接的形式有多种，本申请对此不作限定，例如，一种方式中，所述滑动件4内部贯设有沿所述第一方向延伸的过道，所述密封带的一端穿过所述过道，以实现所述密封带5的中间段与所述滑动件4滑动连接，如此设置，结构简单。另一种方式中，所述滑动件4在所述第一方向上的两端分别贯设有一过孔41，所述密封带5的两端自对应所述过孔41穿过，以实现所述密封带5的中间段与所述滑动件4滑动连接，为了使得所述密封带5与所述底座1更贴合，在本实施例中，所述密封带5的两 端均朝向所述底座1分别穿过相对应的两个所述过孔41，以固定安装于所述底座1，所述密封带5通过所述滑动件4朝向所述底座1的表面抵压，所述密封带5与所述底座1更贴接，使得封闭效果更好。
考虑到直线电机100线路的布置，所述滑动件4的一侧部设有设有一安装孔42，因为所述安装孔42与所述安装腔a相连通，使得设置于所述动子组件3的电连接线伸出所述安装孔42以连接外部设备，提高了所述直线电机100的封闭效果。
考虑到所述滑动件4在相对所述密封带5运动时存在磨损，所述滑动件4包括滑台43和摩擦块44，所述滑台43滑动安装于所述底座1且与所述动子组件3固定连接，所述摩擦块44夹设于所述滑台43与所述密封带5之间，通过在所述滑台43和所述密封带5之间设置摩擦块44，避免了所述滑台43的磨损，且当所述摩擦块44磨损时只需更换新的摩擦块44，节约成本，同时，所述摩擦块44的摩擦系数较小，也避免所述滑台43相对所述密封带5滑动时，受到的阻力较大，影响所述直线电机100的使用。
需要说明的是，所述摩擦块44的材质为耐磨尼龙、不锈钢等，在本申请中，摩擦块44的材质为耐磨尼龙，在其他实施例中可以根据需要进行选择。
参照图3和图4，所述过孔41设于所述摩擦块44，所述摩擦块44包括位于两个所述过孔41之间的摩擦块中部440、以及位于两个所述过孔41远离所述摩擦块中部440一侧的两个摩擦块端部441，所述摩擦块中部440具有与所述密封带5贴接的中部摩擦面，所述摩擦块端部441具有与所述密封带5贴接的端部摩擦面，其中，所述中部摩擦面在所述第一方向上的两端均呈圆弧状设置，如此设置，通过圆弧过渡，避免所述摩擦块中部440的两端呈棱角设置，导致所述密封带5磨损。
为了使得所述密封带5与所述底座1更贴合，所述端部摩擦面在远离所述过孔41的方向上呈逐渐靠近所述密封带5方向倾斜设置，以与所述密封带5相抵，如此设置，通过倾斜设置的所述端部摩擦面抵压所述密封带5，使得所述密封带5更贴接所述底座1，使得封闭效果更好。
参照图4，所述摩擦块44两侧部均设置有一缺口442，所述滑台42的两侧具有延伸至所述缺口442且与所述缺口442配合的配合部，通过将所述配合部与所述缺口442配合，实现了所述摩擦块44与所述滑台43的定位安装，结构简 单，且便于所述摩擦块44与所述滑台43的分离，当所述摩擦块44磨损时，更换方便。
需要说明的是，实现所述摩擦块44与所述滑台43定位安装的方式用多种，例如，所述摩擦块44与所述滑台43对应设置有定位孔和定位槽，通过所述定位孔与所述定位槽的配合安装实现所述摩擦块44与所述滑台43的定位配合等，本申请对此不作限定。
为了将所述摩擦块44安装于所述滑台43，参照图1、图5和图6，所述滑台43朝向所述摩擦块44的表面形成有一安装槽431，所述安装槽431沿所述第一方向延伸设置，通过将所述摩擦块44安装于所述安装槽431，实现了所述摩擦块44的安装。
为了实现所述滑台43沿所述第一方向滑动安装于所述底座1，所述滑台43与所述底座1的两个第一侧壁通过滑动配合结构滑动安装，所述滑动配合结构包括滑槽b和与所述滑槽b相适配的滑动凸起c，所述滑槽b和所述滑动凸起c中，其中一者设于所述滑台43，另一者设于所述底座1的第一侧壁，如此设置，保证了所述滑台43沿所述第一方向滑动安装于所述底座1，操作简单。
为了使得所述直线电机100更美观，参照图1和图2所述直线电机100还包括盖板6，所述盖板6盖设于所述密封带5背对所述底座1的一侧且与所述滑台43固定连接，如此设置，使得所述直线电机100更美观，且避免灰尘进入所述密封带5与所述摩擦块44之间的缝隙，影响所述滑台43的滑动。
为了将所述盖板6固定安装于所述滑台43，所述滑台43朝向所述摩擦块44的表面凸设有两组安装凸台432，两组所述安装凸台432分别位于所述安装槽431的两侧，所述盖板6对应两组所述安装凸台432设置有两组装配孔61，将所述安装凸台432安装于所述安装配孔61内，实现了所述盖板6与所述滑台43的定位安装。
考虑到所述盖板6相对所述密封带5运动时存在磨损，所述滑动件4还包括沿所述第一方向延伸设置的摩擦片45，所述摩擦片45夹设于所述密封带5与所述盖板6之间，通过在所述盖板6和所述密封带5之间设置所述摩擦片45，避免了所述盖板6的磨损，且当所述摩擦片45磨损时只需更换新的摩擦块44，节约成本，同时，所述摩擦片45的摩擦系数较小，也避免所述盖板6相对所述密封带5滑动时，受到的阻力较大，影响所述直线电机100的使用。
需要说明的是，所述摩擦片45的材质可以为不锈钢也可以为耐磨尼龙，具体地在本申请中，所述摩擦片45选择为不锈钢材质，在其他实施例中，可以根据需要进行选择。
参照图1和图3，任一组所述安装凸台432均包括两个沿所述第一方向间隔设置的安装凸台432，两个所述安装凸台432间形成一限位槽d，所述摩擦片45的两侧均延伸出一限位臂451，两个所述限位臂451分别对应安装于两个所述限位槽d，如此设置，实现了所述摩擦片45的定位安装，且避免所述摩擦片45相对所述滑台43滑动。
为了使得所述密封带5更贴接所述底座1，所述摩擦片45的两端均延伸出抵接臂452，所述抵接臂452与所述密封带5相抵，通过所述抵接臂452的抵接作用，使得所述密封带5与所述摩擦块44段远离所述底座1更贴合，提高了封闭效果。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
