具体实施方式detailed description
下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.
在工业自动化的工件自动传输过程,例如,对于半导体行业晶片加工输送过程,机械手对晶片在不同工位之间的传送需要借助于定位销和支架来完成。但由于定位销和支架加 工生产及安装均存在误差,因此,对于晶片的位置无法进行调节。本发明着力解决上述技术问题。In the automated automated workpiece transfer process, for example, for the semiconductor industry wafer processing transport process, the transfer of the robot to the wafer between different stations needs to be done by means of locating pins and brackets. But because of the positioning pin and bracket plus There are errors in production and installation, so the position of the wafer cannot be adjusted. The present invention addresses the above technical problems.
下面参照图1-图5描述根据本发明实施例的定位组件100,该定位组件100大体可以包括:支架10和多个定位销20。该定位组件100可以用于晶片传送装置中,以满足晶片在传输过程中对晶片位置进行准确调节。A positioning assembly 100 in accordance with an embodiment of the present invention, which may generally include a bracket 10 and a plurality of positioning pins 20, is described below with reference to FIGS. The positioning assembly 100 can be used in a wafer transfer apparatus to meet the wafer's accurate adjustment of wafer position during transport.
具体地,如图1和图2所示,多个定位销20沿支架10的周向方向间隔设置且可旋转地设在支架10上。换言之,支架10的周向方向上设有一个以上的定位销20,且定位销20相对支架10可旋转。Specifically, as shown in FIGS. 1 and 2, a plurality of positioning pins 20 are spaced apart in the circumferential direction of the bracket 10 and rotatably provided on the bracket 10. In other words, more than one positioning pin 20 is provided in the circumferential direction of the bracket 10, and the positioning pin 20 is rotatable relative to the bracket 10.
如图3-图5所示,每个定位销20可以包括:用于支承工件40的定位板21、定位板21的上表面设有定位凸起22,定位板21的下表面贴合于支架10的上表面且设有转轴23。As shown in FIG. 3 to FIG. 5, each of the positioning pins 20 may include: a positioning plate 21 for supporting the workpiece 40. The upper surface of the positioning plate 21 is provided with a positioning protrusion 22, and the lower surface of the positioning plate 21 is attached to the bracket. The upper surface of 10 is provided with a rotating shaft 23.
其中,如图4和图5所示,转轴23的中心轴线与定位凸起22的中心轴线不重合,通过旋转定位销20可改变位于支架10的多个定位凸起22之间的水平距离,从而对工件40位置进行有效调节。也就是说,多个定位凸起22可以限定工件40在水平方向的自由度,由于转轴23的中心轴线与定位凸起22的中心轴线不在同一竖直方向上,定位凸起22在水平方向的位置随着转轴23的旋转而发生改变,即定位板21用于支承工件40的面积会随着转轴23的旋转而发生改变。例如,图5所示,当转轴23顺时针方向旋转时,定位凸起22水平方向的位置向右移动,定位板21用于支承工件40的面积随之减小,工件40也随之向右移动,从而实现对工件40位置进行调节,其中,图5中虚线示出了工件40与定位凸起22随着转轴23的旋转对应的位置关系变化。Wherein, as shown in FIG. 4 and FIG. 5, the central axis of the rotating shaft 23 does not coincide with the central axis of the positioning protrusion 22, and the horizontal distance between the plurality of positioning protrusions 22 of the bracket 10 can be changed by rotating the positioning pin 20. Thereby the position of the workpiece 40 is effectively adjusted. That is, the plurality of positioning projections 22 can define the degree of freedom of the workpiece 40 in the horizontal direction. Since the central axis of the rotating shaft 23 is not in the same vertical direction as the central axis of the positioning projection 22, the positioning projection 22 is horizontal. The position changes as the rotation of the rotary shaft 23, that is, the area of the positioning plate 21 for supporting the workpiece 40 changes with the rotation of the rotary shaft 23. For example, as shown in FIG. 5, when the rotating shaft 23 rotates clockwise, the position of the positioning projection 22 in the horizontal direction moves to the right, and the area of the positioning plate 21 for supporting the workpiece 40 is reduced, and the workpiece 40 is also turned to the right. The movement is performed to thereby adjust the position of the workpiece 40, wherein the broken line in FIG. 5 shows the positional relationship of the workpiece 40 and the positioning projection 22 corresponding to the rotation of the rotating shaft 23.
因此,在生产过程中,通过旋转任意一个定位销20均可以对工件40的位置进行调节,以满足生产的需要,从而有效解决工件40位置无法进行调节的的问题,保证了生产的正常稳定进行,且避免了对定位组件100进行修整而产生不必要的费用。Therefore, in the production process, the position of the workpiece 40 can be adjusted by rotating any one of the positioning pins 20 to meet the needs of production, thereby effectively solving the problem that the position of the workpiece 40 cannot be adjusted, and ensuring normal and stable production. And unnecessary trimming of the positioning assembly 100 is avoided.
简言之,根据本发明实施例的定位组件100,由于转轴23的中心轴线与定位凸起22的中心轴线不重合,可以通过旋转定位销20来改变定位凸起22之间的水平距离,进而改变定位板21用于支承工件40的面积,从而实现对工件40位置的调节,保证了生产的正常稳定进行,降低了生产成本。In short, according to the positioning assembly 100 of the embodiment of the present invention, since the central axis of the rotating shaft 23 does not coincide with the central axis of the positioning protrusion 22, the horizontal distance between the positioning protrusions 22 can be changed by rotating the positioning pin 20, thereby The positioning plate 21 is used to support the area of the workpiece 40, thereby realizing the adjustment of the position of the workpiece 40, ensuring normal and stable production, and reducing production costs.
在本发明的一些实施例中,参考图1结合图3-图5,支架10可以包括:定位柱11和多个支撑条111。In some embodiments of the present invention, referring to FIG. 1 in conjunction with FIGS. 3-5, the bracket 10 may include a positioning post 11 and a plurality of support bars 111.
具体地,多个支撑条111呈射线状分布在定位柱11的外周,每个支撑条111的一端(如图1中的支撑条的内端)与定位柱11相连,另一端(如图1中的支撑条的外端)向外延伸。Specifically, a plurality of support bars 111 are radially distributed on the outer circumference of the positioning post 11, and one end of each support bar 111 (such as the inner end of the support bar in FIG. 1) is connected to the positioning post 11 and the other end (see FIG. 1). The outer end of the support strip in the middle extends outward.
每个定位销20均包括定位板21、位于定位板21上表面的定位凸起22和位于定位板21下表面的转轴23。其中,定位板21的下表面贴合于支架10的上表面。 Each of the positioning pins 20 includes a positioning plate 21, a positioning projection 22 on the upper surface of the positioning plate 21, and a rotating shaft 23 on the lower surface of the positioning plate 21. The lower surface of the positioning plate 21 is attached to the upper surface of the bracket 10.
如图5所示,工件40的下表面贴合于定位板21的上表面,且工件40的端面与定位凸起22的外表面接触。As shown in FIG. 5, the lower surface of the workpiece 40 is attached to the upper surface of the positioning plate 21, and the end surface of the workpiece 40 is in contact with the outer surface of the positioning projection 22.
有利地,定位凸起22的外表面为曲面。这样,定位销20在旋转过程中,放置在定位板21上的工件40与定位凸起22表面之间的摩擦力较小。由此,可以避免在改变工位位置时对工件40带来损伤。Advantageously, the outer surface of the locating projection 22 is a curved surface. Thus, during the rotation of the positioning pin 20, the friction between the workpiece 40 placed on the positioning plate 21 and the surface of the positioning projection 22 is small. Thereby, it is possible to avoid damage to the workpiece 40 when the position of the station is changed.
可选地,定位凸起22与定位板21同轴设置。由此,可以简化用于制造定位组件100的模具,易于定位组件100的生产加工。Optionally, the positioning protrusion 22 is disposed coaxially with the positioning plate 21. Thereby, the mold for manufacturing the positioning assembly 100 can be simplified, and the production process of the assembly 100 can be easily positioned.
有利地,转轴23一体形成在定位板21的下表面。由此,可以提高转轴23与定位板21之间的连接强度,且便于定位组件100的生产加工。Advantageously, the rotating shaft 23 is integrally formed on the lower surface of the positioning plate 21. Thereby, the connection strength between the rotating shaft 23 and the positioning plate 21 can be improved, and the production process of the positioning assembly 100 can be facilitated.
在本发明另一些实施例中,如图2所示,支架10可以为环形板,环形板包括:两个第一弧形板121、安装台122和两个第二弧形板123。In other embodiments of the present invention, as shown in FIG. 2, the bracket 10 may be an annular plate including: two first curved plates 121, a mounting table 122, and two second curved plates 123.
具体地,多个安装台122分别设在第一弧形板121的两端且向上延伸,定位销20设在安装台122的上端。第一弧形板121和第二弧形板123同心设置,第二弧形板123连接在相邻的两个安装台122之间。换言之,第一弧形板121和第二弧形板123在竖直方向处于不同高度,安装台122连接在第一弧形板121和第二弧形板123之间。Specifically, a plurality of mounting stages 122 are respectively disposed at two ends of the first curved plate 121 and extend upward, and the positioning pin 20 is disposed at an upper end of the mounting base 122. The first curved plate 121 and the second curved plate 123 are concentrically arranged, and the second curved plate 123 is connected between the adjacent two mounting stages 122. In other words, the first curved plate 121 and the second curved plate 123 are at different heights in the vertical direction, and the mounting table 122 is coupled between the first curved plate 121 and the second curved plate 123.
如图2所示,定位销20设在安装台122的内侧,且由于第一弧形板121和第二弧形板123具有高度差,工件40可以从第一弧形板121的上方放置或离开定位板21。从而使得定位组件100的结构设计更加合理。As shown in FIG. 2, the positioning pin 20 is disposed inside the mounting table 122, and since the first curved plate 121 and the second curved plate 123 have a height difference, the workpiece 40 may be placed from above the first curved plate 121 or Leaving the positioning plate 21. Thereby, the structural design of the positioning assembly 100 is made more reasonable.
可选地,在本发明的再一些实施例中,定位组件100还可以包括:紧固螺钉30。转轴23的下表面设有定位孔,紧固螺钉30穿设支架10的下表面伸入定位孔内。可以理解的是,当定位凸起22的水平位置调节到适当位置时,可以通过紧固螺钉30将定位组件100固定在支架10上,提高定位组件100的稳定性,防止定位组件100受到外力因素发生变动,从而保证整个生产正常稳定进行。Optionally, in still other embodiments of the present invention, the positioning assembly 100 may further include: a fastening screw 30. The lower surface of the rotating shaft 23 is provided with a positioning hole, and the fastening screw 30 extends through the lower surface of the bracket 10 into the positioning hole. It can be understood that when the horizontal position of the positioning protrusion 22 is adjusted to an appropriate position, the positioning assembly 100 can be fixed on the bracket 10 by the fastening screw 30, thereby improving the stability of the positioning assembly 100 and preventing the positioning assembly 100 from being subjected to an external force factor. Changes have occurred to ensure that the entire production is stable and stable.
