The limiting member 802 has a groove. The limiting member 802 is mounted on the second conveying belt 801 and forms a limiting cavity 803. The detecting object is placed in the limiting cavity 803 for transport.
在本发明实施例的一个实施方式中，由于检测对象的滚针类零件非常小且重量轻，当被加速输送后，为了便于检测对象从第一输送部3更加稳定精确地进入到第二输送部5位置，在第一输送部3和第二输送部5之间设置连接软管9。在本实施例中，采用弹簧管作为连接软管，弹簧管的一端连接第一输送部3，弹簧管的另一端连接第二输送部5。当然，还可采用其他如塑料材质等软管作为连接使用。In an embodiment of the embodiment of the present invention, since the needle roller type component of the detecting object is very small and light in weight, after being acceleratedly conveyed, in order to facilitate the detection object to enter the second conveying from the first conveying portion 3 more stably and accurately At the position of the portion 5, a connection hose 9 is provided between the first conveying portion 3 and the second conveying portion 5. In the present embodiment, a spring tube is used as the connecting hose, one end of the spring tube is connected to the first conveying portion 3, and the other end of the spring tube is connected to the second conveying portion 5. Of course, other hoses such as plastic materials can also be used as the connection.
在本发明实施例的一个实施方式中，由于检测对象的滚针类零件非常小且重量轻，当被加速输送后，为了使得检测对象在第一输送部3上能够稳定，设置具有稳定元件302。在本实施例中，采用一块铁块302作为稳定元件，铁块302覆盖在第一转动辊3011和第二转动辊3012上，并且铁块302中间具有一段开口，第一转动辊3011和第二转动辊3012组成的间隙位于铁块开口中间以使得检测对象能接触到两个转动辊的转动面，从而两个转动辊的转动能带动检测对象进行转动。当然，也可以将一整块铁块分成两块分别覆盖第一转动辊3011和第二转动辊3012。In one embodiment of the embodiment of the present invention, since the needle roller type component of the detecting object is very small and light in weight, after being acceleratedly conveyed, in order to stabilize the detecting object on the first conveying portion 3, the stabilizing member 302 is provided. . In the present embodiment, an iron block 302 is used as the stabilizing element, the iron block 302 covers the first rotating roller 3011 and the second rotating roller 3012, and the iron block 302 has an opening therebetween, the first rotating roller 3011 and the second The gap formed by the rotating roller 3012 is located in the middle of the opening of the iron block so that the detecting object can contact the rotating faces of the two rotating rollers, so that the rotation of the two rotating rollers can drive the detecting object to rotate. Of course, it is also possible to divide the entire iron piece into two pieces to cover the first rotating roller 3011 and the second rotating roller 3012, respectively.
在本发明实施例的一个实施方式中，第二输送部5的第一输送皮带501为两根圆皮带组成的输送带，第一输送圆皮带5011和第二输送圆皮带5012并列设置形成检测对象的输送通道，检测对象的滚针在两个圆皮带之间的输送通道上。In an embodiment of the embodiment of the present invention, the first conveying belt 501 of the second conveying portion 5 is a conveyor belt composed of two round belts, and the first conveying round belt 5011 and the second conveying round belt 5012 are juxtaposed to form a detecting object. The conveying passage detects the needle of the object on the conveying path between the two round belts.

Under the action of the limiting block 504, the first conveying round belt 5011 and the There is a gap between the two conveying round belts 5012. Due to the small gap, on the one hand, the backlight can be irradiated to the detection object through the slit, so that the second detecting portion 6 can more clearly perform the photographing and reading the image, and on the other hand, the sorting mechanism can be conveniently used to blow through the air. The gap blows off the conveyor belt from the bottom to the top into the sorting mechanism. And because of the action of the limit block, the gap size is suitable. On the one hand, the gap is too large to cause the detection object to fall, and on the other hand, the gap is too small to cause the blow sorting unsuccessful at the time of sorting.
在本发明实施例的一个实施方式中，第二输送部6具有盖板505，盖板505位于输送带501上方覆盖整个输送区域，并且在第二检测部6和筛检部7的各区域具有开槽。这样，可以更好地避免检测对象在高速输送过程中脱落或飞溅。In an embodiment of the embodiment of the present invention, the second conveying portion 6 has a cover plate 505 which is located above the conveyor belt 501 to cover the entire conveying region, and has a region in the second detecting portion 6 and the screening portion 7 Slotted. In this way, it is possible to better prevent the detection object from falling off or splashing during high-speed conveyance.
通过本发明的滚针检测装置，虽然检测对象的滚针非常细小且重量轻，但利用加速输送 部结合第一输送部和第二输送部的结构设置，不仅快速完成外观检测，还能快速完成尺寸检测，大大提高了检测对象的检测质量和检测效率。According to the needle roller detecting device of the present invention, although the needle roller of the detection target is very small and lightweight, the structure of the first conveying portion and the second conveying portion is combined by the acceleration conveying portion, so that the appearance detection can be quickly completed and the speed can be quickly completed. Size detection greatly improves the detection quality and detection efficiency of the test object.
