The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the utility model and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The utility model will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1-2, as a preferred embodiment of the present invention, there is provided a steel ball separating device, which comprises a base 1, a sliding seat 2 fixedly connected to the base 1, and a base 3, wherein a steel ball bottle 4 for storing steel balls is fixedly connected to the upper end of the base 3 and extends into the base 3, as shown in fig. 4-5, the lower end of the steel ball bottle 4 is open, a first conveying channel 9 downward along the gravity direction is formed at the lower end of the steel ball bottle 4 in the base 3, the caliber of the first conveying channel 9 is slightly larger than the outer diameter of the steel balls, so that the steel balls are stacked and arranged in the first conveying channel 9 from top to bottom along the gravity direction, a slide way 10 perpendicular to the first conveying channel 9 is formed at the outlet of the first conveying channel 9, a separating slider 5 sliding back and forth along the slide way 10 is slidably connected to the slide way, a separating hole 51 for accommodating a single steel ball is formed on the separating slider 5, when the material distributing slide block 5 slides, the material distributing hole 51 is aligned with the lower end outlet of the first conveying channel 9, so that a single steel ball falls in the material distributing hole 51, the material distributing slide block 5 continuously slides, the single steel ball is pushed to move in the slide way 10, and the material distribution of the steel ball is realized.

Continuing to refer to fig. 5, a blanking hole 21 is arranged on the slide way 10, the lower end of the blanking hole 21 is connected with a second conveying channel 11 which is downward along the gravity direction, referring to fig. 5, 6 and 7 sequentially, the material distributing slide block 5 retreats in sequence in a working process to enable the material distributing hole 51 to be aligned with the lower end outlet of the first conveying channel 9, a single steel ball falls in the material distributing hole 51, then the single steel ball is advanced to push the single steel ball to move in the slide way 10, and finally the steel ball enters the blanking hole 21 and is conveyed downward along the second conveying channel 11.

The steel ball distributing device provided by the embodiment is utilized to realize the automation of single steel ball distribution, and the second conveying channel 11 is arranged, so that the steel balls can automatically enter the subsequent conveying or assembling step by virtue of gravity. In other embodiments, the subsequent conveying path of the steel balls can adopt other conveying structures and manners instead of the second conveying channel 11, for example, after the steel balls are separated, the steel balls are sucked up by a suction nozzle for automatic assembly.

Because the steel balls are magnetic and are easily stained with oil stains in the conveying process, the steel balls are likely to be clamped in the lower end outlet of the first conveying channel 9 or the blanking hole 21 in the conveying process of the material distributing slide block 5, and therefore, in order to further improve the reliability of the steel ball material distributing device and reduce the failure rate, the steel ball material distributing device is further provided with an air blowing device to assist the steel balls to fall from the first conveying channel 9 or the blanking hole 21. As shown in fig. 5, a first gas channel 22 is opened above the blanking hole 21 toward the blanking hole 21, and gas is introduced into the first gas channel 22 by a blowing device (not shown), for example, a nitrogen gas source externally connected with a gas pipe, so as to blow the blanking hole 21, thereby assisting the falling of the steel balls from the blanking hole 21. Similarly, referring to fig. 8, a second gas channel 23 connected to the first conveying channel 9 may be further formed on the base 3, and a blowing device is used to introduce gas into the second gas channel 23 so as to blow gas downwards along the first conveying channel 9, thereby assisting the steel balls to fall from the first conveying channel 9.

In the embodiment, the first gas channel 22 and the second gas channel 23 are respectively communicated with the blanking hole 21 and the first conveying channel 9, so that the gas guiding effect can be improved, and in other embodiments, the blowing device can be used for blowing gas directly above the arrangement of the blanking hole 21 or the first conveying channel 9.

The passages in this embodiment, such as a delivery channel 9, chute 10, blanking hole 21, first gas channel 22, and second gas channel 23, are formed in the base 3, but in other embodiments, tubular conduit structures may be used instead.

Referring to fig. 4, a hall sensor 12 is further disposed outside the second conveying passage 11 to sense whether the steel balls pass through smoothly, and when a problem occurs in the detection, the apparatus can be quickly stopped to perform maintenance. In other embodiments, the hall sensor 12 may be other sensing devices, such as a photosensor.

And the lower end of the second conveying channel 11 is of a gradually contracted conical barrel-shaped structure so as to guide the discharging position of the steel balls and improve the accuracy of the steel ball conveying position.

In the embodiment, the material distributing slide block 5 is driven by the air cylinder 6 to slide, and the air cylinder 6 can be replaced by other driving devices, such as a motor and an oil cylinder.

In this embodiment, the first conveying passage 9 and the second conveying passage 11 are vertically extended downward in the direction of gravity, and may be obliquely extended downward in other embodiments, which does not affect the conveyance of the steel balls.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
