[0021] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, this embodiment discloses a lifting single-ball feeding mechanism, including a cylinder 1 and a hopper 2. The hopper 2 includes a hopper body 21 and a chassis 22. The chassis 22 is fixedly connected to the lower end of the hopper body 21. The chassis 22 is fixedly installed at the upper end of the cylinder 1 by screws. The hopper 2 is fixedly installed at the upper end of the cylinder 1 through the chassis 22. The hopper 2 includes a connection hole 213. The connection hole 213 is located at the center of the lower end face of the hopper body 21. The connection hole 213 communicates with the lower end face of the chassis 22. The cylinder 1 includes a lifting column 11. The lifting column 11 can pass through the connection hole 213. The cylinder 1 can drive the lifting column 11 to lift and lower. A plurality of steel balls 4 are arranged in the hopper 2. The upper end of the lifting column 11 can extend into the hopper 2. A groove 111 is provided on the upper end face of the lifting column 11. The groove 111 can accommodate at most one steel ball 4. Each time the lifting column 11 rises, it can push out at most one steel ball 4 from the steel ball pile in the hopper body 21 through the groove 111, and push the steel ball 4 to the set height.

[0023] More preferably, the bottom surface of the hopper body 21 is a cone with a diameter gradually decreasing from top to bottom. The lifting column 11 is located at the center of the hopper body 21. The conical bottom surface of the hopper body 21 can concentrate the steel balls 4 in the hopper body 21 at the central position, and can ensure that the steel balls 4 enter the groove 111 when the lifting column 11 is in the first state.

[0024] As Figure 4 shown, more preferably, the upper end face of the lifting column 11 is a conical surface with a diameter gradually increasing from top to bottom. The conical upper end face of the lifting column 11 can ensure that when the lifting column 11 rises, only one steel ball 4 is in the groove 111 on the upper end face of the lifting column 11. The groove 111 is a conical groove with a diameter gradually decreasing from top to bottom. The conical groove can better receive the steel ball 4, and the maximum diameter of the conical groove is the same as the diameter of the steel ball 4. The included angle formed at the lower end of the cross section of the groove 111 is b, and the angle of b is 120°. After multiple tests, when the conical angle of the groove 111 is 120°, the steel ball 4 is most stably supported by the inner wall of the groove 111 in the groove 111, and the steel ball 4 will not fall off the lifting column 11 when the lifting column 11 is lifted.

[0025] As Figure 2 、 Figure 3As shown, the lifting column 11 includes a first state and a second state. In the first state, the air cylinder 1 retracts the lifting column 11, and the lifting column 11 is in the lowest position. The upper end of the lifting column 11 is located inside the connection hole 213, ensuring that the upper end of the lifting column 11 is lower than the upper end of the connection hole 213, so that the groove 111 can receive a steel ball 4. In the second state, the air cylinder 1 pushes out the lifting column 11, and the lifting column 11 is in the highest position. At this time, a steel ball 4 is located in the groove 111, and the steel ball 4 can be taken away from the lifting column 11 by an external suction device.

[0026] As Figure 1 , Figure 2 , Figure 3 shown, this embodiment further includes a monitoring device 3. The monitoring device 3 includes a transmitter 31 and a receiver 32. Two support plates 211 are symmetrically arranged on the upper end surface of the hopper 2. The support plates 211 are provided with mounting grooves 212. The transmitter 31 and the receiver 32 are respectively mounted on the two support plates 211. The outer walls of the transmitter 31 and the receiver 32 are provided with threads. Two nuts 33 are mounted on both the transmitter 31 and the receiver 32. The two nuts 33 respectively abut against the inner side wall and the outer side wall of the support plate 211. The transmitter 31 and the receiver 32 are fixed to the upper end of the hopper 2. The transmitter 31 and the receiver 32 are arranged opposite to each other. The transmitter 31 emits signal light towards the receiver 32. When the receiver 32 receives the signal, it indicates that there is no steel ball 4 at the upper end of the lifting column 11, and the lifting column 11 needs to be lifted again. When the light ray emitted by the transmitter 31 towards the receiver 32 is blocked by the steel ball 4, it is confirmed that there is a steel ball 4 on the upper end surface of the lifting column 11. The monitoring device 3 can monitor the steel ball 4 between the transmitter 31 and the receiver 32, making the automated operation more reasonable.

[0027] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
