DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0025] Embodiment 1: Please refer to the drawings in the following Figure 1 to the drawings in the following Figure 4 , the embodiment provides an automatic tooth branch feeding device, which comprises a tooth branch conveying mechanism 1 and a tooth branch clamping mechanism 2. The tooth branch conveying mechanism 1 at least comprises a transversely arranged vibration conveying groove 11, a vertically arranged vertical conveying groove 12 and a vertical driver 17 connected with the vertical conveying groove 12. The end of the vibration conveying groove 11 is connected with the upper end of the vertical conveying groove 12. The lower end of the vertical conveying groove 12 is provided with a tooth branch outlet 13. The lower end of the tooth branch outlet 13 is provided with a correspondingly arranged tooth branch supporting groove 14. The vertical driver 17 can drive the vertical conveying groove 12 to move along the height direction so as to drive the tooth branch outlet 13 to approach or move away from the tooth branch supporting groove 14. The vertical conveying groove 12 is further provided with a tooth branch limiting opening 15 and a top pressing driver 16 correspondingly arranged with the tooth branch limiting opening 15. The top pressing driver 16 is provided with a limiting pressing piece capable of extending out of or retracting into the tooth branch limiting opening 15. The tooth branch clamping mechanism 2 at least comprises a movably arranged tooth branch clamp 21, which is used for clamping and conveying a tooth branch between the tooth branch outlet 13 and the tooth branch supporting groove 14. The vibration conveying groove 11 in the tooth branch conveying mechanism 1 continuously feeds tooth branches into the vertical conveying groove 12. When a tooth branch extends out of the tooth outlet 13 and abuts against the tooth branch supporting groove 14, the tooth branch clamp 21 is located at the upper side of the tooth branch supporting groove 14 and is in a clamping state. Since a small part of the upper end of the tooth branch is still in the vertical conveying groove 12, the tooth branch will not fall out of the device due to tilting. Meanwhile, the next tooth branch located at the upper side of the tooth branch is just at the tooth branch limiting opening 15 in the vertical conveying groove 11 and is pressed by the limiting top pin driven by the top pressing driver 16. After the tooth branch clamp 21 clamps the tooth branch, the vertical driver 17 drives the vertical conveying groove 12 to move upward by a certain height, so that the clamped tooth branch is completely separated from the vertical conveying groove 12. At this time, the tooth branch clamp 21 moves to feed the tooth branch to a waiting pressing station. After the tooth branch clamp 21 is reset, the top pressing driver 16 drives the limiting top pin to retract to release the next tooth branch, so that the tooth branch clamp 21 repeats the clamping work.

[0026] The vibration conveying groove 11 is horizontally inclined and connected with a vibrator 111, and the first end of the vibration conveying groove 11 is higher than the end. The vibrator 111 drives the vibration conveying groove 11 to vibrate to convey the tooth branches from the first end to the end, wherein preferably, the tooth branch conveying mechanism 1 further comprises a roller corresponding to the first end of the vibration conveying groove 11, and the inner circumferential side of the roller is provided with a plurality of curved grooves at equal intervals, and the curved grooves circulate through the low position to the high position of the first end of the vibration conveying groove with the rotation of the roller, so that the tooth branches are lifted to a certain height, and the tooth branches will fall into the vibration conveying groove 11. The conveying mode refers to the principle of the screw feeder, and the purpose is to lift the scattered tooth branches and arrange them in order in the vibration conveying groove 11 and transport them to the vertical conveying groove 12.

[0027] The tooth branch channel in the vertical conveying groove 12 is provided with a sensor 18, and the sensor 18 is electrically connected with the vibrator 111. When the tooth branches in the vertical conveying groove 12 are accumulated to the height of the sensor 18, the sensor 18 will send a signal to stop the vibrator 111, so that the vibration conveying groove 11 stops conveying the tooth branches to the vertical conveying groove 12, and the accumulation of the tooth branches in the vertical conveying groove 12 is avoided.

[0028] The tooth branch clamping mechanism 2 further comprises a tooth branch clamping height adjustment module 22, a first linear module 23 for driving the tooth branch clamp 21 to move along the length direction, and a second linear module 24 for driving the tooth branch clamp 21 to move along the width direction. The arrangement of the height adjustment module 22, the first linear module 23 and the second linear module 24 can realize the accurate movement of the tooth branch clamp 21 in the space rectangular coordinates, and improve the clamping accuracy.

[0029] The tooth branch clamp 21 is detachably installed on the tooth branch clamping height adjustment module 22, the tooth branch clamping height adjustment module 22 is arranged on the first linear module 23, the first linear module 23 is arranged on the second linear module 24, and the head of the tooth branch clamp 21 is provided with a V-shaped clamping groove 211, so that the tooth branch clamp 21 can realize more firm and stable clamping of the tooth branches.

[0030] The automatic tooth branch feeding device 2 further comprises a tooth branch oiling mechanism 3, which comprises an oil storage groove 31 arranged at the end of the tooth branch supporting groove 14, and a rotating oil dipping roller 32 is arranged in the oil storage groove 31; the rotating circumferential side of the oil dipping roller 32 is provided with a V-shaped groove 33, and the V-shaped groove 33 is arranged opposite to the tooth branch supporting groove 14. When the tooth branches are translated and sent out in the tooth branch supporting groove 14, the lower end of the tooth branches will touch and pass through the V-shaped groove 33 on the translation path, so as to realize the effect of automatic oiling, which is more beneficial to the press fitting.

[0031] The rotation center of the oil-dipping roller 32 is provided with a protruding shaft 321, the shaft 321 is nested with a shaft sleeve 322, the shaft sleeve 322 is longitudinally movably arranged in the oil storage groove 31; the shaft sleeve 322 and the oil storage groove 31 are provided with a spring 34, one end of the spring 34 abuts against the lower end of the shaft sleeve 322, and the other end abuts against the bottom of the oil storage groove 31. When the lower end of the toothpick abuttingly touches the oil-dipping roller 32, the oil-dipping roller 32 will be instantaneously pressed downward and sink, and the spring 34 can play a buffering role in the moderate sinking of the oil-dipping roller 32.

[0032] Preferably, the toothpick conveying mechanism 1 is provided in two groups, the toothpick clamp 21 is movably arranged between the toothpick outlet 13 and the toothpick supporting groove 14 of each group of toothpick conveying mechanisms 1 to clamp and convey toothpicks, different specifications of toothpicks can be simultaneously conveyed and clamped, and the toothpick conveying mechanism 1 has strong versatility.
