[0036] Please also read Figures 1 to 4 Now, a circular continuous feeding device provided in an embodiment of the present application is described. The circular continuous feeding device comprises a frame plate 101, a vertical plate 102, a slide seat 105, a suction cup 106 and a driving mechanism. Among them:

[0037] The vertical plate 102 is mounted on the frame plate 101 and forms an annular side wall perpendicular to the frame plate 101. The vertical plate 102 forms an annular track groove 103 that is recessed inward from the annular side wall along the thickness direction. The opposite sides of the annular track groove 103 respectively form a sinking section 104 that sinks along the height direction of the vertical plate 102. The slide 105 is slidably connected to the vertical plate 102 through the annular track groove 103 and provided with a sliding guide by the annular track groove 103. The suction cup 106 is connected to the slide 105 through a material taking arm 107 connected to the slide 105 and is used to take materials. The driving mechanism is transmission-connected to the slide 105 and is used to drive the slide 105 to move in the annular track groove 103. For the convenience of explanation, the feeding conveyor belt 200 arranged on one side of the annular continuous feeding device is introduced in this embodiment for explanation. It can be understood that the end of the feeding conveyor belt 200 is close to the sinking section 104 on one side of the annular track groove 103.

[0038] According to the above structure provided in the present embodiment, in the annular continuous feeding device provided in the present embodiment, an annular track groove 103 recessed in the thickness direction is formed on the annular side wall of the vertical plate 102 and sinking sections 104 are formed on the opposite sides of the annular track groove 103 in the height direction of the vertical plate 102. In the process of the slide 105 moving along the annular track groove 103, the slide 105 can operate along the annular path under the guidance of the annular track groove 103 and descend in the sinking section 104 of the annular track groove 103 to pick up materials. In this way, the suction cup 106 connected to the slide 105 through the picking arm 107 can transport the material from one side of the vertical plate 102 to the other side and complete the feeding operation. Since the slide 105 can operate continuously along the annular track groove 103, the feeding efficiency of the annular continuous feeding device in the present application can be significantly improved, which is far superior to the prior art.

According to the above structure provided in this embodiment, the servo motor 111 can drive the chain 108 through the active sprocket 109 and the passive sprocket 110. The guide rod 112 driven by the chain 108 can move around the annular side wall of the vertical plate 102 and drive the slide 105 to move in the annular track groove 103. It can not only stably drive the slide 105, but also because the guide rod 112 is also slidably connected to the slide 105, it can also provide guidance for the movement of the slide 105 in the height direction relative to the vertical plate 102, thereby having a better driving effect.

[0040] In another embodiment of the present application, please refer to Figures 1 to 4 The servo motor 111 and the chain 108 are arranged on opposite sides of the frame plate 101. According to the above structure provided in this embodiment, the chain 108 and the servo motor 111 arranged on both sides of the frame plate 101 can avoid mutual interference, which is conducive to the annular continuous feeding device provided in this embodiment being used for feeding stably for a long time.

According to the above structure provided in this embodiment, the driving shaft 113 and the supporting shaft 114 can be better supported by the support plate 115 and the upper connecting plate 116 connected to the support plate 115, which is conducive to making the guide rod 112 rotate more stably around the vertical plate 102 and further improving the feeding efficiency of the annular continuous feeding device in this embodiment.

[0043] In another embodiment of the present application, please refer to Figures 1 to 4, multiple groups of guide rods 112 are evenly arranged along the extension direction of the chain 108, multiple groups of slides 105, material-collecting arms 107 and suction cups 106 are respectively arranged corresponding to the guide rods 112, and the annular continuous feeding device also includes an air slide ring 117 for supplying air to the multiple groups of suction cups 106 and multiple groups of air pipes 118 connected between the air slide ring 117 and the multiple groups of suction cups 106.

[0044] In another embodiment of the present application, please refer to Figures 1 to 4 The air slip ring 117 includes a stator part 119 and a rotor part 120 rotatably mounted on the stator part 119. The stator part 119 is fixedly mounted on a motor seat for mounting on the servo motor 111 through a support plate 121. A hollow guide tube 123 with a hollow interior and openings at both ends is coaxially connected to the rotor part 120 through a transition sleeve 122. The upper end of the hollow guide tube 123 passes through the upper connecting plate 116. All of the multiple groups of air pipes 118 pass through the hollow guide tube 123 to connect the suction cup 106 and the rotor part 120 of the air slip ring 117. According to the above structure provided in this embodiment, all of the multiple groups of air pipes 118 pass through the hollow guide tube 123, which is conducive to better arranging the multiple groups of air pipes 118, and is conducive to avoiding the situation of knotting and entanglement between the multiple groups of air pipes 118, and can further improve the feeding efficiency of the annular continuous feeding device in this embodiment.

[0045] In another embodiment of the present application, please refer to Figures 1 to 4A driving synchronous wheel 124 is coaxially mounted on the driving shaft 113, a passive synchronous wheel 125 is coaxially mounted on the outside of the hollow guide cylinder 123, the driving synchronous wheel 124 and the passive synchronous wheel 125 are connected through a synchronous belt 126, and the hollow guide cylinder 123 is driven by the servo motor 111 through the passive synchronous wheel 125 and the driving synchronous wheel 124. According to the above structure provided in the present embodiment, by means of the active synchronous wheel 124 and the passive synchronous wheel 125 provided between the hollow guide cylinder 123 and the driving shaft 113, the servo motor 111 can be used to drive the active sprocket 109 and the rotor portion 120 of the air slip ring 117 at the same time, which is not only conducive to avoiding the provision of a separate driving mechanism for the air slip ring 117, but also can make the rotation of the hollow guide cylinder 123 and the rotation of the rotor portion 120 of the air slip ring 117 more adapted to the rotation of the active sprocket 109, which is conducive to further avoiding the occurrence of knotting and entanglement between multiple groups of air pipes 118 and improving the feeding efficiency of the annular continuous feeding device in the present embodiment. In addition, since the hollow guide cylinder 123 also rotates synchronously, the wear of the air pipe 118 on the mouth surface of the hollow guide cylinder 123 is effectively avoided, the service life of the air pipe 118 is significantly extended, and the use stability of the entire device is ensured.

[0046] In another embodiment of the present application, please refer to Figures 1 to 4 , the speed ratio of the driving sprocket 109 and the hollow guide cylinder 123 is equal to the ratio of the circumference of the annular track groove to the circumference of the pitch circle of the driving sprocket 109. According to the above structure provided in this embodiment, the hollow guide cylinder 123 and the driving sprocket 109 adopt the above speed ratio, which is conducive to the driving sprocket 109 driving the chain 108 to drive the slide 105 to run one circle along the annular track groove 103, and the hollow guide cylinder 123 and the rotor part 120 also just rotate one circle, synchronously with the slide 105.
