[0020] In actual application, the artificial or external equipment places the tray (full tray) loaded with multiple round tubes on the supporting plate 8 on the circulating conveying ring 7 of the two vertical circulating conveying mechanisms 6 of the discharging device 3, the supporting plates 8 on the circulating conveying rings 7 of the two vertical circulating conveying mechanisms 6 cooperate to support two ends of the full tray, and with the rotation of the circulating conveying ring 7, the full tray is conveyed downward to the transverse conveying mechanism 5, the transverse conveying mechanism 5 conveys the tray to the detection position, the visual detection mechanism 2 visually detects the round tubes on the tray to visually detect the position and the laying angle (inclination angle) of the round tubes, so as to determine the position and the laying state of the round tubes, so that the external mechanical hand can accurately and correctly pick up the round tubes in the tray, and the accuracy and stability of the supplied round tubes are improved; when the tray is empty or when the tray is loaded with the processed round tubes, the transverse conveying mechanism 5 conveys the empty tray or the tray loaded with the processed round tubes to the receiving position, the supporting plates 8 on the circulating conveying rings 7 of the two vertical circulating conveying mechanisms 6 of the receiving device 4 lift the empty tray or the tray loaded with the processed round tubes, and with the rotation of the circulating conveying ring 7, the empty tray or the tray loaded with the processed round tubes is lifted upward, so that the artificial or external equipment takes the empty tray or the tray loaded with the processed round tubes from the receiving device 4. The automatic discharging and receiving mode of the tray is adopted to realize the automatic feeding of the round tubes, the feeding efficiency is high, the position and the laying state of the round tubes can be visually detected, and the accuracy and stability of the external mechanical hand picking up the round tubes are improved.

[0021] Specifically, the transverse conveying mechanism 5 can adopt the hollow conveying belt mechanism (such as: the conveying belt mechanism composed of two parallel and spaced conveying belt modules) in the prior art, which will not be described here.

[0022] In the embodiment, the round tube feeding machine further comprises a positioning mechanism 9 arranged on the machine table 1, and the positioning mechanism 9 is located at the detection position.

[0023] In actual application, when the transverse conveying mechanism 5 conveys the tray to the detection position, the positioning mechanism 9 positions the tray at the detection position to ensure the position accuracy and stability of the tray.

[0024] Specifically, the positioning mechanism 9 can be composed of a front material blocking module, an upward lifting mechanism, a left positioning plate and a right positioning module. The left positioning plate and the right positioning module are correspondingly arranged. The front material blocking module and the upward lifting mechanism are located in the hollow position of the transverse conveying mechanism 5. The front material blocking module, the left positioning plate and the right positioning module are distributed on the side of the upward lifting mechanism. In actual application, when the transverse conveying mechanism 5 conveys the tray to the detection position, the blocking end of the front material blocking module is lifted and blocks the tray. Then the lifting end of the upward lifting mechanism lifts the tray, so that the tray is separated from the transverse conveying mechanism 5. Then the positioning plate of the right positioning module pushes the tray to the left positioning plate. The left positioning plate cooperates with the positioning plate of the right positioning module to clamp the tray, so as to realize the positioning of the tray. When there is no circular pipe on the tray or when the tray is loaded with printed circular pipes, the positioning plate of the right positioning module releases the tray. The lifting end of the upward lifting mechanism descends and places the tray on the conveying surface of the transverse conveying mechanism 5. Then the blocking end of the front material blocking module releases the blocking of the tray. The transverse conveying mechanism 5 can convey the empty tray or the tray loaded with printed circular pipes to the material receiving position.

[0025] Therefore, the front material blocking module and the right positioning module can be composed of a cylinder and a movable plate.

[0026] In this embodiment, the circular pipe feeding machine further comprises a blocking mechanism 10 arranged on the machine table 1. The blocking mechanism 10 is located at the material receiving position. The blocking mechanism 10 is arranged outside the material receiving device 4 and in the hollow position of the transverse conveying mechanism 5. Specifically, the blocking mechanism 10 can be a fixed baffle or composed of a cylinder and a movable plate. In actual application, the transverse conveying mechanism 5 conveys the empty tray or the tray loaded with processed circular pipes to the material receiving position. The blocking mechanism 10 blocks the empty tray or the tray loaded with processed circular pipes to ensure the position accuracy and stability of the empty tray or the tray loaded with processed circular pipes at the material receiving position. At this time, the material receiving device 4 can lift the tray to receive the empty tray or the tray loaded with processed circular pipes.

[0027] In the embodiment, the visual detection mechanism 2 comprises a mounting plate 11 arranged between the top of the feeding device 3 and the top of the feeding device 3, a lifting plate 12 arranged below the mounting plate 11, a lifting driver 13 arranged on the mounting plate 11 and used for driving the lifting plate 12 to lift, and a visual detection camera 14 arranged on the lifting plate 12 and located above the transverse conveying mechanism 5. Specifically, the visual detection camera 14 can be an industrial camera, and the lifting driver 13 can be a pneumatic cylinder. In actual application, the visual detection camera 14 is used for shooting the circular pipes on the tray to visually detect the position and placement state of the circular pipes on the tray. In addition, the lifting driver 13 drives the lifting plate 12 and the visual detection camera 14 to lift, so as to adjust the height of the visual detection camera 14, thereby adjusting the focal length of the visual detection camera 14 for shooting the circular pipes, so as to meet the visual detection of circular pipes of different specifications and sizes. Of course, the following steps can also be used to visually detect the position and placement state (inclination angle) of the circular pipes. When the circular pipes are visually detected, the visual detection camera 14 first shoots the top surface of the circular pipes, then the lifting driver 13 drives the lifting plate 12 and the visual detection camera 14 to descend by a distance, and then the visual detection camera 14 shoots the top surface of the tray, and the coordinate position of the circular pipes and the placement state (inclination angle) of the circular pipes are determined by combining the shooting results of the two times and the operation of the detection system.

[0028] In the embodiment, the lifting plate 12 is provided with a guide rod 16, the mounting plate 11 is provided with a guide sleeve 15, and the guide rod 16 slidably penetrates through the guide sleeve 15. During the lifting of the lifting plate 12, the guide rod 16 and the guide sleeve 15 are in sliding fit, so as to improve the lifting stability of the lifting plate 12, thereby improving the lifting stability of the visual detection camera 14.

[0029] In the embodiment, the circulating conveying ring 7 is a conveying belt or a conveying chain, the number of the circulating conveying rings 7 is two, the two circulating conveying rings 7 are parallel and arranged at intervals, and the two ends of the supporting plate 8 are fixedly connected to the surfaces of the two circulating conveying rings 7. The structure design is beneficial to improving the stability of conveying the tray.

[0030] All the technical features in the embodiment can be freely combined according to actual needs.

[0031] The above embodiment is a preferred implementation scheme of the utility model, and the utility model can also be implemented in other ways. Any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
