DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 4 As shown, a feeding and detecting device for packaging bottles comprises a feeding device 1 for loading packaging bottles and a detecting device 2 for detecting packaging bottles, a mechanical arm 3 for grabbing packaging bottles is arranged between the feeding device 1 and the detecting device 2, the feeding device 1 comprises a feeding table 11 connected in sequence by several layers, a feeding turntable 14 rotatably connected to the feeding table 11 is installed on the feeding table 11, and a plurality of feeding plates 18 for loading packaging bottles are formed on the feeding turntable 14; an identification device 4 electrically connected to the mechanical arm 3 is arranged on one side of the feeding device 1, and a plurality of identification sensors 41 for identifying the loading conditions of packaging bottles on the plurality of feeding tables 11 are installed on the identification device 4.

[0024] The detection device 2 includes a frame and a conveyor belt arranged on the frame, and the frame is provided with a visual identifier arranged toward the conveyor belt. The visual identifier is used to photograph the packaging bottles on the conveyor belt and transmit the photographed images to the industrial control computer. The industrial control computer compares the photographed images with the pre-imported sample 3D drawings to determine the integrity and model of the packaging bottles.

[0025] The robot arm 3 is a six-axis robot arm, and the movement path of the robot arm 3 is planned. The movement path of the robot arm 3 includes grabbing the packaging bottles from the feeding device 1 to the detection device 2, and the movement path is single, ensuring that the positions of the packaging bottles grabbed by the robot arm 3 are consistent each time, thereby ensuring that the initial packaging bottle positions on the detection device 2 are the same, which is convenient for the subsequent detection device 2 to detect and identify the packaging bottles.

[0026] A servo motor 15 for driving the feeding turntable 14 to rotate is installed in the feeding table 11, and a rotating shaft 16 that rotates synchronously with the feeding turntable 14 is provided at the output end of the servo motor 15. The servo motor 15 is fixedly connected to the feeding table 11 by bolts. The feeding turntable 14 is arranged on the upper surface of the feeding table 11, and the bottom of the feeding turntable 14 is abutted against the feeding table 11, so that the feeding turntable 14 is supported and abutted under the action of the feeding table 11.

[0027] A mounting hole 13 for mounting a rotating shaft 16 is formed on the feeding table 11, and a plurality of support columns 12 arranged along the circumferential direction of the mounting hole 13 are provided between adjacent feeding tables 11. A bearing matching the rotating shaft 16 can be installed in the mounting hole 13 to ensure the rotation stability of the rotating shaft 16. The rotating shaft 16 and the feeding turntable 14 are connected by a key and a keyway, and the feeding turntable 14 is synchronously driven to rotate under the rotation action of the rotating shaft 16, so that the rotation of the feeding turntable 14 is controlled by the servo motor 15.

[0028] A plurality of support columns 12 are arranged around the feeding turntable 14, and the support columns 12 are used to realize the connection between adjacent feeding tables 11, and the support columns 12 are used to support the distance between adjacent feeding tables 11, ensuring that the required packaging bottles can be placed between adjacent feeding tables 11. At the same time, the support columns 12 surround the feeding turntable 14, and the rotation of the feeding turntable 14 does not interfere with the setting of the support columns 12.

[0029] The feeding device 1 includes a weighing platform 6 and a protective frame 7 for protecting the weighing platform 6. A plurality of feeding platforms 11 are arranged on the weighing platform 6. The weighing platform 6 is used to detect the overall weight of the plurality of feeding platforms 11. When the packaging bottles on the plurality of feeding platforms 11 are sequentially grabbed by the robotic arm 3, the weight of the overall feeding platform 11 decreases, so that the number of packaging bottles on the plurality of feeding platforms 11 can be identified through the weighing platform 6, so as to facilitate timely loading of the packaging bottles on the plurality of feeding platforms 11.

[0030] A plurality of feed plates 18 are arranged along the circumference at the center of the feed turntable 14, and a clamping boss 17 corresponding to each feed plate 18 is formed in the middle of the feed turntable 14. The clamping boss 17 is used to position the packaging bottles placed on the feed turntable 14 to ensure the stability of the packaging bottles during the rotation of the feed turntable 14.

[0031] The clamping boss 17 includes a boss body 171 located in the middle of the feeding turntable 14 and a plurality of side bosses 172 arranged along the length direction of the side edges of each feeding plate 18. The side bosses 172 are formed on opposite sides of each feeding plate 18. A feeding position 19 for abutting against the packaging bottle is formed between the side bosses located on opposite sides of the feeding plate 18 and the boss body 171. The boss body 171 and the plurality of side bosses 172 are an integrated structure.

[0032] Under the action of the feeding position 19, when the packaging bottle is placed on the feeding position 19, the end of the packaging bottle abuts against the boss body 171, and the two sides of the packaging bottle abut against the relatively arranged side bosses 172 at the same time, thereby achieving a stable setting of the packaging bottle under the action of the boss body 171 and the side bosses 172, ensuring the stability of the packaging bottle under the rotation of the feeding turntable 14.

[0033] A recovery device 5 for conveying the inspected packaging bottles is also provided on one side of the robot arm 3 .

[0034] During actual use, the packaging bottles on the feeding table 11 are grabbed by the robot arm 3, and the robot arm 3 grabs the packaging bottles along a pre-set grabbing trajectory to ensure that the robot arm 3 is in the same grabbing position when grabbing packaging bottles at the same height, and the feeding turntable 14 is used to transfer the positions of packaging bottles at the same height to meet the grabbing requirements of the robot arm 3, so that under the action of the robot arm 3 with the same motion trajectory, the packaging bottles placed on the detection device 2 are in the same initial position, which is convenient for the detection of the packaging bottles by the detection device 2.
