[0059] Example 2
[0060] like Figure 2 As shown, the method includes the following steps:
[0061] Step 1: Obtain the cylinder information and configure the automatic packaging program in the central control system according to the cylinder information;
[0062] For example, information such as height, volume, and diameter of the gas cylinder needs to be established in advance in the database and bound to the RFID card. The central control system transmits the automatic packaging program of the gas cylinder to the three-axis gantry robot, the conveyor line, the bottle cap removal machine, the valve photographing robot, the torque detection robot, the central control system, the bagging machine, the sealing machine, the labeling robot, and the overall photographing robot.
[0063] Step 2: After the program starts running, the three-axis gantry robot automatically grabs the gas cylinder and places it on the conveyor line;
[0064] Before the three-axis truss robot can grab the cylinder, the cylinder needs to be manually moved to the preparation area.
[0065] Step 3: After the bottle cap removal robot identifies the gas cylinder in place, it removes the bottle cap from the gas cylinder.
[0066] Once the gas cylinder is in place, a visual positioning system is used to detect and locate its position from a distance.
[0067] Step 4: The robotic arm needs to take photos from different angles according to the set program and upload them to the storage system;
[0068] The aforementioned robotic arm uses a high-definition 3D camera to photograph the appearance of the bottle valve;
[0069] The different angles mentioned are divided into four directions according to the shooting direction: 0°, 90°, 180°, and 270° perpendicular to the cylinder, and 0°, 90°, 180°, and 270° angled downwards at 45°.
[0070] Step 5: The torque detection robot arm performs torque detection on the upper valve torque and the valve handle torque.
[0071] The aforementioned inspection robot achieves equipment compatibility for different valve handles by quickly changing the contour tooling for turning the handle;
[0072] The upper valve torque is set to 180-240 N·m, with 200 N·m being preferred.
[0073] The handle torque is set to 8-12 N.M, with 9 N.M being preferred.
[0074] Step 6: The labeling robot automatically prints and affixes labels based on the cylinder information;
[0075] The labeling robot uses laser vision technology to precisely locate the label placement position.
[0076] Step 7: Based on the cylinder information, the bagging machine performs heat shrink wrapping on cylinders of different models.
[0077] The information about the gas cylinder is transmitted from the central control system to the bagging machine, which then selects different sealing bags based on the gas cylinder information.
[0078] The bagging machine uses negative pressure to open the bag and then covers the entire heat-shrink film onto the cylinder.
[0079] Step 8: The sealing machine heats the air and blows it onto the surface of the steel cylinder to achieve sealing of the steel cylinder surface;
[0080] The sealing machine uses a heating rod to heat the air, and then a hot air blower blows the hot air to the air outlet. The film assembly moves up and down with the air outlet to seal the thermoplastic film on the cylinder.
[0081] Step 9: The robotic arm takes photos of the packaged steel cylinders and uploads them to the storage system.
[0082] The overall photography robotic arm described above uses a high-definition 3D camera, is equipped with a light source and an automatic lifting platform;
[0083] The aforementioned cylinder photography sampling method allows for sampling at any angle along the cylinder's axial direction.
[0084] Example 3
[0085] The automatic cylinder packaging system includes a three-axis gantry robot 1, a conveyor line 2, a bottle cap removal machine 3, a valve photographing robot 4, a torque detection robot 5, a central control system 6, a bagging machine 7, a sealing machine 8, a labeling robot 9, and an overall photographing robot 10; (Refer to...) Figure 1 When conveyor line 2 is working, it forms a closed-loop conveyor counterclockwise. A three-axis gantry robot 1 is installed at the starting position 1 of conveyor line 2 and fixed to the ground. The central control system 6 issues commands, and the three-axis gantry robot 1 grabs the cylinders onto and off the conveyor line. Bottle cap removal machine 3, valve photographing robot 4, torque detection robot 5, labeling robot 9, bagging machine 7, sealing machine 8, and overall photographing robot 10 are distributed sequentially along conveyor line 2 at stations numbered 2 to 10 and fixed to the ground. The central control system 6 controls the conveyor line to transport the cylinders to stations 2 to 10 sequentially. When a cylinder is received at a corresponding station, the central control system 6 controls that station to begin its work. After completion, conveyor line 2 transports the cylinder to the next station until all stations are working. Finally, the three-axis gantry robot 1 grabs the cylinder and places it in the storage area.
