Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled sample sampling in the steel industry, and particularly relates to a cold-rolled sample sampling system. Background Art

[0002] Using hot-rolled steel coils as raw materials, after pickling to remove the oxide scale, cold tandem rolling is carried out, and the finished product is cold-rolled hard coils. Due to the work hardening caused by continuous cold deformation, the strength and hardness of the cold-rolled hard coils increase, and the toughness and plasticity indexes decrease. Cold rolling has a fast forming speed, high output, and does not damage the coating, and can be made into various cross-sectional forms to meet the needs of use conditions. Cold rolling can cause large plastic deformation of steel, thereby increasing the yield point of the steel.

[0003] In the traditional technology, during the production of each finished product unit in the cold rolling treatment line, it is necessary to sample the tail, middle, and head of each coil. The operator moves the sample away from the production line, manually pastes a label, and then separately places it in the sample rack and backup sample rack near the unit. When producing thick or wide strip coils, the sample is heavy, the labor intensity of the operator is very high and the efficiency is low, and there is also the problem of mislabeling the sample. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model proposes the following technical solutions:

[0005] In a first aspect, an embodiment of the utility model provides a cold-rolled sample sampling system, including: a robot, an automatic material receiving device, a sorting table, an industrial label printer, a sample placement rack, and a backup sample placement rack arranged around the robot. The automatic material receiving device is used to receive the sample and transport the sample to a position close to the robot. The industrial label printer is used to print sample labels. The robot is used to grab and place the sample on the sorting table and attach the sample label to the sample. The sample placement rack and the backup sample placement rack are respectively used to place the labeled test samples and backup samples.

[0006] In a possible implementation manner, the automatic material receiving device includes: a roller path, one end of the roller path is arranged on one side of the cold rolling treatment line, and the other end is close to the robot; a material receiving trolley is arranged on the roller path, the top of the material receiving trolley is a sample receiving hopper, and the bottom plate of the sample receiving hopper is movably arranged. The material receiving trolley starts to wait on one side of the cold rolling treatment line. When the sample falls into the receiving hopper, the material receiving trolley runs along the roller path towards the robot until it reaches the specified position and sends a signal of being in place to the robot.

[0007] In a possible implementation, a cylinder is provided at the bottom of the base plate. The movable end of the cylinder is fixedly connected to the bottom of the base plate, and the control end of the cylinder is fixedly arranged on the sample receiving trolley. The first side of the base plate is rotatably connected to the receiving hopper, and the second side and both ends of the base plate are movably arranged. A first bull's eye and a first sample sensor are provided on the base plate. When the sample receiving trolley is not working, the base plate is in a horizontal state. When it is necessary for the sample receiving trolley to receive a sample, the base plate is tilted by controlling the cylinder. In this way, when the sample falls into the hopper, it will slide to one side of the hopper, which is convenient for the robot to grasp later.

[0008] In a possible implementation, a plurality of the first bull's eyes and the first sample sensors are provided. The plurality of first bull's eyes are evenly arranged on the base plate, and the plurality of first sample sensors are arranged in a row on the first side of the base plate. The multiple first bull's eyes provided on the base plate ensure that the sample falling into the hopper can slide smoothly. The first sample sensor arranged on the first side of the base plate detects the real-time position of the sample and transmits it to the robot, further ensuring that the robot can successfully grasp the sample.

[0009] In a possible implementation, the sorting table includes a bracket and a tabletop arranged on the bracket. The tabletop is inclined. A plurality of second bull's eyes are evenly arranged on the tabletop. A first baffle and a second baffle are respectively arranged at the bottom edge and one side surface of the tabletop. A bearing group is arranged on the first baffle. The connection between the first baffle and the second baffle is the lowest end of the tabletop, and a second sample sensor is arranged at the lowest end of the tabletop. When the sample is placed on the tabletop by the robot, under the action of the second bull's eyes and the bearing group, the sample can slide to the corner at the lowest end of the tabletop. At the same time, the second sample sensor arranged at the corner detects whether the sample is in place.

[0010] In a possible implementation, both the first sample sensor and the second sample sensor are photoelectric sensors.

[0011] In a possible implementation, an AGV trolley is further included. The AGV trolley is used to transport the sample preparation rack to the sample preparation room. During shift change, the AGV trolley transports the sample preparation rack of the previous shift to a fixed position in the sample preparation room, and at the same time transports the sample preparation rack of the current shift from the sample preparation room to the working position.

[0012] In the embodiment of the present utility model, from the transportation of the sample to the sampling, sorting, labeling, a robot is introduced for processing, realizing the automation of the cold rolling sample sampling process, and solving the problems of large labor intensity and low efficiency of manual handling in traditional cold rolling sampling. During the sample labeling process, according to one sample and one label on the sorting table, the problem of wrong sample labeling is avoided. Description of the Drawings
