Abstract
Description
Technical Field
[0001] This utility model relates to a steel end nameplate welding mechanism system, belonging to the technical field of machinery. Background Technology
[0002] The steel is sold in bundles, and a nameplate is welded to the end of each bundle. The nameplate records the basic information of the bundle of steel, such as the steel type and weight.
[0003] Currently, steel nameplate welding in the market is mainly done manually, resulting in repetitive and monotonous work. A robotic nameplate welding system can automate the welding process by enabling real-time transmission of printed information, real-time laser marking, automatic nail and nameplate removal, and visual positioning and recognition. Through project implementation, the level of automation will be improved, the working environment will be enhanced, labor intensity will be reduced, and personnel allocation will be optimized.
[0004] Currently, conventionally designed robotic nameplate welding systems require at least forty seconds to complete the entire process, from receiving and engraving nameplate information, automatically sorting weld nails, monitoring the three-dimensional coordinates of the steel end face, and automatically welding the nameplate. This cannot meet the production pace of large-circle short-branch steel bundles and severely restricts production efficiency. Summary of the Invention
[0005] To address the aforementioned problems, this utility model discloses a steel end nameplate welding mechanism system, the specific technical solution of which is as follows: A steel end nameplate welding mechanism system, wherein a first conveyor belt group and a second conveyor belt group are set sequentially from upstream to downstream according to the direction of steel conveying. After the steel is bundled, it is placed horizontally on the first conveyor belt group in bundles and transferred from the first conveyor belt group to the second conveyor belt group. A weighing mechanism is installed below the first section of the conveyor belt assembly, and a nameplate welding robot is installed on the outer side of one side of the first section of the conveyor belt assembly, with the nameplate welding robot located downstream of the weighing mechanism. The first section of the conveyor belt is equipped with a first photoelectric sensor at the position of the nameplate welding robot, a second photoelectric sensor is equipped at the upstream end of the second section of the conveyor belt, and a third photoelectric sensor is equipped at the downstream end of the second section of the conveyor belt. A baffle is non-contactly installed at the downstream end of the second section of the conveyor belt, and the baffle is located in the lateral direction of the downstream end to prevent the steel on the second section of the conveyor belt from falling. The first photoelectric sensor, the second photoelectric sensor, and the third photoelectric sensor are all connected to the PLC controller.
[0006] Furthermore, the first and second conveyor belt groups partially overlap. The distance from the steel placement station to the weighing station and the distance from the weighing station to the welding station are the same. The switches of the first and second conveyor belt groups are synchronized and linked, turning on and off simultaneously.
[0007] Furthermore, multiple conveyor rollers are dispersedly arranged on the upstream side of the first section of the conveyor belt group. All the conveyor rollers are arranged in a straight line to form a roller track. The roller track coincides with the upstream end of the first section of the conveyor belt. The roller track is used to move the bundled steel to the upstream end of the first section of the conveyor belt group. The roller track is perpendicular to the conveying direction of the first section of the chain group, and a positioning baffle is provided at the downstream end of the roller track. The upstream and downstream reversing wheels of the first section of the conveyor belt group are equipped with lifting mechanisms. Furthermore, the first conveyor belt group and the second conveyor belt group each have more than two conveyor belts.
[0008] Furthermore, both the first and second conveyor belt groups are made of chain conveyor belts.
[0009] Furthermore, the first photoelectric sensor is located below the first section of the conveyor belt assembly, and the second and third photoelectric sensors are located below the second section of the conveyor belt assembly, both sensing upwards whether there is steel on the corresponding conveyor belt.
[0010] The beneficial effects of this utility model are: This invention separates the weighing and nameplate welding operations, allowing both to be performed simultaneously, thus shortening the process time and reducing waiting time. The downstream two-section chain is used to temporarily hold the steel after the nameplate welding. Second and third photoelectric sensors monitor whether the chain is full. When both sensors detect the presence of steel, it indicates the chain is full, and the next process is notified to remove the steel from the chain. Attached Figure Description

The list of reference numerals is as follows: 1—first conveyor belt group, 2—transmitter roller, 3—steel, 4—weighing mechanism, 5—second conveyor belt group, 6—baffle, 7—third photoelectric sensor, 8—second photoelectric sensor, 9—first photoelectric sensor, 10—nameplate welding robot. Detailed Implementation
[0012] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0013] Combined with appendix Figure 1As can be seen, steel material 3 represents a bundle of steel, as illustrated in the simplified diagram. The first conveyor belt group 1 and the second conveyor belt group 5 are also simplified diagrams. Each conveyor belt has a conveyor wheel at both ends, with a motor on one of the wheels. The conveyor belt is taut and fitted onto the two wheels. During transport, the motor drives the wheels to rotate, and the conveyor belt moves around them. This steel end nameplate welding mechanism system centralizes traditional weighing and nameplate welding operations into one operation. All actions must be completed sequentially, resulting in waiting periods between actions. The main actions here are weighing, printing nameplates, and welding nameplates. If weighing, printing, and welding were performed in the same process, it would take approximately 40 seconds to complete all three tasks. During the execution of any one action, the other two actions wait. This invention separates these three actions. When the steel arrives at the weighing position, it is weighed. After the weighing result is obtained, the nameplate is printed. After the robot finishes affixing the nameplate to the steel at the welding position, the steel moves to the nameplate welding position. The nameplate has already been printed, and the robot directly picks up the nameplate for welding. At this time, the next bundle of steel is being weighed at the weighing position. After weighing, the nameplate is printed immediately. In this way, there is no waiting time between the three tasks. The time to complete the nameplate welding of one bundle of steel is the time for one complete cycle of steel processing. The weighing and nameplate printing times are both completed during the welding time of the previous bundle of steel, and weighing and nameplate printing no longer occupy the time of this process.
[0014] Following the direction of steel material 3's transport, a first conveyor belt group 1 and a second conveyor belt group 5 are sequentially arranged from upstream to downstream. A weighing mechanism 4 is located below the first conveyor belt group 1, and a nameplate welding robot 10 is located on the outer side of the first conveyor belt group 1, downstream of the weighing mechanism 4. Steel material 3 comes from upstream, is first weighed, then a nameplate is printed, and then it reaches the nameplate welding point, where the nameplate welding robot 10 welds the nameplate to the end of the steel material 3. After the steel material 3 is bundled, it is placed horizontally on the first conveyor belt group 1 in bundles. The distance from the workstation for placing steel material 3 in the first conveyor belt group 1 to the weighing workstation is the same as the distance from the weighing workstation to the welding workstation. The switches of the first conveyor belt group 1 and the second conveyor belt group 5 are synchronously linked, turning on and off simultaneously. When steel material 3 arrives at the weighing station, both the first conveyor belt group 1 and the second conveyor belt group 5 stop. A new bundle of steel material 3 is placed at the upstream loading station of the first conveyor belt group 1. The weighing station weighs the material and transmits the weight information to the printing system, which prints a nameplate. At the nameplate welding station, a welding robot welds the nameplate. After welding is completed, the welding robot returns to its position, triggering the completion of the process. Simultaneously, the first conveyor belt group 1 and the second conveyor belt group 5 are activated. The first conveyor belt group 1 transports steel material 3 from the loading station to the weighing station, then from the weighing station to the nameplate welding station, and finally from the nameplate welding station to the second conveyor belt group 5. This achieves coordinated operation between the corresponding stations. The cycle repeats continuously.
[0015] A first photoelectric sensor 9 is installed at the position of the nameplate welding robot 10 on the first conveyor belt group 1. The function of the first photoelectric sensor 9 is to detect the presence of steel material 3 at the welding station when welding nameplates, preventing empty welding when there is no steel material 3. A second photoelectric sensor 8 is installed at the upstream end of the second conveyor belt group 5 to detect whether there is steel material 3 upstream of the second conveyor belt group 5, and a third photoelectric sensor 7 is installed at the downstream end of the second conveyor belt group 5 to detect whether there is steel material 3 downstream of the second conveyor belt group 5. The second photoelectric sensor 8 and the third photoelectric sensor 7 work together. When both sides of the second conveyor belt group 5 are detected simultaneously, it indicates that the steel material 3 on the second conveyor belt group 5 needs to be removed. A non-contact baffle 6 is installed at the downstream end of the second conveyor belt group 5. The baffle 6 is located in the lateral direction at the downstream end to prevent the steel material 3 on the second conveyor belt group 5 from falling. The first photoelectric sensor 9, the second photoelectric sensor 8, and the third photoelectric sensor 7 all sense upwards to detect whether there is steel material 3 on the corresponding conveyor belt. The first photoelectric sensor 9, the second photoelectric sensor 8, and the third photoelectric sensor 7 are all connected to the PLC controller. The function of the first photoelectric sensor 9 is to monitor whether there is steel 3 at the welding nameplate position. In a complete process, when it detects that there is no steel 3 at the welding nameplate station initially, and then steel 3 appears, it indicates that steel 3 has just been conveyed from upstream. The first conveyor belt group 1 needs to be stopped, allowing steel 3 to remain at the welding nameplate station for the robot to weld the nameplate. After the robot finishes welding the nameplate, it returns to its original position, triggering a positioning signal. The PLC control system then sends a signal to the first conveyor belt group 1 and the second conveyor belt group 5. The first conveyor belt group 1 and the second conveyor belt group 5 are then started to rotate synchronously, conveying the steel 3 with the welded nameplate to the second conveyor belt group 5. After the steel 3 at the weighing position is conveyed to the welding station, the conveying stops. This cycle repeats continuously.
[0016] The following describes how this patented technology transfers bundled steel bars to the upstream end of the first conveyor belt assembly 1 for loading. Multiple conveyor rollers 2 are installed on the upstream side of the first conveyor belt assembly, forming a roller track. The conveyor rollers 2 have a certain width, and the bundled steel bars are placed on their surfaces and moved horizontally via the roller track. The direction of this horizontal movement is perpendicular to the direction of movement of the first conveyor belt assembly. The conveyor rollers 2 are used to move the bundled steel bars to the upstream end of the first conveyor belt assembly, and a stop plate is installed at the downstream end of the roller track. When the bundled steel bars are stopped by the stop plate, the surface of the bundled steel bars is in place. At this time, the first conveyor belt assembly rises, lifting the bundled steel bars, which are then conveyed horizontally towards the weighing mechanism on the first conveyor belt.
[0017] To ensure that the steel bundles do not contact the first conveyor belt assembly during their translation, and that the first conveyor belt assembly can smoothly move the steel bundles away once they are in position, lifting mechanisms are installed on both the upstream and downstream reversing wheels of the first conveyor belt assembly. When there are steel bundles in the roller conveyor, the first conveyor belt assembly lowers to avoid contact with them. Once the steel bundles are in position, the first conveyor belt assembly rises to lift them. The first conveyor belt assembly can then proceed with or pause based on commands triggered by the downstream welding nameplate robot.
[0018] To reduce the weight on each conveyor belt, the first conveyor belt group 1 and the second conveyor belt group 5 each have more than two conveyor belts, each connected to a conveyor motor. In practical applications, three or four conveyor belts can be used side by side to move the steel material 3 at different locations.
[0019] In practical applications, both the first conveyor belt group 1 and the second conveyor belt group 5 are made of chain conveyor belts. Chain conveyor belts are relatively common and have good abrasion resistance.
[0020] The welding nameplate robot and weighing mechanism 4 involved in this invention are existing technologies. The improvement of this patent lies in the design of a complete welding and conveying system, which allows for coordination between various processes and shortens the time required for a complete cycle of welding the nameplate. This improves work efficiency.
