[0002] With the continuous progress of technology, industrial automation and intelligent technologies have gradually become hot topics in the manufacturing industry. In the field of metal processing, sheet metal bending and forming is one of the key workpieces. The traditional single-machine operation production method for bending has many inefficiencies. For example, equipment downtime for waiting to switch, waiting for material transfer, and excessive manual intervention are not only inefficient but also difficult to guarantee accuracy. However, with the continuous development of the metal processing industry, the requirements for bending metal sheets are getting higher and higher. By combining the conveying function and automatic bending technology, rapid and accurate bending and conveying of metal sheets can be achieved on the production line, reducing labor costs while improving product quality. The inconsistent placement positions and directions of workpieces on the conveying platform will result in the need for additional adjustment of the workpieces during bending, reducing the conveying efficiency of the conveying platform. If the surface of the workpiece is not treated before bending, it will cause damage to the bending die during the bending process, affecting the bending accuracy.

[0003] Patent document CN104550337B discloses an automatic bending system for elevator hall door panels based on an assembly line. The above patent realizes the automatic bending of elevator hall door panels with different widths, and the size range can be between 400 - 500 for the width of the hall door panel, and it can also be used for bending elevator car walls of this specification, with strong applicability.

[0004] In summary, the above patent uses a bending machine and a workpiece conveying device. The workpiece conveying device includes an input section, a feeding section, and an output section. Conveyor belts are provided on both the input section and the output section. The feeding section includes: a transverse movement platform, slidably fitted on the frame for driving the workpiece closer to or away from the bending machine; a pusher mechanism, installed on the transverse movement platform for pushing the workpiece on the transverse movement platform to the processing position; a clamping mechanism, fixed on the transverse movement platform for clamping the workpiece so that the workpiece follows the transverse movement platform away from the bending machine; a bending follow-up mechanism for following and supporting the bent workpiece to fall onto the transverse movement platform to complete the bending of elevator car walls of different specifications. However, there is still some room for optimization in the treatment of workpieces before bending.

Infrared rays are emitted to the mold 31 through the infrared emitter. By calculating the time when the infrared receiver receives the reflected infrared rays, the distance between the surface of the mold 31 and the infrared sensor 27 is calculated through the formula s = v * t / 2, where s is the distance between the infrared sensor 27 and the mold 31, v is the propagation speed of infrared rays in the air, and t is the time from the emission of the infrared rays to the reception of the reflected infrared rays by the infrared receiver. By comparing the distance between the infrared sensor 27 and the mold 31 when the mold 31 is intact, it is determined whether the mold 31 is worn. When the workpiece reaches the bending assembly position, the workpiece is fixed by the clamping plate 32. The part of the workpiece that needs to be bent is moved below the mold 31 through the moving unit 33. The slider 23 is connected to the mold 31 through the fixator 26.

The detection assembly 21 includes: an infrared sensor 27, a stress sensor 28, and a rotating unit 29. The infrared sensor 27 and the stress sensor 28 are connected to the controller 8 through signal lines. The infrared sensor 27 is connected to the bending motor 30 through the rotating unit 29; On the upper side of the outer wall of the conveyor belt 1, a rotating unit 29 is installed. On the upper side of the outer wall of the rotating unit 29, an infrared sensor 27 is installed. On the right side of the outer wall of the infrared sensor 27, a stress sensor 28 is installed; The rotating unit 29 includes: a base 49, a universal joint 50, a rotating shaft 51, and a power gear 52. The power gear 52 is connected to the bending motor 30 through a connecting shaft; On the upper side of the outer wall of the conveyor belt 1, a base 49 is installed. In the middle of the inner wall of the base 49, a universal joint 50 is installed. In the middle of the inner wall of the universal joint 50, a power gear 52 is installed. In the upper part of the inner wall of the universal joint 50, a rotating shaft 51 is installed; Further, when the workpiece is transported on the conveyor belt 1, the bending motor 30 drives the rotating unit 29 to turn the infrared sensor 27 towards the running direction of the conveyor belt 1, and adjusts the emission angle of the infrared emitter of the infrared sensor 27 to be able to detect the entry of the workpiece into the bending assembly. When the infrared sensor 27 detects the entry of the workpiece into the bending assembly, the orientation of the infrared sensor 27 is kept unchanged. After the workpiece completely enters the bending assembly, the controller 8 controls the rotating unit 29 to turn the infrared sensor 27 towards the position where the workpiece needs to be processed. During the downward movement of the slider 23 driving the mold 31, through the detection of the infrared sensor 27, the accuracy of the processing position of the mold 31 is ensured. After the processing is completed, the stress distribution inside the workpiece is detected by the stress sensor 28. Inside the stress sensor 28, an elastic sensitive element, a resistance strain gauge, and a measuring circuit are provided. After the workpiece is processed, the controller 8 attaches the stress sensor 28 to the surface of the workpiece through the rotating unit 29. After the workpiece is bent, strain is generated inside, causing the elastic sensitive element attached to the surface of the workpiece to deform. The resistance strain gauge attached to the elastic sensitive element deforms accordingly, causing the resistance value of the resistance strain gauge to change. Through the measuring circuit, the change in the resistance value is converted into a change in voltage or current using the bridge principle, and the information is transmitted to the controller 8. If the stress inside the workpiece is too large or unbalanced, the controller 8 controls the moving unit 33 to restore the workpiece to its original position, and the workpiece is conveyed to the preheating assembly 3 through the conveyor belt 1. The controller 8 heats the whole workpiece through the flame sprayer 17 according to the stress distribution inside the workpiece detected by the stress sensor 28. Further heat is applied to the position where the stress inside the workpiece is too large to eliminate the internal stress of the workpiece, realizing the intelligent function of workpiece bending, solving the problems of low processing efficiency and poor processing quality of the finished product, being able to reduce the intervention of manpower during the bending and transportation of the workpiece, improving the accuracy of workpiece bending, increasing the processing efficiency, reducing the labor cost, and improving the economic benefits of the equipment.

When there is dirt on the surfaces of the conveyor belt 1 and the heat insulation plate 7, if the conveyor belt 1 and the heat insulation plate 7 are not cleaned, the controller 8 controls the pressure booster 16 to pressurize the water in the water tank 15 and transport it through the water pipe to the nozzle 14. At the same time, it controls the rotator 12 to drive the brush 11 to rotate, and drives the telescopic shaft 13 through the processing motor 10 so that the brush 11 can clean the conveyor belt 1 and the heat insulation plate 7. During the cleaning process, the conveyor belt 1 is started to ensure that the conveyor belt 1 and the heat insulation plate 7 can be completely cleaned, realizing the function of cleaning the conveyor belt 1 and the heat insulation plate 7, solving the problems of the workpiece shifting during transportation, dirt adhering to the surface of the workpiece, wearing the conveyor belt 1, and damaging the equipment. It can ensure the cleanliness of the conveyor belt 1 and the heat insulation plate 7, prevent the workpiece from running off track and affecting bending, reduce the wear of the dirt on the conveyor belt 1, extend the service life of the conveyor belt 1, and improve the processing efficiency and processing accuracy of the equipment.

[0027] Working principle: Before and after processing the workpiece, the vision sensor 9 collects information on the conveyor belt 1 and the heat insulation plate 7 on the conveyor belt, and compares the collected information with the conveyor belt 1 that meets the processing standards uploaded. When there is dirt on the surfaces of the conveyor belt 1 and the heat insulation plate 7, if the conveyor belt 1 and the heat insulation plate 7 are not cleaned, the controller 8 controls the pressure booster 16 to pressurize the water in the water tank 15 and transport it through the water pipe to the nozzle 14. At the same time, it controls the rotator 12 to drive the brush 11 to rotate, and drives the telescopic shaft 13 through the processing motor 10 so that the brush 11 can clean the conveyor belt 1 and the heat insulation plate 7. During the cleaning process, the conveyor belt 1 is started to ensure that the conveyor belt 1 and the heat insulation plate 7 can be completely cleaned. The infrared sensor 27 is internally provided with an infrared emitter, an infrared receiver, and a processing circuit. Infrared rays are emitted from the infrared emitter to the mold 31, and the distance between the surface of the mold 31 and the infrared sensor 27 is calculated by calculating the time when the infrared receiver receives the reflected infrared rays. Using the formula s = v * t / 2, where s is the distance between the infrared sensor 27 and the mold 31, v is the propagation speed of infrared rays in the air, and t is the time from the emission of the infrared rays to the reception of the reflected infrared rays by the infrared receiver. Whether the mold 31 is worn is judged by comparing the distance between the infrared sensor 27 and the mold 31 when the mold 31 is intact; The visual sensor 9 collects the features of the workpiece and transmits them to the controller 8. The controller 8 compares the received workpiece information features with the workpiece information that conforms to the bending standard uploaded in advance to identify whether the workpiece needs to be processed, including position and surface cleanliness. When the position needs to be adjusted, the controller 8 controls the orientation components on both sides of the conveyor belt 1, and drives the push rod 5 through the processing motor 10 to push the push plate 4 to adjust the position of the workpiece. When there is a large deviation in the angle of the workpiece, the angle of the push plate 4 during the process of pushing the workpiece is adjusted through the rotating shaft 6. When the surface of the workpiece needs to be cleaned, the cleaning module 2 is used to clean the surface of the workpiece. After the cleaning module completes the cleaning of the workpiece, the type of the workpiece is confirmed through the information collected by the visual sensor 9. The controller 8 obtains the temperature and position that need to be adjusted before bending for this type of workpiece from the database. When the workpiece enters the prediction component through the conveyor belt 1, when the workpiece needs to be heated as a whole, the processing motor 10 drives the first pulley 19 to move back and forth on the first slide rail 18, so that the flame sprayer 17 heats the workpiece back and forth. When the processing position and the vicinity of the workpiece need to be heated, the controller 8 controls the processing motor 10 to drive the first pulley 19 to move to the processing position of the workpiece on the first slide rail 18, and the flame sprayer 17 is connected to the fuel tank 20 to heat the processing position and the vicinity of the workpiece. When heating the workpiece, the moisture remaining after cleaning can also be dried; When the workpiece is transported on the conveyor belt 1, the bending motor 30 drives the rotating unit 29 to turn the infrared sensor 27 in the running direction of the conveyor belt 1, and adjusts the infrared emission angle of the infrared sensor 27 so that it can detect the workpiece entering the bending component. When the infrared sensor 27 detects that the workpiece enters the bending component, the orientation of the infrared sensor 27 is kept unchanged. After the workpiece completely enters the bending component, the workpiece is fixed by the clamping plate 32, and the part of the workpiece that needs to be bent is moved under the mold 31 through the moving unit 33. The slider 23 is connected to the mold 31 through the fixator 26. The fixation of the mold 31 is released, and the slider 23 slides up and down on the guide rail 22 to perform bending processing on the part of the workpiece that needs to be bent. After the bending is completed, the slider 23 drives the mold 31 to move up, and the mold 31 is fixed through the fixator 26. At the same time, the connection between the slider 23 and the mold 31 is released, and the infrared sensor 27 is turned to the workpiece through the rotator 12 to detect the bending effect of the mold 31. When the bending effect is not good and needs to be adjusted, the fixation of the stop block 24 is released through the fixator 26, and the slider 23 is connected to the stop block 24. The stop block 24 is moved downward through the slider 23 to finely adjust the workpiece. The controller 8 controls the rotating unit 29 to turn the infrared sensor 27 to the position where the workpiece needs to be processed. During the process of the slider 23 driving the mold 31 and the stop block 24 to move downward, through the detection of the infrared sensor 27, the accuracy of the processing position of the mold 31 is ensured; After the workpiece is processed, the controller 8 attaches the stress sensor 28 to the surface of the workpiece through the rotating unit 29. When the workpiece is bent, strain is generated inside it. The stress distribution information is transmitted to the controller 8 through the stress sensor 28. When the internal stress of the workpiece is too large or unbalanced, the controller 8 controls the moving unit 33 to restore the workpiece to its original position, and the workpiece is conveyed to the preheating assembly 3 through the conveyor belt 1. The controller 8 heats the whole workpiece through the torch 17 according to the internal stress distribution of the workpiece detected by the stress sensor 28, and further heats the position where the internal stress of the workpiece is too large to eliminate the internal stress of the workpiece.
