Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to an automatic tension adjustment device for a vertical continuous electroplating line. Background Technology

[0002] In a vertical continuous electroplating production line, a tension regulating device is a device used to control the tension of the conveying system during the electroplating process. Its core function is to ensure that the workpiece (such as copper foil and steel strip) maintains a stable operating state during the conveying process, and to avoid problems such as uneven plating, workpiece displacement or detachment caused by tension fluctuations. The stability of the tension directly affects the quality of the product and the production efficiency.

[0003] Traditional adjustment methods typically involve adding or removing counterweights on the guide rollers to adjust the tension. This requires workers to repeatedly adjust the tension based on experience, resulting in a slow response time and an inability to respond to changes in working conditions (such as changes in workpiece weight and length) in real time. Furthermore, it cannot meet the real-time requirements of high-speed production lines.

[0004] Therefore, it is necessary to design an automatic tension adjustment device for a vertical continuous electroplating line. Utility Model Content

[0005] To overcome the shortcomings of traditional technologies that rely on manual experience for adjustment and have slow response speed, this utility model provides an automatic tension adjustment device for a vertical continuous electroplating line.

The controller is installed on the left side of the front of the frame. Guide wheels are rotatably connected to both sides of the upper part of the frame. The motor is installed on the rear side of the upper part of the frame, and the output shaft of the motor is connected to one of the guide wheels. A pulley is wound around the front side of the two guide wheels. The first electric guide rail is installed on the rear side of the middle of the frame. A rotating shaft is slidably connected to the first electric guide rail, and the rotating shaft is also slidably connected to the frame.

A vision camera is installed on the lower side of the middle of the frame, and the vision camera is located directly below the adjusting wheel. The controller is electrically connected to the motor, pressure sensor, and vision camera.

[0007] Furthermore, it also includes photoelectric beam sensors and electric grippers. Photoelectric beam sensors are symmetrically installed on the lower part of the front and rear sides of the rotating shaft. The photoelectric beam sensors are flush with the adjusting wheel, and the lasers of the two photoelectric beam sensors reflect each other to form a straight line. A pair of electric grippers are installed on the left and right sides of the upper part of the frame. The electric grippers on the same side are installed one in front and one behind. The controller is electrically connected to the photoelectric beam sensors and electric grippers.

[0008] Furthermore, the damping mechanism includes a damping box, dampers, and elastic elements. The damping box is slidably connected to the lower part of the frame. Multiple dampers are connected between the inside of the damping box and the lower part of the frame. The telescopic ends of the dampers are all connected to the lower part of the frame, and each damper is connected to the lower part of the frame by an elastic element.

[0009] Furthermore, it also includes a second electric guide rail, guide blocks, a correction wheel, and a distance sensor. The second electric guide rail is installed on both the left and right sides of the upper part of the frame. Guide blocks are slidably connected to the second electric guide rail.

[0012] 1. This utility model achieves real-time adjustment of workpiece tension by setting up a combination structure of components such as a first electric guide rail, adjusting wheel and pressure sensor. At the same time, the introduction of vision camera enables the system to have a comprehensive perception of the workpiece's running status, and can identify various abnormal conditions such as slack and breakage, providing a basis for subsequent automatic intervention and improving the level of intelligence of tension control.

Detailed Implementation

Figures 1-5 As shown, the device includes a frame 1, a controller 101, guide wheels 2, a motor 3, a pulley 4, a first electric guide rail 5, an adjusting wheel 6, a rotating shaft 61, a shock absorption mechanism, a pressure sensor 7, and a vision camera 8. The controller 101 is mounted on the front left side of the frame 1. Guide wheels 2 are rotatably connected to both sides of the upper part of the frame 1. The motor 3 is bolted to the rear side of the upper part of the frame 1. The output shaft of the motor 3 is connected to one of the guide wheels 2. A pulley 4 is wound around the front sides of the two guide wheels 2. The frame 1... A first electric guide rail 5 is installed on the rear side of the unit. A rotating shaft 61 is longitudinally slidably connected to the first electric guide rail 5. The rotating shaft 61 is also slidably connected to the frame 1. An adjusting wheel 6 is rotatably connected to the middle of the rotating shaft 61. A shock-absorbing mechanism is provided at the lower part of the frame 1. A pressure sensor 7 is connected between the front side of the rotating shaft 61 and the shock-absorbing mechanism. A vision camera 8 is installed on the lower side of the middle part of the frame 1. The vision camera 8 is located directly below the adjusting wheel 6. The controller 101 is electrically connected to the motor 3, the pressure sensor 7 and the vision camera 8.

[0021] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes photoelectric beam sensors 9 and electric grippers 10. Photoelectric beam sensors 9 are symmetrically installed on the lower front and rear sides of the rotating shaft 61. The photoelectric beam sensors 9 are flush with the adjusting wheel 6, and the lasers of the two photoelectric beam sensors 9 are directed at each other to form a straight line. A pair of electric grippers 10 are installed on the left and right sides of the upper part of the frame 1. The electric grippers 10 on the same side are installed one in front and one behind. The controller 101 is electrically connected to the photoelectric beam sensors 9 and the electric grippers 10.

[0022] like Figure 1 and Figure 4As shown, the damping mechanism includes a damping box 11, a damper 12, and an elastic element 13. The damping box 11 is slidably connected to the lower part of the frame 1. Multiple dampers 12 are connected between the inside of the damping box 11 and the lower part of the frame 1. The telescopic ends of the dampers 12 are all connected to the lower part of the frame 1, and each damper 12 is connected to the lower part of the frame 1 with an elastic element 13, which is a spring.

[0023] like Figure 4 and Figure 5 As shown, it also includes a second electric guide rail 14, a guide block 15, a correction wheel 16, and a distance sensor 17. The second electric guide rail 14 is installed on both the left and right sides of the upper part of the frame 1. The guide block 15 is slidably connected to the second electric guide rail 14. The correction wheel 16 is rotatably connected to the middle of the guide block 15. The distance sensor 17 is installed on the rear side of the upper part of the frame 1. The distance sensor 17 and the second electric guide rail 14 are electrically connected to the controller 101.

[0024] like Figure 1 and Figure 4 As shown, it also includes foot pads 18, which are made of rubber. Multiple foot pads 18 are provided at the bottom of the shock-absorbing box 11 to reduce the transmission of equipment vibration to the ground and ensure the image clarity of the vision camera 8.

[0025] like Figures 1-5 As shown, the surfaces of the guide wheel 2, the adjusting wheel 6, and the straightening wheel 16 are all coated with ceramic, which can reduce the frictional resistance between the workpiece and the guide wheel and extend the life of the wheel body 3.

[0026] When using this equipment, the operator needs to introduce the workpiece to be processed (taking steel strip as an example) from the external conveying system, and pass it sequentially through the left-side straightening wheel 16 and the left-side guide wheel 2. Then, the workpiece needs to pass around the lower adjusting wheel 6, and finally pass through the right-side guide wheel 2 and straightening wheel 16 to complete the entire path arrangement. Subsequently, the operator needs to control the motor 3 through the controller 101. The motor 3 drives the guide wheel 2 on one side to rotate, and the pulley 4 enables the guide wheels 2 on both sides to rotate synchronously, ensuring that the workpiece is conveyed forward at a uniform speed and smoothly. During this process, the vision camera 8 continuously captures images of the workpiece surface and analyzes them using image processing algorithms to check for looseness, breakage, or other abnormalities. If a gap is detected between the workpiece surface and the adjusting wheel 6, accompanied by obvious up-and-down shaking, it indicates that the current tension is insufficient. At this time, the vision camera 8 will feed back the detection results to the controller 101. The controller 101 will drive the first electric guide rail 5 to operate based on the received data, so that the rotating shaft 61 drives the adjusting wheel 6 to move downward, increasing the pressure on the workpiece and thus increasing the tension value. Conversely, when the workpiece surface shows signs of excessive deformation, the controller 101 will instruct the adjusting wheel 6 to move upward, appropriately release the tension, and ensure that the workpiece is always in the optimal tension state.

[0027] Meanwhile, under normal operating conditions, the laser beam emitted by the photoelectric photoelectric sensors 9 installed on both sides of the rotating shaft 61 is blocked by the workpiece. Once a tape breakage event occurs, the beam is no longer blocked, and the photoelectric photoelectric sensors 9 can quickly identify and send a signal. At the same time, the pressure value monitored by the pressure sensor 7 will also drop significantly. When the above two conditions are met simultaneously, the controller 101 determines that there is a tape breakage fault and immediately triggers the response mechanism: the pair of electric grippers 1 on the upper left and right sides of the control frame 1 quickly close, clamping the two ends of the broken tape to prevent it from continuing to slip or bounce. At the same time, the motor 3 stops running to avoid splashing of toxic electroplating solutions (such as cyanide plating solutions) due to the broken tape swinging, ensuring operational safety.

[0028] In terms of lateral positioning, the ranging sensor 17 monitors the edge position of the workpiece in real time to determine whether any deviation has occurred. Once the workpiece is found to deviate from the preset path, the controller 101 calculates the required adjustment angle based on the deviation and instructs the second electric guide rail 14 to drive the guide block 15 to slide along the track, thereby adjusting the position of the correction wheel 16 to restore the workpiece to a centered state, thus realizing the dynamic correction function. In addition, considering the vibration that may be generated during the transmission of the workpiece, a shock absorption mechanism is configured at the bottom of the frame 1. This mechanism includes a shock absorption box 11, multiple dampers 12, and elastic elements 13 (springs), which can effectively absorb vibration energy, reduce the vibration of the whole machine, and reduce the transmission impact to the ground. This design not only improves the stability of the system but also ensures the clarity of the image captured by the vision camera 8, avoiding misjudgments caused by vibration.
