Description

Technical Field

[0001] The present invention relates to the technical field of electroplating equipment, and in particular to a speed adaptation device, an electroplating drive system and a drive control method. Background Art

[0002] It's a well-known phenomenon that metal surfaces are susceptible to rust and corrosion. This is why metal surface treatment processes have emerged. Surface treatment is the process of forming a coating on a workpiece's surface using various methods, including electroplating, immersion plating, mechanical plating, and chemical plating. Immersion plating involves immersing the workpiece in molten metal to form a metallic coating.

[0003] The electroplating production line's drive structure consists of a receiving drive motor and an intermediate drive motor to drive the plating sheet, allowing the sheet to pass through the plating device for plating. Because the motors are variable frequency gear reduction motors, the speeds of the receiving drive motor and the intermediate drive motor cannot be precisely controlled to achieve complete synchronization. This speed asynchrony can lead to the following problems:

[0004] 1. The electroplating sheet slips relative to the intermediate drive wheel or the pull wheel, causing damage to the electroplating sheet;

[0005] 2. There is a risk of the electroplating sheets being stretched and broken, or stacking up between the two motor sections, resulting in batch scrapping;

[0006] 3. The electroplating device is affected by the asynchronous speed of the two motors, causing other quality problems.

[0007] Therefore, it is necessary to design an electroplating drive system that synchronizes the speeds of the receiving drive motor and the intermediate drive motor. Summary of the Invention

[0008] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a speed adaptation device, an electroplating drive system and a drive control method to solve the problem in the prior art that the speeds of the material receiving drive motor and the intermediate drive motor cannot be synchronized.

[0036] like Figures 1 to 9 As shown, the present invention provides a speed adaptation device, which includes a base 11, a pull-tab wheel 12, a pull-tab wheel mounting frame 13 and a displacement sensor 14. The pull-tab wheel 12 is mounted on the pull-tab wheel mounting frame 13 and can rotate on the pull-tab wheel mounting frame 13. The pull-tab wheel mounting frame 13 is mounted on the base 11 and can slide on the base 11. The pull-tab wheel 12 slides on the base 11 along with the pull-tab wheel mounting frame 13. The displacement sensor 14 is mounted on the base 11 and is used to detect the displacement of the pull-tab wheel mounting frame 13 sliding on the base 11, thereby detecting the displacement of the pull-tab wheel 12 sliding on the base 11.

[0037] In this embodiment, Figure 6 and Figure 7As shown, the pull-tab wheel mounting frame 13 includes a sliding seat 131, a rotating shaft 132, and a push rod connector 133. The rotating shaft 132 is a flanged shaft, and one end of the rotating shaft 132 with a flange is fixed to the sliding seat 131. The two ends of the rotating shaft 132 are respectively connected to the sliding seat 131 and the push rod connector 133. The sliding seat 131 is slidably connected to the base 11. The pull-tab wheel 12 is mounted on the rotating shaft 132, and the push rod connector 133 is connected to the detection end of the displacement sensor 14. Among them, the displacement sensor 14 is preferably an electronic ruler. The displacement sensor 14 includes a push rod 141, one end of which is connected to the push rod connector 133. The sliding of the push rod connector 133 drives the push rod 141 to extend and retract, thereby detecting the displacement of the push rod connector 133. The electronic ruler detects the displacement of the push rod 141 by the change in the resistance within the electronic ruler caused by the sliding of the push rod 141. For a more detailed introduction to the electronic ruler, please refer to the existing technology and will not be repeated here.

[0038] Further, if Figure 2 As shown, the base 11 is provided with a guide shaft 111 and a guide shaft mounting plate 112. There are two guide shaft mounting plates 112. Both ends of the guide shaft 111 are mounted on the base 11 through the guide shaft mounting plates 112. The sliding seat 131 is provided with a mounting hole 131a that cooperates with the guide shaft 111. A linear bearing 131b is provided in the mounting hole 131a. The sliding seat 131 slides along the guide shaft 111 through the linear bearing 131b.

[0039] Furthermore, the base 11 is also provided with an adjustment plate 113, a spring (not shown) and an adjustment bolt 114. The adjustment plate 113 and the spring are both mounted on the guide shaft 111. The two ends of the spring are respectively in conflict with the adjustment plate 113 and the sliding seat 131. The adjustment bolt 114 is connected to the adjustment plate 113 by a thread. One end of the adjustment bolt 114 is in conflict with the guide shaft mounting plate 112 and is used to adjust the position of the adjustment plate 113 on the guide shaft 111, so that the elastic force of the spring can be adjusted by adjusting the bolt 114.

[0040] Furthermore, a spring stopper 131c is provided on the side of the sliding seat 131 facing the spring. Figure 6 ), one end of the spring contacts the spring stopper 131 c, and the other end contacts the adjustment plate 113.

[0041] In this embodiment, the pull-tab wheel 12 is provided with an axial hole 121 that cooperates with the rotating shaft 132. Rotating bearings 122 are provided at both ends of the axial hole 121. Preferably, the rotating bearings 122 are ceramic bearings to prevent corrosion and rust.

[0042] In this embodiment, the speed adaptation device 10 further includes a sensor mounting frame 15, which includes a mounting base 151, a support rod 152, and a sensor mounting plate 153. One end of the support rod 152 is connected to the mounting base 151, and the other end of the support rod 152 is connected to the sensor mounting plate 153. The mounting base 151 is connected to the base 11, and the displacement sensor 14 is mounted on the sensor mounting plate 153. Preferably, the mounting base 151 is fixed to the base 11 via the guide shaft mounting plate 112. Specifically, the mounting base 151 is fixed to the guide shaft mounting plate 112, which is in turn fixed to the base 11. Initially, the pull-wheel mounting frame 13 is located at the end away from the sensor mounting frame 15.

[0043] Furthermore, a fixing plate 142 is provided on the displacement sensor 14 , and the displacement sensor 14 is fixed to the sensor mounting plate 153 through the fixing plate 142 .

[0044] like Figure 1 As shown, the present invention also provides an electroplating drive system, including an intermediate drive wheel 20, a receiving drive wheel 30, an electroplating device 40, a plurality of film-feeding wheels 50 and the speed adaptation device 10 as described above. The intermediate drive wheel 20, the speed adaptation device 10, the electroplating device 40 and the receiving drive wheel 30 are arranged in sequence toward the movement direction of the electroplating sheet 60. The front and rear ends of the intermediate drive wheel 20, the speed adaptation device 10 and the electroplating device 40 are all provided with film-feeding wheels 50. In this embodiment, the number of film-feeding wheels 50 is four, and the axes of the four film-feeding wheels 50 are at the same level. The axes of the intermediate drive wheel 20 and the receiving drive wheel 30 are at the same level, but at different heights from the film-feeding wheels 50.

[0045] Furthermore, the electroplating drive system also includes an intermediate drive motor and a receiving drive motor. The intermediate drive motor is used to drive the intermediate drive wheel 20 to rotate, and the receiving drive motor is used to drive the receiving drive wheel 30 to rotate.

[0046] The present invention also provides a drive control method for controlling the electroplating drive system as described above, the drive control method comprising:

[0047] First, set the zero position of the speed adaptor 10 so that the pull-tab wheel mounting bracket 13 is not located at the extreme ends of the sliding stroke. Figure 1 , that is, the pull-tab wheel mounting frame 13 and the pull-tab wheel 12 are not located at the uppermost and lowermost ends of the guide shaft 111, so that the pull-tab wheel mounting frame 13 and the pull-tab wheel 12 can slide up or down. Of course, the electroplating sheet 60 will have a certain tension at the zero position.

[0048] When the displacement sensor 14 detects that the pull-tab wheel mounting frame 13 moves in a direction away from the electroplating sheet 60, the intermediate drive wheel 20 is controlled to increase its speed until the pull-tab wheel mounting frame 13 moves to the zero position. Specifically, when the speed of the intermediate drive wheel 20 is lower than the speed of the receiving drive wheel 30, the electroplating sheet 60 is subjected to the forward friction of the receiving drive wheel 30, the electroplating sheet 60 is tightened and the tension increases, thereby causing the pull-tab wheel mounting frame 13 and the pull-tab wheel 12 to slide upward (moving in a direction away from the electroplating sheet 60). The displacement sensor 14 detects that the pull-tab wheel mounting frame 13 slides upward and then feeds back the signal to the intermediate drive motor, so that the intermediate drive motor increases the speed of the intermediate drive wheel 20 so that the speed of the intermediate drive wheel 20 remains the same as the speed of the receiving drive wheel 30. Then, the tension of the electroplating sheet 60 is reduced, causing the pull-tab wheel mounting frame 13 and the pull-tab wheel 12 to slide downward and return to the zero position, thereby eliminating the adverse effects caused by the speed difference between the intermediate drive motor and the receiving drive motor.

[0049] When the displacement sensor 14 detects that the pull-tab wheel mounting frame 13 moves toward the side of the electroplating sheet 60, the intermediate drive wheel 20 is controlled to reduce its speed until the pull-tab wheel mounting frame 13 moves to the zero position. Specifically, when the speed of the intermediate drive wheel 20 is lower than the speed of the receiving drive wheel 30, the electroplating sheet 60 is subjected to the forward friction of the intermediate drive wheel 20, the electroplating sheet 60 becomes loose and the tension is reduced, thereby causing the pull-tab wheel mounting frame 13 and the pull-tab wheel 12 to slide downward (move toward the side of the electroplating sheet 60). The displacement sensor 14 detects that the pull-tab wheel mounting frame 13 slides downward and then feeds back the signal to the intermediate drive motor, so that the intermediate drive motor reduces the speed of the intermediate drive wheel 20 so that the speed of the intermediate drive wheel 20 remains the same as the speed of the receiving drive wheel 30. Then, the tension of the electroplating sheet 60 increases, causing the pull-tab wheel mounting frame 13 and the pull-tab wheel 12 to slide upward and return to the zero position, thereby eliminating the adverse effects caused by the speed difference between the intermediate drive motor and the receiving drive motor.
