Description

Technical Field

[0001] The invention belongs to the technical field of foil production machines, in particular to a cathode roller transmission speed stabilizing device for a thin copper foil production machine. Background Art

[0002] The thin copper foil machine is a device specially used to produce thin copper foil. It is widely used in new energy, electronics, communications and other fields. The working principle of the thin copper foil machine is based on the electrolytic deposition process of electrolytic copper foil. It uses copper sulfate as the electrolyte. Under the action of direct current, copper ions are deposited on the surface of the cathode roller to form copper foil. The foil machine is mainly composed of an anode tank, a cathode roller drive device, an electrolyte circulation system, etc. When the electrolyte enters the anode tank, an electric field is formed. Under the action of the electric field, copper ions migrate and deposit to the surface of the cathode roller to form copper foil. The thickness of the copper foil is regulated by multiple factors such as current density, cathode roller speed, electrolyte concentration and temperature. Since the copper foil is very thin, when adjusting the thickness of the copper foil, the adjustment range cannot be too large and needs to be increased slowly, otherwise stress concentration is more likely to occur in areas with uneven thickness, which will lead to foil breakage.

[0003] When the existing foil production machine technology adjusts the thickness of the copper foil by adjusting the speed of the cathode roller, the quality of the copper foil is easily affected by the speed of the cathode roller. When the speed of the cathode roller fluctuates, it is easy to cause wrinkles on the surface of the copper foil, or even cause the foil to break, thereby reducing the quality of the produced copper foil. At the same time, most of the existing speed regulation methods adjust the speed of the cathode roller by adjusting the motor current. In order to avoid large changes in the motor speed causing the copper foil to break, the amplitude of each adjustment is small, resulting in multiple adjustments required to make the cathode roller reach the required speed, and the adjustment efficiency is low.

[0019] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Example

[0020] like Figure 1-5As shown, the present invention provides a cathode roller transmission speed stabilizing device for a thin copper foil production machine, comprising a transmission box 1, a transmission shaft 2 for driving the cathode roller to rotate is installed inside the transmission box 1, wherein a speed stabilizing mechanism 3, a reset mechanism 4, a speed reduction mechanism 5 and a brake mechanism 6 are also installed inside the transmission box 1; The speed stabilizing mechanism 3 includes a speed stabilizing sleeve 31 installed inside the transmission case 1, a spiral guide groove 32 is provided on the surface of the speed stabilizing sleeve 31, a spline shaft 33 is installed inside the speed stabilizing sleeve 31, a spline sleeve 34 is sleeved outside the spline shaft 33, a speed stabilizing pin 35 is arranged outside the spline sleeve 34, and the speed stabilizing pin 35 passes through the inside of the spiral guide groove 32 and goes out of the speed stabilizing sleeve 31, and a flywheel 36 is fixedly arranged outside one end of the speed stabilizing sleeve 31; The reset mechanism 4 includes a fixed frame 41 arranged on one side of the speed stabilizing sleeve 31 and a reset ring 42 sleeved on the outside of the speed stabilizing sleeve 31, the reset ring 42 is fixedly connected to the speed stabilizing pin 35, a slide groove 43 is provided on the side of the fixed frame 41 facing the speed stabilizing sleeve 31, a slider 44 is slidably installed in the slide groove 43, the reset mechanism 4 also includes a reset seat 45 installed on the reset ring 42, and the reset seat 45 is fixedly connected to the slider 44, and two springs 46 are symmetrically installed on both sides of the slider 44 inside the slide groove 43.

[0021] The speed reduction mechanism 5 includes a gear 1 51 sleeved on the surface of the speed stabilizing sleeve 31 and a gear 2 52 fixedly arranged on the outer side of the transmission shaft 2 , and the gear 1 51 and the gear 2 52 are meshed and connected.

[0022] The speed-stabilizing sleeve 31 and the transmission box 1 , the transmission shaft 2 and the transmission box 1 , and the speed-stabilizing sleeve 31 and the spline shaft 33 are all rotatably connected via bearings.

[0023] A servo motor 11 is fixedly mounted on an outer wall of one side of the transmission box 1 , and an output end of the servo motor 11 is connected to the spline shaft 33 via a coupling.

[0024] The brake mechanism 6 includes an electric push rod 61 fixedly installed on the inner wall of the transmission box 1 and close to the flywheel 36. A movable block 62 is installed at the output end of the electric push rod 61, and the movable block 62 is slidably connected to the inner wall of the transmission box 1. An arc groove 63 is provided on the side of the movable block 62 facing the flywheel 36, and a brake pad 64 is provided on the inner wall of the arc groove 63.

[0025] The diameter of the speed stabilizing pin 35 is equal to the width of the spiral guide groove 32 .

[0026] like Figure 1-5As shown, when adjusting the thickness of the thin copper foil, the servo motor 11 is started to drive the spline shaft 33 to rotate, and drives the spline sleeve 34 to rotate. The speed-stabilizing pin 35 on the spline sleeve 34 pushes the speed-stabilizing sleeve 31 to rotate through the spiral guide groove 32, drives the gear 1 51 on the speed-stabilizing sleeve 31 to rotate, and then drives the transmission shaft 2 to rotate through the gear 2 52, so as to drive the cathode roller to rotate. The number of teeth of the gear 1 51 is less than that of the gear 2 52, so as to reduce the rotation speed of the servo motor 11 so that the rotation speed of the servo motor 11 adapts to the rotation speed of the cathode roller; then gradually increase or decrease the rotation speed of the servo motor 11 so that the rotation speed of the cathode roller increases or decreases, so as to adjust the thickness of the thin copper foil until the predetermined thickness is reached.

[0027] When the speed of the servo motor 11 driving shaft is stable, the rotation of the spline shaft 33 drives the speed stabilizing sleeve 31 and the flywheel 36 on the speed stabilizing sleeve 31 to rotate synchronously, and the position of the speed stabilizing pin 35 on the spiral guide groove 32 remains unchanged. When the speed of the servo motor 11 driving shaft fluctuates, the speed of the spline shaft 33 changes. At this time, the speed stabilizing sleeve 31 can maintain the original speed due to the inertia of the flywheel 36, so that the speed stabilizing sleeve 31 has a speed difference relative to the spline shaft 33 and the spline sleeve 34. When the speed of the speed stabilizing sleeve 31 is greater than the speed of the spline sleeve 34, the speed stabilizing pin 35 on the spline sleeve 34 is pushed by the spiral guide groove 32 on the speed stabilizing sleeve 31 and moves in one direction of the spiral guide groove 32. Because the reset ring 42 is connected to the speed stabilizing pin 35, the reset seat 45 is connected to the slider 44, and the reset seat 45 is installed on the reset ring 42, the slider 44 moves along one direction of the slide groove 43 and compresses the spring 1 46. When the servo motor When the speed of the driving shaft of 11 is stable, the elastic force of the compression spring 46 pushes the stabilizing pin 35 back to the initial position until the speeds of the spline shaft 33 and the stabilizing sleeve 31 are restored to synchronization, thereby stabilizing the speed of the stabilizing sleeve 31; when the speed of the stabilizing sleeve 31 is less than the speed of the spline sleeve 34, the stabilizing pin 35 on the spline sleeve 34 is blocked by the spiral guide groove 32 on the stabilizing sleeve 31 and moves along the other direction of the spiral guide groove 32, thereby causing the slider 44 to move along the other direction of the slide groove 43, and when the speed of the driving shaft of the servo motor 11 is stable, the stabilizing pin 35 is returned to the initial position by compressing the spring 46; when the speed of the driving shaft of the servo motor 11 fluctuates, the set speed is maintained through the stabilizing sleeve 31, thereby ensuring that the speed of the stabilizing sleeve 31 transmitted to the transmission shaft 2 through the reduction mechanism 5 is more stable, reducing the influence of the speed fluctuation of the servo motor 11, thereby improving the accuracy of speed regulation, and reducing the phenomenon of wrinkles in the copper foil.

[0028] At the same time, when the speed-stabilizing sleeve 31 rotates synchronously, the flywheel 36 has a large rotational inertia. When the speed of the spline shaft 33 increases, the flywheel 36 can absorb excess energy and store it. When the speed of the spline shaft 33 decreases, the flywheel 36 releases the stored energy to make up for the energy shortage, thereby reducing the amplitude of the speed fluctuation of the speed-stabilizing sleeve 31 and making the speed transmitted to the cathode roller by the servo motor 11 more stable.

[0029] It should be noted that after the speed-stabilizing sleeve 31 starts to rotate, the torque of the speed-stabilizing sleeve 31 continues to decrease in order to overcome the inertia of the flywheel 36. When the flywheel 36 reaches a stable stage, the torque of the speed-stabilizing sleeve 31 tends to be balanced with the impedance torque of the spline shaft 33, so that the torque of the speed-stabilizing sleeve 31 increases and maintains a stable speed; when the output torque of the servo motor 11, that is, the torque of the spline shaft 33 changes, the torque of the flywheel 36 does not change at this time. In order to maintain a stable speed, the torque of the flywheel 36 will change accordingly to balance the changed impedance torque, thereby maintaining the stability of the entire system.

[0030] like Figure 2-3 As shown, when the servo motor 11 is turned off, the electric push rod 61 is started synchronously to push the movable block 62 to move toward the flywheel 36, so that the brake pad 64 in the arc groove 63 of the movable block 62 fits with the flywheel 36, and the flywheel 36 is stopped to prevent the flywheel 36 from continuing to rotate due to inertia, causing the transmission shaft 2 to continue to rotate and affecting the speed regulation. Example

[0031] Two through-limiting grooves 47 are symmetrically provided on the inner wall of one side of the slide groove 43 . Limiting blocks 48 are installed between the two springs 46 and the slider 44 of the slide groove 43 , and the two limiting blocks 48 are slidably connected with the two limiting grooves 47 respectively.

[0032] The two limit blocks 48 are pushed toward the slider 44 by two springs 46, so that the slider 44 is in the center position, ensuring that the speed stabilizing pin 35 returns to the initial position when the rotation speed of the spline shaft 33 and the speed stabilizing sleeve 31 is stable.

[0033] The brake mechanism 6 also includes a buffer mechanism 65 arranged between the movable block 62 and the output end of the electric push rod 61. The buffer mechanism 65 includes a connecting plate 651 fixedly connected to the output end of the electric push rod 61 and a guide rod 652 arranged on the side of the movable block 62 away from the flywheel 36. The guide rod 652 passes through the connecting plate 651, and one end of the guide rod 652 is connected to a baffle 653. A spring 654 is sleeved on the outer side of the guide rod 652 between the connecting plate 651 and the movable block 62.

[0034] like Figure 1-2As shown, when the electric push rod 61 is extended, it pushes the connecting plate 651 to compress the spring 2 654, and pushes the movable block 62 through the spring 2 654, so that the brake pad 64 brakes the flywheel 36, and then the brake pad 64 can fully contact with the flywheel 36, so that the friction force of the brake pad 64 on the flywheel 36 increases from small to large, thereby achieving braking.

[0035] The diameter of the speed stabilizing pin 35 is smaller than the width of the spiral guide groove 32. A ball 37 is embedded on the outer side of the speed stabilizing pin 35, and the ball 37 is against the inner wall of the spiral guide groove 32. The movement of the speed stabilizing pin 35 is achieved through the ball 37, which reduces the friction between the speed stabilizing pin 35 and the spiral guide groove 32, and further improves the accuracy of the speed stabilizing mechanism 3 in achieving speed stabilization.

[0036] A second ball 49 is embedded in the reset holder 45 , and the second ball 49 is slidably connected to the reset ring 42 through the slots 410 provided on both sides of the reset ring 42 , so that the reset ring 42 can slide in the reset holder 45 through the second ball 49 , while reducing the friction between the reset ring 42 and the reset holder 45 .

[0037] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
