Technical Field

[0001] The utility model relates to the technical field of production and processing of conductive films, and more specifically to a roller leveling structure and electroplating equipment. Background Art

[0002] As one of the key components of lithium batteries, the conductive film collects the current generated by the active materials in the battery and forms a current that can be output. The current collector deposits a metal layer of a certain thickness on the polymer base film support layer through thin film electroplating equipment to increase the energy density of the battery.

[0003] In thin film production and processing equipment such as thin film electroplating equipment, the film is transported by a roller system. The parallelism of the roller system will affect the flatness of the film surface, and a slight tilt of the roller system will also cause the film to wrinkle. Therefore, in order to ensure the flatness of the film surface, there are higher requirements for the parallelism of the roller system.

[0004] The existing method for adjusting the parallelism of the roller system is to manually adjust the two ends of the roller to the same height so that each roller is horizontal, thereby ensuring the parallelism of the roller system. However, this adjustment method has limited manual adjustment accuracy and is time-consuming and labor-intensive.

[0005] The above shortcomings need to be improved. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] like Figures 1 to 3 As shown, a roller leveling structure described in one embodiment of the utility model includes an active adjustment mechanism 1 and a passive adjustment mechanism 2 arranged at both ends of a roller 3, the active adjustment mechanism 1 is used to detect and adjust the pressure at both ends of the roller 3 to make the roller 3 level, and the passive adjustment mechanism 2 adaptively adjusts the pressure at both ends of the roller 3 to make the roller 3 level.

[0029] When the present embodiment is working, when the roller 3 is in a horizontal state, the two ends of the roller 3 are at the same height, and the pressures at the two ends of the roller 3 are the same. At this time, the active adjustment mechanism 1 can detect that the pressures at the two ends of the roller 3 are the same, and the active adjustment mechanism 1 does not adjust the height of the two ends of the roller 3. At the same time, the passive adjustment mechanism does not work, and the roller 3 is kept horizontal. When the roller 3 is in an inclined state, that is, one end of the roller 3 is higher and the other end is lower, the pressures at the two ends of the roller 3 are also different, the pressure at the higher end is smaller, and the pressure at the lower end is larger. At this time, the active adjustment mechanism 1 can detect the pressure difference at the two ends of the roller 3, and the active adjustment mechanism 1 adjusts the height of the two ends of the roller 3 until the pressures at the two ends of the roller 3 are equal. When adjusting the height, only the higher end can be lowered to make it level with the other end, so that the roller 3 is level. Or the lower end can be raised to make it equal to the other end, so that the roller 3 is level. Or the higher end can be lowered and the lower end can be raised at the same time, so that the roller 3 is level. Within the travel range of the active adjustment mechanism 1, the adjustment is generally performed by moving both ends simultaneously, so that the adjustment distance at both ends is small and the adjustment efficiency is fast. During the adjustment process of the active adjustment mechanism 1, the passive adjustment mechanism 2 performs adaptive adjustment in real time through deformation. The deformation change of the passive adjustment mechanism 2 is negatively correlated with the pressure. When the pressure is large, the support force is large and the deformation change is small. When the pressure is small, the support force is small and the deformation change is large, thereby fine-tuning the height of the end of the roller 3 to make the two ends of the roller 3 level. When the inclination angle of the roller 3 is small, the roller 3 can be kept level through the passive adjustment mechanism 2, and when the roller 3 rotates, dynamic adjustment can be performed in real time to keep the roller 3 level.

[0030] In actual application, the roller 3 is not homogeneous as a whole due to material or manufacturing errors. When the roller 3 is horizontal, the pressure at both ends of the roller 3 is slightly different. The pressure at both ends of the roller 3 when the roller 3 is horizontal can be recorded as the standard value, that is, the pressure values ​​at both ends of the roller 3 can be set differently to achieve the level of the roller 3. In addition, when the roller 3 needs to be in an inclined state, the inclined state can be maintained.

[0031] In this embodiment, by setting the active adjustment mechanism 1 and the passive adjustment mechanism 2, the adjustment accuracy is high, the operation is convenient for personnel, and time and labor are saved. The combination of the active adjustment mechanism 1 and the passive adjustment mechanism 2 enhances the stability and adaptability of the roller system leveling structure, and can better cope with the adjustment requirements under different working conditions, so that the roller 3 remains horizontal, the roller 3 surface is kept horizontal, wrinkles on the film surface are prevented, the flatness of the film surface is improved, and the production quality is guaranteed.

[0032] like Figure 2As shown, in a preferred embodiment, the active adjustment mechanism 1 includes a vertically arranged linear motion component 101, the linear motion component 101 is used to adjust the height of the end of the roller 3, a pressure sensor 102 is arranged at the movable end of the linear motion component 101, and a bearing seat 301 for supporting the end of the roller 3 is arranged on the top of the pressure sensor 102. The linear motion component 101 is an electric cylinder, and the pressure sensor 102 is arranged on the top of the piston rod of the electric cylinder.

[0033] In this embodiment, when the roller 3 is in an inclined state, the pressure sensor 102 detects the pressure difference between the two ends of the roller 3. The pressure sensor 102 sends the detected pressure value to the control system, and the control system compares the received pressure value with the preset standard value to calculate the height difference between the two ends of the roller 3. The control system sends instructions to the electric cylinder to drive the electric cylinder piston rod to perform a corresponding height lifting action. The lifting and lowering of the electric cylinder piston rod drives the position change of the bearing seat 301, thereby adjusting the height of the end of the roller 3. During the adjustment process, the pressure sensor 102 continuously monitors the pressure at both ends of the roller 3 until the pressure values ​​are equal and the roller 3 reaches a horizontal state.

[0034] In this embodiment, the height of both ends of the roller 3 can be adjusted quickly and accurately through the precise control of the electric cylinder, thereby improving the adjustment efficiency. The pressure sensor 102 and the electric cylinder can be used in conjunction to achieve real-time monitoring and adjustment of the pressure at both ends of the roller 3, ensuring that the roller 3 always remains in a horizontal state.

[0035] In practical applications, the linear motion component 101 may be a ball screw, a linear motor, a rack and pinion, a connecting rod and a slider, a linear module, etc., in addition to the electric cylinder mentioned above.

[0036] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the passive adjustment mechanism 2 includes an elastic member 201 disposed between the linear motion component 101 and the pressure sensor 102, and the elastic expansion direction of the elastic member 201 is the vertical direction. The elastic member 201 is a coil spring, and the lower end of the elastic member 201 is connected to a first support plate 202 connected to the movable end of the linear motion component 101, and the upper end of the elastic member 201 is connected to a second support plate 203 disposed at the bottom of the pressure sensor 102. A limit slide bar 204 is disposed on the first support plate 202, and a limit hole matching the limit slide bar 204 is disposed on the second support plate 203. The upper end of the limit slide bar 204 passes through the limit hole and is slidably connected to the limit hole, and the elastic member 201 is sleeved on the outer side of the limit slide bar 204. A linear bearing is disposed in the limit hole, and the limit slide bar 204 is slidably connected to the limit hole through the linear bearing.

[0037] In this embodiment, when the roller 3 is in a horizontal state, the elastic members 201 at both ends of the roller 3 have the same pressure and the same amount of compression of the elastic members 201, so that the heights of the two ends of the roller 3 are consistent and the roller 3 is kept horizontal. When the roller 3 is tilted, the pressure sensors 102 at both ends of the roller 3 detect the pressure change, and the linear motion component 101 drives the first support plate 202 to rise and fall, so that the coil spring is stretched or compressed. The coil spring generates a force in the elastic expansion direction, pushing the second support plate 203 to rise and fall accordingly, thereby fine-tuning the height of the end of the roller 3. The limiting slide bar 204 provided on the first support plate 202 cooperates with the limiting hole on the second support plate 203, which, on the one hand, limits the range of adjustment, so that the adjustment direction is always along the vertical direction, ensuring the stability and accuracy of the adjustment; on the other hand, it limits the position of the coil spring to prevent the coil spring from bending or offsetting. The linear bearing in the limiting hole reduces the friction between the limiting slide bar 204 and the limiting hole, thereby improving the smoothness and accuracy of the adjustment.

[0038] In this embodiment, the use of the elastic member 201 enables the passive adjustment mechanism 2 to have good adaptability and can be flexibly adjusted according to pressure changes. By providing the first support plate 202 and the second support plate 203, a stable foundation is provided for the installation and fixation of the elastic member 201, ensuring the accuracy and reliability of the adjustment.

[0039] In practical applications, the elastic member 201 may be an air bag, a pneumatic spring, a spring sheet or other elastic member 201 besides the coil spring mentioned above.

[0040] like Figure 3 As shown, in a preferred embodiment, two groups of elastic members 201 are provided, and the two groups of elastic members 201 are symmetrically distributed on both sides of the vertical plane passing through the center line of the roller 3. In this embodiment, one spring is provided in each group, and the two groups of elastic members 201 are symmetrically distributed on both sides of the vertical plane passing through the center line of the roller 3. The symmetrical distribution makes the adjustment mechanism more evenly stressed, preventing fatigue and damage caused by excessive force on one side. In addition, the shaking and instability of the end of the roller 3 caused by external force is reduced, forming a stable supporting force, so that the end of the roller 3 maintains a stable position.

[0041] like Figure 2As shown, in a preferred embodiment, a support seat 4 is provided below the second support plate 203, and the support seats 4 at both ends of the roller 3 are of the same height, and the support seat 4 is connected to the inner wall of the electroplating equipment. In this embodiment, the support seat 4 preferentially supports the second support plate 203, and when the roller 3 is tilted, it is supported by the elastic member 201. Since the support seat 4 is connected to the inner wall of the electroplating equipment, the stability is better. When the roller 3 is horizontal, the roller 3 is supported by the support seat 4, which is more stable. In addition, it can play the role of limit protection. When the elastic member 201 is damaged or unable to support, the support seat 4 can support the roller 3 to prevent the roller 3 from falling and being damaged, and prevent injury, thereby improving the safety of use.

[0042] An electroplating device in one embodiment of the utility model includes the above roller leveling structure, which can keep each roller 3 in the electroplating device level, thereby ensuring that the film is kept flat in the electroplating device, thereby ensuring the quality of film electroplating.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
