Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thin material thinning, in particular to a thin material electrolytic processing device and a thin material electrolytic processing equipment. BACKGROUND

[0002] As a core material in many fields such as flexible circuit substrate, lithium battery current collector, etc., the processing precision and surface quality of ultra-thin thin material can directly determine the performance of the final product. With the rapid development of new energy, semiconductor, aerospace and other high-tech industries, the processing demand of ultra-thin thin material will be more and more, but the traditional mechanical thinning process such as rolling, cutting and grinding has obvious limitations, resulting in mechanical stress damage on the surface of thin material and low efficiency.

[0003] Electrolytic thinning technology is a non-contact processing technology based on electrochemical dissolution principle, which has many advantages such as no mechanical stress, high precision control and environmental friendliness, and has become a key technology to solve the problem of thin material processing. In the electrolytic processing process, the thin material is continuously fed and contacted with the electrolyte for continuous electrolytic processing. The electrolyte is easy to leak from the processing area. The leaked electrolyte not only affects the processing quality of the thin material, but also corrodes the equipment parts and shortens the service life of the equipment. Therefore, how to avoid the leakage of electrolyte has become a technical problem to be solved. SUMMARY

The electrolysis principle is that when the power supply is connected, the thin material as an anode is electrochemically dissolved in the electrolyte environment, and the material is removed layer by layer in the form of ions. In this way, the dynamic sealing structure formed on the circumferential two sides of the conductive roller by the upper sealing clamp and the lower sealing clamp effectively restricts the electrolyte in the processing area, solves the problem of electrolyte leakage from the curved roller surface processing area, avoids the problems of pitting corrosion, stray corrosion and corrosion of equipment parts caused by electrolyte leakage.

[0046] In the specific implementation, please refer to Figures 1-5The electrolytic processing device 100 provided by the present application, the conductive roller 120 is rotatably arranged on the frame 110 for supporting and conveying the thin material 600, and the thin material 600 is electrified by connecting the power supply; the electrolytic processing assembly 130 is movably arranged above the conductive roller 120, the conductive part 1314 thereof serves as a cathode and supplies electrolyte through the flow guide channel 1313; the upper sealing clamp 140 is fixed to the electrolytic processing assembly 130, and the two upper extension parts 141 thereof extend downward; the lower sealing clamp 150 is movably arranged on the frame 110 and located below the conductive roller 120, and the lower extension part 151 thereof corresponds to the upper extension part 141. During operation: the thin material 600 passes through the gap between the upper extension part 141 and the lower extension part 151 and is attached to the roller surface of the conductive roller 120 for conveying, the upper sealing clamp 140 and the lower sealing clamp 150 move towards each other, so that the extension parts thereof are close to the upper surface and the lower surface of the thin material 600, and a sealed cavity surrounding the processing area is formed on the circumferential two sides of the conductive roller 120; the electrolyte flows into the processing area from the flow guide channel 1313 through the through hole 142 of the upper sealing clamp 140, and flows along the upper surface of the thin material 600, when the electrolyte flows to the close position of the upper surface of the thin material 600 and the upper extension part 141, the electrolyte is blocked by the upper extension part 141 and cannot continue to move along the circumference of the thin material 600, and the upper extension part 141 blocks the electrolyte from flowing outward along the circumference, and then the electrolyte flows along the two ends in the width direction of the thin material 600, and is divided into two parts towards the two ends of the axis of the conductive roller 120, the reacted electrolyte is divided into two parts towards the two ends of the axis of the conductive roller 120 without the thin material 600, and flows along the conductive roller 120 to the lower end of the lower sealing clamp 150, and then reaches the liquid outlet hole 152 opened in the lower sealing clamp 150 and is discharged. The electrolysis principle is that when the power supply is connected, the thin material 600 as an anode is electrochemically dissolved in the electrolyte environment to realize the removal of materials in the form of ions layer by layer. By arranging the dynamic sealing structure formed on the circumferential two sides of the conductive roller 120 by the upper sealing clamp 140 and the lower sealing clamp 150, the electrolyte is effectively constrained in the processing area, the problem of electrolyte leakage from the curved roller surface processing area is solved, the problems of pitting corrosion, stray corrosion and corrosion of equipment parts in the non-processing area of the thin material 600 caused by electrolyte leakage are avoided. This not only protects the equipment and prolongs the service life, but also significantly improves the electrolytic processing precision and uniformity of the thin material 600 by maintaining the stability of the flow field in the processing area.

[0047] In some embodiments, as Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the lower sealing clamp 150 is movably arranged on the rack 110 by a height adjusting rod arranged on the rack 110. Specifically, a threaded hole is arranged on the rack 110 in the height direction of the rack 110, the threaded hole is above the lower sealing clamp 150, the height adjusting rod is a threaded rod, the threaded rod is arranged in the threaded hole and is fixedly connected with the lower sealing clamp 150 at the lower end. In this way, the height of the lower sealing clamp 150 can be adjusted by rotating the threaded rod to cooperate with the upper sealing clamp 140, effectively limiting the main flow area of the electrolysis process and the electrolyte in the surrounding area of the upper sealing clamp 140 and the lower sealing clamp 150, and the adjustable arrangement of the lower sealing clamp 150 can adapt to thin materials 600 of different thicknesses to ensure the sealing effect. It can be understood that, since the thin material 600 is continuously transported in the feeding direction, when the upper sealing clamp 140 and the lower sealing clamp 150 act, the upper sealing clamp 140 does not abut against the upper surface of the thin material 600, that is, the upper sealing clamp 140 only approaches the upper surface of the thin material 600 under the driving action, and a gap exists between the upper sealing clamp 140 and the upper surface of the thin material 600, which can play a role in blocking the electrolyte splashing and guiding the electrolyte. The lower sealing clamp 150 also does not abut against the lower surface of the thin material 600, and the lower sealing clamp 150 only approaches the lower surface of the thin material 600, and a gap exists between the lower sealing clamp 150 and the lower surface of the thin material 600, which can play a role in blocking the electrolyte splashing. It can be understood that the upper end of the threaded rod can be provided with a rotating handle to facilitate the movement of the lower sealing clamp 150.

[0048] As a possible implementation manner, as shown in Figure 7 and Figure 8 As shown, the electrolytic machining assembly 130 includes a flow guide component 131 movably arranged above the conductive roller 120, the flow guide component 131 is internally provided with a flow guide channel 1313, a plurality of first liquid inlets 1311 and a plurality of first liquid outlets 1312 in communication with the flow guide channel 1313, the plurality of first liquid inlets 1311 are used to introduce electrolyte, and the plurality of first liquid outlets 1312 are located on the lower surface of the flow guide component 131; a conductive part 1314 is fixedly arranged on the lower surface of the flow guide component 131, and the upper sealing clamp 140 is fixedly arranged on the lower surface of the flow guide component 131. Specifically, the electrolyte enters the flow guide component 131 through the plurality of first liquid inlets 1311, flows out from the plurality of first liquid outlets 1312 after flowing through the flow guide channel 1313, and flows into the machining area through the through hole 142 of the upper sealing clamp 140 to perform electrolytic machining. In this way, by integrating the conductive part 1314 and the upper sealing clamp 140 on the lower surface of the flow guide component 131, the electrolyte supply, the electric field formation and the sealing protection three function modules are arranged concentratedly, which ensures the accurate positioning of the electrolysis area and the sealing area and improves the compactness and working reliability of the equipment.

[0049] Further, as shown in Figure 7As shown, the plurality of first liquid outlets 1312 are uniformly spaced along the axial direction of the conductive roller 120 and arranged on the lower surface of the flow guide component 131.

[0050] In this way, the plurality of liquid outlets are arranged on the lower surface of the flow guide component 131 in an equidistant manner. During operation, when the electrolyte is transported through the flow guide channel 1313, it will flow out from the plurality of uniformly distributed first liquid outlets 1312 at the same time, forming a continuous and uniformly distributed electrolyte liquid curtain on the surface of the thin material 600 in the axial direction of the conductive roller 120. By uniformly arranging the first liquid outlets 1312 along the axial direction of the conductive roller 120, it is ensured that the electrolyte can uniformly cover the area to be processed of the thin material 600 in the width direction, avoiding the problem of local over-processing or under-processing caused by uneven liquid flow distribution, and improving the uniformity of electrolytic processing and the surface quality of the thin material 600. In some embodiments, the uniformly spaced liquid outlets can be arranged in a single row, double rows, or a rectangular array.

[0051] As a possible implementation, as shown in Figure 6 As shown, the electrolytic processing assembly 130 further comprises a flow equalization component 132 movably arranged above the flow guide component 131. The flow equalization component 132 is provided with a tapered cavity, a second liquid inlet 1321, and a plurality of second liquid outlets 1322. The plurality of second liquid outlets 1322 correspond one-to-one to the plurality of first liquid inlets 1311. The tapered cavity comprises a plurality of flow distribution cavities arranged symmetrically about the center of the flow equalization component 132, and the plurality of flow distribution cavities correspond one-to-one to the plurality of second liquid outlets 1322.

[0052] In specific implementation, the electrolyte enters the tapered cavity through the second liquid inlet 1321, is evenly distributed through the plurality of flow distribution cavities in the tapered cavity, and then flows out synchronously through the second liquid outlets 1322. The second liquid outlets 1322 correspond one-to-one to the plurality of first liquid inlets 1311 of the flow guide component 131 and are in communication therewith. Finally, the electrolyte is uniformly sprayed onto the surface of the thin material 600 through the first liquid outlets 1312 arranged on the lower surface of the flow guide component 131. At the same time, the conductive roller 1314 is connected to the cathode power supply, and an electrolytic loop is formed with the positively charged thin material 600. Through the multi-cavity flow distribution design of the flow equalization component 132 and the multi-outlet layout of the flow guide component 131, the uniformity of the electrolyte covering the surface of the thin material 600 is effectively ensured, and the thickness difference caused by local flow rate unevenness is avoided. At the same time, the modular cavity structure facilitates maintenance and cleaning. In addition, the design of the plurality of first liquid outlets 1312 allows the electrolyte to more uniformly cover the entire surface of the thin material 600, disperses the impact pressure of the electrolyte, avoids the problem of pressure concentration, and provides a good flow field environment for electrolytic processing.

[0053] As a possible implementation, as shown in Figure 8As shown, the outlet direction of the multiple first outlets 1312 is inclined to the surface of the electrolysis area of ​​the thin material 600. That is, the flow direction of the electrolyte flowing out through the first outlets 1312 and onto the thin material 600 is not perpendicular to the surface of the thin material 600. Specifically, a deflector can be provided at one end of the guide member 131 near the thin material 600, and the guide channel 1313 of the guide member 131 forms a bend at the deflector, so that the electrolyte flowing to the bend of the guide channel 1313 changes its flow direction in a specific direction. The flow direction of the electrolyte can be changed by altering the size of the bending arc, so that the flushing direction of the electrolyte is consistent with the feeding direction of the thin material 600, which is beneficial for timely discharge of electrolytic products and improves surface quality. Furthermore, the steering head can be detachably mounted on the flow guiding component 131. Through the detachable design, different steering heads with different bending arcs can be quickly mounted and dismounted from the flow guiding component 131, which can easily change the angle of the electrolyte impacting the surface of the thin material 600. Only different steering heads need to be replaced.

[0054] In some embodiments, such as Figure 1 and Figure 6 As shown, the number of distribution chambers can be six, eight, or ten. When the electrolyte is injected into the distribution chamber from the second inlet 1321, it will reach the second outlet 1322, which is set one-to-one with the distribution chamber, through the centrally symmetrically distributed conical distribution chambers. It will then be evenly discharged from multiple second outlets 1322 to the first inlet 1311 of the flow guide component 131, forming a complete fluid passage. The equal cross-sectional area design of multiple distribution chambers and the coordinated cooperation of the centrally symmetrical layout ensure the consistency of electrolyte flow in each branch, achieving efficient distribution and delivery of electrolyte while ensuring the compactness of the system. Furthermore, the diffusion angle of each flow divider cavity, that is, the angle between the axis of each flow divider cavity and the axis of the conical cavity, is 18°~22°, specifically 18°, 19°, 20°, 21° and 22° and any degree within the range. When the diffusion angle is the above degree, the flow divider cavity exhibits a uniform streamline distribution pattern, the electrolyte flow state is stable, and the flow velocity field of each second outlet 1322 is uniform and the same. While ensuring that the electrolyte flow path is short so as not to affect the flow efficiency, the flow divider cavity does not generate or generates a small number of eddy current regions, thus achieving a good flow distribution effect.

[0055] As one possible implementation, such as Figure 4 and Figure 5 As shown, the thin material electrolytic processing apparatus 100 also includes a plurality of tension rollers 160, which are rotatably mounted on the frame 110. The tension rollers 160 are mounted at different heights and are all lower than the mounting height of the conductive roller 120. The thin material 600 contacts the upper circumferential side of the conductive roller 120 and the lower circumferential side of a tension roller 160 adjacent to the conductive roller 120.

[0056] Specifically, a plurality of tension rollers 160 are also arranged on the rack 110, and the thin material 600 forms a suspended wrapping contact section between the top of an adjacent conductive roller 120 and the bottom of the tension roller 160. In operation, the driving system drives the rotation of the tension rollers 160 and the working roller to convey the thin material 600, and the thin material 600 keeps contact with the surface of the conductive roller 120 to ensure circuit conduction when passing above the conductive roller 120. When the thin material 600 passes from the bottom of the tension roller 160 at a lower position to the top of the conductive roller 120, the angle formed by the height difference makes the thin material 600 tightly adhere to the surface of the conductive roller 120, ensuring good electrolytic contact. At the same time, the plurality of tension rollers 160 with different heights cooperate to provide stable tension to the thin material 600. The arrangement of the thin material 600 forming a suspended wrapping contact section between the top of an adjacent conductive roller 120 and the bottom of the tension roller 160 further expands the angle of the thin material 600, further ensuring that the thin material 600 can tightly adhere to the surface of the conductive roller 120, ensuring good electrolytic contact. Through the staggered arrangement of the roller system, the wrapping force on the conductive roller 120 is naturally formed by the path change of the thin material 600 itself, which not only ensures reliable electrical contact between the thin material 600 and the conductive roller 120, but also provides necessary tension control for the stable conveying of the thin material 600, creating stable processing conditions for electrolytic processing. It can be understood that the number of tension rollers 160 is a plurality, which can be three, four, five or more. When the number of tension rollers 160 is three, the three tension rollers 160 are arranged at different heights on the rack 110, and the thin material 600 is wrapped around the plurality of tension rollers 160 to meet the tension requirement of the thin material 600. In addition, a vertical roller machine containing guide rollers can also be arranged in front of the tension rollers 160 and the rack 110, and the thin material 600 is fed to the tension rollers 160 and the conductive roller 120 through the guiding action of the guide rollers to ensure the stability of the feeding of the thin material 600 to achieve better electrolytic thinning effect.

[0057] In some embodiments, as Figure 2As shown, the edge of the through hole 142 of the upper sealing clamp 140 is provided with an inclined surface, and the inclination direction of the inclined surface is the same as the liquid outlet direction of the first liquid outlet 1312. Specifically, the inclined surface is formed on the upper edge around the through hole 142 of the upper sealing clamp 140, and the inclination angle of the inclined surface is parallel to the central axis direction of the first liquid outlet 1312 of the flow guide component 131. During operation, the electrolyte flow vertically ejected from the first liquid outlet 1312 flows into the through hole 142 along the inclined surface, and the flow direction flows into the upper surface of the thin material 600 along the inclination direction of the inclined surface, so that the electrolyte can smoothly spread along the feeding direction of the thin material 600. By setting the inclined flow guide surface consistent with the liquid outlet direction, the electrolyte flowing to the thin material 600 is converted into a uniform flow field in the feeding direction of the thin material 600, effectively eliminating the impact of the vertical jet flow on the surface of the thin material 600, ensuring the uniformity and flowability of the electrolyte distribution in the processing area, thereby improving the surface uniformity and processing quality of the thin material 600.

[0058] It can be understood that the through hole 142 is provided on the upper surface of the upper sealing clamp 140 and penetrates up and down, and the through hole 142 can be a strip-shaped through hole 142, a rectangular through hole 142 or an elliptical through hole 142, etc.

[0059] In some embodiments, the working roller surface of each of the plurality of tension rollers 160 and the conductive roller 120 is provided with an annular groove in the circumferential direction, and the annular groove is used to accommodate the thin material 600 to limit the thin material 600 in the axial direction of the tension roller 160. During operation, when the thin material 600 is fed into the feeding device and contacts each tension roller 160 and the working roller, the edge part of the thin material 600 is embedded in the corresponding groove of each tension roller 160 and the conductive roller 120, and as the tension roller 160 and the conductive roller 120 rotate, the side wall of the groove continuously restricts the side of the thin material 600, thereby limiting the movement of the thin material 600 in the axial direction of the roller body. By providing an annular groove on the surface of each tension roller 160 and the conductive roller 120, a continuous axial constraint is provided for the running thin material 600, preventing the thin material 600 from running transversely or sliding during transportation, and ensuring that the thin material 600 always smoothly passes through the electrolytic processing area along the predetermined path, thereby providing position accuracy guarantee for the thin material 600 to obtain uniform thinning effect.

[0060] Please refer to Figure 1 and Figure 9In another aspect, the embodiment of the present application also provides a thin material electrolytic processing equipment, comprising the thin material electrolytic processing device 100, the rack body 200, the driving motor 300 and the screw sliding block mechanism in any of the above embodiments; wherein the driving electrolysis is fixedly arranged on the rack body 200; the screw sliding block mechanism is located on the side of the rack body 200 close to the thin material electrolytic processing device 100, and comprises a screw and a first sliding block engaged with the screw; the screw is connected with the driving end of the driving motor 300, the axial direction of the screw faces the thin material 600, and the electrolytic processing assembly 130 is fixedly connected with the first sliding block.

[0061] In the above technical solution, the rack body 200 serves as an overall support structure, the driving motor 300 is fixedly arranged on the upper part of the rack body 200, the screw sliding block mechanism is located on the side of the rack body 200 close to the thin material electrolytic processing device 100, the screw of the screw sliding block mechanism is connected with the driving end of the driving motor 300 and faces the thin material 600 in the axial direction, the first sliding block is engaged with the screw, and it can be understood that the first sliding block also comprises a sliding extension surface in contact with the rack body 200, so that when the screw sliding block mechanism drives the first sliding block to move, the rotation trend of the first sliding block is inhibited so that the first sliding block can only move linearly along the axial direction of the screw, and the electrolytic processing assembly 130 in the thin material electrolytic processing device 100 is fixedly connected with the first sliding block. In the working process: the driving motor 300 drives the screw to rotate, and then drives the first sliding block and the entire electrolytic processing assembly 130 fixedly arranged thereon to stably and accurately approach or move away from the thin material 600 below along the axial direction of the screw; when the electrolytic processing assembly 130 moves downward, the upper sealing clamp 140 cooperates with the rising lower sealing clamp 150 to form a seal to the thin material 600, and the small processing gap between the electrolytic processing assembly 130 and the surface of the thin material 600 can be accurately controlled. In this way, the precise feeding of the electrolytic processing assembly 130 is completed through the screw sliding block mechanism, the optimal electrolytic gap can be maintained, the reliability and consistency of the dynamic sealing of the upper sealing clamp 140 and the lower sealing clamp 150 are ensured, the leakage of the electrolyte is prevented, and stable motion control is provided for obtaining high-quality electrolytic thinning effect.

[0062] In actual application, the screw sliding block mechanism can adopt a ball screw sliding block mechanism, and the inclination angle of the screw sliding block mechanism can be designed according to the overall layout of the equipment; the driving motor 300 is connected with the screw sliding block mechanism through a shaft coupling, and a speed reducer is further connected between the driving motor 300 and the screw sliding block mechanism, so as to increase the torque applied to the screw sliding block mechanism and realize more accurate position driving positioning.

[0063] As a possible implementation manner, as shown in Figure 9As shown, the thin material electrolytic processing equipment further comprises a bearing seat fixedly arranged on one side of the frame 200 close to the electrolytic processing device, and a lead screw is rotatably arranged on the bearing seat. The bearing seat is provided with a guide mechanism, which comprises a guide rail and a second sliding block arranged axially parallel to the lead screw. The second sliding block is slidingly arranged on the guide rail and is fixedly connected with the first sliding block.

[0064] Specifically, the driving device further comprises a bearing seat fixedly arranged on one side of the frame 200 close to the electrolytic processing device by means of bolts, and a lead screw is rotatably arranged on the bearing seat by means of a bearing. The bearing seat is provided with a guide mechanism, which comprises a guide rail and a second sliding block arranged axially parallel to the lead screw sliding block mechanism. The second sliding block is slidingly arranged on the guide rail and is fixedly connected with the first sliding block by means of bolts. In the working process, when the driving motor 300 drives the lead screw to rotate, the second sliding block slidingly arranged on the guide rail is fixedly connected with the first sliding block. The second sliding block rigidly connected with the first sliding block slides along the guide rail, and the guide rail bears the radial force and torque generated by the first sliding block, so that the first sliding block can only move linearly along the guide rail, thereby avoiding the possible torsion or deviation of the lead screw sliding block mechanism transmission. By arranging the guide rail sliding block pair parallel to the lead screw sliding block mechanism as the guide mechanism, the possible deviation or jamming of the electrolytic device in the feeding process is effectively eliminated, and the straightness and stability of the movement trajectory are ensured, thereby providing a key guarantee for maintaining the precise and stable electrolytic gap. In actual application, the guide rail can adopt various forms such as a ball guide rail, a roller guide rail or a sliding guide rail; the bearing seat can be designed as a split structure for easy installation and adjustment; and a baffle can be arranged at the bearing seat at both ends of the guide rail to protect the mechanism.

[0065] As a possible implementation manner, as shown in FIG. 6, Figure 9As shown, the thin material electrolytic machining equipment further comprises counterweights 400 and connecting ropes 500, the counterweights 400 are arranged on opposite sides of the frame 200 away from the screw block mechanism, and the two ends of the connecting ropes 500 are connected to the counterweights 400 and the electrolytic machining assembly 130 respectively. Specifically, the counterweights 400 are arranged on the side of the frame 200 away from the electrolytic machining assembly 130, one end of the connecting ropes 500 is connected to the counterweights 400, and the other end is connected to the electrolytic machining assembly 130 after passing through the turning mechanism on the top of the frame 200. During operation, the gravity generated by the counterweights 400 is converted into an upward lifting force on the electrolytic machining assembly 130 through the connecting ropes 500 and the turning mechanism, which counteracts the downward gravity of the electrolytic machining assembly 130, so that the driving motor 300 only needs to provide a small power to overcome the friction and maintain the movement to realize the lifting of the electrolytic machining assembly 130. At the same time, on the one hand, arranging one end of the connecting ropes 500 on the electrolytic machining assembly 130 effectively eliminates the axial load of the screw block mechanism transmission system caused by the weight of the electrolytic machining assembly 130, improves the stability and precision of the feeding motion, and prolongs the service life of the transmission components; on the other hand, it also optimizes the single-sided stress condition of the frame 200, improves the service life and stability of the frame 200. In practical application, the connecting ropes 500 can be steel wire ropes or chains; an emergency brake device can also be arranged on one side of the counterweight 400 as a safety protection.

In the electrolytic machining environment, the risk of communication between the cast iron bed and the electrolytic machining assembly 130 is eliminated. By using the support structure composed of the cast iron bed and the marble platform, the overall rigidity of the equipment foundation and the long-term stability of the installation reference plane are considered, the vibration transmission and structural deformation during machining are effectively suppressed, and reliable support is provided for realizing high-precision electrolytic thinning.
