A device and method for processing PCB solid-state battery board oil-sealed etched leads

Abstract

The present invention discloses a device and method for processing oil-sealed etched leads of a PCB solid-state battery panel, and relates to the technical field of PCB solid-state battery panel processing. In the process of removing the coating during electroplating on the surface of the PCB solid-state battery panel, the present invention utilizes an inclined swing plate, a coating roller, and a coating belt. When processing the coating on the surface of the battery panel, the battery panel pushes the swing plate to rotate to a horizontal state, so that a liquid replenishing mechanism is opened to replenish the coating roller and the coating belt with processing liquid. The processing liquid coated on the battery panel by the coating belt is stored separately, and the concentration of the processing liquid remains unchanged. After the coating belt completes coating the battery panel, the swing plate can be restored to an inclined state, so that the processing liquid inside the coating belt can be gathered and drained to one side, thereby avoiding the backflow of the processing liquid. When the swing plate is tilted, the coating roller is separated from the storage bin, and the processed coating residue will not enter the storage bin and contaminate the processing liquid in the storage bin.

Description

Technical Field

[0001] The present invention relates to the technical field of PCB solid-state battery board processing, and in particular to a device and method for processing oil-sealed etched leads of a PCB solid-state battery board. Background Art

[0002] During the production of PCB solid-state solar panels, nickel and gold plating are required to enhance the electrical performance of the panels. During the nickel and gold plating process, wet and dry films are applied to the surface of the panels. After the plating is completed, the coating is usually removed by soaking or coating with a treatment solution.

[0003] The advantage of coating is that the coating is removed by consuming the liquid, which ensures that the concentration of the active ingredients in the liquid is fixed, thus ensuring good product consistency. The actuator of the existing coating device is usually set on the lower side of the workpiece. The purpose is to make the actuator absorb the coating liquid simply and evenly. When the workpiece is an etched battery panel, the etching residue is easily adhered by the actuator and introduced into the liquid storage tank. When the actuator is located on the upper side of the workpiece, the actuator can be prevented from being immersed in the liquid storage tank by dripping liquid. However, the technical barriers that need to be solved by this setting method are the need to avoid excessive supply of processing liquid and the centralized drainage of residual coating liquid on the actuator after coating is completed, so as to facilitate subsequent processing.

Two receiving plates are fixedly connected to the inner wall of the sliding shell corresponding to the bottom of the sealing plate. When the two receiving plates are in contact with the sealing plate, they are used to seal the inside of the sliding shell. A triangular toggle block is fixedly connected to the surface of the coating roller for squeezing the push block to move upward.

[0010] As a further solution of the present invention, an arc-shaped protective plate is fixedly connected between the front and rear corresponding protective shells, and the two protective plates are respectively fitted with the side surfaces close to the two coating rollers.

[0011] As a further solution of the present invention, a block is fixedly connected to the surface of the protective shell away from the sliding shell, and a blocking rod is slidably connected to the inner wall of the installation box.

[0014] As a further solution of the present invention, a discharge cover is provided on the surface of the temporary storage box.

[0015] The present invention also provides another technical solution, a method for processing oil-sealed etched leads of a PCB solid-state battery panel, the specific steps of the method are as follows:

[0016] Step 1: Plan the overall layout of the internal leads according to the panel design requirements and determine the location and direction;

[0017] Step 2: The solar panel is pre-treated by deoxidation and degreasing, and the wet film is covered by silk screen printing. After exposure and development, the nickel-plated area is exposed;

[0018] Step 3: The battery plate is pre-treated before nickel plating. After being immersed in the electrolyte, current is passed through it, and parameters such as current density, temperature, and stirring are controlled to ensure the quality of the coating.

[0019] Step 4: Laminating the dry film on the nickel-plated solar cell board and exposing and developing the gold-plated area;

[0020] Step 5: Immerse the dry film-coated solar panel in an electrolyte containing gold ions. Apply current to reduce and deposit the gold ions at the gold-plating location. The current is conducted through the internal leads to precisely control the gold-plating area.

[0021] Step 6: After the gold plating is completed, use the PCB solid-state battery board sealing oil etching lead processing device to remove the wet and dry films on the board surface. After removing the film, rinse with deionized water and dry;

[0022] Step 7: Apply solder mask ink to the non-lead and non-welding areas of the solar panel to seal the oil. After coating, perform pre-curing treatment. After the ink is initially cured, perform high-temperature curing to completely cure the solder mask layer, enhance insulation and corrosion resistance, and protect the nickel-gold plated lead part from being affected by subsequent processes.

[0023] Step 8: Press the dry film onto the solar panel again, covering all parts except the internal leads. Remove the internal leads by etching. After etching, remove the dry film by stripping it off. Then, rinse thoroughly with deionized water and dry. Check the lead resistance and other parameters to ensure that the circuit performance meets the standards before proceeding to the subsequent testing and assembly stages.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention utilizes an inclined swing plate, coating roller, and coating belt to remove the coating film from the surface of a PCB solid-state battery panel during electroplating. When treating the coating film on the panel surface, the panel pushes the swing plate to rotate to a horizontal position, causing a refill mechanism to open and replenish the coating roller and coating belt with treatment liquid. The coating belt then evenly applies the treatment liquid to the panel surface, enabling rapid removal of the coating film. The coating belt separately stores the treatment liquid applied to the panel, maintaining a constant concentration of the treatment liquid. This facilitates control over the time it takes for the treatment liquid to effectively remove the coating film from the panel surface, ensuring effective treatment of the panel surface by the treatment liquid and preventing film residue and excessive corrosion caused by changes in treatment liquid concentration during film removal. After the coating belt finishes coating the panel, the swing plate can return to its inclined position, allowing the treatment liquid within the coating belt to be concentrated and drained to one side, preventing backflow of the treatment liquid. When the swing plate is tilted, the coating roller is separated from the storage bin, preventing treated film residue from entering the storage bin and contaminating the treatment liquid therein.

[0026] 2. In the process of removing the film on the surface of the solar panel of the present invention, when the sliding shell rotates to a horizontal state on the swing plate, the replenishing port on the surface of the sliding shell is connected to the interior of the storage bin, and the treatment liquid is replenished into the coating roller. When the coating roller drives the coating belt to move, the multiple water-permeable gaps can make the coating belt evenly absorb the treatment liquid during movement. By replenishing the treatment liquid into the coating roller, the coating belt does not directly contact the treatment liquid inside the storage bin, thereby ensuring the stability of the treatment liquid concentration and performance inside the storage bin and preventing the film residue remaining after the surface treatment of the coating belt from flowing back into the storage bin and contaminating the treatment liquid in the storage bin. When the solar panel moves out from under the swing plate, the coating roller moves downward and disengages from the sliding shell. The sliding shell moves downward, and the replenishing port is blocked by the blocking plate again, which is conducive to timely cutting off the treatment liquid after the treatment of the solar panel is completed, avoiding excessive outflow of the treatment liquid, resulting in waste of the treatment liquid, and affecting the uniformity of the coating belt absorbing the treatment liquid.

[0027] 3. During the process of removing the film from the surface of the solar panel, the present invention utilizes a protective shell and a connecting tube to allow the treatment liquid to enter the grooves and connecting grooves on the surfaces of the two coating rollers, thereby increasing the rate at which the coating belt absorbs the treatment liquid and ensuring uniform coating of the treatment liquid on the solar panel surface by the coating belt, thereby ensuring the treatment effect of the treatment liquid on the film on the solar panel surface.

DETAILED DESCRIPTION

[0043] See also Figures 1-13 The present invention provides a technical solution: a processing device for sealing oil and etching leads of a PCB solid-state battery panel, comprising a mounting box 5 with an opening at the bottom, a storage bin 6 for storing a processing liquid fixedly installed inside the mounting box 5, mounting grooves 7 are provided on the front and rear inner walls of the mounting box 5 corresponding to the lower side of the storage bin 6, a tilted swing plate 8 is elastically hinged in the mounting groove 7, two coating rollers 9 are rotatably connected between the two swing plates 8, and a coating belt 13 is transmission-connected to the surface of the two coating rollers 9, and a liquid replenishing mechanism is provided at the bottom of the storage bin 6 corresponding to the end of the coating roller 9; the liquid replenishing mechanism is used to replenish the processing liquid into the coating roller 9 and the coating belt 13 when the battery panel moves horizontally to the lower side of the mounting box 5 and pushes the swing plate 8 to rotate to the horizontal direction;

[0044] In the process of removing the coating during electroplating on the surface of the PCB solid-state battery panel, after the clamping frame 3 clamps the battery panel (denoted by S in the accompanying drawings), the clamping frame 3 and the battery panel are driven by an external driving device to move along the slide rail 2 in the cleaning cylinder 1 to the bottom of the installation box 5. At this time, the swing plate 8 is in an inclined state. Subsequently, when the battery panel moves horizontally along the slide rail 2 to the position of the swing plate 8 (as shown in the accompanying drawings), the battery panel is moved horizontally to the position of the swing plate 8. Figure 4As shown in the figure, the solar panel pushes the swing plate 8 to rotate to a horizontal state, and the coating roller 9 pushes the refilling mechanism to open the refilling mechanism. The treatment liquid in the storage bin 6 is replenished into the coating roller 9 through the refilling mechanism. Then, after the solar panel moves to the coating belt 13 position, the coating roller 9 drives the coating belt 13 to move, and a relative displacement occurs between the coating belt 13 and the solar panel. The coating belt 13 absorbs the treatment liquid inside the coating roller 9 and evenly coats it on the surface of the solar panel, so that the coating on the surface of the solar panel can be quickly removed. The coating belt 13 stores the treatment liquid applied to the solar panel separately, and the concentration of the treatment liquid is maintained. The coating strip 13 is kept constant, which is convenient for controlling the time of removing the coating on the surface of the solar panel by the treatment liquid, ensuring the consistency of the coating treatment on the surface of the solar panel by the treatment liquid, and avoiding the problem of coating residue or excessive corrosion caused by the change of the treatment liquid concentration when the treatment liquid is removing the coating. After the coating strip 13 has finished coating the solar panel, the swing plate 8 can be restored to the inclined state, so that the treatment liquid inside the coating strip 13 can be gathered to one side. When the swing plate 8 is tilted, the coating roller 9 is separated from the storage bin 6, and the treated coating residue will not enter the storage bin 6 to pollute the treatment liquid in the storage bin 6.

[0045] As a further solution of the present invention, the liquid replenishing mechanism includes a through-port 14 opened at the bottom of the storage bin 6, and a blocking plate 15 is fixedly connected to both sides of the inner wall of the storage bin 6 corresponding to the through-port 14. A sliding shell 16 is elastically slidably connected in the through-port 14, and the bottom of the sliding shell 16 is arc-shaped. A replenishing port 17 is opened on both sides of the sliding shell 16 close to the blocking plate 15. The replenishing port 17 is located above the coating roller 9. A plurality of arc-shaped grooves 10 are opened at both ends of the surface of the coating roller 9, and a connecting groove 11 is opened between the corresponding grooves 10 at both ends. A water-permeable slit 12 that passes through the coating roller 9 is opened near the surface of the coating roller 9.

[0046] In the process of removing the film on the surface of the solar panel, when the swing plate 8 rotates to a horizontal state, the coating roller 9 at the bottom of the sliding shell 16 moves upward and contacts the bottom of the sliding shell 16, pushing the sliding shell 16 to move upward together, and the replenishing port 17 moves to the top of the blocking plate 15 and communicates with the inside of the storage bin 6. The treatment liquid inside the storage bin 6 enters the inside of the sliding shell 16 through the replenishing port 17. When the coating roller 9 rotates, the treatment liquid inside the sliding shell 16 can flow along the groove 10 on the surface of the coating roller 9 to the inside of the communicating groove 11, and flow out through the water-permeable slit 12 to contact the coating belt 13. When the coating roller 9 drives the coating belt 13 to move, the multiple water-permeable slits 12 can make the coating belt 13 move. The coating belt 13 uniformly absorbs the treatment liquid during movement, and replenishes the treatment liquid into the coating roller 9 so that the coating belt 13 does not directly contact the treatment liquid in the storage bin 6, thereby ensuring the stability of the treatment liquid concentration and performance in the storage bin 6, and preventing the coating residue remaining after the surface treatment of the coating belt 13 from flowing back into the storage bin 6 and causing pollution to the treatment liquid in the storage bin 6. When the battery panel moves out from under the swing plate 8, the coating roller 9 moves downward and disengages from the sliding shell 16. The sliding shell 16 moves downward, and the replenishing port 17 is blocked by the blocking plate 15 again, which is conducive to timely cutting off the treatment liquid after the battery panel treatment is completed, avoiding excessive outflow of the treatment liquid, causing waste of the treatment liquid, and affecting the uniformity of the coating belt 13 absorbing the treatment liquid.

[0047] During the process of removing the film from the surface of the solar panel, the surface of the coating roller 9 on the side away from the sliding shell 16 cannot come into contact with the treatment liquid. As a further solution of the present invention, an arc-shaped protective shell 18 is fixedly connected to the surface of the swing plate 8 at the positions corresponding to the ends of the two coating rollers 9. The groove 10 at the end of the coating roller 9 is partially located inside the protective shell 18. The surface of the protective shell 18 near the sliding shell 16 is provided with an addition port 19. A connecting pipe 20 with an inclined bottom is connected between the two protective shells 18.

[0048] During the process of removing the film on the surface of the solar panel, when the swing plate 8 rotates to a horizontal state, the protective shell 18 moves along with it, and the addition port 19 at the upper end of the protective shell 18 fits with the bottom of the sliding shell 16 to push the sliding shell 16 to move upward. The treatment liquid flows into the interior of the protective shell 18 through the addition port 19 and can then flow to the interior of the protective shell 18 on the other side through the connecting pipe 20, so that the treatment liquid can enter the grooves 10 and the connecting grooves 11 on the surfaces of the two coating rollers 9, thereby increasing the rate at which the coating belt 13 absorbs the treatment liquid, ensuring the uniformity of the coating of the solar panel surface by the coating belt 13, and thus ensuring the treatment effect of the treatment liquid on the film on the solar panel surface.

[0049] During the process of removing the film on the surface of the solar panel, after the sliding shell 16 is pushed open, the treatment liquid inside the storage bin 6 is squeezed out under the action of gravity, resulting in a faster outflow of the treatment liquid, affecting the uniformity of the treatment liquid adsorbed by the coating belt 13. As a further solution of the present invention, a sealing plate 21 is fixedly installed on the top of the inner wall of the sliding shell 16 through an elastic component, and a triangular push block 22 is fixedly connected to the bottom of the sealing plate 21. Two receiving plates 23 are fixedly connected to the inner wall of the sliding shell 16 corresponding to the bottom of the sealing plate 21. When the two receiving plates 23 are in contact with the sealing plate 21, they are used to seal the interior of the sliding shell 16. A triangular toggle block 24 for squeezing the push block 22 to move upward is fixedly connected to the surface of the coating roller 9.

[0050] During the process of removing the film on the surface of the solar panel, the sliding shell 16 is pushed to the internal replenishment port 17 of the storage bin 6 and opened. When the coating roller 9 rotates, the toggle block 24 is driven to rotate synchronously. The toggle block 24 can intermittently push the push block 22 to move upward, and the push block 22 drives the sealing plate 21 to move upward. The sealing plate 21 is separated from the receiving plate 23, and the processing liquid can flow from between the sealing plate 21 and the receiving plate 23 to the protective shell 18. Then, after the toggle block 24 is separated from the push block 22, the sealing plate 21 is re-fitted with the receiving plate 23 to seal the inside of the sliding shell 16, which is conducive to intermittently replenishing the processing liquid into the protective shell 18 when the coating roller 9 rotates, avoiding the processing liquid from flowing out quickly under the action of gravity, thereby affecting the uniformity of the coating belt 13 adsorbing the processing liquid, and then causing the coating belt 13 to be unable to evenly coat the solar panel.

[0051] During the process of removing the film from the surface of the solar panel, after the solar panel is coated, the remaining treatment liquid in the protective shell 18 and the connecting pipe 20 can easily flow out of the protective shell 18 when the swing plate 8 rotates again. As a further solution of the present invention, the surface of the protective shell 18 near the sliding shell 16 is connected to a temporary storage box 25 with an inclined bottom. The temporary storage box 25 has a discharge cover 31 on its surface.

[0052] During the process of removing the coating on the surface of the solar panel, after the solar panel is coated, when the swing plate 8 is rotated to the tilted state again, the remaining treatment liquid in the two protective shells 18 and the connecting pipe 20 can flow into the temporary storage box 25, so as to prevent the remaining treatment liquid from spilling out when the swing plate 8 is rotated to the tilted state, and the treatment liquid inside the temporary storage box 25 can quickly flow back to the inside of the protective shell 18 for use when the swing plate 8 is rotated to the horizontal state again. When the treatment liquid inside the temporary storage box 25 needs to be discharged, the discharge cover 31 can be opened after the swing plate 8 is rotated to the tilted state to discharge the treatment liquid inside the temporary storage box 25.

[0053] During the process of removing the film from the surface of the solar panel, the side of the two coating rollers 9 that is close to each other does not contact the coating belt 13, and the treatment liquid easily flows out and flows along the surface of the coating rollers 9, affecting the uniform absorption of the treatment liquid by the coating belt 13. As a further solution of the present invention, an arc-shaped protective plate 26 is fixedly connected between the front and rear corresponding protective shells 18, and the two protective plates 26 are respectively in contact with the surface of the side of the two coating rollers 9 that is close to each other;

[0054] During the process of removing the film on the surface of the solar panel, the protective plate 26 can block the water-permeable gap 12 on the surface of the side where the two coating rollers 9 are close to each other, preventing the treatment liquid from still flowing out of the water-permeable gap 12 on the surface of the coating roller 9 that is not in contact with the coating belt 13 during the rotation of the coating roller 9. The outflowing treatment liquid flows along the surface of the coating roller 9, which easily causes the coating belt 13 to absorb more treatment liquid, affecting the uniformity of the coating belt 13 absorbing the treatment liquid, thereby affecting the treatment effect of the treatment liquid on the film after the coating belt 13 is coated on the solar panel.

[0055] When the solar panels are continuously processed, the repeated rotation of the swing plate 8 is likely to affect the continuous movement of the subsequent solar panels. As a further solution of the present invention, a block 27 is fixedly connected to the surface of the protective shell 18 on the side away from the sliding shell 16, and a blocking rod 28 is slidably connected to the inner wall of the installation box 5. The blocking rod 28 is used to block and limit the swing plate 8 through the block 27 when the swing plate 8 is in a horizontal state. The blocking rod 28 passes through the installation box 5 and extends to the outside of the installation box 5;

[0056] When the battery panels are continuously processed, after the swing plate 8 rotates to the horizontal, the block 27 rotates to the horizontal under the drive of the swing plate 8 and the protective shell 18, and the block 27 rotates to the top of the blocking rod 28. Then the blocking rod 28 is manually pushed, and the blocking rod 28 moves to the bottom of the block 27 and fits with the bottom of the block 27. The blocking rod 28 limits the swing plate 8 through the block 27, so that the swing plate 8 can be in a horizontal state, which is convenient for continuous processing of the battery panels and improves the processing efficiency.

[0057] During the process of removing the film from the surface of the solar panel, less treatment liquid flows out of the water-permeable gap 12, and the adsorption efficiency of the coating belt 13 is low. As a further solution of the present invention, extension grooves 29 are opened on both sides of the connecting groove 11, and the ends of the extension grooves 29 pass through the coating roller 9;

[0058] During the process of removing the film on the surface of the solar panel, the treatment liquid flows through the groove 10 to the inside of the connecting groove 11, and then can flow through the water-permeable gap 12 and the extension groove 29 to the surface of the coating roller 9 and contact the coating belt 13, thereby increasing the contact area between the treatment liquid and the coating belt 13 and improving the adsorption efficiency.

[0059] During the process of removing the film from the surface of the solar panel, the sliding shell 16 is pushed out of the storage bin 6 under the pressure of the treatment liquid when inside the storage bin 6. As a further solution of the present invention, an L-shaped limit plate 30 is fixedly connected to the upper end surface of the sliding shell 16. The limit plate 30 is used to limit the sliding shell 16 when the sliding shell 16 moves downward;

[0060] During the process of removing the film on the surface of the solar panel, when the sliding shell 16 moves downward under the pressure of the processing liquid inside the storage bin 6, the limit plate 30 moves to the position of the blocking plate 15 to limit the sliding shell 16, so as to prevent the sliding shell 16 from being pushed into the storage bin 6 under the pressure of the processing liquid, thereby affecting the subsequent processing of the solar panel.

[0061] The present invention also provides another technical solution, a method for processing oil-sealed etched leads of a PCB solid-state battery panel, the specific steps of the method are as follows:

[0062] Step 1: Plan the overall layout of the internal leads according to the panel design requirements and determine the location and direction;

[0063] Step 2: The solar panel is pre-treated by deoxidation and degreasing, and the wet film is covered by silk screen printing. After exposure and development, the nickel-plated area is exposed;

[0064] Step 3: The battery plate is pre-treated before nickel plating. After being immersed in the electrolyte, current is passed through it, and parameters such as current density, temperature, and stirring are controlled to ensure the quality of the coating.

[0065] Step 4: Laminating the dry film on the nickel-plated solar cell board and exposing and developing the gold-plated area;

[0066] Step 5: Immerse the dry film-coated solar panel in an electrolyte containing gold ions. Apply current to reduce and deposit the gold ions at the gold-plating location. The current is conducted through the internal leads to precisely control the gold-plating area.

[0067] Step 6: After the gold plating is completed, use the PCB solid-state battery board sealing oil etching lead processing device to remove the wet and dry films on the board surface. After removing the film, rinse with deionized water and dry;

[0068] Step 7: Apply solder mask ink to the non-lead and non-welding areas of the solar panel to seal the oil. After coating, perform pre-curing treatment. After the ink is initially cured, perform high-temperature curing to completely cure the solder mask layer, enhance insulation and corrosion resistance, and protect the nickel-gold plated lead part from being affected by subsequent processes.

[0069] Step 8: Press the dry film onto the solar panel again, covering all parts except the internal leads. Remove the internal leads by etching. After etching, remove the dry film by stripping it off. Then, rinse thoroughly with deionized water and dry. Check the lead resistance and other parameters to ensure that the circuit performance meets the standards before proceeding to the subsequent testing and assembly stages.
