Description

Technical Field

[0001] This invention belongs to the technical field of circuit board manufacturing equipment, and particularly relates to a chemical copper plating treatment device for circuit board production. Background Technology

[0002] With the rapid development of electronic information technology, circuit boards, as the core carrier for electrical connections of electronic components, have been widely used in fields such as communications, consumer electronics, automotive electronics, and industrial control. Circuit boards are mainly divided into rigid circuit boards and flexible circuit boards. In the manufacturing process of circuit boards, through holes after drilling need to undergo copper plating to form a continuous conductive layer on the insulating hole wall, thereby realizing interlayer electrical interconnection.

[0003] In existing copper plating processes, flexible circuit boards are typically held in rigid fixtures and then immersed in copper plating solution for processing. However, during the immersion process, due to the high flow resistance of the copper plating solution in the micro-holes with high aspect ratio, air bubbles are easily trapped on the hole walls and are difficult to remove effectively. This results in uneven copper plating layer thickness and incomplete coverage in the holes, which seriously affects the electrical interconnection reliability of the final circuit.

[0004] Therefore, there is a particular need for a chemical copper plating treatment device for circuit board production to solve the above problems. Summary of the Invention

[0005] To overcome the shortcomings of existing copper plating processes, such as air bubble retention and uneven copper plating in high aspect ratio micropores due to rigid clamping and static immersion, which affect electrical reliability, this invention provides a chemical copper plating treatment device for circuit board production.

The two ends of the spring are respectively connected to the connecting frame and the sliding frame. A connecting rod is fixedly connected to the rear side of the sliding frame. Symmetrical components are mounted on the sliding frame. Two fixed plates are fixedly connected, and a movable plate is slidably mounted on the fixed plates. A clamping plate is fixedly mounted at the lower end of the movable plate. The clamping plate and the limit frame on the same side form a sliding fit. A dual-axis motor is installed on the upper part of the lifting plate. The dual-axis motor is electrically connected to the controller. Both output shafts of the dual-axis motor are fixedly connected to lead screws. The dual-axis motor and lead screws are covered by a housing. A sliding plate is threaded through the lead screw. The sliding plate maintains sliding contact with the lifting plate. A connecting plate is fixedly connected to the upper part of the sliding plate. A sliding groove is opened on the connecting plate. The connecting rod slides into both sliding grooves at the same time.

[0009] Furthermore, it also includes a movable shell, a support plate, a guide rod three, a spring three, a gear, an eccentric plate, a rack, a lower limit cylinder, and an upper limit cylinder. The movable shell is slidably arranged at the lower part of the vertical plate. The guide rod three is fixedly arranged inside the movable shell. The support plate slides through the guide rod three. The upper end of the guide rod three is fitted with a spring three. The two ends of the spring three are respectively connected to the inner wall of the movable shell and the support plate. The lower limit cylinder and the upper limit cylinder are respectively fixed to the movable shell and the support plate. The gear is rotatably arranged on the rear side of the movable shell. The eccentric plate is fixedly connected to the gear. The rack is fixedly connected to the rear side of the upper part of the frame. The rack meshes with the gear. The eccentric plate is initially in a vertical position. The protruding end pushes the support plate upward. The spring three is initially in a compressed state.

[0010] Furthermore, liquid passage holes are provided on the walls of both the lower and upper limit cylinders.

[0011] Furthermore, it also includes piston cylinder one, piston cylinder two, piston rod one, piston block one, fixing frame, piston rod two, and piston block two.

[0012] Furthermore, it also includes a drain valve, which is installed on the rear side of the lower part of the frame.

[0013] Furthermore, it also includes a guide rod, which is fixedly attached to the fixed plate and passes horizontally through the corresponding movable plate.

[0014] Furthermore, it also includes a guide plate, which is fixedly attached side by side to the rear side of the housing, and the guide plate passes horizontally through the corresponding sliding plate.

[0015] The beneficial effects are as follows: 1. Through the synergistic action of the wave plate, guide rod four, slide plate, spring four, sliding block and disturbance rod, periodic mechanical disturbance is applied to the flexible circuit board during the lifting and lowering immersion process, so that the flexible circuit board produces controllable undulating deformation, effectively breaking the boundary layer of copper plating liquid on the hole wall and surface, promoting the flow and renewal of copper plating liquid, and significantly improving the uniformity and coverage integrity of the copper plating layer.

[0016] 2. By setting up a movable shell, support plate, guide rod three, spring three, gear, eccentric plate, rack, lower limit cylinder and upper limit cylinder, flexible positioning of the middle part of the flexible circuit board is achieved. During clamping, a large gap is maintained to facilitate operation. During operation, it automatically clamps, effectively preventing the middle part of the flexible circuit board from sagging due to its own weight, and ensuring positional stability during immersion.

[0017] 3. By cooperating with piston cylinder one, piston cylinder two, piston rod one, piston block one, fixing frame, piston rod two and piston block two, the clamping action and the sinking action of the middle part of the flexible circuit board are mechanically coupled. Without the need for an additional drive source, the clamping of both ends of the flexible circuit board and the precise immersion of the middle area in copper liquid can be completed simultaneously, improving the reliability of the operation.

[0037] Example: A chemical copper plating treatment apparatus for circuit board production, such as... Figures 1-5 , Figures 7-10 and Figures 16-18As shown, the device includes a frame 1, a controller 101, a support frame 3, an electric slide rail 4, an electric slider 5, a lifting plate 6, a housing 61, and a vertical plate 62. Two support frames 3 are bolted to the upper part of the frame 1. An electric slide rail 4 is bolted to the upper end of each support frame 3. An electric slider 5 slides on the electric slide rail 4. A lifting plate 6 is fixedly connected between the two electric sliders 5. The housing 61 is bolted to the upper part of the lifting plate 6. The controller 101 is bolted to the front of the housing 61. The controller 101 is a programmable logic controller (PLC), model Huichuan Easy. 521-24T4DT, the electric slide rail 4 and electric slider 5 are both electrically connected to the controller 101. A vertical plate 62 is fixedly installed on the rear side of the lifting plate 6. It also includes a wave plate 19, four guide rods 20, a sliding plate 21, four springs 22, a sliding block 24, and a disturbance rod 25. Two wave plates 19 are fixedly connected to the rear side of the upper part of the frame 1. Four guide rods 20 are fixedly connected to the rear side of the vertical plate 62. A sliding plate 21 slides between every two vertically aligned guide rods 20. A spring 22 is sleeved on the guide rods 20. The front and rear ends of the spring 22 are respectively connected to the vertical plate 62 and the sliding plate 21 to provide a return force for the sliding plate 21. A limit groove 23 is opened at the lower end of the sliding plate 21. A sliding block 24 is slidably arranged inside the 23. Two disturbance rods 25 are slidably arranged side by side at the lower part of the vertical plate 62. The sliding block 24 is fixedly connected to the rear end of the disturbance rod 25 on the same side. The upper end of the slide plate 21 is provided with a protrusion. The protrusion initially keeps in contact with the arc surface at the highest point of the corrugated plate 19. When the vertical plate 62 drives the slide plate 21 to move downward, the protrusion slides along the continuous undulating contour of the corrugated plate 19 and contacts the other arc surfaces in turn, thereby pushing the slide plate 21 to produce periodic back-and-forth reciprocating motion. During this process, the sliding block 24 slides up and down along the limiting groove 23, driving the disturbance rods 25 to move up and down synchronously. The disturbance rods 25 act on the surface of the flexible circuit board, causing the flexible circuit board to produce controllable undulating deformation.

[0038] like Figures 1-6 , Figures 8-10 and Figure 17As shown, it also includes a limit frame 7, a movable plate 71, a clamping plate 72, a connecting frame 8, a sliding frame 9, a spring 91, a guide rod 92, a fixed plate 93, a connecting rod 10, a dual-axis motor 11, a lead screw 12, a sliding plate 13, and a connecting plate 14. Two limit frames 7 are slidably arranged side by side at the lower part of the vertical plate 62. A connecting frame 8 is fixedly installed at the center of the rear side of the lifting plate 6. A guide rod 92 is fixedly connected inside the connecting frame 8. The sliding frame 9 slides through the guide rod 92. A spring 91 is sleeved on the upper end of the guide rod 92. The upper and lower ends of the spring 91 are connected to the connecting frame 8 and the sliding frame 9, respectively, providing a return spring force for the sliding frame 9. A connecting rod 10 is fixedly connected to the rear side of the sliding frame 9. A connecting rod 10 is fixedly connected to the sliding frame 9. Two fixed plates 93 are connected, and a movable plate 71 is slidably mounted on the fixed plate 93. A clamping plate 72 is fixedly mounted on the lower end of the movable plate 71. The clamping plate 72 and the limit frame 7 on the same side form a sliding fit. A dual-axis motor 11 is bolted to the upper part of the lifting plate 6. The dual-axis motor 11 is electrically connected to the controller 101. Both output shafts of the dual-axis motor 11 are fixedly connected to lead screws 12 through couplings. The dual-axis motor 11 and the lead screws 12 are both covered by the housing 61. A sliding plate 13 is threaded through the lead screw 12. The sliding plate 13 maintains sliding contact with the lifting plate 6. A connecting plate 14 is fixedly connected to the upper end of the sliding plate 13. A sliding groove 141 is opened on the connecting plate 14. The connecting rod 10 slides into both sliding grooves 141 at the same time.

[0039] like Figure 1 and Figures 7-15As shown, it also includes a movable shell 15, a support plate 151, a guide rod 152, a spring 153, a gear 16, an eccentric plate 161, a rack 17, a lower limit cylinder 18, and an upper limit cylinder 181. The movable shell 15 is slidably disposed at the lower part of the vertical plate 62. The guide rod 152 is fixedly disposed inside the movable shell 15. The support plate 151 is slidably disposed on the guide rod 152. The spring 153 is sleeved on the upper end of the guide rod 152. The upper and lower ends of the spring 153 are respectively connected to the movable shell 15. The inner wall and the support plate 151 provide a restoring elastic force for the support plate 151. A lower limiting cylinder 18 and an upper limiting cylinder 181 are fixedly connected to the movable shell 15 and the support plate 151, respectively. Liquid passage holes are provided on the walls of both the lower limiting cylinder 18 and the upper limiting cylinder 181, allowing the copper plating solution to pass through them and contact the surface of the flexible circuit board. This ensures reliable positioning of the flexible circuit board while guaranteeing the flow and coverage of the copper plating solution during the copper plating process. A gear 16 is rotatably mounted on the rear side of the cover and movable shell 15. An eccentric plate 161 is fixedly connected to the gear 16. A rack 17 is fixedly connected to the upper rear side of the frame 1. The rack 17 meshes with the gear 16. The eccentric plate 161 is initially in a vertical position, with its protruding end pushing the support plate 151 upward. The spring 153 is initially in a compressed state, thereby raising the upper limit cylinder 181 to its highest position. At this time, the lower limit cylinder 18 and the upper limit cylinder 181 maintain the maximum clamping gap, which facilitates flexible... When the flexible circuit board is installed, as the movable housing 15 moves downward with the lifting action, the gear 16 rolls along the rack 17, causing the eccentric plate 161 to rotate synchronously. As the eccentric plate 161 rotates to the non-pushing phase, the upward force on the support plate 151 is released, and the spring 153 extends under the action of the reset elastic force, pushing the support plate 151 together with the upper limit cylinder 181 to move downward, so that the upper limit cylinder 181 and the lower limit cylinder 18 work together to clamp the flexible circuit board, realizing adaptive and flexible limit clamping.

[0040] like Figure 1 , Figure 11 and Figure 12As shown, it also includes piston cylinder 26, piston cylinder 261, piston rod 262, piston block 2621, fixing bracket 263, piston rod 2631, and piston block 2632. Piston cylinder 261 is fixedly mounted on the upper rear side of the housing 61. Two piston cylinders 261 are fixedly connected to the upper end of piston cylinder 261. Piston rod 262 slides through the piston cylinders 261. Piston block 2621 is fixedly connected to the ends of the two piston rods 262 that are close to each other. 621 forms a sliding seal with the piston cylinder 261. The other ends of the two piston rods 262 are respectively fixedly connected to two sliding plates 13. The piston rod 2631 slides through the piston cylinder 26. The piston block 2632 is fixedly provided at the upper end of the piston rod 2631. The piston block 2632 forms a sliding seal with the piston cylinder 26. The lower end of the piston rod 2631 is fixedly connected to the fixing frame 263, which is fixedly connected to the movable shell 15.

[0041] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, it also includes a drain valve 2. The drain valve 2 is bolted to the lower rear side of the frame 1 to facilitate the discharge of copper plating solution inside the frame 1.

[0042] like Figure 2 , Figure 5 and Figure 6 As shown, it also includes a guide rod 73, which is fixedly connected to the fixed plate 93. The guide rod 73 passes horizontally through the corresponding moving plate 71 to provide precise guidance for the moving plate 71.

[0043] like Figure 9 As shown, it also includes a guide plate 131. The guide plate 131 is fixedly connected side by side to the rear side of the housing 61. The guide plate 131 passes horizontally through the corresponding sliding plate 13, further improving the stability of the movement of the sliding plate 13.

[0044] In use, the flexible circuit board is first placed between the lower limiting cylinder 18 and the upper limiting cylinder 181. At this time, the eccentric plate 161 is in the pushing phase, and the protruding end pushes the support plate 151 upward, compressing the spring 153. The upper limiting cylinder 181 is raised to the highest position, and the maximum clamping gap is maintained between the upper limiting cylinder 181 and the lower limiting cylinder 18 to facilitate the insertion of the flexible circuit board. At the same time, the two ends of the flexible circuit board are inserted into the limiting frames 7 on both sides. Then, the dual-axis motor 11 is started by the controller 101, and the lead screws 12 on both sides rotate clockwise synchronously, driving the two sliding plates 13 to move inward. The connecting plate 14 moves inward accordingly, and the connecting rod 10 slides along the slide groove 141, driving the sliding frame 9 to move downward along the guide rod 92 and stretching the spring 91. The sliding frame 9 synchronously drives the two fixed plates. 93 moves downward, causing the two moving plates 71 and clamping plates 72 to press down on both ends of the flexible circuit board. During the inward movement of the sliding plate 13, the piston rod 262 is pushed and slides into the piston cylinder 261. The piston block 2621 slides inward along the piston cylinder 261, compressing the gas inside the piston cylinder 261. The gas enters the piston cylinder 26, pushing the piston block 2632 to slide downward along the piston cylinder 26. The piston rod 2631 extends out, causing the fixed frame 263 and the moving shell 15 to move downward synchronously. When the moving shell 15 descends, the gear 16 rolls along the rack 17, causing the lower limit cylinder 18 and the eccentric plate 161 to rotate synchronously. When the eccentric plate 161 rotates to the non-pushing phase, the upward force on the support plate 151 is released, and the spring 153... Under the action of the reset spring, the support plate 151 and the upper limit cylinder 181 extend downwards, so that the upper limit cylinder 181 and the lower limit cylinder 18 work together to flexibly clamp the middle of the flexible circuit board, preventing the middle of the flexible circuit board from sagging due to its own weight during the copper plating process. Then, the two electric slide rails 4 are activated, controlling the two electric sliders 5 to drive the lifting plate 6 to move back and forth downwards and upwards, so that the vertical plate 62 rises and falls synchronously, periodically immersing and lifting the flexible circuit board into and out of the copper plating solution. During the rising and falling process, the vertical plate 62 drives the limit frame 7 and the slide plate 21 to move synchronously. The limit frame 7 pulls the two ends of the flexible circuit board up and down smoothly with the rising and falling action. At the same time, the protrusion at the upper end of the slide plate 21 slides along the continuous undulating contour of the corrugated plate 19. When the protrusion contacts the arc surface of the corrugated plate 19, it pushes the slide plate 21 along the contour of the corrugated plate 19. The guide rod 20 slides forward and compresses the spring 22. When the protrusion disengages from the arc-shaped surface, the spring 22 releases, pushing the slide plate 21 back to its original position. This creates a periodic reciprocating motion of the slide plate 21. This reciprocating motion is transmitted to the sliding block 24 through the limiting groove 23, causing the disturbance rod 25 to move up and down. This motion acts on the surface of the flexible circuit board, causing controllable undulating deformation. This effectively disturbs the boundary layer of the copper plating solution on the hole walls and surface, enhancing the flow and renewal of the copper plating solution, preventing air bubble retention, and improving the uniformity and coverage integrity of the copper plating layer. After the copper plating is completed, the two electric sliders 5 are controlled to drive the lifting plate 6 to rise back to its original position. Then, the dual-axis motor 11 is restarted, controlling the two lead screws 12 to rotate counterclockwise synchronously, driving the two sliding plates 13 to move outward.As the connecting plate 14 moves outward, the connecting rod 10 slides to the initial position of the slide groove 141, causing the sliding frame 9 to reset upward. The spring 91 returns to its original state to assist the sliding frame 9 in resetting. The sliding frame 9 simultaneously drives the two fixed plates 93 and the moving plate 71 to move upward, causing the two clamping plates 72 to release the two ends of the flexible circuit board. At the same time, the sliding plate 13 moves outward, pulling the piston rod 262 outward from the piston cylinder 261. The piston block 2621 slides outward along the piston cylinder 261 to form a negative pressure. The suction piston block 2632 slides upward along the piston cylinder 261. The piston rod 2631 drives the fixed frame 263 and the moving shell 15 to move upward and reset simultaneously. During the upward movement of the vertical plate 62, the gear 16 rolls in the opposite direction along the rack 17, causing the eccentric plate 161 to rotate back to the pushing phase. The support plate 151 is pushed upward again and the spring 153 is compressed. The upper limit cylinder 181 moves upward and restores the maximum clamping gap with the lower limit cylinder 18. At this time, the flexible circuit board that has completed copper plating can be taken out. ,
