Technical Field
[0001] The invention belongs to the technical field of electroplating, and in particular relates to a live-in-cylinder electroplating device and process. Background Art
[0002] Circuit board is an indispensable part of electronic equipment, also known as printed circuit board or printed circuit board. It is composed of integrated circuits, quartz oscillators, fine-tuning capacitors and other electronic components. Through specific layout and connection, it realizes the function of the circuit and provides mechanical support for electronic components.
[0003] PCB electroplating refers to the process of depositing a layer of metal film on the surface or internal hole wall of the PCB by electrochemical method. Its main purpose is to enhance the conductivity of the PCB, improve the corrosion resistance and wear resistance, thereby improving the overall performance and reliability of the PCB.
[0004] The current mainstream method of electroplating circuit boards is mainly based on direct current electroplating technology, the core of which is to continuously apply a constant current to the electroplating tank through an external power supply, so that the metal ions in the electrolyte are evenly deposited on the surface of the circuit board serving as the cathode to form a conductive layer.
[0005] Although the above-mentioned method of electroplating a circuit board can electroplate the circuit board, in the specific operation process, when electroplating the circuit board, it is necessary to energize the plating solution in the copper tank, and after the electroplating of the circuit board is completed, during the process of taking out the electroplated circuit board and placing the unplated circuit board into the copper tank, the electrolyte in the copper tank is still energized. Although continuous energization of the electrolyte does not affect the electroplating of the circuit board, it will increase the cost of the circuit board during the electroplating process. Summary of the invention

[0010] Preferably, symmetrically arranged columns are connected to positions of the frame corresponding to the booms close to the movable platform, and the booms are slidably connected to the columns.
[0011] Preferably, a symmetrically arranged clamping plate is connected to one end of the boom close to the movable platform, corresponding to a position of the column close to the boom, and the clamping plate is slidably connected to the column.
[0012] Preferably, a side of the boom close to the column is rotatably connected to a symmetrically arranged first roller, the first roller fits against the inner wall of the column, and the column is provided with symmetrically arranged limiting grooves at positions corresponding to both ends of the first roller, and the ends of the first rollers are slidably connected in the limiting grooves.
[0013] Preferably, the conductive contact head of the belt is located directly below the conductive contact head of the hanger.
[0014] Preferably, a bearing is connected to the outer side of the conductive contact head.
[0015] Preferably, the frame is connected with a slide rail at positions corresponding to the first slide block and the second slide block, and the first slide block and the second slide block are both slidably connected in the slide rail.
[0016] The present invention also provides a live-entry electroplating process, comprising the following steps: S1: Start the oil cylinder, and with the cooperation of the chain, the movable platform descends, and the descending of the movable platform drives the combined hanger and the conductive contact head of the hanger to descend.
[0017] S2: The conductive contact head of the hanger will contact with the conductive contact head of the belt during the descending process. After the conductive contact head of the hanger contacts with the conductive contact head of the belt, a closed circuit will be formed, so that a weak current will be carried by the combined hanger and the circuit board.
[0018] S3: After the conductive contact head of the hanger contacts with the conductive contact head of the belt, the hanging arm and the conductive contact head of the hanger will continue to descend. During the descent, the conductive contact head of the hanger will drive the conductive contact head of the belt to descend synchronously. The descent of the conductive contact head of the belt will drive the first slider to descend. With the cooperation of the wire rope and the guide wheel, the second slider and the counterweight will rise. When the hanging arm drives the combined hanger to descend into the copper tank and is at the lowest point, the circuit board will contact the electroplating liquid in the copper tank.
[0019] S4: Before the electroplating of the circuit board begins, the electric cylinder will push the combined hanger forward to separate the conductive contact head with the conductive contact head of the hanger. After the conductive contact head with the conductive contact head of the hanger is separated, a short circuit will be formed, so that there is no current on the combined hanger and the circuit board.
[0020] S5: With the cooperation of the counterweight, the guide wheel and the wire rope, the counterweight will drive the second slider to descend, and the wire rope will pull the first slider and the conductive contact head up to the initial position.
[0021] Beneficial effects of the present invention: By starting the oil cylinder, the movable platform is lowered with the cooperation of the chain, and the lowering of the movable platform drives the combined hanger and the conductive contact head of the hanger to descend. The conductive contact head of the hanger will contact the conductive contact head with the belt during the descending process. After the conductive contact head of the hanger contacts the conductive contact head with the belt, a closed circuit will be formed, so that the combined hanger and the circuit board will carry a weak current, so that the circuit board will have a current protection layer when entering the copper tank, preventing the electroplating liquid in the copper tank from attacking the chemical copper layer on the circuit board, causing the circuit board hole to be broken, resulting in poor quality of the circuit board, and the current protection layer can protect the circuit board, thereby ensuring the quality of the circuit board.
[0022] After the conductive contact head of the hanger contacts with the conductive contact head with belt, the hanging arm and the conductive contact head of the hanger will continue to descend. During the descent, the conductive contact head of the hanger will drive the conductive contact head with belt to descend synchronously. The descent of the conductive contact head with belt will drive the first slider to descend. With the cooperation of the wire rope and the guide wheel, the second slider and the counterweight will rise. When the hanging arm drives the combined hanger to descend into the copper tank and is at the lowest point, the circuit board will contact the electroplating liquid in the copper tank. Before the electroplating of the circuit board begins, the electric cylinder will push the combined hanger forward to separate the conductive contact head with belt from the conductive contact head of the hanger. After the conductive contact head with belt is separated from the conductive contact head of the hanger, a short circuit will be formed, so that the combined hanger and the circuit board will no longer carry current. When the circuit board needs protection, a weak current will be carried on the circuit board. When the circuit board is moved, the circuit board will no longer carry a weak current. Compared with the method of keeping power on in the copper tank, more costs can be saved.
[0023] Because the second slider is connected to a counterweight, with the cooperation of the counterweight, guide wheel and wire rope, the counterweight will drive the second slider to descend, and the wire rope will pull the first slider and the conductive contact head up to the initial position, thereby preparing for the protection of the next group of circuit boards and continuously electroplating the circuit boards without affecting the electroplating efficiency of the circuit boards.

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] See also Figure 1 As shown, a live-in-cylinder electroplating device comprises a frame 1, in which a symmetrically arranged support frame 11 is provided at a position away from the middle of the frame 1, and the support frame 11 is used to fix the position of a copper groove 12.
[0029] A copper groove 12 is connected inside the support frame 11 and is used for auxiliary electroplating of the circuit board.
[0030] An oil cylinder 13 is provided at a position corresponding to between the two support frames 11 in the frame 1 , and the oil cylinder 13 is used to drive the chain 15 to rotate.
[0031] A movable platform 14 is provided in the frame 1 at a position corresponding to the top of the oil cylinder 13 , and the movable platform 14 is used to drive the boom 16 to rise and fall.
[0032] A chain 15 is provided between the movable platform 14 and the oil cylinder 13 , and the oil cylinder 13 cooperates with the chain 15 to make the movable platform 14 rise and fall.
[0033] Suspension arms 16 are provided above both sides of the movable platform 14 , and the suspension arms 16 are used to lift the combined hanger 3 .
[0034] See also Figure 3 As shown, a side of the boom 16 close to the movable platform 14 is rotatably connected to a second roller 2 , and the second roller 2 is used to assist the movement of the boom 16 and reduce the friction between the boom 16 and the movable platform 14 .
[0035] The movable platform 14 is connected with symmetrically arranged L-shaped plates 21 at the position corresponding to the first roller 19. The second roller 2 is in contact with the L-shaped plates 21. The L-shaped plates 21 are used to support the second roller 2. With the cooperation of the L-shaped plates 21, the second roller 2 and the movable platform 14, the boom 16 can be driven to lift and lower.
[0036] Corresponding to the position where the boom 16 is close to the movable platform 14 inside the frame 1, symmetrically arranged columns 17 are connected. The boom 16 is slidably connected inside the columns 17. Through the cooperation of the columns 17, the position of the boom 16 can be preliminarily limited.
[0037] At one end of the boom 16 close to the movable platform 14, symmetrically arranged engaging plates 18 are connected corresponding to the position where the columns 17 are close to the boom 16. The engaging plates 18 are slidably connected with the columns 17. Through the cooperation of the engaging plates 18, the position of the boom 16 can be limited, so that the boom 16 can only move vertically.
[0038] On one side of the boom 16 close to the columns 17, symmetrically arranged first rollers 19 are rotatably connected. The first rollers 19 are in contact with the inner walls of the columns 17. The first rollers 19 are used to reduce the friction between the boom 16 and the columns 17, so that the boom 16 can lift and lower more smoothly.
[0039] At the positions corresponding to both ends of the first roller 19 on the columns 17, symmetrically arranged limiting grooves 191 are provided. The ends of the first rollers 19 are slidably connected in the limiting grooves 191. Through the cooperation of the first rollers 19 and the limiting grooves 191, the position of the boom 16 can be limited, so that the boom 16 can only move vertically.
[0040] Please refer to Figure 1 - Figure 3 and Figure 6 - Figure 8 As shown, a combined hanger 3 is suspended below one end of the boom 16 far from the columns 17. The combined hanger 3 is used to clamp and fix the circuit board so that the circuit board can be electroplated.
[0041] Above the combined hanger 3, a hanger support square tube 31 is connected. The hanger support square tube 31 is used to support the combined hanger 3 and at the same time assist the hanger conductive contact head 4 to contact with the belt conductive contact head 46, so that the combined hanger 3 has a weak current.
[0042] On the upper surface of the hanger support square tube 31 close to the frame 1, a hanger conductive contact head 4 is connected. The hanger conductive contact head 4 is used to assist the combined hanger 3 to have a weak current.
[0043] Corresponding to the position of the hanger conductive contact head 4 on the frame 1, a support 41 is connected. Inside the support 41, symmetrically arranged guide wheels 42 are rotatably connected. The guide wheels 42 are used to guide the movement of the steel wire rope 43.
[0044] A steel wire rope 43 is slidably connected to the upper inner side of the two guide wheels 42 , and the steel wire rope 43 is used to connect the first slider 44 and the second slider 45 .
[0045] One end of the steel wire rope 43 close to the hanger conductive contact head 4 is connected to a first slider 44, and the first slider 44 close to the hanger conductive contact head 4 is connected to a conductive contact head 46. By lowering the hanger conductive contact head 4 to contact the conductive contact head 46, a weak current can be passed through the circuit board, thereby protecting the circuit board.
[0046] The belt conductive contact head 46 is located directly below the hanger conductive contact head 4. With this arrangement, after the hanger conductive contact head 4 is lowered, it can be ensured that the hanger conductive contact head 4 is in contact with the belt conductive contact head 46.
[0047] A bearing 47 is connected to the outer side of the conductive contact head 46, and the bearing 47 is used to reduce the friction between the conductive contact head 46 and the conductive contact head 4 of the hanger. When the electric cylinder pushes the combined hanger 3 to move the combined hanger 3 horizontally, it can reduce the resistance and make the combined hanger 3 move more smoothly.
[0048] The end of the wire rope 43 away from the conductive contact head 4 of the hanger is connected to the second slider 45, and the side of the second slider 45 away from the frame 1 is connected to a counterweight 48, which is used to lower the second slider 45 and raise the first slider 44 and the conductive contact head 46.
[0049] The frame 1 is connected with a slide rail 49 at the position corresponding to the first slider 44 and the second slider 45. The first slider 44 and the second slider 45 are both slidably connected in the slide rail 49. Through the cooperation of the slide rail 49, the position of the first slider 44 and the second slider 45 can be limited so that the first slider 44 and the second slider 45 can only move vertically, thereby preventing the first slider 44 and the second slider 45 from offset.
[0050] A rectifier 5 is disposed above the frame 1 corresponding to the slide rail 49 , and the rectifier 5 is used to provide current during the electroplating process.
[0051] See also Figure 5 As shown, a cathode carbon brush 6 is connected to the position above the support frame 11 corresponding to the rectifier 5. The cathode carbon brush 6 is used to conduct current to the circuit board during the electroplating process of the circuit board to ensure uniform current distribution.
[0052] An anode titanium mesh 61 is arranged below the cathode carbon brush 6 in the copper groove 12 . The anode titanium mesh 61 is used for conducting electricity, electrolyzing copper powder to generate copper ions, and maintaining uniform current distribution.
[0053] It is worth noting here that the anode titanium mesh 61 is used in the copper tank 12 because the anode titanium mesh 61 will not react with the electroplating solution in the copper tank 12, can remain stable during use, and will not contaminate the electroplating solution, thereby reducing the replacement frequency of the anode titanium mesh 61 during use and reducing the cost of electroplating; during the use of the anode titanium mesh 61, no metal ions and impurities will be precipitated, thereby avoiding contamination of the electroplating solution.
[0054] The cathode of the rectifier 5 is connected to the first slider 44 and the second slider 45 , and the anode of the rectifier 5 is connected to the anode titanium mesh 61 . This arrangement ensures that the circuit board can be protected before entering the copper tank 12 .
[0055] An anode support rod 62 is connected to the position of the copper tank 12 corresponding to the anode titanium mesh 61 . The anode titanium mesh 61 is connected to the anode support rod 62 . The anode support rod 62 is used to fix the position of the anode titanium mesh 61 .
[0056] Working principle: By starting the oil cylinder 13, the movable platform 14 is lowered with the cooperation of the chain 15. The lowering of the movable platform 14 drives the combined hanger 3 and the conductive contact head 4 of the hanger to descend. The conductive contact head 4 of the hanger will contact the conductive contact head 46 with the belt during the descending process. After the conductive contact head 4 of the hanger contacts the conductive contact head 46 with the belt, a closed circuit is formed, so that the combined hanger 3 and the circuit board are charged with a weak current, so that the circuit board will have a current protection layer when entering the copper tank 12, preventing the electroplating liquid in the copper tank 12 from attacking the chemical copper layer on the circuit board, causing the circuit board hole to break, resulting in poor quality of the circuit board. The current protection layer can protect the circuit board, thereby ensuring the quality of the circuit board; After the conductive contact head 4 of the hanger contacts with the conductive contact head 46, the arm 16 and the conductive contact head 4 of the hanger will continue to descend. The conductive contact head 4 of the hanger will drive the conductive contact head 46 to descend synchronously during the descent process. The descent of the conductive contact head 46 will drive the first slider 44 to descend. Under the cooperation of the wire rope 43 and the guide wheel 42, the second slider 45 and the counterweight 48 will be driven to rise. When the arm 16 drives the combined hanger 3 to descend into the copper tank 12 and is at the lowest point, the circuit board will contact the electroplating liquid in the copper tank 12. Before the electroplating of the circuit board begins, the electric cylinder will push the combined hanger 3 forward to separate the conductive contact head 46 from the conductive contact head 4 of the hanger. After the conductive contact head 46 is separated from the conductive contact head 4 of the hanger, a short circuit will be formed, so that the combined hanger 3 and the circuit board will no longer carry current. When the circuit board needs protection, a weak current will be carried on the circuit board. When the circuit board is moved, the circuit board will no longer carry a weak current. Compared with the method of always powering on in the copper tank 12, more costs can be saved. Because the second slider 45 is connected with a counterweight 48, with the cooperation of the counterweight 48, the guide wheel 42 and the wire rope 43, the counterweight 48 will drive the second slider 45 to descend, and the wire rope 43 will pull the first slider 44 and the conductive contact head 46 up to the initial position, thereby preparing for the protection of the next group of circuit boards and continuously electroplating the circuit boards without affecting the electroplating efficiency of the circuit boards.
[0057] A live-in-tank electroplating process comprises the following steps: S1: Start the oil cylinder 13, and with the cooperation of the chain 15, the movable platform 14 is lowered, and the lowering of the movable platform 14 drives the combined hanger 3 and the hanger conductive contact head 4 to descend.
[0058] S2: The conductive contact head 4 of the hanger will contact the conductive contact head 46 during the descent process. After the conductive contact head 4 of the hanger contacts the conductive contact head 46, a closed circuit will be formed, so that a weak current will be carried by the combined hanger 3 and the circuit board.
[0059] S3: After the conductive contact head 4 of the hanger contacts with the conductive contact head 46, the arm 16 and the conductive contact head 4 of the hanger will continue to descend. During the descent, the conductive contact head 4 of the hanger will drive the conductive contact head 46 to descend synchronously. The descent of the conductive contact head 46 will drive the first slider 44 to descend. With the cooperation of the wire rope 43 and the guide wheel 42, the second slider 45 and the counterweight 48 will be driven to rise. When the arm 16 drives the combined hanger 3 to descend into the copper tank 12 and is at the lowest point, the circuit board will contact the electroplating liquid in the copper tank 12.
[0060] S4: Before the electroplating of the circuit board begins, the electric cylinder will push the combined hanger 3 forward to separate the conductive contact head 46 from the hanger conductive contact head 4. After the conductive contact head 46 is separated from the hanger conductive contact head 4, a short circuit will be formed, so that there is no current on the combined hanger 3 and the circuit board.
[0061] S5: With the cooperation of the counterweight 48, the guide wheel 42 and the wire rope 43, the counterweight 48 will drive the second slider 45 to descend, and the wire rope 43 will pull the first slider 44 and the conductive contact head 46 up to the initial position.

After the conductive contact head (4) of the hanger comes into contact with the conductive contact head (46), a closed circuit is formed, so that a weak current is carried by the combined hanger (3) and the circuit board; S3: After the conductive contact head (4) of the hanger contacts the conductive contact head (46), the hanging arm (16) and the conductive contact head (4) of the hanger continue to descend. During the descent process, the conductive contact head (4) of the hanger drives the conductive contact head (46) to descend synchronously. The descent of the conductive contact head (46) drives the first slider (44) to descend. With the cooperation of the steel wire rope (43) and the guide wheel (42), the second slider (45) and the counterweight (48) are driven to rise. When the hanging arm (16) drives the combined hanger (3) to descend into the copper tank (12) and is at the lowest point, the circuit board contacts the electroplating solution in the copper tank (12); S4: Before the electroplating of the circuit board begins, the electric cylinder pushes the combined hanger (3) forward, so that the conductive contact head (46) is separated from the conductive contact head (4) of the hanger. After the conductive contact head (46) is separated from the conductive contact head (4) of the hanger, a circuit is formed, so that the combined hanger (3) and the circuit board no longer carry current; S5: With the cooperation of the counterweight (48), the guide wheel (42) and the steel wire rope (43), the counterweight (48) drives the second slider (45) to descend, and the steel wire rope (43) pulls the first slider (44) and the conductive contact head (46) to rise to the initial position.
