[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1-11 An automatic copper plating wire bonding machine for circuit board processing is shown, comprising an outer frame 1, with multiple cleaning tanks 2 inside the outer frame 1, each containing a cleaning solution. A liquid tank 3 is fixedly connected to one side wall of the cleaning tank 2, containing copper plating solution. A rolling cleaning mechanism 4 is installed inside the cleaning tank 2 to clean the liquid in the cleaning tank 2. An air pressure supply mechanism 5 is installed outside the rolling cleaning mechanism 4 to supply air pressure. A cleaning effect retention mechanism 6 is installed on the side wall of the cleaning tank 2 away from the liquid tank 3 to maintain the cleaning effect of the rolling cleaning mechanism 4. A circulating water mechanism 7 is installed at the top of the cleaning tank 2 to circulate the cleaning solution inside the cleaning tank 2.

[0033] The rolling cleaning mechanism 4 includes two mounting covers 401, which provide mounting positions. An active roller 403 is rotatably connected between the two mounting covers 401. An electric motor 402 is fixedly connected to the outside of one of the mounting covers 401, providing power. The output end of the electric motor 402 is fixedly connected to one end of the active roller 403. A driven roller 404 is rotatably connected inside the cleaning tank 2. A rolling filter belt 405 is sleeved between the active roller 403 and the driven roller 404. The driven roller 404, in conjunction with the active roller 403, can drive the rolling filter belt 405 to rotate. After the circuit board enters the interior of the cleaning tank 2 from the liquid tank 3 using the conveying device, it is cleaned. The water in the cleaning tank 2 is collected into the top of the rolling filter belt 405 using the circulating water mechanism 7. The electric motor 402 is started, and after the electric motor 402 rotates, it can work with the driven roller 404 to drive the rolling filter belt 405 to rotate, thereby using the rolling filter belt 405 to filter and clean the cleaning liquid in the cleaning tank 2.

[0034] The gas supply mechanism 5 includes a gas production cylinder 501, which provides an installation position. The gas production cylinder 501 is externally connected to the outside of one of the mounting covers 401. A piston 502 is slidably connected inside the gas production cylinder 501. The piston 502 can perform air intake and exhaust by moving up and down. A push-pull rod 503 is fixedly connected to the top of the piston 502, which can adjust the piston 502 to move up and down. A drive cover 504 is fixedly connected to the top of the push-pull rod 503. A rotating arm 505 is fixedly connected to one end of the drive roller 403, which can drive the drive cover 504 to move up and down.

One-way valve 2 507 is fixedly connected to the bottom of the outer wall of the gas production cylinder 501. One-way valve 1 506 and one-way valve 2 507 can allow one-way air passage. When the drive roller 403 rotates, it can drive the rotating arm 505 to rotate. The bottom of the rotating arm 505 slides inside the drive cover 504, thereby driving the drive cover 504 to move up and down. When the drive cover 504 moves upward, it can drive the push rod 503 to move upward, which in turn can drive the piston 502 to move upward. At this time, one-way valve 1 506 is closed and one-way valve 2 507 is opened, thereby drawing in air. When the piston 502 moves downward, one-way valve 2 507 closes and one-way valve 1 506 opens, thereby venting the air in the gas production cylinder 501.

[0035] The cleaning effect maintenance mechanism 6 includes an impurity storage box 618, which provides an installation position. One end of the impurity storage box 618 is fixedly connected to the side wall of the cleaning tank 2 away from the liquid tank 3.

An inflation pipe 602 is fixedly connected to one end of the air tank 601, which serves as a connection. One end of the inflation pipe 602 is fixedly connected to the inside of a one-way valve 506. An automatic valve 603 is fixedly connected to the other end of the air tank 601, which can open and close the gas path. The automatic valve 603 is located away from the side wall of the air tank 601. An exhaust pipe 604 is fixedly connected to one end, enabling communication. One mounting cover 401 has a sliding groove 614 inside, with a sliding block 615 slidably connected inside. A mounting box 605 is fixedly connected to one side wall of the sliding block 615, providing an installation position. The sliding groove 614 provides space for the sliding block 615 to move up and down, allowing the mounting box 605 to move vertically. An impeller 606 is rotatably connected inside the mounting box 605, rotating under the flow of gas. Both mounting covers 401 have movable grooves 607 inside, with sliding blocks 608 slidably connected inside. The movable grooves 607 provide... The sliding blocks 608 have space for vertical movement. A cleaning roller 609 is rotatably connected between the two sliding blocks 608. The rotation of the cleaning roller 609 can clean the rolling filter belt 405. One end of the cleaning roller 609 is fixedly connected to the middle of the impeller 606. A fixing box 610 is fixedly connected to the bottom inner side of the mounting cover 401. The fixing box 610 provides the installation position. A push spring 611 is set inside the fixing box 610. A limit plate 612 is slidably connected inside the fixing box 610. The limit plate 612 has a limiting function. A movable plate 613 is fixedly connected to the top of the limit plate 612. The movable plate 613 can provide the connection position. The tops of the two movable plates 613 are respectively rotatably connected to the two ends of the cleaning roller 609. The two mounting covers 401 are... A jet pipe 616 is fixedly connected to the mounting box 605, which can spray gas to clear the rolling filter belt 405. An exhaust pipe 617 is fixedly connected to one end of the jet pipe 616, serving a connecting function. The end of the exhaust pipe 617 away from the jet pipe 616 is fixedly connected to the top of the mounting box 605. An exhaust pipe 604 away from the gas tank 601 is fixedly connected to the bottom of the mounting box 605. A guide plate 619 is fixedly connected inside the impurity storage box 618. An automatic exhaust valve 620 is fixedly connected to one end of the gas tank 601. The guide plate 619 is located at the bottom of the cleaning roller 609, which contacts the rolling filter belt 405. One end of the push spring 611 is fixedly connected to the bottom of the mounting box 610.The other end of the push spring 611 is fixedly connected to the bottom of the limiting plate 612, the movable plate 613 passes through the top of the fixed box 610, and the jet pipe 616 is set inside the rolling filter belt 405;

[0036] Air from the gas production cylinder 501 enters the gas tank 601 through the inflation pipe 602, increasing the internal pressure. This opens the automatic valve 603, allowing air to enter the mounting box 605 through the outlet pipe 604. This, in turn, drives the impeller 606 to rotate. The rotating impeller 606 then drives the cleaning roller 609 to rotate, cleaning the outer surface of the rolling filter belt 405 and preventing blockage. Air entering the mounting box 605... Gas enters the interior of the jet pipe 616 through the exhaust pipe 617, thereby ejecting gas to further clean and unclog the impurities on the rolling filter belt 405. At the same time, the push spring 611 can use its own reaction force to exert an upward force on the limit plate 612, and transmit the force to the movable plate 613, thereby transmitting the force to the cleaning roller 609, thus exerting an upward force on the cleaning roller 609, causing the cleaning roller 609 to press against the outer surface of the rolling filter belt 405, thereby cleaning the rolling filter belt 405.

[0037] The circulating water mechanism 7 includes a top plate 710, which provides an installation position and prevents liquid splashing. The bottom of the top plate 710 is fixedly connected to the top of the cleaning tank 2. A liquid storage tank 701 is fixedly connected to the top of the top plate 710. The liquid storage tank 701 can temporarily store liquid. A waterproof vent valve 702 is fixedly connected to one end of the liquid storage tank 701. The waterproof vent valve 702 can only allow air to enter and cannot allow liquid to exit. A vent pipe 703 is fixedly connected to the end of the waterproof vent valve 702 away from the liquid storage tank 701. The vent pipe 703 can extract air. One end of the liquid storage tank 701 is fixedly connected to... There is a control valve 704, which controls the opening and closing of the liquid flow channel. A water pipe 705 is fixedly connected to the end of the control valve 704 away from the liquid storage tank 701, allowing liquid to flow into it. A water outlet pipe 706 is fixedly connected to the inner side of the top plate 710, allowing liquid to be discharged. The bottom end of the water pipe 705 is fixedly connected to one end of the water outlet pipe 706. A solenoid valve 707 is fixedly connected to the end of the liquid storage tank 701 away from the control valve 704, allowing the liquid channel to be opened and closed. A pump is fixedly connected inside the solenoid valve 707. Water pipe 708 and pumping pipe 708 allow liquid from the cleaning tank 2 to flow into the storage tank 701. The bottom end of pumping pipe 708 is fixedly connected to the bottom of the cleaning tank 2. A pressure relief valve 709 is fixedly connected to the top of the storage tank 701. The pressure relief valve 709 can be opened when the air pressure inside the storage tank 701 is too low, or when the control valve 704 is opened, thus facilitating the flow of liquid from the storage tank 701 into the cleaning tank 2. The bottom end of vent pipe 703 is fixedly connected to the inside of one-way valve 507. When the waterproof vent valve 702 is opened, the air pressure... The supply mechanism 5 extracts gas from the storage tank 701 through the vent pipe 703, thereby removing air from the storage tank 701 and creating negative pressure inside the storage tank 701. This opens the solenoid valve 707, allowing liquid from the cleaning tank 2 to be drawn into the storage tank 701 through the water suction pipe 708. At this time, the storage tank 701 stores liquid. The control valve 704 is then opened, allowing the liquid to be discharged through the water pipe 705 and into the water outlet pipe 706. The liquid is then discharged through the water outlet pipe 706, allowing it to be filtered and cleaned by the rolling filter belt 405.

[0038] Working principle: After the circuit board enters the cleaning tank 2 from the liquid pool 3 using the conveying device, it is cleaned. The water in the cleaning tank 2 is collected into the top of the rolling filter belt 405 by the circulating water mechanism 7. The motor 402 is started. After the motor 402 rotates, it can work with the driven roller 404 to drive the rolling filter belt 405 to rotate, so that the cleaning liquid in the cleaning tank 2 can be filtered and cleaned by the rolling filter belt 405.

[0039] When the drive roller 403 rotates, it drives the rotating arm 505 to rotate. The bottom of the rotating arm 505 slides inside the drive cover 504, thereby driving the drive cover 504 to move up and down. When the drive cover 504 moves upward, it drives the push rod 503 to move upward, which in turn drives the piston 502 to move upward. At this time, the one-way valve 1 506 closes and the one-way valve 2 507 opens, thereby drawing in air. When the piston 502 moves downward, the one-way valve 2 507 closes and the one-way valve 1 506 opens, thereby venting the air in the gas production cylinder 501.

[0040] Air from the gas production cylinder 501 enters the gas tank 601 through the inflation pipe 602, increasing the internal pressure. This opens the automatic valve 603, allowing air to enter the mounting box 605 through the outlet pipe 604. This, in turn, drives the impeller 606 to rotate. The rotating impeller 606 then drives the cleaning roller 609 to rotate, cleaning the outer surface of the rolling filter belt 405 and preventing blockage. Air entering the mounting box 605... Gas enters the interior of the jet pipe 616 through the exhaust pipe 617, thereby ejecting gas to further clean and unclog the impurities on the rolling filter belt 405. At the same time, the push spring 611 can use its own reaction force to exert an upward force on the limit plate 612 and transmit the force to the movable plate 613, thereby transmitting the force to the cleaning roller 609, thus exerting an upward force on the cleaning roller 609 and causing the cleaning roller 609 to press against the outer surface of the rolling filter belt 405, thereby cleaning the rolling filter belt 405.

[0041] When the waterproof vent valve 702 is opened, the air pressure supply mechanism 5 extracts the gas from the liquid storage tank 701 through the vent pipe 703, thereby removing the air from the liquid storage tank 701 and creating a negative pressure inside the liquid storage tank 701. The solenoid valve 707 is then opened, allowing the liquid in the cleaning pool 2 to be drawn into the liquid storage tank 701 through the water suction pipe 708. At this time, the liquid storage tank 701 stores liquid. The control valve 704 is then opened, allowing the liquid to be discharged through the water flow pipe 705 and into the water outlet pipe 706. The liquid is then discharged through the water outlet pipe 706, allowing it to be filtered and cleaned by the rolling filter belt 405.
