Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and specifically relates to a surface treatment device for circuit board processing. Background Art

[0002] In the field of circuit board processing, surface treatment is a crucial link, which plays a decisive role in the performance and quality of circuit boards. Currently, common circuit board surface treatment technologies mainly include processes such as electroless copper plating and immersion plating.

[0003] However, when the traditional circuit board body undergoes the electroless copper plating process, the copper plate of the circuit board needs to go through multiple immersion plating tanks for chemical reactions. Chemical solutions are likely to remain on the circuit board, affecting the quality of subsequent processes. In the multi-immersion plating tank process, the circuit board is likely to carry chemical solutions to other tanks during transfer, resulting in an imbalance in the solution composition and affecting the consistency of the electroless copper plating effect. Existing equipment lacks an effective anti-pollution design, increasing the difficulty of process control; for circuit boards of different sizes, special fixtures need to be frequently replaced or the hanging basket structure needs to be adjusted. The equipment adjustment is complex and time-consuming, and it is difficult to meet the production requirements of multi-variety and small batches. Although some devices can be adjusted, they lack a reliable fixing mechanism, easily resulting in circuit board displacement or detachment; existing equipment often relies on manual loading and unloading and transfer of circuit boards, with limited processing speed and prone to production interruptions due to operation errors.

Detailed implementation manners

[0037] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0038] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 and Figure 11 As shown in

[0039] a surface treatment device for circuit board processing according to the present invention includes a copper deposition tank 1, a walking structure 2 arranged on both sides of the copper deposition tank 1, a control box 3 arranged on the walking structure 2, a lifting structure 4 arranged on the control box 3, a drying structure 5 arranged on the lifting structure 4, a clamping structure 6 arranged on the lifting structure 4, a feeding structure 9 arranged at the end of the copper deposition tank 1, a hanging basket structure 7 arranged on the feeding structure 9, an adjusting structure 8 arranged on the hanging basket structure 7, a conveying structure 10 arranged on one side of the feeding structure 9, and a circuit board body 11 placed on the conveying structure 10 and the hanging basket structure 7;

[0040] The lifting structure 4 includes a first screw rod 401 and a lifting plate 402 threadedly connected to the first screw rod 401. The first screw rod 402 is rotatably connected inside the control box 3, and the lifting plate 402 is slidably connected to the control box 3;

[0041] A first motor 403 is fixedly connected to the control box 3, and the output end of the first motor 403 is fixedly connected to a first screw rod 401; two guide rods 405 are fixedly connected inside the control box 3, the lifting plate 402 is slidably connected to the guide rods 405, and a U-shaped mounting bracket 404 is fixedly connected to the bottom end of the lifting plate 402; a T-shaped slider 503 is fixedly connected to each side of the air box 502, and the slider 503 is slidably connected to the mounting frame 501; the control walking structure 2 is moved directly above the copper immersion tank 1, the first motor 403 of the lifting structure 4 is started, the first screw rod 401 is driven to drive the lifting plate 402 to descend, and the hanging basket structure 7 is immersed in the copper immersion tank 1. The immersion plating time is set according to the process requirements. After completion, the lifting structure 4 automatically lifts the hanging basket structure 7 to the initial height. When the circuit board body 11 is immersed and plated in one immersion plating tank, the lifting structure 4 drives the hanging basket structure 7 to rise, and at the same time, the blower 505 is started. Air flow enters the air box 502 through the connecting pipe 506. During the lifting process of the air box 502, the driving wheel 509 rolls along the wavy driving plate 507, thereby driving the connecting rod 508 to move. The connecting rod 508 drives the air box 502 to slide. When the driving wheel 509 moves to the peak of the wavy driving plate 507, the air box 502 drives the fixed rod 510 to move, thereby compressing the first spring 513. When the lifting plate 402 continues to rise, the first spring 513 resets, thereby driving the air box 502 to reset, and the driving wheel 509 then rolls to the trough of the driving plate 507. In this way, the air box 502 swings back and forth on the mounting frame 501, realizing uniform air drying. When the blowing angle needs to be adjusted, the air guiding piece 504 can be manually toggled when the circuit board body 11 is loaded, so that the blowing angle is better, improving the air drying effect and preventing the chemical solution inside one immersion plating tank from being carried into the inside of another immersion plating tank.

[0042] Specifically, such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14As shown in the figure, the clamping structure 6 includes a drive shaft 601 and a second motor 602.

A connecting bar 604 is fixedly connected between the two first clamping plates 603. A hydraulic rod 605 is fixedly connected to the connecting bar 604. The telescopic end of the hydraulic rod 605 is fixedly connected to a fixing bar 606. Two sliding bars 607 are fixedly connected to the fixing bar 606. The sliding bars 607 are slidably connected to the first clamping plates 603. The end of the sliding bar 607 is fixedly connected to a second clamping plate 608; the middle cross-sections of the first clamping plate 603 and the second clamping plate 608 are both arc-shaped structures, and rubber pads 609 are fixedly connected to the bottom parts of the first clamping plate 603 and the second clamping plate 608;

[0043] The hanging basket structure 7 includes a hanging basket rod 701 and positioning columns 702. The hanging basket rod 701 is clamped between the first clamping plate 603 and the second clamping plate 608. Two groups of positioning columns 702 are fixedly connected to the hanging basket rod 701. Two groups of positioning holes 703 are provided on the second clamping plate 608. The positioning columns 702 are inserted into the positioning holes 703. A connecting fence 704 is fixedly connected to each end of the hanging basket rod 701. The bottom ends of the two connecting fences 704 are fixedly connected to a hanging basket top frame 705. A plurality of telescopic rods 706 are fixedly connected to the bottom end of the hanging basket top frame 705. The bottom ends of the plurality of telescopic rods 706 are fixedly connected to a hanging basket bottom frame 707. A plurality of guide shafts 708 are rotatably connected to the hanging basket top frame 705. A plurality of guide columns 709 are fixedly connected to the hanging basket bottom frame 707. A moving bar 710 is slidably connected to the plurality of guide columns 709. A partition bar 711 is fixedly connected to the moving bar 710. Two other partition bars 711 are fixedly connected to the hanging basket bottom frame 707;

[0044] The adjustment structure 8 includes four telescopic bars 801 and four mounting bars 802. Two telescopic bars 801 are fixedly connected to each of the bottom ends on both sides of the hanging basket top frame 705, and two mounting bars 802 are fixedly connected to each of the top ends on both sides of the hanging basket bottom frame 707. The telescopic bars 801 are slidably connected to the mounting bars 802. Two pressing blocks 803 are symmetrically and slidably connected to the hanging basket top frame 705. A U-shaped slide plate 804 is fixedly connected to the pressing block 803. The slide plate 804 is slidably connected to the hanging basket top frame 705 and is also slidably connected to the telescopic bars 801. Two clamping blocks 805 are fixedly connected to the slide plate 804. A linearly arranged card slot 806 is provided on each mounting bar 802. The clamping blocks 805 are engaged with the card slots 806. A fixed shaft 807 is fixedly connected to the inside of the hanging basket top frame 705. The slide plate 804 is slidably connected to the fixed shaft 807. A second spring 808 is sleeved outside the fixed shaft 807. Two ends of the second spring 808 are respectively fixedly connected to the slide plate 804 and the hanging basket top frame 705. A second screw rod 809 is rotatably connected to the hanging basket bottom frame 707. The second screw rod 809 is threadedly connected to two moving bars 710, and the thread directions at both ends of the second screw rod 809 are opposite. When it is necessary to adjust the distance between the hanging basket top frame 705 and the hanging basket bottom frame 707, the two pressing blocks 803 on the hanging basket top frame 705 are symmetrically pressed by hand. The pressing blocks 803 drive the slide plate 804 fixedly connected thereto to slide on the hanging basket top frame 705. At the same time, the slide plate 804 slides along the fixed shaft 807 and compresses the second spring 808, so that the clamping blocks 805 on the slide plate 804 disengage from the card slots 806 on the mounting bars 802. At this time, the telescopic bars 801 at the bottom ends on both sides of the hanging basket top frame 705 can slide relative to the mounting bars 802 at the top ends on both sides of the hanging basket bottom frame 707. After adjusting the height of the hanging basket according to actual requirements, the pressing blocks 803 are released. Under the elastic force of the second spring 808, the slide plate 804 drives the clamping blocks 805 to reset and re-engage into the corresponding card slots 806 to fix the adjusted height to adapt to the placement requirements of circuit boards of different sizes. Rotate the second screw rod 809 on the hanging basket bottom frame 707. Since the thread directions at both ends of the second screw rod 809 are opposite and it is threadedly connected to the two moving bars 710, when the second screw rod 809 rotates, the two moving bars 710 will slide in opposite directions along a plurality of guiding columns 709, and the partition bars 711 fixedly connected to the moving bars 710 will move accordingly, thereby changing the distance between the partition bars 711 to adapt to the partitioned placement of circuit boards of different sizes, ensuring that the circuit boards remain relatively independent during the processing and avoiding mutual collision.

[0045] Specifically, such as Figure 1 , Figure 3 , Figure 7 , Figure 8 , Figure 10 and Figure 12As shown in the figure, the feeding structure 9 includes a bottom plate 901 and slide rails 902. The bottom plate 901 is provided on the open space at one end of the copper deposition tank 1. Two slide rails 902 are fixedly connected to the bottom plate 901. Two sliding sleeves 903 are fixedly connected to each slide rail 902. A sliding frame 904 is fixedly connected to the four sliding sleeves 903. The bottom frame 707 of the hanging basket is inserted into the sliding frame 904. A fixing plate 905 is fixedly connected to the bottom plate 901. Two hydraulic cylinders 906 are fixedly connected to the fixing plate 905. The telescopic end of the hydraulic cylinder 906 is fixedly connected to the sliding frame 904. When it is necessary to clamp the hanging basket rod 701 of the hanging basket structure 7, keep the first clamping plate 603 and the second clamping plate 608 in the vertical state, and clamp the hanging basket rod 701 through the arc-shaped parts of the first clamping plate 603 and the second clamping plate 608. When clamping, only need to start the hydraulic rod 605. The hydraulic rod 605 pushes the fixing strip 606, drives the second clamping plate 608 to close through the sliding strip 607, and clamps the hanging basket rod 701. The positioning column 702 provided on the hanging basket rod 701 cooperates with the positioning hole 703 on the second clamping plate 608, improving the stability of the clamping structure 6 clamping the hanging basket structure 7. When it is necessary to transfer the circuit board body 11 on the conveying structure 10 to the hanging basket structure 7, the clamping effect of the first clamping plate 603 and the second clamping plate 608 on the hanging basket rod 701 can be released first, and then the clamping structure 6 is lifted by the lifting structure, so that the hanging basket rod 701 will not affect the rotation of the first clamping plate 603 and the second clamping plate 608. Then start the second motor 602, and the second motor 602 drives the driving shaft 601 to rotate 90 degrees, so that the first clamping plate 603 and the second clamping plate 608 are in the horizontal state. Then start the hydraulic rod 605, and the hydraulic rod 605 contracts to drive the fixing strip 606 to move, and then drives the sliding strip 607 to slide, driving the second clamping plate 608 to open. Then move the position of the control box 3 through the traveling structure 2, so that the first clamping plate 603 and the second clamping plate 608 are located on the upper and lower sides of the circuit board body 11 on the conveying structure 10. Then extend the hydraulic rod 605, and then drive the second clamping plate 608 to reset and clamp the circuit board body 11. The setting of the rubber pad 609 improves the clamping stability and at the same time avoids damage to the circuit board surface. Then start the lifting structure 4 to lift the clamping structure 6, and then drive the horizontal circuit board body 11 to rise. After rising to a suitable height, start the second motor 602, and then drive the driving shaft 601 to rotate, driving the first clamping plate 603 and the second clamping plate 608 to rotate to the vertical state. At this time, the clamped circuit board body 11 is also in the vertical state and is directly above the hanging basket structure 7. Then start the lifting structure 4 to make the circuit board body 11 descend. After being stably guided by the guide shaft 708, it is inserted into the separation groove on the separation strip 711. When the lifting of a pair of circuit board bodies 11 is completed, the conveying structure 10 continues to convey the circuit board bodies 11, and at the same time the clamping structure 6 releases the clamping effect on the already fed circuit board bodies 11, and then the lifting structure 4 drives the clamping structure to rise.The clamping structure 6 continues to clamp the circuit board body 11 on the conveying structure 10 and send it to the hanging basket structure 7. When a partition slot on the partition bar 711 is occupied, at this time, the hydraulic cylinder 906 in the feeding structure 9 contracts, driving the sliding frame 904 to move. The sliding frame 904 drives the hanging basket bottom frame 707 to move together, thereby driving the entire hanging basket structure 7 to move together, so that the next empty partition slot on the partition bar 711 is directly below the circuit board body 11 clamped by the circuit board clamping structure 6, and then continue feeding. This process repeats, realizing intelligent mechanical feeding, avoiding manual feeding, improving the feeding efficiency of the circuit board body 11, and the setting of the slide rail 902 and the sliding sleeve 903 improves the sliding stability of the sliding frame 904.

[0046] When the present invention is in use, first, control the traveling structure 2 to move directly above the copper deposition tank 1, start the first motor 403 of the lifting structure 4, drive the first screw rod 401 to drive the lifting plate 402 to descend, and immerse the hanging basket structure 7 into the copper deposition tank 1. Set the immersion plating time according to the process requirements. After completion, the lifting structure 4 automatically raises the hanging basket structure 7 to the initial height. When the circuit board body 11 is completely immersed and plated in one immersion plating tank, the lifting structure 4 drives the hanging basket structure 7 to rise. At the same time, start the blower 505, and the air flow enters the air box 502 through the connecting pipe 506. During the lifting process of the air box 502, the driving wheel 509 rolls along the wavy driving plate 507, thereby driving the connecting rod 508 to move. The connecting rod 508 drives the air box 502 to slide. When the driving wheel 509 moves to the peak of the wavy driving plate 507, the air box 502 drives the fixed rod 510 to move, thereby compressing the first spring 513. When the lifting plate 402 continues to rise, the first spring 513 resets, thereby driving the air box 502 to reset, and the driving wheel 509 then rolls to the trough of the driving plate 507. This process repeats to realize the front-back swing of the air box 502 on the mounting frame 501, achieving uniform air drying. When it is necessary to adjust the blowing angle, the air guiding piece 504 can be manually toggled when the circuit board body 11 is being loaded, so that the blowing angle is better, improving the air drying effect and preventing the chemical solution inside one immersion plating tank from being carried into the inside of another immersion plating tank.

[0047] Then, when it is necessary to clamp the hanging basket rod 701 of the hanging basket structure 7, keep the first clamping plate 603 and the second clamping plate 608 in the vertical state, and clamp the hanging basket rod 701 through the arc-shaped parts of the first clamping plate 603 and the second clamping plate 608. When clamping, only need to start the hydraulic rod 605. The hydraulic rod 605 pushes the fixed strip 606, drives the second clamping plate 608 to close through the slide bar 607, and clamps the hanging basket rod 701. The positioning column 702 arranged on the hanging basket rod 701 and the positioning hole 703 on the second clamping plate 608 are used in cooperation, which improves the stability of the clamping structure 6 clamping the hanging basket structure 7. When it is necessary to transfer the circuit board body 11 on the conveying structure 10 to the hanging basket structure 7, the clamping action of the first clamping plate 603 and the second clamping plate 608 on the hanging basket rod 701 can be released first, and then the clamping structure 6 is lifted by the lifting structure, so that the hanging basket rod 701 will not affect the rotation of the first clamping plate 603 and the second clamping plate 608. Then start the second motor 602, and the second motor 602 drives the drive shaft 601 to rotate 90 degrees, so that the first clamping plate 603 and the second clamping plate 608 are in the horizontal state. Then start the hydraulic rod 605, and the hydraulic rod 605 contracts to drive the fixed strip 606 to move, and then drives the slide bar 607 to slide, driving the second clamping plate 608 to open. Then control the position of the control box 3 through the traveling structure 2, so that the first clamping plate 603 and the second clamping plate 608 are located on the upper and lower sides of the circuit board body 11 on the conveying structure 10. Then extend the hydraulic rod 605, and then drive the second clamping plate 608 to reset and clamp the circuit board body 11. The setting of the rubber pad 609 improves the clamping stability and avoids damage to the circuit board surface. Then start the lifting structure 4 to lift the clamping structure 6, and then drive the horizontal circuit board body 11 to rise. After rising to an appropriate height, start the second motor 602, and then drive the drive shaft 601 to rotate, driving the first clamping plate 603 and the second clamping plate 608 to rotate to the vertical state. At this time, the clamped circuit board body 11 is also in the vertical state and is directly above the hanging basket structure 7. Then start the lifting structure 4, so that the circuit board body 11 descends. After being stably guided by the guide shaft 708, it is inserted into the partition groove on the partition strip 711. When the lifting of a pair of circuit board bodies 11 is completed, the conveying structure 10 continues to convey the circuit board bodies 11, and at the same time, the clamping structure 6 releases the clamping action on the already loaded circuit board bodies 11. Then the lifting structure 4 drives the clamping structure to rise, and the clamping structure 6 continues to clamp the circuit board bodies 11 on the conveying structure 10 and send them to the hanging basket structure 7. When a partition groove on the partition strip 711 is already occupied, at this time, the hydraulic cylinder 906 in the feeding structure 9 contracts, driving the sliding frame 904 to move. The sliding frame 904 drives the hanging basket bottom frame 707 to move together, and then drives the entire hanging basket structure 7 to move together, so that the next empty partition groove on the partition strip 711 is directly below the circuit board body 11 clamped by the circuit board clamping structure 6. Then continue to feed, and so on, realizing intelligent mechanical feeding and avoiding manual feeding.The loading efficiency of the circuit board body 11 is improved, and the setting of the slide rail 902 and the sliding sleeve 903 improves the sliding stability of the sliding frame 904;

[0048] Finally, when it is necessary to adjust the distance between the hanging basket top frame 705 and the hanging basket bottom frame 707, symmetrically press the two pressing blocks 803 on the hanging basket top frame 705 by hand. The pressing blocks 803 drive the sliding plate 804 fixedly connected thereto to slide on the hanging basket top frame 705. At the same time, the sliding plate 804 slides along the fixed shaft 807 and compresses the second spring 808, so that the clamping block 805 on the sliding plate 804 disengages from the card slot 806 on the mounting strip 802. At this time, the telescopic strips 801 at the bottom ends on both sides of the hanging basket top frame 705 can slide relative to the mounting strips 802 at the top ends on both sides of the hanging basket bottom frame 707. After adjusting the height of the hanging basket according to actual needs, release the pressing block 803. Under the elastic force of the second spring 808, the sliding plate 804 drives the clamping block 805 to reset and re-engage into the corresponding card slot 806 to fix the adjusted height to adapt to the placement requirements of circuit boards of different sizes. Rotate the second screw 809 on the hanging basket bottom frame 707. Since the thread directions at both ends of the second screw 809 are opposite and it is threadedly connected to the two moving strips 710, when the second screw 809 rotates, the two moving strips 710 will slide along opposite directions on the multiple guide posts 709, and the partition strips 711 fixedly connected to the moving strips 710 move accordingly, thereby changing the distance between the partition strips 711 to adapt to the separated placement of circuit boards of different sizes, ensuring that the circuit boards remain relatively independent during the processing and avoiding mutual collision.
