Description

Technical Field

[0001] This invention relates to the field of tin spraying structure technology, specifically to a tin spraying structure for controlling a circuit board surface treatment device. Background Technology

[0002] Controlling the surface treatment process of circuit boards, especially the tin plating process for solderability protection of exposed copper surfaces such as pads and vias, is a key step in ensuring the reliability of circuit board soldering and the stability of long-term electrical performance. Among them, hot air leveling is one of the most widely used tin plating processes. Its principle is to immerse the circuit board in molten solder to form a uniform tin plating layer on its surface, and then use a high-temperature and high-pressure hot air knife to blow away excess solder, thereby obtaining a flat, bright tin layer with controllable thickness. In the existing technology, traditional tin plating equipment mostly adopts a single-station operation mode, that is, in one work cycle, the processes of board loading, tin immersion, hot air leveling, and unloading are all completed in the same station. This mode has obvious efficiency bottlenecks. When the circuit board is being tin-immersed or hot air leveled, the equipment is in a continuous processing state and cannot perform loading or unloading operations at the same time. This results in a lot of time being wasted waiting for the process to change, low equipment utilization, and limited production capacity. Summary of the Invention

[0003] The purpose of this invention is to provide a solder spraying structure for a control circuit board surface treatment device, in order to solve the problem mentioned in the background art that traditional solder spraying equipment mostly adopts a single-station operation mode, that is, in one work cycle, the processes of board loading, soldering, hot air leveling, and unloading are all completed sequentially at the same station. This mode has obvious efficiency bottlenecks. When the circuit board is being soldered or hot air leveled, the equipment is in a continuous processing state and cannot perform loading or unloading operations at the same time, resulting in a lot of time being spent waiting for the process to change, low equipment utilization, and limited production capacity.

[0005] As a preferred embodiment of the present invention: the adjustment structure includes a first inner fixed box, a bidirectional lead screw, a movable slider, and a second servo motor. The first inner fixed box is fixedly installed inside the support body by bolts. The bidirectional lead screw is rotatably installed inside the first inner fixed box. Two movable sliders are symmetrically installed on the outer side of the bidirectional lead screw. The movable sliders are slidably connected to the first inner fixed box. One side of the movable slider is fixedly connected to one side of the hot air knife. The second servo motor is installed on one side of the first inner fixed box. The output end of the second servo motor is fixedly connected to the bidirectional lead screw.

[0006] As a preferred embodiment of the present invention: a second inner fixing box is fixedly connected inside the supporting body, and two inner sliders are symmetrically slidably arranged inside the second inner fixing box. The other side of the hot air knife is fixedly connected to the inner sliders, and a first limiting rod is slidably arranged inside the inner sliders.

[0007] As a preferred embodiment of the present invention: accordion cloth is provided between the two sides of the movable slider and the first inner fixed box, and between the two sides of the inner slider and the second inner fixed box.

[0008] As a preferred embodiment of the present invention: the rotating structure includes a rotating column, a worm gear, a worm, and a servo motor. The rotating column is fixedly connected to the bottom of the rotating top plate. The rotating column is rotatably connected to the supporting body. The worm gear is fixedly connected to the outer side of the rotating column. A worm is rotatably installed inside the supporting body. The worm is meshed with the worm gear. A servo motor is fixedly installed inside the supporting body by bolts. The output end of the servo motor is fixedly connected to the worm.

[0009] As a preferred embodiment of the present invention: a support frame is provided on one side of the support column, a chain conveyor is provided on the inner side of the support frame, a plurality of circuit board support platforms are provided on the chain conveyor, and two top limiting brackets are symmetrically fixed to the top of the circuit board support platforms.

[0010] As a preferred embodiment of the present invention: a No. 3 servo motor is fixedly installed inside the support column by bolts, and the output end of the No. 3 servo motor is fixedly connected to the top rotating table.

[0011] As a preferred embodiment of the present invention: four No. 2 limiting rods are symmetrically fixed to the top of the bottom support plate, and the No. 2 limiting rods are slidably connected to the top rotating platform.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: The dual-station alternating operation significantly improves production efficiency. By setting a rotating top plate that can rotate 180 degrees and two symmetrically arranged through-plate frames, combined with a manual feeding and automated loading / unloading system, a dual-station alternating continuous operation mode is achieved. When the circuit board in one through-plate frame is undergoing tinning and hot air leveling, the other through-plate frame can simultaneously undergo manual feeding, eliminating downtime caused by waiting for feeding in traditional single-station equipment, maximizing equipment utilization, and nearly doubling production efficiency compared to the single-station structure. The self-locking characteristic of the worm gear mechanism ensures stable locking of the rotating top plate under load. This design avoids the risk of positional deviation during processing. It employs a two-way lead screw driven by a second servo motor to link two hot air knives, along with a double-sided guide support structure for the second inner fixed box and inner slider. This enables synchronous, precise, and automated adjustment of the hot air knife spacing. This structure can quickly adapt to circuit boards of different widths, ensuring that the hot air knives always blow evenly onto both sides of the circuit board at the optimal distance and angle. This guarantees that products of different specifications can achieve a smooth, bright, high-quality tin layer surface. The dynamic sealing design of the accordion cloth effectively isolates tin vapor and high-temperature gas from corroding the internal transmission components, significantly extending the service life and maintenance cycle of the precision adjustment mechanism.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 4This invention provides a technical solution: a solder spraying structure for a control circuit board surface treatment device, comprising a support body 1, a solder pot 2 disposed inside the support body 1, a rotating top plate 3 rotatably disposed on the top of the support body 1, two through-plate frames 4 symmetrically fixed inside the rotating top plate 3, two limiting top seats 6 symmetrically slidably disposed inside the through-plate frames 4, an opening 34 on the top of the support body 1 that mates with the through-plate frames 4, two hot air knives 15 symmetrically disposed on the inner side of the support body 1, an adjustment structure disposed inside the support body 1, the hot air knives 15 being connected to the adjustment structure, and the support body... The internal structure of the machine body 1 is equipped with a rotating structure. The rotating top plate 3 is connected to the rotating structure. A support column 20 is provided on one side of the machine body 1. A top rotating platform 22 is rotatably provided on the top of the support column 20. Two second cylinders 23 are symmetrically fixed on the top of the top rotating platform 22 by bolts. The output end of the second cylinder 23 is fixed to a bottom support plate 32. A bottom fixing frame 24 is fixed on the bottom of the bottom support plate 32 by bolts. Two pneumatic grippers 25 are symmetrically installed inside the bottom fixing frame 24. Two clamping plates 26 are symmetrically installed on the bottom of the pneumatic grippers 25 for clamping the circuit board.

[0022] By setting up a rotatable top plate 3 and a matching through-plate frame 4, combined with a pneumatic gripper 25 structure that can move horizontally to grip the circuit board, the entire process of circuit board dipping and removal is automated. The pneumatic gripper 25 and the second cylinder 23 work together to accurately and stably grip and transfer the circuit board. The setting of the rotating top plate 3 allows the solder pot 2 to alternately serve two stations. When one station is dipping in solder, the other station can be loading materials, which greatly improves production efficiency and the continuous operation capability of the equipment.

[0023] The specific architecture and operation logic of the tin furnace 2, cylinder, servo motor 10, second cylinder 23, and chain conveyor 28 in this application, which are coordinated and controlled by an external controller, are consistent with the existing technology in this field. The servo motor 10 used is equipped with an encoder, which can provide real-time feedback on the speed, position, and other information of the servo motor 10. This control method has been maturely applied in many similar industrial scenarios, so it will not be discussed in detail here.

[0024] The adjustment structure includes an inner fixed box 11, a bidirectional lead screw 12, a movable slider 14, and a servo motor 13. The inner fixed box 11 is fixedly installed inside the support body 1 by bolts. The bidirectional lead screw 12 is rotatably installed inside the inner fixed box 11. Two movable sliders 14 are symmetrically installed on the outside of the bidirectional lead screw 12. The movable sliders 14 are slidably connected to the inner fixed box 11. One side of the movable sliders 14 is fixedly connected to one side of the hot air knife 15. The servo motor 13 is installed on one side of the inner fixed box 11. The output end of the servo motor 13 is fixedly connected to the bidirectional lead screw 12.

[0025] By setting up a bidirectional lead screw 12 driven by servo motor 13 to link the two hot air knives 15, the synchronous, precise and automated adjustment of the distance between the two hot air knives 15 is realized. This structure can quickly adapt to circuit boards of different widths and ensure that the hot air knives always blow on both sides of the circuit board at the optimal distance and angle, thereby ensuring that products of different specifications can obtain a high-quality tin layer surface, improving the versatility of the equipment and the consistency of the process.

[0026] Among them, the second inner fixed box 17 is fixedly connected to the inside of the support body 1. Two inner sliders 18 are symmetrically slidably arranged inside the second inner fixed box 17. The other side of the hot air knife 15 is fixedly connected to the inner sliders 18. The inner sliders 18 are slidably arranged with a first limiting rod 19 inside.

[0027] By adding a second inner fixed box 17 and an inner slider 18 slidably connected to it, a stable sliding support is provided on the other side for the hot air knife 15. Combined with the structure of the first inner fixed box 11, the hot air knife 15 can obtain stable and reliable guidance and support at both ends when it moves under the drive of the bidirectional screw 12. This effectively prevents the hot air knife 15 from deforming, vibrating or jamming that may occur in the long-term high-temperature working environment, ensuring its smooth operation and positional accuracy, and extending its service life.

[0028] Among them, accordion cloth 16 is provided between the two sides of the movable slider 14 and the first inner fixed box 11, and between the two sides of the inner slider 18 and the second inner fixed box 17.

[0029] By setting accordion cloth 16 on both sides of the moving slider 14 and the inner slider 18, a dynamic sealing barrier is formed. This design can effectively isolate the tin vapor, flux fumes and high-temperature hot air volatilized from the tin furnace 2, preventing these contaminants from entering and accumulating inside the first inner fixed box 11 and the second inner fixed box 17, thereby protecting the internal lead screw, guide rail and servo motor precision transmission components from corrosion and contamination, and significantly improving the reliability and maintenance cycle of the core adjustment mechanism.

[0030] The rotating structure includes a rotating column 7, a worm gear 8, a worm 9, and a servo motor 10. The rotating column 7 is fixedly connected to the bottom of the rotating top plate 3 and is rotatably connected to the support body 1. The worm gear 8 is fixedly connected to the outside of the rotating column 7. The worm 9 is rotatably installed inside the support body 1 and is meshed with the worm gear 8. The servo motor 10 is fixedly installed inside the support body 1 by bolts, and the output end of the servo motor 10 is fixedly connected to the worm 9.

[0031] A servo motor 10 drives the worm gear 9 and worm wheel 8 to rotate the rotating top plate 3. The worm gear mechanism has a self-locking characteristic, which can be precisely locked at any position, ensuring that the rotating top plate 3 maintains an extremely stable posture when carrying the circuit board for tinning and air knife blowing operations, without unexpected rotation or deviation, thereby ensuring processing accuracy and safety.

[0032] Among them, a support frame 33 is provided on one side of the support column 20, and a chain plate conveyor 28 is provided on the inner side of the support frame 33. Multiple circuit board support platforms 29 are provided on the chain plate conveyor 28, and two top limiting brackets 30 are symmetrically fixed to the top of the circuit board support platform 29.

[0033] By adding a feeding structure including a chain conveyor 28 and a circuit board support platform 29, and linking it with the pick-and-place device, automatic continuous feeding of circuit boards is realized, and the top limiting bracket 30 can prevent the circuit boards from shifting during the conveying process.

[0034] Among them, the support column 20 is fixedly installed with a No. 3 servo motor 21 by bolts, and the output end of the No. 3 servo motor 21 is fixedly connected to the top rotating table 22.

[0035] Driven by the No. 3 servo motor 21, the top rotating table 22 and the clamping mechanism on it are rotated as a whole, so that the pneumatic gripper 25 can flexibly switch between the unloading station, the tin dipping station, and possible buffer or turning stations.

[0036] Among them, four No. 2 limit rods 27 are symmetrically fixed to the top of the bottom support plate 32, and the No. 2 limit rods 27 are slidably connected to the top rotating platform 22.

[0037] By setting four second-level limit rods 27 that are slidably connected to the top rotating platform 22, multi-directional and high-rigidity vertical guidance is provided for the bottom support plate 32 and the pneumatic gripper 25 carried on it to move up and down under the drive of the second cylinder 23. This effectively prevents the gripper from swinging or deflecting during the lifting process, ensuring that the circuit board is accurately positioned and has a stable posture when picked up, transferred and immersed in the solder pot, avoiding bumps or poor soldering caused by shaking.

[0038] Among them, multiple inner guide placement racks 31 are symmetrically and equidistantly arranged on the inner side of the support body 1, and a box door 35 is provided on one side of the support body 1.

[0039] Multiple internal guide racks 31 are provided inside the support body 1, providing a convenient and orderly dedicated storage location for hot air knives and sensor components that need to be maintained or replaced, making them easy to access quickly.

[0040] Among them, four No. 1 cylinders 5 are symmetrically arranged inside the rotating top plate 3, and the output end of the No. 1 cylinder 5 is fixedly connected to the limiting top seat 6.

[0041] By setting a limiting top seat 6 driven by cylinder 5 on the rotating top plate 3, the automatic clamping and positioning of the circuit board placed in the through plate frame 4 is realized. This structure can quickly and reliably fix circuit boards of different thicknesses, preventing the circuit boards from sliding or falling off during the rotation of the rotating top plate 3 or during tinning and hot air leveling, thus ensuring the stability and safety of the processing.

[0042] Specifically, during use, the operator manually places the circuit board to be processed into the through-plate frame 4 of the rotating top plate 3 from one side of the supporting body 1. The first cylinder 5 is activated, pushing the four limiting top seats 6 to slide synchronously along the inner side of the through-plate frame 4, clamping the edges of the circuit board from four directions and positioning it accordingly. The servo motor 10 is activated, driving the worm gear 8 through the worm 9, causing the rotating column 7 to rotate 180 degrees. The rotating top plate 3 rotates accordingly, transferring the through-plate frame 4 holding the circuit board directly above the solder pot 2. The self-locking characteristic of the worm gear mechanism ensures that the rotating top plate 3 is stably locked under load. The second cylinder 23 is activated, driving the pneumatic gripper 25 to descend, thus transferring the circuit board to the upper part of the solder pot 2. The circuit board is vertically immersed in the molten solder in the solder bath 2. The immersion depth and time are precisely controlled according to process requirements. The molten solder fully contacts the exposed copper pads and hole walls of the circuit board to form a uniform solder plating layer. After immersion, the second cylinder 23 retracts to smoothly lift the circuit board from the solder bath 2. At the same time, it is subjected to hot air treatment by the hot air knife 15. The second servo motor 13 is started, driving the bidirectional lead screw 12 to rotate, which drives the two moving sliders 14 to move synchronously along the first inner fixed box 11. At the same time, the inner slider 18 slides along the second inner fixed box 17 and the first limit rod 19. The distance between the two hot air knives 15 is adjusted to match the width of the circuit board. The moving sliders 14 and the inner slider 18 on both sides... The accordion cloth 16 slides and extends, dynamically sealing and isolating tin vapor and high-temperature gas. The hot air knife 15 is activated, spraying high-temperature and high-pressure airflow to evenly blow on both sides of the circuit board, removing excess molten tin from the surface and making the tin layer smooth and shiny. After the circuit board is processed, it is raised above the through frame 4, and the top plate 3 rotates 180 degrees to return to the initial position. The third servo motor 21 is activated, driving the top rotating table 22 to rotate, so that the pneumatic gripper 25 is facing the processed circuit board. The second cylinder 23 descends, and the clamping plate 26 clamps the edge of the circuit board and lifts and adjusts the height to complete the process of immersing the circuit board into the tin furnace 2. The top rotating table 22 rotates again to transfer the circuit board to the chain conveyor. Above machine 28, cylinder 23 descends to place the circuit board onto the circuit board support platform 29 of the chain conveyor 28. The pneumatic gripper 25 releases, and the chain conveyor 28 starts to transport the processed circuit board to the next process or unloading area. At the same time, the operator can continue to manually place new circuit boards to be processed into another through frame 4 of the rotating top plate 3 on the other side of the support body 1, realizing continuous production with alternating dual workstations. The inner guide placement frame 31 provides a dedicated storage location for components such as the hot air knife 15. This structure achieves efficient, stable, and high-quality operation of circuit board tin plating through manual feeding, automated tin plating and hot air leveling, and automated unloading to the conveyor.
