[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and should not be construed as limitations on the present technical solution. The terms "first", "second", etc. are only used for the convenience of description and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined. "Several" means one or more, unless otherwise clearly and specifically defined.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, an automatic solder correction production line described in one embodiment of the utility model includes an automatic soldering machine 2, which is used to automatically add tin to the circuit board. An inclined online workbench 4 is arranged behind the automatic soldering machine 2, and the inclined online workbench 4 is used to manually add tin to the circuit board.

[0033] The automatic soldering machine 2 is responsible for tinning the fixed soldering points on the circuit board. The automatic soldering machine 2 can realize the automation and standardization of the soldering process through a precise control system and soldering system, improve the soldering accuracy and stability, and ensure the soldering quality.

[0034] However, after wave soldering, there are still some uncertain soldering defects, the automatic soldering machine 2 cannot automatically solder, and it may be difficult to achieve the ideal soldering effect under certain complex processes or special soldering requirements. Therefore, an inclined online workbench 4 is set after the automatic soldering machine 2. The design of the inclined online workbench 4 fully considers the ergonomic principles, so that the operator can comfortably perform manual maintenance, tinning, component installation and other operations on the circuit board. Through manual intervention, the shortcomings of the automatic soldering machine 2 in handling complex processes can be compensated, and the welding quality and consistency can be improved.

[0035] This embodiment combines the advantages of automation and manual operation, which can not only improve welding quality and production efficiency, but also cope with complex processes and special welding requirements. By optimizing and improving the structure and function of the assembly line, it can better meet the needs of modern industrial production.

[0036] like Figure 3 As shown, in a preferred embodiment, the automatic soldering machine 2 includes a frame, on which a conveying mechanism 201 and a first transfer mechanism 202 are provided, the conveying mechanism 201 is used to transport the circuit board, the first transfer mechanism 202 is provided with a solder head 203, the first transfer mechanism 202 is used to move the position of the solder head 203, and the solder head 203 is used to add tin to the solder joints on the circuit board.

[0037] When the equipment is started, the conveying mechanism 201 starts working, and the circuit board is smoothly conveyed to the soldering area. At this time, the first transfer mechanism 202 drives the solder head 203 to move along a preset path. During the movement, the solder head 203 accurately locates each solder joint on the circuit board, and then applies an appropriate amount of solder. The first transfer mechanism 202 is a three-axis transfer mechanism that can move forward and backward, left and right, and up and down, so that it can accurately locate each solder joint on the circuit board to ensure the quality of welding. In actual applications, a transfer mechanism with a higher degree of freedom can also be used to meet higher welding requirements.

[0038] In this embodiment, due to the precise movement of the solder head 203, the welding quality is guaranteed, the welding defect rate is reduced, and the qualified rate of the product is improved. Secondly, the high-speed operation and precise positioning of the automatic soldering machine 2 greatly improve the production efficiency, shorten the production cycle, and reduce the production cost.

[0039] like Figure 5As shown, in a preferred embodiment, the tilted online workbench 4 includes a frame, on which a movable frame 401 capable of adjusting the tilt angle is movably arranged, on which a guide rail 406 is arranged, and below the guide rail 406, an operating table 403 is arranged. The difference between the guide rail 406 and the conveying mechanism 201 is that the guide rail 406 is not provided with a conveyor belt, and the circuit board is manually pushed to move on the guide rail 406 by a person, and the operation time on the tilted online workbench 4 is uncertain, which is convenient for the operator to operate. In actual application, the conveying mechanism 201 can also be used to replace the guide rail 406.

[0040] One side of the movable frame 401 is hinged with the frame, and a telescopic rod 402 is arranged between the other side of the movable frame 401 and the frame. The telescopic rod 402 is extended to push the movable frame 401 to rotate and tilt it, and the telescopic rod 402 is retracted to pull the movable frame 401 to rotate and level it. The telescopic rod 402 is a pneumatic push rod or an electric push rod.

[0041] When the angle of the workbench needs to be adjusted to meet different operating requirements, the operator only needs to control the telescopic rod 402. The telescopic rod 402 begins to extend, and its driving force acts on one side of the movable frame 401, so that the movable frame 401 rotates around the hinge point as the axis and gradually tilts to the required angle. Conversely, when the telescopic rod 402 is retracted, its pulling force pulls the movable frame 401 back to a horizontal state.

[0042] In this embodiment, by adjusting the tilt angle of the movable frame 401, the operator can perform manual tinning operations more comfortably, effectively reducing fatigue from long-term operations and improving work efficiency. Secondly, the tilted workbench helps the operator to better observe the welding conditions on the circuit board, promptly discover and deal with problems in the welding process, thereby improving welding quality. In addition, the precise control of the telescopic rod 402 makes the angle adjustment of the workbench more accurate and stable, providing reliable support for welding operations.

[0043] like Figure 5 As shown, in a preferred embodiment, a lighting lamp 404 is rotatably provided on the frame above the movable frame 401, and a shading plate 405 is provided on one side of the lighting lamp 404. The shading plate 405 is used to adjust the lighting area to avoid direct exposure to human eyes.

[0044] In the movable frame 401 area above the rack, the lighting lamp 404 is flexibly arranged through a rotating mechanism. When the operator needs to adjust the lighting angle, the lighting lamp 404 can be rotated to a suitable position through the rotating mechanism to provide sufficient lighting for the working area. At the same time, the shading plate 405 can also be adjusted as needed. When the light of the lighting lamp 404 is too strong or directly shines into the human eye, the operator can move the shading plate 405 to effectively block part of the light, adjust the lighting area, and avoid visual interference.

[0045] In this embodiment, the lighting lamp 404 provides stable and uniform lighting, so that the operator can clearly see the details on the circuit board when performing manual tinning operations on the inclined online workbench 4, thereby improving the accuracy and efficiency of the operation. Secondly, the introduction of the shading plate 405 effectively avoids direct light and excessive lighting from the lighting lamp 404, protects the operator's vision health, and also improves the comfort of the working environment. In addition, the flexible adjustment function of the lighting lamp 404 and the shading plate 405 allows the operator to freely adjust the lighting area and light intensity according to actual needs, providing the operator with a more convenient and humane welding working environment.

[0046] like Figure 4 As shown, in a preferred embodiment, a first inclined docking platform 3 is arranged between the automatic soldering machine 2 and the inclined online workbench 4, and a second inclined docking platform 5 is arranged behind the inclined online workbench 4. The first inclined docking platform 3 and the second inclined docking platform 5 both include a frame, and a movable frame 401 capable of adjusting the tilt angle is movably arranged on the frame, and a conveying mechanism 201 is arranged on the movable frame 401.

[0047] After the automatic soldering machine 2 completes the preliminary soldering operation, the circuit board will smoothly transition to the inclined online workbench 4 through the first inclined docking station 3. The movable frame 401 of the first inclined docking station 3 ensures that the circuit board is smoothly and accurately transferred from the automatic soldering machine 2 to the workbench by accurately adjusting the tilt angle. Similarly, when the operator completes the manual soldering on the inclined online workbench 4, the circuit board passes through the second inclined docking station 5 and again adjusts the tilt angle of the movable frame 401 to achieve a smooth transition to the next process. During the whole process, the conveying mechanism 201 always operates stably to ensure that the circuit board is smoothly and unimpededly transferred between the docking stations.

[0048] In this embodiment, by setting the first inclined docking platform 3 and the second inclined docking platform 5, not only the seamless docking between the automatic soldering machine 2 and the inclined online workbench 4 is achieved, but also the overall efficiency of the production line is greatly improved. In addition, the introduction of the first inclined docking platform 3 and the second inclined docking platform 5 also makes the layout of the entire production line more compact and reasonable.

[0049] like Figure 4 As shown, in a preferred embodiment, a push plate mechanism 301 is arranged on the frame on the first inclined docking platform 3, and the push plate mechanism 301 includes a first linear motion component 302 arranged along the direction of the conveying mechanism 201, and a driving motor 303 is arranged at the movable end of the first linear motion component 302, and a push block 304 is arranged on the output shaft of the driving motor 303.

[0050] When the circuit board is transferred to the position of the push plate mechanism 301 through the conveying mechanism 201, the first linear motion component 302 drives the driving motor 303 and the push block 304 to move. The first linear motion component 302 provides a stable linear motion trajectory for the push block 304, ensuring that the push block 304 can accurately push the circuit board from the conveying mechanism 201 to the inclined online workbench 4. With the movement of the push block 304, the circuit board is smoothly and accurately pushed to the designated position of the workbench, ready for subsequent welding operations. Or the driving motor 303 drives the push block 304 to rotate. When the push block 304 is vertically downward, the circuit board can be pushed to move. When the push block 304 is horizontally or vertically upward, the circuit board can move normally on the conveying mechanism 201.

[0051] In this embodiment, through the coordinated work of the driving motor 303 and the first linear motion assembly 302, the push block 304 can accurately control the pushing position and speed of the circuit board and control the production process.

[0052] like Figure 7 and Figure 8 As shown, in a preferred embodiment, a tin slag removal device 6 is arranged behind the inclined online workbench 4, and the tin slag removal device 6 includes a frame, a conveying mechanism 201 is arranged on the frame, and a second transfer mechanism 601 is arranged on the frame above the conveying mechanism 201, and a cleaning brush 602 and a dust suction pipe 603 are arranged at the movable end of the second transfer mechanism 601.

[0053] After the circuit board completes the manual tinning operation on the tilted online workbench 4, it is transported to the tin slag removal device 6 for subsequent cleaning. The second transfer mechanism 601 of the tin slag removal device 6 moves along a preset path. The cleaning brush 602 equipped at its movable end will be close to the surface of the circuit board and gently brush off excess solder and tin slag. At the same time, the dust suction tube 603 follows the movement of the cleaning brush 602 to quickly suck away the brushed tin slag and dust to ensure a clean working environment. The second transfer mechanism 601 is also a three-axis transfer mechanism that can move forward and backward, left and right, and up and down, so that the circuit board can be fully cleaned to ensure welding quality. In actual applications, a transfer mechanism with a higher degree of freedom can also be used to meet higher cleaning requirements.

[0054] In this embodiment, the cleaning brush 602 and the dust suction tube 603 are used together to efficiently remove the solder residue and dust on the surface of the circuit board, ensuring the stability and consistency of the welding quality. At the same time, the automated cleaning process reduces manual intervention, reduces the labor intensity of the operator, and improves production efficiency. In addition, the improvement of the cleaning work also helps to extend the service life of the equipment and reduce the failure and damage caused by the accumulation of tin residue.

[0055] like Figure 1As shown, in a preferred embodiment, the tin slag removal device 6 is followed by an A-side AOI optical inspection machine 7, a plate turning machine 8 and a B-side AOI optical inspection machine 9.

[0056] After the circuit board is cleaned by the desoldering device 6, it first enters the A-side AOI optical inspection machine 7. The AOI optical inspection machine uses a combination of light sources, cameras and software to perform precise optical inspection on the A side of the circuit board to identify any potential welding defects or defective products. Once the inspection is completed, the circuit board will be transported to the flip machine 8. The flip machine 8 flips the circuit board over to prepare for the inspection of the B side. Finally, the circuit board enters the B-side AOI optical inspection machine 9 and undergoes the same optical inspection process. Throughout the process, various devices work together to ensure that both sides of the circuit board can be inspected.

[0057] In this embodiment, by introducing the A-side AOI optical inspection machine 7, the panel turning machine 8 and the B-side AOI optical inspection machine 9, the production line realizes the automated optical inspection of both sides of the circuit board, improves the inspection efficiency and accuracy, reduces the errors caused by human factors, and ensures the consistency and stability of product quality. In addition, the automated inspection also reduces the labor intensity of the operator and improves the overall production efficiency. Through comprehensive optical inspection, the production line can timely detect and deal with potential welding defects, thereby reducing the defective rate and improving product competitiveness.

[0058] like Fig. 9 As shown, in a preferred embodiment, a stamping device 10 is arranged behind the B-side AOI optical inspection machine 9, and the stamping device 10 includes a frame, a conveying mechanism 201 is arranged on the frame, a first horizontal moving frame 1001 is arranged on the conveying mechanism 201, a telescopic rod 402 is arranged at the movable end of the first horizontal moving frame 1001, and a stamp 1002 is arranged at the bottom of the telescopic rod 402. The telescopic rod 402 can also be a pneumatic push rod or an electric push rod.

[0059] After the qualified circuit board is detected by the B-side AOI optical inspection machine 9, it will automatically enter the printing device 10 for the next step. The telescopic rod 402 of the first horizontal movable frame 1001 of the printing device 10 works, pushing the seal 1002 at the bottom to press down, contacting with the surface of the circuit board, and completing the printing action. Afterwards, the telescopic rod 402 shrinks, the seal 1002 is lifted, and the first horizontal movable frame 1001 returns to the initial position at the same time, waiting for the next printing task. In this embodiment, the seal 1002 is a qualified seal, and the printing is performed only when the detection is qualified. The printing position can be adjusted by the first horizontal movable frame 1001, which is suitable for different circuit board production. The first horizontal movable frame 1001 includes a transverse slide and a longitudinal slide. The transverse slide can slide on the longitudinal slide perpendicular to the movement direction of the conveying mechanism 201, and the telescopic rod 402 can slide on the transverse slide parallel to the movement direction of the conveying mechanism 201.

[0060] In this embodiment, the stamping device 10 can accurately control the position and strength of the seal 1002, ensure the clarity and consistency of the stamping, and improve product quality. In addition, through the stamping operation, a mark or information can be left on the circuit board, which is convenient for subsequent tracking and management.

[0061] like Fig.10 As shown, in a preferred embodiment, a visual inspection device 11 is arranged behind the printing device 10, and the visual inspection device 11 includes a frame, a conveying mechanism 201 is arranged on the frame, a second horizontal movable frame 1101 is arranged on the conveying mechanism 201, a camera 1102 is arranged at the movable end of the second horizontal movable frame 1101, and a display screen 1103 electrically connected to the camera 1102 is arranged on the frame.

[0062] After the printing operation is completed, the circuit board will be automatically transmitted to the visual inspection device 11 for final inspection. At this time, the position of the camera 1102 is moved by the second horizontal movable frame 1101. The camera 1102 captures the image of the circuit board and transmits it to the display screen 1103. The operator can observe the real-time image on the display screen 1103 to conduct a detailed inspection of the circuit board to confirm whether it meets the quality standards. If any problems are found, the operator can take appropriate measures to deal with them in time. The second horizontal movable frame 1101 also includes a transverse slide and a longitudinal slide. The transverse slide can slide on the longitudinal slide in a direction perpendicular to the movement direction of the conveying mechanism 201, and the camera 1102 can slide on the transverse slide in a direction parallel to the movement direction of the conveying mechanism 201.

[0063] In this embodiment, the operator can visually observe the actual situation of the circuit board through the cooperation of the camera 1102 and the display screen 1103, thereby more easily discovering potential problems. At the same time, the second horizontal movable frame 1101 enables the camera 1102 to cover a wider inspection area, thereby improving the inspection efficiency.

[0064] like Figure 6 As shown, in a preferred embodiment, the conveying mechanism 201 includes a fixed frame and a sliding frame, the fixed frame connected to the frame and the sliding frame movably connected to the frame, two conveyor belts are respectively arranged on the fixed frame and the sliding frame, a width adjustment component is arranged between the fixed frame and the sliding frame, and the width adjustment component is used to adjust the distance between the two conveyor belts.

[0065] The width adjustment assembly includes a screw rod and a slide rod. The screw rod is threadedly connected to the slide frame, the screw rod is rotationally connected to the fixed frame, the slide rod is slidably connected to the slide frame, and rotating the screw rod is used to increase or decrease the distance between the fixed frame and the slide frame.

[0066] When the distance between the two conveyor belts in the conveying mechanism 201 needs to be adjusted, the operator rotates the screw in the width adjustment assembly. Since the screw is threadedly connected to the sliding frame and rotatably connected to the fixed frame, the rotation of the screw will push the sliding frame to slide on the sliding rod. As the screw rotates in different directions, the sliding frame will move closer to or away from the fixed frame, thereby changing the distance between the two, thereby driving the distance between the conveyor belts set on them to increase or decrease.

[0067] In this embodiment, through a simple rotation action, the operator can quickly and accurately adjust the spacing between the conveyor belts to meet the conveying requirements of circuit boards of different sizes and specifications, thereby improving the adaptability and flexibility of the production line and reducing the cost and time of replacing conveying mechanisms 201 of different specifications.

[0068] like Figure 1 , Figure 2 , Fig.11 As shown, in a preferred embodiment, the automatic solder correction line includes a tin holding device 12, which includes a power line trough, an air pipe and a solder exhaust pipe. A production line is set on both sides of the tin holding device 12, and the production line includes a horizontal docking station 1, an automatic soldering machine 2, a first inclined docking station 3, three inclined online workbenches 4, a second inclined docking station 5, a tin slag removal device 6, an A-side AOI optical inspection machine 7, a flip machine 8, a horizontal docking station 1, a B-side AOI optical inspection machine 9, a stamping device 10, a visual inspection device 11 and a horizontal docking station 1. The horizontal docking station 1 includes a frame, and a conveying mechanism 201 is set on the frame.

[0069] In this embodiment, the circuit board starts from the initial horizontal docking station 1 and passes through the automatic soldering machine 2 in sequence to add tin to the fixed solder joints. Subsequently, the circuit board smoothly transitions to the inclined online workbench 4 through the first inclined docking station 3, and the operator performs manual tinning correction operations on the workbench. After passing the second inclined docking station 5, the circuit board enters the tin slag removal device 6 to remove excess solder residue. Next, the circuit board passes through the AOI optical inspection machine on the A side and the B side to comprehensively detect the welding quality. The circuit board is flipped over by the flipping machine 8 to ensure that both sides are inspected. For the qualified circuit board, the stamping device 10 stamps and marks the circuit board. Finally, the circuit board is manually inspected by the visual inspection device 11 to ensure that the quality is correct, and then it is smoothly transferred to the next process through the horizontal docking station 1.

[0070] The overall design of the automatic solder correction line realizes the automation and efficiency of welding operations, and improves production efficiency and quality stability. By integrating a variety of advanced equipment and technologies, such as automatic soldering machines 2, tilting online workbenches 4, AOI optical inspection machines, etc., the line can continuously and stably perform welding, correction and inspection operations to ensure production quality. At the same time, the layout of the line is reasonable, and the connection between the various equipment is smooth, which reduces the pauses and waiting time in the production process and improves the overall production efficiency. In addition, the line also has high flexibility and scalability, and can adapt to the production needs of circuit boards of different specifications and requirements, providing users with reliable production guarantees.
