Description

Technical Field

[0001] The present invention relates to the technical field of circuit board welding, and in particular to a circuit board welding device for a vehicle-mounted domain controller. Background Art

[0002] The vehicle domain controller is a key component in the modern automotive electronic architecture. It usually refers to a control unit that centrally manages specific functions or multiple functions in the vehicle. As the complexity of automotive electronic systems increases, the traditional distributed electronic control unit architecture has been unable to meet the growing functional requirements and data processing capabilities. Therefore, in order to improve the system's integration and maintainability, reduce the weight and cost of wiring harnesses, and enhance data processing capabilities, automobile manufacturers have begun to turn to the use of domain controller architecture. The circuit board is an important component of the vehicle domain controller. When the circuit board needs to be connected to other components inside the vehicle domain controller, the circuit board needs to be soldered.

[0004] Although the above patents and the prior art allow the circuit board to be turned over in a clamped state, thereby improving the welding efficiency, when welding the circuit board, tin wire is needed to weld the circuit board to other components. During the welding process, the stable delivery of the tin wire cannot be guaranteed, resulting in poor welding quality. In addition, multiple soldering points need to be soldered during the welding process, which will cause the tin wire on the circuit board to be connected to other soldering points, thus affecting the use effect of the circuit board. In addition, welding smoke will appear during the welding process, and the smoke will cause the detection component to fail to detect the welding status of the circuit board. Therefore, it is necessary to detect again to ensure the welding quality of the circuit board. A lot of manpower and material resources will be consumed in this process. Therefore, we propose a vehicle-mounted domain controller circuit board welding device. Summary of the invention

[0042] When it is necessary to protect the welding point, the second motor 31 is started through the control panel 12, and the second motor 31 drives the third driving sprocket 321 to rotate through the second output shaft 32, and the third driving sprocket 321 drives the third driven sprocket 412 to rotate through the third chain 322, so that the screw 411 drives the fixing box 41 and the welding gun 431 to descend, so that the welding gun 431 contacts the tin wire and performs welding, and the protective cover 62 seals the point to be welded, thereby ensuring that the tin liquid will not contact other welding points during the welding process, avoiding damage during the welding process;

[0043] For specific embodiment 3, please refer to Figures 1 to 7 According to a vehicle-mounted domain controller circuit board welding device provided in the second specific embodiment, this embodiment provides a further technical solution:

[0044] The smoke exhaust assembly 5 includes a plurality of first smoke outlet holes 51 opened on the top of the fixing box 41, a plurality of second smoke outlet holes 52 opened on the top of the protection box 43, and a plurality of fan blades 53 fixedly connected to the surface of the screw rod 411;

[0047] For specific example 4, please refer to Figures 1 to 12 According to a vehicle-mounted domain controller circuit board welding device provided in specific embodiment 3, this embodiment provides a further technical solution:

[0048] A spring 611 is fixedly connected inside the fixed cylinder 61, an extension cylinder 612 is slidably connected inside the fixed cylinder 61, the bottom of the spring 611 is fixedly connected to the top of the extension cylinder 612, a protective cover 62 is fixedly connected to the bottom of the extension cylinder 612, cooling oil is arranged inside the protective box 43, a pipeline 621 and a cooling cavity 623 are provided inside the protective cover 62, and a one-way valve 622 is arranged inside the pipeline 621;

[0049] It should be noted that there are eight one-way valves 622, and the opening and closing directions of each two of them are opposite. The opening 624 runs through the cooling cavity 623, and the tin liquid will not flow out from the position of the opening 624. The opening 624 and the extension tube are at the same horizontal height. When the tin wire contacts the welding gun 431 through the opening 624, by controlling the first motor 21 to reverse, it can be avoided that the tin wire is bent due to the movement of the protective cover 62, thereby affecting the subsequent welding effect.

[0050] When the screw 411 drives the fixed box 41 and the welding gun 431 to descend, the fixed box 41 drives the protective cover 62 to be stored inside the fixed box 41. At this time, the cooling oil inside the fixed box 41 flows into the cooling cavity 623 through the one-way valve 622 inside one of the pipes 621. At the same time, the original cooling oil in the cooling cavity 623 flows back to the fixed box 41 through the other one-way valve 622, so as to circulate, thereby preventing the tin liquid from adhering to the inner wall of the protective cover 62, so that the tin liquid can cover the solder joint.

[0051] Working principle: when it is necessary to convey the tin wire, the first motor 21 is started through the control panel 12, and the first motor 21 drives the first active sprocket 221 and the active gear 223 to rotate through the first output shaft 22, and the first active sprocket 221 drives the first driven sprocket 231 to rotate through the first chain 222, so that the first rotating rod 23 rotates, and the active gear 223 drives the driven gear 251 to rotate through the passive gear 261, so that the second rotating rod 25 drives the wire roller 252 to rotate, and then the tin wire enters the wire groove 241, and at the same time, the first output shaft 22 and the first rotating rod 23 drive the tin wire into the extension tube through the conveying roller 24, so that the tin wire is stably close to the welding gun 431, so as to avoid the tin wire from shaking during the conveying process. When it is necessary to protect the solder joint, the second motor 31 is started through the control panel 12, and the second motor 31 drives the third driving sprocket 321 to rotate through the second output shaft 32, and the third driving sprocket 321 drives the third driven sprocket 412 to rotate through the third chain 322, so that the screw 411 drives the fixing box 41 and the welding gun 431 to descend, so that the welding gun 431 contacts the tin wire and performs welding, and the height of the welding gun 431 descending is mainly controlled by the forward rotation time of the second motor 31, and the forward rotation time of the second motor 31 is preset in the control program entered into the control panel 12 before the whole vehicle-mounted domain controller circuit board welding device is debugged. When the whole vehicle-mounted domain controller circuit board welding device is started, the second motor 31 only needs to be adjusted according to the debugging. The program can be operated to make the protective cover 62 seal the points that need to be welded, so as to ensure that the tin liquid will not contact other welding points during the welding process, and avoid damage during the welding process. The second motor 31 drives the third active sprocket 321 to rotate through the second output shaft 32, and the third active sprocket 321 drives the third driven sprocket 412 to rotate through the third chain 322. When one welding is completed, the second motor 31 will reverse and reset according to the preset control program, and the second motor 31 will drive the screw 411 to rotate in the reverse direction during the reversal process. With the reverse rotation of the screw 411, the smoke inside the protective cover 62 after the welding is just completed can be transported to the fixed box 4 through the second smoke outlet 52 and the telescopic cylinder 42 by driving the fan blade 53 to rotate. 1, and when preparing for the next welding process, the second motor 31 can be controlled by the control program to cycle again, and then discharged to the outside of the box body 1 through the first smoke outlet 51, thereby avoiding the influence of smoke on the detection component 14 on the welding effect of the circuit board. When the screw 411 drives the fixing box 41 and the welding gun 431 to descend, the fixing box 41 drives the protective cover 62 to be stored in the fixing box 41. At this time, the cooling oil in the fixing box 41 flows into the cooling chamber 623 through the one-way valve 622 in one of the pipes 621. At the same time, the original cooling oil in the cooling chamber 623 flows back to the fixing box 41 through the other one-way valve 622, so as to circulate, thereby avoiding the tin liquid from adhering to the inner wall of the protective cover 62.Allow the tin liquid to cover the solder joints.
