[0001] The invention relates to the technical field of welding devices, in particular to a mainboard component welder for computer hardware processing. Background Art

[0002] In today's digital age, the demand for computer hardware continues to grow. As one of the core components of a computer, the quality and performance of the motherboard are crucial. The traditional method of welding motherboard components usually uses manual welding, which is relatively slow, especially when a large number of components need to be welded. It often takes a long time to weld a component, which seriously affects the production schedule;

[0003] During the welding process, workers need to perform a series of operations, such as preparing solder, adjusting welding angles, and waiting for the solder joints to cool down. These steps are time-consuming. After working for a long time, workers may become fatigued, further reducing welding accuracy.

[0004] Manual welding is harmful to workers' health. Harmful gases and smoke are produced during welding, such as tin smoke and rosin volatiles. Long-term inhalation of these substances will cause harm to workers' respiratory system and physical health. Strong light and high temperature during welding may also cause damage to workers' eyes and skin;

[0005] Therefore, developing a novel motherboard component welding device for computer hardware processing has important practical significance. Summary of the invention

This is very important to ensure the accuracy of welding, because any slight displacement may cause inaccurate solder joints and affect the welding quality;

[0024] When the second motor is running, it drives the fan to rotate and generate cooling air. The cooling air is blown into the air cooling pipe through the guiding effect of the air guide plate, and blown to the placement platform through the air outlet.

Through the transmission of the belt, the height of the welding position can be adjusted with high precision to ensure the accuracy of the welding point. The setting of the transmission component makes it possible for the solder wire and the electric soldering iron to contact the motherboard at the same position when the lifting device reaches the welding height to achieve welding. The stable lifting component can ensure that the electric soldering iron always maintains the appropriate pressure and angle during the welding process, thereby improving the quality and reliability of welding.

[0026] 4. The motherboard component welder for computer hardware processing can form a relatively stable welding space through the setting of the fixing device, and the fixing cover can reduce the influence of the external airflow on the welding process, thereby improving the stability and quality of welding. During the welding process, the fixing cover can press the motherboard components to achieve the fixing effect, and the fixing cover can block the cooling air blown out of the air outlet during welding. When the welding is completed, the lifting device is lifted, and the fixing device rises accordingly, and the cooling air blows to the welding point to achieve cooling of the motherboard.

[0040] The frame 1 provides a stable installation position for each component of the device, ensuring that the device remains stable during operation. The first motor 14 and the screw rod 15 can quickly and continuously transport the mainboard components to be welded to the welding position without manual movement and positioning, which greatly saves time, improves the speed of the overall welding operation, avoids position deviations and unstable factors that may be caused by manual operation, and reduces welding defects caused by inaccurate position. When the first motor 14 is running, the output end of the first motor 14 drives the screw rod 15 to rotate, and the screw rod 15 moves in coordination with the second fixed block 18. The first fixed block 17 is slidably connected to the outer surface of the slide bar 16, and the mainboard placement component 2 moves together with the first fixed block 17 and the second fixed block 18.

The second motor 21 is fixedly mounted on the outer side of the air cooling pipe 22. The air cooling pipe 22 is fixedly connected to the bottom of the first fixed block 17 and the second fixed block 18. The output end of the second motor 21 is fixedly connected to a fan 24, and the fan 24 is fixedly mounted on the surface of the air cooling pipe 22. An air outlet 23 is provided on the inner side of the air cooling pipe 22. An air guide plate 25 is fixedly mounted inside the air cooling pipe 22. When the second motor 21 is running, the fan 24 is driven to rotate to generate cooling air. The cooling air is blown into the air cooling pipe 22 through the guiding effect of the air guide plate 25, and blown to the placement platform 26 through the air outlet 23. The air cooling device can quickly reduce the temperature of the welding part. If the high-temperature welding point has a slow natural cooling speed, it will extend the production cycle.

When the mainboard component is placed on the top of the placement platform 26, the clamping block 28 clamps the mainboard component under the elastic force of the clamping spring 29, so that it is fixed on the placement platform 26. The clamping block 28 prevents the mainboard from shaking during welding, avoiding problems such as cold welding and leaking welding. The clamping spring 29 can provide sufficient clamping force to firmly fix the mainboard at the welding position. The setting of the clamping spring 29 can ensure that mainboards of different sizes can be well fixed, thereby improving the adaptability and flexibility of the equipment.

[0043] The third embodiment is based on the first and second embodiments.

[0044] A first slider 33 is fixedly installed on the outer side of the fixed plate 31, and the hydraulic cylinder 32 and the first slider 33 are arranged in sequence. A transmission assembly 34 is slidably connected to the outer side of the first slider 33 through a slide rail.

A fixing clamp 38 is fixedly connected to the bottom of the transmission assembly 34, and a solder wire fixing pen 39 is clamped and installed at the bottom of the fixing clamp 38.

[0045] The outer side surface of the transmission component 34 is slidably connected to the electric soldering iron lifting component 35 through a slide rail. The arrangement of the transmission component 34 enables the solder wire and the electric soldering iron lifting component 35 to contact the mainboard when reaching the welding height to achieve welding.

[0046] The transmission assembly 34 includes a slide rail slider 341, which is slidably connected to the first slider 33 through a slide groove provided inside the slide rail slider 341, a pulley 342 is fixedly installed on the side of the slide rail slider 341, and the number of pulleys 342 is two, and a belt 344 is transmission-installed on the outer surface of the pulley 342, and the outer surface of the belt 344 is respectively clamped and installed with a first cassette mechanism 343 and a second cassette mechanism 345, the first cassette mechanism 343 is fixedly installed on the surface of the fixed plate 31, and the other end of the second cassette mechanism 345 is slidably installed inside the slide rail of the slide rail slider 341. When the slide rail slider 341 is raised or lowered, the pulley 342 is raised or lowered along with the slide rail slider 341, and the second cassette mechanism 345 is raised or lowered synchronously due to the transmission of the belt 344, driving the electric soldering iron lifting assembly 35 to rise or fall.

[0047] The soldering iron lifting assembly 35 includes a second slider 351, which is slidably connected to a slide groove set inside the slide rail slider 341. A fixed sleeve 352 is fixedly connected to the bottom of the second slider 351, and a soldering iron 353 is fixedly installed on the inner side of the fixed sleeve 352.

[0048] The tin discharge assembly 37 includes a fixing frame 371, which is fixedly installed at the bottom of the outer surface of the fixing plate 31. The inner side of the fixing frame 371 is rotatably connected to a reel 372 via a rotating shaft. The outer side of the reel 372 is wound with solder wire. A hole is opened inside the solder wire fixing pen 39, and the solder wire passes through the solder wire fixing pen 39 and extends to its bottom. The tin discharge assembly 37 makes the supply of solder wire more stable, avoiding interruption of the welding process due to untimely supply of solder wire.

[0049] The third embodiment is based on the first and second embodiments. Figures 1 to 10As shown, the fixing device 4 is fixedly installed at the bottom of the lifting device 3; the device realizes the automatic welding of the mainboard components and greatly improves the welding efficiency. The fixing device 4 includes a telescopic rod 41, which is fixedly connected to the bottom of the slide rail slider 341, and a fixed cover 43 is fixedly connected to the bottom of the telescopic rod 41.

The fixed cover 43 can form a relatively stable welding space, reduce the influence of external airflow on the welding process, thereby improving the stability and quality of welding. During the welding process, under the buffering effect of the buffer spring 42, the fixed cover 43 can press the mainboard components to achieve the fixing effect, and during welding, the fixed cover 43 can block the cooling air blown out of the air outlet 23. When the welding is completed, the lifting device 3 lifts the fixing device 4 and rises accordingly, and the cooling air blows to the welding point to achieve cooling.

[0050] When in use, the operator places the mainboard component on the top of the placement platform 26. Under the elastic force of the clamping spring 29, the clamping block 28 clamps the mainboard component to fix it. At this time, the first motor 14 is turned on, and the output end of the first motor 14 drives the screw rod 15 to rotate. The screw rod 15 and the second fixing block 18 move in a transmission cooperation manner. The first fixing block 17 is slidably connected to the outer surface of the slide bar 16.

[0051] When the second motor 21 is running, it drives the fan 24 to rotate and generate cooling air. The cooling air is guided by the air guide 25 and blown into the air cooling duct 22, and then blown to the placement platform 26 through the air outlet 23, so as to quickly reduce the temperature of the welding part and realize the cooling of the mainboard.

[0052] When the hydraulic cylinder 32 is working, the telescopic end of the hydraulic cylinder 32 drives the third fixed block 36 to rise and fall, the slide rail slider 341 slides on the outer side of the first slider 33 through the slide rail, and the pulley 342 rises and falls with the slide rail slider 341. Due to the transmission of the belt 344, the second cassette mechanism 345 rises and falls synchronously, driving the electric soldering iron lifting assembly 35 to rise and fall. The setting of the transmission assembly 34 makes the solder wire and the electric soldering iron lifting assembly 35 descend at different speeds, but they can finally contact the mainboard at the same position to achieve welding;

[0053] During the welding process, the fixing cover 43 can press the mainboard component to achieve the fixing effect under the buffering effect of the buffer spring 42, and the fixing cover 43 can block the cooling air blown out of the air outlet 23 during welding. When the welding is completed, the lifting device 3 lifts the fixing device 4 and the cooling air blows to the welding point to achieve cooling.

[0054] After the welding is completed, the first motor 14 is turned on. The mainboard placement component 2 is pushed out, and the mainboard is taken out to complete the operation.
