[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] See also Figures 1 to 9 The present invention provides a technical solution: a welding device for computer hardware processing, comprising: a base 11, a conveying member 12 is mounted on the top of the base 11, a welding member 13 is arranged at the bottom of the conveying member 12, and a wire transmission member 14 is arranged on one side of the welding member 13, and a display screen 15 is fixed on the side of the conveying member 12;

[0034] The monitoring component 2 is also included. The monitoring component 2 is arranged on the other side of the welding piece 13. The monitoring component 2 is pressed against the surface of the motherboard to be welded, and the distance between the welding piece 13 and the motherboard is monitored and determined by the monitoring component 2.

[0035] The speed regulating component 5 and the driving component 6 are arranged on the top of the monitoring component 2. The outer sleeve of the speed regulating component 5 is provided with a coil 71, and the rotation speed of the coil 71 is adjusted according to the distance monitored by the monitoring component 2;

[0036] The regulating component 1 3 and the regulating component 2 4 are arranged inside the monitoring component 2, and the current of the heating component of the welding part 13 and the parameters of the display screen 15 are adjusted according to the distance monitored by the monitoring component 2;

[0037] The connecting component 8 is arranged on the top of the speed regulating component 5. The speed regulating component 5 is stabilized by the connecting component 8. The distance between the welding part 13 and the main board is monitored by the monitoring component 2. When the part to be welded is smaller, the control mechanism adjusts the distance between the welding part 13 and the main board to be smaller. According to the distance monitored by the monitoring component 2, the rotation speed of the coil 71 is directly adjusted through the speed regulating component 5, so that the conveying speed of the tin bar line 72 is adjusted according to the size of the area of ​​the part to be welded, which is convenient for the welding operation of the small area patch to be welded and improves the welding effect.

[0038] The monitoring component 2 includes a connecting tube 21 fixed on the side of the welding part 13, and a cavity 22 is opened inside the connecting tube 21, and a pressure plate 23 is inserted inside the cavity 22. The pressure plate 23 presses on the surface of the main board to be welded. When the welding part 13 moves downward, the pressure plate 23 retracts into the cavity 22 until the welding part 13 reaches the required welding position. The degree of descent of the welding part 13 is judged by the length of the pressure plate 23 extending out of the cavity 22, thereby judging the distance between the welding part 13 and the point to be welded, so as to facilitate the subsequent regulation of the pay-off speed of the tin strip line 72.

[0039] A pressing block 24 is fixed to the bottom of the pressing plate 23, and a rotating ball 25 is embedded in the pressing block 24. The rotating ball 25 presses against the surface of the motherboard to be welded, reducing the friction between the pressing block 24 and the motherboard, making it easier for the rotating ball 25 to slide on the surface of the motherboard.

[0040] The adjusting component 3 includes a sliding rheostat 31 fixed to one side of the inner wall of the cavity 22, and a sliding piece 32 is sleeved on the outside of the sliding rheostat 31, and the side of the sliding piece 32 is fixed to the surface of the pressing plate 23. When the pressing plate 23 moves downward with the welding part 13, the pressing plate 23 is pressed by the main board, and the pressing plate 23 drives the sliding piece 32 to move vertically upward synchronously. When the distance between the welding part 13 and the point to be welded is large, the extended length of the pressing plate 23 is large, and the sliding piece 32 is at the lower end of the outer wall of the sliding rheostat 31. At this time, the resistance value of the sliding rheostat 31 is the smallest, and the current value transmitted to the welding part 13 is large. The greater the heating temperature of the welding part 13, the greater the distance between the welding part 13 and the point to be welded, the larger the area of ​​the point to be welded, and the greater the descending speed of the tin wire. At this time, the heating temperature of the welding part 13 is large, which is convenient for heating the rapidly descending tin wire and is conducive to the melting of the tin wire.

[0041] The adjustment component 24 includes a sliding rheostat 241 fixed on one side of the inner wall of the cavity 22, and a slider 242 is provided on the outside of the sliding rheostat 241. The side of the slider 242 is fixed on the surface of the pressure plate 23. The movement of the pressure plate 23 drives the slider 242 to move synchronously. When the pressure plate 23 gradually moves up, it indicates that the distance between the welding part 13 and the main board is gradually reduced. At this time, the slider 242 moves up on the surface of the sliding rheostat 241, and the resistance value changes. When the resistance value changes, the parameters are displayed on the display screen 15. The operator can more accurately judge the distance between the welding part 13 and the main board by observing the parameters displayed on the display screen 15.

[0042] The speed regulating assembly 5 includes a push plate 51 fixed on the top of the pressure plate 23, and a pulley 52 is arranged on the top of the push plate 51, and a pulley 53 is arranged on the side of the push plate 51. The bottom of the pulley 53 is fixed on the surface of the connecting cylinder 21. A pull rope 54 is wound around the outside of the pulley 52 and the pulley 53. One end of the pull rope 54 is fixed to the surface of the connecting cylinder 21, and the other end of the pull rope 54 is fixed to the connecting block 55. The two sides of the top of the connecting block 55 are connected to the ring 57 through the pull rope 56. The inner wall of the ring 57 is rotatably connected There is a connecting ring 58. When the pressure plate 23 moves upward, the pressure plate 23 drives the pulley 1 52 to move upward synchronously through the push plate 51. The pulley 1 52 pushes the pull rope 1 54, so that the pull rope 1 54 is tightened, and the top of the pull rope 1 54 moves downward. The pull rope 1 54 drives the pull rope 2 56 to move downward synchronously through the connecting block 55. The pull rope 2 56 pulls the ring 57 downward, and the ring 57 drives the connecting ring 58 and the clamping ring 59 to move downward. The upward movement of the pressure plate 23 is convenient for directly pulling the connecting ring 58 to move downward, which is beneficial to the subsequent adjustment of the rotation speed of the coil 71.

[0043] The inner wall of the connecting ring 58 is slidably connected with a snap ring 59 through a slider 91. A sliding opening 92 cooperating with the slider 91 is provided inside the connecting ring 58. A second spring 93 is fixed on the side of the slider 91, and the end face of the second spring 93 is fixed on the inner wall of the sliding opening 92. When the connecting ring 58 moves downward, the connecting ring 58 drives the snap ring 59 to move synchronously. Under the extrusion of the connecting ring 58, the snap ring 59 moves obliquely upward on the surface of the rotating wheel 61. The slider 91 slides inside the sliding opening 92. The second spring 93 is in a stretched and force-accumulated state. At this time, the snap ring 59 and the rotating wheel 61 are pressed against each other. As the diameter of the pressure increases, the rotation speed of the retaining ring 59 decreases, and the retaining ring 59 drives the rotation speed of the connecting ring 58 to decrease, and the connecting ring 58 drives the rotation speed of the coil 71 to decrease synchronously. When the connecting ring 58 moves up, the retaining ring 59 returns to its initial position under the pull of the spring 2 93. Therefore, when the welding part 13 is closer to the mainboard patch, the rotation speed of the coil 71 is smaller, and the tinning speed of the coil 71 is smaller, so that the moving speed of the tin strip line 72 can be adjusted according to the distance between the welding part 13 and the patch, which is beneficial to the welding of small-area welding points and improves the welding effect.

[0044] The driving assembly 6 includes a rotating wheel 61 inserted into the inside of the ring 57. The outer wall of the rotating wheel 61 is tightly pressed against the retaining ring 59. The end face of the rotating wheel 61 is fixedly connected to the output shaft of the motor 62. A fixing plate 63 is fixed to the outer wall of the motor 62, and the side of the fixing plate 63 is fixed to the surface of the conveying member 12. The rotating wheel 61 is driven to rotate by the motor 62, which is convenient for indirectly driving the coil 71 to be retracted and released, thereby realizing the conveying operation of the coil 71.

[0045] A tin wire 72 is wound around the outside of the coil 71, one end of the tin wire 72 is fixed to the surface of the coil 71, and the other end of the tin wire 72 is inserted into the inside of the wire conveying member 14. The automatic transportation of the tin wire 72 is achieved through the rotation of the coil 71, replacing the manual pushing of the tin wire 72, which is more convenient and intelligent.

[0046] Embodiment 2

[0047] The connecting assembly 8 includes a fixed block 81 fixed to the top of the ring 57, and a plug rod 82 is fixed to the top of the fixed block 81, a spring 83 is sleeved on the outside of the plug rod 82, the top of the spring 83 is pressed against the inner wall of the sleeve 84, the sleeve 84 is sleeved on the outside of the plug rod 82, and a connecting plate 85 is fixed on the top of the sleeve 84, and the side of the connecting plate 85 is fixed to the surface of the conveying member 12. When the pull rope 2 56 pulls the ring 57 downward, the ring 57 drives the fixed block 81 to move downward synchronously, and the fixed block 81 drives the plug rod 82 to move downward synchronously. At this time, the spring 1 83 is in a stretched and force-accumulating state. When the pull rope 2 56 on the ring 57 is released, the ring 57 moves up under the pull of the spring 1 83, and the ring 57 returns to its initial position. Through this design, the movement of the ring 57 is supported and limited, and the movement of the ring 57 is stabilized.
