The utility model facilitates the fixing of the circuit board through the structural design of the fixing mechanism and the welding mechanism. It can automatically weld the wire and the circuit board, preventing the risk of burns caused by manual welding, speeding up work efficiency, and improving the safety of the device.

[0038] It is necessary to further explain that: after the circuit board body to be welded is transferred between the first welder 31 and the second welder 32 by the transmission belt 102, the driving mechanism 2 is started to drive the half gear 312 to reciprocate on the top of the rack 313, thereby driving the half gear 312 inside the first welder 31 and the second welder 32 to tilt to the left or right at the same time. When the half gear 312 tilts to the left, the roller 311 on the right side of the half gear 312 moves upward, thereby pushing the movable plate 305 and the slide rod 306 upward into the interior of the housing 304, further The welding module 307 at the top of the slide bar 306 inside the first welder 31 and the electronic component feeding module 314 at the bottom of the slide bar 306 inside the second welder 32 are driven to approach the circuit board body at the same time, so as to cooperate with each other to weld the electronic components on the circuit board body. When the half gear 312 tilts to the right, the roller 311 on the left side of the half gear 312 moves upward, thereby welding the electronic components on the circuit board body on the transmission belt 102 on the other side. The circuit board body on the transmission belt 102 needs to be arranged alternately according to the movement trajectory of the half gear 312.

[0039] like Figure 6 and Figure 7 As shown, the welding mechanism 3 includes a second column 301, a first positioning rod 302, a second positioning rod 303, a first welder 31, a second welder 32, a welding module 307 and an electronic component feeding module 314. The second column 301 is fixedly installed on one side of the transmission belt 102. The first positioning rod 302 is fixedly installed on one side of the second column 301. The second positioning rod 303 is also fixedly installed on one side of the second column 301. The second positioning rod 303 is arranged on the top of the first positioning rod 302. The first welder 31 and the second welder 32 are symmetrically arranged with the second column 301 as the center. The first welder 31 and the second welder 32 both include a housing 3 04, movable plate 305, slide bar 306, positioning plate 308, limiting column 309 and spring 310, the shell 304 inside the first welder 31 is fixedly installed on one side of the first positioning rod 302, the bottom of the shell 304 is movably installed with a movable plate 305, the top of the movable plate 305 is fixedly installed with a slide bar 306, the welding module 307 is arranged on the top of the slide bar 306, the top of the shell 304 is fixedly installed with a positioning plate 308, the bottom of the positioning plate 308 is provided with a limiting column 309, the bottom of the positioning plate 308 is also provided with a spring 310, the electronic component feeding module 314 is arranged at the bottom of the slide bar 306 inside the second welder 32.

[0040] The first welder 31 and the second welder 32 also include a roller 311, a half gear 312 and a rack 313. The roller 311 is movably connected to the bottom of the movable plate 305. The roller 311 is movably installed on one side of the half gear 312, and the roller 311 is symmetrically arranged with the half gear 312 as the center. The bottom of the half gear 312 is meshed with the rack 313, and the rack 313 is fixedly installed on one side of the second column 301.

[0041] The top of the limiting column 309 is fixedly connected to the bottom of the positioning plate 308, the bottom of the limiting column 309 is fixedly connected to the top of the movable plate 305, the top of the spring 310 is fixedly connected to the bottom of the positioning plate 308, the bottom of the spring 310 is fixedly connected to the top of the movable plate 305, and the sliding rod 306 is movably sleeved inside the positioning plate 308.

[0042] It needs to be further explained that: when it is necessary to drive the half gear 312 to perform reciprocating motion, the first pulley 205 is driven to rotate by starting the transmission belt 102, and the second pulley 207 is further driven to rotate by the belt 206. When the second pulley 207 rotates, the eccentric wheel 208 rotates at the same time, and drives the slider 209 to perform linear reciprocating motion in the left and right directions under the restriction of the first limit shaft 204 and the second limit shaft 211. When the slider 209 moves, the vertical rod 212 and the horizontal rod 213 perform linear reciprocating motion at the same time under the restriction of the limit block 216, and finally achieve the purpose of driving the half gear 312 inside the first welder 31 and the second welder 32 to move simultaneously.

[0043] The working principle and usage process of the present invention: During the use of the present invention, first, when the device is started, the circuit board body to be processed enters one side of the transmission belt 102 through the feeder 101, and the grooves on the left and right sides of the transmission belt 102 are driven by the driving device 104 to clamp and transport the circuit board body. Then the circuit board body enters the interior of the coating machine 103, and after the tin material is applied inside the coating machine 103, it enters the middle of the first welder 31 and the second welder 32 to prepare for welding processing.

[0044] Next, when it is necessary to drive the half gear 312 to do reciprocating motion, the first pulley 205 is driven to rotate by starting the transmission belt 102, and the second pulley 207 is further driven to rotate by the belt 206. When the second pulley 207 rotates, the eccentric wheel 208 rotates at the same time, and drives the slider 209 to do linear reciprocating motion in the left and right directions under the restriction of the first limit shaft 204 and the second limit shaft 211. When the slider 209 moves, the vertical rod 212 and the horizontal rod 213 do linear reciprocating motion at the same time under the restriction of the limit block 216, and finally achieve the purpose of driving the half gear 312 inside the first welder 31 and the second welder 32 to move simultaneously.

[0045] Finally, after the circuit board body to be welded is transferred to between the first welder 31 and the second welder 32 by the transmission belt 102, the driving mechanism 2 is started to drive the half gear 312 to reciprocate on the top of the rack 313, thereby driving the half gear 312 inside the first welder 31 and the second welder 32 to tilt to the left or right at the same time. When the half gear 312 tilts to the left, the roller 311 on the right side of the half gear 312 moves upward, thereby pushing the movable plate 305 and the slide rod 306 upward into the interior of the housing 304, further driving the first welder 31 and the second welder 32 to tilt to the left or right. The welding module 307 at the top of the slide bar 306 inside the welder 31 and the electronic component feeding module 314 at the bottom of the slide bar 306 inside the second welder 32 approach the circuit board body at the same time, thereby cooperating with each other to weld the electronic components on the circuit board body. When the half gear 312 tilts to the right, the roller 311 on the left side of the half gear 312 moves upward, thereby welding the electronic components on the circuit board body on the transmission belt 102 on the other side. The circuit board body on the transmission belt 102 needs to be alternately arranged according to the movement trajectory of the half gear 312.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
