Description

Technical Field

[0001] This utility model relates to the field of surface mount welding technology, and in particular to a surface mount welding device. Background Technology

[0002] Post-placement soldering is a crucial step in surface mount technology (SMT). It involves heating solder paste to melt it, enabling electrical interconnection between the pins of electronic components and the pads on the printed circuit board (PCB). Currently, most surface mount soldering processes involve manual or robotic arm soldering using a soldering gun. Manual soldering is time-consuming and labor-intensive, while robotic arm soldering is more convenient. However, robotic arms can only adjust the position, and the angle of the soldering gun is fixed, making it impossible to tilt and solder corners. Therefore, we have introduced a post-placement soldering device. Utility Model Content

[0006] Preferably, the welding mechanism includes a support frame and a welding torch. A fixed frame is fixedly connected to the lower end of the support frame. The fixed frame has an arc-shaped structure. A sliding groove is opened at the front end of the fixed frame. A slider is slidably connected in the sliding groove.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A patch welding device includes a base 1, a patch body 6 is provided at the front of the upper end of the base 1, a rodless cylinder 2 is fixedly connected to the rear end of the base 1, an electric push rod 3 is fixedly connected to the upper part of the sliding end of the rodless cylinder 2, a cross frame 4 is fixedly connected to the telescopic end of the electric push rod 3, and a welding mechanism 5 is slidably connected inside the cross frame 4.

[0026] In this embodiment, the welding mechanism 5 includes a support frame 55 and a welding torch 57. A fixed frame 51 is fixedly connected to the lower end of the support frame 55. The fixed frame 51 has an arc-shaped structure. A sliding groove 52 is opened at the front end of the fixed frame 51. A slider 53 is slidably connected in the sliding groove 52. A second motor 54 is fixedly connected to the lower rear end of the support frame 55. A gear 56 is fixedly connected to the output end of the second motor 54. Anti-detachment plates 532 are fixedly connected to both the front and rear ends of the slider 53. A rack 531 is fixedly connected to the outer surface of the slider 53. A connecting frame 533 is fixedly connected to the front end of the anti-detachment plate 532 located at the front. The welding torch 57 is inserted and fixedly connected to the connecting frame 533. The two anti-detachment plates 532 are located at the front and rear ends of the fixed frame 51, respectively. The rack 531 is meshed with the gear 56.

[0027] In this embodiment, a No. 1 motor 41 is fixedly connected to the front end of the cross frame 4. The cross frame 4 has an internal hollow structure. A guide rod 43 is fixedly connected to the upper part of the inner wall of the cross frame 4. A threaded rod 42 is fixedly connected to the output end of the No. 1 motor 41. The threaded rod 42 is movably connected to the cross frame 4 through a bearing. The threaded rod 42 is threadedly connected to the support frame 55. The guide rod 43 is movably connected to the support frame 55 through an insertion.

[0028] It should be noted that this utility model describes a post-patch welding device. Specifically, the welding torch 57 and the connecting frame 533 are tightly fixed together. This fixing method ensures the synchronization of the two during movement and avoids welding deviations caused by relative displacement. The connecting frame 533 is also firmly connected to the slider 53, laying the foundation for subsequent transmission and adjustment. When the second motor 54 is started, the motor begins to run and outputs power, driving the gear 56 connected to it to rotate. The gear 56 meshes with the rack 531, which is carefully designed on the outer surface of the slider 53. This meshing transmission method has the characteristics of smooth transmission and high accuracy. Under the rotation of gear 56, slider 53 will adjust its position along a predetermined track within fixed frame 51. Since welding torch 57 is connected to slider 53 via connecting frame 533, the position change of slider 53 will directly drive welding torch 57 to adjust its angle. This angle adjustment function allows welding torch 57 to flexibly tilt to a suitable angle for welding operations according to different welding requirements, greatly improving the flexibility and efficiency of welding. It is especially suitable for workpieces with complex shapes and strict welding angle requirements. In addition, the support frame 55 and the threaded rod 42 in the cross frame 4 are connected by threads. Threaded connections have good self-locking properties. The high transmission precision ensures the stability of the support frame 55 during adjustment. The threaded rod 42 is tightly connected to the output end of the first motor 41. When the first motor 41 runs, it drives the threaded rod 42 to rotate. Under the transmission action of the thread, the support frame 55 adjusts its position back and forth along the axial direction of the threaded rod 42, thereby further expanding the range of motion of the welding torch 57 in the back and forth direction. At the same time, the cross frame 4 is installed at the telescopic end of the electric push rod 3. With its precise telescopic control capability, the electric push rod 3 can drive the cross frame 4 to achieve precise vertical movement, thereby enabling the welding torch 57 installed on the cross frame 4 to move accurately. It can also be adjusted in the vertical direction. Moreover, the electric push rod 3 is mounted on the rodless cylinder 2. The rodless cylinder 2 has the characteristics of smooth movement and long stroke. It can drive the electric push rod 3 and the entire welding torch 57 related components to move in a wide range in the left and right direction. Through the above series of mechanical connections and transmission designs, the welding torch 57 realizes multi-dimensional flexible adjustment in the vertical, left and right, front and back and angle directions. This all-round adjustment capability enables the welding torch 57 to easily cope with welding tasks in different positions and angles, greatly improving the convenience and adaptability of welding, and providing a strong guarantee for efficient and high-quality welding operations.
