[0006] To solve the above technical problems, the utility model is realized by the following technical schemes:

[0007] This utility model relates to a universal reflow soldering insert fixture, comprising a workbench with a reflow soldering insert placement slot inside. A reflow soldering insert clamping device is located on the top of the workbench. The clamping device includes an electrically operated telescopic rod, the bottom of which is fixedly connected to the inside of the reflow soldering insert placement slot. A rotating shaft is fixedly connected to the telescopic end of the electric telescopic rod. A connecting strip is rotatably connected to the circumferential surface of the rotating shaft. A rotating rod one is rotatably connected to the side of the connecting strip. A support rod is fixedly connected to the circumferential surface of the rotating rod one. A rotating rod two is rotatably connected to the bottom of the support rod. A force-bearing block is fixedly connected to the circumferential surface of the rotating rod two. The bottom of the force-bearing block is fixedly connected to the inside of the reflow soldering insert placement slot. A sliding groove is provided on the top of the workbench. A rotating shaft is fixedly connected to the side of the support rod, and a clamping block is fixedly connected to the circumferential surface of the rotating shaft.

[0008] Furthermore, the clamping block has an internal movable groove, and a fixing pin passes through the side of the clamping block. The circumferential surface of the fixing pin is slidably connected to the inner wall of the clamping block. The function of the fixing pin is to clamp and fix the soldered components.

[0009] Furthermore, a spring is fixedly connected to the side of the fixing pin, and the end of the spring away from the fixing pin is fixedly connected to the inner wall of the movable groove. A torsion spring is fixedly connected to the circumferential surface of the rotating shaft, and the end of the torsion spring away from the rotating shaft is fixedly connected to the side of the clamping block. The function of the spring is to allow the fixing pin to reset when no reflow soldering plug is pressing the fixing pin. The function of the torsion spring is to allow the clamping block to reset when it no longer clamps the reflow soldering plug.

[0010] Furthermore, the number of each of the connecting bar, rotating rod one, support rod, rotating rod two, force-bearing block, slide groove, rotating shaft, clamping block, movable groove, fixing pin, elastic spring, and torsion spring is set to two, and they are symmetrical to each other along the vertical central axis of the worktable. The purpose of setting the number of each of the connecting bar, rotating rod one, support rod, rotating rod two, force-bearing block, slide groove, rotating shaft, clamping block, movable groove, fixing pin, elastic spring, and torsion spring to two, and symmetrical to each other along the vertical central axis of the worktable, is to better clamp and fix the welded reflow soldering inserts.

[0011] Furthermore, a reflow soldering insert ejection device is provided on the top of the workbench. The reflow soldering insert ejection device includes a push plate, the front side of which is fixedly connected to the back side of the electric telescopic rod. A hydraulic cylinder is fixedly connected to the inner wall of the reflow soldering insert placement slot. The top of the hydraulic cylinder is fixedly inserted through the top of the workbench. A force-bearing rod is slidably connected to one end of the hydraulic cylinder via a piston. A hydraulic rod is slidably connected to the other end of the hydraulic cylinder via another piston. A push plate is fixedly connected to the front side of the hydraulic rod. A storage slot is provided on the top of the workbench. A reflow soldering insert collection box is slidably connected inside the storage slot. The push plate is used to eject the soldered reflow soldering insert from the soldering area. The reflow soldering insert collection box is used to collect the ejected soldered reflow soldering insert.

[0012] Furthermore, a return spring is fixedly connected to the circumferential surface of the force-bearing rod. The end of the return spring away from the force-bearing rod is fixedly connected to the top of the hydraulic cylinder. The function of the return spring is to allow the force-bearing rod to reset when the push plate stops pushing it.

[0013] Furthermore, the top of the force-bearing rod is located on the displacement trajectory of the push plate, and the bottom of the push plate is located above the reflow soldering plug collection box. The purpose of the top of the force-bearing rod being located on the displacement trajectory of the push plate is to push the force-bearing rod when the push plate moves.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model achieves this by having the electric telescopic rod's telescopic end move in conjunction with the internal components of the reflow soldering insert clamping device, including the rotating shaft, connecting bar, rotating rod one, support rod, rotating rod two, force-bearing block, slide groove, rotating shaft, and clamping block. When the rotating shaft moves upward, the connecting bar, through rotating rod one, causes the support rod to move along rotating rod two through the slide groove towards the center of the worktable. When the support rod moves towards the center, it drives the rotating shaft to move. When the rotating shaft moves, it drives the clamping block to move. This ensures that when the fixing pin moves to the appropriate position, it touches the reflow soldering insert to be soldered, allowing the fixing pin and clamping block to clamp the reflow soldering insert being soldered on the worktable.

[0016] 2. This utility model utilizes the movement of the telescopic end of the electric telescopic rod in conjunction with the internal components of the reflow soldering insert ejection device, including the push plate, hydraulic cylinder, force rod, hydraulic rod, push plate, storage tank, and reflow soldering insert collection box. This achieves the following: when the push plate moves downwards, it pushes the force rod. When the push plate pushes the force rod, the force rod moves into the hydraulic cylinder. As the force rod moves into the hydraulic cylinder, the hydraulic rod moves outwards due to the squeezing force of the moving force rod. This outward movement of the hydraulic rod drives the push plate outwards, allowing the moved push plate to eject the welded reflow soldering insert from the welding area and into the reflow soldering insert collection box.

[0032] A specific application of this embodiment is as follows: When it is necessary to use this device to solder components, the reflow soldering insert clamping device 3 can be used to clamp the components. By activating the electric telescopic rod 31, when the telescopic end of the electric telescopic rod 31 moves upward, it can drive the rotating shaft 32 to move upward. When the rotating shaft 32 moves upward, it will use the connecting bar 33 to drive the support rod 35 along the rotating rod 36 through the slide groove 38 to the middle of the worktable 1 via the rotating rod 34. When the support rod 35 moves to the middle, it can drive the rotating shaft 39 to move. When the rotating shaft 39 moves, it will drive the clamping block 310 to move. When the clamping block 310 moves, it will drive the fixing pin 312 to move. When the fixing pin 312 moves to the appropriate position, it will touch the reflow soldering insert to be soldered, thereby clamping the reflow soldering insert to be soldered. Through the action of the movable groove 311 and the elastic spring 313, reflow soldering inserts of different shapes can be clamped.

[0033] The movement of the electric telescopic rod 31 can drive the reflow soldering insert ejection device 4. When the reflow soldering insert is completed, the telescopic end of the electric telescopic rod 31 moves downward. When the telescopic end of the electric telescopic rod 31 moves downward, it can drive the push plate 41 to move downward. When the push plate 41 moves downward, it will push the force rod 43. When the push plate 41 pushes the force rod 43, the force rod 43 will move into the hydraulic cylinder 42. When the force rod 43 moves into the hydraulic cylinder 42, the hydraulic rod 44 will move out of the hydraulic cylinder 42 due to the squeezing force of the force rod 43. When the hydraulic rod 44 moves outward, it will drive the push plate 45 to move outward. Thus, the outward-moving push plate 45 can push the completed reflow soldering insert into the reflow soldering insert collection box 47.
