Description

Technical Field

[0001] This utility model relates to the field of wave soldering carrier technology, and in particular to a wave soldering carrier for electronic equipment processing. Background Technology

[0002] Wave soldering is a process in which the soldering surface of a circuit board comes into direct contact with high-temperature liquid solder to achieve the soldering purpose. The high-temperature liquid solder is kept on an inclined plane, and a special device makes the liquid solder form waves, hence the name "wave soldering". Its main material is solder bar.

[0003] Wave soldering is frequently used in the processing of electronic equipment. For example, Chinese utility model patent with publication number CN213702103U includes a mounting groove and a carrier. Bearings are provided on both sides of the inner sidewalls of the mounting groove. A threaded shaft is movably mounted inside the mounting groove through the bearings. A limit block is provided at the middle position of the threaded shaft. The surface of the threaded shaft is provided with two reverse threads. The two reverse threads on the surface of the threaded shaft are symmetrically distributed with the limit block as the symmetrical point.

[0004] This patent can make the device have good fixing effect and strong adaptability by setting a series of structures. However, when fixing the welded parts, the operator needs to turn four knobs to make four screws rotate, so that four pressure plates can press down on the four ends of the part to be welded for further fixing. The overall operation process is relatively cumbersome and the fixing efficiency is insufficient when performing batch welding. In view of this, we propose a wave soldering carrier for electronic equipment processing. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a wave soldering carrier for electronic equipment processing, which can solve the problem that the overall process is cumbersome and time-consuming when fixing.

[0007] Preferably, the fixing component includes a rotating rod, which is rotatably connected to the upper surface of the carrier vertical plate. A first gear is sleeved on the outer surface of the rotating rod, and a first gear is also fixedly connected to the upper end of the threaded rod. The two first gears are meshed together. An external toothed tube is provided on the left side surface of the workbench, and the right end of the external toothed tube extends through the right side surface of the carrier and is rotatably connected to the right side vertical plate of the workbench.

[0008] Preferably, the carrier on the right side has a cavity inside, the lower end of the rotating rod rotatably penetrates into the cavity, the outer surface of the rotating rod is fitted with a first worm gear, and the inner wall of the right side of the cavity is rotatably connected to a first worm.

[0009] Preferably, a second gear is fixedly connected to the left end of the first worm, the outer surface of the second gear meshes with the outer toothed tube, and the second worm is rotatably connected to the inner walls of the front and rear sides of the cavity.

[0010] Preferably, the outer surface of the second worm gear meshes with the first worm wheel, the outer surface of the second worm gear is fitted with the second worm wheel, the outer surface of the second worm wheel meshes with the first worm gear, and a baffle is fixedly connected to the right side surface of the left-side carrier, the right side surface of the baffle slidingly penetrates into the interior of the right-side carrier.

[0011] Preferably, a drive box is fixedly connected to the right side surface of the worktable, and the right ends of the two bidirectional threaded rods rotatably penetrate into the interior of the drive box.

[0013] Preferably, a fourth gear is fitted on the outer surface of the drive shaft, and the right end of the drive shaft rotates through the right side surface of the drive housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The wave soldering carrier processed by the electronic device, when fixing the workpiece, places the workpiece on top of two carriers, and then drives the threaded rod to rotate using the fixing component. Since the movement trajectory of the threaded sleeve is restricted by the sliding plate and the sliding groove, the threaded sleeve will move vertically when the threaded rod is driven to rotate. When the threaded sleeve moves, it drives the pressure plate to press the four corners of the workpiece, thereby completing the fixing and clamping of the workpiece. Through the above structure, when fixing the workpiece, the four pressure plates can be driven to descend at the same time, thereby effectively improving the clamping and fixing efficiency, reducing the complexity of the overall fixing process, and reducing the workload of the staff.

[0016] (2) The wave welding carrier processed by the electronic device drives the fourth gear to rotate synchronously through the rotating drive shaft. When the fourth gear rotates, it drives the two third gears to rotate synchronously. Then, the two third gears drive the two bidirectional threaded rods to rotate synchronously. Since each carrier is connected to the two bidirectional threaded rods through two threaded sleeves, the movement trajectory is mutually restricted. Therefore, when the bidirectional threaded rods rotate, they will drive the two carriers to move in opposite directions synchronously. Through the above structure, the baffle can be used to block the welding residue during wave welding, so as to prevent the residue from falling onto the lower bidirectional threaded rod and thus causing the bidirectional threaded rod to be obstructed.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a wave soldering carrier for electronic equipment processing, including a worktable 1, which is U-shaped. Two bidirectional threaded rods 2 are rotatably connected between two vertical plates of the worktable 1. Two carriers 3 are arranged on the worktable 1, and two threaded sleeves 4 are fixedly connected to the lower surfaces of the two carriers 3 respectively. The four threaded sleeves 4 are threaded onto the opposite threads of the two bidirectional threaded rods 2. Both carriers 3 are L-shaped and mirror images of each other. Sliding grooves 5 are respectively opened on the adjacent side surfaces of the vertical plates of the two carriers 3. Mounting plates 6 are fixedly connected to the adjacent side surfaces of the vertical plates of the two carriers 3 respectively. Threaded rods 7 are arranged on the mounting plates 6. The lower ends of the threaded rods 7 rotatably pass through the lower surface of the mounting plates 6. Threaded sleeves 8 are threadedly fitted onto the outer surface of the threaded rods 7. A sliding plate 9 is fixedly connected, extending into the interior of the sliding groove 5 and slidably connected to it. A pressure plate is fixedly connected to the lower surface of the threaded sleeve 8. A fixing component is provided on the carrier 3. When fixing the weldment, the weldment is placed above the two carriers 3, and then the threaded rod 7 is driven to rotate by the fixing component. Since the movement trajectory of the threaded sleeve 8 is restricted by the sliding plate 9 and the sliding groove 5, the threaded sleeve 8 will move vertically in sync when the threaded rod 7 is driven to rotate. When the threaded sleeve 8 moves, it drives the pressure plate to press against the four corners of the weldment, thereby completing the fixing and clamping of the weldment. Through the above structure, when fixing the weldment, four pressure plates can be driven to descend simultaneously, thereby effectively improving the efficiency of clamping and fixing, reducing the complexity of the overall fixing process, and reducing the workload of the workers.

[0027] Furthermore, the fixing assembly includes a rotating rod 10, which is rotatably connected to the upper surface of the vertical plate of the carrier 3. A first gear 11 is sleeved on the outer surface of the rotating rod 10. The upper end of the threaded rod 7 is also fixedly connected to a first gear 11. The two first gears 11 are meshed together. An external toothed tube 12 is provided on the left side surface of the workbench 1. The right end of the external toothed tube 12 extends through the right side surface of the carrier 3 and is rotatably connected to the right vertical plate of the workbench 1. A cavity 13 is provided inside the right side of the carrier 3. The lower end of the rotating rod 10 rotatably extends into the cavity 13. A first worm gear 14 is sleeved on the outer surface of the rotating rod 10. A first worm 15 is rotatably connected to the right inner wall of the cavity 13. A second gear 16 is fixedly connected to the left end of rod 15. The outer surface of the second gear 16 meshes with the outer toothed tube 12. A second worm 17 is rotatably connected to the inner walls of the front and rear sides of cavity 13. The outer surface of the second worm 17 meshes with the first worm wheel 14. A second worm wheel 18 is sleeved on the outer surface of the second worm 17. The outer surface of the second worm wheel 18 meshes with the first worm 15. A baffle 19 is fixedly connected to the right surface of the left carrier 3. The right surface of the baffle 19 slides through the interior of the right carrier 3. A drive box 20 is fixedly connected to the right surface of the workbench 1. The right ends of the two bidirectional threaded rods 2 rotatably penetrate into the interior of the drive box 20. The right ends of the two bidirectional threaded rods 2 are respectively fixed A third gear 21 is fixedly connected to the inner wall of the drive housing 20, and a drive shaft 22 is fixedly connected to it. A fourth gear 23 is fitted on the outer surface of the drive shaft 22. The right end of the drive shaft 22 rotates through the right side surface of the drive housing 20. By rotating the external gear tube 12, the external gear tube 12 synchronously drives the second gear 16 to rotate. When the second gear 16 rotates, it synchronously drives the first worm 15 to rotate. Then, the first worm 15 synchronously drives the second worm 17 to rotate through the second worm wheel 18. When the second worm 17 rotates, the first worm wheel 14 drives the rotating rod 10 to rotate. When the rotating rod 10 rotates, the two first gears 11 work together to drive the threaded rod 7. At the same time, the two vehicles are in operation. When adjusting the spacing of 3, the fourth gear 23 is driven to rotate synchronously by rotating the drive shaft 22. When the fourth gear 23 rotates, it will drive the two third gears 21 to rotate synchronously. In turn, the two third gears 21 will drive the two bidirectional threaded rods 2 to rotate synchronously. Since each carrier 3 is connected to the two bidirectional threaded rods 2 through two threaded sleeves 4, they restrict each other's movement trajectory. Therefore, when the bidirectional threaded rods 2 rotate, they will drive the two carriers 3 to move in opposite directions synchronously. Through the above structure, the baffle 19 can be used to block the welding residue during wave welding, so as to prevent the residue from falling onto the lower bidirectional threaded rods 2 and thus causing the bidirectional threaded rods 2 to be obstructed.

[0028] Working principle: When fixing the weldment, the weldment is placed above two carriers 3, and then the threaded rod 7 is driven to rotate by the fixing assembly. Since the movement trajectory of the threaded sleeve 8 is restricted by the sliding plate 9 and the sliding groove 5, the threaded rod 7 is driven to rotate, which in turn drives the threaded sleeve 8 to move vertically. When the threaded sleeve 8 moves, it drives the pressure plate to press the four corners of the weldment, thereby completing the fixing and clamping of the weldment. By rotating the external gear tube 12, the external gear tube 12 drives the second gear 16 to rotate. When the second gear 16 rotates, it drives the first worm 15 to rotate. The first worm 15 drives the second worm 17 to rotate through the second worm wheel 18. When the second worm 17 rotates, the first worm wheel 14 drives the rotating rod 10 to rotate. When the rotating rod 10 rotates, the two first gears 11 work together to drive the threaded rod 7. At the same time, when adjusting the distance between the two carriers 3, the drive shaft 22 is rotated, which in turn drives the fourth gear 23 to rotate. When the fourth gear 23 rotates, it drives the threaded rod 7 to rotate. The first step drives the two third gears 21 to rotate, which in turn drives the two bidirectional threaded rods 2 to rotate synchronously. Since each carrier 3 is connected to the two bidirectional threaded rods 2 through two threaded sleeves 4, their movement trajectories are mutually restricted. Therefore, when the bidirectional threaded rods 2 rotate, they will synchronously drive the two carriers 3 to move in opposite directions. It should be noted that the external gear tube 12 and the drive shaft 22 are two independent operating components that do not interfere with each other. The operator can adjust the distance between the two carriers 3 according to the actual size of the workpiece to be welded by first rotating the drive shaft 22 to make it match the length of the workpiece. Then, by rotating the external gear tube 12, the four pressure plates are driven to descend synchronously to press the four corners of the workpiece. Since the external gear tube 12 and the drive shaft 22 control the distance adjustment and pressing action respectively, there is no mechanical linkage between the two. Therefore, after the distance adjustment is completed, the pressing action can still be carried out independently, ensuring that the pressure plates can reliably press the workpieces of different sizes. This solves the problem of low fixing efficiency and difficulty in adapting to workpieces of different sizes mentioned in the background technology.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
