Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically a shielding mechanism for PCBA soldering protection. Background Technology

[0002] With precise protection during the PCBA soldering process as its core, this solution is applicable to the electronics manufacturing field and solves the problem of non-soldering areas being easily damaged by high temperatures and solder splatter during PCBA soldering.

[0003] A search revealed existing technology (application number: CN106964864A), which describes a "welding shielding device with a fixing function." This utility model includes a shielding plate and a base box. The shielding plate is fixedly connected to the rear side wall of the base box and is arc-shaped, curving towards the base box. A flexible metal tube is fixedly connected to the front side wall of the base box, and a welding mask is inserted into the opening of the flexible metal tube. The welding mask is fixedly connected to the flexible metal tube by a clamping ring set at the opening of the flexible metal tube. A collection groove is formed on the upper surface of the base box. A fixing belt is fixedly connected to the rear side wall of the base box, and a belt fixing buckle is provided on the front side wall of the base box. The fixing belt and the belt fixing buckle are fixedly connected.

[0004] However, while existing technologies can effectively move the welding mask via flexible metal hoses, making it convenient to use, and shielding plates can block welding fumes, thus optimizing the environment, and fixing belts can improve the stability of welding materials during welding, there are still some shortcomings: the lack of shielding of welding materials generated during welding can damage non-welding areas. This device isolates and protects non-welding areas through protective shells of different shapes and sizes. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, this embodiment provides a shielding mechanism for PCBA soldering protection, comprising: a base 1 for supporting components; a moving component including a slide rail 2 arranged on the base 1, a placement plate 3 slidably connected to the slide rail 2, and a connecting block 6 fixedly connected to the bottom of the placement plate 3; a fixing component including a clamping block 8 slidably connected to the placement plate 3; an elastic clamping component including a clamping block 9 slidably connected to the placement plate 3; a lifting component including a cylinder 11 arranged on the base 1, and a support frame 13 welded to the output end of the cylinder 11; and a rotating component including a disc 14 rotatably connected to the support frame 13, and a connecting rod 15 disposed at the bottom of the disc 14, wherein a limit groove is formed inside the connecting rod 15.

[0031] In this embodiment, the base 1 supports each component, the moving component moves in position by sliding the placement plate 3 on the slide rail 2, the fixing component and the elastic clamping component fix the PCBA board together, the lifting component drives the support frame 13 to rise and fall by the cylinder 11, and the rotating component drives the disc 14 to rotate by rotating the connecting rod 15, so as to realize the support, movement, fixing and lifting and rotation adjustment of the shielding components of the PCBA board.

[0032] Specifically, the moving component includes: a drive motor 4, which is arranged on the base 1; and a threaded rod 5, which is rotatably connected to the base 1 and threadedly connected to the connecting block 6, and connected to the output shaft of the drive motor 4.

[0033] The drive motor 4 drives the threaded rod 5 to rotate. The threaded rod 5 drives the connecting block 6 and the placement plate 3 to move along the slide rail 2 through the threaded transmission, so as to realize the automatic horizontal movement of the placement plate 3 and adjust the horizontal position of the PCBA.

[0034] Specifically, the fixing component includes: a threaded rod 7, which is rotatably connected to the placement plate 3, and the threads on its surface are symmetrically arranged, and it is threadedly connected to the clamping block 8.

[0035] As a preferred implementation, rotating the threaded rod 7 uses the symmetrical reverse threads to drive the two clamping blocks 8 to move relative to or in opposite directions, thereby achieving clamping and fixing of PCBAs of different sizes.

[0036] Example 2

[0037] Specifically, the elastic clamping assembly includes a spring 10, one end of which is connected to the placement plate 3 and the other end of which is connected to the clamping block 9.

[0038] It should be noted that the elastic force of the spring 10 pushes the clamping block 9 to move towards the PCBA, which works with the clamping block 8 to clamp the PCBA and enhance the stability of the PCBA fixation.

[0039] Specifically, the lifting assembly includes a telescopic column 12, which is arranged on one side of the support frame 13 for guiding.

[0040] In a preferred embodiment, when the cylinder 11 extends and retracts to drive the support frame 13 to rise and fall, the telescopic column 12 extends and retracts synchronously, restricting the direction of movement of the support frame 13, ensuring the stability of the support frame 13 during the rising and falling process, and preventing deviation.

[0041] Example 3

[0042] Specifically, the rotating assembly includes: a rotating shaft 16, slidably connected to a connecting rod 15; a gear set 17, arranged at the bottom of the rotating shaft 16; and a drive motor 18, whose output shaft is connected to the gear set 17 to provide power.

[0043] In addition, the drive motor 18 drives the rotating shaft 16 to rotate through the gear set 17. The rotating shaft 16 drives the connecting rod 15 and the disc 14 to rotate, thereby realizing the rotation adjustment of the shielding component to adapt to different welding position requirements.

[0044] Specifically, the rotating shaft 16 is provided with a key 19, and the key 19 is slidably connected to the limiting groove on the connecting rod 15.

[0045] In this embodiment, the key 19 slides in the limiting groove, so that the rotating shaft 16 can both drive the connecting rod 15 to rotate and move axially relative to the connecting rod 15, ensuring the power transmission between the rotating shaft 16 and the connecting rod 15, while allowing the two to rise and fall relative to each other.

[0046] In use, the user places the PCBA board on the placement plate 3, where the PCBA board is fixed by the clamping blocks 9 under the action of the springs 10 on both sides. At this time, the user rotates the threaded rod 7 to drive the clamping block 8 to center and clamp. The user holds the welding gun and starts the drive motor 18 to drive the gear set 17 to rotate, thereby driving the rotating shaft 16 to rotate. The key 19 on the rotating shaft 16 cooperates with the limiting groove on the connecting rod 15 to rotate. When the position to be protected is aligned with the position on the PCBA board, the user starts the drive motor 4 to drive the threaded rod 5 to rotate, thereby driving the connecting block 6 threaded to the threaded rod 5. This causes the placement plate 3 to slide on the slide rail 2 and move to the bottom of the disc 14. At this time, the cylinder 11 starts to drive the disc 14 to move, with the connecting rod 15 sliding on the rotating shaft 16, thereby clamping the position to be protected for welding. The disc 14 is equipped with four sets of different sizes and positions.

[0047] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
