Description

Technical Field

[0001] This utility model relates to the technical field of wave soldering equipment, specifically to a universal wave soldering carrier. Background Technology

[0002] Wave soldering is a soldering technology in the field of electronic manufacturing. It uses liquid solder to solder the pins of electronic components to the pads of a printed circuit board (PCB). Its main advantages are that it can solder multiple parts at once, improving production efficiency; it is suitable for mass production and has a low cost. In the existing technology, the PCBA boards to be soldered are of different sizes, so they cannot be fixed on the carrier, which leads to soldering failure due to the movement of the PCBA boards during the soldering process. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art that the PCBA boards to be soldered are of different sizes, which makes it impossible to fix them on the carrier, resulting in soldering failure due to the movement of the PCBA boards during the soldering process. Thus, a universal wave soldering carrier that can adapt to PCBA boards of different sizes is provided.

[0004] Therefore, this utility model provides a universal wave soldering carrier, including a mounting frame for placing PCBA boards and a plurality of positioning supports disposed within the mounting frame for positioning the PCBA boards. The positioning supports are arranged along the extension direction of the mounting frame. A transverse positioning frame and a longitudinal positioning frame for positioning the PCBA boards are also slidably disposed on the mounting frame. At least one support rod for preventing deformation of the PCBA boards is also disposed on the mounting frame. A guide device is disposed on the positioning support. One end of the support rod is slidably disposed within the guide device, and the other end extends in the opposite direction.

[0005] Furthermore: the transverse positioning frame and the longitudinal positioning frame are arranged perpendicularly to each other, and the mounting frame is provided with a longitudinal positioning groove for assisting the movement of the transverse positioning frame and a transverse positioning groove for assisting the movement of the longitudinal positioning frame.

[0006] Furthermore: a positioning bracket is fixed inside the mounting frame, and the positioning support rod array is arranged on the positioning bracket and the transverse positioning frame.

[0007] Furthermore: the guiding device includes a first guide rail disposed on the positioning bracket and a second guide rail disposed on the transverse positioning frame, and the support rod can be disposed within the first guide rail and / or the second guide rail.

[0008] The technical solution of this utility model has the following advantages:

[0009] 1. This utility model provides a universal wave soldering carrier. When dealing with PCBA boards of different models and sizes, the operator can manually adjust the horizontal positioning frame and the vertical positioning frame so that they are close to the side of the PCBA board. Then, the positions of the horizontal and vertical positioning frames are fixed, and finally, the positioning support rod is rotated so that the lower end face of the positioning support rod can abut against the upper end face of the PCBA board. Through the setting of the positioning support rod, the horizontal positioning frame, and the vertical positioning frame, the PCBA board can be positioned in a dual manner, avoiding soldering failure caused by the movement of the PCBA board during the soldering process. Therefore, the mounting frame in this embodiment, used in conjunction with the horizontal and vertical positioning frames, can be applied to PCBA boards of various sizes.

[0010] 2. The present invention provides a universal wave soldering carrier, wherein the mounting frame is connected to multiple support rods for preventing PCBA board deformation. The support rods are set on the back of the PCBA board and can effectively prevent the PCBA board from deforming after wave soldering. Attached Figure Description

[0023] Example

[0024] This embodiment provides a universal wave soldering carrier, including a mounting frame 11 for placing a PCBA board 1 and a plurality of positioning supports 12 disposed within the mounting frame 11 for positioning the PCBA board 1. The positioning supports 12 are arranged along the extension direction of the mounting frame 11. A transverse positioning frame 2 and a longitudinal positioning frame 3 for positioning the PCBA board 1 are also slidably disposed on the mounting frame 11. At least one support rod 13 for preventing deformation of the PCBA board 1 is also disposed on the mounting frame 11. A guide device 5 is disposed on the positioning bracket 4. One end of the support rod 13 is slidably disposed within the guide device 5, and the other end extends in the opposite direction.

[0025] The specific improvements mentioned above are as follows: Figure 1 and Figure 2As shown, compared to existing technologies, when dealing with PCBA boards 1 of different models and sizes, operators can manually adjust the horizontal positioning frame 2 and the vertical positioning frame 3 to ensure they are tightly against the side of the PCBA board 1. Then, the positions of the horizontal positioning frame 2 and the vertical positioning frame 3 are fixed. Finally, the positioning support rod 12 is rotated so that its lower end face abuts against the upper end face of the PCBA board 1. Through the arrangement of the positioning support rod 12, the horizontal positioning frame 2, and the vertical positioning frame 3, a dual positioning function is achieved for the PCBA board 1, preventing welding failure due to movement of the PCBA board 1 during the soldering process. Therefore, the mounting frame 11 in this embodiment, used in conjunction with the horizontal positioning frame 2 and the vertical positioning frame 3, is suitable for various sizes of PCBA boards 1, such as... Figure 5 As shown, the mounting frame 11 is connected to multiple support rods 13 to prevent deformation of the PCBA board 1. These support rods 13 are located on the back of the PCBA board 1 and effectively prevent PCBA board 1 from deforming after wave soldering. Figure 5 As shown, by setting the guide device 5, the support rod 13 can slide along the extension direction of the guide device 5, thereby customizing the position of the support rod 13 and preventing the PCBA board 1 from deforming after wave soldering.

[0026] Based on the above embodiments: the transverse positioning frame 2 and the longitudinal positioning frame 3 are arranged perpendicularly to each other, and the mounting frame 11 is provided with a longitudinal positioning groove 31 for assisting the movement of the transverse positioning frame 2 and a transverse positioning groove 21 for assisting the movement of the longitudinal positioning frame 3.

[0027] Based on the above embodiments: a positioning bracket 4 is fixed inside the mounting frame 11, and the positioning support rods 12 are arranged in an array on the positioning bracket 4 and the transverse positioning frame 2.

[0028] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, a positioning bracket 4 is provided on the side of the mounting frame 11. The positioning bracket 4 is parallel to the horizontal positioning frame 2 and perpendicular to the mounting frame 11. When placing the PCBA board 1, the two adjacent sides are pressed tightly against the mounting frame 11 and the positioning bracket 4. Then, the positioning support rod 12 is rotated so that the lower end face of the positioning support rod 12 abuts against the upper end face of the PCBA board 1, thereby fixing the position of the PCBA board 1 and facilitating subsequent soldering.

[0029] Based on the above embodiments: the guiding device 5 includes a first guiding rail 51 disposed on the positioning bracket 4 and a second guiding rail 52 disposed on the transverse positioning frame 2, and the support rod 13 can be disposed in the first guiding rail 51 and / or the second guiding rail 52.

[0030] The specific improvements mentioned above are as follows: Figure 5 As shown, the positioning bracket 4 is provided with 4-5 first guide rails 51, and the transverse positioning bracket 2 is provided with 4-5 second guide rails 52. During use, the operator can set the position of the support rod 13 according to the size of the PCBA board 1. The support rod 13 can be fixed in any of the first guide rails 51 or the second guide rails 52. After fixing, fastening nails are inserted into the support rod 13 to fix the position of the support rod 13. The fastening nails pass through the first guide rails 51 or the second guide rails 52 and are screwed into the support rod 13.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
