[0002] PCBA (Printed Circuit Board + Assembly) refers to the entire process of a PCB blank board after SMT mounting or DIP plug-in. Since the circuit board will have flux, various halogens and other residues attached to it after the patch, some elements in these residues will chemically react with the pads (copper) on the circuit board, thereby corroding the pads of the circuit board and causing electronic product failures. Therefore, the PCBA board needs to be cleaned after SMD (surface mount) to avoid corrosion from the residues.
[0003] However, in the electronics industry, due to the large and small, thick and thin PCBA boards commonly used, traditional cleaning equipment needs to be equipped with cleaning fixtures of different specifications to hold PCBA boards of different specifications. Moreover, the number of PCBA boards that can be placed in the cleaning fixture is small, which affects production efficiency. Even if some cleaning fixtures can hold PCBA boards of different specifications, it is still not convenient to take and place PCBA boards from the cleaning fixture, which affects the efficiency of loading and unloading.
[0004] Therefore, how to provide a tooling that can quickly pick up and place PCBA boards of different specifications has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention
[0005] In view of the above existing technical problems, the utility model provides an opening and closing net bag quick replacement tool, which can quickly replace the PCBA board by designing the opening and closing net bag to improve the versatility and convenience of the tool.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model comprises a main frame 1 and a row of net bags 2 which can be quickly hung in the main frame 1 .
[0035] like Figure 4As shown, a vertical hanging plate 11 is fixedly installed on the inner side surfaces of both sides of the main frame 1; a row of grooves 12 with equal spacing are provided on the rear side surface of the vertical hanging plate 11, and the grooves 12 are used to hang the corresponding net bags 2.
[0036] like Figure 2 , Figure 3 , Figure 5 As shown, the net bag 2 includes an L-shaped net 21, an opening and closing net 22, two side baffles 23, and two fastening buckles 25, which are specifically described as follows.
[0037] The two L-shaped sides of the L-shaped net 21 are respectively connected to the inner side surfaces of the two side baffles 23 .
[0038] The two ends of the bottom edge of the opening and closing net 22 are movably mounted on the two side baffles 23 through a rotating shaft, so that the opening and closing net 22 is located in front of the L-shaped net 21 and forms a U shape together with the L-shaped net 21. At the same time, the opening and closing net 22 can be turned forward and backward with the bottom edge as the axis.
[0039] In this way, the front side of the net bag 2 can be conveniently opened and closed. When replacing the PCBA board, the operator does not need to take down the entire net bag 2. He only needs to open the opening and closing net 22 on the front side of the net bag 2 to conveniently put the PCBA board into the net bag 2, thereby improving the work efficiency of loading and unloading.
[0040] like Figure 2 , Figure 3 As shown, a clamping buckle 25 is respectively provided on the top of the inner side surface of the two side baffles 23; the clamping buckle 25 is used to lock the opening and closing net 22, so that the structure of the net bag 2 is stable.
[0041] like Figure 6 As shown, the rear end of the clamping buckle 25 is fixedly mounted on the corresponding side baffle 23, and the front end thereof is a hook-shaped spring piece, which can automatically clamp the corresponding side edge of the opening and closing net 22, thereby clamping the corresponding side edge of the opening and closing net 22 between the inner side of the hook-shaped spring piece and the corresponding side baffle 23, ensuring that the PCBA board in the net bag 2 will not fall out of the opening and closing net 22.
[0042] In specific implementation, since the clamping buckle 25 is in the form of a spring sheet, the operator can open the opening and closing net 22 from the hook-shaped spring sheet of the clamping buckle 25 by hand. And when the operator closes the opening and closing net 22, the side of the opening and closing net 22 can be automatically clamped in the hook-shaped spring sheet corresponding to the clamping buckle 25, such as Figure 7 shown.
[0043] In other embodiments, Figure 6 , Figure 7As shown, the net bag 2 also includes an opening and closing clamping member 26. In order to prevent the locking function of the clamping buckle 25 from failing, the opening and closing clamping member 26 is used as a secondary clamping component to further lock the opening and closing net 22, so that the structure of the net bag 2 is more stable.
[0044] In a specific implementation, an opening and closing clamping member 26 is provided on the top of the inner side surface of one of the side baffles 23; the rear end of the opening and closing clamping member 26 is movably mounted on the corresponding side baffle 23 through a rotating shaft, so that the opening and closing clamping member 26 can rotate around the rotating shaft; the front end of the opening and closing clamping member 26 is hook-shaped, which is used to clamp one end of the top edge of the opening and closing net 22, such as Figure 7 shown.
[0045] In this way, when closing the opening and closing net 22, first use the two clamping buckles 25 to clamp the two side edges of the opening and closing net 22, and then rotate the hook-shaped front end of the opening and closing clamping member 26 downward with the rotation axis as the center, so as to clamp one end of the top edge of the opening and closing net 22, thereby strengthening the closing effect of the opening and closing net 22 and further ensuring that the PCBA board in the net bag 2 will not fall out of the opening and closing net 22. When opening the opening and closing net 22, it is only necessary to rotate the hook-shaped front end of the opening and closing clamping member 26 upward with the rotation axis as the center to release the locking function of the hook-shaped front end on the top edge of the opening and closing net 22, and then pull the two side edges of the opening and closing net 22 out of the hook-shaped spring pieces of the two clamping buckles 25 to release the locking function of the hook-shaped spring pieces on the side edges of the opening and closing net 22.
[0046] In other embodiments, Figure 4-Figure 7 As shown, a vertical hanging plate 11 is installed on the inner side surfaces of both sides of the main frame 1; a row of grooves 12 with equal spacing is provided on the rear side surface of the vertical hanging plate 11. Correspondingly, at least a pair of horizontal hanging columns 24 are symmetrically installed on the outer sides of the two side baffles 23 of the net bag 2, and the horizontal hanging columns 24 can be hung in the corresponding grooves 12.
[0047] During specific implementation, each net bag 2 is quickly hung in the corresponding groove 12 of the main frame 1 through the horizontal hanging columns 24 on both sides, so that the required net bags 2 can be hung in the main frame 1 in a row, and the net bags 2 of the required size can be quickly replaced, thereby facilitating the operator to quickly complete the assembly of the tooling and saving assembly time.
[0048] In other embodiments, Figure 1 , Figure 2As shown, the net bag 2 can be set to different lengths, widths and heights according to the different sizes of the PCBA board, so that net bags 2 of different sizes can be used to hold PCBA boards of different sizes. In this way, net bags 2 of different sizes can be hung in the same main frame 1, so that PCBA boards of different sizes can be cleaned at the same time. In addition, the net bag 2 is made of SUS304 material to ensure the durability of the tooling when cleaning the PCBA board.
[0049] When the utility model is working, firstly, different sizes of net bags 2 are designed according to different sizes of PCBA boards. Then, the net bags 2 of the required size are hung into the corresponding grooves 12 of the hanging plates 11 on both sides of the main frame 1 through the horizontal hanging columns 24 on both sides, so that each net bag 2 is installed in a row in the main frame 1. Secondly, the opening and closing net 22 on the front side of the net bag 2 is turned over, and the PCBA board is placed in the net bag 2. The large net bag 2 is loaded with a large PCBA board, and the small net bag 2 is loaded with a small PCBA board. Then, for each net bag 2, the side edges of the corresponding opening and closing net 22 are locked by the clamping buckle 25, and the top edge of the corresponding opening and closing net 22 is locked by the opening and closing clamping piece 26, so as to prevent the PCBA board from falling out of the net bag 2. Finally, the PCBA board is cleaned using this tooling.
[0050] When a batch of PCBA boards are cleaned, the operator does not need to remove the net bag 2 from the main frame 1, but only needs to open the clamping buckle 25 and the opening and closing clamping piece 26, and turn down the opening and closing net 22 on the front side of the net bag 2, so as to conveniently take out the PCBA boards from the net bag 2. After that, a new batch of PCBA boards is replaced and placed in the net bag 2 of the corresponding size, and then the opening and closing net 22 on the front side of each net bag 2 is locked by the clamping buckle 25 and the opening and closing clamping piece 26.
[0051] In summary, the utility model uses net bags 2 of different sizes to hold PCBA boards of different sizes, adapts to PCBA boards of different sizes, heights, and thicknesses, and achieves the purpose of cleaning PCBA boards of different sizes with one tool, thereby improving the versatility and convenience of the PCBA cleaning tool. In addition, the net bag 2 is an openable and closable type, and the PCBA board can be conveniently taken in and put out by manually disassembling the opening and closing net 22, which reduces the time of hanging the net bag 2 and improves the efficiency of loading and unloading.
