Description

Technical Field

[0001] This utility model relates to the field of electronic component welding technology, specifically to a welding auxiliary tool for MOSFETs and inverter boards. Background Technology

[0002] In the manufacturing process of electronic devices, inverter boards typically need to be precisely soldered to MOSFETs to ensure the stability and reliability of the circuit.

[0003] However, because the insertion direction of the pins of the MOSFET on the inverter board is different from the soldering direction, and the top area of ​​the MOSFET is small, it is difficult to achieve precise positioning of the MOSFET on the inverter board during the soldering process. This can easily lead to soldering position deviation, affecting soldering quality and circuit performance. In addition, only one MOSFET can be soldered at a time, resulting in low soldering efficiency.

[0004] The present invention aims to provide a welding auxiliary tool for MOSFETs and inverter boards. By optimizing the structural design, it solves the problems of difficult welding positioning, poor stability, complicated operation and heat dissipation in the prior art. Utility Model Content

[0005] The purpose of this invention is to provide a welding auxiliary tool for MOSFETs and inverter boards. This welding auxiliary tool can accurately position multiple MOSFETs on the inverter board simultaneously, thereby avoiding displacement of the welding position during the welding process, ensuring welding quality and circuit performance, and can weld multiple MOSFETs at once, improving welding efficiency.

[0006] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: a welding auxiliary tool for MOSFET and inverter board, including a fixing base;

[0007] A detachable structure is provided on the fixed base, which enables a detachable connection between the inverter board and the fixed base;

[0011] In some embodiments, the fixing base further includes four waist-shaped holes, which are symmetrically arranged at both ends of the groove block and along the height direction of the groove block;

[0012] A fastening screw, one end of which passes through the oblong hole and is screwed into the fixing block.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] refer to Figure 1-2 A welding auxiliary tool for MOSFETs and inverter boards includes a mounting base 1, a detachable structure 2, and multiple placement slots 3. The mounting base 1 is a basic support structure that can support other structures. The mounting base 1 can be made of aluminum alloy. The detachable structure 2 is located on the mounting base 1, enabling a detachable connection between the inverter board and the mounting base 1. The multiple placement slots 3 are symmetrically located at both ends of the mounting base 1. MOSFETs are placed in the placement slots 3, allowing the pins of the MOSFETs to pass through the inverter board. The bottom wall of the placement slot 3 supports the MOSFETs. The pins of the MOSFETs are inserted into the inverter board, which can constrain the MOSFETs in the horizontal and vertical directions. This allows for the simultaneous and precise positioning of multiple MOSFETs on the inverter board, avoiding displacement of the welding position during the welding process, ensuring welding quality and circuit performance, and enabling the welding of multiple MOSFETs at once, thus improving welding efficiency.

[0026] In some embodiments, the mounting base 1 includes a mounting block 11 and a slotted block 12. The mounting block 11 provides basic support to ensure that the welding auxiliary tool is placed horizontally. The slotted block 12 covers the top of the mounting block 11. Multiple placement slots 3 are symmetrically provided at both ends of the slotted block 12. The position of the placement slot 3 on the slotted block 12 can be set according to the welding position of the MOSFET on the inverter board. The size of the placement slot 3 can be set according to the size of the MOSFET. A certain gap can be left between the MOSFET and the placement slot 3 to ensure the stability of the MOSFET placed in the placement slot 3 while facilitating the placement of the MOSFET.

[0027] In some embodiments, to facilitate the placement of the MOSFET in the placement slot 3, the mounting base 1 further includes four oblong holes 13 and fastening screws 14. The four oblong holes 13 are symmetrically arranged at both ends of the slot block 12 and along the height direction of the slot block 12, providing vertical adjustment space to adjust the distance between the placement slot 3 and the inverter board, facilitating the insertion of the MOSFET into the inverter board while simultaneously placing it in the placement slot 3. One end of the fastening screw 14 passes through the oblong hole 13 and is screwed into the mounting block 11. By tightening the fastening screw 14, the slot block 12 and the mounting block 11 can be tightly connected, realizing the adjustment of the height of the slot block 12 on the mounting block 11.

[0028] In some embodiments, to facilitate the removal of the fixing base 1 and reduce the labor intensity during welding, the fixing base 1 also includes a through groove 15, which extends laterally through the fixing block 11, thereby reducing the overall weight of the welding auxiliary tool and facilitating the operator's use of the welding auxiliary tool.

[0029] In some embodiments, to facilitate the installation or removal of components such as the inverter board on the mounting base 1, the detachable structure 2 includes four fixing posts 21 and a locking rod 22. The four fixing posts 21 are arranged in an array on the top surface of the fixing block 11 and pass through the slotted block 12. The fixing posts 21 are embedded with threaded holes. The locking rod 22 passes through the inverter board and is screwed into the fixing posts 21. When it is necessary to install the inverter board on the mounting base 1, the inverter board is placed above the fixing posts 21, the mounting holes on the inverter board are aligned with the fixing posts 21, and then the locking rod 22 is passed through the mounting holes and screwed into the fixing posts 21 to achieve a stable installation of the inverter board. When disassembling, simply twist the locking rod 22 in the opposite direction to unscrew it from the fixing posts 21 to easily remove the component.

[0030] In some embodiments, the detachable structure 2 further includes a rotating rod 23, which is coaxially disposed on the top of the locking rod 22. The operator can apply torque through the rotating rod 23 to tighten or loosen the locking rod 22 more easily.

[0031] In some embodiments, the cross-section of the rotating rod 23 can be a regular hexagon, which can increase the contact area between the rotating rod 23 and the hand, making it easier to rotate. At the same time, when the rotating rod 23 is tightened, tools such as wrenches can be used for operation.

[0032] In some embodiments, the bottom wall of the placement groove 3 is provided with a rubber pad. The rubber pad can buffer the impact force between the MOS tube and the bottom wall of the placement groove 3 and increase the friction between the two, preventing the MOS tube from sliding in the placement groove 3 and further improving its stability.

[0033] The specific working principle is as follows:

[0034] During the welding process, the position of the fastening screw 14 in the waist-shaped hole 13 is adjusted according to the set distance, thereby adjusting the height of the fixing column 21 extending out of the surface of the slot block 12, and thus adjusting the height between the placement slot 3 and the inverter board.

[0035] Place the inverter board on the four fixing posts 21, align the mounting holes on the inverter board with the fixing posts 21, pass the locking rod 22 through the mounting holes, and rotate the rotating rod 23 to screw the locking rod 22 onto the fixing posts 21, thus achieving a stable installation of the inverter board.

[0036] Multiple MOSFETs are sequentially placed in multiple placement slots 3 at one end of the slot block 12. The MOSFETs are attached to one end face of the slot block 12 and moved along the height direction so that the pins of the MOSFETs pass through the corresponding soldering positions on the inverter board. When moving to the placement slot 3, due to the certain gap between the pins of the MOSFETs and the corresponding soldering holes on the inverter board, the MOSFETs can rotate slightly and thus be placed in the placement slot 3. Through the combined action of the placement slot 3 and the inverter board, multiple MOSFETs are simultaneously and accurately positioned on the inverter board. Soldering tools are used to solder multiple MOSFETs to the inverter.

[0037] Rotate the welding aid so that one end of the slot block 12 without the MOSFET is facing the operator, and follow the steps above to weld the MOSFET to the inverter at the other end.

[0038] By rotating rod 23 to loosen locking rod 22, locking rod 22 is separated from fixed post 21, and inverter board is removed from fixed seat 1, thus completing the entire welding process.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
