[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0029] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Please see Figures 1-4 As shown in the figure, the instrument circuit board auxiliary welding mechanism provided in this embodiment of the utility model includes a base 1, and fixed columns 2 are fixedly connected to both sides of the top of the base 1. An adjustment component 3 is provided inside the fixed column 2.

[0031] The adjusting component 3 is rotatably mounted on one side with a fixed frame 4. Both sides of the inner wall of the fixed frame 4 are fixedly connected with support plates 5. Pressure plates 6 are slidably mounted on both sides of the fixed frame 4 above the support plates 5.

[0032] The circuit board is placed in the fixing frame 4. The bottom sides of the circuit board are supported by the support plates 5 on both sides of the inner wall of the fixing frame 4. The top of the circuit board is pressed and limited by a pair of pressure plates 6 above the support plates 5, thereby fixing the circuit board in the fixing frame 4. The fixing frame 4 is rotatably set on the fixing columns 2 on both sides of the top of the base 1. The angle of the fixing frame 4 can be freely adjusted by the adjustment component 3, so that the circuit board can be flipped and soldered.

[0033] Preferably, the adjusting component 3 includes a positioning cylinder 31 fixedly disposed on one side of the fixed column 2. A rotating rod 32 is rotatably connected to the inner wall of the positioning cylinder 31. A first gear 33 is fixedly connected to one end of the rotating rod 32. A second gear 34 is meshed with the outer side of the first gear 33. A fixing rod 35 is fixedly connected to the axis of the second gear 34. One end of the fixing rod 35 is fixedly connected to one side of the fixed frame 4. A positioning bolt 36 is screwed to the top of the positioning cylinder 31. The bottom end of the positioning bolt 36 abuts against the outer side of the rotating rod 32.

[0034] The rotating rod 32 rotates inside the positioning cylinder 31, causing the first gear 33 to drive the second gear 34 to rotate. The second gear 34 drives the fixing frame 4 to rotate through the fixing rod 35. This not only allows the fixing frame 4 to be flipped, but also allows the angle of the fixing frame 4 to be freely adjusted, which facilitates the soldering operation of the circuit board. After the circuit board is flipped or the angle is adjusted, the bottom end of the positioning bolt 36 is tightened to abut against the outside of the rotating rod 32, thereby positioning the rotating rod 32 and fixing the position of the fixing frame 4.

[0035] Preferably, a fixing seat 7 is fixedly connected to both sides of the top of the fixing column 2, and a movable plate 8 is slidably connected to the inner wall of the fixing seat 7. One side of the movable plate 8 is fixedly connected to one side of the pressure plate 6.

[0036] A pull rod 9 is fixedly connected to the top of the movable plate 8, and a spring 10 is sleeved on the pull rod 9.

[0037] Before installing the circuit board, pull the lever 9 to move the movable plate 8 within the fixed base 7, causing the movable plate 8 to move the pressure plate 6 upward and compress the spring 10, thus placing the circuit board between the support plate 5 and the pressure plate 6. Then, release the lever 9, allowing the movable plate 8 to move the pressure plate 6 downward under the elastic force of the spring 10, pressing down on the top of the circuit board.

[0038] Preferably, a pull plate 11 is fixedly connected to the top of the pull rod 9, and a knob 12 is fixedly connected to one end of the rotating rod 32.

[0039] The pull plate 11 allows for easy pulling of the pull rod 9, and the knob 12 allows for easy rotation of the rotating rod 32.

[0040] Preferably, a baffle 13 is fixedly connected to the top of the base 1, a chip removal groove 14 is opened on the top of the base 1, and a collection cabinet 15 is slidably connected to the inner wall of the base 1.

[0041] The baffle 13 can block the welding slag that falls on the top of the base 1 during welding, making it easy to clean the welding slag into the chip discharge trough 14, and collect the welding slag through the collection cabinet 15.

[0042] The working principle of this utility model is as follows: The circuit board is placed in the fixing frame 4. The bottom sides of the circuit board are supported by the support plates 5 on both sides of the inner wall of the fixing frame 4. The top of the circuit board is pressed and limited by a pair of pressure plates 6 above the support plates 5, thereby fixing the circuit board in the fixing frame 4. The fixing frame 4 is rotatably set on the fixing columns 2 on both sides of the top of the base 1. The rotating rod 32 rotates in the positioning cylinder 31, causing the first gear 33 to drive the second gear 34 to rotate. The second gear 34 drives the fixing frame 4 to rotate through the fixing rod 35. This not only allows the fixing frame 4 to be flipped, but also allows the angle of the fixing frame 4 to be freely adjusted, which is convenient for the soldering operation of the circuit board. After the circuit board is flipped or the angle is adjusted, the bottom end of the fixing bolt 36 is tightened to abut against the outside of the rotating rod 32, thereby positioning the rotating rod 32 and fixing the position of the fixing frame 4.

[0043] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
