[0026] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0027] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description.

[0030] In one embodiment, see Figures 1 to 4 The utility model provides a PCB welding tool, comprising:

[0031] A platform 1, a rotating shaft 2 provided on the platform 1, wherein the platform 1 is connected to one end of a bottom plate 3 via the rotating shaft 2, so that the bottom plate 3 can be tilted and flipped relative to the platform 1;

[0032] The clamping assembly includes a mounting seat 4, a clamping plate 5, a spring assembly 6, and a handle 7. The mounting seat 4 is fixedly mounted on the base plate 3. The mounting seat 4 includes a first mounting seat 41 and a second mounting seat 42. The clamping plate 5 includes a first clamping plate 51 and a second clamping plate 52. The first mounting seat 41 is movably connected to the first clamping plate 51. The handle 7 is stretched in a direction away from the first mounting seat 41 to compress the spring assembly 6 and drive the second clamping plate 52 away from the first clamping plate 51 to facilitate the installation of the PCB board 9. After the PCB board 9 is installed, the handle 7 is released, and the spring assembly 6 rebounds and pushes the second clamping plate 52 and the first clamping plate 51 to clamp the PCB board 9.

[0033] The rotating assembly includes a rotating pin structure 8 and a positioning block 10. The rotating pin structure 8 cooperates with the second mounting seat 42 through the positioning block 10 to achieve limited rotation. The positioning block 10 is driven by the rotating handle 7 to rotate relative to the second mounting seat 42 and drive the splint 5 and then drive the PCB board 9 to rotate.

[0034] The utility model can adjust the welding angle by arranging the tool body on a bottom plate that can be tilted and flipped relative to the platform; at the same time, the PCB board is clamped by the clamping plate to achieve fixation and convenient welding; and a rotating component is provided to drive the clamping plate to rotate with a handle, so that multi-directional welding can be achieved without disassembly.

[0035] In one embodiment, the PCB board 9 is clamped to the clamping plate from the side. Compared with clamping the PCB board 9 from the front, clamping from the side can better avoid components on the PCB.

[0036] In one embodiment, if Figure 2 As shown, the double arrow indicates the rotation direction of the shaft 2. The shaft 2 and the first mounting seat 41 are located on one side. The motor drives the shaft 2 to lift the base plate 3 so that it is tilted relative to the platform 1. The motor drive can save labor and accurately control the tilt angle of the base plate 3 and the platform 1.

[0037] In one embodiment, if Figure 3 As shown in Figure 3 The double arrows in the middle indicate the extension and retraction directions of the clamping assembly, which includes the handle 7, the second clamping plate 52, and the spring assembly 6. By pulling the handle 7 away from the first mounting seat 41, the spring assembly 6 is compressed and the second clamping plate 52 is moved away from the first clamping plate 51 to facilitate installation of the PCB 9. After the PCB 9 is installed, the handle 7 is released, and the spring assembly 6 rebounds and pushes the second clamping plate 52 against the first clamping plate 51, clamping the PCB 9.

[0038] In one embodiment, the PCB welding fixture further includes a guide rail 11, one end of which is fixedly connected to the second clamping plate 52, and the other end is fixedly connected to the positioning block 10, for limiting the movement direction of the spring assembly 6. In a specific embodiment, as Figure 3 As shown, the double arrows in the figure indicate the extension and contraction directions of the handle 7, spring assembly 6, guide rail 11, and second clamping plate 52. The guide rail 11 is a retractable guide sleeve or guide tube. The spring assembly 6 moves in the direction of the guide rail 11, and is restricted in other directions. When the spring assembly 6 is compressed, the guide rail 11 contracts, causing the second clamping plate 52 to move toward the positioning block 10 and away from the first clamping plate 51, thereby creating space for installing or replacing the PCB board 9. When the spring assembly 6 rebounds, the guide rail 11 extends, causing the second clamping plate 52 to move away from the positioning block 10 and toward the first clamping plate 51, clamping the PCB board and securing it. When the positioning block 10 rotates, the guide rail 11 will drive the second clamping plate 52 to rotate. At this time, because the first clamping plate 51, PCB board 9, and second clamping plate 52 are in a clamped state, the first clamping plate 51 and PCB board 9 are driven by the second clamping plate 52 to rotate synchronously, thereby adjusting the welding angle of the PCB board and facilitating multi-directional welding. It should be noted that the free length of the spring assembly 6 should be greater than or equal to the length between the second clamping plate 52 and the positioning block 10 when the PCB board 9 is clamped, so as to ensure the clamping effect of the PCB board 9.

[0039] As a preferred embodiment, the spring assembly 6 can increase the wire diameter, improve the coil density or use high elasticity materials to increase the elastic effect, and can also ensure the clamping effect of the PCB board 9 by using a spring combination.

[0040] In another specific embodiment, the guide rail 11 can be a connecting shaft passing through the positioning block 9 and the second mounting seat 42. The guide rail 11 passes through the spring assembly, one end is fixedly connected to the second splint 52, and the other end is fixedly connected to the handle 7. When the handle 7 is subjected to tension, part of the guide rail 11 extends outward, driving the second splint 52 to move away from the first splint 51, and the spring assembly 6 is compressed. When the handle 7 is released or pushed inward, part of the guide rail 11 is pushed inward, driving the second splint 52 to move toward the first splint 51, and the spring assembly 6 rebounds. To facilitate installation, the guide rail 11 is provided with two corresponding protrusions at the end points of the travel of the spring assembly 6, which are used to realize snap-fitting with the grooves provided on the surface of the positioning block 10 facing the second clamping plate 52 and the surface of the second mounting seat 42 facing the handle 7 at the compression end point and the rebound end point of the spring assembly 6, respectively. That is, when the handle 7 is stretched outward to a certain length sufficient to install the PCB board 9, the guide rail 11 can be snapped into the positioning block 9 to achieve fixation; when the handle 7 is pushed inward to a certain length sufficient to clamp the PCB board, the guide rail 11 can be snapped into the second mounting seat 42 to achieve fixation.

[0041] In one embodiment, to facilitate installation, Figure 2 As shown in FIG, the bottom plate 3 is lifted to a certain angle by the rotating shaft 2 and then fixed, for example, the angle between the bottom plate 3 and the platform 2 is 60 degrees. Figure 3 As shown in FIG, the handle 7 is pulled away from the mounting base 4, compressing the spring assembly 6 and moving the second clamping plate 52 away from the first clamping plate 51. A certain space is exposed between the clamping plates 5 to facilitate the side installation of the PCB board 9. At this time, the tool body is tilted, and the PCB board 9 is not likely to slip. After the PCB board 9 is installed, the handle 7 is released or pushed toward the mounting base 4. The spring assembly 6 rebounds and pushes the second clamping plate 52 toward the first clamping plate 51, finally clamping the PCB board 9, completing the installation and clamping of the PCB board 9.

[0042] In one embodiment, the handle 7 can drive the positioning block 10, the second clamping plate 52 and then drive the first clamping plate 51 and the PCB board 9 to rotate. The rotation can be synchronous rotation. The positioning block 9 is provided with an angle mark so that the position of the PCB board rotation angle can be determined by the positioning block 9. Figure 4 As shown, the double arrows in the figure represent the rotation direction of the handle 7, the positioning block 10, the second clamping plate 52, the first clamping plate 51, and the PCB board 9, that is, they can rotate both inward and outward.

[0043] In one embodiment, the rotating pin structure 8 includes a plurality of positioning pin holes and elastic positioning pins matching the positioning pin holes.

[0044] In a specific embodiment, a plurality of positioning pin holes are arranged around the surface of the second mounting seat 42 facing the first mounting seat 41, and an elastic positioning pin is protruding from the surface of the positioning block 10 facing the second mounting seat 42. The elastic positioning pin is compressed by rotating the handle 7 until the elastic positioning pin is inserted into the positioning pin hole to achieve fixation.

[0045] In another specific embodiment, a plurality of positioning pin holes are protruding from the surface of the positioning block 10 facing the second mounting seat 42, and an elastic positioning pin is protruding from the surface of the second mounting seat 42 facing the first mounting seat 41. The elastic positioning pin is compressed by rotating the handle 7 until the elastic positioning pin is inserted into the positioning pin hole to achieve fixation.

[0046] In one embodiment, the rotating pin structure 8 includes a plurality of grooves and a ball screw matching the grooves.

[0047] In a specific embodiment, a radial groove is provided on the surface of the positioning block 10 facing the second mounting seat 42, and a ball screw is provided on the surface of the second mounting seat 42 facing the first mounting seat 41. The ball screw is compressed by rotating the handle 7 until the ball screw is stuck in the groove to achieve fixation.

[0048] In one embodiment, the rotating pin structure 8 includes a plurality of positioning pin holes and elastic positioning pins matching the positioning pin holes.

[0049] In a specific embodiment, a radial groove is provided on the surface of the second mounting seat 42 facing the first mounting seat 41, and a ball screw is provided on the surface of the positioning block 10 facing the second mounting seat 42. The ball screw is compressed by rotating the handle 7 until the ball screw is stuck in the groove to achieve fixation.

[0051] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them.
