[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] This embodiment discloses a circuit board soldering fixture, the overall structure of which is as follows: Figure 1 As shown, the main structural components include: base 1, support arm 2, bearing plate 3, pressing mechanism 4, and stop mechanism 5.

[0036] Among them, the base 1 serves as the bottom structural support, and the four corners of the base 1 are equipped with support legs 9, which support the base 1.

[0037] Support arms 2 are symmetrically arranged at the left and right ends of the plate surface of the base 1. The support arms 2 are vertically supported and are perpendicular to the plate of the base 1.

[0038] The support plate 3 is hinged to two sets of vertically distributed support arms 2, and the support plate 3 provides a support platform for the placement of the circuit board.

[0039] Based on the support plate 3, a pressing mechanism 4 is installed at the rear side of the support plate 3, and a stop mechanism 5 is installed at the other three sides of the support plate 3.

[0040] The clamping mechanism 4 is used to clamp and fix the circuit board. Typically, the circuit board is placed on the support plate 3 along the direction close to the clamping mechanism 4 so that the edge position of the circuit board is clamped and fixed by the clamping mechanism 4.

[0041] The structure of the clamping mechanism 4 is as follows: Figure 2 As shown, it includes a fixing block 41, a threaded seat 42, and a clamping screw 44;

[0042] The fixing block 41 is a long strip-shaped block structure used to fix it to the bearing plate 3 so as to realize the installation of the entire press mechanism 4 at the rear side of the bearing plate 3.

[0043] Based on the structure of the fixing block 41, a threaded seat 42 is provided for support and is fixed to the top of the fixing block 41. The threaded seat 42 has a threaded hole adapted to the clamping screw 44, so that the clamping screw 44 is assembled in the threaded hole of the threaded seat 42 through the threaded structure.

[0044] Meanwhile, a turning handle 43 is provided at the top of the clamping screw 44 so that the operator can rotate the clamping screw 44 to realize the up and down movement of the clamping screw 44.

[0045] A clamping head 45 is assembled at the bottom end of the clamping screw 44. The clamping head 45 can be made of rubber or silicone. It uses the flexible clamping action of the clamping head to clamp and fix the circuit board, thereby effectively reducing wear and damage to the circuit board and achieving better protection for the circuit board. In addition, the overall structure is disc-shaped to increase the contact area between the clamping head 45 and the circuit board, thereby improving the clamping and fixing effect of the clamping head 45.

[0046] Preferably, considering the different sizes of the circuit boards, multiple clamping mechanisms 4 are distributed at intervals along the rear side of the support plate 3, and the clamping mechanism 4 is selected according to the specific situation of the circuit board.

[0047] Furthermore, the stop mechanism 5 plays a limiting and protective role around the bearing plate 3, and the stop mechanism 5 includes a slidable movable baffle 53. When used with circuit boards of different sizes, the movable baffle 53 is slidably adjusted and limited and fixed in the opposite direction of the fixing block 41 of the pressing mechanism 4.

[0048] The structure of the gear shift mechanism 5 is as follows: Figure 3 As shown, it includes guide baffles 51 symmetrically distributed on the left and right sides of the bearing plate 3, and movable baffles 53 that can slide along the guide baffles 51.

[0049] An elongated adjustment groove 52 is provided on the guide baffle 51. A slidable movable baffle 53 is installed between the two sets of guide baffles 51 through the adjustment grooves 52 of the two sets of guide baffles 51.

[0050] like Figure 4 As shown, a connecting shaft 55 is fixed to one end of the movable baffle 53. After the connecting shaft 55 passes through the adjustment groove 52 of one of the guide baffles 51, an anti-detachment baffle 56 is fixedly connected. The diameter of the anti-detachment baffle 56 is greater than the height of the hole in the adjustment groove 52, so that the end of the movable baffle 53 where the connecting shaft 55 is located will not detach from the guide baffle 51.

[0051] The other end of the movable baffle 53 is fixedly connected to a baffle screw 57. After the baffle screw 57 passes through the adjustment groove 52 of another guide baffle 51, it is locked with a plum nut button 54 by a thread.

[0052] Torx nut button 54 Figure 7 As shown, a threaded hole for matching the baffle screw 57 is provided in the center of the device. By utilizing the matching effect between the threaded hole and the baffle screw 57, the plum blossom nut button 54 can be installed on the baffle screw 57.

[0053] When the Torx nut 54 is loosened, the movable baffle 53 is in a sliding state. Depending on the specific situation of the circuit board being placed, when the movable baffle 53 contacts and abuts the circuit board, it stops sliding and the Torx nut 54 is tightened to position the movable baffle 53 in the current state.

[0054] Therefore, for the circuit board soldering fixture disclosed in this embodiment, when clamping the circuit board, one side of the circuit board is aligned with any one of the guide baffles 51, and another side of the circuit board is aligned with the fixing block 41 of the clamping mechanism 4, so as to place the circuit board on the support plate 3; the handle 43 is rotated to screw in the clamping screw 44, and the clamping head 45 moves down and clamps the circuit board. The clamping mechanism 4 is selected according to the specific size of the circuit board. At the same time, the sliding baffle 53 is slid so that the sliding baffle 53 contacts and pushes against the circuit board, and then the Phillips head nut 54 is tightened to position the sliding baffle 53 in the current state, thereby completing the clamping and fixing installation of the circuit board on the fixture of this embodiment.

[0055] After the welding operation is completed, turn the handle 43 to unscrew the clamping screw 44, so that the clamping head 45 can release its clamping and fixing effect on the circuit board. Then, loosen the Phillips head nut 54 and push open the movable baffle 53 to remove the circuit board.

[0056] The circuit board welding fixture disclosed in this embodiment supports the circuit board with a carrier plate 3 and is clamped and fixed by a clamping mechanism. This achieves good support and fixation of the circuit board. At the same time, the flexible clamping action of the clamping head of the clamping mechanism can effectively protect the circuit board and reduce wear and damage. Meanwhile, the side stop mechanism 5 can lower and protect the circuit board, greatly reducing the possibility of the circuit board detaching from the carrier plate 3 and ensuring the smooth progress of the welding operation.

[0057] Furthermore, multiple clamping mechanisms are spaced apart, and the movable baffle of the stop mechanism 5 can be slidably adjusted, so that the circuit board welding fixture of this embodiment can also be adapted to the clamping and fixing of circuit boards of different sizes, thereby improving the versatility of the fixture of this embodiment.

[0058] Example 2

[0059] This embodiment discloses a circuit board welding fixture. Based on the structure disclosed in Embodiment 1, the support plate 3 is further configured to be rotatable and adjustable to improve the flexibility of the fixture and make it easier for operators to perform welding operations.

[0060] First, such as Figure 2 and Figure 6 As shown, hinge ears 7 are symmetrically arranged at the lower left and right sides of the bearing plate 3, and are hinged to the top part of the support arm 2.

[0061] Secondly, the specific hinged connection structure is designed as follows: Figure 6 As shown, a gear plate seat 71 is provided on the hinge lug 7, and a copper nut 72 is fixed at the center of the gear plate seat 71; for example... Figure 5 As shown, the support arm 2 is provided with a toothed disc 6 that engages with the toothed disc seat 71, and a through hole is provided at the center of the toothed disc 6.

[0062] For example Figure 1 As shown, a Torx screw 8 is fitted between the hinge lug 7 and the support arm 2, and the Torx screw 8 is positioned as follows: Figure 8 As shown, it includes a screw section and a toggle head section. After the gear plate 6 and gear plate seat 71 are matched and assembled, the screw section of the toggle head screw 8 passes through the through hole of the gear plate 6 and is locked to the copper nut 72.

[0063] Therefore, when it is necessary to adjust the rotation angle of the bearing plate 3, loosen the toggle screw 8, rotate the bearing plate 3, adjust it to the required angle, and then tighten the toggle screw 8. Under the action of the meshing toothed structure of the toothed disc 6 and the toothed disc 72, the bearing plate 3 can be tightly locked at the current angle.

[0064] Preferably, to reduce rotational wear, a washer is fitted onto the screw portion of the toggle screw 8, with the washer located between the toggle head of the toggle screw 8 and the support arm 2.

[0065] In summary, for the circuit board welding fixture disclosed in this embodiment, the support plate 3 for placing the circuit board has a rotatable and adjustable structure. By adjusting the usage angle of the support plate 3, a better welding operation angle can be provided for the operator, thereby improving the ease of use of this fixture.

[0066] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
