Description

Technical Field

[0001] The utility model relates to the technical field of circuit board welding, in particular to a welding correction tool for circuit board surface mounted components. Background Art

[0002] With the development of automatic technology, the automatic welding technology of circuit boards has become more and more mature. However, in many cases, such as trial manufacturing of new products, customized products and circuit board maintenance, automatic welding cannot replace manual welding.

[0003] The existing manual soldering method usually involves inserting electronic components into the corresponding mounting holes of the circuit board, and then placing the circuit board on a desktop for soldering. For components with a certain height and relatively thin pins, such as capacitors, when manually soldering, one needs to hold the solder with one hand and the soldering iron with the other hand. The capacitor also needs to be kept perpendicular to the circuit board. If the desktop shakes due to external factors during the soldering process and the component deviates from its original position, it is easy to cause solder leaks or unsightly solder joints if they are not corrected and fixed. Utility Model Content

[0004] The utility model aims to provide a circuit board surface mount component welding correction tool to solve the problem that the components deviate from their original positions due to the shaking of the desktop caused by external factors, which may easily cause welding leaks or unsightly solder joints if not corrected and fixed.

[0005] To achieve the above-mentioned purpose, a circuit board surface mount component welding correction tool is provided, including a base plate, support columns are fixedly connected to the four corners of the top of the base plate, a fixing frame is fixedly connected to the top of the support column, cross plates are installed on opposite sides of the fixing frame, a plurality of groups of threaded holes are formed throughout the cross plate, threaded rods are threadedly connected inside the threaded holes, and a conical rubber block for correction and fixation is fixedly connected to the bottom of the threaded rod.

[0006] As a further improvement of the technical solution, slide grooves are provided on opposite sides of the fixed frame, and sliders are slidably connected inside the slide grooves. A pair of sliders are fixedly connected to both sides of the cross plate.

[0007] As a further improvement of the technical solution, a plurality of groups of limit holes for adjusting the distance are opened on one side of the fixed frame, and the same limit holes are opened on the side of the slider close to the slide groove and the internal sliding connection is provided with a limit pin.

[0008] As a further improvement of the present technical solution, a through groove is opened in the middle of the base plate, a fixed block is fixedly connected to the middle of the through groove, and the first threaded column and the second threaded column are rotatably connected on both sides of the fixed block and the opposite sides of the through groove respectively, and the outer sides of the first threaded column and the second threaded column are threadedly connected with clamping blocks for fixing, and the first threaded column and the second threaded column are fixedly connected with a rotating block on one side outside the base plate.

[0009] As a further improvement of the technical solution, the thread directions of the first threaded column and the second threaded column are opposite.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The circuit board surface mounted component welding correction tool has the first threaded column and the second threaded column threads arranged oppositely, so that when the rotating blocks on both sides are rotated in the same direction, the two clamping blocks can move towards each other to clamp the circuit board, so that circuit boards of different sizes can be clamped and fixed, thereby improving the practicality of the device. The mounted component is placed in the welding position, and the threaded rod is rotated to move downward, so that the conical rubber block at the bottom thereof can correct and fix the component, so that even if the desktop shakes due to external factors, the component will not deviate from the original position, thereby improving the stability of the device. In addition, multiple groups of correction and fixing parts are arranged on the same horizontal plane, so that multiple components can be welded and fixed, and back and forth adjustment is avoided, thereby improving work efficiency. If multiple components at other levels are to be corrected and fixed, it is only necessary to release the limit of the limit pin, move the horizontal plate to the horizontal position, and then insert the limit pin. The correction and fixation of multiple components at different horizontal planes further improves the practicality of the device and also improves the efficiency of component welding.

The capacitor also needs to be kept perpendicular to the circuit board. If the desktop shakes due to external factors during the soldering process and the component deviates from its original position, it is easy to cause welding leakage or unsightly solder joints if it is not corrected and fixed. Before soldering, the circuit board is first placed between the two clamping blocks 16. Because the first threaded column 14 and the second threaded column 15 have opposite threads, rotating the rotating block 17 in the same direction at the same time can drive the first threaded column 14 and the second threaded column 15 to rotate. While rotating, the two clamping blocks 16 located on the outside move toward each other and clamp the circuit board, so that circuit boards of different sizes can be clamped and fixed. , improve the practicality of the device, at this time, put the mounted component into the welding position, and rotate the threaded rod 6 to move downward, first adjust the component to the welding position, so that the conical rubber block 7 at the bottom of the threaded rod 6 squeezes the component downward and fixes it, and then start welding. The multiple groups of threaded rods 6 on the horizontal plate 4 can correct and fix the components at multiple welding positions on the same horizontal level on the circuit board.

Correction and fixation of multiple components on different horizontal planes further improves the practicality of the device and also improves the efficiency of component welding.

[0021] Working principle: Before welding, put the circuit board between the two clamping blocks 16. Since the first threaded column 14 and the second threaded column 15 have opposite threads, rotating the rotating block 17 in the same direction at the same time can drive the first threaded column 14 and the second threaded column 15 to rotate. At the same time, the two clamping blocks 16 located on the outside thereof move toward each other and clamp the circuit board, which can clamp and fix circuit boards of different sizes and improve the practicality of the device. At this time, put the mounting component into the welding position, and rotate the threaded rod 6 downward. First, adjust the component to the welding position so that the conical rubber block 7 at the bottom of the threaded rod 6 is aligned with the welding position. After the components are squeezed downward and fixed, welding begins. Even if external factors cause the desktop to shake, the components will not deviate from their original positions, thereby improving the stability of the device. The multiple sets of threaded rods 6 on the horizontal plate 4 can correct and fix components at multiple welding positions on the same horizontal level on the circuit board. If multiple components at other levels are to be corrected and fixed, first release the limit pins 11 inside the limit holes 10 of the slide grooves 8 and the sliders 9, then move the horizontal plate 4 to another welding horizontal position, and insert the limit pins 11. Correction and fixation of multiple components on different horizontal planes further improves the practicability of the device and also improves the efficiency of component welding.
