Description

Technical Field

[0001] This utility model belongs to the field of soldering auxiliary tooling technology, specifically relating to a high-stability precision circuit board auxiliary operation multi-functional platform for small soldering furnaces. Background Technology

[0002] The core purpose of soldering precision circuit boards is to achieve reliable and durable electrical interconnection and mechanical fixation. There is a physical gap between the metal leads or solder terminals of electronic components and the copper pads on the circuit board. After the solder melts upon heating, its excellent wettability allows it to flow and cover both surfaces, filling the micron-sized gaps. Upon cooling and solidification, it forms a strong metallurgical bond layer, essentially constructing a miniature conductive bridge. This process ensures an extremely low-resistance, highly stable current path between the components and the circuit, which is fundamental to the circuit's functionality. Simultaneously, the mechanical strength generated by the solidified solder anchors the components in their predetermined positions, effectively resisting external forces such as vibration and impact, maintaining the structural integrity and long-term reliability of the precision circuit. Compared to other connection methods such as conductive adhesives and crimping, soldering offers significant advantages in conductivity, connection strength, process maturity, and cost-effectiveness, making it an indispensable and irreplaceable key process for meeting the demands of modern high-density, miniaturized, and high-performance electronic assembly.

[0003] In small-scale circuit board assembly and repair processes, soldering is required on the circuit boards. Operators often use small solder pots to melt solder and then place the circuit board on the surface of the solder for soldering. Since soldering only needs to be done on one side of the circuit board, special attention must be paid to the depth of the circuit board into the solder to prevent the solder from flowing to the other side of the circuit board. In general, during the soldering process, operators mostly use clamps to hold the circuit board for soldering. The operator's hand movements can affect the stability of the clamps and the circuit board, resulting in inadequate contact between the circuit board and the solder and failing to meet the soldering requirements of the circuit board. Therefore, it is necessary to design a tooling device that can be used with a small solder pot and meets the operator's requirements for circuit board soldering. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1 - Figure 5 As shown, a multi-functional platform for high-stability precision circuit board-assisted operation of a small soldering furnace includes:

[0028] A lifting support frame, on which a mounting column 3 is fixedly connected;

[0029] A lifting frame is connected to the mounting column 3, and a rotating bracket 10 is rotatably connected to the lifting frame;

[0030] The operating frame, connected to the rotating bracket 10, includes a first mounting rod 11 fixedly connected to the rotating bracket 10, a second mounting rod 12 slidably inserted into the first mounting rod 11, and a mounting plate 13 slidably connected to the second mounting rod 12. Both the first mounting rod 11 and the mounting plate 13 are threaded with bolts that can abut against the first mounting rod 11. After the user adjusts the positions of the second mounting rod 12 and the mounting plate 13, the bolts can be rotated to abut against the first mounting rod 11. The friction between the bolts and the first mounting rod 11 restricts the sliding of the second mounting rod 12 and the mounting plate 13. A clamping piece 14 is connected to the lower outer wall of the mounting plate 13, and multiple protrusions 15 are fixedly connected to the lower inner wall of the clamping piece 14.

[0031] As can be seen from the above, by setting up a multi-functional platform consisting of a lifting bracket, a lifting frame, and an operating frame, when using a small solder pot to solder the surface of a circuit board, the user can clamp the circuit board between two clamping plates 14 using the protrusion 15. By adjusting the position of the second mounting rod 12, the clamping plates 14 and the circuit board can be aligned with the molten solder. By adjusting the position of the mounting plate 13, the clamping plates 14 can clamp circuit boards of different sizes. The user can precisely control the depth to which the circuit board on the clamping plate 14 is immersed in the molten solder using the lifting bracket and the lifting frame, thereby precisely controlling the soldering accuracy of the molten solder on the surface of the circuit board.

[0032] Please see Figure 1 and Figure 3 As shown, the mounting plate 13 has multiple mounting holes at its lower end, and the clamping piece 14 is fixedly connected to the mounting plate 13 by bolts and mounting holes. Users can adjust the effective length of the clamping piece 14 by adjusting the connection position of the bolts and mounting holes.

[0033] The clip 14 is made of stainless steel to prevent molten solder from adhering to the surface of the clip 14.

[0034] Please see Figure 1 As shown, the surfaces of the first mounting rod 11 and the second mounting rod 12 are engraved with scale grooves, which facilitates the operator to determine the working position of the second mounting rod 12 and the mounting plate 13 according to the scale grooves.

[0035] The lifting frame includes a mounting frame 4 slidably connected to the mounting column 3, a positioning block 5 fixedly mounted on the mounting column 3, and a limiting rod 6 fixedly mounted on the mounting frame 4. The limiting rod 6 is slidably inserted into the positioning block 5. A spring 7 is connected between the mounting frame 4 and the positioning block 5. A pressure rod 8 is hinged to the positioning block 5. A connecting rod 9 is hinged between the pressure rod 8 and the mounting frame 4. The rotating bracket 10 is rotatably connected to the mounting frame 4.

[0036] As can be seen from the above, when the user needs to move the circuit board between the clamping pieces 14 downwards to contact the molten solder, the user can press down the pressure rod 8. The pressure rod 8 rotates around the positioning block 5 as a fulcrum. The rotating pressure rod 8 drives the connecting rod 9 to rotate, which in turn drives the mounting frame 4 to move downwards. The downward-moving mounting frame 4 will stretch the spring 7. Due to the limitation of the movement direction of the mounting frame 4 by the limiting rod 6, the mounting frame 4 can only move downwards on the mounting post 3. When the user releases the pressure rod 8, the stretched spring 7 returns to its original position, causing the mounting frame 4 below to slide upwards and return to its original position. The user can control the downward movement distance of the mounting frame 4 by the rotation angle of the pressure rod 8, thereby controlling the depth of the circuit board between the clamping pieces 14 into the molten solder.

[0037] Please see Figure 1 and Figure 3 As shown, the lifting bracket includes a base 1 and a hydraulic lifting column 2 fixedly installed on the base 1. The mounting column 3 is fixedly connected to the lifting end of the hydraulic lifting column 2. The hydraulic lifting column 2 can adjust the height of the mounting column 3 by extending and retracting, thereby adjusting the overall height of the operating frame, so that the user can adjust the processing height of the circuit board according to the requirements.

[0038] A measuring rod 16 is fixedly connected to the positioning block 5, and a limiting block 17 for restricting the freedom of the measuring rod 16 is fixedly connected to the mounting frame 4. When the mounting frame 4 slides away from the positioning block 5, the limiting block 17 will slide against the measuring rod 16. The user can determine the downward sliding distance of the mounting frame 4 according to the scale on the measuring rod 16, and thus determine the downward movement distance of the circuit board.

[0039] The mounting post 3 is fitted with a limiting ring 18, on which a limiting bolt 19 is threadedly connected. A timer 20 is connected to the limiting ring 18, and a push switch 181 electrically connected to the timer 20 is also connected to the limiting ring 18. The user can screw the limiting ring 18 onto the mounting post 3 at a suitable position using the limiting bolt 19, thereby limiting the sliding of the mounting frame 4 on the mounting post 3 and preventing the mounting frame 4 from causing the PBC board to be over-immersed in the solder. The user can also observe the immersion time of the PBC board in the solder through the timer 20. When the mounting frame 4 touches the limiting ring 18, the mounting frame 4 will press the push switch 181, which will connect the circuit of the timer 20, and the timer 20 will start timing to accurately count the immersion time of the PBC board in the solder. The timer 20 can also integrate a buzzer. When the timer 20 reaches the set time, the buzzer will sound an alarm to remind the operator. In addition, the position of the timer 20 can be adjusted according to needs and installed in a suitable position.

[0040] In one implementation, reference is made to Figure 3 The clamping piece 14 branches into multiple forked rods below, and each forked rod is provided with multiple protrusions. The spacing of each protrusion 15 is different, and the multiple spacings can be set to 1.2, 1.4, 1.8 and 2.2 respectively, for clamping PBC boards of different thicknesses.
