Electrical components such as capacitors and resistors are fixed on circuit boards by soldering. When repairing or replacing existing electrical components such as capacitors, circuit boards are easily moved due to the lack of effective restraint, which affects the accuracy of soldering. Furthermore, when multiple capacitors are soldered in sequence, the solder residue left from the previous capacitor can easily scatter on the circuit board, interfering with the soldering of subsequent capacitors and affecting the accuracy and quality of capacitor soldering. Utility Model Content

[0003] The purpose of this invention is to provide a capacitor welding device for electronic device circuit boards. It can solve the technical problems of circuit board movement and solder slag residue affecting welding quality during capacitor welding of existing circuit boards. It can effectively limit and fix the circuit board and remove the solder slag residue in time, thus ensuring the accuracy and quality of welding.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A capacitor soldering device for electronic device circuit boards includes a soldering table for soldering the circuit board, the circuit board having multiple capacitors, a vertical plate on one side of the soldering table, a dust suction chamber inside the vertical plate, a dust suction pipe connected to the dust suction chamber, multiple dust suction holes communicating with the dust suction chamber on the vertical plate, a front baffle slidably connected to the soldering table, and side blocks symmetrically slidably connected to both sides of the soldering table, each of the vertical plate, front baffle, and side blocks having a support block that contacts the bottom of the circuit board, a clamping spring between the side blocks and the soldering table, and a limiting bracket slidably connected to the front baffle for use with the side blocks.

[0006] Furthermore, the welding platform is provided with a power groove, and the front baffle and side block are slidably connected in the power groove. The power groove is provided with a locking pin that works in conjunction with the front baffle.

[0007] Furthermore, the locking pin penetrates the side wall of the power groove and is threadedly connected to it. The end of the locking pin is rotatably connected to the front baffle. The front baffle is provided with multiple guide pins, which penetrate the side wall of the power groove and are slidably connected to it.

[0008] Furthermore, the cross-section of the limiting frame is U-shaped, with both sides of the U-shape passing through and slidably connected to the front baffle. The end of the U-shape contacts the side stop block, and the front baffle is provided with an adjustment column for use with the limiting frame.

[0009] Furthermore, the adjusting column passes through the front baffle and is threadedly connected to it, the end of the adjusting column is rotatably connected to the limiting frame, and the end of the limiting frame is magnetically attracted to the side stop block.

[0010] Furthermore, the bottom of the suction chamber is inclined toward the suction pipe, and a light strip is provided on the upright plate above the suction hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The structure of this utility model has a vertical plate on the welding table, and a dust suction chamber is provided inside the vertical plate. A dust suction pipe is connected to the dust suction chamber. Multiple dust suction holes connected to the dust suction chamber are provided on the side of the vertical plate facing the welding table. Multiple support blocks that contact the bottom of the circuit board are provided on the vertical plate. This structure allows the bottom of the circuit board to be located on the support blocks during welding, so that the back side of the circuit board contacts the vertical plate.

[0022] Reference Figure 1 and Figure 2This utility model describes a capacitor 3 welding device for a circuit board 1 of an electronic device. The main structure includes a welding table 2 for welding the circuit board 1, which provides support. Multiple capacitors 3 are mounted on the circuit board 1 and are fixed to it by welding. A vertical plate 4 is fixed to one side of the welding table 2 by welding or integral molding. The vertical plate 4 extends vertically and is perpendicular to the welding table 2. A dust suction chamber 5 is provided inside the vertical plate 4, and a dust suction pipe 6 is connected to the dust suction chamber 5. The dust suction pipe 6 is connected to an external dust suction system, generating suction within the dust suction chamber 5. Multiple dust suction holes 7 are provided on the vertical plate 4, communicating with the dust suction chamber 5. The suction hole 7 is located on the side of the upright plate 4 facing the welding table 2, penetrating the side wall of the suction chamber 5. This allows the side of the upright plate 4 facing the welding table 2 to generate suction through the multiple suction holes 7. When the circuit board 1 is placed on the welding table 2, the multiple suction holes 7 on the upright plate 4 can generate suction on the circuit board 1, effectively removing welding slag and preventing residual slag from interfering with the subsequent welding of the capacitor 3, thus ensuring welding accuracy. A front baffle 8 is slidably connected to the welding table 2, contacting the front side of the circuit board 1 after sliding. The upright plate 4 contacts the rear side of the circuit board 1. Side blocks 9 are symmetrically slidably connected to both sides of the welding table 2. The stop block 9 contacts the left and right sides of the circuit board 1. Preferably, the side stop block 9 is equipped with anti-slip paddles to improve the accuracy and convenience of moving the side stop block 9. The upright plate 4, the front baffle 8, and the side stop block 9 are all equipped with support blocks 10 that contact the bottom of the circuit board 1. This structure allows the upright plate 4, the front baffle 8, and the side stop block 9 to contact the sides of the circuit board 1 in various directions, effectively restricting the placement of the circuit board 1 and improving the firmness of the circuit board 1 during soldering. At the same time, the support blocks 10 can contact the bottom of the circuit board 1 to achieve effective vertical support for the circuit board 1. A clamping spring 11 is provided between the side stop block 9 and the soldering table 2. This structure... Before placing the circuit board 1, simply sliding the side blocks 9 to both sides compresses the clamping spring 11. After releasing the side blocks 9, the elastic force of the clamping spring 11 is reduced, allowing the side blocks 9 to automatically clamp on both sides of the circuit board 1, forming an adaptive clamping of the circuit board 1. This provides a more secure clamping and prevents damage to the circuit board 1 from compression. The front baffle 8 is slidably connected to a limiting frame 12 that works in conjunction with the side blocks 9. The limiting frame 12 further restricts and fixes the position of the side blocks 9 on both sides, preventing the side blocks 9 from moving or misaligning when the elastic force of the clamping spring 11 is insufficient. This further improves the firmness of the limiting and fixing of the circuit board 1, ensuring the accuracy and quality of the welding.

[0023] Preferred, refer to Figure 3 and Figure 4The welding table 2 is provided with a power groove 13, which is formed by a downward indentation from the top of the welding table 2. The front baffle 8 and the side block 9 are slidably connected in the power groove 13. The clamping spring 11 is provided between the side block 9 and the side wall of the power groove 13. Preferably, a limiting post is provided in the power groove 13. The limiting post passes through the side block 9 and is slidably connected to it. The clamping spring 11 is sleeved on the outside of the limiting post. The power groove 13 is provided with a locking post 14 that works with the front baffle 8. The locking post 14 is used to lock and fix the position of the front baffle 8 after it slides and contacts the front side of the circuit board 1, ensuring the firmness of the circuit board 1 in limiting and fixing.

[0024] Preferably, the locking pin 14 penetrates the side wall of the power groove 13 and is threadedly connected to it. The end of the locking pin 14 is rotatably connected to the front baffle 8 via a bearing. With this structure, rotating the locking pin 14 will drive its end to rotate and move under the action of the threaded connection, thereby causing the front baffle 8 with the rotating end to slide. Multiple guide pins 15 are welded or bolted to the front baffle 8. The guide pins 15 penetrate the side wall of the power groove 13 and are slidably connected to it. The multiple guide pins 15 provide guidance and restriction for the sliding of the front baffle 8, improve the firmness of the front baffle 8 in clamping and fixing the front side of the circuit board 1, and enable the rear side to fit more firmly on the upright plate 4, thereby improving the stability of the circuit board 1 position.

[0025] Preferred, refer to Figure 5 The limiting frame 12 has a U-shaped cross-section, with both sides of the U-shape passing through and slidably connected to the front baffle 8, making the sliding structure of the limiting frame 12 relative to the front baffle 8 more stable. The end of the U-shape contacts the side blocks 9. The front baffle 8 is provided with an adjusting column 16 for use with the limiting frame 12. The adjusting column 16 drives the limiting frame 12 to slide, so that its end contacts and presses against the side blocks 9 on both sides. The structure is simple and easy to operate, improving the convenience and stability of the limiting operation of the side blocks 9.

[0026] Preferably, the adjusting column 16 passes through the front baffle 8 and is threadedly connected to it. The end of the adjusting column 16 is rotatably connected to the limiting frame 12 via a bearing. With this structure, rotating the adjusting column 16 will drive the limiting frame 12 at its end to slide relative to the front baffle 8 under the action of the threaded connection. The threaded connection restricts the position of the limiting frame 12 after sliding. The end of the limiting frame 12 is magnetically attracted to the side block 9. After the limiting frame 12 slides laterally and comes into contact with the side block 9, the magnetic attraction further fixes the position of the side blocks 9 on both sides, effectively avoiding possible displacement of the side blocks 9 and further improving the firmness of the limiting and fixing of the side blocks 9.

[0027] Preferably, the bottom of the suction chamber 5 is inclined toward the suction pipe 6. This structure allows the welding slag and impurities entering the suction chamber 5 to roll smoothly down the inclined bottom toward the suction pipe 6, making the suction of welding slag more thorough, avoiding residue in the suction chamber 5, and reducing the difficulty of subsequent cleaning. A light strip 17 is provided on the upright plate 4 above the suction hole 7. Specifically, an LED light strip 17 can be used. Since the capacitor 3 is relatively small, the light strip 17 can illuminate the welding position, making the welding of the capacitor 3 more efficient and accurate.

[0028] Working Principle: The structure of this utility model features a vertical plate 4 on the welding table 2. The vertical plate 4 has a dust collection chamber 5 inside, connected to a dust collection pipe 6. Multiple dust collection holes 7, communicating with the dust collection chamber 5, are located on the side of the vertical plate 4 facing the welding table 2. Multiple support blocks 10, which contact the bottom of the circuit board 1, are also located on the vertical plate 4. This structure ensures that during welding, the bottom rear of the circuit board 1 rests on the support blocks 10, allowing the rear of the circuit board 1 to contact the vertical plate 4. This allows the multiple dust collection holes 7 on the vertical plate 4 to promptly remove the solder slag generated during the welding of capacitors 3 on the circuit board 1, preventing interference from solder slag during the welding of multiple capacitors 3 and ensuring the accuracy and quality of the capacitor welding. A front baffle 8 is slidably connected to the welding table 2. After the front baffle 8 slides, it contacts the front side of the circuit board 1. Side blocks 9 are symmetrically slidably connected to both sides of the welding table 2. A clamping spring 11 is provided between the side blocks 9 and the welding table 2. A limiting bracket 12 that works with the side blocks 9 is slidably connected to the front baffle 8. This structure can compress the clamping spring 11 by sliding the side blocks 9 on both sides, so that the side blocks 9 are clamped and fixed to both sides of the circuit board 1 under the elastic force of the clamping spring 11. Then, the front baffle 8 is slid to contact the front side of the circuit board 1, and the limiting bracket 12 on the front baffle 8 is slid to limit and fix the position of the side blocks 9 on both sides, thereby ensuring the firmness of clamping and fixing the circuit board 1. This makes it difficult for the circuit board 1 to move during the welding of the capacitor 3, thus ensuring the quality of the welding of the capacitor 3.
