Description

Technical Field

[0001] This utility model relates to the technical field of circuit board component welding, and in particular to an auxiliary device for circuit board component welding. Background Technology

[0002] Circuit boards are miniaturized and visualized circuits, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit board component soldering refers to soldering electronic components onto the circuit board. In order to realize the different functions of different circuit boards, relevant electrical components need to be soldered onto the circuit board, which is the most basic process of installing each electronic component in electronic circuit assembly.

[0003] When soldering circuit board components, the heated soldering station clamp is gently brought into contact with the solder joint, and the solder is heated at the same time. After the solder melts, the soldering station clamp is separated from the solder joint, and the soldering is completed. While waiting for the solder to solidify again, the electronic components are stably soldered on the circuit board.

[0004] However, existing soldering processes lack effective structures for fixing the circuit board position and positioning the soldering position. Therefore, during soldering, the solder position may shift relative to the soldering position of the circuit board components, which in turn causes the liquid generated by the melting solder to shift, thus affecting the soldering effect. Furthermore, after soldering, the solder liquid usually cools naturally, resulting in low overall cooling efficiency, which in turn affects the overall soldering efficiency of the circuit board.

[0005] To address these issues, we propose a circuit board component soldering auxiliary device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary device for soldering circuit board components.

Adjustment frames are respectively provided on the left and right sides of the support frame. Clamping springs are connected between the adjustment frames and the side walls of the support frame. Clamping plates are rotatably connected to the upper sides of the adjustment frames on both sides. A horizontal positioning frame is provided on the upper side of the support frame, and a positioning ring is provided inside the positioning frame.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-4A circuit board component soldering auxiliary device includes a support frame 1, with legs connected to the lower end face of the support frame 1. A friction layer is covered on the lower end face of the legs to increase friction and ensure the stability of the device. The support frame 1 is C-shaped, with adjustment frames 2 on both sides. The adjustment frames 2 are designed for adjustable position, allowing the device to be used with circuit boards of different sizes by adjusting their positions. Clamping springs 3 connect the adjustment frames 2 to the side walls of the support frame 1. Under the elastic force of the clamping springs 3, the adjustment frames 2 on both sides can move inward, thereby clamping and fixing the inner circuit board 2. Guide grooves 301 are formed on the side walls of the support frame 1 above and below the clamping springs 3. Guide rods 302 are connected to the side walls of the adjustment frames 2, with one end of the guide rod 302 extending into the guide groove 301. The two work together to adjust the adjustment frames 2. The adjustment direction is guided to prevent the adjustment frame 2 from shifting. The upper sides of the two adjustment frames 2 are respectively rotatably connected to clamping plates 4, and the inner walls are covered with rubber pads to increase friction while avoiding damage to the circuit board structure. The clamping plates 4 are L-shaped, which can more stably clamp and limit the circuit board. The corner of the outer side wall of the clamping plate 4 is inclined. Simply press the circuit board down on the upper side of the clamping plate 4, and the clamping plate 4 can be pushed to rotate outward under the action of the component force, so as to facilitate the quick installation of the circuit board into the support frame 1 and the adjustment frame 2. The side wall of the clamping plate 4 has a slot 401. The inner wall of the adjustment frame 2 is connected to the main shaft 402, which runs longitudinally through the slot 401. A coil spring 403 is connected between the main shaft 402 and the inner wall of the slot 401. Under the elastic force of the coil spring 403, the clamping plate 4 can rotate and reset. After the circuit board is installed, it can provide a limiting effect under the action of the elastic force.

[0028] Based on the above structure, the present invention has the following embodiments:

[0029] When using the device, move it to the desired position, then take out the circuit board to be soldered. According to the actual size of the circuit board, pull the adjustment frames 2 on both sides outward so that the fixed structure composed of the adjustment frames 2 and the support frame 1 matches the size of the circuit board. Then place the circuit board on the upper side of the clamping plate 4 and press the circuit board down to separate and push the clamping plate 4 to rotate outward and open. At this time, the circuit board enters between the clamping plates 4 on both sides and enters the fixed structure composed of the adjustment frames 2 and the support frame 1. Under the elastic force of the coil spring 403, the clamping plate 4 rotates back to its original position, thereby clamping and fixing the circuit board to ensure its stability.

[0030] Reference Figure 4-5A horizontal positioning frame 5 is provided on the upper side of the support frame 1. A guide rail 501 is provided on the inner wall of one side of the support frame 1. An installation block 502 is provided on the inner side of the guide rail 501. The adjacent side wall surfaces of the two are covered with a smooth layer to facilitate sliding cooperation between the two. The lateral position of the positioning frame 5 and the positioning ring 6 can be adjusted. One end of the installation block 502 extends to the outside of the guide rail 501. The positioning frame 5 and the installation block 502 are rotatably connected. When not in use, the positioning frame 5 can be rotated away to avoid affecting the disassembly and assembly of the circuit board. A positioning ring 6 is provided on the inner side of the positioning frame 5. By aligning the positioning ring 6 with the welding position, the welding position is positioned, making it easier for the user to find the welding position and avoiding displacement during the welding process. Sliding grooves 601 are provided on the inner walls of both sides of the positioning frame 5. The side wall of the positioning ring 6 extends into the sliding groove 601. The adjacent side wall surfaces of the two are covered with a smooth layer to facilitate sliding cooperation between the two. The longitudinal position of the positioning ring 6 can be adjusted by sliding.

[0031] Based on the above structure, the present invention has the following embodiments:

[0032] During welding, rotate the positioning frame 5 to position it laterally on the upper side of the circuit board. Then, through the sliding engagement of the mounting block 502 and the guide rail 501, and the engagement of the slide groove 601 and the side wall of the positioning ring 6, adjust the position of the positioning ring 6 on the upper side of the circuit board so that the positioning ring 6 coincides with the welding position on the circuit board, and then perform the welding work.

[0033] Reference Figure 5 An air pump 7 is installed on the side wall of the support frame 1. The air pump is a D50 series miniature air pump, which is easy to install and use and is small enough not to affect the welding work. The side wall is equipped with a matching drive power supply and control buttons to control the operation of the air pump 7. A conduit 701 connects the air pump 7 to the positioning ring 6. An annular groove 702 is opened in the positioning ring 6. Air holes 8 are opened on the inner wall and the lower side wall of the positioning ring 6, respectively. The air holes 8 are connected to the inner cavity of the annular groove 702. When the air pump 7 runs, it can drive the external air circulation conduit, the annular groove 702 and the air holes 8 to blow and cool the solder liquid at the welding point, so as to cool it quickly and avoid affecting the subsequent welding work.

[0034] Based on the above structure, the present invention has the following embodiments:

[0035] After the soldering is completed, the air pump 7 is controlled to drive the external air circulation duct, annular groove 702 and air hole 8 to blow and cool the solder liquid at the soldering point, so that it cools down quickly. After cooling, the position of the positioning ring 6 is adjusted again to carry out the soldering of other electronic components. After the entire circuit board components are soldered, the positioning frame 5 is rotated to open, and then the clamping plate 4 is rotated to both sides to release the restriction on the circuit board. After that, the soldered circuit board is taken out.

[0036] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
