The high-temperature liquid tin maintains an inclined plane, and a special device makes the liquid tin form a phenomenon similar to waves, so it is called "wave soldering". Its main material is solder wire. Wave soldering refers to melting the soft soldering material (lead-tin alloy), spraying it into a solder wave peak of the designed requirement by an electric pump or an electromagnetic pump, or forming it by injecting nitrogen into the solder bath, so that the printed board pre-installed with components passes through the solder wave peak to realize the mechanical and electrical connection between the solder ends or pins of the components and the solder pads of the printed board. At present, during the use of the guide rails on wave soldering machines, due to external factors such as heating, movement, and application of different loads, there may be slight geometric deformations, resulting in the printed circuit board passing through the guide rails not smoothly and affecting the welding quality.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 3 shown, a deformation prevention structure for a wave soldering machine provided by the present invention includes a fixed seat 1, a guide rail 2, a fixed plate 3, a hydraulic cylinder one 4 and a hydraulic cylinder two 5.

The reciprocating lead screw 92 drives the installation seat 6 to reciprocate, so that the installation seat 6 can drive the cleaning frame 7 inside the wall to move, and further enables the brush 8 to reciprocally clean the inside of the guide rail 2, so that the residue is separated from the inner wall of the guide rail 2.

[0025] Reference Figure 1 and Figure 3 As shown in Figure 1 and Figure 3 , the positioning component 10 includes a mounting bracket 101. The mounting bracket 101 is fixedly connected to the front side and the rear side of the mounting base 6. A positioning rod 102 is movably connected to the inner wall of the mounting bracket 101. Positioning grooves 103 are formed on both sides of the cleaning frame 7. The surface of the positioning rod 102 is movably connected to the inner wall of the positioning groove 103.

One end of the spring 104 is fixedly connected to the surface of the positioning rod 102, and the other end of the spring 104 is fixedly connected to the inner wall of the mounting bracket 101.

[0026] As a technical optimization scheme of the present utility model, by providing the positioning component 10, the cleaning frame 7 can be effectively placed into the interior of the mounting base 6. At this time, the acting force of the spring 104 pushes the positioning rod 102 to move, so that the positioning rod 102 moves inward on the inner wall of the mounting bracket 101 and the positioning rod 102 is moved to the inner wall of the positioning groove 103, thereby completing the positioning of the cleaning frame 7, facilitating the installation of the cleaning frame 7 by the user, and improving the stability during the cleaning of the brush 8.

[0028] As a technical optimization scheme of the present utility model, by providing the pull plate 11 and the pull ring 12, when the cleaning frame 7 is used up, at this time, by the combined use of the pull plate 11 and the pull ring 12, the positioning rod 102 can be pulled out from the inner wall of the positioning groove 103, facilitating the disassembly of the cleaning frame 7 by the user.

[0030] As a technical optimization scheme of the present utility model, by providing the ball bearings 13 and the sliding groove 14, when the mounting base 6 moves, the ball bearings 13 can be effectively driven to move therewith, and the ball bearings 13 can slide on the inner wall of the sliding groove 14, thereby improving the smoothness during the adjustment of the mounting base 6.

[0031] Reference Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , protective pads 15 are provided on both sides of the brush 8, and the inner side of the protective pads 15 is fixedly connected to the surface of the cleaning frame 7.

[0032] As a technical optimization solution of the present utility model, by providing a protective pad 15, the protective pad 15 can be effectively fixed on the surface of the cleaning frame 7. When the cleaning frame 7 moves inside the inner wall of the guide rail 2, the inner wall of the guide rail 2 can be protected by the protective pad 15 to prevent the cleaning frame 7 from rubbing against the inner wall of the guide rail 2 and affecting its service life.

[0033] Reference Figure 2 and Figure 3 , a scraping block 16 is provided inside the brush 8, and the top of the scraping block 16 is fixedly connected to the bottom of the cleaning frame 7.

[0034] As a technical optimization solution of the present utility model, by providing the scraping block 16, the scraping block 16 can be effectively driven to move along with the movement of the cleaning frame 7 while the cleaning frame 7 moves, so that the scraping block 16 can scrape the residues inside the guide rail 2 to prevent the residues from being adsorbed inside the guide rail 2 and being difficult to clean, thereby improving the cleaning efficiency of the guide rail 2.

[0035] The working principle and usage process of the present utility model: When in use, through the hydraulic cylinders 4 and 5 installed between the guide rail 2 and the fixing plate 3, the guide rail 2 can be subjected to hydraulic adjustment as needed to prevent the guide rail 2 from deforming. After the guide rail 2 has been used for a long time, the user puts the cleaning frame 7 into the inside of the mounting seat 6. At this time, the positioning rod 102 is pushed to move by the acting force of the spring 104, so that the positioning rod 102 moves inward on the inner wall of the mounting frame 101 and moves the positioning rod 102 to the inner wall of the positioning groove 103, thereby completing the positioning of the cleaning frame 7, facilitating the user to install the cleaning frame 7, and improving the installation efficiency of the cleaning frame 7. After the cleaning frame 7 is installed, then the user starts the driving motor 91 to drive the reciprocating lead screw 92 to rotate, so that the reciprocating lead screw 92 drives the cleaning frame 7 to reciprocate through the mounting seat 6. Subsequently, while the cleaning frame 7 moves, the brush 8 driven by it can clean the inner wall of the guide rail 2, so that the residues are separated from the guide rail 2, thereby facilitating the user to clean the guide rail 2 and improving the service life of the guide rail 2. During the cleaning process of the guide rail 2, the scraping block 16 at the bottom of the cleaning frame 7 moves along with it, so that the scraping block 16 can scrape the inside of the guide rail 2, thereby improving the cleaning effect inside the guide rail 2 and preventing the residues from being adsorbed on the inner wall of the guide rail 2.

[0036] In summary, for the anti-deformation structure of a wave soldering machine, by providing the mounting seat 6, the cleaning frame 7, the brush 8 and the driving component 9, it can effectively drive the mounting seat 6 to move by the driving component 9, and install the cleaning frame 7 inside the mounting seat 6, so that the mounting seat 6 drives the cleaning frame 7 to reciprocate, thereby being able to clean the inner wall of the guide rail 2, separate the residues from the inside of the guide rail 2, improve the service life of the guide rail 2, and solve the problem that due to the lack of a guide rail cleaning structure, the solder dross and impurities generated during soldering will fall into the inside of the guide rail, which is not convenient for the user to clean the solder dross, and the residues on the guide rail will increase the friction during the operation of the guide rail, thereby reducing the service life of the guide rail.
