Technical Field

[0001] This invention belongs to the technical field of soldering equipment and relates to a soldering device for convenient welding of metal materials. Background Technology

[0002] Soldering is a welding method that uses low-melting-point metal solder to melt and penetrate into and fill the gaps at the joints of metal parts.

[0003] Current soldering equipment often lacks automatic wire replenishment, requiring manual replacement of the solder wire once a roll is used up. Frequent wire roll replacements reduce soldering efficiency and also cause inconvenience.

[0004] To address the above problems, this invention proposes a soldering device for convenient welding of metal materials. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a soldering device for convenient welding of metal materials.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A soldering device for convenient metal material welding includes: an operating table, a first housing is horizontally movable on the operating table, a discharge pipe is installed on one side of the lower end of the first housing; a first belt is rectangularly mounted on the first housing; a plurality of solder wire spools are rotatably mounted on the first belt at intervals, and solder wire is wound on the solder wire spools.

[0007] Two limiting wheels are installed on the first housing. The gap between the two limiting wheels is greater than the outer diameter of the solder wire tube. The solder wire tube is located directly above the two limiting wheels. The axis of the limiting wheels is parallel to the axis of the solder wire tube.

[0008] The first housing is also equipped with a drive assembly that gradually extends the solder wire out of the discharge tube.

[0009] Furthermore, the drive assembly includes two feed rollers, and two motors are fixedly mounted on the first housing. The two motors correspond one-to-one with the two feed rollers, and the feed rollers are coaxially fixedly mounted on the motor shafts of the corresponding motors. The axis of the feed rollers is parallel to the axis of the limiting wheel.

[0010] Furthermore, a preheating pipe is installed at the outlet pipe, and a heating pipe is installed at the lower end of the preheating pipe.

[0011] Furthermore, a second housing is provided on one side of the first housing, and electric push rods are installed at the four corners of the first housing. The output end of the electric push rods is fixedly connected to the second housing.

[0012] Furthermore, four first pulleys are rotatably mounted on the first housing. The four first pulleys are located at the four corners of the rectangle. The first belt is tensioned and wound between the four first pulleys. The first belt is rectangular in shape. Multiple first fixing posts are spaced apart on the first belt. The solder wire tube is sleeved on the first fixing posts.

[0013] Furthermore, four second pulleys are rotatably arranged on the second housing, each corresponding to a first pulley. A second belt is tensioned and wound between the four second pulleys. Multiple second fixing posts are spaced apart on the second belt, each corresponding to a first fixing post. The first fixing posts and their corresponding first fixing posts are on the same horizontal line. A tin wire sleeve is fitted between the first fixing posts and the second fixing posts.

[0014] Furthermore, a rectangular telescopic rod is fixedly connected to the first pulley in the upper right corner, and the other end of the rectangular telescopic rod is fixedly connected to the corresponding second pulley.

[0015] Compared with the prior art, the present invention has the following beneficial effects: when the solder wire on the lowest solder wire drum is used up, it moves downward under the action of gravity, and causes the first belt to move.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-6 As shown, the technical solution adopted by the present invention is as follows: A soldering device for convenient metal material welding includes an operating table 1, a first housing 3, a solder wire spool 18, and solder wire 19 wound on the solder wire spool 18. A support plate is fixedly installed on the operating table 1, and an electrically controlled slide rail 2 is fixedly installed on the support plate. The electrically controlled slide rail 2 is equipped with an electric slider. The first housing 3 is fixedly connected to the electric slider. A discharge pipe is installed at the lower end of the first housing 3. A preheating pipe 4 is installed at the lower end of the discharge pipe, and a heating pipe 5 is installed at the lower end of the preheating pipe 4. The preheating pipe 4 preheats the solder wire 19, and the heating pipe 5 heats and melts the solder wire 19, making it convenient to apply the solder wire 19 to the position to be soldered. The first housing 3 slides along the electrically controlled slide rail 2, thereby completing the overall soldering work.

[0025] A first belt 7 is mounted on one side of the first housing 3 in a rectangular shape. Specifically, four first pulleys 8 are provided on the first housing 3, and the four first pulleys 8 are located at the four corners of the rectangle. The first belt 7 is tensioned and wound between the four first pulleys 8, making the first belt 7 as a whole rectangular. There is rotational damping between the first pulleys 8 and the first housing 3. A plurality of first fixing posts 9 are fixedly provided on the first belt 7 at intervals.

[0026] The first housing 3 is fitted with a second housing 13. Specifically, electric push rods 12 are fixedly installed at each of the four corners of the first housing 3, and the output ends of the electric push rods 12 are fixedly connected to the second housing 13. The extension and retraction of the electric push rods 12 causes the second housing 13 to move closer to or further away from the first housing 3.

[0027] Four second pulleys 15 are rotatably mounted on the second housing 13. Each second pulley 15 corresponds to a first pulley 8, and the second pulley 15 is opposite to its corresponding first pulley 8. Rotational damping exists between the second pulleys 15 and the second housing 13. A second belt 14 is tensioned and wound around the four second pulleys 15. Multiple second fixing posts 16 are spaced apart on the second belt 14. Each second fixing post 16 corresponds to a first fixing post 9, and the first fixing post 9 and its corresponding second fixing post 16 are on the same horizontal line. A solder wire spool 18 is rotatably sleeved between the corresponding second fixing post 16 and the first fixing post 9. Figure 2 As shown, multiple tin wire spools 18 wound with tin wire 19 are all located on the left side of the first housing 3, that is, on the left side of the first belt 7.

[0028] A rectangular telescopic rod 17 is fixedly connected to the first pulley 8 in the upper right corner, and the other end of the rectangular telescopic rod 17 is fixedly connected to the corresponding second pulley 15. This helps to keep the first belt 7 and the second belt 14 moving synchronously, and keeps the second fixed post 16 and the corresponding first fixed post 9 on the same horizontal line.

[0029] Two mounting seats 11 are fixedly installed on the first housing 3, located on either side of the left side of the first belt 7. Each mounting seat 11 has a rotatable limiting wheel 10, such that the gap between the two limiting wheels 10 is directly below the left-side solder wire spool 18. The gap between the two limiting wheels 10 is larger than the outer diameter of the solder wire spool 18. The gap between the two limiting wheels 10 should match the outer diameter of the solder wire spool 18. When there is no solder wire 19 on the solder wire spool 18, the solder wire spool 18 can pass between the two limiting wheels 10; when solder wire 19 is wound on the solder wire spool 18, the solder wire spool 18 cannot pass between the two limiting wheels 10. Initially, the solder wire spool 18 has solder wire 19 wound on it, and the two limiting wheels 10 support the lowermost part of the solder wire spool 18 on the left side. When the solder wire 19 on the lowest solder wire spool 18 is exhausted, under the action of gravity of multiple solder wire spools 18, the left side of the first belt 7 moves downward, thereby causing the first belt 7 to move as a whole, so that the lowest solder wire spool 18 passes between the two limit wheels 10 and moves to the lower side of the first belt 7.

[0030] The first housing 3 houses a drive assembly for moving the solder wire 19. The drive assembly includes two feed rollers 6. Both feed rollers 6 are rotatably mounted within the first housing 3. The axes of the feed rollers 6, the solder wire spool 18, and the limiting wheel 10 are parallel to each other. The outer end of the solder wire 19 on the lowest solder wire spool 18 passes between the two limiting wheels 10 and extends between the two feed rollers 6. Specifically, two motors are fixedly installed within the first housing 3, each corresponding to one of the two feed rollers 6. The feed rollers 6 are fixedly connected to the motor shafts of their respective motors. The two feed rollers 6 rotate relative to each other, causing the solder wire 19 between them to move downwards. The solder wire then passes sequentially through the discharge pipe, the preheating pipe 4, and the heating pipe 5.

[0031] Working principle: Initially, such as Figure 2 As shown, the solder wire spool 18 is rotatably sleeved between the first fixed post 9 and the second fixed post 16, and there is rotational damping between the solder wire spool 18 and the first fixed post 9 and the second fixed post 16, meaning that the solder wire spool 18 will not accidentally rotate around the first fixed post 9. Multiple solder wire spools 18 are located on the left side of the first belt 7. Solder wire 19 is wound on the solder wire spool 18, with the outer end of the solder wire 19 extending outwards and vertically downwards. The lowest solder wire spool 18 is positioned on the limiting wheel 10, and the outer end of the solder wire 19 on the lowest solder wire spool 18 passes through the limiting wheel 10 and extends between the two wire feeding rollers 6.

[0032] The motor and the electrically controlled slide rail 2 are started. The motor drives the two wire feeding rollers 6 to rotate relative to each other, causing the solder wire 19 between the two rollers 6 to gradually move downwards and pass through the preheating tube 4 and the heating tube 5 in sequence. The preheating tube 4 preheats the solder wire, and the heating tube 5 heats and melts the solder wire 19 and coats it onto the area to be soldered. At the same time, the lowest solder wire spool 18 rotates around the first fixed post 9, causing the solder wire 19 to gradually fall off the spool 18. The electrically controlled slide rail 2 drives the first housing 3 to move horizontally, thereby moving the heating tube 5 along the weld seam to complete the full soldering.

[0033] When the solder wire 19 on the lowest solder wire spool 18 is exhausted, the solder wire spool 18 can pass between the two limiting rollers 10. Multiple solder wire spools 18 move downwards under their own weight, causing the first belt 7 to move around the first pulley 8. The lowest solder wire spool 18 passes between the two limiting rollers 10, and then, as the first belt 7 moves, the lowest solder wire spool 18 moves from the left side of the first belt 7 to the lower side of the first belt 7. Simultaneously, the outer end of the solder wire 19 on the next solder wire spool 18 passes between the two limiting rollers 10 and gradually moves towards the wire feed roller 6, gradually moving onto the limiting roller 10. Under the support of the limiting roller 10, the solder wire spool 18 stops moving downwards, thereby stopping the first belt 7. Furthermore, the outer end of the solder wire spool 18 passes between the two limiting wheels 10 and extends between the two wire feeding rollers 6. Then, under the action of the two wire feeding rollers 6, it moves downward to complete the automatic feeding action and automatically feed the solder wire 19.

[0034] It should be noted that, since there is rotational damping between the first pulley 8 and the first housing 3, and between the second pulley 15 and the second housing 13, the first belt 7 moves slowly, which in turn makes the downward speed of the solder wire spool 18 less than the linear speed of the wire feeding roller 6, thus preventing the outer end of the solder wire 19 from abutting against the wire feeding roller 6 and causing the solder wire 19 to bend.

[0035] Thus, from bottom to top, all the solder wire 19 on the multiple solder wire spools 18 are used up. From bottom to top, when the solder wire 19 on the penultimate solder wire spool 18 is used up, because the solder wire 19 is relatively heavy, the uppermost solder wire spool 18 is able to overcome the rotational damping between the first pulley 8 and the first housing 3, the rotational damping between the second pulley 15 and the second housing 13, and the weight of the solder wire spool 18 on the right side of the first belt 7 that has used up its solder wire 19, so that the uppermost solder wire spool 18 can move downward under the action of gravity until it abuts against the two limit wheels 10, and automatically replenishes the solder wire 19.

[0036] When a wire needs to be replaced, start the electric push rod 12. The electric push rod 12 pushes the second housing 13 away from the first housing 3, so that the second fixing post 16 is disengaged from the corresponding solder wire spool 18. Stop the electric push rod 12 when the solder wire spool 18 can be easily removed from the first fixing post 9.

[0037] Subsequently, all the solder wire spools 18 are removed from the first belt 7, and new solder wire spools 18 with solder wire 19 wound on them are fitted onto the first fixed post 9. All the new solder wire spools 18 are positioned on the left side of the first belt 7, with all the new solder wire spools 18 above the limiting wheel 10, and the lowest solder wire spool 18 on the limiting wheel 10. The outer end of the solder wire 19 is pulled out by hand, making the outer end of the solder wire 19 vertically downwards. The outer end of the solder wire 19 on the lowest solder wire spool 18 passes between the two limiting wheels 10 and extends between the two wire feeding rollers 6.

[0038] Then, the electric push rod 12 is activated, causing it to shorten. The second housing 13 gradually approaches the first housing 3, and the second fixing post 16 gradually inserts into the corresponding solder wire spool 18. The electric push rod 12 is stopped when the second housing 13 is in contact with the first housing 3, completing the wire changing operation.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
