[0002] A soldering machine is a device used for automated soldering of electronic components. Its core consists of a temperature-controlled soldering iron system, a solder feeding mechanism, and a precision motion module. Through program control, it precisely positions the soldering iron tip to the solder joint, and then the solder feeding mechanism delivers a measured amount of solder wire to the tip, where it is heated and melted to complete the soldering process. It is widely used in electronic manufacturing fields such as PCB assembly.

[0003] In the prior art, Chinese utility model with publication number CN223222620U discloses an easy-to-adjust automatic soldering machine. By setting up slide rails, sliders, etc., the slider can move within the slide rails to adjust the height up, down, left, and right. It is suitable for different soldering items, is easy to adjust, and does not require a lot of time, saving time and effort.

[0004] However, currently, the adjustment and movement speed of traditional soldering machines is mostly a fixed value. When dealing with multiple solder joints on a PCB substrate, the soldering machine wastes a lot of time in the adjustment and movement process, resulting in low soldering efficiency. To address this problem, this invention proposes a soldering machine that is easy to adjust. Utility Model Content

[0005] The purpose of this invention is to provide a soldering machine that is easy to adjust, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soldering machine that is easy to adjust, comprising: A conveyor frame, with a self-fixed guide frame above it, a sliding seat slidably mounted on the outside of the guide frame, and a soldering iron mounted on the lower side of the sliding seat; A connecting block is fixed on the sliding seat. A transmission belt is provided in the inner cavity of the guide frame. The connecting block is fixed to one side of the transmission belt. The other side of the transmission belt is fixedly connected to the guide frame through a fixing plate. A positioning frame for positioning is provided in the middle of the transmission belt. Pull rope one and pull rope two are fixed on the connecting block and the positioning frame respectively. Pull rope one and pull rope two are respectively wound around the outside of take-up roller one and take-up roller two. When take-up roller one and take-up roller two rotate independently, they pull the connecting block to slide through pull rope one and pull rope two respectively. Both take-up roller one and take-up roller two are rotatably sleeved on the outside of the fixed shaft. A polygonal rotating shaft parallel to the fixed shaft is provided on the outside of the fixed shaft. A drive gear is slidably sleeved on the outside of the polygonal rotating shaft. Gear one and gear two are respectively fixed on the side of take-up roller one and take-up roller two that are close to each other. The drive gear slides and meshes with one of gear one and gear two.

[0007] Preferably, the middle portions of the first pull rope and the second pull rope are respectively wound around the first and the second take-up rollers once and once, respectively. Both ends of the inner cavity of the guide frame are rotatably mounted with reversing shafts. The two ends of the first pull rope are respectively wound around the reversing shafts half a turn and fixed to the connecting block. The two ends of the second pull rope are respectively wound around the reversing shafts half a turn and fixed to the positioning frame.

[0008] Preferably, a fixed seat is fixed at the lower end of the fixed shaft, and the fixed seat is fixedly connected to the guide frame. A forward and reverse motor is fixed on the surface of the fixed seat, and a polygonal rotating shaft is fixed to the output end of the forward and reverse motor.

[0009] Preferably, a top plate is fixed to the upper end of the fixed shaft, an electromagnet is fixed to the lower surface of one end of the top plate, and a magnetic ring is fixed to the upper surface of the drive gear, with the magnetic ring corresponding to the electromagnet.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a take-up roller 1 and a take-up roller 2 rotatably mounted on the outside of a fixed shaft. Pull ropes 1 and 2 are wound around the outside of the take-up rollers 1 and 2 respectively. The two ends of pull rope 1 are fixed to a connecting block, and the two ends of pull rope 2 are fixed to a positioning frame. A drive gear is slidably mounted on the outside of a polygonal rotating shaft. By adjusting the position of the drive gear, when the drive gear meshes with gear 1, the take-up roller 1 rotates and pulls the connecting block through pull rope 1, thereby causing the sliding seat to move at a low speed. When the drive gear meshes with gear 2, the take-up roller 2 rotates and pulls the positioning frame through pull rope 2, at which point the transmission belt can drive the connecting block to move rapidly at twice the speed of the positioning frame, thus shortening the time spent moving the soldering iron. This device allows adjustment of the soldering iron's moving speed according to usage requirements, thereby improving soldering efficiency. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1, please refer to Figures 1-5 This utility model provides a technical solution: a soldering machine that is easy to adjust, including: a conveyor frame.

[0017] Specifically, a self-fixed guide frame 2 is set above the conveyor frame, and a sliding seat 3 is slidably installed on the outside of the guide frame 2. A soldering iron 4 is installed on the lower side of the sliding seat 3. Figure 1 As shown, the sliding base 3 can slide along the length of the guide frame 2 to adjust its position. The soldering iron 4 is rotatably mounted on the lower side of the sliding base 3 by a hinge ball known in the prior art. The orientation of the soldering iron 4 can be changed by rotating the hinge ball. In addition, an automatic solder dispensing device known in the prior art is provided next to the soldering iron 4, which will not be described in detail here. Secondly, a connecting block 31 is fixed on the sliding seat 3, such as Figure 2As shown, the guide frame 2 itself is a hollow structure. The sliding seat 3 and the guide frame 2 are slidably connected through the cooperation of a slider and a groove, which are known in the prior art. The connecting block 31 is located in the inner cavity of the guide frame 2. A transmission belt 5 is provided in the inner cavity of the guide frame 2. The connecting block 31 is fixed to one side of the transmission belt 5. The other side of the transmission belt 5 is fixedly connected to the guide frame 2 through a fixing plate 51. A positioning frame 52 is provided in the middle of the transmission belt 5 for positioning. Figure 3 As shown, the positioning frame 52 supports the entire transmission belt 5 to prevent deformation. Since the fixed plate 51 is fixed to the guide frame 2, when the positioning frame 52 moves, the transmission belt 5 will rotate around the rollers at both ends, thereby driving the connecting block 31 to slide at twice the speed of the positioning frame 52. Pull rope 6 and pull rope 7 are fixed on the connecting block 31 and the positioning frame 52, respectively. Pull rope 6 and pull rope 7 are wound around the outside of take-up roller 61 and take-up roller 71, respectively. When take-up roller 61 and take-up roller 71 rotate individually, they pull the connecting block 31 to slide through pull rope 6 and pull rope 7, respectively. Figure 4 As shown, when the take-up roller 61 rotates alone, the pull rope 6 directly pulls the connecting block 31 to slide. When the take-up roller 71 rotates alone, the take-up roller 71 first pulls the positioning frame 52 to slide, and the positioning frame 52 then drives the connecting block 31 to slide through the transmission belt 5. Therefore, the connecting block 31 has two different speeds, and the ratio of the two speeds is one-half. In other words, this device can control the speed of sliding of the sliding seat 3 by controlling the rotation of the take-up roller 61 alone or controlling the rotation of the take-up roller 71 alone. Furthermore, both take-up roller 61 and take-up roller 71 are rotatably sleeved on the outside of the fixed shaft 8. The fixed shaft 8 itself does not rotate, while take-up roller 61 and take-up roller 71 can rotate independently. A polygonal rotating shaft 92 parallel to the fixed shaft 8 is provided on the outside of the fixed shaft 8. A drive gear 93 is slidably sleeved on the outside of the polygonal rotating shaft 92. Gear 62 and gear 72 are fixed on the sides of take-up roller 61 and take-up roller 71 that are close to each other, respectively. The drive gear 93 slides and meshes with one of gear 62 and gear 72, such as... Figure 5 As shown, when the drive gear 93 slides upward along the length of the polygonal shaft 92, the drive gear 93 can mesh with gear 62. At this time, the polygonal shaft 92 rotates, and the meshing of the drive gear 93 with gear 62 can drive the take-up roller 61 to rotate independently. When the drive gear 93 slides downward, the drive gear 93 can mesh with gear 72. At this time, the rotation of the drive gear 93 can drive the take-up roller 71 to rotate independently.

[0018] To allow the connecting block 31 or the positioning frame 52 to slide forward or backward, the middle portions of the pull rope 6 and pull rope 7 of this application are respectively wound around the winding roller 61 and winding roller 71 once each. Reversing shafts 21 are rotatably mounted at both ends of the inner cavity of the guide frame 2. The two ends of pull rope 6 are respectively wound around the reversing shaft 21 half a turn and fixed to the connecting block 31, and the two ends of pull rope 7 are respectively wound around the reversing shaft 21 half a turn and fixed to the positioning frame 52. Figure 3 and Figure 4 As shown, when the take-up roller 61 rotates forward, one end of the pull rope 6 pulls the connecting block 31 to slide, and the other end of the pull rope 6 is unwound, thus preventing the connecting block 31 from being pulled by the other end of the pull rope 6 and thus being unable to be pulled. Conversely, when the take-up roller 61 rotates in reverse, the other end of the pull rope 6 pulls the connecting block 31 to slide in the opposite direction. Similarly, the pull rope 7 can also pull the positioning frame 52 to slide in the forward or reverse direction.

[0019] To control the sliding stroke of the drive gear 93, this application also includes a fixed seat 9 fixed at the lower end of the fixed shaft 8, and the fixed seat 9 is fixedly connected to the guide frame 2. Both the fixed seat 9 and the fixed shaft 8 are fixed to the guide frame 2. A forward and reverse motor 91 is fixed on the surface of the fixed seat 9, and a polygonal rotating shaft 92 is fixed to the output end of the forward and reverse motor 91. Therefore, when the forward and reverse motor 91 rotates, it can drive the polygonal rotating shaft 92 to rotate, thereby providing power for the rotation of the drive gear 93. Retaining rings that limit the sliding of the drive gear 93 are fixed at both the upper and lower ends of the polygonal rotating shaft 92 to control the up and down sliding stroke of the drive gear 93 and prevent the drive gear 93 from sliding too far and causing misalignment with gear 62 (or gear 72).

[0020] In order to control the up and down sliding of the drive gear 93, this application also has a top plate 81 fixed at the upper end of the fixed shaft 8, an electromagnet 82 fixed on the lower surface of one end of the top plate 81, and a magnet ring 94 fixed on the upper surface of the drive gear 93, with the magnet ring 94 corresponding to the electromagnet 82. Since the magnet ring 94 is fixed on the upper surface of the drive gear 93 and the magnetic poles on the upper side of the magnet ring 94 are fixed, the orientation of the magnetic poles of the electromagnet 82 can be controlled by an external controller to achieve mutual attraction or repulsion between the electromagnet 82 and the magnet ring 94, thereby controlling the drive gear 93 to move up or down.

[0021] To achieve more precise control over the sliding of the sliding seat 3, gear 62 and gear 72 of this application have the same diameter and the same number of teeth. The diameter of the drive gear 93 is smaller than that of gear 62. The meshing transmission between the drive gear 93 and gear 62 (or gear 72) is a reduction transmission, which can more precisely control the rotation angle of the take-up roller 61, thereby ensuring more precise sliding of the sliding seat 3. A polygonal through hole adapted to the polygonal rotating shaft 92 is provided in the middle of the drive gear 93 to ensure that the drive gear 93 and the polygonal rotating shaft 92 can only slide relative to each other and will not rotate relative to each other.

[0022] To prevent gear 62 and gear 72 from meshing with drive gear 93 simultaneously, take-up roller 61 and take-up roller 71 are rotatably connected to fixed shaft 8 via bearings. Therefore, the relative positions of take-up roller 61 and take-up roller 71 on fixed shaft 8 do not change, and take-up roller 61 and take-up roller 71 can only rotate. A gap is left between gear 62 and gear 72, and the width of the gap is not less than the width of drive gear 93. When drive gear 93 slides up and down, drive gear 93 will not mesh with gear 62 and gear 72 simultaneously, thereby preventing pull rope 6 or pull rope 7 from being broken.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
