Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, and in particular to a tin wire rack with a quantitative wire output structure. Background Technology

[0002] A solder wire holder is a tool used to fix, support, and assist in the stable output of solder wire during soldering operations. Its core function is to improve soldering efficiency and precision. In fields such as electronics manufacturing, equipment maintenance, and DIY, soldering is a core process for connecting metal components or electronic parts. As a key consumable in the soldering process, the stability and accuracy of the solder wire output directly determine the solder joint quality, soldering efficiency, and solder wire utilization rate.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Traditional solder wire racks are mostly simple load-bearing structures that can only realize the placement and initial guidance of solder wire rolls. The delivery of solder wire depends entirely on the operator's manual pulling. This manual solder delivery method has significant defects: the force of manual pulling is difficult to control precisely, and uneven force can easily lead to excessive or insufficient solder wire delivery. Excessive delivery will cause solder wire waste and may cause poor solder joints or bridging. Insufficient delivery requires secondary soldering, which seriously affects the welding efficiency and the finished product qualification rate. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the traditional solder wire feeder relies entirely on manual pulling by the operator, which is prone to uneven force, resulting in excessive or insufficient solder wire output. To address this, we propose a solder wire feeder with a quantitative output structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a solder wire holder with a quantitative wire output structure, comprising a solder wire holder body and a placement rod; a handle is fixedly connected to the surface of the solder wire holder body; a solder wire spool is rotatably connected to the arc surface of the placement rod; the solder wire body is wound around the arc surface of the solder wire spool; a wire support frame is rotatably connected to one side of the solder wire holder body; the inner wall of the wire support frame is slidably connected to the solder wire body; a transmission device is provided on one side of the solder wire holder body; the transmission device includes two L-shaped plates, both of which are fixedly connected to one side of the solder wire holder body. A motor is fixedly connected to one side of the plates that are close to each other. A transmission roller is slidably inserted into the body of the solder wire frame. The transmission roller is fixedly connected to the output end of the motor. The other end of the transmission roller is rotatably connected to the body of the solder wire frame. A support plate is fixedly connected to the inner wall of the body of the solder wire frame. A threaded rod is threaded into the support plate. A rotating plate is fixedly connected to one end of the threaded rod. A U-shaped frame is rotatably connected to the end of the rotating plate away from the threaded rod. A round rod is fixedly connected to the inner wall of the U-shaped frame. A transmission cylinder is rotatably connected to the arc surface of the round rod. The arc surfaces of the transmission cylinder and the transmission roller are both in contact with the body of the solder wire.

[0006] Preferably, a guide rod is slidably inserted into the support plate, and one end of the guide rod is fixedly connected to the U-shaped frame.

[0007] Preferably, the arc surface of the transmission roller is provided with uniformly distributed anti-slip patterns, and the anti-slip patterns are distributed in a stripe pattern.

[0008] Preferably, a soft pad is fixedly connected to the arc surface of the transmission cylinder, and the soft pad is made of rubber.

[0009] Preferably, the surface of the wire support frame is provided with a fixing device, the fixing device includes a fixing plate, the fixing plate is fixedly connected to the surface of the wire support frame, a plurality of adjustment holes are opened on one side of the solder wire frame body, a fixing rod is slidably inserted in the fixing plate, the arc surface of the fixing rod is slidably connected to the adjustment holes, and a pull plate is fixedly connected to one end of the fixing rod.

[0010] Preferably, the arc surface of the fixing rod is fitted with a spring, and the two ends of the spring are fixedly connected to the fixing plate and the pull plate, respectively.

[0011] Preferably, the end of the fixing rod away from the pull plate is a hemisphere, and the arc surface of the hemisphere is slidably connected to the adjustment hole.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting up a transmission device, the amount of solder wire output from the solder wire holder is nearly precisely controlled. The motor drives the transmission roller to rotate, which, in conjunction with the transmission cylinder that abuts against the solder wire body, tightly clamps the solder wire between the two. When the motor drives the transmission roller to rotate, the friction force causes the solder wire and the transmission cylinder to rotate synchronously. By controlling the speed of the motor, the number of rotations of the transmission roller can be precisely controlled, thereby achieving quantitative adjustment of the solder wire output length. There is no need to manually pull the solder wire, avoiding the problem of excessive or insufficient output caused by uneven force during manual solder feeding. Rotating the rotating plate can drive the U-shaped frame to move through the threaded rod, adjusting the distance between the transmission cylinder and the transmission roller, ensuring that solder wires of different specifications can obtain sufficient clamping force and stable conveying effect.

[0014] In this invention, a fixing device is set to achieve a stable locking effect on the position of the wire support frame. Several adjustment holes are provided on one side of the solder wire frame body. The fixing rod can be pulled out by pulling the pull plate. At this time, the angle or position of the wire support frame can be adjusted around the rotation connection point with the solder wire frame body. Then, the fixing rod is inserted into the corresponding adjustment hole to fix it. After the fixing rod is inserted into the adjustment hole, the wire support frame can be firmly fixed in the set position by the mechanical locking structure to prevent the wire support frame from shifting due to the tension of the solder wire during the soldering process.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figures 1-5As shown, this utility model provides a technical solution: a solder wire rack with a quantitative wire output structure, comprising a solder wire rack body 1 and a placement rod 2; a handle 3 is fixedly connected to the surface of the solder wire rack body 1; a solder wire spool 5 is rotatably connected to the arc surface of the placement rod 2; a solder wire body 6 is wound around the arc surface of the solder wire spool 5; a wire support frame 4 is rotatably connected to one side of the solder wire rack body 1; the inner wall of the wire support frame 4 is slidably connected to the solder wire body 6; a transmission device 7 is provided on one side of the solder wire rack body 1; the transmission device 7 includes two L-shaped plates 701, both L-shaped plates 701 are fixedly connected to one side of the solder wire rack body 1; a motor 702 is fixedly connected to the side of the two L-shaped plates 701 that are close to each other; a transmission roller 703 is slidably inserted into the solder wire rack body 1; the transmission roller 703 and the motor 702 are connected to each other. The output end of 2 is fixedly connected, and the other end of the transmission roller 703 is rotatably connected to the solder wire frame body 1. A support plate 704 is fixedly connected to the inner wall of the solder wire frame body 1. A threaded rod 705 is threaded into the support plate 704. A rotating plate 706 is fixedly connected to one end of the threaded rod 705. A U-shaped frame 707 is rotatably connected to the end of the rotating plate 706 away from the threaded rod 705. A round rod 708 is fixedly connected to the inner wall of the U-shaped frame 707. A transmission cylinder 709 is rotatably connected to the arc surface of the round rod 708. The arc surfaces of the transmission cylinder 709 and the transmission roller 703 both abut against the solder wire body 6. By setting the transmission device 7, the near-precise control of the output amount of the solder wire frame body 1 is achieved. The motor 702 drives the transmission roller 703 to rotate, which abuts against the solder wire body 6. The connecting transmission cylinder 709 tightly clamps the solder wire between itself and the transmission roller 703. When the motor 702 drives the transmission roller 703 to rotate, the friction force causes the solder wire and the transmission cylinder 709 to rotate synchronously. By controlling the speed of the motor 702, the number of rotations of the transmission roller 703 can be precisely controlled, thereby achieving quantitative adjustment of the solder wire output length. This eliminates the need for manual pulling of the solder wire and avoids the problem of excessive or insufficient output caused by uneven force during manual solder feeding. Rotating the rotating plate 706 can move the U-shaped frame 707 through the threaded rod 705, adjusting the distance between the transmission cylinder 709 and the transmission roller 703 to ensure that solder wires of different specifications can obtain sufficient clamping force and stable conveying effect. The surface of the wire support frame 4 is equipped with a fixing device 8, which includes a fixing plate 81. The fixing plate 81 is fixedly connected to the surface of the wire support frame 4. Several adjustment holes 82 are provided on one side of the solder wire frame body 1. A fixing rod 83 is slidably inserted into the fixing plate 81. The arc surface of the fixing rod 83 is slidably connected to the adjustment hole 82. A pull plate 84 is fixedly connected to one end of the fixing rod 83. By setting the fixing device 8, the position of the wire support frame 4 is stably locked. Several adjustment holes 82 are provided on one side of the solder wire frame body 1. By pulling the pull plate 84, the fixing rod 83 can be pulled out. At this time, the angle or position of the wire support frame 4 can be adjusted around the rotation connection point with the solder wire frame body 1. Then, the fixing rod 83 is inserted into the corresponding adjustment hole 82 to fix it. After the fixing rod 83 is inserted into the adjustment hole 82, the wire support frame 4 can be firmly fixed in the set position by the mechanical locking structure.To prevent the wire support frame 4 from shifting due to the tension in the solder wire during the soldering process.

[0024] Reference Figure 2 and Figure 3 As shown in this embodiment: a guide rod 710 is slidably inserted into the support plate 704. One end of the guide rod 710 is fixedly connected to the U-shaped frame 707. By setting the guide rod 710, the movement direction of the U-shaped frame 707 can be strictly constrained, so that it only moves in a straight line along the axis of the guide rod 710. This avoids the rotation or offset that may be caused by the rotation of the threaded rod 705, ensuring that the transmission cylinder 709 always remains parallel and aligned with the transmission roller 703, ensuring a uniform and stable clamping force on the solder wire, and preventing the solder wire from being skewed or slipping due to misalignment. The arc surface of the transmission roller 703 is provided with uniformly distributed anti-slip patterns, and the anti-slip patterns are distributed in a striped pattern, which increases the transmission force. The contact roughness between the arc surface of the moving roller 703 and the solder wire body 6 significantly improves the static friction between them. Even when the motor 702 is running at low speed or conveying finer solder wire, it can effectively prevent relative sliding between the solder wire and the transmission roller 703, ensuring that the rotation of the transmission roller 703 can be accurately converted into the linear displacement of the solder wire, thus ensuring the accuracy of quantitative wire output. The arc surface of the transmission cylinder 709 is fixedly connected with a soft pad 711. The soft pad 711 is made of rubber. By setting the soft pad 711, the rubber material has good flexibility and can form a buffer when in contact with the solder wire, avoiding the metal transmission cylinder 709 from directly squeezing the solder wire, causing it to deform, scratch or break, and effectively preventing the solder wire from affecting the solder conductivity.

[0025] Reference Figure 4 and Figure 5 As shown in this embodiment: a spring 85 is fitted onto the arc surface of the fixing rod 83. The two ends of the spring 85 are fixedly connected to the fixing plate 81 and the pull plate 84, respectively. Under the force of the spring 85, when the pull plate 84 is pulled to remove the fixing rod 83, the spring 85 is further stretched and stores elastic potential energy. After the pull plate 84 is released, the spring 85 automatically retracts and pulls the fixing rod 83 back to its original position, allowing it to quickly insert into the corresponding adjustment hole 82. This eliminates the need for manual pushing of the fixing rod 83, significantly simplifying the locking process after adjusting the position of the support frame 4. To improve operational efficiency, the end of the fixing rod 83 furthest from the pull plate 84 is a hemisphere 86. The arc surface of the hemisphere 86 is slidably connected to the adjustment hole 82. When the arc surface of the hemisphere 86 contacts the adjustment hole 82, the contact area is smaller and the friction is lower compared to a flat or sharp end. When inserting or removing the fixing rod 83, the feeling of jamming with the inner wall of the adjustment hole 82 is greatly reduced. Especially when the spring 85 automatically resets and pushes the fixing rod 83 into the adjustment hole 82, jamming caused by alignment deviation can be avoided, making the operation easier.

[0026] Working principle: When the transmission device 7 is needed, the tin wire spool 5, with the tin wire body 6 wound around it, is placed on the arc surface of the placement rod 2, allowing the tin wire spool 5 to rotate freely as the tin wire is pulled out. Depending on the tin wire diameter and conveying requirements, the rotating plate 706 is rotated to adjust the threaded rod 705. The threaded rod 705 moves along the internal thread of the support plate 704, causing the U-shaped frame 707 and the transmission spool 709 to move closer to or further away from the transmission roller 703, until the rubber pad 711 on the arc surface of the transmission spool 709 and the arc surface of the transmission roller 703 form a stable and undamaged clamping force on the tin wire body 6. During this process, the guide rod 710 constrains the U-shaped frame 707 to move only in a straight line, ensuring that the transmission spool 709 and the transmission roller 703 remain level. Alignment is achieved to prevent clamping misalignment. One end of the solder wire body 6 is pulled, allowing it to pass through the inner wall of the wire support frame 4. The wire support frame 4 guides the solder wire. The motor 702 between the two L-shaped plates 701 is activated. The output of the motor 702 drives the transmission roller 703 to rotate. Because the transmission roller 703 has striped anti-slip textures on its arc surface, the friction with the solder wire body 6 is significantly increased, preventing the solder wire from slipping. Simultaneously, the rubber pad 711 of the transmission cylinder 709 provides cushioning when in contact with the solder wire, preventing the metal transmission cylinder 709 from directly squeezing the solder wire, which could cause deformation, scratches, or breakage. This effectively prevents damage to the solder wire from affecting the soldering conductivity. Furthermore, the rubber pad 711 further enhances friction, ensuring the solder wire is firmly held in place. The solder wire is clamped between the transmission roller 703 and the transmission cylinder 709. The rotation of the transmission roller 703 is converted into linear motion of the solder wire body 6 through friction. The solder wire is continuously output along the path guided by the wire support frame 4. By controlling the speed of the motor 702, the number of rotations of the transmission roller 703 can be precisely controlled, thereby precisely controlling the length of the solder wire output per unit time, achieving quantitative output. As the solder wire is continuously output, the solder wire cylinder 5 rotates synchronously along the arc surface of the placement rod 2, continuously providing solder wire for conveying. The wire support frame 4 always maintains guidance for the solder wire. In summary, by setting the transmission device 7, the near-precise control of the output of the solder wire frame body 1 is achieved. The motor 702 drives the transmission roller 703 to rotate, in conjunction with... The transmission cylinder 709, which abuts against the solder wire body 6, tightly clamps the solder wire between them. When the motor 702 drives the transmission roller 703 to rotate, the friction force will drive the solder wire and the transmission cylinder 709 to rotate synchronously. By controlling the speed of the motor 702, the number of rotations of the transmission roller 703 can be precisely controlled, thereby realizing the quantitative adjustment of the solder wire output length. There is no need to manually pull the solder wire, avoiding the problem of excessive or insufficient output caused by uneven force when manually feeding solder. The rotating plate 706 can drive the U-shaped frame 707 to move through the threaded rod 705, adjusting the distance between the transmission cylinder 709 and the transmission roller 703, ensuring that solder wires of different specifications can obtain sufficient clamping force and stable conveying effect.

[0027] Working principle: When it is necessary to adjust the angle or position of the wire support frame 4, pull the pull plate 84 away from the fixed plate 81. The pull plate 84 drives the fixed rod 83 to slide along the inner wall of the fixed plate 81, causing the hemisphere 86 at the end of the fixed rod 83 to disengage from the adjustment hole 82 of the solder wire frame body 1, thus releasing the position lock of the wire support frame 4. At the same time as pulling the pull plate 84, the spring 85 sleeved on the arc surface of the fixed rod 83 is stretched, storing elastic potential energy to prepare for subsequent reset and locking. During this process, the arc of the hemisphere 86... Due to low frictional resistance, the wire support frame 4 can be easily pulled out from the adjustment hole 82 without jamming. After the fixing rod 83 is unlocked, the angle or position of the wire support frame 4 can be freely adjusted around the rotational connection point with the solder wire support body 1. According to the diameter of the solder wire spool 5, the welding operation height, or the requirements of the solder wire conveying path, the wire support frame 4 is rotated to a suitable position to ensure that the solder wire body 6 can slide smoothly along the inner wall of the wire support frame 4, avoiding bending or tension. After determining the position of the wire support frame 4, the pull plate 84 is released, and the spring 85 releases the stored elastic potential energy, automatically... The fixed rod 83 is retracted and pulled back to the adjustment hole 82. Under the push of the spring 85, the hemisphere 86 at the end of the fixed rod 83 can automatically guide itself through contact with the edge of the adjustment hole 82, even if there is a slight alignment deviation with the target adjustment hole 82. Finally, it slides precisely into the adjustment hole 82, completing the position locking of the support frame 4. This prevents the support frame 4 from loosening due to vibration or solder wire tension during the welding process, ensuring that the support frame 4 always maintains a stable guiding state. By setting the fixing device 8, the position of the support frame 4 is firmly locked. Several adjustment holes 82 are provided on one side of the solder wire frame body 1. The fixed rod 83 can be pulled out by pulling the pull plate 84. At this time, the angle or position of the support frame 4 can be adjusted around the rotation connection point with the solder wire frame body 1. Then, the fixed rod 83 can be inserted into the corresponding adjustment hole 82 to fix it. After the fixed rod 83 is inserted into the adjustment hole 82, the support frame 4 can be firmly fixed in the set position through the mechanical locking structure to prevent the support frame 4 from shifting due to the tension of the solder wire during the welding process.
