In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0043] A first aspect of the present invention provides a tin-adding device; please refer to [link to relevant documentation]. Figure 1 The device includes a base 100, a guide wheel 200, and an adjusting member 300. The guide wheel 200 is rotatably connected to the base 100. The adjusting member 300 is rotatably connected to the base 100, and a pressing wheel 310 is provided on the adjusting member 300. A guide channel 210 for tin wire is formed between the pressing wheel 310 and the guide wheel 200. The adjusting member 300 rotates relative to the base 100, so that the pressing wheel 310 moves closer to or further away from the guide wheel 200.

[0044] Understandably, the clamping roller 310 is far from the guide roller 200 to facilitate the threading of the solder wire onto the guide channel 210. When the clamping roller 310 is close to the guide roller 200, the solder wire is clamped. When the guide roller 200 rotates, the friction force drives the solder wire to be conveyed. When the adjusting component 300 rotates relative to the base 100, the distance between the guide roller 200 and the clamping roller 310 can be adjusted, which can accommodate solder wires of different diameters and provides high flexibility.

[0045] In related technologies, the soldering process relies on the friction between the guide wheel 200 and the solder wire to transfer the solder wire. Therefore, the distance between the two guide wheels 200 is very close, making it difficult to install the solder wire between them. However, this embodiment of the invention uses the guide wheel 200 and the movable clamping wheel 310 to clamp the solder wire, supporting it while simultaneously driving its transmission. The opening and closing of the guide wheel 200 and the clamping wheel 310 not only facilitates the installation of the solder wire but also allows the guide channel 210 to be adjusted to a suitable width. If the guide channel 210 is too narrow, it increases the resistance during soldering; if it is too wide, it causes the guide wheel 200 to spin freely. Furthermore, the adjustable width of the guide channel 210 facilitates the adaptation of solder wires of different sizes.

[0046] It is understandable that when installing solder wire, the adjusting member 300 can be rotated to move the clamping wheel 310 away, facilitating the installation of the solder wire. If a guide rail is directly set on the base 100, and the adjusting member 300 is installed on the guide rail, the clamping wheel 310 can be moved closer to or away from the guide wheel 200 by the linear movement of the adjusting member 300 on the guide rail. This would require machining the guide rail on the base 100, and space needs to be reserved on the base 100 for the guide rail, resulting in a larger overall size. However, in this embodiment of the invention, the adjusting member 300 is directly hinged to the base 100, eliminating the need for excessive machining of the base 100. During the installation of solder wire, rotating the adjusting member 300 can rotate the clamping wheel 310 outside the base 100. This satisfies the requirements for solder wire transmission while also facilitating the miniaturization of the soldering device, reducing the material of the base 100, and thus lowering production costs.

[0047] Understandably, to ensure a relatively fixed width of the guide channel 210 and to maintain the pressure roller 310 in a specific position without significant external force, the adjusting component 300 can have built-in damping. While allowing the adjusting component 300 to rotate, the damping resistance maintains a fixed relative position between the pressure roller 310 and the guide roller 200, ensuring smooth wire transfer. The adjusting component 300 can be hinged to the base 100 via a pin. Friction materials such as rubber pads can be added between the pin and the shaft hole of the adjusting component 300 to improve the damping effect.

[0048] Please see Figure 1 In one embodiment, the soldering device further includes a locking assembly 400, which is adapted to fix the adjusting member 300. When the solder wire is threaded onto the guide channel 210 and the adjusting member 300 is rotated, the locking assembly 400 fixes the pressure roller 310 in a suitable position, preventing the pressure roller 310 from shifting during operation and ensuring the normal operation of the solder wire conveying.

[0049] Please see Figure 1 In one embodiment, the locking assembly 400 includes a locking rod 410, and two adjusting members 300 are provided, namely a first adjusting member 320 and a second adjusting member 330; the first end of the locking rod 410 is rotatably connected to the first adjusting member 320, and the second end of the locking rod 410 is adapted to fix or disengage from the second adjusting member 330; the locking rod 410 restricts the relative movement between the first adjusting member 320 and the second adjusting member 330 to fix the first adjusting member 320 and the second adjusting member 330.

[0050] Understandably, the first adjusting member 320 and the second adjusting member 330 are rotatably connected to the base 100, respectively. A locking rod 410 connects the first adjusting member 320 and the second adjusting member 330 to restrict their relative movement, thus maintaining the pressure roller 310 in a specific position. This ensures the appropriate width of the guide channel 210 and improves the stability of the solder feeding process. By fixing or disengaging the second adjusting member 330 through the second end of the locking rod 410, the first adjusting member 320 and the second adjusting member 330 can be fixed without requiring separate fixing of each, reducing operational steps. This makes the installation process of the solder wire simpler; the solder wire conveyed in the guide channel 210 is simultaneously subjected to the forces of the first adjusting member 320 and the second adjusting member 330. The position of the guide wheel 200 is fixed, and the first adjusting member 320 and the second adjusting member 330 are synchronously fixed by a locking rod 410. The distance between the first adjusting member 320 and the guide wheel 200 and the distance between the second adjusting member 330 and the guide wheel 200 can be adjusted synchronously, reducing the difference in the force exerted by the first adjusting member 320 and the second adjusting member 330 on the solder wire, so that the force on the solder wire is relatively uniform during the conveying process, which helps to reduce the deviation during the solder feeding process and improve the stability of the solder wire conveying process.

[0051] Understandably, the first end of the locking rod 410 is rotatably connected to the first adjusting member 320. Two connecting ears 350 can be provided on the side of the first adjusting member 320 near the locking rod 410, and the locking rod 410 is connected between the two connecting ears 350. The two connecting ears 350 can provide further support for the locking rod 410, improve the reliability of the connection, and prevent the locking rod 410 from loosening during rotation. The first adjusting member 320 is hinged to the locking rod 410 through the two connecting ears 350, which can increase the rotation angle range of the locking rod 410 and improve the rotation flexibility of the locking rod 410.

[0052] In one embodiment, a locking rod 410 may be used to fix an adjusting member 300. For example, one end of the locking rod 410 is rotatably connected to the base 100, and the other end of the locking member 410 is provided with a locking part 411. The locking part 411 is suitable for fixing or disengaging the adjusting member 300. The adjusting member 300 is hinged to the base 100, and the base 100 and the adjusting member 300 are connected by the locking rod 410, thereby restricting the movement of the adjusting member 300 and maintaining the pressure roller 310 of the adjusting member 300 in a specific position to ensure the normal operation of the solder feeding.

[0053] Please see Figure 1In one embodiment, two guide wheels 200 can be provided, with each guide wheel 200 corresponding to one of the adjusting members 300. Providing two guide wheels 200 can provide more stable support for the solder wire, preventing the solder wire from falling off and affecting the soldering work. Secondly, the two guide wheels 200 can better maintain the conveying path of the solder wire, preventing the solder wire from deviating or twisting during the conveying process, affecting the solder feeding effect, and making the conveying of the solder wire more stable.

[0054] Please see Figure 1 In one embodiment, the soldering device includes a drive component 520, the output shaft of which is fixedly connected to a guide wheel 200. The drive component 520 drives the guide wheel 200 to rotate, thereby promoting the solder feeding operation. Generally, the drive component 520 is a motor. Two drive components 520 can be provided, each driving one guide wheel 200 to rotate, achieving dual drive. If one drive component 520 fails, the other drive component 520 can maintain the operation of the device, which can improve the reliability and stability of the soldering device and reduce the occurrence of accidents. In addition, the provision of two drive components 520 can increase the overall solder feeding speed, balance the load on the two guide wheels 200, and improve work efficiency.

[0055] Please see Figure 1 In one embodiment, the soldering device further includes a third sensor 540, which is disposed between the two guide wheels 200. The third sensor 540 is located on one side of the guide channel 210 and is suitable for detecting the presence or absence of solder wire. The third sensor 540 is set up to detect the presence or absence of solder wire, thereby determining whether the soldering operation is proceeding normally. Generally, the third sensor 540 is a photoelectric sensor. If the third sensor 540 does not detect solder wire, it is determined that the solder wire has detached from the soldering device or the solder wire has been used up.

[0056] Please see Figure 1 In one embodiment, the soldering device may further include a guide block 600, through which a portion of the guide channel 210 passes and between two guide wheels 200. The guide block 600 provides further support and guidance for the solder wire, increasing stability.

[0057] Please see Figure 1In one embodiment, the guide block 600 includes at least two guide walls 610, and the guide channel 210 passes through the two guide walls 610 in sequence. The guide block 600 is fixedly mounted on the base 100, and the guide walls 610 support the solder wire. The two guide walls 610 improve the stability of the solder wire during movement and further enhance the guiding effect. A detection space 620 is formed between the two guide walls 610, and the probe of the third sensor 540 faces the detection space 620. The two guide walls 610 confine part of the solder wire within the detection space 620, which facilitates the third sensor 540 in detecting the solder wire located in the guide channel 210 and improves the accuracy of the detection. Of course, guide holes can also be directly opened on the guide block 600; the third sensor 540 can also be located at one end of the guide block 600.

[0058] Of course, in other embodiments, a guide wheel 200 can also be provided, and two adjusting members 300 can be pressed against different positions of the guide wheel 200, so that the solder wire is conveyed in contact with the surface of the guide wheel 200, and the surface of the guide wheel 200 can provide support for the solder wire.

[0059] Please see Figures 1 to 2 In one embodiment, the second adjusting member 330 is provided with a mating notch 340 on the side facing the locking rod 410, which mates with the locking part 411, and the second end of the locking rod 410 is adapted to be fixed or disengaged from the mating notch 340.

[0060] It is understandable that providing a mating notch 340 on the second adjusting member 330 facilitates the mating of the locking rod 410 and the second adjusting member 330, making operation simpler and more convenient. During the rotation of the locking rod 410, the mating notch 340 can approach and mate with the locking rod 410 from the circumferential direction. To prevent the second adjusting member 330 from falling off, the length of the second end of the locking rod 410 can be appropriately extended. At the same time, the extended portion of the second end of the locking rod 410 can also serve as a handheld position during operation. If the second adjusting member 330 mates directly with the locking rod 410 from the end direction, the longer the locking rod 410, the more difficult the mating becomes. However, in this embodiment of the invention, the second adjusting member 330 mates with the locking rod 410 from the circumferential direction, and the extension of the second end of the locking rod 410 does not affect the mating between the locking rod 410 and the second adjusting member 330.

[0061] To achieve standardization of parts and reduce production costs and inventory pressure, the first adjusting member 320 and the second adjusting member 330 can adopt the same structure. For example, a mating notch 340 can be formed between the two connecting ears 350.

[0062] Please see Figure 1In one embodiment, the locking assembly 400 further includes a spring element 420, which is sleeved on the locking rod 410 and abuts against the second adjusting member 330. The elasticity of the spring element 420 is suitable for adjusting the distance between the first adjusting member 320 and the second adjusting member 330. Using tension, the pressure wheel 310 presses tightly against the guide wheel 200 to achieve clamping and transmission of the solder wire. Because the spring element 420 is elastic, the distance between the first adjusting member 320 and the second adjusting member 330 can fluctuate within a certain range. Therefore, the guide channel 210 can accommodate solder wires within a certain diameter range, providing flexibility. When adjusting solder wires of different diameters, there is no need to change different soldering devices, making it widely adaptable. Generally, the spring element 420 is a spring.

[0063] Please see Figure 1 In one embodiment, the pressure roller 310 of the first adjusting member 320 is disposed on the side close to the second adjusting member 330, and the pressure roller 310 of the second adjusting member 330 is disposed on the side close to the first adjusting member 320.

[0064] It is understandable that the clamping rollers 310 of the first adjusting member 320 and the second adjusting member 330 are both located on opposite sides. With this arrangement, when the distance between the first adjusting member 320 and the second adjusting member 330 is shortened, the clamping roller 310 of the first adjusting member 320 presses tightly against the first guide wheel 200, and the clamping roller 310 of the second adjusting member 330 presses tightly against the second guide wheel 200. This allows for synchronous adjustment of the forces exerted by the first adjusting member 320 and the second adjusting member 330 on the guide wheel 200. For example, by fixing the elastic member 420 to the second end of the locking rod 410, the elastic force of the elastic member 420 causes the second adjusting member 330 to move closer to the first adjusting member 320, thereby causing both clamping rollers 310 to simultaneously press against the guide wheel 200. The elastic element 420 can be fixed to the second end of the locking rod 410 by welding or other means, or a limiting block can be set at the second end of the locking rod 410, with one end of the elastic element 420 abutting against the limiting block.

[0065] In other embodiments, the pressing wheel 310 of the first adjusting member 320 is located on the side away from the second adjusting member 330, and the pressing wheel 310 of the second adjusting member 330 is located on the side away from the first adjusting member 320. The elastic member 420 can be located between the first adjusting member 320 and the second adjusting member 330. Utilizing the elastic force of the elastic member 420, the first adjusting member 320 and the second adjusting member 330 are moved away from each other. At this time, the pressing wheels 310 of the first adjusting member 320 and the second adjusting member 330 simultaneously press against the guide wheel 200, achieving synchronous action of the two adjusting members on the guide wheel 200.

[0066] Please see Figure 1In one embodiment, the locking assembly 400 further includes a sleeve 430 and an abutment block 440. The sleeve 430 is sleeved on the second end of the locking rod 410. On one hand, the sleeve 430 can serve as a handle for the locking rod 410. On the other hand, the elastic element 420 can be disposed inside the sleeve 430, which protects the elastic element 420 and prevents it from scratching the operator. It is understood that the elastic element 420 extends partially out of the sleeve 430 to facilitate the operation of the elastic element 420. 0 interacts with the second adjusting member 330; the end of the elastic member 420 away from the sleeve 430 is connected to the abutment block 440, and the abutment block 440 is located between the second adjusting member 330 and the sleeve 430. The elastic member 420 abuts against the second adjusting member 330 through the abutment block 440, which can increase the force-bearing area of ​​the second adjusting member 330. The elastic member 420 can also be compressed by pressing the abutment block 440, which facilitates operation and avoids the operator being scratched by the elastic member 420 by directly pressing the elastic member 420 during operation.

[0067] Please see Figures 1 to 2 In one embodiment, the adjusting member 300 is provided with a fixing part 360 on the side away from the locking rod 410. One end of the fixing part 360 is hinged to the base 100, and the other end is rotatably connected to the pressure wheel 310.

[0068] Understandably, one end of the fixing part 360 is hinged to the base 100, enabling relative rotation between the adjusting member 300 and the base 100. The other end of the fixing part 360 is rotatably connected to the pressure wheel 310, which can drive the pressure wheel 310 away from or closer to the guide wheel 200. Since the pressure wheel 310 is located at the end of the fixing part 360, a large displacement of the pressure wheel 310 can be achieved by rotating the fixing part 360 within a small range of angles, which is beneficial for the installation of solder wire.

[0069] Please see Figure 1 and Figure 3 In one embodiment, the soldering device includes a spool 820 and a counting component 700, the spool 820 being adapted to hold solder wire; the counting component 700 being adapted to count the number of rotations of the guide wheel 200 or the spool 820.

[0070] The rotation of the guide wheel 200 drives the transmission of the solder wire, while the winding shaft 820 rolls to realize the transmission of the solder wire; the counting component 700 calculates the number of rotations of the guide wheel 200 or the winding shaft 820, and then calculates the length of the solder wire to be used.

[0071] Understandably, the guide wheel 200 drives the solder wire transmission, and the solder wire is wound on the coil shaft 820. When the solder wire is conveyed, the coil shaft 820 rotates, and the number of turns of the solder wire on the coil shaft 820 decreases. The length of solder wire used can be calculated according to the formula based on the number of rotations of the coil shaft 820 and the diameter of the coil shaft 820.

[0072] Alternatively, the length of solder wire used can be calculated using a formula based on the number of rotations of the guide wheel 200 and its diameter. The solder wire is wound on the coil 820, forming multiple layers of solder coils from the inside out. The diameter of the outermost solder coil is larger than that of the innermost coil. Comparatively, using the diameter of the guide wheel 200 is more stable, and calculating the length of solder wire used using the number of rotations of the guide wheel 200 yields more accurate data.

[0073] Please see Figure 1 In one embodiment, the counting component 700 includes a trigger 710 and a first sensor 720. The trigger 710 is fixedly connected to the guide wheel 200. The trigger 710 includes a trigger part 711 located on the periphery of the guide wheel 200. The first sensor 720 is disposed on one side of the guide wheel 200. The first sensor 720 is adapted to detect the position state of the trigger part 711.

[0074] Understandably, the trigger 710 rotates synchronously with the guide wheel 200, and the trigger part 711 is located on the periphery of the guide wheel 200. The first sensor 720 detects the position state of the trigger part 711, calculates the number of rotations of the trigger 710, and then determines the number of rotations of the guide wheel 200. The length of the solder wire passing through the guide wheel 200 is calculated using the diameter of the guide wheel 200 and the number of rotations.

[0075] Generally, the first sensor 720 is a photoelectric sensor. Photoelectric sensors have the characteristics of high detection accuracy and fast response speed, which helps to improve the accuracy of counting and reduce measurement errors. During the detection process, the photoelectric sensor does not need to be in direct contact with the trigger 710, avoiding wear or damage to the trigger 710 caused by physical contact and reducing the impact on the solder wire conveying operation. The first sensor 720 is set on the base 100. When the trigger 710 rotates, the trigger part 711 passes through the probe of the third sensor 540. The third sensor 540 detects the trigger part 711 and thus calculates the number of rotations of the guide wheel 200.

[0076] It is understood that the trigger 710 can be a column coaxially arranged with the guide wheel 200 or it can be an annular shape; the embodiments of the present invention may include fixing screws to connect the trigger 710 and the guide wheel 200; the trigger 710 and the guide wheel 200 can be integrally formed, which is convenient for processing and installation.

[0077] In one embodiment, the trigger 710 is provided with at least two trigger portions 711, and a detection gap is provided between two adjacent trigger portions 711. The detection gap is suitable for separating two adjacent trigger portions 711, so that different trigger portions 711 can trigger the third sensor respectively.

[0078] Please see Figure 1 In one embodiment, the trigger portions 711 are evenly distributed around the periphery of the trigger member 710, which can improve the detection accuracy. For example, two trigger portions 711 are symmetrically arranged on opposite sides of the trigger member 710. If the third sensor detects two trigger portions 711, the guide wheel 200 rotates one revolution; if the third sensor detects three trigger portions 711, the guide wheel 200 rotates one and a half revolutions, and so on. Similarly, three, four, or five trigger portions 711 can be evenly arranged around the periphery of the trigger member 710 to improve the detection accuracy.

[0079] In one embodiment, the trigger 710 is a gear, the trigger part 711 is the tooth of the gear, and the trigger 710 and the guide wheel 200 are coaxially arranged.

[0080] Understandably, when the gear rotates, the third sensor 540 detects the passage of the gear teeth to calculate the number of rotations of the guide wheel 200. Using the gear directly as the trigger element 710 reduces procurement costs, eliminates the need for separate design and manufacturing of the trigger element 710, and facilitates later maintenance and replacement. The output shaft of the drive element 520 connects the guide wheel 200 and the trigger element 710, directly driving the synchronous rotation of the guide wheel 200 and the trigger element 710. Simultaneously, the output shaft of the drive element 520 can also serve as a connector between the guide wheel 200 and the trigger element 710, ensuring their relative fixation.

[0081] Please see Figure 1 In one embodiment, the trigger 710 is sheet-shaped. The sheet-shaped structure can minimize the space occupied by the trigger 710, making the overall structure of the soldering device more compact. Secondly, the sheet-shaped design can greatly reduce the material used in the trigger 710, reducing production costs. Because the trigger 710 is thin and light, it is easy for the trigger 710 to fit against the guide wheel 200, reducing the relative movement between the guide wheel 200 and the trigger 710 and improving the accuracy of detection. The trigger 710 can be a metal sheet. The metal sheet meets the requirements of lightweight design while having a certain rigidity to prevent the trigger 710 from deforming under force during rotation.

[0082] Please see Figure 1In one embodiment, the trigger part 711 is rod-shaped. Compared with other shapes, the rod-shaped trigger part 711 is narrower, which is conducive to forming a detection gap between two adjacent trigger parts 711 to improve accuracy. In addition, the rod-shaped trigger part 711 is relatively slender, and the free end of the trigger part 711 extends outward and corresponds to the probe of the third sensor 540, so as to avoid other parts such as the guide wheel 200 from affecting the detection work of the third sensor 540.

[0083] Please see Figure 3 In one embodiment, the counting component 700 includes an encoder 730 and a second sensor 740. The encoder 730 is mounted on the guide wheel 200 or the winding shaft 820, and the second sensor 740 is adapted to detect the rotation state of the encoder 730, thereby determining the number of rotations of the guide wheel 200 or the winding shaft 820, which facilitates the calculation of the length of the solder wire used.

[0084] Generally, the tin-adding device also includes a base 510, a roll 820 rotatably connected to the base 510, an encoder 730 disposed at the end of the roll 820, and a second sensor 740 disposed on the inner wall of the base 510 and corresponding to the encoder 730, so as to facilitate the detection of the number of rotations of the roll 820.

[0085] The encoder 730 can also be set on the guide wheel 200, and the second sensor 740 is set on the base 100 to calculate the length of the solder wire used by detecting the number of rotations of the guide wheel 200.

[0086] The encoder 730 is a magnetic disk or magnet. Compared to the gear encoder 730, the magnetic encoder 730 offers higher resolution and more accurate detection of rotational position and speed. It is a non-contact sensor, detecting rotational position and speed through a magnetic field without direct contact with rotating parts, making it better suited for high-speed rotation and more resistant to external vibrations and temperature changes. The second sensor 740 detects changes in the magnetic field of the encoder 730 to determine its rotational speed and position, and then calculates the number of rotations of the guide wheel 200 or the winding shaft 820. Typically, the second sensor 740 is a Hall effect sensor.

[0087] Please see Figure 4 In one embodiment, the tin-adding device includes a turntable 810 and a fourth sensor 830. The turntable 810 is disposed on the substrate 510 and rotates relative to the substrate 510. The fourth sensor 830 is disposed between the substrate 510 and the turntable 810 and is adapted to detect the weight of the turntable 810.

[0088] Solder wire can be placed directly on turntable 810. As the solder wire is used, the weight of turntable 810 changes accordingly. Based on the weight data of turntable 810 detected by the fourth sensor 830, the usage status of the solder wire is determined to detect the remaining amount of solder wire. Solder wire is generally in a roll. Turntable 810 can rotate flexibly as the solder wire is used to avoid the solder wire from twisting during use and affecting the transmission of the solder wire.

[0089] It is understood that the turntable 810 is disposed on the base 510, and the fourth sensor 830 is disposed between the base 510 and the turntable 810, so that the fourth sensor 830 can obtain the weight of the turntable 810; the fourth sensor 830 is generally a load cell, which is a device that converts a mass signal into a measurable electrical signal output. In other embodiments, the fourth sensor 830 may also be a pressure sensor.

[0090] Please see Figure 5 In one embodiment, the substrate 510 has a movable groove 512 inside; the soldering device also includes a storage component 910, an elastic component 930 and a trigger sensor 920. The storage component 910 has a solder wire trough 911 inside, and the storage component 910 is movably disposed in the movable groove 512; the elastic component 930 connects the bottom of the storage component 910 and the bottom of the movable groove 512; the trigger sensor 920 is disposed on the side wall of the movable groove 512.

[0091] Understandably, when there is sufficient solder wire remaining, the elastic element 930 is compressed. During the use of the solder wire, as the amount of solder wire decreases, the storage element 910 moves upward under the elastic force of the elastic element 930. When the amount of solder wire in the trough 911 falls below a preset level, the elastic force of the elastic element 930 drives the storage element 910 to move to the set position, thus triggering the trigger sensor 920. Through the elastic element 930 and the trigger sensor 920, the remaining amount of solder wire can be detected in real time, allowing for timely replenishment. The trigger sensor 920 can be a photoelectric switch.

[0092] A second aspect of the present invention also provides a wave soldering machine, including a solder pot and a solder feeding device, the solder feeding device being adapted to supply solder wire to the solder pot.
