[0044] See also Figure 5The first embodiment of the present invention provides a tin material device, comprising a base 510, a storage member 910, an elastic member 950, and a trigger sensor 920. The base 510 has a movable groove 512 therein; the storage member 910 has a tin material trough 911 therein, and the storage member 910 is movably disposed within the movable groove 512; the elastic member 950 connects the bottom of the storage member 910 to the bottom of the movable groove 512; and the trigger sensor 920 is disposed on a sidewall of the movable groove 512. When the tin material in the trough 911 falls below a preset level, the elastic force of the elastic member 950 drives the storage member 910 to move to a set position, thereby triggering the trigger sensor 920.

[0045] It is understood that when the remaining amount of tin is sufficient, the elastic member 950 is compressed. During the use of the tin, as the amount of tin decreases, the storage member 910 moves upward due to the elastic force of the elastic member 950. When the amount of tin in the trough 911 falls below a preset amount, the elastic force of the elastic member 950 drives the storage member 910 to move to a set position, thereby triggering the trigger sensor 920. The elastic member 950 and the trigger sensor 920 can monitor the remaining amount of tin so that tin can be added in a timely manner.

[0046] It is understood that the elastic member 950 connects the bottom of the storage member 910 and the bottom of the movable groove 512, which is conducive to hiding the elastic member 420 and preventing the elastic member 420 from being exposed. The elastic member 420 bears the weight of the storage member 910, increases or decreases the tin material inside the storage member 910, and the elastic member 420 produces different degrees of deformation, allowing the storage member 910 to move within the movable groove 512. By triggering the sensor 920 to monitor the position of the storage member 910, the remaining tin material inside the storage member 910 is detected. The gravity of the storage member 910 can compress the elastic member 420, and the elastic force of the elastic member 420 can drive the storage member 910 to move as the remaining tin material changes. In this process, no other power source is required, saving energy. Generally, the elastic member 420 is a spring.

[0047] Generally, the trigger sensor 920 may be a photoelectric switch, which may be electrically connected to an alarm. When the photoelectric switch is triggered, the alarm may sound an alarm in time to notify the staff to add tin. The alarm may be a buzzer.

[0048] See also Figure 5 In one embodiment, a trigger groove 5121 is provided on the inner wall of the movable groove 512, and the trigger sensor 920 is provided in the trigger groove 5121; a trigger protrusion 912 is provided on the outer wall of the storage member 910, and the trigger protrusion 912 extends into the trigger groove 5121, and the trigger protrusion 912 is suitable for triggering the trigger sensor 920.

[0049] It can be understood that the trigger groove 5121 can provide a physical barrier for the trigger sensor 920 to prevent the trigger sensor 920 from being accidentally triggered or damaged; the trigger groove 5121 provides a storage space for the trigger sensor 920. If the trigger sensor 920 is directly set on the inner wall of the movable groove 512, it is not easy to fix the trigger sensor 920 due to the relatively smooth inner wall of the movable groove 512 and the lack of a supporting structure, which can easily cause the trigger sensor 920 to shift and lead to inaccurate detection data; furthermore, the inner wall of the movable groove 512 may contact the outer wall of the storage part 910, and the storage part 910 may easily scratch the trigger sensor 920, causing the trigger sensor 920 to fall off.

[0050] It is understood that as the storage element 910 moves within the movable groove 512, the trigger protrusion 912 is driven to move within the trigger groove 5121; when the storage element 910 moves to the set position, the trigger protrusion 912 triggers the trigger sensor 920. The trigger groove 5121 provides a space for the trigger protrusion 912 to prevent the trigger protrusion 912 from colliding with the inner wall of the movable groove 512 during the movement of the storage element 910; the trigger protrusion 912 extends into the trigger groove 5121, which can reduce the distance between the outer wall of the storage element 910 and the inner wall of the movable groove 512, facilitating the movement of the storage element 910 within the movable groove 512. The trigger groove 5121 acts as a limiter for the trigger protrusion 912, thereby limiting the range of movement of the storage element 910.

[0051] See also Figure 5 In one embodiment, the trigger sensor 920 is disposed on a side of the trigger slot 5121 away from the elastic member 950 .

[0052] It is understood that as the tin in storage element 910 is consumed, storage element 910 rises due to the elastic force of elastic member 950. When the remaining amount of tin in storage element 910 falls below a predetermined value, trigger protrusion 912 triggers trigger sensor 920. Due to the limiting effect of trigger groove 5121, trigger protrusion 912 stops moving when it moves to the side of trigger groove 5121 away from elastic member 950. At this point, trigger sensor 920 and trigger protrusion 912 are in relative positions, which facilitates the action of trigger protrusion 912 on trigger sensor 920, improving detection accuracy and reducing errors.

[0053] See also Figure 5In one embodiment, a limiter 513 is provided on the inner wall of the movable groove 512 to limit the range of movement of the storage element 910. It is understood that the elastic force of the elastic member 950 drives the storage element 910 to move within the movable groove 512. If the elastic force of the elastic member 950 is too strong, the storage element 910, which has a low residual amount, may be moved outside the sensing range of the trigger sensor 920, affecting detection accuracy. When the residual amount of tin in the storage element 910 is low, the elastic member 950 causes the storage element 910 to continuously rise until the elastic member 950 is fully extended. However, after repeated use, the elastic coefficient of the elastic member 950 changes, resulting in uncertainty in the movement distance of the storage element 910 after the tin is exhausted. Therefore, the limiter 513 provided in this embodiment of the present invention confines the storage element 910 to a specific range, facilitating the determination of the storage element 910's position and reducing the risk of accidents. The limiter 513 can be secured to the inner wall of the movable groove 512 by means such as threaded connections.

[0054] When the storage component 910 moves to the set position, the storage component 910 abuts against the limiting portion 513. That is, when the internal tin material remaining amount of the storage component 910 is insufficient, the limiting portion 513 limits the storage component 910 to the set position, which is conducive to the triggering protrusion 912 acting on the trigger sensor 920, thereby improving the accuracy of the detection.

[0055] In one embodiment, the inner wall of the trigger groove 5121 is arc-shaped, which facilitates cleaning and reduces dust accumulation in dead corners; the trigger protrusion 912 can be rod-shaped to facilitate insertion into the interior of the trigger groove 5121.

[0056] See also Figure 5 In one embodiment, a distance sensor 930 is provided at the bottom of the storage element 910 , and the distance sensor 930 is adapted to detect the distance between the storage element 910 and the bottom of the movable groove 512 .

[0057] Distance sensor 930 detects the distance between storage element 910 and the bottom of movable groove 512. Specifically, distance sensor 930 detects the distance between the bottom of storage element 910 and the bottom of movable groove 512, thereby confirming the position of storage element 910. If storage element 910 moves to a set position, it is determined that the remaining tin material inside storage element 910 is insufficient. Distance sensor 930 enables contactless detection of the remaining tin material. Distance sensor 930 is located at the bottom of storage element 910 to avoid obstructing the movement of the movable element.

[0058] See also Figure 5In one embodiment, in order to improve the stability of the elastic member 950, the tin material device also includes a guide member 940, which is arranged at the bottom of the movable groove 512 and is mutually sleeved with the elastic member 950, so that the elastic member 950 can maintain linear motion when subjected to force, preventing the elastic member 950 from deflecting or twisting; generally, the guide member 940 can be a column inserted into the elastic member 950, or it can be a sleeve sleeved on the outside of the elastic member 950. The embodiment of the utility model does not specifically limit the specific structure of the guide member 940.

[0059] See also Figure 5 In one embodiment, in order to disperse the force and further improve the stability of the elastic member 950, at least two elastic members 950 are provided, and the elastic members 950 correspond to the guide members 940 one by one; providing multiple guide members 940 can provide more support points to help the elastic member 950 remain stable during movement; if one of the guide members 940 fails or is damaged, the other guide members 940 can continue to provide support for the elastic member 950, thereby reducing the occurrence of tin material device failure.

[0060] Due to the relative movement between the storage member 910 and the movable groove 512 , a negative pressure state or a high pressure state is easily formed between the bottom of the storage member 910 and the bottom of the movable groove 512 , which affects the detection of the remaining tin material.

[0061] See also Figure 5 In one embodiment, the bottom of the movable tank 512 is provided with air holes 5122. These holes allow air to pass through, increasing air flow between the interior and exterior of the movable tank 512. This prevents the formation of a vacuum or excessive pressure between the bottom of the storage element 910 and the bottom of the movable tank 512, thereby reducing the impact on test results. The air holes 5122 promote air flow, helping to reduce humidity, prevent moisture accumulation, and reduce the possibility of corrosion and mold growth.

[0062] Generally, the tin material can be a tin wire, which is convenient for transporting the tin material to the tin furnace.

[0063] In one embodiment, see Figure 1 The tin material device also includes a base 100, a coil shaft 820, a guide wheel 200 and a counting component 700. The coil shaft 820 is suitable for placing the tin wire; the guide wheel 200 is rotatably connected to the base 100, and one side of the guide wheel 200 forms a guide channel 210 for the tin wire; the counting component 700 is suitable for counting the number of rotations of the guide wheel 200 or the coil shaft 820.

[0064] The rotation of the guide wheel 200 drives the transmission of the tin wire, and the coil shaft 820 rolls to realize the transmission of the tin wire; the counting component 700 calculates the used length of the tin wire by counting the number of rotations of the guide wheel 200 or the coil shaft 820.

[0065] It can be understood that the guide wheel 200 is used to drive the tin wire transmission, and the tin wire is wound on the coil shaft 820. When the tin wire is transmitted, the coil shaft 820 rotates, and the number of turns of the tin wire on the coil shaft 820 decreases. The length of the tin wire used can be obtained by calculating the number of turns of the coil shaft 820 and multiplying it by the diameter of the coil shaft 820.

[0066] Alternatively, the length of the solder wire used can be calculated by multiplying the number of rotations of the guide wheel 200 by its diameter. The solder wire is wound around the coil shaft 820, forming multiple layers of solder coils from the inside out. The outer coils have a larger diameter than the inner coils. By comparison, using the diameter of the guide wheel 200 is more stable, and calculating the length of the solder wire used based on the number of rotations of the guide wheel 200 provides more accurate data.

[0067] In one embodiment, see Figure 1 The tin material device includes an adjusting member 300, which is rotatably connected to the base 100 and is provided with a pressure wheel 310; a guide channel 210 for the tin wire is formed between the pressure wheel 310 and the guide wheel 200; the adjusting member 300 rotates relative to the base 100 so that the pressure wheel 310 approaches or moves away from the guide wheel 200.

[0068] It can be understood that the pinch wheel 310 is away from the guide wheel 200, which makes it convenient for the tin wire to pass through the guide channel 210. When the pinch wheel 310 is close to the guide wheel 200, the tin wire can be pinched; the guide wheel 200 rotates and uses friction to drive the transmission of the tin wire; the adjustment member 300 rotates relative to the base 100 to adjust the distance between the guide wheel 200 and the pinch wheel 310, which can be used for tin wires of different diameters and has high flexibility.

[0069] In the related art, since the friction between the guide wheel 200 and the tin wire is required to achieve the effect of conveying the tin wire during the welding process, the distance between the two guide wheels 200 is very close, and the tin wire is difficult to install between the two guide wheels 200. However, the embodiment of the utility model clamps the tin wire through the guide wheel 200 and the movable pressure wheel 310, which can drive the transmission of the tin wire while supporting the tin wire; the separation and combination of the guide wheel 200 and the pressure wheel 310 not only facilitates the installation of the tin wire, but also allows the guide channel 210 to be adjusted to an appropriate width. If the width of the guide channel 210 is too small, it will increase the resistance of the tinning process. If the width of the guide channel 210 is too large, it will cause the guide wheel 200 to idle; in addition, the width of the guide channel 210 is adjustable, which is conducive to adapting to tin wires of different sizes.

[0070] It is understandable that when installing the tin wire, the adjusting member 300 can be rotated to move the pinch wheel 310 away, facilitating the installation of the tin wire. If a guide rail is directly provided on the base 100 and the adjusting member 300 is installed on the guide rail, the pinch wheel 310 is moved closer to or away from the guide wheel 200 by the linear motion of the adjusting member 300 on the guide rail. This requires machining the guide rail on the base 100, and space for the guide rail needs to be reserved on the base 100, resulting in a larger overall volume. In the embodiment of the present utility model, 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 the tin wire, the adjusting member 300 can be rotated to move the pinch wheel 310 outside the base 100. This not only meets the tin wire transmission requirements but also facilitates the miniaturization of the tin material device, reduces the material content of the base 100, and thus reduces production costs.

[0071] It is understood that to ensure a relatively fixed width of the guide channel 210 and maintain the pinch wheel 310 in a specific position in the absence of significant external force, the adjustment member 300 can have inherent damping. While the adjustment member 300 rotates, the damping resistance maintains the relative position between the pinch wheel 310 and the guide wheel 200, thereby ensuring smooth solder wire transfer. The adjustment member 300 can be hinged to the base 100 via a pin, and friction material such as a rubber gasket can be added between the pin and the shaft hole of the adjustment member 300 to enhance the damping effect.

[0072] See also Figure 1 In one embodiment, the soldering device further includes a locking assembly 400, which is adapted to secure the adjusting member 300. The solder wire is passed through the guide channel 210, and the adjusting member 300 is rotated. The locking assembly 400 secures the pinch wheel 310 in place, preventing displacement during operation and ensuring proper solder wire delivery.

[0073] See also Figure 1 In one embodiment, the locking assembly 400 includes a locking rod 410, and the adjusting member 300 is provided with two, 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 suitable for fixing or disengaging from the second adjusting member 330; the relative movement between the first adjusting member 320 and the second adjusting member 330 is limited by the locking rod 410 to fix the first adjusting member 320 and the second adjusting member 330.

[0074] It can be understood that the first adjusting member 320 and the second adjusting member 330 are respectively rotatably connected to the base 100, and the first adjusting member 320 and the second adjusting member 330 are connected by the locking rod 410 to limit the relative movement between the first adjusting member 320 and the second adjusting member 330, so that the pinch wheel 310 is maintained in a specific position, thereby ensuring the appropriate width of the guide channel 210 and improving the stability of the tin feeding process; the first adjusting member 320 and the second adjusting member 330 can be fixed or detached by the second end of the locking rod 410, and the first adjusting member 320 and the second adjusting member 330 can be fixed, without the need to fix the first adjusting member 320 and the second adjusting member 330 separately, thereby reducing the operation process. This makes the installation process of the tin wire easier; the tin wire transmitted in the guide channel 210 is simultaneously subjected to the force 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 through a locking rod 410, and 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 synchronously adjusted, narrowing the difference in the force of the first adjusting member 320 and the second adjusting member 330 on the tin wire, so that the force on the tin wire during the transmission process is relatively uniform, which is beneficial to reducing the deviation in the tin feeding process and improving the stability of the tin wire transmission process.

[0075] It can be understood that the first end of the locking rod 410 is rotatably connected to the first adjusting member 320, and two connecting ears 350 can be set on the side of the first adjusting member 320 close to the locking rod 410, and the locking rod 410 is connected between the two connecting ears 350; the two connecting ears 350 can further support the locking rod 410, improve the reliability of the connection, and prevent the locking rod 410 from loosening during the rotation process; 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 flexibility of the rotation of the locking rod 410.

[0076] In one embodiment, a locking rod 410 may be corresponding to a fixed 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 portion 411, which is suitable for fixing or disengaging the adjusting member 300; the adjusting member 300 is hinged on the base 100, and the base 100 and the adjusting member 300 are connected by the locking rod 410, thereby limiting the movement of the adjusting member 300, and then maintaining the clamping wheel 310 of the adjusting member 300 in a specific position to ensure the normal progress of the tin feeding work.

[0077] See also Figure 1In one embodiment, two guide wheels 200 can be provided, and the guide wheels 200 correspond to the adjusting members 300 one by one. Setting two guide wheels 200 can provide more stable support for the tin wire, preventing the tin wire from falling off and affecting the welding work. Secondly, the two guide wheels 200 can better maintain the transmission path of the tin wire, preventing the tin wire from being offset or twisted during the transmission process, affecting the tin feeding effect, and making the transmission of the tin wire more stable.

[0078] See also Figure 1 In one embodiment, the tin material device includes a driving member 520, and the output shaft of the driving member 520 is fixedly connected to the guide wheel 200; the driving member 520 drives the guide wheel 200 to rotate, thereby promoting the tin feeding work; generally, the driving member 520 is a motor; two driving members 520 can be provided, and the two driving members 520 respectively drive the two guide wheels 200 to rotate to achieve dual drive. If one of the driving members 520 fails, the operation of the device can be maintained by relying on the other driving member 520, which can improve the reliability and stability of the tin material device and reduce the occurrence of accidents; in addition, the setting of two driving members 520 can increase the overall tin feeding speed, balance the load of the two guide wheels 200, and improve work efficiency.

[0079] See also Figure 1 In one embodiment, the tin material 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 of tin wire. The third sensor 540 is disposed to detect the presence of tin wire by detecting the presence of tin wire, thereby determining whether the tin feeding operation is proceeding normally. Generally, the third sensor 540 is a photoelectric sensor. If the third sensor 540 does not detect the tin wire, it is determined that the tin wire is out of the tin material device or the tin wire is exhausted.

[0080] See also Figure 1 In one embodiment, the tin material device may further include a guide block 600. The guide channel 210 partially passes through the guide block 600 and the guide block 600 is located between the two guide wheels 200. The guide block 600 further supports and guides the tin wire to increase stability.

[0081] See also 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 tin wire. The provision of two guide walls 610 can improve the stability of the tin wire during movement, further enhancing the guiding effect. A detection space 620 is formed between the two guide walls 610, and the probe of the third sensor 540 is directed toward the detection space 620. The two guide walls 610 confine a portion of the tin wire within the detection space 620, which facilitates the third sensor 540 to detect the tin wire located in the guide channel 210, thereby improving the accuracy of the detection. Of course, a guide hole can also be directly opened in the guide block 600; the third sensor 540 can also be set at one end of the guide block 600.

[0082] Of course, in other embodiments, a guide wheel 200 may also be provided, and two adjusting members 300 are respectively pressed on different positions of the guide wheel 200 so that the tin wire adheres to the surface of the guide wheel 200 for transmission, and the surface of the guide wheel 200 can provide support for the tin wire.

[0083] See also Figures 1 to 2 In one embodiment, the second adjusting member 330 is provided with a matching notch 340 matching with the locking portion 411 on a side facing the locking rod 410 , and the second end of the locking rod 410 is suitable for fixing or disengaging from the matching notch 340 .

[0084] The cam 330 is adapted to engage the second adjusting member 330 with the engagement member 410, thereby facilitating engagement of the cam 330 with the second adjusting member 330.

[0085] In order to achieve standardization of parts and reduce production costs and inventory pressure, the first adjusting member 320 and the second adjusting member 330 may adopt the same structure. For example, the matching notch 340 may be formed between the two connecting ears 350 .

[0086] See also Figure 1In one embodiment, the locking assembly 400 further includes an elastic member 420, which is sleeved on the locking rod 410 and abuts against the second adjusting member 330. The elastic force of the elastic member 420 is suitable for adjusting the distance between the first adjusting member 320 and the second adjusting member 330. The tension is used to cause the pressure wheel 310 to press the guide wheel 200, thereby achieving the clamping and transmission effect on the tin wire. Due to the elasticity of the elastic member 420, 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 tin wires within a certain diameter range, which is flexible. When adjusting tin wires of different diameters, there is no need to replace different tin material devices, which has a wide range of adaptability. Generally, the elastic member 420 is a spring.

[0087] See also Figure 1 In one embodiment, the pressure wheel 310 of the first adjusting member 320 is arranged on a side close to the second adjusting member 330 , and the pressure wheel 310 of the second adjusting member 330 is arranged on a side close to the first adjusting member 320 .

[0088] It is understood that the pressure roller 310 of the first adjusting member 320 and the pressure roller 310 of the second adjusting member 330 are both arranged on opposite sides. With this arrangement, when the distance between the first adjusting member 320 and the second adjusting member 330 is shortened, the pressure roller 310 of the first adjusting member 320 presses the first guide wheel 200, and the pressure roller 310 of the second adjusting member 330 presses the second guide wheel 200, thereby achieving 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, the elastic member 420 is fixed to the second end of the locking rod 410, and the elastic force of the elastic member 420 is used to move the second adjusting member 330 closer to the first adjusting member 320, thereby causing the two pressure rollers 310 to press the guide wheel 200 simultaneously. The elastic member 420 can be fixed to the second end of the locking rod 410 by welding or the like, or a limit block can be provided at the second end of the locking rod 410 , with one end of the elastic member 420 abutting against the limit block.

[0089] In other embodiments, the pressure wheel 310 of the first adjusting member 320 is disposed on a side away from the second adjusting member 330, and the pressure wheel 310 of the second adjusting member 330 is disposed on a side away from the first adjusting member 320. The elastic member 420 may be disposed between the first adjusting member 320 and the second adjusting member 330. The elastic force of the elastic member 420 is utilized to move the first adjusting member 320 and the second adjusting member 330 away from each other. At this time, the pressure wheel 310 of the first adjusting member 320 and the pressure wheel 310 of the second adjusting member 330 simultaneously press the guide wheel 200, thereby achieving a synchronous action of the two adjusting members on the guide wheel 200.

[0090] See also 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 the one hand, the sleeve 430 can serve as a handle of the locking rod 410. On the other hand, the elastic member 420 can be arranged inside the sleeve 430. The sleeve 430 protects the elastic member 420 and prevents the elastic member 420 from scratching the operator. It can be understood that the elastic member 420 partially extends out of the sleeve 430, which is convenient for the elastic member 420 to be used. 0 acts on 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, and can also compress the elastic member 420 by pressing the abutment block 440, which is convenient for operation and avoids the operator directly pressing the elastic member 420 and being scratched by the elastic member 420 during operation.

[0091] See also Figures 1 to 2 In one embodiment, the adjusting member 300 is provided with a fixing portion 360 on a side away from the locking rod 410 , one end of the fixing portion 360 is hinged to the base 100 , and the other end is rotatably connected to the pressing wheel 310 .

[0092] It can be understood that one end of the fixing portion 360 is hinged to the base 100 to achieve relative rotation between the adjusting member 300 and the base 100, and the other end of the fixing portion 360 is rotatably connected to the pressure wheel 310, which can drive the pressure wheel 310 away from or close to the guide wheel 200; since the pressure wheel 310 is arranged at the end of the fixing portion 360, the small-range angular rotation of the fixing portion 360 can achieve a large displacement of the pressure wheel 310, which is beneficial to the installation of the tin wire.

[0093] See also Figure 1 In one embodiment, the counting component 700 includes a trigger member 710 and a first sensor 720. The trigger member 710 is fixedly connected to the guide wheel 200. The trigger member 710 includes a trigger portion 711, and the trigger portion 711 is located on the circumferential side of the guide wheel 200. The first sensor 720 is arranged on one side of the guide wheel 200. The first sensor 720 is suitable for detecting the position state of the trigger portion 711.

[0094] It is understood that the trigger member 710 rotates synchronously with the guide wheel 200. The trigger portion 711 is located on the circumference of the guide wheel 200. The first sensor 720 detects the position of the trigger portion 711 to calculate the number of rotations of the trigger member 710, thereby determining the number of rotations of the guide wheel 200. The length of the solder wire passing through the guide wheel 200 is calculated based on the diameter of the guide wheel 200 and the number of rotations.

[0095] Typically, first sensor 720 is a photoelectric sensor. Photoelectric sensors offer high detection accuracy and fast response speed, which helps improve counting accuracy and reduce measurement errors. During detection, the photoelectric sensor does not need to come into direct contact with trigger member 710, preventing wear or damage to trigger member 710 caused by physical contact and minimizing the impact on solder wire transport. First sensor 720 is mounted on base 100. When trigger member 710 rotates, trigger portion 711 passes the probe of third sensor 540. Third sensor 540 detects trigger portion 711, thereby counting the number of rotations of guide wheel 200.

[0096] It is understandable that the trigger member 710 can be a cylinder coaxially arranged with the guide wheel 200, or it can be annular; the embodiment of the utility model can include a fixing screw to connect the trigger member 710 and the guide wheel 200; the trigger member 710 and the guide wheel 200 can be integrally formed to facilitate processing and installation.

[0097] In one embodiment, the trigger member 710 is provided with at least two triggering parts 711, and a detection gap is provided between two adjacent triggering parts 711. The detection gap is suitable for separating two adjacent triggering parts 711, so that different triggering parts 711 can trigger the third sensor respectively.

[0098] See also Figure 1 In one embodiment, the triggering portions 711 are evenly distributed around the trigger member 710 to improve detection accuracy. For example, two triggering portions 711 are symmetrically arranged on opposite sides of the trigger member 710. If the third sensing element detects two triggering portions 711, the guide wheel 200 rotates one revolution. If the third sensing element detects three triggering portions 711, the guide wheel 200 rotates one and a half revolutions, and so on. Similarly, three, four, or five triggering portions 711 can be evenly distributed around the trigger member 710 to improve detection accuracy.

[0099] In one embodiment, the trigger member 710 is a gear, the trigger portion 711 is the teeth of the gear, and the trigger member 710 and the guide wheel 200 are coaxially arranged.

[0100] It is understandable that when the gear rotates, the third sensor 540 detects the teeth of the gear passing by to calculate the number of rotations of the guide wheel 200. Directly using a gear as the trigger 710 has a low procurement cost and does not require the trigger 710 to be separately designed and processed, which facilitates subsequent maintenance and replacement. The output shaft of the driving member 520 connects the guide wheel 200 and the trigger 710. The output shaft of the driving member 520 directly drives the guide wheel 200 and the trigger 710 to rotate synchronously. At the same time, the output shaft of the driving member 520 can serve as a connecting member between the guide wheel 200 and the trigger 710, so that the guide wheel 200 and the trigger 710 are relatively fixed.

[0101] See also Figure 1 In one embodiment, the trigger member 710 is in the form of a sheet. The sheet-like structure can minimize the space occupied by the trigger member 710, making the overall structure of the tin material device more compact. Secondly, the sheet-like design can greatly reduce the material used for the trigger member 710 and reduce the production cost. Since the trigger member 710 is light and thin, it is easy for the trigger member 710 to fit the guide wheel 200, reducing the relative movement between the guide wheel 200 and the trigger member 710, and improving the accuracy of detection. The trigger member 710 can be a metal sheet. While meeting the requirements of lightweight design, the metal sheet has a certain rigidity to prevent the trigger member 710 from being deformed by force during rotation.

[0102] See also Figure 1 In one embodiment, the trigger portion 711 is rod-shaped; compared with other shapes, the width of the rod-shaped trigger portion 711 is narrower, which is conducive to forming a detection gap between two adjacent trigger portions 711 to improve accuracy, and the rod-shaped trigger portion 711 is relatively slender, and the free end of the trigger portion 711 extends outward and corresponds to the probe of the third sensor 540, avoiding other parts such as the guide wheel 200 from affecting the detection work of the third sensor 540.

[0103] See also Figure 3 In one embodiment, the counting component 700 includes an encoder 730 and a second sensor 740. The encoder 730 is arranged on the guide wheel 200 or the reel shaft 820. The second sensor 740 is suitable for detecting the rotation state of the encoder 730, and then obtaining the number of rotations of the guide wheel 200 or the reel shaft 820, so as to facilitate the calculation of the use length of the tin wire.

[0104] Generally, the tin material device also includes a base 510, a coil shaft 820 is rotatably connected to the base 510, an encoder 730 is arranged at the end of the coil shaft 820, and a second sensor 740 is arranged on the inner wall of the base 510 and corresponds to the encoder 730, so as to facilitate the detection of the number of rotations of the coil shaft 820.

[0105] The encoder 730 may also be disposed on the guide wheel 200 , and the second sensor 740 is disposed on the base 100 to detect the number of rotations of the guide wheel 200 , thereby calculating the used length of the solder wire.

[0106] Encoder 730 is a magnetic disk or magnet. Compared to gear-type encoder 730, magnetic encoder 730 can provide higher resolution and more accurately detect rotational position and speed. It is also a contactless sensor that can detect rotational position and speed through a magnetic field without directly contacting the rotating part. This allows for better adaptation to high-speed rotational motion and greater resistance to external vibrations and temperature changes. Second sensor 740 can detect changes in the magnetic field of encoder 730, thereby determining the rotational speed and position of encoder 730, and then calculating the number of rotations of guide wheel 200 or reel shaft 820. Generally, second sensor 740 is a Hall element.

[0107] See also Figure 4 In one embodiment, the tin material device includes a turntable 810 and a fourth sensor 830. The turntable 810 is set on the base 510 and rotates relative to the base 510; the fourth sensor 830 is set between the base 510 and the turntable 810, and the fourth sensor 830 is suitable for detecting the weight of the turntable 810.

[0108] The tin wire can be placed directly on the turntable 810. As the tin wire is used, the weight of the turntable 810 changes accordingly. The usage of the tin wire is judged based on the weight data of the turntable 810 detected by the fourth sensor 830 to detect the remaining tin wire. The tin wire is generally rolled into a coil, and the turntable 810 can rotate flexibly as the tin wire is used to prevent the tin wire from twisting during use and affecting the transmission of the tin wire.

[0109] 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. In other embodiments, the fourth sensor 830 can also be a pressure sensor.

[0110] The second embodiment of the present invention further provides a wave soldering machine, comprising a tin furnace and a tin material device, wherein the tin material device is suitable for supplying tin wire to the tin furnace.

[0111] It can be understood that if the tin material device has the beneficial effects of the above embodiments, then the wave soldering machine will correspondingly have the beneficial effects of the above embodiments.
