[0002] In the manufacturing process of electronic products, electronic components need to be soldered and assembled, and solder wire is required in this process. In modern enterprise production processes, automated equipment is used for soldering, and solder wire is automatically fed through a solder feeding device.

[0003] If solder wire breaks or gets clogged during the feeding process, and the soldering equipment continues to operate, it will lead to product defects and wasted production time. Utility Model Content

[0004] This application aims to provide a solder feeding device and a soldering equipment, which uses a detection mechanism to detect whether the traction mechanism is pulling out solder wire, and controls the traction mechanism to stop working when the traction mechanism is not pulling out solder wire, so as to avoid the occurrence of poor soldering due to the traction mechanism continuing to work when solder breakage or blockage occurs.

[0005] According to a first aspect of this application, this application provides a solder feeding device, including a base and a feeding mechanism, a traction mechanism, a detection mechanism and a guiding assembly mounted on the base;

[0006] The feeding mechanism is used to feed solder wire; the traction mechanism is located at the output end of the feeding mechanism and is used to traction the solder wire to move along the feeding direction; the detection mechanism is located at the output end of the traction mechanism and is electrically connected to the traction mechanism, and is used to detect whether the output end of the traction mechanism has pulled out solder wire.

The second adjusting assembly is movably connected to the base and located at the output end of the detection mechanism. The output guide tube is detachably connected to the second adjusting assembly, and the second adjusting assembly is used to adjust the central axis of the output guide tube to be coaxial with the feeding direction of the solder wire.

[0009] In one embodiment, the guiding assembly further includes a guide tube disposed between the output end of the traction mechanism and the input end of the detection mechanism, the guide tube being used to guide the solder wire toward the detection mechanism.

[0010] In one embodiment, the traction mechanism includes a traction drive assembly, a driving wheel, and a driven wheel. Both the driving wheel and the driven wheel are detachably and rotatably mounted on the base. The traction drive assembly is fixedly connected to the base and is drive-connected to the driving wheel. A traction gap exists between the driving wheel and the driven wheel, the traction gap being adapted to the radial dimension of the solder wire. The driving wheel and the driven wheel are drive-connected. The traction drive assembly drives the driving wheel to rotate, and the driving wheel and the driven wheel traction the solder wire to move along the feeding direction.

[0011] In one embodiment, the traction mechanism further includes a gap elastic adjustment component, which is mounted on the base and is connected to the driven wheel. The gap elastic adjustment component is used to adjust the elastic force between the driven wheel and the driving wheel.

[0012] In one embodiment, the gap elastic adjustment assembly includes an adjusting screw, a stop slider, an elastic element, and an adjusting slider. The base is provided with a groove perpendicular to the feeding direction. The stop slider and the adjusting slider are slidably installed in the groove. The elastic element is disposed between the stop slider and the adjusting slider. The driven wheel is connected to the adjusting slider. The adjusting screw is rotatably installed on the base and screwed to the stop slider. The adjusting screw is rotated to adjust the stop slider to move toward or away from the adjusting slider, thereby adjusting the elastic potential energy of the elastic element.

[0013] In one embodiment, the detection mechanism includes a first clamping wheel, a second clamping wheel, a magnetic component, and a sensor. The first clamping wheel and the second clamping wheel are rotatably connected to the base, and there is a clamping space between the first clamping wheel and the second clamping wheel.

Both the first abutting adjustment component and the second abutting adjustment component are connected to the base. The first abutting adjustment component and the second abutting adjustment component are used to abut against one end of the first bracket and one end of the second bracket, respectively, to adjust the rotation of the first bracket and the second bracket, thereby adjusting the clamping space to align with the feeding direction of the solder wire.

[0017] According to the solder feeding device and welding equipment in the above embodiments, the traction mechanism pulls the solder wire fed by the feeding mechanism to move along the feeding direction. The detection mechanism detects whether the output end of the traction mechanism has pulled out the solder wire, and controls the traction mechanism to stop working when it is detected that the solder wire has not been pulled out. This can avoid the problem of the traction mechanism continuing to work when the solder wire has not been pulled out, which would lead to poor welding quality in the future, and further save production time.

[0036] 200 coils of solder and 201 tin wires. Detailed Implementation

[0037] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0038] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0039] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0040] In related technologies, relative movement occurs between the solder wire and the driving and driven wheels used to guide and transport the solder wire, thereby moving the solder wire along the feeding direction and to the welding mechanism of the welding equipment for welding operations. However, after breaking down large-diameter or extremely fine solder wires, larger-diameter (2.0mm) solder wires are prone to poor solder feeding, while extremely fine-diameter (0.3mm) solder wires are prone to solder breakage or blockage. If solder blockage or breakage occurs and the traction mechanism continues to operate, it will lead to poor soldering of the corresponding electronic components, thus further resulting in low product yield and wasted production time.

[0041] To address the aforementioned problems, this application provides a solder feeding device and a soldering equipment, which uses a detection mechanism to detect whether the traction mechanism is pulling out solder wire, and controls the traction mechanism to stop working when it is not pulling out solder wire, so as to avoid the occurrence of poor soldering due to the traction mechanism continuing to work when solder breakage or blockage occurs.

[0042] Example 1

[0043] See Figure 1 and Figure 2As shown, the solder feeding device 100 provided in this embodiment includes a base 10 and a feeding mechanism 20, a traction mechanism 30, a detection mechanism 40 and a guide assembly 50 installed on the base 10.

[0044] Among them, the feeding mechanism 20, the traction mechanism 30 and the detection mechanism 40 are connected to the base 10 in sequence along the feeding direction of the solder wire. The feeding direction of the solder wire is usually a straight line. The end of the feeding direction of the solder wire corresponds to the position of the welding mechanism in the welding equipment, and then feeds the solder wire to the welding mechanism. The welding mechanism heats the solder wire to weld electronic components.

[0045] The feeding mechanism 20 is used to feed the solder wire 201. The traction mechanism 30 is located at the output end of the feeding mechanism 20 and is used to traction the solder wire to move along the feeding direction. The detection mechanism 40 is located at the output end of the traction mechanism 30 and is electrically connected to the traction mechanism 30. The detection mechanism 40 is used to detect whether the output end of the traction mechanism 30 has pulled out the solder wire 201. When it is detected that the output end of the traction mechanism 30 has not pulled out the solder wire 201, the detection mechanism 40 controls the traction mechanism 30 to stop working. In this way, the problem of poor subsequent soldering quality caused by the traction mechanism 30 continuing to work when the solder wire has not been pulled out can be avoided.

[0046] The guide component 50 is used to guide the solder wire 201 to move along the feeding direction. In other words, the traction mechanism 30 can output the solder wire 201 to the welding mechanism of the welding equipment along the feeding direction through the guiding action of the guide component 50. In a preferred embodiment, the feeding direction of the solder wire is a straight line to avoid bending or even breaking of the solder wire during the conveying process.

[0047] The guiding assembly 50 includes an input guide tube 51 and an output guide tube 52. The input guide tube 51 is located at the output end of the feeding mechanism 20, and the output guide tube 52 is located at the output end of the detection mechanism 40. Both the input guide tube 51 and the output guide tube 52 are detachably mounted on the base 10. The input guide tube 51 is used to convey the solder wire 201 fed by the feeding mechanism 20 to the traction mechanism 30, and the output guide tube 50 is used to output the solder wire that has passed through the detection mechanism 40.

[0048] It should be noted that during the conveying process of solder wire 201 along the feeding direction, the surface of solder wire 201 is usually broken, resulting in pits and unevenness. Therefore, during conveying along the input guide tube 51 and output guide tube 52, it is prone to compression against the ends of the conveying guide tube 51 or output guide tube 52, leading to poor solder feeding and potentially causing solder breakage or blockage. To address this, this application includes a detection mechanism 40 at the output end of the traction mechanism 30 to detect whether the traction mechanism 30 has pulled out solder wire. If solder breakage or blockage occurs, the detection mechanism 40 detects that no solder has been pulled out from the output end of the traction mechanism 30 and sends a non-detection signal to the processor. The processor then generates a stop control signal based on the non-detection signal, and controls the traction mechanism 30 to stop working, preventing further movement of the solder wire.

[0049] The detection mechanism 40 can use an image acquisition device to acquire images of the output end of the traction mechanism 30, and use a processor to compare and analyze the acquired images to determine whether solder is leaking from the output end of the traction mechanism 30. It can also be detected and determined using the principle of electromagnetic induction. In this embodiment, detection is performed using the principle of electromagnetic induction.

[0050] See Figures 6-11 As shown, the detection mechanism 40 includes a first clamping wheel 41, a second clamping wheel 42, a magnetic component 43, and a sensor 44. Both the first clamping wheel 41 and the second clamping wheel 42 are rotatably connected to the base 10, and a clamping space exists between them. This clamping space is used to clamp the solder wire 201 and can rotate as the solder wire moves. In other words, during continuous feeding of the solder wire 201 (without solder blockage or breakage), the movement of the solder wire 201 drives the first clamping wheel 41 and the second clamping wheel 42 to rotate. The magnetic component 43 is coaxially connected to either the first clamping wheel 41 or the second clamping wheel 42; that is, the magnetic component 43 can rotate synchronously with the first clamping wheel 41 or the second clamping wheel 42 connected to it. The sensor 44 is used to detect the electrical signal generated by the rotating magnetic component 43.

[0051] The first clamping wheel 41 and the second clamping wheel 42 are made of non-magnetic metal materials to avoid interference with electromagnetic signals. For example, both the first clamping wheel 41 and the second clamping wheel 42 are made of copper.

[0052] In a specific embodiment, the magnetic component 43 is a magnet with N and S poles. When the magnetic component 43 rotates synchronously with the first clamping wheel 41 or the second clamping wheel 42, the magnetic component 43 generates an alternating magnetic field. The sensor 44 can sense the alternating magnetic field and generate a corresponding electrical signal. The sensor 44 can be connected to a processor, which processes the electrical signal into a voltage difference signal. In other words, the magnetic component 43 can only generate an alternating magnetic field when it rotates synchronously with the first clamping wheel 41 or the second clamping wheel 42. At this time, the sensor 44 can sense the electrical signal, thereby determining that there is solder wire in the clamping space between the first clamping wheel 41 and the second clamping wheel 42, that is, the solder wire 201 has not experienced any breakage or blockage.

[0053] In this embodiment, the detection mechanism 40 further includes a first bracket 45, a second bracket 46, and a clamping elastic member 47. One end of the first bracket 45 and one end of the second bracket 46 are both hinged to the base 10. Specifically, one end of the first bracket 45 is hinged to the base 10 via a first pivot 451, and one end of the second bracket 46 is hinged to the base 10 via a second pivot 461. A first clamping wheel 41 is rotatably disposed at the other end of the first bracket 45, and a second clamping wheel 42 is rotatably disposed at the other end of the second bracket 46. The clamping elastic member 47 connects the other ends of the first bracket 45 and the second bracket 46, bringing the other ends of the first bracket 45 and the second bracket 46 closer together, thereby forming a clamping space between the first clamping wheel 41 and the second clamping wheel 42.

[0054] After the first bracket 45 and the second bracket 46 are hinged to the base 10 via the first rotating shaft 451 and the second rotating shaft 461 respectively, it should be ensured that the clamping space between the first clamping wheel 41 and the second clamping wheel 42 passes through the feeding direction of the solder wire 201. Typically, the installation position of the first bracket 45 and the second bracket 46 can basically ensure that the clamping space passes through the feeding direction of the solder wire 201. In some embodiments, the position of the clamping space is ensured by rotating and adjusting the first bracket 45 and the second bracket 46. See also Figure 8 and Figure 11 As shown, the detection mechanism 40 also includes a first abutting adjustment component 48 and a second abutting adjustment component 49. Both the first abutting adjustment component 48 and the second abutting adjustment component 49 are connected to the base 10. The first abutting adjustment component 48 and the second abutting adjustment component 49 are used to abut one end of the first bracket 45 and one end of the second bracket 46 respectively, so as to adjust the rotation of the first bracket 45 around the first rotating shaft 451 and the rotation of the second bracket 46 around the second rotating shaft 461, thereby adjusting the position of the clamping space between the first clamping wheel 41 and the second clamping wheel 42, so that the clamping space is aligned with the feeding direction of the solder wire 201.

[0055] The direction in which the first abutting component 48 abuts against the first bracket 45 is as follows: Figure 11As shown by the vertical downward arrow, the first abutting component 48 abuts one end of the first bracket 45, causing the other end of the first bracket 45 to rotate around the first pivot 451 in a direction away from the second bracket 46. The direction in which the second abutting component 49 abuts the second bracket 46 is as follows. Figure 11 As shown by the vertical upward arrow, the second abutting component 49 abuts one end of the second bracket 46, causing the other end of the second bracket 46 to rotate around the second pivot 461 toward the direction of the first bracket 45. Through continuous adjustment, the clamping space can be aligned with the feeding direction of the solder wire 201.

[0056] Of course, by using the first abutting component 48 and the second abutting component 49 to abut one end of the first bracket 45 and one end of the second bracket 46 respectively, the size of the clamping space can be adjusted to accommodate the transmission of solder wires 201 with different diameters.

[0057] When threading the solder wire 201 into the guide assembly 50, to ensure that the solder wire 201 can be threaded through the input guide tube 51 and the output guide tube 52 of the guide assembly 50 in the feeding direction, such as... Figures 6-9 As shown, the guide assembly 50 also includes a first adjustment assembly 54 and a second adjustment assembly 55. The first adjustment assembly 54 is movably connected to the base 10 and connected to the feeding mechanism 20. The input guide tube 51 is detachably connected to the first adjustment assembly 54. The first adjustment assembly 54 is used to adjust the central axis of the input guide tube 51 to be coaxial with the feeding direction of the solder wire 201, and at the same time drive the feeding mechanism 20 to move synchronously, so that the solder wire 201 fed out by the feeding mechanism 20 can be coaxial with the central axis of the input guide tube 51. The second adjustment assembly 55 is movably connected to the base 10 and located at the output end of the detection mechanism 40. The output guide tube 52 is detachably connected to the second adjustment assembly 55. The second adjustment assembly 55 is used to adjust the central axis of the output guide tube 52 to be coaxial with the feeding direction of the solder wire 201.

[0058] In a specific embodiment, the input guide tube 51 is detachably mounted on the first adjustment assembly 54 in a feeding direction parallel to the solder wire 201, and the output guide tube 52 is detachably mounted on the second adjustment assembly 55 in a feeding direction parallel to the solder wire 201. Both the first adjustment assembly 54 and the second adjustment assembly 55 can move in a direction perpendicular to the feeding direction of the solder wire 201. Thus, when the first adjustment assembly 54 and the second adjustment assembly 55 move in a direction perpendicular to the feeding direction of the solder wire 201, the central axes of the input guide tube 51 and the output guide tube 52 can be adjusted to be coaxial with the feeding direction of the solder wire 201.

[0059] To facilitate the guidance of solder wires 201 with different diameters, in this embodiment, the input guide tube 51 and the output guide tube 52 are detachably connected to the first adjustment component 54 and the second adjustment component 55, respectively. For example, the input guide tube 51 and the output guide tube 52 are respectively connected to the first adjustment component 54 and the second adjustment component 55 through mounting holes on the first adjustment component 54 and the second adjustment component 55, so that solder wires 201 with different diameters can be adapted by replacing the input guide tube 51 and the output guide tube 52 with different inner diameters.

[0060] In this embodiment, the first adjustment component 54 includes a first movable plate 541 and a first locking member 543. The first movable plate 541 has a first adjustment hole 542. The first movable plate 541 is movably mounted on the base 10 in a direction perpendicular to the feeding direction of the solder wire 201 and is located at the output end of the feeding mechanism 20. The input guide tube 51 is detachably connected to the first movable plate 541. When the first movable plate 541 moves in a direction perpendicular to the feeding direction of the solder wire 201 to a position where the central axis of the input guide tube 51 is coaxial with the feeding direction of the solder wire 201, the first movable plate 541 is positioned on the base 10 by the first locking member 543 passing through the first adjustment hole 542 and locking (e.g., screwed) onto the base 10. The second adjustment assembly 55 includes a second movable plate 551 and a second locking member 553. The second movable plate 551 has a second adjustment hole 552. The second movable plate 551 is movably mounted on the base 10 in a direction perpendicular to the feeding direction of the solder wire 201 and is located at the output end of the detection mechanism 40. The output guide tube 52 is detachably connected to the second movable plate 551. When the second movable plate 551 moves along the feeding direction perpendicular to the solder wire 201 to a position where the central axis of the output guide tube 52 is coaxial with the feeding direction of the solder wire 201, the second movable plate 551 is positioned on the base 10 by the second locking member 553 passing through the second adjustment hole 552 and locking (e.g., screwed) onto the base 10.

[0061] In one embodiment, the traction mechanism 30 is disposed near the first adjusting component 54, and the detection mechanism 40 is disposed near the second adjusting component 55. The first abutting adjusting component 48 and the second abutting adjusting component 49, which respectively adjust the abutment of the first bracket 45 and the second bracket 46, are both disposed on the second movable plate 551 of the second adjusting component 55. The first abutting adjusting component 48 and the second abutting component 49 are both set screws. The first screw hole 544 and the second screw hole 545 are respectively provided on the first movable plate 551 at the outer side of one end of the first bracket 45 and the outer side of one end of the second bracket 46. The first abutting adjusting component 48 and the second adjusting component 49 are screwed into the first screw hole 544 and the second screw hole 545 respectively. The ends of the first abutting component 48 and the second abutting adjusting component 49 extend to the outside of the first screw hole 544 and the second screw hole 545 and abut against one end of the first bracket 45 and one end of the second bracket 46, so that the first bracket 45 and the second bracket 46 can be adjusted when the first abutting adjusting component 48 and the second abutting component 49 are rotated.

[0062] Of course, for ease of adjustment of the first abutment adjustment component 48 and the second abutment adjustment component 49, see [link to relevant documentation]. Figure 8 As shown, the base 10 is provided with a first clearance hole 11 and a second clearance hole 12. The first abutment adjustment component 48 is exposed through the first clearance hole 11, and the second abutment adjustment component 49 is exposed through the second clearance hole 12, so that the first abutment adjustment component 48 and the second abutment adjustment component 49 can be adjusted by passing through the first clearance hole 11 and the second clearance hole 12 respectively. For example, an Allen wrench can be used to screw and adjust the first abutment adjustment component 48 and the second abutment adjustment component 49 through the first clearance hole 11 and the second clearance hole 12.

[0063] In the above embodiments, the arrangement of the first abutment adjustment component 48 and the second abutment adjustment component 49 on the second movable plate 551 of the second adjustment component 55 saves structural installation space and makes the structure more compact. Of course, the first abutment adjustment component 48 and the second abutment adjustment component 49 can also be arranged on the base 10, which can achieve the same adjustment function.

[0064] See Figure 2 , Figures 5-7 As shown, the guide assembly 50 also includes a guide tube 53, which is disposed between the output end of the traction mechanism 30 and the input end of the detection mechanism 40. The guide tube 53 is used to guide the solder wire to move towards the detection mechanism 40. Of course, in other embodiments, the guide tube 53 may not be provided.

[0065] See Figure 2 , Figure 6 and Figure 7As shown, the traction mechanism 30 includes a traction drive assembly 31, a driving wheel 32, and a driven wheel 33. Both the driving wheel 32 and the driven wheel 33 are detachably and rotatably mounted on the base 10. The traction drive assembly 31 is fixedly connected to the base 10 and is drive-connected to the driving wheel 32. A traction gap exists between the driving wheel 32 and the driven wheel 33, which is adapted to the radial dimension of the solder wire. The drive wheel 32 and the driven wheel 33 are drive-connected so that the driven wheel 33 can rotate synchronously with the rotating driving wheel 32. In this embodiment, a driving gear 321 is coaxially fixedly connected to the driving wheel 32, and a driven gear 331 is coaxially fixedly connected to the driven wheel 33. The driving gear 321 and the driven gear 331 mesh, thereby drive-connecting the driving wheel 32 and the driven wheel 33. The traction drive assembly 31 is used to drive the drive wheel 32 to rotate. The rotating drive wheel 32 drives the driven wheel 33 to rotate synchronously through the meshing drive gear 321 and driven gear 331. The solder wire 201 is inserted into the traction gap between the drive wheel 32 and the driven wheel 33. The rotating drive wheel 32 and driven wheel 33 are used to pull the solder wire 201 to move along the feeding direction.

[0066] It is understandable that the size of the traction gap is less than or equal to the radial dimension of the solder wire 201, so that friction can be generated between the drive wheel 32 and the driven wheel 33. Under the action of friction, the solder wire 201 converts the rotational motion of the drive wheel 32 and the driven wheel 33 into linear motion along the feeding direction, thereby moving.

[0067] The driving wheel 32 and driven wheel 33 are detachably mounted on the base 10. This configuration allows for the replacement of driving wheels 32 and driven wheels 33 with different radial dimensions depending on the diameter of the solder wire 201. For example, for solder wire 201 with a diameter of 0.3mm-0.5mm, rubber driving wheels 32 and driven wheels 33 can be used; for solder wire 201 with a diameter of 0.8mm-2.0mm, steel driving wheels 32 and driven wheels 33 can be used.

[0068] In some embodiments, when a driving wheel 32 and a driven wheel 33 made of the same material are being pulled, the size of the traction gap needs to be adjusted when pulling a solder wire 201 with one of the wire diameter ranges (e.g., 0.3mm-0.5mm). In this embodiment, see [link to relevant documentation]. Figure 6 , Figure 7 and Figure 9 As shown, the traction mechanism 30 also includes a gap elastic adjustment component 34, which is installed on the base 10 and is connected to the driven wheel 33. The gap elastic adjustment component 34 is used to adjust the elastic force between the driven wheel 33 and the driving wheel 32, so that the traction gap is formed into an elastic gap, thereby adapting to tin wires 201 of different diameters.

[0069] like Figure 9As shown, the gap elastic adjustment assembly 34 includes an adjusting screw 341, a stop slider 342, an elastic element 343, and an adjusting slider 344. The base 10 has a groove 13 perpendicular to the feeding direction. Both the stop slider 342 and the adjusting slider 344 are slidably installed in the groove 13. The elastic element 343 is disposed between the stop slider 342 and the adjusting slider 344. The driven wheel 33 is connected to the adjusting slider 344. The adjusting screw 341 is rotatably mounted on the base 10 and screwed to the stop slider 342. The adjusting screw 341 is rotated to adjust the movement of the stop slider 342 toward or away from the adjusting slider 344, thereby adjusting the elastic potential energy of the elastic element 343. The elastic force applied by the elastic element 343 to the adjusting slider 344 adjusts the elastic force of the traction gap between the driving wheel 32 and the driven wheel 33.

[0070] See Figure 3 and Figure 4 As shown, the feeding mechanism 20 includes a support 21 and a feeding shaft 22. The support 21 is connected to the first adjustment component 54. The feeding shaft 22 is basically perpendicular to the support 21. The feeding roll 200 is rotatably threaded on the feeding shaft 22. The feeding roll 200 is wound with solder wire 201. By adjusting the first adjustment component 54, the support 21 can be moved synchronously, thereby adjusting the solder wire 201 fed by the feeding roll 200 to be coaxial with the feeding direction.

[0071] A limiting member 23 is also connected to the feeding shaft 22. The limiting member 23 can limit the feeding roll 200 to prevent it from detaching from the feeding shaft 22. Specifically, the feeding shaft 22 has a mounting hole 221 at the end away from the bracket 21. The limiting member 23 has a through hole 231. The rotating shaft 24 passes through the through hole 231 and is fixed in the mounting hole 221. The rotating shaft 24 has a limiting part 241. The through hole 231 is a stepped hole. An elastic member 25 is provided between the limiting part 241 and the stepped surface of the through hole 231. The elastic member 25 limits the limiting member 23 at the end of the feeding shaft 22 away from the bracket 21. By pulling the limiting member 23, the limiting member 23 can be detached from the feeding shaft 22. At this time, the limiting member 23 can be adjusted to be coaxial with the feeding shaft 22, so that the feeding roll 200 can be installed in a through-hole manner or the feeding roll 200 can be removed from the feeding shaft 22. Loosen the limiting member 23 and adjust its position so that the limiting member 23 is at least partially offset from the feeding shaft 22 in the axial direction of the feeding shaft 22, thereby limiting the feeding roll 200 by the limiting member 23.

[0072] Example 2

[0073] This embodiment provides a welding device, including the solder feeding device 100 in Embodiment 1. The welding device also includes a welding mechanism. The solder feeding device 100 feeds the solder wire 201 to the welding mechanism. For the specific structure and function of the solder feeding device 100, please refer to the above embodiment.

[0074] In summary, in the solder feeding device and welding equipment provided by this utility model, the traction mechanism pulls the solder wire released by the feeding mechanism to move along the feeding direction. The detection mechanism detects whether the output end of the traction mechanism has pulled out the solder wire, and controls the traction mechanism to stop working when it is detected that the solder wire has not been pulled out. This can avoid the problem of the traction mechanism continuing to work when the solder wire has not been pulled out, which would lead to poor welding quality in the future, and further save production time.

[0075] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
