Description

Technical Field

[0001] This application relates to the technical field of welding equipment, and in particular to an automatic feeding device for a soldering machine. Background Technology

[0002] Welding wire is a metal wire used as filler metal or simultaneously as a conductive electrode in welding. In gas welding and tungsten inert gas welding, the welding wire is used as filler metal. In submerged arc welding, electroslag welding, and other gas metal arc welding, the welding wire serves as both filler metal and conductive electrode.

[0003] Currently, welding wire is wound on a rotating drum and placed on a soldering machine for soldering. Automatic soldering machines are equipped with an automatic solder feeding device to deliver the welding wire to the soldering point, thus facilitating soldering operations. The automatic solder feeding device generally includes a mounting platform, a lead wire assembly mounted on the mounting platform, and a wire feeding hose on one side of the lead wire assembly for threading the welding wire. The lead wire assembly pulls the welding wire through the wire feeding hose. The lead wire assembly includes a drive wheel rotatably mounted on the mounting platform, a driven wheel arranged relative to the drive wheel, and a drive component for driving the drive wheel to rotate. A threading gap is provided between the drive wheel and the driven wheel for threading the welding wire. When the drive component drives the drive wheel to rotate, since both the drive wheel and the driven wheel are pressed against the periphery of the welding wire, the rotation of the drive wheel moves the welding wire toward the wire feeding hose. Simultaneously, the driven wheel rotates accordingly, driving the welding wire to move, thereby extracting and moving the welding wire into the wire feeding hose, facilitating the feeding of the welding wire. However, during the wire threading process, the end of the wire wound on the rotating drum needs to be manually threaded into the threading gap between the drive wheel and the driven wheel by the operator, which results in a low degree of automation in the wire feeding process. Summary of the Invention

[0004] In order to improve the automation level of solder wire feeding in soldering machines, this application provides an automatic feeding device for soldering machines.

[0005] This application provides an automatic feeding device for a soldering machine, which adopts the following technical solution:

[0006] The device includes a fixed base, a mounting frame disposed on one side of the fixed base for rotating and mounting a rotating drum for winding welding wire, a wire feeding hose disposed on the other side of the fixed base for feeding welding wire to a soldering machine, and a feeding device for pulling the welding wire wound on the rotating drum to the port of the wire feeding hose. The feeding device includes a drive wheel rotatably disposed on the fixed base, a driven wheel arranged opposite to the drive wheel, and a first driving member for driving the drive wheel to rotate. It also includes a wire pulling device disposed on the mounting frame for pulling off the wound welding wire, a positioning device slidably disposed on the fixed base for orienting the pulled-off welding wire, and a clamping device for conveying the end of the welding wire to a position near the feeding device.

[0007] By adopting the above technical solution, when the automatic feeding equipment of the soldering machine feeds the solder wire, the end of the solder wire wound on the rotating drum is pulled off by the wire pulling device, and the pulled-off end of the solder wire is fixed through the positioning device to position the solder wire. Then, the solder wire passing through the positioning device is clamped and transported to the vicinity of the feeding device by the clamping device. The first driving component is activated, and the first driving component drives the driving wheel to rotate, thereby driving the driven wheel to clamp the end of the solder wire for feeding, thereby realizing the automatic feeding of the solder wire and improving the automation level of solder wire feeding of the soldering machine.

[0008] Optionally, the wire-picking device includes a fixed bracket fixedly mounted on the mounting frame and a wire-picking plate mounted on the fixed bracket and arranged facing the rotating drum. The mounting frame is provided with a second driving member for driving the rotating drum to rotate, and the wire-picking plate rotates and abuts against the welding wire.

[0009] By adopting the above technical solution, when the wire-pulling device pulls the welding wire wound on the rotating drum, the second driving component is activated, which drives the rotating drum to rotate. The wire-pulling plate, which is pressed against the welding wire wound on the rotating drum, pulls up the end of the welding wire. As the rotating drum rotates, the wire-pulling plate continues to pull the welding wire down, thus facilitating the removal of the end of the welding wire.

[0010] Optionally, the positioning device includes a wire gathering component slidably disposed on one side of the mounting frame for threading the welding wire, and a first sliding assembly for driving the wire gathering component to slide horizontally. The wire gathering component is flared and has a large opening facing towards the mounting frame. The wire gathering component has a positioning channel for threading the welding wire.

[0011] By adopting the above technical solution, after the end of the welding wire is pulled off by the wire pulling device, the first sliding component drives the wire gathering component to slide towards the side closer to the rotating drum, so that the wire gathering component gathers the pulled-off end of the welding wire in the positioning channel, so that the welding wire is threaded through the positioning channel, thereby facilitating the limiting of the end of the welding wire and facilitating subsequent clamping and feeding.

[0012] Optionally, the clamping device includes a chuck for feeding and clamping the welding wire and a second sliding assembly for driving the chuck to slide horizontally. The chuck has a wire-feeding through hole for feeding the welding wire, and a wire-clamping assembly for clamping the welding wire is provided on one side of the wire-feeding through hole.

[0013] By adopting the above technical solution, after the end of the welding wire passes through the wire gathering member, the second sliding component drives the clamp to slide towards the side closer to the wire gathering member, so that the end of the welding wire passes through the wire through hole of the clamp, and the welding wire can be clamped by the clamping component in the clamp. Thus, the clamp can be driven towards the side closer to the feeding device by the second sliding component, so that the welding wire can be fed after being clamped by the clamp.

[0014] Optionally, the wire clamping assembly includes a stop block that slides against one side of the welding wire and a driving block for driving the stop block to slide. The clamping member has a driving insertion hole on one side of the wire through hole for the driving block to slide through. The clamping member has a mounting sliding hole on the wall of the driving insertion hole that communicates with the wire through hole and is used for the driving block to slide through. The driving block has a fixing groove for the side of the stop block away from the wire through hole to be engaged. On both sides of the fixing groove, there are guide slopes for driving the stop block to pass through the mounting sliding hole and abut against the periphery of the welding wire. Both ends of the driving block are provided with sliding guide blocks that pass through the driving insertion hole and push the driving block to slide.

[0015] By adopting the above technical solution, when the chuck slides towards the side closer to the wire gathering component under the drive of the second sliding assembly, the sliding guide block abuts against one end face of the wire gathering component, thereby causing the driving block to slide through the driving socket. The guide slope on the driving block slides against one side of the abutment block, thereby driving the abutment block to slide through the mounting sliding hole, thus making the abutment block press against the periphery of the welding wire, thereby achieving the clamping effect of the wire clamping assembly on the welding wire. When the end of the chuck clamping the welding wire slides towards the feeding device, the sliding guide block on the chuck abuts against the positioning vertical plate near the feeding device, thereby causing the driving block to slide through the driving socket, and the abutment block to pass through the mounting sliding hole and engage in the fixing groove, thereby allowing the abutment block to release the welding wire, facilitating subsequent material feeding.

[0016] Optionally, the automatic feeding device of the soldering machine further includes a clearance mechanism for mounting the driven wheel. The driven wheel has a first station and a second station under the drive of the clearance mechanism. When the driven wheel is in the first station, the driven wheel abuts against the periphery of the threaded solder wire. When the driven wheel is in the second station, a clearance gap is left between the driving wheel and the driven wheel for threading the solder wire.

[0017] By adopting the above technical solution, when the welding wire is fed to the vicinity of the feeding device through the clamping device, the driven wheel is in the second working position under the drive of the yielding mechanism. This facilitates the welding wire to pass through the yielding gap, thereby reducing the interference of the driven wheel on the wire passing through. After the end of the welding wire passes through the yielding gap, the yielding mechanism drives the driven wheel to return to the first working position, so that the driven wheel is pressed against the periphery of the welding wire. Thus, the welding wire can be conveyed through the driving wheel and the driven wheel.

[0018] Optionally, the yielding mechanism includes a rotating seat rotatably mounted on the fixed base for mounting the driven wheel, a toggle assembly for rotating the rotating seat, and a reset assembly disposed on one side of the fixed base and connected to the driven wheel for driving the rotating seat to reset. The fixed base is provided with a rotating shaft for rotating the rotating seat, and the toggle assembly is disposed on the side of the rotating seat away from the rotating shaft.

[0019] By adopting the above technical solution, when the driven wheel is driven by the yielding mechanism, the actuating component is actuated, causing the rotating seat to rotate around the rotating shaft, thereby driving the driven wheel to slide away from the driving wheel. When the actuating component is released, the driven wheel returns to the first position under the drive of the reset component, so that the rotating seat resets around the rotating shaft.

[0020] Optionally, the fixed base is provided with a positioning vertical plate for threading welding wire between the feeding device and the clamping device. The actuating component includes a lever block slidably disposed on the positioning vertical plate and a connecting shaft connecting the lever block and the rotating seat. The positioning vertical plate is provided with a strip hole for sliding installation of the lever block. One side of the lever block passes through the strip hole and is fixedly connected to the connecting shaft, while the other side passes through the strip hole for actuating the lever block.

[0021] By adopting the above technical solution, the positioning vertical plate set on the fixed base can be used for fixing and threading the welding wire, thereby positioning the threading of the welding wire. When the rotating seat is driven to rotate by the actuating component and the driven wheel slides, the actuating block is actuated, causing the actuating block to slide in the strip hole, thereby driving the rotating seat to rotate around the rotating axis, causing the rotating seat to drive the driven wheel to slide, thus facilitating the actuation of the driven wheel.

[0022] Optionally, the automatic feeding device of the soldering machine further includes a linkage mechanism for driving the sliding of the dial block. The linkage mechanism includes a linkage assembly connected to the side of the dial block away from the rotating seat and a push block disposed on the chuck and used to actuate the linkage assembly. The push block pushes the linkage assembly and drives the dial block to slide.

[0023] By adopting the above technical solution, when the chuck clamps the welding wire and slides towards the side close to the feeding device, the push block on the chuck actuates the connecting rod assembly, causing the connecting rod assembly to push the push block to slide, thereby driving the actuating assembly to drive the rotating seat to rotate, which in turn drives the driven wheel to slide. Thus, the sliding of the chuck can trigger the operation of the actuating assembly, so that the end of the welding wire clamped by the chuck passes through the positioning vertical plate and through the clearance between the driving wheel and the driven wheel, thereby realizing the linkage of the two devices.

[0024] Optionally, the reset assembly includes a fixed vertical plate disposed on the fixed base, a first shaft for connecting the driven wheel, a second shaft connected to the fixed vertical plate on the side facing the driven wheel, and a reset spring for connecting the first shaft and the second shaft.

[0025] By adopting the above technical solution, when the rotating seat is rotated by the toggle assembly, the driven wheel slides, thereby compressing the return spring. When the toggle block is released, the return spring drives the driven wheel to reset, thus realizing the reset of the driven wheel and the toggle block.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application includes a fixed base, a mounting frame, a wire feeding hose, a feeding device, a wire pulling device, a positioning device, and a clamping device. The wire pulling device pulls the end of the welding wire wound on the rotating drum on the mounting frame, the positioning device fixes the welding wire through, the clamping device clamps the end of the welding wire and conveys it to the feeding device, and then the feeding device directionally conveys the welding wire to the wire feeding hose, thereby realizing the automation of welding wire feeding.

[0028] 2. The clamping component of this application is provided with a wire clamping assembly for clamping welding wire. The wire clamping assembly includes a stop block that slides against one side of the welding wire and a driving block for driving the stop block to slide. The clamping component has a driving insertion hole for the driving block to slide through. The clamping component has a mounting sliding hole on the hole wall of the driving insertion hole that communicates with the wire through hole and is used for the driving block to slide through. The driving block has a fixing groove for one side of the stop block to be engaged and a guide slope is provided on both sides of the fixing groove. Both ends of the driving block are provided with sliding guide blocks that pass through the driving insertion hole. Thus, the stop block can be tightened and loosened by pressing the sliding guide block and driving the driving block.

[0029] 3. This application also includes a linkage mechanism for driving the sliding of the lever. The linkage mechanism includes a linkage assembly connected to the side of the lever away from the rotating seat and a push block disposed on the chuck and used to actuate the linkage assembly. The push block on the chuck actuates the linkage assembly, causing the linkage assembly to push the lever to slide, thereby driving the actuation assembly to drive the rotating seat to rotate, thereby driving the driven wheel to slide. Thus, the operation of the actuation assembly can be triggered by the sliding of the chuck. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] The accompanying drawings of this application embodiment provide a coordinate system XYZ, where the positive direction of the X-axis represents the front side, the negative direction of the X-axis represents the rear side, the positive direction of the Y-axis represents the left side, the negative direction of the Y-axis represents the right side, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0038] This application discloses an automatic feeding device for a soldering machine. See also... Figure 1 The automatic feeding device of the soldering machine includes a fixed base 1, a mounting frame 2 for rotating and mounting a rotating drum for winding solder wire on the right side of the fixed base 1, a wire pulling device 3 for pulling off the wound solder wire on the mounting frame 2, a positioning device 4 for directional threading of the pulled-off solder wire slidably mounted on the fixed base 1, a wire feeding hose 5 for feeding solder wire to the soldering machine on the left side of the fixed base 1, a feeding device 6 for pulling the solder wire wound on the rotating drum to the port of the feeding hose 5, and a clamping device 7 for conveying the end of the solder wire to a location near the feeding device 6.

[0039] See Figure 2 In this embodiment, the mounting frame 2 is provided with an overhead shaft frame, which includes a shaft for the rotating drum to be fixedly inserted and abutment plates that abut against the front and rear sides of the rotating drum. A second driving member 21 for driving the shaft to rotate is provided on the front side of the mounting frame 2, thereby driving the rotating drum to rotate. The welding wire is neatly arranged and wound around the rotating drum, facilitating the transfer of the welding wire. The wire-picking device 3 includes a fixed bracket 31 fixedly mounted on the mounting frame 2 and a wire-picking plate 32 mounted on the fixed bracket 31 and facing the rotating drum. In this embodiment, the wire-picking plate 32 is made of a material with a certain degree of elasticity, and a scraper of rigid material is provided on the side edge of the wire-picking plate 32 near the rotating drum, so that the scraper rotates and presses against the welding wire. When using the wire-pulling device 3 to pull the welding wire wound on the rotating drum, the second drive unit 21 is activated, causing the second drive unit 21 to drive the rotating drum to rotate. The wire-pulling plate 32, which is pressed against the welding wire wound on the rotating drum, pulls up the end of the welding wire. As the rotating drum rotates, the wire-pulling plate 32 continues to pull the welding wire down, thus facilitating the removal of the end of the welding wire.

[0040] See Figure 1The positioning device 4 includes a wire gathering member 41 slidably disposed on the left side of the mounting frame 2 for threading the welding wire, and a first sliding component 42 for driving the wire gathering member 41 to slide horizontally in the left and right directions. In this embodiment, the first sliding component 42 is configured as a linear module, which is a relatively conventional structure and will not be described in detail here. The wire gathering member 41 is flared and the opening gradually decreases in size away from the rotating drum. A positioning channel 411 for threading the welding wire is provided inside the wire gathering member 41. The positioning channel 411 is also flared and gradually decreases in size away from the rotating drum. When the end of the welding wire is pulled off by the wire pulling device 3, the first sliding component 42 drives the wire gathering member 41 to slide towards the side closer to the rotating drum, so that the wire gathering member 41 gathers the end of the pulled-off welding wire in the positioning channel 411, allowing the welding wire to pass through the positioning channel 411 for threading. This facilitates the limiting of the end of the welding wire and facilitates subsequent clamping and feeding.

[0041] See Figure 3 and Figure 4 The clamping device 7 includes a clamping member 71 for threading and holding the welding wire, and a second sliding assembly 72 for driving the clamping member 71 to slide horizontally. The clamping member 71 has a threading through hole 711 for threading the welding wire, and a clamping assembly 73 for holding the welding wire is provided on one side of the threading through hole 711. In this embodiment, the clamping member 71 is a rectangular block, and the threading through hole 711 is a strip-shaped through hole extending through its left and right ends. After the end of the welding wire passes through the wire gathering member 41, the second sliding assembly 72 drives the clamping member 71 to slide towards the side closer to the wire gathering member 41, so that the end of the welding wire passes through the threading through hole 711 of the clamping member 71, and the clamping assembly 73 within the clamping member 71 can clamp the welding wire. Therefore, the second sliding assembly 72 can drive the clamping member 71 towards the side closer to the feeding device 6, thereby clamping and feeding the welding wire through the clamping member 71.

[0042] See Figure 3 and Figure 4The wire clamping assembly 73 includes a stop block 731 that slides against one side of the welding wire and a driving block 732 for driving the stop block 731 to slide. The clamp 71 has a driving insertion hole 712 on one side of the wire through hole 711 for the driving block 732 to slide through. The clamp 71 also has a mounting sliding hole 713 on the wall of the driving insertion hole 712 that communicates with the wire through hole 711 and allows the driving block 732 to slide through. The driving block 732 has a fixing groove 7321 for the stop block 731 to engage on the side opposite to the wire through hole 711. On both sides of the fixing groove 7321 are guide slopes 7322 for driving the stop block 731 to pass through the mounting sliding hole 713 and abut against the periphery of the welding wire. Both ends of the driving block 732 have sliding guide blocks 7323 that pass through the driving insertion hole 712 and push the driving block 732 to slide. In this embodiment, the drive block 732 is configured as a long strip block, so that the drive socket 712 is opened as a strip hole 822 adapted to the drive block 732, the abutment block 731 is configured as a square block, and the mounting slider is configured as a through hole adapted to the side of the abutment block 731 near the wire through hole 711.

[0043] When the clamp 71 slides toward the side closer to the wire gathering member 41 under the drive of the second sliding assembly 72, the sliding guide block 7323 abuts against one end face of the wire gathering member 41, thereby causing the driving block 732 to slide through the driving insertion hole 712. The guide slope 7322 on the driving block 732 slides against one side of the abutment block 731, thereby driving the abutment block 731 to slide through the mounting sliding hole 713, thereby causing the abutment block 731 to press against the periphery of the welding wire, thereby achieving the clamping effect of the wire clamping assembly 73 on the welding wire. When the clamp 71 clamps the end of the welding wire and slides toward the feeding device 6, the sliding guide block 7323 on the clamp 71 abuts against the positioning vertical plate 82 near the feeding device 6, thereby causing the driving block 732 to slide through the driving insertion hole 712, and causing the abutment block 731 to pass through the mounting sliding hole 713 and be engaged in the fixing groove 7321. This allows the abutment block 731 to release the welding wire, facilitating subsequent material feeding.

[0044] See Figure 5The feeding device 6 includes a driving wheel 61 rotatably mounted on a fixed base 1, a driven wheel 62 arranged opposite to the driving wheel 61, and a first driving member for driving the driving wheel 61 to rotate. In this embodiment, the feeding device 6 is mounted on a limiting seat 8 fixedly mounted on the fixed base 1. The limiting seat 8 includes a lower base plate 81 for mounting the driving wheel 61 and the driven wheel 62, a positioning vertical plate 82 on the lower base plate 81 near the clamping device 7 for allowing the welding wire to pass through, and a limiting vertical plate 83 on the lower base plate 81 away from the clamping device 7 for mounting the wire feeding hose 5. The positioning vertical plate 82 is provided with a positioning sleeve shaft 821 for directional insertion of the welding wire, and the positioning sleeve shaft 821 is arranged correspondingly to the clamping device 7. The first driving member is disposed inside the fixed base 1 and is configured as a rotary motor for driving the driving wheel 61 to rotate; it is not shown in the figure. Driven wheel 62 abuts against the other side of the welding wire, and a drive shaft sleeve 621 that rotates and abuts against the welding wire is rotatably sleeved on the outer periphery of driven wheel 62. Thus, the welding wire can be pushed towards the wire feeding hose 5 by the driving force of drive wheel 61 and driven wheel 62.

[0045] See Figure 5 The limiting seat 8 is also equipped with a clearance mechanism 9 for mounting the driven wheel 62. Driven by the clearance mechanism 9, the driven wheel 62 has a first position and a second position. When the driven wheel 62 is in the first position, it abuts against the periphery of the threaded welding wire. When the driven wheel 62 is in the second position, a clearance gap is left between the driving wheel 61 and the driven wheel 62 for the welding wire to pass through. When the welding wire is fed to the vicinity of the feeding device 6 by the clamping device 7, the driven wheel 62 is in the second position driven by the clearance mechanism 9. This facilitates the welding wire passing through the clearance gap, thereby reducing interference between the driven wheel 62 and the welding wire. After the end of the welding wire passes through the clearance gap, the clearance mechanism 9 drives the driven wheel 62 back to the first position, so that the driven wheel 62 abuts against the periphery of the welding wire. Thus, the welding wire can be conveyed through the driving wheel 61 and the driven wheel 62.

[0046] See Figure 5The yielding mechanism 9 includes a rotating seat 91 rotatably mounted on the fixed base 1 for mounting the driven wheel 62, a toggle assembly 92 for rotating the rotating seat 91, and a reset assembly 93 located on the front side of the fixed base 1 and connected to the driven wheel 62 for driving the rotating seat 91 to reset. The fixed base 1 has a rotating shaft 11 near its left side for rotating the rotating seat 91. The rotating shaft 11 is a square piece extending from left to right along a water direction. The toggle assembly 92 is located on the side of the rotating seat 91 away from the rotating shaft 11. When the driven wheel 62 is driven by the yielding mechanism 9, the toggle assembly 92 is actuated, causing the rotating seat 91 to rotate around the rotating shaft 11, thereby causing the driven wheel 62 to slide away from the driving wheel 61. When the toggle assembly 92 is released, the driven wheel 62 returns to its first position under the action of the reset assembly 93, causing the rotating seat 91 to reset around the rotating shaft 11.

[0047] See Figure 5 The actuating assembly 92 includes a toggle block 921 slidably mounted on a positioning vertical plate 82 and a connecting shaft 922 connecting the toggle block 921 and the rotating seat 91. The positioning vertical plate 82 has a slotted hole 822 for sliding installation of the toggle block 921. The left side of the toggle block 921 extends through the slotted hole 822 and is fixedly connected to the connecting shaft 922, while the right side extends through the slotted hole 822 for actuating the toggle block 921. In this embodiment, one end of the connecting shaft 922 is fixedly connected to the rotating seat 91, and the other end of the connecting shaft 922 is fixedly connected to the toggle block 921. The positioning vertical plate 82 provided on the fixed base 1 can be used for fixing and threading the welding wire, thereby positioning the threading of the welding wire. When the rotating seat 91 is driven to rotate by the actuating component 92, the driven wheel 62 is slid, and the actuating block 921 is actuated, so that the actuating block 921 slides in the strip hole 822, thereby driving the rotating seat 91 to rotate around the rotating shaft 11, so that the rotating seat 91 drives the driven wheel 62 to slide, thereby facilitating the actuation of the driven wheel 62.

[0048] See Figure 3The automatic feeding device of the soldering machine also includes a linkage mechanism 94 for driving the sliding of the push block 921. The linkage mechanism 94 includes a connecting rod assembly 941 connected to the side of the push block 921 away from the rotating seat 91, and a push block 942 disposed on the chuck 71 for actuating the connecting rod assembly 941. The push block 942 pushes the connecting rod assembly 941 and drives the push block 921 to slide. In this embodiment, the connecting rod assembly 941 includes a first connecting rod with one end fixedly and rotatably connected to the positioning vertical plate 82, and a second connecting rod with one end rotatably connected to the first connecting rod and the other end rotatably connected to the push block 921. The first connecting rod and the second connecting rod are arranged parallel to the plane of the fixed base 1. When the chuck 71 holds the welding wire and slides towards the side closer to the feeding device 6, the push block 942 on the chuck 71 actuates the connecting rod assembly 941, causing the connecting rod assembly 941 to push the push block 921 to slide. This causes the actuating assembly 92 to drive the rotating seat 91 to rotate, thereby causing the driven wheel 62 to slide. Thus, the sliding of the chuck 71 triggers the operation of the actuating assembly 92, allowing the end of the welding wire held by the chuck 71 to pass through the positioning vertical plate 82 and through the clearance between the driving wheel 61 and the driven wheel 62, thereby realizing the linkage between the two devices.

[0049] See Figure 5 The reset assembly 93 includes a fixed vertical plate 931 disposed on the front side of the fixed base 1, a first shaft 932 for connecting the driven wheel 62, a second shaft 933 connecting the fixed vertical plate 931 towards the driven wheel 62, and a reset spring 934 for connecting the first shaft 932 and the second shaft 933. In this embodiment, the first shaft 932, the reset spring 934, and the second shaft 933 are fixedly connected in sequence. When the rotating seat 91 is rotated by the actuating assembly 92, the driven wheel 62 is moved, thereby compressing the reset spring 934. When the toggle block 921 is released, the reset spring 934 drives the driven wheel 62 to reset, thereby realizing the reset of the driven wheel 62 and the toggle block 921.

[0050] The implementation principle of the automatic feeding device for a soldering machine in this application embodiment is as follows:

[0051] When the automatic feeding device of the soldering machine is used to feed the solder wire, the end of the solder wire wound on the rotating drum is pulled off by the wire pulling device 3, and the end of the pulled-off solder wire is fixed through the positioning device 4 to fix the solder wire, thereby positioning the solder wire. Then, the solder wire passing through the positioning device 4 is clamped and transported to the vicinity of the feeding device 6 by the clamping device 7. The first driving component is activated, and the first driving component drives the driving wheel 61 to rotate, thereby driving the driven wheel 62 to clamp the end of the solder wire for feeding, thereby realizing the automatic feeding of the solder wire.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
