[0039] Now, various exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present application.

[0040] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way a limitation on the present application, its application or use.

[0041] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods and devices should be regarded as part of the specification.

[0042] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0043] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0044] First, it should be noted that the X - direction, Y - direction and Z - direction mentioned in the embodiments of the present application refer to the directions marked in the attached Figure 1 and Figure 2 drawings. Among them, the X - direction, Y - direction and Z - direction intersect pairwise.

[0045] As Figures 1 - 8As shown, according to the first aspect of the embodiments of the present application, a wire feeding system 100 is provided, which includes an unwinding mechanism 1, an active buffer mechanism 2, and a passive buffer mechanism 3. The unwinding mechanism 1 includes a first mounting plate 11, a plurality of second mounting plates 12, and a plurality of unwinding components 13. One of the unwinding components 13 is provided on one of the second mounting plates 12, and the plurality of second mounting plates 12 are provided on the first mounting plate 11. The second mounting plate 12 is detachably connected to the first mounting plate 11. The passive buffer mechanism 3 is provided downstream of the unwinding mechanism 1, and the passive buffer mechanism 3 is used to passively buffer a section of wire. The active buffer mechanism 2 is provided downstream of the passive buffer mechanism 3, and the active buffer mechanism 2 is used to passively buffer a section of wire.

[0046] In the prior art, each part of the unwinding component 13 is usually directly installed on a mounting plate. For the part that needs to be operated on the back of the mounting plate during repair or maintenance, the repair is relatively difficult and time-consuming and laborious.

[0047] The embodiments of the present application provide a wire feeding system 100, which is used to convey wire to the welding device of a welding equipment.

[0048] As Figure 1 and Figure 2 shown, the unwinding mechanism 1 includes a first mounting plate 11, a plurality of second mounting plates 12, and a plurality of unwinding components 13. Among them, the unwinding component 13 is configured to place a coil. One unwinding component 13 is correspondingly installed on one second mounting plate 12 to form an unwinding module, and then the second mounting plate 12 is installed on the first mounting plate 11. When one of the unwinding components 13 needs to be repaired or inspected, only the corresponding second mounting plate 12 needs to be removed from the first mounting plate 11. The repair is relatively convenient, which can improve the efficiency of repair or maintenance and will not affect the operation of other unwinding components 13 on the first mounting plate 11.

[0049] Further, a plurality of second mounting plates 12 are arranged on the first mounting plate 11. The plurality of second mounting plates 12 can be arranged at intervals on the first mounting plate 11. That is to say, there is a certain gap between adjacent two second mounting plates 12 to facilitate the installation of the second mounting plate 12. The plurality of second mounting plates 12 can also be arranged in sequence on the first mounting plate 11. That is to say, there is no gap between adjacent two second mounting plates 12, so that more second mounting plates 12 can be installed on the first mounting plate 11. Among them, the plurality of second mounting plates 12 can be distributed in multiple rows and multiple columns on the first mounting plate 11.

[0050] As Figure 1 、 Figure 2 and Figure 8As shown, the wire feeding system 100 further includes a passive buffer mechanism 3, and the passive buffer mechanism 3 is arranged downstream of the unwinding mechanism 1. In other words, the wire in the unwinding mechanism 1 passes through the passive buffer mechanism 3; when stretching the wire, the passive buffer mechanism 3 can buffer a section of the wire for wire stretching, which can prevent the wire from falling off the wire passing wheel during the stretching process and can prevent the wire from being broken.

[0051] As Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the wire feeding system 100 further includes an active buffer mechanism 2. The active buffer mechanism 2 is located downstream of the passive buffer mechanism 3. The wire of the coil in the unwinding mechanism 1 first passes through the passive buffer mechanism 3 and then passes through the active buffer mechanism 2 and is conveyed to the welding device; when stretching the wire, the active buffer mechanism 2 buffers a section of the wire for wire stretching. That is to say, the wire is in a relaxed state. When stretching the wire, the working efficiency is improved, and the force required to stretch the wire becomes smaller. It can prevent the wire from falling off the wire passing wheel and can prevent the wire from being broken.

[0052] It should be noted that the upstream and downstream mentioned in this application are corresponding, and the upstream and downstream refer to the front-back relationship of wire conveying; for example, the passive buffer mechanism 3 is located downstream of the unwinding mechanism 1, and the active buffer mechanism 2 is located downstream of the passive buffer mechanism 3 means that along the wire conveying direction, the unwinding mechanism 1, the passive buffer mechanism 3, and the active buffer mechanism 2 are arranged in sequence, and the wire is conveyed from the unwinding mechanism 1 to the passive buffer mechanism 2 and the active buffer mechanism 2 in sequence.

[0053] In an optional implementation manner, the unwinding assembly 13 includes a driving member 131 and a mounting rod 132. The mounting rod 132 is connected to the driving end of the driving member 131, and the driving member 131 is arranged on the second mounting plate 12; the first mounting plate 11 is provided with a plurality of through holes 111, and the mounting rod 132 of each unwinding assembly 13 passes through the corresponding through hole 111, and the mounting rod 132 and the driving member 131 are respectively located on both sides of the first mounting plate 11 in the Y direction.

[0054] As Figure 1 and Figure 2As shown, the unwinding assembly 13 includes a driving member 131 and a mounting rod 132. Among them, the mounting rod 132 is used to place the material roll. The driving member 131 is mounted on the second mounting plate 12, and the mounting rod 132 is connected to the driving end of the driving member 131. The driving member 131 can drive the mounting rod 132 to rotate around its own axis, so as to drive the material roll to rotate, thereby realizing the feeding. A plurality of through holes 111 are formed in the first mounting plate 11. One unwinding assembly 13 is correspondingly mounted at each through hole 111. The mounting rod 132 of the unwinding assembly 13 passes through the corresponding through hole 111. The mounting rod 132 and the driving member 131 are respectively located on both sides of the first mounting plate 11 in the Y direction. The second mounting plate 12 is fixed to the first mounting plate 11.

[0055] By forming the through holes 111 in the first mounting plate 11, it is convenient to mount the unwinding assembly 13 on the first mounting plate 11.

[0056] Among them, the driving member 131 can adopt a motor.

[0057] In an alternative embodiment, the unwinding assembly 13 further includes a clamping member 4. The mounting rod 132 is used to place the material roll. The clamping member 4 is sleeved on the circumferential direction of the mounting rod 132 to limit the axial movement of the material roll along the mounting rod 132. The clamping member 4 can restrict the axial movement of the material roll on the mounting rod 132 in the circumferential direction of the mounting rod 132.

[0058] In an alternative embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the clamping member 4 includes a first connecting portion 41. The first connecting portion 41 includes a fixing portion 411, a pressing portion 412 and a locking portion 413. The fixing portion 411 is provided with a first hole 4111, and the locking portion 413 is provided with a second hole 4131. The pressing portion 412 and the locking portion 413 are connected by a first elastic member 414 in the radial direction of the first hole 4111. When the pressing portion 412 is pressed, the first elastic member 414 is compressed, and the axes of the first hole 4111 and the second hole 4131 coincide, enabling the mounting rod 132 to pass through the first hole 4111 and the second hole 4131. When the pressing portion 412 is released, the first elastic member 414 returns to its normal state, and the axes of the first hole 4111 and the second hole 4131 are parallel. Among them, the axial direction of the first hole 4111 and the axial direction of the second hole 4131 are the Y direction, that is, the first hole 4111 and the second hole 4131 are staggered, and the locking portion 413 will abut against the outer wall of the mounting rod 132, thereby restricting the movement of the material roll in the axial direction of the mounting rod 132.

[0059] In an alternative embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the clamping part 4 further includes a second connecting part 42. A third hole 421 is formed in the second connecting part 42. The first hole 4111 and the second hole 4131 are concentrically arranged. A second elastic member 43 is arranged between the first connecting part 41 and the second connecting part 42 along the axial direction of the first hole 4111. The second connecting part 42 can compress the second elastic member 43 along the axial direction of the first hole 4111. A limiting groove 1321 is formed on the outer wall of the mounting rod 132, and the locking part 413 can be clamped in the limiting groove 1321. According to the axial length of the coil, that is, the length of the coil in the Y direction, by compressing the second elastic member 43 along the axis of the first hole 4111 through the second connecting part 42, the locking part 413 can be clamped in the limiting groove 1321.

[0060] In an optional embodiment, the unwinding mechanism 1 further includes a detection component 14. The detection component 14 is arranged on the first mounting plate 11. The detection component 14 is arranged adjacent to the unwinding component 13, and the detection component 14 is configured to detect the remaining amount of the coil.

[0061] As Figure 1 shown, the unwinding mechanism 1 further includes a detection component 14. Among them, the detection component 14 is arranged on the first mounting plate 11 and close to the unwinding component 13. The unwinding component 13 is used to place the coil and feed the coil. The detection component 14 can detect the remaining amount of the coil to control the rotation speed of the coil through the driving member 131. For example, if the remaining amount of the coil is large, the outer diameter of the coil is large. At this time, the length of the welding wire released when the coil rotates one circle is H1; if the remaining amount of the coil is small, the outer diameter of the coil is small. At this time, the length of the welding wire released when the coil rotates one circle is H2, and H1 is greater than H2. Therefore, when the remaining amount of the coil is different in the same time, the length of the welding wire released is different. Therefore, by setting the detection component 14 to detect the remaining amount of the coil, the feeding amount can be controlled.

[0062] Further, the detection component 14 can adopt a CCD camera or a laser detector.

[0063] In an optional embodiment, the active buffer mechanism 2 includes at least one sliding roller assembly and a driving component 22. The driving component 22 can drive the sliding roller assembly to move for buffering a section of welding wire.

[0064] As Figure 6 and Figure 7As shown, in one embodiment, the active buffer mechanism 2 has a sliding roller assembly as the first roller assembly 21. Among them, the first roller assembly 21 is a wire passing wheel, and the welding wire bypasses the outer periphery of the first roller assembly 21 from below the first roller assembly 21, or the welding wire can bypass the outer periphery of the first roller assembly 21 from above the first roller assembly 21; if the welding wire bypasses the outer periphery of the first roller assembly 21 from above, when the driving assembly 22 drives the first roller assembly 21 to move, the welding wire will gradually be in a slack state, which is convenient for stretching the welding wire at this time. When the driving assembly 22 drives the first roller assembly 21 to slowly move downward in the Z direction, the welding wire will gradually be in a tensioned state, which is to prepare for stretching the welding wire at this time. When it is necessary to stretch the welding wire, the driving assembly 22 can drive the first roller assembly 21 to move. This structure is simple, can make the welding wire in a slack state, improves the work efficiency when stretching the welding wire, reduces the force required to stretch the welding wire, can prevent the welding wire from falling off the wire passing wheel, and can prevent the welding wire from being broken.

[0065] In an alternative embodiment, the number of the sliding roller assemblies is two, namely the first roller assembly 21 and the second roller assembly 23 respectively; the active buffer mechanism 2 further includes a third roller assembly 24; in the X direction, the second roller assembly 23 is spaced from the first roller assembly 21, and the third roller assembly 24 is arranged between the first roller assembly 21 and the second roller assembly 23, and the driving assembly 22 can drive the first roller assembly 21 and the second roller assembly 23 to move in the Z direction simultaneously.

[0066] As Figure 6 and Figure 7 As shown, the number of the sliding roller assemblies is two, namely the first roller assembly 21 and the second roller assembly 23 respectively. Among them, in the X direction, the second roller assembly 23 is spaced from the first roller assembly 21, the third roller assembly 24 is located between the first roller assembly 21 and the second roller assembly 23, the third roller assembly 24 is fixedly arranged, and the driving assembly 22 can drive the first roller assembly 21 and the second roller assembly 23 to move in the Z direction simultaneously.

[0067] Further explanation, the welding wire bypasses the first roller assembly 21, the third roller assembly 24 and the second roller assembly 23 in sequence; specifically, in the Z direction, the welding wire bypasses below the first roller assembly 21, above the third roller assembly 24 and below the second roller assembly 23, or the welding wire bypasses above the first roller assembly 21, below the third roller assembly 24 and above the second roller assembly 23. By setting the first roller assembly 21 and the second roller assembly 23, the driving assembly 22 drives the first roller assembly 21 and the second roller assembly 23 to move in the Z direction, so as to improve the buffer capacity of the welding wire.

[0068] In an alternative embodiment, the active buffer mechanism 2 further includes a fourth roller assembly 25, which is arranged on a side of the first roller assembly 21 away from the second roller assembly 23 in the X direction; and / or a fifth roller assembly 26, which is arranged on a side of the second roller assembly 23 away from the first roller assembly 21 in the X direction.

[0069] In one embodiment, the active buffer mechanism 2 further includes a fourth roller assembly 25.

[0070] In another embodiment, the active buffer mechanism 2 further includes a fifth roller assembly 26.

[0071] In another embodiment, the active buffer mechanism 2 includes a fourth roller assembly 25 and a fifth roller assembly 26. Taking this embodiment as an example, as Figure 6 and Figure 7 shown, specifically, the fourth roller assembly 25 is arranged on a side of the first roller assembly 21 away from the second roller assembly 23. That is to say, the welding wire bypasses the fourth roller assembly 25 and the first roller assembly 21 in sequence. By arranging the fourth roller assembly 25, it is convenient to guide the welding wire from the unwinding mechanism 1 to the first roller assembly 21. The fifth roller assembly 26 is arranged on a side of the second roller assembly 23 away from the first roller assembly 21. That is to say, the welding wire bypasses the fourth roller assembly 25, the first roller assembly 21, the third roller assembly 24, the second roller assembly 23 and the fifth roller assembly 26 in sequence. By arranging the fifth roller assembly 26, it is convenient to stretch the welding wire from the active buffer mechanism 2 by the wire stretching mechanism.

[0072] In an alternative embodiment, the active buffer mechanism 2 further includes a first sliding part 27, which is arranged along the Z direction, and the first roller assembly 21 is slidably connected to the first sliding part 27; and / or a second sliding part 28, which is arranged along the Z direction, and the second roller assembly 23 is slidably connected to the second sliding part 28.

[0073] In one embodiment, the active buffer mechanism 2 further includes a first sliding part 27.

[0074] In another embodiment, the active buffer mechanism 2 further includes a second sliding part 28.

[0075] In another embodiment, the active caching mechanism 2 further includes a first sliding portion 27 and a second sliding portion 28. Taking this embodiment as an example for illustration, specifically, the first sliding portion 27 is arranged along the Z direction, and the first roller assembly 21 is slidably connected to the first sliding portion 27. When the driving assembly 22 drives the first roller assembly 21 to move along the Z direction, the first roller assembly 21 will move along the first sliding portion 27 in the Z direction. The first sliding portion 27 provides a guiding function for the first roller assembly 21 and can make the movement of the first roller assembly 21 more stable. The second sliding portion 28 is arranged along the Z direction, the first sliding portion 27 and the second sliding portion 28 are arranged at intervals along the X direction, and the second roller assembly 23 is slidably connected to the second sliding portion 28. When the driving assembly 22 drives the second roller assembly 23 to move along the Z direction, the second roller assembly 23 will move along the second sliding portion 28 in the Z direction. The second sliding portion 28 provides a guiding function for the second roller assembly 23 and can make the movement of the second roller assembly 23 more stable.

[0076] Further explanation, the first sliding portion 27 can be a chute, and the first roller assembly 21 includes a slider, and the slider is slidably connected to the chute; the first sliding portion 27 can be a guide rail, and the first roller assembly 21 includes a slider, and the slider is slidably connected to the guide rail. The second sliding portion 28 can be a chute, and the second roller assembly 23 includes a slider, and the slider is slidably connected to the chute; the second sliding portion 28 can be a guide rail, and the second roller assembly 23 includes a slider, and the slider is slidably connected to the guide rail.

[0077] In an alternative embodiment, the driving assembly 22 includes a motor, a lead screw arranged along the Z direction, a nut seat, and a connecting plate. The lead screw is connected to the output end of the motor, the nut seat is rotatably connected to the lead screw, the connecting plate is connected to the nut seat, the first roller assembly 21 is connected to one end of the connecting plate, and the second roller assembly 23 is connected to the other end of the connecting plate. The motor drives the lead screw to rotate, and the nut seat will move along the Z direction, thereby driving the first roller assembly 21 and the second roller assembly 23 to move along the Z direction.

[0078] In another alternative embodiment, the driving assembly 22 includes a driving wheel 221, a driven wheel 222, a transmission belt 223, and a connecting plate 224. The driving wheel 221 and the driven wheel 222 are arranged at intervals along the Z direction. The transmission belt 223 is sleeved on the driving wheel 221 and the driven wheel 222. The connecting plate 224 is connected to the transmission belt 223. The connecting plate 224 has a first connection end and a second connection end. The first roller assembly 21 and the second roller assembly 23 are connected to the connecting plate 224.

[0079] Such as Figure 6 and Figure 7As shown, the drive assembly 22 includes a driving wheel 221, a driven wheel 222, a transmission belt 223, and a connecting plate 224. The driving wheel 221 and the driven wheel 222 are arranged at intervals in the Z direction. The transmission belt 223 is sleeved on the driving wheel 221 and the driven wheel 222. The connecting plate 224 is connected to the transmission belt 223. The first roller assembly 21 is connected to the first connection end of the connecting plate 224, and the second roller assembly 23 is connected to the second connection end of the connecting plate 224. This structure is simple and easy to install.

[0080] Further explanation, the drive assembly 22 further includes a motor. The output end of the motor is connected to the driving wheel 221. The motor drives the driving wheel 221 to rotate, thereby driving the transmission belt 223 to rotate. Therefore, the first roller assembly 21 and the second roller assembly 23 can move simultaneously in the Z direction.

[0081] In an alternative embodiment, the passive buffer mechanism 3 includes a first sensor 31, a second sensor 32, and a sixth roller assembly 33. The first sensor 31 and the second sensor 32 are arranged at intervals in the Z direction. The sixth roller assembly 33 can move in the Z direction between the first sensor 31 and the second sensor 32.

[0082] As Figure 8 shown, the passive buffer mechanism 3 includes a first sensor 31, a second sensor 32, and a sixth roller assembly 33. Among them, the welding wire is guided to the active buffer mechanism 2 after passing through the sixth roller assembly 33 from the unwinding mechanism 1. The first sensor 31 and the second sensor 32 are arranged at intervals in the Z direction. The sixth roller assembly 33 can move in the Z direction between the first sensor 31 and the second sensor 32. In the Z direction, the first sensor 31 is located above the second sensor 32. When the sixth roller assembly 33 moves in the Z direction and the first sensor 31 detects the sixth roller assembly 33, the unwinding mechanism 1 starts to unwind and feed the material. After the unwinding mechanism 1 unwinds and feeds the material, the sixth roller assembly 33 will move downward in the Z direction under the action of gravity until the second sensor 32 detects the sixth roller assembly 33, and then the unwinding mechanism 1 stops unwinding.

[0083] Figure 8 ​As shown, the passive buffer mechanism 3 further includes a sliding rod 34, and the first sensor 31 and the second sensor 32 are arranged on the sliding rod 34 along the Z direction; the sixth roller assembly 33 includes a connecting rod 331, a sixth wire passing wheel 332, a sliding member 333 and a detection rod 334.
