[0037] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings. The drawings show the preferred embodiments of the present application.

[0038] Reference is made to Figure 1A copper wire cutting mechanism 10, comprising a machine table 100, a wire releasing device 200, a straightening device 300, a wire moving device 400 and a cutting device 500. It is to be noted that the wire releasing device 200 is installed adjacent to the machine table 100, the straightening device 300, the wire moving device 400 and the cutting device 500 are all installed on the machine table 100, wherein the wire releasing device 200 is used to release the copper wire, the straightening device 300 is used to straighten the released copper wire, the wire moving device 400 is used to move the copper wire, and the cutting device 500 is used to cut the straightened copper wire.

[0039] Referring to Figure 1 The wire releasing device 200 comprises a wire releasing frame 210, a wire releasing driving member 220 and a wire coil 230. The wire releasing frame 210 is arranged adjacent to the machine table 100, the wire releasing driving member 220 is arranged on the wire releasing frame 210, and the wire coil 230 is arranged on the output shaft of the wire releasing driving member 220. The wire releasing driving member 220 is used to drive the wire coil 230 to rotate, so as to release the copper wire on the wire coil 230.

[0040] It is to be noted that the wire releasing frame 210 is installed adjacent to the machine table 100, and the distance between the wire releasing frame 210 and the machine table 100 is adjusted according to actual needs. The wire releasing driving member 220 is installed on the wire releasing frame 210, and the wire coil 230 is detachably installed on the wire releasing driving member 220. Thus, the wire coil 230 is continuously driven to rotate by the wire releasing driving member 220, so that the copper wire wound on the wire coil 230 is released in an orderly manner, and the released copper wire is pulled and moved to the next straightening device 300.

[0041] Referring to Figure 1 and Figure 2 The straightening device 300 comprises a straightening driving member 310 and a straightening member 320. The straightening member 320 is rotatably arranged on the machine table 100, the straightening driving member 310 is connected with the straightening member 320, and the straightening driving member 310 is used to drive the straightening member 320 to rotate, so as to straighten the copper wire passing through the straightening member 320.

[0042] It is to be noted that the straightening driving member 310 is installed on the machine table 100, the straightening member 320 is rotatably installed on the machine table 100 through a bearing, and the straightening member 320 is connected with the output shaft of the straightening driving member 310. The straightening member 320 is continuously driven to rotate by the straightening driving member 310, so that the copper wire passing through the straightening member 320 is effectively straightened.

[0043] Referring to Figure 1The wire moving device 400 comprises a wire moving driving member 410, a wire moving slider 420 and a wire moving clamp 430. The wire moving slider 420 is slidingly arranged on the machine table 100 and is located at a side of the straightening member 320 away from the wire feeding device 200. The wire moving driving member 410 is arranged on the machine table 100 and the output shaft of the wire moving driving member 410 is connected with the wire moving slider 420. The wire moving clamp 430 is arranged on the wire moving slider 420. The wire moving driving member 410 is used to drive the wire moving slider 420 to reciprocally slide, so that the wire moving clamp 430 clamps the copper wire when the wire moving slider 420 slides away from the straightening device 300.

[0044] It should be noted that the wire moving slider 420 is slidingly arranged on the machine table 100 and the sliding direction of the wire moving slider 420 is consistent with the threading direction of the straightening member 320. The wire moving slider 420 can be arranged on the machine table 100 through a slide rail or a slide groove is formed on the machine table 100 and the wire moving slider 420 is arranged in the slide groove, so that the wire moving slider 420 can slide along the slide groove, i.e. relative to the machine table 100. The wire moving driving member 410 is arranged on the machine table 100 and is connected with the wire moving slider 420. The wire moving driving member 410 drives the wire moving slider 420 to reciprocally slide on the machine table 100. When the wire moving slider 420 slides away from the straightening member 320, the wire moving clamp 430 clamps the copper wire. When the wire moving slider 420 slides close to the straightening member 320, the wire moving clamp 430 releases the copper wire. In this way, the copper wire can be periodically moved by a certain distance with the reciprocally sliding of the wire moving slider 420, so as to achieve the purpose of automatic material moving.

[0045] Referring to Figure 1 The cutting device 500 comprises a wire feeding head 510, a linkage member 520 and a cutter 530. The wire feeding head 510 is arranged on the machine table 100 and the wire feeding head 510, the wire moving clamp 430 and the straightening member 320 are distributed along the same straight line. The cutter 530 is slidingly arranged on the machine table 100 and is located at a side of the wire feeding head 510 away from the wire moving clamp 430. The linkage member 520 is connected with the cutter 530 and the wire moving driving member 410 respectively. The wire moving driving member 410 is also used to drive the cutter 530 to reciprocally move, so that the cutter 530 cuts the copper wire extending from the wire feeding head 510.

[0046] It should be noted that the wire outlet head 510 is installed on the machine table 100, so that the copper wire passes through the wire moving clamp 430 and is pulled out from the wire outlet head 510. The cutter 530 is slidingly installed on the machine table 100, and the cutter 530 is installed adjacent to the wire outlet head 510. The linkage 520 is connected with the cutter 530 and the wire moving driving member 410 respectively. In this way, the wire moving driving member 410 drives the wire moving slider 420 to reciprocate, and at the same time, the wire moving driving member 410 also drives the cutter 530 to slide, so that the cutter 530 cyclically performs a transverse cutting operation from one end of the wire outlet head 510. Thus, as the wire moving clamp 430 pulls out the copper wire from the wire outlet head 510, the cutter 530 will cut off the wire outlet head 510. By automatically cutting the copper wire, compared with the traditional manual feeding mode, the copper wire cutting efficiency and cutting quality can be effectively improved, so that the subsequent controller circuit welding will not have problems such as uneven length of copper wire or excessive bending, and virtual welding caused by copper wire warping.

[0047] Referring to Figure 1 Optionally, the wire releasing driving member 220 comprises a wire releasing motor 221 and a wire releasing shaft 222. The wire releasing shaft 222 is rotatably arranged on the wire releasing frame 210. The wire releasing motor 221 is arranged on the wire releasing frame 210, and the wire releasing motor 221 is connected with the wire releasing shaft 222. The wire roll 230 is sleeved on the wire releasing shaft 222.

[0048] It should be noted that the wire releasing shaft 222 is rotatably installed on the wire releasing frame 210, for example, the wire releasing shaft 222 is installed through a bearing, so that the wire releasing shaft 222 rotates relative to the wire releasing frame 210, and the axis of the wire releasing shaft 222 is parallel to the horizontal direction. The wire releasing motor 221 is installed on the wire releasing frame 210, and the wire releasing motor 221 is connected with the wire releasing shaft 222, for example, the output shaft of the wire releasing motor 221 is directly fixedly connected with the wire releasing shaft 222, or is connected through a belt in a transfer mode. In this way, the wire releasing shaft 222 can be continuously rotated. The wire roll 230 is fixed on the wire releasing shaft 222.

[0049] Referring to Figure 1 and Figure 3 Optionally, the wire releasing driving member 220 further comprises a top holding block 223 and a clamping block 224. The top holding block 223 is arranged on the wire releasing shaft 222, and the clamping block 224 is screwed on the wire releasing shaft 222. The clamping block 224 is used to clamp the wire roll 230 together with the top holding block 223.

[0050] It should be noted that the top holding block 223 is fixedly installed on the wire releasing shaft 222, for example, the top holding block 223 and the wire releasing shaft 222 can be an integrally formed structure, or can be locked and fixed by using a screw. The clamping block 224 and the wire releasing shaft 222 are in a screwing structure, so that the wire roll 230 is clamped together by the clamping block 224 and the top holding block 223. In an embodiment, the clamping block 224 and the top holding block 223 are both circular structures.

[0051] Referring to Figure 3 Optionally, the top holding block 223 is provided with a first clamping needle 225 on a side surface close to the clamping block 224.

[0052] It should be noted that in order to improve the integrity between the wire coil 230 and the wire releasing shaft 222, and avoid slipping phenomenon between them, the first clamping needle 225 is arranged on the top holding block 223, and when the clamping block 224 and the top holding block 223 jointly clamp the wire coil 230, the first clamping needle 225 is partially inserted into one side of the shell of the wire coil 230.

[0053] Optionally, a plurality of first clamping needles 225 are arranged, and each first clamping needle 225 is circumferentially distributed around the wire releasing shaft 222.

[0054] It should be noted that in order to improve the fixing effect of the wire coil 230, a plurality of first clamping needles 225 are arranged, and each first clamping needle 225 is circumferentially distributed around the wire releasing shaft 222. For example, the number of first clamping needles 225 is 4-8.

[0055] Optionally, the first clamping needle 225 is a pyramid structure. For example, the first clamping needle 225 is a quadrangular pyramid structure, so that the fixing effect of the first clamping needle 225 on the shell of the wire coil 230 can be improved.

[0056] Referring to Figure 3 Optionally, the wire releasing driving member 220 further comprises a pressing and clamping block 226, the pressing and clamping block 226 is sleeved on the wire releasing shaft 222, and the clamping block 224 is used for frictionally connecting with the pressing and clamping block 226, so that the pressing and clamping block 226 and the top holding block 223 jointly clamp the wire coil 230.

[0057] It should be noted that the pressing and clamping block 226 is sleeved on the wire releasing shaft 222, and the pressing and clamping block 226 abuts against the wire coil 230 after being pushed by the clamping block 224. The pressing and clamping block 226 and the clamping block 224 are frictionally connected, so that when the clamping block 224 is screwed and tightened relative to the wire releasing shaft 222, the pressing and clamping block 226 is pushed and clamped by the top holding block 223 to clamp the wire coil 230. Compared with the clamping block 224 directly contacting the wire coil 230, the fixing effect of the wire coil 230 can be effectively improved.

[0058] Optionally, the pressing and clamping block 226 is provided with a second clamping needle on a side surface close to the top holding block 223.

[0059] It should be noted that in order to further improve the fixing effect on the wire coil 230, a second clamping pin is arranged on the pressing block 226, wherein the second clamping pin is arranged opposite to the first clamping pin 225 to clamp the two ends of the wire coil 230 respectively. For example, a plurality of second clamping pins are arranged, and each second clamping pin is distributed around the four sides of the wire releasing shaft 222. In an embodiment, the structure of the second clamping pin is identical to that of the first clamping pin 225.

[0060] Referring to Figure 4 Optionally, the pressing block 226 is provided with a first inclined tooth 228 on the side close to the clamping block 224, and the clamping block 224 is provided with a second inclined tooth 229 on the side close to the pressing block 226, the first inclined tooth 228 and the second inclined tooth 229 abut each other, and the direction of the first inclined tooth 228 is opposite to that of the second inclined tooth 229.

[0061] It should be noted that in order to increase the pressing effect of the clamping block 224 on the pressing block 226, the first inclined tooth 228 is arranged on the pressing block 226, and the second inclined tooth 229 is arranged on the clamping block 224, so that the first inclined tooth 228 and the second inclined tooth 229 abut each other. The directions of the first inclined tooth 228 and the second inclined tooth 229 are opposite to each other, so that when the clamping block 224 is tightened and fixed in place, the fixing effect on the wire coil 230 can be improved, and the problem of loosening can be avoided. It should be noted that the wire releasing driving member 220 can be compatible with wire releasing operation on wire coils 230 of different sizes.

[0062] In an embodiment, a plurality of first inclined teeth 228 are arranged, and a plurality of second inclined teeth 229 are arranged, and each first inclined tooth 228 and each second inclined tooth 229 abut each other. In this way, the clamping stability between the pressing block 226 and the clamping block 224 can be improved.

[0063] Referring to Figure 2 and Figure 5Optionally, the straightening member 320 comprises a straightening roller 321 and a plurality of threading members 322. The straightening roller 321 is rotationally arranged on the machine table 100. The straightening roller 321 is provided with a threading hole 3211 along an axial direction. The straightening roller 321 is provided with a positioning hole 3212 along a radial direction. The positioning hole 3212 is in communication with the threading hole 3211. Each of the threading members 322 is adjustably arranged on the straightening roller 321. In any of the threading members 322, the threading member 322 comprises a fixing ring 3221, a fixing screw 3222, a threading block 3223, and two positioning screws 3224. The fixing ring 3221 is sleeved on an outer sidewall of the straightening roller 321. The fixing screw 3222 is screwed with the fixing ring 3221. The fixing screw 3222 is in abutment with the straightening roller 321. The two positioning screws 3224 are respectively screwed with the fixing ring 3221. The two positioning screws 3224 are both rotationally connected with the threading block 3223. The threading block 3223 is located in the positioning hole 3212. The two positioning screws 3224 are used to jointly clamp the threading block 3223.

[0064] It should be noted that the copper wire can be straightened after passing through the straightening member 320. Specifically, the straightening roller 321 is rotationally mounted on the machine table 100 by a bearing. The straightening roller 321 is provided with the threading hole 3211 along an axial direction. The copper wire passes through the threading hole 3211. Each of the threading members 322 is adjustably arranged on the straightening roller 321. Specifically, the fixing ring 3221 is sleeved on the straightening roller 321. The fixing screw 3222 is screwed with the fixing ring 3221. When the fixing screw 3222 is tightened, the fixing screw 3222 is in abutment with the straightening roller 321, thereby fixing the fixing ring 3221 on the straightening roller 321. In an embodiment, two fixing screws 3222 are provided. The two fixing screws 3222 are respectively located on two radial sides of the fixing ring 3221 in a circumferential symmetry. The two positioning screws 3224 are also screwed on the two radial sides of the fixing ring 3221 in a circumferential symmetry, for example, the two positioning screws 3224 are distributed at equal angles with the two fixing screws 3222 on the outer periphery of the fixing ring 3221. The threading block 3223 is located in the positioning hole 3212. The two positioning screws 3224 are both rotationally connected with the threading block 3223. In this way, by adjusting the position of the positioning screw 3224 relative to the fixing ring 3221, the depth of the threading block 3223 in the positioning hole 3212, that is, the radial position of the threading block 3223 relative to the straightening roller 321, can be adjusted. Further, the copper wire passes through each of the threading blocks 3223. In this way, when the straightening roller 321 rotates to drive the rotation of each of the threading members 322, the copper wire passing through can be straightened. By setting the threading block 3223 as an adjustably-positioned structure, the equipment can be easily adjusted to quickly set the straightening parameters of the copper wire.

[0065] In one embodiment, the straightening driving member 310 is a motor-driven belt assembly, in which the belts are respectively sleeved with the motor and the straightening roller 321, so that the straightening roller 321 can be continuously driven to rotate. Further, the straightening driving member 310 can also be a motor-driven speed reducer structure.

[0066] Referring to Figure 1 and Figure 6 Optionally, the wire shifting clamp 430 includes a bearing block 431, a pressing block 432, a tension spring 433, and two stop blocks 434. The bearing block 431 is arranged on the wire shifting slider 420, the pressing block 432 is rotationally arranged on the wire shifting slider 420, the two ends of the tension spring 433 are respectively connected with the pressing block 432 and the bearing block 431, the tension spring 433 is used to drive the pressing block 432 to rotate, so that one end of the pressing block 432 abuts against one end of the bearing block 431, and the two stop blocks 434 are respectively arranged on the machine table 100. When the wire shifting slider 420 reciprocates, one of the two stop blocks 434 pushes the pressing block 432 to rotate.

[0067] It should be noted that the bearing block 431 is mounted on the wire shifting slider 420, and the bearing block 431 is mounted in the horizontal direction. The pressing block 432 is rotationally mounted on the wire shifting slider 420, for example, the middle part of the pressing block 432 is connected with the wire shifting slider 420, so that when the pressing block 432 rotates, one end of the pressing block 432 abuts against one end of the bearing block 431. The two ends of the tension spring 433 are respectively connected with the pressing block 432 and the bearing block 431, so that under the elastic tension of the tension spring 433, one end of the pressing block 432 always abuts against one end of the bearing block 431. The two stop blocks 434 are respectively mounted on the machine table 100, and the two stop blocks 434 are located at the front and rear ends of the sliding direction of the wire shifting slider 420. When the wire shifting slider 420 slides to the limit position on one side, the stop block 434 on that side pushes the pressing block 432, so that the pressing block 432 rotates to the other side. In this way, the wire shifting slider 420 and the two stop blocks 434 cooperate to enable the pressing block 432 to clamp or release the copper wire.

[0068] Further, for the convenience of description, the rotation center of the pressing block 432 is defined as the center line, the side of the pressing block 432 close to the straightening roller 321 is defined as the wire inlet side, and the side of the pressing block 432 away from the straightening roller 321 is defined as the wire outlet side. Under the elastic tension of the tension spring 433, either the pressing block 432 and the bearing block 431 abut against each other at the end of the wire inlet side, or the pressing block 432 and the bearing block 431 abut against each other at the end of the wire outlet side.

[0069] Specifically, when the wire shifting slider 420 slides close to the straightening roller 321, the pressing block 432 and the bearing block 431 at the end of the wire inlet side abut against each other, at this time, the copper wire is released from being clamped between the pressing block 432 and the bearing block 431, when the wire shifting slider 420 is about to slide to the limit position close to the straightening roller 321, the pressing block 432 is pushed and limited by the stop block 434 at the wire inlet side, so that the pressing block 432 rotates clockwise, so that the abutment between the pressing block 432 and the bearing block 431 at the end of the wire inlet side changes to the abutment between the pressing block 432 and the bearing block 431 at the end of the wire outlet side, at this time, the copper wire is clamped between the pressing block 432 and the bearing block 431 at the end of the wire outlet side. At this time, when the wire shifting slider 420 slides away from the straightening roller 321, the copper wire is moved forward. When the wire shifting slider 420 is about to slide to the limit position away from the straightening roller 321, the pressing block 432 is pushed and limited by the stop block 434 at the wire outlet side, so that the pressing block 432 rotates counterclockwise, so that the abutment between the pressing block 432 and the bearing block 431 at the end of the wire outlet side changes to the abutment between the pressing block 432 and the bearing block 431 at the end of the wire inlet side, at this time, the copper wire is released. Then, the wire shifting slider 420 slides close to the straightening roller 321 to enter the next cycle period. In this way, the copper wire is periodically transferred in a single direction.

[0074] It should be noted that the clamping block 4421 and the line setting base 441 can be clamped and fixed by tightening the clamping screw 4423. The distance between the two rollers 4422 can be adjusted through the clamping groove 4411, so that it can be suitable for copper wires of different diameters.

[0075] Referring to Figure 1 , Figure 6 and Figure 8 Optionally, the wire moving driving member 410 comprises a wire moving motor 411, a main shaft 412, an eccentric disc 413 and a swing arm 414, the wire moving motor 411 is arranged on the machine table 100, the main shaft 412 is rotatably arranged on the machine table 100 and connected with the wire moving motor 411, the eccentric disc 413 is arranged on the main shaft 412, and the swing arm 414 is rotatably connected with the eccentric disc 413 and the wire moving sliding block 420.

In order to facilitate the adjustment of the length of the copper wire, the above structure is provided. Specifically, the eccentric groove 4131 is formed on the eccentric disc 413, for example, the eccentric groove 4131 is a T-shaped groove structure, and the extension direction of the eccentric groove 4131 is consistent with the radial direction of the eccentric disc 413. The positioning screw 4155 is fixedly installed at the bottom of the eccentric groove 4131, and the axial direction of the positioning screw 4155 is consistent with the radial direction of the eccentric disc 413. The eccentric distance of the swing arm 414 on the eccentric disc 413 is determined by the number of the pad block 4154. When it is needed to increase the eccentric distance, the pad block 4154 is increased, and when it is needed to reduce the eccentric distance, the pad block 4154 is correspondingly reduced. In this way, the eccentric distance of the adapter block 4151 is changed by changing the number of the pad block 4154, which facilitates the replacement and maintenance of the equipment. Further, after the pad block 4154 and the adapter block 4151 are both installed on the positioning screw 4155, the adapter block 4151 and the eccentric disc 413 are fixed as a whole by the screwing of the tightening bolt 4152 on the positioning screw 4155.

[0080] It should be noted that the main shaft 412 is used to drive the eccentric disc 413 to rotate, and is also used to drive the cutter 530 to slide through the linkage 520, so as to cut the copper wire.
