[0070] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0071] like Figure 1-30 As shown, a winding and welding integrated machine includes a frame 1, a turntable module 2 and a winding module 3 mounted on the frame 1.

[0072] The turntable module 2 includes a turntable 201 rotatably mounted on the frame 1 and a fixed plate 202 fixed on the frame 1 and located directly above the turntable 201. The axis of the turntable 201 is vertically oriented, and the axis of the fixed plate 202 is coaxial with the axis of the turntable 201. The turntable module 2 also includes multiple sets of placement blocks 203 disposed on the edge of the turntable 201. The multiple sets of placement blocks 203 are evenly distributed on the edge of the turntable 201, and each set of placement blocks 203 has two blocks. The two placement blocks 203 are symmetrically arranged with respect to a first line of symmetry. When viewed from above, the first line of symmetry passes through the center of the turntable 201, that is, the first line of symmetry is a diameter of the turntable 201. Each placement block 203 extends along its corresponding first line of symmetry and has an end plate 204 at one end opposite to the axis of the turntable 201. The plane of the end plate 204 is perpendicular to its corresponding first line of symmetry. The upper end of the end plate 204 is higher than the upper surface of the placement block 203. The wound coil 100 is placed on the upper surface of the placement block 203 near the end plate 204. Two first wire grooves 2041 are provided on the end plate 204. The two first wire grooves 2041 open upwards and are arranged along the arrangement direction of the two placement blocks 203. The two ends of the wound coil 100 are placed in the first wire grooves 2041, and the ends of the wires protrude from the first wire grooves 2041.

[0073] A first guide rod 208 is provided at the position for placing the coil 100 on each placement block 203. The first guide rod 208 extends vertically and can move up and down relative to the placement block 203. A buffer block 209 is provided below the two placement blocks 203 in the same group. The lower end of the first guide rod 208 is fixed to the buffer block 209. The buffer block 209 can move up and down. Two buffer springs 210 are provided below the buffer block 209. The upper end of the buffer spring 210 abuts against the lower surface of the buffer block 209. The buffer springs 210 are always in a compressed state, so that the buffer block 209 can abut against the placement block 203 when no external force is applied. When the coil 100 is placed on the placement block 203, the coil 100 is fitted onto the first guide rod 208 to prevent the coil 100 from moving back and forth.

[0074] The winding module 3 comprises three sets, all with identical structures. These three sets can operate simultaneously and are arranged sequentially along the rotation direction of the turntable 201, providing three winding stations for simultaneous winding. The angle between adjacent winding modules 3 and the rotation axis of the turntable 201 is equal to the angle between the welding axes of two adjacent placement blocks 203 and the turntable 201. Each set of winding modules 3 includes a first mounting plate 302 and two clamps 301 mounted on the first mounting plate 302. The arrangement direction of the two clamps 301 is parallel to the arrangement direction of the two placement blocks 203 located at the corresponding winding station. The distance between the clamping jaws of the two clamps 301 is equal to the distance between two placement blocks 203 located in the same group. The first mounting plate 302 is mounted on the frame 1 and can move back and forth within a certain range in the horizontal plane relative to the frame 1.

[0075] Each clamp 301 includes a fixed arm 3012 fixed to a first mounting plate 302 and a movable arm 3011 movably disposed on the first mounting plate 302. The movable arm 3011 can move relative to the first mounting plate 302 along the arrangement direction of the two clamps 301. During the movement, the ends of the fixed arm 3012 and the movable arm 3011 near the turntable 201 can move closer or further apart to close or open the clamp, thereby clamping or releasing the copper wire. Preferably, the two movable arms 3011 on the same winding module 3 are driven by the same drive cylinder 303. A blade 3013 is provided on the end face of the fixed arm 3012 near the turntable 201, which cuts the copper wire simultaneously during the clamping process.

[0076] A conduit 304 is provided on the side opposite to the turntable 201, relative to the corresponding clamp. The conduit 304 extends along its corresponding first line of symmetry, and its height matches the height of the clamp. The copper wire passes through the conduit 304 and the clamp in sequence. The conduit 304 is immovable relative to its corresponding fixed arm 3012.

[0077] The winding module 3 further includes a winding drive assembly 305 and a guide assembly 306. The winding drive assembly 305 includes a first mounting bracket 3051 mounted on the frame 1, a second mounting bracket 3052 movably mounted on the first mounting bracket 3051, and two sets of first rotating assemblies 3053 rotatably mounted on the second mounting bracket 3052. The two sets of first rotating assemblies 3053 are arranged along the arrangement direction of the two clamps, and the distance between the axes of the two sets of first rotating assemblies 3053 is equal to the distance between the two clamps.

[0078] Each set of the first rotating components 3053 includes a first sleeve 30531 rotatably mounted on the second mounting bracket 3052, a first rotating head 30532 mounted on the first sleeve 30531 and capable of rotating with the first sleeve 30531, and a placement platform 30539 mounted on the first rotating head 30532. The lower end of the first rotating head 30532 is inserted into the upper end of the first sleeve 30531. A mounting groove 30534 is provided on the first rotating head 30532, and a top arm 30535 is provided within the mounting groove 30534. The top arm 30535 is L-shaped. A through hole is provided on the portion of the first rotating head 30532 located in the mounting groove 30534, the through hole connecting the mounting groove 30534 with the hollow portion of the first sleeve 30531, and the through hole is coaxially arranged with the first sleeve 30531. The first rotating assembly 3053 further includes a first push rod 30536, which is located in the first sleeve 30531 and coaxially arranged with the first sleeve 30531. The lower end of the first push rod 30536 extends out from the lower end of the first sleeve 30531, and the upper end passes through the through hole and extends into the mounting groove 30534. The lower end of the top arm 30535 abuts against the upper end of the first top rod 30536. A clamping block 305310 is provided at the higher end of the top arm 30535. The placement platform 30539 is located directly above the lower portion of the top arm 30535 and to one side of the higher portion. The clamping block 305310 is closer to the placement platform 30539 than the top arm 30535. A stop block 305311 is provided on one side of the placement platform 30539, allowing the clamping block 305310 to selectively press against the stop block 305311. The top arm 30535 is rotatably mounted on the first rotating head 30532 via a connecting rod 305313. The first top rod 30536 can move up and down relative to the first sleeve 30531, thereby pushing the top arm 30535 to rotate within a certain range around the axis of the connecting rod 305313. This causes the upper end of the top arm 30535 to drive the clamping block 305310 to move back and forth, allowing the clamping block 305310 to press against or disengage from the stop block 305311. When the clamping block 305310 presses against the stop block 305311, it can clamp the copper wire. Preferably, a wire clamping groove is provided on the side of the clamping block 305310 facing the stop block 305311 to better clamp the copper wire. During the winding process, the clamp 301 holds the end of the copper wire and moves it toward the corresponding first rotating head 30532 and passes over the first rotating head 30532. Then the clamping block 305310 clamps the copper wire, the clamp 301 is released, and the first rotating component 3053 starts to rotate to perform the winding.

[0079] A limiting rod 30537 is provided near the top of the first push rod 30536. The limiting rod 30537 is perpendicular to the axis of the first push rod 30536. A limiting groove 305314 is provided on the first rotating head 30532 at a position corresponding to the limiting rod 30537. The limiting groove 305314 communicates with the mounting grass 30534 and extends vertically. Both ends of the limiting rod 30537 are inserted into the corresponding limiting grooves 305314 and can slide within the size range of the limiting grooves 305314 in the vertical direction. The cooperation of the limiting rod 30537 and the limiting groove 305314 can limit the range of movement of the first push rod 30536 in the vertical direction.

[0080] A first pull rod 305315 is provided on the higher part of the top arm 30535, and a second pull rod 305316 is provided on the first rotating head 30532 on the side opposite to the first pull rod 305315. The first pull rod 305315 and the second pull rod 305316 are parallel and both are parallel to the connecting rod 305313. Two tension springs 305312 are provided between the first pull rod 305315 and the second pull rod 305316. The tension springs 305312 are always in a stretched state so that the top arm 30535 can always be pressed against the stop block 305311 when the force of the first top rod 30536 is lost.

[0081] A pulley 30533 is provided on the first sleeve 30531, and a motor is provided on the second mounting bracket 3052. The motor is connected to the pulley 30533 via a belt, thereby driving the first sleeve 30531 and other structures on the first sleeve 30531 to rotate together.

[0082] Furthermore, a first top block 305317 is provided on the second mounting bracket 3052 and directly below each first top rod 30536. Under the action of the tension spring 305312, the lower end of the first top rod 30536 always abuts against the first top block 305317. The first top block 305317 can move up and down. When it is necessary to loosen the copper wire, the first top block 305317 pushes the first top rod 30536 upward, and the first top rod 30536 drives the top arm 30535 to rotate, thereby disengaging the clamping block 305310 from the stop block 305311. The first top block 305317 is driven by a cylinder.

[0083] The guide assembly 306 includes a support rod 3061 mounted on the frame 1, a third mounting bracket 3062 supported on the support rod 3061, a fourth mounting bracket 3063 movably supported below the third mounting bracket 3062, and two second rotating assemblies mounted on the fourth mounting bracket 3063. Each second rotating assembly includes a second sleeve 3065 rotatably mounted on the fourth mounting bracket 3063, a second rotating head 3066 located at the lower end of the second sleeve 3065, and a second push rod 3067 located inside the second sleeve 3065. The second rotating head 3066 is coaxially mounted with the second sleeve 3065, and the second push rod 3067 is coaxially mounted with the second sleeve 3065. The upper end of the second push rod 3067 extends from the upper end of the second sleeve 3065, and the lower end extends from the second rotating head 3066. The second push rod 3067 is movable up and down relative to the second sleeve 3065. The distance between the axes of the second push rods 3067 of the two second rotating assemblies is equal to the distance between the axes of the two first push rods 30536. The diameter of the lower end of the second push rod 3067 is equal to or slightly smaller than the inner diameter of the coil 100.

[0084] When winding is required, the second push rod 3067 extends a certain length from the lower end of the second rotating head 3066, the fourth mounting bracket 3063 moves downward, the second mounting bracket 3052 moves upward, and the upper end of the first push rod 30536 contacts the lower end of the corresponding second push rod 3067. At the start of winding, the first rotating assembly 3053 and the second rotating assembly rotate in the same direction and at the same speed. Because the end of the copper wire is pressed against the stop block 305311 by the clamping block 305310, the end of the copper wire will rotate along with the first rotating assembly, allowing the copper wire to wind onto the portion of the second push rod 3067 extending from the second rotating head 3066. Furthermore, during the winding process, the coil has a certain height in the vertical direction; therefore, the second mounting bracket 3052 and the fourth mounting bracket 3063 need to move up and down synchronously. In fact, the coil 100 has two layers, with the inner layer wound first and then the outer layer wound. After one coil 100 is wound, the clamp 301 is moved to clamp the copper wire between the coil 100 and the conduit 304 and cut the copper wire at the same time.

[0085] A second top block 3068 is provided on the fourth mounting bracket 3063 at a position corresponding to each second top rod 3067. The second top block 3068 is movable up and down, and the upper end of the second top rod 3067 abuts against the second top block 3068, thereby driving the second top rod 3067 to move up and down. Preferably, a bearing can be provided at the upper end of the second top rod 3067, and the bearing is fixed to the second top block 3068 to reduce friction between the second top rod 3067 and the second top block 3068. The second top rod 3067 is driven by a cylinder.

[0086] Furthermore, an air-blowing pipe 3064 is provided on the fourth mounting bracket 3063 at a position corresponding to each of the second rotating components. The air-blowing pipe 3064 blows air towards the winding position, and the gas has a certain temperature. This is used to melt the surface plastic of the copper wire winding the coil to a certain extent, so that the copper wire has a certain degree of stickiness, thereby enabling the contacting copper wires to stick together and preventing the coil from unraveling on its own. At the same time, the coil also has a certain degree of stickiness with the second push rod 3067 located therein. It should be noted that the melting is only a certain degree of melting, not complete melting, and the contacting copper wires are still insulated from each other.

[0087] The third mounting bracket 3062 can move back and forth along a direction parallel to the first line of symmetry, thereby moving the second rotating component directly above the first rotating component and the placement block 203.

[0088] Two clamping plates 205 are provided on the fixed plate 202 at positions corresponding to each winding station. Each clamping plate 205 corresponds to a placement block 203 and is located directly above the placement block 203. The clamping plates 205 can move back and forth along their corresponding first symmetry lines. A slot 206 is provided on the clamping plate 205 facing the placement block 203 for placing the coil 100. The diameter of the slot 206 is equal to or slightly larger than the outer diameter of the coil 100. When the coil 100 is in place, the clamping plate 205 can move towards the coil 100 to hold it in place. The clamping plates 205 are driven by a cylinder.

[0089] After the winding is complete and the clamp 301 cuts the copper wire, the fourth mounting bracket 3063 moves upward a certain distance. The third mounting bracket 3062 drives the second rotating assembly to move directly above the placement block 203 where the coil is placed. The fourth mounting bracket 3063 descends a certain height, bringing the coil 100 into contact with the placement block 203, and the clamping plate 205 moves towards the coil 100, securing it. Then, the second push rod 3067 moves upward while the second sleeve 3065 remains stationary, allowing the coil to disengage from the second push rod 3067. Finally, the fourth mounting bracket 3063 moves upward, completely detaching the coil 100 from the second rotating assembly and placing it on the placement block 203. The clamping plate 205 retracts.

[0090] Specifically, as the second push rod 3067 moves downward directly above the placement block 203, it first contacts the upper end of the first guide rod 208 and presses it downward. When the second push rod 3067 moves upward, the first guide rod 208 moves upward; that is, when the second push rod 3067 is pulled out of the coil, the first guide rod 208 enters the coil 100. The first guide rod 208 can position the coil, preventing the coil 100 from moving within the placement block 203 during subsequent operations.

[0091] The integrated machine also includes a laser module 4 installed at the peeling station on the frame 1. The laser module 4 is used to irradiate the wire end from directly above or below the wire end of the coil to completely melt the surface plastic of a portion of the wire end. The wire end with the melted surface plastic is used for wiring.

[0092] The laser module 4 has two sets. One set shines downwards from directly above the wire end to melt the plastic on the upper half of the wire end surface. The other set shines upwards from directly below the wire end to melt the plastic on the lower half of the wire end surface. For ease of description, the two sets of laser modules 4 are referred to as the first laser module and the second laser module, respectively. The two laser modules each correspond to a peeling station, which are referred to as the first peeling station and the second peeling station, respectively.

[0093] The first laser module includes a laser mounting frame 401 mounted on the frame 1 at a first peeling station and a laser source 402 mounted on the laser mounting frame 401. The laser source 402 is movable up and down relative to the laser mounting frame 401, and shines downwards, positioned directly above the coil 100 at the first peeling station. The first laser module also includes a first pressing assembly mounted on a fixed plate 202 to prevent the coil 100 from shaking during laser peeling. The first pressing assembly includes two pressing rods 404 and two positioning blocks 403. The two pressing rods 404 correspond to the two coils 100 at the first peeling station and are used to press down the protruding wire ends of the coils 100. The two positioning blocks 403 correspond to the two coils 100 at the first peeling station and are used to press down the main body of the coils 100. When viewed from above, the clamping rod 404 and the corresponding positioning block 403 have a gap in a direction parallel to the corresponding first line of symmetry. The laser beam passes through the gap to peel the coil at a designated position. The two clamping rods 404 and the two positioning blocks 403 can move up and down synchronously. When the coil 100 moves to the first peeling station, the two clamping rods 404 and the two positioning blocks 403 move downward to press down the coil 100. After the upper peeling is completed, the two clamping rods 404 and the two positioning blocks 403 move upward to release the coil 100. The coil 100 then moves to the second peeling station under the drive of the turntable 201.

[0094] The second laser module, not shown in the figure, is housed within the frame 1, while the laser source of the first laser module faces upwards. At the second peeling station, the coil also needs to be pressed during laser irradiation. This can be achieved using either the same first pressing assembly as the first laser module or a second pressing assembly. The second pressing assembly includes two positioning posts 405 and two pressing plates 406 on the fixed plate 202 corresponding to the second peeling station. The two positioning posts 405 correspond to the body of the coil 100 at the second peeling station, and the two pressing plates 406 correspond to the wire ends of the coil 100 at the second peeling station. A perforated structure is provided at one end of the coil 100 placed on the placement block 203, allowing the laser from below to pass through and irradiate the wire end, thus peeling the lower half of the wire end.

[0095] Smoke extraction pipes 408 are respectively installed on the frame 1 of the first peeling station and the second peeling station to extract the smoke generated during the peeling process.

[0096] The integrated machine also includes a welding assembly 6 set at the welding station on the frame 1. The welding assembly 6 is used to weld the coil 100 onto the strip 200. The welding assembly 6 includes a welding frame 606 set at the welding station on the frame 1, two sets of upper welding heads 604 and two sets of lower welding heads 605 set on the welding frame 606. When viewed from above, the two sets of upper welding heads 604, the two sets of lower welding heads 605 and the two coils located at the welding station are respectively located on two straight lines and the two straight lines are respectively parallel to the first symmetry line located at the welding station. Two sets of upper welding heads 604 are arranged horizontally along the corresponding first line of symmetry, and two sets of lower welding heads 605 are also arranged horizontally along the corresponding first line of symmetry. The distance between the two sets of upper welding heads 604 and the distance between the two sets of lower welding heads 605 are equal to the distance between the two coils 100 located at the welding station. One set of upper welding heads 604 corresponds to one set of lower welding heads 605. There are two sets of upper welding heads 604. The two upper welding heads 604 in the same set are used to weld the two ends of one coil 100 respectively. The lower welding head 605 is plate-shaped and there is only one piece. It contacts the two ends of the coil 100 simultaneously from below. When welding, the upper welding head 604 moves downward and presses the ends of the coil 100 and the corresponding solder joints on the material strip 200 onto the lower welding head 605. Then the circuit is turned on, and the upper welding head 604 and the lower welding head 605 generate heat to melt the solder at the solder joints on the material strip 200, thereby realizing the welding of the coil 100 and the material strip 200. The two upper welding heads 604 in the same group are independently controlled, each driven up and down by a cylinder.

[0097] The welding assembly 6 also includes a strip guide rail 609 mounted on the frame 1. The strip guide rail 609 is provided with two strip grooves 6091. The strip 200 is placed in the strip grooves 6091 and moves along the strip grooves 6091. The two strip grooves 6091 are arranged in parallel along the extension direction of the first symmetrical line parallel to the welding station. The two strip grooves 6091 correspond to the two coils 100 located at the welding station. The strip guide rail 609 is located between the upper welding head 604 and the lower welding head 605. The placement block 203, driven by the turntable 201, can move the wire ends of the two coils 100 located on it to directly below the two sets of upper welding heads 604. The feed strip guide rail 609 can move up and down. When the coil 100 is in position, the feed strip guide rail 609 moves the feed strip 200 downward, so that the position to be soldered on the wire end of the coil 100 is close to or in contact with the solder joint on the feed strip 200. When the feed strip guide rail 609 moves downward, the upper soldering head 604 moves downward and comes into contact with the solder joint on the feed strip 200, the wire end of the coil 100, and the lower soldering head 605, generating a certain force. The upper soldering head 604 and the lower soldering head 605 generate high temperature after being energized, melting the solder at the solder joint, thus achieving the soldering of the wire end to the feed strip 200. After the soldering is completed, the feed strip guide rail 609 moves upward, driving the feed strip 200 and the coil 100 soldered on the feed strip 200 upward, so that the coil 100 is detached from the first guide rod 208. When the feed strip guide rail 609 moves upward, the feed strip 200 moves forward a certain distance to prepare for the next soldering.

[0098] Two strip reels 601 are mounted on the frame 1, with strip 200 to be welded wound on them. The two reels 601 correspond to two strip grooves 6091 on the strip guide rail 609. Multiple first guide rollers 603 are mounted on the fixed plate 202 to guide the strip 200 to be welded. The strip 200 enters the strip groove 6091 from the side closest to the axis of the turntable 201. Two pressure rollers 614 are mounted on the strip guide rail 609 at one end near the axis of the turntable 201. The two pressure rollers 614 correspond to the two strip grooves 6091 and are rotatable with their rotation axes perpendicular to the direction of movement of the strip 200 in the strip grooves 6091. The strip 200 passes under the pressure rollers 614, which confine the strip 200 within the strip grooves 6091.

[0099] The lower welding head 605 can move back and forth along the direction of approaching or moving away from the turntable 201. When the coil 100 moves to the welding position, the lower welding head 605 moves along the direction of approaching the turntable 201, so that the lower welding head 605 is directly below the upper welding head 604. When the turntable 201 drives the coil 100 to rotate, the lower welding head 605 moves to a position away from the turntable 201 to avoid collision between the lower welding head 605 and the structure on the turntable 201 during the rotation of the turntable 201.

[0100] The welding assembly also includes a welding head cleaning assembly 607 mounted on the frame 1. The welding head cleaning assembly 607 is used to clean the upper welding head 604 and the lower welding head 605. The welding frame 606 can move back and forth along the direction in which the two sets of upper welding heads 604 are arranged. The welding head cleaning assembly 607 includes a cleaning frame 6075 mounted on the frame 1 and located on one side of the welding frame 606 along its moving direction, a cleaning reel 6072 rotatably mounted on the cleaning frame 6075, a cleaning belt 6071, two second guide rollers 6074 rotatably mounted on the cleaning frame 6075, and a drive roller 6073. The cleaning belt 6071 to be used is wound around the cleaning reel 6072. The two second guide rollers 6074 are arranged along the moving direction of the welding frame 606 and their rotation axes are perpendicular to the moving direction. A portion of the cleaning belt 6071 is wound around the two second guide rollers 6074. The cleaning belt 6071 can move under the drive of the drive roller 6073. When viewed from above, the two sets of upper welding heads 604 and the two second guide rollers 6074 are on the same straight line. When cleaning is required, the welding frame 606 moves the upper welding head 604 and the lower welding head 605 to the position corresponding to the two second guide rollers 6074. The two second guide rollers 6074 can move up and down. After the upper welding head 604 and the lower welding head 605 are in place, the two second guide rollers 6074 drive the cleaning belt 6071 to move downward, so that the cleaning belt 6071 located on the lower side contacts the lower welding head 605. The upper welding head 604 moves downward and contacts the cleaning belt 6071 located on the upper side. The transmission roller 6073 rotates in a predetermined direction, driving the cleaning belt 6071 to move a predetermined distance to clean the upper welding head 604 and the lower welding head 605. Then the welding frame 606 returns to the work position with the upper welding head 604 and the lower welding head 605.

[0101] Along the movement direction of the strip 200 on the strip guide rail 609, a coil detection component 610, a wire end cutting component 611, a laser welding component 612, and a first strip drive component 613 are sequentially arranged on the frame and downstream of the upper welding head 604. The coil detection component 610 is used to detect whether there is a coil 100 on the strip 200. The wire end cutting component 611 is used to cut off the excess wire end of the coil 100 welded to the strip 200. There are two sets of wire end cutting components 611, and the two sets of wire end cutting components 611 are independently controlled. When the coil detection component 610 detects that there is no corresponding coil on one of the strips 200, the corresponding wire end cutting component 611 does not work. The laser welding component 612 is used to laser heat the solder joint, so that the solder remelts. It adopts a non-contact method to avoid squeezing the solder, which can make the solder more rounded and the welding effect better. The laser welding assembly 612 has a laser head that can move back and forth in a vertical plane perpendicular to the movement of the strip 200 to laser heat the weld point that has been moved into place. Similarly, if the coil detection assembly 610 detects that there is no coil 100 at the corresponding position on the strip 200, the laser head will not perform the corresponding operation.

[0102] The first material strip driving assembly 613 includes a driving arm 6131 extending along the arrangement direction of the two material strip grooves 6091 and two driving rods 6132. The two driving rods 6132 extend downward and correspond to the two material strip grooves 6091 respectively. The driving arm 6131 can move up and down and can move in a direction parallel to the material strip grooves 6091. When it is necessary to move the material strip 200, the driving arm 6131 drives the two driving rods 6132 to move downward and insert them into the hollow of the material strip 200. Then, the driving arm 6131 moves away from the turntable 201. The driving arm 6131 is driven by a motor and a lead screw. The distance that the driving arm 6131 moves each time is the distance between two adjacent coils 100 on the material strip 200.

[0103] The integrated machine also includes a feeding assembly 7 mounted on the frame 1. The feeding assembly 7 includes a feeding guide rail 701 mounted on the frame 1. The feeding guide rail 701 is located on the side of the material belt guide rail 609 away from the turntable 201. The feeding guide rail 701 is also provided with two material belt grooves. The material belt grooves 6091 on the material belt guide rail 609 are aligned with the material belt grooves on the feeding guide rail 701. The material belt 200 coming out of the material belt grooves 6091 on the material belt guide rail 609 enters the material belt grooves on the feeding guide rail 701 and continues to move away from the material belt guide rail 609. Along the movement direction of the material strip 200 on the feeding guide rail 701, a straightening component 702, a weld point detection component 703, a marking component 704, a second material strip drive component 705, a cutting component 708, a pouring component 706, and a receiving box 707 are sequentially arranged. The material strip 200 passes through the straightening component 702, which is used to straighten the material strip. The straightening component 702 adopts existing technology. The weld point detection component 703 is used to detect weld points to determine whether the welding meets the requirements. The weld point detection component 703 uses an industrial camera to capture images of the weld points. The quality of the weld points is determined by image analysis. The image analysis adopts existing technology. The marking component 704 is used to mark weld points that do not meet the quality requirements. The marking is specifically an indentation on the material strip 200 at the location of the non-compliant weld point. The marking component 704 can be driven by a cylinder to move the pressure block, creating an indentation on the material strip 200. In practice, the weld point detection component 703 and the marking component 704 can be omitted. The second strip drive component 705 has the same structure as the first strip drive component 613, both used to drive the strip 200 forward. The cutting component 708 includes two cutters 7081, with the blades of the two cutters 7081 facing downwards. Each cutter 7081 corresponds to one of the two strips 200. Each cutter 7081 is driven up and down by a cylinder, and the two cutters 7081 are independently controlled. A cutout is provided on the feeding guide 701 at the position corresponding to each cutter 7081, allowing the cutter 7081 to be inserted into the cutout during cutting to ensure that the strip 200 is completely cut. The length of the strip 200 to be cut can be determined according to the actual situation. The material pouring assembly 706 includes two material pouring plates 7061, which correspond to the two material strip grooves of the feeding guide rail 701 respectively. The two cut material strips 200 sent out from the feeding guide rail 701 enter the material pouring plates 7061.The pouring plate 7061 can rotate at a certain angle to move the pouring plate 7062 between a first position and a second position. Its rotation axis is parallel to the movement direction of the material strip 200 on the feeding guide rail 701. When the pouring plate 7061 is in the first position, the pouring plate 7061 is horizontally arranged, and the cut material strip 200 can move to the surface of the pouring plate 7061. When the pouring plate 7061 is in the second position, the side of the two pouring plates 7061 that is close to each other is higher, and the side that is far away from each other is lower. When the pouring plate 7061 rotates from the first position to the second position, the material strip 200 slides off the pouring plate 7061 into the receiving box 707, which can ensure that the material strip 200 is neatly arranged in the receiving box 707.
