[0082] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.
[0083] like Figure 1-31 As shown, a winding and welding integrated machine includes a frame 1, a turntable module 2 arranged on the frame 1, and a winding module 3.
[0084] The turntable module 2 includes a turntable 201 rotatably mounted on the frame 1 and a fixed plate 202 fixed to the frame 1 and located directly above the turntable 201. The axis of the turntable 201 is vertically arranged, and the axis of the fixed plate 202 is coaxially arranged with the axis of the turntable 201. The turntable module 2 also includes multiple groups of placement blocks 203 disposed on the edge of the turntable 201. The multiple groups of placement blocks 203 are evenly arranged on the edge of the turntable 201, and each group of placement blocks 203 has two placement 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 is provided with an end plate 204 at one end facing away from the axis of the turntable 201. The plane on which the end plate 204 lies is perpendicular to its corresponding first line of symmetry, and 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, close to the end plate 204. Two first wire grooves 2041 are provided on the end plate 204. The two first wire grooves 2041 are open upward and 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 wire ends pass through the first wire grooves 2041.
[0085] A first guide rod 208 is provided at the location on each placement block 203 for placing the coil 100. 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, which can move up and down. Two buffer springs 210 are provided below the buffer block 209, with the upper ends of the buffer springs 210 resting on the lower surface of the buffer block 209. The buffer springs 210 are always compressed, and thus can rest against the placement block 203 when no external force is applied to the buffer block 209. When the coil 100 is placed on the placement block 203, the coil 100 is sheathed on the first guide rod 208 to prevent the coil 100 from moving back and forth.
[0086] The winding modules 3 are arranged in three groups, each with identical structures. The three groups are capable of operating simultaneously and are arranged in sequence along the direction of rotation of the turntable 201, i.e., they comprise three winding stations, allowing for simultaneous winding. Furthermore, the angle between adjacent winding modules 3 relative to the rotation axis of the turntable 201 is equal to the angle between two adjacent groups of placement blocks 203 relative to the selected welding axis of the turntable 201. Each group of winding modules 3 comprises a first mounting plate 302 and two fixtures 301 disposed on the first mounting plate 302. The arrangement direction of the two fixtures 301 is parallel to the arrangement direction of the two placement blocks 203 located at the corresponding winding station, and the distance between the jaws of the two fixtures 301 is equal to the distance between the two placement blocks 203 located in the same group. The first mounting plate 302 is disposed on the frame 1 and is capable of moving back and forth within a certain range within a horizontal plane relative to the frame 1.
[0087] Each clamp 301 includes a fixed arm 3012 fixed to the 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 fixed arm 3012 and the end of the movable arm 3011 near the turntable 201 can move closer to or farther from each other to close or open the clamping mouth, thereby clamping or releasing the copper wire. Preferably, the two movable arms 3011 on the same winding module 3 are driven by the same driving cylinder 303. A blade 3013 is provided on the end face of the fixed arm 3012 near the turntable 201, which simultaneously cuts the copper wire while clamping it.
[0088] A wire tube 304 is provided on the side opposite the rotating disk 201 and extending along its corresponding first line of symmetry. Its height matches the height of the clamping opening. The copper wire passes through the wire tube 304 and the clamping opening in sequence. The wire tube 304 is immovable relative to its corresponding fixed arm 3012.
[0089] 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 frame 3051 disposed on the frame 1, a second mounting frame 3052 movably disposed on the first mounting frame 3051, and two sets of first rotating assemblies 3053 rotatably disposed on the second mounting frame 3052. The two sets of first rotating assemblies 3053 are arranged along the arrangement direction of the two clamping openings, and the distance between the axes of the two sets of first rotating assemblies 3053 is equal to the distance between the two clamping openings.
[0090] Each first rotating assembly 3053 includes a first sleeve 30531 rotatably mounted on the second mounting frame 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. The first rotating head 30532 is provided with a mounting slot 30534, within which is disposed an L-shaped top arm 30535. A through hole is provided in the portion of the first rotating head 30532 located in the mounting slot 30534, connecting the mounting slot 30534 with the hollow portion of the first sleeve 30531. The through hole is coaxial with the first sleeve 30531. The first rotating assembly 3053 also includes a first push rod 30536, which is located in the first sleeve 30531 and is coaxially arranged with the first sleeve 30531. The lower end of the first push rod 30536 extends 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, and the higher end of the top arm 30535 is provided with a pressing block 305310. The placement platform 30539 is located directly above the lower portion of the top arm 30535 and on one side of the higher portion of the top arm 30535. The pressing block 305310 is closer to the placement platform 30539 than the top arm 30535. A stopper 305311 is provided on one side of the placement platform 30539. The pressing block 305310 can be selectively pressed on the stopper 305311. The top arm 30535 is rotatably mounted on the first rotating head 30532 via a connecting rod 305313. The first top rod 30536 is movable 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 allows the upper end of the top arm 30535 to drive the pressing block 305310 to move back and forth, thereby enabling the pressing block 305310 to press or release from the stop block 305311. When the pressing block 305310 is pressed against the stop block 305311, the copper wire can be clamped. Preferably, a wire clamping groove is provided on the side of the pressing block 305310 facing the stop block 305311 to better clamp the copper wire. When winding, the clamp 301 clamps the end of the copper wire and moves toward the corresponding first rotating head 30532 and crosses 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 winding.
[0091] 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 slot 305314 is provided on the first rotating head 30532 at a position corresponding to the limiting rod 30537. The limiting slot 305314 is connected to the mounting slot 30534 and extends in the vertical direction. The two ends of the limiting rod 30537 are inserted into the corresponding limiting slots 305314 and can slide vertically within the dimensional range of the limiting slots 305314. The cooperation between the limiting rod 30537 and the limiting slot 305314 can limit the vertical movement range of the first push rod 30536.
[0092] 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 and on the side away from the first pull rod 305315. The first pull rod 305315 and the second pull rod 305316 are parallel and both 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.
[0093] A pulley 30533 is provided on the first sleeve 30531, and a motor is provided on the second mounting frame 3052. The motor is connected to the pulley 30533 through a belt, and the motor can drive the first sleeve 30531 and other structures on the first sleeve 30531 to rotate together.
[0094] Furthermore, a first push block 305317 is provided on the second mounting frame 3052, directly below each first push rod 30536. Under the action of a tension spring 305312, the lower end of the first push rod 30536 always abuts against the first push block 305317, allowing the first push block 305317 to move up and down. When the copper wire needs to be loosened, the first push block 305317 pushes the first push rod 30536 upward, which in turn drives the push arm 30535 to rotate, thereby disengaging the pressing block 305310 from the stop block 305311. The first push block 305317 is driven by a pneumatic cylinder.
[0095] The guide assembly 306 includes a support rod 3061 arranged on the frame 1, a third mounting frame 3062 supported on the support rod 3061, a fourth mounting frame 3063 supported below the third mounting frame 3062 for vertical movement, and two second rotating assemblies arranged on the fourth mounting frame 3063, each second rotating assembly includes a second sleeve 3065 rotatably arranged on the fourth mounting frame 3063, a second rotating head 3066 arranged at the lower end of the second sleeve 3065, and a second push rod 3067 arranged in the second sleeve 3065, the second rotating head 3066 is coaxially arranged with the second sleeve 3065, the second push rod 3067 is coaxially arranged with the second sleeve 3065, the upper end of the second push rod 3067 passes through the upper end of the second sleeve 3065, and the lower end passes through the second rotating head 3066, and the second push rod 3067 can move 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.
[0096] 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, and the second mounting bracket 3052 moves upward, so that the upper end of the first push rod 30536 contacts the lower end of the corresponding second push rod 3067. When winding begins, 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 rotates along with the first rotating assembly, allowing the copper wire to be wound around the portion of the second push rod 3067 that extends from the second rotating head 3066. Furthermore, during the winding process, the coil has a certain height in the vertical direction, so the second mounting bracket 3052 and the fourth mounting bracket 3063 need to move up and down synchronously. In practice, the coil 100 has two layers, inside and outside, with the outer layer wound after the inner layer is wound. After winding of one coil 100 is completed, the clamp 301 is moved to clamp the copper wire between the coil 100 and the bobbin 304 and cut the copper wire at the same time.
[0097] A second push block 3068 is provided on the fourth mounting frame 3063 at a position corresponding to each second push rod 3067. The second push block 3068 is movable up and down. The upper end of the second push rod 3067 abuts against the second push block 3068, and the second push rod 3067 is driven up and down by the second push block 3068. Preferably, a bearing can be provided at the upper end of the second push rod 3067, fixed to the second push block 3068, to reduce friction between the second push rod 3067 and the second push block 3068. The second push rod 3067 is driven by a pneumatic cylinder.
[0098] Furthermore, an air blow pipe 3064 is provided on the fourth mounting bracket 3063, corresponding to each second rotating assembly. This blow pipe 3064 blows air at a certain temperature toward the winding location, causing the plastic surface of the copper wires used to form the coils to melt to a certain extent. This imparts a certain degree of stickiness to the copper wires, thereby allowing them to adhere to each other and prevent the coils from unraveling. Furthermore, the coils also exhibit a certain degree of stickiness to the second ejector pin 3067 located therein. It should be noted that this melting is only partial, not complete, and the contacting copper wires remain insulated.
[0099] The third mounting bracket 3062 can move back and forth along a direction parallel to the first symmetry line, thereby moving the second rotating assembly to directly above the first rotating assembly and the placement block 203 .
[0100] Two clamping plates 205 are installed on the fixed disk 202 at positions corresponding to each winding station. These clamping plates 205 correspond one-to-one with the placement blocks 203 and are located directly above them. These clamping plates 205 are movable back and forth along their corresponding first lines of symmetry. A clamping slot 206 is provided on the clamping plates 205, facing the placement blocks 203, where the coil 100 is placed. The diameter of these clamping slots 206 is equal to or slightly larger than the outer diameter of the coil 100. Once the coil 100 is in place, the clamping plates 205 can move toward the coil 100 to secure it. The clamping plates 205 are driven by a pneumatic cylinder.
[0101] When the winding is completed and the clamp 301 cuts the copper wire, the fourth mounting bracket 3063 moves upward for a distance. The third mounting bracket 3062 drives the second rotating assembly to move to the position directly above the placement block 203 for placing the coil. The fourth mounting bracket 3063 descends to a certain height so that the coil 100 contacts the placement block 203, and the clamping plate 205 moves toward the coil 100 to clamp the coil 100. Then, the second push rod 3067 moves upward, and the second sleeve 3065 does not move, so that the coil is separated from the second push rod 3067. Finally, the fourth mounting bracket 3063 moves upward, and the coil 100 is completely separated from the second rotating assembly and placed on the placement block 203. The clamping plate 205 retracts.
[0102] 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 the first guide rod 208 downward. As the second push rod 3067 moves upward, the first guide rod 208 also moves upward. That is, as the second push rod 3067 is withdrawn from the coil, the first guide rod 208 enters the coil 100. The first guide rod 208 positions the coil, preventing it from moving on the placement block 203 during subsequent operations.
[0103] The all-in-one machine also includes a laser module 4 arranged at the peeling station on the frame 1, and the laser module 4 is used to irradiate the laser toward the wire end from directly above or directly below the wire end of the coil to completely melt the surface plastic on a part of the wire end. The wire end with melted surface plastic is used for wiring.
[0104] There are two groups of laser modules 4, one group irradiates downward from directly above the thread head to melt the plastic on the upper half of the surface of the thread head, and the other group irradiates upward from directly below the thread head to melt the plastic on the lower half of the surface of the thread head. For the convenience of description, the two groups of laser modules 4 are respectively referred to as the first laser module and the second laser module. The two laser modules correspond to one peeling station respectively. For the convenience of description, they are respectively referred to as the first peeling station and the second peeling station.
[0105] The first laser module includes a laser mounting frame 401 arranged at the first peeling station on the frame 1 and a laser light source 402 arranged on the laser mounting frame 401. The laser light source 402 can move up and down relative to the laser mounting frame 401, and the laser light source 402 irradiates downward. The laser light source 402 is located directly above the coil 100 at the first peeling station. The first laser module also includes a first pressing assembly arranged on the fixed disk 202, which is used to prevent the coil 100 from shaking during laser peeling. The first pressing assembly includes two clamping rods 404 and two positioning blocks 403. The two clamping rods 404 correspond to the two coils 100 at the first peeling station respectively, and the clamping rods 404 are used to press the thread ends protruding from the coils 100. The two positioning blocks 403 correspond to the two coils 100 at the first peeling station respectively, and the positioning blocks 403 are used to press the main body of the coil 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 symmetry line. The laser light passes through the gap to peel the designated position on the thread head. 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 the coil 100. When the peeling of the upper part is completed, the two clamping rods 404 and the two positioning blocks 403 move upward to release the coil 100. The coil 100 is then driven by the turntable 201 to move to the second peeling station.
[0106] The second laser module is not shown in the figure. It is arranged in the frame 1, and the laser light source of the first laser module irradiates upward. At the second peeling station, when the laser is irradiated, the coil also needs to be pressed. The same first pressing assembly as in the first laser module can be used, or a second pressing assembly can be used. The second pressing assembly includes two positioning posts 405 and two pressing plates 406 corresponding to the second peeling station arranged on the fixed disk 202. 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 thread ends of the coil 100 at the second peeling station. A hollow structure is provided at one end of the placement block 203 where the coil 100 is placed. The laser below can pass through the hollow structure and irradiate the thread end, thereby peeling the lower half of the thread end.
[0107] Smoke extraction pipes 408 are respectively provided on the frames 1 of the first peeling station and the second peeling station for extracting smoke generated during the peeling process.
[0108] The all-in-one machine also includes a welding assembly 6 arranged at a welding station on the frame 1, and the welding assembly 6 is used to weld the coil 100 to the material strip 200. The welding assembly 6 includes a welding frame 606 arranged at the welding station on the frame 1, two groups of upper welding heads 604 and two groups of lower welding heads 605 arranged on the welding frame 606. When viewed from above, the two groups of upper welding heads 604, the two groups 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. The two groups of upper welding heads 604 are arranged along a horizontal direction perpendicular to the corresponding first symmetry line, and the two groups of lower welding heads 605 are also arranged along a horizontal direction perpendicular to the corresponding first symmetry line. The distance between the two groups of upper welding heads 604 and the distance between the two groups of lower welding heads 605 are equal to the distance between the two coils 100 located at the welding station. One group of upper welding heads 604 corresponds to one group of lower welding heads 605. A group of upper welding heads 604 has two. The two upper welding heads 604 in the same group are respectively used for the two wire ends of a coil 100. The lower welding head 605 is plate-shaped and has only one piece. It contacts the two wire ends of the coil 100 at the same time from the bottom. When welding, the upper welding head 604 moves downward and presses the wire ends of the coil 100 and the corresponding solder points 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 points on the material strip 200, thereby realizing the welding of the coil 100 and the material strip 200. The two upper welding heads 604 of the same group are independently controlled and are each driven up and down by a cylinder.
[0109] The welding assembly 6 also includes a material strip guide rail 609 arranged on the frame 1, and two material strip grooves 6091 are provided on the material guide rail 609. The material strip 200 is placed in the material strip groove 6091 and moves along the material strip groove 6091. The two material strip grooves 6091 are arranged in parallel along the extension direction of the first symmetry line located parallel to the welding station. The two material strip grooves 6091 correspond to the two coils 100 located at the welding station. The material 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 thereon to directly below the two groups of upper welding heads 604 respectively. The material strip guide 609 can move up and down. When the coil 100 is moved into position, the material strip guide 609 moves the material strip 200 downward, so that the position on the wire end of the coil 100 that needs to be welded is close to or in contact with the welding point on the material strip 200. When the material strip guide 609 moves downward into position, the upper welding head 604 moves downward and contacts the welding point on the material strip 200, the wire end of the coil 100, and the lower welding head 605, generating a certain force. When the upper welding head 604 and the lower welding head 605 are energized, they generate high temperatures, melting the solder at the welding point, and achieving welding of the wire end to the material strip 200. When welding is completed, the material strip guide 609 moves upward, driving the material strip 200 and the coil 100 welded on the material strip 200 upward, so that the coil 100 is separated from the first guide rod 208. When the material strip guide 609 moves upward into position, the material strip 200 moves forward a distance to prepare for the next welding.
[0110] Two tape reels 601 are mounted on the frame 1, with the tape 200 to be welded wound around them. The two reels 601 correspond to two tape slots 6091 on the tape guide rail 609. Multiple first guide rollers 603 are mounted on the fixed disk 202 to guide the tape 200 to be welded. The tape 200 enters the tape slots 6091 from the side near the axis of the turntable 201. Two pinch rollers 614 are mounted on the tape guide rail 609, near one end of the turntable 201. The pinch rollers 614 correspond to the two tape slots 6091, respectively. The pinch rollers 614 are rotatable, with their axes of rotation perpendicular to the direction of movement of the tape 200 within the tape slots 6091. The tape 200 passes beneath the pinch rollers 614, which can hold the tape 200 within the tape slots 6091.
[0111] The lower welding head 605 can move back and forth in a direction toward or away from the turntable 201. When the coil 100 moves to the welding position, the lower welding head 605 moves toward the turntable 201, so that the lower welding head 605 moves 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 prevent the lower welding head 605 from colliding with the structure on the turntable 201 during the rotation of the turntable 201.
[0112] The welding assembly also includes a welding head cleaning assembly 607 disposed on the frame 1, and 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 is capable of moving back and forth along the direction in which the two groups of upper welding heads 604 are arranged. The welding head cleaning assembly 607 includes a cleaning frame 6075 disposed on the frame 1 and located on one side of the welding frame 606 along its movement direction, a cleaning belt reel 6072 rotatably disposed on the cleaning frame 6075, a cleaning belt 6071, two second guide rollers 6074 rotatably disposed on the cleaning frame 6075, and a transmission roller 6073. The cleaning belt 6071 to be used is wound around the cleaning belt reel 6072. The two second guide rollers 6074 are arranged along the movement direction of the welding frame 606 with their rotation axes perpendicular to the movement direction. A portion of the cleaning belt 6071 is wound around the two second guide rollers 6074, and the cleaning belt 6071 is capable of moving under the drive of the transmission roller 6073. When viewed from above, the two groups of upper welding heads 604 and the two second guide rollers 6074 are in 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 position between the two second guide rollers 6074. The two second guide rollers 6074 can move up and down. When the upper welding head 604 and the lower welding head 605 are moved into place, the two second guide rollers 6074 drive the cleaning belt 6071 to move downward, so that the cleaning belt 6071 on the lower side contacts the lower welding head 605, and the upper welding head 604 moves downward and contacts the cleaning belt 6071 on the upper side. The transmission roller 6073 rotates in a predetermined direction, driving the cleaning belt 6071 to move a predetermined distance, thereby cleaning the upper welding head 604 and the lower welding head 605. Then the welding frame 606 returns the upper welding head 604 and the lower welding head 605 to the work position.
[0113] Along the direction of movement of the material strip 200 on the material strip guide rail 609, a coil detection assembly 610, a wire end cutting assembly 611, a laser welding assembly 612, and a first material strip drive assembly 613 are sequentially arranged on the frame and downstream of the upper welding head 604. The coil detection assembly 610 is used to detect whether there are coils 100 on the material strip 200. The wire end cutting assembly 611 is used to cut off excess wire ends from the coils 100 welded to the material strip 200. There are two sets of wire end cutting assemblies 611, and the two sets of wire end cutting assemblies 611 are independently controlled. When the coil detection assembly 610 detects that there are no coils on one of the material strips 200, the corresponding wire end cutting assembly 611 does not operate. The laser welding assembly 612 is used to laser heat the solder joints to remelt the solder. Using a non-contact method, it avoids squeezing the solder, making the solder more rounded and achieving better welding results. The laser welding assembly 612 includes a laser head that can move back and forth in a vertical plane perpendicular to the movement of the material strip 200 to laser heat the weld points that have been moved into position. Similarly, if the coil detection assembly 610 detects that there is no coil 100 at the corresponding position on the material strip 200, the laser head will not perform the corresponding operation.
[0114] The first strip drive assembly 613 includes a drive arm 6131 and two drive rods 6132 extending along the alignment of the two strip slots 6091. The two drive rods 6132 extend downward and correspond to the two strip slots 6091, respectively. The drive arm 6131 is capable of moving up and down and in a direction parallel to the strip slots 6091. When the strip 200 needs to be moved, the drive arm 6131 drives the two drive rods 6132 downward and inserts them into the hollow space of the strip 200. The drive arm 6131 then moves away from the turntable 201. The drive arm 6131 is driven by a motor and a screw. Each movement of the drive arm 6131 is the distance between two adjacent coils 100 on the strip 200.
[0115] The all-in-one machine also includes a blanking component 7 arranged on the frame 1, and the blanking component 7 includes a blanking guide rail 701 arranged on the frame 1, and the blanking guide rail 701 is arranged on the side of the material belt guide rail 609 away from the turntable 201, and two material belt grooves are also provided on the blanking guide rail 701. The material belt groove 6091 on the material belt guide rail 609 is aligned one by one with the material belt groove on the blanking guide rail 701, and the material belt 200 coming out of the material belt groove 6091 on the material belt guide rail 609 enters the material belt groove of the blanking guide rail 701 and continues to move in the direction away from the material belt guide rail 609. Along the direction of movement of the material strip 200 on the unloading guide rail 701, a straightening assembly 702, a solder joint inspection assembly 703, a marking assembly 704, a second material strip drive assembly 705, a cutting assembly 708, a material unloading assembly 706, and a material receiving box 707 are sequentially arranged. The material strip 200 passes through the straightening assembly 702, which is used to straighten the material strip and uses existing technology. The solder joint inspection assembly 703 is used to inspect solder joints to determine whether the welds meet the requirements. The solder joint inspection assembly 703 uses an industrial camera to capture images of the solder joints and analyze the images to determine the quality of the solder joints. The image analysis uses existing technology. The marking assembly 704 is used to mark solder joints that do not meet the quality requirements. Specifically, the mark is an indentation on the material strip 200 at the location of the non-compliant solder joint. The marking assembly 704 can use a cylinder to drive a pressure block to move, creating an indentation on the material strip 200. In practice, the solder joint detection component 703 and the marking component 704 can be eliminated. The second material strip drive component 705 has the same structure as the first material strip drive component 613, and is used to drive the material strip 200 to move forward. The cutting component 708 includes two cutters 7081, the blades of the two cutters 7081 are facing downward, and the two cutters 7081 correspond to two material strips 200 respectively. Each cutter 7081 is driven up and down by a cylinder, and the two cutters 7081 are independently controlled. Hollows are provided at the position corresponding to each cutter 7081 of the unloading guide rail 701, and the cutter 7081 can be inserted into the hollows during cutting to ensure that the material strip 200 can be completely cut. The length of the material strip 200 that needs to be cut can be determined according to actual conditions. The unloading assembly 706 includes two unloading plates 7061 , which respectively correspond to the two material strip grooves of the unloading guide rail 701 . The two cut material strips 200 sent out from the unloading guide rail 701 enter the unloading plates 7061 .The pouring plate 7061 can be rotated by a certain angle to enable the pouring plate 7062 to move between the first position and the second position, and its rotation axis is parallel to the moving direction of the material strip 200 on the unloading guide rail 701. When the pouring plate 7061 is in the first position, the pouring plate 7061 is arranged horizontally, and the cut material strip 200 can be moved 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 are close to each other is higher, and the side that is 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 from the pouring plate 7061 into the material receiving box 707, so that the material strip 200 can be arranged neatly in the material receiving box 707.
