Description

Technical Field

[0001] The invention relates to a coating traction structure, in particular to a coating traction device and method for producing electromagnetic wires. Background Art

[0002] Electromagnetic wire, also known as winding wire, is an insulated wire used to manufacture coils or windings in electrical products. During the production process of electromagnetic wire, it is necessary to coat the outer side of the winding with film material for protection. However, the traction device used to pull the electromagnetic wire generally still adopts a set of fixed installation roller structures, such as the traction assembly disclosed in the patent of an electromagnetic wire core coating device (Announcement No. CN220796354U). The traction assembly disclosed in the patent includes a first bracket, and the inner side of the first bracket is rotatably connected to a traction roller that fits the electromagnetic wire. One end of the traction roller is detachably fixed to the output shaft of the servo motor, and a pad fixed to the first bracket is fixed to the outer side of the servo motor. The outer side of the first bracket is fixedly connected to the base. Therefore, the installation and positioning of the first section and the tail end of the electromagnetic wire still requires a lot of manual participation. Therefore, it is time-consuming and labor-intensive, and the degree of automation is also low. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a coating traction device and method for electromagnetic wire production, which can realize automated roll changing operations and can also realize direct stacking and storage unloading after roll changing, with a higher degree of automation and more time-saving and labor-saving.

[0004] The present invention provides the following technical solutions:

[0005] A film-wrapped traction device and method for producing electromagnetic wires, comprising a mounting side frame and four traction assemblies uniformly arranged circumferentially on the mounting side frame. The four traction assemblies are driven to rotate by a transposition motor on the mounting side frame to sequentially transpose to a loading position, a winding position, a stacking position, and an empty position. A loading group is arranged on the side of the loading position away from the mounting side frame. The loading group is used to drive the winding drum to sequentially load the material onto the traction assembly at the loading position, and when the winding drum rotates to the winding position with the traction assembly, the electromagnetic wire is wound. After the winding drum has completed winding, the traction assembly drives the winding drum to rotate to the stacking position. At the stacking position, the traction assembly drives the winding drum to rotate to the stacking position. The assembly is also used to drive the winding drum to approach the rotation center of the installation side frame, and when the rotation center of the installation side frame approaches the three groups of winding drums, the pushing group installed on the installation side frame is started to push the three groups of winding drums away from the traction assembly to unload the materials into the storage group. The storage group includes a receiving groove with openings at both ends, a storage box with openings at both ends, and a conveyor. The conveyor is arranged in the receiving groove, and the feeding end and the unloading end of the conveyor extend to the openings at both ends of the receiving groove respectively. The storage box falls from the through-port opened at the top of the receiving groove to the feeding end of the conveyor, and one end opening of the storage box is aligned with the three groups of winding drums to be separated from the traction assembly;

[0006] The traction assembly then rotates 90° to the stacking position, and the winding drum at the winding position is rotated to the loading position. The third group of winding drums has completed the operation of approaching the center, and the traction assembly in the loading position, the stacking position and the empty position all have a group of winding drums approaching the rotation center, and then the pushing group is started to push the three groups of stacked winding drums together to separate from the traction assembly and unload them into the storage group. The storage box in the storage group is used to receive the three groups of winding drums fed in and is driven by the conveyor belt to transport them away after the receiving is completed, and the traction assembly that has completed the separation of the winding drum returns to its original position away from the center, and the traction assembly in the loading position continues to wait for the loading group to load the material for the next stacking and unloading cycle. In this way, not only the automatic traction and reel changing operation after the electromagnetic wire is coated can be realized, but also the direct stacking and storage unloading operation can be realized after the reel is changed, which has a higher degree of automation and saves time and effort.

[0007] Preferably, a group of cutters are provided between the winding position and the stacking position, and the cutters are driven by a cutting cylinder to perform linear reciprocating motion to cut the electromagnetic wire stretched between the winding position and the stacking position after the winding drum rotates to the stacking position after the winding is completed.

[0008] Preferably, a group of positioning grooves extending axially through are provided on the winding drum, and when the winding drum rotates to the winding position, the positioning grooves rotate to the uppermost position, and a group of pressure rods are further provided above the positioning grooves, and the pressure rods are used to press the electromagnetic wire stretched between the winding position and the stacking position into the positioning grooves, and the cutter is provided above one side of the positioning groove close to the center, and when the pressure rods completely enter the positioning grooves and press the electromagnetic wire to the bottom of the positioning grooves, the cutter descends under the drive of the cutting cylinder to cut the electromagnetic wire. At this time, the surface of the reel can also be used as a cutting support surface when the cutter cuts the electromagnetic wire. The head end of the cut electromagnetic wire is pressed in the positioning groove by the pressure rod, and the tail end can continue to be wound around the reel when the stacking position continues to rotate. At this time, the automatic cutting and reeling operation of the reeling position can be completed, which saves the manual operation of reeling and positioning the electromagnetic wire, saves time and effort, and because the pressure rod is completely inserted into the positioning groove when positioned, after the reeling is completed, the pressure rod can be pulled out from one end of the positioning groove to carry out the next pressing cycle.

[0009] Preferably, one end of the pressure rod is fixed on a group of turntables, and the turntable is connected to a group of positioning side plates and rotates under the drive of the rotary motor. The distance between the pressure rod and the rotation center of the turntable is the same as the distance between the pressure rod and the rotation center of the winding drum when the pressure rod is pressed against the bottom of the positioning groove, and the positioning side plates are installed at a group of Y-axis linear module driving ends, and the Y-axis linear module is installed at a group of X-axis linear module driving ends, and the Y-axis linear module is used to drive the pressure rod to descend and press the electromagnetic wire to the bottom of the positioning groove, and the rotary motor is used to synchronously rotate the pressure rod to rotate with the winding drum when the winding drum is performing the winding operation, and the X-axis linear module is used to drive the pressure rod to axially withdraw from the positioning groove after the head end of the electromagnetic wire on the winding drum completes the winding positioning;

[0010] At this point, the reel changing operation can be completed in a fully automated operation. Specifically, first, the reel drum that has completed reeling at the reeling position is driven by the reeling motor to rotate 90 degrees to the stacking position, and the reel drum to be reeled, which was originally the loading position, is rotated to the reeling position. At this time, there is still uncut electromagnetic wire stretched between the reeling position and the stacking position, and then the Y-axis linear module is started to make the pressure rod descend, and the pressure rod can press the electromagnetic wire until the pressure rod completely enters the positioning groove, and the electromagnetic wire is pressed between the pressure rod and the bottom of the positioning groove, and then the cutter can be started to descend to cut the electromagnetic wire pulled between the reeling position and the stacking position, and the electromagnetic wire pressed and positioned by the pressure rod can be used as the head end of the electromagnetic wire to be reeled, and after reeling to a certain length, the electromagnetic wire can be pressed on the surface of the reel drum when reeling, and then the X-axis linear module can be started, and at this time, the pressure rod can be driven to withdraw the reel drum when reeling to wait for the next reel change.

[0011] Preferably, a group of crimping rollers are provided above the stacking position, and both ends of the crimping rollers are mounted on a group of lower pressure cylinder drive ends. When the traction assembly drives the winding drum to rotate from the winding position to the stacking position, the lower pressure cylinder drives the crimping roller to descend to press against the surface of the electromagnetic wire, and after the cutter completes the cutting of the electromagnetic wire, the traction assembly at the stacking position drives the winding drum to continue rotating to complete the winding of the tail section of the electromagnetic wire, and then continues to drive the wound winding drum to move closer to the rotation center of the installation side frame.

[0012] Preferably, the mounting side frame includes a fixed frame, a rotating frame 1 and a rotating frame 2, the rotating frame 1 and the rotating frame 2 are circular disks distributed in parallel and fixedly connected by a connecting rod, the rotating frame 1 and the rotating frame 2 are installed in the fixed frame for transfer, and the rotating plane of the rotating frame 1 is a protruding fixed frame setting, four groups of traction components are installed on the rotating plane of the rotating frame 1 with a radial interval of 90°, the transposition motor is installed on the fixed frame, and its driving end is connected to the rotating frame 2, and the pushing group includes a pushing block guided through the rotating frame 1 and a pushing plate connected to one end of the pushing block and pushed back and forth by a pushing cylinder on the rotating frame 2.

[0013] Preferably, the traction assembly includes a bottom block slidably mounted on the rotating plane of the turret one and driven back and forth by an electric screw, a rotary block transfer-mounted on the side of the bottom block away from the turret one and driven to rotate by a winding motor in the bottom block, one end of the winding drum is provided with a connecting sleeve sleeved outside the rotating block, the side surface of the connecting sleeve is provided with at least two groups of positioning holes along the circumferential direction, a positioning cylinder is installed in the rotating block, and the driving end of the positioning cylinder is connected to a positioning block that passes through the rotating block and is inserted into the positioning hole to position the winding drum;

[0014] Therefore, when positioning the take-up drum on the traction assembly, specifically, first, the connecting sleeve on the take-up drum is placed outside the rotating block, and then the positioning cylinder drives the positioning block to extend out of the rotating block and be inserted into the corresponding positioning hole. At this point, the connecting sleeve can be positioned in both the axial and circumferential directions. When the rotating block rotates, it can drive the take-up drum to rotate and rewind.

[0015] There are also protective push cylinders on the rotating frame 2 that correspond to the traction assemblies one by one. The driving end of the protective push cylinder is equipped with a protective mounting plate connected to four sets of protective rods. The protective rods are guided through the rotating frame 1 to support the four rectangular corners of the bottom block. At this point, during the winding operation, the protective rods can be extended to support the bottom block, thereby avoiding the influence of winding shaking on the stability of the bottom block.

[0016] Preferably, in order to improve the tightness and accuracy of positioning, the end of the rotating block is also provided with a guide rod correspondingly inserted in the center hole of the winding drum, and the cross-section of the guide rod in the direction perpendicular to its axial direction is a rectangular cross-section, so that the guide rod can be directly connected to the winding drum during loading, so that the winding drum is connected to the traction assembly at a specific position. The specific position specifically refers to that the positioning groove of the winding drum is set upward, and the positioning hole of the connecting sleeve can be directly aligned to the positioning block without adjustment. The side of the positioning block facing away from the bottom block is provided with an inclined surface, and multiple groups of inclined surfaces are distributed in a flared shape toward the side of the bottom block. At this point, when the positioning block is pushed, the connecting sleeve can be tightened.

[0017] Preferably, the loading group includes a guide rod aligned with the guide rod of the loading position, multiple groups of winding drums are sleeved on the guide rod, and a push cylinder for pushing the winding drum forward along the guide rod is provided at the end of the guide rod facing away from the traction assembly. A vertex cylinder is also provided on one side of the loading position, and the mounting end of the vertex cylinder is installed at the driving end of a group of pushing linear modules. The vertex cylinder is used to extend when a group of winding drums are pushed to the end of the guide rod by the push cylinder, and under the continuous driving of the push linear module, it blocks the end of the winding drum from the lower side to push the winding drum away from the guide rod and into the outside of the guide rod until the connecting sleeve of the winding drum is sleeved outside the rotating block. By adding a vertex cylinder, a safe movable distance can be ensured between the guide rod and the guide rod, so that the traction assembly can safely drive the winding drum to rotate.

[0018] A coating and pulling method for producing electromagnetic wire, based on the above-mentioned coating and pulling device for producing electromagnetic wire, comprises the following steps:

[0019] First, the loading group transports the take-up drum to the side close to the loading position in sequence, and pushes a group of take-up drums to the traction assembly when the traction assembly rotates to the loading position. After positioning the take-up drum, the traction assembly at the loading position rotates 90° to the take-up position under the drive of the transposition motor. At the take-up position, the head end of the electromagnetic wire is fixed to the take-up drum, and then the traction assembly is started to rotate, so that the electromagnetic wire can be reeled. After the reeling is completed, the take-up drum at the reeling position is driven by the transposition motor to rotate 90° to the stacking position. At the stacking position, the traction assembly drives the take-up drum to move closer to the rotation center of the mounting side frame. At the same time, the second group of take-up drums at the reeling position also reels, and loads the third group of take-up drums at the loading position. After the second group of take-up drums at the reeling position completes reeling, the second group of take-up drums at the reeling position rotates to the stacking position. The first group of winding drums that were originally in the stacking position and have completed the movement toward the center rotates to the empty position. At the same time, the third group of winding drums at the original loading position rotates to the winding position, and the traction assembly at the original empty position rotates to the loading position for the fourth group of winding drums to be loaded again. This process is repeated. When the fourth group of winding drums rotates to the winding position for winding, the third group of winding drums has completed the movement toward the center, and the pushing group is started to push the three groups of stacked winding drums together to separate from the traction assembly and unload them into the storage group. The storage box in the storage group is used to receive the three groups of winding drums fed in and is driven and transported away by the conveyor belt after the reception is completed. The traction assembly that has completed the separation of the winding drums returns to its original position away from the center again, and the traction assembly at the loading position returns to its original position opposite to the loading group to continue waiting for the loading group to load the next stacking and unloading cycle.

[0020] The beneficial effect of the present invention is that: in the present invention, the loading group is used to sequentially transport the winding drum to be wound to the traction assembly rotated to the loading position. After the traction assembly positions the winding drum, it can be driven by the transposition motor to rotate 90° to the winding position. At the winding position, the head end of the electromagnetic wire that has been coated and dried is fixed to the winding drum, and the traction assembly is started to rotate to reel the electromagnetic wire. After the winding is completed, the winding drum at the winding position can be driven by the transposition motor to rotate 90° to the stacking position. At the stacking position, the traction assembly can drive the winding drum to move closer to the rotation center of the mounting side frame. At this time, the second group of winding drums at the winding position is wound, and the third group of winding drums at the loading position are loaded. After the second group of winding drums at the winding position has completed winding, the second group of winding drums at the winding position can be rotated to the stacking position, and the first group of winding drums at the stacking position that has completed moving toward the center rotates to the empty position, and at the same time, the third group of winding drums at the original loading position The traction assembly of the original vacant position rotates to the loading position for the fourth group of winding drums to be loaded again, and this process is repeated. When the fourth group of winding drums rotates to the winding position for winding, the third group of winding drums has completed the operation of approaching the center. At this time, the traction assemblies of the loading position, the stacking position and the vacant position all have a group of winding drums approaching the rotation center, and then the pushing group is started to push the three groups of stacked winding drums together to separate from the traction assembly and unload them into the storage group. The storage box in the storage group is used to receive the three groups of winding drums fed in and is driven by the conveyor belt to be transported away after the receiving is completed, and the traction assembly that has completed the separation of the winding drums returns to its original position away from the center, and the traction assembly at the loading position continues to wait for the loading group to load the material to enter the next stacking and unloading cycle. In this way, not only the automatic traction and reel changing operation after the electromagnetic wire is coated can be realized, but also the direct stacking and storage unloading operation can be realized after the reel is changed, which has a higher degree of automation and saves time and effort.

[0021] The winding drum that has completed winding at the winding position is driven by the position change motor to rotate 90 degrees to the stacking position, and the winding drum to be wound up, which was originally the loading position, is rotated to the winding position. At this time, there is still uncut electromagnetic wire stretched between the winding position and the stacking position, and then the Y-axis linear module is started to make the pressure rod descend. The pressure rod can press the electromagnetic wire until the pressure rod completely enters the positioning groove, and the electromagnetic wire is pressed between the pressure rod and the bottom of the positioning groove. Then the cutter can be started to descend to cut the electromagnetic wire pulled between the winding position and the stacking position. The electromagnetic wire pressed and positioned by the pressure rod can be used as the head end of the electromagnetic wire to be wound. After winding a certain length, the electromagnetic wire can be pressed on the surface of the winding drum when winding, and then the X-axis linear module can be started. At this time, the pressure rod can be driven to withdraw from the winding drum when winding to wait for the next roll change. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] like Figure 1-9 As shown, a coating traction device for electromagnetic wire production, in this embodiment, includes a mounting side frame 1, four groups of traction components 2 uniformly arranged on the mounting side frame 1 along the circumferential direction, the four groups of traction components 2 are driven to rotate by the transposition motor 11 on the mounting side frame 1 to sequentially transpose to the loading position 100, the winding position 200, the stacking position 300, and the vacant position 400, a loading group 8 is arranged on the side of the loading position 100 away from the mounting side frame 1, the loading group 8 is used to drive the winding drum 5 to sequentially load the material onto the traction component 2 at the loading position 100, and when the winding drum 5 rotates to the winding position 200 with the traction component 2 to reel in the electromagnetic wire 6, and after the winding drum 5 completes the winding, the traction component 2 drives the winding drum 5 to rotate to the stacking position 300, and The stacking position 300, the traction assembly 2 is also used to drive the winding drum 5 to move closer to the rotation center of the installation side frame 1, and when the rotation center of the installation side frame 1 moves closer to the three groups of winding drums 5, the pushing group 12 installed on the installation side frame 1 is started to push the three groups of winding drums 5 away from the traction assembly 2 and feed them into the storage group 3. The storage group 3 includes a receiving groove 31 with openings at both ends, a storage box 32 with openings at both ends, and a conveyor 33. The conveyor 33 is arranged in the receiving groove 31, and the feeding end and the unloading end of the conveyor 33 extend to the openings at both ends of the receiving groove 31 respectively. The storage box 32 falls from the through port 34 opened at the top of the receiving groove 31 to the feeding end of the conveyor 33, and one end of the storage box 32 is opened to align with the three groups of winding drums 5 to be separated from the traction assembly 2;

[0036] At this point, the feeding group 8 is used to sequentially convey the winding drum 5 to be wound to the traction assembly 2 that rotates to the feeding position 100. After positioning the winding drum 5, the traction assembly 2 can be driven by the transposition motor 11 to rotate 90° to the winding position 200. At the winding position 200, after the head end of the electromagnetic wire 6 that has been coated and dried is fixed to the winding drum 5, the traction assembly 2 is started to rotate to reel the electromagnetic wire 6. After the winding is completed, the winding drum 5 at the winding position 200 can be driven by the transposition motor 11 to rotate 90° again to the stacking position. 300, at the stacking position 300, the traction assembly 2 can drive the winding drum 5 to move closer to the rotation center of the mounting side frame 1. At this time, the second group of winding drums 5 at the winding position 200 are wound, and the third group of winding drums 5 at the loading position 100 are loaded. After the second group of winding drums 5 at the winding position 200 have finished winding, the second group of winding drums 5 at the winding position 200 can be rotated to the stacking position 300, and the first group of winding drums 5 at the stacking position 300 that have completed moving closer to the center are rotated to the vacant position 400. At the same time, the third group of winding drums at the original loading position 100 are loaded. The winding drum 5 rotates to the winding position 200, and the traction assembly 2 at the original empty position 400 rotates to the loading position 100 to load the fourth group of winding drums 5 again, and this is repeated. When the fourth group of winding drums 5 rotates to the winding position 200 for winding, the third group of winding drums 5 has completed the operation of moving toward the center. At this time, the traction assembly 2 at the loading position 100, the stacking position 300 and the empty position 400 all have a group of winding drums 5 moving toward the rotation center, and then the pushing group 12 is started to push the three groups of stacked winding drums 5 together to separate from the traction assembly 2 and unload them to the storage group 3, the storage box 32 in the storage group 3 is used to receive the three groups of winding drums 5 sent in and is driven and transported away by the conveyor belt after the receiving is completed, and the traction component 2 that completes the separation of the winding drum 5 returns to its original position away from the center again, and the traction component 2 at the loading position 100 continues to wait for the loading of the loading group 8 to enter the next stacking and unloading cycle. At this point, not only the automatic traction and roll changing operation of the electromagnetic wire 6 after coating can be realized, but also the direct stacking and storage unloading operation can be realized after the roll changing, which has a higher degree of automation and is more time-saving and labor-saving.

[0037] A set of cutters 4 is also provided between the winding position 200 and the stacking position 300. The cutters 4 are driven by a cutting cylinder to perform linear reciprocating motion to cut off the electromagnetic wire 6 stretched between the winding position 200 and the stacking position 300 after the winding drum 5 rotates to the stacking position 300 after the winding is completed.

[0038] A group of positioning grooves 51 extending axially through are provided on the winding drum 5, and when the winding drum 5 rotates to the winding position 200, the positioning grooves 51 rotate to the top, and a group of pressure rods 52 are also provided above the positioning grooves 51. The pressure rods 52 are used to press the electromagnetic wire 6 stretched between the winding position 200 and the stacking position 300 into the positioning grooves 51. The cutter 4 is provided above one side of the positioning groove 51 near the center. When the pressure rod 52 completely enters the positioning groove 51 and presses the electromagnetic wire 6 to the bottom of the positioning groove 51, the cutter 4 descends under the drive of the cutting cylinder to cut the electromagnetic wire 6. The surface of the winding drum 5 can also be used as a cutting support surface when the cutter 4 cuts the electromagnetic wire 6. The head end of the cut electromagnetic wire 6 is pressed in the positioning groove 51 by the pressure rod 52, and the tail end can continue to be wound around the outside of the winding drum 5 when the stacking position 300 continues to rotate. At this time, the automatic cutting and reeling operation of the reeling position 200 can be completed, saving the operation of manually reeling and positioning the electromagnetic wire 6, saving time and effort. Moreover, since the pressure rod 52 is completely inserted into the positioning groove 51 when positioned, after the reeling is completed, the pressure rod 52 can be pulled out from one end of the positioning groove 51 to carry out the next pressing cycle.

[0039] One end of the pressure rod 52 is fixed on a set of turntables 53, and the turntables 53 are in turn mounted on a set of positioning side plates 54 and rotated under the drive of the rotary motor 55. The distance between the pressure rod 52 and the rotation center of the turntable 53 is the same as the distance between the pressure rod 52 and the rotation center of the take-up drum 5 when the pressure rod 52 is pressed against the bottom of the positioning groove 51, and the positioning side plates 54 are mounted on the driving end of a set of Y-direction linear modules 56, and the Y-direction linear modules 56 are mounted on the driving end of a set of X-direction linear modules 57. The Y-direction linear modules 56 are used to drive the pressure rod 52 to descend and crimp the electromagnetic wire 6 to the bottom of the positioning groove 51. The rotary motor 55 is used to synchronously rotate the pressure rod 52 to rotate with the take-up drum 5 when the take-up drum 5 is performing the winding operation, and the X-direction linear module 57 is used to drive the pressure rod 52 to axially withdraw from the positioning groove 51 after the head end of the electromagnetic wire 6 on the take-up drum 5 completes the winding positioning.

[0040] At this point, the winding operation can be completed in a fully automated manner. Specifically, first, the winding drum 5 that has completed winding at the winding position 200 is rotated 90 degrees to the stacking position 300 under the drive of the position change motor 11, and the winding drum 5 to be wound that was originally at the loading position 100 is rotated to the winding position 200. At this time, the uncut electromagnetic wire 6 is still stretched between the winding position 200 and the stacking position 300. Then, the Y-axis linear module 56 is started to make the pressure rod 52 descend, and the pressure rod 52 can press the electromagnetic wire 6 until the pressure rod 52 is completely positioned. The electromagnetic wire 6 is in the groove 51, and is pressed between the pressure rod 52 and the bottom of the positioning groove 51. Then, the cutter 4 can be started to descend to cut the electromagnetic wire 6 pulled between the winding position 200 and the stacking position 300. The electromagnetic wire 6 pressed and positioned by the pressure rod 52 can be used as the head end of the electromagnetic wire 6 to be wound. After winding a certain length, the electromagnetic wire 6 can be pressed against the surface of the winding drum 5 when winding. Then, the X-axis linear module 57 can be started. At this time, the pressure rod 52 can be driven to withdraw from the winding drum 5 when winding to wait for the next roll change.

[0041] A group of crimping rollers 7 are also provided above the stacking position 300. Both ends of the crimping rollers 7 are mounted on a group of lower pressure cylinder drive ends. When the traction component 2 drives the winding drum 5 to rotate from the winding position 200 to the stacking position 300, the lower pressure cylinder drives the crimping roller 7 to descend to press against the surface of the electromagnetic wire 6. After the cutter 4 completes the cutting of the electromagnetic wire 6, the traction component 2 of the stacking position 300 drives the winding drum 5 to continue rotating to complete the winding of the tail section of the electromagnetic wire 6, and then continues to drive the wound winding drum 5 to move closer to the rotation center of the installation side frame 1.

[0042] The mounting side frame 1 includes a fixed frame 13, a rotating frame 14 and a rotating frame 2 15. The rotating frame 14 and the rotating frame 2 15 are circular disks distributed in parallel and are fixedly connected by a connecting rod. The rotating frame 14 and the rotating frame 2 15 are installed in the fixed frame 13 for transfer, and the rotation plane of the rotating frame 14 is protruding from the fixed frame 13. Four groups of traction components 2 are slidingly installed on the rotation plane of the rotating frame 14 at radial intervals of 90°. The transposition motor 11 is installed on the fixed frame 13, and its driving end is connected to the rotating frame 2 15. The pushing group 12 includes a pushing block 121 that guides through the rotating frame 14 and a pushing plate 122 that is connected to one end of the pushing block 121 and is pushed back and forth by the pushing cylinder on the rotating frame 2 15.

[0043] The traction assembly 2 includes a bottom block 22 that is slidably mounted on the rotating plane of the turret 14 and driven back and forth by the electric screw 21, a rotating block 23 that is transfer-mounted on the side of the bottom block 22 away from the turret 14 and driven to rotate by the winding motor in the bottom block 22, one end of the winding drum 5 is provided with a connecting sleeve 58 that is sleeved on the outside of the rotating block 23, and the side surface of the connecting sleeve 58 is provided with at least two groups of positioning holes 59 along the circumferential direction. A positioning cylinder 24 is installed in the rotating block 23, and the driving end of the positioning cylinder 24 is connected to a positioning block 25 that passes through the rotating block 23 and is inserted into the positioning hole 59 to position the winding drum 5;

[0044] Therefore, when positioning the take-up drum 5 on the traction assembly 2, specifically, first, the connecting sleeve 58 on the take-up drum 5 is placed outside the rotating block 23, and then the positioning cylinder 24 drives the positioning block 25 to extend out of the rotating block 23 and be inserted into the corresponding positioning hole 59. At this point, the connecting sleeve 58 can be positioned in both the axial and circumferential directions. When the rotating block 23 rotates, the take-up drum 5 can be driven to rotate for winding.

[0045] There are also protective push cylinders 16 on the rotating frame 2 15 that correspond one-to-one with the traction components 2. The driving end of the protective push cylinder 16 is equipped with a protective mounting plate connected to four sets of protective rods 17. The protective rods 17 are guided through the rotating frame 1 14 to support the four rectangular corners of the bottom block 22. At this point, during the winding operation, the protective rods 17 can be extended to support the bottom block 22, thereby avoiding the influence of winding shaking on the stability of the bottom block 22.

[0046] In order to improve the tightness and accuracy of positioning, the end of the rotating block 23 is also provided with a guide rod 26 that is correspondingly inserted into the center hole of the winding drum 5. The cross-section of the guide rod 26 in the direction perpendicular to its axial direction is a rectangular cross-section. Therefore, when loading, the guide rod 26 can be directly connected to the winding drum 5, so that the winding drum 5 is connected to the traction assembly 2 in a specific position. This specific position specifically refers to that the positioning groove 51 of the winding drum 5 is set upward, and the positioning hole 59 of the connecting sleeve 58 can be directly aligned with the positioning block 25 without adjustment. The side of the positioning block 25 facing away from the bottom block 22 is provided with an inclined surface 27, and multiple groups of inclined surfaces 27 are distributed in a flared shape toward the side of the bottom block 22. At this point, when pushing the positioning block 25, the connecting sleeve 58 can be tightened.

[0047] The loading group 8 includes a guide rod 81 that is aligned with the guide rod 26 of the loading position 100. Multiple groups of winding drums 5 are sleeved on the guide rod 81, and the end of the guide rod 81 facing away from the traction assembly 2 is provided with a push cylinder 82 for pushing the winding drum 5 forward along the guide rod 81. A vertex cylinder 83 is also provided on one side of the loading position 100. The mounting end of the vertex cylinder 83 is installed at the driving end of a group of pushing linear modules 84. The vertex cylinder 83 is used to extend when a group of winding drums 5 are pushed to the end of the guide rod 81 by the push cylinder 82, and under the continuous driving of the pushing linear module, it blocks the end of the winding drum 5 to push the winding drum 5 away from the guide rod 81 and into the outside of the guide rod 26 until the connecting sleeve 58 of the winding drum 5 is sleeved on the outside of the rotating block 23. By adding the vertex cylinder 83, a safe movable distance can be ensured between the guide rod 81 and the guide rod 26, so that the traction assembly 2 can safely drive the winding drum 5 to rotate.

[0048] Example 2

[0049] A coating and pulling method for producing electromagnetic wire, based on the above-mentioned coating and pulling device for producing electromagnetic wire, in this embodiment, comprises the following steps:

[0050] First, the loading group 8 sequentially transports the winding drum 5 to the side close to the loading position 100, and pushes a group of winding drums 5 onto the traction assembly 2 when the traction assembly 2 rotates to the loading position 100. After the traction assembly 2 at the loading position 100 positions the winding drum 5, it rotates 90° to the winding position 200 under the drive of the position change motor 11. At the winding position 200, after the head end of the electromagnetic wire 6 is fixed to the winding drum 5, the traction assembly 2 is started to rotate automatically to start the winding of the electromagnetic wire 6. After the winding is completed, the winding drum 5 at the winding position 200 is driven by the transposition motor 11 to rotate 90 degrees to the stacking position 300. At the stacking position 300, the traction component 2 drives the winding drum 5 to move closer to the rotation center of the mounting side frame 1. At the same time, the second group of winding drums 5 at the winding position 200 also winds up, and the third group of winding drums 5 at the loading position 100 are loaded. After the second group of winding drums 5 at the winding position 200 have finished winding, the second group of winding drums 5 at the winding position 200 rotates The first group of winding drums 5 originally at the stacking position 300 and having completed the process of moving toward the center rotates to the empty position 400. At the same time, the third group of winding drums 5 originally at the loading position 100 rotates to the winding position 200, and the traction assembly 2 originally at the empty position 400 rotates to the loading position 100 to load the fourth group of winding drums 5 again. This is repeated. When the fourth group of winding drums 5 rotates to the winding position 200 for winding, the third group of winding drums 5 has completed the process of moving toward the center, and the process starts. The dynamic pushing group 12 pushes the three groups of stacked reels 5 together to separate them from the traction assembly 2 and unload them into the storage group 3. The storage box 32 in the storage group 3 is used to receive the three groups of reels 5 fed in and is driven and transported away by the conveyor belt after the receiving is completed. The traction assembly 2 that has completed the separation of the reels 5 returns to its original position away from the center again, and the traction assembly 2 at the loading position 100 returns to its original position opposite to the loading group 8 to continue waiting for the loading of the loading group 8 to start the next stacking and unloading cycle.
