Description

Technical Field

[0001] The invention relates to the field of coil production equipment, and in particular to a winding device with a mandrel. Background Art

[0002] When a coil winding device in the prior art is winding a coil, the wire to be wound is generally fixed by a rotating winding spindle. There are various ways of fixing, one of which is to penetrate the skeleton through the free end of the winding spindle. However, this fixing method is suitable for skeletons with shorter lengths. If the skeleton is longer, it is difficult for the skeleton to maintain balance on the winding spindle. When the winding spindle drives the skeleton to rotate, one end of the skeleton may tilt, resulting in uneven winding of the coil, thereby affecting the performance and use of the coil. Summary of the invention

[0003] The main purpose of the present invention is to provide a winding device with a central mandrel to ensure the stability of the frame during the winding process.

[0004] In order to achieve the above-mentioned main purpose, the winding device with a push rod provided by the present invention includes a rotating spindle assembly and a push rod assembly, the rotating spindle assembly includes multiple rotating spindles and a spindle driving assembly, the spindle driving assembly drives the rotation and translation of the rotating spindle; the push rod assembly includes multiple push rods and a push rod driving assembly, the push rod driving assembly drives the push rod to rotate, and the push rod driving assembly drives the push rod to move toward or away from the rotating spindle assembly and translate, a clamping position is arranged between the rotating spindle and the push rod, the rotating spindle, the clamping position and the push rod are arranged colinearly along the axial direction of the rotating spindle, and the rotating spindle and the push rod rotate synchronously.

[0005] It can be seen from the above scheme that before winding, the push rod driving assembly drives to move toward the rotating spindle, the push rod and the rotating spindle clamp the skeleton to be wound in the clamping position, and the rotating spindle and the push rod rotate synchronously to carry out winding on the skeleton. The push rod and the rotating spindle respectively contact the two ends of the skeleton along the length direction of the skeleton, so that the push rod and the rotating spindle clamp the skeleton, ensuring that the position of the longer skeleton is fixed during the winding process, and ensuring the stability of the skeleton, so that the winding is uniform and the winding effect is better.

[0006] A further solution is that the free end of the push rod is connected to a first clamping block, a first fixing groove is arranged on the side wall of the first clamping block facing the rotating main shaft, at least two avoidance grooves are arranged on the side wall of the first fixing groove, and the two avoidance grooves are arranged opposite to each other and in a collinear manner.

[0007] It can be seen that when the push rod and the rotating spindle clamp the skeleton, one end of the skeleton is located in the first fixed groove, which increases the contact area between the skeleton and the first clamping block, so that the push rod can clamp the skeleton to be wound more firmly with the rotating spindle, wherein the avoidance groove on the side wall of the first fixed groove can be used to avoid the protruding structure on the skeleton, so that the structure of the first fixed groove is further close to the structure on one end of the skeleton, thereby being able to better clamp the skeleton.

[0008] A further solution is that a accommodating cavity is provided in the push rod, a first spring and a pressure rod are provided in the accommodating cavity, the first spring abuts against the axial first ends of the push rod and the pressure rod, the axial second end of the pressure rod passes through the accommodating cavity, the accommodating cavity is connected to the first fixed groove, and the axial second end of the pressure rod is located in the first fixed groove.

[0009] It can be seen that when the push rod and the rotating spindle clamp the skeleton, the skeleton squeezes the axial second end of the pressure rod in the first fixed groove, and the first spring is compressed. The compression of the first spring provides a buffering force for the skeleton to prevent the skeleton from being damaged due to excessive force when the push rod and the rotating spindle clamp the skeleton.

[0010] A further solution is that the rotating main shaft includes a fixed shaft, an installation shaft, a connecting block and a second spring. The fixed shaft and the installation shaft are connected along the axial direction of the rotating main shaft. The connecting block is connected to the fixed shaft. The second spring is sleeved outside the fixed shaft, and the second spring abuts between the connecting block and the installation shaft.

[0011] It can be seen that when the installation shaft on the rotating spindle contacts the frame to be wound, the frame drives the installation shaft to compress the second spring. The compression of the second spring provides a buffering force for the frame to prevent the frame from being damaged due to excessive force when the push rod and the rotating spindle clamp the frame.

[0012] A further solution is that a second clamping block is connected to one end of the fixed shaft toward the push rod assembly, a first fixed block, a second fixed block, a third fixed block and a fourth fixed block are arranged on the side wall of the second clamping block toward the push rod assembly, a second fixed groove is arranged between the first fixed block and the second fixed block, the third fixed block is respectively connected to the first fixed block and the second fixed block, a first clamping groove is formed between the third fixed block and the first fixed block, the fourth fixed block is respectively connected to the first fixed block and the second fixed block, and a second clamping groove is formed between the fourth fixed block and the second fixed block.

[0013] It can be seen that the first clamping block is provided with a first clamping groove and a second clamping groove to position the frame, further enhancing the stability of the frame when it is clamped.

[0014] A further solution is that the rotating spindle assembly includes a locking assembly, the locking assembly includes a locking rod, a plurality of pins and a locking drive assembly, the plurality of pins are arranged equidistantly along the axial direction of the locking rod; a locking plate is connected to one end of the rotating spindle, the locking plate is provided with a plurality of locking grooves equidistantly along the circumference of the locking plate, the locking drive assembly drives the pin to pass through the locking groove, and one pin corresponds to one rotating spindle.

[0015] It can be seen that after the rotating spindle stops rotating, the locking drive assembly drives the pin to pass through the locking slot. Since the locking plate is connected to the rotating spindle, the locking slot is locked by the pin to lock the rotating spindle, thereby preventing the rotating spindle from rotating during the clamping frame.

[0016] A further solution is that the winding device includes a loading and unloading assembly, the loading and unloading assembly includes a discharge block and a material block driving assembly, the material block driving assembly drives the discharge block to move in the vertical and horizontal directions; a plurality of loading troughs and a plurality of unloading troughs are arranged on the discharge block, and a unloading trough is arranged between two adjacent loading troughs.

[0017] It can be seen that the upper chute and the lower chute are concentrated on one discharge block, which can effectively simplify the structure of the device and effectively save the space occupied by the device.

[0018] A further solution is that the material block driving assembly includes a mounting block, a first cylinder and a second cylinder, the material discharge block is set on the mounting block, the first cylinder drives the mounting block to move, and the second cylinder drives the mounting block and the first cylinder to move at the same time, and the driving stroke of the first cylinder is smaller than the driving stroke of the second cylinder.

[0019] It can be seen that since the driving stroke of the first cylinder is smaller than the driving stroke of the second cylinder, when the material block driving assembly drives the discharge block to move, the second cylinder is first used to drive the mounting block and the discharge block to move a larger stroke, and then the first cylinder is used to fine-tune the movement displacement of the discharge block, so that the movement displacement of the discharge block is more precise.

[0020] A further solution is that the winding device includes a wire clamping assembly, the wire clamping assembly includes a plurality of clamp assemblies and a wire clamping drive assembly, and the wire clamping drive assembly drives the clamp assembly to move; a clamp assembly is arranged between two adjacent rotating spindles.

[0021] It can be seen that the clamp assembly can be used to clamp the wire ends of the wire before the skeleton is wound, and after the winding is completed, the wire can be pulled apart by driving the clamp assembly to move through the wire clamping drive assembly.

[0022] A further solution is that the clamp assembly includes a first wire clamping block, a second wire clamping block and a wire clamping drive device, the first wire clamping block is provided with a wire clamping end, a hinged portion and a connecting end, the hinged portion is arranged between the wire clamping end and the connecting end, the hinged portion is hinged to the second wire clamping block, the wire clamping drive device is connected to the connecting end, and the wire clamping drive device drives the wire clamping end of the first wire clamping block to move toward or away from the second wire clamping block.

[0023] It can be seen that the wire clamping drive device drives the connecting end of the first wire clamping block to move back and forth. Since the hinged end of the first wire clamping block is hinged to the second wire clamping block, the wire clamping end of the first wire clamping block moves toward or away from the second wire clamping block, thereby clamping the wire.

[0037] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0038] The winding device with a mandrel of the present invention can be used for the winding process of the windings of the electronic components in the electrical appliances, and the electronic components in the electrical appliances can be, for example, transformers. The winding device with a mandrel of the present invention can clamp a long skeleton through the mandrel assembly and the rotating spindle assembly, and the mandrel and the rotating spindle rotate synchronously to wind the skeleton. After the winding is completed, the clamp assembly pulls the wire to complete the winding. In the above winding process, the skeleton is clamped by the mandrel and the rotating spindle, so that the skeleton is more stable during the winding process and the winding is more uniform.

[0039] See also Figure 1 The winding device with a mandrel comprises a mounting platform 1, a loading and unloading assembly 2, a horizontal attenuation assembly 3, a wire nozzle assembly 4, a rotating spindle assembly 5, a mandrel assembly 6 and a wire clamping assembly 7, and the loading and unloading assembly 2, the horizontal attenuation assembly 3, the rotating spindle assembly 5, the mandrel assembly 6 and the wire clamping assembly 7 are arranged on the mounting platform 1. In this embodiment, along the vertical direction, the horizontal attenuation crime is arranged above the rotating spindle assembly 5, the wire nozzle assembly 4 is arranged between the horizontal attenuation assembly 3 and the rotating spindle assembly 5, and the loading and unloading assembly 2, the rotating spindle assembly 5, the wire clamping assembly 7 and the mandrel assembly 6 can be arranged on the same horizontal plane; when the rotating spindle assembly 5 and the mandrel assembly 6 clamp the skeleton to be wound, the loading and unloading assembly 2 is located between the rotating spindle assembly 5 and the mandrel assembly 6.

[0040] See also Figure 2The upper and lower material assembly 2 includes a material discharging block 21 and a material block driving assembly 22, and the material block driving assembly 22 drives the material discharging block 21 to move in the vertical direction and the horizontal direction. A plurality of upper material troughs 23 and a plurality of lower material troughs 24 are arranged on the material discharging block 21, and a lower material trough 24 is arranged between every two adjacent upper material troughs 23. The upper material troughs 23 and the lower material troughs 24 are arranged crosswise with each other, and the positions of the upper material troughs 23 and the lower material troughs 24 are closer, which makes it easier to adjust the loading and unloading modes, and the upper material troughs 23 and the lower material troughs 24 are concentrated on one material discharging block 21, which can effectively simplify the structure of the device and effectively save the space occupied by the device. In this embodiment, the structure of the upper chute 23 is the same as that of the lower chute 24. The upper chute 23 is provided with a first opening 231, a second opening 232 and a third opening 233. The first opening 231 is provided between the second opening 232 and the third opening 233. The first opening 231 is located at the top of the upper chute 23. The second opening 232 and the third opening 233 are respectively located on two opposite sides of the upper chute 23. When manually loading the skeleton, the skeleton is placed in the upper chute 23 through the first opening 231, and the two ends of the skeleton along the length direction of the skeleton respectively pass through the second opening 232 and the third opening 233. The loading chute 23 includes two avoidance grooves 234 and three limiting grooves 235. An avoidance groove 234 is arranged between every two limiting grooves 235. Along the width direction of the loading chute 23, the width of the avoidance groove 234 is greater than the width of the limiting groove 235. The operator can more quickly take and place the skeleton in the loading chute 23 by setting the avoidance groove 234 with a larger width. The side wall of the limiting groove 235 can be adjacent to the side wall of the skeleton. The setting of the limiting groove can make the skeleton have only one posture in the loading chute 23, so that the rotating spindle assembly 5 and the push rod assembly 6 can clamp the skeleton more accurately.

[0041] The material block driving assembly 22 includes a mounting block 221, a first cylinder 222, a second cylinder 223 and a material block lifting cylinder 224. The material discharge block 21 is arranged on the mounting block 221. The first cylinder 222 drives the mounting block 221 to move. The second cylinder 223 drives the mounting block 221 and the first cylinder 222 to move at the same time. The driving stroke of the first cylinder 222 is smaller than the driving stroke of the second cylinder 223. Since the driving stroke of the first cylinder 222 is smaller than the driving stroke of the second cylinder 223, when the material block driving assembly 22 drives the material discharge block 21 to move, the second cylinder 223 first drives the mounting block 221 and the material discharge block 21 to move a larger stroke, and then the first cylinder 222 fine-tunes the displacement of the material discharge block 21, so that the displacement of the material discharge block 21 is more accurate. The material block lifting cylinder 224 drives the mounting block 221 to move vertically upward.

[0042] When the rotating spindle assembly 5 and the push rod assembly 6 rotate synchronously to wind the skeleton, the horizontal attenuation assembly 3 is used to compress the wire in the wire roll and then convey the wire, so that the length of the wire between the horizontal attenuation assembly 3 and the rotating spindle assembly 5 is increased, and the tension of the wire is reduced.

The pressing drive device 313 is used to drive the pressing block 312 to move toward or away from the top plate 30 along the first direction X. In this embodiment, the first direction X is parallel to the vertical direction. The number of pressing blocks 312 depends on the number of rotating spindles in the rotating spindle assembly 5. In this embodiment, one pressing block 312 corresponds to one wire and one rotating spindle.

[0045] In the embodiment, the top plate 30 is arranged above the support plate 311, and the wire pressing driving device 313 is arranged on the side wall of the support plate 311 away from the top plate 30. The wire pressing driving device 313 drives the pressing block 312 to move toward the top plate 30, and the pressing block 312 passes through the support plate 311. The top plate 30 and the support plate 311 are in the shape of long strips, and the length direction of the support plate 311 is the same as the length direction of the top plate 30. The two ends of the support plate 311 along the length direction of the support plate 311 are respectively connected to the third mounting bar 343 and the fourth mounting bar 344; the width direction of the top plate 30 is parallel to the second direction Y, and the first direction X is perpendicular to the second direction Y. A plurality of pressing blocks 312 are arranged equidistantly along the length direction of the support plate 311.

After the wire passes through a guide hole 322, between the top plate 30 and the pressing block 312, and another guide hole 322 in sequence, the wire moves to the rotating spindle assembly 5 for winding, and the guide hole 322 guides the direction in which the wire moves, so that the pressing block 312 can accurately press the wire, and better set the relative position of one wire corresponding to one pressing block 312 and one rotating spindle.

[0047] The wire pulling assembly 33 drives the wire pressing assembly 31 to move along the second direction Y.

In the present embodiment, the wire pressing driving device 313 and the wire pulling driving device 333 are both cylinders.

[0048] During the winding process, the wire passes between the top plate 30 and the pressure block 312, and the wire pressing drive device 313 drives the pressure block 312 to move, clamping the wire between the top plate 30 and the pressure block 312, and the wire pulling assembly 33 drives the wire pressing assembly 31 to move, thereby increasing the length of the wire between the pressure block 312 and the rotating spindle, thereby adjusting the tightness of the wire, reducing the tightness of the wire being stretched, and ensuring the coordination between the moving speed of the wire and the winding speed of the rotating spindle to improve the production efficiency of the coil; after the wire pulling assembly 33 drives the top plate 30 and the wire pressing assembly 31 that clamp the wire to move to the desired position, the wire pressing drive device 313 drives the pressure block 312 to move away from the top plate 30 to release the wire, and the wire pulling assembly 33 drives the top plate 30 and the wire pressing assembly 31 that clamp the wire to move and reset to perform the next wire feeding action.

A plug hole 611 is arranged on the axial second end of the mandrel 61. The latch driving device 633 drives the latch 632 to insert into the plug hole 611. Before the mandrel 61 is clamped with the rotating spindle, the latch driving assembly 63 drives the latch 632 to insert into the mandrel 61, which can prevent the mandrel 61 from rotating and can clamp the frame with the rotating spindle more accurately and firmly. In this embodiment, since the mandrel 61 rotates synchronously with the rotating spindle in the rotating spindle assembly 5 after clamping the skeleton, the mandrel assembly 6 includes a mandrel rotating assembly 64, which includes a rotating motor, a plurality of transmission wheels 641 and a transmission belt 642.

[0053] The latch assembly 63 further includes a plurality of guide rods 65, which are arranged in parallel along the second direction, and the guide rods 65 are connected to the second mounting block 631. A guide rod mounting block 651 is arranged on the top of the first mounting block 624, and the guide rods 65 penetrate the guide rod mounting block 651. Since the latch driving device 633 drives the latch 632 to move, the setting of the guide rods 65 guides the movement of the latch 632. The guide rods 65 are located above the top rod rotating assembly 64.

[0054] See also Figure 7 Another embodiment of the guide structure of the latch 632 in the latch assembly 63 is as follows: the latch driving device 633 is arranged on the side wall of the second mounting block 631 away from the first mounting block 624, a fixing block 652 is arranged on the side wall of the second mounting block 631 facing the first mounting block 624, a fixing groove 653 is arranged on the top of the first mounting block 624, one end of the fixing block 652 is fixed in the fixing groove 653, and the fixing block 652 is connected to the driving rod of the latch driving device 633.

In this embodiment, the first fixed groove 661 is formed by connecting four connecting plates 662. At least two avoidance grooves 663 are provided on the side wall of the first fixed groove 661, and the two avoidance grooves 663 are arranged oppositely and in a colinear manner.

[0057] When the push rod 61 and the rotating spindle assembly 5 clamp the skeleton, one end of the skeleton is located in the first fixed groove 661, increasing the contact area between the skeleton and the first clamping block 66, so that the push rod 61 can more firmly clamp the skeleton to be wound with the rotating spindle, wherein the avoidance groove 663 on the side wall of the first fixed groove 661 can be used to avoid the protruding structure on the skeleton, so that the structure of the first fixed groove 661 is further close to the structure on one end of the skeleton, so that the skeleton can be clamped better. The skeleton squeezes the axial second end of the pressure rod 666 in the first fixed groove 661, and the first spring 665 is compressed. The compression of the first spring 665 provides a buffering force for the skeleton, so as to prevent the skeleton from being damaged due to excessive force when the push rod 61 and the rotating spindle clamp the skeleton.

[0059] See also Fig.11 The rotating main shaft 51 includes a fixed shaft 511, a mounting shaft 512, a connecting block 513 and a second spring 514. The fixed shaft 511 and the mounting shaft 512 are connected along the axial direction of the rotating main shaft 51. The connecting block 513 is connected to the fixed shaft 511. The second spring 514 is sleeved outside the fixed shaft 511, and the second spring 514 abuts between the connecting block 513 and the mounting shaft 512. When the mounting shaft 512 on the rotating main shaft 51 contacts the wire-winding skeleton, the skeleton drives the mounting shaft 512 to move and drives the connecting block 513 to compress the second spring 514. The compression of the second spring 514 provides a buffering force for the skeleton to prevent the skeleton from being damaged due to excessive force when the top rod 61 and the rotating main shaft 51 clamp the skeleton.

[0060] The fixed shaft 511 is connected to one end of the push rod assembly 6 with a second clamping block 54. The second clamping block 54 is provided with a first fixing block 541, a second fixing block 542, a third fixing block 543 and a fourth fixing block 544 on the side wall facing the push rod assembly 6. The first fixing block 541 and the second fixing block 542 are arranged opposite to each other, and the third fixing block 543 and the fourth fixing block are arranged opposite to each other. A second fixing groove 545 is arranged between the first fixing block 541 and the second fixing block 542. The third fixing block 543 is connected to the first fixing block 541 and the second fixing block 542 respectively. A first clamping groove 546 is formed between the third fixing block 543 and the first fixing block 541. The fourth fixing block 544 is connected to the first fixing block 541 and the second fixing block 542 respectively. A second clamping groove 547 is formed between the fourth fixing block 544 and the second fixing block 542. The second clamping block 54 is provided with a first clamping groove 546 and a second clamping groove 547 to position the skeleton, further enhancing the stability of the skeleton when it is clamped.

[0061] The rotating spindle assembly 5 also includes a locking assembly 53, which is arranged at the axial free end of the rotating spindle 51 away from the push rod assembly 6. The locking assembly 53 includes a locking rod 531, a plurality of plug rods 532 and a locking driving assembly 533. The plurality of plug rods 532 are arranged equidistantly along the axial direction of the locking rod 531. A locking plate 515 is connected to one end of the rotating spindle 51. The locking plate 515 is provided with a plurality of locking grooves 516 equidistantly along the circumference of the locking plate 515. The locking driving assembly 533 drives the plug rod 532 to pass through the locking groove 516. One plug rod 532 corresponds to one rotating spindle 51. After the rotating spindle 51 stops rotating, the locking driving assembly 533 drives the plug rod 532 to pass through the locking groove 516. Since the locking plate 515 is connected to the rotating spindle 51, the locking of the locking groove 516 by the plug rod 532 realizes the locking of the rotating spindle 51, which can prevent the rotating spindle 51 from rotating during the process of clamping the frame.

[0062] In this embodiment, the locking drive assembly 533 includes a locking frame 534, a locking cylinder 535 and a hinged rod. The two ends of the locking rod 531 along the axial direction of the locking rod 531 are arranged on the locking frame 534. The axial first end of the hinged rod is fixedly connected to the locking rod 531, and the axial second end of the hinged rod is hingedly connected to the driving rod of the locking cylinder 535. When the driving rod of the locking cylinder 535 moves forward, the axial second end of the hinged rod is hingedly connected to the driving rod of the locking cylinder 535, so that the axial second end of the hinged rod rotates, driving the locking rod 531 to rotate on the locking frame 534, thereby driving the insertion rod 532 to enter or exit the locking groove 516, thereby locking the rotating main shaft 51 to prevent the rotating main shaft 51 from rotating when the rotating main shaft 51 and the push rod 61 clamp the skeleton.

[0063] See also Fig.12The clamp assembly 7 includes a plurality of clamp assemblies 71 and a clamp drive assembly 72, and the clamp drive assembly 72 drives the clamp assembly 71 to move. In this embodiment, the clamp drive assembly drives the clamp assembly through a plurality of cylinders or motors and a lead screw to achieve movement in multiple directions such as up, down, left, right, front and back. A clamp assembly 71 is arranged between two adjacent rotating spindles 51. The clamp assembly 71 can be used to clamp the wire end of the wire before the skeleton is wound, and the wire can be pulled off by driving the clamp assembly 71 to move through the clamp drive assembly 72 after the winding is completed.

[0064] See also Fig.13 In this embodiment, the clamp assembly 71 includes a first clamp block 73, a second clamp block 74 and a clamp drive device 75. The first clamp block 73 is provided with a clamp end 731, a hinged portion 732 and a connecting end 733. The hinged portion 732 is provided between the clamp end 731 and the connecting end 733. The hinged portion 732 is hinged to the second clamp block 74. The clamp drive device 75 is connected to the connecting end 733. The clamp drive device 75 drives the clamp end 731 of the first clamp block 73 to move toward or away from the second clamp block 74. The clamp drive device 75 drives the connecting end 733 of the first clamp block 73 to move back and forth. Since the hinged portion 732 of the first clamp block 73 is hinged to the second clamp block 74, the clamp end 731 of the first clamp block 73 moves toward or away from the second clamp block 74, thereby clamping the wire.

[0065] When the winding device starts working, the operator manually places the skeleton in the feeding trough 23, and the movement of the discharge block 21 cooperates with the movement of the push rod 61 and the rotating spindle 51 to clamp the skeleton in the feeding trough 23, and drives the skeleton to move to the side of the clamp assembly 71. During the first winding, the operator moves the wire from the wire coil through the horizontal attenuation assembly 3, passes through the wire nozzle 411 on the wire nozzle cross beam 41, and clamps the wire end of the wire in the clamp assembly 71. Under the guidance of the wire nozzle 411, the wire is wound around the skeleton, and the push rod 61 rotates synchronously with the rotating spindle 51 to start winding. After the winding is completed, the clamp assembly 71 moves to tear off the wire or use the cutter 412 on the wire nozzle cross beam 41 to cut it off, and the push rod assembly 6 and the rotating spindle 51 drive the completed winding coil to the unloading trough 24, and the operator manually takes out the coil in the unloading trough 24, thereby completing the unloading.
