Description

TECHNICAL FIELD

[0001] The present application relates to a winding device, in particular to a wire head shoveling mechanism and a winding foot hanging mechanism with the same. BACKGROUND

[0002] After winding a coil on a closed magnetic core, a wire head cannot be formed at the starting end of the coil because the wire is automatically wound into a coil after passing through the arc-shaped winding channel of the winding jig, and each coil abuts against each other, thus the starting end also forms a coil and abuts against the adjacent coil. At the end of the coil, since the end is the wire feeding end, the cutting position of the wire cutting mechanism can be controlled to form the end wire head.

[0003] The closed magnetic core with the wound coil usually needs to be assembled with a plastic skeleton to form an electromagnetic component such as an inductor or a transformer, and the plastic skeleton has a conductive pin. After assembly, both ends (the starting end and the end) of the coil need to be wound on the conductive pin (i.e. the "foot hanging process"), and finally the electrical connection is formed by soldering to facilitate the installation of the electromagnetic component on various circuit boards through the conductive pin.

[0004] Therefore, in the related art, the automatic winding device can form a wire head at the end of the coil after winding the coil on the closed magnetic core, but cannot form a wire head at the starting end. Without the wire head, it is difficult to continuously wind the wire head of the coil on the pin of the skeleton in the subsequent foot hanging process. Generally, the wound coil (including the closed magnetic core) in the winding device needs to be unloaded and taken out, and then the starting end of the coil is manually pulled out to form a wire head, and then it is fed to the foot hanging device for foot hanging. In this process, since the wire head needs to be manually pulled out, the winding process and the foot hanging process are interrupted and cannot be continuously performed, thereby greatly reducing the production efficiency. In addition, the length of the wire head pulled out by the manual is not uniform, which is not conducive to the reliable performance of the foot hanging process. SUMMARY

[0081] The splicing mechanism of the line head of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0082] Referring to Figures 1-2 As shown, the closed magnetic core 401 is a generally rectangular structure, the closed magnetic core 401 has two parallel edge columns 4011, the upper ends of the two edge columns 4011 are connected by a first closed portion 4012, that is, the upper ends of the two edge columns 4011 are closed by the first closed portion 4012, the lower ends of the two edge columns 4011 are connected by a second closed portion 4013, that is, the lower ends of the two edge columns 4011 are closed by the second closed portion 4013, the two edge columns 4011, the first closed portion 4012 and the second closed portion 4013 are generally formed as an integral structure. The edge column 4011 is used for winding the coil 402, and the coil 402 can be wound on one edge column 4011, or the coil 402 can be wound on two edge columns 4011 respectively.

[0083] Referring to Figures 3-11 As shown, according to the splicing mechanism of the line head provided by the embodiment of the present application, the line head D4b wound on the coil 402 on the closed magnetic core 401 is separated, the splicing mechanism of the line head includes a clamping jig 10, a coil pressing device 20 and a splicing device 30.

[0084] Specifically, the loading fixture 10 has a clamping groove H10 adapted to clamp the second closed part 4013 of the closed magnetic core 401. The clamping groove H10 is exemplarily a shallow groove having an open state and a clamped state, and can be switched between the two states. In specific use, after winding, the closed magnetic core 401 with the coil 402 (i.e., “magnetic core coil 40”) can be inserted into the clamping groove H10 in the open state, and the clamping groove H10 can be switched from the open state to the clamped state, so that the second closed part 4013 of the closed magnetic core 401 can be clamped by the clamping groove H10.

[0085] The coil pressing device 20 is arranged above the loading fixture 10, and is used to press the coil 402 on the closed magnetic core 401 downward. Since the closed magnetic core 401 is arranged in the clamping groove H10 in the vertical state, the coil pressing device 20 can press the topmost coil of the coil 402 along the axis of the coil 402. It can be understood that when the coil pressing device 20 presses the topmost coil of the coil 402, the upper end of the coil 402 as part of the wire end D4b cannot be pressed, so that the shoveling device 30 can shovel the part of the wire end D4b upward.

[0086] The shoveling device 30 is arranged on one side of the loading fixture 10. The shoveling device 30 includes a shovel 301 and a first driver 302 connected with the shovel 301, and is used to drive the shovel 301 to move along the X-axis direction to the direction close to the coil 402 after the coil 402 is pressed by the coil pressing device, so as to be inserted below the wire end D4b at the upper end of the coil 402, and make the wire end D4b at the upper end of the coil 402 be raised upward.

[0087] According to the wire end shoveling mechanism provided by the embodiment of the present application, after winding, the closed magnetic core 401 with the coil 402 is transferred to the loading fixture 10, clamped by the loading fixture 10, pressed downward along the axis by the coil pressing device 20, and finally the shovel 301 is driven by the first driver 302 to move along the X-axis direction to the direction close to the coil 402, and is inserted below the wire end D4b at the upper end of the coil 402, so that the wire end D4b at the upper end of the coil 402 is raised upward. In this way, the wire end D4b at the upper end of the coil 402 after winding can be automatically processed, the processing process is not interrupted by manually pulling the wire end D4b, the subsequent foot hanging process can be connected, full-automatic processing is realized, the production and processing efficiency is significantly improved, and the length and direction of the automatically formed wire end D4b are consistent, which can ensure that the subsequent foot hanging process is more orderly and smoothly.

[0088] Reference Figures 5-7As shown, in one embodiment of the present application, the coil pressing device 20 comprises a multi-axis robot arm 203, a pressing head 201 and at least one elastic needle 202, the multi-axis robot arm 203 is capable of moving along multiple axes, for example, moving along the X-axis, Y-axis and Z-axis. The pressing head 201 is arranged at the lower end of the robot arm, and can move freely in the direction of the three axes under the drive of the multi-axis robot arm 203.

[0089] The elastic needle 202 is mounted at the bottom of the pressing head 201, and the lower end of the elastic needle 202 is adapted to be elastically supported on the coil 402. The elastic needle 202 has elasticity in the Z-axis direction, and preferably the diameter of the elastic needle 202 is adapted to or slightly smaller than the width of the wire of the coil 402, so that the elastic needle 202 can be pressed on the coil 402 in the Z-axis direction.

[0090] When the winding is completed, the closed magnetic core 401 with the coil 402 is moved to the clamping groove H10 of the loading clamp 10 and clamped. The multi-axis robot arm 203 drives the pressing head 201 to move above the loading clamp 10, ensures that the elastic needle 202 is aligned with the uppermost coil of the coil 402 below, and then the multi-axis robot arm 203 drives the pressing head 201 and the elastic needle 202 to move downward, until the lower end of the elastic needle 202 is elastically supported on the uppermost coil of the coil 402 after the pressing head 201 is lowered to the target height, at this time, the spud 301 is located on one side of the coil 402 and aligned with the uppermost coil, finally, the first driver 302 drives the spud 301 to move in the direction of approaching the coil 402 along the X-axis, and is inserted below the wire end D4b at the upper end of the coil 402, so that the wire end D4b can be easily lifted up.

[0091] In this embodiment, the pressing structure of the elastic needle 202 can ensure that the coil 402 is pressed while the wire end D4b at the upper end of the coil 402 is not pressed, so that the spud 301 can be inserted below the wire end D4b at the upper end of the coil 402, and the wire end D4b can be easily lifted up, and the structure is simple and can ensure the reliability of the lifting of the wire end D4b.

[0092] It should be noted that the elastic needle 202 can be one or more, for example, two elastic needles 202, which are symmetrically arranged on the diameter of the coil 402, and the wire end D4b at the upper end of the coil 402 is located on one side of the two elastic needles 202, so that the coil 402 can be pressed balancedly, and the wire end D4b at the upper end of the coil 402 can be easily offset and lifted up with the insertion of the spud 301.

[0093] Reference Figures 3-7As shown, in one embodiment of the present application, the wire shoveling device 30 further comprises a shoveling seat 303, the shoveling blade 301 is arranged on the shoveling seat 303 and is pivotable between a first position and a second position about a first axis Z01 extending along the Y-axis direction.

[0094] When the shoveling blade 301 is located at the first position, the blade head 301a of the shoveling blade 301 is adapted to be aligned below the wire head D4b inserted into the upper end of the coil 402, and the second position is located above the first position.

[0095] The first driver 302 is connected with the shoveling seat 303 to drive the shoveling seat 303 to move along the X-axis direction.

[0096] That is to say, in the present embodiment, the shoveling blade 301 can rotate up and down relative to the shoveling seat 303 within a certain range, and before the shoveling blade 301 is inserted below the wire head D4b of the upper end of the coil 402, the shoveling blade 301 is kept at the first position, and when the shoveling blade 301 is inserted below the wire head D4b of the upper end of the coil 402, the shoveling blade 301 can float between the first position and the second position. In this way, by adopting such a floating structure design, the size and position errors can be adapted, and it is ensured that the shoveling blade 301 can be smoothly inserted below the wire head D4b of the upper end of the coil 402 even in the presence of certain errors, and the wire head D4b of the upper end of the coil 402 is shoveling up, so that the wire head D4b is offset upward and tilted. Therefore, the size and position accuracy requirements of the shoveling blade 301 are reduced, and the reliability of the wire shoveling device 30 is improved.

[0097] Exemplarily, a pivot slot is arranged at the bottom of the shoveling seat 303, and the shoveling blade 301 is pivotally connected in the pivot slot through a pivot shaft, and the blade head 301a of the shoveling blade 301 extends along the X-axis direction towards the side close to the coil 402. In this way, by the cooperation between the pivot slot and the shoveling blade 301, it can be ensured that the rotation track of the shoveling blade 301 is accurate, stable and reliable when the shoveling blade 301 rotates between the first position and the second position.

[0098] Advantageously, the blade head 301a of the shoveling blade 301 has a flat bottom surface S3a and an inclined top surface S3b, the inclined top surface S3b is located above the flat bottom surface S3a and intersects to form a blade edge adapted to be inserted below the wire head D4b. In this way, when the shoveling blade 301 is inserted below the wire head D4b of the upper end of the coil 402, the wire head D4b is located above the inclined top surface S3b, and under the guidance of the inclined top surface S3b, the wire head D4b is offset upward and tilted. In this way, a better wire head D4b separation effect can be achieved.

[0099] Referring to Figure 3 and Figures 5-7As shown, in some embodiments of the present application, the wire shoveling device 30 is installed at the lower end of the multi-axis robot arm 203 and on one side of the pressing head 201, so as to be synchronously moved by the multi-axis robot arm 203.

[0100] Exemplarily, the pressing head 201 has a horizontally extending plate-shaped portion, the mounting portion of the first driver 302 is installed away from one end of the pressing head 201, and the shovel seat 303 is installed at the bottom of the plate-shaped portion through a slide rail assembly. The first driver 302 can be a linear driver such as a pneumatic cylinder or a linear motor, and when the first driver 302 works, it can drive the shovel seat 303 to slide along the X-axis direction.

[0101] In the present embodiment, the wire shoveling device 30 and the elastic needle 202 are installed on the same multi-axis robot arm 203, and are synchronously moved by the multi-axis robot arm 203, which can simplify the structure of the equipment, and can ensure that the relative position relationship between the shovel 301 and the elastic needle 202 is stable, thereby improving the coordination of the pressing action and the wire shoveling action.

[0102] Referring to Figure 10 and Figure 11 As shown, in some embodiments of the present application, the wire shoveling head mechanism further comprises a wire poking device 50, which is arranged adjacent to the loading clamp 10, and is used to poke the wire end D4a at the lower end of the coil 402 to a predetermined position, so that the wire end D4b at the upper end of the coil 402 is rotated to a position opposite to the shovel 301.

[0103] Since there is a gap between the coil 402 and the side column 4011 of the closed magnetic core 401 after the coil 402 is wound on the side column 4011, the coil 402 can rotate around the axis of the side column 4011, so after winding is completed, the closed magnetic core 401 is transferred to the clamping groove H10 of the loading clamp 10. At this time, the position of the wire end D4a at the lower end of the coil 402 can not be fixed, that is, the wire end D4a of the previous coil 402 and the wire end D4a of the next coil 402 can not be at the same accurate position.

[0104] To this end, in the present embodiment, by configuring the wire poking device 50, after the closed magnetic core 401 is transferred to the clamping groove H10 of the loading clamp 10, the wire end D4a at the lower end of the coil 402 on the closed magnetic core 401 can be poked to a predetermined position by the wire poking device 50. During the process of poking the wire end D4a at the lower end of the coil 402, the coil 402 rotates, and the wire end D4b at the upper end of the coil 402 is rotated to a position opposite the spud 301. In this way, after the elastic needle 202 compresses the coil 402, when the spud 301 moves towards the coil 402, it can be accurately inserted below the wire end D4b at the upper end of the coil 402, forcing the wire end D4b at the upper end of the coil 402 to be upwardly offset and raised. Using this wire poking device 50 to perform the wire poking operation before the elastic needle 202 compresses the coil 402 ensures that the wire end D4b at the upper end of the coil 402 can be accurately positioned opposite the spud 301, and ensures that the wire stripping operation of each coil 402 can be accurately performed, improving the yield rate.

[0105] Referring to Figures 10-11 In one embodiment of the present application, the wire poking mechanism includes a poking member 501, a lifting driving device 502, and a rotating driving device 503.

[0106] The poking member 501 is used to poke the wire end D4a at the lower end of the coil 402. Preferably, the poking member 501 has a poking needle protruding upward, and the diameter of the poking needle is slightly larger than the width of the wire, facilitating the poking of the wire end D4a.

[0107] The lifting driving device 502 is connected to the poking member 501 to drive the poking member 501 to move to the vicinity of the loading clamp 10 and to the outside of the wire end D4a at the lower end of the coil 402.

[0108] The rotating driving device 503 is connected to the poking member 501 to drive the poking member 501 to rotate about a second axis extending in the Z-axis direction, so as to poke the wire end D4a inward to the predetermined position. Exemplarily, the rotating driving device 503 is mounted on the lifting driving device 502, and the poking member 501 is connected to the rotating driving device 503. The lifting driving device 502 can drive the rotating driving device 503 and the poking member 501 to move up and down together, so that the poking member 501 reaches the target height, and the rotating driving device 503 can drive the poking member 501 to rotate to poke the wire.

[0109] Specifically, when the closed magnetic core 401 is moved to the loading clamp 10, the wire end D4a at the lower end of the coil 402 can be first moved outward by driving the pusher 501 upward by the lifting driving device 502, and then moved inward by driving the pusher 501 to rotate by the rotating driving device 503, so that the pusher 501 can move the wire end D4a at the lower end of the coil 402 to a predetermined position, the coil 402 rotates, and the wire end D4b at the upper end of the coil 402 is rotated to a position opposite to the spade 301.

[0110] In the embodiment, the pusher 501 is driven to lift and rotate to complete the wire moving operation, so that the pusher 501 is located below the loading clamp 10 when the wire is not needed to be moved, and does not interfere with the operation of other parts. In addition, the rotating wire moving mode is consistent with the rotating mode of the coil 402, and the wire moving operation is more reliable.

[0111] Referring to Figures 7-9 In one embodiment of the present application, the loading clamp 10 includes a base 101, a movable seat 102, and a second driver 103. A clamping groove H10 is formed on the top of the base 101, and the clamping groove H10 has an open side.

[0112] The movable seat 102 is arranged at the open side and can be switched between an open position and a closed position. Figure 3 In an example, the movable seat 102 is located on one side of the base 101 in the X-axis direction.

[0113] The second driver 103 is connected with the movable seat 102 to drive the movable seat 102 to switch between the open position and the closed position. The second driver 103 includes, but is not limited to, a pneumatic cylinder, a linear motor, etc.

[0114] When the movable seat 102 is in the open position, the movable seat 102 is separated from the base 101 to open the open side. When the movable seat 102 is in the closed position, the movable seat 102 is close to the base 101 to close the open side and clamp the second closed part 4013 of the closed magnetic core 401 in the clamping groove H10.

[0115] In use, the movable seat 102 is kept in the open position, and then the closed magnetic core 401 with the coil 402 is transferred and inserted into the clamping groove H10, then the movable seat 102 is driven by the second driver 103 to move from the open position to the closed position, at this time, the movable seat 102 abuts against the open side of the base 101, so that the clamping groove H10 is closed and the second closed part 4013 of the closed magnetic core 401 in the clamping groove H10 is clamped. The loading clamp 10 with the structure can realize reliable clamping and fixing of the closed magnetic core 401, and can bear a large pressure in the Z-axis direction, and ensure the subsequent operations of the coil pressing device 20 on the coil 402.

[0116] Referring to Figures 5-9 In an embodiment of the present application, the movable seat 102 is pivotally connected with the base 101, and the second driver 103 drives the movable seat 102 to pivot along the third axis Z02 between the open position and the closed position, and the third axis Z02 extends along the Y-axis direction.

[0117] In the embodiment, the movable seat 102 is connected with the base 101 in a pivotally connected manner, and the second driver 103 drives the movable seat 102 to rotate around the third axis Z02, so that the movable seat 102 approaches or moves away from the open side of the base 101, thus realizing the clamping operation, and the structure is simple and the clamping is reliable.

[0118] It can be understood that in other embodiments, the movable seat 102 can also be driven to approach or move away from the open side of the base 101 in a linear driving manner, that is, the movable seat 102 slides linearly relative to the base 101, so that the clamping action can also be realized.

[0119] The wire winding and leg hanging device according to the embodiment of the present application has the wire shoveling head mechanism as described above.

[0120] It can be understood that the wire winding and leg hanging device further includes a wire winding mechanism and a leg hanging mechanism, etc., after the wire winding is completed, the wire end D4b at the upper end of the coil 402 is separated by the wire shoveling head mechanism, and then the upper and lower wire ends D4a and D4b of the coil 402 are clamped and wound on the leg of the skeleton by the leg hanging mechanism.

[0121] According to the winding foot hanging mechanism provided by the embodiment of the present application, after winding is completed, the closed magnetic core 401 with the coil 402 is transferred to the loading clamp 10, clamped by the loading clamp 10, and then the coil 402 is pressed downward along the axial direction by the coil pressing device 20. Finally, the spade 301 is driven by the first driver 302 to move along the X-axis direction to the direction close to the coil 402, and is inserted below the wire end D4b at the upper end of the coil 402. In this way, the wire end D4b at the upper end of the coil 402 can be raised upward. In this way, the wire end D4b at the upper end of the coil 402 can be automatically processed after winding. The processing process is not interrupted by manually drawing the wire end D4b, and the subsequent foot hanging process can be connected to ensure automatic processing, significantly improve the production and processing efficiency, and the length and direction of the automatically formed wire end D4b are consistent, which can ensure that the subsequent foot hanging process is more orderly and smoothly.
