[0105] The functional units in the embodiment and their beneficial effects will be specifically described below.

[0106] Regarding the winding unit 600: it is used to realize the winding process, and after the coil winding process is completed, the wound hollow coil 100 is sleeved on the hexagonal winding mold. The wound hollow coil 100 as a whole is a hexagon matching the shape of the hexagonal winding mold.

[0107] Regarding the flattening unit 700: in order to realize the flattening process, the flattening unit 700 needs to take down the wound hollow coil 100 from the six-sided winding mold and complete the flattening. When taking down the wound hollow coil 100, the six-sided winding mold can be contracted, which is beneficial to the flexible taking down of the wound hollow coil 100. In work, the extending ends of the first and second rubbing plates 111 and 121 respectively hold the two opposite sides (the first and second side walls 101 and 102) of the wound hollow coil 100 outside, and the wound hollow coil 100 is taken out. After the wound hollow coil 100 is taken out, the first and second inner side pressing plates 112 and 122 extend into the wound hollow coil 100, and the first inner side pressing plate 112 cooperates with the extending end of the first rubbing plate 111 to press and clamp the inner and outer sides of the first side wall 101, realizing the fixation of the wire bundle position in the first side wall 101; the second inner side pressing plate 122 cooperates with the extending end of the second rubbing plate 121 to press and clamp the inner and outer sides of the second side wall 102, realizing the fixation of the wire bundle position in the second side wall 102. On this basis, the opening and closing wire head clamping assembly 13 clamps and fixes all the wire heads in the whole flattening process. Finally, the first and second rubbing plates 111 and 121 realize the staggered movement (interleaved movement while approaching each other), and stop the staggered movement when the first and second inner side pressing plates 112 and 122 are about to be attached, realizing the main flattening process of the wound hollow coil (the whole flattening process is composed of the main flattening process and the supplementary flattening process). Then the first and second inner side pressing plates 112 and 122 are drawn out of the wound hollow coil 100 and are spread out, providing space for the continued staggered movement of the first and second rubbing plates 111 and 121. The first and second rubbing plates 111 and 121 continue the staggered movement, realizing the supplementary flattening process of the wound hollow coil, and obtaining the regular wire block 200 in flat shape. The first and second inner side pressing plates 112 and 122 are added in the flattening unit 700, which can ensure that the first and second side walls 101 and 102 are always in the fixed state during the whole main flattening process, and the main flattening process completes most of the deformation action of the whole flattening process, that is, the main flattening process accounts for most of the whole flattening process, which can effectively avoid the slip and dislocation of the wire bundle position during the force flattening process of the wound hollow coil 100, improve the stability of the flattening forming effect, make the obtained regular wire block 200 the same as the predetermined shape, and greatly improve the yield of the regular wire block 200. The added opening and closing wire head clamping assembly 13 can effectively avoid the slip and dislocation of the wire head position during the force flattening process of the wound hollow coil 100, further improving the stability of the flattening forming effect.

[0108] Regarding the material rolling tin immersion shaping unit 800: it can realize the processes of coarse rolling, wire head tin immersion and finishing of the coil, and on the basis of the rolling mold group 0100, the finishing mold group 0200 is added, which can greatly improve the precision of the product.

[0109] Regarding the electrical detection unit 900: in use, the insulation detection rod 03 supports the inside of the finishing round coil 300, which can avoid coil deformation, and the detection probe is used to press the wire end to measure the resistance value, thereby realizing automatic detection of the resistance of the finishing round coil 300.

[0110] As can be seen from the above, the integrated electrical detection function high-precision high-yield hollow cup motor coil production line of the embodiment can improve the stability of the flattening forming effect, increase the rounding device after the coiling, improve the precision of the finishing round coil 300, ensure the product precision and product yield from multiple processes, and realize online detection through the electrical detection unit 900, so that the production line of the present application can directly output qualified products, which can reduce production cost and improve production efficiency, and ultimately improve the overall performance of the present application.

[0111] Please refer to Figures 5-12 , according to the specific embodiment of the present application, the first and second rollers 111 and 121 are oppositely arranged, the first inner side pressing plate 112 is installed on the first roller 111 and moves synchronously with the first roller 111, and the first inner side pressing plate 112 can also independently realize extension and retraction and opening and closing movements, the second inner side pressing plate 122 is installed on the second roller 121 and moves synchronously with the second roller 121, and the second inner side pressing plate 122 can also independently realize extension and retraction and opening and closing movements, the flattening module further comprises an anti-stuck coil flattening dynamic module 2, the anti-stuck coil flattening dynamic module 2 comprises a driving linkage roller 21 and a rotary drive 22; the upper two sides of the driving linkage roller 21 are respectively rotationally connected with the first and second rollers 111 and 121, the rotary drive 22 is connected with the driving linkage roller 21 and coaxial with the driving linkage roller 21, and is used to drive the driving linkage roller 21 to rotate to drive the first and second rollers 111 and 121 to realize the dislocation movement.

[0112] In the embodiment, the rotary drive 22 rotates to drive the driving linkage roller 21 to rotate, thereby realizing the dislocation movement of the first and second rollers 111 and 121. The anti-stuck coil flattening dynamic module 2 discards the existing linear drive dynamic structure (cylinder drive rack structure) and adopts the structure of the rotary drive 22 driving the driving linkage roller 21 to rotate, thereby changing the force transmission mechanism. Since the rotary drive 22 is coaxial with the driving linkage roller 21, in actual application, the driving linkage roller 21 can be driven by the coaxial driving force provided by the rotary drive 22 to ensure the smoothness of the rotation of the driving linkage roller 21, thereby avoiding the situation that the first and second rollers 111 and 121 are subjected to an inclined force from the power source, which is beneficial to ensuring the accuracy of the action of the first and second rollers 111 and 121. Finally, under the joint action of the first and second rollers 111 and 121, the winding of the hollow coil 100 is subjected to a uniform and predetermined direction action flattening force, thereby effectively avoiding the phenomenon of wire bundle dislocation of the winding of the hollow coil 100 during the flattening process, greatly improving the stability of the flattening forming effect and the yield of the regular wire block 200.

The electric detection rotating assembly 01 can be various structures, such as a stepping motor or a structure combined with a stepping motor and a speed reducer. When the electric detection rotating assembly 01 rotates, the insulation detection rod 03 carrying the finishing round coil 300 rotates as a whole to adjust the position of the wire head, so that the wire head finally faces the detection probe. The first detection probe 04 and the second detection probe 05 are respectively connected with the resistance detection equipment, and both the first detection probe 04 and the second detection probe 05 can be telescopic. When the finishing round coil 300 is rotated to the appropriate position, the first wire head 301 faces the first detection probe 04, and the second wire head 302 faces the second detection probe 05. After the first detection probe 04 is extended, it can press the first wire head 301, and after the second detection probe 05 is extended, it can press the second wire head 302. Assuming that the first wire head 301 and the second wire head 302 are two wire heads of the same coil M, in this state, the resistance detection equipment can measure the resistance value of the coil M.

[0214] The working process of the flattening and rounding transfer unit 1000 will be described in detail below.

[0215] First, the regular thread block 200 is located at the flattening station, and the lower part of the regular thread block 200 is clamped by the flattening device. The thread straightening end 00001 is extended to straighten the thread at the top of the regular thread block 200 (for details, refer to the foregoing description). The thread straightening end 00001 is retracted upward above the three-axis transfer module 00004 under the action of the thread straightening lifting drive 0005.

[0216] Then, the clamp lifting drive 0009 is extended downward to drive the clamping end 00002 to move downward to the flattening station and clamp the coil body 304. The flattening device is opened, and the clamping end 00002 is moved to the rounding station under the action of the three-axis transfer module 00004, thereby completing the transfer of the regular thread block 200 from the flattening station to the rounding station. The clamp lifting drive 0009 is retracted upward above the three-axis transfer module 00004.

[0217] The pre-pressing lifting drive 0001 extends downward, the pre-pressing execution end 00003 extends into the rounding station, the rounding station includes a heating and shaping column 000012, the middle section of the sheet-shaped hollow cup coil is tangent to the outside of the heating and shaping column 000012, one end of the regular wire block 200 at the lower part is fixed, and the other end is a free end, under the action of the three-axis transfer module 00004, the clamping execution end 00002 moves and squeezes the free end of the regular wire block 200, and the free end is deformed along the shape of the winding heating and shaping column 000012, the pre-pressing execution end 00003 can complete the pre-deformation before the regular wire block 200 is formally rounded, ensure the smoothness and quality of the subsequent rounding deformation, and is especially suitable for the hollow cup coil which has a relatively large thickness and is difficult to deform once.

[0218] More specifically, the pre-pressing head 0001 includes a mounting block 000101, an upper rotating shaft 000102, and a detachable pre-pressing rod 000103; the mounting block 000101 is fixedly installed at the lower part of the pre-pressing lifting drive 0001, the upper part of the upper rotating shaft 000102 extends into the mounting block 000101, and the upper rotating shaft 000102 is rotatably connected with the mounting block 000101 through a bearing, and the upper part of the detachable pre-pressing rod 000103 is inserted into the upper rotating shaft 000102, and the two are detachably connected.

[0219] In the embodiment, the upper rotating shaft 000102 is rotatably connected with the mounting block 000101 through a bearing, which can ensure the smoothness of the rotation of the upper rotating shaft 000102. The detachable pre-pressing rod 000103 and the upper rotating shaft 000102 are detachably connected, the lower part of the detachable pre-pressing rod 000103 is cylindrical, and in specific implementation, different diameters of the detachable pre-pressing rod 000103 can be installed according to needs to meet the use requirements. The detachable pre-pressing rod 000103 can rotate, and when the sheet-shaped hollow cup coil is pre-pressed, the action mechanism of the detachable pre-pressing rod 000103 is to squeeze the sheet-shaped hollow cup coil while rotating itself, so that the surface of the sheet-shaped hollow cup coil can be prevented from being worn. The quality of the product is further ensured.

[0220] The flattening and rounding transfer unit 1000 integrates the functions of wire straightening, clamping and pre-pressing, compared with conventional coil production devices, the flattening and rounding transfer unit 1000 further has the functions of straightening the flattened wire and pre-deforming before rounding, which greatly improves the forming precision of the product. The flattening and rounding transfer unit 1000 also realizes the transfer of the sheet-shaped hollow cup coil from the flattening station to the rounding station through the clamping execution end 00002, and the three execution ends share one set of three-axis transfer module 00004, which is compact and reasonable in structure and is also conducive to reducing costs.

[0222] The process for producing the hollow cup motor coil by using the application is as follows: winding → twisting and flattening → cutting thread → flattening and shaping → straightening → alcohol immersion → coiling → thread winding → tail cutting → tin immersion → alcohol immersion → rounding → electrical inspection → finished product offline. The device for realizing each process is designed, such as in the process of twisting and flattening, the first inner side pressing plate 112 and the second inner side pressing plate 122 and the opening and closing thread clamping assembly 13 are added, which effectively avoids the slippage and misplacement of the wire bundle and the thread position during the force twisting and flattening process of the wound hollow coil 100, and ensures the twisting and flattening forming effect. The flattening and shaping module is also arranged in the process of twisting and flattening, which further ensures the flattening precision. The thread straightening execution end 00001 in the flattening and rounding transfer unit 1000 is used for straightening the thread, which ensures the position precision of the thread, and the pre-pressing lifting drive 0001 in the flattening and rounding transfer unit 1000 can also cooperate with the coiling module 0100, and can also perform the pre-pressing deformation process before formal coiling, which can improve the coiling success rate and forming precision of the hollow cup coil with large thickness. Moreover, the rounding module 0200 is added on the basis of the coiling module 0100, which can greatly improve the precision of the product.
