Technical Field

[0001] The invention belongs to the technical field of coreless motor coil production, and in particular relates to a coreless motor coil production line with high precision and high yield and integrated electrical inspection function. Background Art

[0002] As one of the core components of the coreless motor, the coreless motor coil plays a decisive role in the overall performance of the motor.

[0004] The shortcomings of the existing technology include the following aspects: (1) When the coil is flattened and formed, the wire harness cannot be fixed, resulting in unstable flattening and forming effects and a high scrap rate. (2) When the sheet coil is rolled up, it is difficult to ensure the production accuracy of the coil by relying solely on the rounding head to round the regular wire block. (3) The electrical inspection process of the coil cannot be completed, and additional electrical inspection equipment must be added or electrical inspection must be performed manually, which is costly. In other words, the alcohol-soluble wire hollow cup armature coil production line system cannot complete the electrical inspection process online, and the hollow cup motor coils produced have technical problems such as low product yield and low precision.

[0005] Therefore, it is necessary to provide a new high-precision and high-yield hollow cup motor coil production line with integrated electrical inspection function to solve the above technical problems. Summary of the Invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0103] The following is combined with Figure 1-31 The present invention will be further described.

[0105] The functional units and their beneficial effects in this embodiment are described in detail below.

[0106] The winding unit 600 is used to implement the winding process. After the coil winding process is completed, the wound hollow coil 100 is placed on the hexagonal winding mold. The wound hollow coil 100 is a hexagonal shape that matches the opened shape of the hexagonal winding mold.

[0107] Regarding the flattening unit 700: This unit is used to perform the flattening process. It removes the wound hollow coil 100 from the hexagonal winding die and flattens it. When removing the wound hollow coil 100, the hexagonal winding die retracts, facilitating flexible removal of the wound hollow coil 100. During operation, the extended ends of the first and second washboards 111, 121 respectively grip the outer sides of the wound hollow coil 100 (the first sidewall 101 and the second sidewall 102) and remove the wound hollow coil 100. After the wound hollow coil 100 is taken out, the first inner pressing plate 112 and the second inner pressing plate 122 are extended into the wound hollow coil 100, and the first inner pressing plate 112 cooperates with the extended end of the first rubbing plate 111 to press and clamp the inner and outer sides of the first side wall 101, thereby fixing the position of the wire harness in the first side wall 101; the second inner pressing plate 122 cooperates with the extended end of the second rubbing plate 121 to press and clamp the inner and outer sides of the second side wall 102, thereby fixing the position of the wire harness in the second side wall 102. On this basis, the opening and closing clamping head assembly 13 is used to clamp and fix all the wire ends during the entire flattening process. Finally, the first rubbing plate 111 and the second rubbing plate 121 are offset (moving in an interlaced manner while approaching each other), until the first inner pressing plate 112 and the second inner pressing plate 122 are about to fit together, and the offset action is stopped, thus completing the main flattening process of winding the hollow coil (the entire flattening process consists of the main flattening process and the supplementary flattening process). Then, the first inner pressing plate 112 and the second inner pressing plate 122 are pulled out from the wound hollow coil 100 and stretched outward, providing space for the first rubbing plate 111 and the second rubbing plate 121 to continue the dislocation action. The first rubbing plate 111 and the second rubbing plate 121 continue the dislocation action to complete the complementary flattening process of the wound hollow coil, and obtain the flat regular wire block 200. The addition of the first inner pressing plate 112 and the second inner pressing plate 122 to the flattening unit 700 can ensure that the first side wall 101 and the second side wall 102 are always in a fixed state throughout the main flattening process, and the main flattening process completes most of the deformation action of the entire flattening process, that is, the main flattening process accounts for the majority of the entire flattening process, which can effectively prevent the wire harness position from slipping and dislocation during the force flattening process of the wound hollow coil 100, improve the stability of the flattening forming effect, and make the obtained regular wire block 200 the same as the predetermined shape, greatly improving the yield rate of the regular wire block 200. Furthermore, the added opening and closing wire clamping head assembly 13 can effectively prevent the wire head from slipping and misaligning during the flattening process of the hollow coil 100, thereby further improving the stability of the flattening forming effect.

[0108] Regarding the coil tinning and shaping unit 800: it can realize the processes of rough coiling, wire end tinning and fine rounding of the coil. On the basis of the coiling module 0100, the whole round module 0200 is added, which can greatly improve the precision of the product.

[0109] Regarding the electrical inspection unit 900: When in use, the insulation inspection rod 03 supports the inner side of the refined circular coil 300 to prevent the coil from deforming. The detection probe is used to press the wire end to measure the resistance value, thereby realizing automatic detection of the resistance of the refined circular coil 300.

[0110] From the above, it can be seen that the high-precision and high-yield hollow cup motor coil production line with integrated electrical inspection function of this embodiment can improve the stability of the flattening forming effect, add a rounding device after rolling, and improve the accuracy of the finished round coil 300, that is, ensure product accuracy and product qualification rate through multiple processes, and realize online inspection through the electrical inspection unit 900, so that the production line of the present invention can directly output qualified products, which can reduce production costs and improve production efficiency, and ultimately improve the overall performance of the present invention.

[0111] Please focus on Figure 5-12 The first and second rubbing plates 111 and 121 are respectively connected to each other in rotation, and the rotation drive 22 is connected to the active linkage rubbing plate 21 and the two are coaxial, and are used to drive the active linkage rubbing plate 21 to rotate to drive the first and second rubbing plates 111 and 121 to achieve staggered movement.

[0112] In this embodiment, the rotary drive 22 rotates, driving the active linkage rubbing plate 21 to rotate, thereby achieving the dislocation movement of the first rubbing plate 111 and the second rubbing plate 121. The anti-jamming coil flattening power module 2 abandons the existing linear drive power structure (cylinder drive rack structure), and adopts a structure in which the rotary drive 22 first drives the active linkage rubbing plate 21 to rotate, thereby changing the force transmission mechanism. Since the rotary drive 22 and the active linkage rubbing plate 21 are coaxial, in actual application, the active linkage rubbing plate 21 can be subjected to the coaxial driving force provided by the rotary drive 22, thereby ensuring the smooth rotation of the active linkage rubbing plate 21, avoiding the first rubbing plate 111 and the second rubbing plate 121 from being subjected to tilting force from the power source, and thus ensuring the accuracy of the movement of the first rubbing plate 111 and the second rubbing plate 121. Finally, under the joint action of the first rubbing plate 111 and the second rubbing plate 121, the wound hollow coil 100 is subjected to a uniform rubbing force that moves in a predetermined direction, effectively avoiding the phenomenon of wire bundle misalignment during the rubbing process of the wound hollow coil 100, and greatly improving the stability of the rubbing forming effect and the yield rate of the regular wire block 200.

[0113] According to a specific embodiment of the present invention, the first rubbing plate 111 includes: a first front and rear rubbing plate 1111 and a first outer pressure plate 1112 fixedly installed at one end of the first front and rear rubbing plate 1111, and the second rubbing plate 121 includes: a second front and rear rubbing plate 1211 and a second outer pressure plate 1212 fixedly installed at one end of the second front and rear rubbing plate 1211; the first inner pressure plate 112 and the first outer pressure plate 1112 are respectively used to press the inner and outer sides of the first side wall 101; the second inner pressure plate 122 and the second outer pressure plate 1212 are respectively used to press the inner and outer sides of the second side wall 102, and the upper two sides of the active linkage rubbing disc 21 are respectively connected to the first front and rear rubbing plates 1111 and the second front and rear rubbing plates 1211 for rotation; the first thread rubbing assembly 11 also includes a means for realizing the independent extension and opening and closing of the first inner pressure plate 112 The first inner pressure plate cross-linear drive 113 moves, and the second thread-rubbing assembly 12 also includes a second inner pressure plate cross-linear drive 123 for realizing the independent extension and extension and opening and closing movement of the second inner pressure plate 122.

[0114] More specifically, both sides of the upper portion of the driven linkage rubbing plate 23 are in sliding contact with the inner side walls of the first front and rear thread rubbing plates 1111 and the inner side walls of the second front and rear thread rubbing plates 1211 respectively.

[0115] In this embodiment, the first inner pressure plate cross linear drive 113 and the second inner pressure plate cross linear drive 123 can be extended and retracted along the length direction of the first rubbing plate 111 and the width direction of the first rubbing plate 111, respectively. The first inner pressure plate cross linear drive 113 and the second inner pressure plate cross linear drive 123 can be existing cross linear drive modules that can be directly purchased from outside, or they can be combined using two linear drive modules. Since the first inner pressure plate 112 is mounted on the first rubbing plate 111, when the first inner pressure plate cross linear drive 113 is stationary, the first inner pressure plate 112 moves synchronously with the first rubbing plate 111; similarly, since the second inner pressure plate 122 is mounted on the second rubbing plate 121, when the second inner pressure plate cross linear drive 123 is stationary, the second inner pressure plate 122 moves synchronously with the second rubbing plate 121.

[0116] More specifically, the first front and rear rubbing plates 1111 are in the shape of horizontal plates. The first outer pressure plate 1112 is in the shape of a slender rod as a whole, and the two are detachably connected. During specific implementation, the first outer pressure plates 1112 of different regular sizes can be replaced according to the specifications of the wound hollow coil 100.

Since the rack 26 is engaged with the driving gear 24 and the driven gear 25 respectively, the driven gear 25 and the driven linkage rubbing plate 23 rotate as a whole. Finally, the first front and rear thread rubbing plate 1111 and the second front and rear thread rubbing plate 1211 are staggered.

[0118] More specifically, the high-precision and high-yield hollow cup motor coil production line with integrated electrical inspection function also includes an operating platform 0700 and a machine cover 500 (such as Figure 1 The winding unit 600, flattening unit 700, coil tinning and shaping unit 800, and electrical inspection unit 900 are each mounted on a work platform 0700.

The gap between the first outer pressure plate 1112 and the second outer pressure plate 1212 is less than or equal to the thickness value of the regular line block 200.

[0120] In the present embodiment, before the supplementary flattening process of winding the hollow coil is performed, the first inner pressure plate cross linear drive 113 drives the first inner pressure plate 112 to be retracted into the first inner pressure plate receiving groove 11111, and at the same time, the second inner pressure plate cross linear drive 123 drives the second inner pressure plate 122 to be retracted into the second inner pressure plate receiving groove 12111, which can reduce the volume of the device and facilitate the first outer pressure plate 1112 and the second outer pressure plate 1212 to continue to close and complete the supplementary flattening process. In the fully retracted state, the setting of the gap between the first outer pressure plate 1112 and the second outer pressure plate 1212 can ensure that the wound hollow coil 100 is completely flattened. In the present embodiment, since the first wire twisting assembly 11 and the second wire twisting assembly 12 are symmetrical structures to each other, the specific structure of the second wire twisting assembly 12 refers to the first wire twisting assembly 11.

[0139] More specifically, the left and right sides of the first adjustment window 1323 each form a complete sheet-shaped holding area; among the multiple wire ends in the wound hollow coil 100, the two wire ends on both sides are set as half-strand wire ends 104 to be twisted together, and the wire end between the two half-strand wire ends 104 to be twisted together is set as a full-strand wire end 105; the full-strand wire end 105 is a complete electrode wire end, and the diameter of the two half-strand wire ends 104 to be twisted together is generally half the diameter of the full-strand wire end 105. In the subsequent process, the two half-strand wire ends 104 to be twisted together need to be twisted together into a full-strand wire end 105.

[0143] During operation, the telescopic cylinder 141 is opened to introduce extension power (for example, if it is a pneumatic cylinder, the air intake chamber is filled with pressurized gas), causing the cylinder rod of the telescopic cylinder 141 to extend and drive the first and second wash plates 111, 121 to open. The closing tension spring 142 is stretched to accumulate elastic force. In this state, the first and second outer pressure plates 1112, 1212 are opened and positioned outside the first and second side walls 101, 102, respectively. When the telescopic cylinder 141 is opened and the extension power is lost, the first and second wash plates 111, 121 are closed under the action of the closing tension spring 142. In this state, the first and second outer pressure plates 1112, 1212 respectively embrace the outside of the first and second side walls 101, 102, and are used to remove the wound hollow coil 100 from the hexagonal winding die.

[0144] Please focus on Figure 18-22 According to a specific embodiment of the present invention, the coil tinning shaping unit 800 includes: a rolling module 0100 for realizing a rough rolling of the regular wire block 200, and a rounding module 0200 for realizing a fine rounding; the rounding module 0200 is arranged on one side of the rolling module 0100; the rounding module 0200 includes: a workbench assembly 0021, a shaping rod 0022, a rotation drive unit 0023, a telescopic drive unit 0024, a left-side pressing die unit 0025 and a right-side pressing die unit 0026; the workbench assembly 0021 includes a support plate 00211, the support plate 00211 is arranged horizontally, the upper part of the shaping rod 0022 passes through the support plate 00211, and the rotation drive unit 0023 is connected to the lower part of the shaping rod 0022 and is used to drive the shaping Rod 0022 rotates; the telescopic drive unit 0024 is connected to the rotation drive unit 0023 and is used to drive the rotation drive unit 0023 and the shaping rod 0022 to rise and fall as a whole; the left die unit 0025 includes: a first telescopic hot press plate assembly, a first telescopic drive 251 connected to the first telescopic hot press plate assembly and used to drive the first telescopic hot press plate assembly to be telescopic; the right die unit 0026 includes: a second telescopic hot press plate assembly, a second telescopic drive 261 connected to the second telescopic hot press plate assembly and used to drive the second telescopic hot press plate assembly to be telescopic; the first telescopic hot press plate assembly and the second telescopic hot press plate assembly are relatively arranged on both sides of the upper part of the shaping rod 0022, and the first telescopic hot press plate assembly and the second telescopic hot press plate assembly together form a pressing cavity.

[0145] In this embodiment, the winding module 0100 is used to round the regular wire block 200 to obtain a coarse round coil 400. The winding module 0100 can adopt the structure of the existing technology. After the regular wire block 200 obtained in the previous process is soaked in alcohol, the regular wire block 200 is beaten into a roughly round shape by the heating and shaping pressing block 000013 in the winding module 0100 to obtain the coarse round coil 400. The wire ends of the coarse round coil 400 are then dipped in tin and then soaked in alcohol. The coarse round coil 400 is then finely rounded using the rounding module 0200 to obtain the fine round coil 300.

[0146] The first telescopic drive 251 and the second telescopic drive 261 can be air cylinders or oil cylinders for providing linear telescopic power. The rotation drive unit 0023 can be a rotary motor or a rotary cylinder for providing rotational power.

[0147] The specific process of rounding is as follows: the second manipulator 0600 grasps the coarse round coil 400 and places it over the shaping rod 0022, with the thread end of the coarse round coil 400 facing upward. The support plate 00211 supports the coarse round coil 400. Under the action of the first and second telescopic drives 251 and 261, the first and second telescopic hot press assemblies simultaneously extend and directly apply pressure to the outside of the coarse round coil 400, adjusting its shape. Under the action of the first and second telescopic drives 251 and 261, the first and second telescopic hot press assemblies simultaneously retract. The rotation drive unit 0023 rotates the shaping rod 0022 to a certain angle and then stops. The first and second telescopic hot press assemblies simultaneously extend and retract again, directly applying pressure to the outside of the coarse round coil 400. After repeated steps, the rounding process is completed, and a round coil 300 with a relatively high roundness is obtained. In this state, the round coil 300 is wrapped around the shaping rod 0022. The telescopic drive unit 0024 descends, driving the rotary drive unit 0023 and the shaping rod 0022 to descend as a whole, removing the round coil 300 from the shaping rod 0022. After the round coil 300 is removed, the shaping rod 0022 is re-extended, preparing for the finishing process of the next rough round coil 400.

[0148] In this embodiment, the pressing cavity matches the shape of the outer side of the hollow cup motor coil. Therefore, when the first telescopic hot pressing plate assembly and the second telescopic hot pressing plate assembly act on the outer side of the coarse round coil 400 at the same time, the shaping accuracy can be greatly improved. By rotating the angle of the shaping rod 0022 multiple times and performing a hot pressing shaping on the outer side of the coarse round coil 400 after each rotation, the accuracy of the finished round coil 300 is greatly improved. The telescopic drive unit 0024 descends to separate the shaping rod 0022 and the finished round coil 300 wrapped around the shaping rod 0022, thereby realizing material withdrawal. This facilitates the flexible transfer of the finished round coil 300 to the next process, and the direction of material withdrawal is downward along the axis of the finished round coil 300. With this structure, there is enough space to arrange the telescopic drive unit 0024 without destroying the shape of the finished round coil 300.

[0149] According to a specific embodiment of the present invention, the press-fitting cavity is a complete cylindrical shape, and a buffer spring 0029 is provided between the first and second telescopic hot-pressing plate assemblies. The full-circular module 0200 also includes a limiting flange 0030, which is removably mounted on the support plate 00211. The upper portion of the shaping rod 0022 also passes through the limiting flange 0030, and the shaping rod 0022 is slidably connected to the limiting flange 0030. An annular support step 00301 is provided on the upper portion of the limiting flange 0030. In this embodiment, when the first and second telescopic hot-pressing plate assemblies are aligned, they perfectly enclose the press-fitting cavity. With the buffer spring 0029 in place, the closer the first and second telescopic hot-pressing plate assemblies are, the greater the spring force they experience, ultimately ensuring a smooth alignment of the first and second telescopic hot-pressing plate assemblies and preventing impact. The stop flange 0030 is removably mounted on the support plate 00211. During implementation, the height of the annular support step 00301 of the stop flange 0030 can be adjusted appropriately based on the height of the coreless motor coil, ensuring that the first and second telescopic hot platen assemblies precisely press against the outer surface of the coreless motor coil when extended. The annular support step 00301 supports the bottom of the coreless motor coil. The left die unit 0025 and the right die unit 0026 are symmetrical structures.

[0151] In this embodiment, the first and second retractable hot press plate assemblies are symmetrically constructed, reducing the number of parts and lowering costs. The first shaping mold 255 is embedded in the first module receiving slot 2541. The first shaping mold 255 is interchangeable, allowing for flexible replacement of different first shaping molds 255 to achieve the desired pressing cavity shape, depending on the size of the coreless motor coil. The first electric heating tube 256 heats the first heating plate 254. The first thermocouple 257 detects the temperature of the first heating plate 254 and, in conjunction with the control circuit, controls the temperature of the first heating plate 254, ultimately achieving hot pressing and shaping of the thick round coil 400 within a preset temperature range. The first mounting plate 252 serves as a mounting base for the first insulating graphite plate 253 and the first heating plate 254 and also connects the first retractable drive 251 to the first mounting plate 252. The structure and function of the second retractable hot press plate assembly refer to the above description of the first retractable hot press plate assembly.

[0152] According to a specific embodiment of the present invention, the first telescopic drive 251 is a pneumatic cylinder or an oil cylinder; the second telescopic drive 261 is a cylinder or an oil cylinder; the full circle module 0200 further includes a spring positioning rod 0027, and the workbench assembly 0021 further includes a first vertical mounting plate 212 and a second vertical mounting plate 213 relatively arranged on both sides of the support plate 00211; one end of the spring positioning rod 0027 passes through the first mounting plate 252 and is fixed to the first vertical mounting plate 212, and the other end of the spring positioning rod 0027 passes through the second mounting plate 262 and is fixed to the first vertical mounting plate 212. The second vertical mounting plate 213 is fixed; the first mounting plate 252 and the second mounting plate 262 are respectively slidably connected to the spring positioning rod 0027, the buffer spring 0029 is sleeved on the spring positioning rod 0027, and the two ends of the buffer spring 0029 are respectively abutted against the first mounting plate 252 and the second mounting plate 262; the first telescopic drive 251 is installed on the side of the first vertical mounting plate 212 away from the second vertical mounting plate 213, and the second telescopic drive 261 is installed on the side of the second vertical mounting plate 213 away from the first vertical mounting plate 212.

[0153] In this embodiment, the spring positioning rod 0027 can limit the position of the buffer spring 0029, ensuring the stability of its telescopic movement. During use, the first telescopic driver 251 drives the first mounting plate 252 to slide along the spring positioning rod 0027, and the first mounting plate 252 compresses one end of the buffer spring 0029. Simultaneously, the second telescopic driver 261 drives the second mounting plate 262 to slide along the spring positioning rod 0027, and the second mounting plate 262 compresses the other end of the buffer spring 0029.

[0154] According to a specific embodiment of the present invention, the first mounting plate 252 and the second mounting plate 262 are both rectangular, the number of spring positioning rods 0027 is four, and the four spring positioning rods 0027 are respectively located at the four corners of the first mounting plate 252, and each spring positioning rod 0027 is provided with a buffer spring 0029, and the first thermal insulation graphite plate 253, the first heating plate 254, the second thermal insulation graphite plate 263 and the second heating plate 264 are all located in the space surrounded by the four spring positioning rods 0027.

[0155] In this embodiment, four buffer springs 0029 are arranged at the corners of the first mounting plate 252 and the second mounting plate 262, and the four buffer springs 0029 are arranged around the first heating plate 254 and the second heating plate 264, which is conducive to providing uniform buffering force and ensuring the smooth extension and retraction of the first telescopic hot pressure plate assembly and the second telescopic hot pressure plate assembly.

[0156] According to a specific embodiment of the present invention, the workbench assembly 0021 also includes: an inner support frame 214 arranged below the support plate 00211, and an outer support frame 215 arranged around the inner support frame 214. The inner support frame 214 and the outer support frame 215 are both rectangular frames with an upper opening as a whole. A set of slide rails 0028 are respectively provided between the two outer side walls of the inner support frame 214 and the two inner side walls of the outer support frame 215 to realize the sliding connection between the inner support frame 214 and the outer support frame 215; the rotation drive unit 0023 includes a rotating motor body and a motor shaft. The motor body is installed at the lower part of the inner support frame 214, and the motor shaft is connected to the shaping rod 0022 via a coupling 39; the telescopic drive unit 0024 includes a telescopic cylinder body 241 and a cylinder telescopic rod 242. The telescopic cylinder body 241 is installed at the lower part of the outer support frame 215, and the cylinder telescopic rod 242 is fixed to the lower part of the inner support frame 214.

[0157] In this embodiment, the inner support frame 214 is a rectangular frame with an open top, while the outer support frame 215 is a rectangular frame with an open top formed by offsetting the inner frame outward. This structure creates a gap between the sidewalls of the inner and outer support frames 214, 215, allowing for symmetrical installation of the slide rails 0028, ensuring smooth sliding between the inner and outer support frames 214, 215. The gap between the sidewalls of the inner and outer support frames 214, 215 provides space for the telescopic drive unit 0024 to extend and retract. During operation, the motor shaft rotates, driving the shaping rod 0022 through the coupling 39 to adjust the rotation angle of the finishing circular coil 300 during the finishing process. The cylinder telescopic rod 242 extends and retracts, driving the inner support frame 214 and all components mounted thereon, including the shaping rod 0022, to facilitate the removal of the finished circular coil 300 after inspection.

[0158] According to a specific embodiment of the present invention, the insulated wire is an enameled wire, which has the advantages of being soft and easy to bend and shape, and can also be replaced by a self-adhesive enameled wire.

[0159] According to a specific embodiment of the present invention, coil tinning and shaping unit 800 further includes a tinning device 0300 located on one side of coiling module 0100. Tinning device 0300 comprises a tin pot 0031, a push plate 0032 positioned above tin pot 0031, and a tinning and retracting power drive 0033 for driving push plate 0032 to extend and retract. Tinning and retracting power drive 0033 and push plate 0032 are fixedly connected via a heat shield 0034. More specifically, tin pot 0031 is made of titanium alloy to prevent tin from sticking.

[0160] In this embodiment, the tinning telescopic drive 0033 is used to provide telescopic power. It can be a pneumatic or electric telescopic cylinder. Before tinning the wire ends of the coreless motor, the tinning telescopic drive 0033 is used to drive the push plate 0032 to extend and retract, thereby removing the oxide layer on the surface of the tin liquid in the tin pot 0031 and ensuring the quality of the tinning of the wire ends.

[0161] According to a specific embodiment of the present invention, the coil tin dipping and shaping unit 800 also includes: a first alcohol tank 0900, a second alcohol tank 0500, a first manipulator 0800, a second manipulator 0600 and a turntable 0400; the full circle module 0200, the tin dipping device 0300 and the turntable 0400 are all located on the same side of the coiling module 0100, the first alcohol tank 0900 is located on the other side of the coiling module 0100, the second alcohol tank 0500 is arranged between the full circle module 0200 and the tin dipping device 0300, the turntable 0400 is located between the full circle module 0200 and the tin dipping device 0300, and the second alcohol tank 0500 is located on the side of the turntable 0400 away from the coiling module 0100.

[0162] More specifically, the area where the first alcohol tank 0900, the rolling module 0100, the tin pot 0031, and the side of the turntable 0400 close to the tin pot 0031 are located is set as the first area; the area where the side of the turntable 0400 close to the full circle module 0200, the second alcohol tank 0500, and the full circle module 0200 are located is set as the second area; the first manipulator 0800 is used to realize the change of the position of the hollow cup motor coil in the first area; the second manipulator 0600 is used to realize the change of the position of the hollow cup motor coil in the second area.

[0163] The working principle of the coil tin dipping and shaping unit 800: first, use the first robot 0800 to grab the regular wire block 200 and complete the alcohol dipping process before rough rolling in the first alcohol tank 0900, so as to achieve the effect of removing impurities, enhancing softness and improving the bonding performance of the coil after rolling; then the first robot 0800 grabs the regular wire block 200 and moves it to the winding module 0100 to complete the rough rolling process, and then the first robot 0800 grabs the rough rolled coil 400 and rotates it 180°, so that the wire end is immersed in the tin pot 0031 to complete the tin dipping process, and then the coil after tinning is transferred to the turntable 0400 close to the tin pot 0031. The turntable 0400 is used to support the coarsely wound coil 400 after tinning, so that the second manipulator 0600 can grab it. The second manipulator 0600 grabs the coarsely wound coil 400 and completes the alcohol soaking process before finishing the round in the second alcohol tank 0500, so as to remove impurities, enhance flexibility, and improve the bonding performance of the coil after finishing the round. Then, the second manipulator 0600 grabs the coarsely wound coil 400 after alcohol soaking and moves it to the round module 0200 to complete the round finishing process and obtain the finished round coil 300. In this embodiment, by rationally arranging the positions of the various components, the occupied volume of the device can be reduced. By utilizing the structure of this embodiment, the processes of single alcohol soaking, coarse rolling, tinning, secondary alcohol soaking and round finishing can be realized, which greatly improves the quality of the hollow cup motor coil.

[0164] According to a specific embodiment of the present invention, turntable 0400 includes a support frame 41, a table rotating power unit 42 mounted on top of the support frame 41, and a rotating plate 43 mounted on top of the table rotating power unit 42 and driven for rotation by the table rotating power unit 42. A raised support column 44 is provided on either side of the top of the rotating plate 43. More specifically, the outer diameter of the support column 44 matches the inner diameter of the coreless motor coil. More specifically, the table rotating power unit 42 can be a rotary motor or a rotary cylinder.

[0165] In this embodiment, the support columns 44 on the turntable 0400 are used to support the coreless motor coils. During use, the first manipulator 0800 moves the coreless motor coils to the support columns 44 on the side of the tin pot 0031. With this structure, the turntable 42 rotates, transferring the coreless motor coils from the side of the tin pot 0031 to the side of the full-circle module 0200. The beneficial effects of this structure include: on the one hand, it reduces the travel range of the second manipulator 0600, further reducing the size of the device. On the other hand, after the support columns 44 are provided, while the second manipulator 0600 grabs the coreless motor coils on the side of the full-circle module 0200, the first manipulator 0800 can simultaneously place the tinned coreless motor coils on the support columns 44 on the side of the tin pot 0031. This avoids waiting, ensures the continuity of the tinning and alcohol dipping processes, and ensures production efficiency.

[0166] According to a specific embodiment of the present invention, the rolling module 0100 includes: an automatic wire cutting clamp 000011, a heating and shaping column 000012, a coarse rolling linear drive 000014, and a plurality of heating and shaping blocks 000013 arranged around the outside of the heating and shaping column 000012; each heating and shaping block 000013 is connected by a coarse rolling linear drive 000014, a thermocouple is provided in the heating and shaping column 000012, and a thermocouple is provided in the heating and shaping block 000013. A wire collecting groove 15 is also provided on one side of the rolling module 0100; the coil tinning shaping unit 800 also includes an operating platform 0700, and the rolling module 0100, the whole circle module 0200, the tinning device 0300, the turntable 0400, the first alcohol tank 0900, the first manipulator 0800, the second alcohol tank 0500 and the second manipulator 0600 are all installed on the operating platform 0700.

[0167] In this embodiment, the rough coiling linear drive 000014 expands and contracts, driving the heating and shaping block 000013 to expand and contract, thereby rounding the regular wire block 200 placed against the heating and shaping column 000012, thus completing the rough coiling process. In this embodiment, thermocouples are installed in both the heating and shaping column 000012 and the heating and shaping block 000013 to increase the speed and uniformity of the heating of the regular wire block 200, thereby improving the quality of the coil winding.

[0168] According to a specific embodiment of the present invention, a wire winding module is also provided above the winding module 0100 for winding two half-strand wire ends into one. The automatic wire trimmer 000011 is used to trim the tail of the wound wire ends, and the discarded wire ends are collected by the wire collection trough 15. More specifically, the coil tinning shaping unit 800 also includes an operating platform 0700, on which the winding module 0100, the rounding module 0200, the tinning device 0300, the turntable 0400, the first alcohol tank 0900, the first manipulator 0800, the second alcohol tank 0500, and the second manipulator 0600 are all installed.

[0169] In this embodiment, the various functional components are integrated through the operating platform 0700 to improve the integrity of the present invention.

[0170] In summary, the coil tin dipping and shaping unit 800 of the present invention has the following beneficial effects: (1) Product precision: On the basis of the coarse rolling device, a full circle module 0200 is also provided, and the coarse rolled coil 400 is hot pressed at different angles using the inner wall of the pressing cavity that matches the outer shape of the hollow cup motor coil, which greatly improves the precision of the product; an alcohol dipping device is provided on one side of each set of rolling devices, which can further improve the precision of product processing. (2) Production efficiency: The first manipulator 0800, the second manipulator 0600 and the turntable 0400 cooperate to realize the transfer of the hollow cup motor coil between various workstations, and the provision of the turntable 0400 can also ensure the continuous movement of the first manipulator 0800 and the second manipulator 0600, thereby improving production efficiency. (3) Overall performance: The various functional parts are integrated on the workbench and reasonably arranged, so that the overall structure of the present invention is compact and small in size.

[0171] Please focus on Figure 23-31 According to a specific embodiment of the present invention, the coil body 304 is annular in shape as a whole; the electric inspection unit 900 further includes: an openable and closable clamp 02 located outside the insulation inspection rod 03 and used to clamp and fix the coil body 304, an electric inspection rotating assembly 01 fixedly connected to the lower part of the insulation inspection rod 03 and used to drive the insulation inspection rod 03 to rotate; a plane passing through the first wire end 301 and the rotation axis of the coil body 304 is P1 (such as Figure 24 ), the plane passing through the second wire end 302 and the rotation axis of the coil body 304 is P2; the angle between P1 and P2 is K; the angle between the first detection probe 04 and the second detection probe 05 is also K.

[0172] In this embodiment, the insulation test rod 03 is made of an insulating material and is used to support the finished circular coil 300. The outer diameter of the portion of the insulation test rod 03 that contacts the coil body 304 (the lower section of the insulation test rod 03) matches the inner diameter of the coil body 304. When the retractable clamp 02 is closed, the insulation test rod 03 provides a contact base for the retractable clamp 02, preventing the retractable clamp 02 from flattening the coil body 304. In addition, the upper section of the insulation test rod 03 provides an abutment base for the detection probe, ensuring that when the detection probe is extended and presses against the wire end, the detection probe and the wire end are effectively electrically connected, facilitating accurate resistance measurement.

[0173] The retractable clamp 02 can be opened and closed. When closed, it acts on the two opposing outer sides of the coil body 304, clamping the coil body 304 to the insulation test rod 03 and ensuring synchronous rotation of the coil body 304 and the insulation test rod 03. When the retractable clamp 02 is opened, the finished round coil 300 can be freely removed. The retractable clamp 02 can have various structures, such as a conventional two-finger pneumatic clamp or a centering clamping structure with a motor-driven forward and reverse screws that rotate the left and right jaws to synchronize the opening and closing of the left and right jaws.

[0174] The electric inspection rotating assembly 01 is used to provide rotational power to adjust the angle of the finishing circular coil 300 mounted on the insulation detection rod 03. The electric inspection rotating assembly 01 is used to automatically rotate the motor coil to a position where the wire end is aligned with the detection probe, thereby improving the detection efficiency and accuracy. The electric inspection rotating assembly 01 can be a variety of structures, such as a stepper motor or a combination of a stepper motor and a reducer. When the electric inspection rotating assembly 01 rotates, the insulation detection rod 03 carries the finishing circular coil 300 and rotates as a whole to adjust the position of the wire end, and finally sets the wire end directly opposite the detection probe. The first detection probe 04 and the second detection probe 05 are respectively connected to the resistance detection equipment, and the first detection probe 04 and the second detection probe 05 are both retractable. When the finishing circular coil 300 is rotated to the appropriate position, the first wire head 301 is set opposite the first detection probe 04, and the second wire head 302 is set opposite the second detection probe 05. After the first detection probe 04 is extended, it can just press the first wire head 301, and after the second detection probe 05 is extended, it can just 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 section of coil M, in this state, the resistance detection equipment can measure the resistance value of the coil M. If the resistance value is within the design range, it means that the coil M is in a qualified state. It should be noted that the first wire head 301 and the second wire head 302 can also be wire heads of different sections of coils. Comparing the measured resistance value with the designed resistance value can also be used as a basis for determining whether the finishing circular coil 300 is qualified.

[0175] There are many structures for realizing the extension and retraction of the first detection probe 04 and the second detection probe 05. For example, the detection probes can be installed on the telescopic cylinder 0141, and the telescopic cylinder 0141 provides the telescopic power, or the detection probes can be used as the top rod of the cam, and the telescopic cylinder 0141 provides the telescopic power.

[0176] The following describes in detail the use of the electrical inspection unit 900 of this embodiment.

[0177] First, open the retractable clamp 02. Then, place the finished circular coil 300 on the insulation test rod 03, ensuring that the wire end faces upward. Then close the retractable clamp 02, clamping the finished circular coil 300 onto the insulation test rod 03. The electrical inspection rotation assembly 01 rotates the insulation test rod 03, the retractable clamp 02, and the finished circular coil 300 as a whole, stopping when the wire end faces the inspection probe. The inspection probe extends and presses the wire end, connecting the resistance inspection channel. The resistance inspection device connected to the inspection probe can measure and display the resistance value, completing the resistance inspection of the finished circular coil 300.

[0178] Compared to existing technologies, the electrical testing unit 900 of the present invention uses an insulation test rod 03 to support the inner side of the finished circular coil 300, preventing deformation of the finished circular coil 300 during testing. The electrical testing rotation assembly 01 automatically rotates the finished circular coil 300 until the end of the coil aligns with the test probe, which then presses against the end of the coil to measure the resistance.

[0188] In this embodiment, the electric inspection clamping platform 021 is fixedly mounted on the clamping platform support ring 153 of the electric inspection rotating sleeve 015, so that the openable and closable clamp 02 as a whole can rotate synchronously with the electric inspection rotating sleeve 015. The openable and closable clamp 02 is a normally closed structure, which can be realized by using a compression spring or a compression airbag. Under the action of the compression spring or the compression airbag, the jaws of the first clamping unit 023 and the second clamping unit 024 are pressed to achieve normal closure. The jaw opening drive unit 0014 is used to drive the first clamping unit 023 and the second clamping unit 024 to open.

The first rotating wheel 234 rotates under the pressure of the first inclined surface 1421 and drives the first pressing claw 233 to open. The first pressing claw 233 directly acts on the motor coil. Under normal conditions, the first compression spring 237 compresses the first L-shaped pressure block 232, enabling the first pressing claw 233 to act on the motor coil. The shape of the first pressure groove 2331 matches the outer shape of the motor coil to ensure sufficient clamping contact surface. Since the second clamping unit 024 and the first clamping unit 023 are symmetrical structures, the structure and function of the second clamping unit 024 refer to the above description of the first clamping unit 023 .

[0194] In this embodiment, hollow mounting hole 1423 serves two purposes: first, it facilitates screw insertion, connecting triangular plate 0142 to telescopic cylinder 0141; second, the hollow structure facilitates weight reduction. Angle adjustment mounting slot 061 serves as a screw mounting hole for mounting the first telescopic sliding assembly 07 or the second telescopic sliding assembly 08. With the arc-shaped angle adjustment mounting slot 061, the first and second telescopic sliding assemblies 07 and 08 can freely select their installation positions along the extension direction of angle adjustment mounting slot 061, ensuring that the angle between the first and second telescopic sliding assemblies 07 and 08 matches the thread ends of different motor coil models.

[0195] According to a specific embodiment of the present invention, the first electric inspection head telescopic sliding assembly 07 includes: a first cylinder mounting seat 71, a first slide cylinder 72, a first mounting angle block 73 and a first mounting sliding block 74; the first mounting angle block 73 includes a first horizontal mounting plate 731 and a first vertical mounting plate 732 fixedly connected at the ends, the first horizontal mounting plate 731 is installed on the top of the first slide cylinder 72, the first vertical mounting plate 212 is provided with a recessed first vertical adjustable mounting groove 7321 on one side close to the insulation detection rod 03, the side of the first vertical mounting plate 732 is provided with a first lateral locking hole 7322 connected to the first vertical adjustable mounting groove 7321, the number of the first lateral locking holes 7322 is multiple, and the multiple first lateral locking holes 73 22 are arranged at intervals along the extension direction of the first vertical adjustable mounting slot 7321; one side of the first mounting slide block 74 is inserted into the first vertical adjustable mounting slot 7321, and at least one first lateral locking hole 7322 is provided with a first lateral locking screw for locking and fixing the first mounting slide block 74; the other side of the first mounting slide block 74 is provided with a recessed stylus fixing hole, and one end of the first detection probe 04 is inserted into and fixed in the stylus fixing hole; the bottom of the slide cylinder is connected to the detection platform mounting plate 06 through the first cylinder mounting seat 71; the bottom of the first cylinder mounting seat 71 is installed on the upper part of the angle adjustment mounting slot 061 through a threaded connection; the structure of the second electrical inspection head telescopic sliding assembly 08 and the first electrical inspection head telescopic sliding assembly 07 are the same.

A wire cutting head module is also provided between the flattening module and the flattening shaping module. The high-precision and high-yield hollow cup motor coil production line with integrated electrical inspection function also includes a flattening full circle transfer unit 1000 provided behind the flattening shaping module. The flattening full circle transfer unit 1000 includes a wire end straightening execution terminal 00001, a wire end straightening The straight execution end 00001 includes a second two-finger opening and closing clamp 0001 and two sets of wire-straightening execution parts 0002 respectively connected to the second two-finger opening and closing clamp 0001. The wire-straightening execution part 0002 includes: a wire-straightening clamp 00021, a wire-straightening quick-change clamp 00022 and a tooth gap adjustment telescopic drive 00023; the lower part of the wire-straightening clamp 00021 is provided with a recessed mounting groove 211, and the length and width directions of the mounting groove 211 are respectively in the X direction and the Y direction; the two sets of wire-straightening execution parts 0002 include: a wire-straightening clamp 00021, a wire-straightening quick-change clamp 00022 and a tooth gap adjustment telescopic drive 00023; the lower part of the wire-straightening clamp 00021 is provided with a recessed mounting groove 211, and the length and width directions of the mounting groove 211 are respectively in the X direction and the Y direction; The two-finger opening and closing jaws 0001 are arranged opposite to each other along the X direction, and the second two-finger opening and closing jaws 0001 are used to drive the two sets of wire-winding actuators 0002 to open and close along the X direction; the upper part of the wire-winding quick-change jaws 00022 extends into the installation slot 211, and the tooth gap adjustment telescopic drive 00023 is installed on one side of the wire-winding jaws 00021. The tooth gap adjustment telescopic drive 00023 is connected to the wire-winding quick-change jaws 00022 and is used to drive the wire-winding quick-change jaws 00022 to move along the Y direction. The two sets of wire-winding actuators 000 The lower parts of the two wire straightening quick-change clamps 00022 in 2 are respectively fixedly connected with the first wire straightening quick-change comb teeth 0003 and the second wire straightening quick-change comb teeth 0004; the wire straightening execution terminal 00001 also includes a wire straightening lifting drive 0005 fixed to the upper part of the second two-finger opening and closing clamp 0001, and the height direction of the mounting groove 211 is set as the Z direction. The wire straightening lifting drive 0005 is used to drive the second two-finger opening and closing clamp 0001 and the wire straightening execution part 0002 to rise and fall as a whole along the Z direction.

[0200] More specifically, the cutting head module includes a die cutting edge and a punch cutting edge, which are slidably connected and together form a cutting edge. The cutting head module is used to shear off the non-end thread ends (the aforementioned full-strand thread ends 105) after the thread is twisted and flattened. The excess part of the full-strand thread ends 105 is removed, and the two half-strand thread ends at the ends need to be wound into one in the subsequent process before the thread ends are cut. The flattening and shaping module includes two openable and closable pressure blocks. When closed, the thread blocks after twisting and flattening are flattened and shaped.

[0201] It should be noted that the flattened full-circle transfer unit 1000 can replace the aforementioned first robot 0800.

[0202] In this embodiment, the second two-finger opening and closing jaw 0001 opens and closes, driving the two sets of wire-straightening actuators 0002 to open and close, and the first wire-straightening quick-change comb teeth 0003 and the second wire-straightening quick-change comb teeth 0004 open and close synchronously. The first wire-straightening quick-change comb teeth 0003 and the second wire-straightening quick-change comb teeth 0004 both have a tooth-like structure, and the two can move closer to or farther away from each other under the action of two tooth gap adjustment telescopic drives 00023. And the gap of the tooth-like structure is set according to the gap between the roots of the thread ends on the rule line block 200, to ensure that the first wire-straightening quick-change comb teeth 0003 and the second wire-straightening quick-change comb teeth 0004 can cooperate to straighten the thread ends directly above each other. The wire-straightening lifting drive 0005 is provided on the upper part of the second two-finger opening and closing jaw 0001, which is conducive to lifting and lowering.

[0203] When the thread cutting head module performs the thread cutting process or the flattening or squeezing shaping process, resulting in an inaccurate position of the thread end, the thread end straightening execution terminal 00001 can be used to straighten the thread end before entering the next process. The use process of the thread end straightening execution terminal 00001 is as follows: the flattening or squeezing shaping device clamps the coil body 304 with the thread end facing upward, and the thread end straightening execution terminal 00001 of the present invention is moved above the thread end. The second two-finger opening and closing clamp 0001 drives the first thread straightening quick-change comb 0003 and the second thread straightening quick-change comb 0004 to open along the X direction, aligning the thread ends and moving them downward, and ensuring that each thread end is located within the gap between the teeth of the first thread straightening quick-change comb 0003 and the second thread straightening quick-change comb 0004. Under the action of the two tooth gap adjustment telescopic drives 00023, the first and second quick-change comb teeth 0003 and 0004 move closer together, reducing the gap between the teeth until it is slightly larger than or equal to the maximum horizontal dimension of the thread. The second two-finger opening and closing jaws 0001 and the two sets of thread straightening actuators 0002 then move upward as a whole, and the thread is straightened by the first and second quick-change comb teeth 0003 and 0004. The thread straightening actuator terminal 00001 can straighten multiple deformed threads simultaneously, improving product precision. After the threads are straightened, they are easier to precisely position, reducing the difficulty of automating subsequent processes.

[0204] More specifically, a plurality of first racks 00031 are provided on the side of the first thread-straightening quick-change comb tooth 0003 close to the second thread-straightening quick-change comb tooth 0004, and a plurality of second racks 00041 are provided on the side of the second thread-straightening quick-change comb tooth 0004 close to the first thread-straightening quick-change comb tooth 0003. The first racks 00031 and the second racks 00041 are staggered; the two tooth gap adjustment telescopic drives 00023 in the two sets of thread-straightening actuators 0002 are located on the same side of the second two-finger opening and closing clamp 0001.

[0205] In this embodiment, when the second two-finger opening and closing jaw 0001 is closed, the first rack 00031 and the second rack 00041 are staggered and inserted into each other. A first rack 00031 and a second rack 00041 connected to it together form a thread straightening space, and a thread straightening space encloses a thread. The two tooth gap adjustment telescopic drives 00023 located on the same side, one extending and the other retracting, can shorten the gap between the first rack 00031 and the adjacent second rack 00041 until the required gap for thread straightening is achieved and then stop. The two tooth gap adjustment telescopic drives 00023 are located on the same side, which can reduce the space occupied and make the structure more compact.

[0207] In this embodiment, the provision of a sliding guide 0006 facilitates smoother Y-axis movement of the thread-straightening quick-change jaw 00022. One end of the guide post 00062 can be tightened within the side wall of the thread-straightening jaw 00021, or secured with a pin, to prevent axial slippage during use. To remove the guide post, the guide post 00062 can be knocked out in the opposite direction, ensuring quick installation and replacement of the thread-straightening quick-change jaw 00022.

[0208] More specifically, a set of sliding guides 0006 are located above and below the connection between the backlash adjustment telescopic drive 00023 and the thread-straightening quick-change clamp 00022. In this embodiment, this structure, with a set of sliding guides 0006 located above and below the power element, provides better guidance balance and further helps ensure smooth sliding of the thread-straightening quick-change clamp 00022.

[0209] More specifically, the wire drawing actuator 0002 also includes two Y-direction limit screws 0007 respectively provided on both sides of the wire drawing quick-change clamp 00022, one end of the Y-direction limit screw 0007 is threadedly connected to the wire drawing clamp 00021, and the other end extends into the mounting groove 211, and is used to limit the movement of the wire drawing quick-change clamp 00022 along the Y-direction; the Y-direction limit screw 0007 is located below the sliding guide 0006. It should be noted that, in specific implementation, the electrical system can be combined to realize the control of the movement stroke of the wire drawing quick-change clamp 00022. In this embodiment, the use of the Y-direction limit screw 0007 can ensure that in the event of failure of the electrical system, a mechanical limit method is adopted to ensure that the wire drawing quick-change clamp 00022 slides within a predetermined stroke, thereby avoiding over-travel movement and the phenomenon of the first rack 00031 and the second rack 00041 colliding with the teeth.

[0210] The first quick-change comb teeth 0003 and the quick-change clamping jaw 00022 are detachably connected via a threaded connection, the second quick-change comb teeth 0004 and the quick-change clamping jaw 00022 are detachably connected via a threaded connection, and the quick-change clamping jaw 00022 is detachably connected to the clamping jaw 00021. It should be noted that the tooth pitch of the first quick-change comb teeth 0003 and the second quick-change comb teeth 0004 must match the spacing between the wire ends of the sheet coil to be straightened. When the specifications of the hollow cup motor coil to be produced are different, the distance between the wire ends may also be different, and the first quick-change comb teeth 0003 and the second quick-change comb teeth 0004 need to be replaced with matching tooth pitches. In this embodiment, the first thread-straightening quick-change comb teeth 0003 and the second thread-straightening quick-change comb teeth 0004 are set as detachable structures, which can meet the above-mentioned replacement needs and expand the scope of application of the present invention.

[0211] More specifically, the second two-finger opening and closing gripper 0001 is a two-finger pneumatic gripper, the backlash adjustment and telescopic actuator 00023 is a telescopic cylinder 0141, and the wire-straightening and lifting actuator 0005 is a telescopic cylinder. In this embodiment, all power components are pneumatically driven, facilitating the realization of a single pneumatic system for all power sources. Of course, the second two-finger opening and closing gripper 0001, the backlash adjustment and telescopic actuator 00023, and the wire-straightening and lifting actuator 0005 can also be electrically or hydraulically driven.

[0212] The flattening full circle transfer unit 1000 also includes: a three-axis transfer module 00004, a clamping execution terminal 00002, and a pre-pressing execution terminal 00003. The thread straightening execution terminal 00001, the clamping execution terminal 00002 and the pre-pressing execution terminal 00003 are sequentially loaded side by side on the three-axis transfer module 00004; the clamping execution terminal 00002 includes: a triangular opening and closing chuck 0008, and a chuck lifting drive 0009 for driving the triangular opening and closing chuck 0008 to rise and fall in the Z direction; the pre-pressing execution terminal 00003 includes: a pre-pressing head 0001, a chuck lifting drive 0009 for driving the triangular opening and closing chuck 0008 to rise and fall in the Z direction; The pre-pressing lifting drive 0001 drives the pre-pressing head 0001 to rise and fall along the Z direction; the pre-pressing head 0001 includes: a mounting block 000101, an upper rotating shaft 000102 and a detachable execution pre-pressing rod 000103; the mounting block 000101 is fixedly mounted on 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 to the mounting block 000101 via a bearing, the upper part of the detachable execution pre-pressing rod 000103 is inserted into the upper rotating shaft 000102, and the two are detachably connected.

[0213] In this embodiment, the three-axis transfer module 00004 can be an existing, readily available XYZ-axis transfer module 3, or it can be composed of three unidirectional transfer modules. Ultimately, the three-axis transfer module 00004 can be used to move the clamping actuator 00002, pre-pressing actuator 00003, and thread straightening actuator 00001 loaded thereon to the desired location. The thread straightening actuator 00001, clamping actuator 00002, and pre-pressing actuator 00003 can independently extend and retract in the Z direction, with only one module extending at a time.

[0214] The working process of the flattened full circle transfer unit 1000 is described in detail below:

[0215] First, the rule wire block 200 is located at the flattening station, and the flattening device clamps the lower part of the rule wire block 200. The thread straightening execution terminal 00001 extends to straighten the thread end at the top of the rule wire block 200 (refer to the above content for the specific process). The thread straightening execution terminal 00001 is retracted upward to the top of the three-axis transfer module 00004 under the action of the thread straightening lifting drive 0005.

[0216] Then, the chuck lifting drive 0009 extends downward, driving the clamping actuator 00002 to move downward to the flattening station and clamp the coil body 304. The flattening device opens, and the clamping actuator 00002 is driven to move to the full circle station under the action of the three-axis transfer module 00004, completing the transfer of the rule wire block 200 from the flattening station to the full circle station. Under the action of the chuck lifting drive 0009, it is retracted upward to above the three-axis transfer module 00004.

[0217] The pre-stressing lifting drive 0001 extends downward, and the pre-stressing execution terminal 00003 extends into the full circle station. The full circle station includes a heating and shaping column 000012. The middle section of the sheet-like hollow cup coil is tangent to the outer side of the heating and shaping column 000012. One end of the lower part of the rule wire block 200 is fixed, and the other end is a free end. Under the action of the three-axis transfer module 00004, the clamping execution terminal 00002 moves and squeezes the free end of the rule wire block 200, and deforms the free end along the shape of the wound heating and shaping column 000012. The use of the pre-stressing execution terminal 00003 can complete the pre-deformation of the rule wire block 200 before the formal full circle, thereby ensuring the smoothness and quality of the subsequent full circle deformation. It is especially suitable for hollow cup coils that are thicker and difficult to deform in one time.

[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 on 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 to the mounting block 000101 through a bearing, 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 this embodiment, the upper rotating shaft 000102 is rotatably connected to the mounting block 000101 via a bearing, which can ensure the smoothness of the rotation of the upper rotating shaft 000102. The detachable execution pre-compression rod 000103 is detachably connected to the upper rotating shaft 000102. The lower part of the detachable execution pre-compression rod 000103 is cylindrical. During specific implementation, detachable execution pre-compression rods 000103 of different diameters can be installed as needed to meet usage requirements. The detachable execution pre-compression rod 000103 is rotatable. When the lamellar hollow cup coil is pre-compressed, the action mechanism of the detachable execution pre-compression rod 000103 is to squeeze the lamellar hollow cup coil while rotating itself. In this way, wear on the surface of the lamellar hollow cup coil can be avoided. This further ensures the quality of the product.

[0220] The flattened full circle transfer unit 1000 integrates the functions of straightening, clamping and pre-pressing. Compared with conventional coil production devices, it adds the functions of straightening the straight head after flattening and pre-pressing deformation before rounding, which greatly improves the forming accuracy of the product. The flattened full circle 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 terminal 00002. The three execution terminals share a set of three-axis transfer modules 00004, which has a compact and reasonable structure and is also conducive to reducing costs.

[0221] It should be noted that the first thread end 301 , the second thread end 302 , and the third thread end 003 are all full-strand thread ends 105 , and one of the first thread end 301 , the second thread end 302 , and the third thread end 003 is formed by winding two half-strand thread ends 104 to be twisted together.

[0222] The process of producing hollow cup motor coils using the present invention is as follows: winding → twisting and flattening → cutting the wire ends → flattening and shaping → brushing → dipping in alcohol → rolling → twisting the wire ends → cutting the tail wires → dipping in tin → dipping in alcohol → rounding → electrical inspection → finished product off the line. The present invention designs the devices for implementing each process. For example, in the twisting and flattening process, the added first inner pressure plate 112 and second inner pressure plate 122 and the opening and closing clamping head assembly 13 effectively prevent the wire bundle and the wire ends from slipping and misaligning during the twisting and flattening process of the hollow coil 100, thereby ensuring the twisting and flattening forming effect. A flattening and shaping module is also provided during the twisting and flattening process to further ensure the accuracy of the flattening. The thread straightening execution terminal 00001 in the flattened full circle transfer unit 1000 is used to straighten the thread ends to ensure the position accuracy of the thread ends. The pre-pressing lifting drive 0001 in the flattened full circle transfer unit 1000 can also cooperate with the winding module 0100. Before the formal winding, a pre-pressing deformation process can be performed first, which can improve the winding success rate and forming accuracy of thick hollow cup coils. In addition, the full circle module 0200 is added on the basis of the winding module 0100, which can greatly improve the accuracy of the product. The addition of the electrical inspection unit 900 can automatically detect the products produced online while avoiding coil deformation. The detection accuracy is high and the overall production efficiency is improved.

[0223] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium; it can mean internal communication between two elements, or a "transmission connection," i.e., a power connection through various appropriate means such as a belt drive, a gear drive, or a sprocket drive. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
