[0002] Coreless motors, as a type of miniature servo DC motor widely used in many fields, possess a unique structure and excellent performance. The coreless motor coil, one of its core components, plays a decisive role in the overall performance of the motor.

[0003] In the manufacturing process of motor coils, it is necessary to round the coils that have been flattened into coil blocks (also known as "rolling"). In the prior art, Chinese Patent Publication No. CN217521851U discloses a hollow cup motor coil processing equipment, including a coil winding device, a coil flattening device, and a coil rounding device. The coil rounding device includes a processing platform, a heating and shaping column, a rounding lever, a lever driving mechanism, and rounding blocks. The lever driving mechanism drives the rounding lever to rotate around the heating and shaping column. The lever driving mechanism is also equipped with a coil clamping mechanism. There are multiple rounding blocks arranged in a circumferential array relative to the heating and shaping column on the periphery of the heating and shaping column. Each rounding block is driven and connected by a straight-line driving mechanism.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0045] The following is in conjunction with the appendix Figure 1-8 The present invention provides a further description of the coil tinning and shaping device for a hollow cup motor coil production line.

[0046] Please refer to this carefully. Figure 1-5 This utility model discloses a coil tinning and shaping device for a hollow cup motor coil production line, including a coil coarse rolling device 100 for achieving coarse rolling of the hollow cup motor coil, wherein the coil tinning and shaping device for the hollow cup motor coil production line further includes a coil fine rolling device 200 disposed on one side of the coil coarse rolling device 100 for achieving fine rolling of the hollow cup motor coil; the coil fine rolling device 200 includes: a workbench assembly 21, a shaping rod 22, a rotary drive unit 23, a telescopic drive unit 24, a left pressure mold unit 25, and a right pressure mold unit 26; the workbench assembly 21 includes a support plate 211, the support plate 211 is arranged horizontally, the upper part of the shaping rod 22 passes through the support plate 211, and the rotary drive unit 23 is connected to the lower part of the shaping rod 22. It is used to drive the shaping rod 22 to rotate; the telescopic drive unit 24 is connected to the rotation drive unit 23 and is used to drive the rotation drive unit 23 and the shaping rod 22 to rise and fall as a whole; the left pressing unit 25 includes: a first telescopic hot press plate assembly, and 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 extend and retract; the right pressing unit 26 includes: a second telescopic hot press plate assembly, and 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 extend and retract; the first telescopic hot press plate assembly and the second telescopic hot press plate assembly are arranged opposite to each other on both sides of the upper part of the shaping rod 22, and the first telescopic hot press plate assembly and the second telescopic hot press plate assembly together form a pressing cavity that matches the shape of the outer side of the hollow cup motor coil.

[0047] In this embodiment, the coil coarse winding device 100 is used to round the regular wire block 01 to obtain a coarsely wound coil 02. The coil coarse winding device 100 can adopt the structure of the prior art. After the regular wire block 01 (which is rolled into a regular flat shape after winding) obtained in the previous process is immersed in alcohol, the regular wire block 01 is beaten into a rough circle by the four heating and shaping blocks 013 in the coil coarse winding device 100 to obtain the coarsely wound coil 02. Then, the wire ends 04 in the coarsely wound coil 02 are immersed in tin and then immersed in alcohol. Finally, the coil fine winding device 200 is used to finely round the coarsely wound coil 02 to obtain a finely rounded coil 03. The finely rounded coil 03 is the final product obtained in production.

[0048] The first telescopic drive 251 and the second telescopic drive 261 can be cylinders or hydraulic cylinders, used to provide linear telescopic power. The rotary drive unit 23 can be a rotary motor or a rotary cylinder, used to provide rotary power.

[0049] The specific process of rounding is as follows: The second robotic arm 600 holds the coarsely wound coil 02 and places it on the shaping rod 22, with the end of the coil facing upwards. The support plate 211 supports the coil 02. Under the action of the first telescopic drive 251 and the second telescopic drive 261, the first and second telescopic hot press plate assemblies extend simultaneously and act directly on the outside of the coil 02 to adjust its shape. Under the action of the first and second telescopic drives 251 and 261, the first and second telescopic hot press plate assemblies retract simultaneously. The rotation drive unit 23 drives the shaping rod 22 to rotate a certain angle and then stops. The first and second telescopic hot press plate assemblies extend and retract simultaneously again and act directly on the outside of the coil 02. After repeating this process multiple times, the rounding process ends, and a rounded coil 03 with higher roundness is obtained. In this state, the rounded coil 03 is wrapped around the shaping rod 22. The telescopic drive unit 24 descends, driving the rotary drive unit 23 to descend along with the shaping rod 22, removing the finished round coil 03 from the shaping rod 22. After the finished round coil 03 is removed, the shaping rod 22 extends again to prepare for the finishing process of the next coarse coil 02.

[0050] Compared with the prior art, 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 press plate assembly and the second telescopic hot press plate assembly act simultaneously on the outer side of the coarse coil 02, the shaping accuracy can be greatly improved. By rotating the angle of the shaping rod 22 multiple times, and performing hot pressing shaping on the outer side of the coarse coil 02 after each rotation, the accuracy of the fine coil 03 is greatly improved. The telescopic drive unit 24 descends, which can separate the shaping rod 22 and the fine coil wrapped around the shaping rod 22, realizing material removal. This facilitates the flexible transfer of the fine coil 03 to the next process, and the material removal direction is downward along the axis of the fine coil 03. With this structure, there is enough space to arrange the telescopic drive unit 24, and the shape of the fine coil 03 is not damaged.

[0051] According to a specific embodiment of this utility model, the pressing cavity is a complete cylindrical shape that matches the outer shape of the hollow cup motor coil. A buffer spring 29 is provided between the first telescopic hot press plate assembly and the second telescopic hot press plate assembly. The coil finishing rounding device 200 also includes a limiting flange 30, which is detachably installed on the support plate 211. The upper part of the shaping rod 22 also passes through the limiting flange 30, and the shaping rod 22 is slidably connected to the limiting flange 30. The upper part of the limiting flange 30 is provided with an annular support step 301 for supporting the bottom of the hollow cup motor coil.

[0052] More specifically, the left molding unit 25 and the right molding unit 26 are symmetrical structures.

[0053] In this embodiment, when the first and second telescopic hot press plate assemblies are fitted together, they form a pressing cavity. With the buffer spring 29 installed, the closer the first and second telescopic hot press plate assemblies are, the greater the spring force they receive, ultimately achieving a smooth fit between the first and second telescopic hot press plate assemblies and avoiding impact.

[0054] The limiting flange 30 can be detachably installed on the support plate 211. In specific implementation, the height of the annular support step 301 of the limiting flange 30 can be reasonably adjusted according to the height of the hollow cup motor coil to ensure that when the first telescopic hot press plate assembly and the second telescopic hot press plate assembly extend, they just squeeze the outer side of the hollow cup motor coil.

[0055] According to a specific embodiment of this utility model, the first telescopic hot press plate assembly includes, in sequence, a first mounting plate 252, a first heat-insulating graphite plate 253, and a first heating plate 254, which are fixedly connected together. A first telescopic drive 251 is mounted on the side of the first mounting plate 252 away from the right-side pressing unit 26.

The second telescopic hot press plate assembly includes, in sequence, a second mounting plate 262, a second heat-insulating graphite plate 263, and a second heating plate 264, which are fixedly connected together. The compression drive 261 is installed on the side of the second mounting plate 262 away from the left pressing unit 25; the second heating plate 264 is provided with a recessed second module receiving groove 2641 on the side near the left pressing unit 25, and the second module receiving groove 2641 is embedded with a second shaping mold 265; the pressing cavity is formed by the first shaping mold 255 and the second shaping mold 265; the buffer spring 29 is located between the first mounting plate 252 and the second mounting plate 262; the first heating plate 254 is embedded with a first electric heating tube 256 and a first thermocouple 257; the second heating plate 264 is embedded with a second electric heating tube 266 and a second thermocouple 267.

[0056] In this embodiment, the first telescopic hot press plate assembly and the second telescopic hot press plate assembly are symmetrical structures, which helps to reduce the number of parts and lower costs.

[0057] The first shaping mold 255 is embedded in the first module receiving slot 2541. The first shaping mold 255 is a replaceable structure, and different first shaping molds 255 can be flexibly replaced according to different hollow cup motor coil sizes to obtain the shape of the corresponding pressing cavity. The first electric heating tube 256 is used to heat the first heating plate 254, and the first thermocouple 257 is used to detect the temperature of the first heating plate 254. Combined with the control circuit, the temperature of the first heating plate 254 is controlled, ultimately achieving hot pressing shaping of the hollow cup motor coil within a preset temperature range. The first mounting plate 252 serves as the mounting base for the first heat-insulating graphite plate 253 and the first heating plate 254, and is also used to connect the first telescopic drive 251 and the first mounting plate 252. The structure and function of the second telescopic hot press plate assembly are described above for the first telescopic hot press plate assembly.

[0058] According to a specific embodiment of this utility model, the first telescopic drive 251 is a pneumatic cylinder or a hydraulic cylinder; the second telescopic drive 261 is a pneumatic cylinder or a hydraulic cylinder; the coil finishing rounding device 200 further includes a spring positioning rod 27; the worktable assembly 21 further includes a first vertical mounting plate 212 and a second vertical mounting plate 213 disposed opposite to each other on both sides of the support plate 211; one end of the spring positioning rod 27 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 27 passes through the second mounting plate 262 and... The first mounting plate 252 and the second mounting plate 262 are fixed to the second vertical mounting plate 213. The first mounting plate 252 and the second mounting plate 262 are slidably connected to the spring positioning rod 27. The buffer spring 29 is sleeved on the spring positioning rod 27, and the two ends of the buffer spring 29 abut against the first mounting plate 252 and the second mounting plate 262 respectively. 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.

[0059] In this embodiment, the spring positioning rod 27 can limit the position of the buffer spring 29, ensuring the stability of its extension and retraction. In use, the first extension drive 251 drives the first mounting plate 252 to slide along the spring positioning rod 27, and the first mounting plate 252 compresses one end of the buffer spring 29; at the same time, the second extension drive 261 drives the second mounting plate 262 to slide along the spring positioning rod 27, and the second mounting plate 262 compresses the other end of the buffer spring 29.

[0060] According to a specific embodiment of the present invention, both the first mounting plate 252 and the second mounting plate 262 are rectangular, and there are four spring positioning rods 27. The four spring positioning rods 27 are located at the four corners of the first mounting plate 252, and each spring positioning rod 27 is fitted with a buffer spring 29. The first heat-insulating graphite plate 253, the first heating plate 254, the second heat-insulating graphite plate 263, and the second heating plate 264 are all located within the space enclosed by the four spring positioning rods 27.

[0061] In this embodiment, four buffer springs 29 are provided at the corners of the first mounting plate 252 and the second mounting plate 262, and the four buffer springs 29 are arranged around the first heating plate 254 and the second heating plate 264, which helps to provide uniform buffering force and ensure the smoothness of the extension and retraction of the first telescopic hot press plate assembly and the second telescopic hot press plate assembly.

[0062] According to a specific embodiment of this utility model, the workbench assembly 21 further includes: an inner support frame 214 disposed below the support plate 211, and an outer support frame 215 disposed around the inner support frame 214. Both the inner support frame 214 and the outer support frame 215 are rectangular frames with openings at the top. A set of slide rails 28 is 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 rotary drive unit 23 includes a rotary 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 22 via a coupling. The telescopic drive unit 24 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.

[0063] In this embodiment, the inner support frame 214 is a rectangular frame with an opening at the top, and the outer frame is a rectangular frame with an opening at the top formed by offsetting the inner frame outwards. This structure creates a gap between the sidewalls of the inner support frame 214 and the outer support frame 215, allowing for symmetrical installation of the slide rails 28 and ensuring smooth sliding between them. The gap between the sidewalls of the inner support frame 214 and the outer support frame 215 provides space for the extension and retraction of the telescopic drive unit 24.

[0064] In use, the motor shaft rotates, driving the shaping rod 22 to rotate via the coupling, thus meeting the adjustment requirements for the rotation angle of the hollow cup motor coil during the fine shaping process. The cylinder telescopic rod 242 extends and retracts, driving the extension and retraction of the inner support frame 214 and all components mounted on the inner support frame 214, including the shaping rod 22, to achieve the unloading of the hollow cup motor coil.

[0065] Please refer to this carefully. Figure 7 According to a specific embodiment of the present invention, the coil tinning and shaping device for the hollow cup motor coil production line further includes a tinning device 300 located on one side of the coil coarse winding device 100. The tinning device 300 includes: a tin furnace 031, a push plate 032 located above the tin furnace 031, and a tinning telescopic power drive 033 for driving the push plate 032 to extend and retract. The tinning telescopic power drive 033 and the push plate 032 are fixedly connected by a heat insulation plate 034.

[0066] More specifically, the tin furnace 031 is made of titanium alloy to prevent tin from sticking.

[0067] In this embodiment, the tin-immersion telescopic power drive 033 is used to provide telescopic power. It can be a pneumatic or electric telescopic cylinder. In use, before tinning the wire end 04 of the hollow cup motor, the tin-immersion telescopic power drive 033 is used to drive the push plate 032 to extend and retract, so as to remove the oxide layer on the surface of the molten tin in the tin bath 031 and ensure the quality of tinning of the wire end 04.

[0068] According to a specific embodiment of this utility model, the coil tinning and shaping device for a hollow cup motor coil production line further includes: a first alcohol tank 900, a second alcohol tank 500, a first robotic arm 800, a second robotic arm 600, and a turntable 400; the coil finishing and rounding device 200, the tinning device 300, and the turntable 400 are all located on the same side of the coil coarse winding and rounding device 100, the first alcohol tank 900 is located on the other side of the coil coarse winding and rounding device 100, the second alcohol tank 500 is located between the coil finishing and rounding device 200 and the tinning device 300, and the turntable 400 is located between the coil finishing and rounding device 200 and the tinning device 300. The second alcohol tank 500 is located on the side of the turntable 400 away from the coil coarse winding device 100; the area containing the first alcohol tank 900, the coil coarse winding device 100, the tin furnace 031, and the side of the turntable 400 near the tin furnace 031 is designated as the first area; the area containing the side of the turntable 400 near the coil fine winding device 200, the second alcohol tank 500, and the coil fine winding device 200 is designated as the second area; the first robot arm 800 is used to change the position of the hollow cup motor coil in the first area; the second robot arm 600 is used to change the position of the hollow cup motor coil in the second area.

[0069] In this embodiment, when producing hollow cup motor coils using the coil tinning and shaping device for a hollow cup motor coil production line of this utility model, the first robot arm 800 first grabs the regular wire block 01 in the first alcohol tank 900 to complete the alcohol immersion process before coarse rolling, so as to remove impurities, enhance flexibility and improve the bonding performance of the coil after rolling; then the first robot arm 800 grabs the regular wire block 01 and moves it to the coil coarse rolling device 100 to complete the coarse rolling process; then the first robot arm 800 grabs the coarse rolled coil 02 and rotates it 180° so that the wire end 04 is immersed in the tin furnace 031 to complete the tinning process; then the coil after the wire end 04 is immersed in tin is transferred to the turntable 400 near the side of the tin furnace 031.

[0070] The turntable 400 is used to support the hollow cup motor coil after tinning, so that the second robot 600 can grasp the hollow cup motor coil. The second robot 600 grasps the regular wire block 01 in the second alcohol tank 500 to complete the alcohol dipping process before finishing the coil, so as to remove impurities, enhance flexibility and improve the bonding performance of the coil after finishing. Then the second robot 600 grasps the hollow cup motor coil after alcohol dipping and moves it to the coil finishing device 200 to complete the finishing process.

[0071] In this embodiment, by rationally arranging the positions of each component, the volume occupied by the device can be reduced. Utilizing the structure of this embodiment, the processes of first-time alcohol immersion, rough rolling, tin immersion, second-time alcohol immersion, and fine rolling can be realized, greatly improving the quality of the hollow cup motor coil.

A protruding support column 044 is provided on each of the upper two sides of the turntable 043, and the outer diameter of the support column 044 matches the inner diameter of the hollow cup motor coil.

[0073] More specifically, the rotary power 042 can be a rotary motor or a rotary cylinder.

[0074] In this embodiment, the two support columns 044 on the turntable 400 are used to support two hollow cup motor coils. In use, the first robot arm 800 moves the hollow cup motor coil to the support column 044 on the side closest to the solder pot 031. With this structure, the turntable rotation power 042 rotates, transferring the hollow cup motor coil from the side closest to the solder pot 031 to the side closest to the coil finishing device 200. The advantages of this structure include: firstly, it reduces the travel range of the second robot arm 600, further reducing the size of the device; secondly, with the two support columns 044, when the second robot arm 600 picks up the hollow cup motor coil from the coil finishing device 200 side, the first robot arm 800 can simultaneously place the tin-soaked hollow cup motor coil onto the support column 044 on the side of the solder pot 031, avoiding waiting and achieving continuity between the tin-soaking and alcohol-soaking processes, thus ensuring production efficiency.

[0075] Please refer to this carefully.

[0076] In this embodiment, the coarse coiling linear drive 014 extends and retracts, which in turn drives the heating and shaping block 013 to extend and retract, thereby rounding the regular wire block 01 set against the heating and shaping column 012, thus realizing the coarse coiling process. In this embodiment, thermocouples are installed in both the heating and shaping column 012 and the heating and shaping block 013, which can improve the heating speed and uniformity of the regular wire block 01, and help improve the quality of coiling. The automatic wire clip 011 is used to trim the wire ends 04, and the cut-off waste wire ends are collected by the wire collection groove 015.
