[0021] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0022] like Figures 1 to 7As shown, it is a schematic diagram of the structure of the shaping device of the motor coil insulation film provided by the present invention. The shaping device of the motor coil insulation film includes a machine platform 10, a pushing mechanism 20 arranged on the machine platform 10, and at least one shaping mechanism 30 arranged on the machine platform 10. It can be imagined that the shaping device of the motor coil insulation film also includes some other functional modules, such as connecting components and mounting components, etc., which are well known to those skilled in the art and will not be repeated here.

[0023] First of all, it should be noted that the shaping device of the motor coil insulation film is used to shape the insulation film of the stator. Figure 7 The stator 100 is in an I-shaped structure, and the grooves on both sides of the stator 100 are provided with insulating films 200 and wound with coils (not shown). The stator 100 and the insulating film 200 should be prior art, and will not be described in detail here.

[0024] The machine 10 is used to carry the above-mentioned functional modules, namely the pushing mechanism 20 and the shaping mechanism 30. Therefore, the machine 10 is provided with a variety of functional structures, such as screws, avoidance holes, clamps, etc. to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs and will not be described in detail one by one here.

[0025] The pushing mechanism 20 includes a driving device 21 disposed on the machine platform 10 , two slide rail and slider assemblies 22 disposed on the machine platform 10 , and a pushing assembly 23 disposed on the slide rail and slider assemblies 22 .

[0026] The driving device 21 is used to drive the pushing component 23 to slide on the slide rail slider component 22. The driving device 21 is arranged at the bottom of the machine platform 10 and passes through the machine platform 10 to be connected with the pushing component 23. Therefore, an avoidance hole is also provided on the machine platform 10 to provide the space required for the driving device 21 to move. The driving device 21 is a screw driving device in this embodiment, which drives the screw to rotate through the driving motor to convert the rotational motion into linear motion, thereby driving the pushing component 23 to slide back and forth on the slide rail slider component 22. The driving device 21 should be a prior art and will not be described in detail here.

[0027] The slide rail and slider assembly 22 is composed of a slide rail and a slider and is located on both sides of the machine platform 10 .

[0028] The pushing assembly 23 includes a slide bar 231 slidably disposed on the slide rail and slider assembly 22, a positioning plate 232 disposed on the machine 10, and at least one push rod 233 disposed on the slide bar 231. The two ends of the slide bar 231 are respectively slidably disposed on the slide rail and slider assembly 22 and connected to the driving device 21. The positioning plate 232 is located between the slide rail and slider assembly 22 and the shaping mechanism 30. The positioning plate 232 is used to pass the push rod 233 and support one end of the push rod 233 to prevent the push rod 233 from sagging or shaking during the movement. One end of the push rod 233 is disposed on the slide bar 231, and the other end is movably passed through the positioning plate 232 and is provided with a push block 234. When the slide bar 2311 moves toward or away from the shaping mechanism 30 under the drive of the driving device 21, it can drive the plurality of push rods 233 to move together, so that the push block 234 abuts against the stator and pushes the stator to move, so that the stator enters the shaping mechanism 30. In this embodiment, the number of the push rods 233 is six, and six stators are processed at the same time. The number can be set according to actual needs.

[0029] In this embodiment, since six stators are processed simultaneously, six shaping mechanisms 30 are arranged side by side, and each shaping mechanism 30 corresponds to one push rod 233. The shaping mechanism 30 includes a guide assembly 31, a heating assembly 32 arranged on the guide assembly 31, and a cooling assembly 33 arranged on the heating assembly 32.

[0030] The guide assembly 31 includes a base plate 311, a slide groove 312 arranged on the base plate 311, two guide blocks 313 arranged on the base plate 311, two limit blocks 314 arranged on the base plate 311, and a plurality of pins 315 connecting the base plate 311 and the limit blocks 314.

[0031] The extension direction of the slide 312 is close to or away from the heating component 32, and the stator to be processed will be placed in the slide 312 by a robot. The two guide blocks 313 are located on both sides of the slide 312, and the two ends of the guide blocks 313 are provided with inclined surfaces 3131 connected with the bottom plate 311. An extension part 3132 extends from the opposite sides of the two guide blocks 313, and the extension distance of the extension part 3132 gradually increases from the end close to the bottom plate 311 to the end away from the bottom plate 311, so that the distance between the two extension parts 3132 gradually increases from the bottom to the top. When the push block 234 pushes the stator to slide in the slide 312, the insulating film of the lower layer of the stator will first contact the inclined surface 3131 and gradually rise under the action of the inclined surface 3131, thereby determining the bending direction and guiding the insulating film to avoid paper jams. At the same time, due to the existence of the extension portion 3132 , as the stator continues to be pushed, the raised insulating film will be squeezed by the extension portion 3132 and bent.

[0032] The limiting block 314 includes a forming block 3141 disposed on the bottom plate 311 , a pressing block 3142 integrally disposed with the forming block 3141 , and a guiding inclined surface 3143 disposed at the connection between the forming block 3141 and the pressing block 3142 .

[0033] The forming block 3141 is located between the bottom plate 311 and the pressing block 3142. The cross section of the forming block 3141 is a right-angled trapezoid, and the oblique waist of the right-angled trapezoid is located on the opposite sides of the two limiting blocks 314. The distance between the two forming blocks 3141 gradually increases from the end close to the bottom plate 311 to the end away from the bottom plate 311, so that the opposite sides of the two forming blocks 3141 are the same as the extension part 3132, and are also protrudingly arranged to bend the upper insulating film. The guiding inclined surface 3143 is located at the end of the forming block 3141 close to the guiding block 313, and its function is the same as that of the inclined surface 3131, and is used to guide the insulating film of the upper layer of the stator. As the stator continues to move, the insulating film on the upper layer of the stator will first contact the guide slope 3143 and bend downward under force, and then bend under the compression of the forming block 3141, thereby realizing the bending of the upper and lower ends of the insulating film, and first bend the lower end insulating film and then bend the upper end insulating film, so that the bending of the upper and lower ends is carried out in steps and will not be jammed. The pressing block 3142 is used to press the stator to prevent the stator from escaping from the slide slot 312. The latch 315 is set on the bottom plate 311, and the forming block 3141 is inserted on the latch 315, thereby connecting the bottom plate 311 and the limit block 314.

[0034] The heating assembly 32 is located between the guide assembly 31 and the cooling assembly 33. The heating assembly 32 includes a heating shell 321 disposed on the machine 10, a heating channel 322 disposed on the heating shell 321, and a plurality of heating tubes 323 disposed on the heating shell 321. The heating channel 322 runs through the heating shell 321 and is connected to the slide 312. It can be imagined that the shape of the heating channel 322 should be the same as the shape of the stator after the insulating film is bent, so that the insulating film is always squeezed in the heating channel 322 to ensure the shaping effect. The heating tube 323 is used to heat the heating shell 321. When the stator after the insulating film is bent is pushed into the heating channel 322 by the pushing assembly 23, the heating tube 323 is heated, so that the temperature of the heating shell 321 is increased and the bent insulating film is heat-set.

[0035] The cooling component 33 includes a shaping film 331 disposed on the machine 10, a shaping channel 332 disposed on the shaping film 331, and a blowing device 333 disposed on the shaping film 331. The shaping channel 332 runs through the shaping film 331 and is connected to the heating channel 322. The shape of the shaping channel 332 is the same as that of the heating channel 322, thereby fixing the insulating film. The blowing direction of the blowing device 333 is toward the shaping channel 332. When the stator is pushed out of the heating component 32 by the pushing component 23 and enters the shaping channel 332, the blowing device 333 performs air cooling on the stator in the shaping channel 332, thereby accelerating the cooling of the insulating film. At the same time, the insulating film can also be shaped again during the cooling process to improve the shaping strength of the insulating film and avoid rebound.

[0036] Compared with the prior art, the two ends of the guide block 313 of the shaping device for the motor coil insulation film provided by the present invention are provided with inclined surfaces 3131 connected with the bottom plate 311, and an extension portion 3132 extends from the opposite sides of the two guide blocks 313, and the extension distance of the extension portion 3132 gradually increases from the end close to the bottom plate 311 to the end away from the bottom plate 311. The distance between the two forming blocks 3141 gradually increases from the end close to the bottom plate 311 to the end away from the bottom plate 311, and the guiding inclined surface 3143 is located at the end of the forming block 3141 close to the guiding block 313. The insulation films at the upper and lower ends of the stator can be bent step by step, and there are inclined surfaces for guidance, so that there will be no paper jams and mutual influence, and the automatic bending of the insulation films at both ends of the stator is realized. After that, the bent insulation film is heat-shaped by the heating component 32, and then the cooling component 33 is cooled. During the cooling process, the insulation film can also be shaped again, so that the overall shaping effect is good.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
