Description

Technical Field

[0001] This application relates to the field of coil processing technology, and in particular to a forming device for motor coils. Background Technology

[0002] Currently, an electric motor is a device that converts electrical energy into mechanical energy. Its core components are the stator and rotor, and the coils (made of insulated copper wire) in the stator or rotor are key components. When energized, they generate a magnetic field, which drives the rotor to rotate (electric motor) or generates electricity through electromagnetic induction (generator). The winding method (such as centralized or distributed) and installation location (stator or rotor) of the coils vary depending on the type of motor. For example, DC motors use brush commutation, brushless motors rely on electronic controllers, while AC motors use three-phase windings to generate a rotating magnetic field. The insulation performance, conductivity, and heat dissipation design of the coils directly affect the motor performance. Common faults include short circuits, open circuits, and insulation aging.

[0003] Coils typically use highly conductive copper wire, with the surface of the wire coated with insulating varnish to prevent short circuits during motor operation. The conductors in the motor rotor (such as in wound rotors or DC motor armature windings) need to be conductive at both ends, primarily based on the principles of electromagnetic interaction and current loop requirements. Therefore, during processing, the insulating varnish at both ends of the copper wire needs to be removed before the wire is bent into the specified shape.

[0004] Regarding the aforementioned technologies, the inventors believe that manually removing the insulating varnish and then cutting and bending the copper wire is inefficient and affects the coil processing efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a forming device for motor coils, which solves the technical problem that the efficiency of manually removing insulating varnish and then cutting and bending copper wire is low and affects the coil processing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A forming device for motor coils includes: a frame for supporting the forming device; a stripping assembly mounted on the frame for stripping insulating varnish from copper wire; a scraping assembly mounted on the frame near the stripping assembly for scraping insulating varnish off the copper wire; a driving assembly mounted on the frame near the scraping assembly for driving the copper wire forward on the frame; a cutting assembly mounted on the frame near the driving assembly for cutting the copper wire; a bending assembly mounted on the frame near the cutting assembly for bending the copper wire; and a forming assembly mounted on the frame near the bending assembly for forming the bent copper wire.

[0008] Furthermore, the stripping assembly includes a laser emitter, and several laser emitters are spaced apart around the copper wire, with the output light paths of the several laser emitters pointing towards the surface of the copper wire.

[0009] Furthermore, the paint scraping assembly includes a paint scraping cylinder, which is mounted on the frame. One end of the piston rod of the paint scraping cylinder is provided with a scraper, which presses against the copper wire.

[0010] Furthermore, the drive assembly includes a slide block slidably mounted on the frame, a first clamping block and a second clamping block are provided on the slide block, a copper wire passes through the first clamping block and the second clamping block, and a clamping cylinder is provided on the slide block, the clamping cylinder driving the second clamping block to move closer to the first clamping block.

[0011] Furthermore, the cutting assembly includes a cutting motor mounted on the frame, and a cutting blade is provided on the cutting motor for cutting copper wires.

[0012] Furthermore, the bending assembly includes a first bending block and a second bending block, and a bending plate is provided on the side of the frame near the second bending block. The bending plate drives the second bending block to move towards the side near the first bending block.

[0013] Furthermore, the molding component includes a first molding block and a second molding block, a molding cylinder is provided on the frame, the second molding block is mounted on the molding cylinder, and the molding cylinder drives the second molding block to move toward or away from the first molding block.

[0014] In summary, this application includes at least one of the following beneficial technical effects of the motor coil forming equipment:

[0015] 1. In use, the copper wire is sequentially passed through the stripping component, the paint scraping component, the drive component, the cutting component, the bending component, and the forming component. The drive component drives the copper wire to move forward continuously. The stripping component strips the insulating paint from the copper wire. Then the paint scraping component scrapes off the insulating paint from the copper wire. After that, the cutting component cuts the copper wire into several segments. Then the bending component bends the copper wire. Finally, the forming component shapes the bent copper wire. This eliminates the need to manually remove the insulating paint and improves the processing efficiency of the copper wire.

[0016] 2. By combining a laser emitter with a paint-scraping cylinder and a scraper, the removal effect of insulating varnish on copper wires is improved;

[0017] 3. By setting up the first bending block and the second bending block, as well as the first forming block and the second forming block, the forming efficiency of copper wire is improved. Attached Figure Description

[0032] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a forming device for motor coils.

[0035] Reference Figure 1 A forming device for motor coils includes a frame 1, on which a stripping component 2, a paint scraping component 3, a drive component 4, a cutting component 5, a bending component 6, and a forming component 7 are sequentially arranged. The stripping component 2 and the paint scraping component 3 scrape off the insulating varnish from the copper wire, and the drive component 4 drives the copper wire forward. The cutting component 5 cuts the copper wire, and the bending component 6 and the forming component 7 form the cut copper wire.

[0036] Reference Figure 2 A straightening wheel 11 is provided on one side of the frame 1. The straightening wheels 11 are arranged opposite each other, and several groups of straightening wheels 11 are arranged at intervals on one side of the frame 1. In use, the copper wire passes between two oppositely arranged straightening wheels 11 and is straightened by the straightening wheels 11, so that the subsequent processing effect of the copper wire is improved.

[0037] The copper wire has a rectangular cross-section. The stripping assembly 2 includes four laser emitters 21 spaced around the copper wire. The output beams of the four laser emitters 21 point towards the surface of the copper wire. Since the actual finished copper wire only requires the removal of insulating varnish at the two ends of the leads, the laser emitters 21 operate intermittently. When it is necessary to remove the insulating varnish at a specific location on the copper wire, the laser emitter 21 emits a laser beam towards the surface of the copper wire. After the laser beam is focused, the energy acts on the surface of the insulating varnish in a very short time, causing its temperature to rise sharply and reach the decomposition threshold. The molecular bonds of the insulating varnish break, forming tiny particles that are then peeled off from the surface of the copper wire.

[0038] Reference Figures 3-4 To improve the efficiency of removing the insulating varnish from the copper wire surface, two sets of varnish-scraping components 3 are spaced apart. The copper wire passes through the two sets of varnish-scraping components 3 sequentially. During use, the first set of varnish-scraping components 3 cuts both ends of the copper wire to be varnished. Then, the second set of varnish-scraping components 3 presses against one end of the cut insulating varnish and drives the component 4 to pull the copper wire. When the second set of varnish-scraping components 3 moves to the other end of the cut insulating varnish, the varnish-scraping components 3 release the copper wire. The varnish-scraping components 3 include a varnish-scraping cylinder 31 and a scraper 32, and two sets of varnish-scraping components 3 are spaced apart on the frame 1. The two sets of varnish-scraping components 3 simultaneously scrape off the insulating varnish on the copper wire.

[0039] Furthermore, the frame 1 is slidably mounted with a slide plate 33, and two sets of slide plates 33 are spaced apart. The two sets of paint scraping components 3 are respectively mounted on the two slide plates 33. A first drive motor 331 and a first gear 332 are provided on the slide plate 33, and a first rack 333 is provided on the frame 1. The first gear 332 meshes with the first rack 333. In use, the first drive motor 331 drives the first gear 332 to rotate. As the first gear 332 rotates, the slide plate 33 slides on the frame 1. As the slide plate 33 slides, the distance between the two sets of paint scraping components 3 can be adjusted, so that when processing copper wires of different lengths, the paint scraping components 3 can adapt to copper wires of different lengths.

[0040] Furthermore, four paint scraping cylinders 31 are arranged at intervals around the copper wire on the corresponding slide plate 33. The four paint scraping cylinders 31 correspond to the side wall of the copper wire. In use, the four paint scraping cylinders 31 drive the scraper 32 to press against the copper wire. As the slide plate 33 slides, the scraper 32 scrapes off the insulating paint on the surface of the copper wire.

[0041] To improve the stability of the copper wire during the coating removal process, a positioning cylinder 334 is installed on the side of the frame 1 near the slide plate 33. A first positioning block 341 is mounted on the positioning cylinder 334, and a second positioning block 342 is installed on the side of the frame 1 near the first positioning block 341. The copper wire passes between the first positioning block 341 and the second positioning block 342. When it is necessary to remove the insulating varnish from the copper wire, the positioning cylinder 334 drives the first positioning block 341 to move closer to the second positioning block 342. The first positioning block 341 and the second positioning block 342 clamp the copper wire. After the copper wire is clamped, the two sets of coating removal components 3 then scrape off the insulating varnish from the surface of the copper wire. This reduces the displacement of the copper wire on the frame 1 during the removal of the insulating varnish.

[0042] In addition, the drive assembly 4 is used to drive the copper wire forward on the frame 1. To improve the stability of the copper wire conveying on the frame 1, two sets of drive assemblies 4 are arranged at intervals on the frame 1. The drive assembly 4 includes a slide 41, on which a second drive motor is mounted. A second gear 42 is provided on the output shaft of the second drive motor. A second rack 43 is mounted on the frame 1. The second gear 42 meshes with the second rack 43. In use, the second drive motor drives the second gear 42 to rotate. As the second gear 42 rotates, the slide 41 slides along the second rack 43 on the frame 1.

[0043] Furthermore, the slide 41 is provided with a first clamping block 44 and a second clamping block 45. The first clamping block 44 is fixedly installed on the slide 41. The slide 41 is also equipped with a clamping cylinder 46, which is vertically arranged. The second clamping block 45 is installed on the clamping cylinder 46. In use, the copper wire passes between the first clamping block 44 and the second clamping block 45. When it is necessary to pull the copper wire forward, the clamping cylinder 46 drives the second clamping block 45 to move closer to the first clamping block 44. After the first clamping block 44 and the second clamping block 45 clamp the copper wire, the second drive cylinder drives the slide 41 to slide, thereby causing the first clamping block 44 and the second clamping block 45 to move the copper wire on the frame 1.

[0044] Reference Figures 5-6 Before processing, the copper wire is quite long and needs to be cut into several pieces of the appropriate length. Therefore, the cutting assembly 5 includes a cutting motor 51 and a cutting blade 52. A support base 53 is provided on the frame 1. After the copper wire has been coated, it passes through the support base 53. A pressure plate 54 is provided on the cutting blade 52, and a pressure groove 55 is opened on the pressure plate 54. An eccentric wheel 56 is provided on the output shaft of the cutting motor 51. The eccentric wheel 56 is rotatably installed in the pressure groove 55. As the cutting motor 51 rotates, the pressure plate 54 driven by the eccentric wheel 56 slides on the support base 53. As the pressure plate 54 slides, the cutting blade 52 cuts the copper wire.

[0045] When the cutting blade 52 is used to cut the copper wire, the cutting blade 52 cuts the middle part of the scraped part of the copper wire. After cutting, the scraped copper wire on both sides of the cutting blade 52 forms the pins of two coils, thereby improving the processing efficiency of the coil.

[0046] In order to ensure that the cut copper wires can be transported in an orderly manner, a first conveying rod 57 is provided on the side of the frame 1 near the support base 53. A first conveying channel 571 is formed on the first conveying rod 57. The copper wires enter the first conveying channel 571 of the first conveying rod 57. After the cutting blade 52 cuts the copper wires, the subsequent copper wires push the cut copper wires to move away from the support base 53.

[0047] A rotating disk 61 is mounted on the frame 1. Four sets of bending assemblies 6 are arranged at intervals on the rotating disk 61. As the rotating disk 61 rotates, the copper wires on the first conveying rod 57 are sequentially conveyed to the bending assemblies 6, which then bend the copper wires. Since the four sets of bending assemblies 6 have the same structure and function, only one set of bending assemblies 6 will be described below.

[0048] The bending assembly 6 includes a processing base, on which a first bending block 62 and a second bending block 621 are mounted. The first bending block 62 is fixedly mounted on the processing base, and the second bending block 621 is spaced apart from the first bending block 62, with a bending groove 622 formed between them. A second conveying rod 63 is mounted on the processing base, and a second conveying channel 631 is formed within the second conveying rod 63. One end of the second conveying channel 631 communicates with the bending groove 622. As the rotating disk 61 rotates, the other end of the second conveying channel 631 communicates with the first conveying channel 571 on the first conveying rod 57. This allows the cut copper wire to enter the second conveying rod 63.

[0049] To improve the ease of conveying copper wire on the first conveying rod 57 and the second conveying rod 63, a transverse slide rail 64 is provided on the side of the frame 1 near the support base 53. The first conveying rod 57 is mounted on the transverse slide rail 64. Furthermore, a transverse motor 641 and a transverse screw 642 are provided on the frame 1. The transverse motor 641 is mounted on the frame 1. One end of the transverse screw 642 is connected to the transverse motor 641, and the other end passes through the first conveying rod 57. The transverse screw 642 is threadedly connected to the first conveying rod 57. When it is necessary to convey copper wire to the second conveying rod 63, the transverse motor 641 drives the first conveying rod 57 to move laterally through the transverse screw 642, so that the first conveying rod 57 and the second conveying rod 63 are connected.

[0050] Furthermore, a pusher plate 65 is provided on the side of the frame 1 near the first conveyor rod 57 and the second conveyor rod 63. One end of the pusher plate 65 is inserted into the second conveying channel 631 of the second conveyor rod 63, and then the pusher plate 65 pushes the copper wire toward the side near the bending groove 622.

[0051] The frame 1 is equipped with a push motor 651 and a push screw 652. The push motor 651 is mounted on the frame 1. One end of the push screw 652 is connected to the push motor 651, and the other end passes through the push plate 65. The push screw 652 is threadedly connected to the push plate 65. In use, the push motor 651 drives the push plate 65 to slide on the second conveyor rod 63.

[0052] A bending plate 66 is slidably mounted on the side of the frame 1 near the rotating disk 61. The bending plate 66 is used to drive the second bending block 621 to move closer to the first bending block 62, so that copper wire is formed between the first bending block 62 and the second bending block 621.

[0053] Reference Figure 6 The forming component 7 includes a first forming block 71 and a second forming block 72. After the copper wire is bent, it is placed on the first forming block 71. Two second forming blocks 72 are spaced apart, one of which is perpendicular to the first forming block 71, and the other is parallel to the first forming block 71. In use, the two second forming blocks 72 move towards the side closer to the first forming block, so that the copper wire is formed on the first forming block 71. Further, an output rod 73 is provided on one side of the first forming block 71. One end of the output rod 73 is connected to the first forming block 71. After the copper wire is formed, the horizontal second forming block 72 continues to advance, pushing the formed cylindrical wire toward the output rod 73.

[0054] Furthermore, to enable the copper wire on the second conveying rod 63 to move onto the first forming block 71, a slide rod 74 is provided on the side of the frame 1 near the first forming block 71, with one end of the slide rod 74 extending towards the turntable. A first gripper 75 is provided on the side of the frame 1 near the turntable, which places the copper wire between the first bending block 62 and the second bending block 621 onto the slide rod 74. The copper wire moves with the slide rod 74 to the side of the first forming block 71. A second gripper 76 is provided on the side of the frame 1 near the first forming block 71, which grips the copper wire on the slide rod 74 and places it onto the first forming block 71.

[0055] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
