Description

Technical Field

[0001] The invention relates to the technical field of coil jigs, and in particular to a multi-layer coil circle assembly mechanism. Background Art

[0002] Coil usually refers to a ring-shaped wire winding. The most common coil applications include: motors, inductors, transformers and ring antennas, etc. Generally, the wires are wound one by one, and the wires are insulated from each other. The motor stator is the stationary part of the motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator winding is to generate a rotating magnetic field, and the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate output current. The stator winding is composed of multiple single stators spliced ​​in a ring shape.

[0003] The prior art circle-making mechanism is generally performed by multiple cylinders distributed in a ring shape. When placing multiple single stators, they are placed on the cylinders respectively. Then, during the circle-making process, multiple cylinders operate simultaneously to bring the multiple single stators together to form a circle. However, since the stators need to be wound before the circle is made, four stators are generally wound together through a wire and then put into a circle. At the same time, they need to be placed at intervals when making a circle, such as Figure 1 As shown. For the above-mentioned circular structure, since the placement positions are all at the same height and cannot be adjusted individually, it is easy to bump into the already placed stators when placing the second and third stator groups, especially when placing the third stator group, at this time there are stators on both sides and the space on both sides is very small, making it difficult for the robot to have operating space, and manual placement has low work efficiency.

DETAILED DESCRIPTION

[0029] 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.

[0030] like Figures 2 to 13 As shown, it is a schematic diagram of the structure of the multi-layer coil circle-joining mechanism provided by the present invention. The multi-layer coil circle-joining mechanism includes a base 10, a driving mechanism 20 arranged on the base 10, and a circle-joining mechanism 30 arranged on the base 10. It can be imagined that the multi-layer coil circle-joining mechanism also includes some other functional modules, such as connection components, sensors, and installation components, etc., which are well known to those skilled in the art and will not be repeated here.

[0031] It should be noted that the multi-layer coil circle assembly mechanism is used to splice multiple stators 100 into a winding. An arc-shaped positioning groove 110 and a positioning convex strip 120 are respectively provided on both sides of the stator 100. The positioning groove 110 on one stator 100 corresponds to the positioning convex strip 120 on the other stator 100, so that the two stators 100 are assembled together, so that several stators 100 are fixedly spliced ​​into a circular winding. A strip groove 130 is opened on one side of the stator 100, and the four stators 100 are wound and connected together by a wire before the circle assembly.

[0032] The center of the base 10 is provided with a support platform 11 for setting the circle-making mechanism 30. The base 10 is used to carry the above-mentioned functional modules, so the base 10 is provided with a variety of functional structures, such as screws, bolts, through holes, etc., to complete the installation and assembly of the above-mentioned functional modules, which can be set according to actual needs and will not be described in detail one by one here. The support platform 11 is used to increase the height of the driving mechanism 20 to adapt to the structure and height of the multi-layer circle-making mechanism 30.

[0033] The driving mechanism 20 includes four guide columns 21 arranged on the base 10, a bottom plate 22 arranged on the guide columns 21, two driving shafts 23 arranged on the bottom plate 22, a moving plate 24 arranged on the driving shaft 23, a driving assembly 25 arranged on the bottom plate 22, a first tooth plate 26 rotatably arranged on the moving plate 24, a first gear 27 arranged on the first tooth plate 26, a second tooth plate 28 rotatably arranged on the base 10, and a second gear 29 arranged on the second tooth plate 28.

[0034] One end of the guide column 21 is connected to the base 10, and the other end is connected to the bottom plate 22. It is used to guide the movement of the movable plate 24 and provide the space required by the movable plate 24. The two ends of the drive shaft 23 are rotatably arranged with the base 10 and the bottom plate 22 respectively, and the outer wall is provided with threads. The four corners of the movable plate 24 are slidably sleeved on the guide column 21, and the two sides of the movable plate 24 are sleeved on the drive shaft 23 and are threadedly connected with the drive shaft 23. The driving assembly 25 is composed of a rotating motor, a belt, and a rotating wheel. The rotating wheel is arranged on the drive shaft 23. The rotating motor drives the rotating wheel to rotate through the belt, thereby controlling the rotation of the drive shaft 23. The rotation of the drive shaft 23 will drive the movable plate 24 to move along the axial direction of the drive shaft 23 through the external thread.

[0035] A plurality of first blocks 261 of different lengths are arranged at intervals on the outer side wall of the first tooth plate 26, so that a sunken groove is formed between two adjacent first blocks 261. A plurality of second blocks 262 of different lengths are arranged at intervals on the inner side wall of the first tooth plate 26, so that a through gap is formed between two adjacent second blocks 262, and the second blocks 262 are provided with two layers, and the first blocks 261 and the second blocks 262 are used to control the circle-making mechanism 30 to slide to blocks of different heights, so that the corresponding circle-making mechanism 30 moves vertically, and the specific description will be described below in conjunction with the circle-making mechanism 30.

[0036] When the first tooth plate 26 rotates, the circle-making mechanism 30 will slide along the first blocks 261 and the second blocks 262. When the circle-making mechanism 30 slides to a groove formed between two adjacent first blocks 261 or the second blocks 262, the circle-making mechanism 30 will drop in height, and when it slides again onto the first blocks 261 or the second blocks 262, the circle-making mechanism 30 will drop in height. Since the circle-making mechanism 30 is a multi-layered circle-making mechanism with a multi-layer moving mechanism, the first tooth plate 26 is used to realize layered control, and a specific description needs to be described below in conjunction with the circle-making mechanism 30.

[0037] The first gear 27 is coaxially arranged with the first tooth plate 26. The first gear 27 is connected to a first driving device 271 arranged on the movable plate 24. The first driving device 271 is a rotating motor and meshes with the first gear 27 through gears. The first driving device 271 drives the first gear 27 to rotate, thereby controlling the rotation of the first tooth plate 26.

[0038] The second tooth plate 28 is rotatably disposed at the bottom of the base 10, and the second tooth plate 28 is coaxially disposed with the first tooth plate 26. A plurality of third stoppers 281 of different lengths are arranged at intervals on the inner and outer side walls of the second tooth plate 28, and a through gap is formed between two adjacent third stoppers 281, and the third stoppers 281 are used to lock the rounding mechanism 30, and the rounding mechanism 30 is provided with corresponding locking grooves at positions corresponding to the third stoppers 281, and the third stoppers 281 are locked into the corresponding locking grooves when the second tooth plate 28 is rotated to achieve locking, and a through gap is formed between the two third stoppers 281 to avoid the rounding mechanism 30 from passing when locking is not required, and a specific description will be described below in conjunction with the rounding mechanism 30.

[0039] The second gear 29 is coaxially arranged with the second tooth plate 28. The second gear 29 is connected to a second driving device 291 arranged on the base 10. The second driving device 291 is a rotating motor and engages with the second gear 29 through gears. The second driving device 291 drives the second gear 29 to rotate, thereby controlling the rotation of the second tooth plate 28.

[0040] The circle-joining mechanism 30 includes a plurality of first circle-joining components 31 movably arranged on the base 10, and a plurality of second circle-joining components 32 movably arranged on the base 10. The coil processed in this embodiment is composed of 12 stators, and four stators 100 are placed each time and connected together by winding a wire, so it needs to be placed three times, so this embodiment also has a plurality of third circle-joining components 33 movably arranged on the base 10 and having the same structure as the second circle-joining components 32. The circle-joining mechanism 30 is arranged in a circular distribution in the order of the first circle-joining components 31, the second circle-joining components 32, and the third circle-joining components 33.

[0041] The first circle assembly 31 includes a mounting plate 311, a first movable shaft 312 arranged on the mounting plate 311, a first guide wheel 313 arranged on the first movable shaft 312, a moving block 314 arranged on the mounting plate 311, a mounting block 315 arranged on the base 10, and a transmission assembly 316 arranged on the moving block 314 and the mounting block 315.

[0042] The mounting plate 311 is annular and is located outside the bearing platform 11. One end of the first movable shaft 312 is connected to the mounting plate 311, and the other end is movably passed through the base 10 and provided with the first guide wheel 313. The first guide wheel 313 is in contact with the first stopper 261. When the first tooth plate 26 rotates, the first guide wheel 313 will slide along the first stoppers 261. When the first tooth plate 26 slides to form a sunken groove between two adjacent first stoppers 261, the first guide wheel 313 will fall, causing the mounting plate 311 to drop in height. When the first guide wheel 313 slides onto the first stopper 261 again, the circle assembly mechanism 30 will reset to the upper and lowered height. In this way, the positions of the first circle assembly 31, the second circle assembly 32 or the third circle assembly 33 can be individually controlled by rotating the first tooth plate 26 at different angles, that is, the first guide wheels 313 of multiple first circle assembly assemblies 31 are all located on the first stop block 261, and the first guide wheels 313 of multiple second circle assembly assemblies 32 are all located in the groove, so that the heights of the first circle assembly 31 and the second circle assembly 32 are slightly different, and when the first tooth plate 26 moves vertically, the heights of all circle assembly assemblies can be controlled at the same time, so as to be raised simultaneously when assembling circles.

[0043] The transmission assembly 316 includes a first connecting rod 3161 having one end movably connected to the moving block 314, a second connecting rod 3162 having one end rotatably connected to the mounting block 315, a third connecting rod 3163 having one end rotatably connected to the mounting block 315, a fourth connecting rod 3164 having one end rotatably connected to the second connecting rod 3162, a fifth connecting rod 3165 rotatably connected to the first connecting rod 3161 and the fourth connecting rod 3164, a locking seat 3166 arranged on the fifth connecting rod 3165, a locking rod 3167 arranged on the locking seat 3166, and an elastic member 3168 arranged on the fifth connecting rod 3165.

[0044] One end of the first connecting rod 3161 is movably connected to the moving block 314, and the other end is rotatably connected to the middle section of the fifth connecting rod 3165. One end of the second connecting rod 3162 is rotatably connected to the mounting block 315, and the other end is rotatably connected to one end of the fourth connecting rod 3164, and the middle position of the second connecting rod 3162 is rotatably connected to the first connecting rod 3161. One end of the third connecting rod 3163 is rotatably connected to the mounting block 315, and the other end is rotatably connected to the middle position of the fourth connecting rod 3164, and the middle position of the third connecting rod 3163 is rotatably connected to the first connecting rod 3161. The elastic member 3168 is provided at one end of the fifth connecting rod 3165, and the locking seat 3166 is provided at the other end. In this way, the end of the first link 3161 close to the moving block 314 makes vertical movement driven by the mounting plate 311, and the second link 3162 and the third link 3163 will swing around the mounting block 315 driven by the first link 3161, so that the fourth link 3164 located at the other end of the second link 3162 and the third link 3163 moves, thereby controlling the rotation of the fifth link 3165 and rotating the locking seat 3166 to a horizontal state or a vertical state to realize a circle-making action.

[0045] The locking seat 3166 is provided with a bar block 31661 matching the bar groove 130, a stop block 31662 located at one end of the locking seat 3166, and a locking groove 31663 provided at one end of the locking seat 3166. The bar groove 130 is clamped on the bar block 31661, and pulleys slidably arranged in the locking groove 31663 are provided on both sides of the locking rod 3167. One end of the locking rod 3167 abuts against the stator 100, and the other end is kept pressed against the stator 100 by the abutment of the elastic member 3168. One end of the stator 100 abuts against the stop block 31662, and is pressed by the locking rod 3167, so that the stator is fixed.

[0046] The structures of the second circle assembly 32 and the third circle assembly 33 are the same as those of the first circle assembly 31, except that the mounting blocks 315 of the second circle assembly 32 and the third circle assembly 33 are movably arranged and are provided with a second movable shaft 317 and a second guide wheel 318 arranged on the second movable shaft 317.

[0047] Since multiple stators 100 need to be placed three times when forming a circle, the first four stators 100 are placed on the first circle assembly 31, and the second circle assembly 32 and the third circle assembly 33 have not yet been placed with stators. Therefore, there will be no interference when placing the first circle assembly 31 at this time. When placing the second circle assembly 32 and the third circle assembly 33, there are already stators on the first circle assembly 31, so it is necessary to raise the circle assembly through the second movable shaft 317 and the second guide wheel 318 to facilitate placement and avoid interference. Specifically, one end of the second movable shaft 317 is connected to the mounting block 315, and the other end is movably arranged through the base 10 and provided with the second guide wheel 318, and the second guide wheel 318 is fitted with the second stopper 262.

[0048] When the second guide wheel 318 is located on the second stopper 262, the height of the second guide wheel 318 is controlled by the vertical movement of the moving plate 24, thereby driving the mounting block 315 to move vertically through the second moving shaft 317. When the first tooth plate 26 rotates, the second guide wheel 318 will slide along the plurality of second stoppers 262, and when the second guide wheel 318 slides to form a through gap between two adjacent second stoppers 262, the second guide wheel 318 will fall, thereby supporting different second guide wheels 318 through the plurality of second stoppers 262, so that the second circle assembly 32 or the third circle assembly 33 can be raised or lowered separately.

[0049] When placing, firstly, four stators 100 wound together with a wire are placed on the transmission assembly 316 of the first circular assembly 31 and fixed by the locking seat 3166. Then, the first tooth plate 26 rotates so that the second guide wheel 318 of the second circular assembly 32 is located on the second stop block 262, and the second guide wheels 318 of the first circular assembly 31 and the third circular assembly 33 are located on the gap between the two second stop blocks 262. At this time, only the second guide wheel 318 of the second circular assembly 32 will move with the first tooth plate 26, thereby raising the mounting block 315 of the second circular assembly 32. The first guide wheel 313 of the second circular assembly 32 is located on the first stopper 262, and the first guide wheels 313 of the first circular assembly 31 and the third circular assembly 33 are located in the sunken groove between the two first stoppers 261. At this time, the first guide wheel 313 of the second circular assembly 32 is higher than the first circular assembly 31 and the third circular assembly 33 on the first stopper 262, thereby raising the moving block 314 of the second circular assembly 32. At the same time, the moving block 314 and the mounting block 315 of the second circular assembly 32 are raised, and then the four stators 100 are placed on the transmission assembly 316 of the second circular assembly 32 and fixed by the locking seat 3166, and then reset to the same height, so as to avoid bumping into adjacent stators and wires during placement. The principle of the third circle assembly 33 is the same as that of the second circle assembly 32. At the same time, the moving block 314 and the mounting block 315 of the third circle assembly 33 are raised so that they are higher than the first circle assembly 31 and the second circle assembly 32 when placed, so as to avoid bumping into adjacent stators when placed. When assembling a circle, the second guide wheels 318 of the second circle assembly 32 and the third circle assembly 33 are both located in the gaps between the plurality of second stoppers 262 and suspended, that is, at this time, the vertical movement of the first tooth plate 26 will not drive the second guide wheel 318 to move, but will only drive the first guide wheel 313 to move vertically, thereby driving the moving blocks 314 of the first circle assembly 31, the second circle assembly 32, and the third circle assembly 33 to be raised, so that the locking seat 3166 is rotated to a vertical state through the action of the transmission assembly 316, and the plurality of stators 100 are spliced ​​into a circular winding to achieve the circle assembly action.

[0050] Compared with the prior art, the multi-layer coil assembly mechanism provided by the present invention can independently drive the second assembly assembly 32 and the third assembly assembly 33 to be raised independently through the driving mechanism 20. The first tooth plate 26 is rotatably arranged on the movable plate 24, and a plurality of first stoppers 261 of different lengths are arranged at intervals on the outer wall of the first tooth plate 26, and a plurality of second stoppers 262 of different lengths are arranged at intervals on the inner wall of the first tooth plate 26, and a through gap is formed between two adjacent second stoppers 262. One end of the first movable shaft 312 is connected to the mounting plate 311, and the other end is movably passed through the base 10 and is provided with the first guide wheel 313, and the first guide wheel 313 is fitted with the first stopper 261. One end of the second movable shaft 317 is connected to the mounting block 315, and the other end is movably passed through the base 10 and is provided with the second guide wheel 318, and the second guide wheel 318 is fitted with the second stopper 262. When the first tooth plate 26 rotates, the first guide wheel 313 of the second circle component 32 or the third circle component 33 can be controlled to be located solely on the first stop block 262, and the second guide wheel 318 can be located solely on the second stop block 262.
