[0018] The following is a further detailed description of the specific embodiments of the present invention. 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.

[0019] like Figure 1 As shown, it is a schematic diagram of the structure of the wire flattening mechanism of the motor coil provided by the utility model. The wire flattening mechanism of the motor coil includes a machine 10, a turntable device 20 arranged on the machine 10, an unlocking device 30 arranged on one side of the turntable device 20, and a wire pressing device 40 arranged on one side of the turntable device 20. It can be imagined that the wire flattening mechanism of the motor coil also includes some other functional modules, such as a power module, a feeding module, etc., which are technologies well known to those skilled in the art and will not be described one by one here.

[0020] Please also read Figures 2 to 5 It should be noted that the wire flattening mechanism of the motor coil is used to perform wire flattening operation on a motor coil 50, and the motor coil 50 includes two coil skeletons 51 and a section of wire 52 wound on the two coil skeletons 51. The wire flattening mechanism of the motor coil needs to fix the motor coil 50 on the turntable device 20, and perform wire flattening operation on the wire 52 connected between the two coil skeletons 51, so that the section of wire 52 is flat and regular.

[0021] The machine platform 10 is used to carry various devices and enable them to cooperate with each other to complete various operations on the motor coil 50 .

[0022] The turntable device 20 includes a turntable 21 and at least four carrier plates 22 spaced apart from each other at the edge of the turntable 21 .

[0023] The turntable 21 is driven to rotate by a rotary motor disposed inside the machine 10 .

[0024] At least four accommodating chambers 23 are provided on the carrier 22. A pull rod 24 is movably provided on one side of the accommodating chamber 23 away from the center of the rotating disk 21. A clamping block 25 is provided at one end of the pull rod 24 located in the accommodating chamber 23. A spring 26 is sleeved on the pull rod 24. One end of the spring 26 abuts against the clamping block 25, and the other end abuts against the inner wall of the accommodating chamber 23. The pull rod 24 is pulled in this way to increase the volume inside the accommodating chamber 23. After the coil skeleton 51 is placed in the accommodating chamber 23, the pull rod 24 is released, and the coil skeleton 51 is clamped and fixed by the elastic potential energy of the spring 26.

[0025] A chuck 27 is provided on one side of the pull rod 24 away from the accommodating chamber 23. The inner side of the chuck 27 has an inclined surface. The chuck 27 is used to cooperate with the unlocking device 30 to unlock the pull rod 24 to release the coil skeleton 51 and facilitate the placement of the coil skeleton 51. The specific cooperation between the chuck 27 and the unlocking device 30 will be described below.

[0026] Two of the accommodating chambers 23 form a group, and two of the coil skeletons 51 are placed therein, so as to clamp and position a motor coil 50. A wire groove 28 is respectively provided on the opposite side of the two accommodating chambers 23, and the wire groove 28 is used to pass the wire 52 to locate the two ends of the wire 52.

[0027] The unlocking device 30 includes at least two lifting cylinders 31 spaced apart from each other on the circumference of the turntable 21 , and at least two unlocking plates 32 respectively disposed at output ends of the two lifting cylinders 31 .

[0028] The output direction of the lifting cylinder 31 is toward the chuck 27, and the end surface of the unlocking plate 32 is provided with at least four slots 33 corresponding to the chuck 27. The end of the unlocking plate 32 has an inclined surface, and the inclined surface on the unlocking plate 32 corresponds to the inclined surface on the chuck 27, so that the unlocking plate 32 is lifted under the drive of the lifting cylinder 31, and the unlocking plate 32 will push the chuck 27 in the direction away from the turntable device 20, thereby driving the pull rod 24 and compressing the spring 26 to unlock the accommodating chamber 23 and release the coil skeleton 51.

[0029] The wire pressing device 40 includes at least one ascending cylinder 41, at least one support plate 42 arranged at the output end of the ascending cylinder 41, at least two forward cylinders 43 arranged on the support plate 42 at intervals, at least two top plates 44 respectively arranged at the output ends of the two forward cylinders 43, at least two downward pressing cylinders 45 respectively arranged on the two top plates 44, and two pressing plates 46 respectively arranged at the output ends of the two downward pressing cylinders 45.

[0030] The output direction of the rising cylinder 41 is perpendicular to the machine 10, and the output direction of the forward cylinder 43 is toward the turntable device 20. The top plate 44 can move under the drive of the rising cylinder 41 and the forward cylinder 43, so that the top plate 44 and the pressing plate 46 are sent to the pressing line position.

[0031] A top block 47 is disposed at one end of the top plate 44 facing the turntable device 20 , and an end of the top block 47 has an inclined surface, so that the top block 47 can be easily inserted between the wire 52 and the carrier 22 .

[0032] The output direction of the downward pressing cylinder 45 is toward the top block 47, and the pressing plate 46 is provided with a pressing block 48 protruding toward the end surface of the top plate 44, and the pressing block 48 corresponds to the top block 47. In this way, after the top plate 44 and the pressing plate 46 enter the wire pressing position, the wire 52 is located between the top block 47 and the pressing block 48. The downward pressing cylinder 45 drives the pressing plate 46 to press downward, so that the wire 52 is pressed between the top block 47 and the pressing block 48, thereby completing the wire pressing operation.

[0033] The wire flattening mechanism of the motor coil also includes at least two fixing devices 60 arranged at intervals on one side of the turntable device 20, and the fixing device 60 has a fixing cylinder 61. A concave block 62 is arranged at the output end of the fixing cylinder 61, and at least four protrusions 63 matching the concave block 62 are arranged at the edge of the mounting plate 21. The fixing cylinder 61 drives the concave block 62 to be clamped on the protrusion 63 to fix the mounting plate 21, thereby preventing the rotating plate 21 from rotating or shaking, and improving the production quality.

[0034] Compared with the prior art, the wire flattening mechanism of the motor coil provided by the utility model completes the clamping and releasing of the coil skeleton 51 through the cooperation of the unlocking plate 32 and the chuck 27, so as to facilitate the taking and placing of the motor coil 50 and the subsequent wire pressing operation. The driving of the rising cylinder 41 and the forward cylinder 43 sends the top plate 44 and the pressing plate 46 to the wire pressing position, and the pressing cylinder 45 drives the pressing plate 46 to press down, so that the wire 52 is pressed between the top block 47 and the pressing block 48, thereby completing the wire pressing operation. The wire flattening mechanism of the motor coil does not require manual operation throughout the process, has a high degree of automation, and is suitable for assembly line production operations.

[0035] 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 are included in the scope of the claims of the present invention.
