Description

Technical Field

[0001] The present invention relates to the technical field of winding devices, and particularly relates to a winding system for performing cross-wiring on the opposite side of a motor coil. Background Art

[0002] A winding machine is a machine that winds a linear object around a specific workpiece. Most electrical products require enameled copper wire (hereinafter referred to as enameled wire) to be wound into inductance coils, and thus a winding machine is needed. As is well known, a motor coil includes a coil bobbin, a plurality of winding posts arranged inside the coil bobbin, and a wire wound around the winding posts. Currently, a motor coil is wound by one wire, that is, one wire needs to be wound around a plurality of winding posts in sequence. Therefore, after winding one winding post, it is necessary to perform cross-wiring to another winding post for winding. In the prior art, cross-wiring is generally performed inside or on the top of the coil bobbin. For example, the motor armature, its winding method, and the motor disclosed in the patent number CN202011358571.4 set the wire-passing part on the end face, that is, the inside of the iron core. However, when cross-wiring is required outside the coil bobbin, since the coil bobbin is fixed by clamping devices all around, the guide pin can only be inserted into the coil bobbin from the middle and the end is extended out, so that the wire is located outside. However, the end of the guide pin is generally relatively short and needs to cross the winding post and the housing to extend out. Therefore, when the distance is not enough, the guide pin will be tilted to make the end extend out of the coil bobbin more, so that the wire is located outside, and then cross-wiring is performed. However, this is not convenient for fixing the position of the wire, and the position of cross-wiring during movement cannot be guaranteed. Moreover, when the specification of the coil bobbin is small, the inner hole diameter is very small, which will result in insufficient space to tilt the guide pin. To sum up, there is no winding device in the prior art that can be applied to cross-wiring outside the coil bobbin. Summary of the Invention

[0003] In view of this, the present invention provides a winding system for performing cross-wiring on the opposite side of a motor coil to solve the above technical problems.

[0004] A winding system for cross-wiring on the opposite side of a motor coil. The winding system for cross-wiring on the opposite side of a motor coil also requires a guide pin and a wire output from the guide pin during cross-wiring. The winding system for cross-wiring on the opposite side of a motor coil includes a coil bobbin and a cross-wiring loop disposed below the coil bobbin. The coil bobbin includes a cylindrical outer housing, a plurality of winding posts spaced apart inside the outer housing, and a plurality of lower limit plates disposed at the lower end of the outer housing. The cross-wiring loop is cylindrical, one end of the cross-wiring loop close to the coil bobbin is rounded, and an avoidance groove with an opening facing the coil bobbin is provided on the cross-wiring loop. The inner diameter of the cross-wiring loop is greater than the diameter of the circle formed by the plurality of lower limit plates and less than the outer diameter of the outer housing. During cross-wiring, the guide pin is located in the avoidance groove, so that the wire is abutted between the outer housing and the rounded end of the cross-wiring loop to limit the position of the wire, and the coil bobbin is rotated to make the wire disposed around the lower limit plates.

[0005] Further, the winding system for cross-wiring on the opposite side of a motor coil further includes a bracket and three locking components disposed on the bracket.

[0006] Further, the bracket includes a base and a locking ring disposed on the base. The base is cylindrical, three connecting grooves and three mounting grooves are circumferentially spaced on the outer side wall of the base. The connecting grooves are located between the mounting grooves and the locking ring. The locking ring is cylindrical and its inner diameter is smaller than the inner diameter of the base. Three rectangular through holes are circumferentially spaced on the outer side wall of the locking ring.

[0007] Further, the locking component includes a U-shaped bracket disposed on the connecting groove, a rotating rod rotatably disposed on the U-shaped bracket, a spring disposed at one end of the rotating rod, and a locking block disposed at the other end of the rotating rod. The middle position of the rotating rod is rotatably connected to the U-shaped bracket through a rotating shaft. One end of the spring is connected to the mounting groove and the other end is connected to one end of the rotating rod. The locking block is inserted into the rectangular through hole and the end facing the coil bobbin is in the shape of an arc groove.

[0008] Further, the coil bobbin further includes a plurality of upper limit plates disposed at the upper end of the outer housing and a plurality of support plates located between the lower limit plates.

[0009] Further, the lengths of the upper and lower limit plates are equal to the distance between two adjacent winding posts.

[0010] Further, the number of the upper and lower limit plates is half of the number of the winding posts.

[0011] Further, the support plate is located between two adjacent lower limit plates.

[0012] Further, guiding portions are provided at both ends of the lower limit plate, and the guiding portions are connected to the arc surface of the lower limit plate.

[0013] Compared with the prior art, the upper limit plate and the lower limit plate are respectively arranged at the upper and lower ends of the coil bobbin of the winding system for cross-wiring on the opposite side of the motor coil provided by the present invention. One end of the cross-wiring loop close to the coil bobbin is provided with a rounded corner, and an avoidance groove with an opening facing the coil bobbin is provided. The inner diameter of the cross-wiring loop is larger than the diameter of the circle formed by a plurality of the lower limit plates and smaller than the outer diameter of the outer shell. When cross-wiring, by moving the cross-wiring loop upward, the guide pin is located in the avoidance groove, and the wire can be abutted between the outer shell and the cross-wiring loop, so as to fix the position of the wire. It is not necessary to skew the wire, and the position of the wire can be fixed better, ensuring that the wire can be attached to the lower limit plate. Finally, rotate the bracket and the coil bobbin so that the wire is arranged around the lower limit plate. When rotated to the specified position, the cross-wiring loop moves downward so that the wire is attached to the lower limit plate. The guide pin resets back into the coil bobbin to tighten the wire and starts winding the wire around another winding post to complete the cross-wiring. Description of the Drawings

[0021] The following further details the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0022] As Figures 1 to 7 shown, it is a schematic structural view of the winding system provided by the present invention for making a jumper on the opposite side of the motor coil. The winding system for making a jumper on the opposite side of the motor coil includes a bracket 10, three locking components 20 arranged on the bracket 10, a bobbin 30 arranged on the bracket 10, and a jumper loop 40 arranged below the bobbin 30. It can be conceived that the winding system for making a jumper on the opposite side of the motor coil further includes some other functional modules, such as a rotating component, a three-axis moving component, and a guide pin, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein.

[0023] The bracket 10 includes a base 11 and a locking ring 12 arranged on the base 11.

[0024] The base 11 is cylindrical and is arranged on an external rotating device and is driven by it to rotate, so that the winding system for making a jumper on the opposite side of the motor coil rotates during winding and making a jumper. Three connecting grooves 13 and three mounting grooves 14 are circumferentially spaced on the outer side wall of the base 11. The connecting grooves 13 and the mounting grooves 14 are used to arrange the locking components 20. The connecting grooves 13 are located between the mounting grooves 14 and the locking ring 12. The locking ring 12 is cylindrical and its inner diameter is smaller than the inner diameter of the base 11 to leave a space for the jumper action of the jumper loop 40 and the guide pin. Three rectangular through holes 121 are circumferentially spaced on the outer side wall of the locking ring 12, and the rectangular through holes 121 are used to pass through the locking components 20.

[0025] The locking component 20 includes a U-shaped bracket 21 arranged on the connecting groove 13, a rotating rod 22 rotatably arranged on the U-shaped bracket 21, a spring 23 arranged at one end of the rotating rod 22, and a locking block 24 arranged at the other end of the rotating rod 22.

[0026] The middle position of the rotating rod 22 is rotatably connected to the U-shaped bracket 21 through a rotating shaft. One end of the spring 23 is connected to the installation groove 14, and the other end is connected to one end of the rotating rod 22. The locking block 24 is inserted into the rectangular through hole 121, and the end facing the coil bobbin 30 is in the shape of an arc groove, so as to better abut against the arc side wall of the coil bobbin 30. The elastic force of the spring 23 always abuts against one end of the rotating rod 22, so that the rotating rod 22 rotates and the locking block 24 on the other end is inserted into the rectangular through hole 121, and then abuts against the coil bobbin 30 in the locking ring 12 to achieve locking.

[0027] The coil bobbin 30 includes a cylindrical outer shell 31, a plurality of winding posts 32 spaced inside the outer shell 31, a plurality of upper limit plates 33 provided at the upper end of the outer shell 31, a plurality of lower limit plates 34 provided at the lower end of the outer shell 31, and a plurality of support plates 35 located between the lower limit plates 34.

[0028] The outer shell 31 is arranged in the locking ring 12 and fixed by a plurality of the locking components 20. The winding posts 32 are used for winding wires. The structures of the outer shell 31 and the winding posts 32 should be prior art and will not be elaborated here.

[0029] The upper and lower limit plates 33 and 34 are respectively used to set the wires of the upper and lower cross wires. The lengths of the upper and lower limit plates 33 and 34 are equal to the distance between two adjacent winding columns 32, so that after winding one winding column 32, crossing one limit plate can reach another winding column 32. The number of the upper and lower limit plates 33 and 34 is half of the number of the winding columns 32. In this embodiment, the number of the winding columns 32 is 6, and every two winding columns 32 form a group. There are three upper and lower limit plates 33 and 34 respectively. The upper limit plate 33 is used for cross wiring between two adjacent winding columns 32, and the lower limit plate 34 is used for cross wiring between adjacent groups of winding columns 32, that is, after winding one winding column 32, cross wiring through the upper limit plate 33 to the adjacent winding column 32 for winding. After winding again, cross wiring through the lower limit plate 34 to another group of winding columns 32 for winding, and cycle in this way to complete the winding of all winding columns 32. It can be imagined that the cross wiring direction, cross wiring distance, etc. can be changed according to different coil skeletons, and will not be elaborated here again. Since the cross wiring distance of the lower limit plate 34 is relatively long, the wires between two adjacent lower limit plates 34 are supported by the support plate 35 to ensure that the wires will not move. The two ends of the lower limit plate 34 are provided with guiding parts 37, and the guiding parts 37 are connected to the arc surface of the lower limit plate 34 and are used to facilitate the introduction of the wire into the lower limit plate 34 after cross wiring.

[0030] The cross wiring ring 40 is in a cylindrical shape. One end of the cross wiring ring 40 away from the coil skeleton 20 is closed, so as to be connected with an external rotating and moving device, and the cross wiring ring 40 is driven to rotate and move up and down by the external rotating and moving device. One end of the cross wiring ring 40 close to the coil skeleton 20 is provided with a rounded corner. This end is used to cooperate with the outer shell 31 to press against the wire during cross wiring. The rounded corner setting can avoid damaging the wire and can better clamp the wire with a circular cross section with the outer shell 31. An avoidance groove 41 with an opening facing the coil skeleton 20 is arranged on the cross wiring ring 40, and the avoidance groove 41 is used to avoid the protruding winding guide needle. The inner diameter of the cross wiring ring 40 is larger than the diameter of the circle formed by a plurality of lower limit plates 34 and smaller than the outer diameter of the outer shell 31, so that the cross wiring ring 40 is located outside the lower limit plates 34.

[0031] First, wind the wire around one of the winding posts 32 through a guide pin, and then perform cross-wiring. The guide pin is L-shaped to facilitate insertion into the two winding posts 32 and also to facilitate the guide pin to extend out of the coil bobbin 30 for cross-wiring on the outside. The guide pin should be prior art and will not be elaborated here. During cross-wiring, first let the guide pin extend out of the coil bobbin 20 from one end of the lower limit plate 34 and rotate a certain angle so that the wire is in close contact with one end of the lower limit plate 34. Then rotate the cross-wiring ring 40 by a certain angle so that the avoidance groove 41 corresponds to the position of the guide pin. Move the cross-wiring ring 40 upward so that the guide pin can be located in the avoidance groove 41 and the wire is pressed between the outer housing 31 and the rounded end of the cross-wiring ring 40. At this time, the distance between the outer housing 31 and the cross-wiring ring 40 is less than the diameter of the wire, thus restricting the position of the wire. Finally, rotate the bracket 10 and the coil bobbin 20. Since the guide pin remains stationary, the rotation of the coil bobbin 20 will continuously pull out the wire and cause the wire to be arranged around the lower limit plate 34. Stop when rotating to the other end of the lower limit plate 34. Move the cross-wiring ring 40 downward so that the wire is in contact with the lower limit plate 34. The guide pin resets back into the coil bobbin to tighten the wire and starts winding the wire around another winding post 32. For the upper limit plate 33, directly extend the wire out of the coil bobbin for cross-wiring, which will not be elaborated here.

[0032] Compared with the prior art, the upper and lower ends of the coil bobbin 30 of the winding system for cross-wiring on the opposite side of the motor coil provided by the present invention are respectively provided with the upper limit plate 33 and the lower limit plate 34. One end of the cross-wiring ring 40 close to the coil bobbin 20 is rounded and provided with an avoidance groove 41 with an opening facing the coil bobbin 20. The inner diameter of the cross-wiring ring 40 is greater than the diameter of the circle formed by the multiple lower limit plates 34 and less than the outer diameter of the outer housing 31. During cross-wiring, by moving the cross-wiring ring 40 upward, the guide pin is located in the avoidance groove 41 and the wire can be pressed between the outer housing 31 and the cross-wiring ring 40, thereby fixing the position of the wire. There is no need to skew the wire, and the position of the wire can be better fixed, ensuring that the wire can be in contact with the lower limit plate 34. Finally, rotate the bracket 10 and the coil bobbin 20 to arrange the wire around the lower limit plate 34. When rotating to the specified position, move the cross-wiring ring 40 downward so that the wire is in contact with the lower limit plate 34. The guide pin resets back into the coil bobbin to tighten the wire and starts winding the wire around another winding post 32 to complete cross-wiring.

[0033] The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are all covered within the scope of the claims of the present invention.
