DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1

[0024] Please refer to the attached Figure 1-2 , a sensor coil auxiliary winding device, comprising:

[0025] A base plate 1, an electronic winding machine 2, an auxiliary fixing frame 3, a coil skeleton 4 and a coil auxiliary guiding assembly 5, wherein the base plate 1 is provided with at least one strip-shaped mounting through hole 10, the electronic winding machine 2 and the auxiliary fixing frame 3 are detachably connected to the base plate 1 in a relative position, one end of the coil skeleton 4 is detachably connected to the electronic winding machine 2, and the other end is in contact with the auxiliary fixing frame 3, and the coil auxiliary guiding assembly 5 is movably connected to the base plate 1.

[0026] Specifically, the contact point between the auxiliary fixing frame 3 and the coil skeleton 4, the connection point between the electronic winding machine 2 and the coil skeleton 4, and the coil skeleton 4 are located at the same horizontal axis.

[0027] The coil frame 4 is fixed and clamped by the electronic winding machine 2 and the auxiliary fixing frame 3. While the electronic winding machine 2 drives the coil frame 4 to rotate, the coil auxiliary guiding assembly 5 guides the wire to make horizontal reciprocating motion, thereby achieving the purpose of tightly winding the wire around the coil frame 4.

[0028] Specifically, the coil auxiliary guide assembly 5 includes a U-shaped bracket 53, a guide roller 54, a rotating rod 55 and an arc-shaped baffle 56. The U-shaped bracket 53 is detachably connected to the base plate 1. Both ends of the guide roller 54 are respectively connected to the side walls of the U-shaped bracket 53 by bearings. The rotating rod 55 is located at the upper end of the guide roller 54, and its two ends are respectively connected to the side walls of the U-shaped bracket 53 by bearings. One end of the arc-shaped baffle 56 is fixedly connected to the curved side wall of the rotating rod 55, and the other end is in contact with the guide roller 54.

[0029] Specifically, the guide roller 54 is provided with a spiral cross guide groove 540;

[0030] Taking into account the need to produce a large number of sensors of the same specification in actual applications, in this case, there is no need to adjust the coil auxiliary guide assembly 5 multiple times. Therefore, a coil auxiliary guide assembly 5 of fixed specifications is designed. The wire is guided by fixing the guide roller 54 on the U-shaped bracket 53, and the spiral cross guide groove 540 on the guide roller 54 can make the wire reciprocate in the horizontal direction during the rotation. At the same time, through the arrangement of the rotating rod 55 and the arc-shaped baffle 56, the weight of the baffle 56 is used to ensure that the wire does not protrude from the spiral cross guide groove 540. At the same time, the tension of the wire during winding can be ensured by applying pressure to the wire.

[0031] Embodiment 2

[0032] Please refer to the attached Figure 3-4

[0033] The coil auxiliary guide assembly 5 includes a servo motor 50, a screw 500, a slider 501, a telescopic sleeve 51 and a line guide box 52. The servo motor 50 is fixedly connected to the bottom plate 1. The screw 500 is fixedly connected to the servo motor 50, and the end of the screw 500 away from the servo motor 50 passes through the slider 501 and is threadedly connected to the slider 501. The telescopic sleeve 51 is fixedly connected to the top wall of the slider 501. The line guide box 52 is fixedly connected to the top of the telescopic sleeve 51, and the telescopic sleeve 51 is provided with an adjustment bolt 510.

[0034] Taking into account the need to produce small batches of sensors of different specifications in actual applications, it is not appropriate to produce corresponding guide rollers for sensors of different specifications. In this case, the wire is guided in the horizontal direction by the provided line guide box 52, and then the screw 500 is driven to rotate by the servo motor 50. The threaded connection between the screw 500 and the slider 501 drives the slider 501 to perform a circular reciprocating motion, which indirectly drives the line guide box 52 to perform a circular reciprocating motion, thereby achieving the purpose of driving the wire to move in the horizontal direction by the servo motor 50. The setting of the telescopic sleeve 51 takes into account the different sizes of different coil skeletons 4. In order to further and better utilize the line guide box 52, the scope of application of the line guide box 52 is expanded by the telescopic sleeve 51.

[0035] Specifically, the line guide box 52 includes a box body 520, a box cover 521, a support plate 522 and at least one group of tension plates 523. The box body 520 is provided with two groups of symmetrical threading holes 5200. The box cover 521 is buckled and connected to the box body 520. The support plate 522 is fixedly connected to the middle position of the bottom wall of the box body 520 through a connecting rod 5220. At least one group of tension plates 523 is fixedly connected to the inner top wall of the box cover 521 through a telescopic rod 5230.

[0036] The wire is guided by the support plate 522 and the tensioning plate 523 provided on the box body 520 and the box cover 521, so that the wire moves in an S shape. In this process, the tension of the wire can be better maintained to avoid the situation where the wire is too tight and causes deformation or breakage during the winding process.

[0037] Specifically, the controller of the servo motor 50 is provided with a servo motor controller PLC connected thereto; the servo motor 50 serves as the power for guiding the horizontal movement of the wire, and it can control the moving distance of the reciprocating motion of the slider 501 by the frequency of switching the forward and reverse rotation of the servo motor 50. At the same time, in order to quickly and accurately adjust the servo motor 50 according to the length of the coil skeleton 4, the servo motor controller PLC is set to control the servo motor 50. It should be noted that in order to reduce the friction when the slider 501 and the base plate 1 slide relative to each other, this purpose can be achieved by installing a rotating wheel at the bottom of the slider 501.

[0038] Specifically, the base plate 1 is provided with a distance scale that matches the position of the servo motor 50 ; the distance scale is provided to facilitate the calibration of the distance of the reciprocating motion of the slider 501 when the slider 501 moves horizontally driven by the servo motor 50 .

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
