The needle stand 200 can adopt a conventional needle stand with a row of needles, and is formed after being bent, so that the production cost of the motor can be further reduced.

An embodiment of the present invention further provides a manufacturing method of the motor, as shown in fig. 1 to 8, including the following steps: (1) fixing the needle holder 200 in the receiving groove 111, so that the inserting part 222 and the winding part 221 respectively extend out of the top opening and the bottom opening of the needle inserting mounting seat 110; (2) the winding portion 221 is bent obliquely upward until the winding portion 221 forms a first included angle with the axial direction of the motor (the axial direction of the motor refers to the axial direction of the motor output shaft) so as to wind a wire on the winding portion 221; (3) winding a wire on the motor frame 100, and winding a part of the wire on the winding part 221 in the winding process; (4) further bending the winding part 221 obliquely upwards until the winding part 221 forms a second included angle with the axial direction of the motor, wherein the second included angle is larger than the first included angle, so that the wire is loosened before tin immersion, the wire is prevented from being broken in the tin immersion process, the first included angle can be 30 degrees, and the second included angle can be 45 degrees; (5) placing the winding part 221 into a tin furnace for tin immersion, and wrapping the outer surface of the winding part 221 with a tin layer; (6) the extending direction of the bent insertion part 222 is parallel to the axial direction of the motor.

The cover plate 300 is fixed to the top of the pin mounting seat 110, and restricts the pin holder 200 from coming out of the receiving groove 111 from the top, so that the pin holder 200 can be stably fixed in the receiving groove 111.

Further, the width of the bottom opening of the pin mounting seat 110 may be smaller than the width of the insulating frame 210, so as to limit the pin base 200 to be separated from the bottom opening of the pin mounting seat 110, and limit the pin mounting seat 110 from the bottom, thereby further improving the stability of the pin base 200 fixed in the accommodating groove 111.

Accordingly, the method for manufacturing a motor according to the embodiment of the present invention, before the step (2), further includes a step (21): the mating part 222 is inserted through the through hole 310 of the cover plate 300 and fixes the cover plate 300 on the top of the pin mount 110.

That is, the cover plate 300 is fixed on the pin mounting base 110 by means of snap connection, and the fixing manner is simpler. Of course, the cover plate 300 may be detachably fixed on the pin mounting base 110 by other fixing methods such as screw fixation, etc. according to actual requirements.

Further, a plurality of downwardly extending support arms 340 are disposed at the bottom of the cover plate 300, and a latch 350 is disposed at the bottom end of the support arms 340. The sidewall of the pin mount 110 is provided with a guide groove 112 penetrating the pin mount 110 in the thickness direction, and the latch 350 is slidable along the guide groove 112.

As shown in fig. 3 and 5, two support arms 340 may be provided, which are respectively located at two ends of the cover plate 300 in the length direction, the latches 350 on the two support arms 340 may be oppositely disposed, and the guide grooves 112 are respectively disposed at two ends of the pin mounting base 110 in the length direction, so that the latches 350 on the two support arms 340 will be fastened at two ends of the pin mounting base 110 in the length direction, so as to enhance the stability of the latch connection.

Correspondingly, the specific process of the step (21) is as follows: the cover plate 300 is fixed on the top of the pin receptacle 110 by passing the insertion part 222 through the through hole of the cover plate 300 and aligning the latch 350 with the guide groove 112, moving the cover plate 300 along the thickness direction of the pin receptacle 110 to slide the latch 350 in the guide groove 112, and after the latch 350 slides out of the guide groove 112, the latch 350 on the arm 340 will be latched on the pin receptacle 110.

As shown in fig. 6, the wire passing direction of the wire in the wire passing groove 330 is inclined with respect to the vertical plane of the arrangement direction of the pins 220, the included angle between the wire passing direction in the wire passing groove 330 and the winding direction on the motor frame 100 is smaller than a right angle, and the bending angle at which the wire bends from the motor frame 100 to enter the wire passing groove 330 is smaller, so that the wire passing of the wire is smoother and the winding is more convenient.

Further, the width of the wire passing groove 330 is gradually reduced and then gradually increased in the routing direction, so that the width of the inlet and the outlet of the wire passing groove 330 is larger, and the wires easily enter the wire passing groove 330 and are also easily led out from the wire passing groove 330.

Correspondingly, in the manufacturing method of the motor according to the embodiment of the present invention, the step (3) specifically includes: the wire is wound on the motor frame 100, and part of the wire passes through the wire passing groove 330 in the winding process and is wound on the winding part 221 guided by the wire passing groove 330.

The header 200 includes an insulating frame 210 and a plurality of pins 220 fixed on the insulating frame 210, the pins 220 are arranged in a row, two ends of the pins 220 are respectively a plug portion 222 for plugging the connector 600 and a winding portion 221 for winding, the winding portion 221 can extend from the top opening, and the plug portion 222 can extend from the bottom opening. The insertion portion 222 may be bent to bend the insertion portion 222 above the winding portion 221, so as to form the structure shown in fig. 10. Since the winding part 221 is located at the top of the insulating bobbin 210, the conductive wire does not need to go over the insulating bobbin 210, but is directly wound on the winding part 221 at the top of the insulating bobbin 210.

The pin holder 200 of the present embodiment is separated from the pin mounting base 110, and the insulating frame 210 can be fixed in the accommodating groove 111 during the motor assembling process, and the inserting portion 222 and the winding portion 221 respectively extend out of the top opening and the bottom opening of the pin mounting base 110. Because the motor framework 100 and the needle seat 200 are split and are not integrally injection-molded, the needle seat 200 can adopt a conventional needle-arranging needle seat, thereby effectively reducing the production cost of the motor. Meanwhile, the motor of the present embodiment facilitates winding the wire on the wire winding part 221.

The foregoing is a more detailed description of the present invention that is presented in conjunction with specific embodiments, and the practice of the invention is not to be considered limited to those descriptions. It will be apparent to those skilled in the art that a number of simple derivations or substitutions can be made without departing from the inventive concept.
