[0023] To more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following describes specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the drawings described below are merely examples of the present invention. A person skilled in the art can, without inventive effort, derive other drawings and other embodiments from these drawings. Furthermore, design orientations only represent relative positional relationships between components, not absolute positional relationships.
[0024] The present invention provides an integrated motor. Figure 1 、 Figure 2 、 Figure 3 It mainly includes a motor body 1 and a main control body 2 fixed at the rear end of the motor body 1. The tail end of the rotating shaft of the motor body 1 is provided with an encoder magnet 3 that rotates synchronously with the rotating shaft. The main control body 2 is provided with an encoder chip 4 corresponding to the encoder magnet 3.
[0025] The main control body 2 is mainly composed of the control circuit board of the yarn feeder, that is, the main control board 22. The main control body 2 includes a bottom shell 21 fixedly connected to the motor body 1, a main control board 22 and a protective shell 23, wherein the bottom shell 21 is fixedly connected to the rear end of the motor body 1 and can be fixedly connected based on the rear end shell of the motor body 1, but it is necessary to lead out the rotating shaft of the motor body 1 and load the encoder magnet 3 on it so that it corresponds to the encoder chip 4 on the main control board 22, so that the main control board 22 can obtain the rotation data of the motor body 1.
[0026] In a specific embodiment, an encoder chip 4 is disposed on the front side of the main control board 22 facing the bottom housing 21, corresponding to the through-hole, so that the encoder chip 4 is close to the encoder magnet 3 within the through-hole. The encoder magnet and the encoder chip are disposed in close proximity, with a spacing preferably between 0.2 mm and 2 mm. This spacing can be adjusted based on actual accuracy requirements, or anti-interference measures can be implemented. In this application, the technical solution is described based on meeting the most basic usage requirements.
[0027] In an embodiment of the present application, a bottom shell 21 can be provided at the rear end of the motor body 1, and the main control board 22 can be fixedly installed on the bottom shell 21, and then a protective shell 23 is provided to be buckled onto the back of the main control board 22, that is, the protective shell 23 buckles the main control board 22 onto the bottom shell 21 to form the main control body 2.
[0028] In a specific embodiment, the bottom shell 21 includes a connecting portion and an extending portion. A through hole is provided at the center of the connecting portion for accommodating the encoder magnet 3. The tail of the rotating shaft of the motor body 1 is placed in the through hole. The extending portion extends downward perpendicular to the motor body 1.
[0029] The bottom shell 21 can be considered to be composed of two parts: a connecting portion and an extension portion. The connecting portion is circular and coaxial with the motor body 1. The extension portion connects to the lower half of the connecting portion and extends downward for a certain length. Of course, the connecting portion and the extension portion can be designed as an integrated unit, and based on the location of the through hole, they can be coaxially assembled and fixed to the rotating shaft of the motor body 1.
[0030] It is understood that the width of the extension portion is the same as the maximum width or diameter of the connection, and the extension portion extends downward from the maximum width of the connection portion, such as Figure 2 As shown in .
[0031] In a specific embodiment, the downward extension length of the extension portion may be less than the length of the protective shell 23, that is, the overall length of the bottom shell 21 is less than the length of the protective shell 23, so that the lower part of the front of the main control board 22 is exposed, and this area can be set as an external control area.
[0032] The electrical connection between the main control board 22 and the motor body 1 can be achieved by using leads. The motor body 1 can lead out the connecting wires from the rear end and directly weld them on the main control board 22 to achieve control of the motor body 1. In this process, the leads need to pass through the bottom shell 21.
[0033] As a feasible embodiment, since the bottom shell 21 has a through hole for accommodating the encoder magnet 3, the leads can also pass through the through hole and electrically connect to the main control board 22. However, this approach may affect the spacing between the encoder chip 4 and the encoder magnet 3, or directly cause interference. The size of the through hole and the relative position of the chip and magnet can be adaptively adjusted to address these shortcomings and completely eliminate or reduce these interferences.
[0034] In a preferred embodiment, the outer edge of the bottom shell 21 is provided with long or arc-shaped holes, through which the wiring of the motor body 1 is electrically connected to the main control board 22. The holes are far away from the location of the magnets, which can effectively reduce the possibility of interference.
[0035] For example, the cable may be a needle structure or a wire, which is led out from the rear end of the motor body 1 to the area where the main control board 22 is located, and the cable is welded to the corresponding interface of the main control board 22.
[0036] In the embodiment of the present application, the motor body 1 and the main control body 2 can be directly transported as finished products after being fixed and assembled, without the need for classified transportation, which can effectively reduce the overall transportation protection cost, especially for the transportation of circuit boards.
[0037] In the present application, for the fixed assembly form of the motor body 1 and the main control body 2, an outer shell can also be provided for overall protection, and external control keys, buttons, etc. can be constructed based on the outer shell to achieve basic starting control.
[0038] In a specific embodiment, the motor body 1 and the main control body 2 are fixedly assembled and then installed in an outer shell; an operating port is opened at the front end of the outer shell, and the operating end 13 of the motor body 1 is exposed through the operating port.
[0039] For example, the outer shell includes a fixed shell 12 and an outer shell 11. The motor body 1 and the main control body 2 are assembled in the fixed shell 12. The outer shell 11 is buckled on the fixed shell 12, and the working end 13 of the motor body 1 is exposed outside the outer shell 11 and the fixed shell 12. A connecting base plate is provided at the bottom of the fixed shell 12, and the outer shell 11 is sleeved on the connecting base plate. The connecting base plate is used to fix the fixed shell 12 on the working platform. The working port can be opened at the front end of the fixed shell 12 and the outer shell 11, such as Figure 1 As shown in .
[0040] In the outer shell, Figure 1 As shown in the figure, the motor body 1 is horizontally arranged within the fixed shell 12 and the outer shell 11, and the main control body 2 is vertically arranged within the fixed shell 12 and the outer shell 11. Of course, other layouts are also possible and can be adjusted according to the installation requirements of the work platform, such as the motor body 1 and the main control body 2 being fixed in a straight line; or the motor body 1 and the main control body 2 being fixed at a certain angle, such as 90°, 120°, etc.
[0041] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
