In the prior art, when performing lifting movements in a narrow space, a servo + screw structure is generally used. This structure cannot be used in many places due to its large size, and the accuracy is relatively low, and the stability cannot meet the use requirements. That is, the overall structure of the existing Z-axis motor is large in size, low in accuracy, and complex in structure and difficult to install. Utility Model Content

[0014] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model is further described in detail below in conjunction with the drawings and specific embodiments.

[0015] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0016] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0017] Please refer to Figure 1-2 The novel Z-axis motor of the embodiment of the utility model includes a housing, a stator, a PCB control board, a magnet, a slide rail and two sliders mounted on the slide rail.

[0018] Two sliders are respectively arranged at the upper and lower ends of the housing. The slide rail is connected to the magnet. The stator is correspondingly installed in the housing. The magnet of the utility model is fixed on the slide rail, and the slide rail is driven to move up and down by the magnet. The slider is fixed on the housing of the motor, and the slider is fixed. The structure of the utility model can make the volume smaller.

[0019] A column is arranged on the top of the housing, a PCB control board is arranged on the column, and the stator is electrically connected to the PCB board. In specific implementation, a power line can be used, the power line extends from the top of the housing, and the power line is welded to the top PCB control board after extending.

[0020] The upper and lower ends of the slide rail are respectively provided with an upper limit block for limiting the downward movement of the slide rail and a lower limit block for limiting the upward movement of the slide rail. That is, the upper limit block and the lower limit block correspond to the upper end and the lower end of the shell, respectively, and the upper limit block and the lower limit block are respectively arranged at the lower limit position and the upper limit position of the movement stroke of the slide rail. The upper limit block and the lower limit block of the utility model can also be used as parts connected to the outside.

[0021] As an embodiment, the housing is composed of a U-shaped housing and a cover plate, the cross section of the U-shaped housing is U-shaped, the stator is arranged on one side of the U-shaped housing, the slider is correspondingly arranged on the other side (i.e., the opposite side) of the U-shaped housing, and the magnet is located between the slider and the stator. The utility model can effectively improve the accuracy of each part and reduce the number of disassembled parts.

[0022] As an implementation method, the new Z-axis motor also includes a grating ruler and a corresponding encoder. The grating ruler is arranged on the middle section of the slide rail, and the encoder is correspondingly arranged on the other side of the U-shaped housing. The grating ruler of the utility model is installed on the slide rail in the middle section of the two sliders, and moves up and down with the slide rail. When the motor moves up and down, the stroke is limited by the upper and lower limit blocks, and at the same time, it is ensured that the grating ruler will not collide with the slider. The encoder line reaches the top through the wire groove on the U-shaped housing, and then the encoder line position is limited by an encoder line fixing plate, and finally the encoder line is welded to the top PCB control board.

[0023] As an implementation manner, there are multiple columns, and the multiple columns are arranged on the top of the U-shaped shell.

[0024] As an implementation method, the length of the magnet is less than or equal to the length of the slide rail and greater than the length of the stator (ie, the length in the Z-axis direction).

[0025] The power line and encoder line are uniformly welded to a PCB control board, and then output to the outside through a unified interface on the PCB control board. The PCB control board is supported by a column, which can effectively reduce the scratching of the motor line during the operation of the Z-axis.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
