Referring to fig. 1 to 2, an embodiment of the present invention provides a linear motor 100, including a slider 10 and a motor main body 20 disposed on a moving path of the slider 10. The slider 10 is provided with a mover 11, and the motor main body 20 is provided with a plurality of stators 21. The slider 10 is moved on the motor main body 20 by an interaction force between the mover 11 and the stator 21. The motor main body 20 is further provided with a guide rail 22. The guide rail 22 extends in the same direction as the moving path of the slider 10. The slider 10 is slidably disposed on the guide rail 22. A projection of the guide rail 22 in a horizontal direction perpendicular to an extending direction of the guide rail 22 partially overlaps a projection of the stator 21 in the horizontal direction. The motor main body 20 is further provided with a position sensor 26, and the position sensor 26 is used for detecting the position of the slider 10. Depending on the detected position of the slider 10, the slider 10 can be stopped or continued to move by controlling the state of power applied to the stator 21.

In the linear motor 100, the projection of the guide rail 22 in the horizontal direction perpendicular to the extending direction of the guide rail 22 partially overlaps the projection of the stator 21 in the horizontal direction. When the mutual force is generated between the stator 21 and the mover 11 to move the slider 10 on the guide rail 22, the direction of the mutual force directly passes through the guide rail 22, so that the slider 10 can smoothly move on the guide rail 22, thereby preventing the problem that the slider 10 of the linear motor 100 is inclined to affect the connection stability between the slider 10 and the guide rail 22.

In the present embodiment, for convenience of description, the extending direction of the guide rail 22 is denoted as the X direction, the horizontal direction perpendicular to the extending direction of the guide rail 22 is denoted as the Y direction, and the vertical direction perpendicular to the extending direction of the guide rail 22 is denoted as the Z direction. During the operation of the linear motor 100, the slider 10 may slide on the guide rail 22 by generating an interaction force between the mover 11 and the stator 21. Specifically, the mover 11 is a permanent magnet, and the stator 21 is an electromagnet. When the stator 21 is energized, an interaction force is generated between the electromagnet and the permanent magnet, so that the slider 10 can slide on the guide rail 22. It is to be understood that the stator 21 may be a permanent magnet and the mover 11 may be an electromagnet, as long as the generation of the interaction force between the mover 11 and the stator 21 is achieved.

Referring to fig. 3, the motor main body 20 includes a top surface 23 and a first side surface 24 extending downward from the top surface 23, and the stator 21 is fixed on the first side surface 24 of the motor main body 20. The top surface 23 of the motor main body portion 20 is provided with a recessed portion 25. The recessed portion 25 and the first side surface 24 are respectively disposed on both sides of the top surface 23, and the guide rail 22 is disposed on the recessed portion 25. Specifically, the bottom surface of the recessed portion 25 is further provided with a step portion 26, and the guide rail 22 is disposed next to the step portion 26 to facilitate alignment and installation of the guide rail 22. In this embodiment, the guide rail 22 is fixed to the motor main body 20 by screws. The top surface of the guide rail 22 is provided with a plurality of screw mounting holes 221. During installation, the guide rail 22 is first placed against the step 26 and then the guide rail 22 is moved in the X direction until one of the screw mounting holes 221 in the guide rail 22 is aligned with one of the screw mounting holes in the recess 25. At this time, the guide rail 22 and the motor main body 20 may be fixed by screws.

Referring to fig. 4 to 5, the sliding member 10 further includes a bearing plate 12, a slider 13 disposed on a bottom surface of the bearing plate 12, and a mover mounting plate 14 extending downward from a side surface of the bearing plate 12. The slider 13 is fitted to the guide rail 22 and is slidable in the extending direction of the guide rail 22. The mover 11 is disposed on the mover mounting plate 14. In the present embodiment, the mover 11 includes a plurality of permanent magnets 111. The permanent magnet 111 is provided on the mover attachment plate 14 on a side facing the motor main body 20, and the permanent magnet 111 and the stator 21 are provided to face each other. The permanent magnets 111 are arranged in a line in the extending direction of the guide rail 22 and spaced from each other. The magnetic pole of each permanent magnet 111 facing the stator 21 is opposite to the magnetic pole of the adjacent permanent magnet 111 facing the stator 21. That is, the N pole of the permanent magnet 111 and the S pole of the permanent magnet 111 are alternately provided at intervals along the extending direction of the guide rail 22. In this embodiment, the permanent magnet 111 has an elongated shape, and the extending direction of the body of the permanent magnet 111 is the Z direction. During assembly, the permanent magnet 111 may be embedded in the mover mounting plate 14 or fixed to the mover mounting plate 14 by glue.

Referring to fig. 2 and 5, the plurality of stators 21 are arranged at intervals along the extending direction of the guide rail 22. The stator 21 includes a plurality of exciting electromagnets 211. The plurality of excitation electromagnets 211 are aligned in a row along the extending direction (X direction) of the guide rail 22. Each exciting electromagnet 211 includes a magnetic core 212 and an exciting coil 213 wound around the magnetic core 212. A projection of the guide rail 22 in a horizontal direction (Y direction) perpendicular to an extending direction of the guide rail 22 partially overlaps a projection of the excitation coil 213 in the horizontal direction. Since the interaction force between the mover 11 and the stator 21 is mainly generated by the magnetic force between the exciting electromagnet 211 and the permanent magnet 111, by partially overlapping the projection of the guide rail 22 in the Y direction with the projection of the exciting coil 213 in the Y direction, the interaction force between the stator 21 and the mover 11 can more accurately pass through the guide rail 22, thereby achieving the effect of smoothing the operation of the slider 10. The motor main body 20 further includes a cover plate 214, as required. The cover plate 214 is disposed on the first side 24 of the motor main body 20 to prevent the stator 21 from being exposed to the external environment.

As required, a projection of the guide rail 22 in a horizontal direction (Y direction) perpendicular to the extending direction of the guide rail 22 is located within a projection of the excitation coil 213 in the horizontal direction. That is, the height of the highest point of the guide rail 22 in the Z direction is smaller than the height of the highest point of the exciting coil 213 in the Z direction; the height of the lowest point of the guide rail 22 in the Z direction is greater than the height of the lowest point of the exciting coil 213 in the Z direction. The above arrangement enables the interaction force between the mover 11 and the stator 21 to more effectively pass through the guide 22, so that the slider 10 can be more smoothly disposed on the guide 22.

Referring to fig. 5, in actual operation, the magnetic poles of the exciting electromagnet 211 are changed according to the power supply state of the exciting coil 213. The exciting coil 213 is supplied with a current of any one of the U-phase, V-phase, and W-phase in the three-phase power supply circuit. When the exciting coil 213 is energized, the magnetic pole of the exciting electromagnet 211 changes between the N pole and the S pole due to the change of the supply current. At this time, due to the interaction between the magnetic field generated by the exciting electromagnet 211 and the magnetic field generated by the permanent magnet 111, an attractive force or a repulsive force is generated between the exciting electromagnet 211 of the stator 21 and the permanent magnet 111 of the mover 11, thereby moving the slider 10 on the guide rail 22. For example, applying a current to the U-phase causes the excitation coil 213 of the U-phase to generate an N-pole at one end adjacent to the electromagnet 111; applying a current to the V-phase to make the V-phase excitation coil 213 generate an S-pole at one end adjacent to the electromagnet 111; applying a current to the W phase causes the excitation coil 213 of the W phase to generate an N pole at one end adjacent to the electromagnet 111. At this time, the U-phase exciting coil 213 generates a repulsive force with respect to the permanent magnet 111 facing the front surface thereof; the V-phase exciting coil 213 generates a repulsive force with respect to the permanent magnet 111 opposed to the front face thereof and an attractive force with respect to the adjacent permanent magnet 111; the exciting coil 213 of the W phase generates a repulsive force with respect to the permanent magnet 111 facing the front surface thereof and an attractive force with respect to the adjacent permanent magnet 111. The general force may cause the permanent magnet 111 to move in the X direction. When the permanent magnet 111 moves to the next position, the current values applied to the U-phase, V-phase, and W-phase may be changed to move the permanent magnet 111 again. It can be seen that moving the slider 10 at a prescribed speed in the extending direction of the guide rail 22 can be achieved by changing the power supply state of the exciting coil 213.

Referring also to fig. 6, the guide rail 22 includes a bottom surface 222, a top surface 223, and two side surfaces 224 connected between the bottom surface 222 and the top surface 223. The screw mounting hole 221 penetrates the top surface 223 and the bottom surface 222 to fix the guide rail 22 to the motor main body portion 20. The two sides 224 are substantially identical in shape and are symmetrical along a center line. The side surface 224 is formed with a slide groove 225. The sliding groove 225 extends in the same direction as the guide rail 22. The cross-sectional shape of the sliding groove 225 is substantially an inverted trapezoid shape, and the width of the opening thereof is gradually increased from the inside to the outside. The sliding groove 225 includes upper and lower side surfaces. The upper side of the sliding groove 225 is provided with a first arc-shaped recess 226. The first arc-shaped recess 226 extends in the X-direction. The junction of the side surface 224 and the top surface 223 is further provided with a first transition surface 227. The first transition surface 227 extends obliquely upward from the side surface 224 to the top surface 223. The first transition surface 227, the side surface 224 and the upper side surface of the sliding groove 225 together form a convex shape. The first transition surface 227 is provided with a second arc-shaped recess 228.

Referring to fig. 7, the slider 13 is provided with a concave portion 131, and the concave portion 131 is formed by extending upward from a bottom surface 132 of the slider 13. The recess 131 is used to cover the upper end of the guide rail 22. The recess 131 includes a top surface 133 and two side surfaces 134 connecting the top surface 133 of the recess 131 with the bottom surface 132 of the slider 13. The two sides 134 are substantially identical in shape and are symmetrical along a center line. The side surface 134 is formed with a protrusion 135 at a position close to the bottom surface 132. The projection 135 is adapted to be fitted into the slide groove 225 of the guide rail 22 to prevent the slider 13 from being displaced in the Z direction. In the present embodiment, the bump 135 is substantially trapezoidal, and the width of the bump 135 is gradually decreased from the side 134 toward the inside. The upper surface of the projection 135 is provided with a first arc-shaped protrusion 136. When the slider 13 is assembled to the guide rail 22, the first arc-shaped protrusion 136 is fitted into the first arc-shaped recess 226. A second transition surface 137 is further formed between the side surface 134 and the top surface 133, and the second transition surface 137 extends obliquely upward from the side surface 134 to the top surface 133. A second arc-shaped protrusion 138 is further disposed on the second transition surface 137. The second arc-shaped protrusion 138 is configured to be inserted into the second arc-shaped recess 228.

Since both side surfaces 224 of the guide rail 22 are provided with the sliding grooves 225 and both side surfaces 134 of the recess 131 of the slider 13 are provided with the protrusions 135. The mating relationship of the sliding slot 225 and the protrusion 135 can prevent the sliding member 10 from moving in the Z-direction when sliding on the guide rail 22, so that the movement of the sliding member 10 is more smooth. Further, since the upper side surface of the sliding groove 225 is provided with the first arc-shaped recess 226 and the upper surface of the protrusion 135 is provided with the first arc-shaped protrusion 136, since the contact surface between the slider 13 and the guide rail 22 is located at the center of the stator 21 and the mover 11 facing upward, the position matching relationship between the guide rail 22 and the slider can be better achieved by the first arc-shaped recess 226 and the first arc-shaped protrusion 136. It is to be understood that the position of the first arc-shaped recess 226 is not limited to the upper side of the sliding groove 225, and it may be disposed on the bottom surface of the sliding groove 225 or the lower side of the sliding groove 225. Similarly, the position of the first arc-shaped protrusion 136 is not limited to the upper surface of the protrusion 135, and it may be disposed on the top surface or the lower surface of the protrusion 135. Specifically, when the bottom surface of the slide groove 225 and the upper surface of the protrusion 135 are located on the center line of the stator 21 and the mover 11, the first arc-shaped recess 226 may be disposed at the bottom surface of the slide groove 225, and the first arc-shaped protrusion 136 may be disposed at the top surface of the protrusion 135. When the height of the upper surface of the projection 135 is lower than the height of the center line of the stator 21 and the mover 11 at the bottom of the sliding groove 225, the first arc-shaped recess 226 may be disposed at the lower side of the sliding groove 225, and the first arc-shaped protrusion 136 may be disposed at the lower side of the projection 135. In the assembling process, the sliding block 13 is fixed on the bearing plate 12 by screws, and then the sliding block 13 is inserted into the guide rail 22 from the side surface of the guide rail 22, so that the bearing plate 12 can slide on the guide rail 22.
