[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] Example 1: Figure 1 、 Figure 2 and Figure 3 As shown, a narrow motor housing includes an upper housing 11 and a lower housing 12, wherein the upper housing 11 and the lower housing 12 are detachably connected, and the fitting surface of the upper housing 11 and the lower housing 12 is a first reference plane, and a second reference plane is arranged perpendicular to the first reference plane, and a linear motor mounting cavity 59, a connecting carrier mounting cavity 60 and a moving carrier mounting cavity 61 that are interconnected are arranged in the lower housing 12, and the distribution positions of the linear motor mounting cavity 59, the connecting carrier mounting cavity 60 and the moving carrier mounting cavity 61 in the lower housing 12 are triangular in shape in their orthographic projection on the second reference plane.

[0036] The shape of the lower shell 12 can be a hollow cylindrical structure or a hollow rectangular parallelepiped structure with one side open.

[0037] This embodiment is illustrated by taking a rectangular lower shell 12 as an example. A group of mounting seats 19 are fixedly provided on the outer wall of the lower shell 12. In the lower shell 12, the moving carrier mounting cavity 61 is located on the same side of the linear motor mounting cavity 59 and the connecting carrier mounting cavity 60. The linear motor mounting cavity 59 and the connecting carrier mounting cavity 60 are located between the moving carrier mounting cavity 61 and the mounting seat 19. The lower shell 12 can be fixed to the equipment through the mounting seat 19, and the sum of the depths of the linear motor mounting cavity 59 and the connecting carrier mounting cavity 60 is the same as the depth of the moving carrier mounting cavity 61 and does not exceed the depth of the lower shell 12. The sum of the width of the moving carrier mounting cavity 61 and the width of the linear motor mounting cavity 59 or the connecting carrier mounting cavity 60 is equal to the width of the lower shell 12.

[0038] like Figure 3 As shown, by stacking the installation spaces of two components and connecting them with another installation control, the length of the space used when the components are arranged horizontally can be shortened, and the width of the motor can be reduced.

[0039] like Figure 4 As shown, a fixing member 13 is provided between the linear motor mounting cavity 59 and the connection carrier mounting cavity 60. The fixing member 13 is fixed to the inner wall of the lower housing 12 and is used to fix the linear motor and the connection assembly. Specifically, the fixing member 13 can be a plate-like structure, or a bracket or other structure.

[0040] like Figure 1 As shown, a wire-managing plate 15 is fixedly provided on the inner wall of the lower shell 12. There are at least two wire-managing plates 15, which are arranged at intervals. The wires inside the motor can be combed and fixed by the wire-managing plates 15 to prevent the internal wires from being entangled with the moving parts when the motor is running, resulting in wire breakage and damage to the motor.

[0041] like Figure 1 and Figure 2 As shown, a mounting opening 14 is provided on the side wall opposite to the opening on the lower shell 12, and the mounting opening 14 is connected to the linear motor mounting cavity 59. A cover plate 20 is fitted on the mounting opening 14, and a circle of sunken grooves is provided along the edge of the mounting opening 14. The cover plate 20 is located in the sunken groove and is connected to the lower shell 12 by bolts, which can ensure the flatness of the side wall surface of the lower shell 12, and in order to ensure the sealing, a sealing strip is also provided in the sunken groove, and the sealing is achieved by squeezing the sealing strip by the cover plate 20.

[0042] like Figure 5 and Figure 2 As shown, a fixing groove 17 and a fixing hole 18 are also provided on one side wall of the lower shell 12. The fixing hole 18 is used to fix the air inlet nozzle 53, and the fixing groove 17 is used to fix the data interface 54. An output hole 16 is provided on the other opposite side wall. The output hole 16 is connected to the moving carrier mounting cavity 61, so that the output shaft 313 of the motor can pass through the inside of the lower shell 12.

[0043] like Figure 4-10 As shown, a narrow linear motor includes the above-mentioned shell, and also includes a linear motor assembly 21, a connecting assembly and an output assembly 31. The connecting assembly is located in the connecting carrier mounting cavity 60 and is connected to the fixing member 13. The linear motor assembly 21 is fixedly arranged in the linear motor mounting cavity 59 and is connected to the connecting assembly. The output assembly 31 is located in the moving carrier mounting cavity 61 and is connected to the connecting assembly.

[0044] like Figure 8 As shown, the connecting assembly includes a slide rail 223, a slider 224, a mounting frame 221 and a connecting block 222. The mounting frame 221 is fixedly set on the output end of the linear motor assembly 21, the slide rail 223 is fixedly set on the fixing member 13, and the extension direction is the same as the output direction of the linear motor assembly 21, the slider 224 is slidably set on the slide rail 223, the connecting block 222 is fixedly set on the slider 224, and the connecting block 222 is respectively connected to the mounting frame 221 and the output assembly 31.

[0045] like Figure 6 and Figure 7 As shown, a tension spring 56 is further provided on the mounting bracket 221 , and the free end of the tension spring 56 is connected to the inner wall of the lower shell 12 . The tension spring 56 can keep the output shaft 313 of the motor in a retracted state after power is cut off.

[0046] Specifically, a magnetic strip 58 is provided on the connecting block 222, and a reader 57 is provided on the side wall of the lower shell 12 opposite to the magnetic strip 58. The axial movement distance of the output shaft 313 is monitored through the mutual cooperation between the magnetic strip 58 and the reader 57, so as to achieve high-precision control of the movement distance of the output shaft 313.

[0047] Specifically, the output assembly 31 is connected to the connection assembly via a pressure sensor 51 , which can monitor the pressure fed back from the output shaft 313 to prevent the output shaft 313 from damaging the product due to excessive output pressure.

[0048] A narrow ZR motor further includes a rotating motor assembly 41 located in the moving carrier installation cavity 61 , and the rotating motor assembly 41 is fixedly arranged on the output assembly 31 .

[0049] like Figure 10 As shown, the output assembly 31 includes a fixed block 311 and an output shaft 313. The fixed block 311 is provided with a mounting hole 312. A first seal 315 and a second seal 316 are provided in the mounting hole 312. The mounting block is further provided with a sleeve 317. The sleeve 317 is coaxial with the mounting hole 312 and is in communication with each other. The inner diameter of the sleeve 317 is the same as the diameter of the mounting hole 312. A third seal 319 is provided in the sleeve 317. The second seal 316 is located between the first seal 315 and the third seal 319. The output shaft 313 completely passes through the first seal 315, the second seal 316 and the third seal 319, and the diameter of the output shaft 313 is much smaller than the diameter of the mounting hole 312 and the inner diameter of the sleeve 317, so there is a gap for accommodating gas between the output shaft 313 and the mounting hole 312. An air hole 318 is provided on the output shaft 313 along the axial direction, and an air intake hole 314 is also provided on the output shaft 313. The air intake hole 314 is located between the first seal 315 and the second seal 316 and is connected to the air hole 318.

[0050] like Figure 9 As shown, the rotating motor assembly 41 includes a rotating motor body 411 and a flexible coupling 412. The rotating motor body 411 is set on the fixed block 311. The output end of the rotating motor body 411 is connected to the output shaft 313 through the flexible coupling 412. The rotating motor can be protected by the flexible coupling 412.

[0051] An air circuit is provided in the connecting block 222. The input end of the air circuit is connected to the air inlet nozzle 53 through a spiral air tube 52. The output end of the air circuit is connected to the mounting hole 312 between the first seal 315 and the second seal 316 through a flexible hose, so that the air inlet nozzle 53 can be connected to the air hole 318 on the output shaft 313. The rotary motor, linear motor, reader 57 and pressure sensor 51 are connected to the data interface 54 through a data line 55, so that data transmission can be realized and the linear rotary motor can be controlled.

[0052] Operation: When the ZR motor in this embodiment is in operation, it is first secured to the device via the mounting base 19. Then, the air path is connected via the air inlet nozzle 53, and the circuit is connected via the data interface 54. When linear output is required, the linear motor is powered, and the motor mover 212 moves along the motor stator 211, driving the mounting bracket 221. The movement of the mounting bracket 221 also moves the connecting block 222. At this time, driven by the pressure sensor 51, the output assembly 31 also moves, allowing the output shaft 313 to extend or retract from the output hole 16.

[0053] When rotation output is required, the power supply of the rotating motor will be turned on, and the rotating motor will drive the output shaft 313 to rotate through the flexible coupling 412.

[0054] When linear and rotary synchronous output is required, the power of the linear motor and the rotary motor are turned on at the same time. At this time, the linear motor will drive the output shaft 313 to reciprocate along the axial direction, and the rotary motor body 411 will drive the output shaft 313 to rotate.

[0055] In this embodiment, the air pressure in the air hole 318 can also be controlled by the air inlet nozzle 53. The negative pressure can be used to generate negative pressure at the end of the air hole 318 on the output shaft 313, thereby sucking the product.

[0056] Specifically, the motor is connected to the external air pressure equipment through the air inlet nozzle 53. When negative pressure needs to be generated in the air hole 318, air is drawn out through the air inlet nozzle 53. At this time, the external air will enter the air hole 318, and after passing through the suction hole 314, it will enter the gap between the mounting hole 312 and the output shaft 313, and then pass through the hose into the air path on the connecting block 222, flow to the spiral air pipe 52 through the air path, and finally flow out through the air inlet nozzle 53; when the air inlet end of the air hole 318 is blocked, the gas in the air hole 318 will be drawn away, so that negative pressure is formed in the air hole 318, thereby achieving the purpose of grabbing the product.

[0057] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
