[0048] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0049] According to one aspect of the present invention, a wire management structure motor housing is provided. The wire management structure motor housing can enable the circuits and air paths inside the motor housing to satisfy the up and down movement of the slider of a linear motor. The wire management structure motor housing can be applied to any suitable motor, including but not limited to a linear motor or a linear rotary motor. Therefore, according to another aspect of the present invention, a linear motor and a linear rotary motor are also provided. The wire management structure motor housing, linear motor, and linear rotary motor in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] As Figure 1 、 Figure 2 shown, the motor housing includes a first housing 110 and a second housing 120. The first housing 110 is a trough-shaped structure. Specifically, the first housing 110 is a trough-shaped structure with side plates around it. The second housing 120 is directly mounted at the port of the first housing 110 through bolts.

[0051] The first housing 110 and the second housing 120 can also be in a flat plate structure. A ring-shaped side plate is arranged between the first housing 110 and the second housing 120, and mounting posts are arranged on the side surface of the ring-shaped side plate. The mounting posts can be arranged on the inner side wall of the ring-shaped side plate or on the outer side wall of the ring-shaped side plate. The first housing 110 and the second housing 120 clamp the ring-shaped side plate, and then bolts pass through the mounting posts to fix the first housing 110, the second housing 120 and the ring-shaped side plate.

[0052] The materials of the first housing 110 and the second housing 120 can be aluminum alloy or magnesium alloy. On the premise of ensuring their strength and thermal conductivity, the machining accuracy of the first housing 110 and the second housing 120 can be guaranteed.

[0053] Furthermore, as Figure 8 , Figure 9 shown, a wiring terminal mounting groove 118 and a gas path mounting hole 119 are arranged on the side surface of the first housing 110. Wiring terminals are arranged on the wiring terminal mounting groove 118, and gas path connectors are arranged in the gas path mounting holes 119. A first circuit fixing part 152 and a first gas path fixing part 162 are arranged on the end surface of the first housing 110. A slider is slidably arranged in the first housing 110. In this embodiment, a second circuit fixing part 153 and a second gas path fixing part 163 are arranged on the slider 133 of the linear motor module 130. The linear motor module drives the second circuit fixing part 153 and the second gas path fixing part 163 to move up and down through the slider.

[0054] During the installation process, a circuit unit 150 and a gas path unit 160 need to be installed in the housing. The circuit unit 150 and the gas path unit 160 respectively include a circuit line 151 and a gas path 161. The circuit line 151 passes through the wiring terminal mounting groove, the first circuit fixing part and the second circuit fixing part in sequence, and the gas path 161 passes through the gas path mounting hole, the first gas path fixing part and the second gas path fixing part in sequence, so that the circuit line 151 between the first circuit fixing part and the second circuit fixing part and the gas path 161 between the first gas path fixing part and the second gas path fixing part are set in a U shape. During the process of the linear motor module 130 driving the slider 133 to move up and down, the U-shaped circuit line 151 and gas path 161 increase their travel, avoiding the influence of the travel of the circuit line 151 and the gas path 161 on the movement of the linear motor module 130, making the circuit line 151 and the gas path 161 inside the motor be distributed in an orderly manner, and the travel of the circuit line 151 and the gas path 161 covering the movement interval of the linear motor module 130, improving the safety of the motor operation.

[0055] Further, a wire arranging board 155 is provided at the corner of the first housing 110 corresponding to the circuit 151. The material of the wire arranging board 155 can be the same as that of the first housing 110, and the wire arranging board 155 is integrally formed with the first housing 110, so that the wire arranging board 155 has greater structural strength. The circuit 151 is limited and bent by the wire arranging board 155 and then installed in the first circuit fixing part 152. The circuit 151 is arranged between the wire arranging board 155 and the inner side wall of the first housing 110 to limit the circuit 151, making the wiring of the circuit 151 in the first housing 110 neater. After the second housing 120 and the first housing 110 are installed, the second housing 120 seals the upper port of the wire arranging board 155 to prevent the circuit 151 from detaching from the wire arranging board 155.

[0056] The wire arranging board 155 can also be set as a detachable structure. The wire arranging board 155 is connected to the first housing 110 by bolts, clamping or bonding, which can adapt to the layout requirements of different circuits 151 and is convenient for adjustment. The material of the wire arranging board 155 can be made of insulating material to avoid direct contact between the circuit 151 and the metal shell, improving safety.

[0057] The circuit 151 is a flexible cable, and the circuit 151 is connected to the wiring terminal installation groove 118 and the second circuit fixing part 153 through flexible cable connectors 156 respectively;

[0058] Further, referring to Figure 8 、 Figure 9 , a first air path turning joint 164 is installed in the air path installation hole 119. The first air path fixing part 162 is a second air path turning joint, and the second air path fixing part 163 is a third air path turning joint;

[0059] Specifically, the first air path turning joint 164 is a 90° turn, the second air path turning joint is a 0° turn, and the third air path turning joint is a 145° turn. The air path 161 turning joint is a mature application of the prior art and will not be elaborated in this patent application document. The air path 161 passes through a 90° turn through the first air path turning joint 164 and is arranged close to the side wall of the first housing 110. The air path 161 is bent 90° inside the first housing 110 and then connected to the second air path turning joint, and then extends out in the reverse direction. Then the air path 161 is bent into a U shape and connected to the third air path turning joint, realizing a U-shaped structure with a movable amount of the air path 161 in the first housing 110. The air path 161 can be adjusted as the slider 133 moves up and down.

[0060] The motor housing with a wire management structure is applied to a linear motor. The linear motor includes a circuit unit 150. The linear motor module 130 is installed in the first housing 110. The wire 151 of the circuit unit 150 is introduced into the first housing 110 through the terminal installation slot 118. The middle position of the wire 151 is defined in the first circuit fixing part 152. The end of the wire 151 is fixedly arranged on the second circuit fixing part 153. The wire 151 between the first circuit fixing part 152 and the second circuit fixing part 153 is arranged in a U shape. After passing through the U-shaped arrangement, the wire 151 is connected to the linear motor module 130.

[0061] During the up and down movement of the slider 133 on the mover 132 of the linear motor module 130, the U-shaped arranged wire 151 can provide redundant length for the up and down movement of the slider 133, reduce the vertical height of the housing, and at the same time avoid the arrangement of the wire 151 and the air circuit 161 from affecting each other's movement of the linear motor module 13, making the wire 151 and the air circuit 161 inside the motor distributed in an orderly manner, covering the movement range of the linear motor module 130, and improving the safety of the motor operation.

[0062] The motor housing with a wire management structure is applied to a linear rotary motor, including a linear motor module 130, a rotary motor module 140, a circuit unit 150 and an air circuit unit 160. The linear motor module 130 and the rotary motor module 140 are installed in the motor housing with a wire management structure. The wire 151 of the circuit unit 150 is introduced into the first housing 110 through the terminal installation slot 118. The middle position of the wire 151 is defined in the first circuit fixing part 152. The end of the wire 151 is fixedly arranged on the second circuit fixing part 153. The wire 151 between the first circuit fixing part 152 and the second circuit fixing part 153 is arranged in a U shape. After passing through the U-shaped arrangement, the wire 151 is connected to the linear motor module 130 and the rotary motor module 140. The air circuit 161 of the air circuit unit 160 is introduced into the first housing 110 through the air circuit installation hole 119. The middle position of the air circuit 161 is fixedly arranged on the first air circuit fixing part 162. The end of the air circuit 161 is fixedly arranged on the second air circuit fixing part 163. The wire 151 between the first circuit fixing part 152 and the second circuit fixing part 153 and the air circuit 161 between the first air circuit fixing part 162 and the second air circuit fixing part 163 are arranged in a U shape.

[0063] Avoid the arrangement of the wire 151 and the air circuit 161 from affecting each other's movement of the linear motor module 130, make the wire 151 and the air circuit 161 inside the motor distributed in an orderly manner, cover the movement range of the linear motor module 130, and improve the safety of the motor operation.

[0064] Avoidance parts 111 are provided at the positions corresponding to the motor modules on the first housing 110 and the second housing 120.

[0065] In this embodiment, by providing a clearance portion 111 at the module of the motor corresponding to the first housing 110 and the second housing 120, the clearance portion 111 can create a concave space at the housing corresponding to the module of the motor. On the premise of ensuring the installation distance between the module of the motor and the side wall of the housing, the module of the motor can be closer to the first housing 110 and the second housing 120. The clearance portion 111 provides a certain installation distance for the module of the motor without affecting the working performance of the motor, so that the motor housing can be made thinner.

[0066] Specifically, the clearance portion 111 is a groove provided on the inner end surface of the first housing 110 and the second housing 120;

[0067] Or,

[0068] The clearance portion 111 is a hollowed-out groove opened on the end surface of the first housing 110 and the second housing 120.

[0069] Since opening a hollowed-out groove on the housing and reducing the thickness of the housing will affect its strength, a strengthening structure is provided around the clearance portion 111. In this embodiment, a reinforcing rib is provided around the clearance portion 111, and the strength of the reinforcing rib is greater than that of the housing. The thickness of the reinforcing rib can be the same as the thickness of the housing, or slightly greater than the thickness of the housing without affecting the installation of the internal module. The material of the reinforcing rib can be carbon fiber or glass fiber reinforced plastic, etc.; of course, a reinforcing coating can also be applied to the edge of the clearance portion 111, such as epoxy resin, carbon fiber cloth, ceramic coating, glass fiber reinforced plastic, metal coating, etc.

[0070] The provision of the clearance portion 111 can also reduce the weight of the housing and make the motor lightweight.

[0071] As Figure 3 shown, a sinking groove 112 is provided at the side port of the first housing 110, and the shape of the second housing 120 is the same as that of the sinking groove 112. The second housing 120 is installed in the sinking groove 112. The first housing 110 and the second housing 120 are installed through the cooperation of the sinking groove 112, which can further reduce the thickness of the housing; the surface of the sinking groove 112 is anodized or plated to improve its wear resistance and corrosion resistance. When the first housing 110 and the second housing 120 are installed, a sealing strip or sealant is provided around the sinking groove 112 to prevent external dust and water from entering the housing.

[0072] As Figure 1 、 Figure 3As shown, a guide rail 134 mounting surface 113 is machined on the end face inside the first housing 110, and the guide rail 134 of the linear motor module 130 is mounted on the guide rail 134 mounting surface 113, simplifying the mounting plate structure of the guide rail 134 of the linear motor module 130 and further reducing the overall thickness of the motor. When machining the guide rail 134 mounting surface 113, a high-precision machine tool is used for machining, and then the guide rail 134 mounting surface 113 is ground to improve the machining accuracy and surface smoothness, making the mounting of the guide rail 134 more accurate.

[0073] As Figure 4 , Figure 5 shown, the ultra-thin motor housing is applied to a linear motor. The linear motor module 130 includes a stator 131, a mover 132, a slider 133, and a guide rail 134. The guide rail 134 is mounted on the guide rail 134 mounting surface 113. The stator 131 drives the mover 132 to make a linear movement on the guide rail 134 through the slider 133. The linear motor module 130 is mounted at the clearance part 111 inside the first housing 110, and the guide rail 134 is directly mounted on the housing, reducing the thickness of the motor housing.

[0074] As Figure 5 shown, the ultra-thin motor housing is applied to a linear rotary motor (ZR motor). The linear rotary motor includes a linear motor module 130 and a rotary motor module 140. The linear motor module 130 is mounted at the clearance part 111 inside the first housing 110. The rotary motor module 140 is connected to the slider 133 of the linear motor module 130 through a pressure sensor 135. The rotary motor module 140 is correspondingly arranged at the clearance part 111 inside the first housing 110. On the premise of ensuring the spacing between the linear motor module 130 and the rotary motor module 140 and the inner walls of the first housing 110 and the second housing 120, the overall thickness of the housing can be reduced.

[0075] Furthermore, as Figure 6 shown, a stress relief groove 114 is provided on the side of the first housing 110 close to the linear motor module 130, and the side of the linear motor module 130 is in contact with the inner side of the first housing 110.

[0076] In this embodiment, the linear motor module 130 is installed in the first housing 110, and the rotary motor module 140 is installed on the slider 133 of the linear motor module 130. When the linear motor module 130 and the rotary motor module 140 are operating, especially the linear motor module 130, an uneven stress distribution will be generated. The connection points and contact surfaces between the linear motor and the first housing 110 generate greater stress than other areas. The stress of the entire motor is concentrated on the linear motor module 130. The stress relief groove 114 is closest to the linear motor module 130. The side surface of the linear motor module 130 contacts the inner side surface of the first housing 110, and the stress relief groove 114 is arranged on the side surface of the first housing 110, making the stress of the entire housing more uniform and capable of minimizing the stress of the motor to the greatest extent.

[0077] Furthermore, the stress relief groove 114 is arranged at the middle position of the outer side surface of the first housing 110. The stress relief groove 114 is arranged in a long strip shape and covers at least more than half of the area of the outer side surface of the first housing 110, providing sufficient stress relief paths for the first housing 110 and making the stress relief of the first housing 110 more uniform.

[0078] Furthermore, as Figure 7 shown, an arc groove 115 is arranged on the inner side of the first housing 110 corresponding to the corners of the linear motor module 130. The corners of the installation object are arranged corresponding to the arc groove. During the installation process, the installation object is the linear motor module. A spacing is provided between the corners of the linear motor module 130 and the side surface of the arc groove 115 to achieve an overhead state of the corners of the linear motor module 130.

[0079] Since there is a spacing between the arc groove 115 and the corners of the linear motor module 130, the corner stress of the linear motor module 130 is eliminated. The stress of the housing is mainly concentrated on the two side surfaces rather than at the corners, which helps to disperse the stress. When the motor is operating, the stress is more evenly distributed on the side surfaces of the housing rather than concentrated at the corners, which helps to reduce the local stress concentration phenomenon.

[0080] Furthermore, as Figure 7 shown, the four corners inside the first housing 110 are all processed with arc chamfers, reducing the stress concentration at the corners of the first housing 110, making the stress distribution of the first housing 110 more uniform, improving the strength of the first housing 110, and making the linear motor module 130 and the rotary motor module 140 work more stably.

[0081] Preferably, referring to Figure 7, the side of the first housing 110 in contact with the linear motor module 130 is thickened to form a stress absorption portion 116. Further, the stress absorption portion 116 at least covers the side surface and / or the area outside the side surface of the linear motor module 130. In this embodiment, the stress absorption portion 116 on the short side of the first housing 110 covers the linear motor module 130, and the stress absorption portion 116 on the long side of the first housing 110 covers the area outside the linear motor module 130.

[0082] Since the side of the first housing 110 in contact with the linear motor module 130 is thickened with the stress absorption portion 116, the first housing 110 can better absorb the stress of the linear motor module 130, making the structural strength between the first housing 110 and the linear motor module 130 higher;

[0083] The stress absorption portion 116 can also be set to the entire side surface in contact with the first housing 110, further improving the overall structural strength of the first housing 110, and can more effectively disperse the stress generated by the linear motor module 130, avoiding deformation of the housing during operation.

[0084] Further, referring to Figure 6 , the side of the long side of the first housing 110 extends outward to form a mounting foot 117. In this embodiment, the mounting foot 117 and the stress relief groove 114 are located on the same side of the first housing 110. The thickness of the mounting foot 117 is greater than the thickness of the stress absorption portion 116, making the installation of the first housing 110 more stable. The mounting foot 117 also serves as an additional stress absorption structure, and the mounting foot 117 and the stress relief groove 114 are located in the same plane, making the first housing 110 with the stress relief groove 114 have a stronger structure, more stable stress transfer, and more conducive to the elimination of stress on the first housing 110.

[0085] Referring to Figures 5 - 7 , the motor housing with the stress relief groove 114 is applied to the linear motor. The linear motor module 130 is arranged at a corner of the first housing 110 close to the stress relief structure, and the linear motor module 130 is attached to the side surface of the first housing 110. The first housing 110 disperses and eliminates the stress generated by the linear motor module 130.

[0086] Referring to Figures 5 - 7 , the motor housing with the stress relief groove 114 is applied to the linear rotary motor. The rotary motor module 140 is connected to the slider 133 of the linear motor module 130 through the pressure sensor 135. The stress generated by the rotary motor module 140 is transmitted to the linear motor module 130, and then transmitted to the first housing 110 to eliminate the stress.

[0087] Further, as Figures 8 - 10As shown, the first circuit fixing part 152 includes a base 1521 and a wire arranging part 1522. The base 1521 is detachably installed on the inner end face of the first housing 110. The wire arranging parts 1522 are multiple and are arranged on the base 1521. The gaps between the wire arranging parts 1522 are set as wire arranging grooves 1523. The circuit 151 is arranged in the wire arranging grooves 1523. Specifically, the number of the wire arranging grooves 1523 is three.

[0088] As Figures 8 - 11 shown, a linear motor module 130, a rotary motor module 140, a circuit unit 150, a gas circuit unit 160 and a grating scale 154 are arranged in the motor housing. The grating scale 154 is installed on the side of the rotary motor module 140. The wiring harnesses of the linear motor module 130, the rotary motor module 140 and the grating scale 154 are arranged in the corresponding wire arranging grooves 1523, and the connection between the wiring harnesses and the wire arranging grooves 1523 is non-fixed. While the wiring harnesses of the three do not interfere with each other, the freedom degree of the wiring harnesses is improved, the bending of the wiring harnesses during the movement process is reduced, and the service life of the wiring harnesses is improved.

[0089] The uppermost end of the wire arranging groove 1523 is on the same plane as the port of the first housing 110. When the second housing 120 is installed at the port of the first housing 110, the second housing 120 just seals the notch of the wire arranging groove 1523 to prevent the wiring harness from detaching from the wire arranging groove 1523.

[0090] As Figure 1 , Figures 8 - 11 shown, an installation seat 157 is arranged on the inner end face of the first housing 110 corresponding to the position of the first circuit fixing part 152. The base 1521 is fixed on the installation seat 157 by bolts, which is convenient for the disassembly and assembly of the first circuit fixing part 152.

[0091] The depths of the wire arranging grooves 1523 are different. The number of the second circuit fixing parts 153 is the same as that of the wire arranging grooves 1523. By arranging the wiring harnesses of the linear motor module 130, the rotary motor module 140 and the grating scale 154 in a staggered manner in the wire arranging grooves 1523 with corresponding depths and then correspondingly installing them on the corresponding second circuit fixing parts 153, the neat arrangement of the wiring harnesses is realized.

[0092] Furthermore, as Figure 12 shown, a limiting strip 142 is detachably arranged on the rotary motor module 140. A long hole 143 is opened on the limiting strip 142. The wiring harness of the second circuit fixing part 153 passes through the long hole 143 and then is connected to the rotary motor module 140. The long hole 143 limits the wiring harness of the rotary motor module 140, making the wiring harness arrangement in the housing neater, preventing the wiring harness from contacting the external moving mechanism when the linear motor module 130 and the rotary motor module 140 are working, and ensuring the stable operation of the rotary motor module 140.

[0093] Specifically, a protective ring made of plastic or rubber is provided inside the long strip hole 143, which can prevent the flexible cable from rubbing against the limit strip 142 when it shakes, thus avoiding wear and tear.

[0094] Further, as Figure 12 、 Figure 13 shown, a moving carrier 144 is detachably and fixedly arranged on the rotary motor module 140. An air passage 145 is arranged on the side of the moving carrier 144. The moving carrier 144 is fixedly connected to the slider 133 through a pressure sensor 135. The pressure sensor 135 straddles the moving carrier 144 and a guard plate 136 is fixedly arranged at the air passage 145. An air passage joint is fixedly arranged on the moving carrier 144. The air passage 161 led out by the third air passage steering joint bypasses the air passage 145 and then is connected to the air passage joint. The guard plate 136 protects the air passage 161. At the same time, the air passage 161 is arranged in the air passage 145, preventing the air passage 161 from protruding from the moving carrier 144 and preventing the air passage 161 from rubbing against the side wall of the housing, improving the safety of the system air passage 161 and avoiding damage to the air passage 161.

[0095] The air passage 145 can be two straight channels arranged on the moving carrier 144. The air passage 161 penetrates into one of the straight channels and then winds around the outside of the moving carrier 144 and penetrates out of the other straight channel.

[0096] The air passage 145 can also be a complete channel opened on the moving carrier 144, which is arranged in a U shape on the side of the moving carrier 144.

[0097] Of course, the above two setting methods of the air passage 145 can be inside the moving carrier 144 or in the form of being open on the surface of the moving carrier 144.

[0098] Further, as Figure 14 shown, the motor further includes a carrier block 137 and an elastic member 171. The guide rail 134 of the linear motor module 130 is installed on the first housing 110. The slider 133 of the linear motor module 130 is slidably arranged on the guide rail 134. The carrier block 137 is fixedly arranged on the slider 133. A connecting portion 174 is fixedly arranged on the carrier block 134. One end of the elastic member 171 is connected to the first housing 110, and the other end of the elastic member 171 is fixedly connected to the connecting portion 174. The elastic member is arranged parallel to the guide rail. The elastic member is located between the rotary motor module and the guide rail, so that the pulling force of the elastic member can be closer to the guide rail, and the force application direction of the guide rail is along its length direction.

[0099] The carrier block is provided with a mounting portion for fixedly installing the end of the pressure sensor. The mounting portion is a groove-shaped structure formed on the carrier block. The mounting portion is provided with screw holes, and the pressure sensor is fixed on the mounting portion through bolts. A second gas path fixing portion is fixedly arranged on the carrier block, and a stop block is arranged between the second gas path fixing portion and the mounting portion to prevent the gas path from affecting the detection of the pressure sensor.

[0100] When the linear motor module 130 drives the rotary motor module 140 to move, the elastic member 171 provides a pulling force to the carrier block 137 to offset the self-weights of the slider 133, the carrier block 137, and the rotary motor module 140, and does not affect the detection accuracy of the pressure sensor for the pressure on the rotary motor module 140; the moving carrier 144 and the slider 133 are connected through the pressure sensor. If the elastic member 171 is connected to the moving carrier 144 and the carrier block 137, the elastic member 171 will affect the detection data of the pressure sensor. Therefore, both ends of the elastic member 171 are fixedly connected to the first housing 110 and the carrier block 137 respectively, and the elastic force of the elastic member will not act on the pressure sensor and will not affect the detection result of the pressure sensor.

[0101] Specifically, the linear motion mechanism further includes an adjustment block 172. The adjustment block 172 is installed on the first housing 110. In this embodiment, the elastic member 171 is a spring. One end of the spring is fixedly connected to the adjustment block 172, and the other end of the spring is fixedly connected to the connecting portion 174. The elastic member 171 can also be a pneumatic spring or a hydraulic damper.

[0102] Furthermore, the first housing 110 is provided with an adjustment groove 173 corresponding to the installation position of the adjustment block 172. The adjustment block 172 is installed in the adjustment groove 173. Screw holes are provided in the adjustment groove 173, and strip-shaped screw fixing holes are provided on the adjustment block 172. By adjusting the position of the adjustment block 172 in the adjustment groove 173 and then fixing it with bolts, the pulling force of the spring can be adjusted to reduce the influence of the fatigue deformation of the spring on its pulling force. A limiting block is fixedly arranged directly below the adjustment groove. The distance between the limiting block and the lower end of the adjustment groove is less than the height of the adjustment block, and the adjustment block is slidably arranged in the adjustment groove so that the adjustment block will not slide out from the lower end of the adjustment groove.

[0103] As Figure 15 shown, two bolts are provided on the adjustment block 172, an anti-loosening strip 176 is provided on the adjustment block 172, and two anti-loosening caps 177 are provided on the anti-loosening strip 176. After the adjustment block 172 is fixed at a specified position, the anti-loosening caps 177 are buckled on the bolts to prevent the bolts from loosening.

[0104] Furthermore, as Figure 16As shown in the figure, the linear motion mechanism further includes a collision prevention block 175, which is fixedly arranged on the carrier block 137. The collision prevention block is provided with rubber coating. The collision prevention block 175 is located on the straight line where the guide rail 134 is located. During the process of the slider 133 being driven by the linear motor module 130 to move, when the slider 133 moves to the limit position, the collision prevention block 175 abuts against the guide rail 134, preventing the linear motor module 130 from exceeding the motion stroke and playing a limiting and protective role for the linear motor module 130.

[0105] A linear rotary motor includes the linear motion mechanism according to any one of the above technical solutions.

[0106] Further, as Figures 17 - 20 shown, a shaft sleeve 180 is fixedly arranged at the output end of the rotary motor module 140. Specifically, the shaft sleeve 180 is installed on the moving carrier 144. The output shaft 141 of the rotary motor module 140 passes through the shaft sleeve 180. A positioning plane 181 is arranged on the outer side wall of the shaft sleeve 180, and a positioning groove 182 is opened on the positioning plane 181. During detection, the detection head of the measuring instrument is arranged on the positioning plane 181 or can also be arranged in the positioning groove 182 for distance detection, providing different detection references for the measuring instrument. Thus, through multiple measurements with different detection references, the detection accuracy is improved, and further the installation of the shaft sleeve 180 is more precise; moreover, through the setting of the shaft sleeve, the output shaft of the rotary motor module can be designed longer, and the shaft sleeve protects and limits the output shaft of the rotary motor module.

[0107] The positioning groove 182 can be a concave pit for positioning, or can be a long strip groove or a cross-shaped groove, which can limit the detection head of the measuring instrument and prevent measurement errors caused by the deflection of the position of the measuring instrument during the measurement process.

[0108] Specifically, there are four positioning planes 181, and the four positioning planes 181 respectively correspond to the four faces of the housing. The distances between the shaft sleeve 180 and the four faces of the housing are measured by taking readings, improving the installation accuracy of the shaft sleeve 180.

[0109] A boss 183 is arranged on the installation surface of the shaft sleeve 180, and a groove is correspondingly arranged on the installation surface of the moving carrier 144. When installing the shaft sleeve 180, the boss 183 is inserted into the groove on the moving carrier 144 to achieve the positioning function and improve the installation accuracy.

[0110] Scale lines are arranged on the positioning plane 181, which is convenient for selecting accurate measurement positions and improving the measurement accuracy.

[0111] As Figure 21As shown, a chute 186 is provided on the side surface of the bushing 180 along its axial direction. A wedge block 187 is slidably arranged in the chute 186. By adjusting the position of the wedge block 187, an operation hole 1101 is provided on the side surface of the first housing 110. The bushing 180 passes through the operation hole 1101, so that the wedge block 187 cooperates with the operation hole 1101, thereby adjusting the coaxiality between the bushing 180 and the rotary motor module 140, and making the installation accuracy of the bushing 180 higher.

[0112] Specifically, the chute 186 is arranged on the center line of the positioning plane 181. By adjusting the position of the wedge block 187, the distance between the positioning plane 181 and the side surface of the housing can be directly adjusted, which is convenient for adjustment.

[0113] A sealing gasket 184 is arranged on the installation surface of the bushing 180. The bushing 180 is installed on the moving carrier 144 to prevent air leakage between the bushing 180 and the moving carrier 144.

[0114] A first sealing ring 185 is arranged inside the bushing 180 to seal the output shaft 141 of the rotary motor module 140 and the bushing 180, and prevent air leakage between the bushing 180 and the output shaft 141 of the rotary motor module 140.

[0115] As Figure 5 , Figures 17 - 21 shown, the bushing 180 is applied in a rotary motor. The moving carrier 144 is installed on the rotary motor module 140, the bushing 180 is installed on the moving carrier 144, the output shaft 141 of the rotary motor module 140 passes through the moving carrier 144 and the bushing 180. A second sealing ring 188 is arranged inside the moving carrier 144. An air vent hole 1411 is arranged on the side surface of the output shaft 141 of the rotary motor module 140. The air vent hole 1411 is located between the first sealing ring 185 and the second sealing ring 188. A cavity 189 is arranged between the output shaft 141 of the rotary motor module 140 and the moving carrier 144 and the bushing 180. The first sealing ring 185 and the second sealing ring 188 are located at both ends of the cavity 189. An air duct 1412 is arranged axially on the output shaft 141 of the rotary motor module 140. An air path joint is fixedly arranged on the moving carrier 144 to conduct the air path joint, the air vent hole 1411 and the air duct 1412. A suction cup is installed at the end of the output shaft 141 of the rotary motor module 140 to suck the product. Through the arrangement of the moving carrier 144 and the bushing 180, the length of the output shaft 141 of the rotary motor module 140 can be greatly increased to realize long-distance operation of the suction cup. The cavity 189 can not only provide a channel for gas flow between the air path joint and the air vent hole 1411, but also reduce the contact area between the output shaft 141 of the rotary motor module 140 and the moving carrier 144 and the bushing 180, reduce wear, and extend the service life of the rotary motor module 140.

[0116] As Figure 5 , Figures 17 - 21 shown, the bushing 180 is applied in a linear rotary motor, including a housing composed of a first housing 110 and a second housing 120. The linear motor module 130 is installed in the first housing 110. The rotary motor module 140 is installed on the slider 133 of the linear motor module 130 through a pressure sensor. The moving carrier 144 is installed on the rotary motor module 140. The bushing 180 is installed on the moving carrier 144. The output shaft 141 of the rotary motor module 140 passes through the moving carrier 144 and the bushing 180.
