Description

Technical Field

[0001] The present invention relates to the technical field of linear motors, and in particular to a position-adjustable double-sided linear motor module. Background Art

[0002] The double-sided linear motor consists of two stators set opposite to each other and a mover in the middle. Each stator contains one or more sets of coils, and the mover is usually equipped with a permanent magnet or other forms of magnetic field generators. When current passes through the stator coil, a magnetic field is generated around the mover. According to the law of electromagnetic induction, the mover is subjected to thrust from both sides and moves along a linear track. Since the thrust comes from both sides, higher thrust density and stability can be achieved.

[0003] In order to facilitate the cleaning of dust accumulated on the surface of one side of the stator permanent magnet array and the stator electromagnetic core array that output magnetic force, and to prevent excessive dust accumulation on the two arrays from affecting the penetration and diffusion of magnetic lines of force or magnetic flux lines, thereby reducing the thrust and performance of the linear motor, the existing linear motor modules are often equipped with cleaning mechanisms for wiping and cleaning the two arrays. However, when these mechanisms are in use, manual force is required or an additional drive motor is required. The auxiliary kinetic energy generated by the stator during sliding operation cannot be used for joint driving. The operation is relatively cumbersome and inconvenient, and it is not conducive to reducing the overall cost and power consumption of the linear motor module. Summary of the invention

[0004] In view of this, the present invention provides a double-sided linear motor module with adjustable position to solve the problem that the cleaning mechanism needs to be operated manually or an additional driving motor needs to be configured when in use, and the auxiliary kinetic energy generated by the stator during sliding operation cannot be used for joint driving, which makes the operation and use more troublesome and inconvenient, and is not conducive to reducing the overall cost and power consumption of the linear motor module.

[0005] The technical solution proposed by the present invention is: a bilateral linear motor module with adjustable position, specifically comprising two symmetrically arranged stator assemblies and a rotor assembly slidably arranged between the two stator assemblies; an electromagnetic core array is arranged on the opposite sides of the two stator assemblies; the rotor assembly as a whole is composed of a rectangular retaining frame and a permanent magnet array embedded and fixed in the rectangular retaining frame;

[0006] A cleaning mechanism capable of simultaneously wiping and cleaning the electromagnet core array and the permanent magnet array is provided on the stator assembly. The cleaning mechanism is driven by the inertial impact force generated during the start-stop conversion of the stator assembly to achieve sliding wiping and cleaning of the electromagnet core array and the permanent magnet array. The cleaning mechanism includes a cleaning sponge, which is rotatably arranged on the cleaning mechanism. The cleaning sponge is located between the permanent magnet array and the electromagnet core array. In the idle state, the cleaning sponge remains parallel and separated from the permanent magnet array and the electromagnet core array. In the use state, the cleaning sponge swings and switches to a state perpendicular to and in pressing contact with the permanent magnet array and the electromagnet core array. A switching drive mechanism is jointly provided on the stator assembly and the rotor assembly, and the switching drive mechanism is used to drive the cleaning sponge to swing and switch to the use posture by using the inertial impact force.

[0007] Further, the main body of the stator assembly is a long vertical plate, and an installation groove is opened along the length direction on one side of the long vertical plate facing the rectangular holding frame. The electromagnet core array is embedded and fixed in the installation groove.

[0008] Further,

[0009] Chute grooves are penetrated along the length direction on the upper and lower side rods of the rectangular holding frame. An auxiliary chute groove equal in length to the chute groove is opened at the bottom side of the chute groove, and a perforation is opened at one end of the chute groove.

[0010] The cleaning mechanism further includes vertical sliding rods, counterweight blocks and rotating shafts. There are two vertical sliding rods arranged symmetrically up and down. The two vertical sliding rods are correspondingly penetrated and slidably matched with the two chute grooves. A counterweight block is welded at the middle position of the vertical sliding rod on the side facing the perforation, and the counterweight block is slidably matched with the chute groove.

[0011] When the vertical sliding rod slides towards the perforation, the counterweight block is penetrated and matched with the perforation. A positioning slider is welded at the bottom side of the middle part of the vertical sliding rod, and the positioning slider is slidably matched with the auxiliary chute groove.

[0012] Two rotating shafts are symmetrically and rotatably installed at both ends of the vertical sliding rod.

[0013] Further, a limiting plate is welded at one end of the rotating shaft away from the vertical sliding rod.

[0014] On the side of the two upper limiting plates facing away from the rotating shafts, two vertically arranged positioning insertion rods are symmetrically welded. A cleaning sponge is jointly sleeved and installed on each two positioning insertion rods. The bottom end part of the positioning insertion rod is in a conical structure and is penetrated and inserted into the corresponding lower limiting plate.

[0015] The cleaning sponge is in a strip-shaped sheet structure. When the cleaning sponge switches to a posture perpendicular to the permanent magnet array and the electromagnet core array, the two long side parts of it are respectively in abutting contact with the permanent magnet array and the electromagnet core array.

[0016] Further, the switching drive mechanism includes an incomplete positioning ring, an L-shaped transmission rod, a vertical transmission shaft, and a drive frame with a right trapezoidal structure;

[0017] Two incomplete positioning rings are welded to the two protruding parts of the vertical slide bars on the upper side out of the sliding grooves. Two L-shaped transmission rods are welded to the positions of the two upper side rotating shafts close to the vertical slide bars. The top parts of the L-shaped transmission rods are in sliding fit with the corresponding incomplete positioning rings, and an arc-shaped spring is sleeved on the part of the incomplete positioning ring between the L-shaped transmission rod and the vertical slide bar;

[0018] A vertical transmission shaft is welded to the top of the L-shaped transmission rod. Two drive frames are symmetrically welded to the positions above the sliding grooves on the upper side rod of the rectangular holding frame. In the initial state, the vertical transmission shaft abuts against the inclined side rod of the drive frame;

[0019] The vertical slide bar is positioned at the end of the sliding groove far from the perforation in the idle state. A positioning bolt is screwed and installed through the bottom of one end of the lower side rod of the rectangular holding frame. The top end of the positioning bolt abuts against the lower side vertical slide bar in the idle state for tightly positioning the lower side vertical slide bar.

[0020] Further, two strip-shaped tracks with a U-shaped cross-section are symmetrically welded to the upper and lower sides of the stator assembly, and two connecting frames with an overall rectangular structure are symmetrically fixed between the two ends of the stator assembly.

[0021] Further, a horizontal carrier plate is welded to the top of the rectangular holding frame. Two rows of vertical limiting rods are symmetrically welded and suspended on the bottom sides of the two short side parts of the horizontal carrier plate. The two rows of vertical limiting rods are respectively in sliding fit with the U-shaped track grooves on the upper two strip-shaped tracks;

[0022] Two rows of L-shaped limiting rods are symmetrically welded to both sides of the lower side rod of the rectangular holding frame. The two rows of L-shaped limiting rods are respectively in sliding fit with the U-shaped track grooves on the lower two strip-shaped tracks.

[0023] Further, a limiting ring is welded and sleeved on the position of the rotating shaft close to the vertical slide bar, and a limiting ring is fixed to the end of the rotating shaft far from the limiting plate. The limiting ring and the limiting ring respectively abut against the upper and lower ends of the vertical slide bar;

[0024] The limiting ring on the bottom side rotating shaft is locked and fixed to the rotating shaft by bolts.

[0025] Further, it further includes a long strip-shaped base. Two vertical support plates are symmetrically welded to the top sides of the two end parts of the long strip-shaped base. The top ends of the two vertical support plates are respectively welded and fixed to the connecting frame.

[0026] A position-adjustable double-sided linear motor module provided by the present invention has the following beneficial effects:

[0027] 1. Through two longitudinally arranged sliding rods and two counterweights, during the sliding operation of the rotor assembly, the two cleaning sponges can wipe and clean the electromagnet core array and the permanent magnet array by using the inertial impact force generated during the dynamic-static switching. Compared with the prior art, it saves the trouble of manually exerting additional force to drive the two cleaning sponges to slide, and can also eliminate the need to additionally configure a driving motor for the two cleaning sponges. It is convenient to operate and use, which helps to indirectly reduce the overall power consumption and cost of the linear motor module.

[0028] 2. Through the power transmission between the erected transmission shaft and the rectangular holding frame, the cleaning sponge can also swing and switch between the idle state and the use state by using the inertial impact force of the rotor assembly. This saves the trouble of manually swinging and switching the use posture of the cleaning sponge before and after each cleaning operation. It is convenient to operate and use, which helps to simplify the cleaning operation steps of the electromagnet core array and the permanent magnet array and indirectly improve the cleaning operation efficiency.

[0029] 3. When the erected transmission shaft continuously slides relying on the horizontally arranged side rod, it can be blocked and limited by the horizontally arranged side rod of the rectangular holding frame to be in a state far from the upper side rod of the rectangular holding frame and keep the cleaning sponge in a state of pressing and contacting the electromagnet core array and the permanent magnet array continuously, so that the cleaning sponge can continuously and effectively wipe and clean the electromagnet core array and the permanent magnet array when reciprocatingly sliding along the chute. This saves the trouble of manually positioning and holding the cleaning sponge in the use state during each cleaning operation, which helps to further simplify the operation and use steps of the cleaning operation and further improve the cleaning operation efficiency.

[0030] 4. In the idle state, when the cleaning sponge is kept parallel and separated from the electromagnet core array and the permanent magnet array, two vertical ventilation grooves are formed between the permanent magnet array and the electromagnet core array. The two vertical ventilation grooves can ensure the smoothness of the heat dissipation channel between the electromagnet core array and the permanent magnet array, and prevent the cleaning sponge from blocking the heat dissipation channel in the state of being vertically abutted and contacting the electromagnet core array and the permanent magnet array for a long time in the idle state, which affects the normal and effective heat dissipation of the electromagnet core array and the permanent magnet array.

[0050] The following is an embodiment provided by the present invention. Please refer to Figures 1 to 11 :

[0051] The present invention provides a bilaterally linear motor module with adjustable position, including two symmetrically arranged stator assemblies 1 and a rotor assembly 2 slidably arranged between the two stator assemblies 1; on one side of each of the two stator assemblies 1 facing each other, an electromagnet core array 102 is provided; the rotor assembly 2 as a whole is composed of a rectangular holding frame 201 and a permanent magnet array 202 fixedly embedded in the rectangular holding frame 201 (in combination with Figure 1 and Figure 6 ); there are two heat dissipation channels 106 formed at intervals between the electromagnet core array 102 and the permanent magnet array 202, and the heat dissipation channels 106 are used to dissipate the heat generated by the electromagnet core array 102 and the permanent magnet array 202 during use;

[0052] A cleaning mechanism capable of simultaneously wiping and cleaning the electromagnet core array 102 and the permanent magnet array 202 is provided on the stator assembly 1. The cleaning mechanism is driven by the inertial impact force generated when the stator assembly 1 starts and stops, so as to realize the sliding wiping and cleaning of the electromagnet core array 102 and the permanent magnet array 202; the cleaning mechanism includes a cleaning sponge 207, the cleaning sponge 207 is rotatably arranged on the cleaning mechanism, the cleaning sponge 207 is located between the permanent magnet array 202 and the electromagnet core array 102, and in the idle state, the cleaning sponge 207 remains parallel and separated from the permanent magnet array 202 and the electromagnet core array 102, and in the use state, the cleaning sponge 207 swings and switches to a state perpendicular to and pressing against the permanent magnet array 202 and the electromagnet core array 102; a switching drive mechanism is jointly provided on the stator assembly 1 and the rotor assembly 2, and the switching drive mechanism is used to drive the cleaning sponge 207 to swing and switch to the use posture by using the inertial impact force.

[0053] Preferably, the main body of the stator assembly 1 is a long vertical plate 101 (in combination with Figure 1 and Figure 11 ), and an installation groove 1011 is formed along the length direction on one side of the long vertical plate 101 facing the rectangular holding frame 201, and the electromagnet core array 102 is fixedly embedded in the installation groove 1011.

[0054] Preferably, sliding grooves 2011 are formed through the upper and lower side rods of the rectangular holding frame 201 along the length direction, and auxiliary sliding grooves 2013 (as shown in Figure 8 shown) of the same length as the sliding grooves 2011 are formed at the bottom sides of the sliding grooves 2011, and perforations 2012 are formed at one ends of the sliding grooves 2011;

[0055] The cleaning mechanism further includes vertically arranged sliding rods 204, counterweight blocks 2042 and rotating shafts 206. There are two vertically arranged sliding rods 204 symmetrically arranged up and down. The two vertically arranged sliding rods 204 penetrate and are slidably matched with the two sliding grooves 2011 correspondingly. A counterweight block 2042 is welded at the middle position on the side of the vertically arranged sliding rod 204 facing the perforation 2012, and the counterweight block 2042 is slidably matched with the sliding groove 2011;

[0056] When the vertically arranged sliding rod 204 slides towards the perforation 2012, the counterweight block 2042 is penetrated and matched with the perforation 2012. A positioning slider 2043 is welded at the bottom side of the middle part of the vertically arranged sliding rod 204, and the positioning slider 2043 is slidably matched with the auxiliary sliding groove 2013;

[0057] Two rotating shafts 206 are symmetrically and rotatably installed at both ends of the vertically arranged sliding rod 204.

[0058] Preferably, a limiting plate 2061 is welded at one end of the rotating shaft 206 away from the vertically arranged sliding rod 204;

[0059] On the side of the two upper limiting plates 2061 facing away from the rotating shafts 206, two vertically arranged positioning insertion rods 2062 are symmetrically welded. A cleaning sponge 207 is sleeved and installed on each two positioning insertion rods 2062. The bottom end part of the positioning insertion rod 2062 is in a conical structure and is penetrated and inserted into the corresponding lower limiting plate 2061. The cleaning sponge 207 is limited between the two upper and lower corresponding limiting plates 2061;

[0060] The cleaning sponge 207 is in a strip-shaped sheet structure. When the cleaning sponge 207 is switched to a posture perpendicular to the permanent magnet array 202 and the electromagnet core array 102, the two long side parts of it are respectively in contact with the permanent magnet array 202 and the electromagnet core array 102.

[0061] Preferably, two strip-shaped tracks 103 with a U-shaped cross-section are symmetrically welded on the upper and lower sides of the stator assembly 1, and two connecting frames 104 with an overall rectangular structure are symmetrically fixed between the two ends of the stator assembly 1.

[0062] Preferably, a horizontal carrier plate 209 is welded at the top end of the rectangular holding frame 201. Two rows of vertical limiting rods 2091 are symmetrically welded and suspended at the bottom sides of the two short side parts of the horizontal carrier plate 209. The two rows of vertical limiting rods 2091 are slidably matched with the U-shaped track grooves on the two upper strip-shaped tracks 103 correspondingly;

[0063] On both sides of the lower side rod of the rectangular holding frame 201, two rows of L-shaped limiting rods 203 are symmetrically welded, and the two rows of L-shaped limiting rods 203 are respectively and slidably engaged with the U-shaped track grooves on the two long strip tracks 103 at the lower side.

[0064] Preferably, the switching drive mechanism includes an incomplete positioning ring 2041, an L-shaped transmission rod 2064, a vertical transmission shaft 2065, and a drive frame 208 with a right trapezoidal structure;

[0065] On the two parts of the upper two vertical sliding rods 204 protruding from the sliding groove 2011, horizontally arranged incomplete positioning rings 2041 are welded. On the upper two rotating shafts 206, at positions close to the vertical sliding rods 204, L-shaped transmission rods 2064 are welded. The top part of the L-shaped transmission rod 2064 is slidably engaged with the incomplete positioning ring 2041 at the corresponding position, and an arc-shaped spring is sleeved on the part of the incomplete positioning ring 2041 located between the L-shaped transmission rod 2064 and the vertical sliding rod 204;

[0066] The top of the L-shaped transmission rod 2064 is welded with a vertical transmission shaft 2065. On the upper side rod of the rectangular holding frame 201, at positions above the sliding groove 2011, two drive frames 208 are symmetrically welded. In the initial state, the vertical transmission shaft 2065 abuts against the inclined side rod of the drive frame 208 (refer to Figure 7 );

[0067] The vertical sliding rod 204 is positioned at the end of the sliding groove 2011 far from the perforation 2012 in the idle state. At the bottom of one end of the lower side rod of the rectangular holding frame 201, a positioning bolt 205 is installed through screwing (refer to Figure 6 ), and the top of the positioning bolt 205 abuts against the lower vertical sliding rod 204 in the idle state for tightly positioning the lower vertical sliding rod 204;

[0068] When cleaning the dust on the electromagnet core array 102 and the permanent magnet array 202, it is necessary to rotate and position the bolt 205 to loosen the vertical slide bar 204 on the lower side, and swing and switch the cleaning sponge 207 to the use state where it is perpendicular to and in pressing contact with the permanent magnet array 202 and the electromagnet core array 102. In this state, when the rotor assembly 2 slides along the four long strip tracks 103, the two vertical slide bars 204, the two counterweight blocks 2042, and the two cleaning sponges 207 can be driven by the inertial impact force generated when switching from the stationary state to the moving state or from the moving state to the stationary state to slide reciprocally along the two chutes 2011, so as to wipe and clean the dust accumulated on the opposite side surfaces of the electromagnet core array 102 and the permanent magnet array 202. In this way, through the two vertical slide bars 204 and the two counterweight blocks 2042, the two cleaning sponges 207 can utilize the inertial impact force generated during the sliding operation of the rotor assembly 2 when switching between the moving and stationary states to wipe and clean the electromagnet core array 102 and the permanent magnet array 202. Compared with the prior art, it saves the trouble of manually exerting additional force to drive the two cleaning sponges 207 to slide, and also eliminates the need to additionally configure a driving motor for the two cleaning sponges 207, making the operation and use convenient, which helps to indirectly reduce the overall power consumption and cost of the linear motor module; Since in the initial state, the vertical transmission shaft 2065 abuts against the inclined side rod of the driving frame 208, thus during the above process, when the vertical slide bar 204 is driven to slide towards the through hole 2012, under the blocking and pushing of the inclined side rod of the driving frame 208, the vertical transmission shaft 2065 together with the L-shaped transmission rod 2064 can be driven to slide along the incomplete positioning ring 2041 in a direction away from the rectangular holding frame 201, and drive the rotating shaft 206 and the cleaning sponge 207 to rotate in the same direction, switching the cleaning sponge 207 from the idle state where it is parallel to and separated from the electromagnet core array 102 and the permanent magnet array 202 to the use state where it is perpendicular to and in contact with the electromagnet core array 102 and the permanent magnet array 202;

[0069] When the L-shaped transmission rod 2064 is driven to slide away from the rectangular holding frame 201, it compresses the arc-shaped spring sleeved on the incomplete positioning ring 2041. When the vertical slide bar 204 is slid back to the idle state after the cleaning operation is completed, the vertical transmission shaft 2065 is separated from the horizontal side rod of the driving frame 208. At this time, the vertical slide bar 204 loses the pushing and holding force from the horizontal side rod and can be pushed back by the arc-shaped spring on the incomplete positioning ring 2041 to the initial state where it abuts against the end part of the inclined side rod of the driving frame 208 (refer to Figure 6 and Figure 7 ), and drives the cleaning sponge 207 to swing back to the idle state where it is parallel to and separated from the electromagnet core array 102 and the permanent magnet array 202;

[0070] The arc-shaped spring on the incomplete positioning ring 2041 can continuously push and hold the cleaning sponge 207 in a state of parallel separation from the electromagnet core array 102 and the permanent magnet array 202 in the idle state; in the idle state, when the cleaning sponge 207 is kept in a state of parallel separation from the electromagnet core array 102 and the permanent magnet array 202, two vertical ventilation grooves 105 are formed between the permanent magnet array 202 and the electromagnet core array 102 (refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 ). The two vertical ventilation grooves 105 can ensure the smoothness of the heat dissipation channel 106 between the electromagnet core array 102 and the permanent magnet array 202, and prevent the cleaning sponge 207 from blocking the heat dissipation channel 106 when it is in a state of perpendicular abutting contact with the electromagnet core array 102 and the permanent magnet array 202 for a long time in the idle state, which affects the normal and effective heat dissipation of the electromagnet core array 102 and the permanent magnet array 202;

[0071] Based on the above, through the power transmission between the vertical transmission shaft 2065 and the rectangular holding frame 201, the cleaning sponge 207 can also swing and switch between the idle state and the use state by using the inertial impact force of the rotor assembly 2, which saves the trouble of manually swinging and switching the use posture of the cleaning sponge 207 before and after each cleaning operation. The operation is convenient and helps to simplify the cleaning operation steps of the electromagnet core array 102 and the permanent magnet array 202, and indirectly improves the cleaning operation efficiency;

[0072] In the above process, when the cleaning sponge 207 is driven to the vertical state, the vertical transmission shaft 2065 is far from the upper side rod of the rectangular holding frame 201 and the distance between the vertical transmission shaft 2065 and the upper side rod reaches the maximum state. At this time, the maximum distance is equal to the distance between the horizontal side rod of the rectangular holding frame 201 and the upper side rod, which enables the vertical transmission shaft 2065 to cross the inclined side rod of the driving frame 208 and fit and contact with the horizontal side rod of the rectangular holding frame 201 and continuously slide reciprocally relying on the horizontal side rod of the rectangular holding frame 201. When the vertical transmission shaft 2065 continuously slides relying on the horizontal side rod, it can be blocked and limited by the horizontal side rod of the rectangular holding frame 201 in a state far from the upper side rod of the rectangular holding frame 201 and keep the cleaning sponge 207 in a state of top pressing contact with the electromagnet core array 102 and the permanent magnet array 202, so that the cleaning sponge 207 can continuously and effectively wipe and clean the electromagnet core array 102 and the permanent magnet array 202 when sliding reciprocally along the chute 2011. This saves the trouble of manually positioning and holding the cleaning sponge 207 in the use state during each cleaning operation, helps to further simplify the operation steps of the cleaning operation, and further improves the cleaning operation efficiency;

[0073] In the idle state, the cleaning sponge 207 can be fixedly connected and positioned in the heat dissipation channel 106 by the positioning bolt 205 pressing against and positioning the longitudinally arranged sliding rod 204 at one end far from the perforation 2012. Such a setting can prevent the cleaning sponge 207 from lacking positioning and continuously reciprocating and sliding along the heat dissipation channel 106 under the action of the inertial impact force during the operation of the rotor assembly 2, causing cutting interference to the magnetic force lines and magnetic induction lines generated by the permanent magnet array 202 and the electromagnet core array 102, reducing the thrust applied to the rotor assembly 2 when the magnetic force lines and magnetic induction lines interact with each other, and affecting the output power of the rotor assembly 2.

[0074] Preferably, a limiting ring 2066 is welded and sleeved at a position on the rotating shaft 206 close to the longitudinally arranged sliding rod 204, and a limiting disk 2063 is fixed at one end of the rotating shaft 206 far from the limiting plate 2061. The limiting ring 2066 abuts against and contacts the end of the longitudinally arranged sliding rod 204 far from the limiting plate 2061, and the limiting disk 2063 abuts against and contacts the end of the longitudinally arranged sliding rod 204 close to the limiting plate 2061;

[0075] The limiting ring 2066 on the bottom-side rotating shaft 206 is locked and fixed to the rotating shaft 206 by bolts;

[0076] When disassembling and replacing the cleaning sponge 207, it is necessary to first loosen and remove the limiting ring 2066 on the bottom-side rotating shaft 206, and push up the bottom-side rotating shaft 206 and the limiting plate 2061 thereon. When the bottom-side rotating shaft 206 is pushed up, the cleaning sponge 207 is temporarily compressed by the limiting plate 2061 thereon and separated from the bottom-side longitudinally arranged sliding rod 204. After the bottom-side rotating shaft 206 is separated from the bottom-side longitudinally arranged sliding rod 204, the bottom-side longitudinally arranged sliding rod 204 is pushed away from directly below the bottom-side rotating shaft 206, and then the bottom-side rotating shaft 206 and the limiting plate 2061 thereon are slid down and separated from the two positioning insertion rods 2062. Finally, the cleaning sponge 207 is extracted and separated from the two positioning insertion rods 2062, and a new cleaning sponge 207 is re-sleeved and inserted onto the two positioning insertion rods 2062 to complete the replacement of the cleaning sponge 207.

[0077] Preferably, it further includes a long-strip base 3. At the top side of both ends of the long-strip base 3, two vertical support plates 301 are symmetrically welded. The tops of the two vertical support plates 301 are respectively welded and fixed to the connecting frame 104;

[0078] The long-strip base 3 is fixedly installed on the machine table or the frame by bolts, which enables the linear motor module to adjust the installation position as needed.

[0079] Working principle of this embodiment: The top end of the positioning bolt 205 abuts against the lower longitudinal slide bar 204 in the idle state for tightly positioning the lower longitudinal slide bar 204. When cleaning the dust on the electromagnet core array 102 and the permanent magnet array 202, it is necessary to rotate the positioning bolt 205 to loosen the lower longitudinal slide bar 204, and swing the cleaning sponge 207 to switch it to the use state where it is perpendicular to and in pressing contact with the permanent magnet array 202 and the electromagnet core array 102. In this state, the two longitudinal slide bars 204, the two counterweight blocks 2042, and the two cleaning sponges 207 can be driven by the inertial impact force generated when the rotor assembly 2 slides along the four long strip tracks 103 and switches from the stationary state to the moving state or from the moving state to the stationary state, and slide reciprocally along the two chutes 2011 to wipe and clean the dust accumulated on the opposite side surfaces of the electromagnet core array 102 and the permanent magnet array 202;

[0080] Since in the initial state, the vertical transmission shaft 2065 abuts against the inclined side rod of the driving frame 208, thus in the above process, when the longitudinal slide bar 204 is driven to slide towards the perforation 2012, under the blocking and pushing of the inclined side rod of the driving frame 208, the vertical transmission shaft 2065 together with the L-shaped transmission rod 2064 can be driven to slide along the incomplete positioning ring 2041 away from the rectangular holding frame 201, and drive the rotating shaft 206 and the cleaning sponge 207 to rotate in the same direction, switching the cleaning sponge 207 from the idle state parallel and separated from the electromagnet core array 102 and the permanent magnet array 202 to the use state where it is perpendicular and in contact with the electromagnet core array 102 and the permanent magnet array 202;

[0081] In the above process, when the cleaning sponge 207 is driven to the vertical state, the upper side rod of the vertical transmission shaft 2065 is far away from the rectangular holding frame 201 and the distance between it and this upper side rod reaches the maximum state. At this time, this maximum distance is equal to the distance between the horizontal side rod of the rectangular holding frame 201 and this upper side rod, which enables the vertical transmission shaft 2065 to cross the inclined side rod of the driving frame 208 and fit in contact with the horizontal side rod of the rectangular holding frame 201 and continuously slide reciprocally relying on the horizontal side rod of the rectangular holding frame 201. When the vertical transmission shaft 2065 continuously slides relying on the horizontal side rod, it can be blocked and limited by the horizontal side rod of the rectangular holding frame 201 to be in the state far away from the upper side rod of the rectangular holding frame 201 and keep the cleaning sponge 207 continuously in the state of pressing contact with the electromagnet core array 102 and the permanent magnet array 202, so that the cleaning sponge 207 can continuously and effectively wipe and clean the electromagnet core array 102 and the permanent magnet array 202 when sliding reciprocally along the chute 2011;

[0082] When the L-shaped transmission rod 2064 is driven to slide away from the rectangular holding frame 201, it compresses the arc-shaped spring sleeved on the incomplete positioning ring 2041. When the longitudinal sliding rod 204 slides back to the idle state after the cleaning operation is completed, the vertical transmission shaft 2065 is separated from the horizontal side rod of the driving frame 208. At this time, the longitudinal sliding rod 204 loses the pushing and holding force from the horizontal side rod and can be pushed back by the arc-shaped spring on the incomplete positioning ring 2041 to the initial state where it abuts against the end part of the inclined side rod of the driving frame 208 (refer to Figure 6 and Figure 7 ), and the cleaning sponge 207 is driven to swing to the idle state parallel and separated from the electromagnet core array 102 and the permanent magnet array 202; the arc-shaped spring on the incomplete positioning ring 2041 can continuously push and hold the cleaning sponge 207 in the state of being parallel and separated from the electromagnet core array 102 and the permanent magnet array 202 in the idle state.
