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

[0006] Furthermore, the main body of the stator assembly is a long vertical plate, and a mounting groove is opened along the length direction on one side of the long vertical plate facing the rectangular retaining frame, and the electromagnetic core array is embedded and fixed in the mounting groove.

[0007] Furthermore, The upper and lower side bars of the rectangular holding frame are provided with a slide groove running through them along the length direction, the bottom side of the slide groove is provided with an auxiliary slide groove of the same length as the slide groove, and one end of the slide groove is provided with a through hole; The cleaning mechanism also includes a longitudinal slide bar, a counterweight block and a rotating shaft. The longitudinal slide bar is symmetrically arranged at two locations, and the two longitudinal slide bars correspond to the two slide grooves and penetrate and slide in cooperation. A counterweight block is welded at the middle position of the longitudinal slide bar on the side facing the perforation, and the counterweight block slides in cooperation with the slide groove. When the longitudinal slide bar slides toward the through hole, the counterweight block fits through the through hole, a positioning slide block is welded on the bottom side of the middle part of the longitudinal slide bar, and the positioning slide block fits in a sliding manner with the auxiliary slide groove; Two rotating shafts are symmetrically mounted at both ends of the longitudinal slide bar.

[0008] Furthermore, a limiting plate is welded to one end of the rotating shaft away from the longitudinal sliding rod; Two vertically arranged positioning rods are symmetrically welded on the side of the two upper limit plates away from the rotating shaft. A cleaning sponge is installed on each of the two positioning rods. The bottom end of the positioning rod is a conical structure and is inserted and matched with the limit plates at the corresponding position on the lower side. The cleaning sponge is in a strip-shaped sheet structure. When the cleaning sponge is switched to a posture perpendicular to the permanent magnet array and the electromagnet core array, two long side portions of the cleaning sponge are in contact with the permanent magnet array and the electromagnet core array respectively.

[0009] Furthermore, the switching drive mechanism includes an incomplete positioning ring, an L-shaped transmission rod, a vertical transmission shaft and a driving frame of a right-angle trapezoidal structure; Both parts of the two vertically arranged sliding rods protruding from the chute on the upper side are welded with incomplete positioning rings. L-shaped transmission rods are welded at positions on the two upper-side rotating shafts close to the vertically arranged sliding rods. The top parts of the L-shaped transmission rods are slidably matched with the corresponding incomplete positioning rings, and an arc-shaped spring is sleeved on the part of the incomplete positioning ring located between the L-shaped transmission rod and the vertically arranged sliding rod; The top of the L-shaped transmission rod is welded with a vertical transmission shaft. Two driving frames are symmetrically welded at positions above the chute 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 driving frame; The vertically arranged sliding rod is positioned at one end of the chute away 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 of the positioning bolt abuts against the lower vertically arranged sliding rod in the idle state for tightly positioning the lower vertically arranged sliding rod.

[0010] Furthermore, two strip-shaped tracks with a U-shaped cross-section are symmetrically welded on the upper and lower sides of the stator assembly, and two connecting frames with an overall H-shaped structure are symmetrically fixed between the two ends of the stator assembly.

[0011] Furthermore, a horizontal carrier plate is welded at the top of the rectangular holding frame. Two rows of vertical limiting rods are symmetrically welded and suspended at the bottom sides of the two short sides of the horizontal carrier plate. The two rows of vertical limiting rods are slidably matched with the U-shaped track grooves on the two upper strip-shaped tracks; Two rows of L-shaped limiting rods are symmetrically welded on both sides of the lower-side rod of the rectangular holding frame. The two rows of L-shaped limiting rods are slidably matched with the U-shaped track grooves on the two lower strip-shaped tracks.

[0012] Furthermore, a limiting ring is welded and sleeved at a position on the rotating shaft close to the vertically arranged sliding rod. A limiting ring is fixed at one end of the rotating shaft away from the limiting plate. The limiting ring and the limiting ring respectively abut against the upper and lower ends of the vertically arranged sliding rod; The limiting ring on the bottom-side rotating shaft is locked and fixed to the rotating shaft by bolts.

[0013] Furthermore, it further includes a long strip-shaped base. Two vertical support plates are symmetrically welded on the top sides of the two end parts of the long strip-shaped base. The tops of the two vertical support plates are respectively welded and fixed to the connecting frame.

[0014] A position-adjustable double-sided linear motor module provided by the present invention has the following beneficial effects: 1. Through two longitudinal sliding rods and two counterweights, the two cleaning sponges can utilize the inertial impact force generated when the rotor assembly switches between dynamic and static during sliding operation to wipe and clean the electromagnetic core array and the permanent magnet array. Compared with the existing technology, it eliminates the trouble of requiring additional manual effort to implement sliding drive for the two cleaning sponges, and it can also avoid the need to additionally configure drive motors for the two cleaning sponges. It is easy to operate and use, which helps to indirectly reduce the overall power consumption and cost of the linear motor module.

[0015] Second, through the power transmission of the vertical transmission shaft and the rectangular retaining frame, the cleaning sponge can also use the inertial impact force of the rotor assembly to swing and switch between the idle state and the use state, which saves the trouble of manually swinging and switching the use posture of the cleaning sponge before and after each cleaning operation. It is easy to operate and use, which helps to simplify the cleaning operation steps of the electromagnetic core array and the permanent magnet array, and indirectly improves the cleaning operation efficiency.

[0016] 3. When the vertical transmission shaft continues to slide relying on the horizontal side rod, it can be blocked by the horizontal side rod of the rectangular retaining frame and limited to a state away from the upper side rod of the rectangular retaining frame and the cleaning sponge can be continuously kept in a state of top pressure contact with the electromagnet core array and the permanent magnet array, so that the cleaning sponge can continuously and effectively wipe and clean the electromagnet core array and the permanent magnet array when sliding back and forth along the slide groove. This saves the trouble of manually positioning the cleaning sponge and keeping it in a use state during each cleaning operation, helps to further simplify the operating steps of the cleaning operation, and further improve the efficiency of the cleaning operation.

[0017] 4. In the idle state, when the cleaning sponge remains parallel and separated from the electromagnetic core array and the permanent magnet array, two vertical ventilation grooves are formed between the permanent magnet array and the electromagnetic core array. The two vertical ventilation grooves can ensure that the heat dissipation channel between the electromagnetic core array and the permanent magnet array is unobstructed, thereby preventing the cleaning sponge from being in a state of vertical abutment with the electromagnetic core array and the permanent magnet array for a long time in the idle state, thereby blocking the heat dissipation channel and affecting the normal and effective heat dissipation of the electromagnetic core array and the permanent magnet array.

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention.

Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0023] The following is an embodiment of the present invention, please refer to Figures 1 to 11 : The present invention proposes a position-adjustable bilateral linear motor module, comprising two symmetrically arranged stator assemblies 1 and a rotor assembly 2 slidably arranged between the two stator assemblies 1; an electromagnetic core array 102 is arranged on the opposite sides of the two stator assemblies 1; the rotor assembly 2 as a whole is composed of a rectangular retaining frame 201 and a permanent magnet array 202 embedded and fixed in the rectangular retaining frame 201 (combined with Figure 1 and Figure 6 ); Two heat dissipation channels 106 are formed between the electromagnetic core array 102 and the permanent magnet array 202, and the heat dissipation channels 106 are used to dissipate the heat generated by the electromagnetic core array 102 and the permanent magnet array 202 during use; The stator assembly 1 is provided with a cleaning mechanism that can wipe and clean the electromagnetic core array 102 and the permanent magnet array 202 at the same time. The cleaning mechanism is driven by the inertial impact force generated by the stator assembly 1 during the start-stop conversion to achieve sliding wiping cleaning of the electromagnetic core array 102 and the permanent magnet array 202; the cleaning mechanism includes a cleaning sponge 207, which is rotatably arranged on the cleaning mechanism, and the cleaning sponge 207 is located between the permanent magnet array 202 and the electromagnetic core array 102. In an idle state, the cleaning sponge 207 remains in a state parallel to and separated from the permanent magnet array 202 and the electromagnetic core array 102. In a use state, the cleaning sponge 207 swings and switches to a state perpendicular to and in pressing contact with the permanent magnet array 202 and the electromagnetic core array 102; the stator assembly 1 and the rotor assembly 2 are jointly provided with a switching drive mechanism, which is used to drive the cleaning sponge 207 to swing and switch the use posture by using the inertial impact force.

[0024] Preferably, the main body of the stator assembly 1 is a long vertical plate 101 (combined with Figure 1 and Fig.11 ), a mounting groove 1011 is opened along the length direction on one side of the long vertical plate 101 facing the rectangular retaining frame 201, and the electromagnetic core array 102 is embedded and fixed in the mounting groove 1011.

[0025] Preferably, the upper and lower side bars of the rectangular holding frame 201 are provided with a slide groove 2011 extending through the length direction, and the bottom side of the slide groove 2011 is provided with an auxiliary slide groove 2013 (such as Figure 8 As shown), a through hole 2012 is provided at one end of the slide groove 2011; The cleaning mechanism further includes a longitudinal slide bar 204, a counterweight 2042 and a rotating shaft 206. The longitudinal slide bar 204 is symmetrically arranged at two locations, and the two longitudinal slide bars 204 correspond to the two slide grooves 2011 and penetrate and slide in cooperation. A counterweight 2042 is welded at the middle position of the longitudinal slide bar 204 on the side facing the through hole 2012, and the counterweight 2042 slides in cooperation with the slide groove 2011. When the longitudinally arranged sliding rod 204 slides towards the through hole 2012, the counterweight block 2042 is in through fit with the through hole 2012. A positioning slider 2043 is welded to the bottom side of the middle part of the longitudinally arranged sliding rod 204, and the positioning slider 2043 is in sliding fit with the auxiliary sliding groove 2013; Two rotating shafts 206 are symmetrically and rotatably installed at both ends of the longitudinally arranged sliding rod 204.

[0026] Preferably, a limiting plate 2061 is welded to the end of the rotating shaft 206 away from the longitudinally arranged sliding rod 204; On the side of the two upper limiting plates 2061背离 the rotating shaft 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 in through insertion fit with the corresponding limiting plate 2061 on the lower side. The cleaning sponge 207 is limited between the two limiting plates 2061 corresponding to the upper and lower positions; 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 abutting contact with the permanent magnet array 202 and the electromagnet core array 102.

[0027] Preferably, two long strip tracks 103 with a U-shaped cross-section are symmetrically welded to 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.

[0028] Preferably, a horizontal carrier plate 209 is welded to the top end of the rectangular holding frame 201. Two rows of vertically arranged 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 vertically arranged limiting rods 2091 are correspondingly in sliding fit with the U-shaped track grooves on the two upper long strip tracks 103; Two rows of L-shaped limiting rods 203 are symmetrically welded to both sides of the lower side rod of the rectangular holding frame 201. The two rows of L-shaped limiting rods 203 are correspondingly in sliding fit with the U-shaped track grooves on the two lower long strip tracks 103.

[0029] Preferably, the switching drive mechanism includes an incomplete positioning ring 2041, an L-shaped transmission rod 2064, a vertically arranged transmission shaft 2065, and a driving frame 208 with a right trapezoidal structure; Horizontal incomplete positioning rings 2041 are welded to the two protruding parts of the two upper longitudinally arranged sliding rods 204 from the sliding groove 2011. L-shaped transmission rods 2064 are welded to the positions of the two upper rotating shafts 206 close to the longitudinally arranged sliding rod 204. The top end part of the L-shaped transmission rod 2064 is in sliding fit with the corresponding incomplete positioning ring 2041, and an arc-shaped spring is sleeved on the part of the incomplete positioning ring 2041 between the L-shaped transmission rod 2064 and the longitudinally arranged sliding rod 204; The top of the L-shaped transmission rod 2064 is welded with a vertical transmission shaft 2065, and two driving frames 208 are symmetrically welded on the upper side rod of the rectangular holding frame 201 above the slide groove 2011. In the initial state, the vertical transmission shaft 2065 is in contact with the inclined side rod of the driving frame 208 (refer to Figure 7 ); The longitudinal slide bar 204 is positioned on the slide slot 2011 at an end away from the through hole 2012 in an idle state. A positioning bolt 205 is screwed through the bottom of one end of the lower rod of the rectangular holding frame 201 (see Figure 6 ), the top end of the positioning bolt 205 abuts against the lower longitudinal slide bar 204 in an idle state to tighten and position the lower longitudinal slide bar 204; When cleaning the dust on the electromagnetic 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 to a use state that is perpendicular to and in compression contact with the permanent magnet array 202 and the electromagnetic core array 102. In this state, when the rotor assembly 2 slides along the four long rails 103, the two longitudinal slide bars 204, the two counterweights 2042 and the two cleaning sponges 207 can be moved from a stationary state. The inertial impact force generated when the rotor assembly 2 switches to a moving state or switches from a moving state to a stationary state drives the rotor assembly 2 to slide back and forth along the two slide grooves 2011, and wipes and cleans the dust accumulated on the opposite side surfaces of the electromagnetic core array 102 and the permanent magnet array 202. In this way, through the two longitudinal slide bars 204 and the two counterweights 2042, the two cleaning sponges 207 can utilize the inertial impact force generated when the rotor assembly 2 switches between moving and stationary during the sliding operation to wipe the dust accumulated on the electromagnetic core array 102 and the permanent magnet array 202. The row 202 is wiped and cleaned, which saves the trouble of additional manual effort to implement sliding drive for the two cleaning sponges 207 compared to the prior art, and also saves the need to configure additional drive motors for the two cleaning sponges 207. It is easy to operate and use, which helps to indirectly reduce the overall power consumption and cost of the linear motor module; because in the initial state, the vertical transmission shaft 2065 is in contact with the inclined side rod of the driving frame 208, and then in the above process, when the longitudinal slide bar 204 is driven to slide toward the perforation 2012 When the driving frame 208 is in motion, 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 under the blocking and pushing of the inclined side rods of the driving frame 208, and drive the rotating shaft 206 and the cleaning sponge 207 to rotate in the same direction, so as to switch the cleaning sponge 207 from an idle state in which the cleaning sponge 207 is parallel and separated from the electromagnetic core array 102 and the permanent magnet array 202 to a use state in which the cleaning sponge 207 is in vertical contact with the electromagnetic core array 102 and the permanent magnet array 202; When the L-shaped transmission rod 2064 is driven to slide away from the rectangular holding frame 201, it compresses the arc spring sleeved on the incomplete positioning ring 2041. When the cleaning operation is completed and the longitudinal slide bar 204 is slid back to the idle state, the vertical transmission shaft 2065 is separated from the horizontal side rod of the driving frame 208. At this time, the longitudinal slide bar 204 loses the pushing and holding force from the horizontal side rod and can be pushed back by the arc spring on the incomplete positioning ring 2041 to the initial state of contact with the tail end of the inclined side rod of the driving frame 208 (refer to Figure 6 and Figure 7 ), and in conjunction with this, the cleaning sponge 207 is driven to swing to an idle state in which it is parallel and separated from the electromagnetic core array 102 and the permanent magnet array 202; The arc spring on the incomplete positioning ring 2041 can continuously push the cleaning sponge 207 to keep it in a state of being parallel and separated from the electromagnetic core array 102 and the permanent magnet array 202 in an idle state; in an idle state, the cleaning sponge 207 is kept parallel and separated from the electromagnetic core array 102 and the permanent magnet array 202, and two vertical ventilation slots 105 are formed between the permanent magnet array 202 and the electromagnetic core array 102 (refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 ), the two vertical ventilation slots 105 can ensure that the heat dissipation channel 106 between the electromagnetic core array 102 and the permanent magnet array 202 is unobstructed, so as to prevent the cleaning sponge 207 from being in a state of vertically abutting against the electromagnetic core array 102 and the permanent magnet array 202 for a long time in an idle state, thereby blocking the heat dissipation channel 106 and affecting the normal and effective heat dissipation of the electromagnetic core array 102 and the permanent magnet array 202; 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 use the inertial impact force of the rotor assembly 2 to swing and switch between the idle state and the use state, 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 electromagnetic core array 102 and the permanent magnet array 202, and indirectly improve the cleaning operation efficiency; In the above process, when the cleaning sponge 207 is driven to a vertical state, the vertical transmission shaft 2065 is away 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, so that the vertical transmission shaft 2065 can 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 continue to slide back and forth relying on the horizontal side rod of the rectangular holding frame 201. When the vertical transmission shaft 2065 continues to slide relying on the horizontal side rod, it can be The horizontal side rods of the holding frame 201 block the state of being far away from the upper side rods of the rectangular holding frame 201 and keep the cleaning sponge 207 in a state of pressing contact with the electromagnetic core array 102 and the permanent magnet array 202, so that the cleaning sponge 207 can effectively wipe and clean the electromagnetic core array 102 and the permanent magnet array 202 when sliding back and forth along the slide groove 2011. This saves the trouble of manually positioning the cleaning sponge 207 to keep it in a use state during each cleaning operation, which helps to further simplify the operation steps of the cleaning operation and further improve the efficiency of the cleaning operation. In the idle state, the cleaning sponge 207 can be fixed at the end of the heat dissipation channel 106 away from the through-hole 2012 by the positioning bolt 205 to tighten the longitudinal slide rod 204. Such a setting can prevent the cleaning sponge 207 from lacking positioning and continuously sliding back and forth along the heat dissipation channel 106 under the action of the inertial impact force when the rotor assembly 2 is running, causing cutting interference to the magnetic lines of force and magnetic flux lines generated by the permanent magnet array 202 and the electromagnetic core array 102, reducing the thrust applied to the rotor assembly 2 when the magnetic lines of force and magnetic flux lines interact with each other, and affecting the output power of the rotor assembly 2.

[0030] Preferably, a limiting ring 2066 is welded and sleeved on the rotating shaft 206 at a position close to the longitudinal sliding bar 204, a limiting plate 2063 is fixed to one end of the rotating shaft 206 away from the limiting plate 2061, the limiting ring 2066 abuts against one end of the longitudinal sliding bar 204 away from the limiting plate 2061, and the limiting plate 2063 abuts against one end of the longitudinal sliding bar 204 close to the limiting plate 2061; The limiting ring 2066 on the bottom rotating shaft 206 is locked and fixed to the rotating shaft 206 by bolts; When disassembling and replacing the cleaning sponge 207, it is necessary to first loosen and remove the limit ring 2066 on the bottom shaft 206, and push the bottom shaft 206 and the limit plate 2061 thereon upward. When the bottom shaft 206 is pushed upward, the limit plate 2061 thereon temporarily compresses the cleaning sponge 207 and pulls it out from the bottom longitudinal slide bar 204. After the bottom shaft 206 is pulled out from the bottom longitudinal slide bar 204, the bottom longitudinal slide bar 204 is pushed away from directly under the bottom shaft 206, and then the bottom shaft 206 and the limit plate 2061 thereon and the two positioning rods 2062 are slid down and pulled out, and finally the cleaning sponge 207 is extracted and separated from the two positioning rods 2062 and the new cleaning sponge 207 is re-inserted on the two positioning rods 2062 to complete the replacement of the cleaning sponge 207.

[0031] Preferably, it also includes a long strip base 3, and two vertical support plates 301 are symmetrically welded on the top sides of the two end portions of the long strip base 3, and the top ends of the two vertical support plates 301 are respectively welded and fixed to the connecting frame 104; The long strip base 3 is fixedly mounted on the machine platform or the frame by bolts, so that the installation position of the linear motor module can be adjusted as needed.

[0032] The working principle of this embodiment is as follows: the top end of the positioning bolt 205 is in contact with the longitudinal slide bar 204 on the lower side in the idle state, so as to tighten and position the lower longitudinal slide bar 204. When cleaning the dust on the electromagnetic core array 102 and the permanent magnet array 202, the positioning bolt 205 needs to be rotated to loosen the longitudinal slide bar 204 on the lower side, and the cleaning sponge 207 needs to be swung and switched to a use state that is perpendicular to and in compression contact with the permanent magnet array 202 and the electromagnetic 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 to slide back and forth along the two slide grooves 2011 by the inertial impact force generated when the rotor assembly 2 slides along the four long rails 103, switching from a static state to a moving state or from a moving state to a static state, so as to wipe and clean the dust attached to and accumulated on the opposite side surfaces of the electromagnetic core array 102 and the permanent magnet array 202; Since in the initial state, the vertical transmission shaft 2065 is in contact with the inclined side rod of the driving frame 208, and in the above process, when the longitudinal slide bar 204 is driven to slide toward 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 the 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 of being parallel and separated from the electromagnetic core array 102 and the permanent magnet array 202 to the use state of being perpendicular to the electromagnetic core array 102 and the permanent magnet array 202; In the above process, when the cleaning sponge 207 is driven to a vertical state, the vertical transmission shaft 2065 is away 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 a 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 in contact with the horizontal side rod of the rectangular holding frame 201 and continue to slide back and forth relying on the horizontal side rod of the rectangular holding frame 201. When the vertical transmission shaft 2065 continues to slide relying on the horizontal side rod, it can be blocked by the horizontal side rod of the rectangular holding frame 201 and limited to a state away from the upper side rod of the rectangular holding frame 201 and the cleaning sponge 207 is continuously kept in a state of pressing and contacting with the electromagnetic core array 102 and the permanent magnet array 202, so that the cleaning sponge 207 can continue to effectively wipe and clean the electromagnetic core array 102 and the permanent magnet array 202 when sliding back and forth along the slide groove 2011; When the L-shaped transmission rod 2064 is driven to slide away from the rectangular holding frame 201, it compresses the arc spring sleeved on the incomplete positioning ring 2041. When the cleaning operation is completed and the longitudinal slide bar 204 is slid back to the idle state, the vertical transmission shaft 2065 is separated from the horizontal side rod of the driving frame 208. At this time, the longitudinal slide bar 204 loses the pushing and holding force from the horizontal side rod and can be pushed back by the arc spring on the incomplete positioning ring 2041 to the initial state of contact with the tail end of the inclined side rod of the driving frame 208 (refer to Figure 6 and Figure 7 ), and in conjunction with this, the cleaning sponge 207 is driven to swing to an idle state in which it is parallel and separated from the electromagnetic core array 102 and the permanent magnet array 202; the arc spring on the incomplete positioning ring 2041 can continuously push the cleaning sponge 207 in an idle state in which it is parallel and separated from the electromagnetic core array 102 and the permanent magnet array 202.
