The development trend and direction of the equipment are high speed, high precision, composite, intelligent, open, parallel driving, networking, polarizing and greening. The linear motor and the direct drive technology improve the production efficiency of electronic production equipment by the characteristics of low moment of inertia, high acceleration, high positioning precision and high rigidity, meet the increasing production requirements from wafers to integrated circuits and PCB assembly, and are widely applied to the fields of high-precision equipment such as 3C electronics, automatic production equipment, precision numerical control machine tools and the like.

The automatic transmission line (loop) system of the linear motor generally has two structures of a moving coil type and a moving magnet type. The moving coil type structure is characterized in that a primary stator coil moves, a secondary permanent magnet is laid on a rail as a stator, power supply and control are simple, contact (sliding contact) power supply is generally adopted, a driver is located on a rotor, independent control is easily performed on multiple rotors, and cost is low. However, the contact (sliding contact) power supply is easy to generate electric sparks and powder, is difficult to maintain, has low operation speed, is difficult to meet the requirements of production technology, is difficult to protect the stator permanent magnet and the like, is generally used in the field of low-end transmission lines with low requirements on environment and performance, is not allowed to be applied to complex environments such as no spark, no dust, explosion prevention and the like and high-speed, high-precision, high-requirement and medium-high-end occasions, and has extremely limited application fields.

The linear motor has the advantages that the primary coil is electrified for a short time, the electric density can be increased, the size of the linear motor is reduced, the secondary permanent magnet serving as a rotor has small self weight, the secondary permanent magnet is easy to protect, and power supply is not needed. However, the stator coil needs to be supplied with power in sections, and the switching device needs to be supplied with power in sections according to the number of the unit stators. Common segmental power supply switching devices comprise power devices such as IGBTs, thyristors and solid-state relays or electronic switching modes of power switches, and electromagnetic and mechanical switching modes such as contactors. The quantity of the change-over switches and drivers (power modules) is large, a large number of position detection sensors, special trigger protection circuits, upper computers and other processing devices are required to be arranged along a track, the number of intermediate links is large, stator primary coils which are not coupled with a rotor (equivalent to the abnormal working state that the rotor is drawn out by a rotating motor) need to be pre-electrified in advance, the current of the pre-electrified coils is 2-3 times larger than that of the normally coupled stator coils, and the defects of large electric energy loss (proportional to the square of the current of the pre-electrified coils), complex circuit, high cost, malfunction of sensors or contactors, unreliable switching and the like are caused. In order to accurately control a plurality of rotors, the length of a unit stator in the motion direction is short and is generally 1/2 to 1 time of the length of the rotor, so that the number of drivers (power modules), position sensors and cables is large, the number of the unit stators is large, the number of the drivers (power modules) and the number of the position sensors are large, a segmented power supply switching control system is extremely complex, the problem of synchronous control of a plurality of drivers (power modules) for simultaneously controlling one rotor needs to be solved, the reliability of the whole system is greatly related to whether the segmented power supply system is mature and reliable, and the engineering implementation difficulty is large. The construction cost of the whole system is increased sharply, the debugging of the control system is difficult, the debugging period is long (generally 2 to 3 months), the use and maintenance cost is high, the reliability of the system is reduced, and the like, and the whole system is paralyzed when any one position sensor, unit coil and driver (power module) on an operation line (track) is out of order or fails. In the application occasions of the automatic transmission lines, most linear motors run horizontally instead of vertically, the load is light, the required thrust is very small, the benefit of increasing the force density caused by short-time energization of a plurality of primary coils is not obvious in practice, but the cost of the whole system is probably 3 to 5 times of that of a moving coil type. Generally, the method is widely applied to the field of high-precision equipment with higher requirements on environment and performance.

In addition, not only automatic transmission line occasion, also there is similar removal power supply problem in a plurality of trades such as workshop, pier, railway, commodity circulation, storage, wind-powered electricity generation, radar, basic station, space flight, naval vessel (such as revolving stage, driving, mobile station, manipulator, stacker), the occasion, generally use brush sliding contact power supply in a large number, or adopt the conducting ring (a sealed rotatory conducting ring, also sliding contact power supply principle, and is small in size, capacity, with high costs, short service life, often change, it is multi-purpose in signal, undercurrent conduction occasion) or be similar to above-mentioned complicated power supply modes such as stator segmentation power supply, how to make removal power supply as most infrastructure (equipment) more high-efficient, more reliable, more convenient, lower cost also is the key technological problem who awaits the solution urgently.

In fig. 15-a, B, the secondary is a reaction plate, generally made of metal or alloy material such as steel, iron, aluminum, copper, etc., and the mover 6 is primarily a coil with an iron core to constitute a metal (steel, aluminum, copper, etc.) secondary linear induction motor; in fig. 15-B, the secondary stage is a reaction plate with a composite layer 4 on the surface, the composite layer is made of metal materials such as copper, aluminum, etc. or alloy layers thereof, and the primary stage of the mover 6 is a linear induction motor with a core coil, thereby forming a composite secondary linear induction motor; in fig. 15-C, the secondary is a slotted or unslotted iron core, and the primary of the mover 6 is a permanent magnet linear motor with a permanent magnet coil simultaneously provided with an iron core and arranged with a gap between the secondary and the primary to form a switch flux linkage permanent magnet linear motor. In fig. 15-C, the primary of the mover 6 may also be a switched reluctance linear motor formed by arranging a gap between a core coil with a core and a slotted or unslotted core of the secondary; in fig. 15-D, the upper diagram shows a conjugated primary double-sided linear motor formed by conjugated primary and U-shaped primary coils, and the lower diagram shows a conjugated secondary double-sided linear motor formed by conjugated secondary and U-shaped primary coils. In addition, there are also many types of non-permanent magnet linear motors, such as three-sided, four-sided, etc. polygonal types, and arc-shaped types. Simple and reliable structure, no need of protection, low cost and the like. The principle structures of the figures 1 to 13 are also suitable for the non-permanent magnet secondary linear motor.

The linear motor needs to work normally, a certain working air gap (gap) and a certain coupling area need to be kept between a stator and a rotor of the linear motor, electromagnetic thrust is generated between the rotor and the stator in the movement direction, and normal force is generated in the air gap (gap) direction (normal direction), especially for a single-side-band iron core linear motor, the normal force may be 5 to 10 times of the electromagnetic thrust (for a double-side linear motor, when the working air gaps at two sides are the same, the normal force between the rotor and the stator can be mutually offset). Therefore, at least two dimensions of a three-dimensional space between the moving stator and the stator are limited (except for the moving direction) and a guide positioning support component is arranged, and the positioning of the transport body is mainly realized by rolling and/or sliding components aiming at the support between the moving stator and the stator, and can also be realized by floating components such as pneumatic, magnetic suspension and the like. According to the type of the moving stator, namely one side or two sides, and the permanent magnet or the non-permanent magnet, the moving stator comprehensively considers various factors such as the arrangement mode of the transmission vehicle, the stress condition, the performance and the cost requirement, the relative positions of the stator, the guide rail and the wireless power supply transmitting part, for example, whether the stator and the guide rail are on the same side, and the like. The dynamic stator positioning topological structure has various schemes, and has advantages and disadvantages, such as double-track positioning, high positioning precision and high track cost; the monorail positioning has simple structure and low cost, but has high requirement on the strength of the carrier plate of the carrier; the common guide rail has various types such as a linear guide rail, a V-shaped guide rail, an inclined plane (plane) guide rail and the like, and corresponding sliding and rolling parts have various types such as a sliding block (guide shoe), a V-shaped wheel, a flat guide wheel and the like, and are selected according to specific requirements in practical application.

In the above-mentioned structure diagrams of fig. 1 to 21, the driving controller 12, the wireless communication receiving device (communication circuit board), the power circuit board, etc. as the motion electric control component may be flexibly disposed above and/or below the configuration board (a) 10 and/or the lower configuration board 9 of the transportation body according to the requirement, or may be disposed inside and/or outside the configuration board (B) 11 of the transportation body. The driving controller 12, the wireless communication receiving device, the power circuit board and the like may be integrated into one unit or integrated into a whole. In addition, the stator secondary permanent magnet or the secondary reaction plate or the secondary iron core can be arranged vertically, parallel or obliquely at a certain angle with the transportation track.

The structural diagrams of fig. 1 to 21 are only illustrated in terms of a principle topology structure by using horizontal or vertical or specific inclination arrangement, and in fact, all the structural diagrams of fig. 1 to 21 may be arranged by rotating clockwise or counterclockwise by any angle (for example, 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 135 degrees, 150 degrees, 180 degrees, etc.).

The wireless transmission power supply system includes a wireless power supply transmitting part 7 and a wireless power supply receiving part 8, and may be an inductive wireless transmission power supply system, such as a common electromagnetic induction type, an electric field induction type, and other wireless transmission power supply systems, an electromagnetic wave type, a resonance type, and other wireless transmission power supply systems, or a reaction type, a coupling type, an electromechanical conversion type, a mechanical transmission type, and other novel wireless transmission power supply systems; the wireless communication system comprises a wireless communication transmitting device and a wireless communication receiving device, such as common WiFi, 232/485 and Modbus systems, and can also be novel wireless communication systems of 5G, 6G and the like.

The transmission line can also adopt a scheme of simultaneously supplying power by wireless power supply and a storage battery (capacitor) and independently supplying power by the storage battery (capacitor).

Scheme for wireless power supply of rotor and simultaneous power supply of storage battery (capacitor). On the basis of fig. 1-30, a storage battery and/or a capacitor is additionally arranged on the rotor, the wireless power supply transmitting part 7 can be arranged along the whole transmission line transportation track, and can also be arranged in a concentrated way at a section designated by the transmission line as a charging section so as to reduce the line cost. The scheme has three power supply modes: 1) The wireless power supply transmitting part 7, the wireless power supply receiving part 8 and the storage battery (capacitor) simultaneously supply power to the driver, the mover and the auxiliary device on the mover; 2) The driver, the mover and the auxiliary device on the mover are powered by a storage battery (capacitor), and the wireless power supply transmitting part 7 and the wireless power supply receiving part 8 are only used for wirelessly charging the storage battery (capacitor); 3) The wireless power supply transmitting unit 7 and the wireless power supply receiving unit 8 supply power to the driver, the mover, and the auxiliary device on the mover, and wirelessly charge a storage battery (capacitor) that serves only as a backup (backup) power supply. Preferably, the battery (capacitor) management system monitors that the electric energy (voltage) of the storage battery (capacitor) on the rotor is insufficient or close to a set value, the wireless power supply system is started, the storage battery (capacitor) is wirelessly charged during the period of non-rapid acceleration (uniform speed) and parking clearance, and the originally wasted huge energy generated in the parking braking and deceleration processes is fully utilized and recycled to charge the storage battery (which is also a great characteristic and advantage of the storage battery scheme), so that the power, the volume and the cost of the wireless power supply device and the storage battery (capacitor) can be reduced to the greatest extent. The storage battery (capacitor) can timely and quickly supplement the electric quantity on the premise of not influencing the production progress, the transportation body can be ensured to continuously operate for 24 hours except for maintenance, and the working efficiency is obviously improved. When power failure or wireless power supply device breaks down, the storage battery (capacitor) can still ensure the normal operation of a production line, and the reliability and stability of power supply are effectively guaranteed (increased). The scheme can be generally used in application occasions with higher requirements on reliability, stability (safety), yield and yield.

The scheme of independent power supply of the rotor storage battery (capacitor) and automatic/manual replacement of the standby (standby charging) storage battery in parking is adopted. The scheme adopts a storage battery (capacitor) to supply power to a transmission line without adopting wireless and wired (sliding contact) power supply, namely, a wireless power supply sending part 7 and a wireless power supply receiving part 8 in figures 1-30 are deleted, the storage battery (capacitor) is arranged on a rotor, a driver, a primary coil and an auxiliary device on the rotor are supplied with power by the storage battery (capacitor), a certain number of charging piles and standby (charging) storage batteries are arranged nearby near the transmission line, and when the storage battery (capacitor) on the rotor is monitored by a battery management system to be insufficient in electric energy (voltage) or close to a set value, the storage battery can be replaced manually or the insufficient storage battery (charging pile) is moved out and the standby (charging) storage battery is replaced by a special mechanism of an automatic battery replacement system (device) under a rotor parking state carrying the storage battery (capacitor). The movable cell transportation body can be further provided with a rail-changing connection (branch) section (such as the rail-changing connection section in fig. 10 and fig. 11), the replacement of the whole movable cell transportation body including the standby movable cell, the standby (standby charging) storage battery, the standby primary coil and the standby driver can be rapidly completed by utilizing the synchronous displacement (transposition) of the rail-changing connection section, and the power-shortage storage battery on the replaced movable cell transportation body can be automatically or manually (in a power-off state) connected and powered on to charge through a special charging plug (socket) and a special charging socket (plug) on the charging pile. The scheme is simple, the cost is low, but the storage battery is replaced in the parking mode, certain time can be consumed, and the utilization rate of the rotor transport body is reduced to a certain extent.

In the situation that the requirements of cost, reliability and the like are more strict and spark and dust are not allowed to be generated, non-sliding contact power supply schemes such as a traveling transformer, a follow-up power conversion ring (including a follow-up transformer and a follow-up generator) and the like can be adopted.

Taking a common three-phase core type transformer as an example, three core legs of an E-shaped iron core of the primary part of the transformer 22-A can be respectively sleeved with A, B and C three-phase primary coils, and three core legs of an E-shaped iron core of the secondary part can be correspondingly respectively sleeved with A ', B ' and C ' three-phase secondary coils, so that a basic structure diagram of the three-phase traveling transformer is formed, and the rest parts are not described again. In addition, the primary part and the secondary part of the single-phase or multi-phase traveling transformer can be arranged interchangeably, and are not described again.

The power supply scheme of the traveling transformer is applied to transmission lines of figures 1-30, only the primary part of the traveling transformer is replaced by the wireless power supply transmitting part 7 and is arranged along a track or a foundation, the secondary part of the traveling transformer is replaced by the wireless power supply receiving part 8 and is connected with the transportation body and moves along the longitudinal direction (the direction perpendicular to the paper surface in figure 22) along with the transportation body, and the positioning of the secondary part of the traveling transformer in the transverse direction and the normal direction can be independently arranged and can also be realized by utilizing a supporting (positioning) part of the transportation body. The power supply scheme of the traveling transformer is simple in structure, a large and complex wireless power supply high-frequency (generally 50 to 90kHz) switching power supply device is not needed, a small-gap multi-turn coil with an iron core forms a good closed magnetic circuit of the transformer (namely an open-ended or a sun-shaped closed magnetic circuit), the power supply efficiency and reliability are far higher than those of a large-open-ended hollow single-turn cable (E-shaped, U-shaped or C-shaped) semi-open magnetic circuit, the electromagnetic compatibility and noise control of the power supply of the power frequency (50 Hz) of the traveling transformer are also obviously better than those of a high-frequency power supply device of dozens of kHz of the power supply of the large-power high-frequency power supply device of more than 1kW, the electromagnetic interference and noise are large, and the electromagnetic interference and noise are caused to the surrounding environment, personnel operation and normal alternating current, the electromagnetic interference and the noise are difficult to use in a quiet environment, the cost is controllable, the traveling transformer is real and durable, the wireless power supply device is particularly suitable for complex environments (places) with high reliability and high requirements in all aspects.

In the figure, N rotors (transportation bodies) are provided with N secondary parts, primary parts arranged along a track can be equivalent to #1,2#,3#, \8230, # N sections of inductance coil units, N primary parts (inductance coil units) coupled with the rotor secondary parts and N secondary parts form N traveling transformers, secondary coils of the traveling transformers are connected with drivers on the transportation bodies to provide power, N-N primary parts not coupled with the rotor secondary parts can be regarded as inductance coils, and the N traveling transformers and the (N-N) uncoupled inductance coils form a series circuit and are connected with a power supply voltage U. In a similar way, a parallel or series-parallel hybrid circuit can be formed, and each coil can also be connected into a power supply source in a segmented power supply mode. The power supply scheme and the wiring are simple and flexible, and a series power supply mode can be generally preferred.

The traveling transformer is provided with N sections of primary parts, wherein N is more than or equal to 1; when N =1, the whole primary section of the traveling transformer is arranged on the moving path of the moving body and matched with the secondary part of the traveling transformer, the primary coil of the whole primary section is connected with a power supply, when N is larger than or equal to 2, the primary section of the traveling transformer is arranged on the moving path of the moving body and matched with the secondary part of the traveling transformer, and the primary coils of the N primary sections are sequentially connected in series or in parallel with the power supply.

A power supply scheme of a follow-up power ring (including a follow-up transformer and a follow-up generator) is shown in fig. 24, wherein the follow-up power ring is composed of a static part 35 and a follow-up part 36, and is provided with an input end and an output end respectively. The servo rotating ring is generally disposed at the geometric center (geometric center) of the transmission line (loop line), the output end of the servo rotating ring is connected to the drivers on the plurality of transportation bodies 26 through a power supply cable (hereinafter referred to as cable), and the input end of the servo rotating ring is connected to a power supply. The cable is laid with multiple mode: (1) use of non-retractable cables. Enough margin (larger than the longest towing distance) is reserved for the length of the common cable, the cable naturally sags or bends (forms an arc shape), so that the transportation body can freely move along the cable within a certain operation (travel) range, and when the cable is towed to a certain extent in a stretching way, the cable drives the rotation part to freely rotate along with the rotating ring, thereby realizing the whole-course free operation of the transportation body cable, and the cable is generally used for a transmission line with a small length-width ratio (such as a ring type); and (2) adopting a shrinkable cable. There are natural contraction cables and automatic contraction cables. The natural contraction cable is a common cable with a spiral spring, namely the cable is wound into a spiral spring shape by a circle (the earphone connecting wire of the common fixed telephone adopts the spiral cable), and the cable has elasticity and realizes the natural contraction of the cable within a certain range; the automatic retractable cable is based on the principle of automatic take-up (capable of removing a limiting device) similar to an automatic retractable tape measure and an automatic retractable (automobile/airplane) safety belt, and mainly comprises a take-up pulley (a wire winding wheel) and a spring connected with the take-up pulley, the cable is placed in the automatic take-up device (wound on the take-up pulley), the automatic take-up device is generally arranged on a transport body and can also be arranged on a rotating part of a rotating ring, one end of the cable is connected with a driver, the other end of the cable is connected with the output end of the rotating ring, through the automatic take-up device, when the distance between the transport body and the rotating ring is increased, the cable is stretched by using the traction force of the transport body to overcome the spring force, and when the distance is decreased, the cable is automatically recovered (accommodated) by using the resilience force of the spring, so that the automatic take-up and pay-off of the cable in the whole process of the operation of multiple transport bodies are realized, the automatic retractable cable is suitable for long and narrow transmission lines with small difference in length and width, and is especially suitable for the high-density operation of the transport bodies and wider application occasions; as a preferred scheme, the power output with the power conversion ring is connected with the transport body (driver) through an automatic contraction cable. The power supply structure along with the rotating electricity ring is simple, the power supply is stable and reliable during the movement of each transporter, and the power supply device is particularly suitable for the fields of non-branch and non-connection transmission lines, mobile power equipment and the like.

The rotor-following electric ring can also be made into a multi-layer rotor-following electric ring which is formed by coaxially stacking, the number of rotor-following electric rings is the same as that of the rotor, the rotor-following part of each layer of the rotor-following electric ring is correspondingly connected with a different rotor, and the connecting lines of the rotors are completely independent in space and do not interfere with each other. Taking 4 rotors in a continuous horizontal (circular ring or runway-shaped) loop line as an example, a plurality of layers of rotating-following electric rings are stacked up and down layer by layer in the vertical (height) direction and are arranged at the geometric center (center) of the loop line, and the rotating-following parts of the 1,2, 3 and 4 layers of rotating-following electric rings are sequentially and correspondingly connected with the 1#, 2#,3# and 4# rotors from bottom to top, so that the independent motion (control) of each rotor can be realized. Or a plurality of adjacent movers (for example, 2 adjacent movers) can share the same layer of the following rotating electric ring, so that the layer number of the following rotating electric ring is reduced.

The power-following ring is a power-following transformer power supply scheme, and fig. 25 is a schematic diagram of a single-phase power-following transformer principle. The basic working principle of the converter is the same as that of the above-mentioned traveling transformer, but the former is set up in a rotating gap, and the latter is set up in a parallel moving gap. The following part of the following-up transformer is the part where the secondary coil of the following-up transformer is located, the output end of the following-up transformer is the output end of the secondary coil of the following-up transformer, the static part of the following-up transformer is the part where the primary coil of the following-up transformer is located, and the input end of the following-up transformer is the input end of the primary coil (power supply) of the following-up transformer.

In fig. 25, the middle iron core 61 itself serves as a middle rotating shaft, the upper iron core 53 is connected to the bearing seat 52, the primary coil 56 and the bearing 51 are sleeved on the middle iron core 61, the bearing seat 52 is arranged in cooperation with the bearing 31, the secondary coil 57 is arranged in rotation and connected to the upper iron core 53 through the retainer 54, or directly connected to the bearing seat 52 or located between the upper and lower two bearing seats 52, the secondary coil 57 is respectively in clearance fit with the primary coil 56 and the outer iron core 55, so that the upper iron core 53 and the secondary coil 57 can rotate around the middle iron core 61 (middle shaft), the rotatable upper iron core 53 is located between or above the statically arranged outer iron core 55 and the middle iron core 61, and the three are in clearance fit to form a minimum closed magnetic flux path (loop); in order to reduce the rotating clearance between the rotating part and the static part as much as possible and reduce the magnetic resistance of the magnetic circuit to the maximum extent, the outgoing line of the output end of the secondary side coil can be led out through the through holes of the upper iron core 53 and the bearing seat 52 (drilling holes), and the area of the upper iron core is reasonably designed to drill a plurality of small threading holes on the upper iron core, so that the main magnetic circuit cannot be influenced; in principle, the upper core 53 may be disposed between the stationary outer core 55 and the middle core 61, or may be disposed above the outer core 55. If the upper iron core 53 is disposed above, there is a large inherent normal magnetic attraction between the upper iron core 53 and the outer iron core 55 and the middle iron core 61 which are statically disposed in the same closed main magnetic path, which may cause a series of problems of structural strength, positioning and guiding, etc., so in fig. 25, the upper iron core 53 is disposed between the outer iron core 55 and the middle iron core 61, and the normal magnetic force direction is in the left-right (horizontal) direction, so that the normal forces can be mutually offset and balanced by using the axial (left-right) symmetrical structural characteristics, the structure is simple, the volume of the whole device is smaller, and the cost is low. When the primary coil 56 is supplied with an ac power, a magnetic flux loop is formed between the middle core 61 and the upper and

outer cores

53 and 55 according to the law of electromagnetic induction to generate an alternating magnetic flux, and the alternating magnetic flux passes through the primary coil 56 and the secondary coil 57 at the same time, thereby inducing a voltage in the secondary coil 57.

The cross sections of the upper iron core 53, the outer iron core 55 and the middle iron core 61 can be triangular, quadrangular, pentagonal or polygonal, and can also be cylindrical, circular or cup-shaped, such as the inner and outer cylindrical middle iron cores 61 and the outer iron cores 55; when the cross sections of the outer iron core 55 and the middle iron core 61 are quadrangular (rectangular) or polygonal, the upper iron core 53 should be arranged in a disc (circular ring) shape or a cylinder shape in order to ensure the continuity of the magnetic flux path, and the structure can be taken as a preferred embodiment, so that the advantages that the lamination structure and the processing and assembling process of the existing transformer can be fully utilized, and the structure is simpler and more practical; or conversely, when the upper core 53 has a quadrangular (rectangular) or polygonal cross section, the outer core 55 and the middle core 61 are formed in a cylindrical (cylindrical) shape.
