Description

Technical Field

[0001] The invention relates to an inductive energy transmission device for a linear transport system, a magnetic drive slide having such an inductive energy transmission device, and a linear transport system. Background Art

[0002] In a linear transport system, the slide and the track guide form a linear motor. In this case, the track guide is usually the stator of the linear motor, which has the drive coils. The slide is the rotor of the linear motor, which has magnets. By energizing the drive coils in the track guide, a force is applied to the magnets of the slide, causing the slide to move along the track guide.

[0003] The carriage can have a tool and a carriage controller, which is used to exchange data with the controller of the rail-type guide. In order to be able to wirelessly operate these electrical consumers (hereinafter also referred to as loads) on the carriage, energy must be transmitted from the carriage guide to the carriage.

[0004] DE 10 2018 111 715 A1 discloses a linear transport system, which is provided with an inductive energy transmission device between a carriage guide and a carriage that can be moved on the carriage guide. The inductive energy transmission device has an energy transmission coil, which has a primary winding for applying an input voltage, wherein the primary winding extends along the carriage guide. An energy receiving coil of the inductive energy transmission device is provided on each carriage, and the energy receiving coil includes a secondary winding for tapping the output voltage. When the carriage moves along the carriage guide, the energy transmission coil and the energy receiving coil are at least partially opposite to each other, so that energy is transmitted from the energy transmission coil to the energy receiving coil, and then the energy is provided to an electrical device on the carriage. In the linear transport system of DE 10 2018 111 715 A1, in addition to the inductive energy transmission, a contactless data transmission between the carriage guide and the carriage is provided by means of an antenna arranged on the carriage guide or the carriage.

[0005] US10,483,895B2 describes another inductive energy transmission device for a linear transport system, in which the primary winding of the energy transmitting coil is arranged along a track-type guide, and each slide has a secondary winding as an energy receiving coil. The primary winding of the energy transmitting coil and the secondary winding of the energy receiving coil are both planar and arranged so that: when the slide moves along the track-type guide, the secondary winding is substantially aligned with the primary winding, leaving an air gap. Then, the energy transmitted from the primary winding to the secondary winding is provided to the electrical device located on the slide. Summary of the invention

[0006] The object of the invention is to provide an inductive energy transmission device for a linear transport system in which the energy transmitted from the carriage guide to the carriage can be adjusted quickly as required.

[0007] This object is achieved by the independent claim. Advantageous solutions are indicated in the dependent claims.

[0008] In a linear transport system, at least one magnetically driven slide moves along a slide guide having a motor module device, and an inductive energy transmission device is provided, which includes an energy transmitting coil and an energy receiving coil, wherein the energy transmitting coil has a primary winding for applying an input voltage, and the energy receiving coil has a secondary winding for tapping an output voltage. The energy transmitting coil is arranged on the motor module device and extends along the slide guide. The energy receiving coil is arranged on the slide and extends along the slide. When the slide moves along the slide guide, the energy transmitting coil and the energy receiving coil are at least partially opposite to each other so as to transfer energy from the energy transmitting coil to the energy receiving coil. The secondary winding of the energy receiving coil has a control voltage winding part and a load voltage winding part, wherein the control voltage winding part and the load voltage winding part include winding wires separated from each other. The control voltage winding part provides a control voltage for tapping by a slide guide control unit on the slide; the load voltage winding part provides a load voltage for tapping by a load on the slide.

[0009] By dividing the secondary winding of the energy receiving coil into a control voltage winding part and a load voltage winding part, it is possible to supply energy to different electrical consumers on the carriage separately as required, in particular to ensure that the energy supply to the carriage controller is always active and is not affected by the load voltage circuit for supplying energy to the carriage tool. For example, the control voltage winding part can provide a 24V control voltage in open circuit operation, while the load voltage winding part can provide a 48V load voltage in open circuit operation. The separate windings also facilitate the adjustment of the conductor cross section and the number of turns for the load voltage, so that, for example, a significantly higher load voltage can be generated in certain applications, while the control voltage remains unchanged. The load voltage can also be changed quickly separately from the control voltage and can also be switched off independently.

[0010] The cross section of the winding wire forming the control voltage winding portion may be designed to be smaller than the cross section of the winding wire forming the load voltage winding portion.

[0011] By dividing the secondary winding of the energy receiving coil into two windings and by designing the cross section, the control voltage winding part can provide a low-power control voltage for the sensor and / or actuator on the carriage, while the load voltage winding part can provide a high-power load voltage.

[0012] The number of turns of the control voltage winding portion may be lower than the number of turns of the load voltage winding portion.

[0013] Due to the high number of turns in the load voltage winding section, a stable voltage can be obtained over a wider effective load range.

[0014] The energy transmitting coil and the energy receiving coil may each have an axis. When the slide moves along the slide guide, the energy transmitting coil axis of the energy transmitting coil and the energy receiving coil axis of the energy receiving coil are oriented parallel to each other and at least partially opposite to each other. The surface spanned by the primary winding of the energy transmitting coil is parallel to the energy transmitting coil axis of the energy transmitting coil. The surface spanned by the control voltage winding portion and the load voltage winding portion of the secondary winding of the energy receiving coil is perpendicular to the energy receiving coil axis of the energy receiving coil.

[0015] This design ensures a compact structure of the inductive energy transmission device with a flat energy transmitting coil. The control voltage winding part and the load voltage winding part are designed to be perpendicular to the wire axis of the energy receiving coil, thereby improving the utilization of the winding space.

[0016] The cross-sections of the energy transmitting coil bobbin of the energy transmitting coil and the energy receiving coil bobbin of the energy receiving coil may be E-shaped, respectively, with two outer arm ribs and a center rib formed on the bobbin surface, wherein when the slide moves along the slide guide, the E-shaped cross-sections face each other, and the outer arm ribs and the center ribs of the bobbin surface are opposite to each other. The primary winding of the energy transmitting coil is arranged between the first energy transmitting coil outer arm rib and the second energy transmitting coil outer arm rib of the energy transmitting coil bobbin around the energy transmitting coil center rib. The control voltage winding part and the load voltage winding part of the secondary winding of the energy receiving coil are arranged between the first energy receiving coil outer arm rib and the second energy receiving coil outer arm rib of the energy receiving coil bobbin around the energy receiving coil bobbin surface.

[0017] Compared to the primary winding of the energy transmitting coil, which is designed around the center rib of the bobbin, the control voltage winding part and the load voltage winding part of the secondary winding of the energy receiving coil are designed around the outer arm ribs of the bobbin, respectively, so there is twice the winding space. The magnetizing ampere-turns remain unchanged because the magnetic flux through the center rib of the bobbin is higher than the magnetic flux through the outer arm ribs of the bobbin. Due to the larger winding space, the number of turns of the winding can be increased with the same cross-section.

[0018] The energy receiving coil bobbin of the energy receiving coil may have a first energy receiving coil bobbin portion in which the load voltage winding portion is implemented and a second energy receiving coil bobbin portion in which the control voltage winding portion is implemented.

[0019] By dividing the bobbin of the energy receiving coil, the control voltage winding part and the load voltage winding part are respectively implemented in separate bobbin parts, which can simplify the coil structure and facilitate assembly.

[0020] The control voltage winding part and the load voltage winding part of the energy receiving coil may also be arranged alternately.

[0021] The staggered division of the control voltage winding section and the load voltage winding section of the energy receiving coil on the bobbin ensures that the magnetic flux in the bobbin always remains symmetrical. In this way, load differences in the windings do not cause asymmetric and dynamic changes in the magnetic flux through the bobbin.

[0022] The energy receiving coil may include a first energy receiving coil printed circuit board having a first winding conductor, a second energy receiving coil printed circuit board having a second winding conductor, and an energy receiving coil bobbin arranged between the first energy receiving coil printed circuit board and the second energy receiving coil printed circuit board. Then, the first winding conductor of the first energy receiving coil printed circuit board and the second winding conductor of the second energy receiving coil printed circuit board are connected to each other through an electrical connector to form a control voltage winding portion and a load voltage winding portion of a secondary winding of the energy receiving coil.

[0023] In the printed circuit board design of the energy receiving coil, the winding wires are designed on two separate printed circuit boards, which are connected together through an electrical plug-in connection, thereby simplifying the separate design of the control voltage winding part and the load voltage winding part of the secondary winding of the energy receiving coil.

[0024] The cooling device for the control voltage winding part and the load voltage winding part of the secondary winding of the energy receiving coil may be arranged on a side of the energy receiving coil bobbin of the energy receiving coil away from the energy transmitting coil bobbin of the energy transmitting coil.

[0025] In the winding arrangement of the energy receiving coil, one winding side is located outside the voltage transformer formed by the energy transmitting coil and the energy receiving coil of the energy transmission device and is therefore suitable for mounting a heat sink. The heat sink can extend from the carriage housing, for example, so that the cooling fins of the heat sink are located outside the carriage housing in order to be cooled by the travel wind of the carriage.

[0026] A magnetically driven slide for a linear transport system, in which the slide moves along a slide guide having a motor module device, a control voltage winding portion of the secondary winding of an energy receiving coil can be connected to a slide control unit via a first rectifier, and a load voltage winding portion of the secondary winding of the energy receiving coil can be connected to a load via a second rectifier.

[0027] Through this design, independent control voltage circuit and load voltage circuit can be formed on the magnetic drive slide.

[0028] A load voltage circuit switch connected to the carriage control unit may be provided between the load voltage winding part of the secondary winding of the energy receiving coil and the load, wherein the carriage control unit may open the load voltage circuit switch to disconnect the load from the load voltage winding part.

[0029] Since the windings of the energy receiving coil are separated, the control voltage and the load voltage for the carriage can be generated as two independent voltages. In this case, a controller on the carriage, which is powered by the control voltage, can monitor and influence the load voltage with the aid of switches. For example, the load voltage circuit can be disconnected from the load in the event of load fluctuations, thereby preventing the load voltage circuit from overvoltage in the event of a sudden load drop, which could damage the electronics in the load voltage circuit. If necessary, energy can also be saved by disconnecting the load voltage circuit. Local control of the load voltage circuit on the carriage is much faster than first transmitting the current voltage value to the track-type guide via data transmission and then adjusting the energy transmission of the energy transmitting coil by changing the frequency and / or amplitude.

[0030] A first energy store can be connected to the control voltage winding part and a second energy store can be connected to the load voltage winding part, wherein the first energy store and the second energy store are designed to provide temporarily stored electrical energy to the carriage controller and / or the load.

[0031] By tapping off two independent voltages on the carriage, better energy storage can be achieved. This makes it possible to decide in the application, if necessary, by selecting the first or second energy store, whether the control voltage is to be buffered in order to maintain active control for a longer time even in areas where no energy is transmitted, or whether more power is to be supplied to the load voltage circuit for a short time at locations where connected sensors or actuators require higher power. Two independent voltages also help to achieve greater reserves, for example to supply the control voltage for a controller on the carriage.

[0032] Furthermore, a linear transport system can be designed with at least one magnetically driven carriage and a carriage guide having a motor module arrangement, wherein the at least one magnetically driven carriage moves along the carriage guide. The motor module arrangement comprises a plurality of energy transmitting coils and is designed to select at least one energy transmitting coil according to control information and to set energy transmission from the energy transmitting coil to an energy receiving coil on the carriage.

[0033] This allows for a targeted and optimal energy transfer from the motor module assembly to the magnetic drive carriage. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In the drawings, the same features are labeled with the same reference numerals. In addition, for the sake of clarity, not all components are shown in every figure, and not every component has its own reference numeral in every figure.

[0045] In linear transport systems, a magnetically driven slide moves along a slide guide with a motor module. In this case, the motor module and the slide form a linear motor, wherein the motor module has electromagnetic coils, also referred to below as drive coils, and the slides each carry magnets, for example in the form of magnetic plates, which together with the drive coils of the motor module generate a controllable propulsion force. The motor module is also equipped with power electronics and position detection for the slide.

[0046] The slide guide has guide rail elements for the slide, which are arranged on or next to the motor module and are used to define the travel path of the slide. In order to move on the guide rails, the slides each have a guide mechanism. The slide guide can be of any shape, in particular it can form a closed slide travel path. The required geometry, length and radius are determined by the number and / or selection of motor modules and the associated guide rail elements.

[0047] The slide can move freely along the entire travel path defined by the slide guide, i.e. the slide can brake, accelerate, position and apply a constant force when stationary and moving. The slide movement can also be synchronized with other movement processes. In the case of a closed slide travel path, the slide can move endlessly.

[0048] The slides can be moved independently of one another. As a result, the slides can be moved to a predetermined position along the entire travel path or can be moved relative to one another. The slides can be automatically grouped together to form a movement buffer zone from which the moving object can be approached with high dynamics. During continuous movement, groups of slides can be formed which will stop together or approach the processing station with a predetermined speed profile.

[0049] There is basically no limit to the number of slides on a slide guide. The number of slides is determined by the length of the slide guide and can be optimized to the intended application. For position detection by the motor module, the slides each have a position sensor that transmits the slide position signal to the motor module.

[0050] The linear transport system can be designed as a double air-gap linear motor. In this case, the magnets on the carriage surround the drive coils of the motor module on opposite sides. The carriage then absorbs the attractive forces of the magnets on both sides of the motor module and largely compensates for the attractive forces relative to the guide mechanism on the carriage. The guide mechanism of the carriage can then run on the guide rails of the carriage guide with low wear.

[0051] Linear transport systems are extremely versatile and enable very fast material transport. By controlling the carriages accordingly, products can be moved, their distance adjusted and / or their speed reduced or increased. Products can also be clamped, moved, transported and discharged.

[0052] Furthermore, linear transport systems often require manipulation of the product, i.e. lifting, closing, rotating the product, tightening a cap, etc. This can be done either by a processing station on the slide guide or by a tool on the slide. The slide tool can be, for example, a clamp, a push rod, a drill or an alignment device.

[0053] In addition to tools for operating the product, the slide can also be equipped with other types of electrical devices, such as measuring tools for measuring physical variables such as temperature, pressure, current, voltage, acceleration, mass, etc.

[0054] Furthermore, a carriage controller may be provided on the carriage. The carriage controller may be used to exchange data with a controller of the rail guide including the motor module. The purpose of this data exchange may be to transmit status information, such as measurement signals, which are then taken into account when controlling the carriage movement. The purpose of this data exchange may also be to transmit control information for the carriage tool from the rail guide to the carriage. The carriage controller may also be used to autonomously control the tool on the carriage.

[0055] In order to be able to operate the slide tool or the slide controller, the slide needs to be powered. The wireless design is to transmit energy to the slide inductively. The device for this inductive energy transmission includes at least one energy transmitting coil, which has a primary winding extending along the slide guide. Each slide also has at least one energy receiving coil, whose secondary winding extends along the slide. The energy transmitting coil on the slide guide and the energy receiving coil on the slide are arranged in such a way that when the energy receiving coil of the slide is located in the energy transmitting coil area of ​​the slide guide, the energy receiving coil and the energy transmitting coil at least partially overlap. The energy transmitting coil then forms a voltage transformer with the energy receiving coil.

[0056] The controller of the slide guide detects the corresponding movement position of the slide on the slide guide with the help of the position detection system and applies the input voltage to the energy transmitting coil. The energy receiving coil then taps the output voltage and supplies it to the electrical equipment on the slide.

[0057] In order to provide fast on-demand energy supply, the secondary winding of the energy transmitting coil has two winding parts, one is the control voltage winding part and the other is the load voltage winding part, and the two winding parts have separate winding wires. Then, the energy receiving coil provides two independent voltages as output voltages, one is the control voltage for the slider controller to tap; the other is the load voltage for the load on the slider to tap.

[0058] Thus, the slide controller can be powered independently, without being affected by other electrical consumers on the slide. It is also possible to set the voltages for the slide controller and the load independently. The control voltage or the load voltage can be determined by the number of turns of the relevant winding wire. Thus, the load voltage winding part can be designed with a smaller wire cross section and a higher number of turns in order to provide a higher load voltage than the control voltage of the control voltage winding part. For example, the control voltage winding part can provide an open-circuit control voltage of 24 V, while the load voltage winding part provides a load voltage of 48 V in open-circuit operation.

[0059] In the following, a technical solution of an inductive energy transmission device for a linear transport system will be described, in which the secondary winding of the energy transmission coil has two winding conductors separated from each other, one for a control voltage winding part and the other for a load voltage winding part.

[0060] Figure 1 A plan view or a side view of a curved section of a linear transport system 101 is shown, depending on the orientation of the linear transport system in space. As part of a carriage guide 102 of the linear transport system 101, Figure 1 Five motor modules 107 are shown, each of which is provided with a guide element 105. The motor modules 107 are partially designed in different ways, and the figure shows a configuration consisting of a curved motor module, a straight motor module, a 180-degree motor module, a straight motor module and a curved motor module. The guide elements 105 of the motor modules 107 are respectively adapted to the shape of the motor modules, i.e. curved, straight or curved by 180 degrees. The carriage guide 102 of the linear transport system 101 forms a travel path, the trajectory of which lies in a plane.

[0061] The linear transport system 101 has a slide guide control unit 133 connected to the motor module 107 for controlling the operation of the motor module. Figure 1 As shown, the slide guide control unit 133 can be connected to only one motor module 107, and then the other motor modules 107 are connected to the connected motor module 107 through a communication bus, so that signals can be exchanged between the slide guide control unit 133 and different motor modules 107. As an alternative, the slide guide control unit can also be connected to each motor module or multiple motor modules. In addition, the slide guide control unit can also be composed of multiple units arranged in a distributed manner.

[0062] Depending on the application, any number of slides 103 can be arranged on the slide guide 102 of the linear transport system 101. Figure 1 In the section of the slide guide 102 shown, a single slide 103 is guided on the slide guide 102 .

[0063] Figure 2 Display with Figure 1 The motor module 107 of the guide rail element 105 in the embodiment of the present invention is provided, on which the individual slides 103 are guided. Figure 3 show Figure 2 sectional view of the motor module 107 with the guide rail element 105 and the guided slide 103.

[0064] The motor module 107 of the carriage guide 102 and the carriage 103 moving on the carriage guide 102 form a linear motor of the linear transport system 101. The motor modules 107 as stators of the linear motor each include a plurality of pole teeth 109, which are arranged spaced apart from each other along the motor module 107. The pole teeth 109 are generally rod-shaped and oriented transversely to the motor module 107. A drive coil winding 111 is provided on every second pole tooth 109, such as Figure 3 The winding pole teeth 109 form the driving coil of the linear motor.

[0065] like Figure 3 As shown, the slide 103 is substantially symmetrical with respect to the longitudinal center plane. The U-shaped slide head 113 arranged on the guide rail element 105 has two side edges, and four rollers 139 are arranged on the inner sides of the two side edges as a guide mechanism for the slide 103 on the guide rail element 105. Each roller 139 corresponds to an inner working surface 141 of the guide rail element 105 with a T-shaped cross section.

[0066] Magnetic plates 117 are respectively provided on the inner sides of the two side ends of the slide head 113, and these magnetic plates surround the drive coil winding 111 of the motor module 107. The magnetic plates 117 and the drive coil winding 111 located between the magnetic plates form a double air gap linear motor. The attractive force of the magnetic plates 117 is compensated on both sides of the drive coil winding 111 of the motor module 107, so the roller 139 of the slide 103 is very little worn when rolling on the working surface 141 of the guide rail element 105.

[0067] like Figure 3 As shown in the cross section in FIG. 1 , the position element 143 is connected to one of the sides of the slide head 113 and is in the form of a sheet-like transmitter with a metal surface, which extends parallel to the motor module 107 of the slide guide 102. The position element 143 on the slide 103 is located at the same Figure 1 and Figure 2 The side of the carriage opposite the side of the carriage shown is therefore not shown in these figures.

[0068] The same is true for the position sensor device 145 on the motor module 107 of the slide guide 102, which cooperates with the position element 143 on the slide 103 to determine the position of the slide 103. The position sensor device 145 arranged in the motor module 107 opposite to the position element 143 on the slide 103 is at least one energized coil extending along the motor module 107, and its current changes under the action of the position element 143, thereby detecting the position of the position element 143, and then detecting the position of the slide 103.

[0069] As an alternative to detecting the position of the slide 103 using an independent system consisting of a position element 143 on the slide 103 and a position sensor device 145 in the motor module 107 of the slide guide 102, the position data of the slide 103 can also be determined based on the energization of the drive coil winding 111 of the motor module 107. Another method of determining the position data is to detect the magnetic plate 117 on the slide 103 by means of a magnetic field sensor (e.g., a 3D Hall sensor) arranged on the motor module 107 of the slide guide 102.

[0070] like Figure 1 and Figure 2 As shown in the side view in FIG. 1 , in order to transmit data between the slide guide 102 and the slide 103, the motor module 107 has an antenna array 129 extending along the slide guide 102. The slide 103 is also provided with a slide antenna 131, which is located in an attachment 119 on the slide head 113. Figure 3 As shown, the attachment 119 is located on the other side of the slide head 113, opposite to the positioning element 143 designed as a sheet-like transmitter with a metal surface, and extends beyond the end of the side parallel to the motor module 107 of the slide guide 102. The slide antenna 131 is fixed to the area of ​​the slide head attachment 119 opposite to the antenna array 129.

[0071] Data can be exchanged between the carriage guide 102 and the carriage 103 by means of the antenna array 129 and the carriage antenna 131. Alternatively, data can also be transmitted directly between the carriage 103 and the carriage guide control unit 133 of the motor module 107 via wireless LAN, Bluetooth, infrared, 5G connection, DECT standard connection or optical link, without connecting components of the carriage guide 102 between the two.

[0072] The data transmission from the carriage guide 102 of the linear transport system 101 to the carriage 103 is carried out as follows: First, the carriage guide control unit 133 determines the position data of the carriage 103 by means of the position sensor device 145 on the carriage guide 102 and the position element 143 on the carriage 103. Then, the carriage guide control unit 133 selects an antenna from the antenna array 129 of the carriage guide 102 that is opposite to the carriage 103 and thus opposite to the carriage antenna 131. Then, the carriage guide control unit 133 outputs a data packet to the motor module 107 arranged with the selected antenna. The data packet includes a control signal for identifying the selected antenna and a data signal transmitted by the selected antenna. The data signal includes a start sequence and valid data, wherein the start sequence is used to trigger the carriage 103 to receive data. In order to receive data, the carriage 103 has a carriage control unit 121 connected to the carriage antenna 131 and arranged in the carriage head attachment 119.

[0073] The data exchange between the slide guide 102 and the slide 103 is mutual. The slide control unit 121 can also transmit data packets to the antenna array 129 of the slide guide 102 through the slide antenna 131, and then the antenna in the antenna array 129 opposite to the slide 103 and the slide antenna 131 receives the data packets and forwards them to the slide guide control unit 133.

[0074] A load 137 is also disposed on the slide 103. The load 137 is shown in the figure as a position marker, and can be designed as an electric tool, for example.

[0075] In order to provide electrical energy to the carriage control unit 121 and the load 137, an inductive energy transmission device is provided. The inductive energy transmission device has an array of energy transmission coils 125 adjacent to the antenna array 129 and extending along the carriage guide 102. Figure 1 and Figure 2 As shown in the figure, each motor module 107 corresponds to at least one energy transmission coil 125, so that continuous inductive energy transmission can be performed along the slide guide 102. In order to perform fixed-point inductive energy transmission, only individual motor modules can have energy transmission coils 125 instead of providing a closed energy transmission coil array.

[0076] like Figure 3 As shown in the cross-sectional view in FIG, each slide 103 of the inductive energy transmission device is provided with an energy receiving coil 127, which is located on the slide head attachment 119 and adjacent to the slide antenna 131. The energy receiving coil 127 is arranged on the slide head attachment 119 in a manner opposite to the array of energy transmitting coils 125 on the slide guide 102, wherein the energy receiving coil 127 on the slide 103 covers the energy transmitting coil 125 on the motor module 107. The area occupied by the energy transmitting coil 125 on the motor module 107 is rectangular, while the energy receiving coil 127 on the slide 103 may be square. However, the energy receiving coil 127 on the slide 103 may also be rectangular.

[0077] The amount of energy transmission can also be determined by the size of the air gap between the energy transmitting coil 125 and the energy receiving coil 127. In order to adjust the air gap as optimally as possible, while also taking into account manufacturing tolerances, it is advantageous to provide adjustment means, for example in the form of screws, on the slide 103, by means of which the distance between the slide head attachment 119 and the slide head 113 and thus the air gap can be set and readjusted.

[0078] The energy transmitting coil 125 on the motor module 107 has a primary winding 126 with a continuous winding wire. The secondary winding 128 of the energy receiving coil 127 on the carriage 103 is divided into two winding parts, namely a control voltage winding part 146 and a load voltage winding part 147, which have separate winding wires.

[0079] Figure 4 A first embodiment of an inductive energy transmission device is shown in a highly schematic diagram, wherein Figure 4 A shows a cross-sectional view of an inductive energy transfer device, Figure 4 B shows a side view of the inductive energy transfer device, Figure 4 C shows a top view of the energy transmitting coil 125 from the perspective of the energy receiving coil 127, Figure 4 D shows a top view of the energy receiving coil 127 as seen from the direction of the energy transmitting coil 125 .

[0080] The energy transmitting coil 125 and the energy receiving coil 127 each have a bobbin 135 with an E-shaped cross-section, wherein the bobbin can be an energy transmitting coil bobbin 148 and / or an energy receiving coil bobbin 153, having two outer arm ribs 202 and a central rib 204 located therebetween, wherein the outer arm ribs can be referred to as first energy transmitting coil outer arm ribs 150 and / or second energy transmitting coil outer arm ribs 151 and / or first energy receiving coil outer arm ribs 155 and / or second energy receiving coil outer arm ribs 156, and the central rib can be referred to as energy transmitting coil central rib 152 and / or energy receiving coil central rib 157, and is located on the bobbin surface 136, wherein the bobbin surface can be referred to as energy transmitting coil bobbin surface 149 and / or energy receiving coil bobbin surface 154. The E-shaped cross-section of the energy transmitting coil bobbin 148 of the energy transmitting coil 125 and the E-shaped cross-section of the energy receiving coil bobbin 153 of the energy receiving coil 127 face each other, wherein the outer arm ribs 202 and the center rib 204 on the bobbin surface 136 are opposite to each other, and an air gap is formed between the bobbins 135.

[0081] The bobbin 135 is preferably made of a ferromagnetic material, which may be a ferrite, a high frequency ferrite or a ferrite. The ferromagnetic material of the bobbin 135 can provide a high inductance. However, the bobbin 135 can also be made of a non-ferromagnetic material to provide an inductance that is independent of the coil current.

[0082] like Figure 4 As shown in the top view in C, the energy transmitting coil 125 is designed as a flat coil. Figure 4 The sectional view in A and Figure 4As shown in the side view in FIG. B, the winding wire of the primary winding 126 of the energy transmitting coil 125 is spirally wound on the energy transmitting coil center rib 152 of the energy transmitting coil bobbin 148, and extends between the energy transmitting coil center rib 152 and the first energy transmitting coil outer arm rib 150 and the second energy transmitting coil outer arm rib 151. Figure 4 As shown in the top view in C, the two free ends of the winding wire extend laterally outward and serve as terminals for applying voltage.

[0083] exist Figure 4 In the illustrated embodiment, the primary winding 126 has six mutually insulated turns of wire. However, more or fewer windings may be provided depending on the desired inductance value to be achieved in the primary winding 126. Depending on the size of the bobbin surface 136, the coil winding may also be multi-layered.

[0084] like Figure 4 The sectional view in A and Figure 4 As shown in the side view in FIG. B, the secondary winding 128 of the energy receiving coil 127 is wound in such a manner that the winding wire extends around the energy receiving coil bobbin surface 154 between the first energy receiving coil outer arm rib 155, the second energy receiving coil outer arm rib 156 and the energy receiving coil center rib 157. Therefore, the energy receiving coil bobbin surface 154 spanned by the secondary winding 128 is perpendicular to the energy transmitting coil bobbin surface 154 spanned by the primary winding 126.

[0085] The winding wire of the secondary winding 128 of the energy receiving coil 127 is divided into a control voltage winding part 146 and a load voltage winding part 147. Figure 4 In the illustrated embodiment, the control voltage winding portion 146 and the load voltage winding portion 147 are staggered with each other, wherein the control voltage winding portion 146 and the load voltage winding portion 147 are respectively formed symmetrically with respect to the energy receiving coil center rib 157 of the energy receiving coil bobbin 153 .

[0086] like Figure 4 The sectional view in A and Figure 4As shown in the side view in FIG. B, the control voltage winding part 146 and the load voltage winding part 147 respectively have a first control voltage winding part winding segment 180 and a first load voltage winding part winding segment 182 in the first energy receiving coil bobbin surface part 158 ​​of the energy receiving coil bobbin surface 154 (the first energy receiving coil bobbin surface part extends between the first energy receiving coil outer arm rib 155 and the energy receiving coil center rib 157), and respectively have a second control voltage winding part winding segment 181 and a second load voltage winding part winding segment 183 in the second energy receiving coil bobbin surface part 159 of the energy receiving coil bobbin surface 154 (the second energy receiving coil bobbin surface part extends between the energy receiving coil center rib 157 and the second energy receiving coil outer arm rib 156). Figure 4 As shown in the side view in FIG. B, the winding wires of the two winding sections of the control voltage winding part 146 and the load voltage winding part 147 are connected to each other through wires arranged on the rear side of the coil surface. Figure 4 As shown in the top view in FIG. 1 , the connecting wire is arranged laterally on the energy receiving coil bobbin 153. The two free ends of the winding wires of the control voltage winding part 146 and the load voltage winding part 147 are respectively used as terminals for tapping the voltage and are arranged laterally outwardly on the energy receiving coil bobbin 153 opposite to the connecting wire. The winding directions of the two windings are further rotated in their respective winding sections.

[0087] like Figure 4 The sectional view in A and Figure 4 As shown in the side view in FIG. 1B , the winding sections of the control voltage winding section 146 and the load voltage winding section 147 are arranged as follows: the first control voltage winding section 180 of the control voltage winding section is wound on the first energy receiving coil bobbin surface section 158 of the energy receiving coil bobbin surface 154 of the energy receiving coil 127 adjacent to the first energy receiving coil outer arm rib 155. Then, in the first energy receiving coil bobbin surface section 158 of the energy receiving coil bobbin surface 154 of the energy receiving coil 127, the first load voltage winding section 182 of the load voltage winding section 147 is connected thereto and extends to the energy receiving coil center rib 157. Then, the second winding sections of the control voltage winding section 146 and the power voltage winding section 147 are formed symmetrically thereto. The second load voltage winding section 183 of the load voltage winding section 147 is wound on the second energy receiving coil bobbin surface section 159 of the energy receiving coil bobbin surface 154 of the energy receiving coil 127 adjacent to the energy receiving coil center rib 157. The second control voltage winding section winding segment 181 of the control voltage winding section 146 then extends in the remaining region of the second energy receiving coil bobbin surface section 159 of the energy receiving coil bobbin surface 154 of the energy receiving coil 127 to the second energy receiving coil outer arm rib 156 .

[0088] The connecting wire between the first load voltage winding section 182 and the second load voltage winding section 183 of the load voltage winding section 147 is adjacent to the energy transmitting coil bobbin 148 and is guided along the energy receiving coil center rib 157. The connecting wire between the first control voltage winding section 180 and the second control voltage winding section 181 of the control voltage winding section 146 extends to the winding section of the load voltage winding section 147.

[0089] The staggered arrangement of the control voltage winding section 146 and the load voltage winding section 147 of the energy receiving coil 127 ensures that there is a symmetrical magnetic flux in the energy receiving coil bobbin 153. By arranging the control voltage winding section 146 and the load voltage winding section 147 perpendicular to the energy receiving coil bobbin 153 of the energy receiving coil 127, the winding space can be better utilized. Compared with the planar winding design of the energy transmitting coil center rib 153 around the energy transmitting coil bobbin 148, the vertical winding design of the energy receiving coil 127 will produce double the winding space. However, the magnetic flux (magnetischer Durchfluss) remains unchanged because the magnetic flux through the bobbin center rib is higher than the magnetic flux through the first and second outer ribs of the bobbin. Due to the increased winding space, the number of turns of the winding can be increased with the same cross section, resulting in an increase in inductance.

[0090] By dividing the secondary winding 128 of the energy receiving coil 127 into a control voltage winding section 146 and a load voltage winding section 147, the energy supply to the carriage control unit 121 and the energy supply to the load 137 can be optimized separately. The number of turns can be used to set the voltage required in each case. For example, the control voltage winding section 146 can provide a 24V control voltage in open circuit operation, while the load voltage winding section 147 can provide a 48V load voltage in open circuit operation. In this case, the number of turns of the control voltage winding section 146 is less than the number of turns of the load voltage winding section 147. In Figure 4 In the embodiment shown, the control voltage winding part 146 has 7 turns and the load voltage winding part 147 has 16 turns, wherein two layers of turns are always implemented. However, depending on the bobbin size, more or fewer layers of turns can also be provided.

[0091] By dividing the secondary winding 128 of the energy receiving coil 127 into a control voltage winding part 146 and a load voltage winding part 147, the cross section of the winding wire can also be adapted to the power requirements of the connected electrical devices (i.e., the carriage control unit 121 and the load 137 on the carriage). Since the power requirement of the carriage control unit 121 is usually lower than the power requirement of the sensor or actuator on the carriage 103, the cross section of the winding wire of the control voltage winding part 146 is designed to be smaller than the cross section of the winding wire of the load voltage winding part 147, such as Figure 4 As shown in the implementation method in .

[0092] Figure 5 A second embodiment of an inductive energy transmission device is shown in highly schematic form, wherein Figure 5 A is a cross-sectional view of an inductive energy transmission device, Figure 5 B is a side view of the inductive energy transmission device, Figure 5 C is a top view of the energy transmitting coil 125 from the perspective of the energy receiving coil 127. Figure 5 D is a top view of the energy receiving coil 127 viewed from the direction of the energy transmitting coil 125 .

[0093] Figure 5 The structure and the second embodiment of the inductive energy transmission device Figure 4 The structures of the first embodiment of the inductive energy transmission device are basically the same. The structures of the energy receiving coil 127 of the first and second embodiments of the inductive energy transmission device are exactly the same. The difference between the first and second embodiments lies in the design of the secondary winding 128 of the energy receiving coil 127.

[0094] In a first embodiment, if Figure 4 As shown, the control voltage winding portion 146 and the load voltage winding portion 147 of the energy receiving coil 127 are arranged alternately. Figure 5 In the second embodiment shown, the control voltage winding section 146 and the load voltage winding section 147 are spatially separated from each other.

[0095] like Figure 5As shown, the load voltage winding part 147 is wound on the first energy receiving coil part 158 ​​of the energy receiving coil bobbin surface 154 between the first energy receiving coil outer arm rib 155 and the energy receiving coil center rib 157, while the control voltage winding part 146 is wound on the second energy receiving coil bobbin surface part 159 of the energy receiving coil bobbin surface 154 between the energy receiving coil center rib 157 and the second energy receiving coil outer arm rib 156. In this case, the load voltage winding part 147 designed with a larger winding wire cross section covers the entire surface of the part. The control voltage winding part 146 has a smaller winding wire cross section and a smaller number of turns, and only extends on a partial area of ​​the second energy receiving coil bobbin surface part 159 of the energy receiving coil bobbin surface 154 adjacent to the second energy receiving coil outer arm rib 156.

[0096] Since the control voltage winding portion 146 and the load voltage winding portion 147 of the energy receiving coil 127 are arranged separately, there is no need to Figure 4 As in the embodiment of the present invention, connecting wires are provided for the winding segments on the energy receiving coil center rib 157 of the energy receiving coil bobbin 153, thereby simplifying the structure.

[0097] Figure 6 Shown in a highly schematic manner Figure 4 A variation of the first embodiment of the inductive energy transmission device is provided, in which both the energy transmitting coil 125 and the energy receiving coil 127 are implemented as circuit board coils. In addition, in this variation, a cooling device 164 is further provided on the energy receiving coil 127. Figure 6 A is a cross-sectional view of an inductive energy transfer device. Figure 6 B is a top view of the inductive energy transmission device. Figure 6 C is a bottom view of the inductive energy transfer device.

[0098] In the circuit board coil design, printed wires are provided on a printed circuit board made of an electrically insulating material instead of winding wires. The energy transmitting coil 125 is designed as a flat coil, which is formed by printing wires in a spiral shape on the energy transmitting coil printed circuit board 160. In addition, a groove is provided on the energy transmitting coil printed circuit board 160, and the energy transmitting coil bobbin 148 having an E-shaped cross section is engaged with the groove, wherein the printed wire is located between the central rib and the first and second outer arm ribs of the bobbin.

[0099] The energy receiving coil 127 has a first energy receiving coil printed circuit board 161 and a second energy receiving coil printed circuit board 162. The first energy receiving coil printed circuit board 161 has a first wire portion of the control voltage winding portion 146 and a first wire portion of the load voltage winding portion 147 printed thereon, and the second energy receiving coil printed circuit board 162 has a second wire portion of the control voltage winding portion 146 and a second wire portion of the load voltage winding portion 147 printed thereon. Figure 6 The view in C further shows that the first wire portion of the control voltage winding portion 146 on the first energy receiving coil printed circuit board 161 and the second wire portion of the control voltage winding portion 146 on the second energy receiving coil printed circuit board 162, as well as the first wire portion of the load voltage winding portion 147 on the first energy receiving coil printed circuit board 161 and the second wire portion of the load voltage winding portion 147 on the second energy receiving coil printed circuit board 162 are respectively connected to each other through the electrical connector 184 to respectively form the closed control voltage winding portion 146 and the closed load voltage winding portion 147 of the secondary winding 128 of the energy receiving coil 127.

[0100] like Figure 6 As shown in the cross-sectional view in A, a groove is provided on the first energy receiving coil printed circuit board 161 of the energy receiving coil 127 for accommodating the energy receiving coil bobbin 153 with an E-shaped cross section. The energy receiving coil bobbin is arranged between the first energy receiving coil printed circuit board 161 and the second energy receiving coil printed circuit board 162, and is engaged with the groove of the first energy receiving coil printed circuit board 161.

[0101] On the side of the energy receiving coil 127 away from the energy transmitting coil 125, a cooling device 164 for the secondary winding 128 of the energy receiving coil 127 is provided. It is possible to install the cooling device 164 on the secondary winding 128 because the secondary winding 128 is designed vertically, which makes one winding side outside the voltage transformer formed by the energy transmitting coil 125 and the energy receiving coil 127 and is therefore accessible. The design of the cooling device 164 allows the cooling device 164 to extend outward from the slide head attachment 119 and can be cooled by the running wind of the slide 103. Cooling fins as a heat sink are particularly suitable for this purpose.

[0102] exist Figure 4 A first embodiment of the inductive energy transmission device is as follows Figure 6 In the variant shown, the energy transmitting coil 125 and the energy receiving coil 127 are respectively designed as circuit board coils. This variant can also be used for Figure 5 The second embodiment of the inductive energy transmission device shown. Figure 4 and Figure 5In the embodiment shown in which winding wires are used instead of printed wires, a cooling device 164 may also be provided. In this case, Figure 6 The variant shown may also not provide the cooling device 164 on the energy receiving coil 127. In addition, when designing the inductive energy transmission device, the circuit board coil and the wound coil may be used as the energy transmitting coil and the energy receiving coil respectively.

[0103] The energy transmission from the carriage guide 102 with the motor module device to the carriage 103 is performed in the following manner: during the movement of the carriage 103, the position data of the carriage 103 is continuously determined. Then, the carriage guide control unit 133 selects the motor module 107 that meets the following conditions: the energy receiving coil 127 of the carriage 103 is opposite to the energy transmitting coil 125 of the motor module 107. However, multiple motor modules 107 can also be selected at the same time, especially when the energy receiving coil 127 of the carriage 103 overlaps with the energy transmitting coil 125 of the adjacent motor module 107. The carriage guide control unit 133 further determines the energy to be transmitted by the energy transmitting coil 125 of the selected motor module 107. Then, an AC voltage or an AC current is applied to the energy transmitting coil 125 of the inductive energy transmission device accordingly to provide the energy to be transmitted.

[0104] Figure 7 The circuit diagram of the carriage guide 102 for controlling the energy transmitting coils 125 is shown. Each energy transmitting coil 125 is connected to an energy transmitting coil switch 174. Figure 7 In the embodiment shown, the energy transmission coil switch is designed as an H bridge. The energy transmission coil switch 174 is operated by the upstream energy transmission coil driver 163, which is in turn controlled by the energy transmission coil microcontroller 165. The energy transmission coil microcontroller 165 can control the energy transmission coil drivers 163 of all motor modules 107, such as Figure 7 As shown. A separate microcontroller can also be provided for each energy transmission coil driver 163 or driver group, in particular a motor module. The energy transmission coil microcontroller 165 is connected to the slide guide control unit 133 via an energy transmission coil communication interface 167. For power control, the energy transmission coil switch 174 is also equipped with an energy transmission coil ammeter 173, which is connected to the energy transmission coil microcontroller 165 and is used to feed back the energy emitted by the relevant energy transmission coil 125 to the energy transmission coil microcontroller 165.

[0105] The voltage applied to the primary winding 126 of the energy transmitting coil 125 changes the magnetic flux in the energy receiving coil 127, thereby generating AC voltages in the control voltage winding portion 146 and the load voltage winding portion 147 of the secondary winding 128 of the energy receiving coil 127. For example, by appropriately designing the control voltage winding portion 146 and the load voltage winding portion 147, an open circuit voltage of 24 V can be obtained in the control voltage winding portion 146 and an open circuit voltage of 48 V can be obtained in the load voltage winding portion 147. The required voltage value can be set by the number of turns of the winding or the relevant wire cross section.

[0106] The control voltage winding part 146 and the load voltage winding part 147 are connected to a rectifier, respectively. In addition, capacitors for smoothing can be added to the control voltage circuit and the load voltage circuit, respectively. The slide control unit 121 can also be used to monitor and influence the load voltage. A switch is then provided in the load voltage circuit so that the load 137 can be disconnected from the load voltage winding part 147 when necessary. The switch can be operated by the slide control unit 121. Therefore, when the load in the load voltage circuit fluctuates, the slide control unit 121 can interrupt the connection between the load voltage winding part 147 and the load 137 by means of the switch to prevent, for example, an overvoltage in the load voltage circuit when the load suddenly drops, which can damage the electronic components in the load voltage circuit. If necessary, disconnecting the load voltage circuit can also be used to save energy.

[0107] Compared with the design in which the voltage value is set by the slide guide control unit 133, the slide control unit 121 directly controls the load voltage circuit on the slide 103, which is much faster because the former needs to transmit the voltage value from the slide 103 to the slide guide control unit 133 first.

[0108] Energy storage devices may be provided in the control voltage circuit and the load voltage circuit, respectively, to store energy in the middle and then provide the energy to the carriage control unit 121 and / or the load 137 when necessary. Better energy storage can be achieved by providing two independent voltages on the carriage 103 through the control voltage winding part 146 and the load voltage winding part 147. This makes it possible to decide whether to buffer the control voltage or the load voltage, depending on the selection of the respective energy storage devices in the control voltage circuit or the load voltage circuit.

[0109] Figure 8 and Fig. 9 A circuit diagram showing a control voltage circuit and a load voltage circuit on the slide 103, wherein Fig. 9 In the illustrated embodiment, an energy storage device is further provided.

[0110] like Figure 8As shown, the control voltage winding section 146 is connected to a first rectifier 191, which in turn is connected to the carriage guide control unit 133 via a first smoothing capacitor 192 in between. The load voltage winding section 147 is connected to a second rectifier 193. The second rectifier 193 is connected to the load 137 via a load voltage circuit switch 195 and a second smoothing capacitor 194 in between. The load voltage circuit switch 195 is in turn connected to the carriage guide control unit 133 and can be opened or closed by the carriage guide control unit 133.

[0111] A load voltage circuit ammeter 196 is also provided in the load voltage circuit between the second rectifier 193 and the load 137 . The load voltage circuit ammeter 196 is connected to the slide guide control unit 133 and feeds back the current value in the load voltage circuit to the slide guide control unit 133 .

[0112] Fig. 9 show Figure 8 The control voltage winding portion 146 is connected in parallel with the control voltage circuit and is connected to the first energy storage 199 through the third smoothing capacitor 197. The first energy storage 199 is further connected to the control voltage circuit.

[0113] Furthermore, a second energy store 200 is provided, which is connected in parallel with the load voltage circuit and is connected to the load voltage winding part 147 via a fourth smoothing capacitor 198. The second energy store 200 is further connected to the load voltage circuit.

[0114] The first energy storage device 199 and the second energy storage device 200 are controlled by the carriage guide control unit 133. Therefore, the carriage guide control unit 133 can buffer the control voltage in the first energy storage device 199 according to the requirements of the control voltage circuit, and can buffer the load voltage in the second energy storage device 200 according to the requirements of the load voltage circuit. If necessary, the carriage guide control unit 133 can feed back the buffered energy to the control voltage circuit or the load voltage circuit.

[0115] like Fig. 9 As shown in the embodiment in FIG. 1 , the first energy store 199 and the second energy store 200 can form a common energy store in order to provide buffered energy to the carriage controller and / or sensors or actuators connected in the load voltage circuit, depending on the requirements and the carriage application.
