Description

Technical Field

[0001] The present invention relates to an electromechanical joining module as recited in the preamble of the independent claim.

Background Art

[0002] Electromechanical joining modules are used in industrial production in various assembly and joining processes such as stamping, punching, riveting, clinching, etc. The electromechanical joining module includes an electric motor, a screw drive unit, a tappet, and a force transducer. The electric motor is operably connected to the screw drive unit, and the rotational movement of the electric drive unit is converted into linear movement by the screw drive unit. The tappet and the force transducer are attached to the screw drive unit and move in a linear motion. The tappet and the force transducer move linearly over a stroke length of several hundred millimeters. The electromechanical joining module exhibits a high-speed movement of about 400 mm / second, a high stroke speed exceeding 10 strokes / minute, and a high repeatability accuracy of 0.01 mm for efficient production. The force transducer measures the digitized force applied by the tappet. The force transducer generates measurement data of the measured force. The measurement data exhibits a measurement accuracy of 0.5%.

[0003] Such an electromechanical joining module is known from International Publication No. WO 2011 / 009223 A1. The electric motor and the screw drive unit form a drive unit. The drive unit includes a stator. The stator is fixed. The tappet can move linearly with respect to the stator. The tappet includes a tappet end facing away from the drive unit. The force transducer is attached to the tappet end.

[0004] According to the teachings in the literature, International Publication No. 2011009223A1, the tappet comprises tappet electronic components and a tappet coil for this purpose. The tappet coil extends over the entire stroke length. The tappet coil has a single winding and is positioned in the groove of the tappet. The stator comprises stator electronic components and a stator coil. The stator coil is U-shaped and maintains a close position to the tappet coil during the course of linear motion. The tappet electronic components and stator electronic components are suitable for transmitting measurement data from the tappet coil to the stator coil by near-field telemetry. This requires inductive coupling between the tappet coil and the stator coil. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] International Patent Application Publication No. 2011009223A1 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] The objective of this invention is to improve the availability of the transmission of measurement data, as described in the literature, International Publication No. 2011009223A1, and to simplify its design and implement it cost-effectively. [Means for solving the problem]

[0007] This objective is resolved by the features of the independent claim.

[0008] The present invention relates to an electromechanical junction module for applying force, the electromechanical junction module comprising a drive unit and a tappet, the tappet being mounted on the drive unit and capable of being moved linearly by the drive unit, the electromechanical junction module comprising a force transducer, the force transducer being mounted on the tappet and capable of measuring the applied force and generating a measurement of the measured force, the electromechanical junction module comprising a fixed stator, the tappet and force transducer being capable of being moved linearly relative to the stator over a stroke length, the tappet comprising tappet electronic components and a tappet coil, the stator comprising stator electronic components and a stator coil, the tappet coil maintaining a close position relative to the stator coil during the course of linear motion, the tappet electronic components and stator electronic components being suitable for transmitting the measurement as measurement data from the tappet coil to the stator coil by near-field telemetry, the stator coil extending over the entire stroke length.

[0009] In contrast to the electromechanical coupling module of the present invention, the stator coil extends over the entire stroke length.

[0010] The electromechanical junction module according to the present invention has several advantages. a. In tappets, the fact that space is no longer required to accommodate the tappet coil extending over the entire stroke length means that the tappet gains mechanical stability. The groove is eliminated. Gaining mechanical stability reduces the bending of the tappet when force is applied. This further reduces the possibility that the stator coil and tappet coil, which are located in close proximity to each other, may come into contact as a result of tappet bending, which would interrupt the transmission of measurement data and impair the availability of the electromagnetic coupling module. b. By eliminating the tappet groove, the interruption of inductive coupling during the near-field telemetry process is prevented, which further improves the transmission of measurement data and, consequently, enhances the availability of the electromagnetic coupling module. c. This tappet is further guided by a sliding bearing within the stator, and according to the teachings in the literature, International Publication No. 2011009223A1, the guide surface must be manufactured with high precision even in the complex and costly area of ​​the tappet coil. d. Finally, a relatively large amount of space is available on the stator, which radially surrounds the stator, for arranging the stator coils that extend over the entire stroke length. This allows for a structurally simple and cost-effective arrangement of the stator coils on the stator.

[0011] Advantageous embodiments of the electromechanical junction module according to the present invention are listed in the dependent claims.

[0012] The present invention will be described in more detail below with reference to preferred exemplary embodiments, using the figures. [Brief explanation of the drawing]

[0013] [Figure 1] This is a diagram showing a part of the electromechanical junction module 1. [Figure 2] Figure 1 is a schematic diagram of a portion of the electromechanical junction module 1, specifically the tappet 30 equipped with a tappet coil 32, and the stator 20 equipped with a stator coil 22 and a transformer coil 25. [Modes for carrying out the invention]

[0014] The same reference number in the diagram indicates the same object.

[0015] Figure 1 shows a partial view of the electromechanical junction module 1. The electromechanical junction module 1 comprises a drive unit 10, a stator 20, a tappet 30, and a power transducer 40. Further details can be seen in the enlarged sections on the left, center, and right of Figure 1. The electromechanical junction module 1 also includes an evaluation unit 50, which can be seen in the schematic diagram of Figure 2.

[0016] The drive unit 10 exhibits the function of applying a force K via the tappet 30. The force K may be applied to joints not shown in the figure. The drive unit 10 may comprise an electric motor, a screw drive unit, a brake, and a control unit. The electric motor and the screw drive unit are operably connected, and the rotational motion of the electric drive unit is converted into linear motion by the screw drive unit. The linear motion occurs along the longitudinal axis A of the electromechanical joint module 1. The force K is applied by the linear motion. The linear motion can apply a very small force K of a few mN, or a very large force of several hundred kN. The linear motion is controlled by the control unit. The brake can decelerate the linear motion. A travel speed of approximately 400 mm / second is achieved with a repeatability of 0.01 mm. The drive unit 10 has a drive unit end 14 on the longitudinal axis A.

[0017] The stator 20 provides a housing function, enclosing the tappet 30 at least partially radially, thereby protecting the tappet 30 from harmful environmental influences such as contaminants (dust, moisture, etc.). The stator 20 is fixed. The term "fixed" means that the stator 20 maintains its position while the tappet 30 is moving. The tappet 30, therefore, moves linearly relative to the stator 20. The stator 20 includes a stator end 24 facing away from the drive unit 10.

[0018] The tappet 30 is attached to the drive unit end 14 and moves in linear motion. The tappet 30 can move linearly over a stroke length L of several hundred mm. The stroke length L extends along the longitudinal axis A of the electromechanical joint module 1. In the exemplary embodiment shown in Figure 1, the stroke length L extends from the drive unit end 14 to the stator end 24.

[0019] The tappet 30 has a tappet end 34 facing away from the drive unit 10. Details of the tappet end 34 can be checked in the enlarged part on the left side of FIG. 1. The tappet 30 applies a force K via the tappet end 34. The force transducer 40 is attached to the tappet end 34.

[0020] The force transducer 40 exhibits the function of measuring the force K applied by the tappet 30. The force transducer 40 can be a strain gauge or a piezoelectric sensor. The force transducer 40 is not limited to measuring the force K. The force transducer 40 can also measure momentum such as bending moment, torque, etc. applied by the tappet 30. The force transducer 40 can measure the force K over several digits. The force transducer 40 has a tool holder for attaching tools not shown in the figure. The force transducer 40 moves together with the tappet 30.

[0021] The tappet 30 has tappet electronics 31. The tappet electronics 31 can be arranged at the tappet end 34. The force transducer 40 is electrically connected to the tappet electronics 31 via at least one force transducer wire 43. The force transducer wire 43 is made of a conductive material such as copper. The exemplary embodiment of FIG. 1 has a plurality of wire-shaped force transducer wires 43. The force transducer 40 generates a measured value MW of the measured force K. The measured value MW is an analog signal such as the voltage of a strain gauge or the charge of a piezoelectric sensor. The force transducer 40 transmits the measured value MW to the tappet electronics 31 via the force transducer wire 43. The tappet electronics 31 is suitable for converting the measured value MW into measurement data MD. When converting the measured value MW into measurement data MD, the tappet electronics 31 electrically amplifies and digitizes the measured value MW. For this purpose, the tappet electronics 31 amplifies the measured value MW within the measurement range. The tappet electronics 31 sets or changes one of a plurality of possible measurement ranges for electrical amplification. The measurement data MD is digital data. The measurement data MD exhibits a measurement accuracy of 0.5% or less.

[0022] The measurement data MD is evaluated by the evaluation unit 50. The evaluation unit 50 can be arranged away from the electromechanical bonding module 1. In the schematic illustration of FIG. 2, the evaluation unit 50 is electrically connected to the stator electronic component 21 via the evaluation unit line 53. The measurement data MD is transmitted for evaluation first from the tappet electronic component 31 to the stator electronic component 21, and then from the stator electronic component 21 to the evaluation unit 50. The measurement data MD is transmitted from the tappet 30 to the stator 20 using the near-field remote measurement method. The near-field remote measurement method is a method known in the ISO / IEC 14443 or ISO / IEC 15693 series of standards for non-contact transmission of digital data by electromagnetic induction using a coil.

[0023] Hereinafter, the inductive coupling between the coil of the tappet 30 and the coil of the stator 20 will be described in detail.

[0024] The stator 20 includes a stator electronic component 21, a stator coil 22, and at least one stator line 23, 26. The stator lines 23, 26 are made of a conductive material such as copper. The stator lines 23, 26 are preferably the first stator line 23 and the second stator line 26. The exemplary embodiments of FIGS. 1 and 2 include a plurality of wire-shaped first stator lines 23 and a plurality of wire-shaped second stator lines 26.

[0025] The near-field remote measurement method is performed using at least one carrier frequency F1, F2. The carrier frequencies F1, F2 are preferably the first carrier frequency F1 of 13.56 MHz and the second carrier frequency F2 in the range of 119 to 135 kHz. The tappet electronic component 31 is suitable for generating the first carrier frequency F1. The stator electronic component 21 is suitable for generating the second carrier frequency F2.

[0026] The stator 20 preferably includes a transformer coil 25. Details of the transformer coil 25 can be seen in the enlarged right portion of Figure 1. The stator electronic components 21 are preferably electrically connected to the transformer coil 25 via a first stator wire 23.

[0027] The stator electronic component 21 is suitable for generating an AC voltage having a second carrier frequency F2. The AC voltage is applied to the transformer coil 25 via the first stator wire 23. Hereafter, the AC voltage will also be referred to as the primary voltage U1 of the stator electronic component 21. The primary voltage U1 may be in the range of 10 to 20 V.

[0028] The transformer coil is preferably a toroidal core coil having a toroidal core made of a magnetic material such as iron or ferrite. The toroidal core of the transformer coil 25 has a central through hole 250. The central through hole 250 of the transformer coil 25 extends perpendicular to the longitudinal axis A of the electromechanical joint module 1. The transformer coil 25 comprises transformer coil windings 251 and 252. The transformer coil windings 251 and 252 are made of a conductive material such as copper. The transformer coil windings 251 and 252 are preferably a first transformer coil winding 251 and a second transformer coil winding 252. The number of first transformer coil windings 251 may range from 5 to 10. The number of second transformer coil windings 252 may range from 1 to 5. The number of second transformer coil windings 252 is preferably 1. The first transformer coil winding 251 is electrically connected to the first stator wire 23. The second transformer coil winding 252 is electrically connected to the second stator wire 26.

[0029] The transformer coil 25 exhibits the function of the transformer. The ratio of the number of first transformer coil windings 251 to the number of second transformer coil windings 252 is suitable for converting the primary voltage U1 to the secondary voltage U2. The secondary voltage U2 may be in the range of 1 to 2V. The secondary voltage U2 exhibits the second carrier frequency F2 of the primary voltage U1.

[0030] The stator coil 22 and the transformer coil 25 are positioned close to each other. The stator coil 22 and the transformer coil 25 are positioned within a few millimeters to a few centimeters of each other.

[0031] The stator coil 22 is made of a conductive material such as aluminum, brass, or steel. The stator coil 22 is mounted to the stator 20 in an electrically insulated manner. The stator coil 22 preferably comprises a single stator coil winding 221. The stator coil 22 preferably has a horseshoe shape with two long sides and one short side. The two long sides extend parallel to the longitudinal axis A of the electromechanical junction module 1.

[0032] The transformer coil 25 and the stator coil 22 are electrically connected via a second stator wire 26. This allows the secondary voltage U2 to be applied to the stator coil 22.

[0033] The secondary voltage U2 generates an alternating current in the stator coil 22. This alternating current forms a magnetic field. The magnetic field lines travel in a circular pattern around the stator coil winding 221.

[0034] The tappet 30 is equipped with a tappet coil 32. The tappet coil 32 maintains a close position to the stator coil 22 during linear motion. The distance between the tappet coil 32 and the stator coil 22 is several millimeters to several centimeters.

[0035] Details of the tappet coil 32 can be seen in the enlarged central section of Figure 1. The tappet coil 32 is also preferably a toroidal core coil, having a toroidal core made of a magnetic material such as iron or ferrite. The toroidal core of the tappet coil 32 has a central through-hole 320. The central through-hole 320 of the tappet coil 32 extends parallel to the longitudinal axis A of the electromechanical junction module 1. The tappet coil 32 comprises a plurality of tappet coil windings 321. The tappet coil windings 321 are made of a conductive material such as copper. The number of tappet coil windings 321 can range from 5 to 10. It is preferable that the number of first transformer coil windings 251 is equal to the number of tappet coil windings 321.

[0036] The stator coil 22 and the tappet coil 32 exhibit a function of establishing inductive coupling with each other. For this purpose, the stator coil 22 and the tappet coil 32 are positioned relative to each other such that the tappet coil 32 completely surrounds the winding 221 of the stator coil 22 in a specific region in a plane perpendicular to the longitudinal axis A. In the exemplary embodiments shown in Figures 1 and 2, the stator coil winding 221 protrudes through the central through-hole 320 of the tappet coil 32.

[0037] In a toroidal core coil, the magnetic field lines travel in a circular pattern within the toroidal core coil. This allows the magnetic field lines of the stator coil 22 to precisely follow the magnetic field lines of the tappet coil 32, resulting in optimal inductive coupling.

[0038] Therefore, the stator coil 22 and the tappet coil 32 are suitable for inducing an AC voltage U3 having a second carrier frequency F2 of the secondary voltage U2 in the tappet coil 32 by the secondary voltage U2 of the stator coil 22.

[0039] The stator coil 22 and tappet coil 32 also exhibit transformer function. The stator coil 22 and tappet coil 32 are suitable for converting the secondary voltage U2 of the stator coil 22 to the AC voltage U3 of the tappet coil 32. The ratio of the number of stator coil windings 221 to the number of tappet coil windings 321 converts the secondary voltage U2 of the stator coil 22 to the AC voltage U3 of the tappet coil 32. When the number of first transformer coil windings 251 and tappet coil windings 321 are the same, the AC voltage U3 of the tappet coil 32 is approximately equal to the primary voltage U1 of the transformer coil 25.

[0040] The tappet coil 32 is electrically connected to the tappet electronic component 31 via at least one tappet wire 33. The tappet wire 33 is made of a conductive material such as copper. The tappet wire 33 is electrically connected to the tappet winding 321 of the tappet coil 32. The tappet electronic component 31 is suitable for generating a first carrier frequency F1. The measurement data MD is introduced into the AC voltage U3 of the tappet coil 32 by modulating the first carrier frequency F1. Various modulation methods are possible, such as phase modulation and frequency modulation. Phase modulation is preferred. The tappet electronic component 31 is suitable for introducing the measurement data MD into the primary voltage U1 by phase modulation of the first carrier frequency F1 of the AC voltage U3 of the tappet coil 32. In this case, the first carrier frequency F1 is introduced into the secondary voltage U2 by conversion of the AC voltage U3, and the first carrier frequency F1 is introduced into the primary voltage U1 by conversion of the secondary voltage U2. The stator electronic component 21 demodulates the phase-modulated first carrier frequency F1 of the primary voltage U1, which is suitable for extracting measurement data MD from the primary voltage U1. The measurement data MD is transmitted from the stator electronic component 21 to the evaluation unit 50 for evaluation.

[0041] The inductive coupling between the stator coil 22 and the tappet coil 32 is also used to transmit additional data ZD from the tappet electronic component 31 to the stator electronic component 21. The additional data ZD is information relating to the tappet electronic component 31 and the force transducer 40, specifically either the sensitivity specification of the force transducer 40 or the measurement range specification of the tappet electronic component 31, which, in the conversion process, amplifies the measured value MW within this measurement range. The tappet electronic component 31 is suitable for introducing the additional data ZD into the primary voltage U1 by phase modulation of the first carrier frequency F1 of the AC voltage U3 of the tappet coil 32. The stator electronic component 21 is suitable for demodulating the phase-modulated first carrier frequency F1 of the primary voltage U1, thereby extracting the additional data ZD from the primary voltage U1. The additional data ZD is transmitted from the stator electronic component 21 to the evaluation unit 50 for evaluation.

[0042] The inductive coupling between the stator coil 22 and the tappet coil 32 is also used to transmit electrical energy from the stator electronic component 21 to the tappet electronic component 31. For this purpose, the tappet electronic component 31 is suitable for taking an AC voltage U3 from the tappet coil 32 and using the AC voltage U3 to supply power to the tappet electronic component 31 or the power transducer 40.

[0043] The inductive coupling between the stator coil 22 and the tappet coil 32 is also used to transmit control data SD from the stator electronic component 21 to the tappet electronic component 31. The control data SD is digital data. The control data SD can be used to control the operation of the tappet electronic component 31. The tappet electronic component 31 can thus be switched on and off using the control data SD. The tappet electronic component 31 can further set or change the measurement range using the control data SD, and in the process of switching, the tappet electronic component 31 amplifies the measured value MW within this measurement range. For this purpose, the stator electronic component 21 is suitable for introducing the control data SD into the AC voltage U3 of the tappet coil 32 by phase modulation of the second carrier frequency F2 of the primary voltage U1. The tappet electronic component 31 is suitable for demodulating the phase-modulated second carrier frequency F2 of the AC voltage U3 of the tappet coil 32, thereby extracting control data SD from the AC voltage U3 of the tappet coil 32, and for operating the tappet electronic component 31 using the control data SD.
