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, and clinching. The electromechanical joining module includes an electric motor, a screw drive, a tappet, and a force transducer. The electric motor is operably connected to the screw drive, and the rotational movement of the electric drive is converted into linear movement by the screw drive. The tappet and the force transducer are attached to the screw drive 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 force exerted by the tappet over several digits. 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 WO 2011 / 009223 A1. The electric motor and the screw drive form a drive unit. The drive unit includes a stator. The stator is fixed. The tappet can move linearly relative to the stator. The tappet includes a tappet end facing away from the drive unit. The force transducer is attached to the tappet end.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The object of the present invention is to improve the transmission of measurement data known from Document WO 2011 / 009223 A1 in terms of availability, simplify its design, and achieve it cost-effectively.

Means for Solving the Problems

[0007] This object is solved by the features of the independent claims.

[0008] The present invention relates to an electromechanical coupling module for applying a force, the electromechanical coupling module comprising a drive unit and a tappet, the tappet being attached to the drive unit and being linearly movable by the drive unit, the electromechanical coupling module comprising a force transducer, the force transducer being attached to the tappet, measuring the applied force and generating a measured value of the measured force, the electromechanical coupling module comprising a fixed stator, the tappet and the force transducer being linearly movable relative to the stator over a stroke length, the tappet comprising tappet electronics and a tappet coil, the stator comprising stator electronics and a stator coil, the tappet coil maintaining a proximity arrangement relative to the stator coil during the linear movement, and the tappet electronics and the stator electronics being suitable for transmitting the measured value as measurement data from the tappet coil to the stator coil by means of near-field telemetry, the stator coil extending over the entire stroke length.

[0009] The stator coil of the electromechanical coupling module according to the invention extends over the entire stroke length, in contrast to the electromechanical coupling module of document WO 2011 / 009223 A1.

[0010] The electromechanical coupling module according to the invention has several advantages. a. The fact that in the tappet there is no longer a need for space to accommodate a tappet coil extending over the entire stroke length means that the tappet obtains mechanical stability. The grooves are omitted. Obtaining mechanical stability reduces the buckling of the tappet when a force is applied. This further reduces the possibility that the stator coil and the tappet coil, which are arranged in proximity to each other, may come into contact as a result of the buckling of the tappet, which would interrupt the transmission of the measurement data and impair the usability of the electromagnetic coupling module. b. Omission of the grooves in the tappet also prevents interruption of the inductive coupling during the process of near-field telemetry, which further improves the transmission of the measurement data and thus the usability of the electromagnetic coupling module. c. This tappet is further guided in the stator by a sliding bearing, and according to the teachings of document WO 2011 / 009223 A1, the guiding surface must be manufactured with high precision even in the area of the tappet coil, which is complex and costly. d. And finally, relatively more space is available for the arrangement of the stator coil extending over the entire stroke length on the stator surrounding the stator radially. This enables a structurally simple and cost-effective arrangement of the stator coil on the stator.

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

[0012] In the following, the invention will be explained in more detail with reference to the preferred exemplary embodiments, using the figures.

Brief Description of the Drawings

Embodiments for Carrying Out the Invention

[0014] The same reference numerals in the figures denote the same objects.

[0015] FIG. 1 shows a view of a part of the electromechanical coupling module 1. The electromechanical coupling module 1 includes a drive unit 10, a stator 20, a tappet 30, and a force converter 40. Details can be confirmed in the enlarged parts on the left, center, and right of FIG. 1. The electromechanical coupling module 1 also includes an evaluation unit 50 that can be confirmed in the schematic view of FIG. 2.

[0016] The drive unit 10 exhibits the function of applying a force K via the tappet 30. The force K can be applied to a joining body not shown in the figure. The drive unit 10 can include 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 movement of the electric drive unit is converted into a linear movement by the screw drive unit. The linear movement occurs along the longitudinal axis A of the electromechanical joining module 1. The force K is applied by the linear movement. The linear movement can apply a very small force K of several mN, but can also apply a very large force of several hundred kN. The linear movement is controlled by the control unit. The brake can decelerate the linear movement. A moving speed of about 400 mm / second is achieved with a repeatability accuracy of 0.01 mm. The drive unit 10 includes a drive unit end 14 on the longitudinal axis A.

[0017] The stator 20 exhibits the function of a housing, at least partially surrounds the tappet 30 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 when the tappet 30 is moving. The tappet 30 thus 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 a 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 joining module 1. In the exemplary embodiment of FIG. 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 seen in the enlarged portion 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 the momentum such as the bending moment and torque 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 from 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 a first carrier frequency F1 of 13.56 MHz and a 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 confirmed in the enlarged portion on the right side of FIG. 1. The stator electronic component 21 is preferably electrically connected to the transformer coil 25 via the first stator line 23.

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

[0028] The transformer coil is preferably a toroidal core coil provided with 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 bonding module 1. The transformer coil 25 includes 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 the first transformer coil winding 251 and the second transformer coil winding 252. The number of turns of the first transformer coil winding 251 can be in the range of 5 to 10. The number of turns of the second transformer coil winding 252 can be in the range of 1 to 5. The number of turns of the second transformer coil winding 252 is preferably 1. The first transformer coil winding 251 is electrically connected to the first stator line 23. The second transformer coil winding 252 is electrically connected to the second stator line 26.

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

[0030] The stator coil 22 and the transformer coil 25 are arranged close to each other. The stator coil 22 and the transformer coil 25 are in a close arrangement within several millimeters to several centimeters.

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

[0032] The transformer coil 25 and the stator coil 22 are electrically connected via the second stator wire 26. Thereby, the secondary voltage U2 is applied to the stator coil 22.

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

[0034] The tappet 30 includes a tappet coil 32. During the linear motion process, the tappet coil 32 maintains a close arrangement with respect to the stator coil 22. The distance between the close arrangements of the tappet coil 32 and the stator coil 22 is from several millimeters to several centimeters.

[0035] The details of the tappet coil 32 can be confirmed in the enlarged central portion of FIG. 1. The tappet coil 32 is also preferably a toroidal core coil provided with 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 bonding module 1. The tappet coil 32 includes a plurality of tappet coil windings 321. The tappet coil windings 321 are made of a conductive material such as copper. The number of the tappet coil windings 321 can be in the range of 5 to 10. It is preferable that the number of the first transformer coil windings 251 is equal to the number of the tappet coil windings 321.

[0036] The stator coil 22 and the tappet coil 32 exhibit the function of establishing mutual inductive coupling. For this purpose, the stator coil 22 and the tappet coil 32 are arranged relative to each other such that the tappet coil 32 completely surrounds the winding 221 of the stator coil 22 in a specific region within a plane perpendicular to the longitudinal axis A. The stator coil winding 221 protrudes through the central through hole 320 of the tappet coil 32 in the exemplary embodiment according to FIGS. 1 and 2.

[0037] In a toroidal core coil, the magnetic field lines of force proceed in a circular path inside the toroidal core coil. Thereby, the magnetic field lines of force of the stator coil 22 proceed exactly to the place where the magnetic field lines of force of the tappet coil 32 continue, and as a result, an optimal inductive coupling is obtained.

[0038] Therefore, the stator coil 22 and the tappet coil 32 are suitable for inducing an alternating 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 the tappet coil 32 also exhibit the function of a transformer. The stator coil 22 and the tappet coil 32 are suitable for converting the secondary voltage U2 of the stator coil 22 into the alternating 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 into the alternating voltage U3 of the tappet coil 32. When the number of the first transformer coil windings 251 is the same as that of the tappet coil windings 321, the alternating voltage U3 of the tappet coil 32 becomes 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 the first carrier frequency F1. The measurement data MD is introduced into the alternating 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 preferably used. The tappet electronic component 31 is suitable for introducing the measurement data MD into the primary voltage U1 by phase-modulating the first carrier frequency F1 of the alternating voltage U3 of the tappet coil 32. In this case, the first carrier frequency F1 is introduced into the secondary voltage U2 by the conversion of the alternating voltage U3, and the first carrier frequency F1 is introduced into the primary voltage U1 by the conversion of the secondary voltage U2. Then the stator electronic component 21 is suitable for demodulating the phase-modulated first carrier frequency F1 of the primary voltage U1, thereby extracting the 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 at least one of information on the sensitivity specification of the force transducer 40 or the measurement range specification of the tappet electronic component 31 regarding the tappet electronic component 31 and the force transducer 40. In the process of conversion, the tappet electronic component 31 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 alternating 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 and 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 extracting the alternating voltage U3 from the tappet coil 32 and using the alternating voltage U3 to supply power to the tappet electronic component 31 or the force 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 the tappet electronic component 31 amplifies the measured value MW within this measurement range during the conversion process. For this purpose, the stator electronic component 21 is suitable for introducing the control data SD into the alternating 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 alternating voltage U3 of the tappet coil 32, thereby extracting the control data SD from the alternating voltage U3 of the tappet coil 32 and using the control data SD to operate the tappet electronic component 31.
