Definitions

  • the invention relates to a process and a device for form locked joining of two components and to a device for performing the process.
  • a possibility to establish disengageable connections is using threaded connections.
  • the disadvantage of this process is that the housing then has to be provided with a thread.
  • a threaded metal insert is therefore often integrated during the injection molding process in order to obtain a load bearing thread. Consequently, manufacturing a respective connection is very expensive.
  • non disengageable connection techniques e.g. encasing the printed circuit board in the housing or so-called hot caulking are being used.
  • a rod shaped component briefly also called pin
  • the pin is run through a hole in the printed circuit board, so that it rests on a shoulder.
  • the pin protruding beyond the thickness of the printed circuit board is deformed under thermal energy, so that the pin forms a rivet head for form locked fixation of the printed circuit board.
  • a respective process using ultrasound energy for generating the necessary heat is described in DE 4215041 C3 (Siemens AG).
  • JP 62064528 A Toyota Motor Corp.
  • radiation energy is used to achieve the plastic state of one of the joining partners.
  • the hot caulking processes according to the state of the art have the disadvantage that forming the rivet head is being performed through a contact tool. When using such processes for hot caulking of plastic housings or printed circuit boards, this bears the risk of material sticking to the shaping tool.
  • the media tight closing of the housing is an important part of the value creation process of mechatronic systems.
  • laser through transmission welding is industrially established.
  • two joining partners which can be welded through melting, are being combined, one of which has a high degree of optical transmission for the wavelength of the welding laser that has been used, and however, the other joining partner strongly absorbs this wavelength.
  • the welding radiation can transmit through the joining partner facing it and is subsequently absorbed at the contact surface of the two components.
  • the absorbing joining partner is being heated until both joining partners are melted in their contact area through heat conduction.
  • the object of the present invention is to provide a reliable and error tolerant process for form locking connection of two components, which does not have the disadvantages of the current state of the art processes. Furthermore, it is part of the object of the invention to perform the form locking connection of two components simultaneously with the adhesive bonding of a third component, in order to integrate two process steps, and to thereby achieve a cost saving shortening of the process chain.
  • a third component in order to achieve the object, it is suggested according to the invention, to create the form locking connection between a first and a second component through plastic deformations of the first component by a third component.
  • the third component thereby, does not have to be in contact with the second component, it is rather being used to plastically deform the first component, so that a form locking connection between the first and the second component can occur.
  • the third component preferably enters into an adhesive bond with the first component, while establishing the form locking connection between the first and the second component.
  • the invention is characterized in that the plastic deformation to achieve form locking is generated through a third component participating in the joining process, which by itself enters into an adhesive bond with one of the joining partners.
  • a respective process is used e.g. for mounting printed circuit boards in a housing made from thermoplastic plastic material.
  • the advantage of this procedure is that the tool, imparting the force for the plastic deformation, is not in direct contact with the plasticized component, so that an unwanted material adhesion on the tool can be avoided.
  • the invention thereby utilizes the state of the art trough transmission welding process, in order to create the adhesive bond between the first and the third respective component, each weldable through melting, preferably made from thermoplastic plastic material, and to provide the energy to transform the first component into a state, where it can be plastically deformed.
  • the invention is characterized in that, the first and the third component perform a feed motion relative to each other under the influence of a compression force during the welding process, according to the explanations in the state of the art, and that this feed motion is being used in order to produce the plastic deformation of the first component necessary for the form locking connection of the first and second component.
  • FIG. 1 is a schematic sectional view of a portion of three components to be connected to each other in a first process step according to a first embodiment of the invention
  • FIG. 2 is a schematic sectional view according to FIG. 1 in a second process step
  • FIG. 3 is a schematic sectional view of three components to be connected to each other according to a second embodiment of the invention.
  • FIG. 1 A first exemplary embodiment of the invention is illustrated in FIG. 1 .
  • the radiation absorbing joining partner ( 1 ) is depicted as a cutout, e.g. from an electronics housing.
  • a pass-through hole ( 5 ) of the component ( 2 ) to be connected in a form locking manner, e.g. a printed circuit board, a column shaped riser ( 4 ), also called a pin, reaches through in the non joined state.
  • An additional component ( 3 ) is placed onto this pin, initially in a loose manner, which is sufficiently transparent for the imparted welding radiation ( 6 ).
  • the radiation transmitting component ( 3 ) has a concave cross section ( 7 ) in the contact area with the pin, which supports the creation of the material flow of the absorbing component ( 1 ) during the plastic deformation.
  • the radiation transmitting component is pressed down onto the pin ( 4 ) through a down holder ( 10 ) mounted coaxial with the welding radiation. After the pin ( 4 ) has been exposed to the welding radiation ( 6 ) for a certain amount of time, and has been imparted with the compression force through the down holder ( 10 ), a plastic deformation of the pin ( 4 ) with a lateral material flow occurs, so that the assembly shown in FIG. 2 is created at the end of the process.
  • material of the pin ( 4 ) is plasticized through the heating of the welding radiation, until it is displaced laterally under the influence of the compression force, so that cooler material layers of the pin are exposed again to the radiation and can be heated.
  • the down holder element ( 10 ) can perform a constant feed motion in the direction of the absorbing joining partner ( 1 ).
  • the concave indentation in the transmissive joining partner ( 7 ) supports the formation of the rivet head ( 8 ), necessary for the form locking connection, during the feed motion by determining the flow direction of the material.
  • the joining partner ( 2 ) to be joined through form locking is connected in a solid manner with the absorbing joining partner ( 1 ). Since the pin ( 4 ) is made from laser absorbing material, however, the initially loosely placed component ( 3 ) transmits the welding radiation ( 6 ), heat generation and adhesively bonded welding finally occurs at the contact surface of the two components.
  • FIG. 3 A particularly advantageous embodiment of the process according to the invention is shown in FIG. 3 before the joining process.
  • the transmissive component which produces the plastic deformation of the pin ( 4 )
  • the transmissive component is a component of the complete assembly at the same time, which has further functions besides creating form locking.
  • the cover of an electronics housing ( 13 ) which is supposed to close the housing tight against media, can simultaneously be used for forming the rivet head.
  • the radiation field of the welding radiation ( 6 ) is run along a welding bar ( 11 ), as described in the state of the art literature.
  • the control means of the device for performing the process allow that, besides the welding bar ( 11 ), also the pin ( 4 ) is radiated within a short time interval from the radiation of the welding bar.
  • a compression force which is imparted along the circumferential welding rim with the assistance of a compression frame ( 12 ) onto the component cover ( 13 ) and the welding rim ( 11 )
  • a feed motion of the compression frame ( 12 ) and the housing cover ( 13 ) occurs in the direction of the radiation absorbing joining partner ( 1 ).
  • the process of media tight welding is decoupled from the creation of the hot caulk with respect to the geometric tolerances of the components.
  • the third component ( 13 ) were directly used for form locking mounting of the printed circuit board ( 2 )
  • typical manufacturing tolerances of the components could cause the housing cover ( 13 ) to already make contact with the printed circuit board, before the welding rim ( 11 ) has been melted down by the desired height.
  • the welding rim ( 11 ) and the pin ( 4 ) could already be melted down by a predetermined value, so that the entire joining process is terminated without the printed circuit board ( 2 ) being firmly pressed against the lower joining partner ( 1 ).
  • the creation of form locking according to the invention through the displaced material of the pin ( 4 ) as a component of the lower joining partner eliminates this problem.
