- the present invention relates to a wire handling device, to an insertion procedure one end of a section of a wire line into a Socket of a connector and onto an insertion machine, which contains such a handling device.
- the technical field of the invention is that of Manufacture of automatic machinery for manufacturing of harnesses.
- the US 5,615,478 describes various types of Handling pliers for electrically conductive wire sections, their integration in wire bundle preparation machines as well as a method and an apparatus for inserting wire ends into sockets of connectors or similar electrical components.
- the present invention has for its object such improved pliers, insertion procedures and devices propose.
- An object of the invention is to be reliable and propose inexpensive system that is quality the insertion of a wire into a socket of a component regardless of whether the wire is previously - through Crimping or the like - connected with a cable lug has been systematically checked or not.
- the sensors made of piezoelectric ceramic, their sensitivity on the order of 100 or more 100 pico-coulombs / newtons when used for measurement a crimping force are provided - which in general is greater than 2000 Newtons - are for measuring one Importer - which is generally in one area is from 1 to 100 Newtons, badly suited.
- the signals provided by the piezoelectric sensors are also often disturbed when the Organs - such as connectors and wire lines - for the connection of the sensor with an electronic device for the Processing of signal supplied by the sensor - for example a charge amplifier - subject to movements; these movements can namely parasitic electrical Charges in particular due to the triboelectric effect produce; therefore it is difficult to use such sensors use "embedded" in moving parts of the machine (assembled); this point becomes special important as soon as the results of the force measurement as Criterion for evaluating the quality of the concerned (Introductory) operation can be used.
- a wire handling device suggested the one body and one Wire-holding member that is movably attached to the body is, the wire holding member is a sensor for a force exerted by this organ is sensitive.
- the invention proposes pliers for insertion one end of a wire line into a socket Connector that includes a body and an arm, which is provided with a wire jaw and with respect is movably attached to the body, with the arm a piezoelectric sensor for measuring a Has introductory force.
- the sensitivity of the sensor for inserting the end in a jack requires increased force while at the same time the sensitivity of the sensor to parasitic Forces resulting in particular from inertial effects and mechanisms for moving and opening the pliers (the Handling device) result, is reduced.
- the sensor preferably contains two rings - or thin ones Parts in plate or disc form - from a polarized Ceramic material that are completely the same, side by side are attached and between two parallel Areas of two parts leading to the arm or handling organ belong, are preloaded; this enables the Execution of a simple and compact sensor in which each disc for compressive forces of the ring as well as for axial Strain forces of the disc is sensitive; this makes possible thus measuring an insertion force (conventionally positive) as well as a force in opposite Direction (and with opposite sign); this thus enables the measurement of a tensile force on the Wire is exercised after its introduction to check that the introduction was correct and complete, especially in the case of insertion into a jack Cable lug, which is provided with locking tongues.
- an equipotential surface conductor provides; a first equipotential surface, which is the positive pole of a first sensitive Element with the negative pole of a second sensitive Element connects, and a second equipotential surface, which are sensitive to the negative pole of the first Element with the positive pole of the second sensitive Elements connects; every equipotential surface is preferably - via a coaxial conductor - with a corresponding input of a charge amplifier connected, which changes the charge of the sensor into a voltage or convert a current; this enables in particular reducing the number of electrical connections on the input side of the amplifier and allows consequently the limitation of the interference of the measurement signal, that could result from a leakage current that results from these connections.
- the pliers or the handling device have two arms or wire holding members - which are generally in are movably attached to the body - is preferably each of them with a force sensor Mistake; this is made possible by summing the measurement signals, increase the sensitivity of the whole; This can with an OR operation that replaces the summation and is exerted on the two measurement signals, also the Taking advantage of redundancy of the sensors enables what increases the reliability of the implementation control system; also allows the use of more sensitive Elements, especially at least three or four sensitive elements, by differential Measurements to determine multiple force components, and can therefore enable the direction to be determined from it.
- the sensor is preferably made with piezoelectric ceramic used whose output with a charge amplifier is connected, the input and / or the output of the Amplifier to zero before each insertion operation is reset to remove residual charges that arising from the previous introductory operation and / or from one or more gripping movements and / or the Approach the cable lug or the wire end could.
