OBJETO DE LA INVENCIÓN.OBJECT OF THE INVENTION
La siguiente invención, según se expresa en el enunciado de la presente memoria descriptiva, consiste en un sistema de montaje y verificado de conjuntos funcionales para electrodomésticos, de forma que el conjunto funcional definido por el cableado y los componentes electromecánicos conexionados, es montado y verificado sobre el propio tablero de montaje del mismo, permitiendo detectar cualquier fallo en el cableado, en el conexionado o en los propios componentes, lo que facilita la corrección del fallo sobre el propio tablero de una forma sencilla y rápida, tratando de llegar a una calidad de cero errores.The following invention, as expressed in the statement of the present specification, consists of a system of assembly and verified of functional sets for household appliances, so that the functional set defined by the wiring and the connected electromechanical components, is assembled and verified. on the mounting board itself, allowing to detect any fault in the wiring, in the wiring or in the components themselves, which facilitates the correction of the fault on the board itself in a simple and fast way, trying to reach a quality of zero errors.
Así, el operario, sobre el tablero de montaje, configurará todo el conjunto funcional de que se trate, para lo cual dispondrá de todos los elementos y componentes necesarios en su puesto de trabajo, de manera que en primer lugar conformará o montará y conexionará el conjunto funcional de acuerdo a los paneles de instrucciones de que dispone, para finalmente realizar el verificado de todo el conjunto, tal como si el propio aparato al que va destinado el conjunto funcional estuviese en su funcionamiento normal, pudiendo comprobar todas las incidencias y secuencias del mismo.Thus, the operator, on the mounting board, will configure all the functional set in question, for which he will have all the necessary elements and components in his workplace, so that he will first form or assemble and connect the functional set according to the instruction panels available, to finally verify the entire set, as if the device to which the functional set is intended to be in normal operation, being able to check all the incidents and sequences of the same.
De esta forma, el operario que realiza el conjunto funcional, puede verificar que el mismo está correctamente montado, y que todos los componentes funcionaran correctamente, pudiendo entregar el conjunto funcional totalmente verificado para que no precise ninguna otra verificación adicional hasta que el mismo se encuentre montado en el aparato correspondiente, como un elemento más del mismo.In this way, the operator who performs the functional set, can verify that it is correctly assembled, and that all the components will work correctly, being able to deliver the fully verified functional set so that it does not require any additional verification until it is found mounted on the corresponding apparatus, as another element thereof.
CAMPO DE APLICACIÓN. El sistema de montaje y verificación de conjuntos funcionales , formado por el cableado y los componentes electromecánicos conexionados, será de aplicación en todos aquellos aparatos o máquinas que dispongan de una parte eléctrica que podrá ser verificado en el propio momento de su montaje, en la correspondiente fábrica, para poder detectar cualquier posible error producido en el conjunto funcional en el momento de su montaje "in situ". Así, el conjunto funcional será posible adaptarlo para todos aquellos aparatos o máquinas que incorporen una parte eléctrica, y el mismo podrá estar destinado, preferentemente, para aparatos electrodomésticos de uso en el hogar así como para cualquier otra industria. ANTECEDENTES DE LA INVENCIÓN.SCOPE. The assembly and verification system of functional assemblies, formed by the wiring and the connected electromechanical components, will be applicable in all those devices or machines that have an electrical part that can be verified at the moment of its assembly, in the corresponding factory, to be able to detect any possible error produced in the functional set at the time of its assembly "in situ". Thus, the functional set will be able to adapt it for all those devices or machines that incorporate an electrical part, and it may be used, preferably, for household electrical appliances as well as for any other industry. BACKGROUND OF THE INVENTION
Convencionalmente, cada vez con una mayor frecuencia, los fabricantes de distintos aparatos, en lugar de realizar en sus propias instalaciones el montaje completo de todos los elementos que componen el mismo, realizan la subcontratación de diferentes partes a otras industrias especializadas del sector correspondiente, con objeto de obtener una gran calidad en su producto, a la vez que se reduce el proceso de industrialización en la línea de montaje.Conventionally, each time with a greater frequency, the manufacturers of different devices, instead of carrying out in their own facilities the complete assembly of all the elements that make up the same, make the subcontracting of different parts to other specialized industries of the corresponding sector, with in order to obtain high quality in your product, while reducing the industrialization process in the assembly line.
Así, entre los elementos subcontratados habituaimente, podemos citar los cableados del conjunto eléctrico de diferentes aparatos o máquinas, de manera que Empresas especializadas efectúan el montaje del cableado en sí, que es servido al fabricante para que en el proceso industrial de montaje del correspondiente aparato se incluya dicho cableado como un componente más para conexionar el mismo con los respectivos componentes.Thus, among the subcontracted elements usually, we can cite the wiring of the electrical set of different devices or machines, so that specialized Companies carry out the assembly of the wiring itself, which is served to the manufacturer so that in the industrial process of assembly of the corresponding apparatus said wiring is included as another component to connect it with the respective components.
De esta forma, la Empresa especializada que efectúa el cableado recibe los cables en grandes bobinas, de acuerdo a distintos colores y sección del hilo, de manera que en primer lugar se produce el corte de los distintos cables deseados a la longitud necesaria, siendo pelados y montados o engastados los terminales en los extremos de los mismos, efectuándose dichas operaciones automáticamente, ya que incluso los terminales son servidos en correspondientes bobinas, para que la propia máquina sea la que realice dicha operación.In this way, the specialized company that carries out the wiring receives the cables in large coils, according to different colors and section of the wire, so that first of all the desired cables are cut to the necessary length, being stripped and mounted or crimped the terminals at the ends thereof, said operations being performed automatically, since even the terminals are served in corresponding coils, so that the machine itself is the one to perform said operation.
Asimismo, en caso de ser necesario se realizan premontajes agrupando determinados cables y disponiendo elementos, tales como conectores u otros componentes, si así es necesario. A continuación se realiza el montaje del cableado de acuerdo al manual de instrucciones y se verifica eléctricamente. Esto es, se comprueba que la disposición de los mismos es la correcta y que eléctricamente se ha definido el circuito correcto. Por último, en el montaje del conjunto funcional, esto es, que el cableado se conexione a los distintos componentes electromecánicos la única verificación realizada es la visual del conexionado, con lo cual los errores pueden ser relativamente frecuentes lo que acarrea una serie de graves problemas posteriores.Also, if necessary, pre-assemblies are made by grouping certain cables and arranging elements, such as connectors or other components, if necessary. The wiring assembly is then carried out according to the instruction manual and electrically verified. That is, it is verified that their arrangement is correct and that the correct circuit has been electrically defined. Finally, in the assembly of the functional set, that is, that the wiring is connected to the different electromechanical components, the only verification performed is the visual one of the wiring, with which the errors can be relatively frequent, which leads to a series of serious problems later.
Así, al ser montado el conjunto funcional en el aparato por el fabricante final, al verificar el correcto funcionamiento de éste, una vez que está totalmente montado, es cuando se detectan errores de funcionamiento, tanto por un mal conexionado como por defectos internos de algún componente, por lo que se debe desmontar el aparato para corregir el error, lo cual requiere la inversión de un considerable tiempo y consecuentemente un alto coste económico.Thus, when the functional assembly is mounted on the device by the final manufacturer, when verifying its correct operation, once it is fully assembled, it is when operating errors are detected, both due to a bad connection and internal defects of some component, so the device must be disassembled to correct the error, which requires considerable time investment and consequently a high economic cost.
De esta forma, se trata de evolucionar de manera tal, que manteniendo una gran competitividad y calidad de servicio, se llegue al punto de cero defectos, para lo cual se debe realizar una total verificación del conjunto funcional con anterioridad al propio montaje en el producto final, como un componente más del aparato.In this way, it is about evolving in such a way that maintaining a great competitiveness and quality of service, the point of zero defects is reached, for which a total verification of the functional set must be carried out prior to the assembly itself in the product final, as another component of the device.
DESCRIPCIÓN DE LA INVENCIÓN. En la presente memoria se describe un sistema de montaje y verificado de conjuntos funcionales para electrodomésticos, entendiendo por conjunto funcional el cableado y los componentes electromecánicos conexionados al mismo, el cual puede formar parte de cualquier aparato o máquina que conlleve una parte eléctrica, de forma que el cableado es conformado a partir de los cables ya preparados (cortados a medida y engastados los cables y terminales), sobre un tablero, en base a los correspondientes paneles de instrucciones, incorporando el cableado en sí, sobre el propio tablero, provisto de las respectivas contrapiezas de todos los componentes electromecánicos conexionados al mazo de cables.DESCRIPTION OF THE INVENTION This report describes a system for assembling and verifying functional assemblies for household appliances, the functional set being understood as the wiring and electromechanical components connected thereto, which can be part of any device or machine that carries an electrical part, so that the wiring is formed from the cables already prepared (cut to size and crimped the cables and terminals), on a board, based on the corresponding instruction panels, incorporating the wiring itself, on the board itself, provided with the respective counter parts of all electromechanical components connected to the harness.
Así, sobre el propio tablero, se disponen los componentes electromecánicos conexionados al mazo de cables, en las correspondientes contrapiezas para la sujeción y accionamiento de los citados componentes para lo cual el tablero dispone de las respectivas acometidas eléctricas, mecánicas y neumáticas, para poder actuar sobre todos los componentes simulando la funcionalidad real del conjunto.Thus, on the board itself, the electromechanical components connected to the cable harness are arranged, in the corresponding counter parts for the clamping and actuation of said components for which the board has the respective electrical connections, mechanical and pneumatic, to be able to act on all the components simulating the real functionality of the set.
Asimismo, el sistema dispone de los medios necesarios para la verificación del conjunto funcional, esto es del cableado, del conexionado de este con los distintos componentes electromecánicos, así como de los propios componentes.Likewise, the system has the necessary means to verify the functional set, that is, the wiring, its connection with the different electromechanical components, as well as the components themselves.
De esta forma, una vez que el conjunto funcional ha sido conformado y se han conexionado aquellos componentes electromecánicos, que así lo requieren al cuadro electroneumático e hidráulico, se procederá al verificado del conjunto funcional por medio del microprocesador que incorpora el sistema y los elementos interrelacionados con él, como son un ordenador, un teclado, una impresora, un monitor, e incorporando todas aquellas tarjetas de control que sean necesarias de acuerdo a la verificación a realizar, tanto del sistema en sí como del conjunto funcional. El sistema de montaje y verificado es un sistema totalmente abierto adaptable para el conformado de conjuntos funcionales diversos, los cuales podrán incorporar distintos componentes electromecánicos, permitiendo una rápida modificación de éste para adaptarse a cualquier nueva distribución del conjunto, así como a la incorporación de nuevos componentes. Para llevar a cabo la precisa verificación del conjunto funcional, en la memoria del microprocesador se han introducido las secuencias relativas a la función a realizar por el conjunto a verificar, de manera que cuando los valores obtenidos se correspondan con los introducidos en la memoria será aceptado, mientras que si los valores obtenidos no se corresponden con los de las secuencias memorizadas, aparecerá el error en el monitor para que el mismo pueda ser corregido, presentándose las indicaciones o pasos a seguir para solucionarlo.In this way, once the functional set has been shaped and those electromechanical components have been connected, which require it to the electropneumatic and hydraulic panel, the functional set will be verified by means of the microprocessor that incorporates the system and the interrelated elements with it, such as a computer, a keyboard, a printer, a monitor, and incorporating all those control cards that are necessary according to the verification to be performed, both of the system itself and of the functional set. The assembly and verified system is a fully open system adaptable for the conformation of diverse functional assemblies, which may incorporate different electromechanical components, allowing a rapid modification of this to adapt to any new distribution of the assembly, as well as the incorporation of new components. To carry out the precise verification of the functional set, the sequences related to the function to be performed by the set to be verified have been introduced into the microprocessor's memory, so that when the values obtained correspond to those entered in the memory it will be accepted , while if the values obtained do not correspond to those of the memorized sequences, the error will appear on the monitor so that it can be corrected, presenting the indications or steps to follow to solve it.
Así, una vez detectado el error, el operario únicamente deberá comprobar a que causa, en concreto, se debe el fallo, bien si es del cableado, del conexionado o del propio componente correspondiente al elemento en el que se ha detectado el error, procediendo según convenga.Thus, once the error has been detected, the operator must only verify to what cause, in particular, the fault is due, whether it is the wiring, the wiring or the component corresponding to the element in which the error has been detected, proceeding as required.

Así, todo el control no está destinado únicamente a lo que es el conjunto funcional, sino a lo que es el sistema general para la ejecución del verificado. El sistema verifica el funcionamiento de todos y cada uno de los componentes que forman parte del conjunto funcional y su correcto posicionado a través de un cableado, así como la distribución espacialThus, all the control is not only destined to what is the functional set, but to what is the general system for the execution of the verified. The system verifies the operation of each and every one of the components that are part of the functional set and its correct positioning through a wiring, as well as the spatial distribution
(medidas cableado y posicionado componentes que corresponda al conjunto seleccionado).(measures wiring and positioning components corresponding to the selected set).
Así, se introduce en el ordenador las secuencias (pasos) que se tienen que realizar para la verificación del conjunto funcional (producto). Estas secuencias variarán de acuerdo a las características o composición de cada conjunto. Una vez elegido el conjunto funcional que se va a fabricar, se envían todas las secuencias necesarias para su verificación al equipo de control , que será el encargado de gestionar todas las acciones, tanto electromecánicas como electrónicas que han de llevarse a cabo para la verificación. Una vez realizadas satisfactoriamente todas las secuencias se imprime una etiqueta donde aparecen todas las indicaciones precisas para la correcta identificación y trazabilidad del producto (denominación del producto, orden de fabricación, fecha, operario, valores obtenidos en determinadas pruebas sobre los componentes, etc. todo ello en caracteres alfanuméricos y/o código de barras).Thus, the sequences (steps) that have to be performed for the verification of the functional set (product) are entered into the computer. These sequences will vary according to the characteristics or composition of each set. Once the functional set to be manufactured has been chosen, all the sequences necessary for verification are sent to the control team, which will be in charge of managing all the electromechanical and electronic actions that must be carried out for verification. Once all the sequences have been successfully completed, a label is printed showing all the precise indications for the correct identification and traceability of the product (product name, manufacturing order, date, operator, values obtained in certain tests on the components, etc. all this in alphanumeric characters and / or barcode).
El microprocesador tras leer la secuencia que tiene que realizar, da las ordenes pertinentes para realizar la prueba indicada en ella. Por un lado, realiza las acciones electromecánicas oportunas para colocar los diversos componentes del conjunto en la situación que se ha decidido para esta comprobación. Estas acciones (ordenes) podrán afectar directamente a elementos o útiles incorporados en el tablero de conformación y verificación, como a elementos intermedios (válvulas del equipo electroneumático) que a su vez actuarán sobre los útiles indicados anteriormente. Una vez realizadas todas estas acciones, realiza lo que sería la verdadera verificación o testeo indicado en esa secuencia del proceso (programa) de verificación.The microprocessor, after reading the sequence to be performed, gives the relevant orders to perform the test indicated on it. On the one hand, it performs the appropriate electromechanical actions to place the various components of the assembly in the situation that has been decided for this check. These actions (orders) may directly affect elements or tools incorporated in the conformation and verification board, as well as intermediate elements (valves of the electropneumatic equipment) that in turn will act on the tools indicated above. Once all these actions have been carried out, perform what would be the true verification or testing indicated in that sequence of the verification process (program).
En caso de no obtener un valor o valores conforme con lo indicado en la secuencia, se emite un mensaje en el monitor 2 de error en el que aparecen las indicaciones o pasos a seguir para solucionarlo. Una vez que el operario ha realizado lo indicado en pantalla el sistema vuelve a realizar la secuencia en la que se había detenido. Si en ese momento obtiene una respuesta positiva el sistema sigue adelante con la verificación, y en caso contrario rechazará la instalación.In case of not obtaining a value or values in accordance with what is indicated in the sequence, a message is emitted in the error monitor 2 in which the indications or steps to be followed to solve it appear. Once the operator has done what is indicated on the screen the system returns to the sequence in which it had stopped. If at that time you get a positive response on system proceeds with verification, otherwise it will reject the installation.
En definitiva, las mediciones que se realizan son las siguientes:In short, the measurements made are the following:
I. Medición de continuidad: El microprocesador conecta los puntos indicados en la secuencia a la tarjeta de control de tensión para comprobar que se ha cerrado el circuito.I. Continuity measurement: The microprocessor connects the points indicated in the sequence to the voltage control card to verify that the circuit has been closed.
II. Medición de intensidad, tensión o resistencia: Se aplica la tensión necesaria los puntos indicados en la secuencia, y a través de la tarjeta de control de medición leemos el valor obtenido. III. Medición de presión: Mediante la tarjeta de control de presión y la de control de salidas se accionan los elementos necesarios para introducir la presión adecuada a los componentes del conjunto que sea preciso hacerlo. IV. Medición luminosidad: El microprocesador activa las tarjetas correspondientes para aplicar una tensión en los puntos indicados en la secuencia y verificar la actuación fotoeléctrica del componente que lo requiera. Todas estas acciones de medición y de actuación del sistema sobre el conjunto a verificar se realizan a través de las tarjetas de control 24 de los convertidores A/D y D/A que actúan como si de un interprete se tratara entre laII. Current, voltage or resistance measurement: The necessary voltage is applied to the points indicated in the sequence, and through the measurement control card we read the value obtained. III. Pressure measurement: With the pressure control card and the output control card, the necessary elements are activated to introduce the appropriate pressure to the components of the assembly that must be done. IV. Luminosity measurement: The microprocessor activates the corresponding cards to apply a voltage at the points indicated in the sequence and verify the photoelectric performance of the component that requires it. All these actions of measurement and action of the system on the set to be verified are carried out through the control cards 24 of the A / D and D / A converters that act as if it were an interpreter between the
CPU que controla el equipo y las señales que se envían a todos los elementos que rodean el sistema.CPU that controls the equipment and the signals that are sent to all the elements that surround the system.
Por otra parte, el sistema puede funcionar de forma autónoma o estar integrado en una red de puestos de trabajo, controlados desde un ordenador central (servidor), es decir, cada puesto de trabajo puede tener grabados en su memoria ios programas necesarios para verificar los conjuntos funcionales que en ese puesto vayan a ser montados y verificados, y será el propio operario desde el mismo puesto quien elija y cargue el programa que corresponda en cada momento. Por el contrario, conectando todos los puestos a un sistema de red, será el encargado de la planta quien decidirá qué instalación (conjunto funcional) se monta y verifica en cada puesto de trabajo, enviando desde el servidor- controlador del sistema el programa de secuencias de verificación que cada puesto necesita.On the other hand, the system can operate autonomously or be integrated into a network of workstations, controlled from a central computer (server), that is, each workstation can have the necessary programs recorded in its memory to verify the functional sets that in that position will be assembled and verified, and it will be the operator himself from the same position who chooses and loads the corresponding program at any time. On the contrary, connecting all the posts to a network system, it will be the plant manager who will decide which installation (functional set) is mounted and verified in each workstation, sending from the server- system controller the sequence of verification program that each position needs.
Trabajando de esta forma, se conoce en tiempo real la cantidad producida de cada referencia (producto), permitiendo reaccionar rápidamente según las necesidades de producción, además de controlar perfectamente la trazabilidad de cada orden de fabricación.Working in this way, the quantity produced of each reference (product) is known in real time, allowing to react quickly according to the production needs, in addition to perfectly controlling the traceability of each production order.
De esta forma, el fabricante del aparato en el que se incorpora el conjunto funcional correspondiente, monta el citado conjunto funcional como un componente más del aparato, no necesitando realizar verificación alguna sobre el mismo, ya que previamente se ha realizado la verificación del cableado, conexionado y de los componentes, para asegurar su perfecto funcionamiento, dado que aunque los componentes sean verificados en origen, puede ocurrir que durante su transporte o manipulación puedan sufrir alguna anomalía. En definitiva, mediante la verificación del conjunto funcional tal como se ha especificado, se trata de reducir el número de errores a cero, para que el fabricante incorpore el mismo como un elemento más del conjunto, sin realizar verificación intermedia alguna, y únicamente realizar una verificación rutinaria final del aparato, evitando así tener que paralizar la cadena de montaje, o desmontar los aparatos al detectar un fallo de funcionamiento cuando el mismo está totalmente montado con el importante coste económico de mano de obra que ello conlleva. In this way, the manufacturer of the apparatus in which the corresponding functional assembly is incorporated, assembles the said functional assembly as one more component of the apparatus, not needing to perform any verification on it, since the wiring verification has previously been carried out, connection and components, to ensure its perfect operation, since although the components are verified at source, it may happen that during transport or handling they may suffer some anomaly. In short, by verifying the functional set as specified, it is a question of reducing the number of errors to zero, so that the manufacturer incorporates the same as another element of the set, without performing any intermediate verification, and only performing a final routine verification of the device, thus avoiding having to paralyze the assembly line, or disassembling the devices when detecting a malfunction when it is fully assembled with the significant economic cost of labor that entails.
