La figura 1 es una vista en perspectiva del nuevo dispositivo en funcionamiento.Figure 1 is a perspective view of the New device in operation.
Las figuras 2 y 3 son vistas en alzado y en planta, respectivamente, el propio dispositivo de transferencia.Figures 2 and 3 are elevation views and in plant, respectively, the device itself transfer.
Los elementos designados con números en los dibujos corresponden a las partes indicadas a continuación.The designated elements with numbers in the Drawings correspond to the parts indicated below.
Las células solares, en el caso del ejemplo representado, son unas piezas 1 en forma de placas cuadrangulares de vértices biselados, preparadas en fases anteriores del proceso de fabricación, no reivindicado aquí.Solar cells, in the case of the example represented, are 1 pieces in the form of quadrangular plates of beveled vertices, prepared in earlier stages of the process of manufacturing, not claimed here.
En dicho proceso, las células se someten a unos baños y tratamientos químicos, para lo cual se disponen en unos soportes o casetes 2 de material plástico adecuado para resistir las acciones de dichos tratamientos.In said process, the cells undergo some baths and chemical treatments, for which they are arranged in some 2 stands or cassettes of plastic material suitable to resist the actions of such treatments.
Posteriormente, las células deben transferirse de los casetes 2 a unas barquillas 3 de cuarzo en orden a su introducción en hornos de tratamiento térmico, a temperaturas del orden de los 800ºC, empleándose el cuarzo por su conocida resistencia a la acción del calor.Subsequently, the cells must be transferred from cassettes 2 to quartz wafers 3 in order of introduction in heat treatment furnaces, at temperatures of order of 800ºC, using quartz by its known resistance to heat action.
Los casetes 2 consisten en unas cajas ortogonales cuyas caras internas, laterales y enfrentadas, presentan unas ranuras 4 horizontales y separadas a distancias correspondientes al espesor de las células 1. Dichas ranuras son de sección preferentemente angular o trapecial para facilitar la colocación y extracción de las células en orden a su tratamiento químico.Cassettes 2 consist of boxes orthogonal whose internal, lateral and facing faces, they have 4 horizontal slots and separated at distances corresponding to the thickness of the cells 1. These slots are of preferably angular or trapecial section to facilitate the placement and removal of cells in order of treatment chemical.
Las barquillas 3 consisten asimismo en unas cajas elementales definidas por montantes 5 y travesaños 6 de cuarzo. En los montantes existen unas ranuras horizontales 6 análogas a las 4 de los casetes 2.The wafers 3 also consist of elementary boxes defined by uprights 5 and crossbars 6 of quartz. In the uprights there are horizontal slots 6 analogous at 4 of the cassettes 2.
El objeto del dispositivo de la invención es transferir las células 1 de los casetes 2 a las barquillas 3 automáticamente.The object of the device of the invention is transfer the cells 1 of the cassettes 2 to the nozzles 3 automatically.
Para ello, el dispositivo cuenta con un elemento empujador, consistente en una larga placa rectangular 7 que tiene un movimiento de desplazamiento horizontal alternativo en la dirección del casete 2 a la barquilla 3 y viceversa. La placa 7 es impulsada por un mecanismo accionador, no reivindicado aquí y guiada en su desplazamiento mediante un sistema de guías que incluye, por ejemplo, unas hendiduras longitudinales 8.For this, the device has an element pusher, consisting of a long rectangular plate 7 that has an alternative horizontal scrolling movement in the Address of cassette 2 to booth 3 and vice versa. Plate 7 is driven by an actuator mechanism, not claimed here and guided in its movement through a system of guides that it includes, for example, longitudinal grooves 8.
El empujador 7 y su mecanismo accionador son de gran precisión, dado que deben operar sin problemas funcionales con piezas (las células solares) de muy reducido espesor, extraerlas de los casetes y colocarlas en las barquillas.The pusher 7 and its drive mechanism are of high precision, since they must operate without functional problems with pieces (solar cells) of very small thickness, remove them from the cassettes and place them in the wafers.
El funcionamiento del dispositivo descrito es como sigue:The operation of the described device is as follows:
El empujador 7 hace desplazar sucesivamente las células 1 desde los casetes 2 a las barquillas 3, según una carrera correspondiente a la dimensión longitudinal de las células, extrayéndolas de las ranuras 4 e introduciéndolas seguidamente en las ranuras 6. Una vez realizada la transferencia, el empujador 7 retrocede y un mecanismo elevador (no representado) hace ascender la barquilla 3, volviéndose a enfrentar aquellos elementos hasta que se ha transferido la totalidad de las células.The pusher 7 causes successively to move the 1 cells from cassettes 2 to nozzles 3, according to a race corresponding to the longitudinal dimension of the cells, removing them from slots 4 and then entering them into the slots 6. Once the transfer is made, the pusher 7 goes back and a lifting mechanism (not shown) ascends the nozzle 3, facing those elements until that all the cells have been transferred.
Este sistema permite una gran flexibilidad en cuanto al número de células, a su espesor y distancia entre ellas. Asimismo es adaptable a distintas formas y tamaños de las células.This system allows great flexibility in as for the number of cells, their thickness and distance between them. It is also adaptable to different shapes and sizes of cells.
