Description

Dispositivo de desbloqueo de lentes durante su fabricación.Lens unlock device during your manufacturing.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un dispositivo de desbloqueo de lentes durante su fabricación que permite la separación del soporte y el material fundente de adhesión que bloquean la lente, una vez mecanizada y pulida.The present invention relates to a lens unlocking device during its manufacture that allows the separation of the support and the flux material from Adhesion that block the lens, once machined and polished.

Antecedentes de la invenciónBackground of the invention

Durante el proceso de fabricación de lentes para gafas y óptica en general se procede al mecanizado y pulido de un bloque de cristal o material óptico y posteriormente al tratamiento superficial mediante la aplicación de recubrimientos químicos entre otros pasos.During the lens manufacturing process for glasses and optics in general we proceed to the machining and polishing of a glass block or optical material and after treatment surface by applying chemical coatings between other steps

Para que el bloque de cristal se pueda sujetar firmemente durante el mecanizado se adhiere a un soporte mediante una capa de aleación o material fundente a baja temperatura, que presenta una gran tensión superficial, que es la responsable de la sujeción.So that the glass block can be held firmly during machining adheres to a support by a layer of low temperature alloy or melting material, which it presents a great surface tension, which is responsible for the subjection.

Una vez mecanizada la lente a partir del bloque de cristal se debe proceder a eliminar el soporte y la lámina protectora para la realización de los tratamientos químicos superficiales y acabado final. Para ello el soporte es eliminado mediante un golpe o impacto que debilita la tensión superficial que sujeta la aleación fundente, mientras que la lente es sujeta mediante una ventosa. Este proceso provoca que exista un gran riesgo de rotura de la lente ya mecanizada, que es delicada, y por tanto se puede provocar un gran rechazo de material por deterioro. Además, con el golpe el soporte sale despedido y es difícil de recoger para volverlo a utilizar.Once the lens is machined from the block glass should proceed to remove the support and the sheet protective for chemical treatments Superficial and final finish. For this, the support is removed. through a blow or impact that weakens the surface tension that holds the flux alloy, while the lens is clamped through a suction cup. This process causes a large risk of breakage of the already mechanized lens, which is delicate, and for so much can cause a great rejection of material due to deterioration. In addition, with the blow the support is dismissed and it is difficult to pick up for reuse.

En un procedimiento diferente de desbloqueo, se calienta el material fundente hasta su reblandecimiento y se desprende el soporte mediante un chorro de agua o líquido a presión proyectado lateralmente sobre dicho soporte. Sin embargo el uso de dicho chorro exige un gasto de líquido y una adecuación de la zona de desbloqueo considerable.In a different unlocking procedure, you will heats the flux material until it softens and it detach the support by means of a jet of water or pressurized liquid projected laterally on said support. However the use of said jet requires a liquid expense and an adaptation of the area considerable unlocking

Descripción de la invenciónDescription of the invention

El dispositivo de desbloqueo de lentes durante su fabricación, objeto de esta invención, presenta unas particularidades técnicas destinadas a facilitar dicha operación de desbloqueo, con una recuperación más cómoda del soporte y un menor riesgo de daño para las lentes.The lens unlocking device during its manufacture, object of this invention, presents some technical particularities intended to facilitate said operation of unlocking, with a more comfortable support recovery and a smaller risk of damage to the lenses.

En efecto, el dispositivo comprende al menos dos brazos articulados, con unas mordazas a modo de pinzas de sujeción del soporte durante el desbloqueo, y al menos una leva de acción lateral sobre la capa de material fundente, encontrándose por debajo de los brazos unos medios de recogida del soporte desprendido. Estos brazos están relacionados, por sus extremos libres preferentemente, mediante un muelle de tracción y un cilindro neumático o hidráulico de expansión para su movimiento.In effect, the device comprises at least two articulated arms, with jaws as a clamp of the support during unlocking, and at least one action cam lateral on the layer of flux material, found by under the arms means for collecting the support detached. These arms are related, by their ends preferably free, by means of a tension spring and a pneumatic or hydraulic expansion cylinder for its movement.

Así cuando la lente es transportada desde las operaciones anteriores se fija mediante las ventosas, e inferiormente el soporte se sujeta mediante las mordazas de los brazos. En esta posición, cada leva se introduce en la capa de material fundente y lo despega por deformación, al encontrarse previamente a una temperatura de reblandecimiento.Thus when the lens is transported from the Previous operations are fixed by suction cups, and inferiorly the support is held by the jaws of the arms. In this position, each cam is introduced into the layer of flux material and take it off by deformation, when found previously at a softening temperature.

Los brazos están relacionados por sus extremos libres mediante un muelle de tracción que los cierra sobre el soporte, y un cilindro hidráulico o neumático de expansión para su movimiento de apertura y dejar caer el soporte.The arms are related by their ends free by a traction spring that closes them on the support, and a hydraulic or pneumatic expansion cylinder for your Opening movement and drop the support.

El dispositivo comprende dos juegos de brazos, levas y medios de recogida de los soportes, para el desbloqueo de una pareja de lentes simultáneamente, ya que las lentes se suelen mecanizar de dos en dos. Los dos juegos de brazos se encuentran articulados respecto a un único eje vertical de soporte común, para ello cada brazo presenta un aro de acoplamiento o similar que está desplazado respecto al plano de trabajo superior.The device comprises two sets of arms, cams and means for collecting the supports, for unlocking a pair of lenses simultaneously, since the lenses are usually Machining two by two. The two sets of arms meet articulated with respect to a single vertical axis of common support, for each arm has a coupling ring or similar that is displaced from the upper work plane.

Los medios de recogida del soporte desprendido están constituidos por una mesa sensiblemente horizontal, en la que se encuentra definida una ventana, sobre la que está dispuesta una trampilla de cierre, movida por medios mecánicos. Estos medios mecánicos pueden estar configurados, por ejemplo, por un cilindro hidráulico o neumático. Con esta disposición se facilita el control de los soportes desprendidos y se evita que la posible caída de la lente la pueda dañar.The means of collecting the detached support they consist of a substantially horizontal table, in which a window is defined, on which a closing hatch, moved by mechanical means. These means mechanics can be configured, for example, by a cylinder hydraulic or pneumatic With this provision the control is facilitated of the detached supports and prevents the possible fall of the Lens can damage it.

Cada leva de desbloqueo está dispuesta sobre un eje fijado a la mesa inferior. Esta leva está conectada con un cilindro hidráulico o neumático para su accionamiento, por ejemplo a través de un brazo lateral, que la hace girar. Para facilitar el despegue del material fundente se ha previsto que las levas estén calefaccionadas, aportando así calor a dicho material fundente al contacto.Each unlocking cam is arranged on a shaft fixed to the lower table. This cam is connected to a hydraulic or pneumatic cylinder for actuation, for example through a side arm, which rotates it. To facilitate the take off of the flux material the cams are expected to be heated, thus providing heat to said flux material to the Contact.
