Problems solved by technology

While individual contact lens presence checks are possible on the packaging line, it may happen that the contact lens is not released from the gripper despite excessive pressure, resulting in the package not containing the lens and thus The said package and any additional packages associated therewith must be sorted out and cannot be sold

Embodiment Construction

[0029] figure 1 An embodiment of a gripper 1 according to the invention is shown. The gripper 1 comprises a gripper head 10 having a bearing surface 11 in which there are a plurality of openings 110 through which negative pressure can be applied in order to hold the contact lens CL (see figure 2 ) onto the carrying surface 11, or overpressure can be applied through the opening in order to release the contact lens from the carrying surface 11. Furthermore, a detection opening 111 is provided in the carrier surface 11 , through which a separate negative pressure can be applied. The bearing surface 11 is a smooth surface that does not include any channels, grooves or the like, so that the contact lenses adhere properly to the bearing surface 11 when they are sucked onto the bearing surface by negative pressure. exist figure 1 In the illustrated embodiment of the gripper 1 , the openings 110 , through which a negative pressure or an overpressure can be applied, comprise a cent...

Abstract

A gripper (1 ) for a contact lens (CL) comprises a gripper head (10) having a bearing surface (11 ), the bearing surface (1 1 ) having at least one opening (110) through which underpressure can be applied in order to suck the contact lens (CL) against the bearing surface (11 ) and through which overpressure can be applied in order to release the contact lens (CL) from the bearing surface (11 ). The gripper further comprises a detection opening (111) in the bearing surface (11 ) through which a separate underpressure can be applied.

Description

technical field [0001] The present invention relates to a gripper for contact lenses and a method for delivering contact lenses. Background technique [0002] Often in the automated production of contact lenses, especially in the production of high-volume contact lenses (as in the case of disposable lenses, for example), there is a need to be able to safely, quickly and efficiently manipulate contact lenses at certain points in the production process. An example of such manipulation of a contact lens is when the contact lens is removed from a test cell where it is placed in a liquid such as water in order to test the lens (e.g. by image processing). ). [0003] In order to remove tested contact lenses from such a testing chamber, a device called a gripper is used, which is also used at other stations of the production process. With the help of said gripper the contact lens is grasped and in the above example removed from the testing chamber. The contact lenses are then st...
