Problems solved by technology

Although such a method can reduce the damage caused by the transfer of the lens, it also has labor-consuming and time-consuming problems, and cannot effectively control the blown-off position of the lens, resulting in the situation that the blown-off lens cannot be carried on the normal position of the carrier; This will increase the defect rate for subsequent lens packaging operations or inspection operations; and currently, manual use of clips is used to correct the shifted lens to an appropriate position

Embodiment Construction

[0038] See first figure 1 Shown is the flowchart of the first embodiment of the present invention, the transfer method of the contact lens lens of the present invention includes the following implementation steps: (a) make the carrier 10 loaded with the contact lens lens a and another empty carrier 20 is placed in static point position; (b) with a vacuum suction nozzle 30 suction lens a in the carrier 10 and moves to the empty carrier 20 top (as figure 2 shown); (c) use a fluid nozzle 40 to inject fluid toward the adsorption surface or edge of the lens a, so that the lens a is separated from the surface of the vacuum nozzle 30 by the fluid, and the dropped one is transferred to the empty carrier Tool 20 (such as image 3 shown). In this way, the transferred lenses can be further inspected on the carrier (d), and then transferred to another empty carrier for sealing and packaging (e); or directly together with the carrier for sealing and packaging (e )Operation.

Abstract

The invention relates to a method for shifting contact lenses, comprising the following steps: (a) a carrier loaded with the contact lenses and an empty carrier are placed into fixed point positions; (b) the lenses in the carrier are absorbed by a vacuum nozzle and shifted on the empty carrier; (c) fluid is injected towards the absorbing surfaces or edges of the lenses by a fluid nozzle to enable the lenses to be separated from the surface of the vacuum nozzle by the fluid and shifted to the empty carrier in a falling mode. The invention has the effects of high shifting efficiency and accurate actions, can save the time and the cost required by manpower and manufacture procedures and can improve the shifting yield of the lenses.

Description

technical field [0001] The present invention relates to a method for transferring contact lens lenses, in particular to a method for transferring a fixed lens from one carrier to another carrier in the contact lens manufacturing process, so as to facilitate subsequent sealing and packing of the lenses or Manufacturing technology for inspection operations. Background technique [0002] In the production technology of contact lenses, the known methods can be roughly divided into two production methods: spin mode and press mode. The former is to place glue drops in the arc-shaped cavity of a mold, and then use a rotating mechanism to rotate the mold And with the irradiation of UV lamp, the glue is made to form a lens along the surface of the cavity of the mold; the latter is to drop the glue in the arc-shaped cavity of a master mold, and then use a male mold to die-cast, to make the glue A lens is formed along the cavity surface of the master mold. Some of the lenses made by ...
