[0011] For the above-mentioned mold clamping machine, the two processes of measuring A mold and B mold and winding tape are serial. When completing the mold clamping of a mold, it is necessary to make the upper fixture and the lower fixture perform three relative movements and Two back movements, it can be seen that it takes a long time to complete one mold clamping, so the mold clamping efficiency of the existing mold clamping machine is low

Abstract
The invention discloses a mold assembly method of a lens mold. The method comprises a clamping center coordinate measuring step, a sucking step and a mold assembly step, wherein after a conveying mechanism clamps the peripheral surface of a mold A and the peripheral surface of a mold B correspondingly, a first measuring device is used for measuring coordinates of the center of the mold A, and a second measuring device is used for measuring the coordinates of the center of the mold B in the clamping center coordinate measuring step; the conveying mechanism enters the position between an upper fixing device and a lower fixing device of a mold assembly device, the upper fixing device and the lower fixing device move towards each other in opposite directions, the upper fixing device sucks themold A, the lower fixing device sucks the mold B, the upper fixing device which sucks the mold A and the lower fixing device which sucks the mold B move off each other in opposite directions to make space, and the conveying mechanism exits from the position between the upper fixing device and the lower fixing device, and the clamping center coordinate measuring step is repeated in the sucking step; and the upper fixing device which sucks the mold A and the lower fixing device which sucks the mold B move towards each other in opposite directions, and an adhesive tape is used for winding the circumferential surface of the mold A and the circumferential surface of the mold B so as to assemble the mold A and the mold B in the mold assembly step. The method has the advantage of short mold assembly time.
Description
technical field [0001] The invention relates to the technical field of lens mold clamping, in particular to a lens mold clamping method, a detection device and a mold clamping machine. Background technique [0002] In the production process of resin lenses, the lens molds are first cleaned, and then the two lens molds that have passed the cleaning are combined, and then the monomers used to form the lenses are loaded, that is: the resin is pre-polymerized according to a certain formula to reach a certain viscosity, and then subjected to vacuum After degassing, the monomer used to form the lens is injected into the assembled lens mold cavity, and the filled mold is placed in an oven. After a thermal cycle, the monomer used to form the lens is cured, and then passed through Open the mold to produce semi-finished lenses, and the semi-finished lenses are processed into finished lenses after subsequent processing. [0003] The lens mold is made up of A mold A1 and B mold B1, and...
