Description

Technical Field

[0001] The utility model relates to the technical field of lens material taking mechanisms, in particular to a taking and placing mechanism for non-spherical mold lenses and mold rings. Background Art

[0002] The compression molding equipment is a mechanism that first puts some granules into the lower mold A at the molding temperature, and then closes the mold and presses it to form and solidify it. During the processing and molding of lens B, some lenses are provided with a positioning edge for connecting with the lens barrel. When molding the positioning edge of lens B, a mold ring C with a shape is required; the molding machine presses the material and the mold ring C in the lower mold A to form lens B.

[0003] However, since the mold ring C is stuck on the positioning edge of the lens B, the mold ring C also needs to be removed when the lens is removed. In the existing compression molding equipment, the suction pen structure only has the function of adsorbing the lens. When the lens is sucked out, the mold ring is taken out together and placed in the material tray. Then, before the next compression molding, the mold ring C is put back into the lower mold A by the robot. This pick-and-place structure requires two robots to cooperate with each other, and the pick-and-place structure is complicated and requires a large layout space. Utility Model Content

[0004] The utility model aims to provide a mechanism for taking and placing aspherical mold lenses and mold rings in view of the defects and shortcomings of the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model discloses a mechanism for taking and placing aspheric mold lenses and mold rings, which comprises a column and a lifting assembly connected to the column; the lifting assembly is connected to a suction pen fixing seat; the suction pen fixing seat is fixed with a suction pen;

[0007] A middle suction hole is arranged in the middle of the suction pen; an annular groove is arranged on the bottom end surface of the suction pen; the annular groove is arranged outside the middle suction hole; a second vacuum joint is connected to the annular groove; and a first vacuum joint is connected to the middle suction hole.

[0008] Furthermore, a first connecting hole connected to the annular groove is provided on the outer wall of the suction pen; a connecting seat is fixed on the suction pen fixing seat; the suction pen is fixed on the connecting seat; a second connecting hole connected to the first connecting hole is provided on the connecting seat; and the second vacuum joint is connected to the annular groove through the second connecting hole.

[0009] Furthermore, the lifting assembly includes a first lifting rail fixed on the column, a first lifting slider slidably connected to the first lifting rail, a lifting seat fixed on the first lifting slider, and a lifting cylinder connected between the column and the lifting seat; the suction pen fixing seat is fixed on the lifting seat.

[0010] Furthermore, a second lifting guide rail is fixed on the lifting seat; a second sliding block is slidably connected to the second lifting guide rail; a sliding seat is fixed on the second sliding block; the suction pen fixing seat is fixed on the sliding seat; and a buffer cylinder is connected between the lifting seat and the sliding seat.

[0011] After adopting the above structure, the beneficial effects of the utility model are as follows: the utility model describes a pick-and-place mechanism for a non-spherical mold lens and a mold ring. In this structure, after the lens is molded, the upper mold head of the molding machine withdraws from the lower mold; the manipulator connected to the pick-and-place mechanism moves the pick-and-place mechanism to the top of the lower mold; then the lifting component drives the suction pen to extend into the inner cavity of the lower mold and the end face of the suction pen with an annular groove hole fits on the end face of the mold ring, so that the concave cavity on the top surface of the lens and the mold ring form a cavity connected to the middle suction hole, so that the middle suction hole can take the lens and the mold ring. The ring is sucked up together; in this state, the annular groove can serve as an auxiliary adsorption to suck up the mold ring; when the lens is placed in the tray and positioned, the middle suction hole is shut off, but the negative pressure continuously generated by the annular groove adsorbs and fixes the mold ring, and the lens falls into the tray due to gravity, and the mold ring is put back into the lower mold together with the pick-and-place mechanism to form the next lens; the pick-and-place mechanism of this structure is integrated on the suction pen of the same pick-and-place mechanism, which simplifies the structure of the pick-and-place mechanism and can make the volume of the pick-and-place mechanism more compact and easier to layout in space.
