Description

Technical Field

[0001] The utility model relates to the technical field of lens disassembly, and in particular to an automatic lens disassembly and sorting device. Background Art

[0002] With the development of the domestic optical industry, the demand for optical lenses is also increasing. In the modern lens production and assembly process, after all lens components are assembled, some unqualified finished lenses are inspected and cut with a lens cutting machine. In order to recycle the useful parts inside the lens, reuse them, and reduce production costs. This requires that after the lens is cut, the useful parts inside must be disassembled and sorted out to recycle the useful parts.

[0003] Since manual disassembly and sorting with tools involve a large number of human factors, it all depends on the experience and skills of the disassembler and sorter. It is difficult to maintain the accuracy of the disassembly position and avoid excessive force to damage useful parts like a machine. At the same time, in the process of manual disassembly of useful parts in the lens, it is necessary to operate by hand, which can easily cause fingerprints to stick to the parts, contaminating the product and affecting later recycling and use.

[0007] The lifting and clamping double-station assembly includes a chuck for clamping the lens to be disassembled, a screw motor for ejecting the parts to be sorted inside the lens upward from the bottom of the chuck, a parts pre-pressing plate for pre-pressing the product to prevent it from scattering and tilting, and a pre-pressing mechanism switching shaft for adjusting the position of the pre-pressing mechanism. The top surface of the free end of the parts pre-pressing plate is provided with an inverted U-shaped bracket plate, the inner wall of the U-shaped bracket plate is connected to a vacuum suction cup tail seat through a lifting component, and the bottom surface of the vacuum suction cup tail seat is connected to a vacuum suction cup component through a pipe longitudinally penetrating the parts pre-pressing plate, and the vacuum suction cup component absorbs the parts inside the lens in the product.

[0008] Preferably, the lifting component includes electric push-pull rods symmetrically fixedly mounted on the inner top wall of the U-shaped bracket plate, and the bottom push-pull ends of the two electric push-pull rods are fixedly connected to the top surface of the vacuum suction cup tailstock.

[0009] Preferably, the sorting device further comprises a Y-axis duplex station for clamping and transporting, and the Y-axis duplex station for clamping and transporting comprises a moving module and a slidingly connected parts recovery clamping head.

[0010] Preferably, the movable module moves in the Y-axis direction and removes the ejected parts from the lifting and clamping station through the parts recovery chuck.

[0011] Preferably, the sorting device further comprises a parts recovery gripper X-axis and a parts classification recovery material box;

[0012] The parts recovery clamping jaw X-axis cooperates with the clamping and transporting Y-axis double station to receive the parts transferred from the parts recovery clamping head and transport them to the designated recovery position.

[0013] Preferably, the parts classification and recycling box is provided with a plurality of corresponding recycling slots for receiving and storing the sorted parts delivered by the parts recycling gripper X-axis.

[0014] In this solution, the component recovery chuck includes a slider support slidably connected to the moving module, a support plate fixedly installed on the top surface of the slider support, and a drive motor installed on the edge side of the top surface of the support plate;

[0015] And a clamping insert plate which is slidably mounted on the top surface of the supporting plate and driven by a driving motor to move linearly.

[0016] Preferably, a clamping movable plate is symmetrically mounted on the top surface of the support plate and on one end facing away from the drive motor, and the free ends of the two clamping movable plates are connected with clamping claws for clamping the product;

[0017] The two clamping movable plates are relatively slidably mounted on the slide rail member on the top surface of the supporting plate member.

[0021] The lens disassembly automatic sorting device can ensure the accurate position of the lens during the disassembly process through the precise control of the X-axis of the loading and unloading clamps and the fine design of the lifting and clamping double-station components, avoiding component damage caused by human operation errors; the application of component pre-pressing plates and vacuum suction cup systems not only prevents components from scattering and tilting during the ejection process, but also reduces direct contact and potential damage to the component surface through non-contact adsorption, ensuring the integrity of the components;

[0022] The vacuum suction cup creates negative pressure between the suction cup and the product surface by vacuuming, thus generating a strong adsorption force. This adsorption force is sufficient to overcome the friction and other obstacles of the product inside the lens, ensuring that it can be extracted quickly and firmly, avoiding the problems of jamming or slipping that may be encountered in manual operation; the vacuum suction cup does not directly contact the surface of the product during the adsorption process, but adsorbs the product by generating negative pressure through the sealed suction cup port. This method avoids the scratches, scrapes or deformations that may be caused by traditional tools, and protects the original state and quality of the product. It is especially important for optical parts that are fragile or have high surface requirements. It helps to quickly, safely and accurately remove the product from the lens, thereby improving the efficiency of lens disassembly and sorting. BRIEF DESCRIPTION OF THE DRAWINGS
