Description

Technical Field

[0001] This utility model relates to the field of aspherical lens molding technology, and in particular to an aspherical lens molding equipment. Background Technology

[0002] The rise of aspherical lens molding technology stems from the bottlenecks encountered by traditional optical manufacturing processes in meeting the demands for high-efficiency and high-precision production. Before this technology matured, aspherical lenses mainly relied on skilled workers to perform manual or semi-automatic processing through multiple steps such as rough grinding, fine grinding, and polishing. The entire process was not only lengthy and costly, but also difficult to guarantee batch-to-batch stability and high product precision. These shortcomings were even more pronounced in large-scale production scenarios.

[0003] The primary concern is the shortcomings of aspherical lens molding equipment in terms of rapid pressure component replacement. These shortcomings directly impact production efficiency and stability, with the core issue being the cumbersome and time-consuming nature of traditional pressure component replacement processes. Many existing machines require multiple mechanisms and actions to coordinate during mold replacement. For example, in some designs, the bottom mold cannot be replaced directly; instead, a cylinder must first lift the bottom mold, then manually or through another mechanism insert a wedge for locking and support, before the cylinder can finally lower, securing the bottom mold to the wedge. This multi-step process not only prolongs the replacement operation itself, leading to extended equipment downtime, but also, due to its complexity, introduces errors at each step, making it difficult to guarantee the final positional accuracy and stability of the replacement.

[0004] An existing aspherical lens molding equipment features a replaceable pressure column assembly with an adjustable mechanism. This allows for the selection and replacement of pressure columns of different materials and sizes for different lens modules, enabling quick installation and fixation. The lower mechanism can also adjust the position of the lens module mechanism vertically by adjusting the worm gear assembly to determine the appropriate molding distance. A triangular block assembly is used to limit and fix the lens, making the operation safe and efficient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an aspherical lens molding equipment.

[0006] This utility model is achieved by the following technical solution: an aspherical lens molding equipment, including a frame mechanism, an adjustment mechanism and a core mechanism, wherein the adjustment mechanism is fixedly connected to the inner side of the frame mechanism and the core mechanism is fixedly connected to the upper end of the adjustment mechanism.

[0007] The frame structure includes a top plate, a hydraulic actuator fixedly connected to its lower end, an insert plate fixedly connected to the lower end of the hydraulic actuator, fixed columns fixedly connected to both sides of the hydraulic actuator, an auxiliary insert plate fixedly connected to the lower end of the insert plate, and a bottom plate fixedly connected to the lower end of the fixed column.

[0008] The above technical solution, with its replaceable pressure column assembly and adjustable mechanism, allows for the selection and replacement of pressure columns of different materials and sizes for different lens modules, enabling quick installation and fixation. The lower mechanism can also adjust the position of the lens module mechanism up and down by adjusting the worm gear assembly to determine the appropriate molding distance. The triangular block assembly is used to limit and fix the lens, making the operation safe and efficient.

[0009] As a further improvement to the above solution, the adjustment mechanism includes a servo motor, a rotating shaft fixedly connected to the inner side of the servo motor, a worm gear fixedly connected to the outer wall of the rotating shaft, a turbine engaged at the right end of the worm gear, a lead screw fixedly connected to the upper end of the turbine, a sliding plate threadedly connected to the outer wall of the lead screw, a fixed plate fixedly connected to the lower end of the sliding plate, and two fixed plates are provided, with the other fixed plate located at the rear end of the mechanism, and a sliding column fixedly connected to the outer wall of the other fixed plate, and a socket bracket fixedly connected to the outer end of the fixed plate.

[0010] The purpose of setting up the adjustment mechanism through the above technical solution is to break the limitation of the traditional locking of the lower lens mechanism of the molding machine, and to change the lens mechanism from a non-adjustable mode to an adjustable mode. By using the existing worm gear technology in combination with the pressure relief fixing component, the horizontal position of the lens mechanism can be adjusted, thereby adjusting the appropriate distance from the upper molding machine.

[0011] As a further improvement to the above solution, the core mechanism includes a threaded column one, a pressure column threadedly connected to the outer wall of the threaded column one, a housing fixedly connected to the outer side of the pressure column, a threaded column two rotatably connected to the inner wall of the housing, a clamping plate fixedly connected to the inner side of the threaded column two, a handle rotatably connected to the outer side of the threaded column two, a triangular block fixedly connected to the lower surface of the pressure column, a rotator threadedly connected to the inner wall of the triangular block, a pressure plate fixedly connected to the inner surface of the rotator, a lens module fixedly connected to the lower end of the pressure column, a holding groove fixedly connected to the lower end of the lens module, a protective shell fixedly connected to the outer side of the holding groove, a circular plate fixedly connected to the lower end of the protective shell, and a tension relief column fixedly connected to the lower end of the circular plate.

[0012] Through the above technical solution, the inner wall of the pressure column has internal threads, which are connected to the threaded column with external threads to achieve threaded rotation. Combined with the threaded column two-turn handle assembly on its outer wall, the pressure column can be double-fixed to avoid the pressure column shaking and instability during molding.

[0013] As a further improvement to the above solution, an elliptical opening groove is provided on the lower surface of the pressure column to compress the lens module for molding.

[0014] The elliptical opening groove, as described above, is designed to meet the original intention of this device and must conform to the shape and size of aspherical lenses currently on the market.

[0015] As a further improvement to the above solution, the number of fixing plates and socket brackets are both set in two groups, one group is distributed on the outside of the worm gear mechanism, and the other group is distributed on the outside of the sliding column.

[0016] With the above technical solution, two sets of fixing plates and socket brackets are set at the front and rear ends of the device to link the adjustment device of the adjustment mechanism and lock it for the specific plane where the real-time adjustment is located.

[0017] As a further improvement to the above solution, the tension relief column can be stretched up and down and fixed with the adjustment mechanism, which is set to improve stability and relieve pressure.

[0018] Through the above technical solution, the tension relief column can be stretched or compressed according to the specific position adjusted by the upper lens module, and the pressure is relieved for the entire mechanism during operation to ensure the stability and rigor of the system.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a replaceable pressure column assembly. For lens modules of different sizes and requirements, pressure columns of different materials and sizes need to be replaced. Traditional molding machines cannot easily replace their core compression components, which would require large-scale disassembly, greatly increasing the difficulty of the work and wasting time. To address this drawback, a suitable pressure column can be threaded onto the outside of the threaded column, and pressure can be applied to the clamping plate through the throttle assembly, thereby achieving the effect of double-fixed pressure columns.

[0021] This utility model, by setting an adjustable mechanism with a tension relief column, can respond and adjust in real time to different working needs. It starts a servo motor to drive the worm gear to rotate, adjusts the upper and lower positions of the slide plate assembly on the outer wall of the lead screw, and fixes it with a suitable socket in the socket frame by selecting a fixing plate. The tension relief column at the lower end stretches or compresses according to the real-time situation, and relieves pressure and stabilizes the upper mechanism. Attached Figure Description
