Description

Technical Field

[0001] This utility model relates to the field of optical lens manufacturing equipment, specifically to a lens suction cup hand device. Background Technology

[0002] Lens suction cup hand-held devices are generally controlled by a robotic arm. After the lens is formed in the injection molding machine, the robotic arm drives the suction cup hand-held device to pick up the lens and sprue column through the suction nozzle, and bring them to the cutting machine fixture for automatic laser shearing. After the lens is cut and separated, it is picked up by the suction nozzle. However, when picking up very small refractive lenses, especially when the lens diameter is less than 1 cm, the diameter of the suction nozzle also needs to be reduced accordingly. If the diameter of the suction nozzle is too small, the negative pressure inside the nozzle cannot be converted to normal pressure quickly, or even at all, often resulting in problems with proper desorption and ejection, thus affecting production efficiency. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a lens suction cup hand device to reduce abnormal situations during lens throwing and improve production efficiency.

[0004] A lens suction cup hand device includes a robotic hand, suction cups, a sliding plate, and a driving mechanism. The robotic hand and the sliding plate are arranged parallel to each other. The driving mechanism connects the robotic hand and the sliding plate and can drive the sliding plate to slide in a direction close to or away from the robotic hand. Several suction cups are disposed at one end of the robotic hand near the sliding plate. Each suction cup includes several suction nozzles. The sliding plate has several first through holes, each corresponding to a suction nozzle. The sliding plate can pass through the suction nozzles when sliding. The diameter of the first through holes is smaller than the outer diameter of the lens.

[0005] The lens suction cup hand device described in this utility model uses a suction cup on a mechanical hand to pick up the cut lens. When it is transferred to the collection point, the drive mechanism drives the slide plate, which slides vertically and contacts the lens, pushing the lens to detach from the suction nozzle, thus completing the material throwing.

[0006] As a preferred embodiment, the device also includes a robotic arm connected to the robotic hand for driving the movement of the robotic hand.

[0007] As a preferred embodiment, the skateboard is located below the mechanical hand.

[0008] As a preferred embodiment, each suction cup is provided with 12 suction nozzles arranged in a circular pattern.

[0009] As a preferred embodiment, the robotic arm also includes a glue inlet, and each suction cup is further provided with an injection port, with the glue inlet and the injection port communicating with each other. By providing the glue inlet and the injection port, the device can also be used in the injection molding process, improving the continuity of the production process and increasing production efficiency.

[0010] As a preferred embodiment, the injection port is located on the upper surface of the robotic hand, and the slide plate is also provided with a plurality of second through holes, each of which corresponds to one of the injection holes.

[0011] As a preferred embodiment, the drive mechanism includes a cylinder, with its two ends connected to the robotic hand and the sliding plate, respectively. The cylinder controls the sliding of the sliding plate relative to the robotic hand.

[0012] As a preferred embodiment, there are four cylinders, located around the mechanical hand and the slide plate, respectively.

[0013] As a preferred embodiment, the device also includes a pneumatic component connected to the nozzle via an air passage for controlling the adsorption and desorption of the nozzle.

[0014] As a preferred embodiment, the diameter of the lens is less than 1 cm. Attached Figure Description

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] like Figure 1-4 As shown, the lens suction cup hand device of this utility model includes a mechanical hand 1, a sliding plate 2, a drive mechanism 3, a suction cup 4, a pneumatic component 5, and a mechanical arm 6. The mechanical hand 1 and the sliding plate 2 are arranged parallel to each other, with the sliding plate 2 located below the mechanical hand 1 and connected to the mechanical hand 1 via the drive mechanism 3. The drive mechanism 3 drives the sliding plate 2 to slide vertically. There are four drive mechanisms 3, located around the mechanical hand 1 and the sliding plate 2 respectively. In this embodiment, the drive mechanism 4 is a cylinder. The mechanical arm 6 is located above the mechanical hand 1 and connected to the center point of the mechanical hand 1.

[0025] The robotic hand 1 has several glue inlets 11. Suction cups 4 are located below the robotic hand 1. Each suction cup 4 has 12 suction nozzles 41 and 3 injection ports 42, with the 12 suction nozzles 41 arranged in a circle and the 3 injection ports 42 located within the circle formed by the 12 suction nozzles 41. The sliding plate 2 has several first through holes and several second through holes. The diameter of the first through holes is larger than the outer diameter of the suction nozzles 41 but smaller than the outer diameter of the lens 7, corresponding one-to-one with the suction nozzles 41. The sliding plate 2 can pass through the suction nozzles 41 when sliding vertically. The second through holes correspond one-to-one with the injection ports 42. The glue inlets 11 are located above the robotic hand 1 and are connected to the injection ports 42. The pneumatic assembly 5 is connected to the suction nozzles 41 via an air path and is used to control the adsorption and detachment of the lens 6 on the suction nozzles 41.

[0026] The working principle of this lens suction cup palm device is as follows:

[0027] A sprue column is pre-placed inside the injection molding machine. The robotic arm 6 moves the robotic hand 1 above the sprue column inside the injection molding machine. At this time, the robotic hand 1 is aligned with the sprue column. Raw material is introduced through the sprue inlet 14 and injected into the sprue column through the injection port 13. After the lens 7 inside the sprue column is formed, the pneumatic component 5 controls the suction nozzle 12 to pick up the sprue column. The robotic arm 6 then moves the robotic hand 1 into the cutting machine. After the cutting machine finishes cutting, the pneumatic component 5 controls the suction nozzle 41 to pick up the lens 7. The robotic arm 6 then takes the robotic hand 1 out of the cutting machine. At this time, the drive mechanism 3 drives the slide plate 2 to slide vertically. When the slide plate 2 slides, the first through hole passes through the suction nozzle 41 and contacts the lens 7, so that the lens 7 completes the ejection.

[0028] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
