Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, specifically to a gripping device for an optical lens turntable. Background Technology

[0002] Optical lenses, also known as mirror cores, are the mounted painting cores suitable for being placed inside a frame, hence the name mirror core. They can be horizontal or vertical and are a simple and convenient mounting method. Optical lenses can be divided into the following four types according to different materials: resin lenses, special lenses, space lenses, and glass lenses.

[0003] According to CN116198986A, an optical lens gripping mechanism is disclosed. This technology discloses "an optical lens gripping mechanism, including a fixed base, a rotating component, a sliding component, a lifting component, and a gripping component, wherein the gripping component is located on the side away from the rotating component". It has the following technical effects: "The rotation of a motor drives the rotating rod to rotate, thereby enabling the gripping component to grip the optical lens in any direction. The sliding electric cylinder slides in the slide groove to adjust the distance between the gripping component and the optical lens, which facilitates the gripping of the optical lens. The rotation of a second motor drives the threaded rod to rotate, thereby controlling the lifting base to rise and fall on the threaded rod, thereby arbitrarily controlling the height of the gripping component, which is very convenient to adjust. After the position of the gripping component is adjusted, the electric push rod is controlled to push or retract, thereby driving the sliding sleeve to slide outside the sliding column. The gripping plate is opened and closed by the drive rod to realize the placement and gripping of the optical lens".

[0004] During batch processing, due to the varying diameters of different lenses, the fixed-spacing gripping mechanism cannot adaptively adjust its clamping position, causing the grippers to fail to accurately align with the center of the lens, resulting in a gripping position offset. This offset not only affects the accuracy of subsequent processing but may also cause damage to the lens surface due to uneven force. This problem is particularly prominent when processing high-precision optical lenses, severely restricting the flexibility of the production line and the processing quality. Utility Model Content

[0025] The transfer assembly 21 is mounted on the stand 1 and is used for transferring optical lenses;

[0026] The adjustment assembly 22 includes a mounting plate 221 disposed on the transfer assembly 21. A base plate 222 is fixed to the lower end of the mounting plate 221. A guide plate 223 is longitudinally slidably mounted on the front end of the base plate 222. A guide groove 224 is symmetrically distributed inside the guide plate 223. A slide 225 is laterally slidably mounted on the front end of the base plate 222. A guide wheel 226 is rotatably mounted on the front end of the slide 225, and the guide wheel 226 is located inside the guide groove 224. A second cylinder 227 is mounted on the top of the mounting plate 221 and is used to drive the guide plate 223 to move.

[0027] The gripping component 23 is mounted on the adjustment component 22 and is used to grip the optical lens.

[0028] In this embodiment, the guide plate 223 is driven by the output end of the second cylinder 227. The guide plate 223 drives the gripping component 23 on the slide 225 through the guide groove 224 and the guide wheel 226. This enables the synchronous and equidistant adjustment of the spacing between each gripping component 23, so that it can be adapted to the size of the multiple lenses placed. The gripping position of the gripping component 23 can be automatically adjusted according to the lenses of different diameters to ensure that the gripping center coincides with the center of the lens.

[0029] Specifically, the gripping component 23 includes a ring seat 231 mounted on the slide 225. Three circumferentially distributed grippers 232 are pivotally connected to the outer wall of the ring seat 231. A third cylinder 233 is mounted on the top of the ring seat 231. A ring frame 234 is fixed to the output end of the third cylinder 233. Three circumferentially distributed connectors 235 are pivotally connected to the outer wall of the ring frame 234, and the other end of the connectors 235 is pivotally connected to the grippers 232.

[0030] In this embodiment, the output end of the third cylinder 233 drives the ring frame 234 to cooperate with the connector 235 to drive the chuck 232 to rotate, thereby gripping the lens; by adopting a three-claw structure, uniform force is ensured during gripping, preventing lens deformation or displacement.

[0031] Specifically, the gripping component 23 also includes an extension plate 237 fixed to the upper end of the ring seat 231, and the extension plate 237 is fixed to the lower end of the carriage 225 by bolts.

[0032] In this embodiment, the gripping component 23 can be disassembled, maintained, or replaced from the adjustment component 22.

[0033] Specifically, the gripping component 23 also includes a buffer plate 236 fixed to the inner wall of the chuck 232.

[0034] In this embodiment, the buffer plate 236 is made of flexible material to prevent the clamp 232 from directly contacting the lens and to prevent scratches or pressure damage.

[0035] Specifically, the adjustment assembly 22 also includes upper limiters 228 fixed at both ends of the mounting plate 221, and lower limiters 229 fixed at both ends of the base plate 222.

[0036] In this embodiment, the movement range of the guide plate 223 is limited by the upper limit switch 228 and the lower limit switch 229 to prevent damage to the mechanical structure due to overtravel.

[0037] Specifically, the transfer assembly 21 includes a cam divider 211 fixed to the top of the upright 1, a crossbeam 212 fixed to the output end of the cam divider 211, a mounting bracket 213 fixed to the end of the crossbeam 212, a first cylinder 214 mounted on the top of the mounting bracket 213, and a mounting plate 221 fixed to the output end of the first cylinder 214.

[0038] In this embodiment, the lens after being grasped is controlled to be transferred by the cam divider 211, and the grasping height position is controlled by the first cylinder 214.

[0039] The working principle and usage process of this utility model are as follows: First, the guide plate 223 is driven by the output end of the second cylinder 227. The guide plate 223 drives the gripping component 23 on the slide 225 through the guide groove 224 and the guide wheel 226. This enables the synchronous and equidistant adjustment of the spacing between each gripping component 23, so that it can be adapted and adjusted according to the size of the multiple lenses placed. The gripping position of the gripping component 23 can be automatically adjusted according to the lenses of different diameters to ensure that the gripping center coincides with the center of the lens.

[0040] Then, the output end of the third cylinder 233 drives the ring frame 234 to cooperate with the connector 235 to drive the chuck 232 to rotate, thereby gripping the lens; by adopting a three-jaw structure, it ensures uniform force during gripping and prevents the lens from deforming or shifting.
