Description

Technical Field

[0001] The invention relates to the technical field of lens processing equipment, in particular to a vertical lens edge grinding machine. Background Art

[0002] Current lens edgers are generally horizontal, using two horizontally extending clamps to hold the lens and an edging device to edge the lens. However, when the lens is clamped by the two clamps, there is no support underneath, so the lens tends to move downward under the action of gravity. For large and heavy lenses, the lens is prone to downward displacement during the clamping process, causing the lens clamping position to change, which in turn causes the lens edging area to change, resulting in the lens edge not meeting the requirements. Therefore, horizontal edgers are not suitable for edging large and heavy lenses. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] See also Figures 1 to 12 This embodiment provides a vertical lens edger, comprising a frame 6, an edger station 9 being provided on the frame 6, and a clamping device 4 and an edger 5 being provided on the edger station 9. The clamping device 4 comprises a first clamp 41, a second clamp 42, a first rotation drive mechanism 43, a second rotation drive mechanism 44, and a clamping drive mechanism 45. The first clamp 41 and the second clamp 42 are coaxially arranged relative to each other in a vertical direction. The first rotation drive mechanism 43 is connected to the first clamp 41 to drive the first clamp 41 to rotate. The second rotation drive mechanism 44 is connected to the second clamp 42 to drive the second clamp 42 to rotate. The clamping drive mechanism 45 is connected to the first clamp 41 to drive the first clamp 41 to move closer to or away from the second clamp 42. The edging device 5 includes a grinding disc 51 and an edging drive mechanism 52 . The edging drive mechanism 52 is connected to the grinding disc 51 to drive the grinding disc 51 to rotate. The rotation axis of the grinding disc 51 is parallel to the rotation axis of the first fixture 41 and the rotation axis of the second fixture 42 .

[0031] In this embodiment, a vertical lens edger is configured to drive a first clamp 41 toward a second clamp 42 via a clamping drive mechanism 45 to clamp the lens. The first clamp 41 is then rotated via a first rotation drive mechanism 43, and the second clamp 42 is then rotated via a second rotation drive mechanism 44, thereby rotating the lens. Simultaneously, an edger drive mechanism 52 rotates a grinding disc 51 to edge the lens. Because the first clamp 41 and the second clamp 42 are coaxially disposed relative to each other in a vertical direction, when the lens is clamped by the first clamp 41 and the second clamp 42, the second clamp 42 provides support from below the lens, effectively preventing the lens from shifting due to gravity. This makes the machine suitable for edging larger and heavier lenses.

[0032] Furthermore, the frame 6 is provided with a first guide channel 601 and a second guide channel 602, and the first guide channel 601 and the second guide channel 602 extend coaxially in the vertical direction; the first rotation drive mechanism 43 includes a first rotation drive member 431, a first rotating shaft 432, and a first shaft sleeve 433, the first shaft sleeve 433 is arranged in the first guide channel 601, and the first rotating shaft 432 is rotatably arranged in the first shaft sleeve 433, one end of the first rotating shaft 432 is connected to the first clamp 41, and the other end is connected to the first rotation drive member 431; the second rotation drive mechanism 44 includes a second rotation drive member 441, a second rotating shaft 442, and a second shaft sleeve 443, the second shaft sleeve 443 is arranged in the second guide channel 602, the second rotating shaft 442 is rotatably arranged in the second shaft sleeve 443, one end of the second rotating shaft 442 is connected to the second clamp 42, and the other end is connected to the second rotation drive member 441. The first rotary drive member 431 drives the first rotating shaft 432 to rotate relative to the first sleeve 433, thereby driving the first clamp 41 to rotate. A first rolling bearing 434 is provided between the first rotating shaft 432 and the first sleeve 433, so that when the first rotating shaft 432 rotates, the first sleeve 433 does not rotate synchronously. Similarly, the second rotary drive member 441 drives the second rotating shaft 442 to rotate relative to the second sleeve 443, thereby driving the second clamp 42 to rotate. A second rolling bearing 444 is provided between the second rotating shaft 442 and the second sleeve 443, so that when the second rotating shaft 442 rotates, the second sleeve 443 does not rotate synchronously. In addition, the first guide channel 601 and the second guide channel 602 can achieve the positioning and installation of the first sleeve 433 and the second sleeve 443, thereby achieving the positioning and installation of the first rotating shaft 432 and the second rotating shaft 442, and then achieving the positioning and installation of the first clamp 41 and the second clamp 42, thereby improving the accuracy of the fit between the first clamp 41 and the second clamp 42. Preferably, the first rotation driving member 431 and the second rotation driving member 441 are both servo motors.

[0033] Furthermore, the clamping drive mechanism 45 includes a clamping drive member 451 and a clamping drive seat 452. The clamping drive seat 452 is connected to the first rotary drive member 431 and the first shaft sleeve 433. The clamping drive member 451 is disposed above the clamping drive seat 452 and is connected to the clamping drive seat 452 to drive the clamping drive seat 452 to drive the first rotary drive mechanism 43 to move, thereby driving the first clamp 41 to move toward or away from the second clamp 42. When the clamping drive member 451 drives the clamping drive seat 452 to move downward in the vertical direction, the first rotary drive member 431 and the first shaft sleeve 433 are synchronously moved downward, thereby driving the first clamp 41 to move toward the second clamp 42 to clamp the lens. When the clamping drive member 451 drives the clamping drive seat 452 to move upward in the vertical direction, the first rotary drive member 431 and the first shaft sleeve 433 are synchronously moved upward, thereby driving the first clamp 41 to move away from the second clamp 42 to release the lens. The clamping drive seat 452 is connected to both the first rotary drive member 431 and the first shaft sleeve 433, which facilitates synchronous movement of the first rotary drive member 431 and the first shaft sleeve 433 and ensures that the relative positions of the first rotary drive member 431 and the first shaft sleeve 433 remain unchanged, thereby ensuring a stable connection between the first rotary drive member 431 and the first rotating shaft 432. Preferably, the clamping drive member 451 is a pneumatic cylinder or an oil cylinder, with its fixed end connected to the frame 6 and its telescopic end connected to the clamping drive seat 452.

[0034] Furthermore, the clamping device 4 further includes a clamping guide mechanism 46, which includes a clamping guide rail 461 and a clamping slider 462. The clamping guide rail 461 extends vertically on the frame 6, and the clamping slider 462 is connected to the clamping drive seat 452 and slidably disposed on the clamping guide rail 461. When the clamping drive member 451 drives the clamping drive seat 452 to move vertically, the clamping slider 462 connected to the clamping drive seat 452 moves along the clamping guide rail 461, providing directional guidance for the movement of the clamping drive seat 452, thereby making the movement of the clamping drive seat 452 more stable.

[0035] Furthermore, a buffer 604 is provided on the frame 6, and a buffer plate 4521 is provided on the clamping drive seat 452. When the clamping drive member 451 drives the clamping drive seat 452 to move downward in the vertical direction until the buffer plate 4521 contacts the buffer 604, the buffer 604 provides a buffering effect for the clamping drive seat 452, thereby providing a buffering effect for the first rotating drive member 431, the first rotating shaft 432, the first shaft sleeve 433, and the first clamp 41.

[0036] Furthermore, the edging device 5 also includes an edging transverse movement mechanism 53 and an edging lifting mechanism 54. The edging transverse movement mechanism 53 is connected to the edging drive mechanism 52 to drive the edging drive mechanism 52 to move, thereby driving the grinding disc 51 to move closer to or away from the first clamp 41 and the second clamp 42. The edging lifting mechanism 54 is connected to the edging transverse movement mechanism 53 to drive the edging transverse movement mechanism 53 to drive the edging drive mechanism 52 to move, thereby driving the grinding disc 51 to move up and down. The edging transverse movement mechanism 53 can effectively adjust the distance between the grinding disc 51 and the first clamp 41 and the second clamp 42 to accommodate edging of lenses of different sizes. The edging lifting mechanism 54 can effectively adjust the relative height of the grinding disc 51 and the first clamp 41 and the second clamp 42 to accommodate edging of lenses of different thicknesses.

[0037] Furthermore, the edge grinding lifting mechanism 54 includes an edge grinding lifting drive 541, an edge grinding lifting guide rail 542, and an edge grinding lifting slide 543. The edge grinding lifting guide rail 542 extends along the vertical direction and is arranged on the frame 6. The edge grinding lifting slide 543 is slidably arranged on the edge grinding lifting guide rail 542. The edge grinding lifting drive 541 is connected to the edge grinding lifting slide 543 to drive the edge grinding lifting slide 543 to move along the edge grinding lifting guide rail 542. The edge grinding transverse movement mechanism 53 includes an edge grinding lifting drive 541. The edging transverse movement drive member 531, the edging transverse movement guide rail 532, and the edging transverse movement slide 533 are provided.

The edging transverse movement drive member 531 is connected to the edging transverse movement slide 533 to drive the edging transverse movement slide 533 to move along the edging transverse movement guide rail 532. When the edging transverse movement drive member 531 drives the edging transverse movement slide 533 to move horizontally along the edging transverse movement guide rail 532, the edging drive mechanism 52 is driven to move horizontally, thereby driving the grinding disc 51 to move closer to or away from the first clamp 41 and the second clamp 42. When the edge grinding lift drive 541 drives the edge grinding lift slide 543 to move along the edge grinding lift guide rail 542, it drives the edge grinding transverse movement mechanism 53 to move in the vertical direction, thereby driving the edge grinding drive mechanism 52 to move in the vertical direction, and further driving the grinding disc 51 to move up and down. The edge grinding lift drive 541 includes an edge grinding lift servo motor, an edge grinding lift screw connected to the output end of the edge grinding lift servo motor, and an edge grinding lift nut threadedly engaged with the edge grinding lift screw. The edge grinding lift nut is connected to the edge grinding lift slide 543.

[0038] Furthermore, a protective assembly 7 is provided on the edging station, comprising a protective body 71, a protective baffle 72, and a baffle driver 73.

Preferably, the baffle driver 73 is a pneumatic cylinder or an oil cylinder, with its fixed end connected to the frame 6 and its telescopic end connected to the protective baffle 72. When the baffle driving member 73 drives the protective baffle 72 to open the feed port 712, it is convenient for the lens to enter the edge grinding working chamber 711 and cooperate with the first clamp 41 and the second clamp 42; when the baffle driving member 73 drives the protective baffle 72 to close the feed port 712, it effectively avoids isolation from external interference.

[0039] Furthermore, the upper end surface of the protective body 71 is provided with a first through hole 713 and a second through hole 714 connected to the edge grinding working chamber 711, the grinding disc 51 passes through the first through hole 713 to enter the edge grinding working chamber 711, and the first clamp 41 passes through the second through hole 714 to enter the edge grinding working chamber 711.

[0040] Furthermore, the protective body 71 includes a first protective cover 7101 and a second protective cover 7102, which are detachably connected.

The frame 6 is provided with a water outlet 603 connected to the edge grinding chamber 711. The spray mechanism 55 can spray lubricating oil onto the grinding disc 51 and the edge of the lens to achieve a better edge grinding effect. In addition, the sprayed lubricating oil can be discharged through the water outlet 603 or collected and processed to prevent the accumulation of lubricating oil in the edge grinding chamber 711.

[0042] Furthermore, the vertical lens edge grinding machine also includes a storage bin 1, a pick-up and placement device 2 and a transfer device 3, wherein the storage bin 1 is provided with a plurality of lens trays 13; the pick-up and placement device 2 is used to move the lens tray 13 out of the storage bin 1 and / or place the lens tray 13 into the storage bin 1; the transfer device 3 is used to transfer the lens from the lens tray 13 to the edging station and / or transfer the lens from the edging station to the lens tray 13. The storage bin 1 can store multiple lens trays 13. During the loading process of the edging station 9, the lens tray 13 can be moved out of the storage bin 1 through the pick-and-place device 2, and then the lens 14 can be transferred from the lens tray 13 to the edging station 9 through the transfer device 3. When the processing is completed, the lens 14 is transferred from the edging station 9 to the lens tray 13 through the transfer device 3, and then the lens tray 13 is placed in the storage bin 1 through the pick-and-place device 2. There is no need to arrange special personnel to be stationed, which can effectively reduce labor costs, save time and effort, and has a high degree of mechanical automation.

[0043] Furthermore, the pick-and-place device 2 includes a tray bracket 21 fixedly disposed between the storage bin 1 and the edging station, a pick-and-place arm 22 movably disposed between the storage bin 1 and the edging station, and a pick-and-place driving member 23 connected to the pick-and-place arm 22 to drive the pick-and-place arm 22 to move.

After the pick-and-place driving member 23 drives the pick-and-place arm 22 to remove the lens tray 13 from the storage bin 1, the lens tray 13 can be temporarily and stably placed on the tray bracket 21 for loading and unloading.

[0044] The pick-and-place actuator 23 can be an electric cylinder, a modular product that integrates a servo motor and a lead screw. The cylinder converts the servo motor's rotational motion into linear motion. A slider, threadedly connected to the lead screw, connects to the pick-and-place arm 22. Rotation of the servo motor drives the lead screw, which in turn drives the slider, which in turn moves the pick-and-place arm 22.

[0045] Furthermore, the tray bracket 21 is provided with a tray channel 210 extending from the storage bin 1 to the edging station, the storage bin 1 includes a storage rack 11 and a lifting assembly 12, and a plurality of lens trays 13 are arranged on the storage rack 11 from top to bottom. The lifting assembly 12 is connected to the storage rack 11 to drive the storage rack 11 to rise and fall.
