Description

Technical Field

[0001] This utility model relates to the field of optical lens testing technology, specifically to an automatic feeding mechanism for optical lens testing. Background Technology

[0002] Optical lenses are generally made of optical glass, which is a mixture of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula. The mixture is melted at high temperature in a crucible, stirred evenly with ultrasound to remove air bubbles, and then slowly cooled for a long time to prevent internal stress from forming in the optical glass. After cooling, the optical glass must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications.

[0003] According to the patent titled "An Automatic Feeding Mechanism for Optical Lens Inspection" (Patent Publication No.: CN220431562U, Patent Publication Date: 2024-02-02), the mechanism includes a worktable, a feeding mechanism on the top of the worktable, and a transfer component on one side of the worktable, relating to the field of optical lens inspection technology. This automatic feeding mechanism for optical lens inspection, through its feeding mechanism, allows a single lens to slide along a material rail into the loading table via a feeding component. Then, driven by a drive cylinder, a push plate pushes the lens to the top of the loading table. The transfer component uses a suction cup to pick up the lens from the push plate and transfer it to the optical lens inspection equipment. During the process of the drive cylinder resetting the push plate, a top block component drives a rotating roller to rotate. The rotating roller, through a transmission component, drives the feeding component, allowing the next lens to enter the loading table. The linkage between the components ensures that lenses are continuously and orderly fed into the optical lens inspection equipment, solving the problem of lens damage during manual operation.

[0004] Based on the aforementioned existing technology, the current automatic loading mechanism for optical lens inspection still has the following problems: the existing optical lens inspection requires workers to manually load the lenses onto the inspection table. This process is not only inefficient, but the uncontrollability of worker operation also increases the risk of damage to delicate and fragile lenses. Therefore, this utility model provides an automatic loading mechanism for optical lens inspection. Summary of the Invention

[0025] The reciprocating unit 21 is located at the rear of the detection mechanism 3. It includes a frame 211, and a mounting box 212 is fixedly installed on the top of the frame 211. A set of slide rails 213 is fixedly installed on the top of the mounting box 212. A set of slide blocks 214 is slidably installed above the slide rails 213. A frame plate 215 is fixedly installed above the slide blocks 214. The two slide blocks 214 are fixedly connected by a connecting rod 217. The two slide blocks 214 clamp and move the lens through the clamping assembly 4 to realize the loading, detection and unloading operations.

[0026] The drive unit 22 is located inside the mounting box 212 and is used to drive the slide 214 to move.

[0027] The two slides 214 are rigidly connected by a connecting rod 217 and are driven to move synchronously by a cylinder 222. When the right-side gripping assembly moves the lens to the inspection stage 31 for inspection, the left-side gripping assembly can simultaneously pick up a new lens from the conveying mechanism 1 or place an inspected lens into the collection box 34, eliminating the idle waiting time of a traditional single robotic arm, improving work efficiency, and avoiding the uncontrollability of manual operation.

[0028] In this embodiment, the clamping assembly 4 includes a fixed frame 41 fixedly installed inside the frame plate 215. The two fixed frames 41 are connected by a fixed rod 216. A gear 42 is rotatably installed inside the front end of the fixed frame 41, and a second rack 46 and a first rack 43 are slidably installed inside the front end of the fixed frame 41. The second rack 46 and the first rack 43 are located above and below the support frame 32, respectively. A first clamping rod 45 is fixedly installed at one end of the first rack 43 through a first connecting rod 44, and a second clamping rod 48 is fixedly installed at one end of the second rack 46 through a second connecting rod 47.

[0029] In this embodiment, a motor frame 49 is fixedly installed on the inner side of the fixing frame 41, and a drive motor 410 is fixedly installed on the inner side of the motor frame 49. The output end of the drive motor 410 extends through the through hole of the motor frame 49 to one side of the second connecting rod 47 and is fixedly connected thereto.

[0030] The clamping assembly 4 adopts a symmetrical gear and rack transmission. The first rack 43 and the second rack 46 are linked together. The drive motor 410 controls the first clamping rod 45 and the second clamping rod 48 to move in opposite directions synchronously through the gear 42, so as to achieve uniform force on the lens and controllable clamping force, avoiding breakage or scratches caused by local stress. At the same time, the inclined groove design of the clamping block enables the clamping of lenses of different sizes.

[0031] In this embodiment, the drive unit 22 includes a mounting plate 221 fixedly installed inside the mounting box 212. A cylinder 222 is fixedly installed on the left side of the mounting plate 221, and a linkage plate 223 is fixedly installed at the bottom of the right slide block 214. The output end of the cylinder 222 passes through the mounting plate 221 and extends to one side of the linkage plate 223 and is fixedly connected thereto. A through groove 224 is provided on the right side of the inside of the mounting box 212, and the linkage plate 223 slides inside the through groove 224.

[0032] In this embodiment, the detection mechanism 3 includes a detection table 31, a support frame 32 is fixedly installed on the front side of the detection table 31, and a detection camera 33 is fixedly installed on one end of the support frame 32.

[0034] In this embodiment, a collection box 34 is fixedly installed on the left side of the testing station 31 for collecting the tested lenses.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, firstly, the adjustment component on the conveyor mechanism 1 adjusts the lens to pass through the space, the motor of the conveyor mechanism 1 runs, and drives the conveyor belt through two rollers. The conveyor belt transports the lens, and the lens is limited in position by the stop block at the left end of the conveyor mechanism 1.

[0037] Next, cylinder 222 operates, pushing linkage plate 223. Linkage plate 223 drives slide 214 and frame plate 215 to move synchronously. Clamping assembly 4 moves to the top of the lens above the conveying mechanism 1. Drive motor 410 runs to push second rack 46. Second rack 46 drives first rack 43 to move in the opposite direction through gear 42, causing first connecting rod 44 and second connecting rod 47 to move towards each other. First connecting rod 44 and second connecting rod 47 drive first clamping rod 45 and second clamping rod 48 to move synchronously to clamp the lens, thus achieving lens clamping.

[0038] Then, cylinder 222 pulls linkage plate 223, causing slide 214 and frame 215 to move synchronously. The right clamping component 4 moves the lens to the top of the inspection table 31, and the lens is inspected by inspection camera 33. After that, cylinder 222 pushes linkage plate 223, which causes slide 214 and frame 215 to move synchronously. The right clamping component 4 clamps the lens to be inspected on the conveying mechanism 1, and the left clamping component 4 clamps the inspected lens. Cylinder 222 pulls linkage plate 223 again, which causes slide 214 and frame 215 to move synchronously. The left clamping component 4 moves to the top of collection box 34, and the right clamping component 4 moves to the inspection area. The two clamping components 4 release their clamping on the lens, and the inspected lens enters the inside of collection box 34. The lens to be inspected is placed on the top of inspection table 31 for inspection.
