Description

Technical Field

[0001] This invention belongs to the field of optical lens manufacturing, and in particular relates to a multi-station lens inspection device for optical lens manufacturing. Background Technology

[0002] With the widespread application of optical lenses in consumer electronics, security monitoring, medical equipment, and other fields, the quality requirements for optical lenses are becoming increasingly stringent. To ensure the quality of the final product, optical lens inspection has become an indispensable part of the production process. However, traditional optical lens inspection methods have significant shortcomings in terms of automation and efficiency, especially in the loading and unloading stages, where excessive manual intervention leads to low production efficiency and increased human error rates.

[0003] Current optical lens inspection methods primarily rely on manual operation for loading and unloading. Operators manually place the lenses to be inspected onto the inspection equipment and remove the inspected products after inspection. This method is not only time-consuming and labor-intensive, but also prone to bottlenecks in the production process due to the significant amount of manual intervention. Furthermore, manual operation can introduce errors, affecting the accuracy and consistency of inspection results, thereby reducing product quality. These factors combined limit the overall efficiency and production capacity of the production line.

[0004] Therefore, there is an urgent need to develop a multi-station lens inspection device that can automatically perform loading and unloading of optical lenses. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a multi-station lens inspection device for the production of optical lenses that can automatically perform loading and unloading.

[0006] The technical solution is: a multi-station lens inspection equipment for optical lens production, including a support frame, a worktable, an electric turntable, a feeding mechanism, and an upper inspection mechanism. The worktable is fixedly connected to the top of the support frame. An electric turntable is installed on the top of the worktable, and four feeding mechanisms are mounted on the turntable. The upper inspection mechanism is installed above the feeding mechanisms on the front and rear sides. The feeding mechanism includes a fixed plate, and electric tracks are mounted on the electric turntables on both sides of the fixed plate. The sliders of the electric tracks are connected to the fixed plate. The outer surface of the fixed plate is concentrically rotatably equipped with... The rotating disk and the fixed disk have at least two shafts evenly spaced on the top. Each shaft is rotatably connected to a rotating rod, and the inner end of each rotating rod is connected to a clamping rod. The outer surface of the rotating disk has the same number of slotted holes as the shafts. A connecting block is set on the fixed disk at each slotted hole. A first spring connects the connecting block and the rotating disk. A stop block is fixedly connected to the outer surface of the rotating disk below the rotating rod. A stop bar is vertically set on the top of the worktable below the stop block. A push shaft is set on the top of the rotating disk outside the shaft. A slot is opened on the outside of each rotating rod, and the push shaft passes vertically through the slot.

[0007] Furthermore, the clamp is shaped like an inverted nail.

[0008] Furthermore, the upper detection mechanism includes a connecting frame for mounting the upper detection head, and an upper detection head mounted on the end of the connecting frame.

[0009] Furthermore, it also includes a side inspection mechanism. The side inspection mechanism is provided on the inner side of the support frame. The side inspection mechanism includes a linear module installed on the inner side of the front and rear support frames, a mounting base connected to the slider of the linear module, and a side inspection head fixed on the top of the mounting base.

[0010] Furthermore, it also includes a discharge mechanism. A discharge mechanism is provided below the discharge mechanism on both the left and right sides. The discharge mechanism includes a receiving cylinder. A receiving plate is slidably connected inside the receiving cylinder. A second spring is connected between the receiving plate and the receiving cylinder. A pusher cylinder is fixedly connected to the support frame inside the receiving cylinder through a transfer plate. A pusher plate is connected to the output end of the pusher cylinder.

[0011] Furthermore, the inner and outer surfaces of the pusher plate and the inner and outer surfaces of the receiving cylinder are on the same arc-shaped plane.

[0012] Furthermore, it also includes a storage mechanism. A storage mechanism is provided above the feeding mechanism on both the left and right sides. The storage mechanism includes connecting plates symmetrically arranged on the left and right sides of the workbench, a storage frame installed on the top of the connecting plate, a limiting ring slidably arranged in the storage frame, a third spring connecting the limiting ring and the storage frame, and a connecting rod connecting the limiting ring and the receiving plate.

[0013] Furthermore, it also includes a bottom detection mechanism installed below the front and rear feeding mechanisms. The bottom detection mechanism includes a light installed on the support frame below the feeding mechanism and a lower detection head installed on the side of the light. The angle of the lower detection head can be adjusted.

[0014] The beneficial effects of this invention are as follows: This invention can quickly detect materials through four workstations. When feeding and unfeeding, the feeding mechanism can be moved outward by the electric track to feed materials at the same time, and the materials can be automatically fixed, resulting in a high degree of automation. When detecting materials, the upper detection head, side detection head and lower detection head can detect materials comprehensively, improving the accuracy of the detection results.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Example: A multi-station lens inspection device for optical lens production, such as... Figures 1-4 and Figure 8As shown, the device includes a support frame 1, a worktable 2, an electric turntable 21, a feeding mechanism 3, and an upper inspection mechanism 4. The worktable 2 is bolted to the top of the support frame 1. The worktable 2 is hollow in the middle. An electric turntable 21 is installed on the top of the worktable 2. Four feeding mechanisms 3 are installed on the electric turntable 21. The front and rear sides are inspection stations, and the left and right sides are loading and unloading stations. An upper inspection mechanism 4 is installed above the inspection stations. The electric turntable 21 drives the four feeding mechanisms 3 to rotate, thereby changing the working position of the feeding mechanisms 3.

[0027] like Figure 3 and Figure 4 As shown, the feeding mechanism 3 includes a fixed disk 301. Electric tracks are mounted on the electric turntables 21 on both sides of the fixed disk 301. The sliders of the electric tracks are connected to the fixed disk 301, allowing the fixed disk 301 to move inward and outward via the electric tracks. A rotating disk 302 is concentrically mounted on the outer surface of the fixed disk 301. At least two shafts 303 are evenly spaced on the top of the fixed disk 301. Rotating rods 304 are rotatably connected to each shaft 303, and clamping rods 305 are connected to the inner ends of each rotating rod 304. The clamping rods 305 are inverted nail-shaped. The outer surface of the rotating disk 302 has the same number of slotted holes 306 as the shafts 303. Connecting blocks are mounted on the fixed disk 301 at the slotted holes 306. 307. A first spring 308 is connected between the connecting block 307 and the rotating disk 302. A stop block 309 is fixedly connected to the outer surface of the rotating disk 302 below the rotating rod 304 by bolts. A stop bar 3010 is vertically set on the top of the worktable 2 below the stop block 309. When the fixed disk 301 and its components move outward, the stop block 309 will contact the stop bar 3010. A push shaft 3011 is set on the top of the rotating disk 302 outside the shaft 303. A slot 3012 is opened on the outside of the rotating rod 304. The push shaft 3011 passes vertically through the slot 3012. When the rotating disk 302 rotates, the shaft 303 can drive the clamping rod 305 to swing, so that the inside of the clamping rod 305 separates or closes.

[0028] like Figure 8 As shown, the upper detection mechanism 4 includes a connecting frame 401 for mounting the upper detection head 402, and an upper detection head 402 mounted on the end of the connecting frame 401. The connecting frame 401 is concave and extends through the middle of the worktable 2 to above the feeding mechanism 3. The upper detection head 402 is fixedly connected to the upper end of the connecting frame 401 and is above the feeding mechanism 3. The irradiation surface of the upper detection head 402 is installed downwards to detect the top of the material.

[0029] like Figure 8 and Figure 9As shown, it also includes a side detection mechanism 5. The side detection mechanism 5 is provided on the inner side of the support frame 1. The side detection mechanism 5 includes a linear module 501 installed on the inner side of the front and rear support frames 1. The linear module 501 consists of a servo motor and a lead screw. The lead screw is connected to the output shaft of the motor. A mounting seat 502 is connected to the slider of the linear module 501, and a side detection head 503 is fixed on the top of the mounting seat 502. The linear module 501 can drive the side detection heads 503 to move away from each other or to move together.

[0030] like Figure 5 and Figure 6 As shown, it also includes a discharge mechanism 6. The discharge mechanism 6 is provided below the discharge mechanism 3 on both the left and right sides. The discharge mechanism 6 includes a receiving cylinder 601. A receiving plate 602 is slidably connected inside the receiving cylinder 601. A second spring 603 is connected between the receiving plate 602 and the receiving cylinder 601. A pusher cylinder 604 is fixedly connected to the support frame 1 inside the receiving cylinder 601 through a transition plate. The output end of the pusher cylinder 604 faces the receiving cylinder 601. The output end of the pusher cylinder 604 is connected to a pusher plate 605. By controlling the extension and retraction of the pusher cylinder 604, the pusher plate 605 can be driven to push away the falling material.

[0031] like Figure 6 As shown, it also includes a storage mechanism 7. The storage mechanism 7 is provided above the material feeding mechanism 3 on both the left and right sides. The storage mechanism 7 includes a connecting plate 701 symmetrically arranged on the left and right sides of the workbench 2, a storage frame 702 installed on the top of the connecting plate 701, a limiting ring 703 slidably arranged in the storage frame 702, a third spring 704 connected between the limiting ring 703 and the storage frame 702, and a connecting rod 705 connected between the limiting ring 703 and the receiving plate 602.

[0032] like Figure 8 As shown, it also includes a bottom detection mechanism 8 installed below the front and rear feeding mechanisms 3. The bottom detection mechanism 8 includes a lighting lamp 801 installed on the support frame 1 below the feeding mechanism 3, and a lower detection head 802 installed on the side of the lighting lamp 801. The angle of the lower detection head 802 can be adjusted.

[0033] In use: First, adjust the installation angle of the lower detection head 802. Then, place the camera to be detected in the storage mechanism 7. Next, control the electric turntable 21 to drive the feeding mechanism 3 to rotate. When the feeding mechanism 3 rotates to the notch of the worktable 2, the electric turntable 21 stops rotating. Then, the feeding mechanisms 3 on the left and right sides move to the bottom of the storage mechanism 7. At this time, the feeding mechanism 3 opens, and the camera in the storage mechanism 7 falls into the feeding mechanism 3. Then, the feeding mechanism 3 resets. Then, control the electric turntable 21 to rotate 90° again. At this time, the feeding mechanism 3 containing the material moves to the bottom of the upper detection mechanism 4. The upper detection mechanism 4, the side detection mechanism 5, and the bottom detection mechanism 8 detect the material. At this time, the feeding mechanisms 3 on the left and right sides feed the material. After the material on the front and back sides is detected, control the electric turntable 21 to rotate 90° again. The next material to be detected rotates to the detection position for detection. After the material is detected, it is fed on the left and right sides. At the same time, after the material is fed, the storage mechanism 7 feeds it. This process is repeated until all the materials are detected.

[0034] When feeding and unloading materials, the electric track drives the fixed plates 301 and their devices on both sides to move outward. When the stop block 309 moves outward and contacts the stop lever 3010, the stop lever 3010 drives the rotating plate 302 to rotate clockwise. At this time, the push shaft 3011 and the slot 3012 drive the rotating rod 304 to swing clockwise. At this time, the internal parts of the rotating rod 304 separate, and the material on the clamping rod 305 falls due to the separation of the clamping rod 305. The material falls onto the receiving plate 602. Due to the weight of the material, the receiving plate 602 moves downward, and the second spring 603 is compressed. When the receiving plate 602 moves downward, the connecting rod 705 drives the limiting ring 703 to move downward. At this time, the material on the limiting ring 703 moves downward and enters the clamping rod 305. Between these steps, the electric track drives the feeding mechanism 3 to move inward and reset. At this time, the stop block 309 and the stop rod 3010 disengage, the first spring 308 resets, and drives the rotating disk 302 to reset, causing the clamping rod 305 to reset. The bottom of the clamping rod 305 is below the material. At the same time, when the clamping rod 305 moves inward, it pushes the material above it to move inward and fall onto the clamping rod 305. Then, the pushing cylinder 604 is controlled to extend, driving the pushing plate 605 to move outward. The pushing plate 605 pushes the tested material out of the receiving cylinder 601. Then, the pushing cylinder 604 is controlled to drive the pushing plate 605 to reset. At this time, the second spring 603 and the third spring 704 reset, driving the receiving plate 602 and the limiting ring 703 to reset. Then, the material is replaced for the next round of testing.

[0035] When the material moves to the detection position, the upper detection head 402, the side detection head 503, and the lower detection head 802 are first connected to the display. Then, the upper detection head 402, the side detection head 503, and the lower detection head 802 are controlled to start working and begin detecting the material. The detected image is transmitted to the display, and the lighting 801 is controlled to work to ensure that the lower detection head 802 can clearly detect the bottom of the material. After the material detection is completed, the upper detection head 402, the side detection head 503, and the lower detection head 802 are controlled to stop working.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
