DETAILED DESCRIPTION

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0032] Example 1

[0033] An automatic feeding device for optical lens detection, such as Figure 1-Figure 3 As shown, it includes a mounting frame 1, a detector 2, a threaded rod 21, a loading mechanism 3 and a feeding mechanism 4. The upper part of the mounting frame 1 is connected to the threaded rod 21 by threads, and the bottom of the threaded rod 21 is connected to the detector 2. The detector 2 is used to detect the optical lens. The lower part of the mounting frame 1 is provided with a loading mechanism 3, which can convey the optical lens. The upper part of the mounting frame 1 is provided with a feeding mechanism 4, which can store multiple optical lenses.

[0034] When using the device, the staff puts the optical lenses that need to be inspected into the feeding mechanism 4, and drops the optical lenses one by one onto the loading mechanism 3 through the feeding mechanism 4. The loading mechanism 3 transports the optical lenses one by one to the bottom of the detector 2 for inspection. At the same time, the staff can also rotate the threaded rod 21 as needed. The threaded rod 21 will move upward or downward while rotating, thereby driving the detector 2 to move up and down to adjust the height, making it more convenient to carry out the inspection work.

[0035] like Figure 1 and Figure 2 As shown, the feeding mechanism 3 includes a conveying assembly, a mounting plate 32, a full gear shaft 33, a driving motor 34 and a missing gear shaft 35. A conveying assembly is provided at the lower part of the mounting frame 1, a mounting plate 32 is welded to the lower left part of the mounting frame 1, the upper right part of the mounting plate 32 is rotatably connected to the full gear shaft 33, the full gear shaft 33 is connected to the conveying assembly, the upper left part of the mounting plate 32 is rotatably connected to the missing gear shaft 35, the missing gear shaft 35 rotates and meshes with the full gear shaft 33, the upper part of the mounting plate 32 is bolted with a driving motor 34, and the output shaft of the driving motor 34 is connected to the missing gear shaft 35 through a coupling.

[0036] like Figure 1 and Figure 2 As shown, the conveying assembly includes a conveying frame 31, a roller 311, a conveyor belt 312 and a partition 313. The conveying frame 31 is symmetrically welded to the lower part of the mounting frame 1. The upper part of the conveying frame 31 is rotatably connected to the roller 311. The roller 311 on the left is connected to the full gear shaft 33. The conveyor belt 312 is sleeved between the left and right rollers 311, and at least four partitions 313 are evenly spaced and connected to the conveyor belt 312.

[0037] When using the device, the staff starts the drive motor 34, and the output shaft of the drive motor 34 rotates to drive the missing gear shaft 35 to rotate. When the missing gear shaft 35 rotates to engage with the full gear shaft 33, the missing gear shaft 35 rotates to drive the full gear shaft 33 to rotate. The rotation of the full gear shaft 33 drives the roller 311 on the left to rotate, and then drives the conveyor belt 312 to rotate. The conveyor belt 312 rotates to bring out the optical lenses in the feeding mechanism 4 one by one through the partition 313, thereby transporting the optical lenses to the bottom of the detector 2. When the missing gear shaft 35 rotates to disengage from the full gear shaft 33, the conveyor belt 312 stops rotating, which facilitates the detector 2 to detect the optical lens directly below. When the missing gear shaft 35 rotates again to engage with the full gear shaft 33, the conveyor belt 312 continues to rotate to transport the next optical lens to the bottom of the detector 2 for detection. When the device is used, the staff turns off the drive motor 34.

[0038] like Figure 1 and Figure 3 As shown, the feeding mechanism 4 includes a connecting rod 41, a feeding frame 42 and a partition frame 43. The connecting rod 41 is welded to the upper part of the mounting frame 1, the feeding frame 42 is welded to the lower part of the connecting rod 41, and the partition frame 43 is welded to the bottom of the feeding frame 42.

[0039] When using the device, the staff stacks multiple optical lenses in the feed frame 42. At this time, the optical lens at the bottom is on the conveyor belt 312 and is supported by the conveyor belt 312, and the next optical lens is located in the partition frame 43. When the conveyor belt 312 rotates, the partition 313 will also rotate, thereby pushing the bottom optical lens away, and the next optical lens will fall to the right side of the next partition 313, and the next optical lens will be pushed away by the next partition 313. In this way, the optical lenses can be continuously dropped onto the conveyor belt 312 for easy transportation.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, it also includes a correction mechanism 5, which can correct the position of the optical lens. The correction mechanism 5 includes a guide rod 51, a pressure frame 52, a correction plate 53, a first guide frame 54, a rack 55, a first spring 56 and a second spring 57. The guide rod 51 is welded to the lower left part of the mounting frame 1, and the pressure frame 52 is slidably connected to the guide rod 51. The correction plate 53 is welded to the upper right part of the pressure frame 52, and the correction plate 53 is located below the detector 2. The first guide frame 54 is connected to the upper left part of the mounting plate 32, and the rack 55 is slidably connected to the first guide frame 54. The missing gear shaft 35 rotates to engage with the rack 55, and the rack 55 moves downward to contact the left part of the pressure frame 52. The first spring 56 is connected between the rack 55 and the first guide frame 54, and the second spring 57 is connected between the pressure frame 52 and the guide rod 51.

[0042] When using the device, when the missing gear shaft 35 rotates to engage with the rack 55, the missing gear shaft 35 continues to rotate to squeeze the rack 55 to slide downward, and the first spring 56 is deformed. When the rack 55 slides downward to contact with the pressure frame 52, the rack 55 continues to slide downward to push the pressure frame 52 to slide downward, and the second spring 57 is deformed. The pressure frame 52 slides downward and drives the correction plate 53 to move downward. The correction plate 53 moves downward to squeeze the optical lens to the center position, so that the optical lens is just below the detector 2 for easy detection. When the missing gear shaft 35 rotates to disengage from the rack 55, under the action of the first spring 56 resetting, the rack 55 slides upward and resets. At this time, under the action of the second spring 57 resetting, the pressure frame 52 drives the correction plate 53 to move upward and reset.

[0043] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a limiting mechanism 6, which can block the optical lens in the feed frame 42. The limiting mechanism 6 includes a second guide frame 61, a slide rail 62, a third spring 63 and a clamping plate 64. The second guide frame 61 is welded to the lower right part of the feed frame 42, and the slide rail 62 is slidably connected to the upper right part of the second guide frame 61. The left part of the pressing frame 52 is in contact with the slide rail 62, and a third spring 63 is connected between the slide rail 62 and the second guide frame 61. The third spring 63 is in a stretched state, and the lower part of the second guide frame 61 is slidably connected to the clamping plate 64, which can limit the position of the optical lens, and the clamping plate 64 is slidably connected to the slide rail 62.

[0044] When using the device, the card plate 64 presses the optical lens in the partition frame 43 to fix the optical lens in the partition frame 43. When the pressure frame 52 slides downward, the slide rail 62 slides downward under the action of the third spring 63 returning to its original position. The slide rail 62 slides downward to squeeze the card plate 64 to slide to the right and no longer clamps the optical lens. At this time, the optical lens in the partition frame 43 falls onto the conveyor belt 312. When the pressure frame 52 slides upward to contact the slide rail 62, the pressure frame 52 continues to slide upward to squeeze the slide rail 62 to slide upward. The third spring 63 is deformed, and the slide rail 62 slides upward to drive the card plate 64 to slide to the left to press the next optical lens. In this way, the next optical lens can be limited, making it convenient for the optical lenses to fall onto the conveyor belt 312 one by one.

[0045] like Figure 1 , Fig. 9 and Fig.10 As shown, it also includes a material return mechanism 7, which can push out the optical lens after inspection. The material return mechanism 7 includes a material return rack 71, a material return rod 72 and a fourth spring 73. The material return rack 71 is welded on the lower right part of the mounting frame 1, and the upper part of the material return rack 71 is slidably connected to the material return rod 72. The right part of the pressing frame 52 slides downward and contacts the material return rod 72. A fourth spring 73 is connected between the material return rod 72 and the material return rack 71.

[0046] When the device is used, when the pressure frame 52 slides downward until it contacts the return rod 72, the pressure frame 52 continues to slide downward to squeeze the return rod 72 to slide forward, the fourth spring 73 is deformed, and the return rod 72 slides forward to push the inspected optical lens forward, so that the optical lens moves to the return frame 71, making it convenient for the staff to take the optical lens. When the pressure frame 52 slides upward, under the action of the fourth spring 73 returning to its original position, the return rod 72 slides backward and returns to its original position.

[0047] like Figure 1 and Fig.11 As shown, it also includes a fill light mechanism 8, which can fill light for the optical lens component. The fill light mechanism 8 includes a fixed plate 81, an adjusting rod 82 and a fill light plate 83. The fixed plate 81 is welded to the middle position of the lower part of the mounting frame 1, and the front part of the fixed plate 81 is rotatably connected to the adjusting rod 82. The fill light plate 83 is threadedly connected to the adjusting rod 82, and the fill light plate 83 is slidably connected to the fixed plate 81.

[0048] When using the device, the fill light plate 83 can focus light onto the optical lens, which is convenient for the detector 2 to detect. At the same time, the staff can also rotate the adjustment rod 82 as needed. The rotation of the adjustment rod 82 can drive the fill light plate 83 to slide up and down, thereby adjusting the height of the fill light plate 83.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
