[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0019] The lens rack changing mechanism, such as Figure 1 to Figure 2 As shown, the rack trolley 1 includes a support frame 52. The rack trolley 1 is used for placing rack bins. The rack trolley 1 has a plurality of placement areas 11 for placing rack bins. The plurality of placement areas 11 are arranged along the vertical direction to make full use of the vertical space so that more rack bins can be placed in a limited horizontal area, which can effectively improve space utilization and is more suitable for production environments with limited space.
[0020] A plurality of rollers 10 are provided at the bottom of the rack trolley 1 to facilitate moving the rack trolley 1 and changing the position of the rack trolley 1 .
[0021] A plurality of rotating downward pressing cylinders 9 are provided on the support frame 52, and the output ends of the rotating downward pressing cylinders 9 can press the rack trolley 1 onto the support frame 52. During the production process, the output ends of the rotating downward pressing cylinders 9 cooperate to press the rack trolley 1 onto the support frame 52 to ensure the stability of the rack trolley 1. When the rack bin on the rack trolley 1 is full of lenses, the output ends of the rotating downward pressing cylinders 9 extend out and rotate away from the rack trolley 1, and the rack trolley 1 can be pushed away from the support frame 52 at this time.
[0022] A supporting beam 3 is slidably arranged on the supporting frame 52, and a lifting driving component 4 for driving the supporting beam 3 to move in the vertical direction is arranged on the supporting frame 52. A mounting frame 5 and a lateral driving component 6 for driving the mounting frame 5 to move in the lateral direction are slidably arranged on the supporting beam 3. A frame taking component 7 and a longitudinal driving component 8 for driving the frame taking component 7 to move in the longitudinal direction are slidably arranged on the mounting frame 5. It should be noted that in this embodiment, the lifting driving component 4, the lateral driving component 6 and the longitudinal driving component 8 all adopt a synchronous belt linear module, which can be respectively arranged in the vertical direction, the lateral direction and the longitudinal direction. The synchronous belt linear module specifically includes a motor, a driving pulley, a driven pulley and a synchronous belt. The output end of the motor is connected to the driving pulley, and the driving pulley and the driven pulley are connected through a synchronous belt transmission. The supporting beam 3, the mounting frame 5 and the frame taking component 7 are respectively connected to the corresponding synchronous belts, and the supporting beam 3, the mounting frame 5 and the frame taking component 7 all slide through the cooperation of the slide rail and the slider.
[0023] The rack taking component 7 can clamp a rack bin fully loaded with lenses and place it on the rack trolley 1 and clamp an empty rack bin from the rack trolley 1. It should be noted that under the action of the lifting drive component 4, the transverse drive component 6 and the longitudinal drive component 8, the rack taking component 7 can move in the vertical, transverse and longitudinal directions, so as to clamp a rack bin fully loaded with lenses and place it on the rack trolley 1 and clamp an empty rack bin from the rack trolley 1, replace the empty rack bin with the empty rack bin and continue loading. The rack taking of the fully loaded lens rack bin and the replacement of the empty rack bin are completed in an automated manner, which can effectively improve production efficiency and reduce labor costs.
[0024] The rack removal assembly 7 includes a base plate 71 , a rotating cylinder 72 , a movable plate 73 and a clamping member 74 . The rotating cylinder 72 is mounted on the base plate 71 , an output end of the rotating cylinder 72 is connected to the movable plate 73 , and the clamping member 74 is mounted on the movable plate 73 .
[0025] The clamping member 74 is used to clamp the rack, and the clamping member 74 includes two driving cylinders 741, two fisheye joints 742, a base plate 743 and two clamping seats 744. The output ends of the two driving cylinders 741 are respectively connected to the two fisheye joints 742, and the two clamping seats 744 are slidably arranged on the base plate 743. The two fisheye joints 742 are respectively rotatably connected to the two clamping seats 744. The two driving cylinders 741 can respectively drive the two clamping seats 744 to approach or move away from each other, and the output ends of the two driving cylinders 741 are extended or retracted, thereby driving the two clamping seats 744 to move, so that the two clamping seats 744 can cooperate with each other to clamp the rack.
[0026] The rotating cylinder 72 can drive the movable plate 73 to rotate and drive the clamping member 74 and the rack bin to rotate to achieve reversal. It should be noted that when the rack bin full of lenses is taken out, it cannot be directly placed in the placement area 11 of the rack trolley 1. The rotating cylinder 72 is required to drive the movable plate 73 to rotate, and the movable plate 73 drives the clamping member 74 and the rack bin to rotate, so that the rack bin can be placed in the placement area 11 of the rack trolley 1. When the empty rack bin is taken out from the placement area 11 of the rack trolley 1, it also needs to be reversed to replace it to the specified position.
[0027] The rotating cylinder 72 can drive the movable plate 73 to rotate to the bottom of the mounting frame 5 and drive the clamping member 74 and the shelf bin to rotate to the bottom of the mounting frame 5. It should be noted that by rotating the movable plate 73, the clamping member 74 and the shelf bin to the bottom of the mounting frame 5, the space occupied during the movement process is reduced, other production stations are effectively avoided, and the space utilization rate is improved.
[0028] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
