[0002] In the production process of prescription lenses, lens pad printing is one of the essential steps. Lens pad printing is a technique commonly used for marking or printing on the surface of optical elements. During lens pad printing, first, a pattern or text is printed on a special pad printing template, then the template is aligned with the surface of the lens to be printed, and appropriate pressure is applied to transfer the ink to the lens surface, finally forming a clear printed pattern.

[0040] The following further elaborates on the present application in conjunction with the attached Figures 1-5 For a more detailed description of the present application.

[0041] As Figures 1-2 , a loading and unloading device for a lens pad printer includes a feeding component 1. Among them, a feeding belt 11 is provided on the feeding component 1. Below the feeding belt 11, a first speed regulating motor 12 is provided. One end of the first speed regulating motor 12 is fixedly connected to a first driving shaft 13. The first driving shaft 13 is connected to a first driven shaft 14 through a belt, so that when the first speed regulating motor 12 rotates, the first driven shaft 14 is driven to move by the first driving shaft 13. The first driven shaft 14 is in contact with the feeding belt 11 to drive the feeding belt 11 to move along its circumferential direction; on both sides of the feeding belt 11, two first belt conveyor side plates 15 are relatively and spaced apart for protecting the feeding belt 11 to achieve normal operation;

[0042] As Figure 5At the other end of the feeding assembly 1, an induction synchronous belt conveying assembly 4 is abutted and arranged. A conveying synchronous belt 41 coaxial with the feeding belt 11 is arranged on the induction synchronous belt conveying assembly 4. Among them, the conveying synchronous belt 41 moves in the same direction as the feeding belt 11. On both sides of the conveying synchronous belt 41 close to the feeding assembly 1, lens position adjusting plates 46 are oppositely arranged to quickly adjust the lens position. On the side of the conveying synchronous belt 41 far from the feeding assembly 1, a lens in-place sensor 45 is arranged.

[0043] As Figure 3 On one side parallel to the feeding assembly 1, a discharging assembly 2 is arranged at intervals. Among them, a discharging belt 21 is arranged on the discharging assembly 2. Below the discharging belt 21, a second speed regulating motor 22 is arranged. One end of the second speed regulating motor 22 is fixedly connected with a second driving shaft 23. The second driving shaft 23 is connected with a second driven shaft 24 through a belt, so that when the second speed regulating motor 22 rotates, the second driven shaft 24 is driven to move by the second driving shaft 23. The second driven shaft 24 is abutted against the discharging belt 21 to drive the discharging belt 21 to move along its circumferential direction; on both sides of the discharging belt 21, two second belt machine side plates 25 are oppositely arranged at intervals to protect the feeding belt 11 to realize normal operation; on the side of the second belt machine side plate 25 close to the feeding assembly 1, a lens inductor 26 is further arranged to detect the movement and position of the lens after pad printing.

[0044] As Figure 4 Above the discharging assembly 2 and the induction synchronous belt conveying assembly 4, a grasping assembly 3 is arranged at intervals. The grasping assembly 3 is provided with a horizontal moving cylinder 34. The horizontal moving cylinder 34 is vertically arranged above the discharging assembly 2 and the induction synchronous belt conveying assembly 4. One end of the horizontal moving cylinder 34 is fixedly connected with a vertical moving cylinder 33. At the end of the vertical moving cylinder 33, a servo rotating structure 32 is arranged. At one end of the servo rotating structure 32, two groups of clamping jaws 31 are arranged. The two groups of clamping jaws 31 can move in the 180° direction under the rotation of the servo rotating structure 32.

[0045] The operation steps of the loading and unloading device for the lens pad printer of the present application include:

[0046] (1) Place a row of lenses to be pad printed on the discharging belt 21 of the discharging assembly 2. Under the rotation of the first speed regulating motor 12, the lenses to be pad printed are continuously conveyed to the induction synchronous belt conveying assembly 4 in sequence.

[0047] (2) The induction synchronous belt conveyor assembly 4 quickly takes a lens from the discharge belt 21 to the top of the lens in place sensor 45 each time. When the lens passes through the lens position adjustment plate 46, the lens can be quickly corrected to prevent the lens from being misaligned and affecting the subsequent grabbing action. When the lens in place sensor 45 senses the lens, the feed assembly 1 and the induction synchronous belt conveyor assembly 4 stop running at the same time. Until the lens above the lens in place sensor 45 is taken away, the feed assembly 1 and the induction synchronous belt conveyor assembly 4 resume running and repeat this action continuously.

[0048] (3) The gripping component 3 grabs the lens above the lens in place sensor 45 through the gripper 31 and transports it to the lens workbench. The discharge gripper 31 takes the lens on the lens workbench. The servo rotating structure 32 swaps the positions of the two sets of grippers 31. The gripper 31 places the lens on the lens workbench. When the servo rotating structure 32 is reset, the gripping component 3 returns to the top of the feeding component 1 and places the lens on the gripper 31 on the discharge belt 21 of the discharge component 2. At the same time, the gripper 31 takes the next lens above the lens in place sensor again. This action is repeated continuously.

[0049] (4) The discharge belt 21 continuously transports the printed lenses. When the lens sensor 26 detects that no lenses are passing through, the discharge belt 21 stops running. When the lens sensor 26 senses that there are lenses, the discharge assembly 2 starts running again, thereby realizing the automatic and reciprocating loading and unloading steps of lens pad printing.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
