[0030] Embodiment

[0031] This embodiment provides a lens blanking and receiving device. Refer to Figures 1-3, including a frame 10, on which a variable-spacing suction cup assembly 20 is provided. The variable-spacing suction cup assembly 20 includes a plurality of articulated parallelogram link mechanisms 21 and a mounting seat 22. Each parallelogram link mechanism 21 is composed of a first link 211 and a second link 212 that are cross-articulated, and two adjacent first links 211 and second links 212 are articulated at their ends to form a parallelogram structure. At the bottom of the articulated ends of the plurality of links of the parallelogram link mechanism 21, a suction cup bracket 23 is respectively connected. A vacuum suction cup for adsorbing the lens is provided on the suction cup bracket 23. In this embodiment, the lens is in a cuboid structure, and two vacuum suction cups are installed on each suction cup bracket 23, which can stably adsorb the lens to facilitate subsequent transplanting and positioning.

[0032] In this embodiment, two parallel guide rods are provided on the mounting seat 22, and a plurality of suction cup brackets 23 are slidably connected to the guide rods, so that each suction cup can slide along the guide rods in the horizontal direction to adjust the spacing. In order to drive the parallelogram link mechanism 21 to act, a first driving cylinder 24 is also provided on the mounting seat 22, and its action output end is articulated with the first link 211 of the parallelogram link mechanism 21 at the end. Through the telescopic movement of the cylinder, the entire variable-spacing suction cup assembly 20 realizes the variable-spacing function, and the variable-spacing action of the lens on the vacuum suction cup is realized.

[0033] To further improve the automatic operation function of the device, a linear module 31 horizontally arranged perpendicular to the guide rod direction is also connected to the frame 10. The action output end of the linear module 31 is connected with a mounting plate 32, and a second driving cylinder 33 for driving the mounting seat 22 to move in the Z-axis direction is provided on the mounting plate 32. In this way, the entire variable-spacing suction cup assembly 20 can not only adjust the suction cup spacing in the horizontal direction, but also move in the vertical direction, so as to realize the adsorption and placement of the lens by the variable-spacing suction cup assembly 20.

[0034] A lens conveyor belt 40 is provided below the variable-spacing suction cup assembly 20 for conveying the lenses to be unloaded. The lenses flow in from the starting end of the movement of the lens conveyor belt 40 from the previous station. A lens limit blocking block is provided at the end of the lens conveyor belt 40 to ensure that the lenses are adsorbed at a suitable position, and a plurality of lenses are adsorbed by the variable-spacing suction cup assembly 20 after approaching each other.

[0035] In addition, this embodiment further includes a cartridge transplanting mechanism 50, which is located at one end of the linear module 31 away from the lens conveyor belt 40. The cartridge transplanting mechanism 50 includes a tray moving line 51 arranged parallel to the guide rod. At both ends of the tray moving line 51, a lifting cartridge bin 52 with the same structure is respectively provided, which are a cartridge feeding bin for empty cartridge placement and a cartridge recycling bin for full cartridge recycling.

[0036] The pallet moving line 51 is composed of a pallet rack 511 and a pallet 512 slidably arranged on the pallet rack 511. A synchronous belt drive mechanism is arranged below the pallet rack 511 to drive the movement of the pallet 512. The lifting magazine 52 includes a magazine frame 521. Multiple boxes for empty or full lenses can be placed inside the magazine frame 521. Third driving cylinders 522 arranged horizontally and fourth driving cylinders 523 arranged in the Z-axis direction are respectively provided at the bottom of both sides of the magazine frame 521. A fork 524 is fixedly connected to the action output part of the fourth driving cylinder 523, which is used to push up the box for feeding or recycling.

[0037] During actual operation, after multiple lenses are brought closer, they are adsorbed by the variable pitch suction cup assembly 20. The linear module 31 drives the variable pitch suction cup assembly 20 to move to the other end. At the same time, the fork 524 of the box feeding magazine is inserted into the bottommost box, and then the fourth driving cylinder 523 extends to lift the box. The pallet moves below the box feeding magazine. After the fork 524 disengages from the box, it is inserted again between the second-bottom layer and the bottom layer boxes to lift the empty box above the second-bottom layer and separate it from the bottom layer box. The pallet drives the box to move below the variable pitch suction cup assembly 20. The first driving cylinder 24 extends to push the multiple suction cup brackets 23 away from each other until the distance between the lenses meets the distance between the slots on the box, so that the lenses correspond to the slots on the box one by one, facilitating the placement of the lenses into the box after variable pitch.

[0038] After the lenses are placed into the box after variable pitch, the variable pitch suction cup assembly 20 moves to the lens adsorption station at the other end. When there is a full box in the box recycling magazine, the fork 524 of the box recycling magazine is inserted into the bottommost box, and then the fourth driving cylinder 523 extends to lift the box. The pallet moves below the box recycling magazine. After the fork 524 disengages from the box, it is inserted again between the pallet and the upper bottom layer box to lift the box and separate it from the pallet. The pallet returns to the material receiving station between the two lifting magazines 52.

[0039] Enlightened by the above ideal embodiments according to the present application, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
