Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a shearing machine for processing plastic lenses. Background Technology

[0002] A shearing machine is a machine used to cut thin sheet materials into a certain shape, typically used for paper, lenses, etc.

[0003] In the prior art, the patent with authorization announcement number CN 213679004 U discloses a feeding device for a radiation-proof lens cutting machine. It uses a suction cup to move down, pick up the sheet material, move up and release it, and transfer it to the receiving plate. The receiving plate then transfers it to the processing table of the cutting machine, mimicking manual feeding. After the suction cup finishes feeding, it needs to return to its original position and repeat the feeding action. The feeding interval is relatively long, which reduces the processing efficiency. Utility Model Content

Detailed Implementation

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] Please see Figure 1-4 This embodiment provides a technical solution: a shearing machine for processing plastic lenses, including a frame 1, a PLC controller 2 installed on the side of the frame 1, a drive mechanism 4 installed on the top of the frame 1, a connecting box 7 fixed on the drive part of the drive mechanism 4, material picking units 3 evenly arranged on the side of the connecting box 7, a vacuum unit 5 installed on the inner bottom of the frame 1, the vacuum unit 5 communicating with the inside of the connecting box 7, a material box 8 fixed on the inner bottom of the frame 1, a pushing unit 6 installed on the inner side of the material box 8, and the PLC controller 2 electrically connected to an external power supply.

[0020] The drive mechanism 4 includes a worm gear 41, a connecting shaft 42, a worm wheel 43, and a servo motor 44. The connecting shaft 42 is rotatably mounted on the frame 1, and the connecting box 7 is fixed to the bottom of the connecting shaft 42. The worm gear 41 is rotatably mounted inside the support of the frame 1. The servo motor 44 is mounted on the side of the support of the frame 1. The output shaft of the servo motor 44 is fixedly connected to one end of the worm gear 41. The worm gear 41 meshes with the worm wheel 43, and the worm wheel 43 is sleeved and fixed to the top of the connecting shaft 42. The servo motor 44 is electrically connected to the PLC controller 2. The output shaft of the servo motor 44 drives the worm gear 41 to rotate. The worm gear 41 meshes with the worm wheel 43. The worm wheel 43 drives the connecting box 7 to rotate through the connecting shaft 42. The connecting box 7 drives the material picking unit 3 to rotate, thereby moving the sheet material to the processing table of the shearing machine. This facilitates continuous feeding operations, thereby reducing the feeding interval time and improving processing efficiency.

[0021] The material pickup unit 3 includes a vacuum suction cup 31 and a branch pipe 32. The branch pipe 32 is arranged in a rotating array on the side of the connecting box 7 and communicates with the inside of the connecting box 7. The vacuum suction cup 31 is mounted on the end of the branch pipe 32. The material pickup unit 3 also includes a switching valve 33, which is mounted on the branch pipe 32 and electrically connected to the PLC controller 2 via an electric slip ring. The vacuum pump unit 5 includes a vacuum pump 51, a vacuum tube 52, and a rotary joint 53. The vacuum pump 51 is installed on the inner bottom of the frame 1 and communicates with the inside of the connecting box 7 via the vacuum tube 52. The end of the vacuum tube 52 is connected to the PLC controller 2 via the rotary joint 53. The bottom of the connecting box 7 is rotatably connected, and the vacuum pump 51 is electrically connected to the PLC controller 2. When the switch valve 33 is opened, the vacuum pump 51 evacuates the inside of the connecting box 7 through the vacuum tube 52. The connecting box 7 evacuates the vacuum suction cup 31 through the branch pipe 32. The vacuum suction cup 31 adsorbs and fixes the sheet material. The connecting box 7 drives the material picking unit 3 to rotate, thereby moving the sheet material to the processing table of the shearing machine. Then, the switch valve 33 is closed, the vacuum suction cup 31 loses its adsorption effect on the sheet material, and the sheet material falls onto the processing table of the shearing machine under the action of gravity. It is convenient to load and unload materials and easy to use.

[0022] The feeding unit 6 includes an electric push rod 61 and a top plate 62. The electric push rod 61 is mounted on the frame 1, and the top plate 62 is fixed to the telescopic end of the electric push rod 61. The top plate 62 is movably disposed inside the material box 8. The electric push rod 61 is electrically connected to the PLC controller 2. The telescopic end of the electric push rod 61 drives the top plate 62 to move up and down. The top plate 62 moves inside the material box 8, thereby pushing the sheet material in the material box 8 to a position that is easy for the vacuum suction cup 31 to pick up, ensuring the rationality of the design.

[0023] The working principle of the plastic lens processing shearing machine provided by this utility model is as follows: The telescopic end of the electric push rod 61 drives the top plate 62 to move up and down. The top plate 62 moves in the material box 8, thereby pushing the sheet material in the material box 8 to a position that is easy for the vacuum suction cup 31 to pick up. Then, the switch valve 33 is opened, and the vacuum pump 51 evacuates the connection box 7 through the vacuum tube 52. The connection box 7 evacuates the vacuum suction cup 31 through the branch pipe 32. The vacuum suction cup 31 adsorbs and fixes the sheet material. Then, the output shaft of the servo motor 44 drives the worm gear 41 to rotate. The worm gear 41 meshes with the worm wheel 43. The worm wheel 43 drives the connection box 7 to rotate through the connecting shaft 42. The connection box 7 drives the material picking unit 3 to rotate, thereby moving the sheet material to the processing table of the shearing machine. Then, the switch valve 33 is closed, the vacuum suction cup 31 loses its adsorption effect on the sheet material, and the sheet material falls onto the processing table of the shearing machine under the action of gravity.
