A material taking device 3 is arranged above the material rack 2, a first conveyor platform 4 is arranged on one side of the material rack 2, a first conveyor belt 41 is arranged on the first conveyor platform 4, two first conveyor belts 41 are arranged, a first support plate 42 is arranged between the two first conveyor belts 41, a second conveyor platform 5 connected with the first conveyor platform 4 is arranged in the combined frame 1, the second conveyor platform 5 is provided with a second conveyor belt 51 corresponding to the position of the first conveyor belt 41, a second support plate 52 is arranged between the two second conveyor belts 51, a thermal printing device 6 is arranged above the second conveyor platform 5, the thermal printing device 6 is provided with a thermal printing plate 61, and a lifting cylinder 62 for driving the thermal printing plate 61 to move up and down, and third conveyor belts 63 that can cooperate with the second conveyor belt 51 are arranged on both sides of the thermal printing plate 61; an auxiliary roller a11 is arranged in the combined frame 1, an auxiliary roller b12 is arranged between the first conveyor platform 4 and the second conveyor platform 5, and a pressure roller device 13 is arranged in the combined frame 1. In the scheme of the present utility model, Figure 7As shown, the packaging film for packaging lenses is composed of a bottom film 7 and a top film 8, both of which are release films. The bottom film 7 passes through the first conveyor belt 41, the second conveyor belt 51, and the pressing roller device 13 in sequence. The auxiliary roller a11 is arranged above the auxiliary roller b12. The top film 8 first passes through the auxiliary roller a11 and the auxiliary roller b12, then passes under the thermal printing device 6, and finally passes through the pressing roller device 13. Since the auxiliary roller b12 is arranged between the first conveyor platform 4 and the second conveyor platform 5, the path of the top film 8 will not affect the material picking device 3. In the specific packaging process, the material picking device 3 grabs The lenses are placed on the bottom film 7 passing through the first conveyor 4, and the first support plate 42 supports and positions the bottom film 7. After the lenses are placed, the bottom film 7 carries the lenses and moves to the second support plate 52 of the second conveyor 5. The lifting cylinder 62 drives the hot printing plate 61 to move downward, pressing the top film 8 downward, so that the top film 8 and the bottom film 7 are pressed together. The second conveyor belt 51 and the third conveyor belt 63 cooperate with each other to press the edges of the top film 8 and the bottom film 7, and the lenses are packaged. Finally, the packaged lenses are discharged through the pressing roller device 13. The lens packaging process is fully automatic, saving manpower, and the lens packaging speed is fast and the quality is high. Workers place a large number of lenses in the material rack 2, and the lenses are grabbed by the material taking device 3 and placed at a specific position on the first conveyor 4, so as to achieve automatic loading of lens packaging and save workers' loading time.

[0025] A crossbeam 14 is provided in the assembly rack 1, and the crossbeam 14 extends from above the material rack 2 to above the first conveying platform 4. A slide rail 15 is provided on the crossbeam 14, and the material picking device 3 is movably connected to the slide rail 15. A first motor 16 is provided on the crossbeam 14 to drive the material picking device 3 to move along the slide rail 15. The first motor 16 drives the material picking device 3 to move back and forth between the material rack 2 and the first conveying platform 4, and the lens picking and loading speed is fast.

[0026] The material rack 2 is provided with a lifting plate 21, and a second motor 22 is provided at the bottom of the material rack 2 to drive the lifting plate 21 to rise and fall. The material rack 2 has a certain depth, and the lenses are stacked on the lifting plate 21. When the lenses at a certain height are consumed, the second motor 22 drives the lifting plate 21 to rise to a certain height, so that the material taking device 3 can grab the lenses at a specified position.

[0027] The material taking device 3 is provided with a cylinder a31 that can extend downward, and a third motor 32 is provided at the extended end of the cylinder a31, and a material taking frame 33 is provided at the end of the rotating shaft of the third motor 32, and a plurality of suckers 34 are provided on the material taking frame 33. The suckers 34 are externally connected to a suction pipe, and the suckers 34 can absorb the lenses. In a specific feeding cycle, the material taking device 3 moves to the top of the material frame 2, and the third motor 32 drives the material taking frame 33 to rotate to a specified angle, and then the cylinder a31 drives the material taking frame 33 to descend, so that the suckers 34 contact and absorb the lenses, and then the third motor 32 and the cylinder a31 drive the material taking frame 33 to reset in turn, and the material taking device 3 moves to the top of the first conveying platform 4, and the cylinder a31 drives the material taking frame 33 to descend, so that the lenses are placed on the bottom film 7, and then the material taking frame 33 is reset, and the material taking device 3 moves to the material frame 2 to continue the next feeding cycle, thereby achieving the automatic lens feeding process.

[0028] A cylinder b43 is provided below the first support plate 42, and the cylinder b43 can drive the first support plate 42 to move up and down. The upward surface of the bottom film 7 has a certain degree of stickiness, and the lens is not easy to slide after being placed on the bottom film 7. However, since the two side edges of the bottom film 7 abut against the first conveyor belt 41, the middle of the bottom film 7 will sink slightly. When the material taking device 3 places the lens, the cylinder b43 drives the first support plate 42 to rise, and slightly lifts the bottom film 7, so that the position of the bottom film 7 for placing the lens is flat, avoiding the problem of the lens misalignment causing the packaging quality to be damaged.

[0029] A cylinder c53 is provided below the second support plate 52, and the cylinder c53 can drive the second support plate 52 to rise and fall. Similarly, the cylinder c53 drives the second support plate 52 to slightly lift the bottom film 7, so that the thermal projection device can press the top film 8 more accurately.

[0030] The heat printing plate 61 is provided with a limit plate 64, and a heat printing stripe 65 is provided in the middle of the heat printing plate 61. When the packaging machine is running, the limit plate 64 and the heat printing stripe 65 are electrically heated to a certain temperature for preheating. When the heat printing plate 61 moves downward to press the top film 8 onto the bottom film 7, the limit plate 64 and the heat printing stripe 65 are further heated to form a heat-sealed package between the top film 8 and the bottom film 7. Among them, the limit plate 64 is provided at the edge of the heat printing plate 61 and has a certain thickness, which is greater than the thickness of the lens, so as to avoid the second support plate 52 and the heat printing plate 61 from squeezing each other and causing damage to the lens; among them, the thickness of the heat printing stripe 65 is consistent with that of the limit plate 64, and the heat printing stripe 65 is in a grid shape, which is used to separate adjacent lenses, so as to avoid squeezing and collision between the lenses after packaging, and the lens packaging quality is high.

[0031] The roller device 13 is provided with a first roller 131 and a second roller 132 arranged in an upper and lower order, and a roller cover 133 is provided on the first roller 131 and the second roller 132. The roller cover 133 is made of soft foam material, and the lens and the packaging will not be excessively squeezed and damaged after the packaging film is rolled.

[0032] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
