Technical Field

[0001] This utility model relates to the field of plastic lens production technology, and in particular to a finished product removal device for plastic lens production. Background Technology

[0002] Plastic lenses are widely used in various eyeglasses, optical instruments, and other fields. After injection molding, plastic lenses require trimming and polishing to meet processing precision requirements. During transportation, each lens needs to be handled individually, resulting in a heavy workload for workers. Furthermore, workers' direct contact with the lenses can leave marks that affect subsequent processing. Additionally, the surface finishing and polishing processes inevitably generate fine powder and other impurities, which can easily scratch the lens surface and affect product quality.

A cylinder 7 is provided on the side of the third housing 9 away from the first housing 2. The piston of the cylinder 7 is connected to the third housing 9 and the cylinder 7 controls the distance between the third housing 9 and the first housing 2. Air nozzles 23 are distributed on the side of the third housing 9 and spray airflow toward the suction cups 17.

[0022] The first housing 2 has a first motor 4 at one end, the output shaft of the first motor 4 passes through the end face of the first housing 2, and is provided with a transmission screw 11 coaxially arranged. The other end of the transmission screw 11 is rotatably connected to the inner wall of the other end of the first housing 2. The lower surface of the first housing 2 is provided with an axially arranged sliding groove 12.

[0023] The upper surface of the second housing 5 is provided with a slider 13, which slides in the slide groove 12. The upper end of the slider 13 is provided with a sleeve 14, which is sleeved on the transmission screw 11 and threadedly connected to the transmission screw 11. The rotation of the transmission screw 11 drives the sleeve 14 to move laterally. One end of the second housing 5 is provided with a second motor 6, the output shaft of which passes through the end face of the second housing 5 and is provided with a coaxial bidirectional lead screw 20. The other end of the bidirectional lead screw 20 is rotatably connected to the inner wall of the second housing 5. Two pressure blocks 21 are symmetrically provided on the bidirectional lead screw 20, and two suction cups 17 are respectively provided in cooperation with the two pressure blocks 21. The bottom surface of the inner wall of the second housing 5 is symmetrically provided with two longitudinally arranged limiting tubes 15, the lower end of which passes through the second housing 5. The two suction cups 17 are respectively provided at the lower ends of the two limiting tubes 15.

[0024] The pressure block 21 is threadedly connected to the bidirectional lead screw 20. The bidirectional lead screw 20 rotates to drive the two pressure blocks 21 to move closer or further away. The lower surface of the pressure block 21 is a sloping structure, and the upper surface of the pressure block 21 is provided with a roller 22. The roller 22 abuts against the top surface of the inner wall of the second housing 5.

[0025] The limiting tube 15 is provided with a connecting rod 16. The lower end of the connecting rod 16 passes through the limiting tube 15 and is rotatably connected to the suction cup 17. The upper end of the connecting rod 16 is provided with a fixing plate 18. The lower end of the pressure block 21 presses on the fixing plate 18, causing the connecting rod 16 to move downward. A spring 19 is sleeved on the connecting rod 16. The upper end of the spring 19 is connected to the fixing plate 18, and the lower end of the spring 19 is connected to the limiting tube 15.

[0026] A three-way pipe 10 is provided on one side of the third housing 9. The two air outlet ends of the three-way pipe 10 pass through the third housing 9 and are arranged parallel to each other inside the third housing 9. The air nozzle 23 is connected to the two air outlet ends of the three-way pipe 10. The air inlet end of the three-way pipe 10 is connected to an external air pump. The airflow enters each air nozzle 23 through the three-way pipe 10, thereby generating a high-speed airflow on the surface of the finished plastic lens and removing dust from its surface.

[0027] The third housing 9 is provided with an annular transmission belt 24 on the side near the first housing 2. Drive rollers 25 are distributed inside the transmission belt 24. The drive rollers 25 drive the transmission belt 24 to rotate. The side of the finished plastic lens abuts against the surface of the transmission belt 24. The rotation of the transmission belt 24 drives the finished plastic lens to rotate, so that the airflow can more thoroughly clean the dust on the surface of the plastic lens.

[0028] The finished product removal device for plastic lens production described in this embodiment operates as follows: When in use, the first motor 4 is activated, driving the transmission screw 11 to rotate. The rotation of the transmission screw 11 causes the sleeve 14 to move laterally, thereby moving the second housing 5 towards the plastic lens and aligning the suction cup 17 with the lens. The second motor 6 is then activated, causing the bidirectional screw 20 to rotate, moving the two pressure blocks 21 closer together or further apart, so that the lower ends of the pressure blocks 21 press against the fixed plate 18, moving the connecting rod 16 downwards, thus allowing the suction cup 17 to adhere to the surface of the plastic lens. The second motor 6 rotates in the opposite direction, causing the connecting rod 16 to rise upwards. The first motor 4 rotates in the opposite direction, causing the second housing 5 to retract. The cylinder 7 pushes the third housing 9 towards the lens, causing the surface of the transmission belt 24 to contact the edge of the plastic lens. The airflow generated by the air pump enters each nozzle 23 through the three-way pipe 10, thereby generating a high-speed airflow on the surface of the finished plastic lens, removing surface dust. The rotation of the transmission belt 24 causes the finished plastic lens to rotate, making the airflow more thorough in cleaning the surface dust of the plastic lens.
