Description

Technical Field

[0001] This utility model relates to the technical field of dynamic chamfering and polishing machines, and in particular to an automatic chamfering and polishing machine for processing glass lens molds. Background Technology

[0002] In the field of optical lens manufacturing, the concave edges of glass lens molds need to be chamfered and polished to achieve specific process requirements and mirror effects. Currently, the traditional processing method commonly used in the industry is manual operation. Operators need to manually clamp the lens molds one by one onto a special manual chamfering machine for chamfering. After completion, they are disassembled and manually cleaned with a water gun. Then, they are clamped onto a manual polishing machine for polishing. After polishing, they are manually cleaned again and dried with an air gun before being transferred to the next process.

[0003] This traditional manual operation mode has many drawbacks: First, the entire process relies heavily on frequent manual loading, unloading, clamping, and transfer operations, resulting in high labor costs and low production efficiency. Second, because lens molds have various diameters and curvatures, a wide variety of clamping fixtures are required, greatly complicating and inconvenient production management, fixture storage, and replacement. Third, during manual chamfering, the significant human intervention makes it easy to apply uneven pressure or angles, leading to edge chipping, reduced product yield, and a significantly increased risk of rework or even scrap. Therefore, developing equipment that can achieve automated, continuous production and effectively guarantee processing quality has become a pressing technical problem for the industry.

It includes a frame 21 made of aluminum profiles, with universal wheels 22 with brakes installed at the bottom of the frame 21, a handle 23 at the top, and a bracket 24 inside for layered support of material trays.

[0045] The specific operating procedure is as follows:

[0046] 1. Initial loading: The operator pushes the material pallet full of lens molds into the bottom of the loading silo 3 through the material trolley 2.

[0047] 2. Material Lifting and Retrieval: The servo motor 33 of the loading hopper 3 drives the ball screw mechanism 31 to lift the pallet lifting platform 32, bringing the uppermost pallet to the retrieval position. The X-axis linear guide module 111 and Y-axis linear guide module 112 of the transfer mechanism 11 work together to move the vacuum suction cup assembly 114 above the pallet. The transfer cylinder 113 drives the vacuum suction cup to descend, pick up a lens mold, rise, and move it above the loading conveyor line 5, releasing the mold onto the conveyor line.

[0048] 3. Feeding and Centering: The stepper motor 51 of the feeding conveyor line 5 drives the synchronous belt transmission mechanism 52 to transport the mold forward. After the reflective photoelectric switch 55 detects the mold, the pneumatic finger 54 actuates to clamp the mold and center it, and then releases it.

[0049] 4. Turntable loading and transfer: When the mold is transported to the end loading station, the slide cylinder 72 of the corresponding station on the turntable mechanism 7 extends, and the turntable suction cup 73 picks up the mold and retracts. The cam divider 71 drives the turntable to rotate one station, sending the mold to the chamfering mechanism 8, polishing mechanism 9 and cleaning and drying mechanism 10 for processing in sequence.

[0050] 5. Chamfering and Polishing Operations: At the chamfering station, the chamfering motor 83 drives the chamfering grinding head 81 to rotate at high speed, while the cutting fluid nozzle 82 sprays cutting fluid supplied by the polishing tank 12, and the rotary suction cup presses down on the mold to complete the chamfering. At the polishing station, the polishing motor 91 drives the polishing cup 92 to rotate at high speed, the polishing fluid nozzle 93 sprays polishing fluid, and the rotary suction cup presses down on the mold to complete the polishing.

[0051] 6. Cleaning and Drying: After the mold enters the cleaning chamber 101 of the cleaning and drying mechanism 10, the parallel opening and closing cylinder 102 closes the chamber door 103. The clean water nozzle 104 sprays water onto both the upper and lower surfaces of the mold, and then the air nozzle 105 dries it. After completion, the chamber door is opened.

[0052] 7. Turntable unloading: The finished mold is transferred to the unloading station by the turntable. The slide cylinder 72 extends and the turntable suction cup 73 releases the mold and places it at the beginning of the unloading conveyor line 6.

[0053] 8. Unloading, Tilting, and Conveying: The rotary cylinder 63 at the beginning of the unloading conveyor line 6 drives the unloading vacuum suction cup 64 to pick up the mold, rotate it 180°, and then release it, causing the mold to fall face down into the designated position of the synchronous belt drive mechanism 62. The stepper motor drives the synchronous belt to convey the mold to the left.

[0054] 9. Finished Product Warehousing: The transfer mechanism 11 picks up the processed molds from the end of the unloading conveyor line 6, transfers them, and places them on the material pallet in the unloading silo 4. The pallet lifting platform 32 of the unloading silo gradually descends as the pallet becomes full until all molds are stored. Finally, the operator uses the material trolley 2 to transport the entire pallet of finished products away. Empty Pallet Transfer: When a pallet in the loading silo 3 is emptied, the transfer mechanism 11 will grab the empty pallet and transfer it to the unloading silo 4 for reuse.

[0055] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
