[0027] Angle adjustment mechanism 4: It is located in the middle of the upper surface of the support platform 2. The upper end of the angle adjustment mechanism 4 is fixedly connected to the storage tray 3. The storage tray 3 has evenly distributed strip grooves inside, and clamping plates 6 are slidably connected inside each strip groove. The angle adjustment mechanism 4 includes a motor 41, a steering shaft 42, a connecting cylinder 43, a steering seat 44, a guide rail 45, and a steering gear 46. The connecting cylinder 43 is fixedly connected to the middle of the upper surface of the support platform 2 through a support. The steering shaft 42 is rotatably connected inside the connecting cylinder 43. The steering gear 46 is fixedly connected to both the front and rear ends of the steering shaft 42. The guide rail 45 is symmetrically fixedly connected to the middle of the upper surface of the support platform 2. The upper end of each guide rail 45 is slidably connected to the steering seat 44. The upper end of each steering seat 44 is fixedly connected to the lower end of the storage tray 3. A gear ring is provided at the end away from the center of the support platform 2. The gear ring is meshed with the vertically adjacent steering gear 46. The motor 41 is located at the rear end of the upper surface of the support platform 2. The front end of the output shaft of the motor 41 is fixedly connected to the rear end of the steering shaft 42. The input end of the motor 41 is electrically connected to the output end of the PLC controller 16. When the motor 41 is running, the output shaft of the motor 41 rotates, which drives the steering shaft 42 to rotate, and then drives the front and rear steering gears 46 to rotate. The rotation of the steering gears 46 causes the vertically adjacent steering seats 44 to slide inside the vertically adjacent guide rails 45 through the vertically adjacent gear rings. The sliding of the steering seats 44 allows the horizontal angle of the tray 3 to be adjusted, thereby realizing the angle adjustment of the optical glass lens, and thus effectively meeting the different milling requirements of the optical glass lens.

The input end of motor 2 51 is electrically connected to the output end of PLC controller 16. When motor 2 51 is running, the output shaft of motor 2 51 rotates, which drives the rotating shaft 52 to rotate, which in turn drives the first driving helical gear to rotate, which in turn causes the driven helical gear 1 53 to rotate. The rotation of the driven helical gear 1 53 drives the horizontally adjacent screw 52 to rotate. The rotation of the screw 52 causes the clamping plates 6 to move towards the center of the placement tray 3 in the vertically adjacent strip grooves, thereby achieving stable clamping of the optical glass lens to be milled.

[0029] The slide groove is rotatably connected to a lead screw 9, the middle of which is threaded to a lifting plate 8. The upper end of each lead screw 9 is fixedly connected to a driven helical gear 12. The upper end of the bracket 7 is rotatably connected to a rotating shaft 10. Both ends of the rotating shaft 10 are fixedly connected to driving helical gears 13, which mesh with the vertically adjacent driven helical gears 12. A motor 11 is installed on the upper end of the left side surface of the bracket 7. The output shaft of the motor 11 is fixedly connected to the left end of the rotating shaft 10. The input end of the motor 11 is electrically connected to the output end of the PLC controller 16. When the motor 11 operates... The output shaft of 11 rotates, driving the rotating shaft 10 to rotate. The rotating shaft 10 rotates, driving the two driving helical gears 13 to rotate. The rotation of the driving helical gears 13 drives the vertically adjacent driven helical gears 12 to rotate. The rotation of the driven helical gears 12 drives the vertically adjacent lead screw 9 to rotate, causing the lifting plate 8 to move down. This, in turn, drives the grinding wheel 14 to move down through the milling shaft. At the same time, the PLC controller 16 enables the motor 15 to operate. The output shaft of the motor 15 rotates, driving the milling shaft to rotate, which in turn drives the grinding wheel 14 to rotate. When the grinding wheel 14 contacts the optical glass lens to be milled, the milling of the optical glass lens is achieved.

[0030] The working principle of the milling machine for optical glass lenses provided by this utility model is as follows: During operation, the operator first uses bolts to stably connect the evenly distributed mounting holes at the lower end of the support platform 2 with the threaded holes in the horizontal working area, thus achieving stable installation of the support platform 2, the worktable 1, and other mechanisms. After stable installation, the operator places the optical glass lens to be milled at the center of the upper surface of the upright placement tray 3. Then, the operator uses the PLC controller 16 to drive the second motor 51. The output shaft of the second motor 51 rotates, driving the rotating shaft 52 to rotate, which in turn drives the first driving helical gear to rotate, thereby causing the driven helical gear 53 to rotate as well. The rotation of gear 53 drives the adjacent horizontal screw 52 to rotate. The rotation of screw 52 causes the clamping plates 6 to move towards the center of the placement tray 3 within the adjacent vertical slots, thereby achieving stable clamping of the optical glass lens to be milled. Then, the PLC controller 16 shuts down motor 51 and starts motor 11. The output shaft of motor 11 rotates, driving the rotating shaft 10 to rotate. The rotating shaft 10 rotates, driving the two driving helical gears 13 to rotate. The rotation of driving helical gears 13 drives the adjacent vertical driven helical gear 12 to rotate. The rotation of driven helical gear 12 drives the adjacent vertical lead screw 9 to rotate. This causes the lifting plate 8 to move downwards, which in turn drives the grinding wheel 14 to move downwards via the milling shaft. Simultaneously, the PLC controller 16 activates motor 45, whose output shaft rotates to drive the milling shaft, which in turn drives the grinding wheel 14 to rotate. When the grinding wheel 14 contacts the optical glass lens to be milled, the optical glass lens is milled. At the same time, the PLC controller 16 shuts down motor 3 11 and activates motor 41. The output shaft of motor 41 rotates to drive the steering shaft 42, which in turn drives the two steering gears 46 to rotate. The rotation of the steering gears 46 causes the vertically adjacent steering seats 44 to rotate via vertically adjacent gear rings. All slide within the vertically adjacent guide rails 45. The sliding of the steering seat 44 allows the horizontal angle of the tray 3 to be adjusted, thereby achieving the angle adjustment of the optical glass lens and effectively meeting the different milling requirements of the optical glass lens. After milling is completed, the PLC controller 16 reverses the operation of motor 41, causing the tray 3 to return to the horizontal position. At the same time, it reverses the operation of motor 51, causing the clamping plates 6 to move away from the center of the tray 3 within the corresponding slots, ending the clamping of the optical glass lens. Simultaneously, the PLC controller 16 shuts down motor 415, waiting for the milling of the next optical glass lens.

[0031] It is worth noting that, in the above embodiments, motor 41 can be an SGM7J-04AFC6S servo motor, motor 51 and motor 11 can both be 5IK120A-AF motors, motor 15 can be a LIKO MOTOR57 two-phase stepper motor, and PLC controller 16 can be a DVP48EH programmable controller. The PLC controller 16 controls the operation of motor 41, motor 51, motor 11 and motor 15 using methods commonly used in the prior art.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
