Description

A processing device for lens ring cutting

Technical Field

The invention belongs to the technical field of automated processing equipment, and in particular relates to a processing equipment for lens ring cutting.

Background Art

Fixtures are widely used in the CNC machine tool industry and are an indispensable and important component in CNC processing. In the CNC processing of traditional resin lenses, the lenses are mainly supported and positioned by the positioning seat of the fixture, and then the lens is clamped and fixed by the clamping arm mechanism. Therefore, when the lens is circularly cut, the tool or the clamping arm needs to interpolate the X/Y axis so that the tool and the clamping arm can avoid each other. In addition, after the lens is processed, the chips need to be collected manually.

Summary of the invention

The object of the present invention is to provide a processing device for lens ring cutting to solve the technical defects described in the background technology.

The processing equipment for lens ring cutting comprises a machine base, which is provided with a lower module and an upper module. The lower module comprises a DD motor and a lower cover installed on the machine base. The lower cover is connected to a negative pressure air outlet duct. The inner shaft of the lower cover is connected to a turntable seat. The turntable seat is transmission-connected to the DD motor. The turntable seat is used to place the lens to be ring cut and the outer periphery of the lens extends to the outside of the outer periphery of the turntable seat. The turntable seat is provided with a vacuum suction port for adsorbing and fixing the lens. The upper module comprises a lifting module arranged on the machine base. The lifting module drives a lifting frame. The lifting frame is provided with an upper cover. The upper cover is provided with a tool that extends into the upper cover and contacts the outer periphery of the lens. The inner shaft of the upper cover is connected with a pressure cover, and the pressure cover is provided with a positive pressure air inlet hole. When the lifting module drives the lifting frame to descend, the upper cover is covered on the lower cover to form a sealed cavity, and the negative pressure air outlet is connected with the sealed cavity to maintain a negative pressure environment in the sealed cavity. At the same time, the pressure cover is pressed down onto the lens to form a positive pressure inner cavity, and the positive pressure air inlet hole is connected with the positive pressure inner cavity to maintain a positive pressure environment in the positive pressure inner cavity and use the positive pressure environment to push the lens tightly onto the turntable seat to further fix the lens. An air relief gap is provided at the contact between the pressure cover and the lens. The air relief gap is used to blow away the chips around the lens, and the air outlet of the air relief gap is less than the air intake of the positive pressure air inlet hole.

According to the technical solution, the present invention can achieve the following beneficial effects:

1. When cutting the lens in a circular manner, the center of the lens can be fixed by the turntable and the pressure cover. At the same time, the turntable is driven by the DD motor to drive the lens to rotate. Therefore, the tool only needs to enter the sealed cavity from the inlet and keep in contact with the outer diameter of the lens to perform circular cutting. There is no need to avoid any objects through repeated interpolation movements of the X/Y axis;

2. When cutting the lens, the tool can continuously contact the outer diameter of the rotating lens, so the tool does not need to move and rotate repeatedly, thereby improving the cutting accuracy and efficiency of the lens;

3. When the lens is circularly cut, the lens can be pushed tightly onto the turntable by the air pressure of the positive pressure inner cavity, so that the lens can be more firmly fixed on the turntable;

4. Since the lower cover is provided with a negative pressure air outlet duct which can be connected with the sealing cavity, the negative pressure air outlet duct can automatically absorb and collect the cuttings generated when the lens is cut, thereby improving the convenience of lens cutting and avoiding the accumulation of cuttings which may affect the cutting quality of the lens. In addition, when the lens is taken out after cutting, the upper surface of the lens is in a clean state and the lens surface is prevented from being contaminated by dust.

5. Since there is an air vent at the contact point between the gland and the lens, the air vent can blow out the chips around the lens when the lens is ring cut, thus avoiding the chips accumulating on the upper surface of the lens and affecting the ring cutting quality of the lens;

6. Since the lifting frame is driven by the lifting module to drive the upper cover to cover the lower cover and the pressing cover to press down on the lens, the lens can be automatically fixed before the lens is ring-cut, thereby improving the convenience and efficiency of ring-cutting;

7. When cutting the lens, the cutting is completed in a sealed chamber to prevent the chips generated during the cutting from flying outward, so that the cutting of the lens can be completed in a dust-free workshop;

8. Since there is an air release gap between the pressure cover and the lens, that is, the pressure cover may not contact the lens, therefore, even if the pressure cover does not contact the lens, it can be pushed onto the turntable seat. At the same time, during the lens ring cutting process, even if the pressure cover cannot rotate, the lens can be fixed;

9. When the lens is circularly cut, since the sealed chamber is in a negative pressure state, when the upper cover and the lower cover are opened, the chips in the sealed chamber will not fly out.

In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

In some embodiments, the upper cover is provided with an upper air inlet slit located above the pressure cover, and the top of the upper cover is provided with a guide arc surface located below the upper air inlet slit for guiding the airflow to the outside of the lens;

According to the technical solution, the present invention can further achieve the following beneficial effects:

1. When cutting the lens in a circular manner, the guide arc surface can guide the airflow entering from the air inlet slit to the outside of the lens to further blow out the chips on and around the lens, thereby better avoiding the accumulation of chips on the upper surface of the lens;

2. Since the guide arc surface is used to guide the airflow from the upper air inlet slit to the periphery of the lens, the airflow from the upper air inlet slit entering the sealed cavity can collide with and disturb the airflow from the air leakage slit entering the sealed cavity, thereby causing the chips in the sealed cavity to fly irregularly, so that the negative pressure air outlet duct can better absorb and collect the chips, while also preventing the air leakage slit from blowing the chips to a corner of the sealed cavity for accumulation.

In some embodiments, the lower cover is provided with a lower air inlet slit located below the turntable seat, and the airflow entering the sealed cavity through the lower air inlet slit is used to blow out the chips below the lens, to blow up the chips that fall to the bottom of the lower cover, and to impact and disturb the airflow entering the sealed cavity through the air release slit and the airflow entering the sealed cavity through the upper air inlet slit;

According to the technical solution, the present invention can further achieve the following beneficial effects:

1. The airflow entering the sealed cavity from the lower air inlet slit can blow out the chips on the lower surface of the lens, so as to better ensure that the lens surface is in a clean state and avoid dust contamination when the lens is taken out after ring cutting.

2. The airflow entering the sealed chamber from the lower air inlet slit can blow up the chips at the bottom of the sealed chamber, thereby preventing the chips from accumulating at the bottom of the sealed chamber;

3. Since the airflow entering the sealed chamber from the lower air inlet slit can impact and disrupt the airflow entering the sealed chamber from the air vent slit and the airflow entering the sealed chamber from the upper air inlet slit, the chips in the sealed chamber can further fly irregularly, so that the negative pressure air outlet duct can absorb and collect the chips more stably.

In some embodiments, the upper cover is tilted to provide an oblique air outlet communicating with the sealed cavity;

According to the technical solution, the airflow entering the sealed cavity through the oblique air port is further impacted and disturbed by the airflow entering the sealed cavity through the air vent and the airflow entering the sealed cavity through the upper air inlet slit, so that the chips in the sealed cavity can further fly more irregularly.

In some embodiments, the inner wall of the sealed cavity is an arc surface surrounding the lens, so that when the lens rotates, it can drive the air in the sealed cavity to rotate, thereby driving the flying chips to move to the negative pressure air outlet duct, so that the negative pressure air outlet duct can absorb and collect the chips more stably.

In some embodiments, the lower air inlet slit and the oblique air outlet are both provided with an air pipe joint for controlling intermittent air intake; according to the technical solution, the air supply device can intermittently input irregular airflow and air pressure to the lower air inlet slit and the oblique air outlet through the air pipe joint, so that the chips in the sealed cavity can further fly more irregularly.

In some embodiments, the lifting frame is installed with a shaft sleeve, the upper cover is provided with a guide column passing through the shaft sleeve, the top end of the guide column is mounted on the shaft sleeve, and a spring is provided between the lifting frame and the upper cover;

According to the technical solution, the present invention can further achieve the following beneficial effects:

1. When the upper cover is closed on the lower cover, the upper cover can be pushed tightly against the lower cover by the spring to ensure the sealing of the sealing cavity;

2. The spring can buffer the impact force generated when the upper cover and the lower cover come into contact, thereby protecting the upper cover and the lower cover.

In some embodiments, the machine base is installed with a slide rail and a shift cylinder, a slider seat drivingly connected to the shift cylinder slides on the slide rail, the upper mold assembly is installed on the slider seat, and the shift cylinder is used to drive the upper cover to move away from and to just above the lower cover;

According to the technical solution, after the lens is circularly cut or before the lens is circularly cut, the shift cylinder drives the slider seat to move, and the slider seat drives the upper mold assembly to move, so that the shift cylinder is used to drive the upper cover to move away from directly above the lower cover, thereby facilitating the robot or operator to place the lens on the turntable seat or take it out from the turntable seat.

In some embodiments, a positioning buffer is provided at one end of the slide rail next to the lower cover;

According to the technical solution, after the shift cylinder drives the slider seat to drive the upper cover of the upper mold assembly to move to just above the lower cover, the positioning buffer can position the slider seat so that the upper cover can be accurately aligned with the lower cover.

DETAILED DESCRIPTION

In order to make the objectives, technical solutions and advantages of the present invention more clear, this specific implementation method further describes the present invention in detail with reference to the accompanying drawings.

As shown in Figures 1 to 4, this specific embodiment provides a processing equipment for lens ring cutting, which includes a machine base 1, and the machine base 1 is provided with a lower module and an upper module. The lower module includes a DD motor 21 and a lower cover 22 installed on the machine base 1. The lower cover 22 is connected to a negative pressure air outlet duct 23. The inner shaft of the lower cover 22 is connected to a turntable seat 24. The turntable seat 24 is transmission-connected to the DD motor 21. The turntable seat 24 is used to place the lens 7 to be ring cut, and the outer periphery of the lens 7 extends to the outside of the outer periphery of the turntable seat 24. The turntable seat 24 is provided with a vacuum suction port 241 for adsorbing and fixing the lens 7. The upper module includes a lifting module 31 arranged on the machine base 1. The lifting module 31 drives a lifting frame 32. The lifting frame 32 is provided with an upper cover 33. The upper cover 33 is provided with a tool 5 that extends into the upper cover 33 and contacts the outside of the lens 7. The upper cover 33 is connected to the inner shaft of the upper cover 33 with a pressure cover 35, and the pressure cover 35 is provided with a positive pressure air inlet hole 351. When the lifting module 31 drives the lifting frame 32 to descend, the upper cover 33 is covered on the lower cover 22 to form a sealed chamber 4, and the negative pressure air outlet 23 is connected with the sealed chamber 4, so that the negative pressure environment is maintained in the sealed chamber 4. At the same time, the pressure cover 35 is pressed down onto the lens 7 to form a positive pressure inner chamber 352, and the positive pressure air inlet hole 351 is connected with the positive pressure inner chamber 352, so that the positive pressure inner chamber 352 maintains a positive pressure environment and uses the positive pressure environment to push the lens 7 tightly onto the turntable seat 24 to further fix the lens 7. An air relief gap 353 is provided at the contact point between the pressure cover 35 and the lens 7. The air relief gap 353 is used to blow away the chips around the lens 7, and the air outlet of the air relief gap 353 is less than the air intake of the positive pressure air inlet hole 351. In addition, the vacuum suction port 241 and the positive pressure air inlet hole 351 may be provided with a rotating air pipe joint 6 .

When the lens 7 is cut in a circular manner, the center of the lens 7 can be fixed by the turntable seat 24 and the pressure cover 35. At the same time, the turntable seat 24 is driven by the DD motor 21 to drive the lens 7 to rotate. Therefore, the tool 5 only needs to enter the sealed cavity 4 from the cutting port 34 and keep in contact with the outer diameter of the lens 7 to perform circular cutting. There is no need to avoid any objects through repeated interpolation movements of the X/Y axis. In addition, since the tool 5 can continuously keep in contact with the outer diameter of the rotating lens 7, the tool 5 does not need to move and rotate repeatedly, thereby improving the circular cutting accuracy and efficiency of the lens 7. In addition, since the lens 7 can be pushed tightly onto the turntable seat 24 by the air pressure of the positive pressure inner cavity 352, the lens 7 can be more firmly fixed on the turntable seat 24.

Since the lower cover 22 is provided with a negative pressure air outlet duct 23 which can communicate with the sealing chamber 4, the negative pressure air outlet duct 23 can automatically absorb and collect the chips generated when the lens 7 is cut in an annular manner, thereby improving the convenience of the lens 7 in annular cutting, and at the same time, it can also prevent the accumulation of chips and affect the quality of the lens 7 in annular cutting. In addition, when the lens 7 is taken out after the annular cutting, the upper surface of the lens 7 is in a clean state and the surface of the lens 7 is prevented from being contaminated by dust. At the same time, since the contact between the pressure cover 35 and the lens 7 is provided with an air release slit 353, when the lens 7 is cut in an annular manner, the air release slit 353 can be used to release the dust on the upper surface of the lens 7. The chips around the lens 7 can be blown out to the outside, so as to avoid the chips accumulating on the upper surface of the lens 7 and affecting the ring cutting quality of the lens 7; in addition, since the lifting frame 32 is driven by the lifting module 31 to drive the upper cover 33 to cover the lower cover 22 and the pressure cover 35 to be pressed down onto the lens 7, the lens 7 can be automatically fixed before the ring cutting of the lens 7, so as to improve the convenience and efficiency of the ring cutting; in addition, since the sealing chamber 4 is in a negative pressure state, when the upper cover 33 and the lower cover 22 are opened, the chips in the sealing chamber 4 will not fly out.

When the lens 7 is circularly cut, since the lens 7 is circularly cut in the sealed cavity 4, the chips generated during the circular cutting of the lens 7 are prevented from flying outward, so that the circular cutting of the lens 7 can be completed in a dust-free workshop; at the same time, since an air venting gap 353 is provided between the pressure cover 35 and the lens 7, that is, the pressure cover 35 may not contact the lens 7, therefore, even if the pressure cover 35 does not contact the lens 7, it can be pushed tightly onto the turntable seat 24, and at the same time, during the circular cutting process of the lens 7, even if the pressure cover 35 cannot rotate by itself, it can still fix the lens 7.

In some embodiments, the upper cover 33 is provided with an upper air inlet slit 331 located above the pressure cover 35 , and the top of the upper cover 33 is provided with a guide arc surface 332 located below the upper air inlet slit 331 for guiding the airflow to the outside of the lens 7 .

When the lens 7 is cut in an annular shape, the guide arc surface 332 can guide the airflow entering from the upper air inlet slit 331 to the outside of the lens 7, so as to further blow out the chips on and around the lens 7, thereby better avoiding the chips from accumulating on the upper surface of the lens 7; because the guide arc surface 332 is used to guide the airflow from the upper air inlet slit 331 to the outside of the lens 7, the airflow entering the sealed cavity 4 from the upper air inlet slit 331 can collide with and disturb the airflow entering the sealed cavity 4 from the air discharge slit 353, thereby causing the chips in the sealed cavity 4 to fly more irregularly, so that the negative pressure air outlet duct 23 can better absorb and collect the chips, while also preventing the air discharge slit 353 from blowing the chips to a corner of the sealed cavity 4 for accumulation.

In some embodiments, the lower cover 22 is provided with a lower air inlet slit 221 located below the turntable seat 24. The airflow entering the sealed cavity 4 through the lower air inlet slit 221 is used to blow out the chips below the lens 7, to blow up the chips that have fallen to the bottom of the lower cover 22, and to impact and disrupt the airflow entering the sealed cavity 4 through the air vent slit 353 and the airflow entering the sealed cavity 4 through the upper air inlet slit 331.

The airflow entering the sealed cavity 4 through the lower air inlet slit 221 can blow out the chips located on the lower surface of the lens 7, so as to better ensure that the surface of the lens 7 is in a clean state and prevent the surface of the lens 7 from being contaminated by dust when the lens 7 is taken out after the ring cutting is completed; in addition, the airflow entering the sealed cavity 4 through the lower air inlet slit 221 can blow up the chips at the bottom of the sealed cavity 4, so as to prevent the chips from accumulating at the bottom of the sealed cavity 4; because the airflow entering the sealed cavity 4 through the lower air inlet slit 221 can collide and disrupt the airflow entering the sealed cavity 4 through the air vent slit 353 and the airflow entering the sealed cavity 4 through the upper air inlet slit 331, the chips in the sealed cavity 4 can further fly irregularly, so that the negative pressure air outlet duct 23 can more stably absorb and collect the chips.

The upper cover 33 is tilted to provide an oblique air outlet 356 connected to the sealed cavity 4, so that the airflow entering the sealed cavity 4 through the oblique air outlet 356 can further impact and disrupt the airflow entering the sealed cavity 4 through the air vent 353 and the airflow entering the sealed cavity 4 through the upper air inlet slit 331, thereby making the chips in the sealed cavity 4 fly more irregularly.

In some embodiments, the inner wall of the sealed cavity 4 is an inner arc surface 41 surrounding the lens 7, so that when the lens 7 rotates, it can drive the air in the sealed cavity 4 to rotate, so that the flying chips move to the negative pressure air outlet duct 23, so that the chips in the sealed cavity 4 can further fly more irregularly, so that the negative pressure air outlet duct 23 can more stably absorb and collect the chips.

In some embodiments, the lower air inlet slit 221 and the oblique air outlet 356 are both provided with an air pipe joint 6 for controlling intermittent air supply, so that the air supply device can intermittently input irregular airflow and air pressure to the lower air inlet slit 221 and the oblique air outlet 356 through the air pipe joint 6, thereby causing the chips in the sealed cavity 4 to further fly more irregularly.

In some embodiments, the lifting frame 32 is installed with a shaft sleeve 321 , the upper cover 33 is provided with a guide column 322 passing through the shaft sleeve 321 , the top end of the guide column 322 is mounted on the shaft sleeve 321 , and a spring 323 is provided between the lifting frame 32 and the upper cover 33 .

When the upper cover 33 is closed on the lower cover 22, the spring 323 can push the upper cover 33 tightly against the lower cover 22 to ensure the sealing of the sealing cavity 4; at the same time, the spring 323 can buffer the impact force generated when the upper cover 33 and the lower cover 22 contact at the moment, thereby protecting the upper cover 33 and the lower cover 22.

In some embodiments, the machine base 1 is installed with a slide rail 11 and a shift cylinder 12, a slider seat 13 sliding on the slide rail 11 and connected to the shift cylinder 12, the upper mold assembly is installed on the slider seat 13, and the shift cylinder 12 is used to drive the upper cover 33 to move away and to the top of the lower cover 22.

After the lens 7 is circularly cut or before the lens 7 is circularly cut, the shift cylinder 12 drives the slider seat 13 to move, and the slider seat 13 drives the upper mold assembly to move, so that the shift cylinder 12 is used to drive the upper cover 33 to move away from directly above the lower cover 22, thereby facilitating the robot or operator to place the lens 7 on the turntable seat 24 or take it out from the turntable seat 24.

In some embodiments, a positioning buffer 14 is provided at one end of the slide rail 11 and is located next to the lower cover 22; after the shift cylinder 12 drives the slider seat 13 to drive the upper cover 33 of the upper mold assembly to move to just above the lower cover 22, the positioning buffer 14 can position the slider seat 13, so that the upper cover 33 can be accurately aligned with the lower cover 22.

In some embodiments, the lifting module 31 is a lifting cylinder installed on the slider seat 13 and used to drive the lifting frame 32 to move up and down; so that the lifting module 31 can drive the upper cover 33 to cover the lower cover 22 quickly and stably.

In order to further illustrate the processing equipment for lens ring cutting described in this specific embodiment, the following examples are listed.

The turntable seat 24 is used to place the lens 7 to be cut and the outer periphery of the lens 7 extends to the outside of the outer periphery of the turntable seat 24. The turntable seat 24 is provided with a vacuum suction port 241 for adsorbing and fixing the lens 7. The lower cover 22 is provided with a lower air inlet slit 221 located below the turntable seat 24.

The machine base 1 is equipped with a slide rail 11 and a shift cylinder 12. A slider seat 13 that is transmission-connected to the shift cylinder 12 slides on the slide rail 11. A positioning buffer 14 located next to the lower cover 22 is provided at one end of the slide rail 11. The positioning buffer 14 is used to contact the slider seat 13. A lifting module 31 is installed on the slider seat 13. The lifting module 31 can be a lifting cylinder, a screw module or a hydraulic module, etc. The lifting module 31 drives a lifting frame 32. The lifting frame 32 is equipped with a shaft sleeve 321. A guide column 322 that can slide inside the shaft sleeve 321 passes through the shaft sleeve 321. The top of the guide column 322 can be mounted on the top of the shaft sleeve 321. The bottom end of the guide column 322 is fixed with an upper cover 33. A spring 323 is provided between the lifting frame 32 and the upper cover 33. The upper cover 33 is provided with a knife inlet 34 for the cutter 5 to extend into the upper cover 33 and contact the outer periphery of the lens 7. The upper cover 33 is internally axially connected with a pressure cover 35, and the pressure cover 35 is provided with a positive pressure air inlet hole 351.

When the lifting module 31 drives the lifting frame 32 to descend, the upper cover 33 is covered on the lower cover 22 to form a sealed chamber 4, and the negative pressure outlet duct 23 is connected with the sealed chamber 4, so that the negative pressure environment is maintained in the sealed chamber 4. At the same time, the pressure cover 35 is pressed down onto the lens 7 to form a positive pressure inner chamber 352, and the positive pressure air inlet hole 351 is connected with the positive pressure inner chamber 352, so that the positive pressure inner chamber 352 maintains a positive pressure environment and uses the positive pressure environment to push the lens 7 tightly onto the turntable seat 24 to further fix the lens 7. The contact between the pressure cover 35 and the lens 7 is provided with an air release slit 353, and the air release slit 353 is used to blow away the chips around the lens 7. The upper cover 33 is provided with an upper air inlet slit 331 located above the pressure cover 35, and the top of the upper cover 33 is provided with a guide arc surface 332 located below the upper air inlet slit 331 for guiding the airflow to the outside of the lens 7. The airflow entering the sealed cavity 4 through the lower air inlet slit 221 is used to blow up the chips under the lens 7, to blow up the chips that fall to the bottom of the lower cover 22, and to impact and disturb the airflow entering the sealed cavity 4 through the air release slit 353 and the airflow entering the sealed cavity 4 through the upper air inlet slit 331. The upper cover 33 is inclined to be provided with an oblique air port 356 that is connected to the sealed cavity 4. The inner wall of the sealed cavity 4 is an inner cavity arc surface 41 that surrounds the lens 7, so that the rotation of the lens 7 can drive the air in the sealed cavity 4 to rotate. Both the lower air inlet slit 221 and the oblique air port 356 are provided with an air pipe joint 6 for controlling intermittent air inlet.

The following are the working steps of the processing equipment described in this embodiment:

1. The shift cylinder 12 drives the slider seat 13 to move, and the slider seat 13 drives the upper mold assembly to move, so that the upper cover 33 of the upper mold assembly moves away from the top of the lower cover 22. At this time, the operator or the manipulator places the lens 7 on the turntable seat 24, and then the vacuum suction port 241 adsorbs and fixes the lens 7;

2. After that, the shift cylinder 12 drives the slider seat 13 to move in the reverse direction, and the slider seat 13 drives the upper die set to move in the reverse direction until the slider seat 13 hits the positioning buffer 14. At this time, the upper cover 33 is aligned with the lower cover 22;

3. Thereafter, the lifting module 31 drives the lifting frame 32 to descend, and the upper cover 33 covers the lower cover 22 to form a sealed chamber 4. At this time, the negative pressure outlet duct 23 is connected with the sealed chamber 4, so that the sealed chamber 4 maintains a negative pressure environment. The pressure cover 35 is pressed down onto the lens 7 to form a positive pressure inner chamber 352. The positive pressure air inlet hole 351 is connected with the positive pressure inner chamber 352, so that the positive pressure inner chamber 352 maintains a positive pressure environment and uses the positive pressure environment to push the lens 7 tightly onto the turntable seat 24 to further fix the lens 7.

4. Thereafter, the DD motor 21 drives the turntable 24 to rotate, and the turntable 24 drives the lens 7 to rotate. Subsequently, the tool 5 enters the sealed cavity 4 from the cutting opening 34 and keeps in contact with the outer diameter of the lens 7 to perform a circular cutting process on the lens 7.

5. During the ring cutting process of the lens 7, the air release slit 353 is used to blow the chips around the lens 7. At the same time, the guide arc surface 332 guides the airflow of the upper air inlet slit 331 to the lens 7 around the lens 7 to blow out the chips on and around the lens 7. The airflow of the upper air inlet slit 331 hits and disturbs the airflow entering the sealed cavity 4 through the air release slit 353. At the same time, the airflow entering the sealed cavity 4 through the lower air inlet slit 221 blows out the chips under the lens 7 around the lens 7, blows up the chips that fall to the bottom of the lower cover 22, hits and disturbs the airflow entering the sealed cavity 4 through the air release slit 353. The airflow in the sealed cavity 4 and the airflow entering the sealed cavity 4 from the upper air inlet slit 331, and at the same time, the airflow entering the sealed cavity 4 from the oblique air outlet 356 further impact and disturb the airflow entering the sealed cavity 4 from the air release slit 353 and the airflow entering the sealed cavity 4 from the upper air inlet slit 331. At this time, the chips in the sealed cavity 4 fly up and down irregularly. In addition, when the lens 7 rotates, it can drive the air in the sealed cavity 4 to rotate, so as to drive the flying chips to rotate, so that the flying chips move to the negative pressure outlet duct 23, and the negative pressure outlet duct absorbs and collects the flying chips.

6. After the circular cutting of the lens 7 is completed, the DD motor 21 stops driving the turntable seat 24 to rotate, the lifting module 31 drives the lifting frame 32 to rise and reset, the upper cover 33 and the lower cover 22 are opened, and the vacuum suction port 241 stops adsorbing and fixing the lens 7. Subsequently, the shift cylinder 12 drives the slider seat 13 to move, and the slider seat 13 drives the upper module to move, so that the upper cover 33 of the upper module moves away from directly above the lower cover 22. At this time, the operator or the robot takes out the lens 7 on the turntable seat 24.
