[0003] During the milling process of the dial lens, milling fluid is usually sprayed for cooling and lubrication, and to take away the heat and debris generated by the milling. When the existing milling machines fix the dial lens, in order to prevent the clamp from scratching and wearing the lens, some milling machines use suction cups to fix the lens. During the milling process, the milling fluid mixed with debris splashes onto the suction cup used to fix the lens. After the lens is removed, the remaining milling fluid and debris flow to the suction cup mouth. When the lens is adsorbed and fixed next time, the flowing milling fluid mixed with debris is sucked into the air pump, causing the air pump to be damaged due to the inhalation of the milling fluid and debris, greatly reducing the service life of the equipment.

[0004] Furthermore, when the milling wheel of the milling machine is milling the edge of the lens, some debris adheres to the inner annular surface of the milling wheel. As the milling wheel rotates vertically, the adhered debris moves along the inner annular surface of the milling wheel to the contact position between the lens and the milling wheel, causing the milling wheel to mill the dial lens mixed with lens debris, resulting in excessive wear of the lens.

[0023] Furthermore, in order to move the debris accumulated on the inner wall of the milling wheel 202 away from the lens and be discharged through the chip removal hole 20201, and prevent the adhered debris from moving to the contact position between the milling wheel 202 and the lens, thereby avoiding excessive wear of the lens, the milling wheel 202 is configured to be a frustum.

[0024] It also includes a blocking block 205 ; the blocking block 205 is fixedly connected to the milling table 1 .

[0025] The cleaning component includes a liquid inlet pipe 301 and a liquid outlet pipe 302; the liquid inlet pipe 301 is fixedly connected to the milling table 1; the liquid inlet pipe 301 is connected to an external water pump; the liquid inlet pipe 301 is connected to the liquid collecting chamber 3001; the liquid outlet pipe 302 is fixedly connected to the milling table 1; the liquid outlet pipe 302 is connected to the inside of the cleaning cover 3.

[0026] Furthermore, in order to prevent the liquid and debris on the outside of the cleaning hood 3 from flowing downward to the bottom of the fixed tube 104, to prevent the air pump connected to the air pipe 106 from being damaged due to the inhalation of liquid and debris, and at the same time to make the liquid dripping from the bottom of the cleaning hood 3 drip quickly and reduce the dripping of milling fluid and debris, the bottom of the cleaning hood 3 is arranged to be inclined with the inside higher and the outside lower.

[0027] Furthermore, in order to guide the dripping liquid and debris away from the lens grinding area at the bottom of the cleaning cover 3 to prevent the debris from falling to the lens grinding area and affecting the lens grinding, the bottom of the cleaning cover 3 is set to be inclined with the left side lower and the right side higher.

[0028] It also includes rubber bumps 4; a plurality of rubber bumps 4 in an annular array are fixedly connected to the inner wall of the cleaning cover 3; a plurality of one-way air outlets 2002 in an annular array are opened on the elastic airbag 2; a one-way air inlet 2003 is opened on the upper side of the elastic airbag 2.

[0029] The present invention collects the debris splashed during milling by the elastic airbag 2, so that the debris adheres to the outer side of the elastic airbag 2, thereby solving the problem that the milling fluid mixed with the debris splashes onto the fixing tube 104, and the dripping milling fluid mixed with the debris is sucked into the air pump through the air pipe 106 when the lens is adsorbed and fixed next time, causing the air pump to be damaged due to the inhalation of liquid and debris. The specific process is as follows: When the edge of the dial lens is milled, the dial lens is first transferred to the lower side of the fixing tube 104 through the external feeding mechanism, and then the external air pump is controlled to evacuate the connecting ring 105 through the air pipe 106, so that the connecting ring 105 sucks the inside of the fixing tube 104, and then the dial lens is adsorbed and fixed to the lower side of the fixing tube 104. After the dial lens is fixed, the motor 201 is controlled to drive the milling wheel 202 to rotate, and at the same time, the spray pipe 203 sprays the milling liquid toward the milling wheel 202, and the drain pipe 204 sucks the sprayed milling liquid for reuse, and then the driving part 101 is controlled to drive the fixing tube 104 and related parts to move downward from the cleaning cover 3, so that the fixing tube 104 drives the dial lens to descend to It contacts the rotating milling wheel 202 and controls the DD motor 103 to drive the fixed tube 104 to rotate slowly, so as to mill the edge of the lens. During this process, the rotation of the milling wheel 202 will splash the milling fluid and the debris milled from the lens on the milling table 1, and the debris splashed onto the top of the lens during milling is collected by the elastic airbag 2, so that the debris adheres to the outside of the elastic airbag 2 and the soft film 2001, reducing the milling fluid that flows to the lower side of the fixed tube 104 after milling. When the lens is adsorbed and fixed next time, the milling fluid and debris sucked into the air pump by the air pipe 106 on the lower side of the fixed tube 104 are reduced, thereby avoiding the air pump connected to the air pipe 106 from being damaged due to the inhalation of milling fluid and debris.

[0030] When the milling wheel 202 rotates to mill the edge of the lens, the milling wheel 202 is set to a truncated cone shape, so that the debris adhered to the inner wall of the milling wheel 202 moves in the direction away from the lens under the action of centrifugal force when the milling wheel 202 rotates, and is discharged through the chip removal hole 20201, preventing the adhered debris from moving to the contact position between the milling wheel 202 and the lens, thereby avoiding excessive wear of the lens. At the same time, the chip removal hole 20201 rotated to the upward direction is blocked by the blocking block 205, so that the debris adhered to the inner wall of the milling wheel 202 can only be discharged through the chip removal hole 20201 rotated to the downward direction, thereby reducing the debris splashing in the milling table 1, which helps to reduce the subsequent cleaning work of the milling table 1.

[0031] When the edge of the lens is milled, the control driving part 101 drives the fixing tube 104 and related parts to rise, so that the fixing tube 104 drives the dial lens to rise and separate from the milling wheel 202. The fixing tube 104 drives the elastic airbag 2 to rise together while rising. In this process, the upper side of the elastic airbag 2 is blocked and limited by the rubber protrusion 4, so that the elastic airbag 2 is squeezed and contracted upward by the fixing tube 104, and the compressed gas inside the elastic airbag 2 is blown toward the milling fluid and debris hanging on the lower side of the cleaning cover 3 through the one-way air outlet 2002, so as to blow away the milling fluid and debris hanging on the lower side of the cleaning cover 3, and prevent the milling fluid and debris hanging on the lower side of the cleaning cover 3 from flowing to the lower side of the fixing tube 104 after the lens is removed, so as to avoid contact with the air pipe 10 6 is damaged due to the inhalation of milling fluid and debris. As the fixed tube 104 continues to squeeze the elastic airbag 2 upward, the elastic airbag 2 passes over the rubber bump 4 and rebounds upward under the action of its own elastic force to reset. At the same time, the outside air is sucked into the elastic airbag 2 through the one-way air inlet 2003. At this time, the driving member 101 drives the fixed tube 104 and the lens to rise to the lower opening of the cleaning cover 3, and the fixed tube 104 blocks the lower opening of the cleaning cover 3, separating the elastic airbag 2 from the lower side of the fixed tube 104, preventing the milling fluid and debris on the elastic airbag 2 from flowing downward to the lower side of the fixed tube 104, and avoiding the air pump connected to the air pipe 106 from being damaged due to the inhalation of milling fluid and debris.

[0032] When the fixed tube 104 drives the lens to rise to block the lower opening of the cleaning cover 3, each layer of soft film 2001 is located at the lower side of the corresponding liquid outlet hole 3002. The milled lens is removed from the fixed tube 104 through the external feeding mechanism, and the lens to be milled is replaced. During the lens replacement process, the external water pump is controlled to pump water from the liquid inlet pipe 301 to the liquid collecting chamber 3001, and then the liquid collecting chamber 3001 sprays water from each liquid outlet hole 3002 toward the corresponding soft film 2001, so as to wash away the milling liquid and debris adhered to the outer side of the elastic airbag 2. The milling fluid and debris flushed down are discharged from the liquid outlet pipe 302 to the outside of the cleaning cover 3 to the external collection device, so as to clean the milling fluid and debris adhering to the outside of the elastic airbag 2, prevent the debris from constantly accumulating on the outside of the elastic airbag 2, and avoid affecting the normal milling work of the lens. After the cleaning work of the elastic airbag 2 is completed, the lens on the lower side of the fixed tube 104 is replaced, and the control driving part 101 drives the fixed tube 104 and related parts to move downward from the cleaning cover 3, and prepares to mill the edge of the dial lens again.

[0033] Example 2 On the basis of Example 1, Figure 2 and Figure 5 As shown, it also includes a limit rod 401 and a guide piece 402; a plurality of storage grooves 3003 in a circular array are provided on the inner wall of the cleaning cover 3; each storage groove 3003 is rotatably connected to a limit rod 401 through a torsion spring; each limit rod 401 is provided with a plurality of limit parts 40101; each limit part 40101 is initially in a horizontally inclined state in the cleaning cover 3; two guide pieces 402 which are symmetrical up and down are fixedly connected to the upper outer side of the elastic airbag 2.

[0034] When the driving member 101 drives the fixed tube 104 and related parts to rise and prepares to replace the lens to be milled, the elastic airbag 2 drives the guide piece 402 to contact the limit part 40101 after passing over the rubber protrusion 4, and the lowermost limit part 40101 on the limit rod 401 is squeezed toward the inner wall of the cleaning cover 3 through the guide piece 402 located on the upper side, so that the limit rod 401 is rotated and stored in the storage groove 3003, and the torsion spring is compressed at the same time. As the fixed tube 104 drives the elastic airbag 2 to continue to rise, when the guide piece 402 located on the upper side rises and passes over all the limit parts in sequence, After 40101, the limiting rod 401 drives the limiting part 40101 to pop out from the storage groove 3003 under the elastic force of the torsion spring. At this time, the lower part of the fixed tube 104 blocks the lower opening of the cleaning cover 3. At this time, each layer of soft film 2001 is in contact with the lower side of the corresponding limiting part 40101, and the soft film 2001 is squeezed downward by the limiting part 40101, so that the soft film 2001 is deformed and bent downward, which is convenient for the water flow sprayed from the liquid outlet 3002 to clean the debris mixed in the soft film 2001, which is beneficial to enhance the cleaning effect of the soft film 2001.

[0035] When the cleaning work of the elastic airbag 2 is completed, the driving member 101 drives the fixed tube 104 and the elastic airbag 2 to descend, and then drives the guide piece 402 to descend, and the limiting part 40101 on the limiting rod 401 is squeezed toward the inner wall of the cleaning cover 3 through the guide piece 402 located on the lower side, so that the limiting rod 401 is rotated and stored in the storage groove 3003, and the torsion spring is compressed at the same time. When the guide piece 402 located on the lower side descends and passes over all the limiting parts 40101, the limiting rod 401 drives the limiting part 40101 to pop out from the storage groove 3003 under the elastic force of the torsion spring to reset, preparing for the next cleaning work.
