[0045] The embodiment of the present application provides a lens polishing device for polishing a lens 60, see Figure 1 and Figure 2 The lens polishing equipment includes a polishing module 10, a cleaning module 20 and a transfer module 30.

[0046] The polishing module 10 includes a polishing mechanism 11 and a positioning mechanism 12. The polishing mechanism 11 includes a polishing drive device 111 and a polishing head 112. The polishing head 112 cooperates with the drive of the polishing drive device 111 to drive the polishing head 112 to move at least in a first direction and a second direction and rotate along the rotation axis of the first direction. The first direction and the second direction intersect. The positioning mechanism 12 includes a positioning drive device and a positioning suction head 121. The positioning suction head 121 and the polishing head 112 are arranged along the first direction. The positioning suction head 121 cooperates with the drive of the positioning drive device to drive the positioning suction head 121 to rotate along the rotation axis of the first direction. The positioning suction head 121 is used to adsorb the lens 60 along the first direction. The positioning suction head 121 and the polishing head 112 are used to clamp the lens 60 along the first direction.

[0047] The cleaning module 20 is used to clamp the lens 60 perpendicular to the first direction and spray a cleaning liquid onto the lens 60 .

[0048] The transfer module 30 is at least used for clamping the lens 60 perpendicular to the first direction and transferring the lens 60 from the positioning head 121 to the cleaning module 20 .

[0049] The polishing mechanism 11 is used to drive the polishing head 112 to move in space so that the polishing head 112 can contact the area on the lens 60 that needs to be polished, and drive the polishing head 112 to rotate so that the polishing head 112 and the lens 60 rub against each other to achieve the purpose of polishing the lens 60.

[0050] It should be noted that the polishing drive device 111 drives the polishing head 112 to move linearly in the first direction and the second direction respectively.

[0051] It can be understood that the rotating shaft of the polishing drive device 111 driving the polishing head 112 to rotate can pass through the polishing head 112 or be located outside the polishing head 112.

[0052] The positioning suction head 121 can generate an adsorption force to adsorb the lens 60 so that the lens 60 is fixed to the positioning suction head 121, thereby reducing the probability of the positioning mechanism 12 damaging the lens 60.

[0053] The positioning drive device drives the positioning suction head 121 to rotate so that the lens 60 rotates accordingly.

[0054] By driving the polishing head 112 itself to rotate and the lens 60 to rotate with the positioning suction head 121, it is beneficial to improve the polishing effect of the polishing head 112 on the lens 60, improve the polishing efficiency, and enable the polishing head 112 to come into contact with a larger range of surfaces of the lens 60.

[0055] The positioning suction head 121 and the polishing head 112 are arranged in the first direction, and the polishing head 112 can move in the first direction under the drive of the polishing drive device 111. By driving the positioning suction head 121 and the polishing head 112 to approach each other in the first direction, the lens 60 can be clamped between the positioning suction head 121 and the polishing head 112 in the first direction to fix the position of the lens 60; by driving the positioning suction head 121 and the polishing head 112 to move away from each other in the first direction, the polishing head 112 can be separated from the lens 60 so that the transfer module 30 can separate the lens 60 from the positioning suction head 121.

[0056] It can be understood that during the process of the polishing head 112 contacting the lens 60 in the first direction, the polishing drive device 111 can drive the polishing head 112 to move in the second direction while rotating, so that the polishing head 112 can move radially along the axis of rotation of the lens 60. In this way, in cooperation with the rotation of the lens 60 generated by the positioning suction head 121, the polishing head 112 can come into contact with all areas of one side surface of the lens 60 in the first direction. For example, the axis of rotation of the lens 60 passes through the geometric center of the lens 60, the second direction is the radial direction of the axis of rotation of the lens 60, and during the rotation of the lens 60 with the positioning suction head 121, the polishing head 112 is driven to move in the second direction and keep in contact with the lens 60. After completing the polishing operation on one side surface of the lens 60 in the first direction, the polishing head 112 can be located at the position of the axis of rotation of the lens 60.

[0057] The cleaning module 20 clamps the lens 60 perpendicular to the first direction, so that the cleaning module 20 can avoid contacting the polished surface of the lens 60 along the first direction, reducing the risk of damaging the surface of the polished lens 60.

[0058] The cleaning module 20 sprays a cleaning liquid onto the lens 60 to clean foreign matters such as grinding debris generated during the polishing process of the lens 60 by the polishing module 10, so as to improve the cleanliness of the surface of the lens 60.

[0059] The transfer module 30 clamps the lens 60 perpendicular to the first direction, so that the transfer module 30 can avoid contacting the polished surface of the lens 60 along the first direction, reducing the risk of damaging the surface of the polished lens 60.

[0060] The transfer module 30 transfers the polished lens 60 to the cleaning module 20 to clean the polished lens 60.

[0061] In the lens polishing equipment in the implementation of this application, through the mutual cooperation of the polishing module 10, the cleaning module 20 and the transfer module 30, it is beneficial to realize the automatic processing of lens polishing, improving the operation efficiency of lens polishing and the stability of product quality; by driving the rotation of the lens 60 by the positioning mechanism 12 and making the polishing head 112 move along the second direction by the polishing mechanism 11, it is beneficial to adapt to different sizes and types of lenses 60 when the size of the polishing head 112 is certain, and it is beneficial to expand the application range of the lens polishing equipment.

[0062] The lens polishing equipment simulates the manual polishing actions. The main technical actions in the original manual operation, such as turning over and pressing, are all completed by the lens polishing equipment, which is flexible and controllable. The main process parameters, such as the pressing force, the flow rate of the polishing liquid, and the rotation speed of the lens 60, can be precisely controlled, and the polishing quality is greatly improved. All parameters can be selected with one key on the operation interface without manual input and adjustment, reducing the probability of the equipment operator of the lens polishing equipment coming into contact with the polishing liquid.

[0063] In some embodiments, the first direction is the vertical direction.

[0064] In some embodiments, the first direction is perpendicular to the second direction.

[0065] The specific manner in which the positioning suction head 121 generates an adsorption force to adsorb the lens 60 is not limited. For example, the positioning suction head 121 is provided with a through vacuum channel, and a negative pressure can be generated in the vacuum channel relative to the external atmosphere. One end of the vacuum channel forms a vacuum suction port on the surface of the positioning suction head 121. The lens 60 can be covered on the vacuum suction port, and by generating a negative pressure in the vacuum channel, the lens 60 can be fixed to the positioning suction head 121; after releasing the negative pressure in the vacuum channel, the transfer module 30 can move the lens 60 away from the positioning suction head 121.

[0066] In some embodiments, referring to Figure 6 , the polishing driving device 111 includes a first driver 1111 and a first telescopic cylinder 1112. The first telescopic cylinder 1112 is arranged at the driving end of the first driver 1111 to drive the first telescopic cylinder 1112 to move along the first direction, and the polishing head 112 is drivingly engaged with the first telescopic cylinder 1112 to drive the polishing head 112 to move along the first direction.

[0067] That is to say, the first driver 1111 and the first telescopic cylinder 1112 jointly achieve the purpose of driving the polishing head 112 to expand and contract along the first direction. Among them, after the first telescopic cylinder 1112 drives the polishing head 112 to extend along the first direction until the polishing head 112 abuts against the lens 60 along the first direction, the lens 60 itself is used as the limit for the first telescopic cylinder 1112 to extend along the first direction.

[0068] In this way, using the lens 60 itself to limit the movement of the polishing head 112 along the first direction is beneficial to enabling the polishing head 112 to maintain contact with different types of lenses 60 with different dimensions along the first direction while keeping the dimension of the polishing head 112 along the first direction unchanged, which is beneficial to improving the adaptability of the lens polishing equipment to lenses 60 of different sizes and expanding the applicable range of the lens polishing equipment.

[0069] The specific type of the first driver 1111 is not limited, such as a telescopic cylinder, a telescopic electric cylinder, etc.

[0070] In some embodiments, the first telescopic cylinder 1112 is a low-friction cylinder and is equipped with a precision pressure regulating valve to make the pressure output by the first telescopic cylinder 1112 along the first direction uniform and reduce the risk of damaging the lens 60 by the polishing head 112 along the first direction.

[0071] In some embodiments, referring to Figure 6 , the polishing mechanism 11 further includes a universal joint 113. The universal joint 113 connects the polishing driving device 111 and the polishing head 112 to enable the polishing head 112 to swing perpendicular to the first direction.

[0072] In this way, it is beneficial to keep the polishing head 112 in contact with the lens 60 by the swing of the polishing head 112 when one side surface of the lens 60 along the first direction is non-planar, so as to improve the efficiency of the polishing operation.

[0073] In some embodiments, the polishing mechanism 11 further includes a rubber protective sleeve. The rubber protective sleeve is sleeved outside the universal joint 113 to reduce the adverse effects on the movement of the universal joint 113 caused by external foreign objects entering the universal joint 113.

[0074] In some embodiments, referring to Figure 6, the polishing module 10 further includes a spraying mechanism 13 for spraying polishing liquid onto at least one of the polishing head 112 and the lens 60.

[0075] In this way, the polishing liquid can penetrate into the contact area between the polishing head 112 and the lens 60, which is beneficial to improving the polishing effect and taking away part of the heat generated by the friction between the polishing head 112 and the lens 60.

[0076] The polishing liquid includes fine particles, and the friction between the particles and the lens 60 achieves the polishing effect. The specific material of the particles can be silica, alumina, etc.

[0077] In some embodiments, refer to Figure 1 , the polishing mechanism 11 further includes a first shield 114. The first shield 114 is drivingly engaged with the polishing driving device 111 to drive the first shield 114 to move along the first direction. The first shield 114 is provided with a first protection space, and the polishing head 112 is located in the first protection space. One side of the first protection space facing the positioning mechanism 12 is open for the lens 60 to enter the first protection space, and the spraying port of the spraying mechanism 13 is located in the first protection space.

[0078] The spraying port is used for the polishing liquid to spray out of the spraying mechanism 13.

[0079] The first shield 114 can move synchronously with the polishing head 112 along the first direction.

[0080] When the lens 60 enters the first protection space, the polishing head 112 polishes the lens 60 in the first protection space, and the spraying port sprays the polishing liquid. Through the shielding of the first shield 114, the splashing range of the splashing polishing liquid on the lens polishing equipment can be reduced, which is beneficial to reducing the adverse effects of the polishing liquid on other devices in the lens polishing equipment.

[0081] In some embodiments, at least part of the first shield 114 is made of a transparent material so that the operator can observe the polishing operation of the lens 60 from the outside.

[0082] In some embodiments, a part of the first shield 114 can be opened for repairing the polishing head 112.

[0083] In some embodiments, refer to Figure 1 , the polishing mechanism 11 further includes a first outer shell 115. A first installation space is provided in the first outer shell 115, and at least part of the polishing driving device 111 is located in the first installation space to play a role in protection.

[0084] In some embodiments, the polishing module 10 further includes a first air blowing mechanism. The air outlet of the first air blowing mechanism is located within the first protection space and is used to blow air flow towards at least one of the polishing head 112 and the lens 60. In this way, it is possible to reduce the deposition of particles in the polishing liquid on the lens 60.

[0085] In some embodiments, the polishing mechanism 11 includes a hollow shaft. The universal joint 113 connects the hollow shaft and the polishing head 112. A through hole is provided in the hollow shaft to reduce the weight of the hollow shaft.

[0086] In some embodiments, the polishing head 112 includes a polishing body and a mounting disk. The polishing body and the mounting disk are detachably configured. The mounting disk is provided with a plurality of through-flow diversion channels. The polishing body covers the open end of the mounting disk. The polishing body is used to polish the lens 60. The polishing liquid flowing out from the diversion channels can contact the polishing body. After the polishing body is worn out after long-term use, the polishing body and the mounting disk can be disassembled to replace with a new polishing body.

[0087] The specific material of the polishing body can be felt or the like.

[0088] In some embodiments, referring to Figure 6 , the polishing drive device 111 includes a first rotating motor 1113 and a first transmission belt 1114. The output end of the first rotating motor 1113 forms a belt drive with the hollow shaft through the first transmission belt 1114 to drive the hollow shaft to rotate about its axis in the first direction. In this way, it is beneficial to reduce the noise during the transmission process and make the transmission stable.

[0089] In some embodiments, the first transmission belt 1114 is a multi-wedge belt.

[0090] In some embodiments, the first transmission belt 1114 can synchronously drive a plurality of hollow shafts to rotate.

[0091] In some embodiments, the polishing drive device 111 further includes a first pulley. The hollow shaft passes through the first pulley and the two are fixed. The first transmission belt 1114 meshes with the first pulley to form a belt drive.

[0092] In some embodiments, referring to Figure 2 , the polishing drive device 111 includes a second driver 1115. The first driver 1111 is arranged at the driving end of the second driver 1115 to drive the first driver 1111 to move in the second direction.

[0093] The specific type of the second driver 1115 is not limited. For example, it can be a linear module, a telescopic cylinder, a telescopic electric cylinder, etc.

[0094] In some embodiments, the positioning driving device includes a second rotating motor and a second transmission belt. The output end of the second rotating motor is in belt transmission with the positioning suction head 121 through the second transmission belt to drive the positioning suction head 121 to rotate about the axis in the first direction. In this way, it is beneficial to reduce the noise during the transmission process and make the transmission stable.

[0095] In some embodiments, referring to Figure 7 , the positioning suction head 121 includes a tooth wedge 121a, and the tooth wedge 121a can be engaged with the second transmission belt to achieve the purpose of forming a belt transmission between the second transmission belt and the positioning suction head 121 and improve the friction between the two.

[0096] In some embodiments, the second transmission belt is a multi-wedge belt.

[0097] In some embodiments where the first direction is the vertical direction, referring to Figure 2 and Figure 11 , the polishing module 10 further includes a first collection tank 14. The first collection tank 14 is provided with a first accommodation space, and the top of the first accommodation space is open and faces the open position of the first protection space. In this way, the used polishing liquid can enter the first accommodation space to reduce the splashing range of the polishing liquid on the lens polishing equipment and facilitate subsequent processing.

[0098] In some embodiments, the spraying mechanism 13 is communicated with the first accommodation space to recycle the polishing liquid in the first accommodation space.

[0099] In some embodiments, the bottom wall of the first accommodation space is an inclined surface to converge the polishing liquid.

[0100] In some embodiments, referring to Figure 12 , the polishing module 10 further includes a stirring device 16. The spraying mechanism 13 is communicated with the stirring chamber of the stirring device 16, and the stirring device 16 can stir the polishing liquid so that the components of the polishing liquid are fully mixed before being supplied to the spraying mechanism 13.

[0101] In some embodiments, referring to Figure 12 , the polishing module 10 includes a circulation pump 15. The circulation pump 15 is communicated with the spraying mechanism 13 and the stirring device 16 to continuously pump the polishing liquid to the spraying mechanism 13.

[0102] In some embodiments, referring to Figure 12 , the polishing module 10 includes an emptying valve 151. The emptying valve 151 can selectively communicate the stirring chamber and the first accommodation space to drain the polishing liquid in the first accommodation space into the first accommodation space.

[0103] In some embodiments, referring to Figure 12, the polishing module 10 includes a vacuum generating assembly. The vacuum generating assembly includes a vacuum generator 152, a vacuum control valve 153, a vacuum buffer valve 154, and a vacuum break valve path 155. The vacuum control valve 153 selectively connects the vacuum buffer valve 154 and the vacuum generator 152. The vacuum buffer valve 154 is connected to the positioning suction head 121. The vacuum break valve path 155 selectively connects the outside to the vacuum buffer valve 154.

[0104] The vacuum generator 152 is used to extract air flow. In the state where the vacuum control valve 153 is open, the positioning suction head 121 can generate negative pressure to adsorb the lens 60. The vacuum buffer valve 154 is used to slow down the impact of air pressure changes on each device in the air path of the vacuum generating assembly. The vacuum break valve path 155 is used to allow outside air flow to enter the air path of the vacuum generating assembly in its open state, so as to reduce the risk of damage to the vacuum generating assembly due to excessive pressure difference with the outside.

[0105] In some embodiments, refer to Figure 12 , the polishing module 10 includes a lower discharge valve 156. The lower discharge valve 156 selectively connects the positioning suction head 121 to the stirring chamber. So that in the case where the lens 60 needs to be separated from the positioning suction head 121, the lower discharge valve 156 is opened, so that the normal atmospheric pressure can be quickly restored inside the positioning suction head 121, facilitating the separation of the lens 60 from the positioning suction head 121, and also enabling the polishing liquid that enters the positioning suction head 121 to be discharged into the stirring chamber.

[0106] In some embodiments, refer to Figure 1 and Figure 8 , the cleaning module 20 is located on one side of the polishing module 10 along the second direction. The transfer module 30 includes a transfer driving device 31 and a clamping mechanism 32. The clamping mechanism 32 is drivingly engaged with the transfer driving device 31 to drive the clamping mechanism 32 to move along the first direction, the second direction, and the third direction. The first direction, the second direction, and the third direction intersect with each other. The clamping mechanism 32 is used to clamp the lens 60.

[0107] The transfer driving device 31 drives the clamping mechanism 32 to move along the first direction, so that after the clamping mechanism 32 clamps the lens 60, it can move along the first direction away from the positioning suction head 121, reducing the risk of damage caused by friction between the lens 60 and the positioning suction head 121 during the subsequent movement of the lens 60. The transfer driving device 31 drives the clamping mechanism 32 to move along the second direction, so as to transfer the lens 60 on the clamping mechanism 32 along the second direction to the cleaning module 20. The transfer driving device 31 drives the clamping mechanism 32 to move along the third direction, so that during the polishing of the lens 60 by the polishing module 10, the movement of the clamping mechanism 32 is difficult to interfere with the operation of the polishing module 10, so that the movement of the clamping mechanism 32 and the polishing of the polishing module 10 can be synchronized, which is beneficial to improving the operation efficiency of the lens polishing equipment.

[0108] In some embodiments, the first direction, the second direction, and the third direction are perpendicular to each other.

[0109] The specific type of the clamping mechanism 32 is not limited, such as a jaw cylinder, a jaw electric cylinder, etc.

[0110] In some embodiments, referring to Figure 8 , the clamping mechanism 32 encloses to form a clamping space. One side of the clamping space is open to form an inlet / outlet for the lens 60 to enter and exit the clamping space. A buffer member 33 is provided on the inner wall of the clamping space perpendicular to the first direction. The buffer member 33 can undergo elastic deformation and is used to abut against the lens 60. By means of the buffer member 33, the risk of damage to the clamped lens 60 can be reduced.

[0111] The specific form of the buffer member 33 is not limited, such as a spring, a rubber member, a rubber roller, etc.

[0112] In some embodiments, referring to Figure 1 , Figure 2 and Figure 8 , the numbers of the polishing module 10 and the clamping mechanism 32 are both multiple. The multiple polishing modules 10 are arranged along the second direction, and the multiple clamping mechanisms 32 are arranged along the second direction.

[0113] In this way, it is beneficial to polish multiple lenses 60 synchronously, and the clamping mechanism 32 transfers multiple lenses 60 to the cleaning module 20 at one time, which is beneficial to improving the efficiency of the polishing operation.

[0114] The stroke of the transfer driving device 31 driving the clamping mechanism 32 to move along the second direction to transfer the lens 60 from the positioning suction head 121 to the cleaning module 20 is an integer multiple of the distance between the central positions of the clamping spaces of two adjacent clamping mechanisms 32 along the second direction.

[0115] It can be understood that in some cases, both opposite surfaces of the lens 60 along the first direction need to be polished.

[0116] In some embodiments, referring to Figure 8 , the transfer module 30 further includes a first flipping device 34. The first flipping device 34 is drivingly cooperated with the transfer driving device 31 to drive the first flipping device 34 to be able to move along the first direction, the second direction, and the third direction. The clamping mechanism 32 includes a first clamping sub-mechanism 321. The first clamping sub-mechanism 321 is drivingly cooperated with the first flipping device 34 to drive the first clamping sub-mechanism 321 to rotate and the rotation axis is perpendicular to the first direction. The first clamping sub-mechanism 321 is used to place the lens 60 on one positioning suction head 121 on another positioning suction head 121 of the polishing module 10.

[0117] In this way, the first clamping sub-mechanism 321 can flip the lens 60 and then transfer the lens 60 to another positioning suction head 121, so that after the one side surface of the lens 60 along the first direction is polished, the other side surface can also be polished, thereby completing the polishing of both side surfaces of the lens 60 along the first direction on the same lens polishing device, which is beneficial to improving the operation efficiency.

[0118] The number of the first clamping sub-mechanisms 321 can be one or multiple.

[0119] The specific type of the first flipping device 34 is not limited. For example, it can be a rotary air cylinder or a rotary electric cylinder. Also, for example, the first flipping device 34 includes a telescopic air cylinder, a rack and a gear. The first clamping sub-mechanism 321 is arranged on the gear. The telescopic air cylinder is in driving cooperation with the rack to drive the rack to extend and retract, and the rack meshes with the gear to drive the gear to rotate.

[0120] In some embodiments, referring to Figure 8 , the transfer module 30 further includes a second flipping device 35. The second flipping device 35 is in driving cooperation with the transfer driving device 31 to drive the second flipping device 35 to be able to move along the first direction, the second direction and the third direction. The clamping mechanism 32 includes a second clamping sub-mechanism 322. The second clamping sub-mechanism 322 is in driving cooperation with the second flipping device 35 to drive the second clamping sub-mechanism 322 to rotate and the rotation axis is perpendicular to the first direction. The second clamping sub-mechanism 322 is used to place the lens 60 on a positioning suction head 121 onto the cleaning module 20.

[0121] In this way, the lens 60 can be flipped again through the second flipping device 35, so that after the lens 60 is flipped by the first flipping device 34, the appropriate surface of the lens 60 can be selected for cleaning as needed to improve the cleaning efficiency of the lens 60.

[0122] For example, one side surface of the lens 60 along the first direction is a convex surface and the other side is a concave surface. First, the convex surface is polished by the polishing head 112 of a polishing module 10, then the first flipping device 34 flips the lens 60 to polish the concave surface by the polishing head 112 of another polishing module 10, and then the second flipping device 35 flips the lens 60 again to make the convex surface face upward, and the cleaning module 20 is used to clean the lens 60 to reduce the residue of the cleaning liquid on the lens 60.

[0123] The number of the second clamping sub-mechanisms 322 can be one or multiple.

[0124] The specific type of the second flipping device 35 is not limited. For example, it can be a rotary cylinder or a rotary electric cylinder. Alternatively, the second flipping device 35 includes a telescopic cylinder, a rack, and a gear. The second clamping sub-mechanism 322 is provided on the gear. The telescopic cylinder is drivingly engaged with the rack to drive the rack to extend and retract, and the rack is meshed with the gear of the second driving mechanism 312 to drive the gear to rotate.

[0125] In some embodiments, referring to Figure 8 , the transfer driving device 31 includes a first driving mechanism 311, a second driving mechanism 312, and a third driving mechanism 313. The second driving mechanism 312 is provided at the driving end of the first driving mechanism 311 so that the first driving mechanism 311 drives the second driving mechanism 312 to move in the third direction. The third driving mechanism 313 is provided at the driving end of the second driving mechanism 312 so that the second driving mechanism 312 drives the third driving mechanism 313 to move in the first direction. The clamping mechanism 32 is drivingly engaged with the driving end of the third driving mechanism 313 so that the third driving mechanism 313 drives the clamping mechanism 32 to move in the second direction.

[0126] In this way, the purpose that the clamping mechanism 32 can move in the first direction, the second direction, and the third direction in space respectively is achieved.

[0127] The specific type of the first driving mechanism 311 is not limited. It can be a linear module, a telescopic electric cylinder, a telescopic cylinder, a gear and rack matching mechanism, etc.

[0128] The specific type of the second driving mechanism 312 is not limited. It can be a linear module, a telescopic electric cylinder, a telescopic cylinder, a gear and rack matching mechanism, etc.

[0129] The specific type of the third driving mechanism 313 is not limited. It can be a linear module, a telescopic electric cylinder, a telescopic cylinder, a gear and rack matching mechanism, etc.

[0130] In some embodiments, referring to Figure 3 , Figure 9 and Figure 10 , the cleaning module 20 includes a cleaning driving mechanism 21, a first cleaning mechanism 22, and a clamping and fixing mechanism 23. The first cleaning mechanism 22 is drivingly engaged with the cleaning driving mechanism 21 to drive the first cleaning mechanism 22 to move in the first direction. The clamping area of the clamping and fixing mechanism 23 is used to clamp the lens 60 perpendicular to the first direction. The nozzle of the first cleaning mechanism 22 is used to spray cleaning liquid onto the lens 60.

[0131] The cleaning driving mechanism 21 drives the first cleaning mechanism 22 to move in the first direction, which is beneficial to keeping the first cleaning mechanism 22 away from the clamping and fixing mechanism 23 during the process of transferring the lens 60 from the positioning suction head 121 to the clamping and fixing mechanism 23, and is beneficial to reducing the probability of interference between the first cleaning mechanism 22 and the transfer module 30; during the process of the first cleaning mechanism 22 spraying cleaning liquid onto the lens 60, it is beneficial to make the nozzle of the first cleaning mechanism 22 close to the lens 60, thereby improving the efficiency of cleaning the lens 60.

[0132] The specific type of the cleaning driving mechanism 21 is not limited, and it can be a linear module, a telescopic electric cylinder, a telescopic air cylinder, etc.

[0133] The specific type of the clamping and fixing mechanism 23 is not limited. For example, refer to Figure 10 , the clamping and fixing mechanism 23 includes a first jaw cylinder 231 and two clamping components. Each clamping component is respectively arranged on a jaw of the first jaw cylinder 231. The clamping rod 233 component includes a connecting rod 232 and a clamping rod 233. The connecting rod 232 connects the jaw and the clamping rod 233, and the clamping rod 233 extends in the first direction.

[0134] The specific type of the cleaning liquid is not limited, such as water.

[0135] In some embodiments, refer to Figure 1 , the cleaning module 20 further includes a second shield 24. The second shield 24 is drivingly engaged with the cleaning driving mechanism 21 to drive the second shield 24 to move in the first direction. The second shield 24 is provided with a second protection space. The nozzle of the first cleaning mechanism 22 is located in the second protection space. The side of the second protection space facing the positioning mechanism 12 is open for the clamping area of the clamping and fixing mechanism 23 to enter the second protection space.

[0136] The second shield 24 can move synchronously with the first cleaning mechanism 22 in the first direction.

[0137] When the lens 60 enters the second protection space, the nozzle of the first cleaning mechanism 22 sprays cleaning liquid on the lens 60 in the first protection space. Through the shielding of the second shield 24, the splashing range of the splashing cleaning liquid on the lens polishing equipment can be reduced, which is beneficial to reducing the adverse effects of the cleaning liquid on other devices in the lens polishing equipment.

[0138] In some embodiments, at least part of the second shield 24 is made of a transparent material so that the operator can observe the cleaning operation of the lens 60 from the outside.

[0139] In some embodiments, a part of the second shield 24 can be opened for repairing the first cleaning mechanism 22.

[0140] In some embodiments, refer to Figure 1The cleaning module 20 further includes a second housing 25 , in which a second installation space is defined. At least a portion of the cleaning drive mechanism 21 is located in the second installation space for protection.

[0141] In some embodiments, the cleaning module 20 further includes a second blowing mechanism, the air outlet of which is located in the second protective space, for blowing air toward the lens 60, thereby reducing the retention of cleaning liquid on the lens 60 and reducing the residual cleaning liquid from dripping into other areas of the lens polishing equipment.

[0142] In some embodiments, see Figure 3 and Figure 10 The clamping area of the clamping fixing mechanism 23 is provided with a positioning space that penetrates along the first direction. The cleaning module 20 also includes a second cleaning mechanism 26. The nozzle of the second cleaning mechanism 26 is located on the side of the clamping area away from the first cleaning mechanism 22 along the first direction.

[0143] The cleaning liquid sprayed by the nozzle of the second cleaning mechanism 26 can contact the lens 60 through the open position of the positioning space.

[0144] In this way, both sides of the lens 60 along the first direction can be cleaned, further reducing the residue of polishing liquid on the surface of the lens 60 and improving the cleanliness of the surface of the lens 60.

[0145] It is understandable that the first cleaning mechanism 22 and the second cleaning mechanism can share the same cleaning water tank to reduce the number of parts in the lens polishing equipment.

[0146] In some embodiments, when the second protective space cover is disposed in the clamping area of the clamping and fixing mechanism 23 , the nozzle of the second cleaning mechanism 26 is located in the second protective space.

[0147] In this way, the nozzle of the second cleaning mechanism 26 sprays cleaning liquid onto the lens 60 in the first protective space. Through the shielding of the second protective cover 24, the splashing range of the splashing cleaning liquid on the lens polishing equipment can be reduced, which is beneficial to reducing the adverse effects of the cleaning liquid on other devices in the lens polishing equipment.

[0148] In some embodiments where the first direction is a vertical direction, see Figure 2 and Figure 11 The cleaning module 20 also includes a second collecting tank 27, which is provided with a second accommodating space 27a. The top of the second accommodating space 27a is open and faces the open position of the second protective space. In this way, the used cleaning liquid can enter the second accommodating space 27a to reduce the splashing range of the cleaning liquid on the lens polishing equipment, which is convenient for subsequent processing.

[0149] In some embodiments, the second cleaning mechanism 26 is disposed in the second accommodation space 27a to reduce the splashing range of the cleaning liquid ejected by the second cleaning mechanism 26 on the lens polishing equipment.

[0150] In some embodiments, referring to Figure 1 , Figure 2 and Figure 4 , the lens polishing equipment further includes a loading module 40. The loading module 40 includes a loading conveyor belt 41, a stop block 42, a sensor, and a loading handling mechanism 43. The stop block 42 is disposed on the surface of the loading conveyor belt 41. A positioning groove 42a is provided on the upstream side of the stop block 42 facing the conveying direction of the loading conveyor belt 41. The positioning groove 42a is open on the upstream side facing the conveying direction of the loading conveyor belt 41 for at least a part of the lens 60 to enter the positioning groove 42a. The distance between the inner walls on both sides of the positioning groove 42a perpendicular to the conveying direction of the loading conveyor belt 41 gradually decreases along the conveying direction of the loading conveyor belt 41. The sensor is used to confirm that the lens 60 on the loading conveyor belt 41 abuts against both inner walls of the positioning groove 42a perpendicular to the conveying direction of the loading conveyor belt 41. The loading handling mechanism 43 is used to transfer the lens 60 on the loading conveyor belt 41 to the transfer module 30.

[0151] An operator can directly place the lens 60 to be polished on the loading conveyor belt 41. The loading conveyor belt 41 drives the lens 60 to be polished to move until the lens 60 to be polished contacts the stop block 42. Under the drive of the loading conveyor belt 41, at least a part of the lens 60 to be polished enters the positioning groove 42a and abuts against at least one of the inner walls on both sides of the positioning groove 42a perpendicular to the conveying direction of the loading conveyor belt 41. One of the inner walls on both sides of the positioning groove 42a perpendicular to the conveying direction of the loading conveyor belt 41 that contacts the lens 60 to be polished can apply a force perpendicular to the conveying direction of the loading conveyor belt 41 and pointing to the other inner wall to the lens 60 to be polished, so that the lens 60 to be polished moves perpendicular to the conveying direction of the loading conveyor belt 41 on the loading conveyor belt 41 until the lens 60 to be polished abuts against both inner walls perpendicular to the conveying direction of the loading conveyor belt 41, thereby realizing that the lens 60 to be polished reaches the specified position along the conveying direction of the loading conveyor belt 41 and perpendicular to the conveying direction of the loading conveyor belt 41 on the loading conveyor belt 41.

[0152] In this way, during the loading process, an operator can place the lens 60 to be polished at any position on the loading conveyor belt 41 to enable the lens 60 to be polished to finally reach the specified position for the loading handling mechanism 43 to carry, reducing the operation requirements and being beneficial to improving the operation efficiency.

[0153] After the sensor confirms that the lens 60 to be polished reaches the specified position on the loading conveyor belt 41, the loading handling mechanism 43 obtains the in-place signal of the lens 60 to be polished and transfers the lens 60 on the loading conveyor belt 41 to the transfer module 30.

[0154] The specific type of the sensor is not limited, such as a fiber optic sensor.

[0155] In some embodiments, referring to Figure 2 and Figure 4 , the polishing module 10 is located on one side of the loading conveyor belt 41 along the second direction. The loading handling mechanism 43 includes a loading driving mechanism 431 and a loading fixing mechanism 432. The loading fixing mechanism 432 is drivingly engaged with the loading driving mechanism 431 to drive the loading fixing mechanism 432 to move at least along the first direction and the second direction. The loading fixing mechanism 432 is used to fix the lens 60. The loading module 40 further includes a transfer suction head 44. The transfer suction head 44 is located between the positioning suction head 121 and the loading conveyor belt 41. The transfer suction head 44 is used to adsorb the lens 60 along the first direction. The transfer module 30 is further used to transfer the lens 60 on the transfer suction head 44 to the positioning suction head 121.

[0156] The loading driving mechanism 431 drives the loading fixing mechanism 432 to move along the second direction to reach above the loading conveyor belt 41, and then drives the loading fixing mechanism 432 to move along the first direction to fix the lens 60 and continue to move in the reverse direction along the first direction to separate the lens 60 from the loading conveyor belt 41. The loading driving mechanism 431 drives the loading fixing mechanism 432 to move along the second direction to reach one side of the transfer suction head 44 along the first direction, so that the transfer suction head 44 adsorbs the lens 60, and then the loading fixing mechanism 432 is separated from the lens 60.

[0157] The specific type of the loading fixing mechanism 432 is not limited, such as a vacuum suction cup, a clamping jaw cylinder, etc.

[0158] In some embodiments, the positioning suction head 121 and the transfer suction head 44 have the same structure, and the two only have different functions.

[0159] In some embodiments, referring to Figure 2 , the loading driving mechanism 431 includes a first handling mechanism 4311 and a second handling mechanism 4312. The second handling mechanism 4312 is arranged at the driving end of the first handling mechanism 4311, so that the first handling mechanism 4311 drives the second handling mechanism 4312 to move along the second direction. The loading fixing mechanism 432 is arranged at the driving end of the second handling mechanism 4312, so that the second handling mechanism 4312 drives the loading fixing mechanism 432 to move along the first direction.

[0160] The first handling mechanism 4311 can be a linear module, a telescopic electric cylinder, a telescopic cylinder, etc.

[0161] The second transport mechanism 4312 can be a linear module, a telescopic electric cylinder, a telescopic air cylinder, etc.

[0162] It is understandable that the process of the loading drive mechanism 431 driving the loading fixing mechanism 432 to obtain the lens 60 from the loading conveyor belt 41 can overlap partially with the process of the transfer module 30 transferring the lens 60 on the transfer suction head 44 to the positioning suction head 121 to improve operating efficiency.

[0163] In some embodiments, see Figure 8 The clamping mechanism 32 includes a third clamping sub-mechanism 323 , which is used to transfer the lens 60 on the transfer suction head 44 to the positioning suction head 121 .

[0164] In some embodiments, the lens polishing apparatus further comprises a gantry, which is arranged across the second direction, and the polishing drive device 111, the cleaning drive mechanism 21 and the feeding drive mechanism 431 are all arranged on the gantry.

[0165] In some embodiments, see Figure 1 and Figure 2 The lens polishing equipment also includes a blanking module 50, which includes a blanking conveyor belt 51 and a blanking transport mechanism 52. The blanking transport mechanism 52 is used to transport the lenses 60 of the cleaning module 20 to the blanking conveyor belt 51 so that the operator can collect the polished lenses 60.

[0166] In some embodiments, see Figure 2 and Figure 5 The unloading module 50 also includes a unloading suction head 53, which is located on one side of the positioning suction head 121 along the second direction. The unloading and transporting mechanism 52 includes a unloading driving mechanism 521 and a unloading fixing mechanism 522. The unloading fixing mechanism 522 cooperates with the unloading driving mechanism 521 to drive the unloading fixing mechanism 522 to move at least along the first direction and perpendicular to the first direction. The unloading fixing mechanism 522 is used to fix the lens 60, and the unloading suction head 53 is used to adsorb the lens 60 along the first direction. The transfer module 30 is also used to transfer the lens 60 under the positioning suction head 121 to the unloading suction head 53.

[0167] After the transfer module 30 transfers the lens 60 from the positioning nozzle 121 to the unloading nozzle 53, the unloading drive mechanism 521 drives the unloading and fixing mechanism 522 to move in the second direction to reach above the unloading nozzle 53. The unloading and fixing mechanism 522 then drives the unloading and fixing mechanism 522 to move in the first direction to fix the lens 60 and then continues to move in the opposite direction of the first direction to release the lens 60 from the unloading nozzle 53. The unloading drive mechanism 521 drives the unloading and fixing mechanism 522 to move perpendicularly to the first direction to reach above the unloading conveyor belt 51. The unloading and fixing mechanism 522 then disengages from the lens 60, allowing the lens 60 to reach the unloading conveyor belt 51.

[0168] The specific type of the blanking fixing mechanism 522 is not limited, such as a vacuum chuck, a jaw cylinder, etc.

[0169] In some embodiments, the positioning suction head 121 has the same structure as the blanking suction head 53, and the two only have different functions.

[0170] In some embodiments, referring to Figure 2 and Figure 5 , the blanking driving mechanism 521 includes a third handling mechanism 5211 and a fourth handling mechanism 5212. The fourth handling mechanism 5212 is arranged at the driving end of the third handling mechanism 5211, so that the third handling mechanism 5211 drives the fourth handling mechanism 5212 to move along the third direction. The blanking fixing mechanism 522 is arranged at the driving end of the fourth handling mechanism 5212, so that the fourth handling mechanism 5212 drives the blanking fixing mechanism 522 to move along the first direction.

[0171] The third handling mechanism 5211 can be a linear module, a telescopic electric cylinder, a telescopic cylinder, etc.

[0172] The fourth handling mechanism 5212 can be a linear module, a telescopic electric cylinder, a telescopic cylinder, etc.

[0173] It can be understood that the process of the blanking driving mechanism 521 driving the blanking fixing mechanism 522 to place the lens 60 on the blanking conveyor belt 51 can overlap with the process of the transfer module 30 transferring the lens 60 of the cleaning module 20 to the blanking suction head 53 for a part of the time, so as to improve the operation efficiency.

[0174] In some embodiments, referring to Figure 8 , the clamping mechanism 32 includes a fourth clamping sub-mechanism 324, and the fourth clamping sub-mechanism 324 is used to transfer the lens 60 on the clamping and fixing mechanism 23 to the blanking suction head 53.

[0175] In some embodiments, the first clamping sub-mechanism 321, the second clamping sub-mechanism 322, the third clamping sub-mechanism 323 and the fourth clamping sub-mechanism 324 have the same type, and only the functions realized are different.

[0176] In some embodiments, referring to Figure 11 , the second collection tank 27 is provided with a third accommodation space 27b, and the top of the third accommodation space 27b is open and faces the blanking fixing mechanism 522. In this way, during the process of the blanking fixing mechanism 522 transporting the lens 60, the cleaning liquid dripping from the lens 60 can enter the third accommodation space 27b, so as to reduce the splashing range of the cleaning liquid on the lens polishing equipment and facilitate subsequent processing.

[0177] In some embodiments, the blanking suction head 53 is arranged in the third accommodation space 27b to reduce the splashing range of the cleaning liquid dripping from the lens 60 on the blanking suction head 53 on the lens polishing equipment.

[0178] In some embodiments, the bottom wall of the second accommodation space 27a is an inclined surface to converge the cleaning liquid.
