If "first," "second," etc., are used in the description, they are only for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0045] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0046] Please refer to Figure 1 and Figure 2 As shown, in one aspect, this utility model provides a lens film-peeling mechanism and a lens production equipment. The lens film-peeling mechanism includes a film-peeling module 100, a positioning and conveying module 200, and a feeding module 300. The film-peeling module 100 includes a film-peeling gripper 110 and a film-peeling drive 120. The film-peeling gripper 110 can open and close vertically and can move along a first direction under the drive of the film-peeling drive 120. The positioning and conveying module 200 includes a first positioning platform assembly 210 and a first conveying linear module 220 extending along a second direction. The first positioning platform assembly 210 is adapted to move under the drive of the first conveying linear module 220 and switch between the feeding station and the film-peeling station. The feeding module 300 includes a movable feeding gripper 310, which connects the feeding station and the upstream station. The first direction, the second direction, and the vertical direction are all angularly arranged.

[0047] According to the lens film peeling mechanism of this utility model embodiment, the loading gripper 310 of the loading module 300 clamps and transports the lens from the upstream station to the first positioning platform assembly 210 of the loading station. The first transport linear module 220 drives the first positioning platform assembly 210 to carry the lens to the film peeling station. The film peeling drive 120 drives the film peeling gripper 110 to move to the protective film position of the lens to clamp the protective film. At least one of the film peeling drive 120 and the first transport linear module 220 works to realize the relative movement between the film peeling gripper 110 and the lens, and peel the protective film off the lens.

[0048] It should be noted that when the grippers of the lens film-tearing mechanism of the relevant technology pick up and tear the protective film, they usually use a method of tearing the film perpendicular to the lens surface. This can lead to brittle breakage of the protective film and local delamination, resulting in some protective film residue and affecting the optical testing results.

[0049] According to the lens film-tearing mechanism of this utility model embodiment, by making the moving direction of the film-tearing gripper 110 at a certain angle to the direction of the protective film surface, the oblique tearing during manual film tearing is achieved. The tensile force is vector-decomposed along the tear line, forming a gradual peeling. The protective film is subjected to shear stress greater than tensile stress, making it easier to separate continuously. Furthermore, the film-tearing drive 120 with an inclined angle can effectively reduce the height occupied by the film-tearing module 100 in the vertical direction.

[0050] In this embodiment, the film-tearing drive component 120 is a cylinder, but it can also be a lead screw module, a slide module, etc.

[0051] In this embodiment, the first linear conveying module 220 is a lead screw slide module. Of course, it can also be a cylinder, lead screw module, slide module, etc.

[0052] In this embodiment, the "upstream station" can be the discharge station of the upstream equipment or a separately set station for manual loading.

[0053] In this embodiment, the second direction is perpendicular to the vertical direction, the first direction is set at 90 degrees to the second direction, and the first direction is set at 45 degrees to the vertical direction. The specific angle can be adjusted according to actual needs to ensure that the protective film can be torn at an angle.

[0054] In some embodiments, combined with Figure 1 , Figure 3 and Figure 4 As shown, the lens film peeling mechanism also includes a rotary lifting module 400, which connects the loading gripper 310 to the first positioning platform assembly 210 located at the loading station. The rotary lifting module 400 includes a suction nozzle 410, a rotating assembly 420, and a lifting assembly 430. The suction nozzle 410 is adapted to rotate under the drive of the rotating assembly 420 and to move up and down in the vertical direction under the drive of the lifting assembly 430. The rotation axis of the rotating assembly 420 is perpendicular to the second direction and the vertical direction.

[0055] In this embodiment, the rotating assembly 420 drives the suction nozzle 410 upward to correspond with the lens being transported by the loading gripper 310. The lifting assembly 430 drives the suction nozzle 410 to rise and abut against the lens. After the suction nozzle 410 adsorbs the lens, the lifting assembly 430 drives the suction nozzle 410 to move downward. The rotating assembly 420 drives the suction nozzle 410 to rotate downward with the lens. The lifting assembly 430 then drives the suction nozzle 410 to descend again to place the lens on the first positioning platform assembly 210. The lens is transferred and loaded by adsorbing the lens through the suction nozzle 410. The deformation of the suction nozzle 410 itself can avoid hard contact during the lens transfer process, effectively protecting the lens.

[0056] In this embodiment, the rotating component 420 may include a rotating motor, a rotating shaft, and a timing belt. The rotating motor drives the rotating shaft to rotate via the timing belt, thereby causing the suction nozzle 410 at the end of the rotating shaft to rotate. Of course, the rotating motor can also be used directly to drive the rotating shaft to rotate.

[0057] In this embodiment, the lifting component 430 is a lead screw module, but it can also be a cylinder, a slide module, etc.

[0058] In some embodiments, the rotary lifting module 400 includes two suction nozzles 410, which are arranged opposite to each other around the rotation axis of the rotary assembly 420. The dual suction nozzles 410 arrangement allows the drive shaft of the suction nozzles 410 to rotate only 180 degrees when switching between up and down, and the corresponding pipes and lines connected to the suction nozzles 410 also only need to rotate 180 degrees, effectively avoiding damage to the pipes and lines due to excessive rotation. Furthermore, the dual suction nozzles 410 only require moving the lifting assembly 430 for each material pick-up and unloading operation, effectively improving the handling efficiency of the rotary lifting module 400.

[0059] In some embodiments, combined with Figure 1 and Figure 2 As shown, the feeding module 300 also includes a first picking and placing unit 320. The movable end of the first picking and placing unit 320 is connected to the feeding gripper 310, and the movable plane where the movable end of the first picking and placing unit 320 is located is parallel to the vertical direction and is set at an acute angle to the second direction.

[0060] In this embodiment, the pick-and-place unit (first pick-and-place unit 320) is existing technology and is a pure cam structure transfer device. Its movable end usually moves back and forth between two points on a movable plane. The first pick-and-place unit 320 is used to drive the loading gripper 310, which can save the design and manufacturing cost of the lens film tearing mechanism.

[0061] In this embodiment, taking into account the characteristic that the movable end of the first pick-and-place unit 320 can only move in the movable plane, the movable plane of the first pick-and-place unit 320 is tilted (at an angle with the first linear conveying module), so that the loading gripper 310 driven by the first pick-and-place unit 320 has displacement not only in the second direction (X direction), but also in the direction perpendicular to the second direction (Y direction), such as Figure 2 As shown, when perpendicular to the horizontal plane, the loading gripper 310 can move outside the range of the positioning and conveying module 200, making it easier for the loading module 300 to connect to the upstream station.

[0062] In other embodiments, the driving form of the feeding gripper 310 can also be a combination of several linear modules, a robotic arm, etc.

[0063] In some embodiments, combined with Figures 1 to 4 As shown, the first positioning platform assembly 210 includes a loading platform 211, positioning grippers 212, and gripper drive (not shown in the figure). The gripping arms of the positioning grippers 212 are located on both sides of the loading platform 211 along the second direction (X direction). The positioning grippers 212 can open and close under the drive of the gripper drive. The loading platform 211 is provided with a first positioning surface 2111 perpendicular to the vertical direction and two second positioning surfaces 2112 perpendicular to the first positioning surface 2111. The two second positioning surfaces 2112 are symmetrically arranged with respect to the first conveying linear module 220. The positioning grippers 212 are provided with a clearance for the tearing gripper 110 to pass through.

[0064] In this embodiment, the lens is placed on the first positioning surface 2111, and the second positioning surface 2112 achieves Y-direction positioning. Then, the positioning gripper 212 clamps the lens to achieve X-direction positioning. The fixed lens is transported to the film-peeling station, and the film-peeling gripper 110 clamps the protective film from the clearance opening.

[0065] In this embodiment, the gripper drive can be a cylinder, a slide module, or the like.

[0066] In some embodiments, combined with Figure 1 , Figure 2 and Figure 5 As shown, the lens film-removing mechanism also includes a waste film recycling module 500, which includes a waste film recycling bin 510; the film-removing module 100 also includes a film-removing conveying linear module 130, and the film-removing gripper 110 can connect the film-removing station and the waste film recycling bin 510 under the drive of the film-removing conveying linear module 130.

[0067] In this embodiment, the film-tearing and conveying linear module 130 drives the film-tearing claw 110 holding the waste film to move above the waste film recycling bin 510, where the waste film is recycled by the waste film recycling bin 510, ensuring that the inside of the lens film-tearing mechanism is clean and improving the waste film recycling rate.

[0068] In some embodiments, combined with Figure 1 As shown, the waste membrane recycling module 500 also includes a vacuum waste membrane collector 520, which is provided with a vacuum channel. The inlet of the vacuum channel is connected to the membrane tearing gripper 110, and the outlet of the vacuum channel is connected to the waste membrane recycling bin 510.

[0069] In this embodiment, the waste film is guided into the waste film recycling bin 510 by vacuum negative pressure traction to prevent the waste film from deviating from its position during the falling process and affecting the recycling effect of the waste film recycling bin 510.

[0070] In some embodiments, combined with Figure 1 , Figure 2 and Figure 5 As shown, the lens film-peeling mechanism also includes a feeding module 600, which is located downstream of the film-peeling module 100; the first conveying linear module 220 is also provided with a feeding station; the feeding module 600 includes a feeding gripper 610, a second pick-and-place unit 620 and a feeding transfer station 630, and the feeding gripper 610 can connect the feeding station and the feeding transfer station 630 under the drive of the second pick-and-place unit 620.

[0071] In this embodiment, after the lens is peeled off at the peeling station, it is transported by the first positioning platform assembly 210 along the first transport linear module 220 to the unloading station. The second pick-and-place unit 620 drives the unloading gripper 610 to pick up the lens from the first positioning platform assembly 210 and transport it to the unloading transfer station. This allows the first positioning platform assembly 210 to retract under the drive of the first transport linear module 220, preparing for peeling off the next lens, thereby improving the operating efficiency of the lens peeling mechanism.

[0072] In some embodiments, combined with Figures 1 to 3 As shown, the positioning and transport module 200 also includes a second positioning platform assembly 230, a transfer linear module 240, and a second transport linear module 250; the second transport linear module 250 is parallel to the first transport linear module 220; the second positioning platform assembly 230 has the same structure as the first positioning platform assembly 210, the second positioning platform assembly 230 can move under the drive of the second transport linear module 250, and the second positioning platform assembly 230 can move from above the second transport linear module 250 to above the first transport linear module 220 under the drive of the transfer linear module 240.

[0073] In this embodiment, since the second transport linear module 250 is parallel to the first transport linear module 220, any station on the first transport module (loading station, film-tearing station, or unloading station) has a corresponding position on the second transport linear module 250. The second positioning platform assembly 230 can be driven by the transfer linear module 240 to translate to any station above the first transport linear module 220 to perform the corresponding process.

[0074] In this embodiment, by setting the transfer linear module 240, the second positioning platform assembly 230 on the second transport linear module 250 and the first positioning platform assembly 210 on the first transport linear module 220 share the film-tearing module 100, the feeding module 300, etc., which is effectively adapted to modules that use the pick-and-place unit (first pick-and-place unit 320 or second pick-and-place unit 620) as the driving source, and at the same time greatly improves the operating efficiency of the lens film-tearing mechanism.

[0075] On the other hand, this utility model embodiment also provides a lens manufacturing equipment, including a lens film peeling mechanism as described in the above embodiment.

[0076] In the above embodiments, any component that includes the name "linear module" can be implemented using a linear cylinder, a lead screw module, a slide module, etc.

[0077] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
