[0049] The mold opening machine includes a workbench 1, an equipment unit installed on the workbench 1, and a control unit 100 electrically connected to the equipment unit, wherein the equipment unit includes:

[0050] The station mechanism includes a station circulation module 21 and a module positioning module. The station circulation module 21 is used to drive the module positioning module to sequentially pass through a plurality of stations. The plurality of stations at least include a loading station 11, a mold opening station 13 and a unloading station 14. The mold opening station 13 is located between the loading station 11 and the unloading station 14. The module positioning module includes a tray module 22 and a suction cup module 23. The tray module 22 is used to support the lens module. The suction cup module 23 is arranged above the tray module 22. The suction cup module 23 is used to suck up the lens module on the tray module 22.

[0051] A loading mechanism 3, close to the loading station 11 and used to transfer the lens module to the tray module 22 of the loading station 11;

[0052] The mold opening mechanism 8 is close to the mold opening station 13 and is used to open the lens module on the mold opening station 13;

[0053] The mold opening detection mechanism 9 is close to the mold opening station 13 and is used to detect whether the lens module on the mold opening station 13 is successfully molded;

[0054] The unloading mechanism 10 includes an upper mold conveying streamline 101, a lower mold conveying streamline 102, an NG product conveying streamline 103, an upper mold transfer module 104, a lower mold transfer module 105 and an NG product transfer module 106. The upper mold conveying streamline 101 is used to carry the upper mold and drive the upper mold away from the unloading station 14 in the horizontal direction. The lower mold conveying streamline 102 is used to carry the lower mold or the unsuccessful mold opening lens module and drive the lower mold or the unsuccessful mold opening lens module away from the unloading station 14 in the horizontal direction. The NG product conveying streamline 103 is used to The upper mold transfer module 104 carries the unsuccessful mold opening lens module and drives the unsuccessful mold opening lens module away from the above-mentioned unloading station 14 in the horizontal direction. The upper mold transfer module 104 is used to transfer the upper mold on the above-mentioned unloading station 14 to the above-mentioned upper mold conveying line 101. The lower mold transfer module 105 is used to transfer the lower mold or the unsuccessful mold opening lens module on the above-mentioned unloading station 14 to the above-mentioned lower mold conveying line 102. The NG product transfer module 106 is used to transfer the unsuccessful mold opening lens module on the above-mentioned lower mold conveying line 102 to the above-mentioned NG product conveying line 103.

[0055] The above-mentioned workbench 1 serves as the installation base of the entire mold opening machine, and the above-mentioned N stations are relatively fixed to the workbench 1. Assume that the above-mentioned station circulation module 21 drives the module positioning module to pass through the N stations in sequence, and the module positioning module stops at the N stations in sequence to complete a cycle, and then returns to the first station for the next cycle. The module positioning module stops at each station to perform corresponding work. For example, when the module positioning module stops at the loading station 11, the loading mechanism 3 transfers the lens module to the module positioning module of the loading station 11. When the module positioning module stops at the mold opening station 13, the mold opening mechanism 8 opens the mold for the lens module on the module positioning module of the mold opening station 13. When the module positioning module stops at the unloading station 14, the unloading mechanism 10 transfers the lens module in the module positioning module on the unloading station 14 to the next process.

[0056] The mold opening detection mechanism 9 detects whether the mold opening of the lens module on the mold opening station 13 is successful, so that the lens module that has not been successfully molded can be separated during the subsequent unloading. The upper mold transfer module 104 first transfers the upper mold of the unloading station 14 to the upper mold conveying streamline 101, and the lower mold transfer module 105 then transfers the lower mold of the unloading station 14 to the lower mold conveying streamline 102. The NG product transfer module 106 transfers the lens module that has not been successfully molded on the lower mold conveying streamline 102 to the NG product conveying streamline 103. The upper mold conveying streamline 101, the lower mold conveying streamline 102, and the NG product conveying streamline 103 are all belt conveying streamlines, which can continuously and orderly send the lens modules away from the unloading station 14.

[0057] In this embodiment, a tray sensor is disposed on the tray module 22 , and the tray sensor is used to detect the pressure applied to the tray module 22 .

[0058] At the loading station, the suction cup 232 sucks up the lens module, and the lens module is separated from the tray module 22. If the tray sensor detects that there is weight of an object on the tray module 22 of the detection station 12, then self-mold opening occurs at the detection station 12. If the tray sensor detects that there is weight of an object on the tray module 22 of the mold opening station 13, then the mold is opened successfully at the mold opening station 13. Combined with the backrest sensor on the backrest 821, it can be more accurately judged whether the mold is opened successfully at the mold opening station 13.

[0059] In the present embodiment, the mold opening mechanism 8 comprises a tool module 81 and a backrest module 82. The tool module 81 is arranged on the side of the mold opening station 13 and is located on the preset mold opening side of the lens module. The tool module 81 is used to extend into the preset mold opening side gap of the lens module of the mold opening station 13 to separate the upper mold from the lower mold. The backrest module 82 is arranged on the side of the mold opening station 13 and is located on the back side of the preset mold opening side of the lens module. The backrest module 82 is used to abut against the back side of the preset mold opening side of the lens module of the mold opening station 13.

[0060] The tool module 81 extends into the preset mold opening side gap of the lens module to open the lower mold and the upper mold. The lens module is subjected to the mold opening force from the tool module 81, and the backrest module 82 prevents the lens module from detaching from the suction cup module 23 under the action of the mold opening force.

[0061] In this embodiment, a backrest sensor is provided on the backrest module 82 .

[0062] The backrest sensor is a high-precision force sensor to ensure that the backrest module 82 can stop accurately when it just contacts the lens module. At the same time, the backrest sensor detects the subsequent mold opening force, records and analyzes the mold opening status of the lens module, and can verify the detection results of the mold opening detection mechanism, so as to make the judgment of whether to open the mold more accurate. When the force detected by the backrest sensor is greater than the set threshold, the lens module mold opening is unsuccessful, and when the force detected by the backrest sensor is less than the set threshold, the lens module mold opening is successful.

[0063] In the present embodiment, the conveying directions of the upper mold conveying streamline 101, the lower mold conveying streamline 102 and the NG product conveying streamline 103 are parallel, the input end of the upper mold conveying streamline is arranged on the side of the above-mentioned unloading station 14, the input end of the above-mentioned lower mold conveying streamline 102 is arranged between the input end of the above-mentioned upper mold conveying streamline 101 and the above-mentioned unloading station 14, the above-mentioned NG product conveying streamline 103 is arranged on the side of the output end of the above-mentioned lower mold conveying streamline 102 away from the output end of the above-mentioned upper mold conveying streamline 101, the above-mentioned upper mold transfer module 104 is arranged above the above-mentioned lower mold conveying streamline 102, the above-mentioned upper mold transfer module 104 includes a third clamping jaw device 1041, a third clamping jaw translation driving device 1042 and a third clamping jaw flipping driving device 1043, the above-mentioned third clamping jaw device 1041 is used to clamp the upper mold, and the above-mentioned third clamping jaw translation driving device 1042 is used to bring The third clamping jaw device 1041 is moved horizontally between the unloading station 14 and the upper mold conveying line 101, the third clamping jaw flipping driving device 1043 is used to drive the third clamping jaw device 1041 to flip around the horizontal direction so that the upper mold flips 180 degrees and falls on the upper mold conveying line 101, the lower mold transfer module 105 is arranged on the side of the unloading station 14 away from the lower mold conveying line 102, the lower mold transfer module 105 and the NG product transfer module 106 are both pushing modules, the lower mold transfer module 105 is used to push the lower mold or the unsuccessful mold opening lens module on the unloading station 14 to the lower mold conveying line 102 along the horizontal direction, and the NG product transfer module 106 is used to push the unsuccessful mold opening lens module on the lower mold conveying line 102 to the NG product conveying line 103 along the horizontal direction.

[0064] The third clamping jaw device 1041 includes two third clamping jaw rods set at a distance, and the two third clamping jaw rods are clamped on both sides of the lens module. The unloading process of the lens module: the third clamping jaw flipping drive device 1043 drives the third clamping jaw device 1041 to flip, so that the free end of the third clamping jaw rod faces the side where the unloading station 14 is located, and the third clamping jaw translation drive device 1042 drives the third clamping jaw device 1041 to approach the unloading station 14 until the third clamping jaw rod is located on both sides of the upper mold. At this time, the third clamping jaw rod is perpendicular to the vertical axis of the upper mold, and the third clamping jaw device 1041 clamps the upper mold, and the third clamping jaw translation drive device 1042 drives the third clamping jaw device 1041 to move away from the unloading in the horizontal direction. At the work station, the third jaw flipping driving device 1043 drives the third jaw device 1041 to flip 180 degrees clockwise, and the upper mold just falls on the upper mold conveying line 101. The third jaw flipping driving device 1043 drives the third jaw device 1041 to flip 180 degrees counterclockwise, and the lower mold transfer module 105 pushes the lower mold of the tray module 22 or the unsuccessful mold opening lens module to the lower mold conveying line 102, and the NG product transfer module 106 pushes the unsuccessful mold opening lens module on the lower mold conveying line 102 to the NG product conveying line 103.

[0065] In this embodiment, the tray module 22 includes a tray bracket 221, a tray 222 and a tray spring 223. The tray bracket 221 is connected to and fixed to the station circulation module 21. The tray 222 is connected to and can be raised and lowered above the tray bracket 221. The tray spring 223 applies a downward elastic force to the tray 222. After overcoming the elastic force of the tray spring 223, the tray 222 can float upward relative to the tray bracket 221.

[0066] The unloading mechanism 10 includes a push rod module 107 , which is disposed below the unloading station 14 . The push rod module 107 is used to drive the tray 222 on the unloading station 14 to move upward to be flush with the lower mold conveying streamline 102 .

[0067] Since it is difficult to make the tray module 22 flush with the lower mold conveying streamline 102, the lower mold transfer module 105 cannot push the lower mold on the tray module 22 onto the lower mold conveying streamline 102, so a push rod module 107 is provided, and the above-mentioned tray bracket 221 can avoid the push rod module 107, and the push rod module 107 can lift the tray 222, so that the tray 222 is flush with the lower mold conveying streamline 102. The tray bracket 221 is similar in shape to the tray 222, and is connected to the turntable module through four suspension rods 224, which greatly reduces the number and weight of the tray structure.

[0068] In this embodiment, the lower mold conveying streamline 102 is provided with a plurality of lower mold partitions 1021 equidistantly arranged along the conveying direction, the upper mold conveying streamline 101 is provided with a plurality of upper mold partitions 1011 equidistantly arranged along the conveying direction, and the NG product conveying streamline 103 is provided with a plurality of NG product partitions 1031 equidistantly arranged along the conveying direction.

[0069] A lower mold grid room is formed between two adjacent lower mold partitions 1021, and a lower mold is placed in each lower mold grid room. An upper mold grid room is formed between two adjacent upper mold partitions 1011, and an upper mold is placed in each upper mold grid room. An NG product grid room is formed between two adjacent NG product partitions 1031, and an NG product is placed in each NG product grid room. The lower mold partition 1021, the upper mold partition 1011 and the NG product partition 1031 prevent the lens modules from colliding with each other and being damaged.

[0070] In this embodiment, the station circulation module 21 is a turntable module, which drives the module positioning module to revolve around the center of the turntable, and the plurality of stations are evenly arranged around the center of the turntable;

[0071] The above-mentioned workstation mechanism includes a plurality of the above-mentioned module positioning modules, which are installed on the above-mentioned turntable module and evenly arranged around the center of the above-mentioned turntable. The above-mentioned module positioning modules revolve around the center of the above-mentioned turntable and synchronously reach the above-mentioned multiple workstations respectively.

[0072] The turntable module stops once every 360 / N degrees of rotation. When the turntable module rotates 360 / N degrees, multiple module positioning modules are adjusted from the previous station to the next adjacent station along the rotation direction of the turntable module. Different lens modules on multiple module positioning modules perform different tasks synchronously. For example, at the same time, the feeding mechanism 3 transfers the lens module to the module positioning module of the feeding station 11, the mold opening mechanism 8 opens the lens module on the module positioning module on the mold opening station 13, and the unloading mechanism 10 transfers the lens module on the module positioning module on the unloading station 14. By installing multiple module positioning modules on the turntable module, the mold opening efficiency of the mold opening machine is higher, space is saved, the weight of the structure is greatly reduced, the strength and precision of the structure are improved, the assembly is more convenient, and the cost is lower.

[0073] In this embodiment, the suction cup module 23 includes a suction cup bracket, a suction cup 232, and a suction cup lifting drive device 233. The suction cup 232 is used to suck the lens module together. The suction cup lifting drive device 233 is connected to the suction cup bracket and is used to drive the suction cup 232 to rise and fall in the vertical direction.

[0074] By providing a suction cup bracket, a suction cup 232 , and a suction cup lifting drive device 233 , the lens module can be sucked up from the tray module 22 .

[0075] In this embodiment, the suction cup bracket includes a suction cup mounting seat 231, a suction cup floating shaft 234, a first suction cup spring 235 and a second suction cup spring 237. The suction cup mounting seat 231 is connected to the suction cup lifting drive device 233, and the suction cup floating shaft 234 can be lifted and lowered connected to the suction cup mounting seat 231. The first suction cup spring 235 applies a downward elastic force to the suction cup floating shaft 234. After overcoming the elastic force of the first suction cup spring 235, the suction cup floating shaft 234 can float upward relative to the suction cup mounting seat 231. The suction cup 232 is connected to the suction cup floating shaft 234. The second suction cup spring 237 is arranged below the first suction cup spring 235. The second suction cup spring 237 applies an upward elastic force to the suction cup floating shaft 234. The elastic force of the second suction cup spring 237 balances the weight of the suction cup floating shaft 234 and the first suction cup spring 235.

[0076] A limit bracket 238 fixed relatively to the suction cup mounting seat 231 is connected above the suction cup mounting seat 231, a convex ring portion 239 is provided on the suction cup floating shaft 234, a first suction cup spring 235 is provided between the convex ring portion 239 and the limit bracket 238, and a second suction cup spring 237 is provided between the convex ring portion 239 and the suction cup mounting seat 231. By providing the suction cup floating shaft 234, the first suction cup spring 235 and the second suction cup spring 237, the suction cup 232 can float upward adaptively and balance the weight. For example, when the suction cup 232 is sucking the lens module, if the contact force between the two is too large, the suction cup 232 can float upward, so that the contact force between the suction cup 232 and the lens module is maintained within a set range. In particular, when the mold is opened, the weight applied to the lens module by the module positioning module can be reduced, thereby reducing the bending moment borne by the upper mold when the mold is opened. The suction cup floating shaft 234 extends in the vertical direction, and the first suction cup spring 235 and the second suction cup spring 237 are compression springs, which are sleeved on the suction cup floating shaft 234 .

[0077] In this embodiment, the above-mentioned equipment unit includes an anti-breakage detection mechanism 4, which is close to the above-mentioned loading station 11 and is used to detect the position of the fragile area on the upper surface of the upper mold on the above-mentioned loading station 11; the above-mentioned suction cup module also includes a suction cup rotation drive device 236, and the above-mentioned suction cup rotation drive device 236 drives the lens module to rotate in a vertical direction according to the position of the fragile area on the upper surface of the upper mold on the above-mentioned loading station 11 so that the fragile area on the upper surface of the upper mold leaves the preset mold opening side of the lens module.

[0078] Since the lower mold and upper mold of the lens module are made of tempered glass, if there are defects on the surface, it will have stress concentration. Characters are engraved on the lower mold and upper mold of the lens module. The character engraving area on the lower surface of the upper mold is a fragile area. If the character engraving area on the lower surface of the upper mold contacts the tool module 81 when the mold is opened, it is easy to break. In order to prevent the fragile area of ​​the upper mold from contacting the tool module 81, it is necessary to avoid the character engraving area on the lower surface of the upper mold from facing the tool module 81 when it reaches the mold opening station 13. By detecting the character engraving area on the upper surface of the upper mold at the loading station 11, the position of the character engraving area on the lower surface of the upper mold is obtained (the character engraving area on the lower surface of the upper mold is relative to the character engraving area on the upper surface of the upper mold), and then the angle of the lens module around the vertical direction is adjusted to ensure that when the lens module reaches the mold opening station, the fragile area of ​​the upper mold avoids the tool module 81 to prevent the upper mold from breaking when the mold is opened. Lens module self-rotation adjustment process: After the suction cup module 23 sucks up the lens module, it drives the lens module to rotate around the vertical direction by a certain angle.

[0079] In the present embodiment, the anti-shattering detection mechanism 4 comprises an anti-shattering visual detection camera 41 and a light source 42. The anti-shattering visual detection camera 41 is arranged at an angle above the loading station 11 and located at a preset mold opening side of the lens module. The light source 42 is a curved light source. The light source 42 is arranged at an angle above the loading station 11 and located at the back of the preset mold opening side of the lens module. The anti-shattering visual detection camera 41 and the light source 42 cooperate with each other so that the light intensity reflected from the upper mold of the loading station 11 to the anti-shattering visual detection camera 41 is greater than the light intensity reflected from the lower mold of the loading station 11 to the anti-shattering visual detection camera 41.

[0080] Since the character engraving area of ​​the upper mold has a different appearance from other areas, the position of the character engraving area of ​​the upper mold can be detected by visual inspection. Visual inspection has the advantages of high precision, high efficiency, low cost, objectivity and safety. There are characters on both the lower mold and the upper mold, so there will be strong interference. Therefore, the use of curved light sources can effectively reduce the impact of the lower mold and other interference factors on the upper mold imaging. Specifically, the angle between the shooting direction of the anti-breakage visual inspection camera 41 and the vertical direction is 15-60 degrees, the shooting distance from the anti-breakage visual inspection camera 41 to the upper surface of the upper mold is 150 mm, the angle between the light beam direction of the light source 42 and the vertical direction is 10-30 degrees, and the light source 42 is set at a suitable height. For example, the upper end of the light source 42 is located 90-100 mm above the upper surface of the upper mold, and the lower end of the light source 42 is located 20-25 mm above the lower surface of the lower mold. By utilizing the height difference between the lower mold and the upper mold, the light intensity reflected from the upper mold of the loading station 11 to the anti-breakage visual inspection camera 41 is greater than the light intensity reflected from the lower mold of the loading station 11 to the anti-breakage visual inspection camera 41.

[0081] In this embodiment, the loading mechanism 3 includes a module conveying streamline 31, a module transfer module 32 and a module centering module 33. The module conveying streamline 31 is used to carry the lens module and drive the lens module to approach the loading station 11 in the horizontal direction. The module transfer module 32 is used to transfer the lens module on the module conveying streamline 31 to the tray module 22 of the loading station 11. The module centering module 33 is used to adjust the center of the lens module on the loading station 11 to be on the same vertical straight line as the center of the suction cup module 23 above it.

[0082] The module conveying streamline 31 is a belt conveying streamline, which can continuously and orderly convey the lens module to a position close to the loading station. The module transfer module 32 then transfers the lens module on the module conveying streamline 31 to the tray module 22 on the loading station 11. The module conveying streamline 31 and the module transfer module 32 work together to transfer the lens module to the station mechanism 2 in an orderly manner. Since the suction cup module 23 needs to suck up the lens module on the tray module 22, it is necessary to ensure that the center of the suction cup module 23 and the center of the lens module are located on the same vertical axis. However, due to various errors, when the module transfer module 32 places the lens module on the tray module 22, it cannot ensure that the center of the suction cup module 23 and the center of the lens module are located on the same vertical axis. Therefore, the module centering module 33 can make the center of the suction cup module 23 and the center of the lens module located on the same vertical axis.

[0083] In this embodiment, the output end of the module conveying streamline 31 is arranged on the side of the loading station 11, the module transfer module 32 is arranged above the output end of the module conveying streamline 31, the module centering module 33 is arranged below the loading station 11, and the module transfer module 32 includes a first clamping jaw device 321, a first clamping jaw lifting drive device 322 and a first clamping jaw translation drive device 323. The first clamping jaw device 321 is used to clamp the lens module, and the first clamping jaw lifting drive device 322 is used to drive the first clamping jaw device 321 to lift in the vertical direction. The first clamping jaw translation driving device 323 drives the first clamping jaw device 321 to translate in the horizontal direction between the module conveying streamline 31 and the loading station 11. The module centering module 33 includes a second clamping jaw device 331 and a second clamping jaw lifting driving device 332. The second clamping jaw device 331 and the center of the suction cup module 23 on the loading station 11 are located on the same vertical axis. The second clamping jaw device 331 is used to clamp the lens module. The second clamping jaw lifting driving device 332 is used to drive the second clamping jaw device 331 to move up and down in the vertical direction.

[0084] The first clamping jaw device 321 comprises two groups of first clamping jaw rods arranged at a distance, the plurality of first clamping jaw rods are arranged around the vertical direction, and the lower ends of the plurality of first clamping jaw rods are free ends. The second clamping jaw device 331 comprises two groups of second clamping jaw rods arranged at a distance, the plurality of second clamping jaw rods are arranged around the vertical direction, and the upper ends of the plurality of second clamping jaw rods are free ends. The loading process of the lens module: the first clamping jaw lifting drive device 322 drives the first clamping jaw device 321 downward to the four sides of the lens module. At this time, the first clamping jaw rod is parallel to the axial direction of the lens module. The first clamping jaw device 321 clamps the lens module. The first clamping jaw lifting drive device 322 drives the first clamping jaw device 321 upward. The first clamping jaw translation drive device 323 drives the first clamping jaw device 321 from above the module conveying line 31 to above the tray module 22 of the loading station 11. The first clamping jaw lifting drive device 322 drives the first clamping jaw device 321 downward. The first clamping jaw device 321 releases the lens module, thereby transferring the lens module from the module conveying line 31 to the tray module 22. The process of positioning the lens module: the second clamping jaw lifting drive device 332 drives the second clamping jaw device 331 upward to the periphery of the lens module. At this time, the second clamping jaw rod is parallel to the vertical axis of the lens module. The second clamping jaw device 331 clamps the lens module to center the lens module. When the suction cup module 23 attracts the lens module, the second clamping jaw device 331 releases the lens module, and the second clamping jaw lifting drive device 332 drives the second clamping jaw device 331 downward to leave the periphery of the lens module.

[0085] In this embodiment, the first clamping jaw device 321 is provided with a first displacement sensor and / or the second clamping jaw device 331 is provided with a second displacement sensor, the first displacement sensor is used to detect the displacement of the clamping jaw rod of the first clamping jaw device 321, and the second displacement sensor is used to detect the displacement of the clamping jaw rod of the second clamping jaw device 331.

[0086] Because when the first clamping jaw device 321 clamps the lens module, the two groups of first clamping jaw rods need to move closer to and farther away from each other, and when the second clamping jaw device 331 clamps the lens module, the two groups of second clamping jaw rods need to move closer to and farther away from each other, the diameter of the lens module can be obtained according to the displacement of the first clamping jaw rod and / or the displacement of the second clamping jaw rod, and the detection result of the back detection mechanism can be verified, thereby making the detection of the preset back position of the mold opening side of the lens module more accurate.

[0087] In this embodiment, the tool module 81 includes a tool 811 and a tool translation drive device 812. The tool 811 is used to be inserted into a preset mold side gap of the lens module. The tool translation drive device 812 is used to drive the tool 811 to translate in a horizontal direction close to and away from the mold opening station 13.

[0088] The tool opening process of the tool module 81 is as follows: the tool translation drive device 812 drives the tool 811 close to the mold opening station until the tool 811 is inserted into the preset mold opening side gap of the lens module of the mold opening station to a certain depth. After the mold opening is completed, the tool translation drive device 812 drives the tool 811 away from the mold opening station and returns to its original position.

[0089] In this embodiment, the above-mentioned tool 811 includes a tool seat 8111, a tool head 8112 and a tool head floating spring (not shown in the figure). The above-mentioned tool head 8112 is connected to the above-mentioned tool seat 8111 so as to be able to swing up and down. The above-mentioned tool head floating spring applies an elastic force to the above-mentioned tool head 8112. The above-mentioned tool head 8112 maintains a set posture under the action of the elastic force. After overcoming the above-mentioned elastic force, the above-mentioned tool head 8112 can swing downward relative to the above-mentioned tool seat.

[0090] The cutter head 8112 can swing downward adaptively. For example, when the cutter head 8112 is inserted into the mold gap, if the contact force between the two is too large, the cutter head 8112 can swing downward, so that the contact force between the cutter head and the lens module is maintained within a set range. The cutter head 8112 is set to float, and the cutter head can effectively move with the mold gap, reducing the bending moment of the lens module and the impact of the cutter head 8112 on the lens module. The above-mentioned cutter head is connected to the cutter seat through a hinge shaft, and the above-mentioned cutter head floating spring is a torsion spring, which is sleeved on the above-mentioned hinge shaft.

[0091] In this embodiment, the plurality of workstations further include a detection workstation 12, which is located between the loading workstation 11 and the mold opening workstation 13, and the equipment unit further includes a gap detection mechanism 5, which is arranged on the side of the detection workstation 12 and located on the preset mold opening side of the lens module, and the gap detection mechanism 5 is used to detect the angle and height of the preset mold opening side gap of the lens module on the detection workstation 12;

[0092] The above-mentioned tool 811 also includes a tool rotation drive device 813 and a tool lifting drive device 814. The above-mentioned tool rotation drive device 813 is used to drive the above-mentioned tool 811 to rotate in the horizontal direction according to the angle of the preset mold side gap of the lens module to adjust the blade angle of the above-mentioned tool 811. The above-mentioned tool lifting drive device 814 is used to drive the above-mentioned tool 811 to rise and fall in the vertical direction according to the height of the preset mold side gap of the lens module to adjust the height of the above-mentioned tool 811.

[0093] When the module positioning module stops at the mold opening station 13, the mold opening mechanism 8 performs mold opening on the lens module on the module positioning module of the mold opening station 13. Since the lens module has more or less errors, and the sizes of lens modules of different specifications are different, by setting the detection station 12, the angle and height of the preset mold opening side gap of the lens module are detected at the detection station 12, and the tool 811 can be accurately inserted into the preset mold opening side gap of the lens module, so as to achieve accurate mold opening, improve the mold opening success rate, and prevent the tool module 81 from causing damage to the lens module.

[0094] In this embodiment, the gap detection mechanism 5 includes a gap-finding visual detection camera 51 .

[0095] Since the preset mold side gap of the lens module is different in shape from the rest of the positions, the preset mold side gap of the lens module can be detected by visual inspection. Visual inspection has the advantages of high precision, high efficiency, low cost, objectivity and safety.

[0096] In this embodiment, the equipment unit further includes a back detection mechanism 6, which is arranged on the side of the detection station 12 and located on the back of the preset mold opening side of the lens module. The back detection mechanism 6 is used to detect the position of the back of the preset mold opening side of the lens module on the detection station 12;

[0097] The backrest module 82 includes a backrest 821 and a backrest translation drive device 822. The backrest 821 is used to abut against the back side of the preset mold opening side of the lens module. The backrest translation drive device 822 drives the backrest 821 to translate in the horizontal direction close to and away from the mold opening station 13 to adjust the position of the backrest 821.

[0098] When the module positioning module stops at the mold opening station 13, the mold opening mechanism 8 opens the mold of the lens module on the module positioning module of the mold opening station 13. Since the lens module has more or less some errors, and the sizes of lens modules of different specifications are different, the position of the preset mold opening side back of the lens module is detected at the detection station 12, and the backrest 821 can adjust its position and can just abut against the preset mold opening side back of the lens module of the mold opening station 13 to prevent damage to the lens module. The backrest adjustment process of the backrest module: the backrest translation drive device 822 drives the backrest 821 to translate to the position just in contact with the lens module. After the tool module 81 completes the mold opening, the backrest translation drive device 822 drives the backrest 821 away from the lens module.

[0099] In this embodiment, the back side detection mechanism 6 includes a distance sensor 61 .

[0100] The back detection mechanism 6 is relatively fixed to the workbench 1 , so the position of the back of the preset mold opening side of the lens module can be obtained by detecting the distance between the back detection mechanism 6 and the back of the preset mold opening side of the lens module.

[0101] In this embodiment, the equipment unit further comprises a self-opening mold detection mechanism 7 , which is close to the detection station 12 and is used to detect whether the lens module on the detection station 12 is self-opening.

[0102] If the lens module opens by itself during the loading or movement process, the self-opening detection mechanism 7 can directly determine it, thereby preventing the subsequent tool module 81 from opening an empty tool.

[0103] In the present invention, the preset mold opening side of the lens module is the side away from the center of the turntable, the back side of the preset mold opening side of the lens module is opposite to the preset mold opening side of the lens module, and the back side of the preset mold opening side of the lens module is the side facing the center of the turntable.

The suction cup floating shafts 234 of the suction cup 232 can slide relative to the pulley axial direction of the pulley assembly and can rotate with the pulley. The suction cup rotation drive device 236 is close to the center of the turntable module, which greatly reduces the rotational inertia of the turntable module.
